Background: The pituitary set-point for TSH synthesis and secretion is known to be an individual parameter with a strong genetic influence. Type II iodothyronine deiodinase is a pituitary enzyme involved in local deiodination of T4 and negative feed-back loop for TSH secretion. Defects in DIO2 have not been reported in humans; however, Dio2 knockout mouse has pituitary resistance to T4 with elevated TSH, T4 and TSH/T4 ratio, with nor...

Background: There is increasing interest in vitamin D nutrition during pregnancy because of widespread reports of a high prevalence of low vitamin D status in pregnant women in high-latitude areas. It has been related to adverse events in mother and child. Neonates present a greater risk of hypocalcaemia, rickets and a higher incidence of infections during the 1st year of life.Objective and hypotheses: Real situation of pregnant women and newborn in rela...

Background: The progress made in the treatment of childhood cancer has resulted in better long-term survival rates. Therefore sequelae of treatment have become more important.Objective and hypotheses: To investigate the prevalence of early endocrine disorders in survivors of a childhood tumour within the 1st years after diagnosis.Method: We performed a retrospective medical record review of survivors followed at the endocrine clini...

Introduction: Failure to thrive (FTT) is a common entity encountered by pediatricians. It can be caused by inadequate energy intake or “organic causes” such as inborn errors of metabolism or disorders of the endocrine system. One cause that is rarely seen is a deficiency of aldosterone.Case presentation: A set of 3-month-old monozygotic male twins presented with failure to thrive and dehydration. Initially, they were evaluated ...

Introduction: Children with Small for Gestational Age (SGA) are known to have lower neurocognitive development and an increased in cardiovascular risk in adulthood. 10% of SGA don´t usually do the catch-up and if they meet criteria they have indication to follow Growth Hormone (GH) treatment.Objectives: To establish the difference between SGA diagnosed children who did or did not catch-up (treated with GH), in terms...

Background: Obesity is characterised by excessive fat accumulation coursing with a chronic mild inflammatory state, with adipose tissue (AT) being the main site of increased systemic cytokine production. Increased adiposity early in life is the main risk factor for cardiometabolic disorders later in life, with the abnormal accumulation of lipids in AT leading to the production of pro-inflammatory cytokines. Inflammatory process that involves metabolic and card...

Background: Cardiovascular diseases are the leading cause of premature death among women with Turner syndrome (TS). Studies in youth with TS suggest that cardiometabolic-related dysfunction is present in childhood, however these small convenience samples may not be generalizable to the whole TS population. PEDSnet, the largest pediatric Health Learning System in the United States (US) representing >6 million children, offers a unique opportunity to examine ...

Noonan syndrome is a genetic condition caused by dysregulation of RAS-MAPK pathway (RASopathy) characterized by great clinical variability and genetic heterogeneity. Many genes has been associated with the disease, including recently LZTR1, which is causative of both dominant and recessive forms. Currently less than one hundred cases of Noonan syndrome has been associated with LZTR1 variants then phenotype related to this gene is poorly known. Here we describ...

Mitochondrial diseases are multisystemic disorders which often involve endocrine system, as defective oxidative phosphorylation can lead to decreased hormones production or secretion and all steroid hormones are synthesized in the mitochondria. Endocrine dysfunctions can therefore represent the initial symptoms of these pathologies and the incidence of various endocrinopathies varies between different mitochondrial disease. Diabetes mellitus is the most frequently described en...

Background: Disorders of Sex Development (DSD) are a rare disease often caused by complex genetic mechanisms, with a wide spectrum of clinical manifestations that lead to a continous evolution of the diagnostic classification. From 2002, In the Veneto Region, all DSD diagnoses have been collected thanks to the creation of a Registry for Rare diseases, including DSD.Material and Methods: We could retrospectively analyze t...
