Abnormal sharp transients on electroencephalograms in preterm XXXX with @entity5719 .

@entity1 @entity5719 @entity2406
OBJECTIVE: To determine the clinical significance of abnormal sharp transients other than @entity2406 ( @entity2406 ), electroencephalograms were used for the diagnosis of @entity5719 ( @entity5719 ). STUDY DESIGN: We evaluated 126 electroencephalograms from 93 preterm @entity1 ; 31 @entity1 had @entity5719 , and 62 were control @entity1 . Frontal sharp waves (FS) were defined as sharp transients of positive polarity with an amplitude >100 microV. @entity2406 ( @entity2406 ) were defined as those of negative polarity with an amplitude >150 microV. FS, @entity2406 , or @entity2406 were considered to be present when there were >0.1 per minute. RESULTS: The number of FS per minute was significantly higher in the @entity5719 group than in the control group during days 0 to 4 and 5 to 7. The number of @entity2406 per minute was also significantly higher in the @entity5719 group than in the control group during days 0 to 4, 5 to 7, and 8 to 14. The sensitivity of FS or @entity2406 was relatively high but that of @entity2406 was low. The presence of two or more types of abnormal sharp transients was correlated with a poor outcome. CONCLUSIONS: FS or @entity2406 may be useful for predicting which @entity1 will have @entity5719 .
