Although genetic, environmental, and lifestyle factors largely contribute to type 2 diabetes mellitus (T2DM) risk, the role of epigenetics in its pathogenesis is now well established. The epigenetic mechanisms in T2DM mainly consist of DNA methylation, histone modifications and regulation by noncoding RNAs (ncRNAs). For instance, DNA methylation at CpG islands in the promoter regions of specific genes encoding insulin signaling and glucose metabolism suppresses these genes.

Introduction: Frequent relapses and steroid dependence are common treatment challenges of steroid-sensitive nephrotic syndrome (SSNS) in children. Acute respiratory infection (ARI) is the most frequently reported trigger of relapse. Given the role of zinc supplementation in preventing ARI, some studies show that this targeted intervention may reduce relapses in childhood SSNS.

Objectives: There is need to generate epidemiological data regarding paediatric endocrine disorders (PEDs) in sub-Saharan Africa, since little attention has been given endocrine disorders in children in this sub-region over the years. The aim of the study was to determine the sociodemographic characteristics of children with endocrine disorders in our paediatric endocrinology clinic, as well as the pattern of presentation of these disorders.

Methods: This study included paediatric patients who presented to the endocrine clinic over an 11-year period.

Background: Becker's nevus syndrome is a syndrome characterized by the presence of a Becker's nevus with ipsilateral breast hypoplasia or hypoplastic defects of the muscle, skin, or skeleton. The nevus usually consists of a circumscribed, unilateral, irregularly shaped hyperpigmented macule, commonly occurring around the anterior upper trunk, with/without hypertrichosis and/or acneiform lesions. This rare syndrome has not been reported in our locality to the best of our knowledge.

Objectives: Despite the high prevalence of children with sickle cell anaemia (SCA) in West Africa, there is paucity of data on the height velocity and prevalence of growth failure in SCA patients. With advances in clinical care of SCA patients, could there be a spatial and secular trend in the growth pattern of these children? Hence, the compelling needs to embark on this study. The objectives of the study were to determine the prevalence of growth failure among patients with SCA and its correlation with age, gender and age at diagnosis.

Introduction: diabetic complications have been identified as the major causes of morbidity and mortality in persons with type 1 diabetes mellitus (T1DM). Lack of appropriate glycaemic control is a significant risk factor for the onset and progression of long term complications of diabetes. Identifying the determinants of good glycaemic control is therefore imperative.

Background: There is growing concern as regards the emergence of metabolic disorders among children living with the Human Immunodeficiency Virus (HIV) worldwide. However, there is paucity of data on the correlates of metabolic indices among HIV-positive children in Africa.

Methods: This study examined 84 HIV-positive children on HAART recruited from the paediatric infectious diseases clinic of the University of Nigeria Teaching Hospital for blood glucose levels using finger-prick testing with an Accu-check glucose meter and test strips.

Background: Clinically evident microvascular complications are rarely seen among children and adolescents with type 1 diabetes mellitus (T1DM), although early signs develop during childhood and accelerate during puberty.

Aim: The aim of this study was to determine the prevalence of early signs of microvascular complications in children and adolescents aged 9-19 years with a short duration of T1DM by screening for retinopathy and nephropathy.

Methods: A cross-sectional study and participants were consecutively enrolled from the Endocrinology Clinic at Federal Teaching Hospital, Abakaliki.
