Introduction and objective: Prophylactic central lymph node dissection (CLND) in patients with suspected papillary thyroid cancer (PTC) without evident lymph node metastasis (LNM), remains debatable. We propose to evaluate whether BRAF V600E mutation presence, could help to identify patients at risk for LMN.Methods: Retrospective study of patients with diagnosis of PTC, who underwent total thyroidectomy during 2002 and 2013 (n: 256) in our hospi...

Objective: To investigate factors associated with the presence and growth rate of thyroid nodules(TN) in patients with acromegaly.Methods: We retrospectively evaluated the medical records of 52 patients with acromegaly followed in our institution (University Hospital Ramón y Cajal). The frequencies of TN and papillary thyroid cancer (PTC) and potential factors associated with nodular thyroid disease (NTD) were investigated. In patients with NTD (<em...

Introduction: Type 2 diabetes mellitus (T2DM) is a chronic disease, with prevalence increasing worldwide and its complications are major causes of early morbidity and mortality. Recent guidelines suggest the individualisation of glycaemic targets and glucose-lowering therapies.The aim of this study was to determine the quality of care provided to type 2 diabetic patients in our institution, analysing metabolic control, cardiovascular risk factors and pre...

Introduction: Acromegaly is a rare disorder and sporadic cases are the most frequent. It can also occur in association with genetic syndromes, such as Carney complex, multiple endocrine neoplasia type 1 (MEN-1), MEN-1 like syndrome, isolated familial acromegaly and familial isolated pituitary adenomas.Case report: Thirty five -year-old man was observed in 1994 for gynecomastia. Acromegaly was diagnosed based on clinical, biochemical (IGF1 1094.7 ng/ml, b...

Introduction: Moderate weight loss (5–10%) translates into health benefits, including improvement in cardiovascular risk. It is essential to assess the results and indicators of success in treating obesity, which is the objective of this work.Methods: A retrospective study of patients with overweight and obesity, followed in Nutrition consultation between 2004 and 2010. We analyzed biodemographic and anthropometric variables, consultation reason and...

Providing good information, exchanging expertise and stimulating clinical discussions are usually main goals when structuring academic services. Nowadays, especially in large countries with social/economic differences between regions, such as Brazil, telemedicine and telehealth are resources with main strategic importance in a country’s Public Health System. Since its creation, RUTE network (Rede Universitária de Telemedicina, supported by brazilian Ministry of Scien...

The steroid 17α-hydroxylase enzyme CYP17A1 exerts two distinct activities that catalyze conversion reactions at key branch points in steroidogenesis. CYP17A1 17α-hydroxylase activity is the key step in cortisol synthesis whereas CYP17A1 17, 20 lyase activity generates sex steroid precursors. Inactivating CYP17A1 mutations result in CYP17A1 deficiency (17OHD), a rare form of congenital adrenal hyperplasia that classically presents with combined glucocorticoid and sex ...

Introduction: Thyroid nodules in children and adolescents are less prevalent, but entail greater risk of malignancy than in adults. Most are asymptomatic because they are associated with normal thyroid function, but their prevalence is increasing due to the incidental diagnosis by neck ultrasound.Aims: To evaluate the characteristics of a pediatric population with thyroid nodules submitted to fine-needle aspiration (FNA) biopsy.Met...

Introduction: People with intracranial organic lesions, including pituitary tumours, may manifest initially as a psychiatric disorder, such as depression, emotional disturbance, anxiety, apathy, neurobehavioral disturbance, cognitive dysfunction and personality disturbance.Case Report: A male patient 45 years old was sent to the Department of Endocrinology of São João Hospital due to a pituitary macroadenoma. The patient referred asthenia, musc...

Introduction: Transsexualism associates biological normality with the conviction of belonging to the opposite sex and the gender reassignment request. The therapy includes psychological, hormonal and surgical treatment.
