Background: A new classification of pseudohypoparathyroidism is available (Thiele et al. 2016, J Endocrinol). The phenotype variability of inactivating PTH/PTHrP Signaling Disorders (iPPSD, former pseudohypoparathyroidism) cases is still very challenging, even for experts. Thus, it is crucial to collect data in a centralized manner for future investigation.Methods: The EuRRECa/EuRR-Bone registries are the first ...

Introduction: The CCDC3 gene encodes for a protein expressed in endothelial cells and adipose tissue. Insulin increases its expression and, in turn, CCDC3 positively regulates adipogenesis and lipid accumulation. CCDC3 expression is increased in visceral adipose tissue from subjects with obesity. Gestational obesity can modify the metabolic programming in the offspring through epigenetic mechanisms. However, it is unknown whether the...

Introduction: Thyroid cancer is the most common pediatric endocrine cancer, constituting 0.5%–3% of all childhood malignancies. Cancer can be present in multinodular thyroid disease but the majority of malignant nodules are solitary. Thyroid malignancies in children are almost always well differentiated.Aim: Prevalence, clinical features, pathological profile and therapy of thyroid cancer in children.Patients and method: Retro...

Background: G, male, was born at 39 GW by emergency CS from non-consanguineous parents. Prenatal US showed growth at lower limits of normal from 22 GW, short limbs and polyhydramnios. Amniocentesis karyotype was 46,XY. At birth weight and length were <3rd percentile, head circumference was between 10 and 25th percentile. At physical examination: short limbs, short neck, cryptorchidism, and microphallus. Early the baby presented mild respiratory distress and a severe episod...

Background: Congenital hypopituitarism is a rare disease. Although our understanding of the involved transcription factors is improving, mutations in candidate genes are rarely identified. Extra-pituitary symptoms can point towards new genes of interest. FOXL2 is mutated in blepharophimosis/ptosis/epicanthus inversus syndrome (BPES), a rare affection that combines congenital alterations of eyelids with ovarian dysgenesis in some families. Moreover, we have previously reported ...

The obesity epidemic continues to be a dramatic problem in the developed world despite attempts to curtail its rise. Reducing energy intake and/or increasing energy expenditure can result in weight loss; however, if one returns to their poor lifestyle habits the previous weight is not only recuperated, but often surpassed.We hypothesized that although a normal body weight may be achieved, the hypothalamic circuits controlling appetite and energy expendit...

The insulin-like growth factor (IGF) system is fundamental for physiological processes such as growth and metabolism. In addition, in the brain it regulates glucose metabolism and neuroprotection. The IGF axis can be altered by nutritional status, but little is known regarding the effects of specific dietary components on this system.Our aim was to examine how high-fat diet (HFD) and low-fat/high sucrose diet (LFHSD) intake affect the central and circula...

Introduction: The dichotomous nature of the definition of Metabolic Syndrome (MS) in both children and adults can under-diagnose subjects at risk and prevents adequate follow-up of therapeutic interventions. Recently, a continuous score of MS (sSMp) was validated in the pediatric population based on the IDF criteria for a population> 16 years.Objectives: To apply sSMp in a Chilean pediatric population cohort and corr...

Background: The diagnosis of GH deficiency in children is based on clinical, auxological, radiographic and biochemical criteria which include response to Pharmacological Estimulation Tests (PhT). It is well known that GH concentrations vary according to the assay method used. Currently in our population, the proposed cut-off value of serum GH PhT is 4.7 ng/ml measured by ICMA using the IRP 98/574.Objective and hypotheses: The aims of this study were to d...

Background: It is well known that ingestion of a high fat diet (HFD) can induce rapid weight gain and metabolic imbalances. However, males and females are not equally susceptible to these effects. Furthermore, an individual may be more prone to gain weight during specific developmental periods.Aims and objectives: We aimed to analyse the response to the acute exposure to a HFD during pubertal/adolescent period and to determine whether males and females r...
