A 21-year-old man suffered from diffuse low back pain and sciatica for 10-s periods once or twice a day over a period of 6 months. After this, pain became chronic and was resistant to conventional conservative treatment. Only acetylsalicylic acid diminished pain. ⋯ The time between onset of symptoms and final diagnosis was 18 months. Symptoms disappeared after surgery. Clinical and radiological aspects of the case are discussed.

This study assessed the prevalence rates of psychopathology in acute carpal tunnel syndrome (CTS) and acute low back pain (LBP) patients. Psychopathology was assessed with the Structured Clinical Interview for the DSM-III-R (SCID). ⋯ In regard to other types of psychopathology, such as depression, current substance abuse, and somatoform pain disorders, CTS patients had similar rates as the LBP patients. It was concluded that anxiety disorders may be a concomitant of carpal tunnel syndrome, and that treating psychological problems along with physical aspects of the syndrome may increase the patient's chance of a successful therapeutic outcome.

Patient selection for repeated spinal surgery is not uniform and must be further refined. A multidisciplinary approach with careful evaluation of physical, psychological and environmental factors is ideal. Improved imaging should delineate disorders more clearly, and advances in surgical technique may improve outcome. It is likely, however, that a number of patients will continue to require long-term pain management.

The reactivity of surface paraspinal EMG was contrasted among groups of (1) patients seeking treatment for chronic back pain, (2) nonpatients reporting chronic back pain, and (3) healthy controls. The EMG response to the personally relevant stressor (all stimuli were 1 min.) tasks was greater for the patient group relative to the other two groups. However, the patients' magnitude of response elicited by the control task was nearly equal to that of the personally relevant task, suggesting that the task demand to "describe a recent event" may be the "personally relevant" stressor component rather than the emotional valence attached to the content of that description.

Seventeen drawings of localised low-back pain were analysed by two assessors using 4 systems. Three were grid-based systems and one was by computer. The mean area or 'extent' was calculated to be 7.7%, 4.7%, 3.6% and 2.3% of the body outline using 45, 200, 560 and 61,102 section analyses, respectively. ⋯ Correlation coefficients of extent between the systems varied from 0.46 to 0.94. Correlation was highest between systems of adjacent magnitude of sections. It is concluded that grid-based assessment of small areas overestimates the actual area of pain and this may account for the lack of sensitivity to change in clinical status.
