Organ procurement and transplantation have grown steadily, and the need for organs will only rise in the future. Increasing the number of potential donors is therefore paramount. However, transplant coordination teams face refusals that can be linked to the contexts of the deaths, especially when they involve legal issues. In France, deaths involving legal proceedings are not uncommon (7-10%). In these cases, the prosecutor is immediately contacted, and makes the decision of whether to remove the involved organs. Refusals of this type represent 4% (approximately 30 cases per year) of obstacles to organ removals, and are governed by specific legislation. Thus, the prosecutor must arrange contact with a forensic pathologist and with the organ transplant teams to assemble all of the necessary elements for him to take the decision. To assist prosecutors in their decision making and to ensure them scientific rigour, the French Society of Forensic Medicine sought to develop a national recommendation to harmonise practices; it emerged in early 2013. The guideline makes practical recommendations, including among others: nominating local referents; writing regional protocols between judicial authorities, forensic pathologists and transplant teams; establishing terms for the forensic pathologist's intervention on the donor's body before and after a procurement. This recommendation by the French Society of Forensic Medicine aimed to combine two interests: addressing the shortage of organs, and fulfilling the requisites of a criminal investigation by standardising practices and encouraging communication., (© The Author(s) 2014.)

Terrorist attacks have been on the rise. During the recent terrorist attacks in France, terrorists perpetrated their acts using weapons of war, as well as explosive charges. These two modes of action, when combined, can create skin lesions with similar macroscopic appearances, which can sometimes go unnoticed because of body fragmentation. A total of 68 autopsies, 83 external examinations, 140 standard radiographic examinations, and 49 computed tomography (CT) scans were performed over 7 days during the 2015 terrorist attacks in France. Bodies were injured by firearms and shrapnel-like projectiles. We analysed the clinical findings for the secondary blast cutaneous lesions from the explosive devices and compared these lesions with ballistic-related lesions to highlight that patterns can be macroscopically similar on external examination. Secondary blast injuries are characterised by penetrating trauma associated with materials added to explosive systems that are propelled by explosive air movement. These injuries are caused most often by small, shrapnel-like metallic objects, such as nails and bolts. Propulsion causes ballistic-type injuries that must be recognised and distinguished from those caused by firearm projectiles. Differentiating between these lesions is very difficult when using conventional criteria (size, shape, number and distribution on the body) with only external examination of corpses. This is why the particularities of these lesions must be further illustrated and then confirmed by complete autopsies and radiological and anatomopathological examinations. When occurring simultaneously in terrorist attacks, injuries caused by secondary blasts appear as cutaneous wound patterns that can be macroscopically very similar to those caused by firearm projectiles. The criteria usually found in the literature for distinguishing these two types of projectiles may be difficult to use. It is important in these difficult situations to benefit from systematic postmortem imaging. Systematic autopsy and then anatomopathological analyses of the orifices also help determine the cause of the wounds. [ABSTRACT FROM AUTHOR]

The terrorist attacks of November 2015 led to the immediate death of 129 victims admitted to the Legal and Forensic Medicine Institute of Paris, including 41 unidentified. During the Disaster Victim Identification (DVI) operations, 22 bodies were examined by the postmortem (PM) dental team with the aim of establishing PM odontograms. At the same time, the dental expert in the antemortem (AM) unit collected a large number of dental files, progressively filtered as the list of missing persons became reduced. Feedback from these events has highlighted the difficulties of implementing the DVI chain principles in a legal framework, published the day before the attacks, and also the technical complexity of collecting dental data on a week end of terror. The return on experience after this event has represented a paradigm shift on previous methods of DVI in Paris and even more in France. Indeed, the victim identification procedure was redesigned, integrating new technical means such as a CT scan directly on spot, allowing the extraction of maxillofacial data as soon as possible in order to support the PM dental examination team. Moreover, the National Dental Council proceeded to the overall remodeling of the dental identification unit, which is composed of trained members, from local, regional and national aspects. These forensic experts are dedicated, at the request of the legal authorities, to DVI operations and deployed throughout the country capable of managing AM and PM data. This unit aims also to share experiences and awareness-raising among health professionals and investigators in order to optimize a better submission of AM elements and also to enhance the major interest of odontology as a primary identifier in disaster.

In cases of terrorist bomb attacks, the issue of victim identification is the principal aim. For investigators and justice, terrorists must also be identified in a timely manner. The fragmentation of bodies caused by explosive devices however makes this operation difficult. The cases presented correspond to six autopsies of perpetrators carrying explosives. Their explosive belts produced different body sections on areas correlated with the location on the body of carrying explosive charges. Indeed, cross-sectional areas are the signature of the level of explosive devices on the body, and some fracture features through the damage of certain areas of constitutional weaknesses are specific elements to consider. These elements can allow a quick distinction between victims and terrorists, in order to assist in the medico-legal process of identification. [ABSTRACT FROM AUTHOR]

The article about the "Overview of clinical forensic services in various countries of European Union" [[1]] is an important milestone in the field of clinical forensic medicine in so far that one of the main proposals would be to set up a Clinical Forensic Network for Europe. Were to discuss a future Clinical Forensic Network for Europe (CFN Europe) and a European-wide minimum standard for clinical forensic examinations. Furthermore, the CFN Europe could be a network proposing training for medical staff and other occupational groups who are in close contact with victims of physical and/or sexual violence in order to secure and adequately store forensic findings.

• The protective shell around the otic capsule preserves it from degradation. • The absence of vascularisation prevents exogenous contamination in petrous bones. • Degradation in petrous bones varies depending on environmental factors. • STR genotyping is more reliable using DNA extracted from petrous bones. Over the last few years, palaeogenomic studies of the petrous bone (the densest part of the temporal bone) have shown that it is a source of DNA in both larger quantities and of better quality than other bones. This dense bone around the otic capsule has therefore been called the choice substrate in palaeogenomics. Because the practice of forensic genetics responds to different imperatives, we implemented a study aimed at (i) understanding how and why the petrous bone is an advantageous substrate in ancient DNA studies and (ii) establishing whether it is advantageous in forensic STR typing. We selected 50 individual skeletal remains and extracted DNA from one tooth and one petrous bone from each. We then amplified 24 STR markers commonly used in forensic identification and compared the quality of that amplification using the RFU intensities of the signal as read on the STR profiles. We also performed histological analyses to compare (i) the microscopic structure of a petrous bone and of a tooth and (ii) the microscopic structure of fresh petrous bone and of an archaeological or forensic sample. We show that the RFU intensities read on STR profiles are systematically higher in experiments using DNA extracted from petrous bones rather than teeth. For this reason, we were more likely to obtain a complete STR profile from petrous bone material, increasing the chance of identification in a forensic setting. Histological analyses revealed peculiar microstructural characteristics (tissue organization), unique to the petrous bone, that might explain the good preservation of DNA in that substrate. Therefore, it appears that despite the necessity of analysing longer fragments in forensic STR typing compared to NGS palaeogenomics, the use of petrous bones in forensic genetics could prove valuable, especially in cases involving infants, toothless individuals or very degraded skeletal remains.
