Observational Study
Comparative Descriptive Analysis of Physician Versus Patient-Directed Gabapentin Usage In Chronic Pain - A Preliminary Report.
Gabapentin is one of the most common medications employed in Pain Medicine, specifically targeting the management of neuropathic pain. We are most familiar with the incremental dosing strategy where a ceiling dose is eventually attained guided by efficacy and patient tolerance, after which a fixed dosing regimen is prescribed. We propose that autonomous short-term dose variations per patient could have rapid clinically significant effects in the management of chronic pain. ⋯ This pilot study suggests that a significant portion of patients choose to administer variable doses of gabapentin and associate this with better efficacy and satisfaction. A larger study is needed to confirm this supposition. Based upon this pilot study, the variable dosing option may be an option for improved therapeutic efficacy or as an alternative to those whose lifestyles do not allow for fixed dosing regimens. Discussion of the risks of gabapentin, including respiratory depression, and clear dosage parameters of use, would need to be outlined when considering a variable dose regimen.

Radiofrequency thermocoagulation of genicular nerves is an effective treatment for chronic pain due to knee osteoarthritis. The procedure can be performed under fluoroscopic or ultrasonographic guidance. ⋯ The final position of the needle tip in radiofrequency thermocoagulation of genicular nerves can exist at the one-third anterior of the bone shaft, without a need for further advancing the needle to the posterior portion. Although performed more distally compared to fluoroscopy guidance, ultrasound-guided genicular nerve radiofrequency thermocoagulation still provides effective analgesia.

Randomized Controlled Trial
Effect of Radiofrequency on Dorsal Root Ganglion Versus Transforaminal Steroids Injection on Tumor Necrosis Factor-Alpha Level in Lumbar Radicular Pain.
The mechanism of pain control with pulsed radiofrequency (PRF) is unclear. ⋯ Combined PRF on DRG with TFESI showed similar outcomes to TFESI-alone in relieving pain in patients with lumbar disc prolapse. However, PRF on DRG caused a significant decrease in TNF-a serum levels at 3 months.

Randomized Controlled Trial
Analgesic Effect of Addition of Pectointercostal Block to Serratus Anterior Plane Block in Breast Surgeries: A Randomized, Controlled Trial.
Ultrasound-guided serratus anterior plane block (SAPB) is an efficient perioperative analgesic modality for breast surgeries. SAPB does not block the anterior cutaneous branches of the intercostal nerves; thus, it does not provide adequate analgesia for the parasternal region and the medial side of the breast. A new parasternal block, the pectointercostal fascial plane block (PIFB) has been developed to overcome this issue. ⋯ The number of patients who needed intraoperative fentanyl, as well as the MABP and heart rate were significantly lower in Group 2 (SAPB+PIFB). Postoperative vital signs, VAS, postoperative analgesic requirements, and opioid consumption were comparable for both groups. Patient satisfaction was comparable for both groups, while surgeon satisfaction was higher in Group 2 (SAPB+PIFB) but statistically not significant.

Percutaneous radiofrequency thermocoagulation (RFT) through the foramen rotundum (FR) is a new approach for the treatment of V2 trigeminal neuralgia (TN). Some studies have shown the novel method seems to have advantages over traditional RFT through the foramen ovale (FO). The optimal interventional surgical strategy for isolated V2 TN remains controversial. ⋯ In conclusion, RFT of the maxillary nerve through the FR for the treatment of primary V2 TN had a better long-term effect rate and fewer complications in comparison with thermocoagulation of the Gasserian ganglion through the FO. No differences were found between both interventions in terms of immediate effect rate and recurrence rate.
