Pediatric Endocrinology Practice in Nigeria: Challenges and Way Forward

The prevalence of endocrine disorders in children in Nigeria is not well known. Therefore the burden of these diseases is often overlooked as most cases are undiagnosed or diagnosed too late; and yet they constitute a significant cause of morbidity and mortality in children. There has been a paucity of Paediatric Endocrinologists, absence of laboratory equipments and even drugs for the treatment of these diseases are often not in stock. The desired attention these endocrine diseases should receive from both health care institutions and the government is lacking. Therefore, the aim of this review article was to highlight the challenges facing the practice of Paediatric endocrinology in Nigeria and to proffer a way forward to building a robust endocrine care services in health institutions in Nigeria.

Pattern of pubertal changes in Calabar, South South Nigeria

Introduction: puberty is an essential physiologic process that is characterized by the appearance of secondary sexual features. Secular changes in puberty occur from one generation to another and need to be documented. The assessment of pubertal stages in a child is only useful if recent and reliable reference data from the same population is available for comparison. The study aimed to profile clinical normative sexual maturity characteristics for children in Calabar, South-South Nigeria. Methods: a cross-section of primary and secondary school pupils aged 6-18 years in the city of Calabar, Nigeria were randomly selected for the study. Sexual maturating rating was assessed using the pubertal staging for breast development and pubic hair as described by Marshall and Tanner (Tanner staging). Testicular volume in boys was measured using the Prader orchidometer. Menarche and "voice break" were established by recall of the event by the girls and boys respectively. Results: a total of 2,830 children were seen, 1542 (54.5%) boys and 1288 (45.5%) girls. The mean age of onset of pubic hair was 11 years in both boys and girls. Pubertal testicular volume of 4 mls was seen in boys at a mean age of 11 years. Breast development in girls occurred at mean age of 11 years and menarche at 13 years. Conclusion: in this study, the onset of puberty is occurring at an earlier age than previously reported in Nigeria with a secular trend of a decreasing age at onset of puberty. These sexual characteristics are rather occurring at similar ages reported from western countries
