Introduction and objectives: Transsexuality refers to discrepancy between the assigned sex/gender at birth and the one that the subject identifies with. The use of the cross hormone treatment as sex/gender change method implies the necessity of monitorize the hormone levels and potential treatment risks. Our study tries to evaluate the relationship between the hormone changes and the changes in the cardiovascular risk factors and the bone mineral density.<p class="abstext"...

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...

Inroduction: Polydipsia -excessive oral intake of liquids, with/without thirst- can induce euvolemic hyponatremia. Adequate inhibition of AVP secretion induced by low plasma osmolality (POsm) is reflected in a urinary osmolality (UOsm) ≤100 mOsm/kg. However, increased fluid intake can also reveal underlying non-osmotic AVP secretion, induced by pain, nausea, and/or SIADH, with UOsm >100. Iatrogenic polydipsia is characterized by increased liquid intake without thirst...

Introduction: Adrenocortical carcinoma (ACC) is a rare and aggressive tumor that accounts for 0.2% of cancer-related deaths. Case series and prospective studies are very limited due to its low prevalence. Current knowledge is based primarily on the opinions of experts in specialized units. The aim of this study is to perform a descriptive analysis of the management and prognosis of patients with ACC in HCSC in the last 20 years.Material and methods: Eigh...

Introduction: Post-surgical hypoparathyroidism (PSHP) is a frequent complication following ENT surgery. Some patients with head/neck cancers require enteral nutrition (EN) due to dysphagia, mucositis after radiotherapy or chemotherapy, or post-surgical anatomical complications. Formulas of calcitriol are not suitable to be administered via enteral feeding tubes, and side effects of systemic antineoplastic treatment (nausea, vomiting) make calcium and phosphate serum levels dif...

Introduction: Guidelines suggest that serum basal (nonstimulated) thyroblobulin (bTg) with sensitive assays (Functional Sensitivity-FS- below 0.1 or 0.2 ng/ml) could substitute the measurement of serum Tg levels after TSH stimulation during the follow-up of patients with differentiated thyroid cancer (DTC) when basal results fall below the FS.Objective: A sensitive assay for Tg was incorporate in our center (Chemiluminiscent Tg Access; Beckam Coulter; Br...

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. Endoscopically, they are usually smaller than 1 cm and often multiple. These tumors usually present a non-aggressive evolution. Our goal is to approach the presence of risk fac...

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: Endocrine Society guideline indications for screening (EGS) of hypertensive patients for hyperaldosteronism are not universally followed in clinical Endocrinology. We present a series of patients with hyperaldosteronism, diagnosed following strict EGS compliance.Methods: Retrospective. Following compliance with EGS in all patients attended in a general Endocrinology outpatient clinic, 70 hypertensive patients were diagnosed with hyperaldost...

Introduction: Tolvaptan is the only V2-receptor antagonist authorized for use in Europe in patients with SIADH. Its initiation requires hospitalization. Our goal was to analyze the safety and efficacy of tolvaptan started in a Hospital Day-Ward.Material and methods: Retrospective descriptive study of 33 ambulatory patients with mild/moderate SIADH-induced chronic sustained hyponatremia initiating tolvaptan therapy in the Day-Ward of a tertiary center ove...
