The role of routine post-natal abdominal ultrasound for newborns in a resource-poor setting: a longitudinal study.

BACKGROUND: Neonatal abdominal ultrasound is usually performed in Nigeria to investigate neonatal symptoms rather than as a follow up to evaluate fetal abnormalities which were detected on prenatal ultrasound. The role of routine obstetric ultrasonography in the monitoring of pregnancy and identification of fetal malformations has partly contributed to lowering of fetal mortality rates. In Nigeria which has a high maternal and fetal mortality rate, many pregnant women do not have ante-natal care and not infrequently, women also deliver their babies at home and only bring the newborns to the clinics for immunization. Even when performed, most routine obstetric scans are not targeted towards the detection of fetal abnormalities.The aim of the present study is to evaluate the benefit of routinely performing abdominal scans on newborns with a view to detecting possible abnormalities which may have been missed ante-natally. METHODS: This was a longitudinal study of 202 consecutive, apparently normal newborns. Routine clinical examination and abdominal ultrasound scans were performed on the babies by their mother's bedside, before discharge. Neonates with abnormal initial scans had follow-up scans. RESULTS: There were 108 males and 94 females. There were 12 (5.9%) abnormal scans seen in five male and seven female neonates. Eleven of the twelve abnormalities were in the kidneys, six on the left and five on the right. Three of the four major renal anomalies- absent kidney, ectopic/pelvic kidney and two cases of severe hydronephrosis were however on the left side. There was one suprarenal abnormality on the right suspected to be a possible infected adrenal haemorrage. Nine of the abnormal cases reported for follow- up and of these, two cases had persistent severe abnormalities. CONCLUSIONS: This study demonstrated a 5.9% incidence of genito urinary anomalies on routine neonatal abdominal ultrasound in this small population. Routine obstetric USS is very useful but inadequate availability of skilled personnel and cost implications create great challenges in poor resource settings like Nigeria. However, awareness should be created so that parents who can afford such investigations can make informed decisions.

Audit of availability and distribution of paediatric cardiology services and facilities in Nigeria.

BACKGROUND: Paediatric cardiac services in Nigeria have been perceived to be inadequate but no formal documentation of availability and distribution of facilities and services has been done. OBJECTIVE: To evaluate and document the currently available paediatric cardiac services in Nigeria. METHODS: In this questionnaire-based, cross-sectional descriptive study, an audit was undertaken from January 2010 to December 2014, of the personnel and infrastructure, with their distributions according to geopolitical zones of Nigeria. RESULTS: Forty-eight centres participated in the study, with 33 paediatric cardiologists and 31 cardiac surgeons. Echocardiography, electrocardiography and pulse oximetry were available in 45 (93.8%) centres while paediatric intensive care units were in 23 (47.9%). Open-heart surgery was performed in six (12.5%) centres. South-West zone had the majority of centres (20; 41.7%). CONCLUSIONS: Available paediatric cardiac services in Nigeria are grossly inadequate and poorly distributed. Efforts should be intensified to upgrade existing facilities, establish new and functional centres, and train personnel.

The burden of Fallot's tetralogy among Nigerian children.

BACKGROUND: There are only very few reports on Fallot's tetralogy in Africa especially from sub-Saharan Africa. At best tetralogy of Fallot (TOF) is only mentioned as part of reports of surveys of other congenital heart diseases or as case reports in the region. There has been no report on cohorts of children with TOF in West Africa. This article describes the pattern and presentation of children diagnosed with TOF patients in a tertiary hospital in sub-Saharan Africa over a 9-year period. METHODS: Prospective and consecutive review of all subjects with diagnosis of TOF confirmed with echocardiography at the Lagos State University Teaching Hospital (LASUTH) between January 2007 and December 2015. Data were analyzed using Statistical Package for Social Sciences (SPSS) version 20. Descriptive statistics were presented as percentages or means and standard deviation. Means of normally distributed variables were compared using the Students' t-test and proportions using Chi-square test. Skewed distributions were analyzed using appropriate non-parametric tests. Level of significance set at P<0.05. RESULTS: The prevalence of TOF among children presenting at LASUTH at the study period was 4.9 per 1,000 while its prevalence among those with congenital heart disease was 16.9%. There was a male predominance with a mean age of 50.9±45.9 (months) and median age of 36 months. Most children presented within 1-5 years of age. The most common indication for evaluation was cyanosis. One hundred and nineteen out of 165 (72.1%) children were clinically cyanosed on presentation. CONCLUSIONS: TOF is prevalent among Nigerian children. Cyanosis was the commonest presenting feature and indication for evaluation. Most of the subjects presented late hence were diagnosed after 1 year of age. There is a need to increase awareness of TOF in Nigeria to encourage early diagnosis and hence better outcomes in these subjects.

Children With Tetralogy of Fallot in an Urban Centre in Africa.

INTRODUCTION: There is a dearth of literature on tetralogy of fallot (TOF) in children in Sub-Saharan Africa. This study up aims to describe the prevalence, clinical profile and associated cardiac anomaly of children diagnosed with TOF documented over an eight year period in a tertiary hospital in South Western Nigeria. METHODS: A prospective review of all consecutive cases of TOF diagnosed with echocardiography at the Lagos State University Teaching Hospital (LASUTH) between January 2007 and December 2014. Data were analyzed using SPSS version 20. Tables and charts were used to depict those variables. Descriptive statistic are presented as percentages or means and standard deviation. Means of normally distributed variables were compared using the student t test and proportions using chi-square test. Skewed distribution were analyzed using appropriate non-parametric tests. Level of significance set at P < 0.05. RESULT: The prevalence of TOF among children presenting at LASUTH at the study period was 4.9 per 10 000 while its prevalence among those with congenital heart disease was 16.9%. There was a male predominance and most children presented within 1-5 years of age. Chromosomal abnormalities such as Down syndrome, Turners syndrome and CATCH 22 syndrome were documented in some subjects. Some of the subjects had atypical presentation. CONCLUSION: TOF is as common in Nigeria as other parts of the world, there is a need to established cardiac centers to salvage these children. Collaboration from developed countries will be helpful in this resource limited region.

The history of the Pan-African Society of Cardiology (PASCAR): the first 30 years, 1981-2011.

The year 2011 marks the 30th anniversary of the founding of the Pan-African Society of Cardiology (PASCAR). Throughout its brief history, PASCAR has been integral to improving the cardiovascular health of the people of Africa. During the past three decades, many African countries have been vulnerable to political and social turmoil, and PASCAR itself has been repeatedly challenged to press on with its mission, in spite of innumerable practical obstacles. This article celebrates the hard work and dedication of PASCAR's founders and subsequent leaders, and challenges the present and future generations to carry on the charge of furthering the health of Africans.

Health status of working and non-working school children in Ibadan, Nigeria.

Child labour continues to pose a challenge to national and international agencies. This study compares the health status of working and non-working school children in Ibadan, Nigeria. Altogether, 223 working and 230 non-working children were interviewed. Their ages ranged between 8 and 15 years. Fifty-nine (13%) reported fever, 36 (8%) visual problems, 28 (6%) skin lesions, 17 (4%) muscular and joint pains and 5 (1%) diarrhoea. Schistosoma ova were observed in 25 (6%) children. There was no difference in the occurrence of diseases between working and non-working children. Twenty-seven per cent of the children were underweight and 30% were stunted. Malnutrition was more prevalent among working children as 74 (33%) were underweight (p =0.001) and 76 (34%) were stunted. Public enlightenment about the effect of child labour might discourage parents from engaging their school-age children in work. Governments should address the socio-economic factors that promote child labour.
