A study was conducted to determine symptom report patterns in a heterogenous population of orofacial pain patients and to evaluate how symptom patterns relate to various dimensions of the human pain experience. Results indicated that symptoms frequently associated with chronic orofacial pain disorders can be described by four indices related to the temporomandibular joint (TMJ) and its movement; discomfort of and parafunctional activities related to the masticatory muscles; interference of pain with activities of daily living; and presence of orofacial pain unrelated to myogeneous or arthrogenous TMJ disorders. Of these four symptom indices, only the pain interference (symptom) index was related to clinical pain and illness behavior. ⋯ Two of the indices were influenced by diagnosis. Biomechanical symptoms and parafunctional activities appear to be insignificantly related to perceived pain intensity, pain responsiveness, illness behavior, or personality, but are related to diagnosis. The results indicated that relatively simple symptom checklists have potential utility in screening orofacial pain patients and in evaluation of treatment outcome.

Although convergent lines of evidence indicate that one can expect a high rate of suicide completion for chronic pain patients, this problem has not previously been investigated. Follow-up data from our pain center revealed three chronic pain patients (two men and one woman) who completed suicide. These three cases are presented. ⋯ Calculation of the 95% confidence interval and comparison of these suicide rates to the general population of the United States using the Z statistic indicated that all chronic pain patient suicide rates were significantly greater than that of the general population. White men, white women, and white worker compensation men with chronic pain in the age range of 35-64 years are twice, three, and three times as likely, respectively, as their counterparts in the general population to die by suicide. Although no firm conclusions can be drawn because of the small suicide sample, these case reports indicate a need for further studies of chronic pain patient suicide rates at other pain centers.

Sixty-nine patients undergoing spinal cord stimulation (SCS) were studied for a period of up to 8 years. Indications, implantation techniques, and stimulation systems are presented in this article. Pain-suppressor effects of SCS are reviewed, assessing the clinical efficacy over time as well as complications with the stimulation device. ⋯ Decrease of the efficacy of pain alleviation occurs during the first 3 years after implantation. Most failures are noted in patients presenting with failed back surgery. This study also demonstrates that SCS systems should offer the capability of both monopolar and bipolar stimulation modes by the use of multipolar electrodes.

Acute and chronic neck pain and headaches are a major medical, industrial, and financial problem. In many cases, the pathophysiology is unknown, and the disability is often greatly in excess of the apparent tissue pathology and physiological impairment. Diagnosis and management of neck pain and cervicogenic headache calls for a rational and comprehensive approach. Many cases will have no identifiable pathology, and the pain and disability will continue despite the best efforts of all concerned.
