BACKGROUND Patients treated with methotrexate for rheumatoid arthritis often improve but continue to have active disease. This study was undertaken to determine whether the addition of etanercept, a soluble tumor necrosis factor receptor (p75):Fc fusion protein (TNFR:Fc), to methotrexate therapy would provide additional benefit to patients who had(More)
OBJECTIVE To evaluate physician control of needle and syringe during aspiration-injection syringe procedures by comparing the new reciprocating procedure syringe to a traditional conventional syringe. METHODS Twenty-six physicians were tested for their individual ability to control the reciprocating and conventional syringes in typical(More)
The Extension for Community Healthcare Outcomes (ECHO) Model was developed by the University of New Mexico Health Sciences Center as a platform to deliver complex specialty medical care to underserved populations through an innovative educational model of team-based interdisciplinary development. Using state-of-the-art telehealth technology, best practice(More)
OBJECTIVE The present randomized controlled trial compared arthrocentesis of the effusive knee followed by corticosteroid injection performed by the conventional anatomic landmark palpation-guided technique to the same procedure performed with ultrasound (US) needle guidance. METHODS Sixty-four palpably effusive knees were randomized to (i)(More)
PURPOSE To determine the control and performance characteristics of eight different suction biopsy devices. MATERIALS AND METHODS Physician control of the syringe and needle was measured precisely with the validated linear displacement method during the aspiration phase and during five biopsy passes. The visual analog scale was used to measure operator(More)
BACKGROUND The extended knee lateral midpatellar portal for intraarticular injection of the knee is accurate but is not practical for all patients. We hypothesized that a modified anteriolateral portal where the synovial membrane of the medial femoral condyle is the target would be highly accurate and effective for intraarticular injection of the knee.

Needle phobia--fear of medical devices--is a significant problem in pediatric and adult chemotherapy patients. Stress-reducing medical devices is a new, effective cognitive therapy for needle phobia. Twenty-five pediatric and 25 adult chemotherapy patients were randomly exposed to conventional or stress-reducing decorated butterfly needles and syringes.(More)
OBJECTIVE To identify and integrate new safety technologies into outpatient musculoskeletal procedures and measure the effect on outcome, including pain. METHODS Using national resources for patient safety and literature review, the following safety technologies were identified: a safety needle to reduce inadvertent needlesticks to heath care workers, and(More)
The role of enkephalins, beta-endorphin, or other neuropeptides produced by the nervous system in the alteration of immune responsiveness is generally unknown. The present studies were undertaken to investigate the role of these neuropeptides in the modulation of human spontaneous cytotoxicity induced by natural killer (NK) cells. Natural cytotoxicity was(More)
BACKGROUND Hemodialysis (HD) is associated with protein catabolism and augmented apoptosis. Although the effect of metabolic acidosis and inflammatory cytokines on activation of the ubiquitin-proteasome pathway and branched-chain keto acid dehydrogenase (BCKAD) is well known, the effect of HD on these pathways remains unexplored. METHODS Twelve patients(More)
