A case of systemic Chromobacterium violaceum infection, believed to be the first reported in a Papua New Guinean, is described. Autopsy disclosed multiple liver abscesses and the diagnosis was made by recovery of the organism from one of the abscesses. Aspects of management of this uncommon infection are discussed.
Among the Melanesian population of Papua New Guinea, cancer of the oral cavity associated with betel nut chewing is the most commonly reported. Liver cancer is also common and is closely associated with chronic hepatitis-B infection. Burkitt's lymphoma occurs along coastal areas with a high rainfall and intense malaria transmission. The descriptive epidemiology of other cancers in Papua New Guinea is also discussed.
An unusual infection occuring in the East Sepik Province of Papua New Guinea is reported. The patients come from villages on the Sepik River or its tributaries. The lesions consist of cutaneous nodules and papillomas which are slowly progressive. An unidentified organism, apparently a gram positive bacillus, is seen in large numbers in the lesions; a natural habitat in soil or water or on vegetation seems likely.
