An unusual shotgun injury pattern produced by an intermediate target

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.     

The "empty heart" sign

Approximately 15% of victims of instantly lethal central nervous system trauma have an empty or nearly empty heart at autopsy. This article defines and discusses the "empty heart" sign.     

Wrongful termination lawsuits: the employers finally win a few

Much attention has been given of late to the erosion of the "employment-at-will" doctrine. Exceptions to this doctrine began to emerge when courts held that at-will employees could sue if their termination violated public policy. The at-will doctrine was further eroded by court rulings that a contract requiring good cause in order to terminate could be inferred from employee handbooks, company personnel policies, and circumstances of employment. As the initial flood of wrongful termination lawsuits now reaches the appellate level, some guidance on the standards employers must observe can be drawn from court decisions. The authors examine these decisions as well as the legislative reform being proposed in response to them.     

Practitioner fraud and abuse in medical benefit programs: government regulation and professional white-collar crime

Physicians who defraud and abuse medical benefit programs provide a unique group of lawbreakers for scientific study. They could be considered to epitomize white collar criminals given their exceedingly high socioeconomic status and power as a professional group. Using official reports and documents, as well as interviews with enforcement and program personnel at both state and federal levels, this study examines the problem of physician fraud and abuse in Medicare and Medicaid. Major areas relevant to understanding this phenomenon and its control are presented and policy implications of present knowledge in the area are discussed.     

Early postmortem course of washerwoman's skin of the fingers

Studies were carried out systematically in both corpses and the hands of corpses in order to find out when " washerwoman 's skin" begins. The temperatures ranged between 10 degrees and 18 degrees C and the time of the experiments did not exceed 300 min. The initial formation of washerwoman 's skin could be observed after 20-30 min at the fingertips and after 50-60 min in the entire finger. The longest intervals observed were 100 or 150 min, respectively. These long intervals were interpreted as being exceptions from the norm, probably due to either extraordinarily heavy strips of fat on the fingers or abnormally hard skin on the hands. The course of washerwoman 's skin obviously depends on the water temperature, and afterwards it disappears rather slowly--even after a short immersion--in the open air. We will carry out additional experiments in the future.     

Growth behavior of the blue blowfly Calliphora vicina maggots

Fifty-three clusters of blowfly eggs of the genus Calliphora vicina were observed in the laboratory up to the hatching stage under reproducible and virtually field-like conditions. Rearing the larvae was then continued up to pupation, the larval growth in length being recorded several times a day. As the object was to study the dependence of the larvae increase in length on the temperature conditions in vitro, the substratal humidity and food supply were kept unchanged during the entire study. The temperature ranged from 6.5 degrees C to 35 degrees C, with the temperature for the individual cluster kept constant during the entire developmental process. Data on about 5500 measured larvae were statistically evaluated. The basic result established was that in the case of the blowfly of the genus Calliphora vicina in vivo, all developmental stages relevant to the entomologic determination of the time of death depend on the temperature conditions: (1) the duration of the egg stage increases with decreasing temperature; (2) the speed of larval growth is slower at lower temperatures; (3) the maximal larval length is reached earlier at higher temperatures; (4) the mean value of maximal length decreases with increasing temperature; (5) larvae under all temperature conditions decrease in size after having reached their maximal length, the decrease in length being more rapid at higher temperatures; (6) constant temperatures over 30 degrees C lead to "stunted forms" which do not pupate and die; (7) constant temperatures under approximately 16 degrees C after the peak of growth has been reached inhibit the readiness to pupate, which causes the larvae to fall into a stationary state of rest, which will be interrupted only when the temperature is raised and resumption of the metamorphosis is thus induced. To allow rapid reconstruction of the larval age in general practice, the established growth data were set out in the form of a diagram designated isomegalendiagram, which permits temperature-fluctuation-related entomologic determination of the time of death with a maximum degree of accuracy.
