The influence of site of collection on postmortem morphine concentrations in heroin overdose victims
Crandall CS Kerrigan S Blau RL Lavalley J Zumwalt R McKinney PE 《Journal of forensic sciences》2006,51(2):413-420
When assaying for postmortem morphine concentration, significant site sampling variability exists between central and peripheral sampling sites and even within sampling regions of the body. To study the variation, 76 suspected heroin overdoses were identified. Each had femoral artery (FA) and vein (FV), left and right ventricle and pooled heart blood samples obtained at autopsy. Forty-four tested positive for morphine. Morphine concentrations were determined by gas chromatography/mass spectrometry, with sampling site differences reported as log-transformed ratios and compared by signed rank test.The mean FA to FV ratio for total morphine was 1.2 (range 0-4.5). The ratio for left heart to right heart total morphine was 1.1 (range 0.4-3.2). Left ventricular to FV total morphine ratio was 2.0 (range 0.6-6.9). In these opioid overdose deaths, FA and FV morphine concentrations are usually similar, although up to 4.5-fold differences were noted. Centrally obtained morphine concentrations are on average twice as high compared with peripheral morphine concentrations. Left and right ventricular morphine concentrations were usually similar, although up to 3.2-fold differences were noted (left side higher). 相似文献

In the English literature, facial approximation methods have been commonly classified into three types: "Russian,"American," or "Combination." These categorizations are based on the protocols used, for example, whether methods use average soft-tissue depths (American methods) or require face muscle construction (Russian methods). However, literature searches outside the usual realm of English publications reveal key papers that demonstrate that the Russian category above has been founded on distorted views. In reality, Russian methods are based on limited face muscle construction, with heavy reliance on modified average soft-tissue depths. A closer inspection of the American method also reveals inconsistencies with the recognized classification scheme. This investigation thus demonstrates that all major methods of facial approximation depend on both face anatomy and average soft-tissue depths, rendering common method classification schemes redundant. The best way forward appears to be for practitioners to describe the methods they use (including the weight each one gives to average soft-tissue depths and deep face tissue construction) without placing them in any categorical classificatory group or giving them an ambiguous name. The state of this situation may need to be reviewed in the future in light of new research results and paradigms. 相似文献

The use of oligonucleotide fingerprinting is evaluated in practical forensic work, using both artificially and systematically produced stains as well as actual case work material. The probes (CAC5/(GTG)5 are superior because of their individualizing potential in comparatively fresh specimens with little DNA degradation, whereas (GACA)4, still produces substantial information when high molecular weight DNA is lacking. The overall limitations and the advantages of this technology are discussed in detail and compared to the classical minisatellite probes. 相似文献

While teachers and students of law tend to take for granted that critical legal campaigning originates in the late 20th century, many historians suggest that the summons of law and its state of accusation before the tribunal of critique dates back to the days of the Enlightenment. I am arguing, in contrast, that, in the West, the history of legal critique is by no means shorter than the history of law; that Western legal evolution embraces and supposes anti-legalism or ‘antinomianism’ since the days of early Christianity and throughout; that, conversely, an adequate assessment of Christianity must stress its character as an anti-institutional, anti-legal, and anti-religious campaign; that the standard view of Humanism, Enlightenment, and Modernity, which tends to foreground their antagonism to Christian institutions and to deny their nature as instantiations of the Christian campaign, misses the crucial point both about them and about Christianity (and, implicitly at least, about geopolitics); that key concepts of political modernity thrust their roots, not only and not most importantly into Political Theology, but rather into Saint Paul’s legal ‘new deal’; that, far from giving rise, as intended, to a deactivation of law, Paul’s action has resulted, instead, in the interlinking build-up of a militant denial of law on the one hand, and an emerging intensification of law on the other hand. Let the reader be warned that the article strings together a bouquet of snap-shots from a work in progress. 相似文献

Occupational accidents, often presenting with lethal outcomes, are a rarely reported issue in forensic literature. However, these incidents are part of medicolegal casework with special regard to reconstruction, liabilities and insurance law-related issues, respectively. We report on a lethal occupational accident in a metropolitan sewage plant. When performing routine controls, a technician fell into an overflow sewer and was immediately pulled into a 30 cm diameter drain. Rescue efforts were initiated immediately, but had to be terminated due to gas warning. Rescue teams continued the search, however, the body remained undiscoverable. Forty-eight hours later, the cadaver was found in an adjacent digester tank, from where it was finally rescued. It was concluded, that the body had been transported between the overflow sewer and the digester tank through a 120 m pipeline with several 90 degrees bendings and branch connections with a minimum diameter of 25 cm at the discharge valve. On medicolegal examination, the cadaver showed marked signs of advanced decomposition caused by anaerobic microorganisms in the 37 degrees C biomass environment. Moreover, as a consequence of the passage of the pipeline system, signs of massive trauma (several comminuted and compound fractures) were disclosed at autopsy. To us, this is the first report on a lethal occupational accident in a sewage plant; our observations demonstrate the rapid progress of putrefaction in a warm anaerobic bacterial environment and the massive trauma sustained. 相似文献

Conjunctival petechiae from 15 cases (cause of death: different natural and unnatural) were analysed using confocal laser scanning microscopy (CLSM) in order to visualize the kind of the damage within the vessel wall (diapedesis versus rhexis). The pathomorphological findings with multiple ruptures of vessels appearing to be filled to bursting point define the conjunctival petechiae as a rhexis-haemorrhage. 相似文献

Death due to neurogenic shock following gastric rupture in an anorexia nervosa patient 总被引:2,自引:0,他引:2
We report a case of fatal gastric rupture discovered after death, which developed due to a bulimic attack of a 19-year-old woman suffering from anorexia nervosa. An autopsy revealed an acute gastric dilatation and rupture without commonly observed ischemic damage of gastric wall structures. However, it may be difficult to determine the cause of death despite the marked findings. The death as a consequence of neurogenic shock accounts for all the results of gross examination and histologic analysis. This case is the first reported case of fatal gastric rupture of an anorectic patient discovered after death. 相似文献
