RESUMO
Near-infrared spectroscopy is a device used to determine whether traumatic intracranial hemorrhage has occurred and is primarily used for screening in emergency situations. In this study we examined the applicability of this equipment in postmortem inspection. This study included 124 autopsy cases and 59 postmortem inspection cases performed in the National Forensic Service from July 2017 to October 2018. We carried out the test using Infrascanner Model 2000 (Infrascan Inc.). Autopsy cases were divided into four groups (epidural hemorrhage or subdural hemorrhage group, traumatic subarachnoid hemorrhage or cerebral contusion group, nontraumatic intracerebral hemorrhage group, and control group) and analyzed. There was no difference in the test results according to the presence and type of intracranial hemorrhage. The possibility that variables related to postmortem change affected the test results was considered. In conclusion, this study confirmed that near-infrared spectroscopy is not suitable for the detection of traumatic intracranial hemorrhage in postmortem inspection.

RESUMO
Acute myocardial infarction is one of the most common causes of unexpected deaths, but there are limitations to its diagnosis in postmortem inspection. In this study, we aimed to investigate the usefulness of cardiac marker analysis for the diagnosis of acute myocardial infarction in postmortem inspection. This study was conducted on 30 postmortem inspection cases conducted by the National Forensic Service from 2016 to 2018. Tests for three myocardial enzymes (myoglobin, creatinine kinase-MB, and cardiac troponin I) were performed in each case, and the relationships between enzyme levels, cause of death, and factors affecting the postmortem tests were analyzed. Cardiac enzyme concentrations were not significantly different between the heart disease group and other disease groups, and the false-positive rate was increased due to postmortem changes. Therefore, we can conclude that it is not appropriate to use cardiac enzyme analysis for the diagnosis of acute myocardial infarction in postmortem inspection.
