Oregon's guidelines for physician-assisted suicide: a legal and ethical analysis

Oregon's Death with Dignity Act was first passed by a ballot initiative in 1994, but numerous judicial challenges delayed implementation of the Act. In November of 1997, following the United States Supreme Court decisions in Vacco v. Quill and Washington v. Glucksberg, which left the states' power to regulate physician-assisted suicide undisturbed, the Oregon voters upheld their law. Oregon remains the only state in the nation to authorize physician-assisted suicide. The Task Force to Improve the Care of Terminally Ill Oregonians published a Guidebook for health care providers on the Oregon Act, and the New England Journal of Medicine recently issued a special report on the first year's experience under the Act. This paper analyzes the legal context of the Oregon Death with Dignity Act, discusses the efficacy of the tenets in the Guidebook, and explores ethical issues underlying the guidelines, particularly those pertaining to the meaning of a patient's request for assisted suicide and processes supporting informed consent.

Participation of forensic medics in anthropological examinations of the Orthodox church burials

Examinations of the rudiments of the Russian Orthodox Saints are reviewed. The burial of holy people in Russia is described. The results of examinations of rudiments of the Saints, Reverend Iosaph of Belgorod, Cornilai Padansky, and Arsenii Konevsky, are presented. A detailed algorithm of expert steps is suggested.     

Arterial-esophageal fistulae in patients requiring nasogastric esophageal intubation

A rare and potentially fatal cause of hematemesis is fistula formation between the esophagus and the vascular system. A case report of a 39-year-old woman with congenital aortic arch anomalies hospitalized for treatment of head injuries demonstrates the potential for iatrogenic esophageal trauma to initiate fistula formation between the esophagus and an anomalous arterial system. A literature review revealed 6 other cases of vascular-esophageal fistulae caused by nasogastric esophageal intubation. It is concluded that aortic arch anomalies increase the risk of esophageal injury and subsequent fistula formation from nasogastric esophageal intubation. In addition, the clinical features and pathologic findings of vascular-esophageal fistulae are reviewed.     

Unexpected childhood death due to hemolytic uremic syndrome

Two cases of unexpected childhood death due to hemolytic uremic syndrome are reported. A 21-month-old girl who was discovered dead in bed following a short illness was found at autopsy to have overwhelming sepsis resulting from transmural colitis. Escherichia coli serotype 0157A was isolated from the intestine, and renal changes of hemolytic uremic syndrome were found. A 4-year-old girl died suddenly in hospital from intracranial hemorrhage while being treated for hemolytic uremic syndrome-related renal failure. Culture of urine and feces grew verocytotoxin producing E. coli. These cases demonstrate that hemolytic uremic syndrome may be a rare cause of unexpected childhood death and that the diagnosis may not be established prior to autopsy. Postmortem culture of tissues and fluids in cases of suspected sepsis in children may be essential in establishing this diagnosis, because histologic evaluation may be compromised by profound sepsis and tissue putrefaction. Accuracy in diagnosis may have significant public health and medicolegal consequences.     

Discrepancy between CYP2D6 phenotype and genotype derived from post-mortem dextromethorphan blood level

OBJECTIVE: To describe the death of a toddler after a therapeutic dose of dextromethorphan and its investigation. STUDY DESIGN: Case report, cytochrome P450 phenotype and genotype determination in the victim and post-mortem drug redistribution study performed in rats. RESULTS: A 20-month Asian male who received 3 mg of dextromethorphan once at 09:00 h and again at 22:00 h was found dead at 04:35 h. Post-mortem examination showed signs of early bronchopneumonia (bacterial cultures were negative); dextromethorphan and dextrorphan blood concentrations taken from the heart cavity were 500 ng/ml (1. 84 micromol/l) and 200 ng/ml (0.78 micromol/l), respectively. Despite the dextromethorphan level being almost 100-fold higher than expected after therapeutic doses, intentional or unintentional overdose was extremely unlikely; other potential causes were investigated. Post-mortem drug redistribution study performed in rats showed that dextromethorphan does not undergo extensive redistribution after death (6+/-5-fold increase) and could not explain the observed dextromethorphan level. The dextromethorphan/dextrorphan concentration ratio of 2.5 found in this toddler was compatible with a slow CYP2D6 metabolizer phenotype. However, the toddler exhibited a fast metabolizer genotype. Potential reasons for this discrepancy are discussed. CONCLUSION: CYP450 phenotypes derived from post-mortem blood levels should be interpreted with caution and preferably confirmed by a genotype analysis.
