The pituitary is an anatomically well protected endocrine gland in permanent contact with the central nervous system. Although it was known that pituitary has plasticity in response to the physiological demands of the body, there were few clear data about the post-natal mechanisms in charge of this plasticity. The discovery of a group of cells expressing stem cell markers precisely organized in the outer zone of the adenopituitary open up new possibilities to explain the const...

Objective: To compare the effects of a classic therapy to those of a novel treatment for androgen excess in adolescent girls.Study design: Randomized, open-labeled trial over 12 months.Study participants: Adolescents (n=34; mean age 16 year, BMI 23 kg/m2) with hyperinsulinemic androgen excess and without risk of pregnancy.Interventions: Ethinyl estradiol-cyproterone acetate (EE-CA; Diane 35 ...

Objective: Modifications in lifestyle and diet are major contributors for the high prevalence of obesity. Very few longitudinal studies have evaluated the changes in body weight over time. Dynamic changes in body weight are also an important indicator of risk for type 2 diabetes. The aim of this study is to assess factors associated with weight gain in a population of Spanish adults.Methods: The study was undertaken in two population-based cohorts of Spa...

Most kindreds of familial isolated pituitary adenomas (FIPA) with mutated AIP develop somatotropinomas, characterized by an aggressive clinical phenotype including early age at diagnosis, large tumours and frequent invasiveness. In non-family cases, the prevalence of AIP mutations in pituitary adenomas is lower than 10%. There is no information of AIP prevalence in isolated somatotropinomas characterized by poor response to conventional treatment.Aim: To...
