Randomized Controlled Trial Comparative Study
Comparison of epidural analgesia and intercostal nerve cryoanalgesia for post-thoracotomy pain control.
Epidural analgesia is regarded as the gold method for controlling post-thoracotomy pain. Intercostal nerve cryoanalgesia can also produce satisfactory analgesic effects, but is suspected to increase the incidence of chronic pain. However, randomized controlled trials comparing these two methods for post-thoracotomy acute pain analgesic effects and chronic pain incidents have not been conducted previously. ⋯ Both thoracic epidural analgesia and intercostal nerve cryoanalgesia showed satisfactory analgesia for post-thoracotomy acute pain. The incidence of post-thoracotomy chronic pain is high. Cryoanalgesia may be a factor that increases the incidence of neuropathic pain.

Randomized Controlled Trial Multicenter Study
Pregabalin for relief of neuropathic pain associated with diabetic neuropathy: a randomized, double-blind study.
Seven published, randomized, placebo-controlled clinical trials with pregabalin have shown robust efficacy for relief of neuropathic pain from DPN and PHN. An investigation of the efficacy and safety of twice daily pregabalin enrolled 395 adults with painful DPN for > or = 1 year in a 12-week, double-blind, placebo-controlled trial. Patients were randomized to placebo, 150, 300, or 600 mg/day pregabalin (n = 96, 99, 99, and 101). ⋯ Pregabalin 600 mg/day was significantly superior to placebo in improving pain-related sleep-interference scores (p = 0.003), PGIC (p = 0.021), and CGIC (p = 0.009). (Neither pregabalin 150 nor 300 mg/day separated from placebo on these measures, largely because of an atypically large placebo response in one country representing 42% of patients.) All pregabalin dosages were superior to placebo in improving EQ-5D utility scores (all p > or = 0.0263 vs placebo). Pregabalin was well tolerated at all dosages; adverse events were generally mild to moderate. Number needed to harm (discontinuation because of adverse events) was 10.3 for pregabalin 600 mg/day.

Randomized Controlled Trial
Home visits by specially trained nurses after discharge from multi-disciplinary pain care: a cost consequence analysis based on a randomised controlled trial.
To analyse the cost consequences of a nurse follow-up intervention for chronic non-malignant pain patients discharged from multidisciplinary pain treatment. ⋯ The nurse intervention did not significantly influence patients' health status. Patients in the intervention group tended to use fewer health care resources than those in the control group and the cost of the intervention was more than balanced out by savings in other health care resources.

Randomized Controlled Trial
Antihyperalgesic and analgesic properties of the N-methyl-D-aspartate (NMDA) receptor antagonist neramexane in a human surrogate model of neurogenic hyperalgesia.
NMDA-receptors are a major target in the prevention and treatment of hyperalgesic pain states in neuropathic pain. However, previous studies revealed equivocal results depending on study design and efficacy parameters. We tested the analgesic (generalized reduction of generation and processing of nociceptive signalling) and anti-hyperalgesic (prevention of central sensitization) properties of the NMDA-receptor antagonist neramexane and the potassium channel opener flupirtine in the intradermal capsaicin injection model. ⋯ The results suggests that in a human surrogate model of neurogenic hyperalgesia a single low-dose of neramexane had a marked analgesic effect in the sensitized and in the non-sensitized state and thus may be a useful drug to treat the enhanced pain sensitivity in neuropathic pain patients. Its efficacy may be based on analgesia rather than anti-hyperalgesia or anti-windup. In contrast, flupirtine showed neither an analgesic nor an anti-hyperalgesic effect at a dose used for the treatment of postoperative pain.

Randomized Controlled Trial
A randomised controlled study of reflexology for the management of chronic low back pain.
The use of complementary and alternative medicine (CAM) for the management of chronic low back pain (CLBP) continues to rise. However, questions regarding the efficacy of many CAM therapies for CLBP remain unresolved. The present study investigated the effectiveness of reflexology for CLBP. ⋯ There was a main effect of pain reduction, irrespective of group. Trends in the data illustrated the pain reduction was greatest in the reflexology group. Thus, the current study does not indicate that adding reflexology to usual GP care for the management of CLBP is any more effective than usual GP care alone.
