Glutamic acid decarboxylase (GAD) is the enzyme that catalyzes the conversion of L-glutamat into GABA, one of the classical neurotransmitters with neuroinhibitory function. GAD is present in GABAergic neurons and in pancreatic beta cells. It is remarkable that Anti-GAD antibody(Anti-GADab) can have different disease manifestations, i.e., Type 1 diabetes mellitus (T1DM), Stiff-Person Syndrome, limbic encephalitis (LE), epilepsy. Cooccurence of T1DM and LE is reported in the lit...

Background: Congenital hypopituitarism (CH), involving deficiencies in one or more anterior pituitary hormones, is rarely observed in combination with severe joint contractures, termed arthrogryposis. Schaaf-Yang syndrome (SHFYNG), which has phenotypic overlap with Prader-Willi syndrome, may be associated with arthrogryposis. L1 syndrome, a group of X-linked disorders including hydrocephalus and spasticity of the lower limbs, may also present with generalized contractures in r...

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...

The weight of birth affects the weight status and fat distribution in the later period of life. It is suggested that both low and high birth weight pose a risk for cardiometabolic diseases. In this study, the effects of birth weight on body fat mass and body fat distribution parameters during childhood and adolescence period were evaluated.Method: In this cross-sectional study, 4581 children ages between 6-17 years at primary and secon...

Introduction: Turner Syndrome (TS) is known to be associated with a high risk of cardiac anomalies and cardiovascular diseases. Detailed cardiac evaluation at diagnosis and serial evaluation for dissection is warranted.Aim: This study aimed to evaluate TS patients for cardiac pathology using MRI.Methods: Clinical findings, karyotypes, echocardiogram results, cardiac MRI findings of 33 patients with TS were evaluated. Measurements o...

Introduction: Prohormone convertase (PC) is a calcium-dependent serine endoprotease. PC 1/3 is responsible for converting hormones and neuropeptitids which has role on energy homeostasis, food intake,glucose metabolism (a-MSH, CART, NPY, AgRP, Orexin, Hypocretin, Ghrelin, insulin, cholecystokinin, GLP-1, GHRH, GnRH, ACTH, TRH) from proforms to active form. PC 1/3 deficiency’s clinical signs are diarrhea that started in the newborn period, obesity, hypoglycemia, multiple ...

Background: Hypospadias in boys may be associated with a lack of androgen exposure during the masculinisation programming window. As testosterone has effects on the vasculature, we assessed whether boys with hypospadias show any evidence of vascular dysfunction.Methods: Excess foreskin tissue was obtained from boys undergoing hypospadias repair (cases) or circumcision (controls) and small arteries dissected from this tissue. Vascular contractility was as...

Background: Obesity in childhood and adolescence represents a major health problem of our century, and accounts for a significant increase in morbidity and mortality in adulthood. In Greece, more than 30–35% of children and adolescents are overweight or obese.Objective and hypotheses: To investigate the effectiveness of a comprehensive and personalized multidisciplinary management plan in reducing the prevalence of overweight and obesity in childhoo...

Background: Homozygous natriuretic peptide receptor-2 (NPR2) mutations cause acromesomelic dysplasia, type Maroteaux, a skeletal dysplasia with extreme disproportionate short stature and recently, heterozygous NPR2 mutations have been identified also in patients with idiopathic short stature (ISS, 2–6%). SHOX mutations are found in ~2–5% of ISS cases and ~70% of Léri-Weill dyschondrosteosis (LWD) cases, characterized by disproportionat...

Background: Activation of the Wnt/β-catenin pathway is frequent in adrenocortical tumors (ACTs). This pathway and DAX1, a negative regulator of SF1 expression, control adrenal stem/progenitor cells, which can be involved in ACTs formation.Objective: To analyse the association between the Wnt/β-catenin pathway and the expression of a stem cell marker (NANOG), STAT3, DAX1 and SF1 in ACTs.Methods: Patients:...
