Myocardial Extracellular Volume Is Not Associated With Malignant Ventricular Arrhythmias in High-risk Hypertrophic Cardiomyopathy.

Introduction And Objectives: Myocardial interstitial fibrosis, a hallmark of hypertrophic cardiomyopathy (HCM), has been proposed as an arrhythmic substrate. Fibrosis is associated with increased extracellular volume (ECV), which can be quantified by computed tomography (CT). We aimed to analyze the association between CT-determined ECV and malignant ventricular arrhythmias.

The upper airway and obstructive sleep apnea in morbidly obese women.

Study Objectives: We are currently carrying out a study on the changes of the upper airway in morbidly obese women and the relationship of the upper airway with the severity of obstructive sleep apnea syndrome (OSAS). This study is similar to the study by Fogel RB et al, which appeared in Sleep 2003;2:150-5.

Design: Patients underwent a cardiorespiratory polygraphic sleep study, respiratory function test (spirometry, plethysmography, arterial blood gas analysis), and computed tomographic studies of the upper airway.

Behçet's disease involving the breast.

Behçet's disease is a vasculitis of unknown origin that was traditionally defined by oral and genital ulcers and uveitis. We describe a case of a patient with a diagnosis of Behçet's syndrome who presented a palpable lesion in the right breast with inflammatory signs. X-ray findings posed a differential diagnosis between tumoral and inflammatory pathology.
