HAWAII PODIUM PRESENTATION - RESEARCH Kei Sonoda, MD<br />

Proteinuria in Mid-Life and 39-Year All-Cause Mortality; The Honolulu Heart Program.<br />

Kei Sonoda, MD; Gotaro Kojima, MD; Suryadutt Venkat, MD, MPH; Christina Bell, MD; Randi Chen, MS;<br />

Helen Petrovitch, MD; Robert D. Abbott, PhD; G. Webster Ross, MD; J. David Curb, MD, MPH; Kamal<br />

Masaki, MD. Department <strong>of</strong> Internal Medici<br />

Introduction: Previous evidence has shown that proteinuria is an independent risk factor for increased<br />

all-cause mortality, cardiovascular disease, and stroke. However, there have been no long-term<br />

population based studies <strong>of</strong> proteinuria and mortality over 3 decades.<br />

Methods: Established in 1965, the Honolulu Heart Program is a longitudinal cohort study <strong>of</strong> 8,006<br />

Japanese-<strong>American</strong> men from the island <strong>of</strong> Oahu, Hawaii, born 1900-1919. Proteinuria was measured at<br />

mid-life using urine dipsticks during exam 1 (1965-68, n=8,006) and exam 3 (1971-74, n=6860).<br />

Participants were classified as ‘no proteinuria’ if they tested negative at both exams, ‘transient<br />

proteinuria’ if they tested positive at one <strong>of</strong> the exams, and ‘persistent proteinuria’ if they tested<br />

positive at both exams. Follow-up began at the end <strong>of</strong> exam 3, and data on all-cause mortality were<br />

Introduction: Majority <strong>of</strong> acute coronary syndrome “rule out” admissions are discharged the next day<br />

after a negative stress test. We sought to identify these low-risk patients who underwent Myocardial<br />

Perfusion Imaging (MPI), and analyze their course from the perspective <strong>of</strong> test propriety.<br />

Methods: A one year cohort <strong>of</strong> 265 patients admitted with chest pain who underwent MPI was studied<br />

retrospectively. Patients with prior history <strong>of</strong> coronary artery disease (CAD) were excluded. Pretest<br />

probability was calculated using the Diamond and Forrester Score (DFS). The pretest probability at which<br />

a negative test would reduce the post-test probability to

Introduction: Breast cancer in men is rare and constitutes less than 1% <strong>of</strong> all cancers in males. The<br />

objective <strong>of</strong> our study is to compare the presenting characteristics, and survival rates in Caucasian and<br />

African-<strong>American</strong> men with breast cancer.<br />

Methods: We analyzed a retrospective cohort <strong>of</strong> breast cancer patients included in National Cancer<br />

Institute’s Surveillance, Epidemiology, and End Results (SEER) Registry from 1990 to 2007. Seventeen<br />

registries are enrolled in the SEER database and include approximately 26% <strong>of</strong> the US population.<br />

Racial differences in demographic and tumor characteristics at the time <strong>of</strong> diagnosis were compared<br />

using chi-square test. Breast cancer and racial specific survival was compared using Kaplan-Meier<br />

method. Cox proportional hazards regression model was used to determine the independent effect <strong>of</strong><br />

race on survival after adjusting for age <strong>of</strong> patient, stage, grade and receptor status <strong>of</strong> tumor.<br />

Results: We included 2348 men with breast cancer in our study; they were Caucasians (2075), and<br />

African-<strong>American</strong> (273).<br />

A greater proportion <strong>of</strong> African <strong>American</strong> men presenting with breast cancer were younger than 60<br />

years old as compared to Caucasians (46% vs. 31%) p< 0.001. They also more <strong>of</strong>ten presented with<br />

advanced disease (12% vs. 6%), higher grade lesions (34% vs. 29%), tumor size greater than 2 cm (48%<br />

vs. 37%) and lymph node involvement (35% vs. 32%) compared to Caucasians. Tumors were more likely<br />

to be progesterone receptor negative (21% vs. 11%) and estrogen receptor negative (8% vs. 4%). All<br />

Introduction: Sex differences have been observed in the incidences <strong>of</strong> autoimmune disorders as well as<br />

in the cytokine response to immune stimulation. However, very little is understood regarding sex<br />

differences in cytokine response in the setting <strong>of</strong> autoimmune disorders. We sought to explore the sex<br />

differences in cytokine response in patients with rheumatoid arthritis (RA).<br />

Methods: We performed a cross-sectional analysis <strong>of</strong> data from a population-based cohort study <strong>of</strong><br />

patients with RA. Patient information collected included age, RA duration, BMI, CRP, HAQ disability<br />

index, current smoking status, rheumatoid factor positivity, anti-CCP antibody positivity, and RA<br />

medication use. Peripheral blood mononuclear cells (PBMC) from subjects were stimulated with a<br />

variety <strong>of</strong> stimulants to determine their cytokine response. Stimulants included anti-CD3/anti-CD28, CpG<br />

oligonucleotides (CpG), combined cytomegalovirus and Epstein Barr virus lysates (CMV/EBV), phorbol<br />

myristate acetate with ionomycin (PMA/ionomycin), phytohemagglutinin, and combined Staphylococcal<br />

enterotoxins A and B (SEA/SEB). Collected supernatants were analyzed for 17 cytokines using<br />

multiplexed immunoassays. The data were normalized using mixed models with random effects for<br />

subject and plate, to adjust for assay effects. Males and females were compared using linear regression<br />

models on the ranks <strong>of</strong> the cytokine values (due to skewed distributions) with adjustment for the patient<br />

factors listed above.<br />

Results: Our study included 234 females (mean age 59.6 years) and 83 males (mean age 63.3<br />

years). Significant differences (p-value

Introduction: Automated blood culture systems detect bacterial growth at any time. Lab policy requires<br />

technicians to report results <strong>of</strong> a Gram stain to the patients’ physician immediately, resulting in phone<br />

calls <strong>of</strong>ten between 10 PM-6AM. Non-hospital based physicians have asked that these calls be delayed<br />

until the next morning, arguing that initial empiric antibiotic therapy is <strong>of</strong>ten appropriate and is rarely<br />

modified based upon gram stain findings. Hypothesis: Antibiotic therapy started prior to the availability<br />

<strong>of</strong> Gram stain results provides adequate coverage <strong>of</strong> organisms subsequently isolated in > 95% <strong>of</strong> cases.<br />

Methods: This is a retrospective study using 40 consecutive blood culture isolates from bacteremic<br />

events from the month <strong>of</strong> September 2011 that first became positive after 10 PM and before 6 AM in<br />

patients hospitalized at UMC. Gram stain characteristics and culture sensitivity results were recorded.<br />

The antibiotics these patients were receiving during the day <strong>of</strong> or day before the blood culture first was<br />

first positive were recorded. Algorithms were devised to determine if antibiotic therapy would have<br />

been modified based upon patient history, present therapy and Gram stain results. Hypothesis will be<br />

rejected if < 95% <strong>of</strong> cases are on appropriate antibiotic therapy prior to gram stain results.<br />

Results: 1. At the time <strong>of</strong> Gram stain results, 16 out <strong>of</strong> 40 patients had inadequate antibiotic coverage<br />

based upon pre-determined algorithms (4 yeast, 4 gram negative bacilli, others gram positive cocci in<br />

clusters.) i.e. the hypothesis was rejected. 2. Of the 16 patients with inadequate coverage at the time <strong>of</strong><br />

Gram stain, 3 had health care associated problems, one was a lateral transfer from another hospital, one<br />

was a transfer from a rehab facility, and one was immunodeficient. 3. When followed through to the<br />

culture sensitivity 22 had inadequate antibiotic coverage at the time <strong>of</strong> gram stain results. 4. The<br />

modifications suggested by Gram stain based on the algorithm would have corrected the coverage in 13<br />

out <strong>of</strong> the 16 patients. And would have reduced the total number <strong>of</strong> inadequate coverage based on<br />

culture sensitivity to 9 from 22.<br />

Conclusion: Gram stain reporting during <strong>of</strong>f hours should be continued. Special emphasis should be<br />

placed on the patients who are immune-deficient, chronic illnesses requiring hospital care, and transfers<br />

from other health care facilities.<br />

Nuclear PDE1 Induces Vascular Remodeling and Atherosclerosis<br />

David Nagel MD, PhD Toru Aizawa MD, Bradford C. Berk MD, PhD, and Chen Yan PhD<br />

Introduction: According to the CDC, in 2006, 631,636 people died <strong>of</strong> heart disease, and in 2010, it was<br />

estimated that heart disease would cost the United States $316.4 billion. Abnormal vascular smooth<br />

muscle cell (VSMC) growth has been implicated in a multitude <strong>of</strong> cardiovascular diseases, including<br />

stroke, atherosclerosis, and restenosis. Numerous studies have shown that cyclic nucleotides, cAMP and<br />

cGMP, inhibit VSMC proliferation. Phosphodiesterases (PDEs), through inactivation <strong>of</strong> cyclic nucleotides,<br />

play critical roles in controlling intracellular signal transduction. PDE1 is a Ca 2+ /Calmodulin-stimulated<br />

PDE, which hydrolyzes both cAMP and cGMP, but has a higher affinity for cGMP. Because cGMP is a key<br />

mediator <strong>of</strong> VSMC growth, we hypothesized that a nuclear isozyme <strong>of</strong> PDE1 may downregulate cGMP<br />

and promote VSMC growth.<br />

Methods: We utilized rat balloon-injured carotid arteries, murine ligated carotid arteries, and human<br />

coronary arteries (post-mortem), to perform immunohistochemical anaylsis. Morphometric and cell<br />

counting analyses were performed with Image Pro 6.0 s<strong>of</strong>tware. Rat aortic smooth muscle cells (RASM)<br />

were prepared using enzymatic digestion <strong>of</strong> aortas from rats (Sprague-Dawley), and cells were grown in<br />

medium (DMEM) containing 10% fetal bovine serum in a humidified incubator. Fibrillar collagen gels<br />

were made by diluting rat type 1 collagen (PureCol, Inamed) in freshly prepared 7x DMEM<br />

(Cellgro). Monomeric collagen-coated dishes were prepared by diluting the collagen in water and acetic<br />

acid (0.5 N). To prevent collagen denaturation, every step <strong>of</strong> the protocol was performed on ice.<br />

Results: We demonstrated that PDE1 localized to the cytoplasm in quiescent VSMC located in the<br />

medial layer, yet PDE1 was primarily located in the nuclei <strong>of</strong> neointimal VSMC. In addition, by<br />

manipulating the collagen substrate <strong>of</strong> culture dishes, we found that the subcellular location <strong>of</strong> PDE1 is<br />

dependent upon the phenotypic state <strong>of</strong> the VSMC. We demonstrated that VSMC growth was<br />

significantly reduced both in the presence <strong>of</strong> a pharmacological inhibitor (IC86340) and a siRNA that<br />

selectively target PDE1 expression. These phenomena were corroborated with in vivo experiments<br />

whereby neointimal formation was reduced with local administration <strong>of</strong> a PDE1 inhibitor. Finally, similar<br />

experiments were performed with ex-vivo human saphenous vein grafts that were cultured and treated<br />

with PDE1 inhibitors.<br />

Conclusion: These results suggest that nuclear PDE1 may play an important role in regulating VSMC<br />

growth by modulating specific subcellular pools <strong>of</strong> cGMP. Therefore, inhibitors that specifically block the<br />

function <strong>of</strong> nuclear PDE1 may prove to be a novel therapy to maintain VSMC differentiation and<br />

attenuate atherosclerosis development.<br />

Are We Increasing the Risk <strong>of</strong> Stroke by Adding Proton Pump Inhibitors to Clopidogrel? A Systematic<br />

Review and Meta-Analysis<br />

Dany A Raad, MD Co-authors: Keenan Adib, MD, Rabi Yacoub, MD, Lynn Chouhfeh, MD, Eiad Nasser, MD<br />

Introduction: Around 795,000 patients suffer a stroke every year in the US with an estimated direct and<br />

indirect cost <strong>of</strong> 73.7 billion dollars in 2010. Clopidogrel has become a cornerstone in secondary<br />

prevention <strong>of</strong> cardiovascular and cerebrovascular diseases. Many clinicians prescribe proton pump<br />

inhibitors (PPI) with clopidogrel to reduce the risk <strong>of</strong> gastrointestinal bleeding. Recent evidence suggests<br />

that PPI attenuate the antiplatelet effects <strong>of</strong> clopidogrel. Most studies that analyzed the effect <strong>of</strong><br />

concomitant use <strong>of</strong> PPI and clopidogrel focused on cardiovascular outcomes and mortality. Only few<br />

studies have analyzed the effects <strong>of</strong> this concomitant use on cerebrovascular outcomes, and were<br />

mostly observational and limited in numbers. The objective <strong>of</strong> this study was to systematically review<br />

the effect <strong>of</strong> adding PPI to clopidogrel on the risk <strong>of</strong> ischemic stroke.<br />

Methods: We searched in October 2011 the following electronic databases starting with their dates <strong>of</strong><br />

inception: MEDLINE, EMBASE, Web <strong>of</strong> Science, and Healthstar, in addition to abstracts <strong>of</strong> pertinent<br />

scientific meetings (ACC, AHA, DDW, ACG, AAN and ISC; 2006-2011). Two investigators screened title<br />

and abstracts then full text in duplicate and independently. We included both observational and<br />

randomized controlled trials (RCT) in the search. The primary outcome was occurrence <strong>of</strong> ischemic<br />

stroke. We analyzed data using Stata and Review Manager. We used odds ratio (OR) to evaluate the risk<br />

and I 2 test to evaluate study heterogeneity. The results were presented using forest plot. Analysis was<br />

performed using random effects estimate. Publication bias was calculated using Egger’s test.<br />

Results: We reviewed 1803 publications and found 14 relevant studies that included stroke as an<br />

outcome: 3 had insufficient data; 9 were published as full texts and 2 as abstracts. All studies were<br />

observational and no RCT was found. A total <strong>of</strong> 119,925 patients were included <strong>of</strong> which 32,716 were on<br />

clopidogrel + PPI and 87,209 were on clopidogrel alone. The addition <strong>of</strong> PPI to clopidogrel significantly<br />

increased the risk <strong>of</strong> ischemic stroke (OR = 1.39, 95% CI = 1.17 – 1.65, p < 0.001), heterogeneity was<br />

found across the studies (I 2 = 52%, p = 0.02), and no publication bias was found (Bias Coefficient = -0.95,<br />

95% CI = -3.94 to 2.05, p = 0.47).<br />

Conclusion: This meta-analysis found that adding PPI to clopidogrel increases the risk <strong>of</strong> ischemic stroke.<br />

To our knowledge, this is the first meta-analysis studying the concomitant use <strong>of</strong> PPI and clopidogrel and<br />

its effect on ischemic stroke. Well powered randomized clinical trials are warranted to confirm this<br />

finding.<br />

Routine Backup Testing for Negative Rapid Antigen Detection Testing (RADT) in the Management <strong>of</strong><br />

Acute Pharyngitis in Adults has Little Value and is Expensive<br />

Georges Nakhoul, MD All Authors: Georges Nakhoul MD, John Hickner MD, MSc<br />

Introduction: The diagnosis <strong>of</strong> Group A beta-hemolytic streptococcal pharyngitis is based on a<br />

combination <strong>of</strong> clinical scores such as the Centor criteria and point <strong>of</strong> care rapid antigen detection tests<br />

(RADT). In adults, a confirmatory culture <strong>of</strong> a negative RADT is not mandatory but it is widely done in<br />

clinical practice. Our hypothesis is that the routine backup testing for negative RADT adds costs with<br />

minimal clinical benefit.<br />

Methods: Using the electronic medical record database, we performed an audit <strong>of</strong> patients over 18<br />

years old presenting to Cleveland Clinic primary care <strong>of</strong>fices in 2009 & 2010 that had a primary diagnosis<br />

<strong>of</strong> acute pharyngitis (ICD codes 462, 034.0). We determined the number <strong>of</strong> patients that had a negative<br />

RADT (Acceava is the RADT used at the Cleveland Clinic) and a positive confirmatory test (DNA probe for<br />

group A beta hemolytic strep, which is equivalent to culture). We calculated the specificity and negative<br />

predictive value <strong>of</strong> the RADT using DNA probe as the gold standard. We also determined whether a<br />

subsequently positive DNA probe lead to a change in therapy.<br />

Results: From a total <strong>of</strong> 25,130 patients with pharyngitis, 4,708 had no testing (18.7%) and 20,422<br />

(81.3%) were tested by RADT alone (3520 patients), DNA probe alone (832 patients) or both (16071<br />

patients). Of the 15,554 patients that had a negative RADT and follow up DNA probe, 93.9% had a<br />

negative DNA probe yielding a RADT specificity <strong>of</strong> 97.3% and a negative predictive value <strong>of</strong> 93.9%. Of the<br />

953 patients who had a negative RADT and a positive DNA probe, 19.6% were prescribed an antibiotic<br />

before the DNA probe test results were available, and 33.8% received an antibiotic prescription in the<br />

week following the initial <strong>of</strong>fice visit. 46.6% were not prescribed an antibiotic even after the DNA probe<br />

test returned positive. Of the 15,554 patients that had a negative RADT, management was altered in<br />

only 2.1% patients, at a total cost <strong>of</strong> $1,602,062, or $4,975 per change in patient therapy.<br />

Conclusion: The RADT we use at Cleveland Clinic (Acceava) has an excellent specificity and negative<br />

predictive value. As used by Cleveland Clinic physicians, routine back-up testing lead to change <strong>of</strong><br />

management in only 2.1% <strong>of</strong> the patients at a total cost <strong>of</strong> $1,602,062. Using a chart audit we will<br />

evaluate the potential negative consequences for the 444 patients with a negative RADT but positive<br />

DNA probe who were not treated with an antibiotic.<br />

Early Intravenous (IV) To Oral (PO) Azithromycin Conversion in Hospitalized Patients with Community<br />

Acquired Pneumonia (CAP).<br />

Julian Nahuel Diaz Fraga, MDArchana Satyal-Chaudhary, MD Andrew Crocker, MD Shuchi Gulati, MD<br />

Gaurav Gulati, MD Anup Subedee, MD David George, MD.<br />

Introduction: Many patients admitted with community-acquired pneumonia (CAP) continue to receive<br />

IV antibiotics for longer than necessary. Early conversion from IV to PO route has been reported to<br />

increase patient safety and comfort, reduce cost, and facilitate earlier discharge, without compromising<br />

medical care. We developed an intervention strategy to decrease the time from IV to PO conversion <strong>of</strong><br />

azithromycin therapy for CAP in hospitalized patients by 20% over a 3 month period.<br />

Methods: This resident-led quality improvement project was conducted in a 750-bed community<br />

teaching hospital in which all medications are ordered online. We created a radio button option added<br />

to electronic CAP order set to allow physicians to preauthorize pharmacists to convert IV to PO<br />

azithromycin for patients meeting certain criteria. Hospitalist and resident staff received real time<br />

feedback to reinforce education and address variation in practice patterns. Pharmacy developed a<br />

system <strong>of</strong> rapid identification <strong>of</strong> candidates for antibiotic conversion. Pre- and post-intervention<br />

measures included time to conversion from IV to PO antibiotic dosing, length <strong>of</strong> stay, rates <strong>of</strong><br />

readmission, death, transfer to a higher level <strong>of</strong> care, and reconversion to IV antibiotic therapy. Baseline<br />

and final statistics were collected via electronic health record (EHR) chart review.<br />

Results: The average time from IV to PO azithromycin conversion was decreased by more than 50% (1 ½<br />

days) after our intervention. A direct cost savings was estimated to be $17,500 per year and nursing<br />

time reduced by 19.4 days /year (estimate extra 10 minutes per IV administration.) There was no<br />

statistically significant difference in the length <strong>of</strong> stay, rates <strong>of</strong> readmission, death, transfer to a higher<br />

level <strong>of</strong> care, and reconversion to IV antibiotic therapy. Physician acceptance was excellent, and the<br />

process has been extended to the COPD order set.<br />

Conclusion: A simple change in process substantially reduces time from IV to PO azithromycin<br />

conversion in hospitalized patients with CAP, without compromising medical care. The process reduces<br />

cost and saves nursing time. In order to impact length <strong>of</strong> stay, the team will develop the current<br />

program to standardize discharge criteria and define appropriate oral antibiotic choice in this era <strong>of</strong><br />

increased pneumococcal resistance to azithromycin.<br />

Introduction: Congestive hepatopathy leading to abnormal liver function tests (LFTs) is a common<br />

finding in patients with acute decompensated heart failure (HF). The aim <strong>of</strong> this study was to determine<br />

the prognostic significance, if any, <strong>of</strong> abnormal LFTs in acute decompensated heart failure, as this has<br />

not been extensively studied so far.<br />

Methods: A retrospective chart review <strong>of</strong> all adult patients (> 18years <strong>of</strong> age) who were admitted to a<br />

community hospital with a diagnosis <strong>of</strong> acute decompensated HF during the period from Jan 1, 2008 to<br />

June 30, 2010 was performed. Of the 187 patients identified, 170 patients were included in the study.<br />

Exclusion criteria included insufficient laboratory data, acute/chronic kidney injury (serum creatinine ><br />

2mg/dl), acute myocardial infarction, hepatitis (drug-induced/infectious), malignancy and death from<br />

any cause other than HF. Primary end points <strong>of</strong> the study were readmission or death secondary to<br />

HF. The Cox proportional hazard model was used for statistical analysis <strong>of</strong> the data. p values = 0.05 were<br />

considered statistically significant.<br />

Results: The mean age <strong>of</strong> the patients was 78.5 years. Of the 170 patients, 42% were male and 122 were<br />

readmitted secondary to HF during the study period. Serum total bilirubin (p 1.3 mg/dl on admission or an EF < 35% collectively<br />

Border-Crossers' Nephropathy: The Risk <strong>of</strong> Coming to America<br />

Nduka-obi Ossai, MD, Harold M. Szerlip, MD.<br />

Introduction: The 380 mile border between Mexico and Arizona has become a prime entry point for<br />

persons wanting to enter the United States. Because <strong>of</strong> increased enforcement, these individuals usually<br />

attempt to cross the border in desolate areas where they may wander for days without food or water<br />

before being "rescued". The summer <strong>of</strong> 2010 was one <strong>of</strong> the five hottest summers on record. During<br />

2010, 232 individuals died trying to cross the border into Arizona and 212,202 people were<br />

apprehended in the Tucson Sector. The University <strong>of</strong> Arizona Medical Center, South Campus is one <strong>of</strong><br />

the closest tertiary care medical centers to the Mexican border. Detainees with medical problems are<br />

frequently brouqht to this campus. Herein we describe our experience with Myoglobinuric acute kidney<br />

injury (AKI) in these border-crossers.<br />

Methods: We reviewed the records <strong>of</strong> all border crossers admitted between June 1, 2010 - June 30,<br />

2011 with AKI as defined by AKIN criteria who also had an elevation <strong>of</strong> CPK > 1000 IU/L. We recorded<br />

the age, gender, temperature, days in the desert, serum creatinine on presentation, CPK on<br />

presentation, days in the desert, need for dialysis, length <strong>of</strong> hospital stay and serum creatinine on<br />

discharge.<br />

Results: During this time period 42 people were diagnosed with Myolobinuric AKI. On presentation all<br />

patients were vigorously resuscitated with either 0.9% NaCI or a mixture <strong>of</strong> NaCI and NaHC03. The mean<br />

age was 32.5 years (range 18-53). 38 were male and 4 female. They had wandered in the desert<br />

between 1 and 10 days with a mean <strong>of</strong> 4.2 days. Seven had stage 1 AKI, 10 stage 2 and 25 stage 3. Five<br />

patients required dialysis. Only 1 patient had a temperature> 100.6F on arrival. CPKs ranged between<br />

1101 and 447,966 IU/L. Length <strong>of</strong> stay was between 1 and 17 days with a mean <strong>of</strong> 4.0 days. Two patients<br />

were discharged on hemodialysis and 8 were discharged with serum creatinine >1.3 mg/dl.<br />

Conclusion: This is the largest series <strong>of</strong> Myoglobinuric AKI reported in border-crossers. The presumed<br />

etiology is excessive heat combined with volume depletion and stressful exercise. We have coined the<br />

term "border-crossers nephropathy" for this disorder. Many <strong>of</strong> these patients may develop CKD and<br />

require nephrology care in their home country.<br />

MD, PhD (Cardiology)<br />

Introduction: Previous studies have suggested worse outcomes for patients admitted with acute<br />

myocardial infarction (AMI) on weekends. Only limited availability <strong>of</strong> resources on weekends has been<br />

thought <strong>of</strong> as the major causative factor. In general, improvements in system based practices and push<br />

to reduce the door to balloon time has contributed towards better outcomes <strong>of</strong> AMI. Nonetheless, there<br />

are no data on trends in outcomes <strong>of</strong> AMI patients hospitalized on weekends in recent years.<br />

Methods: This was a cross sectional study using the Nationwide Inpatient Sample from the years 2000<br />

to 2008. A total <strong>of</strong> 5,848,502 discharges with AMI and its related revascularization procedures were<br />

Vincent Kao, DO MS, Behnam Saberi, MD, Maria D Ybanez, William Gaarde, Derick Han, PharmD, Neil<br />

Kaplowitz, MD<br />

Introduction: Acetaminophen (APAP) is the most common cause <strong>of</strong> drug induced liver injury (DILI).<br />

Traditionally, hepatotoxicity <strong>of</strong> APAP had been believed to the result <strong>of</strong> cellular injury caused by NAPQI,<br />

a reactive metabolite <strong>of</strong> APAP formed by the actions <strong>of</strong> cytochrome P450. However, recent studies from<br />

our lab have shown that activation <strong>of</strong> signal transduction pathways including JNK is required for APAPinduced<br />

liver injury to occur. We had previously shown that inhibition <strong>of</strong> protein kinase C (PKC) protects<br />

against hydrogen peroxide (H2O2) induced necrosis in primary culture hepatocyte (AJP 2008<br />

Jul;295(1):C50-63). In this work we investigated the possible role <strong>of</strong> PKC in APAP-induced liver injury.<br />

Methods: Hepatocytes were isolated from C57 BL/6 mice and plated on 60mm culture dishes. After the<br />

culture medium was changed to serum free medium, the hepatocytes were then treated with various<br />

inhibitors, such as PKC inhibitors. After 16 h <strong>of</strong> various treatments, cells were double stained with<br />

Hoechst 33258 and Sytox green. Culture dishes were then observed under an OLYMPUS fluorescent<br />

microscope. Quantitation <strong>of</strong> total and apoptotic cells was performed and necrotic cells (Sytox green<br />

positive) were determined by counting the same field. Aliquots from cytoplasm or membrane<br />

extracts were fractionated on SDS-PAGE gel (Bio-Rad), and proteins were transferred to membranes<br />

and visualized by immunoblot analysis using antisera for PKC-a (obtained from Cell Signaling<br />

Technologies, Danvers, MD). Antisense oligonucleotides (ASO) targeting mouse PKC-a and a chemical<br />

control oligonucleotide (Isis Pharmaceuticals, Carlsbad, CA) were synthesized as 20-nt uniform<br />

phosphorothioate chimeric oligonucleotides that support RNase H-based cleavage <strong>of</strong> the targeted<br />

mRNA. To knockdown PKC-a, mice were injected intraperitoneally with ASO seven times (50 mg/Kg<br />

every other day).<br />

Results: The treatment <strong>of</strong> APAP to mice appears to primarily activate PKC-a in the liver. The activation <strong>of</strong><br />

PKC-a occurs early (within 1 hour) with a time course very similar to JNK activation in the liver. PKC<br />

activation appears to mediate APAP hepatotoxicity both in cultured primary hepatocytes and in vivo.<br />

Pre-treatment <strong>of</strong> primary cultured hepatocytes with PKC inhibitors (Ro-31-8425 or Go6983) significantly<br />

decreased necrosis caused by APAP (~52% and 29% respectively). Similarly, pretreatment with PKC<br />

inhibitor (Ro-31-8425) to mice significantly protected against APAP-induced liver injury. The importance<br />

<strong>of</strong> PKC-a mediating APAP-induced liver injury was confirmed using antisense oligonucleotide (ASO).<br />

Silencing PKC-a using ASO significantly protected against APAP-induced liver injury in mice. We are<br />

presently investigating the interplay between PKC-a and JNK in mediating APAP-induced liver injury.<br />

Conclusion: Our data suggests that PKC-a activation plays an important role in APAP induced liver injury.<br />

The inhibition <strong>of</strong> PKC-a may represent a new therapeutic target to prevent APAP hepatotoxicity and<br />

possibly other drugs that cause DILI.<br />

Bacterial Infections in Patients with End Stage Renal Disease<br />

Theresa L. Nilson, M.D. (Associate) Yuichi Masuda, M.D., Ph.D. Hirohito Ichii, M.D. Nosratola D. Vaziri,<br />

M.D.<br />

Introduction: Bacterial infections are the second most common cause <strong>of</strong> death in patients with end<br />

stage renal disease (ESRD). This is largely due to uremia-induced immune the deficiency which is caused<br />

by dendritic cell depletion and dysfunction, T and B lymphocyte abnormalities and impaired phagocytic<br />

<strong>of</strong> polymorphonuclear leukocyte (PMNs). Intravenous (IV) iron preparations are commonly used in the<br />

management <strong>of</strong> anemia in ESRD patients. Recently the use <strong>of</strong> IV iron preparations in ESRD patients has<br />

dramatically increased in order to lower the requirement for erythropoiesis stimulating agents (ESA). In<br />

many instances IV iron preparations are administered on a routine basis with insufficient attention to<br />

the total body iron stores. Iron overload is associated with increased incidence <strong>of</strong> bacterial infections in<br />

patients with and without ESRD and IV administration <strong>of</strong> iron sucrose in ESRD patients has been shown<br />

to impair phagocytic and bacteriocidal capacity <strong>of</strong> PMNs against E. Coli. IV iron preparations consist <strong>of</strong> a<br />

core <strong>of</strong> elemental iron covered by a carbohydrate shell. In addition to the elemental iron, the<br />

carbohydrate shell <strong>of</strong> these compounds may potentially affect PMNs and monocytes. The present study<br />

was designed to examine the effect <strong>of</strong> one <strong>of</strong> the commonly used IV iron preparations, iron sucrose, on<br />

the phagocytic capacity <strong>of</strong> PMNs from a group <strong>of</strong> normal individuals against Gram positive<br />

(Staphylococcus aureus) and Gram negative (Escherichia coli). To this end iron sucrose was added to<br />

heparinized blood samples from each subject at pharmacologically-relevant concentrations and<br />

incubated for 4 hr and 24 hr at 37º C to simulate in vivo condition. Blood samples mixed with equal<br />

volume <strong>of</strong> saline solution served as controls. To isolate the possible effect <strong>of</strong> the complex carbohydrate<br />

shell from that <strong>of</strong> the elemental iron core <strong>of</strong> the drug, blood samples were simultaneously treated with<br />

iron sucrose and the iron chelator, desferrioxamine. The study showed that iron sucrose causes a<br />

significant concentration- and time-dependent suppression <strong>of</strong> phagocytic activities <strong>of</strong> PMNs against<br />

both Gram positive and Gram negative bacteria. Iron sucrose induced suppression <strong>of</strong> PMN phagocytic<br />

activity was prevented by the iron chelator, desferrioxamine, thus precluding the contribution <strong>of</strong> the<br />

carbohydrate shell <strong>of</strong> iron sucrose to the PMN dysfunction. Thus, at pharmacologically-relevant<br />

concentrations iron sucrose significantly inhibits phagocytic activities <strong>of</strong> PMNs against both Gram<br />

positive and Gram negative bacteria. The deleterious effect <strong>of</strong> iron sucrose was mediated by its<br />

elemental iron core but not to its carbohydrate shell and as such may be shared by other IV iron<br />

preparation.<br />

The Role <strong>of</strong> the Retinoblastoma/E2F1 Tumor Suppressor Pathway in the Lesion Recognition Step <strong>of</strong><br />

Nucleotide Excision Repair<br />

Patrick S. Lin, Lisa McPherson, Aubrey Chen, Julien Sage, James Ford<br />

Introduction: The retinoblastoma Rb/E2F tumor suppressor pathway plays a major role in cell cycle<br />

regulation. The pRb protein, along with p107 and p130, exerts its anti-proliferative effects by binding to<br />

the E2F family <strong>of</strong> transcription factors known to regulate essential genes throughout the cell<br />

cycle. Given that cell cycle and DNA repair are intimately linked, we sought to investigate the role <strong>of</strong> the<br />

Rb/E2F1 pathway in nucleotide excision repair (NER) in mouse embryonic fibroblasts (MEFs).<br />

Methods: Rb-/- and Rb-/-;p107-/-;p130-/- MEFs were used in our study. Repair <strong>of</strong> cyclobutane<br />

pyrimidine dimers (CPDs) and 6-4 pyrimidine-pyrimidone photoproducts (6-4PPs) at different times<br />

following UV-C (254nm) irradiation was measured using ELISA. Real time RT-PCR was used to evaluate<br />

specific NER transcripts. Putative E2F1 binding sites were determined using a rigorous algorithm<br />

(http://compel.bionet.nsc.ru/FunSite/SiteScan.html). Chromatin immunoprecipitation assays were<br />

performed to establish E2F1 binding to putative promoters.<br />

Results: Rb-/-;p107-/-;p130-/- MEFs repaired both CPDs and 6-4PPs at higher efficiency than did<br />

wildtype cells following UV-C irradiation. The expression <strong>of</strong> damaged DNA binding gene DDB2 involved<br />

in the DNA lesion recognition step was elevated in the Rb family-deficient MEFs. Conversely, E2F1-/-<br />

MEFs were impaired for the removal <strong>of</strong> both CPDs and 6-4PPs. Furthermore, wildtype cells induced a<br />

higher expression <strong>of</strong> DDB2 and xeroderma pigmentosum gene XPC transcript levels than did E2F1-/-<br />

cells. ChIP assays confirmed the binding <strong>of</strong> E2F1 to a novel XPC promoter in a UV-dependent manner,<br />

suggesting that E2F1 is a transcriptional regulator <strong>of</strong> XPC.<br />

Conclusion: The discovery <strong>of</strong> a regulatory function <strong>of</strong> E2F1 in the NER pathway demonstrates a novel<br />

role for E2F1 in DNA repair in addition to its well-established functions in cell cycle checkpoint, cell cycle<br />

progression, and apoptosis. Specifically, our study demonstrates that E2F1 is involved in the regulation<br />

<strong>of</strong> DNA lesion recognition factors DDB2 and XPC in mouse NER, suggesting a role <strong>of</strong> E2F1 not only as a<br />

responder <strong>of</strong> DNA damage but also as an effector <strong>of</strong> DNA repair. Most importantly, a thorough<br />

understanding <strong>of</strong> the mechanism by which the Rb/E2F1 tumor suppressor pathway regulates NER will<br />

provide valuable insights into potential targets for therapeutic intervention in the treatment against<br />

cancer.<br />

Employment <strong>of</strong> a Standardized Management Strategy for Asymptomatic Distal Deep Venous<br />

Thrombosis in the ICU.<br />

Benton Ashlock, MD and Kenneth Serio, MD<br />

Introduction: With the increased use <strong>of</strong> Doppler ultrasound to screen for deep venous thombosis (DVT),<br />

the incidence <strong>of</strong> asymptomatic or incidental below-knee (distal) DVT is increasing in the ICU. Currently,<br />

there is a paucity <strong>of</strong> evidence to guide appropriate management once distal DVT is discovered. Eightyeight<br />

percent <strong>of</strong> distal DVT in our institution are diagnosed in the ICU. Employing a standardized<br />

management strategy in the ICU, we sought to determine the natural history <strong>of</strong> distal DVT, determine<br />

the rate <strong>of</strong> progression from distal to proximal DVT, determine if the presence <strong>of</strong> distal DVT alters<br />

physician behavior (with regard to DVT prophylaxis), and to determine risk factors to help predict which<br />

patients will undergo progression from distal to proximal DVT in this clinical setting.<br />

Methods: A single institution prospective observational trial was conducted. Patients admitted to the<br />

ICU at Scripps Clinic Green Hospital between 10/2008-10/2010 were studies utilizing a uniform DVT<br />

management strategy. All medical ICU patients (with clinical indications) were screened for DVT with<br />

lower extremity Doppler ultrasound studies within 24 hrs <strong>of</strong> ICU admission and every 7 days. Patients<br />

with progression to proximal DVT or pulmonary embolism (PE) were identified and treated per the usual<br />

standard <strong>of</strong> care. Seventy-seven patients with isolated asymptomatic calf DVT were enrolled and<br />

underwent repeat lower extremity Doppler evaluation every 48 hours for a total <strong>of</strong> 12 days. Patients<br />

were subsequently followed for a total <strong>of</strong> 30 days via the institution’s electronic medical record to<br />

monitor for diagnosis <strong>of</strong> subsequent proximal DVT or PE.<br />

Results: Among the 77 subjects, 58% completed the 6 subsequent Doppler evaluations. Fifty percent <strong>of</strong><br />

distal DVT were diagnosed on the initial screen while the remaining 50% were identified 24 hrs or later<br />

after ICU admission. Ten <strong>of</strong> 77 (13.0%) experienced progression to proximal DVT, and one was found<br />

incidentally to have PE. Mean/median latency to progression was 10.8/8.0 days. In 27.3% <strong>of</strong> the distal<br />

DVT diagnosed cases, the physician increased the extent <strong>of</strong> either pharmacologic or mecanical DVT<br />

prophylaxis in response to the positive study result. Risk factors including time <strong>of</strong> diagnosis, femoral<br />

central catheter presence, history <strong>of</strong> cancer, race, and primary diagnosis were not predictive <strong>of</strong> the rate<br />

<strong>of</strong> progression. The only risk factors that reached significance were the history <strong>of</strong> DVT/PE and female<br />

sex. 30-day mortality was nearly double in patients who progressed, 25% vs. 13%.<br />

Conclusion: Distal DVT’s constitute some risk for thomboembolic disease; however most <strong>of</strong> our patients<br />

did not progress to proximal DVT despite the decreased mobility <strong>of</strong> hospitalization and ICU care. Risk<br />

factors commonly assumed to be associated with thromboembolic disease we largely equal in both<br />

groups. The incidental diagnosis <strong>of</strong> pulmonary embolism demonstrated the heterogeneity <strong>of</strong> treatment<br />

between hospitals and the need for clear guidelines with in the management <strong>of</strong> distal DVT. Prophylaxis<br />

was increased in response to diagnosis <strong>of</strong> distal DVT which likely demonstrates appropriate prophylaxis<br />

was being unnecessarily avoided. The complete lack <strong>of</strong> clinically significant thromboembolic disease<br />

reiterates the appropriateness <strong>of</strong> the retracted recommendation to monitor distal DVT’s with serial<br />

doppler ultrasound to avoid unnecessary anticoagulation as well as to catch and treat patients who do<br />

progress from distal to proximal DVT.<br />

Variations in the Linkage <strong>of</strong> Care <strong>of</strong> Newly Diagnosed Human Immunodeficiency Virus (HIV) at a<br />

Veterans Administration (VA) Hospital<br />

Lueng Tcheung, Matthew Goetz<br />

Introduction: In the VA Healthcare System, patients have access to healthcare that is not limited by lack<br />

<strong>of</strong> income. Nonetheless, variations in care may persist. In response to VA initiatives to increase testing<br />

for HIV, we have sought to assess factors associated with variations in receipt <strong>of</strong> care in persons newly<br />

found to be HIV infected.<br />

Methods: We reviewed electronic medical records <strong>of</strong> 170 patients newly diagnosed as HIV-infected<br />

from October 1998 through March 2011 at the Greater Los Angeles Veterans Administration Healthcare<br />

System. The principle outcome measures were the time from testing positive to result notification, first<br />

infectious disease (ID) clinic appointment and to initiation <strong>of</strong> antiretroviral therapy (ART). Covariates <strong>of</strong><br />

interest included age, race, housing status and whether testing was done after July 2005 when a new<br />

initiative to promote HIV testing was implemented.<br />

Results: For 165 patients the median quartile time from positive test to result notification was 11 days; 5<br />

had no further follow-up in the WLAVA system. Of these 165 patients, 134 (81%) had an ID appointment<br />

within three months <strong>of</strong> a reactive HIV test. Within three months from the date that the patient had their<br />

Outcomes <strong>of</strong> Older Patients who Initiate Chronic Dialysis in the Inpatient Setting.<br />

Susan Wong, MD William Kreuter, MPA Ann M. O’Hare, MD MA<br />

Introduction: Older adults represent the fastest growing contingent <strong>of</strong> the population starting chronic<br />

dialysis for end-stage renal disease (ESRD). Initiating chronic dialysis during hospitalization for acute<br />

illness is unfavorable but common in older adults, and their prognosis is largely unknown.<br />

Methods: We used data from a national registry on ESRD to conduct a retrospective study on 585,291<br />

Medicare beneficiaries age =67 years who initiated chronic dialysis between 1/1/1995 to 12/31/2008.<br />

We examined mortality and its association with inpatient initiation <strong>of</strong> chronic dialysis and intensity <strong>of</strong><br />

care received during the index hospitalization, including duration <strong>of</strong> hospital stay, intensive care unit<br />

(ICU) admission and receipt <strong>of</strong> an intensive procedure (mechanical ventilation, cardiopulmonary<br />

resuscitation and feeding tube placement).<br />

Results: Overall, 53.9% <strong>of</strong> patients initiated chronic dialysis as an inpatient. Of these patients, 45.8%<br />

were admitted to the ICU and 7.4% had received at least one intensive procedure. Average length <strong>of</strong><br />

stay during the index hospitalization was 14.8 days (median 11 days). Mean survival was 1.8 years (1.1<br />

median) in patients who initiated dialysis as an inpatient as compared with 2.2 years (median 1.5 years)<br />

in those who initiated dialysis as an outpatient (p84 years (61.4% v. 40.6%; HR 1.79, 95CI 1.75-83), male (48.3% v. 46.5%; HR 1.02 (1.01-1.04),<br />

had developed ESRD as a result <strong>of</strong> non-resolving tubular necrosis (62.8% v. 47.8%; HR 1.25, 95%CI 1.20-<br />

1.30), had >3 comorbidities (48.7% v. 40.7%; HR 1.25, 95%CI 1.23-1.27), had no prior nephrology care<br />

(69.8% v. 60.9%; HR 1.14, 95%CI 1.12-1.21), had catheter access at initiation <strong>of</strong> dialysis (66.8% v. 53.6%;<br />

HR 1.34, 95%CI 1.28-1.40), and had died <strong>of</strong> cardiovascular causes (47.9% v. 47.1%; HR 1.07, 95%CI 1.05-<br />

1.09). After adjustment for differences in patient characteristics, one-year mortality was higher in<br />

patients who initiated dialysis during an index hospitalization <strong>of</strong> >2 weeks (55.5% v. 41.6%; HR 1.47,<br />

95%CI 1.44-1.49) and in which they received an intensive procedure (63.3% v. 41.6%; HR 1.78, 95%CI<br />

1.73-1.82).<br />

Conclusion: Inpatient initiation <strong>of</strong> chronic dialysis is very common in older patients. Life expectancy is<br />

extremely limited in this group, particularly in those with advanced age and complicated hospital<br />

courses. Our findings assist healthcare workers in providing anticipatory guidance to patients initiating<br />

chronic dialysis in the inpatient setting.<br />

Pre-Operative Cardiac Variables and Clinical Outcomes in Patients with Bilateral Lung Transplants<br />

Ajay Yadlapati, MD; Jamil Aboulhosn, MD<br />

Introduction: Orthotopic lung transplantation is now widely performed in patients with advanced lung<br />

disease. As part <strong>of</strong> the pre-operative work-up <strong>of</strong> these patients, investigation <strong>of</strong> cardiac function with<br />

echocardiography and catheterization has been long considered the norm. Patients with moderate or<br />

severe ventricular systolic dysfunction are typically excluded from lung transplantation; however, there<br />

is a paucity <strong>of</strong> data regarding the prognostic significance <strong>of</strong> abnormal left ventricular diastolic function.<br />

Methods: We reviewed the characteristics <strong>of</strong> 111 patients who underwent bilateral lung transplant at<br />

UCLA medical center from 2002-2009 in order to evaluate the prognostic significance <strong>of</strong> preoperative<br />

markers <strong>of</strong> diastolic function, including: Invasively measured pulmonary capillary wedge pressure<br />

(PCWP) and echocardiographic variables <strong>of</strong> diastolic dysfunction including mitral A/E>1, E/E’>13 and<br />

A’>E’.<br />

Results: Out <strong>of</strong> 111 patients, 62 were male (56%) and average age was 54.0 (SD = 10.5) years. Clinical<br />

end-points included: All-cause mortality post-transplant, cardiac death post-transplant, length <strong>of</strong><br />

hospitalization post-transplant, and evidence <strong>of</strong> graft dysfunction. Mildly elevated pre-transplant PCWP<br />

(16-20 mmHg) and moderate/severely elevated PCWP (>20 mmHg) were not associated with adverse<br />

clinical events post-transplant (p=0.51 and 0.61, respectively). Traditional echocardiographic doppler<br />

variables <strong>of</strong> abnormal diastolic function, including A’>E’ and A/E ratio>1 did not predict adverse<br />

events. An echocardiographic marker <strong>of</strong> elevated left atrial pressure (E/E’>13) also did not predict<br />

adverse post-transplant events.<br />

Conclusion: Pre-lung transplant invasive and echocardiographic findings <strong>of</strong> elevated left atrial pressure<br />

and abnormal left ventricular diastolic function do not predict adverse post-transplant clinical events.<br />

Ashraf M Al Azzoni, MBBS Nooreen Popat, MD; Lindsay Crab, MD; Jovana Yudin, MD; Mark Soth, MD.<br />

Introduction: Long stays in the ICU are associated with high costs to the health care system, burdens on<br />

patients and their families and, frequently, poorer long term outcomes for patients. Interventions that<br />

reduce length <strong>of</strong> stay in the ICU are, therefore, very important. Critical care response teams (CCRT) have<br />

been widely implemented in hospitals in the last 5 years. This study examines the relationship between<br />

the presence <strong>of</strong> a critical response team and ICU length <strong>of</strong> stay, as well as other patient-important<br />

outcomes.<br />

Methods: A retrospective chart review <strong>of</strong> all unplanned admissions to the ICU at St. Joseph’s Hospital<br />

from January 2005 to December 2009. During this period <strong>of</strong> time, the CCRT team was implemented in<br />

the hospital and therefore patients were classified as pre- and post- CCRT admissions. Multiple variables<br />

were recorded including patient demographics, medical history, pre- and post-ICU MODS scores<br />

(prognostic indicator scores), and length <strong>of</strong> stay in the ICU and hospital as well as mortality.<br />

Results: 629 patients were included. The implementation <strong>of</strong> CCRT teams resulted in a reduction in<br />

mortality during ICU admission in patients who received a CCRT consult (Mean 1.33 vs. 1.49 in post- and<br />

Shared Decision-Making in PSA Testing: The Effect <strong>of</strong> a Mailed Patient Flyer Prior to an Annual Exam<br />

Alison Landrey MD Daniel D. Matlock MD, MPH Laura Andrews, BA Michael Bronsert, MS, PhD Thomas<br />

Denberg MD, PhD<br />

Introduction: Pr<strong>of</strong>essional societies recommend that the decision to screen for prostate cancer involve<br />

a shared discussion between patient and provider. Many men are tested without this discussion.<br />

Prostate cancer screening decision aids increase patient knowledge and participation in PSA testing<br />

decisions under ideal circumstances, but are <strong>of</strong>ten resource-intensive and elaborate. There is a need for<br />

evaluation <strong>of</strong> pragmatic interventions that are low-cost, low-literacy and practical for widespread<br />

distribution.<br />

Methods: We evaluated the effect <strong>of</strong> a mailed low-literacy informational patient flyer about the PSA<br />

test on measures <strong>of</strong> shared decision making (SDM). 303 men aged 50-74 who were scheduled for annual<br />

health maintenance exams in two University <strong>of</strong> Colorado general internal medicine clinics were<br />

randomized to receive the flyer vs. usual care. Primary outcomes included chart documented PSA<br />

screening discussions and PSA testing; secondary outcomes from follow-up patient surveys include<br />

perceived participation in PSA screening decisions, knowledge <strong>of</strong> the PSA test, and flyer acceptability.<br />

Results: Rates <strong>of</strong> chart-documented PSA discussions were low with no difference between the flyer and<br />

control groups (17.7% and 13.6% respectively; p = 0.28). Rates <strong>of</strong> PSA testing were also similar in both<br />

groups (62.5% vs. 58.5%; p = 0.48). Rates <strong>of</strong> patient-reported PSA discussions were higher than the<br />

documented rates but also without differences between the groups (71.8% vs. 62.3%; p = 0.22). The<br />

intervention had no effect in the PSA knowledge scores (3.5/5 vs. 3.3/5, p=0.60). Patients found the flyer<br />

to be highly acceptable.<br />

Conclusion: A mailed low-literacy informational flyer had no effect on rates <strong>of</strong> documented PSA<br />

State University, Detroit Medical Center MI, 3Yale University Sch<br />

Introduction: Background: IDSA guidelines recommend de-escalating antibiotics in health-care<br />

associated pneumonia (HCAP) based on lower respiratory cultures. In the absence <strong>of</strong> lower respiratory<br />

cultures, physicians are sometimes reluctant to discontinue Vancomycin (VANC) that was initiated for<br />

suspected HCAP due to methicillin-resistant Staphylococcus aureus (MRSA). Previous studies have<br />

shown that the combination <strong>of</strong> nasal and throat cultures without growth <strong>of</strong> MRSA has a negative<br />

predictive value <strong>of</strong> 97% for MRSA colonization. We studied the safety <strong>of</strong> discontinuing empiric VANC in<br />

HCAP patients (pts) based on negative nasal and throat MRSA surveillance cultures.<br />

Methods: In a convenience sample <strong>of</strong> pts receiving empiric VANC for suspected MRSA HCAP and in<br />

whom no adequate lower respiratory culture was available, the antimicrobial stewardship (AMS) team<br />

recommended obtaining nasal and throat swabs, which were inoculated onto chromogenic MRSA<br />

selective agar. In pts with both cultures negative for MRSA and a clinical pulmonary infection score<br />

(CPIS) less than 6, the AMS team recommended discontinuing VANC. After discontinuing VANC, charts<br />

were retrospectively reviewed to determine if pts expired or developed culture-proven MRSA<br />

pneumonia within 30 days.<br />

Results: From a total number <strong>of</strong> 55 pts, vancomycin was stopped by day 5 in 43 <strong>of</strong> these based on nasal<br />

and throat swabs negative for MRSA and a low CPIS. On the day VANC was discontinued in these 43 pts,<br />

the CPIS was: 0 (6pts), 1 (10pts), 2 (12pts), 3(10pts), 4(5pts). None <strong>of</strong> the pts developed confirmed MRSA<br />

pneumonia during the rest <strong>of</strong> their hospital stay, none was readmitted with a MRSA pneumonia, or<br />

expired secondary to MRSA pneumonia. One pt was readmitted with pneumonia <strong>of</strong> unknown etiology<br />

and was treated with piperacillin-tazobactam plus VANC. One patient who was readmitted for other<br />

reasons expired, and an autopsy showed no evidence <strong>of</strong> pneumonia.<br />

Conclusion: These preliminary data suggest that in the absence <strong>of</strong> a good lower respiratory culture, it is<br />

safe to de-escalate empiric VANC in patients with suspected MRSA HCAP who have both nasal and<br />

throat MRSA swab cultures negative and a low CPIS. Further evaluation <strong>of</strong> this strategy appears<br />

warranted.<br />

MELD Score Predicts Mortality in Cirrhotic Patients with Spontaneous Bacterial Peritonitis<br />

Canals M, Munita JM, Contreras J, Cordero V, Alvarez A, Miranda JP, Perez J<br />

Introduction: Spontaneous bacterial peritonitis (SBP) in patients with liver cirrhosis has a high mortality<br />

rate, both on acute and medium term. Thus, developement <strong>of</strong> SBP is one <strong>of</strong> the indications for liver<br />

transplantation. The Model for End-Stage Liver Disease (MELD) score was created as a marker for<br />

transplant need and is one <strong>of</strong> the main tools available to categorize the severity <strong>of</strong> a chronic liver failure.<br />

Our aim was to evaluate the usefulness <strong>of</strong> the MELD as a prognosis score in cirrhotic patients developing<br />

a SBP.<br />

Methods: The clinical charts <strong>of</strong> all patients with liver cirrhosis and a first episode <strong>of</strong> SBP admitted at<br />

Hospital Padre Hurtado between January 2003 and January 2008 were retrospectively reviewed. Clinical,<br />

demographic and microbiological characteristics were obtained. Patients without enough information to<br />

calculate the MELD score were excluded. The statistical analysis was done with SPSS 13.0. T test and Chi-<br />

Square were used for comparison <strong>of</strong> continuous and categorical variables respectively.<br />

Results: 70 patients were included; among them 45 (64%) were men. The mean age was 59.4+/-11.9<br />

years and the most frequent etiology was alcohol (36/70, 51%). The mean MELD score at admission was<br />

21+/-9 and the CHILD-PUGH A/B/C was 1/28/41, respectively. The average length <strong>of</strong> stay was 11 days (1-<br />

41). An etiologic agent was obtained on 18/70 (26%) <strong>of</strong> cases, <strong>of</strong> which 12/70 (17%) had a positive ascitic<br />

fluid culture and 8/44 (18%) had positive blood cultures. The most frequent organism recovered was E.<br />

standards as the nationally utilized Yale Office-Based Medicine Curriculum, the course focused on<br />

DNI/not DNR patients, reversibility <strong>of</strong> code status, and futility <strong>of</strong> care. The exact Mcnemar test was used<br />

to evaluate changes in responses.<br />

Results:Of 44 surveys, in DNR patients with cardiopulmonary arrest in which no interventions should be<br />

performed, a number <strong>of</strong> participants would provide chest compression (before=9%, after=7%),<br />

defibrillation (before=7%, after=7%), epinephrine (before=32%, after=25%), antiarrhythmics<br />

(before=50%, after=32%), bicarbonate (before=61%, after=48%), manual lung inflation (before=48%,<br />

after=59%), and intubation (before=59%, after=50%). In DNI patients, a number <strong>of</strong> participants failed to<br />

<strong>of</strong>fer manual lung inflation (before=64%, after=86%) and non-invasive positive pressure ventilation<br />

(before=91%, after=93%).<br />

After the course, participants were 9 times more likely to correctly forego antiarrhythmics in coding DNR<br />

patients (p=0.022), and 11 times more likely to correctly <strong>of</strong>fer manual lung inflation in DNI patients<br />

(p=0.006). When asked if participants possess adequate understanding <strong>of</strong> DNR/DNI on a scale <strong>of</strong> one<br />

(disagree) to five (agree), there was a 0.93 point increase after the course (before=3.26, after=4.19,<br />

p=0.000). While 7% <strong>of</strong> the participants feel neutral, 93% would recommend the course to others.<br />

Conclusion: Surveys showed that many participants would provide contraindicated interventions to DNR<br />

patients while failing to <strong>of</strong>fer appropriate intervention to DNI patients. After the course, more<br />

participants reported having an adequate understanding <strong>of</strong> code status. A significant number correctly<br />

withheld antiarrhythmics in coding DNR patients and appropriately <strong>of</strong>fered manual lung inflation to DNI<br />

patients. Our study showed that physicians in training may benefit from education on code status,<br />

particularly case-based learning which may improve their understanding <strong>of</strong> DNR/DNI and the quality <strong>of</strong><br />

end-<strong>of</strong>-life discussion.<br />

Introduction: Current guidelines for the evaluation <strong>of</strong> aortic stenosis (AS) are based on risk benefit<br />

assessments conducted over a decade ago. Several recent studies show sizable differences between<br />

echocardiogram and cardiac catheterization lab measurements <strong>of</strong> the aortic valve area (AVA). In our<br />

recent practice, dyssynchrony between echocardiography-derived and catheterization-derived values<br />

has been noticed, such that decision-to-surgery is altered. Using latest available high quality techniques,<br />

we examined the correlation between echocardiography and catheterization-determined AVA at our<br />

institution.<br />

Methods: We performed sequential retrospective review <strong>of</strong> patients aged 40-90 years with suspected<br />

AS by echo (n=42) who underwent right and left heart catheterization during 2008 to 2011. Matching<br />

echocardiograms within 3 months <strong>of</strong> catheterization were reviewed and patients with a diagnosis <strong>of</strong><br />

“severe” or “critical” aortic stenosis per echocardiogram were included. Patients without precatheterization<br />

echocardiograms were excluded. Catheterizations were conducted by two<br />

interventional cardiologists in an academic community hospital. Valve measurements were derived from<br />

directly measured pressure gradients via left ventricular pressure wire (St. Jude) and ascending aorta<br />

catheter; this is in contrast to previous studies which have utilized variations <strong>of</strong> the “pull-back” method<br />

with diagnostic catheters. Pre-catheterization 2D trans-thoracic echocardiograms were from various<br />

institutions, obtained by a wide variety <strong>of</strong> echocardiography technicians, and read by 15 certified<br />

cardiologists. Original echocardiogram films were independently reviewed by the investigators to assess<br />

the quality <strong>of</strong> community-based readings.<br />

Results: Catheterization changed assessment <strong>of</strong> AVA severity by more than 0.3cm 2 in 33% and by more<br />

than 0.5cm 2 in 12% <strong>of</strong> patients studied. These changes in AVA values were sufficient to cross over or<br />

Is a Mandatory Geriatric Home Visit Acceptable to Students?<br />

Stephen Koplin, MD, Walter Reed National Military Medical Center, Bethesda, MD (Associate) Second<br />

Author: Gerald Denton, MD, MPH, Uniformed Services <strong>of</strong> the Health Sciences, Bethesda, MD (Fellow)<br />

Introduction: Geriatric-specific education during medical school is an important aspect <strong>of</strong> preparing<br />

medical school graduates for an increasingly elderly population. One method found to be effective is<br />

the Geriatric Home Visit (GHV), which attempts to <strong>of</strong>fer medical students the unique perspective <strong>of</strong><br />

interviewing geriatric patient in the setting <strong>of</strong> their daily life. This study aimed to determine whether a<br />

mandatory GHV during third year medical student’s education improved medical student’s attitudes and<br />

abilities towards geriatric care. Outcomes <strong>of</strong> this study will be used to guide further implementation <strong>of</strong><br />

GHV at our institution.<br />

Methods:A mixed methods, retrospective trial was designed using exit surveys <strong>of</strong> GHV completed by<br />

third year medical students (n=168) during their third year Internal Medicine clerkship at the Uniformed<br />

Services University <strong>of</strong> Health Sciences (USUHS) in Bethesda, MD during the 2008-2009 academic<br />

year. The program was designed at USUHS and were completed at 7 different military hospitals around<br />

the US. All third year medical students were instructed to independently identify and contact an<br />

inpatient or outpatient geriatric patient, conduct a home visit, accompanied by a fellow student,<br />

complete a geriatric assessment and a paper describing their experiences. The exit surveys included<br />

Likert scales and comments sections. Likert scales were analyzed using mean responses and proportion<br />

<strong>of</strong> responses above and below the neutral point. Comments were grouped into themes using the<br />

constant comparative method.<br />

Results: All third year medical students were required to complete a GHV, 137 (<strong>of</strong> 168) had a survey<br />

available for review (81.5%). 98% <strong>of</strong> the students reported feeling safe during the visit. 56% <strong>of</strong> students<br />

felt that the GHV helped them learn and improve geriatric assessment techniques. 59% felt that the<br />

GHV impacted the way they view geriatric patients. 77% <strong>of</strong> the students reported being adequately<br />

prepared and 82% and 85% felt supported by their ward or clinic attendings and small group preceptor,<br />

respectively. 32% <strong>of</strong> students had difficulty identifying geriatric patients.<br />

Conclusion: Based on exit surveys, a mandatory GHV during the Internal Medicine rotation changed the<br />

attitudes <strong>of</strong> third year medical students towards geriatric patients and helped them improve their<br />

utilization <strong>of</strong> geriatric assessments. Mandatory GHV in this setting may be a useful tool in improving<br />

knowledge and attitudes in geriatric care. Knowlege <strong>of</strong> students reactions to mandatory GHV will help<br />

guide future development <strong>of</strong> geriatric medical care education.<br />

Objective Laboratory Targets in Treatment <strong>of</strong> Patients Hospitalized for Heart Failure<br />

Marlow B. Hernandez, DO, MPH Elsy V. Navas, MD Craig R. Asher, MD Randall Schwartz, MD Victor<br />

Totfalusi, DO Ivan Buitrago, MD Ankush Lahoti, MD Gian M. Novaro, MD<br />

Introduction: In the United States, the estimated prevalence <strong>of</strong> heart failure (HF) approaches 6 million<br />

individuals, and the direct and indirect costs <strong>of</strong> HF approaches $40 billion. Despite advances in the<br />

medical management <strong>of</strong> HF, HF remains the leading cause <strong>of</strong> hospitalizations and readmissions in the<br />

United States. Within 3 months <strong>of</strong> hospitalization, there is a national 30% readmission rate, and 10%<br />

mortality rate. Therefore, there is currently a focus to stratify high-risk patients with clinical indicators in<br />

order to decrease in-hospital mortality and readmission rates.<br />

BNP guided therapy has been shown to decrease outpatient HF related healthcare cost by nearly 25%<br />

(totaling over $5,000 per patient, per year). The purpose <strong>of</strong> our study is to identify objective laboratory<br />

targets that reduce re-admission rates.<br />

Methods: Data for patients that were admitted to Cleveland Clinic Florida with principal diagnoses <strong>of</strong><br />

heart failure from April 1, 2010 to December 31, 2010 was retrospectively obtained via chart review. A<br />

total <strong>of</strong> 233 patients were analyzed. Using a multivariable logistic regression analysis, the factors were<br />

examined for statistical significance in an attempt to extract predictive factors associated with<br />

readmission or mortality for heart failure in the 6 month period following the initial hospitalization.<br />

Thirty day HF readmission was set as the study’s primary end point. Factors strongly linked to<br />

readmission or mortality where examined using chi-squares and ROC curves, as applicable.<br />

Results: The results suggest the majority <strong>of</strong> HF readmissions occur within the first 30 days <strong>of</strong> discharge<br />

(median 9.5d, 95% CI [5d-14d]). BiV Pacemaker, ICD, higher BMI, higher sodium levels, negative fluid<br />

balance, reduction in NT-proBNP, and normal systolic BP seem to be protective against HF readmission.<br />

ROC curve analysis shows that fluid reduction <strong>of</strong> greater than 1.84L gives an OR <strong>of</strong> 0.36 for 30d HF<br />

readmission. Similarly, a Na + level <strong>of</strong> greater than 136 and a NT-proBNP reduction <strong>of</strong> greater than<br />

23% at discharge are markers <strong>of</strong> favorable HF prognosis at 30 days, with ORs <strong>of</strong> 0.40 (p < 0.05) and 0.10<br />

(Haldane’s Estimator, p < 0.05) respectively. Meeting two or more <strong>of</strong> the above (lab) criteria goals (Fluid,<br />

Na + , NT-proBNP) results in OR <strong>of</strong> 0.06 for HF readmission compared to patients who did not meet two <strong>of</strong><br />

the goals.<br />

Conclusion: The results <strong>of</strong> this pilot study suggest that there are optimum levels <strong>of</strong> fluid reduction, NTproBNP<br />

reduction, and sodium at discharge, in order to achieve more favorable clinical outcomes. If<br />

clinical dispositions for acute HF inpatients are based on objective laboratory data, it may standardize<br />

what is currently a highly variable clinical decision making process. Apart from the clinical benefits, this<br />

approach may have significant economic benefits. The results <strong>of</strong> this study suggest that combining<br />

biomarkers with other clinically significant inpatient variables may improve short-term HF outcomes.<br />

Prophylactic Use <strong>of</strong> Macrolide Antibiotics for the Prevention <strong>of</strong> Exacerbations in Patients with Chronic<br />

Obstructive Pulmonary Disease: A Meta-Analysis<br />

Abubakr Chaudhry MD. All Authors: Elie Donath MD MPH, Leonel Hernandez-Aya MD<br />

Introduction: Chronic Obstructive Pulmonary Disease (COPD) affects over 12 million <strong>American</strong>s, among<br />

which 20-30% have exacerbations annually leading to hospitalization. Multiple studies have evaluated<br />

the use <strong>of</strong> prophylactic macrolides for the prevention <strong>of</strong> COPD exacerbations with variable results. The<br />

purpose <strong>of</strong> our study was to conduct a meta-analysis and develop conclusive evidence regarding the<br />

prophylactic use <strong>of</strong> macrolides in the prevention <strong>of</strong> COPD exacerbations.<br />

Methods: EMBASE, Medline and CENTRAL databases were searched for all controlled trials in which any<br />

type <strong>of</strong> macrolide was compared to placebo for prevention <strong>of</strong> COPD exacerbations. A total <strong>of</strong> 247<br />

studies were identified, <strong>of</strong> which 8 trials met the inclusion criteria for the study. The primary outcome<br />

was the relative risk <strong>of</strong> COPD exacerbation. Potentially relevant information concerning study design,<br />

type <strong>of</strong> intervention, study population, methods <strong>of</strong> follow-up, outcomes, and methodology quality were<br />

extracted.<br />

Results: Using the random effects-model, the pooled estimate for incidence <strong>of</strong> COPD exacerbations<br />

showed a 34% reduced risk (RR=.66, 95% CI: 0.54-0.0.81, p=0.001, I2=71%) <strong>of</strong> exacerbations among<br />

patients taking prophylactic macrolides. The high I-squared value suggests significant heterogeneity<br />

among the different outcomes. Further subgroup analyses revealed that COPD severity was an<br />

important variable in determining effect size. Three <strong>of</strong> the trials included patients with mild/moderate<br />

COPD and the other five trials included patients with only severe/very severe COPD. We found that<br />

among studies that included patients with mild/moderate COPD there was a 22% reduced risk (RR=.78,<br />

95% CI: 0.65-0.0.94, p=0.02, I2=63%) <strong>of</strong> exacerbations in patients taking macrolides. Among studies<br />

including patients with severe/very severe COPD, there was a 42% reduced risk (RR=.58, 95% CI: 0.47-<br />

0.0.72, p=0.01, I2=22%) <strong>of</strong> COPD exacerbations in patients taking macrolides. Of note, the I-squared was<br />

reduced significantly through this approach. Meta-regression was employed to assess several additional<br />

variables <strong>of</strong> interest but no definitive trends were identified. There was no consistent systematic bias<br />

among the selected studies.<br />

Conclusion: Administration <strong>of</strong> prophylactic macrolides to patients with COPD may be an effective<br />

approach to decrease the incidence <strong>of</strong> COPD exacerbations. Additionally, the subgroup analysis revealed<br />

that prophylactic macrolides may be more effective at reducing exacerbations in patients with<br />

severe/very severe COPD compared to patients with mild/moderate COPD. There are limitations to this<br />

study including the large degree <strong>of</strong> heterogeneity, the limited number <strong>of</strong> randomized controlled studies<br />

identified and the inability to effectively capture the adverse effects associated with this treatment. We<br />

urge investigators to consider undertaking more trials to assess this phenomenon further.<br />

Does Implementing a Standardized Hand<strong>of</strong>f Process Improve Adherence to Best Practices and Patient<br />

Outcomes on the General Medical wards?<br />

Elizabeth Marsicano, MD Sharad Virmani MD, Elie Donath MD,MPH<br />

Introduction: The ACGME’s mandate regarding new resident work hours has been met with a necessary<br />

increase in the amount <strong>of</strong> transition <strong>of</strong> care points. This increase has led to concerns that poor quality -<br />

hand<strong>of</strong>fs can lead to increased risk to patients. The Joint Commission addressed these concerns in 2008<br />

suggesting a standardized approach to transition <strong>of</strong> care was needed. The aim <strong>of</strong> this study was to<br />

assess the effectiveness <strong>of</strong> integrating a standardized hand<strong>of</strong>f system on self-reported adherence to<br />

accepted best practices and patient outcomes on the general medical teaching service.<br />

Methods: A voluntary survey, <strong>of</strong> 24 questions, was distributed to internal medicine residents in June<br />

2011 to assess quality <strong>of</strong> their hand<strong>of</strong>fs and its perceived effects on patient care (49 eligible residents,<br />

response rate 59%). In July 2011 an educational conference emphasizing the importance <strong>of</strong> quality<br />

hand<strong>of</strong>fs, and introducing a standardized system for hand<strong>of</strong>fs on the general medical floors was<br />

held. The survey was repeated in November 2011 (64 eligible residents, response rate 43%). A Likert<br />

scale was used to evaluate characteristics contributing to effective hand<strong>of</strong>fs. Survey responses pre and<br />

post intervention were compared using ordinal logistic regression and adjusting for resident year (PGY1-<br />

Cerebrospinal Fluid Flow Cytometric Immunophenotyping in Adult Patients with Newly Diagnosed<br />

Acute Lymphoblastic Leukemia/Lymphoblastic Lymphoma: Added Value?<br />

Department <strong>of</strong> Pathology and Laboratory Medicine, Emory University. Hanna Jean Khoury, MD,<br />

Department <strong>of</strong> Hematology and Medical Oncology, the Winship C<br />

Introduction: Cerebrospinal fluid (CSF) involvement by leukemic blasts occurs in fewer than 10 % <strong>of</strong><br />

adult patients with newly diagnosed acute lymphoblastic leukemia/lymphoma (ALL). Leukemic<br />

meningitis is suspected when abnormal CSF protein and glucose are found. Confirmatory testing<br />

includes red and white blood cell (WBC) counts and WBC differential, cytologic evaluation and flow<br />

cytometric immunophenotyping (FCI). To our knowledge, no study has addressed the additional benefits<br />

provided by CSF FCI as compared to other means <strong>of</strong> confirmatory testing in newly diagnosed patients<br />

with ALL.<br />

Methods: Patient demographics, disease characteristics, CSF and bone marrow findings, systemic and IT<br />

chemotherapy treatments, complications, remission, relapse, and survival <strong>of</strong> patients with newly<br />

diagnosed ALL were captured on study specific case report forms. CSF was classified as “positive” or<br />

“negative” based on the presence or not <strong>of</strong> abnormal protein, glucose, and cytology. Statistics were<br />

descriptive, performed using SPSS 16.0. The results are reported as a proportion.<br />

Results: Between 11/2007 and 8/2011, 80 patients with newly diagnosed ALL were referred to the<br />

Winship Cancer Institute <strong>of</strong> Emory University, all <strong>of</strong> which had CSF analysis available. Throughout the<br />

treatment <strong>of</strong> these 80 patients, a total <strong>of</strong> 810 samples were analyzed using conventional methods, and<br />

24 (3%) were positive and 786 (97%) were negative. Flow cytometric analyses were performed on<br />

179/786 (23%) negative samples and 13/24 (54%) positive samples. FCI showed no aberrant cells in any<br />

<strong>of</strong> the 179 negative samples, whereas leukemic cells were detected by in 9/13 (69%) cytologicallypositive<br />

samples. One sample was positive using conventional methods, but FCI showed no aberrant<br />

cells. The patient was treated as CSF negative.<br />

Conclusion: In this study <strong>of</strong> 810 CSF samples from 80 patients with newly diagnosed ALL, FCI was found<br />

to be <strong>of</strong> no additional utility in patients without evidence <strong>of</strong> leukemic involvement by standard criteria<br />

<strong>of</strong> glucose and protein measurements and cell counts, as well as cytologic evaluation. One patient in<br />

whom cytologic examination was reportedly positive for involvement by ALL were found to be negative<br />

by FCI, and was ultimately re-classified as negative. In light <strong>of</strong> these findings, we suggest that FCI be<br />

performed as confirmatory testing only in patients with high pre-test probability based on standard<br />

criteria.<br />

Rapid Recovery <strong>of</strong> LDL after Apheresis in Patients with Familial Hypercholesterolemia: A Need for<br />

More Frequent Treatment?<br />

*Emory University School <strong>of</strong> Medicine, Atlanta GA. †Atlanta VA Medical Center, Atlanta GA.<br />

Introduction: Familial hypercholesterolemia (FH) is a rare genetic disease <strong>of</strong> accelerated atherosclerosis<br />

due to poor plasma LDL clearance. LDL apheresis therapy is considered in patients with FH who have not<br />

achieved lipid goals despite dietary discretion and maximum pharmacotherapy. Apheresis acutely<br />

reduces plasma LDL cholesterol level allowing for improved cardiovascular outcomes in this population.<br />

Current guidelines recommend one treatment every 1 to 2 weeks. The aim <strong>of</strong> this study was to better<br />

characterize the effect <strong>of</strong> apheresis and the recovery kinetics <strong>of</strong> lipid and inflammatory markers postapheresis.<br />

Methods: The INFLAME Study is a pilot observational, case-series clinical intervention study. Patients<br />

with FH on maximum pharmacotherapy undergoing LDL apheresis were identified and nonconsecutively<br />

enrolled. LDL apheresis was performed for each subject according to standard protocol<br />

including treatment <strong>of</strong> 1.5 plasma volumes per person with dextran-sulfate cellulose adsorption<br />

columns (Liposorber LA-15). Plasma levels <strong>of</strong> total cholesterol (TC), LDL, triglycerides (TG), and C-reactive<br />

protein (CRP) were measured pre- and post-apheresis at multiple time points during a 48 hour inpatient<br />

diet-controlled stay.<br />

Results:8 FH patients (7 heterozygous, 1 homozygous; 6 female, 2 male) with a mean age <strong>of</strong> 48 ± 17<br />

years and mean body mass index <strong>of</strong> 28.4 ± 5.2 kg/m 2 were assessed. Cardiovascular demographics <strong>of</strong> the<br />

patients included 4 with prior myocardial infarction, 6 with coronary artery disease, 5 with carotid artery<br />

disease, 5 with hypertension, 1 with an impaired fasting glucose, 3 with obesity, and 8 with a strong<br />

family history <strong>of</strong> premature cardiovascular disease. Mean pre- and post-apheresis levels were: 338 and<br />

126 mg/dL for TC, 257 and 67 mg/dL for LDL, and 2.76 and 1.05 mg/dL for CRP, respectively (p < 0.05,<br />

all). Compared to pre-apheresis levels, mean percent recovery post-apheresis at 12, 24 and 48 hours for:<br />

LDL was 31.1%, 37.5%, and 49.7%; and CRP was 90.5%, 134%, and 120%, respectively.<br />

Conclusion: Our data show that LDL apheresis not only significantly decreased plasma LDL cholesterol<br />

level, but also dramatically reduced plasma CRP. The reduction in both lipid and inflammatory<br />

biomarkers suggests that the therapeutic effect <strong>of</strong> LDL apheresis likely goes beyond lipid pathways. Of<br />

note, the recovery rate <strong>of</strong> LDL was rapid, returning to 50% <strong>of</strong> pre-treatment level by day 2. Given the<br />

linear rate <strong>of</strong> LDL recovery, LDL would be expected to rebound to pre-treatment levels by day 4,<br />

suggesting that a shorter treatment interval may provide further benefit in this population.<br />

characteristics, clinical outcomes, and pharmacologic monitoring. Primary outcome measures included<br />

time to clinical stability, in-hospital mortality, and development <strong>of</strong> VAN associated nephrotoxicity.<br />

Results: Baseline characteristics <strong>of</strong> both groups were similar. In-hospital morality, and development <strong>of</strong><br />

Methods: A total <strong>of</strong> 185 cases were reviewed by two physicians. The primary reviewer was responsible<br />

for data collection including subjective complaints, presence <strong>of</strong> a Foley catheter, clinical findings,<br />

laboratory data, and whether the treating clinician diagnosed and treated a UTI. The secondary reviewer<br />

applied the National Healthcare Safety Network (NHSN) criteria specified by the Centers for Disease<br />

Control and Prevention for nosocomial UTI to the patient data to determine if the clinical decision made<br />

by the treating clinician followed published guidelines for diagnosis <strong>of</strong> a healthcare-associated UTI. If<br />

NHSN criteria were not met, then the patient was not classified as having a UTI by the secondary<br />

reviewer. All data analysis was completed by a statician.<br />

Results: The proportion <strong>of</strong> patients with colony counts 100,000 CFU/mL are 12.93 times more likely to be classified as having a UTI by the primary<br />

reviewer than patients with colony counts

Gaurav Jain, MD Trinadha Pilla, MD Jacob Thomas, MD Edgard Cumpa, MD Andrew Varney, MD.<br />

Introduction: The United States Preventive Services Task Force recommends one time screening for<br />

Abdominal Aortic Aneurysm (AAA) by ultrasound in men aged 65 to 75 year who have ever smoked. We<br />

assessed the quality <strong>of</strong> the AAA screening in our General Internal Medicine (GIM) clinics before and after<br />

the introduction <strong>of</strong> a point-<strong>of</strong>-care electronic health record (EHR) reminder.<br />

Methods: Authors conducted a chart review to assess the baseline AAA screening rate at the GIM<br />

outpatient clinics. An intervention was implemented to incorporate a point-<strong>of</strong>-care EHR screening<br />

reminder for all eligible patient visits. Authors reviewed charts to assess screening rates after the<br />

intervention. The total study period was nine months. Data were collected and analyzed from preintervention<br />

and post-intervention periods <strong>of</strong> four months each.<br />

Results: Pre-intervention, 157 patients met the criteria <strong>of</strong> screening but only 14 (8.9%) underwent<br />

screening. Post-intervention, 108 (54.3%) met the criteria for screening and 25 (23.1%) underwent<br />

screening. The increase in AAA screening rate was significant (P = 0.0023).<br />

Conclusion: A low cost and simple point-<strong>of</strong>-care EHR reminder was helpful to increase the rate <strong>of</strong> AAA<br />

screening.<br />

unexpected antibodies. Most <strong>of</strong> these unexpected antibodies are IgM, also known as nuisance<br />

antibodies. They are thought not to have much clinical significance. A positive antibody screen can<br />

sometimes be associated with inconclusive antibody identification (ABID), defined as test reactive for<br />

gel-screen (which is a two-cell screen) with no defined pattern on ABID panel. <strong>American</strong> Association <strong>of</strong><br />

Blood Banking states that if an antibody screen is positive, an attempt should be made to identify the<br />

antibody and cross-match for the same along with ABO-Rh. However, there is no literature regarding<br />

clinical implications <strong>of</strong> the scenario where the antibody screen is positive but the ABID is inconclusive.<br />

This study was undertaken to review this specific scenario.<br />

Methods: All patients who had antibody screen performed with inconclusive ABID during January-2005<br />

to December-2010 were identified from our blood-bank database and retrospectively screened for<br />

clinical diagnosis, antibody screen, ABID, repeat screen, blood transfusions, rise in hemoglobin per unit<br />

<strong>of</strong> packed red blood cells and occurrence <strong>of</strong> transfusion-reactions. Patients with active blood loss at the<br />

time <strong>of</strong> screen, hemolysis or a positive antibody identified in previous screening were excluded. The<br />

control group comprised <strong>of</strong> patients with definite positive antibody screen with an identifiable antibody,<br />

during the same period. In our institution, the patients who have positive antibody screen get crossmatched<br />

by gel-technology. We use Reagent Red Blood Cells 0.8% Selectogen for two-cell screen and<br />

Reagent Red Blood Cells 0.8% Resolve panel A Antigram Antigen Pr<strong>of</strong>ile (Ortho Clinical Diagnostics) for<br />

defining pattern <strong>of</strong> antibodies.<br />

Results: A total <strong>of</strong> 149 patients and 150 controls were included in the study based on above criteria. 69<br />

(46.3%) patients from the study group had a repeat antibody screen done at a later date revealing<br />

definite identifiable antibody in 16 (23%), negative screen in 33 (48%) and inconclusive again in 29%. 38<br />

patients and 37 controls received transfusions. The average rise in hemoglobin per unit <strong>of</strong> red blood cell<br />

was 1.1 g/dL in both groups. One patient in the study group had transfusion-reaction compared to none<br />

in the control group. The transfusion reaction was a non-lethal delayed hemolytic reaction in a patient<br />

who was subsequently identified to have “Jka” antibody at a later date. This equates to 0.7% <strong>of</strong> all<br />

patients with inconclusive screen and 6% <strong>of</strong> patients who would have an antibody identified on<br />

subsequent testing.<br />

Conclusion: Patients with inconclusive ABID on positive antibody screen are usually ignored as having<br />

not much clinical significance. Our study indicates that although transfusion appears relatively safe in<br />

such patients, they can rarely have transfusion reactions, likely due to yet unidentified antibodies. About<br />

a quarter <strong>of</strong> patients will have an antibody identified on subsequent testing. Hence, all patients with<br />

inconclusive ABID screen should be tested again, to identify if an antibody is present, in order to avoid<br />

any untoward reactions.<br />

Are we Practicing Evidence-Based Medicine? Chlorthalidone (CTD) vs. Hydrochlorothiazide (HCTZ) to<br />

Reduce Blood Pressure (BP) and Cardiovascular Events (CVE): A Systematic Review<br />

Kiran Narreddy, MD Co-Author: Jean Holley, MD<br />

Introduction: Hypertension affects roughly one in four <strong>American</strong>s. Guidelines from the Joint National<br />

Committee and Veteran’s Health Administration/ Department <strong>of</strong> Defense Clinical Practice Guideline on<br />

the Management <strong>of</strong> Hypertension recommend thiazide diuretics as first line agents to treat<br />

hypertension. None <strong>of</strong> these guidelines designate a preferred thiazide. Landmark clinical trials like<br />

Antihypertensive and Lipid- Lowering Treatment to Prevent Heart Attack Trial (ALLHAT), Hypertension<br />

Detection Follow-Up Program (HDFP), and Systolic Hypertension in the Elderly Program (SHEP) used<br />

CTD- based thiazide regimens. In all these trials, CTD reduced CVE. Yet HCTZ is the most commonly<br />

prescribed thiazide for treating hypertension. Objective: To determine if the literature shows CTD is<br />

more effective than HCTZ in reducing BP and CVE.<br />

Methods: A literature search in PUBMED and EMBASE (that also includes MEDLINE) using the terms “<br />

Chlorthalidone” AND “Hydrochlorothiazide” from 1958 to <strong>2012</strong> identified 505 articles. 21 relevant<br />

articles were reviewed according to our objective. Only 3 articles directly compared outcomes between<br />

CTD and HCTZ. Two were retrospective observational cohort analyses from Multiple Risk Factor<br />

Intervention Trial (MRFIT trial). The third was a small-randomized controlled trial <strong>of</strong> 8 weeks duration.<br />

Results: MRFIT was a cardiovascular primary prevention trial, which enrolled 12,866 men aged 35 to 57<br />

years. Systolic BP and CVE were measured yearly. CVE were lower in those on CTD (adjusted hazard<br />

Trellis thrombectomy - A Novel Endovascular treatment <strong>of</strong> Acute Deep Vein Thrombosis<br />

Vijaya Sivalingam Ramalingam, MD Other Authors: Ramapriya Sinnakirouchenan, MD, Gary Kerber, MD<br />

Introduction: Deep vein thrombosis (DVT) is a major clinical problem in the United States affecting<br />

500,000 to 2 million people per year. Post thrombotic syndrome (PTS) affects at least 30% <strong>of</strong> them and<br />

has an adverse impact on quality <strong>of</strong> life. Aggressive endovascular treatment <strong>of</strong> acute DVT has been<br />

shown to decrease the incidence <strong>of</strong> PTS. We report the successful utilization <strong>of</strong> Trellis thrombectomy, an<br />

isolated pharmacomechanical thrombolysis (iPMT) method, in reducing thrombus load.<br />

Methods: Retrospective analysis was performed <strong>of</strong> all consecutive patients (n=8) treated with Trellis<br />

thrombectomy from August 2009 to October 2010. We identified 3 patients with acute DVT, 4 patients<br />

with acute on chronic DVT and 1 patient with AV graft thrombus. Concurrent therapies included<br />

retrievable inferior vena cava filter insertion (n=7) and angioplasty and stenting (n=6). The primary<br />

endpoint was restoration <strong>of</strong> rapid inline venous flow. The secondary endpoint was thrombus clearance.<br />

Results: Restoration <strong>of</strong> rapid inline venous flow was achieved in all cases. Thrombus removal was<br />

greater than 95% in all patients without pre-existing thrombus (n=4). A follow up duplex ultrasound at 6months<br />

demonstrated patent venous system in them. In patients with acute on chronic DVT (n=4),<br />

thrombus removal was 50%-95% in 2 patients and less than 50% in 2 other patients. There were no<br />

major complications.<br />

Conclusion: Aggressive endovascular treatment <strong>of</strong> acute DVT has been shown to reduce the thrombus<br />

load, eliminate venous obstruction, improve valvular function, decrease the incidence <strong>of</strong> PTS and<br />

thereby improve quality <strong>of</strong> life. Both systemic and catheter directed thrombolysis have significant<br />

bleeding complications and prolonged hospital stay. iPMT using the Trellis device is a useful alternative.<br />

It involves passing a double balloon catheter through the clot, positioned such that a balloon is inflated<br />

on either side <strong>of</strong> the clot. This limits the systemic release <strong>of</strong> the thrombolytic drug and allows for use <strong>of</strong><br />

a smaller dose. Further mechanical oscillation <strong>of</strong> the catheter ensures complete lysis <strong>of</strong> the clot which is<br />

then aspirated. Our study demonstrates the Trellis system to be a safe and feasible single-session PMT<br />

method for the treatment <strong>of</strong> acute DVT. It is also found to be more beneficial in patients with acute<br />

thrombus than in patients with acute on chronic thrombus.<br />

Clinical and Genetic Predictors <strong>of</strong> Weight Gain in Patients Diagnosed With Breast Cancer<br />

Sangeetha Reddy, Maureen Sadim, Virginia Kaklamani<br />

Introduction: In contrast to other cancer patients, many patients diagnosed with breast cancer gain<br />

weight after diagnosis. In addition to decreased quality <strong>of</strong> life, obese patients have decreased response<br />

to chemotherapy, increased cancer recurrence, and higher all-cause mortality. Our study was designed<br />

to identify factors that contribute to weight gain in patients diagnosed with breast cancer.<br />

Methods: A total <strong>of</strong> 565 patients diagnosed with breast cancer were prospectively and retrospectively<br />

recruited. Chart review was conducted to obtain weights and BMIs over an 18 month period from<br />

diagnosis. The medical record was searched for tumor characteristics (ER/PR/HER2 status, grade,<br />

presence <strong>of</strong> LN metastases, stage), demographics (age, race), clinical factors (menopausal status), and<br />

treatment regimens (chemotherapy use and type, hormone therapy use and type, radiation therapy<br />

use). Blood samples were genotyped for polymorphisms in FTO (fat mass and obesity-associated<br />

protein) and the adiponectin pathway, two pathways found to be associated with obesity and breast<br />

cancer risk.<br />

Results: The average age <strong>of</strong> patients at diagnosis was 51 years (range 26-87). The percentage <strong>of</strong> patients<br />

gaining weight after diagnosis was 53.0% at 3-6 month follow-up, 60.2% at 1 year, and 68.1% at 18<br />

months. In univariate analysis, the following variables were found to be significant for increase in BMI:<br />

Endothelial Derived Cardioprotection Is Abolished By Hyperglycemia<br />

Thorsten M. Leucker, MD, Phillip F. Pratt Jr., PhD, David C. Warltier, MD, PhD, Judy R. Kersten, MD and<br />

Steven P. Jones, PhD<br />

Introduction: Previous experimental findings elucidating mechanisms <strong>of</strong> endogenous cardioprotection<br />

have focused predominately on the cardiomyocyte (CM) and little attention has been paid to the<br />

specific contribution <strong>of</strong> endothelial cells (EC) to CM protection. CM are surrounded by a complex<br />

network <strong>of</strong> capillaries and depend on EC not only for nutritive function, but are also influenced by ECderived<br />

paracrine factors (e.g. NO) that may promote CM survival. Conversely, endothelial dysfunction<br />

presents during various disease states such as diabetes, hypercholesterolemia or hypertension may<br />

disrupt favorable EC-CM interactions.<br />

Methods: EC were cocultured with CM at different ratios (1:3, 1:6, 1:12) and subjected to 120 min <strong>of</strong><br />

hypoxia followed by 120 min <strong>of</strong> reoxygenation (H/R). Equal numbers <strong>of</strong> CM were used in all<br />

experimental groups. EC-CM ratio <strong>of</strong> 1:3 showed the most pronounced CM protection (LDH release<br />

coculture 21.7±0.9 fold change to normoxic control vs. 82.4±3.8 in CM alone). EC alone, subject to H/R<br />

did not significantly contribute to LDH release. EC-derived cardioprotection was abolished by 1 mM<br />

LNAME (85±9.5% <strong>of</strong> CM alone) or by prior incubation <strong>of</strong> EC in hyperglycemic media (81±1.7% <strong>of</strong> CM<br />

alone). Interestingly, the addition <strong>of</strong> 50 mM sepiapterine, a substrate for tetrahydrobiopterin (BH4)<br />

synthesis, reversed (25±2.3% <strong>of</strong> CM alone) the detrimental effect <strong>of</strong> hyperglycemia and restored the<br />

protective properties <strong>of</strong> EC in coculture.<br />

Results: Our data demonstrates the importance <strong>of</strong> EC-derived factors in protection <strong>of</strong> CM against<br />

ischemia reperfusion (I/R) injury. The observation that protection was attenuated by NOS inhibition or<br />

high glucose supports the concept that EC derived NO is a key element involved in cardioprotection.<br />

Diabetes and hyperglycemia have been shown to decrease bioavailable NO and the restoration <strong>of</strong> ECderived<br />

CM protection with sepiapterine suggests that cardioprotection is also BH4-dependent.<br />

Decreases in BH4 contribute to EC dysfunction in diabetes, whereas, BH4 supplementation decreases<br />

ROS production and restores EC function induced by acute hyperglycemia and diabetes.<br />

Conclusion: Elucidating the role <strong>of</strong> EC-CM interactions during I/R injury suggests new therapeutic<br />

approaches to the treatment <strong>of</strong> patients with diabetes and dysfunctional endothelium.<br />

Introduction: Heat shock proteins (HSPs) are intracellular polypeptides which are induced in response to<br />

a variety <strong>of</strong> stimuli, and act as molecular chaperones carrying out several housekeeping functions in the<br />

cell. HSP70 is overexpressed in human pancreatic cancer cell lines. The study was designed to determine<br />

if serum HSP70 levels are elevated in patients with pancreatic cancer and can function as a biomarker<br />

for early detection <strong>of</strong> pancreatic cancer.<br />

Methods: Study subjects were divided into 3 groups – histologically proven pancreatic cancer (PC,<br />

n=23), chronic pancreatitis (CP, n=12) and matched normal control subjects (C, n=10). Serum HSP70<br />

levels were determined utilizing a novel immunoelectrophoresis method developed and validated by the<br />

authors. Significance <strong>of</strong> difference between the groups was analyzed with Analysis <strong>of</strong> Variance test<br />

(ANOVA). Receiver operating characteristic (ROC) curve analysis was performed to discriminate<br />

pancreatic cancer patients from normal controls.<br />

Results: The mean ± SE serum HSP70 levels in PC, CP and C groups were 1.68±0.083ng/ml,<br />

0.40±0.057ng/ml and 0.04ng/ml respectively. Serum HSP70 levels in PC group were significantly higher<br />

Methods: This prospective single-blinded randomized controlled trial enrolled newly diagnosed EoE<br />

patients in a treatment protocol. EoE was defined as patients with both clinical symptoms (dysphagia<br />

and food impaction) and meeting histologic criteria (>15 eosinophils/HPF). Patients underwent 24-hour<br />

pH/impedance monitoring to establish coexisting gastroesophageal reflux disease (GERD). Patients were<br />

then randomized to aerosolized swallowed fluticasone 440 mcg twice daily (FLU) or esomeprazole 40 mg<br />

Impact <strong>of</strong> Cyp2c19*2 Versus *3 Loss-<strong>of</strong>-function Allele on Response to High Maintenance-dose<br />

Clopidogrel in Patients Undergoing Percutaneous Coronary Intervention<br />

Katrina A. Abadilla, MD; Ily Kristine T. Yumul, MD<br />

Introduction: The U.S. FDA highlighted the role <strong>of</strong> genotyping in clopidogrel pharmacokinetics and<br />

clinical efficacy, and recommended the use <strong>of</strong> alternative treatment or treatment strategies in carriers<br />

with 2 loss-<strong>of</strong>-function (LoF) alleles <strong>of</strong> CYP2C19 gene (poor metabolizers). Whether doubling the<br />

maintenance dose <strong>of</strong> clopidogrel can provide adequate antiplatelet effect in the CYP2C19 poor<br />

metabolizers can be an important issue for personalized antiplatelet therapy.<br />

The prevalence <strong>of</strong> the CYP2C19 LoF variant is 55-70% among East Asians, which is much higher<br />

compared with Caucasians (25-35%). Also, 10-20% <strong>of</strong> Asians carry CYP2C19*3 allele, scarcely observed<br />

in Caucasians, and prevalence <strong>of</strong> poor metabolizers is 10-20% vs. ~5% in East Asians vs. Caucasians.<br />

We sought to assess the additive antiplatelet effect by doubling <strong>of</strong> clopidogrel dose depending on the<br />

CYP2C19 metabolic phenotype in PCI-treated East Asian patients. In addition, we compared the impact<br />

<strong>of</strong> the CYP2C19*2 and *3 LoF alleles on response to clopidogrel regimens.<br />

Methods: One hundred fifty five patients from a registry <strong>of</strong> the ACCEL (Adjunctive Cilostazol versus High<br />

Maintenance-dose ClopidogrEL) studies were collected. Elective percutaneous coronary intervention<br />

(PCI)-treated and acute myocardial infarction (AMI) post-emergent PCI patients were all on chronic<br />

clopidogrel therapy (75 mg > 5 days) prior to randomization. The current cohort then received<br />

clopidogrel 150 mg daily and aspirin 200 mg daily for 30 days. Adenosine diphosphate (ADP) (5 and 20<br />

µM)-induced platelet aggregations (PA) (maximal and 5-minute final) were evaluated using the AggRAM<br />

aggregometer. Genotyping for the CYP2C19*2/*3 variants was performed.<br />

Results: In this cohort, 63.9% <strong>of</strong> the total (n = 99) were carriers <strong>of</strong> the CYP2C19 LoF allele (*2 or *3):<br />

47.1% (n = 73) and 16.8% (n = 26) were intermediate and poor metabolizers, respectively. Platelet<br />

reactivity and the prevalence <strong>of</strong> high on-treatment platelet reactivity increased proportionally according<br />

to the number <strong>of</strong> the CYP2C19 LoF allele, irrespective <strong>of</strong> regimens <strong>of</strong> clopidogrel treatment. In contrast<br />

to extensive and intermediate metabolizers, the poor metabolizers showed significantly lower decreases<br />

Introduction: Pneumonia is a potentially devastating complication <strong>of</strong> stroke. A simple bedside dysphagia<br />

screen (DS) protocol can be used by healthcare providers to detect risk <strong>of</strong> aspiration in acute ischemic<br />

stroke (AIS) patients. We sought to identify those characteristics <strong>of</strong> acute ischemic stroke (AIS) patients<br />

associated with use <strong>of</strong> DS prior to any oral intake in the Get With The Guidelines-Stroke (GWTG-S)<br />

program.<br />

Methods: Data from 1256 GWTG-S hospitals from 04/01/2003 to 03/30/2009 were analyzed. DS was<br />

defined as the use <strong>of</strong> a bedside swallow screen prior to any oral intake. Patients who were kept strictly<br />

without oral intake (NPO) the entire hospital stay were excluded. Univariate analyses (chi-square for<br />

categorical variables or Wilcoxon for continuous variables) and multivariate logistic regression analyses<br />

were performed to identify independent factors associated with use <strong>of</strong> DS in AIS patients. In multivariate<br />

analyses, NIHSS was not included due to high rates <strong>of</strong> missing data (55%).<br />

Results: Among 446,056 ischemic stroke patients, 300,874 (67.4%) had DS performance documented.<br />

When compared with patients without DS, those with DS were slightly older, had higher NIHSS (when<br />

measured) and more frequently arrived by EMS and had a history <strong>of</strong> atrial fibrillation. They were less<br />

<strong>of</strong>ten diabetics, and had similar rates <strong>of</strong> prior stroke/TIA, dyslipidemia, PVD, and current<br />

Analysis <strong>of</strong> Chlamydia Infection Management -- a Quality Improvement Initiative<br />

Sandeep R. Somalaraju, M.D (Associate) Second Author: Maria Fahey, R.N Third Author: Alwyn Rapose,<br />

M.D<br />

Introduction: Sexually transmitted infections (STIs) are a major public health challenge, chlamydia being<br />

the most common, with 1.2 million cases reported to the CDC in 2009. Optimal management <strong>of</strong><br />

chlamydia by community practitioners is imperative in disease control, and the CDC has established<br />

guidelines for appropriate testing, therapy, as well as partner notification and testing. Management <strong>of</strong><br />

patients with chlamydia presenting to a multispecialty group practice was analyzed by the Infection<br />

Control Committee as one <strong>of</strong> its Quality Improvement measures.<br />

Methods: A retrospective chart review <strong>of</strong> patients with positive laboratory testing for chlamydia from<br />

October 2010 - March 2011 was performed. Data abstracted included demographics, medication<br />

prescribed, documentation <strong>of</strong> counseling recommending partner testing, and follow-up testing <strong>of</strong> index<br />

cases within a time frame <strong>of</strong> 3-12 months.<br />

Results: 74 patient charts were reviewed, <strong>of</strong> which 59 were from adult primary care clinics, 14 from<br />

pediatric clinics and 1 from OB/GYN clinic. Compliance was 100% with prescription <strong>of</strong> the<br />

recommended regimen for antibiotic treatment (81% patients received azithromycin; 19% received<br />

doxycycline), whereas test for cure was 92% having been booked for repeat testing within a 3-12 month<br />

follow-up. Counseling for partner testing was documented in 81% <strong>of</strong> patients.<br />

Conclusion: In this retrospective analysis we found that community practitioners in this multispecialty<br />

group were 100% compliant with the CDC recommended treatment regimen. In regards to follow up, a<br />

very high percentage <strong>of</strong> patients were scheduled for follow up testing to ensure cure, thus indicating<br />

that the majority <strong>of</strong> the physicians in this group practice were aware <strong>of</strong> this guideline. However,<br />

counseling for partner notification and testing was an area that needed improvement.<br />

While the appropriateness <strong>of</strong> chlamydia treatment in the form <strong>of</strong> antibiotic use was optimal, the<br />

Infection Control Committee recommended further education <strong>of</strong> the practitioners <strong>of</strong> the CDC guidelines<br />

regarding follow up testing <strong>of</strong> the index case and partner notification. This recommendation as a target<br />

for Quality Improvement in the clinic was forwarded to the Medical Director for Quality and Patient<br />

Safety.<br />

Fluid Balance as a Predictor <strong>of</strong> Readmission in Patients with Acute Decompensated Heart Failure<br />

Mostafa El-Refai, MD; Nikhil Ambulgekar, MD; Mario Njeim, MD; Waqas Qureshi , MD<br />

Introduction: Acute decompensated heart failure is one <strong>of</strong> the most common admitting diagnoses. It is<br />

unclear whether the documentation <strong>of</strong> fluid balance, which is sometimes incomplete, leads to any effect<br />

on readmission rates <strong>of</strong> these patients. The aim <strong>of</strong> this study is to assess the impact <strong>of</strong> fluid balance<br />

documentation as a predictor <strong>of</strong> 30 day readmission in heart failure patients.<br />

HYPOTHESIS: Complete documentation <strong>of</strong> daily fluid balance leads to a decrease in 30 day readmission<br />

rate and early discharge <strong>of</strong> the patients.<br />

Methods: We retrospectively reviewed data on 350 patients admitted to the hospital from January 2009<br />

till December 2009,that were discharged with a primary discharge diagnosis <strong>of</strong> heart failure. Out <strong>of</strong><br />

these, 38 patients were excluded since they were enrolled into hospice or required Milrinone therapy<br />

during the admission. We collected data on 312 patients regarding 70 clinical and echocardiographic<br />

variables that we thought might predict readmission. Complete documentation was defined as<br />

documentation <strong>of</strong> fluid balance in the first 24 hours <strong>of</strong> admission.<br />

Results: The mean age was 67.7 ± 16.8 years with 152 (48.7%) women. The patients were not different<br />

at baseline in regards to age, gender, race, prevalence <strong>of</strong> diastolic heart failure, and use <strong>of</strong> other forms<br />

<strong>of</strong> diuretics. On the other hand, they were found to be different in regards to ejection fraction, dose <strong>of</strong><br />

furosemide at discharge, daily dose <strong>of</strong> furosemide. A total <strong>of</strong> 173 (55.4%) were identified to have<br />

complete documentation. 92 (29%) <strong>of</strong> the patients were readmitted for heart failure. There was no<br />

difference in readmission rates <strong>of</strong> both groups but the length <strong>of</strong> stay was longer for patients with<br />

complete documentation. The mean doses <strong>of</strong> all forms <strong>of</strong> furosemide were higher in patients with<br />

complete documentation. Physician made more changes in the diuretic regimen, more x-rays were<br />

ordered, and more Foley's catheters were placed in the complete documentation group all with<br />

statistically significant P-values.<br />

Conclusion: The study highlights that accurate fluid balance documentation is not associated with a<br />

decrease in readmission rate but it may help us in many other decisions related to management <strong>of</strong> the<br />

hospitalized heart failure patient.<br />

Candida glabrata Fournier's Gangrene<br />

Shwan Mohamod Dhahir Jalal, MD, MBChB, Laurence Briski MD, Joel T. Fishbain MD<br />

Introduction: Fournier’s gangrene is an aggressive necrotizing skin and s<strong>of</strong>t tissue infection <strong>of</strong> the<br />

perineum. The disease is more prevalent in patients with diabetes mellitus and has been associated with<br />

urological or anorectal manipulation. Infections are most <strong>of</strong>ten polymicrobial and represent normal flora<br />

<strong>of</strong> the gastrointestinal tract as well as Staphylococcus aureus. Infections due primarily to Candida<br />

species are extremely rare and the finding non-albicans species even more so.<br />

Methods: Our patient was a 62 year old gentleman with past medical history significant for diabetes,<br />

hypertension, chronic kidney disease, cardiomyopathy and peripheral vascular disease. He was brought<br />

in to the Emergency Department because <strong>of</strong> altered mental status, scrotal pain, swelling and redness for<br />

the past 2-3 days. No fevers, chills or night sweats were reported. There was no recollection or report <strong>of</strong><br />

trauma and he did not have chronic Foley catheter. His physical examination was remarkable for lack <strong>of</strong><br />

fever and stable vital signs. His scrotum was markedly inflamed with induration, tenderness to minimal<br />

palpation but no obvious fluctuance, bullae, necrotic tissue or crepitus was appreciated. His blood sugar<br />

was 550, WBC count was 19,000 cells/mm3 and urinalysis showed 736 WBCs and large leukocyte<br />

esterase. CT scan revealed s<strong>of</strong>t tissue stranding in the perineum with air in the inguinal canal. The<br />

patient was taken to the operating room and underwent debridement. Intra-operative findings were<br />

notable for necrosis and some purulent fluid. Blood, urine and operative room cultures all yielded pure<br />

cultures <strong>of</strong> Candida glabrata.The patient was initially treated with broad spectrum antibiotics but<br />

therapy was changed to fluconazole (urinary tract penetration) and micafungin (s<strong>of</strong>t tissue penetration).<br />

The patient did well with additional wound care and debridement.<br />

Results: Fournier's gangrene is a necrotizing fasciitis <strong>of</strong> genitalia and perineum that mainly involves<br />

subcutaneous tissues. First described in 1883 by French dermatologist Jean Alfred Fournier. The disease<br />

can rapidly progress and It must be managed as a life-threatening emergency because <strong>of</strong> associated<br />

mortality. There are multiple risk factors that can predispose to Fournier's gangrene. The infection is<br />

typically polymicrobial in nature. Management includes aggressive medical treatment with broad<br />

spectrum antibiotics and immediate surgical debridement <strong>of</strong> all necrotic tissue. Follow-up debridment is<br />

recommended as a second look procedure. Our case represents the unusual occurrence <strong>of</strong> a single<br />

pathogen (previously only reported in 3 cases). Because C. glabrata may be resistant to fluconazole<br />

(testing was not readily available), this patient received an echinocandin for treatment. The presence <strong>of</strong><br />

the organism in the urinary tract, however, required the addition <strong>of</strong> fluconazole due to poor urine levels<br />

<strong>of</strong> echinocandins.<br />

Conclusion: Fournier’s gangrene is a life threatening condition which results in significant morbidity and<br />

mortality. Early recognition with aggressive surgical debridement and appropriate antimicrobial therapy<br />

is the mainstay <strong>of</strong> therapy. Our case represents a rare occurrence <strong>of</strong> a single pathogen whose presence<br />

is also rarely reported (C. glabrata).<br />

Department Of Internal Medicine, Henry Ford Hospital.<br />

Introduction: Despite advances in medical treatment for heart failure (HF), rates <strong>of</strong> death and<br />

readmission after hospitalization remain high and impact the entire health system resources. Recently,<br />

two large randomized controlled studies showed that telemonitoring does not intrinsically carry a<br />

significant benefit in terms <strong>of</strong> improving HF outcomes. This contradicts with the findings <strong>of</strong> previous<br />

systematic reviews and meta-analyses <strong>of</strong> small scale studies which showed benefits <strong>of</strong> such strategy.<br />

The aim <strong>of</strong> our study is to assess the benefits <strong>of</strong> adopting such strategy in a focused, patient centered<br />

team care clinic as opposed to the large multicenter studies.<br />

Methods: The study was a retrospective chart review and analysis <strong>of</strong> 212 patients who were enrolled in<br />

the "The Heart Failure Tele-Assurance Program" at tertiary medical center between the years 2007 and<br />

2011. Only patients with at least 6 months <strong>of</strong> adherence to the program after enrollment were included<br />

in the study. Analysis included data collected over a time period <strong>of</strong> 6 months prior to enrollment<br />

through 6 months after enrollment. The primary end-points were number <strong>of</strong> hospitalizations,<br />

emergency department (ED) visits and clinic visits, for any reason. Secondary end-points included<br />

hospitalization for HF, admission to the intensive care unit (ICU) and number <strong>of</strong> days in the hospital.<br />

Comparison <strong>of</strong> pre-enrollment data to post-enrollment data was done using Wilcoxon signed-rank tests.<br />

Results: Of the 212 patients that were included in the study, mean age was 71, 51% were female, and<br />

78% were African-<strong>American</strong>. Mean ejection fraction (EF) was 41%. There were significantly fewer overall<br />

Introduction: The technique <strong>of</strong> Sentinel Lymph Node Mapping (SLNM) varies between surgeons,<br />

centers/hospitals and countries in terms <strong>of</strong> type and amount <strong>of</strong> dye, pathologic examination <strong>of</strong> SLN,<br />

technical issues <strong>of</strong> dye injection. The purpose <strong>of</strong> this study is to evaluate the methods <strong>of</strong> lymphatic<br />

mapping in solid tumors around the world to create a form <strong>of</strong> international reference for all oncologists<br />

to use for patients with breast, melanoma and GI cancers.<br />

Methods: A web-based survey form was created with 12 questions in regards to various aspects <strong>of</strong><br />

SLNM for melanoma, breast, esophagus, stomach, colon and rectal cancers. This questionnaire was<br />

distributed to 425 centers in the U.S, 60 in Europe, and more than 60 in Japan. After the initial<br />

distribution in April 2010, the survey was re-submitted twice. By the end <strong>of</strong> June, 2011, the data was<br />

calculated for further analysis.<br />

Results: Out <strong>of</strong> the 545 centers that received the survey, 122 centers (22.3 %) responded. Of these 47<br />

are from U.S, 60 from Japan, and 15 from Europe. There are 13 centers that do not use lymphatic<br />

mapping. The order <strong>of</strong> frequency <strong>of</strong> the organ sites for lymphatic mapping was as follows: breast (80<br />

centers), melanoma (53 centers), stomach and esophagus (24 centers), and colorectal (19 centers).<br />

There were 56 centers that perform SLNM on one organ site, 39 perform on 2 organ sites, and 14<br />

centers perform on 3 organ sites. The most common mapping agents used for SLNM was Radiocolloid<br />

(breast 80%, melanoma 90%, upper GI 66% and colorectal 42%). For breast, the most common site <strong>of</strong><br />

injection was subareolar, while in upper GI submucosal, and in lower GI it was subserosal. Overall the<br />

average volume <strong>of</strong> injection for lymphatic mapping was 1-2 ml (range 0.4-5 ml). Pathological<br />

intraoperative interpretation varied from 74% in breast, 38% in melanoma, and 42% in upper GI and<br />

26% in lower GI.<br />

Conclusion: The technique <strong>of</strong> Sentinel Lymph Node Mapping (SLNM) varies between surgeons,<br />

centers/hospitals and countries in terms <strong>of</strong> type and amount <strong>of</strong> dye, pathologic examination <strong>of</strong> SLN,<br />

De Novo Dipstick Proteinuria (DP) as Predictor <strong>of</strong> Acute Kidney Injury (AKI) in Critically Ill Septic<br />

Patients<br />

Javier Neyra, MD George Maidaa, MD John Manllo, MD Gordon Jacobsen, MS Jerry Yee, MD, FACP, FASN<br />

Introduction: AKI occurs in nearly 30% <strong>of</strong> patients with severe sepsis and microalbuminuria has been<br />

described in up to 87% <strong>of</strong> septic patients.<br />

Methods: In order to determine the predictive value <strong>of</strong> de novo DP as an early biomarker <strong>of</strong> sepsisassociated<br />

AKI, we retrospectively analyzed data from patients with severe sepsis admitted to our<br />

institution’s intensive care units between 01/2004 and 07/2011 for DP. Exclusion criteria included a<br />

baseline serum creatinine (SCr) level > 1.5 mg/dL, presence <strong>of</strong> DP within 3 months <strong>of</strong> the index<br />

admission date and common causes <strong>of</strong> false-positive DP, e.g., urinary tract infection or gross hematuria.<br />

Results: A total <strong>of</strong> 2,252 patients were screened and 470 were included in the study. Of these, 328<br />

patients underwent DP-testing at admission. The SCr increased > 0.3 mg/dL in 210 (64%) subjects within<br />

the first 72 hours <strong>of</strong> admission. In this group, new onset DP was found in 114 (54%) subjects (p < 0.001;<br />

PPV, 75%) and in 91 <strong>of</strong> 166 (55%) subjects with AKI by AKIN criteria (p = 0.002; PPV, 60%). By<br />

multivariable logistic regression (age, gender, race, comorbidities, hemodynamic status, etc.), de novo<br />

DP at time <strong>of</strong> admission independently predicted AKI (odds ratio [OR] 2.3, 95% confidence interval [CI]<br />

1.4 -3.8, p = 0.001).<br />

Conclusion: De novo DP represents a simple, inexpensive biomarker in sepsis with predictive power for<br />

AKI. Further studies are required to fully elucidate the significance <strong>of</strong> new onset DP in AKI.<br />

Introduction: Introduction: A transesophageal echocardiography (TEE) is recommended in the<br />

diagnostic evaluation <strong>of</strong> patients with proven or suspected (cardiovascular implantable<br />

CIED infections is unclear.<br />

Methods: We performed a retrospective study <strong>of</strong> hospitalized patients with CIED infections at our<br />

institution between 2000 and 2009. Data collected included: demographics, device specific information<br />

(pocket versus lead-associated endocarditis (LAE), microbiology, TEE results (abnormal defined as lead<br />

or valve vegetation) and outcomes (device removal, discharge or death due to CIED infection). Patients<br />

with LAE were identified by positive lead cultures and/or blood cultures in the absence <strong>of</strong> pocket<br />

infection. Patients with pocket infections were identified by documentation <strong>of</strong> local evidence <strong>of</strong><br />

infection. Outcomes (lead extraction rates, mortality, and duration <strong>of</strong> antibiotics) were compared in<br />

patients who had a TEE performed or not using x2 and ANOVA. A p < or = 0.05 was considered<br />

Results: 91 patients were included in the study (39 LAE and 52 pocket infections). The two study groups<br />

were comparable in terms <strong>of</strong> mean age and gender distribution. Patients with LAE were more likely than<br />

Combination <strong>of</strong> 5FU and Difluorinated Curcumin is a Promising Therapeutic Strategy to Target Gastric<br />

Cancer Stem Cells<br />

Anuradha Poolla, MD., MPH., Shailendar S. Kanwar, Ph.D., Adhip P.N. Majumdar Ph.D., DSc.<br />

Introduction: Despite advances in medicine, mortality from gastric cancer, the second leading cause <strong>of</strong><br />

cancer deaths world wide, remains unacceptably high. Current therapeutic regimen consisting <strong>of</strong> 5<br />

Fluorouracil (5FU) or 5FU + Oxaliplatin (Folfox), the mainstay <strong>of</strong> gastrointestinal cancer therapeutics,<br />

shows only a limited success that results in 40-60% recurrence. Although the reasons for this high<br />

recurrence are not fully understood, one possible reason could be the presence <strong>of</strong> cancer stem cells<br />

(CSCs) which are highly chemo-resistant and possess the limitless capacity to regenerate/proliferate. We<br />

have recently demonstrated that the combination <strong>of</strong> Curcumin or its novel analog Diflurinated Curcumin<br />

(CDF) with Folfox is highly effective in eliminating/ reducing colon CSCs. To determine whether a similar<br />

therapeutic regimen would also be effective in eliminating gastric CSCs, the present investigation was<br />

undertaken.<br />

Methods: We examined the effects <strong>of</strong> 5FU and CDF, each alone, and the combination <strong>of</strong> both on the<br />

growth <strong>of</strong> gastric cancer cells and expression <strong>of</strong> gastric CSC markers (CD-44, CD-166, ABCG-2, ALDH-<br />

1). AGS, a gastric cancer cell line, originally derived from gastric adenocarcinoma was used.<br />

Results: We observed that, although 5FU (6µM) caused about 40% reduction in cellular growth, it<br />

produced a staggering 100-200% induction in CD-166 and ALDH-1 expression. However, when we<br />

combined 5FU with CDF, we observed a marked 70% reduction in cellular growth, accompanied by a<br />

significant 20-40% inhibition <strong>of</strong> CD-166 and ALDH-1 expression, indicating reduction in CSC population.<br />

No apparent change in the expression <strong>of</strong> either CD-44 or ABCG-2 was observed with either <strong>of</strong> the<br />

treatment.<br />

Conclusion: In conclusion, our data suggests that the combination <strong>of</strong> 5FU and CDF could be a promising<br />

therapeutic strategy to target the gastric CSCs which might lead to improved survival/delayed<br />

recurrence.<br />

Introduction: Infection control and hospital epidemiology are analagous to public health practices<br />

directed at health care settings. Prophylactic measures in health care delivery settings have become<br />

essential to precluding nosocomial infections; the spread <strong>of</strong> multi-drug resistant pseudomonas<br />

in Intensive Care Unit (ICU) setting can be contained with consistent use <strong>of</strong> preventative methods.<br />

Methods: This is a clinical quality assurance project to reduce clustering <strong>of</strong> multi-drug resistant<br />

pseudomonas in neuro ICU. There was serial case reporting <strong>of</strong> MDR pseudomonas in about 10 patients<br />

during the same time period. A committee was established to find out the possible environmental<br />

factors contributing the spread <strong>of</strong> MDR pseudomonas. It was found that the shallow sinks(culture<br />

Introduction: There were approximately 58,000 new cases <strong>of</strong> renal cell carcinoma in the U.S. last year,<br />

85% <strong>of</strong> which were clear cell renal cell carcinoma (ccRCC). Cardiac metastasis from renal cell carcinoma<br />

in the absence <strong>of</strong> vena cava extension is an exceedingly rare entity. It has been postulated that RCCs<br />

have two distinct routes <strong>of</strong> spread leading to different presentations and outcomes.<br />

Methods: We present two cases <strong>of</strong> ventricular metastases from renal cell carcinoma without vena cava<br />

or right atrial involvement. We treated these two patients with sunitinib, a tyrosine kinase inhibitor,<br />

and followed their subsequent clinical courses with routine <strong>of</strong>fice visits as well as serial echocardiograms<br />

and cardiac MRIs.<br />

Results: The first case involves an initially isolated inoperable metastasis to the left ventricle, which was<br />

treated with systemic targeted therapy with favorable local response shown by serial MRIs. Our second<br />

case illustrates a patient with an isolated metastasis in the interventricular septum with extension into<br />

the right ventricle, which has also remained stable in size on sunitinib. No significant drug toxicity has<br />

been demonstrated in either case.<br />

Conclusion: We describe our management <strong>of</strong> these two cases and discuss the current medical and<br />

surgical approaches to the treatment <strong>of</strong> cardiac metastases from renal cell carcinoma. Currently,<br />

combination therapy that includes surgical debulking and systemic treatment affords the best chance <strong>of</strong><br />

palliation. For patients whose tumors prove to be inoperable, based on the findings in our two cases,<br />

we propose that targeted therapy with tyrosine kinase inhitors is a viable and safe therapeutic<br />

alternative to metastasectomy.<br />

Introduction: Chronic obstructive pulmonary disease (COPD) is a leading cause <strong>of</strong> hospitalizations and<br />

mortality in the United States. Exacerbations <strong>of</strong> COPD are best treated with corticosteroids and by<br />

addressing the underlying cause <strong>of</strong> decompensation. In practice, the dose and route <strong>of</strong> steroid<br />

administration in COPD exacerbations varies widely.<br />

Methods: We performed a literature review to identify the effectiveness <strong>of</strong> various steroid doses and<br />

administration routes used in the treatment <strong>of</strong> COPD exacerbations. We then examined the current<br />

steroid administration practices used for all patients admitted to Regions Hospital in St. Paul, Minnesota,<br />

with a primary diagnosis <strong>of</strong> COPD exacerbation between January 2010 and December 2010.<br />

Results: A review <strong>of</strong> the literature identified five key studies <strong>of</strong> steroid use in COPD exacerbations. The<br />

earliest <strong>of</strong> these studies demonstrated the benefits <strong>of</strong> using methylprednisolone 125 mg IV vs. placebo.<br />

Side effects related to this dose included hyperglycemia and upper GI bleeding. Subsequent studies have<br />

compared lower oral doses (20 to 80mg prednisone equivalent) to high IV doses and found low-dose<br />

oral steroids to be equally effective with fewer side effects. Among patients admitted for COPD<br />

exacerbation at Regions Hospital in Saint Paul, Minnesota (n=225), 39% received low-dose (20 to 80 mg<br />

prednisone equivalent) oral prednisone in the emergency department. Twenty-two percent received<br />

higher doses or IV doses in the emergency department. The initial inpatient steroid dose <strong>of</strong> these same<br />

patients revealed that 66% versus 33% received low-dose compared to high-dose or IV steroids,<br />

Introduction: Pulmonary arterial hypertension (PAH) is a devastating condition characterized by<br />

pulmonary vascular remodeling and right heart failure. Outcome is determined by right heart<br />

adaptation, but conventional echocardiographic measures are limited due to complex right ventricular<br />

geometry and translational motion. Speckle-tracking echocardiography is a novel angle-independent<br />

technology used to assess myocardial strain (a sensitive measure <strong>of</strong> ventricular function). Furthermore,<br />

the right (RV) and left ventricles (LV) share a common pericardial sac and septum. Hence it is plausible<br />

that in PAH, where the RV but not LV faces a marked increase in afterload, a dysfunctional RV may<br />

impart abnormalities on LV function through ventricular interdependence. We sought to correlate RV<br />

and LV strain patterns with clinical outcomes in PAH.<br />

Methods: Hemodynamic catheterization and 2D, Doppler and speckle tracking strain transthoracic<br />

echocardiography were performed in 82 consecutive adults with PAH. Cox proportional hazards<br />

regression models were used to identify correlates <strong>of</strong> mortality. Survival was assessed over two years.<br />

Results: Patients had catheter-confirmed PAH (mean PA pressure 49 ± 10 mm Hg; normal -25%). LV<br />

free wall longitudinal systolic strain was concomitantly reduced at -15±3% (normal > -18%) despite<br />

apparently normal LV systolic function (LVEF 65 ± 8%). A delayed relaxation mitral inflow pattern<br />

predicted worse outcome (2-year survival 45% [95% CI 26-66] versus 83% [71-91], p

Introduction: Microalbuminura independently predicts cardiovascular disease risk; endothelial function<br />

may provide a potential biological mechanism to explain this association. There is evidence in<br />

associated with microalbuminuria in men and F-RHI was weakly significantly (P=0.08) associated with<br />

microalbuminuria in women.<br />

Conclusion: We found using digital arterial tonometry a significant relation between endothelial tone<br />

and microalbuminuria in men and between endothelial dysfunction and microalbuminuria in<br />

women. These findings support the theory that microalbuminuria is an early marker <strong>of</strong> vascular disease<br />

and may help to explain the link between the presence <strong>of</strong> microalbuminuria and the development <strong>of</strong><br />

cardiovascular atherosclerotic disease in diabetics.<br />

Angiotensin 1-7 Protects against Renal Ischemia Reperfusion Induced Acute Kidney Injury and its<br />

Associated Cardiac Dysfunction<br />

Arnaldo Lopez-Ruiz Andrea Soljancic Kiran Chandrashekar Ruisheng Liu Luis A. Juncos<br />

Introduction: Acute kidney injury induces inflammatory changes which can lead to acute cardiac<br />

dysfunction (type 3 cardiorenal syndrome). Angiotensin-(1-7) (Ang 1-7) is a clinically relevant Ang<br />

subtype that exerts cytoprotection through its cardiovascular and baroreflex actions which counteract<br />

those <strong>of</strong> Ang II on the renin-angiotensin system.. We hypothesized that exogenous infusion <strong>of</strong> Ang1-7<br />

protects against Ischemia/reperfusion (I/R) induced AKI and its subsequent cardiac sequelae.<br />

Methods: Male SD rats (n=6/group) were randomized into 4 groups, 1) Sham, 2) AKI, 3) AKI+Ang1-7, 4)<br />

AKI+ Ang1-7+ A779 (Ang 1-7 antagonist). AKI was induced by I/R, through bilateral renal pedicle<br />

clamping for 40mins. Ang1-7 and its antagonist were given daily at 574 µg/kg or 1148 µg/kg i.p<br />

respectively, starting 1 hr before I/R and continuing for 3 days after the renal insult. During follow up,<br />

plasma creatinine and urinary NGAL (renal injury marker) were measured. The rats were sacrificed and<br />

the kidneys and hearts collected to estimate inflammation (TNFa), cardiac stress (BNP) and VEGF (which<br />

may have cytoprotective effects).<br />

Results: We noted that AKI is associated with reduced levels <strong>of</strong> Ang 1-7 in the kidneys (1.3±0.2 vs.<br />

3.9±0.3 ng/ml) and the heart (1.7±0.1 vs. 2.9±0.2 ng/ml) compared to shams. AKI also increased cardiac<br />

tissue levels <strong>of</strong> BNP (4.8±0.4 vs. 0.3 ± 0.05ng/ml) and renal and cardiac TNFa expression (86±5 vs.<br />

4.8±0.7 and 54±6 vs. 4.1 ±0.7pg/ml respectively) compared to sham. However, rats with AKI that were<br />

given an exogenous infusion <strong>of</strong> Ang1-7 had lower renal dysfunction (plasma creatinine decreased from<br />

2.5±0.2 to 1.6±0.15 mg/dl) and injury (NGAL decreased from1340±132 to 615±84UI/ml) compared to<br />

shams. Additionally exogenous Ang1-7 infusion also attenuated renal and cardiac TNFa expression (86±5<br />

vs. 36.2±4.2 and 54±6 vs. 28.7±7.5 pg/ml respectively), and blunted cardiac BNP (4.8±0.4 to 2.8±0.3<br />

ng/ml). Moreover, exogenous Ang1-7 ameliorated AKI-induced decrease in renal and cardiac VEGF<br />

expression (from 97.4±10 to 198± 21 and 174±23 to 276±21 pg/ml respectively). These beneficial effects<br />

<strong>of</strong> Ang 1-7 were abolished by administration <strong>of</strong> its antagonist.<br />

Conclusion: Hence renal I/R-AKI contributes to cardiac dysfunction and is associated with inflammation<br />

and injury and exogenous Ang 1-7 confers protection against I/R- AKI, perhaps by enhancing levels <strong>of</strong><br />

potential cytoprotectants, including VEGF.<br />

Tuberculosis Mortality in a High HIV Prevalent Setting<br />

Dominique J Pepper, MD Co-authors: Feriyl Bhaijee, MD, Wanmei Wang, Imran Sunesara, Suzaan<br />

Marais, MD, Robert J. Wilkinson, MD, Virginia de Azevedo, MD, Gary Maartens, MD.<br />

Introduction: Tuberculosis (TB) is the leading infectious cause <strong>of</strong> death worldwide, especially among<br />

those infected with HIV. One strategy to reduce TB-related mortality is to identify and target groups <strong>of</strong><br />

TB patients that are at increased risk <strong>of</strong> death. We undertook to determine relationships between TBrelated<br />

mortality and age, gender, and HIV status.<br />

Methods: We analyzed a surveillance population <strong>of</strong> 12,045 TB patients who were organized by gender,<br />

HIV status, and degree <strong>of</strong> immune suppression into the following groups: HIV uninfected (Male/Female:<br />

2,409/1,525), HIV-infected with a CD4 count > 350 cells/microL (M/F: 1,665/2,253), and HIV-infected<br />

with a CD4 count < 350 cells/microL (M/F: 1,901/2,292). For each group, we calculated age-specific TB<br />

mortality proportions, determined adjusted odds ratios (aOR) for death, and performed logistic<br />

regression analysis. We also created Cox-Proportional hazard models to determine hazard ratios (HR) for<br />

death.<br />

Results: We found a previously unexplored curvilinear relationship between TB-related mortality and<br />

age, gender, and HIV status: increasing age (HR=1.6, 95%CI: 1.51-1.76) and advancing degree <strong>of</strong><br />

immune-suppression (HR=1.5, 95%CI: 1.33-1.64) were significantly associated with an increasing hazard<br />

<strong>of</strong> death, while gender was not (HR=1.0, 95%CI: 0.84-1.22). All HIV-infected patients <strong>of</strong> 15 years age or<br />

older were at increased risk <strong>of</strong> death (aOR=2.3, 95%CI: 1.95 – 2.79). Among TB patients <strong>of</strong> 55 years age<br />

or older, HIV-infected women were more likely to die than HIV-infected men (aOR=3.7, 95%CI: 1.83 –<br />

7.34), while HIV uninfected men were more likely to die than HIV uninfected women (OR=1.9, 95%CI:<br />

1.01 – 3.43).<br />

Conclusion: Novel features <strong>of</strong> this work are the curvilinear relationships between TB-related mortality<br />

and age, gender, and HIV status. Furthermore, these data add impetus to current WHO and CDC<br />

guidelines that antiretroviral treatment be initiated among all HIV-infected adults with active TB disease,<br />

irrespective <strong>of</strong> CD4 cell count. Among TB patients <strong>of</strong> 55 years age or older, interventions should be<br />

prioritized in HIV-infected women and HIV uninfected men.<br />

Angiotensin II Stimulate TNF-Alpha in a Hyperandrogenic Female Rat<br />

Licy L. Yanes Cardozo, MD, Damian G. Romero, PhD and Jane F. Reckelh<strong>of</strong>f, PhD<br />

Introduction: Hyperandrogenic conditions in women such as polycystic ovary syndrome (PCOS) and<br />

postmenopause are associated with high risk <strong>of</strong> cardiovascular diseases. However the precise<br />

mechanisms by which increases in androgens promote cardiovascular disease in women are unknown.<br />

We have recently reported that androgen administration to female Sprague Dawley rats, beginning at 4<br />

wks <strong>of</strong> age (prepubertal), increases blood pressure (BP), inflammatory cytokines levels such as Tumor<br />

Necrosis Factor-alpha (TNF-a), food intake, fat deposits, and plasma leptin and insulin. Androgens<br />

increase Ang II levels in several hypertensive animal models. In the present study, we tested the<br />

hypothesis that activation <strong>of</strong> intrarenal renin-angiotensin system (RAS) increases blood pressure and<br />

inflammatory cytokines in the hyperandrogenic female (HAF) rats.<br />

Methods: Dihydrotestosterone (DHT) pellets (7.5 mg/90 days, sc, HAF rats) or placebo pellets, were<br />

implanted in female Sprague Dawley rats (n=10) at 4 weeks <strong>of</strong> age. After 1 mos <strong>of</strong> DHT treatment,<br />

enalapril (250 mg/l, drinking water) was administered for 2 mos. Mean arterial pressure (MAP) was<br />

measured by radiotelemetry for the last 2 weeks <strong>of</strong> treatment and kidneys were harvested for<br />

determination <strong>of</strong> TNF-a levels by ELISA.<br />

Results: HAF had higher MAP compared to placebo animals (108±2 vs. 96±1 mm Hg, p

Quality Improvement <strong>of</strong> ANCA Testing Process at MU - A 12 Month Data Review<br />

Delene Musielak, MD; Emily Larson, DO; Chokkalingam Siva, MD, MS; Menka Desai, MD; Darcy<br />

Folzenlogen, MD Division <strong>of</strong> Rheumatology, Department <strong>of</strong> Internal Medicine<br />

Introduction: Anti Neutrophil Cytoplasmic Antibodies (ANCA) are useful to diagnose certain vasculitides,<br />

but are <strong>of</strong>ten nonspecific. Guidelines and gating policies have been proposed to discourage<br />

inappropriate use which can lead to erroneous diagnoses and improper treatments.<br />

Case example: A 61-year-old female was transferred to the University Hospital after prolonged<br />

hospitalization elsewhere. She had been admitted earlier for septic arthritis in the wrist and developed<br />

deep venous thrombosis and pulmonary embolism in the hospital. Random serological testing lead to a<br />

positive P-ANCA result and a diagnosis <strong>of</strong> “P-ANCA vasculitis” without further evidence. High dose<br />

steroids for several weeks lead to multiple intra-peritoneal and s<strong>of</strong>t tissue abscesses and osteomyelitis.<br />

The patient became disabled from the iatrogenic complications <strong>of</strong> prolonged steroid use. She does not<br />

have evidence <strong>of</strong> vasculitis three years post discharge.<br />

Methods: A database with all consecutive ANCA requests at MU has been established beginning June 1 st<br />

2009. Medical records on requests for the first 12 months were reviewed for testing indications (table1).<br />

The data was analyzed to review whether the requests met the 1999 ANCA testing guidelines.<br />

Results: Only 27% <strong>of</strong> ANCA tests were ordered according to the guidelines since 417/570 (73%) <strong>of</strong><br />

requests did not meet the 12 testing criteria. The top most common reasons tests were ordered outside<br />

<strong>of</strong> criteria were hepatitis/cirrhosis (36%), other non-specific symptoms (18%) and hemochromatosis<br />

(0.6%).<br />

Conclusion: 73% <strong>of</strong> requests did not meet testing criteria, and per guidelines are deemed inappropriate.<br />

For quality improvement, data will be monitored and the information will be shared with the requesting<br />

physicians. Additional research regarding education <strong>of</strong> providers requesting tests and diagnosis<br />

outcomes <strong>of</strong> those in whom the test was ordered is underway.<br />

Inhibition <strong>of</strong> Vascular Smooth Muscle Cell Migration by a Novel Tiplaxtinin Eluting Stent<br />

Mayank K Mittal,Tammy Strawn, William P Fay<br />

Introduction: Plasminogen activator inhibitor-1 (PAI-1), a key regulator <strong>of</strong> the plasminogen activator<br />

(PA) system and fibrinolysis, also regulates vascular remodeling. Elevated levels <strong>of</strong> PAI-1 are associated<br />

with the development <strong>of</strong> intimal hyperplasia. The purpose <strong>of</strong> this study was to develop and characterize<br />

intravascular stents capable <strong>of</strong> eluting a pharmacological inhibitor <strong>of</strong> PAI-1, tiplaxtinin.<br />

Methods: Tiplaxtinin was coated on bare metal stents with a spray apparatus using polylactic-co-glycolic<br />

acid as the binding polymer. Scanning electron microscopy revealed uniform stent coating. HPLC<br />

analysis <strong>of</strong> aqueous eluates <strong>of</strong> tiplaxtinin-coated stents revealed sustained elution <strong>of</strong> tiplaxtinin from<br />

stents for up to 21 days. To determine if tiplaxtinin eluting from stents retained activity and inhibited<br />

smooth muscle cell migration, tiplaxtinin- and vehicle-control-coated stents were placed in transwell cell<br />

migration apparati along with human coronary artery SMC. PDGF-BB-induced cell migration was<br />

measured.<br />

Results: Tiplaxtinin-coated stents inhibited SMC migration by 89.1 ± 10.2 % compared to control (p<br />

Vitamin D Deficiency and Statin Associated Myopathy: A Systematic Review<br />

Prasad, Swati Kominneni, Vijaya Sontineni, Siva Hurley, John<br />

Introduction: Statin therapy is frequently used for atherosclerotic disease prevention and myopathy<br />

associated with it prevents the optimal use <strong>of</strong> these agents. Vitamin D deficiency has emerged as a<br />

factor in statin associated myopathy and the therapeutic role <strong>of</strong> vitamin D supplementation to improve<br />

statin tolerance is unclear. Our objective is to study the impact <strong>of</strong> vitamin D deficiency and<br />

supplementation on statin induced myalgia.<br />

Methods:A retrospective analysis <strong>of</strong> all published studies in the English language literature that have<br />

reported on vitamin D deficiency and myalgias associated with statin therapy was conducted. An Online<br />

search <strong>of</strong> Pub Med database and Google Scholar results using the following search terms - “statins,<br />

vitamin D deficiency, 25 (OH) vitamin D, vitamin D supplementation, myalgias, statin induced myopathy,<br />

statin associated myopathy”. Studies with subjects on statin therapy, a measured vitamin D level and<br />

reported frequency <strong>of</strong> symptomatic myalgia or myopathy were included for the analysis. Studies with<br />

subjects having myalgia due to identifiable causes including steroid therapy, hypo/hyperthyroidism,<br />

fibromyalgia, electrolyte abnormalities, and/or prior vitamin D supplementation were excluded from<br />

analysis.<br />

Results: A total <strong>of</strong> 2177 articles were retrieved, after initial review six studies were considered relevant<br />

and addressed Vitamin D deficiency among patients on statin therapy. Of the six relevant studies, a total<br />

<strong>of</strong> 10801 subjects were on statin therapy for treatment <strong>of</strong> hyperlipidemia. Mean age <strong>of</strong> total study<br />

patients were 59.6+5.1 years and male to female ratio was 2.5. Among the total subjects, 2309 patients<br />

had a measured serum Vitamin D level and were included for pooled analysis. Vitamin D deficiency<br />

(defined as < 32ng/ml for this study) was present in 52% (n=1202) <strong>of</strong> patients. Myalgia was present in<br />

16% (n=371) <strong>of</strong> the included subjects and 25% (n= 301) <strong>of</strong> the Vitamin D deficient subjects who were on<br />

statin therapy. Vitamin D replacement therapy in average conventional doses <strong>of</strong> 50,000 units/week for<br />

12 weeks was reported in 50% (n=153) <strong>of</strong> the Vitamin D deficient patients with myalgia resulting in<br />

normalized levels. We found 81.5% (n=125) <strong>of</strong> the Vitamin D replaced subjects became statin tolerant<br />

upon re-institution <strong>of</strong> same or different statin.<br />

Conclusion: We conclude that Vitamin D deficiency is a significant factor underlying myalgia among<br />

statin intolerant patients. Vitamin D replacement improves myalgia in such patients along with<br />

improving tolerance to statins for the treatment <strong>of</strong> hyperlipidemia and subsequent prevention <strong>of</strong><br />

atherosclerotic disease.<br />

Antiproliferative, Antiinvasive and Chemosensitizing Effects <strong>of</strong> Holy Basil leaf extracts in Human<br />

Pancreatic Cancer Cells Suggests its Potential Utility as a Source for Novel Anticancer Compounds<br />

M.S.,Surinder K Batra Ph.D.<br />

Introduction: Pancreatic cancer (PC) therapy is currently limited by intrinsic resistance <strong>of</strong> cancer cells to<br />

available chemotherapeutics. This has fuelled research into alternative therapies, particularly<br />

phytochemicals. Ocimum sanctum (or “Holy basil”), a medicinal herb found in semitropical and tropical<br />

parts <strong>of</strong> India, has been used for thousands <strong>of</strong> years in traditional medicine to treat diverse ailments.<br />

However, its effect on cancer cells remains largely unknown. The objective <strong>of</strong> our study was to<br />

investigate whether ethanolic extracts <strong>of</strong> O.sanctum leaves (EEOL) or the essential oil <strong>of</strong> O.sanctum<br />

leaves (EOOS) could inhibit aggressiveness <strong>of</strong> PC cells in vitro and alter their sensitivity to existing<br />

chemotherapeutics.<br />

Methods: Dried basil leaves were purchased from four different vendors (New Chapter Inc (NC),<br />

Superior Herbs (SH), ClubNatural (CN) and Morpheme (Morph)) and EOOS from Now Foods<br />

(Bloomingdale, IL). PC cells (ASPC-1, MiaPaca, Capan-1 and HPAF/CD18) grown under standard culture<br />

conditions were treated with either EEOL or EOOS diluted in culture medium. The optimum dose for in<br />

vitro studies was determined from a combination <strong>of</strong> the IC-50 values, in vitro effects on clonogenecity<br />

and growth kinetics and ability to downregulate MUC4 expression in vitro (in Capan-1 and HPAF/CD18<br />

PC cells). MUC4, a membrane bound glycoprotein has been demonstrated to promote survival,<br />

metastasis and chemoresistance in PC cells and hence was used as a surrogate marker <strong>of</strong> O.sanctum’s<br />

anti-PC effect. In vitro assays for migration, invasion, cell cycle, apoptosis and chemosensitivity were<br />

carried out.<br />

Results: EEOL <strong>of</strong> NC was the most effective (IC50 range- 0.7-127 µg/ml) and that <strong>of</strong> CN the least effective<br />

(IC50 range- 74-2,086 µg/ml) in inhibiting proliferation <strong>of</strong> PC cells in vitro. IC-50 for EOOS ranged from<br />

5X10 -4 to 0.17 %v/v. The optimum concentration <strong>of</strong> EEOL and EOOS that inhibited PC cell growth were<br />

determined to be 80µg/ml and 0.1% v/v respectively. EOOS/EEOL significantly inhibited cell cycle<br />

progression, induced apoptosis (EEOL>EOOS) and inhibited migration and invasion in PC cells. Pretreatment<br />

with EEOL/EOOS significantly increased the sensitivity <strong>of</strong> PC cells to Cisplatin, Docetaxel and<br />

Herceptin while a combination <strong>of</strong> EEOL/EOOS and chemotherapeutics was more effective than the<br />

individual drugs alone. EEOL/EOOS also significantly downregulated the expression <strong>of</strong> genes that<br />

regulate proliferation, migration and invasion including MUC4, activated ERK-1/2, FAK, p65 (subunit <strong>of</strong><br />

NF-kB) and N-cadherin.<br />

Conclusion: EEOL/EOOS have potent anti-proliferative, anti-motility, anti-invasive and chemosensitizing<br />

effects on PC cells. Our results suggest that O.sanctum leaves could be a novel source <strong>of</strong> antineoplastic<br />

compounds for therapy <strong>of</strong> PC.<br />

The Study <strong>of</strong> Bone Remodeling Activity in a Mouse Model <strong>of</strong> Osteogenesis Imperfecta<br />

Zhang, Hao, MD, PhD Pleshko, Nancy, PhD Jaffe, Eric, MD.<br />

Introduction: The goal <strong>of</strong> the current study is to investigate bone remodeling <strong>of</strong> Osteogenesis<br />

Imperfecta (OI) in an in vitro calvaria-Osteoclast (OC) co-culture system from wild type and OI (oim/oim)<br />

mice, a model <strong>of</strong> moderate-to-severe OI.<br />

Methods: Calvarias and bone marrow cells were harvested from 4-8 week old wild type and oim/oim<br />

mice. Calvarias and bone marrow cells were cultured in a-MEM containing 10% FBS in the presence <strong>of</strong><br />

10 -8 M 1, 25-(OH)2D3 and 10 -6 M prostaglandine E2 at 37 0 C for 14 days. The OBs from the calvaria<br />

migrated and spread into the culture plate, supporting the differentiation <strong>of</strong> OCs on the surface <strong>of</strong> both<br />

culture plate and calvaria. Two groups were examined: 1) wild type calvaria cultured with wild type OCs;<br />

2) oim/oim calvaria cultured with oim/oim OCs. After 14 days, calvarias were scanned by SEM to assess<br />

resorption pits. Culture plates with OCs and OBs attached were TRAP-stained to identify OCs and ALPstained<br />

to identify OBs. Ratio <strong>of</strong> OC/OB was calculated. RNA from each sample was reverse transcribed,<br />

and levels <strong>of</strong> RANKL and OPG gene expression were quantified by real time PCR and were detected on a<br />

MyiQ Single Color Real Time PCR detection system.<br />

Results: At day 14, there were significantly fewer number <strong>of</strong> OCs from the oim/oim group compared to<br />

Promoting Empathy and Understanding <strong>of</strong> Poverty Among Medical Students and Residents Through<br />

the Use <strong>of</strong> a ‘Poverty Simulation’<br />

Sreelatha Naik, MD Neil Kothari MD, Sophia Chen DO<br />

Introduction: Most future physicians enter medicine pr<strong>of</strong>essing a desire to help those in need. During<br />

the course <strong>of</strong> medical training, however, physicians-in-training can become detached from their initial<br />

idealism. This decrease in empathy has been attributed to an emphasis on objectivity and potential<br />

development <strong>of</strong> ‘elitism.’ In addition, students from affluent backgrounds may find it difficult to<br />

understand the hardships faced by patients living in poverty. Although 14.3% <strong>of</strong> <strong>American</strong>s live in<br />

poverty, approximately 60% <strong>of</strong> medical students are from the upper quintile <strong>of</strong> income. Positive patient<br />

perceptions <strong>of</strong> physician empathy improve information exchange and trust, which improve patient<br />

satisfaction and compliance. Therefore, enhancing trainees’ ability to empathize with patients may<br />

improve clinical outcomes.<br />

Methods: An interactive Poverty Simulation (developed by the Missouri Association for Community<br />

Action) was implemented for Internal Medicine residents and second-year students at UMDNJ – New<br />

Jersey Medical School, in which participants experience some <strong>of</strong> the stressors faced by those living in<br />

poverty. The objectives were to describe the influence <strong>of</strong> societal factors on poverty, to become aware<br />

<strong>of</strong> the barriers faced, and to exhibit greater sensitivity to the realities <strong>of</strong> living in poverty.<br />

72 residents and students were randomized into families <strong>of</strong> four members each. They received packets<br />

including family pr<strong>of</strong>ile and resources. Trainees assumed the identity <strong>of</strong> family members and roleplayed<br />

over several hours. Participants also completed optional pre- and post-surveys, which contained<br />

16 items that addressed participants’ perceptions about poverty. 62 (86%) completed at least one <strong>of</strong><br />

the surveys. Faculty then led discussions with participants about how their attitudes changed due to the<br />

simulation.<br />

Results: Three items demonstrated statistically significant differences, while two others trended<br />

toward significance.<br />

25.8% <strong>of</strong> participants believed that the poor get “a lot <strong>of</strong> breaks” with respect to expenses such<br />

98<br />

as rent and utilities vs. only 10.2% post-simulation (p=0.026).<br />

66.1% felt that poor people could improve their situation if they applied themselves vs. 41.7%<br />

post (p=0.007).<br />

41.9% felt that the poor “spend too much money on fast food” vs. 23.3% post-simulation<br />

(p=0.029).<br />

52.5% felt that poor people in this country “have it great compared to poor people in other<br />

countries” vs. 38.3% post (p=0.119). 62.3% felt that the community provided effective services<br />

to families vs. 48.3% post-simulation (p=0.122).


Conclusion: The data suggests that this half-day simulation significantly increased the understanding <strong>of</strong><br />

poverty in our medical students and residents. However, the data is limited due to the small size <strong>of</strong> this<br />

pilot study. In addition, although the survey assessed understanding <strong>of</strong> poverty, future studies using a<br />

validated measure <strong>of</strong> empathy, such as the Jefferson Scale <strong>of</strong> Physician Empathy, need to establish<br />

whether an increased awareness <strong>of</strong> poverty leads to improved empathy.<br />

Utility <strong>of</strong> CT Scan Evaluation for Predicting Pulmonary Hypertension in Patients with Right-Sided<br />

Cardiac Catheterization<br />

Kam, J.C.*, Pi, J., Riar, S., Elnahar, Y., DeBari, V., Klukowicz, A.J., Shamoon, F. and Miller, R.A.<br />

Introduction: Right heart catheterization is currently the gold standard used to detect pulmonary<br />

hypertension (PH) and to grade its severity. However, cardiac catheterization, like any invasive<br />

procedure, is associated with important risks and complications. Computerized topography (CT)<br />

scanning <strong>of</strong> the chest is a non-invasive investigative modality commonly used in the diagnosis and<br />

management <strong>of</strong> patients with pulmonary pathology. The purpose <strong>of</strong> our study is to determine the utility<br />

<strong>of</strong> CT scans for detecting PH in patients who have had right heart catheterization by comparing CTmeasured<br />

main pulmonary artery diameters (MPAD) to right-heart catheterization-determined mean<br />

pulmonary artery pressures (PAP).<br />

Methods: A retrospective review was conducted on 40 patients with left-sided cardiac pathology who<br />

had undergone both right-heart catheterization and CT scanning <strong>of</strong> the chest at St. Michael’s Medical<br />

Centre in Newark, NJ. Patients with catheterized-measured pulmonary artery pressures (PAP) between<br />

25-40mmHg and >40mmHg were identified as having mild-moderate and severe pulmonary<br />

hypertension respectively. Mean pulmonary artery diameter (MPAD) was measured on CT scans at the<br />

widest portion <strong>of</strong> the main pulmonary artery within 3mm <strong>of</strong> the bifurcation. Statistical analyses were<br />

performed using one-way ANOVA followed by Tukey’s test for multiple comparisons and significant<br />

Assessment <strong>of</strong> Proper Sharps Disposal Among Patients with Diabetes Mellitus<br />

Mujtaba Hasnain, md, Jennifer Costello pharmd, Nurlela Gouveia md, Ashish Parikh, md<br />

Department <strong>of</strong> medicine, saint barnabas medical center, livingston nj<br />

Background: A great deal <strong>of</strong> attention is given to proper sharps disposal in both the clinical and hospital<br />

settings, as occupational exposure to blood borne pathogens from accidental injuries is <strong>of</strong> serious<br />

concern. Patient education is necessary to ensure proper sharps disposal in the home environment, in<br />

order to prevent unnecessary injury and exposure to contaminated blood products<br />

Objective: Phase one <strong>of</strong> this three part study was designed to evaluate the level <strong>of</strong> education that<br />

diabetic patients receive regarding proper disposal <strong>of</strong> sharps (needles, lancets) from their prescribing<br />

providers and/or dispensing pharmacists. Phase two evaluated the effect <strong>of</strong> patient education <strong>of</strong> proper<br />

sharps disposal at home.<br />

Methods: An anonymous survey assessing sharps disposal knowledge was administered to all diabetic<br />

patients presenting to the Internal Medicine Faculty Practice from April to June <strong>of</strong> 2010 (phase 1).<br />

Following completion <strong>of</strong> the survey, patients were educated regarding proper disposal <strong>of</strong> their used<br />

diabetic supplies by a clinical pharmacist. Phase 2 <strong>of</strong> the study, conducted between October and<br />

December <strong>of</strong> 2010, re-evaluated proper diabetic sharps disposal following initial education by redistributing<br />

anonymous surveys to all patients. To aid in proper disposal, our practice implemented a<br />

free disposal system for all patients to utilize. Phase 3 <strong>of</strong> the study, in which area practitioners are being<br />

surveyed regarding provision <strong>of</strong> patient education, is currently underway. In addition, educational<br />

materials highlighting safe disposal practices are being mailed to all the patients in our practice.<br />

Results: A total <strong>of</strong> 44 surveys were completed in phase 1 <strong>of</strong> the study. Only 16% <strong>of</strong> patients stated that<br />

they were educated regarding proper diabetic disposal by a healthcare worker, while overwhelming<br />

majority (84%) <strong>of</strong> patients reported being unaware that proper sharps disposal was necessary. Eighty-six<br />

percent <strong>of</strong> patients reported improper disposal <strong>of</strong> diabetic supplies in the regular trash. A total <strong>of</strong> 25<br />

surveys were completed in phase 2 <strong>of</strong> the study; <strong>of</strong> these, 17 patients had also completed the initial<br />

survey in phase 1. All 17 patients (100%) adhered to proper disposal <strong>of</strong> techniques after receipt <strong>of</strong><br />

education. Eighty –four percent <strong>of</strong> patients utilized the free sharps disposal system provided by our<br />

<strong>of</strong>fice.<br />

Conclusion: Diabetic patients are under-educated regarding safe sharps disposal practices. Patient<br />

The Use <strong>of</strong> Orthostasis as an Indicator <strong>of</strong> Volume Status in Heart Failure and its Role in Comparison to<br />

BNP<br />

T.E Waggoner D.O, Hari Om Sharma MD, Rajiv Tayal M.D J E Malinowski PhD, S M Abo D.O.<br />

Introduction: Intro Congestive Heart failure (CHF) is the most common diagnosis for hospitalizations<br />

and the leading reason for readmissions among Medicare patients. The U.S. Healthcare system<br />

continues to be financially taxed regarding diagnostic and therapeutic measures in the managing <strong>of</strong><br />

decompensated CHF. We determined whether the bedside evaluation <strong>of</strong> orthostatic hypotension has<br />

utility in being an inexpensive, easily measurable and accurate guide to the identification <strong>of</strong> a euvolemic<br />

state in the treatment <strong>of</strong> decompensated CHF.<br />

Methods: In this prospective pilot study, enrollment was over a six-month period from a single hospital<br />

in northern New Jersey. Patients =18- years-old were included with decompensated CHF. Patients had to<br />

be able to maintain supine or erect posture for the duration necessary to evaluate orthostatic changes.<br />

Patients had to have plasma creatinine

The Clinical Implications <strong>of</strong> Trusting the Automated QTc<br />

Eric J Berkowitz, MD; Georgia Panagopoulos, PhD; Robert Graham, MD<br />

Introduction: Long QT syndrome is a genetic or acquired condition characterized by a prolonged QT<br />

interval on the surface ECG and is associated with a high risk <strong>of</strong> sudden cardiac death due to ventricular<br />

tachyarrhythmias. Inaccurate measurements can lead to the inappropriate use <strong>of</strong> medications that<br />

would otherwise be avoided. Furthermore, the overwhelming majority <strong>of</strong> house staff rely on the<br />

automated QTc when interpreting ECGs. Our objective was to assess the accuracy <strong>of</strong> the automated<br />

QTc and to evaluate potential clinical implications.<br />

Methods: We evaluated 142 ECGs obtained via MUSE network. 48 normal ECGs met our inclusion<br />

criteria: sinus rhythm, HR440msec for males, >460msec for females. Statistical analysis was done<br />

using the Kappa Coefficient to calculate the degree <strong>of</strong> agreement between the automated and manual<br />

QTc values. In addition, information was obtained on medications ordered on the date <strong>of</strong> the ECG via<br />

Lenox Hill Hospital Sunrise EMR s<strong>of</strong>tware.<br />

Results: There were 23 Males and 25 Females with a mean±SD age <strong>of</strong> 56±16 and mean HR±SD <strong>of</strong> 75±16.<br />

We found 35.4% (17/48) <strong>of</strong> ECGs had an abnormal QTc via manual calculation. Of these 17 ECGs, 6 were<br />

identified as normal via the automated s<strong>of</strong>tware. Of these 6 patients, 4 had received orders for<br />

medications with QT prolonging potential. 6.3%(3/48) <strong>of</strong> the ECGs were found to have a markedly<br />

prolonged QTc value <strong>of</strong> >500msec and 2 <strong>of</strong> these 3 ECGs were not identified on the automated s<strong>of</strong>tware.<br />

In total, 5 <strong>of</strong> these 7 patients were given potentially dangerous medications. The Kappa value was found<br />

to be 0.53 (P < 0.05).<br />

Conclusion: We found a suboptimal degree <strong>of</strong> agreement between automated and manual QTc values,<br />

which may have deleterious clinical implications, especially upon prescribing certain medications. Health<br />

care practitioners ought to manually calculate the QTc as decisions on medications and other therapies<br />

may be compromised.<br />

A Successful PDSA: Improving Compliance With Platelet Transfusion Guidelines<br />

Elena Katz, MD Malgorzata Klek MD, Randy Levine MD, Robert E.Graham MD. Lenox Hill Hospital, New<br />

York, NY.<br />

Introduction: Evidence-based guidelines are developed and promoted to help physicians implement<br />

best practice care. The <strong>American</strong> Society <strong>of</strong> Hematology (ASH) platelet transfusion guidelines changed in<br />

2007 to a prophylactic transfusion threshold <strong>of</strong> 10, 000/µL from the previous 20,000/µL. We conducted<br />

a retrospective analysis to assess how well physicians are complying with the new pr<strong>of</strong>essional<br />

guidelines as well as the older, less stringent criteria to administer platelet transfusions. Subsequently,<br />

we assessed the effect <strong>of</strong> an educational intervention on transfusion practices.<br />

Methods: All patients receiving platelet transfusions over a five-month period from Jan-Feb, and April-<br />

June 2010, admitted to the medical, critical care and cardiac services were reviewed. The medical record<br />

clinical indication was then evaluated against the ASH 2007 “Evidence-Based Platelet Transfusion<br />

Guidelines” (Slichter SJ. Hematology 2007): bleeding and platelets =50, 000/µL, pre-invasive procedure<br />

and platelets =50, 000/µL, prophylactic transfusion for platelets =10, 000/µL and WHO bleeding grade =<br />

2. We also assessed how the patients’ clinical indication met the previous prophylactic threshold for<br />

platelet transfusion <strong>of</strong> =20, 000/µL.<br />

Following initial data collection, we implemented an educational intervention by giving a lecture,<br />

reviewing all indications for platelet transfusions, and distributing a pocket card to the house-staff on<br />

the medical wards in August, 2010. We subsequently gathered post-intervention data following the<br />

methods described above for four consecutive months from Sept-December, 2011. Data analysis was<br />

conducted using a Z-test with a = 0.05 and Z critical value = 1.96.<br />

Results: Eighty-six patients on the selected units received a total <strong>of</strong> 241 platelet transfusions preintervention<br />

and 81 patients received a total <strong>of</strong> 237 platelet transfusions post-intervention. The<br />

patient’s clinical indication met the old guidelines in 63% <strong>of</strong> cases pre-intervention and in 81% <strong>of</strong> cases<br />

post-intervention with a significant p-value <strong>of</strong>

Transtheoretical Model (TTM) Stages <strong>of</strong> Change Related to Diet & Physical Activity Behaviors Among<br />

Inner City Minority with High Prevalence <strong>of</strong> Obesity<br />

Jaxel Lopez Sepulveda, MD Juan Buitrago MD Otto Garay MD Teresa Giraldo MD Maria Ramos Carla<br />

Boutin Foster MD Linda Gerber PhD Balavankatesh Kanna MD MPH1<br />

Introduction: Obesity is a large public health problem in the United States (US). Lack <strong>of</strong> physical activity<br />

(PA) and poor eating choices are major reasons. Nationwide, programs have attempted to tackle obesity<br />

with limited success. According to TTM, health behavioral change occurs in progressive stages from precontemplation,<br />

contemplation, preparation (TTM-ES), to action and maintenance (TTM-AM). This model<br />

helps analyze the readiness <strong>of</strong> individuals to make healthy changes. This study describes a sample <strong>of</strong><br />

minority individuals with respect to their stage <strong>of</strong> change.<br />

Methods: An anonymous survey was conducted in the South Bronx, New York city (NYC) to study the<br />

association <strong>of</strong> TTM stages <strong>of</strong> PA and diet change to obesity. The survey assessed TTM stages, perception,<br />

understanding <strong>of</strong> diet/ PA /weight, and willingness to act. BMI (kg/m 2 ) data were collected. Subjects<br />

who were in TTM –AM stages <strong>of</strong> healthy diet behavior were compared to those who were in early stages<br />

(TTM-ES). Using logistic regression, odds ratios (OR) & 95% confidence intervals (CI) were calculated. A p<br />

value <strong>of</strong> < 0.05 was considered significant.<br />

Results: Of the 800 surveyed, 580 (72.5%) had BMI > 25; 738(92.3%) were Latinos, 485 (60.7%) were<br />

women; 371(46.3%) subjects were in TTM-AM and 359(44.9%) in TTM-ES <strong>of</strong> diet; 378(47.3%) subjects<br />

were in TTM-AM and 388(48.5%) in TTM-ES <strong>of</strong> PA. Subjects in TTM-AM <strong>of</strong> diet were less likely to be<br />

Clinical Risk Assessment Score for Acute Kidney Injury in Patients Admitted to Intensive Care Unit<br />

Rakesh Malhotra, MD MPH Rakesh Malhotra, Etienne Macedo, Josee Bouchard, Jihoon Kim, Lucila<br />

Ohno-Machado, Ravindra Mehta<br />

Introduction: Acute kidney injury (AKI) is a well-recognized complication <strong>of</strong> critical illness encountered in<br />

25-50% <strong>of</strong> ICU admissions and is associated with increased morbidity and mortality. Several studies have<br />

established the relationship between small increments in serum creatinine and adverse events and<br />

suggested that accurate identification <strong>of</strong> individuals at risk and early recognition <strong>of</strong> an AKI episode could<br />

<strong>of</strong>fer opportunities for interventions. Over the past decade, several risk stratification scores have been<br />

developed to predict AKI in specific clinical settings (e.g., after cardiac surgery, contrast exposure,<br />

hospital-acquired, general surgery and high-risk surgery). However, there are relatively few models<br />

examining the clinical risk factors for the development <strong>of</strong> AKI among the intensive care unit (ICU)<br />

population. We hypothesized that a risk stratification score based on routinely available clinical risk<br />

factors would accurately predict AKI risk in an ICU population.<br />

Methods: Our cohort consists <strong>of</strong> 742 patients admitted to medical-surgical ICU in a university hospital<br />

between June 2006 and Dec 2008. Baseline risk factors were ascertained at ICU admission and<br />

additional acute factors within the first 48 hrs <strong>of</strong> ICU stay. Patients were stratified as no risk, baseline<br />

risk, acute risk, and enhanced risk. Incidence <strong>of</strong> AKI, need for renal replacement therapy (RRT) and<br />

mortality were assessed among these risk groups. Separate risk score was developed using<br />

multivariable regression coefficients based on combined baseline and acute risk factors in the training<br />

cohort. Risk Score was further evaluated in a test cohort. The discrimination <strong>of</strong> the scoring model was<br />

examined by the Area Under the Receiver Operating Characteristic Curve (ROC) and the model<br />

calibration was evaluated by Hosmer-Lemeshow test.<br />

Results: The overall incidence <strong>of</strong> AKI was 22.9% (164 cases). Patients classified as enhanced risk had a<br />

higher incidence <strong>of</strong> AKI (31.1% vs. 9.1%; p < 0.001), higher mortality (10.1% vs.0.9%; p< 0.001) and need<br />

for RRT (8.2% vs. 0.0%; p< 0.001) compared to patients with solely baseline risk. In the multivariate<br />

model, chronic kidney disease (CKD), chronic liver disease, congestive heart failure (CHF), hypertension<br />

(HTN), atherosclerotic coronary vascular disease (ASCVD), pH=7.30, nephrotoxin exposure, sepsis,<br />

mechanical ventilation and anemia were identified as independent predictors <strong>of</strong> AKI and the c-statistic<br />

for the model in the test cohort was .792 (.697-.887).<br />

Conclusion: A risk classification system based on chronic comorbidities and acute events can identify ICU<br />

patients at high risk to develop AKI and adverse outcomes within 48 hours <strong>of</strong> ICU admission. This risk<br />

assessment tool could help clinicians to stratify patients for surveillance, prevention and early<br />

therapeutic intervention.<br />

Dept. <strong>of</strong> Medicine, Staten Island University Hospital, NY 2. Nursing Program, Wagner <strong>College</strong>, NY<br />

Introduction: Immunosuppressive regimens improve survival <strong>of</strong> renal transplant recipients (RTR);<br />

however, a long-term complication is increased risk <strong>of</strong> developing cancer. It is predicted that mortality<br />

due to malignancy will exceed cardiovascular casues in the next twenty years. Human papillomavirus<br />

(HPV) associated cancers <strong>of</strong> the genital tract are <strong>of</strong> particular interest, since they are sexually<br />

transmitted and in theory preventable. Cervical cancer rates are high in RTR but the data on the natural<br />

history <strong>of</strong> HPV infection in RTR are limited. Therefore, we investigate HPV and the development <strong>of</strong><br />

cervical neoplasia.<br />

Methods: A review was conducted in Medline database for articles in English investigating cervical HPV<br />

infection in RTR. Eligible studies included those that examined HPV infection by PCR testing and/or<br />

obtained cervical biopsies. Three reviewers extracted the data and compared rates to the general<br />

population.<br />

Results: Out <strong>of</strong> 157 relevant citations, 12 met our inclusion criteria: 4 prospective studies included 231<br />

RTR, 27.27% became HPV (+) and 13.2% that went for biopsy had a high grade dysplasia and 71.43% had<br />

mild dysplasia. Six cross-sectional studies examined 252 RTR, 21.39% were HPV (+) and 19.76% had a<br />

high grade dysplasia and 62.79% had mild dysplasia. Two retrospective studies included 276 patients,<br />

only 25 RTR were sent for biopsy with 32% having high grade dysplasia and 60% had mild dysplasia. The<br />

average duration <strong>of</strong> immunosuppression was 3.1 years to diagnose HPV or dysplasia. (See table below)<br />

Conclusion: Cervical cancer screening guidelines in RTR are not based on published data.<br />

Recommendations in RTR have been extrapolated from the general population. In our study, we<br />

demonstrate in a large cohort <strong>of</strong> RTR that the HPV prevalence is similar to that <strong>of</strong> the general<br />

population. However, the progression rates to high grade dysplasia are several folds higher at an<br />

average duration <strong>of</strong> 3.1 years <strong>of</strong> immunosuppression. 13-32% <strong>of</strong> RTR biopsied had high grade dysplasia<br />

compared to 0.8% in the general population rate and 60 to 71% had mild dysplasia compared to 0.5% in<br />

the general population. The uptake <strong>of</strong> cancer screening is low in RTR , as proved by studies in the<br />

past. Cervical cancer screening and prevention is important in RTR. Counseling should be aimed at<br />

limiting risky sexual behaviors post transplantation.<br />

MPH Vijay Kanakadandi MD Bijal Mehta MD Ethan D Fried MD, MS, MACP<br />

Introduction: The Accreditation Council for Graduate Medical Education (ACGME) implemented<br />

substantial changes to resident duty hours starting July 2011. These have been met with differing levels<br />

<strong>of</strong> agreement on their impact on resident wellbeing and their lives apart from work. The internal<br />

medicine residency program at our institution has been in accordance with the new regulations for the<br />

last 4 years. This study was aimed at assessing the attitudes <strong>of</strong> the residents towards the impact work<br />

hour regulations have on informal teaching by residents and time available for research activities.<br />

Methods: The survey was conducted electronically among the residents <strong>of</strong> a large, urban, communitybased<br />

teaching hospital. All responses were anonymous. Residents provided responses to questions<br />

about post-graduate year (PGY) status, country <strong>of</strong> graduation, demographics and various aspects <strong>of</strong><br />

patient care on medicine floors. Informal teaching included activities that residents undertake to teach<br />

interns and/or medical students outside the scope <strong>of</strong> formal didactic teaching. A Likert type scale with<br />

responses ranging from “Strongly Disagree” to “Strongly Agree” was used to assess the responses. The<br />

responses were quantified numerically and analyzed using Chi-square and Student T-test.<br />

Results: A total <strong>of</strong> 98 residents out <strong>of</strong> 160 completed the survey. We had a response rate <strong>of</strong> 61.3%. Of<br />

the responders 39% were interns; 30.5% were PGY-2 and 30.5% were PGY-3’s. 61% <strong>of</strong> responders were<br />

male and the mean age was 28 years. Fifty-seven percent were international medical graduates (IMG);<br />

34% were US medical graduates (USMG) and 9% were US citizens who graduated from a medical school<br />

outside the US (US-IMG). When PGY-3 residents were asked if the time constraints allowed them<br />

sufficient time to teach their interns, 41% replied in the affirmative. This was significantly different<br />

depending on level <strong>of</strong> residency, with a 70% <strong>of</strong> PGY-3s agreeing compared to 53% <strong>of</strong> PGY-2s (p

Hernandez-Ilizaliturri. Department <strong>of</strong> Medicine, Roswell Park Cancer Institute.<br />

Introduction: Mantle cell lymphoma (MCL) is an aggressive form <strong>of</strong> non-Hodgkin lymphoma (NHL) that<br />

frequently presents with advanced stage disease. The addition <strong>of</strong> Rituximab, a monoclonal anti-CD20<br />

antibody, to high dose chemotherapy regimens <strong>of</strong>ten followed by stem cell transplant has improved<br />

outcomes, but survival still remains low at 3-5 years. Novel agents are needed to improve outcomes in<br />

MCL. Ofatumumab is a fully human anti-CD20 monoclonal antibody directed against a novel epitope on<br />

the CD20 antigen. OFA has been shown to be more potent than RIT against B-NHL cells in pre-clinical<br />

investigations. OFA is FDA approved for the treatment <strong>of</strong> CLL that is fludarabine and alemtuzumab<br />

refractory or with bulky disease resistant to fludarabine and is being investigated in clinical trials in NHL.<br />

In order to characterize the activity <strong>of</strong> Ofatumumab against MCL, we performed pre-clinical<br />

investigations into the activity <strong>of</strong> OFA against MCL cell lines<br />

Methods: We compared the activity <strong>of</strong> rituximab and <strong>of</strong>atumumab in the MCL cell lines Mino, JeKo, REC-<br />

1 and Z-138. The activity <strong>of</strong> RIT and OFA were compared using functional assays including complementmediated<br />

cytotoxicity (CMC) and antibody-dependent cellular cytotoxicity (ADCC) assays. Tumor cells<br />

were labeled with 51 Cr prior to treatment with RIT or OFA at a dose <strong>of</strong> 10ug/mL and peripheral blood<br />

mononuclear cells (ADCC) or human serum (CMC). 51 Cr-release was measured and the percentage <strong>of</strong><br />

lysis calculated. Mean lysis was compared using a t-test.<br />

Results: OFA showed improved activity compared to RIT in complement mediated cytotoxicity assays<br />

using MCL cell lines (Mino: 65.9% vs 0.5% ; JeKo 43.9% vs 13.3% ; REC-1 25.4% vs 4.7% ; Z-138: 56.4% vs<br />

Differences in Hormone Receptor Status by Age group, Race and Ethnicity among Women with<br />

Primary Breast Cancer in an Inner City Teaching Hospital<br />

Aye Myat Myat Saw, MD, Rajnish Khillan MD, Wah Wah Htun MD, Mark Sonnenschine DO<br />

Introduction: Primary breast cancer (BC) is the leading cause <strong>of</strong> death among female cancer patients.<br />

Studies evaluating expression <strong>of</strong> hormonal receptors in different races have had variable results: African<br />

<strong>American</strong> (AA) BC patients mostly have negative estrogen receptor (ER)/progesterone receptor (PR),<br />

whereas Hispanic (H) BC patients had ambiguous results. Asian (A) BC patients had more negative ER/PR<br />

compared to their non-Hispanic white (NHW) counterparts. Age at diagnosis <strong>of</strong> BC can also predict<br />

diverse receptor expression. This retrospective observational pilot study at an inner city teaching<br />

hospital was done to determine differences in hormone receptor status by age group, race and ethnicity<br />

among women with primary BC.<br />

Methods: Patients were identified with ICD-9 diagnosis code <strong>of</strong> primary BC from January 2007 to July<br />

2011. Women with borderline or unknown ER/PR/Her2 neu receptors status were excluded. Patients<br />

were divided into 4 subtypes: ER/PR + Her 2-, ER/PR + Her 2 +, ER/PR - Her 2 +, ER/PR - Her 2-. Because<br />

this was a pilot study, statistical significance was not calculated.<br />

Results: Race/ethnicity <strong>of</strong> the 141 patients meeting study criteria were H 73, AA 23, NHW 35, A 10.<br />

Most women in all groups had invasive ductal carcinoma: H 64%, AA 74%, NHW 67%, and A 75%. 64% <strong>of</strong><br />

women were 59 years old or younger at time <strong>of</strong> diagnosis. Overall, 33% had AJCC Stage I breast cancer<br />

at the time <strong>of</strong> diagnosis, and 33% Stage II, compared to 41% <strong>of</strong> Hispanics with Stage I. Most patients<br />

were positive for ER: H 74%, AA 63%, NHW 64%, and Asian 75%. PR receptor positivity was as follows: H<br />

56%, AA 41%, NHW 61%, and Asian 67%. Her2-neu receptor was positive as follows: H 25%, AA 33%,<br />

NHW 19%, and Asian 60%. 21 patients (15%) had triple receptor negative breast cancers (H 9, NHW 8,<br />

AA 4). Our Hispanic patient population compared with SEER data was as follows: ER/PR +/ Her 2-<br />

subtype 56% vs 50-70% in SEER; ER/PR+Her2+ and ER/PR-Her2+ subtypes 32% vs 10-20%. Our Asian<br />

population had higher Her2 receptor positivity (60 % vs 10-20%). African <strong>American</strong>s had less ER/PR +/<br />

Her 2- subtype, 44% vs 50-60%.<br />

Conclusion: Our population was younger at diagnosis in comparison to the national average <strong>of</strong> 61 years<br />

old. Hispanics were more likely to have AJCC Stage I breast cancer at the time <strong>of</strong> diagnosis. Hispanics<br />

were also more likely to have Her2 + subtypes as compared to SEER data. Larger studies should be done<br />

to further investigate such differences.<br />

HDAC Inhibitor Therapy in CLL: A Closer Look at Classes <strong>of</strong> Inhibition<br />

Hemant Sindhu, MD (Associate), Mohammed I Kafeel, MD, Jen Wang, MD<br />

Introduction: Elevated histone deacetylase (HDAC) enzyme activity have been implicated in the<br />

development <strong>of</strong> cancer, including leukemia and solid tumors. Although there are in vitro and in vivo<br />

studies using HDAC inhibitors (HDACi) in chronic lymphocytic leukemia (CLL), none <strong>of</strong> the studies have<br />

yet pr<strong>of</strong>iled the levels <strong>of</strong> expression <strong>of</strong> various HDAC isoenzymes in CLL. The increased resistance to<br />

belinostat in response to HDAC1 depletion has been reported. Therefore, phenotyping the specific<br />

isoenzyme may be the important in tailoring the treatment <strong>of</strong> CLL by using more specific HDAC<br />

inhibitors.<br />

Methods: Patients were diagnosed as having CLL according to the International Workshop on CLL (IW-<br />

CLL) and the National Cancer Institute–sponsored Working Group on CLL (NCI-WG) criteria. Quantitative<br />

RT-PCR for HDAC isoenzyme were measured in 32 patients with CLL and compared with 17 normal<br />

volunteer controls. ZAP-70, CD38, CD44 also were assayed and correlated to HDAC isoenzyme levels.<br />

Student’s t-tests were employed to compare the difference <strong>of</strong> HDAC values between CLL patients and<br />

controls. Pearson’s X2 test were used to correlate HDAC isoenzyme levels, Rai stage and CD44<br />

expression levels.<br />

Results: The results showed: 1) HDAC isoenzyme levels in CLL were significantly increased in class 1 <strong>of</strong><br />

HDAC 1 and 3, class II <strong>of</strong> 6, 7, 9, 10 and class III <strong>of</strong> SIRT 1 and 6; 2) Higher expression <strong>of</strong> HDAC isoenzyme<br />

levels were found in ZAP-70 positive than ZAP-70 negative patients and CD44 expression levels were<br />

correlated to HDAC isoenzyme expression levels in the majority <strong>of</strong> HDAC classes.<br />

These results suggest: 1) in CLL, elevated HDAC isoenzyme activity is not restricted to one class which is<br />

whydah inhibitor therapy may need to be directed to more than one specific class <strong>of</strong> HDAC; 2) higher<br />

HDAC expression activity may indicate a poor prognosis and more advanced disease stage (through<br />

indirect evidence) since higher values were found in patients with ZAP-70 positive and higher CD 44<br />

expression levels.<br />

Conclusion: We found that in CLL patients, most <strong>of</strong> the HDAC isoenzyme levels including class I, II and III<br />

were increased 2.1 to 4.7 fold. These findings indicate that in CLL patients, the over-expression <strong>of</strong> HDAC<br />

isoenzymes is not restricted to one class and this may partly explain the reasons for the poor response<br />

<strong>of</strong> the compound MGCD0103 (an orally available class I and class IV HDAC inhibitor) in a Phase II study.<br />

Since HDAC inhibitors have not only chromatin modulating effects but also have other tumor inhibiting<br />

effects, it may be necessary, in future tirals, to use HDAC inhibitors having pan-inhibition <strong>of</strong> HDAC<br />

isoenzymes rather than one specific class.<br />

Introduction: Routine blood tests are usually performed during the early morning hours at hospitals<br />

across the country. Timely review <strong>of</strong> those laboratory tests during morning rounds is critical for safe and<br />

efficient patient care. However, availability <strong>of</strong> those results for rounds is variable. At our institution,<br />

both the batched approach <strong>of</strong> morning blood specimens and high demands for early test results<br />

availability resulted in a heavy workload for laboratory and nursing staff. To explore possible solutions to<br />

this problem, an interdisciplinary group comprised <strong>of</strong> medical, nursing, and laboratory staff assessed the<br />

feasibility <strong>of</strong> routine midnight versus morning (6AM) blood draws.<br />

Methods: Patient preference for midnight or morning blood draws was assessed using a questionnaire.<br />

The chi-square test was used to compare survey results with a random distribution. Routine laboratory<br />

tests were ordered at midnight from August 16 – 31, 2011 on one medicine floor. All 6AM and midnight<br />

orders <strong>of</strong> complete blood cell counts and basic/comprehensive metabolic panels on the study floor were<br />

analyzed. A house staff survey was also conducted after the study period.<br />

Results: A patient survey (N=100) revealed 41 patients preferred midnight blood draws, 22 preferred<br />

main cardiac pumping chamber. LVH can be in response to chronic volume or pressure overload.<br />

Objective <strong>of</strong> this study was to compare the different electrocardiographic criteria for diagnosis <strong>of</strong> severe<br />

LVH.<br />

Methods: Electrocardiographic criteria used for calculating LVH were Sokolow-Lyon criteria, Cornell<br />

voltage index and Romhilt-Estes point score system. A total <strong>of</strong> 71 patients (37 men and 34 women) with<br />

documented LVH on echocardiogram (By ASE criteria) and EKG were selected. All the patients with<br />

bundle branch blocks, WPW syndrome and Atrial Fibrillation on EKG were excluded. 80 % <strong>of</strong> the patients<br />

in the study had hypertension. 13 out <strong>of</strong> 71 patients had severe LVH on echocardiogram and 58 had non<br />

severe LVH. Electrocardiographic criteria including Sokolow-Lyon, Cornell and Romhilt-Estes indices<br />

were determined in all patients. Positive and negative predicitive values for each electrocardiographic<br />

criterion and their combinations were calculated. Logistic regression analysis including clinical variables<br />

such as age, sex, weight and hypertension was performed to ascertain the predictors <strong>of</strong> LVH for all<br />

electrocardiographic criteria. Mean age <strong>of</strong> the patients included in the study was 62.41 years (SD 14.22).<br />

Mean weight was 80.5 kg (SD 17.23).<br />

Results: The proportion <strong>of</strong> patients with severe LVH on echocardiogram was 18% (n=13) in this study.<br />

The positive predictive value for severe LVH was 13%, 24% and 14% by using Sokolow-Lyon, Cornell and<br />

Romhilt-Estes criteria respectively.<br />

Combination <strong>of</strong> these criteria did not increase the performance <strong>of</strong> the test. Cornell voltage index had the<br />

highest negative predictive value (90%) for severe LVH and it was an independent predictor <strong>of</strong> severe<br />

LVH. Negative predictive values for Sokolow-Lyon and Romhilt-Estes criteria were 61% and 67%<br />

respectively.<br />

Conclusion: Cornell voltage index was found to have best negative predictive value among all the three<br />

EKG criteria. Among the electrocardiographic criteria for LVH, Cornell voltage index may be the most<br />

useful to exclude severe LVH.<br />

Induction Of Cytochrome P450 3A4-dependent Vitamin D3 Metabolism And Altered Mineral<br />

Homeostasis<br />

Xi Zheng MD,PhD 1 2, Paul Mustacchia MD 2, Kenneth Thummel PhD 1* 1 Department <strong>of</strong><br />

Pharmaceutics, University <strong>of</strong> Washington, WA 2 Department <strong>of</strong> Medicine, Nassau University Medical<br />

Center, East Meadow, NY<br />

Introduction: Vitamin D3 is critical for the regulation <strong>of</strong> calcium and phosphate homeostasis. Long-term<br />

treatment with certain drugs (e.g. rifampin, phenobarbital, carbamazepine) has been reported to cause<br />

drug-induced osteomalacia. Many <strong>of</strong> these drugs are well-known inducers <strong>of</strong> cytochrome P450 3A4<br />

(CYP3A4). Recently we reported that catalytic activity <strong>of</strong> CYP3A4 towards 1,25(OH)2D3 and 25OHD3, to<br />

form 24R,25(OH)2D3 and 4b,25(OH)2D3 respectively, which might contribute to vitamin D inactivation.<br />

The aim <strong>of</strong> this pilot study is to investigate the effect <strong>of</strong> short-term rifampin therapy on vitamin D<br />

metabolism and mineral homeostasis.<br />

Methods: A total <strong>of</strong> six healthy volunteers were recruited and completed the study. Each received 7<br />

days <strong>of</strong> rifampin treatment (600 mg/day). Multiple blood samples and random urine were collected pre-<br />

and post-treatment. 1,25(OH)2D3, 24R,25(OH)2D3, 4b,25(OH)2D3, 25OHD3, calcium and phosphate in<br />

blood, as well as calcium, phosphate and creatinine in urine, were measured using LC/MS/MS or<br />

standard clinical laboratory procedures. Similarly, in vitro the human intestinal cell line, LS180, and<br />

human hepatocytes were treated with rifampin or rifampin + DHB (a selective CYP3A4 inhibitor).<br />

Vitamin D receptor (VDR)-targeted gene expression and formation <strong>of</strong> vitamin D metabolites were<br />

measured. Statistical comparison <strong>of</strong> the pre- vs post- treatment measurements were conducted with<br />

SAS.<br />

Results: In humans, rifampin treatment caused reductions in the concentrations <strong>of</strong> 25OHD3 (-11%, p <<br />

0.05) and 24R,25(OH)2D3 (-13%, p < 0.05), but had insignificant effect in the 1,25(OH)2D3 level (-10%,<br />

p=0.07). In contrast, there was a significant 2-fold increase in the plasma 4b,25(OH)2D3. Interestingly,<br />

decreased serum calcium were observed in all subjects. Serum calcium and phosphate were significantly<br />

decreased by 1.9% (9.27 vs 9.36 mg/dL, p = 0.004) and by 5% (3.75 vs 3.96 mg/dL, p = 0.01),<br />

respectively. In the urine, the creatinine-normalized phosphate excretion (UPi/UCr), increased by 50%<br />

(0.18 vs 0.26, p = 0.04). In vitro, in human intestinal cell line LS180, rifampin treatment significantly<br />

decreased vitamin D-mediated stimulation <strong>of</strong> TRPV6 expression, which is considered as a gatekeeper<br />

for intestinal calcium absorption. In human hepatocytes, treatment with rifampin led to a 8-fold<br />

increase in 4b,25(OH)2D3 formation, but no change in 24R,25(OH)2D3. Lastly, these in vitro effects <strong>of</strong><br />

rifampin were reversed by addition <strong>of</strong> DHB, which is a selective CYP3A4 inhibitor and an active<br />

ingredient in grapefruit juice.<br />

Conclusion: Short-term treatment <strong>of</strong> rifampin in humans selectively induced CYP3A4-dependent vitamin<br />

D metabolism and altered mineral homeostasis. Together with the in vitro results, this study suggests<br />

that induction <strong>of</strong> CYP3A4 could lead to reduction in oral calcium absorption and stimulation in renal<br />

115


excretion <strong>of</strong> phosphate. If these effects persist in a long term, it could cause drug-induced osteomalacia.<br />

Grapefruit juice, containing DHB, a potent CYP3A4 inhibitor, could potentially prevent drug-induced<br />

osteomalacia/vitamin D deficiency.<br />

Dietary Supplements Among Division I <strong>College</strong> Athletes in New York<br />

Padavan, D. MD Lenox Hill Hospital, Padavan, Sa. MD Mount Sinai Hospital, Graham, R. MD Lenox Hill<br />

Hospital<br />

Introduction: Athletes use supplements including vitamins in hopes <strong>of</strong> improving their athletic<br />

performance, yet there is insufficient research to support their use. The purpose <strong>of</strong> this study was to<br />

document the use <strong>of</strong> supplements in Division I college athletes in New York, reasons for use, if they are<br />

influenced by diet, the doses used and gender differences.<br />

Methods: Seventy-four athletes from two Division I schools were surveyed while undergoing pre-<br />

participation physicals at Lenox Hill Hospital from August 2010 to October 2010. They were given an<br />

anonymous questionnaire developed by the authors. The response rate <strong>of</strong> the questionnaire was<br />

approximately eighty percent (Fifty-nine athletes).<br />

Results: Forty-four females and fourteen males participated in the study (one participant did not<br />

identify their gender). The average age was 19.78 and these athletes competed in basketball, soccer,<br />

golf, tennis, water polo, swimming, lacrosse and track. Thirty-nine percent <strong>of</strong> the athletes admitted to<br />

taking vitamins (45.4% <strong>of</strong> the female athletes, 21.4% <strong>of</strong> the male athletes) with multivitamins, vitamin C,<br />

and biotin being the most consumed (20%, 19%, and 5% respectively). Approximately fourteen percent<br />

<strong>of</strong> athletes took supplements other than vitamins (15.9% <strong>of</strong> the female athletes and 7.1% <strong>of</strong> the male<br />

athletes) with fish oil being the most consumed followed by creatine (5% and 3% <strong>of</strong> all athletes<br />

respectively). Ten percent <strong>of</strong> athletes took both vitamins and other supplements together and they were<br />

all female. There were three vegetarian female athletes and all <strong>of</strong> them took vitamins. The most<br />

common reasons for taking supplements other than vitamins were to supplement diet (4 out <strong>of</strong> 8<br />

athletes) followed by delay fatigue, improve immunity and build muscle (3 out <strong>of</strong> 8 athletes for each).<br />

The doses <strong>of</strong> the supplements consumed were only known by two athletes.<br />

Conclusion: Nearly half <strong>of</strong> Division I college athletes surveyed take supplements and most are unaware<br />

<strong>of</strong> the dosages they consume. There may be a dietary influence on their use. This study suggests the<br />

need for health care pr<strong>of</strong>essionals to screen athletes on the use <strong>of</strong> supplements and educate them<br />

regarding their potential risks and benefits.<br />

Gout Risk Factors and Treatment among Chronic Kidney Disease Patients: A Hospital Based Cross<br />

Sectional Study<br />

Yun Xia, MD, Yanli Fan, MD, David Gemmel, PhD, Erdal Sarac, MD<br />

Introduction: Gout has doubled in prevalence in the United States. Recent studies have proposed<br />

hyperuricemia and gout as risk factors for progression <strong>of</strong> chronic kidney disease (CKD). This study<br />

investigated the prevalence <strong>of</strong> gout in patients with CKD and compared the current practice patterns to<br />

recommendations and guidelines put forward by the European League Against Rheumatism (EULAR).<br />

Methods: A total <strong>of</strong> 1,827 patients admitted between 2009 and 2010 at St. Elizabeth Health Center with<br />

a diagnosis <strong>of</strong> chronic kidney disease were included by database search using ICD-9 codes. Patients were<br />

divided into two groups: CKD with gout and CKD without gout. Data collection included age, sex, and<br />

comorbid diagnoses. A subset <strong>of</strong> 50 patients was randomly selected to compare the treatment they<br />

received with EULAR guidelines.<br />

Results: The prevalence <strong>of</strong> gout in the hospitalized patients with CKD was 251/1827 (13.7%, 95% CI 12-<br />

15%). Males exhibited higher rates <strong>of</strong> gout: 150/964 (15.6%) vs. 101/863 (11.7%), respectively (X2=5.40,<br />

p=0.02). Gout prevalence increased with age - highest prevalence was observed among patients age 71<br />

to 80 years, with elderly males exhibiting even higher rates <strong>of</strong> disorder (17% in female and 26% in male).<br />

CKD patients with and without gout has a prevalence rate <strong>of</strong> coronary artery disease <strong>of</strong> 41.8% vs. 36.3%<br />

(X2=2.62, p=0.11). Both hyperlipidemia and diabetes mellitus were higher in the CKD patients with gout:<br />

46.2% versus 38.7% (X2=4.71, p=0.03), and 29.8% versus 23.8% (X2=3.99, p=0.04). Hypertension was<br />

higher in patients with gout, 82.5% versus 78.1% (X2=2.20, p=0.14). Only 65% <strong>of</strong> CKD patients with gout<br />

were treated following The European League Against Rheumatism (EULAR) guidelines.<br />

Conclusion: This study reveals a high prevalence <strong>of</strong> gout in patients with CKD. Male sex, advanced age,<br />

diabetes, and hyperlipidemia were significantly associated with gout among CKD patients. Treatment for<br />

gout was sub-optimal in the subset <strong>of</strong> examined CKD patients. Allopurinol, a traditional treatment for<br />

gout, which has dosing restrictions for renal impairment, may explain this finding. Newer treatment<br />

modalities for gout may change these findings in the future. Greater awareness is needed to improve<br />

the management strategies for gout in CKD patients.<br />

Introduction: Carbon monoxide (CO) is the most common cause <strong>of</strong> death from poisoning in the United<br />

States. Cardiovascular complications and their contribution to acute outcomes are yet to be defined.<br />

Methods: We retrospectively reviewed all the cardiovascular manifestations <strong>of</strong> CO poisoning in patients<br />

presented to St Vincent Charity Medical Center, the regional center for CO poisoning treatment<br />

between the periods <strong>of</strong> January 2009 to September 2011. Patients demographics, comorbidities,<br />

electrocardiograms (EKG), laboratory results and echocardiograms were identified from chart review<br />

and retrieved for analysis.<br />

Results: We identified 47 patients, mean age 49.3 years and majority were male (72%). The mean<br />

hospital stay was 2.6 days. The average carboxyhemoglobin (COHb) level was 24.9%. 20% <strong>of</strong> cases were<br />

intentional poisoning, 19% were unconscious on presentation (UOP) and 20% were<br />

intubated. Cardiovascular risk factors in these patients were diabetes mellitus 9%, hypertension (HTN)<br />

36%, dyslipidemia 6%, smoking 32% and family history <strong>of</strong> premature coronary artery disease 4%.<br />

Obesity was present in 19% with 4% having documented history <strong>of</strong> CAD and 14% with cocaine abuse<br />

prior to admission. Troponin I was found to be greater than 0.2 ng/mL in 37 % <strong>of</strong> patients and more than<br />

1 ng/mL in 17%. Ischemic EKG changes were found in 4 % <strong>of</strong> patients. Corrected QT interval (QTc) was<br />

prolonged (>440 msec) in 68% <strong>of</strong> patients. Echocardiogram was done in 9% <strong>of</strong> patients and 4% had<br />

depressed left ventricular ejection fraction which recovered after hyperbaric oxygen treatment. 92% <strong>of</strong><br />

patients received treatment with hyperbaric oxygen (HBO). Two patients died by anoxic brain injury<br />

that was unrelated to their cardiac status. There was no correlation between COHb level and troponin<br />

or QTc (r = -0.2 and 0.02 respectively). UOP and intubation were the main predictors <strong>of</strong> significant<br />

myocardial injury with 55.5% <strong>of</strong> UOP group (P=0.002) and 62.5% 0f intubated patients having a troponin<br />

I > 1 ng/mL (P=0.001). HTN was the only predictor <strong>of</strong> significant QTc prolongation with 88% <strong>of</strong><br />

hypertensive group having a QTc >440 msec (P=0.016).<br />

Conclusion: Myocardial damage in patients presenting with CO poisoning is common and manifested by<br />

increased troponins and prolonged QTc. There is no correlation between COHb level and myocardial<br />

injury. In these patients, UOP and intubation are the only two significant predictors <strong>of</strong> troponins<br />

elevation while HTN is associated with more QTc prolongation. This damage is usually transient and is<br />

reversed with urgent HBO therapy.<br />

The IL-2 Levels in Supernatants <strong>of</strong> Intra-Epithelial Mucosal Lymphocytes Stimulated in Vitro with Anti-<br />

CD3 were Significantly Higher in Healthy Adults Compared to the Patients with Inflammatory Bowel<br />

Disease (IBD).<br />

Ali Raza, MD. Shata, Mohamed Tarek Ahmed, Kashif Navaneethan, Udayakumar Abdel-Hameed, Enass<br />

Giannella, Ralph A.<br />

Introduction: Inflammatory Bowel Disease (IBD) is characterized by an unusual and exacerbated<br />

immune response in gastrointestinal (GI) tract. Intestinal inflammation results from shift <strong>of</strong> balance<br />

away from immunosuppressive responses. Recently, role <strong>of</strong> newly discovered T-helper cells have been<br />

described in the pathogenesis <strong>of</strong> IBD. Of these, T-regulatory (T-reg) cells and T-helper 17 (Th-17) cells<br />

have been the focus <strong>of</strong> attention due to their immunosuppressive and proinflammatory properties<br />

respectively. IL-2, produced by various lymphocytes, is a potent stimulator <strong>of</strong> the T-reg cells. Animal<br />

models have demonstrated significant intestinal inflammation in IL-2 deficient hosts. Similarly, blocking<br />

IL-2 results in enteritis in mice. Our study objective is to compare the IL-2 levels in plasma and the intraepithelial<br />

mucosal lymphocytes in healthy adults and IBD patients.<br />

Methods: In our on-going prospective cohort study, we have enrolled 10 patients with either Ulcerative<br />

Colitis (UC) or Crohn’s Disease (CD) and 13 healthy controls. We measured the plasma levels <strong>of</strong> IL-2 in all<br />

the IBD patients and healthy controls using ELISA assays according to the manufacturer’s instructions.<br />

Similarly, IL-2 levels were measured in the supernatant <strong>of</strong> intra-epithelial lymphocytes (IEL) isolated<br />

from rectal biopsy from all IBD patients and controls after in vitro stimulation with anti-CD3 for 48<br />

hours.<br />

Results: Plasma levels <strong>of</strong> IL-2 were compared in healthy controls (Mean= 1.099 pg/ml) and IBD patients<br />

(Mean= 1.14 pg/ml) using Wilcoxon 2 sample test, which did not show any significant difference (Pvalue=<br />

0.9766). The IL-2 levels in the supernatant <strong>of</strong> stimulated IEL in controls (Mean= 1440.91 pg/ml)<br />

and IBD patients (Mean= 76.82 pg/ml) were compared using the same test, which showed significantly<br />

higher levels in controls compared to IBD patients (p-value= 0.006).<br />

Conclusion: Mucosal epithelial levels <strong>of</strong> IL-2 were significantly higher in healthy controls compared to<br />

IBD patients upon T cell stimulation. IL-2 may suppress the proinflammatory responses by stimulating Treg<br />

cells growth and function. This makes IL-2 an important therapeutic target for future biological<br />

agents.<br />

The Association Between Free PSA Velocity and Prostate Cancer Diagnosis by Biopsy<br />

Shoshana Jo Weiner, MD Jianbo Li, PhD Osama Zaytoun, MD Stephen Jones, MD<br />

Introduction: Screening for prostate cancer with total serum prostate specific antigen (PSA) has not<br />

been shown to improve the mortality <strong>of</strong> prostate cancer patients. This has led to a search for new<br />

biomarkers. To date, no one has evaluated the relationship <strong>of</strong> free PSA (fPSA) velocity, the change in the<br />

concentration unbound serum PSA over time, to prostate cancer diagnosis.<br />

Methods: All patients who presented to the Cleveland Clinic between 2000 and 2009 who had at least<br />

two prostate biopsies, with one negative biopsy, were considered for the study. A case-control study<br />

was conducted to compare free PSA velocity between cases, who are patients diagnosed with prostate<br />

cancer (Gleason score > 0) after a previously negative biopsy, and controls, who are patients with two<br />

sequential negative biopsies. Univariate analyses were conducted to compare absolute differences and<br />

velocities <strong>of</strong> fPSA and PSA between cases and controls. Age, race, prostate volume, positive digital<br />

rectal exam and the pathological features <strong>of</strong> prostatic intraepithelial neoplasia (PIN), atypia and<br />

inflammation were compared between cases and controls for each biopsy. An iterative logistic<br />

regression model was constructed in order to compare fPSA velocity between cases and controls. All<br />

statistics were considered significant at a p-value <strong>of</strong> 0.004 with the application <strong>of</strong> the Bonferroni<br />

correction.<br />

Results: Forty-nine cases and 128 controls had the necessary fPSA values, which were restricted to being<br />

within two months <strong>of</strong> each biopsy. In addition, all biopsies required at least 10 cores and needed to be<br />

at a minimum one year apart from the previous biopsy. Our population was mainly Caucasian<br />

(86%). The median ages for the first and second biopsies were 62 (IQR: 56, 67) and 64 (IQR: 58, 69),<br />

respectively. 9 (18%) <strong>of</strong> the positive biopsies had a Gleason score <strong>of</strong> 7 or greater, and most were<br />

Gleason score 6 (78%). There was no significant difference in the fPSA velocity between cases (-0.21,<br />

IQR: -2.32, 1.06) and controls (0, IQR: -1.73, 0.81). For the second biopsy, samples from cases had<br />

significantly more PIN (49% versus 26%,p-value= 0.003) than controls, and controls had significantly<br />

more inflammation (69% versus 43%, p-value= 0.002). fPSA velocity was not significantly associated<br />

with having a positive prostate cancer biopsy in the logistic regression model (Odd ratio: 0.92; 95% CI<br />

0.75-1.12), which adjusted fPSA for PSA velocity and absolute change in PSA.<br />

Conclusion: fPSA velocity is not associated with a positive prostate biopsy for cancer. This may be due<br />

to confounding pathological findings on biopsy such as inflammation.<br />

Drug Screen Pr<strong>of</strong>ile <strong>of</strong> Patients on Chronic Pain Medications.<br />

Howard Y Lee, DO Lyn Rojas, MD William Yarborough, MD<br />

Introduction: Narcotics are used extensively for chronic pain management in the United States. Opioid<br />

misuse occur frequently in chronic pain patients in a pain management program within an academic<br />

primary care practice. Narcotic abuse has been demonstrated in 9% to 41% <strong>of</strong> patients receiving chronic<br />

pain management. Illicit drug use has been reported in 14% to 34% <strong>of</strong> patients in chronic pain<br />

management settings. Structured monitoring for opioid misuse appears to be one <strong>of</strong> the important<br />

aspects <strong>of</strong> effective pain management. Narcotic contracts have been used to help ensure compliance,<br />

but there is limited empirical evidence for the effectiveness <strong>of</strong> opioid contracts. We propose to<br />

determine the drug screen pr<strong>of</strong>ile and determine incidence <strong>of</strong> illicit drug use in patients on chronic pain<br />

management with the University <strong>of</strong> Oklahoma (OU) in Tulsa Internal Medicine Clinic.<br />

Methods:The records <strong>of</strong> all adult patients on chronic pain management with a diagnosis <strong>of</strong> back pain<br />

that have a narcotic contract with OU Internal Medicine seen in the clinic between June 1, 2010 and<br />

May 31, 2011 were reviewed. Each chart was checked whether the patient had a urine drug screen. In<br />

those patients who have had a drug screen, we checked if the result was consistent with their<br />

medication pr<strong>of</strong>ile. It was also checked for presence <strong>of</strong> illicit substances. The prevalence <strong>of</strong> drug abuse<br />

was then obtained.<br />

Results: In the scheduled time duration, eight hundred sixty four patients were seen in the clinic for<br />

back pain medication refill. One hundred nineteen (119/864) patients had urine drug screen. Sixty four<br />

(64/119) patients had inconsistent drug screen. Of the sixty four patients who had inconsistent drug<br />

screen, twenty six patients (26/64) were positive for marijuana, (2/64) two patients were positive for<br />

methamphetamine, (2/64) two were positive for both marijuana and methamphetamine, and one<br />

(1/64) was positive for cocaine.<br />

Conclusion: Majority <strong>of</strong> patients on chronic pain management never had a urine drug screen. There is a<br />

prevalence <strong>of</strong> fifty four percent for inconsistent drug screens and twenty six percent for illicit drug use in<br />

patients on chronic pain management in spite <strong>of</strong> having a narcotic contract. It is suggested that drug<br />

screening should be done periodically on these patients.<br />

Smokers on a Fixed Income: Understanding the Long Term Health and Financial Consequences <strong>of</strong><br />

Smoking<br />

Jason Shultz MD (Associate); Martina Jelley MD FACP<br />

Introduction: Smoking is the number one cause <strong>of</strong> preventable death in the United States and<br />

worldwide. Approximately 440,000 <strong>American</strong>s and 5 million people worldwide will die each year from<br />

smoking related illnesses. The long term adverse health effects <strong>of</strong> smoking are very well publicized, yet<br />

a significant proportion <strong>of</strong> <strong>American</strong>s still smoke and every year millions more begin smoking for the first<br />

time. Prior studies have shown that financial incentives for smoking cessation significantly increased<br />

the the rates <strong>of</strong> smoking cessation.<br />

Methods: Internal medicine clinic and hospital patients identified as current smokers were surveyed<br />

regarding their smoking history and financial status. Only patients who were living on a fixed income<br />

were included. Each patient was questioned regarding their understanding <strong>of</strong> the adverse health risks<br />

followed by questions related to the amount <strong>of</strong> money spent on cigarettes. Finally, each participant was<br />

asked a question to estimate the amount <strong>of</strong> money an average smoker would accumulate should they<br />

invest their money over the course <strong>of</strong> their smoking life versus spending it on cigarettes.<br />

Results: A total <strong>of</strong> 25 patients were identified and completed the survey. It was determined that all <strong>of</strong><br />

the participants demonstrated a sufficient understanding <strong>of</strong> the long term health adverse effects<br />

associated with smoking such as cancer, heart disease, stroke and lung disease. However, patients<br />

significantly underestimated the cumulative wealth potential had they invested the money they spent<br />

on cigarettes instead. On average, the respondents underestimated this figure by $492,970.<br />

Additionally, the average smoker surveyed spent nearly 20% <strong>of</strong> their total monthly income on cigarettes<br />

and had reported virtually no savings.<br />

Conclusion: The findings <strong>of</strong> this survey suggest that smokers who live on a fixed income have a limited<br />

understanding <strong>of</strong> the true long term financial consequences <strong>of</strong> their smoking habit. As demonstrated in<br />

prior studies, people <strong>of</strong>ten respond to financial incentives to quit smoking. Perhaps, an increased<br />

awareness <strong>of</strong> the true financial impact <strong>of</strong> smoking on one’s personal wealth would help improve<br />

smoking cessation and prevention efforts. Since almost 60% <strong>of</strong> new smokers are under the age <strong>of</strong> 18, a<br />

shift to increase emphasis on the long term financial impact in addition to adverse health effects may be<br />

more effective.<br />

Introduction: Diabetes mellitus (DM) was the seventh leading cause <strong>of</strong> death in 2006. The number <strong>of</strong><br />

patients is expected to double by 2050. Simple non-adherence to follow guidelines by physicians is a<br />

significant source <strong>of</strong> morbidity and mortality. Our goal was to study the impact <strong>of</strong> an electronic template<br />

on adherence to follow ADA guidelines for diabetes care by general internist.<br />

Methods: We designed an electronic template based on the 8 point ADA guidelines for management <strong>of</strong><br />

,MD,FACC, Faisal Latif,MD,FACC, & Udho Thadani, MD,FRCP, FACC, FAHA<br />

Background: Aggressive risk factor control and evidence based medical therapy is recommended for<br />

treating patients with coronary artery disease (CAD). While it is assumed that obstructive CAD (OCAD)<br />

patients usually achieve such targets, data in non-obstructive (NOCAD) CAD patients is scant. We<br />

compared risk factor control and use <strong>of</strong> evidence based medical therapy in patients with NOCAD and<br />

OCAD.<br />

Methods: Patients who had undergone coronary angiography, between January 2006- June 2006 at the<br />

Oklahoma City VA Medical Center, and in whom one year follow-up data was available, were included.<br />

Demographic, clinical, laboratory and medical treatment data were compared between NOCAD & OCAD<br />

groups at baseline and 1 year. Non-parametric Wilcoxon Sum rank test was used to compare means and<br />

chi-square tests for comparing proportions, at a significance level <strong>of</strong> 0.05.<br />

Malaria Prevention in Informal Settlements: Is There a Role for Mosquito Coils?<br />

Jonathan Rogers, MD<br />

Introduction: Nairobi is considered a low risk area for malaria transmission (CDC, 2011), likely due to<br />

high altitude and urban land use. However, malaria ranked as the second highest contributor to<br />

outpatient morbidity in Nairobi, accounting for 10.6% <strong>of</strong> acute illnesses. The burden is estimated to be<br />

even higher in informal settlements. Prior surveys revealed an unmet need for malaria prevention in<br />

Nairobi. Thus, to identify preventive measures associated with a decreased risk <strong>of</strong> malaria in informal<br />

settlements, we conducted a case control study in Nairobi, Kenya.<br />

Methods: During April <strong>of</strong> 2009, cases were identified from clinic patients presenting with malaria in<br />

Nairobi’s Kawangware settlement. P. falciparum parasitemia was confirmed by lab technician by<br />

microscopic examination <strong>of</strong> blood smears. As a comparison group, patients presenting for routine health<br />

maintenance were surveyed. Those patients presenting with symptoms suggesting infection were<br />

excluded, unless they had a negative blood smear. The survey contained questions on demographics,<br />

malaria prevention, exposure history, and sanitation. This was provided in English, Swahili, and verbally<br />

for illiterate patients. To identify key covariates associated with a risk <strong>of</strong> malaria, univariate analysis was<br />

used to calculate Pearson’s chi square p value (SPSS). For multivariate analysis, logistic regression was<br />

performed to adjust for age and sex.<br />

Results: During the study period, 45 cases and 68 controls were surveyed. Eight controls and zero cases<br />

refused. Baseline demographic characteristics differed significantly as cases had a much higher<br />

proportion in 0-19 age group (56% versus 27%, p value=0.003), but sex and tribe were not significantly<br />

different. Use <strong>of</strong> mosquito coils differed significantly, used by 18% <strong>of</strong> cases and 42% <strong>of</strong> controls (odds<br />

ratio 0.31, p=0.01), and remained significant after accounting for age and sex (p=0.03). Proximity to<br />

stagnant water, such as open buckets, public toilets, irrigation systems, was also significantly associated<br />

with malaria positivity by univariate analysis. Insecticide treated nets were not significantly associated,<br />

although there was a trend for reduced risk with an odd’s ratio <strong>of</strong> 0.65 (confidence interval 0.29-1.45).<br />

Conclusion: These results demonstrate an association between mosquito coil use and malaria risk.<br />

Mosquito coils have been shown to reduce insect bites through repellent effect, but there are no<br />

prospective randomized trials assessing the relationship with malaria transmission. Observational<br />

studies on coils have thus far demonstrated mixed results. Insecticide treated nets were not associated<br />

with decreased risk, but it is possible that respondents were not re-applying insecticide on old nets<br />

depleted <strong>of</strong> the chemical repellents. Limitations to this study include small sample size, potential for<br />

recall bias due to study design, and inability to generalize to populations not residing in informal<br />

settlements. Additionally, this association does not demonstrate causality as coil use may be a general<br />

marker <strong>of</strong> health seeking behavior. Mosquito coils may be useful low cost adjunct to insecticide treated<br />

nets, but randomized controlled trials should be considered to prove efficacy.<br />

Santamore, Alfred A. Bove<br />

Introduction: Patients at increased risk for cardiovascular disease not only benefit from standard<br />

pharmacotherapy, but also physician counseling regarding life-style behavioral changes such as weight<br />

loss and exercise. This study sought to examine the patient factors that influence physicians' provision <strong>of</strong><br />

nutrition and exercise counseling among individuals at increased risk for CVD.<br />

Methods: This was a secondary analysis <strong>of</strong> a telemedicine trial among an underserved inner-city and<br />

rural population (n=388) with a 10% or greater CVD risk (Framingham 10 year risk score). Subjects were<br />

followed for one year and were seen for quarterly assessments, which included evaluation <strong>of</strong> weight,<br />

BP, lipid, and glucose status. At each <strong>of</strong> the four quarterly visits, subjects were asked if their physician<br />

had discussed or made recommendations regarding life-style behaviors, specifically diet/weight loss and<br />

exercise.<br />

Results: The average age <strong>of</strong> subjects was 60.9 +/- 9.7 years and mean BMI was 31.6 +/- 7 kg/m2. CVD<br />

risk decreased by 2.5% over the one year <strong>of</strong> follow-up (17.5 +-10.3% at baseline vs. 15 +/- 9.3% at 1 year,<br />

Early Intravenous (IV) to Oral (PO) Azithromycin Conversion in Hospitalized Patients with Community<br />

Acquired Pneumonia (CAP).<br />

Julian Diaz-Fraga, MD; Archana Satyal-Chaudhary, MD; Andrew Crocker, MD; Shuchi Gulati, MD; Gaurav<br />

Gulati, MD; Anup Subedee, MD; David George, MD.<br />

Introduction: Many patients admitted with community-acquired pneumonia (CAP) continue to receive<br />

IV antibiotics for longer than necessary. Early conversion from IV to PO route has been reported to<br />

increase patient safety and comfort, reduce cost, and facilitate earlier discharge, without compromising<br />

medical care. We developed an intervention strategy to decrease the time from IV to PO conversion <strong>of</strong><br />

azithromycin therapy for CAP in hospitalized patients by 20% over a 3 month period.<br />

Methods: This resident-led quality improvement project was conducted in a 750-bed community<br />

teaching hospital in which all medications are ordered online. We created a radio button option added<br />

to electronic CAP order set to allow physicians to preauthorize pharmacists to convert IV to PO<br />

azithromycin for patients meeting certain criteria. Hospitalist and resident staff received real time<br />

feedback to reinforce education and address variation in practice patterns. Pharmacy developed a<br />

system <strong>of</strong> rapid identification <strong>of</strong> candidates for antibiotic conversion. Pre- and post-intervention<br />

measures included time to conversion from IV to PO antibiotic dosing, length <strong>of</strong> stay, rates <strong>of</strong><br />

readmission, death, transfer to a higher level <strong>of</strong> care, and reconversion to IV antibiotic therapy. Baseline<br />

and final statistics were collected via electronic health record (EHR) chart review.<br />

Results: The average time from IV to PO azithromycin conversion was decreased by more than 50% (1 ½<br />

days) after our intervention. A direct cost savings was estimated to be $17,500 per year and nursing<br />

time reduced by 19.4 days /year (estimate extra 10 minutes per IV administration.) There was no<br />

statistically significant difference in the length <strong>of</strong> stay, rates <strong>of</strong> readmission, death, transfer to a higher<br />

level <strong>of</strong> care, and reconversion to IV antibiotic therapy. Physician acceptance was excellent, and the<br />

process has been extended to the COPD order set.<br />

Conclusion: A simple change in process substantially reduces time from IV to PO azithromycin<br />

conversion in hospitalized patients with CAP, without compromising medical care. The process reduces<br />

cost and saves nursing time. In order to impact length <strong>of</strong> stay, the team will develop the current<br />

program to standardize discharge criteria and define appropriate oral antibiotic choice in this era <strong>of</strong><br />

increased pneumococcal resistance to azithromycin.<br />

Why do Patients Bounce Back? Findings <strong>of</strong> Reasons for Readmission among Patients Age 65 and Older<br />

in a Community Hospital<br />

Joy L. Montes MD, Kaihong Mi MD, Shazia Nazir MD, David Livert PhD, Mahesh Krishnamurthy MD FACP<br />

Introduction: Hospital readmissions have increased substantially over the past 30 years. Such an event<br />

is not only an emotional burden to patients and their families, but is very costly as well. Because <strong>of</strong> these<br />

implications, the recently passed health-care reform legislation aims at reducing readmissions and plans<br />

to penalize both hospitals and physicians who have higher than average readmission rates.<br />

Multiple factors that contribute to hospital readmissions have been cited in the literature. Identification<br />

<strong>of</strong> these risk factors locally will allow us to target interventions that will prevent readmissions at our<br />

hospital.<br />

OBJECTIVES: To identify reasons for readmission <strong>of</strong> older patients in our hospital and to examine<br />

whether there are clear factors associated with early versus late hospital readmissions. We<br />

hypothesized that patients non- compliance is the major reason for all cause readmissions.<br />

Methods: Data were analyzed on a random sample <strong>of</strong> patients aged 65 and older who were admitted to<br />

our hospital between December 1, 2008 and December 30, 2009. The most likely reason for readmission<br />

was identified. The list <strong>of</strong> reasons for readmissions was drawn upon those cited in similar readmission<br />

studies.<br />

Results: 198 patients were included in the study accounting for a total <strong>of</strong> 324 readmissions. Of these, 25<br />

% were readmitted within 7 days and 75% were readmitted between 8 and 30 days post discharge.<br />

Nearly three out <strong>of</strong> ten (30%) readmission episodes could be attributed to a health-care associated<br />

infection. Two other frequent reasons for readmission were that the patient required skilled nursing<br />

upon discharge but did not receive it (21%) and, that the patient was diagnosed with other chronic<br />

diseases (19%). Contrary to our expectations, patient noncompliance accounted for roughly 1 out <strong>of</strong> 7<br />

(14%) readmission episodes.<br />

Patients who were readmitted because they required skilled nursing upon discharge (and did not receive<br />

it) were significantly more likely to be readmitted later (24%) than earlier (13%). Patients who exhibited<br />

poor health on discharge were significantly more likely to be admitted earlier (10%) than later (3%).<br />

Conclusion: High readmission rates are an overall marker <strong>of</strong> a poor health care delivery system.<br />

Therefore, we need to constantly monitor the reasons for readmissions in our patients. Based on our<br />

findings, avoidance <strong>of</strong> readmission may be secured through interventions designed to prevent and<br />

contain health-care associated infections and enhanced discharge planning. The involvement <strong>of</strong> all<br />

stakeholders is required in order to reduce this problem, improve patient and physician satisfaction,<br />

avoid penalties and possibly better reimbursement for both hospitals and physicians.<br />

Concordance Between MRCP and ERCP for Biliary Stone Detection<br />

Dr. Chathur Acharya, Yazan Roumani, Dr. Sudhir Narla, Dr. Ibrahim Ghobrial<br />

Introduction: In the past 2-3 decades, Endoscopic Retrograde Cholangiopancreatography (ERCP) has<br />

been the gold standard for diagnosing biliary ductal dilation and stones. ERCP, however, has its<br />

drawbacks; it is technically challenging, is operator dependant and carries the risk <strong>of</strong><br />

pancreatitis. Magnetic Resonance Cholangiopancreatography (MRCP) provides an alternative noninvasive<br />

imaging tool. An evolving concept is to limit ERCP to intervention only. However, it is our<br />

observation that the results <strong>of</strong> MRCP and ERCP are frequently in disagreement. We set out to study the<br />

level <strong>of</strong> agreement between these imaging modalities.<br />

Methods: Using the <strong>of</strong> University <strong>of</strong> Pittsburgh (UPMC) system database, data <strong>of</strong> patients who<br />

underwent MRCP’s followed by ERCP’s within a 30-day time period was collected. Data included the<br />

presence and location <strong>of</strong> biliary stones, and the presence <strong>of</strong> biliary duct dilatation or stricture. The<br />

duration between the imaging studies was documented. Level <strong>of</strong> agreement between the two tests was<br />

examined using kappa statistics.<br />

Results: A total <strong>of</strong> 110 MRCP and their subsequent ERCP reports were studied. 86 <strong>of</strong> the studies were<br />

done within a week. We found a very little level <strong>of</strong> agreement between MRCP and subsequent ERCP’s.<br />

For stone detection the Kappa statistic was 0.455 (p

Tackling the Readmission Epidemic, A Resident Teaching Service Perspective<br />

Ravi K Sharma Additional authors: Dhakarwal P, Violago J, Bhasin R, Akinfolarin A, Ghobrial I<br />

Introduction: Hospital re-admissions are common and add a great burden to the cost and resources <strong>of</strong><br />

health care. Readmission rates will soon serve as a quality measure negatively impacting hospital and<br />

physician reimbursement. Most <strong>of</strong> the current studies are on general admissions and do not provide<br />

specific data applicable to populations served by resident teaching services.<br />

It is important to analyze causes <strong>of</strong> hospital readmission, formulate an assessment tool to identify high<br />

risk patients and areas <strong>of</strong> “optimum return” to channel our resources. This study will help develop<br />

systematic approach to rectify the causes, recognize potential intervention and reassess the impact after<br />

implementation.<br />

Methods: Retrospective analysis <strong>of</strong> health records (H/P, Discharge summary, ER, nursing, progress notes<br />

and <strong>of</strong>fice notes) at resident teaching services from August 2010 to May 2011. 204 readmissions within<br />

30 days <strong>of</strong> discharge irrespective <strong>of</strong> discharge or readmission diagnoses were analyzed.<br />

Results: Causes <strong>of</strong> readmissions were diverse: 28% patient factors (non-compliance, drug/alcohol use),<br />

29% end stage illness (e.g. COPD, CHF, Cancer), 4% medication problem (cost, coverage, prescription<br />

error), 3% premature discharge or early return from nursing home (3%), 3% inadequate instructions and<br />

poor follow up (6%) or inappropriate discharge level <strong>of</strong> care (3%). Readmissions due to new diagnoses<br />

were also accounted (21%).<br />

Conclusion: Multiple factors contribute to readmissions hence it is not realistic to expect one single<br />

solution. With 28% <strong>of</strong> readmissions due to lifestyle choices, insurer should develop patients’ incentives<br />

to enhance compliance. With 21% <strong>of</strong> readmissions due to new diagnoses, punitive measures against<br />

hospitals and physicians are unwarranted. Improving system based practices like collaborating drug<br />

addiction programs with hospitals, enhancing interdisciplinary approach for comprehensive medical<br />

reconciliation, reviewing medication formulary status and discharge instruction, assessing level <strong>of</strong><br />

discharge, ensuring appropriate follow up, early implementation <strong>of</strong> medical care guidelines and end <strong>of</strong><br />

life care are important to curb readmission rates.<br />

Comparison Between Transthoracic and Transesophageal Echo in the Detection <strong>of</strong> Vegetations in<br />

Endocarditis Patients: A Retrospective Analysis<br />

Abhishek Biswas, MBBS Additional authors: Misra S,Yassin M,Pinevich A<br />

Introduction: Echocardiograms have served as a backbone <strong>of</strong> the diagnostic methodology for infective<br />

endocarditis. Transthoracic echocardiogram (TTE) has been found to have a lower sensitivity for<br />

detection <strong>of</strong> vegetations as compared to transesophageal echocardiogram (TEE) (85-95%). TEE is<br />

routinely ordered in cases <strong>of</strong> suspected endocarditis. The AHA guidelines recommend TEE as the initial<br />

test to rule out endocarditis in high risk individuals.Objectives <strong>of</strong> the study: This retrospective review<br />

was a quality improvement study aimed at showing if there is any additional benefit from ordering TTE<br />

prior to ordering TEE in high- risk patients with suspected endocarditis. The study also looked into the<br />

cost analysis <strong>of</strong> ordering TTE prior to TEE.<br />

Methods: A retrospective chart review treated at UPMC Mercy between May 2009 and June 2011 was<br />

performed. Using standardized billing codes, patients were selected based on the following criteria: 1)<br />

had a final diagnosis <strong>of</strong> endocarditis, 2) underwent both TTE and TEE and 3) had presence <strong>of</strong> a<br />

vegetation on TEE.<br />

Results: The review found 27 patients with endocarditis fulfilling the inclusion criteria. The results <strong>of</strong> this<br />

study showed that TTE detected evidence <strong>of</strong> vegetations in only 29.6% <strong>of</strong> the patients included. Review<br />

<strong>of</strong> literature showed that TEE has sensitivity around 90%. Sensitivity was especially low for detection <strong>of</strong><br />

vegetation on mitral (11%) and tricuspid (16.7%) valves. From a financial standpoint, the cost <strong>of</strong> TTE<br />

could have been saved if TEE had been done as the initial diagnostic study.<br />

Conclusion: In high-risk patients with suspected endocarditis, TEE should be ordered initially. TTE does<br />

not add any beneficial information and is not cost-effective.<br />

Evidence for the Prevention <strong>of</strong> Ventilator Associated Pneumonia: Systematic Review and Metaanalysis<br />

<strong>of</strong> Randomized Controlled Trials<br />

Leena Jalota, MD<br />

Introduction: Ventilator associated pneumonia (VAP) is associated with an increase in mortality in<br />

critically ill patients and poses a significant economic burden on our health care system. Numerous<br />

preventive strategies have been extensively investigated, yet, there is currently no comprehensive<br />

review that systematically evaluated <strong>of</strong> all available evidence.Hence our objective is to provide clinicians<br />

with a comprehensive, evidence-based overview that includes all published interventions for the<br />

prevention <strong>of</strong> VAP.<br />

Methods:<br />

Data Sources: Published articles through June 2011 from Pubmed, EMBASE, CINAHL, ISI andthe<br />

133<br />

Cochrane Database, complemented with a hand-search <strong>of</strong> references. Ongoing trials were<br />

identified using www.clinicaltrials.gov and authors contacted for relevant data.<br />

Study Selection: Randomized controlled trials <strong>of</strong> critically ill adult patients requiring mechanical<br />

ventilation and in whom pneumonia was a measured outcome.<br />

Data Extraction: A total <strong>of</strong> 2073 publications were screened and 185 met predefined inclusion<br />

criteria. Odds ratios with 95% confidence intervals (OR; 95% CI) were determined using RevMan<br />

5.1.<br />

Results:The following interventions – based on multiple studies and sorted according to their effect size<br />

– significantly reduced the incidence <strong>of</strong> VAP: Weaning protocols for non-invasive ventilation (0.14; 0.07-<br />

0.25), subglottic suctioning (0.34; 0.24-0.49), Rotational therapy (0.34; 0.23-0.52), selective<br />

decontamination <strong>of</strong> the gut (0.37; 0.32-0.43), oral care with chlorhexidine (0.51; 0.35-0.75), aerosolized<br />

antibiotics (0.52; 0.28-0.95), systemic antibiotics (0.56; 0.32-0.99) oral probiotic administration (0.59;<br />

0.36-0.98, silver coated tubes (0.62; 0.43-0.88) and sucralfate as an alternative to H2-antagonists (0.77;<br />

0.61-0.97). The following interventions – based on single studies only – were also statistically<br />

significant: Antioxidant therapy (0.12; 0.03-0.49), chest physiotherapy (0.14; 0.03-0.70), oral care with<br />

povidone-iodine (0.14; 0.04-0.58), trace element supplementation (0.15; 0.03-0.68), subglottic<br />

decontamination (0.17; 0.05-0.56), and enteral versus parenteral nutrition (0.39; 0.18-0.85). All other<br />

interventions failed statistical significance, including several commonly advocated interventions such as<br />

semi recumbent positioning (0.4; 0.15-1.04), early tracheostomy (0.66; 0.31-1.38), and prone positioning<br />

(0.82; 0.58-1.18).<br />

Conclusion: There are various pharmacological and non-pharmacological interventions that reduce the<br />

incidence <strong>of</strong> VAP. A common characteristic seems to be that all these interventions work around the<br />

principle <strong>of</strong> reducing the micro-aspiration and the related bacterial load. Implementation <strong>of</strong> these<br />

strategies into practice will definitely help in controlling the incidence <strong>of</strong> a seriously morbid and a life<br />

threatening nosocomial infection.

Empanelment – A Way to Improve Continuity <strong>of</strong> Care, Healthcare Quality and Patient Satisfaction<br />

Keyur K Mavani, MBBS, Other authors: Nanavaty S. MD, Thomas L. MD, Sheth J. MD, Yellappa S. MD<br />

Introduction: Physician-patient relationship, trust and faith in physician, patient safety and patient<br />

satisfaction come from continuity <strong>of</strong> care. In our out-patient practice <strong>of</strong> more than 5000 patients, we<br />

noticed that many patients were seen by different physicians, residents and extenders at each<br />

visit. Patient satisfaction was worsening and complaints were increasing along with lack <strong>of</strong> continuity<br />

leading to decline in quality, safety and communication. The quality <strong>of</strong> care, safety and patient<br />

satisfactions are our goal at our practice. Our observation suggested that providing a systematic way to<br />

allow patients to see their own resident and PCP will be the best way to manage these growing<br />

concerns. As a result <strong>of</strong> long discussion to improve in these areas, we decided to do a quality<br />

improvement project named as “Empanelment”.<br />

Methods:<br />

1. We cleaned patient registry and created a list <strong>of</strong> patients who were active in last 3 years. The<br />

number came close to 5000.<br />

2. Calculated supply <strong>of</strong> physicians and extenders according to their FTEs.<br />

3. For the already established patients, we went into individual patient’s appointment history and<br />

linked them with their preferred providers.<br />

4. Assigned 350 patients to each resident. Panel sizes were adjusted for diabetes and Hypertension<br />

maintaining age range.<br />

5. Second option was provided as a backup for physicians, residents and extenders in the<br />

“preferred provider form” – a document we created in our EMR.<br />

6. Schedulers were trained to schedule according to this preferred provider form.<br />

7. Entire process was made patient centered. Patient can change their provider if they are not<br />

happy with the provider assigned to them.<br />

8. Planned to review every 3 months with reports generated by out electronic medical record<br />

system.<br />

Results: The results in first 3 months after implementation are encouraging. The clinic is more<br />

organized. Patients are more satisfied as they are seen by the same resident and physician during each<br />

visit. The numbers <strong>of</strong> complaints regarding patient scheduling have decreased by 75%. Residents are<br />

more proactive managing their own patients, taking the ownership and scheduling their appointment<br />

with them, than before. Although it is a difficult task for schedulers, they are adapting to new system<br />

steadily.<br />

Conclusion: We strongly believe that the concept <strong>of</strong> empanelment will change the way medicine is<br />

practiced, especially in residency programs, which potentially will improve resident education. In near<br />

future ‘Empanelment’ will take the level <strong>of</strong> education to higher level and prepare the doctors in training<br />

to provide better, safer and efficient care to their patients.<br />

Improving the Quality <strong>of</strong> Care for Critically Ill Patients Immediately After Intubation<br />

Faraz S. Ahmad, MD Ryan A. McConnell, MD Mitesh S. Patel, MD, MBA Barry D. Fuchs, MD Meeta<br />

Prasad, MD, MSCE<br />

Introduction: Post-intubation is a vulnerable time for critically ill patients in the medical intensive care<br />

unit. Delayed monitoring and management <strong>of</strong> ventilation status and lack <strong>of</strong> communication amongst<br />

interdisciplinary care team members can cause significant patient harm. The arterial blood gas (ABG) is<br />

used to monitor physiologic response after intubation.<br />

Outline <strong>of</strong> Problem: Morbidity and Mortality Review (M&M) at the Hospital <strong>of</strong> the University <strong>of</strong><br />

Pennsylvania identified two adverse events related to delayed monitoring <strong>of</strong> ventilation status in<br />

recently intubated patients. Lack <strong>of</strong> protocols for patient care and provider communication were<br />

identified among the root causes. Our objective was to evaluate the impact <strong>of</strong> a multidisciplinary Post-<br />

Intubation Time Out process on the quality <strong>of</strong> care <strong>of</strong> mechanically ventilated patients.<br />

Methods: Strategy for Change: A multidisciplinary Post-Intubation Time Out document was developed<br />

for the care team to administer after each intubation. Nurses (RNs), respiratory therapists (RTs), and<br />

physicians (MDs) were involved in document creation and each received education prior to<br />

implementation. The Time Out includes a checklist <strong>of</strong> key tasks and assigns responsibilities to each<br />

member to be completed within 1 hour.<br />

Process <strong>of</strong> Gathering Information: Data were retrospectively collected on patients intubated prior to the<br />

M&M and prospectively collected on patients intubated after Time Out implementation.<br />

Key Measures for Improvement: Primary process measurements include time from intubation to ABG<br />

result, proportion <strong>of</strong> patients with ABG resulted in less than 1 hour, and percentage <strong>of</strong> Time Outs with at<br />

least an RN, RT, and MD participant.<br />

Results: Analysis and Interpretation: Prior to Time Out implementation, mean time from intubation to<br />

ABG result was 151.3 minutes, (95% Confidence Interval [95% CI]: 66.5-228.2). Proportion <strong>of</strong> patients<br />

with ABG resulted in less than 1 hour was 27.3%. No guidelines exist for ventilation monitoring postintubation,<br />

though it is known that carbon dioxide reaches steady state in approximately 15<br />

minutes. Thus, a mean <strong>of</strong> 151.3 minutes represents a potentially dangerous delay in care.<br />

Effects <strong>of</strong> Change: Amongst 36 patients intubated after implementation <strong>of</strong> the Time Out, 88.9% had an<br />

RN, RT, and MD participant. Mean time from intubation to ABG result decreased to 76.3 minutes (95%<br />

CI: 54.8-87.5). Proportion <strong>of</strong> patients with ABG resulted in less than 1 hour more than doubled to<br />

63.9%.<br />

Conclusion: The Post-Intubation Time Out process improved the coordination and timeliness <strong>of</strong> postintubation<br />

patient care. The Time Out continues to be used to reach a target sample size <strong>of</strong> 60 patients<br />

in each group, at which time evaluation for statistical significance will be conducted. If successful, the<br />

Time Out will be expanded to other ICUs to demonstrate reproducibility in multiple settings.<br />

Introduction: While the intervals for repeating colonoscopy for colorectal cancer(CRC) screening or for<br />

polyp surveillance are well described, there are no set guidelines for repeating a colonoscopy for other<br />

indications such as recurrent lower gastrointestinal bleeding (LGIB) or abdominal pain. It is also not<br />

known if repeating a colonoscopy for these indications is useful. This study aims to assess the yield <strong>of</strong><br />

repeat colonoscopy performed for the same indication other than CRC screening or polyp surveillance<br />

within three years <strong>of</strong> the index procedure in producing changes in clinical management.<br />

Methods: A retrospective review <strong>of</strong> patients who had more than one colonoscopy performed for the<br />

same indication within three years at Albert Einstein Medical Center between January 1,2000 and<br />

January 1,2010 was conducted. Exclusions included patients with repeat colonoscopies performed for<br />

CRC screening/surveillance or poor bowel preparation. Clinical parameters including age, sex, race,<br />

interval between procedures, indication <strong>of</strong> the procedure, presenting symptoms, severity <strong>of</strong> symptoms,<br />

hemodynamic instability, duration between onset <strong>of</strong> symptoms and the procedure, change in<br />

endoscopist, withdrawal time, location <strong>of</strong> colonic lesions and quality <strong>of</strong> bowel preparation were<br />

analyzed with bivariate analysis and logistic regression analysis to examine correlation with clinically<br />

significant change, defined as any change in management during or after the procedure.<br />

Results: Among 19,772 colonoscopies performed during above mentioned period, 139 pairs <strong>of</strong><br />

colonoscopies met the inclusion criteria. The vast majority <strong>of</strong> repeat colonoscopies were for<br />

LGIB(88.4%), changes in bowel habit(6.4%) and abdominal pain(5%). Among 139 eligible pairs <strong>of</strong><br />

colonoscopies, only repeat colonoscopies that were done for LGIB and abdominal pain produced<br />

endoscopic findings that resulted in a change in management (27 out <strong>of</strong> 123 and 2 out <strong>of</strong> 7,<br />

respectively). When looking at only recurrent LGIB cases, endoscopic findings included 8 new<br />

hemorrhoid lesion(6.5%), 7 actively bleeding lesions requiring endoscopic interventions(5.7%), 7<br />

previously undetected polyps(6 were smaller than 1 cm(4.9%) and 1 was larger than 1 cm(0.8%)), 3<br />

radiation proctitis/colitis(2.43%), 1 rectal ulcer(0.8%), and 1 previously undetected cancer(0.8%). Of all<br />

parameters analyzed, only the interval between procedures more than one year (1-2 and 2-3 years) was<br />

MD, MPH, ScD<br />

Introduction: Nearly 2 million premature deaths worldwide are attributed to air pollution which poses a<br />

major environmental risk to health. A number <strong>of</strong> cohort studies from the United States and Europe have<br />

shown that long-term exposure to fine particulate matter (PM 2.5) is an important predictor <strong>of</strong> mortality<br />

for cardiopulmonary disease. However, few studies have examined the effects <strong>of</strong> PM 2.5 in the Asian<br />

population. We examined the association <strong>of</strong> long-term exposure to PM2.5 with cardiovascular and<br />

cerebrovascular (CVD) mortality in Taiwan.<br />

Methods: In this prospective cohort study, we followed 13,276 subjects in 4 townships across Taiwan<br />

from 1991-2009. Information on sociodemographic and behavioral factors and blood chemistry was<br />

collected at baseline. Mean pollution levels for PM2.5 at the township level during 2000-2009 were<br />

estimated by a combination <strong>of</strong> statistical and geospatial methods using recorded level <strong>of</strong> PM 2.5 (since<br />

2005) and PM 10 (since 2000) from 67 monitoring stations in Taiwan. The underlying cause <strong>of</strong> death was<br />

determined by ICD-9 and ICD-10 codes. We estimated the effects <strong>of</strong> air pollution CVD mortality using<br />

Cox proportional-hazards regression modeling, while controlling for individual risk factors. Since the<br />

baseline hazard <strong>of</strong> CVD mortality might vary in different regions (north/south), we further conducted a<br />

stratified Cox regression analysis by region.<br />

Results: During the 19-year follow-up, there were 286 deaths due to cardiovascular and/or<br />

cerebrovascular causes (189 males and 97 females). In the unadjusted analysis, CVD mortality by<br />

township was not significantly associated with air pollution (HR=1.07 for every 10ug/m3 increase in<br />

PM2.5; 95% CI=0.96-1.20). The association remained non-significant (HR=1.02 for every 10ug/m3<br />

increase in PM2.5; 95% CI=0.91-1.15) even after adjusting for individual-level risk factors (gender, age,<br />

education, smoking, pack-years, alcohol, body mass index, triglyceride and cholesterol levels, diabetes,<br />

hypertension, and glomerular filtration rate). In the stratified analysis by region, there was a stronger<br />

association between PM 2.5 and CVD mortality in the multivariate-adjusted model (HR=1.21 for every<br />

10ug/m3 increase in PM2.5; 95% CI=0.95-1.54). The effect <strong>of</strong> PM 2.5 was possibly modified by sex (p for<br />

interaction: 0.066), with males being more susceptible than females. We did not find evidence <strong>of</strong> effect<br />

modification by chronic disease status (p for interaction: 0.41).<br />

Conclusion: This population-based cohort study from Taiwan provides some supporting evidence <strong>of</strong> a<br />

positive association between CVD mortality with fine particulate air pollution when stratified by north<br />

and south regions. However, most <strong>of</strong> the observed associations were not statistically significant; possibly<br />

due to the small number <strong>of</strong> events and measurement error in PM 2.5 levels. The possibility that males<br />

might be more vulnerable to the effects <strong>of</strong> PM 2.5 needs to be further investigated.<br />

Riyadh, 11525, Saudi Arabia.<br />

Introduction: Antibiotics sales without medical prescriptions are increasingly recognized as sources <strong>of</strong><br />

antimicrobial misuse that can exacerbate the global burden <strong>of</strong> antibiotic resistance. We aimed to<br />

determine the percentage <strong>of</strong> pharmacies who sell antibiotics without medical prescriptions, examining<br />

the potential associated risks <strong>of</strong> such practice in Riyadh, Saudi Arabia, by simulation <strong>of</strong> different clinical<br />

scenarios.<br />

Methods: A cross sectional study <strong>of</strong> a quasi-random sample <strong>of</strong> pharmacies stratified by the five regions<br />

<strong>of</strong> Riyadh. Each pharmacy was visited once by two investigators who simulated having a relative with a<br />

specific clinical illness (sore throat, acute bronchitis, otitis media, acute sinusitis, diarrhea, and urinary<br />

tract infection (UTI) in childbearing aged women).<br />

RESULTS: A total <strong>of</strong> 327 pharmacies were visited. Antibiotics were dispensed without a medical<br />

prescription in 244 (77.6%) <strong>of</strong> 327, <strong>of</strong> which 231 (95%) were dispensed without a patient request.<br />

Simulated cases <strong>of</strong> sore throat and diarrhea resulted in an antibiotic being dispensed in (90%) <strong>of</strong><br />

encounters, followed by UTI (75%), acute bronchitis (73%), otitis media (51%) and acute sinusitis (40%).<br />

Metronidazole (89%) and cipr<strong>of</strong>loxacin (86%) were commonly given for diarrhea and UTI, respectively,<br />

whereas amoxicillin/clavulanate was dispensed (51%) for the other simulated cases. None <strong>of</strong> the<br />

pharmacists asked about antibiotic allergy history or provided information about drug interactions. Only<br />

23% asked about pregnancy status when dispensing antibiotics for UTI-simulated cases.<br />

CONCLUSION: We observed that an antibiotic could be obtained in Riyadh without a medical<br />

prescription or an evidence-based indication with associated potential clinical risks. Strict enforcement<br />

and adherence to existing regulations are warranted<br />

Background: Emerging epidemiological evidence suggests that statin use may reduce the risk <strong>of</strong><br />

community-acquired pneumonia (CAP) and its complications.<br />

Purpose: To systematically review the association between statin use and the risk <strong>of</strong> CAP and related<br />

mortality.<br />

Data source: Ovid MEDLINE, EMBASE, ISI Web <strong>of</strong> Science, and Scopus from inception through December<br />

2011 were searched for randomized trials, cohort and case-control studies.<br />

Study selection: Two authors independently reviewed analytical studies that examined the role <strong>of</strong><br />

statins in CAP<br />

Data extraction: Data about study characteristics, adjusted effect-estimates and quality characteristics<br />

was extracted.<br />

Data synthesis: Eighteen studies corresponding to 21 effect-estimates (eight and 13 <strong>of</strong> which addressed<br />

the preventive and therapeutic roles <strong>of</strong> statins, respectively) were included. All studies were <strong>of</strong> good<br />

methodological quality. Random-effects meta-analyses <strong>of</strong> adjusted effect-estimates were used. Statins<br />

were associated with a lower risk <strong>of</strong> CAP, 0.84 (95% CI, 0.74-0.95), I2 = 90.5% and a lower short-term<br />

mortality in patients with CAP, 0.68 (95% CI, 0.59-0.78), I2 = 75.7%. Meta-regression did not identify<br />

sources <strong>of</strong> heterogeneity. A funnel plot suggested publication bias in the treatment group. A novel<br />

regression method to adjust for publication bias resulted in an adjusted -estimate <strong>of</strong> 0.85 (95% CI, 0.77-<br />

0.93). Sensitivity analyses using the rule-out approach showed that it is unlikely that the results were<br />

due to an unmeasured confounder.<br />

Limitations: Observational studies and between-study inconsistency<br />

Conclusions: The results <strong>of</strong> a rigorously conducted systematic review and meta-analysis suggest that<br />

statins have a beneficial effect in reducing risk and improving mortality <strong>of</strong> CAP<br />

Introduction: To investigate the clinical and pathological features, outcome and its predictors in<br />

glomerulonephritis with crescents among adult patients<br />

Method: This is a retrospective study <strong>of</strong> crescentic GN over a 9 years period. Histological features, renal<br />

function at presentation and renal outcome among different etiological groups were compared at<br />

baseline and end <strong>of</strong> follow up period.<br />

Results: The mean age was 27.7 ± 9.9 years in the lupus nephritis (LN) group, and 46.9± 18 in the pauciimune<br />

glomerulonephritis (PIGN) group (p=0.001). 49.3% were due to LN and 26.5% due to PIGN. 85.7%<br />

had renal impairment at presentation (73.3% in LN and 100% in PIGN). Females accounted for 85.3 %,<br />

76.5% and 36.2% in LN, PICN and ICGN respectively (p=0.025).<br />

By the end <strong>of</strong> the follow up period <strong>of</strong> 26± 22.9 months, 25.8% <strong>of</strong> the patients needed dialysis (16.70% in<br />

LN, 50% in PIGN and 25% in ICGN (p=0.05) while 21.7 % had nephrotic range proteinuria (16.7 %, 1%<br />

and 33.3 % respectively (p=0.4).<br />

Comparing LN, PIGN and ICGN using ANOVA, we found significant differences between groups in gender<br />

(p =0.035), in % <strong>of</strong> sclerorsed glomeruli (SG) (p=0.012) and age (p=0.006).<br />

Using multivariate analysis, we found the independent predictors for hemodialysis requirement and<br />

renal prognosis to be SG, ATN, degree <strong>of</strong> Bowman membrane thickening and vasculopathy but not the<br />

baseline proteinuria or SCR, gender or the number <strong>of</strong> glomeruli with crescents.<br />

Conclusion: Almost half <strong>of</strong> our patients with CrGN were due to LN. Patients with PICN were older and<br />

had worse prognosis. Predictors <strong>of</strong> renal death were SG and ATN. This could be explained by the higher<br />

number <strong>of</strong> globally sclerorsed glomeruli in the PIGN group.<br />

An Analysis <strong>of</strong> House Officer Implementation <strong>of</strong> Standardized Hand-Off.<br />

Elmira Basaly, MD Elizabeth Edwards, MD Rashmi Ganith, MD Alexis Lewis, MD Myron Kung, MD<br />

Caroline Powell, MD<br />

Introduction: The Institute <strong>of</strong> Medicine estimated that up to 98,000 deaths occur each year because <strong>of</strong><br />

preventable medical errors. Significant portion <strong>of</strong> medical errors arise from miscommunication during<br />

transfer <strong>of</strong> care. In most residency programs, trainees manage transitions via verbal, written, or<br />

combined methods <strong>of</strong> communication termed “hand-<strong>of</strong>fs.” In 2003, the Accreditation Council for<br />

Graduate Medical Education (ACGME) instituted a mandatory 80-hour work week to reduce medical<br />

errors related to decisions made by exhausted residents. A consequence <strong>of</strong> work hour restrictions is that<br />

patient care has become more fragmented with multiple requisite hand-<strong>of</strong>fs. Despite the critical<br />

importance <strong>of</strong> hand-<strong>of</strong>fs, little research has examined the content, procedure, and effectiveness <strong>of</strong> this<br />

process. Even less is known about how hand-<strong>of</strong>fs should be conducted or how interventions might<br />

improve the quality <strong>of</strong> hand-<strong>of</strong>fs.<br />

Methods: Our hypothesis was that implementation <strong>of</strong> a standardized hand-<strong>of</strong>f would lead to improved<br />

resident perception and quality <strong>of</strong> hand-<strong>of</strong>f. We conducted a prospective cohort study <strong>of</strong> hand-<strong>of</strong>f<br />

perception pre and post implementation <strong>of</strong> a standardized process amongst 30 internal medicine<br />

residents at Palmetto Health Richland between January to July 2011. A survey before and after the<br />

implementation <strong>of</strong> a standardized hand <strong>of</strong>f was distributed. Post-implementation data was compared to<br />

pre-implementation data using a paired two-tailed t-test (p= 0.05) analysis <strong>of</strong> a composite score to<br />

assess strength <strong>of</strong> effect. The survey contained 5 questions. Responses were ranked from 1 to 5. The<br />

composite score included each question weighted equally with secondary outcomes (number <strong>of</strong> calls,<br />

number <strong>of</strong> transfers or medical events) factored into the analysis.<br />

Results: A standardized hand-<strong>of</strong>f has been implemented within our residency program. We recommend<br />

standardized hand-<strong>of</strong>f to include updated information, anticipated events and guidance, with priority<br />

given to sickest patients. Two questions, regarding unanticipated events and formal instruction had a<br />

near acceptable p-value with our study.<br />

Conclusion: Standardized hand-<strong>of</strong>f is meant to improve quality <strong>of</strong> care ultimately leading to patient<br />

safety and resident confidence in decision making. Our next phase is to study satisfaction and<br />

Factors that Influence Confidence in Patient Counseling on Physical Activity in Attending <strong>Physicians</strong>,<br />

Resident and Fellow <strong>Physicians</strong>, and Medical Students in the United States<br />

Fatima Cody Stanford, MD, MPH; Martin W. Durkin, MD; Caroline Keller Powell, MD, MSCR; Mary Beth<br />

Poston, MD, MSCR; James Rast Stallworth, MD, and Steven N. Blair, PED<br />

Introduction: In 2008, the US Department <strong>of</strong> Health and Human Services (USDHHS) released its first<br />

national guidelines for physical activity. More than 80% <strong>of</strong> adults do not meet the guidelines for both<br />

aerobic and muscle-strengthening activities. Very few studies have been performed to determine the<br />

level <strong>of</strong> physical activity in physicians and medical students. There is evidence that the level <strong>of</strong> physical<br />

activity <strong>of</strong> physicians may be correlated directly with physician counseling pattern about this<br />

behavior. The objective <strong>of</strong> our study was to determine which factors are associated with a higher<br />

likelihood <strong>of</strong> confidence in counseling patients about physical activity.<br />

Methods: We established an online exercise survey targeted at attending physicians, resident and fellow<br />

physicians, and medical students to determine their current level <strong>of</strong> physical activity and confidence in<br />

counseling patients about physical activity. Their level <strong>of</strong> physical activity was compared with the 2008<br />

physical activity guidelines <strong>of</strong> the USDHHS. The survey was generated using the short form <strong>of</strong> the<br />

International Physical Activity Questionnaire (IPAQ). The period <strong>of</strong> data collection was approximately 8<br />

months (June 2009- January 2010). The results were analyzed with logistic regression and stratification<br />

<strong>of</strong> two by two tables using the Mantel-Haenszel chi-squared test.<br />

Results: A total <strong>of</strong> 1949 individuals responded to the survey; 1751 were included in this analysis (566<br />

attending physicians, 138 fellow physicians, 806 resident physicians, and 215 medical students). The<br />

odds <strong>of</strong> an individual who met the USDHHS guidelines for vigorous activity being confident in exercise<br />

counseling were 2.23 times those <strong>of</strong> an individual who did not meet the USDHHS vigorous activity<br />

guidelines after adjusting for BMI (p

Muhammad U Khan, MBBS Other Authors: Atta Ur-Rehman Shahbaz, MBBS; Heena Khalid, MBBS; Karl T.<br />

Weber MD.<br />

Introduction: Acute stressor states involves neurohormonal activation with elevations in plasma<br />

catecholamines that promote translocation <strong>of</strong> circulating cations into s<strong>of</strong>t tissues. In the heart, the<br />

resultant dyshomeostasis <strong>of</strong> extra- and intracellular cations is accompanied by the prolongation <strong>of</strong><br />

myocardial repolarization with a greater propensity for atrial and ventricular arrhythmias and<br />

nonischemic cardiomyocyte necrosis. Herein, we studied serum electrolytes and troponin-I (trop-I),<br />

corrected QT interval (QTc) from the ECG, and the appearance <strong>of</strong> arrhythmias in acutely ill patients<br />

hospitalized in a medical intensive care unit (MICU) to elucidate their potential pathophysiologic<br />

correlations.<br />

Methods: A retrospective chart review <strong>of</strong> 200 consecutive patients (58±1 yrs; 106 females) admitted to<br />

a MICU from April to August 2010, with acute stressors, such as sepsis, pulmonary embolus, acute<br />

lymphocytic leukemia, intracranial hemorrhage, subdural hematoma, or diabetic ketoacidosis, and who<br />

did not have previously documented arrhythmia or chronic renal failure (serum creatinine >1.4<br />

Idiopathic Intracranial Hypertension Associated with Hypocalcemia and Aldosteronism: A Case Series<br />

Muhammad U Khan, MBBS Heena Khalid, MBBS; Karl T. Weber, MD.<br />

Introduction: Idiopathic intracranial hypertension (IIH), also known as pseudotumor cerebri, is a clinical<br />

syndrome whose symptoms and signs include headache, with or without visual disturbances and field<br />

defects, together with papilledema. The pathogenic origins <strong>of</strong> IIH remain uncertain. In our previous<br />

report (J Investig Med 2011;59:402), we summarized 10 patients with IIH having primary or secondary<br />

aldosteronism. Aldosteronism is a known cause <strong>of</strong> hypocalcemia which has been reported in some<br />

cases <strong>of</strong> IIH. To explore the pathomechanistic basis <strong>of</strong> this association we studied 15 reported cases<br />

with IIH and hypocalcemia <strong>of</strong> various etiologies.<br />

Methods: We conducted a retrospective study to summarize 15 patients with IIH and hypocalcemia<br />

which had been reported in the literature.<br />

Results: The female:male ratio was 9:6. Patients were 12±3 yrs old at the time when the diagnosis <strong>of</strong><br />

hypocalcemia was made, whereas they were 16±3 yrs old when IIH was diagnosed. Hypocalcemia was<br />

related to vitamin D deficiency in 11, hypoparathyroidism in 2, pseudohypoparathyroidism in 1 and an<br />

inherited renotubular defect in 1. All patients exhibited clinical symptoms related to hypocalcemia<br />

before development <strong>of</strong> symptoms <strong>of</strong> IIH. Plasma calcium levels 1.38±0.16 mM were significantly<br />

decreased (normal, 2.1–2.6 mM) as were plasma magnesium levels (0.41±0.13 mM; normal, 0.6–1.1<br />

mM). Symptoms <strong>of</strong> IIH were controlled by: polynutrient dietary supplementation in 10, lone vitamin D<br />

and calcium supplementation in 4, and cessation <strong>of</strong> thiazide diuretic and replacement <strong>of</strong> magnesium and<br />

calcium in 1.<br />

Conclusion: An association between IIH with severe symptomatic hypocalcemia has been reported in<br />

young patients while an association between IIH with primary aldosteronism occurs in hypertensive<br />

middle-age women, whereas normotensive girls having an inherited renotubular defect can have IIH<br />

with secondary aldosteronism. Patients with IIH therefore should be evaluated for both hypocalcemia<br />

and aldosteronism. Replacement <strong>of</strong> calcium and magnesium, together with the use <strong>of</strong> calcium and<br />

magnesium-conserving diuretics, <strong>of</strong>fers effective treatment for both hypocalcemia and IIH.<br />

Point <strong>of</strong> Care Testing: Efficient, but Accurate?<br />

Rahman, Owaisur MD (Associate), Rasnake, Mark MD (FACP)<br />

Introduction: Point <strong>of</strong> care testing (POCT) is utilized more frequently in emergency departments (EDs)<br />

across the United States and has had a pr<strong>of</strong>ound impact on the practice <strong>of</strong> emergency medicine. POCT is<br />

defined as medical testing at or near the site <strong>of</strong> patient care, bringing the test conveniently to the<br />

patient. Our institution recently instituted POCT in its ED. Following implementation, a difference<br />

between the POCT labs and standard labs was noted by internal medicine residents. This observation<br />

resulted in a resident-led quality improvement project which looked at the implementation <strong>of</strong> these<br />

POCT labs and how well they correlated with standard lab testing.<br />

Methods: The patient population consisted <strong>of</strong> adult patients with POCT International Normalized Ratio<br />

(i-INR) drawn and admitted to our facility through the ED over a two month period. Of these patients,<br />

only those who also had an INR value drawn by standard lab methods within three hours <strong>of</strong> the initial i-<br />

INR were included. Any patients who had interventions performed that would alter their INR value were<br />

excluded. The data was then analyzed for correlation between i-INR and standard INR values.<br />

Results: Fifteen patients who had an i-INR and a subsequent standard INR value drawn within three<br />

hours <strong>of</strong> the initial test were included in this Quality Improvement study. The average difference<br />

between the two values was .88 with a range <strong>of</strong> approximately 0 to 2.86. Further analysis <strong>of</strong> the two<br />

data sets did not show a statistically significant correlation between the values. The coefficient <strong>of</strong><br />

correlation, r, was found to be .425 and the coefficient <strong>of</strong> determination, r 2 , was determined to be .181.<br />

Given the poor correlation between the i-INR values and standard INR values, a department wide review<br />

<strong>of</strong> the POCT process was initiated. This review revealed several problems with the implementation <strong>of</strong><br />

the POCT INR to include inconsistent use <strong>of</strong> fingerstick-only blood as required by manufacturer<br />

specifications. Additionally, testing was not always performed immediately at the bedside, delaying<br />

processing <strong>of</strong> some specimens for hours. Retraining staff on the importance <strong>of</strong> strict adherence to<br />

manufacturer protocol for POCT was initiated. Follow up parallel testing <strong>of</strong> 21 sequential specimens<br />

obtained in the ED showed significant improvements in accuracy with an r <strong>of</strong> .998 and an r 2 <strong>of</strong> .997.<br />

Conclusion: Our findings demonstrate the importance <strong>of</strong> strict adherence to manufacturer protocols for<br />

POCT technology. Implementation <strong>of</strong> any new technology has the potential to produce errors as staff<br />

adapt to new procedures. Furthermore, our findings demonstrate the critical role medicine residents<br />

play in identifying and preventing system errors in healthcare.<br />

Alejandro R Trevino, MD; Jiaqiong Xu, PhD; Faisal Nabi, MD; John J. Mahmarian, MD.<br />

Introduction: Non-contrast Cardiac Computed Tomography (NCCT) allows for calculation <strong>of</strong> coronary<br />

artery calcium score (CACS) and measurement <strong>of</strong> epicardial adipose tissue and intra-thoracic fat<br />

volumes (EATv and ITFv). The aim <strong>of</strong> this study was to evaluate the value <strong>of</strong> these measurements in<br />

predicting coronary events (CEs) in compare to clinically derived cardiac risk stratification tools such as<br />

Framingham Risk Score (FRS).<br />

Methods: 760 consecutive symptomatic patients without known coronary disease underwent NCCT and<br />

were followed up to 5 years (median 3.3 years) for CEs (cardiac death, non fatal MI, and acute coronary<br />

syndrome with >70% coronary artery stenosis). The mean age was 54.4 ±13.7 years, 60 % were female,<br />

15% were diabetics, mean body mass index (BMI) <strong>of</strong> 30.6 kg/m 2 and mean FRS <strong>of</strong> 8.2. The ITFv and EATv<br />

were calculated with semi-automated method. Fat tissues were automatically recognized on CT scans by<br />

threshold between -40 and-200 Hounsfield units.<br />

Results: Compared to 715 event-free patients, the 45 patients who had CEs were older (64.8 vs 53.7 y/o<br />

p400. The area under the curve from ROC analyses showed trends to improve CE<br />

prediction when fat volume was added to FRS, BMI and log (CACS+1) (0.839 for EATv>125ml, 0.843 for<br />

ITFv>250ml vs. 0.828, p=0.14 and 0.11 respectively). On the other hand, CACS significantly improved the<br />

prediction when added to FRS and BMI (0.828 vs 0.724 p=0.001).<br />

Conclusion: Symptomatic patients with CEs had larger ITFv and EATv and higher CACS. Although both<br />

EATv and ITFv provided some incremental value over clinical information, CACS remained the strongest<br />

predictor <strong>of</strong> outcome.<br />

Introduction: Purpose: The purpose <strong>of</strong> this pilot study was to examine the effects <strong>of</strong> fluvastatin on proinflammatory<br />

and pro-thrombotic biomarkers in persistently aPL-positive patients<br />

Methods: Persistently aPL-positive patients received fluvastatin 40 mg daily for 3 months (m). At 3m,<br />

patients were instructed to stop fluvastatin and they were followed for another 3m. Persistent aPL<br />

positivity was defined as IgG/M aCL = 40U, IgG/M aß2GPI = 20U, and/or positive LA test on =2 occasions<br />

at least 12w apart. Selected exclusion criteria were pregnancy, statin use, prednisone >10 mg/day, and<br />

immunosuppressive use (except hydroxychloroquine) at the time <strong>of</strong> the screening. Serum samples were<br />

collected at baseline and monthly thereafter for 6m. IFNa2, IL1ß, IL6, IL8, IP10, MCP1, TNFa, VEGF, and<br />

sCD40L levels were determined by the MILLIPLEXMAP human cytokine/chemokine assay (Millipore,<br />

Billerica, MA). Plasma samples were used to detect soluble tissue factor (sTF) using a chromogenic assay.<br />

CRP was evaluated by a nephelometric assay. aCL, aß2GPI, soluble ICAM-1, VCAM-1, and E-selectin were<br />

evaluated by ELISA. For the purpose <strong>of</strong> this preliminary analysis <strong>of</strong> baseline, 1m, 2m, and 3m samples,<br />

we: a) compared baseline biomarker levels <strong>of</strong> patients with serum samples from 30 healthy age/sexmatched<br />

controls (Kruskal-Wallis test); and b) analyzed the change in biomarker levels <strong>of</strong> patients<br />

between baseline and 1-3m samples (Spearman test).<br />

Results:When we compared the baseline samples <strong>of</strong> 41 aPL-positive patients (74% female; mean age: 42<br />

± 25; Primary APS: 18; asymptomatic aPL positivity with no SLE:9; APS with SLE: 7; and asymptomatic<br />

aPL positivity with SLE:7) with controls, we found that the levels <strong>of</strong> IL6 (38 vs 0.7 pg/ml), VEGF (225 vs<br />

114 pg/ml), IP10 (584 vs 107 pg/ml); sCD40L (2477 vs 24.7 pg/ml), INFa2 (213 vs 16 pg/ml), IL1ß (4.7 vs<br />

0.4 pg/ml), TNFa 30 vs 0.5 pg/ml), and sTF (134 vs 13 pg/ml) were significantly elevated, but not <strong>of</strong> MCP-<br />

1, IL8 or CRP. Based on the analysis <strong>of</strong> the available follow-up samples, fluvastatin significantly reduced<br />

IL6, IL1ß, TNFa, sTF, sICAM-1, sVCAM, and sE-sel levels within 30-90 days <strong>of</strong> treatment.<br />

Conclusion: Conclusions: Based on the preliminary analysis <strong>of</strong> our ongoing pilot study, fluvastatin 40 mg<br />

daily for 3 months significantly reduced the pro-inflammatory and prothrombotic biomarkers in<br />

persistently aPL-positive patients with or without SLE. These findings: a) underscore the importance <strong>of</strong><br />

identifying aPL-related disease biomarkers; and b) provide further support for the potential beneficial<br />

effects <strong>of</strong> statins in aPL-positive patients justifying future controlled clinical studies.<br />

Effect <strong>of</strong> Omalizumab on Health Care Utilization in Severe Asthmatics<br />

Samir J Patel, MD<br />

Introduction: Poorly controlled asthma is associated with increased health care<br />

utilization. Omalizumab, a monoclonal antibody which blocks IgE, is recommended as an add-on<br />

therapy for patients with moderate-to-severe persistent allergy-related asthma with inadequate<br />

control. Patients require subcutaneous injections every two to four weeks when receiving omalizumab<br />

therapy. While studies have shown reduced exacerbations, need for corticosteroids, and improved<br />

symptom control with use <strong>of</strong> omalizumab, no study has specifically looked at the effect on healthcare<br />

utilization.<br />

Methods: We performed a retrospective, before-and-after study <strong>of</strong> adults receiving omalizumab for<br />

asthma at six military tertiary care centers. Data was obtained through review <strong>of</strong> electronic medical<br />

records <strong>of</strong> identified patients. Total health care visits, asthma-related health care visits, ER visits and<br />

hospitalizations, and doses <strong>of</strong> oral steroids were assessed in the year prior to and year after starting<br />

omalizumab therapy.<br />

Results: Twenty-six patients were included in the analysis including 9 males (35%) and 17 females<br />

(65%). There was a statistically significant increase in the mean number <strong>of</strong> total clinic visits, increasing<br />

from 21.5 to 37.4 in the years prior to and after initiation <strong>of</strong> omalizumab respectively (p=0.003). There<br />

was also a significant increase in the mean number asthma-related clinic visits, increasing from 10.3 to<br />

Female Gender and Low Body Mass Index May Predict a Difficult Radial Arterial Access<br />

Alejandro Velasco MD, Chikako Ono MD, Patrick Tarwater PhD, Kenneth Nugent MD, Ashwani Kumar<br />

MD<br />

Introduction: Radial percutaneous coronary interventions have a lower bleeding rate and shorter time<br />

to recovery than the femoral access. However, small arterial diameters requiring large sheaths can make<br />

complex procedures difficult. No studies in the <strong>American</strong> population have validated the routine use <strong>of</strong><br />

5Fr sheaths. The identification <strong>of</strong> subjects with smaller arterial diameters may be beneficial for planning<br />

cardiac interventions and prevent complications. This study assessed the diameter <strong>of</strong> the radial artery in<br />

the <strong>American</strong> population, analyzed the factors affecting it, and assessed the feasibility <strong>of</strong> using larger<br />

sheaths for radial interventions.<br />

Methods: The right radial arterial diameters were measured using an ultrasound technique in 100 adult<br />

volunteers at our institution. Diameters were measured 1 to 2 cm proximal to the radial styloid process.<br />

A horizontal and vertical diameter was obtained in each radial artery and an average <strong>of</strong> both values was<br />

considered as "average diameter". A logistic regression analysis was performed to identify factors<br />

associated with a diameter smaller than 5Fr.<br />

Results: The mean age <strong>of</strong> subjects was 35 years, 40% subjects were male and the mean body mass index<br />

(BMI) was 27. The mean right average diameter for our entire population was 2.22 ± 0.35 cm. The<br />

diameters ranged from 1.45 to 3.0 cm. The mean right diameter for males was larger (2.42 ± 0.33 cm)<br />

compared to females (2.08 +/- 0.29 cm) (p value

Efficacy <strong>of</strong> pioglitazone on viral kinetics, cytokines, and innate immunity in a group <strong>of</strong> insulin resistant<br />

treatment naïve, genotype 1, chronic hepatitis c patients<br />

Kelvin Bush CPT, MC, USAF (Associate), LTC Stephen A. Harrison, MD (FACP), Karol Barstow, RN,Prashant<br />

Pandya, MD,Michael Charlton, MD<br />

Introduction: Hepatitis C Virus (HCV) infection is an important cause <strong>of</strong> chronic liver disease, cirrhosis<br />

and hepatocellular carcinoma worldwide. Several approaches have been used to predict the disease<br />

progression and therapeutic response in chronic hepatitis (CHC) patients. Insulin resistance (IR), a<br />

condition that precedes the development <strong>of</strong> type 2 diabetes (T2D), has been negatively implicated in<br />

disease progression and response to antiviral therapy. IR reduces the response to interferon alfa-based<br />

therapy <strong>of</strong> CHC patients by theoretically blocking interferon intracellular signaling. The use <strong>of</strong><br />

pioglitazone in addition to combination antiviral therapy has been shown to increase RVR and SVR in<br />

non-genotype 1 patients. In this prospective study our goals were to 1)evaluate the effects <strong>of</strong><br />

pioglitazone on viral kinetics produced by a single dose <strong>of</strong> peginterferon alfa-2b, 2) to assess the impact<br />

<strong>of</strong> pioglitazone on inflammatory cytokine mileu, and 3) to demonstrate pioglitazone induced changes in<br />

intrahepatic gene expression pr<strong>of</strong>iles in insulin resistant, treatment naïve, genotype 1 CHC patients.<br />

Methods: We performed a multicenter, prospective, randomized cohort study on insulin resistant,<br />

treatment naïve, genotype 1, CHC patients (n=16). All study subjects received 1.5mcg/kg peginterferon<br />

alfa-2b at days 0 and 97. The treatment group (n=10) received 90 days <strong>of</strong> pioglitazone 45mg. Liver<br />

biopsy was done before and after treatment with pioglitazone (n=4). Viral load measurements were<br />

obtained at 0, 6, 10, 24 hours, and day 2, 5, 7 following each injection. Gene expression pr<strong>of</strong>iles were<br />

performed on liver samples obtained.<br />

Results: No significant differences in viral kinetics between treatment groups (p=0.18) were found.<br />

Measured serum cytokines were not significantly altered with pioglitazone treatment. Pre and post<br />

differences in nitric oxide signaling apoptosis (p=0.002), leptin activity on JAK/STAT and MAPK cascades<br />

(p=0.009), anti-apoptotic action <strong>of</strong> nuclear ESR1/ESR2 (p=0.009), and nine other gene expressions were<br />

demonstrated.<br />

Conclusion: The addition <strong>of</strong> pioglitazone to peginterferon alfa-2b did not improve viral kinetics in<br />

treatment naïve, insulin resistant, genotype 1, CHC patients in comparison to peginterferon alfa-2b<br />

alone. However, several genes involved with interferon intracellular signaling were significantly<br />

upregulated with pioglitazone. Further studies are warranted to better understand the relationship<br />

between IR and interferon signaling as it relates to CHC.<br />

Effects <strong>of</strong> Illicit Drug use on Clinical Outcome <strong>of</strong> Heart Failure<br />

Capt Ryan C Stoner, MD<br />

Introduction: Illicit drug use is a known etiology for cardiomyopathy. However, prior studies evaluating<br />

decompensated heart failure in illicit drug users have focused primarily on stimulant use and short term<br />

follow-up; thus, a relationship between illicit drug use and long-term clinical outcomes is not well<br />

described. The goal <strong>of</strong> our study was to describe characteristics <strong>of</strong> heart failure patients who used illicit<br />

drugs, and to determine the effects <strong>of</strong> illicit drug use on clinical outcomes such as in-hospital mortality<br />

and hospital readmission for heart failure.<br />

Methods: We reviewed data collected for The Joint Commission in patients admitted with heart failure<br />

at a university hospital serving an indigent high-risk population in Louisiana during the period from June<br />

2003 to September 2004. Patients were divided into 2 groups: illicit drug use and no illicit drug use<br />

groups based on self-reported use and positive laboratory results. Outcome measures were in-hospital<br />

mortality, heart failure readmission rate, time to readmission for heart failure, and average brain<br />

natriuretic peptide (BNP) and troponin levels throughout the follow-up period.<br />

Results: Of 646 reviewed records, 542, representing 357 patients, were included in the analysis. There<br />

were 53 patients in the illicit drug use and 304 in the no illicit drug use group. Mean (standard deviation)<br />

<strong>of</strong> follow up period was 2.39 (1.6) years. Kaplan-Meier log-rank analysis demonstrated that illicit drug<br />

use was associated with shorter time to readmission for heart failure (p< 0.0001, HR 3.8, 95% CI 2.3-<br />

10.7); Multiple linear regression analysis identified illicit illicit drug use as an independent variable for<br />

heart failure readmission rate (parameter estimate = 0.71; p=0.0001). We found no significant<br />

difference in in-hospital mortality (p= 0.42), average troponin-I levels (p=0.4), or higher average BNP<br />

levels (p= 0.36).<br />

Conclusion: This study demonstrated that illicit drug use was associated with higher heart failure<br />

readmission rates and decreased time to readmission for heart failure. In the era <strong>of</strong> the patientcentered<br />

care, this study provides a mandate for increased community-based initiatives to mitigate the<br />

problem <strong>of</strong> illicit drug use among indigent populations and improve appropriate utilization <strong>of</strong> limited<br />

medical resources.<br />

Introduction: Pertussis, a vaccine-preventable illness, has had a resurgence in the past several years. In<br />

2009 alone, there were 16,858 cases and 12 deaths due to pertussis in the United States. Adults with<br />

waning immunity are at risk <strong>of</strong> developing disease and then transferring it to unvaccinated infants.<br />

Women <strong>of</strong> child-bearing age and adults with expected infant contact are an important potential source<br />

<strong>of</strong> infection. Recent infant deaths and outbreaks led to new Tdap vaccine recommendations in 2010,<br />

expanding coverage to include adults older than 65 who may have infant contact, and considering it in<br />

all adults over 65. Time limitations were removed, allowing for administration <strong>of</strong> Tdap regardless <strong>of</strong><br />

when the last tetanus- or diphtheria-containing vaccination was given. Despite these changes,<br />

vaccination rates remain strikingly low. A performance improvement (PI) project was developed to<br />

improve Tdap coverage at Walter Reed National Military Medical Center in an effort to decrease<br />

morbidity and mortality from pertussis.<br />

Methods: The PI project targeted the high risk population <strong>of</strong> women <strong>of</strong> child-bearing age and other<br />

adult females. Women seen in the Gynecology Clinic had their electronic medical record (EMR) screened<br />

for Tdap as part <strong>of</strong> a routine vital signs assessment. Those eligible for vaccination were given a handout<br />

with instructions on how to get the Tdap administered in the Immunization Clinic. Data was collected<br />

from December 2010 to April 2011, and vaccination rates were determined one month before and after<br />

the start <strong>of</strong> the PI project. Vaccination was considered a result <strong>of</strong> the intervention if it was received<br />

within one month <strong>of</strong> the appointment.<br />

Results: There were 1421 visits prior, and 881 following the PI project. Only 13% <strong>of</strong> all patients had a<br />

documented Tdap at any time point. Following the intervention, vaccination rates increased from 0.38%<br />

to 6.5% and patients were 19 times (95% CI: 7%-47%, P

Statins Effects on the Incidence <strong>of</strong> Infection<br />

John Magulick, Capt, USAF, MC (Associate), Christopher Frei, PharmD Sayed Ali, MD (Member), Ishak<br />

Mansi, MD (FACP)<br />

Introduction: Despite their cardiovascular benefits, the effects <strong>of</strong> statin therapy on the incidence and<br />

severity <strong>of</strong> infection remain unclear. While some observational studies suggest that statins protect<br />

against infections and improve clinical outcomes, other studies suggest an opposite or no effect. Some<br />

investigators suggest the studies that demonstrated improved outcomes in statin users are attributable<br />

to “healthy user bias,” and statin use may be a surrogate marker for better patient care. Our objective<br />

was to further investigate the incidence <strong>of</strong> infection in statin users compared to non-users within the<br />

same healthcare system.<br />

Methods: A retrospective cohort study <strong>of</strong> all patients in the San Antonio military multi-market was<br />

performed from 1 October 2003 through 5 March 2010. Inpatient and outpatient ICD-9 codes were<br />

compared between statin users and non-users. Statin users were defined as patients who received a<br />

statin for at least 3 months between 1 October 2003 and 30 September 2004. Statin non-users were<br />

defined as patients who did not receive a statin within the study period. The incidence <strong>of</strong> all infections<br />

[ICD-codes: 001-139 (all infections); 795.3 (non-specific positive culture); and 795.5 ( positive PPD)] as<br />

well as subtypes <strong>of</strong> infection (bacterial, viral, fungal and parasitic) were compared using multivariate<br />

regression analysis between the two groups.<br />

Results: Of 92,360 identified beneficiaries, 12,980 were statin users and 45,997 were non-users. After<br />

adjustment for age, gender and the Charlson comorbidity index, there was no difference in the<br />

incidence <strong>of</strong> infections between the two groups in the outpatient setting (odds ratio (OR): 0.98; 95%-CI:<br />

0.92-1.05). However, the incidence <strong>of</strong> infection in hospitalized patients was lower in statin users<br />

compared to non-users (OR: 0.58; 95%-CI: 0.37-0.90). Analysis <strong>of</strong> infection subtypes in the outpatient<br />

setting revealed no significant difference in the incidence <strong>of</strong> bacterial (OR: 0.98; 95%-CI: 0.92-1.05), viral<br />

(OR: 0.91; 95%-CI: 0.79-1.04), or fungal and parasitic (OR: 1.0; 95%-CI: 0.93-1.07) infections.<br />

Conclusion: Statin use was associated with a lower incidence <strong>of</strong> infection in hospitalized patients, but<br />

not in the outpatient setting. Furthermore, statin use was not associated with a difference in incidence<br />

<strong>of</strong> bacterial, viral or fungal and parasitic infections in the outpatient setting.<br />

Dermatology Clinic Time Motion Study and Monte Carlo Method Simulation to Optimize Clinic<br />

Justin M Stinnett-Donnelly, MD, Stephanie Mariorenzi, Abigail Trutor, MBA<br />

Introduction: Montecarlo simulation is a useful tool to evaluate hypothesis for optimizing clinic<br />

schedules. No single schedule optimized efficiency parameters <strong>of</strong> both MD’s and patients. Decreasing<br />

no-show rates has a paradoxical effect <strong>of</strong> increasing throughput while worsening schedule<br />

performance. This is due to no-shows allowing random catch up during the day.<br />

Methods: Time and motion analysis was conducted in June 2011. 56 half day clinics, 9 physicians<br />

observed with 550 patient encounters. Timestamps were taken in the following order: a) medical<br />

assistant (MA) and patient enter room, b) MA leaves room c) resident enters room (if resident available)<br />

d) resident leaves room e) physician (MD) enters room f) MD exits room. No show and same day<br />

cancelations were recorded. All observations were attained outside the exam room for patient<br />

confidentiality. The mean time MA and MD spend with the patient by appointment length were<br />

calculated.<br />

Montecarlo clinic simulation was conducted using the data from the time motion analysis and estimate<br />

<strong>of</strong> patient waiting room arrival characteristics. With this computer algorithm two different analyses<br />

were undertaken: 1) Eight different morning schedules were evaluated with 4 fifteen and thirty minute<br />

appointment slots each. The iterative model ran 10K times and the mean waiting time <strong>of</strong> the patient,<br />

MA and MD was recorded for each step in the visit. The schedule which minimized patient waiting and<br />

clinic end times was considered most efficient. The second analysis 2) evaluated the effect <strong>of</strong> no show<br />

rates on schedule efficiency. The most efficient schedule was run 10K times varying no show rates from<br />

0% to 12%. Efficiency was again defined as minimum patient wait times and end time <strong>of</strong> AM clinic.<br />

Results: Mean (StDev) MA time for 15 and 30 minute appointments was 4.34(6.07) and 4.62(2.92)<br />

minutes respectively. MD time with patient was 14.16(8.56) and 18.92(11.19). No Show appointments<br />

were 11.64% <strong>of</strong> appointments. Under Montecarlo simulation mean wait in waiting room varied from<br />

[0.8-1.9] minutes, wait in exam room was [2.6-3.4] minutes and mean time that clinic ended ranged<br />

[11:58am-12:13pm]. No show variation resulted in an inverse relationship to patient weight times,<br />

increasing patient exam room wait from 2.8 to 3.4 minutes and clinic end from 12:00 to 12:05pm.<br />

Conclusion: Montecarlo simulation is a useful tool to evaluate hypothesis for optimizing clinic<br />

schedules. No single schedule optimized efficiency parameters <strong>of</strong> both MD’s and patients. Decreasing<br />

no-show rates has a paradoxical effect <strong>of</strong> increasing throughput while worsening schedule<br />

performance. This is due to no-shows allowing random catch up during the day.<br />

Fresh Frozen Plasma Dosing For Warfarin Reversal: A Handy Formula<br />

1. Armin Rashidi, MD: Department <strong>of</strong> Internal Medicine, Eastern Virginia Medical School, Norfolk, VA 2.<br />

H. Raymond Tahhan, MD: Departments <strong>of</strong> Pathology and Internal Medicine, Eastern Virginia Medical<br />

School, Norfolk, VA<br />

Introduction: Fresh frozen plasma (FFP) administration is the most common method <strong>of</strong> warfarin<br />

reversal. Currently, FFP dosing is not evidence-based and different societies propose different<br />

guidelines. The purpose <strong>of</strong> the present study is to derive an easy-to-use formula in the form <strong>of</strong> DeltaINR<br />

(i.e. PreINR – PostINR) = a x preINR + b, where a and b are constants, postINR is the INR after<br />

administration <strong>of</strong> one unit <strong>of</strong> FFP, and preINR is the INR before FFP administration.<br />

Methods: In a retrospective study (March 2009-March 2011), we review the data <strong>of</strong> all patients for<br />

whom a total <strong>of</strong> 13,000 units <strong>of</strong> FFP has been released by the transfusion service in our institution. We<br />

exclude patients with disseminated intravascular coagulation or liver disease, pregnant women, and<br />

those who received recombinant factor VII or prothrombin complex concentrate. We use multivariate<br />

regression for analysis, in which DeltaINR is the outcome variable and preINR is the main predictor.<br />

Potential covariates in the model are age, sex, ideal body weight, whether or not vitamin K was<br />

administered, and the timing <strong>of</strong> postINR relative to the time <strong>of</strong> FFP administration. We first find the<br />

formula for the subset <strong>of</strong> patients that received only one unit <strong>of</strong> FFP. Next, we apply the formula from<br />

the previous step, in a stepwise manner, to the subset that received 2, 3, 4, or 5 units <strong>of</strong> FFP. Finally,<br />

predicted values <strong>of</strong> DeltaINR are compared with actual values.<br />

Results: To date, we have reviewed 5,715 cases, <strong>of</strong> which 769 have met the inclusion criteria. The best<br />

estimate for DeltaINR after one unit <strong>of</strong> FFP (n = 270) is 0.6 x preINR - 0.7 (R 2 =83%, p < 0.001). Including<br />

additional variables in the model does not increase the predictive power <strong>of</strong> the model. Applying the<br />

model to the subset who received two units <strong>of</strong> FFP (n = 377) reveals a strong correlation between<br />

predicted and actual values <strong>of</strong> DeltaINR (R 2 =92%, p < 0.001).<br />

Conclusion: Our formula provides an easy method to calculate how many units <strong>of</strong> FFP are required to<br />

reverse INR to the desired level. It is also the most accurate formula available for this purpose and may<br />

become the standard <strong>of</strong> care.<br />

Proton Pump Inhibitor use in a Large Outpatient Clinic Population<br />

William Hood DO Alicia Warnock DO Aditi Girme MD Nelson Smith DO Brandon Robinson DO Brittain<br />

McJunkin MD FACP<br />

Introduction: Proton pump inhibitors (PPIs) have replaced histamine-2 receptor antagonists (H2RAs) as<br />

first line therapy for gastroesophageal reflux disease (GERD) and other acid-related disorders. PPIs have<br />

become the third most prescribed category <strong>of</strong> medications in the US. Concerns have been raised<br />

regarding PPI overuse, potential adverse effects and drug interactions, and costs. In this regard, we<br />

undertook a study in our large outpatient internal medicine clinic, mainly to assess issues <strong>of</strong> proper<br />

utilization and costs.<br />

Methods: Two hundred-fifty-nine randomly selected medical records were reviewed. The percentage <strong>of</strong><br />

patients receiving PPIs during the year 2009 was determined. Source <strong>of</strong> prescriptions and duration <strong>of</strong><br />

treatment was assessed. Diagnosis for PPI use was determined based on history and/or upper<br />

endoscopy findings. In patients with GERD diagnosis, documentation <strong>of</strong> history details was determined.<br />

H2RA use was also evaluated, as well as prescribing for aspirin, NSAIDs, and clopidogrel.<br />

Results: A total <strong>of</strong> 259 outpatient clinic patient records were reviewed, mean age 52.6 (19-99), 55.6%<br />

female, 92% Caucasian. During 2009, 83 (32.5%) were taking PPIs. Original source <strong>of</strong> PPI prescription<br />

was unclear in 54 (65.0%). GERD was listed as the primary diagnosis in 83.1% <strong>of</strong> PPI patients. History<br />

consistent with GERD was obtained in 29 (34.9%), and/or endoscopy proven GERD was confirmed in 28<br />

(33.7%). In those with recorded GERD history, symptom severity (i.e. frequency, intensity <strong>of</strong> symptoms,<br />

and nocturnal symptoms) was obtained in 32.6%. “Abdominal pain” was a listed diagnosis in 27<br />

(32.5%), along with other non-specific complaints. Peptic ulcer disease was recorded in 2.4%. H2RAs<br />

were used in 28 (10.8%) <strong>of</strong> all patients, 4 in patients taking a PPI. NSAIDS were used concomitantly with<br />

PPIs in 24.1%, low-dose ASA with PPI in 50.6%, ASA/Plavix with PPI in 9.6%. In no patients was<br />

gastroprotection listed as reason for PPI use.<br />

Conclusion: PPIs were used in one-third <strong>of</strong> our clinic patient population during 2009. “GERD” was the<br />

most commonly listed diagnosis in PPI patients, but documented in only one-third. History <strong>of</strong> GERD<br />

symptoms was usually not adequate to determine symptom severity, i.e. whether inexpensive/lowadverse<br />

effect H2RA therapy would be appropriate as initial treatment in those with only mild to<br />

moderate symptoms. Other indications for PPI use, including gastroprotection in certain ASA/NSAID<br />

pts., were commonly unclear or not provided. Hence, in our clinic, PPI prescribing indications are vague,<br />

PPI use may be excessive, and H2RA therapy is probably underutilized. Quality improvement initiatives<br />

have been undertaken to ensure appropriate PPI use, obviate potential PPI adverse effects, and to lower<br />

costs.<br />

Improving Patterns <strong>of</strong> Urinary Catheter Use<br />

Cynthia E Collins, DO Second Author: Molly John, MD Third Author: Heather Grome, BS Fourth Author:<br />

Stephanie Thompson, PhD<br />

Introduction: An estimated 4 million patients receive urinary catheters annually and are exposed to<br />

catheter associated complications. Thirty percent <strong>of</strong> health care associated infections are UTI, 80% <strong>of</strong><br />

which are associated with urinary catheter use. Thus, catheter associated UTIs (CAUTI) compromise<br />

patient health and increase hospital costs and lengths <strong>of</strong> stay. While rates <strong>of</strong> death and serious<br />

complications due to catheterization is generally low, the high frequency <strong>of</strong> catheter use in hospitalized<br />

patients causes the burden <strong>of</strong> catheter associated urinary tract infections (CAUTI) to be substantial for<br />

healthcare systems. The goal <strong>of</strong> our study is to retrospectively examine urinary catheter use at CAMC in<br />

general medical patients older than 50 years. We will determine the patterns <strong>of</strong> urinary catheter use,<br />

complication rates and indications for catheter placement in the patient group. This information will be<br />

used to determine if and where education should be targeted to decrease excessive urinary catheter<br />

use.<br />

Methods: This retrospective study looked at general medicine patients aged 50 years and older<br />

admitted to CAMC from 3/1/2010 to 9/30/2010. Patients under 50 years <strong>of</strong> age, admitted to the ICU,<br />

presenting with indwelling urinary catheters, trauma patients, or who have an attending physician who<br />

is not associated with CAMC hospitalist or Internal Medicine Department were excluded.<br />

Results: Of the 7919 patients meeting the inclusion criteria, 1792 received a catheter (23%) The<br />

average age for catheter was 73yrs versus 69yrs for no catheter. Average length <strong>of</strong> stay was 4.5 days for<br />

no catheter and 6.9 days with catheter. In the catheter subgroup, 9 <strong>of</strong> 162 had a documented UTI after<br />

receiving urinary catheter. Similar to other studies, we found catheter placement more likely in female,<br />

elderly patients. The majority <strong>of</strong> patients received the catheter in the ED (56%) before transferring to<br />

the medical floor. The average length <strong>of</strong> catheter placement was 4 days.<br />

Conclusion: Limiting catheter use is important in helping to decrease the number <strong>of</strong> CAUTI. Strategies<br />

that have been shown to be beneficial include physician reminders by nurses and electronic reminders<br />

that a catheter was placed in the ED. We now have computerized physician order entry and nurses<br />

clinical assessment in place. Nurses are required to assess if the catheter use is appropriate and<br />

recommend removal if not needed as part <strong>of</strong> their clinical assessment. We are working to make the<br />

indications for a catheter a mandatory part <strong>of</strong> ordering. We plan to go back and collect the same data<br />

after these changes are in place.<br />

The Impact <strong>of</strong> Automated Protocol in Management <strong>of</strong> Diabetic Ketoacidosis (DKA)<br />

Adam H Maghrabi, MD<br />

Introduction: DKA is characterized by the triad <strong>of</strong> hyperglycemia, ketonemia and metabolic acidosis.<br />

DKA can potentially result in significant morbidity and mortality DKA hospital admissions and<br />

management poses a huge economic burden to health care delivery system. Fluid, insulin and potassium<br />

replacement are among the primary important factors in the management <strong>of</strong> DKA.<br />

Our aim is to determine the effect <strong>of</strong> implementation <strong>of</strong> an automated protocol for management <strong>of</strong><br />

Diabetic Ketoacidosis (DKA).<br />

Methods: Our study is a retrospective chart review <strong>of</strong> DKA patients managed one year before and after<br />

the automated DKA protocol implementation at a tertiary care hospital. Patient’s medical records and<br />

laboratory data base were reviewed.<br />

Results: There were 88 patients managed one year prior (control group) and 70 patients managed one<br />

year after the implementation <strong>of</strong> automated DKA protocol (study group). Total time required for<br />

resolution <strong>of</strong> the DKA was significantly shorter in the study group compared to the control group [11.5<br />

(8.1-17.1) hours vs. 8.5 (5.8-12) hours, P = 0.0078]. Hypoglycemic events were significantly lower in the<br />

study group as compared to the control group [P = 0.029]. There was no difference in the potassium<br />

abnormalities and rate <strong>of</strong> decline <strong>of</strong> glucose. On a 1-10 scale survey, most <strong>of</strong> the nurses and doctors<br />

found the protocol safe, and effective for prompt communication among them.<br />

Conclusion: Our study showed that implementation <strong>of</strong> an automated protocol reduced the DKA<br />

resolution time and hypoglycemic events without compromising electrolyte imbalance.<br />

Possible Mechanism <strong>of</strong> Fish Oil's Cardiac Benefits.<br />

Dajun Wang MD<br />

Introduction: Heart failure is the leading reason for hospital admissions and is the most expensive<br />

Medicare expenditure. About half <strong>of</strong> heart failure cases are due to diastolic dysfunction. One <strong>of</strong> the main<br />

causes <strong>of</strong> diastolic dysfunction is cardiac fibrosis. Previous study demonstrated that Omega-3<br />

polyunsaturated fatty acids [?-3 PUFAs, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA)]<br />

prevent overload-induced cardiac fibrosis and cardiac dysfunction by blocking TGF-ß1-induced phospho-<br />

Smad2/3 nuclear translocation through activation <strong>of</strong> the cGMP/PKG pathway in cardiac fibroblasts.<br />

Previous study also demonstrated that in cardiac fibroblast, EPA and DHA increase cGMP levels by<br />

increasing phospho-eNOS and eNOS protein levels and nitric oxide production. Caveolin is the principal<br />

structural protein in caveolae, which interacts with endothelial NOS (eNOS) and leads to eNOS<br />

inhibition. Therefore, we tested the hypothesis that EPA and DHA decrease Caveolin expression in<br />

cardiac fibroblasts.<br />

Methods: Confluent cultures <strong>of</strong> adult mouse cardiac fibroblasts in 6-cm collagen-coated plates were<br />

incubated in the presence or absence <strong>of</strong> the indicated control, DHA or EPA for 24 hours. Western Blot<br />

analysis was carried out to determine protein levels <strong>of</strong> Caveolin and GAPDH. GAPDH was used as the<br />

internal control.<br />

Results: Compared with control, DHA (10 mM) and EPA (10 mM) significantly reduced Caveolin/<br />

GAPDH ratio in cardiac fibroblasts (72% and 65% reduction, respectively P

Autoimmune Pancreatitis as a Manifestation <strong>of</strong> IgG4-related Systemic Disease<br />

Maria E Andrae-Hammond, MD<br />

INTRODUCTION: Autoimmune pancreatitis (AIP) is an increasingly recognized form <strong>of</strong> chronic<br />

pancreatitis. Its presentation <strong>of</strong>ten mimics pancreatic cancer; however, it responds dramatically to<br />

steroid therapy. Autoimmune pancreatitis is diagnosed by characteristic clinical, serological,<br />

morphological and histopathological features and appears to represent one manifestation <strong>of</strong> IgG4related<br />

systemic disease (IgG4-RSD).<br />

CASE PRESENTATION: A 75-year-old Chinese man with a past medical history <strong>of</strong> allergic rhinitis,<br />

remote partial gastrectomy, chronic Hepatitis C and recent right-sided submandibular mass presented<br />

with anorexia, abdominal pain and low-grade fever. He was moderately tender to palpation over the<br />

epigastrium and had elevated amylase (222) and lipase (505) levels. CT abdomen demonstrated mild<br />

congestion <strong>of</strong> the posterior pancreas, infiltrative lesions within the kidneys and abnormal thickened s<strong>of</strong>t<br />

tissue around the abdominal aorta indicative <strong>of</strong> aortitis. Abdominal ultrasound demonstrated a focal 3cm<br />

hypoechogenic lesion in the pancreatic body, suspicious for neoplasm. These findings, together with<br />

the biopsy report <strong>of</strong> the right submandibular gland indicating fibrosing sialadenitis with markedly<br />

increased numbers <strong>of</strong> IgG4 positive cells, suggested the clinical diagnosis <strong>of</strong> IgG4-RSD, supported by an<br />

elevated ESR <strong>of</strong> 75, + RF, +ANA, + anti dsDNA, and a high normal IgG level. The patient was treated with<br />

prednisone 30 mg twice daily; lipase levels normalized and clinical symptoms subsided. After several<br />

weeks prednisone was tapered and the patient was maintained at 10 mg daily. Abdominal MRIs at 2<br />

months and 6 months demonstrated resolving inflammatory aortitis as well as disappearance <strong>of</strong> the<br />

pancreatic mass.<br />

DISCUSSION: Autoimmune pancreatitis is a rare disease, first described in Japan in the 1990’s. It is<br />

twice as common in men as in women, and most patients are older than 50. Multiple organs, including<br />

the pancreas, biliary tree, salivary glands, kidneys, lungs, aorta, colon and thyroid glands, can be<br />

affected simultaneously but more <strong>of</strong>ten metachronously, with striking histopathologic similarities. This<br />

has led to the concept <strong>of</strong> IgG4-RSD, for which the exact pathophysiologic mechanisms are still unknown.<br />

Diagnostic criteria in the US are based on histological, imaging and serological characteristics as well as<br />

extrapancreatic involvement. Patients present with abdominal pain, with or without frequent attacks <strong>of</strong><br />

pancreatitis (30%), obstructive jaundice (63%), diffuse enlargement <strong>of</strong> the pancreas on CT and US (85%)<br />

mimicking pancreatic carcinoma, and/or narrowing <strong>of</strong> the pancreatic duct. Important markers include<br />

elevated serum IgG4 levels to > twice normal, anti–PBP peptide and carbonic anhydrase II and<br />

lact<strong>of</strong>errin antibodies. ANA or RF can also be found.<br />

Corticosteroids alleviate symptoms, decrease the size <strong>of</strong> the inflamed pancreas and reverse histologic<br />

changes. Incomplete responses, flares or relapses on steroid therapy can be treated with azathioprine,<br />

methotrexate, mycophenolate m<strong>of</strong>etil, cyclophosphamide and B-lymphocyte-depletion drugs such as<br />

rituximab.<br />

A Case <strong>of</strong> Uninhibited Inhibition: Opposition to Factor VIII<br />

Andrew D Timothy, DO, MS Du Thuy Tran, PharmD Arjun Mohan, MD Sharad Virmani, MD<br />

INTRODUCTION: Acquisition <strong>of</strong> autoantibodies to Factor VIII (FVIII) is a rare entity, occurring at a rate<br />

<strong>of</strong> less than 1 case per million per year. Potential hemorrhagic complications are estimated to be fatal in<br />

14-22% <strong>of</strong> cases. With limited evidence on treatment, eradication <strong>of</strong> FVIII inhibitors remains<br />

challenging.<br />

CASE PRESENTATION: A 55-year-old Caucasian male with a history <strong>of</strong> bladder cancer presented with a<br />

progressively painful mass in the left posterior calf over the course <strong>of</strong> one-week associated with<br />

increasing pain affecting ambulation. Patient admitted to the use <strong>of</strong> a fluoroquinolone for a URI twodays<br />

prior. Physical exam revealed a blood pressure <strong>of</strong> 98/68, heart rate <strong>of</strong> 101 bpm, ecchymosis on the<br />

left upper arm, swelling and tenderness in the left calf with 4/5 weakness in the left-lower extremity and<br />

reduced range <strong>of</strong> motion at the knee. Preliminary labs revealed a hemoglobin <strong>of</strong> 6.6 g/dL and an<br />

activated partial thromboplastin time 74.4 seconds. A CT <strong>of</strong> the left leg with contrast confirmed a 12 x<br />

9.4 cm intramuscular hematoma involving the soleus and gastrocnemius muscles. Subsequent mixing<br />

study revealed near correction <strong>of</strong> PTT. Measured FVIII was deficient at 11%. Intermittent and<br />

continuous infusions <strong>of</strong> recombinant FVIII resulted in further decline <strong>of</strong> FVIII at 6%. A high inhibitor titer<br />

was documented at 17 Bethesda Units (BU), confirming the presence <strong>of</strong> FVIII inhibitors. Multiple<br />

transfusions <strong>of</strong> packed red blood cells and cryoprecipitate were required due to substantial s<strong>of</strong>t-tissue<br />

bleeds during hospital stay. A prolonged course <strong>of</strong> high-dose intravenous corticosteroids combined with<br />

two trials <strong>of</strong> high-dose intravenous immunoglobulin (IVIG) paradoxically yielded an increased inhibitor<br />

titer to 29 BU. A trial <strong>of</strong> Rituximab was initiated; however hypotension secondary to hemorrhagic<br />

complications prematurely ended this regimen. A left-sided retroperitoneal hematoma, sub-acute<br />

compartment syndrome <strong>of</strong> the left arm and recurrent hematuria occurred successively during<br />

hospitalization. Attempts to restore hemostasis were unsuccessful and the patient expired soon after.<br />

DISCUSSION: Derivation <strong>of</strong> autoantibodies to FVIII is cryptogenic in half <strong>of</strong> reported cases, with<br />

remaining causes stemming from autoimmune diseases, medications, post-partum period, or<br />

malignancies. With a negative autoimmune work-up in our patient, presence <strong>of</strong> FVIII inhibitors were<br />

potentially attributed to recent fluoroquinilone use and/or his underlying malignancy. Treatment with<br />

cyclophosphamide was avoided in this case because <strong>of</strong> cytotoxic toxicities including hemorrhagic<br />

cystitis. Inhibitor clearance with steroids may achieve remission in 30% <strong>of</strong> cases while there is a<br />

reported 50% response rate to high-dose IVIG. Reports <strong>of</strong> Rituximab utilization have demonstrated a<br />

clinical response within a week. This case emphasizes the elusive nature <strong>of</strong> autoantibodies targeting<br />

FVIII and resistance to multi-treatment eradication therapy.<br />

Levamisole-Induced Pseudovasculitis<br />

Mudita Bhugra, MBBS Samih Mawari,MD Swapna Devanna,MD Thamilvani Thiruvasahar,MD Anne<br />

Miller,MD<br />

INTRODUCTION: Levamisole was initially discovered as an anti-helminthic agent in the 1960s. It was<br />

subsequently found to have immunomodulatory effects and was used in the treatment <strong>of</strong> nephrotic<br />

syndrome, colon cancer, and rheumatoid arthritis. Recently, attention has been focused on the use <strong>of</strong><br />

levamisole as a cutting agent in cocaine, and linked to cutaneous vasculitis.<br />

CASE PRESENTATION: JS is a 50 Year old male with history <strong>of</strong> polyarthralgia who was admitted with a<br />

rash for two days that initially appeared around his ears and nose and then became generalized. It was<br />

associated with severe burning pain in the involved areas. His vital signs were stable at presentation.<br />

Examination revealed extensive, deep purple, non blanching, reticular purpura with early blistering at<br />

the ear lobes, tip <strong>of</strong> the nose, upper thighs and small scattered areas. Lab testing was remarkable for a<br />

WBC count <strong>of</strong> 2.4 K/cumm (3.4-9.4) with an absolute neutrophil count <strong>of</strong> 1.2 K/cumm (1.8-6.5) and urine<br />

toxicology screen positive for cocaine. Based on the reticular pattern <strong>of</strong> rash and urine toxicology<br />

screen, cocaine induced pseudovasculitis was suspected. Further investigation revealed positive<br />

serology for antinuclear antibody (ANA) with a titer <strong>of</strong> 1:160 in a diffuse homogenous pattern,<br />

antineutrophilic cytoplasmic antibodies (ANCA) positive for both MPO and PR3 with a titer <strong>of</strong> >1:640 ,<br />

and high anticardiolipin IgM antibody. Skin biopsy demonstrated widespread thrombosis <strong>of</strong> cutaneous<br />

and subcutaneous blood vessels consistent with levamisole-induced pseudovasculitis. The patient was<br />

treated supportively with fluids, pain medications and later had extensive debridement and skin<br />

grafting. During the course <strong>of</strong> hospitalization he also developed a Coombs positive warm autoantibody<br />

hemolytic anemia for which he was discharged on tapering doses <strong>of</strong> steroids.<br />

DISCUSSION: Levamisole was first reported to cause vasculitis associated with a livedoid rash in 1978 in<br />

a patient with rheumatoid arthritis. Similar necrotizing vasculitis was reported on earlobes in children<br />

receiving levamisole for nephrotic syndrome. Levamisole- induced pseudovasculitis refers to<br />

pathological findings <strong>of</strong> fibrin thrombi and hemorrhage within the blood vessel. It is usually localized to<br />

skin but may also involve internal organs. It causes agranulocytosis leaving the patients susceptible to<br />

opportunistic infections and is associated with autoantibody production including ANA, ANCA and lupus<br />

anticoagulant (LAC). It enhances T cell activation and proliferation, and increases neutrophil mobility<br />

and adherence. Diagnostic clues for levamisole- induced pseudovasculitis/vasculitis are leucopenia/bone<br />

marrow suppression, positive ANA, ANCA, ACL, characteristic pathology and detection <strong>of</strong> cocaine in the<br />

urine. However, diagnosis is a challenge, as most patients withhold the information <strong>of</strong> cocaine use.<br />

Differentiating levamisole associated pseudovasculitis from other types <strong>of</strong> primary and secondary<br />

vasculitis is necessary as conventional treatment is usually ineffective without abstinence from cocaine<br />

and it may be associated with significant morbidity and mortality.<br />

Thrombocytopenia after Blood Transfusion<br />

Emad Uddin Abdul Samad hakemi, MD, Mousami Shah, MD<br />

INTRODUCTION: Post Transfusion Purpura (PTP) is a rare but known reaction to blood transfusions.<br />

Infrequency and lack <strong>of</strong> readily available diagnostics render the recognition challenging and emphasizes<br />

the importance <strong>of</strong> clinical judgment.<br />

CASE PRESENTATION: A 46 year-old African <strong>American</strong> female presented to our hospital with 2 months<br />

shortness <strong>of</strong> breath on exertion. Physical exam was unremarkable except for severe conjunctival and lip<br />

pallor. She was found to have a Hemoglobin (Hb) level <strong>of</strong> 4.6 gm/dl. Further work up <strong>of</strong> her anemia<br />

revealed iron panel and ferritin levels consistent with severe iron deficiency anemia. She reported<br />

previous history <strong>of</strong> heavy menstrual periods and imaging with pelvic ultrasound revealed uterine fibroid<br />

tumors. She responded well to packed red blood cells (PRBC) transfusions on the day <strong>of</strong> admission and<br />

her Hb remained stable during the rest <strong>of</strong> her hospital stay. On admission she had a normal platelet<br />

count which gradually decreased till reaching a nadir <strong>of</strong> 27,000 / microliter over the course <strong>of</strong> 9<br />

consecutive days. She had no detectable active bleeding as supported by her stable Hb levels. Review <strong>of</strong><br />

her medications revealed two possible culprits including heparin and ranitidine, both were stopped but<br />

platelet counts continued to drop. Heparin Induced Thrombocytopenia (HIT) was less likely after HIT<br />

antibodies were not detected in her serum. No evidence <strong>of</strong> sequestration could be found and her spleen<br />

was normal in size as shown in a computed tomography (CT) <strong>of</strong> her abdomen done on the same<br />

admission. In view <strong>of</strong> her recent blood transfusions and negative work up for other possible causes <strong>of</strong><br />

her developing thromobocytopenia, PTP became more likely. Tests for antibodies against platelet<br />

antigens were sent and patient was started on a 500 mg/kg dose <strong>of</strong> empirical intravenous<br />

immunoglobulin (IVIG). Platelet counts stabilized after two doses <strong>of</strong> IVIG and increased to near normal<br />

levels just before her discharge. Laboratory results came back and revealed the presence <strong>of</strong> antibodies<br />

against Human Platelet Antigen-1A (HPA-1A) in her serum, which confirmed the diagnosis <strong>of</strong> PTP.<br />

DISCUSSION: PTP is a rare alloimmune induced thrombocytopenia disorder with a mortality rate <strong>of</strong> 10-<br />

20%. Patients are initially sensitized to platelet antigens in previous pregnancies or blood transfusions.<br />

The most reported is Human Platelet Antigen-1A. PTP occurs if a HPA-1A negative recipient is transfused<br />

with blood from a HPA-1A positive donor, which boosts antibodies production causing consumption <strong>of</strong><br />

both the donor and recipient’s platelets. The mechanism by which circulating antibodies also affect<br />

recipient’s platelets is not clear, multiple theories are yet to be proven including the” innocent by<br />

stander” theory in which the recipient’s platelets adsorb the immune complexes and get destroyed.<br />

Detecting circulating antibodies against platelet antigens and proving that patient’s platelets are devoid<br />

<strong>of</strong> the antigen confirms the diagnosis. Usually results are not readily available so physician’s clinical<br />

judgment plays a major role in initiating effective medical therapy with IVIG. Other less effective<br />

therapeutic modalities include high dose corticosteroids and exchange transfusions. Transfusion <strong>of</strong> HPA-<br />

1A negative platelets is not effective.<br />

Anaplasmosis: a case report and series in suburban Massachusetts<br />

Rattanaporn Mahatanan, MD, Felipe Barbosa, MD, Thomas Treadwell, MD<br />

INTRODUCTION: Human granulocytic anaplasmosis (HGA) is an emerging tick-borne infectious disease<br />

caused by Anaplasma phagocytophilum . The clinical manifestations <strong>of</strong> HGA range from a mild febrile<br />

illness to severe infection with multi-organ system failure. The number <strong>of</strong> cases has been increasing for<br />

the past several years, particularly in suburban Massachusetts. We report a case <strong>of</strong> severe sepsis caused<br />

by anaplasmosis and a series <strong>of</strong> fourteen cases seen in our institution in the last 12 months.<br />

CASE PRESENTATION: A 78 year-old man with history <strong>of</strong> diabetes presented to Metrowest Medical<br />

Center in June 2011 with generalized weakness for 2 days. On admission, hypotension and hypothermia<br />

(94.3 F) were present. The physical exam was remarkable for<br />

dehydration and an ejection murmur grade 2/6 at the apex. No<br />

splenomegaly or rash was noted. He lives in Framingham, MA<br />

and works in his back yard frequently. Initial laboratory data<br />

showed a white blood count <strong>of</strong> 7.2 /mm3 with 83% neutrophils,<br />

7% bands, and platelets <strong>of</strong> 29,000/mm3. Hyperkalemia, mild<br />

elevations <strong>of</strong> the liver enzymes, and acute severe renal failure<br />

(creatinine <strong>of</strong> 15.7 mg/dL) were noted. . The patient received<br />

fluids and broad-spectrum antibiotics, including doxycycline, by<br />

vein. On the day <strong>of</strong> admission, a review <strong>of</strong> the patient’s<br />

peripheral blood smear revealed inclusion bodies (morulae) in<br />

granulcytes; no parasites were seen. Subsequently, serum PCR<br />

for A. phagocytophilum was positive. He required a brief course<br />

<strong>of</strong> hemodialysis and rapidly improved, with normalization <strong>of</strong><br />

laboratory values.<br />

Case series: Fourteen patients presented to our hospital<br />

between May and November. All patients were from suburban<br />

Massachusetts. The mean age was 67 years and the clinical<br />

Elevated liver enzymes 8 (57%)<br />

features are shown in the table below. There were no deaths,<br />

but two thirds <strong>of</strong> the patients required hospital admission and<br />

Inclusion bodies in smear 2 (14%)<br />

two were admitted to the ICU, one with sepsis and severe renal failure (case presentation), and one with<br />

hypotension causing demand ischemia. None <strong>of</strong> our patients had co-infection with Borrelia burgdorferi.<br />

At the onset, morulae were seen in peripheral blood smears <strong>of</strong> both ICU patients. The diagnosis was<br />

established serologically in all <strong>of</strong> the patients, but acute sera for anaplasma were negative in all <strong>of</strong> the<br />

patients.<br />

DISCUSSION: The clinical manifestations <strong>of</strong> anaplasmosis are highly variable. Host factors, including<br />

older age, are the main determinants <strong>of</strong> the severity <strong>of</strong> the infection. Severe infection causing end-organ<br />

dysfunction can occur, particularly in the elderly. The older age <strong>of</strong> our patients suggests that<br />

anaplasmosis is probably underdiagnosed in healthy persons. Clinicians in an endemic area must be<br />

aware <strong>of</strong> this emerging illness in order to initiate prompt treatment. The peripheral smear may lead to a<br />

rapid diagnosis, but if anaplasmosis is suspected, the patient should receive doxycycline and clinicians<br />

should not rely on initial serology.<br />

The Hidden Clot-A case <strong>of</strong> 'Non-Paradoxical' Embolism<br />

Syeda A Batul, MBBS Arben Dashi, MD Padma L. Draksharam, MBBS Anjula Gandhi, MD<br />

INTRODUCTION: Although more commonly recognized in association with transient ischemic attacks<br />

and cryptogenic strokes particularly in relatively younger population, a patent foramen ovale should be<br />

considered in patients with evidence <strong>of</strong> systemic thrombosis who develop paradoxical embolism. The<br />

origin <strong>of</strong> the thrombus maybe within the deep veins <strong>of</strong> lower extremities or pelvis in patients with<br />

predisposing factors however, a clot may form within the redundant portion <strong>of</strong> the atrial septum itself<br />

and there on follow an unpredictable course. Bilateral central pulmonary embolism from a possible<br />

thrombus lodged within the atrial septal aneurysm (ASA) in the presence <strong>of</strong> patent foramen ovale (PFO)<br />

although not unheard <strong>of</strong> still represents an uncommon entity. We report here a case <strong>of</strong> massive central<br />

pulmonary embolism in a patient with previously undiagnosed atrial septal aneurysm and patent<br />

foramen ovale.<br />

CASE PRESENTATION: A 56 year old female with came to the hospital with epigastric burning for a week.<br />

Symptoms were progressive with loss <strong>of</strong> appetite and weakness. Review <strong>of</strong> systems was otherwise<br />

negative. Physical examination was remarkable for some non specific tenderness in the epigastric<br />

region. In the emergency room the patient was hemodynamically stable but found to have<br />

hyperglycemia and anion gap ketoacidosis (anion gap 28; large acetone in blood). After receiving initial<br />

care under intensive care unit the patient was transferred to medical floor for further care. Two days<br />

into her hospital course she had complains <strong>of</strong> dizziness and chest pressure followed by the development<br />

<strong>of</strong> hypoxia, hypotension and tachycardia. electrocardiogram showed the development <strong>of</strong> right heart<br />

strain pattern as to opposed to a normal EKG on admission accompanied with a significant elevation in<br />

D-Dimers (3138). CT angiogram <strong>of</strong> the chest showing bilateral central pulmonary embolism and right<br />

ventricular dilation. Patient was started on full dose anticoagulation while a lower extremity doppler<br />

ruled out venous thrombosis. A transthoracic echocardiogram was also performed showing a<br />

pedunculated highly mobile mass within the left atrium tethered to the inter-atrial septum. The<br />

differential diagnosis at this time included endocarditis, intracardiac thrombus or atrial myxoma. A<br />

transesophageal echocardiogram done the following day however, failed to identify the septal mass but<br />

showed instead a large mobile mass within right pulmonary artery. Additional findings included those <strong>of</strong><br />

an atrial septal aneurysm with patent foramen ovale. The patient was continued on anticoagulation and<br />

discharged once stable with referral for assessment <strong>of</strong> closure PFO.<br />

DISCUSSION: Atrial septal aneurysm previously considered a rare entity has been fairly well recognized<br />

since the advent <strong>of</strong> transesophageal echocardiography. The prevalence in general population is thought<br />

to be around 2-10% with up to 70% <strong>of</strong> the cases having a co-existing patent foramen ovale. Strokes in<br />

younger patients from paradoxical embolism, migraines with aura or systemic emboli are fairly well<br />

reported in literature but there are some case reports highlighting the entrapment or lodging <strong>of</strong><br />

thrombus within the ASA/PFO with subsequent embolization to the pulmonary vasculature.<br />

Transthoracic echocardiography may not be always be diagnostic however, the yield may be increased<br />

with transesophageal echocardiograpy or newer modalities such as 3-dimensional echocardiography,<br />

contrast enhanced dynamic MRI or ECG gated multidimensional CT angiogram where available. A<br />

thromboembolic event with evidence <strong>of</strong> PFO mandates closure. Percutaneous closure techniques are<br />

employed for this purpose with great success and minimal procedural complications.<br />

Severe Hypertonic Hyponatremia following Cardiac Catheterization in a Patient with Normal Kidney<br />

Function<br />

Dhavalkumar Sureja, MD, Robert Grunberg, MD, Ravi Makwana, MD, Mahesh Krishnamurthy, MD FACP<br />

INTRODUCTION: Hyponatremia is common in hospitalized patients, particularly after surgical<br />

procedures and is associated with higher mortality. Impaired kidney function is associated with increase<br />

morbidity and mortality after primary coronary intervention. A correlation between administration <strong>of</strong> IV<br />

contrast and the development <strong>of</strong> hyponatremia is known in patients with advanced renal disease.<br />

However, contrast induced hypertonic hyponatremia in patients with normal renal function is<br />

uncommon and severe hyponatremia is rare. Hyponatremia can develop within hours after the<br />

procedure and resolves rapidly thereafter. We report a case <strong>of</strong> contrast induced severe hyponatremia in<br />

a patient with normal renal function.<br />

CASE PRESENTATION: This is a 52-year-old male with no significant past medical history presented<br />

with chest discomfort and shortness <strong>of</strong> breath. His stress test was abnormal, and he underwent cardiac<br />

catheterization which showed multi-vessel coronary artery disease requiring stenting. In the morning<br />

before the procedure, the patient had blood urea nitrogen (BUN) 17 mg/dl, creatinine 0.9 mg/dl, serum<br />

sodium 140 mEq/L, potassium 4.2 mEq/L, chloride 105 mEq/L and bicarbonate 28 mEq/L. During the<br />

procedure, he developed pulmonary edema and required intubation. Thereafter, he experienced<br />

recurrent episodes <strong>of</strong> ventricular tachycardia/fibrillation which led to multiple cardio-versions. After a<br />

very complicated and prolonged procedure where >200 ml <strong>of</strong> contrast was used, an intra-aortic balloon<br />

pump was inserted due to hypotension. The balloon pump was removed within seven hours post<br />

catheterization and subsequent labs later that day revealed a serum sodium 115 mEq/L, potassium 6.6<br />

mEq/L, chloride 86 mEq/L, bicarbonate 20 mEq/L, BUN 16 mg/dl, creatinine 1.3 mg/dl, and serum<br />

Otto Ostolaza, MD (Associate), Carlos Rosado, MD, Hector R. Cordova, MD, FACP<br />

INTRODUCTION: The use <strong>of</strong> herbal medicines and dietary supplements to promote health and treat<br />

various chronic diseases has increased globally. The majority <strong>of</strong> these supplements have not been tested<br />

for efficacy and safety. Their chemical composition is not always well-established, and the dosage and<br />

route <strong>of</strong> administration are not standardized. The problems and concerns <strong>of</strong> herbal supplements arise<br />

from intrinsic toxicity, adulteration, contamination, substitution, misidentification, mistaken labeling, or<br />

poor quality control. Co-administration <strong>of</strong> herbal medicines with conventional drugs raises the potential<br />

<strong>of</strong> herb-drug interactions, which may cause altered drug elimination or toxicity.<br />

CASE PRESENTATION: A 55 y/o man with medical history <strong>of</strong> Chronic Kidney Disease Stage IV<br />

secondary to Type 2 Diabetes Mellitus, HCV s/p liver transplant (2000) with recurrence on chronic<br />

immunosuppression, coronary artery disease, arterial hypertension, and dyslipidemia developed<br />

weakness while at the grocery store. Once at home, he was hypotensive (85/53mmHg) and bradycardic<br />

(44bpm). His chronic medications included mycophenolate, cyclosporine, captopril, isosorbide,<br />

metoprolol, and nifedipine. A week before this event, he had started a natural supplement called<br />

Transfer Factor KBU (Kidney, Bladder, and Urinary Tract). At the ER he was found with hyperkalemia <strong>of</strong><br />

9.6mEq/L with associated peak T waves, bradycardia (48bpm), and a first degree AV block in EKG.<br />

Medical therapy for hyperkalemia including insulin IV, dextrose, Kayexalate, and calcium gluconate was<br />

administered with consequent resolution <strong>of</strong> ECG changes and decreasing trend <strong>of</strong> serum potassium. The<br />

patient was discharged home with instructions to discontinue the Transfer Factor KBU. On follow up<br />

appointments, no recurrence <strong>of</strong> hyperkalemia was identified.<br />

DISCUSSION: Within the active ingredients <strong>of</strong> KBU is Dandelion leaf (Taraxacum <strong>of</strong>ficinale), a herbal<br />

supplement that has been used as a diuretic and has a high potassium content, which increases the risk<br />

<strong>of</strong> hyperkalemia. Also it has been shown to inhibit cytochrome P450, that in patients using cyclosporine,<br />

increases drug bioavailability and the risk <strong>of</strong> cyclosporine-induced hyperkalemia, which is brought about<br />

by suppression <strong>of</strong> plasma renin activity and induction <strong>of</strong> renal tubular insensitivity to aldosterone,<br />

resulting in impairment <strong>of</strong> potassium excretion. To our knowledge, there are no case reports about<br />

Transfer Factor KBU-induced hyperkalemia in the targeted literature. <strong>Physicians</strong> need to caution their<br />

patients about the use <strong>of</strong> herbal preparations and educate them about the risks and potentially fatal<br />

consequences <strong>of</strong> their use.<br />

(Member), William Beaumont Army Medical Center, El Paso, TX<br />

INTRODUCTION: Aldosterone producing adrenocortical carcinoma (APAC) is a very rare malignancy. It<br />

usually presents in a clandestine manner with hypertension, potassium wasting or as an incidentaloma.<br />

We present a case <strong>of</strong> a 62-year-old male who presented atypically with metastatic APAC.<br />

CASE PRESENTATION: Our patient presented in June 2011 for chest pain. During admission he was<br />

found to have mild hypertension, severe potassium wasting and metabolic alkalosis. His potassium was<br />

1.7 on admission and required excessive amounts <strong>of</strong> IV and oral potassium replacement. He was a poor<br />

historian, however eventually revealed a long history <strong>of</strong> adrenal disease to include partial left<br />

adrenalectomy in 2004 for a "Pheochromocytoma". During his admission Pheochromocytoma was ruled<br />

out and Conn's syndrome with severe potassium wasting was diagnosed. Adrenal CT imaging revealed a<br />

2.2 x 2.4 x 2.4cm hyperdense nodule <strong>of</strong> his left adrenal gland and multiple other non-calcified and<br />

calcified nodules near the adrenal mass, in the retroperitoneal space and involving his omentum.<br />

Exploratory laparotomy with excisional biopsy <strong>of</strong> the omental mass and several diaphragmatic nodules<br />

was performed. Omental mass histology revealed 6 mitotic figures per HPF and a paucity <strong>of</strong> vacuolated<br />

cells. Immunohistochemical stains had strong positivity for Calretinin, Vimentin and MART-1/melan A.<br />

Inhibin and Synaptophysin were focally blush positive. Pancytokeratin and Chromogranin were negative.<br />

Ki-67 proliferative index approached 15-20%. Modified Weiss criteria was >3, consistent with ACC.<br />

Clinical, biochemical, and histologic findings support APAC diagnosis; however, diagnostic considerations<br />

include an implant from an adrenocortical adenoma secondary to prior adrenalectomy, ectopic<br />

adrenocortical adenoma, extension from adjacent neoplasm, a metastatic process or other entities.<br />

DISCUSSION: Discovery <strong>of</strong> adrenal incidentalomas is increasing as imaging technologies advance.<br />

Adrenal incidentalomas may be benign or malignant adrenal tumors, metastatic tumors, infection,<br />

adrenal hemorrhage or adrenal hyperplasia. Roughly fifty percent <strong>of</strong> incidentalomas are benign<br />

adenomas.<br />

Adrenocortical Carcinoma (ACC) is a rare aggressive disease with an estimated incidence <strong>of</strong> one case per<br />

two million people annually with a female preponderance <strong>of</strong> 2.5:1. ACC’s can present as non-functioning<br />

tumors or hyperfunctioning tumors. Cushing’s syndrome with virilization is the most common<br />

presentation <strong>of</strong> hyperfunctioning ACC. APAC account for 6% and Estrogen-producing tumors account for<br />

2% <strong>of</strong> hyperfunctioning tumors, respectively.<br />

Ten percent <strong>of</strong> APAC are metastatic at diagnosis and 50% are metastatic by follow up. It is essential to<br />

diagnose and resect this tumor early and to implement continuous surveillance since this malignancy<br />

has a high rate <strong>of</strong> recurrence and death.<br />

Acyclovir Induced Rhabdomyolysis<br />

Vince Faridani, MD, Adil Akthar M.D, Nugma Chadha M.D., Jim Mertz M.D.<br />

INTRODUCTION: Acyclovir is an acyclic guanosine analogue used in the treatment <strong>of</strong> herpes simplex<br />

virus and varicella-zoster virus. Although generally well tolerated, usage <strong>of</strong> acyclovir may be complicated<br />

by development <strong>of</strong> acute renal failure in select patients. The following case demonstrates a rare case <strong>of</strong><br />

rhabdomyolysis induced acute tubular necrosis in a patient with on antiretroviral therapy.<br />

CASE PRESENTATION: A 29 year old female with a known history <strong>of</strong> type I diabetes and end stage<br />

renal disease on peritoneal dialysis presented to the hospital with altered mental status, weakness, and<br />

vomiting. Four days prior she was started on oral acyclovir therapy for treatment <strong>of</strong> genital herpes.<br />

Upon initial presentation, afebrile, vital signs stable. Physical examination revealed the patient to be<br />

confused and not orientated x 0, no focal neurological deficits. Initial evaluation, CT head was negative<br />

for acute injury and lumbar puncture revealed CSF to be normal. Laboratory studies, Na 122, K 3.7, BUN<br />

87, Creatinine 12.3, and Phosphorus 11.2, creatine kinase (CK) 20,199. Serological work including ASO<br />

titers was negative. HIV viral load was undetectable. The patient was immediately discontinued from her<br />

acyclovir, given IV fluids, underwent emergent hemodialysis for two consecutive days given her acute on<br />

chronic renal failure, altered mental status, and elevated CK. Nearly 48 hours later her CK decreased and<br />

mentation returned to baseline. Hemodialysis was discontinued and she resumed her peritoneal<br />

dialysis.<br />

DISCUSSION: The mechanism <strong>of</strong> acyclovir-induced acute tubular necrosis classically involves the<br />

administration <strong>of</strong> intravenous acyclovir leading to precipitation <strong>of</strong> crystals within the nephron tubules<br />

and renal parenchyma. However the above case highlights a different physiologic mechanism whereby<br />

oral acyclovir can lead to reversible rhabdomyolysis-induced uremic encephalopathy and oliguric acute<br />

kidney injury. Clinicians should also be aware that acyclovir-related renal failure can occur with lower<br />

doses <strong>of</strong> oral therapy as well as rapid IV infusions. This consideration is especially important when<br />

dealing with patients who have underlying chronic kidney disease. These patients warrant lower doses<br />

<strong>of</strong> acyclovir treatment given their greater predisposition to renal damage.<br />

Pheochromocytoma: A Cause <strong>of</strong> Stemi, Transient Left Venticular Dysfunction and Takotsubo<br />

Cardiomyopathy<br />

Sheela Subramanyam, MD(first) Robert Kreisberg, MD(second)<br />

INTRODUCTION: Takotsubo Cardiomyopthy(TC) has been believed to occur due to elevated<br />

catecholamines that can occur for a variety <strong>of</strong> reasons. A functioning adrenal gland tumor such as a<br />

pheochromocytoma can cause significant elevations in catecholamines resulting in TC. We present a<br />

unique case <strong>of</strong> a pheochromocytoma causing elevations <strong>of</strong> catecholamines resulting in an acute<br />

coronary syndrome as well as TC.<br />

CASE PRESENTATION: A 60 year old man with previous history <strong>of</strong> angioplasty with stent placement<br />

and a pacemaker for sick sinus syndrome was hospitalized with complaints <strong>of</strong> chest pain radiating to the<br />

left shoulder, jaw and occasionally to the back. He also complained <strong>of</strong> palpitations, infrequent<br />

headaches,episodes <strong>of</strong> diaphoresis and labile hypertension ranging from 200/110mm <strong>of</strong> Hg to 60/40<br />

mm <strong>of</strong> Hg for the past month. Three months previously he had presented with pericarditis and<br />

pericardial effusion for which a pericardial window was performed. His past history reveals atrial<br />

fibrillation, dyslipidemia, hypertension, diabetes, nephrolithiasis and gout. During a recent<br />

hospitalization, he was found to have a 2.1 cm adrenal mass on computed tomography <strong>of</strong> abdomen. He<br />

had undergone numerous cardiac procedures for paroxysmal chest pain and a stress test done three<br />

months ago did not reveal ischemia.<br />

On the day <strong>of</strong> admission, the patient was afebrile and his blood pressure was 116/69 mm <strong>of</strong> Hg. His<br />

electrocardiogram showed ST segment elevation in II, III, aVf, V2 –V4 consistent with anterior and<br />

inferior wall myocardial infarction. These results were also supported by the raised cardiac markers<br />

including troponins-1.944 ng/ml and 1.447ng/ml respectively at entry and six hours later. His continued<br />

home medications were continued and he was started on amlodipine for atrial fibrillation. Two days<br />

later, he underwent cardiac catheterization which showed severe hypokinesis <strong>of</strong> the anterior, apical and<br />

common inferior wall segment possibly consistent with TC but no obstructive coronary atherosclerosis.<br />

In view <strong>of</strong> his symptoms and the adrenal mass, he was started on labetolol. Amiodarone was<br />

discontinued because <strong>of</strong> QTc prolongation and he was discharged to be followed on outpatient basis.<br />

The patient again developed similar symptoms and was readmitted to the hospital. All his lab findings<br />

were normal including cardiac markers except for 24 hour urine total metanephrines(2204 nmol/L),<br />

normetanephrines (994nmol/L) and VMA (7.9mg/24 hrs). A left ventriculogram revealed TC with apical<br />

ballooning <strong>of</strong> left ventricle and an EF <strong>of</strong> 20% to 25% . The patient was suspected to have a<br />

pheochromocytoma based on the clinical findings, lab reports and history <strong>of</strong> adrenal incidentaloma.<br />

Inspite <strong>of</strong> severe cardiac risk, a decision to perform right adrenalectomy was made and he was started<br />

on phenoxybenzamine for two weeks before the surgery.<br />

The pathological report confirmed the tumor to be a pheochromocytoma. After resection, his condition<br />

drastically improved and a repeat ventriculogram showed an improvement in ejection fraction and<br />

reversal <strong>of</strong> wall motion abnormalities.<br />

174


DISCUSSION: Pheochromocytomas are rare neuroendocrine tumors responsible for 0.3% <strong>of</strong> the cases<br />

<strong>of</strong> secondary hypertension that are investigated and more than 4% <strong>of</strong> the incidental adrenal masses<br />

found by imaging for non-adrenal complaints.Typical symptoms including the triad <strong>of</strong> headache, labile<br />

hypertension and diaphoresis raise the suspicion <strong>of</strong> pheochromocytoma but their absence can present a<br />

great challenge in diagnosis. This tumor can be deceptive and presentations can vary from back pain to<br />

severe cardiac manifestations and acute renal failure. The manifestations <strong>of</strong> these tumors differ<br />

because <strong>of</strong> the different effects <strong>of</strong> the catecholamines and the relative proportions <strong>of</strong> the type <strong>of</strong><br />

catecholamine produced. Tumors which produce only norepinephrine generally present with<br />

uncontrolled hypertension, however the tumors which produce both epinephrine and nor-epinephrine<br />

manifest with episodic hypertension. Catecholamine secretion in pheochromocytomas is not regulated<br />

in the same manner as in healthy adrenal tissue. Pheochromocytomas are not innervated, and<br />

catecholamine release is not precipitated by neural stimulation. The trigger for catecholamine release is<br />

unclear, but multiple mechanisms have been postulated, including direct pressure, medications, and<br />

changes in tumor blood flow .<br />

The unusual presentations include rare cardiac manifestations such as an acute coronary syndrome,<br />

rhythm disturbances such as ventricular tachycardia, ST elevation, QTc prolongation and T wave<br />

changes, reversible cardiomyopathy, systolic heart failure and cardiogenic shock. It has been noted that<br />

right sided pheochromocytomas are more likely to be associated with clinical symptoms and<br />

electrocardiographic abnormalities. In the case reported above, the patient had symptoms <strong>of</strong> acute<br />

coronary syndrome with ECG changes and also TC.<br />

Proposed mechanisms for TC include epicardial spasm, microvascular dysfunction, hyperdynamic<br />

contractility with midventricular or outflow tract obstruction and direct effects <strong>of</strong> catecholamines on<br />

cardiomyocytes.<br />

The effects <strong>of</strong> norepinephrine (NE) and epinephrine (E) on ventricular myocytes have been extensively<br />

studied. NE acts on the ß1 and E on the ß2 adrenergic receptors; the latter are abundant in the human<br />

ventricular myocardium. In transgenic mice, physiological levels <strong>of</strong> NE and E act on their respective<br />

receptors and activate Gs protein, creating a positive inotropic effect and increased contractility.<br />

However at supra-physiological levels <strong>of</strong> E, a negative inotropic response occurs, resulting from a switch<br />

in signaling from Gs to Gi; a phenomenon called “stimulus trafficking.” “Stimulus trafficking” has been<br />

proposed as a mechanism which prevents excess catecholamine-mediated damage to the myocytes.<br />

After the restoration <strong>of</strong> physiologic catecholamine levels, ß2 receptors reverse to Gs stimulation allowing<br />

myocyte recovery. ß2 receptors occur in greater abundance at the apex relative to the base <strong>of</strong> the heart<br />

which may explain why E affects the apical region <strong>of</strong> the heart in stress cardiomyopathy.<br />

A Catastrophic Diagnosis: Case Report <strong>of</strong> Asherson’s Syndrome<br />

Phillip Henderson, DO University <strong>of</strong> South Alabama Department <strong>of</strong> Internal Medicine<br />

INTRODUCTION: Catastrophic Antiphospholipid Antibody Syndrome (CAPS) or Asherson’s Syndrome is<br />

a rare syndrome characterized by rapidly progressive multi-organ system failure, multiple small vessel<br />

thrombosis and positive antiphospholipid antibodies. This syndrome is predominately found in women<br />

with known systemic lupus or primary antiphospholipid syndrome; however, can be found in patients<br />

with no prior history <strong>of</strong> rheumatologic disease. CAPS should be considered in rapidly declining patients<br />

presenting with microangiopathies with or without a previous history <strong>of</strong> rheumatologic disease.<br />

CASE PRESENTATION: A 60-year-old Vietnamese female presented with shortness <strong>of</strong> breath, fatigue,<br />

and arthralgias. Physical exam revealed muffled heart sounds and decreased breath sounds at the lung<br />

bases. Echocardiogram revealed a pericardial effusion with impending tamponade. Emergent drainage<br />

was performed. After drainage she developed respiratory distress requiring ICU monitoring overnight.<br />

She initially improved but then declined. She rapidly developed multi-organ system failure including<br />

coagulopathy, renal failure, obtundation, acute liver injury, and hemodynamic collapse with associated<br />

digital ischemia. Cultures did not reveal a source <strong>of</strong> infection. The evaluation <strong>of</strong> her coagulopathy<br />

showed an increased PT, PTT and fibrin split products, but normal fibrinogen. The patient’s platelets<br />

were persistently below 20,000/mcl. The peripheral smear showed decreased platelet numbers but no<br />

schistocytes; however, ANA was found high positive. Further autoimmune workup revealed a positive<br />

anti-smith, high dsDNA titers, and undetectable complement levels. When signs <strong>of</strong> digital thrombosis<br />

developed lupus anticoagulant was performed which showed presence <strong>of</strong> a lupus-type inhibitor. Given<br />

the appearance <strong>of</strong> a rapid thrombotic coagulopathy coupled with a positive lupus anticoagulant, the<br />

diagnosis <strong>of</strong> probable catastrophic antiphospholipid antibody syndrome (CAPS) was made. High dose<br />

pulse corticosteroids were initiated as well as plasmapharesis. Her organ dysfunction resolved after<br />

treatment was initiated. Despite aggressive care the patient’s platelet count remained persistently low,<br />

so rituximab was implemented and platelet dysfunction resolved. One week after treatment, she<br />

developed an intraparenchymal hemorrhage and expired several days later.<br />

DISCUSSION: This case demonstrates a life-threatening complication <strong>of</strong> systemic lupus. There have<br />

been approximately 300 reported cases <strong>of</strong> CAPS. The diagnosis <strong>of</strong> CAPS is challenging due to the great<br />

overlap with the other thrombotic microangiopathies. To make the diagnosis <strong>of</strong> CAPS preliminary<br />

criteria are in place which include evidence <strong>of</strong> three organ system dysfunction with rapid onset <strong>of</strong><br />

dysfunction within one week, tissue evidence <strong>of</strong> small vessel occlusion, and positive antiphospholipid<br />

antibodies. Treatment should be initiated if high index <strong>of</strong> suspicion due to the high risk <strong>of</strong> mortality <strong>of</strong><br />

around 50%. Anticoagulation, corticosteroids and plasmapharesis are the cornerstone <strong>of</strong> initial therapy<br />

to reverse the multi-organ insult <strong>of</strong> CAPS. For refractory cases <strong>of</strong> immune related anemia and<br />

thrombocytopenia rituximab has been shown to be effective.<br />

Croaking on Crocus<br />

Nick Sparacino, DO Lise Harper, MD<br />

INTRODUCTION: Colchicine is an ancient drug extracted from plants <strong>of</strong> the lily family and is used<br />

primarily for its anti-inflammatory properties in gouty arthritis. It has a narrow therapeutic index and<br />

can therefore result in serious toxicity and death if used inappropriately.<br />

CASE PRESENTATION: A 74-year old female with a history <strong>of</strong> osteoarthritis and chronic pain was<br />

admitted to the general medicine ward with symptoms <strong>of</strong> nausea, vomiting, diarrhea and<br />

dehydration. Initial work-up found her to have acute myocarditis, pancytopenia, acute renal failure and<br />

elevation <strong>of</strong> her hepatic function tests. Her non-specific constellation <strong>of</strong> symptoms presented a<br />

diagnostic dilemmna further confounded by her recent extended visit to Iran. A thorough history<br />

revealed chronic administration <strong>of</strong> high-dose IV colchicine (a drug no longer available for use in the<br />

United States) for treatment <strong>of</strong> her chronic joint pain by a local naturopathic physician.<br />

The patient was resuscitated and treated with supportive measures, with ultimate resolution <strong>of</strong><br />

symptoms and labratory abnormalities. Though she subsequently developed peripheral neuropathy as<br />

well as the characteristic alopecia, she was fortunate to improve considerably and was discharged to<br />

home.<br />

DISCUSSION: Colchicine containing plants were first recognized as having both therapeutic and toxic<br />

properties by Egyptians as early as 1500 BCE. The therapeutic use <strong>of</strong> colchicine proper dates to the early<br />

19th century, and is prescribed primarily for its anti-inflammatory effects in gout and other<br />

inflammatory conditions. It acts by binding intracellular tubulin, which in turn inhibits microtubule<br />

polymerization and spindle formation and ultimately hinders cellular mitosis. As microtubules are<br />

ubiquitous in human cells, disruption <strong>of</strong> their function can have widespread detrimental<br />

effects. Toxicities primarily manifest initially as gastrointestinal symptoms with supsequent dehydration<br />

and hypovolemia. Many other organ systems can be affecteed, including cardiovascular, respiratory,<br />

neurologic, hematologic, renal, musculoskeletal, and integumentary. Its narrow therapeutic index<br />

allows for these serious adverse effects to arise rapidly. Though colchicine has both oral and IV<br />

formulations, the FDA has taken the IV form <strong>of</strong>f the market given the severity <strong>of</strong> its toxic effects. This<br />

case was notable for both the diagnostic challenge as well as the ethical dilemmna involved.<br />

Difficult Situation: Bleeding in a Patient with an Acquired Factor VIII Inhibitor.<br />

Peter Cherian, MD, Nalini Tirumalasetty, MD Alison Stopeck, MD<br />

CASE PRESENTATION: 79-year-old male with a history <strong>of</strong> atrial fibrillation and deep venous thrombosis<br />

developed osteomyelitis and staphylococcus sepsis secondary to trauma sustained in a MVA. He was<br />

discharged on IV nafcillin and coumadin. He was readmitted 2 weeks later for significant bleeding from<br />

his left lower extremity. His hemoglobin had decreased from 10.9 g/dl to 7 g/dl. Coumadin was<br />

discontinued and he was treated with fresh frozen plasma and multiple blood transfusions. Despite<br />

therapy, he continued to bleed. Lab studies revealed an elevated PTT which did not correct on mixing<br />

with normal plasma (mixing study). Factor VIII levels were 172 BU. He was diagnosed with an acquired factor VIII inhibitor and treated with low dose<br />

rVIIa for his bleeding. He was also started on oral prednisone and cyclophosphamide as therapy for his<br />

inhibitor. The patient's left lower extremity continued to bleed requiring daily transfusions with PRBC<br />

despite rVIIa therapy and thus he received a single dose <strong>of</strong> FEIBA (Anti-Inhibitor Coagulant Complex<br />

concentrate). Within 2 hrs <strong>of</strong> FEIBA infusion, he developed an inferior ST-elevation myocardial<br />

infarction. His condition continued to deteriorate and he expired on hospital day 16.<br />

DISCUSSION: Hemophilia A can be congenital or acquired. This case demonstrates acquired Hemophilia<br />

A caused by an autoantibody directed against FVIII. This is a rare bleeding diathesis with an incidence <strong>of</strong><br />

1 to 4 per million population. Although uncommon, it is associated with a 90% risk <strong>of</strong> bleeding and a<br />

mortality between 8-22%. Unlike congenital factor deficiency in which hemarthroses are the usual site<br />

<strong>of</strong> bleeding, in acquired FVIII deficiency s<strong>of</strong>t tissue and mucosal bleeding are more common. There is a<br />

biphasic age distribution with a small peak between 20 and 30 years and a major peak between 68 and<br />

80 years. Acquired FVIII inhibitors have been associated with autoimmune disorders, postpartum, solid<br />

cancers, hematological malignancies, acute hepatitis B and C and as in this case exposure to<br />

penicillin. The diagnosis is based on an isolated prolongation <strong>of</strong> the PTT which is not corrected by<br />

incubating the patient’s plasma with an equal volume <strong>of</strong> normal plasma (mixing study). Decreased levels<br />

<strong>of</strong> FVIII and a positive Bethesda assay (FVIII inhibitor assay) confirm the diagnosis. Treatment is aimed at<br />

controlling the acute bleeding with bypass agents and ultimately eradicating the FVIII inhibitor. Treating<br />

the acute bleed can be accomplished either by raising the circulating factor VIII levels sufficiently with<br />

infusion <strong>of</strong> FVIII concentrate or by using bypassing agents such as recombinant activated factor VII or<br />

activated prothrombin complex concentrate. Inhibitor eradication can be achieved by the use <strong>of</strong><br />

immunouppressive agents. This case demonstrates the importance <strong>of</strong> recognizing this disorder as well<br />

as the difficulty in treating it.<br />

INTRODUCTION: Systemic mastocyctosis is a rare disorder and diagnostic challenge in the absence<br />

<strong>of</strong> cutaneous manifestations.<br />

CASE PRESENTATION: A 69 year-old Caucasian male with coronary artery disease presented with a<br />

syncopal episode in the setting <strong>of</strong> one month <strong>of</strong> diarrhea. The patient endorsed chest pain and was<br />

hypotensive with a systolic blood pressure <strong>of</strong> 56 mmHg. Physical exam was otherwise unremarkable.<br />

Initial labs showed leukocytosis with mild neutrophilia, anemia (hgb 12.2 g/dl), elevated cardiac<br />

enzymes, and acute kidney injury.Despite antibiotics, intravenous fluids, and vasopressors, the patient<br />

remained hypotensive. Echocardiography demonstrated a LVEF <strong>of</strong> 45% and multiple wall motion<br />

abnormalities. Emergent coronary angiography revealed no new occlusive lesions and diminished<br />

collateral flow compared to prior angiogram. These findings, in addition to right heart catheterization<br />

hemodynamic measurements, suggested cardiogenic shock due to demand ischemia, possibly secondary<br />

to hypotension. Infectious disease work up was negative. The patient deteriorated, developing shock<br />

liver, renal failure, and worsening cardiomyopathy.A tryptase level, obtained to assess for anaphylaxis,<br />

was elevated at 56 ng/dL (normal

INTRODUCTION: Primary effusion lymphoma (PEL) is a rare variant <strong>of</strong> diffuse large B cell lymphoma,<br />

found mostly in immunodeficient individuals, largely marked by pleural, pericardial and even peritoneal<br />

effusions and rarely presents as an extracavitary lesion. The presentation <strong>of</strong> PEL in Kaposi’s sarcoma<br />

patients can be missed in the differential amidst the setting <strong>of</strong> complicated HIV disease delaying<br />

promising therapy.<br />

CASE PRESENTATION: A 29 year old male with a past medical history significant for hypothyroidism<br />

and asthma presented in April 2011 with worsening shortness <strong>of</strong> breath while on exertion and at rest.<br />

On exam, he was noted to have rales and dullness to percussion at the left lung base as well as<br />

hyperpigmented skin lesions concerning for Kaposi’s sarcoma. The initial differential was broad including<br />

community acquired pneumonia, influenza, pneumocystis pneumonia, and fungal infection. Lab results<br />

revealed the patient was HIV positive. Chest radiograph was notable for a left sided pleural effusion.<br />

Diagnostic thoracentesis was performed and routine examination, including cytopathology and flow<br />

cytometry, was non-diagnostic. The patient was treated supportively and discharged with plan for<br />

HAART. He returned in May 2011 with continued worsening shortness <strong>of</strong> breath. Bronchoscopy revealed<br />

possible disseminated KS. Per Oncology, he underwent three cycles <strong>of</strong> Doxil with the addition <strong>of</strong><br />

Vincristine on the third cycle for treatment <strong>of</strong> disseminated KS. His pleural effusion did not resolve.<br />

During cycle three in July 2011, he developed a left neck mass in the supraclavicular region. FNA biopsy<br />

<strong>of</strong> mass was significant for large atypical lymphoid cells. Immunostains <strong>of</strong> core biopsy were CD 138+,<br />

HHV8+, MUM-1+, EBV-EBER+, and ki-67 (95%) consistent with a diagnosis <strong>of</strong> extracavitary PEL. Bone<br />

marrow biopsy for staging did not demonstrate features <strong>of</strong> infiltration. Patient was started on dose<br />

adjusted Etoposide, Prednisone, Vincristine, Cyclophosphamide, Doxorubicin (EPOCH) and continues<br />

therapy with symptomatic improvement and stable effusions.<br />

DISCUSSION: It is important to remember the HHV8 association between PEL and Kaposi’s sarcoma<br />

since Kaposi’s sarcoma patients are known carriers <strong>of</strong> HHV8/KSHV DNA. Cells in the malignant pleural<br />

effusions <strong>of</strong> PEL are infected with the HHV8 virus. The malignant lymphocytes in PEL have a<br />

characteristic immunophenotype, however the routine flow cytometric panel used by commercial<br />

laboratories will miss this diagnosis. Thus, the possibility <strong>of</strong> PEL in newly diagnosed HIV and Kaposi’s<br />

sarcoma patients should be strongly considered and clinically assessed especially in the setting <strong>of</strong><br />

patients presenting with new onset shortness <strong>of</strong> breath, pleural effusions <strong>of</strong> unknown etiology, or nodal<br />

lesions. PEL, while rare, has variable manifestations and is known to have rapid clinical progression with<br />

a median survival <strong>of</strong> 6 months. However, therapies such as EPOCH after initiation <strong>of</strong> a HAART regimen<br />

can improve patient’s quality <strong>of</strong> life and even sometimes lead to remission.<br />

Anemia, Hypercalcemia, Renal Failure with Multiple Lytic Bone Lesions: It is not Multiple Myeloma<br />

Jaimeet S. Chhabra, DO MPH, Minho Yu, DO<br />

INTRODUCTION: Langerhans cell histiocytosis (LCH) is a rare proliferative disorder <strong>of</strong> histiocyte<br />

cells. Because <strong>of</strong> its rarity and clinician’s lack <strong>of</strong> awareness, the diagnosis <strong>of</strong> LCH is <strong>of</strong>ten delayed or<br />

missed. Here we present a case <strong>of</strong> patient who presented to emergency room with unrelated<br />

complaints, incidentally found to have hypercalcemia, anemia, renal failure with lytic bone lesions<br />

whom after multiple bone marrow biopsies was diagnosed with LCH.<br />

CASE PRESENTATION: 51 year old Caucasian man presented to the emergency room with blurry vision<br />

and worsening back and hip pain for four months. The patient had significant past medical history <strong>of</strong><br />

diabetes and systolic heart failure. Incidental findings <strong>of</strong> hypercalcemia, acute renal failure and anemia<br />

prompted an admission to internal medicine service for further workup.<br />

There were no significant findings on cardiovascular, respiratory, gastrointestinal, and skin<br />

exams. Dilated eye exam showed bilateral proliferative diabetic retinopathy. Vertebrates and hips were<br />

tender to palpation.<br />

Laboratory exam showed normocytic anemia (10.2 g/dl) with thrombocytopenia (130 x<br />

Posaconazole Versus Paecilomyces: To Boldly Go Where No Triazole Has Gone Before<br />

Stacy H Shoshan, MD, Peter Le, MD, Sally Slome, MD, Aubrey Ingraham, MD<br />

INTRODUCTION: Paecilomyces is a filamentous fungus that infects immunocompromised patients<br />

resulting in high mortality rates. We are presenting a case <strong>of</strong> pulmonary Paecilomyces variotti<br />

successfully treated with posaconazole after failing treatment with three conventional antifungals.<br />

CASE PRESENTATION: A 48 year old woman with a past medical history significant for AML treated<br />

with chemotherapy and bone marrow transplant 3 years prior, presented with 2 weeks <strong>of</strong> fever, night<br />

sweats and shortness <strong>of</strong> breath. She was taking prednisone, sirolimus, tacrolimus and acyclovir, as she<br />

had stopped her prophylactic bactrim and voriconazole 6 weeks prior. Interestingly, in the past few<br />

weeks she had cleaned out her attic, went to a dusty outdoor festival and visited an area endemic with<br />

Coccidiomycoses.<br />

In the ED, she was febrile, tachycardic, hypotensive and hypoxic. She had bilateral wheezing, mild<br />

leukocytosis without a left shift, and on chest x-ray she had prominent bibasilar and perihepatic<br />

opacities. On admission, she was started on bactrim, meropenem, azithromycin and fluconazole. The<br />

next day, she underwent bronchoscopy which was grossly normal.<br />

Her hospital course was characterized by worsening hypoxia and altered mental status for which she<br />

was intubated, and switched from fluconazole to voriconazole to amphotericin B. On hospital day 23,<br />

the sensitivities were discerned for this patient Paecilomyces, and since posaconazole had the lowest<br />

MIC, it was added on to her medication regimen. Four days later, the patient was extubated. 3 1/2<br />

weeks later, on hospital day 53, the patient was ambulating without oxygen and discharged to SNF with<br />

the plan to continue posaconazole indefinitely as her prophylactic antibiotic. The patient is currently<br />

one year since discharge, working and doing well.<br />

DISCUSSION: Paecilomyces is a fungus found in air, food and soil worldwide. Voriconazole and<br />

amphotericin B are the conventional treatments for Paecilomyces infections, however despite low in<br />

vitro MICs, they are <strong>of</strong>ten ineffective in vivo resulting in significant morbidity and mortality. Liposomal<br />

amphotericin B consists <strong>of</strong> a phospholipid bilayer intercalated with amphotericin B, the active<br />

ingredient. Amphotericin binds to ergosterol in the fungal cell membrane and creates a transmembrane<br />

channel resulting in ion leakage and ultimately cell death.<br />

Posaconazole, on the other hand, prevents ergosterol synthesis thereby inhibiting fungal cell growth.<br />

There is some evidence that in vitro posaconazole and amphotericin B can be synergistic. In conclusion,<br />

this case report goes beyond the in vitro studies to show that in an immunocompromised patient, the<br />

innovative combination <strong>of</strong> posaconazole and amphotericin B can be used to successfully treat<br />

Paecilomyces variotti pneumonia.<br />

INTRODUCTION: Good syndrome is a rare condition defined as an immunodeficiency in the setting <strong>of</strong> a<br />

history <strong>of</strong> a thymoma with low to absent B cells and hypogammaglobulinemia. Patients usually present<br />

between the fourth and fifth decade <strong>of</strong> life and <strong>of</strong>ten with recurrent sino-pulmonary disease, chronic<br />

non-infective diarrhea and opportunistic infections. Our patient was unique in that in addition to his<br />

recurrent pneumonias he presented with a cavitary lung lesion. Good’s syndrome is not typically<br />

associated with Mycobacterium, and only three such cases have been reported. Additionally, our<br />

patient’s cavitary lesion was negative for Mycobacterium, making this an unusual presentation <strong>of</strong> a rare<br />

syndrome.<br />

CASE PRESENTATION: A 56-year old Ethiopian man with a past medical history relevant for Type A<br />

thymoma resected in 2008 presented with fever, chills, cough, weight loss, and night sweats that<br />

persisted since his resection. He was referred for suspicion <strong>of</strong> tuberculosis to the UCLA Medical Center<br />

after a chest CT showed a 3.5 cm right hilar region mass.<br />

The patient had a low grade fever, good oxygen saturation on room air and otherwise stable vital signs.<br />

A CBC showed evidence <strong>of</strong> relative lymphopenia <strong>of</strong> 1,000. A repeat chest CT revealed an irregular,<br />

cavitating, s<strong>of</strong>t tissue right hilar mass.<br />

Blood and urine cultures including viral serologies and HIV, which along with CMV, AFB,<br />

Coccidiomycosis, Histoplasma, and Aspergillosis were negative. The patient’s induced sputum was found<br />

to be positive for Pneumocystis jiroveci. Given the history <strong>of</strong> the recurrent pneumonia’s, relative<br />

lymphopenia and an opportunistic infection in an HIV negative person a complete immunologic work-up<br />

was done.<br />

The patient’s cell counts were as follows: CD3 absolute count 540 /cmm, CD 4 absolute count 274 /cmm,<br />

CD8 absolute count 280/cmm, CD19 B-Cell absolute count 1 /cmm, IGA 20 mg/dl, IGG 176 mg/dl<br />

Allopurinol Hypersensitivity Syndrome<br />

Maria E Andrae-Hammond, MD<br />

INTRODUCTION: Allopurinol Hypersensitivity Syndrome is a serious complication <strong>of</strong> allopurinol<br />

treatment <strong>of</strong> gout. Diagnostic criteria include a maculopapular rash which can progress to Stevens-<br />

Johnson Syndrome and Toxic Epidermal Necrolysis, internal organ injury, fever, and hematologic<br />

abnormalities. AHS has an incidence <strong>of</strong> one to four per thousand patients and a 25% mortality<br />

rate. Common causes <strong>of</strong> death include sepsis, GI bleeds and hepatic failure. Prevention <strong>of</strong> AHS remains<br />

a major concern among physicians, who are facing an increasing incidence and prevalence <strong>of</strong> gout in the<br />

US population.<br />

CASE PRESENTATION: An 88-year-old Cantonese woman with a past medical history <strong>of</strong> hypertension,<br />

Type-2 Diabetes mellitus, hyperlipidemia, chronic renal disease (creatinine 1.4) and gout presented with<br />

nausea and emesis <strong>of</strong> 24-hour duration. Additionally the patient complained about mild subjective<br />

fevers, loose stool and bloating, which commenced two weeks prior, when she had been started on<br />

allopurinol. On exam she was non-jaundiced, her abdomen was non-tender, non-distended and<br />

Murphy’s sign was absent. ALT (56), AST (55), Alkaline phosphatase (130) and lipase (334) were<br />

elevated. CT abdomen demonstrated a somewhat prominent 9 mm common bile duct. Despite<br />

antibiotic therapy for presumed cholangitis and simultaneously resolving pancreatitis, the patient<br />

deteriorated clinically. She developed a severe generalized maculopapular rash, leukocytosis (WBC 30),<br />

fever (39.7 degrees C) and acute interstitial nephritis. Transferred to the ICU for presumed sepsis, she<br />

was diagnosed with Allopurinol Hypersensitivity Syndrome. Over the next six weeks she improved with<br />

glucocorticoid treatment, hemodialysis and TPN. Her recovery was complicated by numerous severe<br />

electrolyte imbalances, uncontrolled diabetes and a gastrointestinal bleed secondary to stress and<br />

glucocorticoids. One year later her renal function is still compromised with a creatinine <strong>of</strong> 2.8 and she<br />

has developed pr<strong>of</strong>ound anemia.<br />

Immediate withdrawal <strong>of</strong> the <strong>of</strong>fending medication and supportive care are the mainstay <strong>of</strong> AHS therapy<br />

with possible benefit <strong>of</strong> systemic steroids if pulmonary, renal or myocardial involvement is present. The<br />

pathophysiology <strong>of</strong> AHS remains unclear, but is likely a complex interaction <strong>of</strong> immunology, drug<br />

metabolism, genetics, and infection with or reactivation <strong>of</strong> latent viruses.<br />

DISCUSSION: The severity <strong>of</strong> AHS, with its associated high mortality, acute morbidity and frequent<br />

long-term sequelae, warrants strict adherence to indications for allopurinol therapy. Identification <strong>of</strong><br />

risk factors such as advanced age, CKD, HCTZ or other diuretic use and the presence <strong>of</strong> the HLA-B*5801<br />

allele (prevalent in Asian populations), should also prompt the prudent use <strong>of</strong> allopurinol in select<br />

patient populations and therefore reduce the incidence <strong>of</strong> AHS. In patients with CKD, febuxostat and<br />

intra-articular steroids are effective and well-tolerated alternatives to allopurinol. For Asian populations<br />

preventive genetic testing for HLA B*5801 is becoming a possibility.<br />

A Deadly Combination!!<br />

Swapna P Busa, MD Ambar Rahman, MD Uzair Chaudhary, MD and Haifaa Abdulhaq, MD<br />

INTRODUCTION: Plasmablastic lymphoma (PBL) is an uncommon aggressive lymphoma arising most<br />

frequently in the oral cavity <strong>of</strong> HIV-infected patients. Amyloid light chain (AL) amyloidosis is a relatively<br />

uncommon disorder characterized by the deposition <strong>of</strong> amyloid fibrils in various tissues leading to<br />

progressive organ dysfunction and death. Ten to fifteen percent <strong>of</strong> multiple myeloma (MM) patients<br />

have extracellular deposition <strong>of</strong> amyloid in tissues resulting in amyloidosis. We report an unusual<br />

combination <strong>of</strong> cardiac amyloidosis, PBL and multiple myeloma in a 65year-old HIV negative woman. To<br />

our knowledge this is the first reported case <strong>of</strong> PBL with MM and amyloidosis.<br />

CASE PRESENTATION: 65 year old Caucasian woman with no past medical history presented with<br />

dyspnea on exertion and pedal edema and was found to have new onset heart failure. Her BNP was 871<br />

and troponin was 0.198. Her symptoms improved with diuresis and thoracentesis <strong>of</strong> a large left pleural<br />

effusion. Cytology was negative for malignancy. Patient refused further cardiac workup and was<br />

discharged home in improved clinical condition after medical management <strong>of</strong> heart failure.<br />

She returned four months later with worsening symptoms. Physical exam was notable for hypotension<br />

and respiratory distress. She was managed with inotropic agents and gentle diuresis. She had mild<br />

anemia but no hypercalcemia or renal dysfunction. Radiology revealed moderate bilateral pleural<br />

effusions. Histologic and immunohistochemical studies <strong>of</strong> the pleural fluid revealed kappa restricted<br />

large cell population with lymphoid features. The cells were positive for CD45, CD138 and MUM-1. They<br />

were negative for CD10, CD20, CD30, Human Herpes Virus 8 and Epstein bar virus(EBV) with the final<br />

diagnosis <strong>of</strong> PBL.<br />

SPEP showed no monoclonal gammopathy but kappa light chains were elevated with kappa to lambda<br />

ratio <strong>of</strong> 18.<br />

Echocardiogram revealed restrictive cardiomyopathy with speckled appearance suspicious for<br />

amyloidosis. Abdominal fat pad aspirate was negative for amyloidosis. Cardiac biopsy revealed AL type<br />

amyloid deposition with kappa restriction. Bone marrow biopsy revealed 60% monoclonal plasma cells.<br />

Skeletal survey done was negative for lytic lesions.<br />

Her clinical condition deteriorated rapidly and she died <strong>of</strong> cardiopulmonary arrest before chemotherapy<br />

was initiated.<br />

DISCUSSION: Cardiac amyloidosis commonly presents with fatigue, dyspnea and pedal edema. It is<br />

treated with systemic therapy which includes melphalan, bortezomib or cyclophosphamide based<br />

regimens. It carries poor prognosis with a median survival less than 6 months. PBL occurs most<br />

commonly in HIV patients, associated with EBV. In non HIV patients it is commonly EBV negative as in<br />

our patient. Treatment includes aggressive chemotherapy regimens however it carries poor prognosis as<br />

well with a median survival around 12 months. Our patient had cardiac amyloidosis, MM and PBL with a<br />

very poor overall prognosis.<br />

Calciphylaxis and the Abdominal Wound That Would Not Heal<br />

David J Cho, MD<br />

INTRODUCTION: Calciphylaxis must be considered in any patient with ESRD on hemodialysis presenting<br />

with painful, subcutaneous nodules or open wounds.<br />

CASE PRESENTATION: A 52 year old woman presented to the Emergency Department with a large<br />

right lower quadrant abdominal wound that had steadily increased in size over five months. Her medical<br />

history was significant for ESRD on hemodialysis, diabetes mellitus, coronary artery disease status post<br />

coronary-artery bypass grafting and hepatitis C. According to history obtained from the patient, the<br />

lesion first began as a painful, erythematous nodule on her lower right abdomen, and she received a<br />

course <strong>of</strong> Amoxicillin for suspected cellulitis. Her nodule continued to grow, however, and she<br />

underwent incision and drainage with additional antibiotics including Clindamycin for empiric coverage<br />

<strong>of</strong> methicillin-resistant staphylococcus aureus. The wound, now open, continued to rapidly expand with<br />

surrounding necrosis <strong>of</strong> the skin and subcutaneous tissues. She had several unsuccessful debridements<br />

performed at an outside hospital with further enlargement <strong>of</strong> the wound prior to admission. On physical<br />

exam, her abdominal wound measured approximately 12cm x 12cm and extended down to the<br />

abdominal fascia. The lateral edges showed evidence <strong>of</strong> necrosis without purulent drainage. In addition,<br />

she had several painful subcutaneous nodules on her left lower abdomen with mottling <strong>of</strong> the skin. She<br />

underwent debridement and eschar excision for the right lower quadrant abdominal wound the day<br />

after admission. The left lower quadrant subcutaneous nodules were not disturbed. Surgical tissue was<br />

sent for pathology and showed necrosis and calcification changes consistent with calciphylaxis.<br />

Vasculitic etiologies including cryoglobulins, C3 and C4 complement levels, anti-nuclear antibody, antineutrophil<br />

cytoplasmic antibodies, anti-lupus anticoagulant and anti-phospholipid antibodies were<br />

negative. When the diagnosis <strong>of</strong> calciphylaxis was established, the patient was started on a<br />

bisphosphonate, hyperbaric oxygen therapy and thiosulfate with dialysis. As her parathyroid hormone<br />

level was not markedly elevated for an ESRD patient on hemodialysis at 170 pg/mL, cinacalcet was not<br />

initiated. Despite medical management and one additional debridement and excision <strong>of</strong> necrotic tissue,<br />

the abdominal wound continued to enlarge without healing.<br />

DISCUSSION: Unfortunately, calciphylaxis is a rare and serious diagnosis that carries a very poor<br />

prognosis, with mortality as high as 80% after one year. While the mechanism <strong>of</strong> its pathogenesis is not<br />

clearly understood, it is most commonly seen in patients with ESRD on hemodialysis, and is<br />

characterized by systemic calcification <strong>of</strong> arterioles leading to ischemia and subsequent subcutaneous<br />

necrosis. The differential diagnosis also includes warfarin-induced skin necrosis and vasculitic etiologies<br />

noted above. Medical therapy is aimed at reducing systemic levels <strong>of</strong> calcium and phosphate levels. The<br />

usual cause <strong>of</strong> death from calciphylaxis is overwhelming sepsis from an associated infection <strong>of</strong> the<br />

wound.<br />

An Unlikely Foe: Iatrogenic multi-system organ dysfunction<br />

Allison S DeKosky, MD Manisha Israni, MD<br />

INTRODUCTION: Hospitalized patients are <strong>of</strong>ten treated aggressively with prolonged courses <strong>of</strong> broadspectrum<br />

antibiotics. These therapies can have unanticipated and severe adverse effects.<br />

CASE PRESENTATION: A 59 year-old man with diabetes, Stage I congestive heart failure, and COP on<br />

chronic steroids was admitted for surgical treatment <strong>of</strong> recurrent leg infections. He received two weeks<br />

<strong>of</strong> vancomycin and piperacillin-tazobactam before a flap repair. Intra-operative calcaneal and wound<br />

cultures grew pseudomonas and the patient was therefore switched to cefepime. Two weeks postoperatively,<br />

repeat deep wound cultures grew resistant enteroccoccus and the empiric vancomycin<br />

(restarted three days prior) was changed to linezolid; cefepime remained on medication list<br />

throughout. Four days later, he was found to be somnolent and confused. Computed tomography <strong>of</strong><br />

his brain was normal. Over the next twelve hours, his mental status worsened and he developed facial<br />

edema and a macular, confluent erythematous rash that spread from his torso to his face, ears, and<br />

upper extremities. There was no mucosal involvement. He became hemodynamically unstable with<br />

fever, tachycardia, hypotension and anuria. His creatinine had increased over the previous two days<br />

from 0.7 to 3, while maintaining a normal BUN. He developed leukocytosis with 3.5% eosinophils. His<br />

urinalysis revealed pyuria with no nitrite, bacteria or casts, consistent with acute interstitial<br />

nephritis. He ultimately required vasopressor support in the ICU and continuous veno-venous<br />

hemodialysis. Cefepime was then stopped and meropenem was initiated. Within a few days, his mental<br />

status and renal function improved. No organisms grew on multiple repeat blood and wound<br />

cultures. High-dose steroids were initiated for a concern <strong>of</strong> DRESS syndrome (Drug Rash, Eosinophilia<br />

and Systemic Symptoms). A biopsy <strong>of</strong> the rash revealed perivascular infiltrates containing eosinophils.<br />

DISCUSSION: Cefepime hydrochloride, a fourth-generation cephalosporin, is a common tool in<br />

physicians’ arsenals for treating severe infections, especially Pseudomonal infections. Prolonged use <strong>of</strong><br />

cefepime increases the risk <strong>of</strong> complications, which are compounded when renal function<br />

deteriorates. This patient had multiple cefepime-induced toxicities including interstitial nephritis,<br />

characterized by decreased GFR and pyuria in the absence <strong>of</strong> bacteria; severe neurotoxicity resulting in<br />

pr<strong>of</strong>ound encephalopathy, more likely to be seen with high doses <strong>of</strong> cefepime; and the less known<br />

DRESS syndrome. This drug hypersensitivity rash typically develops two to six weeks after the<br />

responsible drug is begun, consistent with this patient’s time course. Fever and erythroderma are<br />

common characteristics, while the facial edema and ear involvement are hallmark features. DRESS<br />

syndrome’s constellation <strong>of</strong> symptoms can be mistaken for sepsis-induced multi-organ failure or toxic<br />

shock syndrome. Internists should be aware <strong>of</strong> the unusual but critical complications associated with<br />

commonly used drugs like cefepime.<br />

Acquired Angioedema: A Rare Cause <strong>of</strong> Transient Bowel Obstruction<br />

Paul Di Capua, MD MBA, Radhika Zopey, MD, Stephen Kim, MD<br />

INTRODUCTION: : A 67-year old female with a history <strong>of</strong> marginal zone lymphoma and six-month<br />

history <strong>of</strong> recurrent episodes <strong>of</strong> abdominal pain requiring hospitalization presented to the emergency<br />

department with severe abdominal pain, multiple episodes <strong>of</strong> non-bloody emesis, and inability to<br />

tolerate oral intake.<br />

CASE PRESENTATIONOn exam, the patient was afebrile, hypotensive with a blood pressure <strong>of</strong> 64/36<br />

and a heart rate <strong>of</strong> 75 beats per minute. She was ill-appearing, diaphoretic, and had diffuse abdominal<br />

tenderness with voluntary guarding and mild distension. Laboratory tests were significant for a marked<br />

leukocytosis with lymphocytic predominance. A computed tomography scan <strong>of</strong> the abdomen revealed<br />

extensive bowel wall thickening <strong>of</strong> the entire length <strong>of</strong> small intestine with mesenteric fat<br />

stranding. The patient was treated with intravenous fluids and empiric antibiotics. Her symptoms<br />

completely resolved within 48 hours. Further laboratory testing revealed low C1 esterase inhibitor<br />

levels, low C4, and an undetectable C1q complement component, consistent with acquired<br />

angioedema. The patient’s acquired angioedema was attributed to her marginal zone lymphoma, and<br />

she is currently receiving treatment with rituximab.<br />

DISCUSSION: Acquired intestinal angioedema is a rare cause <strong>of</strong> transient, intermittent episodes <strong>of</strong><br />

bowel obstruction. This patient carried a diagnosis <strong>of</strong> splenic marginal zone lymphoma, which has<br />

previously been implicated in the depletion <strong>of</strong> C1-esterase inhibitor and the development <strong>of</strong> acquired<br />

angioedema. 1<br />

C1-esterase inhibitor deficiency can be inherited, or, more rarely, acquired, with just over 100 reported<br />

cases. 1 The acquired form is due to consumption <strong>of</strong> the C1-inhibitor through a paraneoplastic or an<br />

autoantibody-mediated reaction. 2 In the absence <strong>of</strong> the C1-inhibitor, there is intermittent, inappropriate<br />

activation <strong>of</strong> bradykinin, thought to mediate the angioedema symptoms seen in these patients. The<br />

clinical presentation <strong>of</strong> the hereditary and acquired forms <strong>of</strong> the disorder are similar, differing primarily<br />

with age <strong>of</strong> onset. 1 Hereditary angioedema typically presents before the age <strong>of</strong> 20 while the acquired<br />

form usually manifests after age 40. The angioedema episodes can last from two to five days, with<br />

episodic recurrence. Skin manifestations include a non-pitting, disfiguring edema <strong>of</strong> the face, limbs or<br />

genitals. Angioedema can also lead to life-threatening laryngeal and upper airway edema. Lastly, when<br />

the gastrointestinal tract is affected, bowel wall edema can cause transient bowel obstruction and<br />

severe abdominal pain.<br />

The diagnosis <strong>of</strong> angioedema requires low levels <strong>of</strong> C1-esterase inhibitor and C4. A reduced level <strong>of</strong> C1q<br />

establishes the diagnosis <strong>of</strong> acquired angioedema. 1 Treatment is generally focused on managing the<br />

associated condition.<br />

Blown Away: An Interesting Diagnosis <strong>of</strong> Anca-associated Vasculitis<br />

Renea Jablonski, MD<br />

INTRODUCTION: Microscopic polyangiitis (MPA) is a pauci-immune, small-vessel vasculitis that can<br />

present with a wide range <strong>of</strong> symptoms; the diagnosis <strong>of</strong> MPA in our patient was made all the more<br />

complex due to the absence <strong>of</strong> frank necrotizing vasculitis on biopsy. Often, as in this case <strong>of</strong> hemoptysis<br />

attributed to an ANCA-associated vasculitis, distinguishing between true vasculitis and psudovasculitis<br />

can be difficult, requiring close examination <strong>of</strong> the nuances <strong>of</strong> the presentation.<br />

CASE PRESENTATION: A 52 year-old Mexican woman with a history <strong>of</strong> arthritis treated with<br />

prednisone and methotrexate was admitted with 6 months <strong>of</strong> night sweats and low-grade fevers, two<br />

weeks <strong>of</strong> hemoptysis and a 17-kg weight loss. Physical exam revealed perforated nasal septum and<br />

diffuse rales without joint deformities or synovitis. Evaluation for pulmonary tuberculosis was negative,<br />

and the Pulmonary and Rheumatology services were consulted. Bronchoscopy was consistent with<br />

diffuse alveolar hemorrhage; subsequently the patient developed worsening hempoptysis, hypoxia and<br />

respiratory distress necessitating transfer to the medical intensive care unit. Further laboratory analysis<br />

was notable for an elevated ESR, positive p-ANCA (anti-MPO) and microscopic hematuria without<br />

proteinuria. Open lung biopsy showed organizing pneumonia and was negative for evidence <strong>of</strong><br />

vasculitis or granulomatous inflammation. Further history revealed ten years <strong>of</strong> cocaine abuse. The<br />

diagnosis was microscopic polyangiitis in light <strong>of</strong> her positive p-ANCA and anti-MPO antibodies though a<br />

pseudovasculitis secondary to cocaine abuse was strongly considered in the absence <strong>of</strong> vasculitis on lung<br />

biopsy. Treatment with pulse-dose methylprednisolone was started, and the patient was transitioned to<br />

a prednisone taper with cyclophosphamide. The patient continues to be on prednisone more than six<br />

months after discharge and has been without recurrent hemoptysis or joint complaints and regaining<br />

weight; follow-up imaging shows essentially complete resolution <strong>of</strong> organizing pneumonia.<br />

DISCUSSION: The diagnosis <strong>of</strong> the ANCA-associated vasculitidies <strong>of</strong>ten can be difficult; diagnosis is<br />

made using a combination <strong>of</strong> clinical signs, serologic markers and immunohistological findings. The<br />

history <strong>of</strong> cocaine use in this patient made the diagnosis more difficult as it can be associated with an<br />

ANCA-positive pseudovasculitis which mimics many <strong>of</strong> the clinical and laboratory features <strong>of</strong> the ANCAassociated<br />

vasculitidies without typical pathological findings <strong>of</strong> vasculitis. Distinguishing features <strong>of</strong><br />

cocaine-induced pseudovasculitis are an inconsistent ANCA pattern and target antibodies and the<br />

presence <strong>of</strong> anti-elastase antibodies. This patient lacked those findings and demonstrated a brisk<br />

response to treatment with corticosteroids and cyclophosphamide suggesting that this case in fact<br />

represents a case <strong>of</strong> microscopic polyangiitis. This patient had a ten year history <strong>of</strong> cocaine use and a<br />

three year history <strong>of</strong> myalgias and joint pain prior to development <strong>of</strong> hemoptysis; it is possible that the<br />

activation <strong>of</strong> an autoimmune process in this patient was triggered by chronic cocaine use.<br />

A Case <strong>of</strong> the Missing Goblet Cells<br />

Amirkaveh Mojtahed, MD, Ahmad Kamal, MD, Subhas Banerjee, MD, Teri Longacre, MD<br />

INTRODUCTION: Autoimmune enteropathy (AIE) is a rare autoimmune cause <strong>of</strong> intractable diarrhea in<br />

adults. Patients present typically with diarrhea, malnutrition, weight loss, and occasionally abdominal<br />

pain. This disease is characterized by gut autoantibodies and biopsy findings <strong>of</strong> intraepithelial<br />

lymphocytes, lack <strong>of</strong> goblet cells and villous blunting. The purported pathogenic theory suggests T cell<br />

dysfunction and a hyperactive immune system. Celiac disease (CD) must be excluded by celiac<br />

antibodies, trial <strong>of</strong> gluten free diet and CD susceptibility HLA genotype testing. While AIE is a recognized<br />

entity in pediatric gastroenterology literature, it is exceptionally rare in adults with fewer than 30 cases<br />

reported in the literature and only two conclusively associated with thymoma.<br />

CASE PRESENTATION: A 63 year-old man with a history <strong>of</strong> malignant thymoma resected 20 years<br />

earlier presented for evaluation <strong>of</strong> chronic diarrhea. He reported up to 10 watery bowel movements a<br />

day throughout the preceding year in addition to a 70 pound unintentional weight loss. His physical<br />

exam was normal. His past medical history was significant only for MGUS and thymoma. His hematocrit<br />

was 38.1%, ESR was 70 mm/hr and albumin was 3.2g/dl. Clostridium difficile toxin assay was negative,<br />

VIP was less than 15 pg/mL, and stool cultures were also negative. Celiac sprue studies including antigliadin,<br />

anti-endomysial and anti-tissue transglutaminase antibodies were also negative. A CT scan <strong>of</strong><br />

chest/abdomen/pelvis showed a 2.5 cm paraspinal mass and a 4 cm pleural based lesion suspicious for<br />

recurrent thymoma. EGD and colonoscopy revealed diffuse gastric erythema and mild flattening <strong>of</strong> the<br />

duodenal folds. Random duodenal biopsies showed absence <strong>of</strong> goblet cells, decreased Paneth cells,<br />

increased apoptotic bodies, and increased intraepithelial lymphocytes. Colonic biopsies showed similar<br />

findings. Overall, the histopathology was consistent with AIE. Serologic testing was positive for antigoblet<br />

cell antibodies. The patient’s prednisone was resumed at 40 mg/day with marked improvement<br />

<strong>of</strong> his diarrhea. Repeat biopsy 3 months later revealed continued loss <strong>of</strong> goblet cells with some Paneth<br />

cell regeneration.<br />

DISCUSSION: The first thymoma associated chronic diarrhea was described in 1966 followed by 4 cases<br />

<strong>of</strong> thymoma associated GVHD and 2 cases <strong>of</strong> thymoma associated AIE. It is possible that these cases as<br />

well as the current case all represent a similar disease process. The relapse <strong>of</strong> this patient’s malignant<br />

thymoma in temporal relation to the presentation <strong>of</strong> diarrhea strongly implicates the interrelation <strong>of</strong><br />

these conditions. Proliferating T cells within a thymoma could possibly result in unselected T cells<br />

entering the systemic circulation. These T cells would then orchestrate an autoimmune response<br />

primarily affecting intestinal epithelial cells causing mucosal damage and diarrhea. In summary, AIE is<br />

rare in adults, yet a high index <strong>of</strong> suspicion should be maintained for patients diagnosed as refractory<br />

sprue without positive antibodies or who present with chronic diarrhea and history <strong>of</strong> autoimmune<br />

disease or thymoma.<br />

Torsades De Pointes… Or Is It?<br />

Nima Naimi, DO<br />

INTRODUCTION: Torsades de pointes is a form <strong>of</strong> ventricular tachycardia associated with a long QT<br />

interval. It is defined by a gradual change in the amplitude and twisting <strong>of</strong> the QRS complex around the<br />

isoelectric line. Although rare, it is a life threatening arrhythmia accounting for almost 5% <strong>of</strong> all sudden<br />

cardiac deaths.<br />

CASE PRESENTATION: A 61 year old male with a history <strong>of</strong> alcoholic cirrhosis, stroke, diabetes, and<br />

seizures was admitted with shortness <strong>of</strong> breath and abdominal distention. On physical exam, he had<br />

increased ascities. CXR showed a pleural effusion. He was admitted to the medicine floor where he<br />

underwent paracentesis and thoracentesis. On the second day <strong>of</strong> hospitalization, the patient was found<br />

in the bathroom unresponsive. The rapid response team was called after glucose level, vitals, and EKG<br />

were found to be normal. A CT <strong>of</strong> the head did not find any acute changes. The patient was admitted to<br />

the ICU with acute encephalopathy. Hepatic encephalopathy was thought to be unlikely as the patient<br />

was taking lactulose and had 4 loose stools that day. No opioids or narcotics were given prior to the<br />

mental status change. Once placed on telemetry, his rhythm showed oscillating QRS complexes<br />

suggestive <strong>of</strong> torsades. No magnesium was given as his level was already elevated at 2.6, and his pulse<br />

did not match the rate on the monitor. EKG showed normal sinus rhythm with a rate <strong>of</strong> 81 while<br />

telemetry was still showing torsades. The cardiology fellow was called and recommended no treatment<br />

as the EKG was not consistent with torsades. Over the next day, telemetry demonstrated torsades<br />

intermittently. Neurology was consulted due to concern for silent seizures as the cause <strong>of</strong><br />

encephalopathy. EEG was consistent with status epilepticus at the same time that telemetry was<br />

showing torsades. The patient was given three doses <strong>of</strong> Ativan resolving both the status epilepticus on<br />

EEG and the torsades on telemetry. His mental status improved over the next several days, and he was<br />

discharged on higher doses <strong>of</strong> Keppra.<br />

DISCUSSION: It is imperative to treat torades promptly in order to prevent progression to ventricular<br />

fibrillation. However, if the pulse does not match the telemetry monitor and no change occurs in the<br />

blood pressure, an EKG should be ordered. As highlighted in this case, telemetry may erroneously sense<br />

electrical activity other than that from the heart.<br />

A Small Bowel Obstruction Caused by Mycobacterial Spindle Cell Pseudotumor<br />

Sajan Patel, MD Michael Pfeffer, MD David Geffen School <strong>of</strong> Medicine at UCLA<br />

INTRODUCTION: Mycobacterial spindle cell pseudotumor is an exceedingly rare tumor-like lesion<br />

characterized by spindle-cell and histiocyte proliferation secondary to mycobacterial infection. It usually<br />

affects immunosuppressed patients with or without AIDS and in most cases occurs in lymph nodes.<br />

CASE PRESENTATION: A 63 year-old man with a history <strong>of</strong> end-stage renal disease status post<br />

deceased donor renal transplant and small bowel carcinoid status post excision presented with fevers.<br />

Infectious work-up was negative, however a CT scan <strong>of</strong> the abdomen showed mural thickening and fat<br />

stranding around his small bowel anastomosis along with mesenteric lymphadenopathy. This raised<br />

concern for an infectious or inflammatory process or post-transplant lymphoproliferative disorder. The<br />

lymph nodes were not amenable to percutaneous biopsy by interventional radiology, and thus a biopsy<br />

was not pursued. His fevers eventually resolved with empiric antibiotics and he was discharged.<br />

On outpatient follow-up, an acid-fast bacilli urine culture from his hospitalization grew Mycobacterium<br />

avium-complex (MAC). He was prescribed azithromycin and ethambutol.<br />

The patient returned to the hospital several weeks later with left-sided abdominal pain and fevers. A CT<br />

scan <strong>of</strong> the abdomen showed a small bowel obstruction along with interval enlargement <strong>of</strong> the<br />

retroperitoneal lymph nodes seen on prior imaging. The patient underwent an exploratory laparotomy<br />

where a tumor was found in the mesentery at the site <strong>of</strong> the obstruction. This tumor was excised along<br />

with surrounding lymph nodes and the involved segment <strong>of</strong> small bowel. There was initial concern for<br />

recurrence <strong>of</strong> his carcinoid tumor or a lymphoma, however surgical pathology and culture identified the<br />

mass as a mycobacterial spindle cell pseudotumor secondary to MAC infection. The patient’s small<br />

bowel obstruction and fevers resolved after his surgery and he was discharged on a two-year course <strong>of</strong><br />

azithromycin and ethambutol.<br />

DISCUSSION: Mycobacterial spindle cell pseudotumor (MSP) is a rare presentation <strong>of</strong> mycobacterial<br />

infection. Less than 30 cases have been reported in the literature since 1985, when MSP was first<br />

described. To our knowledge, this is the first reported case <strong>of</strong> MSP causing a small bowel<br />

obstruction. Histologically, MSP has been described as an “exuberant spindle cell lesion” that<br />

“resembles a mesenchymal neoplasm”, including Kaposi’s sarcoma. Because <strong>of</strong> their shared histologic<br />

features and predilection for immunosuppressed hosts, proper identification is important as the two<br />

diseases have distinct prognoses and treatments.<br />

Conclusion: We present a case <strong>of</strong> Mycobacterium avium-complex that manifested as a mycobacterial<br />

spindle cell pseudotumor causing a small bowel obstruction. Although rare, this entity should be on the<br />

differential in an immunosuppressed patient with unexplained lymphadenopathy. Furthermore, since<br />

pseudotumor histologically resembles Kaposi’s sarcoma, differentiation is critical for treatment and<br />

prognostication purposes.<br />

Oriental Cholangiohepatitis: No Longer an Endemic Disease<br />

Rena H Shah, MD<br />

INTRODUCTION: As demographics around the world are shifting, the presentations <strong>of</strong> diseases are also<br />

changing. What once was only seen in Southeast Asia due to endemic pathogens has become a global<br />

phenomenon in recent years, and has introduced unique disease processes to Western medicine.<br />

CASE PRESENTATION: A 55 year-old Cantonese woman presented to the emergency room with one<br />

week <strong>of</strong> severe abdominal pain and emesis. On physical exam she was noted to be jaundiced and had<br />

severe tenderness to palpation at the right upper quadrant. Her labs were notable for an elevated<br />

alkaline phosphatase, direct bilirubinemia, and transaminitis. Her CT Abdomen revealed<br />

choledocholithiasis with extensive biliary and hepatic duct dilatation, as well as cholangitis, and a filling<br />

defect in the dilated biliary duct. . She was treated with IV piperacillin and metronidazole.<br />

Subsequently, the patient underwent ERCP for placement <strong>of</strong> an internal biliary drain for biliary<br />

decompression, and biopsy <strong>of</strong> the filling defect, which returned as a pigmented stone.<br />

Interestingly, she reported having experienced ten episodes <strong>of</strong> cholangitis over her lifetime. Between<br />

her bouts <strong>of</strong> cholangitis, she had suffered from chronic abdominal pain. She also reported spending 15<br />

years in Vietnam. This unusual and complex case sparked an interest on the medicine team, and after<br />

reading various case reports and reviews, we discovered that this presentation was consistent with<br />

Oriental Cholangiohepatitis (OCH). Prior to discharge, interventional radiology performed an internal to<br />

external biliary drain exchange that would remain indefinitely given the high likelihood that she would<br />

have recurrent stone formation. Since then she has routinely followed-up with the GI team, and remains<br />

pain free.<br />

DISCUSSION: OCH is an endemic disease in Southeast Asia, and its incidence is increasing in the West<br />

due to immigration from endemic countries. While the precise pathogenesis is unknown, it is believed to<br />

be a result <strong>of</strong> chronic infestation <strong>of</strong> the biliary tract with endemic parasites such as Clonorchis sinensis<br />

and Ascaris lumbricoides. OCH is characterized by recurrent attacks <strong>of</strong> abdominal pain, fever, and<br />

jaundice. Pathologically, the intra- and extrahepatic ducts are extensively dilated and contain s<strong>of</strong>t,<br />

pigmented stones and pus. It is crucial to understand this disease process as appropriate intervention<br />

can alter its otherwise recurrent nature and poor prognosis. Moreover this highlights the ever-changing<br />

face <strong>of</strong> medicine, and that as globalization progresses, epidemiology shifts, making it imperative for<br />

practitioners to familiarize themselves with disease processes that were once thought to be exclusive to<br />

a certain part <strong>of</strong> the world.<br />

Parasitosis Unexpectedly Causing Lymphoma-Like Symptoms in a Patient With AIDS.<br />

Alisson D Sombredero, MD, Howard Edelstein, MD<br />

INTRODUCTION: Fever <strong>of</strong> unknown origin (FUO) associated with pancytopenia, lymphadenopathy, and<br />

hepatosplenomegaly may be seen commonly in AIDS patients. Prevalent etiologies include M. avium<br />

complex, M. tuberculosis, histoplasmosis, coccidioidomycosis, cryptococcosis, and lymphoma. We<br />

present an unsuspected case <strong>of</strong> visceral leishmaniasis in a patient residing in the US, and show the utility<br />

<strong>of</strong> bone marrow biopsy in AIDS patients with FUO.<br />

CASE PRESENTATION: A 47 year-old Guatemalan male with history <strong>of</strong> HIV diagnosed in 2006 was<br />

treated with antiretrovirals and did well. In June 2010, after a 6 month trip to Arizona, he presented<br />

with a 3 month history <strong>of</strong> fevers, sweats, weight loss, and fatigue. The patient appeared toxic with a<br />

temperature <strong>of</strong> 38 C. Physical exam was notable for tachycardia and hepatosplenomegaly.<br />

Laboratory studies showed relative pancytopenia (WBC 4.9 th/µL, hemoglobin 7.6 g/dl and platelets<br />

27,000 th/µL), increased total protein <strong>of</strong> 11.0 g/dl and a normal CSF analysis. CD4 count was 62<br />

cells/mm3 and the HIV viral load was undetectable. The patient was admitted to the hospital for<br />

suspected disseminated coccidioidomycosis.<br />

The patient was initially treated with fluconazole, which was suspended after several days when<br />

cryptococcus and coccidioidomycosis serologies and cultures were normal. A CT scan <strong>of</strong> the abdomen<br />

and pelvis showed marked retroperitoneal lymphadenopathy, massive splenomegaly, and mild<br />

hepatomegaly. A diagnosis <strong>of</strong> lymphoma was considered. Due to a difficult percutaneous access <strong>of</strong> the<br />

involved lymph nodes, a bone marrow biopsy and aspirate was performed. Surprisingly, microscopic<br />

examination revealed amastigotes, consistent with a diagnosis <strong>of</strong> visceral leishmaniasis. The diagnosis<br />

was confirmed by the Centers for Disease Control by PCR with a leishmania titer 1:512.<br />

The patient was treated with liposomal amphotericin B for 10 days, followed by six weekly infusions.<br />

Several months later fatigue, pancytopenia, and elevated total protein recurred, and a bone marrow<br />

again showed amastigotes. The patient was re-induced with the same regimen <strong>of</strong> Amphotericin B,<br />

followed by 3 week suppressive therapy. He did well for several months but recently had his second<br />

clinical relapse. He is currently under re-treatment and doing well.<br />

DISCUSSION: Visceral leishmaniasis (with or without HIV infection) is a rare occurrence in patients<br />

residing in the United States. Based on the patient’s travel history, he was likely infected prior to 2006 in<br />

his home town <strong>of</strong> Jacaltenango, Guatemala, where visceral leishmaniasis is an endemic zoonosis with<br />

the dog as the reservoir. Interestingly, his infection remained asymptomatic for more than 4 years, even<br />

in the face <strong>of</strong> very advanced HIV disease. This case demonstrates that patients with HIV may have<br />

unusual or unsuspected opportunistic infections, and underlines the value <strong>of</strong> bone marrow biopsy in<br />

patients with FUO.<br />

Thyrotoxicosis Caused by a Complete Molar Pregnancy: An Unexpected Outcome in a Perimenopausal<br />

Woman<br />

Sowmya P Srinivasan, MD Kasandra White, MD, Erica Sobel, DO, Joan Lo, MD, Liz Han, MD Departments<br />

<strong>of</strong> Medicine and Obstetrics and Gynecology, Kaiser Permanente, Oakland, CA<br />

INTRODUCTION: Advanced complete molar pregnancies are an uncommon occurrence in the U.S.<br />

because <strong>of</strong> early detection with ultrasound and sensitivity <strong>of</strong> bhCG. Incidence rates <strong>of</strong> molar pregnancy<br />

in the U.S. are estimated at 1 in 2000 pregnancies. However, incidence is 5-15 fold higher in Asian<br />

countries, ranging from 1 in 500 pregnancies in Japan and Vietnam to as high as 1 in 120 pregnancies in<br />

Taiwan. Presenting symptoms <strong>of</strong> complete moles include abnormal uterine bleeding, preeclampsia,<br />

hyperemesis gravidarum, and increased uterine size (greater than dates). Hyperthyroidism can be<br />

evident biochemically, but initial presentation with thyrotoxicosis is rare. We present an unusual case <strong>of</strong><br />

thyrotoxicosis secondary to complete molar pregnancy.<br />

CASE PRESENTATION: A 52 year old Asian woman with no significant past medical history presented to<br />

the emergency department with shortness <strong>of</strong> breath and palpitations. On exam she had a normal heart<br />

rate, blood pressure and a positive stare without proptosis or lid lag. The thyroid was nontender,<br />

without enlargement or nodules. No tremor. Initial chest x-ray showed bilateral pleural<br />

effusions. Laboratory data revealed a suppressed TSH and elevated free thyroxine level consistent with<br />

thyrotoxicosis. Propranolol was started for symptom control, and differential diagnosis included<br />

thyroiditis versus possible Graves disease given recent atypical pneumonia. Lab returned a positive<br />

urine bHCG with a serum bHCG <strong>of</strong> 16,000 mIU/mL. Patient, when re-questioned, described two weeks <strong>of</strong><br />

abnormal vaginal bleeding. A transvaginal pelvic ultrasound showed an enlarged uterus with fibroids<br />

without intrauterine pregnancy. Endometrial biopsy completed for abnormal bleeding evaluation<br />

demonstrated necrotic tissue and chronic endometritis. Abdomen/pelvis CT scan showed no ovarian<br />

masses. Serial bHCG rose to 75,000 mIU/mL in conjunction with an elevated CA125. The patient<br />

underwent exploratory laparotomy and total abdominal hysterectomy with bilateral salpingoopherectomy.<br />

Pathology uncovered a hydatiform mole invading the myometrium with prominent<br />

vascular involvement. Per protocol <strong>of</strong> evaluating complete molar pregnancies, head and chest CT were<br />

performed to confirm the absence <strong>of</strong> metastatic disease. Postoperatively, bHCG declined to 28,000<br />

mIU/ml and methotrexate was initiated for post evacuation prophylactic chemotherapy. After three<br />

methotrexate cycles, bHCG levels were undetectable.<br />

DISCUSSION: The pathophysiology between molar pregnancy and hyperthyroidism involves homology<br />

between the beta-subunits <strong>of</strong> HCG and TSH. Thus, bHCG has a weak thyroid-stimulating activity. A<br />

pregnancy test should be considered in the evaluation <strong>of</strong> thyrotoxicosis in premenopausal women with<br />

symptoms suggestive <strong>of</strong> molar pregnancy, especially in those <strong>of</strong> Asian descent. A positive bHCG result in<br />

a hyperthyroid patient without interuterine pregnancy should also raise suspicion <strong>of</strong> molar<br />

pregnancy. While the sensitivity <strong>of</strong> ultrasound is greater for complete rather than partial moles, normal<br />

sonographic findings in a patient with abnormal bHCG should not preclude further investigation for<br />

gestational trophoblastic disease. Treatment <strong>of</strong> thyrotoxicosis in complete molar pregnancy is directed<br />

at the evacuation <strong>of</strong> the mole, resulting in bHCG decline and resolution <strong>of</strong> hyperthyroidism.<br />

Treatment Of Cirrhosis-associated Hyponatremia Refractory to Vasopressin 2-receptor Antagonist<br />

Ajay Yadlapati, MD; Minhtri Nguyen, MD<br />

INTRODUCTION: Hyponatremia is a common laboratory finding and reason for admission in patients<br />

with end stage liver disease (ESLD). Hyponatremia in the setting <strong>of</strong> cirrhosis is due to impaired water<br />

excretion resulting from persistent release <strong>of</strong> antidiuretic hormone (ADH) induced by diminished<br />

effective circulatory volume. In cirrhotic patients whose hyponatremia fails to correct with free water<br />

restriction, vasopressin 2 receptor antagonist is an effective alternative therapy. In this case report, we<br />

describe a patient with hepatorenal syndrome (HRS) whose hyponatremia failed to improve with<br />

tolvaptan and conivaptan but subsequently corrected with treatment with midodrine and octreotide.<br />

CASE PRESENTATION: A 51-year-old female with medical history significant for alcoholic cirrhosis and<br />

multiple admissions for hyponatremia was admitted for a serum sodium concentration <strong>of</strong> 118mmol/L<br />

associated with a serum and urine osmolality <strong>of</strong> 254 and 519mOsm respectively. The patient’s<br />

hyponatremia failed to improve with free water restriction. Therefore, tolvaptan (selective vasopressin-<br />

2 receptor antagonist) was started. Despite adequate up-titration over 96 hours, her serum sodium<br />

level remained relatively unchanged at a level <strong>of</strong> 120mmol/L. Due to the potential concern for<br />

inadequate gastrointestinal absorption <strong>of</strong> the drug, a decision was made to change from oral tolvaptan<br />

to intravenous conivaptan. Her serum sodium concentration minimally improved to 123mmol/L. On<br />

hospital day 13, the patient was started on midodrine and octreotide for treatment <strong>of</strong> acute kidney<br />

injury thought to be due to HRS, which slowly brought the patient’s serum sodium level from 122 to<br />

132mmol/L over a five day course coinciding with the resolution <strong>of</strong> the HRS. Repeat laboratory values<br />

revealed a stable serum sodium level <strong>of</strong> 135mmol/L nearly two weeks after initiation <strong>of</strong> the drugs.<br />

DISCUSSION: Hyponatremia is a common medical finding in patients with cirrhosis, and is a reflection<br />

<strong>of</strong> the severity <strong>of</strong> the underlying liver disease as well as a predictor <strong>of</strong> morbidity and mortality. As<br />

hyponatremia in these patients is due to excess total body water resulting from increased ADH secretion<br />

in response to the systemic vasodilation, free water restriction and vasopressin-2 receptor antagonist<br />

are the main therapeutic options. In our patient, both therapies failed and her hyponatremia persisted<br />

until she was started on midodrine (selective alpha-1 adrenergic agonist) and octreotide (a somatostatin<br />

analog) for treatment <strong>of</strong> HRS, which ultimately corrected her sodium. The lack <strong>of</strong> response to the<br />

vasopressin-2 receptor antagonists in our patient was likely due to avid renal proximal fluid reabsorption<br />

due to decreased effective circulatory volume, thereby resulting in diminished fluid delivery to the<br />

collecting tubule (which is the site <strong>of</strong> ADH action). The improvement in her hyponatremia with<br />

midodrine and octreotide was likely due to increased distal fluid delivery to the collecting tubule as<br />

reflected in the simultaneous increase in urinary output and relatively constant urinary osmolality. To<br />

date, this is the first case report <strong>of</strong> a cirrhotic patient with hyponatremia refractory to vasopressin-2<br />

receptor antagonists which resolved with treatment with midodrine and octreotide.<br />

Eosinophilia – A Red Flag for Identifying Lung Malignancy<br />

Stephanie Dizon, MBChB Secondary Authors: Christine Orr, MD, Brindusa Mocuanu, MD<br />

INTRODUCTION: Eosinophilia is described as an elevated blood eosinophil count above<br />

1500/microliter, <strong>of</strong>ten a non-specific finding with various etiologies including parasitic infections, allergic<br />

reactions, drug reactions and neoplastic disorders (1,2,3) . It is less <strong>of</strong>ten associated with solid tumor<br />

malignancies such as lung cancer, where the pathogenesis <strong>of</strong> eosinophilia is not well understood (4) .<br />

CASE PRESENTATION: An 80 year old man presented with a three day history <strong>of</strong> progressive<br />

generalized weakness and suffered from a fall. He described a rapid decline in carrying out normal<br />

activities <strong>of</strong> daily living. Constitutional symptoms <strong>of</strong> anorexia and a five-pound weight loss were<br />

apparent. His past medical history is significant for Chronic Obstructive Pulmonary Disease, angina,<br />

hypertension, and a previous coronary bypass operation. His smoking history is equivalent to 60 packyears.<br />

On examination he was wheezy and tachypneic, with good response to nebulized<br />

bronchodilators. He was hemodynamically stable, afebrile with normal oxygen saturations on room<br />

air. Respiratory examination revealed a diffuse expiratory wheeze, otherwise the remainder <strong>of</strong> the<br />

physical exam was normal. Initial lab results revealed a significant leukocytosis <strong>of</strong> 65,600/microL, with<br />

an eosinophil count <strong>of</strong> 27,550/microL (42%). Stools were examined for ova and parasites, Clostridium<br />

Difficile and culture, all <strong>of</strong> which were negative.<br />

A chest radiograph revealed a left upper lobe opacity, suspicious for an infective pneumonia or<br />

malignancy. This was followed by a CT chest/abdomen/pelvis which confirmed a 3.9cm x 2.9cm x 3.5cm<br />

mass in the apical segment <strong>of</strong> the left upper lobe. In addition, mediastinal lymphadenopathy, several<br />

adjacent pulmonary nodules and a large left pleural effusion were confirmed. A hypodense liver mass<br />

was also found suggesting a possible abscess or metastatic disease. A biopsy <strong>of</strong> the liver mass was more<br />

feasible and confirmed poorly differentiated non-small cell lung carcinoma (NSCLC). The left pleural<br />

effusion was subsequently drained and showed a culture-negative exudate with few atypical cells.<br />

As he had Stage IV lung carcinoma, he was not eligible for resection nor was he a candidate for palliative<br />

chemotherapy due to declining performance status. He was transferred to a palliative care unit for<br />

further symptomatic treatment.<br />

DISCUSSION: Eosinophilia in pulmonary malignancy occurs infrequently and is not well understood.<br />

The mechanism behind eosinophilia has been postulated as a GM-CSF driven process, where GM-CSF is<br />

produced in excess by malignant tumors, propagating leukocytosis (5) . Another case report <strong>of</strong> NSCLC<br />

found high Interleukin-5 levels as a possible driver for eosinophil production, activation and stimulation<br />

(3) . It is difficult to ascertain whether these eosinophilic-stimulating factors are a direct consequence <strong>of</strong><br />

solid tumors or a manifestation <strong>of</strong> a paraneoplastic process.<br />

In this case, the presentation <strong>of</strong> fatigue and eosinophilia revealed itself as lung cancer with subsequent<br />

imaging and histological analysis. In future cases <strong>of</strong> unexplained eosinophilia, further investigation for<br />

malignancy should be sought if the risk <strong>of</strong> cancer is suspected. Furthermore, the presence <strong>of</strong><br />

hypereosinophilia may act as a poor prognostic indicator in those with solid tumor cancers and <strong>of</strong>ten<br />

suggests metastatic disease.<br />

When "A Pain in the Neck" May Have Helped<br />

Sweatt, Andrew, MD.<br />

INTRODUCTION: Patients with fever <strong>of</strong> unknown origin (FUO) frequently endure prolonged<br />

hospitalization, and determining an etiology requires very thorough evaluation.<br />

CASE PRESENTATION: A 45 year-old Nepalese male immigrant presented with a three week course <strong>of</strong><br />

FUO. Febrile episodes occurred once daily and lasted two hours; they were associated with malaise,<br />

myalgias, diffuse arthralgias, occasional palpitations, frontal headaches, and 10-pound weight<br />

loss. Otherwise, complete review <strong>of</strong> systems was negative. Past medical history was only significant for<br />

malaria (treated in 2006) and latent tuberculosis (status post nine months <strong>of</strong> isoniazid in 2009). The<br />

patient was a non-smoker and denied use <strong>of</strong> alcohol or illicits. Since immigration to the U.S in 2008, he<br />

worked as a chef with no trips abroad. He took no prescribed medications.<br />

The patient had been admitted two weeks prior (for 3 days) with similar complaints and documented<br />

fever. Workup included unrevealing CXR, negative urinalysis, blood cultures without growth, normal<br />

head CT, and negative CSF studies. Following 24 hours without fever, he was discharged with<br />

presumptive diagnosis <strong>of</strong> viral syndrome and given return precautions. At re-admission the patient was<br />

found to be febrile to 39.3 degrees C, but had otherwise normal vitals. Abnormal findings on physical<br />

exam were limited to a slightly enlarged but non-tender thyroid, bilateral shotty supraclavicular<br />

lymphadenopathy, mild epigastric tenderness, and somewhat brisk but symmetric deep tendon<br />

reflexes. Initial evaluation included normal basic chemistry, borderline leukocytosis with 5% reactive<br />

lymphocytes, mild microcytic anemia, CXR without abnormalities, and unremarkable hepatic<br />

panel. Urinalysis was unrevealing, and urine/blood cultures were without growth. ESR was elevated at<br />

59, but extensive rheumatologic panel was negative. Iron studies were consistent with iron deficiency,<br />

but stool was guiac-negative. Two malaria smears drawn during febrile episodes showed no<br />

parasites. TTE was without valvular vegetations, rapid HIV was negative, and CT chest/abdomen/pelvis<br />

was not concerning for underlying malignancy or infectious source. A week into the course the patient's<br />

fevers persisted, he developed anterior neck pain with tenderness to palpation over the thyroid, and<br />

sinus tachycardia emerged with heart rates <strong>of</strong> 120-130. Finally, thyroid studies were performed<br />

revealing an undetectable TSH and elevated free T4 <strong>of</strong> 7.8 ng/dl. Subsequent thyroid ultrasound<br />

showed a hyperemic, heterogeneous gland consistent with thyroiditis. There was no thyroid uptake on<br />

radioactive iodine scan. Serum thyroglobulin was elevated at 241 ng/dl, but thyroglobulin and thyroid<br />

peroxidase antibodies were undetectable. This constellation <strong>of</strong> findings was compatible with toxicphase<br />

subacute granulomatous thyroiditis. Beta-blocker and NSAID therapy was used for supportive<br />

management. Ultimately, the patient's fevers, tachycardia, and symptoms resolved and he was<br />

discharged home.<br />

DISCUSSION: This case stresses the importance <strong>of</strong> casting a wide net in the diagnosis <strong>of</strong> FUO, and<br />

demonstrates an atypical presentation <strong>of</strong> de Quervain’s thyroiditis (initial lack <strong>of</strong> neck pain and<br />

euthyroid appearance). The patient’s hospital course serves to remind the internist to frequently<br />

reassess a patient with interval history/exam. Extensive and costly imaging was performed early, prior<br />

to consideration <strong>of</strong> thyroid studies. An adept clinician understands when to allow a stable patient’s<br />

diagnosis to better declare itself, which <strong>of</strong>ten leads to a cost-efficient work-up at no expense to patient<br />

safety.<br />

Intractable New Onset Seizures and Worsening Bizarre Behavior: CONVERSION DISORDER OR IS THERE<br />

AN ALTERNATIVE DIAGNOSIS?<br />

Jodie A Barr, DO, Bryan Wert M.D., Cuong Doan M.D., FACP, Exempla Saint Joseph Hospital, Denver, CO<br />

INTRODUCTION: This case describes a 20 year old male with grand mal seizures and bizarre behavior<br />

thought to have conversion disorder. Workup revealed a rare alternative diagnosis showing the<br />

importance <strong>of</strong> a broad differential.<br />

CASE PRESENTATION: A 20 year old male presented to an outside hospital with a witnessed grand mal<br />

seizure described as pill rolling and left clenched fist. He was started on Keppra without improvement<br />

after a negative initial workup including lumbar puncture and EEG. On transfer to Exempla Saint Joseph<br />

Hospital (ESJH) the patient was alert and intermittently exhibited purposeful movement <strong>of</strong> his left arm.<br />

The initial admitting diagnosis was pseudo seizures versus conversion disorder. On further observation,<br />

the patient was intermittently catatonic and at other times was agitated with choreathetosis on exam,<br />

hyperactive reflexes throughout and decreased verbal output. He also showed autonomic instability<br />

with tachycardia and hypertension. A repeat EEG showed right sided slowing with intermittent sharp<br />

waves. A repeat LP showed pleocytosis with positive NMDA receptor antibody IgG in the CSF and in the<br />

serum. He was diagnosed with anti-NMDA receptor associated encephalitis and started on IVIG and<br />

high dose solumedrol for 5 days. He had minimal improvement and Rituxan was started with resolution<br />

<strong>of</strong> seizures, autonomic instability, and catatonia. He continued to have behavioral outburst but<br />

managed with Seroquel and Ativan.<br />

DISCUSSION: This case illustrates a rare disease, anti-NMDA receptor encephalitis, in a young male<br />

without a clear precipitant. Anti-NMDA receptor encephalitis was recently discovered in 2007, and<br />

involves the formation <strong>of</strong> antibodies against the NR1 receptor. The frequency <strong>of</strong> this disease is<br />

unknown, but a population based prospective study in the UK showed 4% <strong>of</strong> patients with anti-NMDA<br />

receptor encephalitis. The majority <strong>of</strong> patients are between 19-24 years with younger patients less<br />

likely to have associated tumors. 70% <strong>of</strong> patients present with viral prodrome with progression to<br />

agitation, bizarre behavior, or<strong>of</strong>acial and limb dyskinesia, choreathetosis, seizure, catatonia, and<br />

autonomic instability. Associated tumors include testicular germ cell tumors, teratoma, and Hodgkin<br />

lymphomas. Treatment consists <strong>of</strong> immunotherapy with IVIG, steroids, and removal <strong>of</strong> the tumor if<br />

appropriate, but there is no standard <strong>of</strong> care. Second line treatments include Rituxan and<br />

cylophophamide. 75% <strong>of</strong> patients have full recovery, but have protracted hospital courses mostly due to<br />

behavioral disturbance. Our case demonstrates a rare disease, anti-NMDA receptor encephalitis,<br />

presenting with seizures and bizarre behavior, with initial diagnosis <strong>of</strong> conversion disorder. This case<br />

shows the importance <strong>of</strong> keeping a broad differential and provides further data regarding treatment <strong>of</strong><br />

anti-NMDA receptor encephalitis and its associated behavioral disturbances.<br />

The "Natural" Course <strong>of</strong> M. Kansasii<br />

Ryan Borne, MD, Mark Reid, MD, Gaby Frank, MD<br />

INTRODUCTION: In the modern era, it is uncommon to witness the natural course <strong>of</strong> certain diseases,<br />

especially those with good response to available treatments. Chronic pulmonary disease caused by<br />

Mycobacterium kansasii is amongst these maladies. We present a case <strong>of</strong> natural progression <strong>of</strong><br />

pulmonary M. kansasii infection after the patient chose a “non-traditional” treatment option.<br />

CASE PRESENTATION: A 58-year-old female presented with progressively worsening shortness <strong>of</strong><br />

breath over years with rapid worsening over the previous weeks. Her medical history is notable for<br />

progressive pulmonary disease secondary to M. kansasii diagnosed three years prior. At that time it was<br />

recommended that she undergo antimicrobial therapy, however she declined and pursued a “natural”<br />

approach. Nevertheless, she never consulted a licensed naturopathic provider. Upon admission, her<br />

physical exam was notable for cachexia and bilateral pulmonary rales. Chest radiograph (CXR)<br />

demonstrated worsening fibro-nodular densities with cavitary change. Computerized tomography (CT)<br />

<strong>of</strong> the chest revealed similar changes with large areas <strong>of</strong> cavitation. Multiple sputum cultures grew M.<br />

kansasii. She agreed to a 12- month, three-drug regimen consisting <strong>of</strong> rifampin, isoniazid, and<br />

ethambutol. After one month <strong>of</strong> therapy she developed respiratory failure and was transferred to<br />

hospice.<br />

DISCUSSION: Alternative medicine, also known as complementary, integrative, or unconventional<br />

medicine (CAM), is functionally defined as interventions neither taught widely in medical schools nor<br />

available in many US hospitals. The popularity <strong>of</strong> CAM is rising, with up to 75% <strong>of</strong> patients in some<br />

series pursuing an alternative approach as part <strong>of</strong> their health care. While there is an increasing<br />

demand for personalized medicine, the rush to embrace new alternative therapies should be<br />

approached with great caution and only by licensed providers. Although CAM therapies are popular,<br />

they have not been subjected to significant rigorous studies and therefore there are not evidence-based<br />

guidelines. Factors attracting patients to CAM include dissatisfaction with conventional medicine and a<br />

holistic orientation to health, illness and treatment, among others. Currently, naturopathic medicine<br />

does not <strong>of</strong>fer an option for M. kansasii treatment, whereas the <strong>American</strong> Thoracic Society and<br />

Infectious Disease Society <strong>of</strong> America consensus guidelines for the treatment <strong>of</strong> M. kansasii are based<br />

on category A, grade II evidence level. When pulmonary M. kansasii disease is left untreated, its<br />

mortality can reach 50%, decreasing to 2-11% when appropriate treatment is instituted.<br />

When left to nature, M. kansasii can cause devastating illness. We emphasize the importance <strong>of</strong><br />

educating and understanding patients’ misconceptions on both conventional and alternative medicine<br />

to help optimize their healthcare experience.<br />

A Common Drug, an Uncommon Problem: Statin-Associated Weakness and Confusion<br />

Christopher B Estopinal, MD, Michael J Sampognaro, MD<br />

INTRODUCTION: Statins are well tolerated, widely prescribed medications used to control<br />

hyperlipidemia. Although rare, cognitive side effects have been reported in drug registries and in a<br />

small number <strong>of</strong> case reports. This case highlights the association between statins and neurocognitive<br />

disturbances.<br />

CASE PRESENTATION: An 80-year-old male presented to his primary care physician complaining <strong>of</strong><br />

lower extremity weakness, ataxia, joint pain, and scalp numbness. His past medical history was<br />

significant for hyperlipidemia, well-controlled diabetes mellitus type 2, hypertension, factor VIII<br />

deficiency, and mild neur<strong>of</strong>oraminal and lumbar spinal stenosis. His home medications included<br />

atorvastatin, metformin, sitagliptin, olmesartan, and hydrochlorothiazide. He consumed approximately<br />

two alcoholic beverages a week and was a former smoker; he intermittently used a cane when<br />

ambulating due to left knee pain. Review <strong>of</strong> symptoms was notable for a resolving upper respiratory<br />

infection. Physical exam was within normal limits barring mild incoordination on neurological<br />

exam. Laboratory studies, including complete blood count, electrolytes, thyroid stimulating hormone,<br />

vitamin B12, and creatine phosphokinase, were all within normal limits. An MRI study <strong>of</strong> the brain was<br />

unrevealing. The patient’s statin was discontinued, and his symptoms resolved within a week.<br />

Nine months later, the patient presented to the hospital with progressive weakness <strong>of</strong> his lower<br />

extremities, waxing and waning confusion, hallucinations, and falls. He also reported numbness <strong>of</strong> the<br />

extremities in a stocking-glove distribution and hypoesthesia <strong>of</strong> the scalp. A physician not aware <strong>of</strong> the<br />

patient’s previous statin intolerance had initiated pravastatin therapy two months prior to his<br />

presentation. The patient had discontinued his pravastatin four days prior to admission; his confusion<br />

had resolved but none <strong>of</strong> his other symptoms had improved. Physical examination revealed decreased<br />

proximal lower extremity strength, diffuse hyporeflexia, and a wide-based gait. Laboratory testing,<br />

including creatine phosphokinase, was once again unrevealing. MRI studies <strong>of</strong> the head, cervical spine,<br />

thoracic spine, and lumbar spine were within normal limits for age; carotid ultrasound revealed no<br />

significant atherosclerosis. The patient’s symptoms completely resolved after several days <strong>of</strong> inpatient<br />

observation and were attributed to statin intolerance. His hyperlipidemia is now managed with<br />

colesevelam, and he has been without the reported constellation <strong>of</strong> symptoms for almost two years.<br />

DISCUSSION: While statins are generally well tolerated, there is an emerging literature describing<br />

statin-associated neurocognitive side effects. Our patient exhibited adverse neurocognitive reactions<br />

associated with statins both on initial treatment and on rechallenge. The effect <strong>of</strong> statins on cognitive<br />

function is controversial; both increased and decreased cognitive function has been associated with<br />

their use. Proposed mechanisms for statin-associated cognitive impairment include disruption <strong>of</strong><br />

synaptic function through suppression <strong>of</strong> nuclear factor-[kappa]B and tumor necrosis factor as well as<br />

modification <strong>of</strong> cell membrane composition. While not commonly associated with neurocognitive<br />

impairment, statins should be considered during the workup <strong>of</strong> confusion in an elderly patient.<br />

Subacute Inflammatory Demyelinating Polyneuropathy (SIDP) in a Patient who had Recently<br />

Completed the hCG Diet<br />

Shai Feingold, DO<br />

INTRODUCTION: Acute inflammatory demyelinating polyneuropathy (AIDP) is a rare disease, affecting<br />

1-2 people per 100,000 annually. I present a case <strong>of</strong> a patient who had recently completed the hCG diet,<br />

which I hypothesize triggered an autoimmune reaction that led to the demyelination response.<br />

CASE PRESENTATION: A 44-year-old man presented to a neurologist with a 5.5-week history <strong>of</strong> tingling<br />

that began in his toes. He developed weakness and numbness in his legs that ascended to his hands and<br />

arms. He could not rise from a chair and fell 5 times. He denied any recent illnesses, immunizations or<br />

surgeries. Upon presentation, numbness was present up to the T6 dermatome. An EMG showed only<br />

diffuse slowing. Deep tendon reflexes were absent. A presumptive diagnosis <strong>of</strong> inflammatory<br />

demyelinating polyneuropathy was made and the patient was referred to this hospital for further<br />

treatment.<br />

CSF from lumbar puncture was normal except for a protein <strong>of</strong> 70. West Nile, VZV, HSV and enterovirus<br />

were negative. ANA, ANCA and rheumatoid factor were also negative. MRI <strong>of</strong> the brain and c-spine<br />

showed no abnormalities. Multiple sclerosis protein banding was negative. The patient received<br />

400mg/kg <strong>of</strong> IVIg for 5 days. By the fifth day the patient was able to rise from a chair and flex his hips to<br />

60 degrees (at admission he could flex to 5 degrees). Numbness had regressed to the T10 dermatome.<br />

He was able to walk short distances with minimal instability, and was discharged on hospital day 5.<br />

DISCUSSION: The patient had completed the hCG diet two weeks before the onset <strong>of</strong> symptoms. This<br />

diet entails eating a 500kcal, fat-free diet for 3.5-6 weeks, accompanied by daily sublingual or<br />

intramuscular administration <strong>of</strong> 125 IU <strong>of</strong> hCG. The diet theoretically prompts the body to develop a<br />

hypermetabolic state, which combined with low caloric intake, forces the body to utilize its energy<br />

reserves. I propose that the hCG acted as a foreign antigen, resulting in an immune response. In 70% <strong>of</strong><br />

AIDP cases, a preceding trigger, such as a viral illness, immunization or surgery is identified. This trigger<br />

prompts both cellular and humoral immune responses that lead to an attack on the peripheral nervous<br />

system due to molecular mimicry. Findings include a partial nerve conduction block and slowing <strong>of</strong><br />

conduction velocity, symmetric involvement <strong>of</strong> arms and legs in distal and proximal musculature,<br />

reduced or absent deep tendon reflexes and increased CSF protein without pleocytosis. Treatment<br />

includes IVIg, plasma exchange or steroids. In AIDP the nadir <strong>of</strong> symptoms occurs within 3-4 weeks <strong>of</strong><br />

the immunologic trigger. In this case the nadir occurred 7.5 weeks after finishing the diet, consistent<br />

with SIDP, in which the nadir occurs 4-8 weeks after exposure. There are no reports <strong>of</strong> the hCG diet<br />

leading to AIDP; however this case highlights a potential risk from this controversial diet.<br />

The Cause <strong>of</strong> a Pause is Not Always Cardiac<br />

Jonathan G. Schwartz, M.D.1, Robert S. Schwartz, M.D.2, Joel A. Garcia, M.D.1,3,4 1Department <strong>of</strong><br />

Medicine, University <strong>of</strong> Colorado Denver, Aurora, Colorado, 2Minneapolis Heart Institute Foundation,<br />

Minneapolis, Minnesota, 3Department <strong>of</strong><br />

INTRODUCTION: A 49 year-old previously healthy man was referred to clinic for follow-up after dual<br />

chamber pacemaker implantation performed one week previously. The patient was on vacation one<br />

week prior when he suddenly felt faint and lost consciousness while crossing the street with his wife. He<br />

became unresponsive with no pulse, and his wife immediately began CPR. Shortly thereafter, the patient<br />

developed pulses and regained consciousness. Upon EMS arrival, he again went pulseless, followed by a<br />

generalized seizure, with subsequent return <strong>of</strong> pulses. ECG showed extreme bradycardia and sinus<br />

arrest.<br />

CASE PRESENTATION: Upon hospital arrival, he again developed prolonged asystole, requiring<br />

intubation. Head CT, cardiac echo, and metabolic panel were unremarkable. A temporary pacemaker<br />

was inserted, followed by permanent pacemaker implantation. After routine pacemaker check, the<br />

patient returned home. Two days later, he presented to the ED with nonspecific ‘dizzy’ episodes.<br />

Pacemaker interrogation was unremarkable, and the patient was referred to outpatient followup.<br />

Head CT with contrast was ordered since MRI could not be performed, given the pacemaker. The<br />

CT revealed a right temporo-parietal lesion, and MRI was required to characterize this potential<br />

lesion. MRI was pursued, and the pacemaker mandated temporary reprogramming during brain MRI<br />

imaging. A special, low-energy MRI protocol was used, and a cardiologist monitored the patient during<br />

the entire MRI scan. MRI revealed a high-grade glioblastoma multiforme (GBM) in the temporal lobe.<br />

EEG and specialist consultation suggested the cause <strong>of</strong> his lightheadedness and asystole was likely<br />

temporal lobe seizure. The pacemaker was removed to perform functional MRI. MRI during reading<br />

aloud, tongue tapping, and left finger tapping showed neurosurgical resection could be undertaken<br />

without impacting key vision, speech, or motor centers. Diffusion tensor imaging showed the right optic<br />

radiation was displaced but not interrupted by the tumor. The tumor was resected and GBM confirmed.<br />

A permanent, MRI-compatible pacemaker was placed as he is at risk for seizures and will need<br />

surveillance MRI imaging.<br />

DISCUSSION: Several important clinical points are illustrated by this case. Temporal lobe seizures<br />

causing bradycardia are rare, cause SA arrest rarely, but should be considered in cases <strong>of</strong> sinus arrest.<br />

Secondly, brain MRI imaging can be performed safely in patients with traditional pacemakers, even if<br />

not identified as MRI-compatible, using low energy scan sequences. Finally, functional MRI can identify<br />

local cellular activity with overlays on anatomic images. DTI shows brain tracts by imaging water<br />

molecule diffusion.<br />

New Diagnosis <strong>of</strong> Sarcoidosis Presenting as Ventricular Tachycardia<br />

Amy M Silverberg, MD Amy Silverberg, MD and Robert E. Burke, MD<br />

INTRODUCTION: With ventricular arrhythmias related to coronary artery disease increasingly common<br />

in the inpatient setting, physicians should remain alert to the nonischemic causes <strong>of</strong> ventricular<br />

tachycardia and be comfortable with the role <strong>of</strong> cardiac MRI in the diagnosis <strong>of</strong> myocardial pathology.<br />

CASE PRESENTATION: A 65 year- old man presented with three months <strong>of</strong> cough and dyspnea on<br />

exertion that he first noted after moving to 8000 feet <strong>of</strong> elevation. He denied fever, rash, syncope,<br />

chest pain, palpitations, orthopnea, and lower extremity edema. He reported a 50 pack-year history <strong>of</strong><br />

cigarette use with cessation two months prior. Physical exam revealed a well-appearing man with<br />

normal vital signs on room air. While his heart sounds were regular, every other cardiac cycle was s<strong>of</strong>ter<br />

to auscultation and was not transmitted to the radial pulse. EKG and telemetry revealed right bundle<br />

branch block and a predominant rhythm <strong>of</strong> ventricular bigeminy as well as periods <strong>of</strong> normal sinus<br />

rhythm intermixed with episodes <strong>of</strong> regular, monomorphic, wide-complex tachycardia. Transthoracic<br />

echocardiogram revealed mild biventricular systolic dysfunction; there was no obstructive coronary<br />

disease on catheterization. Moderate upper-lobe-predominant centrilobular emphysema with<br />

mediastinal and hilar adenopathy were seen on CT <strong>of</strong> the chest. Cardiac MRI with gadolinium revealed<br />

focal areas <strong>of</strong> delayed contrast enhancement <strong>of</strong> the anterior and basal septum as well as the basal<br />

lateral wall.<br />

DISCUSSION: Conduction abnormalities and ventricular arrhythmias are commonly seen by the<br />

internist, particularly in the hospital setting. In a patient without coronary artery disease, the finding <strong>of</strong><br />

ventricular tachycardia (VT) mandates methodical investigation to identify other, less common<br />

etiologies. In such cases, cardiac MRI is becoming the test <strong>of</strong> choice for investigating abnormalities <strong>of</strong><br />

the myocardium that predispose to VT. Although this patient was asymptomatic with regard to his VT,<br />

the finding <strong>of</strong> hilar lymphadenopathy coupled with his MRI findings was diagnostic <strong>of</strong> cardiac sarcoidosis<br />

(CS). CS most <strong>of</strong>ten involves the left ventricular myocardium and can manifest as electrical dysfunction,<br />

including high-degree atrioventricular block, bundle-branch block, and ventricular<br />

tachycardia. Endomyocardial biopsy is an insensitive test for CS because <strong>of</strong> patchy involvement <strong>of</strong> the<br />

myocardium by granulomas and because the usual biopsy site is not the most common site <strong>of</strong><br />

granuloma formation. As a noninvasive diagnostic modality, cardiac MRI has higher specificity than PET<br />

scan and higher sensitivity than endomyocardial biopsy.<br />

Stumbling Drunk With Vitamin B12 Deficiency<br />

Keith Wells, MD, Philip Fung, MD<br />

INTRODUCTION: Vitamin B12 deficiency <strong>of</strong>ten presents with fatigue and macrocytic anemia with or<br />

without neurologic symptoms. Causes include poor dietary intake, malabsorbtive states, and<br />

autoimmune causes. We describe a case <strong>of</strong> vitamin B12 deficiency with subacute combined<br />

degeneration from chronic alcoholic gastritis and H. pylori infection.<br />

CASE PRESENTATION: A 61-year-old male presented with 1 week <strong>of</strong> falling and progressive leg<br />

weakness. The patient also described 3 months <strong>of</strong> progressive, painless numbness and tingling <strong>of</strong> his<br />

feet bilaterally with an inability to accurately place his feet while walking. For the past year, the patient<br />

reported decreased oral intake with prandial nausea and vomiting and a 30 pound weight loss. His only<br />

medications were vitamins, including B12, started 1 week prior to admission at the insistence <strong>of</strong> family.<br />

Past medical, surgical and social history were unremarkable, except heavy alcohol use with 10 shots <strong>of</strong><br />

vodka daily.<br />

Initial assessment revealed a cachectic man. Neurologic exam showed decreased muscle bulk with<br />

normal tone. Muscle strength was symmetrically diminished to 4/5 in flexors and extensors in the legs<br />

and feet. The lower extremities had diminished sensation to light touch and vibration, an inability to<br />

distinguish sharp and dull, and a complete loss <strong>of</strong> positional sensation <strong>of</strong> the toes and ankle. Sensation<br />

in the upper extremities was normal. Patellar and achillies reflexes were absent. His gait was ataxic and<br />

stamping. Laboratory analysis showed a macrocytic anemia (hemoglobin <strong>of</strong> 9.8 g/mL, MCV 106.4 fL)<br />

with borderline low vitamin B12 levels (318 pg/mL). Subsequent lab tests revealed an elevated<br />

homocysteine level (16 µmol/L) and an elevated methylmalonic acid level (0.30 µmol/L). An antibody<br />

screen for anti-intrinsic factor was negative. H. pylori IgG antibodies were positive. Brain and spine MRI<br />

imaging failed to show any acute intracranial or cord process. An upper endoscopy showed chronic<br />

gastritis. A diagnosis <strong>of</strong> subacute combined degeneration was made with Neurology in agreement. The<br />

patient was started on intramuscular vitamin B12 injections, a proton pump inhibitor, and triple<br />

antibiotic therapy for H. pylori. The patient was discharged after physical therapy clearance with mildly<br />

improved neurologic sensation.<br />

DISCUSSION: Alcohol abuse is a prevalent problem in hospital and clinic settings. In our patient,<br />

chronic alcoholic gastritis led to both deficient vitamin B12 intake and decreased absorption. Gastritis<br />

reduces stomach acid production leading to decreased dissociation <strong>of</strong> vitamin B12 from food. Also,<br />

inflammation <strong>of</strong> the gastric mucosa may lead to decreased production <strong>of</strong> intrinsic factor by parietal cells.<br />

H. pylori has also been implicated in association with vitamin B12 deficiency with gastritis and may be<br />

under diagnosed. Vitamin B12 supplementation may reduce neurologic damage, but outcomes are not<br />

predictable. Our case <strong>of</strong> represents an unusual complication from the very common problem <strong>of</strong> alcohol<br />

abuse.<br />

Try and Try Again, A 52 Year-Old Man Presenting with Cardiac, Renal and Hepatic Dysfunction<br />

Chi Zheng, MD, University <strong>of</strong> Colorado School <strong>of</strong> Medicine, Aurora, CO, Rebecca Hanratty, MD, Denver<br />

Health, Denver, CO<br />

INTRODUCTION:<br />

CASE PRESENTATION: A 52 year-old man was admitted with cardiac and renal failure after he<br />

presented with one month <strong>of</strong> weight gain, lower extremity edema, dyspnea and orthopnea. His exam<br />

revealed a S3 gallop, elevated jugular venous pressure, rales, and hepatomegaly. His serum creatinine<br />

was 3.1 mg/dL. Serum electrolytes were normal. He had a mild macrocytic anemia. Aminotransferases<br />

were slightly elevated around 60 U/L. Total bilirubin was 2.8 mg/dL, direct bilirubin 2.3 mg/dL, and<br />

alkaline phosphatase and gamma-glutamyl gransferase were elevated at 444 U/L and 342 U/L,<br />

respectively. Brain natriuretic peptide was 3054 pg/mL. Urinalysis showed 2 plus protein, without casts<br />

or blood; proteinuria quantified to 897 mg/24 hours. Electrocardiogram showed inferior Q-waves. Mild<br />

hepatosplenomegaly and renomegaly were found on ultrasound. Echocardiogram showed mild<br />

concentric left ventricular hypertrophy with moderate biatrial dilation and near-normal systolic function.<br />

Patient’s serum protein electrophoresis (SPEP) and 24-hour urinary electrophoresis (UPEP) with<br />

immun<strong>of</strong>ixation showed albumin predominance without monoclonal proteins. Serum angiotensin<br />

converting enzyme level was normal as were serum ferritin and iron saturation. Abdominal fat pad and<br />

liver biopsies were negative with Congo Red staining. Patient was discharged with a presumptive<br />

diagnosis <strong>of</strong> restrictive cardiomyopathy along with congestive hepatopathy and cardiorenal<br />

syndrome. The patient returned 6 weeks later with symptoms <strong>of</strong> worsening heart failure. His serum<br />

calcium on admission had increased to 12.5 mg/dL with a creatinine <strong>of</strong> 5.4 mg/dL. A computed<br />

tomography <strong>of</strong> the chest revealed a new left 8 th rib lesion; biopsy <strong>of</strong> which was consistent with a plasmacell<br />

neoplasm. Repeat SPEP showed two faint monoclonal bands in the kappa lane. Serum kappa free<br />

light chain was elevated at 600 mg/dL and the kappa:lamda ratio was 243. Elevated kappa light chain<br />

was also seen on repeat UPEP. Bone marrow biopsy showed extensive involvement by a kappa light<br />

chain-restricted plasma cell myeloma. Patient was diagnosed with multiple myeloma with light chain<br />

deposition disease (LCDD).<br />

DISCUSSION: Our patient presented with restrictive cardiomyopathy, renal failure and hepatomegaly.<br />

Amyloidosis was considered but none <strong>of</strong> our patient’s biposies stained with Cong Red. LCDD has a<br />

similar presentation with similar organ involvement as AL amyloidosis. However, monoclonal light chain<br />

fragments, typically kappa, deposit in organs without formation <strong>of</strong> amyloid fibrils and therefore do not<br />

stain with Congo Red. As in our patient, routine SPEP and 24-hour UPEP with immun<strong>of</strong>ixation may not<br />

demonstrate the monoclonal proteins. When amyloidosis is suspected, initial laboratory testing should<br />

include serum immun<strong>of</strong>ixation electrophoresis and measurement <strong>of</strong> serum free light chains to increase<br />

test sensitivity for LCDD.<br />

MDPV intoxication usually manifests with a sympathomimetic toxidrome and psychological<br />

disturbances. Possible interaction with other psychoactive medication leading to serotonin syndromelike<br />

picture is a possibility. Rhabdomyolysis is also frequently seen Detection: currently undetectable via<br />

routine drug screen, detectable through GC-MS screens available via specialized<br />

laboratories. Treatment: Based on physician experiences and MoA <strong>of</strong> the drug, the following<br />

management is recommended - benzodiazepines to control sympathetic activity and psychomotor<br />

agitation avoid beta-blockers even at low doses to avoid unopposed alpha-adrenergic effects consider<br />

treatment with haloperidol / ziprasidone for treatment refractory to lorazepam involve toxicology<br />

Azathioprine Hypersensitivity with Acute Generalized Exanthematous Pustulosis (AGEP) Mimics Septic<br />

Shock<br />

Vasanth Kainkaryam, MD Aimee Leonard, MD<br />

INTRODUCTION: Acute generalized exanthematous pustulosis (AGEP) is a rare type IV drug<br />

hypersensitivity reaction commonly associated with antibiotics such as beta-lactams and macrolides,<br />

and less commonly with other drugs such as calcium channel blockers, vancomycin, and azathioprine. In<br />

this case, azathioprine-induced AGEP was associated with unusually severe hemodynamic instability,<br />

masquerading as septic shock.<br />

CASE PRESENTATION: A 58 year old obese female with P-ANCA pulmonary-renal vasculitis was<br />

admitted with presumed septic shock. Her medications included azathioprine, which was started 4-5<br />

days prior to admission, and prednisone. She initially presented to an outside hospital a two day history<br />

<strong>of</strong> malaise, decreased oral intake and urine output, orthostatic BP changes, fecal incontinence and a<br />

rash involving her trunk and extremities. Upon transfer to our hospital, she was severely hypotensive,<br />

with poor response to fluids, and was started on norepinephrine and transferred to the ICU.<br />

She was felt to be in septic shock given her immunocompromised status, hemodynamic instability,<br />

urinalysis concerning for urosepsis, transaminitis, and CXR concerning for possible pneumonia. An<br />

extensive workup was performed, and she was empirically treated with vancomycin and meropenem;<br />

acyclovir was added to cover for suspected disseminated varicella. Her shock-like symptoms and renal<br />

function acutely worsened and she eventually required two vasopressors.<br />

Her skin eruption progressed during her hospitalization and was characterized by monomorphous<br />

micropustules on an erythematous base. Dermatology was consulted and a punch biopsy showed<br />

intracorneal and subcorneal pustules, with the dermis containing superficial perivascular infiltration <strong>of</strong><br />

lymphocytes, eosinophils and neutrophils consistent with AGEP. The remainder <strong>of</strong> her workup including<br />

blood and urine cultures, viral cultures and DFA, lumbar puncture and bronchoscopy with respiratory<br />

DFA was negative. Given the skin biopsy findings <strong>of</strong> AGEP and the negative sepsis workup, her<br />

presentation was felt to reflect a severe life-threatening hypersensitivity reaction to azathioprine. Her<br />

broad spectrum antibiotic coverage was discontinued and she had a full recovery <strong>of</strong>f the <strong>of</strong>fending drug.<br />

DISCUSSION: AGEP is a rare hypersensitivity reaction, characterized by non-follicular sterile pustular<br />

lesions with an erythematous and edematous base, <strong>of</strong>ten presenting with pyrexia and neutrophilic<br />

leukocytosis. Reported incidence is 1-5 per million per year. Commonly reported agents associated<br />

with AGEP include antibiotics (particularly beta-lactams, macrolides, and vancomycin), viral infections,<br />

and mercury. The development <strong>of</strong> symptoms is usually acute, within 2-5 days <strong>of</strong> exposure with<br />

spontaneous resolution in 1-2 weeks. A mild transaminitis and acute kidney injury may also be<br />

present. While AGEP can resemble sepsis as has been reported with a case <strong>of</strong> ceftriaxone, severe<br />

hemodynamic derangement appears rare. In this case, azathioprine-induced AGEP was easily<br />

misdiagnosed initially as septic shock. Given the self-limiting nature <strong>of</strong> the disease, discontinuation <strong>of</strong><br />

the <strong>of</strong>fending agent and hemodynamic support are the main goals <strong>of</strong> care, with no clear role for<br />

steroids. Increased awareness <strong>of</strong> this condition is crucial for physicians given the associations with many<br />

medications, and potential for significant hemodynamic compromise.<br />

An Unusual and Curable Pancreatic Malignant Mass<br />

Zhongzhen Li, MD, Nadiya Vasdani BSc, Eddy Castillo MD. Dept. <strong>of</strong> Medicine, St. Vincent’s Medical<br />

Center, Bridgeport, CT<br />

INTRODUCTION: Primary pancreatic lymphoma (PPL) is a rare disease, accounting for only 1% <strong>of</strong><br />

extranodal lymphomas and 0.5% <strong>of</strong> all pancreatic masses. Differentiating PPL from the more common<br />

adnocarcinoma is difficult and important since the treatment and prognosis differ considerably.<br />

CASE PRESENTATION: A 43-year-old man presented with one-week duration <strong>of</strong> RUQ abdominal pain,<br />

nausea, weight loss and an epigastric mass. He had presented six month earlier with similar symptoms<br />

without weight loss or mass, all <strong>of</strong> which resolved after esomeprazole treatment. Physical examination<br />

revealed epigastric tenderness and a 6cm×3cm epigastric mass without peripheral lymphadenopathy or<br />

hepatosplenomegaly. Laboratory data showed normal CBC, serum transaminase and CA19-9 level;<br />

elevated amylase <strong>of</strong> 297, lipase <strong>of</strong> 264. CT scan <strong>of</strong> the abdomen showed a 14.3cm pancreatic head mass<br />

that obliterated fat planes between the stomach, duodenum and colon with mass effect on the IVC;<br />

scattered enlarged mesenteric and retroperitoneal lymph nodes. Endoscopic ultrasound (EUS) revealed<br />

a pancreatic head lesion causing extrinsic compression <strong>of</strong> the duodenum with ulceration. EUS guided<br />

fine needle aspiration (FNA) <strong>of</strong> the mass and duodenal mucosa revealed large atypical lymphoid cells<br />

positive for pan B-cells markers: CD20 and PAX5 with co-express <strong>of</strong> CD10, BCL-2, BCL-6 on<br />

immunohistochemstry staining. Flow cytometry analysis also demonstrates a monoclonal Kappa CD10<br />

positive large B-cell population. Bone marrow biopsy was normal. The above findings were indicative a<br />

diagnosis <strong>of</strong> PPL. Repeated CT 1-month after R-CHOP chemotherapy (Rituxan, Cyclophosphamide,<br />

Hydroxydaunorubicin, Oncovin and Prednisone) showed resolution <strong>of</strong> the mass with only hazy residual<br />

infiltration <strong>of</strong> the fat in the region anterior to the pancreatic head.<br />

DISCUSSION: PPL shows a slight male predominance and is usually seen in the 5 th or 6 th decade <strong>of</strong> life.<br />

Its vague symptoms and the most common location being in the pancreatic head make it difficult to<br />

differentiate PPL from the more common pancreatic adenocarcinoma without biopsy. Behrns' diagnostic<br />

criteria for PPL includes: no lymph node enlargement <strong>of</strong> superficial or mediastinal lymph nodes; a<br />

normal leukocyte count in the peripheral blood; main mass in the pancreas with lymph nodal<br />

involvement confined to the peripancreatic region, no hepatic or splenic involvement. This case<br />

highlights several important points. A large pancreatic mass without significant dilatation <strong>of</strong> the main<br />

pancreatic duct, invasion to the large vessels and obstructive jaundice and normal CA19-9 suggest a<br />

diagnosis <strong>of</strong> PPL over adenocarcinoma. EUS-FNA is a reliable and cost-effective method for pancreatic<br />

mass sampling. We successfully diagnosed the patient with EUS-FNA biopsy which avoids him from<br />

invasive diagnosis and therapy. Chemotherapy is the treatment <strong>of</strong> choice for PPL.<br />

A Case Of May-thurner Syndrome Associated With Phlegmasia Cerulea Dolens.<br />

Muhammad Adnan Sohail, MBBS Last author: David Roer, MD<br />

INTRODUCTION: Phlegmasia alba dolens is a spectrum <strong>of</strong> disease related to Deep venous thrombosis.<br />

It is a sudden onset <strong>of</strong> occlusion <strong>of</strong> deep venous system. The leg turns edematous and white (alba). As<br />

the superficial venous supply occludes, it affects the arterial flow and called plegmasia cerulea dolens.<br />

May-Thurner syndrome is a rare condition in which blood clots occur in the ili<strong>of</strong>emoral vein due to<br />

compression <strong>of</strong> the common venous outflow tract <strong>of</strong> the left lower extremity.<br />

CASE PRESENTATION: A 37-year-old Woman with a past medical history <strong>of</strong> depression, anxiety and<br />

migraine, who presented to emergency complaining <strong>of</strong> severe left leg pain and swelling which is sudden<br />

in onset. Pain is 10/10, worse with walking extends from calf and to distal leg. She was hemodynamically<br />

stable. Her left extremity was pale, white, swollen and dorsalis pedis pulse was diminished. Her<br />

laboratory data at admission showed lactic acid <strong>of</strong> 8, D-dimer <strong>of</strong> 4300 with normal hematology and<br />

metabolic pr<strong>of</strong>ile. Her US <strong>of</strong> lower extremity showed occlusive deep venous thrombosis extending from<br />

the left external iliac vein into the left popliteal vein. Venography showed a cast <strong>of</strong> thrombus filling in<br />

the left deep system from the common femoral vein to the mid popliteal vein. Diffuse left iliac vein<br />

stricture likely the etiology <strong>of</strong> the patient's DVT and consistent with May-Thurner syndrome. Pt has signs<br />

<strong>of</strong> left leg ischemia. An immediate thrombectomy was performed with a stent placement. CT chest did<br />

not show PE and CT abd/pelvis did not reveal any mass. Coagulation pr<strong>of</strong>ile did not show any<br />

abnormality and factor V and antithrombin 3 mutation was negative. Pts left leg pain immediately got<br />

better after thrombectomy with stenting and her pulse were full and color skin turned red. Pt was<br />

started on anticoagulation and discharged on warfarin.<br />

DISCUSSION: This is the rare presentation <strong>of</strong> deep venous thrombosis, which occluded venous system<br />

to the extent that it caused obstruction <strong>of</strong> blood supply to lower limb. Fabricus Hildanus first described<br />

this entity in the 16th century. Precipitating factors include malignancy, femoral vein catheterization,<br />

heparin-induced thrombocytopenia, antiphospholipid antibody syndrome. In May-Thurner syndrome,<br />

there is compression <strong>of</strong> the left common iliac vein by the overlying right common iliac artery. It occurs<br />

only in left leg. This is the first case <strong>of</strong> May-Thurner syndrome causing plegmasia cerulea dolens. Prompt<br />

diagnosis and treatment initiation are paramount in order to prevent progression to venous gangrene<br />

and the need for amputation and possible death <strong>of</strong> the patient who presents with this condition.<br />

SUGAR (Sulfonylurea Use Gone AwRy)<br />

Jennifer A Hurd, MD-Associate; Vinay Maheshwari M.D., Christiana Care Health Systems.<br />

INTRODUCTION: CASE PRESENTATION: A 45 year-old man with a history <strong>of</strong> diabetes mellitus, endstage<br />

renal disease on hemodialysis, and liver disease presented to the emergency department<br />

complaining <strong>of</strong> sweats, lightheadedness, and episodes <strong>of</strong> lethargy with slurred speech. His serum<br />

glucose was discovered to only be 20mg/dl. He was immediately administered multiple ampules <strong>of</strong> 50%<br />

dextrose (D50) solution and initiated on dextrose 5% continuous infusion. Repeat glucose testing was ><br />

100mg/dl, but subsequent testing revealed repeated severe hypoglycemia requiring treatment. The<br />

patient’s course then entered a cycle <strong>of</strong> responding to glucose- containing fluid followed by a severe<br />

drop in blood sugar 1 hour later. Supplementation with 10% dextrose fluid was then initiated without<br />

overall improvement in the dramatic fluctuations in blood sugar measurements.<br />

After a number <strong>of</strong> hours, the patient finally admitted to ingestion <strong>of</strong> 8mg <strong>of</strong> glimepiride to treat a<br />

random home blood glucose measurement <strong>of</strong> >400mg/dl. Once the etiology was discovered,<br />

formulation <strong>of</strong> a more effective treatment plan was required. This was more imperative given his poor<br />

response to glucose supplementation, as well as the prolonged half- life <strong>of</strong> glimepiride in the setting <strong>of</strong><br />

renal failure. He received a bolus dose <strong>of</strong> octreotide followed by a continuous infusion at 25mcg/hr. His<br />

blood glucose values immediately began to improve and no further hypoglycemia was observed.<br />

DISCUSSION: This case highlights the limitation <strong>of</strong> dextrose as monotherapy in sulfonylurea<br />

overdose. The mechanism <strong>of</strong> action <strong>of</strong> sulfonylureas lies in their effects on the potassium channels <strong>of</strong><br />

the pancreatic beta cell membranes resulting in increased insulin release. As a class, they are hepatically<br />

metabolized and some, including glimepiride, have renally excreted active metabolites. Glucose<br />

administration is indicated overdose; however, glucose may also stimulate further insulin secretion<br />

resulting in persistent hypoglycemia. Multiple case reports exist in the literature regarding using<br />

ocreotide as an adjunctive therapy in sulfonylurea overdose. 1 Octreotide is a somatostatin analog<br />

whose proposed mechanism <strong>of</strong> action is via inhibition <strong>of</strong> the voltage-gated channels on pancreatic beta<br />

cells, causing a G protein-mediated decrease in calcium influx, which in turn decreases insulin<br />

secretion. 2 Doses can range between 50 to 150 mcg intramuscularly or subcutaneously every 6 hours or<br />

be delivered by continuous infusions. Following adjunctive therapy with octreotide, our patient’s cyclic<br />

hypoglycemia resolved, allowing transfer to a lower level <strong>of</strong> care and a shorter hospital stay. Octreotide<br />

therapy should be considered in patients who present with sulfonylurea overdose, particularly if<br />

refractory to glucose administration.<br />

Health System, Newark, DE<br />

INTRODUCTION: Fatigue is common complaint. Routine laboratory investigations are rarely <strong>of</strong> help.<br />

This case illustrates that in a young patient with a clear change in energy level, targeted laboratory tests<br />

can be diagnostic <strong>of</strong> several conditions warranting treatment.<br />

CASE PRESENTATION: A 17 year-old Hispanic female with history <strong>of</strong> vitiligo presented with gradually<br />

worsening fatigue and sleepiness, before which she had been quite active. Her remaining past medical<br />

history was notable only for allergic rhinitis. Menses began at age 12 and were reportedly normal.<br />

Physical examination was normal except for vitiligo. Laboratories studies revealed normal basic<br />

metabolic panel, CBC, liver functions, vitamin B12, and peripheral blood smear. Thyroid stimulating<br />

hormone (TSH) was markedly low at

Chapter Winning Abstract A Case <strong>of</strong> Massive Splenomegaly<br />

Lara Paraskos, MD<br />

INTRODUCTION: Gaucher’s Disease is a lysosomal storage disease where a deficiency in the<br />

glucocerebrosidase enzyme causes glucocerebroside to accumulate in the bone marrow, liver, spleen<br />

and lungs. Common presenting symptoms include anemia, thrombocytopenia, osteopenia, growth<br />

retardation, and hepatosplenomegaly. Type 1, the nonneuronopathic form, more common in Ashkenazi<br />

Jewish heritage with a disease frequency <strong>of</strong> 1 per 855. Types 2 and 3 are the neuronopathic forms that<br />

involve the CNS. Family and ethnic history is vital in considering the diagnosis which is confirmed with<br />

bone marrow or liver biopsy showing macrophages with the classic abundant crinkled tissue-paper<br />

cytoplasm as in this case.<br />

CASE PRESENTATION:: Obtaining an adequate family history with focus on ethnic background plays an<br />

important role in the recognition <strong>of</strong> genetic diseases. Although Gaucher’s disease is an uncommon<br />

condition in an adult population; including this type <strong>of</strong> conditions in the differential diagnosis may<br />

improve early diagnosis, adequate treatment and overall prognosis. Early recognition in this patient may<br />

have prevented unnecessary and potentially harmful workup.<br />

“i Am Different From The Rest!” An Interest Case Of Hormonal Control.<br />

Ricardo Correa, MD, Melany Castillo, Ana Sandoval, Alejandro Ayala<br />

INTRODUCTION: Kallmann's syndrome is characterized by hypogonadotropic hypogonadism and one<br />

or more non-gonadal congenital abnormality, including anosmia, red-green color blindness, midline<br />

facial abnormalities such as cleft palate, urogenital tract abnormalities, synkinesis (mirror movements)<br />

and neurosensory hearing loss.<br />

CASE PRESENTATION: We present a 28-year-old gentleman who was first diagnosed with testosterone<br />

deficiency approximately at 12 years old in Cuba. He was treated with "a cycle <strong>of</strong> testosterone" but then<br />

it was discontinued by his doctors. When he was 17, he was told that one <strong>of</strong> his testicles had not<br />

descended into the scrotum while being examined for a military service. He then immigrated to United<br />

States in 2010, where his PCP noted that he was hypogonadic and then referred to the endocrinology<br />

clinic.<br />

At his first visit, he denies any history <strong>of</strong> olfactory problems, although, upon further questioning, he<br />

clearly states that he has difficulty smelling different substances, which was clear during physical<br />

examination where he was unable to distinguish the smell <strong>of</strong> c<strong>of</strong>fee, alcohol, perfume or chocolate. He<br />

also mentioned that he has a 21 and a 4 year-old nephew that also appeared to be hypogonadic and<br />

have cryptorchidism and synkinesis.<br />

The patient had not developed secondary sexual male characteristics except for the mild presence <strong>of</strong><br />

terminal hair in the pubic area and he had a fine voice with eunuchoid habitus. Imaging studies as well<br />

as test were unremarkable, except for low serum levels <strong>of</strong> FSH, LH, HCG, total testosterone and free<br />

testosterone indicating severe hypogonadism. The patient was stared in low dose <strong>of</strong> testosterone, with<br />

further counseling <strong>of</strong> fertility.<br />

DISCUSSION: More recently, genetic testing has provided a more detailed understanding <strong>of</strong> the<br />

disease. Studies <strong>of</strong> patients with Kallmann's syndrome have demonstrated mutations <strong>of</strong> several genes<br />

that encode cell surface adhesion molecules or their receptors required for the migration <strong>of</strong> GnRHsecreting<br />

neurons from the olfactory placode into the brain and then into the hypothalamus. These<br />

genes include KAL1 , fibroblast growth factor receptor 1 (also called KAL2) , prokineticin-2 (PROK2) and<br />

its receptor (PROKR-2).<br />

These mutations account for less than 50% <strong>of</strong> the cases. Therefore, identifying new patients with the<br />

disease that do not have previously described mutations may shed a new light into the pathophysiology<br />

<strong>of</strong> this rare disorder and bring upon further understanding <strong>of</strong> the mechanism that govern gonadal<br />

function.<br />

Parasite In The Brain: An Unusual Case Of Severe Malaria<br />

Ricardo Correa, MD, Ashley Britel, Hoang Minh, Libin Wang<br />

INTRODUCTION: Cerebral malaria is an encephalopathy that presents with impaired consciousness,<br />

delirium, and/or seizures; focal neurologic signs are unusual. The onset may be gradual or sudden<br />

following a convulsion. Although the pattern <strong>of</strong> cerebral malaria in children has been extensively<br />

reported, relatively little is known <strong>of</strong> the clinical features <strong>of</strong> cerebral malaria in adults.<br />

CASE PRESENTATION: 61 year old Haitian male who came directly from Miami International Airport<br />

presented with 15 day history <strong>of</strong> subjective fever, weakness, fatigue, shortness <strong>of</strong> breath, palpitation,<br />

nausea, cough with yellow sputum and chest discomfort.<br />

He had a past medical history <strong>of</strong> hypertension, diabetes mellitus, hyperlipidemia, diastolic heart failure<br />

with an EF <strong>of</strong> 40% and breast cancer in 2002 (which was treated with mastectomy, chemotherapy until<br />

2005 and Femara until 2010. Also, he was hospitalized with pneumonia in March 2010 treated with<br />

ceftriaxone and azithromycin; these two medications plus Femara resulted in acute liver failure<br />

requiring a month’s stay in the intensive care unit.<br />

On the physical exam, the patient was in mild distress, afebrile but tachypneic with rhales bilaterally; all<br />

other systems were within normal limits.<br />

On hospital day 1, the patient became febrile, thus´ pancultures were drawn and was started on<br />

lev<strong>of</strong>loxacin for the possibility <strong>of</strong> a community acquire pneumonia. In addition, a peripheral blood smear<br />

and dengue serology were ordered because <strong>of</strong> the possibility <strong>of</strong> malaria or dengue (patient had recent<br />

travel to Haiti) and the presence <strong>of</strong> dark urine. On hospital day 3, the patient developed altered mental<br />

status. The Glasgow scale <strong>of</strong> the patient went from 15/15 to 7-8/15 and he was transfered to the MICU.<br />

Dengue serology came back negative but the thin and thick smear for malaria was positive and reported<br />

P.falciparum with 2% <strong>of</strong> parasitemia. He was treated with artesumate and then switched to doxycicline<br />

for 7 days. The patient recovered and was discharged home without any sequelae or complications from<br />

his illness.<br />

DISCUSSION: The criteria for making the diagnosis <strong>of</strong> cerebral malaria include: Glasgow coma score less<br />

than 11 in adults, P. falciparum parasitemia and no other identifiable cause <strong>of</strong> coma (e.g.,<br />

hypoglycemia, meningitis, or a post-ictal state). The most common symptoms at presentation are fever,<br />

general malaise, cough, myalgia, vomiting, headache, hepatomegaly, and splenomegaly. The definitively<br />

treatment is based on two major classes <strong>of</strong> drugs available in parenteral form: the cinchona alkaloids<br />

and the artemisinin derivatives.<br />

The lesson learned from this case is that one has to keep in mind the diagnosis <strong>of</strong> cerebral malaria if a<br />

patient has had recent travel to an endemic area, despite the absence <strong>of</strong> typical symptoms <strong>of</strong> malaria as<br />

in our unusual case. Early detection leads to early treatment which is critical in preventing progression<br />

to severe, life threatening disease<br />

I Smell A Rat: A Case Report And Literature Review Of Paradoxical Thrombosis And Hemophilia In A<br />

Patient With Brodifacoum Toxicity.<br />

David Franco, MD George Everett, M.D., F.A.C.P. Manoucher Manoucheri M.D., F.A.C.P.<br />

INTRODUCTION: Brodifacoum poisoning occurs as a result <strong>of</strong> ingestion <strong>of</strong> rodenticide compounds. It<br />

acts as a superwarfarin, inhibiting an enzyme vital for vitamin K recycling, vitamin K epoxide reductase,<br />

in an irreversible fashion much like warfarin but with a much longer half life.<br />

CASE PRESENTATION: A 48 year-old female patient reported four days <strong>of</strong> mild dyspnea, dry cough,<br />

bilateral popliteal fossae pain, and diffuse upper abdominal pain. Her past medical history was<br />

significant for an unspecified psychiatric disorder and pain seeking behavior. She had no history <strong>of</strong> liver<br />

disease, alcohol or illicit substance abuse. Initial physical exam was remarkable only for mildly pale<br />

conjunctivae and mild tenderness <strong>of</strong> the left side <strong>of</strong> the abdomen and in the left popliteal fossa. CBC was<br />

normal. Complete metabolic panel (CMP) was only positive for an aspartate aminotransferase <strong>of</strong> 56.<br />

Prothrombin time (PT) was above 100 seconds, partial thromboplastin (PTT) time was above 200<br />

seconds and international normalized ratio (INR) was reported as above 12.0. Urinalysis was positive for<br />

2+ hematuria and mild leukocyturia. Venous Doppler ultrasound <strong>of</strong> lower extremities demonstrated a<br />

thrombus in the left popliteal vein. CT scan <strong>of</strong> the abdomen demonstrated terminal ileum thickening<br />

probably related to transmural hematoma and fecal occult blood test was positive. A full anticoagulant<br />

work up showed critical reduction <strong>of</strong> vitamin K dependant factors II, VII, IX and X. PT and PTT corrected<br />

with mixing studies proving factor deficiency as the cause <strong>of</strong> the coagulopathy. Lupus anticoagulant<br />

studies were negative. Given these findings, vitamin K antagonist toxicity was suspected and confirmed<br />

with an anticoagulant poison panel positive for Brodifacoum, a commonly encountered substance in<br />

rodenticides. The patient was hospitalized and successfully treated with fresh frozen plasma,<br />

cryoprecipitate and parenteral vitamin K supplementation as adjunctive therapy.<br />

DISCUSSION: We postulate that the cause <strong>of</strong> the thrombotic phenomenae was related to the rapid<br />

depletion <strong>of</strong> proteins C and S within the initial period <strong>of</strong> toxicity and therefore a transient thrombophilia<br />

that was followed by a tendency for hemorrhage. In conclusion, paradoxical thrombosis and hemophilia<br />

should raise the suspicion for superwarfarin toxicity in the appropriate clinical setting. Further studies<br />

are required to define the optimal management <strong>of</strong> these patients.<br />

Massive Enoxaparin Overdose: What Are the Therapeutic Options?<br />

Morganna Freeman, DO, PGY3 (Internal Medicine Residency Program, Shands at the University <strong>of</strong><br />

Florida) and Marc Zumberg, MD, FACP (Division <strong>of</strong> Hematology, Department <strong>of</strong> Internal Medicine at the<br />

University <strong>of</strong> Florida)<br />

INTRODUCTION:Enoxaparin (low-molecular weight heparin, LMWH) has seen increasing use as both a<br />

therapeutic and prophylactic anticoagulant, however its activity against thrombin and activated Factor X<br />

makes its reversibility problematic, as opposed to heparin or warfarin. As a result, management <strong>of</strong><br />

LMWH overdose presents a challenge for internists and hematologists alike. Here, we present the<br />

diagnostic and therapeutic dilemmas presented with a massive intentional overdose <strong>of</strong> enoxaparin.<br />

CASE PRESENTATION: A 34 year old female with a history <strong>of</strong> bipolar disorder was admitted to our<br />

intensive care unit after being found at home following a suicide attempt; empty bottles <strong>of</strong> Xanax and<br />

Fioricet were found at the bedside. She also had a history <strong>of</strong> pulmonary embolism linked to<br />

heterozygous Factor V Leiden mutation and had been prescribed enoxaparin 80mg subcutaneously BID.<br />

She had recently filled her prescription, and twenty empty enoxaparin syringes were also found at the<br />

scene. She was intubated for unresponsiveness and brought to our hospital for further treatment.<br />

On initial exam the patient had wrist lacerations without active bleeding and multiple abdominal<br />

ecchymoses at the injection sites. Initial labs showed acetaminophen level <strong>of</strong> 16, INR <strong>of</strong> 1.3, protime <strong>of</strong><br />

16.4, PTT <strong>of</strong> 98, LWMH level <strong>of</strong> 8 (normal range 0.8-1.2) and normal liver function tests. Urine drug<br />

screen was positive for benzodiazepines and barbiturates. She was treated with n-acetylcysteine for<br />

acetaminophen overdose, and Hematology consultants recommended serial monitoring <strong>of</strong> LMWH level,<br />

complete blood counts (CBCs) and neuro examinations. Literature search yielded no proven treatment<br />

for such a large overdose <strong>of</strong> enoxaparin, with protamine reportedly only marginally effective. Factor VII<br />

was considered, but given its prothrombotic effect and her history <strong>of</strong> PE it was decided to delay this<br />

treatment until evidence <strong>of</strong> bleeding manifested.<br />

Twenty four hours into admission, she became hypotensive and had a Hematocrit drop from 39% to<br />

23%. CT <strong>of</strong> the abdomen showed large, bilateral retroperitoneal hematomas with active bleeding near<br />

the common femoral artery. Vascular Surgery was consulted but no surgical intervention was staged.<br />

She received 6 units <strong>of</strong> packed red blood cells, 50mg <strong>of</strong> protamine, and three doses <strong>of</strong> Factor VII.<br />

Subsequent to this treatment, no further bleeding episodes occurred and she was successfully<br />

extubated twenty four hours later. It took sixty hours for her LMWH level to normalize.<br />

DISCUSSION: The management <strong>of</strong> LMWH overdose is not well-documented in the literature; there is no<br />

effective reversal agent, and hematology sources cite the success <strong>of</strong> protamine as less than 60 percent.<br />

Currently no treatment guidelines exist, and unfortunately clinicians must rely on a “watch and wait”<br />

approach to therapy as bleeding complications vary. With the increasing use <strong>of</strong> LMWH, however,<br />

clinicians must be mindful <strong>of</strong> overdose, as the lack <strong>of</strong> a proven reversal agent continues to pose<br />

management challenges.<br />

A Devastating Birth Mark<br />

Shenoda Gadalla, MD Second Author: Joao Braghiroli, MD Third Author: Venkat Kalindindi, MD<br />

INTRODUCTION:Congenital spina bifida oculta is associated with distortion <strong>of</strong> the spinal cord, the<br />

spinal nerve roots or both. The effect <strong>of</strong> the anomalies is evident as neurological abnormalities <strong>of</strong> the<br />

lower limbs and neuropathic bladder dysfunction. Adult patients with spina bifida may present with<br />

urinary symptoms as the sole initial complaint and lack obvious neurological abnormalities, but usually a<br />

tuft <strong>of</strong> hair is evident on the lower back. Renal scaring and renal failure are secondary to neurogenic<br />

bladder in patients with spina bifida.<br />

CASE PRESENTATION: This is a 30-year-old male originally from British Guyana without significant<br />

medical history who presented with a one month history <strong>of</strong> worsening bilateral lower extremity edema<br />

and confusion. He reported incontinence during childhood that resolved by the age <strong>of</strong> 13 and he<br />

recently noted a decrease in his urine output. He denied dysuria, hematuria, flank pain, fever, chills,<br />

nausea or vomiting. He also denied recent sore throat, skin infection or medication usage.<br />

On physical examination, vitals were remarkable for an elevated blood pressure <strong>of</strong> 208/129. Skin exam<br />

was consistent with the presence <strong>of</strong> a tuft <strong>of</strong> hair on the lower back which the patient identified as a<br />

birthmark. Lower extremities had 2+ non-pitting edema and uremic frost between his toes bilaterally.<br />

The patient was somnolent, but oriented to place and person, without focal neurological deficit.<br />

Labs showed hemoglobin 7.2, platelet 113, potassium <strong>of</strong> 5.3, bicarbonate 14, albumin 3.9, BNP 6429,<br />

BUN >140, creatinine > 20, amylase 829 , lipase 12620.<br />

A computerized tomography <strong>of</strong> the abdomen and pelvis without contrast revealed an edematous<br />

pancreas with stranding <strong>of</strong> the peripancreatic fat and atrophic kidneys. The renal ultrasound showed a<br />

severely atrophic left kidney and was unable to visualize the right kidney secondary to advanced<br />

atrophy. Voiding cystourethrogram showed large postvoid urinary bladder residual and mildly<br />

trabeculated urinary bladder consistent with neurogenic bladder. The patient was admitted to intensive<br />

care unit and hemodialysis was initiated. Considering the diagnosis <strong>of</strong> neurogenic bladder, the patient is<br />

ultimately a poor candidate for a renal transplant.<br />

DISCUSSION: Renal damage and renal failure are among the most severe complications <strong>of</strong> spina bifida.<br />

An early diagnosis and comprehensive treatment strategy should be applied in order to result in minimal<br />

renal scaring. The majority <strong>of</strong> patients are able to control their urinary sphincter by the time they start<br />

elementary school. To obtain such results, it is mandatory to treat detrusor overactivity from birth<br />

onward since upper urinary tract changes predominantly start in the first months <strong>of</strong> life. Patients with<br />

spina bifida should be treated from birth by sterile intermittent catheterization and pharmacological<br />

suppression <strong>of</strong> detrusor overactivity to prevent renal failure secondary to renal scaring.<br />

Stay Hydrated” or Danger <strong>of</strong> Social Polydipsia<br />

Maroz Natallia, Ejaz Ahsan Division <strong>of</strong> Nephrology, Hypertension and Renal Transplantation University <strong>of</strong><br />

Florida, Gainesville.<br />

INTRODUCTION:Popularizing <strong>of</strong> health maintenance related habits via the social media by nonmedical<br />

pr<strong>of</strong>essionals can lead to misuse <strong>of</strong> potentially beneficial recommendations. Frequently used "Stay<br />

hydrated" message, encouraging people to consume fluids in excess to their natural thirst, can lead to<br />

several water-balance abnormalities.<br />

CASE PRESENTATION: 53 year old woman was referred to nephrology clinic for the second opinion on<br />

persistent hydronephrosis. She had a history <strong>of</strong> asthma, hysterectomy and recent diagnosis <strong>of</strong> diabetes<br />

mellitus (DM) type II. Her only medication was Sitagliptan 50 mg daily for the last 2 years and family<br />

history was significant for DM type 2.<br />

12 months prior to her presentation patient experienced mild bilateral flank pain. As a part <strong>of</strong> her<br />

evaluation computed tomography (CT) <strong>of</strong> the abdomen was completed and revealed presence <strong>of</strong><br />

moderate bilateral hydronephrosis and hydroureters. Her renal function was normal. Lack <strong>of</strong> health<br />

insurance delayed urological evaluation for 6 months. Repeated CT and intravenous pyelogram<br />

confirmed persistent moderate hydronephrosis on the right, and mild on the left. The cystoscopy was<br />

unremarkable.<br />

Patient underwent placement <strong>of</strong> right ureteral stent. Unfortunately, she experienced post-procedural<br />

pain and no improvement in hydronephrosis was noted on the repeated CT scan in 2 months. Ureteral<br />

stent was removed and patient was referred to the gynecologist. She underwent exploratory<br />

laparoscopy with lysis <strong>of</strong> adhesions and right oophorectomy. One month later CT was repeated and<br />

revealed unchanged degree <strong>of</strong> bilateral hydronephrosis. At that point, patient was referred to the<br />

tertiary center for further management.<br />

Upon review <strong>of</strong> systems patient reported to drink 4.5-5.5 liters <strong>of</strong> fluids daily for the last 3 years as “All<br />

my friends do so to stay healthy”. Her physical examination and laboratory data were unremarkable.<br />

Her HBA1C was 6.3, serum sodium 139 mg/dL and urine specific gravity 1.019.<br />

Patient was suspected to have non-obstructive fullness in urine excretory system, due to mismatch <strong>of</strong> its<br />

capacity to excessive production <strong>of</strong> urine. She was advised to decrease intake <strong>of</strong> fluids to no more than 2<br />

liters per day and return for follow-up in 6 weeks.<br />

The repeated kidney ultrasound at the time <strong>of</strong> follow-up revealed normal sized kidneys bilaterally and<br />

complete resolution <strong>of</strong> hydronephrosis. Patient was discharged from the nephrology clinic with<br />

recommendations to drink by thirst.<br />

DISCUSSION: Although non-obstructive hydronephrosis due to polydipsia was recognized at least since<br />

Oslers's description <strong>of</strong> several cases, majority <strong>of</strong> physicians are not well aware about this condition. This<br />

unfortunately can lead to unnecessary invasive and morbid medical interventions and significant healthrelated<br />

cost. Considering the sequel <strong>of</strong> exaggerated social habits promoted by modern media is<br />

important part <strong>of</strong> practicing medicine in 21st century.<br />

Medical decision: “Do no harm” or “better safe than sorry”? Mycophenolate M<strong>of</strong>etil used in a lupus<br />

patient with diffuse alveolar hemorrhage.<br />

Laurie Ann Ramrattan, MD GS Kaeley, MBBS, MRCP, C Pappa, MD.<br />

INTRODUCTION: Five million people worldwide suffer from Systemic Lupus Erythematosus (SLE), a<br />

complex disease with potentially fatal complications. Early mortality in SLE has been improved with the<br />

use <strong>of</strong> cytotoxic drugs. On the other hand, infections attributed predominantly to immunosuppressant<br />

medications account for approximately 25% <strong>of</strong> all deaths. Therefore judicious use <strong>of</strong> medications that<br />

balances the risks and benefits <strong>of</strong> an aggressive treatment is needed.<br />

CASE PRESENTATION: A 26-year-old female presented with a two-week history <strong>of</strong> fever and dyspnea.<br />

She also reported arthralgias, photosensitive rash, hair loss and Raynaud’s phenomenon <strong>of</strong> the same<br />

duration. On examination she was found to be febrile and tachycardic. Significant labs showed:<br />

hemoglobin <strong>of</strong> 6.8 g/dl, white cell count <strong>of</strong> 2.2 x 10 9 /l and a creatinine <strong>of</strong> 0.77 mg/dl. Chest radiograph<br />

indicated reticulonodular opacifications involving the lower lung fields and CT chest revealed diffuse<br />

interstitial and parenchymal opacities. Bronchoscopy revealed bright red blood due to diffuse alveolar<br />

hemorrhage (DAH). Bronchoalveolar lavage cultures were negative. Her constellation <strong>of</strong> symptoms was<br />

suggestive <strong>of</strong> SLE which was confirmed by the positive serology: ANA >1:1280, elevated double stranded<br />

DNA >300 IU/ml, anti- Smith >8 AI, RNP>8 AI and anti Ro>8 AI. Complement levels were depressed (C3-<br />

26 and C4-5.1). Urinalysis was benign. ANCA, anti-GBM and antiphospholipid antibodies were negative.<br />

The patient was diagnosed with DAH secondary to SLE and daily intravenous 1 gram methylprednisolone<br />

was given for 3 days, followed by oral prednisone 60mg daily. Cyclophosphamide was initially<br />

considered as a steroid sparing treatment, however due to the rapid improvement <strong>of</strong> symptoms,<br />

mycophenolate m<strong>of</strong>etil (MMF) was felt to be a safer choice. Ten months later prednisone was<br />

successfully tapered to 5 mg daily and the patient remained asymptomatic on MMF without evidence <strong>of</strong><br />

recurrence <strong>of</strong> pulmonary hemorrhage.<br />

DISCUSSION: DAH is a rare and potentially catastrophic complication <strong>of</strong> SLE. It usually occurs in<br />

patients with a known history <strong>of</strong> SLE and active extrapulmonary disease. Early aggressive treatment with<br />

high dose corticosteroids and cyclophosphamide is considered to be the standard <strong>of</strong> care and has<br />

significantly decreased mortality. MMF in addition to steroids has not been used for induction therapy<br />

<strong>of</strong> DAH in SLE. MMF causes less morbidity and mortality when compared to cyclophosphamide. Our<br />

patient showed remarkable improvement even before MMF was initiated; however addition <strong>of</strong> a<br />

steroid-sparing agent was necessary to prevent a possible fatal recurrence <strong>of</strong> pulmonary hemorrhage.<br />

Our case is unique in that our patient presented with DAH as the first presenting symptom <strong>of</strong> lupus and<br />

that the induction <strong>of</strong> remission and maintenance was accomplished with less aggressive treatment.<br />

Diplopia: Not always a benign symptom<br />

Anusha Vallurupalli, MBBS Second Author: Roja Harish-Pondicherry, MD Faculty Author: Nam H Dang,<br />

MD, PHD<br />

INTRODUCTION: Diplopia, commonly known as double vision, is usually a result <strong>of</strong> impaired extra<br />

ocular muscle dysfunction. As an example, the sixth cranial nerve innervates lateral rectus muscle <strong>of</strong> the<br />

eye and aids in abduction; palsy <strong>of</strong> this nerve can result in impaired abduction <strong>of</strong> the affected eye and<br />

resultant diplopia.<br />

CASE PRESENTATION: A 42 year old Caucasian male with past medical history <strong>of</strong> chronic low back<br />

pain, and hypertension presented with a 4-day history <strong>of</strong> double vision. He noted diplopia when looking<br />

straight ahead which worsened when looking to the far right. He denied double vision when looking to<br />

the left or when covering either eye. Complete review <strong>of</strong> systems was negative aside from the diplopia<br />

and mild headaches. Physical examination was significant for partial lateral rectus palsy <strong>of</strong> the right eye<br />

with failure to abduct the eye when looking far right.<br />

Given his young age and absence <strong>of</strong> other neurologic symptoms, malignancy was suspected and workup<br />

was pursued. Chest X-ray revealed a paratracheal mass that was demonstrated on chest CT as<br />

conglomerate anterior mediastinal mass concerning for lymphoma. CT-guided biopsy <strong>of</strong> the mass was<br />

positive for Acute T-cell lymphoblastic lymphoma. MRI <strong>of</strong> the brain and CSF analysis were negative for<br />

CNS involvement. PET scan was positive for FGD- avid conglomerate anterior mediastinal mass, right<br />

supra-clavicular, and retro-crural lymph node and 1.6 cm pleural based nodule. Bone marrow biopsy<br />

was negative for lymphoma. He was initiated on Hyper-CVAD (Cytoxan, Adriamycin, Vincristine and<br />

Dexamethasone) alternating with high dose Methotrexate. He is receiving CNS prophylaxis with<br />

intrathecal methotrexate and Cytarabine. By the second cycle <strong>of</strong> chemotherapy he noted improvement<br />

in double vision, with improved sixth cranial nerve palsy on physical examination. Chest X-ray confirmed<br />

a decrease in the size <strong>of</strong> the mediastinal mass. At subsequent visits, the cranial nerve palsy had<br />

completely resolved with continued regression <strong>of</strong> the mediastinal mass.<br />

DISCUSSION: Isolated sixth cranial nerve palsy is usually seen in elderly population with increased<br />

incidence in 5 th decade <strong>of</strong> life. Microvascular occlusion <strong>of</strong> the arterioles supplying the nerve from<br />

diabetes or hypertension is the common cause. These palsies are usually acute in onset, present with<br />

complete palsy, and resolve in 2-3 months <strong>of</strong> treatment <strong>of</strong> the underlying condition. A higher index <strong>of</strong><br />

suspicion must be maintained in younger adults with isolated partial sixth cranial nerve palsy, as<br />

malignancy, infectious processes and autoimmune diseases such as myasthenia gravis, multiple<br />

sclerosis, sarcoidosis and giant cell arteritis may be identified. To our knowledge, this is the first<br />

description <strong>of</strong> isolated partial sixth nerve palsy associated with T lymphoblastic lymphoma without<br />

primary Central nervous system involvement.<br />

Chapter Winning Abstract - A Rare Case <strong>of</strong> an Inferior Vena Cava in a Young Woman<br />

Mary Nwoke, Mark Bradshaw, Justin Rafael, Balsam ElHammali, Chinedu Ivonye<br />

INTRODUCTION:Absence <strong>of</strong> inferior vena cava (IVC) is a rare congenital condition, present in less than<br />

0.5% <strong>of</strong> the population. This congenital abnormality tends to be more prevalent in men. Some<br />

individuals with this anomaly may be asymptomatic and diagnosed during routine imaging for other<br />

conditions. This anomaly may predispose individuals to venous thromboembolism (VTE). We present a<br />

rare case <strong>of</strong> absent IVC in a young woman who presented with VTE.<br />

CASE PRESENTATION: 28 year old woman with no significant past medical history who presented with<br />

pain and swelling <strong>of</strong> her left lower extremity. She reported recent travel history <strong>of</strong> about 4 hours<br />

duration, and she also gave history <strong>of</strong> oral contraception (OCP) use. She reported left lower extremity<br />

pain was preceded by shortness <strong>of</strong> breath which was exacerbated by exertion; she however denied<br />

pleuritic chest pain or shortness <strong>of</strong> breath at rest. Her family history was significant for mother with a<br />

history <strong>of</strong> two deep vein thrombosis (DVT).<br />

Physical examination was essentially benign except for significant swelling <strong>of</strong> her left leg and thigh.<br />

Doppler ultrasound <strong>of</strong> bilateral lower extremities was obtained which was significant for deep venous<br />

thrombosis extending from the left groin to the left popliteal vein. There was no evidence <strong>of</strong> DVT within<br />

the deep veins <strong>of</strong> the right lower extremity. Chemistry done was within normal limits; however D-dimer<br />

was elevated at 3762. This prompted evaluation for a pulmonary embolus; ventilation perfusion scan<br />

was completed which was negative. She was anticoagulated and achieved therapeutic INR prior to<br />

discharge.<br />

She presented to the hospital 15 days later with complaints <strong>of</strong> pleuritic chest pain; it was at this time<br />

CT/PE protocol done was negative for pulmonary embolus but incidental findings showed an elongated<br />

right, middle and posterior mediastinal mass with additional paravertebral s<strong>of</strong>t tissue at the T8 level.<br />

There were s<strong>of</strong>t tissue extensions through multiple bilateral lower thoracic neural foramina into the<br />

spinal canal with mass effect on the spinal cord. This was felt to be consistent with nerve cell tumor<br />

versus other tumor <strong>of</strong> unclear etiology and MRI was recommended. Patient subsequently obtained<br />

MRI/MRA/MRV chest/abdomen/pelvis which showed dilated azygos vein, hemiazygos vein and lumbar<br />

venous collaterals as well as dilated epidural venous plexus. The inferior vena cava was absent.<br />

DISCUSSION: Anomalies <strong>of</strong> the IVC are present in 0.3%-0.5% <strong>of</strong> healthy individuals. These anomalies<br />

include hypoplasia <strong>of</strong> the IVC, double IVC, left IVC, and the absence <strong>of</strong> IVC. Congenital absence <strong>of</strong> IVC has<br />

been reported mostly in men. This is one <strong>of</strong> the few cases in literature reported in a woman. Absence <strong>of</strong><br />

the IVC in any individual is a rare occurrence and usually an incidental finding on imaging. It has been<br />

confirmed as a critical risk factor for deep vein thrombosis in young patients because <strong>of</strong> resultant<br />

venous stasis. It is therefore recommended that young patients presenting with DVT, in the absence <strong>of</strong><br />

major recognized risk factors should be investigated for possible anomaly <strong>of</strong> the IVC.<br />

A Rare Case Of Atrial Myxoma In A Patient With Hypertrophic Cardiomyopathy<br />

Mahmoud Abdou, MD, Salim Hayek, MD, Byron R. Williams III, MD - Internal Medicine Residency<br />

Program and Division <strong>of</strong> Cardiology, Emory University, Atlanta, Georgia, USA<br />

INTRODUCTION: Atrial myxomas are the most common primary cardiac tumors. Patients with atrial<br />

myxomas typically present with obstructive, embolic or systemic symptoms. Asymptomatic presentation<br />

<strong>of</strong> atrial myxoma is very rare. Furthermore, the association <strong>of</strong> atrial myxoma with hypertrophic<br />

cardiomyopathy (HCM) has only been reported in three cases in the literature.<br />

CASE PRESENTATION: Here we report the case <strong>of</strong> a 71 year-old female with known HCM who was<br />

referred to cardiology clinic for placement <strong>of</strong> an automated implantable defibrillator as primary<br />

prevention <strong>of</strong> sudden cardiac death. An atrial myxoma was discovered incidentally on pre-procedural<br />

evaluation. She was asymptomatic, and her physical exam was only notable for a faint, grade 1/6 earlypeaking<br />

short systolic murmur at the left upper sternal border that did not change with position. Initial<br />

transthoracic echocardiogram showed asymmetric hypertrophy <strong>of</strong> the basal and mid anteroseptal wall.<br />

A saline contrast bubble study was positive; prompting a follow-up transesophageal echocardiogram<br />

which revealed what was confirmed in cardiac MRI as a 1.2 x 2.2 cm broad-based irregular mass in the<br />

left atrium arising from the interatrial septum near the foramen ovale. The patient underwent surgical<br />

excision <strong>of</strong> the left atrial mass and partial excision <strong>of</strong> the left atrial septum. Review <strong>of</strong> the histopathology<br />

confirmed the diagnosis <strong>of</strong> atrial myxoma. She continues to do well, with no evidence <strong>of</strong> recurrence.<br />

DISCUSSION: Cardiac tumors are infrequent clinical entities with prevalence ranging from 0.001% to<br />

0.030%. Approximately three-quarters <strong>of</strong> primary heart tumors are benign, with atrial myxomas<br />

comprising three-quarters <strong>of</strong> those, with the majority originating from the left atrium. Patients typically<br />

present most commonly with cardiovascular symptoms secondary to mitral valve obstruction such as<br />

heart failure and pulmonary hypertension. They may also present with neurologic deficits secondary to<br />

embolic phenomena, as well constitutional symptoms such as weight loss and fever. Asymptomatic<br />

presentation is extremely rare. In our case, the patient did not report to any symptoms <strong>of</strong> heart failure,<br />

fever or weight loss. The significance <strong>of</strong> the association <strong>of</strong> atrial myxoma and HCM is unclear. The<br />

number reported in the literature does not exceed a handful <strong>of</strong> cases. Both HCM and myxomas have<br />

been described in patients with progressive cardiomyopathic lentiginosis or LEOPARD syndrome, a rare<br />

autosomal dominant disease with complex features involving skin, skeletal and cardiovascular systems.<br />

The patient in this case did not have any features typical <strong>of</strong> lentiginosis. Management <strong>of</strong> asymptomatic<br />

cardiac myxomas remains an issue <strong>of</strong> debate, as there are no clear recommendations to suggest<br />

conservative versus surgical measures.<br />

Georgia.<br />

INTRODUCTION: Klebsiella Pneumonia meningitis in adults is rarely reported in North America. We<br />

report a case <strong>of</strong> an immunocompetent male with Klebsiella Pneumonia meningitis, which occurred as a<br />

result <strong>of</strong> a latent Strongyloides infestation.<br />

st1\:*{behavior:url(#ieooui) }<br />

CASE PRESENTATION: A 23 year old Mexican housekeeper with no known medical history presented<br />

to the emergency department with headache, fever, nausea, vomiting and photophobia. On<br />

examination, he was alert but uncomfortable with a temperature <strong>of</strong> 102.8 and nuchal<br />

rigidity. Laboratory studies showed a leukocyte count <strong>of</strong> 20.6 with 95.5% neutrophils. His head CT scan<br />

was normal. Lumbar puncture yielded clear CSF with a leukocyte count <strong>of</strong> 2130 (predominantly<br />

polymorphonuclear cells), total protein <strong>of</strong> 225 mg/dl, glucose <strong>of</strong> 39 mg/dl, and a gram stain that showed<br />

few white blood cells and no organisms. The patient was started on Ceftriaxone, Vancomycin, Ampicillin<br />

and Dexamethasone intravenously. Blood cultures were negative, but the CSF culture was positive for<br />

Klebsiella pneumonia that was sensitive to Ceftriaxone. Steroids and all other antibiotics were stopped<br />

and Ceftriaxone was continued for a total <strong>of</strong> 2 weeks. Subsequently, an induced sputum sample and<br />

multiple stool samples were collected and sent for microscopic examination. Strongyloides stercoralis<br />

larvae were present in the stool. However, serologic tests and sputum samples were negative. HIV<br />

testing was also negative. The patient was discharged without complications after 16 days.<br />

DISCUSSION: Infections with Klebsiella pneumonia are usually hospital-acquired and occur primarily in<br />

immunocompromised patients. In adults, bacterial meningitis caused by K. pneumonia is rare, but cases<br />

have been reported, especially in Asia. In a Taiwanese case series, the proportion <strong>of</strong> K. pneumonia<br />

meningitis rose from 8% between 1981-1986 to 18% between 1987-1995.<br />

Infections with enterobacteriaceae, such as Klebsiella pneumonia, are also associated with<br />

strongyloidiasis. Strongyloides is an intestinal roundworm that can persist and replicate within the host.<br />

Adult female worms live within small bowel epithelium where they deposit eggs. These eggs hatch and<br />

the larvae migrate into the lumen where they are excreted with feces, penetrate perianal skin to reenter<br />

the host ("autoinfection"), or go through the colonic mucosa to invade the<br />

bloodstream. Migrating larvae may transport gram negative bacteria to the bloodstream, resulting in<br />

sepsis, pneumonia, or meningitis.<br />

In this case, the cause <strong>of</strong> K. pneumonia meningitis is almost certainly due to migrating larvae. In a review<br />

<strong>of</strong> 38 cases <strong>of</strong> serious bacterial infections associated with strongyloidiasis, 21 (55%) had meningitis. In<br />

the 20 patients with a positive CSF culture, Klebsiella pneumonia was the second most common cultured<br />

organism.<br />

Conclusion: The goal <strong>of</strong> this report is to alert the medical community to the connection between gram<br />

negative infections and strongyloidiasis, particularly in patients from endemic areas.<br />

Arteriovenous Fistula Secondary to Renal Cell Carcinoma: An Uncommon Cause <strong>of</strong> High Output Heart<br />

Failure<br />

Robert Kung, MD, Salim Hayek,MD, Ilie Barb,MD, Viraj Master,MD, Sarfraz Ali,MD, Stephen<br />

Clements,MD<br />

INTRODUCTION: Arteriovenous fistula is a rare complication <strong>of</strong> renal cell carcinoma (RCC) but a<br />

reversible cause <strong>of</strong> high-output heart failure.<br />

CASE PRESENTATION: A 58 year-old male with uncontrolled hypertension presented to the emergency<br />

department complaining <strong>of</strong> worsening dyspnea on exertion, orthopnea and bilateral lower extremity<br />

edema <strong>of</strong> several months duration. On physical exam he appeared flushed, and exhibited signs <strong>of</strong><br />

hypervolemia, specifically jugular venous distention, diffuse bilateral crackles in all lung fields and warm<br />

lower extremities with bilateral pitting edema. Transthoracic echocardiogram (TTE) revealed a severely<br />

dilated left ventricle with severely reduced ejection fraction <strong>of</strong> 10%. Despite attempts to diurese and<br />

improve cardiac output with furosemide and milrinone, the patient’s renal function deteriorated. A<br />

Swan-Ganz catheter showed a paradoxically high output state with an elevated cardiac output <strong>of</strong> 15.2L<br />

and a cardiac index <strong>of</strong> 5.7 L/min/m 2 , raising suspicion for a systemic arteriovenous fistula.<br />

Retroperitoneal ultrasound revealed a s<strong>of</strong>t tissue density, further characterized by an MRI as a giant<br />

mass arising from the right kidney, with a dilated right renal vein consistent with a high flow state.<br />

Inferior vena cava catheterization revealed the venous blood above the renal veins had oxygen<br />

saturation 13% higher than below the renal veins. Right renal angiogram showed a highly vascular mass<br />

with feeder vessels, despite no obvious fistula seen. Radical right nephrectomy was performed and<br />

histopathology showed clear cell RCC. The presence <strong>of</strong> abnormally thickened arteriolar walls confirmed<br />

high grade flow and pressure consistent with AV shunting. Postoperatively, his renal function normalized<br />

and repeat TTE 7 days post-operatively showed significantly improved ejection fraction <strong>of</strong> 40% and a<br />

normal cardiac index <strong>of</strong> 2.6.<br />

DISCUSSION: Acquired AV fistulas are a rare complication <strong>of</strong> RCC. 30% present with cardiovascular<br />

symptoms, with high output heart failure being the most severe. Less than 30 cases have been described<br />

in the literature. In most instances, the diagnosis is established incidentally during angiography or<br />

surgery. The diagnostic workup <strong>of</strong> AV fistula in the setting <strong>of</strong> RCC has not been standardized. Venous<br />

oxygen saturation and renal angiography may be used to quantitate shunt flow. Resection <strong>of</strong> the<br />

neoplasm is associated with improvement in cardiac function and heart failure symptoms. This case also<br />

highlights how the initial TTE misled us to believe he was in a low cardiac output state; however, the<br />

velocity time integral, an indirect measure <strong>of</strong> cardiac output, was consistent with a high output state<br />

and attention to this would’ve prevented the delay in diagnosis.<br />

were stable. Physical exam was remarkable for significant bilateral lower extremity pitting edema.<br />

Further evaluation showed a random cortisol level <strong>of</strong> 1.0 mcg/dL, TSH was low/normal and free T4 was<br />

low. ACTH stimulation test revealed a cortisol <strong>of</strong> 2.0, 4.5 and 6.0 mcg/dL at 0, 30 and 60 minutes<br />

respectively, confirming adrenal insufficiency. ACTH was 15.1 pg/mL (10-60) and prolactin 38.2 ng/mL<br />

Anti-N-Methyl D-Aspartate Receptor Encephalitis: Rare Autoimmune Encephalitis as A Commonly<br />

Misdiagnosed Psychiatic Illness<br />

Ekamol Tantisattamo, MD; Melvin H.C. Yee, MD<br />

INTRODUCTION:Confounded by presenting with neuropsychiatric syndromes, anti-N-methyl Daspartate<br />

receptor (NMDAR) encephalitis is <strong>of</strong>ten misdiagnosed as psychiatric illness and delays the<br />

recognition. We report a case <strong>of</strong> man presenting with right leg stiffness, new-onset seizures, and<br />

fluctuating behavioral symptoms. Antiepileptics were started, and he was placed on Behavioral Health<br />

Hospital. Eventually serum anti-NMDAR antibody was found to be positive. The symptoms were<br />

resolved after plasmapheresis, high dose steroids, and rituximab were initiated.<br />

CASE PRESENTATION: A 27 year-old healthy man presented with recurrent episodes <strong>of</strong> short period <strong>of</strong><br />

stiffness and weakness <strong>of</strong> his right leg. He had ataxia and hyperreflexia on both ankles. Ten days later,<br />

he developed partial seizures with secondary generalization. Lumbar spine MRI showed degenerative<br />

disc disease in L5-S1 levels without spinal compression or disc herniation. Brain and neck MRI/MRA were<br />

unremarkable. Lumbar puncture was performed. Cerebrospinal fluid (CSF) was normal, and VDRL in CSF<br />

was non-reactive. Electroencephalogram revealed no epileptiform activity. Vitamin B12, TSH, ESR, and<br />

ANA were unremarkable. He was started on several anticonvulsants, but he could not tolerate side<br />

effects <strong>of</strong> the medications; therefore, all anticonvulsants were discontinued. He had a second episode <strong>of</strong><br />

seizures, and lacosamide was started. One month later, he started having behavioral change including<br />

agitation, combative, crying, and talkative. He wandered around his house. He had further deterioration<br />

<strong>of</strong> his cognitive status and episodes varying from catatonia to agitation and self immolation. Quatiapine<br />

was started to control the psychiatric symptoms. Because <strong>of</strong> worsening psychiatric symptoms, he was<br />

transferred to psychiatric behavioral health hospital. Extensive workups for his neuropsychiatric<br />

symptoms were performed due to unusual new-onset seizures and psychiatric symptoms. Serum anti-<br />

NMDAR IgG antibody was positive. Scrotal ultrasonography, chest CT scan, and whole body PET scan did<br />

not showed evidence <strong>of</strong> underlying malignancy. He was treated with high dose intravenous<br />

methylprednisolone and plasmapheresis for 5 treatments, and then was placed on maintenance oral<br />

prednisone and rituximab. He gradually returned to his baseline neurological status, and psychiatric<br />

symptoms were resolved.<br />

DISCUSSION: Sudden onset <strong>of</strong> leg stiffness, new-onset seizures, frontostriatal syndrome, and limbic<br />

symptoms in our young healthy patient is atypical, but may lead to misdiagnosis and treatment with<br />

antiepileptics and antipsychotics which have potential side effects. Anti-NMDAR encephalitis is very rare<br />

para- or nonparaneoplastic-related autoimmune encephalitis presenting with neuropsychiatric<br />

syndromes and seizures. As it is one <strong>of</strong> the autoimmune encephalitides which can be treated with<br />

dramatic response, a high index <strong>of</strong> suspicion and workups are warranted.<br />

Chapter Winning Abstract- Not a patient for hand clinic!<br />

Vijaya Sivalingam Ramalingam, MBBS-Associate<br />

INTRODUCTION:Superior pulmonary sulcus tumors (Pancoast tumors) were initially described by H.K.<br />

Pancoast in two publications, in 1924 and 1932. Musculoskeletal and neurological complaints being the<br />

predominant initial manifestation <strong>of</strong>ten mislead the clinician, thus delaying diagnosis and appropriate<br />

treatment. We report this case to emphasize the importance <strong>of</strong> considering Pancoast tumor in high risk<br />

patients with shoulder pain.<br />

CASE PRESENTATION: A 76 year old Caucasian man presented to the Emergency Department with<br />

worsening <strong>of</strong> right shoulder pain for 2 days. He gave a 6 month history <strong>of</strong> sharp, persistent, right<br />

shoulder pain, radiating to medial aspect <strong>of</strong> arm and forearm. It was associated with numbness and<br />

tingling. He was evaluated at the spine and hand clinics and eventually underwent carpal tunnel release<br />

and ulnar nerve reposition surgeries. Upon admission, examination revealed a hard, non mobile mass in<br />

the right supraclavicular fossa. Chest radiograph revealed a s<strong>of</strong>t tissue density in the right lung apex. CT<br />

chest demonstrated a right superior sulcus tumor with extension into the central spinal canal at the<br />

level <strong>of</strong> T1 and T2. MRI spine revealed a large right upper lobe apical mass involving the supraclavicular<br />

fossa, right posterior cervical space, prevertebral musculature with osseous and epidural invasion from<br />

C7 through T2 and multiple destructive s<strong>of</strong>t tissue masses involving the posterior ribs. A fine needle<br />

aspirate <strong>of</strong> supraclavicular portion <strong>of</strong> the lung mass demonstrated neoplastic plasma cells. A bone<br />

marrow biopsy confirmed multiple myeloma and he was diagnosed with an unusual case <strong>of</strong> Pancoast<br />

syndrome caused by multiple myeloma with extramedullary dissemination to lung. He completed a<br />

course <strong>of</strong> palliative radiation to the right lung mass and is currently on chemotherapy.<br />

DISCUSSION: Pancoast tumors are primarily non-small cell lung cancers. Multiple myeloma presenting<br />

as Pancoast syndrome is extremely rare. The prognosis <strong>of</strong> these patients is poor. The typical thoracic<br />

manifestations <strong>of</strong> multiple myeloma are bony involvement <strong>of</strong> the thoracic cage or a pulmonary infiltrate<br />

secondary to infection. These tumors, by their close vicinity to neurovascular structures like brachial<br />

plexus and subclavian vessels, <strong>of</strong>ten present with musculoskeletal pain and distal neurologic symptoms<br />

resulting in referral to orthopedicians or physiotherapists. Patients are initially treated for arthritis and<br />

bursitis <strong>of</strong> shoulder and a delay <strong>of</strong> 6-9 months have been reported in many cases before the tumor was<br />

discovered. Extensive tumors, diagnosed in late stages, have poor prognosis and are considered only for<br />

palliative therapy. We emphasize the importance <strong>of</strong> considering Pancoast tumor in the differential<br />

diagnosis and performing a thorough evaluation <strong>of</strong> the chest whenever middle-aged persons present<br />

with persistent shoulder or neck pain. This report will also help clinicians recognize the association<br />

between Pancoast syndrome and multiple myeloma.<br />

Chapter Winning Abstract<br />

Jeffrey Borgeson, Maryam Zia<br />

INTRODUCTION:Thrombocytopenia induced by viral infection is a well-documented phenomenon.<br />

Epstein-barr virus, parvovirus B19, HIV, and hepatitis viruses are all known to cause<br />

thrombocytopenia. CMV infection leading to thrombocytopenia in the organ transplant recipient and<br />

HIV patient is well known; however, CMV infection resulting in thrombocytopenia in the<br />

immunocompetent host is exceedingly rare. Here we present a case <strong>of</strong> CMV-induced severe<br />

thrombocytopenia in a young immunocompetent adult.<br />

CASE PRESENTATION: The patient was a 22-year old male with a history <strong>of</strong> Hodgkin's Lymphoma<br />

treated successfully by ABVD 8 years prior who presented to an outside institution with diffuse petechia<br />

and eccymoses after minor trauma. On examination he was found to have both oral mucosa and skin<br />

petechiae, and eccymoses over his right shoulder. He was without fever, lymphadenopathy, or<br />

splenomegaly on exam. His platelet count initially was 1000 per uL. At this point he was treated for a<br />

suspected ITP with steroids, intravenous immunoglobulin, and Rh immune globulin without a platelet<br />

response. HIV antibodies, hepatitis serologies, EBV, parvovirus B19, ANA, anti-platelet antibodies, and<br />

anti-phospholipid studies were all negative. Bone marrow examination showed a normal number <strong>of</strong><br />

megakaryocytes with normal morphology, so splenectomy was performed. Despite this, severe<br />

thrombocytopenia persisted. The patient was discharged home but was soon readmitted to our<br />

institution for melena, hematuria, and a platelet count <strong>of</strong> 16,000 per uL. The patent was treated with<br />

rituximab and romiplostim which resulted in platelet increases to 20,000/dl 1-hour after platelet<br />

transfusions that sustained for about 24 hours before drifting back down to the 5,000-10,000/dl range.<br />

In light <strong>of</strong> the transient response to platelet transfusions, other causes for the thrombocytopenia were<br />

considered and a CMV pcr was found to be positive at 137,000 copies/mL. All immunosuppressive<br />

therapies were held, and the patient was started on valgancyclovir orally. Within 3 weeks <strong>of</strong> initiation <strong>of</strong><br />

the antiviral therapy, his platelet count increased to 250,000 and his CMV viremia was<br />

suppressed. Three months after intiation <strong>of</strong> antiviral therapy his CMV viremia remains suppressed and<br />

his platelet count remains in the normal range.<br />

DISCUSSION: Although ITP refractory to corticosteroids at presentation can occur, failure <strong>of</strong> the initial<br />

line <strong>of</strong> therapy should prompt further investigation including bone marrow examination. In light <strong>of</strong> this<br />

patient’s prior treatment with chemotherapy, myelodysplastic syndrome was considered early in the<br />

differential diagnosis. There have been multiple cases reported in the literature <strong>of</strong> CMV-associated<br />

thromboyctopenia in the immunocompromised host with some cases responding to immunosuppressive<br />

therapy and others responding to antiviral therapy. Given our patient's poor response to<br />

immunosuppressive therapy, it is thought the patient experienced a direct cytopathic effect from CMV<br />

infection as opposed to immune globulin-mediated platelet destruction.<br />

Three faces <strong>of</strong> pylephlebitis: to anticoagulate or not to anticoagulate<br />

Ayokunle Temidayo Abegunde, MBBS, Waldo Herrera, MD, Naser Yamani, MD, Doris Galina, MD<br />

INTRODUCTION: Suppurative thrombosis <strong>of</strong> the portal vein (pylephlebitis) is a rare condition with an<br />

incidence <strong>of</strong> 0.01% in hospitalized patients, and a mortality rate <strong>of</strong> about 11 to 32%. The role <strong>of</strong><br />

anticoagulation in the treatment <strong>of</strong> pylephlebitis is unclear. Available evidence suggests that effective<br />

antimicrobials without anticoagulation can achieve re-canalization <strong>of</strong> the portal vein. Therefore, routine<br />

anticoagulation is not recommended unless there is evidence <strong>of</strong> progression despite adequate antibiotic<br />

therapy.<br />

CASE PRESENTATION: Objectives<br />

Describe the clinical presentation and report the outcome <strong>of</strong> a cluster <strong>of</strong> three cases <strong>of</strong> non-cirrhotic<br />

pylephlebitis managed with and without anticoagulation at our institution.<br />

Methods<br />

We report three cases <strong>of</strong> pylephlebitis with different clinical presentations, seen over an eight-week<br />

period. Only one <strong>of</strong> the three patients was treated with anticoagulation. The decision to give or not to<br />

give anticoagulation was made by the primary attending physician. After discharge from the hospital,<br />

patients were followed prospectively with abdominal CT scans to evaluate for recanalization <strong>of</strong> the<br />

portal vein. We also conducted a Medline review <strong>of</strong> the literature on the evidence <strong>of</strong> anticoagulation for<br />

pylephlebitis. The key words included were pylephlebitis, septic thrombophlebitis, and portal vein<br />

thrombosis.<br />

Results<br />

Three male patients with a mean age <strong>of</strong> 52.7 years (58, 53, 47 years) were admitted with acute<br />

cholecystitis, gastroenteritis, and cholangitis, respectively. Blood cultures were positive for<br />

Streptococcus millieri, Proteus mirabilis, and Bacteroides fragilis. Admission abdominal CT scans<br />

revealed acute thrombosis <strong>of</strong> the portal vein in all three patients. They all received culture directed<br />

antibiotics. In the patient treated with anticoagulation a CT scan <strong>of</strong> the abdomen performed six months<br />

after initial presentation revealed complete recanalization <strong>of</strong> the main portal vein with a small residual<br />

thrombus in its right branch. The two patients who did not receive anticoagulation had persistence <strong>of</strong><br />

portal vein thrombosis with cavernous transformation in the follow-up CT scan <strong>of</strong> the abdomen.<br />

DISCUSSION: Our small case series suggests that anticoagulation has a small benefit in achieving recanalization<br />

<strong>of</strong> the portal vein six months after diagnosing pylephlebitis. This is supported by our<br />

literature review that indicates a slight benefit <strong>of</strong> anticoagulation, particularly, in patients with<br />

progression <strong>of</strong> pylephlebitis, and/or hypercoagulable states. However, there is very limited information<br />

regarding the optimal duration <strong>of</strong> anticoagulation. The available evidence for anticoagulation in the<br />

management <strong>of</strong> pylephlebitis cannot be generalized to all patients. Therefore, clinical judgment on a<br />

case-by-case basis is advised.<br />

EBV VIREMIA CAUSING COLLAPSING FOCAL SEGMENTAL GLOMERULAR SCLEROSIS<br />

Kumar Kunnal Batra, MD Javier Gomez, MD<br />

INTRODUCTION: FSGS is a glomerulopathy most commonly associated with HIV infection. It is also<br />

associated with other infectious diseases such as parvovirus B19, cytomegalovirus, leishmaniasis,<br />

pulmonary tuberculosis, hepatitis C virus and HTLV-1 [1].<br />

We present a case <strong>of</strong> disseminated Epstein Barr virus (EBV) infection as a cause <strong>of</strong> collapsing focal<br />

segmental glomerular sclerosis (FSGS). To our knowledge, this association has never been reported in<br />

the medical literature.<br />

CASE PRESENTATION: A 21 year old female with no past medical history and no history <strong>of</strong> trauma,<br />

presented with complaints <strong>of</strong> dull left flank pain, fatigue, and subjective fevers. She was found to have<br />

temperature <strong>of</strong> 102.9 F, splenomegaly, and tenderness to palpation in left upper quadrant. Labs showed<br />

hemoglobin <strong>of</strong> 6.5 g/dl, WBC <strong>of</strong> 15,000 and 13% bands, as well as an LDH <strong>of</strong> 746 U/L. CT <strong>of</strong> the abdomen<br />

showed marked splenomegaly with areas <strong>of</strong> infarction.<br />

During her hospital course she continued to have fevers up to 103, and developed anasarca. Creatinine,<br />

which was normal on admission increased to 1.9 mg/dl, and she started having nephrotic range<br />

proteinuria, her LDH increased to 1273 U/L and she had persistent thrombocytosis. Renal biopsy showed<br />

collapsing FSGS. Further testing to determine the etiology <strong>of</strong> her collapsing FSGS including HIV Elisa and<br />

viral load, Blood and Urine cultures, Histoplasma serologies, Hepatitis serologies, CMV IgM, autoimmune<br />

panel, JAK-2 mutation, flow cytometry and bcr/abl mutation where all negative. Bone marrow biopsy<br />

did not show any abnormal cell clusters or morphology, favoring reactive thrombocytosis. EBV DNA and<br />

IgG and IgM for EBV viral capsid antigen were positive. Repeat CT showed worsening splenomegaly with<br />

approximately 50% <strong>of</strong> the spleen being infarcted so she was taken for splenectomy and her spleen<br />

biopsy showed multifocal infarctions with positive in-situ hybridization for EBV.<br />

The diagnosis <strong>of</strong> disseminated EBV infection with secondary collapsing FSGS was made. Her fevers<br />

improved after splenectomy. She was started on an enalapril for her proteinuria which gradually<br />

improved and her edema resolved.<br />

DISCUSSION: In this case the etiologic diagnosis <strong>of</strong> the patient’s collapsing FSGS was elusive at first<br />

because the evaluation for all the known causes <strong>of</strong> this disease was negative. However her clinical<br />

presentation led us to the consider a systemic EBV infection, this was confirmed by positive EBV IgG,<br />

IgM, viral capsid antigen, and EBV DNA [2]<br />

In our literature review, EBV infection as the etiology <strong>of</strong> collapsing FSGS has never been reported; hence<br />

this would be the first case description <strong>of</strong> such an association.<br />

EBV infection should be included as one <strong>of</strong> the possible etiologies <strong>of</strong> non HIV related collapsing FSGS<br />

In our patient, the clinical course was benign with full recovery <strong>of</strong> renal function.<br />

Ventricular Myxoma: A Case Of An Elephant In The Chest<br />

Stephen A Boateng, DO Bruce Wilson, MD Jason Robin, MD<br />

INTRODUCTION: A NSTEMI secondary to coronary occlusion has been encountered by almost every<br />

internist. However, the etiology <strong>of</strong> this phenomenon may not always be so familiar. This case highlights<br />

the importance <strong>of</strong> a broad differential when confronted with the routine.<br />

CASE PRESENTATION: A 74 yo white male with a history <strong>of</strong> hypertension, and hyperlipidemia,<br />

presented to the emergency department with chest tightness and pressure. These symptoms started<br />

the previous day while he was exercising on a treadmill. He denied any other associated symptoms. His<br />

family history was significant for a father and 3 paternal uncles who died <strong>of</strong> myocardial infarctions in<br />

their fifties. He had never smoked and exercised four times a week.<br />

Physical exam was unremarkable. Cardiac markers were elevated and an EKG revealed a new left bundle<br />

branch block. A cardiac catheterization proved insignificant for occlusive CAD. Echocardiography,<br />

however, revealed a large, mobile left ventricular mass. A Cardiac MRI further characterized the mass<br />

and a small transmural infarct <strong>of</strong> the basal septum was noted. On pathological exam, the gross findings<br />

<strong>of</strong> the tumor were consistent with a myxoma. Surgical excision was then performed and after a few days<br />

in the unit, the patient was discharged home without any further complications.<br />

DISCUSSION: Primary cardiac tumors are very rare (0.1 percent incidence). Myxomas account for half<br />

<strong>of</strong> all cardiac tumors; however, ventricular myxomas are extremely rare as almost all myxomas occur in<br />

the left atrium. The classic triad <strong>of</strong> clinical symptoms, with which patients present, is congestive heart<br />

failure (67%), signs <strong>of</strong> embolization (29%), systemic or constitutional symptoms such as fever, or fatigue<br />

(17%). Thus, our patient’s sole presenting symptom <strong>of</strong> angina was atypical, and may be explained by<br />

intracardiac obstruction to blood flow. In about 5% <strong>of</strong> patients, these tumors are familial and follow an<br />

x-linked inheritance pattern (The Carney Complex).<br />

A transthoracic echocardiogram (TTE) is useful in the early detection <strong>of</strong> cardiac masses. A cardiovascular<br />

MRI is, however, preferable for the diagnosis and characterization <strong>of</strong> cardiac masses. It provides a wide<br />

field <strong>of</strong> view, generates high contrast and spatial resolution, performs multiplanar imaging, and allows<br />

precise localization and characterization <strong>of</strong> a mass. Thus, it arms the clinician with precise information in<br />

the absence <strong>of</strong> a tissue diagnosis.<br />

For most myxomas, surgical intervention is usually curative, and local recurrence is very rare. When left<br />

untreated, however, the complications from such tumors can be grave - congestive heart failure, sudden<br />

death, cardiac arrhythmias, infections, or embolization to vital organs such as the kidney or brain. This<br />

case highlights the importance <strong>of</strong> maintaining a broad differential in our approach to cardiac ischemia.<br />

While atherosclerosis is the most common cause; it is only one <strong>of</strong> many causes and the clinician should<br />

always maintain a keen judgement.<br />

PAINFUL THIGH – ARE WE MISSING THE DIAGNOSIS?<br />

Kalyani Chandra Second Author: Kiran Narreddy Faculty Author: James Kumar<br />

INTRODUCTION: Immunosuppression predisposes to a wide variety <strong>of</strong> infections, some <strong>of</strong>ten<br />

underdiagnosed due to lack <strong>of</strong> suspicion. Awareness about such conditions helps in early diagnosis and<br />

treatment, preventing significant mortality and morbidity. We here report a case <strong>of</strong> spontaneous<br />

pyomyositis in an undiagnosed Diabetes Mellitus (DM).<br />

CASE PRESENTATION: A 58-year-old Caucasian male with no significant past medical history presented<br />

to the clinic with chief complaint <strong>of</strong> bilateral thigh pain <strong>of</strong> four weeks duration. Pain was 10/10 constant,<br />

non-radiating, aggravated by walking, no significant relieving factors, associated with intermittent fever<br />

and chills. He recently had few long drives. No history <strong>of</strong> trauma, sick contacts, or recent illness. Family<br />

history was positive for DM in father and sister. On examination, a tender cord like structure was<br />

palpated on medial left thigh and tenderness elicited over medial right thigh. No regional<br />

lymphadenopathy. Distal pulses normal. Bilateral lower extremity duplex ruled out deep venous<br />

thrombosis, but showed a non-vascular structure suspicious for hematoma or abscess in both thighs.<br />

Initial labs were remarkable for glucose <strong>of</strong> 444mg/dl. D-dimer and creatine kinase levels were within<br />

normal limits. Magnetic resonance imaging (MRI) <strong>of</strong> both thighs showed signal characteristics suggestive<br />

<strong>of</strong> intramuscular abscess. He was hospitalized and Computed tomography (CT) guided drainage <strong>of</strong> the<br />

intramuscular abscess was done which grew Staphylococcus aureus sensitive to methicillin. Glycosylated<br />

hemoglobin was 11.4%. Patient responded well to good glycemic control and intravenous antibiotics.<br />

Follow up CT scan <strong>of</strong> thighs showed decrease in size <strong>of</strong> the abscesses.<br />

DISCUSSION: Very few cases <strong>of</strong> pyomyositis as the initial manifestation <strong>of</strong> DM have been reported.<br />

Pyomyositis, also called pyomyositis tropicans due to its endemicity in tropical regions, is increasing in<br />

incidence in the temperate regions, with immunosuppression being a significant predisposing factor.<br />

Most common site is thigh (54%), followed by back (13%). It is not always trauma related. Creatine<br />

kinase levels are <strong>of</strong>ten normal. 75-90% <strong>of</strong> cases are caused by Staphylococcus aureus with mortality <strong>of</strong><br />

up to 10%. CT guided drainage helps in optimizing treatment. Painful thigh in patients with DM,<br />

immunodeficiency, malignancy, cirrhosis, renal insufficiency, organ transplant, intravenous drug abuse<br />

and those on immunosuppressive agents should raise high index <strong>of</strong> suspicion for pyomyositis. Timely use<br />

<strong>of</strong> CT or MRI helps in early diagnosis and initiation <strong>of</strong> treatment thereby preventing significant morbidity<br />

and mortality.<br />

I have tried everything for this headache Doc. It just doesn’t go away!!<br />

Jatin Chhabra, MD Second Author: Puneet Agarwal, MD Third Author: Nil<strong>of</strong>ar Rahman, MD<br />

INTRODUCTION:Headache is a very common complaint amongst patients presenting to the primary<br />

care physician (PCP). Its overall prevalence is estimated to be around 12 to 16% in North America and<br />

Europe. Most headaches are benign and are not associated with a potentially life threatening illness.<br />

However, a detailed history and physical examination are the keys to distinguishing potentially serious<br />

from benign headaches. Here is a case report <strong>of</strong> a 32 year old female who presented with a rare cause <strong>of</strong><br />

headache.<br />

CASE PRESENTATION: A 32 year old female with a past medical history <strong>of</strong> migraines presented to her<br />

PCP with worsening headaches for the last one week. Her exact words were “this headache just feels a<br />

little different Doc.” She was sent home with Sumatriptan for acute attacks, having already been well<br />

controlled until recently on prophylactic topiramate therapy. A few days later, the patient presented to<br />

the Emergency Department with generalized tonic clonic seizures. A CT Brain without contrast only<br />

showed a s<strong>of</strong>t tissue attenuation in the right maxillary sinus suggestive <strong>of</strong> sinusitis. Review <strong>of</strong><br />

medications revealed that the patient had been on oral contraceptive pills (OCPs). Papilledema was seen<br />

on funduscopy. A subsequent MRI Brain showed mildly increased signal with mild diffuse restriction in<br />

the high left frontoparietal lobe. MRV <strong>of</strong> the brain confirmed a subtotal thrombosis <strong>of</strong> the superior<br />

sagittal sinus possibly extending into the left transverse sigmoid sinus and jugular foramen. She was<br />

started on a heparin infusion and antiseizure medication (levetiracetam and topiramate) and was<br />

subsequently discharged after bridging over to warfarin. The hypercoagulable workup sent prior to<br />

initiating anticoagulation came back as unremarkable.<br />

DISCUSSION: Cerebral sinus venous thrombosis (CSVT) is a rare but distinct cerebrovascular disorder<br />

that most <strong>of</strong>ten affects young adults and children. The estimated annual incidence is 3 to 4 cases per 1<br />

million population. Headache is the most common symptom, occurring in up to 89-90% <strong>of</strong> cases and<br />

seizures in 40%. Other signs <strong>of</strong> intracranial hypertension such as papilledema may also be seen, hence a<br />

fundoscopic examination in a patient presenting with headaches (and red flags such as in this case) is<br />

indispensable. Major risk factors for CSVT include prothrombotic conditions, OCPs, pregnancy,<br />

malignancy, infection and head injury. A head CT may be normal in up to 30% <strong>of</strong> cases and show indirect<br />

signs in around 40% <strong>of</strong> cases. However the accuracy is 90-100% when combined with a CT venography<br />

or MR venography. As a result, I think this case rightly highlights the importance <strong>of</strong> a good history<br />

(identifying red flags) and physical examination including fundoscopy in an outpatient setting!!<br />

Acute Coronary Syndrome due to an unusual variant <strong>of</strong> Coronary Artery Disease!!<br />

Jatin Chhabra, MD Second Author: Puneet Agarwal, MD Fourth Author: Nil<strong>of</strong>ar Rahman, MD<br />

INTRODUCTION:Acute coronary syndrome (ACS) refers to a spectrum <strong>of</strong> diseases ranging from<br />

unstable angina (UA), to non–ST-elevation myocardial infarction (NSTEMI), to ST-elevation myocardial<br />

infarction (STEMI). In the majority <strong>of</strong> cases, it is due to atherosclerosis <strong>of</strong> the coronary arteries or<br />

coronary artery disease (CAD). CAD is a major cause <strong>of</strong> death and disability in developed countries,<br />

accounting for about one third <strong>of</strong> all deaths over the age <strong>of</strong> 35. Here is a case <strong>of</strong> a young 49 year old<br />

man who presented with NSTEMI due to a relatively rare variant <strong>of</strong> CAD.<br />

CASE PRESENTATION: A 49 year old African <strong>American</strong> male with a past medical history <strong>of</strong> hypertension<br />

and HIV infection presented to the Emergency Department with classic substernal squeezing chest pain<br />

radiating to the left arm. The EKG showed non specific ST-T segment changes and Troponin I went up to<br />

0.17 ng/ml. Despite an Aspirin, two sublingual nitroglycerines and nitropaste, the patient’s pain<br />

persisted, though less in intensity. CT Chest with contrast was negative for pulmonary embolism. He was<br />

started on a heparin infusion and a subsequent coronary angiography revealed nonobstructive coronary<br />

atherosclerosis, ectatic coronary arteries and a 1.5-2cm aneurysm <strong>of</strong> the mid segment <strong>of</strong> the left<br />

anterior descending artery. No thrombus was noted in the aneurysm and the left ventricular systolic<br />

function was normal (EF 55%). His pain gradually abated while on the heparin infusion and he was<br />

subsequently discharged home on warfarin.<br />

DISCUSSION: Coronary artery aneurysm (CAA) is defined as a localized dilatation exceeding the<br />

diameter <strong>of</strong> the adjacent normal coronary segment by more than 50%. The prevalence ranges from 1.5<br />

to 5% in patients with CAD. Over 50% <strong>of</strong> the aneurysms are atherosclerotic in origin and are considered<br />

a variant <strong>of</strong> CAD, but the exact mechanism leading to the development <strong>of</strong> ectasia in these vessels is<br />

unknown. It is most common in the right coronary artery and least in the left main coronary. The second<br />

most common cause is Kawasaki disease followed by congenital etiology, autoimmune disease, trauma,<br />

dissection, infection and angioplasty. The main complications include thrombosis, distal embolization,<br />

rupture and vasospasm. Coronary angiography is the gold standard but transesophageal<br />

echocardiogram is a good tool and can be used to follow changes in size, especially for proximal<br />

segments. In the absence <strong>of</strong> obstructive CAD, definitive treatment is unclear but usually includes only<br />

medical therapy (antiplatelet therapy and anticoagulation) as in this case. With coexisting significant<br />

flow limiting disease or a giant aneurysm (>2cm), surgical therapy or percutaneous stent placement is<br />

essential. Our patient may have had thrombus formation, rapid dissolution <strong>of</strong> the clot and distal<br />

microembolization.<br />

An Unusual Case <strong>of</strong> Abdominal pain<br />

Swapna Devanna, Co Authors: Adam King, Dheeraj Reddy, Mudita Bhugra, Aman Ali<br />

CASE PRESENTATION: A 41-year-old male presented with third episode <strong>of</strong> Right Upper Quadrant<br />

(RUQ) and epigastric pain in last four months. Abdominal pain radiated to his back and was aggravated<br />

by eating. He also has tea colored urine and pale stool. On a physical exam, he had positive Murphy’s<br />

sign, diffuse abdominal pain and mild icterus. His laboratory data showed elevated liver enzymes,<br />

amylase, lipase and direct bilirubin. His CT scan <strong>of</strong> Abdomen was consistent with pancreatitis and RUQ<br />

ultra sonogram was negative for choledocholithiasis. He had ERCP/EUS with stent placement in<br />

Common Bile Duct (CBD) without evidence <strong>of</strong> pancreatic mass or stones. He had negative work up for<br />

other causes <strong>of</strong> pancreatitis except for elevated IgG4 and CA 19-9. Biopsy specimens were negative for<br />

malignancy. Specimen sent to the mayo clinic showed numerous IgG with only rare IgG4 positive plasma<br />

cells. Diagnosis <strong>of</strong> Autoimmune pancreatitis is considered. After initiation <strong>of</strong> steroid treatment patient<br />

had significant improvement in his symptoms and appearance <strong>of</strong> CBD and pancreas on repeat<br />

ERCP/EUS. His liver and pancreatic enzymes also normalized.<br />

DISCUSSION: Autoimmune pancreatitis (AIP) has prevalence <strong>of</strong> 0.7 per 100,000. 85% <strong>of</strong> patients are<br />

males who are more than 55 years <strong>of</strong> age. It may be associated with other autoimmune diseases.<br />

Obstructive symptoms are most common presenting symptom. 47% <strong>of</strong> these patients have elevated<br />

CA19-9, which normalizes after steroid treatment in almost all patients. On Histology, they have<br />

lymphocytic infiltration with plasma cells, which typically expresses IgG4. Sausage shaped appearance <strong>of</strong><br />

the pancreas and long non-beaded appearance <strong>of</strong> CBD and intrahepatic bile ducts are common features<br />

seen on CT scan.<br />

Autoimmune pancreatitis (AIP) can be particularly challenging to diagnose because it closely resembles<br />

pancreatic cancer. There is no single test or characteristic feature that can be used to identify AIP. Mayo<br />

Clinic HISTORt diagnostic guidelines for AIP is helpful, so that the disorder can be correctly identified and<br />

unnecessary surgery be avoided. The HISTORt criteria include Histology, Imaging, Serology, other organ<br />

involvement and response to steroid therapy. Imaging <strong>of</strong> the pancreas is the first step in diagnosing AIP.<br />

A common feature <strong>of</strong> AIP is elevated serum IgG4. Because AIP is the only pancreatic disorder known to<br />

respond to corticosteroids, trial course <strong>of</strong> this drug is used to confirm a diagnosis. If symptoms improve,<br />

for instance, IgG4 level drops or a mass in pancreas shrinks patients are considered to have AIP. Before<br />

starting corticosteroids treatment, it is imperative to exclude malignant process in pancreas that mimics<br />

the presentation <strong>of</strong> AIP.<br />

A 48-year-old Chinese Man With Unremitting Fever<br />

Deepa Dharanipragada, MBBS Second Authors: Seshan Subramanian, MD, Third Author: Carlos F Garcia,<br />

MD<br />

INTRODUCTION: Hemophagocytic lymphohistiocytosis (HLH) is challenging diagnosis to make given its<br />

rarity and dynamic presentation patterns. We discuss a case <strong>of</strong> Epstein-Barr virus (EBV)-associated HLH<br />

which masqueraded as sepsis.<br />

CASE PRESENTATION: A 48-year-old Chinese man with no known medical problems presented with<br />

fever, weight loss, and upper respiratory tract infection for one month. On examination, he was<br />

tachycardic, tachypneic, hypotensive and febrile with 39.4 centigrade. There was no rash,<br />

lymphadenopathy or appreciable organomegaly. The rest <strong>of</strong> the examination was unremarkable. The<br />

chest x-ray showed no acute cardiopulmonary process. He was hemodynamically stabilized with<br />

intravenous fluids, pancultured and started on empiric antimicrobials. Despite this, unremitting fever<br />

continued. Detailed investigative work-up was significant for pancytopenia, normal fibrinogen level,<br />

hyponatremia, hypoalbuminemia, transaminitis, mild elevation <strong>of</strong> triglycerides and a negative<br />

monospot. Pan-computed tomography showed maxillary sinusitis and splenomegaly. Bone marrow<br />

biopsy revealed focal areas <strong>of</strong> hemophagocytosis. HLH was suspected. Ferritin level was ordered and<br />

was found to be 11,862 ng/ml confirming the diagnosis <strong>of</strong> HLH. Extensive work-up to determine etiology<br />

continued, as management <strong>of</strong> HLH differs based on the underlying cause. Infectious and autoimmune<br />

work-up was negative except for viral serologies consistent with previous exposure to EBV. At this<br />

point, he was started on steroids, resulting in symptomatic improvement. Antimicrobials were<br />

discontinued. He was discharged home afebrile with outpatient follow-up. Four days later, he was<br />

readmitted with fever and fatigue despite his compliance with prednisone. Oral cavity showed exudates.<br />

Pancytopenia and transaminitis worsened. Vancomycin and acyclovir were addded to prednisone<br />

empirically. Repeat panculture and monospot test were negative. Repeat bone marrow biopsy showed<br />

focal areas <strong>of</strong> hemophagocytosis with no signs <strong>of</strong> malignancy. Given the positive EBV serology, Epstein-<br />

Barr viral load was ordered. A trial <strong>of</strong> intravenous immunoglobulin led to hypotension with further<br />

worsening <strong>of</strong> fever and pancytopenia. Empiric management for neutropenic fever was started. The<br />

following day, Epstein-Barr viral load results became available and showed 1,018,245 copies/ml leading<br />

to a diagnosis <strong>of</strong> EBV-associated HLH. The patient was started on etoposide with subsequent significant<br />

improvement in symptoms.<br />

DISCUSSION: HLH encompasses immune dysregulation and cytokine storm. It can develop subsequent<br />

to genetic mutations or in association with infection, malignancy or autoimmune conditions. Timely<br />

diagnosis and identification <strong>of</strong> the underlying cause is critical to effectively manage this potentially lethal<br />

condition. Five <strong>of</strong> the following eight criteria are needed for the diagnosis <strong>of</strong> HLH: fever, bicytopenia,<br />

splenomegaly, hypertriglyceridemia and/or hyp<strong>of</strong>ibrinogemia, hemophagocytosis, low or absent NK-cell<br />

activity, hyperferritinemia, increase in soluble CD25 levels. Management <strong>of</strong> EBV-associated HLH should<br />

be geared at reducing the uncontrolled immune response and elimination <strong>of</strong> EBV infection. Studies<br />

showed survival benefit with early administration <strong>of</strong> etoposide in EBV-associated HLH.<br />

Catecholaminergic Polymorphic Ventricular Tachycardia: A Stress induced Phenomenon.<br />

Kinza Gul M.D Saad Muhammad M.D, Prakash Thopiah M.D<br />

INTRODUCTION:Although catecholaminergic polymorphic ventricular tachycardia (CPVT) is rarely<br />

encountered, physicians should be aware <strong>of</strong> this fatal arrhythmia. It can present in susceptible<br />

individuals most likely during a stress test. A careful personal and family history is important to suspect<br />

this disorder although sporadic cases can also manifest for the first time. Once diagnosed, it is important<br />

to initiate adequate treatment and proper counseling.<br />

CASE PRESENTATION: A 44 year old man, with no significant past medical history, was admitted to the<br />

hospital for further evaluation <strong>of</strong> intermittent chest pain. He had no similar episodes in the past. He<br />

denied symptoms <strong>of</strong> dizziness, syncope or shortness <strong>of</strong> breath. His father had premature coronary artery<br />

disease. Otherwise, no history <strong>of</strong> arrhythmia or sudden cardiac death was reported in family. Physical<br />

exam, including vitals, was normal. Serial cardiac biomarkers and EKG were also normal. He underwent<br />

an exercise stress echocardiogram during which he felt lightheaded. His heart rate escalated from 160<br />

beats per minute to 255 beats per minute. Corresponding EKG recording revealed a polymorphic<br />

ventricular tachycardia. The test was stopped and prompt return to normal sinus rhythm was noted on<br />

cessation <strong>of</strong> exercise. A trans-thoracic echocardiogram did not show any abnormality. His serum<br />

chemistry, including a magnesium level, was normal. Patient later underwent coronary artery<br />

catheterization, which was also unremarkable. He was started on oral beta-blocker therapy and<br />

remained asymptomatic until he was discharged home. A close follow up with cardiology clinic was<br />

scheduled for evaluation for implantable cardioverter-defibrillator (ICD) placement.<br />

DISCUSSION: Exercise stress test is commonly performed in the hospital. Very rarely, we may<br />

encounter young patients experiencing a fatal arrhythmia during testing. Catecholaminergic<br />

polymorphic ventricular tachycardia is one such arrhythmia. It is a familial disorder, with mutation<br />

identified in two genes (RyR2 and CASQ2). Sporadic cases without family history may also be<br />

encountered. The estimated prevalence <strong>of</strong> CPVT is 1:10,000. It can be precipitated due to emotional or<br />

physical stress. Symptoms at presentation may vary from syncope or dizziness to sudden cardiac death.<br />

Affected individuals have a structurally normal heart and a normal baseline electrocardiogram.<br />

Diagnosis is clinical, based on positive family history and response to exercise or catecholamine infusion.<br />

Management involves avoidance <strong>of</strong> competitive sports, initiation <strong>of</strong> beta blocker therapy and most<br />

patients may ultimately require an ICD placement to avoid sudden cardiac death.<br />

Is this a risk-free approach to overcome obesity?<br />

Samrina Hassan, MBBS, MD Second Author: Puneet Agarwal, MBBS, MD Third Author: Jatin Chhabra,<br />

MBBS, MD Fourth Author: Andy Arwari, MD<br />

INTRODUCTION: Obesity is one <strong>of</strong> the major risk factors for cardiovascular disease, certain types <strong>of</strong><br />

cancer, and type-2 diabetes. Healthy eating and regular physical activity is the recommended approach<br />

to weight reduction. We present a different approach to weight reduction, undertaken by one <strong>of</strong> our<br />

patients and the consequences she encountered.<br />

CASE PRESENTATION: Our patient is a 36 year-old woman (BMI 39) with a history <strong>of</strong> migraine with<br />

visual aura, who presented to the emergency department with complaints <strong>of</strong> a headache, associated<br />

with retro-orbital pain and photophobia, weakness in left upper extremity, and slurred speech. She<br />

denied dizziness, nausea, vomiting or balance problems. After an unremarkable CT <strong>of</strong> the brain without<br />

contrast, CT <strong>of</strong> the brain with perfusion revealed occlusion <strong>of</strong> the right middle cerebral artery at the M1<br />

segment. She did not receive tissue plasminogen activator given her delayed presentation. MRA <strong>of</strong> the<br />

brain and neck was unremarkable but MRI <strong>of</strong> the brain was most consistent with an area <strong>of</strong> acute right<br />

basal ganglia infarction. Trans-esophageal echocardiogram was normal. Laboratory evaluation was<br />

negative for a hypercoagulable state. ANA was positive at 1:160, but the lupus panel was entirely<br />

negative otherwise. On detailed questioning, it was noted that for the last six months, she was on oral<br />

contraceptive pills and had been taking over the counter weight reduction supplements, which<br />

contained synephrine as one <strong>of</strong> the active ingredients. Both these medications were held since<br />

admission in view <strong>of</strong> a probable role in causing the stroke. She was started on aspirin and a statin and<br />

discharged home after improvement in symptoms. On follow-up, she was noted to have some residual<br />

weakness in the left upper extremity.<br />

DISCUSSION: Our case illustrates the association <strong>of</strong> weight-reduction products with acute stroke,<br />

especially the ones marketed as ephedra-free compounds. After the ban on ephedra-containing<br />

products, it has led to the emergence <strong>of</strong> new formulations which are ‘ephedra-free’ but contain other<br />

sympathomimetic agents such as synephrine, the safety <strong>of</strong> which is not yet established. Synephrine is<br />

similar to ephedra in chemical composition and mechanism <strong>of</strong> action, but its cardiovascular effects have<br />

not been extensively studied. Young obese adults like our patient are more inclined to use these<br />

products. The critical intervention would be to regulate marketing <strong>of</strong> such products and implement<br />

restrictions on their ‘over the counter’ sale to prevent further use and its complications, until extensively<br />

studied. At the same time, the importance <strong>of</strong> a detailed medication history including ‘over the counter’<br />

medications cannot be further emphasized.<br />

Neurosyphilis Treatment Failure or Ser<strong>of</strong>ast Syphilis: To Treat or Not To Treat.<br />

Prantesh Jain, MD Shweta Gupta MD<br />

INTRODUCTION:Neurosyphilis can present with personality changes alone, a manifestation <strong>of</strong>ten<br />

misdiagnosed as psychiatric problem. Another not so well-known issue is the concept <strong>of</strong> 'ser<strong>of</strong>ast'<br />

syphilis. This case highlights these issues and uncertainties associated with them.<br />

CASE PRESENTATION: A 58-years old lady with past-history <strong>of</strong> hypertension presented with<br />

progressively worsening personality changes for two-years, including difficulty remembering things,<br />

answers to questions being out <strong>of</strong> context with progressive unsteady gait requiring some support while<br />

turning. She became socially withdrawn and lost her job. She was sexually inactive for 30-years with no<br />

history <strong>of</strong> sexually transmitted diseases. Physical examination showed normal vital signs. Systemic exam<br />

was unremarkable except neurological exam which was remarkable for mini-mental exam 26/30 with<br />

difficulty in immediate recall, deep-tendon reflexes 3+ bilaterally and extensor-planter response. Gait<br />

was unsteady with difficulty in tandem-walking. She had normal serum chemistry, blood counts, thyroidfunction<br />

tests and vitamin-B12 levels. HIV serology was negative.<br />

MRI-brain revealed multiple areas <strong>of</strong> increased signal intensity bilaterally in cerebral white matter at the<br />

subcortical, peri-ventricular region. Serum RPR was positive, titer 1:128. CSF analysis showed normal<br />

glucose, elevated proteins 129mg/dL and WBC count 6/µL with 90% lymphocytes. CSF-VDRL was<br />

positive. She was treated with penicillin-G IV for 14 days and given a cane to support walking. Over next<br />

8 months her personality changes improved near-baseline and she was able to walk without support.<br />

She started a job. However her serum-RPR remained positive, titer 1:64 and repeat CSF showed elevated<br />

proteins with positive CSF-VDRL. She was re-treated for neurosyphilis with 2 weeks <strong>of</strong> IV penicillin.<br />

Another ten months later, patient was asymptomatic, but RPR remained positive, titer 1:64 with positive<br />

CSF-VDRL. She received a third course <strong>of</strong> penicillin, this time with probenecid. Then, it was concluded<br />

that the patient may have ser<strong>of</strong>ast syphilis and was observed. Her RPR titer 30-months after initial<br />

diagnosis declined two-fold only to 1:32 and post 42-months <strong>of</strong> diagnosis was 1:16. She continued to do<br />

well clinically.<br />

DISCUSSION: Neurosyphilis can present with variety <strong>of</strong> clinical and psychiatric symptoms alone or in<br />

combination, both <strong>of</strong> which the clinician needs to be aware <strong>of</strong> to make a correct diagnosis. An important<br />

issue is definition <strong>of</strong> 'ser<strong>of</strong>ast' syphilis. Traditionally defined in primary syphilis as persistently elevated<br />

serum-VDRL titers after adequate treatment and resolution <strong>of</strong> symptoms, its definition in tertiary<br />

syphilis remains unclear. The CSF protein and pleocytosis remain a better indicator <strong>of</strong> persistent disease<br />

than CSF-VDRL, which may take a very long time to become negative. However, the question <strong>of</strong> retreatment<br />

becomes important in a patient who becomes asymptomatic but continues to have increased<br />

CSF proteins. A negative CSF-FTA (fluorescent treponemal antibody) test can help identify active disease<br />

but is not recommended by CDC for diagnosing persistent disease and not widely available, making the<br />

diagnosis <strong>of</strong> persistent neurosyphilis a challenge. Hence, the question <strong>of</strong> re-treating the numbers or<br />

symptoms in neurosyphilis still remains debatable.<br />

Ascariasis Presenting As A Polyarthropathy That Resolved After Eradication<br />

Kovalsky A, Schrantz S University <strong>of</strong> Chicago - Northshore (both authors)<br />

INTRODUCTION:Enteropathic arthropathies comprise a spectrum <strong>of</strong> disorders, among them reactive<br />

arthritides and spondyloarthropathies. Reactive arthritis is usually associated with bacterial pathogens,<br />

but cases due to parasites have also been reported. Literature on arthropathies attributable to parasitic<br />

infection is limited to two reviews and a handful <strong>of</strong> case reports. Since 1951, only three case reports<br />

cited Ascaris lumbricoides as the causative pathogen. We report a fourth case <strong>of</strong> polyarthropathy that<br />

resolved after eradication <strong>of</strong> Ascariasis.<br />

CASE PRESENTATION: A 27-year-old female with no significant history presented for swollen knees<br />

and ankles. She reported two weeks <strong>of</strong> swelling ankles, followed by swollen knees and eventually also<br />

wrists. Her pain was minimal but was exacerbated when she was seated for long periods. She had been<br />

living in Ukraine the past year. Two weeks prior to onset she traveled to the Karpathian mountains, a<br />

week prior to onset she noted one day <strong>of</strong> fever <strong>of</strong> 38.9 o C associated with forceful vomiting, and four<br />

days later she had a few days <strong>of</strong> diarrhea. Other history included occasional alcohol consumption and<br />

freelance employment as a translator and editor. Family history and review <strong>of</strong> systems were<br />

negative. On exam she was fair-skinned and healthy-appearing, and had bilateral two-plus non-pitting<br />

ankle edema and bilateral knee effusions; exam was otherwise unremarkable. Laboratory studies<br />

obtained in Ukraine included normal hematologic studies but differential significant for 27% eosinophils,<br />

normal chemistries, normal liver studies, and negative CRP, RF, ANA, and ASO. Abdominal ultrasound<br />

was also normal. We ordered stool studies for ova and parasites, which were positive for Ascaris<br />

lumbricoides. She was treated with a single course <strong>of</strong> albendazole. Stool studies were repeated and<br />

positive at two weeks, and negative at four and eight weeks. Her joint edema and discomfort improved<br />

slowly, at six weeks had resolved completely, and at twelve weeks had not recurred.<br />

DISCUSSION: Reactive arthritis occasionally has been associated with helminth infection, and rarely<br />

with Ascariasis. Fever can increase activity <strong>of</strong> the parasite, and we suspect that our patient's febrile<br />

diarrheal illness was an unrelated infection that increased the activity <strong>of</strong> the ascarids, resulting in<br />

circulation <strong>of</strong> higher titers <strong>of</strong> arthrogenic antigens and triggering her arthropathy. This resolved<br />

completely upon eradication <strong>of</strong> the ascarids. This case describes an arthropathy in a healthy young<br />

woman with no rheumatologic conditions that resolved after eradication <strong>of</strong> concurrent<br />

Ascariasis. While Ascaris lumbricoidies is usually associated with tropical climates, it can also be found in<br />

temperate regions <strong>of</strong> Europe and the United States. It is conceivable that parasitic arthropathies are<br />

underreported and a thorough history including travel, as well as stool studies, should be considered in<br />

any patient presenting with an arthropathy and an otherwise negative workup.<br />

A Case <strong>of</strong> Corynebacterium Jeikeium Osteomyelitis<br />

Geeta Kutty, MD Bhanushali Keerti<br />

INTRODUCTION:Corynebacterium jeikeium is recognized as an important nosocomial pathogen among<br />

immunosuppressed patients and causes extremely severe clinical manifestations, which may be fatal if<br />

left untreated. A unique case <strong>of</strong> vertebral osteomyelitis, where Corynebacterium jeikeium was isolated<br />

as the causative bacterium in an immunocompetent patient with no risk factors, is presented below.<br />

CASE PRESENTATION: A 37 year old man with no significant past medical history presented with<br />

bilateral lower extremity weakness and numbness for 3 month. Pertinent physical findings included<br />

normal vitals, clinical signs <strong>of</strong> upper motor neuron involvement and intact cranial nerves. Laboratory<br />

data revealed normal CBC and metabolic panel. MRI showed para - vertebral s<strong>of</strong>t tissue densities at T9-<br />

12 bilaterally extending into the neural foramen, bony destructive changes with adjacent sclerosis with<br />

the appearance <strong>of</strong> a chronic infectious process. PPD, HIV, brucella serology, urine histoplasma antigen<br />

and blood cultures were negative. CT guided biopsy <strong>of</strong> the vertebral lesion performed was inconclusive,<br />

with final pathology showing chronic inflammatory changes but negative for malignancy, tuberculosis,<br />

bacterial and fungal infection. T9-T10 laminectomy with epidural space exploration was done, tissue<br />

pathology revealed chronic osteomyelitis. Gram stain <strong>of</strong> the tissue showed gram positive bacilli. Patient<br />

was initially started on intravenous ampicillin for presumed Actinomycoses. Tissue culture grew<br />

Corynebacterium Jeikeium and the patient was treated with intravenous vancomycin for 8 weeks. The<br />

patient responded well and was ambulating with a cane on subsequent follow-up at 2 months.<br />

DISCUSSION: Discussion C. jeikeium is a gram-positive rod that exists as part <strong>of</strong> the normal skin flora,<br />

particularly in the axillary, rectal, and inguinal regions <strong>of</strong> hospitalized patients. Risk factors for C.<br />

jeikeium infection include hematologic malignancy, neutropenia, intravasular catheter, prosthesis<br />

prolonged hospitalization and exposure to multiple antibiotics,. Few cases <strong>of</strong> serious C.jeikeium infection<br />

in patients with no risk factors have been reported. The predominant syndrome associated with C.<br />

jeikeium is sepsis, which can occur in conjunction with pneumonia, endocarditis, meningitis,<br />

osteomyelitis or epidural abscess. Of particular concern is the fact that C. jeikeium is resistant to most<br />

antibiotics tested except for vancomycin and teicoplanin. Effective therapy involves removal <strong>of</strong> the<br />

source <strong>of</strong> infection and long term antibiotic. Conclusion This case emphasizes the importance <strong>of</strong> this<br />

group <strong>of</strong> antibiotic resistant corynebacteria typically known to infect only immunosuppressed patients<br />

as a potential cause <strong>of</strong> serious infection in immunocompetent patients without any associated risk<br />

factors.<br />

Hematological Abnormalities After Bariatric Surgery: More Than Just Iron And Vitamin B12 Deficiency<br />

Kiran Narreddy, MD; Co-Authors: Krishnarao Tangella MD, Sohail Chaudhry MD<br />

INTRODUCTION: Copper (Cu) deficiency is an under diagnosed cause <strong>of</strong> various hematological<br />

abnormalities. It manifests as bicytopenia or pancytopenia. Cu is essential for function <strong>of</strong> numerous<br />

enzymes in the body, including ceruloplasmin, cytochrome c oxidase and copper-zinc superoxide<br />

dismutase. Patients with history <strong>of</strong> bariatric surgery, gastrectomy, small bowel resection, celiac disease<br />

and prolonged total parenteral nutrition are at risk for Cu deficiency. Review <strong>of</strong> the literature showed<br />

only few case series to date. We here report the case <strong>of</strong> 50-year-old female with pancytopenia and<br />

extensive work up finally revealed copper deficiency.<br />

CASE PRESENTATION: A 50-Year-old female presented to the hematology clinic for evaluation <strong>of</strong><br />

pancytopenia. Past medical history significant for bariatric surgery performed one year ago. Complete<br />

blood counts were normal prior to surgery. Examination was negative for lympadenopathy and<br />

organomegaly. Initial labs showed pancytopenia, normal Vitamin b12, folic acid and Iron studies. Bone<br />

marrow biopsy showed hypo cellular marrow (10% cellularity) with no obvious myelodysplasia or<br />

malignancy, adequate iron stores, normal cytogenetics and flow cytometric analysis. Patient was<br />

referred to tertiary care center for further evaluation. Further investigations revealed marked decrease<br />

in serum copper and ceruloplasmin levels. Patient was started on intravenous copper chloride infusions<br />

once a month, which led to remarkable improvement in complete blood counts.<br />

DISCUSSION: The physiology <strong>of</strong> Cu absorption is poorly understood in humans. Copper absorption is<br />

assumed to take place in stomach and proximal small intestine. Copper deficiency also known as<br />

hypocupremia is potentially serious and preventable complication following bariatric surgery. It should<br />

be considered in the differential diagnosis <strong>of</strong> high-risk patients who presents with unexplained<br />

cytopenias. With increase in number <strong>of</strong> bariatric surgeries since last decade, our case report aims to<br />

increase awareness among primary care physicians about the hematological manifestations <strong>of</strong> copper<br />

deficiency. We also emphasize to consider checking serum copper and ceruloplasmin levels during the<br />

initial work up for pancytopenia in high-risk patients.<br />

Streptococcus bovis Bacteremia Associated with Composite Lymphoma<br />

Ahmet Afsin Oktay, MD (ACP Associate); Fritzie Albarillo (ACP Associate), MD; Janis Atkinson, MD<br />

INTRODUCTION: Streptococcus bovis (S. bovis) infections in humans are usually associated with<br />

bacteremia and infective endocarditis (IE). Gastrointestinal tract is the main portal <strong>of</strong> entry for S. bovis.<br />

It has been well known that S. bovis bacteremia, with or without IE, is associated with underlying<br />

malignancy <strong>of</strong> the colon as well as extra-colonic malignancy or liver disease. Every patient with S. bovis<br />

bacteremia should undergo evaluation for IE and gastrointestinal malignancy.<br />

CASE PRESENTATION: An 86-year-old male patient with past medical history <strong>of</strong> mild dementia, deep<br />

vein thrombosis, hypertension, and type-2 diabetes mellitus was admitted for generalized weakness and<br />

asymptomatic hypoglycemia. Family members reported that the patient had been having generalized<br />

weakness, poor appetite and had fallen multiple times recently without loss <strong>of</strong> consciousness. His<br />

medications had included warfarin, metformin and glyburide. When he presented to the ED his vital<br />

signs were within normal limits. On examination he was found to be lethargic, diaphoretic and oriented<br />

only to person and place. Initial laboratory tests were unremarkable except for serum glucose <strong>of</strong> 69<br />

mg/dL. Initial urinalysis showed hematuria without any sign <strong>of</strong> urinary tract infection. Blood cultures and<br />

urine culture from the day <strong>of</strong> admission were negative. On the third day <strong>of</strong> admission he was found to<br />

have severe sepsis. His blood cultures on that day reported S. bovis and Enterococcus faecalis. The<br />

latter also grew in the urine culture. The patient responded well to intravenous Vancomycin and fluid<br />

replacement. An extensive work-up was done to identify the source <strong>of</strong> S. bovis bacteremia. Transesophageal<br />

echocardiography showed no evidence <strong>of</strong> thrombus or vegetation. His colonoscopy showed<br />

a single sessile polyp with no evidence <strong>of</strong> malignancy. CT <strong>of</strong> the chest, abdomen and pelvis showed a 4.2<br />

x 5.6 cm intra-abdominal mass adjacent to the liver and diffuse thoracic, abdominal and pelvic<br />

lymphadenopathy. An incisional biopsy <strong>of</strong> deep cervical/scalene lymph node and immunophenotypic<br />

analysis revealed composite lymphoma: classical Hodgkin’s lymphoma and CD5 positive B-cell<br />

lymphoproliferative disorder.<br />

DISCUSSION: S. bovis bacteremia with underlying lymphoma, mostly gastric lymphoma, was reported<br />

in very few case reports. To our knowledge this is the first S. bovis bacteremia case reported to be<br />

associated with composite lymphoma which is a rare disease and defined by the presence <strong>of</strong> two or<br />

more distinct lymphoma types in a single lymph note. The underlying mechanism for the association<br />

between S. bovis infection and malignancy remains elusive. We believe that, in our case, the liver<br />

involvement has provided a portal <strong>of</strong> entry from the hepatobiliary tree for S. bovis. This case supports<br />

the fact that S. bovis bacteremia cases need extensive workup to rule out underlying malignancy.<br />

To Bleed Or Not To Be: heyde’s Syndrome, A Clinically Under-recognized association Revealed<br />

Tarpan R Patel, MD Second Author: Siegfried Yu, MD<br />

INTRODUCTION: Acute upper gastrointestinal bleeding (GIB) has an incidence <strong>of</strong> 40-120 episodes per<br />

100,000 persons annually and acute lower GIB has an incidence <strong>of</strong> 20-27 episodes per 100,000 persons<br />

annually. 1 There is a significantly increased prevalence <strong>of</strong> aortic stenosis (AS) in patients with<br />

angiodysplasia, a common cause <strong>of</strong> GIB in the elderly. 2,3 We describe a case <strong>of</strong> Heyde’s Syndrome (HS), a<br />

clinically under-recognized association, composed <strong>of</strong> a triad <strong>of</strong> AS, GI bleeding from angiodysplasia, and<br />

acquired coagulopathy. 4<br />

CASE PRESENTATION: A 65 year old male with known Marfan’s Syndrome and aortic valve<br />

replacement (AVR) x 3 presented to the emergency department with progressive weakness, shortness <strong>of</strong><br />

breath, and melena. He had been admitted 10 times in the previous 12 months for GIB. His initial<br />

hemoglobin was 4.5 g/dL, and after stabilization with fluid resuscitation and blood transfusion, he<br />

underwent an urgent upper endoscopy. This revealed brisk, active bleeding from multiple 1-2 mm<br />

arteriovenous malformations (AVM’s) present in the gastric body. The AVM’s were treated with clipping<br />

and injection sclerotherapy.<br />

Due to his AVR history, and the presence <strong>of</strong> a grade 3/6 systolic murmur that did not resolve with<br />

correction <strong>of</strong> his anemia, a diagnosis <strong>of</strong> HS was considered. An echocardiogram revealed severe<br />

bioprostheic valve AS with leaflet calcification and a left ventricular ejection fraction <strong>of</strong> 28%, confirming<br />

the clinical triad needed to make a diagnosis <strong>of</strong> HS. Desmopressin, conjugated estrogens, and octreotide<br />

were added to his management. Due to his persistent problems with frequent, severe GI bleeding,<br />

mesenteric angiography was pursued and demonstrated bleeding from the right gastroepiploic artery,<br />

correlating with the lesions found on endoscopy, and embolization was performed. His hemoglobin<br />

stabilized to 9.1 g/dL, and he was discharged home. At his 2 week follow-up, the patient was<br />

asymptomatic with normal stools and a hemoglobin <strong>of</strong> 10 g/dL AVR was discussed with the patient as a<br />

potential surgical cure, but due to patient’s preferences, non-surgical management was pursued.<br />

DISCUSSION: The association <strong>of</strong> AS and GIB was first described by Heyde in 1958. 5 Although HS as a<br />

true clinical entity has been questioned, 4 more recent studies confirm a direct association between the<br />

severity <strong>of</strong> the valvular disease and coagulopathy. 6 High molecular weight multimers <strong>of</strong> von Willebrand<br />

Factor undergo shear stress-mediated proteolysis due to AS, and this produces an acquired type 2A Von<br />

Willebrand syndrome, which has been demonstrated to improve after AVR in HS. 4,6 This may support<br />

why AS carries an approximate 100-fold increased prevalence <strong>of</strong> GIB, 3,4 and the observation that the<br />

majority <strong>of</strong> patients with HS who undergo AVR stop bleeding. 4 Because the ideal treatment for HS is the<br />

replacement <strong>of</strong> the AV, 4,7 early recognition <strong>of</strong> HS by health care providers may lead to more effective<br />

treatment, and potential cure. 2-4,6<br />

INTRODUCTION: Back pain is the second most common symptom related reason for clinician<br />

visit. Multiple surveys have estimated the prevalence <strong>of</strong> back pain in different populations. In 2002, US<br />

National Health interview Survey showed that 26% <strong>of</strong> people experienced back pain lasting a whole day<br />

for 3 months. In about 85% <strong>of</strong> cases the physiologic cause cannot be estimated. Total cost <strong>of</strong> low back<br />

pain in the US exceeds $100 billion per year. Here is a case report <strong>of</strong> a 49 year old M with an uncommon<br />

etiology <strong>of</strong> low back pain.<br />

CASE PRESENTATION: A 49 year old Caucasian man was admitted for worsening chronic back pain<br />

since 2 months. An outpatient evaluation in the Spine Institute which included MRI <strong>of</strong> the lumbar and<br />

thoracic spine was unremarkable. He was treated with intraarticular steroid injection and opioid<br />

medication without much improvement. Upon admission his hemoglobin was found to be 7.5 g/dl. An<br />

upper endoscopy revealed a large hemorrhagic gastric polyp which was removed. He was transfused<br />

packed red blood cells and discharged home. However, he had recurrent hospitalizations every month<br />

due to persistent back pain and anemia; also, his repeat EGDs were normal. During his fourth<br />

hospitalization (within a 5 month period), a CT chest/abdomen and pelvis revealed splenomegaly as well<br />

as multiple lytic lesions in the right ilium and sacrum. A CT guided biopsy <strong>of</strong> the right ilium<br />

demonstrated renal cancer, clear cell type (Furhman grade 4); however a CT abdomen/pelvis and<br />

ultrasound <strong>of</strong> the abdomen did not reveal any renal mass. The patient underwent palliative radiation to<br />

the spine, however he eventually succumbed to the disease within two weeks following discharge.<br />

DISCUSSION: The incidence <strong>of</strong> renal cell cancer (RCC) has increased by 3.5% in the past<br />

decade. Approximately 10% <strong>of</strong> RCC cases present with the classic triad <strong>of</strong> hematuria, abdominal mass<br />

and pain. Several patients present with symptoms <strong>of</strong> anemia, hepatic dysfunction and<br />

metastasis. About 5% <strong>of</strong> RCC metastasize to the bone and less than 3% <strong>of</strong> them are smaller than 3 cm in<br />

size. Clinicians should have a high level <strong>of</strong> suspicion in patients presenting with non specific symptoms<br />

<strong>of</strong> anemia, weight loss etc. Labaratory testing may be significant in suggesting the presence <strong>of</strong><br />

disseminated disease, such as: anemia, elevated liver function tests, alkaline phosphatase, or increased<br />

calcium. Multiphasic CAT scan is 100% sensitive for detection <strong>of</strong> a mass greater than 15 mm in size. An<br />

early diagnosis may improve morbidity by preventing further complications like Budd-Chiari syndrome,<br />

pulmonary emboli and paraneoplastic manifestations.<br />

INTRODUCTION:Nearly 14 million <strong>American</strong>s have symptomatic coronary artery disease (CAD) and<br />

results in one death every minute. Given this enormous disease burden both patients and physicians<br />

worry <strong>of</strong> potential symptomatic CAD as a cause for chest pain. In such a diagnostic environment there is<br />

an increasing need to be aware <strong>of</strong> non CAD related causes <strong>of</strong> cardiac chest pain<br />

CASE PRESENTATION: : A 77-year-old woman presented to the hospital with mid sternal chest<br />

tightness after an altercation with a family member. Symptoms lasted 30 minutes and were<br />

accompanied by shortness <strong>of</strong> breath, diaphoresis and nausea. She had similar episodes <strong>of</strong> chest<br />

tightness while climbing stairs or under emotional stress. Physical examination was unremarkable. Her<br />

electrocardiogram (EKG) did not reveal changes consistent with cardiac ischemia and was unchanged<br />

from prior EKG. Laboratory evaluation revealed clinically significant elevation in troponin at 1.62 ng/ml<br />

(normal - 0.00-0.04ng/ml). Transthoracic Echocardiogram (TTE) was performed which showed akinesis<br />

<strong>of</strong> the apical and infero-apical segments <strong>of</strong> the myocardium. There was associated moderately<br />

diminished left ventricular systolic function with an ejection fraction <strong>of</strong> 35%. Cardiac catheterization<br />

was performed which showed no evidence <strong>of</strong> flow limiting CAD. This presentation is consistent with<br />

Stress induced cardiomyopathy, where in onset <strong>of</strong> chest pain is usually triggered by emotional stress,<br />

and investigations reveal nonobstructive CAD and apical ballooning <strong>of</strong> the myocardium. The patient was<br />

started on beta blockers and two weeks later a TTE was repeated which now demonstrated complete<br />

reversal <strong>of</strong> findings as compared to the study done two weeks ago. Apical akinesis had resolved and left<br />

ventricular systolic function had improved to normal and was calculated at 72%.<br />

DISCUSSION: Stress induced cardiomyopathy, also known as Tako-tsubo cardiomyopathy, transient<br />

apical ballooning syndrome, or broken-heart-syndrome is a close mimic <strong>of</strong> acute myocardial infarction.<br />

The clinical presentation including, symptoms <strong>of</strong> chest tightness, shortness <strong>of</strong> breath, elevated cardiac<br />

markers and on occasion acute ST and T wave changes on EKG can <strong>of</strong>ten make the distinction between<br />

the two disease entities difficult. The onset <strong>of</strong> symptoms due to stress induced cardiomyopathy is <strong>of</strong>ten<br />

preceded by emotional or physical stress in approximately 66% <strong>of</strong> patients. TTE demonstrates transient<br />

regional wall-motion abnormalities mainly at the apical segment, with a resultant ballooning <strong>of</strong> this<br />

segment in systole relative to the other cardiac regions. Further, echo-graphic abnormalities resolve<br />

within weeks. Percutaneous coronary angiography <strong>of</strong>ten demonstrates non-obstructive coronary artery<br />

disease. The early use <strong>of</strong> coronary angiography as a diagnostic modality will inevitably lead to earlier<br />

recognition and less inappropriate thrombolysis in the predominant elderly population.<br />

A Case Report <strong>of</strong> Apical Hypertrophic Cardiomyopathy Mimicking Acute Coronary Syndrome.<br />

Manish P Shrestha, MD Second Author: Vinod Khatri, MD Third Author: Karoon Nititham, MD Fourth<br />

Author: Harvey Friedman, MD<br />

INTRODUCTION: Apical hypertrophic cardiomyopathy (AHCM) is a form <strong>of</strong> non-obstructive<br />

hypertrophic cardiomyopathy involving the left ventricular apex. Giant T wave inversions in the<br />

precordial leads are the characteristic electrocardiographic findings. Extensive T wave inversions may<br />

also be seen in coronary disease, particularly <strong>of</strong> the proximal left anterior descending artery, Brugada<br />

syndrome, arrythmogenic right ventricular cardiomyopathy, subarachnoid hemorrhage, metabolic<br />

abnormalities including hypocalcemia. Electrocardiographic changes in apical hypertrophic<br />

cardiomyopathy are <strong>of</strong>ten confused with acute coronary syndromes. This may lead to unnecessary<br />

investigation and inappropriate treatment. Invasive or non-invasive evaluation <strong>of</strong> the left ventricular<br />

cavity is required to confirm the diagnosis. Unlike patients with hypertrophic obstructive<br />

cardiomyopathy, patients with AHCM generally have benign outcomes in terms <strong>of</strong> cardiovascular<br />

mortality. Morbid sequelae include diastolic dysfunction, left atrial enlargement with subsequent atrial<br />

fibrillation, apical thrombi, ventricular aneurysms, ventricular arrhythmias, and myocardial infarction.<br />

We present a case <strong>of</strong> apical hypertrophic cardiomyopathy in a Caucasian patient who was initially<br />

diagnosed as acute coronary syndrome due to the findings <strong>of</strong> unexplained T wave inversions in the<br />

anterolateral leads.<br />

CASE PRESENTATION: A 71-year-old Caucasian man with a history <strong>of</strong> hypertension, dyslipidemia<br />

presented to the emergency department with complain <strong>of</strong> epigastric abdominal pain and constipation<br />

for 2 days. Pain was described as intermittent, crampy in nature associated with one episode <strong>of</strong> nonbloody<br />

emesis. He denied any chest pain, shortness <strong>of</strong> breath, palpitation, dizziness/lightheadedness,<br />

diaphoresis, fever/chills. His medications included lisinopril and simvastatin. His vital signs were within<br />

normal limits. The physical examination <strong>of</strong> the patient was unremarkable except for epigastric<br />

tenderness on deep palpation. Lab results (CBC, electrolytes, BUN, Creatinine) were unremarkable.12lead<br />

EKG was performed as a part <strong>of</strong> routine investigation, which showed deep T wave inversions in<br />

anterolateral leads. Cardiac markers were within normal limits. Patient was treated with antiplatelet<br />

agents, beta-blocker and heparin. Cardiology service was consulted for possible acute coronary<br />

syndrome( anterolateral ischemia). Upon review <strong>of</strong> old medical record, similar T wave changes were<br />

seen in older EKG obtained 2 years ago. Stress test (adenosine myoview) done 3 years ago was normal.<br />

Heparin, antiplatelet agents were stopped. Transthoracic echocardiogram was ordered, which showed<br />

severe apical left ventricular hypertrophy. A final diagnosis <strong>of</strong> apical hypertrophic cardiomyopathy was<br />

made.<br />

DISCUSSION: When patients present with unexplained EKG repolarisation abnormalities, the diagnosis<br />

poses a significant challenge. There is a wide differential diagnosis including apical hypertrophic<br />

cardiomyopathy (AHCM). The consequences <strong>of</strong> missed diagnosis for a patient include unnecessary<br />

investigation and inappropriate treatment. It is important to note that AHCM can mimic acute coronary<br />

syndrome (ACS). However, an alternative diagnosis should always be considered in patients found to<br />

have AHCM when symptomatic.<br />

First known case <strong>of</strong> FSGS in association with CML – Is it more than serendipity?<br />

Abhijai Singh, MD<br />

INTRODUCTION: A diverse group <strong>of</strong> glomerular lesions have been described in association with<br />

hematological malignancies especially NHL and CLL. However chronic myeloid leukemia and nephrotic<br />

range proteinuria remain a poorly defined association. We describe the first known case <strong>of</strong> Focal<br />

segmental Glomerulosclerosis associated with CML in a young male.<br />

CASE PRESENTATION: A 44 year old man was admitted with progressive fatigue, shortness <strong>of</strong> breath<br />

and B symptoms. Examination revealed abdominal distension with splenomegaly and pedal edema.<br />

Initial laboratory evaluation was remarkable for leucocytosis (188,500 /mm 3 with 89.9% neutrophils<br />

with no peripheral blasts), anemia and thrombocytopenia. A FISH analysis revealed 97.8% interphase<br />

nuclei containing an atypical BCR/ABL1 fusion signal pattern. A bone marrow biopsy was consistent with<br />

CML with 3 % blasts.<br />

His RFT showed a BUN <strong>of</strong> 9 mg/dl and creatinine <strong>of</strong> 1.2 mg/dl. He had 8.7 gm <strong>of</strong> proteinuria with<br />

urinalysis negative for active sediments. A transjugular kidney biopsy was done due to<br />

thrombocytopenia. On light microscopy, 3/10 glomeruli had widespread glomerular scarring involving ><br />

80% <strong>of</strong> the tuft with a segmental appearance to the involved glomeruli. The tubules were atrophic in<br />

50% <strong>of</strong> the cortex with intersititial fibrosis. Immun<strong>of</strong>luorescence studies were significant for 2+<br />

mesangial deposits <strong>of</strong> IgM. Electron microscopy showed diffuse (75-90%) effacement <strong>of</strong> the foot<br />

processes with normal endothelium and glomerular basement membrane. Kidney biopsy was consistent<br />

with FSGS. Workup for known secondary causes <strong>of</strong> FSGS was negative<br />

He failed initial treatment with Imatinib and was given a trial <strong>of</strong> Dasatinib in combination with<br />

prednisone (1mg/kg). Six months on treatment, he had a partial cytogenetic remission (20% Ph<br />

chromosome positive cells) but persistent proteinuria. Patient had a hematological relapse with blast<br />

crisis (peripheral blasts rapidly increased from 30 to 91%), finally succumbing to his fulminant illness.<br />

DISCUSSION: Six prior cases <strong>of</strong> nephrotic syndrome associated with CML have been reported in<br />

literature so far with 4 having nephrotic syndrome at the time <strong>of</strong> diagnosis. The renal pathologies<br />

described have included MPGN in 3, Membranous glomerulopathy in 2 and MCD in 1 patient. Our<br />

patient represents the first case <strong>of</strong> focal segmental glomerulosclerosis associated with CML.<br />

It is unclear at this point though, what role CML plays in initiation <strong>of</strong> the glomerular injury with<br />

manifestation as nephrotic syndrome. However, response to TKI’s in some instances demonstrates the<br />

implied role <strong>of</strong> PDGF in the pathogenesis.Rat models have aptly demonstrated that PDGF and bFGF are<br />

selective mesangial cell mitogens leading to mesangial cell proliferation and extracellular matrix<br />

accumulation, both harbingers <strong>of</strong> glomerulosclerosis<br />

This case illustrates the first report <strong>of</strong> FSGS in association with CML, however, with insufficient evidence<br />

to either suggest a serendipitous or a causative association.<br />

Collagenomas : Common Skin Manifestation Of Multiple Endocrine Neoplasia Type 1 (Men1)<br />

Naykky Maruquel Singh Ospina, MD Second Author : Evelyn Lacuesta<br />

INTRODUCTION: MEN1 is a rare disorder that affects at least two different endocrine tissues within a<br />

single patient. Most commonly the parathyroid glands, the anterior pituitary, and the pancreatic islets<br />

cells. Skin manifestations, such as collagenomas are common in this patients and can help with the<br />

diagnosis.<br />

CASE PRESENTATION: A 39 year old man presented with recurrent episodes <strong>of</strong> abdominal pain and<br />

nausea for the last three years. He had a history <strong>of</strong> primary hyperparathyroidism (PHP) treated with<br />

parathyroidectomy 9 years before presentation. His examination was unremarkable with the exception<br />

<strong>of</strong> epigastric tenderness and multiple pink round nodules <strong>of</strong> about 5-10 mm distributed diffusely<br />

throughout his skin. His laboratory results were remarkable for a Lipase <strong>of</strong> 3 U/L, Calcium <strong>of</strong> 11 ng/mL<br />

and elevated Parathyroid hormone levels. His CT abdomen revealed a hypervascular lesion in the<br />

pancreas. His Prolactin level was 4700 mcg/L and a MRI <strong>of</strong> the brain showed a pituitary macroadenoma.<br />

The findings <strong>of</strong> PHP, pancreatic tumor and pituitary macroadenoma were consistent with MEN1. His<br />

pancreatic biopsy was consistent with a neuroendocrine tumor and his skin biopsy with collagenoma.<br />

Lastly, DNA analysis showed a heterozygous mutation at intron 6 <strong>of</strong> the 11q13 chromosome.<br />

DISCUSSION: MEN1 is a rare inherited syndrome characterized by the presence <strong>of</strong> hyperplasia and<br />

neoplasia in at least two different endocrine tissues within a single patient. Patients with MEN1 most<br />

<strong>of</strong>ten have tumors <strong>of</strong> the parathyroid glands, the anterior pituitary, and the pancreatic islets cells. The<br />

most common and earliest manifestation <strong>of</strong> MEN1 is (PHP), which occurs in 95% <strong>of</strong> cases. Enteropancreatic<br />

tumors occur in 30%–80% <strong>of</strong> patients and more than 50% secrete gastrin. Anterior pituitary<br />

tumors occur in 15%– 90% <strong>of</strong> patients.<br />

The gene for MEN1 is located on chromosome 11q13. It’s function is unknown, but it is postulated to be<br />

a tumor suppressor gene. Patients found to have a mutated allele characteristic <strong>of</strong> MEN1 are not treated<br />

until there is clinical evidence <strong>of</strong> a characteristic disease.<br />

Our case brings up many interesting points. First, even though he had received definitive treatment for<br />

his PHP it was again active upon admission. This reactivation occurs in about 50 % <strong>of</strong> the patients with<br />

MEN 1. He had multiple pink round nodules on physical exam with histological findings consistent with<br />

collagenomas. Cutaneous tumors are common in patients with MEN 1. Collagenomas are found in 60-70<br />

% <strong>of</strong> the patients. Some authors believe they may help with presymptomatic diagnosis. Lastly, even<br />

though his genetic testing was positive current guidelines recommend against routine screening <strong>of</strong><br />

family members since there is no therapy that can prevent MEN 1 manifestations.<br />

Posterior Reversible Encephalopathy Syndrome Precipitated by an Energy Drink.<br />

Soujanya sodavarapu, MD Girish Singhania, MD JOHN H PULA, MD, BHAGAT S AULAKH, MD MELISSA J<br />

JOOS , NP<br />

INTRODUCTION:PRES is likely caused by transiently impaired cerebrovascular autoregulation.<br />

Hypertensive encephalopathy, eclampsia, and sepsis have been reported as the most common causes.<br />

CASE PRESENTATION: A 36 year old male on fluvoxamine for obsessive-compulsive disorder presented<br />

to the ER with the worst headache <strong>of</strong> his life. According to the patient, he drank a Finaflex N.O. Ignite<br />

pre-workout drink and lifted weights prior to headache onset. His review <strong>of</strong> systems was positive for<br />

nausea, vomiting, and photophobia, and negative for fever, neck stiffness, dizziness, chest pain, or<br />

palpitations. His initial exam showed a blood pressure <strong>of</strong> 172/102, with no focal neurologic deficits or<br />

optic disc edema. He had no history <strong>of</strong> hypertension. After an hour <strong>of</strong> observation in the ER, he vomited,<br />

seized, became obtunded, and exhibited decerebrate posturing. He was intubated and loaded with<br />

levitiracitam. Head CT was unremarkable. CBC, CMP, cardiac enzymes, urinalysis, anti-SM antibody,<br />

SMRNP, SSA, SSB, SCL 70, anti-JO1, and ANA were all essentially normal. Lumbar puncture revealed<br />

WBC-1(0-5/microliter), RBC-95(0/microliter), protein-50(12-60mg/dl), glucose-74(40-70mg/dl), gram<br />

stain-negative. Brain MRI showed abnormal FLAIR signal in the subcortical white matter <strong>of</strong> the supra-<br />

and infratentorial brain with areas <strong>of</strong> diffuse leptomeningeal enhancement. Twenty-four hours after<br />

admission, he recovered to normal mental status and motor function, without further seizures, and was<br />

extubated. His blood pressure normalized without medications. Seventy-two hours after admission, his<br />

neurological exam was normal, and his only symptom was a mild headache. He was discharged on<br />

depakote as a headache reliever, antiepileptic, and mood stabilizer. Two weeks after discharge, repeat<br />

brain MRI showed resolution <strong>of</strong> the previously noted abnormalities. Based on his elevated blood<br />

pressure at admission, presenting brain MRI appearance, and rapid clinical and radiographic<br />

improvement, he was diagnosed with posterior reversible leukoencephalopathy syndrome (PRES).<br />

Analysis <strong>of</strong> the ingredients in his pre-workout energy drink revealed the presence <strong>of</strong> caffeine and<br />

theophylline. Severe drug interactions between fluvoxamine and theophyline have been reported,<br />

including nausea, vomiting and seizures. The energy drink supplement he used can be purchased over<br />

the internet, and advertises that it will “Make it Mind-Blowing” and “The stimulants will IGNITE your<br />

workout and light you up”.<br />

DISCUSSION: Our patient’s presentation is consistent with hypertension-induced PRES. What is novel<br />

about our patient is that his elevated blood pressure was likely due to a pharmacological interaction<br />

between two medications which had been previously reported as causing similar symptoms to PRES.<br />

Although we have no data regarding prior cases, it is possible that the previously reported interactions<br />

between theophyline and fluvoxamine <strong>of</strong> hypertension, seizure, and vomiting actually represented<br />

hypertension-induced PRES. We highlight that PRES should be considered in cases <strong>of</strong> seizure and<br />

encephalopathy, even without a typical predisposing cause, so proper treatment can be provided.<br />

Though it sounded infectious<br />

Muhammad Toor, MD Second Author: Sarvanan Pathanjali, MD Third Author: Danish Thameem, MD<br />

INTRODUCTION:Most people will experience at least a single episode <strong>of</strong> backache in their life. While<br />

such pain or discomfort can occur at any point in the back, the most common area affected remains to<br />

be the lower back. Backache associated with fever includes a list <strong>of</strong> differentials which need to be<br />

considered. Among these, infectious causes are particularly important due to high mortality.<br />

CASE PRESENTATION: A 22-year old Caucasian gentleman was referred for the evaluation <strong>of</strong> a 5-day<br />

history <strong>of</strong> non traumatic low back pain and fever. Backache was acute in onset, non radiating, dull in<br />

character and <strong>of</strong> 4/10 in intensity. The pain increased with raising the lower extremities in supine<br />

position. Fever was low grade and associated with night sweats. He was a non-smoker with no other comorbidities.<br />

Physical examination revealed mild tenderness in the lower para-spinal region and no<br />

neurological deficits. Laboratory data was unremarkable except white blood count (WBC) <strong>of</strong> 11100/ul,<br />

C- reactive protein (CRP) <strong>of</strong> 177 mg/l and erythrocyte sedimentation rate (ESR) <strong>of</strong> 53 mm/hr.<br />

Radiological investigations were unremarkable for any abscess or lymphadenopathy. MRI<br />

abdomen/pelvis with contrast revealed thrombosis in the inferior vena cava and common iliac veins.<br />

Widespread inflammatory changes surrounding these venous structures were compatible with acute<br />

thrombophlebitis. A striking finding was an interrupted inferior vena cava and multiple collaterals<br />

draining into supra hepatic circulation. The patient was started on anticoagulation with subcutaneous<br />

enoxaparin. He was given no antibiotics and his urine and blood cultures were negative. His symptoms<br />

resolved on anticoagulation and he was discharged on warfarin.<br />

DISCUSSION: Absent inferior vena cava is a rare anomaly present in 0.3% <strong>of</strong> otherwise healthy<br />

individuals. it is associated with idiopathic deep venous thrombosis, particularly in the young. Review <strong>of</strong><br />

the literature revealed that fever along with elevated inflammatory markers (WBC, ESR, and CRP) is a<br />

common presentation. Computed tomography or preferably magnetic resonance imaging, are required<br />

to delineate inferior vena cava anatomy and ascertain proximal extent <strong>of</strong> the thrombus. Although<br />

invasive therapeutic modalities exist, long-term and commonly life-long anticoagulation is <strong>of</strong>ten<br />

required.<br />

A rare cause <strong>of</strong> acute mastitis.<br />

Muhammad Toor, MD Second Author: James Kumar, MD<br />

INTRODUCTION:Mastitis is the inflammation <strong>of</strong> breast tissue that may or may not be infectious in<br />

etiology. Infectious mastitis is most commonly seen in lactating women. Though uncommon in nonlactating<br />

women, streptococcus, pseudomonas and staphylococcus remain the main infectious causes.<br />

When non-lactational mastitis does not respond to antibiotic therapy physicians should look for the<br />

other causes like atypical infections or malignancy.<br />

CASE PRESENTATION: A 50 year old female presented to the primary care physician <strong>of</strong>fice with the<br />

complaints <strong>of</strong> left breast pain, redness and nipple discharge <strong>of</strong> 5-days duration. She was also<br />

experiencing upper respiratory tract symptoms at the same time. Nipple discharge was cultured and she<br />

was empirically started on azithromycin for upper respiratory tract symptoms. Over the course <strong>of</strong> next<br />

two days, upper respiratory symptoms resolved but her breast pain and redness increased and extended<br />

towards axilla. She presented to the emergency department with these complaints and was admitted<br />

for administration <strong>of</strong> intravenous antibiotics and evaluation <strong>of</strong> non-resolving mastitis. After collection <strong>of</strong><br />

appropriate cultures intravenous vancomycin and intravenous metronidazole were started. Nipple<br />

discharge cultures drawn as an outpatient did not grow anything in three days. USG <strong>of</strong> the breast was<br />

negative for any abscess but showed multiple mildly dilated ductal structures in the subareolar and<br />

periareolar region. Many <strong>of</strong> these ducts showed debris without any evidence <strong>of</strong> mass. These findings<br />

were consistent with acute mastitis. With minimal improvement patient was discharged to home on oral<br />

doxycycline and metronidazole with an outpatient follow-up. However over next two days, her<br />

symptoms did not improve with oral antibiotics. On follow up, history was reviewed again and she gave<br />

the positive history <strong>of</strong> cold sores in her husband. At that time, her antibiotics were stopped and oral<br />

acyclovir was started suspecting mastitis to be <strong>of</strong> viral etiologies. Nipple discharge was obtained for viral<br />

cultures. Her symptoms improved dramatically with this treatment and later cultures were reported to<br />

be positive for herpes simplex virus type 1.<br />

DISCUSSION: Herpes mastitis in non-lactating women is an extremely rare condition and it should be<br />

suspected in the cases not responding to antibiotics. Only few cases have been reported so far in<br />

literature. Exact mode <strong>of</strong> transmission is unclear though possible modes include autoinoculation from<br />

the oral or genital lesions and transmission from close personal contact. In our case herpes was probably<br />

transmitted from the close contact. Herpes mastitis should be considered in non-lactating women with<br />

non-resolving mastitis and careful history focusing on the possible modes <strong>of</strong> transmission should be<br />

obtained.<br />

Hyperbaric Oxygen as a treatment option for Diabetic Myonecrosis<br />

Malvika Varma, MD Tanvi Tiwari, MD Sunitha Nair, MD<br />

INTRODUCTION: Diagnosing Diabetic Myonecrosis<br />

CASE PRESENTATION: 31 year old female with type 1 diabetes mellitus presented with pain and<br />

swelling <strong>of</strong> the right medial thigh since two weeks. There was no history <strong>of</strong> fever, trauma, joint pain,<br />

joint stiffness or sensory loss. She had a similar episode two years ago involving both calf muscles<br />

treated with rest and analgesics and took several months to resolve.<br />

Past medical history was significant for type 1 diabetes, Grave’s disease, thyroid carcinoma post<br />

thyroidectomy, and post-surgical hypothyroidism. She was non compliant with her medications which<br />

included levothyroxine, NPH insulin and Lisinopril. Clinical examination was significant for low grade<br />

fever and sinus tachycardia. Right lower extremity was edematous and extremely tender without<br />

erythema or crepitus. The lower medial thigh was most tender without any fluctuant mass. There was<br />

no swelling or stiffness <strong>of</strong> the knee and distal neurovascular function was intact. Muscle strength was<br />

difficult to assess proximally due to severe pain but was normal distally.<br />

Labs were remarkable for a mildly elevated white count, microcytic iron deficiency anemia and normal<br />

renal function. Thyroid stimulating hormone was 105.6 and free T4 was 0.675. Total creatine kinase was<br />

309. Glycated hemoglobin was 10.8%. Urine microalbumin to creatinine ratio was 330.7 suggestive <strong>of</strong><br />

occult nephropathy. Hypercoaguable workup was positive for lupus anticoagulant. ANA panel was<br />

negative.<br />

CT scan showed massive intramuscular, subcutaneous and fascial edema <strong>of</strong> vastus musculature<br />

specially vastus medialis. Arterial and venous dopplers <strong>of</strong> the lower extremities were negative for DVT<br />

and arterial occlusion.<br />

She was initially treated with intravenous antibiotics, opioid analgesics. MRI done 48 hours later<br />

confirmed the CT findings and now showed edema extending proximally into the pelvic muscles and<br />

distally into the calf muscles. Needle biopsy <strong>of</strong> vastus medialis revealed acute inflammation and<br />

hemorrhagic necrosis <strong>of</strong> the skeletal muscle consistent with diabetic muscle infarction(DMI) and she was<br />

started on NSAIDs and aspirin.<br />

A trial <strong>of</strong> daily hyperbaric oxygen treatment (HBOT) at 2.5 atmospheres absolute (ATA) was started after<br />

informed consent. By the fourth treatment her symptoms were reduced by 50% and she was discharged<br />

on day ten after 5 HBOTs, with remaining treatments scheduled as outpatient. Patient’s recovery was<br />

gauged by symptomatic improvement.<br />

DISCUSSION: DMI is a rare and under recognized complication <strong>of</strong> diabetes mellitus, characterized by<br />

localized acutely painful inflammation and necrosis <strong>of</strong> muscles involving the extremities. It is typically<br />

associated with long standing poorly controlled diabetes type1. Pathogenesis <strong>of</strong> the condition remains<br />

unclear but largely involves muscle ischemia secondary to diabetic vasculopathy. Since the underlying<br />

process in diabetic myonecrosis involves tissue ischemia, HBO could possibly play a crucial role in its<br />

treatment.<br />

This time, the heart is really broken.<br />

Rahul Wadke, MBBS, Bihn An Phan MD FACC<br />

INTRODUCTION: Takotsubo cardiomyopathy (TTC), also known as stress induced cardiomyopathy or<br />

apical ballooning syndrome or broken heart syndrome, is described in literature since 1990. It tends to<br />

mimic acute coronary syndrome and most commonly presents as acute sub-sternal chest pain. The<br />

diagnosis <strong>of</strong> TTC should be suspected in postmenopausal woman with chest pain, nonspecific ECG<br />

changes, troponin elevation, cardiac imaging demonstrating apical ballooning, and absence <strong>of</strong><br />

obstructive CAD on angiography. Psychosocial or physical stressor typically precedes the development<br />

<strong>of</strong> TTC. Despite its severity <strong>of</strong> presentation, majority <strong>of</strong> patients tend to have a favorable outcome.<br />

CASE PRESENTATION: 85 year old female presented to emergency room with substernal chest pain<br />

and acute onset shortness <strong>of</strong> breath from inpatient rehabilitation facility. She suffered an ischemic<br />

stroke 4 weeks ago. On presentation she was hypoxic and hypertensive. Physical examination revealed<br />

elevated JVD, crisp S1 & S2, no murmurs, and inspiratory crackles bilateral lung fields. 12 lead ECG<br />

revealed normal sinus rhythm without ST segment alteration with elevation <strong>of</strong> troponin I levels. Medical<br />

management was initiated for non ST elevation MI (NSTEMI). Hypoxia rapidly improved with Bipap.<br />

With increasing cardiac markers and a new wall motion abnormality on transthoracic echocardiogram<br />

(TTE), patient underwent cardiac catheterization. It revealed left ventricular ejection fraction (LVEF) <strong>of</strong><br />

55% with apical ballooning, and nonobstructive coronary artery disease. She was diagnosed with TTC.<br />

After a day <strong>of</strong> improvement, patient had an episode <strong>of</strong> syncope, hypotension and hypoxia. She was<br />

intubated for persistent hypoxia. Physical examination revealed a new III/VI holosystolic murmur at apex<br />

radiating to axilla, elevation <strong>of</strong> JVD, and fine crackles across entire lung field. ECG remained essentially<br />

unchanged. Cardiogenic shock required inotropic agents to maintain blood pressure. Pulmonary<br />

embolism was ruled out as a cause <strong>of</strong> sudden decompensation, with CT chest . Emergency TTE revealed<br />

LVEF <strong>of</strong> 65%, severely flail anterior mitral leaflet with ruptured chordae with severe mitral regurgitation.<br />

These TTE findings were significantly different compared to previous TTE.<br />

With multiple comorbidities, she was recognized as an extremely high risk surgical candidate for mitral<br />

valve replacement. After discussion with cardiologist, cardiothoracic surgeon; patient’s family opted for<br />

comfort care measures. Patient passed away peacefully with her close family by her side.<br />

DISCUSSION: Even though mitral valve regurgitation (MR) is well documented with TTC, acute severe<br />

MR secondary to chordae rupture has rarely been reported in the literature. This case represents an<br />

opportunity to highlight rare but catastrophic complication in patient with TTC. A high level <strong>of</strong> suspicion<br />

in patients with TTC who acutely decompensate will help in rapid diagnosis and possibly better<br />

outcome. The exact mechanism <strong>of</strong> such a catastrophic complication still eludes us.<br />

A rare case <strong>of</strong> Castleman’s disease in a patient with Sjögren’s Syndrome<br />

Muralidhar Reddy Yerramadha, MD Correspondent author: S. Subramanian MD<br />

INTRODUCTION:Castleman's disease, also known as angio follicular lymph node hyperplasia, is a rare<br />

disorder. Castleman's disease is characterized by non-cancerous atypical lympho proliferation with two<br />

types <strong>of</strong> presentation - unicentric and multicentric form. Unicentric Castleman's disease (UCD) presents<br />

as a localized slowly growing mass with a relatively benign course where as multicentric Castleman's<br />

disease (MCD) acts like lymphoma with more aggressive clinical course with diffuse lymph node<br />

enlargement and systemic illness. It involves hyper proliferation <strong>of</strong> specific B cells that produce the<br />

cytokine IL-6.<br />

CASE PRESENTATION: A 47-year-old African <strong>American</strong> woman with known history <strong>of</strong> primary Sjögren's<br />

syndrome diagnosed in 1993 and degenerative arthritis was admitted to our hospital for evaluation <strong>of</strong><br />

shortness <strong>of</strong> breath. Her previous history was significant for extensive recurrent lymph nodal<br />

enlargement including cervical, mediastinal, and abdominal lymph nodes since 1995. Several <strong>of</strong> these<br />

nodes have been biopsied with varying success. Pathology results showed reactive lymphadenopathy<br />

with non specific findings. On current admission CT <strong>of</strong> the chest and abdomen revealed mediastinal<br />

lymph adenopathy and a right perineprhic mass. Later, she underwent laparoscopic excision <strong>of</strong> the<br />

perinephric mass, which was consistent with previous biopsy results. Immuno histochemical staining<br />

revealed no monoclonal lymphocytes suggestive <strong>of</strong> lymphoma. As a result, a plan was made to follow up<br />

in hematology clinic. Over the course <strong>of</strong> 6 months her performance status deteriorated, with worsening<br />

shortness <strong>of</strong> breath, night sweats, weight loss, generalized body pains, and also left hip pain. MRI <strong>of</strong> the<br />

hip showed significant bilateral iliac lymphadenopathy. Her CBC, BMP, Coombs, Immunoglobulin levels<br />

and LDH were normal except elevated IL-6 levels. Later, her biopsy results from right iliac nodes<br />

confirmed the diagnosis <strong>of</strong> hyaline vascular variant <strong>of</strong> MCD. She was started on chemotherapy and<br />

prednisone every three weeks for four cycles. She responded very well to the treatment with<br />

improvement in her performance status.<br />

DISCUSSION: MCD is commonly associated with the human immunodeficiency virus and human<br />

herpesvirus 8, and malignancies including Kaposi's sarcoma, non-Hodgkin lymphoma, Hodgkin<br />

lymphoma, and POEMS syndrome where as in this case we discussed a very rare presentation <strong>of</strong> MCD<br />

associated with Sjögren's syndrome. Most patients with MCD die <strong>of</strong> fulminant infections due to<br />

immunosuppression, progressive disease or related malignancies. There is currently no standard therapy<br />

for MCD. Castleman's disease is <strong>of</strong>ten undiagnosed or misdiagnosed. For this reason, only very few<br />

patients have been reported and little information is available in the literature. It is important to<br />

consider Castleman's disease in the differential when evaluating recurrent lymphadenopathy, as MCD if<br />

left untreated usually gets worse and becomesincreasingly difficult and unresponsive to current<br />

treatment regimens.<br />

Neuropsychiatric Sequelae <strong>of</strong> Hypoparathyroidism: A Case Report<br />

Ben Tritle MD<br />

INTRODUCTION: Intracranial calcification, particularly <strong>of</strong> the basal ganglia and cerebellar nuclei, is a<br />

well documented complication <strong>of</strong> chronic idiopathic hypoparathyroidism. Importantly, these<br />

calcifications can lead to neuropsychiatric manifestations such as movement disorders, delirium or<br />

dementia, psychoses, and less commonly focal neurologic defects or seizure activity.<br />

CASE PRESENTATION: A 55-year-old female patient with long standing history <strong>of</strong> idiopathic<br />

hypoparathyroidism treated with calcitriol and unspecified dementia presented with acutely altered<br />

mental status. Examination revealed a confused and disoriented patient, but no focal neurologic<br />

abnormalities. Laboratory evaluation revealed a calcium level <strong>of</strong> 16.3 mg/dl and ionized calcium <strong>of</strong> 2.23<br />

mmol/L. Head CT revealed symmetric, coarse calcifications within the basal ganglia, periventricular and<br />

frontal lobe white matter, and cerebellar hemispheres. Correction <strong>of</strong> the patient’s serum calcium level<br />

lead to improvement in her mental status back to her baseline dementia. Further investigation into the<br />

medical record revealed this was the patient’s third admission in six months for severe hypercalcemia, in<br />

addition to several episodes <strong>of</strong> pr<strong>of</strong>ound hypocalcemia prior to that. Psychiatric evaluation under<br />

normocalcemic conditions revealed the presence <strong>of</strong> auditory and visual hallucinations, episodes <strong>of</strong><br />

inappropriate laughter, and dementia. After psychiatric evaluation and discussion with family members,<br />

it was determined that the patient’s dementia was advanced to such a degree that she was no longer<br />

capable <strong>of</strong> complying with her calcitriol regimen, and arrangements were made to ensure proper<br />

medication administration.<br />

DISCUSSION: Here we present a case <strong>of</strong> a patient with a long-standing history <strong>of</strong> idiopathic<br />

hypoparathyroidism with extensive intracranial calcification and neuropsychiatric<br />

symptoms. Furthermore, evidence exists within the literature to suggest that presence <strong>of</strong> such<br />

neuropsychiatric symptoms is directly related to the degree <strong>of</strong> intracranial calcification, which can be a<br />

progressive phenomenon despite adequate control <strong>of</strong> serum calcium and phosphorous<br />

levels 1,2 . Coupling that evidence with the report featured above, this case illustrates the necessity for<br />

clinicians to be highly vigilant <strong>of</strong> the cognitive status in patients with idiopathic hypoparathyroidism<br />

when prescribing vitamin replacements that, if taken incorrectly, can lead to severe metabolic<br />

abnormalities.<br />

SKIN RASH NINE YEARS AFTER RENAL TRANSPLANTATION<br />

Jacques Daoud, MD, MS, Vera Marie Rosado-Odom, MD, Asif Sharfuddin MD, FASN, Raymond Johnson,<br />

MD, PhD.<br />

INTRODUCTION: In immunocompromised patients, a high index <strong>of</strong> suspicion is required in order to<br />

identify diseases with atypical manifestations, as they can carry a high mortality rate if the diagnosis is<br />

delayed or missed.<br />

CASE PRESENTATION: A 42-year-old woman presented with a skin rash that started with a tender,<br />

warm and erythematous nodule on her left thigh, and enlarged over the next 2 weeks, associated with<br />

night sweats and a mild dry cough. She denied any recent travel, animal or bird exposure or new sexual<br />

encounters. Her past medical history was significant for bronchial asthma and congenital dysmorphic<br />

kidneys. Having received a deceased donor kidney transplant 9 years ago, her induction therapy<br />

consisted <strong>of</strong> anti-thymocyte globulin, and her early post-transplant period was remarkable for two<br />

rejection episodes. Her maintenance immunosuppression (IS) was cyclosporine, mycophenolate m<strong>of</strong>etil<br />

and prednisone. Physical examination revealed a low grade fever, clear breath sounds, and mild graft<br />

tenderness to deep palpation. An erythematous, nodular rash was noted on the thighs, knees, and right<br />

forearm. The hospital course was complicated with shortness <strong>of</strong> breath and hypoxia that responded to<br />

oxygenation and bronchodilators. Plain chest radiograph was unremarkable, while a chest CT revealed<br />

numerous subcentimeter mediastinal nodes. A punch-skin biopsy from one <strong>of</strong> the newer migratory<br />

lesions revealed yeast forms in the dermis suggestive <strong>of</strong> Histoplasma, confirmed by a positive urinary<br />

Histoplasma antigen. The immuknow ATP assay value was very low in favor <strong>of</strong> pr<strong>of</strong>ound<br />

immunosuppression. Intravenous voriconazole was started followed by oral itraconazole. Three months<br />

later, all cutaneous lesions had disappeared, and the cough had resolved.<br />

DISCUSSION: Skin lesions are a very rare form <strong>of</strong> initial presentation <strong>of</strong> disseminated histoplasmosis.<br />

Such manifestation may lead to misdiagnosis <strong>of</strong> a potentially fatal, otherwise treatable disease. The skin<br />

biopsy helped quickly diagnose this disease, while IS was maximally reduced, and adequate levels <strong>of</strong><br />

antifungals ensured.<br />

What? No Ascending Paralysis?<br />

Joseph Khalil, MD Second Author: Frank Hrisomalos, MD<br />

INTRODUCTION:Guillain-Barre syndrome should be categorized as a group <strong>of</strong> syndromes with several<br />

distinct subtypes. The common presentation <strong>of</strong> ascending paralysis is not essential for diagnosis and<br />

may not even be present in a substantial proportion <strong>of</strong> patients.<br />

CASE PRESENTATION: A 53-year-old male presented with a constellation <strong>of</strong> neurologic symptoms<br />

following an acute giardial diarrheal illness treated with flagyl. Recent history included extensive<br />

camping in Colorado and Kentucky, spring water ingestion, and multiple mosquito bites. Notable<br />

findings included generalized weakness, hyporeflexia, severe lower back pain, bilateral posterior leg and<br />

hand pains and paresthesias, perioral numbness, and dysautonomia including constipation, urinary<br />

retention, and hypertension. Differential diagnosis was wide given this unique history and nonspecific<br />

pattern <strong>of</strong> findings. Among the many conditions considered were an acute neurological process, acute<br />

infectious process, flagyl toxicity, vitamin deficiency, and rare toxic exposure. A decision was made to<br />

perform MR imaging <strong>of</strong> the CNS, lumbar puncture, electromyography, as well as obtain comprehensive<br />

serum studies.<br />

CSF studies revealed an albuminocytologic dissociation with a protein <strong>of</strong> 500 and a WBC <strong>of</strong> 10. EMG<br />

showed prolonged distal latencies and slowed conduction. MRI showed enhancement <strong>of</strong> virtually all<br />

exiting nerve roots <strong>of</strong> the thoracic spine as well as the cauda equina and conus medullaris. All viral<br />

serologies and other serum assays were negative. We concluded that the patient displayed an atypical<br />

presentation <strong>of</strong> Guillain-Barre syndrome. Notably, his autonomic instability and extremity<br />

pains/paresthesias, classify his disease as a mixture <strong>of</strong> pure sensory and dysautonomic subtypes. The<br />

patient’s symptoms improved with 5 days <strong>of</strong> IVIG. Symptoms were controlled and daily incentive<br />

spirometry was performed. The patient’s respiratory status remained stable over admission without<br />

need for respiratory support.<br />

DISCUSSION: Our patient’s atypical presentation provides insight into the heterogeneity <strong>of</strong> this disease<br />

and resulting diagnostic challenges that may arise. It is essential to recognize that Guillain-Barre<br />

syndrome may <strong>of</strong>ten present without classic symptoms <strong>of</strong> ascending paralysis and areflexia. The astute<br />

clinician must combine information gleaned from neuroimaging, electromyography, CSF and serum<br />

studies, as well as a thorough history to diagnose the disease and rule out other possibilities within a<br />

short time frame. Institution <strong>of</strong> Guillain-Barre specific treatment with IVIG or plasma exchange must be<br />

done rapidly to minimize short term morbidity.<br />

Crohn’s Disease and Shock in the Intensive Care Unit<br />

Kapil A Mehta, MD, Mitchell Smith, MD; Andrew Williams, MD<br />

INTRODUCTION: We present a case <strong>of</strong> a 29 year old female with history <strong>of</strong> Crohn’s disease on<br />

azathioprine for 7 years who presented with flu-like symptoms for two weeks. Symptoms included<br />

muscle and joint aches along with nausea and diarrhea. Her husband had experienced similar symptoms<br />

during the same period <strong>of</strong> time; however, his symptoms resolved within a few days and her symptoms<br />

continued. She became increasingly weak, developed a nonproductive cough and continued to have<br />

fevers as high as 102.3F. One week prior to hospitalization, our patient was treated with clarithromycin<br />

for her symptoms. This was followed by extremely watery diarrhea, and fevers. Upon presentation to<br />

our hospital, she was in shock, delirious and admitted to the ICU.<br />

CASE PRESENTATION: Physical exam revealed tachypnea, clear lung fields and a regular tachycardia,<br />

without murmurs, rubs or gallops. No jugular venous distension was present. Non-pitting edema <strong>of</strong> her<br />

bilateral lower extremities was noted. Palpation <strong>of</strong> the abdomen revealed a diffusely tender abdomen<br />

with hepatosplenomegaly, voluntary guarding without rebound. There was presence <strong>of</strong> a diffuse<br />

blanchable, maculopapular rash.<br />

Pertinent laboratory evaluation showed: white blood count <strong>of</strong> 1.5 k/cumm, hemoglobin 8.7 g/dl and<br />

platelet count <strong>of</strong> 59 K/CUMM, ANC was 900 k/cumm with 17% bands. Her LDH 1112 units/L,<br />

Painful, circular pretibial bumps: a case <strong>of</strong> post-streptococcal pharyngitis associated with erythema<br />

nodosum.<br />

Matthew M Nobari, MD Second Author: Nisha Sheth, MD Attending Author: Lannie Cation, MD<br />

INTRODUCTION: A 30 year-old otherwise healthy Hispanic female presented to the clinic with a chief<br />

complaint <strong>of</strong> bilateral lower extremity pain and rash for four days. One week prior to presentation, our<br />

patient had a sore throat with no associated cough. About four days prior to presentation, she had an<br />

abrupt development <strong>of</strong> pretibial pain and swelling bilaterally.<br />

CASE PRESENTATION: On exam, this patient had no oropharyngeal abnormalities, including erythema<br />

or purulent drainage and no adenopathy. On assessment <strong>of</strong> her lower extremities, erythematous<br />

nodular lesions were noted. These lesions were circular, symmetrical and papulo-nodular, and some<br />

were as large as three centimeters in diameter (photos available). They were exquisitely tender to<br />

palpation and no discharge or fluctuance was noted. Laboratory testing obtained the same day revealed<br />

an elevated erythrocyte sedimentation rate <strong>of</strong> 124 (0-20), an elevated anti-streptolysin O titer <strong>of</strong> 205 (0-<br />

200), and a normal angiontensin-converting enzyme level <strong>of</strong> 41 (9-67). A chest-x ray was obtained,<br />

which demonstrated no abnormal findings. Given her history <strong>of</strong> sore throat and elevated ASO titer, we<br />

made a diagnosis <strong>of</strong> recent pharyngeal streptococcus infection with the delayed dermatologic<br />

manifestation <strong>of</strong> erythema nodusum (EN).<br />

DISCUSSION: Treatment for our patient consisted <strong>of</strong> non-steroidal anti-inflammatory drugs. Discussion<br />

with an infectious disease specialist was done, and recommendations were to continue supportive care<br />

with no antibiotic intervention for her resolved streptococcal infection. Her dermatologic lesions<br />

resolved within one week.<br />

Erythema nodosum is the most common form <strong>of</strong> panniculitis. The peak incidence <strong>of</strong> EN occurs between<br />

18-36 years <strong>of</strong> age. Women are 3-6 times more likely to be affected than men. It is a rare dermatologic<br />

finding sometimes associated with various disorders for which the specific pathophysiology remains<br />

unknown. Examples <strong>of</strong> associated disorders include inflammatory bowel disease, sarcoidosis, Behçet’s<br />

disease, drugs and various infections—with post-streptococcal infection being the most<br />

common. Often, no cause is identified. Treatment is symptomatic and directed at the underlying<br />

disease. We report a classic case <strong>of</strong> erythema nodosum associated with recent pharyngeal<br />

streptococcus infection.<br />

Complex Cranial Neuropathy Masquerading as Bell’s Palsy<br />

Andrew J Williams, MD<br />

INTRODUCTION: Bell’s Palsy affects the seventh cranial nerve alone, and true Bell’s remains idiopathic.<br />

Other etiologies <strong>of</strong> seventh nerve palsy are not uncommon and may include more extensive pathology<br />

including central lesions from ischemic disease or masses.<br />

CASE PRESENTATION: An 81-year-old male presented to our Emergency Department with a threemonth<br />

history <strong>of</strong> recurrent otitis media, managed conservatively and three weeks <strong>of</strong> right-sided facial<br />

paralysis. Previous evaluation diagnosed Bell’s Palsy and he was treated with oral prednisone and<br />

acyclovir. With worsening cough and no resolution <strong>of</strong> facial paralysis, he was re-evaluated.<br />

Initial examination revealed a thin male with right facial paralysis. Further neurologic examination<br />

revealed complex cranial nerve involvement including inability to wrinkle his forehead, absence <strong>of</strong> right<br />

nasolabial fold, and facial droop on the right with inability to smile; all concerning for a lower facial<br />

nerve lesion. Other right-sided findings included: trismus, decreased sensation in the trigeminal nerve<br />

distribution, decreased corneal reflex, hearing loss indicating vestibulocochlear involvement, dysphagia<br />

and inability to elevate the hemipalate, indicating compromise <strong>of</strong> the vagal nerve. He was unable to fully<br />

shrug his right shoulder and had weakness turning his head, indicating involvement <strong>of</strong> the accessory<br />

nerve as well. Other neurologic examination revealed no gross strength, tone or reflex abnormalities.<br />

A non-contrast head CT was performed and demonstrated right mastoiditis but lacked details to fully<br />

explain his cranial nerve involvement. Therefore, an MRI with focus on the internal auditory canals and<br />

skull base was obtained. An extensive tumor involving the right aspect <strong>of</strong> the clivus bone, encasement <strong>of</strong><br />

the carotid and jugular vasculature at the jugular foramen, encasement <strong>of</strong> the right styloid process and<br />

involvement <strong>of</strong> the hypoglossal canal was noted. Other imaging <strong>of</strong> his chest, abdomen and pelvis found<br />

no evidence <strong>of</strong> metastatic disease. Differential diagnosis included head and neck cancers,<br />

nasopharyngeal carcinoma, schwannoma, parotid tumor or lymphoma. Biopsy illustrated squamous cell<br />

carcinoma.<br />

DISCUSSION: Squamous cell carcinoma <strong>of</strong> the head and neck carries a poor prognosis and is<br />

traditionally treated with surgical resection; however, skull base involvement, as seen in this case, is a<br />

contraindication for attempted surgical intervention. Two-year survival rates with chemotherapy and<br />

radiation outperform resection but survival is significantly reduced after two years. The patient’s<br />

comorbidities limited his tolerance <strong>of</strong> chemotherapy and he was <strong>of</strong>fered radiation alone.<br />

True Bell’s Palsy is idiopathic. Recurrent, chronic otitis media or mastoiditis can cause a facial nerve<br />

paralysis; however, this case revealed more complex cranial nerve involvement caused by a locally<br />

invasive squamous cell carcinoma. For the general internist, this case emphasizes an appreciation and<br />

skill <strong>of</strong> the physical examination remains the most important tool in their armamentarium.<br />

Hemophagocytic Lymphohistiocytosis Treated Without Immunosuppression<br />

Nicholas L Hartog, MD Other Authors: Hilary Mosher, MD; Zuhair Ballas, MD<br />

INTRODUCTION:Hemophagocytic lymphohistiocytosis (HLH) is an <strong>of</strong>ten-fatal immunologic disease that<br />

can be primary (definitive genetic mutation) or secondary. Secondary HLH is a heterogeneous<br />

disease. Viral infections are known triggers for either form. Other documented triggers <strong>of</strong> secondary<br />

HLH are malignancy, autoimmune disease, infections, and drugs. HLH is a disease <strong>of</strong> dysregulated<br />

immune activation. While primary HLH is treated based on the HLH-2004 protocol, there is currently no<br />

consensus on treatment <strong>of</strong> secondary HLH. We present an immunocompetent patient with HLH<br />

secondary to disseminated CMV successfully treated with valganciclovir.<br />

CASE PRESENTATION: A 24 year-old African <strong>American</strong> male presented with 2 weeks <strong>of</strong> fever,<br />

headaches, loose stool, and abdominal pain. Prior to onset <strong>of</strong> symptoms, he had been on a local<br />

camping trip. Physical exam was significant only for a mildly tender abdomen, worst in the right upper<br />

quadrant (RUQ). Admission workup included normal CSF studies, negative viral hepatitis panel, and an<br />

abdominal CT and RUQ ultrasound notable for mild hepatomegaly. Labs on admission revealed elevated<br />

AST/ALT (67 and 82 U/L respectively) and LDH (576 U/L). A thorough infectious disease workup,<br />

including HIV qualitative and quantitative PCR, was negative. Patient was initially started on doxycycline<br />

for concern for tick borne infections. On day 7, laboratory results revealed a CMV PCR that was 240,000<br />

copies/mL and further worsening <strong>of</strong> liver function. The patient was also found to have nephrotic<br />

syndrome without acute renal failure. Renal biopsy was consistent with minimal change disease. The<br />

patients subsequent clinical decline lead to us reconsidering the diagnosis and current<br />

treatment. Because <strong>of</strong> this decline with worsening hepatits, HLH was considered and serum ferritin<br />

measured; it was elevated at 4179 ng/ml. Valganciclovir was initiated on day 8 <strong>of</strong> hospitalization.<br />

Subsequent HLH-directed testing revealed hypertrigleridemia, elelvated soluble CD25, normal Natural<br />

Killer (NK) cell activity and IL-1ra elevated at 5854 (normal

Chronic Cannabis Use With Hyperemesis, Epigastric Pain And Conditioned Showering Behavior: A Case<br />

Series<br />

Karim Richard Masri, M.D. Ronnie Moussa, M.D., Heather Licke, M.D., Boutros El-Haddad<br />

INTRODUCTION: This report promotes awareness to an emerging cannabis-induced syndrome that is<br />

beguiling to primary care doctors and gastroenterologist specialists and a major expense on the<br />

healthcare system.<br />

CASE PRESENTATION: Four different young adults presented with recurrent admissions complaining <strong>of</strong><br />

intractable nausea, vomiting, and epigastric pain with an incidental finding <strong>of</strong> excessive showering. They<br />

were all chronic heavy marijuana smokers. After extensive negative work up and observation <strong>of</strong><br />

symptomatic cessation upon the discontinuation <strong>of</strong> marijuana, a diagnosis <strong>of</strong> exclusion was determined.<br />

DISCUSSION: Under the extrapolation <strong>of</strong> different animal model studies and basic science research, a<br />

hypothetical mechanism may explain why these patients present with these characteristic symptoms.<br />

The manifestation <strong>of</strong> chronic ?9-tetrahydrocannabinol (?9-THC) may not show until after a long time and<br />

is reproducible when exposure to ?9-THC supersaturates the cannabinoid receptor-1 (CB-1). Chronic ?9-<br />

THC exposure appears to desensitize the gabanergic effects <strong>of</strong> CB-1 which is known to cause intestinal<br />

hypomotility, analgesia, and hypothermia. Extensive gastrointestinal workup is usually non-yielding and<br />

may impose financial burden on the healthcare system.<br />

RETROPERITONEAL COMPARTMENT SYNDROME<br />

Samuel Kilaho Akidiva, MD<br />

INTRODUCTION: Acute necrotizing pancreatitis is a disease with high mortality even in the best<br />

practice settings. The patients who survive <strong>of</strong>ten have multiple different chronic complications some<br />

requiring lifelong modifications to the survivor’s lifestyle. Key amongst these is diabetes, chronic<br />

exocrine pancreatic insufficiency, and chronic renal failure. These complications may require<br />

replacement therapy with enzymes, hormones, and renal replacement therapy. We highlight a cause <strong>of</strong><br />

potentially reversible renal failure in the setting <strong>of</strong> necrotizing pancreatitis.<br />

CASE PRESENTATION: A 60-year-old Caucasian male presented having been treated previously at an<br />

outside hospital after diagnosis <strong>of</strong> necrotizing pancreatitis three months prior. At presentation, he<br />

complained <strong>of</strong> easy satiety and intractable nausea and vomiting. He was on scheduled dialysis 3<br />

days/week. Examination revealed jaundice, cachexia, abdominal distention, and edema. Laboratory<br />

showed bilirubin 6.2 (direct 4.2), prealbumin 11, alkaline phosphatase 1467, and glucose 214. Imaging<br />

revealed extensive pancreatitis with pancreatic psuedocysts, dilatation <strong>of</strong> the intrahepatic ducts,<br />

retroperitoneal inflammation, and normal kidney and ureters.<br />

Surgery was performed for drainage <strong>of</strong> the pseudocyst. On incision, the contents <strong>of</strong> the pseudocysts<br />

were found under intense pressure splashing across the operating room. Within minutes <strong>of</strong> drainage,<br />

the patient who had been oliguric over the last 3 months started to make normal urine volumes. The<br />

kidney function continued to improve and although the patient required dialysis on two occasions after<br />

surgery. The creatinine stabilized at 1.5 and he has not required dialysis since.<br />

DISCUSSION: Preventing any long term sequel <strong>of</strong> any disease process greatly improves patients’ quality<br />

<strong>of</strong> life and also reduces healthcare utilization with its attendant costs and risks. In a similar setting, it is<br />

important to consider this potentially reversible cause <strong>of</strong> renal failure and have timely intervention to<br />

prevent chronic renal failure requiring lifelong dialysis.<br />

Leukemoid Reaction And Autocrine Growth Of Bladder Cancer Induced By Paraneoplastic Production<br />

Of G-CSF<br />

Anup Kumar Kasi Loknath Kumar, MBBS, MPH Second Author: Jeffrey Holzbeierlein MD Third Author:<br />

Peter VanVeldhuizen MD<br />

INTRODUCTION:Granulocyte-colony stimulating factor (G-CSF) produced by nonhematopoietic<br />

malignant cells is able to induce a leukemoid reaction by excessive stimulation <strong>of</strong> leukocyte production.<br />

Expression <strong>of</strong> granulocyte-colony stimulating factor and its functional receptors have been confirmed in<br />

bladder cancer cells. In vitro studies have demonstrated that granulocyte-colony stimulating<br />

factor/receptor exhibits a high affinity binding and this biological axis increases proliferation <strong>of</strong> the<br />

carcinoma. The clinico-pathological aspects, biology, prognosis and management <strong>of</strong> granulocyte-colony<br />

stimulating factor secreting bladder cancers are poorly understood.<br />

CASE PRESENTATION: A 39 year old Caucasian female with an invasive high grade urothelial carcinoma<br />

presented with hematuria and low grade fevers. Labs revealed an elevated white blood cell count,<br />

absolute neutrophil count and an elevated 24 hour urine protein. Upon further evaluation she was<br />

found to have locally advanced high grade urothelial carcinoma without nodal or distant<br />

metastasis. Serum Granulocyte-colony stimulating factor level was 10 times the normal limit. This led to<br />

the diagnosis <strong>of</strong> a paraneoplastic leukemoid reaction. Her WBC count immediately normalized after<br />

cystectomy but increased in concordance with recurrence <strong>of</strong> her disease.<br />

DISCUSSION: This is one <strong>of</strong> the few cases reported that illustrates the existence <strong>of</strong> a distinct and highly<br />

aggressive subtype <strong>of</strong> bladder cancer which secretes granulocyte-colony stimulating factor. Patients<br />

presenting with a leukemoid reaction should be tested for granulocyte-colony stimulating<br />

factor/receptor biological axis. Moreover, granulocyte-colony stimulating factor could be a potential<br />

neoplastic marker as it can follow the clinical course <strong>of</strong> the underlying tumor and thus be useful for<br />

monitoring its evolution. Neo-adjuvant chemotherapy should be considered in these patients due to the<br />

aggressive nature <strong>of</strong> these tumors. With a better understanding <strong>of</strong> the biology, this autocrine growth<br />

signal could be a potential target for therapy in future.<br />

Neurosarcoidosis Presenting as Trigeminal Neuralgia<br />

Sapna A Shah-Haque, MD, MBA Second Author: Sherri Braksick, MD Third Author: Ronnie Moussa, MD<br />

Fourth Author: Boutros El-Haddad, MD<br />

INTRODUCTION:Sarcoidosis is a granulomatous disease that primarily affects the pulmonary system,<br />

but may also involve other organ systems. It is reported across all races, with a higher incidence among<br />

African <strong>American</strong>s. Neurological involvement in sarcoidosis is rare, with cranial nerve seven being the<br />

most reported neurological finding. Trigeminal neuralgia, as presented in this case, is uncommon.<br />

CASE PRESENTATION: A 38-year-old African <strong>American</strong> female, with a history <strong>of</strong> refractory trigeminal<br />

neuralgia and pathologically confirmed cutaneous sarcoidosis, presented to the hospital for fifth cranial<br />

nerve decompression <strong>of</strong> a suspected impinging vascular loop. She had failed medical therapy and<br />

gamma knife treatment. Prior to surgery, magnetic resonance imaging revealed an enhancing mass <strong>of</strong><br />

1.5 cm x 0.6 cm x 1.1 cm in the left Meckel’s cave, which, when compared with prior imaging, was not<br />

present. A partial craniotomy was performed, the mass was excised, and symptoms resolved. Frozen<br />

pathological sections showed granulomatous inflammation consistent with sarcoidosis. Stains for acid<br />

fast bacilli and fungi were negative, as were Quantiferon Gold and HIV serum studies. High resolution<br />

computed tomography scan <strong>of</strong> the chest showed patchy infiltrates in the lungs suspicious for chronic<br />

interstitial lung disease. She was dismissed home on a tapering dose <strong>of</strong> dexamethasone and follow-up<br />

with a rheumatologist.<br />

DISCUSSION: When a patient with a history <strong>of</strong> sarcoidosis presents with neurological symptoms,<br />

neurosarcoidosis should be considered. Most cases are diagnosed at autopsy, indicating the prevalence<br />

<strong>of</strong> this disease is higher than reported. Recognizing and correctly diagnosing neurosarcoidosis, though<br />

rare, leads to treatment and decreased morbidity in patients.<br />

Acute Tapeworm Infection With Pulmonary Hypertension And Reactive Arthritis: First Reported Use Of<br />

Polarized Light In Diagnosing A Pulmonary Parasite<br />

Neil Crittenden, MD, Hanan Farghaly, MD, Forest W. Arnold, DO, MSc, Charlene K. Mitchell, MD, MSPH<br />

INTRODUCTION: We report a challenging case <strong>of</strong> an acute tapeworm lung infection secondary to<br />

hematogenous inoculation from a dog bite. The patient presented with dyspnea and knee pain and<br />

diagnosis was aided by the first reported use <strong>of</strong> polarized light on both bronchoalveolar lavage (BAL) and<br />

lung tissue specimens.<br />

CASE PRESENTATION: A 29-year-old male presented with knee pain. He reported three<br />

hospitalizations the prior month for dyspnea. He was diagnosed with eosinophilic pneumonia based on<br />

an initial rapid resolution <strong>of</strong> his dyspnea and eosinophilia with steroids. Following the third<br />

hospitalization, he required home oxygen and prednisone 60 mg daily. On admission to our hospital, he<br />

complained <strong>of</strong> sudden knee pain and a 24-pound weight loss over 4 weeks. On exam, there was joint<br />

tenderness <strong>of</strong> both knees without effusions, warmth, or erythema. Lung exam was clear.<br />

Laboratory results showed a WBC count <strong>of</strong> 38,000 with 10% eosinophils; hemoglobin 12.7, an elevated<br />

C-reactive protein <strong>of</strong> 5 (0-0.49 mg/dL) and IgE <strong>of</strong> 465 (=114 kU/L). The patient’s ANA, Rheumatoid<br />

Factor, and HIV status were all negative. Plain x-rays <strong>of</strong> the chest and knees were normal. CT scan <strong>of</strong><br />

the chest showed a widened pulmonary artery trunk <strong>of</strong> 4 cm. An echocardiogram revealed a pulmonary<br />

systolic artery pressure <strong>of</strong> 68 mmHg. The BAL was reported to have fungal spores and hyphae<br />

suggestive <strong>of</strong> Candida. Thorascopic lung wedge biopsies revealed a diffuse perivascular interstitial<br />

foreign body-type granulomatous reaction in all three lobes. Polarizable foreign material was found<br />

diffusely within the granulomas and pulmonary arterioles, mimicking intravenous drug use. His stool<br />

was positive for a parasitic ovum. He denied intravenous drug use. He recalled his dog had a diarrheal<br />

illness during which she bit his finger, crushing the nail bed, prior to his illness.<br />

The lung biopsies and fluid from his earlier BAL were reexamined. Using polarized light revealed<br />

parasitic proglottids, a scolex and numerous primitive parasitic eggs originally identified as fungal<br />

contaminants.<br />

The patient was given a single dose <strong>of</strong> praziquantel 600 mg, which reversed his cor pulmonale symptoms<br />

within days. His knee pain, consistent with reactive arthritis, also resolved. One month later, his<br />

breathing had returned to baseline. Follow-up chest CT scan showed reduction <strong>of</strong> his pulmonary artery<br />

trunk from 4 cm to 2.8 cm.<br />

DISCUSSION: Acute hematogenous tapeworm inoculation with diffuse pulmonary perivascular<br />

interstitial foreign body-type granulomatous reaction with pulmonary artery hypertension is an atypical<br />

presentation. Our finding that use <strong>of</strong> polarized light can aid in identifying parasitic parts in lung<br />

specimens has not previously been reported.<br />

Tricuspid Valve Papillary Fibroelastoma Paradoxically Presenting with Transient Ischemic Attack: The<br />

Diagnostic Intricacy.<br />

Ziad A Taimeh, MD, John Loughran, MD, Marcus Stoddard, MD, Sumanth D. Prabhu, MD.<br />

INTRODUCTION:Transient ischemic attack (TIA) is generally considered to be vascular in origin; caused<br />

by thromboembolic disease <strong>of</strong> the carotid arteries or heart atria. Rarely, a primary cardiac tumor <strong>of</strong> the<br />

left side <strong>of</strong> the heart may be the cause <strong>of</strong> cerebrovascular ischemia, such as TIA or stroke. Tumors <strong>of</strong> the<br />

right side <strong>of</strong> the heart are usually asymptomatic. We present in this abstract a challenging case <strong>of</strong><br />

tricuspid valve fibroelastoma presenting with TIA and angina.<br />

CASE PRESENTATION: A 60-year-old white male, with past medical history significant for diabetes<br />

mellitus type 2, presented to our facility with multiple neurological complaints consistent with TIA and<br />

dull substernal chest pain consistent with cardiac angina. He did not report any shortness <strong>of</strong> breath,<br />

palpitations or loss <strong>of</strong> consciousness. He also did not have any dizziness, visual loss, or permanent focal<br />

neurological deficits. His physical examination was unremarkable, as was his laboratory<br />

workup. Cardiac enzymes were negative, and his electrocardiogram demonstrated sinus rhythm. The<br />

patient was admitted for TIA and cardiac ischemia workup. Heart catheterization was negative for any<br />

coronary artery disease, and carotid duplex imaging only showed mild non-obstructive disease <strong>of</strong> the<br />

arteries. Computed tomography (CT) <strong>of</strong> the head was negative. On the other hand, CT <strong>of</strong> the chest<br />

showed a 4.3 centimeter-in-diameter ascending aortic aneurysm, which had been stable for the past<br />

few years. The transthoracic, and thereafter the transesophageal, echocardiograms showed a 1.65 x 1.2<br />

x 0.9 centimeter mobile mass, attached to the anterior leaflet <strong>of</strong> the tricuspid valve. A patent foramen<br />

ovale (PFO) was also evident. Blood cultures were negative and the patient showed no signs <strong>of</strong><br />

infection. He was subsequently taken to the operating room for an elective removal <strong>of</strong> the tumor, with<br />

closure <strong>of</strong> the PFO. During the operation, a 1.7 cm yellow mass was excised, and the foramen ovale was<br />

subsequently closed. No other masses were identified, and the tricuspid valve was patent postoperatively.<br />

On further gross examination, the mass measured 1.7 x 1.1 x 0.6 cm, and was s<strong>of</strong>t and pale<br />

yellow, with gelatinous consistency. Microscopic sections showed multiple avascular branching papillae,<br />

covered with benign endothelium. No evidence <strong>of</strong> myxoma or malignancy was identified. Postoperatively,<br />

the patient did well with no recurrence <strong>of</strong> any chest pain or neurological deficits.<br />

DISCUSSION: Papillary fibroelastoma <strong>of</strong> the right side <strong>of</strong> the heart is an extremely rare primary cardiac<br />

tumor. Given the facts that this small tumor is frail and thrombotic, with catastrophic end results if left<br />

untreated, imaging modalities need to be optimized, and more awareness needs to be implemented for<br />

earlier diagnosis.<br />

Double Karma: Anti-GBM and ANCA (+) RPGN<br />

Dr. Shilpa Gadde, Dr. Hitarth Dave, Dr. Shaminder Gupta, Dr. James Crowe, & Dr. Robert Perrett<br />

INTRODUCTION: Type IV rapidly progressive glomerulonephritis is a rare form <strong>of</strong> glomerular insult and<br />

injury. Its prevalence is 0.47 cases per million per year with a mean age <strong>of</strong> onset around 59. Mortality<br />

and morbidity remains significant and requires close monitoring <strong>of</strong> the patient even during remission<br />

stages. Renal manifestations <strong>of</strong> the underlying disease process was not evident after a renal transplant.<br />

CASE PRESENTATION: 62 yr old Caucasian male with past medical history <strong>of</strong> hypertension,<br />

cerebrovascular accident, C-ANCA (+) focal crescentic glomerulonephritis (diagnosed by a renal biopsy),<br />

Anti-GBM antibodies, and hyperlipidemia presented with primary complaint <strong>of</strong> flank pain, greatest on<br />

left flank, for a period <strong>of</strong> two days. Concomitant complaints were dysuria, hematuria, and dribbling. He<br />

was nauseous, but denied chest pain, shortness <strong>of</strong> breath, hemoptysis, arthalgias or rashes. Patient was<br />

compliant with his medications <strong>of</strong> Mycophenolate and Prednisone for his glomerulonephritis. On<br />

presentation, his vitals were stable. Pertinent physical exam findings were only that <strong>of</strong> left flank<br />

tenderness and bruising on bilateral ankles. Labs were abnormal for white count <strong>of</strong> 40.8, potassium <strong>of</strong><br />

5.5, BUN <strong>of</strong> 58, creatinine <strong>of</strong> 3.04 (elevated from his baseline), and GFR <strong>of</strong> 21 (lower from baseline).<br />

Urinalysis revealed protein <strong>of</strong> 150, blood <strong>of</strong> 250, negative nitrites, leukocytes <strong>of</strong> 25, urine RBC>100, WBC<br />

26-50, many bacteria. CT abdomen/pelvis only revealed perinephric fat stranding. Despite adequate<br />

fluid resuscitation and renally dosed antibiotics, for presumed Pyelonephritis/UTI, BUN and creatinine<br />

rose. A repeat renal biopsy showed necrotizing and crescentic glomerulonephritis and global<br />

glomerulosclerosis, consistent with rapidly progressive glomerulonephritis. Immun<strong>of</strong>luorescence<br />

staining revealed linear band-like deposition <strong>of</strong> IgG on the glomerular basement membranes, proving<br />

Anti-GBM disease. In addition, concomitant high titer ANCA serology was evident in lab work. Thus the<br />

two impending diagnoses <strong>of</strong> anti-GBM disease, likely Goodpasture’s, and ANCA (+), likely Wegener’s,<br />

were entertained. As such, patient was appropriately started on plasmapheresis and Cyclophosphamide.<br />

Simultaneously, pulse dose corticosteroids were started and continued. Despite treatment initiation <strong>of</strong><br />

above, patients’ creatinine and BUN continued to trend up and he subsequently required hemodialysis<br />

prior to discharge.<br />

DISCUSSION: Rapidly progressive glomerulonephritis, RPGN, is a diagnosis made when renal function<br />

declines by more than 50% in under 3 months. Histopathological findings include crescent formation in<br />

glomeruli. RPGN is divided into four subtypes based on glomerular injury. My patient had Type IV RPGN<br />

which is a combination <strong>of</strong> Type I (Anti-GBM disease) and Type III (Pauci-immune, ANCA mediated).<br />

Effective treatment is provided with corticosteroids, immunosuppressants, and plasmapheresis.<br />

A twenty-five year old male with recurrent priapism<br />

Justin D Fowlkes, MD and Jessica F Duncan, MD<br />

INTRODUCTION: CASE PRESENTATION: A 25 year-old male was referred to our hospital for<br />

evaluation <strong>of</strong> priapism, enlarged spleen, and elevated white blood cell (WBC) count. Within the<br />

preceding 3 months, the patient had experienced two episodes <strong>of</strong> priapism and mild fatigue. On physical<br />

exam severe splenomegaly was noted with the spleen crossing the midline and extending beyond the<br />

pelvic rim. Complete blood count revealed a WBC count <strong>of</strong> 415,500 c/mm3, hemoglobin <strong>of</strong> 10.5 g/dL,<br />

and platelet count <strong>of</strong> 535,000 c/mm3. The manual differential count included 2% promyelocytes, 27%<br />

myelocytes, 15% metamyelocytes, 2% blasts, 10% basophils, and 5% eosinophils. Other pertinent<br />

laboratory data included a creatinine <strong>of</strong> 1.45 mg/dL, uric acid level <strong>of</strong> 11.6 mg/dL, and lactate<br />

dehydrogenase level <strong>of</strong> 577 u/L.<br />

The patient was placed on intravenous fluids, allopurinol, hydroxyurea, and broad spectrum antibiotics.<br />

After bone marrow biopsy, the patient underwent one session <strong>of</strong> leukapheresis. Bone marrow findings<br />

were consistent with a diagnosis <strong>of</strong> chronic myelogenous leukemia (CML) in the chronic phase.<br />

Fluorescence in situ hybridization revealed the BCR/ABL1 translocation product, confirming the<br />

diagnosis <strong>of</strong> CML.<br />

DISCUSSION: The incidence <strong>of</strong> CML is 1-2 cases per 100,000 persons, with priapism occurring as the<br />

presenting complaint in only 1-2% <strong>of</strong> adult males diagnosed. High WBC counts, usually in excess <strong>of</strong><br />

300,000 c/mm3, can result in a hyperviscosity state that impedes blood flow. Initial treatment focuses<br />

on lowering the WBC count with leukapheresis and chemotherapy. In patients newly diagnosed with<br />

CML, current guidelines recommend that first line chemotherapy consist <strong>of</strong> one <strong>of</strong> the tyrosine kinase<br />

inhibitors (TKIs) imatinib, nilotinib, or dasatinib. The landmark trial by S O’Brien and others in 2003 first<br />

demonstrated complete cytogenetic response and major molecular response to the TKI imatinibmesylate<br />

that were superior to standard <strong>of</strong> care at that time in chronic phase CML. Eight year follow-up<br />

data reported in 2009 showed the durability <strong>of</strong> these responses with a tolerable side effect pr<strong>of</strong>ile and<br />

an estimated overall survival <strong>of</strong> 85%. In 2010, Saglio and colleagues compared nilotinib, a second<br />

generation TKI, to imatinib. These newer TKIs may provide more rapid cytogenetic and molecular<br />

responses.<br />

We ultimately chose treatment with imatinib-mesylate based on its favorable long term follow-up data.<br />

We also continued hydroxyurea for 6 weeks to control the WBC count. The main nonhematologic side<br />

effects reported for first and second generation TKIs are superficial edema, nausea and diarrhea. At 8<br />

week follow-up, the patient no longer experienced priapism, had no imatinib related side effects, and<br />

had a major hematologic response.<br />

Acute Renal Failure in a Woman with Human Immunodeficiency Virus and Medication-induced Fanconi<br />

Sydrome<br />

Christian Mabry, MD and D. Luke Glancy, MD Medical Center <strong>of</strong> Louisiana in New Orleans, Louisiana<br />

INTRODUCTION:Vertical transmission <strong>of</strong> HIV continues to be a serious health problem in developing<br />

countries with over 95% <strong>of</strong> congenital HIV occurring in these areas. Most <strong>of</strong> these infected neonates<br />

acquire the virus either during or near the time <strong>of</strong> delivery. The widespread use <strong>of</strong> highly active<br />

antiretroviral therapy (HAART) has decreased this transmission rate from 25% (no treatment) to 2%. This<br />

rate can be further decreased to less than 1% if prophylactic Cesarean section is performed in mothers<br />

with viral loads greater than 1000. The potential complications <strong>of</strong> HAART should never outweigh the<br />

benefits <strong>of</strong> starting this treatment as soon as the infection is found. Data from 2004 showed a 95%<br />

decrease in perinatally acquired cases <strong>of</strong> Acquired Immune Deficiency Syndrome (AIDS) when the<br />

appropriate preventive measures were taken.<br />

CASE PRESENTATION: A 19-year-old female with congenital human immunodeficiency virus (HIV)<br />

presented to the hospital with nausea, vomiting, diarrhea, and generalized fatigue for one week. Her<br />

CD4 count at admission was 27. She had been taking a combination <strong>of</strong> Ten<strong>of</strong>ovir, Lamivudine, and<br />

Lopinavir/Ritonavir (Kaletra) over the previous two months for her viral infection. The patient was found<br />

to have a creatinine <strong>of</strong> 1.6 (baseline 0.8 two months before), bicarbonate <strong>of</strong> 8, phosphorus <strong>of</strong> 3.4,<br />

potassium <strong>of</strong> 5.5, and a chloride <strong>of</strong> 144. It was suspected that the patient had developed Fanconi<br />

Syndrome from her Ten<strong>of</strong>ovir treatment and required large amounts <strong>of</strong> fluid and electrolyte<br />

replacement to normalize these values. Her acute renal failure resolved once Ten<strong>of</strong>ovir was<br />

discontinued and her clinical improvement mirrored the improvement in her electrolytes.<br />

DISCUSSION: Ten<strong>of</strong>ovir is a Nucleotide Reverse Transciptase Inhibitor which prevents replication <strong>of</strong> the<br />

virus by competing for incorporation into its DNA. Fanconi Syndrome is a known complication <strong>of</strong> this<br />

drug that occurs in about 1.6% <strong>of</strong> patients who use it. The nephrotoxicity <strong>of</strong> Ten<strong>of</strong>ovir is due to<br />

mitochondrial dysfunction. This causes a significant decrease in the energy used by the Na+-K+ pump in<br />

the proximal tubules. This disruption allows for electrolytes and small molecules that would normally be<br />

reabsorbed to be lost in the urine. The result is a proximal renal tubular acidosis with<br />

hypophosphatemia, glucosuria, and aminoaciduria (Fanconi Syndrome). Fanconi Syndrome is a<br />

complication <strong>of</strong> Ten<strong>of</strong>ovir and should be monitored for in every HIV patient on HAART. The benefits <strong>of</strong><br />

this medication can be enormous but this success can be quickly erased if the clinician is not constantly<br />

monitoring for signs <strong>of</strong> renal insufficiency.<br />

Nausea, Vomiting, and Diarrhea in a Patient with Hepatitis C and Acquired Immune Deficiency<br />

Syndrome<br />

Christian Mabry, MD, Charles V. Sanders, MD, and John J. Hutchings, MD Medical Center <strong>of</strong> Louisiana in<br />

New Orleans, Louisiana<br />

INTRODUCTION:Portal hypertensive gastropathy (PHG) is a somewhat common complication <strong>of</strong><br />

cirrhotic and non-cirrhotic portal hypertension. The mosaic-like pattern with intermittent red spots<br />

seen on endoscopy was originally thought to be inflammatory in origin. It was not until the 1980s that<br />

the disease was proven to stem from vascular ectasia and not erosive inflammation. This new<br />

understanding <strong>of</strong> its pathophysiology explains why anemia is a common and life-threatening presenting<br />

symptom. As the gastric mucosal blood flow responds to increasing pressures within the portal system,<br />

there is both congestion and hyperemia within the stomach. Gastroenterologists are able to see these<br />

changes on endoscopy and classify them as either mild or severe. Patients with known chronic hepatitis<br />

C, like our patient, have been shown to develop PHG at a rate <strong>of</strong> about 13% per year and to have<br />

progression <strong>of</strong> their gastropathy at a rate <strong>of</strong> about 6% per year.<br />

CASE PRESENTATION: A 42-year-old male with a past medical history <strong>of</strong> HIV/AIDS (his most recent CD4<br />

count, 4 months before admission, was 19) and hepatitis C presented to the Emergency Department<br />

complaining <strong>of</strong> 1 week <strong>of</strong> persistent nausea, vomiting, and diarrhea. He stated that he had been<br />

vomiting approximately 2 to 3 times per day but denied any blood in the vomitus. His admit labs were<br />

as follows: hemoglobin <strong>of</strong> 11.8, hematocrit <strong>of</strong> 35, total white blood cell count <strong>of</strong> 3.9, total protein <strong>of</strong> 6.0,<br />

albumin <strong>of</strong> 1.6, total bilirubin <strong>of</strong> 2.3, aspartate aminotransferase (AST) <strong>of</strong> 141, alkaline phosphatase<br />

(ALP) <strong>of</strong> 146, and alanine aminotransferase (ALT) <strong>of</strong> 31. A presumptive diagnosis <strong>of</strong> gastritis was made<br />

based on clinical presentation and broad-spectrum antibiotics were started. Computed tomography<br />

(CT) images <strong>of</strong> the abdomen and pelvis with contrast were obtained and showed diffuse, severe gastricwall<br />

thickening, consistent with edema. An esophagogastroduodenoscopy (EGD) was then performed<br />

and a diagnosis <strong>of</strong> portal hypertensive gastropathy was made.<br />

DISCUSSION: Imaging is not the preferred choice for diagnosing PHG when compared to direct<br />

endoscopic visualization. A study designed to verify this concluded that computed tomography can<br />

detect portal hypertensive gastropathy with a sensitivity <strong>of</strong> 75% and a specificity <strong>of</strong> 89%. In that same<br />

study, CT was also specific enough to exclude the diagnosis <strong>of</strong> PHG in all 92 control patients who were<br />

free <strong>of</strong> the disease. In light <strong>of</strong> these study results and the progression to diagnosis in our patient, we<br />

conclude that CT can be an effective means <strong>of</strong> aiding the diagnosis in the appropriate clinical setting.<br />

Diabetic Ketoacidosis induced Hypertriglyceridemic Acute Pancreatitis treated with Plasmapheresis –<br />

“Recipe for Biochemical Disaster Management”<br />

Abhishek Seth, MD Saurabh Rajpal, MD L Keith Scott, MD<br />

INTRODUCTION: Hypertriglyceridemia is the third most common cause <strong>of</strong> acute pancreatitis<br />

constituting 1-38% <strong>of</strong> cases <strong>of</strong> pancreatitis presenting to the hospital. Diabetic ketoacidosis (DKA)<br />

induced hypertriglyceridemia causing pancreatitis is an interesting phenomenon and has rarely been<br />

reported in literature.<br />

CASE PRESENTATION: 40-year old African <strong>American</strong> male with a past medical history <strong>of</strong> diabetes<br />

mellitus, hypertension, dyslipidemia, and recurrent pancreatitis s/p distal pancreatectomy presented<br />

with worsening abdominal pain and vomiting. The patient was found to be in DKA and was admitted to<br />

the medicine intensive care unit. On blood draw he was found to have milky plasma. He had a<br />

triglyceride level <strong>of</strong> 4854 mg/dl and serum lipase <strong>of</strong> 8223 U/L. CT scan revealed severe acute<br />

inflammatory change and edema <strong>of</strong> the residual pancreas. The patient received one session <strong>of</strong><br />

plasmapheresis for 4 hours after which the triglyceride level decreased to 629 U/L. Patient’s symptoms<br />

resolved after plasmapheresis and treatment <strong>of</strong> DKA. Subsequent stay in the hospital was uneventful<br />

and the patient was discharged on gemfibrozil for hypertriglyceridemia. The patient is being investigated<br />

for congenital hyperlipidemias, the results <strong>of</strong> which are still pending.<br />

DISCUSSION: Insulin deficiency leading to lipolysis coupled with inhibition <strong>of</strong> lipoprotein lipase in<br />

peripheral tissues results in hypertriglyceridemia in DKA. The mechanism by which hyperlipidemia leads<br />

to pancreatitis is less well established but a toxic role for accumulated free fatty acids in the pancreatic<br />

tissue has been suggested. Small studies have shown that DKA is associated with coexisting pancreatitis<br />

in about 10-15% <strong>of</strong> the cases <strong>of</strong> which hypertriglycerdemia is an identifiable factor. Plasmapheresis is<br />

well known treatment modality for hypertriglyceridemia induced pancreatitis and had excellent results<br />

in our patient.<br />

A Numb Chin and A Big Prostate: An Unusual Presentation <strong>of</strong> Lymphoma<br />

Karen Bascom, MD, Resident, Maine Medical Center, Portland, ME.<br />

INTRODUCTION:Lymphoma is a common malignancy with many subtypes and varied presentations.<br />

This case highlights the unusual ways in which lymphoma can present and the importance <strong>of</strong> having a<br />

high index <strong>of</strong> suspicion for malignancy in the out patient setting.<br />

CASE PRESENTATION: A 39 year old Caucasian male presented to the Emergency Department with a<br />

numb chin and back spasms. The patient presented initially to his Primary Care Provider (PCP)<br />

complaining <strong>of</strong> hesitancy and nocturia. An enlarged prostate was found on exam and the patient was<br />

started on tamsulosin without improvement in his symptoms. He subsequently presented complaining<br />

<strong>of</strong> left sided chin numbness. This was evaluated by a dentist, dental surgeon and neurologist and no<br />

apparent cause was found. On the morning <strong>of</strong> presentation the patient developed bilateral chin<br />

numbness and left tongue flaccidity. In addition he was experiencing diffuse muscle spasms which<br />

prompted him to present to the Emergency Department for evaluation. Review <strong>of</strong> symptoms was<br />

pertinent for significant weight loss and night sweats. On physical exam the patient was mildly<br />

hypertensive. Neurological exam revealed numbness <strong>of</strong> the chin, deviation <strong>of</strong> the tongue to the left on<br />

protrusion, and flaccidity and loss <strong>of</strong> fissures <strong>of</strong> the left side <strong>of</strong> the tongue. Prostate exam demonstrated<br />

a symmetrically enlarged, boggy prostate which was non tender to palpation. Complete blood count and<br />

complete metabolic panel revealed a mild leukocytosis, anemia with a normal MCV and a mild<br />

transaminitis. MRI <strong>of</strong> the mandible showed a small signal abnormality with the left hemimandible. CT <strong>of</strong><br />

the abdomen demonstrated bilateral adrenal masses, multiple liver lesions and retroperitoneal lymph<br />

nodes. Biopsy <strong>of</strong> the prostate and bone marrow returned with B cell lymphoma, with features<br />

intermediate between large B cell lymphoma and Burkitt's lymphoma. The patient was started on R-<br />

CHOP chemotherapy with intrathecal methotrexate prophylaxis. Unfortunately after five cycles <strong>of</strong><br />

chemotherapy the patient represented with altered mental status and was diagnosed with<br />

lymphomatous carcinomatosis. He died <strong>of</strong> complications <strong>of</strong> lymphoma less than six months after his<br />

diagnosis.<br />

DISCUSSION: This case illustrates an uncommon presentation <strong>of</strong> a common illness. Although the<br />

symptom <strong>of</strong> a numb chin is an unusual complaint it is well documented as a manifestation <strong>of</strong> underlying<br />

malignancy and has been explained by varied mechanisms including paraneoplastic syndromes and local<br />

compression <strong>of</strong> nerves. Prostatic lymphoma is rare but should be considered in patients with obstructive<br />

uropathy or an abnormal rectal exam, especially in patients with a prior history <strong>of</strong> lymphoma.<br />

Hemophagocytic lymphohistiocytosis and Disseminated Tuberculosis: Making a dual diagnosis<br />

Tanyaporn Wansom, MD, Ge<strong>of</strong>f Connors, MD, Satish Shanbhag, MBBS, MPH<br />

INTRODUCTION: Hemophagocytic lymphohistiocytosis (HLH) is a rare disorder <strong>of</strong> immunological<br />

activation resulting in multi-organ accumulation <strong>of</strong> histiocytes and lymphocytes which phagocytose<br />

other cell lines. Although the familial form is commonly seen in infancy, a secondary form can be seen in<br />

adults typically triggered by infection, malignancy, immunodeficiency or rheumatologic disorders. Rapid<br />

diagnosis is crucial, as HLH is usually fatal if untreated.<br />

CASE PRESENTATION: A 69 year old woman with hypertension and hypothyroidism was admitted for a<br />

six-month history <strong>of</strong> progressive bilateral lower extremity weakness that had rendered her unable to<br />

walk. She had immigrated to the US from the Philippines over forty years ago and was a retired<br />

schoolteacher. Her laboratory values on admission were notable for hemoglobin <strong>of</strong> 7.9%, sodium <strong>of</strong> 129,<br />

corrected calcium <strong>of</strong> 12.4, and creatinine <strong>of</strong> 2.5. During the course <strong>of</strong> her hospitalization, she developed<br />

high fevers, pancytopenia, disseminated intravascular coagulation, and gastrointestinal bleeding,<br />

ultimately culminating respiratory failure requiring intubation. Pleural fluid analysis from bilateral<br />

pleural effusions revealed an exudate; cytology showed reactive histiocytes and lymphocytes without<br />

atypia. Despite treatment with broad-spectrum antibiotics, the patient continued to be<br />

febrile. Rheumatologic workup, hepatitis serologies, HIV, RPR, were negative. Blood, sputum, and urine<br />

cultures were also negative; AFB smears <strong>of</strong> sputum and CSF were negative. PET scan showed FDG-avid<br />

retroperitoneal, mediastinal, left supraclavicular, and external iliac adenopathy. Lymph node biopsy was<br />

delayed secondary to coagulopathy. Bone marrow biopsy showed granulomatous inflammation,<br />

markedly increased histiocytes throughout the marrow space and several foci <strong>of</strong> hemophagocytosis.<br />

With improvement <strong>of</strong> her coagulopathy, lymph node biopsy was performed, revealing widespread<br />

necrosis superimposed on granulomatous inflammation. AFB smears <strong>of</strong> lymph node tissue were<br />

positive; the patient was empirically started on four-drug therapy for Mycobacterium tuberculosis<br />

(MTB). Lymph node and sputum cultures eventually grew MTB. A diagnosis <strong>of</strong> HLH was made as the<br />

patient met diagnostic criteria including fever, pancytopenia, hypertriglyceridemia, hyperferritinemia,<br />

transaminitis, and hemophagocytosis on bone marrow biopsy. As HLH was secondary to MTB, no<br />

immunosuppressive therapy was instituted while awaiting response to anti-tubercular therapy. With<br />

treatment <strong>of</strong> her MTB, the patient clinically improved over weeks and was extubated successfully.<br />

DISCUSSION: This case underscores the importance <strong>of</strong> keeping reactivation <strong>of</strong> latent TB on the<br />

differential for patients presenting with the appropriate history, even if TB exposure occurred decades<br />

prior. Because mycobacteria <strong>of</strong>ten take weeks to culture, a high index <strong>of</strong> suspicion and AFB smears <strong>of</strong><br />

tissue can aid in early diagnosis. Secondary HLH is an uncommon, but <strong>of</strong>ten fatal sequelae <strong>of</strong> TB or<br />

other infections,and can mimic sepsis.<br />

In a 2006 review <strong>of</strong> HLH and TB, mortality was 50%, independent <strong>of</strong> therapy given. In the event <strong>of</strong> failure<br />

<strong>of</strong> anti-microbial therapy, a combination <strong>of</strong> immunosuppressants and cytotoxic chemotherapy should be<br />

instituted for patients with secondary HLH; a missed diagnosis is invariably fatal.<br />

Chapter Winning Abstract: A Case <strong>of</strong> Progressive Multifocal Leukoencephalopathy after Receiving a<br />

Monoclonal Antibody<br />

Kathy L Mcgill, DO and Barbara A Neilan, MD<br />

INTRODUCTION:Progressive multifocal leukoencephalopathy (PML) is an opportunistic infection<br />

usually related to HIV and AIDS. PML rarely occurs in other immunosuppressant settings. This is a report<br />

<strong>of</strong> a female whose cutaneous T-cell lymphoma was treated with a monoclonal antibody and who<br />

subsequently developed progressive multifocal leukoencephalopathy. We report this case to educate<br />

clinicians about this rare disease so it can be diagnosed in a timely manner<br />

CASE PRESENTATION: Ms. M, a 38 year old female, was diagnosed with cutaneous T-cell lymphoma in<br />

2008. Due to disease progression she was treated with various agents over these three years including<br />

methotrexate, Targretin, Folotyn, Ontak, and radiation therapy. Most recently she received 2 doses <strong>of</strong><br />

brentuximab with excellent cutaneous response.<br />

Several days after receiving her 2 nd dose <strong>of</strong> brentuximab she developed difficulty with reading numbers,<br />

specifically reading her credit card number over the phone. She also developed problems with word<br />

finding and ataxia.<br />

Neurological exam revealed a patient who was awake and alert but who had significant cognitive<br />

deficits. She followed most commands; however, she was slow in doing so. Her speech was<br />

understandable, but she answered questions incorrectly about 90% <strong>of</strong> the time. Her right pupil was<br />

slightly larger than her left pupil but both pupils were reactive to light. Cranial nerves II through XII were<br />

grossly intact. Her strength was 4/5 bilaterally<br />

A MRI showed multiple cortical and white matter lesions within the supratentorial and infratentorial<br />

parenchyma with mild associated edema and a mild degree <strong>of</strong> tonsillar herniation. The patient<br />

underwent a brain biopsy with pathology revealing JC virus.<br />

Further brentuximab dosing has been avoided. She was discharged home and is improving<br />

neurologically.<br />

DISCUSSION: By adulthood, 86% <strong>of</strong> individuals test positive for antibodies against the JC virus. In<br />

asymptomatic individuals the JC virus lies dormant in the kidneys and lymphoid tissue. However, when<br />

a person becomes immunosuppressed the JC virus becomes activated and disseminates to the brain.<br />

Once in the brain the virus infects oligodendrocytes causing cell lysis, demyelination, and PML. Mortality<br />

is high with a median survival time <strong>of</strong> 3 months in patients without HIV.<br />

Brentuximab, a monoclonal antibody against CD30, was recently approved by the FDA for treatment <strong>of</strong><br />

anaplastic large cell lymphoma. The temporal relationship between the administration <strong>of</strong> brentuximab<br />

and the patient’s onset <strong>of</strong> PML suggests a causal association between the two. The brentuximab<br />

possibly suppressed her immune system allowing activation <strong>of</strong> the JC virus and subsequent PML. One<br />

confirmed case <strong>of</strong> PML associated with brentuximab therapy was reported during clinical trials. Other<br />

monoclonal antibodies such as natalizumab, efalizumab, and rituximab have also been associated with<br />

PML.<br />

Successful Treatment Of Myeloma Cast Nephropathy With Plasma Exchange And Chemotherapy<br />

Shan Shan Chen, MBBS.Others: Tamil Kuppusamy, MD, Moon Shan Lui, MBBS<br />

INTRODUCTION: Myeloma cast nephropathy is the most common cause <strong>of</strong> severe renal failure in<br />

patients with multiple myeloma. Studies have revealed that early reduction <strong>of</strong> serum free light chains<br />

(FLCs) can facilitate renal recovery, which can lead to significant survival benefits. Principal treatment<br />

modalities to reduce FLCs include 1) diminished production rates by effective chemotherapy 2) direct<br />

removal <strong>of</strong> FLCs from serum by plasma exchange (PLEX) or high cut-<strong>of</strong>f hemodialysis. However, there are<br />

no clear treatment guidelines for cast nephropathy and literature discrepancies exist for the role <strong>of</strong><br />

PLEX.<br />

CASE PRESENTATION: We present the case <strong>of</strong> a 64-year-old female with hypertension and worsening<br />

renal failure. She denied using NSAIDs or diuretics. Laboratory results were notable for a urinalysis with<br />

2+ protein and 1+ blood as well as serum and urine immun<strong>of</strong>ixation electrophoresis studies positive for<br />

lambda light chains. A renal biopsy was consistent with lambda light chain cast nephropathy, diffuse<br />

acute tubular injury and acute interstitial inflammation. The bone marrow biopsy demonstrated a<br />

plasma cell neoplasm with 60% lambda light chain restricted plasma cells. A fluorescent in situ<br />

hybridization panel revealed positivity for monosomy 13 in 8.8% <strong>of</strong> the cells and 3 copies <strong>of</strong> 1q21,<br />

including CKS1B which are adverse prognostic indicators. The patient subsequently underwent<br />

treatment with five sessions <strong>of</strong> PLEX concurrently with dexamethasone. This was followed by a<br />

chemotherapy regimen <strong>of</strong> dexamethasone, bortezomib and cyclophosphamide. After one course <strong>of</strong><br />

PLEX, serum FLCs and 24-hour urine lambda light chain decreased by 80% in 24 hours and then by 99%<br />

45 days later. Renal function improved from a serum creatinine <strong>of</strong> 4.5 mg/dl at the time <strong>of</strong> diagnosis to<br />

2.9 mg/dl after 45 days.<br />

DISCUSSION: We present a case <strong>of</strong> lambda light chain cast nephropathy successfully treated with PLEX<br />

and high dose dexamethasone followed by bortezomib-based chemotherapy. Although a randomized<br />

control trial by Clark et al. suggested no substantial benefit <strong>of</strong> PLEX for acute kidney injury in patients<br />

with multiple myeloma, renal pathology was not verified by biopsy in their trial. In Pozzi et al. study, only<br />

66.67% <strong>of</strong> 24 patients had myeloma kidney when renal biopsy was performed, suggesting not all <strong>of</strong> the<br />

multiple myeloma patients presenting with acute kidney injury had myeloma cast nephropathy. Leung<br />

et al. demonstrated the relationship between renal recovery and free light chain reduction was present<br />

only in biopsy proven cases <strong>of</strong> myeloma cast nephropathy. Hutchison et al. study also recommended<br />

direct removal <strong>of</strong> FLCs from serum as an option for patients with biopsy-proven myeloma kidney. While<br />

our patient’s recovery may have been coincidental, further study with biopsy-proven cases is required to<br />

further delineate the role <strong>of</strong> PLEX in myeloma cast nephropathy.<br />

3 cases <strong>of</strong> negative pressure pulmonary edema: an acute, potentially lethal post-anesthesia<br />

complication<br />

Stefan David, MD Venkataraman Palabindala, MD, Smriti Manandhar, MD, Rajesh Tota-Maharaj, MD,<br />

San Thida, MD, Surendra Marur, MD, MPH, FACP, and Brian Bohner, MD<br />

INTRODUCTION: Negative pressure pulmonary edema (NPPE) represents a potentially fatal condition<br />

characterized by rapid intraalveolar fluid accumulation occurring in post-anesthesia setting. Prevalence<br />

is less than 0.1%, but it may be underreported.<br />

Two NPPE types are described. In type I NPPE, inspiration against an upper airway obstruction reduces<br />

the intrathoracic pressure and results in fluid extravasation. Type II NPPE occurs in patients with chronic<br />

obstruction resulting in PEEP. Once the obstruction is removed, a relative state <strong>of</strong> negative pressure<br />

results in intraalveolar flooding. If properly recognized and treated, NPPE has an excellent prognosis<br />

CASE PRESENTATION: We are hereby reporting 3 cases <strong>of</strong> young patients with acute pulmonary<br />

edema developed status post extubation:<br />

-21 years old (yo) African <strong>American</strong> man, with history <strong>of</strong> asthma, hads general anesthesia for dental<br />

abscess drainage and molar extraction became hypoxic after extubation (SaO2 78%). The patient<br />

received high flow oxygen via mask and was transferred to ED. Chest XRay (CXR) revealed diffuse<br />

bilateral infiltrates suspicious for pneumonitis or noncardiogenic pulmonary edema. CT angiogram (CTA)<br />

excluded pulmonary embolism (PE). Echocardiogram revealed normal left ventricular function and mild<br />

right ventricle (RV) dilation and hypokinesis The patient received Oxygen supplementation via Venturi<br />

mask and 40mg <strong>of</strong> Lasix iv, with subsequent gradual improvement and CXR normalization in three days<br />

after admission<br />

-30 yo previously healthy African <strong>American</strong> woman developed hypoxic respiratory failure with high A-a<br />

gradient after abdomino-plasty and liposuction. After extubation the patient had rales and her oxygen<br />

saturation dropped. After administering 20mg <strong>of</strong> lasix iv, the patient was transferred to ED. CXR<br />

revealed bilateral infiltrates. CTA showed no evidence <strong>of</strong> PE. Echocardiography revealed normal<br />

ventricular motion and filling. Patient was placed on BiPAP (15/5, with FiO2 50%) with gradual<br />

improvement occurring overnight ( SaO2 reached 100% on room air and pulmonary infiltrates clearing<br />

on CXR).<br />

-27 years old African <strong>American</strong> woman extubated after liposuction, became hypoxic (SaO2 40%) once<br />

extubated after liposuction. . The patient received 40mg Lasix iv and high flow oxygen prior to ED<br />

transfer. CXR showed extensive pulmonary infiltrates. Additional 60mg <strong>of</strong> lasix were administered<br />

(followed by 3.8L diuresis) and the patient was placed on BiPAP with subsequent gradual rapid recovery.<br />

The patient also had a history <strong>of</strong> snoring, suggestive <strong>of</strong> obstructive sleep apnea and subsequent<br />

pulmonary hypertension, known augment the risk <strong>of</strong> her NPPE<br />

DISCUSSION: Our cases emphasize that physicians should be aware <strong>of</strong> NPPE - an underreported postanesthesia<br />

event, occurring in young patients. Although rare, NPPE may be lethal, if not properly<br />

recognized and treated. Correct diagnosis may avoid further unnecessary tests.<br />

Acute psychosis as a manifestation <strong>of</strong> Lyme disease<br />

Ezza Aslam Khan,MD Other : Helen Gordon, MD<br />

INTRODUCTION: Borrelia Burgdorferi can involve the nervous system in 10-15% <strong>of</strong> cases <strong>of</strong> Lyme<br />

disease. Neurological, cognitive and psychiatric symptoms occur in the later stages <strong>of</strong> the disease. We<br />

present a case <strong>of</strong> neurological Lyme, presenting as an episode <strong>of</strong> acute psychosis.<br />

CASE PRESENTATION: Ms. W, a 28 year old female with no significant past history, had been having<br />

paraesthesias <strong>of</strong> various parts <strong>of</strong> her body for a few months, lasting a few minutes, recently diagnosed<br />

with depression with difficulty concentrating. During current episode, symptoms once again began with<br />

paraesthesias, followed by drooling from left side <strong>of</strong> her mouth and blurring <strong>of</strong> vision. She developed<br />

extreme agitation, became combative and had to be held down by 5 people. She was given olanzapine<br />

for sedation. Several hours later, patient had no recollection <strong>of</strong> this psychotic episode. She continued to<br />

be drowsy and lethargic. An electroencephalogram was consistent with diffuse encephalopathy.<br />

Previously, she was admitted with similar neurological complaints without psychosis, a CT scan,<br />

MRI/MRA was negative. Repeat imaging on this admission were also negative as was urine toxicology for<br />

illicit substances. Since patient was residing in a Lyme endemic area serologies were done which were<br />

positive, later confirmed by western blot. An LP was done in light <strong>of</strong> neurological complaints and was<br />

consistent with aseptic meningitis. Patient completed 3 weeks <strong>of</strong> IV ceftriaxone following which her<br />

symptoms significantly improved.<br />

DISCUSSION: Borrelia Burgdorferi is known to affect the nervous system. In the acute setting,<br />

symptoms <strong>of</strong> meningitis and cranial neuropathy are well documented. In the sub-acute and chronic<br />

settings, symptoms can be neurological, cognitive or psychiatric. If there is no clear cut history <strong>of</strong> a tick<br />

bite, rash, joint pain or a flu-like illness, diagnosis can <strong>of</strong>ten be missed.<br />

Conclusion: Neuroborreliosis has varied presentation. In endemic areas, prior to diagnosing a patient<br />

with a psychiatric condition it is important to rule out Lyme disease.<br />

INTRODUCTION: Ascites results in abdominal distension and weakening <strong>of</strong> the abdominal wall. 20% <strong>of</strong><br />

patients with both cirrhosis and ascites develop umbilical hernias. Flood’s Syndrome, represented by<br />

umbilical hernia rupture with subsequent loss <strong>of</strong> ascitic ascitic fluid is a rare, under-reported event<br />

associated with 30% mortality rate.<br />

CASE PRESENTATION: A 58-year-old woman with advanced cirrhosis (MELD score 19) and recurrent<br />

ascites refractory to paracentesis and diuretics, presented with drainage <strong>of</strong> large amounts <strong>of</strong> serous fluid<br />

from her umbilicus after scratching the area earlier. Ascitic fluid drainage could not be controlled, so she<br />

came to emergency department. Prior to being diagnosed with cirrhosis, the patient was in good health.<br />

Liver biopsy showed evidence <strong>of</strong> cirrhosis, but could not define any specific etiology. Hepatitis B and C<br />

serologies were negative. Non-alcoholic fatty liver disease was considered the most likely cause <strong>of</strong> the<br />

patient’s cirrhosis.Family and social history is non-contributory.<br />

Physical examination revealed scleral icterus, dry mucous membranes and distended abdomen with<br />

massive ascites. Laboratory studies on admission showed hematocrit <strong>of</strong> 31.6, platelet count <strong>of</strong> 85,000<br />

and white count <strong>of</strong> 4900. PT was 17.0 with an INR <strong>of</strong> 1.31.<br />

During hospitalization, the patient received IV fluid hydration. It was reported that 3 liters <strong>of</strong> ascitic fluid<br />

was drained spontaneously into the collection bag attached to the abdominal wall defect when she sat<br />

up. The patient was therefore transferred to a university medical center where she had an emergent<br />

surgical repair <strong>of</strong> the umbilical hernia rupture. Unfortunately, post-operative care was complicated and<br />

the patient died from septic shock.<br />

DISCUSSION: We describe the unfortunate case <strong>of</strong> a patient with Flood’s syndrome (i.e.: umbilical<br />

hernia rupture secondary to uncontrolled ascites that resulted in the thinning <strong>of</strong> the abdominal wall). In<br />

these cases surgical repair is complicated not only by the fragility <strong>of</strong> the abdominal wall, but also by the<br />

protein depletion due to ascitic fluid loss, superimposed on poor nutritional status secondary to<br />

cirrhosis.. In addition to protein loss and hypovolemia, infection is a frequent, life-threatening<br />

complication. Timely intervention to reduce portal hypertension (e.g. by TIPS), despite its complications,<br />

may prevent this late desperate development occurring in uncontrolled ascites.<br />

Stiff–Person Syndrome<br />

Hui Peng, MD Jennifer Dearborn, Xian Yan, Steve Ayres, Venkataraman Palabindala, Bharath<br />

Alamelumangapuram, William Hagopian, Arun Venkatesan<br />

INTRODUCTION: Stiff-person syndrome (SPS, previously stiff man syndrome) is an extremely rare<br />

(fewer than 1 per million) neurological disorder which involves severe stiffness and pr<strong>of</strong>ound muscle<br />

spasms and highly associated with diabetes mellitus. The pathogenesis <strong>of</strong> SPS is a highly specific<br />

antibody against the 65-kDa is<strong>of</strong>orm <strong>of</strong> glutamic acid decarboxylase (GADA), which is involved in<br />

gamma-aminobutyric acid transmission. This antibody is present in approximately 60 percent <strong>of</strong><br />

patients.<br />

CASE PRESENTATION: A 47 year old Caucasian woman with a 10 year history <strong>of</strong> muscle spasms,<br />

difficulty walking and performing daily activities. She started falling due to muscular rigidity initially, and<br />

has been walking on her tip toes secondary to contractures. Her significant muscle spasms with pain are<br />

in her legs and her back. A variety <strong>of</strong> diagnoses including stress disorder, dystonia, radiculopathy and<br />

myopathy were previously postulated. Recently she was diagnosed with diabetes without ketoacidosis<br />

and well controlled with metformin. She was admitted to the neurology service due to poor<br />

symptomatic control by benzodiazepines and balc<strong>of</strong>en and failure <strong>of</strong> intravenous immunoglobulin (IVIG)<br />

monthly for 1 year at home (3 consecutive days). Physical examination showed significant lordosis and<br />

contraction <strong>of</strong> the paraspinal muscles, spastic gait and increased muscle tone caused by contraction <strong>of</strong><br />

gastrocnemius and anterior tibialis muscles. Sensation was intact throughout. Electromyography<br />

demonstrated contraction <strong>of</strong> antagonistic muscles. Lumbar spine MRI indicated degenerative changes,<br />

with no evidence <strong>of</strong> myelopathy or radiculopathy. Repeatedly, Quest Diagnostics found GADA level to be<br />

over 30u/mL (maximum range) which was 20.7u/ml when she was diagnosed with SPS three years ago.<br />

Quantifying autoantibody levels using specific radioligand assays and HLA genotyping were measured.<br />

Her GADA index was strongly positive at 0.6 (99 th =0.05). HLA typing revealed DQB*0201/*0302<br />

heterozygosity (DR 3/4) which is the genotype at greatest risk for type 1 diabetes. She had one 5-day<br />

course <strong>of</strong> IVIG in hospital with temporarily improved symptoms, requiring management by a pain<br />

specialist later.<br />

DISCUSSION: SPS diagnosis is <strong>of</strong>ten made by exclusion and requires high index <strong>of</strong> suspicion and<br />

treatment needs multiple specialists to collaborate. In this patient, symptoms persisted for 7 years<br />

before she was first tested for GADA. Patients may benefit from sequential trials <strong>of</strong> other<br />

immunotherapies. Psychiatric consultation may be helpful in managing the stress. The clinical<br />

presentation and presence <strong>of</strong> both GADA and a very high risk HLA genotype favor the diagnosis <strong>of</strong> latent<br />

autoimmune diabetes in adults (LADA), a subclass <strong>of</strong> type 1 diabetes. If the latter is indeed present, we<br />

would expect serum C-peptides to decrease over time, along with an eventual requirement for insulin<br />

therapy.<br />

Malignant peritoneal mesothelioma 37 years after intra-peritoneal radiotherapy with P-32.<br />

Abdulghani Saadi, MD , Marwa Hegagi, MD , Haneen Aibak MD, Richard Williams, MD, FACP. Harbor<br />

Hospital, Baltimore MD<br />

INTRODUCTION: Malignant peritoneal mesothelioma (MPM) is an aggressive neoplasm that arises<br />

from the lining mesothelial cells <strong>of</strong> the peritoneum and rapidly spreads within the confines <strong>of</strong> the<br />

abdominal cavity. MPM is an understudied disease compared to the plural variant, although they share<br />

the same predominant risk factor, asbestos exposure. Our patient had a different story.<br />

Histopathology exhibited moderately differentiated malignant mesothelial cells with<br />

immunohistochemical staining positive for calretinin,cytokeratin 5,6,EMA,thrombomodulin and negative<br />

for Ber-EP4,ER,PR,all <strong>of</strong> which are compatible with moderate to poorly differentiated malignant<br />

epitheliod mesothelioma.<br />

CASE PRESENTATION: A 70 year old Caucasian woman presented with painless abdominal distention<br />

for 3 weeks, without weight loss. She had a past medical history <strong>of</strong> ovarian cancer 37 years previously,<br />

for which she underwent total abdominal hysterectomy and bilateral salpingo-oophorectomy followed<br />

by intraperitoneal radioactive phosphorus 32 radiotherapy in the early 1970s. She managed to lead an<br />

uneventful course for a solid 37 years after the treatment <strong>of</strong> her ovarian cancer. She was a nonsmoker,<br />

nondrinker. She reported no exposure to asbestos. She had worked as seamstress in a mattress factory<br />

for 20 years.<br />

On examination, she was an average build female, anicteric, with no stigmata <strong>of</strong> chronic liver disease,<br />

abdominal exam reveled ascites which was confirmed by ultrasound.<br />

She was mildly anemic with hemoglobin <strong>of</strong> 9.8 and hematocrit <strong>of</strong> 28.7. She had a normal liver pr<strong>of</strong>ile<br />

and negative viral hepatitis screen. CA 125 was elevated at 299. Paracentesis revealed exudative ascites<br />

with SAAG less than 1.1 and cytology showed atypical mesothelial cells.<br />

Exploratory laporatomy reveled ascites with peritoneal and liver seeding.<br />

P-32 is utilized in the treatment <strong>of</strong> peritoneal carcinomatosis. Patients who survive long term following<br />

such treatment are at risk <strong>of</strong> MPM.<br />

DISCUSSION: MPM is a very rare neoplasm. Asbestos exposure constitutes the major risk factor, just as<br />

for the more common pleural MM. Other risk factors include papovirus, thorotrast exposure, radiation,<br />

and chronic peritonitis. Our patient, however, had no history <strong>of</strong> asbestos exposure, and there was no<br />

histopathologic evidence <strong>of</strong> ferruginous bodies. The long latency period between her exposure to a<br />

potential carcinogen and the development <strong>of</strong> MM is typical and has been described in the literature on<br />

several occasions but mostly relating to exposure to radiotherapy for lymphomas and characteristically<br />

it has a very long latency <strong>of</strong> 2 to 3 decades.<br />

INTRODUCTION: Pseudohypoparathyroidism (PHP) refers to a group <strong>of</strong> inherited disorders with various<br />

clinical findings typical <strong>of</strong> hypoparathyroidism, <strong>of</strong>ten associated with skeletal and developmental<br />

abnormalities. Unlike true hypoparathyroidism whose hypocalcemia is due to parathyroid hormone<br />

(PTH) deficiency, in pseudohypoparathyroidism, hypocalcemia is associated to elevated parathyroid<br />

hormone levels but a deficient target organ response to the PTH. We report the case <strong>of</strong> a patient<br />

presenting with asymptomatic hypocalcemia, later found to have pseudohypoparathyroidism.<br />

CASE PRESENTATION: A 22-year-old Caucasian male presented to the Endocrine clinic upon referral <strong>of</strong><br />

his primary care provider for asymptomatic hypocalcemia. He reported fatigue and cold intolerance, but<br />

denied any changes in appetite or body weight. He had congenital hypothyroidism for which he was<br />

taking 137 mcg <strong>of</strong> levothyroxine daily but no other medical problems. He denied tobacco, alcohol, or<br />

illicit drug use. Physical examination showed a short-stature <strong>of</strong> 5-foot tall overweight male with a round<br />

facies. His fourth and fifth metacarpal bones (knuckles) were shortened bilaterally, demonstrating<br />

typical “Knuckle, Knuckle, Dimple, Dimple” appearance. There was no palpable thyroid gland. Laboratory<br />

investigations showed normal CBC and liver panel, calcium 8.1 mg/dL, phosphate 5 mg/dL, and intact<br />

PTH 496 pg/mL. 25-hydroxy Vitamin D level was within normal range. He was treated with oral vitamin D<br />

and calcium. After 2-3 months <strong>of</strong> therapy, serum calcium, phosphate and PTH levels normalized.<br />

DISCUSSION: Pseudohypoparathyroidism (PHP) can present in several ways, including asymptomatic<br />

hypocalcemia, neonatal hypothyroidism, hypogonadism. There are various forms <strong>of</strong> PHP, namely type I<br />

(i.e., Ia, Ib and Ic) and type II. PHP-I is the most common. PHP-I is transmitted in autosomal dominant<br />

fashion and is due to mutations in the GNAS1 gene on chromosome 20q13. GNAS1 gene codes for the<br />

stimulatory alpha-subunit <strong>of</strong> the trimeric Gs protein that connects G-protein coupled receptors <strong>of</strong><br />

various hormones (TSH, LH, FSH, PTH) with intracellular compounds for signalling cascades. Mutations in<br />

GNAS1 gene lead to: (1) decreased sensitivity <strong>of</strong> tissues normally responsive to PTH causing<br />

hypocalcemia and hyperphosphatemia; (2) decreased response to TSH leading to primary<br />

hypothyroidism. These metabolic disturbances can present with a combination <strong>of</strong> clinical findings<br />

including short stature, obesity, shortened fourth and fifth metacarpal bones due to premature closure<br />

<strong>of</strong> the epiphyses, and round face, i.e. Albright’s Hereditary Osteodystrophy (AHO). AHO phenotype<br />

presents in PHP subset Ia. Gene imprinting plays a role in its inheritance.The paternal GNAS1 gene is<br />

paternally imprinted (silenced) in the renal cortex. Metabolic findings <strong>of</strong> PHP become present only in<br />

patients who inherit a mutated allele from their mothers. It appears that our patient inherited a<br />

mutated maternal allele for GNAS1 which explains his combination <strong>of</strong> metabolic abnormalities and AHO<br />

phenotype (PHP type Ia).<br />

A RARE CAUSE OF RHABDOMYOLYSIS: DULOXETINE<br />

Namita Singh, MD; Rashmi Chandra, MBBS; Eric M Brown, MD<br />

INTRODUCTION:Duloxetine is a selective serotonin and norepinephrine reuptake inhibitor (SNRI) and is<br />

approved by the FDA for the treatment and maintenance <strong>of</strong> major depressive disorder. It has also been<br />

approved for the management <strong>of</strong> neuropathic pain associated with diabetic peripheral neuropathy,<br />

generalized anxiety disorder, fibromyalgia, and chronic musculoskeletal pain. Although potentially lifethreatening<br />

serotonin syndrome, depression/ suicidal ideation and hepatic failure have been wellpublished,<br />

there have been only few cases <strong>of</strong> duloxetine-induced rhabdomyolysis reported so far.<br />

CASE PRESENTATION: 63-year-old woman presented to the emergency room with altered mental<br />

status for 2 days duration; nausea and diffuse muscle pains for a week. Past medical history included<br />

hypertension, chronic obstructive pulmonary disorder, osteoporosis, chronic back pain, bipolar disorder<br />

and Alprazolam-induced psychosis. Her long-term medications were temazepam, sertraline, oxycodone,<br />

morphine, cyclobenzaprine, hydrochlorothiazide, irbesartan, metorpolol, Vitamin D and lansoprazole.<br />

Only recent medication change was addition <strong>of</strong> Duloxetine (Cymbalta) 2 weeks ago. On presentation,<br />

patient was tachycardic (PR 110/min), hypotensive (BP 66/38 mm Hg), easily arousable, however<br />

remained confused. Rest <strong>of</strong> the examination was benign. Laboratory tests showed acute renal failure<br />

(BUN 114mg/dL, Creatinine 13.6mg/dL with baseline 0.66mg/dL), and severe rhabdomyolysis (CPK<br />

10,320 U/L, Myoglobin 4,503 mcg/ml). The patient was admitted to intensive care unit and was treated<br />

with intravenous fluid resuscitation with bicarbonate-containing fluids. Psychiatry consult was requested<br />

and as per recommendations, duloxetine was discontinued. Following the discotinuation <strong>of</strong> duloxetine,<br />

her rhabdomyolysis and acute renal failure resolved over the subsequent several days. She improved<br />

gradually with aggressive fluid hydration and was discharged home in stable condition on day 10.<br />

DISCUSSION: The temporal fashion in which rhabdomyolysis and acute renal failure occurred within 2<br />

weeks <strong>of</strong> starting new therapy with duloxetine, without any other changes in the health status/<br />

medications, and improvement with discontinuation <strong>of</strong> the therapy, suggests duloxetine to be the<br />

etiology in our patient. During literature review, the author came across four cases <strong>of</strong> rhabdomyolysis<br />

caused by SNRIs (exclusive <strong>of</strong> serotonin syndrome). Duloxetine has been reported in two cases- one<br />

described with co-ingestion <strong>of</strong> alcohol, and the other in the setting <strong>of</strong> recent addition <strong>of</strong> quetiapine. One<br />

group has illustrated an interaction between citalopram and irinotecan leading to rhabdomyolysis. There<br />

is also an article reviewing three cases <strong>of</strong> rhabdomyolysis due to SSRIs and eccentric exercise. Some<br />

patient and physician groups have been reporting side-effects <strong>of</strong> duloxetine to FDA and several online<br />

sites. An internet website ehealthme.com states that as on November 17, 2011, Rhabdomyolysis<br />

constitutes 0.32% <strong>of</strong> the side-effects reported with Duloxetine. This information was based on 86<br />

reports from FDA and user community.<br />

The authors conclude that Duloxetine may cause severe rhabdomyolysis and clinicians should be aware<br />

<strong>of</strong> this adverse event. There should be all attempts to minimize its occurrence and identify it in early<br />

stages to prevent catastrophic consequences.<br />

The role <strong>of</strong> MTHFR 677TT genotype in a case <strong>of</strong> recurrent Thrombotic Thrombocytopenic Purpura<br />

(TTP)<br />

Uday C Lele, MD(Associate), Patricio Cabral, MD(Associate), Yutthapong Temtanakitpaisan,<br />

MD(Associate), MetroWest Medical Center, Framingham, MA.<br />

INTRODUCTION:Homozygous C677T mutation in the Methylentetrahydr<strong>of</strong>olate Reductase gene<br />

(MTHFR 677TT genotype) is an inherited thrombophilic risk factor which has been implicated in<br />

pathogenesis <strong>of</strong> multiple small-artery occlusions. Recent clinical studies suggest that the individuals<br />

carrying this genetic variant are at an increased manifestation risk and are predisposed for a more<br />

severe clinical course <strong>of</strong> TTP. We hereby report an intriguing case <strong>of</strong> a patient with MTHFR 677TT<br />

genotype presenting with recurrent episodes <strong>of</strong> TTP.<br />

CASE PRESENTATION: A 31 year old Hispanic woman presented to the Emergency Department (ED)<br />

with complaints <strong>of</strong> acute onset <strong>of</strong> dizziness and garbled speech. Patient had a history <strong>of</strong> two previous<br />

episodes <strong>of</strong> TTP associated with pregnancy which responded to multiple rounds <strong>of</strong> plasma exchange and<br />

high dose steroids. Her latest episode was six months ago. The initial laboratory results from ED showed<br />

a normal white blood cell count (9400/cu.mm), anemia (hematocrit 19.7%) and thrombocytopenia<br />

(6000/cu.mm). Schistocytes were identified on peripheral blood smear. Renal and liver function tests<br />

were normal. Serum Lactate dehydrogenase (LDH) level was elevated (1468 units/lit). Coagulation<br />

pr<strong>of</strong>ile and serum fibrinogen level were normal. Urine pregnancy test was negative. Computed<br />

Tomography <strong>of</strong> brain revealed no evidence <strong>of</strong> acute infarct or bleeding. Relapse <strong>of</strong> TTP was recognized<br />

and patient was treated with infusions <strong>of</strong> fresh frozen plasma and multiple rounds <strong>of</strong> plasma exchanges<br />

resulting in significant improvement in blood counts. Additional workup showed ADAMTS13 activity <strong>of</strong><br />

less than 5% and presence <strong>of</strong> ADAMTS13 inhibitory antibody (1.6 Inhibitory Units) suggesting an<br />

acquired TTP. Lupus anticoagulant, anti-dsDNA antibodies, as well as anti-phospholipid antibodies were<br />

negative. Due to recurrent episodes <strong>of</strong> TTP, a screen for genetic polymorphisms associated with<br />

thrombophilia was requested, which only disclosed MTHFR 677TT genotype status. Serum homocysteine<br />

level was also noted to be elevated at 19.5 micromol/litre. She was treated with four cycles <strong>of</strong> rituximab<br />

therapy prior to her discharge and was maintained on vitamin B complex therapy to avoid future TTP<br />

relapse.<br />

DISCUSSION: The exact pathomechanism that promotes microvascular thrombosis in presence <strong>of</strong> the<br />

MTHFR 677TT genotype has not yet been fully established. It has been suggested that the MTHFR 677TT<br />

genotype causes disruption <strong>of</strong> endothelial function by triggering the inflammatory response, by inducing<br />

a hypercoagulable state, and by promoting endothelial activation which altogether can lead to<br />

thrombosis <strong>of</strong> the arterial microvasculature. Therefore, in patients with recurrent episodes <strong>of</strong> TTP,<br />

judicious management <strong>of</strong> MTHFR 677TT genotype status is imperative as it may help in reducing future<br />

episodes <strong>of</strong> TTP by improving the overall endothelial function.<br />

A UNIQUE PRESENTATION OF SEPTIC THROMBOPHLEBITIS<br />

Denisa Bellani, DO J. Grant MD, K Lwin MD, H.Aroke MD.<br />

INTRODUCTION:This is a unique case presentation <strong>of</strong> septic thrombophlebitis in a young female with<br />

no risk factors and a normal vaginal delivery.<br />

CASE PRESENTATION: A 21 year old primigravid underwent normal vaginal delivery then on postpartum<br />

day # 7 presented with high grade fever, chills and right lower quadrant pain. She had<br />

intermittent fevers 104-107oF for two-three days prior to her emergency room visit. She denied nausea,<br />

vomiting, or change in bowel habit. Her vitals were significant for Tmax 103, HR 143, BP 124/45 Sat 95%<br />

on RA. The exam revealed an obese female in no apparent distress, with tachycardia, clear lungs and<br />

abdominal exam showing a post-gravid abdomen, s<strong>of</strong>t, non-tender and with bowel sounds present.<br />

There was no rebound, rigidity and no costovertebral angle tenderness. Laboratory data was significant<br />

for a white count 20.1, bandemia 15%, normal electrolytes, normal kidney function and mildly elevated<br />

AST 33 U/L ALT 40 U/L and Alk Phos 197. CT <strong>of</strong> the abdomen demonstrated right gonadal vein<br />

thrombosis with extension <strong>of</strong> the thrombosis into the inferior vena cava with prominent retroperitoneal<br />

inflammation, mild ureteral dilatation secondary to adjacent inflammation, prominent postpartum<br />

uterus and slight prominence <strong>of</strong> the right ovary. The patient diagnosed with sepsis was managed with<br />

fluid resuscitation <strong>of</strong> 3L normal saline and initial placement on Ceftriaxone 2 g daily, Vancomycin 1 g IV<br />

q12 hr, and Clindamycin 900 mg IV q8hr. Blood cultures revealed Fusobacterium 2/4 at which point the<br />

patient was transitioned to Piperacillin-Tazobactam 3.375 mg IV q6hr. For the treatment <strong>of</strong><br />

thrombophlebitis patient was placed on Enoxaparin 90 mg SQ BID. Patient became afebrile and was<br />

discharged with Augmentin 875 mg BID for a total <strong>of</strong> 28 day treatment along with Enoxaparin injections<br />

for 6 weeks.<br />

DISCUSSION: The overall incidence <strong>of</strong> septic pelvic thrombophlebitis is noted to be 1:3000 deliveries,<br />

with 1:9000 after vaginal deliveries and 1:800 after cesarean section. Patients present within 7 days <strong>of</strong><br />

delivery with abdominal pain on the side <strong>of</strong> thrombophlebitis. Right ovarian vein is the most commonly<br />

involved. Diagnostic criteria for septic thrombophlebitis include imaging studies: computed tomography<br />

(CT) scan or ultrasound or immediate defervescence following heparin therapy. Fibronopeptide A (FPA)<br />

is the first peptide cleaved from fibrinogen during thrombin mediated fibrin generation, levels greater<br />

than 14 ng/ml could confirm septic thrombophlebitis when missing imaging confirmation. Management<br />

involves ligation <strong>of</strong> both ovarian veins and inferior vena cava or heparin as an alternative effective<br />

treatment with the addition <strong>of</strong> antibiotics.<br />

INTRODUCTION:Cryoglubulinemia is the occasional presence <strong>of</strong> abnormal serum proteins in patients<br />

with autoimmune diseases, multiple myeloma, leukemia or certain forms <strong>of</strong> pneumonia, which result in<br />

hyperviscosity and tissue necrosis, potentially leading to limb amputation without early intervention.<br />

CASE PRESENTATION: 62 year old female with a history <strong>of</strong> hypertension and fibromyalgia presented to<br />

our tertiary care center for acutely worsening pain in her right foot after failed outpatient analgesic<br />

management. She reported constant pain, associated with a bluish discoloration <strong>of</strong> toes and swelling <strong>of</strong><br />

all digits. She had noticed a similar discoloration a year ago, exacerbated by cold temperatures.<br />

Extensive rheumatological workup was unremarkable, and trials <strong>of</strong> prednisone and nifedipine, though<br />

with initial relief, were not successful. She was admitted for pain control and limb evaluation for<br />

gangrene. On presentation, except for mild tachycardia, she was hemodynamically stable. She was<br />

found to have a cyanotic discoloration <strong>of</strong> her right toes with significant swelling <strong>of</strong> her second and fifth<br />

toes. There was coolness to touch along with pain to palpation. Her left foot was within normal limits.<br />

Good peripheral pulses were appreciated and sensation was intact. In addition, all <strong>of</strong> her fingers were<br />

swollen and tender. Livedo reticularis was present on both lower extremities.<br />

Initial labs were significant for leukocytosis 19.7 k/mm3, ESR 52 mm/hr, CRP 9.9 mg/dl, AST 239 units/L,<br />

ALT 374 units/L. The Vascular Surgeons were concerned for atherosclerotic emboli resulting in “blue toe<br />

syndrome,” for which the patient was started on aspirin and a statin. However, the leukocytosis, hand<br />

swelling, and rash could not be explained. Her Rheumatologist was consulted, and was concerned for a<br />

rheumatoid vasculitis, so repeat rheumatological workup was obtained.<br />

She continued to have pain in her right foot with worsening gangrene. Cryoglobulin level was positive<br />

with IgG kappa M spike on immun<strong>of</strong>ixation. Total IgG, IgA and IgM levels were low. Hepatitis C antibody<br />

was negative. She was diagnosed with Type 1 cryoglobulinemia with IgG kappa protein, and was started<br />

on IV cyclophosphamide, bortezomib and dexamethasone with improvement <strong>of</strong> the rash and swelling.<br />

She did, however, require eventual amputation <strong>of</strong> her right 2nd, 4th and 5th toes due to gangrene.<br />

DISCUSSION: Cryoglobulinemia is the presence <strong>of</strong> cryoglobulins (immunoglobulins that undergo<br />

precipitation at low temperatures) in the serum, causing systemic inflammation affecting the skin and<br />

joints. Three types <strong>of</strong> cryoglobulinemia have been identified. Type 1 does not have rheumatoid factor<br />

activity and is usually associated with lymphoma, Waldenstorm’s macroglobulinemia and multiple<br />

myeloma. Treatment depends on the type, severity <strong>of</strong> symptoms and degree <strong>of</strong> hyperviscosity. It usually<br />

responds to chemotherapy and plasmapharesis. Quick diagnosis and treatment are necessary to prevent<br />

limb ischemia or loss.<br />

Paraneoplastic Hyperthyroidism In A Patient With Extragonadal Germ Cell Tumor.<br />

Shihab Masrur, Jaime Solorzano, Quret-ul Quresh, Ning Fu, Sukhpal Mann<br />

INTRODUCTION: Familiarize with rare paraneoplastic hyperthyroidism associated with extragonadal<br />

germ cell tumor and its treatment. Extragonadal germ cell tumors (EGGCT) represent about 5% <strong>of</strong> all<br />

germ cell tumors. EGGCT syndromes are rare tumors that predominantly affect young males. Human<br />

Chorionic Gonadotropin (HCG) induced hyperthyroidism represents a rare paraneoplastic syndrome in<br />

HCG-secreting germ cell tumors. We report a case <strong>of</strong> young male patient with EGGCT and paraneoplastic<br />

hyperthyroidism.<br />

CASE PRESENTATION: A 46-year-old man was recently diagnosed with mixed EGGCT after extensive<br />

outpatient work up and a retroperitoneal biopsy presented with cough, dyspnea and progressive<br />

fatigue. Patient was treated symptomatically for respiratory failure due to pulmonary metastasis.<br />

Patient started to show improvement in two days but he was noticed to be increasingly fatigued and<br />

remained tachycardic. Physical exam revealed a pulse rate 116 per minute and respiratory rate 22 per<br />

minute with mild tremors without any other signs <strong>of</strong> hyperthyroidism. Lab data showed an elevated T4:<br />

4.0, low TSH: 0.01, very high LDH: 1422 and HCG: 281,267. He was successfully treated with Cisplatin<br />

based chemotherapy with normalization <strong>of</strong> his T4 and HCG: 3374.<br />

DISCUSSION: Incidence <strong>of</strong> paraneoplastic hyperthyroidism in extragonadal GCT is unknown. The<br />

incidence <strong>of</strong> hyperthyroidism in testicular germ cell tumor is 3.5%. The most accepted explanation <strong>of</strong><br />

hyperthyroidism is the weak TSH-like activity <strong>of</strong> HCG. In the absence <strong>of</strong> clinical signs <strong>of</strong> hyperthyroidism,<br />

treatment usually consists <strong>of</strong> specific chemotherapy directed toward tumor resulting in normalization <strong>of</strong><br />

thyroid function if HCG declines. Cisplatin based chemotherapy including etoposide, ifosfamide are used<br />

for treatment. The symptoms <strong>of</strong> hyperthyroidism also abate with return <strong>of</strong> HCG levels to normal.<br />

Overlapping thyrostatic treatment has also been recommended. Patients with elevated tumor<br />

biomarkers like HCG or metastatic disease have poor prognosis however with chemotherapy 5-year<br />

survival rates is about 50%. High-dose chemotherapy followed by autologous peripheral stem cell or<br />

autologous bone marrow support has also been investigated.<br />

CONCLUSION: Although rare, paraneoplastic hyperthyroid syndrome in EGGCT should be recognized<br />

for successful chemotherapy treatment. Further studies are warranted for incidence and prognosis.<br />

Rapose, MD Departments <strong>of</strong> Medicine, St. Vincent Hospital and the Reliant Medical Group, Worcester,<br />

MA<br />

INTRODUCTION: Abiotrophia defectiva is a part <strong>of</strong> normal oral flora. Endocarditis due to Abiotrophia<br />

species is a rare entity. It is <strong>of</strong>ten associated with negative blood cultures. Treatment failures<br />

and infection relapses are higher than in endocarditis caused by other viridians streptococci. Even<br />

though antibiotic guidelines are laid down, abiotrophia defectiva endocarditis is associated with high<br />

morbidity and mortality.<br />

CASE PRESENTATION: The patient is a 54-year-old lady admitted with left upper quadrant pain. A CT<br />

scan showed a splenic infarct. Trans-thoracic echocardiography showed a moderate sized aortic<br />

vegetation with aortic regurgitation. A transesophageal echocardiogram confirmed the vegetation.<br />

Blood cultures grew Abiotrophia defectiva in four out <strong>of</strong> four bottles. The patient was started on<br />

penicillin and gentamicin, but, unfortunately, developed gentamicin induced acute renal injury. Since<br />

she did not satisfy the criteria for aortic valve replacement, surgery was deferred. Based on the<br />

sensitivity pr<strong>of</strong>ile, treatment was switched to ceftriaxone. She completed 6 weeks <strong>of</strong> antibiotic therapy,<br />

but five months later returned with severe aortic insufficiency and systolic heart failure, with a drop in<br />

ejection fraction from 55% to 30%. Aortic valve replacement was undertaken. Valve microscopy showed<br />

gram positive cocci. The organism seen in the Gram stain was not recovered by culture. It is suspected<br />

that organism lost viability. After the surgery the patient’s cardiac function improved, and she<br />

completed another six weeks <strong>of</strong> ceftriaxone.<br />

DISCUSSION: Abiotrophia defectiva, previously referred to as nutritionally variant streptococci, is a rare<br />

and fastidious organism which is very resistant to antibiotics. Nutritionally variant streptococci species<br />

have shown great tolerance to penicillin. Our case demonstrates the scenario where the patient<br />

required valve replacement in spite <strong>of</strong> in-vitro sensitivity to ceftriaxone. The experience from this case<br />

as well as others in literature strongly suggests the need for early surgical intervention when<br />

Abiotrophia defectiva endocarditis is encountered. Even though current case do not completely indicate<br />

treatment failure , it adds to the literature about treatment difficulty in abiotrophia defectiva<br />

endocarditis. It also shows the need for more organism specific surgical guidelines for endocarditis<br />

management.<br />

Posterior Reversible Encephalopathy Syndrome Associated With Para-influenza Virus Infection. Under So<br />

Much Pressure!<br />

Owolabi Ogunneye, MD, MRCP. Jaime Hernandez, MD James Canoy, MD Daniel Landry, DO<br />

INTRODUCTION: Posterior reversible encephalopathy syndrome is a clinicoradiological entity first<br />

described by Hinchey in 1996. The common clinical features are headache, seizures, visual changes and<br />

altered mental status. MRI allows more precise characterization and recognition <strong>of</strong> PRES than CT(1).<br />

CASE PRESENTATION: A 54year-old Caucasian female presented with uncontrolled hypertension and<br />

new-onset seizures. Five days before presentation, she developed generalized headache and blurring <strong>of</strong><br />

vision and she visited her closest ED, which found her hypertensive with a SBP <strong>of</strong> 260 mmHg. She was<br />

treated with analgesics and parenteral antihypertensive medications with partial improvement <strong>of</strong><br />

symptoms and was subsequently discharged to her home in rural Western Massachusetts. 24 hours<br />

before admission, she again visited her local ED complaining <strong>of</strong> similar symptoms. Blood pressure<br />

recorded at the time was 260/160 mmHg. She was again treated with IV narcotics and<br />

antihypertensives, however while being treated she developed confusion and the decision was made to<br />

transfer the patient to our hospital. On route she had an episode <strong>of</strong> tonic-clonic seizure activity lasting 3-<br />

4 minutes. Her medical history was notable for hypertension, SLE, ESRD on peritoneal dialysis. Her<br />

initial laboratory data was relevant for leucocytosis <strong>of</strong> 16,500. She underwent CT scan <strong>of</strong> the brain and<br />

LP for CSF analysis which was unremarkable. Empiric treatment for viral and bacterial meningitis with IV<br />

acyclovir, vancomycin and ceftriaxone followed. Blood and CSF cultures were unremarkable. On ICU day<br />

2, the patient developed a fever <strong>of</strong> 102.0 F and a nasopharyngeal direct fluorescent antigen test was<br />

positive for Para-influenza virus confirmed with viral cultures for Para-influenza Type 3. Lupus activity<br />

studies showed normal C3/C4 levels, elevated Complement 50 levels >60. An MRI <strong>of</strong> the brain without<br />

contrast was performed on ICU day 2 revealing changes in the posterior hemispheres.<br />

DISCUSSION: A case has been reported <strong>of</strong> an association between influenza A virus and PRES(2). Our<br />

case is unique in that Para-influenza virus infection has not been reported in the literature as an<br />

association with development <strong>of</strong> PRES. Our patient was treated symptomatically, with particular<br />

attention given to aggressive blood pressure control. She recovered fully with no residual neurological<br />

deficit. We postulate that our patient experienced an episode <strong>of</strong> coexistent hypertensive-SLE and<br />

infection-associated PRES precipitated by a combination <strong>of</strong> uncontrolled hypertension and Parainfluenza<br />

virus type 3 infection. Both associations favor the contribution <strong>of</strong> endothelial dysfunction.<br />

A Rare Case Of Cerebellar Abscess Secondary To Peptostreptococcus Sp. from An Odontogenic Source.<br />

The Way To A Man’s Brain!<br />

Owolabi Ogunneye, MD, MRCP Eric Churchill, MD, MPH.<br />

INTRODUCTION: Cerebellar abscesses account for 9-28% <strong>of</strong> all brain abscesses and 85-99% <strong>of</strong> cases<br />

result from contiguous spread <strong>of</strong> infection from an ipsilateral ear or sinus source (1). Advances in<br />

neuroimaging techniques as well as the introduction <strong>of</strong> more effective antibiotics have reduced the<br />

mortality <strong>of</strong> brain abscesses to 0-24% (2).<br />

CASE PRESENTATION: An immunocompetent 41year old Caucasian female was admitted with 2week<br />

history <strong>of</strong> neck pain/stiffness associated with occipital headache radiating to the frontal region. Five<br />

days prior to admission, she presented to the ER <strong>of</strong> this facility with worsening symptoms and was<br />

discharged to her home in rural western Massachusetts after Brain CT and lumbar puncture were<br />

unremarkable. On the day <strong>of</strong> admission, she developed diplopia while driving, associated with<br />

intractable nausea and vomiting. She smokes 1 pack cigarettes/day and drinks alcoholic beverages<br />

socially. Physical examination revealed a febrile patient, temperature (39 C). Intraoral clinical and<br />

panorex imaging revealed the presence <strong>of</strong> generalised periodontal disease, multiple dental caries and<br />

loose teeth. Cardiac, Respiratory and Integumentary system examinations were unremarkable.<br />

Neurological examination revealed an awake, alert and oriented patient with no focal weakness.<br />

An MRI <strong>of</strong> the brain with contrast at the time <strong>of</strong> admission revealed a left cerebellum abscess and a<br />

small left cavernous sinus abscess with septic thrombophlebitis. She was empirically started on<br />

vancomycin (1gm IV 8qhrs) and ceftriaxone(2gm IV q24hrs) pending results <strong>of</strong> blood cultures and the<br />

dentist was consulted for extraction <strong>of</strong> decaying teeth. Two days after admission, she became<br />

unresponsive prompting an ICU transfer. Head CT revealed obstructive hydrocephalus. A right frontal<br />

external ventricular drain was placed for decompression. CSF studies showed elevated protein, with low<br />

glucose. A set <strong>of</strong> two blood cultures drawn on admission returned positive for Peptostreptococcus Spp.<br />

The patient was discharged after 2weeks inpatient care. She received a 12-week course <strong>of</strong> antibiotic<br />

therapy. All her symptoms resolved completely. She remained asymptomatic with no residual deficit.<br />

DISCUSSION: This case is unique due to the location <strong>of</strong> the abscesses, the patient’s immune status and<br />

the possible odontogenic source <strong>of</strong> the infection. Dental pathogens from oral infection could enter the<br />

brain through either through a hematological route (facial, angular, ophthalmic artery, spread through<br />

the cavernous sinus as in our patient) (2). Given our patient’s generalized periodontal disease, positive<br />

blood culture for an oral pathogen “Peptostreptococcus”, cavernous sinus abscess and the lack <strong>of</strong> an<br />

alternative source <strong>of</strong> infection, we postulate that her cerebellar abscess arose via spread through the<br />

left cavernous sinus.<br />

Statin Interactions: Do we know enough?<br />

INTRODUCTION: Rhabdomyolysis is a potentially life-threatening condition which can result in acute<br />

kidney injury (AKI). Several hydroxymethylglutaryl coenzyme A (HMG-CoA) reductase inhibitors (statins)<br />

have been associated with a rise in creatine phosphokinase (CPK). Rhabdomyolysis leading to AKI is less<br />

common. We report a case <strong>of</strong> severe muscle injury resulting in AKI that occurred as a result <strong>of</strong> a<br />

simvastatin-antibiotic interaction.<br />

CASE PRESENTATION: A 69 year old gentleman was seen by his primary care physician for epigastric<br />

discomfort and was diagnosed with Helicobacter pylori gastritis. Since 2006, he had been on simvastatin<br />

80 mg daily, ezetimibe 10 mg once daily and gemfibrozil 600 mg twice daily for hyperlipidemia. He was<br />

started on triple therapy with amoxicillin, lansoprazole and clarithromycin. One week later, he<br />

developed extreme fatigue and muscle aches. He also complained <strong>of</strong> muscle weakness, which<br />

progressed to the point where he required assistance with ambulation. His past medical history was<br />

significant for chronic kidney disease (stage III, estimated glomerular filtration rate 52.6 ml/min),<br />

coronary artery disease, hypertension, and hyperlipidemia. Physical examination was remarkable for<br />

proximal muscle weakness and tenderness. Blood urea nitrogen was 100 mg/dL, serum creatinine 2.72<br />

mg/dL, CPK 17364 U/L. His urine was positive for myoglobin and his urine sediment showed many<br />

granular casts but few red cells. His peak serum creatinine was 2.72 mg/dL and his peak CPK was 17525<br />

U/L. With the discontinuation <strong>of</strong> clarithromycin, simvastatin and gemfibrozil and with supportive care,<br />

his muscle enzymes and renal function gradually improved.<br />

DISCUSSION: Clarithromycin is known to be a potent inhibitor <strong>of</strong> CYP3A4, the major enzyme<br />

responsible for simvastatin metabolism. Gemfibrozil is an organic anion-transporting polypeptide (OATP)<br />

1B1 inhibitor, which interferes with the hepatocyte uptake <strong>of</strong> simvastatin, and also interferes with statin<br />

glucuronidation, a step necessary for statin elimination. These drugs, when combined with a maximal<br />

dose <strong>of</strong> simvastatin (80 mg/day), resulted in a rise in statin levels and the risk <strong>of</strong> muscle injury. By<br />

comparison, rosuvastatin, pitavastatin, and pravastatin have minimal hepatic metabolism and<br />

fluvastatin is metabolized by CYP2C9; hence they are less susceptible than atorvastatin, lovastatin, and<br />

simvastatin to CYP3A4 interactions.<br />

Our observations confirm that high dose simvastatin should be used with caution given its risk <strong>of</strong> causing<br />

rhabdomyolysis, particularly in combination with CYP3A4 inhibitors and gemfibrozil. Alternate therapy<br />

with rosuvastatin, pitavastatin, or pravastatin, lowering the statin dose, or temporary discontinuation <strong>of</strong><br />

the statin should be considered in this setting.<br />

Treatment <strong>of</strong> AA Amyloidosis in Psoriatic Arthritis with Etanercept<br />

; Srijana Ranjit, MD (Associate), William Gaines, MD, Robert Yood, MD, FACP Departments <strong>of</strong> Medicine,<br />

St. Vincent Hospital and the Reliant Medical GroupFallon Clinic, Worcester, MA<br />

INTRODUCTION:Secondary AA amyloidosis (SAA) is an uncommon complication <strong>of</strong> chronic<br />

inflammatory diseases, including inflammatory arthritis. We present a patient with amyloidosis<br />

secondary to poorly controlled psoriatic arthritis who responded to treatment with a tumor necrosis<br />

factor (TNF) inhibitor (etanercept).<br />

CASE PRESENTATION: A 67 year-old man with a past medical history <strong>of</strong> hypertension, hyperlipidemia,<br />

and hypothyroidism was diagnosed with polyarticular psoriatic arthritis over 25 years ago. His arthritis<br />

was poorly controlled despite various treatments, including intramuscular gold, sulfasalazine, and<br />

methotrexate. The patient self-treated with multiple complementary and alternative medications. Anti-<br />

TNF treatment was considered in 2003 but not given because at that time the patient was undergoing<br />

treatment for metastatic small cell lung cancer. He was maintained on low dose prednisone with poor<br />

control <strong>of</strong> his arthritis.<br />

In November 2004, about 20 years after the onset <strong>of</strong> arthritis, routine urinalysis documented<br />

proteinuria; urinalysis 6 months earlier was normal. His renal function deteriorated with serum<br />

creatinine increasing to 1.6 mg/dL. A random urine protein creatinine ratio was 7.8. An abdominal fat<br />

pad aspirate was negative for amyloid, but a renal biopsy with immun<strong>of</strong>luorescence microscopy in April<br />

2005 documented AA amyloidosis. Etanercept was started June 2005 with dramatic improvement <strong>of</strong> his<br />

psoriasis, synovitis, and renal disease within 6 weeks. His urinary protein creatinine ratio decreased to<br />

2.0. His sedimentation rate decreased from 126 mm/hr prior to etanercept therapy to 69 one year later<br />

and 23 after 2 years <strong>of</strong> treatment. Etanercept was continued and in June 2011 his serum creatinine was<br />

1.01 mg/dL and random urine protein creatinine ratio 0.6.<br />

DISCUSSION: Although there are studies showing use <strong>of</strong> TNF inhibitors to treat AA amyloidosis<br />

secondary to rheumatoid arthritis, there is little information on the use <strong>of</strong> these drugs in the treatment<br />

<strong>of</strong> AA amyloidosis secondary to psoriatic arthritis. Treatment <strong>of</strong> AA amyloidosis secondary to<br />

rheumatoid arthritis has led to rapid improvement <strong>of</strong> proteinuria and stabilization <strong>of</strong> renal function. The<br />

improvement in renal function is likely secondary to suppression <strong>of</strong> inflammation which triggers SAA.<br />

Our patient had a dramatic response to etanercept with marked improvement in his psoriasis, resolution<br />

<strong>of</strong> his synovitis, normalization <strong>of</strong> his serum creatinine and near-resolution <strong>of</strong> his proteinuria. He<br />

continues etanercept with stable renal function after more than 6 years and demonstrates that<br />

etanercept is a promising treatment <strong>of</strong> AA amyloidosis secondary to psoriatic arthritis.<br />

Steroid-resistant Asthma Exacerbation And A Paroxysmal Cough<br />

Renee K Rutledge, MD<br />

INTRODUCTION:The clinical disease known as pertussis was first described over 400 years<br />

ago. Historically and epidemiologically an important disease, the number <strong>of</strong> cases dwindled in the late<br />

20 th century due to widespread use <strong>of</strong> whole cell vaccines against the causative agent, Bordetella<br />

pertussis. Paradoxically, this success has led to waning immunity in adults coupled with a major<br />

resurgence, exemplified by the 2010 California outbreak <strong>of</strong> 9,143 cases -- the largest since 1947.<br />

CASE PRESENTATION: A 64 year-old man with past medical history <strong>of</strong> previously well-controlled adultonset<br />

asthma presented for the third time reporting dyspnea, wheezing, and cough. On initial<br />

presentation he reported two weeks <strong>of</strong> cough productive <strong>of</strong> clear to yellow sputum, with two days <strong>of</strong><br />

wheezing and nocturnal dyspnea. He denied fevers, chills, rhinorrhea, sore throat, or sinus congestion.<br />

Chest radiograph excluded infiltrates, so he was treated with albuterol/ipratropium nebulizer, IV<br />

methylprednisolone and discharged on prednisone taper. Three days later he re-presented with a dry<br />

cough occurring in “fits,” despite corticosteroids and inhaler, and then presented for a third time with<br />

persistent coughing fits that were interrupting sleeping and eating (though without post-tussive<br />

emesis). He received two albuterol/ipratropium nebulizer treatments in the Emergency Department<br />

that provoked atrial flutter and prompted hospital admission. On admission he was afebrile,<br />

normotensive, and in atrial flutter with variable block with a heart rate <strong>of</strong> 80 beats per minute. Lung<br />

exam revealed significant wheezing, comfortable breathing at a rate <strong>of</strong> 16, and oxygen saturation >95%<br />

on room air. Shortly after arrival an explosive coughing fit was witnessed during which he became<br />

diaphoretic, developed facial erythema and manifested a marked inspiratory whoop. The patient denied<br />

ever having received a Tdap shot or any tetanus immunization in the past decade. Droplet precautions<br />

were initiated, empiric azithromycin started, posterior nasopharyngeal swab obtained for Bordetella<br />

pertussis, and serology sent to the state laboratory. The patient converted to normal sinus rhythm after<br />

administration <strong>of</strong> diltiazem, and cough and overall respiratory status improved over three days.<br />

Approximately one week post discharge, the Massachusetts State Laboratory confirmed positive<br />

pertussis serology. In the absence <strong>of</strong> Tdap vaccination in the prior three years, this result is reported as a<br />

positive case <strong>of</strong> pertussis in Massachusetts.<br />

DISCUSSION: While a significant number <strong>of</strong> adult patients with cough greater than 7 days test positive<br />

for pertussis in studies, few manifest the classic whoop. In addition, this case emphasizes the need to<br />

continually re-evaluate diagnoses and treatment plans: multiple presentations for the same complaint<br />

should always prompt internists to reconsider their differential diagnoses and previously disregarded<br />

clinical clues. Fortuitously, in this case, atrial flutter prompted admission and provided physicians the<br />

opportunity to witness the classic pertussis whoop, establishing the diagnosis <strong>of</strong> this persistent cough.<br />

Note: Patient consented for video recording <strong>of</strong> a whooping episode, which the author has in electronic<br />

format.<br />

An Unusual Case <strong>of</strong> a Cyclic Skin Rash<br />

Praveen Sudhindra, MBBS George Abraham, MD, MPH Jennifer Sargent, DO<br />

INTRODUCTION: Recurring rashes have many etiologies and may pose a management challenge. We<br />

report a patient who presented with chronic, recurrent rash <strong>of</strong> a very unusual cause.<br />

CASE PRESENTATION: A 41 year old female with a history <strong>of</strong> poorly controlled diabetes mellitus<br />

presented with 3 days <strong>of</strong> fever and chills, along with redness, pain and discharge involving her left<br />

breast. Initial physical examination was significant for erythema and serous discharge from the skin over<br />

her left breast, along with tender left axillary lymphadenopathy. She was admitted for treatment <strong>of</strong><br />

presumed cellulitis with IV daptomycin. Over the next couple <strong>of</strong> days she developed a diffuse,<br />

erythematous and pruritic rash with vesicles and urticarial plaques involving the trunk, arms and legs.<br />

A diagnosis <strong>of</strong> dishydrotic eczema was made to explain the new rash. She was discharged home on<br />

tapering doses <strong>of</strong> steroids and IV daptomycin for what was thought to be cellulitis secondary to chronic<br />

eczema.<br />

She was seen in follow up at the infectious disease clinic ten days following discharge. Upon<br />

further investigation <strong>of</strong> the rash history we found a cyclical, self limiting pattern <strong>of</strong> her rash since she<br />

was 14 years old. The rash usually recurred a few days prior to menses and would subside a couple <strong>of</strong><br />

days afterward. Furthermore, the rash developed during her hospitalization was consistent with her<br />

usual pattern. She had undergone skin biopsies in the past which were inconclusive. She was treated<br />

with steroid tapers on multiple occasions with temporary relief.<br />

Given the cyclical nature <strong>of</strong> the rash, the possibility <strong>of</strong> Autoimmune Progesterone Dermatitis (AIPD) was<br />

considered, and the patient was tested with a challenge <strong>of</strong> 0.1ml <strong>of</strong> intradermal medroxyprogesterone.<br />

There was an immediate wheal response to the injection with subsequent induration 72 hours later. She<br />

was started on oral contraceptives with an aim to reduce exposure to progesterone by suppressing her<br />

ovulation cycle. She has remained symptom free for seven months, with only one flare since starting<br />

treatment.<br />

DISCUSSION: AIPD is a rare condition which requires the following diagnostic components: a) A history<br />

<strong>of</strong> a perimenstrual cyclic rash; b) Immediate and/or delayed hypersensitivity response to intradermal<br />

progesterone; c) Resolution <strong>of</strong> the rash by inhibiting ovulation.<br />

Should the patient have recurrent flares on oral contraceptives, the next line <strong>of</strong> treatment involves<br />

GnRH analogues, and ultimately, oopherectomy.<br />

Currently there are about 60-70 reported cases <strong>of</strong> AIPD in the literature. Internists should be mindful <strong>of</strong><br />

the fact that recurrent perimenstrual rashes might be secondary to progesterone dermatitis, and<br />

inhibiting the hypothalamic-pituitary-ovarian cycle may cure patients <strong>of</strong> the disease.<br />

What's In A Rash?: Follicular Non-Hodgkins Lymphoma Presenting as Paraneoplastic Pemphigus<br />

Cristina T De Castro-Dela Cruz, MD<br />

INTRODUCTION: Paraneoplastic pemphigus is a rare autoimmune blistering mucocutaneous disease<br />

that is frequently associated with malignancy, especially lymphoreticular cancer.<br />

CASE PRESENTATION: A 63 year old man was admitted with a progressive blistering rash after a skin<br />

biopsy was read as erytheme multiforme. He reported a one-month history <strong>of</strong> oral lesions followed by<br />

blistering skin lesions which started after initiation <strong>of</strong> medications for lower extremity edema. He also<br />

experienced dysphagia and a 20- pound weight loss. He was evaluated by a dermatologist, and a skin<br />

biopsy was done after which he was started on oral prednisone. Despite this, his lesions had continued<br />

to progress and thus he was admitted.<br />

Except for a slight lymphopenia, blood count and metabolic pr<strong>of</strong>ile was normal. Because <strong>of</strong> the concern<br />

for Stevens Johnsons Syndrome he was evaluated by an allergist and started on high dose intravenous<br />

immunoglobulin. Despite treatment, his vesicobullous eruptions evolved and and covered more <strong>of</strong> his<br />

body surface. He developed fevers up to 39°C and there was concern that infection was contributing to<br />

his illness. The infectious disease service was consulted. Although no source <strong>of</strong> infection was identified,<br />

Gentamicin was started. He developed respiratory insufficiency, chest roentgen revealed a pleural<br />

effusion. Computerized tomography showed a moderate pleural effusion, ascites in the upper<br />

abdomen, and an extensive s<strong>of</strong>t tissue mass near the pancreas, central mesentery and retroperitoneum,<br />

with diffuse adenopathy, concerning for lymphoma. CT scan <strong>of</strong> the abdomen and pelvis was performed,<br />

showing a 10cm x 17cm confluent nodal mass within the root <strong>of</strong> the small mesentery. Tissue biopsy<br />

confirmed the diagnosis <strong>of</strong> low-grade follicular lymphoma. A blood sample was sent for anti-desmoglein<br />

antibodies 1 & 3 titers, which came back positive. His skin lesions were attributed to paraneoplastic<br />

pemphigus. Estimated area <strong>of</strong> skin involvement exceeded 90% <strong>of</strong> body surface area.<br />

He was started on Rituximab but developed a hypotensive infusion reaction necessitating transfer to the<br />

medical intensive care unit. Plasmapheresis was initiated and he was given cyclophosphamide,<br />

vincristine and prednisone. The patient continued to deteriorate, developed Pseudomonas skin<br />

infection, and he needed to be intubated for respiratory failure with associated hospital acquired<br />

aspiration pneumonia. The patient expired a few days later.<br />

DISCUSSION: We report a case <strong>of</strong> paraneoplastic pemphigus, which presented as the first sign <strong>of</strong><br />

follicular lymphoma. The possibility <strong>of</strong> PNP should be considered when a patient presents with<br />

significant oral ulcers and diffuse blistering regardless <strong>of</strong> a known malignancy. The diagnosis is<br />

established with measurement <strong>of</strong> anti-plakin or anti-desmoglein auto antibody titers, skin biopsy with a<br />

histopathology and immun<strong>of</strong>luorescence. Treatment with corticosteroids is first line but there are<br />

newer modalities including rituximab and plasmapheresis. Thus far despite novel treatments the<br />

mortality rate <strong>of</strong> paraneoplastic pemphigus is still very high.<br />

Takotsubo Cardiomyopathy (Sad Heart) Secondary to Atrial Fibrillation Cardioversion<br />

Mershed Alsamara, MD Yazan Khouri, MD. Reema Hasan, MD. Shukri David, MD<br />

INTRODUCTION: Study:<br />

This is a case <strong>of</strong> a patient presented with Takotsubo Cardiomyopathy few days after electrical<br />

cardioversion for atrial fibrillation<br />

Objective:<br />

This case presents another trigger for Takotsubo which is a electrical cardioversion.<br />

Literature talks about precipitants like emotional and physical stressors; including death, trauma,<br />

surprising event, cocaine use and stress test. There is no case reported about Takostusbo as a result <strong>of</strong><br />

atrial fibrillation.<br />

Cardiomyopathy after cardioversion with normal coronary arteries was suggestive <strong>of</strong> induced<br />

dysfunction <strong>of</strong> the heart muscle.<br />

CASE PRESENTATION: Case DISCUSSION: 81 Y/O African <strong>American</strong> Female presented to ER<br />

complaining <strong>of</strong> new onset <strong>of</strong> shortness <strong>of</strong> breath, started the same morning, no chest pain, no nausea or<br />

diaphoresis.<br />

Patient was discharged from the hospital the day before after getting an electrical cardio-version <strong>of</strong><br />

atrial fibrillation.<br />

In the ER patient was hypoxic, Chest X- ray was ordered showing pulmonary edema. ECG was done<br />

showing ST elevation, cardiac enzymes came back positive; 2D echo showing severe systolic impairment,<br />

akinesis in the intra ventricular septum, anterior wall, apex, mid and inferior wall, EF 20%. An old echo<br />

from 2 months was available which showed normal LV with EF 60% and mild right atrial enlargement.<br />

Patient was taken for left heart catheterization which showed non significant coronary arteries disease<br />

with severely impaired LV systolic function, ballooning <strong>of</strong> the anterior wall consistent with (Tokotsubo).<br />

Patient was treated with BB, ACE, CCB and diuresis.<br />

Patient got another Echo before discharge which is showed improved LV contractility and EF <strong>of</strong> 30%.<br />

DISCUSSION: This case presents Takotsubo cardiomyopathy after electrical cardioversion <strong>of</strong> atrial<br />

fibrillation. This patient fits the picture <strong>of</strong> Takotsubo; cardiomyopathy after a stressful medical<br />

intervention. No case reports exist in the literature about Takotsubo after cardioversion<br />

Coagulopathy from dabigatran in patient with ESRD - Should INR monitoring be totally neglected with<br />

dabigatran?<br />

In Chul An, DO Second Author: Abrar Sayeed, MD Third Author: Heather S. Laird-Fick, MD,MPH,FACP<br />

INTRODUCTION: Dabigatran is an oral direct thrombin inhibitor which has been approved for<br />

prophylaxis <strong>of</strong> stroke in patients with atrial fibrillation. Excitement over the drug is driven by two major<br />

benefits. First, it is more effective than warfarin, without an increased bleeding risk. Second, its<br />

normally predictable pharmacokinetics obviate the need for INR monitoring and dose<br />

adjustment. Some patients may have altered pharmacokinetics, however, thereby altering the riskbenefit<br />

ration <strong>of</strong> treatment. We present such a case.<br />

CASE PRESENTATION: A 58 year old Caucasian male with history <strong>of</strong> recurrent paroxysmal atrial<br />

fibrillation status post pacemaker and end-stage renal disease on hemodialysis came to the Emergency<br />

Department with complaints <strong>of</strong> nose bleed. He was started on dabigatran 150 mg twice a day about 4<br />

months ago as an outpatient by his cardiologist. He has had frequent nosebleeds for two months. The<br />

day <strong>of</strong> presentation, the patient awoke to find himself in a pool <strong>of</strong> blood. His international normalized<br />

ration(INR) was 8.8 and activated partial thromboplastin time(aPTT) 105.7, otherwise all labs were<br />

unremarkable including liver function test. He did not miss any <strong>of</strong> his hemodialysis sessions.<br />

DISCUSSION: Dabigatran is contraindicated in patients with severe kidney insufficiency as it is<br />

predominantly excreted via the kidney (~80%). A reduced dose (75mg twice a day) is recommended for<br />

patients with mild to moderate kidney insufficiency (GFR 30-60). As dabigatran directly inhibits prothrombin<br />

to thrombin conversion, both intrinsic and extrinsic coagulation pathways are involved and<br />

can contribute to coagulopathy. Despite the studies showing only mild increase <strong>of</strong> aPTT and PT/INR with<br />

patients receiving dabigatran, closer monitoring may be reasonable in patients with renal insufficiency<br />

as pharmacokinetics may be less predictable.<br />

Despite predictable pharmacokinetics with dabigatran, it should be avoided in patients with severe<br />

kidney insufficiency. Decreased renal clearance can cause coagulopathy and significant bleeding. More<br />

studies are warranted looking at relationship <strong>of</strong> renal impairment and coagulation assays.<br />

thromboembolic events. Screening for factor VIII in a patient with arterial or venous thromboembolism<br />

is not a common practice.<br />

CASE PRESENTATION: A sixty two year old African <strong>American</strong> female was brought to the ED after she<br />

collapsed. She was found out to be in pulseless electrical activity, resuscitated and admitted to the<br />

intensive care unit. CT scan showed bilateral pulmonary emboli. She was started on heparin drip.<br />

Bilateral lower extremity duplex was negative for deep venous thrombosis. Hypercoagulable work up<br />

including protein C, protein S, anti thrombin, anticardiolipin antibody, lupus anticoagulant, factor V<br />

Leiden and factor VIII were obtained during her prolonged hospital stay. Factor VIII alone was found out<br />

to be elevated at 319.3% (normal 50-150%). Patient later gave history <strong>of</strong> 5 prior episodes <strong>of</strong> venous<br />

thromboembolism, and had been on 6-12 months <strong>of</strong> warfarin each time. Many first degree relatives<br />

were on warfarin. Patient was eventually discharged on warfarin with recommendations to continue it<br />

lifelong. In the following few months, we have encountered two more African <strong>American</strong> women who<br />

presented with pulmonary embolisms were found out to have isolated factor VIII elevation.<br />

DISCUSSION: Elevated factor VIII level (>150%) is now well documented to be one <strong>of</strong> the<br />

hypercoagulable states. There is a dose response relationship between the level <strong>of</strong> factor VIII and risk <strong>of</strong><br />

venous thromboembolism. It is associated with both venous and arterial thromboembolism. High body<br />

mass index, high blood glucose levels, elevated vWF levels and Non O blood group might affect factor<br />

VIII levels. First degree relatives <strong>of</strong> an affected individual are at high risk <strong>of</strong> developing venous<br />

thromboembolism. Risk level varies in different races, and women are at higher risk. The genetic<br />

determinants <strong>of</strong> elevated factor VIII are not yet identified. The intensity and duration <strong>of</strong> therapy with<br />

warfarin has not yet been definitely determined, and it is also unknown whether first degree relatives<br />

have to be screened. Importance <strong>of</strong> borderline elevation <strong>of</strong> factor VIII in acute settings is still debatable.<br />

Conclusion: Isolated factor VIII elevation is a significant risk factor for developing recurrent<br />

thromboembolic events resulting in severe consequences. Potentiality <strong>of</strong> factor VIII might be<br />

undermined. Importance <strong>of</strong> including factor VIII activity in hypercoagulable work-up needs to be<br />

established. Patients with venous thromboembolism and elevated factor VIII levels may need long-term<br />

anticoagulation. Further research in understanding the potentiality <strong>of</strong> factor VIII is indicated.<br />

Spontaneous Splenic Rupture from Undiagnosed Histoplasmosis<br />

Amal Ashraf, MD Second Author: Mimi Emig, MD, FACP<br />

INTRODUCTION:Histoplasmosis is the most prevalent endemic mycosis in the US. Dissemination to the<br />

reticuloendothelial system can occur, particularly in immunocompromised hosts. Dissemination has<br />

been reported with the use <strong>of</strong> biologic chemotherapeutic agents, but not with standard<br />

chemotherapy. In the spleen, Histoplasma can cause enlargement as well as infarcts. Atraumatic<br />

splenic rupture from Histoplasma is highly unusual. We describe a case <strong>of</strong> unsuspected disseminated<br />

histoplasmosis with an uncommon and potentially fatal presentation<br />

CASE PRESENTATION: A 43 year old man presented with 2 months <strong>of</strong> chest pain. CT chest showed an<br />

8cm upper lobe mass with chest wall invasion. Percutaneous biopsy demonstrated non-small cell lung<br />

cancer with angiolymphatic invasion. PET CT demonstrated avid FDG uptake in the lung mass, without<br />

abnormal uptake at any other site. The patient was started on taxol / carboplatin, but had increased<br />

size <strong>of</strong> the lung mass after 2 cycles. He complained <strong>of</strong> fatigue, night sweats, and weight loss, which were<br />

attributed to his lung cancer and chemotherapy. He underwent resection <strong>of</strong> the lung mass and involved<br />

chest wall 2 ½ months after his initial diagnosis. Pathology showed large cell lung cancer with rhabdoid<br />

phenotype, with chest wall invasion. Mediastinal lymph nodes showed no malignancy but did show<br />

changes <strong>of</strong> Histoplasma. On post-op day 5, the patient developed hemorrhagic shock and acute<br />

abdominal pain and a 3gm drop in hemoglobin. CT scan showed an enlarged heterogeneous spleen,<br />

likely due to a splenic hematoma with hemoperitoneum. He underwent emergent exploratory<br />

laparotomy where he was found to have complete disruption <strong>of</strong> the spleen, 2.5 liters <strong>of</strong> old blood within<br />

the abdominal cavity and a large amount <strong>of</strong> clot around the spleen. Emergent splenectomy was<br />

performed. Pathology from the spleen demonstrated disrupted spleen with abundant blood clot and<br />

degenerating granulomata containing Histoplasma. Subsequent urinary Histoplasma antigen and serum<br />

Histoplasma antibody were both negative. HIV ELISA was also negative. Due to plans for further<br />

chemotherapy, he was started on oral itraconazole<br />

DISCUSSION: Undiagnosed histoplasmosis caused acute splenic rupture in our patient; we propose that<br />

his recent chemotherapy resulted in dissemination <strong>of</strong> his quiescent infection. One case <strong>of</strong> disseminated<br />

Histoplasmosis causing splenic rupture was previously described in a patient with rheumatoid arthritis<br />

on Infliximab and methotrexate. Another case <strong>of</strong> histoplasma reactivation in a patient with CLL receiving<br />

fludarabine and alemtuzumab causing haemophagocytic syndrome has been reported. To our best<br />

knowledge, this would be the second reported case <strong>of</strong> Histoplasma causing splenic rupture. Reactivation<br />

<strong>of</strong> Histoplasma by biologic agents has been widely reported. There is limited data on Histoplasma<br />

reactivation in cancer patients receiving standard chemotherapy. Further study is needed to determine<br />

whether screening for Histoplasma in endemic areas can prevent severe sequelae in patients receiving<br />

chemotherapy or biologic agents<br />

Stop! Think, and decide? A rare but life threatening effect <strong>of</strong> dabigatran<br />

Quratulain Aziz, MBBS. Abdur Rehman, MD. Nasir Khan, MD.<br />

INTRODUCTION:Dabigatran etexilate is a direct thrombin inhibitor, approved by the FDA for the<br />

treatment <strong>of</strong> non-valvular atrial fibrillation (AF). In Europe and Canada, it has also been approved for<br />

prophylaxis <strong>of</strong> venous thromboembolism after major orthopedic surgery. Although it is considered a life<br />

saving medicine, it is associated with several significant adverse effects, including bleeding.<br />

Gastrointestinal tract bleeding is one <strong>of</strong> the most common complications reported in literature. We<br />

report a rare, spontaneous epidural hematoma secondary to Dabigatran therapy.<br />

CASE PRESENTATION: A 68-year-old Caucasian male presented to the ER with sudden onset <strong>of</strong><br />

unprovoked severe neck pain followed by progressive weakness in his legs and arms. His past medical<br />

history was significant for chronic persistent non-valvular AF. He had been taking warfarin for a nineyear<br />

period as a preventative measure for stroke. Ten days prior to admission he was switched to<br />

standard low dose Dabigatran. A CT <strong>of</strong> the spine revealed large epidural hematoma from C2 to C7. The<br />

patient was immediately taken to the OR where a successful evacuation and laminectomy was<br />

performed by a neurosurgeon. The patient experienced pr<strong>of</strong>ound improvement in his weakness over<br />

the course <strong>of</strong> his five-day hospital stay. It was decided by his Cardiologist to forgo any anticoagulation<br />

medication for three months. He was then transferred to sub acute rehab facility.<br />

DISCUSSION: Dabigatran has shown clear advantages over warfarin, but still is associated with risk <strong>of</strong><br />

major bleeds, which usually occur at higher doses. This patient experienced Dabigatran induced bleeding<br />

in a relatively rare site, while receiving a standard low dose. Our case highlights that caution should be<br />

made before switching patients, who have had stable INR on warfarin for years, to Dabigatran.<br />

pegASParginase induced hyperbilirubinemia,hypertriglyceridemia and acute pancreatitis<br />

Pavan Kumar Bhamidipati, MD Additional Authors: Suneel Vallabhaneni MD, Elias Jabbour MD,<br />

Goutham Borthakur MD<br />

INTRODUCTION: Asparaginase has been the cornerstone <strong>of</strong> chemotherapy in the management <strong>of</strong><br />

pediatric and adult ALL for almost 3 decades. Its use has been proven to add survival advantage for<br />

these patients. Its causal role in pathogenesis <strong>of</strong> hypertriglyceridemia or acute pancreatitis is poorly<br />

understood and it’s thought that hypertriglyceridemia is the inciting event for pancreatitis.Even though<br />

newer forms <strong>of</strong> Asparaginase are being used, the side effect pr<strong>of</strong>ile seems to be the same particularly<br />

with long acting pegylated form (pegASParaginase). Exact Incidence <strong>of</strong> pegASParaginase induced acute<br />

pancreatitis in adults is unknown and is estimated to be 7-10%. Here we present a case <strong>of</strong> an adult who<br />

developed hyperbilirubinemia, hypertriglyceridemia and acute pancreatitis while on treatment with<br />

pegAsparaginase for newly diagnosed ALL got successfully treated with insulin drip, antibiotic and<br />

fibrates.<br />

CASE PRESENTATION: 55 year old Caucasian male who was diagnosed with Ph+ALL 6 months ago<br />

started complaining <strong>of</strong> increased fatigue and tiredness <strong>of</strong> 1 month duration.He was seen at MD<br />

Anderson cancer center for management. His bone marrow reveled 45% lymphoid Blasts.He started<br />

treatment with hyperfractionated CVAD and Dasatinib with no response. He was started on a<br />

chemotherapy protocol containing methotrexate,vincristine,PegASParaginase and dexamethasone.<br />

PegASParaginase 5000 international units were given for 2 days per cycle. The first 3 cycles were<br />

uneventful with good response but on the 17 th day <strong>of</strong> 4 th cycle (C4D17), he had abdominal pain and<br />

nausea and presented to ED. Amylase was 896, lipase 4467, triglycerides 2321, cholesterol 243, bilirubin<br />

8.2.Lipid panel, LFTs, amylase and lipase 10days ago were normal. CT abdomen showed acute<br />

pancreatitis. He was started on regular insulin drip, Meropenem and fen<strong>of</strong>ibrate. His lipase, amylase<br />

normalized in 3days. Repeat CT-abdomen showed diminished inflammation with no pancreatic necrosis<br />

or any pseudocyst formation. He was able to tolerate diet 10 days later. But in view <strong>of</strong> this complication,<br />

he was deemed to be not a candidate for further asparaginase use. Due to interruption <strong>of</strong> therapy<br />

because <strong>of</strong> this complication his leukemia progressed.<br />

DISCUSSION: Adverse effects including hyperglycemia, hyperbilirubinemia, hypertriglyceridemia, acute<br />

pancreatitis and liver failure are more common in adult population being treated with asparaginase<br />

compounds. There are no set guidelines neither to monitor or any effective management strategies to<br />

treat these side effects. It is prudent to monitor adults that are being treated with pegASParaginase<br />

closely with high index <strong>of</strong> suspicion. A recent consensus report published discourages repeat use <strong>of</strong><br />

asparaginase in patients with this significant toxicity. Although successful management <strong>of</strong> acute<br />

pancreatitis in this setting with the use <strong>of</strong> octreotide or continuous regional arterial infusion <strong>of</strong> a<br />

protease inhibitor (Nafamostat mesylate) has been reported, further confirmation is needed.<br />

A rare and lethal cause <strong>of</strong> hematuria that lead to the diagnosis <strong>of</strong> sickle cell trait<br />

Pavan Kumar Bhamidipati, MD Shrinivas kambali MD, Suneel Vallabhaneni MD, B Babu Paidipaty MD,<br />

Steven L Jensen, MD, Bei Fang Liu, MD<br />

INTRODUCTION: Renal medullary carcinoma (RMC), the seventh sickle cell nephropathy, is a rare<br />

malignant tumor arising from collecting duct epithelium. This tumor is almost exclusive to young<br />

African-<strong>American</strong>s with sickle cell trait (SCT).These tumors have a worse prognosis and are usually<br />

metastasized at the time <strong>of</strong> diagnosis. So far, around 120 cases <strong>of</strong> RMC are reported in the literature.<br />

We present an elderly black female with multiple ED visits for persistent hematuria, initially got treated<br />

as UTI, ultimately got diagnosed with this rare condition and found to have SCT.<br />

CASE PRESENTATION: 57 y/o African-<strong>American</strong> female presented to ED with 1week history <strong>of</strong> right<br />

flank pain, increased urinary frequency and pink urine. Past history includes diabetes, hypertension and<br />

papillary carcinoma <strong>of</strong> thyroid. Urinalysis showed large blood with trace esterase, 53 RBC and 7 WBC.<br />

Renal ultrasound revealed diffuse atrophy and small cystic lesions bilaterally. She was discharged on<br />

antibiotics for UTI. She returned to the ED 2 weeks later with similar symptoms. Repeat urinalysis<br />

showed numerous RBC. Renal ultrasound showed a 5.5cm cystic structure in right mid-upper pole and<br />

CT abdomen depicted solid suprarenal mass. MAG-3 scan demonstrated a severely diminished flow to<br />

this kidney. Radical nephrectomy with lymph node dissection was done and the tumor was found to be<br />

extending into the vena cava completely occluding it both proximally and distally. RMC, pathological<br />

stage T3N1Mx was diagnosed. Near 100% association <strong>of</strong> this tumor with SCT prompted Hemoglobin<br />

electrophoresis, which revealed SCT pattern with Hemoglobin-A <strong>of</strong> 78% and Hemoglobin-S <strong>of</strong> 19%.She<br />

was discharged home in a stable condition.<br />

DISCUSSION: RMC is extremely rare tumor and it is unclear why it occurs only in SCT/SCD patients.<br />

Several genetic abnormalities have been proposed and it is thought to be from acidic and hypoxic<br />

environment <strong>of</strong> the renal medulla that promotes RBC sickling leading to this malignancy. This case<br />

underscores the importance <strong>of</strong> thorough workup through cytologic examination <strong>of</strong> urine and CT imaging<br />

in those with SCT/SCD presenting with persistent hematuria and/or flank pain. Awareness and early<br />

diagnosis <strong>of</strong> this tumor may improve survival among this cohort.<br />

Prop<strong>of</strong>ol use in a patient with neuroleptic malignant syndrome inducing hyperthermia<br />

Somy S George, MD Second Author: Swati Choudhary, MD; Narendra Khanchandani,MD; Mark<br />

Villenueve, MD<br />

INTRODUCTION:Neuroleptic malignant syndrome (NMS) is a life threatening neurologic emergency<br />

associated with the use <strong>of</strong> neuroleptic agents and characterized by a distinctive clinical syndrome <strong>of</strong><br />

mental status change, rigidity, hyperthermia and dysautonomia. Central dopamine receptor blockade in<br />

the hypothalamus may cause hyperthermia and other signs <strong>of</strong> dysautonomia. Prop<strong>of</strong>ol has been<br />

commonly used as a sedative in the intensive care unit and is generally considered safe. Case reports<br />

have shown that Prop<strong>of</strong>ol can cause hyperthermia in patients who have predisposing factors such as<br />

neuroleptic malignant syndrome.<br />

CASE PRESENTATION: Patient was a 41 year old caucasian female with past medical history significant<br />

for Diabetes Mellitus Type II, Bipolar Disorder and Hypertension was admitted with acute respiratory<br />

failure, altered mental status, and a temperature <strong>of</strong> 104. She was intubated and broad spectrum<br />

antibiotics were given for suspicion <strong>of</strong> pneumonia. Pan-culture was done which showed no bacterial<br />

growth. Her home medications included Benztropine, Chlomipramine, Clonazepam, Lamotrigine,<br />

Lithium and Ziprasidone. All her medications were stopped on the day <strong>of</strong> admission secondary to the<br />

possibility <strong>of</strong> Serotonin Syndrome versus Neuroleptic Malignant Syndrome (NMS). She was started on<br />

Prop<strong>of</strong>ol drip due to agitation and was weaned <strong>of</strong>f slowly within 3 days. Fever resolved within 2 days <strong>of</strong><br />

admission. Patient was extubated on day 4 but then was re-intubated the following day secondary to<br />

continuing respiratory failure. During second intubation, jaw clenching was noticed and one dose <strong>of</strong><br />

succinylcholine was given for rapid sequence intubation and Prop<strong>of</strong>ol was restarted. Patient’s<br />

temperature slowly started to rise with a rate <strong>of</strong> approximately 1 degree F/day to a maximum <strong>of</strong> 107 F.<br />

Prop<strong>of</strong>ol was then discontinued and patient was given Dantrolene and Bromocriptine for possibility <strong>of</strong><br />

malignant hyperthermia. Her temperature started decreasing to normothermia within 2 days after<br />

discontinuation <strong>of</strong> Prop<strong>of</strong>ol. During the time <strong>of</strong> her hospital stay, the patient developed multi-organ<br />

failure. Due to patient’s poor prognosis the family made her hospice and she passed 19 days after<br />

admission. Multiple factors were responsible for hyperthermia, including NMS, use <strong>of</strong> succinylcholine,<br />

and prop<strong>of</strong>ol. But due to the duration <strong>of</strong> onset <strong>of</strong> hyperthermia, prop<strong>of</strong>ol was the most likely culprit.<br />

DISCUSSION: Prop<strong>of</strong>ol should be used cautiously in patients who have mulitple risk factors to<br />

hyperthermia. Alternative sedative agents should be used. Further studies need to be done to<br />

understand the exact mechanism <strong>of</strong> hyperthermia caused by prop<strong>of</strong>ol in these high risk patients.<br />

Bicalutamide induced hepatotoxicity; a rare adverse effect<br />

Salwa Hussain, MBBS, Jeffrey Najor, Ahmer Ali, MD<br />

INTRODUCTION: There are extremely small number <strong>of</strong> cases reported in literature that highlight the<br />

hepatotoxic potential <strong>of</strong> bicalutamide, a nonsteroidal antiandrogen used extensively during the start <strong>of</strong><br />

androgen deprivation therapy with a luteinizing hormone-releasing hormone agonist to reduce<br />

occurrence <strong>of</strong> the symptoms <strong>of</strong> tumor flare in patients with metastatic prostate carcinoma. The most<br />

common adverse effects <strong>of</strong> bicalutamide are induced by its pharmacologic property <strong>of</strong> competitive<br />

androgen receptor blockade and include gynecomastia, hot flashes, fatigue, and decreased libido.<br />

Although not as common, increases in liver function test results are also seen with bicalutamide therapy.<br />

These elevations are typically transient, and patients remain asymptomatic. We share our experience <strong>of</strong><br />

a case <strong>of</strong> symptomatic acute hepatoxicity secondary to the use <strong>of</strong> Bicalutamide and employ this<br />

opportunity to present a brief review <strong>of</strong> existing literature.<br />

CASE PRESENTATION: We report the case <strong>of</strong> an 81 year-old African <strong>American</strong> male with a metastatic<br />

prostate cancer who presented with nonspecific symptoms <strong>of</strong> decreased appetite, lack <strong>of</strong> energy,<br />

generalized weakness and feeling <strong>of</strong>f balance for three days and jaundice for one day. He also reported<br />

dark colored urine for one week. He was started on a trial <strong>of</strong> Bicalutamide 3 weeks prior to presentation.<br />

On physical exam, scleral icterus was noted. Workup revealed acutely elevated liver enzymes(more than<br />

5 times the upper limit <strong>of</strong> normal) , alkaline phosphatase, conjugated hyperbilirubinemia and<br />

coagulopathy. US abdomen was negative for obstruction. Other etiologies including viral, common<br />

toxins and drugs, autoimmune and ceruloplasmin induced insult were ruled out. Bicalutamide was held<br />

and patient managed with supportive care. He showed clinical improvement and normalization <strong>of</strong> the<br />

above labs within days.<br />

DISCUSSION: This case highlights the hepatotoxic potential <strong>of</strong> Bicalutamide. The largest study to date<br />

addressing steroidal and non steroidal antiandrogen induced hepatoxicity was conducted in Spain in<br />

2005, employing the Spanish pharmacovigilance database. It, however, remained inconclusive for<br />

Bicalutamide induced hepatotoxicity due to the scarcity <strong>of</strong> reported cases by physicians, pharmacists<br />

and nurses. Our case reviews literature on the topic and is a valuable addition to this life threatening<br />

adverse effect <strong>of</strong> Bicalutamide<br />

An Atypical Presentation Of Pancreatic Cancer<br />

Salwa Hussain, MBBS, Jaspreet Kaur Ghumman, DO. Dept. <strong>of</strong> Internal Medicine and Dept. <strong>of</strong><br />

Gastroenterology, Providence Hospital, Southfield, MI<br />

INTRODUCTION:Pancreatic carcinoma is a debilitating disease and carries a poor prognosis. The<br />

incidence <strong>of</strong> pancreatic adenocarcinoma directly invading the gastrointestinal tract leading to<br />

gastrointestinal hemorrhage is very low. Here, we describe one unique case manifesting<br />

characteristically severe and unremitting hamatochezia as an initial presentation <strong>of</strong> pancreatic<br />

adenocarcinoma.<br />

CASE PRESENTATION: A 75 year old African <strong>American</strong> man presented initially with hematochezia for 1<br />

week with no other alarm symptoms. Physical exam was negative except for melanotic stool and<br />

absence <strong>of</strong> bright red blood on rectal exam. Initial labs in the <strong>of</strong>fice showed normocytic anemia.<br />

Scheduled colonoscopy revealed left sided diverticulosis and some melanotic stool with blood seen<br />

throughout the colon. Emergent EGD was performed revealing an ulcerated mass in the third part <strong>of</strong><br />

duodenum covered by an overlying adherent clot with no active bleeding. A decision was made not to<br />

dislodge the clot and patient was admitted for further investigation. Subsequent CT <strong>of</strong> the abdomen and<br />

pelvis revealed multiple liver lesions and a nonspecific, 4cm cystic mass in the abdominal midline. A liver<br />

biopsy followed but was inconclusive. Repeat EGD was performed to obtain biopsy which reported a<br />

well differentiated adenocarcinoma and benign duodenal mucosa. Endoscopic ultrasound for further<br />

evaluation, thereafter, revealed a pancreatic head mass with invasion in to the duodenal wall, as well as<br />

vascular involvement.<br />

DISCUSSION: There are a few cases reported in literature where major digestive hemorrhage was the<br />

first sign <strong>of</strong> a subsequently proven pancreatic malignancy. The most characteristic sign <strong>of</strong> pancreatic<br />

carcinoma <strong>of</strong> the head <strong>of</strong> pancreas is painless obstructive jaundice. Clinicians should be aware that<br />

pancreatic malignancy may present with a varying spectrum <strong>of</strong> GI bleeding ranging from occult to<br />

potentially exsanguinating hematemesis, hematochezia, or melena.<br />

An Interesting Case <strong>of</strong> Catamenial Hemopneumothorax<br />

Mayuri Sunil Jagirdar, MD Huda Elhwairis MD Basim Towfiq MD<br />

INTRODUCTION:<br />

Thoracic endometriosis is a rare disorder with presence <strong>of</strong> endometrial tissues within the pleura, lung<br />

parenchyma and airways. Clinical presentation includes spontaneous pneumothorax and hemothorax<br />

occurring in relation to menses which is referred to as Catamenial.<br />

CASE PRESENTATION: A 26Y/AA/waitress with no PMH, non smoker, presented with complaints <strong>of</strong><br />

progressive shortness <strong>of</strong> breath for one month. She complained <strong>of</strong> decreased appetite, weight loss <strong>of</strong><br />

about 8lbs over 1 month and abdominal cramps due to menstrual cycle. Examination showed a thin<br />

appearing female with BMI <strong>of</strong> 17 and no significant findings except tachypnea. Pleural effusion was<br />

noted clinically which was confirmed with chest radiograph. Labs were unremarkable except for mild<br />

anemia and mildly elevated CA-125. Pleural fluid on aspiration was grossly bloody with RBCs but<br />

negative for lymphocytes and malignant cells. Approximately 3000cc was drained in 24 hours. A chest<br />

tube was placed and output was less than 150cc in 24hrs. Follow up chest x-ray showed development <strong>of</strong><br />

Tension Pneumothorax. She underwent Video Assisted Thoracoscopy and Mini thoracotomy which<br />

showed air leaks in right middle lobe which was resected. She underwent Abdominal Laparoscopy to<br />

find the cause for ascites and right Thoracotomy as she had continued air leaks post-operatively. The<br />

abdominal laparoscopy showed hemoperitoneum with small chocolate cysts along the rectovaginal<br />

septum with extensive adhesions. The posterior aspect <strong>of</strong> the uterus showed a ruptured chocolate cyst<br />

with fresh bleeding and clots. Right thoracotomy revealed multiple fenestrations in the diaphragm and<br />

presence <strong>of</strong> endometrial implant which were the source <strong>of</strong> air leaks along with a large bulla. The<br />

fenestrations were sealed and the bulla was resected and a chest tube was placed. She improved<br />

clinically with no air leaks from the chest tube. She was given a Lupron injection for suppression <strong>of</strong> the<br />

Hypophyseal gonadal axis and to follow up on outpatient basis. She has shown no signs <strong>of</strong> recurrence for<br />

5 months since discharge.<br />

DISCUSSION: This case illustrates the clinical presentation <strong>of</strong> Catamenial hemopneumothorax. Most <strong>of</strong><br />

the cases reported were young reproductive African <strong>American</strong> females with involvement <strong>of</strong> the right<br />

side <strong>of</strong> the chest. Along with clinical suspicion, diagnosis is confirmed with Video Assisted Thoracic<br />

Surgery. Treatment consists <strong>of</strong> GnRh analogues to suppress the HPA axis and surgical management,<br />

although 50% recurrence rate is reported.<br />

A Case <strong>of</strong> Death Due to Ibogaine Use for Heroin Addiction<br />

Shwan Mohamod Dhahir Jalal, MD, MBChB, Edouard Daher MD, FACP, Raymond Hilu MD, FACP<br />

INTRODUCTION: Ibogaine is a natural psychoactive substance that is found in a number <strong>of</strong> plants<br />

known as Iboga in Africa. It is widely used in Gabonian initiation ceremonies which is known to cause<br />

near-death experiences. Ibogaine has been used to treat opioid and cocaine addiction because <strong>of</strong> its<br />

effectiveness in reducing withdrawal symptoms, and decreasing craving. However, in the United States<br />

and most European countries, Ibogaine use is prohibited due to reported deaths. Ibogaine has a<br />

complex mechanism <strong>of</strong> action through different neurotransmitters. Which includes NMDA receptor<br />

antagonists, the serotonin transporter, and putative agonists on Kappa- and Mu-opioid receptors.<br />

Ibogaine a can also decrease ethanol consumption through Increased glial cell line-derived neurotrophic<br />

factor (GDNF) in the ventral tegmental area. Ibogaine can cause sudden death by cardiac and non-<br />

cardiac means. It can cause QT interval prolongation, and induce heart failure secondary to autonomic<br />

imbalance caused by sympathetic over activity from the left cerebral hemisphere. Non cardiac causes<br />

include respiratory failure.<br />

CASE PRESENTATION: Our patient is a 25 year old gentleman with past medical history <strong>of</strong> SVT treated<br />

with RF ablation, and pacemaker placement at age <strong>of</strong> 11. He was a heroin addict with a long history <strong>of</strong><br />

unsuccessful attempts <strong>of</strong> detoxification including methadone. He decided to try Ibogaine. After taking<br />

2.5 grams <strong>of</strong> Ibogaine over 3 hours, the patient started to have hallucinations, ataxia, muscle spasms,<br />

weakness, fever, and urinary retention. Later that day most <strong>of</strong> those symptoms resolved except for<br />

muscle spasms and ataxia. He developed respiratory difficulty overnight followed by cardiopulmonary<br />

arrest the following morning. The patient was successfully resuscitated on the field and was brought to<br />

the hospital, and then transferred to the ICU. On physical exam the patient was in a decorticate position,<br />

had muffled heart sounds, and coarse breath sounds bilaterally. Initial labs showed WBC24.5, Hgb13.8,<br />

BUN36, Cr.2.61,AST 1099,ALT 491,Troponin2.39,and CPK 10,535. A CT <strong>of</strong> the brain revealed cerebral<br />

edema. Echocardiogram showed EF 10% with severe global hypokinesis. The patient expired after 2 days<br />

from multiorgan failure.<br />

DISCUSSION: There is evidence from animal studies to suggest that Ibogaine can reduce withdrawal<br />

symptoms and craving <strong>of</strong> addiction . However, there have been no rigorous scientific clinical trials<br />

conducted in humans. With the increase in the number <strong>of</strong> ibogaine users around the world, it is<br />

necessary for more research in humans to help elucidate more information regarding the efficacy and<br />

safety <strong>of</strong> Ibogaine. We present this case to bring awareness to health pr<strong>of</strong>essionals <strong>of</strong> the use <strong>of</strong><br />

ibogaine by addicts and its dangers and toxicity.<br />

Cannabinoid hyperemesis: Cyclical vomiting and Compulsive Bathing<br />

Joe Marie Jose-Dizon, Parul Sud, Siva Talluri, Siddesh Besur<br />

INTRODUCTION: Cannabis is one <strong>of</strong> the most commonly abused recreational drugs in the United<br />

States, and now is being widely approved for medicinal purposes. Chronic use is associated with<br />

pulmonary, reproductive and psychosocial disorders. We report a rare case <strong>of</strong> cannabinoid hyperemesis<br />

syndrome and its economic impact.<br />

CASE PRESENTATION: A 41-year-old Caucasian female presented to the emergency room with a fiveday<br />

history <strong>of</strong> vomiting recurring every fifteen minutes. The vomitus was non-bloody, non-bilious and<br />

was associated with epigastric pain. Symptoms were relieved by hot baths, and she reported up to fifty<br />

per day. Past medical history included hypertension, myocardial infarction and cholecystectomy.<br />

Personal history was remarkable for daily cannabis use for twenty years. On physical examination, vital<br />

signs were normal. The abdomen was s<strong>of</strong>t with epigastric tenderness and normal bowel sounds. Workup<br />

including complete blood count, renal and liver function tests, serum amylase and lipase were<br />

normal. Her urine pregnancy test was negative and urine toxicology was positive for<br />

tetrahydrocannabinol. The computerized tomography scan <strong>of</strong> the abdomen, upper gastrointestinal<br />

endoscopy, and colonoscopy were normal. Intravenous fluids and antiemetics resulted in symptom<br />

resolution. We made a diagnosis <strong>of</strong> cannabinoid hyperemesis syndrome based on her chronic cannabis<br />

use, persistent vomiting and compulsive bathing. She was counseled and referred to a substance abuse<br />

program. Unfortunately she continued to use cannabis with recurrent episodes resulting in multiple<br />

hospital admissions over the next five months. When seen in the clinic on follow up after six months,<br />

she had been <strong>of</strong>f marijuana for one month and had been asymptomatic. Total cost to date for this<br />

patient’s multiple ER visits and admissions is $80,000.<br />

DISCUSSION: Cannabinoid hyperemesis syndrome is known to occur in chronic marijuana users. It is<br />

associated with recurrent nausea, vomiting and abdominal pain and is alleviated by hot baths. The fat<br />

solubility <strong>of</strong> cannabis prolongs its half life and leads to chronic stimulation <strong>of</strong> CB1 receptors. The<br />

recurrent vomiting is proposed to occur when CB1 receptors in the gut override CNS receptors and<br />

suppress peristalsis and gastric emptying. The relief associated with warm bathing is thought to be due<br />

to stimulation <strong>of</strong> CB1 receptors in cutaneous vessels, causing a cutaneous steal syndrome. There is a<br />

temporal relationship between cannabis use and the onset and resolution <strong>of</strong> symptoms.<br />

Cannabinoid hyperemesis syndrome should be considered in patients presenting with abdominal pain<br />

and recurrent vomiting in the setting <strong>of</strong> chronic marijuana use.<br />

Is it possible? Clozapine Induced Hemorrhagic Pericardial Effusion Causing Cardiac Tamponade<br />

Zaid Kasmikha, DO, Timothy Larsen, DO, Zaid Yaldo, MD, Sachin Amruthlal-Jain, MD, Jamal Zarghami,<br />

MD, Shukri David, MD<br />

INTRODUCTION:Clozapine is an atypical antipsychotic frequently used in the treatment <strong>of</strong><br />

schizophrenia, <strong>of</strong>ten in patients who have failed other therapies. Tachycardia and orthostatic<br />

hypotension are well-recognized cardiovascular adverse effects <strong>of</strong> the drug, occurring in up to 25% and<br />

9% <strong>of</strong> patients, respectively. There is increased concern about the more serious cardiac adverse<br />

reactions in patients taking Clozapine, such as pericarditis, myocarditis and cardiomyopathy. Herein, we<br />

report a rare case <strong>of</strong> Clozapine induced hemorrhagic pericardial effusion.<br />

CASE PRESENTATION: A 58 year old African <strong>American</strong> male with a longstanding history <strong>of</strong><br />

schizophrenia controlled with Clozapine 750 mg daily for about one year, presented to the emergency<br />

room with complaints <strong>of</strong> chest discomfort, fatigue, tachycardia and progressive shortness <strong>of</strong> breath.<br />

Symptoms were non-remitting resulting in acute respiratory failure requiring intubation and ICU<br />

management. A 12-lead EKG revealed low QRS voltage with electrical alternans. Echocardiogram<br />

identified a large pericardial effusion with tamponade physiology. Pericardiocentesis performed at<br />

bedside removed 350 mL <strong>of</strong> hemorrhagic fluid. Pericardial fluid analysis revealed a high red cell count<br />

with a normal white cell count, while gram stain, bacterial culture, AFB stain and culture were all<br />

negative. Extensive serologic studies including rheumatioid factor, ANA, sedimentation rate, fibrinogen<br />

levels, ribonucleoprotein-peptide, TSH, C3, C4, HIV serology, anti-smith antibody, anti-double stranded<br />

DNA antibodies, and Cocksackie A/B antibodies were performed. Of these, only rheumatoid factor, ANA<br />

and sedimentation rate were remarkable. Approximately 1300 mL <strong>of</strong> hemorrhagic pericardial fluid was<br />

drained over 5 days. With an essentially negative workup, Clozapine was suspected as a potential<br />

etiology. After its discontinuation, the patient’s symptoms improved and the pericardial drainage<br />

ceased. Repeat echocardiogram showed no recurrence <strong>of</strong> the pericardial effusion.<br />

DISCUSSION: Although cases <strong>of</strong> Clozapine induced pericardial effusion are rare, it has been reported in<br />

the literature. Our case demonstrates that the hemorrhagic pericardial effusion was iatrogenic for the<br />

following reasons. First, other etiologic factors that could have caused pericardial effusion were<br />

excluded. Second, our patient lacked cardiovascular risk factors and symptomatic pericarditis in an<br />

otherwise healthy, young individual is uncommon. Third, the effusion resolved after discontinuation <strong>of</strong><br />

the <strong>of</strong>fending agent, Clozapine. The Naranjo Probability Scale identified our patient’s pericardial effusion<br />

as a probable adverse drug reaction secondary to Clozapine. An appropriate medical history and physical<br />

examination is warranted prior to initiating Clozapine. Early recognition and intervention is vital to<br />

prevent serious cardiac adverse reactions.<br />

An Unusual Emerging Complication Of H1N1 Influenza Disease<br />

Eve E Kenfack MD, Jean Fotso MD, Abhilasha Pandey MD, Vijayalakshmi Nagappan MD, Ghadi Ghorayeb<br />

MD.<br />

INTRODUCTION: Mediastinitis is a life-threatening emergency. In the Unites States, most cases are<br />

related to cardiovascular surgery with Staplylococcus aureus as pathogen. In patients who have not<br />

undergone surgery, the two most common causes are esophageal rupture and descending<br />

mediastinitis with Streptococcus and anaerobes leading the list <strong>of</strong> causative agents. We report the first<br />

case <strong>of</strong> methicillin-resistant Staphylococcus aureus acute mediastinitis after H1N1 influenza infection.<br />

CASE PRESENTATION: A 60 years old female with history <strong>of</strong> asthma, coronary disease and diabetes<br />

presented to our emergency room with right sided chest pain and worsening dyspnea. This was her third<br />

presentation to the emergency room for the past 10 days. Her initial symptoms were dyspnea,<br />

wheezing, dry cough and subjective fevers and chills for which she was treated for asthma exacerbation.<br />

The nasopharyngeal rapid antigen test returned positive for influenza A. She was started on oseltamivir<br />

and was discharged after 5 days. Her symptoms waxed 2 days later and she went to another<br />

hospital. Her chest X rays had remained unremarkable. She was discharged 48h later after another<br />

course <strong>of</strong> bronchodilators and steroids with antibiotics. She returned to our facility 24h later. Her<br />

shortness <strong>of</strong> breath had worsened, she had developed right sided chest pain extending to the neck. On<br />

examination, there was excruciating tenderness on the right side <strong>of</strong> the chest. No crepitus, no swelling.<br />

Normal oral and skin exam. White count was 26.9.The repeated chest X ray showed a widened<br />

mediastinum and haziness at right lung base. A CT scan <strong>of</strong> the chest revealed complex right-sided<br />

effusion, large opacity in the right paratracheal area and diffuse haziness in the posterior mediastinum<br />

suspicious for mediastinitis. Esophagogram: no evidence <strong>of</strong> esophageal perforation. CT-neck: no abscess.<br />

CT-thoracentesis: purulent effusion. A cardiothoracic surgeon was consulted. Intraoperative findings<br />

were consistent with purulent mediastinitis. The patient underwent an urgent right thoracotomy with<br />

debridement <strong>of</strong> mediastinal abscess, mediastinal lymphadenectomy, and decortication <strong>of</strong> the left lung.<br />

Broad spectrum antibiotics were started. Cultures <strong>of</strong> the mediastinal abscess, the pleural fluid as well as<br />

blood and sputum grew methicillin resistant Staphylococcus aureus. She was continued on vancomycin.<br />

Influenza A PCR <strong>of</strong> nasopharyngeal aspirate: positive for H1N1. She was continued on oseltamivir. Her<br />

symptoms improved. On day 15, she was discharged to a long term acute care facility.<br />

DISCUSSION: The most common complication <strong>of</strong> H1N1 influenza is fulminant pneumonia. Benign<br />

pneumomediastinum and subcutaneous emphysema have been described in children. After infection<br />

with H1N1 flu, our patient developed a staphylococcal superinfection causing severe mediastinitis and<br />

a right empyema. A smaller proportion <strong>of</strong> acute mediastinitis is caused by the extension <strong>of</strong> pneumonia,<br />

lung abscesses and pleural empyema. We believe that the severe mediastinitis was secondary to an<br />

extension <strong>of</strong> the right empyema into the mediastinum.<br />

In summary, we present the second case in the literature <strong>of</strong> acute mediastinitis in the subset <strong>of</strong> H1N1<br />

influenza disease. <strong>Physicians</strong> should be aware <strong>of</strong> mediastinitis as a potentially severe complication <strong>of</strong><br />

H1N1 influenza as early recognition is a key factor to survival.<br />

Thyrotoxic Periodic Paralysis in a young African- <strong>American</strong> patient- A case report<br />

Tejaswini Kulkami, MD MPH; Manisha Srinivasa MBBS; Samantha Staley MD; Kamalakar Nerusu MD<br />

INTRODUCTION: Hypokalemic periodic paralysis is a rare and potentially lethal complication <strong>of</strong><br />

hyperthyroidism characterized by proximal muscle paralysis and hypokalemia with biochemical evidence<br />

<strong>of</strong> thyrotoxicosis. Many affected patients may not have obvious symptoms and signs <strong>of</strong> hyperthyroidism.<br />

These patients will spontaneously recover muscle strength without treatment but potassium<br />

supplementation will prevent cardiac arrhythmias and hasten recovery during the acute phase.<br />

Thyrotoxic Periodic Paralysis (TPP) is a disease <strong>of</strong> young Asian males and the incidence in North America<br />

was reported to be only around 0.1% in thyrotoxic patients. However, with increasing population<br />

mobility and admixture, TPP as the presenting feature <strong>of</strong> hyperthyroidism has increased in Western<br />

countries.<br />

CASE PRESENTATION: A 24-year-old African <strong>American</strong> male with no past medical history presented<br />

with sudden onset weakness in his thighs and arms which progressed to an inability to move his<br />

extremities. The patient reported experiencing at least six such transient, self-resolving episodes in the<br />

past one year. He did visit his primary care physician but no diagnosis was made. On a review <strong>of</strong><br />

symptoms, he stated that he had episodes <strong>of</strong> palpitations and tremulousness, was intolerant to high<br />

temperatures and had lost weight. He denied any skin or hair changes and changes in his bowel<br />

movements. He was not on any home medications. He had a family history <strong>of</strong> Grave’s disease in that<br />

both his maternal and paternal grandmothers, both his parents and two siblings were affected.<br />

However, none <strong>of</strong> these members had a history <strong>of</strong> paralysis. On exam, he was tachycardic with a heart<br />

rate <strong>of</strong> 104; his thyroid was diffusely enlarged; he had no exophthalmoses or tremors. His weakness had<br />

improved considerably at this time and motor test showed mild to moderate weakness in bilateral<br />

proximal arm and thigh. Initial laboratory tests revealed potassium <strong>of</strong> 2.6, magnesium <strong>of</strong> 1.4 and<br />

creatinine phosphokinase level <strong>of</strong> 1127 with normal urine potassium. TSH was found to be less than<br />

0.002 (0.5-6µIU/L), T3 was 551(1.71-3.71pg/dl) and T4 was 22.5(0.7 -1.48 ng/dl). EKG showed sinus<br />

tachycardia. Ultrasound <strong>of</strong> the thyroid showed mildly enlarged gland with increased vascularity but no<br />

nodularity. A diagnosis <strong>of</strong> hypokalemic paralysis due to thyrotoxicosis was made. Potassium was<br />

adequately replaced and monitored. He was started on propylthiouracil 100 mg every 8 hours. His<br />

symptoms resolved and he was discharged home with a follow- up appointment for further<br />

management.<br />

DISCUSSION: This condition is rare in African- <strong>American</strong>s and can be frequently overlooked and<br />

misdiagnosed on presentation. A high degree <strong>of</strong> physician awareness is required to recognize the<br />

association with thyroid disease especially when patients present with unexplained hypokalemia,<br />

muscular weakness and rhabdomyolysis.<br />

An unusual complication <strong>of</strong> weight lifting: Aortic Dissection!<br />

Navneet Kumar, MD Other Authors: Navneet Kumar, MD, Asad Omar, MD, Samira Ahsan, MD<br />

INTRODUCTION:Aortic dissection (AD) is a catastrophic event secondary to number <strong>of</strong> known<br />

precipitating factors (Kamalakannan, 2007). Weight lifting, on the contrary is a rare causes <strong>of</strong> AD.<br />

Researchers from Yale University School <strong>of</strong> Medicine reported 31 patients having AD precipitated by<br />

weight lifting, <strong>of</strong> which 4 had Sanford Type B. Extensive literature search showed most articles describe<br />

Sanford Type A AD and with existing aortic dilation presenting with acute onset chest pain after weight<br />

lifting. We report a rare case <strong>of</strong> non-Marfan elderly patient with localized intimal dissection in non<br />

dilated infrarenal abdominal aorta (Sanford Type B/ DeBakey's Type IIIb) presenting as sudden onset<br />

abdominal pain after weight lifting.<br />

CASE PRESENTATION: 60- year old African-<strong>American</strong> gentleman presented with a 3-day history <strong>of</strong><br />

acute onset left lower quadrant abdominal pain which started while moving his friend’s heavy furniture.<br />

Clinical examination revealed mild left lower quadrant abdominal tenderness on deep palpation with<br />

otherwise normal exam. Vitals and routine labs were within normal limits. EKG showed sinus. Contrastenhanced<br />

CT scan <strong>of</strong> abdomen/pelvis revealed localized infrarenal abdominal aorta intimal dissection<br />

from origin <strong>of</strong> inferior mesenteric artery, extending approximately 3cm caudally. No retroperitoneal<br />

hemorrhage. Aortic diameters were 1.8x1.9cm in transverse and AP planes respectively. No CT/clinical<br />

evidence <strong>of</strong> bowel ischemia were apparent. No history/clinical evidence <strong>of</strong> Marfan's syndrome/ Ehlers-<br />

Danlos' syndrome/syphilis/vascular anomaly/trauma were noted. Conservative management was<br />

started. Beta blocker was given to maintain heart rate

Spontaneous visceral artery dissection<br />

Leonardo E Lopez, Jr MD Second Author: Mohammed Ibrahim MD<br />

INTRODUCTION: Spontaneous visceral artery dissection is a rare event, especially in the digestive<br />

arteries. Even rarer is the occurrence <strong>of</strong> a true spontaneous celiac artery dissection. Potential<br />

complications include ischemia <strong>of</strong> the organs supplied, aneurysm formation, arterial rupture and<br />

bleeding. We report a case <strong>of</strong> an acute splenic infarction secondary to a spontaneous dissection <strong>of</strong> the<br />

celiac artery.<br />

CASE PRESENTATION: A 44-year-old male non-smoker presented to our emergency center for suddenonset<br />

left upper quadrant abdominal pain, non-radiating, which was described as sharp and<br />

stabbing. He denied any other associated symptoms. His past medical history was negative for<br />

coagulopathy , hemoglobinopathy, hyperlipidemia, hypertension, heart disease or intravenous drug<br />

use. He denied any significant trauma to the abdomen. On admission, tests for hepatic and pancreatic<br />

etiologies were negative. A computed tomography (CT) scan <strong>of</strong> the abdomen showed an acute splenic<br />

infarction. Hypercoagulability testing and sickle cell screen were negative. An initial abdominal duplex<br />

scan did not reveal any vascular compromise to the spleen, but an abdominal CT angiography showed an<br />

arterial dissection originating in the celiac artery, extending into the common hepatic and splenic<br />

arteries, causing splenic perfusion compromise. Inflammatory causes <strong>of</strong> dissection were ruled out.<br />

During the admission, he had hypertensive episodes. He was managed conservatively with<br />

anticoagulation using heparin drip then warfarin (target INR 2-3), and tight blood pressure control. At<br />

his sixth month follow up, he was asymptomatic and doing well. Repeat CT angiography <strong>of</strong> the<br />

abdomen redemonstrated a proximal celiac artery dissection.<br />

DISCUSSION: Spontaneous celiac artery dissection as a differential diagnosis for acute abdominal pain<br />

with splenic infarction can be missed due to its rarity. There are only less than 30 reported cases in the<br />

literature. The patients are predominantly middle-aged men. The cause is still unknown. Risk factors<br />

include atherosclerotic disease, hypertension, fibromuscular dysplasia, trauma and connective tissue<br />

disease. Epigastric pain is a cardinal symptom, but the lesion may be asymptomatic. Uncomplicated<br />

cases are usually successfully managed medically with close monitoring.<br />

Modern Milk Alkali Syndrome: A Case Report<br />

Ridhwi Mukerji, MD Siva Talluri, MD Siddesh Besur, MD<br />

INTRODUCTION: Hypercalcemia is a common clinical problem. We discuss a modern variant <strong>of</strong> milk<br />

alkali syndrome (MAS) secondary to calcium carbonate ingestion.<br />

CASE PRESENTATION: A 69 year-old female presented with progressive weakness, intractable nausea<br />

and vomiting. Past medical history was significant for hypertension, GERD and hiatal hernia. Medications<br />

included lisinopril, hydrochlorothiazide and over-the-counter (OTC) Tums®. Examination showed only<br />

signs <strong>of</strong> dehydration. Laboratory revealed acute renal failure, metabolic alkalosisis, hypokalemia and<br />

hypercalemia. Malignancy was ruled out after a work-up that included CT scan <strong>of</strong> head, chest, and<br />

abdomen. Patient’s vitamin D and serum phosphorus levels were low. Intact parathormone,<br />

parathormone-related peptide and serum and urine protein electrophoresis were normal. Patient was<br />

hydrated and received one dose <strong>of</strong> pamidronate 90 mg resulting in hypocalcemia requiring treatment.<br />

After a hospital stay <strong>of</strong> twelve days, the patient was discharged with normal biochemical<br />

parameters. Without other identifiable causes and with the patient’s history <strong>of</strong> OTC Tums® usage,<br />

along with the typical clinical presentation, the patient was diagnosed to have MAS.<br />

DISCUSSION: Over the last couple <strong>of</strong> decades, the incidence <strong>of</strong> MAS as a cause <strong>of</strong> hypercalcemia has<br />

been found to be as high as 12%.The classic triad consists <strong>of</strong> hypercalcemia, metabolic alkalosis, and<br />

renal insufficiency secondary to ingestion <strong>of</strong> large amounts <strong>of</strong> absorbable alkali and calcium. Daily<br />

elemental calcium intake <strong>of</strong> two grams or less is considered safe, however lower doses have been<br />

shown to cause MAS due to predisposing factors like abnormal kidney function, inability <strong>of</strong> the skeletal<br />

system to buffer calcium, individual variations in buffering capacity, thiazide diuretic use or excessive<br />

vomiting. The hypercalcemia and metabolic alkalosis result in a positive feedback loop producing the<br />

clinical picture <strong>of</strong> MAS. The low to normal phosphorus values in modern MAS are due to calcium<br />

carbonate, acting as a phosphorus binder. Treatment is hydration, withdrawal <strong>of</strong> the <strong>of</strong>fending agent<br />

and diuretic therapy. However, in severe cases, bisphosphonates may be used with caution to avoid<br />

hypocalcemia. Also, bisphosphonate therapy can be counterproductive since bone resorption is not<br />

thought to be a contributing mechanism.<br />

Renal function usually requires only supportive measures. Renal failure in MAS is thought to be<br />

mediated by tubular epithelium degeneration and granular (presumably calcium-laden) materials inside<br />

and around collecting tubules along with hyalinization <strong>of</strong> glomeruli and thickening <strong>of</strong> the basement<br />

membrane.<br />

Conclusion: The increasing incidence <strong>of</strong> MAS has been hypothesized to be a result <strong>of</strong> OTC availability <strong>of</strong><br />

calcium carbonate. Due to the innocuous nature <strong>of</strong> these supplements the general public is unaware <strong>of</strong><br />

its potential complications. History is <strong>of</strong>ten not forthcoming because <strong>of</strong> their OTC status. But, due to the<br />

reversible nature <strong>of</strong> this problem, physicians and lay persons should be aware <strong>of</strong> this condition.<br />

Malignant Cerebral Edema Following CT Lumbar Myelogram Using Omnipaque-300 (Iohexol) Non-Ionic<br />

Water Soluble Contrast Dye<br />

Ridhwi Mukerji, MD Aileen M. Arguelles, MD Shaun A. Wahab, MD Radhika Kakarala, MD<br />

INTRODUCTION:Intrathecal injection <strong>of</strong> ionic contrast dyes have been reported to result in serious<br />

neurological adverse effects. But to our knowledge, there is only one documented case report <strong>of</strong><br />

malignant cerebral edema in response to lumbar myelography using non-ionic water soluble contrast<br />

dye. We report a second case with symptomatic and radiographic evidence <strong>of</strong> severe cerebral edema<br />

following use <strong>of</strong> Omnipaque-300® (iohexol), a non-ionic contrast dye.<br />

CASE PRESENTATION: A 74 year old Caucasian male was admitted to our hospital with significant<br />

generalized weakness and chronic back pain for which he underwent a CT lumbar myelogram. Soon<br />

after, the patient displayed increasing generalized weakness, altered mental status and slurred speech.<br />

The exam revealed stable vital signs, papilledema, decreased reflexes and power without localizing<br />

signs. A stat CT scan <strong>of</strong> the head showed findings consistent with diffuse cerebral edema without<br />

midline shift. Past medical history was significant for hypertension, dyslipidemia, COPD, diabetes, CHF,<br />

CAD and morbid obesity. Medication review ruled out side effects as a contributory cause. Review <strong>of</strong><br />

systems was negative. The patient was admitted to the ICU with elevation <strong>of</strong> the head <strong>of</strong> the bed and<br />

started on dexamethasone and mannitol. Leviracetam was administered for seizure prophylaxis.<br />

Neurosurgery consult concurred with our management. The patient’s condition improved the next day<br />

and was asymptomatic soon thereafter. A repeat CT scan showed near complete resolution <strong>of</strong> his<br />

cerebral edema. In the absence <strong>of</strong> other possible causes and the temporal correlation with the adverse<br />

event, the contrast media used for the CT-myelogram was the most likely cause for the patient’s<br />

cerebral edema.<br />

DISCUSSION: Cerebral edema is visible radiographically as sulcal effacement and obliteration <strong>of</strong> basal<br />

cisterns. Its consequences can be life threatening and it needs to be immediately identified. Based<br />

upon our review <strong>of</strong> the literature, we identified several potential mechanisms for the cerebral edema as<br />

follows: blood-brain-barrier dysfunction, indirect neuronal post-membrane action, changes in the<br />

extracellular milieu <strong>of</strong> neurons and loss <strong>of</strong> cerebral vascular autoregulation with resulting vasogenic<br />

edema. Our therapy was directed at the latter. The osmotherapy with mannitol allowed water<br />

movement from the cerebral extracellular compartment into the vasculature. Steroids helped stabilize<br />

the disrupted blood-brain-barrier. The head <strong>of</strong> bed elevation facilitated a decrease in the cerebrospinal<br />

fluid hydrostatic pressure whereas avoidance <strong>of</strong> mechanical jugular venous compression decreased<br />

venous outflow impedance from the cranium.<br />

Conclusion<br />

It is crucial for physicians to be cognizant <strong>of</strong> this rare complication, to avoid missed or delayed diagnosis<br />

and treatment <strong>of</strong> this potentially lethal problem. Hence the reaction must be documented in the<br />

patient’s medical record with subsequent avoidance <strong>of</strong> non-ionic contrast dyes like iohexol or pre-treat<br />

the patient with steroids.<br />

Tewari<br />

INTRODUCTION: Septic shock is one <strong>of</strong> the most common presentations <strong>of</strong> hypotension in the ICU.<br />

However if the patient is not improving with appropriate management, other causes should be sought.<br />

CASE PRESENTATION: A 62-year-old man with a history <strong>of</strong> hypertension and diabetes mellitus<br />

presented with headache, fatigue and dizziness. He was treated with amoxicillin for suspected otitis<br />

media for two days prior to admission. However, his condition deteriorated rapidly and he was brought<br />

to the ER, where he was found to be febrile, hypotensive and in acute renal failure. His WBC was 4,600<br />

with 17% bands and platelet count was 82,000. Transaminases were also elevated, while CSF analysis<br />

was within the normal range. HSV PCR was negative. He was admitted to the ICU with an impression <strong>of</strong><br />

septic shock and he was resuscitated with IV fluids, followed by pressors to maintain blood pressure.<br />

Vancomycin and Cefepime were started pending culture results. Hemodialysis was initiated for<br />

worsening kidney function. However, the patient’s condition continued to deteriorate in spite <strong>of</strong><br />

negative blood, CSF and urine cultures. On day 3 <strong>of</strong> admission, a maculopapular rash was noted in the<br />

lower extremities beneath his compression stockings. Further examination revealed sporadic lesions on<br />

his hips and his back, and subsequently an engorged tick was found in his retroscrotal area.<br />

Retrospectively, we elicited a history <strong>of</strong> travel to Vancouver, Canada three months prior to the<br />

admission and recent trip to a state park (Osage Hills) in Oklahoma. Doxycycline was started on<br />

suspicion <strong>of</strong> a tick borne infection and serology was sent for Ehrlichia, Anaplasma, Lyme disease,<br />

Babesiosis and Rickettsia. The tick was identified as a Lone Star tick (Amblyoma americanum). His IgG<br />

titres for Ehrlichia chaffeensis were initially

Singulair (Montelukast) Induced Partial Bowel Obstruction<br />

Monzer Saad, D.O Anil Sil, MD, FRCP, FACP<br />

INTRODUCTION: Singulair is a competitive and selective oral Leukotriene receptor antagonist that<br />

inhibits cysteinyl leukotriene CysLT1 receptor. It is commonly used for the prophylaxis and chronic<br />

treatment <strong>of</strong> asthma, also effective in the treatment <strong>of</strong> allergic rhinitis. Singulair is a safe and effective<br />

drug. Clinical trials showed comparable incidences (less than 1%) <strong>of</strong> angioedema in patients using<br />

singulair versus placebo, and slightly greater incidences <strong>of</strong> abdominal pains in singulair compared to<br />

placebo patients.<br />

CASE PRESENTATION: Patient is a 78 year old male with a past medical history <strong>of</strong> allergic rhinitis,<br />

arthritis, benign prostatic hypertrophy treated with flomax, hyperlipidemia treated with zocor, and a<br />

past surgical history <strong>of</strong> partial splenectomy in 1956, presents complaining <strong>of</strong> sudden onset nausea,<br />

vomiting and diffuse, non-radiating severe abdominal pain. These symptoms started two hours after the<br />

patient took the first pill <strong>of</strong> singulair, which was newly prescribed for his allergic rhinitis. Patient denies<br />

any other systemic symptoms. No history <strong>of</strong> diarrhea, constipations, fever, chills, or similar symptoms.<br />

The patient and his spouse consumed the same diet. His spouse didn’t develop any symptoms. Physical<br />

examination was not significant except for diffuse abdominal tenderness on deep palpation. CT scan <strong>of</strong><br />

the abdomen showed some thickening <strong>of</strong> the distal esophagus. EGD was done that showed gastritis.<br />

Singulair was stopped and the patient was started on intravenous fluids. First, he was given nothing by<br />

mouth, but then advanced to clear liquid/s<strong>of</strong>t diet after having witnessed regular bowel movements.<br />

Shortly after, and without any pharmacological interventions, patient’s symptoms progressively<br />

improved, and he was discharged home with the diagnosis <strong>of</strong> singulair induced angioedema causing<br />

small bowel thickening and resultant partial bowel obstruction.<br />

DISCUSSION: The most commonly seen singulair adverse reactions are: upper respiratory infections,<br />

fever, headaches, pharyngitis, cough, abdominal pain, diarrhea, otitis media, influenza, rhinorrhea, and<br />

sinusitis. This case report exemplifies a singulair induced gastro-intestinal angioedema, which is not<br />

commonly seen or reported. Furthermore, adverse reactions are usually seen after chronic usage <strong>of</strong> this<br />

drug, and it is not usual to be seen after taking only one pill.<br />

Levamisole-Adulterated Cocaine: A case <strong>of</strong> new rash in a cocaine abuser<br />

Tiffany Sanford MD, Violet Asfour MD, Brenda Pellicane MD, Falgun Patel MD, Cecilia Big MD<br />

INTRODUCTION: In the last 15 years, the drug called levamisole has been used as an adulterant in the<br />

production <strong>of</strong> cocaine, with upwards <strong>of</strong> 70% <strong>of</strong> the US cocaine supply contaminated. It is believed that<br />

levamisole can add to the euphoric effect <strong>of</strong> cocaine by prolonging the presence <strong>of</strong> neurotransmitters in<br />

the synapse. Commonly used as a veterinary anti-helminth, levamisole was also used as an<br />

immunomodulatory drug for nephritic syndrome and rheumatoid arthritis. It is now only approved in US<br />

markets as an adjunct medication for use in colon cancer.<br />

CASE PRESENTATION: A 36 year-old woman with a history <strong>of</strong> IV drug abuse, Hepatitis C, and<br />

prostitution presented to the emergency room with a diffuse purple rash. She had fevers, chills and<br />

painful blisters on both knees. The patient was initially diagnosed with a bacterial skin infection and<br />

given antibiotics. After failed outpatient treatment, she returned with large, tender purpuric macules<br />

with erythematous borders. The rash had spread all over the body with central ulceration and crusting<br />

on her bilateral arms, legs, abdomen, face, and lobe <strong>of</strong> ear. Basic metabolic pr<strong>of</strong>ile, LFT, C3, C4, UA were<br />

normal. HIV and Rheumatoid Factor were negative. There was no growth in blood cultures. WBC count<br />

was reduced, while D-Dimer and Fibrinogen were elevated. Urine Drug Screen was positive for opiates<br />

and cocaine. Skin biopsy identified leukocytoclastic vasculitis. Similar presentations <strong>of</strong> leukocytoclastic<br />

vasculitis in cocaine abusers at local hospitals lead to identifying Levamisole toxicity as the probable<br />

cause <strong>of</strong> the purpuric rash.<br />

DISCUSSION: Levamisole, in both medically-indicated and illicit use has been found to have some<br />

dangerous side effects, including agranulocytosis, and leukocytoclastic vasculitis. With drug adulterants<br />

becoming increasingly pervasive, physicians working in areas <strong>of</strong> widespread drug abuse should become<br />

familiar with the stigmata <strong>of</strong> levamisole toxicity - purpuric skin rash and agranulocytosis.<br />

disorders.<br />

CASE PRESENTATION: This is a 62 year old African <strong>American</strong> male with a past medical history <strong>of</strong> right<br />

eye prosthesis since birth, diabetes type 2 and paranoid schizophrenia who presented with sudden<br />

onset left eye blindness. The patient initially had 2 day onset <strong>of</strong> progressively worsening left eye<br />

blindness for which he was referred from the ophthalmologist after the comprehensive eye exam<br />

showed no pathology. He presented to the emergency department and was started on high dose<br />

steroids for questionable temporal arteritis. All routine labs including blood counts and sedimentation<br />

rate, rheumatoid factor, and C reactive protein were normal. The brain imaging was normal excluding<br />

any stroke, vascular pathology, increased intracranial pressure, or tumor. The temporal artery biopsy<br />

was performed which was negative. Subsequently Neurology and Psychiatry were consulted. Psychiatry<br />

thoroughly investigated his personal, and psychosocial history. The patient admitted to having multiple<br />

stressors in the last month including death <strong>of</strong> close family member and a friend, and a sister recently<br />

diagnosed with cancer. He further admitted to having apprehension about living alone and caring for<br />

himself with this bilateral blindness. After thorough case review, the patient was diagnosed with<br />

conversion disorder and psychiatry recommended starting patient on anxiolytics, and antipsychotic<br />

medication along with behavioral psychotherapy. Patient was in agreement with the diagnosis and plan,<br />

and his symptoms slowly began improving with positive reassurance. With in the next 2 days the<br />

patient was able to appreciate perception <strong>of</strong> light and his visual fields improved.<br />

DISCUSSION: Onset <strong>of</strong> Conversion Disorder is usually acute and symptoms are usually <strong>of</strong> short<br />

duration. Approximately 95% remit spontaneously within 2 weeks. Resolution <strong>of</strong> symptoms is usually<br />

spontaneous, although it is probably facilitated by insight oriented supportive or behavioral therapy and<br />

anxiolytics. Good prognosis is associated with acute onset, presence <strong>of</strong> clearly identifiable stressor at<br />

onset, and short interval between onset and institution <strong>of</strong> treatment. Other good prognostic factors<br />

include, above average intelligence, paralysis, aphonia, and blindness. Poor prognosis is associated with<br />

seizures, and tremors.<br />

Thyroid Nodule with a punch: Renal Cell Cancer<br />

Ankur Sharma, MD. Dept <strong>of</strong> Medicine, Sinai Grace Hospital/ DMC, Detroit, MI Second Author: Gard<br />

Edelson, MD. Dept <strong>of</strong> Medicine, Sinai Grace Hospital/ DMC, Detroit, MI<br />

INTRODUCTION: Metastasis to the thyroid is commonly seen in post mortem autopsies in patients’<br />

with malignancies. However, a clinical diagnosis <strong>of</strong> the same is less common. Cancer.Metastatic cancer<br />

<strong>of</strong> the head and neck comprises <strong>of</strong> only 8-14% <strong>of</strong> metastasis from renal carcinoma. Unfortunately, most<br />

cases are diagnosed on autopsy, with the incidence varying from 1.25% to 24%.<br />

CASE PRESENTATION: A patient with history <strong>of</strong> nephrectomy in 1995 for RCC had a CT <strong>of</strong> the chest in<br />

2005, for surveillance <strong>of</strong> lung nodules where a thyroid mass was seen. Ultrasound examination revealed<br />

a 4.9 cm right thyroid mass and subsequent nuclear medicine scan showed large cold nodules. FNA was<br />

consistent with a benign colloid nodule.The patient was started on levothyroxine for asymptomatic<br />

hypothyroidism. In March 2010, a CT chest showed interval increase in size <strong>of</strong> the thyroid. Aspiration <strong>of</strong><br />

the mass was non diagnostic. A repeat biopsy from the dominant nodule showed aggregates <strong>of</strong> thyroid<br />

follicular cells, with minimal degree <strong>of</strong> nuclear enlargement within some follicular cells, suggesting a<br />

follicular lesion. Right thyroid lobectomy was done and pathology identified a capsulated tumor<br />

composed <strong>of</strong> clear cells. Immunohistochemical analysis revealed positive staining for CD10,KIM-1 and<br />

PAX2 and negative for Thyroglobulin and TTF-1 (Thyroid transcription factor 1) consistent with<br />

metastatic renal cell carcinoma.A whole body bone scan revealed no evidence <strong>of</strong> osseous metastatic<br />

disease.<br />

DISCUSSION: A solitary metachronous metastasis in the thyroid from the RCC is exceedingly rare.<br />

However, metastasis to the thyroid is not as unusual as was previously thought. The clinical course <strong>of</strong><br />

renal cell carcinoma and the development <strong>of</strong> metastases may be particularly slow-paced, so far there<br />

are 7 reports on extreme delays in metastasis to the thyroid, ranging from 3 to 26 years.<br />

The interval <strong>of</strong> more than 5 years is long enough to distract the physician’s awareness about the<br />

previously treated malignant disease. Although a thyroid nodule is an extremely common clinical<br />

finding, the new appearance <strong>of</strong> a thyroid nodule in patients with previous malignant disease warrants<br />

prompt cytological evaluation.<br />

One potential source <strong>of</strong> confusion in cytological interpretation is the difficulty <strong>of</strong> distinguishing primary<br />

thyroid anaplastic carcinoma from metastatic high-grade malignancy. Immohistochemical staining <strong>of</strong><br />

renal cell carcinoma has shown expression <strong>of</strong> low-molecular-weight cytokeratin, epithelial membrane<br />

antigen (EMA) and vimentin, but no studies regarding the use <strong>of</strong> these markers has yet been reported.<br />

Management <strong>of</strong> thyroid metastases should depend on the individual situation. There is no clear<br />

consensus. Also, although therapy <strong>of</strong> metastatic malignancies is <strong>of</strong>ten considered to be palliative,<br />

aggressive surgical treatment in isolated cases may be curative and <strong>of</strong> clear survival benefit.<br />

INTRODUCTION: Anti-neutrophil cytoplasmic antibodies (ANCA) play an important role in the patho<br />

physiology <strong>of</strong> Churg Strauss syndrome, microscopic polyangiitis, Wegener’s granulomatosis and related<br />

forms <strong>of</strong> vasculitis. Rituximab is a monoclonal antibody against the CD 20 antigen on B – lymphocytes<br />

and activates complement dependent B-cell cytotoxicity.<br />

CASE PRESENTATION: A 54 year old female with a past medical history <strong>of</strong> anemia, recurrent sinus<br />

congestion, and gastro esophageal reflux disease presented with generalized weakness and fatigue,<br />

associated with nausea, vomiting, decreased oral intake, acute kidney injury with increasing Creatinine<br />

levels. Rheumatology workup revealed positive CANCA. Patient was immediately started on high dose<br />

steroids and azathioprine. Azathioprine was discontinued because <strong>of</strong> worsening renal failure and<br />

cyclophosphamide was started. The patient showed symptomatic improvement and was discharged.<br />

However, she was readmitted because <strong>of</strong> recurrent anemia and worsening renal function, with<br />

increasing Creatinine levels. Cyclophosphamide was discontinued, and she was started on Rituximab.<br />

The patient improved symptomatically with fewer side effects, did not develop any complications and<br />

has been following up with her primary care physician and rheumatologist for the last seven months and<br />

is currently doing well.<br />

DISCUSSION: Two prospective randomized controlled trials published in May 2011 have shown that<br />

Rituximab can be used in induction therapy in active ANCA associated vasculitis. The safety pr<strong>of</strong>ile <strong>of</strong><br />

Rituximab is favorable when compared to steroids and cyclophosphamide. According to a randomized<br />

controlled trial published in 2010, Rituximab based regimen was not superior to standard<br />

cyclophosphamide therapy for severe ANCA associated vasculitis.<br />

Rituximab may represent a promising new drug for treatment <strong>of</strong> patients with ANCA-associated<br />

vasculitis in whom either standard therapy has failed or contraindicated. On April 19, 2011 the FDA<br />

approved Rituximab (Rituxan) combined with glucocorticoids for the treatment <strong>of</strong> adult patients with<br />

granulomatosis with polyangiitis (GPA; Wegener’s granulomatosis) or microscopic polyangiitis<br />

(MPA). More research is warranted to determine the overall efficacy <strong>of</strong> the drug.<br />

Severe Encephalopathy and Impending Cerebral Herniation in Acetaminophen Toxicity: Recovery with a<br />

Novel Hypernatremic/Hypothermic Protocol<br />

Jessie L. K. Roske, MD Second Author: William T. Browne, MD<br />

INTRODUCTION: Acute liver failure affects approximately 2000 persons in the U.S. each year; 39% <strong>of</strong><br />

these cases are related to acetaminophen overdose. Survival rates for ALF without transplantation range<br />

from 17-68%, although acetaminophen overdose has the lowest mortality rate. A substantial number <strong>of</strong><br />

patients die waiting for liver transplantation and another segment <strong>of</strong> the patient population is never<br />

listed. As a transplant center, the challenging clinical situation <strong>of</strong> acetaminophen-induced acute liver<br />

failure in patients deemed not to be transplant candidates is encountered all too <strong>of</strong>ten. For those<br />

ineligible for or awaiting transplantation, care focuses on supportive care in an extremely complex<br />

critical illness that can rapidly devolve. Causes <strong>of</strong> death include cerebral edema, multi-organ failure,<br />

sepsis, cardiac arrest, and respiratory failure. Efforts to improve survival are as essential as they are<br />

challenging in this life-threatening multi-system disease process.<br />

CASE PRESENTATION: A 37-year-old female with a past medical history significant for alcohol<br />

dependence presented with encephalopathy, coagulopathy and hyperbilirubinemia and was found to<br />

have a toxic acetaminophen level 48 hours after ingestion. Given refractory alcoholism with multiple<br />

failed courses <strong>of</strong> substance abuse treatment, the patient was considered not a candidate for liver<br />

transplantation. The patient’s neurologic status deteriorated with evidence <strong>of</strong> impending central<br />

herniation including extensor posturing, sustained clonus and bilateral Babinski sign. In an effort to<br />

avoid catastrophic neurologic sequelae, hypernatremia to 165mmol/L and hypothermia to 32°C were<br />

urgently induced. Additional complications during the ICU stay included acute anuric renal failure<br />

requiring renal replacement therapy and further derangement in liver function tests with undetectably<br />

elevated INR. Given markedly elevated INR, placement <strong>of</strong> ICP monitor was felt to be contraindicated.<br />

Continuous renal replacement therapy was utilized for maintenance <strong>of</strong> hypernatremia. Ultimately, in the<br />

absence <strong>of</strong> direct ICP measurement, the patient was cooled for a total <strong>of</strong> 6 days, with timing <strong>of</strong><br />

rewarming based on improving neurologic exam, corresponding improvement in liver function, and<br />

serial head CT scans. The patient was subsequently extubated and discharged on hospital day 32 with<br />

complete neurologic recovery and improving hepatic function.<br />

DISCUSSION: In review <strong>of</strong> the literature, the methods employed in this case are described individually<br />

but to our knowledge no similar protocol has been previously presented with case experience. In this<br />

very challenging case, the efforts <strong>of</strong> a multidisciplinary team to extrapolate clinical experience and<br />

limited published literature to develop a novel induced hypernatremia/hypothermia protocol produced<br />

an extremely satisfactory outcome.<br />

Cardiovascular Diseases, Mayo Clinic, Rochester, MN<br />

INTRODUCTION: Cardiac tumors may remain asymptomatic until incidental discovery or present with<br />

various signs including those <strong>of</strong> systemic embolization. They must therefore be considered in the<br />

evaluation for a cardiogenic etiology <strong>of</strong> neurologic deficits.<br />

CASE PRESENTATION: A 46-year-old female with major depressive disorder and tobacco abuse<br />

presented to her local emergency department with sudden onset right arm and hand weakness. Five<br />

months prior she had started estrogen replacement therapy following gynecologic surgery for benign<br />

reasons. She noted difficulty lifting her right arm to smoke a cigarette earlier that morning but<br />

nonetheless accompanied her husband to his doctor’s appointment. However, she became concerned<br />

while leafing through a stroke pamphlet and decided to seek evaluation. On arrival to the ED, symptoms<br />

had been present for six hours. Physical exam demonstrated significant weakness <strong>of</strong> the right upper<br />

extremity distal to the shoulder. Cardiac exam was unremarkable. Electrocardiogram displayed normal<br />

sinus rhythm, and a non-contrast CT scan <strong>of</strong> the head was negative. She was admitted to the Neurology<br />

service where, three days later, she underwent MRI <strong>of</strong> the head due to persistent deficits. This<br />

demonstrated multifocal punctate acute lacunar infarcts throughout the left temporal, parietal,<br />

occipital, and frontal lobes as well as the left caudate head and left basal ganglia. These findings were<br />

felt to be highly suggestive <strong>of</strong> proximal embolic phenomena. Transthoracic echocardiogram (TEE)<br />

showed a 2.2 x 1.0 cm serpiginous appearing mobile left atrial mass attached to the junction <strong>of</strong> the atrial<br />

septum and posterior left atrial wall. Given concern for thrombus, Cardiology advised starting IV<br />

heparin. Further studies including serum and urine protein electrophoresis and hypercoagulable workup<br />

were unremarkable. Holter monitoring was negative for arrhythmia. A cardiac MRI was obtained to<br />

further define the lesion but visualized no intracardiac mass or thrombus. By day five <strong>of</strong> hospitalization<br />

the patient’s neurologic exam had normalized. Repeat TEE demonstrated a 6.0 x 6.0 mm sessile left<br />

atrial mass. Three days later the patient underwent excision <strong>of</strong> a 1.0 x 1.0 cm left atrial myxoma via<br />

biatrial approach. Follow-up TEE was reassuring, and she was dismissed from the hospital. Her postoperative<br />

course was complicated by atrial fibrillation requiring TEE-guided cardioversion.<br />

DISCUSSION: While the majority <strong>of</strong> presenting symptoms <strong>of</strong> atrial myxoma are cardiovascular, nearly<br />

twenty percent <strong>of</strong> patients have neurologic deficits due to embolization <strong>of</strong> tumor fragments or thrombi.<br />

Differentiation between tumor and thrombus can be difficult by noninvasive imaging techniques.<br />

However, once a presumptive diagnosis <strong>of</strong> myxoma is made, prompt resection is required.<br />

An unusual complication <strong>of</strong> a routine abdominal work-out<br />

Elena N Kazimirko, MD; Christopher Wittich, MD<br />

INTRODUCTION:Spontaneous rectus sheath hematoma arises from rupture <strong>of</strong> epigastric vessels and<br />

usually presents in setting <strong>of</strong> trauma, or anti-coagulation. It is a relatively rare disorder in the clinical<br />

setting, and <strong>of</strong>ten difficult to distinguish from other abdominal pathologies, and therefore is <strong>of</strong>ten<br />

misdiagnosed.<br />

CASE PRESENTATION: A 59 year old female with a past medical history significant for chronic kidney<br />

disease due to autosomal dominant polycystic kidney disease, living related donor transplant in January<br />

<strong>of</strong> 2009, presented for evaluation <strong>of</strong> acute abdominal pain. The patient was in her usual state <strong>of</strong> health<br />

until the day <strong>of</strong> presentation. She had done upper body and abdominal exercises and crunches in the<br />

morning and around 11 am developed a sudden sharp, “spasm”-like pain located supra-pubically with<br />

right sided-predominance. She described a progression in severity <strong>of</strong> pain until arrival to the Emergency<br />

Department around 2 p.m. She was also experiencing nausea with one episode <strong>of</strong> non-bilious, nonbloody<br />

emesis that occurred in the emergency department. The patient denied any fevers, back pain,<br />

hematuria, urinary burning or frequency. Patient’s medications included aspirin 81 mg, antihypertensives<br />

and immunosuppressive therapy. Physical examination showed a female that appeared to<br />

be well-nourished, well appearing, slightly drowsy with normal heart and lung examination. Abdominal<br />

examination revealed no evidence <strong>of</strong> ecchymoses, normal bowel sounds, and moderate to severe<br />

tenderness and voluntary guarding over RLQ and supra-pubically, with fullness on palpation. Further<br />

mass was in left pelvic area consistent with patient’s transplanted kidney. No rebound tenderness was<br />

found and Carnett’s sign was found to be positive. The patient’s blood work revealed a normal CBC with<br />

differential, electrolyte panel consistent with patient’s chronic kidney disease as well as normal liver<br />

function tests. The patient required significant opioid medication for pain control. CT scan <strong>of</strong> the<br />

abdomen was pursued and revealed 4.6 *8.4 *12.3 cm right rectus sheath hematoma. The patient was<br />

admitted to a general medicine service to monitor for evidence <strong>of</strong> further bleeding. The patient’s<br />

showed blood loss on Hemoglobin monitoring, with lowest Hemoglobin <strong>of</strong> 11.1 g/dL (baseline 13.2).<br />

Prothrombin time and activated partial thromboplastin time were found to be within normal limits. The<br />

patient’s vital signs remained stable, plateau <strong>of</strong> anemia reached, and ecchymosis became evident over<br />

the right lower abdomen. The patient was discharged home with weight bearing and physical activity<br />

limitations. On follow up, the patient had no further complications.<br />

DISCUSSION: Rectus sheath hematoma should be considered in previously asymptomatic individuals<br />

with acute onset abdominal pain, localized to rectus sheath with a positive Carnett’s sign and a palpable<br />

mass. The physical exam maneuver, known as Carnett’s sign can be a diagnostic. Early diagnosis may<br />

avoid unnecessary testing or invasive procedures.<br />

Dermatomyositis: A Diagnosis Not Easy to Swallow<br />

Mary C Drinane, MBChB Second Author: Anna Svatikova, MD Third Author: John Schoolmeester, MD<br />

Last Author: William Ward, MD<br />

INTRODUCTION: Dermatomyositis is an inflammatory myositis classically presenting in middle-aged<br />

patients with an insidious proximal muscle weakness and characteristic skin findings. Dysphagia is a<br />

known complication <strong>of</strong> inflammatory myositis and can be the presenting symptom prior to clinically<br />

evident myopathy or biochemical evidence <strong>of</strong> myositis. This case highlights that inflammatory myositis is<br />

an important consideration in patients with idiopathic dysphagia.<br />

CASE PRESENTATION: An 84 year old woman presented with progressive dysphagia over one week.<br />

Difficulty swallowing began with solids only, and soon included liquids and episodes <strong>of</strong> nasopharyngeal<br />

regurgitation. She had no other neurological symptoms or neurologic exam findings at time <strong>of</strong><br />

presentation. She had a heliotrope rash around both eyes and Gottron's sign over her MCP joints. CT<br />

brain was negative for hemorrhage, mass, or acute ischemia. Swallow study showed pooling in the<br />

vallecula with penetration <strong>of</strong> the trachea and weak cough. She had an elevated CK (346 U/L), aldolase<br />

(11 U/L), and AST (64 U/L). ANA was positive with a weakly positive SCL-70 and antimitochondrial<br />

antibody. EMG showed evidence <strong>of</strong> a mild proximal myopathy involving upper limbs greater than lower<br />

limbs, without compelling evidence <strong>of</strong> accompanying fiber splitting, vacuolation or necrosis. Shave<br />

biopsy <strong>of</strong> a papule on her left 3 rd MCP showed interface vacuolar dermatitis and stained positive for<br />

ANA, IgG, and IgM, consistent with dermatomyositis. Investigations for underlying malignancy including<br />

EGD, colonoscopy, and CT chest, abdomen, and pelvis were negative. She was treated with 30 mg <strong>of</strong><br />

prednisone daily and a five day course <strong>of</strong> IV immunoglobin. After three weeks <strong>of</strong> treatment, her<br />

symptoms were improved, and a repeat swallow study showed improvement in her swallow with<br />

penetration to the vocal cords only with thin consistency.<br />

DISCUSSION: Dysphagia is a recognized complication <strong>of</strong> inflammatory myositis. It usually manifests<br />

with pharyngeal regurgitation, due to weakening <strong>of</strong> oropharyngeal muscles and striated muscle in the<br />

upper one third <strong>of</strong> the esophagus. Esophageal involvement eventually develops in over one third <strong>of</strong><br />

elderly patients with dermatomyositis. However, there is no published description <strong>of</strong> dysphagia as the<br />

presenting symptom <strong>of</strong> dermatomyositis, as it was in this case. Of inflammatory myositis subtypes,<br />

inclusion body myositis presents most frequently with dysphagia, in 21-69% <strong>of</strong> cases. Treatments<br />

include immunosuppression <strong>of</strong> the underlying myositis, myotomy, dilation, or Botox injection. Physical<br />

therapy has also been used, but its efficacy is not well established. Malignancy has been noted to occur<br />

in 47.8% <strong>of</strong> elderly patients with dermatomyositis compared to 9.1% in patients under the age <strong>of</strong> 65. In<br />

patients with dermatomyositis, dysphagia is associated with poor prognosis, a 31% 1 year mortality.<br />

A Woman With Blurred Vision Who Didn’t Know 'HACEK' She Was<br />

Evan L Hardegree, MD, Shaina A Rozell, MD, MPH, Walter R Wilson, MD<br />

INTRODUCTION:Infective endocarditis (IE) may present with myriad embolic phenomena affecting<br />

seemingly disparate organ systems, potentially leading to delayed diagnosis. Thus in high-risk patients,<br />

such as those with congenital heart disease or prosthetic heart valves, there should be a low threshold<br />

to investigate for IE.<br />

CASE PRESENTATION: A 40-year-old woman presented after one week <strong>of</strong> fevers, left eye irritation and<br />

blurred vision. Systems review revealed new exposure to cats for the previous 3 weeks. Her history<br />

included congenitally-corrected transposition <strong>of</strong> the great arteries and implantation <strong>of</strong> a mechanical<br />

tricuspid valve at age 13. Physical examination was notable only for crisp mechanical heart sounds and<br />

left periorbital erythema with scleral injection. Retinal examination revealed vitreous opacities and<br />

retinitis. Given her feline exposure, she was treated empirically for ocular toxoplasmosis with<br />

trimethoprim/sulfamethoxazole and steroid eye drops. Toxoplasma serology and blood cultures were<br />

drawn, and aqueous humor was aspirated and sent for cultures and toxoplasma testing.<br />

Five days later, she was seen in Ophthalmology with worsening vision and intermittent fevers.<br />

Toxoplasma serologies, blood cultures, and ocular microbiologic testing returned negative. The following<br />

day, one <strong>of</strong> six blood culture bottles returned positive for Haemophilus aphrophilus. This raised concern<br />

for IE with secondary endophthalmitis. She underwent transesophageal echocardiography, revealing a 5<br />

x 10mm subvalvular vegetation consistent with IE. Thus she was admitted for initiation <strong>of</strong> intravenous<br />

ceftriaxone. Ophthalmology diagnosed her with bacterial endophthalmitis and performed vitrectomy<br />

with intravitreous injection <strong>of</strong> ceftriaxone, vancomycin, and clindamycin.<br />

Unfortunately, the patient’s left eye vision did not fully recover. Nonetheless, she defervesced, her<br />

blood cultures became negative, and she was dismissed from the hospital to complete a six-week course<br />

<strong>of</strong> ceftriaxone.<br />

DISCUSSION: While most cases <strong>of</strong> prosthetic valve IE are due to Staphylococci, Streptococci, and<br />

Enterococci, the HACEK organisms (Haemophilus, Actinobacillus, Cardiobacterium, Eikenella, and<br />

Kingella) are fastidious, gram-negative organisms which cause 5 to 10% <strong>of</strong> cases.<br />

Our patient’s congenital heart disease and prosthetic valve predisposed her to IE. The organism was<br />

Haemophilus aphrophilus, which may also cause orthopedic infections, meningitis, brain abscess, and<br />

empyema. As this organism grows slowly, patients <strong>of</strong>ten present subacutely after long periods <strong>of</strong><br />

bacteremia, allowing formation <strong>of</strong> large vegetations and subsequent embolization. Interestingly,<br />

concurrent IE and endophthalmitis due to H. aphrophilus has not previously been reported.<br />

Treatment <strong>of</strong> HACEK prosthetic valve IE consists <strong>of</strong> 6 weeks <strong>of</strong> intravenous therapy with a 3 rd - or<br />

4 th -generation cephalosporin, ampicillin-sulbactam, or cipr<strong>of</strong>loxacin. Bacterial endophthalmitis is treated<br />

with surgical vitrectomy and intravitreous antibiotics. Prognosis is fair with HACEK group IE, with an<br />

estimated mortality <strong>of</strong> 10-15%. Visual outcomes following endophthalmitis are difficult to predict,<br />

with slow recovery taking place over several months as intraocular inflammation resolves.<br />

Livia L Hegerova, MD<br />

INTRODUCTION: It is estimated that up to 50% <strong>of</strong> patients with brain lesions have psychiatric<br />

manifestations. Specifically, frontal lobe lesions are associated with nearly 90% <strong>of</strong> these psychiatric<br />

symptoms. The specific psychiatric symptoms are dependent on the location within the brain and<br />

amount <strong>of</strong> mass effect or direct invasion.<br />

CASE PRESENTATION: A 65 year old man with a history <strong>of</strong> prostate cancer was admitted with<br />

complaints <strong>of</strong> a three day history <strong>of</strong> leg weakness and loss <strong>of</strong> peri-rectal sensation. He was originally<br />

diagnosed with Stage IV prostate cancer six months earlier. At that time, he presented with an elevated<br />

PSA, multiple painful bony, and spinal epidural metastases. He was receiving hormonal treatment with<br />

Lupron. At the time <strong>of</strong> this hospitalization, MRI thoracic and lumbar spine revealed progressive<br />

metastatic disease from L4 through T4. Due to these findings, he was started on a course <strong>of</strong> steroids<br />

and spinal radiation.<br />

While undergoing treatment for spinal cord compression, it was noted that the patient was acting<br />

bizarre. His behavior was uninhibited, including use <strong>of</strong> pr<strong>of</strong>ane language and wearing inappropriately<br />

little clothing. His wife reported this behavior was new and requested imaging <strong>of</strong> his brain. She felt her<br />

husband had been acting unusual with frequent irritable outbursts and occasionally slurring words.<br />

Due to this altered mental status a brain MRI was performed which revealed a single dural metastases<br />

overlying the left frontal lobe. This mass was noted to result in mass effect and small left frontoparietal<br />

subdural effusion. Due to the presence <strong>of</strong> psychiatric abnormalities, treatment was initiated with IV<br />

dexamethasone. stereotactic gamma knife, and docetaxel.<br />

DISCUSSION: The link between the frontal lobes and emotion draws back to the 1800s with the case <strong>of</strong><br />

Phineas Gage. Changes in personality, intellect, uncoordinated walking, loss <strong>of</strong> smell, and speech<br />

difficulties are encountered with frontal lobe tumors. Prostate and breast cancers typically lead to dural<br />

brain metastases. In contrast, parenchymal brain metastases occur most commonly with lung, breast<br />

and renal cancer. The case is a reminder that a seemingly difficult patient may carry more than a bad<br />

attitude and family may be the key to identify subtle personality changes.<br />

Recurrent Unexplained Ascites: A Harbinger <strong>of</strong> Evil<br />

Shiao Yen Khoo, MD Second Author: Jason Post, MD<br />

INTRODUCTION:Recurrent ascites <strong>of</strong> unknown etiology is an uncommon occurrence and could be an<br />

indicator <strong>of</strong> peritoneal carcinomatosis.<br />

CASE PRESENTATION: We report a case <strong>of</strong> a 52-year-old man with cold agglutinin syndrome and<br />

antiphospholipid antibody syndrome maintained on anticoagulation and chronic immunosuppressant<br />

therapy who presented with 5 months <strong>of</strong> recurrent ascites associated with partial small bowel<br />

obstructions and an unintentional 30 pound weight loss in 6 months. Prior investigations included 3<br />

diagnostic and therapeutic paracentesis amounting to 9 liters with serum ascites albumin gradients > 1.1<br />

g/dL, total ascitic protein > 1 gm/dL and negative cytology repeatedly. On presentation, his vital signs<br />

were normal and physical examination was remarkable only for ascites. A fourth paracentesis was done<br />

and was significant for 1068 white blood cells/mm3, with 1% neutrophils and 15% lymphocytes. Ascitic<br />

fluid to ascites LDH ratio was < 1.0. Extensive work-up included a normal transthoracic echocardiogram;<br />

abdominal ultrasound that showed patent portal vessels; FNA <strong>of</strong> the liver with normal tissue on<br />

pathology; mildly positive ANA, but negative ENA; and negative infectious work-up including negative<br />

ascitic fluid cultures, ascitic fluid mycobacterial PCR, fungal serologies, hepatitis screen, HIV and blood<br />

cultures. PET/CT revealed only minimal diffuse peritoneal FDG uptake indicative <strong>of</strong> peritonitis. He<br />

underwent explorative laparoscopy, which was evident for peritoneal carcinomatosis with malignant<br />

adhesions requiring extensive adhesiolysis, laparotomy and creation <strong>of</strong> a diverting loop ileostomy.<br />

Pathology was consistent with a poorly differentiated adenocarcinoma with an unknown primary. He<br />

deteriorated clinically soon after, suffering from multi-organ failure. He was transitioned to comfort<br />

cares only on hospital day 26 at the request <strong>of</strong> his family and passed away peacefully on hospital day 35.<br />

Final autopsy report revealed primary appendiceal adenocarcinoma with peritoneal carcinomatosis.<br />

DISCUSSION: Recurrent ascites <strong>of</strong> unknown etiology is uncommon and could be an indicator <strong>of</strong><br />

malignancy-related ascites especially in the setting <strong>of</strong> weight loss. Ascitic fluid analysis is key in<br />

establishing the diagnosis; however, the overall sensitivity <strong>of</strong> cytology smears is 58-75% depending on<br />

the processing quality. Peritoneal carcinomatosis accounts for approximately two-thirds <strong>of</strong> patients with<br />

malignancy-related ascites. When large volume paracentesis is non-diagnostic, an open laparotomy with<br />

omental biopsies can be helpful in diagnosing peritoneal carcinomatosis.<br />

INTRODUCTION: Background<br />

Endogenous bacterial endophthalmitis (EBE), a rare condition, results from the spread <strong>of</strong> pathogens<br />

from a remote focus and is an ocular emergency requiring urgent treatment to prevent significant visual<br />

loss. EBE carries a poor prognosis with bilateral involvement in 25%. 78% and 29% are left with<br />

maximum 20/400 vision or enucleation/evisceration, respectively. The main prognostic factors are<br />

pathogen virulence, host-immunity and time to diagnosis. Two-thirds <strong>of</strong> cases have predisposing factors<br />

(diabetes mellitus, valvular heart disease, recent surgery, IV drug abuse, immunosuppression). The<br />

commonest source in the U.S. is endocarditis.<br />

CASE PRESENTATION: A 62-year-old woman with poorly controlled type-2 diabetes mellitus and<br />

chronic kidney disease sought medical attention for acute visual change. She developed isolated low<br />

back and left hip pain two weeks earlier. Four days prior to presentation, she developed right eye<br />

teichopsia. An optometrist diagnosed anterior uveitis; tobramycin, prednisone and cyclopentolate were<br />

prescribed. Later, she developed photophobia and deep right eye pain with complete blindness the day<br />

<strong>of</strong> presentation. There was no history <strong>of</strong> trauma or glaucoma. She reported progressive left knee pain.<br />

On examination, vital signs were normal. Musculoskeletal examination revealed left knee erythema,<br />

swelling, and pain with passive and active movement, L3-4 spinal tenderness and left ankle Charcot’s<br />

joint. Right eye examination revealed 2.6mm hypopyon, conjunctival injection temporally with<br />

subconjunctival hemorrhage inferiorly, no light perception, anterior chamber cells and flare with retinal<br />

detachment and raised intraocular pressure. Laboratory testing showed Hb 8.2g/dL, WCC 27.2x10(9)/L,<br />

creatinine 2.3mg/dL, BUN 79mg/dL, ESR 44mm/hour.<br />

Based on examination findings, rapid progression, leucocytosis and immunosuppression, endogenous<br />

endophthalmitis was diagnosed. Blood cultures were obtained. She was commenced on systemic<br />

parenteral and intraocular antibiotic therapy with vancomycin, ceftazidime and<br />

fluconazole. Investigation to identify the source revealed left iliopsoas abscess with L3/L4 vertebral<br />

body osteomyelitis. Transesophageal echocardiogram was negative for endocarditis.<br />

DISCUSSION: In contrast to exogenous endophthalmitis, systemic cultures are needed in addition to<br />

vitreal samples for EBE. However, while ocular cultures are less <strong>of</strong>ten positive, they may be the only<br />

source <strong>of</strong> growth. Streptococcus species and Staphylococcus aureus are the commonest pathogens, the<br />

latter commonly resulting in bilateral endophthalmitis.The cornerstone <strong>of</strong> management is intravitreal<br />

antibiotics, vitrectomy and early systemic antibiotic therapy (preventing continued bacteremia,<br />

protecting the unaffected eye). Topical corticosteroids and cycloplegia play a role, preventing<br />

inflammatory ocular sequelae. 50% <strong>of</strong> EBE have no systemic symptoms frequently leading to<br />

misdiagnosis, as uveitis. As our case exemplifies, prompt recognition, management and referral to<br />

ophthalmology by the internist is critical in avoiding devastating consequences. Endogenous<br />

endophthalmitis should be considered in any patient complaining <strong>of</strong> decreased vision or eye pain in the<br />

setting <strong>of</strong> possible bacteremia.<br />

A Whole Hearted Welcome To The United States - Health Globalization And Resurgence Of Eisenmenger<br />

Syndrome<br />

Yoel Korenfeld, MD<br />

INTRODUCTION: Eisenmenger Syndrome (ES) is a complication <strong>of</strong> congenital heart disease with<br />

reversed shunting secondary to severe pulmonary hypertension. Most patients with ES survive to<br />

adulthood and require management <strong>of</strong> this multisystem disease. We present a newly diagnosed case <strong>of</strong><br />

a woman from Macedonia who moved to the United States 2 months prior to presenting with syncope<br />

secondary to ES as a complication <strong>of</strong> a large atrial septal defect.<br />

CASE PRESENTATION: The patient is a 26 year old woman who moved to the US from Macedonia 2<br />

months prior to presenting with syncope to a suburban ED. She had been having dyspnea on exertion<br />

and lightheadedness for 1 month. Before these symptoms started she was healthy and was not taking<br />

any medications. She used to play sports in high school without any symptoms. On physical exam her<br />

blood pressure was mildly elevated at 135/95 mmHg. Heart rate was 62, respiratory rate was 16, and<br />

temperature was 98.5ºF. Her pulse oximetry was low at 82%. Her body mass index was 37 kg/m2. She<br />

was in no respiratory distress. She was noted to be diffusely cyanotic. Her lungs had diffuse bilateral<br />

crackles in the bases. Cardiac exam revealed a very loud pulmonary component <strong>of</strong> the second heart<br />

sound but no murmur was heard. Abdomen was obese with diffuse tenderness; no hepatomegaly was<br />

observed. She had clubbing <strong>of</strong> fingers and toes. Pulses were equal and symmetric in four extremities.<br />

Laboratories showed hemoglobin 24.1 g/dL and hematocrit 74.6%. Uric acid was 12.6 mg/dL and iron<br />

deficiency was confirmed. An electrocardiogram showed biatrial enlargement, QRS right axis deviation<br />

and right ventricular hypertrophy. Both an echocardiogram and MRI showed a large 16 mm atrial septal<br />

defect with right to left shunt. A right heart catheterization showed pulmonary pressure 140/74 mmHg<br />

and pulmonary vascular resistance 24 Wood units. These values did not change with nitric oxide.<br />

Phlebotomy improved hyperviscosity symptoms. The patient developed gout. She was started on<br />

tadalafil and oxygen at night. A month after presentation her symptoms were dramatically improved.<br />

Oral contraception was started.<br />

DISCUSSION: An increase in immigration from developing areas will likely increase the incidence <strong>of</strong> ES<br />

in industrialized countries. We present a case <strong>of</strong> ES secondary to atrial septal defect that was never<br />

diagnosed in childhood. This patient presented with all the associated multisystem effects <strong>of</strong> ES. It is<br />

important that internists are familiar with ES and its management as more patients with ES will likely<br />

present to our clinics in the near future.<br />

A Rare Case <strong>of</strong> Native Aortic Valve Pseudomonas Endocarditis<br />

Nicole M Loo, MD Second Author: Roger L. Click, MD Third Author: Barry L. Karon, MD<br />

INTRODUCTION: CASE PRESENTATION: A 47 year-old Caucasian male with autosomal dominant<br />

polycystic kidney disease complicated by end-stage renal disease on hemodialysis via fistula was<br />

undergoing routine evaluation for renal transplant. He reported new exertional dyspnea and a<br />

dobutamine stress echocardiogram revealed native aortic valve thickening, possible vegetations, and<br />

severe aortic regurgitation. He was admitted to the hospital for presumed native aortic valve infective<br />

endocarditis.<br />

Two months prior he had new onset fevers and painful left testicular edema, and was hospitalized at an<br />

outside facility for epididymitis with pan-sensitive Pseudomonas aeruginosa bacteremia. This was<br />

treated with IV antibiotics plus 4 weeks <strong>of</strong> oral lev<strong>of</strong>loxacin. He initially improved, but within a week <strong>of</strong><br />

finishing his antibiotic course, he had recurrence <strong>of</strong> his symptoms. Repeat blood cultures again showed<br />

pan-sensitive Pseudomonas aeruginosa. A 2 week course <strong>of</strong> oral lev<strong>of</strong>loxacin followed by a 3 week<br />

course <strong>of</strong> oral cipr<strong>of</strong>loxacin was prescribed (the change was due to medication costs). This treatment<br />

resolved his fevers and testicular swelling, and he had just finished the antibiotic course prior to the<br />

renal transplant evaluation visit.<br />

Transesophageal echocardiogram at admission confirmed a flail aortic valve leaflet with severe aortic<br />

regurgitation, mobile aortic valve echodensities >10 mm, and no perivalvular spread <strong>of</strong><br />

infection. Empiric antibiotics were held as he remained afebrile, hemodynamically stable, and did not<br />

demonstrate leukocytosis, bacteremia, or urinary tract infection. Testicular and transrectal ultrasound<br />

revealed fluid collections in his left epididymis region (2.5 x 3 x 2.5 cm) and prostate. The prostate fluid<br />

collection was small in the setting <strong>of</strong> a normal PSA. Urology recommended conservative management<br />

and oral cipr<strong>of</strong>loxacin was restarted.<br />

By hospital day #4-5, one blood culture set grew quinolone-resistant Pseudomonas aeruginosa at 32.66<br />

hours. Infectious Diseases recommended dual therapy with IV meropenem and tobramycin in addition<br />

to aspiration <strong>of</strong> his prostate fluid collection. Prostatic fluid was gram stain and culture negative. After<br />

much discussion amongst Cardiovascular Surgery, Urology, and Infectious Diseases, a prophylactic left<br />

orchiectomy was performed to aid bacteremia clearance, a priority in the setting <strong>of</strong> incipient aortic valve<br />

replacement. He remained stable during an additional 6 weeks <strong>of</strong> antibiotics and then underwent aortic<br />

valve replacement. Unfortunately, he was found to have culture positive Pseudomonas annular abscess<br />

near the right cusp <strong>of</strong> the aortic valve during surgery and required another 6 week course <strong>of</strong> antibiotics.<br />

DISCUSSION: Pseudomonas aeruginosa endocarditis is rare, usually occurring in IV drug users with<br />

prosthetic valve or tricuspid valve involvement. In this case, native aortic valve Pseudomonas<br />

endocarditis due to epididymitis is reported, with no evidence based medicine or case series to guide<br />

decision-making regarding prophylactic orchiectomy for bacteremia clearance.<br />

HSV viremia & hepatitis presenting as febrile neutropenia<br />

Jasmine R Marcelin, MD Jason M Jones, M.D., Brian A. Costello, M.D.<br />

INTRODUCTION: INTRODUCTION: Acute liver failure is <strong>of</strong>ten serious and can be a life-threatening<br />

condition. It is characterized by the rapid onset <strong>of</strong> structural liver injury (manifested by sudden rise in<br />

liver enzymes) and acute functional injury (manifested by decreased protein metabolism) leading to<br />

encephalopathy. The challenge to physicians is to recognize early structural injury, intervening<br />

successfully before function begins to decline.<br />

CASE PRESENTATION: Case Description: A 41 year old female with a history <strong>of</strong> stage 1 invasive ductal<br />

carcinoma <strong>of</strong> the breast underwent wide local excision. Oncotype Dx testing revealed high recurrence<br />

score and therefore, she received adjuvant chemotherapy with docetaxel and cyclophosphamide. She<br />

presented 4 days after her second cycle <strong>of</strong> chemotherapy with febrile neutropenia and a sore<br />

throat. The patient was admitted to the hospital, pan-cultured and started on intravenous antibiotics.<br />

Physical exam revealed fever, tachycardia, tachypnea, and clear lung fields. Chest X-ray, rapid strep<br />

test, blood and urine cultures were negative. Despite treatment with cefepime, vancomycin,<br />

lev<strong>of</strong>loxacin and metronidazole, the patient remained febrile with fevers occurring in a cyclic pattern. In<br />

addition, the patient developed aphthous ulcers as well as a plaque-like lesion concerning for fungal<br />

infection and casp<strong>of</strong>ungin was initiated. Ultimately, the patient developed right upper quadrant pain,<br />

and AST and ALT were found to be rising. These peaked at 1701 and 871, respectively. Casp<strong>of</strong>ungin was<br />

discontinued and Hepatitis A, B, and C, CMV, EBV, and parvovirus screening was negative. Serum HSV 1<br />

PCR and swab <strong>of</strong> the oral ulcers for HSV were positive. Antibiotics were discontinued and the patient<br />

was started on IV acyclovir. The patient’s fever, right upper quadrant pain and transaminases improved<br />

over the first 48 hours. The patient was discharged on 4 weeks total acyclovir with complete resolution<br />

<strong>of</strong> her symptoms and normalizing transaminases.<br />

DISCUSSION: DISCUSSION: Liver transaminases elevated to the thousands typically generate a<br />

differential diagnosis <strong>of</strong> acetaminophen toxicity, hepatitis virus infection or ischemic liver disease. Nonhepatitis<br />

viruses are less common but must also be considered, especially in an immunocompromised<br />

patient, in whom HSV viremia can be rapidly fatal. In this case, correlation <strong>of</strong> the mouth ulcers and acute<br />

hepatitis with the laboratory finding <strong>of</strong> viremia prompted initiation <strong>of</strong> acyclovir and reversed the<br />

impending liver failure. However, diagnosis was delayed until these physical signs became evident. This<br />

case underscores the value <strong>of</strong> a thorough history and physical in combination with a broad differential in<br />

the diagnosis <strong>of</strong> acute liver failure. In addition, this case highlights the value in testing for other viral<br />

causes <strong>of</strong> liver failure, including HSV, EBV, parvovirus and CMV, in immunocompromised patients.<br />

Yersinia Enterocolitis Presenting As Acute Cholecystitis<br />

Eric M Nelsen, MD Second author: Madhusudan Grover, MD Third author: Amindra S. Arora, MD<br />

INTRODUCTION: Yersinia Enterocolitica is known to cause infectious ileocolitis. It can present with<br />

severe abdominal pain <strong>of</strong>ten mimicking acute appendicitis. We present an unusual case <strong>of</strong> Yersinia<br />

Enterocolitica mimicking acute cholecystitis.<br />

CASE PRESENTATION: A 27 year old female with history <strong>of</strong> irritable bowel syndrome presented with<br />

eight days <strong>of</strong> severe abdominal pain and diarrhea. The diarrhea was described as having 8-10 watery,<br />

non-bloody, non-mucous bowel movements. She also had a fever <strong>of</strong> 102 degrees F with reported<br />

chills. The abdominal pain was across her upper abdomen. She did report some nausea, but no<br />

vomiting. She had no sick contacts. Given her history, stool was sent for polymerase chain reaction<br />

(PCR) <strong>of</strong> enteric pathogens and CT abdomen was obtained. CT demonstrated marked edematous<br />

changes within the wall <strong>of</strong> the gallbladder and edematous changes within the terminal ileum and right<br />

colon. Laboratory testing revealed an AST <strong>of</strong> 81 U/L (normal: 8-48), ALT <strong>of</strong> 125 U/L (normal: 7-55) and<br />

Alkaline Phosphatase <strong>of</strong> 228 U/L (normal: 24-336).<br />

The patient was admitted to the hospital for further management. An abdominal ultrasound was done<br />

that showed diffuse marked gallbladder wall thickening measuring 13 mm. The gallbladder lumen was<br />

contracted; no cholelithiasis or pericholecystic fluid was present. Patient had a negative sonographic<br />

Murphy's sign. Surgery was consulted for consideration <strong>of</strong> cholecystectomy for acute acalculous<br />

cholecystitis. However, on hospital day 2 her stool studies revealed positive PCR Yersinia<br />

Enterocolitica. She was started on lev<strong>of</strong>loxacin and metronidazole. Her abdominal pain and diarrhea<br />

improved and she was discharged on hospital day 4. She was continued on lev<strong>of</strong>loxacin for a total <strong>of</strong> 14<br />

days. Follow-up abdominal ultrasound at two weeks showed complete resolution <strong>of</strong> the gallbladder wall<br />

thickening; the gallbladder wall measured 1.6 mm, decreased from 13 mm on prior US. She had<br />

complete resolution <strong>of</strong> abdominal pain and diarrhea.<br />

DISCUSSION: Yersinia Enterocolitica is classically known to cause ileocolitis, <strong>of</strong>ten mimicking Crohn’s<br />

disease or acute appendicitis. However, acute cholecystitis in the setting <strong>of</strong> acute ileocolitis, should alert<br />

to possible infectious etiologies such as Yersinia enterocolitis. Stool PCR might <strong>of</strong>fer higher sensitivity<br />

and have a faster turn around in the work-up for acute ileocolitis compared to stool cultures.<br />

Potential association <strong>of</strong> pathogenicity with a previously reported low-density lipoprotein receptor<br />

polymorphism in individuals <strong>of</strong> African descent<br />

Darrell B Newman, MD Second Author: Suraj Kapa, MD Third Author: Gautam Kumar, MBBS Fourth<br />

Author: Richard M Elias, MBBS<br />

INTRODUCTION: Several hundred low density lipoprotein receptor (LDLR) mutations have been<br />

identified and characterized in specific populations (2). We present a case <strong>of</strong> premature acute coronary<br />

syndrome <strong>of</strong> in a patient <strong>of</strong> African descent involving a rare mutation in the EGF-like calcium binding<br />

domain <strong>of</strong> the LDLR that, to our knowledge, has not previously been associated with pathogenicity.<br />

CASE PRESENTATION: A 23-year-old Somali male with no significant past medical history presented to<br />

an outside hospital with severe, substernal chest pain <strong>of</strong> 2 hours duration. An EKG at that time showed<br />

2-3 mm ST elevation in leads II, III, and aVF. Laboratory studies were remarkable for a Troponin T <strong>of</strong> 2.79<br />

ng/mL (normal < 0.03 ng/mL). He was immediately transferred to our hospital by ground ambulance<br />

where he underwent percutaneous coronary intervention (PCI) <strong>of</strong> a ST-elevation myocardial infarction<br />

(STEMI). Cardiac catheterization revealed complete occlusion <strong>of</strong> the proximal right coronary artery and,<br />

following revascularization, he underwent successful deployment <strong>of</strong> a drug-eluting stent in the right<br />

coronary artery. Subsequent laboratory analysis revealed a total cholesterol <strong>of</strong> 278 mg/dL (normal < 200<br />

mg/dL) , LDL <strong>of</strong> 226 mg/dL (normal < 100 mg/dL), and HDL <strong>of</strong> 39 mg/dL (normal range > 40 mg/dL).<br />

Homocysteine, Lipoprotein (a), and high sensitivity C-reactive protein levels were within established cut<strong>of</strong>f<br />

values. The patient did not use nicotine or ethanol. On physical exam, there were no outward signs<br />

<strong>of</strong> hypercholesterolemia. On further review, he was unaware <strong>of</strong> any history <strong>of</strong> cardiac events in the<br />

immediate family.<br />

Genetic testing revealed a variant <strong>of</strong> likely pathogenicity at Exon 8, Nucleotide 1145 (1145G>T) <strong>of</strong> the<br />

LDLR resulting in a missense mutation (G382V) in the EGF-like 2 potential calcium-binding<br />

domain. There is a moderate stereochemical difference between Glycine and Valine and this mutation<br />

should not be tolerated according to Poly Phen or SIFT prediction models (3, 4). The results <strong>of</strong> MLPA did<br />

not reveal a large genomic deletion or duplication in the LDLR gene, further supporting a disease-causing<br />

role <strong>of</strong> the identified mutation. APOB genotyping was not performed given the African ethnicity <strong>of</strong> this<br />

patient.<br />

DISCUSSION: The novel mutation described herein is potentially pathogenic and thus, may be<br />

consistent with a diagnosis <strong>of</strong> familial hypercholesterolemia. This variant has not previously been<br />

reported as a known deleterious mutation in publicly available gene compendiums. Therefore, we<br />

believe this to be a novel, potentially pathogenic mutation in the LDLR gene and recommend that<br />

screening, in particular <strong>of</strong> patients <strong>of</strong> African-descent, should include notation <strong>of</strong> this specific variant.<br />

A Diagnosis Caught "Red-Handed"<br />

Sandeep M. Patel, MD, Katie M. Rieck, MD, Aurelia A. Smith, MD, Raghuwansh P. Sah, MD, M. Caroline<br />

Burton, MD<br />

INTRODUCTION: Dermatologic manifestations may be the first sign <strong>of</strong> an underlying systemic<br />

disorder. However, if the “rash” is not obvious, a massive work-up may ensue delaying therapeutic<br />

intervention. We present an interesting case <strong>of</strong> “red hands” that ultimately guided us towards the<br />

correct diagnosis.<br />

CASE PRESENTATION: A 74-year-old male without past history presented for second evaluation <strong>of</strong><br />

hand pain. The pain began 2 months ago and was gradual in onset. He described the pain as “being on<br />

fire” involving mainly the palms <strong>of</strong> both hands. He revealed that the pain improved with elevation and<br />

ice but worsened when his hands were at his sides. Concomitantly, he noted that his hands were more<br />

reddish-purple in color. On review <strong>of</strong> systems, the patient noted fatigue and occasional night sweats.<br />

Notable exam findings included a cachectic-looking Caucasian male in no distress. Abdominal<br />

distension was noted with dullness to percussion 6 cm below the right costal margin and a palpable<br />

spleen tip 4 cm to the left <strong>of</strong> the umbilicus. Dermatologic exam demonstrated erythematousviolaceous,<br />

diffusely tender palms that were warm to touch with slight moistness. With elevation above<br />

his head, there was improvement <strong>of</strong> the pain and central pallor <strong>of</strong> his palms within 30 seconds; with<br />

dependency the initial findings returned. Radial and ulnar pulses were intact bilaterally. The rest <strong>of</strong> the<br />

exam was unremarkable.<br />

At our institution, initial complete blood count with differential was notable for WBC 18.0 x 10(9)/L (83<br />

% Neutrophils, Lymphocytes 7%, Monocytes 1%, Eosinophils 1%, Basophils 5%, Metamyelocytes 2%,<br />

Myelocytes 2%), Hemoglobin 13.5 g/dL, Platelets 309 x 10(9) g/dL, and normal electrolytes and liver<br />

function. A peripheral smear demonstrated toxic changes and Dohle bodies. Erythrocyte sedimentation<br />

rate and c-reactive protein were minimally elevated. Serum and urine protein electrophoresis with<br />

immun<strong>of</strong>ixation were unremarkable. Anti-nuclear and anti-neutrophilic cytoplasmic antibodies were<br />

negative. Computed tomography <strong>of</strong> the abdomen demonstrated hepatosplenomegaly without<br />

ascites. Review <strong>of</strong> an outside bone marrow biopsy demonstrated no notable findings.<br />

The dermatologic changes were consistent with erythromelalgia. Given the constellation <strong>of</strong> findings, a<br />

hematologic disorder was suspected. The patient underwent a second bone marrow biopsy which<br />

demonstrated a myeloproliferative neoplasm consistent with primary myel<strong>of</strong>ibrosis with JAK 2 V617F<br />

positivity. The patient was initiated on aspirin and is currently undergoing evaluation for trials involving<br />

JAK 2 inhibitors.<br />

DISCUSSION: Erythromelalgia is a rare functional vascular disorder <strong>of</strong> the extremities characterized by<br />

paroxysmal, bilateral, symmetric episodes <strong>of</strong> burning, erythema, pain, and occasional swelling, with a<br />

local elevation in temperature that is exacerbated by dependency or heat and alleviated by elevation or<br />

cool temperatures. The diagnosis is clinical and treatment with aspirin may result in improvement. As a<br />

majority <strong>of</strong> cases are secondary, if erythromelalgia is suspected, patients should be evaluated for<br />

underlying ailments, especially hematologic disorders.<br />

A "Sluggish" Case <strong>of</strong> Renal Failure<br />

Sandeep M. Patel, MD and Suzanne M. Norby MD<br />

INTRODUCTION: Renal failure and hypothyroidism are common problems in hospitalized<br />

patients. Usually presenting separately, the occurrence <strong>of</strong> one does not affect the other. However, the<br />

potential relationship is underappreciated, requiring a high index <strong>of</strong> suspicion to diagnose this rare but<br />

reversible cause <strong>of</strong> kidney disease.<br />

CASE PRESENTATION: A 68-year-old male with a history <strong>of</strong> hypertension treated with lisinopril<br />

presented with worsening fatigue, confusion, and gait imbalance. His wife noted that his voice had<br />

become deeper and his speech much more slowed.<br />

On physical exam, temperature was 36.1 C, blood pressure 144/88 mmHg, and pulse 52 beats per<br />

minute. His mentation was sluggish; speech was slow, and voice was deep. Alopecia and periorbital<br />

edema were present. Skin was, paper-thin, pr<strong>of</strong>oundly dry, and cracked as well as sallow and yellowish<br />

in color. The thyroid was firm and nontender with mild symmetrical enlargement without<br />

nodules. There was non-pitting edema <strong>of</strong> both lower extremities. The proximal musculature <strong>of</strong> all four<br />

limbs was atrophic. Peripheral deep tendon reflexes were decreased. The remainder <strong>of</strong> the exam was<br />

unremarkable.<br />

Laboratory studies revealed hyponatremia (133 meq/L [135-145]), hypercalcemia (ionized level 6.21<br />

mg/dL [4.8-5.7]), normocytic anemia (hemoglobin 10.4 g/dL) and serum creatinine level <strong>of</strong> 2.4 mg/dL<br />

(0.8-1.3) [baseline 8 months ago 1.5 mg/dl ] with blood urea nitrogen level 33 mg/dL (8-23). Urinalysis<br />

with microscopy was normal. Renal ultrasound with Doppler imaging revealed increased cortical<br />

echogenicity bilaterally with patent renal arteries and veins. In lieu <strong>of</strong> the physical findings, the thyroid<br />

gland was evaluated. Thyroid-stimulating hormone level was 94.1 mIU/L (0.3-5.0), and T3 and T4 levels<br />

were undetectable. Thyroid peroxidase antibody level was > 950 IU/mL ( 500 IU/mL (

Forgotten Sequelae<br />

Chaithra Prasad, MD, Bharath Palraj, MD<br />

INTRODUCTION:Infliximab is a monoclonal anti-tumor necrosis factor alpha antibody used increasingly<br />

frequently in the management <strong>of</strong> inflammatory bowel disease and rheumatoid arthritis. Infliximab<br />

therapy has been associated with serious infections including disseminated tuberculosis (TB), invasive<br />

fungal infections and bacterial infections like Listeria and Legionella. Active cases <strong>of</strong> TB can include<br />

reactivation <strong>of</strong> latent TB and less frequently, primary TB. This case highlights the importance <strong>of</strong> (1)<br />

screening for TB prior to initiation <strong>of</strong> infliximab and (2) considering TB in the differential diagnosis <strong>of</strong><br />

lung infiltrates in patients on infliximab.<br />

CASE PRESENTATION: An 18-year-old female high school student from Iowa with a 3-year history <strong>of</strong><br />

ulcerative colitis on infliximab therapy initially presented to her primary care physician with severe<br />

cough, dyspnea, fever, and worsening abdominal pain. Details <strong>of</strong> the outside physical examination<br />

findings are unavailable but we know a CT-abdomen that captured the lung bases was performed,<br />

revealing nodular bibasilar lung infiltrates and no intra-abdominal pathology. She was prescribed a 2week<br />

course <strong>of</strong> cipr<strong>of</strong>loxacin, amoxicillin, clarithromycin, and prednisone. She improved to the point<br />

that she could resume classes and her part-time job at a pizza joint. However, her symptoms recurred<br />

within a week <strong>of</strong> having discontinued her antimicrobial regimen and she presented for reevaluation.<br />

Physical examination revealed a febrile and tachypneic thin Caucasian female with diffusely<br />

coarse breath sounds and notably bronchial breath sounds in the left upper lung field. WBC count was<br />

3500/mL. CT-chest showed diffuse miliary nodular lung infiltrates with a focal area <strong>of</strong> consolidation in<br />

the left upper lung extending to the hilum and bilateral hilar adenopathy. CT-abdomen showed ascites<br />

with peritoneal and splenic nodules. Bronchoalveolar lavage smear was positive for acid-fast bacilli and<br />

culture grew Mycobacterium TB sensitive to all 4 first-line drugs. She had traveled only within the<br />

United States and had no history <strong>of</strong> incarceration or known TB exposure. She was unsure whether she<br />

had received TB screening prior to infliximab initiation. After 9 months <strong>of</strong> the anti-TB regimen, the<br />

patient’s cough, fever, dyspnea, and abdominal pain had resolved and repeat imaging showed complete<br />

resolution <strong>of</strong> the pulmonary infiltrates, adenopathy, as well as the peritoneal and splenic nodules.<br />

DISCUSSION: Internists are likely to see the forgotten sequelae <strong>of</strong> medications initiated by<br />

subspecialists. Biologicals targeting different arms <strong>of</strong> the immune system are being widely used in<br />

various inflammatory conditions. Either reactivation or primary TB can develop after the initiation <strong>of</strong><br />

infliximab and can result in disseminated military TB. This case highlights the importance <strong>of</strong> TB<br />

screening before starting infliximab as well as the importance <strong>of</strong> considering TB in the differential<br />

diagnosis <strong>of</strong> lung infiltrates in the infliximab-treated patient.<br />

Methotrexate Toxicity: When The Treatment Is Worse Than The Disease<br />

David Raslau, MD<br />

INTRODUCTION:Methotrexate is routinely used in the management <strong>of</strong> leukemias and lymphomas. It’s<br />

wide spread use has revealed rare complications that were not previously known, specifically that some<br />

patients can develop very high concentrations <strong>of</strong> methotrexate from either peripheral or intrathecal use<br />

which can sometimes lead to encephalopathy. Most cases are benign and resolve on their own, but<br />

there are reports <strong>of</strong> fatalities as well. This case highlights an episode <strong>of</strong> methotrexate-induced<br />

encephalopathy that was prolonged and required further intervention.<br />

CASE PRESENTATION: A 53 year old male who was recently diagnosed with large B cell lymphoma was<br />

admitted to the hospital for high-dose methotrexate as part <strong>of</strong> cycle #1 <strong>of</strong> CODOX-M. He received his<br />

medications per protocol and urine alkalinization and leucovorin rescue were started, again per<br />

protocol. However, his 48-hour methotrexate level was extremely elevated at 118.75 mcmol/L. He also<br />

started to develop signs <strong>of</strong> encephalopathy consisting <strong>of</strong> altered mental status with confusion,<br />

disorientation, visual and auditory hallucinations, dysarthria, expressive aphasia, and pathological<br />

reflexes which were suggestive <strong>of</strong> methotrexate-induced encephalopathy. A head CT was obtained<br />

which was normal. He was transferred to an intensive care unit where he was started on continuous<br />

renal replacement therapy until his methotrexate level was reduced to 1.44 mcmol/L.<br />

Because <strong>of</strong> this episode he also developed acute renal failure with his creatinine increasing from a<br />

baseline <strong>of</strong> 0.6 mg/dL to 2.8 mg/dL. His renal function stabilized but did not fully recover during the rest<br />

<strong>of</strong> his hospitalization. On dismissal from the hospital, his creatinine remained elevated at 2.3 mg/dL.<br />

He was transferred back to the floor where rescue measure with urine alkalinization and leucovorin<br />

were continued. However, he was not making much progress. We decided to try treating with<br />

dextromethorphan as there has been some discussion about its potential benefit in the situation and<br />

even some literature regarding its use. He was started on dextromethorphan and within 24 hours his<br />

encephalitis started to improve. By 72 hours, his symptoms had almost completely resolved. During this<br />

time, his creatinine only mildly improved from a level <strong>of</strong> 2.8 to 2.5 mg/dL. His methotrexate level finally<br />

returned < 0.1 mcmol/L and he was dismissed from the hospital. Over the next several weeks, his<br />

mental status and renal function returned fully to baseline.<br />

DISCUSSION: This highlights one <strong>of</strong> the rare but severe side effects <strong>of</strong> methotrexate. It also seems to<br />

suggest that dextromethorphan can be used to aid in combating methotrexate-induced encephalopathy<br />

as there were no other treatments giving during the time <strong>of</strong> his clinical improvement and his renal<br />

function did not improve significantly. An argument can be made that he should have remained on<br />

continuous renal replacement therapy until the methotrexate was fully cleared. This may have been<br />

beneficial in this patient. Further studies will be needed to determine the pathogenesis <strong>of</strong><br />

methotrexate-induced encephalopathy as well as the role <strong>of</strong> continuous renal replacement therapy and<br />

dextromethorphan in cases <strong>of</strong> methotrexate-induced encephalopathy.<br />

Shortness <strong>of</strong> Breath and Fatigue: Common Symptoms with an Uncommon Culprit<br />

John T Ratelle, MD Additional authors: Mark Wieland, M.D. Andre C. Lapeyre, III, M.D.<br />

INTRODUCTION: CASE PRESENTATION: A 57 year-old female presented to clinic with a two week<br />

history <strong>of</strong> fatigue and shortness <strong>of</strong> breath. Review <strong>of</strong> systems was positive for orthopnea. She denied<br />

chest pain, cough, edema, fevers, chills, or weight loss. Her past medical history was significant for<br />

hemoglobinopathy E and Tak mutation manifesting as a stable, asymptomatic erythrocytosis, as well as<br />

depression. Her only medication was paroxetine 10 mg daily. Vital signs were normal. Cardiac<br />

auscultation revealed a 1/6 diastolic murmur. There was no jugular venous distension or peripheral<br />

edema. Lungs were clear. The remainder <strong>of</strong> the physical examination was unremarkable. Laboratory<br />

evaluation, including CBC, TSH, and electrolytes, were normal or unchanged. Chest x-ray was remarkable<br />

for cardiomegaly with mild interstitial edema. Electrocardiogram showed evidence <strong>of</strong> left atrial<br />

enlargement. Based on these findings and progressive symptoms, an echocardiogram was performed<br />

which revealed a left atrial mass attached to the superior aspect <strong>of</strong> the interatrial septum measuring<br />

5.82 x 3.46 cm with associated mitral obstruction during diastole. Her right ventricular systolic pressure<br />

was elevated at 52 mmHg; left ventricular ejection fraction was normal. The patient was referred to<br />

cardiology and cardiovascular surgery. She underwent subsequent excision <strong>of</strong> the left atrial tumor;<br />

pathology revealed a myxoma. Her hospital course was uneventful and she was discharged on hospital<br />

day #5. The patient’s symptoms resolved after surgery.<br />

DISCUSSION: Myxomas are the most common primary cardiac neoplasm, but remain rare with an<br />

incidence <strong>of</strong> 0.5 per million. Most myxomas (75%) occur in the left atria and physical examination may<br />

reveal a mid diastolic murmur and a classic mid-diastolic “tumor plop"1-3. Cardiovascular symptoms<br />

(cough, shortness <strong>of</strong> breath, syncope) are the most common on presentation, found in up to 70% <strong>of</strong><br />

patients. Constitutional symptoms may also be present in a third <strong>of</strong> patients that are thought to be<br />

secondary to release <strong>of</strong> inflammatory cytokines from the tumor. Systemic embolization may be present<br />

in one third <strong>of</strong> patients on presentation4. Once the diagnosis <strong>of</strong> myxoma has been made, treatment<br />

consists <strong>of</strong> prompt surgical resection because <strong>of</strong> the risk for systemic embolization as well as sudden<br />

death3,4. Surgical outcomes are generally good and most patients achieve resolution <strong>of</strong> her symptoms.<br />

Myxomas may recur in 5-10% <strong>of</strong> cases1,4. In conclusion, myxomas are a rare entity that can present<br />

with common <strong>of</strong>fice complaints including fatigue, shortness <strong>of</strong> breath and weight loss.<br />

A case <strong>of</strong> fever <strong>of</strong> not-so-unknown origin<br />

Julio C Sartori-Valinotti, MD Lia C. Kaufman, MD M. Rizwan Sohail, MD<br />

INTRODUCTION: Deciphering the enigma <strong>of</strong> fever <strong>of</strong> unknown origin (FUO) can be rewarding if the<br />

diagnosis can be made in a timely manner to allow appropriate treatment. Unfortunately, despite<br />

important advances in diagnostic techniques, working up FUO remains a difficult task.<br />

CASE PRESENTATION: A 49-year-old previously healthy man presented to his local hospital with a 3day<br />

history <strong>of</strong> malaise and low-grade fevers. He was treated with azithromycin for presumed sinusitis<br />

and dismissed. However, symptoms persisted, prompting a second visit where he was prescribed<br />

doxycycline for suspected tick-borne illness. Unfortunately, his condition worsened, and so he sought<br />

care at another institution, where he was found to be pancytopenic, instigating admission and empiric<br />

broad spectrum anti-bacterial and antifungals therapy. An extensive work-up for infectious diseases was<br />

initiated, including bacterial, fungal and mycobacterial blood cultures, viral and fungal serologies, and<br />

CSF analyses that were all unremarkable. Labs were significant for an elevated ferritin at 3356 ug/L<br />

(normal 11-307 ug/L), and liver transaminases that were 5 times the upper limits <strong>of</strong> normal. CT <strong>of</strong> the<br />

abdomen revealed splenomegaly. Bone marrow biopsy (BMB) demonstrated features <strong>of</strong> myelodysplastic<br />

syndrome and filamentous organisms. The diagnosis <strong>of</strong> hemophagocytic lymphohistiocytosis (HLH) was<br />

made and patient was started on cyclosporine, methylprednisolone and rituximab. In spite <strong>of</strong> this, his<br />

fevers persisted. The filamentous forms seen on the BMB were felt to be contaminants and antifungals<br />

were discontinued. After 21 days <strong>of</strong> hospitalization without any clinical improvement, the patient was<br />

transferred to our institution for further evaluation, where he was kept on vancomycin and imipenem.<br />

Repeat BMB showed hypocellular marrow with necrosis and hemophagocytosis. GMS stain suggested<br />

mycobacterial or Nocardia infection. Liver biopsy revealed occasional thin AFB within histiocytes. On<br />

hospital day 5, outside blood cultures obtained prior to transfer grew AFB, which tested negative for<br />

Mycobacterium avium complex. Antibiotics were switched to imipenem and azithromycin for atypical<br />

mycobacterial coverage, and trimethoprim-sulfamethoxazole was subsequently added to cover<br />

possibility <strong>of</strong> nocardia. On day 8, the patient became hemodynamically unstable and emergent<br />

echocardiogram revealed a mobile thrombus in the right atrium. The patient died later that day. A few<br />

hours later, blood cultures from outside hospital and our institution were reported to grow<br />

Mycobacterium kansasii. Autopsy revealed systemic granulomatosis, involving spleen, brain,<br />

thoracoabdominal lymph nodes, liver, bone marrow, and lungs positive for AFB.<br />

DISCUSSION: HLH is a rare and <strong>of</strong>ten fatal condition characterized by immune dysregulation and nonspecific<br />

activation <strong>of</strong> macrophages resulting in phagocytosis <strong>of</strong> erythrocytes, leukocytes, platelets and<br />

their precursors. It can present as a primary process due to a genetic defect, or secondary to infections<br />

(most commonly EBV), or autoimmune disorders. Mycobacteria-driven HLH is an unusual entity rarely<br />

reported in the literature. However, it is an important diagnosis to consider when evaluating a case <strong>of</strong><br />

FUO.<br />

A case <strong>of</strong> cryptogenic hemoptysis, deciphered.<br />

Julio C Sartori-Valinotti, MD Charles F. Thomas, MD<br />

INTRODUCTION: Reaching an ultimate diagnosis for intermittent hemoptysis can be both challenging<br />

and frustrating. Indeed, in spite <strong>of</strong> extensive evaluation including repeated use <strong>of</strong> bronchoscopy, the<br />

precise etiology remains unclear in 25 to 30% <strong>of</strong> patients.<br />

CASE PRESENTATION: A 75-year-old man presented to the pulmonary clinic for a second opinion<br />

regarding one-year history <strong>of</strong> intermittent hemoptysis, cough and unintentional weight loss. His past<br />

medical history was significant for squamous cell lung carcinoma s/p left pneumonectomy and<br />

chemotherapy five years prior. He had undergone extensive evaluation at an outside facility. CT <strong>of</strong><br />

chest/abdomen/pelvis showed changes consistent with left-sided pneumonectomy but no mediastinal,<br />

hilar or axillary lymphadenopathy or pleural pathology. Outside bronchoscopy indicated small amount <strong>of</strong><br />

blood coming from the left endobronchial stump but no evidence <strong>of</strong> tumor hence no biopsies were<br />

obtained and no interventions were undertaken. Repeat CT five months later demonstrated interval<br />

development <strong>of</strong> mediastinal lymphadenopathy, areas <strong>of</strong> attenuation within the liver and spleen, and<br />

small amount <strong>of</strong> fluid or s<strong>of</strong>t tissue with displacement <strong>of</strong> the mediastinum to the left. These findings<br />

prompted biopsy <strong>of</strong> the lung, lymph nodes, stomach, liver and spleen. The latter was complicated with<br />

chest wall MRSA abscess which was drained and treated with antibiotics. All biopsies were negative for<br />

malignancy. At our institution we proceeded with PET scan that demonstrated hypermetabolic masses<br />

along the left pleural surface with an SUV max <strong>of</strong> 9.5 (Figure 1), hypermetabolic s<strong>of</strong>t tissue mass in the<br />

left chest wall corresponding to prior abscess and diffuse bone marrow hypermetabolism possibly<br />

induced by severe infection. MRI <strong>of</strong> the brain did not suggest brain metastasis. Bronchoscopy revealed a<br />

diffuse mucosal lesion in the distal trachea and left pneumonectomy stump (Figure 2) along with a<br />

defect in the left pneumonectomy stump compatible with bronchopleural fistula (BPF). Multiple biopsies<br />

<strong>of</strong> the diffuse mucosal lesion revealed squamous metaplasia and inflammation without evidence <strong>of</strong><br />

tumor. Similarly, the BAL cytology was negative for malignancy. The patient underwent thoracotomy for<br />

empyema debridement, muscle flap closure <strong>of</strong> the BPF, and Clagget procedure.<br />

DISCUSSION: Although pneumonectomy remains the most common cause <strong>of</strong> BPF, the diagnosis can be<br />

easily missed, particularly in the setting <strong>of</strong> misleading symptoms or imaging findings. Bronchoscopic<br />

saline instillation against the stump is a simple method to test the stump integrity. A high level <strong>of</strong><br />

suspicion is needed to avoid delay treatment and complications.<br />

Erdheim-Chester Disease with Right Atrial Pseudotumor and Temporal Arteritis<br />

Joseph H Skalski, MD William D. Edwards, M.D. Eric L. Matteson, MD, MPH<br />

INTRODUCTION:A 71 year-old man presented with three months <strong>of</strong> severe headache, dyspnea on<br />

exertion, fever, and unintentional weight loss <strong>of</strong> approximately 30kg. His past medical history included<br />

well-controlled diabetes mellitus type 2, hypertension, hyperlipidemia, and end stage renal disease on<br />

hemodialysis. His end stage renal disease had developed over the previous year and had been attributed<br />

to diabetes without confirmation by renal biopsy.<br />

CASE PRESENTATION: A 71 year-old man presented with three months <strong>of</strong> severe headache, dyspnea<br />

on exertion, fever, and unintentional weight loss <strong>of</strong> approximately 30kg. His past medical history<br />

included well-controlled diabetes mellitus type 2, hypertension, hyperlipidemia, and end stage renal<br />

disease on hemodialysis. His end stage renal disease had developed over the previous year and had<br />

been attributed to diabetes without confirmation by renal biopsy. He otherwise had minimal medical<br />

history and prior to this illness was active, vigorous, and independent.<br />

The patient was initially hospitalized for four weeks at another institution where the dyspnea was found<br />

to be due to bilateral pleural effusions. Analysis <strong>of</strong> pleural fluid was nondiagnostic. Head magnetic<br />

resonance imaging (MRI) and cerebral spinal fluid analysis were unrevealing. Temporal artery biopsy<br />

was performed to further evaluate the headache demonstrating an inflammatory arteritis. He later<br />

developed tachy- and brady- arrhythmias and sustained an asystolic cardiac arrest. He was successfully<br />

resuscitated and transferred to our institution. Upon arrival, his primary symptom was a severe<br />

headache. Physical examination was unremarkable. Laboratory testing demonstrated markedly<br />

elevated C-reactive protein at 192.7 mg/L. The remainder <strong>of</strong> the laboratory testing was unrevealing<br />

including negative vasculitis and auto-antibody screening. Cardiac MRI demonstrated an infiltrating<br />

right atrial mass as the probable cause <strong>of</strong> his arrhythmia. Percutaneous biopsy <strong>of</strong> the right atrial mass<br />

demonstrated a foamy histiocytic infiltrate that stained positive for CD68 and negative for S100. A<br />

diagnosis <strong>of</strong> Erdheim-Chester disease was made. The temporal artery biopsy slides were re-reviewed in<br />

light <strong>of</strong> this diagnosis, and the arterial infiltrate was observed to be a CD68+ histocytic infiltrate<br />

consistent with Erdheim-Chester disease. There is no standardized treatment for Erdheim-Chester<br />

disease. In consultation with hematology, treatment was initiated with anakinra, an IL-1<br />

antagonist. With treatment, our patient experienced significant improvement, including resolution <strong>of</strong><br />

headache. C-reactive protein was undetectable at

An unusual presentation <strong>of</strong> Henoch Schönlein Purpura in an elderly female<br />

Eoin R Storan, MBChB Co-Authors: Miguel Lalama MD Nandakumar Srinivasan MD Robert Kraichely MD<br />

INTRODUCTION: Henoch Schönlein Purpura (HSP) is a form <strong>of</strong> systemic vasculitis which is most<br />

commonly seen in children. It most frequently presents with the classical tetrad <strong>of</strong> a palpable purpuric<br />

rash, arthralgia or arthritis, abdominal pain and renal disease. Adult patients with HSP present in a<br />

similar fashion to children, and renal disease is particularly common in affected adult patients.<br />

CASE PRESENTATION: A 71-year-old woman was admitted to hospital for evaluation <strong>of</strong> a one-month<br />

history <strong>of</strong> nausea, anorexia, abdominal pain and increasing abdominal distention. Her physical<br />

examination revealed a distended abdomen with tenderness in the epigastrium and the left lower<br />

quadrant. There was dullness to percussion at the flanks consistent with ascites. The remainder <strong>of</strong> her<br />

physical examination was within normal limits. Laboratory studies <strong>of</strong> note included a mild normocytic<br />

anemia. Serum creatinine was within normal range and urinalysis was bland. The remainders <strong>of</strong> her<br />

laboratory studies were within normal ranges. Autoimmune serological testing and celiac panel were<br />

negative. Infectious work-up including stool studies with culture and Clostridium difficile toxin; blood<br />

and urine cultures were negative.<br />

CT <strong>of</strong> abdomen and pelvis showed free intraperitoneal fluid, thickening <strong>of</strong> the prepyloric region <strong>of</strong> the<br />

stomach, the entire duodenum and proximal jejunum through to the ascending colon. CT angiography <strong>of</strong><br />

the abdominal vessels was normal. She underwent an ultrasound-guided large-volume paracentesis and<br />

fluid analysis was negative for infection and malignancy. Esophagogastroduodenoscopy (EGD) showed<br />

multiple esophageal and duodenal ulcerations. Biopsies were taken and showed non-specific<br />

inflammation with negative cytomegalovirus (CMV) and Helicobacter pylori staining. She proceeded to<br />

colonoscopy that revealed acute proctosigmoiditis. Colonic biopsies were taken and revealed mild active<br />

colitis without specific features, with negative staining for CMV. One week after hospitalization she<br />

developed a palpable purpuric rash on her upper and lower extremities, abdomen and trunk. A skin<br />

biopsy was taken <strong>of</strong> her rash. This revealed superficial blood vessels, which stained positive for IgA<br />

under direct immun<strong>of</strong>luorescence consistent with IgA-mediated vasculitis. She was diagnosed with Adult<br />

HSP.<br />

She received 3 days <strong>of</strong> parenteral methylprednisolone pulse therapy and her rash and abdominal pain<br />

markedly improved. She was transitioned to high dose oral prednisone daily and she continued to<br />

improve with resolution <strong>of</strong> her rash after 7 days. She was maintained on a slow tapering dose <strong>of</strong> oral<br />

prednisone therapy.<br />

DISCUSSION: This case posed a diagnostic challenge due to the initial absence <strong>of</strong> the characteristic<br />

rash, the presence <strong>of</strong> ascites and the lack <strong>of</strong> renal involvement. Together with this patient’s advanced<br />

aged, this heralded a low level <strong>of</strong> suspicion for an IgA-mediated vasculitis. This case highlights that HSP<br />

can occur in the elderly population and may present in an atypical fashion.<br />

Perilous Purpura: An Unusual Presentation <strong>of</strong> Renal Cell Carcinoma<br />

Karna K Sundsted, MD, Jason Szostek, M.D.<br />

INTRODUCTION: Henoch-Schönlein purpura (HSP) is a small vessel vasculitis that is characterized by<br />

arthralgias, palpable purpura, abdominal pain and glomerulonephritis. It rarely occurs in adults. In<br />

approximately 60% <strong>of</strong> adult cases, it is a manifestation <strong>of</strong> a solid tumor malignancy, suggesting clinicians<br />

should consider occult neoplasm in adults who present with HSP.<br />

CASE PRESENTATION: A 47-year-old man with a history <strong>of</strong> infectious eczematoid dermatitis was<br />

admitted to the inpatient medicine service with a painful, progressive rash and disabling<br />

polyarthritis. Since the onset <strong>of</strong> the rash two weeks prior, the patient was evaluated twice by<br />

dermatology who ultimately diagnosed him with HSP based on clinical exam, otherwise normal<br />

laboratory testing and punch biopsies showing leukocytoclastic vasculitis with weakly positive IgA. As an<br />

outpatient, he was started on dapsone and topical treatments. At the time <strong>of</strong> hospitalization, the<br />

patient reported progression <strong>of</strong> his rash and polyarthritis along with two recent episodes <strong>of</strong> severe<br />

abdominal pain. He denied other symptoms or recent medication changes. On exam, the patient had<br />

diffuse palpable purpura with ulcerations. Within 24 hours <strong>of</strong> hospitalization, the patient developed a<br />

markedly edematous uvula manifesting as cough and sore throat. Oral prednisone 60 milligrams daily<br />

was initiated along with ongoing use <strong>of</strong> wet dressings, topical steroids and dapsone. A chest radiograph<br />

was negative, but computed topography <strong>of</strong> his abdomen showed a 1.6 centimeter solid right kidney<br />

mass. He underwent a right partial curative nephrectomy with pathology revealing clear cell renal<br />

carcinoma (RCC) and IgA nephropathy, in the setting <strong>of</strong> a normal creatinine and urinalysis. At the time<br />

<strong>of</strong> three month follow-up, the patient’s rash and arthralgias had resolved without ongoing treatment,<br />

and he has had no subsequent recurrence.<br />

DISCUSSION: We report the case <strong>of</strong> an adult who was diagnosed with RCC in association with HSP. HSP<br />

is a systemic vasculitis, resulting in the tissue deposition <strong>of</strong> IgA-containing immune<br />

complexes. According to the <strong>American</strong> <strong>College</strong> <strong>of</strong> Rheumatology, the diagnosis <strong>of</strong> HSP requires at least<br />

two <strong>of</strong> four criteria including palpable purpura, age less than 20, bowel angina and wall granulocytes on<br />

biopsy. Although considered mainly a disease <strong>of</strong> children, it can rarely occur in adults. As <strong>of</strong> 2006, 31<br />

cases <strong>of</strong> adult malignancy-associated HSP have been reported, predominantly solid tumors, with nonsmall<br />

cell lung cancer most common. Of adult cases <strong>of</strong> HSP-associated solid tumor malignancy, RCC is<br />

rare. Most frequently, HSP occurs within one month <strong>of</strong> the cancer diagnosis. The pathophysiology <strong>of</strong><br />

HSP in association with malignancy is not well understood, but it has been hypothesized that tumor<br />

neoantigens may play a role. In most cases, HSP resolves after successful treatment <strong>of</strong> the associated<br />

malignancy, as was the case in our patient.<br />

Superwarfarin poisoning: a challenging coagulopathy<br />

Hemang Yadav, MBBS Second Author: Dr C Christopher Hook, MD<br />

INTRODUCTION: Superwarfarins are warfarin-like compounds that are markedly more potent and<br />

lipophilic than warfarin itself. Superwarfarins are widely used as rodenticide. Poisoning, resulting in a<br />

hemorrhagic coagulopathy, is increasingly seen. Not recognized unless clinical suspicion is high,<br />

superwarfarin poisioning can be potentially devastating. We describe a case <strong>of</strong> accidental superwarfarin<br />

ingestion and its challenging management.<br />

CASE PRESENTATION: A previously healthy 40-year-old female presented to an emergency<br />

department with bilateral flank pain, hematuria, frank hematemesis, hemoptysis, epistaxis and gingival<br />

bleeding. Coagulation studies were significant for a prothrombin time (PT) over 130 seconds, INR <strong>of</strong> over<br />

10 and partial thromboplastin time (PTT) <strong>of</strong> 105 seconds. She was anemic, with a hemoglobin <strong>of</strong> 10.7. CT<br />

Abdomen/Pelvis was negative for retroperitoneal bleed. She was given 4 units fresh frozen plasma (FFP),<br />

5 mg vitamin K and transferred to the Mayo Clinic for further evaluation.<br />

Further history was obtained on arrival. She had no history <strong>of</strong> coagulopathy and had prior surgeries<br />

without bleeding complications. She denied significant family history, travel or exposures. Further<br />

testing was performed (Table 1). Platelets, fibrinogen and peripheral smear were normal. Inflammatory<br />

markers were not elevated. Liver function tests, including albumin, were also normal. After initially<br />

improving to 4.1 with FFP, INR rebounded to 7.2. She continued to require daily FFP and vitamin K for<br />

correction. Hematology was consulted.<br />

She had special coagulation testing performed, with PT and aPTT showing significant prolongation,<br />

largely corrected on the mixing studies. Factor studies showed deficiency <strong>of</strong> vitamin K-dependent<br />

factors, including factors II, VII, IX, X. Warfarin level was undetectable. Superwarfarin testing by high<br />

performance liquid chromatography (HPLC) was positive for Brodifacoum. The source <strong>of</strong> the ingestion<br />

remains unclear. Attempted poisoning by ex-boyfriend's ex-girlfriend was suggested but never proven.<br />

She was discharged on oral vitamin K, initially 20 mg every 4 hours but developed nausea and vomiting<br />

with this. With vomiting episodes, her INR would increase, requiring FFP support. She transitioned to<br />

subcutaneous vitamin K injections, 10 mg four times daily. She continues on 3-times weekly lab draws<br />

(Figure 1), with FFP support for markedly elevated INRs. 10 months after diagnosis, her Brodifacoum<br />

levels remain detectable. She has received over 50 units <strong>of</strong> FFP and around 20 g <strong>of</strong> vitamin K over this<br />

time period. She has not had further bleeding episodes.<br />

DISCUSSION: The "superwarfarins" (brodifacoum, coumafuryl, difenacoum, bromadiolone) are<br />

lipophilic, long-acting rodenticides. Potency is approximately 100 times greater than warfarin. Half lives<br />

are between 10 and 69 days, as opposed to 40 hours for Warfarin. Patients present with prolonged<br />

PT/PTT that corrects with mixing studies, and selective deficiency <strong>of</strong> vitamin-K-related factors.<br />

Superwarfarins are widely used as rodenticides throughout the United States and consequently toxicity<br />

may present to the internist through accidental ingestion, particularly in rural areas, intentional<br />

poisoning or intentional self-ingestion. Management is challenging due to the prolonged monitoring and<br />

massive doses <strong>of</strong> vitamin K needed. The clinician needs to include superwarfarin ingestion in the<br />

differential for patients presenting with unexplained coagulopathy (see algorithm, Figure 2). Diagnostic<br />

testing through HPLC or mass spectrometry is available in regional centers.<br />

Chapter Winning Abstract - Double Trouble: Paraneoplastic Hypercalcemia-Hyperleukocytosis Syndrome<br />

In Cutaneous Squamous Cell Carcinoma<br />

INTRODUCTION: Less than thirty cases <strong>of</strong> humoral hypercalcemia <strong>of</strong> malignancy (HHM) secondary to<br />

primary cutaneous squamous cell carcinoma (SCC) have been documented. In only a few <strong>of</strong> these cases<br />

is the hypercalcemia concomitant with hyperleukocytosis, a finding known as hypercalcemiahyperleukocytosis<br />

syndrome. In comparing these instances with those <strong>of</strong> hypercalcemia alone, survival<br />

<strong>of</strong> patients with hypercalcemia-hyperleukocytosis syndrome appears to be shorter.<br />

CASE PRESENTATION: A 54 year-old African-<strong>American</strong> male with recurrent cutaneous abscess<br />

formation at the site <strong>of</strong> a proximal right thigh mass presented with three days <strong>of</strong> altered mental status.<br />

A previous biopsy <strong>of</strong> the mass demonstrated moderately to well-differentiated SCC. On initial<br />

presentation to our hospital he had a serum calcium <strong>of</strong> 15.9 mg/dl and a WBC count <strong>of</strong> 15,800. A CT <strong>of</strong><br />

the head showed multiple low-density lesions suspicious for metastatic disease, and a CT <strong>of</strong> the<br />

abdomen and pelvis revealed a large loculated mass in the medial right thigh with local invasion. A PET<br />

scan did not show any areas <strong>of</strong> hypermetabolic activity <strong>of</strong> the lung. The patient was given aggressive IV<br />

hydration, as well as bisphosphonate and calcitonin therapy. 25-hydroxy vitamin D as well as PTH levels<br />

were both below normal range, and a parathyroid hormone-related protein (PTHrP) level was elevated.<br />

These findings best represented paraneoplastic production <strong>of</strong> PTHrP from a primary cutaneous SCC. The<br />

patient experienced only mild improvement <strong>of</strong> his mental acuity and hypercalcemia. He declined<br />

palliative chemotherapy and radiation therapy, and he was discharged to a hospice and died several<br />

days later.<br />

DISCUSSION: Although HHM has been identified in a significant number <strong>of</strong> primary SCC <strong>of</strong> the lung, it<br />

has only rarely been reported with cutaneous SCC. Even more exceptional is the presence <strong>of</strong><br />

concomitant hyperleukocytosis syndrome. We present a case <strong>of</strong> hypercalcemia-hyperleukocytosis<br />

syndrome in relationship to cutaneous SCC, <strong>of</strong> which only a small number <strong>of</strong> cases have been reported.<br />

This case supports the finding that the presence <strong>of</strong> this paraneoplastic combined process is a poor<br />

prognostic indicator. Future studies may indicate that the presence <strong>of</strong> hypercalcemia-hyperleukocytosis<br />

syndrome may independently predict survivability when compared to the use <strong>of</strong> standard TNM staging.<br />

Chapter Winning Abstract Rickettsia Parkeri, An Emerging Spotted Fever Group Rickettsiosis<br />

Daniel Robert Hatcher, DO (Associate) Peter Blatz, MD (Member) Erin Weeden, MD Nicholas G. Conger,<br />

MD (Member)<br />

INTRODUCTION: The most common cause <strong>of</strong> spotted fever in the United States is Rocky Mountain<br />

Spotted Fever (RMSF) caused by Rickettsia rickettsii. However, multiple regionally associated and<br />

vector specific reckettsiae species have been identified. Recently, Rickettsia parkeri has been described<br />

as an emerging pathogen, causing an eschar-associated Spotted Fever Group Rickettsiosis (SFGR) in the<br />

SE US region, including the Gulf Coast.<br />

CASE PRESENTATION: #1 A 57-year-old male, who lives and works in a wooded area adjacent to a<br />

swamp in Louisiana, presented with a painful pustule on his right shin following a stinging bite to that<br />

area. He was given cephalexin 500mg QID empirically without improvement. Over the next 5 days, the<br />

wound progressed to a 1.5 cm black eschar with surrounding erythema. The patient subsequently<br />

developed chills, fever to 102.6F, headache, night sweats, and a spotted maulopapular red rash over this<br />

torso and extremities. He had painful red nodules on his hands and fingers. ESR was 59. He was<br />

treated with doxycycline with dramatic resolution <strong>of</strong> symptoms. Serology for SFGR AB IgG was positive<br />

at 1:1024 and R. parkeri IgG was >1:512. Lesion biopsies revealed perivascular inflammatory cell<br />

infiltrates involving the full thickness <strong>of</strong> the dermis, with focal vasculitis and panniculitis. Pathology<br />

specimens sent to the CDC stained positive for SFGR organisms within the tissue. Given the<br />

geographical area and clinical presentation, this is diagnostic for R. parkeri.<br />

#2 A 48-Year-Old man was sent for consultation for suspected Lyme disease following a tick bite. This<br />

patient had fever, chills, diffuse myalgias, arthralgias, and developed a spotted rash. All symptoms<br />

dramatically improved with doxycycline. Lyme Ab was repeatedly negative, but SFGR AB IgG was<br />

positive at 1:256 four weeks after presentation and R. parkeri IgG was 1:512. The constellation <strong>of</strong><br />

symptoms, positive AB, and geographic location where the bite was sustained is highly suggestive <strong>of</strong> R.<br />

parkeri rickettsiosis.<br />

DISCUSSION: Close attention needs to be paid in a suspected SFGR to its distinguishing characteristics<br />

for an accurate diagnosis and prognosis. These cases illustrate classic presentations for Rickettsia pareri,<br />

an emerging infectious disease that is very similar to, thought less sever than Rocky Mountain Spotted<br />

Fever. Case reports are few, and cases occur from the east coast <strong>of</strong> Texas to Florida, clustering around<br />

the South-East US coastal areas. Cases are likely either missed, or mistaken for RMSF or Lyme disease,<br />

neither <strong>of</strong> which are reported to occur in these areas. It is important for health care providers in the<br />

coastal regions inhabited by Amblyomma maculatum to be aware <strong>of</strong> this infection, and to treat<br />

appropriately with doxycycline.<br />

INTRODUCTION:Anti-N-Methyl-D-Aspartate receptor (NMDAR) antibody encephalitis is a newly<br />

recognized syndrome that causes severe psychotic and neurologic symptoms, which rapidly prove fatal<br />

if not recognized and treated early. A single institution has reported over 400 cases in just over 3<br />

years[1] suggesting that it may be the most common antibody associated with encephalitis. Here we<br />

present a case <strong>of</strong> NMDAR encephalitis that occurred as a paraneoplastic manifestation <strong>of</strong> bilateral<br />

ovarian teratomas<br />

CASE PRESENTATION: A 16-year old woman presented to the Emergency Room after an altercation<br />

with her father. Her mother reported a one week history <strong>of</strong> psychotic symptoms including: insomnia,<br />

severe agitation, combativeness, and auditory hallucinations. The patient was confused, lacked insight,<br />

and exhibited a tangential thought process. She was discharged from the Emergency Room to a<br />

pediatric mental health facility where she was started on haloperidol, olanzapine, and depakote. Five<br />

days after admission she developed a fever <strong>of</strong> 105 degrees Fahrenheit, exhibited diffuse muscular<br />

rigidity, and became unresponsive. She was admitted to the medical ICU, intubated, and treated with<br />

dantrolene for presumed neuroleptic malignant syndrome. After 4 days <strong>of</strong> supportive care and failure to<br />

improve on dantrolene, a CT abdomen was performed and revealed bilateral ovarian masses consistent<br />

with ovarian teratomas. A lumbar puncture was performed and sent to the Mayo Clinic for work-up <strong>of</strong> a<br />

suspected paraneoplastic syndrome. On day twelve <strong>of</strong> her hospital course the tumors were resected;<br />

pathology later confirmed the masses to be poorly differentiated teratomas. The patient was treated<br />

empirically for NMDAR encephalitis with intravenous immunoglobulin and plasma exchange, however,<br />

she did not improve with therapy. She remained unresponsive and exhibited choreiform movement,<br />

which was unsuccessfully treated with haloperidol, phenobarbital, and ziprasidone. Thirty-five days<br />

after admission she was weaned from the ventilator, and one week later the NMDAR antibody returned<br />

positive. Several days later she was discharged from the ICU, to the general ward. She remains<br />

unresponsive and does not follow commands.<br />

DISCUSSION: This case was diagnostically and therapeutically challenging, and highlights the<br />

masquerading nature <strong>of</strong> this disease. We emphasize the importance <strong>of</strong> ruling out organic causes <strong>of</strong><br />

psychosis, especially in young adults and children. We also stress the need to develop more rapid<br />

diagnostic tests for serum and cerebrospinal fluid.<br />

The Case <strong>of</strong> the mysterious fever and rash: DRESS Syndrome caused by Goserelin<br />

Alycia Cleinman, MD Justin Qualls, MD Andree Burnett, MD<br />

INTRODUCTION: Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) syndrome is defined<br />

by the presence <strong>of</strong> a rash with three additional criteria <strong>of</strong>: fever, hematologic abnormalities,<br />

lymphadenopathy, or organ involvement. DRESS syndrome is typically <strong>of</strong> delayed onset, occurring 2 to 6<br />

weeks after initiation <strong>of</strong> the <strong>of</strong>fending drug. Goserelin has been previously associated with local skin<br />

reactions, but not DRESS syndrome. Here, we present the first reported case <strong>of</strong> DRESS syndrome<br />

associated with goserelin.<br />

CASE PRESENTATION: A 65-year-old white man with known prostate cancer presented to an<br />

emergency department with fever and diffuse rash. Two weeks prior to presentation, the patient<br />

received a depot injection <strong>of</strong> goserelin. He subsequently developed a local pruritic rash on his chest that<br />

later progressed to his arms, legs, palms, groin, and buttocks; two days prior to presentation he<br />

developed a high-grade fever.<br />

Initial examination revealed hepatosplenomegaly. In addition, an erythematous maculo-papular rash,<br />

was present on his abdomen, buttocks, back, and palms, as well as on all extremities, but spared his<br />

mucosa. During his hospitalization, the rash developed a targetoid appearance. Admission labs revealed<br />

bandemia without eosinophilia and a mild AST elevation. Within a few days, eosinophilia developed with<br />

resolution <strong>of</strong> the AST elevation. Additional investigations failed to identify an auto-immune, viral, or<br />

bacterial etiology. History revealed no possible exposures other than goserelin, to account for the<br />

presenting symptoms.<br />

The patient was empirically initiated on systemic and topical corticosteroids for a suspected adverse<br />

reaction to goserelin. A skin biopsy <strong>of</strong> the left gluteal region was performed and pathology reported<br />

“superficial perivascular lymphohistiocytic dermatitis with eosinophils and neutrophils”. Dermatology<br />

was consulted and confirmed the clinical presentation was consistent with DRESS syndrome, likely due<br />

to goserelin. Upon discussion with Urology, it was revealed that the injection would last for three<br />

months with no possible intervention for its discontinuation.<br />

DISCUSSION: We present here a unique case <strong>of</strong> DRESS syndrome, likely caused by goserelin. Our case<br />

highlights the importance <strong>of</strong> considering depot goserelin injections as a cause <strong>of</strong> DRESS syndrome. While<br />

we were unable to withdraw the <strong>of</strong>fending drug, our patient’s outcome was still favorable. We attribute<br />

this to his completion <strong>of</strong> a course <strong>of</strong> corticosteroids and our careful observation <strong>of</strong> the patient’s<br />

subsequent clinical course.<br />

Electrocardiographic Brugada Pattern Induced By Quetiapine Overdose<br />

Sushant Khaire, MD Other Authors: Harsha Nagarajarao, MD; Santo Marcus Borganelli, MD; Robert<br />

Marshall, MD; Senior Author: Ernest Matthew Quin, MD.<br />

INTRODUCTION: Brugada syndrome is a genetic disorder characterized by a mutation in the sodium<br />

channel SCN5A gene; affected individuals have an abnormal electrocardiogram (ECG) pattern, and<br />

sudden cardiac death can occur due to cardiac arrhythmias. ECG patterns similar to Brugada syndrome<br />

have been observed with the use <strong>of</strong> certain drugs, including sodium channel blocking Class I<br />

antiarrhythmic drugs, selective serotonin reuptake inhibitors (SSRI), tricyclic antidepressants (TCA), and<br />

other antidepressants. In some patients this is thought to be related to an inducible Brugada pattern,<br />

which may also be associated with cardiac arrhythmias. Here we present a case <strong>of</strong> induced Brugada<br />

pattern due to quetiapine overdose.<br />

CASE PRESENTATION: A sixty-one year old male was brought to the emergency department following<br />

a suicide attempt by overdose <strong>of</strong> quetiapine and zolpidem. He had recently started quetiapine after<br />

stopping citalopram. On presentation he was awake, but confused and agitated. He was<br />

hemodynamically stable, diaphoretic, had pinpoint pupils, and a flushed appearance. He had tremors in<br />

all four extremities. ECG on presentation showed ST-segment elevation in V1, V2 and V3 consistent with<br />

Brugada pattern. Troponin and electrolytes were within normal ranges. He was admitted to the<br />

intensive care unit and quetiapine and zolpidem were held. Serial ECGs demonstrated eventual<br />

normalization <strong>of</strong> ST segments QT interval. Mental health was consulted and he was eventually<br />

transferred for medication adjustments, but had no arrhythmias during the hospitalization.<br />

DISCUSSION: Brugada pattern on ECG can be induced by several factors including medications<br />

mentioned above as well as lithium, cocaine, bupivacaine, prop<strong>of</strong>ol, verapramil, beta blockers, and<br />

nitrates. Here we present the first reported case, to our knowledge, <strong>of</strong> Brugada pattern induced by<br />

quetiapine. Optimal management for patients who have transient Brugada pattern induced by<br />

medications is not clear, although most seem to have a good prognosis. While genetic defects such as<br />

those associated with the SCN5A gene can be unmasked by certain agents, the arrhythmic risk<br />

associated with mutations having low penetrance is not currently known. In selected cases with<br />

syncope or palpitations consistent with a cardiac arrhythmia, further electrophysiologic evaluation may<br />

be beneficial. Based on the occurrence <strong>of</strong> Brugada pattern with quetiapine and other antidepressant<br />

medications, however, screening with baseline and periodic ECGs is warranted.<br />

The Myocardial Bandit: A Case Of Left Internal Mammary Artery Steal Phenomenon<br />

; Sanjay Maniar, MD, Elisa Bradley, MD and Edward Geltman, MD<br />

INTRODUCTION:<br />

Coronary artery bypass graft (CABG) has remained the long-standing definitive therapy for multi-vessel<br />

coronary artery disease (CAD). The left internal mammary artery (LIMA) is generally considered the<br />

vessel <strong>of</strong> choice for revascularization <strong>of</strong> the left anterior descending artery (LAD). The mammary steal<br />

phenomenon has been described as the interval development <strong>of</strong> angina due to the reversal <strong>of</strong> blood<br />

flow within a previously constructed internal mammary artery coronary conduit. We present a unique<br />

case <strong>of</strong> the steal phenomenon due to a fistulous connection between the proximal LIMA with the left<br />

pulmonary veins.<br />

CASE PRESENTATION: A 78-year-old white gentleman with history <strong>of</strong> coronary artery disease, threevessel<br />

coronary artery bypass graft (CABG) (LIMA to left anterior descending artery (LAD), saphenous<br />

venous graft (SVG) to a diagonal artery, and SVG to posterior descending artery), congestive heart<br />

failure and dual-chamber pacemaker placement who presented with recurrent chest pain and dyspnea<br />

on exertion. His chest pain began in his distal left arm and progressed proximally at rest, worsened with<br />

exercise and resolved following the administration <strong>of</strong> nitroglycerin. All labs, including troponin-I and<br />

creatinine kinase MB fraction (CK-MB) were within normal limits. Electrocardiogram demonstrated no<br />

changes. Regadenoson nuclear stress test was unchanged from previous, showing a moderate-sized<br />

anteroapical infarct and large infero- and inferolateral infarct. Cardiac catheterization demonstrated a<br />

fistulous connection between the LIMA graft and an intercostal artery side branch emptying to the left<br />

atrium via the pulmonary veins. Follow-up exercise treadmill nuclear stress test was suboptimal to<br />

evaluate for ischemia in the territory <strong>of</strong> the LIMA graft due to attenuated heart rate response. The<br />

patient ultimately underwent coil embolization <strong>of</strong> the fistulous connection, which resulted in improved<br />

blood flow to his LAD. Following the procedures, he had symptomatic improvement and increased<br />

exercise tolerance.<br />

DISCUSSION: Mammary steal phenomenon has been variably documented and is a rare cause <strong>of</strong><br />

recurrent angina in patients who have previously undergone CABG surgery, specifically when LIMA side<br />

branches have not been ligated. Current theories regarding the etiology <strong>of</strong> preferential flow is the<br />

presence <strong>of</strong> lower peripheral resistance in the pulmonary vascular bed, compared to higher coronary<br />

resistance. The patient underwent successful coil embolization with immediate symptomatic<br />

improvement. This case highlights the potential for symptomatically significant blood flow steal from<br />

unligated LIMA side branches, which can compromise flow to the coronary vascular bed, and the novel<br />

advances in therapy available in the current era <strong>of</strong> medicine.<br />

Foot Drop and Urinary Retention Following Disseminated Varicella Zoster Infection<br />

Sina Jasim, MD Co- authors: Srikanth Damodaram,MD, Stanley Iyadurai,MD, Ganesh Kudva, MD<br />

INTRODUCTION: Herpes Zoster virus infection is usually associated with sensory nerve damage. Motor<br />

neuropathy secondary to Zoster infection has been rarely reported and mostly affects the facial nerve.<br />

Nerves <strong>of</strong> the lower limbs and the sacral spinal cord are usually spared. Here, we report a rare<br />

presentation with foot drop and bladder dysfunction associated with varicella zoster virus (VZV)<br />

infection, indicating discrete involvement <strong>of</strong> central and peripheral nervous systems.<br />

CASE PRESENTATION: A 73-year old woman with chronic lymphocytic leukemia, presented with a 2week<br />

history <strong>of</strong> walking difficulty. The patient was initially evaluated for back pain one month prior and<br />

had received a local steroid injection with no improvement. Approximately a week after the steroid<br />

injection, she noticed that the pain involved the right leg, and that she had difficulty walking. The<br />

patient also reported difficulty voiding during the same period <strong>of</strong> time. Notably, she had also<br />

complained <strong>of</strong> a “rash” on the right forehead prior to the steroid injection, which became worse to<br />

involve the arms, trunk and legs.<br />

Examination revealed multiple healing erythematous, crusting skin lesions on the face and right<br />

forehead, as well as scattered lesions on the trunk and the arms. Confluent erythematous crusting<br />

lesions were noted on the antero-lateral aspects <strong>of</strong> the right leg. Significant weakness <strong>of</strong> the right<br />

peroneal-innervated muscles was noted. The right ankle reflex was absent. Abdominal examination<br />

revealed suprapubic fullness and urinary retention was confirmed by measurement <strong>of</strong> post-void residual<br />

volumes.<br />

Basic laboratory evaluation revealed an increased white blood cell count consistent with chronic<br />

lymphocytic leukemia. Lumbar puncture revealed a nucleated cell count <strong>of</strong> 245 (91% lymphocytes),<br />

normal protein and glucose, and elevated VZV immunoglobulin titer. Serological evaluation revealed<br />

elevated Varicella Zoster antibody titer. Biopsy <strong>of</strong> the skin lesion revealed the presence <strong>of</strong> VZV DNA, as<br />

demonstrated by positive polymerase chain reaction. MRI <strong>of</strong> the thoracic and lumbar spine did not<br />

reveal spinal cord compression or involvement. Nerve conduction study showed evidence <strong>of</strong> right sciatic<br />

neuropathy with complete involvement <strong>of</strong> the right peroneal nerve and partial involvement <strong>of</strong> the tibial<br />

nerve. The patient was treated with acyclovir and gabapentin. The urinary retention was treated with<br />

intermittent catheterization and bladder training, and the foot drop with assistive devices.<br />

DISCUSSION: VZV usually affects the dorsal root ganglion and corresponding dermatomes.To our<br />

knowledge, this is the first case to document a discrete involvement <strong>of</strong> central and peripheral nervous<br />

systems secondary to infection with VZV, suggesting multifocal vasculitis/vasculopathy as an etiology.<br />

This observation adds to the spectrum <strong>of</strong> neurological complications <strong>of</strong> VZV in immune-compromised<br />

host. From a clinical standpoint, the use <strong>of</strong> steroids in the context <strong>of</strong> VZV infection should be rigorously<br />

examined.<br />

Common Variable Immunodeficiency (CVID): Gotta Know The Common Stuff!!!<br />

Anilkumar Katta MD,Walter Gribben MD,James Temprano MD. Department <strong>of</strong> Internal Medicine,<br />

Division <strong>of</strong> Immunobiology, Allergy and Clinical Immunology section, Saint Louis University, St. Louis MO.<br />

INTRODUCTION: Common variable Immunodeficiency (CVID) is the commonest symptomatic primary<br />

immunodeficiency characterized by impaired B-cell differentiation with defective immunoglobulin<br />

production. CVID poses challenges to the internist because <strong>of</strong> its heterogeneity in presentation, delay in<br />

diagnosis, recurrent infections and common misconception <strong>of</strong> being “a rare disease”.<br />

CASE PRESENTATION: A 19-year-old active duty marine with history <strong>of</strong> chronic sinusitis s/p sinus<br />

surgery and recurrent pneumonias presented to outpatient clinic with back pain, he was treated with<br />

Vicodin and Flexril. Over the course <strong>of</strong> 5 days he developed dizziness, worsening <strong>of</strong> back pain, nausea<br />

and vomiting. In this visit he was prescribed physical therapy. After this visit patient fell downstairs and<br />

became unresponsive. In ED physical exam was significant for dilated and fixed right pupil. Head CT<br />

revealed dilated ventricles and left thalamic infarct, emergent vetriculostomy was performed. Patient<br />

was intubated and transferred to ICU. CSF culture and blood cultures grew Streptococcus Pneumoniae.<br />

Patient continued to have high fever and high WBC count even with broad-spectrum antibiotic<br />

coverage; CT scan <strong>of</strong> chest, abdomen and pelvis were performed which revealed pyomyositis with six<br />

different abscesses all over the body. Immunodeficiency was suspected, further work up revealed that<br />

patient is HIV non-reactive and has very low levels <strong>of</strong> IgG, IgM and IgA. Peripheral blood flow cytometry<br />

showed decreased B-lymphocytes and absent switched memory B-lymphocytes confirming the diagnosis<br />

<strong>of</strong> CVID. Patient was treated with IVIG, aggressive debridement and prolonged course <strong>of</strong> antibiotics.<br />

After 3 months <strong>of</strong> hospital stay patient was discharged to rehabilitation.<br />

DISCUSSION: High index <strong>of</strong> suspicion is needed for the diagnosis <strong>of</strong> CVID as patients most <strong>of</strong>ten present<br />

with recurrent sinopulmonary infections and early diagnosis improves the mortality. Most <strong>of</strong>ten<br />

patients are diagnosed form 5-10 yrs after the onset <strong>of</strong> CVID. Jeffrey Modell foundation's "10 warning<br />

signs <strong>of</strong> primary Immunodeficiency for adults" is a good screening tool for primary care providers for<br />

identifying primary immunodeficiencies. CVID patients have poor response to vaccines and all live<br />

vaccines are contraindicated.<br />

AIDS Patient with Secondary Syphilis Presenting with Nonreactive FTA-AB: A Case Study<br />

Dinadelle B. Viola, MD (Associate), Charles Krasner, MD (Member), University <strong>of</strong> Nevada School <strong>of</strong><br />

Medicine<br />

INTRODUCTION: Syphilis is a sexually transmitted disease caused by the spirochete Treponema<br />

pallidum. Syphilis infection can present and mimic wide varieties <strong>of</strong> clinical disease processes as well as<br />

affect multiple organs in the body. This case describes an AIDS patient’s unusual presentation with<br />

ocular syphilis and the difficulty <strong>of</strong> diagnosing the infection.<br />

CASE PRESENTATION: The patient is a 42-year-old male with AIDS and chronic candida infections. His<br />

CD4 count was 171 cells/ml and his viral load was 7000 copies/ml.<br />

In May 2010, the patient was referred to an ophthalmologist after a three-month period <strong>of</strong> bilateral<br />

visual flashes, floaters and decreased vision. He was diagnosed with diffuse chronic vitritis with<br />

secondary optic neuritis from candida infections, and was treated with oral fluconazole. But after two<br />

weeks <strong>of</strong> post-treatment follow-ups, he was found to have worsening retinitis and uveitis. Therefore, he<br />

was admitted for empiric therapy with IV fluconazole. The treatment resulted in the reduction in the<br />

amount <strong>of</strong> detritus in his eyes and improvement <strong>of</strong> the retinal lesions. The patient also reported some<br />

improvement <strong>of</strong> his vision.<br />

In June 2010, the patient’s blood tests showed a CD4 count <strong>of</strong> 238 and positive serology tests for HSV1<br />

and HSV2. Tests for toxoplasma, lyme, nontreponemal and treponemal were negative. However, soon<br />

after the test, his visual complaints recurred on each eye, two weeks apart. He was then treated for<br />

herpetic endophthalmitis with IV acyclovir and underwent pars plana vitrectomy with intravitreal<br />

antibacterial and antiviral injections. After that, he reported some vision improvement.<br />

Repeat serological tests were done due to his recurrent visual complaints. Pertinent findings revealed<br />

positive HSV1 and HSV2, reactive RPR, VDRL, and FTA-Ab with RPR titer <strong>of</strong> 1:1024. At that point, he was<br />

treated with IV penicillin that resulted in complete resolution <strong>of</strong> his visual symptoms and his RPR titer<br />

had decreased to 1:4.<br />

DISCUSSION: This case illustrates two points: (1) the complexity <strong>of</strong> diagnosis in the immunecompromised<br />

and (2) the importance <strong>of</strong> recognizing that serology tests for syphilis infection can be<br />

nonreactive in a small percentage <strong>of</strong> patients with HIV. The FTA-Ab serologic test had been previously<br />

reported as 100% sensitive in patient with secondary syphilis (USPSTF 2004), but was nonreactive while<br />

the patient was exhibiting symptoms <strong>of</strong> secondary syphilis. Repeated serological tests for syphilis may<br />

be needed to confirm or exclude syphilis infection in this patient population. A delay in the diagnosis <strong>of</strong><br />

ocular syphilis and the failure to treat can result in vision loss. Therefore, a high index <strong>of</strong> suspicion for<br />

syphilis should be maintained in HIV/AIDS patients and empiric treatment should be considered.<br />

Ascites in Pregnancy: from Erythema Nodosum to Peritoneal Coccidioidomycosis<br />

Jason W Suszko, M.D. Whitney Sh<strong>of</strong>ner B.A., Reza Vaghefi, M.D., Mahendran Jayaraj M.D., Jitendra<br />

Adepu, M.D., Nicole Davey, M.D.<br />

INTRODUCTION: Coccidioides immitis is a soil-dwelling, dimorphic fungus endemic to the<br />

southwestern United States, especially California’s San Joaquin Valley and Arizona. The clinical<br />

manifestations are heterogeneous and range from asymptomatic to San Joaquin Valley Fever, and rarely<br />

to dissemination. Traditional risk factors for dissemination include immunosuppressive therapy,<br />

HIV/AIDS, African-<strong>American</strong> and Filipino ethnicity, and pregnancy.<br />

CASE PRESENTATION: A 39-year-old African-<strong>American</strong> female gravida 10 para 6-0-3-6 at 24 weeks<br />

gestation was admitted with minimal abdominal pain, large ascites, and no respiratory complaints. She<br />

was sent from the obstetrics clinic for her ascites and had a paracentesis performed in the hospital.<br />

Serum-ascites albumin gradient was 0.9 and clear fluid was drained from the peritoneal cavity. Initial<br />

work-up was unrevealing and etiology was uncertain. Patient remained on the obstetrics floor for<br />

supportive maternal and fetal care. Upon further history, patient was noted to have a cough productive<br />

<strong>of</strong> white sputum and subjective fevers before presenting to the hospital. She was evaluated in California<br />

in the beginning <strong>of</strong> her pregnancy for a “rash” and “pneumonia-like illness.” The rash was consistent<br />

with erythema nodosum and her coccidioides titers were positive. Patient did not follow up for<br />

treatment. Initially the etiology <strong>of</strong> our patient’s ascites remained unclear. However, after we obtained<br />

old medical records and a thorough history, coccidioides serology was ordered and both IgM and IgG<br />

were elevated. Patient was diagnosed with disseminated coccidioidomycosis in pregnancy with a history<br />

<strong>of</strong> erythema nodosum. Patient was started on fluconazole and ascites progressively decreased.<br />

DISCUSSION: This case illustrates the variation that can be seen in disseminated coccidioidomycosis.<br />

Patients with dissemination rarely present with peritoneal involvement and ascites as our patient did. In<br />

addition, her history <strong>of</strong> erythema nodosum generally favors a better prognosis and decreases the risk <strong>of</strong><br />

dissemination. This case is an atypical presentation <strong>of</strong> disseminated coccidioidomycosis and documents<br />

a patient with erythema nodosum in pregnancy who then developed disseminated<br />

coccidioidomycosis. In our clinical practice, this case will reinforce the importance <strong>of</strong> obtaining an<br />

excellent history and skin exam as well as strengthen our clinical judgment.<br />

A Case <strong>of</strong> Proliferative Glomerulonephritis with Monoclonal IgG Deposits<br />

Reza Vaghefi-Hosseini, MD Second Authors: Amarnathreddy Annapureddy, MD, Sandhya Wahi-Gururaj,<br />

MD<br />

INTRODUCTION: Proliferative Glomerulonephritis with Monoclonal IgG Deposits (PGNMID) is a novel<br />

form <strong>of</strong> glomerulonephritis that has been described within the last ten years and is related to<br />

monoclonal IgG deposition which could not be assigned to any <strong>of</strong> the established categories <strong>of</strong><br />

glomerular involvement by dysproteinemia (type 1 cryoglobulinemia, light and heavy chain deposition<br />

disease (LHCDD), and immunotactoid glomerulonephritis). This entity is rarer than other forms <strong>of</strong><br />

dysproteinemia-related renal diseases, and may pose diagnostic challenges in renal biopsy<br />

interpretation. We describe a case <strong>of</strong> PGNMID below.<br />

CASE PRESENTATION: A 60 year-old white female with history <strong>of</strong> hypertension, COPD, and hepatitis C<br />

infection presented to the ER complaining <strong>of</strong> generalized weakness and swelling <strong>of</strong> the lower extremities<br />

for the past 2 months. On examination, the patient’s blood pressure was elevated, her lung exam<br />

revealed diffuse wheezing bilaterally, and bilateral 2+ lower extremity pitting edema. Laboratory studies<br />

were significant for anemia, hypoalbuminemia, renal insufficiency (Creatinine: 5.6 mg/dL), nephrotic<br />

range proteinuria (Uprot / Ucreat =13.42) and hematuria. The patient was admitted with a diagnosis <strong>of</strong><br />

acute kidney injury. Ultrasound <strong>of</strong> the kidneys revealed normal sized kidneys without hydronephrosis.<br />

Urine immun<strong>of</strong>ixation revealed increased total protein without any heavy or light chain. Serum<br />

immun<strong>of</strong>ixation was negative for M-Spike with normal immunoglobulin levels. Further evaluation<br />

including autoimmune studies ANCA, anti GBM antibody, ASO titer, and bone marrow biopsy were all<br />

normal. Pathology from her kidney biopsy revealed: “proliferative glomerulonephritis with monoclonal<br />

IgG with approximately 70% crescents formation”. During the hospital course, the patient’s renal<br />

function worsened and she ultimately required hemodialysis.<br />

DISCUSSION: Pathogenesis <strong>of</strong> PGNMID is not well known. The absence <strong>of</strong> underlying diseases including<br />

hematologic malignancies and the light-chain and heavy-chain subclass restriction argue against antigenantibody<br />

immune complex deposition. Furthermore, most patients do not develop detectable M protein<br />

during long term follow-up.<br />

Histologically, PGNMID mimics immune-complex type glomerulonephritis on light microscopy and<br />

electron microscopy, however, by immun<strong>of</strong>luorescence, the glomerular deposits are monoclonal,<br />

staining for a single light-chain isotype and a single heavy-chain subclass. The disease affects adults and<br />

is more common in white and female individuals. Most patients present with nephrotic-range<br />

proteinuria and hematuria with or without renal insufficiency. Prognosis is variable, with nearly one<br />

quarter <strong>of</strong> patients progressing to ESRD within 2-3 years. Treatment is not well established.<br />

This case presents a rare and novel form <strong>of</strong> glomerulonephritis with unknown pathogenesis and<br />

challenging pathologic findings. There are very few case reports and case series in the literature with the<br />

same characteristic as our patient. Moreover, the treatment options are not well studied. Clinicians<br />

should be aware <strong>of</strong> this entity as a new class amongst the renal diseases associated with monoclonal<br />

gammopathy.<br />

NEW HAMPSHIRE POSTER FINALIST - CLINICAL VIGNETTE William A<br />

Hammond, MD<br />

Chapter Winning Abstract<br />

W. Adam Hammond, MD<br />

INTRODUCTION:Purpuric skin lesions are a relatively infrequent presentation to primary care clinics<br />

and emergency departments and the differential is broad, including many potentially life-threatening<br />

diagnoses. It is important for the clinician to have a framework for excluding serious conditions and<br />

appropriately initiating a work-up to narrow the differential in an efficient manner. Antiphospholipid<br />

antibody syndrome, a somewhat newly recognized condition, should be included as a cause <strong>of</strong> purpura.<br />

CASE PRESENTATION: A 59 year old woman with fairly insignificant past history aside from mild<br />

psoriasis and osteoarthritis presents to the Emergency Department (ED) with complaint <strong>of</strong> black lesions<br />

on her left forearm, both thighs, and right breast. The lesions started about three weeks prior as a single<br />

round, black, non-ulcerative lesion on her left forearm that was only mildly painful on palpation. This<br />

resolved over a few days and two weeks later, a colleague noted an erythematous, well-circumscribed<br />

lesion on her right face consistent with erysipelas. She visited her PCP and was started on a course <strong>of</strong><br />

lev<strong>of</strong>loxacin for erysipelas. The next day, she noticed multiple small black lesions which started about<br />

the size <strong>of</strong> a fingernail but grew to up to six centimeters over the next day. They were neither painful<br />

nor pruritic, however appeared concerning and prompted evaluation in an ED. She was evaluated by<br />

Dermatology and transferred to the nearby tertiary care hospital for definitive evaluation. Initial exam<br />

revealed normal vital signs and unremarkable physical exam aside from round, well-demarcated deep<br />

purple to black lesions with slight central necrosis, from three to six centimeters in largest diameter.<br />

They were again not painful. Initial laboratory workup revealed normal complete blood counts,<br />

complete metabolic panel including liver tests, coagulation studies, and urinalysis. Skin biopsy was<br />

obtained. Autoimmune labs revealed mildly positive antinuclear antibody at 1:80 with weakly positive<br />

anti-double stranded DNAat 1:10. Peripheral antinuclear cytoplasmic antibody was positive, however<br />

myeloperoxidase antibody was negative. Anti-streptolysin-O antibody returned largely elevated. Skin<br />

biopsy returned showing intravascular thrombosis with no evidence <strong>of</strong> vasculitis. D-dimer returned<br />

elevated and a thrombosis panel was sent which returned negative except mild elevation <strong>of</strong> fibrinogen<br />

and activated protein C resistance. Lupus anticoagulant and beta-2 glycoprotein-1 IgG and IgM were<br />

negative, however anti-cardiolipin IgG returned moderately positive. The patient remained quite stable<br />

without any additional symptoms and was discharged after three days in the hospital for this evaluation<br />

with the diagnosis <strong>of</strong> Streptococcus induced antiphospholipid antibody formation. Subsequent testing<br />

more than three months after discharge revealed negative antibodies.<br />

DISCUSSION: The work up <strong>of</strong> purpuric skin lesions can typically be completed in the outpatient setting<br />

but requires that serious causes be ruled out rapidly. In order to do so, a physician must have an<br />

understanding <strong>of</strong> clinical indicators which portend a dangerous prognosis. History will give much <strong>of</strong> the<br />

information and may include recent initiation <strong>of</strong> medications or recent illness. Febrile patients must be<br />

considered for thrombotic thrombocytopenic purpura or hemolytic uremic syndrome in the right clinical<br />

setting. Review <strong>of</strong> systems and exam should be complete including mental status and thorough skin<br />

evaluations. Labs including complete blood counts for platelets, coagulation studies, and complete<br />

360


metabolic panel to investigate the liver and kidney for evaluation for end organ damage are a critical<br />

early step in the evaluation. Skin biopsy should be performed early in order to differentiate between<br />

vasculitic, necrotic, or thrombotic lesions. A patient with low platelets or abnormal coagulation studies<br />

may warrant admission for monitoring while further evaluation is continued. The patient in the clinical<br />

presentation had extensive laboratory work-up which could potentially have been truncated if early skin<br />

biopsy was performed, as work-up for vasculitis could have ended at that point. The diagnosis <strong>of</strong> antiphospholipid<br />

antibodies induced by erysipelas was presumptively made, however definitive diagnosis <strong>of</strong><br />

antiphospholipid antibody syndrome requires persistence <strong>of</strong> antibodies after at least twelve weeks. This<br />

was tested after discharge and revealed negative antibodies indicating a transient nature to their<br />

presence in this case.<br />

IMMUNE(IDIOPATHIC) THOMBOCYTOPENIC PURPURA IN SOLID TUMORS, AN UNDERREPRESENTED<br />

PARANEOPLASTIC PHENOMENON?<br />

Sung-hee Choi, MD<br />

INTRODUCTION: Immune(Idiopathic) thrombocytopenic purpura (ITP) is a rare cause <strong>of</strong><br />

thrombocytopenia in solid tumors. There have only been scant case reports indicating an association<br />

between solid tumors (especially, breast and lung) and ITP. Whether ITP has an established<br />

paraneoplastic phenomenon with a predictive or prognostic value in solid tumors remains a question.<br />

CASE PRESENTATION: A 66-year-old woman was admitted to the hematology service for management<br />

and treatment <strong>of</strong> pr<strong>of</strong>ound thrombocytopenia. This was noted on pre-operative screening workup for<br />

surgical excision <strong>of</strong> a recently diagnosed localized invasive melanoma. Patient had noticed easy bruising<br />

over the course <strong>of</strong> a year. She denied history <strong>of</strong> bleeding, initiation <strong>of</strong> new medications or<br />

recent illness. Past medical history was significant for hypertension, non-insulin dependent diabetes,<br />

hyperlipidemia, rheumatic fever as a child, newly diagnosed invasive localized melanoma along the<br />

posterior neck and remote history <strong>of</strong> pulmonary embolism associated with use <strong>of</strong> contraceptives twenty<br />

years ago. She was a previous heavy smoker with occasional alcohol use. Family history was significant<br />

for hypertension, hyperlipidemia, colon cancer and pancreatic cancer. Upon admission, blood pressure<br />

was significantly elevated with remainder <strong>of</strong> vital signs within normal limits. Physical examination<br />

showed significant petechiae along the posterior oropharynx, anterior aspects <strong>of</strong> the shins and upper<br />

extremities with scattered ecchymosis, diffuse systolic murmur and crackles auscultated along the right<br />

lung base. There was no evidence <strong>of</strong> active bleeding.<br />

Complete blood count showed a marked thrombocytopenia with a platelet count <strong>of</strong> 4x10(3)/mcL. There<br />

was no evidence <strong>of</strong> a leukoerythroblastic reaction; white blood count (WBC) and hemoglobin were<br />

normal. Laboratory workup included a negative anti-nuclear antibody without evidence <strong>of</strong> disseminated<br />

intravascular coagulopathy or hemolysis. Thyroid studies and viral studies including human<br />

immunodeficiency virus screening, cytomegalovirus, parvovirus, epstein-barr virus were all negative.<br />

Peripheral smear results showed thrombocytopenia with normal-appearing neutrophils and<br />

erythrocytes.<br />

Treatment was initiated with intravenous immunoglobulins and a seven week course <strong>of</strong> steroid taper .<br />

There was complete normalization <strong>of</strong> platelet counts. However, as part <strong>of</strong> a complete staging workup for<br />

melanoma during hospitalization, CT scan <strong>of</strong> the chest showed a 5.8 x 5.9 cm peripherally enhancing,<br />

centrally necrotic, lobulated right hilar mass with peripheral collapse <strong>of</strong> the right middle lobe and<br />

surrounding interstitial thickening worrisome for lymphangitic involvement. This mass was later<br />

confirmed to be adenocarcinoma <strong>of</strong> the lung. Patient subsequently underwent resection <strong>of</strong> the involved<br />

portion <strong>of</strong> the lung without evidence <strong>of</strong> recurrent ITP.<br />

DISCUSSION: In patients with ITP and cancer, cancer-related ITP needs to be considered. However,<br />

limited evidence exists for an extensive investigation for a present or future cancer unless there is high<br />

suspicion <strong>of</strong> malignancy. The possibility <strong>of</strong> paraneoplastic autoimmune thrombocytopenia in<br />

solid tumors may provide further guidance into future immune based therapy.<br />

Toxicity from 33rd element <strong>of</strong> periodic table- The Hair spoke the truth.<br />

Nayan Desai Menon Divya, Harooz Rachel and Gable Brian<br />

INTRODUCTION: Arsenic is one <strong>of</strong> the oldest poisons known to man. Its applications throughout history<br />

are wide and varied, as it has been used in poisons, make-up, paint and pesticide. The following case<br />

report describes a Pakistani male who presented with subacute bilateral progressive ascending<br />

polyneuropathy with respiratory failure and pancytopenia. On subsequent evaluation his condition was<br />

attributed to arsenic, as high levels were present in both hair and urine.<br />

CASE PRESENTATION: A 23 years old Pakistani male presented with a 3-week history <strong>of</strong> bilateral lower<br />

limb paraesthesias. On examination he had absent ankle reflexes with significant sensory deficits to all<br />

modalities below the knees. His complete blood count showed pancytopenia. During the hospital course<br />

he developed progressive ascending weakness <strong>of</strong> the lower extremities, which then spread to upper<br />

extremities over 3 days. He subsequently developed type 2 respiratory failure requiring intubation and<br />

mechanical ventilation. Nerve conduction studies were consistent with sensorimotor axonal<br />

polyneuropathy. An extensive investigation for rheumatologic disorders, familial amyloidosis,<br />

porphyrias, hepatitis, lyme disease, vitamin deficiencies and Gullian barre syndrome were negative.<br />

Bone marrow aspirate with biopsy for the pancytopenia showed severely dysplastic erythropoiesis and<br />

megakaryopoesis. The differential diagnosis at that time was narrowed down to heavy metal<br />

intoxication. On further inquiry it was found that patient experienced the onset <strong>of</strong> these symptoms after<br />

returning from Pakistan four months prior to presentation. Segmental Hair analysis by mass<br />

spectroscopy was positive for arsenic in all 7 segments <strong>of</strong> the hair sample. This represented exposure<br />

over a period <strong>of</strong> more than three months assuming the rate <strong>of</strong> hair growth is 1.25 cm/month. Urinary<br />

arsenic levels were elevated. Marked improvement in clinical features were noted after chelating with<br />

dimercaprol for 48 hours followed by oral succimer. A detailed investigation was done for source <strong>of</strong><br />

arsenic, but no source was found. A hypothesis <strong>of</strong> possible arsenic ingestion from unani medicine for<br />

depression during his stay in Pakistan was postulated but never confirmed.<br />

DISCUSSION: Arsenic toxicity is a global environmental health problem, affecting millions <strong>of</strong> people.<br />

Arsenic induced genotoxicity involve an alteration <strong>of</strong> the integrity <strong>of</strong> the cellular genetic material by<br />

oxidants or free radical species. Acute arsenic poisoning is easily confused with acute diarrhea<br />

associated with cholera. Chronic arsenic intoxication may lead to severe multisystem illness as seen in<br />

this patient and may involve the integumentary, hematological, cardiovascular and peripheral nervous<br />

systems. The neuropathy is primarily due to destruction <strong>of</strong> axonal cylinders and compositional changes,<br />

leading to axonopathy.<br />

This case highlights importance <strong>of</strong> suspecting heavy metal intoxication in patients with multisystem<br />

illness that is not consistent with an alternative classical disease presentation.<br />

A rare cause <strong>of</strong> acute coronary syndrome: Spontaneous coronary dissection<br />

Parag A Chevli, MD Additional authors: Srihari Penkulinti, Kelash<br />

INTRODUCTION: CASE PRESENTATION: A 37 year old Latino female presented with midsternal and<br />

left sided chest pain started 2 days prior to admission. She described the pain as pressure like, 9/10 in<br />

intensity, intermittent, radiating to back, relieved by rest, not associated with exertion or food intake.<br />

The pain was associated with shortness <strong>of</strong> breath, palpitation and light headedness. She denied any<br />

history <strong>of</strong> recent travelling or use <strong>of</strong> birth control pills. Her past medical history was significant for<br />

depression diagnosed 2 years ago for which she was taking citalopram, buspirone and trazodone. She<br />

had regular monthly periods and denied any recent pregnancy. (G1P1A0). There was no family history <strong>of</strong><br />

early/sudden cardiac death. She denied any toxic habits. On examination vitals were stable and physical<br />

examination did not reveal any abnormalities. The electrocardiogram(ECG) revealed Q waves in lead II,<br />

III, aVF, V4-V6. The cardiac troponin I was 0.06(Normal range

Recurrent Cushing<br />

Tatiana Gandrabura, MD Rendy Tomasulo,MD Intekhab Ahmed,MD, FACP<br />

INTRODUCTION: Cushing syndrome and Cushing disease are rare but well-established endocrine<br />

entities. We present a case where our patient had both conditions over a 9-year period.<br />

CASE PRESENTATION: In 2003 a 35-year old female with recent history <strong>of</strong> weight gain, abdominal<br />

striae, easy bruising and abdominal pain underwent an abdominal CT which showed a left-sided adrenal<br />

adenoma measuring 2.5 cm. Work-up to assess the functionality <strong>of</strong> the adenoma revealed an AM<br />

cortisol <strong>of</strong> 30.9 mcg/dL, cortisol <strong>of</strong> 22 mcg/dL after a 1-mg overnight dexamethasone suppression test<br />

(DST), a 24-hour urinary free cortisol (UFC) <strong>of</strong> 1500 mg/dL and an ACTH <strong>of</strong> 213 pmol/L. Magnetic<br />

resonance imaging (MRI) <strong>of</strong> the pituitary revealed a 7-mm right-sided pituitary mass. She underwent<br />

transphenoidal removal <strong>of</strong> her pituitary microadenoma with a dramatic fall in cortisol level to 2 mcg/dL.<br />

She remained in remission until 2011 when her symptoms recurred. Further testing revealed AM cortisol<br />

<strong>of</strong> 24 mcg/dL, cortisol <strong>of</strong> 20 mcg/dL after 1-mg DST, 24 hour UFC <strong>of</strong> 455 mg/dL, and an undetectable<br />

ACTH on more than three occasions. Computed tomography <strong>of</strong> her adrenals showed a left-sided<br />

adrenal adenoma <strong>of</strong> 3.4 cm. MRI <strong>of</strong> the pituitary was unremarkable. She underwent left adrenalectomy<br />

with normalization <strong>of</strong> her biochemical and phenotypic appearance. She is stable on 15mg <strong>of</strong> prednisone<br />

since her surgery.<br />

DISCUSSION: Our case illustrates a very rare presentation <strong>of</strong> recurrent hypercortisolism initially caused<br />

by Cushing disease followed by recurrence <strong>of</strong> hypercortsolism due to Cushing Syndrome.<br />

Cushing disease and Cushing syndrome are well-documented entities; their true incidence remains<br />

imprecise due to the rarity <strong>of</strong> their occurrence. In addition, there is only one case in literature where<br />

both entities were present in the same patient. ACTH-dependent Cushing disease is 5-6 times more<br />

common than ACTH-independent Cushing syndrome.<br />

Most cases <strong>of</strong> hypercortisolism have well-established signs and symptoms. Rarely, sudden onset <strong>of</strong><br />

diabetes, easy bruising or osteoporotic fracture in a young patient may lead to the diagnosis. Gradual<br />

onset <strong>of</strong> central obesity, moon facies, buffalo hump, proximal muscle weakness and atrophy gives the<br />

appearance <strong>of</strong> “lemon on match sticks”. Easy bruising and purple striae on the abdomen and inner<br />

thighs are pathognomonic <strong>of</strong> hypercortisolism.<br />

Diagnosing hypercortisolism is a daunting task. After excluding exogenous glucocorticoid exposure, the<br />

first step is to establish hypercortisolism by 24-hour UFC measurement (most common) or by 1-mg DST.<br />

To differentiate Cushing Disease from Cushing syndrome, an elevated ACTH level favors a pituitary<br />

etiology or ectopic ACTH source, while a suppressed ACTH level favors an adrenal source <strong>of</strong><br />

hypercortisolism. Pituitary MRI helps localize a microadenoma while abdominal computed tomography<br />

helps localize adrenal adenomas. For ectopic source <strong>of</strong> ACTH, chest computed tomography is the initial<br />

investigation. Surgical cure is the best option in majority <strong>of</strong> hypercortisolism cases.<br />

Sacral insufficiency fractures.<br />

Tatiana Gandrabura, MD Randy Tomasulo,MD Intekhab Ahmed,MD,FACP<br />

INTRODUCTION: Sacral insufficiency fractures (SIFs) generally occur in postmenopausal patients with<br />

osteoporosis, those who are undergoing radiation therapy for treatment <strong>of</strong> pelvic malignancy or in<br />

patients treated with high doses <strong>of</strong> corticosteroids. We report a case <strong>of</strong> SIFs in a young female.<br />

CASE PRESENTATION: An 18-year old white female, no prior health issues, presented with low back<br />

pain for six months. Initially the pain was only present during exercise, but eventually it occurred while<br />

walking, rising from chair and rolling over in bed at night. There was no history <strong>of</strong> physical trauma or<br />

family history <strong>of</strong> any skeletal or systemic disorder. She denied alcohol or illicit drug use. Her dairy<br />

consumption was adequate. Her menarche began at age 13 with regular menses and no pregnancies.<br />

On examination her height was 5’ 3”, weight 123 pounds with fair skin. No kyphosis or lordosis was<br />

noted. She reported pain on sitting, rising from a chair, and standing with worsening <strong>of</strong> pain by lumbar<br />

flexion. Her neurological exam for muscle strength and deep tendon reflexes was normal. Serum<br />

calcium was 9.8 mg/dL, intact PTH was 15 pg/mL, 25-hydroxy Vitamin D was 32ng/dL, albumin was 3.9<br />

g/dL, TSH was 1.7 uIU/mL, Complete blood count, renal and hepatic function tests were normal. No<br />

osteopenia or compression fractures were seen on lumbar spine radiographs.<br />

Magnetic resonance imaging <strong>of</strong> the hips showed areas <strong>of</strong> marrow edema within the sacral wings, the<br />

distribution and appearance <strong>of</strong> which was consistent with bilateral SIFs. Bone densitometry using<br />

pediatric s<strong>of</strong>tware showed lumbar bone mineral density Z-score <strong>of</strong> minus 2.1.<br />

DISCUSSION: SIFs are a form <strong>of</strong> stress fractures caused by normal stress applied to bone with deficient<br />

elastic resistance. Osteoporosis is the most important cause <strong>of</strong> SIFs, followed by high dose steroid<br />

therapy. Low back and buttock pain exacerbated by movement is the most common presentation.<br />

Patients may also have other fractures such as pubic ramus fracture. A technetium-99 bone scan may<br />

show the classic “H” or “Honda” sign representing combined bilateral vertical and horizontal sacral<br />

fractures in 15–68% cases. Magnetic resonance imaging demonstrates bone marrow edema. Computed<br />

tomography <strong>of</strong> the lumbar spine is considered the gold standard for diagnosis. Evaluation includes<br />

serum 25-hydroxy vitamin D, calcium levels, and work-up for secondary causes <strong>of</strong> osteoporosis. Bed rest<br />

in the acute phase (up to 72 hours) is <strong>of</strong>ten recommended, though there is beneficial evidence <strong>of</strong> early<br />

mobilization. Acetaminophen and anti-inflammatories are used for pain. Older patients may benefit<br />

from bisphosphonate use. Calcium and vitamin D supplementation is recommended along with<br />

pharmacotherapy. Sacroplasty may be an option for relief <strong>of</strong> chronic pain.<br />

Sarcoidosis: not always restrictive!<br />

Vipin Mittal, MBBS Co-Authors: Anery Patel, MD Medhat Ismail, MD.<br />

INTRODUCTION:Sarcoidosis is a multisystem granulomatous disorder <strong>of</strong> unknown etiology that is<br />

characterized pathologically by the presence <strong>of</strong> non-caseating granulomas in involved organs. It initially<br />

presents with either bilateral hilar adenopathy or pulmonary reticular opacities or skin, joint and/or eye<br />

lesions. Pulmonary function tests characteristically reveal a restrictive pattern with a reduction in the<br />

diffusing capacity for carbon monoxide, although it is not unusual for lung function to be normal.<br />

CASE PRESENTATION: 47 year old African-<strong>American</strong> female who has past medical history significant<br />

for COPD, severe pulmonary hypertension with pulmonary arterial pressure <strong>of</strong> approx. 87mm Hg with<br />

resultant right sided heart failure, cirrhosis <strong>of</strong> liver, and ascites presented in Emergency room with<br />

progressively worsening cough, shortness <strong>of</strong> breath for 2 weeks. (The symptoms <strong>of</strong> mild cough and<br />

shortness <strong>of</strong> breath were present for almost two years.) She has been on spironolactone, furosemide,<br />

digoxin, baby aspirin and fluticasone inhaler at home. She denied smoking, alcohol, illicit drug use and<br />

occupational exposures. She had temperature <strong>of</strong> 97 F, pulse rate <strong>of</strong> 94 bpm, blood pressure <strong>of</strong> 115/87<br />

mmHg, and respiratory rate <strong>of</strong> 18 per minute. On physical exam she had distended neck veins,<br />

diminished vesicular breath sounds, bilateral scattered rales, normal S1 and accentuated S2, distended<br />

abdomen, ascites, firm liver and minimal edema in bilateral lower extremities. Laboratory data<br />

was significant for mild anemia, elevated B type natriuretic peptide level (1910 pg/ml; normal range 0-<br />

100). Serum chemistry, alpha 1 antitrypsin, ACE (angiotensin converting enzyme) level was normal. HIV<br />

& Hepatitis pr<strong>of</strong>ile was negative. Chest radiograph showed chronic fibrotic changes with hyperinflation.<br />

CT scan <strong>of</strong> the chest revealed diffuse emphysematous changes, retico-nodular fibrotic changes in<br />

bilateral upper lobes. Patient was admitted and started on sildenafil and diuretics and intravenous<br />

solumedrol. Pulmonary function tests revealed low FEV1 (34% <strong>of</strong> predicted), low FVC (55% <strong>of</strong> predicted)<br />

with a moderate reduction in FEV1 /FVC ratio (63% <strong>of</strong> predicted) consistent with obstructive<br />

pattern. Residual volume was estimated to be very high (115%). Diffusion capacity was also found to be<br />

severely reduced (30% <strong>of</strong> predicted) consistent with severe pulmonary hypertension and radiological<br />

findings. Video assisted thoracic surgery (VATS) for lung biopsy was scheduled to rule out the possibility<br />

<strong>of</strong> Lymphangiomyomatosis (LAM). The pathology revealed non-caseating granulomas in all sections <strong>of</strong><br />

lung biopsy with areas <strong>of</strong> atelectatic and emphysematous changes. Diagnosis <strong>of</strong> sarcoidosis was<br />

confirmed and patient was discharged home on steroids resulting in a good response.<br />

DISCUSSION: We present a patient who had chronic lung disease <strong>of</strong> unclear etiology that led to a<br />

number <strong>of</strong> sequels from resultant right sided heart failure. The diagnosis <strong>of</strong> sarcoidosis can be<br />

challenging in he absence <strong>of</strong> typical presentation. The diagnosis is based upon clinical and radiological<br />

findings, exclusion <strong>of</strong> other diseases that may present similarly and histopathologic evidence <strong>of</strong> noncaseating<br />

granulomas. It is rare for sarcoidosis to manifest as emphysematous changes and obstructive<br />

pattern on pulmonary function tests. Hence, lung biopsy is the only definitive answer in such cases.<br />

INTRODUCTION:Mycotic aneurysm is a localized, irreversible arterial dilatation due to destruction <strong>of</strong><br />

the vessel wall by infection. It can develop as a complication <strong>of</strong> bacterial endocarditis and should be kept<br />

in differential diagnosis.<br />

CASE PRESENTATION: A 26 year-old male came to the hospital with the chief complaint <strong>of</strong> epigastric<br />

pain <strong>of</strong> one month duration. It was sharp, constant, 9/10 in intensity, non-radiating and with minimal<br />

relief with over the counter pain medications. He had no significant past medical or surgical history. He<br />

has been an active intravenous heroin abuser, smoked half a pack <strong>of</strong> cigarettes per day and drank<br />

alcohol on daily basis. On examination, he had fever (102°F), tenderness in the epigastric region and a<br />

diastolic murmur. The diagnosis <strong>of</strong> infective endocarditis was made and he was started on broad<br />

spectrum antibiotics. Computed tomography (CT) scan abdomen revealed splenic infarct, bilateral renal<br />

infarcts and a bi-lobed fusiform superior mesenteric artery aneurysm (SMAA) distal to its origin<br />

measuring about 5.7 cm in its greatest dimension. Echocardiogram showed aortic valve vegetation<br />

measuring 4.4 x 1.1 cms with severe aortic valve regurgitation. Blood cultures grew Enterococcus<br />

faecalis group D organisms. The patient also developed an embolic stroke involving the right middle<br />

cerebral artery and had left-sided hemiplegia. Subsequently, he complained <strong>of</strong> worsening abdominal<br />

pain and on examination had a pulsatile swelling in the epigastrium. Repeat CT scan <strong>of</strong> the abdomen<br />

showed increase in the size <strong>of</strong> the superior mesenteric artery aneurysm measuring 7.6 x 6.7 x 7.6 cm. An<br />

aortogram was obtained which showed a pseudoaneurysm involving superior mesenteric artery beyond<br />

jejunal and ileal branches and measured about 9 cm. Ultrasound guided fibrin injection <strong>of</strong> the aneurysm<br />

was tried with only partial thrombosis. Eventually, the patient went for exploratory laparotomy and<br />

ligation <strong>of</strong> the pseudoaneurysm. He also underwent aortic valve replacement and was discharged to a<br />

rehabilitation center.<br />

DISCUSSION: Mycotic aneurysm can develop following bacterial infection <strong>of</strong> a previously normal<br />

arterial wall or through secondary infection <strong>of</strong> a preexisting aneurysm. This case illustrates development<br />

<strong>of</strong> mycotic aneurysm as a complication <strong>of</strong> bacterial endocarditis. Possible mechanisms include occlusion<br />

<strong>of</strong> vasa vasorum or entire arterial lumen by tiny septic emboli, damaging the muscular layer <strong>of</strong> the<br />

vessel, and subsequent intra-arterial pressure causing dilation and aneurysm formation. SMAAs have a<br />

definite rupture risk and high resultant mortality. Early recognition <strong>of</strong> this complication is important for<br />

appropriate treatment and prevention <strong>of</strong> further complications.<br />

SUDDEN CARDIAC DEATH AS A PRESENTATION OF ANOMAOLUS ORIGIN OF THE LEFT CORONARY<br />

ARTERY FROM PULMONARY ARTERY IN A YOUNG ADULT<br />

Ronald E Pachon, MD Co-Authors: Mark Niemiera, MD, FACC; Constante Gil, MD FACP; Shuvendu Sen,<br />

MD; Vishwanath Pattan, MD; Kebir Bedran, MD; Fowad Shahzad,MD<br />

INTRODUCTION: Sudden cardiac death in itself is a rarity in young adults in the absence <strong>of</strong><br />

hypertrophic cardiomyopathy. Congenital cardiac anomalies presenting as sudden cardiac death in<br />

adulthood without any preceding symptoms in childhood are extremely rare (1). We report a case<br />

<strong>of</strong> sudden cardiac death as the first presentation <strong>of</strong> anomalous origin <strong>of</strong> the left coronary artery from<br />

pulmonary artery (ALCAPA) in a young female with no history <strong>of</strong> hypertrophic cardiomyopathy.<br />

CASE PRESENTATION: An 18 year-old apparently healthy and physically active female, who was last<br />

seen competitively running 4 min prior, was found to be unresponsive. A paramedic at the site, who<br />

found her pulseless, performed CPR until EMS team cardioverted and intubated her on arrival 5 min<br />

later. In the ED vital signs revealed BP: 126/100 mmHg, HR: 172 BPM, RR: 20/min, Tº: 98.7ºF. Her family<br />

reported a flu-like illness one week before admission but denied any episodes <strong>of</strong> cyanosis, palpitation,<br />

joint swelling or skin lesions in the remote past. They denied patient history <strong>of</strong> trauma, recent travel,<br />

smoking, drugs, alcohol, medication use or any family history <strong>of</strong> sudden cardiac death. On examination<br />

the patient was intubated and appeared pale without cyanosis, JVD, or carotid bruit; she had regular<br />

heart sounds with no murmur, rub or gallop. The rest <strong>of</strong> physical examination was unremarkable. ECG<br />

showed sinus tachycardia with T wave inversions in leads I, aVL and V1-V4, QTc 421 ms; CXR showed no<br />

evidence <strong>of</strong> pneumothorax, enlarged mediastinum or pleural effusion. Chest CT angiogram did not<br />

reveal any evidence <strong>of</strong> pulmonary embolism. Head CT scan showed no evidence <strong>of</strong> hemorrhage. Urine<br />

drug and pregnancy screens were negative. CBC and metabolic panel were within normal limits.<br />

Complement levels were normal. Serial troponin I (0.36, 7.39) and CKMB (5.69, 216) were elevated.<br />

Echocardiography showed severely impaired EF (20%) with a hypokinetic LV without any evidence <strong>of</strong><br />

significant valvular or hypertrophic heart disease. She was immediately transferred to a tertiary center<br />

for cardiac catheterization which showed ALCAPA. Unfortunately the patient had irreversible brain<br />

damage due to anoxic encephalopathy and no further intervention was pursued.<br />

DISCUSSION: The patient had collateral circulation from her RCA to LAD which likely enabled her to be<br />

physically active without any symptoms until the day <strong>of</strong> presentation. This clinical case illustrates the<br />

need for early consideration and recognition <strong>of</strong> ALCAPA in otherwise healthy young individual, who<br />

presents with sudden cardiac death.<br />

SALEH MD<br />

INTRODUCTION:Seizure Disorder has varied differential diagnosis. But when it is combined with a<br />

specific electrolyte abnormality and a specific computed tomography finding, then the diagnosis<br />

narrows down to a few rare causes. In this case report we present to you a case <strong>of</strong> seizure disorder with<br />

underlying pseudohypoparathyroidism in a patient <strong>of</strong> Fahr’s Syndrome.<br />

CASE PRESENTATION: 18 year old Indian female presented with 3 episodes <strong>of</strong> generalized tonic clonic<br />

seizures over the preceding 24 hours. On further inquiry patient’s family observed that she had been<br />

drowsy, had multiple episodes <strong>of</strong> vomiting and was extremely lethargic since 10 days. She had a history<br />

<strong>of</strong> Seizure disorder, which was diagnosed 4 years prior to presentation and was refractory to medical<br />

therapy with phenytoin, phenobarbitone and valproic acid for the same. She denied any history <strong>of</strong><br />

recent trauma to the head, fever or photophobia.<br />

On examination, she was afebrile with a heart rate <strong>of</strong> 94 bpm, blood pressure <strong>of</strong> 120/84 mm <strong>of</strong> mercury.<br />

On Central nervous system examination patient was drowsy, responding to painful stimuli. Deep tendon<br />

reflexes were 3+ in all extremities. Examination <strong>of</strong> the other systems was essentially within normal<br />

limits. Investigations were suggestive <strong>of</strong> hypocalcemia (Ca-6.5 mg/dl) and hyperphosphatemia<br />

(Phosphorus- 6.1 mg/dl). Her renal function test, liver function test and 25 Vitamin D levels were within<br />

range. Computerised tomography scan <strong>of</strong> the head showed diffuse calcification <strong>of</strong> the Basal Ganglia<br />

bilaterally. Parathyroid hormone levels were elevated. So a diagnosis <strong>of</strong> Fahr’s syndrome with<br />

pseudohypoparathyroidism was made. Patient was started on oral calcium supplementation along with<br />

calcitriol. Patient calcium and phosphorus normalized after 4-6 weeks <strong>of</strong> treatment and patient<br />

remained symptom free.<br />

DISCUSSION: Fahr's Syndrome is a rare, genetically dominant, inherited neurological disorder<br />

characterized by abnormal deposits <strong>of</strong> calcium in areas <strong>of</strong> the brain that control movement, including<br />

the basal ganglia and the cerebral cortex. Symptoms <strong>of</strong> the disorder may include deterioration <strong>of</strong> motor<br />

function, dementia, seizures, headache, dysarthria, spasticity.Age <strong>of</strong> onset is typically in the 40s or 50s,<br />

although it can occur at any time in childhood or adolescence. When it is associated with<br />

pseudohypoparathyroidism, management will mainly be focused towards optimizing Serum Calcium<br />

levels towards with the help <strong>of</strong> Calcium, Vitamin D supplements and Calcitriol.<br />

INTRODUCTION:Oral ulcers are common in HIV patients, differential <strong>of</strong> which varies from viral,<br />

bacterial, fungal, mycobacterial to neoplastic causes.In some countries other than the United States,<br />

although definite sub-typing based on geography for fungal infection is lacking, fungal infections are<br />

indeed common opportunistic pathogens in AIDS patients. The purpose <strong>of</strong> this case is to sensitise<br />

physicians towards fungal infections to be considered as a part <strong>of</strong> the differential diagnosis in immigrant<br />

populations <strong>of</strong> AIDS patients who present with clinical features <strong>of</strong> fever, lymphadenopathy and weight<br />

loss.<br />

CASE PRESENTATION: A 28 year old married male from India presented with painful ulcer at the left<br />

angle <strong>of</strong> his mouth present for 2 months which resulted in severe pain on deglutition.The ulcer gradually<br />

increased in size and spread over the left buccal mucosa. Patient also noticed a progressive enlarging<br />

swelling in the left submandibular region.He complained <strong>of</strong> low grade fever, loss <strong>of</strong> appetite and weight<br />

loss <strong>of</strong> 6 kg in the preceding 2 months.<br />

On inquiry, patient was known to be HIV 1 positive for the past 1 year and not on any antiretroviral<br />

drugs. Patient was started on antitubercular 4 drug regimen for last 1 month after fine needle aspiration<br />

cytology <strong>of</strong> left submandibular swelling from a different hospital.However patients symptoms continued<br />

to worsen inspite <strong>of</strong> being on treatment.<br />

On examination, weight was 49 kg with poor nutritional status, oral temperature <strong>of</strong> 37.8 C, pulse <strong>of</strong> 130<br />

bpm and blood pressure <strong>of</strong> 110/74 mm <strong>of</strong> mercury. Local examination revealed an irregular tender,<br />

indurated ulcer at left angle <strong>of</strong> mouth covered with pus and slough. Left submandibular lymph node was<br />

discrete 3 X 3 cm tender, firm and freely mobile.No axillary and inguinal lymphadenopathy.Nontender<br />

hepatosplenomegaly was present.<br />

Scrapings were taken from the oral ulcer and a biopsy <strong>of</strong> submandibular swelling was performed.<br />

Histopathological examination <strong>of</strong> stained smear showed epitheloid granulomas with intracellular<br />

granules classic <strong>of</strong> Histoplasma capsulatum. Special stain with Gomori methnamine silver stain<br />

confirmed the findings.<br />

A diagnosis <strong>of</strong> AIDS with disseminated histoplasmosis was made.Antitubercular drugs were stopped and<br />

patient was started on intravenous amphotericin B for 25 days followed by maintainence therapy with<br />

itraconazole for 12 weeks. Marked clinical improvement along with reduction in ulcer size by 70% was<br />

noted.<br />

DISCUSSION: This case highlights the fact that although tuberculosis is the most common opportunistic<br />

pathogen in AIDS patients in developing countries and immigrant populations,fungal infections like<br />

histoplasmosis share many clinical features with constitutional symptoms,lymphadenopathy and<br />

multiorgan involvement and hence should always be included in the differential diagnosis.<br />

Demonstration <strong>of</strong> organisms in biopsy samples are crucial in the confirmation <strong>of</strong> a definitive diagnosis<br />

and treatment.<br />

Persistent Vertigo As A Presentation Of Pulmonary Leptomeningeal Carcinomatosis<br />

Yue Cindy Wang, MD, Brain H Kim, MD<br />

INTRODUCTION: Leptomeningeal carcinomatosis (LMC) is an uncommon manifestation <strong>of</strong> metastatic<br />

lung cancer. The overall incidence reported is 3-8%. Diagnosis is <strong>of</strong>ten difficult to establish. We report<br />

a rare case <strong>of</strong> LMC from recurrent lung cancer that presented initially with persistent vertigo.<br />

CASE PRESENTATION: A 73-year-old female presented to the emergency room with persistent<br />

vertigo. One month prior to this admission, she developed sudden onset <strong>of</strong> vertigo associated with<br />

nausea, bilateral tinnitus and some unsteady gait. Patient came to ER twice and was admitted to the<br />

hospital on the 2 nd visit. Physical examination and laboratory tests were essentially normal. Brain CT,<br />

MRI and MRA showed no evidence <strong>of</strong> stroke, mass or vascular insufficiency. She was diagnosed with<br />

peripheral vertigo and discharged with meclizine and methylprednisolone. However, her symptoms<br />

persisted. She was referred to ENT and the examination was negative. Patient returned with<br />

unresolving vertigo and new-onset dysphagia. Her past medical history is significant for early stage lung<br />

adenocarcinoma diagnosed in 2006. She had left lower lobectomy without chemotherapy or<br />

radiotherapy. She followed up with her oncologist every three months and there was no clinical or<br />

imaging evidence <strong>of</strong> recurrence. Patient was readmitted for further investigation. Physical examination<br />

and laboratory tests were unremarkable. A barium esophagogram done to evaluate the patient for<br />

dysphagia was noncontributory. A repeated brain MRI, however, demonstrated innumerable foci <strong>of</strong><br />

leptomeningeal carcinomatosis involving cranial nerves V, VIII, and XII. CSF cytology was sent and<br />

positive for marked atypical cells, consistent with metastatic adenocarcinoma. CT chest revealed<br />

conglomerate mediastinal adenopathy with the largest measuring 1.7cm. Ultrasound guided FNA <strong>of</strong> a<br />

mediastinal node confirmed lung adenocarcinoma. Patient deferred further treatment and was<br />

discharged to hospice.<br />

DISCUSSION: LMC is characterized by a diffuse infiltration <strong>of</strong> neoplastic cells to the<br />

leptomeninges. The clinical presentation is heterogeneous with involvement <strong>of</strong> cerebrum, cranial<br />

nerves and spinal cord. Diagnosing LMC can be challenging. MRI, commonly regarded as the imaging<br />

study <strong>of</strong> choice, has a sensitivity <strong>of</strong> 66-77%. Cytology <strong>of</strong> CSF is the gold standard, but still misses about<br />

10% <strong>of</strong> the cases. The prognosis <strong>of</strong> LMC is dismal. Early diagnosis and therapy is crucial to preserving<br />

neurological function, relieving symptoms and improving survival. Currently, intrathecal chemotherapy<br />

remains the mainstay <strong>of</strong> treatment although survival benefit is still in debate.<br />

Isolated vertigo is an unusual presentation <strong>of</strong> LMC, not necessarily associated with a known history <strong>of</strong><br />

malignancy. In our case, the nonspecific symptoms, normal physical and initial negative imaging led to a<br />

delay in doing CSF cytology. A high index <strong>of</strong> suspicion and early CSF analysis are warranted for accurate<br />

diagnosis.<br />

Vibrio Vulnificus infection in New Jersey after Hurricane Irene<br />

Sumeja Zahirovic, MD Authors: Min J. Kim, MD, Harry A. Roselle MD, FACP<br />

INTRODUCTION: Vibrio Vulnificus is a gram-negative bacillus inhabiting warm salt water environments.<br />

Infection occurs by ingestion <strong>of</strong> uncooked seafood, or exposure <strong>of</strong> skin wound to infected waters.<br />

Patients with liver disease, depressed immune response, and hemochromatosis are at a particular risk <strong>of</strong><br />

developing the infection with necrotizing fasciitis and septic shock. The presence <strong>of</strong> shock increases<br />

mortality to greater than 50%. The majority <strong>of</strong> the cases occur in the Gulf Coast states. According to<br />

New Jersey Department <strong>of</strong> Health and Senior Services (NJDHSS), approximately 12 cases <strong>of</strong> non-cholera<br />

vibriosis are reported annually in New Jersey. We present a patient with Vibrio Vulnificus infection, who<br />

frequented the beach <strong>of</strong> Jersey shore as a runner.<br />

CASE PRESENTATION: An 82-year-old runner with psoriatic arthritis on prednisone presented with<br />

severe right lower extremity pain and swelling. He developed nausea, vomiting and lethargy, which<br />

prompted his family to bring him to the hospital. He had a fever <strong>of</strong> 100.7 F, blood pressure 72/43 mmHg,<br />

and pulse rate 77 beats/minute. Physical examination revealed edema, erythema, warmth, tenderness,<br />

and blisters <strong>of</strong> right lower extremity. Laboratory studies were significant for WBC 16400/uL and 7.5<br />

mg/dL <strong>of</strong> lactic acid. The patient was transferred to ICU for septic shock secondary to presumptive<br />

cellulitis, where he developed toxic encephalopathy and acute respiratory failure, requiring mechanical<br />

ventilation. He received aggressive intravenous hydration, pressors, stress dose <strong>of</strong> hydrocortisone and<br />

broad-spectrum antibiotics. His condition did not improve and he developed rhabdomyolysis, metabolic<br />

acidosis and acute renal failure. He was taken for extensive surgical debridement from ankle to knee.<br />

The pathology was consistent with necrotizing fasciitis. Blood and wound cultures grew Vibrio Vulnificus;<br />

hence, empiric antibiotics were changed to cefepime, clindamycin and doxycyclin. He became<br />

hemodialysis dependent due to renal failure with anuria. He was extubated, but still required high flow<br />

oxygen. He developed acute gastrointestinal bleeding, and was found to have ferritin <strong>of</strong> more than<br />

20000 ng/mL. Further workup for hemochromatosis was deferred due to his unstable condition. DNR<br />

was requested. After about 2 weeks <strong>of</strong> ICU stay, patient had asystolic cardiac arrest. Autopsy was<br />

refused by his family.<br />

DISCUSSION: We report a patient with psoriatic arthritis, chronic prednisone treatment, and possible<br />

hemochromatosis, who developed Vibrio Vulnificus septicemia at the Jersey Shore. He developed the<br />

infection soon after Hurricane Irene. An increased incidence <strong>of</strong> Vibrio Vulnificus infection has been<br />

reported after Hurricane Katrina secondary to flooding with infected waters. Suspicion <strong>of</strong> Vibrio<br />

Vulnificus in New Jersey should be raised in patients with severe cellulitic features, especially following a<br />

tropical storm, which may lead to an early diagnosis, proper management, and improved mortality.<br />

Chapter Winning Abstract - A Malignant Metabolic Disturbance: Lactic Acidosis And Hypoglycemia In A<br />

66 Y.O. Navajo Female.<br />

Jonathan Jivin Danaraj, DO Second Author: Michelle Harkins, MD<br />

INTRODUCTION: The presentation <strong>of</strong> hypoglycemia and lactic acidosis in a patient with diffuse large B<br />

cell lymphoma is extremely rare. There are approximately 30 described cases <strong>of</strong> lactic acidosis in<br />

association with lymphoma and fewer that include hypoglycemia. This constellation <strong>of</strong> findings leads to<br />

a poor prognosis.<br />

CASE PRESENTATION: A 66 y.o. female with history <strong>of</strong> DM II was transferred from an outside hospital<br />

(OSH) to The University <strong>of</strong> New Mexico Hospital(UNMH) after ct scan to rule out pulmonary embolus<br />

found mediastinal lymphadenopathy suspicious for lymphoma. The patient had presented to her pcp<br />

two weeks prior with mild malaise. Labs from OSH revealed a leukocytosis <strong>of</strong> 33,000 with a lymphocyte<br />

predominance 40% on peripheral smear, an anion gap acidosis , and hypoglycemia to 27. Initially, the<br />

patient was mildly tachycardic but otherwise hemodynamically stable. Repeat labs confirmed the<br />

leukocytosis with lymphocyte predominance and illustrated a mild liver failure. Specific labs included a<br />

anion gap <strong>of</strong> 23, uric acid <strong>of</strong> 14.8, ldh <strong>of</strong> 3884, lactate <strong>of</strong> 10, potassium was 3.4, phosphate was 3.3 and<br />

glucose <strong>of</strong> 54. A bone marrow biopsy and flow cytometry revealed atypical, CD20+ lymphocytes with<br />

distinct vacuoles and large indented nuclei. These findings made diffuse large b-cell lymphoma most<br />

likely. Lymph node architecture from biopsy was not possible as the patient deteriorated clinically. On<br />

hospital day 2, the lactic acidosis had not improved and her urine output dwindled. Her pH on ABG<br />

was 7.12. The patient’s hypoglycemia was difficult to control in the low 90’s with a d5w infusion. The<br />

patient further decompensated requiring pressors and was intubated for respiratory<br />

failure. Chemotherapy was initiated with cyclophosphamide and rituxan. On hospital day 3, the patient<br />

had increased pressor requirements and further increase <strong>of</strong> lactate to 21 and an ABG pH <strong>of</strong> < 6.8. The<br />

patient became anuric. Care was withdrawn shortly after and the pt expired.<br />

DISCUSSION: These metabolic abnormalities when attributed to lymphoma have described mortality<br />

rates >70% occuring within weeks to one month. These alarming statistics have some oncologists<br />

suggesting this to be an oncologic emergency. The pathophysiology <strong>of</strong> these findings occur when there<br />

is a high tumor burden and with diffuse infiltration <strong>of</strong> malignant cells into the liver inhibiting the cori<br />

cycle preventing the body from eliminating lactate and creating glucose. Prompt recognition is crucial as<br />

the rapid progression to multi-organ failure can only be prevented if the malignancy responds to<br />

chemotherapy.<br />

Cesar E Ayala-Rodriguez Samir Garyali<br />

INTRODUCTION: Total occlusion <strong>of</strong> the left main coronary artery (LMCA) is a rare angiographic finding<br />

due to its catastrophic clinical presentation associated with sudden cardiac death, cardiogenic shock,<br />

pulmonary edema or malignant arrhythmias. It has pronounced therapeutic implications with potential<br />

need <strong>of</strong> emergent coronary bypass grafting. Despite moderate accuracy <strong>of</strong> the electrocardiogram (EKG)<br />

to determine the anatomic location <strong>of</strong> infarction, it has the ability to discriminate among various<br />

coronary artery obstruction patterns, ST-segment elevation (STE) in lead aVR, although frequently<br />

overlooked it has been recognized to indicate LMCA occlusion.<br />

CASE PRESENTATION: Case No.1: An 80 year old male presented with retrosternal chest pain,<br />

occurring intermittently for the past 2 weeks but more frequently in the past 3 days. These episodes<br />

would last for 20 minutes and were associated with shortness <strong>of</strong> breath.<br />

PMHx: Three vessel CAD with PCI–RCA stenting 5 months prior and normal LVEF, systemic hypertension<br />

and hypercholesterolemia.<br />

PE: BP=115/75mmHg, HR=105, RR=16, Temp=98.3°F, O2Sat=100%, S1,S2 were audible, tachycardic,<br />

regular rhythm, with no gallop or murmur. Lungs were clear and the rest was unremarkable.<br />

Initial labs: Creatinine 1.3mg/dL, WBC 8.1/dL, hematocrit 38, platelets 277K, CK 160ng/mL and<br />

Troponin-I 0.63ng/mL. LVEF 40%.<br />

Evolution: Developed recurrent episodes <strong>of</strong> ventricular fibrillation and a successfully treated cardiac<br />

arrest. After which coronary arteriography showed 99% stenosis <strong>of</strong> LMCA which was reduced to 0% after<br />

everolimus-eluting stent placement.<br />

Case No.2: A 59 year old female presented with retrosternal pressure-like pain, radiated to left arm, jaw<br />

and upper back, pain persisted until ED management. Symptoms had occurred with less intensity<br />

intermittently for the past 3 days, sometimes at rest and self resolving after minutes. Was detected with<br />

narrow complex tachycardia to 170 bpm by EMS team.<br />

PMHx: Diabetes mellitus type2 for 14 years, systemic hypertension and hypercholesterolemia.<br />

PE: BP=153/69mmHg, HR=119, RR=19, Temp=98.7°F, O2Sat=92% on 4L/min. Lungs with bibasilar rales to<br />

mid lung fields. S1,S2 were audible, tachycardic, regular rhythm, with no gallop or murmur. Rest <strong>of</strong> exam<br />

was unremarkable.<br />

Initial labs: Creatinine 0.7mg/dL, WBC 12.1K/dL, hematocrit 41.8, platelets 308K/dL, CK<br />

42/1.7ng/mL and 90’ 65/5.0ng/mL and Troponin-I 0.08ng/mL and 90’ 0.29ng/mL<br />

Chest Xray revealed bilateral pulmonary congestion, no cardiomegaly.<br />

Evolution: Plavix withheld on initial therapy. After angiogram, on day#2 had emergent <strong>of</strong>f pump<br />

coronary bypass x2 with LIMA to LAD and reverse saphenous vein graft to OM.<br />

375


DISCUSSION: These cases emphasize the importance <strong>of</strong> isolated STE in lead aVR. It has been<br />

demonstrated to indicate LMCA occlusion or severe three-vessel CAD.<br />

The distinction <strong>of</strong> acute coronary syndromes (ACS) with pr<strong>of</strong>ound therapeutic and prognostic<br />

implications is based on the ST-segment. It was established in early fibrinolytic trials that did not<br />

consider isolated STE in analysis.<br />

However the prognostic significance <strong>of</strong> this EKG finding is <strong>of</strong> great magnitude and may play a great role<br />

on survival <strong>of</strong> patients with NSTEMI.<br />

The incidence <strong>of</strong> LMCA occlusion in patients undergoing elective coronary angiography is 0.03-0.04%<br />

and 0.37 to 2.96% in patients with acute myocardial infarction undergoing emergent cardiac<br />

catheterization.<br />

The diagnostic importance <strong>of</strong> STE in aVR in early management <strong>of</strong> ACS is heighten by the determination<br />

<strong>of</strong> thienopyridine use due to potential emergent coronary artery bypass grafting or nowadays<br />

revascularization by stenting.<br />

Much more recognition and further analysis <strong>of</strong> the value <strong>of</strong> STE in aVR in management <strong>of</strong> ACS is needed<br />

to confirm these proposals<br />

Chapter Winning Abstract UNFRACTIONATED HEPARIN INDUCED SKIN NECROSIS<br />

Suneesh Anand,Rawat N,Covalcic C, Dhanve A, Maheshwari N,C Abeddi, Matejak P, Newman T.<br />

INTRODUCTION: Unfractionated heparin (UFH) induced skin necrosis is a rare immune complex<br />

phenomenon associated with heparin induced thrombocytopenia (HIT) syndrome. It is seen in patients<br />

with thrombocytopenia (more than 50% decrease) or less commonly in the presence <strong>of</strong> HIT antibodies<br />

alone. In our patient however there was only mild thrombocytopenia (less than 50% decrease) and<br />

serologies for HIT were negative.<br />

CASE PRESENTATION: 54 year old female with Diabetes Mellitus and Asthma was admitted for two<br />

day history <strong>of</strong> fever, cough and pleuritic chest pain. She was started on antibiotics for community<br />

acquired pneumonia since chest radiograph showed bilateral infiltrates. Atypical pneumonia workup<br />

was positive for influenza A and she was started on treated with Oseltamivir. However she continued to<br />

be febrile and fever work up was initiated. Echocardiogram and Pan Computed Tomography was done<br />

which was inconclusive. Venous duplex showed acute deep vein thrombosis (DVT) in both lower limbs<br />

and she was started on UFH drip. She had already been on DVT prophylaxis with subcutaneous heparin<br />

since admission. Within two days <strong>of</strong> UFH heparin drip, she developed skin lesions on medial aspect <strong>of</strong><br />

right thigh and later on both breasts. The lesions were well demarcated, hyperpigmented, purple<br />

patches with erythematous borders. Work up for Disseminated Intravascular Coagulation,<br />

Antiphospholipid syndrome, Factor V Leiden, Protein C and S, Prothrombin 20210A were unremarkable.<br />

Biopsy was done which showed thrombotic vasculopathy associated with epidermal necrosis and no<br />

evidence <strong>of</strong> vasculitis. Given the clinical presentation and histopathology report, heparin induced skin<br />

necrosis was thought to be the most likely diagnosis. UFH was discontinued and replaced by argatroban<br />

drip and lesions gradually resolved.<br />

DISCUSSION: Eventhough, it is uncommon for UFH induced skin necrosis to occur in the absence <strong>of</strong><br />

thrombocytopenia or HIT antibodies, the diagnosis should be considered with suspicious skin lesions as<br />

in our case. Classically HIT occurs after 3 to 5 days <strong>of</strong> initial dosing, however it can happen earlier in<br />

previously sensitized patient (like our case). The presence <strong>of</strong> such skin lesions should alert the clinician<br />

the risk for systemic thromboembolic events and treatment with alternative thromboprophylactic agent<br />

should be considered<br />

MBChBBAO<br />

INTRODUCTION: In a structurally normal heart ventricular tachycardia may be dismissed as a cause <strong>of</strong><br />

syncope, however, there are exceptions to this rule. We report a rare, life threatening, cause <strong>of</strong><br />

syncope in a structurally normal heart.<br />

CASE PRESENTATION: A 63 year old female with past medical history significant for hypertension and<br />

non cardiac chest pain presented to the emergency department with an episode <strong>of</strong> syncope. While<br />

getting out <strong>of</strong> a hot shower the patient lost consciousness, fell, and hit her head. Her husband heard a<br />

thud and rushed into the bathroom finding his wife unconscious. He checked her pulse and noted it to<br />

be irregular. She regained consciousness within a few minutes and had no recollection <strong>of</strong> the event.<br />

Over the previous several months the patient had multiple episodes <strong>of</strong> lightheadedness which were<br />

evaluated with holter monitoring, an event recorder, nuclear stress test, and transthoracic<br />

echocardiogram in the outpatient settings and found unrevealing. Her physical exam, lab work, cardiac<br />

enzymes, and 24-hour telemetry monitoring were unremarkable.<br />

DISCUSSION: She was discharged home with follow up with a cardiologist. The cardiologist reviewed<br />

her several EKGs that were read as "INCOMPLETE RBBB", "NON SPECIFIC INTRAVENTRICULAR<br />

CONDUCTION DELAY", and "NON SPECIFIC ST-T ABNORMALITY" in leads V1-V2. He also elicited further<br />

family history <strong>of</strong> the patient’s mother passing away in her sleep. This raised the possibility <strong>of</strong> the<br />

Brugada syndrome leading to syncope. The patient underwent an Electrophysiology study which showed<br />

the classic "coved ST pattern" after Ajmaline administration, characteristic <strong>of</strong> type 1 Brugada syndrome.<br />

She was managed with an Implantable Defibrillator, potentially preventing a life threatening event.<br />

Nischala Ammannagari MD , Kathleen Laveaux MD, Sara Grethlein MD, Alfred Cretella MD<br />

INTRODUCTION:Acquired Hemophilia is a rare bleeding disorder caused by autoantibodies against<br />

factor VIII. Association with skin diseases like autoimmune bullous diseases is extremely uncommon. We<br />

present one such rare case <strong>of</strong> acquired factor VIII inhibition in the setting <strong>of</strong> bullous pemphigoid in an<br />

elderly male.<br />

CASE PRESENTATION: A 69-year old Caucasian male with history <strong>of</strong> recurrent blistering skin eruptions<br />

<strong>of</strong> upper extremities (treated with prednisone) presented to our emergency department with worsening<br />

painless and non-pruritic skin blisters and dizziness. At arrival to ER he was found to be hypotensive and<br />

pr<strong>of</strong>oundly anemic (Hemoglobin 7.2 and Hematocrit 21.9). This was down dramatically from a prior<br />

hemoglobin <strong>of</strong> 12.5 two days earlier and 14.7 four days earlier. There was no overt external bleeding, no<br />

trauma, no hemoptysis or hematemesis with negative stool guaic tests.He had ecchymotic patches<br />

between his skin eruptions. Despite receiving multiple units <strong>of</strong> blood transfusion, his hematocrit failed<br />

to improve. A punch biopsy <strong>of</strong> skin lesion with immun<strong>of</strong>luorescence studies revealed bullous<br />

pemphigoid. Coagulation studies revealed an elevated PTT <strong>of</strong> 49.6 with normal values <strong>of</strong> PT (10.6),<br />

An uncommon Hematological manifestation <strong>of</strong> Ulcerative Colitis<br />

Narender Annapureddy, MD Vijay Kanakadandi, MD Rishi Malhan, MD Girish Nadkarni, MD MPH CPH<br />

Natraj Ammakkanavar, MD Shiv Kumar Agarwal, MD Manpreet Sabharwal, MD<br />

INTRODUCTION: Ulcerative Colitis (UC) is associated with a number <strong>of</strong> extraintestinal manifestations in<br />

up to 40% <strong>of</strong> the cases and can occasionally causes hematological abnormalities. Anemia, autoimmune<br />

hemolytic anemia and rarely Thrombotic Thrombocytopenic Purpura (TTP) can occur. Here we report <strong>of</strong><br />

a case <strong>of</strong> TTP associated with UC.<br />

CASE PRESENTATION: 43 year old female with history <strong>of</strong> UC was initially admitted for an exacerbation<br />

<strong>of</strong> UC, treated appropriately and was discharged on mesalamine and prednisone after 2 days <strong>of</strong><br />

hospitalization. Patient returned to the hospital 2 days after Discharge with worsening symptoms and<br />

reported that she was noncompliant with her therapy. On the second day <strong>of</strong> hospitalization her platelets<br />

dropped to 44,000/mm3 from 231,000/mm3 on admission and her hematocrit dropped to 21.6% from<br />

30.5%. she also developed acute kidney injury with a rise in her creatinine from baseline <strong>of</strong> 0.9 mg/dL to<br />

2.8. Lactate dehydrogenase (8011 u/L), total bilirubin (11.9 mg/dL) and direct bilirubin (1.2 mg/dL) were<br />

elevated. haptoglobulin was decreased at 8 mg/dL, aspartate transaminase(187 U/L) was elevated with<br />

normal alanine transaminase. Complements levels were normal. D-dimer and fibrinogen levels were also<br />

normal. Heparin induced platelets antibodies and Serotonin release assay were both negative.<br />

Peripheral smear showed schistocytes and helmet cells a presumed diagnosis <strong>of</strong> TTP was made and<br />

patient started on plasmapheresis. Danazol was also started at 600mg per institution policy. Workup for<br />

vasculitis and other autoimmune disorders was negative. ADAMTS-13 activity was 150,000/mm3 and<br />

plasmapheresis was subsequently tapered after a total <strong>of</strong> 15 days. At the time <strong>of</strong> discharge her renal<br />

function had returned to baseline and her platelets were 314,000/mm3.<br />

DISCUSSION: Extraintestinal manifestations <strong>of</strong> UC are reported in up to 40% <strong>of</strong> patients. Hematological<br />

complications are relatively uncommon except for anemia both from iron deficiency and from chronic<br />

disease. There have been few reported cases <strong>of</strong> TTP associated with UC and it has been reported to be<br />

relatively resistant to medical management. Both the diseases represent autoimmune disorders and<br />

generally respond well to immunosuppressive therapy. TTP is characterized by fever, microangiopathic<br />

hemolytic anemia, thrombocytopenia, neurological symptoms and renal failure. Idiopathic or acquired<br />

TTP is characterized by inhibition <strong>of</strong> ADAMTS13, a metalloproteinase responsible for the breakdown<br />

<strong>of</strong> von Willebrand factor (vWF), which links platelets, blood clots, and the blood vessel wall in the process<br />

<strong>of</strong> blood coagulation. In any patient with UC with a sudden drop in platelets TTP should be always<br />

considered as early diagnosis and initiation <strong>of</strong> plasmapheresis can prevent significant mortality and<br />

morbidity.<br />

Thrombocytopenia in a patient with autoimmune disease<br />

Narender Annapureddy, MD Shiv Kumar Agarwal, MD Manpreet Sabharwal, MD Vijay Kanakadandi, MD<br />

Girish Nadkarni, MD MPH CPH Natraj Ammakkanavar, MD<br />

INTRODUCTION: Thrombotic thrombocytopenic purpura (TTP) is an uncommon cause <strong>of</strong><br />

thrombocytopenia characterized by decreased levels <strong>of</strong> ADAMTS13. In most <strong>of</strong> the cases the etiology is<br />

unknown. It has been associated with certain medications, infections like HIV, autoimmune diseases<br />

especially with systemic lupus erthyematosus. Here we report a case <strong>of</strong> TTP in a patient with<br />

rheumatoid arthritis (RA) on methotrexate.<br />

CASE PRESENTATION: A 22-year-old female with past medical history <strong>of</strong> RA was brought to the<br />

emergency room for alteration in mental status. Her home medications included methotrexate which<br />

was started 6 months ago when she was diagnosed with RA. Vital signs on presentation were<br />

temperature 101 degrees Fahrenheit, blood pressure 120/78 mm Hg, pulse rate 110/min, respiratory<br />

rate 20/min, oxygen saturation 95% on room air. On physical examination, the patient was lethargic but<br />

had a nonfocal neurological examination. On blood chemistries total bilirubin was 4.8 mg/dL with direct<br />

bilirubin <strong>of</strong> 1.4 mg/dL, creatinine was 0.9 mg/dL. Aspartate transaminase was elevated at 95 U/L with<br />

normal alanine transaminase. Lactate dehydrogenase was 5768 U/L and haptoglobin was 8 mg/dL. On<br />

blood counts her hematocrit was 18.9% decreased from 35% 6 months ago and her platelets were 13<br />

k/uL decreased from 262 K/uL 6 months prior. Reticulocyte count was 11.7%. D-dimer was evelated at<br />

2.9 ug/mL with normal fibrinogen levels. Peripheral smear showed 2+ schistocytes. A lumbar puncture<br />

was performed given the patient’s mental status, which was negative for cells and for syphilis screen. A<br />

computed tomography angiogram <strong>of</strong> the chest was performed which was negative for pulmonary<br />

embolism. A presumptive diagnosis <strong>of</strong> TTP was made and patient was initiated on plasmapheresis along<br />

with prednisone 1mg/kg/day. Antinuclear antibodies were negative, Rheumatoid factor was negative,<br />

Cyclic citrullinated peptide IgG was positive at 128 Units (0-19 Units normal). C3 and C4 levels were<br />

decreased at 67 mg/dL and 7.88 mg/dL. Sjogren antibodies, SSA was positive at 78.50 EU/ML and SSB<br />

was negative. ADAMTS13 levels were decreased at 10% activity. Patient responded after plasmapharesis<br />

for 10 days but recurred within 4 days <strong>of</strong> tapering plasmapheresis. The patient was then treated with<br />

rituximab intravenously for 4 weeks along with plasmapheresis with good response. Patient had<br />

improvement in mental status and improvement in platelets to 420 K/uL was subsequently discharged<br />

with follow up.<br />

DISCUSSION: Microangiopathic hemolytic anemia (MAHA) presents a diagnostic challenge in patients<br />

with autoimmune disorders as it may be part <strong>of</strong> the spectrum. Measuring ADAMTS13 levels and other<br />

markers <strong>of</strong> autoimmune disorders is important as it helps to distinguish between idiopathic TTP<br />

associated with autoimmune disorder versus MAHA from autoimmune disease as it helps guide<br />

therapeutic choices. MAHA from autoimmune disorders might be refractory to plasmapheresis and need<br />

stronger immunosuppresion compared to idiopathic TTP.<br />

INTRODUCTION: Complementary medicine utilization continues to enjoy an impressive amount <strong>of</strong><br />

attention and consumption but their potential for current or future toxicity seems considerable and<br />

concerning. Vitamin D intoxication that is associated with the consumption <strong>of</strong> dietary supplements is<br />

reported rarely.<br />

CASE PRESENTATION: We present an interesting case <strong>of</strong> 59 year old caucasian lady with history <strong>of</strong><br />

multiple sclerosis, osteoporosis, breast cancer status post lumpectomy , radiation and chemotherapy.<br />

She presented with c/o weakness, fatigue, headache , constipation, short term memory loss and<br />

started on aggressive intravenous hydration and intensive monitoring leading to rapid resolution <strong>of</strong><br />

symptoms. A complete diagnostic work up for hypercalcemia was performed. PTH levels were<br />

suppressed at 5.6 pg/ ml arousing suspicion for hypercalcemia due to malignancy (prior history <strong>of</strong> breast<br />

cancer/ new primary). However her PTHrP levels were within normal limits (0.8 pmol/ l). TSH (0.623<br />

IU/L) and free T4 (2.87 ng/dl) were also within normal limits. 25- hydroxy Vitamin D level was high at<br />

96ng/ ml, while 1-25 hydroxy vitamin D was 28 pg/ ml (10-65 pg/ ml). Review <strong>of</strong> her medication list<br />

showed daily intake <strong>of</strong> 800 units <strong>of</strong> vitamin D and 500 mg <strong>of</strong> calcium. With limited sun exposure in<br />

Central New York, how our patient managed to achieve such a degree <strong>of</strong> symptomatic hypervitaminosis<br />

D became a mystery waiting to be resolved. We investigated her for granulomatous diseases and other<br />

causes <strong>of</strong> hypervitaminosis D.The patient denied overdosing on prescription vitamin D initially but later<br />

admitted that she was ingesting an expensive naturally derived gel preparation containing about 16,000<br />

IU <strong>of</strong> vitamin D daily for last 10 months. This was one <strong>of</strong> several alternative medications she was<br />

prescribed online by practitioner <strong>of</strong> alternative medicine to cure her multiple sclerosis and osteoporosis.<br />

We counseled and provided information to the patient on potential side effects <strong>of</strong> excessive vitamin D<br />

supplementation and other alternative preparations and withheld the same at the time <strong>of</strong> discharge.<br />

DISCUSSION: Annually, 34 billion dollars are spent on complementary and alternative medicine (CAM)<br />

in the U.S.A. . Surveys suggest that the potential for a negative drug - supplement interaction<br />

in users can be as high as 40%.The majority <strong>of</strong> the expense on CAM is directed towards “self-care,” and<br />

is done without physician approval or guidance. CAM is not regulated by the FDA , thus<br />

manufacturers tend to make unfounded health benefit claims while concealing the potential side effects<br />

as was the case with our patient.<br />

Adrenal Carcinoma Presenting as Hypoglycemia: A Case Report<br />

Ruthie May U Chua, MD Joanna Manzano MD, Moshe Schiffmiller MD, Jennifer Poste, Stephen<br />

Jesmajian<br />

INTRODUCTION: Cushing’s syndrome can be secondary to a rare primary adrenocortical malignancy.<br />

Patients with functional adrenocortical tumor present a unique challenge because <strong>of</strong> complexities in<br />

diagnosing and managing multiple metabolic derangements.<br />

CASE PRESENTATION: We present the case <strong>of</strong> a 55 year-old overweight African <strong>American</strong> gentleman<br />

with history <strong>of</strong> insulin-dependent diabetes mellitus, hypertension, vitamin D deficiency and<br />

schizophrenia who was admitted for seizure secondary to a hypoglycemic episode. The patient had<br />

multiple Emergency Room visits for both hypoglycemia and hyperglycemia over the past two months.<br />

During the current hospitalization his blood glucose on admission was 23 mg/dl. His insulin was held and<br />

he was started on intravenous dextrose. Laboratory exam revealed metabolic alkalosis with a<br />

bicarbonate <strong>of</strong> 36.5 mmol/L and hypokalemia with potassium <strong>of</strong> 2.5 mmol/L. He remained hypokalemic<br />

despite repletion. Multiple hypoglycemic episodes ensued despite holding insulin.<br />

On review <strong>of</strong> previous radiographic records done two months prior to admission, patient was found to<br />

have an 8x9x11 cm heterogeneous lobulated s<strong>of</strong>t-tissue mass contiguous with the left kidney, pancreas<br />

and stomach. A second CT performed approximately one month later showed new pulmonary and<br />

hepatic masses suspicious for metastases. Review <strong>of</strong> previous laboratory records revealed low<br />

aldosterone:renin ratio (1ng/dl:3.94ng/ml), C peptide (0.22ng/ml) and insulin (less than 2 micro IU). We<br />

performed a 1 mg dexamethasone suppression test which confirmed hypercortisolism with serum<br />

cortisol level <strong>of</strong> 31.2 mcg/dL. A Serum ACTH while the patient was hypoglycemic was within normal<br />

limits (34pg/ml). The diagnosis <strong>of</strong> advanced adrenocortical carcinoma (ACC) with Cushing’s syndrome<br />

was suspected and chemotherapy with mitotane was planned. The patient however had persistent<br />

hypoglycemic episodes and subsequently went into cardiopulmonary arrest.<br />

DISCUSSION: Adrenocortical carcinoma is highly aggressive and rare, occurring in approximately 1 per<br />

million population per year. Sixty percent <strong>of</strong> these tumors are secretory, <strong>of</strong> which 45% cause Cushing’s<br />

syndrome. Clinical symptoms develop very rapidly in a course <strong>of</strong> few months. This patient presented<br />

with symptoms <strong>of</strong> Cushing’s syndrome confounded with repeated hypoglycemic episodes. This<br />

increased glucose utilization is thought to be most likely induced by paracrine release <strong>of</strong> insulin-like<br />

growth factor 2. CT scan findings are typical <strong>of</strong> adrenal cancer and biopsy is not necessary to establish a<br />

diagnosis <strong>of</strong> a primary malignancy. Primary curative treatment for ACC is surgery. Our patient who<br />

already presented with advanced disease was not a candidate for surgery and would have benefited<br />

from mitotane therapy. However, five year survival rate <strong>of</strong> advanced disease is still only 10%. This case<br />

illustrates that repeated hypoglycemia in a diabetic patient warrants more than cursory quick fixes and<br />

should prompt physicians to investigate further.<br />

THORACIC ENDOMETRIOSIS IN A YOUNG WOMAN PRESENTING WITH ABDOMINAL PAIN<br />

Karen de Castro Dah, MD Second Author: Nelson Chan-Hung, MD<br />

INTRODUCTION: Endometriosis is a disease characterized by the presence <strong>of</strong> endometrium-like<br />

tissue outside <strong>of</strong> the uterine cavity. The disease affects 5-15% <strong>of</strong> women in the reproductive age, where<br />

up to 12% are extrapelvic in location. An estimated 2% <strong>of</strong> extrapelvic endometriosis involves the<br />

thorax.<br />

CASE PRESENTATION: A twenty seven year old Haitian female presented to the emergency<br />

department with abdominal pain associated with the onset <strong>of</strong> her menstruation. She denied any chest<br />

pain or shortness <strong>of</strong> breath. Routine chest x-ray showed a large right pleural effusion and 2000<br />

milliliters <strong>of</strong> bloody pleural fluid was drained in the emergency department. Abdominal computed<br />

tomography scan showed bilateral cystic appearing adnexa and a large right pleural<br />

effusion. Transvaginal ultrasound showed a normal sized uterus with thickened endometrium and<br />

bilaterally thickly enlarged ovaries with small cystic structures. She underwent a diagnostic laparoscopy<br />

and both peritoneal and vaginal biopsies were taken. Clinical diagnosis indicated Stage IV endometriosis<br />

however the biopsies revealed no evidence for endometriosis. Thoracic surgery performed video<br />

assisted thoracic surgery with right upper and middle lobe wedge resection and additional biopsies <strong>of</strong><br />

the right diaphragm and parietal pleura were taken. The samples were consistent with<br />

endometriosis. The patient had no major complications from the procedure and received hormonal<br />

treatment with leuprolide and medroxyprogesterone before discharged.<br />

DISCUSSION: This case represents a rare disease entity that has yet to be fully discovered. Thoracic<br />

endometriosis, the growth <strong>of</strong> endometrial tissues in the lungs or on the pleura, comprises four clinical<br />

findings including catamenial pneumothorax, hemothorax, and hemoptysis, and endometriotic lung<br />

nodules. Catamenial hemothorax occurs in approximately 14% <strong>of</strong> thoracic endometriosis and involves<br />

the right side in almost all reported cases. Presently, there is a lack <strong>of</strong> a single proposed hypothesis<br />

explaining the mechanism <strong>of</strong> intrathoracic endometrial implantation, and general information pertaining<br />

to thoracic endometriosis remains in short supply. Current treatment <strong>of</strong> thoracic endometriosis consists<br />

<strong>of</strong> both hormonal treatment, with oral contraceptives or gonadotropin-releasing hormone agonist, and<br />

surgical removal <strong>of</strong> involved areas through video assisted thoracic surgery or open thoracotomy which<br />

provides targeted treatment to the affected areas. With no treatment modality having yet been shown<br />

to be both superior and effective, data regarding short and long term treatment outcomes remains both<br />

variable and scarce.<br />

Ayurvedic Remedy For Diabetes As A cause Of Lead Poisoning<br />

Amishi Desai, MBBS Harry Staszewski MD<br />

INTRODUCTION: The popularity <strong>of</strong> alternative or complementary medicine has dramatically increased<br />

over the years. They are assumed by patients to be safe and free <strong>of</strong> side effects. Ayurveda, a traditional<br />

medical system in India, has been in practice for more than 5000 years. Published case reports have<br />

demonstrated that ayurvedic formulations may contain large quantities <strong>of</strong> heavy metals and it is<br />

possible that these minerals are added intentionally after the formulations have undergone a<br />

“detoxification” process.<br />

CASE PRESENTATION: We present a 56 year old male, who came to the emergency room with diffuse<br />

abdominal pain, decreased oral intake and constipation. Laboratory values showed that hemoglobin had<br />

dropped to 9.7 grams per deciliter (from a baseline <strong>of</strong> 14 grams per deciliter). Levels <strong>of</strong> serum iron,<br />

transferrin, haptoglobin, vitamin B12 and folic acid were within normal limits. Patient had a normocytic<br />

anemia with elevated reticulocyte count and liver enzymes were mildly elevated. Abdominal computed<br />

tomography was normal. He underwent an upper endoscopy and a colonoscopy which were negative.<br />

Peripheral smear showed prominent basophilic stippling promoting measurement <strong>of</strong> blood lead levels<br />

that was markedly elevated (101 microgram per deciliter). Emergent chelation therapy with dimercaprol<br />

(BAL) and calcium EDTA was started and patient was later discharged on oral succimer for two weeks.<br />

On further enquiry patient reported travel to India three months back where he was prescribed<br />

ayurvedic medicine for diabetes which he had been taking continuously since 2-3 months. The ayurvedic<br />

powder was sent for chemical analysis. The lead content was 62 percent.<br />

DISCUSSION: According to Ayurveda, toxic heavy metals such as lead and mercury play an important<br />

role in healthy functioning <strong>of</strong> the human body. Ayurvedic medications have been used in the past for<br />

pain, arthritis, psoriasis, impotence, infertility and as aphrodisiacs. Lead toxicity from ayurvedic<br />

medicine, used for diabetes has rarely been reported. To our knowledge there have been only three<br />

documented case reports where lead toxicity has occurred from an ethnic remedy taken for diabetes<br />

and its long term complications. People opt for alternative medicine because they believe it has lesser<br />

side effects than a more natural form <strong>of</strong> therapy. In ayurvedic medicine lead is regarded as an<br />

aphrodisiac and its role may have been to counter the impotence associated with diabetes. The present<br />

case brings to light the need to take a thorough medical history, including previous and current drug<br />

therapy. However, some patients do not consider herbal medications drugs, whereas, others are<br />

uncomfortable about providing information on the use <strong>of</strong> these preparations. Thus physicians must<br />

specifically ask patients about their use <strong>of</strong> unconventional medicines.<br />

A RARE FINDING IN A RARE OVARIAN MALIGNANCY<br />

Christopher Dittus, DO (Associate Member) Second Author: Christos Fountzilas, MD (Associate<br />

Member) Third Author: Robert Graham, MD (Fellow) Fourth Author: Amanda Magee, DO (Member)<br />

INTRODUCTION:Ovarian malignancies have the highest mortality <strong>of</strong> all female gynecologic tumors in<br />

the United States. According to the WHO Classification <strong>of</strong> ovarian neoplasms, 65% <strong>of</strong> these tumors are<br />

epithelial in origin, 25% are <strong>of</strong> germ cell origin, and 6% are <strong>of</strong> sex-cord stromal origin. Less than 1% <strong>of</strong> all<br />

ovarian malignancies are carcinosarcomas. A unique and rare entity is carcinosarcoma with<br />

neuroendocrine differentiation. These tumors have been documented in other organs, but to our<br />

knowledge there are no reported cases <strong>of</strong> primary ovarian origin. Herein, we present a case <strong>of</strong><br />

carcinosarcoma <strong>of</strong> the ovary with neuroendocrine differentiation.<br />

CASE PRESENTATION: A 60-year-old female presented with right lower extremity edema extending to<br />

the upper thigh. The patient’s medical history included chronic hepatitis C and a remote history <strong>of</strong><br />

breast cancer. Physical examination revealed distended abdomen with a large, palpable mass and right<br />

lower extremity pitting edema and tenderness. Computerized tomography <strong>of</strong> chest, abdomen and pelvis<br />

revealed extensive bilateral pulmonary emboli, including saddle embolism, right common femoral deep<br />

venous thrombosis, and a large heterogeneously enhancing mass projecting from the pelvis into the mid<br />

abdomen. The patient was subsequently referred to surgery for elective total abdominal hysterectomy<br />

with bilateral salpingo-oophorectomy and omentectomy. Histology revealed carcinosarcoma consisting<br />

<strong>of</strong> a high-grade neuroendocrine epithelial component and a rhabdomyosarcomatous mesenchymal<br />

component. The tumor was most consistent with an ovarian primary. The patient declined further<br />

treatment and was discharged to hospice.<br />

DISCUSSION: While carcinosarcomas <strong>of</strong> the ovary have been well documented, carcinosarcomas <strong>of</strong> the<br />

ovary with neuroendocrine differentiation have not been well described. Carcinosarcomas contain both<br />

malignant epithelial and sarcomatous elements. The epithelial component is most <strong>of</strong>ten<br />

adenocarcinoma, but may also be squamous cell carcinoma. Very rarely the epithelial component<br />

consists <strong>of</strong> neuroendocrine tissue, which has been described more commonly in gastric, esophageal,<br />

uterine, and adnexal lesions. The sarcomatous element may be homologous tissue native to the ovary,<br />

or heterologous tissue not native to the ovary. Patients present with symptoms similar to those with<br />

epithelial ovarian cancer, but have comparatively worse outcomes. After cytoreductive surgery, the<br />

consensus recommendation for carcinosarcoma <strong>of</strong> the ovary is a platinum-based chemotherapy<br />

combination. This chemotherapy regimen generally has a poor response rate due to the inherent<br />

heterogeneity <strong>of</strong> the tumor. Our patient’s case was complicated due to the tumor’s neuroendocrine<br />

differentiation. Consequently, carcinosarcomas with neuroendocrine differentiation must be researched<br />

further, as they are extremely rare tumors that are associated with poor outcomes.<br />

A Rare Case <strong>of</strong> Campylobacter jejuni Associated Myocarditis<br />

Shira B Eytan, MD Robert E Graham MD, MPH<br />

INTRODUCTION:Campylobacter jejuni is a common cause <strong>of</strong> food poisoning, enteritis and diarrhea<br />

worldwide. Although rare, we present a potentially life threatening complication: Campylobacter jejuni<br />

associated myocarditis in an immunocompetent patient.<br />

CASE PRESENTATION: A 34 year old previously healthy white man presents with a three-day history <strong>of</strong><br />

watery diarrhea, fever, cough productive <strong>of</strong> clear phlegm, abdominal and chest discomfort,<br />

chills, general malaise, no fevers. He also reported multiple episodes <strong>of</strong> watery diarrhea. Patient is from<br />

Australia and vacationing on his honeymoon in the US; he had just arrived in New York from the west<br />

coast when he presented to our emergency department. Past medical history includes depression for<br />

which he takes Paroxetine, but he denies any pulmonary, cardiac, or gastrointestinal history.<br />

Lev<strong>of</strong>loxacin was initiated for presumed pneumonia in light <strong>of</strong> cough and possible effusion/consolidation<br />

on chest x-ray. Leukocytosis <strong>of</strong> 22 x103/uL was found and blood cultures were negative. Cardiac pr<strong>of</strong>ile<br />

returned slightly positive with Troponin I 0.145ng/ml, CK 134 U/L. EKG at this time showed normal sinus<br />

rhythm with LBBB, with no old EKG for comparison. Echocardiogram was performed which showed<br />

severely hypokinetic walls, and an estimated left ventricular ejection fraction <strong>of</strong> 20-25%. At this point,<br />

patient was diagnosed with myocarditis and transferred to CCU for closer monitoring. Subsequent CT<br />

angiogram for cardiac structure showed normal coronary arteries. Infectious and rheumatologic workup<br />

for the cause <strong>of</strong> myocarditis returned only a positive Campylobacter jejuni stool culture. Patient was<br />

continued on Lev<strong>of</strong>loxacin, and diarrhea resolved. He was discharged six days after admission with an EF<br />

<strong>of</strong> 54%.<br />

DISCUSSION: Myocarditis is a rare but potentially serious complication <strong>of</strong> infectious disease, with<br />

potential sequelae <strong>of</strong> life-threatening arrhythmia and congestive heart failure. There have only been a<br />

few reported cases <strong>of</strong> Campylobacter jejuni associated myocarditis. Interestingly, the majority <strong>of</strong> cases<br />

have occurred in young immunocompetent males, and resulted in completed resolution. Although the<br />

pathophysiology is unclear, it is thought to be caused by an autoimmune inflammatory reaction. This<br />

case highlights the need for consideration <strong>of</strong> Campylobacter jejuni infection as a cause <strong>of</strong> new<br />

myocarditis in an immunocompetent patient with enteritis.<br />

Dabigatran overdose secondary to acute kidney injury<br />

Christos Fountzilas, MD, Christopher Dittus DO, Jerry George DO, Randy Levine MD.<br />

INTRODUCTION:Direct thrombin inhibitors and factor Xa inhibitors have improved treatment <strong>of</strong> non<br />

valvular atrial fibrillation, with more predictable pharmacokinetics and pharmacodynamics when<br />

compared to warfarin. However, safety concerns have been raised since there is no antidote to these<br />

new agents for treatment <strong>of</strong> secondary hemorrhages.<br />

CASE PRESENTATION: We present the case <strong>of</strong> an 82 year old female with a history <strong>of</strong> non valvular<br />

atrial fibrillation who was switched from warfarin to dabigatran one week prior to presentation, and<br />

who presented with evidence <strong>of</strong> dabigatran overdose.<br />

The patient presented to the emergency department with complaints <strong>of</strong> generalized weakness, dizziness<br />

and decreased appetite for the past 2 days along with nausea and an episode <strong>of</strong> vomiting the day <strong>of</strong><br />

presentation. The patient denied melena, hematochezia, hematemesis, hemoptysis, epistaxis, or any<br />

other signs <strong>of</strong> bleeding. Apart from atrial fibrillation, the patient had a history <strong>of</strong> chronic systolic<br />

congestive heart failure with implantation <strong>of</strong> an AICD, coronary artery disease, hypertension and<br />

hyperlipidemia. She had been treated with dabigatran 150 mg twice daily, carvedilol, simvastatin,<br />

furosemide and amiodarone.<br />

Vital signs on admission were stable and physical examination unremarkable. A complete blood count<br />

was significant only for mild thrombocytopenia (platelets 95,000/mcl) which had been stable for several<br />

years. The peripheral blood smear showed occasional schistocytes. Chemistry revealed only elevated<br />

creatinine <strong>of</strong> 1.78 mg/dl from a baseline <strong>of</strong> 1 mg/dl one week before. INR was 7.25 and PTT 135 seconds.<br />

The patient denied any warfarin, and that was confirmed with the patient’s home health assistant and<br />

family.<br />

Fibrinogen level was below 80mg/dl, D-Dimer level less than 150 ng/dL and thrombin time was more<br />

than 120 seconds, consistent with excessive anticoagulation secondary to dabigatran. Dabigatran was<br />

held with resolution <strong>of</strong> coagulopathy over the next 4 days. Subsequently, dabigatran was started at a<br />

lower dose <strong>of</strong> 75mg twice daily.<br />

DISCUSSION: We present the case <strong>of</strong> dabigatran overdose in a patient who was treated with a<br />

seemingly appropriate dose. Our patient developed mild renal insufficiency after a brief gastrointestinal<br />

illness (possibly due to dehydration) which led to decreased clearance <strong>of</strong> the drug. This was<br />

compounded by the concomitant intake <strong>of</strong> amiodarone, a p-glycoprotein inhibitor that can increase<br />

peak plasma concentrations <strong>of</strong> dabigatran. The combination <strong>of</strong> these two events led to her overdose<br />

and presents a cautionary tale.<br />

The Story Of A Tricky Tick<br />

INTRODUCTION: Diabetic ketoacidosis (DKA) is a potentially lethal condition <strong>of</strong>ten presenting in<br />

patients who have an underlying disease process or are poor compliance with their insulin regimen.<br />

Ehrlichiosis while endemic in the Southeastern, South Central, and Mid-Atlantic regions <strong>of</strong> the United<br />

States is rare in Central New York especially in the winter months.<br />

CASE PRESENTATION: We present the case <strong>of</strong> an 80 year old veteran who presented with 3 week<br />

history <strong>of</strong> worsening malaise, fevers, night sweats, along with nausea and abdominal pain that was also<br />

associated with poor oral intake. The patient was subsequently found to be in DKA with an elevated<br />

anion gap and was transferred to the ICU. At the time <strong>of</strong> admission, he was also found to have<br />

thrombocytopenia, mild anemia, leukopenia and elevated liver enzymes. Since he was noted to be<br />

febrile, blood cultures and urine culture were also ordered to identify a possible infectious<br />

etiology. While a staff member was helping the patient in the ICU, she noticed an engorged tick on the<br />

patient’s left shoulder. The tick was procured for arthropod identification and was found to be Ixodes<br />

sp. Patient was treated with Doxycycline as well as Azithromycin and Atovaquone to treat for possible<br />

co-infection with other tick borne illnesses. On further inquiring, patient admitted to visiting his<br />

daughter in Mount Kisco in Westchester County, NY for Thanksgiving and going for a long walk in the<br />

woods three weeks prior to his admission. Subsequently, thin and thick smears, and serologies were<br />

sent for identification <strong>of</strong> possible tick borne illnesses including Lyme’s disease, Babesiosis, Rocky<br />

Mountain Spotted Fever, Anaplasmosis, and Ehrlichiosis. Patient’s blood smear demonstrated<br />

intracytoplasmic inclusions (morulae) suggestive <strong>of</strong> Granulocytic Ehrlichiosis.<br />

DISCUSSION: Human ehrlichiosis is a serious disease with significant morbidity, particularly if<br />

appropriate antibiotics are delayed. Through this case we hope to highlight that one should have a high<br />

degree <strong>of</strong> suspicion for tick borne infections in endemic areas regardless <strong>of</strong> the season. The timely<br />

discovery <strong>of</strong> a tick on our patient was potentially life-saving. A physical exam in a febrile patient should<br />

include a thorough skin exam for tick bites. We also would like to emphasize that until a confirmed<br />

diagnosis is obtained, patients should be empirically treated for all tick-borne diseases as the <strong>of</strong>ten<br />

typical clinical findings <strong>of</strong> rashes <strong>of</strong> Rocky Mountain Spotted Fever or Lyme’s disease may mislead the<br />

clinician into ignoring possible co-infection with ehrlichiae or babesia.<br />

When the Bleeding Won’t Stop: A Case Cluster <strong>of</strong> Ruptured Hepatoma<br />

Robert J Gianotti III, Keri Herzog, Karin Warltier<br />

INTRODUCTION: Hepatocellular carcinoma is one <strong>of</strong> the most common tumors worldwide, with up to<br />

85% <strong>of</strong> cases occurring with cirrhosis. Tumor rupture is a rare, but morbid complication occurring in 3-<br />

15% <strong>of</strong> cases, with a higher incidence in Asia. A high index <strong>of</strong> suspicion for rupture is needed for prompt<br />

recognition in patients with the acute onset <strong>of</strong> abdominal pain in the setting <strong>of</strong> hepatocellular<br />

carcinoma.<br />

CASE PRESENTATION: Case 1: A 22 year old man from Guinea with no medical history presented to<br />

our hospital complaining <strong>of</strong> abdominal distention and anorexia. On physical exam he was noted to have<br />

a large, firm abdominal mass. Computed tomography <strong>of</strong> the abdomen revealed a giant hepatoma <strong>of</strong> the<br />

right and middle lobes <strong>of</strong> the liver with compression <strong>of</strong> the supra-renal inferior vena cava. He was<br />

diagnosed with chronic Hepatitis B infection. Prior to beginning treatment with Sorafenib, he had an<br />

acute onset <strong>of</strong> abdominal pain and tachycardia. Repeat imaging revealed rapid tumor progression and<br />

hemorrhage anterior to the falciform ligament with active contrast extravasation. The patient was<br />

admitted to our palliative care unit and subsequently passed away.<br />

Case 2: A 65 year old man with hepatitis C initially presented to an outside hospital complaining <strong>of</strong><br />

nausea and vomiting. On exam he had ascites and paracentesis showed frank blood. Computed<br />

tomography showed cirrhosis, multiple liver masses and a large hematoma posterior to the right lobe <strong>of</strong><br />

the liver. He required multiple blood transfusions and was transferred to our hospital for possible transarterial<br />

embolization. On transfer the patient was tachypneic with severe abdominal pain. The patient's<br />

prognosis and options were discussed. He wished to focus on achieving comfort. The patient was<br />

transferred to our palliative care unit.<br />

Case 3: A 74 year old man with a history <strong>of</strong> alcoholism and hepatitis C presented to our hospital with<br />

abdominal pain. He had a tender and distended abdomen. Computed tomography showed a 15 cm<br />

heterogeneous tumor abutting the right hepatic vein and IVC within a nodular liver. Alpha-fetoprotein<br />

was 179 ng/mL. He was not considered a surgical candidate due to the large size <strong>of</strong> the tumor. On<br />

hospital day 7, he reported severe abdominal pain and had worsening anemia. Diagnostic paracentesis<br />

revealed frank blood, confirming hemoperitoneum. He was planned for trans-arterial embolization, yet<br />

passed away before any intervention.<br />

DISCUSSION: Here we report a universally fatal outcome in patients presenting with rupture in the late<br />

stages <strong>of</strong> hepatocellular carcinoma. Diagnostic paracentesis and computed tomography can confirm<br />

both the presence <strong>of</strong> and source <strong>of</strong> blood. Early referral to hospice was the treatment <strong>of</strong> choice in our<br />

cohort, and should be considered only in patients with very advanced disease and poor prognosis.<br />

Patients with good functional status, adequate liver function or smaller tumor size who present with<br />

tumor rupture should be urgently referred for trans-arterial embolization and in some cases,<br />

hepatectomy.<br />

Hematology-Oncology Department <strong>of</strong> Medicine Stony Brook School <strong>of</strong> Medicine Stony Brook, NY 11794<br />

INTRODUCTION: Hepatocellular carcinoma has been known in rare instances to metastasize to the<br />

right atrium. We report a case <strong>of</strong> a newly diagnosed Grade 2-3 Hepatocellular carcinoma that initially<br />

presented with vague complaints <strong>of</strong> abdominal pain, constipation and shortness <strong>of</strong> breath. The unusual<br />

clinical presentation was consistent with tumor thrombosis <strong>of</strong> the inferior vena cava (IVC) extending to<br />

the right atrium and encroaching the tricuspid valve. This case demonstrates a life-threatening<br />

manifestation <strong>of</strong> metastatic hepatocellular carcinoma and highlights the importance <strong>of</strong> early diagnosis in<br />

these patients.<br />

CASE PRESENTATION: A 61 year old morbidly obese female presented to the emergency department<br />

with 4 day complaints <strong>of</strong> diffuse abdominal pain described as dull, constipation and mild shortness <strong>of</strong><br />

breath on exertion. Past medical history was significant for COPD, hepatitis C (treated) and SLE. On initial<br />

presentation her vitals were as follows: BP 141/88, P 104, R 18, T 36.7. Physical exam was remarkable<br />

only for tachycardia and mild RUQ tenderness. Abdominal CT scan revealed the presence <strong>of</strong> a large<br />

filling defect in the inferior vena cava with extension into the right atrium, as well as a liver lesion. Twodimensional<br />

echocardiogram demonstrated a large mobile echodensity in the right atrium, measuring<br />

approximately 5.33 x 2.81 cm and intermittently descending into the plane <strong>of</strong> the tricuspid valve. The<br />

diagnosis <strong>of</strong> HCC was presumed based on an alpha-fetoprotein titer <strong>of</strong> 144,912 and CT imaging that<br />

supported this diagnosis. This was later confirmed on liver biopsy. The patient was evaluated by<br />

cardiothoracic surgery, however due to her poor functional status she was deemed unfit for surgery.<br />

Medical oncology was consulted, and the patient was informed that she may be a candidate for<br />

Nexavar. The patient was stabilized and ultimately discharged home, but was readmitted soon<br />

thereafter in fulminant hepatic failure and passed away in the hospital less than 3 weeks after her initial<br />

diagnosis.<br />

DISCUSSION: Cardiac involvement in HCC is rarely encountered. It usually indicates a more advanced<br />

form <strong>of</strong> disease with poor prognosis. Presenting symptoms <strong>of</strong>ten mimic those <strong>of</strong> heart failure but may<br />

be nonspecific as in the case <strong>of</strong> our patient. There are reports <strong>of</strong> patients with good functional status<br />

who underwent surgical removal <strong>of</strong> right atrial mass with good outcomes. Our patient was unfit for<br />

surgery and based on her Childs-Pugh score, she was not eligible for Nexavar (Sorafenib). Patients in this<br />

situation are <strong>of</strong>ten left with only the option <strong>of</strong> palliative therapy. The detection <strong>of</strong> extrahepatic<br />

metastatic disease, therefore, becomes crucial in the early diagnosis and treatment <strong>of</strong> HCC.<br />

Cytomegalovirus Induced Collapsing Focal Segmental Glomerulosclerosis<br />

Vanya Grover, DO Additional Authors: Meghana Gaiki, MD, Maria Devita, MD and Joshua Schwimmer,<br />

MD<br />

INTRODUCTION: Collapsing glomerulopathy is a rare cause <strong>of</strong> rapidly progressive renal failure. It is<br />

considered a variant <strong>of</strong> focal segmental glomerulosclerosis, occurring in both immunocompetent and<br />

well as immunocompromised hosts. Etiologies include viral infections, lymphoproliferative disorderes,<br />

and autoimmune disease. We present a rare case report linking cytomegalovirus infection to collapsing<br />

glomerulopathy in an immunocompetent host.<br />

CASE PRESENTATION: A 34 year old Hispanic male with no significant past medical history presented<br />

with the complaint <strong>of</strong> generalized malaise, nausea, and vomiting ten days prior to admission. He<br />

reported a monogamous relationship with his wife for the past eight years and denied any alcohol,<br />

Remitting Seronegative Symmetric Synovitis with Pitting Edema Associated with Acute Cholecystitis: A<br />

Case Report.<br />

Jehad M Haggiagi, MD Second Author: Karen Beekman, MD Third Author: Jennifer Wang, MD Fourth<br />

Author: Aman Deep, MD<br />

INTRODUCTION:Remitting Seronegative Symmetric Synovitis with Pitting Edema (RS3PE) is an unusual<br />

inflammatory arthritis with an unknown pathophysiology characterized by an acute onset <strong>of</strong><br />

symmetrical synovitis with pitting edema <strong>of</strong> the hands and/or feet. We report a case <strong>of</strong> RS3PE and acute<br />

cholecystitis presenting at approximately the same time.<br />

CASE PRESENTATION: A 42-year-old woman presented to the emergency department with severe,<br />

non-radiating right upper quadrant pain for two days. The patient described a dull sensation initially<br />

associated with nausea, non-bloody, non-bilious vomiting. The next day, the patient suddenly developed<br />

pain and swelling <strong>of</strong> both hands. No preceding history <strong>of</strong> trauma, headache, fever, drug intake, diarrhea,<br />

or other joint involvement was reported. Her past medical history was unremarkable. Physical exam<br />

revealed right upper quadrant tenderness and positive Murphy’s sign. Examination <strong>of</strong> both hands<br />

revealed bilateral swelling, pitting edema <strong>of</strong> the dorsum and tenderness in all the joints. Labs revealed a<br />

white blood cell count <strong>of</strong> 14 per microliter, erythrocyte sedimentation rate (ESR) <strong>of</strong> 82 mm/hr, and a Creactive<br />

protein (CRP) <strong>of</strong> 43 mg/l. Right upper quadrant sonogram showed findings consistent with<br />

acute cholecystitis. MRI <strong>of</strong> both hands revealed bilateral synovitis <strong>of</strong> the wrists, metacarpophalangeal,<br />

proximal and distal interphalangeal joints and diffuse subcutaneous edema. Rheumatoid factor (RF),<br />

anti-cyclic citrullinated protein (anti-CCP), antinuclear antibodies (ANA), anti-dsDNA, anti-Ro, anti-La,<br />

Human Leukocyte Antigen B27, and Hepatitis B and C were all negative. The diagnosis <strong>of</strong> RS3PE was<br />

suggested. A laparoscopic cholecystectomy was performed. On post-operative day one, the swelling and<br />

tenderness improved dramatically. One week after discharge, the edema and tenosynovitis resolved<br />

completely.<br />

DISCUSSION: RS3PE Syndrome is a rare inflammatory disease, first described by McCarty et al. in 1985.<br />

RS3PE Syndrome is now regarded as a distinct clinical entity. It has a 4:1 male:female predominance.<br />

Mean age at presentation in one study was 71 years with a range <strong>of</strong> 48-86. The etiology is still unknown.<br />

Possible factors associated with RS3PE include malignancy, Human Leukocyte Antigen, Parvovirus B19,<br />

and medications. Many reports suggest that RS3PE is a paraneoplastic syndrome. The pathologic<br />

mechanism <strong>of</strong> RS3PE is still unclear. Vascular endothelial growth factor (VEGF) plays a major role in<br />

pathological changes. ESR and CRP may be markers used to monitor activity, but RF and ANA are always<br />

negative. RS3PE is also characterized by a prompt response to glucocorticoids. Hydrochloroquine can be<br />

used with a lower dose <strong>of</strong> steroids. However, poor prognosis has been noted among patients with RS3PE<br />

and malignancy. In conclusion, to date, there have been no reported occurrences <strong>of</strong> RS3PE syndrome<br />

associated with acute cholecystitis, and our patient was successfully treated with only a laparoscopic<br />

cholecystectomy; this observation may be helpful in understanding the pathogenic mechanism <strong>of</strong><br />

RS3PE, revealing a more inflammatory basis for the disease not necessarily rheumatologically rooted.<br />

A Case Of Cholangitis – It Was A Fluke<br />

Stephan Heo second and third authors: Rebecca Summers, M.D., Nicole Adler, M.D.<br />

INTRODUCTION: A 45 year-old Chinese man presented with worsening abdominal pain, nausea, and<br />

vomiting over a three month period. His history began when he was born and raised in Caton, China,<br />

immigrating to the United States in adulthood. He was in his usual state <strong>of</strong> good health until three<br />

months prior to admission, when he noted the onset <strong>of</strong> abdominal pain. This progressed to worsening<br />

burning, sharp epigastric pain with radiation to the right side <strong>of</strong> the lower ribs.<br />

Physical exam revealed icteric sclera and tenderness to palpation in the epigastric and right upper<br />

quandrant area. His skin was jaundiced. Laboratory results were remarkable for an aspartate<br />

aminotransferase <strong>of</strong> 496 IU per liter, alanine aminotransferase 824 IU per liter, total bilirubin 8.5 mg per<br />

deciliter, and conjugated bilirubin 2.7 mg per deciliter. His white blood cell count was 13, 200 with 2%<br />

eosinophils.<br />

An ultrasound demonstrated intrahepatic dilatation and a mildly dilated common bile duct measuring 7<br />

cm. An endoscopic retrograde cholangiopancreatography revealed a black, pigmented stone near the<br />

ampulla with innumerable liver flukes. The liver flukes were unable to be obtained during the<br />

procedure, however, stool analysis revealed the presence <strong>of</strong> ova from Clonorchis Sinensis. Praziquantal<br />

25mg/kg every six hours for a total <strong>of</strong> three doses were given. His condition improved, and repeat stool<br />

testing showed resolution <strong>of</strong> the infection.<br />

Acute illness from Clonorchis Sinensis can occur after consumption <strong>of</strong> ova. General malaise, abdominal<br />

discomfort, and diarrhea begin ten to sixteen days after consumption and can last two to four<br />

weeks. The severity <strong>of</strong> symptoms is based on the number <strong>of</strong> flukes involved. Mild infections occur when<br />

less than 100 flukes are ingested, and present with malaise, intermittent jaundice, diarrhea and<br />

abdominal pain. Moderate infections occur with ingestion <strong>of</strong> 1000 flukes and symptoms include fevers,<br />

chills, anorexia, and weight loss. Ingestion <strong>of</strong> greater than 1000 flukes causes symptoms <strong>of</strong> acute right<br />

upper quadrant pain and jaundice. Recognition and treatment with praziquental or an alternative agent<br />

such as albendazole is critical to prevent hepatic destruction, portal hypertension, and cirrhosis[1].<br />

Over 35 million people in Asia are infected with Clonorchis Sinensis. In endemic areas such as<br />

Guangdong, China, over 78.5%-85% <strong>of</strong> the individuals are infected. Factors that contribute to the<br />

disease include lavatories that are built adjacent to fish ponds, domestic animal feces supplemented to<br />

the ponds to feed the fish, raw fish consumption, and the lack <strong>of</strong> education about the disease [2]. Of<br />

1521 people interviewed in Guangdong, 64% did not know about fluke disease, and those who did<br />

thought it was only a mild illness [3 ].<br />

Obtaining a thorough history and appropriate diagnostic testing in patients at risk for the disease is<br />

paramount to early recognition and treatment.<br />

Extensive Cardiac Tumor Arising from Renal Cell Carcinoma<br />

Elena Katz, MD Nataliya Mar, MD Solaiman Futuri, MD Dana Shani, MD<br />

INTRODUCTION: Secondary cardiac neoplasms occur 20-40 times more frequently than native tumors,<br />

most <strong>of</strong>ten originating from hematologic malignancies, or primary skin, lung and breast cancers.<br />

Metastases from renal cell carcinoma (RCC) are exceedingly rare. We report a case <strong>of</strong> an extensive<br />

cardiac tumor arising from RCC.<br />

CASE PRESENTATION: A 73-year old Hispanic male, who has not seen a physician in over 20 years,<br />

presented as an outpatient with new–onset <strong>of</strong> leg edema and dyspnea. Past medical, surgical and social<br />

histories were unremarkable. Review <strong>of</strong> systems was negative for any weight change, flank pain or<br />

hematuria. On physical exam the patient had decreased breath sounds at the lung bases and bilateral 2+<br />

pitting pedal edema. The relevant abnormal laboratory studies included a BUN <strong>of</strong> 53 ml/dL, creatinine <strong>of</strong><br />

1.83 mg/dL, AST <strong>of</strong> 58 U/L, ALT <strong>of</strong> 159 U/L, total bilirubin <strong>of</strong> 1.4 mg/dL, and platelets <strong>of</strong> 89 x10 3 uL.<br />

Urinalysis revealed 1+ proteinuria. An echocardiogram showed a mass within the right atrium. A cardiac<br />

computed tomography (CT) scan revealed a 5.0 by 4.0 cm right atrial mass with a 2.5 cm by 1.0 cm<br />

projection into the right ventricle. Subsequent CT angiography identified another 4.9 cm by 4.3 cm mass<br />

in the left kidney, with tumor thrombus extending through the circumaortic left renal vein into the<br />

inferior vena cava (IVC), right renal vein and the heart. Radiologic appearance was consistent with RCC.<br />

Liver cirrhosis and moderate ascites were also present. A radionuclide renal scan showed diminished<br />

renal function bilaterally, left (26%) worse than right (74%). The patient refused a tissue biopsy as well<br />

as any therapeutic intervention.<br />

DISCUSSION: RCC constitutes 3% <strong>of</strong> all adult malignancies and 90-95% <strong>of</strong> neoplasms arising from the<br />

kidney. Twenty-five to thirty percent <strong>of</strong> patients are asymptomatic at the time <strong>of</strong> diagnosis, with disease<br />

found incidentally on radiologic studies. A third <strong>of</strong> patients presents with metastases, involving the<br />

lungs, liver, bones, lymph nodes as well as the brain. Cardiac involvement is very rare. Only 5-10% <strong>of</strong><br />

RCCs develop a tumor that propagates into the renal vein or IVC with further extension into the right<br />

atrium in 1% <strong>of</strong> patients. This can clinically manifest with symptoms <strong>of</strong> decompensated heart failure as<br />

was seen in our patient. Thus, cardiac metastasis must not be overlooked in the differential for the<br />

cause <strong>of</strong> ventricular outlet obstruction in those presenting with symptoms <strong>of</strong> acute heart failure <strong>of</strong><br />

unclear etiology. Of note, the diagnosis in this case rested on multidetector CT images, which having<br />

97% specificity for predicting tumor presence in the renal vein and IVC are an accepted diagnostic<br />

modality.<br />

Catastrophic Antiphospholipid Antibody Syndrome with Reversible Dilated Cardiomyopathy: A Rare<br />

Association and Challenges in Treatment<br />

Jehanzeb Khan, MBBS Lisa Seo, Mohini Bollineni, Cheriyan Thomas, Ritesh Kumar, Karen Beekman<br />

INTRODUCTION: Catastrophic antiphospholipid antibody syndrome (CAPS) is a distinctly rare dramatic<br />

condition characterized by widespread thrombosis <strong>of</strong> small vessels, first described in 1992 by Ronald<br />

Asherson. Antiphospholipid antibody syndrome (APS) is associated with recurrent arterial and venous<br />

thrombosis. Infections, trauma, medication, or surgery can be identified in about half the cases as a<br />

trigger for CAPS. It is thought that cytokines are activated leading to a ‘cytokine storm’ with the<br />

potentially fatal consequence <strong>of</strong> organ failure. The mortality is extremely high (50%)when the disease<br />

accelerates to a catastrophic course. Less than 0.8% <strong>of</strong> all patients with APS present with a catastrophic<br />

form. CAPS by definition develops within a week and is characterized by multiorgan damage (three or<br />

more) and persistence <strong>of</strong> antiphospholipid antibody. This disorder has a predilection for the lung, brain,<br />

heart, and kidney. CAPS has also been rarely associated with thrombosis <strong>of</strong> the coronary arteries leading<br />

to dilated cardiomyopathy without evidence <strong>of</strong> ischemia.<br />

CASE PRESENTATION: A thirty one year old male presented to ER with hemoptysis for one day. Patient<br />

had no shortness <strong>of</strong> breath and no significant past medical history. CT angiogram <strong>of</strong> the chest revealed<br />

right lower lobe pulmonary embolism with multiple right lower lobe pulmonary infarcts. Anticoagulation<br />

initially started with IV heparin was discontinued later due to worsening hemoptysis. Vitals signs were<br />

stable except a temperature <strong>of</strong> 99F. A transthoracic echocardiogram (TTE) showed EF <strong>of</strong> 25% and left<br />

ventricular enlargement. The following day he complained <strong>of</strong> right arm numbness. MRI <strong>of</strong> the brain<br />

revealed multiple small acute and sub-acute infarcts at various levels. Hypercoagulable state work up<br />

was positive for lupus anticoagulant. Bilateral lower extremity duplex was negative for deep vein<br />

thrombosis. A bronchoscopy obtained later showed extensive bleeding. Evaluation for various<br />

autoimmune/connective tissue disorders and infections was also negative (including ANA and DS DNA).<br />

Patient later improved after treatment with steroids, heparin and cyclophosphamide. TTE obtained two<br />

months later showed improved ejection fraction with decreased left ventricular size.<br />

DISCUSSION: Our case depicts a young male with acute ischemic infarcts <strong>of</strong> the brain, pulmonary<br />

embolism and dilated cardiomyopathy with a persistently positive lupus anticoagulant, highly suggestive<br />

<strong>of</strong> CAPS. Treatment revolves around stemming the ‘cytokine storm’. Early diagnosis and aggressive<br />

therapy are essential because <strong>of</strong> extremely high mortality. Therapeutic management includes heparin,<br />

high dose steroids, cyclophosphamide, plasma exchange, intravenous immunoglobulin and prostacyclin.<br />

However a number <strong>of</strong> patients are refractory to treatment. Recent case reports show that the use <strong>of</strong><br />

Rituximab (Anti B Lymphocyte antibody), Defibrotide (Anti coagulant) and Eculizumab (Anti C5 antibody)<br />

have been effective in these refractory cases.<br />

A case <strong>of</strong> Paroxysmal nocturnal hemoglobinuria (PNH) resembling Thrombotic thrombocytopenic<br />

purpura (TTP): A diagnostic dilemma<br />

Hina Khan, MD Second Author: Namita Gupta, MD Third Author: Huichun Zhan, MD<br />

INTRODUCTION:PNH is a rare hematologic disease that presents with protean manifestations. It arises<br />

from an acquired mutation in the PIG-A gene in hematopoietic stem cells, leading to decreased synthesis<br />

<strong>of</strong> glycosylphosphatidylinositol anchors that bind to complement regulatory proteins. This causes<br />

increased susceptibility <strong>of</strong> red cells to complement mediated intravascular and extravascular hemolysis.<br />

We present a rare case <strong>of</strong> denovo PNH, posing as a diagnostic dilemma.<br />

CASE PRESENTATION: A 25-year-old African <strong>American</strong> male presented with worsening bilateral<br />

pleuritic chest pain and occipital headache <strong>of</strong> 3 days. He had fever up to 103F, dark urine and yellowish<br />

discoloration <strong>of</strong> eyes a week before presentation. He also noticed blood in stools and bleeding gums. He<br />

endorsed generalized weakness, fatigue, chronic intermittent headaches and shortness <strong>of</strong> breath on<br />

exertion for last 4 months. Physical exam revealed pallor, icterus and mild splenomegaly. Laboratory<br />

tests revealed pancytopenia [WBC count: 3400/cumm, Hb: 9.0 mg/dl, platelet count: 37,000/cumm],<br />

indirect hyper-bilirubinemia, low haptoglobin levels and elevated LDH levels [373 u/l]. The peripheral<br />

smear revealed schistocytes, macrocytic cells and increased reticulocytes. At this time a<br />

microangiopathic hemolytic process was high on the differential diagnosis. With negative Coomb’s test,<br />

suspicion for TTP was high. He met three <strong>of</strong> five classic symptoms in the TTP pentad and was started on<br />

plasmapheresis. No improvement in pancytopenia was observed after multiple days <strong>of</strong> plasmapheresis.<br />

Further testing revealed sickle cell trait. G6PD levels and ADAMS TS-13 activity levels were reported<br />

normal. Bone marrow biopsy showed marked erythroid hyperplasia with decreased myelocytic and<br />

megakaryocytic elements. Flow-cytometry and cytogenetics were unremarkable. CT scan performed in<br />

an attempt to rule out occult malignancy, revealed right lower lobe pulmonary embolus and<br />

splenomegaly. At this point, suspicion for PNH surfaced. PNH clones were seen in RBC [4.5% PNH III RBC]<br />

and WBC [17% monocytes and 2% granulocyte] with 95% CD59+ cells. Patient was started on steroids<br />

and later eculizumab with improvement in pancytopenia and resolution <strong>of</strong> pulmonary embolism.<br />

DISCUSSION: PNH is an acquired defect in complement cascade leading to chronic intravascular<br />

hemolysis with acute episodes, hemoglobinurea, pancytopenia and thrombosis. Venous thrombosis is<br />

seen in 85% <strong>of</strong> PNH patients. PNH may arise denovo or in association with acquired aplastic anemias.<br />

Since the clinical picture may overlap with other macroangiopathic hemolytic processes, initial diagnosis<br />

may present as a diagnostic dilemma and <strong>of</strong>ten lead to fatal outcomes from thrombosis. Above case<br />

emphasizes the importance <strong>of</strong> clinical suspicion for PNH in unexplained cytopenias and thrombosis. To<br />

our knowledge, this is also amongst the rare cases <strong>of</strong> PNH with sickle cell trait, which may also have<br />

contributed to increased risk <strong>of</strong> thrombosis.<br />

Effectiveness <strong>of</strong> virtual reality gaming technology using Wii® in maintaining function in the elderly: a<br />

pilot study.<br />

Staten Island, NY<br />

INTRODUCTION: The Wii® game-system provides the patient with a real world experience during their<br />

physical therapy sessions. This kind <strong>of</strong> virtual reality may motivate patients to complete exercises and<br />

provide a positive feedback to improve their performance. The utility <strong>of</strong> virtual reality game consoles<br />

had been studied in children and adolescents with cerebral paralysis and shown to improved adherence,<br />

exercise repetition, endurance and visual-perceptual processing. A recent meta-analysis concluded that<br />

virtual reality may be a potential and safe tool for stroke rehabilitation. The aim <strong>of</strong> the study is to assess<br />

the utility <strong>of</strong> virtual reality gaming console Wii® in maintaining the level <strong>of</strong> function in people age 80 and<br />

above.<br />

CASE PRESENTATION: Method: This prospective, interventional pilot study assessed the functional<br />

performance as measured by the Functional Independence Measure (FIM) and Fall Risk Assessment<br />

(FRA) scores. We enrolled 10 men and women who were referred for physical therapy at an outpatient<br />

rehabilitation center. These patients underwent a supervised exercise regimen using a Wii® Fit program<br />

consisting <strong>of</strong> three 30-minute exercise sessions per week for total <strong>of</strong> 6 weeks. FIM TM scores and FRA as<br />

measured by the Biodex Balance System were measured at the initial visit and at completion <strong>of</strong> the 6week<br />

program. The FIM score assesses areas <strong>of</strong> dysfunction in activities <strong>of</strong> daily living. Eighteen<br />

variables were graded using a seven-point scale and the level <strong>of</strong> independence was measured as follows:<br />

1-total assistance, 7-total independence. Maximal possible score was 126 points.<br />

The Biodex Balance System assesses neuromuscular control and estimates fall risk by quantifying the<br />

ability to maintain unilateral and bilateral postural stability on either a static or unstable surface. FRA<br />

scores higher than age dependent normative values suggest further assessment for lower extremity<br />

strength, proprioception, and vestibular or visual deficiencies. For patients aged 80 years and above, the<br />

normal FRA ranges from 1.6 - 3.5. A lower score indicates less fall risk.<br />

Results: 7 out <strong>of</strong> 10 patients completed the program. Mean FIM TM scores were maintained throughout<br />

the duration <strong>of</strong> the intervention and remained unchanged at completion <strong>of</strong> the exercise program as<br />

compared to the initial assessment (125.4). Mean score <strong>of</strong> the Biodex FRA decreased from 2.6 to 2.2 at 6<br />

weeks <strong>of</strong> therapy.<br />

DISCUSSION: A virtual reality gaming console, such as Nintendo Wii® may be an effective mode <strong>of</strong><br />

home-based physical therapy for elderly patients in maintaining their functional status.<br />

A CASE OF ADULT LEFT PULMONARY ARTERY AGENESIS THAT ALSMOST WENT UNDIAGNOSED<br />

Grace N LaTorre, DO, Ali Chaudhry, MD, Urmila Shivaram, MD<br />

INTRODUCTION: Unilateral pulmonary artery agenesis (UPAA) is a rare condition commonly associated<br />

with other congenital defects, such as Tetralogy <strong>of</strong> Fallot, atrial septal defect, coarctation <strong>of</strong> aorta, right<br />

aortic arch, and Eisenmenger’s syndrome when detected early in life. In these cases the left pulmonary<br />

artery is more <strong>of</strong>ten absent. Isolated UPAA is more commonly seen in adults and usually affects the right<br />

pulmonary artery. These patients are usually asymptomatic and are diagnosed accidentally after routine<br />

chest radiography or after presenting with non-specific symptoms such as respiratory tract infections,<br />

shortness <strong>of</strong> breath and hemoptysis.<br />

CASE PRESENTATION: A 54 year old African <strong>American</strong> female was admitted to our hospital with<br />

complaints <strong>of</strong> worsening <strong>of</strong> dyspnea on exertion & orthopnea. The patient’s symptoms initially<br />

presented three years ago and she underwent extensive evaluation including sleep studies, chest<br />

radiography, CT scan <strong>of</strong> chest and coronary catheterization leading to the diagnosis <strong>of</strong> sleep apnea and<br />

COPD. The patient was in good condition most <strong>of</strong> her life, with 3 term pregnancies finished with normal<br />

deliveries. She also supported elective bariatric surgery without complications. Physical exam revealed a<br />

morbidly obese women, with mild distress secondary to shortness <strong>of</strong> breath; chest and heart exam<br />

showed marked scoliosis <strong>of</strong> the thoracic spine with decreased bilateral breath sounds, normal hearts<br />

sounds and no murmurs; extremities with bilateral lower extremity edema. On this admission, CT scan<br />

<strong>of</strong> the chest interestingly revealed absence <strong>of</strong> the entire left pulmonary arterial system with marked<br />

hypoplasia <strong>of</strong> the left lung and evidence <strong>of</strong> chronic right heart strain. Echocardiogram showed severe<br />

pulmonary hypertension, severe right atrial and right ventricular enlargement with decreased systolic<br />

function. The patient was medically managed for fluid overload and pulmonary hypertension and as her<br />

disease progress she was later referred to Columbia University for further management <strong>of</strong> her right<br />

heart failure and heart & lung transplant evaluation. We concluded that the patient’s pulmonary arterial<br />

agenesis with pulmonary hypoplasia overtime led to this patient’s severe dextro-scoliosis and the<br />

development <strong>of</strong> pulmonary hypertension which both then resulted in her right heart failure.<br />

DISCUSSION: As previously mentioned UPAA is a rare condition with an estimated prevalence <strong>of</strong> 1 in<br />

300, 000. Approximately 170 patients with this disease have been described in the literature. UPAA<br />

may remain asymptomatic or misinterpreted for many years; the unspecific clinical signs may lead to<br />

late diagnosis and in some cases diagnosis may not be reached even after repeated imaging, as<br />

described in our case. The latter may be because the anomalies observed are attributed to old<br />

infections. Failure to recognize the malformation may lead to inappropriate treatment and delayed<br />

surgical intervention. In conclusion, it is important to suspect UPAA in patients presenting with nonspecific<br />

respiratory symptoms accompanied with chest x-ray findings such as decrease in size <strong>of</strong> the<br />

affected hemithorax and compensatory hyperinflation <strong>of</strong> the contralateral hemithorax, elevation <strong>of</strong><br />

ipsilateral diaphragm and ipsilateral shift <strong>of</strong> mediastinum and/or absence <strong>of</strong> pulmonary artery shadow<br />

or pulmonary markings on the affected side.<br />

Secondary Hypertrophic Pulmonary Osteoarthropathy in the setting <strong>of</strong> Primary Lung Adenocarcinoma<br />

and Latent Mycobacterium Tuberculosis Infection: A Case Report<br />

Philippe Leveille, M.D., Kim John D.O., Olga Filipova, M.D., Julie Kanvesky, M.D., Mark Sonneschine, D.O.<br />

INTRODUCTION: Hypertrophic Pulmonary Osteoarthropathy (HPOA) is a rare syndrome characterized<br />

by digital clubbing, synovitis with arthralgias, and periostosis <strong>of</strong> the tubular bones. Although HPOA has<br />

been known for more than 100 years, it remains poorly understood. Previously, both tuberculosis<br />

infections and primary lung malignancies have been individually reported to be associated with the<br />

syndrome. We present a case where a positive PPD screening was found to coexist with an underlying<br />

malignancy in the setting <strong>of</strong> hypertrophic pulmonary osteoarthopathy.<br />

CASE PRESENTATION: A 37-year-old, male, Honduran construction worker presented with a 3-month<br />

history <strong>of</strong> symmetric diffuse arthralgia, fever, night sweats, weight loss and digital clubbing. He was<br />

found to have a positive PPD and was admitted for further management. Chest X-ray showed evidence<br />

<strong>of</strong> pulmonary disease. Work-up for active tuberculosis was negative, but revealed a primary left upper<br />

lung, unifocal, adenocarcinoma with neuroendocrine features. The tumor size was noted to be 5.0 x 2.8<br />

x 2.6 cm, with no mention <strong>of</strong> a scar cancer. His social history was negative for smoking; and further<br />

history was unremarkable for risk factors. Incidental findings during his admission included a silent<br />

pneumothorax and a microcytic anemia. A staging PET-CT scan failed to reveal metastatic disease, thus<br />

the patient was indicated for tumor resection. The patient underwent primary surgical treatment with<br />

tumor resection by lobectomy without complications. Subsequently, the patient underwent adjuvant<br />

chemotherapy and radiation therapy for his malignancy and tolerated it well.<br />

DISCUSSION: This case may indicate the possibility <strong>of</strong> an association between the three<br />

diagnoses: latent tuberculosis, primary lung adenocarcinoma, and HPOA. This patient was without risk<br />

factors for malignancy, with a diagnosis <strong>of</strong> latent tuberculosis and a clinical manifestation <strong>of</strong><br />

HPOA. While it is possible that the concurrent finding <strong>of</strong> a positive PPD in our patient was merely<br />

incidental alongside his primary lung malignancy, the previously noted association <strong>of</strong> tuberculosis<br />

infections with hypertrophic pulmonary osteoarthropathy makes this case notable. It would be<br />

plausible to check acid-fast bacillus (AFB) smears <strong>of</strong> patients with initial diagnoses <strong>of</strong> primary lung<br />

adenocarcinoma presenting with HPOA to search for clues for the pathophysiology <strong>of</strong> the<br />

syndrome. This may help guide treatment for patients who do not have primary resection as a<br />

treatment option.<br />

HIGH ALTITUDE HYPOXIA AND SPLENIC INFARCTION<br />

Vivek A Lingiah, MD Additional Authors: Kwen Ortega MD, Madeeha Khan MD, Prasanta Basak MD,<br />

Stephen Jesmajian MD<br />

INTRODUCTION: Sickle cell anemia is characterized by abnormal hemoglobin molecules that deform<br />

and aggregate under deoxygenated conditions. Splenic infarction, or autosplenectomy, occurs in these<br />

patients after repeated vaso-occlusion <strong>of</strong> the splenic microvasculature. The etiology <strong>of</strong> these vasoocclusive<br />

crises is usually secondary to dehydration, infection, or hypoxia. However, high altitudes can<br />

also precipitate this condition. We present a case <strong>of</strong> splenic infarction in a patient after an airplane<br />

flight.<br />

CASE PRESENTATION: A 25 year-old male came to the ED with a 2 day history <strong>of</strong> left upper quadrant<br />

(LUQ) pain. He had recently flown 12 hours, and complained <strong>of</strong> abdominal pain since his return. The<br />

pain was associated with fever and chills. He took no home medications and had a history <strong>of</strong> sickle cell<br />

trait, without any painful crises since childhood. He denied smoking or drug use, and socially drank 1-2<br />

beers on weekends. On exam, he was in painful distress. Blood pressure was 154/91, pulse 118,<br />

respiration 20, temperature 98.8F and saturation 99% on room air. Breath sounds were clear. There was<br />

LUQ tenderness with mild guarding but no rebound tenderness. WBC was 18 and H/H was 12.1/37.4.<br />

Chemistry panel was normal, but D-Dimer was high (1301). Chest CT and lower extremity dopplers were<br />

negative for PE and DVT. CT abdomen showed considerable inflammation, consistent with splenic<br />

infarction. Blood cultures came back negative. Hemoglobin electrophoresis showed elevated<br />

Hemoglobin S (HbS) and Hemoglobin A2 (HbA2) (66.7% and 8.2%, respectively), confirming sicklethalassemia<br />

trait. The patient was started on ceftriaxone, IV fluids, supplemental oxygen and analgesics,<br />

with improvement in WBC count, fever and pain. He followed up with his hematologist, and was advised<br />

to avoid flying without supplemental oxygen.<br />

DISCUSSION: Airplanes usually fly at 35,000 feet. The aircraft cabin is pressurized, bringing the partial<br />

pressure <strong>of</strong> oxygen to what it would be at 8000 feet. At this altitude, there is about 25% less oxygen in<br />

the air than at sea level. With this decrease in oxygen, sickling <strong>of</strong> red cells could occur, especially in<br />

patients with higher percentages <strong>of</strong> HbS. Splenic crisis has been reported to occur in 4.3% <strong>of</strong> patients<br />

with Hb SS and in 23.5% patients with Hb S B-thalassemia after airplane travel. These patients should be<br />

aware <strong>of</strong> complications that can arise at high altitudes, and physicians should evaluate them for the<br />

need <strong>of</strong> in-flight supplemental oxygen.<br />

Bing Neel Syndrome- A Rare Complication <strong>of</strong> Waldenstrom’s Macroglobulinemia<br />

Akshiv Malhotra, MBBS Others: Toni Pacioles, MD Teresa Gentile, MD<br />

INTRODUCTION: Bing Neel (BN) syndrome is a very rare complication <strong>of</strong> Waldenstrom’s<br />

Macroglobulinemia (WM) that should be considered in patients with neurologic symptoms and a history<br />

<strong>of</strong> WM. Neurologic complications occur in 25% cases <strong>of</strong> WM, but are most commonly due to serum<br />

hyperviscosity syndrome and immune related neuropathy. Direct malignant lymphoid infiltration <strong>of</strong> the<br />

CNS, the so called Bing Neel syndrome is extremely rare.<br />

CASE PRESENTATION: 70 year old female presented to the Emergency Department(ED) with<br />

worsening left upper extremity weakness, dysarthria and confusion.<br />

Her past medical history was significant for WM diagnosed 1 year ago, breast cancer diagnosed 11 years<br />

ago, status post lumpectomy, radiation and Tamoxifen. About a year ago, she was noted to have anemia<br />

and paraprotein in her blood and underwent a bone marrow biopsy which showed a lymphoplasmacytic<br />

infiltrate. She then underwent CT scans to look for enlarged lymph nodes. She was found to have a mass<br />

<strong>of</strong> the left kidney which on biopsy showed Lymphoplasmacytic lymphoma with an IgM monoclonal<br />

protein (WM). She was treated with 4 cycles <strong>of</strong> Rituximab to which she responded well. However, she<br />

started having intermittent confusion and balance problems and now, presented to the ED with left<br />

upper extremity weakness, dysarthria and confusion. The patient was admitted to the neurology service.<br />

The symptoms resolved within 6 hours <strong>of</strong> onset. She underwent CT <strong>of</strong> the head without contrast which<br />

showed no evidence <strong>of</strong> acute bleed or infarct. MRI <strong>of</strong> the brain showed dural enhancement. Lumbar<br />

puncture was performed which showed Protein <strong>of</strong> 768 mg/dl and White count <strong>of</strong> 108/cu mm with 100%<br />

monocytes. The cytopathology report and flow cytometry came back consistent with previously<br />

diagnosed B cell lymphoma ( Lymphoplasmacytic lymphoma). Dexamethasone 4 mg every 6 hours was<br />

started. An intraventricular reservoir was placed and intrathecal Methotrexate was started twice a week<br />

for 8 cycles. The CSF cleared up with no evidence <strong>of</strong> malignancy. She was then treated with craniospinal<br />

irradiation and has remained in remission for 4 months.<br />

DISCUSSION: BN syndrome is defined as WM with perivascular infiltration <strong>of</strong> small lymphocytes,<br />

lymphoplasmacytoid cells, and plasma cells in the CNS. BN syndrome refers specifically to the<br />

involvement <strong>of</strong> perivascular infiltrates rather than stroke or hemorrhage due to hyperviscosity.<br />

Symptoms may include seizures, confusion, cognitive decline, headache, blurry vision, pain, numbness,<br />

paresthesias, hearing loss, or weakness. Serum laboratory tests show macroglobulinemia, normocytic<br />

anemia, IgM kappa or lambda light chain restriction. CSF analysis shows lymphocytic pleocytosis <strong>of</strong> 100-<br />

500 cells/cu mm, elevated protein 40-2000 mg/dl and CD20+ lymphoplasmacytoid cells in flow<br />

cytometry and cytology. MRI shows T2/FLAIR hyperintensity and gadolinium enhancement. Remission<br />

in BN syndrome has been reported with the use <strong>of</strong> intrathecal Methotrexate alone, or with radiation<br />

therapy.<br />

THE G.I.S.T. OF NEUROFIBROMATOSIS<br />

Akshiv Malhotra, MBBS Others: Jonathan Wright, MD Ajeet Gajra, MD<br />

INTRODUCTION: Neur<strong>of</strong>ibromatosis type 1 (NF1) , also known as Von- Recklinghausen’s disease is<br />

amongst the most commonly transmitted hereditary autosomal dominant diseases, with an estimated<br />

birth incidence <strong>of</strong> 1:3,000. Loss <strong>of</strong> NF1 tumor suppressor gene on chromosome 17 leads to the<br />

development <strong>of</strong> benign and malignant tumors in NF1. In addition to cutaneous, s<strong>of</strong>t tissue, and visceral<br />

(plexiform) neur<strong>of</strong>ibromas, this syndrome is associated with several types <strong>of</strong> gastrointestinal (GI) and<br />

abdominal tumors. Here we present the case <strong>of</strong> a patient with NF1 who was incidentally found to have<br />

an extraintestinal Gastro-Intestinal Stromal Tumor (GIST).<br />

CASE PRESENTATION: A 64-year-old man with known NF1 during preoperative workup for a CABG was<br />

incidently noted to have a large inhomogeneous pelvic mass with dimensions <strong>of</strong> 9 cm x 10 cm x 7.8 cm<br />

on a CT abdomen/pelvis. Biopsy <strong>of</strong> the mass showed palisaded appearing long spindle cells. On<br />

immunohistochemical testing, S-100 was negative (ruling out schwannoma) and there was strong and<br />

diffuse positivity for CD117( KIT) and CD34 indicating a GIST.<br />

The tumor was considered to be marginally resectable, so neoadjuvant treatment with Imatinib 400 mg<br />

daily was started to decrease the tumor size preoperatively. After three months on the repeat CT<br />

abdomen/pelvis multiple foci <strong>of</strong> air were seen in the mass, suggestive <strong>of</strong> necrosis though the size<br />

remained stable at 11 X 9.7 X 7.7 cm. His tumor was then surgically resected en-bloc. Large cavity was<br />

noted within the tumor along with fistula formation necessitating partial excision <strong>of</strong> small intestine.<br />

After the surgery he was restarted on Imatinib 400 mg daily for 36 months<br />

DISCUSSION: Extra-intestinal GIST is a very rare entity, accounting for < 5% <strong>of</strong> cases <strong>of</strong> GIST. There is a<br />

known correlation between NF1 and GIST. GIST develops in 7% <strong>of</strong> patients with NF1, although the<br />

incidence <strong>of</strong> GIST in the general population is 1.5/100,000/year. NF1 patients tend to develop GIST at a<br />

younger age (median 49 years) than sporadic GIST (56 years). This brings forward a need to formulate<br />

guidelines to screen for GIST in patients with NF1 at an earlier age. GIST may be associated with<br />

gastrointestinal bleed, perforation or obstruction as demonstrated by pathological findings in our case.<br />

Imatinib has greatly enhanced outcomes in patients with GIST.<br />

AN UNUSUAL CAUSE OF HEADACHE<br />

Sandhya Manohar, MD Marie Louies Lamsen MD, Prasanta Basak MD, Stephen Jesmajian MD. Sound<br />

Shore Medical Center <strong>of</strong> Westchester and New York Medical <strong>College</strong>.<br />

INTRODUCTION:Colloid cysts are benign congenital tumors that usually arise from the anterior third<br />

ventricle,<br />

posterior to the foramen <strong>of</strong> Monro. These cysts have also been reported to frequently arise in<br />

the septum pellucidum, the fourth ventricle, and the sella turcica. They are usually filled with<br />

gelatinous material and cholesterol crystals. The epithelium lined cysts may lead to acute<br />

obstructive hydrocephalus, increased intracranial pressure, and rarely, intracystic hemorrhage.<br />

Approximately 0.5-1% <strong>of</strong> all primary brain tumors and 15-20% <strong>of</strong> all intraventricular masses are<br />

colloid cysts.<br />

CASE PRESENTATION: A 46 year old female came to the ER complaining <strong>of</strong> severe headaches for 4<br />

days. Her<br />

headache was localized to the top <strong>of</strong> her head, with radiation to the back <strong>of</strong> her neck. She<br />

described the headache as pressing, 8-9/10 intensity, lasting from minutes to hours, and<br />

aggravated by stress. She found partial, relief with Ibupr<strong>of</strong>en and heating pads. There was no<br />

associated nausea, photophobia, tinnitus, vertigo, or weakness. There was no prior history <strong>of</strong><br />

severe headaches or migraine. On examination she was anxious, not in any distress, with BP<br />

98/63, pulse 88/min, RR 18/min, temp 97.8F and Spo2 99%. Neurological examination including<br />

fundoscopy was normal. Her routine blood work was unremarkable. A CT head without contrast<br />

showed an 8.5mm rounded circumscribed hyperdense structure in the region <strong>of</strong> foramen <strong>of</strong><br />

Monro, most consistent with a colloid cyst, along with enlargement <strong>of</strong> the left lateral ventricle<br />

and transudation <strong>of</strong> fluid, suggestive <strong>of</strong> periventricular interstitial edema. Neurology was<br />

consulted and she was referred to a neurosurgeon for cyst removal.<br />

DISCUSSION: Although these tumors are considered congenital, their presentation in childhood is rare.<br />

The<br />

tumors are usually symptomatic in patients aged 20-50 years. With the advent <strong>of</strong> CT scanning<br />

and MRI, the number <strong>of</strong> diagnosed asymptomatic colloid cysts has increased. Though there<br />

was dilatation <strong>of</strong> the lateral ventricle, our patient did not have symptoms suggesting normal<br />

pressure hydrocephalus (eg, dementia, gait disturbance, urinary incontinence). If patients are<br />

too ill to tolerate surgical resection, cerebrospinal fluid diversion, <strong>of</strong>ten requiring bilateral shunts,<br />

may be considered. Our case highlights the importance <strong>of</strong> a head CT in late onset persistent<br />

headaches.<br />

EIKENELLA CORRODENS: A RARE CAUSE OF SEPTIC ARTHRITIS OF THE HIP<br />

Sandhya Manohar, MD Diana De Jesus MD, Esther Kwon, Prasanta Basak MD, Jeffrey Lederman MD,<br />

Stephen Jesmajian MD. Sound Shore Medical Center <strong>of</strong> Westchester and New York Medical <strong>College</strong>.<br />

INTRODUCTION:Over 90% cases <strong>of</strong> septic arthritis are due to Staphylococci or Streptococci infections.<br />

Septic arthritis with Eikenella corrodens as the etiological organism has been rarely reported. The<br />

pathogenesis is usually a “fight bite” injury to the hand or the metacarpal phalangeal joint, through<br />

which the organism gets inoculated. We present a case <strong>of</strong> septic arthritis with Eikenella corrodens and<br />

Streptococcus intermedius, without an obvious portal <strong>of</strong> entry.<br />

CASE PRESENTATION: 66 year old female complained <strong>of</strong> severe lower back pain. The pain was<br />

constant, rated 10/10, radiating down the left leg and worsened by movement. There was no history <strong>of</strong><br />

trauma or recent dental work. She did not complain <strong>of</strong> weakness, sensory symptoms or incontinence.<br />

On admission, she was afebrile but tachycardic at 107bpm, with BP <strong>of</strong> 147/98 mm Hg. She had restricted<br />

range <strong>of</strong> movement, on the left leg due to extreme pain. The left groin was tender to palpation. The rest<br />

<strong>of</strong> the physical exam including neurologic exam was unremarkable. Laboratory tests showed WBC<br />

17000/cu mm, with polymorphs <strong>of</strong> 80. Chemistry panel was normal. CXR was negative. Lumbosacral<br />

spine MRI showed unremarkable age related changes. Pelvic MRI showed moderate left hip joint<br />

effusion with adjacent medial muscle edema. On the second day <strong>of</strong> admission she developed a fever <strong>of</strong><br />

101.5F. Blood cultures were sent. CT guided aspiration <strong>of</strong> the left hip joint was done. The joint fluid<br />

showed protein 3 g/dl, glucose 16 mg/dl, WBC 214,500/cu mm with gram stain showing both gram<br />

positive cocci and gram negative bacilli. Empiric treatment with Ceftazidime and Vancomycin was<br />

started. Transthoracic echocardiogram showed hyperdynamic LV, and no vegetations. Cultures from<br />

joint fluid grew Streptococcus intermedius and Eikenella corrodens. Blood cultures grew Streptococcus<br />

intermedius. She was advised to undergo a trans esophageal echocardiogram, but the patient refused<br />

any further work up. A PICC line was inserted and IV ceftriaxone given for 4 weeks followed by 4 weeks<br />

<strong>of</strong> oral antibiotics.<br />

DISCUSSION: Both Eikenella corrodens and Streptococcus intermedius are commensals <strong>of</strong> the human<br />

mouth and upper respiratory tract. There appears to be an association between Streptococcus and<br />

Eikenella corrodens, which seem to frequently co-infect. Mixed infection with these organisms causes an<br />

exponential increase in growth, as compared to an infection with Eikenella alone. To the best <strong>of</strong> our<br />

knowledge, this is the first case report <strong>of</strong> Eikenella septic arthritis <strong>of</strong> the hip without an obvious port <strong>of</strong><br />

entry.<br />

LYMPHANGIOLEIOMYOMATOSIS (LAM) or PULMONARY LANGHERHANS CELL HISTIOCYTOSIS (PLCH)? A<br />

CHALLENGING DIAGNOSIS.<br />

Maryah Mansoor Scott Pompa Thomas Kilkenny Maryah Mansoor<br />

INTRODUCTION: CASE PRESENTATION: A 24 year old Caucasian woman presented with diffuse left<br />

sided chest pain and shortness <strong>of</strong> breath. The pain was sharp, non-radiating, pleuritic, and began acutely<br />

while sitting at her computer. Patient reported a chronic nonproductive cough. The patient had a 5 pack<br />

year smoking history. Her past medical history was significant for asthma since the age <strong>of</strong> 13. Family<br />

history was unremarkable. The patient’s oxygen saturation was 96% on room air and EKG showed sinus<br />

tachycardia. Lab work including complete blood count and metabolic pr<strong>of</strong>ile was within normal limits<br />

(WNL). Chest X-ray (CXR) showed interstitial lung disease, bilateral pneumothorax, left greater than<br />

right. The patient was kept on 100% non rebreather. A left side pig tail catheter was placed with<br />

continuous suction and later due to expansion <strong>of</strong> the right sided pneumothorax a right sided pigtail<br />

catheter was placed. High resolution computed tomography (HRCT) <strong>of</strong> he chest was performed, which<br />

demonstrated diffuse bilateral spherical and lobulated thin wall cysts consistent with<br />

lymphangioleiomyomatosis (LAM). An autoimmune workup for lupus and a1-antitrypsin deficiency was<br />

negative. Renal ultra sound and echocardiogram were WNL. Based on the presentation and HRCT,<br />

primary diagnosis <strong>of</strong> LAM was made. The patient was stabilized in the ICU and was later transferred to<br />

the city's LAM center. Lung biopsy was performed at the LAM centre revealed a definitive diagnosis <strong>of</strong><br />

Pulmonary Langherhans Cell Histiocytosis (PLCH).<br />

DISCUSSION: PLCH and LAM are rare lung diseases with unknown incidence and prevalence; both<br />

diseases affect young adults and Caucasians most frequently. PLCH predominately affects patients aged<br />

20 to 40 with equal gender distribution while LAM affects women <strong>of</strong> childbearing<br />

age. HRCT findings both diseases show multiple cysts, while PLCH may also have nodules with middle to<br />

upper lobe predominance and interstitial thickening. Due to these similarities it is <strong>of</strong>ten challenging to<br />

diagnose these disease entities clinically. Hence tissue confirmation by biopsy with immunostaining is<br />

required for definitive diagnosis. Being uncommon, both LAM and PLCH are <strong>of</strong>ten misdiagnosed as<br />

asthma and treated with bronchodilators untill the patient presents with complications (as in this case).<br />

Recurrent pneumothorax, pulmonary hypertension, diabetes insipidus, and malignancy are common<br />

complications <strong>of</strong> PLCH. Where as complications <strong>of</strong> LAM include spontaneous pneumothorax,<br />

chylothorax, chylopericardium. The treatment for PLCH should focus on smoking cessation.<br />

Immunosuppressive therapy such as glucocorticoids and cytotoxic agents are <strong>of</strong> limited value. No<br />

therapy has been proven beneficial for the treatment <strong>of</strong> LAM, however lung transplant should be<br />

considered in advanced progressive disease.<br />

LAM and PLCH although being rare should be considered a differential diagnosis in patients with<br />

spontaneous bilateral pneumothorax.<br />

BACK PAIN FROM THE TROPICS<br />

Maryah Mansoor Ayesha Siddiqui Neville Mobarakai Maryah Mansoor<br />

INTRODUCTION: CASE PRESENTATION: A 47 year old lady was sent to our institution by her PMD for<br />

evaluation <strong>of</strong> ataxia, gradually worsening bilateral leg weakness and numbness for 3 years. She also<br />

reported low back pain, paraesthesia <strong>of</strong> legs, progressive urinary incontinence and constipation. The<br />

patient had no history <strong>of</strong> trauma, fever, headache, seizure or other neurological symptoms. Review <strong>of</strong><br />

other systems was negative. The patient had no significant family history, sick contacts or any drug<br />

abuse. Her back pain was only partially relieved with analgesics. Her vitals were stable. Neurological<br />

exam was significant for decreased power in both lower extremities (3/5) with spasticity, hyper reflexia<br />

and non sustained ankle clonus. Gait was unsteady. Anal sphincter tone was normal. Rest <strong>of</strong> the<br />

neurological exam was normal.<br />

Further workup was pursued to rule out demyelination, infectious, inflammatory or autoimmune<br />

etiology. Investigations revealed normal hemogram, serum chemistry, vitamin B12, folate level, HbA1c<br />

and urinalysis. ESR was 8mm/hr; rheumatoid factor, RPR, anti nuclear antibody, ACE levels, lyme<br />

serology and antiphospholipid antibody were negative. CSF analysis was normal. MRI brain, cervical,<br />

thoracic and lumbosacral spine was unremarkable for myelopathy or demyelination.<br />

On further inquiry, patient revealed that she was originally from Ecuador and had settled in USA for 20<br />

years. Serum Human T cell lymphotropic virus type 1 (HTLV1) serology was also sent which came back<br />

positive. Patient was <strong>of</strong>fered an HIV test which she declined.<br />

Based on the clinical picture and serology, diagnosis <strong>of</strong> tropical spastic paralysis (TSP) or HTLV1<br />

associated myelopathy (HAM) was made. The patient was started on a short course <strong>of</strong> high dose<br />

intravenous steroids followed by oral prednisone taper. The patient was then referred for in-house<br />

rehabilitation with which she made gradual progress over a few months.<br />

DISCUSSION: There are various pathologies that affect the spinal cord including traumatic, vascular,<br />

autoimmune, neoplastic or infectious etiologies. Human T-cell lymphotropic virus type I (HTLV1) is<br />

known to cause adult T cell leukemia/lymphoma and slowly progressive neurological disease called<br />

HTLV1 associated myelopathy (HAM) or Tropical Spastic Paralysis (TSP) comprising <strong>of</strong> spastic paraparesis<br />

and urinary disturbance. It is characterized by inflammation <strong>of</strong> spinocerebellar, corticospinal and<br />

spinothalmic tracts with relative sparing <strong>of</strong> the posterior columns. HAM/TSP is endemic in Japan,<br />

Caribbean, South America, Middle East, but comparatively rare in USA hence is <strong>of</strong>ten overlooked. There<br />

is no definite treatment recommended for this disease, however steroids with their anti inflammatory<br />

effects are thought to be useful. While trauma, vascular, neoplastic entities are common causes <strong>of</strong> back<br />

pain with bowel and bladder malfunction, Tropical Spastic Paralysis (TSP) should be considered a<br />

differential diagnosis in immigrants from South America, Japan and other tropical areas.<br />

Blood pressure roller coaster: pheochromocytoma presenting with cyclic hypertensive crises and severe<br />

hypotension.<br />

Carlos Martinez-Balzano, MD. Robert Carhart, MD.<br />

INTRODUCTION: Cases <strong>of</strong> pheochromocytoma presenting with severe hypotension are extremely rare<br />

and their adequate management is unclear.<br />

CASE PRESENTATION: A 59-year-old Caucasian man presented with palpitations, diaphoresis,<br />

headache, nausea, and musculoskeletal pain. During examination, he had two cluster episodes with<br />

tachycardia (130 bpm) and hypertension (200/110 mmHg); he was also hyperreflexic and had<br />

orthostatic hypotension. He was admitted for a suspected pheochromocytoma. EKG showed sinus<br />

tachycardia without ST-segment changes. Echocardiogram demonstrated hyperdynamic ventricles and<br />

low EF (20-25%) thought to be secondary to tachycardic cardiomyopathy. BMP showed acute kidney<br />

injury with a BUN:creatinine ratio > 20:1 caused by kidney hypoperfusion and possible volume<br />

depletion. Treatment with IV normal saline (100 mL/h) and labetalol was started. Abdominal CT showed<br />

a large tumor in the right adrenal gland. Overnight, severe hypotension occurred (68/40 mmHg) which<br />

barely responded to 6L <strong>of</strong> IV fluids and required IV phenylephrine infusion. Intubation for airway<br />

protection was done. CK, CK-MB and troponin-T returned elevated and heparin infusion was started.<br />

Subsequent echocardiogram showed a normal EF without akinetic areas confirming the suspicion <strong>of</strong><br />

tachycardic cardiomyopathy and suggesting that the elevated CK-MB and troponin were systemic in<br />

origin. During the next 2 days, cyclic episodes <strong>of</strong> hypertensive crisis followed by hypotension occurred,<br />

and were treated with IV phentolamine infusion or pressor support, respectively. After that interval,<br />

fluctuations stopped and the pattern changed to persistent hypotension. Phenylephrine was slowly<br />

tapered and after 4 days was not required. The patient was awake and without major neurologic<br />

sequelae after extubation. A 24h urine collection revealed norepinephrine and epinephrine levels <strong>of</strong> 687<br />

µg and 1829 µg. Doxazosin and metoprolol were started and the patient was discharged home. One<br />

week after, he underwent surgery with excision <strong>of</strong> the pheochromocytoma with multiple necrotic areas,<br />

confirmed by histology.<br />

DISCUSSION: Pheochromocytoma can cause orthostatic hypotension, however, severe<br />

hypotension is very rare and few cases have been reported. A cyclic pattern <strong>of</strong> severe hypertension and<br />

hypotension has been seen in these cases which were all caused by epinephrine-secreting tumors. The<br />

hypothesis is that excessive epinephrine release leads to decreased circulating volume and<br />

vasoconstriction which decrease cardiac output and cause further catecholamine release. The resultant<br />

hypertension activates the baroreceptor reflex causing a hypotensive response which is worse in the<br />

setting <strong>of</strong> contracted volume. Another hypothesis is that tumor necrosis leads to massive catecholamine<br />

release followed by acute withdrawal causing hypotension, which could explain the persistent late<br />

hypotensive phase in our patient. Our case describes an unusual and not well-understood clinical<br />

presentation <strong>of</strong> pheochromocytoma. Furthermore, therapeutic recommendations for these cases are<br />

obscure and require further research since they present with life-threatening complications.<br />

Campylobacter Fetus Bacteremia In A Young Healthy Adult Transmitted By Khat Chewing<br />

Carlos Martinez-Balzano, MD. Patrick J. Kohlitz, MD. Preeti Chaudhary, MD. Housam Hegazy, MD.<br />

INTRODUCTION: Campylobacter fetus is a pathogen affecting almost exclusively patients with<br />

immunosuppression and chronic debilitating diseases. We report the case <strong>of</strong> a healthy young man with<br />

C. fetus bacteremia presenting with fever, hypotension and meningitis.<br />

CASE PRESENTATION: A 28-year-old healthy man presented with fever, chills, decreased appetite,<br />

night sweats, diarrhea and headache with photophobia for two days. He was a college student in an<br />

urban setting without any recent travel history. Physical examination revealed mild dehydration. CBC<br />

and stool examinations were normal. CSF analysis showed lymphocytosis (170 x 10 9 cells/L) with normal<br />

protein and glucose levels. He was discharged home receiving symptomatic treatment. After two days,<br />

the blood cultures were growing gram-negative rods and the patient was called back to the hospital. He<br />

had hypotension that was managed with intravenous fluids. Endocarditis was ruled out by TEE. CSF<br />

cultures and viral tests were negative. Phenotypic properties <strong>of</strong> the bacteria growing in four separate<br />

blood cultures drawn at different times, identified them as Campylobacter spp., confirmed as C. fetus<br />

subspecies fetus by analysis <strong>of</strong> 16S rDNA sequence. Although CSF cultures were negative, we believe the<br />

same microorganism caused the meningitis. Subsequent studies showed normal immunoglobulin levels<br />

and negative HIV serology. The patient denied ingestion <strong>of</strong> undercooked food, unpasteurized milk,<br />

contaminated water or close animal contact. He disclosed to be a frequent user <strong>of</strong> khat, which<br />

represents the most likely source <strong>of</strong> transmission. The patient received cipr<strong>of</strong>loxacin and azithromycin<br />

with adequate clinical improvement. After six months, he remains asymptomatic.<br />

DISCUSSION: Campylobacter fetus commonly affects cattle and sheep. Systemic disease in humans<br />

caused by this bacterium is severe and almost invariably associated with immunosuppression. Thus, C.<br />

fetus bacteremia in immunocompetent adults is extremely rare and only four cases have been reported.<br />

To our knowledge, this is the first case <strong>of</strong> C. fetus bacteremia in an immunocompetent man reported in<br />

the USA and also the first one linked to khat use.<br />

Khat is a plant that has been used for centuries in the Horn <strong>of</strong> Africa and the Arabian Peninsula. It<br />

contains the alkaloid cathionine and is cultivated in circumstances that favor contact with animal feces;<br />

its young leaves are picked freshly and transported in moist conditions to retain their potency. Our<br />

patient chewed the leaves unwashed for many hours, likely introducing the bacteria into his<br />

gastrointestinal tract. Khat is not associated with immunosuppression; to the contrary, it increases IL-2<br />

production, total lymphocyte and CD4 counts, which suggest that our patient was not<br />

immunocompromised by using it.<br />

Our case suggests that C. fetus is a pathogen that can affect not only immunosupressed patients but<br />

healthy individuals as well. Also, as new lifestyles are adopted, khat should be considered as a risk factor<br />

for the introduction <strong>of</strong> infectious diseases.<br />

Gluteal Abscess Formation After Concurrent Intramuscular Steroid and Heroin Injection<br />

Asad Mohammad, DO Second Author: Babak T<strong>of</strong>ighi, MD Third Author: Robert Graham, MD<br />

INTRODUCTION:Over one million individuals in the United States, have or continue to use anabolicandrogenic<br />

steroids. Abscesses and other related complications <strong>of</strong> intramuscular (IM) injection <strong>of</strong><br />

anabolic-androgenic steroids (AAS) have been well-documented in the literature. However cases <strong>of</strong><br />

concurrent use <strong>of</strong> AAS and heroin have yet to be reported. We present a case <strong>of</strong> abscess formation in a<br />

29 year-old female physical trainer reporting daily injections <strong>of</strong> AAS and heroin mixtures for four<br />

months.<br />

CASE PRESENTATION: A 29 year old caucasian female presented to the emergency department<br />

complaining <strong>of</strong> severe right buttock pain, described as a throbbing and burning sensation. Her symptoms<br />

began approximately two days prior, become progressively worse to the point that she could barely<br />

ambulate or move her right lower extremity. She noticed warmth, redness, and tenderness along the<br />

right buttock area that had now spread to her proximal posterior thigh. She denied fevers or chills. She<br />

did admit to regular injection <strong>of</strong> anabolic steroids and heroin into the right buttock area. Physical exam<br />

revealed erythema, tenderness, edema, and warmth along the right buttock area. Some fluctuance was<br />

also noted. CT scan <strong>of</strong> the pelvis revealed extensive subcutaneous edema <strong>of</strong> the lower back, and a large<br />

fluid collection superficial to the right gluteus muscles measuring 8.1 x 4.1 cm consistent with an<br />

evolving abscess. Edema extended inferiorly along the right gluteal region and lateral aspect <strong>of</strong> the<br />

proximal thigh.<br />

The surgery team performed an incision and drainage <strong>of</strong> the buttock abscess and she was discharged to<br />

home with oral antibiotics. Cultures were sent to the lab, which eventually returned positive for MRSA.<br />

DISCUSSION: Buttock injections <strong>of</strong> parenteral medications can sometimes result in the formation <strong>of</strong><br />

calcified granulomas, abscesses, vascular and nerve damage, and focal myopathies. Heroin injection has<br />

been shown to cause the above pathologies, and the concomitant injection <strong>of</strong> both heroin and anabolic<br />

steroids can also result in the similar complications. Such a combination may predispose patients to<br />

abscesses by inducing s<strong>of</strong>t-tissue ischemia exacerbated with nonsterile injection techniques. Education<br />

and close clinic follow-up is needed to prevent complications among users. In addition, epidemiological<br />

surveys <strong>of</strong> use patterns in athletes and trainers may help identify clusters at high risk <strong>of</strong> similar<br />

complications.<br />

Treatment <strong>of</strong> Hemosuccus Pancreaticus via ERCP: an uncommon but effective treatment<br />

Najul, Jose E. MD Kim, Sang MD Gutierrez, Cristina MD<br />

INTRODUCTION:Hemosuccus pancreaticus (HP) is a rare cause <strong>of</strong> gastrointestinal bleed (GIB). We<br />

describe the case <strong>of</strong> a patient with HP who was successfully managed with ERCP, a failry uncommon<br />

therapeutic approach.<br />

CASE PRESENTATION: A 56-year-old female was admitted to our hospital with pancreatitis and<br />

choledocolithiasis. ERCP with sphincterectomy and pancreatic duct stent placement improved her<br />

symptoms at the time. Fourteen days after discharge, the patient presented with hematemesis,<br />

hypotension, and hemoglobin <strong>of</strong> 5g/dl. Emergent upper endoscopy showed a clean papillotomy site, and<br />

active bleeding from the pancreatic duct orifice. Hemostasis was attempted with epinephrine injection<br />

and placement <strong>of</strong> Resolution clips. Post procedure the patient continued to have blood loss and<br />

required multiple transfusions. Repeat CT angiograms failed to show any aneurysms <strong>of</strong> the hepatic or<br />

splenic arteries or any other active bleeding sources. As embolization was not an option and surgery<br />

was reluctant to pursue any intervention, including partial and/or total pancreatectomy, ERCP was<br />

repeated. Active bleeding from aneurismal-like dilation <strong>of</strong> the pancreatic duct in the head <strong>of</strong> the<br />

pancreas was observed. The pancreatic duct was injected with epinephrine and ballooned to<br />

tamponade. When hemostasis was achieved, four pancreatic duct stents were deployed to maintain<br />

hemostasis. One month after discharge, a repeat ERCP with Spyglass pancreatoscopy was performed to<br />

determine the etiology <strong>of</strong> the HP. Pancreatoscopy revealed inflamed friable tissue in the pancreatic<br />

duct. Biopsies revealed marked inflammation with erosion and granulation tissue with reactive<br />

epithelial changes. There was no evidence <strong>of</strong> malignancy.<br />

DISCUSSION: HP was first described in 1931 and accounts for 1.4% <strong>of</strong> upper GIB cases requiring<br />

emergent endoscopy. Chronic pancreatitis, pancreatic malignancy, and pancreatic duct stones are<br />

commonly associated. Embolization through angiography is usually the preferred treatment. In our case,<br />

multiple angiograms failed to show the site <strong>of</strong> bleeding or aneurysms and a surgical approach was<br />

deemed to drastic. Therefore, ERCP with the injection <strong>of</strong> epinephrine, tamponade with a balloon, and<br />

placement <strong>of</strong> stents in the pancreatic duct was utilized and was successful.<br />

HP is a rare cause <strong>of</strong> GIB and due to its scarce nature it can easily be overlooked and mistreated. It is <strong>of</strong><br />

utmost importance that internists work in coordination with other specialists in identifying, diagnosing,<br />

and treating this pathology.<br />

INTRODUCTION: Fever and hepatitis in immunocompetent adults are usually attributed to common<br />

hepatotrophic viruses, namely hepatitis A, B and C. However, the less common viral hepatitides can also<br />

cause severe hepatitis in immunocompetent adults.<br />

CASE PRESENTATION: A 52-year-old female was admitted for intermittent fever for one week. This<br />

was accompanied by generalized muscle pains, upper abdominal and back pains. She had a history <strong>of</strong><br />

hypoparathyroidism. Her vital signs were temperature 102°F, heart rate 100 beats per minute, blood<br />

pressure 118/75mmHg and respiratory rate <strong>of</strong> 18 breaths per minute. The rest <strong>of</strong> her physical<br />

examination was unremarkable. She had normal blood count, chemistry, chest x-ray and urinalysis. Her<br />

liver enzymes were newly elevated, AST 739, ALT 955 and ALP 170, with normal bilirubin and<br />

international normalized ratio. The acetaminophen and alcohol levels, hepatitis A, B, C and HIV<br />

antibodies were negative. Hepatobiliary ultrasound, computerized tomography scans <strong>of</strong> the chest,<br />

abdomen, pelvis and echocardiogram were normal. Following admission, she developed diarrhea and<br />

was empirically treated with antibiotics pending stool studies. The diarrhea resolved spontaneously. She<br />

continued to have temperature spikes ranging between 102 and 104 o F despite anti-pyretics. Blood,<br />

urine and stool cultures yielded no pathogens. Work-up for non-infectious causes <strong>of</strong> hepatitis was<br />

negative. Tests for less common viral hepatitis such as Herpes Simplex, Epstein Barr and<br />

Cytomegalovirus were subsequently done. All were negative except for Cytomegalovirus IgM titer <strong>of</strong><br />

2.15 (normal value: 0.00-0.89) with Cytomegalovirus IgG titer <strong>of</strong> 0.08 (normal value: 0.00-0.90) and<br />

positive Cytomegalovirus DNA qualitative PCR. She underwent liver biopsy which revealed inflammation<br />

but no cellular necrosis and preserved architecture. She was discharged to clinic follow-up. One week<br />

later her liver function had improved to AST 43, ALT 42 and ALP 120. Her fever spontaneously resolved.<br />

Repeat titers <strong>of</strong> cytomegalovirus IgM and IgG after 2 weeks were 5.80 and 2.53 respectively.<br />

DISCUSSION: Cytomegalovirus infection in apparently immunocompetent hosts is traditionally<br />

regarded as a benign, self-limited illness. However, there have been several reports <strong>of</strong> severe<br />

cytomegalovirus infections in immunocompetent hosts. Severe cytomegalovirus hepatitis has been<br />

defined as a fivefold rise <strong>of</strong> ALT, jaundice or a degree <strong>of</strong> liver involvement requiring hospitalization.<br />

Cytomegalovirus should be tested in immunocompetent adults who present with fever and unexplained<br />

hepatitis. The role <strong>of</strong> antivirals in severe cytomegalovirus hepatitis in immunocompetent hosts remains<br />

unclear. Randomized controlled studies need to be carried out<br />

Bilateral empyema: A rare complication <strong>of</strong> Celiac Plexus Block.<br />

Pramod Pantangi, MD Second Author:Praveen Sampath, MD<br />

INTRODUCTION: Abdominal pain secondary to chronic pancreatitis is difficult to treat, with significant<br />

proportion <strong>of</strong> patients having ongoing pain in spite <strong>of</strong> being on large dose opioid analgesics. Celiac<br />

plexus block (CPB) was primarily developed to treat refractory pain, particularly in patients with small<br />

ductal involvent where endoscopic decompressive techniques <strong>of</strong> pancreatic duct are <strong>of</strong> low yield. We<br />

describe a case where a patient who underwent CPB, presented with bilateral empyema and<br />

mediastinal collection from an extension <strong>of</strong> retro gastric retroperitoneal collection, which occurred as a<br />

complication CPB.<br />

CASE PRESENTATION: A 40-year-old female with history <strong>of</strong> chronic pancreatitis secondary to<br />

gallstones, who had undergone a EUS guided CPB one month ago, presented to the ER with increasing<br />

abdominal pain and fever. Clinical examination was unremarkable. Labs revealed white count <strong>of</strong> 16K<br />

with normal pancreatic enzymes. CT <strong>of</strong> the abdomen showed a retro gastric retroperitoneal collection<br />

near GE junction measuring about 7cmX5cm.She was started on imipenem. Subsequently, she<br />

developed shortness <strong>of</strong> breath. Chest CT showed extension <strong>of</strong> the retrogastric collection into<br />

medistinum and bilateral pleural spaces. Bilateral chest tubes were placed. Blood cultures were negative<br />

and pleural fluid cultures grew Strep.milleri group. Her esophagogram did not show any ongoing leak.<br />

She was managed conservatively and discharged with 6 weeks <strong>of</strong> IV antibiotics. Patient was<br />

symptomatically much better and her white count normalized. Repeat CT scan after 6 weeks showed<br />

complete resolution <strong>of</strong> pleural, mediastinal and retroperitoneal collections.<br />

DISCUSSION: CPB involves injection <strong>of</strong> an anesthetic agent and steroid into the celiac plexus. EUS<br />

guided CPB recently gained popularity secondary to better access to the celiac plexus. Different metaanalysis<br />

report the complication rates at around 1.8-2%. Complications include post-procedural selflimiting<br />

pain, hypotension and retroperitoneal abscess. There are only few case reports <strong>of</strong> empyema as<br />

a complication <strong>of</strong> CPB. It can occur either as an extension from mediastinitis from perforation <strong>of</strong><br />

esophagus during procedure or as in our case, an extension from retroperitoneal abscess. Causative<br />

flora can be polymicrobial or mostly Strep.milleri group, which are commensals in the GI tract.<br />

Management generally includes IR guided drainage <strong>of</strong> the retroperitoneal abscess (if accessible), chest<br />

tubes for empyema and antibiotics for at least 4 weeks. Small mediastinal and retroperitoneal<br />

collections as in our case, resolve with drainage <strong>of</strong> empyema and IV antibiotics. Larger collections<br />

require open drainage. EUS guided drainage is not recommended to avoid introducing further infection<br />

and because <strong>of</strong> the risk <strong>of</strong> disseminating the infection into the peritoneal cavity.<br />

RENAL TUBULAR ACIDOSIS, A RARE COMPLICATION OF BARIATRIC SURGERY<br />

; Resmi Premji MD, Richa Aggarwal MD, Kameswari Lakshmi MD, Prasanta Basak MD, Stephen Jesmajian<br />

MD<br />

INTRODUCTION:Normal anion gap metabolic acidosis after bariatric surgery is <strong>of</strong>ten due to intestinal<br />

bicarbonate losses. Renal compensation in this setting occurs by acidification <strong>of</strong> urine resulting in a low<br />

urinary pH and negative urine anion gap. Here we report a patient who underwent bariatric surgery and<br />

had normal anion gap metabolic acidosis but found to have a high urinary pH and positive urine anion<br />

gap. We attribute these changes to type 1 renal tubular acidosis, a rare complication <strong>of</strong> jejunoileal<br />

bypass surgery.<br />

CASE PRESENTATION: A 39 year old female with history <strong>of</strong> multiple sclerosis and jejunoileal bypass<br />

surgery 10 years ago, was brought to the emergency room with complaints <strong>of</strong> shortness <strong>of</strong> breath and<br />

generalized weakness for one month. She had associated symptoms <strong>of</strong> nausea and vomiting for several<br />

days. On examination, she was hypotensive (100/70 mm Hg) and tachycardic (120-130 bpm). Laboratory<br />

data showed normal anion gap metabolic acidosis (Sodium: 147 mEq/L, Potassium: 3.0 mEq/L, Chloride:<br />

134 mEq/L and CO2: 4.4 mEq/L) and normal renal function (BUN: 3mg/dL, Creatinine: 0.6mg/dL).<br />

Arterial blood gas revealed pH: 7.16, PCO2: 18.9 mm <strong>of</strong> Hg, HCO3: 8.3 mEq/L and lactate: 2.6 mEq/L.<br />

Urine pH was 6.0, urine sodium: 54 mEq/L, potassium: 30 mEq/L, chloride: 81mEq/L and urine anion gap<br />

3.0. The high urinary pH and positive urine anion gap suggested the metabolic acidosis is due to renal<br />

tubular acidification defects rather than induced by her vomiting. Patient was placed on bicarbonate<br />

infusion, three ampoules <strong>of</strong> bicarbonate in D5W at 200 ml/hour for 2 days. Her hyperchloremia and<br />

metabolic acidosis improved and weakness resolved, with no further episodes <strong>of</strong> nausea or vomiting.<br />

DISCUSSION: The exact pathogenesis <strong>of</strong> distal RTA in bariatric surgery patients is not known. Some <strong>of</strong><br />

the proposed mechanisms are deposition <strong>of</strong> immune complexes in the tubules, and a causal association<br />

with hyperoxaluria. In these patients there is impaired acidification <strong>of</strong> urine, and urine ammonium fails<br />

to rise in the setting <strong>of</strong> acidosis. Ammonium is an unmeasured cation and a decrease in its excretion, as<br />

NH4Cl leads to low urine chloride concentration, and therefore a positive urine anion gap and high<br />

urinary pH. [Urine AG= Urine (Na+ K- Cl)]. Although bicarbonate replacement would provide temporary<br />

benefit in these patients, the ultimate treatment would be a revision <strong>of</strong> the surgery. With bariatric<br />

surgery becoming more commonplace, clinicians need to be aware <strong>of</strong> this potential late complication <strong>of</strong><br />

the procedure.<br />

Seronegative Longitudinally Extensive Transverse Myelitis (LETM) mimicking Multiple Sclerosis (MS)<br />

Ameer Z Rasheed, MD Wiswanath Vasudevan, MD Naveen Goyal, MD. Celinah Olalowo, MD.<br />

INTRODUCTION:Neuromyelitis optica (NMO) is a rare but severe, debilitating disease that<br />

predominantly features immunopathology in optic nerves and spinal cord sparing the brain white<br />

matter. NMO has a rare variant, Longitudinally Extensive Transverse Myelitis (LETM) which<br />

predominantly involves spine. We present a very rare case <strong>of</strong> LETM with brain white matter involvement<br />

similar to Multiple Sclerosis.<br />

CASE PRESENTATION: 59 y/o AA female presented with inability to walk, bilateral lower extremity<br />

weakness and numbness for 2 weeks. She reported milder form <strong>of</strong> similar symptoms in past when she<br />

was investigated with MRI brain was treated for MS. Physical examination revealed intact cranial nerves,<br />

markedly decreased strength, decreased sensation and hyper reflexes in lower extremities. Her initial<br />

labs were in normal limits. She was started on high dose <strong>of</strong> corticosteroids for possible MS. MRI brain<br />

revealed extensive diffuse grey-white matter lesions and swelling <strong>of</strong> the optic nerves suggestive <strong>of</strong> prior<br />

optic neuritis. CSF showed lymphocytic predominant high WBC count, high Glucose and normal protein.<br />

Cytology did not show any malignant cells. Bacterial antigens were not detected and cultures were<br />

negative. CSF IgG to albumin ratio, IgG index, IgG, IgM, and IgA levels were normal and there were no<br />

oligoclonal bands; myelin basic protein and IgG synthesis rate were high; VDRL and Lyme titers were<br />

negative. ESR and CRP were high but ANA, Anti DNA, SS-A, SS-B and Rheumatoid factor antibodies were<br />

negative. MRI C-spine showed increased T2-weighted signal from the C3 level to the T5 level, signal<br />

abnormality involved the central aspect <strong>of</strong> the spinal cord. MRI T-spine showed enhancing lesion within<br />

thoracic cord posterior to the T2 through T6 within the central aspect <strong>of</strong> the spinal cord. In light <strong>of</strong><br />

patient's poor response to IV steroid and lesions seen on MRI <strong>of</strong> the entire spine, a more likely diagnosis<br />

was LETM. She received plasmapheresis and showed a marked improvement in symptoms.<br />

DISCUSSION: Longitudinally Extensive Transverse Myelitis (LETM) is a rare form <strong>of</strong> NMO in which the<br />

spinal cord is predominantly affected. NMO (anti- Aquaporin-4 channel) antibodies are specific for this<br />

entity. We report a very rare case <strong>of</strong> seronegative form <strong>of</strong> LETM which initially presented with typical<br />

MS looking brain lesions, and report successful treatment with plasmapharesis.<br />

Conclusion: In older patients with relapsing neurological symptoms mimicking MS; Negative work-up for<br />

MS, infectious and autoimmune disorders should trigger diagnosis <strong>of</strong> NMO. Presence <strong>of</strong> contiguous<br />

hyperintense lesion on spinal cord imaging suggests LETM. Absence <strong>of</strong> NMOantibodies in presence <strong>of</strong><br />

clinical impression and radiological evidence doesn’t exclude LETM. These patients should be treated<br />

with plasmapharesis and not with high dose IV steroids.<br />

Sulfamethoxazole<br />

Jharendra P Rijal, MBBS Tiffany Pompa, MD, Venkat Raja Surya, MD, MPH, Ayesha S Siddiqui, MBBS,<br />

Tarek Abdallah, MD, Vijaya Raj Bhatt, MBBS<br />

CASE PRESENTATION: A 62-year-old woman presented to the emergency department with diffuse<br />

erythematous rashes over her body following the second dose <strong>of</strong> oral trimethoprim-sulfamethoxazole<br />

use prescribed for uncomplicated lower urinary tract infection. The lesion started as painful<br />

erythematous macules, turned into blisters followed by diffuse exfoliation <strong>of</strong> skin involving bilateral<br />

lower extremities, back, abdomen, and both forearms. Past medical history was significant for<br />

hypertension, dyslipidemia, coronary artery disease and coronary artery bypass graft. Her daily<br />

medications included simvastatin, clopidogrel, aspirin, lisinopril and metoprolol. Patient denied any<br />

known allergy. Physical examination was remarkable for multiples areas <strong>of</strong> erythema, blisters and<br />

extensive detachment <strong>of</strong> skin involving 45 % body surface area. Face and oral cavities were spared.<br />

Nikolsky sign was positive. She was admitted to the burn unit, and managed with intravenous fluid and<br />

extensive wound care. A punch biopsy <strong>of</strong> skin revealed full thickness epidermal necrosis with<br />

subepidermal blister formation and the presence <strong>of</strong> perivesicular lymphocytes as well as dermal<br />

inflammation. This was consistent with toxic epidermal necrolysis (TEN). Hospital course was<br />

complicated by cellulitis <strong>of</strong> right leg due to Pseudomonas aeruginosa and central venous catheterrelated<br />

sepsis due to Acinetobacter baumanni sensitive only to tobramycin, acute respiratory distress<br />

syndrome, acute kidney injury, and diastolic congestive heart failure. Intensive medical management<br />

including aggressive antibiotic use and meticulous wound care with frequent wound debridement led to<br />

the resolution <strong>of</strong> these complications. The patient had remarkable regeneration <strong>of</strong> skin over subsequent<br />

few weeks and she was discharged home after one month.<br />

DISCUSSION: TEN is a rare adverse drug reaction with an incidence between 0.4 to 1.3 cases per million<br />

each year but with a mortality rate as high as 40 %. It is thought to result from an autoimmune reaction<br />

in skin leading to necrosis and separation <strong>of</strong> the epidermis. Denuded skin and damaged mucosa<br />

predispose to infection which can lead to sepsis and respiratory distress, as in our case. TEN is<br />

diagnosed clinically with prodrome <strong>of</strong> fever, malaise, and multitude <strong>of</strong> nonspecific symptoms followed<br />

by maculopapular painful erythema, blisters and sloughing <strong>of</strong> epidermis and mucous membrane<br />

involving greater than 30 % body surface. The diagnosis is further supported by the history <strong>of</strong> drug<br />

exposure and the histological findings as described above. Trimethoprim-Sulfamethoxazole, an<br />

extremely commonly used antimicrobial, has been rarely reported to cause TEN. Given the lifethreatening<br />

nature <strong>of</strong> the disease, both physicians as well as patients should be aware <strong>of</strong> this rare<br />

complication. Although rapid onset <strong>of</strong> dermatologic changes without prodromal symptoms over a day is<br />

an extremely unusual presentation, as illustrated by this case, it’s a distinct possibility. Early recognition<br />

<strong>of</strong> signs and symptoms <strong>of</strong> TEN and early drug discontinuation is essential and decreases mortality.<br />

Tadros, MD, Srujitha Murukutla, MBBS, Jeffrey Rothman, MD, FACP, FACE<br />

INTRODUCTION:When patients present with episodic paralysis it is important to identify the<br />

underlying cause. We report a case <strong>of</strong> periodic paralysis in a young man with recurrent episodes and a<br />

delay in diagnosis.<br />

CASE PRESENTATION: A 20-year-old Chinese man presented to the emergency department with a 3hour<br />

history <strong>of</strong> progressive weakness <strong>of</strong> all extremities that began on awakening in the morning. The<br />

patient gave a history <strong>of</strong> similar episodes <strong>of</strong> muscle weakness occurring after intake <strong>of</strong> carbohydrate-rich<br />

food. There was a history <strong>of</strong> periodic muscle weakness in his paternal uncle and grandfather. The<br />

patient’s prior paralytic attacks were therefore attributed to familial hypokalemic periodic paralysis<br />

(HPP) and he was treated with oral potassium supplementation. In addition to generalized muscle<br />

weakness, physical examination revealed tremor <strong>of</strong> outstretched hands and tachycardia. The thyroid<br />

was not palpably enlarged. Laboratory tests included serum sodium <strong>of</strong> 138 mmol/l, potassium <strong>of</strong> 3.1<br />

mmol/l, chloride <strong>of</strong> 103 mmol/l, bicarbonate <strong>of</strong> 30 mmol/l, calcium <strong>of</strong> 9.0 mg/dl, magnesium <strong>of</strong> 2.3<br />

mg/dl, glucose <strong>of</strong> 104 mg/dl, creatine kinase <strong>of</strong> 186 IU/L, renin <strong>of</strong> 8.43 ng/ml, and aldosterone <strong>of</strong> 3<br />

ng/dl. Serum TSH concentration was 0.06 µIU/ml, with free T4 concentration <strong>of</strong> 2.6 ng/dl. Complete<br />

blood count, renal and liver function tests were all within normal limits. The patient improved after<br />

replacement <strong>of</strong> potassium. Further questioning revealed a history <strong>of</strong> tremors, sweating, tremulousness<br />

and 5-pound weight loss over the past 5 weeks as well as a history <strong>of</strong> hyperthyroidism in the patient’s<br />

maternal grandmother. A diagnosis <strong>of</strong> thyrotoxic periodic paralysis (TPP) was established and the<br />

patient was started on oral propranolol and methimazole. During the following 10 days, patient had two<br />

further episodes <strong>of</strong> paralysis that responded to potassium supplementation. Further evaluation included<br />

a 24-hour radioactive iodine uptake <strong>of</strong> 77% with diffuse thyroidal uptake on imaging consistent with<br />

Graves’ disease. The patient was then treated with a therapeutic dose <strong>of</strong> 131 Iodine. Five months after<br />

131I therapy, the patient is doing well.<br />

DISCUSSION: This case illustrates the relative lack <strong>of</strong> awareness <strong>of</strong> TPP among physicians leading to a<br />

delay in diagnosis, which is heightened because TPP is <strong>of</strong>ten the first manifestation <strong>of</strong> thyrotoxicosis.<br />

Thyroid function tests should be performed in all cases <strong>of</strong> periodic paralysis. This has important<br />

therapeutic implications: because the pathogenesis <strong>of</strong> the disorder involves redistribution <strong>of</strong> potassium<br />

and not total body depletion, TPP requires cautious potassium supplementation since rebound<br />

hyperkalemia may occur with recovery and aggressive potassium use. Propranolol can be used to<br />

reverse muscle weakness and symptoms generally resolve completely with correction <strong>of</strong> underlying<br />

thyrotoxicosis.<br />

Late Presentation Infective Endocarditis in a Patient with CardioSEAL PFO Closure Device<br />

School <strong>of</strong> Medicine, NY<br />

INTRODUCTION: The presence <strong>of</strong> a patent foramen ovale (PFO) is prevalent within the population and<br />

has been associated with increased risk for cryptogenic stroke. PFO closure devices (PFOCD) have been<br />

increasingly used as an alternative to antithrombotic therapy for prevention <strong>of</strong> recurrent<br />

thromboembolism. Procedural complications include malposition, embolization, fractures, hematoma,<br />

residual shunting, and thrombosis. Infections are very rare and occur early postimplantation.<br />

Endocarditis occurring more than 6 months postimplantation has never been reported. We present the<br />

case <strong>of</strong> an infected CardioSEAL PFOCD occurring 5 years post-procedure.<br />

CASE PRESENTATION: 59 year old male who presented to the hospital with transient left-sided<br />

weakness 5 years postimplantation <strong>of</strong> a PFOCD. As part <strong>of</strong> his work-up, a transthoracic echocardiogram<br />

(TTE) was performed which showed a mobile echodensity within the left atrium (LA). The<br />

transesophageal echocardiogram (TEE) confirmed the TTE findings and revealed a large 2.2x0.6cm<br />

mobile polypoid echodensity on the LA aspect <strong>of</strong> the PFOCD highly suggestive <strong>of</strong> thrombus or<br />

vegetation. The patient reported no health problems (including fever), or any other invasive procedures<br />

that would predispose him to developing endocarditis prior to presentation. He denied i.v. drug abuse.<br />

In the absence <strong>of</strong> any signs <strong>of</strong> infection or fever a presumptive diagnosis <strong>of</strong> device thrombosis was made<br />

and the patient was started on i.v. anticoagulation. However, given the size <strong>of</strong> the mass and potential<br />

embolic risk, the decision was subsequently made to remove the mass surgically. Microbiological<br />

analysis revealed the presence <strong>of</strong> MSSA and micrococcus species within the mass consistent with<br />

vegetation. The patient had a stable post-operative course and was treated with six weeks <strong>of</strong> i.v.<br />

antibiotics.<br />

DISCUSSION: Few cases <strong>of</strong> infective endocarditis related to PFOCD have been reported in the<br />

literature. All previous reports have involved infections occurring within 6 months <strong>of</strong> implantation,<br />

before complete device endothelialization, as confirmed at the time <strong>of</strong> surgical removal. Uniquely, ours<br />

is the first case <strong>of</strong> infection manifesting beyond this time period. During the first 3-6 months<br />

postimplantation patients are at highest risk for complications, as the devices are not completely<br />

endothelialized. Current guidelines recommend antibiotic and antiplatelet prophylaxis during this time<br />

interval.<br />

Our case highlights the importance <strong>of</strong> considering the presence <strong>of</strong> vegetation (or thrombus) associated<br />

with a PFOCD in the differential diagnosis <strong>of</strong> a patient presenting with embolic phenomena or an<br />

endocarditis-like picture even beyond the expected time frame, as prompt diagnosis and treatment are<br />

crucial for preventing further catastrophic events and improving clinical outcome. As illustrated,<br />

echocardiography plays a central diagnostic role in the management <strong>of</strong> these patients and should be<br />

performed without delay.<br />

INTRODUCTION: “This is a disease that begins where other diseases end, with death.” -NEJM<br />

1979;301(23)<br />

Liver abscess secondary to Clostridium perfringens is a rare phenomenon resulting in septicemia,<br />

massive intravascular hemolysis and end organ damage. Due to its lack <strong>of</strong> recognition most cases thus<br />

far have been fatal.<br />

CASE PRESENTATION: A 65-year- old female with uncontrolled diabetes returns from a 2 month trip to<br />

Jordan. She was doing well until the day prior to admission, when she suddenly developed high grade<br />

fevers, chills, nausea and generalized weakness. The day <strong>of</strong> admission she developed right sided<br />

shoulder and right upper quadrant abdominal pain. In the ER, her temperature was 39.1 degrees Celsius,<br />

but otherwise was hemodynamically stable. She was diaphoretic and in significant distress. Her labs<br />

were significant for elevated liver function tests, anemia, significant leukocytosis and acute kidney<br />

injury. Imaging showed slightly thickened gallbladder wall and mildly dilated common bile ducts without<br />

evidence <strong>of</strong> cholelithiasis, pericholecystic fluid or sonographic evidence <strong>of</strong> Murphy’s sign; however a<br />

gas-containing hepatic lesion in the posterior aspect <strong>of</strong> the right hepatic lobe was noted on the CT scan.<br />

Blood cultures drawn on admission formed gas, and grew gram positive rods, suggestive <strong>of</strong> clostridium<br />

versus bacillius. Given these findings, the patient was immediately started on broad spectrum<br />

antibiotics: Metronidazole was started to cover clostridium, its toxins and other anaerobes; Ampicillin<br />

was started to cover Enterococcus and Listeria as well as other gram positive organisms; Ceftriaxone<br />

was started to give broader gram negative coverage for the suspected intra-abdominal pathology. On<br />

day two <strong>of</strong> her admission, the patients fever had subsided, and she felt subjectively better. However her<br />

hemoglobin dropped further. Work-up indicated worsening hemolysis. On Gram’s staining, the organism<br />

showed a double zone <strong>of</strong> hemolysis which helped further identify the organism as Clostridium<br />

perfringens. Thus, she underwent an emergent interventional radiology-guided drain placement <strong>of</strong> her<br />

hepatic lesion. Ten milliliters <strong>of</strong> pus was drained. She was also transfused with 2 units <strong>of</strong> blood. During<br />

the subsequent days, her hemoglobin stabilized, acute kidney injury resolved and patients overall<br />

condition improved significantly.<br />

DISCUSSION: Thus far, approximately 42 cases <strong>of</strong> Clostridium perfringens septicemia have been<br />

reported in literature. Of these 11 cases were due to liver abscess. Most cases were complicated by<br />

severe hemolysis and multiorgan failure and many had fatal endings; especially when invasive<br />

procedure to remove the focus <strong>of</strong> infection was not undertaken. This case demonstrates that with early<br />

identification/recognition <strong>of</strong> this disease process and early intervention with drainage and antibiotics,<br />

such complications can be eliminated.<br />

used to reverse the platelet dysfunction associated with uremia, cirrhosis, and anti-platelet agents such<br />

as aspirin and clopidogrel.<br />

CASE PRESENTATION: A 67-year-old man with a history <strong>of</strong> coronary artery disease was admitted to the<br />

hospital after sustaining a traumatic injury to the skull. Three years prior, the patient underwent cardiac<br />

catheterization which revealed severe stenosis <strong>of</strong> the proximal left anterior descending (LAD)<br />

artery. This lesion was revascularized with angioplasty and placement <strong>of</strong> a drug-eluting stent. He was<br />

subsequently treated with aspirin and clopidogrel. On the morning <strong>of</strong> admission, an air conditioner<br />

spontaneously fell from a window, landed on an awning, and subsequently struck the patient on the<br />

right side <strong>of</strong> the head as he was walking.<br />

He was brought to the emergency room with a seven centimeter laceration on the right scalp. A noncontrast<br />

CT scan <strong>of</strong> the head demonstrated a large subgaleal hematoma without intracranial<br />

bleeding. Due to persistent bleeding, DDAVP was administered intravenously thirty minutes after<br />

presentation. Five hours later, the patient complained <strong>of</strong> crushing chest pain. A 12-lead<br />

electrocardiogram demonstrated 2 mm ST-segment elevations in the precordial leads with reciprocal<br />

depressions in the inferior leads.<br />

Emergent cardiac catheterization demonstrated total occlusion <strong>of</strong> the proximal LAD stent with TIMI 0<br />

flow. Bivalirudin was initiated as per protocol. Atherectomy was attempted, but thrombus was not<br />

aspirated. A Promus 3.0 x 18 mm stent was placed inside the original stent with restoration <strong>of</strong> TIMI 3<br />

flow. During the catheterization, the patient became progressively hypoxic and hypotensive requiring<br />

intubation, dopamine drip, and placement <strong>of</strong> an intra-aortic balloon pump (IABP).<br />

The patient’s hospitalization was complicated by prolonged shock requiring inotropes and vasopressors.<br />

The IABP was removed on day four. Dopamine was titrated <strong>of</strong>f by day seven, and the patient<br />

was successfully extubated on day 13. A transthoracic echocardiogram demonstrated a left ventricular<br />

ejection fraction <strong>of</strong> 30% with severe anterior and apical hypokinesis. The patient was discharged to<br />

inpatient rehabilitation on day 21.<br />

DISCUSSION: This is the first reported case <strong>of</strong> an ST-elevation MI due to in-stent thrombosis occurring<br />

after DDAVP administration. Though DDAVP is safe and efficacious in treating several types <strong>of</strong><br />

coagulopathies, this case illustrates its potential pro-thrombotic effects. Therefore, DDAVP should be<br />

used with caution in patients with known coronary artery disease and coronary stents.<br />

Pneumocephalus after attempted Epidural Anesthesia<br />

Tulsi Sharma, MBBS Pankaj Mehta MD<br />

INTRODUCTION:Epidural anesthesia and analgesia are being increasingly used as they facilitate an<br />

earlier recovery and reduce the incidence <strong>of</strong> postoperative thromboembolic, pulmonary, and<br />

gastrointestinal complications after major surgery.<br />

CASE PRESENTATION: We present the case <strong>of</strong> a 66-year-old male with a history <strong>of</strong> perforated<br />

diverticulitis and prior Hartmann pouch procedure, admitted for an elective colostomy closure. Epidural<br />

catheter placement was initially attempted but was unsuccessful and the surgery performed under<br />

general anesthesia. He underwent a colonoscopy and successful reversal <strong>of</strong> his colostomy. The patient<br />

was successfully extubated and transferred to the postoperative recovery unit. His vitals were stable and<br />

he was responding to commands. About 10 minutes after transfer the patient suddenly became<br />

unconscious, hypoxic, with a strong neutral gaze nystagmus and his systolic blood pressure was over<br />

200. He was reintubated and an emergent CT-head was done with concerns for a stroke. CT however<br />

showed evidence <strong>of</strong> air in the ventricles. Where did the air come from? He had developed a<br />

pneumocephalus from the attempted epidural anesthesia. He was transferred to the ICU and started on<br />

100%FiO2. His sensorium and motor functions improved over the next few hours. Brain imaging over<br />

the next 2 days revealed decreasing intraventricular air. He recovered without any neurological deficits<br />

and was successfully extubated and transferred to the surgical service for his postoperative<br />

management.<br />

DISCUSSION: Pneumocephalus is a well-known complication <strong>of</strong> spinal anesthesia, but it is extremely<br />

rare after an epidural puncture. We present this case to highlight the importance <strong>of</strong> a clinical suspicion<br />

<strong>of</strong> this complication from epidural procedures. The differential <strong>of</strong> an acute onset headache after an<br />

epidural puncture could be a postdural puncture headache(PDPH), a subarachnoid hemorrhage(SAH), or<br />

a pneumocephalus. Patients present with signs <strong>of</strong> frank neurological injury as in our patient, but some<br />

may present with only subtle signs or with just a persistent severe headache. An important clue may be<br />

that these headaches are typically not position dependent in contrast to the PDPH.<br />

The postulated mechanism <strong>of</strong> air entry is either by injection during procedure when air is used in the<br />

loss <strong>of</strong> resistance technique or by the pressure differential created between the spine and an<br />

unoccluded needle. The potential for a pneumocephalus can be reduced by using normal saline during<br />

the loss <strong>of</strong> resistance technique as well as limiting the time the stylet is withdrawn from the needle. Less<br />

than 2ml <strong>of</strong> subarachnoid air can cause headache but the correlation between the amount <strong>of</strong><br />

intracranial air and headache symptoms is less than perfect.<br />

The use <strong>of</strong> a high oxygen concentration can hasten absorption <strong>of</strong> intracranial air and reduce chances <strong>of</strong><br />

neurological injury. Prognosis is usually good and an early diagnosis may prevent unnecessary tests and<br />

interventions.<br />

An Unusual Cause <strong>of</strong> Multiple Pulmonary Nodules<br />

Tulsi Sharma, MBBS Pankaj Mehta, MD Roberto Izquierdo, MD<br />

INTRODUCTION: Many diseases can present with a miliary lung pattern, especially in<br />

immunocompromised patients. What can be the differential in a young asymptomatic and<br />

immunocompetent individual?<br />

CASE PRESENTATION: We present the case <strong>of</strong> a 21-year-old lady who had been in her usual state <strong>of</strong><br />

health until October 2008 when she had a motor vehicle accident. A CT-thorax obtained at an outside<br />

facility did not reveal any traumatic injury, however, it revealed a diffuse reticulonodular pulmonary<br />

process. Subsequent sputum for AFB and PPD were negative and she was asymptomatic. She did not<br />

return for her follow-up appointments and returned to her PCP in November 2009 for a regular yearly<br />

evaluation. Repeat CT-thorax revealed a stable nodular pattern. She was then referred to Upstate<br />

Medical University with possible diagnosis <strong>of</strong> sarcoidosis. At the time <strong>of</strong> referral in early 2010 she still<br />

denied any constitutional symptoms. Clinical exam was normal. Repeat CT-thorax revealed persistence<br />

<strong>of</strong> the miliary pattern. Blood work, ACE-level and PPD were negative. What would cause these numerous<br />

nodules which have been stable for 2 years and without any clinical manifestations?<br />

After discussion <strong>of</strong> the risks and benefits <strong>of</strong> bronchoscopy, the patient agreed to the procedure.<br />

Bronchoscopy with transbronchial biopsy revealed metastatic well-differentiated papillary thyroid<br />

carcinoma (PTC)! Sonography <strong>of</strong> the thyroid revealed a small solid nodule in the left thyroid lobe with<br />

internal and peripheral vascular flow on Doppler interrogation <strong>of</strong> the nodule. The patient underwent a<br />

near-total thyroidectomy and a limited central compartment neck dissection. The patient has since<br />

undergone radioactive iodine therapy and is on thyroid hormone replacement therapy. Her follow up<br />

hypothyroid I131 whole body scan showed a significant decrease in uptake in the lungs.<br />

DISCUSSION: Papillary thyroid carcinoma is the most common malignant thyroid cancer, and accounts<br />

for approximately 80% <strong>of</strong> thyroid cancers. Involvement <strong>of</strong> regional lymph nodes is seen in 20-80% <strong>of</strong><br />

patients with PTC at the time <strong>of</strong> initial surgery. Diffuse lung metastatic disease from an occult thyroid<br />

cancer is however extremely rare. Diagnosis based on a transbronchial biopsy in an asymptomatic<br />

patient with incidental nodules makes it even more intriguing.<br />

The growth rate <strong>of</strong> pulmonary nodules is <strong>of</strong>ten used to help differentiate benign from malignant disease.<br />

Pulmonary nodules that exhibit lack <strong>of</strong> growth for more than two years are generally considered benign.<br />

However, nodular lung metastases from papillary thyroid carcinoma are an exception and may<br />

demonstrate lack <strong>of</strong> significant growth over years. The cause <strong>of</strong> this arrest <strong>of</strong> metastatic growth in PTC is<br />

unknown.<br />

PTC has the best prognosis <strong>of</strong> the thyroid malignancies with a 90% 10-year survival. Even in the presence<br />

<strong>of</strong> metastatic spread, survival periods may exceed 20 years, especially in the young. Hopefully the<br />

accident was actually a blessing in disguise!<br />

Not All That Is White Is Candida: A Case Of Recurrent Aspergillus Esophagitis In An Hiv/Aids Patient.<br />

Yahuza Siba, MD<br />

INTRODUCTION: The differential diagnosis for odynophagia/dysphagia in an AIDS patient is broad, thus<br />

tissue diagnosis prior to treatment is very important to avoid misdiagnosis.<br />

CASE PRESENTATION: A 23 year old Hispanic woman (homosexual orientation) with perinatally<br />

acquired HIV, non compliant with antiretroviral (ARV) therapy with recent CD4 count <strong>of</strong> 11 and viral load<br />

<strong>of</strong> 187, 000 presented with severe odynophagia. She has history <strong>of</strong> opportunistic infections including<br />

oral candidiasis, pneumocystic jeroveci pneumonia and anal warts. She was referred from the infectious<br />

disease clinic for parenteral therapy with casp<strong>of</strong>ungin for oral candidiasis as patient did not get<br />

symptomtic relief with nystatin and prior therapy with fluconazole for oral candidiasis was discontinued<br />

because <strong>of</strong> erythema multiforme.<br />

Vitals at presentation were: Temperature 99.4F, Pulse 111, BP 119/75 her body mass index was 23.9.<br />

Physical exam was notable for florid oral thrush. The remainder <strong>of</strong> the exam was unremarkable. She<br />

was admitted with the impression <strong>of</strong> oral/esophageal candidiasis and was started on casp<strong>of</strong>ungin. She<br />

underwent EGD which showed copious whitish patch involving the proximal and mid-esophagus<br />

consistent with candida. Preliminary histology showed acute necrotizing candidiasis, pending special<br />

stains. Aspergillus (probably fumigatus) was the final diagnosis after GMS stain. Patient’s antifungal was<br />

switched to Amphoterin B (lipid form), her dysphagia resolved and was discharged for outpatient follow<br />

up. A second EGD done one month later showed whitish lesions had cleared with negative biopsy<br />

results. Four months later she again presented with odynophagia and repeat EGD with histology<br />

histology showed Aspergillus spp. Meanwhile patient has refused re-treatment and her follow up visit is<br />

pending.<br />

DISCUSSION: Aspergillus spp. are ubiquitous in nature and grow in a variety <strong>of</strong> conditions. The septate<br />

hyphae are characteristically 3-6um in diameter and branch at 45% angles. The most critical<br />

determinant for inhalation <strong>of</strong> Aspergillus conidia progressing to invasive disease is the status <strong>of</strong> the host<br />

defenses. Risk factors for invasive aspergillosis include neutropenia, aplastic anemia, high dose<br />

corticosteroids, advanced HIV/AIDS, poorly controlled diabetes mellitus, post chemotherapy and after<br />

bone marrow transplantation.<br />

Our patient had an an advanced AIDS with very low CD4 count and high viral load. Aspergillus<br />

esophagitis is one <strong>of</strong> the uncommon gastrointestinal manifestations <strong>of</strong> HIV/AIDS, our patient had what<br />

both clinically and endoscopically appeared to be candida and initial histopathology report was also<br />

reported as candida, however after special fungal staining it turned out to be Aspergillus which<br />

ultimately changed therapy. This case demonstrates the importance <strong>of</strong> endoscopic biopsy in<br />

immunocompromised patients presenting with dysphagia.<br />

RSV Infection-Induced ARDS in a Young Immuncompetent Woman<br />

Hemant Sindhu<br />

INTRODUCTION:Respiratory syncytial virus (RSV) is the most important cause <strong>of</strong> lower respiratory tract<br />

infections in young children. Despite being primarily known as a pediatric pathogen, RSV is now<br />

recognized as a significant problem in adult populations as well. Most illnesses are mild in adults, but<br />

significant morbidity and mortality can develop. We present the case <strong>of</strong> an adult female with RSV<br />

infection-induced adult respiratory distress syndrome.<br />

CASE PRESENTATION: A 41 y.o. female with past medical history significant for breast cancer was<br />

admitted with a five day history <strong>of</strong> progressive shortness <strong>of</strong> breath, non-productive cough, chest pain,<br />

fever and chills. The patient was a teacher’s aide at an elementary school and had been evaluated in the<br />

emergency department two days prior to admission with similar symptoms and discharged on<br />

azithromycin. Less than 24 hours after admission the patient developed acute respiratory failure<br />

requiring intubation and was transferred to the medical intensive care unit. Vitals on admission were<br />

remarkable for a temperature <strong>of</strong> 104.7°F and HR <strong>of</strong> 115 bpm. The physical exam was unremarkable<br />

except for sinus tachycardia. The laboratory analysis showed a leukocyte count <strong>of</strong> 6700/mm3, with 91%<br />

neutrophils, 7% bands, and 7% lymphocytes. Sputum gram staining revealed no bacterial or fungal<br />

pathogens. The initial chest radiograph (CXR) was clear with no evidence <strong>of</strong> acute disease. The CXR post<br />

intubation revealed diffuse bilateral alveolar infiltrates consistent with adult respiratory distress<br />

syndrome (ARDS). Urine antigen for legionella, particle agglutination test for the antibody for<br />

Mycoplasma pneumonia and nasopharyngeal swab for influenza were all negative. The patient<br />

underwent fiberoptic bronchoscopy and staining for bacteria, fungi, tuberculosis, as well as sputum and<br />

bronchoalveolar lavage liquid cultures all came back negative as well. However EIA for the RSV antigen<br />

in BAL liquid was intensely positive. Prior to the diagnosis <strong>of</strong> RSV, this patient had been treated with<br />

broad spectrum antibiotics but no improvement was observed clinically since the patient was still<br />

requiring mechanical ventilation and had persistent lung infiltrates on CXR. Thus, the administration <strong>of</strong><br />

inhaled ribavirin was considered, however before the medication could be given to the patient, she<br />

expired.<br />

DISCUSSION: The overall mortality <strong>of</strong> RSV infection-induced ARDS in previously healthy adults is 40%-<br />

60%. Diagnosis <strong>of</strong> RSV infection in adults is difficult because viral culture and antigen detection are<br />

insensitive tests due to low viral shedding. The treatment guidelines currently in existence for RSV in<br />

adults continue to be limited. Ribavirin is the only anti-viral agent approved for the treatment <strong>of</strong> RSV in<br />

the pediatric population. A few case reports have been published in which adult patients have been<br />

successfully treated with inhaled ribavirin. The role <strong>of</strong> inhaled ribavirin in adults is controversial, but it<br />

might have a therapeutic potential for severe RSV infection-induced ARDS in adults.<br />

A Case Of Miller Fisher Syndrome With Unusual Features: Brisk Tendon Reflexes And Facial Palsy<br />

Yuzhu Tang, MD, Second author: Khadija A. Mamsa, MD, Asok K. Lahiri*, MD, Zev Carrey, MD, Richard L.<br />

Petrillo, MD, Dariush Alaie, MD. Department <strong>of</strong> Medicine and Neurology*<br />

INTRODUCTION:Miller-Fisher syndrome (MFS), a variant <strong>of</strong> Guillain-Barre syndrome, which was<br />

described by Dr. Charles Miller Fisher, consists <strong>of</strong> the triad <strong>of</strong> ophthalmoplegia, areflexia, and ataxia in<br />

its classical form. Here we report a case <strong>of</strong> MFS which showed in addition to classical features,<br />

association <strong>of</strong> facial palsy and exaggerated reflexes, both <strong>of</strong> which are very rare in this condition.<br />

CASE PRESENTATION: A 64-year-old male presented with one day history <strong>of</strong> headache, double vision<br />

and wobbly gait. He had mild diarrhea and bronchitis 10 days ago for which he took doxycycline. He<br />

gave no history <strong>of</strong> disturbance <strong>of</strong> consciousness. Physical examination was normal except for left 6th<br />

cranial palsy and ataxia <strong>of</strong> gait. Pupils were equal and reactive to light. Patient managed to walk a few<br />

steps with unsteady gait.<br />

On following day, there was worsening <strong>of</strong> his condition. His vision was no longer double, rather blurred.<br />

He was unable to walk due to ataxia. On examination, both eyes were fixed in forward gaze positions<br />

with no ocular movement. Pupils were equal, but reaction to light was sluggish compared to previous<br />

day. Deep tendon reflexes were brisk. Over the next few days, he developed right facial muscle<br />

weakness, and deep tendom reflexes remained brisk. Ophthalmological consultant confirmed external<br />

and internal ophthalmoplegia. CT and MRI head showed no focal structural brain lesion, only<br />

periventricular microvascular ischemia. Laboratory findings showed normal glucose level, HbA1c 6.2%,<br />

negative RPR, normal lyme titer. Tensilon test was normal. CSF analysis protein was 39.44 mg/dl,<br />

Glucose 64 mg/dl, Cells 0, and negative culture.<br />

Diagnosis <strong>of</strong> MFS was suspected on clinical basis and subsequently confirmed by elevated serum antiganglioside-GQ1b<br />

level 43.<br />

The patient was treated with IVIG for 5 days. He showed mild improvement in headache and facial palsy,<br />

and could walk unsteadily prior to discharge to short term rehabilitation center. Total ophthalmoplegia<br />

persisted.<br />

DISCUSSION: Since MFS is a rare condition, common etiologies <strong>of</strong> acute onset <strong>of</strong> ophthalmoplegia and<br />

ataxia, such as brainstem stroke, infection, diabetic cranial neuropathy, Wernicke’s encelopathy and<br />

ocular myasthenia etc should be ruled out before the diagnosis <strong>of</strong> MFS. Despite the brisk reflexes,<br />

Bickerstaff brainstem encephalitis is unlikely in this case because <strong>of</strong> the normal CSF study and no<br />

disturbance <strong>of</strong> consciousness.<br />

Ophthalmoplegia is the most prevalent symptom in MFS which is closely correlated with anti-GQ1b IgG<br />

antibody, whereas facial palsy is only seen in about 22% <strong>of</strong> patients. Brisk tendon reflexes are seldom<br />

seen in MFS.<br />

Flatbush Diabetes: Freedom from Needles<br />

Pallawi Torka, MD Co-author: Debra Buchan, MD<br />

INTRODUCTION: Flatbush Diabetes is atypical, ketosis prone diabetes mellitus (DM) that presents with<br />

ketoacidosis. However, in contrast to type 1 DM, patients with Flatbush diabetes undergo spontaneous<br />

remission and maintain long-term insulin independence. This clinical vignette highlights the evolution<br />

and clinical aspects <strong>of</strong> Flatbush diabetes.<br />

CASE PRESENTATION: A 45 year old previously healthy African lady, originally from Tanzania,<br />

presented in diabetic ketoacidosis (DKA). She had no prior personal or family history <strong>of</strong> diabetes. Her<br />

BMI was 26 kg/m 2 . DKA was corrected and the patient was discharged on insulin. However within a<br />

month, her insulin requirements dropped drastically and she started becoming hypoglycemic. Insulin<br />

was stopped. She was able to control her sugars through diet; HbA1C was 6.2% three months later. The<br />

patient presented again eight months after initial symptoms with fatigue, weight loss and vaginal<br />

candidiasis. This time HbA1C was 9.2%. Fingerstick glucose was 378 mg/dl; however, anion gap was<br />

normal and there were no ketones in the blood or urine. She was restarted on insulin. Test results for<br />

anti glutamic acid decarboxylase and anti islet cell antibodies were negative; metformin was introduced<br />

in addition to insulin. Her insulin requirements have decreased since; however, it remains to be seen if<br />

she will be able to come <strong>of</strong>f insulin.<br />

DISCUSSION: Flatbush or Ketosis prone Type 2 diabetes was initially described in African <strong>American</strong>s but<br />

subsequently, it has been reported in other ethnicities too, especially South Asians. The mean age <strong>of</strong><br />

presentation is 40 years, with 2- to 3-fold higher preponderance in men. The prevalence <strong>of</strong> obesity is<br />

high among these patients and more than 80% have a family history <strong>of</strong> Type 2 DM. Typically, these<br />

patients present with unprovoked DKA in association with polyuria, polydipsia, and weight loss for less<br />

than 6 weeks. Although most patients undergo spontaneous remission requiring discontinuation <strong>of</strong><br />

insulin therapy within a few weeks, an estimated 60% to 70% <strong>of</strong> patients relapse within two years and<br />

require either oral hypoglycemic agents or insulin. <strong>Physicians</strong> need to be aware <strong>of</strong> this unusual form <strong>of</strong><br />

DM and be able to differentiate it from either slowly progressive Type 1 DM or the “honeymoon phase”<br />

<strong>of</strong> Type 1 DM; the differences between the two are summarized in the table below.<br />

Delayed Epiphyseal Closure in a Patient with Sickle Cell Anemia Complicated by Primary<br />

Hypogonadism<br />

Nay Min Tun, MD Second Authors: Linus Yoe, MD; Kathy Khaing, MD; Ma Sandar, MD; Aye Min Soe, MD<br />

INTRODUCTION:Hemoglobin S is most prevalent in tropical Africa. Sickle cell trait has a frequency <strong>of</strong><br />

approximately 8 percent in African-<strong>American</strong> populations. The expected prevalence <strong>of</strong> sickle cell<br />

anemia in the United States is 1 in 625 persons at birth. Impairment <strong>of</strong> skeletal and sexual maturation in<br />

early adolescence in patients with sickle cell anemia has been recognized. Plausible mechanisms include<br />

hypopituitarism resulting from intravascular thrombosis and pituitary infarction, reduced<br />

responsiveness <strong>of</strong> the testes to pituitary LH and FSH, and zinc deficiency.<br />

CASE PRESENTATION: 21-year-old African <strong>American</strong> male presented with low back, chest and bilateral<br />

knee pain. His past medical history was significant for sickle cell anemia with 4-5 pain crises a year and<br />

laparoscopic cholecystectomy. He had strong family history <strong>of</strong> sickle cell anemia and trait. Physical<br />

examination disclosed eunuchoidal skeletal proportions with a height <strong>of</strong> six feet and six inches and<br />

underdevelopment <strong>of</strong> secondary sexual characteristics. His pain symptoms improved with hydration and<br />

analgesia although the right knee pain persisted. X-ray <strong>of</strong> the right knee joint showed moderate<br />

suprapatellar joint effusion, 1.2 x 0.5 cm ovoid radiolucency in the femoral intercondylar notch and nonclosure<br />

<strong>of</strong> the epiphyseal plate. Magnetic resonance imaging revealed acute distal femoral metaphyseal<br />

marrow infarct, non-closure <strong>of</strong> epiphysis with a small region <strong>of</strong> non-specific edema, and moderate joint<br />

effusion. Bone age assessment with X-ray <strong>of</strong> the hand showed a physiological bone age <strong>of</strong> 18 years and 0<br />

months (+/- 10 months). Hormonal workup was done to find out the cause for delayed skeletal growth.<br />

He was found to have low total and free testosterone levels with high follicular stimulating hormone<br />

(FSH) and luteinizing hormone (LH) levels. Prolactin level was mildly elevated that might be attributable<br />

to hydromorphone that was given for pain. Thyroid function and Cosyntropin stimulation tests were<br />

normal so were random cortisol, growth hormone and insulin-like growth factor 1 levels. He was<br />

diagnosed to have primary hypogonadism, and testosterone therapy and multivitamin supplementation<br />

were initiated with subsequent improvement in libido and virilization.<br />

DISCUSSION: Delayed epiphyseal closure in our patient was presumed to be due to testicular androgen<br />

deficiency. In our patient, relative rather than absolute androgen deficiency seemed to exist,<br />

probably arising from diminished sensitivity <strong>of</strong> the testes to pituitary LH and FSH. There were several<br />

studies reporting sickle cell anemia in association with primary or secondary hypogonadism and zinc<br />

deficiency. <strong>Physicians</strong> should be aware <strong>of</strong> hypogonadism as a possible complication <strong>of</strong> sickle cell anemia<br />

in a young patient, its possible causes, and the importance <strong>of</strong> appropriate and timely treatment.<br />

Recurrent Early Stent Thrombosis Associated with Clopidogrel and Prasugrel Resistance: A Case<br />

Report<br />

Jose A Villamil, MD, Arismendy Nunez, MD, Motaz Moussa, MD, George Fernaine, MD, FACC<br />

INTRODUCTION: Platelet inhibition using a combination <strong>of</strong> aspirin and thienopyridines is the standard<br />

therapy to prevent stent thrombosis after percutaneus coronary intervention (PCI). The etiology <strong>of</strong> stent<br />

thrombosis is multifactorial; however it occurs more commonly in individuals with resistance to<br />

clopidogrel. Clopidogrel resistance has been associated to genetic variability on the CYP 2C19 enzyme<br />

which metabolizes the drug into its active form. Newer third generation thienopyridine prasugrel is a<br />

more potent antagonist <strong>of</strong> P2Y12 receptor. Its antiplatelet activity is claimed to be independent <strong>of</strong><br />

genetic polymorphism <strong>of</strong> CYP2C19; therefore prasugrel is used as the alternative to manage cases <strong>of</strong><br />

clopidogrel resistance. We present a case <strong>of</strong> recurrent acute STEMI due to early thrombosis after PCI,<br />

indicating clinical resistance to both clopidogrel and prasugrel.<br />

CASE PRESENTATION: A 71-year-old Caucasian woman with CAD presented to the ED complaining <strong>of</strong><br />

typical chest pain. Initial EKG showed sinus rhythm and old inferior wall MI. The patient was initially<br />

started on aspirin and clopidogrel (loading dose <strong>of</strong> 600mg) and admitted to the cardiac care unit (CCU).<br />

Later she underwent cardiac catheterization with placement <strong>of</strong> four drug eluting stents, two in left<br />

anterior descending artery (LAD) and two in diagonal artery (D1). Post PCI she continued taking<br />

clopidogrel and aspirin. Two days later, chest pain recurred, and EKG revealed acute anterior wall STEMI<br />

ST. Emergent angiogram showed 100% occlusion <strong>of</strong> LAD and diagonal stents. Successful<br />

revascularization <strong>of</strong> LAD was achieved, and a blood sample was taken for genetic testing (CYP2C19<br />

variant). Patient was transferred to back to the CCU and started on prasugrel for suspected clopidogrel<br />

resistance. Three days later she developed chest pain and EKG showed acute anterior wall STEMI.<br />

Repeated angiogram showed 100% occlusion <strong>of</strong> the LAD, after successful thrombectomy and<br />

angioplasty <strong>of</strong> LAD, patient underwent emergent coronary artery bypass surgery for suspected prasugrel<br />

resistance. Genetic testing showed one copy <strong>of</strong> CYP2C19*2 variant. This mutation is associated with<br />

decreased activity <strong>of</strong> CYP2c19.<br />

DISCUSSION: Thienopyridine resistance may lead to life threatening complications such as<br />

early stent thrombosis. In vitro studies have shown that resistance to prasugrel and clopidogrel occurs in<br />

6% and 45 % <strong>of</strong> patients respectively; however, not all cases <strong>of</strong> laboratory resistance are accompanied<br />

by clinical resistance. In the setting <strong>of</strong> post PCI chest pain, stent thrombosis and thienopyridine<br />

resistance should be suspected. It is important to recognize that resistance to thienopyridines occurs for<br />

both clopidogrel and prasrugel. Further research is needed to identify prasugrel resistance as well as<br />

the subset <strong>of</strong> patients who may be resistant to the thienopyridine class.<br />

Life Threatening Unilateral Emphysematous Pyelonephritis, Managed By Medical Therapy Alone<br />

Mehran Yaghmaie Jehanzeb Khan MD, Karen Beekman MD, Hita Sharma MD, Sam Nia MD<br />

INTRODUCTION: Introduction<br />

Emphysematous pyelonephritis (EPN) is a rare necrotizing infection <strong>of</strong> renal parenchyma characterized<br />

by the production <strong>of</strong> gas in the intra and perirenal tissues. Diabetic patients account for 70–90% <strong>of</strong> all<br />

cases. The infection <strong>of</strong>ten has a fulminating course with mortality up to 50%. It is believed that high<br />

levels <strong>of</strong> glucose in association with inadequate perfusion, lead to a favorable environment for the<br />

growth <strong>of</strong> anaerobic organisms within the kidneys. Other conditions involved in the pathogenesis <strong>of</strong> EPN<br />

include urinary tract obstruction, partially treated sepsis, lymphatic obstruction, lipid metabolism<br />

abnormalities and impaired immune responsiveness. Diabetic microangiopathy by causing slow<br />

transport <strong>of</strong> catabolic products can lead to gas accumulation. Among causative organisms, Escherichia<br />

coli is isolated in 66% cases. Klebsiella, Proteus, Pseudomonas, rarely Clostridium and Candida<br />

species have also been isolated. Patients typically present with fever, abdominal or flank pain, nausea<br />

and vomiting, dyspnea, acute kidney injury, altered sensorium, shock and thrombocytopenia. Crepitus<br />

over the flanks may occur in advanced cases. CT scan is the best tool for diagnosis.<br />

Case presentation<br />

A 62 years old female presented with history <strong>of</strong> left lower quadrant abdominal pain for four days.<br />

Patient had poorly controlled diabetes mellitus(HbA1C 12).Patient described her abdominal pain as<br />

gradually worsening, non-radiating, associated with nausea, and vomiting. Patient also complained <strong>of</strong><br />

subjective fever with chills. Physical examination revealed marked left sided CVA tenderness with<br />

guarding. CT scan <strong>of</strong> the abdomen showed the presence <strong>of</strong> air in left renal collecting system, renal pelvis<br />

and the anterior aspect <strong>of</strong> the urinary bladder. There was heterogeneous enhancement <strong>of</strong> both kidneys,<br />

more prominent on the left, highly suspicious for pyelonephritis. Laboratory results significant for<br />

marked leukocytosis (19,000) and hyperglycemia (550 mg/dl). Patient was promptly started on IV<br />

cipr<strong>of</strong>loxacin, clindamycin and gentamicin were promptly begun On day 3 urine culture grew E. Coli and<br />

antibiotics changed to ertapenem. Tight glycemic control was also achieved. A follow-up CT abdomen<br />

obtained after four days showed global improvement <strong>of</strong> pyelonephritis with absence <strong>of</strong> gas. Because <strong>of</strong><br />

adequate response to antibiotics, scheduled nephrectomy was canceled. Patient was discharged on oral<br />

antibiotics.<br />

Discussion<br />

Our patient is among the very few reported cases <strong>of</strong> emphysematous pyelonephritis managed by<br />

medical therapy alone. Although the gold-standard therapy for EPN is considered to be nephrectomy,<br />

conservative treatment with antibiotics should be considered first. If the patient has significant exudate<br />

along with gas in the renal parenchyma and perinephric tissues, initial percutaneous drainage should be<br />

performed. A recent review Aswathaman et al (2008) , reported that 80% <strong>of</strong> EPN patients were<br />

successfully treated with early initiation <strong>of</strong> percutaneous drainage and antibiotics alone without<br />

requiring nephrectomy.<br />

CIDP Masquerading as Metabolic Polyneuropathy<br />

Jun Zhang, MD, PhD; Other coauthors: Zinah Abdulqader, MD; Dimitry Olivier, MD; Jean Francois, MD;<br />

Sonia Borra, MD<br />

INTRODUCTION:CIDP (Chronic inflammatory demyelinating polyneuropathy) is a chronic neuropathy <strong>of</strong><br />

supposed immune-mediated origin. It is thought to be a common but underdiagnosed disease because<br />

the differentiation can be sometimes very challenging, especially when a metabolic polyneuropathy<br />

could be a plausible explanation for neurological manifestations under conditions such as diabetes and<br />

uremia. Early recognition <strong>of</strong> CIDP is thus crucial as it is a potentially treatable disease.<br />

CASE PRESENTATION: A 61-year-old African <strong>American</strong> man with long history <strong>of</strong> diabetes and<br />

hypertension as well as end stage renal disease presented with progressive weakness <strong>of</strong> both legs for 3<br />

months. It started as difficulty walking while carrying weights then to inability to move completely,<br />

associated with burning sensation over his bilateral foot soles. "Diabetic polyneuropathy" was initially<br />

proposed, but a diagnosis <strong>of</strong> "uremic polyneuropathy" was made after his condition worsened along<br />

with deteriorating kidney function. He started hemodialysis about 2 months ago but no obvious<br />

improvement was observed even with more frequent daily dialysis. On presentation, patient was obese<br />

with BMI <strong>of</strong> 45.7kg/m2, temperature 98F, heart rate 65/min, respiration rate 16/min and BP 174/67.<br />

Physical exam revealed normal mental status with normal cranial nerve function. There was mild<br />

weakness over bilateral upper extremities (4/5 in strength) with thenar atrophy, and a complete loss <strong>of</strong><br />

muscle strength (0/5) over bilateral lower extremities, which were swelling up to the thigh. No<br />

spasticity, rigidity, tremor or fasciculations were observed. The light touch, pain, vibration and<br />

temperature sensations were grossly intact except abnormal pain elicited by fine touch in the soles <strong>of</strong><br />

both feet. The sense <strong>of</strong> position was severely impaired in the lower extremities. Notably, there was a<br />

complete loss <strong>of</strong> deep tendon reflex in all extremities. MRI without gadolinium (due to renal function)<br />

showed multiple degenerative spinal discs, but neither central canal compromise nor acute cerebral<br />

events were observed. An electromyogram and nerve conducting study revealed findings suggestive <strong>of</strong><br />

primary demyelinating polyneuropathy with some axonal lesions. A subsequent cerebrospinal fluid<br />

analysis showed elevated protein level (85.9 mg/dl, normal: 15-45 mg/dl) with zero leukocyte count.<br />

Despite his refusal <strong>of</strong> nerve biopsy, the existence <strong>of</strong> CIDP possibly on the top <strong>of</strong> diabetic or uremic<br />

polyneuropathy was thus proposed, and treatment with prednisone and intravenous immunoglobulin<br />

started. After 3 days, patient began to feel stronger subjectively, and after 5 days, he was able to move<br />

his toes. However, presumably due to preexisting axonal damage from either diabetes or uremia, and<br />

also a relatively delayed recognition <strong>of</strong> CIDP, his recovery was not complete.<br />

DISCUSSION: This case illustrated the challenge and importance <strong>of</strong> recognizing CIDP in patients with<br />

systemic diseases <strong>of</strong> metabolic origin such as diabetes, uremia, etc. Although metabolic dysregulation in<br />

those conditions is frequently associated with neuromuscular complications, CIDP still deserves to be<br />

part <strong>of</strong> the differential if a patient presents mainly symmetric motor polyneuropathy for more than 8<br />

weeks and symptoms cannot be fully explained by metabolic polyneuropathy. A diagnostic workout and<br />

subsequent treatment should be initiated as soon as possible to maximize the chance <strong>of</strong> therapeutic<br />

success.<br />

"What the Heck, I Can’t Move My Neck!"<br />

Heather B Friedman, M.D., Toni Evans, M.D., Beth Susi, M.D.<br />

INTRODUCTION: CASE PRESENTATION: A 30-year-old African <strong>American</strong> male presented to the<br />

Emergency Department with the chief complaint “I can’t move my neck.” He had experienced 1 year <strong>of</strong><br />

progressive neck and back pain, as well as stiffness which was worse when he sat down and better while<br />

walking. His past medical history included a bilateral leg deformity since childhood with corrective<br />

surgery and iron deficiency anemia. Review <strong>of</strong> systems was notable for a 200 pound unintentional<br />

weight loss over the past year, and extreme weakness, in addition to the inability to move his head. He<br />

had no fevers, rashes, eye complaints, other joint pains, or gastrointestinal changes. He took no<br />

prescribed nor over the counter medications. Physical exam revealed a chronically ill-appearing man<br />

who had clear immobility <strong>of</strong> his C-spine. His Schober’s test revealed lumbar flexion <strong>of</strong> only<br />

2cm. Multiple superficial skin erosions were present along his spine and his lower extremities had postsurgical<br />

scars. His abdominal exam was unremarkable but his stool was hemoccult positive. Initial labs<br />

demonstrated a microcytic anemia with an MCV <strong>of</strong> 69 and Hgb <strong>of</strong> 7.8, platelets 552, albumin 2.7, CRP<br />

11.9, ESR 109.<br />

A CT <strong>of</strong> his spine showed findings <strong>of</strong> a diffuse ankylosing process <strong>of</strong> the cervical spine and upper thoracic<br />

spine which was highly suggestive <strong>of</strong> Ankylosing Spondylitis. There was fusion at the craniocervical<br />

junction and markedly irregular C1-C2 articulations. An HLA-B27 was negative, and MRI <strong>of</strong> his entire<br />

spine showed diffuse facet fusion. He also received packed RBC’s and underwent a colonoscopy, which<br />

demonstrated severe inflammation and serpentine ulcerations found in a continuous and<br />

circumferential pattern from the terminal ileum to sigmoid colon, sparing the rectum. The terminal<br />

ileum was severely erythematous and ulcerated; pathology was consistent with Crohn's Disease.<br />

DISCUSSION: The Spondyloarthropathy Disorders are a heterogeneous group <strong>of</strong> arthritidies commonly<br />

associated with Inflammatory Bowel Disease. This case is particularly unusual in that our patient’s initial<br />

presentation <strong>of</strong> his Crohn’s Disease was a fused cervical spine. Typically with spondyloarthropathy,<br />

especially Ankylosing Spondylitis, patients experience increasing low back pain with sacroiliac joint<br />

involvement and the disease progresses cranially. Of the various enteropathic spondyloarthropathy<br />

disorders, only 60% are associated with HLA-B27 positivity, even fewer if African <strong>American</strong> in race;<br />

hence our patient being negative for the marker is not atypical. For treatment <strong>of</strong> his newly diagnosed<br />

Crohn’s, he was started on prednisone along with 6- Mercaptopurine. Given the fact that his spine is<br />

largely fused at this point, treatment with a TNF inhibitor may not benefit his arthritic process, but may<br />

aid in the treatment <strong>of</strong> his Crohn’s Disease.<br />

EGFR mutation in advanced NSCLC<br />

Suheir Khajuria, MD, MPH Second Author: Andrew Schreiber, MD<br />

INTRODUCTION:Non-small cell lung cancer (NSCLC) with brain metastasis is associated with poor<br />

prognosis and a median survival <strong>of</strong> less than one year. Platinum based doublet chemotherapy remains<br />

the treatment <strong>of</strong> choice for the majority <strong>of</strong> patients. NSCLC patients with certain Epidermal Growth<br />

Factor Receptor (EGFR) mutations have shown to benefit from EGFR tyrosine kinase inhibitors.<br />

CASE PRESENTATION: A 60 year old Caucasian female presented with headache, progressive slurring<br />

<strong>of</strong> speech and tingling sensation in her left leg. She had a 60-pack year smoking history and no focal<br />

deficits on examination. CT head revealed numerous masses throughout cerebral hemispheres<br />

consistent with metastatic disease. CT <strong>of</strong> her chest/abdomen revealed an irregular 2.4 X 2.8 cm left<br />

lower lobe lung mass along with a 6.3 cm right hepatic lobe mass. She received whole brain irradiation<br />

initially secondary to her CNS symptoms. Lung biopsy was consistent with adenocarcinoma and liver<br />

biopsy confirmed metastatic disease. She was Cytokeratin 7 positive, Cytokeratin 20 negative, Thyroid<br />

transcription factor-1 positive, suggesting a lung primary (stage IV). Her ECOG performance status was 1.<br />

After palliative chemotherapy was started with Carboplatin and Alimta, she was found to be positive for<br />

EGFR mutation for exon 18. Her imaging studies on Carboplatin/Alimta showed no improvement in her<br />

widely metastatic disease. She was switched to oral Tarceva after 3 cycles <strong>of</strong> Carboplatin/Alimta. Her<br />

symptoms <strong>of</strong> fatigue, weakness, and nausea showed significant improvement with treatment side<br />

effects <strong>of</strong> only a mild acneiform rash on her face and mild diarrhea. After 6 weeks <strong>of</strong> Tarceva, imaging<br />

studies revealed reduction in size <strong>of</strong> the lung mass and hepatic lesion. She resumed work and was<br />

continued on Tarceva.<br />

DISCUSSION: Approximately 15% <strong>of</strong> the U.S. population with advanced NSCLC is found to have EGFR<br />

mutations within the tyrosine kinase domain. These are more commonly seen in Asian, non-smoker<br />

females and occur within EGFR exons 18-21. Over 90% <strong>of</strong> mutations occur within exon 19 and 21.<br />

Erlotinib (EGFR tyrosine kinase inhibitor) has shown improved survival as a first line therapy in chemonaive<br />

patients having NSCLC with brain metastasis. In this case, patient was positive for exon 18 EGFR<br />

mutation and had already received standard chemotherapy prior to Erlotinib without a clinical<br />

response. Treatment with Erlotinib showed regression <strong>of</strong> disease and improved quality <strong>of</strong> life. Studies<br />

have also supported that development <strong>of</strong> rash as in this patient is consistent with the likelihood <strong>of</strong><br />

clinical benefit from Erlotinib. Thus, all stage IV lung Adenocarcinoma patients presenting with brain<br />

metastasis should be tested for EGFR mutations. Trials assessing the role <strong>of</strong> EGFR inhibitors as a single<br />

agent and in combination therapy for such patients are in progress.<br />

Get the Lead Out: An Unusual Case <strong>of</strong> Cryptococcal Endocarditis<br />

Ross M Nesbit, MD Beth Susi, MD FACP James Horton, MD David Weinrib, MD<br />

INTRODUCTION: A 55yo African <strong>American</strong> male presented with worsening fatigue and<br />

“sluggishness”. He had felt well until 2-3 months prior, when he developed progressive fatigue, fevers,<br />

chills and a 20 pound weight loss. PMH included prophylactic automatic implantable cardioverterdefibrillator<br />

[AICD] placement in February 2010 for non-ischemic cardiomyopathy, as well as<br />

hypertension and diabetes. Review <strong>of</strong> systems was unremarkable; he denied palpitations or the<br />

sensation <strong>of</strong> his AICD firing.<br />

CASE PRESENTATION: Physical exam showed low grade fever and an initial BP 88/53 and HR 112,<br />

both <strong>of</strong> which corrected with fluid resuscitation. Blood cultures were obtained which were positive for<br />

yeast on day 3 <strong>of</strong> incubation. This prompted an HIV antibody test and confirmatory Western blot; both<br />

returned positive. Initial transthoracic echocardiography revealed an EF <strong>of</strong> 35% and moderate mitral<br />

regurgitation; subsequent transesophageal echocardiography showed a mitral valve vegetation with<br />

stranding and a mobile mass on the apical portion <strong>of</strong> the right ventricular [RV] AICD lead. Additionally,<br />

the blood culture growth was definitively identified as Cryptococcus ne<strong>of</strong>ormans. At the time <strong>of</strong> the<br />

AICD removal, the RV ICD lead was noted to be covered in a thin, white film. Treatment with<br />

amphotericin and 5-flucytosine was initiated, and after the removal <strong>of</strong> the device there were no<br />

additional positive blood cultures, including fungal cultures.<br />

DISCUSSION: There is a dearth <strong>of</strong> information regarding Cryptococcal endocarditis, with only five<br />

reported cases thus far in the literature, and no cases involving a pacemaker or AICD. Available data for<br />

infection following ICD or pacemaker implantation puts the risk <strong>of</strong> infection between 0.8 and 5.7%,<br />

depending on the implanting physician’s procedural volume. More recent data reveals a device-related<br />

infection rate <strong>of</strong> less than 1% for initial device implantations. True device endocarditis is even less<br />

common, with recent literature showing an incidence <strong>of</strong> 0.5% <strong>of</strong> all device insertions. The<br />

immunocompromised patient presents a greater treatment challenge, especially in the case <strong>of</strong><br />

cryptococcal organ involvement. Our treatment was like that <strong>of</strong> cryptococcal meningitis, using induction<br />

therapy with intravenous liposomal amphotericin and 5-flucytosine, followed by maintenance therapy<br />

with fluconazole. Removal <strong>of</strong> the device was critical, as its presence would serve as a continued nidus<br />

for infection. Fortunately, device interrogation revealed no prior ventricular arrhythmias, and thus the<br />

ICD was able to be removed. As new data emerges supporting the use <strong>of</strong> implantable defibrillators and<br />

synchronous pacing, and with the growing prevalence <strong>of</strong> chronic HIV infection and immunosuppression,<br />

such opportunistic device infection may be a more commonly encountered infectious entity in years to<br />

come.<br />

Chronic Cocaine Use Can Be Associated With Sick Sinus Syndrome<br />

Megha Sawhney, MD Co-authors: Ankit Garg, MD Timothy Lane, MD Yashaswi Pokharel, MD<br />

INTRODUCTION: The sick sinus node syndrome usually occurs because <strong>of</strong> nodal fibrosis and the<br />

presentation frequently includes SA nodal pauses, arrest, and exit block. A sinus pause or arrest is<br />

defined as the transient absence <strong>of</strong> sinus P waves on the EKG that may last from 2 sec to few minutes.<br />

Chronic cocaine use can also produce sinoatrial block.This case demonstrates the presentation <strong>of</strong> sick<br />

sinus syndrome in a man with chronic cocaine use.<br />

CASE PRESENTATION: A 57 year old man presented to ED with syncope. He was walking to his<br />

bathroom after waking up when he felt dizzy, lightheaded, and fell on the floor unconscious. He denied<br />

any premonitory symptoms <strong>of</strong> chest pain, SOB, or palpitations. No history <strong>of</strong> seizures or head trauma<br />

was obtained. Physical exam was unremarkable and orthostatics were normal. lnitial labs including CBC,<br />

metabolic panel were normal. Imaging studies including CXR and CT- scan <strong>of</strong> the brain were negative.<br />

Urine drug screen(UDS) was positive for cocaine. EKG showed bradycardia and normal PR, QRS and QT<br />

interval. During his first night in the telemetry unit he was noted having 2 sinus pauses <strong>of</strong> >5 sec,<br />

followed by few episodes with sinus pause >3sec on the second night when he was completely<br />

asymptomatic. Permanent transvenous pacemaker was inserted on day 4. Previous hospitalizations for<br />

chest pain related to cocaine also demonstrated bradycardia with similar sinus pauses. His 6 month<br />

follow up did not show any new admissions for chest pain or syncope.<br />

DISCUSSION: Cocaine induced bradyarrhythmias have not been described frequently despite the<br />

common use <strong>of</strong> cocaine in US, but has clearly been described in multiple case reports <strong>of</strong> sinoatrial block.<br />

Acute cocaine intoxication produces sinoatrial block. The mechanism <strong>of</strong> block is attributed to fall in the<br />

resting potential and decrease in the amplitude and Vmax <strong>of</strong> phase 0 <strong>of</strong> action potentials <strong>of</strong> the resting<br />

cardiac muscle fibres with automaticity. There may be several mechanisms for electrophysiological<br />

changes that include depressed SA nodal automaticity, SA nodal exit block, spasm <strong>of</strong> sinoatrial artery,<br />

inferior MI, chronic ischemia and resulting fibrosis <strong>of</strong> the SA node. Our patient received a permanent<br />

pacemaker because <strong>of</strong> recurrent and persistent nature <strong>of</strong> this association. The physicians should be<br />

aware that cocaine use can present with a sick sinus like syndrome and recurrent syncope.<br />

INTRODUCTION:Central nervous system (CNS) involvement is a well recognized complication <strong>of</strong><br />

Epstein-Barr virus (EBV) infection, the most common form being encephalitis and CNS lymphoma. Rarely<br />

EBV is also implicated in pathogenesis <strong>of</strong> vasculopathy. We describe a case <strong>of</strong> a young individual with<br />

CNS vasculopathy caused by EBV who presented as acute ischemic stroke.<br />

CASE PRESENTATION: Patient is a 35 year old male who presented with symptoms <strong>of</strong> severe headache<br />

and loss <strong>of</strong> balance for one day. He has past medical history <strong>of</strong> ulcerative colitis, hypertension,<br />

dyslipidemia and recent deep vein thrombosis. Initial assessment revealed stable vitals and normal<br />

physical examination except left sided weakness. Investigations revealed normal complete blood count,<br />

basic metabolic pr<strong>of</strong>ile, liver function tests, coagulation parameters and chest radiograph. Magnetic<br />

resonance imaging <strong>of</strong> the brain showed acute ischemia versus neoplasm in the corpus callosum, right<br />

basal ganglia and anterior aspect <strong>of</strong> right thalamus. Patient was started on intravenous dexamethasone<br />

and neurosurgery was consulted for possible biopsy. Also, computed tomography scan <strong>of</strong> the brain with<br />

contrast was obtained to rule out hemorrhage which showed a rim-like contrast enhancement<br />

suggestive <strong>of</strong> an abscess. In the meantime his motor function continued to worsen and he spiked fever.<br />

Pathology from the stealth biopsy <strong>of</strong> the frontal mass showed subacute encephalomalacia with reactive<br />

and inflammatory changes, subacute vasculopathy with thrombosis and acute cerebral infarct with EBV<br />

probe positive. The EBV serology showed reactivation pattern. Patient was discharged to acute<br />

rehabilitation on acyclovir. His strength improved markedly after few months <strong>of</strong> physical therapy.<br />

DISCUSSION: The role <strong>of</strong> EBV in pathogenesis <strong>of</strong> vasculitis has been speculated previously but what<br />

makes our case unique is the subacute vasculopathy and the fact that both endothelial cells and cells<br />

within the walls <strong>of</strong> the blood vessel were positive for EBV and those same blood vessels were<br />

thrombosed. As all the work up to determine any secondary cause <strong>of</strong> vasculopathy was negative in this<br />

patient, we conclude that the most likely etiology was EBV infection. This case emphasizes the<br />

recognition <strong>of</strong> growing spectrum <strong>of</strong> diseases caused by EBV.<br />

Headache in a young female<br />

Shubhi Agrawal, MD<br />

INTRODUCTION: Headache is a very common yet challenging problem. The constellation <strong>of</strong> symptoms<br />

among various diagnoses is <strong>of</strong>ten overlapping and presentation can be varied. Here we report a case <strong>of</strong><br />

headache in a healthy teenager.<br />

CASE PRESENTATION: A 17 year old Caucasian female presented to our hospital with complaints <strong>of</strong><br />

severe throbbing, fronto-temporal headache for 5 days; associated with photophobia, nausea and non<br />

projectile vomiting. The patient and her parents denied any history <strong>of</strong> fever, seizures or altered mental<br />

status. There was no personal or family history <strong>of</strong> migraine. On examination she was alert, fully oriented<br />

and vital signs were stable. Neurological exam including higher mental functions, cranial nerves, motor<br />

and sensory systems, coordination and gait was normal. There was marked photophobia but pupillary<br />

size and reflexes, external ocular movements, visual fields and fundoscopy were normal. Presence <strong>of</strong><br />

neck rigidity was questionable but Kernig's sign was absent. Examination <strong>of</strong> the skin, lymph nodes,<br />

oropharynx, cardiorespiratory system and abdomen was benign. A non-contrast computerized<br />

tomographic scan <strong>of</strong> the brain was unremarkable. Complete blood count and basic metabolic pr<strong>of</strong>ile<br />

were normal. A diagnosis <strong>of</strong> Status Migrainosus was made and dexamethasone and promethazine were<br />

administered. However, there was minimal symptom relief. Later, the family physician reported a fever<br />

<strong>of</strong> 102 F two days prior, so a lumbar puncture was performed. Cerebrospinal fluid was clear, with<br />

opening pressure <strong>of</strong> 300 mm <strong>of</strong> water, nucleated cell count <strong>of</strong> 580 cells with 94%lymphocytes, glucose<br />

<strong>of</strong> 42mg/dl (blood glucose 107mg/dl) and proteins <strong>of</strong> 157mg/dl. Headache and nausea were much<br />

relieved by the procedure and intravenous acyclovir was started empirically. CSF studies for<br />

Cryptococcal antigen, India Ink preparation, VDRL, FTA, Herpes Simplex PCR, Gram Stain and cultures<br />

were negative. On the third day, a painless, fine, red, maculo-papular rash appeared over the right C7<br />

dermatome. She also gave a history <strong>of</strong> chicken pox at the age <strong>of</strong> 3 years. So PCR for Varicella Zoster virus<br />

was ordered and was positive. She was discharged home on intravenous acyclovir for 10 days and<br />

reported complete recovery.<br />

DISCUSSION: Neurological complications from reactivation <strong>of</strong> Varicella Zoster virus have been<br />

described extensively in immunocompromised and elderly patients but rarely in young<br />

immunocompetent patients. Due to its indolent course it is likely to be misdiagnosed in the latter group,<br />

especially in the absence <strong>of</strong> a typical rash. Also, patients <strong>of</strong>ten take over the counter medications like<br />

Paracetamol and Ibupr<strong>of</strong>en for headache, that may mask fever, further complicating the diagnosis.<br />

Timely diagnosis is imperative as it is a treatable condition that can potentially lead to complications like<br />

encephalitis and cerebral vasculitis among others.<br />

Also, the possibility <strong>of</strong> subclinical meningitis in all patients with Herpes Zoster needs to be investigated<br />

further.<br />

Troubling Spinal Osteomyelitis: Candida In An Immunocompetent Patient<br />

Abidemi Bobby Akande, M.D., M.P.H. Other authors: John S. Czachor, M.D., Alpa Desai, MBBS. Wright<br />

State University Department <strong>of</strong> Internal Medicine<br />

INTRODUCTION: Significant Candida infections are quite rare in immunocompetent patients without<br />

known risk factors. 1 Candida osteomyelitis <strong>of</strong> the spine in non-intravenous drug users is exceedingly<br />

rare, with only 59 cases reported in the literature between 1966 and 2000. 2,4,5 We report a case <strong>of</strong><br />

Candida albicans osteomyelitis in a previously healthy 30-year-old Caucasian male with no apparent risk<br />

factors for fungal infections.<br />

CASE PRESENTATION: A 30-year-old male presented to emergency room (ER) with a chief complaint <strong>of</strong><br />

back pain. Diagnosed as back strain, he was discharged with analgesics but returned several times back<br />

to the ER. The patient had complaints <strong>of</strong> significant stabbing mid-back pain described as intermittent,<br />

aggravated by movement and relieved by rest. There was no fever or chills. Although he initially denied<br />

night sweats, he later reported several episodes. He is a tree trimmer by pr<strong>of</strong>ession but denied history<br />

<strong>of</strong> penetrating injury. He repeatedly denied a history <strong>of</strong> intravenous drug use. Physical exam was<br />

significant only for tenderness to palpation in the T5-10 vertebrae level. His neurological exam was<br />

unremarkable and there were no findings to suggest needle punctures or skin infections. An MRI<br />

showed thoracic spine disease consistent with osteomyelitis, diskitis and left paraspinal abscess at the<br />

T10-11 level. Percutaneous paraspinal aspirate isolated only Candida albicans. Treatment was started in<br />

the hospital with high dose fluconazole and the patient was discharged on fluconazole 400 mg orally<br />

daily. He was re-admitted 1 month later for worsening back pain and underwent surgical debridement<br />

<strong>of</strong> the affected area. Again, C. albicans was the only organism isolated. He was discharged once again on<br />

fluconazole which he continued for 3 months to complete his course <strong>of</strong> therapy. He remains clinically<br />

free <strong>of</strong> infection at this time.<br />

DISCUSSION: The majority <strong>of</strong> Candida osteomyelitis cases involve the lower thoracic and upper lumbar<br />

vertebrae, as evidenced by this patient. In contrast, however, is that the age predominance is mostly<br />

amongst middle-aged individuals. 2 Greater than eighty percent <strong>of</strong> patients complain <strong>of</strong> back pain. 2,3<br />

Diagnosis is <strong>of</strong>ten delayed due to the insidious onset and the relatively non-infectious presentation <strong>of</strong><br />

this entity. 5,7 Candida albicans is the most frequent isolate <strong>of</strong> all the Candida species. 4 Risk factors for<br />

invasive infections include immunocompromised states such as HIV/AIDS, glucocorticosteroid<br />

administration, cancer chemotherapy, neutropenic states, recent use <strong>of</strong> broad spectrum antibiotics;<br />

injection drug use, and indwelling venous catheters. 7 No such risk factors were identified in this case.<br />

Prolonged antifungal therapy is essential for successful treatment <strong>of</strong> Candida osteomyelitis. 6 There is<br />

usually a good response to fluconazole. 6 Significance <strong>of</strong> follow up MRI with worsening disease despite<br />

clinical improvement remains unclear. 8 The role <strong>of</strong> surgery remains to be further delineated. 8 It was only<br />

after surgical debridement that our patient had steady improvement.<br />

A CASE OF AUTOIMMUNE LYMPHOPROLIFERATIVE SYNDROME<br />

Sado Al Bitar, M.D., Kim Jordan, M.D.<br />

INTRODUCTION: INTRODUCTION: Autoimmune Lymphoproliferative Syndrome (ALPS) is a relatively<br />

new disease first described in 1995. This inherited immunodeficiency disorder is considered a pediatric<br />

illness, generally diagnosed before age 5, but the disease can present in adulthood. Abnormal<br />

lymphocyte apoptosis and lymphoid cell accumulation lead to lymphadenopathy, hepato- splenomegaly,<br />

hypergammaglobulinemia, and autoimmune disease. The incidence <strong>of</strong> lymphoma is significantly<br />

increased. Though ALPS is rare in adulthood, internists should be cognizant <strong>of</strong> its presentation,<br />

treatment, and <strong>of</strong>fer genetic counseling if diagnosed.<br />

CASE PRESENTATION: Case: A 42 yo female with a history <strong>of</strong> psychotic disorder presented with 3 days<br />

<strong>of</strong> left upper quadrant abdominal discomfort, preceded by 3 weeks <strong>of</strong> diarrhea. Stool was watery,<br />

brown, with no blood or mucus. She had no other complaints. Examination revealed tender<br />

splenomegaly, but no lymphadenopathy or hepatomegaly. Mild anemia (Hb 11.4), low IgA (21) and<br />

elevated LDH (154) were noted. Stool culture was positive for Blastocystis hominis, which was<br />

considered a colonizing organism, was not treated, and her diarrhea subsided within 1 day <strong>of</strong><br />

admission. Imaging showed massive splenomegaly, mesenteric and retroperitoneal lymphadenopathy.<br />

Bone marrow revealed erythroid hyperplasia, but was negative for abnormal lymphoid population by<br />

flow cytometry immunophenotyping. Splenectomy was performed and pathology showed T-zone<br />

hyperplasia with reactive immunoblasts featuring a phenotypically distinct T-cell population, suggestive<br />

<strong>of</strong> ALPS.<br />

DISCUSSION: DISCUSSION: ALPS is a genetic disorder characterized by a defect in the tumor necrosis<br />

factor receptor gene superfamily ( TNFRSF6) which encodes for the Fas cell surface receptor and T cells<br />

that express alpha-beta T-cell receptor, but are CD 4 and CD 8 negative. The Fas cell surface receptor<br />

plays a major role in lymphocyte apoptosis. Defective apoptosis leads to accumulation <strong>of</strong><br />

immunogenic “alpha-beta double negative T-cells” in the peripheral blood and lymphoid organs, with<br />

resultant splenomegaly, lymphadenopathy, and possible autoimmune cytopenias. The incidence <strong>of</strong><br />

lymphoma (Hodgkin and non Hodgkin) is significantly increased. The clinical presentation <strong>of</strong> individuals<br />

with ALPS is highly variable; penetrance depends on site <strong>of</strong> mutation. Several subtypes exist<br />

including: ALPS-FAS (most common); ALPS-sFAS (somatic mutation); ALPS-LG (ligand mutation); ALPS-<br />

CASP10 (caspase 10 mutation); and ALPS-U (genetic mutation unidentified). Definitive diagnosis<br />

requires presence <strong>of</strong> non-malignant, non-infectious lymphadenopathy in 2 nodal chains, and/or<br />

splenomegaly for 6 months, plus abnormal lymphocyte apoptosis assay and/or presence <strong>of</strong> FAS pathway<br />

genetic mutation. Many patients require no treatment though genetic counseling is recommended<br />

given the increased association <strong>of</strong> malignancy and autoimmune disorders. Splenectomy may be needed<br />

in cases <strong>of</strong> severe hypersplenism, as well as glucocorticoid therapy for autoimmune hemolytic anemia<br />

and thrombocytopenia. IVIG, cyclosporin A, and methotrexate patients have been used to treat<br />

immune cytopenias refractory to splenectomy and steroid treatment.<br />

Sore Throat and Fever… Look Beyond Infection!<br />

Rasha Al-Bawardy, MD, M Chadi Alraies MD FACP<br />

INTRODUCTION:Infectious mononucleosis (IM) is a self-limiting disease caused by Epstein-Barr virus<br />

(EBV). Patients usually present with malaise, fatigue, fever, lymphadenopathy and pharyngitis. IM can<br />

cause a reactive proliferation <strong>of</strong> lymphocytes that could mimic large granulocytic lymphocyte (LGL)<br />

leukemia. We report a case <strong>of</strong> atypical IM with absolute neutropenia, LGL lymphocytosis simulating LGL<br />

leukemia.<br />

CASE PRESENTATION: A 42-year-old man who works for the Justice Department stationed in Ghana<br />

presented with 3-day history <strong>of</strong> headache, fatigue, fever (105°F) and sore throat. He was treated with<br />

anti-malarial and antibiotics. Few weeks later, fever continues with drenching sweats and was flown to<br />

the US for further work up. On presentation to our hospital he was afebrile, had few small submental<br />

lymphadenopathy, oral thrush and papular rash on his back. Laboratory findings were significant for<br />

WBC 3.0k/uL, absolute neutrophil count (ANC) 0, hemoglobin 12.9g/dL, platelets 587k/uL, normal<br />

electrolytes, and elevated CRP12.2 mg/dL. Peripheral blood smear showed many large granular<br />

lymphocytes and 19% LGL on flow cytometry. He had elevated EBV-IgG >8AI (normal<br />

DISCUSSION: Neutropenia and increased LGL levels is a rare presentation <strong>of</strong> infectious mononucleosis<br />

which mimics LGL leukemia. LGL is an uncommon type <strong>of</strong> leukemia that has few subtypes, some with<br />

rapid deterioration. The diagnosis <strong>of</strong> LGL leukemia is based on the presence <strong>of</strong> an LGL lymphocytosis,<br />

characteristic immunophenotype, and confirmation <strong>of</strong> clonality using TCR gene rearrangement studies.<br />

Reactive LGL lymphocytosis can be seen in viral infections but the differentiation between reactive and<br />

true LGL leukemia can be challenging. In most reported cases <strong>of</strong> atypical infectious mononucleosis there<br />

is no evidence <strong>of</strong> T-cell monoclonality. To our knowledge, this is a unique case <strong>of</strong> infectious<br />

mononucleosis with mild expansion <strong>of</strong> TCR-VB14. In this case, given the spontaneous recovery and the<br />

unusual immunophenotype expression lead to the diagnosis <strong>of</strong> Infectious mononucleosis.<br />

Medicine<br />

INTRODUCTION:Organic acidemias, also known as organic acidurias are group <strong>of</strong> metabolic disorders<br />

resulting from enzyme deficiency, usually present in the newborn period or early childhood. We report a<br />

rare case <strong>of</strong> late onset glutaric aciduria- type 2(GA-2) in a 42- year old Caucasian female presenting as<br />

unexplained anion gap metabolic acidosis with osmolar gap.<br />

CASE PRESENTATION: A 42-year-old Caucasian female with no significant medical history presented to<br />

our emergency department (ED) with malaise for 2 days, nausea, vomiting and confusion for a day. Her<br />

history was negative for any fever, toxic ingestion, liver disease, diabetes, psychiatric disorder, recent<br />

prescription medication or drug use and symptoms <strong>of</strong> neurological deficit. Her detailed review <strong>of</strong><br />

symptoms ,past medical, family and treatment history were non contributory. Her physical examination<br />

was significant for sinus tachycardia, signs <strong>of</strong> dehydration, confusion, somnolence and loss <strong>of</strong><br />

orientation to time place and person. No meningeal or focal neurological signs were present on physical<br />

examination and rest <strong>of</strong> the physical examination was benign. The intial work up for confusion in the ED<br />

revealed anion gap metabolic acidosis. Further evaluation revealed she had serum osmolar gap with<br />

elevated serum osmolarity and high urinary anion gap. Additional laboratory work up revealed she had<br />

low blood glucose, low TSH, high free T3, free T4, high ammonia levels and ketones in her serum. Her<br />

toxicology studies were negative for any common toxins. She underwent urgent dialysis for possible<br />

toxic ingestion and improved. Her metabolic pr<strong>of</strong>ile was elusive for any common cause <strong>of</strong> metabolic<br />

acidosis but suggestive <strong>of</strong> inborn error in metabolism driven by catabolic state driven by<br />

hyperthyroidsm. Further diagnostic work revealed she had elevated urinary glutaric acid, 2-OH gluatric<br />

acid, 2-OH gluatric lactone, ethylmalonic acid, isovalerylglycine, hexanoylglycine and suberylglycine<br />

suggestive <strong>of</strong> GA-2. She also had low serum carnitine levels. She underwent genetic testing for GA-2<br />

mutations which revealed she is heterozygous for 2 sequence changes <strong>of</strong> ETFB gene which codes for<br />

multiple acyl CoA dehydrogenase (MADD) the enzyme deficient in GA-2. Further evaluation <strong>of</strong> her<br />

deranged thyroid function revealed she had Grave’s disease and underwent total thyroidectomy and is<br />

currently on levothyroxine replacement. She is currently being treated with carnitine for GA-2 and is<br />

asymptomatic<br />

DISCUSSION: GA-2 is a very rare autosomal recessive disorder which usually presents in early<br />

childhood. Our patient who was heterozygous for this disorder became encephalopathic, hypoglycemic,<br />

ketotic and hyperammonemic from excessive production <strong>of</strong> organic acids due to relative deficiency <strong>of</strong><br />

MADD due to hypermetabolic state precipitated by hyperthyroidism.<br />

Unusual Cause Of Obscure Overt Gastrointestinal Bleeding Diagnosed With Spirus Enteroscopy In<br />

Patient With Tuberous Sclerosis<br />

Muhammad Bawany, MD Co- Authors: Soukayna Rkaine, MD., Ali Nawras, MD. FACG<br />

INTRODUCTION: Tuberous sclerosis complex (TSC) is an autosomal dominant disorder characterized by<br />

the development <strong>of</strong> benign neoplasms (hamartomas) <strong>of</strong> the skin and internal organs. It involves the<br />

neurological system in most cases, in addition to the skin, the kidneys and the lungs. The Involvement <strong>of</strong><br />

gastrointestinal (GI) system is uncommon, rarely <strong>of</strong> clinical relevance, and not well described in<br />

literature. This involvement varies from benign angiomyolipomas, neuroendocrine tumors, hamartomas<br />

polyps and stromal tumors to invasive rectal adenocarcinoma. We report a patient known to have TSC,<br />

presented with recurrent obscure overt gastrointestinal bleeding due to a large Jejunal submucosal<br />

undifferentiated tumor diagnosed by Spirus enteroscope.<br />

CASE PRESENTATION: A 39 years old Caucasian female, known to have TSC with multi-organ<br />

involvement including kidney, lung and liver, presented to our hospital with a complaint <strong>of</strong> melena for<br />

three days. She denied any abdominal pain, nausea, vomiting hematemesis or hematochezia. On<br />

physical examination, she had normal vital signs. The abdomen was s<strong>of</strong>t, nontender with positive bowel<br />

sounds. Her blood test revealed hemoglobin <strong>of</strong> 6.7 g/dl and hematocrit <strong>of</strong> 20. Prior to this episode the<br />

patient had recurrent episodes <strong>of</strong> obscure overt GI bleeding in the form <strong>of</strong> melena over the course <strong>of</strong><br />

one year. She had two previous upper endoscopies revealing multiple small polyps in the stomach and<br />

duodenum. None <strong>of</strong> the polyps had stigmata <strong>of</strong> bleeding. She also had two negative colonoscopies. The<br />

patient was admitted to the hospital, received blood transfusion and underwent upper gastrointestinal<br />

endoscopy, which revealed again multiple small non-bleeding sessile polyps in the stomach and<br />

duodenum. The colonoscopy was unremarkable. Capsule endoscopy was done and revealed fresh blood<br />

in the jejunum without identifying the source. Enteroscopy was then performed using spirus<br />

enteroscope, which showed large (30 mm X 25 mm) submucosal, umbilicated and ulcerated mass at the<br />

proximal jejunum. The mass was biopsied and the site was tattooed using India ink. The biopsy was<br />

unremarkable. Surgical resection <strong>of</strong> the mass was then performed. The gross pathology <strong>of</strong> the mass<br />

revealed 67 mm X 30 mm well circumscribed submucosal gray-white mass with a wall thickness <strong>of</strong> 0.3<br />

cm. The immunostains that might be helpful in delineating its nature were negative. The pathological<br />

diagnosis <strong>of</strong> the mass was reported as undifferentiated malignant neoplasm. Up to date (6 months post<br />

surgical resection) the patient had no further episodes <strong>of</strong> GI bleeding and her Hemoglobin level stayed<br />

normal.<br />

DISCUSSION: To our knowledge, our patient is the first reported patient with TSC and large<br />

undifferentiated malignant neoplasm <strong>of</strong> the jejunum causing significant recurrent obscure overt GI<br />

bleeding and the first to be diagnosed by using Spirus enteroscope and then successfully treated<br />

surgically.<br />

A Crippling Presentation Of Neur<strong>of</strong>ibromatosis I<br />

Keaton M Bullen, DO, PGY-2 Second Author: Rex Wilford, DO, RPh<br />

INTRODUCTION:Neur<strong>of</strong>ibromatosis type 1 (NF-1) is an autosomal dominant neurocutaneous disorder<br />

characterized by peripheral neur<strong>of</strong>ibromas, axillary freckling and cafe-au-lait spots. Most NF-1 patients<br />

are diagnosed in childhood. Though it is a relatively common disease, cervical cord compression from<br />

plexiform neur<strong>of</strong>ibromas is a sporadic finding in these individuals. We present an adult with previously<br />

undiagnosed NF-1 with neurologic deficits from plexiform neur<strong>of</strong>ibroma induced cervical cord<br />

compression.<br />

CASE PRESENTATION: A 43-year-old African <strong>American</strong> male, with no known past medical history,<br />

presented with upper and lower extremity weakness, paresthesias and spasticity. Years prior, he had<br />

been seen multiple times in the emergency room for back pain and burning sensations, but never had a<br />

complete neurologic workup. His most recent symptoms began with lower extremity weakness seven<br />

months prior to arrival, which progressed to proximal lower extremity contractions and inability to<br />

ambulate. He denied family history <strong>of</strong> neurologic disease. Physical exam revealed decreased muscle<br />

strength in distal upper extremities and proximal lower extremities, mostly affecting grip strength and<br />

hip flexors. Pateller reflexes were 3+ bilaterally and sensation was decreased in the distal<br />

fingers. Dermatologic exam revealed extensive right-sided freckling and there were two large macules<br />

present, which were consistent with cafe-au-lait spots.<br />

Magnetic resonance imaging revealed bilateral plexiform neur<strong>of</strong>ibromata expanding the neural<br />

foramina from C2-C3 through C6-C7. There was a large pedunculated neur<strong>of</strong>ibroma arising from C6-C7<br />

and a complex mass compressing the cord from C2-C5. The patient underwent tumor debulking surgery<br />

with posterior C2-C6 fusion. Microscopic exam <strong>of</strong> the surgical specimen revealed a lesion infiltrating the<br />

peripheral nerve and sensory ganglion in a pattern suggestive <strong>of</strong> a neur<strong>of</strong>ibroma. His postoperative<br />

course was uneventful, and he was discharged to an acute rehabilitation facility with improving strength<br />

and mobility in his previously affected extremities.<br />

DISCUSSION: It is essential to recognize subtle signs <strong>of</strong> NF-1, such as axillary freckling and cafe-au-lait<br />

spots, in patients without clinically obvious disease. Identifying NF-1 patients can allow early detection<br />

and treatment <strong>of</strong> complications, such as cord compromising lesions, thus avoiding pain, weakness, and<br />

even paresis. Plexiform neur<strong>of</strong>ibromas causing cervical cord compression is a known consequence <strong>of</strong><br />

NF-1, but it is infrequently reported. Most case series include younger individuals and there is a strong<br />

focus on the surgical management <strong>of</strong> the neur<strong>of</strong>ibromas. There is still limited data regarding the natural<br />

history <strong>of</strong> a benign neur<strong>of</strong>ibroma, the utility <strong>of</strong> routine imaging, long-term prognosis, and the<br />

importance <strong>of</strong> follow up for these individuals.<br />

Crohn's Disease versus Carcinoma <strong>of</strong> Bladder: A Diagnostic Dilemma.<br />

Sriranjini Chilkunda Ramaswamy, MD, Jasleen Kaur Pannu, MD, Hardeep Rai, MD,Richard Nord, MD,<br />

Lawrence Goldstein, MD, FCCP.<br />

INTRODUCTION:Inflammatory bowel disease (IBD) has been known to bear a wide array <strong>of</strong> extra<br />

intestinal manifestations(EM) and complications. It is also known to be an independent risk factor for<br />

genitourinary malignancies. Benign tumors <strong>of</strong> urinary bladder occurring in association with Crohn’s<br />

disease have been rarely reported. These “cancer mimics” pose a perplexing diagnostic dilemma for<br />

clinicians. We report a case <strong>of</strong> a young man with Crohn’s disease who presented with a benign bladder<br />

mass as an extraintestinal manifestation <strong>of</strong> his disease.<br />

CASE PRESENTATION: A 42 year old white male diagnosed with Crohn’s disease one year prior<br />

developed dysuria associated with bilateral inguinal discomfort and constipation. Physical examination<br />

was normal. He was evaluated with a CT <strong>of</strong> the abdomen using a renal stone protocol. No stones were<br />

identified but inflammation was noted in the region <strong>of</strong> the terminal ileum. A subsequent colonoscopy<br />

revealed a normal colon but a stricture was noted in the terminal ileum. Small bowel follow through<br />

confirmed severe narrowing <strong>of</strong> the terminal ileum. The pain responded to metronidazole but multiple<br />

recurrences required treatment with metronidazole then cipr<strong>of</strong>loxacin. Recurrent symptoms a year later<br />

led to a repeat urologic evaluation which was notable for hematuria on urinalysis. A subsequent<br />

cystoscopy revealed a mass in the dome <strong>of</strong> the bladder. Repeat cystoscopy two months later<br />

demonstrated a persistent but less inflamed appearing mass. Subsequent biopsy was read as a<br />

superficial low grade urothelial carcinoma. During this period abdominal discomfort and dysuria<br />

associated with bowel irregularities waxed and waned. A follow-up abdominal CT revealed an<br />

inflammatory mass in the right lower quadrant from the terminal ileum to the dome <strong>of</strong> the bladder<br />

without definitive fistula formation. Due to persistent right lower quadrant discomfort and constipation<br />

with the above CT scan findings, consultation with a colorectal surgeon was undertaken but surgery was<br />

deferred because <strong>of</strong> the urologic issue. Subsequent bladder tumor fulcurization revealed fibrovascular<br />

tissue, smooth muscle and adipose tissue with acute and chronic inflammation and reactive features<br />

with no evidence <strong>of</strong> carcinoma.<br />

DISCUSSION: Radiographic and cystoscopic evidence <strong>of</strong> bladder mass is most commonly known to<br />

represent carcinoma. Rarely, Crohn’s disease may present with a bladder mass as a result <strong>of</strong><br />

compression by an enlarging intrabdominal focus <strong>of</strong> inflammation. But, the fact that Crohn’s disease is<br />

an independent risk factor for transitional cell carcinoma <strong>of</strong> bladder can not be ignored. Meticulous<br />

pathology interpretation following biopsy is warranted to differentiate low grade cancers from severe<br />

inflammation.Also regional enteritis should be considered an important differential in healthy adults<br />

with bladder mass and no risk factors for carcinoma <strong>of</strong> bladder.<br />

Mixed Autoimmune Hemolytic Anemia presented after Chronic Rejection <strong>of</strong> Kidney Transplant - A<br />

Case Report.<br />

Ayham Deeb, MD<br />

INTRODUCTION: Mixed Autoimmune hemolytic anemia (AIHA) is uncommon, it can cause severe<br />

hemolysis which could be responsive or resistant to conventional treatment with steroids or<br />

plasmapheresis. Fifty percent <strong>of</strong> cases are idiopathic; the reported associated disorders are SLE or<br />

Lymphoma. We report an interesting case in a patient who developed mixed AIHA after recent chronic<br />

rejection <strong>of</strong> a transplanted kidney and withdrawal <strong>of</strong> immunosuppressant medications.<br />

CASE PRESENTATION: A-72-year -old Caucasian female with a known history <strong>of</strong> end-stage kidney<br />

disease was sent to the hospital by her nephrologist regarding abnormal blood work after hemodialysis.<br />

There was a significant drop <strong>of</strong> her hemoglobin. The patient had her usual hemodialysis treatment two<br />

days before without complications and with a clear hemodialysis filter. When she returned home, she<br />

was much weaker than usual. She did not have any fever, chills, melena or gross hematuria. Upon<br />

presentation, blood pressure was 144/67 mmHg, pulse 80 beats/min, temperature 97.4F, respiratory<br />

rate 18/min, and oxygen saturation was normal. Her physical exam was completely normal. Laboratory<br />

data was significant for low hemoglobin level <strong>of</strong> 4.86 g/dl, Platelet count <strong>of</strong> 311 x 10 9 /l and a WBC <strong>of</strong><br />

11x 10 9 /l. Further evaluation revealed too numerous red blood cells in the urine. Total bilirubin, SGOT<br />

and LDH were elevated, while haptoglobin and complements were abnormally reduced. A direct<br />

antiglobulin test was positive with serological detection <strong>of</strong> cold and warm antibodies, and the patient<br />

was typed as blood group A with positive alloantibodies. Tests to exclude viral, bacterial and connective<br />

tissue diseases were all negative. Treatment with dexamethasone and blood transfusion was adequate<br />

to bring up and stabilize the hemoglobin close to her baseline on the following days and after discharge.<br />

Our patient has a deceased donor kidney transplant in 2004, which lost function two months before this<br />

admission. Diagnostic biopsy showed moderate to severe tubule interstitial nephritis and staining with<br />

IgG, IgM and C3. After rejection hemodialysis was initiated, Prednisone and Mycophenolate m<strong>of</strong>etil<br />

were stopped and Cyclosporin dose was decreased.<br />

DISCUSSION: Mixed-type autoimmune haemolytic anaemia (AIHA) is rare, the etiology could be<br />

idiopathic or secondary to associated clinical conditions. In mixed type AIHA prompt treatment with<br />

steroids is successful, but there are aggressive forms unresponsive to steroids, in these cases underlying<br />

lymphoma should be ruled out, treating the lymphoma can be adequate. There are reported successful<br />

trials <strong>of</strong> using Rituximab in the aggressive forms, otherwise splenectomy is indicated. Diagnosis could be<br />

challenging as the cold agglutinin titre is low in mixed AIHA.<br />

In this case we demonstrate the occurrence <strong>of</strong> mixed AIHA secondary to the patient’s underlying<br />

condition, and the successful treatment by using steroids.<br />

Non-giant cell temporal arteritis as an initial presentation <strong>of</strong> ANCA associated small-vessel vasculitis<br />

Dheeraj Goyal, MD, MPH Supervisors (Coauthors): Vijay K. Mahajan, MD, Thurai Kumaran, MD<br />

INTRODUCTION: Small vessel vasculitis and temporal arteritis are unknown to manifest together. We<br />

report a case in which Myeloperoxidase anti-neutrophil cytoplasmic antibody (MPO-ANCA) associated<br />

small-vessel vasculitis presented as non-granulomatous, non-giant cell bilateral temporal arteritis.<br />

CASE PRESENTATION: A sixty-seven year-old Caucasian female was admitted with painful rash. It was<br />

acute in onset, progressive in nature, and became intensely pruritic with time. On examination, diffuse<br />

maculo-papular rash was noted on both <strong>of</strong> her lower extremities with sparing <strong>of</strong> soles and genital areas.<br />

She denied any ear, nose, throat or chest complaints. The rest <strong>of</strong> her clinical examination was normal.<br />

Serum creatinine was 2.31 mg/dL. Blood Urea Nitrogen (BUN) level was 42 mg/dL. Urinalysis revealed 2+<br />

proteinuria with no eosinophiluria. Erythrocyte Sedimentation Rate (ESR) was 68 mm/hour. Proteinase 3<br />

anti-neutrophil cytoplasmic antibody (PR3-ANCA) level was normal and MPO-ANCA level was 1524<br />

AU/mL (Normal < 100 AU/mL). The rest <strong>of</strong> the autoimmune workup was negative. Cryoglobulin C3 and<br />

C4 levels were normal.<br />

She was recently evaluated for frontal headache, low-grade fever and neck stiffness. The Cerebrospinal<br />

Fluid (CSF) analysis and Magnetic Resonance Imaging (MRI) <strong>of</strong> the brain at that time were unremarkable.<br />

Bilateral temporal artery biopsies revealed focal mural inflammatory infiltrates with disruption <strong>of</strong><br />

internal elastic lamina in the right-sided temporal artery. Interestingly, no giant cells or granulomas were<br />

seen.<br />

Renal biopsy revealed pauci-immune necrotizing glomerulonephritis without full crescent formation.<br />

Small blood vessels in the renal cortex showed vasculitic changes with fibrinoid necrosis. No immune<br />

complex deposition was noted. She was treated with intravenous Methylprednisolone pulse therapy for<br />

three days. Her rash improved, and she was subsequently switched to oral Prednisolone and<br />

Cyclophosphamide. However, her renal function did not show significant improvement. Low dose<br />

Bactrim was started for Pneumocystis jiroveci pneumonia prophylaxis, and she was discharged to an<br />

extended care facility (ECF).<br />

DISCUSSION: Biopsy proven non-granulomatous, non-giant cell bilateral temporal arteritis in a patient<br />

with biopsy proven MPO-ANCA associated small-vessel vasculitis is an extremely rare presentation.<br />

Presence <strong>of</strong> giant cell(s) or granuloma(s) is not necessary to make a diagnosis <strong>of</strong> “temporal arteritis”. The<br />

patient denied any vision changes. However, her age, presence <strong>of</strong> localized headache, elevated ESR<br />

greater than 50 mm/hour, and biopsy proven necrotizing arteritis in her temporal arteries fulfill the<br />

<strong>American</strong> <strong>College</strong> <strong>of</strong> Rheumatology, 1990 criteria for temporal arteritis. Furthermore, renal biopsy<br />

findings strongly favor the presence <strong>of</strong> simultaneous microscopic polyangiitis (MPA).<br />

This case is not only unique, but also challenges the common clinical practice <strong>of</strong> treating vasculitis<br />

merely on the basis <strong>of</strong> size <strong>of</strong> affected vessels. The possibility <strong>of</strong> similar presentation should be kept in<br />

mind while managing vasculitis.<br />

Persistent Fever and A Single Positive Blood Culture: How Far Your Suspension Can Guide You?<br />

Ismail Hader, MD Osama Amro, MD Ahmed Ibrahim, MD Khaldoon Shaheen, MD<br />

INTRODUCTION: Our case emphasizes the importance <strong>of</strong> detection <strong>of</strong> HACEK group infective<br />

endocarditis. Although persistent bacteremia is a major criterion for the diagnosis <strong>of</strong> Infective<br />

Endocarditis, HACEK group organisms lack this feature since they are hard to grow on regular growth<br />

media. A thorough cardiac examination and evaluation with trans-thoracic and esophageal<br />

echocardiogram is a crucial step while initiating empiric antibiotics treatment.<br />

CASE PRESENTATION: A 56 year old male presented with generalized body aches, chills and fever for<br />

eight days. Symptoms were associated with palpitation, sweating, headache, and dry cough. He denied<br />

any IV drug abuse. Physical exam showed tachycardia with irregularly irregular pulse, high grade fever <strong>of</strong><br />

40°C, precordium auscultation revealed normal heart sounds with no murmur. Site <strong>of</strong> pacemaker was<br />

intact with no tenderness or erythema, Lung exam revealed bilateral crackles, Initial blood tests<br />

revealed WBC <strong>of</strong> 12.400 with 22% band and hemoglobin <strong>of</strong> 10.1. ESR was 127. Chest X-ray showed<br />

bilateral multiple pulmonary infiltrates and pleural effusions. Initial management included blood culture<br />

and empirical antibiotics for presumed community acquired pneumonia. On day five, one set <strong>of</strong> blood<br />

culture grew Haemophilous Parainfluenzae. Transthoracic echocardiogram showed no vegetation.<br />

Despite <strong>of</strong> the antibiotics management, he remained febrile with worsening body aches and lethargy. 12<br />

sets <strong>of</strong> repeated blood cultures were negative. TEE was performed and showed large vegetation on the<br />

tricuspid valve. The diagnosis <strong>of</strong> Haemophilous Parainfluenzae infective endocarditis complicated by<br />

pulmonary septic emboli was made. He was treated with intravenous antibiotics for an additional<br />

6 weeks. Physical examination, TEE and surveillance blood cultures were negative at the 3-month<br />

follow-up, and the patient had been well since.<br />

DISCUSSION: Numerous pathogens can cause infective endocarditis (IE), including Haemophilus<br />

parainfluenzae. H. parainfluenzae is part <strong>of</strong> the HACEK group that may cause about 3% <strong>of</strong> the total<br />

endocarditis cases, and is characterized by a subacute course and large vegetations. Infective<br />

endocarditis has multifarious manifestations. Diagnosis can be challenging and its capacity to mimic<br />

other conditions may obscure the outcome in those cases where classic manifestations are not evident.<br />

In our case, we prematurely discounted the diagnosis <strong>of</strong> IE; despite he had no audible murmur and had a<br />

single positive blood culture for HACEK pathogen out <strong>of</strong> fourteen sets, several other findings like<br />

anemia, persistent fever, constitutional symptoms and elevated inflammatory markers, all these guided<br />

us to initiate a workup for infective endocarditis . Furthermore, our case emphasizes the relative<br />

insensitivity <strong>of</strong> the transthoracic echocardiogram and the importance <strong>of</strong> the transesophageal<br />

echocardiogram for the diagnosis <strong>of</strong> endocarditis. Likely the presence <strong>of</strong> pacemaker as a foreign body<br />

was only imminent risk factor in this case.<br />

Dysarthria and Ataxia in A 34–Year-Old Woman<br />

Serge Harb, MD Second Author: Ali Ataya, MD Third Author: Terrie-Ann Benjamin MD Fourth Author:<br />

Chadi Alraies MD FACP<br />

INTRODUCTION: A 34-year-old previously healthy woman presented with a one week history <strong>of</strong><br />

dysarthria, verbal stuttering, ataxia and postural instability.<br />

CASE PRESENTATION: She was admitted a week prior to a local hospital with retractabe vomiting and<br />

severe dehydration. She was found to be hyponatremic with a sodium level <strong>of</strong> 110 mmol/L. The rest <strong>of</strong><br />

her laboratory work up results were within normal limits. Initially, she was treated with antiemetics for<br />

her nausea and vomiting and with hypertonic saline for her hyponatremia. However, her serum sodium<br />

levels stayed the same and she was started on Tolvaptan (vasopressin V2 receptor<br />

antagonist). vasssporessin was started on TolvptanOnfOn the subsequent day her serum sodium level<br />

had increased to 145 mmol/L. Later that day, she was discharged in a stable condition. Five days after<br />

discharge, she presented to our hospital with slurred speech, verbal stuttering, dysnomia, neologism,<br />

dysdiadokinesia, and dizziness. On physical exam, she had dysarthria and ataxia with no nystagmus. The<br />

remainder <strong>of</strong> her examination was unremarkable. Her sodium level was normal. A CT scan <strong>of</strong> the brain<br />

was negative for any acute pathology. This was followed by a T2-weighted MRI which showed bilateral<br />

symmetrical hyperintensities in the putamen area and caudate nucleus with sparing <strong>of</strong> globus pallidus<br />

which is consistent with extrapontine myelinosis. She was discharged afte few days <strong>of</strong> physiotherapy<br />

and occupational therapy with mild improvement <strong>of</strong> her neurological sympotms.<br />

DISCUSSION: Rapid correction <strong>of</strong> hyponatremia using Tolvaptan and hypertonic saline (>12 meq/dl in<br />

24 hours) has been associated with extrapontine myeleinosis (EPM). EPM is a variant <strong>of</strong> Osmotic<br />

Demelination Syndrome (ODS). This was formerly referred to as central pontine myelinolysis. However,<br />

since demyelination does not necessarily involve the pons and usually more diffuse, the name has<br />

changed to EPM . Involvement <strong>of</strong> the basal ganglia with sparing <strong>of</strong> the pons is characteristic for EPM,<br />

which has been described in 10% <strong>of</strong> patients with ODS. It can present later (2-6 days) after rapid<br />

correction <strong>of</strong> the serum sodium. In our patient, clinical and MRI features <strong>of</strong> pontine involvement were<br />

absent. Clinically she was dysarthric and ataxic which is attributed to striatal dysfunction. These findings<br />

have been reported in isolated cases <strong>of</strong> EPM. On MRI, extrapontine changes have been described in the<br />

basal ganglia, cerebellum and white matter.<br />

Conclusion: There is no proven effective therapy for EPM.Among patients with hyponatremia, it is<br />

important avoid rapid correction <strong>of</strong> hyponatremia with hypertonic or V2 receptor antagonist<br />

medication. Suggested rate <strong>of</strong> correction is less than 10 meq/L in the first 24 hours and less than 18<br />

meq/L in the first 48 hours.<br />

FACP<br />

INTRODUCTION: CASE PRESENTATION: A 67-year-old man presented to our ER complaining <strong>of</strong> typical<br />

chest pain few minutes after smoking cocaine. Pain was retrosternal and radiating to left shoulder<br />

associated with diaphoresis and nausea but no vomiting. On arrival, his vitals were stable But he was<br />

diaphoretic and in mild distress. His physical exam was unremarkable. Initial EKG in ER showed sinus<br />

tachycardia with no ischemic changes and cardiac markers were normal. He received benzodiazepine,<br />

sublingual nitroglycerine, aspirin, calcium channel blocker, and oxygen. Despite <strong>of</strong> all actions taken,<br />

chest pain persisted. Repeated EKG revealed new left bundle branch block (LBBB). En route to left heart<br />

catheterization (LHC), patient reported resolution <strong>of</strong> chest pain. EKG was repeated in cath lab and<br />

showed resolution <strong>of</strong> LBBB. LHC was cancelled and he was admitted to hospital. Nuclear stress test and<br />

2D echo were normal. He was discharged after being pain free. 8 months later he was admitted with<br />

similar presenation.LHC was done and showed normal coronaries.<br />

DISCUSSION: Cocaine-associated chest pain (CACP) is associated with 250,000 annual ER visits in the<br />

United States. The potential <strong>of</strong> cocaine to induce myocardial ischemia and coronary spasm has been<br />

demonstrated both in vitro and in vivo. Surge <strong>of</strong> catecholamines, thrombosis and platelets activation<br />

have been suggested as a mechanism for ischemia which likely has caused the LBBB in our patient.<br />

Mechanisms <strong>of</strong> Intermittent LBBB include rate dependent block which usually occurs in diseased or<br />

ischemic His-purkinge system. Other mechanisms include phase 3 block which is physiological and occur<br />

in normal individual. Also, cocaine has been shown to have an immediate blocking effect <strong>of</strong> cardiac<br />

sodium channels. Aspirin, benzodiazepines, nitroglycerin and calcium channel blockers should be<br />

included in the treatment for patients presenting with CACP. The current ACC/AHA guidelines<br />

recommend immediate cardiac angiography for patients who presenting with chest pain and new LBBB<br />

after cocaine use. However, almost half <strong>of</strong> CACP patients have normal coronary angiograms.<br />

Furthermore, LHC in the setting <strong>of</strong> cocaine abuse may lead to further worsening <strong>of</strong> coronary spasm in<br />

some cases and worsening <strong>of</strong> myocardial ischemia. We are reporting a case <strong>of</strong> a patient who presented<br />

with CACP and transient new LBBB that resolved with conventional treatment. Similar to our case, most<br />

low risk patients with CACP do well with a low incidence <strong>of</strong> cardiovascular complications. CONCLUSION:<br />

Cocaine can be associated with intermittent LBBB which is likely due to transient ischemia. Risk<br />

stratification and frequent evaluation <strong>of</strong> patient with CACP help avoiding unnecessary and potentially<br />

harmful procedures. The best long term management <strong>of</strong> CACP is cocaine cessation.<br />

Rare Case <strong>of</strong> Pancytopenia<br />

Owais Idris, MD, Associate, St. Vincent Mercy Medical Center, Toledo, OH Mushtaq Ashraf, MD, Uzair<br />

Idris, MSIII, Mohammad Al-Nsour, MD<br />

INTRODUCTION:Pancytopenia is seen commonly in patients with bone marrow infiltration and fibrosis,<br />

and various types <strong>of</strong> myelosuppression, including immune processes and drug reactions. Although iron<br />

deficiency is occasionally seen in patients with pancytopenia, severe iron deficiency directly causing<br />

pancytopenia is rarely seen.<br />

CASE PRESENTATION: A 51-year-old African-<strong>American</strong> female presented with sudden onset<br />

numbness, tingling, and inability to ambulate. Patient had a history <strong>of</strong> asthma, GERD, and hypertension,<br />

but was not on any medications. She complained <strong>of</strong> fatigue, easy bruising, and menorrhagia. Physical<br />

exam was only significant for pale conjunctiva, reduced motor strength in bilateral lower extremities<br />

with right worse than left, and mildly diminished patellar reflexes. Patient’s CBC showed pancytopenia<br />

with a WBC <strong>of</strong> 2.4k/µL, hemoglobin (Hgb) <strong>of</strong> 3.5g/dL, hematocrit (Hct) <strong>of</strong> 12.0%, mean corpuscular<br />

volume (MCV) <strong>of</strong> 63.7fL and platelets (Plt) <strong>of</strong> 48k/µL. Differential showed a decrease in both absolute<br />

lymphocyte count (ALC) and absolute neutrophil count (ANC), 0.70k/µL and 1.22k/µL, respectively.<br />

Other blood work, including basic metabolic pr<strong>of</strong>ile, thyroid function test, liver function test, and<br />

autoimmune workup were normal. CT and MRI <strong>of</strong> the lumbar spine and brain were negative. Ultrasound<br />

<strong>of</strong> the abdomen showed normal spleen, liver, and gallbladder, while pelvic ultrasound pelvis showed an<br />

enlarged uterus with diffuse leiomyomatous involvement. Her anemia workup showed an iron level <strong>of</strong><br />

13µg/dL, total iron-binding capacity <strong>of</strong> 375µg/dL, iron saturation <strong>of</strong> 3%, and ferritin <strong>of</strong> 2µg/L with normal<br />

vitamin B12 and folate levels, while fecal occult blood tests were repeatedly negative. Epstein-Barr virus<br />

and parvovirus antibody panels showed previous exposure with no active infection. A bone marrow<br />

biopsy showed a hypercelluar marrow with 80% cellularity, while iron-stained smear was negative for<br />

iron stores. Patient received emergent packed red blood cell transfusions and was started on IV iron<br />

sucrose. Her symptoms improved significantly, and she was able to ambulate without any assistance.<br />

The cause <strong>of</strong> her severe iron deficiency was found to be menometrorrhagia, and she subsequently<br />

underwent total abdominal hysterectomy. She was discharged on oral ferrous sulfate 325mg three<br />

times a day. Her repeat CBC 3 months later showed her pancytopenia resolved. Her WBC was 6.9k/µL,<br />

Hgb was 13.4g/dL, Hct was 40.5%, MCV was 90.8fL, Plt were 165k/µL, ALC was 1.10k/µL, and ANC was<br />

4.40k/µL.<br />

DISCUSSION: This case illustrates that severe iron deficiency can solely cause pancytopenia in the<br />

general population. In addition to ruling out underlying pathology, such as malignancy, iron deficiency<br />

should be given diagnostic consideration in patients presenting with pancytopenia without any obvious<br />

cause. Evaluation can be easily performed by simple blood testing, and iron replacement therapy can<br />

improve, and even resolve the condition.<br />

INTRODUCTION:Inherited factor VII deficiency is a rare autosomal recessive disorder, which has an<br />

incidence <strong>of</strong> 1 in 500,000 with only about 200 reported cases. It is primarily seen in countries where<br />

consanguineous marriages are common.<br />

CASE PRESENTATION: A 71-year-old Middle Eastern male presented with diffuse abdominal pain,<br />

hematochezia, and generalized weakness. He had a surgical history that included hemorroidectomy,<br />

transuretheral resection <strong>of</strong> the prostrate, cystoscopy with dilatation <strong>of</strong> urethral stricture, inguinal hernia<br />

repair, and dental extractions. There were no complications during these procedures, including<br />

excessive bleeding. He did, however, report spontaneous bilateral shoulder hemarthroses, beginning in<br />

his early 50s. On physical exam, patient had a reducible inguinal hernia, but no purpura. His CBC<br />

revealed hemoglobin (Hgb) was 8.6g/dl with a normal platelet count. Furthermore, he had prothrombin<br />

time (PT) greater than 150 seconds and international normalized ratio (INR) greater than 17.0 with a<br />

normal partial thromboplastin time (PTT). Patient’s past medical records showed his Hgb was 14.8g/dl in<br />

2006. Upon further questioning, patient stated two <strong>of</strong> his five brothers, who live in Lebanon, have a<br />

“bleeding” disorder since childhood and require subcutaneous injections to stop bleeding episodes.<br />

Patient was worked up for coagulopathy. His liver function tests were normal, mixing studies showed no<br />

evidence <strong>of</strong> circulating anticoagulant, and lupus anticoagulant screen was also negative. Based on<br />

laboratory testing and family history, clinical suspicion <strong>of</strong> factor VII deficiency was entertained. Factor VII<br />

activity was measured and was less than 10%, which was confirmed with repeated testing. Records were<br />

obtained from his brothers, which showed both had severe factor VII deficiency with levels less than 2%,<br />

and used recombinant factor VIIa (NovoSeven®) subcutaneous injections on as needed basis. Patient<br />

received 6 units <strong>of</strong> fresh frozen plasma (FFP) and an esophagogastrodudenoscopy was performed that<br />

revealed a duodenal ulcer. Patient’s condition improved with proton-pump inhibitor therapy and he was<br />

discharged without any further bleeding episodes, even though his PT and INR were immeasurably high<br />

after temporary normalization with FFP administration. Patient could not afford Novoseven® and was<br />

advised to visit the nearest ER for any bleeding episodes.<br />

DISCUSSION: This case illustrates striking differences in clinical phenotype, including a late<br />

presentation <strong>of</strong> factor VII deficiency in our patient, who has two brothers with childhood-onset <strong>of</strong> the<br />

same disorder. Compound heterozygosity can explain such variable expression <strong>of</strong> disease, including lateonset<br />

forms. Genotype-phenotype relationships indicate the presence <strong>of</strong> major environmental or<br />

extragenic components modulating expressivity. This case also highlights family history as an integral<br />

part <strong>of</strong> diagnosis, and shows that it can help direct appropriate treatment.<br />

Streptococcus Bovis: A rare etiology <strong>of</strong> epidural abscess<br />

Kalipraveena NV Iruku, MD<br />

INTRODUCTION: INTRODUCTION: Spinal epidural abscess is a rare but fatal condition requiring<br />

immediate diagnosis and intervention. It is commonly seen in the thoracic and lumbar spinal cord<br />

regions in patients with history <strong>of</strong> diabetes mellitus, intravenous drug abuse, alcoholism, epidural<br />

anesthesia, recent surgeries to spinal cord and trauma to the spinal cord along with other comorbidities<br />

like HIV. We want to describe a very rare etiology <strong>of</strong> cervical epidural abscess in an immunecompromised<br />

patient isolating Streptococcus bovis from cultures <strong>of</strong> pus in the abscess.<br />

CASE PRESENTATION: CASE PRESENTATION: A 41 year old African <strong>American</strong> male patient with past<br />

medical history <strong>of</strong> Diabetes and hypertension presented to the ER with complaints <strong>of</strong> bilateral upper<br />

limb numbness followed by weakness from 2 days and neck pain from 2 weeks. The patient was seen at<br />

another hospital for similar complaints in the previous week and was prescribed Percocet for cervical<br />

spasm. There is no history <strong>of</strong> fever except one episode <strong>of</strong> chills. No history <strong>of</strong> intravenous drug abuse,<br />

alcohol intake, recent surgery or trauma to cervical area. The patient was sent for an immediate CT scan<br />

which revealed diffuse subcutaneous edema, when the patient was referred for an emergent MRI which<br />

showed an abscess with cervical cord compression at the level <strong>of</strong> C3 –C4. The patient underwent an<br />

emergent evacuation <strong>of</strong> abscess and C3- C4 partial corpectomy with C3-C4 anterior cervical fusion.<br />

During the surgery, the patient had quadriparesis secondary to spinal shock. The abscess fluid was sent<br />

to culture and sensitivity along with the degenerated disk. The patient was initially treated with<br />

vancomycin, linezolid and zosyn. The culture and sensitivity report isolated heavy growth <strong>of</strong><br />

streptococcus bovis from the abscess without any bacteremia and it was sensitive to ampicillin and<br />

penicillin. The antibiotics were changed according to the culture and sensitivity. The patient recovered<br />

well post operatively and regained power <strong>of</strong> 5/5 in lower limbs and strength <strong>of</strong> 3-4/5 in his upper limbs<br />

3-4 days after surgery. 2D echocardiogram was done which showed no evidence <strong>of</strong> any vegetations.<br />

Colonoscopy was done and was normal without any evidence <strong>of</strong> polyps or masses. The source <strong>of</strong><br />

infection from Streptococcus bovis remains unanswered. The patient was sent to skilled nursing facility<br />

for physical therapy and administration <strong>of</strong> antibiotics.<br />

DISCUSSION: There are only a few case reports <strong>of</strong> brain abscesses or subdural empyema caused by<br />

Streptocccus bovis besides its well acknowledged causation <strong>of</strong> septicemia and endocarditis. In this<br />

patient no associated lesion was detected and the etiology <strong>of</strong> Streptococcus bovis in our patient remains<br />

uncertain. It is very important that our patient is followed up in the future with complete work up for an<br />

occult malignancy including a repeat colonoscopy.<br />

HEMODIALYSIS CURES BLEEDING,ONE MORE REASON TO DIALYZE<br />

Navjot Kaur MD, Vikram Aggarwal MD,Molly Litvin MD,Syed M. Abdi MD,Bikram S.Johar MD.<br />

INTRODUCTION:Anticoagulation for cardiopulmonary bypass (CPB) in patients with Heparin induced<br />

thrombocytopenia can be achieved with direct thrombin inhibitors (DTI) such as bivalirudin.<br />

However,unlike heparin,there is no single reversal drug for DTI, which poses a risk <strong>of</strong> serious bleeding<br />

after CPB. Our case describes a unique approach to successfully deal with such challenging situation.<br />

CASE PRESENTATION: 61 yr male was admitted with worsening dyspnea, syncopal events and lower<br />

limb edema for 1 month. He had past medical history <strong>of</strong> hypertension, Insulin dependent diabetes<br />

mellitus, atrial fibrillation and end stage renal disease, on maintenance hemodialysis for 2 years. On<br />

evaluation,trans-esophageal echocardiography revealed severe aortic stenosis (valve area 0.50 cm2<br />

),aortic insufficiency, moderate tricuspid regurgitation & severe pulmonary hypertension. Cardiac<br />

catheterization revealed normal coronaries with LVEF 45-50%. He was diagnosed to have HIT during<br />

hospitalization. Thrombocytopenia recovered on withholding Heparin.<br />

He underwent Cardiopulmonary bypass for aortic valve replacement with St. Jude valve and tricuspid<br />

valve annuloplasty. Bivalirudin was used during surgery in view <strong>of</strong> recent diagnosis <strong>of</strong> HIT. His baseline<br />

kaolin activated clotting time (ACT) was 116 s. After initial bolus <strong>of</strong> 0.75 mg/kg <strong>of</strong> Bivalirudin,continuous<br />

infusion <strong>of</strong> 0.25 mg/kg/h <strong>of</strong> Bivalirudin was started with goal ACT > 300 s as per the protocol for dialysis<br />

patients. He received 4 intermittent boluses <strong>of</strong> 0.5 mg/kg <strong>of</strong> Bivalirudin. Estimated blood loss was 5000<br />

ml and patient was transfused 2500 ml <strong>of</strong> PRBC. Post-operative course was complicated by persistent<br />

refractory bleeding from incision sites and chest tube drains. Disseminated intravascular coagulation<br />

workup was negative.He received multiple FFPs, platelets, PRBCs, cryoprecipitates and even<br />

recombinant factor 7 .In view <strong>of</strong> his uncontrolled bleeding, hemodialysis using High-flux polysulfone<br />

dialyzer was instituted emergently 5 hours postoperative in order to remove bivalirudin.There was no<br />

other indication for emergency hemodialysis. ACT dropped from 439s to 180s within 3 hours <strong>of</strong> dialysis.<br />

Hemodialysis was stopped once bleeding stopped and chest tube output ceased. Hemostasis was<br />

adequate and the patient was discharged on post-operative Day 13 after an uneventful recovery<br />

without clinical evidence <strong>of</strong> thrombotic complication<br />

DISCUSSION: Bivalirudin is eliminated via predominantly renal excretion and proteolytic cleavage. Very<br />

<strong>of</strong>ten,patients sustain acute kidney injury during CPB, and in such situations, elimination <strong>of</strong> drugs such<br />

as bivalirudin decreases and can lead to severe bleeding complications. Hemodialysis with high-flux<br />

filter eliminates 45-69% <strong>of</strong> bivalirudin. This case is unusual as it emphasizes the significance <strong>of</strong><br />

understanding the pharmacokinetics <strong>of</strong> drugs with narrow therapeutic index <strong>of</strong> safety. Hemodialysis is<br />

an important modality which can be utilized to control bivalirudin induced bleeding in such life<br />

threatening situations.<br />

Beryllium, The New Dust In The Wind.<br />

Maroun Matta, MD, UHCMC ; Fadi Seif, MD, UHCMC ; Hugo Montenegro, MD, UHCMC<br />

INTRODUCTION: In 2004, Henneberger estimated the number <strong>of</strong> workers in industries with airborne<br />

beryllium exposure throughout the United States to 134 000. Beryllium is used not only in spacecraft<br />

and electronics, but in a wide range <strong>of</strong> products that include bicycle frames, golf clubs, computers,<br />

jewelry, and dental alloys. Currently, there is serious concern that the current exposure limit<br />

established by OSHA is failing to protect workers from beryllium sensitization and chronic beryllium<br />

disease (CBD).<br />

CASE PRESENTATION: 60-year-old Caucasian female was admitted for a 2-week history <strong>of</strong> dyspnea on<br />

exertion and a persistent dry cough. She denied fever, chills, night sweats, weight loss, orthopnea, and<br />

lower extremity edema. Her past medical history was notable for a diagnosis <strong>of</strong> sarcoidosis since the age<br />

<strong>of</strong> 20. She was treated with prednisone on multiple occasions. On examination, the patient’s vital signs<br />

were within normal limits. Her oxygen saturation was 91% on room air. Lung exam showed bilateral<br />

inspiratory and expiratory wheezing with poor air entry. Her CBC and blood chemistry, were normal.<br />

Chest X-ray showed diffuse interstitial infiltrates, more pronounced in the upper lobes with bilateral<br />

calcified lymph nodes. A high resolution chest CT showed a diffuse reticulonodular pattern with multiple<br />

hilar subcentimetric nodules with calcification. Pulmonary-function testing showed a FVC <strong>of</strong> 2.08L, a<br />

FEV1 <strong>of</strong> 1.24L and a ratio <strong>of</strong> FEV1 to FVC <strong>of</strong> 60% with normal lung volumes and a DLCO <strong>of</strong><br />

79%. Fiberoptic bronchoscopy with lung biopsy showed, non caseating granulomatous inflammation,<br />

with no interstitial fibrosis and negative acid fast bacilli, or fungi. On further questioning, the patient<br />

mentioned working for a year in a beryllium lab at the age <strong>of</strong> 16, sifting beryllium dust through a ten<br />

mesh filter to make fine powder. Beryllium lymphocyte proliferation test (BeLPT) in the blood and<br />

bronchoalveolar lavage (BAL) fluid was sent and was positive. The diagnosis <strong>of</strong> chronic beryllium disease<br />

(CBD) was made.<br />

DISCUSSION: CBD shares many clinical and histopathological features with pulmonary sarcoidosis.<br />

Among patients diagnosed with sarcoidosis with confirmed beryllium exposure, as many as 40 percent<br />

may actually have CBD. This case illustrates the value <strong>of</strong> a detailed exposure history and the use <strong>of</strong><br />

BeLPT in blood and BAL fluid to make the right diagnosis in patients who present with chronic dyspnea.<br />

Identifying more patients with CBD may help develop more targeted treatment. Furthermore, BeLPT<br />

can diagnose beryllium sensitization in asymptomatic individuals exposed to beryllium. These individuals<br />

were proven to have a high likelihood <strong>of</strong> developing CBD, and may benefit from removal from exposure,<br />

and close follow up to detect the disease at its earliest stage when treatment is most effective.<br />

A Common Infection With An Unusual Organism Masquerading As A Mycobacterium<br />

Mustafa Musleh, MD Co author: Richard K Groger<br />

INTRODUCTION:We report the first case <strong>of</strong> severe catheter related blood stream infection (CRBSI) with<br />

Tsukamurella species in an immunocompetent patient.<br />

CASE PRESENTATION: An 85-year-old Caucasian female presented to the hospital from a nursing home<br />

complaining <strong>of</strong> generalized weakness and shortness <strong>of</strong> breath. Her past medical history was significant<br />

for coronary artery disease, hypertension, and a recent pulmonary embolism. She had a peripherally<br />

inserted central venous catheter (PICC), placed during a recent hospitalization for acute stroke 20 days<br />

prior to the current admission. The patient was hypotensive and tachycardic and responded to IV fluid<br />

resuscitation. Initial lab studies were unremarkable, and a CT <strong>of</strong> the chest was negative for pneumonia.<br />

Blood cultures showed gram positive bacilli. The patient was started on broad spectrum antibiotics<br />

(doripenem and vancomycin). Microbiology lab subsequently reported rapidly growing mycobacteria.<br />

Consequently, vancomycin was stopped and clarithromycin and moxifloxacin were started. The patient<br />

did not respond to antibiotic treatment and repeat blood culture remained positive until the PICC line<br />

was discontinued on the seventh hospital day. Due to inability to identify the pathogen, isolates were<br />

sent to Focus Diagnostics laboratory for further identification. On the 16th hospital day the lab reported<br />

Tsukamurella species, which was susceptible to all antibiotics tested including clarithromycin and<br />

imipenem. During hospitalization the patient developed severe sepsis and multi-system organ failure.<br />

On the 13th hospital day one blood culture grew Enterococcus faecium, and the patient eventually<br />

expired on the 17th hospital day.<br />

DISCUSSION: Tsukamurella species are strict aerobic gram-positive rods that are weakly acid-fast.<br />

Although Tsukamurella infections are rare in humans, the species is probably under-reported when<br />

commercially available testing is used. Isolates can be easily misidentified as Mycobacteria, Nocardia, or<br />

Corynebacteria. Thirty-five cases reporting human infection with Tsukamurella were reported in the<br />

literature. Fifteen cases were CRBSI, all <strong>of</strong> which occurred in immunocompromised patients with either<br />

malignancies or chronic kidney disease on dialysis with long-term indwelling venous catheters. All<br />

patients were successfully treated with antibiotics and catheter removal. Elimination <strong>of</strong> the catheter was<br />

essential for eradication <strong>of</strong> the infection and a subsequent favorable outcome. Our patient is the first<br />

CRBSI <strong>of</strong> Tsukamurella in a relatively immunocompetent patient. Other than possible<br />

immunosenescence, our patient had no other cause for a compromised immune response. Unlike all<br />

previously reported cases <strong>of</strong> similar infection, this patient had no history <strong>of</strong> malignancies or renal<br />

disease and was not on immunosuppressive medication. While most previously reported cases with<br />

Tsukamurella CRBSI survived after antibiotics and catheter removal, this patient did not. It is true that<br />

infection with Tsukamurella may have not been the only cause for this patient’s death, but the infection<br />

at least contributed to the eventual outcome.<br />

A Chilling Chance To Survive!Therapeutic Hypothermia<br />

Chithra Poongkunran MD,Nihad Boutros MD, Rama Narayanan MD<br />

INTRODUCTION: The use <strong>of</strong> Therapeutic hypothermia [TH] in comatose patients following near hanging<br />

attempts to improve neurological outcome has been reported in few case series.There has been no<br />

conclusive evidence in the literature regarding the benefits <strong>of</strong> TH in these situations. We report two<br />

cases <strong>of</strong> complete neurological recovery with TH in survivors <strong>of</strong> near-hanging attempts.<br />

CASE PRESENTATION:<br />

458<br />

CASE 1<br />

A 55 year old male with no significant medical history was brought to the hospital after he was<br />

found by his spouse hanging from an electrical cord in his garage. The estimated hanging time<br />

was 5 minutes.In the ER, the patient was unresponsive with decerebrate posturing and was<br />

intubated. His CT <strong>of</strong> the head and neck were normal. He was initiated on the hypothermia<br />

protocol at 32 o C. He was sedated with prop<strong>of</strong>ol and cisatracurium was used to control shivering.<br />

He was eventually extubated and the hypothermia protocol was discontinued after 24 hrs.<br />

Patient improved remarkably with no neurological sequelae.<br />

CASE 2<br />

A 57 year old male with a significant history <strong>of</strong> depression and alcohol abuse was admitted to<br />

the hospital after a near-hanging suicidal attempt with a belt in his garage. His estimated<br />

hanging time was 10 minutes. He was unresponsive and had a pulseless electrical activity. CPR<br />

was initiated with return <strong>of</strong> spontaneous circulation in 5 minutes. In the ER, he was intubated<br />

and sedated with prop<strong>of</strong>ol. His CT head was negative but CT neck showed mildly displaced T1<br />

and T2 transverse process fractures. The hypothermia protocol was started but was<br />

discontinued in 12 hours due to severe bradycardia.The patient self extubated the next day and<br />

had complete neurological recovery. He was transferred to psychiatric floor.<br />

DISCUSSION: The induction <strong>of</strong> hypothermia to a target temperature 32 o C to 34ºC for 24 hours has<br />

shown to improve the neurologic outcome <strong>of</strong> patients who remained comatose after cardiac arrest.<br />

Studies suggesting similar benefits <strong>of</strong> TH after near hanging has also been reported but the literature<br />

supporting it is very limited. In a recent study by Lee et al, the neurological outcome in near hanging<br />

patient with cardiac arrest was poor despite TH treatment. A complete neurological recovery was seen<br />

in both our patients with and without cardiac arrest. Though the positive outcomes in our patients is<br />

reassuring,randomized controlled trials for an evidence based approach is much awaited. But in the<br />

absence <strong>of</strong> conclusive evidence, it would be reasonable to consider TH in comatose near hanging<br />

victims.

Exercise-associated Hyponatremia In A Weekend Warrior<br />

William C Schnackel, MD Second Author: Kim Jordan, MD, FACP<br />

INTRODUCTION: Exercise-associated hyponatremia (EAH) can occur in amateur and pr<strong>of</strong>essional<br />

athletes competing in endurance type events. Physiologic complications can be devastating, and include<br />

seizure, coma, and death. The etiology <strong>of</strong> this electrolyte disturbance includes sodium loss through<br />

diaphoresis, consumption <strong>of</strong> hypotonic fluids, and SIADH.<br />

CASE PRESENTATION: A 43 year old male was hospitalized following seizure and cardiopulmonary<br />

arrest which occurred during an extended bicycle race. He denied significant medical history and<br />

medication use. The patient had cycled approximately 25 miles when he experienced muscle cramps<br />

and felt ill. He stopped for fluid hydration when he had a witnessed seizure, lost pulse and experienced<br />

respiratory failure. CPR and intubation occurred in the field and he was transported to an outside<br />

hospital. Rhythm analysis was not recorded. Laboratory studies revealed hyponatremia 113 mEq/L and<br />

hypokalemia 2.6 mEq/L. Normal saline 0.9% infusion was started and patient was transferred to our<br />

hospital. Admission studies included serum sodium 113mEq/L, urine sodium 36, serum osmoles 248,<br />

urine osmoles 519, and CPK <strong>of</strong> 4835 U/L. He was treated with 3% normal saline overnight and provided<br />

supportive therapy. His CPK plateaued at 17,000 U/L, and baseline serum creatinine rose from<br />

0.65mg/dL to 0.95mg/dL. By hospital day 5, the patient was extubated, creatinine level was improving<br />

toward baseline, and serum sodium was normal.<br />

DISCUSSION: The incidence <strong>of</strong> exercise-induced hyponatremia (EIH) varies by athlete demographic,<br />

experience, training, and event. Reports estimate that between 2-7% <strong>of</strong> endurance athletes experience<br />

mild hyponatremia with sodium levels

Defying Occam’s razor – dyspnea as a manifestation <strong>of</strong> renal disease.<br />

Patrice Scipio, MD MPH Second Author: Michael Tuchfarber, MD<br />

INTRODUCTION: Rapidly progressive glomerulonephritis (RPGN) is characterized by a rapid increase in<br />

creatinine over a few days to months. While the histopathological diagnosis <strong>of</strong> RPGN is based on<br />

glomerular crescent identification, the clinical diagnosis is less defined and constitutional symptoms<br />

such as fatigue, anorexia and arthralgias, along with laboratory findings <strong>of</strong> hematuria, oliguria, and<br />

proteinuria, may herald the onset <strong>of</strong> RPGN. Despite the non-specificity <strong>of</strong> clinical findings, early<br />

diagnosis and treatment are important to prevent permanent kidney damage and thus death. The case<br />

below describes pauci-immune necrotizing glomerulonephritis- a sub-type <strong>of</strong> rapidly progressive<br />

glomerulonephritis- and a small vessel vasculitis that usually involves anti-neutrophil cytoplasmic<br />

antibodies (ANCA). It emphasizes the ambiguity with which RPGN may present, especially in the face <strong>of</strong><br />

other chronic medical conditions and the need for a high clinical suspicion and aggressive treatment.<br />

CASE PRESENTATION: An 84 year old female with a history <strong>of</strong> diastolic congestive heart failure,<br />

chronic obstructive pulmonary disease, hypertension, coronary artery disease, generalized arthritis and<br />

allergic rhinitis, was admitted to the hospital with a 3-week history <strong>of</strong> progressively worsening<br />

dyspnea. Physical examination was significant for hypertension and bibasilar crackles without<br />

peripheral edema. Chest X-ray was consistent with congestive heart failure (CHF). Echocardiogram<br />

showed a normal left ventricular ejection fraction with impaired diastolic filling. Intravenous lasix and<br />

breathing treatments were administered with minimal resolution <strong>of</strong> the patient’s dyspnea. Incidental<br />

findings <strong>of</strong> normocytic anemia to 9.5, elevated creatinine to 3.3, proteinuria and hematuria pointed to<br />

acute kidney injury as an indirect cause <strong>of</strong> the patient’s CHF. Dicl<strong>of</strong>enac and losartan were discontinued<br />

and per cardiology consult metoprolol and imdur were initiated for blood pressure control. Iron studies<br />

revealed iron deficiency anemia with a reticulocyte index <strong>of</strong> 2.7. Hemoccult testing was negative.<br />

Nephrology was consulted. Spot protein creatinine ratio and ESR were elevated. Haptoglobin was<br />

within normal limits. Workup for multiple myeloma was grossly unremarkable. ANCA testing revealed a<br />

positive myeloperoxidase with a negative proteinase-3. Renal ultrasound demonstrated bilaterally<br />

increased renal echogenicity. Methylprednisolone and cyclophosphamide were initiated with continued<br />

increase in creatinine to 6.1. Renal biopsy was performed and revealed pauci-immune rapidly<br />

progressive glomerulonephritis. Dialysis was additionally initiated for uremia and after one dialysis<br />

session, the patient’s creatinine decreased to 3.8 and she was discharged home with renal follow-up.<br />

DISCUSSION: In this case, the patient’s symptoms <strong>of</strong> dyspnea could have been falsely attributed to<br />

chronic obstructive pulmonary disease or congestive heart failure. A more comprehensive workup with<br />

eventual renal biopsy revealed that pauci-immune necrotizing glomerulonephritis was in fact<br />

contributory to her dyspneic symptoms. Furthermore the patient required aggressive combined<br />

treatment with steroids, cyclophosphamide and hemodialysis.<br />

Prostatic Abscess caused by community acquired Methicillin-resistant Staphylococcus Aureus.<br />

Raja K Singh, MBBS MD, Ashwini Ammunje, MD, Rohit Mahajan,MD, Mushtaq Ashraf MD, Sneha<br />

Koomori MD, Ricardo DeLeon MD.<br />

INTRODUCTION: Community acquired Methicillin-resistant Staphylococcus Aureus (CA-MRSA) has<br />

emerged as a significant pathogen in the recent years. Most MRSA infections are associated either with<br />

hospitalized patients or skin/s<strong>of</strong>t tissue infections. Here we report what we believe to be a rare prostatic<br />

abscess secondary to community acquired MRSA in a healthy diabetic patient.<br />

CASE PRESENTATION: Sixty four year old male with no prior history <strong>of</strong> physician visits or<br />

hospitalization presented with one week duration <strong>of</strong> fatigue, malaise, mild abdominal distention and<br />

urinary retention. He denied history <strong>of</strong> any cardiac, renal, urological or respiratory disorder. He was<br />

diagnosed with new onset diabetes mellitus with glycosylated hemoglobin <strong>of</strong> 14.8 percent. A digital<br />

rectal exam was not performed. Laboratory work up demonstrate white cell count (WBC) <strong>of</strong> 17,000/ cu<br />

mm, prostate specific antigen <strong>of</strong> 8.51ug/L. His urine cultures were positive for more than 100,000 colony<br />

forming units <strong>of</strong> MRSA. Two sets <strong>of</strong> blood cultures were positive for MRSA. He was started on<br />

vancomycin. Computed Tomography (CT) showed pelvic fluid collection along the posterior margins <strong>of</strong><br />

prostate and loculated fluid collections within the prostatic fossa. Eight milliliters <strong>of</strong> purulent pus was<br />

aspirated under CT guided drainage. Cultures from drained pus confirmed MRSA in prostatic abscess.<br />

Subsequent trans-urethral resection <strong>of</strong> prostate and un-ro<strong>of</strong>ing confirmed the diagnosis. His white cell<br />

count continued to decrease and he was discharged home with prolonged course <strong>of</strong> vancomycin.<br />

DISCUSSION: Prostatic abscess with CA-MRSA is a previously healthy individual is a rare phenomenon.<br />

To our knowledge there has been only two previous such case reports in world literature. Our patient<br />

had none <strong>of</strong> the traditional risk factors for MRSA and would be classified by standard criteria as having<br />

CA-MRSA. He did have newly diagnosed diabetes mellitus, which is a risk factor for prostatitis/prostatic<br />

abscess. Our case reinforces the necessity for physicians to be diligent while evaluating and treating a<br />

case <strong>of</strong> suspected prostatitis/prostatic abscess. The primary treatment <strong>of</strong> prostatic abscess should<br />

always be drainage, along with appropriate antibiotics as directed by the cultures <strong>of</strong> the drainage. With<br />

increasing incidence <strong>of</strong> CA-MRSA, clinicians should have a high index <strong>of</strong> suspicion to look for unusual foci<br />

<strong>of</strong> infection such a prostate in previously healthy individuals.<br />

Highly Probable, But Falsely Diagnosed<br />

Brett C Sklaw, MD Second Author: John Davis, MD<br />

INTRODUCTION:Pulmonary embolism (PE) is a disease process that <strong>of</strong>ten appears in the differential<br />

diagnosis <strong>of</strong> patients with respiratory complaints. Unfortunately, it can be a challenging diagnosis to<br />

make as V/Q scans are imprecise and CT pulmonary embolism studies have significant associated risks.<br />

In patients with abnormal renal function, the previously mentioned complexities make this diagnosis<br />

difficult.<br />

CASE PRESENTATION: A 59 year old Senegalese male with a past medical history <strong>of</strong> end-stage renal<br />

disease due to hypertension (formerly on hemodialysis), renal transplant two years prior, and DVT,<br />

presented to another institution with pleuritic chest pain, cough, and dyspnea for one month. Evaluation<br />

at the outside facility revealed acute renal failure and a high probability V/Q scan for PE. He was<br />

transferred to our institution. On arrival, he was not in distress. He was afebrile with stable vital signs,<br />

with an oxygen saturation <strong>of</strong> 97% on room air. His physical examination was remarkable for diminished<br />

breath sounds over the left lung base. He arrived on a heparin drip. His immunosuppressant medications<br />

included sirolimus and cyclosporine. A chest x-ray showed patchy left lung disease and interstitial<br />

changes at the right lung base. A non-contrast chest CT showed bilateral cavitary pulmonary nodules.<br />

He was ruled out for tuberculosis. CT guided biopsy revealed necrotizing granulomatous inflammation,<br />

but no pathogenic organisms. There was no suggestion <strong>of</strong> PE. Wedge biopsy confirmed granulomatous<br />

inflammation, with staining positive for Mycobacterium species. He was started on an anti-tuberculosis<br />

regimen empirically. Following discharge, cultures demonstrated Mycobacterium avium complex (MAC)<br />

and he was switched to an anti-MAC regimen. One month following discharge, he was reportedly doing<br />

well.<br />

DISCUSSION: The diagnosis <strong>of</strong> pulmonary embolism can be challenging in patients with abnormal renal<br />

function because V/Q scans are imperfect and CT PE studies are contraindicated. This case illustrates<br />

that complexity and reinforces the need to maintain a broad differential diagnosis, despite the presence<br />

<strong>of</strong> strongly suggestive diagnostic testing, in order to avoid the error <strong>of</strong> premature closure. This is<br />

particularly important in the immunocompromised host and other vulnerable patient populations.<br />

Without appreciating the limitations <strong>of</strong> a high probability V/Q scan, the diagnosis in this case would<br />

have been missed. Instead, by carrying out appropriately thorough diagnostic evaluation, including an<br />

invasive wedge biopsy, the appropriate diagnosis was made, and mismanagement and further<br />

complications were avoided<br />

RECURRENT ESOPHAGEAL STRICTURES? CONSIDER ESOPHAGEAL LICHEN PLANUS<br />

Ryan Spilman, D.O. Additional Authors: Lisa Mewhort, M.D., Kim Jordan, M.D., FACP, Michael Taxier,<br />

M.D. Riverside Methodist Hospital. Columbus, Ohio.<br />

INTRODUCTION:It is well-known that systemic diseases, including connective tissue disorders and<br />

infectious processes, can involve the esophagus. Esophageal lichen planus (ELP), however, is quite rare<br />

with fewer than 50 previous case reports. Though uncommon, it is important that physicians recognize<br />

the presentation <strong>of</strong> ELP so that proper therapy can be initiated given its association with significant<br />

morbidity.<br />

CASE PRESENTATION: A 60 year old female with a 25 year history <strong>of</strong> persistent dysphagia, despite H2<br />

blocker and proton pump inhibitor therapy, presented for esophageal dilation. She had required annual<br />

esophageal dilation over 20 years for recurrent strictures previously attributed to cervical esophageal<br />

webs. Prior pathology was negative for significant abnormalities, including absence <strong>of</strong> eosinophilic<br />

esophagitis. In 2009, she developed new oral lesions <strong>of</strong> the buccal mucosa and biopsy was consistent<br />

with oral lichen planus. She later developed characteristic lesions on the dorsal surface <strong>of</strong> both hands;<br />

both oral and cutaneous lesions improved with topical steroid therapy. Subsequent EGD revealed a<br />

benign-appearing, severe stenosis in the upper third <strong>of</strong> the esophagus which was dilated and biopsied.<br />

Pathologic examination found a lymphocytic infiltrate concentrated at the junction between the lamina<br />

propria and overlying squamous epithelium and vacuolation <strong>of</strong> the squamous keratinocytes, consistent<br />

with lichen planus. Civatte bodies (necrotic keratinocytes) were not noted, and findings <strong>of</strong> eosinophilic<br />

and Barrett’s esophagitis were absent. A diagnosis <strong>of</strong> ELP was made based on pathology, concomitant<br />

oral and skin lesions, and endoscopic findings. Oral fluticasone was started. She required one<br />

subsequent dilation <strong>of</strong> the upper esophageal stricture one month later for recurrent symptoms. At that<br />

time, facial lesions characteristic <strong>of</strong> lichen planus were present. She returned one year later for<br />

surveillance, oral fluticasone had been discontinued, and she had developed a new stricture in the lower<br />

esophagus.<br />

DISCUSSION: Esophageal lichen planus (ELP) is an inflammatory papulosquamous disorder which<br />

primarily affects middle-aged to older women. Most affected patients already have characteristic oral or<br />

genital lesions, but cutaneous lesions are not always present. Patients commonly present with<br />

dysphagia or odynophagia and mid or upper esophageal stricture, with friable mucosa is noted on<br />

endoscopic examination. Pathological examination reveals epithelial detachment, dense lympocytic<br />

infiltrate <strong>of</strong> the epidermis in a band pattern, and anucleated necrotic basal cells (Civatte bodies). Civatte<br />

bodies, when present, are pathognomonic, but are present in only 40% <strong>of</strong> cases. Therapy centers on<br />

topical and systemic immunosuppression. Left untreated, ELP may lead to stricture formation, and longstanding<br />

disease may be associated with squamous cell cancer. Given significant associated morbidity, it<br />

is important that physicians recognize ELP and initiate appropriate therapy.<br />

Hemobilia and Arterioportal Fistula – A Rare Complication <strong>of</strong> Liver Biopsy<br />

Swapna Thota, MD, Gaurav Kistangari, MD, Harris Taylor, MD<br />

INTRODUCTION: Ovarian hyperstimulation syndrome (OHSS) occurs in approximately 25% <strong>of</strong> women<br />

treated with injectable fertility medications. The vast majority <strong>of</strong> patients who develop OHSS will<br />

experience mild, self-limited symptoms which resolve in about a week. Severe symptoms and<br />

complications requiring hospitalization occur in only 1 to 5 percent <strong>of</strong> women. Recognition <strong>of</strong> signs and<br />

symptoms and knowledge <strong>of</strong> pathophysiology <strong>of</strong> this syndrome are important for prompt<br />

implementation <strong>of</strong> correct therapy as severe complications can result in serious morbidity or lifethreatening<br />

disease.<br />

CASE PRESENTATION: A healthy 41 year old female, gravida 1, para 0, underwent fertility treatment<br />

with egg placement approximately one week prior to presentation. She presented to the emergency<br />

department with abdominal distention, decreased urine output and a 15 kg weight increase over one<br />

week. On examination, she was afebrile, with blood pressure 101/74 and heart rate <strong>of</strong> 95. Anasarca with<br />

3+ pitting edema <strong>of</strong> the thighs was noted, but she had no lower leg edema. Abnormal laboratory studies<br />

included a metabolic acidosis and hyponatremia <strong>of</strong> 126. BUN and creatinine were normal. Abdominal<br />

ultrasound revealed large ascites, but no portal vein thrombosis. Grade III OHSS was diagnosed and<br />

treatment initiated, including paracentesis <strong>of</strong> approximately three liters <strong>of</strong> fluid and aggressive<br />

intravenous fluid resuscitation. All symptoms improved and patient was discharged after several days.<br />

At one week followup, the patient had normal urine output, no ascites, and only trace edema <strong>of</strong> lower<br />

extremities. Ultimately, she gave birth to fraternal twins at 33 weeks.<br />

DISCUSSION: OHSS occurs due to marked ovarian enlargement from multiple ovarian cysts and acute<br />

fluid shift out <strong>of</strong> the intravascular space, related to increased vascular permeability in the region<br />

surrounding the ovaries and their vasculature. Risk factors for OHSS include polycystic ovary syndrome,<br />

low body weight, young age, multiple gestation state, and prior history <strong>of</strong> OHSS. Rapidly rising estradiol<br />

level and multiple oocytes on ultrasound are also predictors. This syndrome is classified as Grade I, II, or<br />

III based on symptom severity and cyst size. Though most women experience only abdominal bloating,<br />

mild abdominal pain, or weight gain (Grade I ), severe symptoms can occur including significant rapid<br />

weight gain (more than 10 lbs in less than one week), ascites, renal failure, hypovolemic shock,<br />

hypercoagulability, acute respiratory distress syndrome, and death (Grades II, III). Grade I OHSS is<br />

generally self-limited and conservative care is appropriate; however, patients with moderate to severe<br />

OHSS require hospitalization, aggressive fluid resuscitation, prophylactic heparin and analgesia.<br />

Paracentesis may be necessary to improve venous return and renal perfusion. Surgical intervention may<br />

be needed in extreme cases <strong>of</strong> ovarian torsion, rupture, or hemorrhage.<br />

EPIPLOIC APPENDAGITIS… A DIVERTICULAR DELUSION<br />

Azadeh To<strong>of</strong>aninejad, DO (Associate), Carl Ortman, MD (Associate), Kim Jordan, MD (Fellow)<br />

INTRODUCTION: Epiploic appendagitis (EA) is an uncommon cause <strong>of</strong> acute abdomen in otherwise<br />

healthy patients with mild or absent secondary signs <strong>of</strong> abdominal pathology. EA is frequently<br />

misdiagnosed as either appendicitis or diverticulitis, which may lead to unnecessary hospitalization,<br />

antibiotics or surgery. We report clinical and radiologic characteristics <strong>of</strong> two patients that were<br />

diagnosed with EA.<br />

CASE PRESENTATION: CASE 1: A 33 year old male with history <strong>of</strong> nephrolithiasis presented with left<br />

flank pain, exacerbated by eating. He denied fever, nausea, vomiting and diarrhea. Examination revealed<br />

normal vital signs, and slight tenderness in the left lower quadrant (LLQ) without rebound. CBC,<br />

chemistries and urinalysis were normal. Abdominal and pelvic CT was initially reported as diverticulitis <strong>of</strong><br />

distal descending colon and cipr<strong>of</strong>loxacin and metronidazole were started. However, given patient’s lack<br />

<strong>of</strong> fever, absence <strong>of</strong> leukocytosis, and his clinical presentation, the team asked for film review. A second<br />

radiologist noted ovioid fat densities on CT characteristic <strong>of</strong> epiploic appendagitis. Antibiotics were<br />

stopped, the patient was treated with pain medications, monitored overnight and discharged to home in<br />

stable condition.<br />

CASE 2: A healthy 26 year old male was admitted with four days <strong>of</strong> progressive stabbing LLQ pain. He<br />

denied fever, and had been eating well with normal bowel movements. Physical examination revealed<br />

normal temperature, blood pressure 140/103, pulse 100, and mild tenderness to palpation at LLQ. CBC,<br />

chemistries, and urinalysis were normal. CT <strong>of</strong> the pelvis/abdomen was interpreted as acute<br />

inflammatory changes at the junction <strong>of</strong> the descending and sigmoid colon consistent with acute<br />

diverticulitis. However, given no clinical findings for acute diverticulitis, radiologist reviewed the images,<br />

when he noted characteristic oval shaped areas <strong>of</strong> fat with surrounding inflammatory changes,<br />

consistent with epiploic appendagitis. Patient was discharged to home on pain medications and was<br />

instructed to follow up with PCP in one week.<br />

DISCUSSION: Appendageal epiploicae are normal, fat-filled out-pouchings <strong>of</strong> peritoneum arising from<br />

the serosal surface <strong>of</strong> the colon. EA is a benign, self-limiting cause <strong>of</strong> abdominal pain, more frequently<br />

seen between the second and fifth decades <strong>of</strong> life, and induced by either appendageal torsion or<br />

spontaneous venous thrombosis <strong>of</strong> an appendageal draining vein. In the past, EA was a diagnosis <strong>of</strong><br />

exclusion and was only confirmed after surgery. However, with improved imaging techniques, surgery<br />

may be prevented. CT findings are virtually pathognomonic, revealing a 2-5 cm, oval-shaped, fat density,<br />

paracolic mass with thickened peritoneal lining and surrounding fat stranding. When patients present<br />

with localized lower abdominal pain and lack associated symptoms or laboratory abnormalities, epiploic<br />

appendagitis should be highly suspected. Symptoms respond well to anti-inflammatory medications, and<br />

generally last only a week.<br />

Apical Hypertrophic Cardiomyopathy: Common Presentation <strong>of</strong> a Rare Disorder<br />

Bill C Tran, MD Second Author: Bimal Padaliya, MD<br />

INTRODUCTION: Apical hypertrophic cardiomyopathy (AHC), also known as Yamaguchi syndrome, is a<br />

rare, benign subtype <strong>of</strong> hypertrophic cardiomyopathy (HCM) that affects approximately 25% <strong>of</strong> HCM<br />

patients in the Japanese population and approximately 1-2% <strong>of</strong> HCM patients <strong>of</strong> non-Japanese<br />

descent. Classically, asymptomatic patients are identified based on suggestive electrocardiographic<br />

findings that include giant T wave inversions in the anterolateral precordial leads secondary to<br />

repolarization abnormality. Diagnosis is confirmed by surface echocardiography or cardiovascular<br />

magnetic resonance. In patients with typical chest pain presenting with similar ECG findings, initial<br />

diagnostic work-up includes ruling out an acute coronary syndrome (ACS). The current case illustrates a<br />

common presentation <strong>of</strong> a chest pain syndrome identified as a rare diagnosis <strong>of</strong> AHC.<br />

CASE PRESENTATION: A 40-year old Caucasian male without significant past medical history presented<br />

to the emergency department with several hours <strong>of</strong> acute onset substernal crescendo chest discomfort.<br />

The discomfort radiated to his bilateral shoulders and was associated with nausea, flushing, and<br />

lightheadedness. Patient denied any prior history <strong>of</strong> similar chest discomfort and his sole cardiovascular<br />

risk factor included ongoing tobacco abuse. There was no family history <strong>of</strong> premature coronary artery<br />

disease, sudden cardiac death or cardiomyopathy. Physical exam showed normal vital signs, no jugular<br />

venous distention, a displaced apical impulse, a prominent fourth heart sound, clear lung fields and<br />

warm lower extremities with no lower extremity edema. Chest x-ray showed no acute cardiopulmonary<br />

process. ECG demonstrated sinus bradycardia, left ventricular hypertrophy with deep, symmetrical<br />

anterolateral T wave inversions. Laboratories were significant for a mildly elevated troponin-I <strong>of</strong> 0.24<br />

ng/ml (normal < 0.06 ng/ml). Patient was treated for a non-ST elevation myocardial infarction with<br />

aspirin 325mg, clopidogrel 600mg, intravenous heparin, and sublingual nitroglycerin and transferred to<br />

our institution for coronary angiography. Cardiac catheterization revealed angiographically normal<br />

epicardial coronaries with left ventriculogram demonstrating normal wall motion and apical<br />

hypertrophy. Surface echocardiography reaffirmed isolated hypertrophy in the left ventricular apex in<br />

an “ace-<strong>of</strong>-spades” configuration. Patient was diagnosed with AHC and discharged home with<br />

outpatient holter monitoring, follow-up genetic counseling, and recommended screening <strong>of</strong> first-degree<br />

family members.<br />

DISCUSSION: This case illustrates a rare diagnosis <strong>of</strong> AHC in a patient that presented with common<br />

symptoms and findings mimicking ACS. The work-up for chest pain syndromes commonly includes a<br />

broad differential diagnosis where a detailed history, physical exam, and focused noninvasive and<br />

invasive testing can be diagnostic as highlighted by this case. <strong>Physicians</strong> who care for patients with<br />

chest pain syndromes should therefore be aware <strong>of</strong> this rare subtype <strong>of</strong> HCM and the classic findings<br />

associated with it.<br />

PERSONALITY CHANGE IN AN 80 YEAR OLD: AN UNUSUAL CASE<br />

Amy Vizcarra, DO Second Author: Kim Jordan, MD<br />

INTRODUCTION: INTRODUCTION: Elderly patients are <strong>of</strong>ten diagnosed with dementia or delirium<br />

when presenting with confusion, psychomotor agitation, complex paranoid delusions, and impaired<br />

functional ability. These same symptoms also meet the DSMIV criteria for bipolar disorder. Because<br />

initial presentation <strong>of</strong> manic disorder in the geriatric population is uncommon, patients may be misdiagnosed,<br />

leading to inappropriate therapy, substantial morbidity and mortality.<br />

CASE PRESENTATION: An 80-year old female with a family history <strong>of</strong> schizophrenia presented to an<br />

outside hospital with confusion, agitation, slurred rapid speech, and “rambling ideas”. Physical<br />

examination was normal, except for agitation, temporal disorientation, and delusions. Brain CT and MRI<br />

were read as “chronic microvascular ischemic changes” with mild to moderate global<br />

atrophy. Laboratory studies were normal. She was treated with haloperidol and released in 24 hours,<br />

and was “ok initially” per family, except for insomnia and “nonstop talking”. Three months later, she<br />

stalled her car in traffic, demonstrating bizarre behavior, resulting in police escort to the ER. Repeat<br />

head CT was unchanged and evaluation for underlying medical illness was negative. She was admitted to<br />

an inpatient psychiatric ward and diagnosed with bipolar disorder and mania. She improved with<br />

ziprasidone therapy, but was discharged on no psychotropic medications. At follow-up, her primary care<br />

physician started quetiapine for recurrent agitation, but she discontinued because <strong>of</strong> excess sedation.<br />

She was subsequently referred to a geriatrician. Screening memory tests were normal (MMSE 30/30 and<br />

3MS 98/100) but neuropsychological testing suggested mild frontal temporal deficits. Brain PET scan<br />

showed mild decreased uptake in posterior cingulate, caudate, inferior frontal and superior temporal<br />

gyri. TSH was mildly elevated at 6.24, and levothyroxine dosage was adjusted. Further historical review<br />

revealed that she was diagnosed with hypomania and insomnia in 2005, though not treated. A trial <strong>of</strong><br />

valproic acid was initiated and at follow-up, her behaviors had improved and agitation decreased.<br />

DISCUSSION: This case illustrates the challenges <strong>of</strong> recognizing clinical and historical features <strong>of</strong> bipolar<br />

disorder (BD) in the geriatric population. New onset BD is uncommon after 65, with estimated<br />

prevalence rates <strong>of</strong> 0.1-0.4%. In contrast to early BD, late-onset disease seems to be associated with<br />

lower rates <strong>of</strong> familial illness, higher rates <strong>of</strong> medical and neurological comorbidity, and higher rates <strong>of</strong><br />

relapse. Clinically, elderly patients may demonstrate an increased incidence <strong>of</strong> frontal release signs, but<br />

there are no path gnomonic findings. Neuropsychological tests may show diffuse cognitive dysfunction<br />

and neuroimaging studies may reveal white matter hyperintensities, sulcal and ventricular enlargement,<br />

or lateralization abnormalities on PET scan. “Best” treatment remains to be defined, but combination<br />

therapy with an antidepressant, antipsychotic, and/or anti-seizure medication may be used.<br />

Peripartum Cadiomyopathy: How Aggressive Anticoagulation should be to Prevent a Devastating<br />

Stroke?<br />

Zhenchao Wang, MD PhD; Sajid Farooq, MD; Sasan Raeissi, MD; Muhammad Rizwan Afzal, MD;<br />

INTRODUCTION: Peripartum cardiomyopathy (PC) is a rare condition with increased incidence recent<br />

years. The low incidence makes the diagnosis a challenging task. More importantly no sufficient data <strong>of</strong><br />

managing stroke associated with biventricular thrombi (BT), the serious complication <strong>of</strong> PC, makes<br />

further studies for guideline <strong>of</strong> heparin treatment in this particular condition necessary.<br />

CASE PRESENTATION: A 18-year-old African-<strong>American</strong> woman with history <strong>of</strong> childhood asthma<br />

developed cough with white sputum and dyspnea on exertion on 32 weeks <strong>of</strong> pregnancy, which was<br />

managed as pharyngitis in another facility. Two months after delivery on 38 weeks, she coughed up<br />

blood tinged sputum. Echo was ordered this time which showed BT with LVEF 20-25%, she was<br />

diagnosed PC. Weight-based heparin protocol was started with PTT ranging from 49-85 . After one day,<br />

she developed generalized seizures with presentation <strong>of</strong> right hemiparesis two hours later when PTT<br />

was maintain at 57.3. Stroke team was consulted at emergency and CT angiogram was ordered which<br />

showed complete left internal carotid artery blockage with possible embolus or thrombus. tPA was not<br />

initiated and clot retrieval was not successful. She was then given heparin infusion maintaining the PTT<br />

at 78.8±8.8. By day 4 after the aggressive heparin infusion, she has no incidence <strong>of</strong> new stroke with<br />

disappearance <strong>of</strong> thrombi and improved EF 25-30%. Pt was then bridged with warfarin and transferred<br />

to rehabilitation program. Two month after, her EF improved to 35-40%.<br />

DISCUSSION: Peripartum cardiomyopathy with increased incidence in recent years has been reported<br />

associated with increased risk <strong>of</strong> BT, which can lead to devastating stroke. The awareness <strong>of</strong> this<br />

condition is important. Also data are limited about management <strong>of</strong> BT. While weight based heparin<br />

plays the major role in the resolution <strong>of</strong> the thrombi, the aggressiveness <strong>of</strong> heparin infusion remain to<br />

be determined for prevention <strong>of</strong> major stroke. The case report above could be the initiative for further<br />

studies <strong>of</strong> the management <strong>of</strong> BT in PC.<br />

CRYPTOCOCCAL MENINGITIS PRESENTING WITH ISCHEMIC STROKES IN A PREVIOUSLY UNDIAGNOSED<br />

HIV PATIENT.<br />

Muhammad Ahsan Zafar, MD Second Author: Lean Coberly, MD<br />

INTRODUCTION: CASE PRESENTATION: A 44 year old homosexual male presented with unsteady<br />

gait. He had recently lost his job and subsequently joined a rehabilitation program for severe depression<br />

and functional decline. At presentation he lacked insight into his depressed functionality and<br />

neurological deficits which had progressed over the preceding four months. He did report having a<br />

tremor in his hands. On examination he had slow “parkinsonian” speech, masked facies, diffuse muscle<br />

weakness, bradykinesia, generalized hyper-reflexia, ataxic gait and positive bilateral babinski reflexes.<br />

There was no past or family history <strong>of</strong> strokes or other neurological pathologies. Head imaging showed<br />

remote bilateral lacunar infarcts in the basal ganglia with two additional small foci <strong>of</strong> acute strokes in<br />

the right basal ganglia. Traditional stroke workup was negative. A lumbar puncture revealed low glucose,<br />

high proteins, high white count and numerous encapsulated yeasts. The CSF cryptococcal culture was<br />

positive and the antigen level was elevated to 1:1,024. He was subsequently tested positive for HIV with<br />

a CD4 cell count <strong>of</strong> 48/uL. Treatment was initiated with Ampohotericin and 5-Flurouracil followed by<br />

Fluconazole. Six weeks after treatment the repeat CSF cultures were negative. Anti-retroviral therapy<br />

(ART) was initiated after eight weeks. His functional deterioration had ceased, but the neurological<br />

deficits persisted.<br />

DISCUSSION: Ten to twenty percent <strong>of</strong> symptomatic HIV patients have neurological dysfunction,<br />

though the prevalence <strong>of</strong> ischemic strokes is extremely low (

Pulmonary arterial hypertension: A clot in question.<br />

Bhavin C Patel, MD* Other Authors: Aneesh Pakala MD*; Hany Magharyous MD**; Brent Brown MD†<br />

*Department <strong>of</strong> Internal Medicine, † Section <strong>of</strong> Pulmonary and Critical Care, ** Department <strong>of</strong><br />

Pathology,<br />

INTRODUCTION: Pulmonary Arterial Hypertension consists <strong>of</strong> a group <strong>of</strong> disorders characterized by<br />

progressive increase in pulmonary vascular resistance leading to right heart failure and premature<br />

death. Idiopathic pulmonary arterial hypertension (IPAH) is a diagnosis <strong>of</strong> exclusion, commonly<br />

manifests as a progressive decrease in exercise tolerance and increasing dyspnea on exertion and carries<br />

poor prognosis without treatment.<br />

CASE PRESENTATION: A 63-year-old-man presented to the clinic with complaint <strong>of</strong> worsening dyspnea<br />

on exertion (for 12 years) in 1999. Physical examination revealed an elevated jugular venous pressure,<br />

bibasilar crackles, left parasternal heave, loud second heart sound, and bilateral pitting pedal<br />

edema. Echocardiogram showed peak pulmonary arterial pressure (PAP) 77 mm Hg and normal LV<br />

function. PFT showed restrictive pattern and normal diffusion capacity. High resolution CT scan <strong>of</strong> the<br />

chest showed no evidence <strong>of</strong> interstitial lung disease. Heart catheterization showed a mean PAP 49 mm<br />

Hg, peak PAP 77 mm Hg, LV end diastolic pressure 12 mm Hg. Pulmonary angiogram revealed a dilated<br />

pulmonary trunk, significant pruning <strong>of</strong> the pulmonary vasculature, and no evidence <strong>of</strong> thrombi.<br />

The patient was diagnosed with Idiopathic Pulmonary Hypertension (IPAH) and started on Epoprostenol<br />

with doses escalating every 6-week for the duration <strong>of</strong> his life. Patient was also started on Warfarin,<br />

which was discontinued for last 18 month because <strong>of</strong> recurrent GI bleed. The patient eventually<br />

deteriorated and died after 17 years from initial diagnosis. Autopsy revealed the surprising finding <strong>of</strong><br />

extensive organized intramural thrombi involving the markedly enlarged pulmonary artery, usually seen<br />

in patients with chronic thromboembolic pulmonary hypertension (CTEPH).<br />

DISCUSSION: IPAH is rare disorder and a diagnosis <strong>of</strong> exclusion. In our case CTEPH was initially ruled<br />

out by a pulmonary angiogram, however, on autopsy we were surprised to find extensive central<br />

intramural thrombi generally consistent with a diagnosis <strong>of</strong> CTEPH. He had no clinical evidence <strong>of</strong><br />

Venous Thrombo-embolism in life or at autopsy. Although Small vessel in-situ thrombosis is a wellknown<br />

pathologic finding in IPAH there are very few case reports <strong>of</strong> extensive thrombosis involving<br />

central pulmonary artery in IPAH. We speculate he developed “in-situ” thrombi <strong>of</strong> main pulmonary<br />

arteries, which contributed to worsened right heart failure and death. Patient with IPAH has several<br />

mechanisms favoring thrombosis including decreased level <strong>of</strong> PGI2, Nitric oxide, thombomodulin and<br />

increased level <strong>of</strong> thromboxane A2 and plasminogen activator inhibitor type 1. It is unknown if central<br />

thrombi seen in IPAH are “in-situ” or embolic in origin but previously published case reports and<br />

prothrombotic state in patient with IPAH favors our view. We emphasize importance on anticoagulation<br />

in patient with IPAH and periodic screening with CT or MR angiography to look for central pulmonary<br />

thrombi in patient who can not be anticoagulated. Clinician should keep heightened suspicion for<br />

central thrombi leading to deterioration <strong>of</strong> clinical status in patient with IPAH.<br />

A Puzzling Case <strong>of</strong> Acute Headache<br />

Kate S. Gustafson, MD Alan J. Hunter, MD<br />

INTRODUCTION: CASE PRESENTATION: 27 year old female with past medical history significant for<br />

bipolar disorder, childhood seizure disorder and recent episode <strong>of</strong> thrush presenting with three weeks<br />

<strong>of</strong> severe headache described as sudden in onset, constant, 10/10 throbbing pain associated with<br />

nausea, vomiting, stiff neck, weight loss, photo- and phonophobia. Other history was notable for recent<br />

bat exposure. She was hemodynamically stable at the time <strong>of</strong> admission and physical exam was<br />

significant for the absence <strong>of</strong> meningeal signs and rash as well as a normal neurologic exam. Labs were<br />

normal with exception <strong>of</strong> CSF with 7 WBC and a lymphocytic predominance (91%). MRI was decidedly<br />

abnormal with dural based nodular and rim enhancement in bilateral frontal lobes along the superior<br />

sagital sinus. Initial differential diagnosis included sarcoidosis, tuberculosis, autoimmune related<br />

granuloma, granulomatosis polyangiitis, HIV-related opportunistic infection, fungal infection and<br />

lymphoma. Extensive lab work-up returned primarily negative. With ongoing concern for possible<br />

malignancy, a brain biopsy was performed. Despite the fact that the Steiner stain on the brain tissue was<br />

negative for spirochetes, serum RPR returned at 1:8 and VDRL <strong>of</strong> the CSF was weakly positive. The<br />

diagnosis <strong>of</strong> cerebral syphilitic gummata was confirmed with positive FTA-Ab and 16S ribosomal RNA<br />

PCR that returned positive for T. pallidum in the brain tissue. Of note, the patient reported having a<br />

single male partner with regular condom use. She was started on a continuous infusion <strong>of</strong> penicillin G 18<br />

million units daily and had very rapid resolution <strong>of</strong> clinical symptoms.<br />

DISCUSSION: Syphilis rates have been on the rise for much <strong>of</strong> the past decade, particularly in MSM. It is<br />

an easily treatable disease in the early stages, but as it is known as one <strong>of</strong> the “great masqueraders” it is<br />

a diagnosis that should be considered even if a patient does not seem to be at high risk based on history.<br />

The most direct means <strong>of</strong> identification is dark field microscopy but serologies are much more<br />

commonly used for diagnosis. There are both non-treponemal (i.e., RPR and VDRL) as well as<br />

treponemal (i.e., FTA-Ab) tests. It is important to remember that approximately 30% <strong>of</strong> patients with<br />

primary, latent and tertiary disease will have a negative non-treponemal test and that FTA-Ab remains<br />

positive life-long. Fortunately, syphilis rates in the US declined slightly in 2010 for the first time since<br />

2001<br />

Acute Intermittent Porphyria: Regression Of Hallucinations And Neuropathy With Hemin<br />

Kristina L Bajema, MD and Brinton Clark, MD<br />

INTRODUCTION:Acute intermittent porphyria (AIP) is an inherited metabolic disorder <strong>of</strong> the heme<br />

biosynthetic pathway that is characterized by a deficiency in porphobilinogen deaminase. During acute<br />

attacks, individuals commonly experience symptoms <strong>of</strong> autonomic dysfunction including abdominal<br />

pain, tachycardia, hypertension, and constipation. In some instances, attacks may be characterized by<br />

peripheral neuropathy and encephalopathy. While hemin has been used to treat AIP flares, there are<br />

currently no randomized trials to <strong>of</strong>fer guidance on the benefit <strong>of</strong> this drug for porphyric neuropathy.<br />

CASE PRESENTATION: A 52 year old man presented with episodic hallucinations and motor weakness<br />

with rapid progression over the course <strong>of</strong> one month. On several occasions he experienced notable<br />

confusion ranging from word-finding difficulty to complete disorientation, agitation, and visual<br />

disturbances described as “patterns floating on the wall.” Moreover, he developed marked weakness<br />

that left him unable to walk or lift his arms <strong>of</strong>f the bed. He had a history <strong>of</strong> episodic diffuse abdominal<br />

and musculoskeletal pain. His exam was notable for tachycardia, variable hypertension, cachexia,<br />

dysphonia, and motor weakness most prominent in the proximal upper extremities with 1-2/5 strength<br />

in the bilateral deltoids, wrist extensors and flexors and 2/5 strength in the intrinsic muscles <strong>of</strong> the<br />

hands. Sensation was preserved. Labs were remarkable for elevated random urine porphobilinogen<br />

(PBG) peaking at 321 umol/L (normal range 0-8.8umol/L) and random urine delta-aminolevulinic acid<br />

(ALA) <strong>of</strong> 259 umol/L (normal range 0-35umol/L). The patient was treated with repeated infusions <strong>of</strong><br />

dextrose as well as two four day courses <strong>of</strong> hemin. With initial hemin treatment, the patient’s<br />

encephalopathy and hallucinations resolved within 2-3 days and he demonstrated subtle improvement<br />

in his upper extremity strength over the course <strong>of</strong> weeks. After discharge to a care facility, poor oral<br />

intake resulted in a recurrence <strong>of</strong> his hallucinations and worsening weakness which again improved with<br />

hemin.<br />

DISCUSSION: Case studies have described a pattern <strong>of</strong> elevated urine PBG and ALA levels along with<br />

abnormalities in nerve conduction studies correlating with symptomatic neuropathic attacks in patients<br />

with AIP. Several hypotheses regarding the pathogenesis <strong>of</strong> neurological sequelae have been<br />

proposed. First, heme deficiency leads to impairment <strong>of</strong> mitochondrial electron transport resulting in<br />

neural energy deficits. Furthermore ALA, which can cross blood-nerve and blood-brain barriers, is<br />

directly neurotoxic. In case reports, treatment with repeated hemin infusions has demonstrated gradual<br />

improvement in motor weakness as well as a decline <strong>of</strong> porphyrin precursor levels and normalization <strong>of</strong><br />

electrophysiologic studies.<br />

Fungal coronary embolism: a rare cause <strong>of</strong> STEMI<br />

Christopher A March, MD<br />

INTRODUCTION:Coronary artery embolism is a rare but well-described phenomenon complicating<br />

acute bacterial endocarditis. Invasive fungal infection is becoming more common as a cause <strong>of</strong><br />

endocarditis. Despite increasing prevalence, only one case report <strong>of</strong> fungal coronary embolism<br />

complicating endocarditis could be found on PubMed query. The following is a case <strong>of</strong> this unexpected<br />

complication <strong>of</strong> fungal endocarditis.<br />

CASE PRESENTATION: ER is a 69-year old male with mechanical aortic valve and recent history <strong>of</strong><br />

treated Pseudomonas endocarditis admitted for evaluation after three surveillance blood cultures<br />

revealed Candida parapsilosis infection. He was asymptomatic on admission and a colonoscopy was<br />

planned to evaluate for a possible enteral source <strong>of</strong> fungemia. On hospital day #1, he suffered cardiac<br />

arrest secondary to ventricular fibrillation. A pulse was regained after nineteen minutes <strong>of</strong> ACLS and he<br />

was transferred to the ICU. Electrocardiography showed marked (>10mm) ST segment elevation in the<br />

leads V2-V6; a pre-admission EKG did not show any ST segment abnormalities. The patient rapidly<br />

developed signs <strong>of</strong> cardiogenic shock including hypotension, poor peripheral perfusion and both<br />

significantly elevated CVP (>20 mmHg) and pulmonary capillary wedge pressure (27<br />

mmHg). Echocardiography revealed decreased ejection fraction and akinesis <strong>of</strong> the apical and lateral<br />

segments <strong>of</strong> the left ventricle. Cardiology was consulted and coronary angiography was deferred as fully<br />

normal angiography was obtained within three months <strong>of</strong> the current admission.<br />

The patient’s clinical condition continued to worsen despite dobutamine and ventilatory support. Left<br />

coronary angiography was then obtained and displayed complete occlusion <strong>of</strong> the left anterior<br />

descending (LAD) artery at the origin <strong>of</strong> the first diagonal artery by a mobile, “grape-like” collection <strong>of</strong><br />

emboli. Embolectomy was successful in restoring TIMI III flow to the distal LAD. Shortly after<br />

embolectomy, shock physiology and ventilatory needs improved rapidly and the patient was successfully<br />

extubated and transferred out <strong>of</strong> the ICU. Blood cultures continued to be positive for C. parapsilosis for<br />

five days after embolectomy and antifungal medications were continued. Aortic valve replacement is<br />

planned for definitive management <strong>of</strong> fungal endocarditis after rehabilitation from this acute illness.<br />

DISCUSSION: Coronary embolism is a common complication <strong>of</strong> endocarditis, affecting up to 60% <strong>of</strong><br />

endocarditis cases on autopsy study. As described in this case, embolectomy is successful therapy for<br />

coronary embolism; it specifically avoids the risk <strong>of</strong> prolonged anti-platelet therapy <strong>of</strong> stent placement<br />

in a patient who may need urgent valve surgery. Risk factors for development <strong>of</strong> fungal endocarditis<br />

include prosthetic valves, indwelling catheters and previous episodes <strong>of</strong> endocarditis. Angiography was<br />

initially deferred in this case <strong>of</strong> STEMI due to the presumed lack <strong>of</strong> coronary artery disease from<br />

previous angiography. As the incidence <strong>of</strong> fungal endocarditis increases, so should the vigilance for this<br />

life-threatening complication.<br />

Angioedema: a Life-threatening Presentation <strong>of</strong> Systemic Lupus Erythematosus (SLE)<br />

Jesus A Moreno, MD<br />

INTRODUCTION:<br />

474<br />

INTRODUCTION: The diagnosis <strong>of</strong> SLE, “the great imitator,” is challenged by its varied<br />

presentation and clinical course.<br />

CASE PRESENTATION: A previously healthy 18 year old Iranian man presented to the emergency<br />

department with acute tongue and lip swelling that had rapidly progressed over 1 hour. Due to airway<br />

compromise, he was treated with IV steroids and underwent emergent nasal intubation. The patient’s<br />

family reported night sweats 3 months prior to admission, 1 month <strong>of</strong> fatigue, 2 episodes <strong>of</strong> subjective<br />

fever, and 1 day <strong>of</strong> a mildly pruritic rash on his back. He moved from Iran at age 9 and had no recent<br />

medication or travel exposures. Exam was notable for a markedly edematous purple tongue that<br />

protruded beyond the teeth and no other skin findings. The patient’s angioedema resolved with<br />

steroids and he was extubated. Extensive evaluation for an etiology <strong>of</strong> his pr<strong>of</strong>ound angioedema<br />

revealed a positive ANA, mild normocytic anemia, and ESR 56. Coagulation studies, complement, antidsDNA,<br />

anti-ssDNA, ANCA antibodies, and serum creatinine were normal.<br />

Outpatient follow up with rheumatology and hematology at 6 weeks revealed abnormal mixing<br />

study, positive anticardiolipin antibody IgG, low C4 and C3 levels, and high C1Q at 122%. He was<br />

diagnosed with hypocomplementemic urticarial vasculitis syndrome (HUVS). One year later he<br />

presented with less severe tongue and facial swelling as well as malar rash and pancytopenia;<br />

repeat laboratories revealed a positive anti-dsDNA. He was diagnosed with SLE and treated with<br />

corticosteroids. His clinical course remains complicated with a recent hospital admission for<br />

upper extremity vasculitis after non-adherence with steroid treatment.<br />

DISCUSSION: This is a unique presentation <strong>of</strong> a young male with angioedema as his initial symptom <strong>of</strong><br />

SLE. SLE is a chronic inflammatory condition that affects multiple organ systems with a highly variable<br />

clinical course. Although kinin-related angioedema due to abnormalities in complement is a known<br />

association with SLE, it is a very unusual presenting symptom. Our patient met only 1 (positive ANA) <strong>of</strong><br />

the <strong>American</strong> <strong>College</strong> <strong>of</strong> Rheumatology criteria for diagnosis <strong>of</strong> SLE (i.e. malar rash, discoid rash,<br />

photosensitivity, oral ulcers, arthritis, serositis, specific renal and neurologic disorders, hemolytic<br />

anemia, pancytopenia, anti-dsDNA, antiSm, anti-phosphlipid antibodies or antinuclear antibodies),<br />

whereas a minimum <strong>of</strong> 4 criteria define a clinical case. Underdiagnosis has been a criticism <strong>of</strong> these<br />

criteria, which are more specific (95%) than sensitive (75%). Our case demonstrates the need for<br />

ongoing surveillance <strong>of</strong> new symptoms and repeat laboratory testing in cases <strong>of</strong> undifferentiated<br />

connective tissue disease as typical antibodies and physical findings may not be initially present.

A case report <strong>of</strong> pituitary metastasis in a Breast cancer patient<br />

By: Sara Hanna, MD, Peter Sidarous, MD, Pramil Cheriyath, MD, Leah Cream, MD<br />

INTRODUCTION: Metastasis to the pituitary gland is very rare. Most common tumors that metastasize<br />

to the pituitary are breast and lung cancer. We report a case <strong>of</strong> pituitary metastasis following breast<br />

cancer treatment with symptoms <strong>of</strong> Central Diabetes Insipidus.<br />

CASE PRESENTATION: This is a 53 year old female with a past medical history <strong>of</strong> HER2 positive<br />

hormone negative inflammatory carcinoma <strong>of</strong> the left breast who presented with a 10 day history <strong>of</strong><br />

increased fatigue, thirst and polyuria. Patient was diagnosed with breast cancer two years ago and<br />

received neoadjuvant chemotherapy in the form <strong>of</strong> Docetaxel, Carboplatin and Trastuzumab. She then<br />

underwent bilateral mastectomy which revealed a residual tumor <strong>of</strong> 0.6cm with negative lymph nodes.<br />

Postmastectomy radiation was also completed.<br />

For four months, the patient has been regularly seen by her physicians for multiple different complains<br />

such as anxiety, fatigue, decrease level <strong>of</strong> energy, increase thirst up to 15 glasses <strong>of</strong> water per day, body<br />

aches, trouble in recalling people name and polyuria. Initial labs were within normal limit except for TSH<br />

and free T4 that were in the lower range <strong>of</strong> normal. Patient was referred to endocrinologist who<br />

diagnosed her with Central Diabetes Insipidus. On further investigations, serum cortisol was low<br />

indicating secondary hypoadrenalism and hypothyroidism. Patient was started on Desmopressin,<br />

resulting in great diminution <strong>of</strong> her polyuria and polydipsia. Patient was treated with Hydrocortisone<br />

and Levothyroxine simultaneously. MRI <strong>of</strong> the brain showed a round enhancing mass lesion along the<br />

inferior aspect <strong>of</strong> the infundibulum <strong>of</strong> the pituitary which was concerning for metastasis. Patient was<br />

then referred to a neurosurgeon who removed the tumor through transphenoidal access and the biopsy<br />

indicated metastatic breast cancer.<br />

DISCUSSION: Brain metastases are the most common intracranial neoplasm and occur in about 25% <strong>of</strong><br />

all cancer patients. However, pituitary metastasis is rare accounting to 1 to 3.6% <strong>of</strong> patients with<br />

malignant tumors, most commonly breast cancer. HER-2 positivity is an increasingly recognized risk<br />

factor for the development <strong>of</strong> brain metastases. Only 7% <strong>of</strong> pituitary metastasis is symptomatic, mostly<br />

involving the posterior pituitary. Even subtle symptoms should not be ignored in patients recently<br />

diagnosed with cancer. Due to the rarity <strong>of</strong> this tumor, no study has been done to compare the success<br />

<strong>of</strong> surgery in comparison to radiation or chemotherapy. One should focus on improving quality <strong>of</strong> life<br />

but no survival benefit to any treatment modality has been proven.<br />

Kaposi’s sarcoma<br />

Anna Kaminsky, DO<br />

INTRODUCTION: Kaposi’s sarcoma is a type <strong>of</strong> malignancy that is associated with immunosuppression,<br />

such as HIV/AIDS, or in post-transplant patients, and is rarely seen in non-HIV population. No definitive<br />

cure has been established, and conventional therapies such as chemotherapy and radiation carry high<br />

toxicity risk, especially in elderly population with multiple comorbidities. Use <strong>of</strong> anti-viral medications<br />

such as Valcyte and monitoring HHV 8 titers as a measure <strong>of</strong> response could be a better option in this<br />

population.<br />

CASE PRESENTATION: A 77-year-old female with a history <strong>of</strong> coronary artery disease, myocardial<br />

infarction, hypertension, hyperlipidemia, and diabetes, presented with complaint <strong>of</strong> rash involving<br />

multiple parts <strong>of</strong> her body. Physical exam showed multiple red colored lesions with irregular borders on<br />

anterior right chest wall, right breast, left flank and left lateral trunk. Biopsy was performed and<br />

confirmed diagnosis <strong>of</strong> Kaposi’s sarcoma. Workup revealed that she had negative HIV status. The PCR for<br />

HHV 8 virus was ordered and came back positive with 49651 DNA copies/mL. She was then started on<br />

Valcyte 1 g bid. She had regular <strong>of</strong>fice follow up and had excellent response with flattening and<br />

disappearance <strong>of</strong> the lesions and decreasing adenopathy in chest, axillae and abdomen on a CT scan.<br />

Follow up HHV 8 titers progressively decreased to 300 DNA copies/mL.<br />

DISCUSSION: Traditionally, Kaposi’s sarcoma in non-HIV patient had limited treatment options with<br />

significant side effects.This case illustrates that in elderly population with multiple comorbidities,<br />

treatment with antiviral medications such as Valcyte results in an excellent response with minimal side<br />

effects and prevents or delays more aggressive treatments such as chemotherapy. Monitoring HHV 8<br />

titers was demonstrated to be a good measure <strong>of</strong> response correlating with clinical improvement<br />

A Life Threatening Case <strong>of</strong> Aripiprazole Induced Dysphagia.<br />

Aurangzeb Baber, MD. Second Author: Rizwan Tariq, MD.<br />

INTRODUCTION: Dysphagia is a rare manifestation <strong>of</strong> Extrapyramidal symptoms, seen in patients<br />

taking antipsychotic medication. The mechanism involves spastic paralysis <strong>of</strong> voluntary muscles used in<br />

swallowing. To our knowledge this is the first ever reported case <strong>of</strong> dysphagia experienced in patient on<br />

low dose aripiprazole.<br />

CASE PRESENTATION: A 43 year old female with past medical history <strong>of</strong> depression, anxiety and mitral<br />

valve prolapse, recently started on 1 mg <strong>of</strong> aripiprazole and titrated up to 10 mg to augment her<br />

antidepressant medications, presented to the ER for evaluation <strong>of</strong> progressive dysphagia for the past 2<br />

weeks. Her dysphagia had progressed to a point where she was not able to swallow her own saliva. A<br />

stat upper GI endoscopy performed in the ER for concern <strong>of</strong> foreign body showed no gross abnormality.<br />

She was admitted to general medical floor and made NPO. Psychiatry was consulted as the top<br />

differential diagnoses were conversion disorder and medication side affect. Aripiprazole was held at this<br />

point. Her swallowing function failed to improve over the course <strong>of</strong> next 4 days both subjectively and<br />

through objective evaluation <strong>of</strong> speech pathologist. In the meanwhile she had to be transferred to ICU<br />

for worsening non gap acidosis and hypotension attributed to starvation ketosis. At this point neurology<br />

was consulted and patient was found to have Parkinson like features on neuro exam including mask-like<br />

facies and cogwheel rigidity. She was started on diphenhydramine to treat the dystonic reaction. She<br />

was also started on bicarbonate infusion and nasoenteral tube feeds. Her acidosis resolved and she was<br />

transferred out <strong>of</strong> the ICU. A video barium swallow was done, which showed moderate oral and severe<br />

pharyngeal impairment <strong>of</strong> swallowing function. Over the course <strong>of</strong> next week after being transferred<br />

from ICU to general medical floor she felt that her swallowing function was getting better. A repeat<br />

evaluation was done by speech pathologist showing significant improvement. A repeat video barium<br />

swallow showed improvement from the prior study. She was started on a modified chopped diet and<br />

she tolerated it well. She was discharged home on diphenhydramine, <strong>of</strong>f aripiprazole and on a modified<br />

chopped diet after 2 weeks <strong>of</strong> hospital stay.<br />

DISCUSSION: This case illustrates the possibility <strong>of</strong> extremely rare side effect <strong>of</strong> aripiprazole, clinicians<br />

must be aware <strong>of</strong> the possibility and consider early discontinuation <strong>of</strong> the medication if dysphagia<br />

develops. Patients taking aripiprazole should be educated about the side effect, which should be<br />

reported immediately.<br />

Epstein Barr virus Induced Severe Hepatic Failure.<br />

Aurangzeb Baber, MD. Second Author: Yassir Nawaz, MD.<br />

INTRODUCTION:Epstein Barr virus(EBV) is a DNA virus associated with a benign self limited illness,<br />

infectious mononucleosis. Infection in immunocompromised patients is sometimes severe and can lead<br />

to fulminant hepatic failure. This is a case <strong>of</strong> a young immunocompetent female presenting with EBV<br />

infection leading to severe acute hepatic failure.<br />

CASE PRESENTATION: 18 year old female with past medical history <strong>of</strong> seizures presented to ER for<br />

evaluation <strong>of</strong> fever, dysphagia and rash. She returned from a trip to North Carolina 1 week back and<br />

developed facial swelling, fatigue and fever. She went to her pediatrician who did a rapid strep test<br />

which was negative, and a monospot test which turned out to be positive. She stayed home<br />

continued oral intake and took ibupr<strong>of</strong>en as needed. Her symptoms continued to get worse with<br />

dysphagia, dysphonia, continued fevers, sore throat, lethargy and malaise. In the ER she was<br />

hypotensive, febrile and had a diffuse rash. The rash was erythematous, macular and involved the palms<br />

and soles. She had facial swelling and enlarged necrotic tonsils. Her labs showed elevated white count <strong>of</strong><br />

13.8 with 17% bands and 9% atypical lymphocytes. Her AST and ALT were almost twice the reference<br />

range, bilirubin was 7.5 mg/dl and INR was 2.5. She was started on vancomycin, cefepime and<br />

clindamycin. She was seen by infectious disease consultant next morning and doxycycline was added to<br />

regimen for concern <strong>of</strong> Rocky Mountain spotted fever given recent travel to North Carolina and a rash.<br />

Symptomatically she got better with the antibiotic treatment and IV hydration but her INR continued to<br />

trend up and 24 hours after admission it went from 2.5 to 4.2. Her AST, ALT and bilirubin remained<br />

elevated. Her blood, urine and sputum cultures were negative. Serologies for Hepatitis A, B, C and E<br />

were negative. It was concluded that she has acute liver failure from EBV infection. She was evaluated<br />

by gastroenterology and was transferred to a transplant facility for worsening numbers and concern for<br />

fulminant hepatic failure although she did not have any hepatic encephalopathy at time <strong>of</strong> transfer.<br />

DISCUSSION: A review <strong>of</strong> the literature reveals that EBV hepatitis is self limiting in most <strong>of</strong> the cases.<br />

This case describes the potential <strong>of</strong> severe hepatic dysfunction in EBV infection even in healthy<br />

immunocompetent individuals. Mortality and morbidity could be reduced by anticipating severe<br />

infections, closely following the numbers and referral to transplant center in advance. This case is<br />

unique as the Icteric presentations such as our patient are extremely rare<br />

ACUTE BACTERIAL ENDOCARDITIS <strong>ASSOCIATE</strong>D WITH GENITAL PIERCING<br />

Swapna Reddy Bemalgi, MD Co- Authors: Parul Kaushik , Rizwan Tariq, Manuel Rosenberg ,Joseph<br />

Hassey.<br />

INTRODUCTION: INTRODUCTION: Streptococcus pyogenes is a very rare cause <strong>of</strong> acute infective<br />

endocarditis with only a handful <strong>of</strong> cases reported in the literature. We believe this to be the first case<br />

<strong>of</strong> group A streptococcus bacteremia and endocarditis associated with genital piercing.<br />

CASE PRESENTATION: CASE DESCRIPTION: A 25-year-old man was admitted with fever, dysuria, yellow<br />

penile discharge and left flank pain <strong>of</strong> one-day duration. Patient was seen in the ER ten days ago with<br />

dysuria and penile discharge, when he received one dose <strong>of</strong> IM ceftriaxone and was discharged with<br />

one-week course <strong>of</strong> doxycycline. His symptoms improved but recurred 2 days after he finished<br />

doxycycline. History was significant for an uncomplicated Prince Albert piercing <strong>of</strong> his genitalia done 8<br />

years ago. On admission, patient had a fever <strong>of</strong> 104 º F. Physical-exam revealed left flank tenderness and<br />

a penile ring passing from the inferior aspect <strong>of</strong> glans through the urethra. There was no redness,<br />

swelling or tenderness at the site <strong>of</strong> the ring or urethra. Laboratory results were significant for<br />

leucocytosis with 17 % bands. He was started on IV vancomycin and ceftriaxone. Urine DNA probes for<br />

Chlamydia and Gonococcus were negative and urine culture from 10 days ago grew Streptococcus<br />

pyogenes. Two sets <strong>of</strong> blood culture on admission grew Streptococcus pyogenes and antibiotics were<br />

appropriately de-escalated. Patient removed his penile ring. Despite appropriate antibiotics, he<br />

continued to have temperature spikes with negative cultures. On hospital day 4, he complained <strong>of</strong><br />

painful lesions on palms and was found to have osler nodes on the fingers. On further exam, he was<br />

found to have new subungal splinter hemorrhages, petechiae on his soles and a new diastolic-murmur in<br />

the aortic area. Trans Thoracic Echocardiogram showed moderate sized vegetation on aortic valve<br />

associated with severe aortic regurgitation. Repeat CT-scan <strong>of</strong> abdomen and pelvis with contrast<br />

showed a wedge shaped left renal infarct. On hospital day-8, he underwent aortic-valve replacement<br />

surgery. An intra-operative Trans Esophageal Echocardiogram showed 3mm perforation in the right<br />

coronary leaflet <strong>of</strong> aortic-valve. The pathology <strong>of</strong> resected valve was consistent with infection. Postoperative<br />

course was uneventful and he was discharged with a 4 weeks course <strong>of</strong> penicillin G.<br />

DISCUSSION: DISCUSSION: Beta-hemolytic streptococcus are an uncommon cause <strong>of</strong> endocarditis<br />

with a reported incidence <strong>of</strong> 0-5% in most reviews. Group-A streptococcus is usually the pathogen in<br />

most <strong>of</strong> these cases and it can cause bacteremia, in association with acute pharyngitis, cellulitis ,<br />

necrotizing fasciitis or intravenous drug use ,however it has not been reported with urethritis and<br />

genital piercing. Streptococcus pyogenes are exquisitely sensitive to penicillins and they remain the drug<br />

<strong>of</strong> choice in such infections.<br />

Spontaneous coronary artery dissection presenting as acute ischemic stroke - unusual presentation <strong>of</strong><br />

a rare condition<br />

Monodeep Biswas, MD, Arjinder Sethi, Nimesh Patel, Anil Singh, Stephen J. Voyce<br />

INTRODUCTION:Spontaneous coronary artery dissection (SCAD) is an unusual cause <strong>of</strong> acute coronary<br />

syndrome or sudden cardiac death. SCAD presenting as acute, cardio-embolic ischemic stroke without<br />

cardiac symptoms is extremely rare.<br />

CASE PRESENTATION: A 26 year old Caucasian male presented with sudden onset left-sided weakness<br />

associated with slurring <strong>of</strong> speech and a left facial droop. Past history was significant for an episode <strong>of</strong><br />

deep venous thrombosis occurring about one year ago. Hypercoagulable screen, including protein C and<br />

S levels, factor V Leiden, antithrombin III, homocysteine levels, antiphospholipid and anticardiolipin<br />

antibodies, was negative. The patient appeared in no acute distress. Vital signs showed a heart rate <strong>of</strong><br />

81 and a BP <strong>of</strong> 136/70 mm Hg. Cardiac examination revealed normal heart sounds. Lungs were clear.<br />

Neurologic examination revealed left sided facial weakness with mild motor weakness and diminished<br />

touch and pain sensations on the left side <strong>of</strong> his body. Deep tendon reflexes were brisk and the left<br />

Babinski sign was positive. The admission EKG showed normal sinus rhythm, left anterior fascicular block<br />

and age indeterminate anterior and inferior wall infarcts. Serial troponin I levels, were 0.02, 0.4, 0.31<br />

ng/ml (normal < 0.05 ng/ml, indeterminate 0.06 - 0.5 ng/ml, positive > 0.5 ng/ml). MRI <strong>of</strong> brain<br />

demonstrated a recent cerebral infarction in right middle cerebral artery territory. The patient was given<br />

tissue plasminogen activator for stroke. A transthoracic 2D echocardiogram on admission demonstrated<br />

regional wall motion abnormality over the apical portion <strong>of</strong> interventricular septum associated with an<br />

apical mural thrombus. The ejection fraction was calculated at 46%. Coronary angiography showed a<br />

radiolucent linear defect suggestive <strong>of</strong> an intimal dissection involving the mid to distal segment <strong>of</strong> the<br />

left anterior descending artery with good flow. The patient was maintained on medical management,<br />

including warfarin therapy, aspirin, beta-blocker and statin with outpatient follow-up.<br />

DISCUSSION: SCAD has been reported most commonly in women during the peripartum period. It may<br />

be associated with autoimmune and collagen vascular diseases, Marfan’s syndrome, chest trauma, and<br />

intense physical exercise. No predisposing conditions could be identified in the patient. The pathology <strong>of</strong><br />

SCAD shows a dissection between the media and the adventitia <strong>of</strong> the artery due to cystic medial<br />

necrosis or hemorrhagic disruption <strong>of</strong> the vasa vasorum. The common presentation <strong>of</strong> SCAD is acute<br />

onset <strong>of</strong> severe chest pain associated with autonomic symptoms such as diaphoresis, palpitations and<br />

either hyper or hypotension. Asymptomatic cases are rare. Percutaneous coronary strategies even<br />

surgical revascularization is reasonable in acute cases with proximal dissection and arterial occlusion in<br />

order to restore coronary perfusion and hemodynamic stability.<br />

presents in a patient with multiple risk factors usually with cardiogenic shock. Here we describe two<br />

cases with different modes <strong>of</strong> presentation as well as outcome.<br />

CASE PRESENTATION: Case 1- A 52 year old white male with diabetes mellitus, hypertension,<br />

hyperlipidemia, chronic renal insufficiency with history <strong>of</strong> anterior wall myocardial infarction with<br />

coronary stents came with complaints <strong>of</strong> severe chest pain following an argument with one <strong>of</strong> his family<br />

members. He went into ventricular fibrillation and had to be resuscitated and brought to the ER. He was<br />

unresponsive and paralyzed. The patient was in shock with BP <strong>of</strong> 85/55 and feeble pulses. The EKG<br />

showed sinus bradycardia, left posterior hemiblock and inferoposterior wall myocardial infarction. 2D<br />

echocardiogram showed an ejection fraction <strong>of</strong> 40 %. The lateral and inferolateral wall was severely<br />

hypokinetic. The coronary angiogram showed complete proximal occlusion <strong>of</strong> right coronary and left<br />

circumflex marginal by large thrombus. Drug eluting stents (DES) were placed in these blood vessels. An<br />

intraaortic balloon pump was introduced for hemodynamic support and patient was transferred to ICU.<br />

The patient had hypoxic ischemic encephalopathy and had to be terminally weaned.<br />

Case 2: A 66 year old obese, hypertensive white male came in to the ER with complaints <strong>of</strong> severe<br />

retrosternal chest pain with radiation to the arms and along with diaphoresis and progressively<br />

increasing shortness <strong>of</strong> breath lasting about an hour. BP was 85/60 at presentation. Clinical examination<br />

was unremarkable. EKG showed marked ST segment elevation in all anterior leads consistent with acute<br />

anterior wall myocardial infarction. Troponin I trended to a maximum value <strong>of</strong> 21.65 (positive is > 0.5).<br />

Coronary angiogram showed total occlusion <strong>of</strong> left anterior descending artery after first diagonal and<br />

left circumflex marginal artery with acute thrombus and DES were deployed appropriately with good<br />

flow in the arteries. The patient had an uneventful recovery.<br />

DISCUSSION: Multivessel coronary thrombosis is a rare clinical diagnosis in setting <strong>of</strong> acute coronary<br />

syndrome. Due to occlusion <strong>of</strong> two or more epicardial coronary vessels a larger area <strong>of</strong> myocardium is<br />

at-risk and patients are more likely to present with hemodynamic compromise or with sudden cardiac<br />

death. Previous history <strong>of</strong> myocardial infarction (MI), family history <strong>of</strong> early MI, tobacco use and<br />

presence <strong>of</strong> multiple coronary risk-factors are associated with multi-vessel coronary thrombosis.<br />

Cocaine use or prolonged coronary vasospasm has been thought <strong>of</strong> as a potential cause too.<br />

Hypercoagulable states related to cancer, hyperhomocysteinaemia, essential thrombocytosis, hormone<br />

therapy and HIV infection has been reported as cause <strong>of</strong> multi-vessel coronary artery thrombosis.<br />

Acquired Hemophagocytic Lymphohistiocytosis Secondary to Severe EBV Infection In An Adult With<br />

Common Variable Immune Deficiency: A Description Of A Rare Disease!<br />

Jincy Clement, MD Other Author: Abdulla Damluji MD, MPH, Mike Roberts MD, Matthew Evans MD,<br />

Michael Evans MD, Mike Bayerl MD Departments <strong>of</strong> Medicine, Anesthesia, Pathology and Division <strong>of</strong><br />

Hematology -Oncology.<br />

INTRODUCTION: Hemophagocytic lymphohistiocytosis (HLH) is a rare, aggressive, and potentially lifethreatening<br />

disorder most <strong>of</strong>ten affects infants at birth to 18 months <strong>of</strong> age. We report a case <strong>of</strong> HLH<br />

secondary to severe Epstein Barr Virus (EBV) in an adult with Common Variable Immunodeficiency<br />

(CVID).<br />

CASE PRESENTATION: A 52 year old man with CVID on weekly Intravenous Immunoglobulin therapy<br />

was admitted for persistent fever up to 104 F for three to four weeks. His examination was significant<br />

for splenomegaly. His lab work showed transaminitis, hyperbilirubinemia, and pancytopenia with<br />

atypical lymphocytes. The peripheral blood smear was notable for marked anisocytosis and moderate<br />

poikilocytosis and dominance <strong>of</strong> large and medium granular atypical lymphocytes. Cytometry <strong>of</strong> the<br />

peripheral blood showed predominance <strong>of</strong> aberrant CD2, CD3, CD5 and CD7 (partial dim) + T-cells,<br />

which was interpreted as reactive or neoplastic in nature.<br />

Bronchoalveolar lavage <strong>of</strong> pleural fluid from thoracentesis and nasal biopsy were negative for infection<br />

and neoplasm. Infectious work-up was normal. He continued to have persistent neutropenia, anemia,<br />

thrombocytopenia, and recurrent fevers with no identified infectious etiology. A bone marrow biopsy<br />

was performed and revealed findings significant for hemophagocytosis. In the presence <strong>of</strong> fever,<br />

anemia, thrombocytopenia, splenomegaly, transaminitis; Hemophagocytic Lymphohistiocytosis<br />

diagnosis was made.<br />

Further, our patient met the other diagnostic criteria for HLH including: hypertriglyceridemia (TG: 319<br />

mg/dL) and elevated Ferritin levels (3990 ng/mL ). Given his CVID and large aberrant T cell population,<br />

he was started on immune-suppression with IV solumedrol, Antithymocyte Globulin (ATG) at 40mg/kg<br />

dosed daily for 4 days, and cyclosporine 4mg/kg by mouth twice daily. His EBV titers came<br />

back elevated and his bone marrow stain was highly positive for EBV. Patient had a rough hospital<br />

course with worsening respiratory status. His overall prognosis was very poor and progressed to DIC,<br />

multisystem failure, and subsequently passed away.<br />

<br />

DISCUSSION: Hemophagocytic lymphohistiocytosis is a fatal disease with very limited treatment<br />

options. Most <strong>of</strong> the data on this disease is from children and presentation in adults is very uncommon.<br />

HLH secondary to severe EBV infection with CVID is extremely rare. A diagnosis <strong>of</strong> hemophagocytic<br />

lymphohistiocytosis should be considered in the setting <strong>of</strong> chronic pancytopenia and persistent fevers<br />

with no etiology and this case highlights key clinical features associated with HLH to help prevent late<br />

diagnosis.<br />

Isolated Ventricular Non-Compaction: An Uncommon Cardiomyopathy.<br />

Julian Manuel Diaz Fraga, MD Elizabeth Dohan, DO Gaurav Gulati, MD Anthony Licata, MD FACC.<br />

INTRODUCTION: Isolated Ventricular Non-Compaction (IVNC) has gained prominence as a rare but<br />

important cause <strong>of</strong> heart failure. We report a case <strong>of</strong> this uncommon cardiomyopathy to highlight<br />

diagnosis and management, and review current understanding.<br />

CASE PRESENTATION: A 23 year old female with family history <strong>of</strong> maternal non-ischemic<br />

cardiomyopathy, presented with insidious onset <strong>of</strong> lightheadedness and dyspnea on exertion over the<br />

past three months. She denied chest pain, orthopnea, palpitations, edema or syncope. Her vital signs<br />

were normal and negative for orthostatic changes. Physical exam was unremarkable. EKG demonstrated<br />

sinus rhythm with non-specific lateral ST-T wave changes and prominent voltage. A 48 hour Holter<br />

showed no arrhythmias. Echocardiogram revealed diffuse left ventricular hypokinesis (Ejection Fraction:<br />

45%) and significant trabeculation <strong>of</strong> the left ventricular apex. A stress echocardiogram showed no<br />

evidence <strong>of</strong> ischemia. A complete blood count, basic metabolic panel, iron panel, ANA, ACE levels,<br />

ionized calcium and ceruloplasmin were all within normal limits. The diagnosis <strong>of</strong> IVNC was made. She<br />

was started on carvedilol and low dose aspirin. An ACE inhibitor was not added secondary to her wish<br />

for future pregnancy. Retrospectively, on review <strong>of</strong> her mother’s echocardiogram, findings suggestive <strong>of</strong><br />

IVNC were noted. On further probing, she mentioned a similar history in her maternal grandfather who<br />

had a defibrillator placed many years ago.<br />

DISCUSSION: Initially described in 1984, IVNC is a genetic cardiomyopathy with an estimated<br />

prevalence <strong>of</strong> 0.05% in the general population. It results from a failure <strong>of</strong> the myocardial compaction<br />

process in the fetus, leading to an altered myocardial structure, seen as prominent left ventricular<br />

trabeculations. It can be either sporadic or familial; therefore, screening <strong>of</strong> family members is<br />

recommended. Echocardiography is the diagnostic test <strong>of</strong> choice. Clinical presentation is variable and<br />

includes heart failure, arrhythmias and thromboembolic events. Treatment is directed at arrhythmia and<br />

heart failure management and the prevention <strong>of</strong> embolic events. ICD implantation is indicated for<br />

secondary prevention but its role in primary prevention is controversial. Long term anticoagulation is<br />

recommended in cases complicated by atrial fibrillation, impaired left ventricular function or<br />

intracardiac thrombi. This case highlights the importance <strong>of</strong> early diagnosis and familial screening. The<br />

general internist should be familiar with the indications that warrant prophylactic anticoagulation, ICD<br />

implantation and the use <strong>of</strong> pharmacotherapy to prevent negative remodeling.<br />

Isolated cardiac amyloidosis AL type: a rarity and a treatment dilemma<br />

Zakiya V Douglas, MD Second Author: Madhav Gudi, MD Third Author: Kotresha Neelakantappa, MD<br />

Fourth Author: Komal Patel, MD<br />

INTRODUCTION: Primary amyloidosis (AL) is characterized by light chain deposition and is associated<br />

with plasma cell dyscrasia. We present a patient with isolated cardiac amyloidosis <strong>of</strong> the AL type, which<br />

is rare and whose treatment options are limited and controversial.<br />

CASE PRESENTATION: A 57-year old woman with well-controlled hypertension presented with<br />

gradually worsening anasarca over 8 months and dyspnea on exertion. She had initially noticed<br />

increasing leg edema whose outpatient work-up produced negative results. Physical examination<br />

revealed anasarca, jugular venous distention, decreased breath sounds in the lower lung fields, mild<br />

erythema with weeping <strong>of</strong> the skin in both legs. She did not have macroglossia or hepatosplenomegaly.<br />

Laboratory values were remarkable for low sodium (132mmol/L) and high thyroid-stimulating hormone<br />

(9.2mU/ml), pro-brain naturetic peptide (7861pg/ml) and troponin T (0.111ng/ml). Serum urea nitrogen,<br />

creatinine, and blood count were unremarkable. Twenty-four-hour total protein excretion was<br />

0.32grams. Serum and urine protein electrophoresis showed no monoclonal band.<br />

Electrocardiogram and echocardiogram revealed left ventricular hypertrophy (LVH), ejection fraction <strong>of</strong><br />

55% and increased right ventricular pressures. Computed tomography <strong>of</strong> the chest, abdomen and pelvis<br />

showed diffuse bowel edema, ascites, pleural effusions, but no masses, adenopathy or organomegaly.<br />

Cardiac magnetic resonance imaging (CRI) revealed mild concentric LVH and delayed hyperenhancement<br />

images consistent with amyloid cardiomyopathy.<br />

Right heart catheterization showed mild-to-moderate pulmonary hypertension at 40mmHg. Endocardial<br />

biopsy was consistent with amyloidosis, lambda light chain type or primary amyloidosis. The patient was<br />

treated with diuretics for heart failure symptoms and is currently undergoing evaluation for heart<br />

transplantation.<br />

DISCUSSION: AL is a systemic disease with multi-organ involvement and high mortality. Only 5% <strong>of</strong><br />

patients have isolated cardiac involvement even though the heart is involved in 50% <strong>of</strong><br />

patients. Although the diagnosis <strong>of</strong> amyloidosis can be made on the basis <strong>of</strong> CRI, tissue diagnosis is<br />

recommended to identify the type <strong>of</strong> amyloidosis, which guides the treatment and prognosis. Most<br />

patients present with congestive heart failure (CHF) which is resistant to conventional treatment and is a<br />

poor prognostic factor, with a life expectancy <strong>of</strong> 6 months from the onset <strong>of</strong> CHF.<br />

Heart transplant followed by high-dose melphalan and autologous stem cell transplantation (HDM-<br />

ASCT) has shown promising results, with 1-3 yr survival in selected patients. A recent study <strong>of</strong> 350<br />

patients reported short-term to intermediate survival rates <strong>of</strong> 83%. This was comparable to non-AL<br />

patients with traditional reasons for heart transplant within the same time frame. Our patient satisfies<br />

the exclusion criterion for AL patients by not having clinical evidence <strong>of</strong> extra-cardiac involvement. Early<br />

recognition and treatment <strong>of</strong> this rare situation can improve outcomes today.<br />

Flow cytometry in detecting the coexistence <strong>of</strong> two distinct hematologic malignancies<br />

Donny V Huynh, MD Second Author: Zachariah DeFilipp, MD<br />

INTRODUCTION: Patients with chronic lymphocytic leukemia (CLL) are known to have an increased risk<br />

<strong>of</strong> developing solid tumors. However, secondary hematologic malignancies are rare. The majority <strong>of</strong><br />

reported cases <strong>of</strong> acute myeloid leukemia (AML) in the presence <strong>of</strong> CLL are related to previous<br />

chemotherapeutic treatment. Therefore, the simultaneous appearance <strong>of</strong> these two malignant cell<br />

types in a patient without previous detection is quite exceptional.<br />

CASE PRESENTATION: A 61 year old man with a past medical history <strong>of</strong> recurrent sinusitis presented<br />

with dyspnea, a productive cough, and a low grade fever which had persisted for one month. He was<br />

transferred to our institution after initial outpatient evaluation revealed pancytopenia and peripheral<br />

blasts. Physical examination revealed scattered rhonchi. Neither lymphadenopathy nor<br />

hepatosplenomegaly were noted. Laboratory studies revealed a hemoglobin 7.4 g/dL, a platelet count<br />

49 x 10 3 /mL, and a white blood cell count 2.9 x 10 9 /L with 52% lymphocytes and 40% blasts. Flow<br />

cytometry identified CD45 dim blasts with an immunophenotype <strong>of</strong> CD13, CD33, CD34 and HLA-DR. In<br />

addition, a monoclonal B-cell population with an immunophenotype <strong>of</strong> CD5, CD19, CD20, and CD23 was<br />

unexpectedly detected. Despite <strong>of</strong> the absolute lymphocyte count <strong>of</strong> 1.5 x 10 9 /L, a typical CLL<br />

phenotype population was seen. Results <strong>of</strong> the bone marrow aspirate and biopsy<br />

immunohistochemistry analysis were similar to peripheral blood indicating the simultaneous<br />

appearance <strong>of</strong> CLL and AML.<br />

DISCUSSION: The concomitant diagnosis <strong>of</strong> AML and CLL in a patient without previous hematologic<br />

malignancy illustrates a rare phenomenon. However, the exact nature <strong>of</strong> this patient’s underlying CLL<br />

remains unknown. A diagnosis <strong>of</strong> CLL requires more than 5000 circulating CLL-phenotype cells per cubic<br />

millimeter, while asymptomatic patients with a lesser number <strong>of</strong> these cells are diagnosed as CLLphenotype<br />

monoclonal B-cell lymphocytosis (MBL). It is unclear whether the patient had CLL-type MBL<br />

or an underlying low risk CLL now presenting with cytopenias related to acute leukemia. This case<br />

emphasizes the ability <strong>of</strong> high-sensitivity flow cytometry analysis to detect distinct clonal cell<br />

populations at low levels. Prior to current techniques, this patient would have been informed <strong>of</strong> a single<br />

acute leukemia. He now faces the uncertainty <strong>of</strong> a second underlying malignancy. With continued<br />

advances in technology, the simultaneous presence <strong>of</strong> leukemias and premalignant conditions is an<br />

occurrence we will more frequently encounter in the future.<br />

Weight Gain: A Treatment for Dysautonomia?<br />

Ruchika Kazi, MD Haseeb A Kazi, MD Shamsuddin Shaik, MD Deepakraj Gajanana, MD Bankim Bhatt,<br />

MD<br />

INTRODUCTION:Gastric bypass surgery (GBS) has become common treatment in the management <strong>of</strong><br />

morbid obesity. The relationship between hypertension, diabetes and obesity is well-established. In<br />

most cases, the weight loss after GBS has been associated with significant improvement in diabetes and<br />

blood pressure control, but in some cases it can be associated with dysautonomia and prolong disability.<br />

We report a case <strong>of</strong> severe orthostatic hypotension after rapid weight loss as a result <strong>of</strong> GBS.<br />

CASE PRESENTATION: A 36-year-old woman with past medical history <strong>of</strong> morbid obesity (BMI 44.5),<br />

status-post GBS three years ago, was admitted with near syncope and dizziness for 10 months since<br />

surgery. She lost over 175 pounds after her GBS. She noted severe dizziness improved only in the supine<br />

position and worsening <strong>of</strong> fatigue. On physical examination, she had significant orthostasis without<br />

reflex tachycardia. She also had decreased sensation in the lower extremities with absent patellar<br />

reflexes. The patient had a low am cortisol with an appropriate response to ACTH stimulation. Prolactin<br />

level was elevated (121.2 ng/ml). The rest <strong>of</strong> the work-up including LH, FSH, estradiol, free T4, TSH, T3,<br />

B12, CBC, CMP, SPEP and UPEP was normal. The Autonomic Nervous System test revealed a decrease in<br />

sympathetic tone causing orthostatic hypotension. Echocardiogram and 24 hour Holter monitoring were<br />

normal. A brain MRI showed an empty sella with compressed pituitary. Multiple tilt table tests and<br />

ambulatory EKG’s were unremarkable. Abdominal wall fat biopsy was negative for amyloid. She was<br />

placed on fludrocortisone, salt tablets, and erythropoietin with slow improvement in the dizziness and<br />

blood pressure. After surgery, the patient also developed hypothyroidism, vitamin D deficiency, and iron<br />

deficiency anemia which responded to treatment initially, but after a few months, with repeated<br />

admissions for refractory syncope, it was thought to be secondary to malabsorption. The patient<br />

ultimately underwent reversal <strong>of</strong> GBS. To date, the patient is now one year post-reversal and her<br />

orthostatic hypotension has resolved. Her BMI has increased to 23 and iron studies, vitamin D level and<br />

TSH levels are all within normal limits.<br />

DISCUSSION: Orthostasis following rapid weight loss after GBS has been reported. As the number <strong>of</strong><br />

these surgeries is increasing, physicians must be aware <strong>of</strong> possible cardiovascular and neurologic<br />

complications. Treatment frequently includes volume expansion with fludrocortisone and salt tablets<br />

along with erythropoietin. Resistant to conventional therapy and in the case <strong>of</strong> treatment failure, as in<br />

our patient, one should strongly consider reversal <strong>of</strong> the GBS.<br />

Relentless Diarrhea: Broadening the Differential<br />

Haseeb A Kazi, MD Shamsuddin Shaik, MD<br />

INTRODUCTION:Gastroesophageal reflux disease (GERD) is a common disease <strong>of</strong>ten treated with<br />

proton pump inhibitors (PPI). Lymphocytic colitis, a form <strong>of</strong> microscopic colitis, is a rare entity, which<br />

may be due to certain medications, including proton pump inhibitors or autoimmune disorders.<br />

Symptoms include nausea, abdominal pain, diarrhea, weight loss, and early satiety. We present a case <strong>of</strong><br />

lymphocytic colitis from esomeprazole.<br />

CASE PRESENTATION: A 61 year-old female with a history <strong>of</strong> GERD, hypothyroidism and osteopenia<br />

presented with intermittent nausea, abdominal pain and diarrhea. The diarrhea was bloody and selflimiting,<br />

without any relation to food or sick contacts. There was no history <strong>of</strong> travel, autoimmune<br />

disease, NSAID use, recent antibiotic use or abnormal collagen metabolism, such as Ehler-Danlos<br />

Syndrome. She had been suffering from these symptoms for approximately one year and had been<br />

treated with multiple courses <strong>of</strong> metronidazole for nonspecific colitis, with an eight pound weight loss<br />

over that time period. Home medications included esomeprazole, levothyroxine and vitamin D<br />

supplementation. The esomeprazole was prescribed three years prior after being diagnosed with GERD.<br />

Hypothyroidism was long-standing and well controlled. Upon further workup, she underwent an upper<br />

endoscopy and colonoscopy, which showed mild antral gastritis and nonspecific erythema scattered<br />

throughout the colonic mucosa. Biopsy was negative for malignancy, but was consistent with<br />

lymphocytic colitis. Electrolytes, CBC, rheumatologic work-up and thyroid function tests were within<br />

normal limits. Stool studies were negative. The patient continued treatment with esomeprazole and<br />

completed a course <strong>of</strong> steroids with an improvement in symptoms. Two weeks later, the patient<br />

complained <strong>of</strong> recurrent diarrhea and nausea. She was made NPO and her diet was slowly advanced as<br />

symptoms resolved. At that time, the esomeprazole was discontinued. It was felt that the lymphocytic<br />

colitis was due to esomeprazole as discontinuation resolved symptoms. To date, there has been no<br />

recurrence <strong>of</strong> symptoms.<br />

DISCUSSION: Lymphocytic colitis is not <strong>of</strong>ten at the top <strong>of</strong> the differential for diarrhea. Specifically,<br />

proton pump inhibitors as the cause <strong>of</strong> colitis are uncommon and only a handful <strong>of</strong> case reports exist<br />

regarding various proton pump inhibitors causing lymphocytic colitis. The exact mechanism and timing<br />

<strong>of</strong> this side effect is unknown. Esomeprazole is a commonly prescribed medication for GERD. In patients<br />

who present with chronic diarrhea while on this medication, the clinician should consider lymphocytic<br />

colitis in the differential.<br />

Headache with Hematochezia: A Case <strong>of</strong> Sumatriptan-Induced Ischemic Colitis<br />

Ryan McConnell, MD Rotonya Carr, MD Allen Hwang, MD Frank Scott, MD Gary Wu, MD<br />

INTRODUCTION: Internists frequently treat migraine headaches, which affect 18% <strong>of</strong> women and 6% <strong>of</strong><br />

men. Sumatriptan (Imitrex), a selective serotonin-1 5-hydroxytryptamine (5-HT1) receptor agonist, is<br />

widely used to abort migraines. The mechanism involves selective intracranial arterial constriction,<br />

though sumatriptan has been implicated in adverse extracranial vascular events. Ischemic colitis results<br />

from hypoperfusion and is the most prevalent form <strong>of</strong> gastrointestinal (GI) ischemia. It has been<br />

reported with oral contraceptive (OCP) and non-steroidal anti-inflammatory drug (NSAID)<br />

use. Sumatriptan-induced ischemic colitis is rare, reported in only 13 prior cases. Most patients were<br />

young and lacked vascular risk factors typically associated with ischemic colitis, suggesting that ischemic<br />

colitis may be an under-recognized and underreported complication <strong>of</strong> sumatriptan use.<br />

CASE PRESENTATION: A 37 year-old woman developed acute hematochezia and abdominal pain. She<br />

suffered recent refractory migraine headaches requiring four 50 mg sumatriptan tablets three days prior<br />

to presentation followed by another four tablets plus 440 mg naproxen on the day prior. Within 24<br />

hours <strong>of</strong> last sumatriptan use, she developed crampy abdominal pain and five episodes <strong>of</strong><br />

hematochezia. She denied fever, diarrhea, antibiotic use, and foreign travel. She was a nonsmoker<br />

without vascular disease risk factors, anemia, hypotension, inflammatory bowel disease (IBD), OCP use,<br />

or selective serotonin reuptake inhibitor (SSRI) use. She was afebrile and hemodynamically stable. She<br />

exhibited left lower quadrant tenderness. Bowel sounds were normal. Anoscopy revealed blood<br />

proximal to the pectinate line. Hemoglobin, WBC count, erythrocyte sedimentation rate, and C-reactive<br />

protein were normal. Stool was negative for bacterial pathogens and C. difficile toxin. CT scan revealed<br />

“moderate mural thickening with mild surrounding inflammatory changes involving the distal transverse<br />

and proximal descending colon.” Colonoscopy showed a 20-centimeter splenic flexural region <strong>of</strong><br />

erythematous mucosa with punctate submucosal hemorrhage. Biopsy was negative for pathologic<br />

change. The abnormalities had resolved upon repeat colonoscopy 6 weeks later. The patient began<br />

propranolol for migraine prophylaxis and reports no further GI symptoms for 10 months <strong>of</strong>f<br />

sumatriptan.<br />

DISCUSSION: This is the second-youngest victim and 14 th reported case <strong>of</strong> sumatriptan-induced<br />

ischemic colitis. The association is strengthened by the temporal relationship, large dose, absence <strong>of</strong><br />

IBD and infection, and lack <strong>of</strong> vascular risk factors. Although this patient took large doses, only five <strong>of</strong> 14<br />

reported cases (36%) occurred with sumatriptan dose escalations. A prior case lacked hematochezia<br />

entirely, raising the possibility that numerous cases go undiagnosed in younger, otherwise healthy<br />

patients. The patient’s naproxen use suggests possible synergistic medication effect. Four <strong>of</strong> 14<br />

patients (29%) took SSRIs and another 29% took NSAIDs. A combination sumatriptan/naproxen therapy<br />

(Treximet) is approved for migraines, which may be a safety concern. This case highlights the<br />

importance <strong>of</strong> adverse reaction reporting and may have implications for limiting sumatriptan doses for<br />

migraines.<br />

SMEAR UNFOLDS THE MYSTERY<br />

Bonita A Mohamed, MD Contributing Authors: Harish Raj Seetha Rammohan MD and Ingrid Kohut DO<br />

INTRODUCTION:Gemcitabine-associated thrombotic thrombocytopenic purpura (TTP) is a rare<br />

complication <strong>of</strong> gemcitabine treatment with an incidence ranging from 0.015% to 1.4%. We describe a<br />

case <strong>of</strong> thrombocytopenia refractory to platelet transfusions in the setting <strong>of</strong> recent therapy with<br />

gemcitabine.<br />

CASE PRESENTATION: A 72-year-old Hispanic female with a past medical history <strong>of</strong> metastatic breast<br />

cancer, right pleurodesis, hypertension, and Type II diabetes mellitus presented with dyspnea on<br />

exertion for three days. On admission, patient had CT Thorax with contrast which confirmed bilateral<br />

pulmonary embolism. Patient received chemotherapy with gemcitabine four days prior to admission.<br />

Initial assessment revealed stable hemodynamic parameters, bilateral lower extremity edema with<br />

tenderness and palpable purpura, and decreased breath sounds on right hemithorax.<br />

CBC showed a leukocyte count <strong>of</strong> 1,300 mm 3 , hemoglobin <strong>of</strong> 7.3 g/dL, hematocrit <strong>of</strong> 21.4%, and a<br />

platelet count <strong>of</strong> 16,000 mm 3 . Electrolyte panel was notable for a BUN 28 mg/dL, creatinine 1.24 mg/dL<br />

and CO2 35 mmol/L. Ultrasonography confirmed an occlusive left popliteal and peroneal deep-vein<br />

thrombosis. A 2D echo revealed normal left ventricular ejection fraction and no right ventricular heart<br />

strain. Chest X-ray was equivocal. Clinical impressions at the time were dyspnea secondary to<br />

pulmonary embolism and pancytopenia secondary to chemotherapy.<br />

Patient was placed on a heparin infusion for pulmonary embolism (PE), packed red blood cell and<br />

platelet transfusions were initiated for anemia and thrombocytopenia, respectively. Patient had<br />

continued thrombocytopenia, refractory to multiple platelet transfusions. Heparin-induced<br />

thrombocytopenia panel was negative and coagulation pr<strong>of</strong>ile within normal range. Additional labs<br />

included LDH 238 IU/L, haptoglobin 64 mg/dL, and reticulocyte count 3.2%. Peripheral blood smear<br />

revealed schistocytosis and the working diagnosis was changed to gemcitabine-associated TTP. Heparin<br />

was discontinued and an IVC filter was placed. Plasmapheresis was initiated concurrently with steroid<br />

therapy and the platelet count recovered to greater than 100,000 mm 3 after 11 cycles. At discharge<br />

patient maintained her platelet count and no longer required plasmapheresis.<br />

DISCUSSION: It is important for clinicians to have delicate suspicion <strong>of</strong> TTP in patients with anemia and<br />

thrombocytopenia in the setting <strong>of</strong> gemcitabine use. This case presents a diagnostic challenge as<br />

anemia and thrombocytopenia are common adverse effects <strong>of</strong> gemcitabine. Diagnosis and<br />

management in this case was further complicated by subsequent PE therapy. Refractory<br />

thrombocytopenia and peripheral smear were integral in raising suspicion for TTP, as not all the<br />

common features were exhibited in our patient. Plasmapheresis with steroid therapy proved<br />

fundamental to recovery <strong>of</strong> platelet count. This case sheds light on the role <strong>of</strong> gemcitabine in<br />

microangiopathic processes and the need for further investigations <strong>of</strong> the pathophysiology. Early<br />

diagnosis and initiation <strong>of</strong> therapy proved vital in this case.<br />

Toes to the lungs: Disseminated Osteomyelitis and Pulmonary Mucormycosis in a M5, Acute Myeloid<br />

Leukemic.<br />

Juhi Moon, MD Entezam A. Sahovic, MD<br />

INTRODUCTION: Mucormycosis is an uncommon filamentous fungi known to cause invasive rhinocerebral<br />

disease. Our patient is unique in that he developed breakthrough mucor infection <strong>of</strong> the bone<br />

and lung while on voriconazole, an occurrence rate <strong>of</strong> only 0.5%. Furthermore, without having risk<br />

factors for a point <strong>of</strong> entry such as trauma or burns, our patient developed osteomyelitis and<br />

necrosis. Recent studies revealed deep and extensive muscle or bone disease to occur in only 4.6% <strong>of</strong><br />

the infected.<br />

CASE PRESENTATION: Our patient is a 47-year-old Caucasian male with a history <strong>of</strong> AML, M5 type who<br />

was admitted because <strong>of</strong> an incidental finding <strong>of</strong> leukopenia by his family doctor. Bone marrow biopsy<br />

revealed acute leukemia and he underwent induction chemotherapy withDAE. Fourteen days later,<br />

biopsy revealed no residual leukemia. However, due to persistent neutropenia he completed the<br />

modified Capizzi regimen. Two weeks later, he developed neutropenic fever and empiric cefepime and<br />

daptomycin were started. Despite therapy, fevers continued and voriconazole was added<br />

empirically. The patient then complained <strong>of</strong> left foot pain. His vital signs were 38.4 C, 73 bpm, 18<br />

breath/min, and blood pressure 122/80. Physical exam found the left hallux warm, edematous, dry, and<br />

tender to palpation. Doralis pedis pulse was absent on the left foot, but there was no cyanosis or<br />

ulcerations. Pertinent labwork included hemoglobin 7.9, white blood cell 0.016, platelets 15, creatinine<br />

kinase 20, and uric acid 1.1. In the following days, erythema and edema encompassed the entire left<br />

foot and left leg. Due to the pain, extent, and rapidity <strong>of</strong> disease the patient underwent a left hallux<br />

amputation. Pathological examination <strong>of</strong> the hallux bone revealed extravascular, branching fungal<br />

hyphae, morphologically consistent with mucormycosis. Antifungal therapy was then changed to<br />

amphotericin B and posiconazole. Four days later the patient started to complain <strong>of</strong> acute onset rightsided<br />

chest pain. Lung exam revealed diminished breath sounds. CT chest showed right upper lobe<br />

pneumonia and BAL was negative. Due to the recent discovery <strong>of</strong> mucormycosis in the toe,<br />

cardiothoracic surgery performed a right upper lobe lobectomy. Pathology report revealed many large<br />

blood vessels filled and occluded by fungal hyphae, consistent with mucormycosis. This was<br />

accompanied by a pulmonary infarct and adjacent suppurative inflammation and extensive organizing<br />

pneumonia. Post-operatively the patient was on long-term antifungal treatment and even achieved<br />

complete remission from his leukemia and is now disease free for the past 4 years.<br />

DISCUSSION: As evidenced by pathology reports our patient experience local infiltration and vascular<br />

invasion causing toe necrosis and acute fungal osteomyelitis, which precluded good antifungal<br />

penetration. Furthermore, pulmonary angioinvasion, thrombosis-causing pulmonary infarction, and<br />

abscess formation also compromised antifungal efficacy. A recent study showed decreased mortality for<br />

pulmonary mucor from 55% to 27% with surgical intervention. In addition delayed initiation <strong>of</strong> an<br />

amphotericin-B based regimen has been reported to be associated with doubled mortality at 12<br />

weeks. Consequently, adequate surgical intervention is required for successful treatment <strong>of</strong><br />

mucormycosis in addition to early and prolonged antifungal therapy.<br />

Cocaine Washout Syndrome : A Rare Case Presentation With Refractory Shock<br />

Ji Hyun Rhee, MD V. Sandeep Yadavalli MD, Parit Mekaroonkamol MD, Rene Franco Elizondo MD, K.<br />

Randall Young MD, Adam K. Rowden DO Albert Einstein Medical Center<br />

INTRODUCTION: Cocaine washout syndrome is a rare complication <strong>of</strong> prolonged cocaine use<br />

manifested by brief coma that resolves spontaneously. There are no data on the incidence or exact<br />

pathophysiology <strong>of</strong> this syndrome; only 3 cases have been reported in the literature since the 1990s.<br />

The proposed mechanism is depletion <strong>of</strong> adrenergic neurotransmitters due to prolonged and persistent<br />

stimulation. Here we report an unusually extreme presentation with coma and refractory shock.<br />

CASE PRESENTATION: A 33-year-old African-<strong>American</strong> woman with history <strong>of</strong> chronic cocaine abuse<br />

was brought to the emergency department (ED) unresponsive. The patient was last seen sic “stoned” by<br />

her mother 6 hours prior to arrival. She was given naloxone in the field with no improvement in mental<br />

status. In the ED, vital signs showed hypotension (61/24mmHg), tachycardia (132bpm), hypoxia (90% on<br />

ambient air) and hypothermia (33.9°C) without cold exposure. Physical examination revealed a<br />

comatose patient with Glasgow Coma Scale <strong>of</strong> 3, covered in vomit, with no gag, cough, corneal reflex, no<br />

nystagmus and sluggishly reactive non-dilated pupils. Remaining physical exam findings were<br />

unremarkable. The patient was intubated for airway protection. Chest radiograph and head CT did not<br />

reveal any acute pathologic process while lab results showed acute kidney injury, increased liver<br />

enzymes up to 1000s, leukocytosis, respiratory and anion gap metabolic acidosis with pH 7.08, pCO2<br />

48mmHg, HCO3 12mmol/L and lactate <strong>of</strong> 64mg/dL. Urine toxicological screening was positive for<br />

cocaine, benzodiazepines, opioids and phencyclidine (PCP), while blood analyses were negative for<br />

alcohol, acetaminophen, salicylates and serum osmolar gap. Despite aggressive fluid resuscitation and 4<br />

vasopressor agents at maximal infusion rates, she remained hypotensive and anuric. Stress dose steroids<br />

and antibiotics were empirically started. However, only 8 hours after admission, her gag, cough and<br />

corneal reflexes were back. Her hemodynamic status also dramatically improved and vasopressors were<br />

being successfully weaned. The following day, she was <strong>of</strong>f vasopressors, her mental status returned to<br />

baseline and was ready to resume spontaneous ventilation. As blood cultures and cosyntropin test were<br />

negative, antibiotics and steroids were discontinued. After being extubated on day 2, she admitted to<br />

daily cocaine use for several months, with a binge episode laced with other drugs on the day <strong>of</strong><br />

admission. After psychiatry was consulted and ancillary support was set up, the patient was discharged<br />

home in a stable condition.<br />

DISCUSSION: This case outlines a rare but potentially fatal complication <strong>of</strong> acute cocaine intoxication.<br />

Hypotension and lack <strong>of</strong> nystagmus eliminated PCP intoxication as a cause while tachycardia did not<br />

favor benzodiazepines or other sedative-hypnotics. Cocaine washout syndrome remains a diagnosis <strong>of</strong><br />

exclusion in patients with corroborative history and high clinical suspicion. Patients should be admitted<br />

to the appropriate level <strong>of</strong> monitoring; i.e. intensive care unit. Aggressive fluid resuscitation with<br />

meticulous hemodynamic and ventilatory support is the cornerstone <strong>of</strong> management in cocaine<br />

washout syndrome.<br />

Tamoxifen associated Budd-Chiari syndrome complicated by heparin-induced thrombocytopenia and<br />

thrombosis<br />

Ji Hyun Rhee, MD Maneerat Chayanupatkul MD, Anand Raman Kumar MD, Manjula Balasubramanian<br />

MD, Gabor Varadi MD Albert Einstein Medical Center<br />

INTRODUCTION: Budd-Chiari syndrome (BCS) is a pathophysiologic process that is characterized by<br />

hepatic venous outflow obstruction at any level from hepatic venule to right atrium, regardless <strong>of</strong> the<br />

cause <strong>of</strong> obstruction. Frequently, patients have one or more underlying thrombophilic conditions that<br />

predispose to BCS. Here we report a rare case <strong>of</strong> BCS associated with Tamoxifen use which was later<br />

complicated by heparin-induced thrombocytopenia and venous thrombosis.<br />

CASE PRESENTATION: A 44-year-old female with a past medical history <strong>of</strong> atypical ductal hyperplasia<br />

and lobular carcinoma in situ, who had been on tamoxifen for chemoprevention for 2 years, presented<br />

with diffuse abdominal pain and increased abdominal girth for 1 month. She was an ex-smoker and had<br />

a significant family history <strong>of</strong> ovarian and breast cancer. Review <strong>of</strong> systems and other social and past<br />

medical history were unremarkable. Physical examination revealed abdominal distention with positive<br />

fluid wave, hepatosplenomegaly and pedal edema. The patient had no other stigmata or history <strong>of</strong><br />

chronic liver disease. Laboratory studies apart from mildly increased alkaline phosphatase and low<br />

albumin were normal including blood count. Viral and autoimmune markers were negative. Imaging<br />

studies including hepatic ultrasound with dopplers and a computed tomography (CT) <strong>of</strong> the abdomen<br />

with contrast followed by a liver biopsy showed findings diagnostic <strong>of</strong> BCS. Work-up for hypercoagulable<br />

states revealed an unclassified occult myeloproliferative disorder with a positive JAK-2 V617 mutation in<br />

peripheral blood and bone marrow. Erythropoietin level was normal. Tamoxifen was discontinued and<br />

the patient was treated with intravenous heparin and transjugular intrahepatic portosystemic shunt<br />

(TIPS) for decompression. Subsequently, the patient developed heparin induced thrombocytopenia and<br />

thrombosis (HITT) and TIPS occlusion. This complication led to rescue therapy which entailed TIPS<br />

revision and change in anticoagulant therapy to argatroban. The platelet count increased to normal in 4<br />

days. Follow-up hepatic ultrasound with dopplers showed patent TIPS and the patient was successfully<br />

bridged to Coumadin.<br />

DISCUSSION: This case emphasizes a rare but catastrophic complication <strong>of</strong> BCS with Tamoxifen. To the<br />

best <strong>of</strong> our knowledge, this is the first report <strong>of</strong> Tamoxifen associated hepatic venous thrombosis.<br />

Underlying myeloproliferative condition like JAK-2 mutation is highly prevalent in BCS and needs to be<br />

tested in all patients with BCS. Finally, since patients with BCS are more prone to develop HITT,<br />

anticoagulation and blood count need to be carefully monitored and the possibility <strong>of</strong> HITT emergence<br />

should always be kept in mind.<br />

A New Twist on a Known Side-Effect <strong>of</strong> Piperacillin-tazobactam<br />

Shamsuddin Shaik, MD Haseeb A Kazi, MD Peter T Ender, MD<br />

INTRODUCTION:Piperacillin/tazobactam is a commonly prescribed antibiotic and is generally<br />

considered safe with minimal side effects. Thrombocytopenia is a known side effect, with a reported<br />

onset <strong>of</strong> 11-21 days. We report a case <strong>of</strong> immediate thrombocytopenia after one dose <strong>of</strong><br />

piperacillin/tazobactam.<br />

CASE PRESENTATION: A 47 year-old Hispanic female with a history chronic lung disease and HIV on<br />

stable antiretroviral therapy for >1 year with a CD4 >200 for last 6 months was admitted with one week<br />

<strong>of</strong> fever, chills and productive cough. She had multiple admissions for resistant pseudomonal and<br />

pneumococcal pneumonia in the recent past, including ventilatory dependent respiratory failure. During<br />

this admission, she was started on ceftriaxone and azithromycin for community acquired pneumonia.<br />

Her CBC on the day <strong>of</strong> admission showed a hemoglobin <strong>of</strong> 11.2 g/dl, WBC 17.76 thousand/uL, and<br />

platelets 198 thousand/uL. On day two, piperacillin/tazobactam was started at 4.5 g IV q6h to cover for<br />

Pseudomonas aeruginosa. After one dose <strong>of</strong> piperacillin/tazobactam, platelets on the following day<br />

were 7.0 thousand/uL. Her repeat platelet count five hours later was 4.0 thousand/uL.<br />

Piperacillin/tazobactam was discontinued and was replaced with aztreonam. There was no heparin<br />

exposure and there was no evidence <strong>of</strong> hemolysis or DIC. She had petechiae noted on her arm, but no<br />

other signs <strong>of</strong> overt bleeding. After 6 units <strong>of</strong> platelets were transfused, the count improved to 33<br />

thousand/uL on the same day. Her platelet count five days after discontinuation <strong>of</strong><br />

piperacillin/tazobactam was 133 thousand/uL without any intervention. Another hospitalization<br />

occurred five months later with symptoms <strong>of</strong> fever and worsening cough. Initial platelet count was 157<br />

thousand/uL. After a single dose <strong>of</strong> piperacillin/tazobactam, platelets the next day were 40 thousand/uL.<br />

Due to the previous history <strong>of</strong> suspected thrombocytopenia from piperacillin/tazobactam, the antibiotic<br />

was switched to meropenem 1g IV q8h. Her platelets slowly improved and by the sixth day were 183<br />

thousand/uL. Given that the platelets dropped precipitously with rechallenge and recovered both times<br />

without any change in the treatment <strong>of</strong> HIV or treatment <strong>of</strong> HIV associated ITP, it was felt that the<br />

thrombocytopenia was due to piperacillin/tazobactam.<br />

DISCUSSION: Thrombocytopenia is a serious, but uncommon adverse effect <strong>of</strong> piperacillin/tazobactam<br />

and should be kept in mind while treating patients. The previously reported cases <strong>of</strong> thrombocytopenia<br />

have been gradual in onset, all occurring at >10 days. This case is unique in the rapid onset <strong>of</strong><br />

thrombocytopenia, and the cause was confirmed with rechallenge and recovery <strong>of</strong> the platelets<br />

occurred with discontinuation <strong>of</strong> only the piperacillin/tazobactam. We hypothesize that a unique<br />

mechanism <strong>of</strong> action may cause a more rapid onset <strong>of</strong> thrombocytopenia with piperacillin/tazobactam.<br />

Obstructive Jaundice, A rare complication <strong>of</strong> laparoscopic right hemicolectomy treated<br />

endoscopically.<br />

Shailendra Singh, MD, Shyam Thakkar, MD<br />

INTRODUCTION:Benign bile duct strictures postoperatively are major iatrogenic catastrophe and<br />

usually are complications <strong>of</strong> surgery for gallbladder stones, both open surgery and laparoscopic surgery.<br />

Laparoscopic colectomies are routinely performed for large and endoscopically unresectable polyps.<br />

However, development <strong>of</strong> biliary stricture after laparoscopic right hemicolectomy is an extremely rare<br />

condition and has not been reported in literature.<br />

CASE PRESENTATION: A 64 year old white female was referred to our institution for further evaluation<br />

and treatment <strong>of</strong> biliary complications after laparoscopic hemicolectomy. One week post laparoscopic<br />

surgery she developed sudden onset jaundice with dark urine, nausea and increasing epigastric and right<br />

upper quadrant abdominal pain. Physical examination revealed jaundice; mild tenderness in the right<br />

upper abdominal quadrant but no palpable mass or ascitis and the surgical scar was healed<br />

appropriately. Initial laboratory reports revealed an total bilirubin 10.8 mg/dl, direct bilirubin 6 mg/dl,<br />

alkaline phosphatase 306 U/L, alanine aminotransferase 307 U/L and aspartate aminotransferase 181<br />

U/L. Imaging studies revealed biliary dilation <strong>of</strong> both extra and intra hepatic ducts with no evidence <strong>of</strong><br />

bile duct stones. The ERCP showed an abrupt, complete obstruction <strong>of</strong> the CBD at the level <strong>of</strong> the<br />

surgical clips and multiple surgical clips across the CBD. The stricture improved significantly after serial<br />

incremental biliary dilatations with successive placement <strong>of</strong> increasing number <strong>of</strong> endoprostheses side<br />

by side at repeat ERCP sessions.<br />

DISCUSSION: Bile duct injury and stricture formation is not a known complication <strong>of</strong> right<br />

hemicolectomy but bile duct injury following laparoscopic right hemicolectomy is a possibility given the<br />

anatomical proximity <strong>of</strong> the right colon and hepatobiliary structures. We believe that bile duct injury in<br />

this patient was most likely a result <strong>of</strong> misplacement <strong>of</strong> surgical clips across the CBD. Early diagnosis <strong>of</strong><br />

these biliary strictures is imperative to prevent irreversible fibrosis and life-threatening complications,<br />

such as ascending cholangitis, liver abscess, and secondary biliary cirrhosis. Post operative bile duct<br />

injuries have been traditionally treated by surgical repair, usually a biliodigestive anastomosis mostly a<br />

proximal hepatico-jejunostomy with Roux-en-Y jejunal loop, but today endoscopic treatment is<br />

preferred. The excellent result obtained in our patient suggest that if the occluding surgical clip or the<br />

biliary stricture secondary to surgical clip is susceptible to dilation and stent insertion, endoscopic<br />

dilation and stent insertion should be adopted as a less invasive, first line approach to this problem as it<br />

can avoid a complicated and morbid surgical bypass.<br />

Pheochromocytoma Presenting As Cardiogenic Shock: An Atypical Case.<br />

Daniel John Spinuzzi M.D./M.B.A., William Rust M.D.<br />

INTRODUCTION: Pheochromocytoma is a rare neuroendocrine tumor derived from enterochromaffin<br />

cells and is found in less than 0.3% <strong>of</strong> hypertensive individuals. 0.01% present with shock. Symptoms<br />

typically include a triad <strong>of</strong> headache, palpitations and diaphoresis. Less common manifestations include<br />

acute myocardial infarction, arrhythmias, dilated cardiomyopathy, and in extreme cases, acute heart<br />

failure. We describe a patient presenting with cardiogenic shock and respiratory failure initially<br />

diagnosed with viral myocarditis and subsequently found to have a pheochromocytoma.<br />

CASE PRESENTATION: A 51 year old white female with a past medical history <strong>of</strong> hypertension<br />

presented to the emergency department complaining <strong>of</strong> chest pain, shortness <strong>of</strong> breath and several<br />

episodes <strong>of</strong> emesis over the preceding 2 days. Vital signs include a blood pressure <strong>of</strong> 60/30 mm Hg,<br />

heart rate <strong>of</strong> 130 beats per minute and respiratory rate <strong>of</strong> 34 /min. Physical exam revealed bilateral<br />

crackles and cool extremities. Sinus tachycardia with diffuse ST segment and T wave changes were seen<br />

on the initial electrocardiogram. She has a leukocyte count <strong>of</strong> 19.7 k/ml, BUN <strong>of</strong> 27 mg/dL, creatinine <strong>of</strong><br />

2.5 mg/dL, and elevated cardiac enzymes. An arterial blood gas revealed a pH <strong>of</strong> 6.99 and HCO3 <strong>of</strong> 6.6.<br />

Chest X-Ray revealed bilateral pulmonary edema. She was emergently intubated, and started on<br />

dopamine and dobutamine. An emergent cardiac catheterization revealed normal coronary arteries and<br />

severe left ventricular dysfunction with an ejection <strong>of</strong> 10%. An intra-aortic balloon pump was placed for<br />

hemodynamic support and the patient was evaluated for possible left ventricular assist device.<br />

In the CCU, systolic blood pressure ranged from 90-220 mm Hg and HR ranged from 120-280 bpm. She<br />

had urine metanephrine <strong>of</strong> 3195, total metanephrine 4838 and normetanephrine <strong>of</strong> 1643. Antihypertensive<br />

medical therapy included phentolamine, phenoxybenzamine and labetolol. Computed<br />

Tomography revealed a left adrenal mass highly suspicious for pheochromocytoma. Pathology from an<br />

abdominal tumor resection confirmed the diagnosis. The hospital course was complicated by acute renal<br />

failure and respiratory failure. She gradually improved post-operatively and a repeat echocardiogram<br />

revealed an EF <strong>of</strong> 65%. She was discharged to home without anti-hypertensive therapy.<br />

DISCUSSION: This case illustrates a near fatal presentation <strong>of</strong> Pheochromocytoma. Sudden release <strong>of</strong><br />

catecholamines may precipitate hemodynamic compromise and multi-system organ failure. Cardiac<br />

manifestations may include arrhythmias, angina, myocardial infarction, and acute heart failure.<br />

Catecholamine induced focal myocardial necrosis with inflammatory infiltration can cause pulmonary<br />

edema and LV dysfunction as seen in this patient and appears to be reversible with both medical<br />

management and subsequent removal <strong>of</strong> the tumor.<br />

Although rare, pheochromocytoma should be considered in patients that present with cardiogenic shock<br />

<strong>of</strong> unknown etiology. This case illustrates the significant morbidity and mortality associated with<br />

pheochromocytoma and the importance <strong>of</strong> recognizing its various clinical manifestations.<br />

A Case <strong>of</strong> Capnocytophagus and the Future <strong>of</strong> Identifying Infectious Disease Pathogens<br />

Daniel John Spinuzzi, MD MBA. William Rust M.D.<br />

INTRODUCTION:<br />

Capnocytophagus is a gram-negative bacillus that is part <strong>of</strong> the normal canine flora. The bacterium can<br />

cause devastating DIC, especially in asplenics. The organism requires an oxygen-rich environment and is<br />

difficult to isolate in culture. This vignette describes an asplenic patient presenting with overwhelming<br />

sepsis due to Capnocytophagus. The bacterium was unable to be isolated in culture at our facility and<br />

was only identified with Ibis T5000 technology.<br />

CASE PRESENTATION:<br />

A 67-year-old man presented with altered mental status and acute respiratory failure. He is asplenic<br />

secondary to a prior gunshot wound. The patient’s wife reported acute onset <strong>of</strong> “confusion” on the<br />

evening prior, along with several episodes <strong>of</strong> vomiting, a temperature <strong>of</strong> 104 degrees Fahrenheit and a<br />

non-productive cough. The patient was febrile at 105.2 and had a white blood count <strong>of</strong> 16.6. He was<br />

pan-cultured and started on vancomycin, ceftriaxone, acyclovir, as well as steroids for presumed<br />

meningitis. A lumbar puncture was unable to be performed because <strong>of</strong> a TENS unit. The patient was<br />

intubated and had cold extremities with multiple petechiae. The tip <strong>of</strong> his nose was also involved and<br />

cultures were redrawn. When checking a blood culture the lab noted “rod-shaped bacteria intra/extracellularly.”<br />

On hospital day one, the wife asked if a “dog bite” could be responsible, as the family dog<br />

“nipped” at the patient’s nose and caused a minor break in the skin on the day prior to evaluation. The<br />

differential now included Capnocytophaga Canimorsus. The patient’s DIC persisted and his<br />

extremity/nose necrosis continued to worsen. His somnolence continued despite sedation<br />

discontinuation. The family requested withdrawal. Multiple cultures from our facility were negative, as<br />

well as samples sent to outside facilities. The initial blood culture was later reported as likely<br />

Capnocytophagus species. Post-mortem, six <strong>of</strong> the blood samples were analyzed using state-<strong>of</strong>-the-art<br />

Ibis T5000, which is a universal biosensor that allows one to identify a broad range <strong>of</strong> pathogens without<br />

requiring an anticipated organism. All six <strong>of</strong> our patient’s samples were positive with Capnocytophaga<br />

Canimorsus.<br />

DISCUSSION: This vignette highlights the importance <strong>of</strong> identifying Capnocytophagus as a potential<br />

source <strong>of</strong> sepsis in those at risk. Due to fastidious growth requirements Capnocytophagus is difficult to<br />

culture. This case introduces Ibis T5000 technology as a potential game-changer in the world <strong>of</strong><br />

infectious disease and patient care. The system incorporates mass spectrometry and PCR technology to<br />

identify a broad range <strong>of</strong> pathogens such as bacteria, fungi, viruses, and protozoa including their<br />

resistance factors, in less than eight hours. The technology allowed us to identify an organism that we<br />

were unable to grow in culture.<br />

White Matter Abnormalities In A Patient With Legionerres’ Disease<br />

Matthew J Stanishewski, DO, Associate, Department <strong>of</strong> Medicine, Lankenau Hospital, Wynnewood<br />

Pennsylvania<br />

INTRODUCTION:The neurological manifestations seen in patients diagnosed with Legionerres’ disease<br />

have been well documented. Forty to fifty percent <strong>of</strong> cases will develop neurological signs and<br />

symptoms. However, radiological abnormalities accounting for these manifestations are exceedingly<br />

rare.<br />

CASE PRESENTATION: A 45 year old African <strong>American</strong> female with no significant past medical history<br />

presented after developing dry cough and fever with sudden onset <strong>of</strong> ataxia and pr<strong>of</strong>ound<br />

dysarthria. Her chest x-ray showed a right lower lobe infiltrate with lab studies showing mild elevation<br />

in her liver enzymes. In addition, a non-contrast computed tomography scan <strong>of</strong> the brain showed subtle<br />

peripheral subcortical white matter hypodensities without evidence <strong>of</strong> acute disease. A brain magnetic<br />

imaging study revealed numerous centrifugally placed, nonspecific foci <strong>of</strong> white matter signal<br />

abnormality on T2-weighted and FLAIR sequences. Initially, she was treated empirically with<br />

intravenous lev<strong>of</strong>loxacin and metronidazole. Within 24 hours, the patient’s ataxia had significantly<br />

improved, however, she continued to experience considerable dysarthria. A urinary legionella antigen<br />

was found to be positive the following day. Anti-nuclear antibodies, anti-neutrophil cytoplasmic<br />

antibodies and anticardiolipin antibodies were negative. An echocardiogram revealed normal left<br />

ventricular function without evidence <strong>of</strong> thrombi. Her antibiotic therapy was tailored to lev<strong>of</strong>loxacin<br />

alone and within 48 hours <strong>of</strong> treatment, her dysarthria had significantly improved. By 72 hours, her<br />

symptoms had completely resolved. She was subsequently discharged on a full 21 day course <strong>of</strong> oral<br />

lev<strong>of</strong>loxacin, without recurrence <strong>of</strong> her neurological sequelae.<br />

DISCUSSION: Previous case reports have demonstrated various brain imaging abnormalities associated<br />

with Legionella infection. Cases <strong>of</strong> reversible brain lesions have been reported. The mechanism <strong>of</strong><br />

neurological dysfunction in patients with Legionella pneumophila is currently unknown. One hypothesis<br />

proposes an endotoxin-mediated effect on central nervous system tissue. The lesions seen in our<br />

patient may represent cytotoxic edema in the setting <strong>of</strong> this proposed phenomenon. Due to the<br />

increasing availability <strong>of</strong> sensitive imaging methods, the finding <strong>of</strong> brain lesions in patients with<br />

Legionerres’ disease may be more common than previously acknowledged.<br />

SEVERE VITAMIN B12 DEFICIENCY MIMICKING THROMBOTIC THROMBOCYTOPENIC PURPURA<br />

Rashmi V Thatte MD<br />

INTRODUCTION: Thrombotic thrombocytopenic purpura (TTP) is a diagnosis made by clinical and<br />

biochemical features constituting the classic “pentad”: thrombocytopenia, microangiopathic hemolytic<br />

anemia (MAHA), fever, acute renal failure and neurological symptoms. Reversible causes like Vitamin<br />

B12 deficiency can also present similarly and should be ruled out in all patients with suspected TTP.<br />

CASE PRESENTATION: 83 year old African <strong>American</strong> male presented to the ER with complaints <strong>of</strong><br />

recent onset <strong>of</strong> severe weakness, loss <strong>of</strong> appetite and syncope. The review <strong>of</strong> systems was otherwise<br />

negative and the physical examination only revealed pallor. Past medical history was positive for reflux<br />

disease and colon cancer status post resection over 15 years ago. In the ED, laboratory results showed<br />

pancytopenia (white blood cell count <strong>of</strong> 3600/µL, hemoglobin <strong>of</strong> 5.5 g/dl with MCV <strong>of</strong> 93.8 fL and<br />

platelet count <strong>of</strong> 54,000/ µL), elevated creatinine <strong>of</strong> 2.3 mg/dl and indirect hyperbilirubinemia (indirect<br />

bilirubin = 2.3 mg/dl). Due to a very high clinical suspicion <strong>of</strong> TTP, a stat hematology consult was placed<br />

and the peripheral smear was reviewed immediately .The smear showed rare, isolated schistocytes and<br />

hence, plasmapharesis was held based on absence <strong>of</strong> evidence <strong>of</strong> active intravascular hemolysis.<br />

Subsequent tests confirmed hemolysis with lactate dehydrogenase (LDH) elevation to 1765 units/L and<br />

haptoglobin level < 10 mg/dl but suggested a bone marrow pathology as reticulocyte count was<br />

inappropriately normal (1.8%) for the severity <strong>of</strong> anemia. Direct and indirect Coomb’s tests were<br />

negative. The platelets continued to drop with a nadir <strong>of</strong> 17,000 / µL. Prior to subjecting the patient to<br />

an invasive bone marrow biopsy, vitamin B12 and folate levels were ordered. Folate level was normal (<br />

12.8 ng/ml ) but a vitamin B12 level <strong>of</strong> 42 pg/ml suggested severe deficiency , confirmed by a very high<br />

methylmalonic acid level ( 4000 nanomoles/ liter) and a high homocysteine level ( 20 micromoles/liter).<br />

Intrinsic factor antibodies were negative ruling out pernicious anemia. The patient was given<br />

intramuscular injections <strong>of</strong> 1000 micrograms <strong>of</strong> vitamin B12 daily for one week with a marked response<br />

<strong>of</strong> the platelet count and reticulocyte count along with a gradual downward trend <strong>of</strong> LDH.<br />

DISCUSSION: Vitamin B12 deficiency causes pancytopenia by direct bone marrow suppression. It is also<br />

thought to cause intramedullary hemolysis due to increase red blood cell membrane rigidity. Lysis <strong>of</strong><br />

immature nucleated red cells in the bone marrow can lead to an elevated LDH level, a microangiopathic<br />

smear, and a low haptoglobin level. Simple tests like peripheral smear, vitamin B12 level and<br />

methylmalonic acid level can be extremely useful in ruling out a deficiency state which can clinically<br />

present like TTP.<br />

Pneumopericardium, Pneumomediastinum, Pneumoperitoneum, Pneumoretroperitoneum and<br />

Subcutaneous Emphysema Post Colonoscopy.<br />

Hao Nguyen, MD Second Author: Jayaram Thimmapuram, MD Third Author: Vipul Bhatia, MD<br />

INTRODUCTION: Colonoscopy is a widely performed procedure. Bowel perforation is a rare<br />

complication reported in about 0.4-1.9% <strong>of</strong> cases. It is the most serious and awful adverse event which<br />

can lead to a death. Supradiaphragmatic complications <strong>of</strong> colonoscopy have been rarely reported. We<br />

report a rare case <strong>of</strong> pneumopericardium, pneumomediastinum, pneumoretroperitoneum,<br />

pneumoperitoneum and subcutaneous emphysema after a colonoscopic procedure without evidence <strong>of</strong><br />

perforation.<br />

CASE PRESENTATION: A 76-year-old caucasian female with history <strong>of</strong> uncontrolled hypertension and<br />

hypothyroidism underwent an elective screening colonoscopy. Her medications included<br />

hydrochlorothiazide, omeprazole, multivitamins and fex<strong>of</strong>enadine. Colonoscopy revealed four small<br />

polyps which were removed successfully without any major bleeding observed. However, about thirty<br />

minutes following the colonoscopy, patient had an acute onset <strong>of</strong> severe retrosternal chest pain, sharp<br />

and pressure like in nature, rated to be 10/10 that started from the anterior retrosternal and radiating<br />

to her back. The chest pain was constant but improved slightly with intravenous pain medication.<br />

However, the episodes <strong>of</strong> pain came back again. The pain worsened with deep inspiration. During the<br />

event, her blood pressure was found to be 197/92 with heart rate <strong>of</strong> 110. Her saturation however,<br />

maintained 95% at 2 Litter <strong>of</strong> Oxygen through nasal canula. An urgent CAT scan <strong>of</strong> the chest, abdomen<br />

and pelvis was done which showed pneumomediastinum and pneumopericardium with air dissecting<br />

into the neck and the retroperitoneum and into the abdominal wall muscles on the right. Urgent<br />

exploratory laporoscopy was done which did not show any evidence <strong>of</strong> perforation. Patient clinically<br />

improved after the procedure and hemodynamically stable with routine medical care. Intravenous<br />

lev<strong>of</strong>loxacin and metrodinazole were started empirically. She responded well with conservative<br />

management without a laparotomy. She tolerated slowly advanced diets. Patient was discharged after 4<br />

days with oral metrodinazole for 3 more days and set outpatient follow up with gastroenterologist and<br />

surgeon.<br />

DISCUSSION: Colonic perforation can lead to extra intestinal collection <strong>of</strong> air. However,<br />

supradiaphragmatic complications including pneumomediastinum and pneumopericardium have been<br />

only rarely reported. In our patient, there was no evidence <strong>of</strong> perforation seen on exploratory<br />

laparoscopy. Different mechanisms have been proposed whereby extra-luminal air may reach the<br />

different body compartments. Forcible herniation <strong>of</strong> the colonic mucosa has been suggested, such that<br />

the mucosa becomes permeable to air without an actual perforation developing. Air may pass along the<br />

mesentery to the retroperitoneum and then to the mediastinum along the fascial planes.<br />

Pneumomediastinum can lead to a pneumothorax or pneumopericardium when the mediastinal parietal<br />

pleura or the pericardium ruptures. In summary, we describe an interesting case <strong>of</strong> extraluminal and<br />

supradiaphragmatic collection <strong>of</strong> air post colonoscopy without evidence <strong>of</strong> perforation.<br />

Treating Steroid-refractory Dermatomyositis Associated with Severe Dysphagia with Intravenous<br />

Immune Globulin<br />

Aubre A Weber, DO, Associate, Shakaib S. Qureshi, MD, Section Chief - Department <strong>of</strong> Rheumatology,<br />

Christiana Care Health System, Newark, DE.<br />

INTRODUCTION: Dysphagia associated with dermatomyositis is <strong>of</strong>ten treated with corticosteroids and<br />

later with immunosuppressive maintenance therapies. Intravenous immune globulin (IVIG) is<br />

not currently used as first line treatment for complications arising from dermatomyositis. However, new<br />

literature has suggested that in complement-damaged tissue as seen in this inflammatory myopathy,<br />

IVIG appears to modulate and minimize complement attack.<br />

CASE PRESENTATION: A 63 yr old Hispanic female presented with a diffuse macular rash and upper<br />

extremity weakness. On exam, she was noted to have diffuse anasarca, an erythematous, macular rash<br />

over her eyes, neck, shoulders, gottron’s papules on bilateral PIP and MCP joints and symmetric<br />

proximal weakness noted in her upper extremities. Muscle biopsy showed an inflammatory myopathy<br />

with serology demonstrating elevated sedimentation rate, creatinine kinase (CK), aldolase, liver function<br />

tests, as well as a positive ribonucleoprotein (RNP) antibogy IgG and anti-Ro IgG antibodies. She was<br />

diagnosed with dermatomyositis during this visit and discharged with a steroid taper and follow up with<br />

rheumatology. Unfortunately, she returned to the emergency department one week later with<br />

dysphagia. Speech therapy witnessed large silent aspiration events on exam and the patient had a<br />

feeding tube placed shortly thereafter. Again, the patient was placed on steroids with little effect. No<br />

improvement was observed in the patient’s dysphagia and in fact, her liver function, muscle enzymes<br />

and overall condition continued to worsen. Decision was made to treat with IVIG administration,<br />

400mg/kg/day for 5 days, which she tolerated well. Her laboratory data progressively improved and<br />

approximately 9-10 days after IVIG infusion, swallow evaluation showed patient to be protecting her<br />

airway when given thickened liquids. Her diet was advanced and steroid taper was started. Treatment<br />

with azathioprine was considered but her TMPT status was tested and she was determined to be<br />

deficient. A small portion <strong>of</strong> the population is TPMT-deficient. Low TMPT levels can lead to thiopurine<br />

drugs, such as azathioprine, being inefficiently metabolized. This can lead to severe and possibly fatal<br />

toxicity as the unmetabolized drug accrues in the bone marrow. The risk <strong>of</strong> methotrexate therapy was<br />

also high due to resolving transaminitis so the patient was eventually discharged with continued steroid<br />

taper and IVIG follow-up infusions monthly for 3-6 months.<br />

DISCUSSION: Although effectiveness has been shown in some small studies using IVIG in<br />

dermatomyositis-related complications such as dysphagia, the mechanism <strong>of</strong> its action is still not<br />

completely clear. This case highlights the need for further research in regards to treating steroidrefractory<br />

dermatomyositis associated with severe complications with IVIG. In addition, IVIG as a single<br />

maintenance therapy in patients with a documented inability to receive maintenance therapies such as<br />

methotrexate and/or azithioprine has yet to be clearly shown as a reliable treatment<br />

modality. Dysphagia associated with dermatomyositis leads to an elevated mortality rate, and a proven<br />

as well as consistent acute and maintenance therapy in this potentially life-threatening condition is<br />

necessary.<br />

Jejunal Diverticulitis: A Rare Cause Of Abdominal Pain<br />

Yang ZJ, Ripepi BM, Fritz JM, Rahman A, Nusrat S<br />

INTRODUCTION: The prevalence <strong>of</strong> jejunal diverticula is estimated to be 1.1-2.3%. Complications <strong>of</strong><br />

jejunal diverticular disease (JDD) include diverticulitis, hemorrhage, bowel obstruction, perforation and<br />

blind loop syndrome. JDD can present as acute abdomen or chronically with non-specific symptoms such<br />

as nausea, emesis or recurrent central/upper abdominal pain that may mimic gastritis, peptic disease or<br />

irritable bowel syndrome. As a rare entity, the diagnosis <strong>of</strong> JDD is <strong>of</strong>ten not deliberated and is frequently<br />

made incidentally through imaging or intra-operatively.<br />

CASE PRESENTATION: A 63 year old female with no prior history <strong>of</strong> colonic diverticular disease<br />

presented with an acute onset, severe, localized, left sided abdominal pain. Pain was associated with<br />

emesis, constipation and a temperature <strong>of</strong> 38.3°C. Exam revealed decreased bowel sounds, left sided<br />

abdominal tenderness and the absence <strong>of</strong> guarding or rigidity. Exam was otherwise unremarkable. Labs<br />

revealed mild leukocytosis <strong>of</strong> 12.1 with neutrophilic predominance. CT was significant for acute jejunal<br />

diverticulitis. A further small bowel follow through confirmed numerous jejunal diverticula. Given its<br />

assciation with scleroderma, auto-antibody screen with ANA and Scl-70 had a negative yield.<br />

Conservative management with NPO, intravenous fluids and ampicillin-sulbactam led to resolution <strong>of</strong><br />

symptoms within 48 hours.<br />

DISCUSSION: We report a case <strong>of</strong> uncomplicated jejunal diverticulitis that resolved promptly with<br />

conservative management. Uncomplicated JDD, precluding perforating events with peritonitis are best<br />

managed with a trial <strong>of</strong> conservative management prior to surgical consideration. Pathogenesis <strong>of</strong> JDD is<br />

suggested to result from small bowel motor dysfunction that can be associated with scleroderma. In<br />

patients with history <strong>of</strong> scleroderma, JDD must be considered in the setting <strong>of</strong> GI symptoms. Autoantibody<br />

screening can be recommended in undiagnosed patients. While the diagnosis <strong>of</strong> JVD is an<br />

insightful finding, further management <strong>of</strong> uncomplicated JVD remains one <strong>of</strong> ‘watch and wait’ when the<br />

general consensus places little value for surgical intervention. Chronic presentation <strong>of</strong> JVD can mimic<br />

gastritis, peptic disease or irritable bowel syndrome. The role <strong>of</strong> screening with CT imaging is limited as<br />

sensitivities for diverticula are marginal and can be missed as bowel loops or colon. The utility <strong>of</strong> postduodenal<br />

endoscopy to rule out JVD in patients presenting with IBS associated features remains to be<br />

determined.<br />

Viral syndrome, a nearly lethal presentation<br />

Julio Valentin Nieves, MD<br />

INTRODUCTION:Leptospirosis is a zoonotic disease characterized by a spectrum <strong>of</strong> clinical<br />

manifestations ranging from subclinical to fulminant, potentially fatal infection. Mortality is usually<br />

associated to multiorgan failure. Cardiac disturbances range from ECG changes to overt myocarditis. In<br />

the clinical setting, cardiac pathology is generally masked by overt pulmonary and/or hepatorenal<br />

syndromes and therefore, overlooked or underestimated. In this case we see the initial an initial<br />

presentation mimicking a viral syndrome that later progressed to cardiac complications, including ST<br />

elevation miocardial infarction, miocarditis and acute respiratory distres syndrome.<br />

CASE PRESENTATION: 31 year old man with history <strong>of</strong> traumatic brain injury who came to the<br />

emergency room with a chief complaint <strong>of</strong> general malaise, unquantified fever, chills, myalgia, anorexia,<br />

and nausea without vomiting <strong>of</strong> 3 days evolution, with associated headache, sore throat, and<br />

nonproductive cough. Upon evaluation, he was found hypotensive, tachycardic, and febrile. Physical<br />

exam was remarkable for dry oral mucosa, mild pharyngeal erythema, and bilateral conjunctival<br />

suffusion. He recently traveled to the Dominican Republic. Initial labs were remarkable for leukocytosis,<br />

thrombocytopenia, hyponatremia, elevated creatinine kinase, and normal bilirubin. He was admitted<br />

with a diagnostic impression <strong>of</strong> viral syndrome and a working diagnosis <strong>of</strong> Dengue Fever. On hospital<br />

day 1, after an episode <strong>of</strong> loss <strong>of</strong> consciousness (LOC), ECG demonstrated sinus tachycardia, with 2-4mm<br />

ST elevation in anterior leads. Shortly after, he suffered a second episode <strong>of</strong> LOC accompanied by a selfresolving<br />

polymorphic ventricular tachycardia (VT) resembling torsade de pointes. Despite adequate<br />

management, he continued with chest pain and positive cardiac enzymes. Emergent coronary<br />

angiography failed to reveal any obstructive lesions or vasospasm. Ventriculography showed mildly<br />

reduced ejection fraction with segmental wall motion abnormalities. He persisted with episodes <strong>of</strong> nonsustained<br />

VT, worsening dyspnea, and developed blood tinged sputum. Chest x-ray was remarkable for<br />

bilateral confluent infiltrates, suggestive <strong>of</strong> alveolar hemorrhage. Clinical status continued to deteriorate<br />

due to a 3rd episode <strong>of</strong> LOC and a 2nd recorded polymorphic VT that required defibrillation and IV<br />

antiarrhythmics. The patient also required mechanical ventilation with protective lung parameters.<br />

Diffuse alveolar hemorrhage was diagnosed by bronchoalveolar lavage. Broad-spectrum antibiotics were<br />

started empirically. Work up for Influenza, Echovirus, Leptospira, Enterovirus, Coxsackie, Epstein-Barr<br />

virus, Cytomegalovirus, and Dengue was sent. The patient’s clinical status dramatically improved.<br />

Eventually convalescent antibody titers for leptospira were reported positive making leptospiral<br />

myocarditis the likely diagnosis.<br />

DISCUSSION: Leptospirosis is a zoonotic disease characterized by a spectrum <strong>of</strong> clinical manifestations<br />

ranging from subclinical to fulminant, potentially fatal infection. Mortality is usually associated to<br />

multiorgan failure. Cardiac disturbances range from ECG changes to overt myocarditis. In the clinical<br />

setting, cardiac pathology is generally masked by overt pulmonary and/or hepatorenal syndromes and<br />

therefore, overlooked or underestimated. Proposed mechanisms <strong>of</strong> arrhythmogenesis include<br />

inhomogeneous repolarization and unstable membrane potentials in cardiomyocites secondary to tissue<br />

inflammation. To our knowledge, there are no cases in the literature <strong>of</strong> anicteric leptospiral myocarditis<br />

with coexistence <strong>of</strong> ST segment elevation-mimicking STEMI, polymorphic VT resembling torsade de<br />

pointes, and diffuse alveolar hemorrhage with Acute Respiratory Distress Syndrome (ARDS) as<br />

presenting entities. This case confirms the non-specific presentation <strong>of</strong> anicteric leptospirosis and<br />

suggests that a high clinical suspicion along with early antibiotic therapy might prevent morbidity and<br />

mortality.<br />

Pedro MD, Rivera-Caroline MD, Baez-Luis MD, Nieves-Dalila MD, Mendez-Angela MD<br />

INTRODUCTION:Leukemia is a type <strong>of</strong> cancer <strong>of</strong> the blood or bone marrow (BM) characterized by an<br />

abnormal increase <strong>of</strong> WBC's.<br />

Medical literature has described rare tumors composed <strong>of</strong> a solid collection <strong>of</strong> leukemic cells with a<br />

normal BM. One example is Extramedullary Myelogenous Leukemia (EMML) that are uncommonly seen<br />

even by oncologists.<br />

CASE PRESENTATION: A 36 year old nulliparous female with no systemic illness went to her physician<br />

after she noted bilateral breast lumps on a self breast exam. Fever, night sweats or weight loss were<br />

denied. Breast inspection showed her right breast bigger than the left and without skin lesions. During<br />

palpation a 3cm nontender rubbery mass at the 2 o’clock position <strong>of</strong> the right breast and a1cm mass at<br />

the 12 o’clock position <strong>of</strong> the left breast were identified. Nipple retractions, discharges<br />

or lymphadenopathies weren’t evident. In the inspection <strong>of</strong> her lower back, 2 brown irregular skin<br />

papules <strong>of</strong> 2 cm were identified. Breast studies revealed multiple complex nodules not present on<br />

previous exams four years ago. Bilateral breast MRI showed numerous gadolinium ill<br />

defined borders enhancing masses, too numerous to count. Biopsy <strong>of</strong> the right breast mass<br />

demonstrated an EMMT positive for CD34, CD43, CD 117 and Ki 67 present in 60% <strong>of</strong> the cells, a<br />

proliferation marker. Bone marrow biopsy (BMB) was negative for Acute Myeloid Leukemia (AML). She<br />

was referred to MD Anderson Cancer Center and the diagnosis <strong>of</strong> EMMT was confirmed. The biopsy <strong>of</strong><br />

the skin lesions on her back was consistent with the diagnosis <strong>of</strong> Leukemia Cutis. After induction<br />

chemotherapy the breast lesions were not palpable and the papules on her back decreased in size.<br />

DISCUSSION: An EMMT is composed <strong>of</strong> immature myeloid precursor cells. There are many body<br />

presentations but breast involvement occurs in only 6% <strong>of</strong> cases. The symptoms are related to the<br />

anatomical localization but also can be incidentally found in asymptomatic patients. This type <strong>of</strong> tumor<br />

is easily misdiagnosed as a lymphoma or fibrocystic breast disease, making the diagnosis a real<br />

challenge. The successful approach to the patient’s clinical presentation is based on the early suspicion<br />

<strong>of</strong> a rare but possible diagnosis. The last BMB concluded that her BM is free <strong>of</strong> disease 13 months after<br />

the diagnosis, even though the mean to develop BM AML is 8 months. To our knowledge, there are<br />

only 4 case reports free <strong>of</strong> BM disease after 13 months or more <strong>of</strong> the EMMT diagnosis. We have<br />

diagnosed case number 5.<br />

A RARE CAUSE OF RAPIDLY PROGRESSING PNEUMONIA IN A YOUNG PATIENT<br />

Victor J Mariano, MD second Author: Juan Vázquez, MD Third Autho: Rodrigo Valderrabano, MD<br />

INTRODUCTION: Recurrent sinopulmonary infection is the most common illness associated with IgA<br />

deficiency (IgAD) patients. Most upper and lower respiratory tract infections are caused by bacterial or<br />

viral pathogens characteristic <strong>of</strong> community-acquired pneumonia.<br />

CASE PRESENTATION: A 33 year-old woman arrived at our Emergency Department after having been<br />

woken from sleep at 4:00am with complaints <strong>of</strong> shortness <strong>of</strong> breath, dry cough and right sided chest<br />

pain that increased with breathing. ABG’s ordered in the E.D. revealed an oxygen saturation <strong>of</strong> 90%,<br />

PaO2 at 67mmHg and a PaCO2 at 29 mmHg, the chest radiograph revealed a right lung base mild opacity<br />

that could be interpreted as “Hampton hump”. These findings in conjunction with a history <strong>of</strong> right foot<br />

orthopaedic surgery 2 weeks before developing symptoms and the sudden nature <strong>of</strong> disease<br />

progression led us to the working diagnosis <strong>of</strong> pulmonary embolism (P.E.). A spiral CT scan was ordered<br />

but revealed right lower lobe pneumonia instead <strong>of</strong> the characteristic findings <strong>of</strong> P.E. A second CT scan<br />

performed in 48hrs as per radiologist’s recommendation showed progression to a bilateral lower lobe<br />

pneumonia.<br />

DISCUSSION: Our patient’s initial presentation although typical <strong>of</strong> a P.E. was instead the result <strong>of</strong> a<br />

pneumonic process. Rapid progression to a bilateral pneumonia was however uncharacteristic <strong>of</strong> this<br />

patient’s age group. Further history revealed sinusitis since the patient was 9 years old twice per year<br />

until she turned 18, a hospitalization for pneumonia at age 24, 3 episodes <strong>of</strong> bronchitis the last one at 30<br />

years old and a recent diagnosis <strong>of</strong> ulcerative colitis. This added past medical history was suspicious for<br />

an immunoglobulin deficiency. Immunoglobulin levels were ordered on two different occasions four<br />

weeks apart and results showed IgA level less than 15 on both tests, which is the lowest possible<br />

reference value on that particular laboratory. The diagnosis <strong>of</strong> IgA deficiency was made.<br />

Immunoglobulin deficiency although not common, must be always scrutinized in patients with recurrent<br />

infections and prior history <strong>of</strong> autoimmune diseases. This case is an example <strong>of</strong> the importance <strong>of</strong><br />

establishing a wide differential diagnosis in cases with recurrent infections.<br />

From Bee Sting to Acute Kidney Injury and Rhabdomyolysis.<br />

Azar Sadeghalvad, MD, Francisco Jaume-Anselmi, MD, FACP, Amaury Segarra, MD, José Ramírez-Rivera,<br />

MD, MACP,<br />

INTRODUCTION: Africanized bees are spreading over the <strong>American</strong> hemisphere since they were<br />

accidentally released in Brazil 5 decades ago, and were introduced to Puerto Rico in 1994. Their massive<br />

attacks can cause less common nonallergic multi-system involvement ranging from rhabdomyolysis and<br />

acute renal failure.<br />

CASE PRESENTATION: An 86-year-old healthy farmer, a retired physician, experienced massive bee<br />

stings attack after he accidentally disturbed an Africanized bee colony, and was found on the ground 1.5<br />

hr later. On admission, he was conscious, mumbling due to facial and buccal edema with diffuse body<br />

aches, without loss <strong>of</strong> bladder or bowel control. The T was 35.7 º C, RR 16, P 96, and BP 161/87. There<br />

were over 400 bee sting marks on his head, and neck. There was bilateral periorbital, auricular, and<br />

buccal edema, with many bee stings inside his mouth. The leukocyte count was 18.5 (N 86, L 1, B 12, M<br />

1), Hb 15.7, Hct 45.9%, and Plt 151,000. The Glucose was 92, sodium 138, K 4.3, Cl 106, HCO3 20, BUN<br />

31and Cr 2.1. An arterial blood sample (100% FIO2) showed pH 7.38, PCO2 39.5, HCO3 24, PO2 133 and<br />

SaO2 100%. The ECG, chest film, head CT, and renal ultrasound were within normal limits. He was<br />

treated with Solumedrol 125 mg IV, Benadryl 50 mg IV, 0.9 NSS 100 ml/hr, and epinephrine 1mg IM,<br />

with a meticulous effort to remove all stings. He was admitted with systemic inflammatory response<br />

syndrome, due to massive bee stings. He was continued with Zosyn 2.25 gr IV q 6 hr, Solumedrol 80 mg<br />

IV q 8 hr, Benadryl 50 mg IV q 8 hr, and normal saline at 150 ml/hr. Four hours after admission, CPK was<br />

5,034 U/L, BUN 10, Cr 0.84 and the urinalysis showed large blood, moderate RBC, and few granular<br />

casts. Fourteen hours after admission, BUN, Cr, and CPK had increased to 67, 4.5, and 13,108<br />

respectively. A urine myoglobin <strong>of</strong> 7,950 mcg/L confirmed rhabdomyolysis. Aggressive volume<br />

replacement followed by Lasix, Mannitol, and HCO3 drip did not produce any diuretic response. The<br />

chest radiograph showed congestive changes with bilateral pleural effusions, and hemodialysis (HD) was<br />

initiated. He was discharged after 8 days with a Cr <strong>of</strong> 7.1, and a CPK <strong>of</strong> 1,642. HD was required for 1<br />

month.<br />

DISCUSSION: Clinicians need to be aware that anyone who experiences massive bee envenomation<br />

requires close observation, even if they appear to be well, as rhabdomyolysis and renal failure<br />

can present after 24 hours. Serum CPK, liver, and renal function must be monitored. Aggressive volume<br />

replacement is required to protect kidney function.<br />

INTRODUCTION: ANCA associated rapidly progressive glomerulonephritis (RPGN) is a disorder with<br />

significant morbidity that <strong>of</strong>ten presents with end stage renal disease. We present a case <strong>of</strong> a patient<br />

with previously undiagnosed microscopic polyangiitis (MPA) and a normal creatinine on hospital<br />

admission who subsequently developed RPGN requiring pulse dose steroids and cyclophosphamide<br />

therapy during his stay.<br />

CASE PRESENTATION: A 68 year-old gentlemen from the Dominican Republic presented to our<br />

hospital with the chief complaint <strong>of</strong> recurrent rectal prolapse. This was reduced in the Emergency<br />

Department, but the patient was admitted after he was incidentally found to have a fever and white<br />

blood cell count <strong>of</strong> 21,000. The patient’s only other complaint on admission was general malaise. His<br />

exam at the time <strong>of</strong> admission revealed no skin, joint, cardiac, or pulmonary abnormalities. Over the<br />

course <strong>of</strong> 11 days, an extensive infectious work-up for his fever and leukocytosis was conducted,<br />

including blood cultures, urine cultures, chest radiography, and serologies for tick-borne illnesses, fungal<br />

species, and tuberculosis, all <strong>of</strong> which were unrevealing. Finally, on hospital day 12, an ANCA screen<br />

revealed a positive pANCA with high positive myeloperoxidase antibody and normal proteinase 3<br />

antibody. Over the next two hospital days he developed worsening renal failure with dysmorphic red<br />

cells in his urine sediment. He then underwent renal biopsy which showed a crescentic<br />

glomerulonephritis with crescents in over 50% <strong>of</strong> his glomeruli. This confirmed the diagnosis <strong>of</strong> RPGN<br />

secondary to MPA. Methylprednisolone was initiated while biopsy results were pending, and<br />

cyclophosphamide was added afterward. The patient’s creatinine peaked at 2.84 mg/dl from 1.0 mg/dl<br />

on admission, and improved to 1.9 mg/dl two weeks after discharge.<br />

DISCUSSION: MPA is a relatively rare autoimmune condition involving arterial damage that can affect<br />

multiple organ systems, including respiratory, renal, and more rarely cardiac, nervous and GI<br />

systems. The initial symptoms are usually vague malaise, myalgias, and fevers, as was the case with our<br />

patient. In many instances, patients present only after significant end-organ damage has already<br />

occurred. This is more <strong>of</strong>ten the case with renal involvement where patients present after noting<br />

hematuria, edema, or dyspnea from volume overload. In fact, a University <strong>of</strong> North Carolina study<br />

showed that the average serum creatinine <strong>of</strong> patients presenting to their institution with this disorder<br />

was 6.5 mg/dl. Our patient, with no findings <strong>of</strong> vasculitis on admission, developed crescentic<br />

glomerulonephritis from MPA two weeks into his hospital stay. We believe that the patient’s early<br />

presentation allowed the diagnosis and treatment <strong>of</strong> this severe disorder to occur much earlier than<br />

expected, thus allowing for more significant renal recovery.<br />

INTRODUCTION: Cogan syndrome is a rare autoimmune condition characterized by inflammation <strong>of</strong><br />

the cornea and vestibuloauditory system.<br />

CASE PRESENTATION: Mr. MH is a 37 year-old healthy gentleman who presents to the emergency<br />

department with a one-month history <strong>of</strong> progressively worsening eye irritation, hearing loss and<br />

disequilibrium. His symptoms began with blurry vision and extreme photophobia. He saw no<br />

improvement with prescription antibiotic eye drops. One morning, he felt dizzy, nauseous and unsteady<br />

on his feet. He also noticed gradual hearing loss. A head CT scan was unremarkable, and a neurologist<br />

recommended a brain MRI and ENT referral. One week later, he returned to the ED for unrelenting<br />

symptoms. He had lost hearing in his left ear and his right ear responded only to very loud sounds. Over<br />

this period, Mr. MH reported a 15-pound weight loss and a diffuse infra-orbital headache; he denied<br />

fevers, joint aches, urethral discharge or skin rashes.<br />

On exam, Mr. MH is afebrile, blood pressure 124/68, pulse 68. He is a well-built gentleman, in distress,<br />

who is speaking clearly and fluently in a booming voice. He has extensive tearing and conjunctival<br />

injection with hazy corneas. Pupils are sluggish but reactive. Tympanic membranes are clear. Bone<br />

conduction is greater than air conduction bilaterally without Weber lateralization. Cardiovascular and<br />

pulmonary exam are unremarkable. Visual acuity is 20/30 in the right eye and 20/80 in the left eye.<br />

Strength is 5/5 in all extremities, sensation is intact to light touch and he has no dysmetria. He has an<br />

ataxic gait and a positive Romberg’s sign. Laboratory data include a normal CBC, normal BMP, ESR 37,<br />

CRP 23. Autoimmune serology include normal C3, C4, and negative ANA, ANCA, ds-DNA, SS-A, SS-B,<br />

cryoglobulin, RPR, lyme. Hsp-70 (anti-KD 68 antigen) was negative. A head and neck MRI/MRA showed<br />

no evidence <strong>of</strong> vasculitis.<br />

Mr. MH was admitted to the medicine service for these constellation <strong>of</strong> symptoms which define Cogan<br />

syndrome. Slit lamp exam confirmed interstitial keratitis. An audiometry evaluation was revealing for<br />

moderately-severe sensorineural hearing loss on the right and pr<strong>of</strong>ound loss on the left. Mr. MH was<br />

treated with salumedrol IV and prednisolone eye drops. His visual acuity improved, his hearing<br />

recovered and he no longer required a cane to walk.<br />

DISCUSSION: The treatment <strong>of</strong> Cogan syndrome, which includes high-dose steroids, is a common<br />

approach towards an otherwise uncommon condition marked by ocular inflammation and<br />

vestibuloauditory dysfunction. Mr. MH’s story is a heroic account <strong>of</strong> a vulnerable inmate with no means<br />

<strong>of</strong> communication, who responded beautifully to a course <strong>of</strong> steroids, and has emerged as a confident<br />

gentleman who can now see, hear and walk.<br />

Klebsiella In My Joint : A Case Of Klebsiella Pneumoniae Septic Arthritis<br />

Michele Therese L Yamamoto MD; Michael C Agustin MD; Teresa Slomka MD; John P Miskovsky MD;<br />

Marguerite Neill MD.<br />

INTRODUCTION:Staphylococcus aureus and Streptococci are predominant pathogens causing septic<br />

arthritis <strong>of</strong> native joints. We report a case <strong>of</strong> septic arthritis caused by Klebsiella pneumoniae for which<br />

there are a few published reports.<br />

CASE PRESENTATION: An 88-year old man was admitted with fever and mild confusion after a fall<br />

from his chair. Three weeks earlier he was hospitalized for possible community acquired pneumonia<br />

treated with Moxifloxacin. One week later, he developed right shoulder pain. Past medical history<br />

includes ischemic cardiomyopathy with biventricular pacing defibrillator, chronic kidney disease after a<br />

nephrectomy and IVC filter for a pulmonary emboli. On physical exam, he was lucid and febrile. His right<br />

shoulder was tender to palpation without erythema and had limited range <strong>of</strong> motion. Vancomycin and<br />

Ceftriaxone were started. CT scan showed a chronically torn rotator cuff and severe degenerative joint<br />

disease with no evidence <strong>of</strong> fracture or joint effusion. Intra-articular steroid injection was planned. As<br />

the local anesthesia was about to be injected, an aspirate <strong>of</strong> the joint fluid returned 15cc <strong>of</strong> purulent<br />

fluid which immediately clotted. There were sheets <strong>of</strong> neutrophils but no organisms on gram stain.<br />

Calcium pyrophosphate crystals were noted. Both blood and joint cultures yeilded Klebsiella<br />

pneumoniae. Urine analysis and urine culture were negative. Arthroscopic incision and drainage was<br />

done and the patient defervesced with improvement <strong>of</strong> shoulder pain. Removal <strong>of</strong> the cardiac device<br />

was not feasible and a 6-week course <strong>of</strong> intravenous Cefazolin was instituted. At 4 weeks <strong>of</strong> follow-up,<br />

the patient is doing well without systemic signs <strong>of</strong> infection, negative blood cultures and improving<br />

range <strong>of</strong> motion <strong>of</strong> the joint.<br />

DISCUSSION: Current English literature identifies only 19 reported cases <strong>of</strong> Klebsiella pneumoniae<br />

septic arthritis. Risk factors include chronic underlying disease such as diabetes, liver and chronic renal<br />

disease, malignancy and HIV. Most cases arise from hematogenous transmission from distant sites <strong>of</strong><br />

infection such as respiratory, gastrointestinal and urinary source. Treatment includes joint incision and<br />

drainage and parenteral antibiotics. Klebsiella pneumoniae strains are usually susceptible to<br />

Cephalosporins but those that produce an extended spectrum beta-lactamase require Carbapenem<br />

therapy. Poor outcomes are observed in patients with pre-existing joint disease, prosthetic joints and in<br />

those whom incision and drainage is not done. Although enteric bacilli account for less than 25% <strong>of</strong><br />

septic arthritis, antibiotic coverage for these pathogens should be included initially in cases <strong>of</strong> septic<br />

arthritis, particularly when the gram stain <strong>of</strong> joint fluid is negative and the patient is<br />

immunocompromised. Early and appropriate antibiotic treatment and surgical debridement strongly<br />

contributed to the successful outcome <strong>of</strong> this patient's infection.<br />

lemierre’s Syndrome: An Uncommon Complication Of A Common Condition, Ashley N. Latos, Md,<br />

Associate, Department Of Medicine, Medical University Of South Carolina, Charleston, Sc<br />

Ashley N Latos, MD<br />

INTRODUCTION: Lemierre’s Syndrome is a condition characterized by septic thrombophlebitis and<br />

bacteremia, <strong>of</strong>ten associated with the bacteria Fusobacterium necrophorum. Although a rare condition,<br />

it <strong>of</strong>ten follows common oropharyngeal infections such as tonsillitis and dental infections. Its<br />

complications include septic pulmonary emboli that can lead to hypoxemia, empyema and lung<br />

cavitation.<br />

CASE PRESENTATION: A 19-year-old Hispanic male with no past medical history presented with five<br />

days <strong>of</strong> malaise, fevers and hemoptysis that were preceded by a sore throat. Initial work-up revealed a<br />

fever <strong>of</strong> 103.5, WBC 18.6, platelets 24, D-dimer >500 and elevated ESR and CRP. Liver function tests<br />

were also elevated as well as total and direct bilirubin. CT scan was negative for pulmonary embolus but<br />

revealed numerous cavitary nodules bilaterally, concerning for septic emboli, as well as consolidation in<br />

the lower lobes bilaterally, concerning for pneumonia. Physical exam was notable for jaundice,<br />

tachycardia, decreased breath sounds in bilateral lung bases as well as crackles in the left lower<br />

lung. Doppler Ultrasound revealed a left internal jugular vein clot. His initial anaerobic blood culture<br />

bottle grew Fusobacterium necrophorum. A diagnosis <strong>of</strong> Lemierre’s syndrome was made and<br />

appropriate antibiotics were initiated. He developed acute hypoxic respiratory failure, requiring 10L <strong>of</strong><br />

oxygen via nasal cannula and eventually an oximizer. After continued supportive treatment and<br />

appropriate antibiotic therapy, his symptoms improved. He was eventually transitioned to oral<br />

antibiotics and completed a treatment duration <strong>of</strong> 6 weeks.<br />

DISCUSSION: This case illustrates a potential serious complication <strong>of</strong> a relatively simple condition,<br />

tonsillitis. Although a rare complication, Lemierre’s Syndrome is associated with common conditions<br />

seen by many primary care physicians. It is characterized by septic thrombophlebitis and bacteremia,<br />

and <strong>of</strong>ten follows common oropharyngeal infections such as tonsillitis and dental infections. It is most<br />

commonly associated with the bacteria Fusobacterium necrophorum and can cause serious<br />

complications, such as septic pulmonary emboli, leading to hypoxemia and respiratory failure. With the<br />

potential for such significant sequelae, it is imperative, therefore, that primary care physicians keep this<br />

diagnosis in mind when evaluating patients that present with more systemic and severe symptoms<br />

following an initial presentation with what may seem like a simple sore throat.<br />

An Atypical Case <strong>of</strong> Acute Pericarditis<br />

Nathan Richards, MD Second Author: William Edwards, MD Co-Author: Brad Keith, MD<br />

INTRODUCTION: Learning Objectives:<br />

1) Discuss clinical presentation and diagnostic evaluation <strong>of</strong> acute pericarditis<br />

2) Discuss etiologies <strong>of</strong> acute pericarditis with specific discussion mesalamine induced pericarditis<br />

3) Discuss treatment and prognosis <strong>of</strong> acute pericarditis<br />

CASE PRESENTATION: 28 y/o female with past medical history significant for recently diagnosed<br />

ulcerative colitis who presented to the ED twice over 1 week period for recurrent left sided chest pain.<br />

Her pain was described as a 10/10 sharp sensation, sudden in onset, worse when supine, and improved<br />

with leaning forward. The pain radiated to her left scapula. Her physical exam was only remarkable for<br />

tachycardia and no murmurs or rubs were present. On presentation the patient had an EKG revealing<br />

diffuse ST elevations. Work-up revealed RF, ANA, ANCA negative; HIV1/HIV2 negative; CMV negative;<br />

Hgb was 7.4 with MCV <strong>of</strong> 70; Fe 8.0; Transferrin 168; Fe/TIBC %saturation 3%; Hgb variants normal. An<br />

ECHO demonstrated a small to moderate circumferential pericardial effusion. The patient was again<br />

given the diagnosis <strong>of</strong> acute pericarditis and continued on colchicine and Ibupr<strong>of</strong>en. Mesalamine was<br />

restarted 3 weeks prior to symptoms and the dose was increased 1 week prior from 3.6grams to 4.8<br />

grams. In literature review, mesalamine has been reported to be a rare cause <strong>of</strong> pericarditis, and this<br />

was felt to be the culprit given the recurrence <strong>of</strong> her symptoms.<br />

DISCUSSION: Acute pericarditis is an inflammation <strong>of</strong> the pericardial sac and <strong>of</strong>ten adjacent<br />

myocardium. Chest pain is the predominate feature, classically presenting as sudden, sharp retrosternal<br />

or left sided chest pain <strong>of</strong>ten radiating to the back. The pain is usually exacerbated in the supine position<br />

and partially relieved when leaning forward. Physical exam may reveal a pathognomonic pericardial<br />

friction rub, but is <strong>of</strong>ten unrevealing. Serial EKGs are <strong>of</strong>ten obtained showing an evolution <strong>of</strong> signs, <strong>of</strong><br />

which, only stage 1 is specific for pericarditis demonstrating diffuse ST-segment elevations with PR<br />

depression. Echocardiography may reveal a small pericardial effusion. The cause is usually not identified<br />

but most cases are thought to be viral in origin. Other etiologies to consider are uremia, post myocardial<br />

infarction, collagen vascular disease, cancer, and drug induced. The list <strong>of</strong> medications that have been<br />

associated with pericarditis is extensive but includes procainamide, hydralazine, amiodarone, Isoniazid,<br />

Penicillin, cyclophosphamide, and mesalamine. The disease is usually self-limited and typically responds<br />

well to NSAIDs, with a common regimen being ibupr<strong>of</strong>en 400-800mg Q8 hours for 2 weeks. Colchicine<br />

may also be beneficial especially in cases <strong>of</strong> recurrent pericarditis. Mesalamine induced pericarditis is a<br />

rare phenomenon but there have been multiple case reports <strong>of</strong> recurrent myopericarditis in the setting<br />

<strong>of</strong> mesalamine use which resolved completely once the medication was stopped.<br />

Hyperhemolysis Syndrome in a patient with Adenocarcinoma <strong>of</strong> the colon.<br />

Khan, Muhammad. Ghanta, Bhargavi. Darabi, Kamran.<br />

INTRODUCTION: Delayed hemolytic transfusion reaction (DHTR), is a well known complication <strong>of</strong><br />

transfusion therapy. Occasionally, native red cell hemolysis can be implicated in DHTR resulting in lower<br />

post transfusion hemoglobin than pre transfusion. This condition, termed as hyperhemolysis syndrome,<br />

is more common among patients with sickle cell disease and thalassemia. The occurrence <strong>of</strong> this<br />

syndrome in patients without underlying hemoglobinopathies is rare.<br />

CASE PRESENTATION: A 74 yr old female with prior history <strong>of</strong> colonic adenocarcinoma presented to a<br />

local hospital with diarrhea. She was found to be anemic with hemoglobin <strong>of</strong> 8.4 g/dl. Her blood group<br />

was A negative and she received 2 units <strong>of</strong> cross matched red blood cells after a negative antibody<br />

screen. She returned to the hospital 12 days later with lethargy and fatigue and was found to be anemic<br />

with hemoglobin <strong>of</strong> 7.8 g/dl. Antibody screen was positive for Anti-K antibody. Hemolysis persisted<br />

despite receiving K antigen negative red blood cells and twice during the following 30 day period, her<br />

hemoglobin decreased to a level lower than her initial value. No source <strong>of</strong> bleeding could be identified<br />

and a normal hemoglobin electrophoresis was noted. She responded well to 4 weeks <strong>of</strong> oral prednisone<br />

with no further hemolysis after discontinuation <strong>of</strong> therapy.<br />

DISCUSSION: Hyperhemolysis syndrome can occur in patients with no underlying hemoglobinopathies<br />

and oral prednisone is an effective treatment.<br />

"NOT QUITE an ACUTE ST-SEGMENT ELEVATION MI"<br />

Ahmad Alazzeh MD; Venkat Gangadharan MD; Terry Forrest MD FACC; Clarence Spannuth JR MD ;<br />

INTRODUCTION:Acute Myocardial Infarction is one <strong>of</strong> the most serious emergencies physicians face on<br />

a daily basis. The typical presentation includes chest pain with classic EKG changes and positive<br />

TROPONIN level. However, rarely with these findings there is an alternative etiology<br />

CASE PRESENTATION: A 58 year old man presented to the ER with complaints <strong>of</strong> worsening chest pain.<br />

His past medical history included a previous myocardial infarction, and diffuse large B cell lymphoma<br />

treated with 6 cycles <strong>of</strong> R-CHOP with remission. Physical Exam revealed a patient in moderate distress<br />

secondary to chest pain, slightly elevated blood pressure and HR, right testicular swelling, but no chest<br />

wall tenderness. labs revealed a normal CBC and BMP, but marginally elevated troponin I (1.3).<br />

Subsequent EKGs demonstrated 1-2 mm concave ST elevation. With chest pain, history <strong>of</strong> anteroseptal<br />

MI, and other risk factors for CAD including family history and tobacco abuse. Patient was evaluated by<br />

left heart catheterization, which revealed mild nonobstructive coronary artery disease. With these<br />

results, possible anterior ST elevation MI was ruled out and further investigations were carried out<br />

including a Transthoracic ECHO demonstrated a unique finding <strong>of</strong> pr<strong>of</strong>ound anteroseptal wall thickening<br />

resulting in near obliteration <strong>of</strong> the left ventricular cavity with marked reduction in LV function. CHEST<br />

CT revealed multiple enlarged mediastinal lymph nodes suggestive <strong>of</strong> a recurrence <strong>of</strong> his previous Non-<br />

Hodgkins Lymphoma. With his clinical picture and radiological findings the likely etiology <strong>of</strong> his chest<br />

pain, elevated troponin and evolving EKG changes were attributed to secondary cardiac lymphoma – a<br />

rare manifestation.<br />

DISCUSSION: Metastatic involvement <strong>of</strong> the heart is more common cause <strong>of</strong> cardiac malignancies;<br />

therefore cardiac or pericardial metastasis should be considered whenever a patient with a known<br />

malignancy develops cardiovascular symptoms. Malignant melanoma, leukemia, lymphoma, lung and<br />

breast cancers are most commonly associated with cardiac involvement. Most cases <strong>of</strong> cardiac<br />

lymphoma demonstrate either one or more chamber involvement with the right heart being the most<br />

common site. Hypertrophy or thickening <strong>of</strong> the ventricular septum, can result in characteristic<br />

hemodynamic disturbances. Clinical symptoms <strong>of</strong> cardiac lymphoma are nonspecific ranging from being<br />

silent (as seen in B cell lymphomas ) to producing chest pain, worsening shortness <strong>of</strong> breath,<br />

palpitations etc. Physical signs may include a pericardial friction rub; distended neck veins or even signs<br />

<strong>of</strong> heart failure. Diagnostic evaluation should mainly include echocardiography, MRI and CT. Most <strong>of</strong>ten,<br />

however, conclusive diagnosis via tissue sampling is usually obtained on post-mortem<br />

examination. Conclusion: Cardiac Lymphoma, albeit a rare disease, can mimic acute ST-Elevation<br />

Myocardial Infarcation. Early detection and treatment <strong>of</strong> Cardiac Lymphoma in cases <strong>of</strong> recurrent Non-<br />

Hodgkin Lymphoma is imperative to prevent serious complications such as outflow obstruction and to<br />

develop therapeutic regimens in the future<br />

Acute Psychosis in a Patient with Cushing's Disease<br />

Matthew Erickson Edwards, DO Mark Rasnake, MD, FACP Daphne Norwood, MD, FACP<br />

INTRODUCTION: Cushing’s syndrome is a rare endocrine disorder that causes increased secretion <strong>of</strong><br />

cortisol through disruption <strong>of</strong> the hypothalamic-pituitary-adrenal axis. This occurs in either an<br />

adrenocorticotropic hormone (ACTH) dependent or ACTH-independent mechanism. Cushing’s syndrome<br />

impacts multiple organ systems and can have a variety <strong>of</strong> manifestations. Acute psychosis is a less<br />

common but documented manifestation <strong>of</strong> Cushing’s syndrome.<br />

CASE PRESENTATION: A 57-year-old Caucasian male presented as a direct admit to the impatient<br />

service from his primary care <strong>of</strong>fice with acute psychosis and delirium. He was a successful, high<br />

functioning individual until he began experiencing spells <strong>of</strong> paranoia, hallucinations, hyper-sexuality, and<br />

seizure-like activity over the previous 3 weeks. The episodes were increasing in frequency and<br />

severity. He had been diagnosed with Cushing’ syndrome two years prior and the exact etiology had not<br />

been identified. He was undergoing treatment with metyrapone. There was no history <strong>of</strong> substance<br />

abuse or psychiatric illness.<br />

Vital signs revealed the following: temperature 98.0°F, BP 142/90 mmHg, HR 66, RR 20, and<br />

oxygen saturation 95%. Physical exam was notable for findings characteristic <strong>of</strong> Cushing’s syndrome.<br />

Neurologically he had no focal deficits and was alert and oriented to person, place, and time. Psychiatric<br />

evaluation revealed paranoid and grandiose thoughts with no intention to harm others or self.<br />

Extensive serological studies were remarkable for mildly elevated prolactin and chromogramin A<br />

levels. Cortisol level was normal, however outpatient records indicated recent elevation, as well as ACTH<br />

elevation. Toxicology screen was negative. CT and MRI <strong>of</strong> the head and neck were notable for a stable<br />

right frontal lobe cavernous malformation. CT <strong>of</strong> the chest, abdomen, and pelvis was negative for any<br />

significant abnormality. EEG demonstrated no signs <strong>of</strong> epileptiform activity.<br />

After exclusion <strong>of</strong> other causes, it was thought that his acute psychosis could be a manifestation<br />

<strong>of</strong> Cushing’s syndrome. He was started on antipsychotics for symptom management and referred to an<br />

outside facility for further evaluation including inferior petrosal vein sampling and pituitary MRI. This<br />

revealed a pituitary adenoma secreting ACTH, specifying this as Cushing’s disease, and resection <strong>of</strong> this<br />

lesion is pending. He is still experiencing episodes <strong>of</strong> abnormal behavior but is hopeful surgery will be<br />

curative.<br />

DISCUSSION: The neuropsychiatric manifestations <strong>of</strong> Cushing’s are less common but nonetheless<br />

debilitating. The severity can range from anxiety to psychosis, with major depression being the most<br />

common manifestation. Previous case reports note that the neuropsychiatric complications <strong>of</strong> Cushing’s<br />

improve with treatment but some patients never return to baseline function.<br />

SHAKY HEART CAN PRESENT AS SHAKY LIMB<br />

Hetvi K Joshi, MD Second Author: Nathaniel Whaley MD Third Author: Mihir Patel MD<br />

INTRODUCTION:Transient Ischemic Attack (TIA)and stroke not uncommonly occurs secondary to focal<br />

cerebral hypoperfusion in the context <strong>of</strong> relative hypotension distal to an extra or intracranial artery<br />

stenosis.In this report,we document a case <strong>of</strong> an unusual presentation <strong>of</strong> TIA known as a shaky limb TIA<br />

in the context <strong>of</strong> carotid occlusion and decreased ejection fraction(EF)secondary to symptomatic<br />

advanced coronary artery disease(CAD).<br />

CASE PRESENTATION: A 57 Year old male presented with chest pain and recurrent left hemianesthesia<br />

who described 3 month history <strong>of</strong> near weekly episodes <strong>of</strong> brief transient left arm and leg involuntary<br />

jerking, shaking with retained awareness that occurred only with standing and <strong>of</strong>ten resulted in a fall. He<br />

had a history <strong>of</strong> recurrent right middle cerebral artery (MCA)territory ischemic stroke,total right internal<br />

artery carotid (ICA) occlusion and an extensive history <strong>of</strong> CAD status post coronary artery bypass graft<br />

(CABG) with EF <strong>of</strong> 15 %. Computed tomography (CT) angiogram <strong>of</strong> the extra cranial vessels confirmed<br />

total occlusion <strong>of</strong> the right ICA and 70% stenosis <strong>of</strong> right vertebral artery.A CT head showed evidence <strong>of</strong><br />

old right frontal and parietal lobar strokes.The individual was taken for cardiac catheterization which<br />

confirmed an occluded graft to the left anterior descending and severe native multi-vessel CAD. He<br />

underwent percutaneous coronary intervention(PCI)for the same.After that chest pain and shaky limb<br />

symptoms resolved.<br />

DISCUSSION: Limb shaking TIA is rare phenomenon.It is likely under recognized by primary care<br />

physicians because <strong>of</strong> its positive symptomatology (i.e. increase in movement) whereas stroke or TIA is<br />

most commonly associated with negative symptoms (i.e. loss <strong>of</strong> function).The mechanism behind this,is<br />

transient hypoperfusion <strong>of</strong> the motor areas <strong>of</strong> the cerebrum(i.e. precentral gyrus) usually in the context<br />

<strong>of</strong> relative hypotension in the setting <strong>of</strong> an ICA stenosis resulting in partial dysfunction making the limb<br />

shake.The principal <strong>of</strong> management is to avoid hypotension and increase perfusion to the ischemic<br />

area.In this case,cardiac intervention was performed in an attempt to increase the cardiac EF and to<br />

optimize the individual’s medical management in order to avoid hypotension. If these measures prove<br />

ineffective,an extracranial-intracranial bypass may be considered.<br />

Infected Left Atrial Myxoma, a Rare Cause <strong>of</strong> Bacteremia with a Common Pathogen<br />

Adrianne C Netterville, MD Second Author: Mark S Rasnake, MD<br />

INTRODUCTION: Bacteremia due to methicillin resistant Staphylococcus aureus (MRSA) is very<br />

common, but rarely is the etiology from an infected left atrial myxoma. Myxomas are the most common<br />

primary cardiac tumor. Uninfected myxomas <strong>of</strong>ten mimic endocarditis clinically and large vegetations<br />

from endocarditis have been known to mimic myxomas. Infected myxomas themselves are quite rare<br />

however. If presented with persistent positive blood cultures or fever <strong>of</strong> unknown origin, a patient<br />

should always be evaluated with echocardiography to rule out endocarditis or, as in our case an infected<br />

myxoma.<br />

CASE PRESENTATION: A 68- year-old male originally was admitted to an outside hospital to undergo<br />

an elective left hip arthroplasty. Subsequently, his post operative course was complicated by ileus and<br />

hematochezia. He underwent an EGD, which showed gastritis. He gradually improved postoperatively<br />

and was transferred to a rehabilitation facility. He continued to improve at the rehab hospital until he<br />

spiked a fever and was found to have 2/2 blood cultures positive for MRSA. Vancomycin was initiated.<br />

On day ten <strong>of</strong> antibiotics, he developed another fever and was again found to have 2/2 blood cultures<br />

positive for MRSA. Vancomycin was switched to linezolid. Transesophageal echocardiogram suggested<br />

vegetations and he was therefore transferred to our facility for surgical evaluation. Repeat<br />

echocardiogram showed a left atrial mass adherent to the interatrial septum. He then underwent<br />

robotically assisted removal <strong>of</strong> the left atrial mass. While in the operating room, they performed frozen<br />

sections which were microscopically and grossly consistent with a myxoma. A calretinin immunostatin<br />

was performed and highlighted the myxoma cells. Following surgery repeat blood cultures showed no<br />

growth. He was treated with a six week course <strong>of</strong> daptomycin and was well at his two month follow up<br />

visit.<br />

DISCUSSION: This case illustrated an unusual cause <strong>of</strong> persistent bacteremia. Infected myxomas are an<br />

extremely rare entity. The most common presentations mimic infective endocarditis with fatigue,<br />

malaise, and weight loss. Fevers are also common even in uninfected myxomas. Embolization with<br />

uninfected atrial myxomas is very common, although once infected, the incidence <strong>of</strong> cerebral and<br />

systemic embolization is much higher. The most common cause <strong>of</strong> infected atrial myxomas is dental<br />

work. In our patient, it is believed to have become infected via bacteremic seeding during prior hip<br />

arthroplasty.<br />

Evaluation should include echocardiography and prompt surgical resection in order to reduce the<br />

chances <strong>of</strong> embolization or cardiovascular complications, including sudden death. Patients should also<br />

undergo annual surveillance with echocardiography, to monitor for recurrence.<br />

INTRODUCTION: Colon cancer is the most common gastro-intestinal malignancy. It is the third most<br />

common form <strong>of</strong> cancer and second leading cause <strong>of</strong> death among cancers worldwide. Colon cancer<br />

commonly presents as bleeding, ill-defined abdominal pain, altered bowel habits or intestinal<br />

obstruction. It rarely presents as Psoas abscess. Diagnosis remains difficult, especially when it is the first<br />

sign <strong>of</strong> colon cancer. We report a case <strong>of</strong> colon adenocarcinoma presenting as Psoas abscess.<br />

CASE PRESENTATION: A 65 years old woman presented with swelling and erythema over right gluteal<br />

region 48 hours after intramuscular injection <strong>of</strong> Ketorolac for arthritic hip joint pain. She also<br />

complained <strong>of</strong> constipation with abdominal discomfort for two weeks. She had induration over the right<br />

gluteal region with diffusely tender abdomen. Laboratory data showed leukocytosis, elevated ESR, Hg <strong>of</strong><br />

9.3gm%, low MCV at 76fl and low ferritin at 15ng/ml. Stool hem-occult was negative. Ultrasound <strong>of</strong><br />

abdomen and right buttock demonstrated extensive edema without distinct abscess in gluteal region.<br />

Empiric antibiotics were started. After two days, purulent discharge was noted from right gluteal region.<br />

Computed Tomography (CT) <strong>of</strong> abdomen and pelvis showed right psoas abscess with air pockets.<br />

Surgical debridement was performed. Wound culture grew E. coli and anaerobes. Biopsy <strong>of</strong> the abscess<br />

wall showed necrotic tissue with no evidence <strong>of</strong> malignancy. Her course was further complicated with<br />

venous thrombo-embolism (VTE), for which heparin was started. She developed hematochezia while on<br />

heparin. Gluteal wound failed to heal and repeat CT showed persistent retroperitoneal abscess<br />

extending up to right groin with thickened cecal wall. She underwent another exploration <strong>of</strong> local area<br />

with debridement. Right groin had necrotic lymph node on exploration. Excisional biopsy showed<br />

adenocarcinoma believed to be <strong>of</strong> colon origin. On colonoscopy a large multi-lobulated cecal mass was<br />

found and biopsied. Moderately differentiated adenocarcinoma <strong>of</strong> colon was confirmed on pathology.<br />

Patient underwent right hemicolectomy and adjuvant chemotherapy was initiated.<br />

DISCUSSION: Colon adenocarcinoma is one <strong>of</strong> the few preventable and curable cancers if detected and<br />

treated in time. Psoas abscess is a rare presentation <strong>of</strong> colon adenocarcinoma. There are very few<br />

reported cases in literature which suggest colon cancer as possible etiology in unexplained psoas<br />

abscess. It is very likely that colon cancer was already present in our patient at the initial presentation <strong>of</strong><br />

the psoas abscess. Presence <strong>of</strong> iron deficiency anemia, constipation and abdominal discomfort in our<br />

patient could have led us to consider colonoscopy at early stage but co-incidental history <strong>of</strong><br />

intramuscular injection prior to onset <strong>of</strong> symptoms clouded the diagnosis initially. However, failed<br />

response to treatment, repeat CT scan findings and tissue biopsy guided us towards colonoscopy, which<br />

confirmed the diagnosis. In Conclusion, our case highlights the importance <strong>of</strong> considering underlying<br />

colon cancer in patients with psoas abscess and colonoscopy should be considered at early stage to<br />

resolve the diagnostic dilemma.<br />

Idiopathic Pulmonary Fibrosis, Or Something More? What Families Teach Us About The Disease.<br />

Devon Paul, MD<br />

INTRODUCTION: Idiopathic pulmonary fibrosis (IPF) is an interstitial lung disease (ILD) characterized by<br />

replacement <strong>of</strong> normal lung parenchyma with fibrotic tissue, leading to respiratory failure in half <strong>of</strong><br />

patients within three to five years <strong>of</strong> diagnosis. It has an estimated prevalence <strong>of</strong> 42 cases per 100,000<br />

people in the US. The disease progresses at variable intervals, is ultimately fatal, and has no effective<br />

medical treatment. Recent advancements in IPF research have led to the discovery that a significant<br />

proportion <strong>of</strong> cases are familial. In studying familial IPF cohorts, multiple gene mutations<br />

have been identified linking IPF to other inheritable diseases, providing insights into the pathogenesis <strong>of</strong><br />

the disease while <strong>of</strong>fering potential targets for therapy.<br />

CASE PRESENTATION: A 61 year old male presented to his primary care physician at the urging <strong>of</strong> his<br />

family complaining <strong>of</strong> dyspnea with exertion. He had an extensive family history <strong>of</strong> IPF. He was referred<br />

to a pulmonologist, where he underwent pulmonary function testing (PFT) which showed restrictive<br />

lung disease and decreased diffusion capacity (DLCO). A high-resolution computed tomography (HRCT)<br />

scan <strong>of</strong> his chest showed bibasilar fibrosis with honeycombing in a usual interstitial pneumonia<br />

pattern. He was diagnosed with IPF and referred to a tertiary medical facility, where he was enrolled in<br />

a phase three clinical trial. Since his diagnosis <strong>of</strong> IPF, his daughter has also been screened, and was<br />

found to have early pulmonary fibrosis on HRCT in addition to known leukopenia and anemia. Detailed<br />

family history revealed multiple maternal family members with IPF, cryptogenic cirrhosis, or<br />

myeloproliferative disease. Given his pedigree, he and his daughter have both agreed to genetic testing<br />

to see if their family possesses a known familial IPF gene mutation.<br />

DISCUSSION: This patient's case illustrates key points about IPF pertinent to the general internist. First<br />

is the recognition that the disease is more common that originally believed. Many primary care<br />

physicians will have IPF patients in their clinic at some point in their careers. Second, up to 20% <strong>of</strong> IPF<br />

cases are familial. For the primary care physician seeing family members <strong>of</strong> IPF patients, knowing this<br />

association is critical. Third, among familial IPF cases, several genetic mutations have already been<br />

identified. The most significant <strong>of</strong> these are the TERT and TERC mutations in the telomerase complex,<br />

found in approximately 15% <strong>of</strong> familial IPF cases. Families with these mutations <strong>of</strong>ten exhibit a<br />

spectrum <strong>of</strong> disease including IPF, myelodysplastic syndrome, aplastic anemia, cirrhosis, and<br />

dyskeratosis congenita. The multidisciplinary nature <strong>of</strong> internal medicine allows internists to identify<br />

linkages between disorders such as these in disparate organ systems, and will be critical as more cases<br />

<strong>of</strong> IPF are discovered.<br />

Dysphagia – Roots Laid in Coronaries !!!<br />

Tejas Vinodbhai Raiyani, MD Co Author: Pranav Patel, MD Co Author: Vijay Ramu, MD<br />

INTRODUCTION: Dysphagia has been a common symptom related to upper gastrointestinal system. It<br />

has rarely been reported related to cardiovascular system. Coronary Artery Disease (CAD) causing<br />

dysphagia has not been reported in the literature. We report a case <strong>of</strong> severe multi-vessel CAD that<br />

presented as dysphagia which resolved completely after Coronary Artery Bypass Grafting (CABG)<br />

procedure.<br />

CASE PRESENTATION: A 80-year-old woman with history <strong>of</strong> dyslipidemia presented with difficulty to<br />

swallow solids and liquids on and <strong>of</strong>f for one year with gradual worsening since last 1 month. She<br />

reported sensation <strong>of</strong> food getting stuck in the chest but denied any regurgitation or vomiting. She<br />

denied for chest pain or shortness <strong>of</strong> breath. Physical examination and initial laboratory data were<br />

unremarkable. Patient had EGD and colonoscopy before 6 months, which were normal. Biopsies from<br />

the esophagus were negative for eosinophilic esophagitis. Her barium esophagogram including 13mm<br />

barium pill swallow was also normal. Patient was further investigated for CAD in the light <strong>of</strong> negative<br />

work up for any gastrointestinal disorder. Though she had negative exercise nuclear stress test, elective<br />

Left heart catheterization was pursued. It revealed severe CAD reported as “left main equivalent”<br />

disease involving proximal LAD, first Ramus Intermedius ostium and proximal first Obtuse Marginal in<br />

the Left Circumflex system. On echocardiogram, ejection fraction was preserved at 62% with grade 1<br />

diastolic dysfunction. She underwent triple vessels CABG. Surprisingly, her dysphagia symptoms resolved<br />

completely after postoperative recovery.<br />

DISCUSSION: Dysphagia has been reported in the literature as the cause <strong>of</strong> cardiovascular disease due<br />

to external mechanical compression from the great vessels in form <strong>of</strong> Dysphagia Aortica and Lusoria.<br />

Valvular heart disease can also cause dysphagia secondary to left atrial enlargement. It has not been<br />

reported as a presenting symptom <strong>of</strong> CAD. CAD typically presents with chest pain or angina pectoris on<br />

physical exertion that may spread to the left arm or the neck, back, throat, or jaw. Atypical symptoms<br />

include (but not limited to) back, neck, or jaw pain, nausea, vomiting, indigestion, weakness, fatigue,<br />

dizziness, light-headedness. Other Known presentations <strong>of</strong> CAD include angina with atypical features,<br />

exertional dyspnea alone, myocardial infarction, cardiac failure, arrhythmias, sudden cardiac death or<br />

uncommonly with fatigue, stroke or thromboembolic events. In our case, upper GI workup was normal<br />

for dysphagia, hence cardiac investigations were considered. Left heart catheterization revealed severe<br />

CAD which was then treated with CABG. Post-operatively, her dysphagia symptoms resolved completely.<br />

In conclusion, this case suggests us to consider work up for ischemic heart disease where dysphagia has<br />

unidentified cause <strong>of</strong> origin. It could be a step to defuse the ticking bomb in time.<br />

A RARE CASE OF PARADOXICAL RENAL EMBOLUS THROUGH PATENT FORAMEN OVALE<br />

Gaurav S Shah Second authors: Bhavesh B Barad, Parag A Brahmbhatt, Laura Farrington, Koyamangalath<br />

Krishnan<br />

INTRODUCTION: Isolated paradoxical renal embolism has been reported very rarely in literature. We<br />

report a case <strong>of</strong> paradoxical unilateral renal embolus due to patent foramen ovale (PFO) in an otherwise<br />

healthy Caucasian female.<br />

CASE PRESENTATION: A 42 year old Caucasian female was admitted to the hospital due to severe flank<br />

pain associated with nausea and vomiting for 4 days. Computed Tomography (CT) <strong>of</strong> abdomen without<br />

contrast done 2 days ago was without any abnormalities. Medical history was significant for<br />

hypothyroidism and migraine. She was taking Armour thyroid, oral contraceptives and topiramate. On<br />

examination she had flank and left lower quadrant abdominal tenderness. Labs showed normal<br />

electrolytes, renal function and benign urinalysis. There was leukocytosis (14.7) without any other<br />

evidence <strong>of</strong> infection. CT abdomen with contrast was done and showed left renal infarction.<br />

Hypercoagulable work up was ordered while patient was started on heparin and warfarin and later on<br />

warfarin alone after adequate bridging. Subsequently lower extremity venous doppler was done, which<br />

was negative for Deep Venous Thrombosis. Echocardiogram with bubble study was ordered which<br />

showed patent foramen ovale (PFO) with significant right to left shunt. Renal artery angiography was<br />

done which ruled out local causes like fibromuscular dysplasia, aneurysm or dissection. While awaiting<br />

hypercoagulable work up results, closure <strong>of</strong> PFO was performed. Patient was later discharged on<br />

warfarin with follow up as outpatient in 1 week. On follow-up, patient was asymptomatic with<br />

hypercoagulable workup negative, hence warfarin was discontinued.<br />

DISCUSSION: Paradoxical emboli due to PFO are known to result in cryptogenic stroke, but it’s rarely<br />

reported to cause renal infarction. Cases reported show that patients with PFO have higher incidence <strong>of</strong><br />

paradoxical emboli not only due to preformed thrombus, but also in some instances due to certain<br />

thrombogenic chemicals which are thought to get metabolized in lungs. Studies have reported increased<br />

incidence <strong>of</strong> re-embolization in patients with unrepaired PFO who already have suffered from embolic<br />

event. Repair <strong>of</strong> PFO in such individuals results in considerable symptomatic improvement as well as<br />

marked reduction in incidence <strong>of</strong> further paradoxical embolus. We advise clinicians to have high index <strong>of</strong><br />

suspicion to consider the diagnosis <strong>of</strong> renal infarction secondary to paradoxical embolus in a patient<br />

with history <strong>of</strong> PFO in appropriate setting. Proper diagnosis and timely treatment can significantly<br />

reduce morbidity as well as serious complication like myocardial infarction, stroke, transient ischemic<br />

attack and limb ischemia. Further research about possible thrombogenic chemicals which may be<br />

metabolized in lungs and results in increased incidence <strong>of</strong> paradoxical emboli formation should be<br />

considered.<br />

SECONDARY HYPERPARATHYROIDISM IN METASTATIC PROSTATE CANCER: A NEW SYNDROME?<br />

Gaurav S Shah Second Author: Bhavesh B Barad, Alan N Peiris, Parag A Brahmbhatt<br />

INTRODUCTION: Secondary hyperparathyroidism is well recognized in renal insufficiency and vitamin<br />

deficiency. Rarely, certain malignancies with metastatic involvement <strong>of</strong> bone such as breast and<br />

prostate cancer can be associated with hypocalcemia. We report a case <strong>of</strong> elevated parathyroid<br />

hormone (PTH) in the presence <strong>of</strong> a normal ionized calcium, normal renal function and vitamin D in a<br />

patient with metastatic prostate cancer.<br />

CASE PRESENTATION: A 77 year old Caucasian male was referred to endocrine clinic because <strong>of</strong> an<br />

elevated PTH level. On presentation he was feeling weak, nauseated and had a 29 lb weight loss over<br />

the last 2-3 months. He also had a history <strong>of</strong> colon cancer treated with a partial colectomy about 22<br />

years ago, hyperlipidemia and prostate cancer. His only medications were Finasteride and Simvastatin.<br />

His initial diagnosis <strong>of</strong> prostate adenocarcinoma was in 1995. Various treatment modalities were tried<br />

including brachytherapy, radiation and chemotherapy. No abnormal physical findings were noted.<br />

Recent bone scan was strongly suspicious for interval development <strong>of</strong> widespread skeletal metastatic<br />

disease, likely related to prostate cancer. His PSA was 386.52(Normal 0-4.0] and alkaline phosphatase<br />

was 274 [Normal 38-126] which were consistent with metastatic prostate cancer. Treatment with<br />

calcium, Vitamin D followed by bisphosphonates resulted in a dramatic improvement in wellbeing, near<br />

normalization <strong>of</strong> PTH levels (64/71) and a reduction in alkaline phosphatase (236). However, PSA level<br />

increased (429).<br />

DISCUSSION: We believe that secondary hyperparathyroidism in prostate cancer is underestimated<br />

and likely has multiple etiologies including the presence <strong>of</strong> vitamin D deficiency and perhaps renal<br />

impairment. However, in our patient another etiology could well be the incorporation <strong>of</strong> calcium into<br />

osteoblastic metastases, resulting in PTH elevation secondary to the fall in ionized calcium. We believe<br />

that failure to recognize this syndrome may lead to hypocalcemia related to hungry bone syndrome. An<br />

elevated PTH value per se has been linked to a variety <strong>of</strong> adverse health outcomes including enhanced<br />

mortality. Our patient responded very well to treatment with calcium (1500 mg daily) and vitamin D<br />

(4000 iu D3) followed by bisphosphonates. However, the rise in PSA is concerning and the optimal<br />

treatment for this condition including the role <strong>of</strong> calcium, vitamin D and bisphosphonates among other<br />

agents need additional studies. However, initial treatment with calcium and vitamin D has the benefit <strong>of</strong><br />

improving wellbeing and possibly reducing the side-effects <strong>of</strong> bisphosphonates. Providers managing<br />

patients with prostate cancer should be cognizant <strong>of</strong> this phenomenon and check PTH values especially<br />

in the presence <strong>of</strong> metastases either radiologically or in the presence <strong>of</strong> elevated alkaline phosphatase<br />

values. The use <strong>of</strong> bisphosphonates should be made after these considerations are weighed.<br />

Gastric Bypass: Lowering more than weight<br />

Michael McNeal MD, Shannon Ward DO, Maybelline Lezama MD<br />

INTRODUCTION: Gastric bypass surgery <strong>of</strong>fers significant weight loss and is a powerful tool to fight<br />

obesity and its related adverse health conditions, but it is not without complications. Many physicians<br />

are aware <strong>of</strong> the common complications. However, gastric bypass has recently been implicated in<br />

noninsulinoma pancreatogenous hypoglycemia, a rare but significant side effect which can occur even<br />

years after surgery.<br />

CASE PRESENTATION: A 46 year-old white female eight years post gastric bypass surgery presented to<br />

our hospital with recurrent pancreatitis. During her recovery, she began to experience postprandial<br />

hypoglycemia with blood glucose levels in the 20s-30s. Laboratory values were checked during one such<br />

event revealing a glucose <strong>of</strong> 23, elevated c-peptide, no insulin antibodies, and an insulin level in the<br />

normal range with a negative hypoglycemic agent screen. Imaging did not reveal a pancreatic mass. A<br />

selective arterial calcium stimulation test was consistent with non-insulinoma hyperinsulinemic<br />

hypoglycemia. She was started on a low to no carbohydrate, high protein, and high fat diet with 6 meals<br />

per day with complete resolution <strong>of</strong> her hypoglycemia.<br />

DISCUSSION: Beta-cell hypertrophy following gastric bypass surgery represents a rare but troubling<br />

complication for those affected. The mechanism for this process has not yet been established, but one<br />

postulated mechanism involves stimulation <strong>of</strong> beta cell growth from gut hormones that happens over<br />

time. Gastric bypass can cause rapid delivery <strong>of</strong> stomach contents to the distal ileum resulting in<br />

elevated levels <strong>of</strong> glucagon-like peptide 1, which has been shown to increase beta cell mass in rodents<br />

and decrease islet cell apoptosis in humans. The true mechanism warrants further study because <strong>of</strong> the<br />

possibility it holds not only for treatment <strong>of</strong> these patients but it may represent future targets in<br />

diabetic management.<br />

Contagion From Horse to human: Streptococcus Equi Bacteremia in a Horse Lover<br />

Linh Lu, Barbara Atkinson, Saji Pillai, Aldon Li<br />

INTRODUCTION: A 51 year-old Caucasian female with Diabetes Type 1, coronary disease, and splenic<br />

atrophy was hospitalized for chest pain and fevers. Her initial emergency room visit was inconclusive for<br />

a source and dismissed home. The patient continued to have two weeks <strong>of</strong> intermittent fevers and<br />

returned to the hospital with fatigue, night sweats, nausea and vomiting associated with left substernal<br />

chest pain radiating to her left jaw and arm. She denied acute fever, sick contacts, travel or recent<br />

illness. She reportedly received all childhood and adult immunizations, including influenza,<br />

Pneumococcal, and Haemophilus influenza type b, tetanus and meningococcal vaccines. As a hobby, she<br />

feeds, cleans, and rides horses complicated by multiple scratches on her upper extremities. She denied<br />

recent encounters with sick horses.<br />

CASE PRESENTATION: Physical examination revealed a non-toxic female that was unremarkable other<br />

than a non-radiating 2/6 systolic murmur in the left sternal border and multiple healed excoriations on<br />

both arms. She had a temperature <strong>of</strong> 102.8 o F on admission. The fevers waxed and waned during<br />

hospitalization with the highest temperatures recorded in the evening hours.<br />

Cardiovascular workup including transthoracic echocardiogram were unremarkable. Diagnostic<br />

laboratory exam was normal except for a leukocytosis <strong>of</strong> 25.9 k/mm3, bandemia <strong>of</strong> 9%, C-reactive<br />

protein <strong>of</strong> 81.6 mg/L and two blood cultures grew Streptococcus equi. Her chest discomfort, fevers,<br />

weakness, and leukocytosis resolved with intravenous penicillin.<br />

DISCUSSION: Streptococcus equi is a Group C Streptococci bacterium that most commonly causes<br />

strangles infection in horses. Equine strangles leads to lymphadenopathy, respiratory distress and<br />

death. It is an unusual zoonotic infection with only a handful <strong>of</strong> reported cases <strong>of</strong> equine-to-human<br />

transmission. The patient’s immunocompromised state <strong>of</strong> splenic atrophy and diabetes mellitus<br />

coupled with handling horses likely contributed to her susceptibility to this bacteremia. She was<br />

counseled to limit contact with horses, avoid consumption <strong>of</strong> unpasteurized foods, continuation <strong>of</strong> oral<br />

Penicillin V K for 21 days and discharged home in stable condition. Immunocompromised patients with<br />

animal exposure should be considered for Streptococcus equi bacteremia as humans are rare<br />

hosts. Strangles infected horses are treated in isolation but it is unclear if infected humans require<br />

isolation precautions. Further studies into understanding the transmission <strong>of</strong> S. equi from equine-tohumans<br />

may give insight into cross species bacterial evolution.<br />

author: Dr. Lee Lu Bach, MD<br />

INTRODUCTION: Emesis can manifest as a presenting feature <strong>of</strong> various systemic diseases. Sometimes,<br />

this nonspecific symptom can be a diagnostic challenge. We present a curious case <strong>of</strong> persistent nausea<br />

and vomiting.<br />

CASE PRESENTATION: A 47-year-old African <strong>American</strong> male with a past medical history <strong>of</strong> poorly<br />

controlled hypertension and ventral hernia presented with intractable nausea and non-bilious, nonbloody<br />

vomiting. He reported early satiety with a 30 pound unintentional weight loss. He denied<br />

dysphagia, odynophagia, fevers, abdominal pain, diarrhea or constipation. He had no sick contacts or<br />

recent travel. The patient’s symptoms started 2 months prior at which time he was admitted with<br />

dehydration and acute kidney injury with a creatinine <strong>of</strong> 3.4 mg/dL from a normal baseline. Urinalysis<br />

showed granular casts and proteinuria. He was managed conservatively with bowel rest, anti-emetics<br />

and hydration, and his creatinine improved to 2.0 mg/dL but failed to normalize completely. He was<br />

presumed to have developed chronic kidney disease due to long-standing untreated hypertension as<br />

evidenced by medical renal disease on ultrasound. His nausea and vomiting persisted with intermittent<br />

flares requiring multiple emergency room visits. One month later, he was admitted again for the same<br />

complaints. An abdominal CT scan showed an incidental supraumbilical hernia along with a ventral<br />

hernia, but no evidence <strong>of</strong> incarceration. The ventral hernia was thought to be the source <strong>of</strong> his<br />

intractable nausea and vomiting; thus, a laparoscopic hernia repair was performed. Few weeks later, his<br />

symptoms recurred. Physical exam at that time was significant for exaggerated bowel sounds and a liver<br />

span <strong>of</strong> 14cm. Laboratory studies showed a creatinine <strong>of</strong> 2.9mg/dL and 3(+) proteinuria. Renal<br />

ultrasound reported left and right kidney size to be 13.7 and 12.8cm, respectively. Esophagogram was<br />

normal, and gastric emptying study showed accelerated gastric emptying. An<br />

esophagogastroduodenoscopy (EGD) revealed antral erythema, and the biopsy <strong>of</strong> duodenal mucosa was<br />

positive for Congo red staining. Serum protein electrophoresis identified IgG kappa and lambda M<br />

spikes. Bone marrow biopsy showed 5% plasma cells. A diagnosis <strong>of</strong> “AL” amyloidosis with<br />

gastrointestinal involvement was made. The patient received bortezomib and dexamethasone<br />

treatment and had resolution <strong>of</strong> his symptoms.<br />

DISCUSSION: Nausea and vomiting is one <strong>of</strong> the most common complaints but at times can implicate<br />

specific diagnostic clues. Gastric and duodenal involvement in “AL” amyloidosis occurs in 8% <strong>of</strong> patients<br />

by biopsy, with only 1% cases being symptomatic. Patients typically present with nausea, vomiting,<br />

epigastric pain, and bleeding. Weight loss is an independent poor predictor <strong>of</strong> survival. Treatment<br />

involves the same chemotherapy used in multiple myeloma. Hence, although rare, gastrointestinal<br />

symptoms in a patient with hepatomegaly, proteinuria, and renal dysfunction should raise suspicion for<br />

amyloidosis.<br />

Everything Old is New Again: Weakly positive AFB Cavitary Lesion in an HIV infected patient with<br />

Sepsis.<br />

Niru Cepeda-Iruegas, MD Other Authors: James F. Hanley, MD Laura Garcia, MD<br />

INTRODUCTION: Rhodococcus equi infections have been associated with pr<strong>of</strong>ound impairment <strong>of</strong><br />

cellular mediated immunity, predominantly AIDS with CD4 lymphocyte counts below 200/microL, but<br />

can also be seen in lymphoproliferative malignancies, solid organ transplants, chronic steroid and<br />

immunosuppressive therapy use. R. equi is a pleomorphic gram positive rod. It can be an acid fast<br />

producer and have a micolic acid cell wall. Route <strong>of</strong> inoculation is typically inhalational (cases <strong>of</strong><br />

inoculation by ingestion, post-trauma or wound superinfection have been reported as well) with these<br />

bacteria usually affecting the lung and GI tract <strong>of</strong> immunocompromised patients.<br />

Before the AIDS epidemic, human related disease was rarely published, however with the increasing<br />

prevalence <strong>of</strong> AIDS, Rhodococcus equi infections became more common. Nowadays it is well known that<br />

ART and prophylaxis for MAC has contributed to the decline in R. equi cases.<br />

CASE PRESENTATION: 43 year old man with history <strong>of</strong> smoking presented with a 1 month history <strong>of</strong><br />

dry cough, pleuritic chest pain, weight loss, and generalized weakness. Physical exam revealed an<br />

afebrile cachectic male in mild respiratory distress with clubbing and seborrheic dermatitis.<br />

Further testing revealed bilateral infiltrates and blebs on CXR, HIV viral load <strong>of</strong> 400,000 copies, a CD4 <strong>of</strong><br />

26 c/uL, and a negative PCP PCR.<br />

During hospitalization, he was treated for community acquired pneumonia and was discharged with<br />

ART, fluconazole, azithromycin, sulfamethoxazole/trimethoprim and a pending bronchoaveolar lavage<br />

report.<br />

4 months later, the patient presented after not filling the discharge medications with low grade fever,<br />

hypotension, tachypnea, dry cough, and an episode <strong>of</strong> hemoptysis. During this admission workup<br />

revealed a cavitary lesion in right upper lobe seen on CXR, a CD4 count <strong>of</strong> 8 c/uL, AFB report positive for<br />

branching rods, and blood cultures positive for Rhodoccocus equi. He was treated with rifabutin and<br />

vancomycin IV for 2 weeks.<br />

DISCUSSION: Rhodoccocus equi infections are uncommon in the general population and have<br />

undergone fluctuating incidence before, during and after the AIDS epidemic. Needless to say AIDS and<br />

other immune-compromised patients have increased risk for this infection.<br />

Infection usually compromises the pulmonary and gastrointestinal system. 50% <strong>of</strong> the patients infected<br />

with Rhodoccocus equi who present with a cavitary lesion will have bacteremia even in the absence <strong>of</strong><br />

systemic inflammatory response syndrome criteria, and consequently blood cultures will be crucial in<br />

the diagnostic approach.<br />

Prognosis in R. equi infected AIDS patients depends on prompt diagnosis and treatment which is difficult<br />

because it may be thought <strong>of</strong> as a contaminant and a high index <strong>of</strong> suspicion is fundamental.<br />

Acute abdomen in systemic lupus erythematosus: is surgery warranted?<br />

Cindy Douglas, MD<br />

INTRODUCTION:Lupus peritonitis is a rare entity that may present with signs and symptoms identical<br />

to an acute abdomen. Early diagnosis is important not only for determining management strategies, but<br />

also to avoid unnecessary surgical intervention.<br />

CASE PRESENTATION: A 44 year-old African <strong>American</strong> female presented to the emergency department<br />

for a one week history <strong>of</strong> increasing abdominal pain and distension. The pain was described as severe,<br />

constant, and diffuse, and was associated with vomiting, fevers, and chills. Physical exam revealed a<br />

distended abdomen with exquisite tenderness to palpation and involuntary guarding. CT scan showed<br />

only trace free fluid in the abdomen with areas <strong>of</strong> nonspecific small bowel wall thickening. The patient’s<br />

past medical history was significant for SLE, managed with chronic Cellcept and low dose prednisone<br />

therapy, and her disease had been well-controlled, with her last flare occurring several years prior to her<br />

current admission. Because <strong>of</strong> her chronically immunosuppressed state and concern for spontaneous<br />

bacterial peritonitis, a paracentesis was performed; prelimary studies showed the fluid to be exudative<br />

but non-inflammatory, with RBC count 280, WBC 370 (total granulocyte count 52). She was started on<br />

broad-spectrum antibiotics pending further results <strong>of</strong> the fluid studies. General surgery was called in<br />

anticipation for emergent laparotomy, as the patient continued to have severe abdominal pain and<br />

increasing distension despite antibiotic therapy, intravenous fluids, and pain medication. Shortly before<br />

being taken for surgery for a suspected acute abdomen <strong>of</strong> unclear etiology, the patient was seen by<br />

Rheumatology, who recommended high-dose intravenous corticosteroids for possible lupus<br />

serositis. The patient showed an immediate response, with marked improvement in both her abdominal<br />

pain and distension. Surgery was avoided, and the patient’s symptoms resolved over the next several<br />

days on continued steroid therapy. Ascitic fluid gram stain and cultures were eventually found to be<br />

negative; at that time, serum complement levels were also noted to be markedly decreased. The final<br />

diagnosis was lupus peritonitis presenting as an acute abdomen.<br />

DISCUSSION: Peritonitis as a manifestation <strong>of</strong> active lupus is relatively rare and is usually associated<br />

with other symptoms <strong>of</strong> an acute lupus flare; rarely does it occur in the absence <strong>of</strong> other signs <strong>of</strong> disease<br />

activity. Symptoms <strong>of</strong> lupus peritionitis closely mimic those <strong>of</strong> an acute abdomen, which may lead to a<br />

mistaken diagnosis and, in some instances, unnecessary surgery. Patients with lupus peritonitis do not<br />

require surgery and respond dramatically to pulse steroids, <strong>of</strong>ten recovering from the episode without<br />

sequelae. In patients with systemic lupus erythematosus who present with acute abdominal pain, the<br />

diagnosis <strong>of</strong> lupus peritonitis must be considered in order to facilitate early diagnosis and prompt<br />

therapeutic management, as well as preventing unnecessary surgical procedures.<br />

Acute Liver Failure in Pregnancy - Not Always HELLP<br />

Jennifer Lynne Jarvie Second Author: Stephen Harder<br />

INTRODUCTION: CASE PRESENTATION: A 26 year-old G4P3 Caucasian female in her 27 th week <strong>of</strong><br />

pregnancy presented with right sided abdominal and flank pain for one week. She had taken ibupr<strong>of</strong>en<br />

and acetaminophen for the pain at recommended doses with some relief. On the initial physical exam<br />

she had a low-grade fever and right upper quadrant tenderness. The laboratory analysis was significant<br />

for a mild transaminitis with ALT 164 U/L and AST 179 U/L. Alkaline phosphatase (AP) and total bilirubin<br />

were within normal limits, as were the hematocrit and platelets.<br />

The patient was admitted and over the next five days she experienced a rapid clinical decline<br />

characterized by hypotension, tachycardia and somnolence with intermittent fevers. Physical<br />

examination was remarkable for an altered sensorium, asterixis, increased right upper quadrant<br />

tenderness and a palpable liver edge. Repeat laboratory testing was concerning for an AST >4000 U/L,<br />

ALT 2265 U/L, AP 280 IU/L, and total bilirubin 2.7 mg/dL. She became acutely anemic (hematocrit 22.0<br />

mg/dL), thrombocytopenic (platelets 22 x 10(3) uL) and coagulopathic (INR 1.85). No schistocytes were<br />

seen on smear. She was emergently delivered by cesarean section for concern <strong>of</strong> HELLP (Hemolysis,<br />

Elevated Liver Enzymes and Low Platelets) syndrome or acute fatty liver <strong>of</strong> pregnancy.<br />

Post-partum she was transferred to the intensive care unit. Despite delivery her liver injury<br />

progressed. A secondary liver workup revealed ceruloplasmin 16.5 mg/dL (reference range 16.0 – 45.0)<br />

and a ferritin over 41,000 ng/mL (reference range 13.0 – 150.0 ng/mL). The serum acetaminophen level<br />

Discerning the origin <strong>of</strong> bone marrow blast cells, a 59 year old Caucasian male with pancytopenia<br />

Myung Sun Kim, MD Co Author: Jose A. Perez MD<br />

INTRODUCTION: Multiple myeloma is a clonal B-cell neoplasm that affects plasma cells. The diagnosis<br />

is made by establishing the presence <strong>of</strong> M protein in serum or urine, and confirming the presence <strong>of</strong><br />

more than 10% clonal plasma cells in the bone marrow. The following case is a rare presentation <strong>of</strong><br />

multiple myeloma with myel<strong>of</strong>ibrosis, pancytopenia, anaplastic plasma cell morphology, and absence <strong>of</strong><br />

serum paraprotein.<br />

CASE PRESENTATION: A 59 year old Caucasian male was referred to hematology clinic for<br />

pancytopenia. He was morbidly obese and had a 1 month history <strong>of</strong> progressively worsening right sided<br />

back pain aggravated by movement which severely limited his activities. On examination, he appeared<br />

comfortable. Musculoskeletal exam showed point tenderness <strong>of</strong> the right posterior 5 th rib. Abdomen<br />

was s<strong>of</strong>t and globoid, with tenderness in both upper quadrants. Splenomegaly was not appreciated.<br />

Complete blood count was remarkable for white count <strong>of</strong> 3.27K/µL, hemoglobin <strong>of</strong> 8.3g/dL, hematocrit<br />

<strong>of</strong> 25.9% and platelet count <strong>of</strong> 78K/µL. Renal function was normal with BUN <strong>of</strong> 21mg/dL and creatinine<br />

<strong>of</strong> 1.1mg/dL. Calcium level was 9.5mg/dL with serum protein and albumin 6.0g/dL and 3.9g/dL<br />

respectively. Peripheral blood smear showed 7% immature neutrophils, 1 nucleated RBC and 1 tear drop<br />

cell per high powered field, suggesting myel<strong>of</strong>ibrosis. Bone marrow biopsy demonstrated tumor clumps<br />

with more than 50% blast-like cells exhibiting prominent cytoplasmic projections. These cells resembled<br />

budding platelets and were suggestive <strong>of</strong> acute leukemia. A diagnosis <strong>of</strong> acute megakaryoblastic<br />

leukemia (M7) commonly presenting with acute myel<strong>of</strong>ibrosis and pancytopenia was made. The patient<br />

was admitted for chemotherapy. Further studies surprisingly revealed that the tumor cells were positive<br />

for CD138, MUM-1 and kappa light chain on immunohistochemical staining, confirming a diagnosis <strong>of</strong><br />

multiple myeloma. Serum protein electrophoresis did not show a M spike, however Kappa/Lambda ratio<br />

was markedly elevated to 643. Beta-2 microglobulin was elevated to 5.4mg/L. The patient began<br />

treatment with bortezomib, dexamethasone and doxorubicin and is being worked up for stem cell<br />

transplant.<br />

DISCUSSION: This is a rare case <strong>of</strong> nonsecretory multiple myeloma with highly undifferentiated<br />

cytomorphology. The initial presentation with myel<strong>of</strong>ibrosis and pancytopenia in the absence <strong>of</strong><br />

monoclonal gammopathy led to a misdiagnosis <strong>of</strong> acute myeloid leukemia. Nonsecretory myeloma<br />

represents less than 5% <strong>of</strong> all cases <strong>of</strong> multiple myeloma and the absence <strong>of</strong> monoclonal gammopathy,<br />

may delay the diagnosis. This case illustrates that multiple myeloma still remains a possible cause <strong>of</strong><br />

bone marrow infiltration in the absence <strong>of</strong> serologic evidence <strong>of</strong> a paraprotein and that the use <strong>of</strong> tumor<br />

specific markers on immunohistochemical staining is important in avoiding the misdiagnosis and<br />

mistreatment <strong>of</strong> hematologic malignancies.<br />

LEVAMISOLE: COCAINE'S DEADLY SECRET<br />

Manuel Lopez Vazquez, MD (Associate) Natraj Shanmugam, MD (Associate) James Hanley, MD (FACP)<br />

Nabeel Sarhill, MD<br />

INTRODUCTION: Cocaine can be hazardous not only for its cardiovascular effects but also due to<br />

lesser-known toxicities from drug-diluting agents. We present a case <strong>of</strong> a patient who ingested cocaine<br />

and survived both a coronary event and agranulocytosis, most likely related to the cutting agent<br />

levamisole.<br />

CASE PRESENTATION: A 38-year-old Mexican man presented with one day <strong>of</strong> sudden onset left shin<br />

pain, with generalized weakness and dyspnea. His temperature was 99.0, blood pressure 108/72, pulse<br />

90, respiratory rate 24. On exam he had erythema <strong>of</strong> the left shin, calf tenderness and decreased range<br />

<strong>of</strong> motion. EKG showed right bundle branch block without ST elevation. Dopplers <strong>of</strong> the lower<br />

extremities were negative. He had a WBC count <strong>of</strong> 300 with an absolute neutrophil count <strong>of</strong> 0.<br />

Peripheral smear showed no blast forms. Bone marrow showed no evidence <strong>of</strong> leukemia. Flow<br />

cytometry did not reveal any immunophenotypic evidence <strong>of</strong> a myeloid stem cell disorder or non-<br />

Hodgkin’s lymphoma. CK rose above 8,000 and troponin I peaked at 2.3. Urine toxicology was positive<br />

for cocaine and cannabinoids. HIV screen was negative. He was medically managed, and placed on<br />

broad spectrum antibiotics and filgastrim. Although he initially denied cocaine usage, upon further<br />

questioning the patient admitted to having snorted cocaine powder on a daily basis and obtaining the<br />

drug from a dealer in Mexico who had been mixing the cocaine with an unknown substance. At this<br />

point, the etiology <strong>of</strong> his neutropenia was highly suspected to be levamisole-contaminated<br />

cocaine. Unfortunately, initial urine samples were unavailable for levamisole testing at the time the<br />

diagnosis was being contemplated. His WBC count eventually recovered within five days and the skin<br />

lesion resolved.<br />

DISCUSSION: Ultimately, the patient survived both common (myocardial infarction) and uncommon<br />

(agranulocytosis) complications <strong>of</strong> cocaine abuse. Levamisole is a veterinary antihelminthic drug once<br />

used in humans as adjuvant therapy for colon cancer. Eighty-two percent <strong>of</strong> seized cocaine in the U.S. is<br />

adulterated with levamisole. Dealers prefer levamisole over traditional cutting agents such as baking<br />

soda because it potentiates cocaine's euphoric effects. However, in select patients (2.3%) it causes<br />

agranulocytosis via immune-mediated destruction <strong>of</strong> cell membranes by antineutrophil antibodies,<br />

predisposing patients to serious infections. It may also produce an ANCA-related cutaneous vasculitis.<br />

Clinicians need to be cognizant <strong>of</strong> these rare but life-threatening complications when managing patients<br />

who use cocaine.<br />

Single Coronary artery with apical ischemia<br />

Kamil Muhyieddeen, MD<br />

INTRODUCTION: Single coronary artery is an extremely rare congenital anomaly. Most isolated single<br />

coronary artery anomalies are benign. However, 15% <strong>of</strong> isolated single coronary artery may have<br />

myocardial ischemia directly caused by the abnormal anatomy <strong>of</strong> the arteries and not by coronary artery<br />

disease. Herein, we report a case <strong>of</strong> single coronary artery causing apical ischemia, with the absence <strong>of</strong><br />

coronary artery disease.<br />

CASE PRESENTATION: A 56 year-old female presented with chest pain. She had no risk factors for<br />

coronary artery disease. Physical exam was normal. Her cardiac enzymes were negative. EKG showed<br />

normal sinus rhythm. Chest X- ray was normal.<br />

Stress exercise echocardiogram showed left ventricular apical ischemia. Coronary angiogram showed no<br />

significant lesions in a large dominant right coronary artery, but the left coronary artery could not be<br />

found. CT coronary angiography for further evaluation <strong>of</strong> the coronary artery anatomy was done. It<br />

showed a single coronary artery arising from the right coronary sinus. It coursed around the entire<br />

atrioventricular groove, giving <strong>of</strong>f all main coronary branches, and then directed anteriorly, ending in the<br />

mid anterior interventricular groove. Patient was managed medically.<br />

DISCUSSION: Coronary artery anomalies are found in about 1.3% <strong>of</strong> patients undergoing coronary<br />

angiography. However, Single coronary artery is an extremely rare congenital anomaly characterized by<br />

a single coronary artery ostium from an aortic sinus, which is seen in only 0.024% to 0.066% <strong>of</strong> patients<br />

who undergo coronary angiography. Most anomalies are encountered as incidental findings during<br />

coronary angiography or at autopsy. About 80% <strong>of</strong> coronary artery anomalies are benign while 20%<br />

produce life threatening symptoms including arrhythmias, syncope, myocardial infarction, or sudden<br />

death. 15% <strong>of</strong> isolated single coronary artery may have myocardial ischemia directly caused by the<br />

abnormal anatomy <strong>of</strong> the arteries and not by coronary artery disease. CT coronary angiography is a<br />

noninvasive method that provides detailed 3-dimensional (3D) visualization <strong>of</strong> complex coronary artery<br />

anatomy, and has currently become the method <strong>of</strong> choice for the detection and classification <strong>of</strong><br />

coronary artery anomalies.<br />

A Case Of Refractory Autoimmune Hepatitis Treated With Rituximab<br />

CPT Stephen J Park, MC USAF<br />

INTRODUCTION: Autoimmune hepatitis (AIH) is a chronic hepatitis <strong>of</strong> unknown etiology that is<br />

characterized by circulating autoantibodies, hypergammaglobulinemia, and necroinflammatory changes<br />

on liver histology. The disease is rare, with a mean incidence <strong>of</strong> 1-2 per 100,000, and is more frequent in<br />

females. Most cases respond to the standard therapy <strong>of</strong> corticosteroids and azathioprine.<br />

CASE PRESENTATION: A 23 year old previously healthy male presented with several months <strong>of</strong><br />

fatigue. He otherwise denied fever, jaundice, pruritis, ascites, or abdominal pain. He had no history <strong>of</strong><br />

alcohol or illicit drug use, and was not taking any medications. He was afebrile with stable vital<br />

signs. Physical exam showed splenomegaly but no other abnormalities. Lab values revealed a WBC<br />

count: 2,700; platelet count 96,000; AST: 338 U/L; ALT: 264 U/L; total bilirubin: 2.5 mg/dL (direct<br />

bilirubin: 1.5 mg/dL); alkaline phosphatase: 125 IU/L; albumin 3.3 g/dL; INR: 1.4. Further workup<br />

showed positive antinuclear, anti-smooth muscle, anti-actin, and perinuclear antineutrophil cytoplasmic<br />

antibodies, and an elevated immunoglobulin G level <strong>of</strong> 2606 mg/dL. MRI <strong>of</strong> the liver demonstrated<br />

cirrhosis, splenomegaly, and a 1.2 cm right hepatic lobe lesion, which upon further evaluation with a<br />

three phase liver CT, excluded hepatocellular carcinoma. A percutaneous liver biopsy revealed severe<br />

interface hepatitis with a lymphoplasmacytic infiltrate and cirrhosis. Autoimmune hepatitis was<br />

diagnosed, and treatment was started with prednisone 40 mg daily. After one month, the patient’s<br />

fatigue had not improved and his AST, ALT, and bilirubin had increased to 616 U/L, 522 U/L, and 3.8<br />

mg/dL, respectively. Mycophenolate m<strong>of</strong>etil was then added. However, after 7 months <strong>of</strong> this regimen,<br />

his AST, ALT, and bilirubin remained elevated at 438 U/L, 302 U/L, and 3.1 mg/dL, respectively. He was<br />

then treated with two infusions <strong>of</strong> rituximab, and two months later his AST, ALT, and bilirubin have<br />

decreased to 124 U/L, 87 U/L, and 2.2 mg/dL, respectively, with improvement in his fatigue.<br />

DISCUSSION: The standard treatment for AIH is prednisone or lower dose prednisone in combination<br />

with azathioprine; our patient failed prednisone and azathioprine was relatively contraindicated due to<br />

his leukopenia and thrombocytopenia. Mycophenolate m<strong>of</strong>etil, widely considered the most promising<br />

alternative agent, was also ineffective. Initial treatment with rituximab, a monoclonal antibody directed<br />

against B-lymphocytes, has been effective thus far. Rituximab, while approved for chronic lymphocytic<br />

leukemia, Non-Hodgkin’s lymphoma, and rheumatoid arthritis, has been shown to have some benefit in<br />

AIH, however this is limited to isolated case reports and a six patient phase 1 study. It may prove to be<br />

an option in the future for AIH treatment failures or for patients who are poor candidates for steroids<br />

and azathioprine, but further investigation is necessary.<br />

PULMONARY LANGERHANS CELL HISTIOCYTOSIS MIMICKING UNCONTROLLED ASTHMA<br />

Frederic A Rawlins III Capt, USAF, MC (associate), James E Hull Capt, USAF, MC(associate), Julia A<br />

Morgan D.O. SAUSHEC Internal Medicine, San Antonio, TX<br />

INTRODUCTION: INTRODUCTION: Pulmonary langerhans cell histiocytosis (PLCH) is an upper lobe<br />

predominant cystic lung disease that is cause by abnormal proliferation and dissemination <strong>of</strong> histiocytes<br />

within the pulmonary parenchyma. PLCH is typically seen in young adults who abuse tobacco and is<br />

most prevalent in the third or fourth decade <strong>of</strong> life without gender predominance. There is a tendency<br />

for females to present at a later age than males. Typical symptoms on presentation include dyspnea,<br />

cough or chest pain. Occasional patients present with constitutional symptoms or hemoptysis. Rarely<br />

patients present with a pneumothorax or symptoms <strong>of</strong> pulmonary hypertension. There have been few<br />

case reports in English literature <strong>of</strong> PLCH developing in asthmatics, none <strong>of</strong> which mimic symptoms <strong>of</strong><br />

uncontrolled asthma. We report a patient who presented with uncontrolled asthma (dyspnea,<br />

wheezing, coughing and chest tightness) that was refractory to typical asthma therapy and was found to<br />

have PLCH upon further evaluation.<br />

CASE PRESENTATION: Case: A 26 year old female with active tobacco abuse, who was diagnosed with<br />

asthma based on symptoms and a positive methacholine challenge test (PC20 < 8) who presented with<br />

progressively worsening symptoms <strong>of</strong> dyspnea, wheezing, coughing and chest tightness. Her symptoms<br />

continued to progress despite appropriate inhaled therapy (inhaled corticosteroids/long acting betaagonists,<br />

anticholinergics), singulair, antihistamines and a proton pump inhibitor. Her pulmonary<br />

function testing, IgE level, ANCA levels and chest x-ray were unrevealing <strong>of</strong> the underlying etiology. High<br />

resolution CT (HRCT) scan <strong>of</strong> the chest revealed multiple upper lobe predominant thin walled cysts with<br />

scattered 3 mm nodules along the interlobular septa. Bronchoscopy with transbronchial biopsies<br />

revealed interstitial CD1a, S100 positive histiocytes confirming the diagnosis <strong>of</strong> PLCH.<br />

DISCUSSION: DISCUSSION: When typical therapy for asthma fails to control symptoms, further<br />

investigation into possible potentiating or alternative etiologies should be performed. There are few<br />

cases reported in English literature <strong>of</strong> PLCH associated with asthma. Our patient illustrates the<br />

diagnostic complexity <strong>of</strong> this rare disorder for which there is <strong>of</strong>ten a delay in diagnosis <strong>of</strong> up to several<br />

years due to the variability <strong>of</strong> symptoms and their severity on clinical presentation. HRCT scan <strong>of</strong> the<br />

chest typically reveals a combination <strong>of</strong> upper lobe predominant nodules and cysts. The diagnosis is<br />

confirmed with CD1a, S100 positive histiocytes on biopsy (bronchoscopy or surgical) with special stains.<br />

Birbeck granules on electron microscopy are pathognomonic, but not necessary for diagnosis. Cigarette<br />

smoking is either a cause or could potentiate PLCH, therefore tobacco cessation is the first line <strong>of</strong><br />

therapy. Rarely, patients do not respond to tobacco cessation alone and may require<br />

immunosuppressive therapy.<br />

DRUG INDUCED LUPUS ERYTHEMATOSUS IN A PATIENT WITH ULCERATIVE COLITIS TREATED WITH<br />

INFLIXIMAB PRESENTING AS RECURRENT PLEURAL EFFUSION<br />

CPT Charlene A Vestermark Gibb, DO, MAJ Michael Hjelkrem, MD (Member), LTC John Godino, MD,<br />

MAJ Karen Sky, MD (Member)<br />

INTRODUCTION: Throughout the years, multiple drugs have been reported to cause drug induced<br />

lupus erythematosus (DILE). With the increasing use <strong>of</strong> TNF-a inhibitors in inflammatory bowel disease<br />

(IBD) and rheumatologic diseases there are increasing reports <strong>of</strong> DILE in these medications.<br />

CASE PRESENTATION: Our case involves a 40 yo female with a long history <strong>of</strong> ulcerative colitis (UC)<br />

and IBD related arthritis treated with high dose infliximab every 6 weeks for 5 years. After 5 years <strong>of</strong><br />

treatment she began having increasing shortness <strong>of</strong> breath with multiple hospitalizations for recurrent<br />

left sided pleural effusions after a bout <strong>of</strong> pneumonia. The pleural fluid was exudative without evidence<br />

<strong>of</strong> infection and transbronchial biopsy showed no evidence <strong>of</strong> inflammation, infection, intraalveolar<br />

exudates, or malignancy. While initially unilateral, the pleural effusions eventually occurred on the right<br />

side as well, thus suggesting a cause other than pneumonia.<br />

Serum anti-nuclear antibody (ANA) was positive 1:5120 and ANA in the pleural fluid was positive to<br />

1:5120, as well. Additional labs revealed positive double stranded DNA (dsDNA) antibiody, negative<br />

Smith antibody, negative SSA and SSB antibodies and negative anti-histone antibodies. The pleural<br />

effusions completely resolved after stopping the infliximab and switching therapy to adalimumab.<br />

DISCUSSION: This is a case <strong>of</strong> bilateral, episodic pleural effusions most likely attibutible to infliximab<br />

based on resolution <strong>of</strong> symptoms after stopping the medication, a high titer positive ANA and positive<br />

dsDNA. With increasing use <strong>of</strong> anti-TNFa medications for autoimmune disorders more atypical cases <strong>of</strong><br />

DILE are appearing. Anti-TNF related DILE typically presents with rash, arthralgia and fever and while<br />

reported, most <strong>of</strong> the cases <strong>of</strong> pleural effusions due to TNF inhibitors have occurred on rheumatic<br />

diseases and are discussed in rheumatology literature. Infliximab has been used in Crohn’s disease since<br />

1998 and has more recently (2005) been approved for use in UC. This is the first reported case <strong>of</strong> a UC<br />

patient with infliximab related DILE manifesting as recurrent pleural effusions. This is important for<br />

internal medicine physicians to understand as recognition <strong>of</strong> this potential side effect is vital as<br />

symptom resolution requires discontinuation <strong>of</strong> the <strong>of</strong>fending agent.<br />

Neurocysticercosis or Neuro-metastatic Merkel Cell Carcinoma?<br />

Sonja Raaum MD Srinivas Tantravahi MBBS MRCP Theresa L. Werner MD<br />

INTRODUCTION: Merkel cell carcinoma is a rare non-melanoma skin cancer, with incidence rate in the<br />

general population <strong>of</strong> less than 0.5 per 100,000 person years. It is associated with increased age and<br />

history <strong>of</strong> extensive sun exposure, as well as a Polyomavirus identified in 2008. Recent literature<br />

suggests the incidence <strong>of</strong> Merkel cell carcinoma is increasing, and recognizing the manifestations <strong>of</strong> its<br />

disease will become more important in an aging population.<br />

CASE PRESENTATION: Patient was a 76 year old male with history <strong>of</strong> CAD, HTN, hyperlipidemia, BPH,<br />

rheumatoid arthritis, and stage IV Merkel Cell Carcinoma (MCC) <strong>of</strong> left parotid and left forehead, treated<br />

with chemotherapy with excellent response, who presented in August 2011 with abrupt onset <strong>of</strong><br />

confusion, aphasia, dysmetria, and inability to perform simple tasks. After presentation to outside ED,<br />

he had a generalized tonic-clonic seizure. Initial work-up with head CT revealed multiple hypodense<br />

lesions in right cortex. After stabilization, he was empirically started on Albendazole for presumed<br />

neurocystercisosis and transferred to University <strong>of</strong> Utah Neurology service.<br />

Prior to this presentation, patient had 2-3 week gradual onset <strong>of</strong> confusion after a syncopal episode.<br />

Regarding his oncology history, patient initially presented with a rapid growing lesion on left side <strong>of</strong><br />

forehead as well as an enlarged left parotid gland in February 2011. Biopsy revealed proliferative small<br />

to medium size cells that were negative for chromogranin, strongly positive for CK7 and CK20, and<br />

positive for synaptophysin; consistent with poorly differentiated neuroendocrine tumor or MCC. Staging<br />

PET CT demonstrated widespread osseous disease and a single metastatic lesion in the right hepatic<br />

lobe. He was treated with 4 cycles <strong>of</strong> Cisplatin and Etoposide and monthly Zoledronic Acid. He received<br />

G-CSF after each cycle to prevent neutropenia. Restaging PET CT on 06/30/11 showed no evidence <strong>of</strong><br />

disease other than diffuse uptake in bone, which was thought to be secondary to marrow stimulation<br />

from G-CSF.<br />

Initial differential diagnosis included neurocysticercosis, toxoplasmosis, and neuro-metastatic MCC.<br />

Work-up included lumbar puncture and CSF revealed mild elevation in protein and WBC count.<br />

Infectious work-up including VDRL, Toxoplasma IgG and IgM, as well as cystercercosis antibody IgG was<br />

negative. MRI <strong>of</strong> brain revealed multiple ring-enhancing lesions throughout the cerebellum and cortex.<br />

Patient was empirically treated with Albendazole during work-up, and did not exhibit any improvement<br />

in mental status. Oncology service was consulted given patient’s prior cancer history; given negative<br />

work-up as well as the findings on brain MRI the most likely diagnosis was neuro-metastatic MCC. Whole<br />

brain radiation was <strong>of</strong>fered, but given diagnosis the patient and his family elected to not pursue further<br />

treatment.<br />

DISCUSSION: While the patient had radiological findings suggestive <strong>of</strong> neurocystersicosis, this case<br />

does not meet criteria for diagnosis. Patient did not have detectable serum antibodies to Cysterceri and<br />

no resolution or improvement after Albendazole treatment. In addition, he had no risk factors for<br />

exposure. Other infectious work-up was negative, making the most likely diagnosis neuro-metastatic<br />

MCC.<br />

533


One month prior to diagnosis <strong>of</strong> neuro-metastatic disease, patient‘s scan showed no evidence <strong>of</strong> disease<br />

and he was asymptomatic. This was a very aggressive recurrence <strong>of</strong> disease as the median time to<br />

recurrence for MCC is 8 months. Neuro-metastatic disease is rare, and there are only 36 cases reported<br />

in literature.<br />

Chronic total occlusion <strong>of</strong> the proximal right coronary artery successfully treated via a retrograde<br />

percutaneous approach<br />

Capt Adam L. Ackerman, MD, USAF, MC LtCol Steve Kindsvater, MD, FSCAI, USAF, MC<br />

INTRODUCTION: Chronic total occlusion <strong>of</strong> the coronary artery (CTO) is defined as a >99% stenosis<br />

present for at least 3 months. One-third to one-half <strong>of</strong> patients with significant coronary artery disease<br />

have at least one CTO, but CTOs account for only 10-15% <strong>of</strong> percutaneous coronary interventions (PCI).<br />

Successful percutaneous revascularization <strong>of</strong> CTOs is shown to confer a significant survival benefit over<br />

failed revascularization, with higher rates <strong>of</strong> avoidance <strong>of</strong> CABG, and is associated with improvements in<br />

systolic function, angina burden, and exercise capacity. Procedural success (approximately 75%) is<br />

improving without a concomitant increase in complications. Antegrade approaches to proximal lesions<br />

can be complicated by a limited length <strong>of</strong> vessel to <strong>of</strong>fer support to the interventional wire. A retrograde<br />

approach via septal collateral channels has been shown to be effective and safe in limited studies.<br />

CASE PRESENTATION: Case #1: A 76-year-old male was referred for chronic dyspnea and lack <strong>of</strong><br />

exercise tolerance. Transthoracic echocardiogram showed a left ventricular ejection fraction (LVEF) <strong>of</strong><br />

25-30% with global hypokinesis. Coronary angiography revealed high-grade atherosclerosis including a<br />

chronic total occlusion (CTO) <strong>of</strong> the proximal right coronary artery (RCA); distal flow was dependent<br />

upon contralateral collaterals. An initial antegrade approach to the RCA lesion proved unsuccessful; the<br />

lesion was then treated using a retrograde approach. A wire was passed antegrade down the left<br />

anterior descending (LAD), through the septal arcade, and retrograde up the RCA, where the lesion was<br />

successfully crossed. PCI was then performed via an antegrade approach. Five months after the<br />

procedure, the patient’s symptoms remained markedly improved.<br />

Case #2: A 69-year-old male with a history <strong>of</strong> an enlarging renal mass was referred after a pre-operative<br />

myocardial perfusion study showed reversible inferior wall ischemia. Angiography revealed a CTO <strong>of</strong> the<br />

proximal RCA with septal collateralization. An initial antegrade approach to the RCA lesion proved<br />

unsuccessful. The lesion was then crossed in a retrograde fashion (see Case #1). At this point, the wire<br />

was further advanced through a guiding catheter in the ostium <strong>of</strong> the RCA, creating a loop through the<br />

heart with both ends exiting at either groin access site. Successful PCI was then performed in an<br />

antegrade fashion. The patient received bare metal stents to facilitate semi-urgent nephrectomy.<br />

DISCUSSION: Chronic total occlusion <strong>of</strong> the coronary artery (CTO) is a common finding in patients with<br />

significant coronary artery disease. Successful revascularization <strong>of</strong> CTOs may confer decreased mortality<br />

and symptomatic benefit to patients. Retrograde percutaneous techniques may be useful in proximal or<br />

ostial CTOs, but are dependent upon the presence <strong>of</strong> adequate collateral channels for procedural<br />

success.<br />

Dexmedetomidine In The Treatment Of Acute Alcohol Withdrawal Cpt Sabrina Sumner, DO<br />

(Associate), Ltcol Matthew Carroll, MD (Fellow) Keesler Medical Center, Biloxi, MS<br />

Sabrina M Sumner, DO<br />

INTRODUCTION: Complications <strong>of</strong> alcohol withdrawal are a common scenario every physician will<br />

encounter. First line efforts to manage withdrawal symptoms are with benzodiazepines, as these agents<br />

enhance GABA activity and prevent neuronal excitability and progression to delirium tremens. However,<br />

some cases require the addition <strong>of</strong> other agents to achieve appropriate levels <strong>of</strong> sedation, including<br />

antipsychotics, anticonvulsants, or beta-blockers. Here we present a case where the adjunctive use <strong>of</strong><br />

the sedative dexmedetomidine, a sympatholytic with alpha-2 (a2) receptor agonist activity, achieved<br />

sedation in a patient with acute alcohol withdrawal when other first-line agents failed.<br />

CASE PRESENTATION: The role for a2-agonists in the treatment <strong>of</strong> acute alcohol withdrawal has been<br />

studied in the past with clonidine. Several case reports exist using dexmedetomidine in this role, as it is<br />

ten times more selective for the a2-receptor. Whereas benzodiazepines target the GABA receptor, a2agonists<br />

target the noradrenergic system, providing a different pathway to achieve effect. The side<br />

effect pr<strong>of</strong>ile is comparable to alternative agents such as barbituates, benzodiazepines, and<br />

antipsychotics. Lastly, dexmedetomidine has been used successfully in combination with other agents<br />

without additive toxicity. This is a novel approach to a very common and serious medical condition that<br />

all physicians face. Currently, no prospective data exists for its use in the management <strong>of</strong> acute alcohol<br />

withdrawal.<br />

Taking A Bath: A Patient With Persistent Delirium<br />

Meredith A Hays, CPT, DO Second Author: David A. Dorsey, LTC, MD<br />

INTRODUCTION: The use <strong>of</strong> designer drugs that are not detectable in routine drug screens is becoming<br />

increasingly more common at Fort Bliss, TX. Soldiers are presenting with unexplained, atypical delirium<br />

that eventually clears over 24-72 hours. No etiology <strong>of</strong> can be found despite comprehensive medical<br />

evaluation including negative serum and urine drug screens. This report reviews one such case that was<br />

caused by intoxication with a legal designer drug methylenedioxypyrovalerone (MDPV), also known as<br />

“Bath Salts”.<br />

CASE PRESENTATION: A 26 year old male with a past medical history <strong>of</strong> PTSD and polysubstance abuse<br />

presented to WBAMC ER with delirium and hallucinations. The soldier had been reported missing by his<br />

unit and had been located by the military police earlier in the day. He was found in the corner <strong>of</strong> a<br />

shipping container in his underwear, mumbling to himself and curled up in the fetal position. Upon<br />

awakening, he became combative and attempted to flee. In the ER he was disheveled, volume depleted<br />

and tachycardic with fixed pinpoint pupils. He would answer questions appropriately as long as he was<br />

not touched. However, tactile stimulation caused markedly increased agitation. The soldier was<br />

admitted to the ICU for altered mental status. No etiology was identified despite comprehensive<br />

medical evaluation to include toxin screens, CT scan, lumbar puncture, and MRI. Over the course <strong>of</strong> five<br />

days in the ICU his mental status slowly improved. During one lucid interval he admitted to taking Rave-<br />

Ice, although he was unsure <strong>of</strong> what he actually ingested. On the sixth day <strong>of</strong> admission he had<br />

completely recovered and denied all use <strong>of</strong> drugs or alcohol. He was transferred to inpatient Psychology<br />

for evaluation and treatment. Some weeks later a specialty lab report returned positive for 3,4methylenedioxypyrovalerone<br />

(MDPV) or mephedrone in the urine.<br />

DISCUSSION: Designer drugs such as mephedrone are becoming an increasingly popular drug <strong>of</strong> abuse<br />

in the military. Under federal law these agents are sold legally in many states and are readily available<br />

on online and in some stores. Not only are these agents legal but they are undetectable in the standard<br />

drug assays. MDPV is <strong>of</strong>ten sold as “Bath Salts”, “Rave Ice”, or “Plant Food.” Like many <strong>of</strong> these newer<br />

agents MDPV intoxication does not present with a classic toxidrome that clinicians can readily<br />

identify. MDPV presents with multiple clinical features to include sympathomimetic effects,<br />

hallucinations, epistaxis and even death. The effects <strong>of</strong> these drugs <strong>of</strong>ten persist for greater than 48<br />

hours after ingestion as was the case with our patient. Army Medical Officers should have a high index<br />

<strong>of</strong> suspicion for designer drug intoxication when treating soldiers with unexplained delirium.<br />

mitral-aortic intervalvular fibrosa pseudoaneurysm<br />

CPT Amy N Stratton, DO (associate) Tomas Ferguson, MD (FACP, FIDSA) Jone Flanders, DO (FACP, FACC)<br />

INTRODUCTION: The mitral-aortic intervalvular fibrosa (MAIF) connects the anterior mitral leaflet to<br />

the posterior aortic root. The intervalvular fibrosa is an avascular fibrous body which is susceptible to<br />

injury/damage secondary to aortic valve replacement or bacterial endocarditis. Injury can result in<br />

intervalvular fibrosa pseudoaneurysm.<br />

CASE PRESENTATION: The patient is a 75 year old man who underwent aortic valve replacement<br />

(AVR) with a bioprosthetic valve secondary to aortic insufficiency. On histologic examination <strong>of</strong> the<br />

aortic valve he was found to have endocarditis. Culture <strong>of</strong> the Aortic as well as Mitral valves were<br />

matching strains <strong>of</strong> Staphlococcus epidermidis. He was subsequently treated with cefazolin (renally<br />

EOSINOPHILIC FASCIITIS: THE GROOVE SIGN IN A YOUNG MILITARY SOLDIER<br />

Aaron Pumerantz, DO (Associate) Nicholas Kortan, DO (Associate) Jess Edison, MD (Member)<br />

INTRODUCTION:Eosinophlic fasciitis (EF) is an extremely rare connective tissue disease with<br />

approximately 250 new cases per year, characterized by scleroderma-like cutaneous skin changes,<br />

hypergammaglobulinemia, and peripheral eosinophilia. It is crucial to distinguish the differences<br />

between systemic sclerosis (SSc) and EF. Although etiology remains unknown, prognosis is good as<br />

most patients are steroid responsive. We present a case <strong>of</strong> a young active duty male with EF.<br />

CASE PRESENTATION: A 27 year-old active duty white male presented with progressively worsening 5<br />

month history <strong>of</strong> bilateral legs then arms swelling, pain, and eventually skin hardening. He additionally<br />

noted myalgias, fevers, fatigue, and night sweats. No clear toxin exposure or new medications. Physical<br />

exam was notable for skin induration in bilateral forearms, and bilateral lower extremities from ankles<br />

to knees, with positive groove sign. The complete blood count was normal except for eosinophlia up to<br />

28%, and his inflammatory markers were elevated. The rest <strong>of</strong> his laboratory studies were<br />

unremarkable except for elevated immunoglobulin IgG. Left forearm skin and deep tissue biopsy<br />

revealed panniculitis, underlying fasciitis with lymphocytes, plasma cells, and eosinophils, most<br />

consistent with EF. There was no evidence <strong>of</strong> end organ damage. The diagnosis <strong>of</strong> EF was made based<br />

upon clinical presentation and biopsy. He was treated with oral corticosteroids 1mg/kg daily, with a<br />

slow taper, and experienced significant improvement.<br />

DISCUSSION: Our case is a common presentation <strong>of</strong> a rare connective tissue disease, with a classic<br />

physical exam finding. Physically active individuals and those enduring strenuous activities, especially<br />

athletes or active duty military soldiers are at increased risk <strong>of</strong> EF, a well documented precursor to the<br />

onset <strong>of</strong> this disease. It is important to understand the differential diagnosis as well as complications <strong>of</strong><br />

skin induration and hardening, as the management and prognosis differs significantly. Prognosis for EF<br />

is very good, primarily treated with high dose corticosteroids. With the presence <strong>of</strong> appropriate risk<br />

factors, clinicians should consider EF in the setting <strong>of</strong> scleroderma-like cutaneous skin changes.<br />

Case Report: Visceral Leishmaniasis (Kala-Azar) in a 34 year old Active Duty Soldier<br />

Brian Joseph Stout, MD, Associate Second Author: Gunther Hsue, MD, FACP<br />

INTRODUCTION: Visceral Leishmaniasis (Kala-Azar; Black Fever) is a potentially lethal disseminated L.<br />

Donovani infection characterized by malaise, fever, weight loss, and splenomegaly. In advanced disease,<br />

patients may exhibit severe anemia, thrombocytopenia and hepatic dysfunction. This systemic disease,<br />

which is much rarer than its cutaneous counterpart, results from transmission <strong>of</strong> the protozoan parasite<br />

through the bite <strong>of</strong> the female sandfly. The authors present a case <strong>of</strong> an active duty soldier who<br />

presented in theater with symptoms <strong>of</strong> severe nausea and vomiting, extreme lethargy, and rapid weight<br />

loss. This service member was ultimately diagnosed with visceral leishmaniasis, underwent treatment<br />

with amphotericin B, and exhibited rapid clinical improvement.<br />

CASE PRESENTATION: While stationed in Iraq, a 34 year old male presented with symptoms <strong>of</strong> severe<br />

nausea, vomiting, extreme lethargy, and rapid weight loss <strong>of</strong> 30 pounds in 2 months. He reported<br />

multiple sandfly bites occuring prior to onset <strong>of</strong> symptoms. His review <strong>of</strong> systems and examination were<br />

negative, to include no skin findings. A rK39 assay was performed at the patient’s duty station and<br />

returned highly positive. CT scan <strong>of</strong> the abdomen at that time showed mild enlargement <strong>of</strong> the<br />

spleen. The patient was ultimately seen in Infectious Disease clinic at Tripler Army Medical Center and it<br />

was recommended that he undergo definitive treatment for visceral leishmaniasis. Curative therapy was<br />

pursued with Ambisome. The patient received the standard seven infusions <strong>of</strong> liposomal amphotericin<br />

B, tolerating the therapy well, with only minimal and transient worsening <strong>of</strong> renal function. Patient<br />

exhibited rapid and complete resolution <strong>of</strong> symptoms.<br />

DISCUSSION: After infection with L. Donovani, there is a variable incubation period <strong>of</strong> 2-6 months,<br />

followed by parasitic replication within host macrophages in the reticuloendothelial system (spleen,<br />

liver, and bone marrow. Definitive diagnosis <strong>of</strong> visceral leishmaniasis requires demonstration <strong>of</strong> the<br />

parasite by histopathology or culture following needle aspiration or biopsy from the bone marrow or<br />

spleen. Histopathologic diagnosis requires visualization <strong>of</strong> amastigotes. Diagnosis by culture requires<br />

successful growth <strong>of</strong> the organism in Novy-McNeal-Nicolle or other parasitic growth media. A more<br />

recent development in the diagnosis <strong>of</strong> the disease is the rK39 assay test. rK39 is a 39-amino acid repeat<br />

<strong>of</strong> L. donovani kinesin, a recombinant product used as antigen in ELISA assays and also in rapid strip<br />

tests. Sensitivity for disseminated disease in clinically suspected cases is 81% and Specificity is 97%<br />

(PPV 98%; NPV 71%). In parasitologically confirmed cases, rK39 testing demonstrates 90% sensitivity<br />

and 99% specificity. Treatment regimens for Kala-Azar include Amphotericin B, Pentavalent antimonial<br />

drugs, Paromomycin (a parenteral aminoglycoside), and Miltefosine. Among these therapeutic<br />

modalities, liposomal amphotericin B (Ambisome) is the drug with the highest therapeutic efficacy and<br />

the most favorable safety pr<strong>of</strong>ile.<br />

CPT Pamela S Meyers, MC USA Second Author: COL Leslie W. Jackson, MC USA<br />

INTRODUCTION:We present the case <strong>of</strong> a 48-year-old female with known hypothyroidism who<br />

presented to rheumatology clinic for evaluation <strong>of</strong> multiple complaints including arthralgias and fatigue<br />

and later diagnosed with Celiac sprue.<br />

CASE PRESENTATION: A 48-year-old female with a history <strong>of</strong> hypothyroidism presented to the<br />

rheumatology clinic for evaluation <strong>of</strong> diffuse arthralgias and weakness in addition to paresthesias for 2<br />

months. Other associated symptoms included an upper extremity tremor, lower extremity muscle<br />

cramps and myoclonic jerking. Her medical history included a diagnosis <strong>of</strong> hypothyroidism and a<br />

questionable demyelinating cranial lesion diagnosed in 2005 with subsequent normal lumbar puncture<br />

and MRA in 2006. On exam the patient was noted to have a slight tremor <strong>of</strong> both hands and tenderness<br />

to palpation <strong>of</strong> bilateral MCPs without swelling. Initial lab workup was significant for an iron deficiency<br />

anemia, low vitamin D level, elevated ESR, 1:80 ANA, and elevated TSH. Hand radiographs showed<br />

moderate generalized osteopenia, narrowing <strong>of</strong> the interphalangeal joints distally, and narrowing <strong>of</strong> the<br />

first carpometacarpal joint. Iron deficiency anemia and transaminitis prompted a referral to GI for EGD<br />

and colonoscopy. The EGD revealed villous flattening <strong>of</strong> the duodenum. Biopsies and celiac panel<br />

confirmed the diagnosis <strong>of</strong> celiac disease. After 1 month on a gluten free diet, the paresthesias,<br />

weakness, and arthralgias improved.<br />

DISCUSSION: Celiac disease is a common disease that affects 1 in 300-500 people, generally <strong>of</strong><br />

Northern European descent. It is an autoimmune disorder characterized by villous atrophy <strong>of</strong> the small<br />

intestine. Patients typically present with symptoms <strong>of</strong> malabsorption, such as steatorrhea or weight<br />

loss. Some patients get the characteristic rash <strong>of</strong> dermatitis herpetiformis. As our case demonstrates,<br />

they can also present with a variety <strong>of</strong> other symptoms, such as paresthesias, ataxia, depression,<br />

arthralgias, and osteopenia from vitamin D deficiency. Initial workup <strong>of</strong> patient complaints <strong>of</strong>ten reveal<br />

an iron deficiency anemia and transaminitis, as was the case with this patient. Additionally, the finding<br />

<strong>of</strong> an elevated TSH as was seen in this patient with hypothyroidism is likely due to malabsorption <strong>of</strong><br />

levothyroxine. Diagnosis is suggested by EGD demonstrating villous flattening <strong>of</strong> the duodenum. Celiac<br />

panel, including gliadin IgA and anti-TTG Ab, are also suggestive <strong>of</strong> this diagnosis. Celiac sprue generally<br />

has a good response to a gluten free diet. However, there are refractory cases <strong>of</strong> sprue that require<br />

glucocorticoids, azathioprine, or 6-mercaptopurine. Close followup is needed, as patients with Celiac<br />

are at increased risk <strong>of</strong> malignancy, particularly non-Hodgkin’s lymphoma.<br />

Gynecomastia from Graves’: An Uncommon Cause <strong>of</strong> a Common Complaint<br />

CPT Vanya Wagler, DO, MAJ Kimberly Rieniets, DO<br />

INTRODUCTION:Graves’ disease is the most common cause <strong>of</strong> acquired hyperthyroidism and is due to<br />

autoantibodies to the thyroid stimulating hormone (TSH) receptor. Multiple clinical presentations <strong>of</strong><br />

Graves’ disease are possible including typical manifestations <strong>of</strong> hyperthyroidism, along with frequent<br />

opthalmopathy due to activation <strong>of</strong> T cells by TSH receptor antigen. We present a case <strong>of</strong> a 26-year-old<br />

male who presented with gynecomastia and galactorrhea and was found have TSH autoantibodies<br />

consistent with Graves’ disease. Gynecomastia and galactorrhea is a recognized but unusual initial<br />

presentation <strong>of</strong> Graves’ disease.<br />

CASE PRESENTATION: A previously healthy 26-year-old male active duty airmen presented to an<br />

ambulatory primary care clinic for evaluation <strong>of</strong> painful and enlarging breast tissue bilaterally along with<br />

clear nipple discharge. He also reported occasional palpitations and chest discomfort that interfered<br />

with sleep. His physical exam was remarkable for normal vital signs, diffusely enlarged, nontender<br />

thyroid gland, and bilateral gynecomastia. There was a slight resting tremor, and brisk but equal deep<br />

tendon reflexes bilaterally. There was no exophthalmos or visual field deficit. He was subsequently<br />

referred for cardiology evaluation and was found to have a normal EKG and echocardiogram. Thyroid<br />

studies were obtained and were notable for TSH <strong>of</strong> 0.02 mcIU/mL and free T4 <strong>of</strong> 5.25 ng/dL consistent<br />

with thyrotoxicosis. Beta-blocker was initiated and patient was referred for endocrine evaluation.<br />

Further lab studies were notable for TSH receptor antibody level <strong>of</strong> 99.16 IU/L, and thyroid stimulating<br />

immunoglobulin level 393% <strong>of</strong> control. Serum estradiol was elevated at 30 pg/L; estrogen was 180<br />

pg/mL and estrone was 53 pg/mL. Prolactin and follicle stimulating hormone were 6.48 ng/mL and<br />

7.07mIU/mL, respectively. Serum total testosterone was increased at 1669 ng/dL but bioavailable<br />

testosterone was decreased at 75.8 ng/dL. HCG was undetectable. Thyroid ultrasound showed diffuse<br />

enlargement with no focal lesions. Radioiodine uptake (RAIU) scan showed diffusely increased uptake <strong>of</strong><br />

79% at four hours consistent with Graves’ disease. After appropriate counseling, patient underwent I-<br />

131 ablation without complication. He was started on levothyroxine 100 mcg daily, and had gradual<br />

complete resolution <strong>of</strong> his presenting complaints including gynecomastia, galactorrhea, and<br />

palpitations; TSH and free T4 also returned to normal.<br />

DISCUSSION: Though gynecomastia is a relatively common finding in hyperthyroidism, there are few<br />

published case reports <strong>of</strong> gynecomastia as the presenting complaint in Graves’ disease. Etiology <strong>of</strong> this<br />

finding is thought to be due to an altered ratio <strong>of</strong> serum estradiol to testosterone, along with increased<br />

levels <strong>of</strong> sex hormone binding globulin (SHBG). As a result, total testosterone level may be normal or<br />

increased (as in our patient), but free testosterone is decreased.<br />

More Than Meets the Eye: When SLE Surprises Us All<br />

CPT Vanya Wagler, DO, MAJ Peter Henning, DO, LTC Michael Abel, MD<br />

INTRODUCTION:Systemic Lupus Erythematosus (SLE) is a chronic inflammatory disorder that can cause<br />

significant morbidity and premature death. Presenting features <strong>of</strong>ten include fatigue, arthritis or<br />

arthralgias, and typical skin findings, but the disease can affect essentially every organ system. We<br />

present a case <strong>of</strong> a young female with SLE whose early disease course was characterized by lifethreatening<br />

involvement <strong>of</strong> her lungs and GI tract. Definitive diagnosis was complicated by negative ANA<br />

testing by ELISA until an alternative assay was used.<br />

CASE PRESENTATION: An 18-year-old Hispanic female with a longstanding history <strong>of</strong> focal segmental<br />

glomerulosclerosis treated with oral cyclophosphamide presented to establish medical care. She had<br />

recently been hospitalized at an outside facility and given a presumptive diagnosis <strong>of</strong> Wegener’s<br />

granulomatosis manifested by diffuse alveolar hemorrhage (DAH) and positive MPO<br />

antibodies. Laboratory evaluation at our center was notable for MPO antibodies, lupus anticoagulant<br />

and a single positive ANA using bead ELISA technology. Multiple subsequent ANA results were negative.<br />

A paired blood sample was sent to Quest Diagnostics for fluorescent ANA testing which was positive at a<br />

titer <strong>of</strong> 1:1280, and she was diagnosed with SLE. Over the next 4 months she required multiple hospital<br />

admissions for recurrent DAH with a bland lung biopsy and superior mesenteric artery vasculitis causing<br />

life-threatening GI bleeding. She was cumulatively treated with multiple pulses <strong>of</strong> IV<br />

methylprednisolone, two courses <strong>of</strong> plasmapheresis, IV immune globulin, and combination rituximab<br />

with IV cyclophosphamide. These treatments induced clinical remission. Her chronic kidney disease<br />

progressed and she began hemodialysis (HD). Despite HD she had multiple episodes <strong>of</strong> volume overload<br />

and hypertensive crisis with seizures. During an episode <strong>of</strong> hypertensive crisis she developed mental<br />

status changes with bilateral cortical blindness. Brain MRI revealed diffuse white matter changes<br />

involving the cerebellum and posterior cerebrum consistent with reversible posterior<br />

leukoencephalopathy syndrome (RPLS). With aggressive medical management and kidney ablation with<br />

selective renal artery embolization, she regained blood pressure control with a resolution <strong>of</strong> cortical<br />

blindness. Subsequent MRI imaging showed dramatic resolution <strong>of</strong> the previous findings.<br />

DISCUSSION: Our patient illustrates that a broad range <strong>of</strong> initial presentations is possible in SLE.<br />

Although she did not have the more common complaints <strong>of</strong> arthralgias or rash initially, she had severe<br />

involvement <strong>of</strong> her lungs and GI tract requiring aggressive, multi-modal treatment. Previously published<br />

case reports have documented episodes <strong>of</strong> RPLS in association with SLE. Fluorescent ANA testing<br />

remains the gold standard. In patients with a high clinical suspicion for SLE, but negative ANA using<br />

ELISA technology, immun<strong>of</strong>luorescent ANA testing should be considered.<br />

Salmonella Strikes Again: Case <strong>of</strong> Salmonella heidelburg Wound Infection<br />

LT Caitlin O’Connor, MC, USN (Associate) and LCDR Jennifer Curry, MC, USN (Member) Naval Medical<br />

Center, Portsmouth, VA.<br />

INTRODUCTION: A major risk <strong>of</strong> prosthetic implant surgeries is the potential for development <strong>of</strong> a<br />

hardware infection. Bacteria that commonly infect the bones and s<strong>of</strong>t tissue can form a bi<strong>of</strong>ilm on<br />

hardware making their identification difficult and their eradication even more complicated. One <strong>of</strong><br />

these bi<strong>of</strong>ilm producing bacterial species is Salmonella. Non-typhoidal Salmonella (NTS) species are<br />

important food borne pathogens usually resulting in gastroenteritis. However 7-12% <strong>of</strong> NTS infections<br />

extend beyond the gastrointestinal tract causing bacteremia or focal suppurative<br />

infection. Immuncompromised patients are more susceptible to developing bacteremia or focal<br />

infection. We present a case <strong>of</strong> Salmonella heidelburg infection in an adult male with spindle cell<br />

carcinoma following radical resection and hardware placement.<br />

CASE PRESENTATION: Our patient is a 39-year-old male diagnosed with spindle cell sarcoma in the<br />

proximal left tibia. The lesion was resected and a Stryker modular rotating hinged knee, an Omnifit<br />

distal cement spacer with rotating hinges, and tibial insert were placed. Two months later, several<br />

members <strong>of</strong> the patient’s family developed a self-limited gastroenteritis. The patient was not afflicted<br />

with vomiting or diarrhea, but he did note the new onset <strong>of</strong> heartburn. One week following resolution <strong>of</strong><br />

these symptoms, he had left knee pain, swelling, and erythema. He underwent an incision and drainage,<br />

with extensive purulence noted in the s<strong>of</strong>t tissue surrounding the left knee and involving the internal<br />

hardware. A partial hardware exchange was performed utilizing tobramycin impregnated cement, and<br />

he was empirically started on vancomycin and piperacillin/tazobactam. Wound cultures (5 <strong>of</strong> 5) were<br />

positive for Salmonella heidelburg. The patient’s antibiotic therapy was transitioned to cipr<strong>of</strong>loxacin and<br />

azithromycin. He subsequently developed a prolonged QT, and antibiotics were changed to<br />

cipr<strong>of</strong>loxacin and trimethoprim-sulfamethoxazole. The patient is in remission 9 months status-post<br />

resection. He remains on long term antibiotic therapy.<br />

DISCUSSION: Immunocompromised patients are at increased risk for developing suppurative<br />

complications <strong>of</strong> NTS infections. They <strong>of</strong>ten develop focal s<strong>of</strong>t tissue Salmonella infections in the<br />

absence <strong>of</strong> gastrointestinal symptoms, similar to this patient. His case was complicated by the inability<br />

to fully remove the infected hardware and associated bi<strong>of</strong>ilm, thus a prolonged course <strong>of</strong> suppressive<br />

antibiotics was required. Historically Salmonella infections were treated with chloramphenicol,<br />

ampicillin, or co-trimoxazole. However, due to a rise in antibiotic resistant Salmonella, fluoroquinolones<br />

and extended-spectrum cephalosporins are now used as empiric alternatives. Emergence <strong>of</strong> resistance<br />

has been seen with prolonged antibiotic therapy, prompting our use <strong>of</strong> a dual antibiotic regimen. It is<br />

imperative to recognize uncommon bacteria causing life-threatening infections in the<br />

immunocomprised and appreciate the difficulties in treating these infections with long-term antibiotics.<br />

That's a "Rap": A Novel Use <strong>of</strong> Sirolimus to Prevent In-stent Restenosis After PCI in a Patient with<br />

Pseudoxanthoma Elasticum<br />

LT Ge<strong>of</strong>frey J Cole, MD, Second Author: LT Rolf Graning, MD, Third Author: LTC Matthew Jezior, MD<br />

INTRODUCTION: Pseudoxanthoma elasticum (PXE) is a rare inherited disorder due to a loss <strong>of</strong> function<br />

in the ABCC6 gene resulting in degeneration and calcification <strong>of</strong> elastic fibers. PXE is clinically expressed<br />

with cutaneous, ophthalmologic, and cardiovascular sequelae to include premature<br />

atherosclerosis. This case involves a novel use <strong>of</strong> sirolimus to prevent early in-stent restenosis (ISR) after<br />

percutaneous coronary intervention (PCI) with drug eluting stents (DES).<br />

CASE PRESENTATION: A 55 year old male with a history PXE presented to cardiology with a complaint<br />

<strong>of</strong> angina. Exercise treadmill testing revealed ischemic electrocardiogram (ECG) changes to include a run<br />

<strong>of</strong> ventricular tachycardia as well as reproduction <strong>of</strong> chest pain. Subsequent left heart catheterization<br />

(LHC) showed severe, obstructive three vessel disease and the patient underwent four vessel surgical<br />

revascularization. The patient had an uncomplicated post operative course, but was found to have poor<br />

functional capacity, chest pain, and ischemic ECG changes on routine stress testing prior to cardiac<br />

rehab enrollment. Subsequent LHC showed complete occlusion <strong>of</strong> all four bypass grafts. He then<br />

underwent staged PCI with a total <strong>of</strong> seven DES deployed with relief <strong>of</strong> symptoms. Within 6 months the<br />

patient had recurrent index angina requiring repeat LHC which showed rapid ISR <strong>of</strong> the majority <strong>of</strong> the<br />

previously placed stents. The patient again underwent PCI with placement <strong>of</strong> multiple DES which again<br />

resulted in significant ISR within seven months. Due to recurrent rapid ISR the patient was given a load<br />

<strong>of</strong> oral sirolimus in addition to PCI with DES deployed in two vessels followed by maintenance dosing <strong>of</strong><br />

oral sirolimus for 30 days post intervention in addition to dual anti-platelet therapy. The patient<br />

underwent subsequent LHC approximately one year after systemic sirolimus due to atypical chest pain<br />

which showed widely patent stents.<br />

DISCUSSION: PXE is a rare, inherited disorder characterized pathologically by progressive degeneration<br />

and calcification <strong>of</strong> the elastic fibers found primarily in the skin, eyes, and cardiovascular system with<br />

a highly variable phenotypic expression. The internal elastic lamina <strong>of</strong> medium sized arteries is <strong>of</strong>ten<br />

involved in PXE which leads to premature atherosclerosis due to calcification. The atheroma that is<br />

formed is histologically indistinguishable from other causes such as smoking, hypertension and<br />

hyperlipidemia. This case is unique due to the rapid failure <strong>of</strong> the bypass grafts and rapid recurrent ISR<br />

which we hypothesize is secondary to the underlying pathophysiology <strong>of</strong> PXE. This case is also unique as<br />

systemic sirolimus has been shown to be effective for prevention <strong>of</strong> ISR when used with bare metal<br />

stents but its use has not been reported in the medical literature with DES.<br />

Bloom where you are planted: Treatment Toxicity <strong>of</strong> Bloom’s Syndrome in a 46 year old woman.<br />

LT Priti Nath, MD Second author: John Nelson MD Third Author: Karen Bullock Russell MD (Member)<br />

INTRODUCTION: Bloom’s Syndrome is a rare autosomal recessive genetic disorder <strong>of</strong> the BLM gene<br />

yielding genomic instability due to mutation in DNA helicases and resultant chromosomal<br />

breaks. Manifestations include growth retardation, cranio-facial dysmorphic features,<br />

immunodeficiency and increased risk <strong>of</strong> fatal cancers. The mean age <strong>of</strong> incident malignancy and<br />

mortality is 25. There are only 265 registered patients worldwide. We report a case <strong>of</strong> a 46 year old<br />

woman with Bloom’s Syndrome presenting with a base <strong>of</strong> tongue (BOT) squamous cell carcinoma. Her<br />

treatment plan, management, and toxicity will be discussed.<br />

CASE PRESENTATION: LD is a 46 year old female with type II diabetes and no history <strong>of</strong> prior cancer.<br />

She initially presented with right otalgia and recurrent otitis followed by progressive pain and dysphagia.<br />

During fiber optic laryngoscopy, a right BOT biopsy revealed a primary squamous cell carcinoma, and<br />

PET-CT confirmed stage IVa: clinical T4N2cM0. Concurrent chemoradiotherapy was planned, with<br />

cisplatin at 30 mg/m 2 /week for curative intent due to her young age and questionable activity <strong>of</strong><br />

cetuximab given her underlying Bloom’s. On Day 7 <strong>of</strong> radiation and one dose <strong>of</strong> cisplatin, the patient<br />

was hospitalized with emesis, fever, and severe confluent oropharyngeal mucositis. Her absolute<br />

neutrophil count on admission was 1170 c/dl, with hemoglobin 8 g/dl and platelet count 195<br />

1000x/ul. Multiple transfusions and addition <strong>of</strong> G-CSF were required due to progressive pancytopenia,<br />

with count nadir on Day 17. Cisplatin was withheld, though RT was continued to a total goal dose <strong>of</strong><br />

7020 cGy. With count recovery, she received her second and final dose <strong>of</strong> cisplatin on Day 30 at only<br />

5mg/m 2 , and again developed severe neutropenia with fever. She required tracheotomy and recurrent<br />

critical care for management <strong>of</strong> subsequent epiglottitis with persistent secretions and MRSA<br />

pneumonia. Restaging PET-CT is pending.<br />

DISCUSSION: It is remarkable that LD developed her first malignancy in the 4 th decade <strong>of</strong> life. Based on<br />

one case report with Bloom’s and subsequent head and neck carcinoma in the literature, curative<br />

chemoradiotherapy was designed with concern for increased likelihood <strong>of</strong> toxicity, with lower doses <strong>of</strong><br />

cisplatin (30 mg/m2, 5 mg/m2) given weekly instead <strong>of</strong> every four weeks (100 mg/m2). LD<br />

demonstrated evidence <strong>of</strong> mucositis and severe pancytopenia, despite normal renal function, at week 2<br />

<strong>of</strong> treatment. While most patients develop mucositis with RT, this is usually after week 4; mild<br />

cytopenias are rarely seen with cisplatin. It is likely that her underlying Bloom’s DNA repair defect<br />

yielded prolonged cell turnover and bone marrow suppression, even with minimal cytotoxic<br />

chemotherapy. Patients with Bloom’s Syndrome should have age appropriate cancer screening to<br />

diagnose malignancy at an earlier stage for optimal outcome and decreased need for chemotherapy and<br />

radiation. Curative oncology treatment can be given as indicated, with expectation <strong>of</strong> exquisite and early<br />

toxicity.<br />

Fulminant reactivation hepatitis b with unsupervised sirolimus immunosupression for autologous<br />

kidney transplant<br />

Edward Thomas Stickle, Jr MD Second Author: Darren B Keller, MD<br />

INTRODUCTION: Immune suppression after organ transplant must balance rejection prophylaxis with<br />

adequate host immunologic defense. Each agent in use today also has a unique side effect<br />

pr<strong>of</strong>ile. Sirolimus has gained popularity in allographic kidney transplant due to reduced nephrotoxic<br />

effects compared to other agents. However, reactivation <strong>of</strong> prior infection, including hepatitis B, results<br />

in significant morbidity and mortality. To our knowledge, this is the first reported case <strong>of</strong> reactivation<br />

hepatitis B in conjunction with sirolimus therapy.<br />

CASE PRESENTATION: A 48 year old man who underwent autologous kidney transplant four years<br />

prior was referred to gastroenterology for jaundice, fatigue, and elevated liver enzymes. Pre-transplant<br />

screening was notable for non-reactive hepatitis B surface antigen and reactive hepatitis B core<br />

antibody. Immune suppression regimen was sirolimus 3mg and prednisone 7.5mg daily. One week<br />

prior to presentation, he developed anuria. Evaluation was notable for jaundice, hyperbilirubinemia<br />

(12.2 mg/dL), and elevated transaminases (AST 368 IU/L, ALT 254 IU/L), and INR <strong>of</strong> 2.8. Abdominal<br />

ultrasound demonstrated moderate ascites, hepatomegaly, without common bile duct<br />

dilatation. Repeat serology demonstrated reactive hepatitis B surface antigen, and viral load greater<br />

than 200,000,000 IU/ml. The patient was admitted to a nearby transplant center for reactivation<br />

hepatitis B, had a six-week intensive care stay, and died two days post liver transplant.<br />

DISCUSSION: Hepatitis B globally affects one-third <strong>of</strong> the population; exposure alone confers risk <strong>of</strong><br />

reactivation in an immune compromised host. Positive hepatitis B core antibody status implies<br />

exposure to hepatitis B, but not active infection. Hepatitis B may persist in the reticuloendothelial<br />

system as covalently closed circular DNA. Sirolimus binds the rapamycin mTOR receptor, inhibiting cell<br />

cycle progression <strong>of</strong> developing T-cells, suppressing the adaptive immune response and inhibiting<br />

clearance <strong>of</strong> hepatitis B virus. Recommended sirolimus serum values during therapy are less than 10<br />

ng/ml. This patient was noted to be supratherapeutic during his treatment, with values <strong>of</strong> 78.2 and 43.4<br />

prior to presentation. This is thought to be significant, although to what degree is unknown, as viral<br />

load was not monitored during treatment. Our hypothesis is over suppression allowed reactivation <strong>of</strong><br />

latent hepatitis B, while reconstitution <strong>of</strong> the immune system and recognition <strong>of</strong> disease ultimately led<br />

to fulminant liver failure. Acute viral hepatitis, whether de novo infection or reactivation, can rapidly<br />

escalate to an emergency. One must minimize these risks both pre and post-transplant, with screening<br />

including both hepatitis B surface and core antibody as well as surface antigen. Unexposed hosts should<br />

be vaccinated for primary prevention pre-transplant. Positive hepatitis B core antibody should incite<br />

close monitoring for reactivation. Post-transplant; sirolimus levels must be closely monitored, as<br />

elevated levels may be associated with reactivation <strong>of</strong> latent hepatitis B. Liver function tests should be<br />

monitored as they may herald reactivation <strong>of</strong> latent infection and prompt immediate evaluation <strong>of</strong><br />

hepatitis B status and viral loads. Reactivation hepatitis B may rapidly lead to fulminant hepatic failure,<br />

and must quickly be recognized.<br />

THE TRAPS OF MISSING THE BIG PICTURE<br />

LT Eric T. Meek, MC, USN and CDR Rachel U. Lee, MC, USN. Naval Medical Center, Portsmouth, VA<br />

INTRODUCTION:Recurrent fevers can be caused by infectious, neoplastic and rheumatologic<br />

conditions. Auto-inflammatory diseases, also known as periodic fever syndromes, are inherited diseases<br />

that can present with recurrent fevers and are <strong>of</strong>ten misdiagnosed for years because they present with a<br />

vague constellation <strong>of</strong> symptoms masquerading as other diseases.<br />

CASE PRESENTATION: The patient is a 42 year old male presenting with a history <strong>of</strong> recurring episodes<br />

<strong>of</strong> fevers and severe abdominal pain. The onset <strong>of</strong> symptoms acutely started with abdominal pain<br />

progressing to include pleurisy, night sweats, malaise, and anorexia with about a 15 pound weight<br />

loss. He denied any focal myalgia, conjunctivitis/periorbital edema, or rash. His symptoms occur 1 -2<br />

times per year lasting 1 - 3 weeks. Over the years, the patient has presented to sick call, many<br />

emergency rooms, and multiple specialists. The typical work-ups he received <strong>of</strong> colonoscopies and CT<br />

scans <strong>of</strong> his abdomen were normal, and CT scans <strong>of</strong> his chest were without any pulmonary<br />

emboli. Laboratory evaluations <strong>of</strong>ten showed elevated inflammatory markers with his CRP 63.5 and ESR<br />

58 and a mild normocytic anemia with no leukocytosis. However, extensive tests for pancreatitis,<br />

cholecystitis, appendicitis, and other inflammatory conditions were normal. A further history <strong>of</strong> the<br />

patient, coincidentally, revealed that his father, uncle, and identical twin 9 year old sons had similar<br />

symptoms. Due to the constellation <strong>of</strong> symptoms, family history, and their Irish background, genetic<br />

testing was performed on the father and his sons for the TNFRSF1A gene. Both the father and his twin<br />

sons had a heterozygous mutation at 102Y consistent with TNF-Receptor Associated Periodic Fever<br />

Syndrome (TRAPS), previously known as Familial Hibernian Fever.<br />

DISCUSSION: Inherited periodic fever syndromes include Familial Mediterranean Fever, Hyper-IgD<br />

syndrome, Familial Cold Autoinflammatory Syndrome, Muckle Wells Syndrome and TRAPS. TRAPS is an<br />

autosomal dominant disease that was first described in an Irish family in 1982 due to a mutation in the<br />

TNFRSF1A Gene. Diagnosis is made by genetic testing and treatment is aimed at decreasing<br />

inflammation with corticosteroids, anti-TNF therapy (entanercept) or anti-IL-1 receptor (anakinra).<br />

Prognosis is good with treatment and less then 25% will develop amyloidosis. This case demonstrates a<br />

patient presenting with common symptoms <strong>of</strong> an unusual disease. A thorough family history may have<br />

accelerated his diagnosis and hastened proper treatment for this patient and his family members. His<br />

course since diagnosis has been unremarkable with the administration <strong>of</strong> prednisone. He required this<br />

treatment 2-3 times (2-3 days <strong>of</strong> therapy) in the past year each with excellent results. As is the case<br />

with incomplete penetrance, one <strong>of</strong> his sons had more severe and frequent symptoms and required<br />

entanercept 50mg weekly but has had no reocurrence over the past year. The views expressed in this<br />

Drinking In The Groove! one Rare Form Of Pancreatitis: A Case Report And Review Of Literature.<br />

LT Haydar M Al-Eid, MD<br />

INTRODUCTION:Groove pancreatitis is a rare form <strong>of</strong> segmental chronic pancreatitis characterized by<br />

fibrous scars <strong>of</strong> the anatomic space between the dorso-cranial part <strong>of</strong> the head <strong>of</strong> the pancreas, the<br />

duodenum, and the common bile duct. We report a case <strong>of</strong> a male patient with a pancreatic mass who<br />

underwent pancreaticodoudenectomy with transverse colon resection and colo-colonic anastamosis.<br />

The mass was subsequently diagnosed as groove pancreatitis.<br />

CASE PRESENTATION: A 46 year-old alcoholic male presented with postprandial epigastric pain,<br />

nausea, vomiting, and a few episodes <strong>of</strong> c<strong>of</strong>fee ground emesis for 12 hours duration. He also had prior<br />

history <strong>of</strong> lightheadedness and weight loss over the past few months. He was initially evaluated for<br />

acute pancreatitis. Serum Lipase was 1352U/L (normal 23-300 U/L). CT scan followed by<br />

esophagogastroduodenoscopy (EGD) showed a pancreatic mass at the head <strong>of</strong> the pancreas which was<br />

bulging into and obstructing the pyloric outlet. Patient underwent a pancreaticodoudenectomy<br />

(Whipple’s) surgery during which the pancreatic mass was found to have invaded the mesentery which<br />

led to partial transverse colon resection and colo-colonic anastamosis. It was at this time that the frozen<br />

section pathology was read as consistent with groove pancreatitis. Post-operative course was<br />

complicated by bleeding which was treated conservatively. He subsequently had large NG tube output<br />

which led to a CT scan revealing a jeujenal obstruction. The patient underwent an exploratory<br />

laparotomy, internal hernia reduction, and J-tube placement. The second postoperative course was<br />

unremarkable. At discharge, patient was asymptomatic, afebrile, ambulating, and his post-operative<br />

pain was adequately controlled. The patient was seen one week after discharge and was doing well.<br />

DISCUSSION: Groove pancreatitis, although rare, is <strong>of</strong>ten diagnosed in 40 to 50 year-old alcoholic<br />

men. Clinical presentation is usually postprandial abdominal pain and impaired motility. These patients<br />

<strong>of</strong>ten have duodenal stenosis and postprandial vomiting which leads to significant weight loss. Jaundice,<br />

however, is unusual. The duration <strong>of</strong> the clinical symptoms may range from a few weeks to more than<br />

one year.<br />

Conclusion<br />

Groove pancreatitis <strong>of</strong>ten masquerades as pancreatic head carcinoma. This condition -although it is<br />

rare- should be kept in mind when making the differential diagnosis between pancreatic masses and<br />

duodenal stenosis. In all cases <strong>of</strong> focal pancreatitis involving the head or the uncinate process <strong>of</strong> the<br />

pancreas with involvement <strong>of</strong> the adjacent viscera (commonly, the pylorus <strong>of</strong> the stomach or the<br />

duodenum), the possibility <strong>of</strong> groove pancreatitis should be highly considered.<br />

Elevated Intracranial Pressure Diagnosed by Optic Ultrasound in the Setting <strong>of</strong> Normal Intraventricular<br />

Catheter Pressure Measurements.<br />

Dr. Michael Monson D.O., M.A. Dr. Anthony Nations M.D.<br />

INTRODUCTION: One <strong>of</strong> the largest obstacles for physicians treating wounded service members is<br />

measuring intracranial pressure (ICP). Intraventricular catheters have long served as the “gold standard”<br />

<strong>of</strong> measuring, but are extremely invasive and difficult to maintain. Recent studies have shown that<br />

ultrasound measurement <strong>of</strong> the optic nerve sheath diameter can be used as a noninvasive way to gauge<br />

the ICP. This includes studies by Hansen HC, Blaivas M, Tayal V, Moretti R, who have come to the<br />

conclusion that ultrasound can consistently evaluate for an increased ICP. We present the case <strong>of</strong> a<br />

wounded Marine who was diagnosed by ultrasound to have elevated ICP, in the setting <strong>of</strong> a normal<br />

intraventricular catheter pressure measurement.<br />

CASE PRESENTATION: The patient is a 20 year old previously healthy male who was injured in an<br />

explosion causing multiple penetrating cranial wounds. Prior to transfer to our facility, he had<br />

undergone multiple surgeries in Afghanistan and Germany, including a bifrontal craniectomy with<br />

intraventricular catheter placement for direct ICP monitoring. One week after arrival, the patient<br />

became acutely hypertensive and bradycardic, concerning for increasing ICP manifesting as Cushing’s<br />

Reflex. The reading from the intraventricular catheter was discordant, however, showing a normal<br />

pressure. To assess help solve this diagnostic dilemma, a bedside ultrasound was performed <strong>of</strong> the orbit,<br />

which showed a markedly dilated optic nerve sheath diameter (6.9mm with normal being less than<br />

5.2mm). The patient was taken for a stat CT <strong>of</strong> the head, which showed a significant increase in size <strong>of</strong> a<br />

previously stable intracranial hemorrhage. He was taken for arterial embolization, which he tolerated<br />

without complication. The intraventricular catheter did eventually show an elevated ICP, but not for<br />

another 2 hours.<br />

DISCUSSION: This case highlights the pr<strong>of</strong>ound usefulness <strong>of</strong> the bedside ultrasound as a diagnostic<br />

modality in patients who have suffered traumatic brain injury. As military physicians who are constantly<br />

involved with the care <strong>of</strong> the Wounded Warriors, this is a rapidly available test that can provide a great<br />

deal <strong>of</strong> information. In this patient, whose vital signs and physical exam findings were conflicting, beside<br />

ultrasound <strong>of</strong> the optic nerve sheath was able to provide information leading to a definitive diagnosis<br />

prior to the “gold standard” <strong>of</strong> direct ICP measurement. We submit this case to bring to the attention <strong>of</strong><br />

military physicians the usefulness <strong>of</strong> a bedside ultrasound <strong>of</strong> the optic nerve sheath as a means to<br />

evaluate for increased intracranial pressure.<br />

Veterans Affairs Medical Center, Salt Lake City, Utah<br />

INTRODUCTION: Drug-induced thrombocytopenia is a reversible cause <strong>of</strong> thrombocytopenia that is<br />

commonly not diagnosed. Diagnosis requires high level <strong>of</strong> clinical suspicion, correlation with the<br />

initiation <strong>of</strong> suspect drug, reversibility once the <strong>of</strong>fending drug is stopped, and, ideally, laboratory<br />

confirmation. However, routine laboratory methods <strong>of</strong> diagnosis are not readily available and the<br />

diagnosis is frequently overlooked and under-reported in literature.<br />

CASE PRESENTATION: DISCUSSION: Thrombocytopenia in the hospitalized patient has many<br />

etiologies. This case emphasizes a potentially frequently under-recognized acquired etiology for<br />

thrombocytopenia from a commonly utilized antimicrobial. High clinical suspicion and careful history<br />

taking and chart review can possibly save patients from unnecessary transfusions with associated risks<br />

as well as costly pharmaceutical interventions.<br />

Novel Therapy for Unresectable Cutaneous Squamous Cell Carcinoma in a Somali Male with<br />

Oculocutaneous Albinism<br />

INTRODUCTION: Novel Therapy for Unresectable Cutaneous Squamous Cell Carcinoma in a Somali<br />

Male with Oculocutaneous Albinism. Mitchell Nimmich, MD and Patrick Hohl, DO, MPH. University <strong>of</strong><br />

Vermont / FAHC Internal Medicine Residency Program, Burlington, VT.<br />

CASE PRESENTATION: MI is a 25 year-old black male who recently emigrated from Somalia with a past<br />

medical history significant for oculocutaneous albinism presenting for evaluation <strong>of</strong> bilateral scalp and<br />

neck masses. These originally began as small skin lesions 2-3 years prior to presentation and progressed<br />

to the point <strong>of</strong> unilateral vision impairment. He came to the United States via a Kenyan refugee camp,<br />

arriving in Nashville, TN where he was evaluated at an area hospital. Initial biopsy showed poorly<br />

differentiated carcinoma. He left that hospital shortly after presentation to pursue further workup in<br />

Vermont, where his closest family members were located. On arrival he was admitted to the oncology<br />

service and underwent a second biopsy, which showed poorly differentiated squamous cell<br />

carcinoma. CT head showed the mass extending into the external auditory canals but no skeletal or<br />

cerebral invasion. Both scalp masses appeared infected and he was initially treated with pipercillintazobactam<br />

and vancomycin. Otolaryngology and radiation oncology were consulted. Given the<br />

vascular nature <strong>of</strong> the masses and their large size, surgical resection was deemed too risky. Radiation<br />

oncology was hesitant to administer radiation therapy given his albinism and risk for inciting subsequent<br />

tumors. Staging workup with CT chest, abdomen and pelvis did not reveal metastasis. He did not show<br />

signs <strong>of</strong> systemic infection, therefore his antibiotics were changed to topical metronidazole powder with<br />

good response. He was treated with four cycles <strong>of</strong> cisplatin and cituximab with no effect on tumor size.<br />

He was treated with palliative radiation (underwent radiotherapy for two weeks with daily dose<br />

fractions <strong>of</strong> 300 Gy, total dose <strong>of</strong> 3000 Gy) and daily dexamethasone and was discharged to hospice. He<br />

showed a dramatic response to radiation and had an almost complete resolution <strong>of</strong> tumor mass. He<br />

was subsequently discharged from hospice and continues to be followed closely by oncology, radiation<br />

oncology and dermatology. He does have several new scalp lesions that appear to be novel squamous<br />

cell carcinomas in addition to multiple actinic keratoses.<br />

DISCUSSION: Cutaneous squamous cell carcinoma is a malignant proliferation <strong>of</strong> epidermal<br />

keratinocytes. Major risk factors are cumulative sun exposure (higher near the equator) and<br />

age. Oculocutaneous albinism is an independent risk factor with a 25% prevalence <strong>of</strong> non-melanoma<br />

skin cancer (including basal cell carcinoma and squamous cell carcinoma). According to NCCN<br />

guidelines, treatment <strong>of</strong> early non-invasive SCC consists <strong>of</strong> surgical resection, with radiation therapy<br />

reserved for invasive lesions or larger, non-resectable disease. Systemic chemotherapy is typically<br />

reserved for metastatic disease and an effective regimen has been gleaned from only a few small case<br />

reports. Even fewer case reports exist for invasive SCC in albino patients residing in equatorial Africa.<br />

Among this high-risk population primary treatment typically consists <strong>of</strong> surgical resection with adjuvant<br />

radiotherapy, but treatment choices are <strong>of</strong>ten influence by resource availability in these locations.<br />

Systemic chemotherapy agents, including cisplatin and more recently the newer agent cituximab, an<br />

antibody targeted against epidermal growth factor receptor (EGFR), have been used with limited<br />

success. Typically these are used to reduce tumor size so that the more effective surgical or radiation<br />

techniques can be applied.<br />

Community-acquired MRSA epidural abscess and meningitis Elizabeth Nimmich MD, Anne Bantle MD<br />

Fletcher Allen Healthcare/University <strong>of</strong> Vermont Internal Medicine Residency Program, Burlington, VT<br />

Elizabeth B Nimmich, MD Second Author: Anne Bantle, MD<br />

INTRODUCTION: Incidence <strong>of</strong> community-acquired methicillin-resistant Staphylococcus aureus (CA-<br />

MRSA) has increased since its first description in the literature in the 1980s. Less common are reports <strong>of</strong><br />

CA-MRSA with central nervous system (CNS) involvement, with only a small number <strong>of</strong> cases published<br />

since 1999. Given the restrictive permeability <strong>of</strong> the blood-brain-barrier to certain antibiotics, treatment<br />

<strong>of</strong> CNS CA-MRSA infections can pose a significant challenge. Unfortunately, these infections also carry a<br />

considerably high mortality.<br />

CASE PRESENTATION: A 25 year old woman with past medical history significant for intravenous<br />

heroin abuse presented with a 2-3 day history <strong>of</strong> progressively worsening neck and back pain and a one<br />

day history <strong>of</strong> dyspnea and fever. Pertinent physical exam findings included temperature <strong>of</strong> 38.1°C,<br />

pulse 140, hypoxia on room air, left-sided paraspinal muscle tenderness to palpation, positive Kernig’s<br />

sign, and left-sided neck swelling and erythema. She was empirically started on ceftriaxone 2 g IV BID,<br />

vancomycin 15 mg/kg IV TID, and gentamicin 1mg/kg IV TID. A lumbar puncture was performed and was<br />

notable for an opening pressure <strong>of</strong> 35 mmHg, WBC 230 with 98% neutrophils, protein 406, and glucose<br />

49. MRI spine showed an epidural abscess extending from C7 to T7. Debridement <strong>of</strong> the epidural<br />

abscess was planned. Blood cultures grew MRSA in 3/4 bottles. She continued to decline with rapidly<br />

dropping platelet count, hypotension despite multiple vasopressors, and worsening hypoxia on<br />

mechanical ventilation. On hospital day two, she developed wide-complex tachycardia, then pulseless<br />

electrical activity, and expired despite resuscitative efforts with ACLS protocol.<br />

DISCUSSION: This case represents the high mortality associated with hematogenous spread <strong>of</strong> CA-<br />

MRSA to CNS. Though there are only a small number <strong>of</strong> similar cases reported in the literature, this may<br />

represent a rise in severe CA-MRSA infection, similar to the trend with hospital-acquired MRSA in the<br />

recent past. CA-MRSA has already been identified as the most common cause <strong>of</strong> skin and s<strong>of</strong>t-tissue<br />

infections in the emergency department. Treatment <strong>of</strong> severe CA-MRSA infection can be challenging,<br />

and in early 2011 the Infectious Diseases Society <strong>of</strong> America’s new MRSA treatment guidelines added<br />

linezolid and trimethoprim-sulfamethoxazole as alternatives to vancomycin for MRSA meningitis.<br />

Vancomycin remains first-line therapy, but its reduced penetration through the blood-brain-barrier<br />

limits is utility in cases such as this one. Interestingly, there are cases in the literature that show less<br />

mortality associated with linezolid treatment. Given the smaller number <strong>of</strong> reports, this data is largely<br />

anecdotal but poses a fascinating question over the appropriate antimicrobial selection in CA-MRSA CNS<br />

infections and necessitates further evaluation.<br />

Intrathecal Methotrexate Nephrotoxicity<br />

Vince Faridani MD, Jim Mertz MD<br />

INTRODUCTION: We are reporting a patient who presented with acute renal failure secondary to<br />

intrathecal methotrexate administration for treatment <strong>of</strong> acute lymphoblastic leukemia (ALL). This<br />

occurred despite normal renal function prior to methotrexate (MTX) initiation and vigorous hydration<br />

with urinary alkalinization during treatment.<br />

CASE PRESENTATION: A 47 year-old Hispanic gentleman presented to our hospital complaining <strong>of</strong><br />

generalized fatigue and lower extremity rash. Laboratory data disclosed a complete blood cell count<br />

with a WBC <strong>of</strong> 1.6, PLT < 61,000, HCT 40.9%, HGB 14.4 g/dl. Serum urea was 14 mg/dl, serum creatinine<br />

.9 mg/dL, sodium 134 mmol/L and bicarbonate 27 mmol/L. Bone marrow biopsy showed a hypercellular<br />

bone marrow (90%) and left shift with increased blast cells (nearly 100%) compatible with ALL. Our<br />

patient received his second course <strong>of</strong> cyclophosphamide, vincristine, doxorubicin and dexamethasone<br />

and intrathecal methotrexate. The following day creatinine increased to 2.5mg/dl, serum uric acid level<br />

was 10.6 mg/dL, methotrexate level was 23.56 µM. Thus confirming our suspicion <strong>of</strong> tumor lysis<br />

syndrome. He was treated with intravenous hydration, alkalinization <strong>of</strong> the urine, and supportive<br />

therapy with intensive leucovorin for 12 days. The patients renal function slowly improved, creatinine<br />

returned to baseline and methotrexate and uric acid level returned to normal.<br />

DISCUSSION: This is the 2 nd case report that illustrates a previously unrecognized potential<br />

complication <strong>of</strong> intrathecal methotrexate -- acute tumor lysis syndrome. Despite normal baseline<br />

creatinine clearance and adherence to standard precaution to prevent renal toxicity with hydration and<br />

alkalinization, severe renal toxicity may occur secondary to tymor lysis syndrome. Development <strong>of</strong> acute<br />

renal failure during methotrexate therapy is a medical emergency, since more than 90% MTX is cleared<br />

by the kidneys, renal failure contributes to the sustained toxic levels <strong>of</strong> MTX. If not treated early and<br />

aggressively, methotrexate can damage the ability <strong>of</strong> normal cells to synthesize DNA leading to cell<br />

death and resulting in renal, hepatic, and central nervous system toxicity. As this case illustrates, even<br />

with intrathecal methotrexate toxicity, treatment with pharmacologically guided leucovorin rescue<br />

along with continuation <strong>of</strong> hydration and alkalinization will facilitate restoration <strong>of</strong> renal function and<br />

decrease the risk <strong>of</strong> impending systemic toxicity.<br />

A RARE CASE OF FALSELY ELEVATED THYROTROPIN(TSH)LEVEL DUE TO HETEROPHILE ANTIBODY<br />

LT Manoj Mathew, MD<br />

INTRODUCTION:Subclinical hypothyroidism, which is defined as elevated serum thyrotropin (TSH) and<br />

normal serum free thyroxine (FT4) levels, is common clinical in practice. Patients with subclinical<br />

hypothyroidism and TSH concentration above 10 mIU/L are usually treated with thyroid hormone<br />

supplement. We hereby present a case in which heterophile antibodies interfere with the TSH assay,<br />

leading to a falsely elevated TSH level and unnecessary thyroid hormone therapy.<br />

CASE PRESENTATION: A 41 year-old female presented to her primary care physician (PCP) for an<br />

annual physical examination. She reported no fatigue, temperature intolerance, or changes in her skin,<br />

hair, or bowel habits. She had normal menstrual cycles and stable weight. The thyroid gland was normal<br />

in size and without nodules. However, a screening thyroid panel (TFT) showed serum TSH level<br />

19.6mIU/L (normal 0.465-4.680) and FT4 level 1.46ng/dL (normal 0.64-1.79). She was diagnosed with<br />

subclinical hypothyroidism and started on levothyroxine treatment. Even though she was compliant with<br />

the therapy, the TSH level remained elevated. Her PCP gradually increased the levothyroxine dosage to<br />

300mcg daily. She subsequently developed palpitations and tremor and was referred to endocrinology<br />

for further evaluation. Repeated laboratory study showed FT4 2.91ng/dL, FT3 1.7ng/mL (normal 0.970-<br />

1.690), and TSH 17.7mIU/L. A Cosyntropin stimulation test showed the peaked cortisol level <strong>of</strong><br />

26.6mcg/dL (normal >18). TSH heterophile antibody was present. Endocrinology tapered and eventually<br />

discontinued the levothyroxine treatment. The palpitations and tremor resolved. Subsequent study<br />

showed TSH 22.9mIU/, FT3 1.11ng/mL, and FT4 0.80ng/mL. The TSH dilution test showed serum TSH<br />

levels 15.2 mIU/L initially and 5.2 mIU/L after a five-fold dilution. With mouse serum pretreatment, the<br />

TSH level was 1.19 mIU/L.<br />

DISCUSSION: The differential diagnosis for elevated serum TSH with normal FT4 and FT3 includes<br />

subclinical hypothyroidism, resistance to TSH, a TSH-secreting pituitary adenoma, untreated adrenal<br />

insufficiency, and interfering substances. In our patient, subclinical hypothyroidism is unlikely given that<br />

the TSH level never normalizes despite gradual increases in the levothyroxine dosage. Resistance to<br />

thyroid hormone is unlikely given the normal TSH level in 2007 and absence <strong>of</strong> family history <strong>of</strong> thyroid<br />

disease. A TSH secreting pituitary adenoma is also unlikely given the normal FT4 and FT3 levels and<br />

absence <strong>of</strong> a thyroid goiter. Normal Cosyntropin stimulation makes adrenal insufficiency less likely.<br />

The elevated TSH level in this patient is caused by human anti-mouse monoclonal antibodies (HAMA).<br />

The TSH value normalizes when the serum is pretreated with mouse serum. HAMA, also known as<br />

heterophile antibody, can interfere with TSH immunoassays, causing falsely elevated TSH values. Many<br />

laboratories have HAMA-blocking reagents that can eliminate the interference <strong>of</strong> heterophile<br />

antibodies.<br />

Heterophile antibody interference with TSH immunoassay should be on the differential diagnosis <strong>of</strong><br />

asymptomatic patients with elevated TSH concentration. Evaluation for this condition may prevent<br />

unnecessary thyroid hormone treatment.<br />

CASE PRESENTATION: Case: Mr. G is a 28 yo White male with no significant PMH who presented to the<br />

ER during June with complaint <strong>of</strong> substernal chest pain for 3 days at rest, with no radiation, describe it as<br />

a sharp pain, rate it 7/10, lasting for about 15 seconds with some residual soreness for 20-30 minutes.<br />

Patient denied CP on exertion, deep inspiration or position changes. He also complained <strong>of</strong> shortness <strong>of</strong><br />

breath <strong>of</strong> same duration, associated with exertion. Pt worked as grounds keeper at a golf course and<br />

A High Tech Source <strong>of</strong> Ethylene Glycol Toxicity<br />

Bonny Lauren Moore, MD Jadyn Swerbinsky, PA; James Cain, MD; Chad Demott, MD, FACP<br />

INTRODUCTION:The patient's history <strong>of</strong> present illness is <strong>of</strong>ten the most important factor in making a<br />

diagnosis. However, when a patient will not or cannot provide an accurate history, the differential<br />

diagnosis must remain wide and empiric therapies <strong>of</strong>ten initiated without a firm diagnosis.<br />

CASE PRESENTATION: A 20 yo man with no past medical history was admitted with vomiting, loss <strong>of</strong><br />

balance, and diplopia. He reported feeling well the night prior to presentation. He denied any ingestions<br />

or inhalant use.<br />

He presented afebrile with unremarkable vital signs. Neurologically, he exhibited truncal and peripheral<br />

ataxia, bilateral dysmetria, and slowed speech with horizontal nystagmus on left gaze. Otherwise,<br />

physical exam was unremarkable. At the outside hospital, BMP revealed a bicarb level <strong>of</strong> 11, chloride <strong>of</strong><br />

113, and BUN <strong>of</strong> 13. Initial creatinine <strong>of</strong> 1.09 and anion gap <strong>of</strong> 15 subsequently increased to 1.81 and 19.<br />

Initial ABG showed pH <strong>of</strong> 7.21, pCO2 <strong>of</strong> 20 and pO2 <strong>of</strong> 118. CBC, creatine kinase, ammonia, and routine<br />

toxicology were unremarkable. Serum ketones were not present. Imaging <strong>of</strong> head, abdomen, and pelvis<br />

were unremarkable except for a distended bladder on CT. He had an osmolar gap <strong>of</strong> 30. Urine did not<br />

fluoresce under Wood's lamp and the lab reported no calcium oxalate crystals, although on our exam,<br />

calcium oxalate monohydrate crystals were present. Given the presentation, empiric fomepizole,<br />

sodium bicarbonate, and CRRT were started. Ethylene glycol level drawn at our facility returned positive<br />

at 12 mcg/mL. Other alcohol levels returned undetectable. The patient required hemodialysis for one<br />

week before recovery.<br />

He continued to deny toxic ingestions, even after a search <strong>of</strong> his bedroom revealed an open container <strong>of</strong><br />

computer coolant with a primary ingredient <strong>of</strong> ethylene glycol.<br />

DISCUSSION: This case represented a diagnostic challenge: mixed metabolic acidosis with osmolar gap,<br />

denial <strong>of</strong> ingestion, neurological complaints, and unusual findings on urinalysis. Calcium oxalate<br />

monohydrate crystals are not as common as the dihydrate crystals, but can be detected in ethylene<br />

glycol poisoning and are known to resemble picket fences as they are long, flat, hexagonal crystals.<br />

While this case illustrates many important learning points, it is crucial to recognize the stages and<br />

varieties <strong>of</strong> presentation for ethylene glycol poisoning.<br />

Ethylene glycol is widely recognized as an ingredient in antifreeze for automobiles, but it is contained in<br />

many common household products, such as computer coolant. This presentation is unusual as the<br />

patient did not have a history <strong>of</strong> alcohol use or prior intoxication. To our knowledge, this is the first<br />

reported case <strong>of</strong> ethylene glycol poisoning by computer coolant ingestion. Because <strong>of</strong> its wide<br />

accessibility, early recognition and treatment <strong>of</strong> ingestion is critical.<br />

Cafe Au Lait With A Side Of Multiple Sclerosis<br />

Seth T Parsons, MD Second Author: Sami G Tahhan, MD, FACP<br />

INTRODUCTION: CASE PRESENTATION: A 32 y/o man came to the hospital with a two and a half<br />

month history <strong>of</strong> worsening ataxia, limb numbness, tingling, weakness, diplopia and blurry vision. He<br />

attested to multiple falls and had a positive Uhth<strong>of</strong>f’s sign. On exam, the patient had countless<br />

cutaneous neur<strong>of</strong>ibromas and café au lait spots. His cognitive function was slow and his speech was<br />

slurred. MRI <strong>of</strong> the head and c-spine showed extensive cerebral, brainstem and cerebellar white matter<br />

abnormalities with numerous enhancing lesions and extensive cord to upper thoracic cord signal<br />

abnormalities consistent with multiple sclerosis. MRI <strong>of</strong> the orbits showed optic neuropathy also<br />

consistent with multiple sclerosis. He was given 1 gram per day <strong>of</strong> methylprednisolone for five days and<br />

received physical and occupational therapy which improved his strength and coordination.<br />

DISCUSSION: Neur<strong>of</strong>ibromatosis type 1 is a common autosomal-dominant neurocutaneous disorder<br />

associated with café-au-lait spots, Lisch nodules, neur<strong>of</strong>ibromatous tumors, and other pleotropic<br />

conditions. Mutations <strong>of</strong> NF1 (a tumor suppressor gene located on chromosome 17q11.2) cause<br />

functional loss <strong>of</strong> the protein neur<strong>of</strong>ibromin, resulting in a wide-spectrum <strong>of</strong> the above said conditions.<br />

Multiple Sclerosis is the most common autoimmune inflammatory demyelinating disease <strong>of</strong> the CNS,<br />

characterized by multifocal areas <strong>of</strong> demyelination, astroglial scarring and loss <strong>of</strong> oligodendrocytes. It is<br />

hypothesized that a genetic predisposition coupled with environmental triggers produces antibodies<br />

directed against myelin, causing demyelination and a plethora <strong>of</strong> neurologic manifestations.<br />

Reports have shown that the prevalence rates <strong>of</strong> Neur<strong>of</strong>ibromatosis and Multiple Sclerosis co-existing<br />

together are 15 times higher than expected separately. Theories for this association include: The NF1<br />

gene encodes an important tumor suppressor protein called neur<strong>of</strong>ibromin. Neur<strong>of</strong>ibromin functions as<br />

a suppressor by reducing cell proliferation through the p21 ras protein system. In NF1 patients, lack <strong>of</strong><br />

this crucial suppressor could result in over-proliferation, causing over-activity <strong>of</strong> the immune system and<br />

abs against myelin. A second hypothesis involves oligodendrocyte myelin glycoprotein (OMgp) which is<br />

embedded within intron 27b <strong>of</strong> the NF1 gene A. Oligodendrocyte myelin glycoprotein is essential for<br />

myelination and the survival <strong>of</strong> myelinated axons. Any disruption to this gene could make it a target by<br />

the immune system in genetically-predisposed MS patients, resulting in a massive demyelination<br />

process. A third hypothesis involves Schwann cells which create myelin. Since NF1 is a proliferative<br />

disorder involving these cells, it could be that overproduction <strong>of</strong> myelin causes an immune response<br />

with ab production which then activates a similar response to CNS myelin.<br />

More research is needed to clarify the causal relationship between MS and NF1, but this case illustrates<br />

an interesting association.<br />

increasingly recognized as a cause <strong>of</strong> Acquired Fanconi's Syndromre in HIV infected individuals. Several<br />

case reports <strong>of</strong> acute renal failure and proximal tubulopathy have been reported with ten<strong>of</strong>ovir use<br />

since the first case report in 2003. We report a case <strong>of</strong> Fanconi's Syndrome that developed after more<br />

than 8 years <strong>of</strong> ten<strong>of</strong>ovir and reversed upon discontinuation.<br />

CASE PRESENTATION: The patient is a 56 yo African <strong>American</strong> male with a CD4 <strong>of</strong> 616 cells/mm3 and<br />

HIV RNA <strong>of</strong> 825 on emitricitabrine, ten<strong>of</strong>ovir (started in 12/2002), atazanavir (started 1/2004). He<br />

developed muscle weakness and presented with acute renal failure on admission on 7/1/11 with<br />

creatinine <strong>of</strong> 2.6, GFR 34 (baseline 4/19/11 creatinine <strong>of</strong> 1.6, GFR 55 and stable since 2001) and with<br />

glucosuria (1000 mg/dL with normal serum glucose), hypophosphatemia (Phos 1.0), hypokalemia<br />

(potassium 2.9), proteinuria (100 mg/dL), serum uric acid 0f 1.7 mg/dl, urine creatinine <strong>of</strong> 22 mg/dl and<br />

urine uric acid <strong>of</strong> 14 mg/dL. These are classic features <strong>of</strong> Acquired Fanconi Syndrome. Metabolic Acidosis<br />

was not present due to concomitant metabolic alkalosis from emesis. On discontinuation <strong>of</strong> ten<strong>of</strong>ovir<br />

and replacement <strong>of</strong> electrolytes, clinical improvement with near normalization <strong>of</strong> electrolytes and return<br />

<strong>of</strong> creatinine to baseline was seen within 5 weeks.<br />

DISCUSSION: With ten<strong>of</strong>ovir so commonly used in the treatment <strong>of</strong> HIV, urinalysis, renal and electrolyte<br />

monitoring at regular intervals following its initiation should be considered. Current guidelines<br />

recommend adjusting the ten<strong>of</strong>ovir dose with CrCl < 49 mL/min., which this patient did not manifest<br />

prior to developing Fanconi's syndrome. Given our experience with this patient, changing to a different<br />

antiretroviral might be considered rather than continuing ten<strong>of</strong>ovir or adjusting the dose if renal<br />

insufficiency develops to decrease the risk <strong>of</strong> acquired Fanconi's syndrome. And also noted is that some<br />

people assume Ten<strong>of</strong>ovir induced fanconi's happens few months after initiation <strong>of</strong> therapy (avg 5<br />

months) but this case shows that it can happen anytime (8 years later)<br />

Radial Artery Sterile Granulomatous Reaction<br />

Om Samantray, MD Dexter De Leon M.D Gary Swank M.D M. Ayoub Mirza M.D<br />

INTRODUCTION: Trans-radial cardiac catheterization was introduced in late 1980s and since then has<br />

become increasingly popular due to lower risk <strong>of</strong> vascular complication, better patient comfort, lower<br />

procedure costs and lesser duration <strong>of</strong> hospitalization. Despite all these advantage there are some<br />

reported cases <strong>of</strong> radial artery granulomatous reaction associated with radial artery catherization. We<br />

are presenting a case <strong>of</strong> radial artery granulomatous formation after trans-radial cardiac catheterization<br />

CASE PRESENTATION: 55 year old male referred for diagnostic cardiac catheterization due to chest<br />

pain which resulted in an abnormal myocardial perfusion scan demonstrating inferior wall ischemia. A<br />

trans-radial cardiac catheterization was performed using a 5F Cook hydrophilic sheath. At the end <strong>of</strong> the<br />

procedure a radial compression device was applied for hemostasis. Two weeks later, patient presented<br />

with a painful erythematous, indurated, fluctuant nodule over the radial artery access site. He did not<br />

have any signs or symptoms <strong>of</strong> systemic infection. He saw a dermatologist who performed incision and<br />

drainage <strong>of</strong> purulent fluid. The fluid grams stain and culture was negative. Vascular duplex ultrasound <strong>of</strong><br />

radial artery was normal. He was treated with Prednisone 30mg daily for 5 days. There was complete<br />

resolution within 3 weeks.<br />

DISCUSSION: In the early years <strong>of</strong> cardiac angiography, most procedures were done through brachial<br />

cut downs. In 1989, Campeau proposed Trans-radial approach for cardiac catheterization. Trans-radial<br />

access is associated with lower vascular and bleeding complications and allows early patient ambulation.<br />

The leading drawback to this approach is arterial vasospasm. To overcome vasospasm, a hydrophilic<br />

lubricated catheter was introduced. Rathore et al. reported that this hydrophilic coating is effective in<br />

reducing spasm and reduced patient discomfort.<br />

Despite all <strong>of</strong> these advantages there are several reported case <strong>of</strong> sterile granulomatous reaction. Sterile<br />

granulomas were commonly misdiagnosed as an infected pseudoaneurym, thrombosis or abscesses<br />

leading to untoward surgeries and antibiotic treatments. Biopsy <strong>of</strong> these lesions reveals a suppurative<br />

granulomatous reaction with macrophages containing a blue gray substance on stain microscopy. These<br />

sterile abscess and granulomas typically have a benign course and in the absence <strong>of</strong> fever and<br />

leukocytosis, the recommendation is observation. Since the cook hydrophilic sheaths were replaced in<br />

our cardiac catherization lab and we have not seen any further cases <strong>of</strong> sterile granuloma <strong>of</strong> the radial<br />

artery. The authors believe the sterile granuloma appear due to a foreign body reaction from the<br />

deposition <strong>of</strong> the hydrophilic gel in the subcutaneous tissues during placement or removal <strong>of</strong> the sheath.<br />

THIAZIDE DIURETICS: YOU MAY NEED A LITTLE SALT WITH THAT<br />

Kristyn M Sayball, DO, Associate Member, Virginia Commonwealth University Health Systems<br />

INTRODUCTION:Thiazide diuretics are one <strong>of</strong> the most common medications used in the management<br />

<strong>of</strong> hypertension and are assumed to be relatively benign. However, they can cause significant side<br />

effects<br />

CASE PRESENTATION: A 66 year old female with HTN visiting family from India was brought to the ER<br />

with several days <strong>of</strong> nausea and vomiting and the acute onset that morning <strong>of</strong> confusion, weakness, and<br />

slurred speech. Past medical history is only significant for HTN for which she was taking Atenolol,<br />

Chlorthalidone, and Ramipril; she had been started on Chlorthalidone approximately three months prior<br />

to presentation after complaining <strong>of</strong> lower extremity swelling with Amlodipine. Her blood pressure<br />

was136/80, heart rate 67, temperature 36.9C, and she was 98% on RA with a respiratory rate <strong>of</strong> 16.<br />

Physical exam was pertinent for an alert female oriented to person only but with no other focal<br />

neurological deficits. Lab revealed a WBC count <strong>of</strong> 22,000, a serum sodium <strong>of</strong> 99, potassium <strong>of</strong> 2.7,<br />

chloride <strong>of</strong> 59, bicarbonate <strong>of</strong> 27, BUN <strong>of</strong> 9, and creatinine <strong>of</strong> 0.5. Her hepatic panel revealed an AST <strong>of</strong><br />

68 but was otherwise within normal limits. Head CT was negative for acute findings. She was admitted<br />

to the medical ICU for management <strong>of</strong> symptomatic severe hyponatremia. Given her relatively stable<br />

mental status despite severe electrolyte derangement she was given normal saline at 150mL/hr rather<br />

than administering hypertonic saline. The assumption was that the drop in sodium was chronic with a<br />

superimposed acute decrease due to gastrointestinal symptoms. Her urine electrolytes (urine sodium <strong>of</strong><br />

35, urine osm <strong>of</strong> 372) were consistent with diuretic induced hyponatremia. Serial repeats <strong>of</strong> these<br />

values <strong>of</strong>f diuretics over the next several days showed an expected decline in the urine sodium to < 10<br />

and <strong>of</strong> the urine osmolality to around 250. With the above treatment the sodium level rose gradually<br />

over the next 48 hours. Her mental status returned to baseline. Notably, discussion with the family<br />

revealed a history <strong>of</strong> stict adherence to her low salt diet, recommended by her physician, likely<br />

contributing to her presentaion. All other investigation into the etiology <strong>of</strong> hyponatremia was<br />

unrevealing.<br />

DISCUSSION: Diuretic therapy is a common cause <strong>of</strong> hyponatremia, a condition <strong>of</strong>ten resulting in<br />

critical illness and at times death. Among cases <strong>of</strong> hyponatremia attributed to diuretics, thiazides are<br />

the most common class, accounting for as many as 94%. This case illustrates the severe degree <strong>of</strong><br />

hyponatremia and electrolyte derangement that can result from commonly prescribed diuretics and the<br />

importance <strong>of</strong> consistent electrolyte monitoring.<br />

THE QUESTION TO LYSE: NOT JUST FOR THE SCHOOL NURSE<br />

Kristyn M Sayball, DO, Associate Member, Virginia Commonwealth University Health Systems<br />

INTRODUCTION:While there are published guidelines on the use <strong>of</strong> systemic thrombolytics in acute<br />

clot, the decision on when to use them is not always easy.<br />

CASE PRESENTATION: A 68 year old male presented to the emergency department complaining <strong>of</strong><br />

dyspnea, pr<strong>of</strong>ound diarrhea, and weakness. He had been discharged eight days earlier after open<br />

gastrostomy tube placement for an esophageal stricture; the procedure was complicated by a possible<br />

liver laceration. Initial vitals on this presentation were significant for a blood pressure <strong>of</strong> 94/71, heart<br />

rate <strong>of</strong> 126, respiratory rate <strong>of</strong> 22, and hypoxia requiring 100% oxygen via a nonrebreather mask.<br />

Physical exam was pertinent for an elderly male in moderate respiratory distress. Cardiovascular exam<br />

showed a regular rhythm without murmurs, lungs were clear to auscultation, abdomen was s<strong>of</strong>t with<br />

mild tenderness around the gastrostomy tube, and his extremities were cool to touch. Due to the recent<br />

prolonged hospitalization and the above physical exam findings, we had a high suspicion for pulmonary<br />

embolism; however, acute renal failure (serum creatinine <strong>of</strong> 1.88 mg/dL) prevented a CT angiogram. An<br />

emergent transthoracic echocardiogram was performed which showed a 3 cm x 3 cm free floating right<br />

atrial thrombus with right ventricular dilation and flattening <strong>of</strong> the left ventricular septum. The patient<br />

was immediately started on a heparin drip; however, there was concern that this alone would not be<br />

adequate. Both interventional radiology and cardiothoracic surgery were consulted for embolectomy or<br />

thrombectomy <strong>of</strong> the atrial clot; however, given his clinical condition both consultants recommended<br />

continued clinical management. In considering systemic thrombolytics, the team weighed the relative<br />

contraindication <strong>of</strong> a recent open surgery with potential liver laceration. Of additional concern was the<br />

possibility that thrombolytics would cause the thrombus to break up and migrate through the tricuspid<br />

valve, increasing the clot burden in the lungs and further increasing afterload on an already failing right<br />

ventricle. After a thorough review <strong>of</strong> the literature and extensive discussions with the patient regarding<br />

the risks and benefits, the decision was made to administer thrombolytics. The patient showed<br />

immediate improvement in both his hemodynamics and dyspnea. A bedside ultrasound later that<br />

afternoon showed complete resolution <strong>of</strong> the right atrial thrombus.<br />

DISCUSSION: This case presents the common problem <strong>of</strong> pulmonary embolus complicated by<br />

additional thrombus in transit. Though rare, right atrial thrombus is associated with high<br />

mortality. Systemic thrombolytics are associated with a high incidence <strong>of</strong> bleeding, a risk increased with<br />

recent invasive procedures. The use <strong>of</strong> lytic therapy in this case resulted in a favorable outcome, similar<br />

to the few reported cases in the medical literature.<br />

Severe Hyperammonemic Encephalopathy After Gastric Bypass: A Case Of The Missing Zinc.<br />

First Author: Kenneth H Surkin, MD Second Author: Mark Flemmer, MD<br />

Introduction : Nutritional deficiencies are a common complication <strong>of</strong> gastric bypass surgery. Rarely,<br />

these nutritional deficiencies can lead to neurological complications and encephalopathy. Zinc<br />

deficiency is an uncommon and <strong>of</strong>ten unrecognized nutrient deficiency in these patients.<br />

Case Presentation: A 32-year-old, HIV positive, African <strong>American</strong> female presented with suicidal<br />

ideation and altered mental status. She underwent gastric bypass surgery 1 year prior to admission. She<br />

had extremely poor nutritional intake since the surgery and no medical follow up. After initial admission<br />

to psychiatry for presumed major depressive disorder, her condition deteriorated and she required ICU<br />

admission for hypotension and unresponsiveness. Initial lab-work revealed moderate transaminitis,<br />

hypoalbuminemia, and an extremely elevated ammonia level <strong>of</strong> 422. Ultrasound <strong>of</strong> the liver revealed<br />

only mild steatosis without evidence <strong>of</strong> cirrhosis and MRI <strong>of</strong> the brain was normal. Further lab-work<br />

revealed pr<strong>of</strong>ound nutritional deficiency with low levels <strong>of</strong> vitamins A, C, D, K and B6. Levels <strong>of</strong> folate<br />

and vitamin B12 were normal. Micronutrient analysis revealed severe zinc deficiency with a level <strong>of</strong> 34<br />

(range 70-110) and low serum copper. She was started on a regimen <strong>of</strong> lactulose, neomycin, and<br />

rifaximin for presumed hepatic encephalopathy and oral vitamin repletion was begun. Her<br />

cardiovascular and neurologic status improved and she was transferred from the ICU with persistently<br />

elevated ammonia <strong>of</strong> 245. Her neurologic status deteriorated within 24 hours and her ammonia level<br />

peaked at 683 requiring emergent hemodialysis. At this point, a diagnosis <strong>of</strong> an inborn error <strong>of</strong><br />

metabolism was entertained. Urine organic acid analysis revealed elevated orotic acid level <strong>of</strong> 3.18<br />

(range 0.4-1.2). Plasma amino acid analysis showed elevated glutamine, lycine, glycine, and proline with<br />

normal levels <strong>of</strong> carnitine and citrulline, consistent with hyperammonemia due to OTC deficiency. She<br />

was started on IV sodium benzoate/phenylacetate to scavenge ammonia, IV zinc, and a low protein diet.<br />

Over the next 72 hours her neurologic status improved remarkably. A direct correlation was noted<br />

between her improved serum zinc level and the normalization <strong>of</strong> her serum ammonia. She was<br />

discharged on a specialized diet and has recovered well. Subsequent genetic analysis did not reveal<br />

mutations in the ornithine transcarbamylase gene, however these mutations are absent in up to 30% <strong>of</strong><br />

patients X-linked OTC deficiency.<br />

Discussion: This case illustrates the dramatic neurologic complications that can result from nutritional<br />

deficiencies following gastric bypass. While deficiency <strong>of</strong> zinc is rare, it is an essential co-factor for the<br />

hepatic ornithine transcarbamylase (OTC) enzyme. X-linked OTC deficiency is usually asymptomatic but<br />

in times <strong>of</strong> severe metabolic stress, such as nutritional deficiency, this disorder can be unmasked leading<br />

to severe neurologic sequelae. With gastric bypass surgery becoming more common, clinicians should<br />

recognize zinc deficiency as a potential cause <strong>of</strong> OTC deficiency in these patients with refractory<br />

hyperammonemia and encephalopathy.<br />

ESOMEPRAZOLE-INDUCED ACUTE INSTERSTITIAL NEPHRITIS<br />

Janki Shah, MD, Associate Christy Fagg, DO, Associate Jon Sweet, MD, FACP Ann Peters. Virginia Tech<br />

Carilion School <strong>of</strong> Medicine, Roanoke, VA<br />

INTRODUCTION:Acute interstitial nephritis (AIN) is an important cause <strong>of</strong> renal failure classically<br />

associated with fevers, rash, arthralgias, eosinophiluria, eosinophilia, sterile pyuria, and white blood cell<br />

(WBC) casts. Unfortunately, these clinical and laboratory findings have very limited diagnostic utility.<br />

Non-steroidal anti-inflammatory drugs (NSAID), antibiotics, and certain infections have historically been<br />

the most commonly implicated causes <strong>of</strong> AIN. However, the very frequent use <strong>of</strong> proton pump inhibitors<br />

(PPI) seems to be an increasing cause <strong>of</strong> this problem.<br />

CASE PRESENTATION: A 54-year-old woman developed fatigue, confusion, and anorexia over 2 weeks.<br />

Her medical history included hypertension, depression, and heartburn. Her medications were lisinoprilhydrochlorothiazide,<br />

citalopram, and buspirone. She was recently started on esomeprazole. She denied<br />

recent use <strong>of</strong> NSAID or antibiotics, radiocontrast exposure, infections, or history <strong>of</strong> injuries, intravenous<br />

drug use, transfusions, hepatitis, rash, fever, lupus, or arthralgias. There was no personal or family<br />

history <strong>of</strong> kidney disease. Blood pressure was 146/79 mm Hg, but the rest <strong>of</strong> vital signs were normal.<br />

She was drowsy, oriented to person and place, and had slight asterixis with a non-focal neurological<br />

exam. The BUN was 102 mg/dL, creatinine 10.8 mg/dL, potassium 6.1 mmol/L, sodium 129 mmol/L,<br />

phosphorus 10.0 mg/dL, WBC 12,200/mm3, and hemoglobin 12.4 g/dL. Urine was cloudy with numerous<br />

WBC, moderate RBC, no casts or crystals, and grew >100,000 colonies/mL <strong>of</strong> Streptococcus agalactiae<br />

Group B. The fractional excretion <strong>of</strong> sodium was 14.9% and the urine protein/creatinine ratio was 1492<br />

mg/g. Renal ultrasonography was unremarkable. All medications were discontinued and isotonic<br />

crystalloids were administered. Tests for the following were negative/normal: C3, C4, CH50, CK, ANA,<br />

ANCA, ASO, anti-GBM antibody, hepatitis C, hepatitis B, HIV, urine eosinophils, and urine myoglobin. She<br />

required dialysis for her uremic symptoms, but her renal function failed to improve. A kidney biopsy on<br />

day 10 revealed severe AIN. Prednisone 60 mg daily was started with a prompt and sustained<br />

improvement in her kidney function.<br />

DISCUSSION: It is important for internists to be aware that AIN rarely presents with the classic triad <strong>of</strong><br />

fever, rash, and arthralgia. Our patient had none <strong>of</strong> these symptoms. She did have pyuria, but patients<br />

with AIN would generally have sterile pyuria with WBC casts. Since the sensitivity and positive predictive<br />

value <strong>of</strong> eosinophiluria for diagnosing acute interstitial nephritis are only approximately 25% and

FATAL RAOULTELLA PLANTICOLA PERITONITIS<br />

Angela D Venuto-Ashton, MD Second Author: Jon Sweet, MD<br />

INTRODUCTION: Several organisms have been reported to cause peritonitis, commonly E.Coli,<br />

Anaerobes, Streptococci, Enterococci and Clostridia. This is the first case report citing Raoultella<br />

Planticola as a pathogenic organism causing Acute Bacterial Peritonitis.<br />

The following describes a case <strong>of</strong> peritonitis caused by Raoultella Planticola that was diagnosed w/ the<br />

VITEK-2 system.<br />

CASE PRESENTATION: A 61-year-old man with a history <strong>of</strong> hypertension and alcoholism complained <strong>of</strong><br />

progressing nausea, emesis and abdominal swelling for 6 months. Forty-five days before admission he<br />

saw his physician. A comprehensive metabolic panel was normal except for an albumin <strong>of</strong> 2.6g/dL, AST<br />

112 IU/L(10-42), and total bilirubin 7.1mg/dL. The serum urea nitrogen and creatinine were 8 and 0.9<br />

mg/dL, respectively, and ALT was normal. Twelve days before admission he underwent an ultrasoundguided<br />

abdominal paracentesis which yielded 6.5L <strong>of</strong> sterile, clear yellow fluid. There were 60<br />

leukocytes/mm3, 2% <strong>of</strong> which were neutrophils. The fluid albumin and protein concentrations were<br />

below the limit <strong>of</strong> detection.<br />

On day <strong>of</strong> admission, he was alert, oriented, in no distress, afebrile, with a blood pressure <strong>of</strong> 108/46 mm<br />

Hg and heart rate 104. The cardiopulmonary examinations were normal and there was obvious<br />

ascites. The urea nitrogen and Cr were now 71 and 5.8 mg/dL, respectively, and the venous lactic acid<br />

was 5.6 mmol/L(0.5-2.2). Sixty mL <strong>of</strong> dark turbid ascitic fluid was removed and ceftriaxone, albumin,<br />

octreotide and midodrine were administered. The fluid contained 1,361 leukocytes/mm3, 47% <strong>of</strong> which<br />

were neutrophils, and grew Raoultella planticola sensitive to 14 antibiotics and resistant only to<br />

ampicillin. Blood cultures were sterile. Renal function continued to decline and intermittent<br />

hemodialysis was started on day 5. He failed to show any improvement, a palliative approach was<br />

adopted 3 days later, and he died soon thereafter.<br />

DISCUSSION: The organism’s previous classification was Klebsiella subtype. Raoultella Planticola is a<br />

rare but emerging human pathogen that correlates with infection and may prove fatal as evidenced by<br />

this case study. Per case-reports it has infrequently been suggested as a human pathogen; which<br />

include: Pancreatitis, s<strong>of</strong>t tissue infection and most recently, a surgical site infection .<br />

Our organism was multi-drug susceptible with the exception <strong>of</strong> Ampicillin; however reports <strong>of</strong> resistance<br />

have been documented; including that against Carbepenems by a carbapenase gene (bla (KPC-2 and -3)<br />

that were noted in plasmacidic and chromosomal locations. Additionally there have been reports <strong>of</strong><br />

Beta lactamase resistance.<br />

Although the organism was readily identified and treated appropriately even before final-culture<br />

returned it still proved fatal. R. Planticola is an uncommon but nonetheless important pathogen when<br />

considering antibiotic care and treatment <strong>of</strong> atypical pathogens in peritonitis.<br />

Lambert Eaton: An Elusive Diagnosis<br />

Julie Silverman, MD, Associate; Susan Merel, MD<br />

INTRODUCTION:Lambert Eaton myasthenic syndrome (LEMS) is an uncommon disorder <strong>of</strong> the<br />

neuromuscular junction. Although the symptoms are well-described, the diagnosis <strong>of</strong> LEMS can be<br />

difficult due to the non-specificity <strong>of</strong> symptoms and to the rarity <strong>of</strong> the disease. Because <strong>of</strong> its high<br />

association with malignancy, LEMS is important to consider in older patients presenting with weakness<br />

and autonomic dysfunction.<br />

CASE PRESENTATION: A 70-year-old previously healthy woman presented to her primary care<br />

physician (PCP) with concerns <strong>of</strong> dyspnea, orthopnea and peripheral edema. Review <strong>of</strong> systems further<br />

revealed malaise, fatigue, muscle weakness, nausea and excessive thirst. Patient underwent extensive<br />

cardiopulmonary workup including unremarkable ECG, TTE, myocardial scintigraphy study, chest CT scan<br />

and pulmonary function tests. Patient's symptoms continued, with worsening dry mouth, anorexia and<br />

unintentional fifteen-pound weight loss over the next two months. An EGD, colonoscopy, abdominal<br />

ultrasound and abdominal CT scan were obtained, all <strong>of</strong> which were unrevealing. Concerned that<br />

depression might be the cause <strong>of</strong> the patient's symptoms, patient's PCP started her on a selective<br />

serotonin reuptake inhibitor (SSRI). Patient denied improvement in symptoms with SSRI. Patient was<br />

ultimately admitted to the University <strong>of</strong> Washington with severe hyponatremia (Na 112 mEq/L), due to<br />

hypovolemia and SSRI-induced SIADH. Despite normalization <strong>of</strong> sodium, patient’s symptoms <strong>of</strong><br />

weakness, malaise and autonomic dysfunction continued, prompting further investigation. An<br />

electromyogram (EMG) with repetitive stimulation was performed, which showed a disorder <strong>of</strong><br />

presynaptic neurotransmission consistent with LEMS. Patient underwent extensive malignancy workup<br />

– including CT chest, abdomen, pelvis, PET scan and serum tumor markers – which returned negative.<br />

She was started on pyridostigmine and 3,4-DAP with subjective improvement in symptoms within days<br />

<strong>of</strong> starting treatment. At time <strong>of</strong> diagnosis, which was six months after initial presentation to PCP,<br />

patient had been hospitalized at five different institutions, undergone more than a dozen studies and<br />

procedures and had been evaluated by at least six different subspecialty services.<br />

DISCUSSION: This case illustrates the potential difficulty <strong>of</strong> diagnosing LEMS. While the prevalence is<br />

low, recognition <strong>of</strong> this syndrome is critical, as sixty percent <strong>of</strong> patients with LEMS have an underlying<br />

malignancy, and treatment can be quite effective in reducing symptoms.<br />

Pernicious Anemia Mimicking Acute Erythroblastic Leukemia<br />

Sarah Buckley, MD; Pamela Becker, MD<br />

INTRODUCTION: Vitamin B12 deficiency causes characteristic hematologic alterations such as<br />

increased MCV, hypersegmented neutrophils, hemolysis, and cytopenias. These resolve with<br />

replacement <strong>of</strong> vitamin B12. The following case describes a patient with pernicious anemia whose<br />

vitamin B12 deficiency was so severe that he developed hematologic abnormalities initially concerning<br />

for acute erythroblastic leukemia or myelodysplastic syndrome. These abnormalities, including the<br />

presence <strong>of</strong> peripheral blasts and severe marrow dyserethropoeisis, corrected with vitamin B12<br />

administration.<br />

CASE PRESENTATION: A 26-year-old previously healthy African <strong>American</strong> man presented to the<br />

hospital with a one-month history <strong>of</strong> fatigue and a witnessed syncopal episode. On presentation, the<br />

patient was alert with normal vital signs. A non-contrast head CT ruled out any acute intracranial<br />

process. Laboratory studies revealed a white blood cell count <strong>of</strong> 2400 cells/mm2 with a lymphocytic<br />

predominance, a hemoglobin <strong>of</strong> 5.6 g/dl with an MCV <strong>of</strong> 107 fl and a reticulocyte index <strong>of</strong> 0.2%, a<br />

bath Salts Are Dope Not Soap<br />

Authors: Lataifeh,A.MD Alourani,M. MD Zeid, F. MD,FCCP<br />

INTRODUCTION: In the time period between January to September <strong>of</strong> 2011, about 239 cases <strong>of</strong> bath<br />

salt intoxication were reported to the poisoning center <strong>of</strong> West Virginia. This drug has been nicknamed<br />

bath salts, but you don't actually use them in your bathtub. In fact, they're a type <strong>of</strong> designer drug used<br />

to get high. The main active components are mephedrone and methylenedioxypyrovalerone (MDPV).<br />

Pharmacologically, they function as a dopamine-norepinephrine reuptake inhibitor (NDRI) with<br />

stimulatory effects on the central nervous system and cardiovascular system. Clinical manifestations<br />

include adrenergic crises, hallucinations, seizures, rhabdomyolysis, nephrotoxicity and hepatotoxicity.<br />

This case series will present three patients that were admitted to the ICU after bath salts intoxication.<br />

CASE PRESENTATION:<br />

Case # 1:<br />

43 year-old male, admitted with decreased level <strong>of</strong> consciousness which required mechanical<br />

ventilation. On admission he had hypertension with tachycardia. Blood pressures (BP) as high as<br />

190/110 were recorded. His laboratory work showed hypoglycemia, acute renal failure, disseminated<br />

intravascular coagulopathy (DIC), rhabdomyolysis, lactic acidosis and hepatic injury. He was supported<br />

with intravenous fluids, benzodiazepines, bicarbonate, fresh frozen plasma, and platelet transfusions.<br />

He also needed hemodialysis and was discharged home after 12 days.<br />

Case # 2<br />

50 year-old male, brought to the emergency department (ED) with altered mental status after injecting<br />

himself bath salts intravenously. He reported that he had been using it for 2 days “at low doses.” His BP<br />

was normal on admission but on the second day it rose to 170/110. His work-up showed acute nonoliguric<br />

renal failure and mild elevation <strong>of</strong> his creatine kinase (CK). His liver enzymes were normal and he<br />

was discharged home after 3 days with normal kidney function tests and CK levels.<br />

Case # 3<br />

30 year-old male, admitted with decreased level <strong>of</strong> consciousness and aspiration. His 20 -day<br />

hospitalization in the ICU was complicated by lactic acidosis, rhabdomyolysis, hypertension, oliguric<br />

renal failure, and hepatotoxicity. He was supported with mechanical ventilation, sedation, fluids,<br />

bicarbonate, and hemodialysis.<br />

DISCUSSION: Patients presenting to the ED with adrenergic crises, altered mentation, rhabdomyolysis,<br />

lactic acidosis, hepatotoxicity or nephrotoxicity should be evaluated carefully for possible bath salts<br />

intoxication, even if the routine urine drug screens were negative. This case series represented how<br />

variable the severity and duration <strong>of</strong> bath salts intoxication syndrome can be. Of note, the DIC and<br />

hypoglycemia in the first case were unusual manifestations that have not been reported in prior case<br />

reports. The redeeming news is that as <strong>of</strong> October 21, 2011, the drug enforcement authority (DEA)<br />

announced “MDPV, its salts, isomers and salts <strong>of</strong> isomers have been temporarily controlled in schedule I<br />

<strong>of</strong> the controlled substances act.”<br />

has a half-life ranging from weeks to months. While the management <strong>of</strong> superwarfarin ingestions<br />

mirrors that <strong>of</strong> warfarin associated bleeding (high dose Vitamin K with clotting factors as clinically<br />

indicated), this remarkable case highlights that the doses <strong>of</strong> Vitamin K required can greatly exceed what<br />

most internists might consider “high dose”.<br />

CASE PRESENTATION: An eighteen year-old Caucasian female with a history <strong>of</strong> previous suicide<br />

attempts presented with abdominal distension, left flank pain and bruising <strong>of</strong> 4 days<br />

duration. Abdominal imaging revealed hemoperitonium and a left adnexal mass. Serum Beta HCG was<br />

positive. Admission lab investigations revealed an APTT <strong>of</strong> 106. The PT/INR report indicated “no<br />

coagulation observed in reaction tube”. The patient received Vitamin K and Fresh Frozen Plasma (FFP)<br />

and her INR briefly corrected to 1.6. Later on the day <strong>of</strong> admission, the patient admitted to having<br />

consumed brodifacoum every day for almost three weeks. Three days prior to admission she stated she<br />

consumed approximately 20 bars.<br />

On the morning <strong>of</strong> the 3 rd ICU day, her PT/INR was 14.8/1.4, having received 40 mg <strong>of</strong> Vitamin K, 16<br />

units <strong>of</strong> FFP and 3 doses <strong>of</strong> Prothrombin Complex Concentrate (PCC) since admission. Over the course<br />

<strong>of</strong> that day and evening her INR started to climb again despite now receiving 10 mg <strong>of</strong> Vitamin K IV every<br />

6 hours and 2 additional doses <strong>of</strong> PCC. Her PT/INR peaked at >120/ > 11 the next morning, day 7 post<br />

consumption. The patient was given a 20 mg bolus <strong>of</strong> Vitamin K IV and started on a continuous infusion<br />

at 10 mg per hour. Her next INR 3 hours into the continuous infusion was 1.46. The INR stayed below<br />

1.3 while on the continuous infusion. The infusion was stopped after 24 hours and the patient was<br />

started on 20 mg <strong>of</strong> Vitamin K PO every 4 hours. Even after 510 mg <strong>of</strong> vitamin K over 5 days, her INR<br />

climbed from 1.09 to 2.55 over the next 4 days.<br />

DISCUSSION: Super-warfarin poisonings may present therapeutic challenges far greater than seen with<br />

warfarin associated bleeding. This case illustrates that high dose Vitamin K remains the cornerstone <strong>of</strong><br />

managing super-warfarin ingestions. Most importantly, it illustrates that what most internists might<br />

consider high doses <strong>of</strong> Vitamin K may not come close to being adequate in the setting <strong>of</strong> a significant<br />

ingestion. The clinical time-line (time to peak effect, required duration <strong>of</strong> therapy) is also very different<br />

with this ingestion.<br />

Chapter Winning Abstract Curse <strong>of</strong> the Caribbean<br />

Deepa R. Ovian, MBBS William A. Agger, MD<br />

INTRODUCTION:Mycotic aneurysm is a rare but serious complication <strong>of</strong> non-typhoidal salmonella<br />

bacteremia, occuring most commonly in the abdominal aorta. The clinical presentation is nonspecific<br />

and a high index <strong>of</strong> suspicion is necessary to make an early diagnosis as mortality is high without<br />

timely intervention.<br />

CASE PRESENTATION: A 74 year old lady with rheumatoid arthritis treated with hydroxychloroquine,<br />

developed 1 episode <strong>of</strong> mild gastroenteritis <strong>of</strong> 1 -2 days duration while on a week long vacation in the<br />

Caribbean.<br />

6 weeks later, she was admitted to a local hospital with gradual worsening <strong>of</strong> her chronic back pain,<br />

generalized weakness, frequent falls and episodes <strong>of</strong> confusion. She was afebrile with stable vitals and<br />

had marked back pain with movement. Palpation tenderness was present in the paraspinal region <strong>of</strong> her<br />

lower back. CT head and x-ray <strong>of</strong> lumbar spine was unrevealing. Blood cultures grew Salmonella<br />

serotype enteritidis. The patient received IV lev<strong>of</strong>loxacin for 5 days and with clinical improvement, she<br />

was discharged with an additional 5 days <strong>of</strong> oral lev<strong>of</strong>loxacin.<br />

3 weeks later, the patient was readmitted to the same hospital with complaints <strong>of</strong> persisting back pain,<br />

weakness and confusion. She had a fever <strong>of</strong> 104.2F with midline lumbar tenderness. After transfer to<br />

our hospital for further care, we performed an MRI <strong>of</strong> the spine which showed L4- L5 diskitis. Blood<br />

cultures and disc space aspirate cultures grew S. enteritidis. As recommended by our ID consultant, we<br />

also investigated for an endovascular infection with a CT abdomen, which showed a 2 cm saccular<br />

mycotic aneurysm <strong>of</strong> the distal abdominal aorta. While on ceftriaxone, patient underwent<br />

aneurysmectomy with aortic reconstruction using autologous spiral saphenous vein graft. Tissue culture<br />

from the resected aneurysm also grew S. enteritidis. She was continued on ceftriaxone for a total <strong>of</strong> 6<br />

weeks. Her pain improved and she was doing well when seen 2 months later at follow-up in clinic .<br />

DISCUSSION: This case demonstrates the importance <strong>of</strong> clinicians' awareness that adults with a relapse<br />

<strong>of</strong> non- typhoidal salmonella sepsis <strong>of</strong>ten have a serious endovascular infection. This risk is increased in<br />

patients above 50 years <strong>of</strong> age with atherosclerosis. In such patients, it is important to look for a<br />

vascular infection even if a focus <strong>of</strong> infection has been identified elsewhere. Anti-salmonella<br />

antimicrobial therapy should be started and a CT or MRI with contrast should be performed on an<br />

emergency basis. Following diagnosis, surgical resection <strong>of</strong> the aneurysm with in situ graft<br />

revascularization, the procedure <strong>of</strong> choice, should be done as soon as possible. Postoperative<br />

antimicrobial therapy for 6-8 weeks based on ESR and clinical response is recommended.<br />

Renal ischemic preconditioning: that which does not kill us makes us stronger<br />

Asma Arayan, MD; Second Author: Balaji Srinivasan, MD<br />

INTRODUCTION: In the setting <strong>of</strong> ischemic injury to an organ, it might be expected that the organ<br />

would be more susceptible to a second ischemic insult. Considerable data however exists, that there are<br />

intrinsic mechanisms that actually protect the organ against subsequent ischemia. This concept referred<br />

to as ischemic preconditioning is an innate tissue adaptation induced by ischemia or toxic insult that<br />

confers organ protection against subsequent exposure to the same or other injury.<br />

CASE PRESENTATION: We recently had two patients with acute kidney injury who were exposed to a<br />

second nephrotoxic insult. They did not have a significant increase in their serum creatinine or decrease<br />

in urine output after the second insult. The first patient was a 55-year old woman with history <strong>of</strong><br />

diabetes with microalbuminuria. She presented with AKI likely due to acute tubular necrosis from<br />

volume depletion following a diarrheal illness. As she had multiple risk factors for contrast nephropathy<br />

including diabetes, elevated serum creatinine and volume depletion, the plan was to do a computed<br />

tomography (CT) <strong>of</strong> the abdomen without intravenous iodinated contrast. However, intravenous<br />

contrast was inadvertently administered. Although she was exposed to a second nephrotoxic insult, she<br />

did not develop contrast nephropathy. Her urine output improved overnight and her creatinine was<br />

back to normal over the next few days. The second patient was a 73-year old male admitted with AKI<br />

due to rhabdomyolysis. He required one hemodialysis treatment. Over the next 3-4 days his creatinine<br />

returned to baseline. By hospital day 6, he developed worsening hypoxemia and he was suspected to<br />

have pulmonary embolism. He was given IV iodinated contrast for a chest CT. He had good urine output<br />

and his serum creatinine was stable over the next few days. Despite being exposed to a second<br />

nephrotoxic insult within a week, he did not develop contrast nephropathy.<br />

DISCUSSION: Ischemic preconditioning was first described in the heart. Episodes <strong>of</strong> ischemia in canine<br />

myocardium, followed by reperfusion protected against myocardial necrosis during a subsequent<br />

prolonged period <strong>of</strong> ischemia. Patients with pre-infarction angina have smaller infarct size when<br />

compared to patients with acute myocardial infarction without preceding angina. Animal studies have<br />

shown that a similar phenomenon occurs in the kidneys. Renal tubular epithelium in these studies has<br />

been shown to be resistant to a second nephrotoxic insult after initial injury. Ischemic preconditioning<br />

can be local or remote. Human studies have shown that remote ischemic preconditioning prevents<br />

acute kidney injury in patients undergoing cardiopulmonary bypass-assisted cardiac surgery.<br />

Biochemical pathways involved in ischemic preconditioning have recently been elucidated. Our cases<br />

suggest that local renal ischemic preconditioning could occur in humans.<br />

A Non-Compact Diagnosis<br />

Tessa W Damm, DO Second Author: Kurt Pfeifer, MD, FACP<br />

INTRODUCTION: Left ventricular non-compaction is a rare cause <strong>of</strong> congenital cardiomyopathy worthy<br />

<strong>of</strong> proper diagnosis as these patients are at increased risk <strong>of</strong> arrhythmic events as well as<br />

thromobembolic complications.<br />

CASE PRESENTATION: A 30-year-old gentleman presented with a four-week history <strong>of</strong> non-productive<br />

cough and dyspnea on exertion. His past medical history was unremarkable except for a seven pack-year<br />

smoking history. Twice previously he had been evaluated for the same symptoms and received<br />

antibiotics and short-acting bronchodilator therapy for treatment <strong>of</strong> an upper respiratory tract infection.<br />

With these therapies he had only transient relief <strong>of</strong> his symptoms. On his third presentation, physical<br />

examination revealed an S3 cardiac gallop and a laterally displaced point <strong>of</strong> maximal<br />

impulse. Concurrent chest radiograph was notable for cardiomegaly and evidence <strong>of</strong> cardiopulmonary<br />

vascular congestion. Chest CT was unremarkable for pulmonary embolus. Echocardiography revealed<br />

globally decreased left ventricular systolic function with an estimated ejection fraction <strong>of</strong> 10–20%. The<br />

echocardiogram was also notable for a thickened appearance to the left ventricular wall. This finding<br />

prompted further evaluation with cardiac MRI which revealed a ratio <strong>of</strong> trabeculated to compacted<br />

myocardium on the lateral wall <strong>of</strong> the left ventricle <strong>of</strong> greater than 2:1, confirming cardiomyopathy <strong>of</strong><br />

non-compaction etiology. The patient was started on optimal medical management for heart failure<br />

including a beta-blocker, angiotensin converting enzyme inhibitor, and spironolactone. He was also<br />

started on anticoagulation as the risk <strong>of</strong> thromboembolic complications in patients with non-compaction<br />

cardiomyopathy is increased. Repeat echocardiogram approximately three months after initiation <strong>of</strong><br />

optimal medical management did not reveal improvement in left ventricular systolic function; therefore,<br />

the patient is currently undergoing evaluation for placement <strong>of</strong> an automatic implantable cardioverterdefibrillator<br />

as well potential future heart transplantation.<br />

DISCUSSION: Non-compaction cardiomyopathy is an uncommon etiology <strong>of</strong> heart failure with an<br />

estimated prevalence <strong>of</strong> 0.05-0.24%. Age <strong>of</strong> initial presentation varies widely and males are more<br />

commonly affected than females. It is believed that the disorder is secondary to an arrest <strong>of</strong> normal<br />

compaction <strong>of</strong> a loose meshwork <strong>of</strong> trabeculae which constitute the myocardium between the fifth and<br />

eighth week <strong>of</strong> embryonic development. In addition to systolic dysfunction, this population <strong>of</strong><br />

individuals is at unique risk for arrhythmias and thromboemolic events. Aggressive medical management<br />

with heart failure pharmacotherapy and defibrillator placement is the mainstay <strong>of</strong> treatment. If these<br />

measures fail, many patients with non-compaction cardiomyopathy are candidates for heart<br />

transplantation given their relative young age and lack <strong>of</strong> comorbid conditions. Furthermore, first<br />

degree relatives <strong>of</strong> these patients should be considered for clinical screening due to the disease’s<br />

identifiable genetic associations.<br />

Syphilis-related immune reconstitution inflamatory syndrome<br />

Zouyan Lu, MD Second Author: J. Njeri Wainaina, MD<br />

INTRODUCTION: Morbidly and mortality associated with human immunodeficiency virus (HIV)<br />

infection has improved greatly with the advent <strong>of</strong> highly active antiretroviral therapy<br />

(HAART). However, rapid restoration <strong>of</strong> the host immune system may sometimes lead to a pathologic<br />

host immune response.<br />

CASE PRESENTATION: A 45 year-old male with AIDS presented with acute onset aphasia approsimately<br />

one year after self-discontinuing his HAART. CT <strong>of</strong> the head showed acute ischemic stroke and cerebral<br />

vascular pathology. Cerebrospinal fluid (CSF) analysis was consistent with meningitis; serum free<br />

treponemal antibody was reactive. He was treated for meningovascular syphilis with 2 weeks <strong>of</strong><br />

intravenous penicillin and restarted on his previous HAART <strong>of</strong> efavirenz and lamivudine/zidovudine. He<br />

returned a day after completing treatment with complaints <strong>of</strong> fever, neck pain and acute onset<br />

headache. CT scan showed intraventricular hemorrhage, new right parietal infarcts and findings<br />

consistent with vasculitis. He was started on empiric treatment with IV vancomycin, ceftriaxone, and<br />

acyclovir. Within 24 hours <strong>of</strong> admission, he had acute neurological decline, repeat imaging showed new<br />

infarcts. CSF was significant for elevated red blood cell count, a low glucose and neutrophilic<br />

pleocytosis. Gram stain and culture were negative. CSF cryptococcal antigen, HSV PCR, and VDRL were<br />

also negative. His HIV viral load, when compared to values obtained 3 weeks prior, showed a 3 log<br />

decrease. Brain MRI showing more new infarcts and leptominingeal enhancement, in conjunction with<br />

the rapid decline in viral load, led to concern for IRIS. Empiric antibiotics were stopped and high-dose<br />

steroids were started with initial response. But the patient later developed step-wise decline in<br />

neurologic status steroids were tapered down. The patient eventually became minimally responsive<br />

with extensor posturing. After discussion with his family, he was transferred to home hospice.<br />

DISCUSSION: IRIS <strong>of</strong>ten presents with a paradoxical decline caused by a pathologic response <strong>of</strong> the<br />

host’s reconstituted immune system after initiation <strong>of</strong> HAART. Some investigators have reported an<br />

incidence as high as 23% in patients starting HAART. The risk for developing IRIS appears to be directly<br />

proportional to opportunistic infection disease burden. IRIS should be suspected when patients present<br />

with unusual symptoms or disease course with a temporal relation to immunological recovery following<br />

initiation <strong>of</strong> HAART. It is most commonly described in association with mycobacterial, fungal, and viral<br />

infections. While, any organ system can be involved, reports <strong>of</strong> CNS IRIS are less common. There are no<br />

published trials for the treatment <strong>of</strong> IRIS, but case studies suggest appropriate treatment <strong>of</strong> the<br />

underlying opportunistic infection with or without the addition <strong>of</strong> corticosteroids. Our patient had<br />

progression <strong>of</strong> CNS vasculitis associated with a rapid and robust immune recovery following initiation <strong>of</strong><br />

HAART. The only opportunistic infection identified was meningovascular syphilis for which he had been<br />

appropriately treated. He demonstrated clinical neurological improvement with initiation <strong>of</strong> steroids<br />

and catastrophic decline when tapering was attempted.<br />

An Incidental Aortic Ulcer:Hickam's dictum Vs Occam's razor<br />

Christiane Mbianda,Jennifer Yacub,Peter-Trung Phan, Siddharta Singh,Medical <strong>College</strong> <strong>of</strong><br />

Wisconsin,Milwaukee,WI<br />

INTRODUCTION: A 73-year- old male was hospitalized for evaluation <strong>of</strong> a four-week history <strong>of</strong> diarrhea.<br />

Initial evaluation revealed leukocytosis (WBC = 16,000/µl); elevated inflammatory markers (ESR =<br />

88mm/Hr). Abdominal CT showed colonic thickening around the hepatic flexure. A colonoscopy revealed<br />

an ulcerating, necrotic mass in the cecum, confirmed to be an adenocarcinoma on pathological exam.<br />

The patient had an episode <strong>of</strong> atrial flutter and underwent a contrast enhanced chest CT for suspected<br />

pulmonary embolism (PE). Chest CT showed no PE but incidentally revealed an aortic ulcer in the distal<br />

aortic arch. A PET scan showed no metastatic disease, but marked uptake in the region <strong>of</strong> the aortic<br />

ulcer, suggesting inflammation. A literature search revealed an association between infectious aortitis<br />

and colon cancer but blood cultures drawn on admission remained negative, and the patient remained<br />

afebrile. Subsequently, he was noted to have a hoarse voice, which prompted repeat imaging that<br />

revealed marked progression <strong>of</strong> the aortic ulcer and a 3.3 cm pseudo aneurysm. The patient underwent<br />

emergent surgery and the resected necrotic aortic arch grew Clostridium septicum. He initially made a<br />

remarkable recovery, but 3 days prior to the planned resection <strong>of</strong> his colon cancer - he suffered a<br />

cardiac arrest and died.<br />

DISCUSSION: This case is notable for two reasons. Firstly, Clostridium septicum is an uncommon cause<br />

<strong>of</strong> aortitis and has a striking association with colon cancer. To the best <strong>of</strong> our knowledge, we are<br />

reporting the 27 th case <strong>of</strong> C. septicum aortitis and the 21 st case associated with colon cancer.<br />

Secondly, the diagnostic journey in our case is intriguing. The incidental discovery <strong>of</strong> an aortic ulcer in a<br />

patient with newly diagnosed colon cancer set into play an age old conflict between Occam’s razor and<br />

Hickam’s dictum. Occam’s razor, which states “plurality must not be posited without necessity” is the<br />

classic heuristic <strong>of</strong> medical diagnosticians but with our aging patient population suffering an epidemic <strong>of</strong><br />

chronic diseases, Hickam’s dictum, which states - “a patient can have as many diagnoses as he darn well<br />

pleases” is holding true more <strong>of</strong>ten. In our case, as blood cultures were negative and the patient<br />

remained afebrile, Hickam’s dictum dominated initially–prompting the hypothesis <strong>of</strong> an atherosclerotic<br />

aortic ulcer and an unrelated diagnosis <strong>of</strong> colon cancer. This changed with the development <strong>of</strong><br />

hoarseness–which signaled the progression <strong>of</strong> the aortic arch pathology. This prompted repeat imaging,<br />

surgery and subsequent pathological exam which revealed a parsimonious explanation for the patient’s<br />

clinical conditions and the ultimate triumph <strong>of</strong> Occam’s razor: Proliferation <strong>of</strong> C. septicum in the<br />

anaerobic, necrotic areas <strong>of</strong> the colon cancer with eventual occult C. septicum bacteremia and resulting<br />

aortitis.<br />

Cellulitis As A Symptom, Not A Diagnosis<br />

Jessica L White, MD<br />

INTRODUCTION: Skin and s<strong>of</strong>t tissue infections require a broad differential diagnosis especially when<br />

presenting with frequent recurrence despite appropriate treatment. Further investigation can help<br />

diagnose other underlying disease processes that should be considered in atypical cellulitis.<br />

CASE PRESENTATION: A 64 year-old woman with a past medical history <strong>of</strong> hypertension and eczema<br />

presented with recurrent lower extremity pain and erythema. She had a history <strong>of</strong> several episodes <strong>of</strong><br />

cellulitis that improved with antibiotics but recurred shortly after completing therapy. She was treated<br />

with multiple courses <strong>of</strong> antibiotics over a period <strong>of</strong> 4 months. Physical examination during this<br />

presentation demonstrated bilateral inguinal lymphadenopathy, multiple hypopigmented skin patches<br />

and diffuse papular rash with lichenification and crusting on the torso, upper and lower extremities.<br />

Initial laboratory evaluation was significant for leukocytosis and elevated liver function tests. Chest,<br />

abdomen and pelvis CT showed diffuse bilateral lymphadenopathy as well as multiple small pulmonary<br />

nodules. Subsequent lymph node and skin biopsies confirmed a diagnosis <strong>of</strong> CD30+ peripheral T cell<br />

lymphoma not otherwise specified (PTCL NOS). She underwent 6 cycles <strong>of</strong> cyclophosphamide,<br />

hydroxydaunorubicin, vincristine and prednisone (CHOP), and 3 cycles <strong>of</strong> etoposide,<br />

methylprednisolone, cytarabine and carboplatin (modified ESHAP). Despite these therapies, she had<br />

recurrence <strong>of</strong> her lymphoma and died 9 months after diagnosis.<br />

DISCUSSION: Peripheral T-cell lymphomas account for approximately 12 percent <strong>of</strong> all adult non-<br />

Hodgkin lymphomas with PTCL NOS being the most common subset at 30 percent. Approximately half<br />

the cases <strong>of</strong> PTCL NOS include extranodal involvement, and cutaneous findings are a common<br />

presentation. Our patient presented with recurrent cellulitis <strong>of</strong> her lower extremities which did not<br />

adequately respond to appropriate antibiotic therapy. Our review <strong>of</strong> the literature found only two<br />

abstracts citing similar cases <strong>of</strong> PTCL presenting as recurrent cellulitis. Diagnosis requires tissue biopsy<br />

<strong>of</strong> either involved skin or lymph nodes. Treatment <strong>of</strong> PTCL NOS involves combination chemotherapy<br />

with CHOP being the most commonly used therapy. This neoplasm has a poor prognosis due to an<br />

aggressive course with high chance <strong>of</strong> relapse, and survival is associated with disease stage at the time<br />

<strong>of</strong> diagnosis. One study cited 82 PTCL NOS patients with cutaneous findings had an overall unfavorable<br />

prognosis with a 20% five-year survival. Maintaining a high index <strong>of</strong> clinical suspicion in a patient with<br />

atypical skin findings such as recurrent infection can help lead to earlier diagnosis and treatment.<br />
