Background: Weight status in children is commonly defined using BMI (SDS), but this measure is problematic due to the skewness of the BMI distribution and its age-dependant increase. In addition, it is difficult for physicians or parents alike to grasp what a certain value means. Excess body weight (EBW) is frequently used in adult patients in the context of bariatric surgery.Objective and hypotheses: An appropriate definition for the paediatric populati...

Introduction: The prevalence of pediatric type 2 diabetes (T2D) increased over the last 2 decades, related to the rise in obesity. Meanwhile, treatment options for T2D have evolved considerably. Therefore, we analyzed changes in treatment approaches for pediatric T2D over two decades.Material and Methods: Patients with T2D from 321 pediatric diabetes centers (Austria 24, Switzerland 2, Luxemburg 1, Germany 290) were reco...

Background: Lifestyle interventions show a long lasting weight reduction in only 10–20% of obese children and adolescents. Leptin as one major player within the central regulation of food intake and energy expenditure is most likely to mediate the endogenous drive for weight regain.Objective and hypotheses: To estimate weight regain after weight loss and the role of leptin in regain.Method: We included 153 obese children/adole...

Background: In addition to its function in circadian rhythm Melatonin plays an important role in energy metabolism and body weight regulation. In animals pinealectomy induces insulin resistance and administration of melatonin to diabetes prone rats ameliorates their glucose metabolism. Furthermore loss-of-function mutations of the melatonin receptor gene are associated with insulin resistance and DM II in humans.Objective and hypotheses: So far the effec...

Introduction: Childhood obesity shows increasing numbers worldwide and presents as a global health issue due to multiple metabolic comorbidities. About 1 % of adolescents with obesity develop type 2 diabetes (T2D), however little is known about the genetic and pathophysiological background in young age. Genome-wide association studies in adults revealed genes with increased diabetes risk, most of them regulating insulin secretion. The objective of this study w...

Background: Inter-individual differences in the metabolism of cortisol have been postulated to emerge during puberty, and might be explained by a complex interplay of genetic and environmental factors. The aim of the current study was to estimate the relative contributions of genetic, shared environmental, and unshared environmental factors on cortisol metabolism in a longitudinal twin cohort assessed at pre-pubertal, mid-pubertal and post-pubertal ages....

Context: Congenital hypothyroidism from thyroid dysgenesis (CHTD) is mainly a sporadic and non-syndromic condition occurring in 1:4,000 live births. In contrast to rare cases of syndromic monogenic CHTD, non-syndromic (NS) CHTD shows low familial recurrence risk (~2%) and low concordance rate between MZ twins, suggesting a two-hit scenario combining post-zygotic events with either a de novo monogenic mutation or incomplete penetrance of polyg...

Background: Minipuberty denotes a period 1–6 months postnatally in boys during which a transient activation of the hypothalamic-pituitary-gonadal axis is observed. This early hormone activation can be used diagnostically in patients suspected of pituitary deficiency and differences in sex development. However, its significance for prediction of reproductive function in healthy young men is unknown.Objective: To eval...

Purpose: We aimed to determine the frequency and distribution of intracranial pathologies in patients over 8 years of age by evaluating MRI images of patients diagnosed with early puberty-rapidly progressive.Materials and Methods: The study comprised 118 female patients diagnosed with precocious puberty (PP) and rapidly progressive early puberty (RPEP). The onset of puberty in girls before the age of 8 years is defined a...

Introduction: Longitudinal skeletal growth is achieved by enchondral ossification in epiphyseal growth plates (GP) of long bones and vertebrae. These highly organized cartilaginous tissues contain chondrocytes of all differentiational stages classified in three distinct zones named resting, proliferative and hypertrophic. Separated analysis of individual zones is essential in basic GP research thus efficiency of different zonal separation methods confers high ...
