Background: The social consequences of COVID-19 pandemic are universally known. In particular, the pediatric population is dealing with a radical lifestyle change. For some risk categories, such as overweight and obese children, the impact of home confinement has been greater than for others. Not only have the increased sedentary life, the wrong diet and social distancing stopped the chance of losing weight, but also worsened the general life conditions.<p...

Background: due to its recently documented role in intercellular tight junction disassembly, zonulin has emerged as a valuable biological marker to assess the integrity of the intestinal mucosal barrier. Experimental studies have shown an association between intestinal permeability and obesity.Objectives: aim of this study was to investigate the relationship between serum zonulin levels, both at baseline and postprandial...

Objective: to assess the prevalence of endocrinopathies in a pediatric population of Rett syndrome (RTT) patients.Design: retrospective observational double center study.Methods: 51 caucasian patients (47 girls, 4 boy) with genetically confirmed diagnosis of RTT were enrolled (mean age: 9.65&pm;5.9 years, range: 1-18 years). The patients were referred from the Rett Center of two It...

Background: Thyroid nodules in children are less common than in adult but are about two-to three-fold at risk of being malignant compared to adults. Plummer's adenoma is a very rare occurrence in pediatrics; there is no literature evidence of this diagnosis in Prader-Willi Syndrome (PWS).Case Presentation: A 9-year-old boy, followed at our Pediatric Endocrinology Outpatients Clinic for PWS (maternal uniparental diso...

Background: “Carney complex” is an autosomal dominant inheritance extremely rare genetic syndrome, usually determined by PRKAR1A (17q22-24) gene mutations. The clinical picture is characterized by speckled skin pigmentation; cardiac, cutaneous and mammary myxomas; schwannomas; endocrinopathies (acromegaly, Cushing syndrome due to primary pigmented nodular adrenocortical disease) and tumors of the endocrine glands.Case...

Background: Distal chromosome 16 duplication syndrome, also known as 16q partial trisomy, is a very rare genetic disorder. Smaller chromosomal copy number variants (CNVs) within the 16q region create partial trisomies, which occur less frequently than full trisomy 16q. Trisomy 16q is generally associated with a multisystemic phenotype including intrauterine growth restriction (IUGR), brain and cardiac defects, intellectual disability and an increased risk of b...

Introduction: Familial male-limited precocious puberty (or testotoxicosis) is a very rare genetic disorder with autosomal dominant transmission that causes gonadotropin-independent precocious puberty due to mutations activating the lutropin-chorionic gonadotropin receptor (LHCGR), which lead to elevated testosterone levels and suppressed gonadotropins. The age of onset is between 2-5 years essentially with penis and testes enlargement, linear growth accelerati...

Background: Osteogenesis imperfecta / Ehlers–Danlos (OI/EDS) overlap syndrome is a rare and recently described disorder of connective tissue, characterized by mutation of COL1A1 (17q21.33) or COL1A2 (7q21.3) genes, involved in alpha-1 and alpha-2 chains of type 1 collagen synthesis. Patients with OI/EDS overlap syndrome could show a phenotype characterized by features of both osteogenesis imperfecta (bone fragility, long bone fractures, blue sclerae, sho...

Objectives: To describe the auditory phenotype and dynamics of hearing thresholds in patients with Turner Syndrome (TS).Patients and Methods: Cross-section study evaluating the hearing thresholds in 246 TS patients (age range 4-44 yrs). Patients were divided into three age groups: Group 1 (79 TS, age range 4.0-12.9 yrs); Group 2 (109 TS, age range 13.0-25.9 yrs,) and Group 3 (66 TS, age range 26.0-44.9 yrs,). Pure tone a...

Objectives: To investigate prognostic markers (age, initial hearing level, karyotype, chronic hormonal therapies, and presence/absence of a mid-frequency dip influence) for hearing loss (HL) in Turner syndrome (TS).Design: Longitudinal cross-sectional and retrospective study.Study Population: 61 TS females (age range 4 - 45 yrs), diagnosed by cytogenetic analysis (49,2% monosom...
