There continues a significant debate over the best contemporary method for treating trigeminal neuralgia. Glycerol injection into the trigeminal cistern has been used in a consecutive series of 200 patients. A total of 80% of the patients have had good or excellent pain relief. ⋯ A recurrence rate of 24% has been the single largest disadvantage of the procedure. Reinjection is usually successful in treatment of recurrence. The combination of efficacy, minimal and temporary neurologic dysfunction, and low complication rate make this procedure, in our opinion, the procedure of choice for the first step, when surgical treatment is required.

Surgical indications do not forecast outcomes as well as they should. A review of the literature demonstrates a significant rate of overutilization of coronary angiography, coronary artery surgery, cardiac pacemaker insertion, upper gastrointestinal endoscopies, carotid endarterectomies, back surgery, and pain-relieving procedures. ⋯ Arguments against this approach and a plea for the development of tighter focused indications are presented. Implications for cost saving and reduction in suffering are discussed.

Biofeedback, progressive muscle training, and relaxation tape home practice were implemented in an attempt to decrease knee pain in a subject diagnosed with osteoarthritis. Pain journal data suggested that the subject's pain levels decreased significantly during training and for 2 years posttraining. ⋯ One possible explanation for these changes was the home practice of her relaxation tape, as increased practice was inversely related to decreased pain. This clinical case report provided some preliminary information on the potential efficacy of psychological procedures in osteoarthritis pain management.

Comparative Study
The subjective experience of acute pain. An assessment of the utility of 10 indices.
Sixty-nine postoperative patients indicated the severity of their pain using eight measures designed to assess pain intensity and two designed to measure pain affect. The utility and validity of the 10 measures were evaluated according to two criteria: (a) the magnitude of the relationship between each scale and a linear combination of the pain measures, and (b) relative rates of incorrect responding. ⋯ The 11-point Box Scale (BS-11) of pain intensity demonstrated the strongest relationship to a linear combination of all of the measures employed and was responded to correctly by each subject in the sample. All else being equal, these results suggest that the BS-11 scale may be the most useful clinical index of pain intensity among postoperative patients.

The efficacy of self-hypnosis in the treatment of chronic pain was evaluated using a multiple baseline design for five patients referred to the Auckland Hospital Pain Clinic. Subjects were selected for high hypnotisability using the Stanford Hypnotic Clinical Scale. Daily records of pain intensity, sleep quality, medication requirements, and self-hypnosis practice were completed. ⋯ The patients showed an increase in personal locus of control and a shift of self-concept away from physical illness on the ISCRG. The results suggest that self-hypnosis can be a highly effective technique for some patients with chronic pain but not for all. Selection criteria and clinical factors other than hypnotisability need to be considered in further research, since even highly hypnotisable subjects may derive limited benefit from self-hypnosis.
