[Extrapulmonary tuberculosis: retrospective study of 107 cases]

We studied retrospectively 107 cases of extrapulmonary tuberculosis diagnosed during a period lasting from 1988 to 1992 in a General Hospital (asistencial area of 185,000 population). These cases represent 35.7% from the overall tuberculosis diagnosed in the same period of time and same attendance centre, with an mean rate of 11.5 cases/100,000 population. 62.6% were males and 37.4% were females. Mean age was 40.7 +/- 22 years old (range 2-84). The most frequently age group was 20-30 years old and 56% were persons less than 50 years of age. Smoking and alcohol (53.6% and 36.5% respectively) were the greatest factors risk; only two persons had been infected by the HIV. The most common forms of disease were tuberculosis pleural effusions (29%), genito-urinary (22%) and lymph node disease (20.5%). The diagnosis was performed by consistent pathological findings in 64% and in 53% microbiologic procedures were found positives. 74% patients received treatment by recommended 9-month regimen (three drugs) and 24% 6-month regimen (four drugs) with the same efficacy. Relevant adverse reactions were not found except a case of neurotoxicity.
