Postmortem changes in porcine eyes on computed tomography images.

Porcine eyes were examined using postmortem computed tomography (PMCT) under controlled postmortem time and temperature conditions to assess the mechanisms and timing of changes in ocular structure. Eight porcine heads were halved, and PMCT scans were conducted from postmortem interval (PMI) days 0 to 13. CT images were obtained to evaluate the vitreous volumes, vitreous CT values, axial lengths of the eyes, lens dislocation, and intraocular gas.

Postmortem temporal chest CT and its pathological correlation in piglets.

Post-mortem computed tomography (PMCT) is a useful tool to investigate the cause of death. To appropriately use PMCT for cause-of-death analysis, it is necessary to know natural courses after death such as hypostasis in the lungs. We aimed to investigate the natural time-course change of postmortem chest CT findings and its pathological correlation in piglets.

"Shock kidney-like Appearance": Objective evaluation of renal color changes in hemorrhagic shock deaths.

Severe bleeding due to various traumatic injuries can cause hemorrhagic shock, which is difficult to diagnose using forensic medicine. Therefore, we defined the difference in color between the renal cortex and medulla observed in hemorrhagic shock deaths as "shock kidney-like appearance (SKLA)" and digitally analyzed the color difference with a digital camera and color analysis software. The aim of this study was to develop and evaluate a method for objectively determining SKLA and improve the accuracy of forensic diagnosis.

Massive bleeding from an infected pseudoaneurysm in an arteriovenous graft that resulted in death: A case report.

We report an autopsy of a death due to a ruptured infected pseudoaneurysm; a man in his 70s was found dead with massive bleeding from the shunt of his right arm. Autopsy and pathological examination revealed that the cause of death was hemorrhagic shock due to rupture of an infected pseudoaneurysm. Ruptured aneurysms and pseudoaneurysm are a complication of dialysis, and death is rare because they are treated immediately on discovery.
