Arterial-esophageal fistulae in patients requiring nasogastric esophageal intubation 总被引:1,自引:0,他引:1
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. 相似文献

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. 相似文献

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. 相似文献

The U.S. Bureau of Mines was established in 1910 to reduce the high accident rate in the nation's coal mines. For 85 years, it conducted a wide variety of tasks related to mining before it was abolished in 1995. The BOM had many technology transfer successes in its lifetime, including more than a dozen R&D100 awards. This essay identifies and discusses five transfer factors that can explain the success (or failure) of many Bureau of Mines projects. These five factors are termed pressure, pitfalls, path, price, and profit. 相似文献
