Mnemic disturbances occurred in 8 of 14 subjects during a pharmcopsychological investigation of possible interactions between alcohol and dipotassium chlorazepate (Tranxilium). The blood alcohol concentrations were between 0.87% and 1.32%; the serum concentrations of the active metabolite nordiazepam were in the therapeutic range between 145 ng/ml and 345 ng/ml. The constitutional, dispositional, and situative conditions are presented. The forensic medical interpretation of such mnemic disturbances must be made critically and with reservation when evaluating a psychopathological state. 相似文献

During the 1970s the share of health care expenditure in Canadian GNP remained roughly stable, in the range of 7-71/2 percent of GNP, in marked contrast to its escalation in most other countries (the U.S. in particular) and to previous Canadian experience. The shift to a stable pattern coincided with the completion of the Canadian system of universal comprehensive public hospital and medical care insurance. This paper explores how and why the public insurance system served to contain cost escalation. It then discusses the inadequacy of expenditure experience per se as a basis for health system evaluation--the same data will support claims of both "underfunding" and "spiralling costs." More serious questions involve the influence of alternative patterns of health care funding and delivery on the effectiveness and efficiency of care provision, and the resulting distributional patterns of care and income. A brief sketch is given of the present situation and future possibilities of Canadian health care under these heads. 相似文献

In the article Mr. Smith considers the need for reform in the area of defining when death occurs and the various approaches that exist to define death. He then analyses the stages of the developments in the various Australian jurisdictions and discusses the substantive content of the basic definition adopted and the practical implications of any enactment. The author suggests that the concept of death should be legislatively enacted in relevant pieces of legislation which call for a resolution of the question at the present time and a more general separate statement defining death should be avoided at the moment. Conceptually death should be defined as the permanent and irreversible loss of consciousness of the individual as determined by irreversible cessation of the brain stem function. The actual operational criteria of death should form the subject of a circular published by the relevant statutory health authority for the guidance of medical practitioners in relation to the specific problems they face. 相似文献
