Introduction: Breast cancer is the second most common neoplasm in women. Hormonal replacement therapy and combined hormonal contraception are established extrinsic hormonal risk factors for breast cancer. Therefore, the increase in the prevalence of infertility and the use of assisted conception techniques have raised questions regarding the potential risk of hormone-dependent neoplasms. We report the case of a woman diagnosed with bilateral metastasized breast cancer soon aft...

Background: Low serum testosterone (LST) is associated with some chronic diseases, changes in body composition and resistance to insulin. Diabetes is one condition that has high prevalence of LST.Objetive: To determine the prevalence of LST in men with diabetes and its relationship with age, anthropometric and biochemical data.Material and methods: A cross-sectional study of 65 men with type 1 and type 2 diabetes was conducted, wit...

Background: In the recent years, Vitamin D role has grown in cardiovascular and inflammatory diseases, and some relations were made with low serum testosterone (LST) levels. It is equally known that in patients with diabetes, the prevalence of LST is higher.Objetive: To determine the prevalence of low levels of vitamin D and its relation with LST in men with diabetes.Material and methods: A cross-sectional study of 65 men with type...

Background: Amiodarone is a potent antiarrhythmic drug used to treat tachyarrhythmias. However, is linked to a number of adverse effects, including thyroid dysfunction. It is the main cause of drug-induced thyrotoxicosis. Here we report a clinical case of amiodarone-induced thyrotoxicosis (AIT) in a patient with complex ventricular dysrhythmia.Case report: A 23 years-old women with dilated cardiomyopathy, severe depression of ejection fraction of left ve...

Introduction: Pheochromocytoma is a rare catecholamine-secreting tumor that arises from the chromaffin tissue of the adrenal medulla. Of the reported cases, only 10% consist in bilateral lesions and the probability of multiple endocrine neoplasia should always be investigated.Case report: Female patient, 19 years old, presented with a clinical history with 2 years of evolution, characterized by episodes of palpitations, headache and abdominal discomfort....

Introduction: Primary adrenal insufficiency or Addison disease (AD) is a potentially fatal condition if not diagnosed in time. Rarely, it can arise as a manifestation of antiphospholipid syndrome (APS), caused by adrenal venous thrombosis and consequent hemorrhagic infarction.Case report: We present the case of a 36-year-old caucasian woman with APS diagnosis since she was 24, with history of arterial hypertension and multiple thrombotic events (deep vei...

Introduction: Neuroglucopenic hypoglycaemia might be an underestimated threat of bariatric surgery, as Roux-en-Y gastric bypass (RYBG) or gastric sleeve. We aimed to evaluate glucose variability after bariatric surgery by continuous glucose monitoring (CGM) in a real-life setting.Methods: CGM was used in twelve patients with clinical suspicion of hypoglycaemia after undergoing bariatric surgery (RYBG or sleeve), during seven days. CGM was through using i...

Introduction: Craniopharyngiomas are rare epithelial tumors of the sellar and parasellar region, with high survival rates but with frequent tumor recurrence or persistence.Methods: Information collection from clinical records and review of the epidemiology, diagnosis, treatment and follow-up of patients with diagnosis of craniopharyngioma followed in an Endocrinology Department between 1980 and 2015. Statistical analysis using SPSS v. 22.0.<p class="...

Background: Optimal management of type 1 diabetes requires full understanding of the relationships between the triad: HbA1c, fasting plasma glucose, and glucose variability (GV). As GV may contribute to HbA1c we assessed the influence of GV in HbA1c levels.Research design and methods: We retrospectively analysed 9393 h of continuous glucose monitorings (CGMs) from 61 patients with type 1 diabetes. Periods of 24 h with missing values were excluded. We cal...

Introduction: Cushing’s disease (CD) is characterized by increased secretion of ACTH often as a result of a pituitary adenoma. The surgical success rates after transsphenoidal pituitary surgery (TSS) range from 53 to 96% in different centres. Postoperative cortisol levels have been proposed as the standard criteria for prediction of surgical remission however, this variable is subject of a variety of interferences.Objectives: Evaluate the potential ...
