Background: Adolescent pregnancy is a serious health and social problem worldwide as well as in Cameroon. The aim of this study was to determine the obstetrical and perinatal outcomes of nulliparous adolescent pregnancies in a reference hospital in Cameroon. Methods: A retrospective cohort study to compare the outcomes of nulliparous adolescent pregnancies to those of nulliparous women aged 20 to 25 years was carried out at the Yaoundé General Hospital between January 1993 and December 2012. Results: Adolescent deliveries represented 2.84% (331 deliveries) of all deliveries registered during the study period. The adolescent mothers had a significantly higher incidence of preeclampsia/eclampsia, preterm delivery and low birth weight babies (<2500 g) when compared to the control group (OR, 3.46;CI 95%, 1.46 - 8.18;OR, 1.94 CI 95%, 1.34 - 2.79;OR, 1.98, CI 95%, 1.39 - 2.46, respectively). However, placenta previa, abruptio placenta, episiotomy, cesarean section, vaginal instrumental delivery, perineal tears and post partum hemorrhage were not significantly different in the two groups. Furthermore, there was no statistically significant difference between the two groups regarding fetal distress, low Apgar score (st and 5th minutes), the rate of admission in the neonatal intensive care unit, stillbirth and neonatal death. Conclusion: Adolescent pregnancy is associated with an increased risk of preeclampsia/ eclampsia, preterm birth and low birth weight.

Objective: The aim of this study was to determine maternal and perinatal complications of pregnancies complicated by severe preeclampsia in three tertiary care centers in Cameroon. Methods: We carried out a descriptive cross sectional study from the 1st of June 2012 to the 31th of June 2014, among pregnant women with severe preeclampsia followed up in three tertiary level hospitals in Yaoundé, Cameroon: the Yaoundé General Hospital, the Yaoundé Central Hospital, and the Yaoundé University Hospital. Statistical analysis was performed using EPI 3.5.5. Data were described as means ± standard deviation, percentages and numbers. Chi-square and Fisher exact tests were used where appropriate. Results: Of the 2500 deliveries registered during the study period, 111 cases (8.49%) were managed as severe preeclampsia. Four patients refused to participate and were excluded from the study. Most of these patients were non workers (58.0%), pauciparous (61.7%) and young (median age of 27.47 years ± 6.46). Eclampsia (12.14%), abruptio placentae (11.21%) and hypertensive retinopathy (7.47%) were the most frequent maternal complications. Two cases (1.86%) of maternal deaths occurred in patients who had eclampsia. Prematurity (48.6%), intra uterine fetal death (13.1%) and oligoamnios (11.2%) were the most frequent fetal complications. All four neonatal deaths occurred in women in whom the diagnosis of severe preeclampsia was done between 28 and 33 weeks of gestation. Conclusion: Pregnancies complicated by severe preeclampsia had significantly high maternal and perinatal morbidity and mortality in Cameroon. The complications of severe preeclampsia can be prevented by more widespread use of antenatal care, education of primary medical care personnel, prompt diagnosis of high-risk patients and timely referral to tertiary medical centers.

In Cameroon, induced abortion is permitted when a woman’s life is at risk, to preserve her physical and mental health and on the grounds of rape or incest. Objectives: The aim of this study was to determine the prevalence, reasons and complications of voluntary induced abortion among women attending the obstetrics and gynecology services in an urban area, Yaoundé and in a rural area, Wum in Cameroon. Methods: We carried out a cross sectional study, with 509 women recruited between August 1, 2011 and December 31, 2011 in three health facilities in Cameroon. We appreciated the frequency, complications and reasons for Voluntary induced abortions. Results: The prevalence of voluntary induced abortion was 26.3% (134/509) globally;25.6% (65/254) in urban area and 27.1% (69/255) in rural area. One hundred and eleven (83%) cases of induced abortions were carried out in a health structure and 23 (17%) cases in private homes. Medical doctors and nurses were the most frequent abortion providers in both urban (84.7%) as well as rural setting (77.2%). The three main reasons for induced abortion were to pursue their studies (34.3%), not yet married (22.6%) and fear of parents (13.9%). Complications were reported by 20% (27/134) of respondents who had carried out voluntary induced abortion. Excessive bleeding was the most reported complication (70.4%). Conclusion: Despite its illegality in Cameroon, the prevalence of voluntary induced abortion was high in this study.

International Journal of Clinical Medicine 2015年第12期6卷 934-939页

作者： jean dupont kemfang Ngowa jean Marie Kasia Victorine Nkongo Anny Ngassam Jovanny Fouogue Tsuala Philemon Nsem Alexis Medou Department of Obstetrics and Gynaecology Faculty of Medicine and Biomedical Sciences University of Yaoundé I Yaoundé Cameroon Gynecological Endoscopic Surgery and Human Reproductive Teaching Hospital Yaoundé Cameroon Anesthesia Unit Yaoundé General Hospital Yaoundé Cameroon

Background: Infertility is a global problem, but the highest prevalence is in low resource countries, particularly in sub-Saharan Africa where tubal damage following pelvic infection is the commonest cause. Objectives: This study aimed to assess contribution of laparoscopy as a diagnostic and therapeutic tool in infertile women in our setting. Methods: A descriptive review of complete medical records of 208 women who underwent laparoscopy at the Gynaecology Unit of Yaoundé General Hospital from December 2007 to December 2012. Results: Two hundred and eight women were enrolled in this study. Mean age was 32.6 ± 11.25 years. Infertility was secondary in 71.6% of cases;125 (60.1%) women were married and 116 (55.8%) had a positive serology of Chlamydia trachomatis infection. The most frequent findings during diagnostic laparoscopy were: pelvic adhesions (83.7%), hydrosalpinx (21.6%), pyosalpinx (4.8%), perihepatic adhesions (25.5%), uterine fibromas (22.6%), pelvic endometriosis (13%) and ovarian abnormalities (10.1%). The surgical procedures during laparoscopy were: adhesiolysis (79.7%), tuboplasty (35.0%), salpingectomy (8.2%), ovarian cystectomy (5.8%) and myomectomy (1.9%). Three (1.4%) cases of uterine perforation and 1 (0.5%) case of laparoscopy conversion to laparotomy were observed. Conclusion: Diagnostic laparoscopy revealed that tubal lesions and pelvic adhesions were still the major causes of female infertility in developing countries. Adhesiolysis and tuboplasty were the most frequently performed surgical procedures during laparoscopy. Therefore, training in endoscopic surgery should be regarded as an important issue in developing countries.

Background: Cervical cancer is the third most common cancer worldwide, and 80% of cases occur in the developing world. A critical component of effective cervical cancer screening programs is the ability to offer women appropriate and effective treatment for cervical intra epithelial neoplasia (CIN). Objectives: This study aimed at assessing the primary experience of management of CIN by Loop Electrosurgical Excision Procedure (LEEP) in a low resource country. Methods: We carried out a descriptive cross sectional study at the Yaoundé General Hospital in Cameroon. Results: Twenty three cases of CIN were treated by LEEP. Mean age of patients was 40.5 ± 9.9 years. Six (26.1%) patients were infected by the Human Immunodeficiency Virus (HIV). LEEP was indicated in 21 (91.30%) cases for CIN2 and CIN3. The mean duration of the surgical procedure was 10 ± 3 minutes. There was one (4.3%) complication (persistent cervical bleeding). Surgical margins were negative for dysplasia or invasive carcinoma in 18 (78.26%) cases and non-applicable in 5 (21.73%) cases (thermal artefacts of margins and cervicitis without CIN). One patient with micro invasive carcinoma on post-operative histology was treated by total hysterectomy. Cervical cytology was normal at 6 months post LEEP for 15 cases out of 16 (93.8%) patients who performed the test. One woman achieved pregnancy and delivered a term baby. Conclusion: Treatment of CIN by LEEP is feasible, safe and effective in our setting.

This study aimed to estimate the survival rate of breast cancer in a group of patients followed up at the Yaoundé General Hospital in Cameroon. A retrospective review of records of patients managed for breast cancer between 1995 and 2007 was carried out at the Yaoundé General Hospital. Survival analysis was carried out with survival defined as the time between the date of unequivocal diagnosis of cancer and the date of last follow-up or death. Survival curves were plotted in R.3.1.1 software. Mean age of the patients was 47.5 ± 12.36 years. Most of the patients (67.9%) presented with advanced breast cancer disease (stage III and IV). Overall patient survival rate was 30% at 5 years and 13.2% at 10 years. Median overall survival time was 2 (1.9 - 3) years. There was a correlation between survival and the stage of disease. The highest survival rates were recorded in stages I and II while the lowest rates were recorded in stage IV. There was no statistically significant difference in survival among the age groups (p = 0.15). Overall survival rates of breast cancer are 30% at 5 years and 13.2% at 10 years among Cameroonian patients and are lower compared with 90% and 82% respectively at 5 years and 10 years in some developed countries.

Background: Polycystic ovary syndrome (PCOS), characterized by ovulatory dysfunction, polycystic ovary(PCO),hyperandrogenism and insulin resistance is the commonest endocrine disorder in women of reproductive age. It is an intriguing pathology that involves the perpetuation of a vicious circle with reproductive, endocrine and metabolic components. We aimed to assess the reproductive features and insulin sensitivity (IS) in infertile women with or without PCOS. Materials and Methods: We carried out a cross-sectional analytic study at the outpatient Obstetrics and Gynaecology Department of the Yaounde Gyneco-obstetric and Pediatrics Hospital, Cameroon from September 1st 2012 to March 31st 2013 giving total study duration of 07 months. Laboratory analyses were carried out at the National Obesity Centre(NOC)of the Yaounde Central Hospital, Cameroon. Results: Overall, 36 infertile females were enrolled, which included 15 diagnosed cases of PCOS according to Rotterdam consensus meeting of 2003 and 21 non PCOS subjects as control. PCOS women were younger than non PCOS women (28.8 ± 5.5 vs. 35.0 ± 4.2 years;p = 0.0004). The majority of the women in the PCOS group were spaniomenorrheic (11/15), and ultrasonographic findings were typical of PCOS. Hirsutism score was higher in the PCOS group with a median of 9 (7 - 13). Insulin sensitivity was impaired in two-thirds of the study population, with 12 women found to be insulin resistant(6 PCOS, 6 non PCOS), 12 patients had intermediate insulin sensitivity(2 PCOS, 10 non PCOS)and 12 insulin sensitive(7 PCOS, 5 non PCOS). Apart from blood glucose levels (p = 0.007), all other anthropometric and biological parameters were not significant. Spearman’s correlation identified fasting plasma glucose and total cholesterol as factors associated with insulin sensitivity in females with PCOS. Impaired fasting glucose was observed in 13 patients with 08 from the PCOS group. Conclusion: We conclude that young age, spaniomenorrhea and hirsutism

Context: In Cameroon, breast cancer (BC) is usually diagnosed late in the disease course. About a third of women affected are aged less than 40 years. Chemotherapy (CT) could alter ovarian function and thereby compromise future fertility in these women. We therefore described the fertility of women following CT for BC in women treated at the Yaounde General Hospital (YGH). Methods: It was a retrospective, descriptive, cross-sectional study conducted over 8 months, from January to August 2017. We used the files of patients managed for BC from January 2011 to December 2015 in the medical oncology unit of the YGH. Results: We included 265 patients for the study following at least one year of CT. The mean age at the onset of CT was 35.9 ± 6.9 years. Most of the patients had fewer than 2 deliveries (68.3%). Intraductal carcinoma was the most frequent histological lesion (90.6%) and most often diagnosed in advanced stages (73.5%). As per CT, the FAC protocol was the most used (44.5%). The menstrual cycles of the patients were more regular prior to the onset of chemotherapy (89.4% vs. 58.9%), while the mean period of resumption of menstrual activity following cessation of chemotherapy was 6.3 ± 2.0 months. Chemotherapy-related amenorrhoea was observed in 29.1% of patients after 12 months of treatment. More than half of these women (51.3%) complained of a drop in libido and 6.4% achieved pregnancy within 13 months following cessation of chemotherapy. Conclusion: Following chemotherapy for BC, menstrual cycle disorders are more frequent and this can affect the patients’ reproductive potential. Fertility consultations should be integrated into the management plan of such patients.

Heart disease in pregnancy is the cause of significant maternal and perinatal morbidity. We wanted to evaluate the maternal and perinatal outcomes of pregnant women with heart disease in Yaoundé, Cameroon. This was a cross sectional study with retrospective data collection of 45 pregnancies in 42 women with heart disease followed at three Yaoundé referral hospitals in Yaoundé, Cameroon from January 1st 2015 to December 31st 2020. We collected data on maternal obstetrical and perinatal outcomes. The frequency of pregnancies with heart diseases was 0.1%. The mean maternal age was 29.05 ± 6.5 years. At first antenatal visit, all patients were in class I (84.4%) and II (15.6%) of the New-York Heart Association (NYHA) functional class. Valvular heart disease (51.1%) was the most common type followed by cardiomyopathy (37.7%). Over half of the deliveries were vaginal (51.1%). A cesarean section was generally indicated for the usual obstetrical reasons (54.5%) and for heart disease (31.8%). Complications included 17 (37.7%) cases of heart failure, 6 (13.3%) cases of pulmonary edema, 2 (04.4%) cases of pulmonary embolism, 3 (06.6%) maternal deaths and 3 (06.3%) perinatal deaths, 14 (29.7%) premature births and 3 cases of (6.3%) intrauterine growth retardation. The maternal deaths were cases complicated by pulmonary edema and all had dilated cardiomyopathy. The maternal and perinatal outcomes of pregnant women with heart disease are marked in our environment by increased

Introduction: Breast cancer is often diagnosed at an advanced stage in Cameroon. The objective was to analyse consultation, diagnosis and treatment delays for breast cancer among patients followed up at the Yaoundé General Hospital (YGH) in Cameroon. Materials and Methods: This was a cross-sectional study carried out from the files of patients followed up for breast cancer at the YGH from January 1, 2014 to April 30, 2018. A total of 183 patients were included. We measured time elapsed between the awareness of first signs of disease and the initial consultation (consultation delays), time lapse between the initial consultation and pathological diagnosis of breast cancer (diagnosis delays), interval between pathological diagnosis and treatment onset (treatment delays), time elapsed between the initial consultation and management (health system delays) and time elapsed from awareness of first signs of disease to treatment onset (overall delays).
