Background: Congenital hypothyroidism (CH) is the most common neonatal endocrine disorder, with an incidence of 1:3000 neonates, and one of the most frequent preventable causes of mental retardation worldwide. Most (65%) cases of primary permanent CH are due to thyroid dysgenesis (TD). However, a genetic cause is identified in less than 5% of CH due to DT.Methods: We performed WES (Whole Exome Sequencing) for siblings with childhood-onset TD and we analy...

Background: GLI2 is a zinc-finger transcription factor of the SHH signaling pathway, expressed during ventral forebrain and pituitary development. GLI2 mutations account for microforms of dominant holoprosencephaly. So far, only 15 unambiguous mutations were found in hypopituitarism –essentially combined pituitary hormone deficiency (CPHD)– frequently associated with holoprosencephaly-like malformations and/or polydactyly.Objective and...

Background: Obesity is a worldwide epidemic affecting adults and children. Social changes throughout history have contributed to modifications in nutrition and physical activity levels. These changes in lifestyle affected health, increasing the number of metabolic and cardiovascular diseases. Obese children already have a low grade systemic inflammation as well as markers of increased cardiovascular risk. The endothelial function is an important and early marker of atheroscler...

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...
