Vourdoumpa Aikaterini , Koutaki Diamanto , Vasilakis Ioannis-Anargyros , Bacopoulou Ioanna , Sertedaki Amalia , Charmandari Evangelia , Paltoglou George

Introduction: Mutations in hepatocyte nuclear factor 1Β (HNF1B) gene (chromosome 17q12), lead to monogenic diabetes (HNF1B-MODY or MODY5, OMIM 137920) accompanied by multisystem disorders. HNF1B gene encodes HNF1B protein, a member of the homeodomain-containing superfamily of transcription factors, expressed early in embryogenesis, contributing significantly to organogenesis and the function of many systems (kidneys, liver, panc...

Background: Hashimoto Thyroiditis (HT) and Graves Disease (GD) are conditions known to be caused by abnormal immune response against self-tissues. The biological processes at molecular lever are still poorly understood. A few epigenetic studies have been published so far.Objective: To investigate whether there are differences in DNA methylation within the HLADRB1, CD40L, FOXP3, CTLA4, FCRL3, IL2RA and PTPN22 promoters between young patients with autoimmu...

A Rare Case of ACTH-Independent Cushing’s Syndrome due to Bilateral Micronodular Adrenal Hyperplasia and Myoclonic Dystonia

Vasilakis Ioannis-Anargyros , Kazakou Paraskevi , Kogia Christina , Karaflou Maria , Chrousos George , Charmandari Evangelia

Background: ACTH-independent adrenal Cushing’s syndrome accounts for less than 15% of endogenous Cushing’s syndrome in children. We present a rare case of ACTH-independent adrenal Cushing’s syndrome, which was associated with myoclonic dystonia.Case presentation: A 12-year old girl was referred on account of rapid weight gain, fatigue, growth deceleration and facial hypertrichosis. She had a history of gait instability and ataxia till the ...

Paltoglou George , Avloniti Alexandra , Chatzinikolaou Athanasios , Mantzou Aimilia , Stefanaki Charikleia , Papagianni Maria , Fatouros Ioannis , Mastorakos Ge

Objective: To investigate the association of the gonadal axis with pro- and anti- oxidation, in relation to obesity and pubertal status in boys, before and after a stimulatory exercise bout.Design: Cross-sectional human experimental study.Methods: Ninty-two healthy normal-weight and obese pre- and early- pubertal boys, participated in this study. All subjects underwent a baseline blood sampling followed by an aerobic exercise bout ...

Altered Stress System Activity in Children with ADHD

Angeli Eleni , Johnson Elizabeth , Korpa Terpsichori , Apostolakou Filia , Papassotiriou Ioannis , Chrousos George , Pervanidou Panagiota

Background: Attention-deficit/hyperactivity disorder (ADHD) is the most prevalent neurodevelopmental disorder worldwide. Evidence suggests dysfunction of the fronto-subcortical pathways and the dopaminergic and noradrenergic systems, as well as dysregulation of the stress system, i.e., the hypothalamic–pituitary–adrenal (HPA) axis and the sympathetic nervous system (SNS).Objective and hypotheses: The aim of the study was to examine i) the diurn...

Occasional Detection of an Adrenal Incidentaloma in a Female Adolescent Evaluated for Cardiac Arrhythmias

Kotanidou Eleni , Kyrgios Ioannis , Mouzaki Konstantina , Kleisarchaki Angeliki , Koliatos Panagiotis , Galli-Tsinopoulou Assimina

Background: Adrenal incidentalomas(AIs) are adrenal masses discovered occasionally by radiological evaluation in the absence of clinical features of adrenal disease. Clinical evaluation is important in patients with AIs. AIs are bilateral (10–15%); manifest as nonfunctioning cortical adenomas (70–80%), pheochromocytomas (1.1–11%), subclinical Cushing syndrome (5–20%), primary aldosteronism (1–2%), primary adrenocortical carcinomas (<5%) and metasta...

Achievement of Metabolic Parameter Goals in Children and Adolescent with Type 1 Diabetes According to the Latest ADA/ISPAD Standards of Medical Care in Diabetes in a Pediatric Diabetes Clinic in North Greece

Papagianni Maria , Vamvakis Anastasios , Tsiroukidou Kiriaki , Kosta Konstantina , Mameka Iliana , Chatzakis Christos , Grenda Efthimia , Tsanakas Ioannis

Background: Blood glucose control in children and adolescents with type 1 diabetes (TD1) is the most important goal in order to reduce potential complications. Following up these patients frequently and recording the relative metabolic parameters on a regular basis is necessary.Objective and hypotheses: The aim of the study was to compare the level of metabolic control in the children and adolescents with TD1 that are followed up in our Pediatric Diabete...

L-selenomethionine Supplementation in Children and Adolescents with Autoimmune Thyroiditis: Preliminary Results of a Randomized Double-blinded Placebo-controlled Clinical Trial

Kyrgios Ioannis , Dimopoulou Aikaterini , Kotanidou Eleni , Kleisarchaki Angeliki , Mouzaki Konstantina , Galli-Tsinopoulou Assimina

Background: It has already been documented that selenium treatment has beneficial effects in adult patients with autoimmune thyroiditis, especially in those with a higher titer of antibodies and increased inflammatory disease activity.Objective and hypotheses: To investigate whether daily supplementation of organic selenium at a high dose (200 μg in the form of L-selenomethionine) has any effect on the titer of thyroid autoantibodies.<p class="a...

Seasonality of Month of Birth in Children and Adolescents with Hashimoto Thyroiditis

Kyrgios Ioannis , Giza Styliani , Kotanidou Eleni , Maggana Ioanna , Galli-Tsinopoulou Assimina

Background: A number of studies have previously described seasonality of birth in children with type 1 diabetes, thus suggesting that the autoimmune process may begin during fetal development. However, there is a lack of data regarding autoimmune thyroid disease in childhood.Objective and hypotheses: The aim of this study was to analyse the seasonal birth month pattern in young patients with Hashimoto thyroiditis and compare it with that of youth healthy...

Osteoprotegerin and Insulin Resistance in Childhood Obesity: A New Interplay?

Kotanidou Eleni , Kyrgios Ioannis , Karalazou Paraskevi , Maggana Ioanna , Tzimagiorgis Georgios , Galli-Tsinopoulou Assimina

Background: A positive association between osteoprotegerin (OPG) levels and cardiovascular morbidity and mortality has been recently reported. Additionally, there is evidence that OPG in obese adults participates in the pathogenesis of atherosclerosis and cardiovascular diseases by promoting inflammation, which is known to be linked to insulin resistance (IR). There is few data regarding the relationship among obesity-IR-OPG, in youth.Objective and hypot...
