Genotypic spectrum of albinism in Mali.

Albinism is a phenotypically and genetically heterogeneous condition characterized by a variable degree of hypopigmentation and by ocular features leading to reduced visual acuity. Whereas numerous genotypic studies have been conducted throughout the world, very little is known about the genotypic spectrum of albinism in Africa and especially in sub-Saharan Western Africa. Here we report the analysis of all known albinism genes in a series a 23 patients originating from Mali.

Molecular crosstalk between the endophyte Paraconiothyrium variabile and the phytopathogen Fusarium oxysporum - Modulation of lipoxygenase activity and beauvericin production during the interaction.

Plants comprise many asymptomatic fungal endophytes with potential roles of plant protection against abiotic and biotic stresses. Endophytes communicate with their host plant, with other endophytes and with invading pathogens but their language remains largely unknown. This work aims at understanding the chemical communication and physiological interactions between the fungal endophyte Paraconiothyrium variabile and the phytopathogen Fusarium oxysporum.

Serological evidence of human hantavirus infections in Guinea, West Africa.

We recently discovered a novel hantavirus, Sangassou virus, in Guinea, West Africa. Using enzyme-linked immunosorbent assays followed by confirmatory and serotyping assays, we retrospectively detected hantavirus antibodies in 3 (4.4%) of 68 patients with fever of unknown origin in Sangassou village, Forest Guinea.

Fluctuation of abundance and Lassa virus prevalence in Mastomys natalensis in Guinea, West Africa.

Based on empiric surveillance data, the incidence of human Lassa fever (LF) cases in Guinea and other West African countries has been reported to increase during the dry season compared to the rainy season. To investigate possible links with the ecology of the rodent reservoir of the virus, we conducted a 2-year longitudinal survey of Mastomys natalensis in a region of high human Lassa virus (LASV) seropositivity in Guinea. Standardized rodent trapping with similar trapping efforts between seasons was performed in three villages and 53.

Mastomys natalensis and Lassa fever, West Africa.

PCR screening of 1,482 murid rodents from 13 genera caught in 18 different localities of Guinea, West Africa, showed Lassa virus infection only in molecularly typed Mastomys natalensis. Distribution of this rodent and relative abundance compared with M. erythroleucus correlates geographically with Lassa virus seroprevalence in humans.

[Prevalence and clinical aspects of puerperal mental disorders at the University Hospital Center of Dakar].

This is a contribution to the survey on psychiatric disorders of puerperality. We are particularly interested in the clinical signs and the ethiopathogenical facts of psychiatric disorders of the post-partum which appear-in our point of view-to be the main point on which we could probably act to reduce the effect of the disease. It is a retrospective survey going from January, 1st 1992 to December, 31st 1996.

[Self-destructive behavior in African adolescents].

The purpose of this study was to analyze self-destructive behavior in adolescents in Senegal. Based on four case reports the authors stress the central importance of family breakdown in the process leading to this behavior as opposed to the first descriptions implicating an offense against the honor of the group. The vulnerability of teenagers in the absence of structural initiation is also advanced.

Adherence to HAART and its principal determinants in a cohort of Senegalese adults.

Background: Access to programmes providing highly active antiretroviral therapy (HAART) is recent in Africa. In Senegal, a national initiative was launched in 1998. The capacity of African patients to adhere to complex antiretroviral treatments (ARV) is largely unknown.

Access to antiretroviral drugs and AIDS management in Senegal.

Objectives: Description and analysis of the Senegalese Antiretroviral Drug Access Initiative (ISAARV), the first governmental highly active antiretroviral therapy (HAART) treatment programme in Africa, launched in 1998.

Methods And Results: ISAARV was initially an experimental project designed to evaluate the feasibility, efficacy and acceptability of HAART in an African context. It was based on four principles: collective definition of the strategy, with involvement of the health professionals who would be called on to execute the programme; matching the objectives to available means (gradual enrollment according to drug availability); monitoring by several research programmes; and ongoing adaptation of treatment and follow-up according to the latest international recommendations.

[Marital conflict in Senegal: an anguished plea from the women].

Conjugopathy partner relational problem in its systemic definition is a Western concept that is only partially applicable to situations encountered in Africa. A series of 10 women were carefully studied at the Psychiatric Clinic of the Fann University Hospital Center in Dakar. In the following article the authors give a detailed description of 3 of these cases and discuss several situations characteristic of African conjugopathy: preferential, forbidden and early marriage, endogamy, non-cohabitational conjugal life, polygyny, and individual psychic vulnerability.

Why discrepancies exist between structured diagnostic interviews and clinicians' diagnoses.

The authors employed empirical methods to study the causes of discrepancies between clinicians' and epidemiologists' diagnoses of "cases" from the general population within the homogeneous DSM-III/DIS system. Four interviewers conducted 139 interviews using the DIS, while psychiatrists completed a DSM-III checklist, after which they could then ask any questions they wanted. All kappas exceeded 0.

[The patient with Hansen's disease confronts his distress].

This article is about the effect of Hansen's disease on the personality of 29 patients of the Institute of Applied Leprology of Dakar, Foundation of the Order of Malta.
