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, ...

The skeletal muscle expresses the Glucagon-like Peptide 1 (GLP-1) receptor, although its effects in this tissue are not well known. Muscles are a major sink of energy substrates. The aim of our study was to examine the mid-term effect of Liraglutide (LIRA), a GLP-1 receptor agonist, in the expression of molecular indicators of the metabolic activity of the muscle, which includes enzymes, transporters, and intracellular signals. Twenty young Spague-Dawley male rats (350-400 g) ...

Background: We previously showed that menopausal hormone therapy (MHT) favorably affects both bone density and microarchitecture with persistent benefit after its withdrawal (1). Looking for indirect factors contributing to bone effects, we investigated the relation between MHT and changes on fat and lean (muscular) tissue. Existing results on MHT and body composition are conflicting and large cohort studies are lacking.Material and methods: The OsteoLau...

Introduction: The use of immunotherapy in oncology patients is increasing and is likely to continue to increase in the future. It is widely known that therapies have endocrinological side effects which can be serious, but maybe are also useful indicators to judge a response to the treatment. Presently, we do have not enough information regarding these side effects and their evolution.Materials and methods: Observational and retrospective study of 162 onc...

Introduction: Hypothyroidism in pregnancy is a topic widely studied in recent years, especially in those women with positive autoimmunity. However, usually the only determination of antibodies that is made is the thyroid antiperoxidase antibodies (anti-TPO). In this study we wanted to know what incidence of anti-thyroglobulin antibodies (anti-Tg) our pregnant women present and what repercussion they can have on thyroid function.Materials and methods: Ant...

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, material and methods: Differentiated thyroid cancer is a pretty common reason for consulting in our specialty. In general terms, the prognosis is good in the main histological type but there are many others that can worsen the prognosis. It can determine the kind of surgery from hemithyroidectomy (e.g. microcarcinoma) to no intervention because of its extension at the moment of diagnosis. We have collected the data of our patients with differentiated thyroid canc...

Introduction, material and methods: Papillary thyroid cancer is well known to be a tumour with a good prognosis; in spite of that, it usually presents many recurrences that increases its morbidity. Follicular thyroid cancer is less frequent but has a higher rate of hematogenous dissemination and higher mortality than papillary thyroid cancer. We have collected the data of our patients with differentiated thyroid cancer during the period from 2000 to 2015. In this study, we hav...

Introduction: Vitamin D deficiency is very common in our population.It is not clear which is the most effective vitamin D dosing regimen in patients with deficiency.Objective: To compare two vitamin D supplementation regimen in patients with vitamin D deficiency.Material and methods: This is an interventional study: Patients atended in our clinic during May and June 2017 with 25-Hydroxyvitamin D below 30 ng/ml were consecutively se...

This is a 38-year-old male, a regular user of a gym with the sole purpose of improving his physical performance and muscular strength and habitual consumer of hyperproteic dietary supplements. Among his PAs he denies toxic habits, and highlights the removal of the right testicle in childhood. Consultation for decreased desire and sexual potency, together with pain and turgor in the left breast; hair loss at the frontal level, in analytic carried out by the Primary Care Physici...
