Objective: Recent reports have suggested that air pollution may impact thyroid function, although the evidence is still scarce and inconclusive. In this study we evaluated the association of exposure to air pollutants to thyroid function parameters in a nationwide sample representative of the adult population of Spain.Methods: The [email protected] study is a national, cross-sectional, population-based survey which was conducted in 2008-2010 using a random clust...

Introduction: ACTH-secreting pituitary adenomas occasionally present as aggressive pituitary tumors (APT), with invasion of surrounding structures, rapid growth, resistance to conventional therapies and multiple recurrences. In rare cases they can progress to pituitary carcinomas (PC) in several years, diagnosis being made upon the documentation of systemic or central nervous system (CNS) metastatic spread. Among pituitary carcinomas, the most common malignant subtypes are lac...

Introduction: Acromegaly is a rare, challenging disease that if not appropriately treated can lead to numerous complications. Some of the most frequent complications are cardiovascular (hypertension, secondary cardiomyopathy, arrhythmias, valvulopathies, heart failure) and metabolic (secondary diabetes, various alterations of the lipid metabolisms). Aim: The aim is to asses the impact of long-term acromegaly on the cardiovascular system and glucide and l...

Background: Post surgery hypocalcemia is the most common sequel of thyroidectomy. An accurate prediction of hypocalcemia in the immediate postoperative period would enable the selection of patients for appropriate treatment and facilitate early discharge. Objective: This study aims to investigate the prevalence of hypocalcemia after thyroidectomy and to identify potential risk factors. Methods: This is a retrospective cohort study ...

Introduction: Pituitary adenomas are the most common pituitary tumours, but in 18% of cases we can find other rare tumours like: Rathke’s cleft cyst, craniopharingyomas, chordomas, meningiomas, infiltrative or infectious disease. Meningeal melanocytoma is a benign neoplasm of central nervous system, commonly located in the base of the brain, cerebellopontine angle and the pineal body, difficult to differentiate from a nonfunctional p...

Objectives: Distant metastases in MTC adversely affect disease prognosis. Somatic mutations in spMTC as well as Variant Allele Frequency (VAF) have been related to tumor burden, disease course and the response to TKIs. The aim of this study is to report three cases of nucleotide (nt) insertions/deletions (indels) in the RET oncogene in relation to disease course/response to TKIs.Methods: Of 195 spMTC patients followed-up in Dept. Clinical Therap...

Introduction and Aim: Obesity is associated with an increased risk of hypothyroidism and chronic autoimmune thyroiditis (AIT). However, little is known about the underlying pathogenic mechanisms. Recently it has been evaluated the role played by sex hormones in the onset of AIT and, analysing the data from a large cohort of normal/overweight males, a positive correlation between an increased ratio of estradiol/testosterone levels (E2/T) and AIT was found. Since obese males are...

Introduction: Thyrotropin receptor stimulating antibodies (TRAb) are responsible for Graves’ disease (GD) manifestations. Other thyroid antibodies, namely thyroperoxidase (TPOAb) and thyroglobulin (TGAb) antibodies are highly prevalent in GD, but their roles in GD presentation and evolution are controversial.Methods: We retrospectively analysed TPOAb and TGAb levels and evolution in 88 consecutive patients with newly diagnosed GD between 2000 and 20...

Background: Human cancer is characterized by the accumulation of somatic alterations including base substitutions, indels, structural rearrangements and somatic copy number alteration (CNA), either gain or loss, of chromosomes that can be responsible either for initiation and/or cancer progression. About 80% of Sporadic Medullary Thyroid Carcinoma (sMTC) harbor RET or RAS somatic alterations with a negative prognostic role for the presence of the RET mutation; a few s...
