Audit in forensic pathology

Autopsy numbers in Australian hospitals have declined markedly during the past decade despite evidence of a relatively static rate of demonstrable clinical misdiagnosis during this time. The reason for this decrease in autopsy numbers is multifactorial and may include a general lack of clinical and pathologic interest in the autopsy with a possible decline in autopsy standard, a lack of clinicopathologic correlation after autopsies, and an increased emphasis on surgical biopsy reporting within hospital pathology departments. Although forensic autopsies are currently maintaining their numbers, it is incumbent on forensic pathologists to demonstrate the wealth of important information a carefully performed postmortem examination can reveal. To this end, the Pathology Division of the Victorian Institute of Forensic Medicine has instituted a program of minimum standards in varied types of coroner cases and commenced a system of internal and external audit. The minimum standard for a routine, sudden, presumed natural death is presented and the audit system is discussed.     

Computer forensic timeline visualization tool

Computer Forensics is mainly about investigating crime where computers have been involved. There are many tools available to aid the investigator with this task. We have created a prototype of a new type of tool called CyberForensic TimeLab where all evidence is indexed by their time variables and plotted on a timeline. We believed that this way of visualizing the evidence allows the investigators to find coherent evidence faster and more intuitively. We have performed a user test where a group of people has evaluated our prototype tool against a modern commercial computer forensic tool and the results of this preliminary test are very promising. The results show that users completed the task in shorter time, with greater accuracy and with less errors using CyberForensic TimeLab. The subjects also experienced that the prototype were more intuitive to use and that it allowed them to easier locate evidence that was coherent in time.     

Computer-assisted systems for forensic pathology and forensic toxicology

A computer software, R?ttsBASE (RB), was developed for all forensic pathology units in Sweden and introduced in 1992. Simultaneously, a corresponding software, ToxBASE (TB), was developed for the Department of Forensic Toxicology, where all forensic toxicology in Sweden is managed. Both of the databases were created using dBASE IV, and the programming was carried out according to specifications from the staff at the forensic toxicology and forensic pathology units. since the development or RB and TB was coordinated, the systems can run together smoothly. The purpose of both systems was to automate the offices and to enable compilation of detailed statistics. Installation of Novell Netware and ISDN-connections (Integrated Service Digital Network) has enabled rapid communication between the units and easy compilation of nationwide statistics of forensic pathology and forensic toxicology. the systems offer a wide spectrum of reports and include a simple module for evaluation of the importance of the forensic efforts for th whole death investigation. The configuration of the softwares has also enabled processing of a large amount of related toxicological and autopsy data that in turn has yielded a base for compilation of toxicology interpretation lists. This article includes a summary of the features of the software and a discussion of its benefits and limitations.     

The forensic pathology specialty certifications

The subspecialty of pathology known as forensic pathology has been certified by the American Board of Pathology since 1959, when the first examinations were offered in New Orleans, Louisiana, U.S.A. This article provides information on those who have been certified since 1959 and also the requirements for this certification by the American Board of Pathology.     

Cardiac pathology in 470 consecutive forensic autopsies

Cardiovascular disease continues to be the single most common generic cause of sudden and unexpected deaths. Atherosclerotic coronary heart disease and acute myocardial infarction are the most prevalent forms of fatal cardiac disease observed at autopsy. Other cardiac lesions are frequently listed as causes of death, but the prevalence of such lesions as incidental findings in the general population is unknown. In this study, 470 consecutive forensic autopsies were evaluated for minor and major anomalies. The most frequently observed major congenital finding was floppy mitral valve (5%). Tunneled coronary arteries, considered minor congenital findings, were seen in 29%. Atherosclerotic coronary heart disease was the most common major acquired finding, observed in 16% of cases. Of the 470 hearts, only 8% were considered normal.     

Introduction to the forensic pathology of cocaine.

During the last several years, a clearer understanding of cocaine's effects on the body has emerged. Metabolism and tissue distribution are better understood. A diverse group of cocaine-related illnesses have been reported, but many appear to share the underlying mechanism of catecholamine toxicity. Knowledge of cocaine's metabolism makes possible certain conclusions about route of ingestion, time of use, and patterns of abuse in general. Knowledge of the histologic alterations known to be associated with cocaine use can pinpoint cocaine as the cause of death, even in cases where there are negligible blood levels. What follows is a brief review of recent observations that bear on the forensic aspects of cocaine abuse.     

虚拟现实技术在法医病理学中的应用

对虚拟现实技术的概况及其在法医病理中的运用、发展前景进行了综述。文献资料表明:随着手术导航系统、虚拟尸检、显微影像技术等虚拟现实技术的产生发展,这必将对法医病理学的教学、实验、科研及其实际运用产生深远的影响,并将极大推动本学科的发展。但由于软硬条件、成本、费用等的限制,这一技术要真正进入实践运用还需要进一步改进、完善。

A second generation computer forensic analysis system

The architecture of existing – first generation – computer forensic tools, including the widely used EnCase and FTK products, is rapidly becoming outdated. Tools are not keeping pace with increased complexity and data volumes of modern investigations. This paper discuses the limitations of first generation computer forensic tools. Several metrics for measuring the efficacy and performance of computer forensic tools are introduced. A set of requirements for second generation tools are proposed. A high-level design for a (work in progress) second generation computer forensic analysis system is presented.     

The legal aspects of corporate computer forensic investigations

The use of computer forensics was previously limited mainly to law enforcement agencies. However, UK organisations are increasingly undertaking computer forensics activities for incidents such as fraud, money laundering, accessing or distributing indecent images, harassment, industrial spying and identity theft amongst others. In this paper we examine the legal aspects of UK corporate computer forensic investigations.     

Microwave processing and ethanol-based fixation in forensic pathology

An ethanol-based fixative (FineFIX) has been used, together with rapid microwave-stimulated processing, in postmortem material, resulting in a rapid fixation and processing of the tissues with morphology, histochemical stains, and immunocytochemistry comparable to formalin-fixed material. Furthermore, this alternative fixation gives better DNA recovery in higher amounts if compared with DNA extracted from formalin-fixed tissue, particularly advantageous in forensic pathology.     

Killing a wolf--an unusual case of forensic veterinary pathology

During a hunt in Western Pomerania in January 1999 a wolf, injured at the left hind leg, was killed by a shot in the chest region. It was a 2-year-old male that probably came to Germany from Poland by crossing the Oder River. The hunter was reported to the police afterwards, because there were doubts as to the legality of the lethal shot. The hunter pleaded relief by reason of section 22 a German Hunting Law (prevention of avoidable pain or suffering of wild animals). After the shooting there was a number of wrong expert statements by a veterinarian and two zoologists concerning the age of the injury on the left hind leg and the direction of the shot to the chest region, which were corrected by subsequent medico-legal examinations performed on the order of the prosecution.
