Abstract

Combined virological and bacteriological studies were carried out in 83 patients with chronic bronchopulmonary diseases. Viral antigens, predominantly respiratory syncytial virus antigen, were detected in 72% of the patients in bronchial material obtained by bronchoscopy. Examinations for antibody of IgM and IgG classes specific for different viruses revealed acute infection in 79% of the patients which coincided with exacerbation of the process due to concomitant ARVD. The other patients had chronic virus infection. The over-time studies confirmed long-term persistence of viruses in bronchial epithelium in 15 patients (in 9 respiratory syncytial, in 5 adenovirus, in 1 parainfluenza virus). Thus, the above results showed respiratory viruses not only to play a role in exacerbation of chronic bronchopulmonary diseases, but in a number of cases apparently to be the main cause of their development.

Arrhythmogenic Right Ventricular Dysplasia

Arrhythmogenic right ventricular dysplasia is a congenital cardiomyopathy that is characterized by infiltration of adipose and fibrous tissue into the right ventricle wall and loss of myocardial cells. Primary injuries usually are at the free wall of the right ventricular and right atria resulting in ventricular and supraventricular arrhythmias.
