Long-term use of intrathecal baclofen reduces neuropathic pain and its interference with general activity in spinal cord injury individuals.

Long-term analgesic effect of intrathecal baclofen was reported in individuals with spinal cord injury. We conducted a prospective study to evaluate the effect of intrathecal baclofen on subtypes of neuropathic pain and its interference with general activity. Nine spinal cord injury individuals who presented with severe spasticity and moderate to severe neuropathic pain received intrathecal baclofen via an implanted pump. We applied the ASIA Impairment Scale to assess spinal cord injury severity. Neuropathic pain was evaluated by numerical rating scale, Neuropathic Pain Symptom Inventory, and Brief Pain Inventory. Evaluations were performed at baseline and after at least 6months of continuous intrathecal baclofen treatment. Intrathecal baclofen led to significant pain reduction as measured by numerical rating scale, Neuropathic Pain Symptom Inventory, and Brief Pain Inventory (p < 0.05). Improvements were significant for paroxysmal pain and dysesthesia and for pain interference with general activity, as assessed by the Brief Pain Inventory (p < 0.05). There was a significant relationship between the time since spinal cord injury and changes in paroxysmal pain as well as in the total Neuropathic Pain Symptom Inventory score (p < 0.05). The baclofen dose correlated also to the percentage changes in neuropathic pain improvement and sleep (p < 0.003). The present results provide evidence that intrathecal baclofen effectively reduces neuropathic pain, particularly paroxysmal pain and dysesthesia, and improves pain interference and overall well-being in individuals with spinal cord injury. Clinicians should be aware of this less well-known beneficial effect of intrathecal baclofen and should consider such a treatment option for better control of neuropathic pain in individuals with spinal cord injury.

Feasibility study of a novel digital template-guided flapless extraction for maxillary palatal impacted teeth.

With the increasing maturity of 3D printing technology, the application of digital guide template in the extraction of impacted teeth has become more sophisticated. However, for maxillary palatal deeply impacted teeth, there still exist significant clinical challenges. This experiment introduces a novel digital guide template and innovatively employs a flapless technique to explore a minimally invasive approach for the extraction of palatal deeply impacted teeth. This experiment included 40 patients diagnosed with palatal completely impacted teeth, randomly divided into an experimental group and a control group. The experimental group used the new digital guide template for flapless extraction, while the control group employed the traditional freehand flap technique. The experimental group can significantly reduce the localization time of palatally impacted teeth (P < 0.001), with total surgery times of 18.15 ± 4.88min and 22.00 ± 7.71min for the experimental and control groups, respectively (P = 0.067). Although there were no significant statistical differences between the two groups in terms of intraoperative bleeding, adjacent tooth damage, infection, or damage to nearby important anatomical structures, the experimental group showed significant improvements in postoperative pain (P < 0.05), swelling (P < 0.001), and patient satisfaction (P < 0.001) compared to the control group. Compared to traditional freehand flap surgery, flapless extraction of palatally impacted teeth guided by digital templates significantly reduces the localization time of impacted teeth and demonstrates notable advantages in some postoperative complications. Future studies with larger sample sizes are needed to substantiate the feasibility of this technique.

Percutaneous bone marrow concentrate and platelet products versus exercise therapy for the treatment of rotator cuff tears: a randomized controlled, crossover trial with 2-year follow-up

BackgroundSurgical repair is recommended for the treatment of high-grade partial and full thickness rotator cuff tears, although evidence shows surgery is not necessarily superior to non-surgical therapy. The purpose of this study was to compare percutaneous orthobiologic treatment to a home exercise therapy program for supraspinatus tears.MethodsIn this randomized-controlled, crossover design, participants with a torn supraspinatus tendon received either ‘BMC treatment’, consisting of a combination of autologous bone marrow concentrate (BMC) and platelet products, or underwent a home exercise therapy program. After three months, patients randomized to exercise therapy could crossover to receive BMC treatment if not satisfied with shoulder progression. Patient-reported outcomes of Numeric Pain Scale (NPS), Disabilities of the Arm, Shoulder, and Hand, (DASH), and a modified Single Assessment Numeric Evaluation (SANE) were collected at 1, 3, 6, 12, and 24 months. Pre- and post-treatment MRI were assessed using the Snyder Classification system.ResultsFifty-one patients were enrolled and randomized to the BMC treatment group (n = 34) or the exercise therapy group (n = 17). Significantly greater improvement in median ΔDASH, ΔNPS, and SANE scores were reported by the BMC treatment group compared to the exercise therapy group (-11.7 vs -3.8, P = 0.01; -2.0 vs 0.5, P = 0.004; and 50.0 vs 0.0, P < 0.001; respectively) after three months. Patient-reported outcomes continued to progress through the study’s two-year follow-up period without a serious adverse event. Of patients with both pre- and post-treatment MRIs, a majority (73%) showed evidence of healing post-BMC treatment.ConclusionsPatients reported significantly greater changes in function, pain, and overall improvement following BMC treatment compared to exercise therapy for high grade partial and full thickness supraspinatus tears.Trial registrationThis protocol was registered with www.clinicaltrials.gov (NCT01788683; 11/02/2013).

Abstract A017: Patient-reported experience related to aspects of quality of life after cystectomy from an exploratory focus group

Abstract Purpose: These exploratory focus groups examined patient experiences after having a cystectomy following bladder cancer. Methods: US individuals aged &amp;gt;50 years with self-reported diagnosis of non-muscle invasive bladder cancer (NMIBC) or muscle invasive bladder cancer (MIBC) who had undergone partial or radical cystectomy were recruited through a Patient Engagement Research Council program and invited to participate in an exploratory focus group (October 2022). Patients completed a prework survey on initial diagnosis, treatments, and how aspects of their life changed over time from pre-diagnosis, around the time of decision to undergo cystectomy, 90 days after cystectomy, and at present day. Patients attended gender-specific focus group sessions to discuss their patient journey, support needs, and how having a cystectomy affected their lives. Discussions were facilitated by a gender-matched moderator using a semi-structured discussion guide. Patients provided written informed consent and were compensated for their time. Key themes were identified by coding of audio transcripts and direct observations via the qualitative research analysis software MAXQDA. Results: Patients were six White adults (female n=3, male n=3, median age 68 years) with NMIBC (n=2) or MIBC (n=4) who underwent radical cystectomy between 2000 and 2020. Patients reported that bladder-sparing approaches were rarely introduced or discussed by their care team during their diagnostic journey, instead identifying disease eradication and pain improvement as primary drivers for choosing cystectomy. In the first 90 days post-surgery, patients reported that cystectomy negatively affected their ability to perform daily activities, mental health, and physical intimacy while adapting to a “new normal,” citing challenges with urinary diversion routes. Female patients cited a general lack of female-centric support (e.g. feminine hygiene and care education) as their support groups were mostly comprised of male patients focusing on male-centric issues (e.g., erectile dysfunction). In the present day, patients reported lower sex drive, satisfaction with body image, and physical intimacy. Patients called for more privacy consideration during medical examinations, better ostomy care support, increased awareness among healthcare professionals about the struggles patients face throughout their cystectomy journey, and improved education about available treatment options (including bladder preservation) and possible ramifications of cystectomy on all aspects of life (including sexual health and female-centric needs). Conclusions: Cystectomy can negatively affect patients’ lives, affecting their ability to participate in daily activities, mental health, and physical intimacy among those with NMIBC and MIBC. Patients expressed the need for holistic, long-term support (including awareness of treatment options, emotional support, and ostomy care) before, during, and after cystectomy.

Efficacy of massage versus massage with post isometric relaxation in temporomandibular disorders: a randomized controlled trial

BackgroundTemporomandibular joint disorder (TMD) is a common condition affecting the masticatory muscles and joint mobility.ObjectivesThe primary objective was to compare the effects of massage therapy alone and massage therapy combined with post-isometric relaxation exercises in patients with TMD for pain and maximal mouth opening.DesignAssessor-blinded randomized controlled trial.SettingSir Ganga Ram Hospital, Chaudhry Muhammad Akram Dental Hospital, Lahore Medical and Dental Hospital.SubjectsTemporomandibular joint disorder patients.InterventionGroup A (n = 23) received conventional treatment including massage and therapeutic exercises consecutively for 2 weeks. Group B (n = 23) received post-isometric relaxation technique along with conventional treatment for consecutive 2 weeks.Main measuresThe main outcome measures were pain and maximal mouth opening. Pain was measured using the Visual Analogue Scale (VAS) and maximal mouth opening (MMO) was measured using the TheraBite Scale.ResultsBoth groups demonstrated significant improvements in pain and MMO scores post-treatment. However, Group B (massage with post-isometric relaxation exercises) showed significantly better outcomes compared to Group A (massage alone). There was a statistically significant difference in post-treatment pain scores (P = 0.000) and MMO scores (P = 0.000) between the two groups.ConclusionThe results suggest that massage therapy combined with post-isometric relaxation is more effective than massage therapy alone in managing pain and improving mouth opening in TMD patients. The study provides evidence supporting the use of these therapies in TMD management.Trial registry numberNCT05810831. Date of registration/First submission: 15 March 2023.

Early Outcomes of Orthopedic Pre-surgical Patients Enrolled in an Intensive, Interprofessional Lifestyle Medicine Program to Optimize Health

Recently, lifestyle medicine (LSM) application has shown feasibility for musculoskeletal pain patients with co-existing lifestyle-related chronic diseases. This study describes early results of a LSM program for musculoskeletal patients with goals to optimize health prior to orthopedic surgery. Fifty-four patients (age: 61 ± 11 years; 39 [72%] females) completed the program from 3/8/22-12/1/23. Data included patient goals, utilization, goal attainment, and patient outcomes. Most patients (41/54 [76%]) enrolled with established surgical dates. Mean BMI was 43.2 ± 5.3 kg/m2, and 89% had ≥2 lifestyle-related chronic diseases. The majority reported impaired sleep (79%) and zero cumulative minutes of physical activity/week (57%). Mean program duration was 13 ± 8 weeks involving 5 ± 4 visits with members of the interprofessional team. Fifty-two (96%) patients successfully attained pre-program goals, and 49/54 (91%) met their surgical goal. Of the patients enrolled without surgical dates, 11/13 (85%) optimized their health and proceeded to surgery. Forty-two (78%) patients reported decreases in weight and BMI, averaging 11 ± 7 lbs and 1.8 ± 1.3 kg/m2, respectively. Rates of improvement in pain, PROMIS-10 physical and mental health, and PHQ-4 were 52%, 37%, 45%, and 47%, respectively. These data demonstrate the feasibility and effectiveness of a LSM program to address whole-person health optimization and enable orthopedic patients to improve lifestyle behaviors and proceed to orthopedic surgery.

Network Meta-analysis and Economic Evaluation of Neurostimulation Interventions for Chronic Non-surgical Refractory back Pain.

Different types of spinal cord stimulation (SCS) have now been evaluated for the management of chronic non-surgical refractory back pain (NSRBP). A direct comparison between the different types of SCS or between closed-loop SCS with conventional medical management (CMM) for patients with NSRBP has not been previously conducted, and therefore, their relative effectiveness and cost-effectiveness remain unknown. The aim of this study was to perform a systematic review, network meta-analysis (NMA) and economic evaluation of closed-loop SCS compared with fixed-output SCS and CMM for patients with NSRBP. Databases were searched to 8th September 2023. Randomised controlled trials of SCS for NSRBP were included. Results of studies were combined using fixed-effect NMA models. A cost-utility analysis was performed from the perspective of the UK National Health Service with results reported as incremental cost per quality-adjusted life-year (QALY). Closed-loop SCS resulted in statistically and clinically significant reductions in pain intensity (mean difference [MD] 32.72 [95% CrI 15.69-49.78]) and improvements in secondary outcomes compared to fixed-output SCS at 6-months follow-up. Compared to CMM, both closed-loop and fixed-output SCS result in statistically and clinically significant reductions in pain intensity (closed-loop SCS vs. CMM MD 101.58 [95% CrI 83.73-119.48]; fixed-output SCS versus CMM MD 68.86 [95% CrI 63.43-74.31]) and improvements in secondary outcomes. Cost-utility analysis shows that closed-loop SCS dominates fixed-output SCS and CMM, and fixed-output SCS also dominates CMM. Current evidence shows that closed-loop and fixed-output SCS provide more benefits and are cost-saving compared to CMM for patients with NSRBP.

Transitional Changes of Anxiety, Pain and Other Symptoms in Cancer Patients Admitted to a Palliative Care Unit, Evaluated Using the Support Team Assessment Schedule - Japanese Version.

Objective: Association between physical symptoms and psychosocial difficulties of cancer patients has been reported widely. Nevertheless, the effects of pain and other symptom control on anxiety in such patients have not been investigated well. We investigated the association of improvement of pain and other symptoms with patient anxiety, and assessed factors associated with improvement of such symptoms. Methods: Data of patients with advanced cancer admitted to a palliative care unit during August 2018 - June 2022 were analyzed retrospectively. Severity of pain, other symptoms, and anxiety was assessed by the Support Team Assessment Schedule Japanese version (STAS-J) administered at admission and after 2weeks. Patients' physical data, their Palliative Prognostic Index (PPI) at admission, and their overall survival were collected and recorded. Results: Data of 701 patients were analyzed. Improvement of pain or other symptoms after 2weeks was not associated with the PPI total score or actual survival (P = .105 and .999). Patients with higher anxiety on admission experienced improvement of pain or other symptoms more frequently (P = .005). Worsening of anxiety was observed less in patients who experienced improvement in pain or other symptoms after 2weeks (P = .027). Conclusion: Pain or other symptoms of patients with advanced cancer was improved irrespective of the general condition indicated with actual survival and prognosis-predictive factors. These findings suggest the importance of pain and other symptoms' improvement and its important roles in the management of patient psychosocial problems such as anxiety.

Medical Cannabis for Patients Over Age 50: A Multi-site, Prospective Study of Patterns of Use and Health Outcomes

Objective: Cannabis is being used as a therapeutic option by patients around the globe, and older patients represent a rapidly growing subset of this population. This study aims to assess the patterns of medical cannabis use in patients over 50 years of age and its effect on health outcomes such as pain, sleep, quality of life, and co-medication. Method: The Medical Cannabis in Older Patients Study (MCOPS) is a multi-site, prospective observational study examining the real-world impact of medical cannabis use on patients over age 50 under the guidance of a health care provider. The study included validated instruments, with treating physicians collecting detailed data on participant characteristics, medical cannabis and co-medication use, and associated impacts on pain, sleep, quality of life, as well as adverse events. Results: Inclusion criteria were met by 299 participants. Average age of participants was 66.7 years, and 66.2% of respondents identified as female. Approximately 90% of patients used medical cannabis to treat pain-related conditions such as chronic pain and arthritis. Almost all patients reported a preference for oral cannabis products (e.g., extracts, edibles) rather than inhalation products (e.g., flower, vapes), and most preferred oral formulations high in cannabidiol and low in tetrahydrocannabinol. Over the six-month study period, significant improvements were noted in pain, sleep, and quality of life measures, with 45% experiencing a clinically meaningful improvement in pain interference and in sleep quality scores. Additionally, nearly 50% of patients taking co-medications at baseline had reduced their use by the end of the study period, and quality of life improved significantly from baseline to M3 and from baseline to M6, with an incremental cost per quality-adjusted life-year (QALY) of $25,357.20. No serious adverse events (SAEs) were reported. Conclusions: In this cohort of older patients, most of whom suffered from pain-related conditions, medical cannabis seemed to be a safe and effective treatment. Most patients experienced clinically significant improvements in pain, sleep, and quality of life and reductions in co-medication. The cost per QALY was well below the standard for traditional pharmaceuticals, and no SAEs were reported, suggesting that cannabis is a relatively safe and cost-effective therapeutic option for adults dealing with age-related health conditions.

Upadacitinib in Active Non-radiographic Axial Spondyloarthritis: 1-Year Data From a Double-Blind, Randomized, Placebo-Controlled, Phase 3 Trial.

Upadacitinib improved the signs and symptoms of non-radiographic axial spondyloarthritis (nr-axSpA) versus placebo over 14 weeks in the primary analysis of the SELECT-AXIS 2 nr-axSpA study. Here, we evaluated the efficacy and safety of upadacitinib through 1 year in patients with nr-axSpA in SELECT-AXIS 2. Patients aged at least 18 years diagnosed with nr-axSpA who fulfilled the 2009 Assessment of SpondyloArthritis International Society (ASAS) classification criteria and were receiving stable background therapy were randomized to upadacitinib 15 mg once daily or placebo for the 52-week double-blind period. Efficacy was assessed using non-responder imputation incorporating multiple imputation (NRI-MI) and as-observed analyses for binary endpoints, and mixed-effects model repeated measures for continuous endpoints. Of 314 randomized patients, 259 (upadacitinib, n = 129; placebo, n = 130) completed 52 weeks of treatment. More patients receiving upadacitinib versus placebo achieved ≥40% improvement in ASAS at week 52 (63% vs 43%, NRI-MI; nominal P < 0.001). Similar treatment effects were observed for the achievement of axSpA Disease Activity Score inactive disease (33% v 11%, NRI-MI; nominal P < 0.001). Overall, patients receiving upadacitinib versus placebo showed greater improvement in disease activity, inflammation, pain, function, enthesitis, and quality of life through 52 weeks. Adverse events were generally comparable between the treatment groups. No opportunistic infections, malignancies, major adverse cardiovascular events, venous thromboembolic events, inflammatory bowel disease, or deaths were reported in those receiving upadacitinib. Treatment with upadacitinib showed sustained efficacy versus placebo with no new safety findings identified through 1 year. These results support the continued favorable benefit-risk profile of upadacitinib treatment for nr-axSpA.

Expression of cytokines at baseline correlate/predict in the disc the outcome of surgery after disc degeneration: A 12-month follow-up study.

Low back pain (LBP) is a highly prevalent condition that comprise a large portion of outpatient practice, challenging the diagnosis and treatment. However, the diagnostic tools are limited to clinical history, physical examination and imaging. Degenerative disc disease (DDD) is a significant cause of LBP, and emerging literature confirms the elevated levels of biomarkers in the discs. These biomarkers may serve as a tool for diagnosis, but may also be useful in predicting the treatment outcome. Here, we examine the expression of various cytokines on 1-year recovery from patients with LBP. Patient-reported outcome (PRO) in terms of pain intensity (VAS), disability (ODI), and quality of life (Eq-5D) is collected from 44 patients at baseline and 12 months after surgery to study the influence of baseline TNF-α, IL-1β, and IL-6 mRNA expression in both annulus fibrosus (AF) and nucleus pulposus (NP). Between baseline and follow-up, our cohort showed improvement in VAS back pain (p < 0.001), VAS leg pain (p < 0.001), ODI (p = 0.02), and Eq-5D (p = 0.01). Baseline levels of IL-1 β was positively correlated with VAS back pain scores in AF (p = 0.05) and NP (p = 0.01) at 1-year follow-up. TNF-α expression at baseline was also positively correlated to ODI scores (p = 0.01) at follow-up and inversely correlated to improvements in ODI score between baseline and follow-up, suggesting that high TNF-α expression at baseline is associated with poor outcomes from surgery. The results from our study support that TNF-α expression at baseline can serve as a very important predictor of treatment response from lumbar fusion surgery.

Potential Stem Cell Treatment for Common Hip Conditions: Osteoarthritis, Osteonecrosis and Gluteal Tendinopathy

Hip pathology, encompassing common conditions such as Osteoarthritis (OA), Osteonecrosis (ONFH) and gluteal tendinopathy, presents significant challenges in clinical management which often necessitate innovative treatment modalities. Stem cell therapy has emerged as a promising approach for addressing these complex hip conditions by promoting tissue regeneration and modifying disease progression. This paper aims to review the current literature on stem cell therapy for hip pathology, focusing on its application in OA, ONFH and gluteal tendinopathy. A comprehensive review of relevant studies and clinical trials was conducted by examining the safety, efficacy and potential mechanisms of action of stem cell therapy in hip conditions. Studies investigating the use of Bone Marrow-Derived Mesenchymal Stem Cells (BMMSCs), Adipose-Derived Mesenchymal Stem Cells (ADMSCs) and Tendon-Derived Stem Cells (TDSCs) were included in the analysis. The reviewed studies demonstrate promising outcomes of stem cell therapy in improving pain, functionality and halting disease progression in patients with hip OA. Intra-articular injections of MSCs have shown sustained benefits and arrested the progression of osteoarthritis. Stem cell therapy has also shown effectiveness in delaying the progression of ONFH, reducing femoral head collapse and decreasing the need for total hip replacement. Furthermore, in cases of gluteal tendinopathy, stem cell therapy has exhibited significant improvements in pain and functionality in a limited number of studies on the topic and also offers sustained relief in patients unresponsive to conventional treatments. Stem cell therapy holds immense potential as a safe and effective intervention for hip pathology and offers disease-modifying effects and sustained clinical benefits in these prevalent conditions. Further research is warranted to optimize treatment protocols, clarify mechanisms of action and validate long-term efficacy in larger cohorts.

Diet modification reduces pain and improves function in adults with osteoarthritis: a systematic review.

The effect of dietary modifications on pain and joint function in adults with osteoarthritis (OA) is an emerging area of study. This systematic review aimed to evaluate if adults with OA who consume diets with a higher proportion of plant phenols and omega-3 fatty acids would have less pain and improved joint function than those with a higher proportion of saturated fatty acids, omega-6 fatty acids and refined carbohydrates. Database searches of CINAHL (EBSCO), Clinical Trials (NIH-NLM), Cochrane Library (Wiley), Dissertation & Thesis Global (ProQuest), Embase (Elsevier), Medline (OVID), PubMed (NLM), Scopus (Elsevier), Web of Sciences (Clarivate) for clinical trials identified 7763 articles published between January 2015 and May 2023. After an independent review of the articles, seven randomised clinical trials and one nonrandomised clinical trial were included in the analysis. Because of the heterogeneity of the outcome measures, a meta-analysis was not possible. Participants who were instructed to consume high-phenol/high-omega-3 fatty acid diets reported significant improvements in pain and physical function scores. The greatest improvement was reported by those who consumed a diet that had the most omega-3 fatty acids. Because of the high risk of bias, the strength of the evidence is limited. However, there is evidence that counselling adults with OA to replace refined grains and processed foods with whole plant foods, fish and plant oils may have a favourable effect on pain and physical function. Routine follow-up care regarding these diet modifications may be necessary to ensure adherence to this therapy.

A Case of Olmsted Syndrome with Dramatic Response to Erlotinib.

A 63-year-old gentleman with Olmsted syndrome causing severe pain and quality of life impairments since birth was treated with erlotinib 100mg OD. This led to dramatic improvement in both pain and quality of life. Due to side effects the dose was reduced to 100mg three times a week which has maintained efficacy and side effects are now minimal.

Outcome comparison of meniscal allograft transplantation (MAT) and meniscal scaffold implantation (MSI): A systematic review.

Although numerous studies have reported successful clinical outcomes of Meniscal allograft transplantation (MAT) or Meniscal scaffold implantation (MSI), the difference between the outcome of MAT and MSI remains unclear. To compare the overall outcomes and survival rates of MAT and MSI, aiming to provide comprehensive evidence for determining the optimal treatment strategy for meniscal defects. A systematic review was performed via a comprehensive search of PubMed, Embase, and the Cochrane Library. Studies of MAT or MSI were included according to the inclusion and exclusion criteria. The Lysholm score was chosen as the primary outcome measure, while secondary outcomes encompassed Patient-reported Outcome Measures (PROMs), Return to Sports (RTS) rates, survival rates, and complication rates. The outcomes were stratified into two groups: MAT group and MSI group, followed by statistical comparison (P<0.05). The quality of the included studies was assessed by the Cochrane Risk of Bias 2 (RoB2) assessment tool for randomized controlled trials (RCTs) and the Coleman Methodology Score (CMS) for non-randomized controlled trials. A total of 3932 patients (2859 MAT, 1073 MSI) in 83 studies (51 MAT, 32 MSI) had the overall significant improvement in all clinical scores. The group MSI had higher Lysholm score of both preoperative (P=0.002) and postoperative (P<0.001) than group MAT; however, the mean improvements were similar between the two groups (P=0.105). Additionally, MSI had higher improvements of IKDC (P<0.001), KOOS symptom (P=0.010), KOOS pain (P=0.036), and KOOS ADL (P=0.004) than MAT. Interestingly, MAT had higher preoperative (P=0.018) and less postoperative VAS pain (P=0.006), which was more improved in MAT (P<0.001). Compared with MAT, MSI had higher 10-year survival rate (P=0.034), similar mid-term survival rate MAT (P=0.964), and lower complication rate (P<0.001). Both MAT and MSI could have good clinical outcomes after surgery with the similar improvement in Lysholm score. MSI had higher 10-year survival rate and less complications than MAT. IV, systematic review.

A PROSPECTIVE OBSERVATIONAL STUDY OF THUMB FUNCTION FOLLOWING FIRST CARPOMETACARPAL JOINT ARTHRODESIS

IntroductionDespite the rising popularity of 1st carpometacarpal joint (CMCJ) arthrodesis as one of the surgical options for basilar thumb arthritis, the available literature on this is poor. This study aims to investigate post-operative pinch and grip strength following 1st CMCJ arthrodesis, at a minimum of 1 year follow-up. Complication rates, range of motion and patient reported scores were also evaluated.MethodsA retrospective cohort (2012–2020) was used, which included patients who had arthrodesis performed by the Hands surgeons at Counties Manukau DHB. In a 15 minute visit, we took the measurements using our standard dynamometer and pinch gauge, and collected three questionnaires [QuickDASH, PRWHE, PEM]. For analysis, we compared our results to the preoperative measures, contralateral hand, and to a previous study on a similar cohort looking at thumb strength following trapeziectomy.Results42 arthrodesis were performed, and 24 were available for follow-up. The average follow-up time was 77 months and the average age was 51 years old. Overall, we found a statistically significant improvement in thumb strength following surgery. Mean preoperative grip strength was 21.4kg and 32.5kg postoperatively (= +11kg). Preoperative pinch strength was 5.5kg and 7kg postoperatively (= +1.5kg). These results were significantly higher compared to the trapeziectomy cohort. We also found an improvement in 1st CMCJ ROM post-operatively. 7 complications were reported (29.1%). 4 were metalware-related and 3 were non-union. QuickDASH score significantly improved from a median of 42.95 to 12.5 while PRWHE from 67.5 to 14.5. Overall patient satisfaction was 87.4%.Conclusion1st CMCJ arthrodesis leads to an improvement in thumb function, pain and range of movement and results in high patient satisfaction, and therefore should be recommended for younger patients who need a pain-free and strong thumb.

BIOPATCH GRAFTING OF LARGE OR RECALCATRANT OSTEOCHONDRAL DEFECTS OF THE TALUS

IntroductionLarge osteochondral defects (OCD) of the talus present a difficult management conundrum. We present a series of Maioregen xenograft patches applied through an open approach, early lessons from the technique and good early outcomes, in patients who are otherwise looking at ankle salvage techniques.Results16 patients underwent open patch procedures, performed by a single surgeon, over a 30 month period. 12 males, and 4 females with age at presentation from 21–48. The majority were young, male, in physical employment with active sporting interest. MoxFQ, and E5QD were collected preop, 3, 6, 12 month postoperatively. There were significant improvements in ROM, pain, and scores in the cohort. 3 cases returned to Theatre, 1 for a concern about late infection, which settled with good outcome, and a further 2 with metalwork / adhesions.ConclusionEarly results suggest that this patch technique may be useful in prolonging the longevity of the TTJ, where micro fracture has failed, or the lesion is so large that it would likely be futile. Patients rescoped demonstrated good integration of the patch material, with stability and functional improvement. There may be a place for this technique in the management of large lesions, particularly in young patients where preservation is desired over joint salvage.

The efficacy and real-world effectiveness of a diet low in fermentable oligo-, di-, monosaccharides and polyols in irritable bowel syndrome: A systematic review and meta-analysis

Background and AimsA diet low in fermentable oligo-, di-, monosaccharides, and polyols (LFD) has been shown to effectively reduce irritable bowel syndrome (IBS) symptoms. Effects resulting from real-world studies may differ from those seen in efficacy studies because of the diversity of patients in real-world settings. This systematic review and meta-analysis aimed to compare the effect of the LFD on reducing IBS symptoms and improving the quality of life (QoL) in efficacy trials and real-world studies. MethodsMajor databases, trial registries, dissertations, and journals were systematically searched for studies on the LFD in adults with IBS. Meta-analysis was conducted using a random effects model with standardized mean differences (SMD) and 95% confidence intervals (CI). Outcomes of interest were all patient-reported: stool consistency, stool frequency, abdominal pain, overall symptoms, adequate symptom relief, IBS-specific QoL and adherence to the LFD. ResultsEleven efficacy and 19 real-world studies were reviewed. The meta-analysis results for abdominal pain (SMD 0.35, 95% CI 0.16 to 0.54) and QoL (SMD 0.23, 95% CI -0.05 to 0.50) showed the LFD was beneficial in efficacy studies with no statistically significant results for stool frequency (SMD 0.71, 95% CI 0.34 to 1.07). Real-world studies found improvements in abdominal pain and QoL. Due to heterogeneity, no meta-analysis was done for stool consistency and overall symptoms. In these outcomes, results were mostly supportive of the LFD, but they were not always statistically significant. ConclusionsThe results of this systematic review and meta-analysis suggest the LFD improves outcomes compared to a control diet (efficacy studies) or baseline data (real-world studies). Because of diverse study designs and heterogeneity of results, a clear superiority of the LFD over control diets could not be concluded. There are no indications of an efficacy-effectiveness gap for the LFD in adults with IBS.

Quality-of-Life Outcomes in Oral Cancer Patients Reconstructed With Double Free Flaps: A Preoperative and Postoperative Assessment.

This study aimed to evaluate quality of life (QOL) in patients with locally advanced oral cancer who underwent surgical resection followed by simultaneous double free flap reconstruction. Institutional database was reviewed from 2015 to 2021 and prospectively collected University of Washington Quality of Life data that were extracted for patients who met the inclusion criteria. Mean, composite, and best percentage scores were computed. Wilcoxon signed rank test was used to analyze differences between groups. Thirteen patients completed the assessment, all of them being male with a mean follow-up of 2.2 ± 1.2 years. Most common double free flap combination was fibula osteoseptocutaneous flap and anterolateral thigh flap (n = 11). Improvement in pain (P = 0.01) domain score with decline in speech (P = 0.01) and taste (P = 0.02) was noted along with an overall decline in QOL (P = 0.001) after cancer diagnosis. A decrease in physical function was seen postoperatively. Chewing and saliva were the most cited postoperative patient-reported domain affecting QOL. In double free flap reconstructed patients, in the postoperative phase, pain scores improved, whereas speech and taste scores declined. The overall health-related QOL declined compared with before cancer diagnosis.
