Homicide by stab wound is common worldwide. However, the use of unusual edged weapons is rarely reported in the forensic literature. Here, we report two cases of homicide involving a Japanese sword, or katana, and a sickle. Both of these weapons can create either stab or incised wounds with some particularities. In our cases, characteristics of the external wounds, internal injuries, and the depth of penetration raised the possibility of an unusual weapon. Meticulous forensic examination of these injuries (morphological characteristics, depth of penetration, trajectories, and cut marks in the bone) may allow the forensic expert to determine the type of weapon used.

Hyperostosis frontalis interna is a common phenomenon, which may have been overrated in its significance in the past, and may, currently be underrated in its significance. We present three cases of hyperostosis frontalis interna found during medicolegal autopsies and discuss their forensic considerations. The patients were all middle‐aged women with metabolic and endocrine manifestations and psychiatric ailments; thickening of the inner table of the frontal bone of the skull was found during each autopsy. We describe the relationship between hyperostosis frontalis interna, metabolic manifestations, and neuropsychiatric symptoms as part of Morgagni‐Stewart‐Morel syndrome. There is still considerable disagreement in the scientific community as to whether this syndrome is a clinical entity. Nonetheless, awareness of Morgagni‐Stewart‐Morel syndrome can be of help in understanding the circumstances surrounding death. In some other cases, hyperostosis frontalis interna could be used by forensic pathologists as criteria for sexing and aging a skeleton. [ABSTRACT FROM AUTHOR]

We report the case of a middle-aged man, without medical history, who suddenly died at his workplace. The autopsy highlighted a pathological heart macroscopically, with multiple small white areas on the left myocardium. Coronary dissection revealed a pseudotumoural fibromyxoid aspect within the anterior interventricular artery (AIVA) and the left main coronary trunk, including reduction in their diameter with tight stenosis. Microscopic examination of these arteries showed fibroinflammatory wall destruction. In the left myocardium, there were multiple focal ischemic areas at different stages of recovery. Our case is an illustration of primary ischemic heart disease due to coronary arteritis, with a pseudotumoural presentation, which was revealed by sudden death. We discuss the cause of death and the etiological diagnosis preceding coronary arteritis. [ABSTRACT FROM AUTHOR]

The authors present a case of takotsubo cardiomyopathy ( TTC) following physical assault. In France, public prosecutor orders a medicolegal assessment after an assault for all living victims. Medicolegal assessment aims to establish a causal relation between an aggression and the injury sustained. An 80-year-old jeweler was the victim of assault, restraint and confinement during the hold-up of his jewelry store. After the event, he experienced constrictive chest pain with a sensation of oppression. Transthoracic echography showed apical and middle wall akinesis with apical ballooning pattern. In this case, the experts reasonably accepted that there was a direct, certain, and exclusive causal relation between the aggression and the cardiomyopathy. Forensic specialists should be aware of TTC because it is a frequent complication of stress situations and its incidence in forensic cases is probably underestimated. [ABSTRACT FROM AUTHOR]

A response from the authors of the article "Takotsubo cardiomyopathy in a jeweller following a holp-up: Forensic Considerations" in the 2013 issue is presented.
