Chlorpromazine combined with cidofovir for treatment of a patient suffering from progressive multifocal leukoencephalopathy.

We report on a stem cell-transplanted patient with B cell chronic lymphatic leukemia who presented with a subacute onset of focal neurological deficits, gait abnormalities, emotional lability and dementia. Progressive multifocal leukoencephalopathy was diagnosed by magnetic resonance imaging (MRI) of the brain and detection of JC virus genome in the cerebrospinal fluid. Cidofovir and the 5HT2A receptor antagonist chlorpromazine were subsequently administered.

Extent of early ischemic changes on computed tomography (CT) before thrombolysis: prognostic value of the Alberta Stroke Program Early CT Score in ECASS II.

Background And Purpose: The significance of early ischemic changes (EICs) on computed tomography (CT) to triage patients for thrombolysis has been controversial. The Alberta Stroke Program Early CT Score (ASPECTS) semiquantitatively assesses EICs within the middle cerebral artery territory using a10-point grading system. We hypothesized that dichotomized ASPECTS predicts response to intravenous thrombolysis and incidence of secondary hemorrhage within 6 hours of stroke onset.

"Clinical-CT mismatch" and the response to systemic thrombolytic therapy in acute ischemic stroke.

Background And Purpose: Mismatch between clinical deficits and imaging lesions in acute stroke has been proposed as a method of identifying patients who have hypoperfused but still have viable brain, and may be especially apt to respond to reperfusion therapy. We explored this hypothesis using a combined database including 4 major clinical trials of intravenous (IV) thrombolytic therapy.

Methods: To determine what the radiological correlates of a "matched" functional deficit are, we calculated the relationship between the ASPECT score of the 24-hour (follow-up) CT scan and the 24-hour National Institutes of Health Stroke Scale (NIHSS) score on the subsample with ASPECT scores performed at this time (n=820).
