Comparative Study
A simultaneous comparison of three neonatal pain scales during common NICU procedures.
This study evaluated neonatal pain scales during procedures commonly performed in a neonatal intensive care unit. ⋯ The pain scale scores identify changes in an infant's behavior/physiologic state. It is unclear whether these changes are totally "pain specific." In comparing the three scales, the SUN overall was a preferable tool because of its ease of use, scale symmetry, and scoring consistency.

A study was conducted to assess a variety of treatment outcomes in long-term users of transcutaneous electrical nerve stimulation (TENS) who suffer from chronic pain. Key components of the study examined the effects of long-term TENS therapy on pain-related medications and physical/occupational therapy (PT/OT) use. ⋯ Long-term use of TENS is associated with a significant reduction in the utilization of pain medication and PT/OT. In this study population, cost simulations of medication and PT/OT indicate that with long-term TENS use, costs can be reduced up to 55% for medications and up to 69% for PT/OT. The potential for TENS associated improvement, combined with reduced medication-related complications and costs, are important points that clinicians should consider when constructing a treatment plan for chronic pain patients. Finally, cost simulation techniques provide a useful tool for assessing outcomes in pain treatment and research.

This cross-sectional study evaluated the extent to which relations between employment status and emotional distress are mediated by pain-related and psychosocial measures among employed and unemployed persons with chronic pain. ⋯ Findings suggest that pain severity and the quality of specific experiences related to being employed or unemployed as opposed to employment status per se correspond directly to levels of emotional distress reported by some persons with chronic pain.

To compare efficacies, failure rates, and technical complication rates of intraspinal treatments in patients with "refractory" nonmalignant pain conditions in relation to the approach (epidural/intrathecal), the drug (opioid/opioid-bupivacaine or bupivacaine), and the type of system used (externalized/internalized). In these comparisons, recent data from a companion paper (Nitescu et al., Clin J Pain 1998;14:17-28) were used as a reference to be compared with data from a literature review of different intraspinal treatment modalities in nonmalignant pain. ⋯ (a) The intrathecal approach, compared with the epidural approach, was associated with higher rates of satisfactory pain relief for both externalized (86/90, 95% vs. 17/40, 42.5%, p < .0001) and internalized (295/336, 89% vs. 33/56, 59%, p < .0001) catheters; higher rates of treatment failures with externalized epidural catheters than with internalized intrathecal catheters (24/47, 51%, vs. 36/338, 11%, p < .0001); lower rates of treatment failures with internalized intrathecal catheters than with internalized epidural catheters (36/338, 11% vs. 29/76, 38%, p < .0001); higher rates of system replacement with internalized epidural catheters than with internalized intrathecal catheters (23/32, 72% vs. 6/49, 12%, p < .0001; higher rates of system removal with internalized epidural catheters than with internalized intrathecal catheters (22/49, 45% vs. 5/49, 10%, p < .001); higher rates of catheter-related complications with epidural than with intrathecal catheters (dislodgement 13/126, approximately 10% vs. 6/150, 4%, p < .05; leakage 5/51, approximately 10% vs. 1/116, 0.9%, p < .05; obstruction 2

Clinical Trial Controlled Clinical Trial
Effect of carbamazepine on pain scores of unipolar depressed patients with chronic pain: a trial of off-on-off-on design.
The purpose of this study was to evaluate the effect of carbamazepine on chronic pain in patients with major depression. ⋯ These results may indicate that carbamazepine has both an antidepressive and an analgesic action in depressed patients. Thus, carbamazepine may offer an acceptable therapeutic option in depressed patients with chronic pain that is unresponsive to antidepressants. Alternatively, these results may indicate that carbamazepine appears to help depression in this group of pain patients because of its analgesic effect (i.e., helps depression as a result of helping pain or vice versa).
