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)
Two different ligands, tritiated oxytocin and a newly synthesized and monoiodinated oxytocin antagonist, were used to reveal sites which bind oxytocin in the brainstem and upper spinal cord of 12 human subjects. Tissue sections were incubated with either ligand at a concentration close to their respective dissociation constants determined in human uterus(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)
The immunosuppressive agent FK 506 is widely used in liver transplant patients. Neurotoxicity is a major complication of its use. We report progressive and irreversible neurologic complications occurring in a 39-year-old woman who underwent liver transplantation and was treated with FK 506. Neuropathologic examination revealed multiple vasculitic lesions.(More)
