Ulcerative colitis in Bangladesh.

A total of 100 cases with chronic diarrhoea having no apparent cause were investigated. Fifty seven of these cases fulfilled the diagnostic criteria of ulcerative colitis. Fortyone of these 57 patients were treated for acute amoebic dysentery during the initial episodes of their illness. Since attack of acute amoebic dysentery is liable to produce post-dysenteric ulcerative colitis, it is possible that ulcerative colitis exist in this country in at least 2 forms, idiopathic and post-dysenteric.
