To review clinical strategies for long-term opioid management as well as strategies to assess and monitor patients with moderate to severe chronic pain who may be at risk for aberrant drug-related behaviors. ⋯ Vigilance and frequent interactions may sometimes be inadequate to prevent problematic behaviors; therefore, pharmacologic strategies designed to deter abusive behaviors are also discussed.

The purpose is to define the origin of radiculopathy of patients with degenerative lumbar scoliosis-stenosis and to assess the correlation between percentage of initial radicular leg pain relief with selective nerve root injections and lateral canal dimensions. ⋯ In degenerative lumbar scoliotic curves, radicular symptoms are attributed mainly to nerve roots exiting from the concavity of the lumbosacral hemicurve. No evidence was found that the rate of initial relief from selective nerve root injections correlates with the degree of stenosis noted in the MRI.

Randomized Controlled Trial Multicenter Study
A multicenter, randomized, double-blind, controlled study of NGX-4010, a high-concentration capsaicin patch, for the treatment of postherpetic neuralgia.
To confirm the efficacy, tolerability, and safety of NGX-4010, an 8% capsaicin dermal patch (capsaicin 640 µg/cm(2) ), in patients with postherpetic neuralgia (PHN). PHN is a chronic pain disorder that can be difficult to treat and for which current treatment options are often limited by poor tolerability. ⋯ In patients with PHN, a single 60-minute application of NGX-4010 produced significant reduction in pain that was maintained over a 12-week period.

Randomized Controlled Trial
Efficacy of diclofenac sodium in pain relief after conventional radiofrequency denervation for chronic facet joint pain: a double-blind randomized controlled trial.
Many patients experience pain for a short duration after conventional radiofrequency (CRF) denervation for lumbar facet pain. The aim of the present study was to evaluate the efficacy and cost of administering diclofenac sodium for the relief of pain after CRF denervation. ⋯ Diclofenac sodium administration improves analgesia and the PSS after CRF denervation. Compared to a 7-day dosage, a 3-day diclofenac sodium therapy has similar efficacy and less cost for the treatment of pain after CRF neurotomy.
