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: 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...

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: 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...
