RESUMO

BACKGROUND: Buschke-Löwenstein tumor is a giant condyloma acuminata infection that is characterized by degeneration, invasion, and recurrence. It is associated with human papilloma virus infection. It develops around the genital and perineal area, sometimes causing a large budding ulcerated lesion. Although human immunodeficiency virus infection is frequent in Africa, there are few descriptions of Buschke-Löwenstein tumor diagnosis and its management. Screening for other sexually transmitted infections must be systematic among these patients. CASE PRESENTATION: We report herein the case of a 21-year-old African origin male patient who developed a perineal swelling. Physical examination showed evidence of a huge exophytic tumor made up of budding pinkish vegetations, with serrated crests, a ''butterfly wing'' structure, and a cauliflower-like appearance crowned with centrifugal circinate lesions. Multiple condylomatous lesions of the anal margin were also present. The patient tested positive for human immunodeficiency virus (cluster of differentiation 4 count of 119 cells/mm3) and hepatitis B infections. Real-time polymerase chain reaction revealed human papilloma virus-16 and other high-risk human papilloma virus deoxyribonucleic acid. The diagnosis of Buschke-Löwenstein tumor was made on mass biopsy, and the patient underwent multidisciplinary intervention (surgery, podophyllin application, and antiretroviral therapy). Medium-term evolution was, however, fatal due to opportunistic infection. CONCLUSION: Buschke-Löwenstein tumor is a rare tumor associated with human immunodeficiency virus infection. It is more frequent in male human immunodeficiency virus-positive patients. There is a need to screen for other sexually transmitted infections. In most cases, the treatment is surgical, in association with local therapies. However, recurrences are common.

RESUMO

Objectif Le but de notre etude etait de determiner la prevalence de l'Ag HBs chez les etudiants en medecine et pharmacie de l'universite de Douala -Cameroun. Methodes Il s'agit d'une etude transversale; descriptive et analytique qui a porte sur les etudiants de la faculte de medecine et des sciences pharmaceutiques de l'universite de Douala-Cameroun. Nous avons inclus tout etudiant regulierement inscrit et acceptant de participer a l'etude. Les prelevements etaient traites par un test rapide puis par ELISA (automatic diagnostic). Les variables qualitatives ont ete comparees par un test de Chi-2; du test de Fischer et de l'Odds ratio. Resultats Cinq cent etudiants ont ete preleves. L'age median etait de 22 ans avec des extremes allant de 16 a 31 ans. Le sex ratio etait de 1;36 en faveur du sexe feminin. L'antigene HBs etait positif chez 28 etudiants soit 5;6. 88 etudiants soit 17;6 etaient vaccines contre l'hepatite virale B. Les etudiants qui avaient recu une; deux et trois doses de vaccin representaient respectivement 5 (n=25); 7;6(n=38) et 17;6(n=88). Huit etudiants soit 4;45 avait fait un dosage de l'anticorps anti HBs pour verifier l'efficacite vaccinale. Conclusion :La prevalence de l'Ag Hbs est de 5;6 chez les etudiants en medecine et pharmacie a Douala

RESUMO

Background: Chronic hepatitis B virus (HBV) infection and cirrhosis are major risk factors for the development of hepatocellular carcinoma (HCC). In Cameroon, which is a highly endemic zone for HBV, its epidemiologic characteristics are not known. The aim of our study was to determine the epidemiologic characteristics of hepatitis B-associated HCC in our milieu for a better management of the disease. Methods: Patients suffering from HCC in two hospitals in Yaounde were sampled and screened for HBV, HCV and HDV. Only HBV related HCC were enrolled. Demographic characteristics, presence or not of cirrhosis, excessive alcohol consumption (>80g/day) and smoking were analyzed. Results: A total of 34 cases of HCC were identified. The mean age was 38.5±12.3 years (extremes 18 ­ 74 years); 79.4% (27/34) were males (sex ratio 3.9:1); 55.9% (19/34) had cirrhosis while 44.1% (15/34) were non cirrhotic. Also, 44.1% (15/34) were smokers and 2.9% (1/34) were alcoholics. The prevalence of HCC was 14.7%, 47.7%, 20.6%, 11.8% and 5.9% amongst those below 30 years, 30­39 years, 40­49 years, 50­59 years and 60 years and above respectively. There was no statistically significant difference between the mean ages of cirrhotic and non cirrhotic patients (38.9±11.3 vs. 38.0±14 years, p=0.08). The majority of patients below 30 years had no cirrhosis at the moment the diagnosis of HCC was made (80% vs. 39.9%, p=0.08). Cirrhosis was more frequent amongst those aged 30­39 years (68.8% vs. 44.4%, p=0.16). There was no other difference between cirrhotic and non cirrhotic patients. Neither alcohol nor smoking had no a synergic effect in the development of HCC. Conclusion: Most patients with hepatitis B-associated HCC in Cameroon are aged below 40 years. Cirrhosis is not always present at diagnosis. The epidemiologic profiles of cirrhotic and non cirrhotic patients are similar. The influence of alcohol and tobacco is negligible. The introduction of HBV vaccine in the extended immunization program in 2005 was thus necessary in our country

RESUMO

OBJECTIF : le rendement diagnostique de la coloscopie dépend de plusieurs facteurs, notamment les indications. La pertinence de ces indications est influencée par l'environnement économique et les structures locales. Le but de notre étude était d'analyser les indications et les résultats des coloscopies, et d'évaluer leur rendement diagnostique afin de juger de la pertinence de ces indications. MATÉRIELS ET MÉTHODES : un recueil rétrospectif de données de coloscopies réalisées de janvier 2001 à juin 2011 dans trois hôpitaux universitaires de Yaoundé a été effectué. Les variables enregistrés étaient l'âge, le sexe, les indications et les résultats. RÉSULTATS : un total de 908 protocoles de coloscopie ont satisfait à nos critères de sélection (dont 622 hommes (68,5%)). L'âge médian était de 48 ans (IQR 36-59 ans). Les indications principales étaient les rectorragies 281 patients (30,9%), les douleurs abdominales 267 patients (29,4%) et les diarrhées chroniques 107 patients (11,8%). L'examen était normal 451 fois (49,7%). Les lésions retrouvées étaient les polypes colorectaux 110 cas (12,1% ; IC 95% : 10,1-14,5), les hémorroïdes 104 cas (11, 5% ; IC 95% : 9,5-13,7), la diverticulose 71 cas (7,8% ; IC 95% : 6,2-9,8) le cancer colorectal 64 cas (7,0% ; IC 95% : 5,5-9,0) et les colites 64 cas (7,0% ; IC 95% : 5,5-9,0). Le rendement diagnostique de la coloscopie pour le cancer colorectal selon les indications était élevé en cas d'image radiologique suspecte (27,7%), de masse abdominale (25%) et d'anémie ferriprive (22,2%). les douleurs abdominales et/ou TFI non accompagnées de perte de sang macroscopique ou occulte, la constipation et le dépistage du cancer colorectal avaient un rendement faible. CONCLUSION : le rendement diagnostique de la coloscopie dans la détection des principales lésions coliques n'est pas différent dans un environnement économique défavorable malgré les indications peu pertinentes. Les symptômes digestifs avec une valeur prédictive positive élevée pour le diagnostic de cancer colorectal sont retrouvés. Les polypes et les hémorroïdes constituent les principales lésions colorectales au Cameroun. Le cancer colorectal a une prévalence élevée et inattendue méritant notre attention
