Fanconi Anemia: Guidelines for Diagnosis and Management
made by four small parathyroid glands located in the
neck behind the thyroid gland. Hypoparathyroidism
occurs when there is too little PTH. Blood calcium levels
fall, and phosphorus levels rise. 5
Hypopharynx: The lower part of the pharynx and the
part of the throat that connects to the esophagus.
Hypopigmentation: Diminished pigmentation in a
body part or tissue (such as the skin). 1
Hypoplastic: A condition of arrested development in
which an organ or part remains below the normal size
or in an immature state. 1
Hypospadias: A relatively common congenital defect
in which the opening of the urethra is on the underside,
rather than at the end, of the penis. Infants with hypospadias
should not be circumcised; the foreskin should
be preserved for use in later surgical repair. 5
Hypothalamus: An area of the brain that produces
chemical messages that control body temperature,
hunger, moods, release of hormones from many glands,
especially the pituitary gland. These messages also
influence sex drive, sleep, and thirst. 5
Hypothyroidism: A condition in which the thyroid
gland fails to produce enough thyroid hormone. 5
Ileus: Obstruction of the bowel; the condition is commonly
marked by a painful distended abdomen, vomiting
of dark or fecal matter, toxemia, and dehydration
that results when the intestinal contents back up
because peristalsis fails, although the lumen (the inside
space of a tubular structure, in this case the bowel) is
not occluded. 1,11
IM: Refers to giving an injection intramuscularly.
