ReviewCurrent issues in postmortem imaging of perinatal and forensic childhood deaths.
Perinatal autopsy practice is undergoing a state of change with the introduction of evidence-based cross-sectional imaging, driven primarily by parental choice. In particular, the introduction of post mortem magnetic resonance imaging (PMMR) has helped to advance less-invasive perinatal autopsy in the United Kingdom (UK) and Europe. However, there are limitations to PMMR and other imaging techniques which need to be overcome, particularly with regard to imaging very small fetuses. ⋯ Different imaging modalities and their relative advantages and disadvantages are discussed, together with other benefits of more advanced cross-sectional imaging which currently lie in the research domain. Whilst variations in local imaging service provision and need may determine different practice patterns, and access to machines and professionals with appropriate expertise and experience to correctly interpret the findings may limit current practices, we propose that gold standard perinatal and pediatric autopsy services would include complete PMMR imaging prior to autopsy, with PMCT in suspicious childhood deaths. This approach would provide maximal diagnostic yield to the pathologist, forensic investigator and most importantly, the parents.

Frequency of forensic toxicological analysis in external cause deaths among nursing home residents: an analysis of trends.
There is a paucity of research examining the utility of forensic toxicology in the investigation of premature external cause deaths of residents in nursing homes. The aim of this study is to describe the frequency and characteristics of toxicological analysis conducted in external cause (injury-related) deaths amongst nursing home residents in Victoria, Australia. This study was a retrospective cohort study examining external cause deaths among nursing home residents during the period July 1, 2000 to December 31, 2012 in Victoria, Australia, using the National Coronial Information System (NCIS). ⋯ The use of toxicological analysis varied by cause of death with a relatively low proportion conducted in deaths from unintentional falls (n = 286, 24.9%) and choking (n = 36, 40.4%). The use of toxicological analysis decreased as the decedents age increased. Forensic toxicology has the potential to contribute to improving our understanding of premature deaths in nursing home residents however it remains under used and is possibly undervalued.
