The scarcity of an effective and safe therapy to relieve acute zoster-related trigeminal neuralgia (TN) and preventing it from developing into trigeminal postherpetic neuralgia is well known. Pulsed radiofrequency (PRF) is a novel and safe, minimally neuro-destructive technique for the treatment of acute zoster-related TN, which attains satisfactory pain relief. However, this result is only reported by a few single-center researches. In addition, no study has reported the predictive factors of the analgesic effect for PRF treatment on acute zoster-related TN patients. ⋯ CT-guided PRF is an effective and safe treatment for acute zoster-related TN patients. Compared to peripheral nerve PRF, gasserian ganglion treatment may be more effective for patients with acute zoster-related TN.

Randomized Controlled Trial
Ultrasound-Guided Oblique Sagittal Anterior Quadratus Lumborum Block in Total Hip Arthroplasty: A Randomized Controlled Trial.
The anterior quadratus lumborum block (QLB) is gaining popularity in total hip arthroplasty (THA) surgeries for postoperative pain management and this technique rarely results in lower limb muscle weakness. However, no studies have described the range of its blockade. ⋯ Ultrasound-guided oblique sagittal anterior QLB can reduce the analgesics required after and during THA and the postoperative VAS pain scores, but it rarely affects muscle strength.

Prescription opioid misuse is an ongoing epidemic in the United States. Though the number of people misusing prescription opioids is declining, the prevalence of abuse and dependence remains stable. This highlights the need to identify and intervene in factors leading to the escalation of prescription opioid misuse. ⋯ Study results suggest the importance of the frequency of prescription opioid misuse as a possible risk factor for dependence and emphasize the need to monitor for misuse even in instances of acute pain.

Ultrasound-guided (ULSD-g) genicular nerve blocks (GNB) using pharmacological agents for pain control in chronic knee osteoarthritis (OA) are gaining in popularity. There lacks a systematic review to evaluate the ULSD techniques and pharmacological agents used during the intervention, and to assess the knee's function postintervention. ⋯ There is fair evidence to at least target the superior medial genicular nerve, inferior medial genicular nerve, and Inferior medial genicular nerve using local anesthetics, corticosteroids, or alcohol to reduce pain and to improve knee function in patients with chronic knee OA under ULSD guidance. The procedure is safe but more research is needed to determine the optimal interventional approach.
