From January 1982 to April 1987 , 1500 cases of fiberoptic bronchoscopy (FOB) were performed. Among these cases, 37 were suspected of having pulmonary tuberculosis but their sputum examination was either negative or they were not able to expectorate. In all these cases pulmonary TB was confirmed either by bronchoalveolar lavage (BAL) fluid examination or by biopsy. We conclude that FOB is ...

INTRODUCTION Pulmonary tuberculosis (TB) requires an early diagnosis for prompt introduction of treatment and prevention of transmission. Definitive diagnosis is obtained by microbiological culture and identification of Mycobacterium tuberculosis in respiratory specimens, mostly sputum samples. MATERIALS AND METHODS Retrospective data analysis of all patients suspected of pulmonary TB that su...

Background: Besides charging the patients with outstanding costs, tuberculosis (TB) causes high mortality and morbidity in a country. We studied the sensitivity, specificity, positive and negative predictive values as well as the efficiency of buffy coat smear test in patients who were pulmonary TB suspects. This research was conducted at Massih Daneshvari Hospital, National Research Institute ...

BACKGROUND The diagnosis of active pulmonary tuberculosis (TB) remains a challenge in clinic, especially for sputum negative pulmonary TB. Bronchoalveolar lavage fluid (BALF) has higher sensitivity than sputum for detection of Mycobacterium tuberculosis (Mtb). However, bronchoscopy is invasive and costly, and not suitable for all patients. In order to make TB patients get more benefit from BALF...

Direct smear microscopy of sputum forms the mainstay of TB diagnosis in resource-limited settings. Stained sputum smear slides can serve as a ready-made resource to transport sputum for molecular drug susceptibility testing. However, bio-safety is a major concern during transport of sputum/stained slides and for laboratory workers engaged in processing Mycobacterium tuberculosis infected sputum...

Investigations into the bacteriology of chronic bronchitis (May, 1953a and b) have shown that purulent sputum usually contains one or more pathogens and that such a sputum can be rendered mucoid, at any rate temporarily, when the patient is treated with the appropriate antibiotic. Subsequent studies (May, 1954) included patients diagnosed clinically as infected asthma, and the macroscopical app...

Background: the national and international guidelines of the WHO and the IUALTD recommend priority sputum smears for diagnosis of pulmonary tuberculosis. We studied the use and diagnostic yield of sputum, broncho-alveolar and gastric lavage (BAL, GL) in the reference national mycobacteria Laboratory (NRL) (Burkina Faso) to see if clinicians follow the recommendations in the prescription of spec...
