Is hepatitis C virus involved in hepatitis-associated aplastic anemia?
Hepatitis C virus is not a frequent cause of non-A, non-B hepatitis-associated aplastic anemia. Either a non-A, non-B, non-C hepatitis virus is involved in non-A, non-B hepatitis-related aplasia or hepatitis C virus prevalence is underestimated in patients with hepatitis-related aplasia, possibly as a result of immunologic defects.
This study showed that activity levels were significantly reduced following dosing with a benzodiazepine and these changes coincided with impairment of cognitive and psychomotor performance. Actigraphy, therefore, appears to be able to reflect the psychopharmacological effects of a benzodiazepine in changes in daytime function and nocturnal behaviour, which, without waking the subject, is beyond the power of conventional psychometrics.
