Background: Puberty is associated with a physiological decline in insulin sensitivity. Overweight and obesity are common among girls with Central Precocious Puberty (CPP). CPP and early menarche have been considered as risk factors for obesity and cardiovascular diseases during adulthood. Besides, concern has been raised by the potential impact of GnRH analogues (GnRH-a) treatment on body weight and metabolic profile.Objective and hypotheses: To evaluate...

Introduction: Gliomas are the most common solid tumours during childhood. In children with neurofibromatosis Type 1 (NF1) and optic pathway glioma (OPG), growth hormone excess has been described. However, this phenomenon has not been reported in children with OPG without NF1. We aimed to describe the growth and IGFs/IGFBP3 levels in a large cohort of paediatric patients with non-NF1- associated central nervous system (CNS) tumours.Method...

Background: Human IGF1 gene defects are characterized by intrauterine and postnatal growth retardation, sensorineural deafness, microcephaly and intellectual disability. Seven cases have been reported so far, and the underlying pathophysiology has been characterized in only three.Objective: To describe a patient with severe short stature presenting a novel homozygous IGF1 gene mutation and its underlying pathogenic mechanism.<p clas...
