Background: The association of NF1 with optic pathway glioma (OPT) and GH hypersecretion was initially described in some isolated cases, while the presence of PP was more frequently reported in these patients. Association of gigantism and precocious puberty (PP) in five children with OPT (isolated in two and associated with NF1 in three cases) has been recently published.Aims: To evaluate the frequency of GH hypersecretion in children with NF1 and OPT, t...

Background: Patients with childhood-onset GH deficiency (GHD) are usually retested in late adolescence or young adulthood, after achievement of final height, to verify whether they need to continue GH treatment. Most of the patients found to have idiopathic GHD when tested as children have normal GH responses when retested in the early or late adolescence. Indeed, the 2007 Consensus guidelines for the diagnosis and treatment of GHD adults recommended that idiopathic GHD patien...

Background: Elastargene 3C (E3C) is a cream specifically designed to improve lipoatrophy in patients with diabetes. It is made by many ingredients, among whom are elastin, arnica, collagen, caffeine, and L-carnitine.Objective and hypotheses: We started a 6-month, double-blind, randomized trial to test the efficacy of E3C in children with type 1 diabetes (T1D) using insulin pump (CSII), in whom infusion set usually left little withe scars.<...

Introduction: Childhood obesity is associated with several complications, involving many systems. The prevalence of respiratory problems, such as obstructive sleep apnea syndrome (OSAS), is higher in obese children and adolescents. In fact, OSAS affects 13–59% of obese children and the severity is strongly associated with weight excess. Although overnight pulse oximetry (PO) can be used for diagnosing OSAS, a complete night polysomnography (PSG), which re...

Obesity is increasing, and the related complications are well known. Clinical Trials related with specific diets are currently lacking in paediatrics. There is an increasing interest in Mediterranean diet (MD). The Med4Youth European study* has enrolled 240, 13- to 16-year-old subjects with a BMI above the 90th percentile(WHO curves) in a multicenter randomized controlled trial (Italy, Spain and Portugal) to evaluate the effects of MD. We present the data relative to the 80 su...

CHOPS syndrome is a rare monogenic disorder caused by heterozygous gain-of-function variants in AFF4. The 13 patients reported to date share a highly recognizable phenotype: Coarse face, Cognitive impairment, Heart defects, Obesity, Pulmonary involvement, Short stature and Skeletal dysplasia. AFF4 encodes a scaffold protein involved in transcriptional elongation and critical for gene expression regulation during embryogenesis. Notably, it appears to regulate adipogenic differe...

We report and discuss a case of a girl who at birth underwent surgery for Hirschsprung Disease (HD). To closely investigate her condition, we used a Next Generation Sequencing (NGS) panel to carry out a study of some of the genes known as being associated with congenital megacolon (PHOX-2B, RET, EDN3, GDNF, ASCL1 and BDNF). This analysis showed a maternally inherited heterozygous variant in the RET protooncogene (c.734T>A, p.Val245Glu), which is not described in the scienti...

Objective: Advanced glycation end products (AGEs) increased oxidative stress and promote inflammation, resulting in the cellular damage, by interacting with their receptor (RAGE) on cell membrane. By contrast, the soluble receptor for AGE (sRAGE), that is proteolytically cleaved from cell surface receptor via matrix metalloproteinases, sequester RAGE ligands and act as a cytoprotective and anti-inflammatory agent. AGEs-RAGE/sRAGE interaction is deemed to play a role in the pat...

Background: Klinefelter syndrome (KS) has long-term consequences on bone health. However, studies regarding bone status and metabolism in childhood and adolescence are very rare.Objective and hypotheses: The purpose of our study was to evaluate bone status and metabolism in a cohort of KS children and adolescents.Method: This cross-sectional study involves 40 (mean age 13.7±3.8 years) KS children and adolescents and 80 age-mat...

Background: However, no study has considered the effect of a supernumerary X chromosome on bone mineral status and bone metabolism.Objective and hypotheses: To evaluate bone mineral status and metabolism in a cohort of patients with nonmosaic triple X syndrome.Method: Nineteen girls (median age 10.9, range 7.7–15.9 years) with nonmosaic triple X syndrome were cross-sectionally studied and compared to an age- and body-size-matc...
