Randomized Controlled Trial Multicenter Study
A phase 2 study evaluating the efficacy and safety of a novel, proprietary, nano-formulated, lower dose oral diclofenac.
Safety concerns associated with nonsteroidal anti-inflammatory drugs (NSAIDs) have prompted the development of new formulations that minimize adverse events (AEs) and maintain efficacy. ⋯ Lower dose, nano-formulated diclofenac demonstrated good overall efficacy, prompt pain relief, and was well tolerated. These data suggest lower dose nano-formulated NSAIDs could be effective for acute pain and may potentially improve safety and tolerability as a result of using a lower overall dose.

Current treatments for cancer pain are often inadequate, particularly when metastasis to bone is involved. The addition to the treatment regimen of another drug that has a complementary analgesic effect may increase the overall analgesia without the necessity to increase doses, thus avoiding dose-related side effects. This project investigated the synergistic effect of the addition of the potassium channel (KCNQ2-3) modulator flupirtine to morphine treatment in a rat model of prostate cancer-induced bone pain. ⋯ These results suggest that flupirtine in combination with morphine may be useful clinically to provide better analgesia at lower morphine doses in the management of pain caused by tumors growing in bone.

To determine the temporal relationship between pain-related coping strategies and psychosocial factors with non-evoked neuropathic pain (NP) intensity and unpleasantness in patients during the subacute phase of spinal cord injury (SCI). ⋯ Pilot longitudinal data suggest that pain-related coping strategies are adopted early after subacute SCI, and correlate with both pain intensity and unpleasantness. Future longitudinal studies of SCI with sufficient sample size will be instrumental to determine the causal relationship between psychosocial factors and coping strategies on pain.

Randomized Controlled Trial
Effectiveness of water physical therapy on pain, pressure pain sensitivity, and myofascial trigger points in breast cancer survivors: a randomized, controlled clinical trial.
To evaluate the effects of an 8-week water physical therapy program on cervical and shoulder pain, pressure sensitivity, and the presence of trigger points (TrPs) in breast cancer survivors. ⋯ An 8-week water therapy program was effective for improving neck and shoulder/axillary pain, and reducing the presence of TrPs in breast cancer survivors as compared with usual care; however, no significant changes in widespread pressure pain hyperalgesia were found.
