Although chronic obstructive pulmonary disease (COPD) has a public health importance similar to asthma, it has received less attention. The first guideline on the management of COPD was released in 1987 by the American Thoracic Society. In 1992 the Canadian Thoracic Society released its guidelines. ⋯ These COPD guidelines show many similarities but also have some interesting differences. The aim of this paper is to review these similarities and discrepancies. Like all guidelines, COPD guidelines suffer from the limited amount of evidence-based medicine supporting them, a limitation that, however, provides a strong stimulus for further research.

Reports of the characterization and understanding of bronchiolitis obliterans organizing pneumonia (BOOP) have continued at an accelerated rate for several years. The radiographic and high-resolution CT features of BOOP continue to be documented. There have been new insights into the pathogenesis of BOOP. ⋯ Childhood BOOP has been described in several reports. Idiopathic BOOP continues to be the most common type; however, a variety of clinical settings such as inhalation of mold spores and associated disorders such as renal transplantation continue to be described. This paper provides an update of advances in the pathogenesis, radiographic features, clinical course, and categorization of the heterogeneity of BOOP.
