Case ReportsIntravenous thrombolysis in an elderly patient with acute ischemic stroke masking aortic dissection.
Before thrombolytic treatment for acute ischemic stroke is undertaken, conditions associated with increased risk of hemorrhagic complications, such as an acute aortic dissection (AAD), should be excluded. We report an 80-year-old woman with acute ischemic stroke as the sole clinical manifestation of AAD who was treated with intravenous (IV) tissue plasminogen activator (tPA). She had no history of hypertension or any signs or symptoms suggestive of AAD. ⋯ Infusion of tPA was stopped, and subsequent computed tomography angiography confirmed Stanford type A aortic dissection. In this case, prompt neurosonologic evaluation helped us make an appropriate diagnosis and avoid complications related to treatment. Neurosonologic evaluation should be considered as soon as possible in all patients with acute ischemic stroke, especially when thrombolytic treatment is being considered.

Case ReportsRecurrent posterior circulatory emboli from a mildly stenosed bicuspid aortic valve.
Bicuspid aortic valve (BAV) is a common condition but is only rarely associated with embolic complications. We describe a 42-year-old man with recurrent posterior circulatory ischemic strokes that resulted in ataxia and cognitive impairment. Transesophageal echocardiography demonstrated a BAV with mild stenosis, moderate calcification, and a dilated ascending aorta. The degree of calcification and the valve phenotype might be important factors implicating the BAV as a rare cause of ischemic stroke.

Factors associated with misdiagnosis of acute stroke in young adults.
Misdiagnosis or delayed diagnosis of acute ischemic stroke can result in neurologic worsening or a missed opportunity for thrombolysis. Because stroke in young adults is less common than stroke in the elderly, we sought to determine clinical characteristics associated with misdiagnosis of stroke in young adults. Patients from the prospectively maintained Young Stroke Registry in our comprehensive stroke center were reviewed. ⋯ Patients presenting with vertebrobasilar territory ischemia have a greater rate of misdiagnosis. Our study demonstrates the increasing need for "young stroke awareness" among emergency department personnel. Initial misdiagnosis can potentially lead to a lost opportunity for thrombolysis in otherwise good candidates.

Multicenter StudyIs cognitive functioning 1 year poststroke related to quality of life domain?
Previous studies on the association between poststroke cognitive impairment and quality of life (QoL) have shown divergent results. In this study, we investigated the relationships between cognitive functioning and various QoL domains at 1 year poststroke. This was a cross-sectional study, examining 92 patients at 1 year poststroke. ⋯ Controlling for demographic factors and motor impairments resulted in negligible percentages of variance additionally explained by cognitive functioning. The percentages of explained variance were somewhat lower in the analyses with the separate cognitive domains and not significant for depression. Poor cognitive functioning was associated with reduced functional independence, social participation, depressive mood, and life satisfaction 1 year post; however, motor impairment was a stronger determinant of long-term QoL than cognitive functioning.

Multicenter StudyFactors influencing cooperation among healthcare providers in a community-based stroke care system in Japan.
Community-based stroke care in Japan is currently provided in acute hospitals, convalescent rehabilitation units, general practices, sanatorium-type wards, nursing care facilities, and in-home/commuting care services. We conducted a nationwide survey to identify factors influencing cooperation among the various providers of community-based stroke care. We sent questionnaires to 11,178 facilities and assessed the independent variables of excellent and fair cooperation among the care providers. ⋯ The following independent variables were inversely associated with excellent or fair cooperation in the community: area with the higher population density among 3 groups divided by tertile threshold (odds ratio [OR], 0.53; 95% confidence interval [CI], 0.41-0.69), facilities covered by long-term care insurance (OR, 0.27; 95% CI, 0.22-0.34), and insufficient communication with local government (OR, 0.19; 95% CI, 0.14-0.24). Positive independent variables of excellent or fair cooperation were the sharing of patient information in the community (OR, 2.53; 95% CI, 1.78-3.66), use of a scale for assessing activities of daily living (OR, 1.93; 95% CI, 1.42-2.63), appropriate utilization of care support managers (OR, 1.91; 95% CI, 1.43-2.55), and adequate comprehension of the long-term care insurance system (OR, 1.54; 95% CI, 1.24-1.92). Our findings suggest that improved communication between healthcare providers and local government, along with appropriate attention to the problems facing providers covered by long-term care insurance, may improve community-based stroke care in Japan.
