" Diffuse correlation spectroscopy " (DCS) is a technology for non-invasive transcranial measurement of cerebral blood flow (CBF) that can be hybridized with " near-infrared spectroscopy " (NIRS). Taken together these methods hold potential for monitoring hemodynamics in stroke patients. We explore the utility of DCS and NIRS to measure effects of(More)
We tested a revised version of the Hierarchic Dementia Scale (HDS), proposed by Cole and Dastoor (1980), in order to improve its clinical usefulness and to enrich our knowledge about ageing. The scale was built with 20 subtests which covered the entire range of cognitive and motor functions. Each subtest was hierarchically organized so that success in a(More)
We describe a new cause of spinal cord ischemia illustrated by two cases--compression by the diaphragmatic crus of a lumbar artery giving rise to a spinal artery. The diagnosis has been established by dynamic spinal angiography, showing complete occlusion of the lumbar artery. Surgical section of the diaphragmatic crus prevents irreversible infarction.
A 39-year-old man with livedo reticularis, optic neuropathy and acute ischemic encephalopathy (Sneddon's syndrome) had antiphospholipid antibodies. This primary antiphospholipid antibody syndrome was unsuccessfully treated by anticoagulation, corticosteroids and plasma exchanges. Despite a frank reduction of the circulating antibody titers after plasma(More)
In a 70-year-old male patient with untreated diabetes a febrile orbital apex syndrome of rapid onset revealed a rhino-orbito-cerebral zygomycosis. Biopsies of the ethmoidal mucosa showed numerous colonies of the Rhizopus genus. Despite medical treatment (amphotericin B) and surgery (ethmoidectomy), the patient died within one week. Rhino-cerebral(More)
Two cases of intracranial dural arteriovenous fistulae draining into the medullary veins are reported. One patient was a 68-year old man who experienced brief and repeated episodes of paraplegia, followed by a permanent spinal cord syndrome. The other patient was a 74-year-old woman who rapidly developed a syndrome of the medulla and spinal cord. In both(More)
