Multicenter Study
Efficacy and tolerability of a 5% lidocaine medicated plaster for the topical treatment of post-herpetic neuralgia: results of a long-term study.
Evaluation of long-term efficacy and safety of the 5% lidocaine medicated plaster for neuropathic pain symptoms in patients with post-herpetic neuralgia (PHN). ⋯ This study suggests that long-term treatment with the 5% lidocaine medicated plaster may provide substantial and maintained reductions in pain intensity, and that it is continuously well tolerated in patients suffering from peripheral neuropathic pain associated with previous herpes zoster infection. These findings support the use of the 5% lidocaine medicated plaster as one of the first-line therapies in this population.

Baseline clinical and health-related quality of life (HRQoL) data from a phase 2, multi-site, international, randomized, controlled trial were analyzed to: (1) characterize the health status of patients with relapsing-remitting multiple sclerosis (RRMS), (2) explore cross-sectional relationships between HRQoL and clinical measures, and (3) evaluate differences in HRQoL scores for subsequent validation as minimally important differences (MID). ⋯ Clinical and HRQoL assessments documented health impairments in physical functioning, fatigue, and cognition among these RRMS patients with relatively short disease duration. HRQoL data varied with clinical measures and contributed new information regarding disease burden. The association between clinical and HRQoL measures was limited to cross-sectional analysis and requires confirmation in longitudinal datasets. These findings reflect an ambulatory, early-stage RRMS population that was mostly European in location or descent. The PAMSI also requires further validation as a measure of patient health status.

Multicenter Study
Physicians' attitudes and adherence to use of risk scores for primary prevention of cardiovascular disease: cross-sectional survey in three world regions.
To evaluate physicians' attitudes and adherence to the use of risk scores in the primary prevention of cardiovascular disease (CVD). ⋯ Based on a survey conducted in a 'real-world' setting, risk scores are generally not used by a majority of physicians to guide primary prevention in asymptomatic persons at intermediate risk for CVD. Appropriate prescribing of lipid-lowering therapy in such patients is equally neglected. Changing physicians' attitudes towards the use of CVD risk scores is one of several challenges that need to be addressed to reduce the world-wide burden of CVD.

Randomized Controlled Trial Multicenter Study
Cyclobenzaprine ER for muscle spasm associated with low back and neck pain: two randomized, double-blind, placebo-controlled studies of identical design.
To evaluate efficacy and tolerability of once-daily cyclobenzaprine extended release (CER) 15- and 30-mg capsules in patients with muscle spasm associated with acute, painful musculoskeletal conditions. ⋯ Once-daily CER 15 mg (study 2) and CER 30 mg (study 1) were effective in treating muscle spasm associated with painful musculoskeletal conditions after 4 days of treatment. Differences between CER and placebo groups did not reach statistical significance on all efficacy measures, and the protocols were not powered to detect differences between active treatment arms. CER was generally safe and well tolerated, with low rates of somnolence.

Multicenter Study
Once-daily insulin detemir in a cohort of insulin-naïve patients with type 2 diabetes: a sub-analysis from the PREDICTIVE study.
PREDICTIVE is a large, observational study of the empirical use of insulin detemir in patients with type 1 or type 2 diabetes (T1DM/T2DM). This post hoc analysis evaluates insulin-naïve patients with T2DM uncontrolled on oral antidiabetic drugs (OADs) who were initiated and remained on once-daily insulin detemir for 12 weeks. ⋯ Empirical use of insulin detemir as an insulin initiation strategy can improve glycemic control with good tolerability, including a low risk of hypoglycemia and a weight benefit, in a majority of insulin-naïve patients uncontrolled on OADs.
