Review Case Reports
Fatal airway obstruction due to Ludwig's angina from severe odontogenic infection during antipsychotic medication: A case report and a literature review.
Ludwig's angina is characterized by inflammation of the sublingual and submandibular spaces and is mainly caused by odontogenic infection, which leads to cellulitis of the soft tissues of the floor of the mouth and the neck. This causes asphyxia due to elevation and posterior deviation of the tissues of the floor of the mouth. We report a fatal case of airway obstruction due to Ludwig's angina. ⋯ There was also cellulitis and abscess of the facial, suprahyoid, and neck musculature, which suggested that the cause of death was asphyxiation due to airway obstruction. This was an alarming case, with mental illness leading to risk of severe odontogenic infection, and in which obesity and use of antipsychotic medication might have acted synergistically leading to airway obstruction. This is also a case of Ludwig's angina captured by PMCT, which has rarely been reported.

Self-immolation is a rare suicide method in the developed countries of the western world (0.06-1%); however, it has relatively higher prevalence rates in the developing countries of Asia and Africa (6-57%). The present study aims to examine self-immolation suicides within the Greek mainland (Attiki, Thrace, and Peloponnese) over a period of 9 years (2011-2019) in order to investigate the phenomenon in the Greek population forensically, identify the characteristics and motivations of suicide victims, explore its associations to socio-cultural or psychiatric factors, and describe a fatal case of suicide by self-immolation that was partially recorded on camera. The medical files (autopsy reports) of cases performed at the Departments of Forensic Medicine of the National and Kapodistrian University of Athens, Democritus University of Thrace, and the Forensic Service of Messinia-Peloponnese were retrospectively examined yielding 19 cases of suicides by self-immolation. ⋯ Unlike other countries, there was no significant association with domestic or sexual violence, social or political protest, or religious issues. Therefore, the suicide victims preferred secluded or private outdoor locations (not public). Findings deriving from the examined variables localize Greek population culturally between the Western European and Asian African countries, but with its own idiosyncrasies.

A Holistic Multi-Scale Approach to Using 3D Scanning Technology in Accident Reconstruction.
Three-dimensional scanning and documentation methods are becoming increasingly employed by law enforcement personnel for crime scene and accident scene recording. Three-dimensional documentation of the victim's body in such cases is also increasingly used as the field of forensic radiology and imaging is expanding rapidly. These scanning technologies enable a more complete and detailed documentation than standard autopsy. ⋯ Two competing scenarios were considered for the vehicle speed calculation: the pedestrian being projected forward by the impact or the pedestrian being carried on the vehicle's bonnet. In order to assist with this, the impact area of the accident vehicle was scanned using laser surface scanning, the victim was scanned using postmortem CT and micro-CT and the data sets were combined to virtually match features of the vehicle to injuries on the victim. Micro-CT revealed additional injuries not previously detected, lending support to the pedestrian-carry theory.

Finland has one of the highest homicide rates in Western Europe, and almost every tenth homicide is caused by asphyxiation. Reliable statistics, a strict legislation, and an exceptionally high medico-legal autopsy rate formed a base for a nationwide analysis of asphyxia homicides (n = 383) during 30 years. The cases were identified through multiple records, and all the forensic pathology case files were studied in detail. ⋯ Every tenth female victim had genital injuries. Toxicological analyses were performed in close to all of the cases, and almost three out of four victims tested positive for blood alcohol. The various aspects of the demographics and autopsy findings covered in this study contribute reliable and accurate data to further strengthen the spectrum of observable medico-legal characteristics of asphyxia homicides.

Sharp force trauma is a common homicide method. The weapon is typically a knife, which is easily accessible and does not require special skills. We have analyzed all 471 sharp force homicides in Denmark during 1992-2016 with special focus on aspects that are relevant to forensic pathologists, including the distribution of wounds and organ injuries. ⋯ The results clearly show strong sex differences in both victims and offenders. This could be useful for shaping policies and public opinion, and as a route for understanding the developments in interpersonal violence. In the narrow setting of death investigation, our results will provide an evidence-based approach to understanding the injury patterns in sharp force homicide.
