Identification and Analysis of the Genetic Causes of Premature Ovarian Failure (POF) in a Cohort of Adolescent Girls

Rita Stancampiano Marianna , Laura Carla Meroni Silvia , Di Lascio Alessandra , Gianninoto Moira , Russo Gianni

Introduction: In human, the development of the embryonic gonads represents a complex process involving a large number of genes, some still unknown. Specific pathways have a crucial role for the normal ovarian development, the germ cell genomic stability and hormonal maintenance. These pathways’ dysregulation can lead to POF, clinically manifesting as the absence of pubertal onset and/or amenorrhea.Objective: To identify candidate genes responsible f...

Graves’ Disease in a Pediatric Population: Results from the Last 17 Years at a Pediatric Endocrinology Unit

Carvalho Fabia , Paredes Silvia , Miguel Gomes Maria , Martins Sofia , Marques Olinda , Antunes Ana

Introduction: Graves’ disease (GD), the main cause of hyperthyroidism in children, is caused by thyrotropin receptor stimulating autoantibodies (TRABs) that activate thyroid hormone synthesis, secretion and thyroid growth. Therapeutic options are anti-thyroid drugs (ATD), 131-I or thyroidectomy. This study reports the experience of a Tertiary Pediatric Endocrinology Unit.Methods: Review of GD patients diagnosed from January/2001 to October/2017. Res...

Secondary Thyroid Cancer among Childhood Cancer Survivors: A Single Institution Experience

Muraca Monica , Bagnasco Francesca , Caruso Silvia , Morsellino Vera , Haupt Riccardo , Cabria Manlio

Background: Childhood cancer survivors (CCS) are at increased risk of developing secondary malignant neoplasms (SMN). Radiotherapy is one of the main risk factors, and secondary thyroid cancers (STC) are likely to occur among irradiated CCS.Objective and hypotheses: To evaluate frequency, characteristics, and of STC in the cohort of CCS treated and in follow-up at the Istituto Giannina Gaslini.Method: Survivors treated between 1975...

Identification of Predictor Factors of Growth Outcome in Children with Hypophosphatemic Rickets

Marin del Barrio Silvia , Sancho Paula Casano , Naderi Ruben Diaz , Cots Jordi Vila

Background: The goal of treatment in children with hypophosphatemic rickets (HR) attempts to correct growth and leg deformities. However, growth is compromised despite treatment and patients are at risk of developing nephrocalcinosis in the future. Some factors (sex, age and height at diagnosis) have been related to height outcome, but little is known about the impact in growth of different dosage of treatment or alkaline phosphatase (ALP) levels.Objecti...

The Role of 24-h Ambulatory Blood Pressure Monitoring in Children and Adolescents with Type 1 Diabetes: Early Experience of a Single Centre

Predieri Barbara , Bruzzi Patrizia , Bianco Valentina , Spaggiari Valentina , Mazzoni Silvia , Cattelani Chiara , Iughetti Lorenzo

Background: Ambulatory blood pressure monitoring (ABPM) permits the observation of blood pressure (BP) in a nonmedical environment. In adults, ABPM is better related to renal damage and cardiovascular morbidity than office BP readings. In early stages of type 1 diabetes (T1DM), the role of ABPM is still controversial.Objective and hypotheses: To detect blood pressure abnormalities using 24-h ABPM in children and adolescents with T1DM and to determine the...

Diabetic Ketoacidosis Risk Factors in the Initial Presentation of Type 1 Diabetes Mellitus in Children and Adolescents

Silva Silvia , Ferreira Lia , Aires Sofia , Freitas Joana , Oliveira Ma Joao , Cardoso Ma Helena , Borges Teresa

Background: Diabetic ketoacidosis (DKA) is the most serious acute complication of type 1 Diabetes mellitus (T1DM). It is important to know the factors associated with the development of DKA and elaborate preventive strategies to reduce their prevalence.Objective and hypotheses: To identify DKA predictive risk factors in the initial presentation of T1DM in children and adolescents.Method: We conducted a retrospective study, by analy...

46,XY Complete Gonadal Dysgenesis with Late Diagnosis

Mladenov Vilhelm , Andonova Silvia , Savov Alexey , Hachmeriyan Mari , Popova Ralitza , Iotova Violeta

Background: 46,XY Complete Gonadal Dysgenesis (Swyer Syndrome) is a rare cause for DSD with incidence ≈1:80000. It is characterised by defective formation of the gonads as a result of structural anomalies in the sex chromosomes or mutations in specific genes. In 20% of the patients deletion/mutation in SRY can be found. Mutations, deletions or duplications in other genes (NRD5A1, DHH, DAX1, WNT4, DMRT, etc.) are also reported. The phenotype is completely female and the d...

Adiponectin and IL-6 in Simple Childhood Obesity with and without Hepatic Steatosis

Stagi Stefano , Nanni Laura , Scalini Perla , Luisa Vetrano Maria , Mirri Silvia , de Martino Maurizio , Seminara Salvatore

Background: Non-alcoholic fatty liver disease (NAFLD) represents a spectrum of clinicopathological conditions frequently discovered in obese patients and characterized by multifactorial pathogenesis. Hypoadiponectinaemia and higher interleukin (IL)-6 levels has been related to NAFLD, even if some contradictory findings have emphasized our incomplete understanding of the role of the cytokines in NAFLD.Objective and hypotheses: To investigate the relations...

Prevalence and Characteristics of Polycystic Ovary Syndrome in Obese Adolescents

Ybarra Marina , Franco Ruth , Cominato Louise , Sampaio Raissa , Sucena Silvia , Damiani Durval

Background: Polycystic ovary syndrome (PCOS) in adolescence has a challenging diagnosis and therefore has raised intense discussions. Its prevalence in childbearing age women ranges from 5 to 10%. However, the prevalence in obese adolescents has not yet been reported. Besides, the relationship of PCOS with metabolic and cardiovascular disorders in this specific population has not been established.Objective and hypotheses: We aimed to assess the prevalenc...

A Lipid-Based System for the Oral Delivery of Growth Hormone

Fricker Gert , Pantze Silvia , Parmentier Johannes , Helm Frieder , Hartmann Klaus , Gropp Felix

Background: Bioavailability of peptide/protein – drugs is extremely low after oral administration due to their instability in the gastrointestinal tract or poor absorption.Objective and hypotheses: Oral delivery of growth hormone and somatostatin by adding extreme stable lipids.Method: A liposomal system based on a combination of standard lipids and membrane spanning tetraether lipids, which are extremely stable biomolecules. ...
