[Intestinal parasitic diseases in an urban environment in Sahel. A study in a district of Niamey, Niger].

Health and environment in Niamey, a capital in Sahel, are particularly linked owing to population growth, promiscuity and large pollution induced by human and animal excreta. One district, located in the centre of the town, was surveyed for drinking water quality (ammoniac and bacterial count) and use, as well as for the prevalence of parasites through both a random sample (fixed tools with methiolate-iodine-formaldehyde) and a systematic one (scotch-test). Water consumption was 16.5 litres/day/man from fresh water supplies (87%) and private wells (13%). Ammoniac measures were low in the wells but high in running water (pool and river). It was the same for faecal coliform bacteria. These results give evidence of biotope faecal pollution. The random sample (322 persons, male/female sex ratio 0,85, average age 20,6 years) showed a 42.1% parasitic prevalence. Amoeba was the most frequent parasite (53.6%); and Giardia (14.9%) was the most frequent pathogenic parasite. In the second sample (161 children under 10 years), 24.2% were carriers of oxyuris. This large intestinal parasitism, without any change in connection with previous data in Niger, points to an important fecal contamination of the people more by the way of "dirty hands" than consumption of drinking water. The parasites observed have a short biological cycle, not necessitating long-term maturation in the environment. Those whose ova or larvae must complete their cycle outside have no possibility of surviving in Sahel, thanks to the beneficial effect of sunlight (heat and ultraviolet light). The inhabitants of this district seem to have adapted to intestinal parasitism. But the occurrence of malnutrition linked to a new drought could lead rapidly to a very serious adverse result.

Studies in intestinal parasitic disease agents in stools of people in a rural area of Nigeria.

A summary of 300 villagers who reported at the Parasitology Laboratory of the School of Medical Laboratory Technology (S.M.L.T) Vom, Plateau State, Nigeria was carried out for the presence of parasites' cysts, eggs, or larva. Of the 300 faecal samples examined using the light microscope after formal-ether centrifugation, 127 (42.3%) harboured one or more parasites. The parasites identified and their prevalent rates were: Entamoeba coli (19.0%) Necator americanus (17.0%); Entamoeba histolytica (4.7%); Schistosoma mansoni (3.0%); Giardia lamblia (2.3%); Trichuris trichuria (1.7%); Trichomonas hominis (1.0%); Ascaris lumbricoides (0.7%); Hymenolepsis nana (0.3%) Endolimax nana o. 3%); stercoralis (0.23%), and Iodamoeba butschlii (0.3%). The overall infection was 22.7% for the males and 19.7% for the females. Incidence was highest in villagers aged between 21 and 40 years.

[Intestinal parasitic diseases of school children in the Republic of Niger].

Coprologic surveys realized in schoolchildren in a few western areas of the Republic of Niger provided the following results. Concerning protozoa, the prevalence of amebiasis-infestation is strong in all the studies areas, giardiasis is more frequent in dry areas. As for the helminths, Hymenolepsis nana is met everywhere, the prevalence of ancylostomiasis decreases gradually from the south to the north and the endemic area of Schistosoma mansoni is limited to the extreme south of the country. The other helminthiasis are rare.

[Absorption of D-xylose in intestinal parasitic diseases].

In order to investigate the intestinal absorption in relation to parasitic diseases, 106 children were studied using the xylose test. All of them were attending a primary school. The height and weight were recorded, and the hemoblobin and hematocrit were estimated in each one. The examination of the stools shown one or more parasites in 57.6 per cent specimens. The E. histolytica, Hymenolepis nana and A. lumbricoides, were identified in 22.6, 21.7 and 20.7 per cent children, respectively; G lamblia was found in 10.4 per cent. Only the children with Giardia had a statistical difference in the absorption of xylose, with respect to those without parasites. At the same time height was low in comparison to a group of children with similar age and sex, selected among the 45 without parasitic diseases. Findings are discussed according to the pathogenic mechanism involved in giardiasis. Emphasis is done in the interplay of malnutrition and G. lamblia.

Binge eating disorder onset by unusual parasitic intestinal disease: a case-report.

We report a case of binge eating disorder (BED) in a 19-year-old Spanish woman, whose onset followed a nowadays uncommon parasitic intestinal disease (Taenia solium by cysticercosis). The patient exhibited bizarre and frequent hyperphagia episodes and extreme loss of weight, common symptoms of this condition. The patient continued to have frequent binge episodes and inappropriate eating patterns, gaining weight consequently over a normal range, despite successful treatment of the condition. No purging behavior was detected. A classical conditioning behavioral model, was useful for the understanding and formulation of this case. To the authors' knowledge, this is the first reported case where a parasitic infestation triggered the onset of BED.
