People die daily in the hospital. Mostly, they die because their illnesses were no longer treatable (natural death). Unfortunately, some people die an unnatural death, in particular, as the result of euthanasia. In contrast to the situation in most countries, in the Netherlands euthanasia is accepted by the courts under strict conditions. It can be very difficult for the legal authorities to establish whether a person has died from natural causes or from suicide, euthanasia, or murder. In addition to the pathologist and the lawyer, the toxicologist also has a number of problems in showing whether euthanasia has been carried out. These can consist of the following analytical problems: (a) interactions--the patients involved have frequently been receiving a large number of toxic and nontoxic drugs simultaneously; (b) identification--not all drugs administered are included in general screening procedures; (c) metabolites--a large number of metabolites may have accumulated toward the end of a long therapeutic regimen; and (d) determination--determination of quaternary muscle relaxants and their various metabolites, as well as other drugs, can be problematic. There are also toxicokinetic problems; because of poor kidney and liver function, low serum albumen, general malaise, and interactions between these factors and other drugs, the kinetics of a given drug can differ from normal. This makes it all the more difficult to determine whether the patient died from an accumulation of medication or from a so-called "euthanetic" drug mixture.(ABSTRACT TRUNCATED AT 250 WORDS)  相似文献

Two infants aged 4 1/2 and 8 months are reported to have been exposed to overheating by an electric blanket and a heating fan in bed for a period of up to approx. 19 hours. Dehydration complicated the effects of overheating. Due to the case history in combination with the autopsy and histological findings as well as the absence of toxicological findings the following diagnosis could be established: "Death from exhaustion as a consequence of long-lasting heat effect and dehydration." The necessity of thorough investigations in causes of death during infancy is shown by means of the two cases above. If possible, the rectal temperature should already be taken by the coroner. The public should get informed about the risks caused by the use of electric cushions, heating fans as well as floorboard heating.  相似文献

Certain Biblical passages if interpreted literally can be understood as advocating the use of corporal punishment in disciplining children. The purpose of this research was to determine if persons affiliated with religious denominations which emphasized a literal belief in the Bible would demonstrate less appropriate attitudes with regard to discipline than their counterparts who were affiliated with religious denominations which do not subscribe to a literal interpretation of the Bible. The sample consisted of 881 persons who were members of denominations classified as literal or nonliteral believers. Statistically significant differences were noted on the Physical Punishment Scale of the Adult Adolescent Parenting Inventory with persons, regardless of gender or their level of education, who were members of churches subscribing to a literal belief in the Bible preferring the use of corporal punishment over alternate methods of discipline as compared to their nonliteral counterparts.  相似文献

The Satisfaction With Life Scale (SWLS) was developed in the United States as a multiitem scale for the overall assessment of life satisfaction as cognitive-judgmental process, rather as a measurement of specific satisfaction areas (e.g., health, energy). The present study attempted to extend the applicability of the SWLS by investigating specific aspects of reliability and validity in a different cultural context (Portugal) with adolescents. In line with previous American findings, reliability figures were found to be favourable. SWLS scores were affected by sex and sociocultural level. In addition, SWLS scores showed to be predictably associated with psychological measures: loneliness, social anxiety, shyness, self- concept, and physical attractiveness. The variables that best predicted satisfaction were overall self-concept, loneliness, and physical attractiveness.Received a Ph.D. in normal and abnormal anthropology from École des Hautes Études en Sciences Sociales (Paris) in 1980 and a Ph.D. in Social Psychology from Faculty of Psychology (Porto) and an Aggregation in Psychology from Faculty of Psychology (Coimbra) in 1990. Research interests include migration and cross-cultural social migration.The author wishes to thank the anonymous reviewers for their helpful comments on an earlier version of this paper.  相似文献
