Maternal mortality in Cameroon: a university teaching hospital report

More than 550,000 women die yearly from pregnancy-related causes. Fifty percent (50%) of the world estimate of maternal deaths occur in sub-Saharan Africa alone. There is insufficient information on the risk factors of maternal mortality in Cameroon. This study aimed at establishing causes and risk factors of maternal mortality. This was a case-control study from 1st January, 2006 to 31st December, 2010 after National Ethical Committee Approval. Cases were maternal deaths; controls were women who delivered normally. Maternal deaths were obtained from the delivery room registers and in-patient registers. Controls for each case were two normal deliveries following identified maternal deaths on the same day. Variables considered were socio-demographic and reproductive health characteristics. Epi Info 3.5.1 was used for analysis. The mean MMR was 287.5/100,000 live births. Causes of deaths were: postpartum hemorrhage (229.2%), unsafe abortion (25%), ectopic pregnancy (12.5%), hypertension in pregnancy (8.3%), malaria (8.3%), anemia (8.3%), heart disease (4.2%), and pneumonia (4.2%), and placenta praevia (4.2%).Ages ranged from 18 to 41 years, with a mean of 27.7 ± 5.14 years. Lack of antenatal care was a risk factor for maternal death (OR=78.33; CI: (8.66- 1802.51)). The mean MMR from 2006 to 2010 was 287.5/100,000 live births. Most of the causes of maternal deaths were preventable. Lack of antenatal care was a risk factor for maternal mortality.

Adherence to antiretroviral therapy assessed by drug level monitoring and self-report in cameroon

OBJECTIVES: To compare adherence to antiretroviral therapy using drug level monitoring and self-report and to explore the relation between these 2 methods and viral load measurements. METHODS: Sixty patients received a fixed-dose combination of nevirapine, stavudine, and lamivudine in a clinical study in Cameroon. Adherence was assessed every 6 months until month 36 by nevirapine minimal plasma concentration and self-report. Plasma HIV-1 viral load was determined at the same time. Analyses included 159 complete observations. RESULTS: The proportion of patients labeled as "adherent" was significantly lower using nevirapine monitoring (88.7%, 95% confidence interval [CI]: 82.7 to 93.2) than self-report (97.5%, CI: 93.7 to 99.3; P = 0.002). Virologic failure was associated with the nevirapine concentration (adjusted odds ratio [aOR] = 4.43; P = 0.018) but not with the self-reported adherence (aOR = 0.84; P = 0.9). As compared with the virologic outcome, the sensitivity of nevirapine level monitoring for predicting inadequate adherence was 20.5%, the specificity was 91.7%, the positive predictive value was 44.4%, and the negative predictive value was 78.0%. For self-report, the respective values were 2.6%, 97.5%, 25.0%, and 75.5%. CONCLUSIONS: Drug level monitoring provided a more reliable estimate of adherence than self-report. This method could be used in research settings. Operational research is required to define how to improve the accuracy of the self-report method because it is the most feasible method in clinical practice

The pattern of non-obstetric fistula: A Cameroonian experience

Objective: To investigate the pattern of Non-obstetrical genital fistula (NOGF) in Cameroonian context. Materials and methods: This was a cross-sectional analytic study, with two groups of patients, including those treated for non-obstetrical fistula as subject, and their obstetrical counterparts as the control. Data were retrieved from the obstetric fistula database of the Department of Obstetrics and Gynecology in the University Teaching Hospital of Yaoundé Cameroon for patients operated from January, 1, 2009 to December 31, 2012. Results: NOGF represented 19.78% of genital fistula. Uro-genital fistula (UGF) represented 72.20% while non-obstetrical genito-digestive fistula (GDF) represented 27.80% of NOGF. The main cause of UGF was hysterectomy (46.15%) while the main cause of genito-digestive fistula was vaginal infections (40.00%). Most patients had never been operated before their arrival in the YUTH (84.60% for UGF and 60.00% for GDF). We had one failure at first surgical attempt. Conclusion: UGF fistula is the main type of NOGF in Cameroonian context, with hysterectomy being the leading cause. Proper knowledge on NOGF will enable better strategies to fight against genital fistula
