The Mianmin are a mobile population occupying a remote lower montane area at 100-1200 m altitude in the north-western interior of Papua New Guinea (PNG). Major medical problems include malaria and bancroftian filariasis. An entomological survey conducted along an altitudinal transect from 170 to 1000m identified Anopheles koliensis as the predominant malaria vector below 650 m, with A. punctulatus...
The efficacy of a 6 months course of twice weekly therapy with 4 drugs for tuberculosis, preceded by a 2-3 weeks intensive daily phase, is unknown. Implementation of this regime as community-based directly observed therapy in Africa is highly effective (85% completion rate); it is important to estimate the efficacy of the regime before advocating its widespread use and before conducting prospective...
Envenoming by a number of species of snake may affect the myocardium or cause electrocardiographic changes; several different mechanisms have been proposed. In a prospective study of snake bite in Papua New Guinea, electrocardiographic changes were observed in 36 of 69 patients (52%) envenomed by the taipan (Oxyuranus scutellatus), 2 of 6 (33%) envenomed by death adders (Acanthophis sp.) and one envenomed...
We examined epidemiological aspects of Ascaris-induced intestinal obstruction (AI-IO) through analysis of published reports on the subject. In 9 studies of >=100 patients admitted to hospital due to ascariasis, intestinal obstruction was the single most common complication and accounted for 38-87.5% of all complications (weighted mean 72%). The proportion of intestinal obstruction caused by ascariasis...
