RESUMEN
The Caribbean islands are presumed to be an endemic zone for Histoplasma capsulatum infection, but no epidemiological studies have been done in this area. Our purpose was to report the epidemiology of histoplasmosis from 1991 to 1997 in the French West Indies (Martinique). Cases identified from the register of the mycology laboratory were analysed retrospectively. Ten cases (9 male and 1 female) were identified; 8 of the patients were infected with HIV (average T4 lymphocyte count in these 8 patients was 32/mm3). Eight patients had cutaneous involvement. The incidence in AIDS patients was 1.7%. The annual incidence in the general population was 0.34/100,000. Our data showed that histoplasmosis is endemic in Martinique, with an incidence in AIDS patients slightly inferior to that in endemic areas of the USA. The high rate of cutaneous forms (80%) is uncommon.

Case report of a 30-year-old patient, admitted one hour after an intentional ingestion of paraquat (60 g). The initial treatment included gastric washing, parenteral n-acetylcysteine and forced diuresis. Considering the severity of the intoxication, conventional haemodialysis was started four hours after the ingestion. Plasma concentrations of paraquat, in the lethal range at admission, decreased rapidly and significantly after haemodialysis. This case raises the question of the part played by n-acetylcysteine and haemodialysis respectively in a favourable outcome. As the determination of paraquat blood concentrations requires some delay, these data are of no help for therapeutic decisions. Therefore, in cases of massive poisoning or uncertainty of the ingested dose, a technique of blood purification in indicated. Charcoal haemoperfusion is the most efficient, however conventional haemodialysis, which is more widespread, should be considered if the former is not available.
