Neuropathological changes were studied in a consecutive autopsy series of 135 cases, comprising 73% of all patients who died of AIDS in Switzerland between April 1981 and December 1987. Central nervous system involvement was found in 119 patients (88%), 19 of which had multiple concomitant intracerebral lesions. Among the non-viral opportunistic infections,(More)
We report clinical, neuroradiological and neuropathological findings of monozygotic twin sisters born at 30 weeks' gestation, with pontocerebellar hypoplasia (PCH) similar but not identical to type 2 PCH. They presented with hypertonia, jitteriness, spontaneous and provoked myoclonic jerks (hyperekplexia), apnoeic episodes, and progressive microcephaly.(More)
The human anterior commissure is believed, by extrapolation from data obtained in macaque monkeys, to convey axons from the temporal and orbitofrontal cortex. Reports of interhemispheric transfer and sexual dimorphism related to the anterior commissure, however, make more precise data on the human anterior commissure desirable. We investigated the(More)
Cancerous 'chronic meningitis' may be related to subarachnoid space involvement by solid tumors, hematologic malignancies or rarely intraparenchymatous gliomas. Primary leptomeningeal gliomatosis is a rare condition that is attributed to malignant transformation of heterotopic neuroglial tissue. We discuss the clinical and biological features of a patient(More)
Creutzfeldt-Jakob disease (CJD), a subacute spongiform encephalopathy, is generally included among the group of human and animal diseases which is transmissible by a non-conventional agent, the prion, whose expression is conditioned by the host's genome. The process leading to neuropathological changes is still unknown. We report the neuropathological(More)
Pathogenic mechanisms in human cerebral malaria remain unclear. We reevaluate the role of cell-mediated immune mechanisms in the pathogenesis of this disease based on autopsy findings in a 34-year-old Caucasian male. Histologic examination of brain tissue showed typical features of severe malaria infection (sequestration of Plasmodium falciparum-infected(More)
BACKGROUND AND PURPOSE We sought to quantitatively and qualitatively evaluate the release of atheromatous plaque debris induced by carotid stenting procedures. METHODS Eight patients with severe carotid atheromatous stenoses were treated by stent implantation under distal balloon protection. Blood samplings were obtained after stent deployment in the(More)
PURPOSE After retinal branch vein occlusion (BVO), the arteriole crossing the occluded territories is often constricted. This constriction persists up to several weeks and is correlated with the development of extended territories of nonperfused capillaries. These are results of an investigation supporting the hypothesis that decrease in the production of(More)
