RESUMEN
Congenital internal hernias often remain unrecognized since they are infrequent and produce nonspecific abdominal symptoms. Abdominal imaging during a symptomatic episode leads to the diagnosis. Surgical treatment is essential regarding the risks of incarceration. We report a case of left paraduodenal hernia misdiagnosed for over thirty years despite extensive imaging and surgical exploration.

Intra-abdominal lymphangioma is a rare congenital lymphatic vascular malformation. It is found, most commonly, in adult patients who present with abdominal pain, and whom medical imaging (ultrasound, endoscopy and tomography) reveals a cystic intra-abdominal mass. Such masses may be on the mesentery, in contact with abdominal viscera or may be part of the visceral wall. Diagnosis of intra-abdominal lymphangioma is difficult because of its rarity, and because other pathologies may have the same radiological signs. The diagnosis is confirmed by anatomopathological examination with immunohistochemistry. The treatment is complete surgical excision, in order to prevent recurrence.

An original and simple method for counting the total G cell number in the stomach of small rodents is described. Staining the G cells with the peroxidase-antibody technique and counterstaining the nucleus make it possible to correct the nuclear overestimation. Counting directly the total number of G cells in sections from the entire stomach avoids errors due to tissue retraction and to unprecise delineation of the antro-fundic limit.

A randomized un-blinded study on the treatment of oropharyngeal and esophageal candidiasis was conducted in Kinshasa (Zaire), among 141 inpatients with AIDS and oropharyngeal candidiasis, of whom 136 also had esophageal candidiasis. The study compared the efficacy of gentian violet mouth washes (1.5 ml 0.5% aqueous solution b.i.d.), oral ketoconazole (200 mg/day, after a meal) and nystatin mouth washes (200.000 U oral suspension q.i.d.). Patients treated with mouth washes swallowed their medication after mouth washing. Patients enrolled in this study had a very high mortality (probability of death: 41.6% after 14 days). After 14 days, 72 patients could be evaluated. At that time, oropharyngeal lesions had disappeared in similar proportions of patients treated with gentian violet (11/26, 42%) and ketoconazole (10/23, 43%), and in a lower proportion of patients treated with nystatin (2/23, 9%; p less than 0.05). In esophageal candidiasis, ketoconazole seemed more efficient than both other treatments: esophageal lesions had disappeared in 5 (24%) of the 21 patients on ketoconazole, compared to less than 10% of patients on both other treatments (p = 0.07). The suboptimal results observed with all 3 treatments could be explained by the profound immunosuppression of patients enrolled in the study. This study suggests that gentian violet is effective treatment for oropharyngeal candidiasis. As it is very cheap (0.5 US$/treatment course in Kinshasa), we suggest that its use should be assessed in larger studies.

Le guide pratique de la transfusion a ete concu comme un outil dont la destination est triple a savoir informer le personnel medical sur les causes d'anemie au Zaire et leur prevention; aider le personnel medical a poser correctement les indications de la transfusion sanguine de facon a eviter toute transfusion qui ne soit pas indispensable; compte tenu des risques importants de cette therapeutique et; fournir a ce personnel les informations utiles et les instructions pratiques concernant le recrutement des donneurs; les examens a pratiquer sur le sang donne; l'application de la transfusion ainsi que l'information du donneur sur les resultats des examens effectues sur son sang. Il s'adresse donc a toute personne faisant partie du corps medical et paramedical; aussi bien au medecin exercant dans un hopital qu'a l'infirmier travaillant dans un centre de sante en milieu urbain ou rural
