Clinical TrialUsefulness of triphasic perfusion computed tomography for intravenous thrombolysis with tissue-type plasminogen activator in acute ischemic stroke.
Intravenous thrombolysis for acute ischemic stroke has been investigated in several clinical trials without enough information on collateral blood flow and perfusion deficit in the ischemic areas. The therapeutic time window varies from patient to patient depending on these factors. Triphasic perfusion computed tomography (TPCT) can provide this information as reliably as conventional angiography. ⋯ Thrombolysis can be safely performed within 3 or 7 hours of stroke onset according to the extent of severe perfusion deficit on TPCT. A larger extent of moderate perfusion deficit on TPCT may predict early improvement after thrombolysis.

Case ReportsIdiopathic stabbing headache associated with monocular visual loss.
Idiopathic stabbing headache, which is a brief, sharp, severe jabbing pain that is confined to the head, responds well to treatment with indomethacin sodium. It may occur as a primary entity but more likely is associated with other types of headache, including migraine. ⋯ A case of idiopathic stabbing headache associated with monocular visual loss was relieved by oxygen and indomethacin therapy.
