Carney complex 1 (CNC, OMIM# 160980) is an autosomal-dominantly inherited complex tumor predisposition syndrome associated with skin pigment abnormalities and neoplasms of heart, endocrine glands and other organs. CNC is caused by heterozygous constitutional loss-of-function variants in the PRKAR1A-gene. PRKAR1A codes for the cAMP-dependent protein kinase type I-alpha regulatory subunit, an enzyme that represents an integral part of protein kinase A (PKA) tha...

Purpose: Leptin plays a key role in the regulation of body weight and other endocrine systems. Recently, impairment of leptin gene transcription due to genetic variations in a long-noncoding RNA, also referred as lncOb, has been described in mice. In humans, a correspondent polymorphism (rs10487505) has been associated with relatively low plasmatic leptin levels compared to obesity severity and with early obesity onset.Objectives...

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...

Introduction: Peripubertal children with delayed puberty frequently display a poor growth rate prompting endocrine work-up. Whether priming with sex steroids should routinely be performed in these patients to improve specificity of growth hormone stimulation tests (GHST) is unclear. Treatment with sex steroids in constitutional delay of growth and puberty (CDGP) is also debated.Patients and Methods: This multicenter retr...

Background: Craniopharyngiomas are the commonest pituitary tumours of childhood. Though benign histologically, their localisation and invasive tendency can cause significant neuroendocrine morbidity and late mortality.Objective and hypotheses: To prospectively determine risk factors for neuroendocrine morbidity by longitudinal survival analysis.Method: All children with craniopharyngioma newly presenting to our quaternary centre be...

Background: Isolated aldosterone synthase deficiency is a rare autosomal recessive disorder caused by pathogenic variants in CYP11B2. To date, more than forty different pathogenic variants in the CYP11B2 gene causing isolated aldosterone synthase deficiency have been identified. We report on a novel pathogenic CYP11B2 variant.Case report: The second child (male) of consanguineous, healthy parents, presented shortly after...

Background: Primary Ovarian Insufficiency (POI) and infertility are common concerns of female Childhood Cancer Survivors (CCS) and are known to impact their quality of life. Increased availability of fertility preservation techniques mandate a better understanding of risk factors for POI in this population.Objective and hypotheses: To describe the prevalence of and risk factors for POI in a cohort of adult CCS.Method: Cross-section...

21-hydroxylase deficiency (21OHD) is the most common form of congenital adrenal hyperplasia (CAH) and is caused by mutations in the CYP21A2 gene. 21OHD causes a wide array of clinical symptoms that result from gluco- and mineralocorticoid deficiency and adrenal androgen excess. In most cases, supra-physiological glucocorticoid doses are necessary which may cause short stature, obesity, hypertension, cardiovascular and metabolic co-morbidity with reduced quality of lif...

Background: Among children with idiopathic short stature, Italian data reported a prevalence of short stature homeobox-containing gene (SHOX) deficiency disorders (SHOX-D) near to 1/1.000-2.000 (1.1-15%) with a wide phenotypic spectrum. Current guidelines support recombinant human growth hormone (rhGH) therapy in SHOX-D children, but long-term data are still lacking. This national survey aims to evaluate long-term efficacy and safety of rhGH therapy in Italian...

Objective: Remission rates in young people with Graves’ hyperthyroidism are 25% or less after a 2-yr course of thionamide antithyroid drug (ATD). Immunomodulatory agents could potentially improve outcome by facilitating immune tolerance. We wanted to explore whether rituximab, a B lymphocyte depleting agent, would increase remission rates when administered with a short course of ATD.Design: This was an investigator-...
