Background Tuberculosis (TB) remains a major public health problem in Nepal, high in settings marked by prevalent gender and social inequities. Various social stratifiers intersect, either privileging or oppressing individuals based on their characteristics and contexts, thereby increasing risks, vulnerabilities and marganilisation associated with TB. This study aimed to assess the inclusiveness of gender and other social stratifiers in key health related national policies and the Health Management Information System (HMIS) of National Tuberculosis Programme (NTP) by conducting an intersectional analysis of TB cases recorded via *** A desk review of key policies and the NTP’s HMIS was conducted. Retrospective intersectional analysis utilized two secondary data sources: annual NTP report (2017–2021) and records of 628 TB cases via HMIS 6.5 from two TB centres (2017/18–2018/19). Chi-square test and multi-variate analysis was used to assess the association between social stratifers and types of TB, registration category and treatment *** Gender, social inclusion and concept of intersectionality are incorporated into various health policies and strategies but lack effective implementation. NTP has initiated the collection of age, sex, ethnicity and location data since 2014/15 through the HMIS. However, only age and sex disaggregated data are routinely reported, leaving recorded social stratifiers of TB patients static without analysis and dissemination. Furthermore, findings from the intersectional analysis using TB secondary data, showed that male more than 25 years exhibited higher odds [adjusted odds ratio (aOR) = 4.95, 95% confidence interval (CI): 1.60–19.06,P = 0.01)] of successful outcome compared to male TB patients less than 25 years. Similarly, sex was significantly associated with types of TB (P < 0.05) whereas both age (P < 0.05) and sex (P < 0.05) were significantly associated with patient registration category (old/new cases).Conclusio

Introduction: Peritoneal dialysis (PD) is an extra-renal purification technique indicated for patients with end-stage kidney disease (ESKD). Although it has many advantages, it also has a number of complications, such as peritoneo-vaginal leakage of dialysate. Cases Reports: Three male patients, aged 70, 50 and 77 respectively, with ESKD were placed on PD. All three patients presented with inadequate drainage and the progressive appearance of bilateral hydrocele, which occurred one year (late leakage), two and four days (early leakage) respectively after the initiation of exchanges. The etiological investigation led to the conclusion of a peritoneo-vaginal leak associated with an inguinal hernia in only one case. The two cases of early leakage were treated by temporary suspension of PD, with a good response in one case and failure in the second, leading to hisdefinitive transfer to hemodialysis (HD);however, the hernia repair enabled immediate resumption of PD in the third patient. Discussion and Conclusion: Peritoneo-vaginal leakage is a rare mechanical complication in PD. The clinical examination plays an essential role in confirming the diagnosis and in the therapeutic decision. If the diagnosis is uncertain, or if there is a clinical need to show the anatomy of the leak, an imaging approach becomes desirable. This complication should not prevent the progression of PD in the management of patients with ESKD.

Diagnosis of childhood tuberculosis (TB) is difficult, especially in resource-limited countries where the number of reported cases of TB-HIV co-infection continues to rise. This co-infection poses a diagnostic and therapeutic problem for caregivers. We report a case of rifampicin-resistant HIV-TB pulmonary coinfection in a 19-month-old infant.

Introduction: The aim of this study was to contribute to improving the quality of GEUR management in the general surgery department and in the maternity ward of the Ignace Deen national hospital, Conakry University Hospital. Methodology: This was a retrospective, descriptive study lasting two years (January 1, 2020 to December 31, 2022), carried out in the general surgery and gyneco-obstetrics departments of the Ignace Deen national hospital, Conakry University Hospital. We included all patients with a ruptured ectopic pregnancy who received surgical treatment during the study period. Results: We collected 13,524 cases of surgical interventions in the two services, among them, we recorded 89 cases or 0.66% GEUR. The average age of the patients was 24.26 years. Brides were the most represented with 80.96% of cases. Women practicing a liberal profession were 51.69% (n = 46) and housewives 26.97% (n = 24). Clinically, amenorrhea was noted in all patients, i.e. 100%, abdominal-pelvic pain in 95.2% (n = 85) of cases, metrorrhagia in 94.08% (n = 84), abdominal-pelvic sensitivity in 97.44% (n = 87) of cases and anemia in 85.39% of cases. The GEUR was ampullary in 69.66% (n = 62) cases. Salpingectomy was performed in 90.72% (n = 81). The surgical outcomes were satisfactory in 98.87% (n = 88) of cases. We recorded one case of surgical site infection. We have not recorded any deaths. The average length of hospitalization was 4 days. Conclusion: GEUR is relatively high in our context. A good understanding of the prognostic factors of GEUR, awareness and family planning could reduce GEUR.
