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: Pituitary adenomas (PA) are common intracranial tumors that are mainly considered benign. A small group of patients exhibit clinically aggressive behavior sometimes unrelated to the histopathological or radiological features.Methods: Twelve patients were selected harboring a PA with clinical features of aggressiveness. All the patients underwent pre and postoperative endocrinologic/neuroradiologic evaluation.Results: 10...

Introduction: During childhood and puberty, growth hormone(GH) is essential for linear growth. Consequently, children with isolated GH deficiency(GHD) must receive replacement therapy. GH has also important metabolic actions. GHD in adults is associated with altered body composition. However, long-term consequences of GH treatment in adults is not sufficiently known.Objective: To evaluate GH treatment during pediatric age in patients with isolated GHD.</...

Current lifestyle, characterized by physical inactivity and a poor diet, is heavily linked with an increased incidence of metabolic diseases. One of the most serious silent co-morbidities of those diseases is infertility. The hormonal link between food intake and energy homeostasis is mediated by the leptin ghrelin axis. Compelling evidence suggests that direct leptin’s action regulates cellular glucose homeostasis and mitochondrial biogenesis. We have recently shown that...

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: One of the most common endocrine complications of anorexia nervosa (AN) is the decrease in bone mineral density. The authors evaluated the predictive factors of osteopenia and osteoporosis in AN patients admitted with low weight.Patients and methods: Retrospective analysis of 45 patients admitted with AN between 2001 and 2015 in the Endocrinology department, corresponding to 63 admissions. Bone mineral density was classified according to WH...

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="...
