Examine how interventional pain physicians navigated the early phase of reopening practices during the coronavirus disease 2019 (COVID-19) pandemic. ⋯ COVID-19 has dramatically affected interventional pain practices with regard to telehealth, in-clinic precautions, screening/testing protocols, and patient counseling. Practice patterns will continue to evolve as we learn more about the disease and improve methods to provide safe and effective care.

The treatment for neuropathic pain is still a big challenge. Pulsed radiofrequency technique has been widely used to relieve neuropathic pain in recent years. The purpose of this study is to optimize the temperature for pulsed radiofrequency therapy. ⋯ PRF using 50°C could induce less damage while achieving better improvement of mechanical and thermal pain threshold than 42°C and 60°C in CCI rats, which may be achieved by promoting the expression of M-ENK in spinal cord.

Radiofrequency Ablation for Chronic Posterior Sacroiliac Joint Complex Pain: A Comprehensive Review.
Radiofrequency ablation of the sacral lateral branches targets the innervation of the posterior sacroiliac ligaments and posterior portion of the sacroiliac joint. These structures are also collectively referred to as the posterior sacroiliac joint complex. This review will discuss current diagnostic block paradigms and selection criteria for sacral lateral branch radiofrequency ablation, varying techniques and technologies utilized for sacral lateral branch radiofrequency ablation, and updates on the clinical outcome literature. The current evidence suggests that sacral lateral branch radiofrequency ablation can provide relief for posterior sacroiliac joint complex pain, but the literature is limited by variability in selection criteria, the specific nerves targeted by radiofrequency ablation, and the types of radiofrequency ablation technology and techniques utilized in clinical outcome studies.
