The role of low-level laser therapy (LLLT) in the management of carpal tunnel syndrome (CTS) is controversial. While some trials have shown distinct advantages of LLLT over placebo and some other non-surgical treatments, other trials have not. ⋯ The evidence is of very low quality and we found no data to support any clinical effect of LLLT in treating CTS. Only VAS pain and finger-pinch strength met previously published MCIDs but these are likely to be overestimates of effect given the small studies and significant risk of bias. There is low or very low-quality evidence to suggest that LLLT is less effective than ultrasound in the management of CTS based on short-term, clinically significant improvements in pain and finger-pinch strength. There is insufficient evidence to support LLLT being better or worse than any other type of non-surgical treatment in the management of CTS. Any further research of LLLT should be definitive, blinded, and of high quality.

In a recent cluster analysis, it has been shown that patients with peripheral neuropathic pain can be grouped into 3 sensory phenotypes based on quantitative sensory testing profiles, which are mainly characterized by either sensory loss, intact sensory function and mild thermal hyperalgesia and/or allodynia, or loss of thermal detection and mild mechanical hyperalgesia and/or allodynia. Here, we present an algorithm for allocation of individual patients to these subgroups. The algorithm is nondeterministic-ie, a patient can be sorted to more than one phenotype-and can separate patients with neuropathic pain from healthy subjects (sensitivity: 78%, specificity: 94%). ⋯ In peripheral nerve injury, frequencies were 37%, 59%, and 50%, and in postherpetic neuralgia, frequencies were 31%, 63%, and 46%. For parallel study design, either the estimated effect size of the treatment needs to be high (>0.7) or only phenotypes that are frequent in the clinical entity under study can realistically be performed. For crossover design, populations under 200 patients screened are sufficient for all phenotypes and clinical entities with a minimum estimated treatment effect size of 0.5.

All nurses care for patients with pain, and pain management knowledge and attitude surveys for nurses have been around since 1987. However, no validated knowledge test exists to measure postlicensure clinicians' knowledge of the core competencies of pain management in current complex patient populations. To develop and test the psychometric properties of an instrument designed to measure pain management knowledge of postlicensure nurses. ⋯ A high decision consistency reliability was identified, with test cut-score of 75%. The final 23-item Clinical Pain Knowledge Test has acceptable discrimination, difficulty, decision consistency, reliability, and validity in the general clinical inpatient nurse population. This instrument will be useful in assessing pain management knowledge of clinical nurses to determine gaps in education, evaluate knowledge after pain management education, and measure research outcomes.

Randomized Controlled Trial Comparative Study
Pupillometry-guided Intraoperative Remifentanil Administration versus Standard Practice Influences Opioid Use: A Randomized Study.
Pupillometry has shown promising results for assessing nociception in anesthetized patients. However, its benefits in clinical practice are not demonstrated. The aim of this prospective randomized study was to evaluate the impact of intraoperative pupillometry monitoring on perioperative opioid consumption in major gynecologic surgery. ⋯ The use of pupillometry to guide intraoperative analgesia reduced intraoperative remifentanil consumption and postoperative morphine requirements. The possible consequences of decreasing intraoperative remifentanil in terms of chronic pain require further investigation.

The interpersonal theory of suicide offers a conceptual framework for understanding suicidal ideation (SI) that may be applicable to individuals with chronic pain. The theory emphasizes the importance of 2 interpersonal constructs as precursors to SI: perceived burdensomeness (the belief that one has become a burden to others) and thwarted belongingness (a lack of social integration or connection). Our objective was to test the interpersonal theory of suicide in people with chronic pain. ⋯ These findings are in line with some, but not all, of the major predictions of the interpersonal theory of suicide. In general, however, they support the relevance of the theory for individuals with chronic pain.
