Data obtained included age, sex, presenting features, primary diagnosis, treatment modalities, duration ofhospital stay and outcomes.Results: A total of 2226 children were admitted over the study period with 67 children diagnosed with heart failure giving a prevalence rate of 3%  although only 47 case notes could be retrieved giving a case retrieval rate of 70%. There were 26 (55.3%) males and 21 (44.7%) females (M:F ratio1.2: 1). Mean age of patients was 32.6 months (±52.23) with 28 (59.6%) of them being infants. Bronchopneumonia was the commonest cause of heart  failure 31(65.9%) either singly or in combination with acyanotic congenital heart disease followed by severe anaemia in 14 (29.8%). Average duration  of hospital stay was 6.9days (±5.08) and average cost of admission was N13,266. Twenty-three patients were discharged (48.9%), while 10  (21.3%) left against medical advice, 2 absconded (4.3%) while 12 (25.3%) died.Conclusion: Heart failure remains an important cause of morbidity and mortality in children in our environment arising from largely preventable  causes. Urgent steps such as patient care giver education, immunization and screening for congenital heart disease are needed to reduce its effect  on children in our environment.","PeriodicalId":19199,"journal":{"name":"Nigerian journal of paediatrics","volume":"117 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80455311","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We report an infant of a 32-year-old mother who was treated  for multi-drug resistant TB before the index pregnancy and probably had a relapse during pregnancy. The infant presented with features of sepsis at the age of ten days, but tuberculosis was only suspected when there was no clinical response to routine antibiotic therapy, and the medical  history of the mother was reviewed.

With the paradigm shift in educational models towards outcome-based education, teaching and assessment of students must be structured to attain intended learning outcome in every rotation. \u0000Objective: This study assessed the relationship between teaching methods and learners’ satisfaction. We also identified challenges to CHER posting and likely solutions. \u0000Methods: This is a descriptive cross-sectional study, using a semi-structured anonymous feedback form to elicit perception of learning objectives and adequacy of teaching methods in CHER. Adequacy of participation in emergency care was assessed on a 4-point Likert scale. Bivariate analysis for possible determinants of adequate CHER posting satisfaction on a visual analogue scale (VAS) was done. P-value < 0.05 was considered significant. \u0000Results: A total 112 medical students participated in this study; 51.8% of them knew their specific learning objectives on the first day in the unit. The participants’ grand mean score for learning satisfaction in CHER was adequate (2.65±0.24). Their preferred teaching method was Bedside Teaching/ Clerkship (3.01±0.78) but they were dissatisfied with simulations (2.29±0.91) and participation in emergency care (2.19±0.10). Participants in junior posting were more satisfied than those in senior posting (OR =3.45, 95% CI: 1.46- 8.15; p=0.005). A high workload was identified as a challenge. \u0000Conclusion: The overall clinical experience of medical student in CHER is satisfactory. Our study however, shows that there is inadequate simulation-based teaching, case presentation and participation in case management by the medical students. Curriculum reforms may be necessary to address these identified gaps and improve clinical experience of medical students in CHER.","PeriodicalId":19199,"journal":{"name":"Nigerian journal of paediatrics","volume":"51 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75830782","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Adequate nutrition is essential to the growth and development of all children, particularly in the preschool age. \u0000Methodology: This cross-sectional study was conducted in four internally displaced person (IDP) settlements and their host communities within the Abuja municipal area council between April and May 2019. Using a multistage sampling method, subjects were recruited after parents’ informed consent, from the IDP settlements and equal numbers were drawn from their host communities. The proportion of acute malnutrition using weight for height, MUAC, BMI-for-age Z scores were compared to the 2006 WHO standards. Predictors were determined by logistic regression and statistical significance was set at p less than 0.05. \u0000Results: There were 1,179 children aged six to 59 months recruited in each group. The prevalence of wasting was 7.7% (91), moderate acute malnutrition was 7.2% (85), and severe acute malnutrition was 3.1% (37) among the IDPs while they were 7.1% (84), 6.5% (77) and 2.9% (34) respectively in the host communities. The predictors for wasting in both groups were age below 24months (Adj OR, 95% CI - 3.88, 2.38 - 6.32), low birth weight (Adj OR, 95% CI – 2.70, 1.55 – 4.71) and diarrheal disease (Adj OR, 95% CI - 5.45, 2.38 - 12.44). Location was predictive only in the host communities (Adj OR, 95% CI – 2.69, 1.37 – 5.28). \u0000Conclusion and recommendation: Acute malnutrition was high among the pre-school children in this study. The nutritional needs of displaced children in the FCT should be met and their families educated on prompt recognition and treatment of diarrhoea.","PeriodicalId":19199,"journal":{"name":"Nigerian journal of paediatrics","volume":"67 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79007604","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Diagnosis of ADHD in the background of sickle cell anaemia (SCA), a haemoglobinopathy associated with neurological complications may result in significant impairment of the child into adulthood, if not detected early. In view of the fact that ADHD can be managed if diagnosed early prompted the undertaking of this study. \u0000Subjects and Methods: Study was conducted at the Paediatric Haematology Clinic of the University of Benin Teaching Hospital, Benin City. Parents of children with SCA were informed of the study and consent obtained. Demographic characteristics were recorded. Data collection instrument was the Parent Version of the National Institute for Children’s Health Quality (NICHQ) Vanderbilt ADHD Diagnostic Rating Scale (VADRS). Scoring was done for each participant using the scoring instructions for NICHQ VADRS following the DSM-IV criteria. \u0000Results: A total of 103 children with SCA participated in this study. Sixty-two (60.2%) were males while 41 (39.8%) were females. Prevalence of ADHD was 15 (14.6%) with predominantly inattentive sub-type being the commonest. Children with stroke are two times more likely to develop ADHD than those without stroke (Fisher’s exact test = 0.269, 95% CI= 0.589 to 7.558, Odds Ratio=2.55).

Such measures included social distancing and personal hygiene which could have also helped to reduce the transmission of pneumonia among other infectious diseases. \u0000Objective: To assess the effect of COVID-19 on the incidence of pneumonia in children seen at the Department of Pediatrics, of a Nigerian private University Teaching Hospital. \u0000Method: We retrospectively analyzed the data of the patients seen with pneumonia in all the Pediatric units of the Teaching Hospital from April 2019 to March 2020 (pre-pandemic period) and compared it with that of those seen during the COVID-19 pandemic from April 2020 to March 2021. \u0000Result: There was a 28% decrease in the total number of children seen in the department from 5,657 in pre-pandemic period to 4,079 in the pandemic period. There was a 17% decrease in the mean number of children seen with pneumonia monthly from 4.92 to 4.08 in the pandemic period. This is despite the relative increase in the incidence rate of pneumonia in children seen from 1.04% in the prepandemic period to 1.2% in the pandemic period. We noted more complications of pneumonia including heart failure and anaemia in the pandemic period (24.5% of cases) than in the pre-pandemic period (15.3% of cases). \u0000Conclusion: The incidence of pneumonia in children seems to have increased in the wake of the COVID 19 pandemic.","PeriodicalId":19199,"journal":{"name":"Nigerian journal of paediatrics","volume":"38 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91047466","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
