3,4-Methylenedioxymethamphetamine, or MDMA, is increasing in popularity in the United States as a drug of abuse. It has stimulant and empathogenic mood altering properties with the potential to affect psychomotor skills and impact driving. This report reviews the literature relating to the relevant psychomotor effects of the drug, the relationship between dose and blood concentrations, and studies and case reports on specific effects of the drug on driving. The latter reports include both laboratory driving simulator studies and anecdotal reports, and case series. We also report details of eighteen cases of apparent MDMA impaired driving, including six drivers whose blood tested positive for MDMA alone. Most subjects displayed muscle twitching and body tremors, dilated pupils, slow pupillary reaction to light, elevated pulse and blood pressure, lack of balance and coordination, and most were perspiring profusely. Five of the six subjects were given field sobriety tests (one leg stand, walk and turn test), and all five performed poorly. There was no clear correlation between the blood concentration of MDMA and the specific demeanor of the subject. These findings are consistent with other reports, and lead to the conclusion that MDMA use is not consistent with safe driving, and that impairment of various types may persist for a considerable time after last use. 相似文献

A rapid procedure is described for the extraction and analysis of brain samples for cocaine and benzoylecgonine. Human brain tissue was sectioned at autopsy, and samples were subjected to a lipase digestion, subsequent to solid-phase extraction. The distribution of cocaine and benzoylecgonine throughout different regions of the brain was determined by high-performance liquid chromatography. 相似文献

Trazodone is a popular antidepressant medication that has been available for approximately 30 years. It has a reputation as a safe drug with relatively few reported fatalities attributed solely to it. We review the pharmacology and forensic toxicology of trazodone and report toxicology and cause and manner of death in a series of 37 deaths in which trazodone was detected. Although the normal upper therapeutic blood concentration for trazodone is about 2 mg/L, fatalities are rarely attributed solely to it at blood concentrations below 9 mg/L. Considering the pharmacology of the drug, potential interactions between other drugs with serotonin reuptake properties need to be considered, as does the increased susceptibility to the toxic effects in patients with pre-existing heart disease. In the cases reviewed, none were attributed solely to trazodone, although trazodone was frequently present together with other serotonergic drugs, such as the selective serotonin reuptake inhibitors like fluoxetine and sertraline. Ten cases had blood trazodone concentrations above 2 mg/L. Of these cases, trazodone played a primary role in the death of three subjects, with blood concentrations all greater than 9 mg/L. We confirm the conclusions of others that trazodone is a relatively safe drug except in massive overdose, although its toxicity may be influenced by the presence of other drugs and underlying pathophysiology. 相似文献

This paper reviews the complex pharmacology of the new class of antidepressant medications exhibiting selective inhibition of serotonin reuptake. The four selective serotonin reuptake inhibitors (SSRIs) considered--fluoxetine, fluvoxamine, sertraline and paroxetine--can result in toxicity and death through contributing to serotonergic excess resulting in serotonin syndrome, inhibiting the metabolism of other centrally acting drugs, leading to accumulation of toxic concentrations, and exerting complex vasoactive effects on the vascular smooth muscle. This latter feature is of particular concern in patients with preexisting heart disease. An analytical method involving isolation of the drugs by liquid/liquid extraction at alkaline pH into n-butyl chloride, and analysis by gas chromatography/mass spectrometry (GC/MS) is described, together with some of its limitations. Toxicologic and cause and manner of death data were examined in 60 deaths involving fluoxetine, 5 involving fluvoxamine, 75 involving sertraline, and 28 involving paroxetine. Deaths involving drug toxicity were generally a result of ingestion of multiple drugs, and in only a small number of the cases was death attributed principally to the SSRI involved. The potential for drug interactions between members of this class of drugs is discussed as well as their metabolites and a variety of other therapeutic and abused drugs which can contribute to their toxicity. In the absence of other risk factors, the lowest concentrations determined to have resulted in death were 0.63 mg/L for fluoxetine, 0.4 mg/L for paroxetine, and 1.5 mg/L for sertraline. We had insufficient data to make even this crude assessment for fluvoxamine. Drug-induced elevation of serotonin concentrations may be a significant risk factor for patients with atherosclerotic cardiovascular disease (ASCVD). Other factors including preexisting disease and the presence of other drugs and their pharmacology need to be carefully considered before determining the appropriate cause and manner of death in these cases. 相似文献

The authors present a case of a middle aged attorney who suffered from hyperparathyroidism and a psychotic disorder. It is possible that the hyperparathyroidism may have precipitated an acute psychotic delusional rage leading to an attempted mass murder. They discuss the relationship between hyperparathyroidism and neuropsychiatric symptoms in consideration of available research. 相似文献

This report describes the death of a four-month-old Hispanic male which may be related to benzocaine toxicity. A toxicological evaluation revealed benzocaine at a concentration of 3.48 mg/L, and postmortem methemoglobin of 36% (normal 0.4-1.5). Methemoglobinemia is a complication of benzocaine toxicity. In light of the toxicology findings, the coroner investigated the source of the benzocaine and discovered that the child was treated with Zenith Goldline Allergen Ear Drops containing 0.25% w/v benzocaine and 5.4% w/v antipyrine. There was an admission by a caregiver that on the day prior to the child's death, he had been treated with three times the prescribed dose. Blood benzocaine concentrations in nine other unrelated cases were determined and concentrations ranged from <0.05-5.3 mg/L (mean 1.48 mg/L). Seven of the nine cases were positive for drugs of abuse, and one additional case was described as a known drug user. Methemoglobin in these benzocaine positive cases ranged from 6-69%; however, methemoglobin concentrations in postmortem cases are frequently elevated and should be interpreted with caution. The unknown significance of the benzocaine, and the circumstances of the case raise questions about the ultimate attribution of this death to SIDS. 相似文献
