In Morocco, between March and April 2002, large numbers of human leihsmaniasis cases were detected during a survey at Zouagha My Yacoub province in Fès State. Among 95 cases, 76 were positive by direct observation of Giemsa-stained smears. Sixteen stocks were isolated in NNN medium and identified as Leishmania tropica MON-102, using isoenzyme techniques on starch gel electrophoresis.
The morpho-costitutional analysis of 574 urinary lithiasis emitted by tunisean adults permitted to define an épidemiology's profile. This resemble to the épidemiology's profile of under-developed conry: Amore raised frequency of the renal lithiasis at the man than at the woman with a sec ratio of 2.4. An average age of +14 years with a peak to 4th decade in 2 sexes. The upper localitation of the calculi is founded in 94% cases. The fréquency of the relapses, the mode of expulsion and the size of calculi are différent of those published in the litérature. Probably because the time of study which last 4 years is too short, so it don't enable us to find a result like the literature. The surgery is the mode of most fréquent élimination (51%). This s dû to the présence great size calculi in our popûlation and to the récent introduction of the lithotritie in our country.

We analyzed the relationship between the evolution of pregnancy and the amplitude of the lipid disorders in order to evaluate their chronologic transformations. This research concerned 83 pregnancies aged between 19-40 years during the 3 periods of gestation and 31 healthy control women in the same range of age. Our results showed an increased triglyceride in the 2nd period and an earlier decrease of both, cholesterol, phospholipid and apolipoproteins. These parameters showed a progressive increase of their blood concentrations during the 2nd and the 3rd period of pregnancy, in an other hand we evidenced a good correlation between gestational aged and these variations i.e.: triglyceride and mother's weight; this phenomenon could suggest an eventual role of the nutrition and the hygienic habitude in the lipid metabolism. The correlation between our observed lipid disorders and the mother's age or the parity were not significant.

Importance of streptococcal pharyngitis rapid diagnosis is increasing. 645 patients with pharyngoamygdalitis were tested. The correlation between bacteriologic culture and rapid test is 86%, the sensibility of the test is 68%, its specificity is 92%, while the predictive positive and negative values are 75% and 90%. These results show the interest of the rapid test for the diagnosis of streptococcal pharyngitis.
