The effect of dilation of the tibial tunnel on the strength of hamstring graft fixation using interference screws was evaluated. In all, 28 RCI screws were tested in male human tibia-hamstring constructs with tibial tunnels reamed or dilated to the respective size of the graft diameter. Dilation of the tibial tunnel failed to significantly enhance hamstring(More)
Under mechanical volume-controlled ventilation, the intensive care patient can develop intrinsic positive end-expiratory pressure (iPEEP); that is, the passive expiration is terminated by the following inspiration before the alveolar pressure comes to its physical equilibrium value. We present a mathematical method to estimate this alveolar dynamic iPEEP(More)
Prolonged clotting times and reduced levels of clotting factors have been reported in hematin-treated patients. This effect persists for up to 5 hr after hematin infusion, associated with plasma levels ranging from 0.01 to 0.04 mg/ml. Therefore we performed in vitro studies to investigate the effects of hematin on fibrinogen, thrombin, factor VIII:C, and(More)
The effects of diflunisal, a nonacetylated difluorinated salicylate, on platelet function were compared with those of aspirin and placebo. In a randomized, double-blind trial, normal subjects were given diflunisal, 250, 500, or 1,000 mg twice daily; aspirin, 650 or 1,300 mg twice daily; or placebo for 8-day periods. Difunisal, 250 mg, had no effect on(More)
In January 1986, a cooperative study was started at the Katharinenhospital in Stuttgart, FRG (modified Dornier HM-3) and Kreiskrankenhaus in Kempten, FRG (Wolf Piezolith 2200) to evaluate the range of indications, efficacy and required anesthesia of both lithotriptors. Stone classification and general indications for interventional therapy were similar in(More)
(2R, 4R)4-methyl-1-[N alpha-(3-methyl-1,2,3,4-tetrahydro-8-quinoline- sulfonyl)-L-arginyl]-2-piperidine carboxylic acid monohydrate (MCI-9038) was found to be a potent synthetic inhibitor of thrombin. In concentrations as low as 1 microM, the thrombin time, prothrombin time, and partial thromboplastin time were more than doubled. The venom (Bothrops atrox)(More)
BACKGROUND To determine range of motion and capsular characteristics of dominant and nondominant shoulders in baseball players. Our hypothesis was that there is a significant difference between dominant and nondominant range of motion in collegiate baseball players with unoperated and without shoulder pain. METHODS DESIGN prospective, range of motion(More)
A double-blind, randomized, placebo-controlled clinical trial was conducted to determine whether fibrinolysis was increased by the chronic administration of aspirin or diflunisal. Healthy male and female volunteers were randomized to receive either aspirin (1,300 mg every 12 h; 10 subjects), diflunisal (1,000 mg initially, then 500 mg every 12 h; 10(More)
