The human homologue of the yeast OGG1 gene, hOGG1, has been cloned, and its genetic structure has been determined. Several polymorphisms in the hOGG1 gene were detected in the Japanese populations, and among them, the Ser-Cys polymorphism at codon 326 has been shown to have a functional difference in complementation of mutant Escherichia coli that is(More)
Okinawa, a group of islands that lie between the East China Sea and the Pacific Ocean, 2000 km south of the Japanese main islands, has a different profile of diseases, ethnicities, and cultures than does the rest of Japan. We examined an Ile462Val polymorphism (CYP1A1*2 allele) of cytochrome P450 IA1 in a hospital-based case-control study of lung cancer(More)
OBJECTIVES This study was designed to evaluate risk factors of infection after bicondylar tibial plateau fractures. We hypothesized that open fractures and smoking would be associated with deep infection requiring reoperation. DESIGN We retrospectively identified all bicondylar (AO/OTA 41-C) tibial plateau fractures treated operatively over an 8-year(More)
BACKGROUND The effect of workers' compensation claims on outcomes after reverse shoulder arthroplasty (RSA) has not been investigated. The purpose of this study was to evaluate outcomes after RSA in patients with a workers' compensation claim and to compare them with a control group without a workers' compensation claim. METHODS We identified 14 primary(More)
Posterior shoulder dislocation is often associated with bone defects. Surgical treatment is often necessary to address these lesions. The aim of the present systematic review was to analyse the available literature concerning bone block procedures in the treatment of bone deficiencies following posterior dislocation. In addition, the methodology of the(More)
The treatment of type III acromioclavicular injuries is controversial. Both conservative and surgical approaches have been successful. Aim of the present study was to prospectively evaluate the results of the modified Cadenat procedure in subjects with type III acromioclavicular joint injuries. Twenty-eight patients with acute type III acromioclavicular(More)
PURPOSE Pediatric obesity is a major public health concern in the United States. We investigated the association of body mass index with presentation and outcome in children with urolithiasis. MATERIALS AND METHODS We identified all patients 2 to 18 years old at our institution with a radiographically confirmed first renal or ureteral stone between(More)
BACKGROUND Management of periprosthetic infection after reverse shoulder arthroplasty (RSA) remains a challenge. Whereas the infection rate after RSA has improved, more information would be helpful to identify patient risk factors for infection after RSA. The purpose of this study was to evaluate risk factors for infection after RSA. METHODS We identified(More)
Post-operative range of motion (ROM) is one of the most important parameters to assess, following total knee arthroplasty (TKA). The aims of the present systematic review were to analyse the available literature and determine if closing the knee in flexion or extension influences post-operative ROM, clinical outcomes, and complications following TKA. A(More)
BACKGROUND The potential adverse effect of preoperative opioid use on outcomes after reverse shoulder arthroplasty (RSA) has not been investigated. The purpose of this study was to evaluate outcomes after RSA in patients with a history of preoperative opioid use and compare them with a control group without a history of preoperative opioid use.
