RESUMO
BACKGROUND: Limited data exist on functional gastrointestinal disorders (FGIDs) among sub-Saharan African children. This study aimed to determine FGID prevalence and pattern among secondary school adolescents in Lagos, Nigeria. METHODS: This descriptive cross-sectional study was conducted among adolescents aged 10-18 years in Isolo, Lagos, Nigeria from December 2020 to March 2021. A multi-stage sampling technique was used to select a total of 696 students from four secondary schools. Data were collected using a specifically designed questionnaire, the ROME IV questionnaire (QPGS-IV), and analyzed using the Statistical Package for the Social Sciences (SPSS) version 24. RESULTS: The mean age of the adolescents was 13.6 ± 2.1. A total of 221 (31.8%) adolescents fulfilled the criteria for at least one of the FGIDs. The most common FGIDs were functional constipation (10.1%), functional dyspepsia (9.4%) and abdominal migraine (8.6%). There was no significant difference in the overall prevalence of FGIDs between age groups (p = 0.07) and genders (p = 0.949). However, the prevalence of FGID sub-types showed that abdominal migraine, irritable bowel syndrome and functional non-retentive fecal incontinence were significantly higher in the age group 10-12 years (p = 0.045, p = 0.029 and p = 0.027, respectively) while only functional vomiting was significantly higher in male compared to female (p = 0.038). CONCLUSION: FGIDs are common among adolescents in Lagos, Nigeria. The pattern of FGIDs shows similarities and differences with reports from other parts of the world. Healthcare workers must be aware of these disorders to provide optimal care.

Malnutrition results in a high prevalence of stunting, underweight, and micronutrient deficiencies. This study investigated the effect of a multi-nutrient fortified dairy-based drink on micronutrient status, growth, and cognitive development in malnourished [height-for-age z-score (HAZ) and/or weight-for-age z-score (WAZ) < -1 SD and >-3 SD] Nigerian toddlers (n = 184, 1-3 years). The product was provided in different daily amounts (200, 400, or 600 ml) for 6 months. At baseline and endline, venous blood and urine samples were collected to determine micronutrient status. Bodyweight, height, waist, and head circumference were measured, and corresponding Z-scores were calculated. The Bayley-III Screening Test was used to classify the cognitive development of the children. In a modified per-protocol (PP) population, the highest prevalence's of micronutrient deficiencies were found for vitamin A (35.5%) and selenium (17.9%). At endline, there were no significant improvements in iodine, zinc, vitamin B12, and folate status in any of the three groups. Regarding vitamin D status (25OHD), consumption of 600 and 400 ml resulted in an improved status as compared to baseline, and in a difference between the 600- and 200-ml groups. Consumption of 600 ml also increased vitamin A and selenium status as compared to baseline, but no differences were found between groups. Within the groups, WAZ, weight-for-height z-score (WHZ), and BMI-for-age z-score (BAZ) improved, but without differences between the groups. For HAZ, only the 600 ml group showed improvement within the group, but it was not different between groups. For the absolute weight, height, and head circumference only trends for differences between groups were indicated. Cognition results did not differ between the groups. Within groups, all showed a decline in the per cent of competent children for receptive language. To study the effects of a nutritional intervention on linear growth and cognition, a longer study duration might be necessary. Regarding the improvement of micronutrient status, 600 ml of fortified dairy-based drink seems most effective.

RESUMO
Infantile cholestasis has numerous causes and diagnosis can be difficult, especially in low-income countries where essential laboratory facilities are not readily available. This is a report of a baby who had severe conjugated neonatal hyperbilirubinaemia and deranged liver function tests, which posed a diagnostic dilemma before a diagnosis of congenital cytomegalovirus (CMV) infection was made. He was treated with Ganciclovir and responded well to treatment. He had no obvious associated neurologic manifestation of the disease and is presently been followed-up. This report highlights the challenges encountered in the diagnosis and management of the baby, as well as the favourable outcome with Ganciclovir therapy. The aim of the report is to increase the awareness of paediatricians and other stakeholders on congenital CMV infection in order to ensure early diagnosis and appropriate treatment of affected babies, with the ultimate aim of improving their prognoses and preventing the associated audiologic and cognitive sequelae.

Skin fold thickness (SFT) measurement is a reliable, cheap, simple, noninvasive method of body fat estimation at all ages including the neonatal period. Objective. To determine reference values of biceps, triceps, subscapular, and suprailiac skinfold thickness measurements in term Nigerian newborns. Method. A prospective cross-sectional study over a six-month period (Dec 2010-May 2011) was carried out on term and healthy neonates delivered between 37 and 41 weeks. The anthropometric measurements were taken within the first 48 hours of life including the skinfold thickness. The skinfold thickness measurements were taken at four sites, namely, triceps, biceps, subscapular, and suprailiac, using Harpenden skinfold calipers. The mean of two readings was recorded. Result. A total of one thousand one hundred and sixty-eight neonates were studied. The birth weight ranged between 2000 g and 5000 g with a mean birth weight of the neonates at 3259 ± 470 g. The mean birth weight of the males (3339 ± 0.45) was significantly higher than that of females (3200 ± 0.44) (p < 0.0001). Female neonates had higher mean values of triceps, subscapular, and suprailiac skinfold thickness (p < 0.001, resp.) while male neonates had higher mean value of biceps skinfold thickness (p = 0.008). Females also had higher mean values of the sum of skinfold thicknesses at all four sites and the sum at the two truncal sites at every stratified gestational age. Conclusions. The sex specific percentile chart developed for skinfold thickness measurements can be used to detect deviation from the reference population such that infants who are at risk of nutritional or health problems are identified early, and intervention is instituted promptly.
RESUMO
BACKGROUND: Prescribing medicines in an off-label manner for children with chronic conditions is sparsely documented, even more so among developing countries. This needs addressing. The objective of this research was to investigate the extent of off-label prescribing among children with epilepsy, asthma, and sickle cell anaemia in Nigeria. METHODS: Prescriptions for children ≤16 years documented in their case files that attended paediatric clinics in Lagos, Nigeria, for these three conditions between January and October 2015, were reviewed retrospectively to extract data on the medicines prescribed. British National Formulary for children and American Hospital Formulary Service Drug information were used as references. RESULTS: 477 patients received 1746 prescriptions. Off-label prescriptions were seen in 7.7% of prescriptions, related to dose (93; 68.9%), indication (22; 16.3%), and age (20; 14.8%). Nervous system (525; 30.1%) and anti-infective (441; 25.2%) medicines were the most prescribed but only 9.5% and 8.2% of the respective prescriptions were off-label. Children with epilepsy received the most number (94; 69.6%) of off-label prescriptions. The three chronic conditions did not associate significantly with the category of off-label medicine prescribed (p = 0.925). CONCLUSION: Off-label prescribing for children with epilepsy, asthma and sickle cell anaemia occurs. Encouragingly, the overall rate appears low in Nigeria.

INTRODUCTION: Growth retardation and under-nutrition are common in children with sickle cell disease (SCD). The aim of this study was to compare the head circumference (HC) of SCD children and non-SCD children and to determine the effect of malnutrition on head circumference of children with SCD. METHODS: This was a prospective case-control study conducted at the Lagos State University Teaching Hospital, Nigeria, involving SCD children (subject, n = 118) and non-SCD children (control, n = 118) matched for age, sex, and socioeconomic status. Weight, height and HC were measured using standard techniques. RESULTS: The mean ages of children with and without SCD were 7.46 ± 3.69 years and 7.01 ± 3.58 years, respectively. The HC increased significantly with age in both males and females (r = 0.75, p = < 0.001; r = 0.70, p < 0.001 respectively). There was no significant difference in HC between males and females (p > 0.05). At all ages, the mean head circumference of SCD children was not significantly (p > 0.05) different from non-SCD children. The In the age group 11-15 years, the prevalence of stunting was significantly higher among SCD children than non-SCD children. The mean HC of SCD children with stunting was significantly lower than those not stunted (51.7 vs. 53.5; P= 0.006) in age group 11.15 years. CONCLUSION: The head circumference of children with SCD is not significantly different from that of non-SCD children. Therefore, the HC chart for the general population is also applicable for monitoring head growth in children with SCD. The effect of malnutrition on head circumference of SCD children is most marked in age group 11-15 years.

BACKGROUND: Information regarding the incidence of drug-drug interactions (DDIs) and adverse drug events (ADEs) among paediatric patients in Nigeria is limited. METHODS: Prospective clinical audit among paediatric outpatients in four general hospitals in Nigeria over a 3-month period. Details of ADEs documented in case files was extracted. RESULTS: Among 1233 eligible patients, 208 (16.9%) received prescriptions with at least one potential DDI. Seven drug classes were implicated with antimalarial combination therapies predominating. Exposure mostly to a single potential DDI, commonly involved promethazine, artemether/lumefantrine, ciprofloxacin and artemether/lumefantrine. Exposure mostly to major and serious, and moderate and clinically significant, potential DDIs. Overall exposure similar across all age groups and across genders. A significant association was seen between severity of potential DDIs and age. Only 48 (23.1%) of these patients presented at follow-up clinics with only 15 reporting ADEs. CONCLUSION: There was exposure to potential DDIs in this population. However, potential DDIs were associated with only a few reported ADEs.

BACKGROUND: Upper arm composition is a reflection of body protein and calorie reserves. However, there is a paucity of data on upper arm composition of children from African countries, including Nigeria. This study aimed to determine the composition of upper arm and nutritional status of school children in Abeokuta, Nigeria and to compare with international reference standards. The sensitivity and specificity of upper arm muscle area by height (UAMAH) as a nutritional assessment tool was also determined. METHODS: Five hundred and seventy children aged 5 to 19 years were selected from seven schools using multistage random sampling. Weight, height, mid-upper arm circumference (MUAC) and triceps skin fold thickness (TSF) were measured. Body mass index, upper arm muscle area (UAMA), upper arm fat area (UAFA), fat percentage and UAMAH were derived. RESULTS: The TSF, UAFA and fat percentage were significantly higher in females than males at each age group. MUAC and UAMA were significantly higher in female children aged 10-14 years, whereas UAMA was significantly higher in male children aged 15-19 years. UAMA and UAFA of the children were lower than those of Americans but similar to those of Zimbabweans, and higher than those of Indians. The sensitivity and specificity of UAMAH for detecting wasting were 80.8% and 63.9%, respectively, whereas the corresponding values for stunting were 32.2% and 58.2%, respectively. CONCLUSIONS: The school children studied have a combination of poor calorie and protein reserve. UAMAH may be a valuable tool for complete evaluation of the nutritional status of school children.

CONTEXT AND OBJECTIVES: Adverse drug reactions (ADRs) may cause prolonged hospital admissions with high treatment costs. The burden of ADRs in children has never been evaluated in Nigeria. The incidence of pediatric ADRs and the estimated cost of treatment over an 18-month period were determined in this study. DESIGN AND SETTING: Prospective observational study on children admitted to the pediatric wards of the Lagos State University Teaching Hospital (LASUTH) in Nigeria, between July 2006 and December 2007. METHODS: Each patient was assessed for ADRs throughout admission. Medical and non-medical costs to the hospital and patient were estimated for each ADR by reviewing the medical and pharmacy bills, medical charts and diagnostic request forms and by interviewing the parents. Cost estimates were performed in 2007 naira (Nigeria currency) from the perspectives of the hospital (government), service users (patients) and society (bearers of the total costs attributable to treating ADRs). The total estimated cost was expressed in 2007 United States dollars (USD). RESULTS: Two thousand and four children were admitted during the study; 12 (0.6%) were admitted because of ADRs and 23 (1.2%) developed ADR(s) during admission. Forty ADRs were suspected in these 35 patients and involved 53 medicines. Antibiotics (50%) were the most suspected medicines. Approximately 1.83 million naira (USD 15,466.60) was expended to manage all the patients admitted due to ADRs. CONCLUSIONS: Treating pediatric ADRs was very expensive. Pediatric drug use policies in Nigeria need to be reviewed so as to discourage self-medication, polypharmacy prescription and sales of prescription medicines without prescription.

CONTEXTO E OBJETIVOS: Reações adversas a drogas (RAD) podem causar hospitalização prolongada com alto custo de tratamento. Este efeito das RAD em crianças nunca foi avaliado na Nigéria. A incidência de RAD em pediatria e o custo estimado de tratamento em um período de 18 meses foram determinadas neste estudo. DESENHO E LOCAL: Estudo prospectivo observacional de crianças admitidas nas unidades pediátricas do Hospital Universitário do Estado de Lagos (LASUTH) na Nigéria, entre julho de 2006 e dezembro de 2007. MÉTODOS: Cada paciente foi avaliado para RAD durante a admissão. Os custos médicos e não médicos para o hospital e para o paciente foram estimados para cada RAD pela revisão das contas médicas e da farmácia, pelos registros médicos, pelos exames necessários para diagnóstico e pelas entrevistas com os pais. Os custos foram estimados em nairas (moeda nigeriana) de 2007 a partir das perspectivas do hospital (governo), dos usuários de serviços (pacientes) e da sociedade (portadores dos custos totais atribuídos ao tratamento de RAD). A estimativa de custo total foi apresentada em dólares americanos (US) de 2007. RESULTADOS: Duas mil e quatro crianças foram admitidas durante este estudo; 12 (0,6 por cento) foram admitidas devido a RAD e 23 (1.2 por cento) desenvolveram RAD durante admissão. Quarenta RAD foram suspeitadas nesses 35 pacientes e envolveram 53 medicamentos. Antibióticos (50 por cento) foram as drogas mais suspeitas. Aproximadamente 1.83 milhões de nairas (US 15,466.60) foram gastos para cuidar de todos os pacientes admitidos por RAD. CONCLUSÕES: O tratamento das RAD pediátricas foi bastante caro. As políticas de uso de drogas em pediatria na Nigéria devem ser revistas para desencorajar a auto-medicação, a prescrição de polifarmácia e a venda de medicamentos de prescrição sem prescrição.
