Background: Arthroscopic rotator cuff repair (ARCR) often causes unbearable postoperative pain, even more severe than before surgery. Opioids are the drugs of choice for temporary postoperative analgesia. However, this conventional approach also has some side effects and potential for drug abuse. The aims of this study are expected to verify the effect of 5% lidocaine patch (LP5) on the intensity of early postoperative pain, functional recovery and quality of life in patients undergoing ARCR.
Methods: In this randomized, double-blind, and placebo-controlled clinical trial, a total of 102 postoperative patients undergoing ARCR will be randomly assigned to either the LP5 group, receiving topical lidocaine analgesia, or the placebo control group. The primary outcome measure will be the change in the American Shoulder Elbow Surgeons score from pre-operation to 90 days post-operation. Secondary outcomes will include pain scores, range of motion, opioid use, safety indicators, blinding assessment and several shoulder function score questionnaires. The effect of the allocated treatment will be assessed at preoperative baseline and at 7-, 14-, 30- and 90-day postoperatively.
Discussion: In this study, the efficacy and safety of the 5% lidocaine patch will be evaluated in terms of short-term clinical symptoms in patients undergoing ARCR. The results of this study will help determine whether LP5 is effective in early functional recovery in ARCR and whether it relieves pain and reduces opioid consumption.

Objective: The current landscape is characterized by a dearth of effective, safe, simple, and noninvasive methods for preventing pain following craniotomy. This clinical trial seeks to evaluate the efficacy profile of preemptive application of a topical 5% lidocaine patch in alleviating post-craniotomy pain.
Methods: This was a multi-centric, prospective randomized placebo-controlled triple-blind clinical trial.
Highly Water-Soluble Microneedle Patch for Short Wear Time and Rapid Drug Delivery.

Article Synopsis
- * The development of a new type of microneedle (MN) patch, made from a polymer/drug mix, allows for quick and painless application to the skin for both local and systemic drug delivery.
- * A specific MN patch design using polyvinylpyrrolidone (PVP) and lidocaine (L) with added sodium bicarbonate (NaB) enhances MN dissolution speed by 60%, enabling a much shorter wear time for effective pain relief.

Article Synopsis
- - The study reviewed the effectiveness of topical medications for diabetic neuropathic pain (DNP) and compared them with oral pain relief options.
- - The most promising topical treatments identified were 8% Capsaicin patches and 5% Lidocaine patches, along with evidence supporting topical clonidine, gabapentin, and amitriptyline.
- - Topical medications could be viable alternatives to oral medications for DNP, and further research is needed on combining different topical treatments for better effectiveness.

Background: With an aging population, knee arthroplasty is increasingly common; however, chronic postsurgical pain (CPSP) affects up to 30% of patients. This study aims to evaluate the efficacy of 5% lidocaine-medicated plaster (LP5) in preventing CPSP among patients undergoing knee arthroplasty.
Methods: This is a dual-center, randomized, double-blind, placebo-controlled trial involving 128 adult patients scheduled for knee arthroplasty.
