Comparative Study
Pain relief scale is more highly correlated with numerical rating scale than with visual analogue scale in chronic pain patients.
The pain relief scale (PRS) is a method that measures the magnitude of change in pain intensity after treatment. The present study aimed to evaluate the correlation between PRS and changes in pain determined by the visual analogue scale (VAS) and numerical rating scale (NRS), to confirm the evidence supporting the use of PRS. Sixty patients with chronic spinal pain that had a VAS and NRS recorded during an initial examination were enrolled in the study. ⋯ Compared to PRS, the VAS and NRS percentile scores exhibited higher correlation coefficients than scores based on the raw data differences. Furthermore, even when converted to a percentile, the NRS%-PRS R (0.968) was higher than the VAS%-PRS R (0.904), P = 0.0001. The results indicated that using the PRS together with NRS in pain assessment increased the objectivity of the assessment compared to using only VAS or NRS, and may have offset the limitations of VAS or NRS alone.

Review Meta Analysis
The impact of genetic variation on sensitivity to opioid analgesics in patients with postoperative pain: a systematic review and meta-analysis.
Individual response to opioid analgesics varies among patients. ⋯ The results indicate that among the genetic SNPs we studied which include those affecting analgesic drug metabolism, transport of analgesic agents across the blood-brain barrier, and their activity at target receptors and ion channels and in the modulation of neurotransmitter pathways, the A118G allele variant of OPRM1 has the most potent influence on pain management of postoperative patients. Opioid receptor gene information may provide valuable information for clinicians to properly manage the analgesic use of opioids individually for better pain management.

Randomized Controlled Trial
Pulsed radiofrequency for chronic inguinal neuralgia.
Chronic inguinal neuralgia has been reported after inguinal herniorrhaphy, caesarean section, appendectomy, and trauma to the lower quadrant of the abdomen or inguinal region. ⋯ For intractable chronic inguinal pain, PRF for the dorsal root ganglion represents a promising treatment modality.

Randomized Controlled Trial Multicenter Study
Pressure pain and isometric strength of neck flexors are related in chronic tension-type headache.
In patients with chronic tension-type headache (CTTH) changes in pressure pain in the cervical region are associated with peripheral or central sensitization. It is hypothesized that an increase of isometric strength of neck flexors would lead to a decrease of pressure pain in CTTH, as an expression of reduced peripheral or central sensitization ⋯ Decrease in PPS correlates with increases in isometric strength of neck flexors in patients with CTTH in short- and long-term.

The pathological entities commonly associated with lumbosacral pain are the intervertebral discs, facet joints or surrounding muscle. However, in the absence of diagnostic confirmation of the aforementioned structures, the diagnosis may become confusing and intractable. Sacroiliac fascial lipocele (SFL), namely, pannicular hernia, could be a neglected cause. ⋯ It is important to distinguish SFL some cases with lumbosacral back pain. Detailed physical examination, superficial ultrasonography and diagnostic nerve block are extremely valuable for acquiring a precise diagnosis. Overall, when considering the clinical outcome of such cases and the foregoing benefits, percutaneous endoscopic treatment could be an efficacious alternative treatment for SFL-related lumboscral back pain.
