Randomized Controlled Trial
Single-dose palifermin prevents severe oral mucositis during multicycle chemotherapy in patients with cancer: a randomized trial.
Mucositis can be a serious complication of cancer treatment. Palifermin reduces mucositis when given in multiple doses to patients undergoing hematopoietic stem-cell transplantation. ⋯ A single dose of palifermin before each cycle reduced the incidence and severity of mucositis. The drug was generally well tolerated, but most patients experienced thickening of oral mucosa. Further investigation is needed to determine whether palifermin use will facilitate greater adherence to chemotherapy regimens by reducing mucositis.

Surgical aortic valve replacement (SAVR) is the only treatment known to improve symptoms and survival in patients with severe, symptomatic aortic stenosis. Perioperative mortality, however, is high among many patients for whom SAVR may be indicated. Percutaneous heart valve replacement (PHVR) is an emerging, catheter-based technology that allows for implantation of a prosthetic valve without open heart surgery. ⋯ Differences between patients undergoing PHVR and those typically selected for SAVR make full interpretation of these results difficult. A large, multicenter, randomized, controlled trial comparing PHVR with SAVR or medical management was recently completed, with initial results expected in September 2010. Pending publication of findings from that trial, the available evidence is inadequate to determine the most appropriate clinical role of PHVR or the specific patient populations for whom it might eventually be indicated.
