Despite the fact that brain arteriovenous malformations (BAVMs) are a possible cause of sudden and unexplained death, very few papers have discussed their importance in the forensic context. BAVMs consist of tangled masses of tortuous arteries and veins devoid of intervening capillaries that frequently extend from brain parenchyma into the subarachnoid space. Apart from BAVMs, three major groups of vascular malformations of the brain are known: cavernous hemangioma, venous angioma, and capillary telangiectasia. BAVMs and cavernous hemangioma often cause hemorrhages, while venous angioma and capillary telangiectasia are typically asymptomatic. Presented here is the case of a 14-year-old girl who died from a ruptured BAVM. The present case is a reminder that the forensic pathologist should be able to recognize BAVMs and to differentiate it from other types of vascular malformations. Although rare, it is a cause of sudden death not to be overlooked, especially in children.

The pathological diagnosis and proof of asbestos causation in environmental-occupational diseases is based on a spectrum of increasingly sophisticated determinations with greater confidence in detection of asbestos bodies and fibers. These include the following: pathology (histology) and/or thick smears of lung, microincineration, bulk chemical digestion, and electron beam instruments. The requisites of medical and forensic asbestos causation differ, and do not always require the full range of these analytical techniques. The need and significance of some of these determinations, as expressed in number of asbestos bodies and fibers, may be related in many cases to the evidence of asbestosis; to the gross and microscopic pathological findings (asbestosis, lung carcinoma, mesothelioma); the exposure history (type, duration, intensity, and period of latency); and nature of the asbestos mineral. An algorithm for the forensic pathological diagnosis of asbestosis and of asbestos-related diseases is proposed.

At the Annual Meeting of the National Association of Medical Examiners in Chicago, Illinois, in November 1981, Dr. W. Sturner, Chief Medical Examiner of the State of Rhode Island, gave his perspectives as far as clinical forensic medicine and pathology are concerned. This topic, therefore, brought to mind the idea of writing an analysis of the medicolegal system in Greece. This article attempts to show the advantages, problems, and the perspectives of an old-style medicolegal investigation system, existing in Greece since 1910. The clinical aspects of forensic medicine and pathology is exemplified by the presentation of the preliminary results of the study of injuries in traffic accident victims, 1,600 cases examined by the author with the support of other colleagues in Athens, Greece.
