Introduction: Insulinomas are the most frequent cause of endogenous hypoglycaemia. 90 to 95% of these are benign. Surgical enucleation or resection is the standard treatment. Medical therapy focuses mainly on the use of diazoxide with few alternatives in patients with high surgical risk.Case-report: Female patient, 89 years-old, non-diabetic, with previous history of acute myocardial infarction, stroke with motor sequelae, pacemaker carrier and severe ao...

Introduction: Thyroid ultrasonography and fine needle aspiration (FNA) are the most useful techniques in the evaluation of thyroid nodules. They are cheap, fast, minimally invasive and high precision methods. The FNA can be performed by palpation or ultrasound guidance. The use of ultrasound reduces the nondiagnostic results rate. However, the cytologic diagnostic accuracy depends on the technique and pathologist experience. Ultrasonography confirms the presence of a thyroid n...

Introduction: Pheochromocytomas are adrenomedullary catecholamine-secreting tumors. These account for <0.1% of all causes of hypertension and may be related to potentially fatal hypertensive crises. Can appear as sporadic tumors or associated with familial syndromes.Malignancy occurs in 15–20% of the cases and is characterized by local invasion or distant metastasis rather than capsular invasion. Tumor recurrence has been reported with a frequen...

Introduction: Papillary thyroid carcinoma (PTC) is a differentiated thyroid carcinoma and is the most common variant. It is more frequent in women and the median age at diagnosis is 45 years. Most PTC are clinically indolent, have a good prognosis and low incidence of distant metastases. The more frequent locals of distant metastases are bone and lung. Brain metastases are very rare and associated with a poor prognosis.Case report: We present a case of a...

Introduction: Chromogranin A continues to be one of the most valuable markers for neuroendocrine tumors (NETs) however, it has several limitations, including its reduced specificity.Methods: The authors present the case of a patient diagnosed with a midgut NET, during follow-up.Results: Male patient, 61 years old, with chronic renal disease (CRD), underwent right hemicolectomy owing to ileo-cecal valve lesion; hist...

Introduction: Papillary thyroid carcinoma (PTC) and medullary thyroid carcinoma (MTC) are distinct neoplasms, associated with different histological findings. Their coexistence in the same patient is a rare event, requiring a different clinical approach.Clinical case: A 72-year-old patient with no family history of thyroid disease, underwent total thyroidectomy in February 2019, due to toxic multinodular goitre, with no evidence of postoperative complica...

Introduction: Autoimmune Addison disease requires lifelong glucocorticoid and mineralocorticoid replacement. Optimal therapy is not standardized and must balance adequate hormone substitution with prevention of treatment-related complications.Objective: Assessment of patients followed at our department: epidemiology, associated conditions, treatment, cumulative hydrocortisone dose and comorbidities.Methods: Review of clinical recor...

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.<...

Introduction: Cushing’s disease (CD) is a rare disorder caused by an ACTH-secreting pituitary adenoma. Transsphenoidal surgery (TSS) is the recommended first-line treatment. However, an equivocal or even normal preoperative MRI can preclude the surgical management and the outcome of these patients.Objectives: Evaluate the relationship between preoperative MRI and TSS efficacy in patients with CD.Methods: Retrospective cohort s...

Introduction: The prevalence of palpable thyroid nodules in Graves’ disease (GD) is approximately 15%. Cytopathologic interpretation in GD is challenging due to frequent cytomorphologic changes, namely after radioactive iodine (RAI) therapy. Some of the few published studies regarding fine-needle aspiration (FNA) in patients with GD, suggest an increased risk of malignancy of thyroid nodules arising in GD patients. However, the results are inconsistent, and there is no co...
