title: An open technique of pleural biopsy in the diagnosis of tuberculous effusions.
abstract: To assess an open technique of pleural biopsy as an aid to diagnosis in pleural disease 107 African patients with radiological evidence of pleural effusion underwent biopsy. In 87 there was radiological evidence of an effusion but not of underlying lung disease; 73 patients (84%) in this group were ultimately diagnosed as suffering from tuberculosis and of these 56 (77%) had a positive pleural biopsy. There was a heavy male predominance of tuberculous infection (male:female ratio approximately 5:1) and half of the patients were aged 21 to 30 years. In the 20 patients with radiological changes in the lung a diagnosis was established by biopsy in 13 cases. Four of these were tuberculous and a further two cases of tuberculosis were established on clinical grounds.
