Miliary tuberculosis infection in childhood remains a significant health problem in developing countries. To characterize the clinical features of the disease, symptoms, signs and laboratory findings, associated infections and outcomes of the 23 children (14M, 9F) with miliary tuberculosis admitted to the Dicle University Hospital, Diyarbakir, Turkey from 1990 to 1997 were analysed. Mean age of the patients was 3.7 y ranging between 6 months and 11 y. All but 3 patients were below 6 y of age, and 5 of the patients were under 1 y of age. All of the children had not received BCG vaccination except for 1 who was immunized after the age of 5 y. Only 6 children had a positive reaction to 5 TU tuberculin test at admission to hospital. Eight of the 23 subjects were infected in the family, and all were nonHIV infected cases. All of the children were diagnosed clinically and by a miliary infiltrate visible on chest roentgenogram. Five cases had positive culture results for Mycobacterium tuberculosis. Duration of onset of symptoms prior to admission ranged between 15 d and 8 months with a mean of 58 d. The most frequently seen symptoms and clinical findings were fever in 17 cases, rales in 14, loss of appetite and weight in 10 and hepatosplenomegaly in 9 cases. Two cases had prior measles infection and 1 of the patients presented facial paralysis. Seven cases had also tuberculous meningitis. The outcome in general was good, with mortality in 2 cases.
