This report provides the first detailed neuropathological study of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced parkinsonism in humans. All 3 subjects self-administered the drug under the impression it was "synthetic heroin" and subsequently developed severe and unremitting parkinsonism, which was L-dopa responsive, at least in the earlier(More)
This study describes the developmental neuropathology of two infants who survived 7 and 9 years, respectively, an episode of violent shaking (shaken infant syndrome) early in their lives. The shaking injuries include cortical and subcortical contusions, hemorrhages, hypoxic/ischemic and axonal damage, and severe edema. The types, distribution, and(More)
The authors review the research on N,N-dimethyltryptamine (DMT) as a possible "schizotoxin." DMT produces psychedelic effects when administered to normal subjects, the means are present to synthesize it in man, it has occasionally been found in man, and tolerance to its behavioral effects is incomplete. However, DMT concentrations have not been proven to(More)
OBJECTIVE Between 1999 and 2006, there was a 120% increase in the rate of unintentional drug overdose deaths in the United States. This study identifies the prevalence of mental illness, a risk factor for substance abuse, and chronic pain among prescription drug overdose deaths in West Virginia and ascertains whether psychotropic drugs contributing to the(More)
3,4-Methylenedioxymethamphetamine (MDMA or ecstasy) is a commonly consumed recreational drug. As is the case with most secondary amines, MDMA reacts with formaldehyde under acidic conditions to form tertiary amines. This reaction is likely to occur in formalin-fixed tissue. In formalin solutions, MDMA is methylated producing(More)
Median nerve somatosensory evoked potentials were recorded in 21 patients undergoing cardiac surgical procedures utilizing cardiopulmonary bypass, in order to establish the effects of hypothermia, reductions in mean arterial pressure, and alterations in cardiopulmonary bypass flows on evoked potential latency. Induction and maintenance of anesthesia with(More)
