AIDS and infection control in forensic investigation 总被引:1,自引:0,他引:1
Infection control in the workplace is becoming an increasingly important issue, not only for health care workers, but also for any workers who could potentially be exposed to infectious material. We discuss the nature, modes of transmission, and infectivity of important infectious agents likely to be encountered in the course of forensic investigations. We provide principles and guidelines for appropriate procedures and practices to be followed in a program of infection control. 相似文献

The review of 32 deaths resulting from hypothermia yielded mostly the common pathological findings as bright red livores, haemolytic frost marks of the skin and Wichnewski erosions of the gastric mucosa. In addition the muscle system of the body core (musc. ileopsoas) showed hemorrhages and histologically necrosis of its fibres in form of segmental and discoid sarcoplasmatic alteration. These changes are a quite specific sign of death due to hypothermia, as far as mechanical injury can be excluded. For best result however a special autopsy technique and an appropriate histological staining are advisable. 相似文献

The Lewis blood grouping of human saliva stains could be detected by an enzyme-linked immunosorbent assay (ELISA) using anti-Le(a) and anti-Le(b) monoclonal antibodies with an avidin-biotin complex (ABC). The saliva stains (1.0 by 1.0 cm in size) were used as samples and not only could the Lewis substances of 57 individual stains be correctly typed by this method, but also it was clarified that there are several different secretion patterns of amounts of Le(a) and Le(b) substances in 3 individual Lewis types. 相似文献

Experiments were carried out on 30 dogs to investigate the course of respiration during obstructive asphyxia. They were asphyxiated by occlusion of the exposed trachea. Intrathoracic pressure, blood pressure in the femoral artery, electrocardiogram and electroencephalogram readings were registered. In most cases, the respiration course during the dyspnea stage by occlusion of the trachea generally had an inspiratory character. In a few animals, when the trachea was occluded in the expiratory phase, there were a few positive expiratory respirations with moderate inspiratory movement and thereafter the respirations were inspiratory during the dyspnea stage. The terminal respirations, which occurred 1-2 min before the circulatory breakdown, were generally inspiratory, but in a few dogs they were expiratory. 相似文献

A group of five hyperthermia-related deaths is presented in which urinary noradrenaline (NA) concentrations were elevated (172.1 +/- 119.4 ng/ml) compared with a control group of rapid violent deaths (43.7 +/- 26.1 ng/ml). Urinary adrenaline (A) concentrations were not elevated in the hyperthermia cases, nor were there any significant differences in urinary dopamine (DA) concentrations between the two groups. All except one of the hyperthermia victims were under the influence of ethanol. It is suggested that a combination of heat stress and ethanol consumption was responsible for the elevated urinary NA in the hyperthermia cases, reflecting increased sympathetic nervous system activity. A combination of high urinary NA with low A seems to be characteristic of hyperthermia fatalities, in contrast to hypothermia deaths, where both NA and A are usually elevated. 相似文献

A report is made of a 44-year-old female who died of malignant hyperthermia during general anesthesia for an operation of left subtrochanteric femoral fracture. Symptoms began with increases in heart rate and blood pressure after the introduction of anesthesia with halothane and were accelerated by the administration of succinylcholine, followed by muscle rigidity and high temperature. The typical wine red urine was observed. The oral temperature of 42 degrees C was recorded within 1 h after succinylcholine. The rectal temperature was 30 degrees C 22 h after death. Severe pulmonary edema and tubular necrosis of the kidney were found by postmortem examination. No latent myopathy was observed. The creatine phosphokinase levels in plasma obtained after the onset of malignant hyperthermia and at the time of autopsy were abnormally high and were 5632 and 34,854 mU/ml, respectively. Plasma myoglobin levels were 130,000 and 2.8 X 10(6) ng/ml, respectively. 相似文献

Nonprofit and for-profit medical care: shifting roles and implications for health policy 总被引:4,自引:0,他引:4
The contemporary expansion of investor-owned health care facilities has stimulated much controversy but little response from policymakers. We believe this results from the apparently ambiguous relationship between ownership and socially valued outcomes. In our assessment, this ambiguity occurs largely because the effects of ownership are mediated in complex ways by characteristics of the services being delivered and the training of health care providers. Reviewing both the history and current performance of nonprofit and for-profit health care facilities, we identify some of the more important of these mediating factors. Taking these into account, there is a consistent influence of ownership on the delivery of health services. On the basis of this analysis, we discuss appropriate policy responses to the future growth of investor-owned health care organizations. 相似文献
