Introduction: Familial glucocorticoid deficiency (FGD) is a rare autosomal recessive disease characterized by ACTH-resistant isolated cortisol deficiency. FGD usually presents with hypoglycemia, convulsions, prolonged jaundice, and marked skin hyperpigmentation in the early period of life. Several defects in MC2R, MRAP, MCM4, NNT, and TXNRD2 genes are related to FGD. In all these situations, plasma ACTH is high. By contrast, all reported cases of glucocorticoi...

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...

Background: Sulfonylurea therapy (SU) allows a better metabolic control than insulin in patients with neonatal diabetes secondary to mutation in potassium channel subunits (ND-K). Most of these patients have neurological and neuromotor developmental impairments whose changes under SU has not been studied in a systematic and prospective way in a large cohort.Objective and Hypotheses: To demonstrate the beneficial effect of SU on neuropsychological functio...

Background/Objective: Smoking during pregnancy is known to influence prenatal/postnatal growth of the offspring. We investigated the impact of smoking in the Swedish reference population for new reference for height, weight and BMI, the GrowUp1990Gothenburg cohort.Material/Methods: The study was based on 1907 healthy children (918girls/989boys) born at term in Sweden with Nordic parents and longitudinal growth measurements. 155girls/180b...

Aim: Hypophosphatemic rickets (HR) is a rare renal phosphate wasting disorder commonly related to X-linked form, caused by PHEX mutations and it treatment and follow-up is challenging due to imperfect treatment options. Here we presented nationwide data on HR with initial and follow-up data on the patients presented to the pediatric endocrinology clinics before the age of 18 years.Results: From 24 centers, 158 patients (93 male/65 female) were i...

Background: Hypothalamic obesity (HO), due to midline congenital malformations, genetic diseases or hypothalamo-hypophysis tumours, is severe and difficult to treat. Patients are scarcely compliant to diet and physical activity, for disabilities often affecting them. Drugs have been rarely employed.Objective and hypotheses: Aim of the study was to treat hypopituitaric children and adolescents affected by severe HO with a multidisciplinary approach includ...

Background: An important issue in the management of congenital hypothyroidism (CH) is the best initial dose of levothyroxine (L-T4) in order to achieve optimal neurocognitive outcomes. Both European and American guidelines suggest an initial dose of 10–15 μg/kg per die but trials on long-term effects of different doses within this range are lacking.Objective and hypotheses: This was a multicenter randomized trial to ev...

Background: OTX2 is expressed in the human brain and plays a key role in the eye development. OTX2 mutations are reported in patients with ano/microphtalmia, optic nerve or optic chiasm hypoplasia, ocular coloboma and retinal dystrophies, associated in some cases with brain or pituitary abnormalities.Objective and hypotheses: Most of OTX2 mutations are nonsense or frameshift, more rarely missense mutations occur.Method: We...

Background: Puberty is characterised by important changes of brain networks. The glutamate system plays a main role in modulating the onset of puberty as shown for NMDA receptor agonists. However, the underlying mechanisms are poorly understood. Metabotropic mGlu5 receptors (mGluR5) are tightly linked to NMDA receptors. The effect of mGluR5 blockade on neurohormonal mechanisms in puberty initiation were not studied yet.Objective and hypotheses: To invest...

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...
