Hypercalcaemic disorders in children may present with poor feeding, hypotonia, lethargy, dehydration, vomiting, polyuria, failure to thrive, seizures and hypertension. The causes of hypercalcaemia in children, which can be classified as parathyroid hormone (PTH)-dependent or PTH-independent, are similar to those occurring in adults except that primary hyperparathyroidism and malignancy which the most common causes in adults, and account for >90% of adult patients with hype...

Background: Patients with autosomal dominant hypocalcemia type 1 (ADH1), due to germline gain-of-function calcium-sensing receptor (CASR) mutations, have hypocalcemia and seizures, hyperphosphatemia, hypercalciuria and inappropriately low parathyroid hormone (PTH) concentrations. Treatment for ADH1 comprises calcium and vitamin D analogs, however, their use predisposes to nephrocalcinosis and renal impairment. In contrast, recombinant human PTH(1-34) may incre...

Background: A 10 year old girl with a background history of severe autism and developmental delay presented with significant and rapidly progressive asymmetrical breast enlargement accompanying her relatively rapid progress through puberty. There was associated tissue breakdown exacerbating her discomfort and leading to increasing problems with anxiety and behaviour.Objective and hypotheses: To explore the aetiology of the huge breast development and the...

Introduction: Parathyroid Hormone (PTH) is one of the principal regulatory hormones for calcium and phosphate homeostasis. Reduced PTH concentration in hypoparathyroidism is characterised by hypocalcaemia and hyperphosphataemia.Case Presentation: We report a ten-year-old girl who was admitted to the Department of Paediatrics, Endocrinology, Diabetology with Cardiology due to repeated seizures, hypoalcaemia with suspected...

Background: Protein energy malnutrition (PEM) is a catabolic state with altered energy balance and anorexia. Ghrelin is a peptide hormone, produced by neuro-endocrine cells in the stomach, which stimulates appetite, increases food intake and growth hormone release. Although many trials have shown short term efficacy of ghrelin to increase appetite in anorexic and cachectic patients, data on the children with PEM is scarce.Objective and hypotheses: The st...

Background: Ectopic ACTH syndrome (EAS) is exceedingly rare in children and scarcely reported. Pancreatic Neuroendocrine tumours (NET) can rarely lead to secretion of ectopic adrenocorticotropic hormone (ACTH).Case Characteristics: A14-year-old adolescent boy presented with isolated hyperpigmentation and intermittent abdominal pain and underwent evaluation for primary adrenal insufficiency, but turned out to have subclin...

Background: Anorexia nervosa (AN) is associated with a number of endocrine abnormalities including a low serum free thyroxine level. Hypothyroidism in AN is a recognised condition which is associated with a low normal free thyroxine and triiodothyronine levels (FT4, FT3) with an elevated reverse T3 (rT3). Serum TSH levels are normal or slightly reduced, suggesting a hypothalamic origin to the suppressed thyroid function which is norm...

Background: Currently, little information is available on current growth status according to birth weight at gestational age (BWGA) on Korean adolescents. Herein, the current height and weight of Korean adolescents who were born as small for gestational age (SGA) were compared to those of the non-SGA groups.Methods: Data from the population-based nationwide Korean survey 5th Korea National Health and Nutrition Examinatio...

Background: Blood glucose levels are physiologically controlled by insulin and counter-regulatory hormones, mainly glucagon. Type 1 diabetes patients are deficient in insulin and some level also glucagon. Therefore, bi-hormonal closed-loop system seems to be the best way to control glycemia.Objective and hypotheses: There are two main approaches to add glucagon: (a) as safety measures for rescue in case of hypoglycemia (2) as a mean to optimize metabolic...

Background: The first three children reported to have biallelic mutations in RNPC3 presented with growth hormone (GH) deficiency and pituitary hypoplasia (MIM#618860). RNPC3 codes for a minor spliceosome protein required for U11/U12 small nuclear ribonucleoprotein formation and splicing of U12-type introns. The underlying mechanism causing GH deficiency in these patients is not fully understood. Moreover, whether the association of further ho...
