Urinary and intestinal schistosomiasis are both endemic in Niger with a dominance of Schistosoma haematobium. This study pointed out the appearance of the infection to S. mansoni in the Niger River valley, where it was until then unknown in Niger. In one year the prevalence increased from 5.9 to 19.5%.
Located in an area where Schistosoma haematobium is hyperendemic, the town of Niamey is a focus of hypoendemicity. The aim of the malacological follow-up studies undertaken over a one year period was the determination of the mollusc species present in the water bodies, the appreciation of their space-time distribution of the snail and to find out the(More)
Malacological monitoring of two irrigated areas in Niger highlighted the natural susceptibility of Bulinus forskalii to infection with Schistosoma haematobium when the parasitic load is high. This first report of S. haematobium infection in B. forskalii, which is an abundant snail in irrigated areas, has been confirmed experimentally.
Heterogeneity of Schistosoma haematobium transmission in irrigated fields. Although irrigated areas exist since a long time in the Niger Valley the distribution of the urinary schistosomiasis does not appear homogeneous, testifying to the existence of limiting or favourable factors. The identification of these factors could lead to a better definition of(More)
BACKGROUND Currently, the control of urinary schistosomiasis is mostly based on mass treatment. Characterization of Schistosoma haematobium transmission could lead to adding new methods to the control strategy. METHODS We carried out malacological and cercariometrical surveys in irrigated perimeters of the Niger River valley. A semi-monthly follow-up was(More)
Prolymphocytic leukemia T (PLL-T) is a rare entity of mature lymphoproliferative syndrome, characterized by its evolution but especially by its poor prognosis. It is usually revealed by hyperlymphocytosis in the blood. We report a case of prolymphocytic leukemia T, revealed by blood hyperlymphocytosis higher than 800 G/L, diagnosed at the My Ismail military(More)
Medullary aplasia (MA) is a rare and severe affection. It is much rarer in children. The etiologies are multiple: constitutional, acquired, and idiopathic. In order to evaluate the epidemiological, clinical and biological aspects of bone marrow aplasia in a pediatric population, we carried out a retrospective study of 9 cases collected in the hematology(More)
Intrinsic vector characteristics and environmental factors affect the sporogonic development of P. falciparum in Anopheles mosquitoes. We tested for the presence of the circumsporozoite protein, as a marker of the oocyst to sporozoite transition in naturally infected Anopheles gambiae s.l. and Anopheles funestus. Malaria vectors were collected in a village(More)
The Neurosyphilis is the most severe neurological complication of the active syphilis. It puts real diagnostic problems because of the ascendancy of the atypical forms. Our objective is to analyze the clinical symptoms and to assess the relevance of the different laboratory findings in cerebrospinal fluid (CSF) and serum for the diagnosis and survey of(More)
INTRODUCTION Geophagy or soil eating is mostly described in pregnant women from Sub-Saharan Africa, South America. Here, we report 12 cases of geophagy associated with severe anemia in non-pregnant Nigerian women. RESULTS/CASE REPORTS The median age at diagnosis was 34.5 years. The socioeconomic level was average for all patients. The median hemoglobin(More)
