Introduction: Early identification of classic 21OH-Congenital Adrenal Hyperplasia (21OH-CAH) through newborn screening (NBS) is crucial to prevent adrenal crises, especially in males. Today 21 OH-CAH NBS is performed in 5/21 regions of Italy. This study aims to report the results of 21OH-CAH NBS in Italy from 2006 to 2019.Methods: All patients underwent a dried blood spot (DBS) test for 17OH-progesterone (17OHP) within t...

Background: Congenital Hypothyroidism (CH) is the most common neonatal endocrinologic disorder and one of the most preventable causes of mental retardation and neurological alterations in children. The incidence of CH lies between 1 in 2000-3000 newborns. The replacement therapy with levothyroxine (LT4) should be started immediately since studies show that a rapid normalization of TSH and fT4 optimizes the neurodevelopmental outcome. Infants with Down syndrome...

Background: A close association has been reported between obesity and renal damage in adults, but evidence in childhood is still limited.Methods: We retrospectively studied 396 children and adolescents with obesity. Clinical, biochemical, and instrumental evaluations were performed. Patients were stratified according to the metabolically healthy obesity (MHO) and metabolically unhealthy obesity (MUO) phenotypes. Kidney d...

Purpose: The main purpose of the study is to assess the association between obstructive sleep apnea (OSA) and insulin secretion in children with obesity.Objectives: To achieve our aim we have assessed OSA and measured insulin secretion by the using the oral minimal model (OMM) in a cohort of 77 obese children and adolescents.Methods: We retrospectively enrolled children and adolesc...

Background: Carney complex (CNC) is a rare autosomal dominant multiple endocrine neoplasia and lentiginosis syndrome, characterized by abnormal cutaneous and mucosal pigmentation, myxomas of the heart, skin, breast and other non-endocrine tumors. CNC is principally caused by loss-of-function mutations of PRKAR1A gene located at 17q22-24 coding for the regulatory subunit type I alpha of protein kinase A (PKA) gene. Cushing’s syndrome is a rare disorder in...

Background: The rs72613567:TA variant in the hydroxysteroid 17-beta dehydrogenase 13 (HSD17B13) gene has been associated with decreased risk of liver damage.Aims: To investigate the association between the HSD17B13 rs72613567:TA variant and both hepatic steatosis and biochemical markers of liver damage in obese children and to evaluate its potential effect in NAFLD genetic predisposition.<p...

Introduction: PROKR2 is a 384-amino acid G-protein-coupled receptors (GPCR) that regulates GnRH secretion in the hypothalamus. PROKR2 mutations have been described as cause of a certain percentage of of hypogonadotropic hypogonadism and Kallmann syndrome.In 2017 a heterozygous frameshift gain of function mutation of PROKR2 was identified in a 3.5-year-old girl with central precocious puberty (CPP).The aim of our st...

Background: The aim of our study is to determine the relation of vitamin D levels (25(OH)VD) with body-mass index (BMI), age and month of extraction in pediatric patients.Materials and Methods: We present a retrospective review of medical records of patients under 18 years of age visited by the Children's Endocrinology Service (overweight and obesity) and ambulatory pediatrics (healthy and normal weight children) at ...

Congenital hyperinsulinism (CHI) results from inappropriate insulin secretion most commonly caused by mutations in the ABCC8 and KCNJ11 genes which encode for the pancreatic β-cells-ATP-sensitive-potassium channel (KATP) subunits SUR1 and KIR6.2 respectively. Diagnosis of CHI is based on the presence of detectable plasma insulin during hypoglycemia, suppressed β-hydroxybutyrate and NEFA. Diazoxide is the major treatment for CHI, sirolimus had also b...

Background: Growth Hormone Insensitivity (GHI) is usually caused by mutations in the Growth Hormone receptor (GHR). Patients present with short stature associated with high GH and low IGF-I levels and often have midfacial hypoplasia (typical Laron syndrome facial features). Our centre previously described the first GHR pseudoexon mutation (42700896A>G, c. 618+792A>G). The inclusion of this 108bp pseudoexon is predicted to lead to in-frame insertion of...
