Background: Management of subclinical hypothyroidism (SH) in infancy is still controversial. According to the European Guidelines for Congenital Hypothyroidism (CH), in case of TSH levels between 6 and 20 µUI/ml, both levothyroxine (L-T4) therapy and a wait-and-see approach can be considered.Aim: to describe the evolution of SH diagnosed in newborns recalled by neonatal screening (TSH values ≥7µUI/ml)....

Introduction: Children with classic congenital adrenal hyperplasia due to 21-hydroxylase deficiency (CAH) require glucocorticoid (GC) therapy to replace cortisol insufficiency and reduce excess adrenal androgens. Supraphysiological GC doses are typically required, predisposing patients to GC-related comorbidities. In Phase 2 studies, participants with CAH who received crinecerfont, a novel oral CRF1 antagonist, experienced reduction of the adrenal a...

Background: Genetic causes of central precocious puberty (CPP) has been increasingly recognized, extending our knowledge of the triggering factors of human pubertal timing. Distinct etiologies remain to be elucidated in sporadic and familial cases. Methyl-CpG-binding protein 2 (MECP2) is a chromatin-associated protein that can activate or repress gene transcription, playing a role in neuronal maturation. It is encoded by MECP2 gene located at chromoso...

Background: Electrolyte imbalance is often encountered in hospitalized patients, with hyponatremia being the most frequent and potentially the most diverse in regards to its etiology, with endocrine causes representing a high proportion. However, the prevalence of hyponatremia in the general pediatric population is still unknown, as the available studies have focused on admitted patients in acute conditions.Aim: The aim ...

In children with XLH, excess FGF23 causes hypophosphatemia with consequent rickets, skeletal deformities, and impaired growth and mobility. We previously reported that burosumab improved phosphate homeostasis and rickets in children with XLH. Here, we report final data from this Phase 2 Study CL201 (NCT02163577).Fifty-two children with XLH (5-12 years old, Tanner ≤ 2) were randomized 1:1 to receive subcutaneous burosumab every 2 (Q2W) or 4 (Q4W) we...

In children with XLH, excess FGF23 causes hypophosphatemia with consequent rickets, skeletal deformities, and impaired growth and mobility. We reported that burosumab improved phosphate homeostasis and rickets in children with XLH. Here, we present data on 11/52 subjects (all girls) who developed fused growth plates during the phase 2 study CL201 (NCT02163577).In CL201, 52 subjects (Baseline: 5-12 years-old, Tanner ≤ 2) were randomized 1:1 to recei...

Achieving adequate glycaemic control in children with type 1 diabetes (T1D) is essential to reduce incidence and progression of microvascular and macrovascular complications. However, factors that influence glycaemic control remain to be understood. The present study aimed to evaluate clinical, personal, genetic and eating behaviour characteristics underlying glycaemic control in T1D. 325 T1D individuals aged 6 and 20 years and with at least 1 year of disease duration have bee...

Achondroplasia is a rare genetic condition caused by a recurrent pathogenetic variant in the FGFR3 gene resulting in short limb skeletal dysplasia. Due to the wide-ranging anomalies associated with achondroplasia (both peculiar clinical features and complications), a multidisciplinary team is often required for ongoing care, although the nature of specialists involved differs among countries. Despite a European consensus on principles for the management of achondropla...

Background: Central precocious puberty (CPP) is defined as the secondary sexual characteristics onset before 8 years of age in females and before 9 in males, due to premature activation of the hypothalamic-pituitary-gonadal axis. The underlying cause remains idiopathic in the great majority; based on the 2009 Consensus, 2% to 7% of girls who have onset of CPP between the ages of 6 and 8 years have unsuspected pathology and only 1% have a tumor such...

Background: Obesity is a persistent disorder that almost universally recurs following treatment, suggesting a disruption on central nervous system control over energy homeostasis. Recent literature suggests that hypothalamic inflammation may have an important role on obesity pathogenesis. This inflammatory reaction, which histologically appears as a reactive gliosis, may be detected using magnetic resonance imaging (MRI), and has just been shown in rodent models and adults.</p...
