What is the best sample for determining the early postmortem period by on-the-spot flow cytometry analysis?

The level of degradation of DNA as a means for determining the time of death has been proposed as a valid adjunct to the classic thanatochronologic methods. The twofold aim of this work was to determine which organ might reveal both a correlation between the percentage of degradation of the DNA and the time lapse since death, and would be easiest to sample and yield the most reproducible results even in technically unfavorable situations such as on-the-spot investigations at the scene of death. A comparison of the spleen, blood, and liver showed that hepatic tissue best meets these specific needs because it shows a virtually linear correlation between the time elapsed since death and the level of degradation of the DNA, and it can easily be sampled at the scene of death by use of a common biopsy needle.     

Bile analysis of drugs in postmortem cases

Bile is, in certain cases, collected together with blood from different sites (heart, brain, femoral), urine and other organs or matrices. This study reports comparative results obtained from the analysis of blood and bile for different drugs found: acetaminophen, amphetamine and related compounds, several antidepressants, several benzodiazepines, cocaine and its metabolites, dextropropoxyphene and its metabolite, hydroxyzine, methadone and metabolite, morphine and codeine, levomepromazine, thioridazine, propranolol, tramadol and its metabolite. Several findings are presented: (1) There were no significant differences in the levels of the compounds among the samples of blood obtained from different sites. (2) Levels in bile are generally several fold higher than those in blood. The mean bile to blood ratios vary from about 1 (for acetaminophen, amphetamine) to about 2000 (for desmethylclobazam). (3) In certain cases (16 over 44), although the drug or its metabolite was not detected in blood from different sites, it was detected in bile. As other authors had advocated, it is very useful to ask the pathologist to take the gall bladder with its contents together with the other samples, in order that the sample of bile can be used in the comprehensive toxicological analysis and therefore be complementary to the other fluids or matrices. An additional advantage for using bile is that the concentrations of drugs or their metabolites are generally several fold higher than their blood concentrations.     

欧盟宪法危机的成因、影响及出路

欧洲迎来了历史上前所未有的和平统一的机会,欧元的成功已进一步地把欧洲的经济融合到一起。政治上,欧盟宪法的起草也给人们以巨大的希望,人们希望看到一个统一、和平的欧洲出现。但在2005年,法国和荷兰先后在全民公决中,否定了《欧盟宪法》,这给欧洲统一的进程蒙上了阴影。本文尝试分析此次危机出现的原因,并进一步探讨危机出现可能带来的影响,以及预测今后欧洲一体化的前景。

Mitochondrial DNA error prophylaxis: assessing the causes of errors in the GEP'02-03 proficiency testing trial

A qualitative and quantitative analytical method was developed and validated for the determination of 49 licit and illicit drugs in oral fluid. Small oral fluid samples, volume 1mL, were collected from volunteers using a modified Omni-Sal device and the analytes were extracted from an oral fluid/buffer mixture using a single Bond Elut Certify solid phase extraction cartridge. Liquid chromatography-tandem mass spectrometry (LC-MS-MS) and gas chromatography-repetitive full scan mass spectrometry (GC-MS) were used in parallel to analyze the extracts for the targeted drugs. Extracts were analyzed by GC-MS in their underivatized form and as their pentafluoropropionyl derivatives. Deuterated internal standards were used for quantification of drugs of abuse by LC-MS-MS to minimize matrix effects. Methadone-d(9) and tumoxetine were used as the internal standards for quantification of non-derivatized and derivatized analytes respectively by GC-MS. Linearity was demonstrated over the range 5-200 ng/mL and limits of detection were less than 4 ng/mL for each drug analyzed. The method demonstrated acceptable recoveries for most of the analytes and good intra- and inter-day precision. Acquisition of data by repetitive full scan GC-MS allows the addition of further analytes to the target menu.     

Y-chromosomal STR haplotypes in a population sample from continental Greece, and the islands of Crete and Chios

Eight Y chromosome short tandem repeat (STR) polymorphisms (DYS19, DYS385, DYS389I, DYS389II, DYS390, DYS391, DYS392, and DYS393) were analyzed in the sample of 117 unrelated Albanian males living in Kosovo. A general STR allelic frequency pattern in the Albanian population from Kosovo corresponds to other European populations. Fourty six haplotypes were observed in single copy. The most frequent haplotypes were (DYS19-DYS385-DYS389I-DYS389II-DYS390-DYS391-DYS392-DYS393) 14-11/11-13-29-24-11-13-13 (10.26%), 14-14/17-12-28-24-10-11-12 (9.40%), 13-16/18-13-30-24-10-11-13 (9.40%), and 14-17/17-13-31-24-10-11-13 (9.40%).     

Suicide with a butcher's bolt

The captive bolt pistol is an atypical firearm exclusively produced and used for butchery of breeding animals, but in some rare cases, it has been used as a lethal weapon for committing suicide by butchers, breeders and other people who have access to such weapons during their professional activities. This study describes the suicide committed by a butcher in the province of Udine (N. Italy) in 2001 who shot himself with his own captive bolt pistol that produced in the right temporal region a circular wound and a bone lesion of the temporal squama with a groove involving the frontal lobe; he died five days later of the fatal consequences of the meningo-encephalic lesions. The medico-legal issues implicated in this case, seen in the light of the data reported in the international literature, illustrate the difficulties faced when diagnosing these types of lesions, bearing in mind their rarity and peculiar nature, and introduce elements of differential diagnosis regarding lesions produced by similar weapons that lead to ascertainment of the event as accidental, suicidal, or homicidal.     

Medical malpractice: a study of case histories by the Forensic Medicine Section of Bari

The learning objectives of this paper are to study the actual extent of medical malpractice, the medical acts at risk, and their impact on mortality. The number of suits filed against physicians for deaths resulting from alleged malpractice and autopsies ordered by the Judicial Authority in cases of possible therapeutic misadventures are rising. A major factor pushing this trend is public mistrust of healthcare providers and public and facilities. This mistrust is partly fueled by the mass media which, often to gain larger audience shares, sensationalizes single cases of real or alleged iatrogenic injury. Further, the potential for astronomic settlements, either from the single doctor or from the healthcare institution, has increased the number of legal proceedings that start on the basis of mere suspicion. In this context, the autopsy becomes an important instrument for shedding light on the situation, and it must be carried out by highly qualified and experienced professionals capable of ascertaining the cause of death, identifying any possible misconduct, and assessing its consequences. We reviewed the data regarding autopsies performed at the Forensic Medicine Section of the Department of Internal and Public Medicine of the University of Bari over 1991 to 2000. We culled the cases alleged malpractice and, from these, identified those in which the death had truly been caused by medical error. This study also allowed us to understand the incidence of lethal therapeutic misadventures and to identify the medical and surgical branches more frequently involved.
