Discogenic pain is recognized as the most important and most common cause of low back pain (LBP). Intradiscal pulsed radiofrequency (ID-PRF) is used for the treatment of chronic discogenic pain. ⋯ ID-PRF was shown to be effective for the treatment of discogenic LBP regardless of duration of ID-PRF application (7 vs. 15 minutes).

Clinical Trial
Computed Tomography-Guided Percutaneous Coblation of the Thoracic Nerve Root for Treatment of Postherpetic Neuralgia.
Postherpetic neuralgia (PHN) is one of the most intractable pain disorders and often does not respond to medication, physical, and interventional procedures. Coblation technology has been demonstrated to have potential for neuralgia, but there are rare reports of the efficacy and security of coblation for PHN. The thoracic segment is the most common predilection part of PHN, so we conducted this long-term study to investigate the results of coblation for the treatment of thoracic PHN. ⋯ CT-guided percutaneous thoracic nerve root coblation is an effective and safe method for the treatment of thoracic PHN, and the procedure can also significantly improve the QoL in patients with PHN.

Radiofrequency ablation (RFA) of the medial branches of the dorsal rami has been reported to relieve facet joint-related back pain for 6 months to 1 year in 60% of patients. Although providing benefit in a significant proportion of patients, there remains a group of patients who do not experience any pain relief from RFA or experience only benefit from the ablation for a short period. Failure of RFA has been attributed to technical failure of coagulating the nerve or coagulation of a minimal section of the nerve, allowing for early reinnervation. Increasing the success rate and duration of relief may require techniques that increase the likelihood of successful nerve ablation over a relevant distance by maximizing lesion size. ⋯ The detailed two-needle approach to lumbar RF medial branch denervation appears to be promising in terms of projected treatment success by coagulating a large volume of tissue, in a cost- and time-efficient manner.

Observational Study
8% Capsaicin Patch in Treatment of Peripheral Neuropathic Pain.
Neuropathic pain is a complex condition that is difficult to control and has a high impact on quality of life. 8% Capsaicin patch can be a therapeutic strategy in the treatment of peripheral neuropathic pain. ⋯ Treatment of peripheral neuropathic pain with 8% capsaicin patch seem to be effective in the short and medium term, both in decreasing pain intensity and in reducing the painful area. Its application is tolerated by most patients.

Observational Study
Observational Study to Evaluate the Effect of Epidural Steroid Injection on Bone Mineral Density and Bone Turnover Markers.
Epidural steroid injection (ESI) is widely used to manage low back pain. ESIs are commonly performed to treat pain accompanying intervertebral disc prolapse, spinal stenosis, facet joint pathologies, and other degenerative spinal pathologies. Corticosteroids for musculoskeletal conditions, regardless of the route of administration, can reduce bone mineral density (BMD) and increase the risk of fracture. With paraspinal administration of steroids, the severity of risk is enhanced as the steroid is being deposited in close proximity to bone. BMD and molecular markers of bone metabolism are the standard methods to assess the effect of any insult on bone strength and bone metabolism. Carboxy terminal crosslinked telopeptides of type 1 collagen (sCTX) and serum Procollagen Type I N-terminal propeptide (P1NP) are the reference markers of bone resorption and formation, respectively. ⋯ The study's primary limitations included its high dropout rate, a larger reference range for BTMs, making them a less specific tool for comparison, and the absence of a control group. ESI has a negative impact on the BMD of the hip and spine. Reduced BMD should be considered as a potential side effect of ESI.
