Pulmonary vascular obstructive disease developed postoperatively in an infant with aortopulmonary transposition and intact ventricular septum who underwent a Mustard operation in 3 months of age. Preoperative catheterization had shown normal pulmonary artery pressures. Four months after surgery, catheterization showed pulmonary artery systolic pressure above the systemic level and a tortuous, a...

BACKGROUND AND AIM The multi-drug resistant-1 (MDR-1) gene is located on human chromosome 7 and encodes a glycosylated membrane protein that is a member of the ATP-binding cassette transporters superfamily. The aim of the study was to reveal the role of the C3435T MDR-1 gene polymorphism in chronic obstructive pulmonary disease. METHOD DNA samples from 41 patients with chronic obstructive pul...

BACKGROUND The World Health Organization has estimated that by 2030, chronic obstructive pulmonary disease will be the third leading cause of death worldwide. Most knowledge of chronic obstructive pulmonary disease is based on studies performed in Europe or North America and little is known about the prevalence, patient characteristics and change in lung function over time in patients in develo...

The advent of respiratory failure is an important indicator of prognosis in the late natural course of chronic obstructive pulmonary disease. The course of 30 patients with c h i c obstructive pulmonary disease following the first episode of respiratory failure has been documented. The data presented are consonant with a severely restricted life expectancy following the first episode of respira...
