Comparative Study
Clinical presentations of elderly patients at emergency departments: a comparison between a medical center and a community hospital.
The utilization of emergency services is expected to increase in parallel with an increase of the elderly population. This article compares the elderly patient Emergency Department (ED) utilization at a 3500-bed medical center with that of a 600-bed community hospital serviced by the same group of emergency physicians. ⋯ Significant differences reflected the different roles between the Linkou and Keelung CGMH EDs. Hospital EDs should be prepared to adapt to meet the needs of the elderly based on their roles in the medical care system, at the elderly population grows in the 21st century.

Case Reports
Paradoxical cerebral air embolism after removal of a central venous catheter: case report.
Paradoxical cerebral air embolization through a residual tract after the removal of a central venous catheter is a serious complication of central venous cannulation. Air embolisms resulting from residual catheter tracts in general patients and in single lung transplant patients have been reported. The generally accepted mechanism of this complication is failure of a spontaneous collapse or thrombotic obliteration of a well-formed catheter tract. ⋯ In this article, we report on cerebral air embolization as a complication with the removal with a central venous catheter in a patient with bullous emphysema. A high degree of suspicion and a prompt diagnosis are required for successful application of established therapy. Simple prophylactic procedures and constant awareness of the unusual mechanism of air embolism remain the best treatment.
