Background: Aggrecan (ACAN) is a proteoglycan found in the extracellular matrix of articular and growth plate cartilage. Animal studies have shown that mutations in the ACAN gene lead to premature hypertrophic chondrocyte maturation, causing accelerated cartilage ossification. Patients with ACAN deficiency present with dominantly inherited short stature, often with advanced skeletal maturation and premature growth cessation, as well as early-onset joint diseas...

Background: There is a rise in overweight and obesity among children and adolescents with type 1 diabetes (T1D) in parallel with a rise in the metabolic syndrome (MS) among children and adolescents in general.Objective: The aim of the study was to describe the prevalence and characteristics of the MS in children and adolescents with T1D compared to their healthy counterparts.Design and Sett...

Introduction: Congenital adrenal hyperplasia (CAH) is associated with long-term health problems. However, little is known about co-morbidities and their onset in children and young persons (CYP).Objective: To establish the health status of CYP with CAH across the United Kingdom.Methods: A multi-centre prospective study recruited 102 patients with 21-hydroxylase deficiency targeting...

Background/Objective: Micro-and macrovascular changes are the cause for diabetes complications. Retinal vessel analysis is a unique method to examine microvascular changes in brain derived vessels.Subjects/Methods: Sixty-seven pediatric and adolescent type 1 diabetes patients and 58 healthy control persons underwent nonmydriatic retinal photography of both eyes. Arterioles and venules positioned in the region 0.5 to 1 diameter of the optic disc measured ...

Background: Congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency (21-OHD) is worldwide the most common autosomal recessive disorder caused by defects in the CYP21A2 gene.Objective: The main objective of the study was to evaluate CAH in Cyprus over a 10 year period.Methods: All known patients were included in a population retrospective subset analysis of Cypriot patients with confirmed CAH and their clinica...

Introduction: Lack of impulse control and impaired stress regulation may explain the development of obesity and its challenging therapy, already in youth. To improve self-regulation of overweight adolescents and subsequently their weight status, we tested, whether a biofeedback relaxation exercise decreases stress and whether relaxation services implemented in a novel Smartphone App supported intervention have effects on stress and weight outcomes.Method...

Background: FOXE1 gene variants containing alterations in the alanine tract length may confer susceptibility to primary ovarian insufficiency (POI). BMP15 gene variants have also been related to POI.Objective and hypotheses: To evaluate the contribution of FOXE1 and BMP15 variants in the pathogenesis of POI and to investigate the hypothesis of digenic inheritance in this disorder.Method: FOXE1 and BMP...

Introduction: Patients with congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency (21OHD) have specific plasma and urinary steroid patterns, with 11-oxygenatedC19 steroids established as key adrenal-specific androgens. Monitoring glucocorticoid (GC) replacement remains a challenge in the absence of reliable biomarkers.Aim: To reassess the urinary steroid profile of children with CAH in relation to plasma ...

Introduction&Aim: Activation of mechanistic target of rapamycin (mTOR) as a major regulator of adipogenesis and lipid accumulation is controlled by upstream regulators hamartin/tuberous sclerosis complex (TSC) 1 and tuberin/TSC2. Hamartin and tuberin form a protein complex that inhibits signal transduction to mTOR. The impact of TSC1 deficiency is not clearly defined in human adipose tissue. We identified a likely pathogenic TSC1 splicing variant in a lipo...

Background: Medulloblastoma is the most common malignant pediatric brain tumor. Although survival has improved with oncological therapy, late effects such as endocrine consequences are common, especially growth failure and thyroid dysfunction.Methods: Children diagnosed with medulloblastoma in a pediatric hospital between 2004 and 2014 were studied and followed until 2019. Statistical analysis was performed to estimate t...
