In a role reversal at Shriners Hospital for Children, above, patients Lizette Ortiz, 18, left, Juan Carlos Urrutia, 6, and Francisco Soto, 14, put plenty of casts on public relations director Doug Boudreaux Thursday. At right, Juan Carlos listens to the pulse of physical therapy aide Dave Powell. Doctors and other staffers became patients for an afternoon, and the patients became doctors and nurses, taking the opportunity to "diagnose" staff members, take temperatures, hook up IVs and apply bandages. The hospital employees were dressed in scrubs and wheeled out on gurneys to await the patients' "treatment."
