Atypical entrance gunshot wounds may be produced by deflected or ricocheting bullets. One special type of atypical entrance wound involves abrasion of the skin at a site that is remote from the point of dermal penetration. These remote abrasions, termed "tumbling abrasions," are produced by bullets that tumble after impact with an intermediate target. Three cases of tumbling abrasions are presented.  相似文献

The Healthcare Educational and Research Foundation (HERF) in Minneapolis undertook a two-year research project to study the effects of health maintenance organizations (HMOs) and competition on the hospital industry in Minneapolis/St. Paul. This article summarizes HERF's major findings surrounding three key questions: (1) do the HMOs in Minneapolis/St. Paul use fewer hospital resources relative to conventional payers?; (2) do recent overall community trends in inpatient use suggest evidence of hospital utilization-reducing effects attributable to HMOs?; and (3) given the highly visible competitive process among Minneapolis/St. Paul providers, do hospital cost and revenue data suggest any evidence of cost-containment? The findings (based on data through 1982) indicate that for comparable patients, Twin Cities HMOs appear to use fewer medical care resources per hospitalized patient. There was, however, no clear evidence of community-wide, utilization-reducing effects directly attributable to the "competitive effect" of HMO introduction and development in the market. In addition, there was no empirical evidence that HMOs (which had enrolled 25 percent of the consumer market by 1982), or other large buyers of inpatient services, have selected hospitals on the basis of price as hypothesized by competition advocates.  相似文献

A large number of corpses transferred to Athens and the Piraeus Morgue from abroad have been examined in second autopsies. Lack of information, mistakes in data, useless effort, and disappointment on the part of the forensic pathologists because of the lack of new information revealed are characteristic of these cases. With some exceptions, the second autopsy provided no news for the anxious relatives, who, for the most part, had been prompted by their attorneys or other "well-meaning friends" to demand a second autopsy on the corpses of their loved one (who generally died on board ship abroad). Nevertheless, in 10 of 59 cases, the cause of death was completely different from the determined in the autopsy performed abroad or assumed from the information available. This fact ensures that any corpse from abroad undergoes a careful and thorough examination on its arrival in Greece.  相似文献

Discharge of a shotgun with a shotgun casing in its muzzle as a "dust cover" produced a pattern of injuries suggestive of combined intermediate- and distant-range wounds.  相似文献
