Question: Abstract: Using neuropsychological testing procedures, we measured the behavioral characteristics of patients with epilepsy unaffected by anticonvulsant drugs and compared these results with control subjects matched for age, sex, and education. In a nationwide VA Cooperative study, 622 patients with well-defined seizure types were given a selected battery of neuropsychological tests prior to and at 1 month after initiation of drug therapy. Seventy-four control subjects were administered the same test battery under standardized conditions at the same VA testing centers. All tests of controls were also repeated 1 month later. The patients with epilepsy scored significantly and consistently below the level of the control subjects on all but three behavioral measures. Differences reaching statistical significance were found on tests of motor function (Finger Tapping, Pegboard, Color Naming), cognitive-attention (Digit Symbol, Discriminative Reaction Time, Word Fluency), and subtests of the Profile of Mood Status (tension, depression, vigor, and confusion). These data provide a profile of behavioral characteristics of unmedicated patients with epilepsy.

Question: Abstract: A study of 79 children with malunion of forearm fractures is presented. Age at the time of injury, the site of the fracture and the degree and direction of angulation at union were correlated with loss of forearm rotation at review 3.5 to 6 years later. Some guidelines are proposed for the acceptability of angular deformity at union, importance being placed on the avoidance of radial deviation of the radius, and the maintenance of the interosseous gap between the shafts of the radius and ulna.

Question: Abstract: The role of optimal placement of electrodes and mode of shock delivery from a defibrillator was examined in dogs with and without myocardial infarction. Single, double and triple truncated exponential shocks separated by 1 ms were delivered through various electrode combinations and cardiac vectors after electrical induction of ventricular fibrillation. A single shock through a pathway not incorporating the interventricular septum (catheter electrodes or epicardial patches between anterior and posterior left ventricle) required the highest total energy (22.6 and greater than 26.4 J, respectively) and peak voltage (1,004 and greater than 1,094 V, respectively) to terminate ventricular fibrillation. A single shock through a pathway including the interventricular septum required lower total energy and peak voltage to defibrillate. Combinations of two sequential shocks between an intracardiac catheter electrode and anterior left ventricular epicardial patch, between the catheter electrode and subcutaneous extrathoracic plate and between three ventricular epicardial patches all significantly reduced total energy (7.7, 8.7 and 7.8 J, respectively) and peak voltage (424, 436 and 424 V, respectively) needed to defibrillate. Three sequential shocks exerted no significant additional reduction in total energy of the defibrillation threshold than did two sequential shocks. Infarcted canine heart required less peak voltage but not total energy to terminate ventricular fibrillation than did noninfarcted heart. Therefore, two sequential shocks over different pathways reduce both total energy and peak voltage required to terminate ventricular fibrillation.
