The Effect of Physician Behavior on the Collection of Data

Abstract: Determining the patient's major reasons for seeking care is of critical importance in a successful medical encounter. To study the physician's role in soliciting and developing the patient's concerns at the outset of a clinical encounter, 74 office visits were recorded. In only 17 (23%) of the visits was the patient provided the opportunity to complete his or her opening statement of concerns. In 51 (69%) of the visits the physician interrupted the patient's statement and directed questions toward a specific concern; in only 1 of these 51 visits was the patient afforded the opportunity to complete the opening statement. In six (8%) return visits, no solicitation whatever was made. Physicians play an active role in regulating the quantity of information elicited at the beginning of the clinical encounter, and use closed-ended questioning to control the discourse. The consequence of this controlled style is the premature interruption of patients, resulting in the potential loss of relevant information.

Terminology and classification of the cortical dysplasias.

Abstract: Background: There have been difficulties in achieving a uniform terminology in the literature regarding issues of classification with respect to focal cortical dysplasias (FCDs) associated with epilepsy. Objectives: To review and refine the current terminology and classification issues of potential clinical relevance to epileptologists, neuroradiologists, and neuropathologists dealing with FCD. Methods: A panel discussion of epileptologists, neuropathologists, and neuroradiologists with special expertise in FCD was held. Results: The panel proposed 1) a specific terminology for the different types of abnormal cells encountered in the cerebral cortex of patients with FCD; 2) a reappraisal of the different histopathologic abnormalities usually subsumed under the term “microdysgenesis,” and suggested that this terminology be abandoned; and 3) a more detailed yet straightforward classification of the various histopathologic features that usually are included under the heterogeneous term of “focal cortical dysplasia.” Conclusion: The panel hopes that these proposals will stimulate the debate toward more specific clinical, imaging, histopathologic, and prognostic correlations in patients with FCD associated with epilepsy.

A Proposed Injury Threshold for Mild Traumatic Brain Injury

Abstract: Traumatic brain injuries constitute a significant portion of injury resulting from automotive collisions, motorcycle crashes, and sports collisions. Brain injuries not only represent a serious trauma for those involved but also place an enormous burden on society, often exacting a heavy economical, social, and emotional price. Development of intervention strategies to prevent or minimize these injuries requires a complete understanding of injury mechanisms, response and tolerance level. In this study, an attempt is made to delineate actual injury causation and establish a meaningful injury criterion through the use of the actual field accident data. Twenty-four head-to-head field collisions that occurred in professional football games were duplicated using a validated finite element human head model. The injury predictors and injury levels were analyzed based on resulting brain tissue responses and were correlated with the site and occurrence of mild traumatic brain injury (MTBI). Predictions indicated that the shear stress around the brainstem region could be an injury predictor for concussion. Statistical analyses were performed to establish the new brain injury tolerance level.
