Treating Anxiety-Based Cognitive Distortions Pertaining to Somatic Perception for Better Chronic Pain Outcomes: A Recommendation for Better Practice in the Present Day and the Cyber Age of Medicine.

Anxiety-based cognitive distortions pertaining to somatic perception (ABCD-SPs)-primarily catastrophizing, fear avoidance, and kinesiophobia-have been repeatedly linked to worsening chronic, non-cancer pain (CNCP) outcomes of increased disability, amplified pain, ineffective opioid use, and opioid misuse. Several studies have suggested that treating ABCD-SPs can improve pain outcomes, yet identification and targeting of ABCD-SPs are not part of the standard medical pain assessment and treatment plan. Utilizing a narrative review of proposed mechanisms, published patient perspectives, and study correlations connecting these cognitive distortions with CNCP outcomes, an approach for better practice in the delivery of standard medical CNCP care can be deduced and formulated into a Belief and Behavior Action Plan (BBAP) for medical clinicians treating CNCP to implement into initial and maintenance care planning. These recommendations require relatively few resources to implement and have the potential to disseminate more effective CNCP treatment on a large scale now and in the future with the new frontier of cognitive computing in medicine.

Impact of tongue base mucosectomy on quality-of-life outcomes: systematic review and single-centre experience.

Tongue base mucosectomy (TBM) is a well-established procedure in investigating cervical squamous cell carcinoma of occult primary. However, its risks have not been balanced against its benefits with validated tools. A systematic literature review was conducted for reported complications and quality-of-life outcomes following TBM. The complications and quality-of-life outcomes following TBM at our institution are then reported using objective metrics and validated assessment tools, including Performance Status Scale for Head and Neck Cancer Patients (PSS-HNS), University of Washington Quality-of-life Questionnaire (UW-QOL) and M. D. Anderson Dysphagia Inventory (MDADI). Eighteen studies met the criteria for inclusion in the systematic review. Of these, 9 addressed swallowing outcomes described in text, without using validated assessment tools. No studies reported taste, speech and pain outcomes after TBM. Post-operative bleeding was not consistently reported. 20 patients underwent robotic TBM at our institution between 2017 and 2023. The primary tumour was identified in 50% (10/20) of cases. The median time to commencing soft diet and median time of NG feeding was 0 days. The median return to normalcy of diet score was 95. Median post-treatment UW-QOL pain and swallowing scores were 100 and 70 respectively. The median speech score was 100, saliva 70, and taste 70. The median normalised MDADI scores were: global 80; emotional 67; functional 80 and physical 65. Validated assessment tools better inform patients about treatment options and can help compare post-TBM results across institutions. Our data demonstrates that TBM patients have a functional post-operative swallow, are pain and gastrostomy free, even after adjuvant treatment. Routine post-operative insertion of NG tube is not necessary.

Pain Resilience and Coping Behaviors in Individuals in a Collectivist Social Context.

Pain resilience (PR) may be associated with different coping skills, resulting in differences in pain outcomes. This study aimed to understand the role of PR in dictating the choice of coping methods. This study completed a preliminary validation of the Mandarin Chinese version of the Pain Resilience Scale (PRS-C) with online survey data (n = 46). Further, we conducted interviews with individuals with chronic low back pain (n = 24). The PRS-C psychometric properties were assessed using a confirmatory factor analysis. The interviews explored pain history, treatment experiences, and coping strategies and were analyzed thematically. The validated PRS-C (10 items) demonstrated satisfactory psychometric properties. The interview results showed that participants who scored lower were more likely to adopt disengagement rather than engagement coping strategies. Qualitative data revealed three themes explaining why and how participants in this collectivist social framework chose their coping methods. The findings suggest that while participants tried to understand their pain and treatment experiences, the cognitive appraisal construct in PR influenced some of the coping experiences. However, deeply influenced by Confucianism and Buddhism, participants also expressed factors beyond the scope of individual fortitudes, such as the relationship with a higher power that significantly influenced their coping behaviors.

Content Evaluation of Pruritus, Skin Pain, and Sleep Disturbance Patient-Reported Outcome Measures in Adolescents and Adults With Moderate-to-Severe Atopic Dermatitis: Qualitative Interviews.

Pruritus, skin pain, and sleep disturbance are a significant burden to individuals with moderate-to-severe atopic dermatitis (AD) and negatively impact quality of life. Fit-for-purpose patient-reported outcome measures (PROMs) that assess AD-related pruritus, skin pain, and sleep disturbance are important for evaluating the effectiveness of new AD treatments. To evaluate content validity of five AD-related PROMs in adolescents and adults with moderate-to-severe AD (the Worst Pruritus Numeric Rating Scale [NRS], the AD Skin Pain NRS; the Sleep Disturbance NRS, the skin pain-specific Patient Global Impression of Change [PGIC], and the skin pain-specific Patient Global Impression of Severity [PGIS]) and to assess patient-reported experience with pruritus, skin pain, and sleep disturbance. A qualitative study in adolescents (aged 12-17 years) and adults with moderate-to-severe AD was conducted in two consecutive stages. In each stage, two iterative rounds of individual interviews were conducted by experienced interviewers. All interviews included concept elicitation and cognitive debriefing components. Data were analysed using thematic analysis. A total of 27 adults and 20 adolescents with moderate-to-severe AD participated in the initial content evaluation (Stage 1) of the Worst Pruritus NRS [1.0] and AD Skin Pain NRS [1.0] (n = 26; 16 adults, 10 adolescents) and in the subsequent content evaluation (Stage 2) of the revised Worst Pruritus NRS [1.1], revised AD Skin Pain NRS [1.1], Sleep Disturbance NRS, skin pain-specific PGIC, and skin pain-specific PGIS (n = 21; 11 adults, 10 adolescents). Results were generally aligned and consistent for both adult and adolescent participants. Additionally, we found that sleep disturbance is relevant and important for evaluation in adults and adolescents with moderate-to-severe AD (Stage 2), while also providing further confirmation of this for pruritus and skin pain (Stages 1 and 2). Our findings support the content validity of the revised Worst Pruritus NRS [1.1], revised AD Skin Pain NRS [1.1], Sleep Disturbance NRS, skin pain-specific PGIC, and skin pain-specific PGIS in individuals aged ≥12 years with moderate-to-severe AD. Furthermore, the findings support sleep disturbance, skin pain, and pruritus as being relevant and important features for both adolescents and adults with moderate-to-severe AD.

Perioperative intravenous lignocaine for pediatric postoperative pain-A systematic review and meta-analysis.

Intravenous lignocaine has been used as an analgesic adjunct in pediatric surgical patients, although its efficacy is still unclear. We aimed to clarify the efficacy of perioperative intravenous lignocaine (bolus followed by an infusion) on pediatric postoperative pain outcomes. A systematic review and meta-analysis. PubMed, EMBASE, Web of Science, Google Scholar (inception to June 2024). Studies involving pediatric patients (≤18 years) undergoing surgery under general anesthesia with one group receiving perioperative intravenous lignocaine (bolus followed by infusion) and the other group receiving placebo. The primary outcome was 24-h postoperative opioid consumption. Postoperative pain scores and the need for rescue analgesia were the secondary outcomes. Seven studies (n = 415) were included in the final meta-analysis. The use of intravenous lignocaine significantly reduced the morphine consumption in the first 24 h after surgery, compared to placebo (SMD -1.31, 95% CI -2.18 to -0.43, p = 0.003). A meta-analysis could not be performed for the secondary outcomes. There is low quality evidence to suggest that perioperative intravenous lignocaine bolus followed by an infusion significantly reduced the opioid consumption on the first postoperative day in pediatric surgical patients. The effects of perioperative lignocaine on postoperative pain scores and the need for rescue analgesia are uncertain.

Prognostic factors of pain, disability, and poor outcomes in persons with neck pain - an umbrella review.

The aim of this study was to identify prognostic factors pertaining to neck pain from systematic reviews. A search on PubMed, Scopus, and CINAHL was performed on June 27, 2024. Additional grey literature searches were performed. We conducted an umbrella review and included systematic reviews reporting the prognostic factors associated with non-specific or trauma-related neck pain and cervical radiculopathy. Prognostic factors were sorted according to the outcome predicted, the direction of the predicted outcome (worse, better, inconsistent), and the grade of evidence (Oxford Center of Evidence). The predicted outcomes were regrouped into five categories: pain, disability, work-related outcomes, quality of life, and poor outcomes (as "recovery"). Risk of bias analysis was performed with the ROBIS tool. We retrieved 884 citations from three databases, read 39 full texts, and included 16 studies that met all selection criteria. From these studies, we extracted 44 prognostic factors restricted to non-specific neck pain, 47 for trauma-related neck pain, and one for cervical radiculopathy. We observed that among the prognostic factors, most were associated with characteristics of the condition, cognitive-emotional factors, or socio-environmental and lifestyle factors. This study identified over 40 prognostic factors associated mainly with non-specific neck pain or trauma-related neck pain. We found that a majority were associated with worse outcomes and pertained to domains mainly involving cognitive-emotional factors, socio-environmental and lifestyle factors, and the characteristics of the condition to predict outcomes and potentially guide clinicians to tailor their interventions for people living with neck pain.

The use of abstract animations and a graphical body image for assessing pain outcomes among adults with sickle cell disease

Painimation, a novel digital pain assessment tool, allows patients to communicate their pain quality, intensity, and location using abstract animations and a paintable body image. This study determined the construct validity of pain animations and body image measures by testing correlations with validated pain outcomes in adults with sickle cell disease (SCD). Analyses used baseline data from a multisite randomized trial of 359 adults with SCD and chronic pain. Participants completed questionnaires on demographics, pain severity, frequency and interference, catastrophizing, opioid use, mood and quality of life, plus the Painimation app. Participants were categorized by selected pain animations, and were split into groups based on the proportion of painted body image. The “shooting” pain animation and greater body image scores associated with poorer pain outcomes in univariate analyses, except “happy” mood days. Potential confounding was evaluated by age, gender, race, education, disability, site, depression, and anxiety. Only depression scores significantly covaried in multivariate models, accounting for the effect of greater body image score and shooting animation on all outcomes except daily pain intensity. Both pain animations and body image measures correlated with validated pain outcomes, quality of life and mental health measures. This demonstrates animations and body image data can assess SCD pain severity, potentially with more accuracy than a 0-10 scale. In exploratory analyses, depression scores accounted for the association between Painimation and other pain outcomes. Future research will explore whether Painimation can differentiate biological and psychosocial pain components. PerspectiveThis article presents the preliminary construct validity of Painimation in sickle cell disease (SCD) by examining the associations of “pain animations” and body area image data with daily e-diary and traditional self-report pain outcomes.

Gender differences in postoperative pain, sleep quality, and recovery outcomes in patients undergoing visual thoracoscopic surgery

ObjectiveThe purpose of our study was to investigate the effect of gender on postoperative pain, sleep quality, and recovery outcomes in patients undergoing VATS surgery under general anesthesia. MethodPerioperative peripheral blood inflammatory markers system inflammation Index (SII) was recorded for perioperative inflammatory response. The visual analog scale (VAS) was used to evaluate pain level. And the Athens Insomnia Scale (AIS) was evaluated on the night before surgery (sleep preop 1), the first night after surgery (sleep POD 1), and the third night after surgery (sleep POD 3) for postoperative sleep. ResultIn this prospective cohort study, 79 males and 79 females were consecutively included. Females had significantly higher pain score (both rest and cough pain) compared to the males at 3 h after the surgery (3.85 ± 1.2 vs. 3.16 ± 1.1) (rest) (p < 0.001) and 5.10 ± 1.3 vs. 4.46 ± 1.6 (coughing) (p = 0.006)). Patients in the male group had significantly lower AIS scores than those in the female group at Sleep POD 1 and Sleep POD 3 (p = 0.024 and p = 0.045). And in both groups, postoperative SII was increased and statistically significant compared to preoperative SII (p < 0.001, respectively). Women presented higher levels of SII on the first day after surgery, and the increase of postoperative SII in females groups was significantly higher than that in male group when compared to preoperative SII (1806.33 ± 1314.8 vs 1430.55 ± 958.4) (p = 0.042). ConclusionThese findings highlight the complex multidimensional nature of postoperative pain, nausea and vomiting, sleep quality and the potential contributory role of sex in shaping these outcomes. Women had worse sleep quality, higher postoperative inflammatory response level and pain level than men.

What to expect following targeted muscle reinnervation/regenerative peripheral nerve interface: Pain outcomes in an amputee population

Targeted Muscle Reinnervation (TMR) and Regenerative Peripheral Nerve Interface (RPNI) have shown promise in improving and/or preventing neuropathic pain and reducing narcotic use in amputees. However, anecdotally, some patients experience an increase in pain in the first few months post-operatively. This study explored the pain trajectory of 22 upper and lower extremity amputees following their TMR and/or RPNI procedure in their first post-operative year, with a focus on the patterns of recovery the first few months. Our study found an overall decrease in the amount of pain and pain medication use at various time points post-operatively. Of note, several individuals had an increase in pain or required an increase in pain medications in the first three months. Different outcomes for patients who underwent primary versus secondary surgery were seen, which has been observed in other studies. Further prospective studies are warranted to evaluate these trends in pain after TMR or RPNI surgery in individuals with major limb amputations.

Ultrasound-guided infiltration with hyaluronic acid compared with corticosteroid for the treatment of Morton's neuroma.

A local injection may be used as an early option in the treatment of Morton's neuroma, and can be performed using various medications. The aim of this study was to compare the effects of injections of hyaluronic acid compared with corticosteroid in the treatment of this condition. A total of 91 patients were assessed for this trial, of whom 45 were subsequently included and randomized into two groups. One patient was lost to follow-up, leaving 22 patients (24 feet) in each group. The patients in the hyaluronic acid group were treated with three ultrasound-guided injections (one per week) of hyaluronic acid (Osteonil Plus). Those in the corticosteroid group were treated with three ultrasound-guided injections (also one per week) of triamcinolone (Triancil). The patients were evaluated before treatment and at one, three, six, and 12 months after treatment. The primary outcome measure was the visual analogue scale for pain (VAS). Secondary outcome measures included the American Orthopaedic Foot and Ankle Society (AOFAS) score, and complications. Both groups showed significant improvement in VAS and AOFAS scores (p < 0.05) after 12 months. The corticosteroid group had a significantly greater reduction in VAS and increase in AOFAS scores compared with the hyaluronic acid group, at one, three, and six months, but with no significant difference at 12 months. There were no complications in the hyaluronic acid group. There were minor local complications in six patients (six feet) (25.0%) in the corticosteroid group, all with discolouration of the skin at the site of the injection. These minor complications might have been due to the three weekly injections of a relatively high dose of corticosteroid. No patient subsequently underwent excision of the neuroma. An ultrasound-guided corticosteroid injection showed statistically significantly better functional and pain outcomes than an ultrasound-guided injection of hyaluronic acid for the treatment of a Morton's neuroma at many timepoints. Thus, a corticosteroid injection should be regarded as a primary option in the treatment of these patients, and the only indication for an injection of hyaluronic acid might be in patients in whom corticosteroid is contraindicated.

Music Therapy for Pain Management for People With Advanced Cancer: A Randomized Controlled Trial.

To improve mechanistic understanding, this randomized controlled trial examined anxiety, mood, emotional support, and pain-related self-efficacy as mediators of music therapy for pain management in people with advanced cancer. People with advanced cancer who had chronic pain were randomized (1:1) to 6 weekly individual music therapy or social attention control sessions. We measured mediators and pain outcomes (pain interference and pain intensity) using self-report measures at baseline, session 4, and post-intervention. We included outcome expectancy/treatment credibility, music reward, adult playfulness, and baseline pain interference and pain intensity as moderators. Participants (n=92) had a mean age of 56years. Most were female (71.7%), white (47.8%) or Black (39.1%), and had stage IV cancer (75%). Self-efficacy was found to be a significant mediator of music therapy for pain intensity (indirect effect ab=0.79, 95% CI 0.01-1.82) and pain interference (indirect effect ab=1.16, 95% CI 0.02-2.51), while anxiety, mood, and emotional support were not. The mediating effect of pain-related self-efficacy was significantly moderated by baseline pain interference but not by the other moderators. The findings suggest that the impact of music therapy on chronic pain is mediated by self-efficacy. This knowledge can help optimize music therapy interventions for chronic pain management for people with advanced cancer by capitalizing on teaching music-based self-management strategies.

Open Surgical Implantation of Lumbosacral Dorsal Root Ganglion Stimulators for Chronic Pain: Analysis of Patient Outcomes and Operative Technique

ObjectiveDorsal root ganglion (DRG) stimulator leads were designed to be placed percutaneously, yet open surgical placement via laminectomy is an option. We present the largest series to date of surgically-placed DRG stimulators and the first series where open surgical implantation was the chosen technique and not a salvage procedure. MethodsA retrospective review of a prospective database of DRG implants identified 17 patients who had open lumbosacral DRG lead placement performed by a single surgeon (NDT) between October 2021 and April 2023. Descriptive statistics, fluoroscopy exposure times, and complications were reported. The window of data collection was 1 month pre-operatively to 12 months post-operatively. Phone interviews were conducted to collect information on pain outcomes and patient satisfaction. ResultsWe identified 17 patients (12 women, 5 men) who had lumbosacral DRG placement. Phone interviews were conducted for 10/17 patients, with mean follow-up of 11.9 months. 53% reduction in mean pain score was achieved (n=10, p<0.001). There were no infections, hematomas, or symptomatic lead migrations. 1/17 experienced a superficial dehiscence and 2/17 had an intra-operative repairable durotomy with no post-operative sequelae. Mean fluoroscopy time per lead was 15.4±9.9s (n=10). ConclusionOpen DRG lead placement via laminotomy/laminectomy is reported as a salvage procedure but may have comparable safety and efficacy profile to percutaneous implantation when utilized as the primary implantation method. Before establishing open DRG as an alternative permanent implantation method, more studies are needed to determine whether such benefits as less migration outweigh the risks of a more invasive implantation procedure.

Outcome prediction following lumbar disc surgery: a longitudinal study of outcome trajectories, prognostic factors, and risk models.

This study aimed to 1) describe the 2-year postoperative trajectories of leg pain and overall clinical outcome after surgery for radiculopathy, 2) identify the preoperative prognostic factors that predict trajectories representing poor clinical outcomes, and 3) develop and internally validate multivariable prognostic models to assist with clinical decision-making. This retrospective cohort study included patients enrolled in the Canadian Spine Outcomes and Research Network who were diagnosed with lumbar disc pathology and radiculopathy and had undergone lumbar discectomy at one of 18 spine centers. Potential outcome predictors included preoperative demographic, health-related, and clinical prognostic factors. Clinical outcomes were 1) 2-year univariable latent trajectories of leg pain intensity (numeric pain rating scale) and 2) overall outcomes comprising multivariable trajectories showing the combined postoperative courses of leg and back pain intensity (numeric pain rating scale) together with pain-related disability (Oswestry Disability Index). Each outcome model identified a subgroup of patients classified as experiencing a poor outcome based on minimal change in their clinical status after surgery. Multivariable risk model performance and internal validity were evaluated with discrimination and calibration statistics based on bootstrap shrinkage with 500 resamplings. The authors included data from 1142 patients (47.6% female). The trajectory models identified 3 subgroups based on the patients' postoperative courses of pain or disability: 88.6% of patients in the leg pain model and 71.9% in the overall outcome model experienced a good-to-excellent outcome. The models classified 11.4% (leg pain outcome) and 28.2% (overall outcome) of patients as experiencing a poor clinical outcome, which was defined as minimal improvement in pain or disability after surgery. Eleven individual demographic, health, and clinical factors predicted patients' poor leg pain and overall outcomes. The performance of the multivariable risk model for leg pain was inadequate, while the overall outcome model had acceptable discrimination, calibration, and internal validity for predicting a poor surgical outcome. Patients with lumbar radiculopathy experience heterogeneous postoperative trajectories of pain and disability after lumbar discectomy. Individual preoperative factors are associated with postoperative outcomes and can be combined within a multivariable risk model to predict overall patient outcome. These results may inform clinical practice but require external validation before confident clinical implementation.

Effects of adding intravenous midazolam to a dual postoperative nausea and vomiting regimen in patients undergoing breast surgery: A pragmatic randomized controlled trial

Background: For high-risk patients, adding a third antiemetic drug to dual postoperative nausea and vomiting (PONV) prophylaxis is controversial. Given the established antiemetic properties of midazolam, this study compared the combination of low-dose dexamethasone-ondansetron and midazolam with high-dose dexamethasone-ondansetron. Methods: A total of 300 female patients scheduled for breast surgery were recruited and randomly assigned to two groups. The DO group received dexamethasone 8 mg and ondansetron 4 mg, whereas the DOM group received dexamethasone 4 mg, ondansetron 4 mg, and midazolam 0.04 mg/kg. The primary outcome was the incidence of PONV within 24 h. Secondary outcomes were PONV severity, antiemetic requirement, blood glucose levels, satisfaction and sedation scores, time to eye opening and extubation, pain outcome, and sore throat. Results: Primary outcome analysis included 298 patients. Incidence of PONV within the first 24 h after surgery occurred in 52 of 150 (35%) patients in the DO group and 33 of 148 (22%) patients in the DOM group (adjusted risk ratio, 0.63; 95% confidence interval, 0.45–0.88; P = 0.007). The antiemetic requirement was significantly greater in the DO group compared with the DOM group (P = 0.034). However, a significantly higher sedation level and longer time for eye-opening and extubation were observed in the DOM group (P &lt; 0.05). Conclusion: Compared to high-dose dexamethasone and ondansetron alone, midazolam combined with low-dose dexamethasone and ondansetron decreased the incidence of PONV in patients undergoing breast surgery; however, it increased the sedation level in the early postoperative period.

Preoperative Osteoporosis Is Associated with Increased Healthcare Utilization and Compromised Pain and Function Improvement after Primary Total Hip Arthroplasty: A Prospective Cohort Analysis

Osteoporosis (OP) has been linked to complications after total hip arthroplasty (THA), but its impact on healthcare utilization and patient-reported outcomes remains unclear. This study aimed to evaluate the association between: 1) pre-THA OP and healthcare utilization as well as patient-reported pain and function outcome measures; and 2) Dual Energy X-ray Absorptiometry (DEXA) scan-based T-scores and the aforementioned outcomes. A retrospective analysis of prospectively collected data of primary THA (2015 to 2018) was performed (n = 5,321) from a validated academic institutional database of a large North American tertiary health care system; of which 4,074 (76.6%) completed one-year follow-up. Outcomes included prolonged length of stay [LOS] > 3 days, discharge disposition, 90-day readmission, and one-year reoperation, as well as Hip Disability and Osteoarthritis Outcome Score (HOOS]) Pain, HOOS-function (PS), and minimal clinically important difference thresholds (MCID), and satisfaction. The prevalence of OP pre-THA was 56.9%, of which 39.8% were not prescribed OP medications and 15.3% had a DEXA scan. Compared to those who did not have OP, those who had OP were independently associated with higher odds of prolonged LOS, non-home discharge, 90-day readmission, and 1-year reoperation (P < 0.005). Furthermore, they had significantly higher odds of failing to achieve MCID (odds ratio (OR): 1.41 (95% confidence interval (CI): 1.06 to 1.89)) for HOOS-PS and satisfaction (OR: 1.5 (95% CI: 1.16 to 1.93)) at 1-year. Higher T-scores were associated with lower odds of prolonged LOS, non-home discharge, failure to achieve MCID in HOOS-Pain, and HOOS-PS. Over half of patients had OP, however, only 15.3% of patients had a DEXA scan prior to THA. Patients who had OP were at higher risk of prolonged LOS, non-home discharge, 90-day readmission, and one-year reoperation in addition to poor pain/function improvement and dissatisfaction one year after THA.

Scaphocapitate Arthrodesis for Wrist Deformities: A Systematic Review.

Scaphocapitate arthrodesis (SCA) is a described technique for chronic wrist pathology such as Kienbock disease and carpal instability. The technique aims to preserve motion, while maintaining carpal height, preserving the radioscaphoid articulation, and offloading the lunate. Limited case series evaluate the outcomes of this previously described technique. We aim to determine if the collective, updated literature on outcomes of SCA support its continued application by the wrist surgeon. Furthermore, we investigated if any technical variations offer an advantage in improving patient-reported outcomes after SCA. A literature search was performed using Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Articles selected for critical review were examined for patient demographic data, functional outcomes, radiographic outcomes, and complications. A qualitative analysis was then performed to synthesize the available date. A total of 18 unique articles published between 1991 and 2022 were identified, representing a total of 285 individual cases of SCA. Nonunion rate ranged 0%-22%. Preoperative visual analog scale pain scores ranged from 3.2 to 10, whereas postoperative visual analog scale pain scores ranged from 0 to 4. Patient-reported outcomes are reported by validated instruments, including the Disabilities of the Arm, Shoulder, and Hand, QuickDASH, Patient-rated Wrist Evaluation, and Mayo Wrist Score. SCA is a viable treatment option for patients with Kienbock disease. SCA offers reliable improvements in patient pain, grip strength, and patient-reported outcomes.

Adjunctive use of hypnosis for clinical pain: a systematic review and meta-analysis.

Systematic reviews suggest that stand-alone hypnotic suggestions may improve pain outcomes compared with no treatment, waitlist, or usual care. However, in clinical practice, hypnosis is often provided adjunctively with other interventions, which might have different effects than those reported in previous reviews. This systematic review aimed to summarize the analgesic effects of adjunctive hypnosis in adults with clinical pain. Seven databases (MEDLINE, Embase, PsycINFO, Emcare, SCOPUS, CENTRAL, Cochrane) were searched up to January 2024. Randomised controlled trials comparing the analgesic effects of adjunctive hypnosis (hypnosis + primary intervention) with those of the primary intervention alone were included. Meta-analyses (random-effects model) calculated mean differences (MD, [95% confidence intervals]) for pain intensity (0-100). Seventy studies were pooled in meta-analyses (n = 6078). Hypnosis adjunctive to usual care had a small additional analgesic effect (chronic pain: -8.2 [-11.8, -1.9]; medical procedures/surgical pain: -6.9 [-10.4, -3.3]; burn wound care: -8.8 [-13.8, -3.9]). Hypnosis adjunctive to education had a medium additional analgesic effect for chronic pain (-11.5 [-19.7, 3.3]) but not postsurgery pain (-2.0 [-7.8, 3.7]). When paired with psychological interventions, hypnosis slightly increased analgesia in chronic pain only at the three-month follow-up (-2 [-3.7, -0.3]). Hypnosis adjunctive to medicines had a medium additional analgesic effect for chronic pain (-13.2, [-22.5, -3.8]). The overall evidence certainty is very low; therefore, there is still uncertainty about the analgesic effects of adjunctive hypnosis. However, hypnosis adjunct to education may reduce pain intensity for chronic pain. Clarification of proposed therapeutic targets of adjunctive hypnosis to evaluate underlying mechanisms is warranted.
