OBJECTIVE Several studies have provided prevalence estimates of posttraumatic stress disorder (PTSD) related to the September 11, 2001 (9/11) attacks in broadly affected populations, although without sufficiently addressing qualifying exposures required for assessing PTSD and estimating its prevalence. A premise that people throughout the New York City area(More)
BACKGROUND Various organizations and universities have developed competencies for health professionals and other emergency responders. Little effort has been devoted to the integration of these competencies across health specialties and professions. The American Medical Association Center for Public Health Preparedness and Disaster Response convened an(More)
Effective preparedness, response, and recovery from disasters require a well-planned, integrated effort with experienced professionals who can apply specialized knowledge and skills in critical situations. While some professionals are trained for this, others may lack the critical knowledge and experience needed to effectively perform under stressful(More)
To date, results of laboratory and clinical investigations suggest that transcutaneous pO2 measurements hold considerable promise as a technique for evaluating the adequacy of cutaneous circulation. The advantages of this technique are that it is simple to use, noninvasive and does not require the use of radioactive isotopes. Since the available data are,(More)
BACKGROUND The American Heart Association Caruth Initiative (AHACI) is a multiyear project to increase the speed of coronary reperfusion and create an integrated system of care for patients with ST-elevation myocardial infarction (STEMI) in Dallas County, TX. The purpose of this study was to determine if the AHACI improved key performance metrics, that is,(More)
The physiological effects of increased tissue pressure were studied using a model system in which known pressures were applied uniformly to the hindlimbs of rabbits for a period of 5 h. Muscle blood flow was monitored using a new argon washout technique. Muscle pO2, pCO2, and pAr were measured using a Teflon membrane catheter-mass spectrometer system. The(More)
Computers, personal digital assistants (PDA), and the Internet are widely used as resources in medical education and clinical care. Educators who intend to incorporate these resources effectively into residency education programmes can benefit from understanding how residents currently use these tools, their skills, and their preferences. The researchers(More)
Increased tissue pressure is an important cause of local circulatory compromise. In both rabbit and human model systems known external pressures were applied to otherwise normal limbs. Side-by-side comparison of the wick and the infusion techniques revealed that both methods of pressure measurement yielded essentially identical results when tissue pressure(More)
1. We studied the relationship between transcutaneous oxygen tension at the foot and local arteriovenous pressure difference in 15 normal men and women; arteriovenous pressure difference was varied by changing the height of the foot with respect to the heart and by applying external pressure to the foot. 2. Control transcutaneous oxygen tension was 67 +/- 9(More)
BACKGROUND The diagnosis of posttraumatic stress disorder (PTSD) has remained controversial from the time of its first inclusion in DSM-III. No reviews have fully documented the shifting PTSD definitions across editions of the criteria. This article chronicles the evolution of PTSD across editions of the DSM. METHODS Diagnostic precursors to PTSD in DSM-I(More)
