Strengthening retinopathy of prematurity screening and treatment services in Nigeria: a case study of activities, challenges and outcomes 2017-2020.

OBJECTIVES: Retinopathy of prematurity (ROP) will become a major cause of blindness in Nigerian children unless screening and treatment services expand. This article aims to describe the collaborative activities undertaken to improve services for ROP between 2017 and 2020 as well as the outcome of these activities in Nigeria. DESIGN: Descriptive case study. SETTING: Neonatal intensive care units in Nigeria. PARTICIPANTS: Staff providing services for ROP, and 723 preterm infants screened for ROP who fulfilled screening criteria (gestational age <34 weeks or birth weight ≤2000 g, or sickness criteria). METHODS AND ANALYSIS: A WhatsApp group was initiated for Nigerian ophthalmologists and neonatologists in 2018. Members participated in a range of capacity-building, national and international collaborative activities between 2017 and 2018. A national protocol for ROP was developed for Nigeria and adopted in 2018; 1 year screening outcome data were collected and analysed. In 2019, an esurvey was used to collect service data from WhatsApp group members for 2017-2018 and to assess challenges in service provision. RESULTS: In 2017 only six of the 84 public neonatal units in Nigeria provided ROP services; this number had increased to 20 by 2018. Of the 723 babies screened in 10 units over a year, 127 (17.6%) developed any ROP; and 29 (22.8%) developed type 1 ROP. Only 13 (44.8%) babies were treated, most by intravitreal bevacizumab. The screening criteria were revised in 2020. Challenges included lack of equipment to regulate oxygen and to document and treat ROP, and lack of data systems. CONCLUSION: ROP screening coverage and quality improved after national and international collaborative efforts. To scale up and improve services, equipment for neonatal care and ROP treatment is urgently needed, as well as systems to monitor data. Ongoing advocacy is also essential.

Analysis of Presentations and Outcomes of Care of Children with Disorders of Sexual Development in a Nigerian Hospital.

STUDY OBJECTIVE: To describe the presentation, diagnosis, management, and short-term outcome of children with disorders of sexual development (DSD) in the context of multidisciplinary team care. DESIGN: Prospective descriptive study. SETTING: University Teaching Hospital. PARTICIPANTS: All children who presented with genital ambiguity. INTERVENTIONS AND MAIN OUTCOME MEASURES: Records of all patients diagnosed and managed for DSD between January 2011 and December 2016 were reviewed. The care pathway included clinical, laboratory, internal genitalia evaluation, and panel (including parents) meeting. RESULTS: Fifteen children presented with DSD at a median age of 20 months. Only 5/15 (33.3%) presented in the neonatal period. Ten of fifteen patients (66.7%) presented with genital ambiguity. Ovotesticular DSD was the most common diagnosis (9/15; 60%). Seven of the patients were genetically female (46, XX), 1 was genetically male (46, XY) and 1 without genetic diagnosis. Six patients were assigned male gender and they underwent male genitoplasty. Five of them had excision of Müllerian structures with gonadectomy. Three of fifteen patients (20%) were diagnosed as 46, XX DSD, at a median age of 7 years. All of them were due to congenital adrenal hyperplasia and underwent female genitoplasty. Two patients were diagnosed as XY, DSD. They were both raised as female at presentation and were reassigned male sex. Both had urethroplasty done. Four patients had postoperative urethrocutaneous fistula and 1 had partial wound dehiscence. The median follow-up period was 21 months (interquartile range, 2-26 months). CONCLUSION: The frequency of ovotesticular DSD is high in our setting. The decision of sex assignment was finally made at a median age of 7.5 months in most of our patients with satisfactory short-term surgical outcome.

Intrauterine growth standards: a cross-sectional study in a population of nigerian newborns.

The aim of the study was to define an intrauterine growth curve for a population of Nigerian newborn babies. A cross-sectional observational study design was adopted. Weight, length and head circumference were all measured in consecutive singleton deliveries at the University of Ilorin Teaching Hospital over a 3-year period. Gestational age (GA) of the babies was estimated from the last menstrual period or first trimester ultrasound. The estimates obtained were clinically validated using the Ballard score. Mean birth weights and percentiles of the weight, length and head circumferences for the respective GA were estimated using the SPSS 15 software package. A total of 5273 babies were recruited for the study with GA ranging from 25-44 weeks. Comparison of the mean birth weights of the various GA with the data from Denver, Colorado, showed that Nigerian babes tended to weigh less at the early GA, although these differences were not statistically significant. Between 26-36 weeks, the average weights of both sexes were similar; however, beyond this time point there was a consistent increase in the average weight of the males over the female babies. Growth curves for Nigerian newborn babies were generated and showed that the mean birth weight of Nigerian preterm babies was lighter than that of babies in Colorado. The impact of these differences on the classification of newborns will require further evaluation.

Type 1 diabetes mellitus in the African population: epidemiology and management challenges.

Type 1 Diabetes Mellitus (T1DM) is a growing concern worldwide; while there has been a great improvement in the knowledge, epidemiology and management of this condition in the developed worlds, there has been little or no improvement in sub-Saharan Africa. The true burden of this disease is not even known, but a difference in the pattern and outcome of T1DM in the sub-Saharan Africa compared to the western World seems to be present. Moreover, much of the available data is not population-based and is of limited value for making generalizations about Diabetes in children of Sub-Saharan Africa. Despite the limitations, there is evidence that these populations may be important for studying the aetiology and natural history of Type 1 diabetes. Effective management and/or prevention of diabetes and its complications in Sub-Saharan African children should adopt multidisciplinary approaches. In order to improve care for diabetes patients in developing countries, specialized clinics need to be established.
