This study was designed to evaluate the psychological status of 50 individuals without chronic pain and without psychotherapeutic drug therapy, Group I, the control group; and Group II, a chronic pain group with 100 chronic pain patients. All the participants were tested utilizing Millon Clinical Multiaxial Inventory III (MCMI-III). Results were analyzed and compared for various clinical personality patterns, including personality traits and personality disorders; severe personality pathology for schizotypal, borderline and paranoid personality pathology; and multiple clinical syndromes, including generalized anxiety disorder, somatization disorder, major depression, bipolar manic disorder and dysthymic disorder, etc. ⋯ The prevalence of psychological disorders in the control group was 24%, compared to 55% in chronic pain group. In conclusion, this evaluation showed that clinical personality patterns are present in both groups of patients. Psychological abnormalities such as generalized anxiety disorder, somatization disorder, and major depression are commonly seen in chronic pain patients.

Postherpetic neuralgia (PHN) is a common cause of chronic pain in the elderly. Opioids and adjunctive analgesics such as antidepressants and anticonvulsants effectively reduce discomfort in many patients, while others have pain that remains resistant to all forms of therapy. ⋯ Peripheral nerve stimulation has been described for such problems as chronic regional pain syndrome, but to date has not been reported for cranial nerve syndromes. This article describes the cases in which an 86-year-old man and a 76-year-old woman with intractable PHN of greater than 6 and 4 years, respectively, were effectively treated with peripheral nerve stimulation of the ophthalmic division of the trigeminal nerve.

Chronic low back pain secondary to involvement of the facet joints is a common problem. Facet joints have been recognized as potential sources of back pain since 1911. Multiple authors have described distributions of pain patterns of facet joint pain. ⋯ Multiple studies utilizing controlled diagnostic blocks have established the prevalence of lumbar facet joint involvement in patients with chronic low back pain, as ranging from 15% to 52%, based on type of population and setting studied. Long-term therapeutic benefit has been reported from three types of interventions in managing lumbar facet joint pain, including intraarticular injections, medial branch blocks and neurolysis of medial branches. This review will discuss chronic low back of facet joint origin and covers anatomy, pathophysiology, diagnosis, and various aspects related to treatment, including clinical effectiveness, cost effectiveness, technical aspects and complications.

The prevalence of persistent low back pain secondary to involvement of lumbosacral facet joints has been described in controlled studies as varying from 15% to 52% based on types of population and settings studied. Previous studies have shown variances in elderly populations, and postlumbar laminectomy patients. But no variations were observed in obese patients or patients with somatization disorder. ⋯ The prevalence of facet joint pain in men was 38% (95% CI, 29% to 47%) compared to 43% (95% CI, 36% to 50%) in women; 43% (95% CI, 33% to 53%) in non-smokers, compared to 41% (95% CI, 30% to 52%) in heavy smokers; and 28% (95% CI, 18% to 38%) in occupational injury patients compared to 44% (95% CI, 36% to 52%) with a history of gradual onset. False-positive rates varied from 28% to 46%. In conclusion, based on the results of this evaluation, women and men, smokers and nonsmokers suffer with similar prevalence rates of facet joint pain in chronic low back pain; whereas occupational injury patients suffer with lesser prevalence (28%) compared to patients with gradual onset (44%) of low back pain.

The aim of this work is to assess quality of treatment and to monitor drawbacks of SCS implantation systems through a National Observational Center. Data were obtained through a questionnaire sent by post or via telephone to each patient. All patients were affected by chronic-'vascular' and "neuropathic" pain. ⋯ We conclude that the methodology used is consistent with that of previous studies on nonmalignant chronic pain. The data obtained also reveal implantation hardware reliability, regardless of clinical outcome. A low percentage of complications and a high degree of patient satisfaction are also to be stressed.
