Randomized Controlled Trial
Safety of a novel parenteral formulation of diclofenac after major orthopedic or abdominal/pelvic surgery in a population including anticoagulated, elderly or renally insufficient patients: an open-label, multiday, repeated dose clinical trial.
Decisions to use or avoid nonsteroidal anti-inflammatory drugs (NSAIDs) for postsurgical pain are often influenced by concerns about bleeding and renal adverse effects. The objective of this study was to evaluate the safety of a novel parenteral NSAID, hydroxypropyl-β-cyclodextrin (HPβCD) diclofenac, in a large postsurgical patient population, with particular focus on bleeding and renal effects. ⋯ In addition to its previously demonstrated efficacy, this study provides evidence of HPβCD diclofenac's safety in a large postsurgical population including anticoagulated, elderly or renally insufficient patients. Because study exclusion criteria were minimal, these findings may be broadly generalizable to populations commonly treated in clinical practice.

Randomized Controlled Trial Comparative Study
The safety and efficacy of KAI-1678- an inhibitor of epsilon protein kinase C (εPKC)-versus lidocaine and placebo for the treatment of postherpetic neuralgia: a crossover study design.
Postherpetic neuralgia (PHN) occurs in approximately 10-20% of patients with herpes zoster, and the risk increases with age. In this clinical trial, we evaluated the analgesic properties of KAI-1678-an inhibitor of epsilon protein kinase C-in the treatment of neuropathic pain in patients with PHN. ⋯ We conclude that KAI-1678 is not efficacious as an acute analgesic for chronic neuropathic pain because of PHN. However, for the first time, the results demonstrate that subcutaneous infusions of lidocaine are effective in treating neuropathic pain. The results of lidocaine treatment also indicate that the crossover study design was adequate to detect a clinically meaningful response in this analgesia study.

To assess the effects of a 9-week yoga intervention on chronic nonspecific neck pain 12 months after completion. ⋯ A 9-week yoga intervention improved pain and neck-related disability for at least 12 months after completion. Sustained yoga practice seems to be the most important predictor of long-term effectiveness.

Randomized Controlled Trial
Predicting response to pregabalin from pretreatment pain quality: clinical applications of the pain quality assessment scale.
The aim of this study is to assess the Pain Quality Assessment Scale (PQAS) in predicting pregabalin in peripheral neuropathic pain (NP). ⋯ Pretitration PQAS scores reliably predicted pregabalin responders in patients with NP.

Randomized Controlled Trial Comparative Study
Postoperative analgesia in children after propofol versus sevoflurane anesthesia.
Postoperative analgesia remains a problem, especially in pediatric patients. We hypothesize that patients anesthetized with sevoflurane have more postoperative pain than with propofol. ⋯ In children, anesthesia maintenance with propofol was associated with a significantly lower incidence of postoperative pain than with sevoflurane.
