Introduction: Cutaneous metastization of differentiated thyroid carcinomas is a rare event.Clinical case: MMS, a 69-year-old male was submitted to left hemithyroidectomy+isthmectomy on May 2006 after FNA of a left node revealed follicular tumor. Histology showed Hurthle cell adenoma. The patient maintained irregular follow-up by endocrinologist. In October 2011 he referred the appearance of small bilateral cervical skin nodules. Physical exam showed thre...

Objective: To evaluate possible differences in 24 hours blood pressure (BP) and vascular risk profile (VRP) of normotensive (NT) and untreated hypertensive (UHT) patients with normoglycemia (NG) or Impaired Fasting Glucose (IFG).Design and methods: From 9.812 nondiabetic subjects taken from the Spanish ABPM (Ambulatory Blood Pressure Monitoring) Registry, we compared 24-h BP and VRP differences between patients with NG [n-6,875 (43.3% NT and 56....

In the last years estrogens have emerged as important regulators in male reproductive function. Spermatogenesis depends on the tight control of germ cell apoptosis and several studies indicated estrogens as playing a role in this process. The stem cell factor (SCF), a membrane-bound cytokine, and its receptor (c-kit), and the Fas ligand (FasL)/Fas receptor (FasR) system are powerful mechanisms controlling germ cell proliferation and apoptosis through the direct membrane commun...

Epidemiological studies have shown that plasma SHBG levels correlate with plasma adiponectin levels, both in men and women. To the best of our knowledge there are no reports describing any molecular mechanism by which adiponectin regulates hepatic SHBG production. The aim of the present study is to explore whether adiponectin regulates SHBG production by increasing HNF-4α levels through reducing hepatic lipid content. For this purpose, in vitro studies using huma...

Introduction: Several studies point towards lower testosterone levels (TL) in patients with obesity and/or insulin resistance (IR).Aim: To analyze the influence of anthropometric parameters and IR on TL in obese men and weight-dependent changes after a short-term weight loss program.Methods: Data were collected from a group of male patients, aged 18 to 65, when they attended a first obesity appointment and at reassessment 6 months ...

Context: Acromegaly associated to schizophrenia was firstly reported ~60 years ago and, so far it is unclear whether this association is causal or not.Objective: We report on three new cases and discuss the potential pathophysiological mechanisms of this association.Results: We report two males and one female diagnosed with schizophrenia and treated for several years with antipsychotics who developed acromegaly due to a GH-secretin...

Aim: To evaluate the serum levels of resistin and adiponectin, and the potential relationship between these adipokines, thyroid function, lipid profile, C-reactive protein (CRP) and homocysteine levels in patients with autoimmune thyroiditis (AIT) and subclinical hypothyroidism (SCH).Methods: patients with AIT (58 females; 47.7±16.7 years) were studied; 33 of them had also SCH. These patients were diagnosed by a positive result in an anti-peroxidase...

Background and objectives: The finding of a thyroid nodule is a very common occurrence in clinical practice. Management of thyroid nodules requires a multidisciplinary approach that may be eased by a high-resolution thyroid nodule clinic. We report our clinical experience and outcomes in a high-resolution thyroid nodule clinic.Materials and methods: We conducted a retrospective analysis of 1674 thyroid nodules evaluated in a high-resolution clinic from a...

Background: Short Synacthen test (SST) is being increasingly used in various clinical conditions, mainly for completion purpose of ruling out adrenocortical insufficiency rather than actively suspecting it (for instance hypothyroidism with tiredness, type 1 diabetes with hypoglycaemia). The aim of our retrospective analysis was to assess if a random cortisol could predict the outcome of SST.Method: Data were collected on all SST done at the endocrine uni...

Proton pump inhibitors (PPI) are widely prescribed. PPI-induced diarrhoea and hypomagnesaemia are well-documented in literature. Hypomagnesaemia is well-known to cause functional hypoparathyroidism. We describe a patient who had transient profound hypoparathyroidism which improved on discontinuing PPI and normalising severe hypomagnesaemia.A 72-year-old male, who was on oral anti-diabetic medications, calcium/vitamin D3 supplements and PPI, presented wit...
