Objectives: We aimed to compare the treatment response with simultaneous application of transforaminal epidural steroid injection (TESI) and pulsed radiofrequency (PRF) to the lumbar dorsal root ganglion (DRG) with TESI in patients with chronic lumbar radicular pain.
Methods: A total of 129 patients were enrolled. TESI was performed to 67 patients and TESI+DRG-PRF was performed to 62 patients. Demographic data, surgical records, and medications, side, and level of the procedure were recorded. Patients were evaluated on the pre-operative and post-operative 10th day, 1st and 3rd month follow-up visits, and visual analog scale (VAS, 0-10) scores, and patients' satisfaction assessment on the 3rd month follow-up were collected. A successful therapeutic response was defined as a 50% or more reduction in VAS scores.
Results: In both groups, post-operative VAS scores were significantly lower than the pre-operative levels (p<0.001). VAS scores in the TESI+DRG-PRF group were significantly lower than the TESI group at all follow-up periods (p˂0.001). Reduction ratios in VAS scores were significantly higher in the TESI+DRG-PRF group in all follow-up visits (p˂-0.001). Satisfaction levels were significantly higher in the TESI+DRG-PRF group (p˂0.01).
Conclusion: According to our study, TESI provides short-moderate pain relief in patients with chronic lumbar radicular pain. A simultaneous application of PRF in the same session with TESI should be considered as an option to improve the treatment response.

Our study aimed to investigate the clinical benefits of combining pulsed radiofrequency (PRF) and platelet-rich plasma (PRP) techniques for treating chronic lumbosacral radicular (CLSR) pain resulting from grade I spondylolisthesis (G1SL). Ninety-six patients with CLSR pain between March 2021 and March 2023 were included in this study, 58 patients with G1SL without instability on dynamic radiographs - Group A and 38 patients with instability - Group B. Pre-procedure, Group B had higher pain levels than Group A.

The efficacy of radiofrequency ablation (RFA) in patients with atrial fibrillation (AF) and heart failure with preserved ejection fraction (HFpEF) has been established, but the efficacy and safety of cryoballoon ablation (CBA) and pulsed field ablation (PFA) remain unclear. This retrospective cohort study included 223 patients with paroxysmal non-valvular AF and HFpEF who underwent their first AF ablation between January 2017 and December 2021 and were divided into RFA (n = 77), CBA (n = 127), and PFA (n = 19) groups. After a mean follow-up of 11.

Catheter ablation is a widely used treatment modality for various cardiac tachyarrhythmias, including atrial and ventricular arrhythmias. Although it is generally considered safe, the procedure carries potential complications, with coronary artery injury being one of the most significant. The aim of this systematic review was to assess the incidence, mechanisms, contributing factors, diagnostic strategies, and preventive measures related to coronary artery injury in patients undergoing catheter ablation, including radiofrequency catheter ablation, cryoablation, and pulsed-field ablation.

Department of Optical Science and Engineering, Shanghai Ultra-Precision Optical Manufacturing Engineering Center, Fudan University, Shanghai 200433, China.
In recent years, the fabrication of materials with large nonlinear optical coefficients and the investigation of methods to enhance nonlinear optical performance have been in the spotlight. Herein, the bismuth telluride (BiTe) thin films were prepared by radio-frequency magnetron sputtering and annealed in vacuum at various temperatures. The structural and optical properties were characterized and analyzed using X-ray diffraction, scanning electron microscopy, X-ray photoelectron spectroscopy, spectroscopic ellipsometry, and UV/VIS/NIR spectrophotometry.

Recurrent lumbar disc herniation (RLDH) refers to a lumbar disc herniation (LDH) that recurs at the same level, location, and side following surgical repair. This study aimed to evaluate the efficacy of transforaminal epidural steroid injection (TESI) and dorsal root ganglion pulsed radiofrequency (DRG PRF) therapy with and without caudal epidural steroid injection (CESI) for the treatment of lumbar radicular pain (LRP) associated with RLDH. This retrospective cohort study included 57 patients treated for RLDH in a hospital pain clinic between September 2022 and February 2024.
