MMN and Differential Waveform
A mismatch negativity response (MMN) and a new differential waveform were derived in an effort to evaluate a neural refractory or recovery effect in adult listeners. The MMN was elicited using oddball test runs in which the standard and deviant stimuli differed in frequency. To derive the differential waveform, the same standard and deviant stimuli were presented alone. MMN responses were obtained by subtracting the averaged responses to standards from the deviants. The differential waveforms were obtained by subtracting the averaged responses to standards presented alone from deviants presented alone. Scalp topography for the MMN and differential waveforms were similar. A significant (p < .05) positive and negative correlation was found between the earlier and later components of the bimodal MMN and the N1 and P2 component of the differential waveform, respectively. Further, N1 and P2 of the differential waveform were significant (p < .05) predictor variables of early and late peak amplitudes of the MMN. These results suggest that refractory effects may overlay/modify the morphology of the MMN waveform

Malpractice and Patient Safety Concerns.
Objectives"Assurance behaviors," a type of defensive medicine, involve physicians' utilization of additional patient services to avoid adverse legal outcomes. We aim to compare the use of clinical behaviors (such as ordering additional tests, services, and consultations) due to malpractice concerns with the same behaviors due to patient safety concerns.MethodsA national sample of dermatopathologists (n = 160) completed an online survey.ResultsParticipants reported using one or more of five clinical behaviors due to concerns about medical malpractice (95%) and patient safety (99%). Self-reported use of clinical behaviors due to malpractice concerns and patient safety concerns was compared, including ordering additional immunohistochemistry/molecular tests (71% vs 90%, respectively, P < .0001), recommending additional surgical sampling (78% vs 91%, P < .0001), requesting additional slides (81% vs 95%, P < .0001), obtaining second reviews (78% vs 91%, P < .0001), and adding caveats into reports regarding lesion difficulty (85% vs 89%, P > .05).ConclusionsDermatopathologists use many clinical behaviors both as assurance behaviors and due to patient safety concerns, with a higher proportion reporting patient safety concerns as a motivation for specific behaviors
