Coronavirus Disease 2019 Vaccination Coverage and Seropositivity amongst Nigerians 18 Years Old and Above.

BACKGROUND: This was a cross-sectional community-based survey to study the prevalence of serum antibodies against the severe acute respiratory syndrome coronavirus 1 (SARS-COV-1) and determine possible source of antibodies as to whether from vaccination or from natural infection as well as attempt to compare antibody levels in response to the different four types of vaccines administered in Nigeria. METHODS: A cross-sectional community-based study of the prevalence of serum antibodies against all four vaccine types used in Nigeria amongst a representative sample of people aged 18 years and above in the six geopolitical zones of the country using a multistage sampling technique covering 12 states of the country with two states being randomly selected from each geopolitical zone. High-throughput Roche electrochemiluminescence immunoassay system (Elecsys Anti-SARS-COV-1 Cobas) was used for qualitative and quantitative detection of antibodies to SARS-COV-1 in human plasma. RESULTS: There was no statistically significant difference between the proportions with seropositivity for both the vaccinated and the unvaccinated (P = 0.95). The nucleocapsid antibody (anti-Nc) titres were similar in both the vaccinated and the unvaccinated, whereas the Spike protein antibody (anti-S) titres were significantly higher amongst the vaccinated than amongst the unvaccinated. Antibody levels in subjects who received different vaccines were compared to provide information for policy. CONCLUSION: While only 45.9% of the subjects were reported to have been vaccinated, 98.7% of the subjects had had contact with the SARS-COV-1 as evidenced by the presence of nucleocapsid (NC) antibodies in their plasma. The 1.3% who had not been exposed to the virus, had spike protein antibodies which most likely resulted from vaccination in the absence of NC antibodies. Successive vaccination and booster doses either through heterogeneous or homologous vaccines increased antibody titres, and this stimulation of immune memory may offer greater protection against coronavirus disease 2019.

Knowledge and Willingness to Utilize Hepatitis B Preventive Measures among Pregnant Women in Ado-Ekiti, Southwest, Nigeria.

Introduction: Mother-to-child transmission remains an important mode of transmission of hepatitis B infection particularly in endemic areas. The knowledge and practices of pregnant women about mother-to-child transmission (MTCT) of hepatitis B virus (HBV) may influence the uptake of strategies to reduce mother-to-child transmission of infection. Objectives: This study assessed the knowledge and willingness to uptake hepatitis B virus infection preventive services among pregnant women in Ado-Ekiti, Nigeria. Methods: This was a cross-sectional study that involved 373 pregnant women at the Ekiti State University Teaching Hospital (EKSUTH) and Maternal Child Specialist Clinics, Ado-Ekiti, Nigeria. A structured questionnaire was used to assess their knowledge, practices, and perceptions about MTCT of hepatitis B infection. Results: Only 52.5% (196) of the respondents had good knowledge, although the majority 290 (77.7%) had heard of hepatitis B infection prior to the survey. Only 147 (39.4%) of the respondents had ever had hepatitis B screening. More persons with professional jobs had good knowledge about hepatitis B infection compared with other occupations (p < 0.001). However, more respondents aged 30-34 years had poor knowledge about hepatitis B infection compared with other age groups (p = 0.045). Respondents with good knowledge about hepatitis B infection were willing to uptake hepatitis B infection prevention services (p < 0.001). Conclusion: This study showed that respondents with professional jobs had good knowledge about hepatitis B infection and those who had good knowledge about the infection were willing to utilize hepatitis B preventive measures. Awareness of MTCT of HBV did not translate into good practice as only few respondents had screened for hepatitis B. There is a need to intensify education about modes of transmission of hepatitis B infection with an emphasis on promoting good preventive practices.

Human milk banking acceptability among pregnant and nursing mothers in Southwest Nigeria.

Background: Human milk bank is a sustainable source of donor human milk (DHM) which is an acceptable alternative to the mother's milk and it is not routinely available in Nigeria, a multi-ethnically diverse country.The study aimed to assess the willingness to donate or accept human milk among pregnant women and mothers attending the antenatal, immunization, outpatient, under-five, and neonatal follow-up clinics in selected health facilities in Ekiti State, Southwest Nigeria. Study Design and Methods: A descriptive cross-sectional, mixed methods study design was used to collect data in selected health facilities in Ekiti State. Questionnaires and focus group discussions were used to collect quantitative and qualitative data respectively while data analysis was done using the IBM® Statistical Package for Social Science SPSS version 26® and thematic analysis respectively. Results: Of the 798 respondents, 529 (66.3%) and 626 (78.4%) did not know about wet nursing or human milk banking (HMB) respectively and 139 (17.4%) were willing to donate their breastmilk for a stipend. In the focus group discussion, 50% had heard about wet nursing but none heard about HMB. Maternal educational level had a significant impact on their willingness to donate or accept DHM (p < 0.00). Wholesomeness, cultural, and religious biases were major reasons affecting HMB acceptability. Conclusions: Awareness and perception of HMB are poor. Appropriate information, education, and counselling on HMB are needed to drive the adoption and establishment of HMB in Nigeria.

Pattern of admissions and outcome in the children emergency department of a tertiary health institution in Southwestern Nigeria: A four-year review.

Introduction: Pediatrics and adolescents are susceptible to illnesses that often necessitate emergency attention. Morbidity and mortality from illnesses in these ages have attracted much interest globally, particularly in Africa. Knowledge of pattern and outcomes of admissions may guide policy and interventions especially in resource constrained settings. The study aimed to determine the pattern of admissions, outcomes and seasonal variations of conditions that presented at the children emergency of a tertiary health institution over a four-year period. Methods: A retrospective descriptive study of children emergency admissions from January 2016 to December 2019. Information obtained included age, diagnosis, month and year of admission, and outcome. Descriptive statistics were used to describe the demographic characteristics and Chi-squared test to assess their associations with the diagnoses made. Results: There were 3,223 admissions. There were more males (1866; 57.9%) and more toddlers (1181; 36.6%). The highest number of admissions were observed in the year 2018 (951; 29.6%) and during the wet season (1962; 60.9%). There was an overall mortality rate of 7%; complicated malaria, gastroenteritis and meningitis were the leading causes of death. Malaria (χ2 = 135.522, p value < 0.001), and gastroenteritis (χ2 = 130.883, p value < 0.001) were predominant among the toddlers while sepsis (χ2 = 71.530, p value < 0.001) and pneumonia (χ2 = 133.739, p value < 0.001) were more among the infants. Typhoid enteritis (χ2 = 26.629, p value < 0.001) and HIV (χ2 = 16.419, p value = 0.012) were commoner among the early adolescents. Conclusion: The major causes of death in the study area are preventable with more of these amongst the children under the age of 5 years. There are seasonal and age-related patterns to admissions and the need for policy formulations and emergency preparations to be tailored towards these observed patterns through the year.

Households Health Care Financing Methods: Social Status Differences, Economic Implications and Clinical Outcomes Among Patients Admitted in a Pediatric Emergency Unit of a Tertiary Hospital in South West Nigeria.

Background. The affordability of health care services by households within a country is determined by the health care financing methods used by her citizens. In accordance with World Health Organization (WHO), health services must be delivered equitably and without imposing financial hardship on the citizens. Aim. This study aimed to determine the pattern of households health care financing method and relate it to the social-background, economic implication and clinical outcome of care in pediatric emergency situations. Method: It is a cross-sectional descriptive study. Result. 210 children from different households were recruited. Majority (75.9%) of the children were aged 0 to 5 years, males (61.2%) and belonged to the low socio-economic status (95.7%). The overall median (IQR) cost of care, income and percentage of income spent on care were ₦10 700 (₦7580-₦19 700), ₦ 65000(₦38000-₦110 000) and 17.6% (7.1%-39.7%) respectively. Though 70 (34.8%) of the respondents were aware of health insurance scheme, only 12.8% were enrolled. There were significant differences in the households' health care financing methods with respect to the socioeconomic status (P = .010), paternal level of education (P < .001), maternal occupation (P = .020), paternal occupation (P = .030) and distribution of income (P < .001). Catastrophic spending was experienced by 67.4% of the household, all of whom paid via out-of-pocket payment (OOPP) (P < .001), catastrophic health spending (CHS) was significantly associated with death and discharge against medical advice (DAMA) (P = .023). All cases of mortality and 93% cases of DAMA occurred with paying out of pocket (OOP) (P = .168). Conclusion. health care services were majorly paid for OOP among households in this study and CHS are high among these households. Clinical and financial outcomes were worse when health care services were paid through OOP.

Anasarca as a manifestation of childhood volvulus: Diagnostic and management challenges in an 11-year old Nigerian boy.

Background: Small intestine volvulus occurs more commonly among younger children. It often poses diagnostic challenges when it occurs in older children and adults. For good clinical outcomes, it is essential to have prompt presentation, diagnosis and early intervention. Anasarca is not a common clinical manifestation of small intestine volvulus. Case Presentation: We report this unusual presentation of small intestine volvulus in an 11-year old Nigerian boy who first presented only with anasarca. While being investigated for the cause of the anasarca, he developed features of acute abdomen thought to be spontaneous bacteria peritonitis initially. He had surgery where the diagnosis of small intestine volvulus was made. Conclusion: The diagnosis and management of both anasarca and small intestine volvulus could be fraught with challenges. It is possible that anasarca can be the first manifestation of small intestine volvulus.

Knowledge, practice and technique of facemask usage among healthcare workers in a tertiary hospital in Ado-Ekiti, Nigeria.

Introduction: Infection prevention and control remains very key to safety in healthcare settings and community. The use of personal protective equipment is now more relevant especially with the advent of COVID-19 pandemic. This study aimed to assess the knowledge, attitude, practice and technique of wearing facemask among healthcare workers at Ekiti State University Teaching Hospital, Ado-Ekiti, Nigeria. Methods: A descriptive cross-sectional questionnaire-based study explored knowledge, attitude and reported practice on the use of facemask. Also, a checklist was used to directly observe how participants put on and remove facemasks. Results: Of the 450 respondents, 316 (70.2%) had good knowledge score. Only 255 (56.7%) had good attitude and barely half of the respondents 229 (50.9%) had good practice. However, the majority of those who were observed had good technique of wearing facemask 387 (86.4%). Also, 188 (41.8%) of the healthcare workers believed that face shield alone offers adequate protection against transmission of COVID-19. Conclusions: Our finding suggests that knowledge does not translate to good practice. Furthermore, the fact that two out of every five healthcare workers held erroneous belief about face shield, and another one-third had poor knowledge points to the need for training and retraining of healthcare workers with the aim of reinforcing the need for consistent and correct use of facemasks. This should have a salubrious effect on the community knowledge of COVID-19 prevention as healthcare workers are believed to be the most common sources of health information to the lay public.

Adherence to WHO Criteria on Drug Promotion Literature: An Exploratory Study From a Tertiary Healthcare Facility in South-West Nigeria.

Introduction: In many low and middle-income countries (LMIC), drug promotional literature (DPL) remains one of the main sources of drug information for physicians. Studies conducted in many LMICs showed poor compliance to the WHO guidelines for ethical drug promotion especially in the area of information about excipients, adverse drug reactions, drug-drug interactions and contra-indications. These inadequacies in the information provided may mislead the prescriber with potential adverse consequences among patients using the medicines. Nigeria has a big pharmaceutical sector which is poorly regulated and we hypothesize that such unethical drug promotional practices may exist. This study therefore set out to assess compliance to the WHO ethical drug promotion (using DPL) at the Ekiti State University Teaching Hospital (EKSUTH), Ado-Ekiti, South-West Nigeria. Methodology: This was a descriptive cross-sectional study conducted in several specialist clinics of EKSUTH, Ado-Ekiti. Printed DPLs (brochures and leaflets) were collected from these clinics, collated using a pre-designed data collection form and analyzed using the WHO ethical criteria for medicinal drug promotion. Results:Two hundred seventy-five DPLs were screened A total of out of which 234 DPLs were selected after screening to after removal of duplications. Only 5 (2.1%) DPLs met all the WHO criteria. DPLs promoting antibiotics, cardiovascular drugs, and vitamins/nutritional supplements were in the majority (22.2%, 17.1%, and 11.5% respectively. Most of the DPLs had the generic (223; 95.3%) and brand (234; 100%) names, active ingredients (209; 89.3%), excipients (149; 63.7%), and indications (232; 99.1%). Information about adverse drug reactions (76; 32.5%), contra-indications (73; 31.2%), and drug interactions (46; 19.7%) was less represented. Only 59 (25.2%) DPLs had references. Fixed-dose combination drugs made up 34.6% of drugs being promoted. Conclusion:The DPLs assessed in this study had low adherence to WHO ethical drug promotion criteria especially those related to adverse drug reaction, drug interactions, and contra-indications.

Breastfeeding: Knowledge, Perception, And Intention to Practice Among Female Students of Tertiary Institutions in Ekiti, Southwest Nigeria.

INTRODUCTION: Breastfeeding is a public health practice that is critical for the survival of infants and young children. This study aimed at determining the knowledge, attitude, and future intention to breastfeed among female undergraduates in tertiary institutions in Ekiti State, Southwest Nigeria.Methodology: A prospective cross-sectional study was conducted among 1312 female students of the tertiary institutions in Ekiti State. By convenience sampling, female students were invited to participate in the study after giving verbal consent and those studying medical, nursing, and other courses allied to medicine were excluded. Internal consistency of the data obtained from this research instrument was determined using Cronbach's coefficient Alpha with a reliability value of 0.82. Data analysis was conducted using SPSS version 25. Descriptive as well as inferential statistics were computed. Results were summarized as frequencies and percentages. The differences in knowledge, attitude, and intention to practice breastfeeding as well as other responses among the participants were compared among age groups, faculties and the sources of information using Chi-square test. RESULT: Although 93% of the respondents agreed that breast milk is important for the development of the infant's brain thereby demonstrating good knowledge; 51.6% of the respondents demonstrated poor perception to breastfeeding believing breastfeeding makes the breast to sag while only 34% of the respondents indicated their intention to breastfeed their future babies. CONCLUSION: The intention to breastfeed among our study participants was poor. This study revealed the need to increase awareness about breastfeeding and its benefits among this huge population of future mothers.

Blood pressure and electrocardiographic profile of children with sickle cell anaemia in steady-state and vaso-occlusive crisis.

Objective: To compare the cardiovascular features of patients with sickle cell anaemia (SCA) in steady-state with those in vaso-occlusive crisis (VOC) at the Wesley Guild Hospital (WGH). Design: A descriptive cross-sectional, matched, case-control study among children with SCA at the WGH, a tertiary health facility in southwest Nigeria. Setting: The participants were recruited from the children's emergency unit and paediatric haematology clinic of the WGH. Participants: Consisted of 93 children with VOC (cases) and 93 age and sex-matched in steady state (controls), aged 5 - 15 years. Main outcome measures: Cardiovascular parameters, including pulse rate, blood pressure, and electrocardiographic profile, were assessed and compared using the appropriate statistical tests. Results: The mean (SD) age of the cases and controls were 8.8 (3.2) years and 9.0 (3.1) years, respectively (p= 0.106). There was no significant difference in the mean height of the groups. The mean pulse rate, diastolic, systolic, and mean arterial pressures were significantly higher in the cases than in the controls. A significantly higher proportion of the cases than the controls also had a higher frequency of heart blocks, prolonged QTc interval, ST elevation or depression, and T wave abnormality (p = 0.018, 0.039, 0.041, 0.009, respectively). The prevalence of chamber enlargements was not significantly different between the two groups. Conclusion: Cardiovascular dysfunction is worse during VOC when compared with steady state. Physicians should look for these dysfunctions in SCA children with VOC to reduce mortality from the disease. Funding: None declared.

Incidence of Catastrophic Health Expenditures Amongst Hospitalized Neonates in Ekiti, Southwest Nigeria.

Background: Neonatal illnesses require huge spending due to prolonged hospital stay. The management of these illnesses is usually financed by individual families which in most instances are living below the poverty line. This healthcare financing method can readily push families into catastrophic spending on health. Aim: To ascertain the average cost of managing common neonatal illnesses and the financial burden, it constitutes to families in Ekiti State, southwest Nigeria. Methods: We conducted a cross-sectional study on the out-of-pocket spending involved in managing neonates admitted into and discharged from the SCBU of the Ekiti State University Teaching Hospital, Ado-Ekiti, southwest Nigeria. Data collected included the monthly family income, the money spent on drugs, laboratory investigations and the hospital bill using a purposely designed structured questionnaire. Healthcare spending greater than 10% of the overall family income was described as catastrophic health spending (CHS). Results: The medical bills for most (95%) of the 119 study participants were paid through the out-of-pocket means and 81.5% of the families spent more than 10% of their monthly earnings (CHS) to settle medical bills. Close to 50% of the families belonged to the lower social economic class. The median (IQR) duration of hospital stay was 2.75 days (3.0-8.0). The median (IQR) total expenditure was N24,500.00 (N13,615.00-N41,487.50). The median (IQR) expenditure for the treatment of prematurity was highest at N55,075.00 (USD 133.10) [N27,350.00 (USD 66.10)-N105,737.50 (USD 255.53)] and more than 60.5% of the expenses was on hospital utilities and consumables. The length of hospital stay showed a robust positive correlation with the total hospital bill (r = 0.576, P < 0.001). Conclusion: Neonatal illnesses put many households at risk of catastrophic health spending. There is need for increased government investment in health and extension of the health insurance scheme to all the citizens of the country.

The voices of children and young people during COVID-19: A critical review of methods.

AIM: Critically review research methods used to elicit children and young people's views and experiences in the first year of COVID-19, using an ethical and child rights lens. METHODS: A systematic search of peer-reviewed literature on children and young people's perspectives and experiences of COVID-19. LEGEND (Let Evidence Guide Every New Decision) tools were applied to assess the quality of included studies. The critical review methodology addressed four ethical parameters: (1) Duty of care; (2) Children and young people's consent; (3) Communication of findings; and (4) Reflexivity. RESULTS: Two phases of searches identified 8131 studies; 27 studies were included for final analysis, representing 43,877 children and young people's views. Most studies were from high-income countries. Three major themes emerged: (a) Whose voices are heard; (b) How are children and young people heard; and (c) How do researchers engage in reflexivity and ethical practice? Online surveys of children and young people from middle-class backgrounds dominated the research during COVID-19. Three studies actively involved children and young people in the research process; two documented a rights-based framework. There was limited attention paid to some ethical issues, particularly the lack of inclusion of children and young people in research processes. CONCLUSION: There are equity gaps in accessing the experiences of children and young people from disadvantaged settings. Most children and young people were not involved in shaping research methods by soliciting their voices.

Use of indigenous language for clinical clerkship: a cross-sectional survey in Nigeria.

Background: Doctors' knowledge of the native language of their patients is important to effectively communicate with them. Aims: This paper aimed to explore the views and practices of medical students in Nigeria on the use of Yorùbá (an indigenous language) in their clinical clerkship. Methods: This was a cross-sectional survey of students in two medical colleges in Ekiti State, Nigeria. Data were collected using self-administered questionnaires. Results: The study included 312 medical students, 176 males and 136 females. Most students (70.8%) used Yorùbá in their clinical clerkship despite learning medicine in English. Only 16.0% of the students relied on interpreters. None of the students had had exposure to language training in the course of their medical education. Most of the students (73.7%) supported the incorporation of indigenous language training into the medical school curriculum, and agreed that teaching indigenous languages in medical school would enhance communication skills. Conclusions: Incorporation of indigenous language training into the medical school curriculum in Nigeria is recommended to help overcome language barriers in clinical practice.

Relationship between ultrasound-measured spleen, liver and anthropometry of children living in a rural community in southwest Nigeria: a cross-sectional study.

BACKGROUND: Ultrasonography is noninvasive, relatively inexpensive and useful for resource-poor settings. US spleen and liver sizes have been observed to differ among populations, so there is a need for reference values for different geographic populations. OBJECTIVE: To describe the sizes of the spleen and liver of children living in a rural community in southwest Nigeria and assess the relationship between these measurements and the children's anthropometry. MATERIALS AND METHODS: We conducted a community-based cross-sectional study among 358 apparently healthy children ages 1-14 years. We obtained the participants' weights, heights, body mass index and body surface area. They underwent US imaging to obtain longitudinal measurements of their spleen and liver. We used independent t-test to compare means, and linear regression analysis to assess relationships between continuous data. The significance level was set as P < 0.05. RESULTS: There were more girls (181; 50.6%). Most children were ages 1-5 years (172; 48.0%). The body surface area had significantly strong positive relationships with US spleen size (r = 0.769; R2 = 0.592; P < 0.0001) and US liver size (r = 0.819; R2 = 0.671; P < 0.0001) but body mass index had weak positive relationships. CONCLUSION: This study contributes to data on US spleen and liver sizes of Nigerian children. The findings buttress observations that body surface area strongly correlates with US spleen and liver measurements. It is recommended that more studies be conducted among Nigerian children to generate a robust pool of data that are useful for creating homogeneous formulae to ease interpretation of US measurements of these intraabdominal organs.

Malaria prevention practices and malaria prevalence among children living in a rural community in Southwest Nigeria.

INTRODUCTION: Living conditions in most rural African communities favour malaria transmission and threaten global eradication. Prevention strategies and interventions such as the use of bed nets have reduced the prevalence of malaria. This study described the various methods employed to prevent malaria and their effects on malaria parasite prevalence among children living in a rural community in Nigeria. METHODOLOGY: A community-based cross-sectional study conducted among 357 children aged 1-15 years, in a Nigerian rural community. Data was analyzed using SPSS version 25. Chi-squared test of association with a level of significance of p < 0.050 was used. RESULTS: Only 110 (30.8%) participants owned mosquito nets. Mostly those from the high social class (45; 40.9%) used the nets, and these were mostly 'under-five' children. Thirty-six (10.1%) were routinely given antimalarial drugs for malaria prophylaxis. Also, 102 (28.6%), 151 (42.3%), 278 (77.9%), 99 (27.7%) and 15 (5.0%) children used insecticides, local herbs, window nets, outlet door nets and mosquito repellent creams respectively. None of the methods employed to prevent malaria had statistically significant effect on malaria parasite prevalence among participants (p > 0.050). CONCLUSIONS: Malaria prevention methods were mostly practiced by participants of the high social class while children under-five considerably used mosquito nets. This study highlights the need to address the socio-demographic imbalance regarding malaria preventive measures in the community where the study was conducted. There is also a need to regulate the use of antimalarial drugs for malaria prophylaxis in the rural community. These suggest that the current malaria prevention methods in the community be reviewed.

A ten-year review of neonatal tetanus cases managed at a tertiary health facility in a resource poor setting: The trend, management challenges and outcome.

BACKGROUND: Neonatal Tetanus (NNT) is a vaccine preventable disease of public health importance. It is still being encountered in clinical practice largely in developing countries including Nigeria. NNT results from unhygienic delivery practices and some harmful traditional cord care practices. The easiest, quickest and most cost-effective preventive measure against NNT is vaccination of the pregnant women with the tetanus toxoid (TT) vaccine. The case-fatality rate from tetanus in resource-constrained settings can be close to 100% but can be reduced to 50% if access to basic medical care with adequate number of experienced staff is available. MATERIALS AND METHODS: This retrospective study reviewed the admissions into the Special Care Baby Unit (SCBU) of the Ekiti State University Teaching Hospital, Ado-Ekiti from January 2011 to December 2020. The folders were retrieved from the records department of the hospital; Information obtained from folders were entered into a designed proforma for the study. RESULTS: During the study period, NNT constituted 0.34% of all neonatal admissions with case fatality rate of 52.6%. Seven [36.8%] of the babies were delivered at Mission home/Traditional Birth Attendant's place while 5 [26.3%] were delivered in private hospitals. Cord care was with hot water compress in most of these babies16 [48.5%] while only 9% of the mothers cleaned the cord with methylated spirit. Age at presentation of less than one week was significantly associated with mortality, same with presence of autonomic dysfunction. Low family socio-economic class 5 was significantly associated with poor outcome, so also maternal age above 24 years. CONCLUSION: This study revealed that neonatal tetanus is still being seen in our clinical practice with poor outcome and the risk factors are the same as of old. Increased public health campaign, promotion of clean deliveries, safe cord care practices, affordable and accessible health care provision are recommended to combat NNT scourge.

Towards malaria control in Nigeria: implications of the malaria parasite rate and spleen rate among children living in a rural community in southwest Nigeria.

BACKGROUND: The World Health Organization prioritizes malaria surveillance for accurate tracking of progress of intervention programmes. The malaria parasite rate (PR) and spleen rate (SR) are economical surveillance tools. There has been a global decline in the burden of malaria over the last decade, but most African countries, like Nigeria, have a slow rate of decline. There is a need for adequate malaria surveillance to guide malaria control strategies and policymaking. METHODS: A community-based cross-sectional study was conducted among 363 children ages 1-15 y in rural southwest Nigeria. The participants' PR was determined by microscopy and the SR was determined by palpation and ultrasonography. The associations between PR and SR and other covariates were assessed. RESULTS: The PR was 26.7% and the SR was 12.9%. There was no significant association between PR or SR across age groups, but low social class was significantly associated with PR (55 [33.5%], p=0.004) and SR (29 [17.3%], p=0.013). The odds of having splenomegaly doubled with malaria parasitaemia (odds ratio 2.03 [95% confidence interval 1.06 to 3.88). CONCLUSIONS: The PR and SR suggest that the study area is meso-endemic. The PR in the study area was almost equal across age groups; our findings suggest there may be a need for policy review to plan malaria intervention programmes and include older children, not just children <5 y of age. Routine malaria surveillance using simple tools such as the PR and SR are necessary for reviewing malaria control programmes in the community.

Diagnostic Accuracy of HemotypeSC as a Point-of-Care Testing Device for Sickle Cell Disease: Findings from a Southwestern State in Nigeria and Implications for Patient Care in Resource-Poor Settings of sub-Saharan Africa.

This study aimed to determine the performance of a rapid, point-of-care testing device (HemotypeSC)™ for diagnosing sickle cell disease (SCD) relative to 2 commonly-used methods compared to DNA polymerase chain reaction (PCR) as the reference standard. The diagnostic performance of (HemotypeSC)™ in diagnosing SCD and determining various other Hb genotypes relative to high performance liquid chromatography (HPLC) and cellulose acetate Hb electrophoresis in alkaline buffer (CAE) was investigated among 156 participants aged 4 to 23 years in Ekiti, Southwest Nigeria. PCR was considered as the reference method/gold standard. The sensitivity and specificity for SS, SC, AS, AC, and AA genotypes by HemotypeSC and HPLC when compared with PCR, were each 100%. Similarly, their positive and negative predictive values were each 100%. However, sensitivity and specificity for identifying these Hb genotypes by CAE were 100, 100, 96.5, 0, 99.2%, and 99, 100, 92.9, 0, 91.7%. Also, CAE did not identify any of the 2 HbAC individuals that were correctly identified by PCR and both HemotypeSC, and HPLC, thus representing 100% HbAC misdiagnosis. In conclusion, this study shows that HemotypeSC has perfect concordance with PCR and 100% accuracy in diagnosing SCD in the population tested. Its ease of use, accuracy and other attributes make it suitable for use in sub-Saharan Africa for rapid determination of Hb genotypes.

Aetiologies of profound bilateral sensorineural hearing loss among children in Ekiti State, South Western Nigeria.

INTRODUCTION: a strong need exists for the knowledge of aetiologies of diseases as this will guide the clinicians on the strategies for their treatment and prevention. In this study, we determined the aetiologies of profound bilateral sensorineural hearing loss (pbSNHL) with a view to provide the relevant data needed for preventive and therapeutic intervention among children in Ekiti State, South Western Nigeria. METHODS: medical records of children with pbSNHL seen over a ten-year period were analysed. RESULTS: in all, records of 142 children with pbSNHL were analysed. The results showed spectrum of aetiologies that were similar to those reported decades ago with the 'unknown' assuming a recurring decimal. Of the known (acquired) cases, measles takes up the largest 'chunk' with a prevalence of 45.8%. Twenty-eight (32.2%) of those with febrile illnesses had treated their fever with ototoxic antibiotics. Late diagnosis was characteristic of the pbSNHL. CONCLUSION: this study shows that there hasn't been any significant shift in the common causes of pbSNHL. Of great concern is the persistence of the 'unknown' causes which assumes a recurring decimal in this and previous studies. Also worrisome is the high prevalence of measles-induced pbSNHL despite the availability of anti-measles vaccine. We therefore suggest effective immunization against measles and other vaccine-preventable causes of pbSNHL. The need for intensive research on the unknown causes of pbSNHL is hereby stressed. Also recommended is routine hearing assessment for survivors of febrile conditions so as to detect, if any, hearing loss promptly.

Determinants of Care-Seeking Practices for Children with Sickle Cell Disease in Ekiti, Southwest Nigeria.

BACKGROUND: Due to the chronic nature of sickle cell disease (SCD), affected individuals may seek help from diverse places thus raising the need to understand their health-seeking behavior (HSB) in order to design an appropriate management policy for them. AIM: The aim of this study was to evaluate the HSB among pediatric SCD patients relative to their non-SCD counterparts attending a tertiary facility in Southwest Nigeria and identified predictors of poor HSB among SCD patients. METHODS: A total of 110 children with SCD were recruited and studied for their HSPs which were compared with 110 non-SCD patients with other chronic medical conditions. Questionnaires were used to obtain self-reported information on participants' socio-demographic data and HSB. Logistic regression was used to determine the predictors of poor HSB among the SCD cohort. RESULTS: More SCD patients received treatments at private hospitals, patent medicine stores and faith-based centers compared to their non-SCD counterparts (p=0.0052; 0.006; and 0.007), respectively. No difference was observed in the patronage of traditional care centres 10 (9.1%) vs 6 (5.5%). More SCD patients 61 (55.5%) vs 35 (31.8%) exhibited poor HSB (p=0.0004). SCD patients who were not enrolled on health insurance scheme were 18 times more likely to have poor HSB (OR=18.38, 95% CI (4.41-76.57), p value= <0.0001) while absence of VOC within the preceding year reduces the risk of poor HSB by 91.5% (OR=0.085, 95% CI (0.028-0.258), p value= <0.0001). CONCLUSION: SCD patients in the study locality had poor HSB. This raises the need for their education on proper HSB. More enrollment into health insurance scheme and the prevention of VOC will lessen the burden of poor HSB. The high patronage of non-hospital care facilities in this study raises the need for stakeholders to monitor activities and train the operators at these informal care centres.
