In this study (Table 20), there were significant association between
smoking and some symptoms either in smear +ve or in smear -ve cases for
AFB. In smear +ve cases smokers statistical significant difference was
found than non smokers, as regard expectoration, dyspnea, weight loss, and
chest wheezes, and in cases of smear -ve for APB significant higher
association was present in cough, expectoration and chest wheezes than
smear -ve non smokers. Other symptoms showed non significant
differences. It was reported by Alcaid et al. (1996) that, smokers routinely
present with respiratory symptoms, simulating that produced by TB,
namely prolonged cough, expectoration, dyspnea, anorexia and weight loss.
So this explains why dyspnea, weight loss and expectation were
significantly associated with smoking in tuberculous patients.
Table (2 J) elucidates the mean duration ofrespiratory symptoms,
mean duration of haemoptysis showed statistically significant difference
between smear +ve and smear -ve cases for APB. The lowest mean
duration was for haemoptysis (1.3 month) followed by chest pain (2.32
month) in smear +ve cases and the highest was for chest wheezes.
(l3.97month) followed by dyspnea (6.35 month) and cough represented(
3.6 month) and expectation (3.9 month). Similar results were obtained by
Madebo and Lindtjorn (1999) found mean duration for each symptoms.
Cough (5.7 month), expectoration (3.8 month) haemoptysis (1.6 month),
chest pain (4.3 month) and dyspnea (2.5 month). Other authors most of
them worked on the mean duration of symptoms in toto as Niijima et al.
(1990) in Japan, mean duration was (3.5 month) and Pirkis et al (1996)
from Australia mean duration of symptoms 72.9± 84.9 day, and also
Wandwalo and Morkve (2000) found mean duration of symptoms was
185 day.
