Introduction: Approximately 0.5% of the world population experiences gender dysphoria, a discrepancy between one’s biological sex and gender identity. Transgender men (TM), individuals who were assigned female at birth but who identify as men, can benefit from therapy with testosterone (T) to address gender dysphoria. Although unfavourable changes in lipid profiles have been previously reported, most studies did not show an adverse impact of testosterone treatment on fast...

Introduction: Percutaneous ablation has been used over the years for the minimally invasive treatment of liver, kidney, thyroid and, although less frequent, adrenal cysts. We describe the case of a young patient with a large adrenal cyst treated with ethanol ablation, avoiding adrenalectomy.Clinical case: We present a 32-year-old woman who is referred to Endocrinology due to a 10 cm adrenal incidental finding in an MRI performed due to disc herniation. A...

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...

Background: Co secreting Thyrotropin/growth hormone pituitary adenomas are rare, and their clinical presentation and long term management may be challenging. Clinically, the majority of plurihormonal pituitary adenomas are silent and diagnosis almost always relies on immunohistochemical analysis of the tumor tissue. Early detection is key to optimize patient mamagement. We report a case of pituitary plurihormonal macroadenoma with overt clinical hyperthyroidism and minimal GH ...

Introduction: Nelson´s Syndrome is defined as the presence of an enlarging pituitary tumor associated with elevated fasting plasma ACTH levels and hyperpigmentation in patients submitted to bilateral adrenalectomy for the treatment of Cushing´s disease. Case Report: We present a case of a 48 y/o woman who in 2015, was diagnosed of Cushing’s disease and underwent transsphenoidal adenomectomy but remission was not achieved, so the patient wa...

Introduction: Neutropenia can indicate infectious and hematological pathology but it can also be a sign of hyperthyroidism. For this reason, it has been suggested to perform a complete blood count before starting treatment with antithyroid drugs in case of new-onset hyperthyroidism. Antithyroid drugs can cause severe neutropenia, also called agranulocytosis, when the neutrophil count is less than 500/µl. Therefore, the use of these drugs should be reconsidered if it is le...

Introduction: Alemtuzumab is an humanized monoclonal antibody used for treatment of Relapsing remitting Multiple Sclerosis (RRMS). One of its main adverse effects is thyroid dysfunction, being a fluctuating hypothyroidism the most frequent presentation. Sometimes this thyroid disturbance is so significant that it might lead to alemtuzumab withdrawal. We present two Clinical cases of hyperthyroidism secondary to alemtuzumab with different clinical courses. <p class="abstext...
