[Malaria indices, larval ecology and trophic activity of Anopheles mosquitoes in Djohong (Adamaoua, Cameroon) in the rainy season].

In Djohong in the wet season the prevalence of malaria is 17.5% for Plasmodium falciparum and 1.1% for Plasmodium malariae.

Trends of human immunodeficiency virus type-1 infection in female prostitutes and males diagnosed with a sexually transmitted disease in Djibouti, east Africa.

A cross-sectional serosurvey for human immunodeficiency virus type 1 (HIV-1) was conducted during the first quarter of 1991 among high risk groups in Djibouti, East Africa, and compared with previous surveys in 1987, 1988, and 1990. The survey demonstrated evidence of HIV-1 infection in 36.0% (n = 292) of street prostitutes, 15.

[Infection by the human immunodeficiency virus in the Republic of Djibouti: literature review and regional data].

The first evidence of HIV infection in Djibouti, East Africa, was found in the spring of 1986; the first case of acquired immunodeficiency syndrome (AIDS) was diagnosed in March 1988; and, as of the end of 1991, 104 cases of AIDS had been reported. HIV-1 infection was predominant. Previously published results of four serosurveys carried out in October 87, June 1998, February 1990, and from January 1991 to April 1991 among high risk groups are presented and compared.

[Prevalence of infection by the human immunodeficiency virus (HIV) in a target population in the Republic of Djibouti].

The Prophylaxis Center of the Republic of Djibouti reports a prevalence investigation about AIDS seropositivity from January to May 1991 at risk people: the "street" prostitutes and "bar" prostitutes in Djibouti town. This serological investigation confirmed by WESTERN-BLOT technique shows the quick-growing of AIDS seropositivity in Djibouti.

[Plasmodium falciparum travels by train from Ethiopia to Djibouti].

To investigate the role of the Djibouti-Ethiopian railway as a potential vehicle for inter-regional spread of malaria vectors and malaria parasites, we performed a double-sided study, both entomological and parasitological, during November 1989, at the frontier post of Guelile where the trains from Ethiopia enter the Republic of Djibouti. No malaria-transmitting mosquitoes were collected either from the daily passenger train or from the weekly vegetables train. One hundred and five passengers entering Djibouti by train from Ethiopia had a thick film examined for malaria parasites.

Evaluation of the treatment of intestinal helminthiases with albendazole in Djohong (North Cameroon).

246 inhabitants of Djohong, a township located in North-east Cameroon, presented with single or mixed nematode infections. They were treated by 400 mg albendazole in a single dose. The results were evaluated either with the Kato thick-smear technique and the Ritchie technique on stools and/or the Graham test: albendazole has proved to be 100% efficacious in pinworm and roundworm treatment, 63% to 84% in hookworm treatment (difference due to the type of technique used).

[Halofantrine in the treatment of malaria. Clinical trial in a semi-rural zone of Cameroon].

Twelve children, 2 to 15 years of age, with falciparum malaria (parasitaemia 4,500 to 170,000/mm3) have taken 24 mg/kg body weight of halofantrine hydrochloride (Halfan) per os in three divided doses given within 12 hours. The symptomatology improved after 24 to 48 hours, with no more fever 5 to 90 hours after treatment and with a decrease of splenomegaly in 80% of the cases. The parasitic clearance was obtained after 24 to 60 hours.

[Influence of acute exertion and physical training on platelet function of the coronary patient].

The platelet function, fibrinogen level, and the various lipid fractions were studied in 17 coronary patients before, during and after a maximal effort, both before and after a three month period of physical training. Exercise capacity increased by 26%, stickiness went down by 27% at rest (p less than 0.025) and 42% on exercise (p less than 005), and aggregation varied (according to the method used) between 24%, 25% and 2% at rest (p less than 0.
