Randomized Controlled Trial
Single Paravertebral Injection for Acute Thoracic Herpes Zoster: A Randomized Controlled Trial.
The aim of this study was to evaluate the efficacy of single thoracic paravertebral injection in acute thoracic herpes zoster (HZ) pain, eruptive duration, and the incidence of postherpetic neuralgia (PHN). ⋯ Early single paravertebral blockade in the course of acute thoracic HZ seems to be a safe and effective adjuvant treatment modality.

Randomized Controlled Trial
Assessment of Pain and Activity Using an Electronic Pain Diary and Actigraphy Device in a Randomized, Placebo-Controlled Crossover Trial of Celecoxib in Osteoarthritis of the Knee.
The primary goal was to determine whether a composite measure of pain and activity is a more responsive assessment of analgesic effect than pain alone or activity alone in patients with osteoarthritis (OA) of the knee. ⋯ We have identified composite pain-activity measures that are similarly or more responsive than pain-alone measures in patients with OA. Further research is warranted to determine the optimal method for computing these composites.

Can We "Predict" Long-Term Outcome for Ambulatory Transcutaneous Electrical Nerve Stimulation in Patients with Chronic Pain?
Evidence for effectiveness of transcutaneous electrical nerve stimulation (TENS) is still inconclusive. As heterogeneity of chronic pain patients might be an important factor for this lack of efficacy, identifying factors for a successful long-term outcome is of great importance. ⋯ The results showed that factors associated with a successful outcome in the long term are dependent on definition of successful outcome.
