The objective of this prospective, randomized study was to evaluate the effect of pre-emptive local infiltration of lidocaine, lidocaine plus dexamethasone, levobupivacaine and levobupivacaine plus dexamethasone on postoperative pain in Modified Radiofrequency Assisted Uvulopalatoplasty (MRAUP) cases. Sixty adult patients (44 males and 16 females) aged 32-51 years with simple snoring were divided into four groups. The anesthesia of the patients in the first group was achieved with lidocaine HCl, in the second group, with lidocaine HCl and dexamethasone sodium phosphate, in the third group, with levobupivacaine, and in the fourth group, levobupivacaine and dexamethasone sodium phosphate. All the patients were applied Modified Radiofrequency Assisted Uvulopalatoplasty technique. The pain experienced by the patients during swallowing and at rest on the 1st, 3rd, 5th, 7th, and 10th day and analgesic consumption were evaluated using standard 10 cm visual analog scales. The mean duration of operation in the group that received lidocaine HCl was 22 ± 3 min, while in the group that received levobupivacaine HCl was 27 ± 4 min. There were statistically significant differences between the groups for analgesic effects on the 1st, 3rd, 5th, and 7th day and for the amount of analgesics used, on the 1st, 3rd, and 5th day. The best results were obtained in the group that received levobupivacaine HCl and steroid (p < 0.001). Steroid and local anesthetic combinations are superior to controls in the management of postoperative pain in MRAUP surgery.

January 2025
Research Department, Valley Vein Health Center, Turlock, CA, USA.
Purpose: Determine the rate of incidence, risk factors, and management for developing venous thromboembolism (VTE) in patients undergoing radiofrequency ablation (RFA) and ultrasound-guided foam sclerotherapy (UGFS) for varicose veins.
Methods: All charts of patients undergoing venous ablation from 2016 to 2023 were reviewed at a rural vein treatment clinic. The incidence of VTE was noted and a chart review was completed to identify risk factors for VTE, EHIT score, EFIT score, and management.
Impact of Synchronized Radiofrequency and High-Intensity Facial Electrical Stimulation on Facial Muscles and the Superficial Fascial System in the Midface.

Department of Dermatology, Erasmus Universiteit Rotterdam, Rotterdam, Netherlands.
Background: Midfacial aging involves skeletal changes, muscle weakening, and fat redistribution, resulting in volume loss, skin sagging, and deepened nasolabial folds. High-Intensity Facial Electrical Stimulation (HIFES) combined with Radiofrequency (RF) is a novel non-invasive method to address these changes by enhancing muscle mass and remodeling subcutaneous tissue.
Objectives: To assess the efficacy of HIFES and Synchronized RF in improving midfacial aesthetics, specifically muscle thickness, skin displacement, and facial volume.
Radiofrequency Coblation Inferior Turbinoplasty with Modified UPPP for the Treatment of Obstructive Sleep Apnea-Hypopnea Syndrome.

Department of Otolaryngology, Qingdao Municipal Hospital, Qingdao, Shandong, China.
To compare the efficacy of surgical treatment in patients with obstructive sleep apnea-hypopnea syndrome (OSAHS) involving a standalone modified uvulopalatopharyngoplasty (mUPPP) and radiofrequency coblation inferior turbinoplasty with mUPPP. In this study, a retrospective analysis of 79 OSAHS patients with inferior turbinate hypertrophy and oropharyngeal obstruction undergoing surgical treatment was performed. According to the different surgical methods, the patients were divided into 2 groups (Group A and Group B).

Double-quantum filtered Na NMR experiments with one or two "magic angle" (54.7°) pulses in the filter step are widely used for selective observation of sodium ions that are interacting with ordered biological structures ("ordered sodium") and hence exhibit a distribution of quadrupolar splittings in their NMR spectrum. This approach has recently been extended to Na MRI where the conventional experiment has been modified, omitting the 180° pulse to reduce the absorption of radiofrequency energy during human studies.

Polymeric coronary stents, like the ABSORB™, are commonly used to treat atherosclerosis due to their bioresorbable and cell-compatible polymer structure. However, they face challenges such as high strut thickness, high elastic recoil, and lack of radiopacity. This study aims to address these limitations by modifying degradable stents produced by additive manufacturing with poly(lactic acid) (PLA) and poly(ε-caprolactone) (PCL) with degradable metallic coatings, specifically zinc (Zn) and magnesium (Mg), deposited via radiofrequency (rf) magnetron sputtering.
