Dracunculiasis: an approach to hasten worm expulsion

Twenty patients with Guinea worm disease having a total of 29 emerging worms in a rural village of North West Frontier Province, were put on a 5-day course of antibiotics and antiinflammatory drugs and compared with age-matched control patients. The ulcer sites of emerging worms were kept continuously moist, and 18 worms were extracted from 14 patients during the above mentioned period. The average time taken for the entire worm to be expelled in these patients was considerably shorter (13.6 days) than in controls (89 days). Seven (39%) of these worms were expelled spontaneously whereas the remaining 11 (61%) were pulled out manually with relative ease. Fifteen (75%) patients in this study had a single emerging worm, three (15%) had two emerging worms and two (10%) patients had four or more emerging worms.
