Introduction: Hyponatremia is the most frequent electrolyte disorder in hospitalised patients. Our aim was to determine the incidence, mean hospital stay, readmission rate and mortality rate among patients with acute heart failure (HF) and hyponatremia.Methods: Retrospective analysis of data collected from the minimum data set (MDS) of Spanish National health System during 2005–2012 from discharged patients of Internal Medicine with HF and hyponatre...

Introduction: Primary hyperparathyroidism (PHP) has been postulated to be a cause of primary hyperaldosteronism (PHA). In fact, PTH receptors have been detected in aldosteronoma tissue. Hyperaldosteronism can also induce elevation of PTH levels, as increased circulating volume increases calciuria, with secondary elevation of PTH levels as serum calcium levels rise. We studied the prevalence of PHP in a group of patients diagnosed with PHA either following or simultaneously wit...

Introduction: Type 1 Gastric neuroendocrine tumors account for 70 to 80 percent of all gastric neuroendocrine tumors (G-NETs) and they are found more commonly in older adults, particularly women. They are associated with autoimmune metaplastic atrophic gastritis (AMAG) with or without pernicious anemia. They are usually smaller than 1 cm and often multiple. Our goal is to describe different characteristics of type 1 G-NETs and to study possible prognostic factors related to th...

Introduction: Hypothyroidism (hT) is a very common disease that can affect inpatients prognosis. We analysed the clinical profile of patients with hT admitted to Internal Medicine using a large clinical-administrative database.Methods: A descriptive analysis based on the minimum-data-set database of the Spanish National health System of patients who were discharged from the services of Internal Medicine with the diagnoses of hT during 2005–2012 was ...

Introduction: Furosemide can be used in the treatment of SIADH. However, to be effective, renal medulla osmolality (OsmRM) as reflected in urinary osmolality (UOSM) must be high. Sodium is the most important contributor to OsmRM, which increases following the administration of oral salt. We analyze the use of an oral salt load followed by furosemide for the acute/short-term treatment of euvolemic SIADH hyponatremia.Method...

Introduction: Control of hypertension (HT) is essential to reduce cardiovascular events in diabetic patients (DPts). However, studies indicate that only 50% of DPts with treated hypertension present adequate blood pressure (BP) control. Yet Endocrine-Society-Guideline (ESG) screening for primary hyperaldosteronism (PHA) is rarely applied. Furthermore, in patients with essential hypertension (EH), longer-acting hypertension medication (HM) improves 24-hour BP when compared to r...

Introduction: MTC accounts for 5% of thyroid cancers and can occur sporadically or as part of the multiple endocrine neoplasia type 2 syndrome (MEN 2). The objective of our study is to evaluate the prognostic factors and outcomes of patients with MTC in the community setting.Methods: Retrospective descriptive multicenter study of patients with histological diagnosis of MTC. Descriptive, bivariate analyses (Student t for cuantitative and ...

Introduction: Clinical trials indicate that Tolvaptan is safe and effective in the treatment of patients with sustained mild/moderate SIADH-induced euvolemic hyponatremia. Tolvaptan doses are often modified during chronic use. We present the weekly doses of a series of patients on chronic therapy, followed up in outpatient clinic.Methods: Retrospective, cross-sectional. 114 patients receiving tolvaptan for chronic SIADH were followed up in a Hyponatremia...

Introduction: In the treatment of amiodarone-induced type I or mixed thyrotoxicosis, sodium or potassium perchlorate is often associated to thionamides, when the latter are insufficient for a prompt control of thyroid hormone secretion. Perchlorate competes with iodine for entrance into the follicular cell, and also induces a discharge of iodine from these cells with each administration. We compare the effect of 3 different regimes of perchlorate with methimazole on control of...
