Myopericarditis Complicated With Cardiac Tamponade Due to Infection.

About 90% of cases of acute pericarditis have an idiopathic or viral etiology. In some cases, it is possible to identify high-risk patients for whom hospital admission and specific etiology research are mandatory for adequate treatment. Bacterial pericarditis is uncommon and responsible for less than 1% of cases.

Predictive value of antinuclear antibodies in autoimmune diseases classified by clinical criteria: Analytical study in a specialized health institute, one year follow-up.

Introduction: Determination of antinuclear antibodies (ANA) by indirect immunofluorescence (IIF) is usually the initial test for the diagnosis of systemic rheumatic diseases (SRD). Assigning predictive values to positive and negative results of the test is vital because lack of knowledge about ANAs and their usefulness in classification criteria of SRD leads to inappropriate use.

Methods: Retrospective study, ANA tests requested by different specialties, correlation to patients' final diagnosis.

[The importance of multi-imaging diagnosis in cardiology].

Cardiovascular imaging is one of the disciplines in cardiology with the most recent advances. This means that the teaching of Cardiology must evolve in the same way. In 2009, the American College of Cardiology published a statement, which points out that all of the cardiology residents must have basic training in every one of the cardiovascular imaging modalities available.

[On the actual nomenclature of myocardial infarcts].

Certain criteria are examined for infarctions currents defined as inferior or inferolateral. To do this, certain considerations on the anatomical aspects of isolated and in situ heart are laid out. The topographical relationship of the in situ heart with other adjacent thoracic organs is described.

[The impact of detecting endothelial dysfunction in atherosclerosis: Role of positron emission tomography (PET)].

The endothelium plays an important role in the regulation of the intracellular fluid, vascular permeability, and modulation of vascular focal tone and angiogenesis. Endothelial dysfunction is manifested by the loss of the endothelium ability to modulate physiology changes in its vascular bed, and actually it is considered a prognostic marker of coronary artery disease. The relevance of assessing endothelial dysfunction relies in that it has been observed in different pathologies like DM, dyslipidemia, hypertension, tabaquism and in immunologic diseases like antiphospholipid syndrome and systemic lupus.

Uncommon congenital and acquired aortic diseases: role of multidetector CT angiography.

State-of-the-art multidetector computed tomographic (CT) technology has replaced invasive angiography for evaluation of patients suspected to have aortic disease. Although most aortic disease is associated with atherosclerosis (ie, aneurysms and dissection), the spectrum of aortic disease is vast and includes various congenital and acquired entities. Radiologists should also be familiar with uncommon aortic diseases, which are divided into those that are congenital in origin and acquired disorders, and with their findings at multidetector CT.

[Clinical features of Wegener granulomatosis and microscopic polyangiitis in Chilean patients].

Background: Systemic vasculitis are a group of heterogeneous diseases characterized by inflammation and necrosis of blood vessel walls. The etiology is not known, but geographic and environmental factors are implicated.

Aim: To describe the clinical features of microscopic polyangiitis (MPA) and Wegener's granulomatosis (WG) in a Chilean cohort of patients.
