[Current aspects of gastric cancer in Senegal. Epidemiological and clinical study of 220 cases (1984-1991)].

220 cases of gastric cancer were selected from Dakar Hospitals during seven years (1984-1991). This retrospective study confirms that gastric cancer is the most common cancer of the Gastro-intestinal tract (48.4%). The sex ratio was 2.7 (M/F) with mean age of 50 years. However, a steady progression of gastric cancer was noticed beginning at 40 years. Despite the introduction of upper gastro-intestinal endoscopy the classical evolved form was the most commonly found (83.2%). The associated lesions known to be premalignant were found in 22.7% of cases. The patients were seen with a long delay after the first symptoms. This is why we have long delays of diagnosis in our centers. 61.7% of them are seen 3 to 12 months after their first symptoms. In 70% of cases, lesions were found on antropyloric region. The most common histological type remain adenocarcinoma (90% of cases). Even though endoscopy has contributed to increase the incidence of gastric cancer, it did not allow to discover early gastric carcinoma.

[A case of joint toxicity from pefloxacin in the treatment of nephrotic syndrome in a child].

In order to improve the nephrotic syndrome management, we tried to treat one patient by pefloxacin. A polytenosynotis was noticed during this treatment and motivated it stopping. Remission of proteinuria was obtained after an eleven days treatment. This case give us the opportunity to discuss the possible toxicity of quinolones on joints and the efficacy of pefloxacin in this disease.

[Contribution of echography in the diagnosis ruptured liver abscess (Apropos of 4 cases)].

The authors report 4 cases of ruptured hepatic abscesses in peritoneum (2 cas) and in pleural (2 cases). The cases occurred in 3 men (two of them were alcoholic) and one woman who was in the postpartum period. The cases confirm the classic pictures according to which, ruptures of hepatic abscesses have unclear clinical presentation whether they are amoebic or bacterial in origin! In these cases, ultrasound is very useful in the rapid detection of peritoneal or pleural abscesses which can be confirmed by ultrasonically guided fine needle punction When the channel from the intra hepatic abscess can be visualised, or when they are a coexisting hepatic and peritoneal pleural abscesses, the diagnosis is clear. However when the abscess has been completely emptied of its contents the diagnosis may the difficult.

[The C virus in Africa].

C virus (HCV) main responsible of non A - non B hepatitis appears to be rather frequent within the world population African continent seems to possibly be situated in the high prevalence zones of antibodies HCV carrying. Detection methods of these antibodies have been polished but very fragmentary studies on African populations do not permit to conclude with certainety about the prevalence rate of this virus. However, it appears that concentrations of antibodies detected during chronic hepatopathies might be similar in Europe and in Africa. An epidemiological study on representative samples of the African population seems to be necessary to appreciate the importance of this infection and to monitor its transmission.
