Background: X-linked hypophosphatemic rickets (XLH) is caused by inactivating mutations in the phosphate-regulating gene with homologies to endopeptidases on the X chromosome (PHEX). In this group of patients, data about renal calcifying disorders are scarce.Objective and hypotheses: To determine the prevalence of nephrocalcinosis and nephrolithiasis and their risk factors in XLH patients.Method: 36 patients (15 children a...

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 and Aims: Long chain polyunsaturated fatty acids (LC-PUFA) are essential nutrients for the development of the fetus and are supplied by the mother through the placenta. Omega-6 arachidonic acid (AA) and both omega-3 eicosapentaenoic acid (EPA) and docoshexaenoic acid (DHA) stand out for their functional roles. Recent studies show that the concentrations of these fatty acids in maternal blood and umbilical cord are associated with adiposity in the of...

Introduction: Gliomas are the most common solid tumours during childhood. In children with neurofibromatosis Type 1 (NF1) and optic pathway glioma (OPG), growth hormone excess has been described. However, this phenomenon has not been reported in children with OPG without NF1. We aimed to describe the growth and IGFs/IGFBP3 levels in a large cohort of paediatric patients with non-NF1- associated central nervous system (CNS) tumours.Method...

Background: The pseudohypoparathyroidism (PHP) encompasses a heterogeneous group of clinical entities caused by a defect in the peripheral action of parathyroid hormone (PTH). Biochemically it manifests itself with hypocalcemia, hyperphosphatemia and elevated PTH. PHP-Ia is the most frequent and multiple hormone resistance, associated signs of Albright hereditary osteodisfrofia (OHA) and mutations in the gene encoding GNAS Gsa protein.Case presentation: ...

Background: Antipituitary (APA) and antihypothalamus antibodies (AHA) have not been investigated in children and adolescents with brain tumors.Patients and Methods: Sixty-three patients with craniopharyngioma, glioma and germinoma treated with surgery and/or chemotherapy and/or radiotherapy were evaluated at a median age of 13 years. Forty-one had MPHD, 6 had a single defect being GH the most common (65.1%), followed...

Background: The diagnosis of 46,XY disorder of sex development (DSD) due to 5-alpha reductase 2 (5α-RD2) deficiency has been based on testosterone:dihydrotestosterone (T:DHT) ratio, urinary steroid profiling and mutational analysis of SRD5A2 gene. The biochemical hallmarks of 5α-RD2 deficiency include increased T:DHT ratio. However, several difficulties are observed in the DHT measurement leading to misdiagnosis. The mutational analysis of the SRD5A2 has been propose...

Background: Hashimoto’s thyroiditis (HT) has been linked to papillary cancer in adults but not in children and adolescents. Moreover, there is no agreement on the more appropriate frequency of thyroid ultrasound (TS) in the follow-up of children with HT.Objective and hypotheses: The aim of the study was to investigate the incidence of thyroid nodules and of thyroid cancer in a large group of children and adolescents (567) with HT followed-up for a m...

Background: Growth hormone (GH) treatment is indicated for children who are born small for gestational age (SGA) and fail to achieve sufficient catch-up growth during infancy and remain short throughout childhood.Aims: To evaluate the effect of GH treatment in a large, multicentric, Portuguese SGA children cohort and to analyze for correlation between GH treatment response and clinical factors.<str...
