Introduction: Factitious hypoglycemia results from surreptitious administration of insulin or insulin secretagogues. It can involve non-diabetic individuals with knowledge of hypoglycemiant drugs, or diabetics manipulating the doses.Clinical case: A 42-year-old women, type 1 diabetic since the age of 14, on intensive insulin therapy (A1C: 8.5%), was hospitalized for study of recurrent severe hypoglycemia in the last 2 months, despite successive insulin d...

Introduction: The syndrome of late-onset hypogonadism (LOH) is a clinical and biochemical syndrome associated with advancing age male, characterized by typical symptoms and decreased serum concentrations of testosterone, which can affect multiple organ systems and may impair quality of life. The prevalence of LOH syndrome is higher in certain patient groups, obese, diabetic and suffering from erectile dysfunction manifest LOH at higher rates than the general population.<p ...

Introduction: Radioiodine (RAI) therapy is an inexpensive and reliable therapeutic option for Graves’ disease (GD). However, individual characteristics of the disease can influence therapeutic success. The identification of these factors may help to predict outcome and select optimal pre-treatment conditions.Aim: To assess clinical, laboratory and radioactive parameters that may lead to RAI treatment failure in patients with GD....

Introduction: Methimazole is the thionamide compound most used in the treatment of hyperthyroidism due to its efficacy, commodity and security. Severe side effects are rare, although potentially fatal: agranulocytosis in 0.1–0.5% and toxic hepatitis in 0.1%Aims: To characterize the patients admitted in the endocrinology ward for the last 10 years for severe complications of methimazole therapy.Material and Methods: Retrospecti...

Introduction: Cinacalcet is an oral calcimimetic indicated in treatment of primary hyperparathyroidism if patients do not accept surgery, do not carry out the surgical criteria, there is failure of previous surgery or serious comorbidity that makes surgery impossible.Methods: Descriptive study that included 20 patients with primary hyperparathyroidism who had complete at least 12 months of treatment with cinacalcet for different reasons (eight patients r...

Introduction and objective: CD36 is a scavenger receptor that facilitates the membrane transport of long chain fatty acids into muscle and adipose tissue. Polymorphisms in this gene have been related to abnormal serum fatty acids and obesity-related phenotypes with inconsistent results. Gene-diet interactions could modulate these associations. Our aim was to study whether a common functional variant (rs1761667) in this gene will associate with anthropometric variables and plas...

Introduction: Everolimus is a drug selective inhibitor of mTOR and approved by the FDA in 2011 for treatment of neuroendocrine tumors of pancreatic origin unresectable. Our objective was to evaluate the efficacy and safety of everolimus in a patient with malignant pancreatic head insulinoma.Case: This is a 31 year old man who complains of epigastric pain, dizziness, sweating and syncope related to exercise. During admission is objectively severe hypoglyc...

Introduction: During a normal menstrual cycle, serum levels of luteinizing hormone (LH), follicle-stimulating hormone (FSH), estradiol (E2), and progesterone (P4) can vary widely between cycles for the same woman, as well as between different women. Reliable reference values based on the local population are important for correct interpretation of laboratory results.Aims: To evaluate the discrepancy of the results on fertility hormones by two different t...

Introduction: Sleep disordered breathing (SDB) promotes structural myocardial changes and can trigger cardiac arrhythmias. Acromegalic patients have high prevalence of SDB and GH–IGF1 excess is related to a specific cardiomyopathy characterized by concentric cardiac hypertrophy and diastolic dysfunction. The aim of this study was to assess the relationship between SDB and cardiac dysfunction on acromegalic patients.Material and methods: Observationa...

Introduction: Generously supported by IPSEN)-->Prolactin (PRL) -secreting adenomas are about 40% of all pituitary adenomas. Their clinical symptoms are mainly related to development of secondary hypogonadism and/or tumor mass effects. Dopamine agonists (DA) are first-line drugs for prolactinoma patients due to their effectiveness in normalizing PRL levels and shrinking tumour mass. Surgery is an option for DA failure or tumour mass e...
