Burkitt's lymphoma in Cameroon: a review of 300 cases in two referral health facilities in Yaounde / G. E. Enow-Orock  

Public ISBD Title : Burkitt's lymphoma in Cameroon: a review of 300 cases in two referral health facilities in Yaounde Authors: G. E. Enow-Orock ; B. Tchemtchoua, Author ; N. P. Koki, Author Publisher: Yaounde [Cameroon] : Association of Cancerology and Pathology Publication Date: 2012 Series: African Journal of Pathology and Microbiology, ISSN 2090-9039 No. 1 Pagination: p.1-4, tab. Layout: Journal Article ISSN (or other code): 2090-9039 Languages : English Keywords: Burkitt Lymphoma  Health Facilities  Case Reports - Review  Yaounde - Camerouun Abstract: In this descriptive retrospective study; we reviewed 300 cases of Burkitt's lymphoma (BL) diagnosed within 10 years from January 1; 2000 to December 31; 2010. The study took place in the pathology laboratories of the Central Hospital and the General Hospital in Yaounde; Cameroon. The aim was to review the anatomo-clinical and epidemiological aspects of the disease; especially with respect to its localization. We found that BL affected mostly children aged 5-14 years with peaks at 4 and 12 years. A slight male predominance was observed. The abdomino-pelvic site was more frequent (57.7%). Diagnosis of the tumor was mainly by fine-needle aspiration cytology (FNAC). About 6% of our patients tested positive for the human immunodeficiency virus (HIV). We recommend further in-depth studies to find out if there are any emerging factors that influence the localization of the disease in endemic areas or if our finding is incidental.

Layout: Journal Article ISSN (or other code): 2090-9039 Keywords: Pseudomonas aeruginosa  Résistance bactérienne aux médicaments  Phénotype  Infection croisée  Cameroun - Yaoundé Abstract: Introduction. L'objectif etait de determiner la proportion de souches de Pseudomonas aeruginosa (P. aeruginosa) exprimant des mecanismes de resistance dans la ville de Yaounde. Methode. Il s'agissait d'une etude prospective et descriptive realisee du 02 janvier au 30 juin 2012. Des souches de P. aeruginosa provenant de divers produits pathologiques de patients ont ete identifiees a l'aide de la galerie API 20NE (Biomerieux). Pour les prelevements urinaires; une cytologie etait faite pour verifier l'absence de cancer. La lecture interpretative de l'antibiogramme a ete faite par diffusion sur gelose Mueller-Hinton selon CA-SFM 2011. Resultats. Au total 34 souches de P. aeruginosa ont ete isolees dont 85;3?% chez patients hospitalises. Parmi ces souches; 41;2?% etaient isolees des urines; 23;5?% des hemocultures et 17;6?% des suppurations. Les urines montraient a l'examen cytologique des modifications inflammatoires aigues et l'absence de cancer. Le profil de resistance aux antibiotiques a montre une resistance elevee preferentielle des Beta-lactamines notamment a la ticarcilline (35;29?%). Concernant les Beta-lactamines; les phenotypes les plus observes ont ete pour les 2/3 sauvages et 26;5?% pour les penicillinases ; quant aux aminosides 94;1?% etaient de phenotype sauvage; tandis que 2/3 etaient de type sauvage pour les fluoroquinolones. Conclusion. Une association Beta-lactamines/aminosides ou Beta-lactamines/fluoroquinolones pourrait etre preconisee afin de lutter contre toute infection a P. aeruginosa.

Cornual molar ectopic pregnancy: a case report with difficult management in poor resources settings / Bruno Kenfack

Layout: Journal Article ISSN (or other code): 2090-9039 Languages : English Keywords: Pregnancy Cornual  diagnosis  Gestational Age  Disease Management  Case Reports Abstract: Molar pregnancy is a rare entity and ectopic location of pregnancy in the uterine horn represents the least frequent site of implantation. This paper presents a rare case of molar cornual ectopic pregnancy at advanced gestational age with a particular difficulty in diagnosis and management. A 35-year-old woman; gravida 4 para 3 with a history of 12 weeks amenorrhea; was operated for presumed ruptured ectopic pregnancy. Per-operative findings showed swollen villi in clusters that looked like bunches of grapes; characteristic of a complete hydatiform mole; located at the left horn of the uterus. Histopathologic examination confirmed the diagnosis. Bleeding could not be controlled with suturing and hysterectomy was eventually done. Although rare; molar pregnancy can be ectopic. If it is located at the uterine horn; bleeding may be difficult to control if at a gestational age of 12 weeks or more.

Helicobacter pylori cagA Gene in Egyptian sewage workers / Salah Agha  

Public ISBD Title : Helicobacter pylori cagA Gene in Egyptian sewage workers Authors: Salah Agha ; Mona F. Foad, Author ; Nabil J.

Layout: Journal Article ISSN (or other code): 2090-9039 Languages : English Keywords: Caga protein  Helicobacter pylori - Helicobacter pylori  Sewage  Occupational Exposure  Egypt Abstract: A comparative cross-sectional study was conducted on 60 sewage workers and 30 matched unexposed referents from Mansoura city; Egypt; to estimate the prevalence and risk factors of Helicobacter pylori (H. pylori). Stool culture and detection of H. pylori antigen were done. In addition; the polymerase chain reaction (PCR) amplification of cytotoxin-associated gene A (cagA) gene in H. pylori in stool samples was carried out. The prevalence of H. pylori in sewage workers was 56.7% compared to 16.7% in the comparison group with a highly statistically significant difference between both groups. H. pylori cagA gene was present in 64.7% of H. pylori-infected sewage workers compared with 40% of controls. cagA gene was associated with more dyspeptic symptoms (77.3%) in infected workers compared to those of noninfected ones (33.3%) (P = .041). The risk of H. pylori was significantly higher among workers with poor compliance with personal protective equipment (PPE) (OR = 3.00); with duration of work 20 years (OR = 4.71); older than 45 years (OR = 4.27); and of low education level (OR = 11.2). We concluded that H. pylori infection and heartburn with or without epigastric pain are significant health problems in the studied sewage workers. Low education and poor compliance with PPE were the only predictors of H. pylori infection in sewage workers.
