Introduction: Elderly people are considered fragile and at greater risk of having malignant gastrointestinal tumors. The objective of this work was to report the reasons for performing gastrointestinal endoscopy and the lesions found during the endoscopy of this target population in Parakou. Patients and Study Methods: This was a descriptive and cross-sectional study with a retrospective collection of data from January 2016 to December 2017, then from January 2020 to December 2021. It took place in the regional Teaching Hospital of Borgou-Alibori in Parakou and in the private gastrointestinal endoscopy center of Parakou (Northern Gastrointestinal Exploration Center). All patients aged at least 60 years who had undergone an upper gastrointestinal endoscopy during the study period were included. The variables studied were: the sex, age, indications for the examination, endoscopic lesions and data from the anatomo-pathological examination. results: In total, out of 1540 upper gastrointestinal endoscopies performed during the study period, 249 (16.17%) involved patients aged 60 years and over. The sex ratio was 1.26. The main indication for the examination was epigastric pain (123 cases, i.e. 49.40%) followed by vomiting (53 cases, i.e. 21.29%). In terms of lesions, non-tumorous gastropathy came first in the stomach (206 cases, i.e. 82.73%) while esophageal lesions were dominated by esophageal candidiasis and cardial incompetence (39 cases, i.e. 15.66% in each of the two situations). In the duodenum, ulcer was noted in 30 patients (12.05%). In 38 patients, 12 (31.58%) were tested positive for Helicobacter pylori infection. Cancers of the gastrointestinal tract were confirmed in 11 patients (4.42%). Conclusion: Upper gastrointestinal endoscopy remains an excellent examination for the exploration of the upper gastrointestinal tract. In Parakou, epigastric pain represents the main indication for this examination in subjects over 60 years of age. Inflammatory or ulcerated n

Background: Cervical cancer (CC) is the fourth most common cancer in women and those living with HIV have a six times higher risk of cervical cancer compared to those without. The objective of this study was to assess knowledge and perceptions about cervical cancer in women living with HIV/AIDS (WLWHIV) in the municipality of Parakou in Benin. Methods: This was an analytical cross-sectional study conducted among WLWHIV monitored on antiretrovira (ARV) therapy (ART) centers in Parakou. Study participants were selected by systematic random sampling technique. Data collection took place from September 5, 2017 to November 6, 2017. Log-binomial regression was used to identify associated factors. results: A total of 167 women were recruited into the study. The median age was 35 years [Interquartile range: 41.50 - 30.00]. More than half of the women had no perception of the cause of CC. Only 12.6% of women believed in the preventive capacity of early screening of CC. Among women, 15.6% knew that it can be prevented, but only 9.6% had heard of HPV and 4.8% knew that HPV vaccination is an effective means of preventing CC. The factors associated with the low level of knowledge were the age at first sexual intercourse (≤24 years), the ART follow-up site (private health structure) and the fact of not having visited a maternity hospital in the last 12 months preceding the survey. Conclusion: The perceptions and knowledge about cervical cancer in the population of women living with HIV and monitored on ART in Parakou were inadequate and disproportionate to their vulnerability to this cancer. In order to avoid a double burden on these women, their ART centers must integrate cervical cancer prevention interventions into ART initiation services.

Introduction: Helicobacter pylori (Hp) infection is the most common bacterial infection in the world. 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.

Background: Breast cancer is a life-threatening pathology affecting women across the world. Evidence suggests deficiency of knowledge and numerous sociodemographic factors contribute to delayed medical attention seeking behavior whether initial symptoms of breast cancer go undetected. Objective: This study aimed to assess knowledge, attitudes and practices regarding breast cancer among Parakou University female students in 2021. Method: This was a cross-sectional study with descriptive and analytical purposes, carried out on the campus of the University of Parakou, from June 14 to July 2, 2021. Data collection was performed through an individual online questionnaire, designed with KoBoCollect version 1.29.3. Data analysis was implemented with EPI INFO VERSION 7.***.3.3 software. result: A total of 200 students meeting the inclusion criteria participated in this study. Among them, 20.5% had never heard about breast cancer. Non practice of breast cancer screening (breast self-examination) prevalence was 80%. Factors favoring non practice of breast cancer screening were: ethnicity, religion, not adhering to screening ideas, not committing to educating family and friends about screening. Factors promoting breast cancer screening practice were: having ever heard about breast cancer, being able to point to breast cancer symptoms, having adequate knowledge of breast cancer screening methods, having a good knowledge of the late-stage screening drawbacks. Conclusion: Some young women with high school level are still unaware of breast cancer and do not practice screening. Policymakers should consider more effective information outreach.

Background: Gastritis is better evaluated nowadays since the advent of upper gastrointestinal endoscopy. Despite the availability of this workup in Benin republic, there is a scarcity of data on chronic gastritis. Objective: This work aimed to study the epidemiological and histopathological aspects of chronic gastritis in the Departmental University Teaching Hospital of Borgou Alibori (CHUD-B/A) from 2011 to 2021. Method: This was a retrospective cross-sectional study with descriptive and analytical purposes, carried out from February 23, 2022 to May 23, 2022, among patients who had undergone gastric biopsy and/or gastrectomy from January 2011 to January 2022 (10 year), and whose specimens were sent into the histopathology section of the CHUD-B/A. Non-probability sampling was performed with exhaustive recruitment. A survey form has been used to collect data from patients’ medical records. Pearson’s chi-square and Fisher’s exact tests have been used as appropriate to determine correlations between variables. result: A total of 310 cases of chronic gastritis were diagnosed in the histopathology section of the CHUD-B/A from 2011 to 2021. This represented a chronic gastritis frequency of 91.45% for all gastric lesions diagnosed throughout the study period. Erythematous gastropathy was the most frequent (70.35%). Helicobacter pylori was present in 36.77% and dysplasia was observed in 12.26% of cases. Erythematous gastropathy was a predictive factor for the absence of gastric dysplasia in histopathology check up (p-value = 0.042). In contrast, intestinal metaplasia was predictive of the presence of gastric dysplasia in histopathology check up (p-value < 0.001). Conclusion: Chronic gastritis is very common in our setting. Systematic biopsy performance in front of an evocative clinical situation followed by histopathological examination may be encouraged.

Background: Breast cancer mortality remains high in the majority of developing countries. The Ministry of Health has established two population-based cancer registries in Benin: the first one in Cotonou in 2014 and the second one in Parakou in 2017. However, there is a scarcity of data on breast cancer survival and prognosis in Benin republic. Objective: This study sought to investigate epidemiological, diagnostic, and survival aspects of breast cancer in Parakou, based on data from its population-based cancer registry from 2017 to 2021. Method: For descriptive and analytical purposes, we used a retrospective cohort design. From January 24, 2022 to August 31, 2022, data were collected in all health facilities covered by the Parakou population-based cancer registry using an individual questionnaire. Survival and prognosis analysis were performed using KAPLAN MEIER method and David COX proportional hazard model respectively. result: A total of 81 patients have been included in this study. The incidence rate of breast cancer in Parakou was 17.5 per 100,000 person-years with a mortality rate of 2.76 per 100,000 person-years. The median age at diagnosis was 44.50 years with extremes ranging from 19 to 76 years and a predominance of 40 - 50 years age group. The median survival time was estimated at 30 months with an overall 5-year survival of 47%. Young age at diagnosis (p-value = 0.002) and advanced stage at diagnosis (p-value = 0.000) had a negative impact on survival in women. The combination of surgery and chemotherapy improved survival (p-value = 0.018). Conclusion: Breast cancer is still a public health issue in Parakou. It comes out mandatory that resources be made available to make screening, early diagnosis and appropriate treatment of breast cancer affordable.
