Exposure to catecholamines and beta-receptor agonists used routinely during procedures and diagnostic tests can precipitate all the features of stress cardiomyopathy, including cardiac isoenzyme elevation, QTc interval prolongation, and rapidly reversible cardiac dysfunction. These observations strongly implicate excessive sympathetic stimulation as central to the pathogenesis of this unique syndrome.

ABSTRACTMethods: An effective disaster response requires competent responders and leaders. The purpose of this study was to ask experts to identify attributes that distinguish effective from ineffective responders and leaders in a disaster. In this qualitative study, focus groups were held with jurisdictional medical directors for the 9-1-1 emergency medical services systems of the majority of the nation's largest cities. These sessions were recorded with audio equipment and later transcribed.Results: The researchers identified themes within the transcriptions, created categories, and coded passages into these categories. Overall interrater reliability was excellent (κ = .8). The focus group transcripts yielded 138 codable passages. Ten categories were developed from analysis of the content: Incident Command System/Disaster Training/Experience, General Training/Experience, Teamwork/Interpersonal, Communication, Cognition, Problem Solving/Decision Making, Adaptable/Flexible, Calm/Cool, Character, and Performs Role. The contents of these categories included knowledge, skills, attitudes, behaviors, and personal characteristics.Conclusions: Experts in focus groups identified a variety of competencies for disaster responders and leaders. These competencies will require validation through further research that involves input from the disaster response community at large.(Disaster Med Public Health Preparedness. 2010;4:332-338)

Introduction:The blackout in North America of August 2003 was one of the worst on record. It affected eight United States states and parts of Canada for >24 hours. Additionally, two large United States cities, Detroit, Michigan and Cleveland, Ohio, suffered from a loss of water pressure and a subsequent ban on the use of public supplies of potable water that lasted four days. A literature review revealed a paucity of literature that describes blackouts and how they may affect the medical community.Methods:This paper includes a review of after-action reports from four inner-city, urban hospitals supplemented accounts from the authors' hospital's emergency operations center (emergency operations center).Results:Some of the problems encountered, included: (1)lighting; (2) elevator operations; (3) supplies of water; (4) communication operations; (5) computer failure; (6) lack of adequate supplies of food; (7) mobility to obtain Xray studies; (8) heating, air condition, and ventilation; (9) staffing; (10) pharmacy; (11) registration of patients; (12) hospital emergency operations center; (13) loss of isolation facilities; (14) inadequate supplies of paper; (15) impaired ability to provide care for non-emergency patients; (16) sanitation; and (17) inadequate emergency power.Discussion:The blackout of 2003 uncovered problems within the United States hospital system, ranging from staffing to generator coverage. This report is a review of the effects that the blackout and water ban of 2003 had on hospitals in a large inner-city area. Also discussed are solutions utilized at the time and recommendations for the future.Conclusion:The blackout of 2003 was an excellent test of disaster/emergency planning, and produced many valuable lessons to be used in future events.
