The objective of this study was to examine the effects of rofecoxib, meloxicam, both cyclooxygenase-2 (COX-2) inhibitors and aminoguanidine hydrochloride, an inducible nitric oxide synthase (iNOS) inhibitor and their combinations in neuropathic pain in rats. ⋯ Co-administration of meloxicam and rofecoxib with aminoguanidine hydrochloride may be an alternative approach for the treatment of neuropathic pain.

Chronic musculoskeletal pain in patients with the chronic fatigue syndrome: a systematic review.
In addition to debilitating fatigue the majority of patients with chronic fatigue syndrome (CFS) experience chronic widespread pain. ⋯ The results from the systematic review highlight the clinical importance of chronic pain in CFS, but only few studies addressing the aetiology or treatment of chronic pain in CFS are currently available.

Randomized Controlled Trial Comparative Study
Effect of hypnotic suggestion on fibromyalgic pain: comparison between hypnosis and relaxation.
The main aims of this experimental study are: (1) to compare the relative effects of analgesia suggestions and relaxation suggestions on clinical pain, and (2) to compare the relative effect of relaxation suggestions when they are presented as "hypnosis" and as "relaxation training". Forty-five patients with fibromyalgia were randomly assigned to one of the following experimental conditions: (a) hypnosis with relaxation suggestions; (b) hypnosis with analgesia suggestions; (c) relaxation. ⋯ The results showed: (1) that hypnosis followed by analgesia suggestions has a greater effect on the intensity of pain and on the sensory dimension of pain than hypnosis followed by relaxation suggestions; (2) that the effect of hypnosis followed by relaxation suggestions is not greater than relaxation. We discuss the implications of the study on our understanding of the importance of suggestions used in hypnosis and of the differences and similarities between hypnotic relaxation and relaxation training.

Central sensitisation due to visceral pancreatic nociceptive input may play an important role in chronic pancreatitis pain. Using quantitative sensory testing (QST), this first study investigates whether thoracoscopic splanchnic denervation (TSD), performed to reduce nociceptive visceral input, affects central sensitisation in chronic pancreatitis patients. ⋯ TSD for chronic pancreatitis pain resulted in fewer patients on opioids and overall increases in pain thresholds. Our results suggest that TSD for reducing visceral nociceptive input may be effective in reducing resulting central sensitisation. Although patients benefiting from TSD consume less opioids preoperatively, we were unable to clearly link treatment success with specific perioperative patterns of neuroplasticity such as the presence or absence of hyperalgesia.
