enterococci are normal inhabitants of gastrointestinal tract, being responsible for 5 to 18% of infective endocarditis and the incidence appears to be increasing. eleven patients with enterococcal endocarditis were studied. in a case series group, 10 men (average 57 years) and one woman (37 years) were studied. two patients had rheumatic heart disease, 5 patients arteriosclerotic disease and on...

Intracranial calcifications may represent calcified cerebral emboli. Calcified emboli may be overlooked even though cerebral CT is widely used as a stroke assessment. We report 4 cases of calcified cerebral emboli and demonstrate the value of CT in the diagnosis and temporal evaluation of such emboli.

BACKGROUND The vascular depression hypothesis and our recent findings of increased frequency of spontaneous cerebral emboli in dementia suggest that such emboli may be involved in the causation of depressive symptoms in dementia. AIMS To evaluate the association between spontaneous cerebral emboli and depressive symptoms in Alzheimer's disease and vascular dementia. METHOD In a cohort of 14...

background: percutaneous transcatheter closure has been proposed as an alternative to surgical closure or long-term anticoagulation in patients with presumed paradoxical embolism and patent foramen ovale (pfo). methods: there were two symptomatic patients (29 and 47 years old) who underwent percutaneous transcatheter closure of pfo after at least two events of cerebral ischemia; one embolic eve...

BACKGROUND AND PURPOSE The observed distribution of cerebral infarcts varies markedly from expectations based on blood-flow volume or Doppler embolus detection. In this study, we used an in vitro model of the cerebral arteries to test whether embolus microspheres encountering the circle of Willis are carried proportionally to volume flow or express a preferred trajectory related to arterial mor...

BACKGROUND AND PURPOSE Doppler ultrasound detection of emboli signals may assist in distinguishing embolic from thrombotic stroke. Selected patient groups have a high incidence of such signals. We have examined consecutive stroke cases to identify the incidence of Doppler emboli in different etiologic subtypes of stroke. METHODS Forty-five patients presenting with first-ever acute carotid ter...

BACKGROUND AND PURPOSE Although thromboembolic stroke is caused by red, white, or mixed clots, the emboli previously used in animal studies on thrombolysis were more often red than white. Because this might be one of the reasons why thrombolysis is less effective in patients than in experimental stroke, we developed a new method of preparing highly standardized red and fibrin-rich white emboli....

Background and Purpose Doppler ultrasound detection of emboli signals may assist in distinguishing erabolic from thrombotic stroke. Selected patient groups have a high incidence of such signals. We have examined consecutive stroke cases to identify the incidence of Doppler emboli in different etiologic subtypes of stroke. Methods Forty-five patients presenting with first-ever acute carotid terr...
