Introduction: The Covid-19 pandemic drastically modified social life and lifestyle in particular among children and adolescents, promoting sedentary behaviors and unhealthy eating habits. In this scenario, the effectiveness of the outpatient approach for pediatric obesity may decrease.Objectives: Aims of this study were to assess the rate and the factors associated with outpatient drop-out by comparing two groups of chil...

Background: systematic data about endocrinopathies in Rett syndrome (RTT) patients are still scarce and not univocal.Objective: to assess the prevalence of endocrinopathies in a pediatric population of RTT patients.Design: retrospective observational single center study.Methods: 29 caucasian patients (28 girls,1 boy) with genetically confirme...

Background: in general population Hurthle cell cancer (HCC) accounts for 3-7% of all differentiated thyroid cancers (TC) with a more aggressive course, while its relative prevalence and behavior in childhood is uncertain due to the lack of specific literature reviews.Objective: to describe the largest pediatric HCC cohort to date reported and to estimate its relative prevalence among TC variants in childhood.<p c...

Background: About 85–90% of children born small for gestational age (SGA) experience a catch-up growth that occurs mostly during the first year of life and results in a full stature recovery by the age of 2. The remaining 10–15% do not undergo compensatory growth, achieving - if untreated - an adult height approximately 20 cm below their peers.Objective: The aim of this prospective one-center study was to investigate the relation between bone m...

Background: It is reported that children with congenital hypothyroidism (CH) are at increased risk of developing childhood obesity. Moreover, it is known that the timing of adiposity rebound (AR) in childhood is strongly linked with future obesity. Aims of our study were to explore the timing of AR and to identify factors affecting AR in a cohort of children with CH diagnosed by newborn screening and treated with levothyroxine. Design: one-center, retrospectiv...

Background: minipuberty (MP) consists in a postnatal activation of hypothalamic-pituitary-gonadal (HPG) axis, which occurs physiologically in both sexes during the first months of life. FSH and LH peak between 1 and 3 months, stimulating sex hormones secretion. In preterm infants, MP might lead to a stronger and more protracted hormonal stimulation, even if specific literature data are limited and not univocal. Immaturity of the hypothalamic feedback has been ...

Background: Heterozygous loss-of-function variants of fibroblast growth factor receptor 1 (FGFR1) are genetic causes of Combined Pituitary Hormone Deficiency (CPHD), Kallmann syndrome (KS) with anosmia/iposmia, Congenital Hypogonadotropic Hypogonadism (CHH) with normosmia and Septo-Optic Dysplasia. It is well-known that these variants are the main genetic factor underlying the development of CHH and KS; however, they have only occasionally been identified in C...

Background: Say-Barber-Biesecker-Young-Simpson syndrome (SBBYSS) is a rare genetic condition caused by de novo mutations in the KAT6B gene, which encodes lysine acetyltransferase 6B, an enzyme involved in chromatin modification. The clinical phenotype is characterized by global developmental delay and multiple congenital abnormalities, including a number of distinctive facial features (ptosis, blepharophimosis, and mask-like appearance), skeletal involvement (...

Background: Asprosin is an adipokine involved in glucose homeostasis and its plasma levels physiologically increases in fasting conditions and decreases with refeeding. In non-diabetic children and adolescents with obesity, insulin resistance (IR) and impaired fasting glucose (IFG) seem to influence the physiological variation in meal-related asprosin levels 120 minutes after an oral glucose load (Corica et al. doi:10.3389/fendo.2021.805700). No data ...

Background: The typical biochemical phenotype related to obesity, that is high serum thyrotropin (TSH) within normal range, low/normal free thyroxine (FT4) and increased free triiodothyronine (FT3) levels, can be interpreted as a resistance to thyroid hormones. It is unclear the role played by thyroid hormones in the pathogenesis of metabolic derangement associated with obesity.Aim: To investigate the association between...
