Randomized Controlled TrialEffect of individualized anesthesia and analgesia on postoperative pain in patients stratified for pain sensitivity: A study protocol for the PeriOPerative individualization trial randomized controlled trial.
Despite advancements in surgical and anesthesia techniques, acute and persistent postoperative pain are still a common challenge. Postoperative pain has direct effects on individual patient care and outcome, as well as putting strain on limited health care resources. Several prediction methods for postoperative pain have been described. One such method is the assessment of pain during peripheral venous cannulation (VCP). It is not known if different approaches to anesthesia and analgesia, depending on the evaluation of risk for postoperative pain, can improve outcome. The aim of this study is to evaluate if individualized anesthesia and analgesia can affect postoperative pain and recovery after surgery, in patients stratified by VCP. ⋯ Individualized perioperative pain management has the potential to improve patient care. This study will examine the impact of different anesthesia and analgesia regimes, in patients with differing pain sensitivity, on postoperative pain.

Randomized Controlled Trial
Clinical benefit of botulinum toxin for treatment of persistent TMD-related myofascial pain: A randomized, placebo-controlled, cross-over trial.
Injections of botulinum toxin type A (BoNT-A) have been proposed as an additional treatment modality for patients suffering chronic temporomandibular disorder (TMD)-related myofascial pain (MFP). BoNT-A impairs muscle function, along with its analgesic effect, and a minimal effective dose should be used. The objective of this randomized placebo-controlled crossover study was to evaluate the clinical benefit of a moderate dose (50 U) of BoNT-A. ⋯ Injections of 50 U of BoNT-A might improve MFP symptoms, but the specific effect of the drug on pain compared to the placebo is not obvious.

Commonly used models for eliciting muscle pain involve the injection of algesic substances or the induction of delayed onset muscle soreness. The former require invasive procedures, and the time frame for pain induction and subsidence in the latter can be inconvenient. This study presents a detailed spatiotemporal characterization of a new experimental model of muscle pain based on short-wave diathermy (SWD), developed to overcome the limitations of existing models. ⋯ SWD produces deep heating in muscles by converting electromagnetic energy to thermal energy. It was previously shown that it can be used to elicit experimental pain in the forearm muscles, and the present study demonstrates that this can be reliably generalized to other body sites, such as the shoulder. Furthermore, SWD application is non-invasive and presents a convenient time frame for pain induction and subsidence, thus overcoming limitations associated with traditional muscle pain models.

Noncancer chronic pain is a clinical challenge because pharmacological treatment often fails to relieve pain. Transcranial direct current stimulation (tDCS) is a treatment that could have the potential for pain relief and improvement in quality of life. However, there is a lack of clinical trials evaluating the effects of tDCS on the pain system. The aim of the present study was to evaluate the effect of 5 days of anodal tDCS treatment on the pain system in patients with chronic noncancer pain using quantitative sensory testing and quality of life questionnaires: (1) Brief Pain Inventory-short form, (2) European Organization for Research and Treatment of Life Questionnaire-C30, and (3) Hospital Anxiety Depression Scale. ⋯ This study adds to the evidence in the literature that tDCS may be a potential therapeutic tool for the management of noncancer chronic pain.

Randomized Controlled Trial Multicenter Study
Efficacy of naproxen in patients with sciatica: multicentre, randomized, double-blind, placebo-controlled trial.
This trial assessed the efficacy of naproxen in patients with sciatica in outpatient clinics across 4 Norwegian hospitals. A total of 123 adults with radiating pain below the knee (≥4 on a 0-10 numeric rating scale) and signs consistent with nerve root involvement were included. Participants were randomized to receive either naproxen 500 mg or a placebo twice daily for 10 days. ⋯ No differences were found for sciatica bothersomeness or consumption of rescue medication or opioids. Participants in the naproxen group exhibited an adjusted odds ratio of 4.7 (95% CI 1.3-16.2) for improvement by 1 level on the global perceived change scale. In conclusion, naproxen treatment showed small, likely clinically unimportant benefits compared with placebo in patients with moderate-to-severe sciatica.
