Schistosomiasis and malignancy.

It is generally accepted that schistosomiasis, if not causative, is at least associated with malignancy. In this review, the epidemiology of schistosomiasis and bladder carcinoma, as well as the role of chronic bladder infection, are discussed together with known carcinogenic factors, possible abnormal vitamin metabolism and/or deficiencies and factors that influence conjugated carcinogens. Experimental evidence is briefly examined and recent work from the Far East on schistosomiasis and colon carcinoma reviewed.

Ubombo and the site of David Bruce's discovery of Trypanosoma brucei.

The site and remains believed to be those of the camp where Sir David Bruce and his wife Mary worked between 1894 and 1897, and where Bruce discovered the causative agent of nagana and its transmission by the tsetse fly, have recently been discovered at the small village of Ubombo in northern KwaZulu (Zululand), South Africa. The site where these remnants were found fits the meagre, albeit significant, information presented by Bruce in his writings on the location of the camp.

The microbial aetiology of summer paediatric gastroenteritis at Ga-Rankuwa Hospital in South Africa.

Stool material from seventy-eight children below the age of three years was examined for the presence of various enteropathogens. The patients had been admitted to the Ga-Rankuwa hospital for rehydration therapy. A causative agent was identified in 76.

Unusual presentations of cerebral hydatid disease in children.

Three children with hydatid disease of the central nervous system (CNS) were seen. In two patients the lateral ventricles were involved, whilst one case involved the cerebellar hemisphere. In addition, one child presented with a deposit in the maxillary antrum, and deposits were also found in the liver.
