Background: An adrenal crisis (AC) is a life-threatening complication of congenital adrenal hyperplasia (CAH). Despite modern therapies, children with CAH still present with symptomatic adrenal insufficiency (AI) and AC.Objective and hypotheses: The aim of the study was to determine the spectrum of symptoms and signs of AI in children with diagnosed CAH who were admitted to hospital for an acute illness, as well as to evaluate the use of stress dosing an...

Background: Consultations for infantile hypercalcaemia have increased at Sydney Children’s Hospital since guidelines for vitamin D3 supplementation during pregnancy were introduced in 2006. Recent nationwide shortages of low-calcium formula (LCF) suggest this problem may be widespread.Aim: To determine if infantile hypercalcaemia is occurring more commonly, identify potential aetiologies and clinical significance.Me...

Background: Fanconi Bickel syndrome (FBS) is a rare form of glycogen storage disease (GSD) inherited in an autosomal recessive manner and caused by mutations in the SLC2A2 gene leading to the loss of GLUT2 glucose transporter expression. The disease is considered to be rare in which a little more than 100 cases have been reported in the literature. The SLC2A2 gene encodes for GLUT2, a low affinity facilitative glucose transporter expressed in critical tissues ...

Introduction: Allan–Herndon–Dudley syndrome is a rare X-linked inherited disorder characterized by, axial hypotonia, weakness, and severe intellectual disability1 Allan-Herndon-Dudley syndrome is caused by mutations in the SLC16A2 gene (also known as MCT8) This gene is located on the chromosome Xq13.2, mutations of the SLC16A2 gene lead to impaired making a protein that transports thyroid hormone triiodothyronine (T3) into nerve cells, for this re...

A 7 year old girl presented with breast development, mood changes and rapid growth spurt from 6.5 years. Clinically she was tall for her family and had Tanner stage 2 breast development and pubic hair. Bone age was 3 years advanced and pelvic ultrasound demonstrated globular anteverted uterus with endometrial lining and enlargement of the ovaries with follicles. LHRH test confirmed central precocious puberty with peak LH 44mIU/ml and FSH 19mIU/ml, with baseline estradiol of 92...

A 5-year-old patient was brought by her parents toour pediatric endocrinology Outpatient clinic with history of progressive bilateral breast budding andenlargement since 3 months ago. . Her previous medical history were uneventful; there was no family history of precocious puberty. Parents were married, nonconsanguineous, she has 1 other sibling who is well . At presentation, our patient was a well looking girl, She had a full female phenotype: On initial physical examination ...

Background: Type 1 diabetes mellitus (T1DM) is a chronic immune mediated condition where autoimmunity against pancreatic beta cell is triggered by many environmental factors in genetically susceptible person. Association of poor infant feeding practices as potential risk factor for developing T1DM is still debatable.Objective: The aim of this study is to look for association of infant feeding malpractices with type 1 dia...

Background: Prader–Willi syndrome (PWS) results from loss of paternally imprinted genes from the 15q11–13 region and causes hypotonia with weight faltering in infancy, followed later by obesity which is classically attributed to hyperphagia.Objective and hypotheses: To determine, where possible, the age at onset of unwanted weight gain (as opposed to actual obesity) in children with PWS attending a specialist clinic.Metho...

Glucose transporter 2(GLUT2), a transmembrane carrier protein that facilitates glucose movement across cell membranes, is an essential protein in carbohydrate metabolism. Mutation of SCL2A2 gene, which encodes this transporter, leads to a rare well- defined entity called glycogen storage disease type XI (GSD XI) also known as Fanconi Bickel syndrome. The result of this defect is hepatomegaly, proximal tubular dysfunction, fasting hypoglycemia, glucose intolerance, failure to t...

Background: Wolfram syndrome is a rare autosomal recessive neurodegenerative disorder caused by mutations in the WFS1 gene. The WFS1 gene is active in cells of body, with highly expression in the, brain, lungs, heart, inner ear, and pancreas. Within cells, WFS1 gene encodes wolframin protein that is located in a structure of endoplasmic reticulum. Endoplasmic reticulum has critical role in protein folding and material transportation within the cell o...
