Objectives: Among adverse effects of GH, a particular attention should be given to glucose homeostasis. The aim of the study was evaluate the effect of GH therapy on glucose homeostasis in children with GHD after 10 years of treatment.Methods: 30 patients (8 M/22 F, age 7.00 ± 2.61 years) with GHD at diagnosis and 30 healthy children comparable to patients for age, sex and BMI were enrolled. Glucose, insulin, HOMA-IR ...

Objective: to assess the prevalence of endocrinopathies in a pediatric population of Rett syndrome (RTT) patients.Design: retrospective observational double center study.Methods: 51 caucasian patients (47 girls, 4 boy) with genetically confirmed diagnosis of RTT were enrolled (mean age: 9.65±5.9 years, range: 1-18 years). The patients were referred from the Rett Center of two It...

The Ovotesticular Disorder of Sexual Development (OT DSD) is a rare condition characterized by histologic demonstration of both ovarian and testicular tissue in the same individual. Descriptions in literature usually have small samples and do not include patient evolution data. The aim of this study is to describe clinical, biochemical and histological findings, as well as long-term outcomes (including onset and progression of puberty) in patients with OT DSD, accompanied betw...

Introduction: Noonan syndrome (NS) is a relative frequent genetic disorder, mainly characterized by dysmorphic face features, congenital heart defects and short stature. Though delayed pubertal development has been described in both sexes, the physiopathological root remains unclear. This study aims at characterizing puberty development in Noonan syndrome.Materials and Methods: The study population included 111 individuals with a molecul...

Introduction: Precocious pubarche (PP) is characterized by the early development of pubic hair and clitoral enlargement in girls. While commonly attributed to adrenal-related causes, such as congenital adrenal hyperplasia or adrenal tumors, ovarian sources are infrequent etiologies. In this report, we present a clinical case of a young girl with PP due to a rare source.Case Report: A 1.7-year-old girl presented with the ...

Background: Diabetes insipidus (DI) is characterised clinically by the inappropriate production of large volumes of dilute urine even in the presence of clinical dehydration or deprivation of water. DI occurs either due to a deficiency or insufficiency of arginine vasopressin (AVP) hormone production. Hereditary DI accounts for <10% of the DI cases. As hyponatraemic seizures secondary to inappropriate use of desmopressin can occur, caution is required before a diagnosis of...

Objective: Craniopharyngioma is a benign brain tumour with frequent local recurrence after treatment. Growth hormone replacement therapy (GHRT) is prescribed in children with growth hormone deficiency due to childhood-onset craniopharyngioma. The objective was to evaluate whether shorter time delay of GHRT initiation after childhood-onset craniopharyngioma completion therapy increased the risk of recurrence.Design: Our r...

Purpose: Isolated growth hormone deficiency (IGHD) is a rare condition mainly caused by mutations in GH1. The aim of this study was to assess the contribution of GHRHR mutations to IGHD in a very large cohort of patients.Methods: All GHRHR coding exons and flanking intronic regions were sequenced in 312 unrelated patients with non-syndromic IGHD. Functional consequences of all newly identified missense variants were assessed <e...

Background: GLI2 is a zinc-finger transcription factor of the SHH signaling pathway, expressed during ventral forebrain and pituitary development. GLI2 mutations account for microforms of dominant holoprosencephaly. So far, only 15 unambiguous mutations were found in hypopituitarism –essentially combined pituitary hormone deficiency (CPHD)– frequently associated with holoprosencephaly-like malformations and/or polydactyly.Objective and...

Background: Bi-allelic GHR mutations are classically responsible for Laron syndrome, a severe growth hormone (GH) resistance syndrome. A few GHR missense mutations have also been implicated in mild GH resistance or idiopathic short stature. IGFALS mutations are responsible for recessive or semi-dominant short stature with normal GH provocative test contrasting with extremely low IGF-I levels.Objective and hypotheses: To assess the contribution of GHR and...
