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 ...

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...

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: Adult-onset autoimmune diabetes (AID) has two different phenotypes: classic type 1 diabetes mellitus (T1DM), with insulin requirement just after diagnosis, and latent autoimmune diabetes in adults (LADA). According to the Immunology of Diabetes Society, LADA diagnostic criteria are: age of onset of 30 years or more, any islet autoantibody, absence of insulin requirement for at least 6 months. The purpose of this study is to characterize patients with AID followed...

Introduction: Primary aldosteronism (PA) is the principal cause of arterial hypertension potentially treatable. The diagnosis is dependent of tests to identify patients who will benefit most with surgical treatment. ACTH stimulation test (AST) has been described as a useful confirmatory test, potentially identifying bilateral disease in patients without adrenal tumors.Aim: Evaluate the AST in patients with hypertension and positive screening test for PA,...

Introduction: Performance-enhancing drug (PED) use is currently a common practice both inside and outside the sports competition scenario, and its adverse health effects remain underappreciated.Case report: We report the case of a 26-year-old man, bodybuilding practitioner, no relevant medical history, family history of autoimmune disorders. Referred to the emergency room with polydipsia, polyuria, blurred vision associated with a post-prandial capillary...

Introduction: The existence of clear differences between the biological course and clinical behaviour of minimally invasive (MI) and widely invasive (WI) follicular thyroid carcinomas (FTC) is still debatable. The present study was conducted to outline the clinical differences between MI and WI-FTC and evaluate outcomes in both tumors.Methods: We conducted a retrospective cohort study involving 80 cases of FTC. The comparison between MI-FTC and WI-FTC in...

Introduction: Pheochromocytoma (Pheo) and paragangliomas (PGL) are rare catecholamine-producing tumors.Near 35% of patients have disease-causing germline mutations.10% are malignant although the malignancy rate differs accordingly to the genetic background.Purpose: This study aims to characterize the sample of patients followed on a tertiary Portuguese Center and associate the presence of genetic mutation with clinical presentation.<p class="abstext"...
