World Health Organization has classified this bacterium as a Class I carcinogen. The objective of this work is to study the epidemiological, clinical and pathological aspects of Helicobacter pylori infection among adults in a digestive endoscopy unit and the pathological anatomy service of Parakou. Patients and Methods: This was a descriptive and analytical cross-sectional study conducted from January 2020 to September 2020 in the digestive endoscopy unit and pathological anatomy service at the Departmental University Hospital Center of Borgou. Patients aged 18 years and older, who had undergone a gastroscopy with biopsies and who gave their oral consent were included. Three antral biopsies and two fundic biopsies were performed. The search for Hp was done under an optical microscope after staining with hematoxylin eosin. Results: A total of 151 patients were included and 51.66% were infected with Hp. Their average age was 40.63 ± 15.32 years and the sex ratio was 0.9. Epigastric pain was the most reported symptom (71.01%). Endoscopically, the prevalence of erythematous gastropathy was 98.72%. The study of chronic Hp gastritis according to Sydney system had shown signs of activity in 100% of patients with Hp and glandular atrophy in 83.33% of them. Intestinal metaplasia and dysplasia accounted for 24.35% and 29.48% of cases, respectively. Factors associated with Hp infection were: absence of proton pump inhibitor intake prior to examination, absence of handwashing with soap and water before eating, erythematous aspect of gastritis on gastroscopy, absence of intestinal metaplasia of the fundus, active and chronic aspects of gastritis on histology. Conclusion: The frequency of Hp infection in hospitals among adults admitted to the Digestive Endoscopy Unit of Parakou is high. To reduce this prevalence, it will be necessary to act on the factors identified.展开更多

Its frequency is variable and it is considered a poor prognostic factor. In our context, when prostatic carcinoma is diagnosed, pathologists do not always report the presence of this anatomopathological entity. We therefore conducted a study to determine the epidemiological and anatomopathological profile of patients with this lesion in Dakar. Materials and Methods: This is a retrospective descriptive study covering a 1-year period from January to December 2022. It focused on cases of intraductal carcinoma diagnosed among prostatic carcinomas collected in the anatomopathology laboratories of Hôpital Général Idrissa Pouye (HOGIP) and Hôpital Militaire de Ouakam (HMO). It was based on archives of anatomopathological reports, blocks and slides. A total of 200 cases of prostatic carcinoma were collated and reviewed to identify those presenting with intraductal carcinoma according to the diagnostic criteria of Guo and Epstein. Results: 87 cases of intraductal carcinoma were found, representing 43.5% of prostatic carcinomas. The mean age was 71 years. Patients in their seventh decade were the most represented, i.e. 42.5%. The majority of samples examined were biopsies (72.4%). The mean PSA level was 965.91 ng/ml, with extremes ranging from 0.03 to 10,000 ng/ml. Histologically, 96.5% of cases (N = 84) were invasive prostatic carcinoma. Gleason score 8 (4 + 4) was the most common, accounting for 42.53% (N = 37). On average, the study found four (04) foci of intraductal carcinoma per specimen, with extremes ranging from 1 to 30. Dense cribriform architecture accounted for 78.16%, loose cribriform for 11.5%, solid for 8.04% and micropapillary for 2.3%. Six cases (6.9%) showed foci of comedonecrosis. The vast majority of radical prostatectomies (87.5%) were classified as pT3. Node invasion and perineural sheathing were observed in 12.5% and 52.32% of cases respectively. Conclusion: Intraductal carcinoma is a poor prognostic factor that must be systematically reported in the anatomopathological report. In Senegal, it is often associated with advanced stage, high-grade carcinoma and high PSA levels.展开更多
Ovarian fibroma is a tumor of the stroma and sex cords of the ovary. It is rare and represents 1% to 4% of benign ovarian tumors.

It is rare and represents 1% to 4% of benign ovarian tumors. It is sometimes associated with Demons-Meigs syndrome, raising suspicion of malignancy at the clinical and paraclinical stages. We report a case of bilateral ovarian fibroma diagnosed in the Pathological Anatomy Department of CHU Anosiala. A 46-year-old woman presented with abdominal pain and pollakiuria. Clinical examination revealed a palpable abdominopelvic mass lateralized to the right. Ultrasound suspected leiomyoma. Foci of microcalcifications were observed. The patient underwent bilateral adnexectomy. The histological study confirmed the diagnosis of bilateral ovarian fibroma. This is the first case of ovarian fibroma reported at the CHU Anosiala.展开更多

Peritoneal histoplasmosis (PH) is a rare form. The first case of PH was described in 1970 but this is the first case reported in Mauritania. We report the case of a 60-year-old male patient with a history of pulmonary tuberculosis, treated and declared cured, and partial epileptic seizures treated with <em>Carbamazepine</em>. Contrast computed tomography of the abdomen showed a large mass with a large intraperitoneal fluid component with a finely calcified wall in places, for which laparoscopy and biopsy were performed, identifying <em>Histoplasma capsulatum</em> infection. The subject received treatment with <em>amphotericin</em> <em>B deoxycholate</em> with good evolution, and outpatient management with<em> itraconazole</em>. PH is a rare entity that requires high clinical suspicion, especially in immunocompetent patients. The patient was informed that non-identifying information from the case would be submitted for publication, and he provided consent.展开更多

Methods: A retrospective review of 44 patients who underwent open AVR for aortic stenosis at a single center from 2010-2013 was performed. Patients undergoing concomitant aortic root surgery or with severe MR were excluded. MR was evaluated with preoperative and postoperative transthoracic echocardiograms. Univariate and multivariable analyses were performed to assess for factors associated with postoperative MR improvement and worsening. Results: Prior to AVR, none had severe MR, 5% (2 patients) had moderate, 9% (4 patients) mild-to-moderate, 46% (20 patients) mild, and 23% (9 patients) trace MR. Of patients with pre-operative MR, 44% (16 patients) experienced improvement of MR. Six patients had worsening of MR and the remaining 22 patients had no change. Cases of more severe MR were more likely to improve compared with mild or trace MR (P = 0.04). MR worsening was significantly more likely in patients with bicuspid aortic valves (83% vs. 24%;P = 0.004), and with larger aortic annulus diameters (P = 0.03). MR worsening was less frequent in cases of mitral annular calcification (0% vs 42%;P = 0.04) and left atrial enlargement (17% vs 65%;P = 0.03). Logistic regression analysis revealed negative predictors for MR improvement were mitral annular calcification (P = 0.04) and larger aortic annulus diastolic diameter (P = 0.05). Conclusion: Structural factors such as aortic annular size, mitral annular calcification and valve morphology may impact MR following AVR and should be investigated further as potential targets of surgical therapy.展开更多
