Endobronchial tuberculosis (EBTB) is defined as a tuberculous infection of the tracheobronchial tree with microbial and histopathological evidence, or without parenchymal involvement. Bronchoscopic appearances EBTB have been divided into seven subtypes: actively caseating, edematous-hyperemic, fibrostenotic, tumorous, granular, ulcerative, nonspecific bronchitic. However, information for establishing definite microbiological diagnosis in each these categories lacking. We aimed to present...

<h3>BACKGROUND:</h3> Patients with COPD face an increased risk of cardiovascular disease and cardiac mortality. Carotid femoral pulse wave velocity (cf-PWV) is a validated measure arterial stiffness, well recognized predictor adverse outcomes, offers higher predictive value than classical factors. We investigated the association between stiffness using cf-PWV as noninvasive technique. <h3>METHODS:</h3> This clinical study was prospective, observational, cross-sectional. Sixty-two subjects...
