Context: In children with Prader-Willi syndrome (PWS), the benefits of growth hormone (GH) treatment are well established. Currently, when young adults with PWS have attained adult height (AH), they have to stop GH treatment. Several one year studies have shown that GH treatment is also beneficial for adults with PWS, improving body composition. However, little is known about the longer-term effects.Objective: To investi...

Normal IGF-Bioactivity and Low Free IGF-I in Patients with Prader-Willi Syndrome with High Total Serum IGF-I: Immunoreactive IGF-I Concentration Poorly Reflects IGF Bio-Activity and Bio-Availability.

Introduction: Recombinant Growth Hormone (GH) has changed the lives of many patients with Prader-Willi Syndrome (PWS). GH treatment has beneficial effects on body composition, physical performance, cognition, psychomotor development, respiratory function and quality of life of patients with PWS. Due to the narrow therapeutic range, GH treatment is subject to strict limits. Clinicians measure serum immunoreactive Insulin-like Growth Factor 1 ('total IGF-I&#...

Thyroid nodules are rare in pediatric age with an incidence of 1.8–3%. However, the risk of thyroid cancer is much higher in the pediatric population compared with adults. Among the pediatric cancer survivors there is an increased risk of developing a secondary malignancy and the thyroid cancers account for about 10% of these secondary tumors. From 2004 to 2017, we have recruited 43 patients (22 females; 21 males) with thyroid nodules among a population who had presented ...

Germline and Somatic DICER1 Mutations in Familial Papillary Thyroid Carcinoma and Multinodular Goiter

Lumbreras Cesar , Chueca Maria Jesus , Arribas Laura , de Randamie Rajdee , Alonso Angel , Fernandez Pilar , Berrade Sara , Anda Emma , Regojo Rita Maria , Mendiola Marta , Moreno Jose Carlos

Background: The inheritable component of familial Papillary Thyroid Cancer (fPTC) was recently attributed to monogenic defects in a reduced number of genes including DICER1. DICER1 codes for a ribonuclease of the RNaseIII family essential for the biogenesis of microRNAs.Objective and hypotheses: We aimed to identify germline and/or somatic mutations in DICER1 in a familial pedigree with PTC, multinodular goiter (MNG) and other ...

Background: Klinefelter syndrome (KS) has long-term consequences on bone health. However, studies regarding bone status and metabolism in childhood and adolescence are very rare.Objective and hypotheses: The purpose of our study was to evaluate bone status and metabolism in a cohort of KS children and adolescents.Method: This cross-sectional study involves 40 (mean age 13.7±3.8 years) KS children and adolescents and 80 age-mat...

Background: In a recent report we have identified multinodular goiter (MNG) as a condition with an increased risk for thyroid malignancy in children and adolescents.Objective and hypotheses: To report the prevalence and characterization of a prospectively and uniformly followed cohort of pediatric patients with MNG and to retrospectively analyze differences between benign and malignant MNG before surgery in order to identify malignancy predictors.<p ...

The Evolution of Thyroid Function after Hashimoto’s Thyroiditis Presentation is Different in Initially Euthyroid Girls with or without Turner Syndrome

Wasniewska Malgorzata , Salerno Mariacarolina , Corrias Andrea , Mazzanti Laura , Matarazzo Patrizia , Corica Domenico , Aversa Tommaso , Messina Maria Francesca , De Luca Filippo , Valenzise Mariella

Background: Hashimoto’s thyroiditis (HT) is the commonest autoimmune disorder in Turner syndrome (TS). Although there are in the pediatric literature many studies on the relationships between TS and HT, only few of them have specifically investigated whether the association with TS might be able to significantly affect the evolution over time of thyroid function in children and adolescents with HT, by conditioning a different thyroid status prognosis.<p class="abstext...

Immunological Studies in Rapid-Onset Obesity with Hypothalamic Dysfunction, Hypoventilation, Autonomic Dysregulation, and Neural Tumor (ROHHADNET) Syndrome

Background: ROHHADNET syndrome affects children with normal development until 2–4 years of age.Objective and hypotheses: Aim of this study was to evaluate a possible role of autoimmunity in this disorder. In spite of a suspicion for genetic etiology, disease-associated genetic variations have not been identified. A paraneoplastic/autoimmune etiology has been suggested mainly because of the association with neural crest tumors....

A Novel Androgen Receptor Gene Mutation in Two Patients with a 46, XY Disorder of Sex Development

Fernandez Maria Sanz , Arnao Maria Dolores Rodriguez , Sanchez Amparo Rodriguez , de Leon Esther Gonzalez Ruiz , Cancio Monica Fernandez , Parera Laura Audi

Background: Androgen insensitivity syndrome in its complete form (CAIS) is a disorder of hormone resistance characterised by a female phenotype in an individual with an XY karyotype and testes producing age-appropriated normal concentrations of androgens. Pathogenesis is the result of mutations in the x-linked androgen receptor (AR) gene, which encodes for the ligand-activated AR. We report the clinical, biochemical and molecular features of two affected sisters in whom a nove...

Introduction: A transgender individual’s voice may contribute to the negative psychosocial outcomes. Some studies have shown that an incongruence between one’s voice and internal gender identity can be a potential source of ongoing psychological distress and could impact on their social interactions, employment outcomes, and invite verbal or physical harassment. This study was aimed to examine whether early puberal blockage (PB) impacts on self per...
