Introduction: Our aim was to determine the comparable value of thyroglobulin in the washout of lymph node fine-needle aspirate (FNATg) and fine-needle aspiration biopsy (FNAB).Materials and methods: We included 29 patients (37 FNAB) with history of differentiated thyroid cancer who underwent total thyroidectomy and were found to have suspicious cervical lymph nodes during follow-up. The referred population was evaluated on what concerns to gender, age, s...

Introduction: The association of autoimmune diseases in the same individual is common. It is well documented that Graves’ disease (GD) is associated to various autoimmune diseases, including: pernicious anemia, vitiligo, type 1 diabetes, Addison’s disease, systemic sclerosis, myasthenia gravis, Sjogren’s syndrome, rheumatoid arthritis and systemic lupus erythematosus. In addition, primary biliary cirrhosis (PBC) may be associated with rheumatoid arthritis, Sjogr...

Pituitary carcinoma is rare (0.1–0.2% of pituitary tumors), with a poor prognosis. It usually presents as invasive and secretory (ACTH or prolactin) macroadenoma. The diagnosis is confirmed by the presence of metastases. The latency period between the diagnosis of adenoma and carcinoma is variable (9.5 years for corticotrophinoma). The treatment includes surgery, radiotherapy and chemotherapy.We report a 58-year-old male, complaining of visual distu...

Introduction: High-resolution US and US FNA are techniques of great relevance in the evaluation of thyroid nodules. They are being used much more often by endocrinologists all over the world. In our Endocrinology Department, we started them in 2006; since then they have been progressively amplified. We present our results of US FNA performed from January 2007 until December 2009.Patients and methods: Two thousand eight hundred and seventy-seven FNA were ...

Introduction: Turner Syndrome (TS) is associated with cardiovascular anomalies and account for a threefold higher mortality in these women. The most common findings are congenital malformations of the heart (CMH), aortic dissection, valvular heart disease (VHD), hypertension and ischemic heart disease. It has been suggested that the ocurrence of cardiovascular disease in TS women is related to their karyotype and possibly to growth hormone (GH) treatment. Our study aimed to as...

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...

DNA methylation is an epigenetic mechanism of gene regulation that can be modified during intrauterine and postnatal life. Pregnant women with polycystic ovary syndrome (PCOS) present elevated androgen and insulin levels, which can affect the DNA methylation pattern of their offspring. Then, we studied the global DNA methylation pattern (GDNAm) in daughters and sons born to PCOS women compared to controls. Daughters (99 born to PCOS and 87 born to control women) and sons (74 b...

Introduction: The European Society of Endocrinology Clinical Practice Guideline defines follow-up recommendations for AI based on the 1 mg overnight dexamethasone suppression test and the presence of associated comorbidities. Follow-up is not recommended for AI presenting serum cortisol levels post dexamethasone ≤1.8 μg/dl neither those presenting serum cortisol levels post dexamethasone between 1.9–5 μg/dl (defined as ‘possible autonomous cortisol se...

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: Pheochromocytomas are catecholamine-producing tumors originated from the chromaffin cells of the adrenal medulla. Although usually sporadic, this tumors could be associated with germline mutations in about 40% of cases. TMEM127 has recently been identified as a novel gene conferring increased susceptibility to pheochromocytoma.Case report: A 42-year-old woman was referred to our Hospital to perform a right adrenalectomy for pheochromocytoma...
