Background: Amiodarone is an antiarrhytmic drug used mainly in atrial fibrillation. Amiodarone-induced thyrotoxicosis (AIT) is less common than hypothyroidism, but it represents a true therapeutic challenge. AIT can be due iodine load (type 1) or a destructive thyroiditis (type 2).Methods: Retrospective study of patients with AIT, diagnosed between 2010 and 2015, in a central hospital. We reviewed medical records regarding age, gender, amiodarone therapy...

Background: Type 2 diabetes and Hipertension are common in obese patients. Bariatric surgery is effective in sustained weight loss, but also improves glycemic and hypertension control. A high percentage of diabetes remission occurs.Methods: Retrospective study of type 2 diabetic patients submitted to bariatric surgery between 2006 and 2013 in a central hospital. Primary endpoint was evaluation of diabetes and hypertension remission, 2 years after surgery...

Introduction: Germline mutations in tumour suppressor gene PTEN cause heterogeneous phenotypes, that comprise the spectrum of PTEN-hamartoma tumour syndrome (PHTS). Manifestations include macrocephaly, developmental delay, cutaneous lesions, intestinal polyposis and increased risk of neoplasms. Thyroid nodules are identified in about 75% of patients and follicular cell-derived cancer affects 35% of cases, some of which diagnosed as early as 7 years old.C...

Introduction: Ghrelin gene products ghrelin and obestatin have apparent opposite orexigenic and anorexigenic effects, although this latter has not been firmly demonstrated for obestatin in humans. So far, no information has been reported in relation to its potential association to metabolic syndrome (MS).Objective: To study obestatin concentrations in relation to nutritional parameters and eating behavior in old women.Methods: One ...

Introduction: Acromegaly is a rare disease which results from a GH producing adenoma. Around 70–80% are macroadenomas. The therapeutic options currently available are surgery, radiotherapy (RT) and medical treatment (MT). According to literature microadenomas have a higher remission rate, around 80%.Methods: A retrospective chart review of the patients with acromegaly treated in our centre from 1976 to 2011 was performed. In terms of disease control...

Introduction: Patients bearing thyroid cancer that have already gone into surgery and 131I therapy that in the follow-up have high thyroglobulin levels and negative 131I whole body scan represent a diagnostic and therapeutic challenge. 99mTc HYNIC Octreotide recognizes somatostatin receptors that are expressed in thyroid cancer. The objective of this paper is to evaluate these patients by means of 99mTc HYNIC Octreotide and to correlate the results with other imaging methods.<...

Introduction: Primary Hyperparathyroidism (pHPT) is a calcium metabolism disease, resulting from one or more parathyroid glands hyperfunction. Ultrasonography and Technetium Sestamibi are, nowadays, the first line imaging techniques for diagnosis. Recently, a 4-dimensional computed tomography (4D-TC) protocol has emerged, presented in the last endocrine surgery guidelines. It is a dynamic imaging exam based on the parathyroid contrast uptake pattern, whose sensitivity and spec...

Somatotropin is essential not only for linear growth but also for important metabolic functions. Its deficiency is usually the first and most common endocrinopathy induced by cancer disease and its treatments, mainly cranial irradiation. Although somatotropin replacement therapy is safe and effective in promoting a better linear growth, studies of final height in childhood cancer survivors treated with somatotropin are limited. This study was performed to examine growth outcom...

Introduction: Ectopic thyroid tissue is a rare embryonic developmental defect that occurs during the thyroid transition from its initial position in the floor of the primitive bowel to a pre-tracheal location. This defect has a prevalence in the general population of 0.3–1/100,000 inhabitants, increasing to 0.5–1/4,000 patients with thyroid pathology. It is more common in women and can be diagnosed at any age, with diagnosis being more common in young individuals.</p...

Introduction: Ophthalmopathy and dermatopathy are the most frequent manifestations of Graves Disease (GD). It is also known the relation between GD and other autoimmune diseases like myasthenia gravis. Thymus hyperplasia in GD is already documented on literature but it’s mechanism is not well understood. There are two possible explanations, one related to thyrotrophin receptors stimulation present on thymus, and other related to tissue stimulation due to generalized hyper...
