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...

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: Intraoperative identification of neck lesions in patients who have undergone previous neck surgery is particularly difficult, because of operative scarring and distorted anatomy. Radioguided occult lesion localisation (ROLL) involves the preoperative intratumoral ultrasound-guided injection of a radioactive tracer. In the present study, we investigated the efficacy of roll in two patients with papillary thyroid cancer (PTC) who underwent previous neck exploration...

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: About 50% of patients with medullary thyroid carcinoma (MTC) have persistent or recurrent disease after surgery.For a calcitonin (ct) value greater than 150 pg/ml, it is suggested by international guidelines performing additional imaging exams (AIE) for evaluating the presence of distant metastasis. It is often difficult to assess the presence of nodal disease and secondary liver lesions (often miliary) by ‘morphological’ imaging ...

Introduction: Smokers around the globe commonly report increased body weight after smoking cessation as a major factor that interferes with their attempts to quit. In addition, numerous controlled studies in both humans and rodents have reported that nicotine exerts a marked anorectic action. Nicotine’s effects on energy homeostasis have been mostly pinpointed in the central nervous system, but the molecular mechanisms controlling its action are still not fully understood...

Introduction: Fine needle biopsy (FNB) is a very important diagnostic tool in the assessment of thyroid nodules and plays a prominent role in therapeutic approach. It has a sensitivity around 83 to 85% and a specificity around 80 to 92%.Aims: To correlate cytological (FNB) and final histopathological data in patients with nodular thyroid pathology.Methods: A retrospective study of patients who underwent surgical procedure from Janu...

Introduction: Gastric endocrine tumors (GET) are rare. Type 1 tumors are non-functioning, almost exclusively benign lesions, usually presenting as multiple polyps, usually <1 cm in diameter, which arise from gastric enterochromaffin-like cells in response to chronically elevated gastrin, secondary to (auto-immune) atrophic fundic gastritis. These tumors were traditionally treated with total gastrectomy, like adenocarcinomas. Currently, surveillance or endoscopic treatment ...
