Heat treatment of Mycobacterium ulcerans infections without surgical excision.

Eight patients from Zaire with Mycobacterium ulcerans infection were treated by the local application of heat to maintain a temperature of approximately 40 degrees C in the ulcerated area. All lesions healed without surgical intervention and without local recurrences during follow-up periods of up to 22 months. This study shows that local heat promotes healing of M. ulcerans lesions. We postulate that the mechanism is primarily by direct inhibition of multiplication of M. ulcerans. Other possible contributory effects are discussed.

Microfilaruria in onchocerciasis. A clinical and epidemiological follow-up study in the Republic of Chad.

Microfilariae of O. volvulus were recovered from the urine of 11% of the residents of a village in the Republic of Chad where onchocerciasis was holoendemic. A follow-up study of the same population 3 years after the original investigation revealed that microfilaruria was still present and that living microfilariae of O. volvulus could be recovered from small urine samples obtained by high catherization of the ureters. Radiological changes consistent with chronic pyelitis were found in 4 out of 14 persons with microfilaruria who were examined by retrograde pyelography. The recovery of microfilariae in the urine was associated with the intensity of the infection, as determined by counts of microfilariae in skin snips and the number of onchocercomata. A systematic comparison for differences between onchocerciasis patients with and without microfilaruria revealed that the microfilaruria patients had a low weight: height ratio, deficient antibody responses in indirect haemagglutination tests with O. volvulus antigen, elevated serum aminotransferase levels, and reduced systolic blood pressure.

Splenomegaly in New Guinea.

Seeking to determine whether there is a relationship in New Guineans between hepatic sinusoidal infiltration and splenomegaly on the one hand and malaria on the other, the authors studied 24 adults from a village protected from malaria for 5 years by 6-monthly DDT spraying and 34 adults from an unprotected village with hyperendemic malaria.It was found that clinical splenomegaly tended to be associated with greater hepatic sinusoidal infiltration among persons from the malarious village and that higher malaria antibody titres were more common in patients with splenomegaly in this village. In adults in the protected village the prevalence of malaria parasitaemia was much lower than in the malarious village and the sinusoidal infiltrates were also diminished.No associations between parasitaemia, malaria antibody titre, and hepatic sinusoidal infiltration could be demonstrated in the malarious village. The implications of these findings are discussed and the question of malaria being responsible for the marked splenomegaly encountered in tropical practice is discussed.
