The utility and validity of the diatom test for drowning was studied using a retrospective analysis of 771 cases of drowning mostly from Ontario, Canada, over the period 1977 to 1993. In this article (part one), the utility of the test was assessed using an analysis of test outcomes. In the companion article (part two), the validity of the test was assessed(More)
On October 9, 2001, a letter containing anthrax spores was mailed from New Jersey to Washington, DC. The letter was processed at a major postal facility in Washington, DC, and opened in the Senate's Hart Office Building on October 15. Between October 19 and October 26, there were 5 cases of inhalational anthrax among postal workers who were employed at that(More)
We describe two previously unreported associations in four cases. The first two cases demonstrate an association between segmental mediolytic arteriopathy and vascular Ehlers-Danlos syndrome. The second two cases illustrate an association between vascular Ehlers-Danlos syndrome and traumatic subarachnoid hemorrhage. In case 1, there was acute subarachnoid(More)
To assess the contribution of neurofilaments (NF) to the detergent-resistant cortical Lewy body (LB) fibril we extracted LBs from Diffuse LB diseased brains and used monoclonal antibodies to probe Western transfers of solubilized LB-derived protein. Antibodies to epitopes located in the COOH-termini of the 200- and 170-kDa NF subunits (NF-H and NF-M)(More)
Discontinuous non-circumferential lesions of tunica media were observed in four cases of traumatic rupture of the vertebral artery. We hypothesize that these lesions were due to mechanical disruption of smooth muscle cells and the liberation of catabolic enzymes with subsequent degradation of the arterial media. To test this hypothesis, healthy vertebral(More)
BACKGROUND Some people in states of excited delirium die while in police custody. Emerging evidence suggests that physical restraint in certain positions may contribute to such deaths. In this study the authors determined the frequency of physical restraint among people in a state of excited delirium who died unexpectedly. METHODS The authors reviewed the(More)
We report 3 patients with progressive supranuclear palsy (PSP) who developed limb apraxia, focal dystonia, and arm levitation late in the course of the disease. Neuropathological examination revealed cortical degeneration in addition to the characteristic pathological findings of PSP. Semiquantitative comparative histological and immunohistological studies(More)
The straight fibrils of the Lewy body contain an epitope related to phosphorylation of the KSPV motif common to the C termini of the 200- and 170-kDa neurofilament subunits and tau. To further characterize this phosphorylated neurofilament/tau epitope in Lewy bodies and to analyze the constituents of isolated Lewy bodies we used a combined biochemical and(More)
The histologic findings in seven cases of traumatic basal subarachnoid hemorrhage from rupture of a vertebral artery are reported. In all cases, blows to the head or neck resulted in minor injury to the cranial or cervical soft tissues but the ipsilateral intracranial segment of the vertebral artery was the site of a longitudinal transmural tear. In(More)
