Randomized Controlled Trial Clinical Trial
The effects of cognitive-behavioral and physical therapy preventive interventions on pain-related sick leave: a randomized controlled trial.
Recent recommendations suggest that reassuring patients with an acute bout of low back pain and encouraging a return to normal activities may be helpful in preventing the development of chronic disability. There is also a question as to whether psychologic or physical therapy interventions actually add anything to such reassurance and advice in terms of preventing chronicity. This study aimed to ascertain the preventive effects on future sick leave and health-care utilization of adding on a cognitive-behavioral group intervention or a cognitive-behavioral group intervention and preventive physical therapy (focused on activity and exercise) relative to a minimal treatment group (examination, reassurance, and activity advice). ⋯ Taken as a whole, this study shows that adding cognitive-behavioral intervention and cognitive-behavioral intervention and preventive physical therapy can enhance the prevention of long-term disability. There was no substantial difference in the results between the cognitive-behavioral intervention group and cognitive-behavioral intervention and preventive physical therapy group.

The effectiveness of multidisciplinary rehabilitation in the treatment of fibromyalgia: a randomized controlled trial.
To assess the effectiveness of multidisciplinary rehabilitation in the treatment of fibromyalgia in comparison to standard medical care. ⋯ Positive health-related outcomes in this mostly unresponsive condition can be obtained with a low-cost, group multidisciplinary intervention in a community-based, nonclinical setting.

Sex differences in delayed onset muscle pain.
In contrast to the research using typical experimental pain stimuli, there is no consensus that women are more sensitive to delayed onset muscle pain than men. The purpose of this study was to examine sex differences in delayed onset muscle pain with use of a quantified stimulus intensity and multidimensional and valid pain measures. ⋯ The absence of higher muscle pain ratings in women than men in this investigation resembles a review of the delayed onset muscle soreness and pain literature. However, the findings contradict a few other acute muscle pain investigations, in which actual muscle tissue damage was not induced by eccentric contractions. Additional research is required to identify the parameters that influence the detection of sex differences.

Case Reports
The fasciitis-panniculitis syndrome presenting as complex regional pain syndrome type 1: report of a case.
A 28-year-old man presented with a clinical picture suggestive of complex regional pain syndrome type I following a blow to the thenar eminence and thumb. Symptoms, including swelling of the hand and distal forearm, progressed until an amputation was carried out to rid the patient of an unendurable painful and nonfunctioning wrist and hand. The histologic evaluation of the amputation specimen showed: 1) dermal edema, perivascular dermatitis, and epidermal hyperkeratosis; 2) subcutaneous chronic inflammation with subtotal replacement of the adipose lobules by fibrous tissue associated with thickening of the muscular fascia, implying the fasciitis-panniculitis reaction pattern; 3) atrophy, degeneration, necrosis, and focal calcifications of the skeletal muscles; 4) phlebosclerosis, phlebectasias and lymphocytic arteritis; and 5) increased cortical porosity of the bones. It seems that the pathogenetic process underlying the fasciitis-panniculitis syndrome may rarely manifest as a complex regional pain syndrome-like disorder.

Widespread sensory hypersensitivity is a feature of chronic whiplash-associated disorder but not chronic idiopathic neck pain.
To investigate sensory changes present in patients with chronic whiplash-associated disorders and chronic idiopathic neck pain using a variety of quantitative sensory tests to better understand the pain processing mechanisms underlying persistent symptoms. ⋯ Both chronic whiplash-associated disorders and idiopathic neck pain groups were characterized by mechanical hyperalgesia over the cervical spine. Whiplash subjects showed additional widespread hypersensitivity to mechanical pressure and thermal stimuli, which was independent of state anxiety and may represent changes in central pain processing mechanisms. This may have implications for future treatment approaches.
