Randomized prospective evaluation of injection techniques for the treatment of lateral epicondylitis.
Summary of "Randomized prospective evaluation of injection techniques for the treatment of lateral epicondylitis."
Lateral epicondylitis is a commonly made diagnosis for general practitioners and orthopedic surgeons. Corticosteroid injection is a mainstay of early treatment. However, conflicting evidence exists to support the use of steroid injection, and no evidence in the literature supports an injection technique.Nineteen patients diagnosed with acute lateral epicondylitis were evaluated to compare the peppered- and single-injection techniques using the Disabilities of the Arm, Shoulder and Hand (DASH) score, visual analog score (VAS), and grip strength. For elbows with a single injection, mean grip strength increased from 22.9 to 27.8 (P=.053), mean VAS pain score decreased from 4.8 to 3.6 (P=.604), and mean DASH score decreased from 2.6 to 1.8 points (P=.026). For elbows with peppered injections, mean grip strength increased from 28.7 to 32.8 (P=.336), mean VAS pain scores decreased from 3.7 to 2.3 (P=.386), and mean DASH score decreased from 2.6 to 1.3 (P=.008).No studies have directly compared the peppered-injection technique to the single-injection technique. Our results suggest that patient outcome is improved with the single injection. The biomechanical or chemical reason for the distinction is yet unknown, but we postulate that the peppered technique may actually further damage the already compromised tendon. The theory that the peppered injection stimulates blood flow may be overestimated or false. Histochemical studies of the pathologic tissue must be performed to further delineate the reason for improved outcomes with the single-injection technique.

Medical and Biotech [MESH] Definitions
Controlled Clinical Trial
Work consisting of a clinical trial involving one or more test treatments, at least one control treatment, specified outcome measures for evaluating the studied intervention, and a bias-free method for assigning patients to the test treatment. The treatment may be drugs, devices, or procedures studied for diagnostic, therapeutic, or prophylactic effectiveness. Control measures include placebos, active medicine, no-treatment, dosage forms and regimens, historical comparisons, etc. When randomization using mathematical techniques, such as the use of a random numbers table, is employed to assign patients to test or control treatments, the trial is characterized as a RANDOMIZED CONTROLLED TRIAL.

Prospective Payment Assessment Commission
The commission charged with evaluating issues and factors which affect the implementation of the PROSPECTIVE PAYMENT SYSTEM.
Hypophysectomy, Chemical
Total or subtotal destruction of the pituitary gland by chemical injection. It is usually achieved by injection of ethyl alcohol via trans-sphenoidal cannulation under stereotaxic control. It is usually performed for the treatment of intractable pain.
Randomized Controlled Trials As Topic
Clinical trials that involve at least one test treatment and one control treatment, concurrent enrollment and follow-up of the test- and control-treated groups, and in which the treatments to be administered are selected by a random process, such as the use of a random-numbers table.
