We investigated the frequency of new lesions on diffusion-weighted imaging (DWI) after conventional cerebral angiography (CAG) in acute stroke patients and associated factors. ⋯ New DWI lesions were more often seen in patients with CAG than without CAG. However, the difference in number of DWI abnormalities did not reach statistical significance. In CAG patients, fluoroscopy time appears to be an independent factor associated with new DWI lesions.

One third of patients with Guillain-Barré syndrome (GBS) require admission to the intensive care unit (ICU), associated with significant risk of morbidity, mortality, and incomplete recovery. ⋯ Although patients with GBS suffer significant morbidity during protracted ICU stays, with meticulous supportive care, many make gratifying functional recoveries. In severely afflicted patients, this may only be appreciated after extended follow-up.

We report a case of severe neuroleptic malignant syndrome with hyperthermia, rhabdomyolysis and hepatic failure where we applied endovascular cooling in order to reverse hyperthermia. After rapid normalization of core temperature at 37.5 degrees C, the patient's condition improved and CK levels dropped. However, upon withdrawl of endovascular temperature control there was a relapse. This is the first case where endovascular cooling was applied successfully in neuroleptic malignant syndrome.

Conflicting data exist on the role of antiplatelet agents in reducing incident ischemic stroke magnitude, but most prior studies used clinically-assessed neurologic deficit as the index of stroke extent rather than more precise volumetric measurements of infarct size. We assessed the relation of premorbid antiplatelet use to initial diffusion-weighted MRI (DWI) lesion volumes among acute ischemic stroke patients. ⋯ Prior antiplatelet treatment is independently associated with reduced cerebral infarct volume among acute ischemic stroke patients. Premorbid statin use, TIA history and stroke mechanism also predict infarct volume in ischemic stroke.

Spinocerebellar ataxia type 7 mimicking Kearns-Sayre syndrome: a clinical diagnosis is desirable.
Spinocerebellar ataxias are a group of autosomal dominant cerebellar degenerative disorders, which are characterized by clinical and genetic variability. Spinocerebellar ataxia type 7 (SCA7) is less variable in clinical presentation than other SCAs. ⋯ We review the differential diagnosis of cerebellar ataxia with vision loss secondary to retinal pigmentary dystrophy. This paper supports concept of a desirable clinical diagnosis to avoid multiple genetic or invasive testing in children with neurodegenerative disorders.
