The Ovotesticular Disorder of Sexual Development (OT DSD) is a rare condition characterized by histologic demonstration of both ovarian and testicular tissue in the same individual. Descriptions in literature usually have small samples and do not include patient evolution data. The aim of this study is to describe clinical, biochemical and histological findings, as well as long-term outcomes (including onset and progression of puberty) in patients with OT DSD, accompanied betw...

We demonstrate significant penile growth in an infant with 17 beta HSD-deficiency treated with DHT-gel.Background: The child was born with ambiguous genitalia at full term. Investigations revealed 46,XY karyotype, testosterone and DHT levels were 2.5 nmol/L and <0.1 nmol/L respectively. No female internal genitalia were found. hCG stimulation did not result in an increase in testosterone, but a clinically obvious increase in phallus size. Subsequent ...

Background: Vitamin D may have cardio-protective properties due to its biological actions. In children, observational studies linking actual vitamin D level and blood pressure have yielded conflicting results. Whether early life vitamin D exposure may elicit a programming effect on later systolic blood pressure (SBP) and diastolic blood pressure (DBP) needs further investigation.Objective and hypotheses: We investigated whether higher levels of cord 25-h...

Background: Hyperinsulinaemic hypoglycaemia (HH) is one of the common causes of hypoglycaemia in infants and children. It can cause severe brain injury in children if not treated promptly. Diazoxide is first-line treatment for HH. Glucagon infusion is used in the management of children with HH. However it is unclear what dose of glucagon should be used in children.Objective and hypotheses: To evaluate the efficacy, safety and pharmacokinetics of intraven...

Background: Pycnodysostosis is a rare recessive condition with mutation in the cathepsin K gene, causing reduction in bone reabsorption resulting in abnormally dense and fragile bones. Characteristic features include deformity of the skull, maxilla causing craniofacial, dental abnormalities with skeletal changes and short stature. Growth hormone therapy has been attempted in a small group of patients with Pycnodysostosis to promote final adult height, however has not been show...

Background: Polycystic ovary syndrome (PCOS) in adolescence has a challenging diagnosis and therefore has raised intense discussions. Its prevalence in childbearing age women ranges from 5 to 10%. However, the prevalence in obese adolescents has not yet been reported. Besides, the relationship of PCOS with metabolic and cardiovascular disorders in this specific population has not been established.Objective and hypotheses: We aimed to assess the prevalenc...

Background: Hyperinsulinaemic hypoglycaemia (HH) is a common cause of hypoglycaemia in children. Glucagon is an important counter-regulatory hormone and the role of somatostatin is not known in children with HH.Objective and hypotheses: To understand the roles of glucagon and somatostatin in children with HH.Method: Children admitted for management of HH in our hospital were included in the study. Plasma insulin, glucagon and somat...

Background: Several previous publications have documented the usefulness of Nifedipine for treating hyperinsulinaemic hypoglycaemia (HI). These reports include transient and persistent forms of HI, with and without known genetics, used in monotherapy or in combination with other drugs, and demonstrate various outcomes.Objective and hypotheses: To systematically trial Nifedipine in children with known HI mutations and diazoxide unresponsive, assessing gly...

Background: Costello syndrome may be associated with Hyperinsulinaemic Hypoglycaemia (HI), but this is usually a mild medically-responsive form.Objective and hypotheses: To describe the clinical characteristics, biochemical findings and challenging management of a case of Costello syndrome with severe HI.Method: Review of the patient’s medical records.Results: Male, born to non-consanguineous healthy par...

Background: Hypogonadotrophic hypogonadism (HH) is a complex developmental disorder characterized by a reduction in gonadotrophins (LH, FSH) released from the anterior pituitary. LH and FSH stimulate the ovaries or testes to release sex hormones that cause the onset of puberty, therefore delay in onset or complete absence of puberty is seen in the phenotype, often accompanied by short stature and genital abnormalities. When anosmia accompanies HH in the phenotype it is termed ...
