Propylene glycol (PG), a widely used solvent and lubricant, is thought to have low toxicity when ingested. Three cases were identified where PG, either alone or in combination with other chemical agents, contributed to death. The decedent in whom PG was the sole agent was a 32-year-old schizophrenic man with cardiomegaly and renal impairment. The blood PG concentration was 4410 mg/L at least 9.5 h following ingestion.  相似文献

The recent decline, indeed perhaps dismantling, of managed care is sometimes treated as both consequence and cause of the political reempowerment of medical providers, whose professional dominance managed care had challenged. Drawing evidence from Round III of the Community Tracking Study of the Center for Studying Health System Change, this article reviews the politics of four "arenas" of managed care regulation--prompt payment, mandated benefits, external appeals, and financial solvency--and concludes that the power of providers is contingent on patterns of coalition and conflict that differ across the discrete arenas. The zero-sum connotations of the "de" and "re" empowerment of providers under managed care fail to capture the subtlety of providers' search for fresh cultural, economic, and political resources in shifting policy contexts.  相似文献

Currently in Australia anti-choice protesters' right to freedom of speech and freedom to protest is privileged over a woman's right to privacy and to access a health service safely, free from harassment, intimidation and obstruction. This article considers how this situation is played out daily at one Victorian abortion-providing clinic. The Fertility Control Clinic was thrown into the spotlight after the murder of its security guard by an anti-choice crusader in July 2001. Australian common law appears not to offer women protection from anti-choice protesters. By contrast, United States and Canadian "bubble" legislation sits comfortably with key constitutional rights. It would be a useful development if Australian governments passed legislation to ensure the rights, wellbeing and safety of Australian women accessing health services. Such legislation would be another step away from the misogynistic and androcentric values once central to our legislative framework.  相似文献

If male workers categorize different groups of women coworkers and, subsequently, treat them differently, the experiences of women from one of these groups would not be indicative of the experiences of women from another group. When this different treatment involves hostile environment sexual harassment of one group, but not the other, then the law must recognize the possibility of "selective sexual harassment." Without this understanding of the nuances of the workplace dynamics, a court could mistake the women of the unharassed group as representing "reasonable women" and the women of the harassed group as simply oversensitive. This paper draws on empirical data to demonstrate such a situation and advocates for a version of the "reasonable victim" standard to facilitate a closer analysis of hostile environment sexual harassment suits.  相似文献

An unusual fatality secondary to oxycodone in a child is reported. A 2-year-old female child was conveyed to a local hospital after exhibiting signs of rubbing of the mouth and staggering. A hospital toxicological immunoassay screen for drugs of abuse and tricyclic antidepressants was performed on a urine sample and reported as negative. She was discharged and found unresponsive the next morning. She was conveyed to a second hospital in full cardiopulmonary arrest and despite resuscitative efforts, was pronounced dead upon arrival. An autopsy was performed and postmortem specimens were submitted and screened for drugs using mainly chromatographic techniques. Quantitation was achieved by gas chromatography with nitrogen phosphorus detection. Confirmation was performed by gas chromatography/mass spectrometry. Oxycodone was the only drug detected in the following concentrations: heart blood, 1.36 mg/L; gastric contents, 7.33 mg in 33 mL (222.34 mg/L); liver, 0.2 mg/kg; and urine, 47.23 mg/L (47,230 ng/mL). In addition, immunoassay testing of the urine was positive for the opiate class of drugs. This case report demonstrates an unusual cause of death in a young child with emphasis on potential limitation in hospital urine screening tests and the importance of complete forensic toxicological testing in all child deaths.  相似文献

Pulmonary thromboembolism is an often fatal complication of venous thrombosis. Any component or combination of the components composing Virchow's triad (venostasis, hypercoagulability, and endothelial damage) increases the propensity for a thrombophilic state. Hypercoagulable states may be inherited or acquired. While the etiology in many cases may be evident either on physical examination or on evaluation of the decedent's medical history, this is often not the case. We conducted a retrospective study of cases presenting to the Jefferson County Coroner/Medical Examiner's Office in Birmingham, Alabama, who were given a diagnosis of pulmonary embolism. A search of cases within the past 23 years yielded 81 cases. An underlying cause was determined in 70 cases (86%). The remaining 11 (14%) cases had no identifiable cause. We believe that a number of these cases may represent an underlying thrombophilic disorder. Since these disorders may be of an inherited or acquired nature, the determination of an etiology may be relevant to the decedent's family. Postmortem blood analyses may in selected cases be useful and appropriate for the detection of some of these disorders. However, such analyses are not practical in all cases, with each case having to be evaluated on its own merits.  相似文献

Consistent with previous research, almost half of a sample of 41 pet-owning battered women reported that their partners had threatened or actually harmed their pets, and over a fourth reported that concern for their pets had affected their decisions about leaving or staying with the batterer. Differences between rural and urban women were not significant, although higher proportions of rural than urban women reported that their partners had threatened or harmed their pets and that concern for their pets had affected their decisions. For the sample as a whole, logistic regression analyses showed that women whose pets had been threatened or harmed were significantly more likely to report that concern for their pets had affected their decisions about leaving or staying. The findings suggest that service providers should inquire about battered women's concern for their pets and should include arrangements for animals in safety planning.  相似文献

Medical staff attorney Snelson answers the Colloquium's charge, "What exactly has to change in the hospital-medical staff relationship for health care quality to be improved?" Her response emphasizes the logic of having clinicians vested with authority to establish policies concerning the clinical decision-making. The article discusses the cases defining the medical staff bylaws as contractual in nature, and the problem of hospital attorneys demanding unilateral amendments to bylaws. Bylaw clauses that would chill medical opinion and communication or denigrate clinical recommendations are discussed. Ms. Snelson advocates for the inclusion of the medical staff organization in exclusive contract and other clinical decision-making, and includes sample bylaw language enacting her recommendations.  相似文献
