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...

Background: CDC (Centers for Disease Control and Prevention) reported an increased risk of newly diagnosed diabetes over 30 days after SARS-CoV-2 infection among persons aged < 18 years. Similarly, the results from the DPV Registry demonstrated a significant increase in the incidence of pediatric Type 1 Diabetes during COVID-19 pandemic. The underlying mechanisms are not yet elucidated.Aim: To investigate the incidenc...

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 ...

Background: Type 1 diabetes (T1D) is a chronic disease characterized by autoimmune destruction of pancreatic beta-cells. Dysregulated miRNA levels have been described in T1D patients, though results are inconclusive.Objective and Hypotheses: The aim of this study was to assess the circulating profile of different miRNAs in children at diagnosis of T1D.Method: 27 children with T1D o...

Background: Denosumab is a new class of antiresorptive medication and a fully human monoclonal antibody of the IgG2 immunoglobulin isotype to RANKL. In fact, it binds with high affinity and specificity to RANKL, mimicking the inhibitory effects of Osteoprotegerin, resulting in rapid suppression of bone resorption. Denosumab is commonly used also in pediatric age for treatment of osteoporosis, malignancies, and other benign bone lesions, such as fibrous dysplas...

Background: Insulin resistance (IR) plays a key role in the pathogenesis of type 2 diabetes (T2D). In neurologically impaired (NI) children unfavorable cardio-metabolic risk profile with high prevalence of IR has been reported. We evaluated the prevalence of T2D in NI children and adolescents, in order to define if a dedicated glucose monitoring may be recommended in these subjects.Patients and Methods: We retrospectivel...

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: Young children affected by Type 1 Diabetes (T1D) are prone to glucose fluctuations and hardly reach a stable glycometabolic control, especially when treated with a Multiple Daily Insulin Injections (MDI) scheme. The recent Real-Time Continuous Glucose Monitoring (RT-CGM) System, Dexcom G5, the only available device registered for non-adjunctive insulin intervention, potentially facilitates a better management of the disease. Evidence regarding CGM effectiveness amo...
