A forensic case study of a naturally mummified brain from the bushveld of South Africa

The present study reports our observations of a naturally mummified human brain found in the bushveld of South Africa. This case extends the geographic and climatic ranges in which mummified brains have been found, and it represents an additional case where no human activity has led to the mummification. The mummified brain was c. one fifth the size of a normal human brain, while the gyral and sulcal patterns of a typical human brain were clear. CT scanning of the brain revealed that subcortical structures, normally evident in this type of imaging, were not discernable, indicating a slow mummification process. Histological examination of the tissue revealed near complete degradation of the microanatomical structure, with only putative Nissl bodies remaining as identifiable neural microstructures. The specimen appears to have survived several veld fires, as well as a high annual rainfall, and a high relative humidity. It is thought that specific conditions amenable to brain mummification, but not other soft tissues, occurred in the skull of this specimen in the weeks postmortem.     

Reduction of postmortem angiography-induced tissue edema by using polyethylene glycol as a contrast agent dissolver

Postmortem investigation is increasingly supported by computed tomography (CT) and magnetic resonance imaging, in which postmortem minimal invasive angiography has become important. The newly introduced approach using an aqueous contrast agent solution provided excellent vessel visualization but was suspected to possibly cause tissue edema artifacts in histological investigations. The aim of this study was to investigate on a porcine heart model whether it is possible to influence the contrast agent distribution within the soft tissue by changing its viscosity by dissolving the contrast agent in polyethylene glycol (PEG) as a matrix medium. High-resolution CT scans after injection showed that viscosities above c. 15 mPa s (65% PEG) prevented a contrast agent distribution within the capillary bed of the left ventricular myocardium. Thereby, the precondition of edema artifacts could be reduced. Its minimal invasive application on human corpses needs to be further adapted as the flow resistance is expected to differ between different tissues.     

A qualitative analysis of the use of community treatment orders in Saskatchewan

This study examined the opinions of patients who have been placed on a community treatment order (CTO), their relatives, mental health clinicians and representatives of community agencies about the use of CTOs in Saskatchewan. Patients were assessed using indepth interviews, while their relatives, mental health professionals and representatives of community agencies took part in facilitated focus groups. Patients had contradictory feelings about CTOs. Most experienced some degree of coercion while on the orders but many believed that CTOs provided necessary structure in their lives. Clinicians were more consistently positive but recognized the difficult choices in balancing the subject's right to self-determination with the benefits of a treatment order. Family members viewed CTOs as necessary to control a chaotic situation caused by the subject's limited insight.     

Gender disparity in criminal offenses among persons of high IQ

Criminologists have largely neglected deviance among those with high IQs. This work uses Towers's (1988) concept of conventional genius to analyze how deviant behavior varies by gender among genius offenders. Like Bisi (2002), the authors expect female patterns of deviance to be lower than that for males even within this genius sample. Their work finds that male geniuses are significantly more likely to self-report ever having committed violent felonies. Among the authors' conventional genius sample of university students, gender differences in nonviolent felonies, misdemeanor offenses, and unethical behaviors are not significantly different between the female and male respondents.     

Virtopsy hemorrhage of the posterior cricoarytenoid muscle by blunt force to the neck in postmortem multislice computed tomography and magnetic resonance imaging

In forensic autopsies, one of the most important and common signs of violence to the neck is hemorrhages of the soft tissues. The Institute of Forensic Medicine in Bern evaluates the usefulness of postmortem multislice computed tomography (MSCT) and magnetic resonance imaging (MRI) of forensic cases prior to autopsy. The aim of this study was to prove the sensitivity of postmortem MSCT and MRI in the detection of hemorrhages of the neck muscles. A full body scan prior to and a detailed scan of the explanted larynx after autopsy were performed. MSCT detected multiple fractures of the larynx. Detailed MRI was able to demonstrate the hemorrhage of the left posterior cricoarytenoid muscle. The minor hemorrhage of the right posterior cricoarytenoid muscle could not be detected with certainty. Although more experience is required, we conclude that combined MRI and MSCT examination is a useful tool for documentation and examination of neck muscle hemorrhages in forensic cases.     

Influencing retirement behavior: A key issue for social security

Recent trends toward earlier retirement threaten future supplies of labor and the financial stability of many of our public and private pension systems. One of the few federal efforts now in place to reverse this trend has been the 1977 law outlawing mandatory retirement before age 70 for most American workers. This legislation by itself will have little effect on retirement patterns, because strong financial incentives to retire remain imbedded in the system. Changes in the Social Security Act enacted this year begin to recognize these incentives but are highly controversial and at best will not begin to go into effect until 1990. To be successful, efforts of policymakers to increase work at older ages must focus on the financial incentives at the heart of retirement plans rather than on merely attempting to weaken mandatory retirement constraints.
