Onchocerciasis in members of an expedition to Cameroon: role of advice before travel and long term follow up.

Abstract

Delayed heart repolarisation is marked by prolonged QT interval on electrocardiography and may be complicated by ventricular arrhythmias, syncope, and sudden death.' Such events have recently been associated with severe malnutrition, as occurs in anorexia nervosa2 and after ileojejunal bypass.3 These reports have prompted us to measure QT interval in adult patients with coeliac disease, a condition which often presents with nutritional impairment.
