Transforaminal epidural steroid injection (TFESI) is widely used to manage lumbosacral radicular pain due to herniated lumbar disc (HLD). ⋯ Our findings provide useful information to clinicians managing radicular pain due to HLD.

Studies with nonsignificant results are less likely to be published or published in lower impact factor journals. To determine whether a similar phenomenon occurs in pain literature, we explored impact factor bias in peer-reviewed pain journals. ⋯ After adjusting for study factors associated with publication, there is no evidence of impact factor bias within the pain literature. The lack of impact factor bias in the pain literature is a positive finding for the field and should benefit scientific development and the clinical care of patients.

Posterior Reversible Encephalopathy Syndrome (PRES) After Caudal Epidural Steroid Injection: a Case Report.
Caudal epidural injections are easy, effective, and safe methods and are good options for patients with low back pain and radicular lower extremity pain. Although various complications related to the technique of the procedure or the drugs used in the procedure have been described, Posterior Reversible Encephalopathy Syndrome (PRES) has not yet been defined for this intervention. ⋯ Although PRES is rarely reported, it should be kept in mind that it is a complication that can develop after caudal epidural steroid injection.

Post-herpetic neuralgia is a chronic neuropathic pain disorder that is the sequela of the varicella zoster virus reactivation in the dorsal root ganglion. A variety of treatment modalities have been implemented, but pharmacologic treatments are often limited due to side effects and interventional procedures have yielded mixed results without promising long-term benefits being consistently seen. A dorsal root ganglion stimulator for treatment of post-herpetic neuralgia is a novel treatment option as it is able to specifically target the area affected. We present 3 patients who underwent implantation of permanent dorsal root ganglion stimulators and had a greater than 50% decrease in scoring on numerical rating scale (NRS) up to 18 months post-procedure and significantly reduced analgesic requirements.
