A decennial cross-sectional review of assisted reproductive technology in a Tertiary Hospital in Southwest Nigeria.

BACKGROUND: The World Health Organization recommends that Assisted Reproductive Technology be complementary to other ethically acceptable solutions to infertility. Whereas fertility centres are increasing in number in urban regions of Africa, published reports of their performance are sparse. We present a 10-year review of assisted reproductive technology performed in a public tertiary centre in Lagos, Nigeria. METHODS: This was a hospital-based, retrospective, cross-sectional review of 604 women, over a 10-year period that had in-vitro fertilization or in-vitro fertilization with intra-cytoplasmic sperm injection at the Institute of Fertility Medicine, Lagos State University Teaching Hospital. Data obtained were expressed in descriptive statistics and Pearson correlation was used to determine the strength of linear relationship between two continuous variables at a significance level of p < 0.05. RESULTS: The mean age of the women was of 37.7 ± 6.2 years and 89.7% had no previous parous experience. About 27.2% of the male partners had normal seminal fluid parameters while 4.6% had azoospermia. Median serum follicle stimulating hormone of the women was 8.1 IU/L and median serum anti-mullerian hormone was 6.3 pmol/L. There was weak positive correlation between age and serum follicle stimulating hormone (r = 0.306, p < 0.001); weak negative correlation between age and serum anti-mullerian hormone (r = -0.48, p < 0.001) and very weak correlation between body mass index and serum follicle stimulating hormone (r = 0.173, p = 0.011). In-vitro fertilization and intra-cytoplasmic sperm injection was the method of fertilization used in 97.4% of the cases and 81.8% of embryos formed were of good quality. Most women (94.5%) had 2 embryos transferred and 89.9% had day-5 embryo transfer done. About 1 in 4 of the women (143/604, 23.7%) had clinical pregnancy and 49.7% of women who got pregnant had delivery of a live baby at term while 11.9% had preterm delivery of a live baby. CONCLUSION: Despite increasing use and success of assisted reproductive technology in south-western Nigeria, there is room for improvement in clinical pregnancy rates and live birth rates post- assisted reproductive technology. Complication rates are desirably low.

Comparison of the diagnostic accuracy of HE4 with CA125 and validation of the ROMA index in differentiating malignant and benign epithelial ovarian tumours among patients in Lagos, Nigeria.

This prospective cross-sectional study compared the diagnostic accuracy of human epididymal protein 4 (HE4) with cancer antigen 125 (CA 125) and validates the risk of malignancy algorithm (ROMA) in differentiating benign from malignant ovarian tumours. The study population included 112 women with an ultrasound diagnosis of an adnexal mass, out of whom 49 women had a diagnosis of ovarian cancer following optimal debulking surgery, and 63 women had a diagnosis of benign ovarian tumour. All diagnosis was confirmed by histopathological analysis. Serum HE4 and CA 125 were assessed preoperatively according to the manufacturer's instructions. CA 125 and HE4 cut-offs were 35 U/mL and 70 pM/L respectively. Serum CA 125 and HE4 were significantly higher in ovarian cancer patients compared to those with benign ovarian tumours (p < 0.001 and p < 0.000, respectively). HE4 had higher sensitivity (77.5% versus 69.4%), specificity (96.8% versus 82.5%), positive predictive value (PPV) (95% versus 75.6%) and negative predictive value (84.7% versus 77.6%) than CA 125. When the two markers were combined with each other in the ROMA index, Specificity and PPV reached 100% each. In the receiver operative characteristics analysis, the area under the curve for CA 125 was 0.679 (95% CI 0.566-0.791, p = 0.001), HE4 was 0.845 (95% CI 0.760-0.930, p = 0.000) and ROMA was 0.902 (95% CI 0.851-0.998, p = 0.000) and this was statistically significant (p < 0.001). Conclusively, HE4 performed better than CA 125 in differentiating benign from malignant ovarian tumours and the combination of the two biomarkers improved the detection of ovarian cancer. In addition, the cut off values corresponding to the highest accuracy for CA 125 and HE4 were 126 U/mL and 42 pM/L respectively in this study. The value for CA 125 is much higher while that of HE4 is much lower than the reference values obtained predominantly from the white population.

World Health Organization Recommendation for Using Uterine Balloon Tamponade to Treat Postpartum Hemorrhage.

The World Health Organization (WHO) recently published a new recommendation on the use of the uterine balloon tamponade for the treatment of postpartum hemorrhage. The recommendation that uterine balloon tamponade should be used only where there is already access to other postpartum hemorrhage treatments (including immediate recourse to surgery) has proved controversial. It is especially problematic for those working in low-level health care facilities in under-resourced settings, where there are already programs that have introduced low-cost uterine balloon tamponade devices for use, even in settings where recourse to surgical interventions is not possible. However, there are now two separate randomized trials that both unexpectedly show unfavorable outcomes in these settings when a condom catheter uterine balloon tamponade device was introduced. Considering the balance of potential benefits and these safety concerns, the WHO postpartum hemorrhage guideline panel therefore recommends that uterine balloon tamponade should be used only in contexts where other supportive postpartum hemorrhage interventions are available if needed.

Parental acceptance of human papillomavirus vaccination for adolescent girls in Lagos, Nigeria.

BACKGROUND AND AIMS: Human papillomavirus (HPV) vaccination is recommended for adolescent girls and would offer a long-term solution to cervical cancer especially in developing countries. However, parental perception and acceptance is a critical success factor. This study examined the degree of parental acceptance of HPV vaccination for adolescent secondary-school girls in Lagos, Nigeria. MATERIALS AND METHODS: A descriptive cross-sectional survey of adolescent girls' parents was undertaken in two urban and two rural secondary schools in Lagos. Univariate and multivariate analysis were carried out using logistic regression to determine correlates of parental acceptance of HPV vaccine. RESULTS: Of the 318 respondents, 45.9% had poor knowledge of cervical cancer and HPV infection, whereas 29.6% had good knowledge. Majority (54.7%) also had poor knowledge of HPV vaccine, whereas 26.7% had good knowledge. Most (72%) would vaccinate their daughters if vaccines were free, whereas only 35.5% would, if not free. Poor knowledge of cervical cancer and HPV infection significantly reduced the likelihood of vaccination even if free (adjusted odds ratio [OR] =0.48; 95% confidence interval [CI] =0.24-0.94; P = 0.0325), whereas good knowledge of HPV vaccines (adjusted OR = 6.11; 95% CI = 1.37-27.34; P = 0.018) and tertiary education in the mother (adjusted OR = 29.17; 95% CI = 3.98-214.08; P = 0.0009) increased the likelihood, if not free. CONCLUSION: HPV vaccination was acceptable to most parents only if offered free. Poor knowledge of cervical cancer, HPV infection, and vaccine may hinder acceptability. It is recommended that HPV vaccination is offered free through the National Programme on Immunization in Nigeria.

Malaria prevention and treatment in pregnancy: survey of current practice among private medical practitioners in Lagos, Nigeria.

We studied the practice of malaria prevention and treatment in pregnancy of 394 private medical practitioners in Lagos State, Nigeria using a self-administered pre-tested structured questionnaire. Only 39 (9.9%) respondents had correct knowledge of the World Health Organization (WHO) strategies. Malaria prophylaxis in pregnancy was offered by 336 (85.3%), but only 98 (24.9%) had correct knowledge of recommended chemoprophylaxis. Of these, 68 (17.3%) had correct knowledge of first trimester treatment, while only 41 (10.4%) had knowledge of second and third trimester treatment. Only 64 (16.2%) of respondents routinely recommended use of insecticide-treated bed nets. The most common anti-malarial drug prescribed for chemoprophylaxis was pyrimethamine (43.7%); chloroquine was the most common anti-malarial prescribed for both first trimester treatment (81.5%) and second and third trimester treatment (55.3%). The study showed that private medical practitioners have poor knowledge of malaria prophylaxis and treatment in pregnancy, and the practice of most do not conform to recommended guidelines.

Caesarean section--an appraisal of some predictive factors in Lagos Nigeria.

BACKGROUND: Several maternity units in the developing world lack facilities for caesarean section and often have to transfer patients in extremis. This case controlled study aimed to appraise predictive factors for caesarean section. METHODS: One hundred and fifty two consecutive women with singleton pregnancies who had caesarean section were studied. The next parturient with normal delivery served as control. Variables such as age, parity, marital status, booking status, past obstetric history, weight, height, infant birth weight were assessed. Data obtained were analysed using SPSS 16.0 Windows package. RESULTS: During the study period, there were 641 deliveries with 257 of them by caesarean section (40.1%).Logistic regression analysis showed that parity, booking status, maternal height; maternal weight, birth weight, previous caesarean section and ante-partum bleeding were significant predictive factors for caesarean section while maternal age was not. CONCLUSIONS: These predictive factors should be considered in antenatal counseling to facilitate acceptance by at risk women and early referral.

Uterine artery ligation for the treatment of fibroids.

OBJECTIVE: To determine the efficacy of bilateral uterine artery ligation in the treatment of symptomatic uterine fibroids. DESIGN: A descriptive study. SETTING: Tertiary care gynecological clinic, Lagos State University Teaching Hospital, Ikeja, Lagos, Nigeria. SAMPLE: Fifty women who had trans-vaginal bilateral uterine artery ligation for the treatment of uterine fibroids between January 2003 and January 2006. METHODS: Pre-operative baseline ultrasonic measurements of uterine and dominant fibroid volumes were carried out and repeated at two, six, and 12 weeks, then three monthly for a period of three years. Severity of menstrual blood loss, changes in pain symptoms and patients' satisfaction were also assessed. MAIN OUTCOME MEASURES: Changes in uterine and fibroid volumes, hemoglobin values, menstrual pain ratings, and patients' satisfaction ratings. RESULTS: The mean fibroid volume, mean uterine volume, and mean menstrual pain rating showed statistically significant reductions at six, 12, and 36 months. The mean hemoglobin level and patients' satisfaction rating showed a statistically significant increase after six, 12, and 36 months. CONCLUSION: Trans-vaginal bilateral uterine artery ligation is a safe and effective method for the treatment of symptomatic uterine fibroids especially in areas where access to high level medical technology is restricted.

Correlates of abortion related maternal mortality at the Lagos State University Teaching Hospital, Ikeja.

This study was carried out to highlight the probable correlates of mortality among patients managed for abortion related complications at the Lagos State University Teaching Hospital, Ikeja. All patients managed for abortion related complications between 1st January 2000 and 31st December 2003 were studied. Certain relevant socio demographic and clinical factors were compared among the survivors and fatalities. There were a total of 338 patients with abortion related complications. 299 survived while 39 died. Being single, nulliparous, of low educational status, presenting late and having major complications were significantly associated with mortality in this series. Encouragement of safe sex practices, increasing adolescents' access to contraception, additional training of physicians and other appropriate heath workers in abortion care as well as the liberalisation of the restrictive abortion laws in Nigeria will go a long way in reducing abortion related mortality.
