Objectives: -To determine children diagnosed with central congenital hypothyroidism (CCH) by a screening program using TSH and total T4 between May 2016 and January 2019.-To analyze the characteristics of the disease in these children.Material and Methods: During the time of the study, 14.743 newborns have been screened. Cut-off points are used for TSH ≥10MU/ml and T4 6 and 20 mg/dl as lower ...

Background: Activation of the Wnt/β-catenin pathway is frequent in adrenocortical tumors (ACTs). This pathway and DAX1, a negative regulator of SF1 expression, control adrenal stem/progenitor cells, which can be involved in ACTs formation.Objective: To analyse the association between the Wnt/β-catenin pathway and the expression of a stem cell marker (NANOG), STAT3, DAX1 and SF1 in ACTs.Methods: Patients:...

Background: Severe deficiency of 11β-hydroxysteroid dehydrogenase type 2 (11βHSD2) triggers activation of mineralocorticoid receptor (MR) by cortisol and causing apparent mineralocorticoid excess (AME) syndrome characterized mostly by low-renin arterial hypertension and hypokalemia. In 2003, we studied a patient with AME (3 years-old) having two homozygous mutation, D223N (rs121917833) and a SNP C>T in intron 3 (rs376023420) (Carvajal et al. JCEM 2003).<p cla...

Introduction: Autoimmune Polyglandular Syndrome Type I (APS1) is a rare condition caused by mutations in the AIRE gene (autoimmune regulator). The diagnosis is challenging and delayed due to its non-specific clinical manifestations such as candidiasis, hypoparathyroidism and hypoadrenalism. More than a hundred mutations of this gene have been described and hereby we present a girl who was found to have a novel mutation of AIRE gene with patho...

The main role of the acid-labile subunit (ALS) is to stabilize the IGFBP3/IGF complexes. Pathogenic variants in the gene coding for ALS (IGFALS) results in IGF1 and IGFBP3 deficiency, short stature, delay puberty and insulin resistance. The aim of these study was to identify the genetic cause in a patient with suspected ALS deficiency. The proband is the third son of non-consanguineous parents, evaluated for the first time at 17.3 years due to short stature (−2....

Adrenocortical tumours are a rare disease in the paediatric population, with a higher prevalence in children under 5 years. The aetiology is partially known; in some cases it is related to mutations in the tumour suppressor gene p53 (TP 53). The classical symptoms of the Cushing syndrome are not usually present in children, so we should suspect this disease in children and teenagers with obesity or with slow growth velocity.Methods: We report a case of a...

Currently in Spain, treatment with GH is approved for hospital use with different formulations (JM), multidose vials (VM) and systems with electronic self-injection devices (DE). The long-term treatments, involves the lack of adherence to GH in pediatric patients, it has been estimated a lack of adherence between 5 and 82%. The main objective of this study is to perform a comparative analysis of costs and product loss among the different GH presentations approved in Spain in p...

Background: Apparent mineralocorticoids excess syndrome (AME) is an unusual cause of hypertension, caused by genetic mutation of type 2 11β-hidroxysteroid desydrogenase (11BHSD2) enzime, which metabolizes cortisol(F) to cortisone(E). Patients with AME born from consanguineous parents, are small for gestagional age (SGA) and could have nephrocalcinosis, hypokalemia and high plasma cortisol/cortisone relation (F/E).Objective: To tell the clinical and ...

Background: Promotion of high pick bone mass is one of the strategies to prevent osteoporosis in adult life. Undergraduate students are still in the age group of mineral acquisition and, therefore, their lifestyle may influence this process. Physical exercise is an important lifestyle characteristic for optimize peak bone mass (PBM).Objective: To evaluate bone mass in undergraduate students with different lifestyle.Methods: Observa...

Background: Exercise programs are related to the anabolic function of GH/IGF-I axis.Objective and hypotheses: To analyse IGF-I, IGFBP-3 and ALS serum concentrations in adolescent swimmers at different stages of training season, and compare them with physical performance and body composition.Method: Nine male athletes, aged 16–19 years, who trained regularly throughout the season, were studied. IGF-I, IGFBP-3 and ALS were recor...
