Randomized Controlled Trial
Concordant pressure paresthesia during interlaminar lumbar epidural steroid injections correlates with pain relief in patients with unilateral radicular pain.
Transforaminal and interlaminar epidural steroid injections are commonly used interventional pain management procedures in the treatment of radicular low back pain. Even though several studies have shown that transforaminal injections provide enhanced short-term outcomes in patients with radicular and low back pain, they have also been associated with a higher incidence of unintentional intravascular injection and often dire consequences than have interlaminar injections. ⋯ This study showed that the lateral parasagittal interlaminar approach was more effective than the midline interlaminar approach in targeting low back pain with unilateral radicular pain secondary to degenerative lumbar disc disease. It also showed that pressure paresthesia occurring ipsilaterally during an LESI correlates with pain relief and may therefore be used as a prognostic factor.

Randomized Controlled Trial
Dual reuptake inhibitor milnacipran and spinal pain pathways in fibromyalgia patients: a randomized, double-blind, placebo-controlled trial.
Investigations based on quantitative sensory testing have consistently shown evidence of allodynia in fibromyalgia syndrome (FMS) patients involving both the spinal and supraspinal pain regulatory systems. Functional imaging studies have demonstrated enhanced neural activities in pain-related brain areas as well as impairment of pain inhibition in the descending nociceptive regulatory system. A higher state of excitability of spinal nociceptive neurons as evidenced by lowered nociceptive flexion reflex R-III (NFR) threshold was reported for FMS patients. The NFR procedure has been shown to be a valuable tool to evaluate pharmacologically active therapeutic agents at the spinal level. ⋯ Milnacipran has a predominantly supraspinal analgesic effect as evidenced by the significant clinical benefits and the absence of changes in the nociceptive spinal reflex threshold. Higher dose was associated with higher pain reduction. Reported analgesia was independent of patients' emotional status.

Randomized Controlled Trial
A randomized, double-blind, active control trial of fluoroscopic cervical interlaminar epidural injections in chronic pain of cervical disc herniation: results of a 2-year follow-up.
A recent evaluation of the state of U.S. health from 1990 to 2010 placed neck pain as the fourth condition leading to disability, with low back pain being the number one. Multiple treatment modalities have been described in managing neck and upper extremity pain secondary to cervical disc herniation after the failure of conservative management. The treatment modalities for chronic persistent pain of cervical disc herniation include surgery and epidural injections. The growth of interventional techniques in managing chronic spinal pain in recent years has been enormous. Evidence for the efficacy of cervical interlaminar epidural injections, however, continues to be debated, despite positive evidence derived from controlled randomized trials and systematic reviews. ⋯ Cervical epidural injections with local anesthetic with or without steroids.

The genetic influence of Val158Met polymorphisms, one of the potential genetic determinants for nociceptive processing, has not been previously investigated in women with carpal tunnel syndrome (CTS). ⋯ Current results indicated that the Val158Met polymorphism seems not to be a risk factor for the development of CTS; however, it was associated with increased perception of pain and higher disability scores.

The heterogeneity of patients with osteoporotic vertebral compression fractures (VCF) necessitates a tailored approach of balancing the benefits and limitations of available treatments. Current guidelines are divergent, sometimes contradictory, and often insufficiently detailed to guide practice decisions. ⋯ The panel results may help to support treatment choice in the heterogeneous population of patients with osteoporotic VCF.
