Does wallerian degeneration of the pyramidal tract affect stroke rehabilitation outcome?
After stroke, apparent WD of the pyramidal tract may slow functional recovery but does not limit final rehabilitation outcome of pure motor hemiparesis. Study of the mechanisms of compensation for this delayed pyramidal tract degeneration will enhance the scientific basis for rehabilitation.
Children with acute asthma and symptoms of VRI respond less effectively to β(2)-agonists after 6, 12, or 24 hours and thus may benefit from more intense therapy and monitoring.
