Background: Polyuria and polydipsia must never be underestimated.Objective and hypotheses: A 7-year-old girl presented with polyuria, polydipsia and nocturia of 1 year duration, during which she underwent outpatient follow up with her general practitioner and urologist. No weight loss or other endocrine signs.Method: Polyuria was confirmed by water balance (120 ml/kg per 24 h), urinary osmolality (222 mmol/kg), plasma osmolality (2...

Introduction: The extracellular calcium-sensing receptor (CaSR) enables the parathyroid glands and other CaSR-expressing cells involved in calcium homeostasis to sense alterations in calcium serum concentrations. Mutations in the CASR gene may produce gain or loss in its activity. Activating mutations cause a hypocalcaemic syndrome of varying severity, as autosomal-dominant hypocalcaemia or Bartter’s syndrome.Case report: We describe a 6 months infa...

Background: The normal recovery of the hypothalamic–pituitary–gonadal axis after discontinuation of therapy with GNRH analogue for precocious puberty has been proven and documented in the last decades. There has been no report in the literature of patients in which a history of GNRH treatment of precocious puberty is correlated with premature ovarian failure.Objective and hypotheses: The aim of the authors is to evaluate the possibility of a co...

With the ever escalating trajectory of childhood obesity, rates of prediabetes and type 2 diabetes (T2DM) are on the incline. Impaired fasting glucose (IFG) and/or impaired glucose tolerance (IGT) constitute a state of prediabetes with high risk for the development of T2DM. Among U.S. adolescents 12–19 years of age, NHANES 2005–2006, the prevalence of IFG, IGT and prediabetes was 13.1, 3.4 and 16.1%, respectively. Overweight adolescents had a 2.6-fold higher rate tha...

Congenital hypogonadotropic hypogonadism (CHH) is a rare disorder characterized by incomplete or absent puberty caused by the lack or deficient number of hypothalamic GnRH neurons, disturbed secretion or action of GnRH, or both. The association of CHH and a defective sense of smell (anosmia or hyposmia) found in approximately half of the CHH patients is termed Kallmann syndrome (KS). CHH is clinically and genetically heterogeneous, and >25 different causal genes have been ...

Background: Childhood IGCT are rare, malignant tumours of the pituitary stalk and pineal region, highly curable (>90%) by multimodal therapies. Neuroendocrine outcomes are thus important. Deficits increase over time but, without longitudinal studies, it remains unclear whether they are primarily disease or treatment related.Objective and hypotheses: To determine, by longitudinal retrospective analysis in survivors, tumour- and treatment-related facto...

Background: Phthalates are industrial chemicals extensively used as plasticizers in a variety of commercial products. Di-(2-ethylhexyl) phthalate (DEHP) is one of the most frequently used phthalates. DEHP is readily metabolized to mono-(2-ethylhexyl) phthalate (MEHP), which is more toxic than its parent compound. There are some animal and in vitro studies suggesting that phthalates can disrupt hypothalamus-pituitary-thyroid axis.Objective and hy...

Background: Brain tumours constitute the second most common tumours in childhood after leukaemia. Infra-tentorial tumours are more common. Most of the supra-tentorial tumours (STT) are in the supra or para-sellar regions. Malignant tumours are rare. The survival is 50–90% with appropriate management. However, STT and/or treatment may lead to traumatic brain injury (TBI) with endocrinopathic sequel.Methods: This is a retrospective hospital based stud...

Background: Copeptin is a surrogate marker for arginine vasopressin (AVP) release in response to hyperosmolal stimuli such as diabetic ketoacidosis (DKA). We aimed to characterize the temporal course (kinetics) of serum osmolality and copeptin during rehydration and insulin therapy in children with type 1 diabetes (T1D) and DKA, and the relationship between both (dynamics).Methods: An observational multi-center study was...

Background: Studies in animal models revealed that brown and white adipocytes derive from different progenitor cells. Molecular characteristics of these cells have not been investigated in detail in humans.Objective and hypotheses: To identify novel markers of human brown adipocyte progenitor cells.Method: Progenitor cells from human paired deep neck and subcutaneous adipose tissue samples were obtained from n=12 subjects ...
