title: [Clinical, biological and radiological spectrum of newly diagnosed pulmonary tuberculosis].
abstract: The aim of the present study was to describe the clinical, biological and the chest-X ray presentations of newly diagnosed pulmonary tuberculosis. A retrospective study of 200 patients was performed from January to October 2004 in the respiratory diseases unit of Dakar's University Teaching Hospital. Among the 200 cases, 140 (70%) were male, giving a sex ratio of 2.3. The mean age of our patients was 35.5 years (range: 14-81 years). The group age of 20 to 39 years was the most affected (55,5% of patients). The median diagnostic delay was 4 months (range: 7 days to 2 years). Haemoptysis revealed the disease in 27% of cases. The chest X-ray showed bilateral lesions in 65% of cases. When they were unilateral, the right side was the most concerned. Of the 200 patients, the lesions interested all parts of at least one lung in 106 (53%). Among our patients, 153 (76.5%) had cavitations and 145 (72.5%) had infiltrates. A pleural effusion was associated to the lung lesions in 10% of the patients. Biologically, we reported 80% cases (n=160) of hypochromic microcytic anaemia. Of the 27 HIV tests done, 18 (66.7%) were positive all for HIV1. Delay in the diagnosis of pulmonary tuberculosis was very long and our data illustrate the need for improved education of the community and event of healthcare workers about the benefit of early diagnosis of tuberculosis.
