ReviewPost Dural Puncture Headache, Managed with Epidural Blood Patch, Is Associated with Subsequent Chronic Low Back Pain in Patients: a Pilot Study.
Post dural puncture headache (PDPH) is a relatively common complication which may occur in the setting of inadvertent dural puncture (DP) during labor epidural analgesia and during intentional DP during spinal anesthetic placement or diagnostic lumbar puncture. Few publications have established the long-term safety of an epidural blood patch (EBP) for the treatment of a PDPH. ⋯ The aim of this pilot study was to examine the association of chronic low back pain (LBP) in patients who experienced a PDPH following labor analgesia and were treated with an EBP. A total of 146 patients were contacted and completed a survey questionnaire via telephone. The EBP group was found to be more likely to have chronic LBP (percentage difference 20% [95% CI 6-33%], RR 2.6 [95% CI 1.3-5.2]) and also LBP < 6 (percentage difference 24% [95% CI 9- 37%], RR 2.3 [95% CI 1.3-4.1]). There were no significant differences in the severity and descriptive qualities of pain between the EBP and non-EBP groups. Our findings suggest that PDPH treated with an EBP is associated with an increased prevalence of subsequent low back pain in parturients. The findings of this pilot study should spur further prospective research into identifying potential associations between DP, EBP, and chronic low back pain.

Randomized Controlled Trial
Endoscopic rhizotomy for chronic lumbar zygapophysial joint pain.
Chronic lumbar zygapophysial joint pain is a common cause of chronic low back pain. Percutaneous radiofrequency ablation (RFA) is one of the effective management options; however, the results from the traditional RFA need to be improved in certain cases. The aim of this study is to investigate the effect of percutaneous radiofrequency ablation under endoscopic guidance (ERFA) for chronic low back pain secondary to facet joint arthritis. ⋯ ERFA may achieve more accurate and definite denervation on the nerves, which leads to longer lasting pain relief.

Rescue medication is commonly offered to participants in placebo-controlled trials of analgesic drugs. The use of pain medication in addition to the placebo or experimental drug may complicate the interpretation of effects and tolerability, but this issue has received little methodological attention. This study examined the handling and reporting of rescue and concomitant analgesic use in trials of pharmacotherapy for neuropathic pain and low back pain. ⋯ More than one-third of the trials permitting rescue medication did not report the actual rescue drug consumption, and over half of the trials allowing concomitant analgesics did not report whether intake changed during the trial. Only 22 (19%) of the trials permitting rescue medication included complete information about whether rescue medication was used as an outcome, specified the drugs used, specified how consumption was assessed and measured, and reported and analyzed the use of rescue medication in each trial arm. Our findings suggest that poorly described procedures and incomplete reporting are likely to hinder the interpretation, critical appraisal, and replication of trial results.

Low back pain secondary to discopathy is a common pain disorder. Multiple minimally invasive therapeutic modalities have been proposed; however, to date no study has compared percutaneous laser disc decompression (PLDD) with intradiscal injection of radiopaque gelified ethanol (DiscoGel®). We are introducing the first study on patient-reported outcomes of DiscoGel® vs. PLDD for radiculopathy. ⋯ Both techniques were equivalent in pain reduction but DiscoGel® had a greater effect on decreasing disability after 12 months, although the rate of progression to secondary treatments and/or surgery was almost equal in the two groups.
