Background: T1DM incidence in children varies across regions and countries, showing a continue rise Worldwide.Objective and hypotheses: To determine the incidence of T1D in Chilean children under 20 years between 2006 and 2012.Method: We reviewed mandatory notifications of T1D (GES Program) in Chile’s public health system in population younger than 20 years between 2006 and 2014. Data were obtained from the Department of Infor...

Background: Hyperinsulinemic hypoglycemia (HH) is the most common cause of severe, persistent neonatal hypoglycemia. Treatment of diffuse forms that is unresponsive to diazoxide and octreotide is near total pancreatectomy.Objective: To describe the clinical characterization of a newborn with congenital HH due to a diffuse pancreas lesion and unresponsive to diaxoside.Case report: Preterm term male of 33 weeks born to non-consanguin...

Background: Kenny-Caffey syndrome type 1 is a rare autosomal recessive syndrome caused by mutation in the TBCE gene (Tubulin specific chaperone E) located in the chromosome region 1q42-q43. Less than 60 cases have been reported in the literature especially in the Middle East and Arabic countries. This syndrome is characterized by growth retardation, dysmorphic features, with thickened bone cortex and medullary stenosis, hypoparathyroidism, teeth anomalies. Hypopituitarism with...

Background: Spermatogonia contain processing bodies (P-bodies) that harbour P-element induced wimpy testis (Piwi) proteins associated specifically with Piwi-interacting RNAs to silence transposable DNA elements. In mice loss-of-function mutations in the Piwi pathway lead to de-repression of transposable elements, resulting in male-specific sterility.Objective and hypotheses: No previous studies have examined expression of transposons silencing gene micro...

Background: A second screening for congenital hypothyroidism between the 2nd and the 4th weeks of life in preterm infants is recommended in order to avoid false negative on the first screening. The incidence of transient hypothyroidism in this population is high.Objective and hypotheses: i) Analyse the utility of the second screening in our population of preterm infants. ii) Follow-up of those preterm infants with hypothyroidism.Me...

Background: Turner syndrome (TS) involves a partial or complete loss of an X chromosome. TS patients have an increased susceptibility to various disorders.Objective and hypotheses: To describe the clinical presentation, genotype and follow-up of TS patients controlled in the Pediatric endocrinology department of our hospital.Method: Retrospective study of patients diagnosed with TS at the ‘Navarra Hospital’ between 1980&#...

Background: The central melanocortin system is highly involved in the control of energy metabolism, receiving and integrating numerous metabolic signals, such as leptin, and biallelic mutations in several genes of the pathway have been reported in severe obesity. However, whether and how heterozygous rare sequence variants (hetRSVs) in genes of this satiety pathway contribute to the development of obesity is poorly explored.Objec...

Objective: To study the impact of dual therapy on BMD and Inhibin B in a group of transsexual male adolescents who initiate treatment with advanced pubertal development.Patients and methodology: Retrospective study of 16 male minors who initiated treatment (Triptorelin and later Testosterone) with complete pubertal development. Variables included: age, weight and height at baseline and at the last visit (calculated in SDS for assigned age and sex), BMD i...

Introduction: Primary hyperparathyroidism (PHPT), often caused by a single adenoma (80%–85%) or hyperplasia or adenomas involving multiple glands, is the major cause of hypercalcemia. PHPT is common and occurs in individuals of all ages, but its prevalence is lower in young adults. Parathyroid tumors and PHPT can be caused by germline (hereditary PHPT) or somatic mutations of tumor suppressor genes (e.g., multiple endocrine neoplasia type 1 and CDC73) and...

Introduction: Turner syndrome (TS) is a genetic condition with different phenotypic expressions depending on karyotype. Due to genetic prenatal testing, its prevalence is getting lower. The objective was to analyze the presence of different comorbidities associated with TS according to the karyotype and evaluate if there is follow-up in adulthood.Methods: Descriptive retrospective study including all the patients genetic...
