The analysis of patient data concerning psychological structure and functioning produced an instrument to determine whether a neurostimulator ought to be implanted or not. ⋯ The correlation between the I.F. and the E.F. was calculated for the 40 patients by the Spearman correlation test. A coefficient value of 0.8083 (p = 0.000) was found, indicating the existence of a very close correlation between the predictive I.F. and the E.F. The indication scale appears to be a useful instrument for clinical psychologists to predict the success rate of a spinal cord stimulator in this group of patients.

Inadequate assessment of pain in premature infants is a persistent clinical problem. The objective of this research was to develop and validate a measure for assessing pain in premature infants that could be used by both clinicians and researchers. ⋯ The PIPP is a newly developed pain assessment measure for premature infants with beginning content and construct validity. The practicality and feasibility for using the PIPP in clinical practice will be determined in prospective research in the clinical setting.

Randomized Controlled Trial Clinical Trial
Acute pain after thoracic surgery predicts long-term post-thoracotomy pain.
Long-term pain is a common sequela of thoracotomy, occurring in approximately 50% of patients 2 years after thoracic surgery. Despite this alarming statistic, little is known about the factors responsible for the transition of acute to chronic pain. The aim of the present study is to identify predictors of long-term post-thoracotomy pain. ⋯ Aggressive management of early postoperative pain may reduce the likelihood of long-term post-thoracotomy pain.

Case Reports
Psoas sheath chemical neurolysis for management of intractable leg pain from metastatic liposarcoma.
A 56-year-old man with widely metastatic liposarcoma, after left Tower extremity amputation, complained of severe right lower extremity pain. Trials of systemic opioids had resulted in poor pain control while introducing intolerable dose-limiting side effects. ⋯ Initial inpatient management consisted of a lumbar epidural infusion of a dilute local anesthetic and preservative-free morphine. This provided satisfactory relief but was discontinued because of recrudescence of phantom limb pain. A lumbar epidural infusion of preservative-free morphine sulfate was associated with poor pain relief, central nervous system (CNS) side effects, and severe urinary retention resulting in acute renal failure. A repeated trial of parental opioids provided marginal pain relief with persistent CNS side effects. Chemical neurolysis of the lumbar plexus was performed with 10 ml of 10% aqueous phenol injected into the psoas muscle sheath. The pain gradually resolved over a 2-day period without apparent side effects. Motor function was preserved, pain was resolved, and as systemic opioids were reduced, cognitive function and overall well-being were improved.

Case Reports Clinical Trial
Gabapentin adjunctive therapy in neuropathic pain states.
This is a report of a trial of the new antiepileptic agent gabapentin in patients with intractable neuropathic pain. ⋯ Gabapentin provides analgesic activity for patients with neuropathic pain and has the advantage of a low side effect profile and drug toxicity.
