Background/Aims: 46,XY gonadal dysgenesis (GD) is classified as complete (CGD) or partial (PGD) depending on gonadal morphology and function. In contrast to the typical female external genitalia in CGD, the phenotype of PGD is variable depending on androgen production. A diagnosis of PGD is based on clinical/biochemical features, gonadal histology and genetic findings. The aim of this study is to characterise these features, particularly histological, in a lar...

Introduction: Homozygous leptin (LEP) and leptin receptor (LEPR) mutations lead to childhood-onset obesity due to deficient leptin signaling. The specific aims of this work are to explore genotype/phenotype correlations in a national multicenter cohort of 18 subjects with leptin (LEP) and leptin receptor (LEPR) deficiency, report on the long-term clinical follow-up of these rare cases, and systematically review all patients with pathogenic <e...

Background: The need to understand the relationship between bone, muscle, and fat within the bone-muscle unit has recently gained great prominence. Although high resolution (HR) MRI is a non-invasive imaging modality that can provide this information, there is limited expertise in children and young people.Objectives: To establish MRI-based normative data for bone, bone marrow adiposity and muscle adiposity in children a...

Introduction: Craniopharyngiomas (CP) are rare pediatric intracranial tumors (1.2-4%) with a peak of incidence between 5-14 years . We retrospectively reviewed data of 16 cases (M/F 4/12) diagnosed before 4 years of age (median follow up 7.2 years) from a cohort of 117 patients (pts) (M/F 56/41) diagnosed after 01/01/2000, followed-up in 14 Italian centres of pediatric endocrinology belonging to the Italian Society for Pediatric Endocrinology and Diabetolo...

Disorders/differences in sex development (DSD) are defined as congenital conditions in which development of chromosomal, gonadal or anatomical sex is atypical. 46,XY DSD include defects in androgen synthesis or action or complete (CGD)/partial (PGD) gonadal dysgenesis. The aim of this study was to characterize the molecular genetic diagnosis of individuals with 46,XY DSD followed at Garrahan Pediatric Hospital.Medical records of 140 patients (P) followed...

We evaluated the effect of GFD on the growth of children with the classical form of CD on long-term GFD (> 2 years).Methods: We studied growth parameters (weight gain/day, BMI and BMISDS, HtSDS) and lab data for 30 prepubertal children aged 8.5 years +/−3 years with CD, who were on GFD since the age of 3.4 years +/−2.6 years (> 2 years on GFD) for duration of 1 year. The anthropometric data of 30 randomly sele...

Background: Insulin-like growth factor I (IGF-I) is one of the important hormonal mediators of human growth. Circulating IGF-I exists in a ternary complex bound to the acid-labile subunit (ALS) and one of its six binding proteins (BPs). IGF-I bound to ALS and BPs needs to be liberated by either Pregnancy Associated Plasma Protease A (PAPP-A) or A2 (PAPP-A2) to reach its receptor. Stanniocalcin 2 (STC2) is a potent inhibitor of both PAPP-A and PAPP-A2. Genome-wide association s...

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: Anogenital distance (AGD) is an indicator of androgen action in utero. Reduced AGD has been found in males with hypospadias, cryptorchidism, low semen quality and infertility. Its usefulness as a clinical marker in patients with Disorders of Sex Development (DSD) is currently being investigated. However, detailed age, sex and method related reference ranges do not exist. Whether individual (body-size-adjusted) AGD is stable postnatally also remains to be e...

Background: Low stress resilience in late adolescence and psychosocial traumatic events in adulthood have been linked to a higher risk of developing type 2 diabetes (T2DM) later on in life. However, limited data is available regarding whether prior stressors are related to the risk of developing T2DM in adolescence.Objective: We sought to determine the potential association between prior toxic stressors and T2DM in adolescence.Desi...
