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.

Randomized Controlled Trial Clinical Trial
Global and specific behavioral measures of pain in children with cerebral palsy.
The aim of this research was to validate global and behavioral observation methods for measuring pain in children with cerebral palsy (CP). ⋯ These findings support the hypothesis that children with CP express discernible pain behaviors regardless of cognitive or language ability. These results contribute to multidimensional assessment of pain in children with neurologic impairment.

Randomized Controlled Trial Clinical Trial
Patterns of pain variation related to myogenous temporomandibular disorders.
Myogenous temporomandibular disorders are characterized by jaw muscle pain. The aims were: 1) to characterize this pain generally in terms of intensity, frequency, duration, and behavior across a period of 2 weeks; 2) to identify main intraday pain patterns and to examine whether subgroups of patients in this respect differed in clinical, demographic, pain and sleep variables, psychosocial factors, and use of medication; and 3) to investigate some possible interday trends of pain intensity at a group level. ⋯ Two main daily pain patterns occur in patients with myogenous temporomandibular disorders (79%: maximal pain late in the day; 21%: early in the day), which might be related to differences in processes that influence pain sensitivity and patterns of jaw muscle activation. The interday similarities in pain level suggest that a sustained influence of counseling after the intake or an influence of a common behavioral pattern with a cycle duration of a week are not involved.

Clinical Trial Controlled Clinical Trial
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.

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.
