Triple Gestations in Two University Teaching Hospitals in Yaounde, Cameroon

The frequency of triplet pregnancies is increasing due to medically assisted reproduction. This retrospective study, carried out in 2 university hospitals in Yaounde (Cameroon) over a 6-year period, was done to evaluate the complications that occurred during triple pregnancies as well as the mode of delivery of triplets. A total of 43 cases were analyzed. The most common complications that occurred during pregnancy were preterm delivery and pre-eclampsia. Twenty seven women (62.8%) delivered vaginally and 16 (37.2%) were delivered by caesarean section with the most common indications being mal presentation and cord prolapse of the 1st triplet. In patients who have proper antepartum monitoring, it is possible to pre-select cases for trial of vaginal delivery because vaginal delivery is possible and carries no significant risk for the foetuses.Keywords triplet gestations; pre-eclampsia; premature delivery; vaginal delivery; caesarean sectio

Study of Perineal Tears During Delivery of Singletons in Cephalic Presentation

Background: Perineal lacerations are associated with short and long term maternal complications likeperineal pain and superficial dyspareunia and must be prevented.Aims: To look for risk factors in order to prevent themMethods: This retrospective study was conducted from the 1<sup>st</sup> of January to the 31<sup>st</sup> of December 2007in the maternity of the University Teaching Hospital Yaoundé (Cameroon). All cases of perineal tear that occurred during delivery of singletons in cephalic presentation were recruited. Our data were analysed using SPSS 12.0. The Student's t-test and the Fisher's exact test were used for comparison. The level of significance was 0.05.Results: The incidence of perineal tear was 13.5% (230/1695). Second degree perineal tears represented rd th 22.1% and 3 degree 01.3% of cases. No 4 degree perineal tear was observed. Risk factors for seconddegree perineal tears were nulliparity especially if maternal age was 27 and above, foetal weight = 3500 rd g, instrumental deliveries and deliveries of adolescents while that of 3 degree were forceps delivery (1case) and macrosomic babies (2) in patients of 27 and 29 years.Conclusion: In the above mentioned conditions, the perineum must be well protected and a mediolateral episiotomy must be done to prevent severe perineal tears if many risk factors are present.Keywords: Singletons in cephalic presentation- Perineal tears-Risk factors

The Risk of Adverse Maternal and Neonatal Outcomes in Cameroonian Primiparous Women Aged More Than 26 Years

Primiparas with advanced age are predisposed to adverse maternal and neonatal risks. The aim of this retrospective cohort study, conducted between January 1st and December 31st, 2004 in the maternity of the Yaounde University Teaching Hospital, Cameroon, was to identify from what age these adverse risks become significant in Cameroonian women. The medical files of 233 primiparae aged 26 and above (case) and that of 404 primiparae aged between 20 and 25 years (control) were reviewed and some data compared. Cesarean sections, instrumental deliveries, low Apgar scores at 5th minute and early neonatal death rates were significantly higher in primiparae aged 27 years and above. Hence, Cameroonian women should be enlightened about the risks of delaying first delivery. Furthermore, first pregnancies to be carried at term and first deliveries in women aged 27 and above shall be considered at high risk and consequently well followed.Keywords primiparas aged more than 26 years; soft tissue dystocia; increased cesarean section risk; poor neonatal outcom

Rupture of a previously scarred uterus during second trimester misoprostol-induced labour for a missed abortion: A case report

Misoprostol is useful in ripening the cervix prior to mid-trimester termination of pregnancy. It is particularly indicated in cases of missed abortions whether the uterus is scarred or not. The procedure is safe in the majority of cases. We present a case of uterine rupture during induction of labour with vaginal misoprostol for a missed abortion at 23 weeks gestation in a woman with one previous lower segment caesarean scar. We decided to present this case in order to alert practitioners that although the practice is safe in the majority of cases, there are risks of uterine rupture.

A survey of knowledge, attitudes and practice of emergency contraception among university students in Cameroon

<p>Abstract</p> <p>Background</p> <p>Unsafe abortion is a major public health problem in low-and-middle income countries. Young and unmarried women constitute a high risk group for unsafe abortions. It has been estimated that widespread use of emergency contraception may significantly reduce the number of abortion-related morbidity and mortality. The purpose of this study was to evaluate the knowledge, attitudes and experiences on emergency contraceptive pills by the university students in Cameroon in order to develop and refine a national health programme for reducing unwanted pregnancies and their associated morbidity and mortality.</p> <p>Methods</p> <p>A convenient sample of 700 students of the University of Buea (Cameroon) was selected for the study. Data was collected by a self-administered, anonymous and pre-tested questionnaire.</p> <p>Results</p> <p>The response rate was 94.9% (664/700). General level of awareness of emergency contraceptive pills was 63.0% (418/664). However, knowledge of the general features of emergency contraceptive pills was low and misinformation was high among these students. Knowledge differed according to the source of information: informal source was associated with misinformation, while medical and informational sources were associated with better knowledge. Although the students generally had positive attitudes regarding emergency contraceptive pills, up to 65.0% (465/664) believed that emergency contraceptive pills were unsafe. Those with adequate knowledge generally showed favourable attitudes with regards to emergency contraceptive pills (Mann-Whitney U = 2592.5, p = 0.000). Forty-nine students (7.4%) had used emergency contraceptive pills themselves or had a partner who had used them.</p> <p>Conclusion</p> <p>Awareness of emergency contraception pills by Cameroonian students is low and the method is still underused. Strategies to promote use of emergency contraception should be focused on spreading accurate information through medical and informational sources, which have been found to be reliable and associated with good knowledge on emergency contraceptive pills.</p

Diversity, composition, altitude, and seasonality of high-altitude windborne migrating mosquitoes in the Sahel: Implications for disease transmission

Recent studies have reported Anopheles mosquitoes captured at high-altitude (40–290 m above ground) in the Sahel. Here, we describe this migration modality across genera and species of African Culicidae and examine its implications for disease transmission and control. As well as Anopheles, six other genera—Culex, Aedes, Mansonia, Mimomyia, Lutzia, and Eretmapodites comprised 90% of the 2,340 mosquitoes captured at altitude. Of the 50 molecularly confirmed species (N = 2,107), 33 species represented by multiple specimens were conservatively considered high-altitude windborne migrants, suggesting it is a common migration modality in mosquitoes (31–47% of the known species in Mali), and especially in Culex (45−59%). Overall species abundance varied between 2 and 710 specimens/species (in Ae. vittatus and Cx. perexiguus, respectively). At altitude, females outnumbered males 6:1, and 93% of the females have taken at least one blood meal on a vertebrate host prior to their departure. Most taxa were more common at higher sampling altitudes, indicating that total abundance and diversity are underestimated. High-altitude flight activity was concentrated between June and November coinciding with availability of surface waters and peak disease transmission by mosquitoes. These hallmarks of windborne mosquito migration bolster their role as carriers of mosquito-borne pathogens (MBPs). Screening 921 mosquitoes using pan-Plasmodium assays revealed that thoracic infection rate in these high-altitude migrants was 2.4%, providing a proof of concept that vertebrate pathogens are transported by windborne mosquitoes at altitude. Fourteen of the 33 windborne mosquito species had been reported as vectors to 25 MBPs in West Africa, which represent 32% of the MBPs known in that region and include those that inflict the heaviest burden on human and animal health, such as malaria, yellow fever, dengue, and Rift Valley fever. We highlight five arboviruses that are most likely affected by windborne mosquitoes in West Africa: Rift Valley fever, O'nyong'nyong, Ngari, Pangola, and Ndumu. We conclude that the study of windborne spread of diseases by migrating insects and the development of surveillance to map the sources, routes, and destinations of vectors and pathogens is key to understand, predict, and mitigate existing and new threats of public health

Wealth and sexual behaviour among men in Cameroon

BACKGROUND: The 2004 Demographic and Health Survey (DHS) in Cameroon revealed a higher prevalence of HIV in richest and most educated people than their poorest and least educated compatriots. It is not certain whether the higher prevalence results partly or wholly from wealthier people adopting more unsafe sexual behaviours, surviving longer due to greater access to treatment and care, or being exposed to unsafe injections or other HIV risk factors. As unsafe sex is currently believed to be the main driver of the HIV epidemic in sub-Saharan Africa, we designed this study to examine the association between wealth and sexual behaviour in Cameroon. METHODS: We analysed data from 4409 sexually active men aged 15–59 years who participated in the Cameroon DHS using logistic regression models, and have reported odds ratios (OR) with confidence intervals (CI). RESULTS: When we controlled for the potential confounding effects of marital status, place of residence, religion and age, men in the richest third of the population were less likely to have used a condom in the last sex with a non-spousal non-cohabiting partner (OR 0.43, 95% CI 0.32–0.56) and more likely to have had at least two concurrent sex partners in the last 12 months (OR 1.38, 95% CI 1.12–1.19) and more than five lifetime sex partners (OR 1.97, 95% CI 1.60–2.43). However, there was no difference between the richest and poorest men in the purchase of sexual services. Regarding education, men with secondary or higher education were less likely to have used a condom in the last sex with a non-spousal non-cohabiting partner (OR 0.24, 95% CI 0.16–0.38) and more likely to have started sexual activity at age 17 years or less (OR 2.73, 95% CI 2.10–3.56) and had more than five lifetime sexual partners (OR 2.59, 95% CI 2.02–3.31). There was no significant association between education and multiple concurrent sexual partnerships in the last 12 months or purchase of sexual services. CONCLUSION: Wealthy men in Cameroon are more likely to start sexual activity early and have both multiple concurrent and lifetime sex partners, and are less likely to (consistently) use a condom in sex with a non-spousal non-cohabiting partner. These unsafe sexual behaviours may explain the higher HIV prevalence among wealthier men in the country. While these findings do not suggest a redirection of HIV prevention efforts from the poor to the wealthy, they do call for efforts to ensure that HIV prevention messages get across all strata of society

The Uptake of Integrated Perinatal Prevention of Mother-to-Child HIV Transmission Programs in Low- and Middle-Income Countries: A Systematic Review

BACKGROUND: The objective of this review was to assess the uptake of WHO recommended integrated perinatal prevention of mother-to-child transmission (PMTCT) of HIV interventions in low- and middle-income countries. METHODS AND FINDINGS: We searched 21 databases for observational studies presenting uptake of integrated PMTCT programs in low- and middle-income countries. Forty-one studies on programs implemented between 1997 and 2006, met inclusion criteria. The proportion of women attending antenatal care who were counseled and who were tested was high; 96% (range 30-100%) and 81% (range 26-100%), respectively. However, the overall median proportion of HIV positive women provided with antiretroviral prophylaxis in antenatal care and attending labor ward was 55% (range 22-99%) and 60% (range 19-100%), respectively. The proportion of women with unknown HIV status, tested for HIV at labor ward was 70%. Overall, 79% (range 44-100%) of infants were tested for HIV and 11% (range 3-18%) of them were HIV positive. We designed two PMTCT cascades using studies with outcomes for all perinatal PMTCT interventions which showed that an estimated 22% of all HIV positive women attending antenatal care and 11% of all HIV positive women delivering at labor ward were not notified about their HIV status and did not participate in PMTCT program. Only 17% of HIV positive antenatal care attendees and their infants are known to have taken antiretroviral prophylaxis. CONCLUSION: The existing evidence provides information only about the initial PMTCT programs which were based on the old WHO PMTCT guidelines. The uptake of counseling and HIV testing among pregnant women attending antenatal care was high, but their retention in PMTCT programs was low. The majority of women in the included studies did not receive ARV prophylaxis in antenatal care; nor did they attend labor ward. More studies evaluating the uptake in current PMTCT programs are urgently needed
