Review Case ReportsRecurrent embolic strokes associated with vertical atlantoaxial subluxation in a patient with rheumatoid arthritis: a case report and review of literature.
We report a 78-year-old woman with rheumatoid arthritis who developed recurrent embolic cerebellar strokes associated with vertical atlantoaxial subluxation (AAS). On contrast angiography, the bilateral vertebral arteries (VAs) were occluded between the C1 and C2 levels, and the distal parts of bilateral VA were supplied by the collateral circulations. Dynamic cerebral angiography and carotid duplex ultrasonography showed that blood flow was substantially decreased in the left VA and left posterior inferior cerebellar artery on cervical anteflexion. It is suggested that vertical AAS reduced the blood flow of collateral circulation in the left VA with cervical anteflexion and might be a cause of recurrent ischemic stroke.

Comparative StudyTrends in antihypertensive drug prescription patterns among ambulatory stroke patients in the United States, 2000-2009.
Although the ambulatory setting is recognized as the best arena for optimizing antihypertensive drug treatment after a stroke, little is known about recent office-based antihypertensive drug treatment patterns in the United States. We assessed national trends in antihypertensive treatment for stroke patients in office-based medical practice. ⋯ Over the last decade, there was a significant rise in the use of antihypertensive drugs and combination of agent classes for patients aged 40 years or older seen in an ambulatory setting with a diagnosis of stroke. PCPs were more likely than neurologists to prescribe these agents.

Hypothyroidism is associated with increased ischemic stroke risk but paradoxically results in more favorable outcomes once a stroke occurs. Whether a similar pattern emerges in patients with primary intracerebral hemorrhage (ICH) is unknown. ⋯ This study suggests that the history of hypothyroidism does not affect clinical severity or outcome after ICH.

Comparative StudyDecompressive hemicraniectomy for malignant hemispheric stroke in the elderly: comparison of outcomes between individuals 61-70 and >70 years of age.
Malignant hemispheric infarction is a life-threatening condition with a high mortality rate. Decompressive hemicraniectomy (DHC) is frequently a life-saving procedure that has shown the highest grade of evidence for patients 18 to 60 years of age. However, the efficacy of DHC in patients>60 years of age has rarely been investigated. ⋯ We suggest that the efficacy of DHC in malignant hemispheric stroke patients between 61 and 70 years of age be further investigated in future randomized trials. By contrast, it appears unlikely that patients>70 years of age would benefit from DHC.

National survey of thrombolytic therapy for acute ischemic stroke in Taiwan 2003-2010.
Data on thrombolytic therapy at the national level is scarce in Asia. Understanding current practice pattern is important for a policy maker in decision making. This cross-sectional study analyzed the utilization pattern of thrombolytic therapy for acute ischemic stroke (AIS) in Taiwan from 2003 through 2010 and identified factors associated with post-therapy intracerebral hemorrhage (ICH) and mortality. ⋯ Patients given thrombolytic therapy in hospitals with thrombolysis cases more than the 5.5/year had a lower risk of ICH (odds ratio: .53; 95% confidence interval: .31-.88). Compared with most developed countries, there is indeed much unmet need for stroke thrombolysis in Taiwan. Effective mechanism should be implemented to increase the thrombolysis rate safely and improve outcome for patients with AIS.
