Objetives: To analyse clinical and laboratory characteristics of an obese pediatric population.To assess their response to specific program consisting in modification of their nutritional habits and physical activity .Material and Methods: Obese patients completed a year of group therapy with nutritional education and physical activity. We analysed at the beggining and after a year anthropometry an...

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: Newborn (NB) screening programs show a wide variation in congenital hypothyroidism (CH) incidence along the years.Objective and hypotheses: To describe CH incidence, etiology, associated malformations and Down Syndrome (DS) in children detected by our NB Screening Program. To search differences between permanent CH (PCH) and transient forms (TCH).Method: We analyzed NB with positive screening results referred between A...

Background: Insulin/IGF1 signaling plays a critical role in central glucose bioavailability and lipid metabolism. An increase in glucose disposal can generate reducing agents through the pentose-phosphate pathway necessary for the synthesis of free fatty acids (FFA). Disturbances in lipid synthesis are related to the appearance of insulin resistance and diabetes. The insulin receptor substrate 2 (IRS2) deficient mice (IRS2−/−) is an excellent model to st...

Background: Non-classical congenital adrenal hyperplasia (NCCAH) may present during childhood, adolescence or even adulthood with various degrees of hyperandrogenism. Diagnosis is established through tetracosactide (Synacthen®) test and genotyping. Cortisol insufficiency has rarely been described in NCCAH.Objective and hypotheses: To describe cortisol response to tetracosactide test in NCCAH patients.Method: Retrosp...

Background: Androgen insensitivity syndrome in its complete form (CAIS) is a disorder of hormone resistance characterised by a female phenotype in an individual with an XY karyotype and testes producing age-appropriated normal concentrations of androgens. Pathogenesis is the result of mutations in the x-linked androgen receptor (AR) gene, which encodes for the ligand-activated AR. We report the clinical, biochemical and molecular features of two affected sisters in whom a nove...

Background: Short stature may be a source of social and affective stress in children and their parents, and thus impact negatively on their quality of life (QoL). Treatment by GH may improve QoL through normalisation of height.Objective: To evaluate height-specific QoL in short stature children after 1 year of GH treatment.Methods: Prospective study. Inclusion criteria were: having started GH treatment at Hôpital Necker-Enfant...

Of the 67 included DSD patients, 33% were HSCs. 68% women and 32% men, with a total concordance between legal sex, current gender and chromosomal sex. Median age: 10.5 years, IQR 8-14. The most frequent clinical form was non-classical (NC) 45.5%, followed by classical with saline loss (CPS) 41%. The distribution of each clinical form according to the karyotype is significant (P = 0.013), the most frequent with XY karyotype is CPS and in NC forms all cases are XX. Med...

Body Mass Index (BMI) has a high association with body fat percentage and direct association with a higher degree of comorbidities. Categorizing patients only by the degree of obesity, as has been done over time, restricts the possibility of detecting and giving timely treatment to other aspects. The Edmonton Obesity Staging System for Pediatrics (EOSS-P) has been proposed as a tool to categorize obesity not only by BMI, but also by assessing metabolic complications, functiona...
