Clinical Trial
Prospective clinical study of a new implantable peripheral nerve stimulation device to treat chronic pain.
To evaluate clinical use of the StimRouter, an investigational implanted peripheral nerve stimulator for treating chronic neuropathic pain, using the median nerve as a model for that general application. ⋯ Temporary implant of the StimRouter device resulted in both pain reduction and reduced use of oral opioid pain medication during the 5-day stimulation period. The results suggest that permanent implant of the StimRouter System may be safe and effective for treating chronic peripheral neuropathic pain.

Randomized Controlled Trial
Evaluation of efficacy of the perioperative administration of Venlafaxine or gabapentin on acute and chronic postmastectomy pain.
Postmastectomy pain syndrome is a neuropathic pain syndrome that is known to develop after breast surgery. Preemptive analgesia has been shown to be efficacious in reducing postoperative pain, and may be effective in reducing the incidence of certain types of neuropathic pain. We investigated the analgesic efficacy of Venlafaxine and gabapentin on acute and chronic pain associated with cancer breast surgery. ⋯ Venlafaxine 37.5 mg/d extended release or gabapentin 300 mg/d have equipotent effects (except on the first day in venlafaxine group) in reducing analgesic requirements, although gabapentin is more effective in reducing pain after movement. Venlafaxine significantly reduced the incidence of postmastectomy pain syndromes (chronic pain) 6 months in women having breast cancer surgery. Gabapentin had no effect on chronic pain except decreasing incidence of burning pain.

The use of strong opioids for treatment of noncancer chronic pain has increased. However, strong evidence for sustained pain relief and improved function is lacking. Controversy prevails, whether hormonal changes are induced by long-term treatment with opioids. The purpose of this study was to investigate the occurrence of endocrine dysfunction in chronic pain patients on long-term opioid treatment. ⋯ Long-term treatment of chronic pain with strong opioids causes side effects that can be attributed to hormonal abnormalities caused by opioid-induced inhibition of hypothalamic-pituitary function. Hormone substitution can be indicated to treat symptoms. Decreasing the opioid dose or stopping the opioid treatment can reverse endocrine dysfunction. This needs to be recognized by all practitioners treating chronic pain patients with opioids.

Randomized Controlled Trial
The effectiveness of an Acceptance and Commitment Therapy self-help intervention for chronic pain.
To evaluate the effectiveness of an Acceptance Commitment Therapy based self-help book for people with chronic pain. ⋯ These findings support the hypothesis that using the self-help book, with minimal therapist contact adds value to the lives of people who experience chronic pain.

To examine how the Adult Responses to Children's Symptoms (ARCS) does in a sample of children and adolescents with a variety of complex chronic pain conditions and to further validate the ARCS by examining associations among the subscale scores and patients' functional disability and depressive symptoms. ⋯ This study provides the first-known examination of the factor structure of the ARCS in a large sample of pediatric patients with diverse chronic pain conditions. Confirmatory factor analyses indicate that the ARCS is a valid measure for use with children and adolescents presenting to outpatient pain clinics with a variety of chronic pain complaints.
