Background: Congenital Hyperinsulinism (CHI), a condition characterised by dysregulation of insulin secretion from the pancreatic beta cells, remains one of the most common causes of hyperinsulinemic, hypoketotic hypoglycaemia in the newborn period. Mutations in ABCC8 and KCNJ11 constitute the majority of genetic forms of CHI. Biallelic inactivating mutations (homozygous or compound heterozygous) in ABCC8 and KCNJ11 are know...

17-beta-hydroxysteroid dehydrogenase (17-beta-HSD3) deficiency is an autosomal recessive 46XY disorder of sex development (DSD), which results in impaired gonadal androstenedione conversion to testosterone. The phenotype ranges from female to ambiguous genitalia, with wolffian-duct structures and testes. HCG stimulation tests assess testosterone biosynthesis, though biochemical results in confirmed 17-beta-HSD3 deficiency may overlap with gonadal dysgenesis making diagnosis ch...

Context: The early activation of adrenal zona reticularis, denoted by increased circulating levels of adrenal androgens before the age of eight years in girls is called premature adrenarche (PA), while the concomitant appearance of pubic hair is termed premature pubarche (PP). Girls with PA-PP display an unfavorable metabolic, hormonal and psychologic profile, compared to their normal peers and are also at an increased risk of developing polycystic ovary syndrome (PCO...

Background: Osteogenesis imperfecta (OI) due to COL1A1 and COL1A2 mutations is the most common cause of primary osteoporosis.Case presentation: We present a 10-year-old girl with a history of skeletal fragility, starting in the perinatal period. Her parents are not consanguineous and there is no family history of early osteoporosis. To date, she has sustained nineteen low-energy, long bone fractures and she has skeletal deformities (leg length discrepanc...

Introduction: Hypothyroidism without treatment usually leads to delayed puberty in pediatric patients, sometimes it may rarely lead Van Wyk Grumbach syndrome (VWGS) which is characterized by isosexual precocious puberty. Exact mechanism of VWSG is unknown. High thyroid stimulating hormone (TSH) levels may directly effect on follicular stimulating hormone (FSH) receptors and lead precocious puberty. Interestingly simple thyroid hormone replacement therapy resolves symptoms in t...

Background: Main features of the autosomal dominant form of GH deficiency (IGHD II) include markedly reduced secretion of GH combined with low concentrations of IGF-I leading to short stature.Objective and hypotheses: We report on a girl referred for assessment of short stature (−4.6 SDS) at a chronological age of 7 yr 10 mo. The GH deficiency was confirmed by standard GH provocation tests, which revealed severely reduced GH and IGF-I concentration...

Background: The low-dose short Synacthen test is a popular diagnostic test of adrenal insufficiency in children. It is employed by 82% of UK paediatric endocrinologists. Although various dosing strategies exist, 1 μg is most commonly employed, however none of the low-dose forms are commercially available. A BSPED survey revealed 14 different methods for diluting 250 μg/ml ampoules.Objective and hypotheses: Do various dilution strategies result ...

Background: The genetic causes of primary hyperaldosteronism are still being discovered.Results: We present the case of a 17-years-old girl who was found by accident with severe hypertension (TA 180/100 mmHg, bilateral). Her personal history was unremarkable. Her father had hypertension and a paternal aunt had died at 55 due to a stroke. Both her sisters and mother had normal blood pressure. The cardiological examinationshowed concentric left ventricle h...

Aim: To delineate the diagnosis in a case of antibody negative infantile onset diabetes with deranged liver function.Case Report: A female child, first born of consanguineous couple presented with Diabeteic Keto Acidosis and acute liver failure at 9 months of age. She has been treated as a case of Type I diabetes and was discharged on insulin. Child was further evaluated at our center at 11 months of age. On examination, she had a normal anthropometry an...

Background: Measuring testicular volume (TV) by orchidometer is a standard method of pubertal staging in boys. A paucity of evidence exists as to its inter and intra-user reliability and the impact of clinicians’ gender, training and experience on the accuracy of measurements.Objective and hypotheses: We engineered prosthetic models of different size testes to investigate the reliability of TV estimation.Method: The study was ...
