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: The multidisciplinary approach of the patients with GEP-NETs is very important, having a fundamental role the participation of the endocrinologist.Methods: Description of cases of GEP-NETs followed in the Service of Endocrinology of the SCCH from 1990 to 2016.Results: 95 patients were included, 53.7% were males, age 61.2 years (IR: 50.5–73.5). The diagnosis was incidental in 53.8%. 27.6% presented clinical secret...

Introduction: Neuroendocrine tumors (NETs) constitute a very heterogeneous group of rare neoplasms, although their incidence has increased in recent years. We describe its evolution and survival.Methods: Retrospective study. All patients with histopathological diagnosis of GEP-NETs performed at the HCSC between 2000 and 2016 were selected, data from the medical history were included. Statistical analysis were done with SPSS.Results...

Introduction: Hypoaldosteronism is characterized by the development of hyperkalemia, but can also induce hypovolemic hyponatremia. Trimethroprim can cause hypoaldosteronism through mineralocorticoid resistance. That hypoaldosteronism can induce hyponatremia in absence of Addison’s disease has been questioned. We studied the electrolyte disturbances found following initiation of trimetroprim therapy.Material and methods: Retrospective, analytical. La...

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: Primary hyperaldosteronism (PH) is characterized by autonomous adrenal aldosterone (A) hypersecretion. Unilateral adrenalectomy is the treatment of choice, when adrenal vein sampling (AVS) indicates lateralization of A secretion. To assure that each adrenal vein (AV) has been correctly sampled, cortisol levels in each adrenal vein must be higher than in the inferior vena cava. The adrenal gland cortisol/vena cava cortisol ratio is referred to as the selectivity i...

Introduction: Bariatric surgery (BS) has emerged as the most effective treatment for severe obesity, but weight regain after surgery is an important issue. The aim of this study was to evaluate the impact of different surgical techniques on long-term dynamic weight loss pattern.Materials and methods: We retrospectively included 444 patients with BMI > 35 kg/m2 who underwent different BS techniques: Sleeve gastrectomy (SG; n: 80), ...

Background: Branchial cleft cysts account for almost 20 percent of pediatric neck masses. They are usually present in late childhood or early adulthood, when a previously unrecognized cyst becomes infected. First branchial cleft cysts typically appear on the face near the auricle. Second branchial cleft cysts are the most common and they are usually located just inferior to the angle of the mandible and anterior to the sternocleidomastoid muscle. Third branchial cleft cysts ar...
