Thiazolidinediones have demonstrated some efficacy in promoting radioiodine uptake of previously poorly radioiodine-responsive thyroid cancers. We describe the effect of rosiglitazone, in promoting uptake in thyroid metastatic tissue with weak uptake in order to treatment with radioiodine in two patients.Case 1: A 62-year-old woman with thyroid cancer and negative I-131 body scan post therapy (150 mCi) with presence of recurrent disease (PET positive in ...

Patients with persistent PHPT after parathyroidectomy (PTX) or contraindications for PTX often require chronic treatment for hypercalcemia, representing an unmet medical need. In an open-label, single-arm study in the US and EU, 17 patients underwent a variable length titration phase (maximum 16 weeks) with a maintenance phase (MP) of up to 3 years. Patients were eligible if they had (1) persistent PHPT following PTX or were considered contraindicated for PTX, and (2) serum ca...

Background: Nadir GH<2 mU/l in OGTT, normal IGF-I and mean GH<5 mU/l in the growth hormone day curve (GHDC) are considered the therapeutic endpoints in patients with acromegaly. However, discrepancies between these parameters have been reported.Aim: To compare the utility of the above tests in assessing the acromegaly status following surgical treatment.Patients and methods: Twenty-six consecutive patients (16 females) diag...

Introduction: Pituitary adenomas causing acromegaly are immunocytochemically divided into 3 main groups: growth hormone (GH) cell (A), those with GH and prolactin (PRL) cell differentiation (B) and plurihormonal (C). Recent large series comparing the hormonal and imaging features of these tumours at diagnosis are lacking.Objectives: To investigate differences in the presenting hormonal and imaging data associated with the above groups of adenomas.<p ...

Purpose: A combined model of clinical, biochemical and radiological variables could help to predict autonomous cortisol secretion (ACS) in adrenal incidentalomas (AI).Methods: We analyzed retrospectively 100 patients diagnosed of AI between 2011 and 2015. AI was defined as an adrenal mass>1 cm, accidentally discovered by radiologic examination. ACS was ruled out (ACS-) by serum cortisol post-dexamethasone suppression test (Nugent) <3 μg/dl, ...

Background: Polycystic ovary syndrome (PCOS) is a common endocrine condition in women at reproductive age, in whom, glucose metabolism disturbances are commonly observed. In addition, overweight and obesity, especially visceral obesity, are more prevalent in PCOS women, which enhances the resistance to insulin action, and as consequence, the onset of impaired glucose tolerance (IGT) and/or type 2 diabetes mellitus (T2DM). Clinical guidelines recommend oral glucose tolerance te...

Introduction and objectives: The strategies for therapy of metastatic medullary thyroid carcinoma (MTC) are limited. Although Tyrosine kinase inhibitors (TKI) seem to be the first-line treatment, we want to explore other possibilities. Metaiodobenzylguanidine (MIBG) is a guanethidine derivative, structurally similar to norepinephrine. It was developed as an imaging agent with 123I radiolabeling. MIBG localizes neuroendocrine tumors including MTC. We are investigatin...

Introduction: Tyrosine kinase inhibitors (TKIs) are used for treatment of iodine-refractory differentiated thyroid cancer (DTC) in patients with progressive advanced disease.Sorafenib and lenvatinib are the TKIs currently approved for this indication.Objective: To describe the clinical experience in patients with iodine-refractory DTC treated with TKIs in our Institution.Materials and methods: Restrospective cohort study of patient...

Introduction: There are known biological differences between men and women in coronary heart disease. It is important to know these differences in order to avoid inequalities in prevention, diagnosis and treatment of this pathology.Methods: We designed a retrospective, descriptive study in which we included all diabetic patients admitted to the hospital with acute coronary syndrome in 2016. Demographic data and degree of control of risk factors were regi...

Thyroid hormone (TH) signaling is essential for nervous system development. The clinical relevance of this simple statement is underscored by the severe neurological phenotypes resulting from global TH deficiency or perturbed local TH signaling during fetal development. A major aim of our research is to better understand the local action of TH during early human cortex development using cerebral organoids derived from human induced pluripotent stem cells (hiPSC) as a model sys...
