Introduction: Graves’ disease (GD) is a systemic autoimmune disease characterized by lymphocyte activation and synthesis of anti-TSH receptor antibodies (TRABs). Higher values of TRABs are associated with a higher risk of Graves’ ophthalmopathy and dermatopathy. Iodine-131 therapy (RAI) is one of the well-established options in GD, but it can cause a transient increase in TRABs.Objectives: To evaluate the evolution of TRABs after RAI; to identi...

Introduction: Parathyroid carcinoma (PC) is an extremely rare malignancy. A complete surgical excision is often difficult, and persistent/recurrent disease occurs in up to 65% of cases. Progression often leads to symptomatic hypercalcemia, the major contributor to poor quality of life and mortality. Treatment options beyond surgical resection are limited. Denosumab is an approved therapy for refractory hypercalcemia of malignancy, and its use in unresectable PC has been descri...

Introduction: Obesity is a chronic disease associated with multiple comorbidities, defined by BMI, without considering the metabolic state of the patient. There are few data on the proportion of obese patients without metabolic syndrome (MS).Objective: To characterize patients considered to be metabolically healthy (MH) followed at the obesity outpatient clinic of one University Hospital, and to compare this group with a group of obese patients with MS.<...

Type 1 diabetes mellitus (T1D) is an autoimmune disease that results from the destruction of insulin producing β cells, in genetic susceptible individuals. Vitamin D (Vit D) is mostly known for its role in bone and calcium metabolism, however it is also involved in the modulation of the immune response. Serum levels of vitamin D partly depend on diet and sunlight exposure. However, genetic factors are also involved. Patients with T1D have been reported to have a higher pr...

Introduction: Continuous subcutaneous insulin infusion (CSII) therapy in type 1 diabetes (T1D) reduces the risk of hypoglycemia. Hypoglycemia remains a treatment-limiting factor. Impared hypoglycemia awareness (IHA) occurs in 25% of T1D cases and seems to be underestimated by continuous glucose monitoring (CGM). Glycemic variability (GV) is a increasingly valued parameter as a predictor of hypoglycemia and risk of chronic complications.Objective: Analysi...

Introduction: Inferior petrosal sinus sampling (IPSS) has been considered to be the gold standard for differential diagnosis of Cushing’s Disease (CD) and ectopic ACTH secretion (EAS).Aim: To describe the experience of our centre in performing IPSS, its safety and efficacy; assess remission rates from transphenoidal surgery and clinical course; approach to the difficulty in the etiological diagnosis of ACTH-dependent Cushing’s Syndrome.<p c...

Introduction: Polycystic ovary syndrome (PCOS) is a frequent cause of infertility. Its influence on the results of in vitro fertilization (IVF) is controversial, and generally not isolated from the effect of obesity. A relationship between the FSH receptor (FSHR) polymorphism Asn680Ser and the risk and phenotype of PCOS has been studied with conflicting results.Objectives: To analyze the influence of obesity and PCOS on the gonadal axis...

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: 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...
