Background: Silver Russell syndrome (SRS) is characterized by low birth weight, severe postnatal short stature and distinctive facies. In ~50% of patients, (epi)genetic alterations can be detected (~40% hypomethylation of H19 on chromosome 11, ~10% maternal uniparental disomy (UPD) 7). As SRS patients are usually born small for gestational age (SGA), they are treated with GH to improve height. However, data on long-term effects of GH treatment in SRS patients are very limited....

Background: Preterm birth is associated with hypertension and increased fat contents in later life. Salt sensitivity (SS) could be a mechanism underlying this relationship. In adults SS has been recognised as a cause of hypertension that is related to low birth weight and obesity.Objective and hypotheses: We studied the prevalence of SS in 7–8-year old children born <32 weeks of gestation and/or with a birth weight <1500 g as well as its rel...

Background: Inappropriate management of illness/stress, accidental or deliberate insulin omission are some of the causes of Diabetes ketoacidosis (DKA) in patients with established diabetes. During illness, patients with type 1 diabetes are advised to monitor for hyperglycaemia and ketosis, maintain fluid intake and if required, to administer supplemental insulin. Previous studies have confirmed that comprehensive diabetes self- management education (DSME) programs on manageme...

Background: Dyshormonogenic hypothyroidism is classically a monogenic disease with recessive inheritance. Thyroid dysgenesis showed a multigenic origin in a mouse model of double-heterozygous deletions of Nkx2.1/Pax8 transcription factor genes, suggesting a possible polygenic nature of certain cases of human hypothyroidism.Objective and Hypotheses: To investigate genetic traits of polygenic involvement in dyshormonogenic hypothyroidism,...

Acanthosis nigricans is a common skin presentation of insulin resistance. We may observe different forms of its sevirity. Pathogenesis of this disorder is correlated with an action of insulin to keratinocyte and dermal fibroblasts via interaction with IGFR1.We'd like to present a medical history of two patients admitted to our clinic because of severe acanthosis nigricans. Boys were at the age of 13 and 14 years. We diagnosed carbohydrate metabolism ...

Background: GH treatment is effective in improving adult height (AH) in short children born Small for Gestational Age. If SGA children are short at the start of puberty, they could benefit from combined GH/GnRH Analogue (GnRHa) treatment.Objective and hypotheses: To determine the timing and progression of pubertal development in short SGA children, comparing GH treatment with combined GH/GnRHa treatment.Method: For the present stud...

Background: There are currently no specific growth charts for use in Nigerian children over the age of 5 years. Health workers rely on charts developed by the Center for Disease Control for children in USA (2000CDC US) or the UK 1990 growth charts for British children. It is unknown whether Nigerian children grow to the same height or at the same tempo as American or British children.Objective and hypotheses: To compare the growth of the Nigerian child t...

Background: Steroidogenic factor 1 (SF-1/NR5A1) plays a crucial role in regulating adrenal development, gonad determination and differentiation, and in the hypothalamic-pituitary control of reproduction and metabolism. In men (46, XY) mutations in SF-1/NR5A1 gene cause a wide phenotypic spectrum that ranges from complete testicular dysgenesis with Müllerian structures and amenorrhea, through individuals with mild clitoromegaly or genital ambiguity, to severe penoscrotal h...

Background: Individuals with androgen insensitivity syndrome (AIS) have an increased risk for developing a germ cell cancer (GCC). The risk is low during childhood; therefore, gonads are commonly preserved until after puberty. Little is known about GCC development in AIS during adulthood. This question is particularly relevant as many adult AIS women decline gonadectomy.Objective and hypotheses: To gain insight in attitudes towards gonadectomy in various...

Background: The incidence of perinatal stress hyperinsulinism (PSHI) requiring diazoxide treatment is estimated to be 1:12,000 (Hoe et al., 2006). Diazoxide is used to treat PSHI, but it has been shown to have adverse effects including pulmonary hypertension. Gray et al, reported that of 1.25 million infants admitted to NICUs for hypoglycemia over a period of 18 years, only 1066 received diazoxide suggesting 1:1172 babies had HI however 92% o...
