Background: Although the theoretical impact of small in weight and/or size at birth (<2 SDS for EG) is 3–5% (3.5% in the Basque Country (source: Local Government) the socio-economic situation in our country has conditioned a change in its l although 50% at 2 years did not do a proper catch up (by excess or defect) with potential impact on future size and metabolic complications, cardiovascular require specific monitoring.Objective: To assess soc...

Background: During the 1st months of postnatal life serum luteinizing hormone (LH) levels in girls are lower than in boys. The mechanism of this sex difference is not known. It has been proposed that foetal or perinatal androgenic steroids have an effect on the control of LH secretion.Objective and hypotheses: To study the possible influence of high levels of androgens on serum gonadotropins during the 1st months of life in a cohort of nine 46,XX testicu...

Background: Humanin is a novel signaling peptide which has been showed, by in vitro and in vivo studies, to improve insulin sensitivity. As plasma humanin levels decrease during adulthood, particularly during aging, it has been proposed that the increment of insulin resistance in aging might be associated with lesser humanin plasma values.Objective and hypotheses: The physiological insulin resistance observed during puberty in normal ch...

Background: SGA cohort study in analytical and metabolic variables at 3 and 12 months of age with somatométrica situation.Material and methods: Live births in singleton pregnancies in our hospital during 2012–2014, PEG were studied according EG and weight/height (Spanish Tablas 2008). Tours are conducted at 0, 3, 6, 9, 12 months, with measurements of weight, height and perimeter. Blood samples are obtained at least fasting discussed 4h and exce...

Background: Cohort SGA in North of Spain – EPIPEG.Objective and hypotheses: Establish a SGA cohort for monitoring, assessment catch-up, and analysis of middle-environmental and social factors.Method: We study live births in singleton pregnancies in our hospital during 2012–2014, and are classified according age gestation (EG) and weight/height (Spanish growth 2008). Visits were made at 0, 3, 6, 9, 12 months, with measurem...

Background: Congenital growth hormone deficiency may be isolated (IGHD) or multiple pituitary hormone deficiency (MPHD). The Sonic Hedgehog signalling (SHH) pathway has an important role in the pituitary development and growth, acting early in ventral forebrain. The SHH signalling mediates its effects through three zinc fingers proteins (Gli1, Gli2 and Gli3), which lead to activation or repression of target genes. Several heterozygous GLI2 mutations have been reported in patie...

Background: There is preliminary evidence that adrenal steroids other than cortisol may be valuable biomarkers for major depressive disorder (MDD). So far, studies have been conducted in adults only, and conclusions are limited, mainly due to small sample sizes. Therefore, the present study was intended to assess whether adrenal steroids (progesterone, 17-hydroxyprogesterone, 21-deoxycortisol, 11-deoxycortisol, cortisol, cortisone, deoxycorticosterone, cortico...

Background: There is a distinct increase in the prevalence of depression with the onset of puberty. The role of peripubertal testosterone levels in boys in this context is insufficiently understood. Moreover, the number of CAG repeats of the androgen receptor gene (AR) and the depression status (subclinical vs. overt depression) may modulate the role of testosterone, but this has not yet been studied in a clinical sample.Methods:...

Introduction: The melanocortin 4 receptor (MC4R) is a G protein coupled receptor (GPCR) and plays a pivotal role in the central regulation of body weight in the hypothalamus. In the context of the leptin-melanocortin signaling pathway, the MC4R is activated by the endogenous ligands a- and b-MSH (melanocyte-stimulating hormone). This leads to the feeling of satiety and to a reduction in food intake. Mutations within the genes leptin, leptin receptor (LEPR), pr...

At present no European recommendations for the management of pediatric thyroid nodules and differentiated thyroid carcinoma (DTC) exist. Differences in clinical, molecular, and pathological characteristics between pediatric and adult DTC emphasize the need for specific recommendations for the pediatric population. An expert panel was instituted by the executive committee of the European Thyroid Association (ETA) including an international community of experts from a variety of...
