Background: The pituitary set-point for TSH synthesis and secretion is known to be an individual parameter with a strong genetic influence. Type II iodothyronine deiodinase is a pituitary enzyme involved in local deiodination of T4 and negative feed-back loop for TSH secretion. Defects in DIO2 have not been reported in humans; however, Dio2 knockout mouse has pituitary resistance to T4 with elevated TSH, T4 and TSH/T4 ratio, with nor...

Background: Iodotyrosine deiodinase (DEHAL1) is a thyroidal enzyme that deiodinates mono- and diiodtyrosines (MIT, DIT) and recycles iodine, essential for synthesis of thyroid hormone. Iodotyrosine deiodinase deficiency leads to hypothyroidism, goiter and variable mental retardation. The age for clinical onset was reportedly very diverse, allegedly related to individual iodine nutrition.Clinical case: We report on a boy, offspring of consanguineous paren...

The incidence of TIDM varies greatly between different countries and regions. In Navarre, located in the north of Spain, at the western end of the Pyrenees, there has been a clear increase in the incidence of TIDM, from 13,5 cases per 100000 in the decade 1990-2000 to 20,1 cases per 100000 between 2006-2011. We wonder if this upward trend has continued in recent years. Our hospital is a reference center for Pediatric Endocrinology in Navarre.Obje...

The new techniques of molecular genetics are revolutionizing our clinical practice. This causes benefits in the diagnosis and prediction of diseases in patients, but also raises new ethical concerns that must be addressed. One of them is the susceptibility to cancer due to genetic risk. Children can be especially vulnerable in this area, as they do not freely decide the way forward. Regarding thyroid cancer, it is important to know which genetic syndromes are susceptible to ca...

Introduction: The Wilms tumor suppressor gene 1 (WT1) plays an essential role in urogenital and kidney development. Heterozygous germline mutations in WT1 have been classically associated with Denys–Drash (DDS) and Frasier syndrome (FS). Exonic missense mutations in the zinc-finger region are the cause of DDS and mutations affecting the canonic donor KTS splice site of intron 9 are the cause of FS. New phenotypes, as 46,XX testicular DSD...

Introduction: The incorporation of the interstitial glucose monitoring system, in the offer of services in the Andalusian Public Health System (APHS), means an opportunity for the implementation of a model of integration, and follow-up of glucose data, and the evaluation of their impact in health results.Purpose (Aim): The design and implantation of a model that allows the identification, registration of clinical data, i...

Background: Hypothalamic obesity (HyOb) is a disease characterized by weight gain resistant to lifestyle changes and dietary restriction. The main clinical findings are hyperfagia and decline of satiety, high levels of insulin and an increase of adipogenesis. The major problem for these patients is that conventional treatments, either medical or surgical are not succesful and have variable results.Objective and hypotheses: We aim to describe the natural ...

Case Report: A preterm boy was born at 35 weeks gestational age by cesarean section due to fetal macrossomia and polyhydramnios, weight 4980g (4.3 SDS, Intergrowth 21st), length 53cm (3.1 SDS), 1-min-Apgar 2. He needed resuscitation after birth, and his glycemia was 20 mg/dL. At the Neonatal Intensive Care Unit (NICU), he presented with severe hypoglycemia (10mg/dL) and required intravenous glucose infusion rate (GIR) 10mg/kg/min that increased progressively u...

Introduction: Generally, patients with X-linked hypophosphatemic rickets (XLH) experience normal puberty. However, they can be affected by metabolic and environmental factors that may predispose them to central precocious puberty (CPP) and impair their predicted final height, similar to the general population.Case Report: A female patient was diagnosed with XLH at three and received regular treatment with calcitriol and ...

Cushing’s disease (CD) is rare entity especially in pediatric patients. It is associated with significant morbidity. Early diagnosis and treatment is important for optimal outcome.Aim: To evaluate the clinical, biochemical, pathology, treatments and outcome in a cohort of CD pediatrics patients in a single tertiary center.Subjects and Methods: Retrospective review of 27 medical records of CD ...
