Multicenter StudyThe impact of intracranial carotid artery calcification on the development of thrombolysis-induced intracerebral hemorrhage.
We aimed to assess whether intracranial carotid artery calcification (ICAC) evident on head computed tomography is a risk factor for symptomatic intracerebral hemorrhage (sICH) following tissue plasminogen activator (tPA) treatment for acute stroke. ⋯ A significantly higher percentage of patients with moderate to severe ICAC developed ICH following tPA administration for stroke. ICAC severity is an independent risk factor for ICH events. ICAC severity can help predict short-term and long-term functional dependency in tPA-treated patients, although this can be confounded by other cardiovascular risk factors and stroke severity.

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.

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 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.

A proposal for the classification of etiologies of neurologic deterioration after acute ischemic stroke.
Neurologic deterioration (ND) occurs in one third of patients with ischemic stroke and contributes to morbidity and mortality in these patients. Etiologies of ND and clinical outcome according to ND etiology are incompletely understood. ⋯ In the present study, the authors identified probable etiologies of ND after ischemic stroke. Delineating the cause of ND could play an important role in the management of the patient and help set expectations for prognosis after ND has occurred. Prospective studies are needed to validate these proposed definitions of ND.
