Background: Hashimoto’s thyroiditis (HT) has been linked to papillary cancer in adults but not in children and adolescents. Moreover, there is no agreement on the more appropriate frequency of thyroid ultrasound (TS) in the follow-up of children with HT.Objective and hypotheses: The aim of the study was to investigate the incidence of thyroid nodules and of thyroid cancer in a large group of children and adolescents (567) with HT followed-up for a m...

Background: The replacement therapy with levo-thyroxine (LT4) in congenital hypothyroidism (CH) aims to ensure normal growth and neuropsychological development. Few data are available about the appropriate dose during childhood and early adolescence.Objective and hypotheses: i) To evaluate LT4/kg per day requirement from diagnosis until 12 years of age; ii) to assess any differences in relation to the different etiology of CH as concern...

Background: Data regarding epidemiology and management of Diabetic Ketoacidosis (DKA) in Italian children with T1D at disease onset are lacking.Method: From 1/1/2012 to 31/12/2013 a survey on DKA was conducted in all paediatric Centres belonging to the Italian Society for Pediatric Diabetology and Endocrinology. DKA was defined according to the ISPAD criteria. The following data were collected: treatment according ISPAD protocol yes or not, type of rehyd...

Background: The hepatokine FGF21 signals through a dual receptor complex consisting of FGFR1c and the obligatory co-receptor β-Klotho to regulate glucose and lipid metabolism. Interestingly, female mice with Fgf21 transgenic overexpression are not only resistant to high-fat diet induced obesity but also present with hypogonadotropic hypogonadism (HH) and infertility. Loss-of-function (LOF) mutations in FGFR1 are a frequent cause of congenital HH (CHH). W...

Background: Type 1 diabetes (T1D) is a risk factor for cardiovascular disease (CVD) and alterations may manifest as early as in adolescence. Increased physical activity and reduced sedentary behavior reduce the risk of CVD development in general adult populations, but knowledge is limited on their associations with early markers of CVD risk in pediatric T1D.Objective: Estimate associations of physical activity and sedent...

Introduction: Improvements in the treatment of acute lymphoblastic leukaemia (ALL) and non-Hodgkin lymphoma (NHL) have increased survival, with the consequent concern about the long-term effects that childhood chemotherapy may have on ovarian function. AMH constitutes an indirect, reliable biomarker of the ovarian reserve, useful for the assessment of cancer therapy-related ovarian damage.Aim: To evaluate small ovarian f...

Introduction: Achondroplasia is caused by a pathogenic mutation in the FGFR3 gene, leading to impaired endochondral bone growth and multiple medical complications. Vosoritide, a modified recombinant human C-type natriuretic peptide (rhCNP), was approved by the European Medicines Agency (EMA) in August 2021 for treating genetically confirmed achondroplasia in patients aged ≥2 years until closure of epiphyses. Acorn is the first treatment-based registry for a...

Background: Infants with Prader-Willi syndrome (PWS) exhibit stunted growth. However, little is known about the role of genes expressed from the imprinted PWS domain in healthy infants. This study aimed to analyze the relative gene expression of the SNURF-SNRPN/UBE3A cluster in the imprinted PWS domain in umbilical cord tissue, and its potential association with prenatal and postnatal growth in apparently healthy infants.Methods:...

Objectives: Hyperphagia and severe obesity may result from impaired melanocortin-4 receptor (MC4R) signaling due to rare biallelic variants in POMC or PCSK1 (proopiomelanocortin [POMC] deficiency) or LEPR (leptin receptor [LEPR] deficiency), Bardet-Biedl syndrome (BBS) or acquired hypothalamic obesity (HO). Previously, setmelanotide in patients aged 2-17 years was well tolerated and improved weight-related measures and hunger severit...

Background: Noonan Syndrome (NS; OMIM 163950) is a common autosomal dominant disorder distinguished by facial dysmorphism, short stature, heart defects, chest deformities, and learning disabilities or mental retardation. NS stems from heterozygous germline causative variants in genes regulating the RAS/MAPK signaling pathway, including PTPN11, SOS1, RAF1, RIT1, KRAS, NRAS, BRAF, LZTR1, and SOS2. The condition exhibits considerable clinical variability and shar...
