It is generally well established that catastrophizing exerts a potent influence on individuals' experience of pain and accompanying emotional distress. Further, preliminary evidence has shown that meaningful differences among various pain relevant outcomes (e.g., pain ratings, endogenous pain inhibitory processes) can be attributed to individuals' ethnic background. The mechanisms that might explain ethnic differences in pain outcomes are unclear, and it remains to be fully established whether the relation between ethnicity and pain response may be indirectly affected by pain catastrophizing. ⋯ To better explicate our findings, we described the context in which these findings occurred following a "who, what, where, when, and why" approach. This approach provides an efficient description of how our findings align with previous research, while identifying future research that should clarify the theoretical underpinnings of catastrophizing and pain and also inform clinical intervention.

The objective of this study was to report clinical spectrum of central post stroke pain (CPSP) and correlate these with magnetic resonance imaging (MRI) and single photon emission computed tomography (SPECT) findings. ⋯ The QST findings in patients with CPSP were similar in patients with thalami and extrathalamic lesions. SPECT and MRI findings were also not different in CPSP patients with and without allodynia.

Randomized Controlled Trial
Does intrathecal morphine sulfate provide preemptive analgesia for patients undergoing stapled hemorrhoidopexy?
Surgical excision of hemorrhoids is characterized by a prolonged and painful postoperative course. This double-blind, randomized, prospective, controlled trial was conducted to determine if morphine sulfate provides additional pain relief after stapled hemorrhoidopexy when added to a standard lidocaine spinal anesthetic. It was hypothesized that the addition of morphine sulfate to a spinal anesthetic would decrease postoperative pain. ⋯ This study provides evidence that intrathecal morphine sulfate does not significantly alter postoperative pain, narcotic use, or well-being when used as preemptive analgesia for patients undergoing stapled hemorrhoidopexy.

To evaluate the analgesic, physical, and psychological outcomes of percutaneous radiofrequency neurotomy for persistent zygapophysial and sacroiliac joint pain in a community setting. ⋯ Neurotomy of the cervical, thoracic, lumbar, and sacroiliac joints were uniformly successful with 72% recipients obtaining an average of 86% reduction in pain for a period of 12 months.

There are several types of lumbar stenosis, such as central, lateral recess, foraminal. The symptoms of lumbar stenosis are neurogenic claudication, numbness, tingling, etc. The treatment modality is medication, physical therapy, intervention, and surgery. The epidural steroid injection has been used for treatment of low back pain/radiculopathy. However, we could not predict what percent had pain relief after epidural steroid injection. The purpose of this study was to evaluate the usefulness of high sensitivity C-reactive protein (hsCRP) as a marker for predicting the efficacy of lumbar transforaminal epidural steroid injection. ⋯ The results suggest that there was no correlation between pretreat hsCRP and posttreat VAS. Therefore, hsCRP may not be useful as predictor of response to TFESI in patients with spinal stenosis.
