We present an unexpected fatal case of pulmonary embolism due to venous thrombosis after vaccination for coronavirus disease 2019 (ChAdOx1 nCov-19). The deceased was a 64-year-old woman with Alzheimer disease. The deceased had fever shortly after vaccination, and presented sudden dyspnea and died 8 days after vaccination. On postmortem examination, pulmonary embolism and venous thrombosis were noted in deep veins of both lower legs. Even though the psychomotor function of the deceased became fragile due to Alzheimer disease, the deceased was not bed-ridden, and major known risk factors related to venous thrombosis were not explicit in this case. Because there are not enough data related to vaccination and thrombosis, we hope that this case would be helpful in unraveling pathogenesis of venous thrombosis after vaccination and in determining whether there is any association between thrombosis and vaccination.

In autopsy practice, we encounter case of suicide or murder using various methods or tools. Damage caused by tools such as a knife or hammer is commonly encountered, but a case of damage using a chainsaw is not commonly encountered. We present an autopsy case of a suicide due to neck injury using a chainsaw. A 56-year-old man was found dead with a neck injury and a chainsaw below him. Soft tissue of the neck, thyroid cartilage, trachea, carotid vessels, cervical vertebrae, and cervical spinal cord were found to be cleaved, and a cogwheel-shaped pattern was observed in the injured area.

Despite being a very new field, forensic imaging is rapidly being used in forensic medical practices around the world. Computed tomography images are being produced and used for many reasons. Forensic imaging is being used for preliminary examination of serious findings before a routine autopsy, as it might help to give positive proof in some cases. Some major preliminary findings, such as brain hemorrhage, cardiac tamponade, or aortic dissection, can then be substantiated with the results of the physical autopsy. Forensic imaging techniques may also provide additive evidence about the cause of death such as pneumothorax, ileus, gas embolism, and aspiration that are difficult to detect with the traditional surgical autopsy techniques. Forensic imaging is also proving useful outside the autopsy room; forensic anthropologists and odontologists are using images to help them determine the age, sex, and even lifestyle of human specimens. Finally, forensic images have also begun to function as a form of record keeping in complex cases.

BACKGROUND: Fibrates are widely used to treat hypertriglyceridemia, a risk factor for arteriosclerosis, but these compounds have been associated with renal dysfunction. This study aimed to investigate the effects of fibrates on renal function in relatively healthy adult subjects with no cardiovascular diseases. METHODS: This retrospective study included 558 outpatients who were prescribed 160 mg fenofibrate (fenofibrate group) or 10 mg atorvastatin (control group) between August 2007 and October 2015. The groups were randomly matched using propensity scores at a 1:1 ratio. Serum creatinine levels and estimated glomerular filtration rates before and after treatment were compared between the two groups. RESULTS: Patients in the fenofibrate group showed greater changes in serum creatinine levels than those in the control group (9.73%±9.83% versus −0.89%±7.37%, P<0.001). Furthermore, 55.1% of patients in the fenofibrate group, but only 6.1% of those in the control group, exhibited a serum creatinine level increase ≥0.1 mg/dL (P<0.001). The fenofibrate group showed significantly greater declines in the estimated glomerular filtration rate than the control group (−10.1%±9.48% versus 1.42%±9.42%, P<0.001). Moreover, 34.7% of the fenofibrate group, but only 4.1% of the control group, exhibited an estimated glomerular filtration rate decrease ≥10 mL/min·1.73 m² (P<0.001). CONCLUSION: Fenofibrate treatment resulted in increased serum creatinine levels and reduced estimated glomerular filtration rates in a primary care setting. Therefore, regular renal function monitoring should be considered essential during fibrate administration.

We report the case of a female who died of suspected acute myocardial infarction. Post-mortem CT angiography (PMCTA) was performed with intravascular contrast infusion before the standard autopsy, and it successfully demonstrated the complete thrombotic occlusion of a coronary artery and also a corresponding perfusion defect on myocardium. We herein describe the PMCTA findings of a cardiac death with special emphasis on the potential benefits of this novel CT technique in forensic practice.

We present the case of a 23-year-old man who suddenly collapsed during a physical altercation with his friends while in a drunken state. The post-mortem computed tomography (CT) with angiography revealed acute basal subarachnoid hemorrhage with rupture of the left middle cerebral artery. On autopsy, the head, face, mandible and neck showed multifocal hemorrhages with fracture of the hyoid bone, and the pathologic findings of the brain was consistent with CT findings. However, the vascular rupture site was not observed macroscopically. On histologic examination, a microscopic focal rupture was identified at the proximal portion of the middle cerebral artery, and possibility of arteriopathy was considered. This case illustrates that other parts of intracerebral arteries (other than the vertebral arteries) can be the culprit of rupture in the case of traumatic basal subarachnoid hemorrhage, and the post-mortem angiographic findings can be helpful in targeting the site of vascular injury. Furthermore, meticulous sampling of intracranial vessels could help find the vascular rupture site and identify any histologic findings suspicious of arteriopathy. Therefore, we suggest that post-mortem angiography can be an effective and adjunctive tool for a tailored approach in finding the vascular injury, and that histologic examination of both the intracranial and extracranial arteries be important to medicolegally ensure the death of traumatic basal subarachnoid hemorrhage and to examine presence of arteriopathy as a predisposing factor.
