Background: Polyuria and polydipsia syndrome (PPS) workup is not straightforward, especially in children. Basal investigations are often not reliable in distinguishing among diabetes insipidus (DI), central (CDI) or nephrogenic (NDI), and primary polydipsia (PP). Water deprivation test (WDT) is often essential, although uncomfortable and not always reliable enough to recognize partial DI. Plasma AVP investigation is not routinely used in the diagnostic pathway...

It is known that a larger number of blood glucose control, glycemic control of patients with type 1 Dm suffers improvement. Likewise, the presence of hypoglycaemias maintained, especially at night and in school-age patients, could have a significant influence on neurological aspects such as night rest, learning and memory. Improved technology has id allowed or development of control devices interstitial glucose, both blinded (retrospective) as erta abi (real time). The free FR...

Introduction: Hepatic steatosis(HS) is a frequent finding in obese children. Insulin resistance, hypertriglyceridemia and abdominal circumference (AC) are known risk factors, similar to Metabolic Syndrome (MS), but the precise pathophysyology remains unexplained.Objectives: To analyze the prevalence of HS as identified by ultrasound as well as acanthosis Nigricans (AN) in two groups of obese patients; with or without presence of MS; by studying anthropom...

Background: Type 1 Diabetes Mellitus (T1DM) often coexists with other autoimmune diseases, either individually or as a part of polyendocrine syndrome (APS I-III). It is frequently associated with autoimmune thyroid, celiac, gastric and Addison’s disease. In the families with T1DM patients frequently coexist different autoimmune diseases (familial autoimmunity).Objective and hypotheses: Evaluating the frequency of associated and familial autoimmunity...

Background: Obesity in childhood and adolescence represents one of the main health problems of the 21st century. Fibroblast Growth Factor 23 (FGF-23) and its co-receptor, Klotho, play an important role in mineral metabolism, however, little is known about their role in obesity.Objective and Hypothesis: To determine the concentrations of FGF-23 and Klotho in children and adolescents with overweight and obesity.<p class="abs...

Background: Adrenocortical Tumors (ACT) is a rare endocrine malignancy with heterogeneous presentation.Aim: To evaluate the clinical, biochemical and pathologic characteristics of pediatric ACT in a single tertiary center.Subjects and methods: Review of 28 medical records with childhood ACT (chronological age (CA) <18 years (y) treated between 1987 and 2017. Clinical, biochemical, and histological features (Wieneke index), stag...

Objective: The complex clinical phenotypes arising from HNF4A and HNF1A mutations are similar and include diazoxide-responsive CHI from infancy and maturity-onset diabetes of the young (MODY) from adolescence. We aimed to characterise the clinical and genetic aspects of a cohort of paediatric patients with HNF4A or HNF1A mutations.Methods: Patients from five international centres over ...

Background: Low bone mineral density (BMD) has been found in up to 50% of adolescents and adults with Prader-Willi syndrome (PWS). High fracture risk has been described in adult PWS patients. However, the mechanism/s of low BMD in PWS have not been clarified. These patients also display high BMI-SDS that prompted us to evaluate the levels of LIGHTTNFSF14, a cytokine involved in pathological bone remodeling and obesity.Objecti...

Background: Based on growth screening rules, severe short stature (i.e. height SDS less than -3), at the age of more than 3 years, warrants diagnostic evaluation in specialized health care. In the absence of apparent underlying cause, targeted and eventually untargeted genetic studies have been proposed. However, the etiology of short stature at the severe end of the spectrum is poorly characterized.Methods: We ...

Background: Single nucleotide polymorphisms (SNPs) related to genes encoding the FSHβ subunit and FSH receptor (FSHB/FSHR) affect FSH production (FSHB c.-211G>T) and receptor sensitivity/expression in vitro (FSHR c.2039A>G & FSHR c.-29G>A). FSHR c.2039A>G, but not FSHR c.-29G>A, is associated with increased FSH levels in adult women, while there are conflicting results on F...
