Preoperatively periprosthetic joint infection with a postoperative complication of 180° rotation of the press-fit femoral component is a rare event, and knowledge of this possible complication is important for arthroplasty surgeons.

Plastics in Total Knee Replacement: Processing to Performance.

Polyethylene (PE) is the key component of total knee replacement (TKR). The wear of polyethylene, a common cause of revision surgeries, depends on multiple factors. The mechanical properties, wear characteristics, and oxidative resistance of PE can be manipulated by the techniques of processing, sterilization, and packaging methods.

Assessing the Use of Loupes and Lights in Dental Hygiene Educational Programs.

The purpose of this study was to explore the use of loupes and lights in dental hygiene programs, to assess why they are being used, and to evaluate at what point in time they are introduced to students within the curriculum. A 20 question survey was developed and pilot tested. The survey was disseminated electronically to 335 dental hygiene program directors in the United States.

Loss of DNA copy number of 10q is associated with aggressive behavior of leiomyosarcomas: a comparative genomic hybridization study.

Leiomyosarcomas (LMS) account for 10-20% of all soft tissue sarcomas. We analyzed 10 primary, 5 metastatic, and 2 recurrent extrauterine LMS. Genomic imbalances were detected in 15 out of the 17 tumors.

Effect of creatine supplementation and a lacto-ovo-vegetarian diet on muscle creatine concentration.

The purpose of this investigation was to examine the effects of preceding oral creatine monohydrate with a lacto-ovo-vegetarian diet on muscle creatine concentration. Thirty-two healthy men, who regularly consumed an omnivorous diet, were randomly assigned to consume a weight maintaining, lacto-ovo-vegetarian (LOV; n = 16) or omnivorous (Omni; n = 16) diet for 26 days. In addition to their assigned diet, on day 22 of the study, subjects were assigned in a double-blind manner to receive either creatine monohydrate (CM; 0.
