Introduction: Pituitary adenoma (PA) in childhood is a rare disease, accounting for 3 % of all intracranial paediatric neoplasm, and between 3 to 6% of all PA. There are only few large studies describing paediatric pituitary adenoma and even fewer studies with long-term outcome.Methods: In this retrospective study, clinical, biochemical and radiological parameters and outcome of paediatric patients (<16 years...

Background: Children and adults with chronic thyroid disorders (TD) need continuous monitoring as periods of inadequate thyroid hormone substitution can impact metabolism, puberty and fertility. Transition from pediatric to adult-oriented care is often characterized by discontinuity in care resulting in poor health outcomes and impaired quality of life. Transition care (TC) for young adults with TD remains largely unknown.Objecti...

Introduction: ROHHAD syndrome (Rapid-onset Obesity with Hypoventilation, hypothalamic and autonomic dysregulation) is a rare and complex disease with potential fatal outcome. To this day there have been 158 cases reported in the literature while whole exome sequencing has not yet revealed any responsible genes. It usually presents at the age of 2-4 years and the diagnosis is based on the following criteria: 1) rapidly progressive obesity that develops at the a...

Background: Transient neonatal diabetes (TNDM) is commonly caused by a methylation loss in the 6q24 region, either in isolation or as multiple-loci demethylation due to ZFP57 gene mutation. TNDM is biphasic; usually resolves after 2–3 months but often recurs between age 4 and late adolescence.Case: The boy was born at 38 weeks of gestation (birth weight 3340 g, healthy consanguineous Turkish parents, unremarkable pregnancy). He presented at...

Introduction: The envelope protein of Human Endogenous Retrovirus type W (HERV-W-Env) has been shown to be associated with type 1 diabetes (T1D) pathogenesis in adults patients. This protein is expressed in pancreas of T1D patients and it seems to correlate with macrophage infiltrations. In vitro and in vivo studies have demonstrated that HERV-W-Env inhibits insulin secretion and promotes hyperglycemia. Furthermore, HERV could be implicated in other auto-immune disorders. The ...

Background-Hypothesis: Sudden initiation of treatment for diabetes insipidus (DI) with DDAVP causes abrupt volume expansion resulting in particularly high secretion of Atrial Natriuteric Peptide (ANP) (1). ANP blocks all stimulators of zona glomerulosa steroidogenesis, resulting in secondary mineralocorticoid deficiency and acute hyponatremia, causing renal salt wasting (RSW) (2). Cases: Two sisters, a 19-year-old girl (A) and a 7-year-old girl (B) with Wolfra...

Background: Knowledge on the role of diabetes antibodies in CF related diabetes mellitus (CFRD) is scarce.Objective and hypotheses: We aim to inquire the relevance of ß-cell autoimmunity in CFRD.Methods: The German/Austrian/Luxembourgian diabetes registry DPV was searched for CFRD patients. 878 individuals were analyzed by multivariable regression models.Results: 8.7% of patients with CFRD in our cohort ...

Background: Chronic stress and increased adiposity have been associated with each other in children. Further studies are needed, however, to evaluate both the directionality of this association and the mediating metabolic mechanisms.Objective and hypotheses: This study investigates the interrelations between BMI, body composition parameters, indices of the stress response, such as hair and salivary cortisol levels, and, metabolic mediators, such as insul...

Background: Mutations in the gene encoding the Chromodomain Helicase DNA-binding protein 7 (CHD7) are found in 60% of patients with CHARGE Syndrome (Coloboma, Heart Defects, Choanal Atresia, Retarded growth and development, Genital hypoplasia, Ear abnormalities and/or hearing problems) and in 6% of patients with Kallmann syndrome.Objectives and hypotheses: To describe a novel CHD7 mutation and its clinical presentation.<p class="abs...

Background: Since the initiation of neonatal screening programs for Congenital Hypothyroidism (CH) in the 1970’s, a gradual decrease of TSH cut-off limits has been observed worldwide. Nevertheless, lack of universal consensus has led to wide variation of cut-off limits and LT4 therapy criteria among screening programs, even within the same country. The Greek neonatal CH screening program is carried out by a single laboratory that uses one of the lowest cut-off limits worl...
