Improving knowledge about breast cancer and breast self examination in female Nigerian adolescents using peer education: a pre-post interventional study.

BACKGROUND: Prevention of BC of which the cornerstone is creating awareness and early detection is important in adolescents and young women because of their worse outcomes. Early detection strategies such as mammography are currently beyond the reach of most women in sub-Saharan Africa.. Lack of awareness and late presentation contribute to the poor outcomes. Awareness creation among adolescents may result in modification of some risk factors for BC with adoption of healthy life styles including accessing early detection activities. This study determined the effect of peer education as a strategy to create awareness on BC and breast self examination (BSE) among in-school female adolescents in Benin City. METHODS: This was a pre-post interventional study carried out in October -December 2016 on female students of four secondary schools in Benin City. Pre-peer training, using a pre-tested self-administered questionnaire, knowledge about BC and BSE was assessed in about 30% of each school population. This was followed by training of 124 students selected from the schools (one student per class) as peer trainers. The peer trainers provided training on BC and BSE (the intervention) for their classmates. Within two weeks of peer training knowledge about BC and BSE was reassessed in 30% of each school population. Selection of students for assessment pre and post intervention was by systematic sampling. Correct knowledge was scored and presented as percentages. Chi square test, student t test and ANOVA were used to assess associations and test differences with level of significance set at p < 0.05. RESULTS: There were 1337 and 1201 students who responded to the pre and post-training questionnaires respectively. The mean BC knowledge score (20.61 ± 13.4) prior to training was low and it statistically significantly improved to 55.93 ± 10.86 following training p < 0.0001 Following peer training, statistically significant improvement (p 0.037- < 0.001) occurred in most knowledge domains apart from symptomatology. Pre-peer training 906(67.8%) students knew about BSE but only 67(4.8%). Significantly more students 1134(94.7%) knew about BSE following peer training. CONCLUSIONS: Peer education strategy can be used to improve BC and BSE knowledge in adolescents. This strategy is low cost and could be very useful in low resource settings.

An Audit of Tuberculin Skin Testing among Nigerian Children in a Tertiary Health Facility in Benin City, Nigeria.

Background: This study objective was to describe the indications for the use of Tuberculin Skin Testing (TST) and the results in order to provide information that may be useful in defining the role of TST in the investigation and control of childhood tuberculosis. Methodology: Through a Prospective cross-sectional study an audit of TSTs carried out over a one year period (2015-2016)in a tertiary hospital was done. The indications for the TST were extracted as well as the TST readings. Results: Of the 1276 TST requests, 279(21.9%) were for children. Majority 112(40.1%) of the tests were carried out to investigate suspected cases of tuberculosis. The TST readings ranged between 0 and 20mm. Up to 68.2% (176) were negative (0-4mm). Majority 13(41.9%) of those with positive results (>10mm) were being investigated for tuberculosis. Of those diagnosed with tuberculosis 50% had a positive result. Conclusion: TST is useful in providing supportive evidence for a diagnosis of tuberculosis. It is also useful in identifying children at school entry who are infected and may benefit from prophylaxis.

Assessment of Use of National Guidelines for Malaria Case Management among Pediatric Resident Doctors Attending an Update Course in Benin City, Nigeria.

INTRODUCTION: The National Malaria Guideline is a veritable tool for appropriate case management of malaria. Whether the pediatric residents who are the primary caregivers of children know and make use of this guideline in their routine practice is not yet assessed. AIM: The aim of the study is to assess the awareness of the Nigerian pediatric residents of the national guidelines for malaria case management (including antimalarial prescription for uncomplicated and severe malaria). SETTINGS AND DESIGN: The descriptive study carried out during the 2017 National Postgraduate Medical College of Nigeria, Faculty of Paediatrics Update Course in Benin City. SUBJECTS AND METHODS: Data were obtained using a self-administered questionnaire which was given to all pediatric residents who participated at the update course and who had given written informed consent. STATISTICAL ANALYSIS USED: The statistical analysis was done using the Statistical Package for the Social Sciences version 16.0 (Inc., Chicago, Illinois, USA). RESULTS: Of the 108 participants whose questionnaires were analyzed, 75.0% were Part 1 candidates and 25.0% Part 2 candidates; mean age 34.0 ± 4.5 years (range 26-51 years) and 42 (39.0%) males while 66 (61.0%) were female. Ninety-four (87.0%) were aware of the current national guidelines for management of malaria and 45 (41.7%) had read the guidelines. Correctness of prescription was obtained from 39 (36.0%) respondents in uncomplicated malaria cases and 44 (40.7%) in severe malaria cases. This finding did not significantly associate with the years of practice, level of practice, practicing institutions, awareness, and reading of the national guideline. CONCLUSIONS: Most pediatric residents have not read nor use the national guidelines for management of malaria which reflected in poor prescription pattern of antimalarial drugs in routine practice.

Haematological Parameters and Spleen Rate of Asymptomatic and Malaria Negative Children in Edo South District, Nigeria.

Background: Malaria is commonly associated with alteration in haematologic cells of infected individuals in both the acute uncomplicated and severe phases. Whether this alteration occurs in the asymptomatic phase of the disease is still being investigated. Objectives: To examine the haematocrit, thrombocytes, and monocytes levels of children with asymptomatic malaria compared with age/sex-matched controls who are malaria parasite negative and living in a stable malaria endemic region. It also set out to identify spleen rate of the children and to compare it with that observed in malaria negative controls. Methods: One hundred well-nourished children 2-9 years old with asymptomatic malaria parasitaemia and 100 age- and sex-matched malaria negative controls were recruited by multi-stage sampling from schools in a malaria endemic region of Nigeria. Malaria diagnosis was by microscopy, and each haematologic parameter was analysed following standard protocols. Results: Mean (±) monocyte count of 2.25 ± 0.9 × 109 cells/L observed in asymptomatic malaria children was significantly higher than 1.34 ± 0.5 × 109 cells/L observed in those with no malaria (p = 0.00). Mean (±) thrombocyte count was significantly lower (asymptomatic 203.64 ± 45.90 × 109 cells/L Vs no malaria 230.91 ± 57.40 × 109 cells/L) (p = 0.00). Spleen rate in the children was 15.5%. Presence of splenomegaly was not statistically significantly fewer in children with asymptomatic malaria parasitaemia (ASMP) (14/31) when compared to those who were malaria parasite negative (17/31) (χ2 = 0.34, p = 0.57). Similarly, there was no significant difference in the mean [±] spleen length of children with ASMP (n = 14; 2.86 ± 0.9 cm) and those who were malaria negative (n = 17; 2.53 ± 0.6 cm) (t = 1.22, p = 0.23). Conclusion: Thrombocytopaenia and monocytosis could be pointers to malaria parasitaemia in asymptomatic phase in a stable malaria region.

Effect of health seeking behaviour of caregivers on severe malaria outcome in under-fives seen in a tertiary health institution in Nigeria.

BACKGROUND: Recognition of the symptoms and seeking prompt treatment in a health facility is a major means of reducing morbidity and prevention of mortality from severe malaria in under-fives. OBJECTIVES: To document the effect of health-seeking behaviour of caregivers and severe malaria outcome in underfives seen in a tertiary health institution in Nigeria. DESIGN: A descriptive cross-sectional study carried out from July 2012 - June 2013. Data were obtained using a researcher-administered questionnaire. SUBJECTS: Caregivers and children (6 - 59 months) who presented with features of severe malaria according to World Health Organization criteria. RESULTS: Of the 120 caregivers mean [SD] age (31.4 [7.0] years) /child pairs (24 [14.7] months), 35 (29%) caregivers had appropriate health-seeking behaviour. The commonest place visited for initial healthcare before presentation was the patent medicine vendors by 87 (73%) caregivers. Seventy-seven per cent of caregivers who did not have appropriate health-seeking behaviour were from the lower family social class (p = 0.03). Caregivers whose children presented with severe anaemia were significantly more likely to have appropriate health-seeking behaviour (p =0.00). The mortality rate of severe malaria was 15 per 1000; of which 94% were children whose caregivers did not have appropriate health-seeking behaviour. Age younger than 2 years (p = 0.02), cerebral malaria (p = 0.01) and jaundice (p = 0.03) significantly predicted mortality in the children irrespective of the caregivers' health-seeking behaviour status. CONCLUSION: Less than a third of the caregivers had appropriate health-seeking behaviour for their under-fives with severe malaria, and the majority of these were from the lower family social class. Cerebral malaria and jaundice significantly predicted mortality in children with severe malaria irrespective of caregivers' health-seeking behaviour status. FUNDING: The study was self-sponsored by the authors.

A Study on Childhood Epilepsy among Traders in Benin City Nigeria.

BACKGROUND: Epilepsy is a serious childhood disease associated with stigmatization in the community. Despite the deleterious effect of the disease on childhood brain growth and development, the disease is treatable. OBJECTIVE: The aim of this study is to document the knowledge of childhood epilepsy by community members using traders (market women and men in a popular market in Benin City, Nigeria) as a case study. METHODOLOGY: This was a descriptive cross-sectional study carried out in April 2018. Data collection was by researcher-administered questionnaire. The respondents were traders (women and men) in Edaiken market Benin City Nigeria who were recruited consecutively during the period of the study. The analysis was performed using the Statistical Package for the Social Sciences version 21, and the level of statistical significance of variables was set at 95% confidence level and P < 0.05. RESULTS: Of the 500 respondents, 47 (9.4%) males and 453 (90.6%) females; mean age (standard deviation) was 35.3 ± 9.4 years. Total knowledge score of childhood epilepsy in this study was 27.6%. Only 116 (23.2%) study participants gave correctly a description of epileptic fits in a child. Although majority 71.0% said that epilepsy has the medical cure, none was able to mention any known drugs for the treatment of epilepsy and 72.6% said that they would use traditional remedies. CONCLUSION: The overall observed knowledge score of childhood epilepsy was low. Although most respondents stated that epilepsy has medical cure, majority preferred the traditional options for treatment. These findings, therefore, highlighted the need to enlighten the public about childhood epilepsy and its medical treatment options.

Effect of Peer Education on Knowledge of Human Papilloma Virus and Cervical Cancer among Female Adolescent Students in Benin City, Nigeria.

INTRODUCTION: It is well documented that Human Papilloma Virus (HPV) is the cause of cervical cancer which is a major cause of morbidity and mortality especially in low- and middle-income countries. Vaccines against HPV are available. In developed countries where the vaccines have been deployed, lack of information among the target population (adolescents) is a major contributor to suboptimal uptake. In Nigeria, the vaccine is yet to be provided in the national programme on immunization, which is free, but it is available for a fee. In this study we determined the effect of peer education on the knowledge of female adolescents about HPV, cervical cancer, its treatment and prevention. METHODS: This was an intervention study. The knowledge and awareness of female students of four secondary schools were assessed using a pre-tested self-administered questionnaire prior to the training of some of the students (peers). The trained students delivered messages on cervical cancer and HPV using fliers containing key information (peer training) to their school mates in formal delivery in a class setting. The knowledge and awareness of students, post-peer training, was then assessed. RESULTS: There were 1337 students who responded to the baseline questionnaire while 1201 responded to the post-peer training questionnaire. Awareness of cervical cancer, knowledge of risk factors and cause of cervical cancer was low prior to the peer training. There was statistically significant improvement in awareness about cervical cancer and in the knowledge domains following peer training. Mean knowledge score prior to training was 12.94 ± 9.23 and this increased significantly to 53.74 ± 10.69 following peer training p < 0.0001. CONCLUSION: Peer training is effective in improving knowledge and awareness of secondary school students about HPV and cervical cancer.

Comparison of adverse events following pentavalent and diphtheria-tetanus-pertussis vaccines among Nigerian children.

INTRODUCTION: Adverse events following immunization (AEFI) may follow the use of any vaccine. There is thus a need for documentation of the types and prevalence of AEFIs for each vaccine and early identification of new events or those occurring at rates higher than expected. When one vaccine replaces another, it is important to document the safety of the new vaccine as well as compare to that of the old. In this study, we aimed to document the AEFIs following the use of pentavalent vaccine recently introduced into the National Programme on Immunization and compare with those of diphtheria-tetanus-pertussis (DTwP) vaccine which it replaced. METHODS: This was a retrospective cohort study on infants with at least 2 immunization visits who commenced immunization between June 2011 and May 2013 at the Child Welfare Clinic of Institute of Child Health, University of Benin, Nigeria. At every visit for immunization, the caregiver is asked about any reaction that followed the previous immunization, and this is documented in immunization registers which data were reviewed for this study. RESULTS: There were 2475 doses of DTwP and pentavalent vaccines administered to 946 children. Adverse events following immunizations were reported following 487 (19.7%) doses. The prevalence of AEFIs following pentavalent vaccine (22.1%) was significantly higher than that following DTwP (13.5%) P < .0001. Significantly more AEFIs followed the first dose of either vaccine compared to subsequent doses P < .0001. The commonest AEFI reported for either vaccine was fever. CONCLUSION: Adverse events following immunization following pentavalent vaccine although higher than that following DTwP was within expected levels.

Impact of home-based management on malaria outcome in under-fives presenting in a tertiary health institution in Nigeria.

BACKGROUND: Home-based management of malaria involves prompt delivery of effective malaria treatment at the community by untrained caregiver. The aim of this study was to document home-based treatment of suspected malaria by non-medical caregivers and to identify its health impact on malaria outcome (severe malaria prevalence, parasite load and mortality) in children (6-59 months). METHODS: A descriptive cross-sectional study carried out from June 2012-July 2013. Data was obtained by researcher-administered questionnaire and malaria was confirmed in each child by microscopy. Analysis was by Statistical Package for Scientific Solutions version 16. RESULTS: Of the 290 caregivers (31.2 ± 6.1 years)/child (21.3 ± 14.4 months) pairs recruited, 222 (76.6%) caregivers managed malaria at home before presenting their children to hospital. Majority (99.0%) practiced inappropriate home-based malaria treatment. While only 35 (15.8%) caregivers used the recommended artemisinin-based combination therapy, most others used paracetamol either solely or in combination with anti-malarial monotherapy [153 (69.0%)]. There was no significant difference in mean [±] parasites count (2055.71 ± 1655.06/µL) of children who received home-based treatment and those who did not (2405.27 ± 1905.77/µL) (t = 1.02, p = 0.31). Prevalence of severe malaria in this study was 111 (38.3%), which was statistically significantly higher in children who received home-based malaria treatment [90.0%] (χ2 = 18.4, OR 4.2, p = 0.00). The mortality rate was 62 per 1000 and all the children that died received home-based treatment (p < 0.001). While low socio-economic class was the significant predictor of prevalence of severe malaria (ß = 0.90, OR 2.5, p = 0.00), late presentation significantly predicted mortality (ß = 1.87, OR 6.5, p = 0.02). CONCLUSIONS: The expected benefits of home-based management of malaria in under-fives were undermined by inappropriate treatment practices by the caregivers leading to high incidence of severe malaria and mortality.

Effect of introduction of pentavalent vaccine as replacement for Diphtheria-Tetanus-Pertussis and Hepatitis B vaccines on vaccination uptake in a health facility in Nigeria.

BACKGROUND: The introduction of a new vaccine into an immunization programme may affect the immunization system negatively or positively. The aim of this study is to determine the effect of the introduction of the pentavalent vaccine as replacement for DTP and Hepatitis B vaccines on timeliness, completion of the schedule and dropout rates among children attending a health facility. METHODOLOGY: This was a retrospective cohort study which involved extracting immunization records of children attending the Institute of Child Health Child Welfare Clinic between June 2011 and May 2013. Pentavalent vaccine was introduced as a replacement for DTP and Hepatitis B vaccines in June 2012. The uptake, timeliness and dropout rates of different vaccines in the immunization schedule were determined for children who commenced immunization in the pre, peri and post introduction phases. RESULTS: A total of 1110 children were studied - 190, 410 and 510 who commenced vaccination in the pre, peri and post introduction phases of the pentavalent vaccine respectively. Uptake was significantly higher for all vaccines in the post introduction phase compared to pre and peri introduction phases (p<0.001). Completion of the immunization schedule by 60.2% of the children who commenced vaccination in the post introduction phase was higher than the 31.6% and 41.7% for the pre and peri introduction phases respectively (p<0.001). Significantly more visits were required to complete the schedule in the peri introduction phase compared to the pre and post introduction phases p<0.001. Delay in receipt of the three doses of DTP/PENTA was significantly longer in the peri introduction phase compared to pre and post introduction phases. CONCLUSION: The introduction of pentavalent vaccine significantly improved uptake of vaccines and completion of the schedule but resulted in prolonged delay in receipt of vaccines during the introduction period.

Blood transfusion services for patients with sickle cell disease in Nigeria.

BACKGROUND: Safe, timely red blood cell transfusion saves lives and chronic transfusion therapy (CTT) prevents or limits morbidities such as stroke, therefore improving quality of life of patients with sickle cell disease (SCD). METHODS: This questionnaire-based study assessed the ability of sickle cell centers in Nigeria to provide safe blood to patients with SCD between March and August 2014. RESULTS: Out of the 73 hospitals contacted, responses were obtained from 31. Twenty four (78%) hospitals were unable to transfuse patients regularly due to blood scarcity. Packed red blood cells were available in 14 (45%), while only one provided leukocyte-depletion. Most centers assessed donor risk and screened for HIV in 30 (97%), hepatitis B in 31(100%) and hepatitis C in 27 (87%) hospitals. Extended phenotyping and alloantibody screening were not available in any center. A quarter of the hospitals could monitor iron overload, but only using serum ferritin. Access to iron chelators was limited and expensive. Seventeen (55%) tertiary hospitals offered CTT by top-up or manual exchange transfusion; previous stroke was the most common indication. CONCLUSION: Current efforts of Nigerian public hospitals to provide safe blood and CTT fall short of best practice. Provision of apheresis machines, improvement of voluntary non-remunerated donor drive, screening for red cell antigens and antibodies, and availability of iron chelators would significantly improve SCD care in Nigeria.

Characteristic of Monosymptomatic and Nonmonosymptomatic Childhood Nocturnal Enuresis in Benin City; Nigeria

Background. In recent years; nocturnal enuresis (NE) has been classified into monosymptomatic nocturnal enuresis (MNE) and nonmonosymptomatic nocturnal enuresis (NMNE) on the basis of the absence or presence of daytime voiding symptoms. Identifying clinical features that differentiate MNE from NMNE would aid in quick diagnosis; which would foster the introduction of early and appropriate therapeutic care options.Objective. To identify distinguishing characteristics of MNE and NMNE in Nigerian children.Methods. The parents of children in public primary and secondary schools in Egor local government area; Edo State; were interviewed using a semi-structured questionnaire.Results. The total studied population included 1 221 parent/child pairs. Of the children studied; 228 were enuretic. There were 149 (65.4%) MNE and 79 (34.6%) NMNE children. Enuretic children with a history of multiple wetting per night or whose parents observed difficulty awakening them from sleep were significantly more likely to be in the NMNE group.Conclusion. MNE is twice as common as NMNE and the main distinguishing features between the two groups of enuretic children are multiple wetting at night and difficulty awakening the child from sleep. These were significantly more commonly observed among the NMNE group of children

The diagnostic value of both troponin T and creatinine kinase isoenzyme (CK-MB) in detecting combined renal and myocardial injuries in asphyxiated infants.

BACKGROUND: Troponin T (cTnT) and Creatinine Kinase Isoenzyme (CK-MB) are both markers of myocardial injuries. However, CK-MB is also elevated in acute kidney injury. OBJECTIVE: The diagnostic value of both cTnT and cardiac CK-MB in combined myocardial and acute kidney injuries (AKI) in asphyxiated neonates was evaluated. METHOD: 40 asphyxiated infants and 40 non-asphyxiated controls were consecutively recruited. Serum levels of cTnT, CK-MB and creatinine were measured. Myocardial injury and AKI were defined as cTnT >95th percentile of the control and serum creatinine >1.0 mg/dl respectively. RESULTS: Of the 40 subjects, 9 (22.50%), 8 (20.00%) and 4 (10.00%) had myocardial injury, AKI and combined AKI and myocardial injuries respectively. The mean cTnT and CK-MB values were highest in infants with combined AKI and myocardial injuries. The Mean cTnT in infants with AKI, myocardial injury and combined AKI and myocardial injuries were 0.010±0.0007 ng/ml, 0.067±0.040 ng/ml and 0.084±0.067 ng/ml respectively, p = 0.006. The mean CK-MB in infants with AKI, myocardial injury and combined AKI and myocardial injuries were 2.78±0.22 ng/ml, 1.28±0.11 ng/ml and 4.58±0.52 ng/ml respectively, p = <0.0001. CONCLUSION: In severe perinatal asphyxia, renal and myocardial injuries could co-exist. Elevated cTnT signifies the presence of myocardial injury. Elevated CK-MB indicates either myocardial injury, AKI or both. Therefore renal injury should be excluded in asphyxiated infants with elevated CK-MB.

Asthma management by medical practitioners: the situation in a developing country.

BACKGROUND: Asthma is a common chronic disease worldwide and is responsible for considerable morbidity, socioeconomic burden, and depletion of health resources. Clinically, diagnosis of asthma is based on information obtained from symptom questionnaires, physical examination and demonstration of variable airflow obstruction. Proper diagnosis of asthma is mandatory in clinical practice in order to avoid undue use of potentially toxic asthma medications and prevent unwarranted social stigmatization. This study aimed to determine how medical practitioners in Nigeria diagnose asthma and use asthma medications during asthma exacerbation and the follow-up period. METHODS: A semi-structured self-administered questionnaire on asthma management was distributed to medical practitioners attending the annual scientific meeting/update course in August, 2009. Forty-nine practice centers in the 6 geopolitical zones in Nigeria were included in this survey. RESULTS: Totally 131 medical practitioners (80 males, 51 females) completed the questionnaire. Post National Youth Service Corp practice (mean ± SD) was 9.95±7.78 years, ranging from 2 to 39 years. The practice centers of respondents included university teaching hospitals (65.6%), state specialist hospitals (17.6%), private hospitals (10.7%), and missionary hospitals (6.l%). Respondents' assessment of burden of asthma was high (30.5%), moderate (63.4%) and low (6.1%). Asthma diagnosis was made by various methods including: symptoms only (35.9%), health personnels (32.3%), mother/self evaluation (20.3%), and use of spirometry/peak expiratory flow rate (11.5%). Thus inappropriate asthma diagnosis could have been practiced by 116 (88.5%) medical practitioners. CONCLUSION: The study revealed inadequate knowledge of asthma diagnosis and drug management of asthma by medical practitioners in Nigeria.
