Background: Very early onset diabetes mellitus (neonatal diabetes mellitus (NDM)) seems to be unrelated to autoimmunity in most instances. A number of conditions are associated with NDM, some of which have been elucidated at the molecular level. Among these, the recently elucidated mutations in the KCNJ11 and ABCC8 genes, encoding the Kir6.2 and SUR1 subunit of the pancreatic KATP channel involved in regulation of insulin secretion, account for one...

Introduction: McCune Albright Syndrome consists of at least 2 of the following 3 features: (1) polyostotic fibrous dysplasia (PFD), (2) Café au lait macules and (3) autonomous endocrine hyperfunction (eg, gonadotropin-independent precocious puberty). Other endocrine syndromes include hyperthyroidism, acromegaly, and Cushing syndrome.Case: 2 year old girl presented with severe hip pain, inability to walk and progressive deformity of right lower limb....

The development of obesity begins early in life. From our large observational studies we know that the age between 3-6 years appears critical for development of obesity in children and once established, childhood obesity regularly persists into adulthood leading to premature morbidity and even mortality. In addition to the mere expansion of fat mass with developing childhood obesity, there are alterations in adipose tissue function such as adipocyte hypertrophy, inflammation a...

Introduction: Complications are frequently reported post hypospadias repair and there is a need to understand the factors that influence their occurrence.Aim: The aim of this study was to identify the occurrence of complications in boys with hypospadias that are in the I-DSD Registry.Methods: Data from boys born with hypospadias between 2010-2020 were obtained from the I-DSD regist...

Background: Analysis of steroids by gas chromatography-mass spectrometry (GC-MS) defines a subject’s steroidal fingerprint. Here, we compare the steroidal fingerprints of obese children with or without liver disease to identify the ‘steroid metabolomic signature’ of childhood non-alcoholic fatty liver disease.Methods: Urinary samples of 85 children (43 girls) age 8.5–18.0 with obesity (BMI >97%) were quantified for 31 steroid meta...

Aim of the Study: Cryptorchidism occurs more frequently in CF-children, and malformed epididymis was found more in cryptorchid boys with abrogated mini-puberty. Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) is transporter protein that acts as a chloride channel. Specifically, CFTR is associated with spermatogenesis and fertility.Patients and Methods: Testicular biopsies for histological and RNA analysis from...

Introduction: Propionic Acidaemia (PA), an organic acidaemia, is characterized by episodes of decompensation with severe metabolic acidosis and hyperammonaemia. PA is associated with low bone mineral density and osteoporosis. Hypocalcaemia is known to occur in 35-65% of decompensations, however the underlying pathophysiology remains unclear. PTH resistance has previously only been described in one case of hypocalcaemia in PA and we report the first use of ...

Background: Pseudohypoparathyroidism type 1b (PHP1b) is caused by epigenetic errors on the maternal GNAS allele at differentially methylated regions (DMRs) associated with exons A/B, XL, and NESP that lead to reduced production of Gαs transcripts most notably in the renal proximal tubule and thyroid follicular cells. Most PHP1b cases appear sporadically, few of which can be explained by paternal uniparental disomy involving chromosome 20q, leading to global methy...

Background: Graves’ disease therapy in young children may be challenging due to lack of therapy options. The safety of Radioiodine Ablation (RIA) has not been proven in children under age of 10 years. Propylthioracil (PTU) therapy has been linked to hepatic failure and became contraindicated in pediatrics.The case: A 6-year-old female was diagnosed with Graves ‘disease and treated with Methimazole (MTZ) and Propranolol. A few days after startin...
