Editor's note     
This study applies Elisabeth Noelle‐Neumann's spiral of silence theory to the controversial issue of whether children with AIDS should be allowed to attend public school. The study tests the theory's hypotheses in light of two content analyses of the media's treatment of the issue. The findings offer tentative and qualified support for Noelle‐Neumann's theoretical propositions about the relationship between individuals' perceptions of the issue and the media's tenor of the issue; particularly that of television. The findings suggest the need to address the role of other agents of influence, including reference groups, and to use time‐based data to unravel the causal order of the relationships.  相似文献

Salmonellae most commonly cause uncomplicated cases of gastroenteritis but have a predilection for damaged blood vessels, especially those damaged by atherosclerosis. The abdominal aorta is most frequently affected. The most serious complication of aortitis is mycotic aneurysm formation with subsequent rupture. The authors present the case of a 61-year-old man who was found unresponsive at home 3 days after discharge from the hospital for treatment of gastroenteritis with bacteremia. Postmortem examination revealed a ruptured mycotic aneurysm with a large retroperitoneal hematoma. Numerous gram-negative rods were embedded in the wall of the aorta and surrounding inflammatory infiltrate, compatible with the patient's previously isolated. Whereas abdominal aortic aneurysm rupture is most commonly associated with atherosclerosis, the isolation of from blood cultures, coupled with radiographic evidence of gas surrounding the aorta, should raise the suspicion of infectious aortitis. Whereas fatal rupture of an aortic aneurysm secondary to atherosclerosis alone or in conjunction with aortitis will not have an impact on the manner of death, infections are reportable and thus have public health implications.  相似文献

Death resulting from ruptured cerebral artery aneurysm: 219 cases   总被引:1,自引:0,他引:1  
To characterize the demographics of ruptured cerebral artery aneurysm as a cause of death and to examine the effect of improved diagnostic and therapeutic techniques on the incidence of sudden death associated with the condition, the authors reviewed 219 autopsies performed at the Dallas County Medical Examiner's Office between 1977 and 1997 in which the cause of death was ruptured cerebral artery aneurysm. Ruptured cerebral artery aneurysms accounted for 1.5% of 15,033 natural deaths and 0.4% of all deaths (45,492) followed by autopsy during this period. The majority (56%) of cases occurred in females, with Caucasian females composing the largest group (38%). Seventy-seven percent of cases occurred in individuals between the ages of 31 and 70 years, with the highest concentration in the 41- to 50-year decade (29%). The most common location for ruptured aneurysms was the middle cerebral artery distribution (39%). Multiple aneurysms occurred in 22 (9.1%) cases. Other factors, such as medical history, coexisting disease, symptoms, activity at onset of symptoms, survival time, and toxicology results are also presented. Compared with literature reports before 1980, when ruptured cerebral artery aneurysms were reported as the cause of death in approximately 4% to 5% of sudden natural deaths, the results of this study suggest that despite improved diagnostic and therapeutic techniques during the past two decades, morbidity and mortality from ruptured aneurysms remain a significant health problem.  相似文献
