Introduction: Non-functioning pituitary adenomas (NFPAs) represent the most common pituitary tumour. They usually appear in the middle age of life, without differences between genders. Mass growth produces the first symptoms so the diagnosis is usually late. Surgery is the first-line treatment with variable success (19-83%). The objective of this study is to evaluate the symptoms, diagnosis, treatment and final state of patients with NFPAs.Methods: Obser...

Introduction: The association of acromegaly and polyostotic fibrous dysplasia is a rare entity that presents more difficulties in achieving an effective treatment than classical acromegaly. Pregnancy is infrequent and carries a high risk when acromegaly is active.Clínical case: A 27 year old woman surgically treated for facial asymmetry, without café-au-lait spots or precocious puberty, was evaluated in 1992 after a normal pregnancy. In the bio...

Background: The short-term follow-up of patients with differentiated thyroid cancer (DTC) after the initial treatment is based on the measurement of stimulated thyroglobulin (s-Tg) and the use of diagnostic whole body scan (WBS).Objective: To evaluate the clinical utility of WBS performed at 6–12 months after thyroidectomy. Examine the correlation between s-Tg and results of WBS.Methods: We retrospectively evaluated all patien...

Introduction: Due to the widespread use of imaging studies performed in hospitalised patients for other indications, adrenal incidentalomas (AI) are frequent findings in the everyday clinical practice. The objective of this research is to describe the prevalence of hormonally active and malignant AI.Patients and methods: Observational retrospective study of a cohort of patients who consulted in the Endocrinology service between 2005 and 2015 because of a...

Introduction: Incidental focal uptake in the thyroid gland is detected in 1%–2% of 18FDG-PET examinations. FNA is recommended due to an increased risk of malignancy (25–50%), but these figures are extracted from the studied cases (about a half). Moreover there is controversy about the maximum standardized uptake value (Suvmax) ability to discriminate between benign or malignant nodules.Methods: We retrospectively reviewed 4207 FDG-PE...

Introduction: The Bethesda System classifies suspicious thyroid nodules or those with a large size after fine-needle aspiration (FNA) depending on the risk of malignancy through its cytology study. Bethesda category 3 (B3) implies atypia of uncertain significance or follicular lesion of undetermined significance. Objectives: To determine the final diagnosis of category B3 nodules and the number of cases in which a second or third FNA results in a conclusive category (B2, B4, B...

Background: The management of patients with differentiated thyroid cancer (DTC) has been changing in recent years and aggressiveness of treatment depends on the risk of persistent or recurrent disease.Objective: The aim of this study was to assess the efficacy of low doses of Radioactive Iodine (RAI;131I) therapy in patients with DTC.Methods: We retrospectively evaluated all patients who were diagnosed with DTC (n</e...

Prevalence of hyperandrogenism (HA) and polycystic ovary syndrome (PCOS) in female to male transsexuals (FMT) is controversial. To known the prevalence of hyperandrogenism and PCOS in FMT, and their relation with insulin resistance (IR) and other cardiovascular risk factors (CVRF), we studied 77 Spanish consecutive FMT cases, the first ones who appeared in our Gender Unit between May 2007 and Dec 2008, aged 18–43 years. The subjects had never received hormonal treatment o...

The somatostatin analogue pasireotide is approved for the treatment of Cushing’s disease, where it achieves biochemical normalization in ~40% of patients. Predicting pasireotide resistance would help avoid unnecessary treatment. Pasireotide mediates its antisecretory action by binding to somatostatin receptor 5 (SSTR5). Almost half of corticotroph tumours carry mutations in the ubiquitin specific protease 8 (USP8) gene that encodes for a deubiquitinase. Pre...

Introduction: Severe hypoglycemia and retinopathy are two of the main complications of diabetes mellitus (DM). Traditionally, glycosylated hemoglobin (or A1C) has been used as the gold standard measurement of glycemic control; however, there is a significant percentage of complications riskassociated with the evolution of diabetes that is not fully explained by this single marker. Short and long-term glycemic variability has been postulated as one of the main variables that co...
