The fatal rupture of a saccular aneurysm at the junction between the left anterior cerebral artery and anterior communicating artery affected by fibromuscular dysplasia (FMD) is a rare condition. Here is reported the case of a subject involved in a road traffic accident a few minutes before the death, which opened the debate on the real cause of death in a forensic setting. By autopsy, the examination of the brain revealed subarachnoid haemorrhage with flooding of the ventricles due to the breached saccular aneurysm of the junction between the left anterior cerebral artery and anterior communicating artery, in FMD mainly affecting the circle of Willis arteries. A spontaneous aneurysmal rupture was excluded on the basis of probabilistic analysis, in the presence of alternative hypotheses that could explain the facts. The passenger's delayed loss of consciousness may be explained as much by a hypertension-linked rupture of the aneurysm triggered by the emotional stress experienced, as by the traumatic shaking/impact of the aneurysm against the bony skull structures, in a subject predisposed to aneurysm frailty due to FMD. Overall, the concausal role of both the road traffic accident, typified by high kinetic energy, and the presence of a pre-existing aneurysmatic weakness due to FMD is fully recognized. The identification of anatomical variants, jointly with uncommon diseases at the examination of the brain base arteries in any case of isolated basal subarachnoid haemorrhage, may avoid wrong legal consequences even when the cause of death seems to be obviously of simple traumatic origin., (Copyright © 2020 Elsevier B.V.

Objective: To analyze the morphology and depth of stab wounds experimentally produced on human legs amputated for medical reasons using multislice computed tomography (MSCT) and magnetic resonance imaging (MRI) after the instillation of a single contrast medium solution (CMS)., Materials and Methods: For morphological analysis, MSCT and MRI scans were performed before and after the instillation of CMS into the wound cavity. Depth measurements were performed on the sagittal view only after CMS instillation. Subsequently, each wound was dissected using the layer-by-layer technique and the depth was measured by a ruler. One-way between-groups pairwise analysis of variance (ANOVA) and Bland-Altman plot analysis were used for comparing radiological and anatomical measurements., Results: Unenhanced MSCT images did not identify the wound channels, whereas unenhanced MRI evidenced the wound cavity in 50 % of cases. After the instillation of CMS, both MSCT and MRI depicted the wound channel in all the investigated stabbings, although the morphology of the cavity was irregular and did not resemble the shape of the blade. The radiological measurements of the wounds' depth, after the application of CMS, exhibited a high level of agreement (about 95 % at Bland-Altman plot analysis) with the anatomical measurements at dissection. A similar systematic underestimation, however, has been evidenced for MSCT (average 11.4 %; 95 % CI 7-17) and MRI (average 9.6 %; 95 % CI 6-13) data after the instillation of CMS with respect to wound dissection measurements., Conclusion: MSCT and MRI after the instillation of CMS can be used for depicting the morphometric features of stab wounds, although depth measurements are affected by a slight systematic underestimation compared to layer-by-layer dissection.

The manuscript presents the European Guidelines on medico-legal Methods of Ascertainment and Criteria of Evaluation in cases of suspected subjective "Medical Responsibility and/or Liability" developed by an international working group under the patronage of the European Academy of Legal Medicine. It includes a step-by-step illustrated explanation of approved Flow Charts, articulated in 18 sequential steps and comprehensive of both Methods of Ascertainment and Evaluation Criteria.

The European mosaic of socio-cultural, economic and legal realities is reflected in forensic and legal medicine, in which a great variety of operational modes of forensic medical services, organisational systems, structures, functional competences and scientific research strategies can be observed. The present work analyses the European bio-medicolegal scientific output of the last 5.5 years (exact time window, January 1, 2005-June 1, 2010), categorising papers by nationality of the corresponding author and forensic sub-discipline in question, in order to identify the peculiarities of national sub-specialised competences and to build up international research projects. This country-based bibliometric analysis, based on the number of articles and the impact factor produced by each European country, also considering its economic profile (gross domestic product and per capita gross domestic product), highlights the prevailing productive role of Western and Southern Europe (Germany, Great Britain, Italy, Switzerland, Spain and France). Categorising scientific output by forensic sub-discipline and branch, significant in terms of impact factor are contributions from Germany (coming first in Pathology, Toxicology, Genetics, Anthropology and Biological Criminalistics), Great Britain (first in Clinical Forensic Medicine, Malpractice and Invalidity-Social Insurance), Switzerland (first in Criminology), Italy (second in Toxicology, Anthropology and Invalidity-Social Insurance), The Netherlands (third in Clinical Forensic Medicine and Medical Law and Ethics), Spain (third in Genetics, Criminalistics and Invalidity-Social Insurance) and France (third in Toxicology and Malpractice). Interestingly, several countries with low gross domestic product, such as Poland, Turkey and other Eastern European nations, show notable scientific production in specific sub-disciplines such as Pathology, Toxicology and Forensic Genetics, suggesting that fruitful international cooperation could be planned and be of interest to funding sources within the European Community, also taking into account funds reserved for depressed areas undergoing development.

The manuscript presents the International Guidelines developed by the Working Group on Personal Injury and Damage under the patronage of the International Academy of Legal Medicine (IALM) regarding the Methods of Ascertainment of any suspected Whiplash-Associated Disorders (WAD). The document includes a detailed description of the logical and methodological steps of the ascertainment process as well as a synoptic diagram in the form of Flow Chart. [ABSTRACT FROM AUTHOR]
