Abstract
Extrapulmonary tuberculosis (TB) remains a major health problem in Australia, with 24.3% of all new tuberculosis notifications in 1984 of extrapulmonary origin. We have reviewed our recent experience to assess the epidemiology and clinical features that may allow the earlier recognition and treatment of patients at risk for this disease. From 1980-1985, 51 cases of extrapulmonary TB were identified at Westmead Hospital. Thirty-eight patients were born outside Australia, mainly in South-East Asia and Europe. The commonest sites of disease were the lymph nodes, genitourinary tract, pleura and bone. Tuberculous lymphadenitis occurred predominantly in South-East Asians, whilst genitourinary tract disease was confined to Caucasians. A history of previous exposure to tuberculosis was obtained in 45% of patients. Fever, sweats and weight loss were noted in less than half of the cases. Changes consistent with old pulmonary disease were found on routine chest X-ray in 34% of cases. Laboratory confirmation of TB was made in 88% of cases, with typical histopathology in 90% and isolation of Mycobacterium tuberculosis in 69% of specimens submitted for analysis. Drug resistance was confined to isolates from South-East Asian patients.
