Despite the high prevalence of chronic multisite pain, there is little consensus on methods to characterize it. Commonly used assessments report only one dimension of pain, that is, intensity, thus ignoring the spatial aspect of pain. We developed a novel pain quantification index, the Integrated Pain Quantification Index (IPQI), on a scale of 0 to 1 that integrates multiple distinct pain measures into a single value, thus representing multidimensional pain information with a single value. ⋯ IPQI provided a single pain score for representing complex, multidimensional pain information on one scale and has implications for comparing pain populations across longitudinal clinical trials.

To determine if a history of severe episodic low back pain (LBP) correlates with positive discography. ⋯ A positive history of severe episodic LBP may be a strong indicator for a discogenic etiology.

The Importance of the Saphenous Nerve Block for Analgesia Following Major Ankle Surgery: A Randomized, Controlled, Double-Blind Study.
Major ankle surgery causes intense postoperative pain, and whereas the importance of a sciatic nerve block is well established, the clinical significance of a supplemental saphenous nerve block has never been determined in a prospective, randomized, double-blind, placebo-controlled trial. We hypothesized that a saphenous nerve block reduces the proportion of patients experiencing significant clinical pain after major ankle surgery. ⋯ This study has been registered at ClinicalTrials.gov, identifier NCT02697955.

Comparative StudySlowly Repeated Evoked Pain as a Marker of Central Sensitization in Fibromyalgia: Diagnostic Accuracy and Reliability in Comparison With Temporal Summation of Pain.
This study examined the diagnostic accuracy and test-retest reliability of a novel dynamic evoked pain protocol (slowly repeated evoked pain [SREP]) compared with temporal summation of pain (TSP), a standard index of central sensitization. ⋯ SREP seems to be a dynamic evoked pain index tapping into pain sensitization that allows for greater diagnostic accuracy in identifying FM patients compared with a standard TSP protocol. Further research is needed to study mechanisms underlying SREP and the potential utility of adding SREP to standard pain evaluation protocols.

Comparative Study
Patient controlled analgesia: The impact of an 8 versus 10 minute lockout interval in postoperative patients.
The purpose of this study was to compare the level of pain control achieved with 8 versus 10 minute lockout intervals in adult patients who received patient controlled analgesia (PCA) within 24 hours of surgery. There was no difference in pain in the first 72 hours between the 8 minute and 10 minutes group. Additionally, there was no difference in time to first PCA regimen change or a composite outcome of adverse events.
