PURPOSE We report early outcome of our modified papillary muscles approximation (PMA) as an adjunct to mitral annuloplasty (MAP) by analyzing the mitral coaptation zone echocardiographically and clinical outcome in three different procedures. METHODS Mitral valve coaptation depth (MVCD) and tenting area were measured in patients with ischemic (n=8) or(More)
The p16 gene encodes a 16-kDa cyclin kinase inhibitor, and the p14ARF gene a 14-kDa protein, which acts as a cell cycle regulator or tumor suppressor in human cancer cells. Both genes are mapped on chromosome 9p21. Previous studies have suggested that the p16 gene has important roles in head and neck squamous cell carcinoma. To clarify carcinogenesis in(More)
This study investigated postoperative speech function in tongue cancer patients following reconstruction with fasciocutaneous/myocutaneous flaps, to clarify the factor(s) influencing outcome. Eighty-one patients, enrolled from 11 Japanese institutions, were classified into three groups by the site of resection: lateral (N=51), anterior (N=17) and combined(More)
OBJECTIVE To investigate the impact of preoperative identification of the Adamkiewicz artery (AKA) on prevention of spinal cord injury (SCI) through the multicenter Japanese Study of Spinal Cord Protection in Descending and Thoracoabdominal Aortic Repair (JASPAR) registry. METHODS Between January 2000 and October 2011, 2435 descending/thoracoabdominal(More)
To determine the macrophage migration inhibitory factor (MIF) responses to cardiopulmonary bypass (CPB) surgery as well as to investigate their roles in predicting patient outcome, a prospective, observational, pilot study was performed. Thirty patients undergoing cardiovascular surgery with CPB received 10 mg/kg betamethasone immediately before the CPB.(More)
PURPOSE The progression of left ventricular (LV) remodeling and subsequent mitral valve tethering impair the results of reduction annuloplasty for ischemic mitral regurgitation (MR). METHODS We studied 90 patients who underwent surgical repair of ischemic MR between 1999 and 2013 according to our surgical strategy adding submitral and ventricular(More)
OBJECTIVE To examine the effect of migration of the germ of the lateral incisor into the bone for eruption factors on bone bridge resorption. METHODS Twenty-five subjects who underwent secondary alveolar bone graft were enrolled. The volume of the alveolar bone grafts immediately after the operation (V1), bone bridge formation 6 months postoperatively(More)
