    To the best of our knowledge there is no reported case of Meckel’s diverticulum (MD) in Cameroon. The prevalence of MD in the general population is 2-3 %. The aim of this paper is to recapitulate the role of this pathology in acute abdomens and abdominal pain of uncertain aetiology in young patients and to review the medical literature

    Background: Acute appendicitis is the most frequent infectious surgical abdominal emergency and previous studies have noted the presence of parasites in the appendicular lumen.Objective: This study was done to determine the involvement of intestinal worms in the etiology of acute appendicitis.Materials and Methods: This was a prospective and descriptive study concerning cases of confirmed and operated acute appendicitis between 15th April, 2013 and 14th April, 2015 at the People’s Clinic, Ngomgham, Bamenda, Cameroon. The appendicular content was macroscopically examined for parasites and formol-ether concentration technique was carried out for ova detection.Results: A total of 112 patients were operated for acute abdominal pain within the study period. There were 74 (60.8%) cases confirmed with acute appendicitis of which 45 (60.1%) were males and 29 (39.2%) were. The most affected age group was the 21 to 40 years (50%). The removed appendices appeared congestive in 30 (40.5%) cases, suppurated in 27 (40.5%) cases and gangrenous in 17 (23.0%) cases.There was no relationship between the appearance of the removed appendix and the gender of participants (P>0.05).Three different helminth ova were identified in the 74 samples. In decreasing prevalence, the parasite trend was 8 (10.8%) Ascaris lumbricoides, 5 (6.8%) Enterobius vermicularis, 3 (6.0%), Ankylostoma duodenale, Adult Ascaris lumbricoides and Enterobius vermicularis were seen in 1 and 3 cases respectively.Conclusion: A small percentage of parasitic worm eggs were found in the appendicular content, though a good portion of patients took medications against parasites before surgery. Intestinal worms could not be incriminated in the causation of the appendicitis; nevertheless, one adult ascaris was found as an evident cause of appendicular lumen obstruction.Keywords: Intestinal Helminthes, Acute appendicitis, Bamend

    Fistule artério-veineuse ulno-basilique pour hémodialyse au CHU de Yaoundé: à propos de deux cas

    Get PDF
    La fistule ulno-basilique est une éventualité peu sollicitée dans le choix des abords vasculaires pour hémodialyse. Elle est construite sur la veine basilique qui est souvent la seule veine épargnée par les ponctions veineuses de routine dans les services de médecine. De par l'existence de nombreuses complications comme l'infection des prothèses et des cathéters centraux, les thromboses, les patients hémodialysés chroniques nécessitent plus d'un accès veineux au cours de leur suivi médical. Les fistules artério-veineuses natives présentent moins de risques de complications que les prothèses d'une façon générale et une plus longue durée de vie. La confection d'une fistule sur une topographie proximale compromet le recourt à cette veine sur une localisation distale ultérieurement. Il existe donc une hiérarchisation dont il faut tenir compte pour une utilisation optimale du capital veineux disponible. Nous rapportons ici deux observations concernant des patients chez qui deux fistules ulnobasiliques ont été réalisées avec succès au CHU de Yaoundé.Key words: Fistule artério-veineuse, hémodialyse, ponction veineus

    Adiponectin levels and its relation with insulin secretion and insulin sensitivity in a group of sub-Saharan African women with polycystic ovary syndrome.

    Low levels of adiponectin have been reported in Polycystic Ovary Syndrome (PCOS). In sub-Saharan Africa, little data are available on the topic. We aimed to investigate the levels of adiponectin and its relation with insulin secretion and insulin sensitivity in women with PCOS in Yaoundé, Cameroon. A comparative cross-sectional study was conducted in 32 women presenting PCOS and 32 controls matched for age and Body Mass Index. For each participant, adiponectin levels were measured. We estimated insulin sensitivity using Homeostasis model index (HOMA-IR) and insulin secretion with C-peptide levels. Women with PCOS had higher insulin secretion levels than controls (C-peptide: 4.98 ± 3.83 vs 3.25 ± 1.62 mUI/l; p = 0.02). Also, the HOMA-IR index was higher compared to that of women without PCOS (1.15 ± 0.90 vs 0.77 ± 0.38; p = 0.03) suggesting greater insulin resistance. The median [25th-75th percentile] values of adiponectin concentrations were similar between the two groups (22.68 [21.72-23.41] μg/ml vs 22.03 [21.40-22.93] μg/ml; p = 0.1). There was no association between insulin sensitivity and adiponectin levels in the PCOS group. PCOS is not associated with changes in adiponectin in a population of sub-Saharan African women. Further studies are needed to shed more light on this condition
