Efficacy of visual inspection of the cervix using acetic acid in cervical cancer screening: A comparison with cervical cytology

Summary Screening programmes for the early detection of premalignant lesions of the cervix are expensive and technically difficult, especially in resource-challenged settings. There is a need for cheaper and equally effective alternative screening methods. This study compared the efficacy of visual inspection of the cervix using acetic acid (VIA) with the Pap smear method. A total of 186 subjects had a Pap smear followed by visual inspection of the cervix using 3 – 5% acetic acid with biopsies taken from suspicious acetowhite positive lesions. Cases of abnormal cytology were recalled for biopsies. A total of 150 subjects were negative for both tests; 30 (16.2%) were positive for VIA, while six were positive for both VIA and Pap smear. VIA detected one lesion missed by Pap smear on biopsy. The sensitivity of VIA was 100%, while that of Pap smear was 85.7%. The negative predictive value of VIA was 100%, while the positive predictive value was 20%. The sensitivity of VIA equals the reported rates for Pap smear. VIA is proposed as a credible alternative to Pap smear in resource-challenged settings.

Factors associated with antenatal mental disorder in West Africa: A cross-sectional survey

BackgroundMaternal mental illness is likely to have a profound impact in less developed parts of the world. A mother experiencing mental illness in a low income setting is at risk of providing sub-optimal care for her offspring which can have grave consequences in an environment where poverty, overcrowding, poor sanitation, malnutrition, tropical diseases and a lack of appropriate medical services may be pronounced. Given the profound consequences of antenatal and postnatal mental illness on maternal mental health, foetal wellbeing and childhood growth and development the factors associated with mental illness in a Sub-Saharan setting merit clarification and investigation.MethodsA prospective survey design was conducted in Lagos. Self reporting questionnaire 20 items - SRQ20 - assessed the presence of mental illness. The WHO Multi-country Study on Womens Health and Domestic Violence Questions assessed womens exposure to violence. Numerous variables potentially associated with mental illness including maternal socio-economic factors, maternal characteristics, obstetric variables and the characteristics of previous children were recorded. Direct logistic regression was performed to assess the impact of a number of variables on the likelihood of presence of mental disorder in the population.Results189 women were surveyed. 7% met the criteria for experiencing a common mental disorder according to their score on the SRQ-20. Of variables examined only the number of female children and the presence of inter personal violence predicted being a case of mental illness (OR = 3.400; 95%CI = 1.374 - 8.414 and OR = 5.676; 95%CI = 1.251 - 25.757 respectively).ConclusionsRates of mental disorder found in our study were lower than those previously observed internationally and in Africa, perhaps reflecting stigma about disclosing symptoms. The predictive nature of violence on mental disorder is in keeping with international evidence. Our study demonstrated that exposure to inter personal violence within the last 12 months and increasing numbers of female children predict the presence of mental illness in a sample of pregnant Nigerian women. Training and education for primary health care and obstetric health workers should highlight these areas.

Caesarean section – an appraisal of some predictive factors in Lagos Nigeria

BackgroundSeveral 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.MethodsOne 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.ResultsDuring 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.ConclusionsThese predictive factors should be considered in antenatal counseling to facilitate acceptance by at risk women and early referral.

Factors associated with acceptability of child adoption as a management option for infertility among women in a developing country

Background Adoption as a treatment option for infertility amongst those that cannot access and/or afford assisted reproduction is not well accepted in developing countries. This study sets out to determine the willingness of infertile women in developing countries to adopt a child and factors that influence women’s attitude to adoption. Methods We conducted a questionnaire survey of consecutive infertile patients who attended the gynecological clinic of a regional teaching hospital over a 2-month period. Information on demographics, fertility history, and attitude to adoption was obtained, and the data were analyzed using SPSS version 16.0. Tests of statistical significance were used where appropriate at the 95% confidence level. Results The majority of respondents were aware of child adoption, and the most common source of information was friends (47.8%), followed by the media (39.7%); 42.6% of respondents were willing to adopt if their infertility became intractable. The main reasons given by those unwilling to adopt were culture (78.3%) and family constraints (13.45%). On univariate analysis of factors associated with a favorable or unfavorable attitude to adoption, awareness of adoption (P = 0.002), duration of infertility > 5 years (P = 0.015), no living child (P = 0.007), tertiary education (P < 0.001), pressure from parents (P = 0.041), household yearly income ≥

Evaluation of blood reservation and use for caesarean sections in a tertiary maternity unit in south western Nigeria

650 (P < 0.001), and belief that treatment will bring about the desired results (P < 0.001) were significant, and all except awareness of adoption turned out to be significant on multiple logistic regression analysis. Conclusion There was a high level of awareness about child adoption among all respondents. However, the acceptability of adoption was significantly lower among poor women and those with limited education. Community advocacy and mobilization, especially through the media as well as via health care providers, will go a long way towards enlightening and enhancing the uptake of adoption among women in Nigeria.

Prenatal ultrasonic diagnosis of conjoint twins

BackgroundHaemorrhage from obstetric causes is the most common cause of maternal mortality in the developing world. Prevention of mortality from haemorrhage will necessarily involve prompt blood transfusions among other life saving measures. There are however limited stocks of fresh or stored blood in many health care facilities in Sub Saharan Africa. Caesarean section has been identified as a common indication for blood transfusion in obstetrics practice and its performance is often delayed by non availability of blood in our centre. An evaluation of blood reservation and use at caesarean sections in a tertiary maternity unit in Lagos, south western Nigeria should therefore assist in formulating the most rational blood transfusion policies.MethodsCase records of 327 patients who had elective and emergency caesarian sections at the Lagos State University Teaching Hospital between 1st October and 31st December 2007 were reviewed. Data pertaining to age, parity, booking status, type and indication for Caesarean section, pre- and post-operative packed cell volume, blood loss at surgery, units of blood reserved in the blood bank, unit(s) of blood transfused and duration of hospital stay was extracted and the data analysed.ResultsThere were 1056 deliveries out of which 327 (31%) were by Caesarean section. During the study period, a total of 654 units of blood were reserved in the blood bank and subsequently made available in theatre. Out of this number, only 89 (13.6%) were transfused to 41 patients. Amongst those transfused, twenty-six (54%) were booked and 31 (75.6%) had primary caesarian section. About 81% of those transfused had emergency caesarean section. The most common indication for surgery among those transfused were placenta praevia (9 patients with 21 units of blood) and cephalo-pelvic disproportion (8 patients with 13 units).ConclusionEven though a large number of units of blood was reserved and made available in the theatre at the time of operation, majority of the patients operated did not need blood transfusion. Provision of a mini- blood bank within the obstetric unit and careful patient categorization will ensure timely availability of blood for surgery without necessarily tying down stock in the central blood bank.

Knowledge of emergency contraception among students in a tertiary institution in a developing country

BACKGROUND A primipara with multiple pregnancy who booked for antenatal care at 21 weeks presented with vaginal bleeding and pedal oedema at the 27th week. She had had five previous ultrasound scans that gave conflicting results. MATERIALS AND METHODS The patient was therefore sent for a confirmatory scan, which was performed using a linear 3.5 MHz transducer of a dynamic imaging dedicated, concept MC ultrasound scan machine. RESULTS A diagnosis of conjoint twins was made. The twin was joined from the mandible to the abdomen. Although they cried at birth, they died a few minutes after. The pregnancy was terminated by caesarian section at the patients request. The patient did well postpartum and was discharged on the 5th postoperative day. Records confirm that this is the first case seen in this hospital, which has been in existence for 18 years. CONCLUSION To diagnose conjoint twins by ultrasound, one needs the expertise and careful scanning techniques, as the diagnosis may be easily missed, especially if the union is extensive.

Gestational age at antenatal booking In lagos, south-west nigeria

Background: Emergency contraception (EC) has been available in developing countries without prescription for some time. There is however little research into the extent of the knowledge of mode of action effectiveness and availability of this form of contraception in rural areas. Objectives: To assess the knowledge of EC with respect to mode of action effectiveness and availability in rural areas among students in a tertiary institution in a developing country. Methods: A questionnaire was distributed to tertiary students in a university in rural area in a developing country. This questionnaire asked about their knowledge of the mode of action of EC its availability over the counter its cost and the students willingness to purchase it. Results: Some 488 of the 500 questionnaires were returned. One hundred and eight (22.1%) of the students had used EC or bought it for a girlfriend at some stage in the past. Two hundred and forty four (50.0%) knew the correct timeframe for its use while 201 (41.2%) were not aware of its availability over the counter in pharmacies and 150 (30.7%) felt unable to purchase EC in a pharmacy where they are known. One hundred (20.5%) of the participants were aware of the cost of EC. Conclusion: The students had good knowledge of the timeframe for the use of EC but lacked information regarding the availability and the cost of EC in the community.
