Several studies in recent years have confirmed that the direct application of pulsed radiofrequency (PRF) on peripheral nerve compression points can alleviate hyperalgesia in animal models of neuropathic pain (NP). However, the mechanism underlying the treatment of peripheral nerves by PRF is unclear. ⋯ Pulsed radiofrequency, chronic constriction injury, sciatic nerve, 50% paw withdrawal threshold, thermal withdrawal latency, glia cell line-derived neurotrophic factor, reverse transcription-polymerase chain reaction, enzyme-linked immunosorbent assay.

Observational Study
Outcome of Transforaminal Epidural Steroid Injection According to the Severity of Lumbar Foraminal Spinal Stenosis.
Lumbar foraminal spinal stenosis (LFSS) is a common cause of radicular pain in the lower extremities. Transforaminal epidural steroid injection (TFESI) is being used widely for controlling radicular pain induced by LFSS. The efficacy of TFESI has been demonstrated in previous studies. However, no study has evaluated the outcome of TFESI according to the severity of LFSS. ⋯ Lumbar foraminal spinal stenosis, transforaminal epidural steroid injection, disease severity, magnetic resonance imaging, numeric rating scale, corticosteroids.

Randomized Controlled Trial
Reducing Radiation Exposure in Lumbar Transforaminal Epidural Steroid Injections with Pulsed Fluoroscopy: A Randomized, Double-blind, Controlled Clinical Trial.
Fluoroscopy-guided lumbar transforaminal epidural steroid injections (L-TFESI) result in radiation exposure that carries risks to patients, physicians, and procedural staff. ⋯ Radiation, epidural, fluoroscopy, injection, exposure, pulse.
