Background. Plasma platelet-activating factor-acetylhydrolase (PAF-AH) is known to catalyze platelet-activating factor (PAF). The single nucleotide polymorphism (SNP) of plasma PAF-AH gene (G 994 ->T in exon 9) is associated with a decreased level of plasma PAF-AH activity. This study analyzed the risk of the SNP on graft occlusion of femoropopliteal bypass in patients with atherosclerotic...
Background. Off-pump coronary artery bypass grafting (CABG) has been performed since 1996 in our institute, and its application has recently been expanded to patients with three-vessel disease. A study was performed to clarify the benefit of off-pump CABG for patients with three-vessel disease. Methods. Between June 1, 1991 and September 30, 2001, a total of 1089 patients with three-vessel disease...
Background. The purpose of this study was to clarify the still poorly understood dynamics of peritoneal inflammatory cells (PICs) in acute pancreatitis. Methods. Acute pancreatitis of 3 different degrees of severity was induced in male Wistar rats. Peritoneal lavage was performed at 1, 6, 12, and 24 hours after the induction, and the fluids collected were analyzed for the number and subpopulation...
Background. The aim of this study was to compare the incidence of biliary complications after adult living donor liver transplantation (ALDLT) with Roux-en-Y hepaticojejunostomy (R-Y HJ) or duct-to-duct hepaticocholedochostomy (D-D HC). Methods. Biliary complications were reviewed in 20 consecutive ALDLT recipients surviving more than 1 month, including 10 patients who underwent R-Y HJ and 10 patients...
Background. Interpersonal aspects of care, such as the communication behaviors of physicians, are often cited as central to patients' decisions to initiate malpractice litigation. Relatively little is known, however, about the impact of the communication behaviors of surgeons. In the current study, we investigated the relationship between judgments of surgeons' voice tone and their malpractice claims...
Background. Over the decade of the 1990s, hospital stay after operation declined in response to prospective payment and managed care. As a result, complications previously detected and treated in the hospital may have begun to occur after discharge. In addition, discharge to nursing homes and rehabilitation hospitals may have increased. To address these questions, we used a statewide database to look...
Background. Intraductal papillary mucinous tumor (IPMT) is a type of pancreatic cystic neoplasm. IPMT consists of intraductal papillary mucinous adenoma (benign IPMT) and intraductal papillary mucinous carcinoma (malignant IPMT). Preoperative diagnosis of malignancy is difficult; the invasiveness and metastatic character are not well known. The purpose of the study was to evaluate the optimal diagnostic...
Background. We have investigated the correlations among the expression of proliferating cell nuclear antigen (PCNA), p53, p21, and the prognosis of primary gastric lymphoma, and we have investigated apoptosis by using transferase-mediated deoxyuridine triphosphate nick-end labeling staining. Methods. A retrospective study was performed on 33 cases of primary gastric lymphoma that were surgically resected...
Background. Abdominal para-aortic lymph node (APAL) dissection of esophageal cancer is not widely accepted. The aim of this article is to propose the indications for APAL dissection in esophageal cancer patients from the viewpoint of micrometastases. Methods. To evaluate the value of APAL dissection in patients with esophageal cancer, the status of APAL metastases and recurrence in 230 patients with...
Background. Extended lymphadenectomy including lateral node dissection (EXT-L) contributes to a low incidence of local recurrence of lower rectal cancer. However, EXT-L is frequently associated with impairment of sexual and urinary function. We therefore compared the effectiveness of preoperative radiotherapy with that of EXT-L. Methods. One hundred fifteen patients were studied. Seventy-eight patients...
Background. Leflunomide and its metabolite, A77 1726, interfere with pyrimidine metabolism and exert potent immunosuppression in experimental organ transplantation. However, clinical use of the agents has been restrained because of an extended half-life. FK778, one synthetic malononitrilamide derived from A77 1726, is synthesized to overcome this problem while maintaining similar therapeutic efficacy...
Background. New molecular techniques have been designed to detect cancer micrometastases that are otherwise missed by conventional histologic examination. The aim of this study was to establish a sensitive and rapid genetic assay to detect lymph node micrometastasis and to assess its usefulness clinically for cervical lymphadenectomy in esophageal cancer. We have recently shown that metastasis in...
