Diagnostic epidural blocks were performed on 27 chronic pain patients sequentially using saline, fentanyl, and lidocaine solution. The patients were divided into one of four groups based on their response to the epidural solutions: placebo response group--pain relief with placebo solutions; fentanyl response group--pain relief with epidural fentanyl; lidocaine response group (LRG)--pain relief with lidocaine but not fentanyl; and no response group--no pain relief with any of the solutions used. The four groups were compared on the basis of age, sex, site of pain, duration of pain, narcotic use, pain assessment index, and workmen's compensation claims. ⋯ On the basis of the information gathered, it was theorized that, despite their response to epidural lidocaine, LRG patients may actually be a group of operant pain patients. Their failure to receive analgesia from epidural fentanyl may be a learned response such that they associate any sensory input from the affected area as painful. If follow-up studies support these findings, then the diagnostic opioid technique may be a more sensitive tool in diagnosing chronic pain.

In order to investigate the efficacy of repeated irradiation of low-power helium-neon laser in pain relief, we irradiated 36 outpatients suffering from postherpetic neuralgia. Each patient underwent 20 trials of irradiation on several points around the painful area at a frequency of 2 or 3 times a week. The efficacy of the laser at the end of 20 trials was noticed on 88.9%, and the degree of pain relief was 55.3%, which correlated with the number of trials. These results suggest that the irradiation of He-Ne laser is an effective and safe treatment for postherpetic neuralgia.

To control costs, the University of Tennessee Center for Pain Management added an ambulatory pain rehabilitation program to its existing inpatient hospitalization program. The impact of this program was assessed by comparing the first 25 patients treated in 1985 (prior to the introduction of outpatient management) with the first 25 patients treated in 1987 (after outpatient management was established). ⋯ Hospital charges were the greatest single cost factor in 1985 ($321,500) but were only $61,000 in 1987. Success rates as measured by a return to previous employment were not significantly changed (13 of 25 returned to work in 1985, and 11 of 25 returned to work in 1987).

Fifty-one subjects with chronic pain were assessed for couple functioning utilizing the Family Adaptability and Cohesion Evaluation Scale. In addition, they completed the Beck Depression Inventory. ⋯ Depressed subjects reported a higher level of couple dysfunction than the nondepressed group. Duration of pain was found to be unrelated to family adaptability, family cohesion, and family stability.

The purpose of this study was to assess the impact of outpatient group treatment for chronic pain patients and their spouses on psychological symptomatology, marital adjustment, and locus of control. There was a significant improvement in mean scores on four of the seven measures pre- and post-treatment. ⋯ It also supports other findings for the effectiveness of brief group therapy programs for chronic pain patients. Although this study has several limitations the results warrant further investigation using control groups and a larger sample size.
