Diagnosis of Waldenstrom Macroglobulinemia Using Postoperative Histopathology During Routine Total Knee Arthroplasty: A Case Report.

Case: We present a 63-year-old patient diagnosed with Waldenstrom macroglobulinemia (WM) through histopathology of bone tissue after total knee arthroplasty for routine osteoarthritis. The patient, surgical team, and the pathologist were unaware of this diagnosis before the surgery.

Conclusion: The cost-effectiveness of routine histopathologic examination of bone cuts and synovial samples after total joint arthroplasty continues to be a source of debate.

Dissociation of a Medial Pivot Polyethylene in a Kinematically Aligned Total Knee Arthroplasty.

An 81-year-old male patient who underwent a Medacta GMK sphere kinematically aligned (KA) total knee arthroplasty (TKA) for end-stage knee osteoarthritis presented with a dislocated medial pivot (MP) tibia polyethylene (PE) insert on routine six-week postoperative x-rays. The patient presented asymptomatic with a normal range of motion. Dissociation of a fixed-bearing (FB) PE implant is an uncommon complication after TKA.

Efficacious, effective, and embedded interventions: implementation research in infectious disease control.

Background: Research in infectious disease control is heavily skewed towards high end technology; development of new drugs, vaccines and clinical interventions. Oft ignored, is the evidence to inform the best strategies that ensure the embedding of interventions into health systems and amongst populations. In this paper we undertake an analysis of the challenge in the development of research for the sustainable implementation of disease control interventions.

Downhill ski injuries in children and adolescents.

Downhill skiing is considered to be an enjoyable activity for children and adolescents, but it is not without its risks and injuries. Injury rates now range between 3.9 and 9.

Comparison of muscle force production using the Smith machine and free weights for bench press and squat exercises.

The Smith machine (SM) (vertical motion of bar on fixed path; fixed-form exercise) and free weights (FWs) (free-form path) are commonly used strength training modes. Exercisers may need to alternate between types of equipment, depending on testing, training, rehabilitation, and/or the exercisers' goals. The purposes of this study were to compare muscle force production for SM and FWs using a 1 repetition maximum (1RM) for the parallel back squat and supine bench press exercises and to predict the 1RM for one mode from 1RM on the other mode.

Physiological and sport-specific skill response of olympic youth soccer athletes.

Although many studies have been focused on soccer athletes, no comprehensive studies have been conducted on adolescent soccer athletes in the United States. Therefore, the purpose of this study was to quantify the physiological and sport-specific skill characteristics of Olympic Developmental Program (ODP) soccer athletes by age group and game experience. Following written, informed consent, 59 male athletes (age = 14.
