Introduction: Pheochromocytomas (PHEO) and paragangliomas (PGL) are rare catecholamine-secreting tumors. Some authors proposed that there is a positive linear relationship between tumor size and measurements of metanephrines and an absence of association with catecholamine levels.Objectives: To review and characterize patients diagnosed with PHEO and PGL in Garcia de Orta Hospital. To determine the relationship between tumor size and measurements of urin...

Background: Acromegaly most commonly results from an excess production of GH and secondary increase in IGF1. More than 95% of the time from the pituitary gland, but the source of excess GH secretion may not necessarily be pituitary in origin. Ectopic acromegaly may arise due to neuroendocrine tumors by production of GHRH and in <0.5% of the cases from ectopic pituitary remnants in the sphenoid sinus.Clinical case: We present a case of a 37 years old ...

Objective: To evaluate the response to treatment with insulin infusion pumps by the evolution of HbA1c over 8 years of experience.Methods: Observational retrospective study. We evaluated the response to treatment in 122 patients with type 1 diabetes recruited between 2004 and 2012 in our area.Results: Between 2004 and 2012, 122 pumps have been implemented (average of 17.4 pumps/year). The number decreased to only four in 2012. Pres...

Objective: To evaluate the efficacy of liraglutide, a new glucagon-like peptide 1 analogue, on glycaemic control, body weight, blood pressure and lipid profile in obese patients with type 2 diabetes mellitus (T2DM).Material and methods: Patients attending a tertiary Endocrinology Unit who were prescribed liraglutide (January 2013–December 2013) and assessed both at baseline and first post-initiation visit were included in the analysis. The primary e...

Introduction: Most obese subjects have a normal thyroid function. Despite that, serum TSH seems to be slightly higher in this population, with a positive correlation with the degree of obesity.Objective: Evaluation of the relationship of serum TSH with BMI, weight, and HOMA-IR in euthyroid obese subjectsMethods: Three hundred obese subjects attending an Obesity Outpatient Clinic and submitted to bariatric surgery between January 20...

Obstructive sleep apnoea (OSA) is very common in severe obese patients and has been related to insulin resistance (IR) and hyperleptinemia, and these findings may have effects on food behavior and obesity complications. In order to explore this relationship and the role of sex we have studied 531 patients with morbid obesity (BMI 42.8+6.5 kg/m2). A full polysomnographic study and glucose, insulin and leptin measurements as well as air displacement plethysmography we...

Introduction: Isolated ACTH deficiency (IAD) is a rare entity characterized by secondary adrenal insufficiency with low levels of serum cortisol, decreased production of ACTH, adequate secretion of other pituitary hormones and normal pituitary structure on radioimaging. Due to the rarity of its occurrence the prevalence of IAD as a cause of secondary adrenal insufficiency has not been determined. To our knowledge 200 cases are described in the literature. Impairment of GH secr...

Hyperfunctional nodules of the thyroid are rarely associated with thyroid cancer, for these reason are rarely biopsied. Although multiple theories have being proposed, the relationship is still uncertain. After performing a MEDLINE literature search, we found in multiple retrospectives analysis, that patients with hyperthyroidism with hyperfunctional nodules have an estimated of 0.3–16.3% prevalence of malignancy. In our study forty-eight hyperthyroid cases were prospecti...

Introduction: Graves’ and Hashimoto’s diseases are considered two extremes of the same autoimmune thyroid disease. Spontaneous conversion from hypothyroidism to hyperthyroidism is uncommon. On the other hand, Graves’ disease typically improves during pregnancy and worsens after delivery. We describe a patient with an unusual course of thyroid disease during pregnancy.Case report: An 33-year-old woman, with a two-year history of hypothyroid...

The thyroid pathology is an area of special interest in our department. Hyperthyroidism represents 3.4% of the 8144 patients followed.The aim of this study is to characterize the therapeutic approach in patients with Grave’s disease (GD) and toxic nodular disease (TND).Retrospective study of 217 patients diagnosed with GD and TND, evaluated according parameters of therapeutic option, efficacy, relapse rate and associated compl...
