3-Iodothyronamine (T1AM) is a recently discovered compound which can be regarded as a novel hormone, since it is an endogenous relative of thyroid hormone with systemic distribution, which does not interact with thyroid hormone receptors, but rather with specific G protein-coupled receptors. T1AM has been reported to modulate energy metabolism, and in rodents chronic T1AM treatment has been associated with lipolysis and decreased body weight. T...

Introduction: Retrospective study, 2003–07, of 619 GDM women.Patients and methods: Two groups according to pre-pregnancy BMI: Go ≥30, Gno <30 kg/m2. Influence of BMI in: family history of DM, previous GDM or macrossomia, gestational age at time of GDM diagnosis, weight gain, blood pressure, A1c, need and doses of Insulin, time and type of delivery, new- born weight, complications and re-evaluation post partum.<p class="abste...

Introduction: Primary hyperparathyroidism (PHP) results from an excessive secretion of parathyroid hormone (PTH), typically leading to hypercalcaemia. This disorder is more common than previously expected, since it is frequently diagnosed in asymptomatic patients.Objectives: To characterize a group of patients with PHP, in what concerns to: age, clinical presentation, biochemical and imaging evaluation, treatment and evolution.Pati...

Introduction: Primary hyperparathyroidism (PHPT) is the most common cause of hypercalcaemia in the outpatient setting. Surgical remove of an adenoma or hyperplastic glands results in cure, but an accurate localization, preoperative whenever possible, is essential for success. Taking into consideration that parathyroid carcinoma is a rare event, FNA of parathyroid glands, complemented by PTH measurement in washouts (FNA/PTH), may be a useful tool in the diagnostic workout.<...

Introduction: TSH-secreting adenomas represent <2% of pituitary tumors. Surgery and/or radiotherapy are primary treatment options. Somatostatin analogues and also dopamine agonists, represent valuable alternatives or adjuvant therapies.Objective: To report a case of euthyroidism and tumor stability achieved in a TSH-secreting pituitary macroadenoma, treated with octreotide-LAR, as first line therapy, and then added cabergoline. To review the efficacy...

Objective: Aromatase, the key enzyme involved in estrogen synthesis, is expressed in a variety of cells, including peripheral blood leukocytes (PBLs), and tissues. The systematic study of aromatase expression and activity in different tissues in the human and other primates, however, is difficult and still missing. Although is not really known, aromatase expression in PBLs could be used as parameter of aromatase expression/activity making PBLs a potential alternative for other...

Introduction: Adrenal hematomas are very rare entities. They occur often associated with: trauma, anticoagulation, coagulopathy, septicemia, pregnancy complications or tumors. When none of these predisposing factors is present, diagnosis and treatment can become a real challenge.Case report: A 19-years-old woman presented with complaints of asteny, loss of appetite, loss of 10 kg in a month, and pain in right lumbar and abdominal regions. No other compla...

Pheochromocytomas are rare, catecholamine-secreting, adrenal neoplasms. In about 25% of cases they arise in patients with germline mutations. Malignancy occurs in about 10%.We retrospectively analysed the records of patients with histological diagnosis of pheochromocytoma submitted to adrenal surgery between 1987–2008 and followed in the Endocrinology department.Thirteen patients were included. We evaluated age on diagnosis; c...

Background: Von-Hippel-Lindau disease (VHL) is a rare (1/36.000 newborns), autosomal, dominant inherited tumour syndrome. A germline mutation in VHL tumour suppressor gene predisposes carriers to tumours in multiple organs. In the presence of positive family history, it can be diagnosed clinically in a patient with at least one typical VHL tumour.Clinical report: In December 2007, a 34 years-old women presented with palpitations and tachycardia, but norm...

Introduction: Type 1 diabetes is one the most common chronic diseases found in children and youngsters.Objectives: Characterization of a sample of young type 1 diabetic patients, treated with multiple daily injections of insulin.Patients and methods: Analysis of patients files with ages between 11 and 26 years observed on diabetology consultation during the first semester of 2008, with diagnosis of diabetes for at least 6 months. P...
