Introduction: The aging population brought new challenges in several diseases. Pituitary tumors are usually not related with elderly, although the rise in life expectancy has allowed its diagnosis in unusual age groups.Aim: To describe the pituitary tumors diagnosed in patients with age ≥ 80 yearsMethods: Retrospective observational study which included 23 patients with pituitary tumors with age ≥ 80 years observed in c...

Introduction: Graves’ ophthalmopathy (GO) is an orbital autoimmune disorder closely linked to thyroid autoimmunity, mainly Graves’ disease. After an initial progressive inflammatory period (active phase), GO stabilizes and eventually subsides (inactive phase). Treatment should rely on a thorough assessment of the activity and severity of GO and its impact on the patient’s quality of life. Patients with active, mild disease generally benefit from local therapies ...

Retrospective study of patients with metastatic/progressive pheochromocytoma (PCC) and paraganglioma (PGL) treated with (131) I MIBG in our hospital during 2015–2018 period.Methods: There are no established criteria for establishing PCC/PGL as malignant apart from de presence of metastases at diagnosis. Radionuclide therapy (131) I-metaiodobenzylguanidine (MIBG) is frequently used in this patients when surgery is not possible. Indication of MIBG tre...

Woman, 40 years old. Smoker and habitual drinker, history of toxic consumption, anxiety-depressive syndrome, postsurgical hypothyroidism after total thyroidectomy for multinodular goiter in substitution treatment. Diabetes mellitus type 1 diagnosed in 2001 as a result of pregnancy, unstable, with poor chronic glycemic control, requiring frequent admissions to our hospitalization plant due to episodes of ketoacidosis. It requires high insulin requirements and does not present m...

Evaluation of bone quality represents a challenge since the analysis by bone mineral density (BMD), provides useful but incomplete information. New tools are arising, and amog them, TBS is emerging as a new surrogate marker of bone texture and microarchitecture which may be useful to potentially evaluate the risk of bone fracture and can be obtained from already existing BMD scans. Retrospective study of 23 patients with PHH. Clinical, analytical and BMD data were collected fo...

Introduction: Incidence of Digestive NETs (DNETs) has increased in the last 40 years. Visceral obesity, metabolic syndrome (MetS) and insulin resistance (IR) have been associated with several types of cancer.Aim: To evaluate possible associations of obesity, hyperinsulinemia and IR with well-differentiated (WD) DNETs through a case control study.Materials and methods: Ninety-six patients with gastrointestinal (75.0%) and pNET (22.9...

Introduction: Primary acinic cell carcinoma (ACC) is an uncommon salivary gland (SG) tumor, making up 1–3% of all SG neoplasms, more frequent in women, at 40–60 year old. The cause is still unknown and the only well-established risk factor is ionizing radiation. ACC metastasize in 10–15% of the cases, 35% tends to recur and the rate of disease-associated death is about 16%. Surgical resection is the mainstay treatment, but radiation therapy may be used in some c...

Introduction: Pheochromocytomas and extra-adrenal paragangliomas are rare neuroendocrine tumors, with a peak incidence between the 3rd–5th decades of life and about 10% are malignant. Although they have the same radiographic and histologic characteristics of their benign counterpart, malignant pheochromocytomas are diagnosed by the presence of local invasion or metastatic tumor in the non-chromaffin tissues, and offer a poorer prognosis. Treatment is typically extirpative...

Objective: To study the relation between incretin-based therapies, DPP-4 inhibitors and GLP-1 receptor agonists, and tumor stage at the time of diagnosis of pancreatic and biliary tract cancer.Methods: Retrospective study of type 2 diabetic patients with newly diagnosed of pancreatic or biliary tract cancer attended consecutively in a tertiary hospital between the years 2012 and 2015.Results: A total of 37 patients were included. T...

Background: Pituitary adenomas (PA) are common intracranial tumors that are mainly considered benign. A small group of patients exhibit clinically aggressive behavior sometimes unrelated to the histopathological or radiological features.Methods: Twelve patients were selected harboring a PA with clinical features of aggressiveness. All the patients underwent pre and postoperative endocrinologic/neuroradiologic evaluation.Results: 10...
