Increasing hospital admission rates for intracerebral hemorrhage during the last decade.
The incidence and mortality of all types of strokes, including intracerebral hemorrhages, declined during the 1970s. However, some evidence exists that these trends stabilized or reversed during the 1980s. In the present study, a large North American population was observed from 1981 to 1989 to assess changes in the annual hospital admission rates of intracerebral hemorrhage. ⋯ Hospital admission rates for intracerebral hemorrhage nearly doubled from 1981 to 1989. This change may be due to an actual increase in the annual incidence of intracerebral hemorrhage caused by mechanisms that are not yet fully understood.

Changes in cerebral oxygen saturation with change in posture: a preliminary report.
Disease of the major vessels in the neck can disrupt autoregulation and lead to changes in the cerebral blood flow and cerebral autoregulation. These changes can be reflected by means of cerebral oxygen saturation. ⋯ Changes in regional cerebral oxygen saturation inpatients with carotid-vertebral artery disease may reflect disruption of cerebral autoregulation.
