Patient characteristics and psychotropic drug use in a hospital for the mentally retarded were studied. The majority of patients appeared permanent, 80 percent having been there five years. Ages ranged from 2 to 71 years. Most were mildly or moderately retarded. Fifty-five percent had been originally domiciled within two hours driving time of the hospital.(More)
12 The 2002 National Security Strategy of the United States (NSS) was a watershed document in a number of ways—including its assertion that addressing global poverty is important to U.S. national security. For example, the NSS Introduction by President George W. Bush stated that, while poverty does not directly lead to terrorism,“poverty, weak institutions,(More)
BACKGROUND The brain acoustic monitor (BAM), an indicator of cerebral autoregulation, has previously shown high sensitivity but low specificity for computed tomographic (CT) abnormality in patients following the clinical diagnosis of traumatic brain injury. We assessed the utility of the BAM in diagnosing mild TBI (mTBI) in patients with and without normal(More)
BACKGROUND There is no simple way to assess the injured patient after a loss of consciousness. Computed tomographic scanning is required to rule out anatomic injuries, and invasive intracranial pressure monitoring is needed for the patient with severe traumatic brain injury (TBI). We hypothesized that a noninvasive acoustic monitoring system could provide(More)
PURPOSE To determine if a noninvasive brain acoustic monitor can differentiate acoustic responses from "normal patients" and ischemic from hemorrhagic stroke patients. METHODS A laptop-sized passive acoustic monitoring system acquires arterial-pressure-generated signals during a 15-second monitoring session from sensors placed at the radial artery and on(More)
