Background: Congenital adrenal hyperplasia (CAH) is one of the most common inherited endocrinal disorders. Steroid 11β hydroxylase deficiency (11βOHD) is the 2nd most common form of CAH. It is a rare AR disorder caused by CYP11B1 mutations with an incidence of 100 000–200 000 in overall population.Objective and hypotheses: To detect 11β hydroxylase deficiency in patients presenting with clinical manifestations and hormonal findings su...

Prader-Willi syndrome (PWS) is a complex genetic disorder which affects endocrine and neurological systems, metabolism and behaviour. In the neonatal period PWS is characterised by hypotonia, and resultant failure to thrive, whilst in childhood hyperphagia and obesity typically predominate. Patients can develop hypothalamic dysfunction and a range of endocrinopathies, including growth hormone deficiency, hypogonadism and hypothyroidism. Patients with PWS benefit from early and...

Background: Osteogenesis imperfecta (OI) is a genetic disorder mostly associated with mutation in one of the two genes encoding a chains of collagen type 1 (COL1A1 and COL1A2). Severity of the symptoms varies widely, caused by increase bone fragility and low bone mass. However, there is no direct relation reported in osteogenesis imperfecta and panhypopituitarism.Clinical case: Nineteen months old boy was clinically diagnosed with osteogenesis i...

Short-chain L-3-hydroxyacyl-CoA (SCHAD, HADH) deficiency is characterized by diazoxide-responsive hyperinsulinemic hypoglycemia in the neonatal or infancy periods. These patients have severe protein (especially leucine) sensitivity. HADH mutations are recessively inherited with less than 50 patients reported so far. The mechanism behind unregulated insulin secretion in SCHAD deficiency is not understood but may involve changes in protein-protein interactions with glutamate deh...

Background: Patients with isolated growth hormone deficiency (GHD) will routinely have an MRI scan of the pituitary and brain to assess pituitary size and presence of any intracranial lesions. The result may change the threshold for monitoring for further hormone deficiencies. However the test may also detect unexpected or unrelated abnormalitiesAim: To review the incidence of normal and abnormal MRI scans in children with a diagnosis of isolated GHD.</p...

Background: Diagnosis of adrenal insufficiency in the neonatal period is most accurately diagnosed with a short Synacthen test. Some tertiary endocrinology centres advocate random serial cortisol measurements over a 3-h period; a normal cortisol reading during such a test would negate the need for a Synacthen test.Objective and hypotheses: Our aim is to assess whether serial cortisol level readings accurately identifies neonates with normal adrenal funct...

Background: Congenital hyperinsulinism (CHI) is the commonest cause of persistent hypoglycaemia and is due to the unregulated secretion of insulin from the pancreatic β-cells. The role of glucagon like peptide-1, gastric inhibitory polypeptide (GLP1/GIP), and dipeptidyl peptidase-4 (DPP4), is currently unknown in patients with CHI.Objective and Hypotheses: To understand the expression pattern of DPP4 in focal and diffuse disease CHI.<p class="ab...

Introduction: There is considerable variation in practice when assessing adrenal function in adrenal insufficiency; duration of glucocorticoid defined to confer risk, early morning cortisol assay (EMC), Synacthen test (ST) - both low dose (LDST) (1microgram) or standard dose (SDST) (36microgram/kg [maximum 250micrograms]) and symptomatology. At our tertiary children’s hospital, even between departments, there is variation in those identified as being at ...

Pseudohypoparathyroidism (PHP) is a disorder caused by PTH resistance due to a genetic defect in imprinted GNAS cluster. It is characterized by high phosphorus, low to normal calcium and elevated PTH. It is classified into types 1a, 1b, 1c, pseudopseudohypoparathyroidism and type 2. Type 1a is often associated with Albright Hereditary Osteodystrophy (AHO) which is characterized by short stature, round facies, obesity, brachydactyly, ectopic calcifications and developmental del...
