Objective. To evaluate changes in Minnesota Multiphasic Personality Inventory (MMPI) profiles pre- and post-treatment involving intrathecal opioid therapy. Patients and Methods. ⋯ Indeed, patients with the more normal profile pretreatment did not fare as well as those with the more elevated profile. A positive change in MMPI profile from pre- to post-treatment was associated with a higher level of pain reduction. Patient selection therefore should be based not on a single test such as the MMPI, but on consistency across multiple sources of information including physical examination, complaints of pain and disability, behavioral observations, and psychological testing.

Objectives. To report complications associated with implant of the intrathecal drug delivery systems (IDDS). Patients and Methods. ⋯ Conclusion. IDDS are effective and safe devices for pain management. The complications associated with implants are mostly pharmacological and transient.

Intraspinal drug delivery systems are becoming increasingly utilized for the management of patients with pain or spasticity. Numerous potential complications associated with the use of this technology have previously been described in the literature. We have had experience with a new complication of the internal alarm being triggered by the instillation of cold solution into the pump resevoir. This new finding could have implications for patients with respect to unnecessary reevaluations of the pump, or possible premature scheduling of pump replacement surgery.

Objective. To present a novel treatment approach for intractable inguinal neuralgia utilizing percutaneous peripheral electrostimulation. Materials and Methods. ⋯ Both patients who were on disability due to inguinal pain have been able to return to full-time employment. Conclusion. These preliminary results suggest that the technique described is effective and safe, and may be cost-effective as well.

This case study describes the therapeutic result of intrathecal administration of ziconotide, a new synthetic neurotoxin derived from the venom of the Philippine marine snail, Conus Magus, to a 48-year-old male with chronic, and previously untreatable, neuropathic pain of an undeterminable etiology. The patient suffered tactile allodynia and reported his baseline pain intensity to be 80 mm on the 100 mm Visual Analog Scale for Pain Intensity. ⋯ Currently, the patient rates his pain at 16 mm and enjoys an improved quality of life. This result suggests that treatment with ziconotide may provide outstanding relief to patients with chronic pain while sparing them the unpleasant side effects associated with other treatments.
