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: Imprinted genes are known to regulate fetal growth and a ‘parental conflict’ model predicts that paternally and maternally expressed imprinted genes promote and inhibit fetal growth, respectively. GNAS is a complex imprinted locus with multiple oppositely imprinted gene products. Maternal, but not paternal, G(s)alpha mutations lead to obesity in pseudohypoparathyroidism type IA (PHPIA). However, the disorder rarely causes severe obesity in infancy as pred...

Up to 50% of children born SGA to 2 years have not made a proper catch up (by excess or defect), with repercussions in size, metabolic and cardiovascular disorders, DM, etc. epiPEG-PreMeb project to study during their first two years of life.Goals:: Establish a SGAcohort for monitoring, evaluation catch-up, and analysis of medium-environmental and social factors. To study the influence of these variables on clinical, laboratory and metabolic profiles. So...

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: Accumulation of fat mass in the development of obesity may result from hypertrophy and/or hyperplasia and is frequently associated with adipose tissue (AT) dysfunction in adults. However, the onset and mechanisms of AT dysfunction are not entirely understood.Objective and hypotheses: We assessed composition, function, lipolysis, and inflammation in 171 AT samples from lean and obese children and adolescents (aged 0 – 18 years) to evaluat...

Background: Loss-of-function of immunoglobulin superfamily member 1 (IGSF1) results in an X-linked syndrome of central hypothyroidism and macroorchidism, variable prolactin deficiency, GH deficiency, increased fat percentage, and delayed puberty testosterone rise despite normal timing of testicular growth.Methods: We investigated the spatial and temporal expression of IGSF1 at the protein and mRNA levels in fetal, neonatal, and adult Wistar rats, using i...

Background: Type 1 diabetes mellitus (1DM) is a common chronic disease of childhood. Treatment targets the best metabolic control in order to prevent long-term complications.Objective: To evaluate metabolic control in children and adolescents with 1DM along the years. Methods: Retrospective study including 1DM children and adolescents with more than 2 years of disease. Data were collected at 2005 and at 2012: sex, age at diagnosis, therapy in the last ye...

Introduction: The proopiomelanocortin is a polypeptide of many biologically active peptides involved in many key functions which have not yet been clarified. The mutation in the gene encoding this polypeptide is associated with a clinical trials characterized by early-onset obesity, terciary adrenal insufficiency, and alteration of pigmentation. Eight cases with known genetic mutation have been published.Case report: Newborn male 27 days old from North A...

Introduction: The extracellular calcium-sensing receptor (CaSR) enables the parathyroid glands and other CaSR-expressing cells involved in calcium homeostasis to sense alterations in calcium serum concentrations. Mutations in the CASR gene may produce gain or loss in its activity. Activating mutations cause a hypocalcaemic syndrome of varying severity, as autosomal-dominant hypocalcaemia or Bartter’s syndrome.Case report: We describe a 6 months infa...

Background: Up to 50% SGA did not do a proper catch up (for over/under) and may have implications in size, metabolic, cardiovascular. Arises: epiSGA – PreMeb Project. Global approach to study.Objective: Create clinical cohort of SGA for monitoring, assessment catch-up, use GHRH requirements, environmental/social factors and variables influence on clinical, laboratory and metabolic profiles in order to progress in the knowledge of natural history.
