ABSTRACT
The practice of paediatric emergency medicine in Nigeria is still evolving, and laden with enormous challenges which contribute to adverse outcomes of childhood illnesses in emergency settings. Deaths from childhood illnesses presenting as emergencies contribute to overall child mortality rates in Nigeria. This narrative review discusses existing structures, organization, and practice of paediatric emergency in Nigeria. It highlights some of the challenges and suggests ways of surmounting them in order to reduce deaths in the children emergency units in Nigerian hospitals. Important aspects of this review include current capacity and need for capacity development, equipment needs for emergency care, quality of service in the context of inadequate healthcare funding and the need for improvement.

Background: Enumerating the relationship between cardiac structures, function and chamber sizes in children with sickle cell anemia would help in delineating some cardiovascular abnormalities which will aid the Pediatric cardiologist and the cardiac surgeons in a number of decision-making situations. Objectives: The objectives of this study are to assess the dimension of cardiac structures and left ventricular function in children with sickle cell anemia in steady state and controls using echocardiography. Methods: A cross-sectional prospective study that assessed cardiac structures and left ventricular function among fifty-one children with sickle cell anemia (HBSS) and compared with fifty children with HB AA type serving as controls. Results: A significant high proportion of children with sickle cell anemia had abnormal Valvar dimension and left ventricular function above two standard deviations (2-SD) from the mean of the standard population compared to the control group, showing a statistically significant difference (χ2 = 10.42, p= 0.001).All the mean annular valves diameter, left ventricular internal dimension in systole and diastole, inter-sinus distance diameter and sinu-tubular junction diameter are higher in children with sickle cell anemia than controls and this is statistically significant. (p<0.005). Conclusion: This result shows that children with sickle cell anemia have increased valvar size diameter compared with those with normal hemoglobin type. A significantly higher proportion of respondents in type SS group had abnormal left ventricular systolic and diastolic dysfunction when compared with those in type AA group.

Background: Good breastfeeding technique is important in ensuring adequate milk delivery and preventing breastfeeding problems. Exclusive breastfeeding rate is quite low, and requisite skills regarding proper positioning and attachment of an infant while breastfeeding appears lacking among mothers in Nigeria. This study was undertaken to assess breastfeeding techniques of mothers attending the well-child clinics of two tertiary hospitals in southeast Nigeria. Materials and Methods: This cross-sectional descriptive study of 396 mother and child pairs who attend the well child clinics of two tertiary hospitals in Enugu (Enugu state University Teaching Hospital and University of Nigeria Teaching Hospital) between September 2018 and February 2019. An interviewer administered, well-structured pro forma was used to collect data while mothers were observed closely as they breastfed and scored using the World Health Organization criteria. Data were analyzed using SPSS version 22. Results: Most of the mothers studied (357; 90.2%) attended ante-natal care, and 365 (92.2%) of the deliveries were assisted by a health worker. Only 194 (49%) of mothers practiced good breastfeeding techniques. Maternal age (20-30 years) (P < 0.001, odds ratio [OR] 0.464), attendance to antenatal clinic (P < 0.001; OR 8.336), health education and demonstration on breastfeeding techniques before and after delivery (P = 0.001) and maternal level of education (χ2 = 13.173, P = 0.001) but not parity (P = 0.386; OR 1.192) were significantly associated with good breastfeeding techniques. Conclusion: There are suboptimal breastfeeding techniques among mothers. Increased awareness creation and regular demonstration of breastfeeding techniques are needed.
RésuméContexte: Une bonne technique d'allaitement est importante pour assurer une livraison adéquate du lait et prévenir les problèmes d'allaitement. Exclusive le taux d'allaitement est assez faible, et les compétences requises en ce qui concerne le positionnement et l'attachement appropriés d'un nourrisson pendant l'allaitement semblent manqué chez les mères au Nigéria. Cette étude a été entreprise pour évaluer les techniques d'allaitement des mères qui fréquentent les cliniques hôpitaux tertiaires dans le sud-est du Nigeria. Matériaux et méthodes: Cette étude descriptive transversale de 396 couples de mères et d'enfants assister aux cliniques pour enfants de deux hôpitaux tertiaires à Enugu (Hôpital universitaire d'Enseignement de l'Université d'Enugu et Université du Nigeria Enseignement hôpital) entre septembre 2018 et février 2019. Un intervieweur administré, bien structuré pro forma a été utilisé pour recueillir des données les mères ont été observées de près au fur et à mesure qu'elles allaitaient et scorelaient selon les critères de l'Organisation mondiale de la santé. Les données ont été analysées à l'aide du SPSS version 22. Résultats: La plupart des mères étudiées (357; 90,2 %) soins prénatals, et 365 (92,2 %) des livraisons ont été assistées par un travailleur de la santé. Seulement 194 (49%) des mères pratiquaient de bonnes techniques d'allaitement. Âge maternel (2030 ans) (P 0,001, rapport de cotes [OR] 0.464), présence à la clinique prénatale (P 0,001; OU 8.336), éducation à la santé et démonstration sur les techniques d'allaitement avant et après (P = 0,001) et le niveau d'éducation maternel (2 = 13,173, P = 0,001) mais pas la parité (P = 0,386; OR 1.192) ont été significativement associés avec de bonnes techniques d'allaitement. Conclusion: Il existe des techniques d'allaitement sous-optimales chez les mères. Création accrue de sensibilisation et une démonstration régulière des techniques d'allaitement sont nécessaires.

Background: Snakebite and envenomation remains a public health problem with significant morbidity and mortality in children in developing countries. The World Health Organization (WHO) in 2010 developed guidelines for the prevention and management of snakebite in Africa. Aim: The aim of this study was to compare the pattern of first aid treatment among children presenting with snakebite/envenomation with the 2010 WHO guideline for the prevention and clinical management of snakebite in Africa. Patients and Methods: All children who presented with snakebite over a 7-year period in a teaching hospital in Enugu, Nigeria. The first aid treatment given to these children was obtained and was compared with the provisions of the WHO guideline for the prevention and clinical management of snakebite in Africa (2010). Data collected were analyzed using SPSS version 22. Results: Five (71.4%) of the snakebites occurred in the rainy season and in the dark involving the lower limbs in 85.7% of cases. Six (87.5%) of the patients received one form of first aid before presentation to a health facility. None received first aid interventions in line with the WHO recommendation. Topical application of herbal concoctions to the site of the bite (37.5%) was the most common intervention. One (14.3%) of the children was promptly brought to the health facility following snakebite. The interval from bite to presentation to the health facility ranged from 1 to 12 h (median 5 h: 43 min). Conclusion: Huge gaps still exist in the first aid treatment given to snakebite victims compared to the WHO guidelines.
RésuméContexte: La morsure de serpent et l'envenomation demeurent un problème de santé publique avec une morbidité et une mortalité importantes chez les enfants des pays en développement. L'Organisation mondiale de la Santé (OMS) a élaboré en 2010 des lignes directrices pour la prévention et la gestion des morsures de serpent en Afrique. Objectif: L'objectif de cette étude était de comparer le modèle de traitement des premiers soins chez les enfants présentant des morsures de serpent/envenomation avec la directive 2010 de l'OMS pour la prévention et la prise en charge clinique des morsures de serpent en Afrique. Patients et méthodes: Tous les enfants qui se sont présentés avec des morsures de serpent sur une période de 7 ans dans un hôpital d'enseignement à Enugu, Nigeria. Le traitement de premiers soins accordé à ces enfants a été obtenu et a été comparé aux dispositions de la ligne directrice de l'OMS pour la prévention et la prise en charge clinique des morsures de serpent en Afrique (2010). Les données recueillies ont été analysées à l'aide de la version 22 du SPSS. Résultats: Cinq (71.4%) des morsures de serpent se sont produites pendant la saison des pluies et dans l'obscurité impliquant les membres inférieurs dans 85,7% des cas. Six (87,5 %) des patients ont reçu une forme de premiers soins avant d'être présentés à un établissement de santé. Aucun d'entre eux n'a reçu d'interventions de premiers soins conformément à la recommandation de l'OMS. Application topique des concoctions à base de plantes sur le site de la morsure (37,5%) était l'intervention la plus courante. Un (14,3%) des enfants a été rapidement amené à l'établissement de santé à la suite d'une morsure de serpent. L'intervalle allant de la morsure à la présentation à l'établissement de santé variait de 1 à 12 h (médiane 5 h : 43 min). Conclusion: Il existe encore d'énormes lacunes dans le traitement des premiers soins accordé aux victimes de morsures de serpent par rapport aux lignes directrices de l'OMS.

BACKGROUND: The current paradigm for treating toddler's diarrhea comprises dietary modification and fluid restriction. Previous studies show that probiotics and proton-pump inhibitors (PPIs) or H2 blockers could control diarrhea associated with functional gastrointestinal disorders (FGIDs). This study aims to determine and compare the efficacy of a short course of oral ranitidine and a probiotic in the treatment of toddler's diarrhea. METHODS: This study was a parallel-group randomized controlled trial (RCT). We sequentially enrolled 40 patients who met the eligibility criteria. We randomly assigned 20 patients to the oral ranitidine group, ten patients to the probiotic group, and ten patients to the placebo group. In the oral ranitidine group, patients received oral ranitidine (3 mg/kg/day) once daily for 10 days; in the probiotic and placebo groups, they were administered 5 to 10 billion colony-forming units (CFUs) per day of lyophilized Lactobacillus rhamnosus and 50 mg of once-daily oral vitamin C tablet respectively for 10 days. Stool frequency and consistency on the 10th day of the interventions were recorded as the primary outcomes. We used the Student's t-test to determine if there were significant differences in the mean daily stool frequencies in the three intervention groups. A p-value < 0.05 was adopted as the level of statistical significance. RESULTS: In the ranitidine group, stool frequency decreased significantly from an average of five per day on the first day to an average of approximately one per day on the 10th day of intervention (t = 10.462, p < 0.001). Additionally, stool consistency normalized on the 10th day of intervention. In the probiotic group, there was a significant reduction in stool frequency from an average of five per day on the first day to four per day on the 10th day (t = 2.586, p = 0.041), although stool consistency remained loose. However, stool consistency and frequency were not significantly affected in the placebo group (t = 1.964, p = 0.072). CONCLUSION: Oral ranitidine is more effective than probiotics in reducing stool frequency and normalizing stool consistency in toddler's diarrhea. We recommend multi-center trials with appropriate study designs to confirm and validate this finding. TRIAL REGISTRATION: ISRCTN, ISRCTN10783996 . Registered 8 April 2016-Registered retrospectively.

BACKGROUND: In children particularly in the developing world, there is a tendency to downplay the role of primary hypertension in their health. In adults, a number of factors have clearly been associated with the incidence of hypertension. Knowledge of the prevalence of hypertension and its associated factors among children in our environment is important and could inform the need for lifestyle changes and routine blood pressure (BP) checks in children so as to reduce BP-related health risks. AIM: The aim of this study is to document the prevalence of hypertension and its risk factors among children in Enugu, Nigeria. MATERIALS AND METHODS: Children aged 6-17 years attending the outpatient clinic of a tertiary hospital, were enrolled for the study. Their socioeconomic status (SES), weight, height, BP, and dipstick urinalysis were measured using standardized methods. Adherence to Mediterranean diet was assessed using the Mediterranean Diet Quality Index (KIDMED). The prevalence of hypertension and the influence of these factors on their BP were analyzed. RESULTS: Forty-six (9%) of the 491 participants had hypertension. Of these 46 hypertensive children, 72% were females while a significantly higher proportion 57% (P = 0.006), were in the age group 13-17 years. While age, gender, and the presence of protein in urine were significantly associated with hypertension in these children; body mass index, diet, family history of hypertension, and SES were not. CONCLUSION: The prevalence of hypertension in children in this environment is high and appears to be increasing. There is need for routine BP and urinalysis check for all children in our clinics and wards.
ABSTRACT
AIM: The aim of this study is to determine the pattern of cancer mortality (CM) seen in the University of Port Harcourt Teaching Hospital (UPTH) which is a cancer reference center in the Niger Delta Region. METHODOLOGY: This is a 6-year retrospective study of cancer-related deaths in UPTH using patients' admission registers in all the wards and emergency units. Furthermore, the death certificates of cases were reviewed. RESULTS: Three hundred and sixteen cases of cancer-related deaths occurred, involving 174 females and 142 males, in a female-to-male sex ratio of 1.2:1. All age groups were affected, with age group 40-49 years accounting for the majority (20.6%). CM was seen in all the systems, except the central nervous system. Cancers of the gastrointestinal tract and its accessory organs (liver and gall bladder) caused most mortality (27.9%), in a female-to-male ratio of 0.8:1. The single most involved organ in CM is the female breast (20.6%), distantly followed by mortality due to prostate cancers and hematolymphoid cancers which accounted for 9.2% each. Colorectal cancers accounted for 7.3% of cancer deaths and ranked 4th. Cancers of both cervix and stomach each accounted for 5.7% of mortality. The major histologic diagnoses were carcinomas (adenocarcinoma; 36.7%, invasive ductal carcinoma; 20.3%, squamous cell carcinomas; 8.2% and hepatocellular carcinomas; 4.4%). Leukemias and lymphomas accounted for 9.2% of cases, whereas sarcomas accounted for 5.1% of cases. CONCLUSION: Infection-related and noninfection-related cancers cause most mortality in UPTH. The 5th decade was the most commonly affected, while female breast was the single most involved organ. Breast, prostate and hematolymphoid malignancies are common causes of CM with death from breast occurring earliest. Majority of the deceased were educated, working-class urban dwellers. More advocacies on public acceptance of cancer screening and cancer preventive lifestyles as well as governments' improvement on workforce training and treatment infrastructure will improve the current CM profile in Port Harcourt.
ABSTRACT
BACKGROUND: Determination of weight in children is an important aspect of their assessment. It has a wide range of usefulness including assessing their nutritional status and drug dose calculation. Despite its usefulness, weight estimation in children in certain conditions can be challenging particularly in emergency situations or in children who are severely ill or cannot stand on standard scales. The Broselow Tape which is a validated tape that is used to estimate weight based on length was developed using height/weight correlations from Western data. However, considering the variations in anthropometric measurements of children from different geographic locations, there is need to ascertain how accurate it is to estimate weight using the Broselow tape among children in Nigeria. AIM: The study was carried out to determine the accuracy in the use of the Broselow Tape in weight estimation among Nigerian children. METHOD: A total 1456 children aged 1-12 years who satisfied the inclusion criteria were enrolled over a 2½ year period from two tertiary health facilities in Enugu state Nigeria. Weight was taken using standard weighing scale and Broselow tape. Data collected was analysed using SPSS. RESULT: Of the 1456 children studied, majority (84.2%) had normal Body-Mass-Index (BMI) while about 4.6% had a low BMI percentile for age. The mean weight difference between the two methods was not significantly different between the 1 to 6 years old category. Significant differences were observed from 7 up to 12 years. The Broselow Tape overestimated weights in 1 year old by 3.88%, 2 years 1.58%, 3 years by 2.13%, 4 years (1.94%) and 5 year (0.07%). After 5 years, the degree of overestimation rises sharply to 4.25% in 6, 9.25% in 7, 7.29% in 8 and 9.29%. 9.18, 11.61% & 6.75% in 9, 10, 11 and 12 years old respectively. The proportion of estimated weights that was within 10- 20% of the actual weight was higher in the 1-6 years age categories compared to weight estimates in older age categories. CONCLUSION: Weight estimates obtained using the Broselow tape correlated better in children that are 6 years or younger compared to those in the older age categories. There is need for re-validation and/or adjustments of the Broselow tape especially in children over 6 years old.

BACKGROUND: Medical education is considered one of the toughest college degrees to acquire. Exploring the factors that determine good academic performance in medical school will help in the planning of curriculum and assist students to navigate through medical school more effectively. METHODS: This cross-sectional and descriptive study enrolled 145 second year clinical students (500 level) of the Enugu State University of Science and Technology in south-east Nigeria using purposive and convenient sampling method. It assessed factors that predicted good academic performances in surveyed students. RESULTS: Medical students without membership in any campus group, those that receive(s) less than ten thousand naira (≈US$27) every month as upkeep allowance, those admitted through the University Matriculation Examination, and students who visit their families on a weekly basis were more likely to have better academic performances than those in corresponding categories. Of these significant predictors of good academic performance, mode of admission into medical school (Rs=-0.310 P=0.001) and monthly allowance students got for upkeep (Rs=-0.281 P=0.001) had the strongest correlation with good academic performances. CONCLUSION: Our study identified factors that correlate with academic performances among medical students. We propose frequent appraisal of these factors and support system that will help improve performance in these students.
ABSTRACT
INTRODUCTION: The prevalence rates of the common histopathologic subtypes of childhood nephrotic syndrome associated with steroid resistance appear to be changing globally. In Sub Saharan Africa (SSA), the trend is similar over the past few decades. AIM: This systematic review aims to determine the current prevalence rates of the histopathologic subtypes associated with childhood steroid-resistant nephrotic syndrome (SRNS) in SSA. METHODS: A search of the PubMed, Google and African Journals Online databases was conducted from January to December 2018 using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) flow-chart to identify relevant articles which met the aim of the systematic review. A qualitative synthesis and descriptive analysis of the extracted data were then conducted. The mean values for the prevalence rates of the reported histopathologic subtypes were calculated. A meta-analysis was not done due to few numbers of studies reviewed. The review is registered with PROSPERO, number CRD42018111916. RESULTS: In the West African sub-region, the currently reported histopathologic subtypes associated with childhood nephrotic syndrome are focal segmental glomerulosclerosis (FSGS), minimal-change nephropathy (MCN), membrano-proliferative glomerulonephritis (MPGN), membranous nephropathy (MN) and mesangial proliferative glomerulonephritis (MesPGN). The picture is the same in South Africa. More importantly, the predominant histopathologic lesions associated with steroid resistance are FSGS (West Africa) and MCN/FSGS (South Africa), with mean prevalence rates of 57.2% and 36.1% respectively. CONCLUSION: The prevalence of FSGS is currently high in childhood nephrotic syndrome in SSA. This histopathologic subtype remains the commonest lesion associated with SRNS in this part of the globe.
ABSTRACT
BACKGROUND: There are vast differences in prevalence rates of urinary tract infection (UTI) reported among malnourished children globally. We conducted a systematic review and meta-analysis to provide estimates of pooled prevalence of UTI among these children and combined UTI risk in comparison with their well-nourished counterparts. METHODS: We systematically searched electronic databases (MEDLINE, EMBASE, ISI Web of Science and African Journals Online; date of the last search: 22 December 2018) for studies reporting either the prevalence of UTI in malnourished children or parallel healthy controls. Eligible primary studies were observational studies of children in English Language reporting UTI prevalence with background malnutrition or with enough data to compute these estimates, as well as studies which reported at the same time UTI prevalence in healthy controls. We synthesized published prevalence rates or associations (odds ratios [OR]) between malnutrition and UTI and their 95% confidence intervals (CI) using random effects meta-regression and explored potential heterogeneity determinants using meta-regression analysis. This review is registered with PROSPERO, number- CRD42018084765. RESULTS: We included 26 cross-sectional and 8 case-control studies reporting on UTI prevalence in malnourished children, and in malnourished children vs. healthy controls, respectively. The pooled prevalence of UTI in 3294 malnourished children was 17% (95% CI, 13, 21%). Heterogeneity was high (I2 = 87.6%; Tau2 = 0.06) as studies varied in their sample size, degree of malnutrition, and study period. Multivariate meta-regression model, including these factors, explained 34.6% of the between-study variance. Pooled OR of UTI in association with malnutrition in 2051 children (1052 malnourished children vs. 999 controls) was 2.34 (95% CI, 1.15, 3.34), with lower between-study heterogeneity (I2 = 53.6%; Tau2 = 0.47). CONCLUSIONS: UTI is more prevalent in malnourished children than in their well-nourished counterparts. Screening and treatment for UTI should be incorporated in the management protocol of malnourished children to improve disease outcomes.

This narrative review aims to highlight the current paradigm on pain management in sickle cell vaso-occlusive crisis. It specifically examines the pathophysiologic mechanisms of sickle cell pain as well as the pharmacologic and nonpharmacologic methods of pain management. Recurrent painful episodes constitute the major morbidity in sickle cell disease (SCD). While adolescents and young adults experience mostly acute episodic nociceptive pain, it is now recognized that a significant number of adult patients develop chronic neuropathic and centralized pain. In fact, current evidence points to an age-dependent increase in the frequency of SCD patients with chronic pain. Management of disease-related pain should be based on its pathophysiologic mechanisms instead of using recommendations from other non-SCD pain syndromes. Pain management in vaso-occlusive crisis is complex and requires multiple interventions such as pharmacologic, nonpharmacologic, and preventive therapeutic interventions. Pharmacologic treatment involves the use of non-opioid and opioid analgesics, and adjuvants - either singly or in combination - depending on the severity of pain. The basic approach is to treat SCD pain symptomatically with escalating doses of non-opioid and opioid analgesics. Given the moderate-to-severe nature of the pain usually experienced in this form of SCD crisis, opioids form the bedrock of pharmacologic treatment. Multimodal analgesia and structured, individualized analgesic regimen appear more effective in achieving better treatment outcomes. Although the current evidence is still limited on the supportive role of cognitive behavioral therapy in pain management, this nonpharmacologic approach is reportedly effective, but needs further exploration as a possible adjunct in analgesia.
ABSTRACT
BACKGROUND: Due to the health and economic benefits of breast milk, the World Health Organization (WHO) recommends that for infants who cannot receive breast milk from their own mothers, the next preferred option is donated breast milk. This recommendation is however rarely practiced in most developing countries where donor milk is not widely accepted. METHODS: This cross-sectional multi-center study enrolled mothers attending antenatal or pediatric clinics in six tertiary institution in south-east Nigeria using purposive and convenient sampling method. Data collection was done using pretested questionnaires. The study aimed to assess the knowledge, acceptability and willingness to donate breast milk and/or use donated breast milk for their infants It also explored factors that determine this behavior. RESULTS: A total of 1235 mothers participated; 39% (480/1225) have heard about the concept of donor milk, while only 10% (79/759) and 7% (81/1179), respectively, had adequate knowledge of the concept and policy on donor milk. Sixty percent indicated willingness to use donor milk or donate breast milk if need arises. Respondents with lower age (p = 0.049) and with higher occupational status (p = 0.001) were more likely to have adequate knowledge of donor breast milk, while respondents with lower educational attainment (p = 0.002) and those who are non-Christians (p = 0.004) were more likely to request financial inducement for donating their breast milk. Adequate knowledge of the concept of donor milk (p = 0.001), preference of donor milk to infant formula (p = 0.001) and requirement of financial remuneration (p = 0.001) were the only significant predictors of willingness to donate and/or receive donated breast milk. CONCLUSION: The knowledge of the concept of donor breast milk and awareness of policies regulating its practice in Nigeria is low, but the prospect of its acceptability is high among mothers surveyed in south-east Nigeria. Targeted public education by relevant government agencies in collaboration with clinicians, community and religious leaders about the concept of donor breast milk to families may help increase the acceptance and practice of donating breast milk and/or use of donated breast milk among mothers in the region.
ABSTRACT
Besides their fundamental role in transfusion medicine, ABO and other histo-blood group antigens are associated with the pathogenesis of some human diseases such as malignancy and thrombosis. Reports also show a possible relationship with the risk of asthma and other forms of respiratory atopy. This paper aims to critically review the current evidence linking ABO histo-blood group with the risk of respiratory atopy in children and adults. A literature search was conducted with PubMed to gather baseline data about this relationship. The search extended to studies published within the past 45 years. First, the molecular mechanism underpinning the role of ABO antigenic system in human diseases comprises a fascinating relationship with von Willebrand factor and several pro-inflammatory and adhesion molecules. Second, specific blood group types vary with asthma phenotypes; severe asthma is associated with B phenotype, while mild and moderate asthma is associated with O and A phenotypes. Third, O phenotype has been linked to allergic rhinitis but only in males. Furthermore, asthma risk is related to O/Lewis negative/secretor phenotypes, while a significant relationship has also been established with B phenotype but not with A and O phenotypes. However, one study failed to establish a significant relationship with any of the ABO blood group antigens. In conclusion, there is no unanimity on the specific histo-blood groups linked to respiratory atopy risk, although asthma phenotypes are associated with specific blood groups. Despite the prospect that this relationship holds for the use of blood-group typing in evaluating respiratory atopy risk in children, more evidence-based studies are still required for its validation.
ABSTRACT
Background Biofuels and other cooking fuels are used in households in low- and middle-income countries. Aim To investigate the impact of cooking fuels on lung function in children in urban and rural households in South-East Nigeria. Methods The multi-stage sampling method was used to enroll children exposed to cooking fuel in the communities. Lung function values FEV1, FVC and the FEV1/FVC ratio, were measured with ndd EasyOneR spirometer. Airflow limitation was determined with FEV1/FVC Z-score values at -1.64 as the lower limit of normal (LLN5). The Global Lung Function Initiative 2012 software was used to calculate the lung function indices. Results The median age (range) of the 912 children enrolled was 10.6 years (6-18). Altogether, 468 (51.6%) children lived in rural areas. Seven hundred and thirty-seven (80.7%) were directly exposed to cooking fuels (418/737, 56.5% in rural areas). Wood and kerosene were the dominant fuels in rural and urban households. The respective mean Z-scores of the exposed children in rural and urban were zFEV1 -0.62, FVC -0.21, FEV1/FVC -0.83 and zFEV1 -0.57, zFVC -0.14, FEV1/FVC -0.75. Few (5.2%, 38/737) of the children had airflow limitation. Most of them (60.5%, 25/38) lived in the rural community; the lowest FEV1/FVC Z-scores were those of exposed to a combination of fuels. Conclusion Exposure to cooking fuels affects lung function in children with airway limitation in a small proportion, Control measures are advocated to reduce the morbidity related to cooking fuels exposure.

Fatalities from perinatal asphyxia remain high in developing countries, and continually assessing its risk factors will help improve outcomes in these settings. We explored how some identified risk factors predict mortality in asphyxiated newborns, to assist clinicians in prioritizing interventions. This was a 4-year prospective study conducted at the Enugu State University Teaching Hospital, Enugu, Nigeria. All newborns who met the study criteria that were admitted to this facility in this period were enrolled and monitored. Data collected were analysed with SPSS Version 18. A total of 161 newborns with perinatal asphyxia were enrolled into the study with an in-hospital incidence rate of 12.81 per 1000 birth and a case fatality rate of 18%. Overall, the APGAR scores were severe in 10%, moderate in 22%, mild to normal in 68%, whereas the SARNAT stages were III in 24%, II in 52%, and I in 25%. In terms of mortality, 66.7%, 22.2%, and 11.1% mortalities were, respectively, observed with SARNAT scores III, II, and I (P = .003), whereas the findings with APGAR were 31.2% (severe), 25.0% (moderate), 25.0% (mild), and 18.8% (normal) (P = .030). Fatality outcome was more correlated with SARNAT (R = .280; P = .000) than APGAR (R = -.247; P = .0125). The SARNAT score significantly differentiated between the degrees of asphyxia in newborns based on gestational age at delivery (P = .010), place of delivery (P = .032), and mode of delivery (P = .042). Finally, it was noted that newborns that were female (P = .007), or born outside the hospital (P = .010), or with oxygen saturations <60% (P = .001), or with heart rate <120 (P = .000), and those with respiratory rate <30 (P = .003), all have significantly higher likelihood of deaths from asphyxia. Therefore, predictors of neonatal mortality from perinatal asphyxia in our centre include being female and being born outside the hospital, as well as low oxygen saturations, heart rates, and respiratory rates at presentation.
ABSTRACT
BACKGROUND: Given the rising incidence of noncommunicable diseases (NCDs) globally, especially bronchial asthma, there is the need to reduce the associated morbidity and mortality by adopting an objective means of diagnosis and monitoring. AIM: This article aims to review the trends and challenges in the use of spirometry for managing childhood bronchial asthma especially in developing countries. METHODS: We conducted a literature search of published data on the use of spirometry for the diagnosis of childhood bronchial asthma with special emphasis resource-poor countries. RESULTS: Guidelines for the diagnosis and treatment of childhood asthma recommend the use of spirometry, but this is currently underused in both tertiary and primary care settings especially in developing countries. Lack of spirometers and proper training in their use and interpretation of findings as well as a dearth of asthma guidelines remains core to the underuse of spirometry in managing children with asthma. Targeting education of health care staff was, however, observed to improve its utility, and practical implementable strategies are highlighted. CONCLUSIONS: Spirometry is not frequently used for asthma diagnosis in pediatric practice especially in resource-poor countries where the NCD burden is higher. Strategies to overcome the obstacles are implementable and can make a difference in reducing the burden of NCD.
ABSTRACT
BACKGROUND: The pattern of infant feeding during the first 1000-day period-from conception to the second birthday-has a significant influence on the child's growth trajectory. The relationship between exclusive breastfeeding and lower risk of childhood obesity has elicited much scientific interest, given the fact that this form of malnutrition is becoming a global epidemic. AIM: This narrative review aims to examine the evidence in the literature linking exclusive breastfeeding with reduction in obesity in children. LITERATURE SEARCH: Using appropriate search terms, PubMed database was searched for relevant articles that met the review objective. RESULTS: Evidence for the protective effect of exclusive breastfeeding against childhood obesity have been provided by studies which explored 5 physiologic mechanisms and those that established the causality between breastfeeding and lower risk of obesity. The few studies that disputed this relationship highlighted the influence of confounding factors. A new insight on molecular mechanisms, however, points to a direct and indirect effect of human milk oligosaccharides on the prevention of overweight and obesity. CONCLUSIONS: The preponderance of current evidence strongly suggests that exclusivity in breastfeeding can prevent the development of obesity in children.
ABSTRACT
BACKGROUND: Poor nutritional practices especially in pregnancy and early childhood can result in dire consequences in the growth and development of a child. METHODS: This study using purposive sampling enrolled 149 women who had carried at least one pregnancy to term in Enugu south east Nigeria. Logistic regression analysis was used to assess association between avoidance of certain food in pregnancy and selected socio-demographic factors. RESULTS: Approximately 37 % of respondents avoided some foods in pregnancy due to food taboos and no relationship was seen between this avoidance of food and maternal educational attainment, parity (number of obstetrics deliveries) and occupation. Snail and grass-cutter meat were the commonly avoided food in pregnancy while egg were commonly avoided in children under-two years old. Some respondent believed eating snail and grass-cutter meat makes a child sluggish and labour difficult respectively while starting egg early for a child could predispose them to stealing later in life. CONCLUSION: Discussion about food taboos during antenatal care visits and during community education can help reduce the traditional belief about certain food in pregnancy and early childhood.

BACKGROUND: In most parts of the world, neonatal mortality rates have shown a slower decline when compared with under-5 mortality decline. A sick newborn can die within minutes if there is a delay in presentation, thus early diagnosis and treatment are essential for the survival of a critically ill newborn. This study investigated factors responsible for delays in healthcare services for the sick newborn and maternal socio-demographic variables that influence these delays in Enugu, South-East Nigeria. METHODS: This was a community-based descriptive study. A total of 376 respondents were randomly selected from 4 of the 17 local government areas of Enugu State. Mothers and/or caregivers that were nursing or had nursed a child in the previous 2 years were enrolled. Self-reported data on delays encountered during healthcare for sick newborn were collected using pretested structured questionnaire. Chi-square and multivariate logistic regression were used to determine the association between causes of delays in newborn healthcare services, maternal socio-demographics and relationships with newborn mortality. RESULTS: Delays in reaching healthcare facilities accounted for the most common delays encountered by respondents, 78.0%, in this study, followed by delays at household level, 24.2% and delays at health facility level 16.0% (P = 0.000). Mothers with knowledge of ≥3 WHO recognized danger signs compared with those with ≤2 were significantly less likely to delay at household (level 1: 40.7 versus 59.3%) (P = 0.017) and reaching healthcare service (level 2: 19.9 versus 80.1%) (P = 0.028). Delays at health facility level (level 3) occurred more at tertiary health facilities (59.0%), secondary health facilities (39.1%) and primary healthcare facilities (19.7%) compared with private health facilities (13.5%) (P = 0.000). CONCLUSIONS: Delays in seeking healthcare at all levels especially those related to transporting the sick newborn to the hospital are a contributor to newborn mortality in Nigeria. Improving access to healthcare could potentially reduce mortality in the sick newborn.
