Treatment and Clinical Outcome in Patients With Basilar Artery Occlusion To the Editor: We read with great interest the recent article by Lindsberg and Mattle1 in which they found, in a review of published case series, that patients with basilar artery occlusion treated with intra-arterial and intravenous thrombolysis (IVT) have similar outcomes. We wonder whether they also compared their 2 gro...

We describe exceptional high-frequency hearing and vocalizations in a genus of pygopod lizards (Delma) that is endemic to Australia. Pygopods are a legless subfamily of geckos and share their highly specialized hearing organ. Hearing and vocalizations of amniote vertebrates were previously thought to differ clearly in their frequency ranges according to their systematic grouping. The upper freq...

Objective The objective of this study is to determine whether structural features of the vertebrobasilar arterial system are related to migraine. Background Alterations in cerebral vascular structure and function have been associated with migraine, possibly mediated by hypoperfusion and/or endothelial dysfunction triggering cortical spreading depression. Vessel tortuosity, in particular, has ...

The possible synergism between noise and aspirin for causing cochlear damage was examined histologically. Six chicks fed aspirin for five days and five chicks fed a normal diet only were paired and placed in sound chambers. They were exposed to a 1500-Hz tone at 115 dB sound pressure level for eight hours. The mean serum salicylate level just before noise exposure was 24 mg/dL (1.74 mmol/L). Te...

The effect of unilateral basilar papilla removal on glucose uptake in the 2nd and 3rd order auditory nuclei in the chick's brain stem, nucleus magnocellularis and nucleus laminaris, respectively, was examined with [3H]2-deoxy-D-glucose (2-DG) autoradiography. The tissue was processed according to a thaw-mount technique, and the number of grains in the resulting autoradiographs was counted to as...

Clinical and radiologic findings in 13 patients (11 women, 2 men) with extracranial vertebral artery dissection are reported. Dissection was spontaneous in 8 patients, occurred after neck manipulation in 2 and after a potential minor injury to the neck in 3. Six had a history of common migraine, 4 were using oral contraceptives at the time of dissection, and 3 had fibromuscular dysplasia. Disse...

temporal lobe, hippocampus or parahippocampal area is one possible cause [3] . Angioplasty with stenting of the posterior circulation is becoming a widely available neurointervention in patients with stenosis of the vertebral or basilar artery. We describe a patient with TGA following angioplasty with stenting of the vertebral artery. Dear Sir, Transient global amnesia (TGA) is a sudden-onset c...
