Background: Adolescent obesity constitutes a phenomenon with epidemic prevalence in a worldwide context. Increased rates of metabolic syndrome represent a consequence of this epidemic, leading to high risk for chronic diseases in adolescence. The study herein, presents the primary outcomes of a school-based intervention trial regarding the control of the metabolic syndrome among adolescents of Northern Greece.Aims and objectives: To investigate the preva...

Background: Eating disorders constitute serious mental disorders, characterized by a wide range of dysfunctional behaviors related to food. The term mainly includes anorexia nervosa, bulimia nervosa and binge eating disorder, and is closely related to onset during puberty. The study herein, presents the preliminary results of a school-based intervention trial regarding body weight disorders among Greek adolescents.Aims and objectives: To explore the prev...

Precocious Puberty in a Girl With Prader Willi Syndrome

Papagianni Maria , Kosta Konstantina , Lialias Ioannis , Chatzakis Christos , Tsiroukidou Kiriaki , Tsanakas Ioannis

Background: Prader Willi Syndrome (PWS) is a rare genetic disorder with a wide range of symptoms manifestation. Main characteristics are hypotonia, growth retardation, feeding difficulties in neonatal period, increased appetite and obesity in childhood, delayed puberty or hypogonadism in adolescence. It is also associated with behavioral disturbances and impaired cognitive function. The genetic defect is located on the 15q11-13 chromosome.Objective and h...

A Novel, Synonymous, Heterozygous, Splicing Variant Affecting the Intracellular Domain of the Growth Hormone Receptor: Causality for Mild Growth Impairment and IGF-I Deficiency in an Affected Patient?

Efthymiadou Alexandra , Papanastasiou Anastasios , Zarkadis Ioannis , Hwa Vivian , Chrysis Dionysios

Introduction: Although the majority of Growth Hormone insensitivity syndrome (GHIS) cases are classical, the spectrum of clinical phenotypes has expanded to include ‘atypical’ GHIS subjects with milder phenotypes due to very rare heterozygous GHR mutations with dominant negative effects.Case description: A 13 year old pubertal boy was presented with short stature (−1.7SD) and delayed bone age (11 6/12). Final adult height was &#8...

Determination of the Minimal Clinically Important Difference in the Six-Minute Walk Test for Patients with Hypophosphatasia

Tomazos Ioannis , Moseley Scott , Sawyer Eileen , Iloeje Uche

Background: Hypophosphatasia (HPP) is a rare, inherited, metabolic disease caused by loss-of-function mutation(s) in the gene encoding tissue nonspecific alkaline phosphatase (TNSALP). Poor skeletal mineralisation, muscle weakness, pain, and accompanying complications characteristic of HPP result in impaired physical function, decreasing ability to perform daily activities, and quality of life. Improvement in physical function is a treatment target, yet established physical ac...

Low Circulating Levels of DKK-1 Protein in Obese Children Indicate Suppression of Canonical Wnt Signaling

Kanaka-Gantenbein Christina , Terpos Evangelos , Chrousos George , Papassotiriou Ioannis

Background: Secretion of Wnt-proteins by adipose cells plays an important role in the control of adipogenesis. The Wnt-antagonist, dickkopf-1 (DKK-1), is secreted by human pre-adipocytes and influences adipocyte maturation and growth. DKK-1 mRNA increases 6 h after onset of human adipogenesis followed by an increase in DKK-1 protein. Of note, DKK-1 protein has been implicated also in bone remodeling pathways.Patients and Methods: In this study we measure...

Coexistence of Elevated Chitinase 3-Like Protein 1 and von Willebrand Levels in Prepubertal Obese Children

Kyrgios Ioannis , Stylianou Charilaos , Kotanidou Eleni , Galli-Tsinopoulou Assimina

Introduction: Obesity as a chronic inflammatory disease is associated with impaired prothrombotic state leading to atherothrombosis. A variety of prothrombotic factors have been implicated in the pathophysiology of this phenomenon, especially the von Willebrand factor (vWF) produced in endothelium, megakaryocytes and subendothelial connective tissue. The aim of this study was to investigate any possible association between the new inflammatory marker chitinase 3-like protein 1...

Important Links Between Fat Derived Proteins and Bone Remodeling Factors in Lean and Obese Girls

Kanaka-Gantenbein Christina , Terpos Evangelos , Chrousos George , Papassotiriou Ioannis

Background and aims: Fat and bone are linked by a multitude of pathways supporting a skeleton appropriate for the mass of adipose tissue of the organism. We aimed to investigate the relations of adipose tissue hormones such as leptin, adiponectin, retinol-binding-protein-4 (RBP-4) and lipocalin-2 along with the low grade inflammation marker hs-CRP with markers of bone metabolism such as osteoprotegerin (OPG), receptor-activator of NF-κB ligand (RANKL), osteocalcin, C-term...
