Background: Multiple endocrine neoplasia type 2B is a rare genetic syndrome caused by germline mutations in the RET proto-oncogene. Approximately 75% of MEN2B cases are sporadic and caused by de novo RET mutations, whereas 25% of cases occurs in families with an autosomal dominant inheritance. The most common RET mutation found in 95% of MEN2B patients is the substitution of the amino-acid threonine for methionine at codon 918. In infants with de novo mutation...

Early identification of monogenic obesity, a rare condition, is quite challenging for pediatricians. Src-homology-2 (SH2) B adapter protein 1 (SH2B1) is an important component in the leptin-melanocortin pathway and it is found to play an important role in leptin and insulin signaling. In humans a rare deletion of a 220-kb region on chromosome 16p11.2 encompassing approximately 9 genes, including the SH2B1 gene, is associated with a highly penetrant form of isolated severe earl...

Background: Terminal or interstitial deletions of Xp (Xp22.2→Xpter) in males have been recognized as a cause of contiguous gene syndromes showing variable association of apparently unrelated clinical manifestations such as Leri-Weill dyschondrosteosis (SHOX), chondrodysplasia punctata (ARSE), mental retardation (NLGN4), ichthyosis (STS), Kallmann syndrome (KAL1), and ocular albinism (GPR143).Case reports: We report ...

Introduction: We report a series of three siblings, two girls and one boy, diagnosed with Central Precocious Puberty (CPP) respectively at the age of 5.66, 6.67 and 8.5 years, carrying a mutation in the gene encoding the makorin RING finger protein 3 (MKRN3), usually responsible for the development of familial CPP.Methods: We diagnosed CPP in all the patients by performing a GnRH test. We also dosed basal levels of LH, F...

Background: There are two liquid formulations of Levothyroxine currently in use in Italy: one containing ethanol (Tirosint®) and the other ethanol-free (Tifactor®). The aim of our study is to compare the two liquid formulations of Levothyroxine in the first six months of treatment in newborns affected by Congenital Hypothyroidism (CH).Methods: We retrospectively enrolled 156 patients treated with the ethanol-cont...

The identification of anamnestic, clinical and instrumental data indicative of pathological FMS plays a pivotal role in the prevention of ACH complications.Objective: identify key cranio-cervical junction(CCJ)neuroradiological features for the surgical choice and for the neuroradiological decompression outcome.Methods: from a total of 191 patients, we selected 24 subjects with ACH (age:<4years)...

Objective: Allostatic load (AL) refers to the physiological response that occurs in chronic stress burden, Excessive weight gain is an important source of physiological stress promoting chronic low-inflammation state detrimental for health. We estimated AL score among a pediatric population, in order to define a correlation between cumulative biological dysregulation and excess weight.Methods: We enrolled 164 children an...

Background: we depicted gender-differences in metabolic syndrome (MS) clustering before and after puberty in pediatrics, to identify early childhood prevention intervention and treatments.Methods: We considered 1079 children and adolescents. According to body mass index (BMI) percentiles the subjects were classified as normal weight BMI<75th, overweight BMI 75-95th and with obesity BMI>95th....

Background: The periodic fever, aphthous stomatitis, pharyngitis, and cervical adenitis (PFAPA) syndrome, is an autoinflammatory disease characterised by regularly recurrent fever episodes, due to seemingly unprovoked inflammation.Objective and hypotheses: The aim of the study was to assess serum 25-hydroxy cholecalciferol (25(OH)D) concentrations in children with PFAPA and to evaluate longitudinally the effect of wintertime supplementation on 25(OH)D st...

Background: GH has a strong positive influence on bone stimulating both bone elongation and increase in size by enhancing the accrual of trabecular and cortical bone up to the attainment of peak bone mass in young adult.Aim of the study: We compared the effect of two different GH dosages on statural growth and bone geometry in two groups of GH-deficient children at final height. Data has been collected retrospectively from 1994 to 2013.<p class="abst...
