✦ Synopsis
use one of the familiar grading systems usually employed (5). At best, the semiquantitative assessment of mental state is an art form, not a science. Since the majority of their patients were comatose, it was not an ideal group of patients for assessment of the full range of grades of impairment of consciousness. It is surprising, however, that the correlation between mental state and EEG was so poor, since the criteria for their most abnormal EEG group was so broad, i.e. five or fewer cycles per sec. In any event, the semiquantitative correlation of mental state with EEG was not their primary concern, nor ours.
Finally, the numbers of patients with "pure" hepatic, anoxic and toxic metabolic encephalopathies studied were small, and the statistics about these subgroups were not presented. Therefore, some doubts persist that their findings could represent a Type I1 error. Nevertheless, this is the first objective assessment of the specificity of TPWs in various types of encephalopathy. It appears to show that triphasic waves are not specific for hepatic encephalopathy. Until it is unequivocally shown that this relationship is nonspecific, we suggest that the emperor no longer appear in public undressed. HAROLD 0. CONN, M.D.
