Should urinary catheters be avoided in patients with total joint arthroplasty?

Patients undergoing total joint arthroplasty typically have indwelling urinary catheters placed preoperatively to decompress the bladder, assess urinary output, and prevent postoperative urinary retention. However, catheterization is associated with several complications and increased hospital length of stay, and research supports eliminating routine placement of urinary catheters in most patients undergoing elective joint arthroplasty and certain general surgeries lasting no more than 2 hours.

Pigmented villonodular synovitis of the temporomandibular joint: a report of two cases.

Pigmented villonodular synovitis is a benign but locally destructive disease that originates in the synovial membranes of the joints. It is a proliferative disorder of unknown etiology, and it is usually monarthric. Approximately 80% of cases involve the knee; the hip, ankle, foot, hand, elbow, and shoulder account for most other cases.

Population variability in the effect of aspirin on platelet function. Implications for clinical trials and therapy.

Little or nothing is known about how the inhibitory effect of aspirin on platelets distributes in the general population. We describe a simple whole-blood assay for the extent of aspirin-induced inhibition of platelet aggregation and its application to 31 aspirin-treated subjects. Platelet inhibition to two or more 325-mg aspirin tablets was measured using a newly developed method in 31 healthy, young adults.
