Dissecting coronary artery aneurysm: a report of two cases

Two cases of sudden, unexpected death resulting from coronary artery dissection have been reported. Since sudden and unexpected death falls within medical examiners' jurisdiction, the systematic autopsy examination of such cases offers an opportunity to evaluate this entity as well as other rare causes of natural death. A review of the literature concerning the subject has been presented.     

RESPONSES OF THE CRIMINAL JUSTICE SYSTEM TO LEGISLATION PROVIDING MORE SEVERE THREATENED SANCTIONS

In 1971, the Tennessee legislature enacted legislation providing for mandatory jail sentences and driver's license revocations for anyone convicted of driving while intoxicated. This new law had no demonstrable impact on the highway traffic fatalities rate-the intended objective. This paper explores the reasons for this apparent lack of impact. Data suggest that, while there was some increase in the severity of sanctions imposed on drunken drivers, there was still a consistent tendency to suspend the jail sentences and grant drivers restricted driving privileges. Nor is there any reason to believe that the police intensified their efforts to apprehend larger numbers of drunken drivers. Thus, the more severe sanctions threatened in the new law were generally mitigated in practice. Some possible interpretations for this are offered.     

POLICE VIOLENCE AS A FUNCTION OF COMMUNITY CHARACTERISTICS

The authors find that existing models concerning police violence are not i designed to explain variation among the states in the rates of police use ‘of deadly force. This variation correlates significantly with numerous cultural attributes of the public. The strongest correlates are with the public rates of violence. Therefore, the authors propose to moody existing modeb, and explain the police use of violence as a response to community characteristics. Where public violence is neither normative nor commonly occurrent. the police will be self-restrained. Where the incidence of violence reveals a common means of conflict resolution, the police will adopt its use. Thus, the police use of violence is a culturally determined characteristic and not a police pathology.     

On the estimation of lay-time by measurements of rigor mortis

Measurements of the torgue to overcome rigor mortis on the legs of 101 male human cadavers at 5 degrees C are reported. There seems to exist an upper limit, which is dependent on the lay-time, above which no value occurs, but below which every value may be found. By calculating the 90% tolerance limits for lay-times grouped at 12-hourly intervals, this upper limit was found to decrease exponentially with lay-time. This may be used for the estimation of maximum lay-times from rigor mortis measurements.
