Randomized Controlled TrialInfluence of body mass index on prescribing costs and potential cost savings of a weight management programme in primary care.
Prescribed medications represent a high and increasing proportion of UK health care funds. Our aim was to quantify the influence of body mass index (BMI) on prescribing costs, and then the potential savings attached to implementing a weight management intervention. ⋯ Drug prescriptions rise from a minimum at BMI of 20 kg/m(2) and steeply above BMI 30 kg/m(2). An effective weight management programme in primary care could potentially reduce prescription costs and lead to substantial cost avoidance, such that at least 8% of the programme delivery cost would be recouped from prescribing savings alone in the first year.

Randomized Controlled TrialEffects of diagnostic information, per se, on patient outcomes in acute radiculopathy and low back pain.
We conducted a prospective randomized study of patients with acute low back pain and/or radiculopathy to assess the effect of knowledge of diagnostic findings on clinical outcome. The practice of ordering spinal imaging, perhaps unintentionally, includes a large number of patients for whom the imaging test is performed for purposes of reassurance or because of patient expectations. If this rationale is valid, one would expect to see a measurable effect from diagnostic information, per se. ⋯ Patient knowledge of imaging findings do not alter outcome and are associated with a lesser sense of well-being.

Randomized Controlled Trial
Fibromyalgia relapse evaluation and efficacy for durability of meaningful relief (FREEDOM): a 6-month, double-blind, placebo-controlled trial with pregabalin.
This was a multicenter, double-blind (DB), placebo-controlled, randomized discontinuation trial to evaluate the efficacy of pregabalin monotherapy for durability of effect on fibromyalgia (FM) pain. The trial included a 6-week open-label (OL) pregabalin-treatment period followed by 26-week DB treatment with placebo or pregabalin. Adults with FM and 40-mm score on 100-mm pain visual analog scale (VAS) were eligible. ⋯ At the end of DB, 174 (61%) placebo patients met LTR criteria versus 90 (32%) pregabalin patients. Pregabalin was well tolerated, though 178 (17%) discontinued during OL for treatment-related adverse events (AE), and more pregabalin than placebo patients discontinued for AEs during DB. In those who respond, pregabalin demonstrated durability of effect for relieving FM pain.

Randomized Controlled Trial
Efficacy and safety of duloxetine for treatment of fibromyalgia in patients with or without major depressive disorder: Results from a 6-month, randomized, double-blind, placebo-controlled, fixed-dose trial.
The primary objectives of this study were to assess the efficacy and safety of duloxetine for reducing pain severity in fibromyalgia patients with or without current major depressive disorder. This was a 6-month, multicenter, randomized, double-blind, placebo-controlled study. In total, 520 patients meeting American College of Rheumatology criteria for fibromyalgia were randomly assigned to duloxetine (20 mg/day, 60 mg/day, or 120 mg/day) or placebo, administered once daily, for 6 months (after 3 months, the duloxetine 20-mg/day group titrated to 60 mg/day). ⋯ Duloxetine was efficacious in patients both with and without major depressive disorder. There were no clinically significant differences between treatment groups in changes in vital signs, laboratory measures, or ECG measures. Study results demonstrated that duloxetine at doses of 60 mg/day and 120 mg/day appears to be safe and efficacious in patients with fibromyalgia.

Randomized Controlled TrialArthroscopic knee chondroplasty using a bipolar radiofrequency-based device compared to mechanical shaver: results of a prospective, randomized, controlled study.
Both mechanical shavers and radiofrequency-based devices are used to treat symptomatic partial thickness chondral lesions. Controversy exists as to which mode of treatment provides better outcomes. The purpose of this study was to compare clinical results after bipolar radiofrequency-based chondroplasty (RFC) to mechanical shaver debridement (MSD). ⋯ At 1 year, RFC patients had significantly better Tegner score (4.1 +/- 0.8 vs. 2.8 +/- 0.6, P < 0.001) and KOOS domain scores for pain, symptoms, ADL, QOL, respectively (81.1 +/- 8, vs. 59.4 +/- 12.8; 80.7 +/- 7.5 vs. 59.6 +/- 7.5; 81.5 +/- 6.5 vs. 60.1 +/- 6.9; 80 +/- 10 vs. 61.3 +/- 12.5; P < 0.001) than MSD patients. Significantly fewer RFC patients (2% vs 23%, p = 0.026) reported using NSAIDS for knee pain at 1 year. Patients undergoing radiofrequency-based chondroplasty for ICRS grade III medial femoral condyle chondral lesions in conjunction with partial meniscectomy had significantly better clinical outcomes through 1 year than patients with similar pathology receiving chondral debridement using the mechanical shaver.
