Radiology of chronic obstructive pulmonary disease.

This article reviews the radiologic manifestations and complications of chronic obstructive pulmonary disease, particularly those seen in association with emphysema. Current concepts on the pathogenesis of chronic obstructive pulmonary disease are discussed and related to findings on high-resolution CT scan and histologic examinations. Controversial issues concerning the detection and grading of emphysema using radiologic and physiologic tests are also addressed.

Family-focused interventions for survivors of sudden cardiac arrest.

This paper 1) describes what is known about recovery for families of patients who survive sudden cardiac arrest (SCA) and undergo internal cardioverter defibrillator (ICD) implantation, 2) discusses empirical evidence for interventions aimed at affecting recovery following SCA and ICD implantation, 3) presents additional data that suggest interventions for cardiac arrest survivors and their families, and 4) makes recommendations for the development of future intervention programs for SCA survivors and their families. Research supporting the use of educational and support interventions designed for SCA survivors and families is reviewed. Recommendations are made for future design and testing of interventions in the population.
