Summary: MR-DWI and endoscopy data were prospectively collected throughout IFX treatment. Altogether, 86 lesions from 13 patients given IFX as induction (weeks 0, 2 and 6) and maintenance (5 mg/kg every 8 weeks beginning at week 14) therapy were analyzed with MR-DWI for 0.5-1.5 years from the starting point. Mucosal findings were confirmed by endoscopy at 1 and 3 years (gold standard). Of the 86 lesions, 65 were graded ’0′ and 21 were graded ’1′ based on their hyperintensity (HI; or lack thereof) on MR-DWI. Two Fludarabine cell line years after the first evaluation, 7 of 15 false-negative lesions had turned positive

based on colonoscopy findings, and 60 of 62 true-negative lesions had not. Thus, 0.03% of those predicted to remain in remission had relapsed (negative predictive value 0.9677, p < 0.0001). MR-DWI-HI at 1 year coincided with the presence of endoscopic inflammation, with sensitivity of 66.67%, specificity of 80.52%, and an area under the curve (AUC) value of 0.7359 (0.5479-0.9240, p = 0.0211). The AUC value

of MR-DWI-HI at 3 years was 0.8402 (0.7460-0.9343, p = 0.001) with sensitivity of 94.12% and specificity of 73.91%. Key Message: A definition of the response on the basis of MR-DWI-HI might be helpful for optimizing treatment for patients with CD under treatment with IFX. (C) 2014 S. Karger AG, Basel”
“The posterolateral corner (PLC) is more likely to be injured in combination with the posterior cruciate ligament (PCL) or the anterior cruciate ligament than in SHP099 Others inhibitor isolation. This leads to instability of the knee and loss of function. We hypothesised that combined PCL and PLC reconstruction would restore sufficient stability to allow improvement

in patient symptoms and function.\n\n19 patients who underwent arthroscopic-assisted single-bundle PCL and PLC reconstruction by a single surgeon were analysed retrospectively. The PLC reconstruction was a modified Larson reconstruction of the lateral collateral ligament and the popliteofibular ligament.\n\nThe IKDC and Tegner scores were used to assess outcome. Dial test and varus laxity were used to assess improvements in clinical laxity. Posterior laxity was tested using the KT-1000.\n\nThe mean follow-up was 38 months (+/-(2x standard deviations), Selleck Torin 1 +/- 12.3). There were no postoperative complications. All patients had less than 5 mm posterior step-off. 17 of 19 patients had negative dial and varus stress tests. Measured range of motion was reduced by a mean of 10A degrees, but patients did not report any daily activities restrictions. Tegner scores improved from a median pre-operative value of 2 (range 1-4) to 6 (4-9) at final follow-up. The mean postoperative IKDC score was 86 (+/- 11).\n\nSubjectively, the knee stability achieved allowed daily activities.
