Background: Type 2 diabetes (T2D) is an emerging disease in the pediatric population. The association between T2D and non-alcoholic fatty liver disease (NAFLD) has been described; the mechanisms responsible for the development and progression of NAFLD are incompletely understood. Evidence of high Haemoglobin A1c (HbA1c) levels and the risk of diabetes complications has been demostrated. Recent evidence suggests that metabolic control may have a role in the dev...

Introduction and Aims: Autosomal dominant hypocalcemia or type V Bartter syndrome is characterized by hypocalcemia, low parathyroid hormone (PTH), and calciuria, which marks its prognosis due to the risk of nephrocalcinosis. It is caused by activating mutations in the calcium-sensing receptor (CASR) gene (3q21.1), which is expressed in the parathyroid and renal tubules, causing salt and potassium loss, due to the inhibition of the ROMK and NKCC2 channels. We s...

Background: We have recently reported a BMI-SDS increase in girls with Turner syndrome (TS) treated with growth hormone (GH) (1).Objective and hypothesis: We hypothesise that puberty induction in TS is associated with weight gain.Method: We analysed the weight changes (BMI-SDS) of 888 girls with TS in the Pfizer International Growth Database (KIGS). Overweight was defined by a BMI >90th percentile and obesity by a BMI >97th...

Background: Type 2 diabetes (T2D) is an emerging disease in the pediatric population. The mechanisms responsible for the development of nonalcoholic fatty liver disease (NAFLD) and progression to nonalcoholic steatohepatitis (NASH) in these patients are incompletely understood. Low serum insulin-like growth factor-1 (IGF-1) levels are associated with increased histologic severity of NAFLD. Growing evidence suggests that growth hormone (GH) and IGF-1 may have r...

Background: Type 2 diabetes (T2D) is an emerging disease in the pediatric population. The association between T2D and non-alcoholic fatty liver disease (NAFLD) has been described; this increases the risk of coronary heart disease (CHD). Recent evidence suggests that sizes and composition of HDL may be more important that HDL-C levels in predicting CHD. There is not data regarding the HDL subclasses distribution and composition in T2D youths with hepatic steatosis (HE).<p c...

Introduction: Recombinant GH is an effective treatment for short children who are born small for gestational age(SGA). Short children SGA who fail catch-up growth by 4 years of age are candidates for GH treatment, at a dose of 35–70 μg/kg per day. Factors associated with response to GH treatment during the initial 2–3 years of therapy include age and height standard deviation scores at the start of therapy, midparental height, and GH dose. It is important to kno...

Background: AuxoLog is a validated computer program that evaluates auxologic parameters comparing them with the Spanish growth charts. It also allocates subjects to the corresponding pubertal development group.Objective: To assess the evolution of auxological parameters in GH deficient (GHD) pre pubertal children treated with Omnitrope for a minimum of 2 years prior to puberty.Method: This study is non-interventional, retrospective...

Background: The interrelationships between body weight and thyroid status are complex. Serum TSH is typically increased in obese compared with lean individuals. Several mechanisms leading to hyperthyrotropinemia have been hypothesized.Objective and hypotheses: To compare thyroid function and autoimmunity in normal, overweight and obese healthy children and adolescents in our population. To analyse any metabolic risk factor related to hyperthyrotropinemia...

Differences of sex development (DSD) occurs when the development of chromosomal sex, gonadal or internal/external genitalia is atypical. It has an incidence of 1: 1000-4500 live born children. New chromosomal array technologies (SNP-array) can analyze the genome of the individual providing information of copy number variation (CNV) of specific chromosomal regions helping to identified pathogenic variants that could explain the etiology of the DSD. This study aims to analyze th...

Introduction: Pilocytic astrocytoma is the most common type of CNS astrocytoma in children. Clinical manifestations depend on its location and size and initial symptoms are usually related to neurological deficits or signs and symptoms of intracranial hypertension. Involvement of the hypothalamic area, pituitary infundibulum and leptomeningeal spread are exceptional. The case of a patient with central precocious puberty in whom the initial neuroimaging study oriented the diagn...
