Introduction: Type 1 diabetes (T1D) is a chronic autoimmune disease characterized by the presence of pancreatic-autoantibodies, which are diagnostic biomarkers. The detection of autoantibodies in first-degree relatives of patients with T1D is considered a risk factor for developing the disease; however, there is little information on how long it takes from the detection of autoimmunity to the clinical onset of T1D.Objectives:</st...

Objective: Despite published guidelines, there is no single approach to management in congenital adrenal hyperplasia (CAH). The objective of the study was to explore the variations in treatment for CAH in Spain.Material and methods: A retrospective study in a single center was done analyzing the data provided by patients and relatives through the Spanish Association of CAH from a online survey of 25 questions. It was dif...

Background: GH deficiency may not persist into adulthood. Thus, it is recommended to reassess it after reaching adult height. However, according to stimulation tests, they have poor specificity, reproducibility, and poor standardization of hormonal measurement, and they are expensive and involve risks.Objective and hypotheses: Establish if IGF1 would be a better reassessing method than stimulation tests in adult GH defic...

Adamantinomatous craniopharyngiomas (ACPs) are clinically challenging tumours, the majority of which have activating mutations in CTNNB1. They are histologically complex, showing solid tumor component comprised of different morphological cell types (e.g. β-catenin accumulating cluster cells and palisading epithelium), surrounded by a florid glial reaction with immune cells, but also a cystic component. ACP cysts often exert substantial mass effect on critical str...

Introduction: Steroidogenic factor-1 (SF1), encoded by the NR5A1 gene, regulates several genes involved in male sexual determination, such as SOX9 and AMH, cholesterol mobilization and synthesis of a number of steroidogenic enzymes, like 3βHSD, and androgen biosynthesis, like INSL3. Mutations in NR5A1 have been associated to a broad phenotypic spectrum in 46, XY subjects, including pure gonadal dysgenesis, infertility, anorchia...

Background: The primary goal of treatment is to achieve a final height within the normal range and avoid the physical and psychological consequences of short stature (SS). If after a time, treatment efficacy criteria are not achieved, it is necessary to revalue its usefulness. There is no consensus about which conduct should be adopted in these cases. An alternative, is the suspension of rhGH treatment and evaluate the clinical and biochemical results to decide to continue or ...

Background: Children with more than one AID (pediatric polyautoimmunity) may have a stronger genetic component than children with a single AID. PTPN22 C1858T SNP has been associated with multiple different AIDs in adults and children.Objective and hypotheses: Evaluate the association of PTPN22 C1858T gene polymorphism with pediatric polyautoimmunity.Method: A cross-sectional study was performed in subjects with an AID of p...

Background: Recognizing the risk of developing obesity is essential to implement preventive measures to avoid the increasing prevalence of obesity in adulthood.Objective: To evaluate predictive factors that may be associated with overweight and obesity in early adulthood.Method: A regression analysis of different variables of body composition in a normal population have been done. The sample consisted of 122 boys and 120 girls foll...

Background: Treatment with GH of children born SGA allows an increase in growth velocity (GV) and improves adult height. Increased insulin resistance has been described in these patients, which reverts after interrupting GH administration. However, long-term metabolic consequences are not clearly established.Objective and hypotheses: Describe insulin resistance (HOMA-IR index) and auxological development (GV and height) in SGA children treated with GH fo...

Introduction: It is thought that sex hormone binding protein (SHBG) is involved in glucose homeostasis in addition to regulate the levels of sex hormones. Clinical studies associate reduced SHBG concentrations with insulin resistance (IR).Objective: To evaluate the relationship of SHBG with IR and hyperandrogenism markers in a group of adolescents affected with polycystic ovarian syndrome (PCOS), and how weight could affect these markers.<p class="ab...
