Reproducibility: reliability and agreement parameters of the Revised Short McGill Pain Questionnaire Version-2 for use in patients with musculoskeletal shoulder pain.
The Revised Short McGill Pain Questionnaire Version-2 (SF-MPQ-2) is a multidimensional outcome measure designed to capture, evaluate and discriminate pain from neuropathic and non-neuropathic sources. A recent systematic review found insufficient psychometric data with respect to musculoskeletal (MSK) health conditions. This study aimed to describe the reproducibility (test-retest reliability and agreement) and internal consistency of the SF-MPQ-2 for use among patients with musculoskeletal shoulder pain. ⋯ Good reproducibility supports the SF-MPQ-2 domains for augmented or independent use in MSK-related shoulder pain assessment, with the total scale displaying the best reproducibility coefficients. Additional research on the validity and responsiveness of the SF-MPQ-2 is still required in this population.

Randomized Controlled TrialAnalgesic efficacy of infiltration between the popliteal artery and capsule of the knee (iPACK) block added to local infiltration analgesia and continuous adductor canal block after total knee arthroplasty: a randomized clinical trial.
A combination of motor-sparing analgesia with local infiltration analgesia (LIA) and continuous adductor canal block (CACB) may improve postoperative pain and functional recovery for total knee arthroplasty (TKA). We hypothesized that the addition of a novel technique for posterior knee block, known as the infiltration between the popliteal artery and capsule of the knee (iPACK) block, to LIA with CACB would reduce opioid requirements. ⋯ The addition of an iPACK block to the LIA and CACB does not reduce the postoperative opioid consumption nor improve analgesia. However, it may improve immediate functional performance and reduce the length of hospitalization after TKA.

Neuropathic facial pain occurs due to pathologic dysfunctions of a nerve responsible for mediating sensory fibers to the head. Surgical interventions, in cases of failed medical therapy, include microvascular decompression, radiofrequency (RF) ablation, percutaneous balloon decompression, and stereotactic radiosurgery. In this review, we focused on RF ablation as a treatment for chronic facial pain. ⋯ This systematic review found evidence that RF ablation is efficient in treating patients with facial pain, as well as in improving quality of life and reducing oral medication use. Maximal pain control is achieved using combined CRF and PRF therapy. Complications are uncommon and include facial numbness, masseter weakness, cheek hematomas, diminished corneal reflex, and dry eyes.

A Secondary Analysis from a Randomized Trial on the Effect of Plasma Tetrahydrocannabinol Levels on Pain Reduction in Painful Diabetic Peripheral Neuropathy.
This report examines the association between tetrahydrocannabinol (THC) plasma levels and pain response in a secondary analysis of data from a recent diabetic neuropathy study that demonstrated a dose-dependent reduction in spontaneous and elicited pain at specific time points. A randomized, double-blinded, placebo-controlled crossover study was conducted in sixteen patients with painful diabetic peripheral neuropathy. Subjects participated in four sessions, separated by 2 weeks, during each of which they were exposed to one of four conditions: placebo, or 1%, 4%, or 7% THC dose of cannabis. ⋯ Perspective: This analysis correlating plasma THC levels and pain reduction in diabetic neuropathy suggest a therapeutic window. Low and high THC levels had a negative association (no reduction) and THC levels within the window had a positive association (reduction). There was a minor negative linear effect of THC on cognitive function.
