The Kandi basin is located in northeast Benin (West Africa). This study is focused on the estimation of water fluxes exchanged between the river Niger (and its tributaries) and the transboundary Iullemeden Aquifer System. In that framework, an innovative approach based on the application of the Bayesian Mixing Model (MixSIAR) analysis on water isotopes (oxygen-18, deuterium and tritium) was performed. Moreover, to assess the relevance of the model outputs, Pearson’s correlation and Principal Component Analysis (PCA) have been done. A complex relationship between surface water and groundwater has been found. Sixty percent (60%) of groundwater samples are made of more than 70% river water and rainwater;while 31.25% of surface water samples are made of about 84% groundwater. To safeguard sustainable water resources for the well-being of the local communities, surface water and groundwater must be managed as a unique component in the Kandi basin.

Introduction: Pregnancy, childbirth, and their consequences continue to be the leading cause of death, illness, and disability among women of reproductive age in developing countries. In Niger, maternal deaths account for about 39% of all deaths of women aged 15-49. Our aim was to identify the factors linked to maternal mortality in order to contribute to its reduction. Method: this is a descriptive retrospective study of 379 cases of maternal deaths collected at the Maradi CSME from January 1, 2018, to December 31, ***: Our study’s maternal mortality ratio is 2645.72 per 100,000 live births. The mean age of our patients was 27.46 years, with extremes ranging from 15 to 47 years. The 20-24 age group was the most represented, with 88 cases (23.2%). Housewives were 361 (95.3%), and 334 patients (88.1%) were uneducated. There were 261 of them from rural areas, i.e. 69%. The mean parity in our study was 3.46, with extremes ranging from 0 to 15. Multiparous patients 117 cases (30.9%) represented the most significant proportion. Only 42 patients (11.08%) had performed four or more antenatal consultations. Direct obstetric causes accounted for 56.73% of the causes of maternal death. Anemia was the leading cause of maternal death (31.66%). Nearly half of the patients had died before 24 hours after admission, i.e. 49.86%. Conclusion: Maternal mortality remains a significant challenge for developing countries, given its magnitude and timid decline. The fight to reduce maternal mortality must be the priority of our countries’ health policies.

Introduction: Emergency obstetric hysterectomy (EOH) is a lifesaving procedure that is performed as a last resort in cases of severe postpartum haemorrhage. Objective: The objective of this study was to determine the incidence, socio-demographic profile of patients, indications, management and maternal-fetal outcomes of EOH in a maternity hospital with limited resources in Niger. Methodology: This was an eight-year retrospective cohort study involving the analysis of medical records from patients who underwent emergency obstetric hysterectomies between 1 January 2015 and 31 December 2022 at the Mother and Child Health Centre (MCHC) in Maradi, Niger. The epidemiological data, indications, and outcomes of EOH were collated and subjected to analysis using the statistical software package SPSS 21.0. Comparisons were made using the Chi-squared test. A p-value of less than 0.05 was considered statistically significant. Results: During the study period, 239 cases of emergency obstetric hysterectomy were recorded out of 269,710 deliveries, representing a frequency of 0.89%. The mean age of the patients was 32.41 years (range: 17 - 50 years). The patients were identified as married (239 cases, 100%), unemployed (228 cases, 95.4%), and not attending school (215 cases, 90%). The largest number of cases were observed in large multiparous women (i.e., those with more than five children), representing 58.6% of the total number of cases (140 patients). The average parity among this group was 6.15 children. The majority of patients (229 patients, 95.82%) had undergone in utero transfer, with 169 patients (70.71%), originating from peripheral maternity units in the Maradi region. Upon admission, 116 patients (48.53%) exhibited active genital haemorrhage, while 58 patients (24.26%) were in shock. The primary indications for hysterectomy were uterine rupture (153 patients, 64%), uterine atony (77 patients, 32.2%), and placental accreta (six patients, 2.5%). Hysterectomy was performed

Background: Surgical site infections (SSIs) are considered as result of the healthcare quality in hospitals. Objective: to study SSI at Saint Jean de Dieu Hospital Tanguieta (SJDHT), prior to the implementation of a permanent monitoring system. Method: transversal, and descriptive study with prospective data collection was performed from 1 July to 31 janvier 2017 in the department of general surgery of SJDHT. The hospital lacks in a microbiology unit. All patients who underwent surgery during this period were included and the monitoring lasted one month. SSIs diagnostic was carried out according to WHO criteria as described in the Practical Guide for the Prevention of Nosocomial Infections published in 2002. Statistical tests (χ-square and Student’s t-test) were applied and p 0.05 were statistically significant. Results: Of 343 patients recorded, 105 (30.6%) had SSI. Their age averaged 40.3 years and the sex-ratio (men/women) was 2.8. The emergency surgery resulted in a 50.0% rate of SSI (p = 0.00). The SSI rate for clean and clean-contaminated surgery was 6.3% against 94.6% for infected surgery (p = 0.00). The SSI rates were 100% and 66.7% for NNISS = 2 and NNISS = 1 (p = 0.00), respectively. Superficial SSI rate was 13.3%, while deep SSI and organ/space SSI were 46.7% and 40%, respectively. The hospital stay of patients with SSI was three times longer than the length of patients without SSI (p = 0.00). Conclusion: SSIs are real burden at SJDHT. Appropriate measures must be adopted to reduce its prevalence.

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.
