[For a better estimation of the prevalence of intestinal parasitism in the Tunis region]. / Pour une meilleure estimation de la prévalence du parasitisme intestinal dans la région de Tunis.

The prevalence of intestinal parasitism is generally based on the results of a single stool specimen which probably underestimates the real situation. In order to propose a coefficient for correction, we examined three stool specimens taken from 112 asymptomatic children. Intestinal parasites other than Enterobius vermicularis were detected in 29 subjects (26%). For those specimens that tested positive, 41% of children had infection detected in all three stool specimens; 21%--in two specimens and 38%--in only one. If we assume that the sensitivity of three stool specimen examinations is 100%, then the calculated sensitivity of one examination is equivalent to 68%. This gives an underestimation of the prevalence of 32%. This underestimation is not homogenous for all species. As regards Giardia intestinalis it is 35%, but for other species it would have to be calculated from a larger sample.

[Our experiences with pedicled groin flaps. Apropos of 80 cases]. / Notre expérience des lambeaux inguinaux pédiculés. A propos de quatre-vingts cas.

A series of 80 inguinal pedicle flaps was studied. These flaps were performed at the Aziza Othmana hospital in Tunis for various indications, predominantly for traumatic skin defects of the hand and sequelae of burns. This study evaluated the quality of this auto-plasty, its vascular reliability, its simplicity and the large area of skin cover available.
