A retrospective study of 24 pheochromocytomas observed between 1974 and 1987 is reported. Hypertension is the most frequent sign. In 19 cases diagnosis of pheochromocytoma was confirmed by surgery. In 3 cases, preoperative diagnosis was "silent" adrenal tumor. Two had exploratory surgery for renal artery stenosis and renal tumor. Diagnostic strategy and its evolution with high sensitivity biochemical examinations and computed tomography was analysed.
A case of pharyngeal stenosis in Behcet's disease is reported. A parallelism is done with other systemic disorders such as lupus erythematosus and Wegener's disease. Vasculitis and localised myositis are incriminated in the mecanism of the pharyngeal stenosis.
304 cases of glomerulonephritis were biopsied in Tunisia and studied morphologically. The incidence of glomerulonephritis with marked proliferation of endocapillary cells was 60%, a figure considerably higher than in other large series. Using a Clq binding assay, statistically significant levels of immune complexes were found in cases of acute proliferative glomerulonephritis. Amongst other types of glomerulonephritis, circulating immune complexes were frequently found in systemic lupus erythematosus but only in a low percentage of primary glomerulonephritis with or without immunoglobulin deposits.
