Introduction Difficulties in accessing the screening test for viral hepatitis B in maternity wards could be a factor in underestimating the prevalence of anti-HBV antibodies. The rapid diagnostic orientation test (RDOT) could improve seroprevalence and obstetrical prognosis. The aim of this study was to use the rapid diagnostic orientation test (RDOT) to determine the seroprevalence of HBs antigen carriage in pregnant women while highlighting the associated factors. Methods This was a cross-sectional and descriptive study that took place from October to December 2020 (three months) in three (03) reference maternities in western Benin (Mono). Consenting pregnant women received in prenatal consultation had been screened by RDOT. Positive cases were confirmed by ELISA test. The follow-up of these cases made it possible to establish the obstetrical prognosis. Results Of 201 women studied, 11 (5.5%) were positive for RDOT HBV and confirmed by the ELISA test. The factors associated with HBsAg carriage during pregnancy were multiple sexual partnerships (p = 0.01), female circumcision (p = 0.0001), and ignorance of prior HBV serological status (p = 0.0001). No influence of hepatitis B on pregnancy was noted. Conclusion The seroprevalence of hepatitis B in pregnancy was intermediate in the reference maternities of western Benin. The associated factors were multiple sexual partnerships, female circumcision and unawareness of prior HBV status. Free RDOT in maternity wards would improve early detection and management of viral hepatitis B in pregnancy.

Introduction: Despite the many efforts made to combat preventable maternal deaths, these still remain high in Benin. It was therefore important to revisit the causes but especially the adverse events associated with care (EIS) in maternity. Objective: Determine the incidence, adverse events associated with care and causes of intra hospital maternal mortality in cotonou. Methods: This was a cross-sectional maternal mortality review study with retrospective data collection. It covered all cases of maternal death recorded between 2017 and 2021 in two (2) reference university maternities in Cotonou. Adverse events associated with care and the patient were analyzed using the maternal death audit grid validated for Benin. SPSS.26 software was used for data analysis. Results: The in-hospital maternal mortality ratio in Cotonou was 2028 maternal deaths per 100,000 live births in 2021. Only 7.2% (n = 36) of deaths were audited. The deceased mothers were 29.8 ± 7.4 years old, with no fixed monthly income in 82.7% (n = 420). Serious adverse events associated with care were: delay in decision to refer in 37% (n = 188), non-medical referral in 85.8% (n = 436) of cases, inadequate pre-referral treatment in 25.7% of cases. In receiving maternities, delay in diagnosis and inappropriate treatment at the receiving maternity were noted respectively in 22.9% and 28.6% of cases of maternal death. The direct causes of maternal death were dominated by serious obstetric hemorrhage in 43.9% (n = 223). As for the indirect causes, they were dominated by anemia excluding obstetric hemorrhages in 21.5% (n = 109). Conclusion: The in-hospital maternal mortality ratio was very high in Cotonou. The main cause was severe obstetric hemorrhage. There were several serious healthcare-associated adverse events whose correct management would significantly reduce the incidence of maternal deaths.

Introduction: Gynaecological cancers are the deadliest of the women’s cancers in the Republic of Benin. Late diagnosis is the most common reason. Objective: This paper aims to describe the epidemiological characteristics, and clinical and pathological signs of gynaecological cancers treated in the Republic of Benin between 2018 and 2022. Patients and Methods: This was a cross-sectional, descriptive, retrospectively collected study of patient data treated between 2018 and 2022 in two university gynaecology departments in Cotonou. All gynaecological cancers that have histological evidence were included. The epidemiological, clinical and pathological characteristics of the cancers were assessed. Results: Cervical, endometrial and ovarian cancers were the most common in the proportions of 62.0%, 24.1%, 12.0% and 1.8% respectively. The mean age at diagnosis was 54 years. The victims were uneducated and had low economic power in 81% and 85% of cases, respectively. The consultation was late in 82.1% of cases. Metrorrhagia, postmenopausal metrorrhagia and pelvic cluster headache were the common reasons for consultation for cervical, endometrial and ovarian cancer, respectively. Diagnosis was late in 66.7% (n = 71). The most common histological types were squamous cell carcinoma, endometrioid adenocarcinoma, and serous cystadenocarcinoma for cervical, endometrial, and ovarian cancers, respectively. Conclusion: Gynaecological cancers were common and their consultation time was delayed. The diagnosis was made at the advanced stage and there were several reasons for this.

Objective: To analyse the colposcopy results at the Gynaecological Clinic of Houéyiho. Patients and methods: Retrospective, descriptive and analytical studies were conducted by the Clinic of Houeyiho in Cotonou from January 2013 to December 2015. Results: 440 women were received in colposcopy including 251 (57%) referred by health workers for VIA (Visual Inspection with Acétique Acid)/VILI (Visual Inspection with Lugol’s Iodine) abnormalities, forty-seven (47) for abnormal smears (10.7%), thirty-eight (38) for metrorrhagia (8.6%). 10% of cases were mainly concerned with post-therapeutic monitoring (six colposcopies of the vagina fundus after hysterectomy for cervical cancer and four after conization). The average age of patients is 41 years within plus or minus 5 years. Forty (40) cases of Grade 1 Atypical Transformation, twenty-nine (29) cases of Grade 2 Atypical Transformation including two (2) cases of leukoplakia (1 post-conization for CINIII, 1 in a HIV+ patient), ten (10) cases of Grade 1 Atypical Transformation/Grade 2 Atypical Transformation association were recorded. A colposcopy biopsy was performed in 95 patients meaning 21.6% of patients. Five biopsies were realized for a cervical neoplasia suspicion and were sent to Pasteur Cerba laboratory in France for the sake of efficiency and rapidity of results. In Grade 1 Atypical Transformation, 66.6% of CIN1 and condylomata plana were noted. Nevertheless, a case of mucinous adenocarcinoma with metaplasia has been discovered in a TAG1 with a 23-year old patient. In Grade 2 Atypical Transformation, the histology reveals 44.4% of CIN 1, 40.7% of severe dysplasia and 11.1% of carcinomas. Conclusion: The colposcopy may be a good screening method with a good colpo-histology agreement in Cotonou. But it’s relatively expensive (20.000 CFA francs) and the reduced number of colposcopists restricts its use in Benin.

Objective: To evaluate the risk of preterm delivery with vaginal touch in opposition with transvaginal ultrasound in pregnant women who present signs and symptoms of threatened preterm labour. Methods: A prospective study was conducted with descriptive and comparative aims at the University Hospital of Porto-Novo, Benin Republic between 1 March and 31 August 2016. Every pregnant woman admitted to the emergencies of the maternity between 28 and 34 of WA (weeks of amenorrhoea) and attended for preterm delivery risk with intact membranes was included. The risk of preterm delivery was evaluated using vaginal touch and ultrasound examination of cervical length. Results: The risk of preterm delivery was obvious and identical with the cervical dilatation ≥2 cm when the vaginal touch was applied [RR 2.34 IC 95% (1.71 - 3.20)] and ultrasound examination of cervical length - 4.16)]. The cervix obliteration was not statistically linked to preterm delivery. The ultrasound examination of cervical length had a better sensitivity (87.76%) and a negative predictive value (81.54%) against 59.18% and 74.68% respectively for cervical dilatation at vaginal touch. Bishop score also had a better specificity with the one of the ultrasound examination of cervical length (79.11% vs. 33.54%) whereas both of them had almost identical negative predictive value (81.17% vs. 81.54%). Conclusion: Vaginal touch was also as relevant as transvaginal ultrasound while evaluating the risk of preterm delivery. For the lack of ultrasound in emergency rooms, a good physical examination would be sufficient by its own to decide of an adequate management when there is a threat of preterm delivery.

Randomized Trial Comparing Cyclophosphamide, Methotrexate, and 5-Fluorouracil (CMF) Regimen with Rotational CMFEV Regimen (E=Epirubicin, V=Vincristine) as Adjuvant Chemotherapy in Moderate Risk Operable Breast Carcinoma

引用

Journal of Cancer Therapy 2011年第3期2卷 342-353页

作者： Giorgio Cocconi Corrado Boni Maurizio tonato Rodolfo Passalacqua Mariantonietta Colozza Anna M.

Objectives: The CMFEV (cyclophosphamide, methotrexate, 5-fluorouracil, epirubicin, vincristine) regimen is an innovative schedule, designed by our Group, aimed at administering five partially or totally no cross-resistant cytotoxic agents in breast carcinoma. It was randomly compared to CMF (cyclophosphamide, methotrexate, 5-fluorouracil) as primary treatment in operable disease and demonstrated a short-term significant increase in clinical complete response rate and a long-term significant locoregional relapse-free survival in premenopausal patients. So, it seemed worth comparing this regimen with CMF as adjuvant chemotherapy in moderate risk operable breast carcinoma. Methods: Four hundred and eighty-nine patients with stage I or II moderate risk breast carcinoma were randomized to receive CMF or CMFEV regimen for 6 cycles after surgery. Main end points were overall survival (OS), invasive disease-free survival (IDFS) and recurrence-free interval (RFI), as estimated by Kaplan-Meier analyses and log-rank tests. Results: At a median observation time of 7.3 years (range 5.4 months-10.3 years), no significant differences in OS and IDFS were observed between the two arms. Deaths from breast carcinoma were more frequent with CMF (58.5%) than with CMFEV regimen (41.7%) as well as recurrences from breast carcinoma (58.8% with CMF and 41.2% with CMFEV). These differences were not statistically significant. Conclusion: CMFEV appears more effective than CMF in preventing recurrences from primary disease in patients with moderate risk stage I-II breast carcinoma. The lack of statistical significance of the observed differences was probably due to the limited number of patients enrolled which rendered the study underpowdered.
