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="...

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.Clinical case: Female patient, 19 years old, presented with a clinical history with 2 years of evolution, characterized by episodes of palpitations, headache, nausea and abdominal d...

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...

Background: Pituitary adenomas (PAs) in the elderly, defined as people older than 65 years, represent less than 10% of all PAs. Because of increasing life expectancy and improving health care, diagnosis PAs in this age group is increasing with time. Age-related changes and associated diseases may significantly modify the clinical presentation in these patients, delaying the diagnosis of PAs.Objective: To analyse the clinical features of PAs in elderly pa...

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 ...

Introduction: Langerhans cell histiocytosis (LCH) is a rare disorder characterized by proliferation/accumulation of cells phenotypically similar to skin Langerhans cells. Clinical presentation and aggressiveness are very heterogeneous, from benign to disseminated forms that cause significant morbi-mortality, particularly endocrine failures.Case 1: A 15-year-old Caucasian woman presented with a 14-month history of headaches, secondary amenorrhea. She repo...

Background: Recent studies have shown that the incidence of differentiated thyroid cancer (DTC) is increasing.Objective: Evaluate the incidence of DCT in a center of the south of Spain for the last 15 years and analyse the clinical and morphological factors related to DTC.Methods: We reviewed the series of patients undergoing thyroid surgery at our hospital over a 15-year period and identified patients with DTC. Patients were divid...

Introduction: Medullary thyroid carcinoma (MTC) occurs in a hereditary pattern in 25% of cases. Virtually all patients with multiple endocrine neoplasia 2A (MEN2A) develop MTC. MTC aggressiveness and natural history varies according to the RET mutation. Prophylactic thyroidectomy may cure and/or prevent metastatic disease in most cases.Case report: A 27-year-old man with past history of colostomy at 5 months of age for Hirschsprung disease and t...

Introduction: Individuals with Turner syndrome (TS) are prone to develop autoimmune conditions. The most frequently found are Hashimoto’s thyroiditis, type 1 diabetes, coeliac disease, and inflammatory bowel disease. In patients with TS, Addison’s disease isolated or combined with other autoimmune disease as type 2 polyglandular autoimmune syndrome, is a rare finding.Case report: We report a case of a 41-year-old female patient, with severe ast...
