Introduction:?Abnormal uterine bleeding (AUB) is one of the most commonly encountered symptoms in gynecological consultations. The prognosis is rarely endangered but the impact on the quality of life is sometimes important. Objective:?Our objective was to assess the epidemiological profiles of patients consulting for AUB at the Yaounde Gyneco-Obstetrics and Pediatrics Hospital.?Methodology:?We carried out a descriptive cross-sectional study at the Yaounde Gyneco-Obstetrics and Pediatrics Hospital. We included all women with acute or chronic per vaginal bleeding and we excluded all cases of bleeding in pregnancy, bleeding due to infection, pre pubertal bleeding and the incomplete files. Data were?collected from January to May 2019, using a questionnaire, and analyzed using Epi Info version 3.5.4 and SPSS version 7. softwares. Results:?A total of 163 patient files were exploited and analyzed. The frequency of AUB in outpatient gynaecology clinics was 3.7%. AUB patients had a mean age of 36 ± 12.27 years and the most represented age group was 30 to 35 years, with 17.1% cases. Sixty-seven representing 41.1% patients were married, 23.9% were civil servants, 23.1% were tertiary employees, and 40.3% had secondary level of education. Almost 44.1% were nulliparous and 53.9% had unknown HIV status an 83.4% have never used contraception. Conclusion:?The frequency of AUB during gynecological consultations is 3.7%. Those women have an average age of 36 years, most of them are nulliparous and have never use contraception.

Background: In Vitro Fertilization/Intracytoplasmic Sperm Injection (IVF/ICSI) represents the final step in the management of Polycystic Ovarian Syndrome (PCOS). Our objective was to study the association between PCOS phenotypes and IVF/ICSI results in women admitted to Gynaecological Endoscopic Surgery and Human Reproductive Teaching Hospital (CHRACERH). Material and Method: We carried out a cohort study with historical-prospective data collection over a period of seven years (January 2016 to March 2023) at Chracerh. PCOS patients were subdivided into 4 subgroups A, B, C and D. Results: We recruited 128 patients including 64 PCOS patients divided into four phenotypes and 64 non-PCOS patients constituting the control group. Phenotype D without hyperandrogenism had used the lowest dose of gonadotropins, i.e. 1939.7 ± 454.3 IU, and had produced a greater quantity of estradiol on the day ovulation was triggered (6529.8 ± 4324.8 ng/ml). The average number of punctured follicles and mature oocytes were higher in the phenotype D group. Ovarian hyperstimulation syndrome (OHSS) occurred mainly in phenotype D (3/35), with an estimated prevalence of 2.3%. The fertilization rate seemed lower in the hyperandrogenic phenotypes A, B, C compared to the group without hyperandrogenism without significant difference (p = 0.461). The biological pregnancy rate and live birth rate were comparable between the different groups. Conclusion: Phenotype D used less dose of gonadotropins. Biological pregnancy and live birth rates were comparable between the different phenotypes.

Introduction: Fibroid benign tumour of the uterus can be operated either by laparotomy or laparoscopy. Laparoscopy is not well vulgarised in our settings. Objective: The main objective was to compare the surgical and post-operative outcomes of laparoscopic versus abdominal myomectomy. Methods: We performed a comparative analytical cross sectional study from 1st January 2016 to 31st March 2018 consisted of two groups: group 1 of women who underwent laparoscopic myomectomy (LM) and group 2 of women who underwent abdominal myomectomy (AM). The data collected was entered in Epi Info 7.2 version and exported to IBM SPSS Statistics version 22 for analysis. We used alpha error margin of 5% and confidence interval of 95%. Results: We enrolled 50 cases of myomectomy consisted of 33 (66.0%) files for AM and 17 (34.0%) files for LM. The clinical presentation of fibroid was similar in both groups. The main operation time (H) was (1.27 ± 0.13) for laparoscopy which is much less than (2.05 ± 0.07) for laparotomy group (p = 0.006). In AM group we had 04 post-operatory complications against zero complications in LM group but the difference was not statistically significant (p = 0.387). In the second look laparoscopy, the types of adhesions were not statistically significant (p = 0.471). Conclusion: Laparoscopic offers advantages compared to abdominal myomectomy.

Introduction: Endometriosis is a chronic disease affecting approximately 10% of women. Our aim was to describe the epidemiological profile, clinical presentation and location of lesions in patients operated on for endometriosis. Methodology: We conducted an analytical cross-sectional study with retrospective data collection over a period of 05 years from 1 January 2017 to 31 March 2022. Our study population consisted of women who had undergone laparoscopy for endometriosis. Data analysis was performed using SPSS software version 23.0. Results: In total we included 159 patients who had undergone laparoscopy for endometriosis. The mean age was 32.9 ± 5.9 years, most of whom were nuligravida 61.6% (n = 99). Infertility was the most frequent reason for consultation, accounting for 72.3% (n = 115), followed by dysmenorrhoea in 60.8% (n = 96) of cases and chronic pelvic pain in 37.7% (n = 60). In addition, 46 (28.9%) patients complained of deep dyspareunia, 17 (10.7%) of dyschezia and nine (5.7%) of dysuria. Magnetic Resonance Imaging (MRI) was used in one patient. Diagnostic laparoscopy was performed directly in 77 (48.4%) patients. The lesions were multifocal, according to the #ENZIAN classification nomenclature. Tubal lesions were most frequently found 107 (67.3%) on the left, followed by compartment B (uterosacral ligaments, cardinal ligaments and lateral pelvic wall) 49.7% (n = 79), and endometriomas 40.9% (n = 65). Conclusion: Women operated on for endometriosis were of a more advanced age, and predominantly nulliparous. Infertility was the most frequent reason for consultation and tubal location most frequently encountered for superficial lesions and compartiment B for deep lesions according to #ENZIA.

This paper is devoted to the study of the subspace of Wm＇＂ of functions that vanish on a part γ0 of the boundary. The author gives a crucial estimate of the Poincare constant in balls centered on the boundary of γ0. Then, the convolution-translation method, a variant of the standard mollifier technique, can be used to prove the density of smooth functions that vanish in a neighborhood of γ0, in this subspace. The result is first proved for m = 1, then generalized to the case where m 〉 1, in any dimension, in the framework of Lipschitz-continuous domain. However, as may be expected, it is needed to make additional assumptions on the boundary of γ0, namely that it is locally the graph of some Lipschitz-continuous function.

After the microbiology based on Pasteur's method and polymerase chain reaction(PCR), the diagnosis company named Dendris has proposed a third-generation of diagnosis enabling the search of a broad range of pathogens with strong sensitivity and specificity. This extraordinary profile was possible thanks to the use of phosphorus dendrimers for which various techniques of deposition on a given support were investigated and described and analyzed in this report.
