Factors associated with breast disorders detected by clinical breast examination during pregnancy and six months postpartum in Ibadan, South-western Nigeria

Background

Breast disorders (BD) during pregnancy and postpartum cause anxiety and reduce women's quality of life. The study examined BD risk factors during pregnancy and six months after delivery.

Methods

Women attending antenatal clinics at 26 weeks gestation were recruited. 1248 pregnant women were followed six months postpartum. During recruitment, a validated questionnaire was used to collect participant characteristics and risk factors. Palpable lumps, inflammation, persistent pain, and abnormal nipple discharge were classified breast disorders. Statistical analysis used multiple logistic and cox regression models at p<0.05.

Results

Women with benign breast disease were more likely to develop BD (aOR = 2.63, 95% CI = 1.50-4.88). One pregnancy increases the risk of BD more than three times (aOR=0.52, 95%CI: 0.29-0.95). History of breast trauma (aHR=3.59, 95%CI: 1.40-9.17) and 3 miscarriages vs. none (aHR=2.23, 95%CI: 1.04-4.23) were also risk factors for BD. The second quartile of physical activity was associated with a lower risk of BD (aHR=0.35, 95%CI: 0.15-0.78).

Conclusion

Women with breast trauma and miscarriage are more likely to develop breast disorders during pregnancy and six months after delivery. Our findings highlight the need for additional longitudinal research to validate these findings and plans for prevention and control.

Perceptions of male partners towards intimate partner violence in the Gambia: A qualitative study

Intimate partner violence (IPV) is a form of Gender-based violence that is a public health problem. The health outcomes of IPV have cascading effects on the family's financial, emotional, sexual, and physical wellbeing. Sub-Saharan Africa carries a significant burden of IPV. In The Gambia, domestic is prevalent, with more than 80% of the women believing that it is justified for a man to beat his wife. Men are the predominant perpetrators of IPV in the Gambia. The study employed a cross-sectional design using a qualitative approach utilizing phenomenology focused on the participants lived experiences. The study was conducted in Basse in the Upper River Region in The Gambia. The study purposefully sampled 26 respondents, all of whom were married. Semi-Structured in-depth interviews were administered to the respondents in Mandinka, Wolof and Serahuli to collect the study data. Both deductive and inductive approaches were used to develop the codebook and themes relevant to the study data. The participants expressed various ideas regarding IPV, with the general perspectives suggesting the causes, effects, and ultimate probable solutions to the phenomenon. The respondents interviewed believed that both women and men bared the responsibility of IPV. Varying connotations were placed on the individual's responsibility towards perpetrating IPV with men seen as physically and financially violent compared to women. Solutions to the IPV problem were seen as both external and internal, with government intervention being offered up as a solution. The overall response in the study indicated that there was a general understanding of IPV and a need to educate both men and women of its dangers to the overall health. The finding of this study shows that further needed on a large scale to understand the dynamics of IPV in The Gambia. This will help in designing sustainable solutions to the IPV problem.

Outcome of urethral reconstruction among vesico-vaginal fistula patients: a cross-sectional study

Background

Obstetric fistula (OF) complicated by urethral loss (UL) poses a challenge to both the fistula surgeon and obstetric fistula patient. The involvement of the urethra and urethral closure mechanism in OF is an important determinant of successful closure of fistula and restoration of urinary continence. OF with UL is often associated with unsuccessful repair outcome. We describe urethral reconstruction in genital tract fistula patients with UL and the outcomes of the repair.

Methods

Aim To review the clinical characteristics and outcome of vesico-vaginal fistula associated urethral loss following urethral reconstruction.

This was a descriptive cross-sectional study conducted at the University College Hospital, Ibadan, Nigeria. A 5-year prospective data of all vesico-vaginal fistula patients with urethral loss (2011–2016) were reviewed and analysed. Data collected include socio-demographic and obstetric characteristics; cause of the fistula; and fistula characteristics—type of fistula, number of previous repairs, urethral loss, outcome of repair and follow-up. Data were entered and analysed using IBM SPSS version 20.

Results

Urethral loss occurred in 23 (15.3%) out of 150 women with OF; these women had urethral reconstruction surgery. The commonest type of urethral loss encountered in this cohort was proximal urethral loss which was seen in 12 (52.2%) patients. The most common types of fistula seen with urethral loss were large vesico-vaginal fistula (34.8%) and mid-vaginal fistula (26.1%). More than half of the women (56.6%) had previous unsuccessful repair at other facilities before presentation. The fistula closure rate was high (82.6%) regardless of type of urethral loss. Among the women with successful closure of OF with UL, about 36.8% had urinary stress incontinence post-fistula repair.

Conclusion

Urethral loss appears to be a rare complication of obstetric fistula. Successful closure with stress incontinence was seen in a sizeable number of women with OF with UL. Preoperative assessment for determinant of post-repair incontinence and surgical repair by experienced surgeons will improve successful outcome of repair in women with obstetric fistula with UL.

Intimate partner violence among pregnant women attending antenatal care services in the rural Gambia

Background

Intimate partner violence (IPV) refers to any behavior by either a current or ex-intimate partner or would-be rejected lover that causes physical, sexual, or psychological harm. It is the most common form of violence in women’s lives. According to a World Health Organization report, about 1 in 3 women worldwide experience at least one form of IPV from an intimate partner at some point in her life. In the Gambia, about 62% of pregnant women experience at least one form of violence from an intimate partner. IPV has severe physical and mental health consequences on a woman ranging from minor bodily injury to death. It also increases the risk of low birth weight, premature delivery, and neonatal death.

Methods

A health facility-based cross-sectional study design was carried out to assess the magnitude and factors associated with intimate partner violence among pregnant women seeking antenatal care in the rural Gambia. The study enrolled 373 pregnant women, and a multi-stage sampling technique was used to select the respondents. An interviewer-administered structured questionnaire was used to obtain information from the study participants. The collected data were analyzed using SPSS Ver.22. Bivariate and multivariate logistic regression were used to determine the association between dependent and independent variables. Odds ratio with 95% confidence interval (CI) was computed to determine the presence and strength of associated factors with IPV.

Result

The study reveals that the prevalence of IPV in The Gambia is 67%, with psychological violence (43%) being the most common form of IPV reported by the respondents. The multivariate logistic regression result reveals that being aged 35 years or older [AOR 5.1(95% CI 1.5–17.8)], the experience of parents quarreling during childhood [AOR 1.7(95% CI 1.0–2.75)], and having cigarette smoking partners [AOR 2.3 (95% CI 1.10–4.6)] were significantly associated with IPV during pregnancy.

Conclusion

This study has demonstrated that all forms of IPV in rural Gambia are frequent. Women older than 35 years, had experienced parents quarreling, had a partner who smoked, and a partner who fight with others were more likely report IPV compared to other pregnant women in the study. We recommend that IPV screening should be included as an integral part of routine antenatal care services in The Gambia. Community-based interventions that include indigenous leaders, religious leaders, and other key stakeholders are crucial to create awareness on all forms of IPV and address the risk factors found to influence the occurrence of IPV in rural Gambia.

Abstract 2320: Evaluating a polygenic risk score for breast cancer in women of African ancestry

Background: A polygenic risk score (PRS) for breast cancer including 313 common variants developed by the Breast Cancer Association Consortium (BCAC) has been demonstrated to identify women who are at high risk of developing breast cancer [odds ratio (OR 95%CI) = 1.61 (1.57-1.65) per SD] in women of European ancestry. In the present study, we examined the performance of the 313-variant PRS and a PRS including 179 variants reaching genome-wide significance in previous genome-wide association studies (GWAS), in women of African ancestry.

Methods: We assembled genotype data for women of African ancestry from 28 breast cancer studies, including a total of 9,241 cases and 10,193 controls. We constructed the 179-variant and 313-variant PRSs with relative risk weights for each variant estimated in women of European ancestry in BCAC. The associations between the two PRSs and overall, ER+ and ER- breast cancer risk were estimated using logistic regression adjusting for age, study site and principal components. Discriminatory accuracy of the PRSs was evaluated using the receiver operating characteristic curve (AUROC). We then recalibrated the 179-variant PRS by replacing index variants with variants in each region that better captured risk in women of African ancestry and used relative risk weights estimated in women of African ancestry. We also assessed PRS performance by age (&lt;55 versus ≥ 55 years).

Results: Both the 179 and 313- variant PRSs were significantly associated with overall, ER+ and ER- breast cancer risk, with odds ratios (OR) per standard deviation of 1.21~1.37 and AUROCs ranging from 0.57 to 0.59. The 179-variant PRS outperformed in ER- cancer [1.31(1.24,1.37) per SD] while the 313-SNP PRS was better for overall [1.27(1.23,1.31) per SD] and ER+ cancer [1.37(1.32,1.43) per SD]. For overall breast cancer, compared to women with average risk (40th-60th PRS percentiles), women in the top decile of PRS had a 1.54 (95% CI: 1.38, 1.72)-fold increased risk. The performance of the recalibrated 179-variant PRS was not improved (average AUROC=0.56). The PRS ORs did not differ significantly across age strata (P-value for age interaction = 0.63).

Conclusion: Our study shows that both 179 and 313 variant PRS stratify breast cancer risk in women of African ancestry, with attenuated performance compared to that reported in European and in Latina populations. Future work is needed to improve breast cancer risk stratification for women of African ancestry.

Miscarriage, stillbirth, and infant death in an oil-polluted region of the Niger Delta, Nigeria: A retrospective cohort study

OBJECTIVE

To determine the association between oil pollution and miscarriage, stillbirth, and infant death in the Niger Delta region of Nigeria.

METHODS

A retrospective cohort study was undertaken of pregnant women (aged 18-45 years) who attended selected health facilities in regions with high and low exposure to oil pollution from May 14, 2018, to September 27, 2018. A multistage sampling technique was used to randomly select a representative of women with high and low exposure to oil pollution. An interviewer-administered questionnaire was used for data collection. Bivariate and multivariable logistic regression analyses were employed to adjust for confounding factors of miscarriage, stillbirth, and infant death.

RESULTS

In total, 1564 pregnant women were included in the study. Women with high exposure to oil pollution were more likely to experience stillbirth (odds ratio [OR] 1.806; 95% confidence interval [CI] 1.177-2.770) and infant death (OR 2.162; 95% CI 1.409-3.317). However, after adjusting for potential confounders, only infant death was associated with high exposure (adjusted OR 1.843; 95% CI 1.146-2.962). No association was found between miscarriage and high exposure to oil pollution.

CONCLUSION

Women with high exposure to oil pollution are at higher risk of infant death.

Economic status, a salient motivator for medicalisation of FGM in sub-Saharan Africa: Myth or reality from 13 national demographic health surveys

Female Genital Mutilation or Cutting (FGM) and its medicalisation remain a challenge in sub-Sahara African (SSA). Early identification of at-risk women might help in instituting focused counselling against FGM medicalisation. We hypothesised that the risk of medicalised FGM by girls/women is associated with socioeconomic status (SES) their household belongs.

We used 2010–2019 Demographic and Health surveys data from 13 countries in SSA. We analysed information on 214,707 women (Level 1) nested within 7299 neighbourhoods (Level 2) from the 13 countries (Level 3). We fitted 5 multivariable binomial multilevel logistic regression models using the MLWin 3.03 module in Stata. The estimation algorithms adopted was the first order marginal quasi-likelihood linearisation using the iterative generalised least squares.

The odds of FGM medicalisation increased with the wealth status of the household of the woman, with 29%, 45%- and 75%-times higher odds in the middle, richer and richest household wealth quintiles, respectively than those from the poorest households (p < 0.05). The more educated a woman and the better a woman's community SES was, the higher her odds of reporting medicalisation of FGM. Rural community was associated with higher odds of medicalised FGM than urban settings.

Medicalised FGM is common among women from a high socioeconomic, educational background and rural settings of SSA. We recommend a culturally sensitive policy that will discourage perpetuation of FGM, particularly by healthcare providers. Future studies should focus on identifying drivers of FGM among the high social class families in the society in SSA.

Perception Determinants of Women and Healthcare Providers on the Effects of Oil Pollution on Maternal and Newborn Outcomes in the Niger Delta, Nigeria

Purpose

This qualitative study examined the perception determinants of women and their local healthcare providers on exposure to oil pollution and its adverse effects on maternal and newborn outcomes in selected communities with history of oil spillage and gas flaring in the Niger Delta region of Nigeria.

Participants and Methods

Thirty-nine participants were used in this study, which included community women leaders (n=2), women of reproductive ages (n=32) and healthcare providers (n= 3 female nurses and 2 male doctors) in the selected communities in the Niger Delta region of Nigeria. The participants were chosen through purposive sampling. Focus group discussions (FGDs) and in-depth interviews (IDIs) were conducted among the participants and recorded in line with research protocols. The recordings of the FGDs and IDIs were transcribed, coded and analysed using Nvivo 10.

Results

Four major themes emerged relating to the perception determinants of women and healthcare workers on the effects of oil pollution on maternal and newborn outcomes. The first theme relates to the fact that personal experiences influence risk perception. The second theme associated perception with cultural norms, values and practices. The third theme shows that perception is influenced by the level of environmental threat or hazard, while the fourth theme borders around the influence of hospital-related factors on risk perception.

Conclusion

The study strongly suggested that both women and local healthcare providers perceived that oil pollution could have adverse effects on maternal and newborn outcomes. However, their perceptions were influenced by the cultural beliefs of the people, individual experiences, environmental and hospital-related factors. We believe that increasing awareness on the importance of attending antenatal care during pregnancy, making hospital charges affordable for pregnant women, and general environment conduciveness will improve maternal and newborn health in communities affected by oil pollution in the Niger Delta region.

Breast Cancer Knowledge Assessment of Health Workers in Ibadan, Southwest Nigeria

PURPOSE

Breast cancer is the most common cancer among women, and in low- to middle-income countries late-stage diagnosis contributes to significant mortality. Previous research at the University College Hospital, a tertiary hospital in Ibadan, Nigeria, on social factors contributing to late diagnosis revealed that many patients received inappropriate initial treatment.

METHODS

The level of breast cancer knowledge among health practitioners at various levels of the health system was assessed. We developed a tool tailored to local needs to assess knowledge of symptoms, risk factors, treatments, and cultural beliefs. The recruitment included doctors, nurses, and pharmacists in public hospitals, physicians and pharmacists in private practice, nurses and health care workers from primary health care centers, community birth attendants, and students in a health care field from state schools.

RESULTS

A total of 1,061 questionnaires were distributed, and 725 providers responded (68%). Seventy-eight percent were female, and > 90% were Yoruba, the dominant local ethnic group. The majority were Christian, and 18% were Muslim. Median knowledge score was 31 out of 56, and the differences in scores between health care worker types were statistically significant (P < .001). Nearly 60% of the participants believed breast cancer is always deadly. More than 40% of participants believed that keeping money in the bra causes breast cancer, and approximately 10% believed that breast cancer is caused by a spiritual attack.

CONCLUSION

Our questionnaire revealed that, even at the tertiary care level, significant gaps in knowledge exist, and knowledge of breast cancer is unacceptably low at the level of community providers. In addition to efforts aimed at strengthening health systems, greater knowledge among community health care workers has the potential to reduce delays in diagnosis for Nigerian patients with breast cancer.

Influence of a Teaching Session on Breast Self-Examination and Adherence Among Pregnant and Lactating Women in Ibadan, Nigeria

PURPOSE

Educating women on how to examine their breasts can raise breast cancer awareness and early detection rates, especially in low- and middle-income countries. In this study, the influence of a teaching session on breast self-examination (BSE) during pregnancy was evaluated.

METHODS

A quasi-experimental study design was used. A total of 1,248 pregnant women whose pregnancies had a gestational age of 26 weeks or less were recruited from three antenatal clinics representing three tiers of the health care system in Nigeria. They were interviewed using a structured questionnaire, including BSE practice, and taught how to perform BSE using the MammaCare technique at recruitment. At 6 months postpartum, 729 participants were available for phone interview on BSE practice. Adherence to BSE was measured as a binary outcome comparing BSE performances at recruitment with follow-up. Conditional logistic regression analysis was used to determine the differences in BSE practices pre- and postintervention. Multiple logistic regression was used to identify predictors for adherence to BSE training at α = 0.05.

RESULTS

Participants’ mean age was 30.4 ± 4.9 years, 401 (55.0%) attended a secondary health facility for antenatal care, and 78 (10.7%) had breast disorders at recruitment. Two hundred fifty-three (34.7%) said they practiced BSE before recruitment, and 380 (52.1%) did so at follow-up (odds ratio, 1.91; CI, 1.51 to 2.42). Women less likely to adhere were those with breast disorders detected at recruitment (adjusted odds ratio [aOR], 0.55; CI, 0.32 to 0.95) and women recruited from primary and secondary health facilities compared with those from a tertiary health facility (aOR, 0.41; CI, 0.17 to 0.98; aOR, 0.18; CI, 0.11 to 0.29, respectively).

CONCLUSION

Educational interventions can significantly improve screening practices, even if only one session, and should serve as an integral control for breast cancer.

Social reintegration and rehabilitation of obstetric fistula patients before and after repair in Sub-Saharan Africa: A systematic review

Aims: To review how social reintegration and rehabilitation processes are being executed among obstetric patients in Sub-Saharan Africa and highlight projects and programs involved. Methods: This is a systematic review involving a search of relevant literature from PubMed, Google scholar, PsychINFO, African Journals Online, Australian Journals Online, and open access journal of international organizations such as WHO, UNFPA, USAID, Engender Health, Fistula Foundation, and Fistula Care Plus published between 1978 to date. Of the 46 articles identified, 25 were suitable for achievement of this study’s purpose. Results: Sub-Saharan African countries have recognized the overall burden of obstetric fistula and have devised strategies for its’ holistic management. Most countries have National Obstetric Fistula Strategic Frameworks which emphasize multi-sectoral and multidisciplinary approaches other than medical paradigm. Extraordinary among others are: Nigeria, Uganda, Tanzania and Guinea while some countries such as Benin Republic, Chad, Malawi, Mali, and Zambia lack support the at policy level, and have inadequate community outreach programmes. Social reintegration and rehabilitation have been done through the identification of individual patient’s need/s. Upon discharge from hospital, they are counseled, given soap, clothes, transportation fund and are referred to community based projects for elementary education and skills development. Projects and programmes aiming to combat obstetric fistula and restore patients’ self-worth and dignity are: Lamaneh Suisse, and Delta Survie in Mali, Dimol in Niger, Medecins Sans Frontieres (MSF) in Burundi, FORWARD in Nigeria and Sierra Leone, Handicap International in Benin Republic, Women For Africa in Ghana and Liberia, TERREWODE and CoRSU both in Uganda, Hamlin Fistula Ethiopia in Ethiopia, and Safe Motherhood Initiative, Fistula Foundation, Fistula Care Plus, Engender Health, UNFPA, AMREF for Health, WHO and others which cut across the region. Conclusions: Most Sub-Saharan countries have registered progress in assuring effective social reintegration and rehabilitation of obstetric fistula patients although some are still grappling with the issue due to lack of political commitment and inadequate outreach programmes. There is scanty information regarding reintegration and rehabilitation before obstetric fistula repair and yet it would hasten physical and mental wellbeing of the patients as they await repair.

Social Reintegration and Rehabilitation of Obstetric Fistula Patients Before and After Repair in Sub-Saharan Africa: A Systematic Review

Aims: Social reintegration and rehabilitation of obstetric fistula patients before and after repair enhance their overall status, which may be unattainable even with a successful repair. Nonetheless, there is little traceable documentation about it even with supportive programs and projects, the thrust of this study. Methods: This is a systematic review involving a search of relevant literature from PubMed, Google scholar, PsychINFO, African Journals Online, Australian Journals Online, and open access journals of international organizations such as WHO, UNFPA, USAID, Engender Health, Fistula Foundation and Fistula Care Plus published between 1978 to date. Of the 46 articles identified, 25 were suitable for achievement of this study’s purpose. Results:Sub-Saharan African countries have recognized the overall burden of obstetric fistula and have devised strategies for its holistic management. Most countries have National Obstetric Fistula Strategic Frameworks which emphasize multi-sectoral and multidisciplinary approaches other than medical paradigms. Social reintegration and rehabilitation have been done through the identification of individual patient’s need/s.

Conclusions: Effective social reintegration and rehabilitation strategies are still inadequate in Sub-Saharan Africa due to lack of political commitment and inadequate outreach programs. Keywords: obstetric fistula, recto-vaginal fistula, rehabilitation, social reintegration, vesico-vaginal fistula.

Inherited Breast Cancer in Nigerian Women

PURPOSE

Among Nigerian women, breast cancer is diagnosed at later stages, is more frequently triple-negative disease, and is far more frequently fatal than in Europe or the United States. We evaluated the contribution of an inherited predisposition to breast cancer in this population.

PATIENTS AND METHODS

Cases were 1,136 women with invasive breast cancer (mean age at diagnosis, 47.5 ± 11.5 years) ascertained in Ibadan, Nigeria. Patients were selected regardless of age at diagnosis, family history, or prior genetic testing. Controls were 997 women without cancer (mean age at interview, 47.0 ± 12.4 years) from the same communities. BROCA panel sequencing was used to identify loss-of-function mutations in known and candidate breast cancer genes.

RESULTS

Of 577 patients with information on tumor stage, 86.1% (497) were diagnosed at stage III (241) or IV (256). Of 290 patients with information on tumor hormone receptor status and human epidermal growth factor receptor 2, 45.9% (133) had triple-negative breast cancer. Among all cases, 14.7% (167 of 1,136) carried a loss-of-function mutation in a breast cancer gene: 7.0% in BRCA1, 4.1% in BRCA2, 1.0% in PALB2, 0.4% in TP53, and 2.1% in any of 10 other genes. Odds ratios were 23.4 (95% CI, 7.4 to 73.9) for BRCA1 and 10.3 (95% CI, 3.7 to 28.5) for BRCA2. Risks were also significantly associated with PALB2 (11 cases, zero controls; P = .002) and TP53 (five cases, zero controls; P = .036). Compared with other patients, BRCA1 mutation carriers were younger ( P < .001) and more likely to have triple-negative breast cancer ( P = .028).

CONCLUSION

Among Nigerian women, one in eight cases of invasive breast cancer is a result of inherited mutations in BRCA1, BRCA2, PALB2, or TP53, and breast cancer risks associated with these genes are extremely high. Given limited resources, prevention and early detection services should be especially focused on these highest-risk women.

A longitudinal study of the prevalence and characteristics of breast disorders detected by clinical breast examination during pregnancy and six months postpartum in Ibadan, Southwestern Nigeria

Background

Breast disorders cause great anxiety for women especially when they occur in pregnancy because breast cancer is the most common cause of cancer related deaths in women. Majority of the disorders are Benign Breast Diseases (BBD) with various degrees of associated breast cancer risks. With increasing breast cancer awareness in Nigeria, we sought to determine the prevalence and characteristics of breast disorders among a cohort of pregnant women.

Methods

A longitudinal study of 1248 pregnant women recruited in their first trimester- till 26 weeks gestational age consecutively from selected antenatal clinics (ANCs), in Ibadan, Southwest Nigeria. A pretested interviewer- administered questionnaire was used to collect information at recruitment. Clinical Breast Examination (CBE) using MammaCare® technique was performed at recruitment and follow up visits at third trimester, six weeks postpartum and six months postpartum. Women with breast disorders were referred for Breast Ultrasound Scan (BUS) and those with Breast Imaging Reporting and Data System (BIRADS) ≥4 had ultrasound guided biopsy. Statistical analysis was performed using Stata version 14.

Results

Mean age of participants was 29.7 ± 5.2 years and mean gestational age at recruitment was 20.4 ± 4.4 weeks. Seventy-two participants (5.8%) had a past history of BBD and 345 (27.6%) were primigravidae. Overall, breast disorder was detected among 223 (17.9%) participants and 149 (11.9%) had it detected at baseline. Findings from the CBE showed that 208 (69.6%) of 299 breast disorders signs found were palpable lumps or thickenings in the breast, 28 (9.4%) were persistent pain, and 63 (21.1%) were abscesses, infection and mastitis. Twenty out of 127 (15.7%) participants who had BUS performed were classified as BIRADS ≥3. Lesions found by BUS were reactive lymph nodes (42.5%), prominent ducts (27.1%), fibroadenoma (9.6%), breast cysts (3.8%) and fibrocystic changes (2.5%). No malignant pathology was found on ultrasound guided biopsy.

Conclusions

Breast lump is a major breast disorder among pregnant women attending antenatal clinics in Ibadan. Routine clinical breast examination and follow up of pregnant women found with breast disorders could facilitate early detection of pregnancy associated breast cancer in low resource settings.

Using photovoice in adolescent health research: a case-study of the Well-being of Adolescents in Vulnerable Environments (WAVE) Study in Ibadan, Nigeria

Photovoice is a participatory action research method in which people are given cameras and asked to take pictures of specific issues within their community. It is often used among marginalised populations. This method helps people capture specific issues within their community using photographs, critically discuss these issues within a group and present their findings to inform policies within their community. Photovoice has been used in developed countries and among adult participants; however, the extent to which it has been used in developing countries and among adolescent participants is yet to be extensively reported. In this paper, we describe the use of photovoice among male and female adolescents aged 15-19 years who participated in the qualitative phase (phase I) of the Well-being of Adolescents in Vulnerable Environments (WAVE) study in Ibadan, Nigeria. The main study was conducted among adolescents residing in disadvantaged communities within five global cities (Baltimore, USA; Ibadan, Nigeria; Johannesburg, South Africa; New Delhi, India and Shanghai, China). Our findings revealed that adolescents in Ibadan were very eager to participate, remained fully engaged throughout the process and the data obtained were rich and detailed. Some challenges encountered with using this method were that younger adolescents had a tendency to attain saturation when taking pictures much earlier than older adolescents; however, they equally discussed the pictures taken enthusiastically. Overall, our findings affirm that photovoice as a data collection method can be successfully used in research among adolescents in developing countries like Nigeria.

Abstract 4494: Whole genome sequencing reveals different patterns of mutational mechanisms in breast tumors between women of African and European descent

Across race/ethnicities, breast cancer incidence and mortality rates markedly differ. Numerous studies have demonstrated that individuals of African ancestry acquire aggressive, early-onset breast cancers more frequently than other populations for reasons that remain unexplained. The sources of these disparities are complex, and a comprehensive characterization of mutation landscapes amongst indigenous Africans, African Americans (AA), and Caucasian breast tumors has not been performed.

We generated high-depth whole genome sequencing on 31 Nigerian breast cancers (90x) along with matched blood (30x). Breast cancer whole genomes (tumor-normal pairs) from The Cancer Genome Atlas were harmonized with our samples, resulting in a cohort of 31 Nigerians (17 estrogen receptor negative, ER-), 31 AA (22 ER-), and 43 Caucasians (19 ER-). High confidence somatic mutations (substitutions and insertions/deletions) were obtained by using multiple variant callers. Regardless of race, ER- tumors carried similar numbers of mutations than their estrogen receptor positive (ER+) counterparts (Welch t-test p = 0.57 - 0.82). TP53 (64%) was the most frequently mutated gene in ER- disease, while canonical PIK3CA activating mutations were prevalent in ER+ cases (33.3%). Additionally, tumor suppressor genes RB1, NF1, and PTEN were disrupted via structural rearrangements in ∼6 to 15% of samples. Rearrangements in the H3K27 methylation regulator EZH1 were identified in six Caucasians but only one individual with African _ancest. Notably, within coding regions, no striking mutation rate differences amongst races were identified. However, global substitution patterns in ER+ and ER- cancers varied widely by race/ethnicity. In ER- cases, Nigerians carried the highest proportion of canonical APOBEC-associated substitutions, particularly C&gt;T transitions. Conversely, Caucasians with ER+ disease showed a higher proportion of C&gt;T than both Nigerians (Welch t-test p = 0.044) and AA (Welch t-test p = 0.011). Kataegis, or clustered mutations, was most prevalent in Nigerian samples, regardless of ER status. Evidence for kataegis was often corroborated by structural variant breakpoints and aberrant copy number states at the hypermutated locus. Mutation signature analyses highlighted multiple APOBEC signatures, with moderate contribution differences across race and ER status.

Overall, our data suggests potential mutation spectra differences in Caucasian, African American and indigenous African breast tumors. Identification of these molecular characteristics by ancestry and geography may help understand race-associated phenotypes and exposures that drive outcomes in breast cancer.

The media as a critical determinant of the sexual and reproductive health of adolescents in Ibadan, Nigeria

PURPOSE

Findings on the influences of the media on the sexual health of adolescents in vulnerable communities in Ibadan are presented.

METHODS

Phase I of the WAVE study in Ibadan was conducted among participants purposively selected from disadvantaged communities in Ibadan North Local Government Area (LGA). Qualitative research methods (key informant interviews, in-depth interviews, community mapping and focus group discussions as well as photovoice sessions) were utilized.

RESULTS

A total of 132 key informants and adolescents (aged 15-19 years) participated. The key informants were teachers, youth workers, and religious leaders working with adolescents within the LGA. Respondents mentioned a number of media technologies (such as television, cellphones, computers, the Internet as well as online and hard copy novels) that adolescents are exposed to in contemporary times. They said these had positive and negative influences on them. Adolescents often looked up information on the Internet although it was mostly used as a means of meeting and communicating with friends. Respondents stated that the media had a strong influence on adolescents' sexual and reproductive health especially regarding dating, relationships, and sexual practices. It also exposed them to pornography and Internet fraud.

CONCLUSIONS

The study highlighted the important role the media plays in the sexual health of adolescents in Ibadan. Intervention programmes need to make use of this medium to reach out to more adolescents and measures should be instituted to prevent adolescents from misusing the media.

Social barriers to diagnosis and treatment of breast cancer in patients presenting at a teaching hospital in Ibadan, Nigeria

Globally, breast cancer is the most frequent malignancy in women, and stage at diagnosis is a key determinant of outcome. In low- to middle-income countries, including Nigeria, advanced stage diagnosis and delayed treatment represent a significant problem. That social barriers contribute to delay has been noted in previous research; however, few specific factors have been studied. Using semi-structured interviews, this study identifies social barriers to diagnosis and treatment for patients who presented at University College Hospital Ibadan, Nigeria. Transcripts from the interviews were coded and analysed thematically. Thirty-one patients and five physicians were interviewed. The median age of patients was 51 (range: 28 to above 80), 83% were Christian and 17% were Muslim. Preliminary analysis showed that delays in diagnosis reflected a lack of education as well as the utilisation of non-physician medical services such as pharmacists. Delays in treatment were often due to fear of unanticipated surgery and cost. The majority of women did not know the cause of their breast cancer, but some believed it was caused by a spiritual affliction. This study suggests that further education and awareness of breast cancer for both patients and providers is needed in order to increase early stage diagnosis.

Knowledge and use of emergency contraception by medical doctors on internship in a tertiary healthcare facility in Nigeria

CONTEXT

Emergency contraception (EC) is widely used to prevent unwanted pregnancy and it is largely adopted in many countries as over the counter drug to improve access.

AIMS

To determine and compare the correct knowledge, attitude and current use of EC among newly graduated medical doctors (MDs).

SETTINGS AND DESIGN

A cross-sectional study conducted among 255 newly graduated MDs at the University College Hospital, Ibadan, Nigeria.

MATERIALS AND METHODS

A pretested self-administered questionnaire was used to obtain data from consenting participants.

STATISTICAL ANALYSIS USED

Descriptive, bivariate, and multivariable analyses were performed, and statistical significance was set at 0.05. Statistical Package for Social Science version 15.0 (Chicago, IL, USA) software was used.

RESULTS

The mean age of the respondents was 27.2 years (standard deviation = 2.1). The commonest indication for emergency contraceptive use mentioned was rape-96.5%. About 70% support EC in Nigeria, while about a quarter (26.9%) routinely counsel women about ECP use. About 21% of respondents currently use EC. Logistic regression analysis revealed significant results for gender [odds ratio (OR) =3.64; 95% confidence interval (CI) OR = 1.31-10.01), religion (OR = 0.26; 95% CI OR = 0.11-0.630) and marital status (OR = 0.19; 95% CI = 0.07-0.56).

CONCLUSION

The correct knowledge and professional disposition toward EC as a form of contraception is low. We recommend that in-service training should focus more on EC to improve the quality of their knowledge and attitude towards it.

Uncomplicated midvaginal vesico-vaginal fistula repair in ibadan: a comparison of the abdominal and vaginal routes

BACKGROUND

Obstetric fistula is a resultant effect of prolonged obstructed labour. The best surgical management of simple uncomplicated fistula determines the outcome of care.

OBJECTIVE

To compare outcome of uncomplicated mid-vaginal fistula between vaginal and abdominal route of repair.

MATERIALS AND METHOD

This was a hospital based retrospective study conducted at the University College Hospital, Ibadan from January, 2000 till December, 2006.

RESULT

Of the 71 midvaginal fistulae managed, 40.8% had abdominal repair while the remainder were through vaginal approach. The overall repair success rate was 79.2% with comparable outcome in both groups-78.3% for the abdominal and 80% for the vaginal group (p=0.999). The duration of hospital stay did not differ significantly between the groups (p=0.972). Post operative complications were found in 41.4% of the abdominal group compared to none in the vaginal group (p<0.001). The complications were failed repair (20.7%) and urinary tract infection (20.7%). The mean estimated blood loss was 465.5ml in the abdominal group compared to 332.9ml for the vaginal group (p=0.303).

CONCLUSION

Despite the comparable surgical repair outcome of the two methods, the vaginal approach is associated with lesser blood loss and lower risk of post-operative complications. It is recommended that the vaginal route should be employed in the repair of uncomplicated midvaginal fistula unless there are other compelling reasons to the contrary.

Group psychological therapy in obstetric fistula care: a complementary recipe for the accompanying mental ill health morbidities?

The objective of this study is to determine the impact of group psychological therapy (GPT) on the mental health of obstetric fistula patients. It was a comparative pre and post intervention design. All patients had GPT prior to surgery and mental health assessment conducted before and after surgical repair. There was a significant reduction in proportion of those with severe mental health status after surgery. Specifically, the proportion of those with depression score of 4 and above reduced from 71.7% to 43.4%, and those with score of less than 4 increased from 28.3 to 56.6 percent. There was a significant reduction in those with very low self-esteem from 65.0% to 18.3%. Suicidal ideation reduced generally; severe (15.0 to 0%), moderate (16.7 to 5.0%) and mild (25.0 to 21.7%) and those without increased (43.3 to 73.3%). In conclusion, GPT is a useful adjunct to OF care as it improves their overall mental health status.

Vesico-vaginal fistula repair as a day case: is it a worthy venture?

Two vesico-vaginal fistula patients who were successfully managed with outpatient care as an alternative approach, to ensure early access to care and integration into their family. The two patients had simple uncomplicated mid-vagina fistulae surgically repaired with local infiltrative anaesthesia. We suggest some selection criteria and clinical guidelines that can facilitate successful treatment by this choice of care.

Maternal demand for cesarean section: perception and willingness to request by Nigerian antenatal clients

Background

Contrary to the widely reported aversion to cesarean section in the West African subregion, maternal demand for cesarean section (MDCS) seems to be on the increase, and there is little evidence to explain this trend. The purpose of this study was to determine the perception and attitudes of Nigerian antenatal clients towards MDCS, their willingness to request MDCS, and the relationship between willingness to request MDCS and sociodemographic characteristics.

Methods

A cross-sectional survey was undertaken among 843 antenatal clients at Agbongbon/Orayan primary health care centers (PHCs), Adeoyo Maternity Hospital (SHC), and UCH Ibadan (THC), representing the three different levels of health care in Nigeria, ie, primary, secondary, and tertiary.

Results

The proportion of women aware of MDCS was 39.6%. Predictors of awareness were education and type of health facility. Women from THC and those with tertiary education and above were more likely to be aware of MDCS than others (P = 0.001). Doctors were major sources of information on MDCS (30.8%) as well as friends (24.3%). Common reasons reported for MDCS were fear of labor pains (68.9%), and fear of poor labor outcome (60.1%), and fear of fecal (20.2%) and urinary incontinence (16.8%). More women from the THC than other facilities believed that requests for MDCS should be granted (P < 0.001). However, willingness to request MDCS was low (6.6%). More than 50% of those willing to request MDCS would likely be criticized, mainly by their husbands. On multiple logistic regression, respondents at the THC were significantly more likely than those at the SHC or the PHCs to request cesarean section and to favor a woman’s right of autonomy to choose her mode of delivery.

Conclusion

The decision for MDCS is a difficult one, because willingness is low and criticism by partners of those who choose MDCS is high. Provision of epidural anesthesia and improved safety of vaginal delivery is recommended. This may prevent Nigerian women from making a difficult choice for MDCS based on fear of pain and poor labor outcome. The role of the male partner should be taken into consideration in order to make sustainable policies or guidelines for MDCS in developing countries.

Theories of urinary incontinence causation: aetiological descriptions by sub-Saharan African women

OBJECTIVE

To describe the perceived causes of urinary incontinence (UI) and factors associated with awareness of causes of UI among women in the community.

STUDY DESIGN

Secondary analysis of data extracted from the Ibadan Urinary Incontinence Household Survey (IUIHS), a multi-stage community survey conducted among 5001 women in Nigeria.

RESULTS

The mean age was 34.8 years (SD=14.2). The majority had at least secondary education and were currently married. Within this population, 13% had ever leaked urine. On their perception of possible aetiological factors of UI, 20.5% mentioned pelvic floor or bladder-related causes such as stress incontinence triggers and bladder problems; 14.6% mentioned uncontrollable factors such as medical comorbidity, age and prior surgery; 8.8% attributed the cause to being female; and 6.8% mentioned sex-related factors. Multiple logistic regression analysis revealed significantly lower odds of awareness of the aetiology of urinary incontinence among women aged less than 30 years, those with lower level of education, rural women, those with five or more children and women without history of urine leakage.

CONCLUSIONS

The study shows a low level of awareness of possible cause of UI amongst women surveyed. We recommend health education and mobilization of women on the right aetiological factors of UI.

Help-seeking behavior among women currently leaking urine in Nigeria: is it any different from the rest of the world?

OBJECTIVE

We examined help-seeking behaviors and factors influencing their choice of hospital care in women currently leaking urine.

MATERIALS AND METHODS

This study was part of a multistage community survey conducted among 5001 women in Nigeria who participated in the Ibadan Urinary Incontinence Household Survey. Help-seeking behavior was analyzed among 139 respondents currently leaking urine within the population surveyed.

RESULTS

The mean age of those currently leaking urine was 35.7 years (standard deviation = 15.8). Only 18 (12.9%) had ever sought help, of which 15 had received hospital care. Logistic regression analysis showed that the odds of seeking hospital care was higher among less educated women (odds ratio [OR] = 4.05, 95% confidence interval [CI]: 1.17-13.89) and among those with severe incontinence (OR = 4.20, 95% CI: 1.24-14.29). Reasons mentioned for not seeking hospital care include a belief that the condition is not life-threatening (51.2%), do not believe there is treatment (18.2%), lack of funds (1.7%), too shy to disclose (2.5%), afraid of complications (1.7%), other (2.5%), and no reason (22.3%).

CONCLUSION

This study shows that very few women, currently experiencing urinary incontinence have sought medical care (approximately 1 in 10); and that the barriers identified are similar to those identified in previous studies, except that these women lack the necessary funds to seek care.

Assessing the role of the non-pneumatic anti-shock garment in reducing mortality from postpartum hemorrhage in Nigeria

BACKGROUND/AIMS

Postpartum hemorrhage (PPH) is the leading cause of maternal mortality. The non-pneumatic anti-shock garment (NASG), a first-aid lower-body pressure device, may decrease mortality.

METHODS

This pre-intervention/NASG study of 288 women was conducted in four referral facilities in Nigeria, 2004-2008. Entry criteria: women with PPH due to uterine atony, retained placenta, ruptured uterus, vaginal or cervical lacerations or placenta accreta with estimated blood loss of ≥750 ml and one clinical sign of shock. Differences in demographics, conditions on study entry, treatment and outcomes were examined. t tests and relative risks with 95% confidence intervals were calculated for primary outcomes - measured blood loss and mortality. Multiple logistic regression analysis was performed to examine independent association of the NASG with mortality.

RESULTS

Mean measured blood loss decreased by 80% between phases. Women experienced 350 ml of median blood loss after study entry in the pre-intervention and 50 ml in the NASG phase (p < 0.0001). Mortality decreased from 18% pre-intervention to 6% in the NASG phase (RR = 0.31, 95% CI 0.15-0.64, p = 0.0007). In a multiple logistic regression model, the NASG was associated with reduced mortality (odds ratio 0.30; 95% CI 0.13-0.68, p = 0.004).

CONCLUSION

The NASG shows promise for reducing mortality from PPH in referral facilities in Nigeria.

Attitude of infertile women to child adoption in Nigeria

Infertility has serious consequences especially in Africa where a high premium is place on child bearing. An interviewer-administered questionnaire was administered on 396 consenting women seeking infertility treatment at the gynaecological clinic of the University College Hospital, Ibadan in an attempt to assess the attitude of infertile women in Nigeria to child adoption and its acceptability as a management option for infertility. Most (64%) believed its culturally unacceptable and only 17% will try it as an option. Sustained advocacy, community mobilization and enactment of supportive laws were some of the suggestions made by respondents to improve its uptake.

Obstetric hemorrhage and shock management: using the low technology Non-pneumatic Anti-Shock Garment in Nigerian and Egyptian tertiary care facilities

Background

Obstetric hemorrhage is the leading cause of maternal mortality globally. The Non-pneumatic Anti-Shock Garment (NASG) is a low-technology, first-aid compression device which, when added to standard hypovolemic shock protocols, may improve outcomes for women with hypovolemic shock secondary to obstetric hemorrhage in tertiary facilities in low-resource settings.

Methods

This study employed a pre-intervention/intervention design in four facilities in Nigeria and two in Egypt. Primary outcomes were measured mean and median blood loss, severe end-organ failure morbidity (renal failure, pulmonary failure, cardiac failure, or CNS dysfunctions), mortality, and emergency hysterectomy for 1442 women with ≥750 mL blood loss and at least one sign of hemodynamic instability. Comparisons of outcomes by study phase were assessed with rank sum tests, relative risks (RR), number needed to treat for benefit (NNTb), and multiple logistic regression.

Results

Women in the NASG phase (n = 835) were in worse condition on study entry, 38.5% with mean arterial pressure <60 mmHg vs. 29.9% in the pre-intervention phase (p = 0.001). Despite this, negative outcomes were significantly reduced in the NASG phase: mean measured blood loss decreased from 444 mL to 240 mL (p < 0.001), maternal mortality decreased from 6.3% to 3.5% (RR 0.56, 95% CI 0.35-0.89), severe morbidities from 3.7% to 0.7% (RR 0.20, 95% CI 0.08-0.50), and emergency hysterectomy from 8.9% to 4.0% (RR 0.44, 0.23-0.86). In multiple logistic regression, there was a 55% reduced odds of mortality during the NASG phase (aOR 0.45, 0.27-0.77). The NNTb to prevent either mortality or severe morbidity was 18 (12-36).

Conclusion

Adding the NASG to standard shock and hemorrhage management may significantly improve maternal outcomes from hypovolemic shock secondary to obstetric hemorrhage at tertiary care facilities in low-resource settings.

Social support during childbirth as a catalyst for early breastfeeding initiation for first-time Nigerian mothers

Background

Initiation of breastfeeding can be difficult in a busy maternity centre with inadequate manpower and social support. This study aims to explore the role of psychosocial support offered by companions on breastfeeding initiation among first-time mothers.

Methods

This is a secondary data analysis of a randomised controlled trial conducted among women attending the antenatal clinic of the University College Hospital, Ibadan, Nigeria in 2007. Those in the experimental group were asked to bring someone of their choice to the labour room to act as a companion; the comparison group received standard care. The results of 209 HIV negative women who had vaginal births were analysed. The main outcome measure was time to initiation of breastfeeding after childbirth.

Results

Of the total, 94 had companions during labour while 115 did not have a companion. The median time to breastfeeding initiation was significantly shorter in those with companions compared to controls (16 vs. 54 minutes; p < 0.01). The cumulative survival analysis indicated that all in the treatment group had initiated breastfeeding by 26 minutes, while among the control group none had commenced at 30 minutes post-delivery with some as late as 12 hours. After Cox regression analysis was used to adjust for possible confounders, the outcome still showed a significant hazard ratio of 207.8 (95%CI 49.2, 878.0; p < 0.01) among women who were supported by a companion.

Conclusion

Use of companions during labour is associated with earlier time to breastfeeding initiation among first-time mothers in Nigeria.

The role of ethnicity on pain perception in labor among parturients at the University College Hospital Ibadan

AIMS

In developing countries, the major mechanism by which parturients cope with labor pain is psychological. This study aims to assess the effect of ethnicity on the perception of pain by parturients in labor at the University College Hospital, Ibadan.

MATERIALS AND METHODS

The study was conducted between the 1 November 2006 and the 30 March 2007 at the University College Hospital Ibadan. The main outcome measure was pain perception assessed by the Box Numerical Scale (BNS). Univariate analysis was by t-test for continuous variables and chi2 test for categorical variables. The multiple linear regression method was utilized for multivariate analysis. The level of statistical significance was set at P < 0.05.

RESULTS

The lowest adjusted mean BNS score was found in the Yoruba ethnic group: they had scores lower than the mean scores for the other ethnic groups (-0.636 [95% confidence interval (CI) -0.959, -0.313]). The presence of a doula also reduced the mean BNS scores significantly (-0.533 [95% CI -0.844, -0.222]). Increasing parity also reduced pain scores (-0.182 [95% CI -0.342, -0.022]). Increasing educational attainment increased pain scores in labor (0.189 [95% CI 0.017, 0.361]). The influence of increasing age was not statistically significant in this model. In conclusion, ethnicity of the parturient relative to that of the predominant ethnicity in the place of birth has a significant effect on the perception of labor pain by the parturient. In our resource-challenged environment, trained doulas may help make labor less painful for the parturient.

Assessment of the effect of psychosocial support during childbirth in Ibadan, south-west Nigeria: a randomised controlled trial

OBJECTIVE

To assess the effect of psychosocial support on labour outcomes.

METHODOLOGY

A randomised control trial conducted at the University College Hospital Ibadan, Nigeria, from November 2006 to 30 March 2007. Women with anticipated vaginal delivery were recruited and randomised at the antenatal clinic. The experimental group had companionship in addition to routine care throughout labour until two hours after delivery, while the controls had only routine care. The primary outcome measure was caesarean section rate. Others included duration of active phase, pain score, time of breast-feeding initiation and description of labour experience. Multivariable analyses were used to adjust for potential confounders. The level of statistical significance was set at 5%.

RESULTS

Of the 632 recruited, 585 were eventually studied: 293 and 292 were in experimental and control groups, respectively. Husbands constituted about two-thirds of the companions. Women in the control group were about five times more likely to deliver by caesarean section (95% confidence interval (CI) 1.98-12.05), had significantly longer duration of active phase (P < 0.001), higher pain scores (P = 0.011) and longer interval between delivery and initiation of breast-feeding (P < 0.001). However, those in experimental group had a more satisfying labour experience (odds ratio 3.3 95% CI 2.15-5.04).

CONCLUSION

Women with companionship had better labour outcomes compared to those without. It is desirable to adopt this practice in our health-care settings as an alternative strategy to provide comparable quality services to would-be mothers in labour.

Pattern of mental ill health morbidities following hysterectomy for benign gynaecological disorders among Nigerian women

Objective

to compare the pre and post hysterectomy mental ill health (MIH) status and also, to determine whether there is any association with the surgical indication.

Methodology

An observational study, conducted among women scheduled for hysterectomy at the University College Hospital, Ibadan from January till June 2005. The MIH morbidities were assessed using a validated general health questionnaire (GHQ) before and after the surgery by trained research assistant. The score of 4 and above was used as the cut off. Cross tabulations were performed to detect any association and also to compare pre and post hysterectomy mental health status. The level of statistical significance was set at P < 0.05.

Results

Of the 50 women recruited, 45 participated in the study. The age range of the participants was 35 to 63 years with a mean of 48.6 (SD = 0.6) years. Anxiety related disorder was present in 20 (44.4%), and depression in 3 (6.7%) before hysterectomy. Post surgery, there was significant increase in those with anxiety by 6.8% and a reduction in the proportion of depressive illness by 2.3%. Uterine fibroid as a preoperative diagnosis, had significant association among those with anxiety related disorder (68.4%) and depression (10.5%).

Conclusion

This study suggests that mental ill health may complicates hysterectomy for benign uterine pathology among Nigerian women, and that anxiety related disorders increases after operation with the highest proportion in those with clinical diagnosis of Uterine Fibroid. We recommend adequate preoperative counseling using properly trained psychologists when affordable to minimize these morbidities.

Human immunodeficiency virus antibody in patients with cancer of the uterine cervix undergoing radiotherapy: clinical stages, histological grade and outcome of radiotherapy

One hundred and twenty consecutive patients with cancer of the uterine cervix were screened for human immunodeficiency virus (HIV) seropositivity before and after radiotherapy. The severity of the disease in terms of clinical staging and histological grading of HIV seropositive women was compared with that of seronegative women. The result showed a prevalence rate of 4.2% for HIV seropositivity which was similar to the rate quoted for the general populace in Nigeria. The HIV seropositive women presented with more severe disease state than the HIV seronegative women. The mean duration of remission was significantly shorter in the HIV seropositive women following radiotherapy (18.36+/3.96 vs. 24.24+/-6.3 months). It was concluded that HIV infection increases the severity and progression of cancer of the cervix in Nigerians. Radiotherapy has no effect on the patients' seropositivity and possibly no effect on the virus. A more aggressive treatment of carcinoma of the cervix and closer follow-up of HIV seropositive patients following treatment are necessary.

Acceptability of child adoption as management option for infertility in Nigeria: evidence from focus group discussions

Infertility remains a global health challenge with devastating psycho-social consequences in many African communities. Adoption that may serve as an alternative strategy for the affected couples is not widely practiced. This study was conceptualized to assess the acceptability of child adoption as a management option by Nigerians. Twelve focus group discussions were held involving three communities stratified into inner core, transitory and peripheral, within Ibadan metropolis, South-Western Nigeria from May to July 2008. The participants were purposively selected based on gender and age group. The barriers mentioned were cultural practices, stigmatization, financial implications, and procedural bottle-necks. Measures suggested to curb these negative attitudes were advocacy, community mobilization and enactment of supportive law that will protect all parties involved.

Determinants of post-caesarean wound infection at the University College Hospital Ibadan Nigeria

OBJECTIVE

To determine the risk factors that predispose patients to post-caesarean wound infection at a tertiary health institution in developing country.

METHOD

It was an observational study of all women that had caesarean (elective and emergency) delivery between July and September, 2004. The outcome of their post-caesarean wound was assessed. Statistical analysis (Bivariate and logistic regression) of the identified risk factors in patients who developed wound infection was performed at a 95% level of confidence.

RESULTS

The post-caesarean wound infection rate was 16.2%. The identified risk factors were lower educational status, multiple pelvic examination, offensive liquor at surgery and patients that are unbooked. Following logistic regression, women with up to primary school were 20 times more likely than those with secondary education and above to develop wound infection (95% CI OR = 1.8 to 250.0).

CONCLUSION

The outcome showed that the identified determinants of post-caesarean wound infection were comparable with earlier reports. Women with lower educational status are more at risk in this study. Therefore, these women need special attention to reduce the risk.

Menstrual characteristics of secondary school girls in Ibadan, Nigeria

BACKGROUND

Disturbances of menstrual function are the commonest complaints among adolescents. Disorders of menstruation may have implications for future reproductive health.

OBJECTIVE

To assess menstrual patterns among school girls in Ibadan, south-western Nigeria.

METHODS

This was cross-sectional descriptive study in which 1,213 apparently healthy school girls were selected by multistage sampling technique in fifteen secondary schools from the five local governments within the metropolis. Information about details of menstrual experience was obtained with a self-administered questionnaire.

RESULTS

The girls were aged between 9 and 23 years. Majority of respondents 768 (633%) experienced normal cycle length, 391 (32.2%) had short cycles; and 55 (4.5%) had cycle length greater than 35 days. Prevalence of normal cycles increased with increasing age; abnormalities of cycle length tended to decrease with increasing age (p < 0.01). The majority, 1,152 (95%), had normal menstrual loss. The majority 882 (72.7%) experienced dysmenorrhoea; severe dysmenorrhoea was reported by 154 (12.7%). Cycle length was not associated with presence of dysmenorrhoea (p > 0.05); 695 (57.3%) had symptoms of pre-menstrual syndrome.

CONCLUSION

Prevalence of menstrual abnormalities among adolescent schoolgirls is high. More attention should be paid to identify and treat these menstrual morbidities.

Sexual behaviour of in-school adolescents in Ibadan, South-West Nigeria

This study was a crossectional survey conducted among 716 senior secondary school adolescents in Ibadan from March to August 2005. The result of 695 that was analyzed revealed that the mean age of 15 +/- 2.6years. 28.3% of the respondents had previous sexual exposure with higher proportions being male (p = 0.00043). Majorities' first sexual exposure was unplanned. Family settings and educational level do not have significant influence on the previous sexual exposure. The methods of sexual activity were mainly through vagina route while some had also practiced oral and anal sex. Most of those that are sexually exposed had more than one partner. About half of the respondents learn about sex from their friends while others through their parents and media. We conclude that in-school adolescents practiced unsafe sexual activity and they are therefore predisposed to STI/HIV and other reproductive health risks.

Comparative evaluation of haemoglobin estimation amongst pregnant women in Ibadan: Hemocue - B haemoglobin analyzer versus haemiglobincyanide (standard) method as the gold standard

This was a comparative crossectional study that was conducted among 557 antenatal women at the University College Hospital, Ibadan, Nigeria between 1st April and 30th May 2006. The study compared the accuracy of haemoglobin estimation using an automated HemoCue B analyzer kit with a standard laboratory method (haemogloincyanide) as the gold standard. The result showed a positive correlation of HaemoCue haemoglobin results when compared with the standard methods (Pearson's correlation coefficient = 0.892; p value = 0.000). We concluded that the use of the automated HemoCue kit for haemoglobin estimation gives an objective assessment which overcomes the challenge of extra skilled manpower or power outages in rural areas thereby enhancing access to quality of care in resource poor countries.

The influence of social support on the duration of breast-feeding among antenatal patients in Ibadan

In Nigeria, breast-feeding has been shown to be very closely related to infant survival. Prolonged and adequate breast-feeding is critical to most infants' nutritional health and growth. This study aims to determine the influence of family support on the duration of exclusive and total breast-feeding of infants of antenatal patients. This cross-sectional study was conducted between 1 September and 30 December 2005. The tool was a structured questionnaire. The main outcome variables were the duration of breast-feeding; both total and exclusive explanatory variables were mainly related to support obtained during breast-feeding from husband and older female relations. Husbands support significantly increased the total duration of breast-feeding by a mean of 1.69 months (95% CI 0.88, 2.51), however, exclusive breast-feeding was not significantly affected by the husband's support (OR 0.94; 95% CI 0.63, 1.39). Female support had a significant influence on both the total duration of breast-feeding which is increased by a mean of 1.08 months (95% CI 0.14, 2.02), and the adequate conduct of exclusive breast-feeding (OR 1.83; 95% CI 1.17, 2.86). The cultural practice of having additional female support in the postpartum period has been shown by this study to be beneficial. Therefore, this cultural practice should be encouraged and catalogued as a beneficial cultural practice. This practice is also cheap and sustainable.

Local anesthesia: an appropriate technology for simple fistula repair

OBJECTIVES

To assess the efficacy of local infiltrative anesthesia with lidocaine hydrochloride in patients undergoing the surgical repair of a simple vesico-vaginal fistula.

METHODS

The study was carried out with 21 patients undergoing the repair of a simple midvaginal vesico-vaginal fistula. The patients' perception of pain was evaluated intraoperatively.

RESULTS

Most patients indicated that the anesthetic agent provided adequate analgesia, and all fistulas were repaired successfully without postoperative complications.

CONCLUSION

Repairing simple vesico-vaginal fistulas is feasible with a local infiltrative anesthetic.

A review of postoperative care for obstetric fistulas in Nigeria

Nigeria harbors an estimated 40% of all the women affected with obstetric fistulas today, and at the current rate of treatment in this country, it would take about 300 years to treat them if no new fistulas occurred. This situation obviously runs contrary to the ideals of the United Nations Millennium Development Goals and needs to be reversed. We reviewed the literature on fistula treatment in Nigeria to identify strategies and practices that, if adopted, would likely accelerate the pace of fistula repair and improve postoperative fistula care in this country. A comprehensive nationwide survey, a stronger political will and commitment of resources, a systematic postoperative care and follow-up, more fistula centers, and more fistula campaigns are necessary. Technically, the involvement of all surgeons trained in fistula repair and an experience-based postoperative management protocol will relieve the disease burden carried by women living with fistulas in Nigeria.

One-stage repair for combined fistulas: Myth or reality?

OBJECTIVE

The repair of combined vesico-vaginal fistulas (VVFs) and recto-vaginal fistulas (RVFs) is challenging to both surgeon and patient. The multistage approach involves at least 3 surgical sessions, all associated with morbidity and sometimes with a colostomy procedure as well. The outcomes of the 1-stage approach were examined.

METHODS

Twenty patients aged between 16 and 38 years were recruited for a multicenter study conducted from March 2005 to August 2006. Prolonged obstructed labor was the cause of all fistulas. The VVFs were mainly midvaginal (60%), juxtaurethral (25%), and juxtacervical (15%). The RVFs measured between 1 and 3 cm, they were low in 70% of cases, and 1 was associated with fourth-degree perineal tear. Bowel preparation was performed in all patients prior to surgery. No patient underwent temporary colostomy.

RESULTS

Both VVFs and VVFs were successfully closed in all patients, as evidenced by the continence dye test.

CONCLUSION

The combined repair relieves economic constraints and emotional challenges, and it accelerates restoration to health and social reintegration for women affected with both VVFs and RVFs.

Parameters of nutrition in school girls in southwestern Nigeria

OBJECTIVES

To document trends in parameters of nutrition in south-western Nigerian school girls in comparison with earlier reports and provide baseline data for future comparison.

DESIGN

A cross-sectional study.

SETTING

Fifteen secondary schools from the five local governments in Ibadan, Oyo State in south-western Nigeria.

SUBJECTS

One thousand six hundred and seventy five apparently healthy female students aged between nine and twenty three years.

RESULTS

One thousand six hundred and seventy three questionnaires were analysed. The mean age, mean height and mean body weight were 15.45 years +/- 2.06 (SD), 154.98cm +/- 8.4(SD) and 46.09kg +/- 8.8 (SD) respectively. The mean body fat was 11.12kg +/- 4.6 (SD); mean lean body mass (LBM) was 34.96kg +/- 4.6 (SD); mean total body water (TBW) was 25.17L +/- 3.3 (SD) and the mean body index (BMI) was 19.07kg/m2 +/- 2.7 (SD). Girls from upper socio-economic background had significantly higher values of anthropometric measurements and body composition for each age than lower socioeconomic class girls. Compared with their peers from another Nigerian city investigated two decades ago, girls in this study were significantly lighter and shorter.

CONCLUSION

The study revealed a decline in nutritional parameters among adolescents. The implications of these findings for the reproductive health of Nigerian women are discussed. Serial studies to monitor trends in adolescents are recommended.

Grandmultiparity--trends and complications: a study in two hospital settings

Pregnancy after the fifth delivery is viewed with anxiety, especially by obstetricians in developing countries working with inadequate facilities. High parity is still common with serious consequences to the fetus, the mother, the family and society. In the last 40 years, non-governmental, national and international efforts have been made to reduce fertility rates. We therefore intended to determine the trend in the grandmultiparity rates from 1 January 1987 to 31 December 1994 in the South Western part of Nigeria. The obstetric performance of these grandmultiparae in two different settings were to be compared. This was a retrospective, case-note analysis of all the grandmultiparae delivered at the University College Hospital (UCH) (Group A) and the Oluyoro Catholic Hospital (OCH) (Group B), both in Ibadan city. The former is a tertiary health care centre while the latter is a secondary centre. The socio-clinico-demographic characteristics of these patients were collated and analysis and comparison performed using EPI-INFO software. In Group A, 828 grandmultiparae were seen among 9215 deliveries, a rate of 8.99% (10.90% in 1987 to 3.36% in 1994). In Group B, there were 1940 cases among 22 587 deliveries, i.e. 8.59% (12.75% to 6.07%), respectively. The modal age group was 31-35 years, and women above 35 years formed one-third of cases. The parity group 5-7 was the most frequent in both groups (91.6% vs. 94.9%). Only two mothers (both in group B) had parity above 10. Booked patients formed a larger percentage in Group B than in Group A (85.8% vs. 69.7%, respectively). In Group B 85.9% had spontaneous vertex delivery as opposed to 66.3% in Group A. Caesarean section was the mode of delivery in 9.0% and 24.2% in Groups B and A, respectively. Equal percentages had breech delivery. The modal birth weight was 2.51-3.00 kg in both groups. Macrosomic babies formed 3.7% in Group A and 2.4% in Group B, while low birth weight babies formed 17.7% and 11.7% in Groups A and B, respectively. The crude perinatal death ratio was 123/1000 in Group A and 68/1000 in Group B. Antepartum haemorrhage, anaemia and premature rupture of membranes in Group A and anaemia, hypertension and antepartum haemorrhage in Group B were the most common pregnancy complications noted. In labour, abnormal lie/presentation, prolonged labour and premature labour in Group A and abnormal lie/presentation, antepartum haemorrhage and birth asphyxia in Group B formed the majority of the complications. The most common puerperal complications were primary postpartum haemorrhage, wound/genital sepsis in Group A and anaemia and primary postpartum haemorrhage in Group B, respectively. Maternal death ratio was 10.85/100 000 total deliveries in Group A and 35.42/100 000 in Group B. High parity is still common in developing countries, although the incidence is declining, with rates of 3.4% and 6.1% of total deliveries in Groups A and B, respectively. More patients are delivered per abdomen at UCH compared to OCH. The perinatal mortality rate is higher at UCH than OCH but the maternal mortality rates follow the reverse. Recommendations are made concerning the reduction in high parity rates and its associated complications.

Outcome of twin pregnancies in patients with haemoglobinopathies--case reports

Pregnancy in patients with haemoglobinopathy is associated with increased risk of maternal and perinatal morbidities and mortalities. Multiple pregnancy is potentially more hazardous than singleton pregnancy. There is a dearth of information concerning multiple pregnancies in patients with haemoglobinopathy. Four of such patients seen in the obstetric service of the University College Hospital, Ibadan are presented here and discussed. Increased surveillance and elective caesarean delivery are suggested in the management of these patients.

Maternal and cord blood lactate and 3-hydroxybutyrate levels during labour in Nigerian women

In this preliminary study, maternal and fetal blood lactate and 3-hydroxybutyrate (3-OHB) levels were assayed by specific enzymatic spectrophotometric methods in two groups of parturient Nigerian women during the three labour stages and their newborn: (i) thirty two women with babies' Apgar score > or = 6, and, (ii) eighteen women with babies' Apgar scores á 5. Cord blood was collected within 1 min. of cord clamping. In all the patients there was a lactate gradient between the foetus and mother. Neonates with Apgar score < 5 had greater cord blood 3-OHB levels. This could indicate reduced utilisation and/or increased production of this metabolite. Since in states of glucose deprivation as could be found in placenta insufficiency, 3-OHB is utilised by the foetus for the synthesis of essential cerebral lipids. It is speculated that the immediate poor clinical condition of babies with low Apgar scores may be a consequence of reduced synthesis of these cerebral lipids as they were unable to utilise circulating 3-OHB. The rapid response to routine resuscitative measures in these newborn babies could also indicate improved 3-OHB utilisation secondary to an improved tissue oxygenation status. These hypotheses from the basis for further studies.
