Background: The first three children reported to have biallelic mutations in RNPC3 presented with growth hormone (GH) deficiency and pituitary hypoplasia (MIM#618860). RNPC3 codes for a minor spliceosome protein required for U11/U12 small nuclear ribonucleoprotein formation and splicing of U12-type introns. The underlying mechanism causing GH deficiency in these patients is not fully understood. Moreover, whether the association of further ho...

Introduction: Transient hyperinsulinism is described in neonates with stress factors (intrauterine growth restriction (IUGR), large for gestational age (LGA), perinatal asphyxia, infants of diabetic mother etc.). Recognition and early treatment is prioritary to avoid neurological morbidity related with recurrent hypoglycemia.Objective: Describe the incidence of transient hyperinsulinism. Clinical charac...

Introduction: In the last years, the prevalence of high blood pressure (HBP) has increased in children, contributing to raise the risk of future cardiovascular disease. It is known that family history, pregnancy characteristics and type of feeding in the first months of life are of great importance in the prevention of diseases in the offspring. In this study we aimed to investigate the association between early life risk factors and HBP in children and adolescents.<p clas...

Background: We recently reported three children with severe isolated growth hormone (GH) deficiency and pituitary hypoplasia due to biallelic mutations in the RNPC3 gene, which codes for a minor spliceosome protein required for U11/U12 small nuclear ribonucleoprotein formation and splicing of U12-type introns. Although it is clear that these patients are GH deficient, the underlying mechanism for this deficit is not totally understood.Objective:...

Background: Transsexuality during childhood/adolescence is a complex condition usually ending in dysphoria (GD). The prevalence of transgenderism is increasing in Pediatrics. In the process of sexual reassignment, a correct pharmacological treatment and the knowledge of possible consequences are necessary.Objetive: The objective of this study is to present the evolution of the physical and analytical characteristics and side effects in Transgender childr...

Background: Studies aimed at elucidating the pathophysiology of obesity consistently describe it as a highly heterogeneous disorder at both clinical and molecular level. Despite rare monogenic forms and several regions of susceptibility have been defined, the genetic causes underlying the disease remain largely unknown.Objective and hypotheses: We aimed to identify novel genetic abnormalities in a cohort of Spanish children with severe non-syndromic earl...

Background: Isolated growth hormone deficiency is the most common pituitary hormone deficiency, although the majority of cases are idiopathic. The presence of pituitary structural abnormalities may influence growth hormone (GH) deficiency severeness.Objective: Assess the effect of pituitary abnormalities in idiopathic isolated growth hormone deficiency (IIGHD).Methods: We analysed 65 children with IIGHD and pituitary magnetic resso...

Background: Waist circumference (WC) reflects the fat distribution and the degree of central adiposity in children, which is specifically associated with cardiovascular risk factors and useful as a component of metabolic syndrome definition in children.Objective and hypotheses: To evaluate the distribution of WC measures among preschool children aged 3.5–5.5 years from six European countries.Method: Cross-sectional study of a ...

Background: Besides surgery, radioactive iodine therapy (RAI) is an effective and safe option to treat children with hyperthyroidism from Graves disease (GD) who cannot achieve euthyroidism with antithyroid drugs.Objective and hypotheses: To present the experience of a Portuguese paediatric unit with the use of RAI in children with GD.Method: The authors performed a review of 7 cases of Graves disease of age under 18 years treated ...

Background: Type 1 diabetes (T1D) is a T cell-mediated autoimmune disease. A more complex immunological picture is being unraveled, with a key role of innate immune cells at disease onset and maintenance. For new therapies based on immune-modulation to be possible, immune characterization of T1D patients is crucial.Objective and hypotheses: We aimed to characterise innate and adaptive immune cells of T1D children at a well-defined ‘onset-window&#146...
