Background: Type 2 diabetes (T2D) is an emerging disease in the pediatric population. The association between T2D and non-alcoholic fatty liver disease (NAFLD) has been described; the mechanisms responsible for the development and progression of NAFLD are incompletely understood. Evidence of high Haemoglobin A1c (HbA1c) levels and the risk of diabetes complications has been demostrated. Recent evidence suggests that metabolic control may have a role in the dev...

Objectives: The increased incidence of childhood obesity and related non-alcoholic fatty liver disease (NAFLD) has determined the need to identify a non-invasive technique to diagnose and monitor NAFLD. Two-dimensional shear wave elastography (2D-SWE) has emerged as a reliable, non-invasive, tool to evaluate liver tissue elasticity in clinical practice. Aims of this study were to longitudinally evaluate 2D-SWE changes in relation to weight loss, metabolic prof...

Introduction: Noonan syndrome (NS) is one of a group of diseases known as rasopathies, which share a common molecular substrate: alterations in the RAS-MAPK signaling pathway. NS is characterized by clinical and genetic heterogeneity. Up to 50% of cases are caused by variants in the PTPN11 gene, although more than 10 genes have been identified as involved in the pathogenesis of this disease with marked clinical overlap.Objectives...

Introduction: Early identification of classic 21OH-Congenital Adrenal Hyperplasia (21OH-CAH) through newborn screening (NBS) is crucial to prevent adrenal crises, especially in males. Today 21 OH-CAH NBS is performed in 5/21 regions of Italy. This study aims to report the results of 21OH-CAH NBS in Italy from 2006 to 2019.Methods: All patients underwent a dried blood spot (DBS) test for 17OH-progesterone (17OHP) within t...

Introduction and Aims: Autosomal dominant hypocalcemia or type V Bartter syndrome is characterized by hypocalcemia, low parathyroid hormone (PTH), and calciuria, which marks its prognosis due to the risk of nephrocalcinosis. It is caused by activating mutations in the calcium-sensing receptor (CASR) gene (3q21.1), which is expressed in the parathyroid and renal tubules, causing salt and potassium loss, due to the inhibition of the ROMK and NKCC2 channels. We s...

Background: In Italy monogenic forms of hyperglycemia account for more than 6% of cases referred to pediatric diabetes clinics. In January 2019 we started a Monogenic Diabetes Clinic (MDC) with the three main aims: a) implementing a standardized pathway towards genetic testing, 2) ease the revision of complex cases, 3) implement standardized therapies for monogenic diabetes mellitus (MDM) subtypes.Methods: Type 1 diabete...

Background: The emotional distress of caregivers (i.e., parents) of children with long-term conditions affects their self-management behaviors, including treatment adherence. These conditions are diverse and prevalent, including diabetes, obesity, and growth hormone disorders (GHD). The caregivers’ emotional well-being is then a core aspect of their own quality of life, and their children’s. Emerging digital therapeutics solutions may improve such ...

MOPD is known to be caused by homozygous loss-of-function mutations in a specific gene, PCNT. Both intra- and interfamilial clinical variability (even for the same variant) have been frequently observed, which makes it difficult to infer a genotype–phenotype correlation. Pericentrin (PCTN) is a structural protein expressed in the centrosome that plays a fundamental role in anchoring protein complexes, regulating mitotic cycle and thus cell proliferation. High levels of m...

Failure to thrive is a term used to describe inadequate growth or the inability to maintain growth, which usually occurs in early childhood. Case report: female patient, 7 months old, referred to the pediatric clinic of Hospital de Clínicas de Porto Alegre due to a possible syndromic condition. He had no diagnosed comorbidity to date and was using only prophylactic ferrous sulfate and vitamin D. No family history of similar illness. Physical examination showed hypertric...

Deficiency of pregnancy-associated plasma protein-A2 (PAPP-A2), a regulator of IGF-1 availability, causes postnatal growth failure in humans and mice, at least in part through dysregulation of bone size and density. The present study aimed to determine the effects of Pappa2 gene deletion and the response to recombinant murine IGF-1 (rmIGF-1) on femur microstructure and composition. Hydroxyapatite-related crystallography and ionic substitutions were analyzed by X-ray p...
