Observed Characteristics of Suicidal Hangings: An 11-year Retrospective Review

Many studies have been published regarding suicidal hanging deaths, and most forensic pathologists and coroners are very familiar with such causes of death. Forensic pathologists are challenged over their rulings regarding manner of death in part because the general public has a limited scope of knowledge. One such challenge centers on the question of whether a hanging can be a suicide if the individual is not fully suspended. The authors designed a retrospective study to review suspension in hangings and to analyze other criteria used to help in deciding manner of death. We examined 229 suicidal hanging deaths over an 11-year period (1997 through early 2009) using the data from two separate jurisdictions in Ohio. In conclusion, we found that the vast majority (83.4%) of people who hanged themselves were found partially suspended. Among other criteria analyzed, only the presence of petechial hemorrhages and acute neck injury was statistically significant.     

Discovery of decomposed and mummified corpses in the domestic setting--a marker of social isolation?

Mass media reports attribute the occurrence of decomposed or mummified corpses in a domestic setting mainly to an increasing social isolation of elderly people. Not much is known about the demographic and medical conditions under which individuals are found months or even years after death in their homes. For this study, autopsy reports of individuals found dead and mummified or decomposed between 1993 and 1997 with those from 1963 to 1967 were retrospectively analyzed. Between 1993 and 1997, a total number of 320 individuals were found decomposed at home compared to 412 such cases between 1963 and 1967. The proportion of individuals older than 64 years was significantly higher during the 1990s study period. Furthermore, the proportion of deaths attributable to natural causes was significantly lower during the 1990s, whereas the rate of suicides was nearly three times higher.     

The most severe chronic organ findings in official public health autopsies--a medico-sociologic contribution

At the Vienna Institute, in the year 1986, 79 carcinoma findings were recorded in 1736 cases of natural death. The most common were carcinomas of the respiratory and gastrointestinal tracts. Seventeen unidentified tumors were found to have been the cause of death. Public health autopsies, therefore, contribute to the clarification of tumor disease and thus to cancer statistics. Although diagnosed fatal cancer cases correspond to only 0.33% of all cancer deaths in Vienna, the question arises why a patient with very advanced cancer is not under medical care and why the affliction is revealed only in autopsy, the purpose of which is to elucidate sudden, unexpected deaths. The comparatively few individual cases should nevertheless give cause for reflection and are discussed from a medicosociological view, taking into consideration the statistical and epidemiological data relating to cancer diseases.     

Air embolism following arthroscopy--autopsy findings and forensic medicine aspects

An iatrogenic cause of air embolism with a fatal outcome is reported that occurred in a case in which arthroscopy of the knee had been carried out. Even after worldwide use of arthroscopy for many years, this complication has never been seen until now. At autopsy, when air bubbles were observed in the right heart chamber and in the vena cava inferior, only the knee joint was taken into consideration as the air-access route. The access of air was detected by means of arthroscopy on the corpse, combined with a special autopsy technique and shown experimentally. Insufflated air had entered via a fracture of the tibial articular surface and then passed through the spongiosa into the femoral vein. These findings are of far-reaching clinical consequence because the indication for arthroscopy by gas insufflation must be reconsidered again. Finally, the medicolegal aspects of such an incident are discussed.     

Politics and the New American Welfare States

Federal law allows states to create new welfare policies determining who can receive welfare, what types of clients are exempted from new welfare work requirements, and the value of cash benefits. This project tests nine different theoretical explanations of welfare policy to explain why states have reacted differently to this new authority. We test these explanations on Temporary Aid to Needy Families (TANF) policies promulgated between 1997 and 2000. Our findings confirm the strong role of race in TANF politics that Soss et al. (2001) recently reported, but we also find that other constituent characteristics, and institutions, paternalistic goals, and state resources have a consistent influence on welfare policy. These results indicate that different approaches to welfare are attributable to the unique, and very potent, combination of political characteristics in each state.     

Secondary ion mass spectrometric characterization of nail polishes and paint surfaces

A variety of paint and fingernail polish samples, which were visually similar, but had different chemical compositions and formulations, was analyzed using quadrupole static secondary ion mass spectrometry (SIMS). Coating distinction was easily achieved in many cases because of the presence of dominant ions derived from the components of the coating, which could be observed in the SIMS spectra. In other instances, coating distinction was difficult within a product line because of spectral complexity; for this reason and because of the large numbers of spectra generated in this study, multivariate statistical techniques were employed, which allowed the meaningful classification and comparison of spectra. Partial Least Squares (PLS) and Principal Component Analysis (PCA) were applied to quadrupole SIMS data. PCA showed distinct spectral differences between most spectral groups, and also emphasized the reproducibility of the SIMS spectra. When using PLS analysis, reasonably accurate coating identification was achieved with the data. Overall, the PLS model is more than 90% effective in identifying the spectrum of a particular coating, and nearly 100% effective at telling which coating components represented in the PLS models are not present in a spectrum. The level of spectral variation caused by sample bombardment in the SIMS analysis was investigated using Fourier transform infrared spectroscopy (FT-IR) and quadrupole static SIMS. Changes in the FT-IR spectra were observed and were most likely a result of a number of factors involving the static SIMS analysis. However, the bulk of the sample is unaltered and may be used for further testing.     

Suicide of a body packer

The smuggling of illicit drugs by means of body packing has become a common problem at European airports. Europe is considered to be the fastest growing market for cocaine worldwide, and the air route is the most frequently used method of trafficking cocaine. Smuggling illicit drugs by use of body packing is considered to be a high toxicological hazard because of the risk of leakage or a package bursting. We report about the first case of suicide of a body packer by re-ingesting the content of excreted cocaine packages. The consequence of this case is that the death scene investigation and autopsy assessments in case of a body packer's death should always consider the possibility of re-ingested packages. Detention personnel should be instructed by forensic and criminalistic experts to take preventive measures.
