[Leptospirosis in a Dakar hospital: results of a new survey]. / La leptospirose en milieu hospitalier a Dakar. Resultats d'une nouvelle enquete.

The incidence of leptospirosis in West Africa is still almost unknown. Doubtful or positive serological tests were found in approx. 35% of the patients admitted to the hospital, among which leptospirosis could clinically or biologically be suspected. This rather high proportion reflects the frequency of recent or past contacts with leptospira antigen. It is in agreement with the high infestation prevalence observed among several domestic or wild animals, besides small rodents. On the countrary, it should be noted that the leptospirosis-illness, at least in its pure form, with its characteristic hepatic, renal and neurological signs, is seldom seen. Seven typical cases only (among which five at the hosptical Le Dantec) have been diagnosed in Dakar during these last 6 years. Even taking into account that the proportion of atypical, fruste or undiagnosed forms is not negligible, leptospirosis does not appear to be a major medical problem in Senegal.

[Atypical conjunctival and tonsillar locations of malacoplakia]. / Localisations atypiques, conjonctivale et amygdalienne de la malakoplakie

Conjunctival and tonsillar sites for malakoplakia have never been previously described. The diagnosis in these presented cases has only been arrived at after elimination of mycosis and parasitic disease. The aetiology remains unknown and the pathophysiology is discussed.
