Introduction: Treatment of hyperthyroidism in older adults is crucial to reduce its morbidity and mortality. Radioactive iodine has been widely used in this age group due to its efficacy, safety and cost-effectiveness.Aim: To determine the efficacy of 131I for treatment of hyperthyroidism in the elderly.Methods: Retrospective study of 86 hyperthyroid patients aged ≥65 years who performed radioiodine therapy. We eva...

Introduction: Bilateral macronodular adrenal hyperplasia is a rare cause of Cushing’s syndrome (CS) characterized by multiple adrenal nodules >1 cm. It can be diagnosed in patients with overt CS but is more often diagnosed incidentally, especially in the 5th or 6th decades of life.Clinical case: 61-year-old woman with type 2 diabetes, arterial hypertension and dyslipidemia treated with metformin+sitagliptin 1000/50 mg bid, valsartan+hydrochlorot...

Background: Diabetes is an important risk factor for major adverse cardiovascular events (MACE). Although the increased risk for MACE is well known, the impact on the in-hospital outcomes remains incompletely understood. Our aim was to evaluate the interrelation between diabetes and MACE in a central hospital in the North of Portugal between 2009 and 2015.Methods: We evaluated retrospectively the hospitalizations due to MACE including stroke or transient...

Multiple benign symmetric lipomatosis (Madelung’s disease, Launois–Bensaude syndrome) is significantly rare disease characterised by symmetrical focal deposition of adipose tissue in the neck, upper part of the arms, back, pelvis, and thigh. Although its etiology is uncertain, it has been associated with genetic factors, mitochondrial inheritance and alcoholism. Its pathogenesis seems to include a dysfunction of cAMP and levels of catecholamines in adipocytes. This c...

Introduction: Pheochromocytomas/paragangliomas are rare neuroendocrine tumors. Although mostly sporadic, about 1/3 of the cases correspond to inherited autosomal dominant syndromes, often associated with germline mutations of the SDHD, SDHC and SDHB genes. The association with the SDHAF2(SDH5) gene has been recently discovered, with only few cases published worldwide, and it presents as a paraganglioma of the head and neck, without previous known description of other locations...

Adrenocortical carcinomas (ACC) are rare and usually very aggressive tumors with heterogeneous outcomes. The individual variability in tumor progression and patients’ survival is linked to ACC biology and molecular heterogeneity, reinforcing the need to identify markers with prognosis value, to allow an accurate clinical strategy. Currently, in the absence of specific molecular markers, ACC prognosis is mainly predicted by the European Network for the Study of Adrenal Tum...

Most of adrenocortical tumors (ACT) are benign and non-functioning tumors, in contrast to adrenocortical carcinomas (ACC), which are rare and usually very aggressive tumors with a poor prognosis. The pathological discrimination between adrenocortical adenomas (ACA) and ACC is mainly based on unspecific and subjective histological features, resulting in inaccurate diagnosis in several cases. Numerous studies have previously described the potential value of immunohistochemistry ...

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...

Berardinelli-Seip syndrome is an autosomal recessive disorder characterized by generalized lipoatrophy, extreme insulin resistance with dyslipidaemia in childhood and development of diabetes and hepatic steatosis in adolescence. The metabolic derangements can be severe and lead to substantial comorbidities, including acute pancreatitis, hepatic cirrhosis, and premature cardiovascular disease. Other manifestations can include polycystic ovarian syndrome, acanthosis nigricans, a...
