[Paederus dermatitis: A retrospective study of 74 cases occurring in 2008 in Guinea-Conakry].

Background: Paederus dermatitis is an unusual form of contact dermatitis caused by pederine, a secretion of insects belonging to the genus Paederus. These insects are found worldwide, although the concentration is higher in tropical and subtropical areas. Diagnosis is based on the presence of typical clinical features (erythematobullous lesions of sudden onset with a stinging, burning sensation on exposed areas of the body) combined with a compatible epidemiological context.

Ferrocene-chloroquine analogues as antimalarial agents: in vitro activity of ferrochloroquine against 103 Gabonese isolates of Plasmodium falciparum.

The in vitro activities of ferrochloroquine, chloroquine, quinine, mefloquine, halofantrine, amodiaquine, primaquine, atovaquone and artesunate were evaluated against Plasmodium falciparum isolates from children with uncomplicated malaria from Libreville (Gabon), using an isotopic, micro, drug susceptibility test. The IC(50) values for ferrochloroquine were in the range 0.43-30.

[Primary volvulus of the small intestine without malrotation. Apropos of 7 cases].

We report seven cases of complete volvulus of the small bowel without malrotation seen from 1973 through 1986. The clinical setting is always the same in this condition: the infant exhibits no clinical anomalies during the symptom-free interval between birth and the volvulus (4 h to 35 d, m = 7 d in our series). Onset is extremely sudden, with a complete, proximal obstruction, early and abundant passage of blood per rectum, and above all a severe shock that fails to respond to resuscitation.
