Abstract:
In 2005, the National Association of Medical Examiners approved the Forensic Autopsy Performance Standards. Standard B3.7 indicates that a forensic pathologist shall perform a forensic autopsy when the death is by apparent intoxication by alcohol, drugs, or poison.The Jefferson County Coroner/Medical Examiner Office has observed an increase in our caseload by 10% per year since 2012. We designed a study to determine if a pathologist could correctly classify the cause of death (COD) and manner of death (MOD) of suspected drug-related deaths without information from the internal examination. The determination of the COD and MOD was then compared with the case file, which includes information from the internal examination and microscopy, to determine agreement between the case file and the reclassification. The percent correct for COD and MOD was calculated, and kappa values were calculated for MOD.The pathologists were able to correctly classify the COD in 73% of cases. For MOD, 2 pathologists achieved substantial agreement between the test cases and the actual case file. The third pathologist had moderate agreement. These findings indicate that a full postmortem examination is necessary to correctly classify the COD/MOD in cases of suspected drug toxicity.Our null hypothesis is that a full autopsy is not necessary to correctly classify the COD and MOD in cases of drug toxicity.

Overview of Cell Death
Cell death was observed in the early 19th century, but there was no experimental evidence to prove it. In 1842, Carl Vogt first discovered cell death in a metamorphic toad; however, it was not termed ‘cell death.’ Scientists discovered different cell death pathways only in the...
Toxic Reactions: Overview
Toxicity falls into two primary categories: local and systemic.
Local toxicity appears at the exposure site, such as protein denaturation caused by caustic substances.
In contrast, systemic toxicity requires the toxic agent's absorption and distribution,...
