BACKGROUND Effective tuberculosis (TB) control in HIV-prevalent settings is hindered by absence of accurate, rapid TB diagnostic tests. We evaluated the accuracy of a urine lipoarabinomannan (LAM) test for TB diagnosis in South Africa. METHODS Hospitalized adults with signs and/or symptoms of active TB were enrolled. Sputum smear microscopy and mycobacterial culture, mycobacterial blood cultu...
SETTING Lilongwe District, Malawi. OBJECTIVE To assess the cost and cost-effectiveness of new treatment strategies for new pulmonary tuberculosis patients, introduced in 1997. METHODS For new smear-positive pulmonary patients, two strategies were compared: 1) the strategy used until the end of October 1997, involving 2 months of hospitalisation at the beginning of treatment, and 2) a new de...
BACKGROUND Previous studies suggest that bronchoscopy and a single induced sputum sample are equally effective for diagnosing pulmonary tuberculosis. METHODS In a prospective study of subjects with possibly active pulmonary tuberculosis, the diagnostic yield of three induced sputum tests was compared with that of bronchoscopy. Subjects either produced no sputum or (acid fast) smear negative s...
BACKGROUND The significance of the possible presence of infection on the Pap smear of asymptomatic women based on cytological criteria is practically unknown. MATERIALS AND METHODS A total of 1117 asymptomatic nonpregnant women had Pap smear tests and vaginal as well as cervical cultures completed (622 with and 495 without inflammation on the Pap smear). RESULTS Out of the 622 women with in...
The microscopic observation drug susceptibility assay (MODS) is a novel and promising test for the early diagnosis of tuberculosis (TB). We evaluated the MODS assay for the early diagnosis of TB in HIV-positive patients presenting to Pham Ngoc Thach Hospital for Tuberculosis and Lung Diseases in southern Vietnam. A total of 738 consecutive sputum samples collected from 307 HIV-positive individu...
Background and purpose: Computed tomography (CT) scan is of great help in confirming the diagnosis of tuberculosis (TB) before the sputum test result. The purpose of this study was to investigate the relationship between pulmonary involvement patterns in CT scans of TB patients with positive sputum smears. Materials and methods: This retrospective descriptive-analytical study was conducted usi...
