Background: The complex involvement of multiple metabolic defects in the pathogenesis of type 2 diabetes mellitus (T2DM) makes difficult the treatment in monotherapy, therefore, the use of different antidiabetic drugs with different and complementary mechanisms of action could result in better glycemic control with favorable metabolic changes.Objective: To determine the effectiveness and safety of the addition of a sodium-glucose co-transporter type 2 in...

Background: Cross-sex hormone therapy (CHT) is known to lead to alterations in cardiovascular risk factor(CVRF).Objective: To assess changes in lipid profile and other CVRF in transsexual subjects receiving CHT.Materials and methods: Retrospective longitudinal study. We evaluated individuals with gender identity disorder following CHT, assisted in the Gender Identity Unit from 2015 to 2017. Primary endpoint was lipid profile change...

Introduction: The aim of our study was to evaluate the causes of thyrotoxicosis detected during pregnancy as well as to determine the prevalence of thyroid nodular disease (TND) in our population and which factors are associated with this condition.Methods: We performed a retrospective review of 1,760 patients between April 2014 and September 2017 remitted from the gynecology department due to thyroid dysfunction detected in the 9th week of pr...

Objetive: The aim of our study is to asses the validity of ultrasound patterns proposed by the ATA and malignancy risk in the cytological diagnosis classified by the Bethesda System.Methods: Prospective study including all thyroid nodules (with no previous cytological results), assessed in our center from July/2016 to June/2017. We classified nodules in ATA sonographic risk patterns and follow-up its fine needle aspiration (FNA) recommendations. The stat...

Introduction: Ectopic thyroid tissue is a rare embryonic developmental defect that occurs during the thyroid transition from its initial position in the floor of the primitive bowel to a pre-tracheal location. This defect has a prevalence in the general population of 0.3–1/100,000 inhabitants, increasing to 0.5–1/4,000 patients with thyroid pathology. It is more common in women and can be diagnosed at any age, with diagnosis being more common in young individuals.</p...

Introduction: Ophthalmopathy and dermatopathy are the most frequent manifestations of Graves Disease (GD). It is also known the relation between GD and other autoimmune diseases like myasthenia gravis. Thymus hyperplasia in GD is already documented on literature but it’s mechanism is not well understood. There are two possible explanations, one related to thyrotrophin receptors stimulation present on thymus, and other related to tissue stimulation due to generalized hyper...

Somatostatin (sst) receptors are expressed in many tissues and multiple subtypes are often present in the same cells. Their activation by endogenous sst as well as by sst-analogues leads to inhibition of secretion and growth in some tumor, such as the neuroedocrine ones.Pheochromocytomas (Pheos) and paragangliomas (PGLs) are neural crest-derived tumors which can be sympathetic or parasympathetic in origin and present themselves as sporadic or familial. T...

Organ-specific autoantibodies have been detected in patients with autoimmune diseases. The relationship between pituitary autoantibodies and lymphocitic hypophysitis has not yet been established and it is not clear if they are a specific serological marker of the disease.The aim of the present study was to evaluate the prevalence of pituitary autoantibodies in patients affected by autoimmune and nodular thyroid disorders.803 patien...

Hypothalamic neuropeptide PACAP is a potent endogenous stimulator of adenylate cyclase synthesis in gonadotrope cells. Previously we found that, in contrast to GnRH, also Cu–GnRH complex is able to induce cAMP/PKA pathway activity.The aim of the study was to determine whether Cu–GnRH can act via GnRH-R and/or PAC-1 receptors to stimulate cAMP/PKA intracellular signaling. Moreover, we compared PACAP and Cu–GnRH ability to activate cGMP/PKG ...

Introduction: Non-alcoholic steatohepatitis (NASH) is part of the spectrum of non-alcoholic fatty liver disease (NAFLD). NASH commonly occurs in patients with type 2 DM and is less recognised in type 1 DM. The natural history of NASH in adult patients suggests potential development of progressive fibrosis and cirrhosis. However, secondary glycogenosis, commonly occurs in type 1 DM, is reversible when good glycaemic control is achieved, but may be misidentified as NASH b...
