Oxygen-ozone therapy for pain relief in patients with trapeziometacarpal osteoarthritis: a proof-of-concept study

PURPOSE

Trapeziometacarpal osteoarthritis (TMC-OA) is a prevalent hand disorder affecting a growing number of people worldwide. While a multidisciplinary approach might provide additional advantages, the analgesic and anti-inflammatory role of intra-articular oxygen-ozone (O2O3) injections combined with physical therapy is still unknown. To assess the impact of a multimodal therapeutic approach combining O2O3 injections with physical therapy in patients with TMC-OA.

MATERIALS AND METHODS

A prospective open-label study conducted in the Physical and Rehabilitation Medicine Unit of the "Renato Dulbecco" University Hospital of Catanzaro. We assessed patients with TMC-OA who had not responded to standard medical therapy. Participants received O2O3 therapy and targeted physical therapy for 4 weeks. Pain relief, muscle strength, and physical functioning were assessed at baseline and after 4, 12 and 24 weeks (respectively T0, T1, T2, and T3).

RESULTS

Seventeen patients with a mean age of 67.1 ± 6.1 years were included in the study. Short-term improvements in pain intensity were observed (T0: 6.221 ± 1.514; T1: 3.172 ± 1.1451; p < .001) and were maintained over a 24-week follow-up period (T0: 6.221 ± 1.514; T3: 4.393 ± 1.438; p: 0.006). Significant changes were reported also in terms of muscle strength and physical functioning. O2O3 therapy was well-tolerated with no adverse effects.

CONCLUSIONS

A combination of O2O3 injections and physical therapy might be considered in patients with TMC-OA. Further investigation is warranted to assess the effectiveness of O2O3 therapy in managing TMC-OA.

The use of medicaments in the management of symptomatic irreversible pulpitis: A community-based cohort study

AIM

To investigate patient outcomes from either pulpotomy or pulpectomy for the management of symptomatic irreversible pulpitis, with and without application of antibiotic/corticosteroid pastes in urgent primary dental care settings in the United Kingdom.

METHODOLOGY

All patients receiving intervention for symptomatic irreversible pulpitis in three different primary care settings were invited to participate. Pre-operatively, data regarding patients' numerical ratings scale (NRS), pain score (0-10), analgesic use, oral-health impact profile-14 (OHIP-14) and need for time away from work were collected. For 7 days post-operatively, participants recorded their NRS pain score, global rating of change score, medication use and their ability to work. Analysis used a mixed-effects model with post hoc Tukey's multiple comparisons test for continuous data and chi-squared or Fisher's exact test for categorical data. To test the effect of the corticosteroid/antibiotic paste, pulpectomy and pulpotomy groups were combined following Mantel-Haenszel stratified analysis or a weighted average of the difference between pulpotomy and pulpectomy with and without the use of corticosteroid/antibiotic paste. A binary composite score was constructed using pre- and post-operative data, whereby overall treatment success was defined as: (i) patients did not return for treatment due to pain by day seven; (ii) at day three, there was a 33% (or 2-points) reduction in NRS pain score; (iii) there was a change score of +3 in global rating; (iv) the patient was no longer using analgesia and able to return to work.

RESULTS

Eighty-five participants were recruited, with 83 completing follow up. Overall treatment success was 57%, with 25% of participants returning for more treatment due to inadequate pain relief. Overall treatment success did not differ between the two groups (p = .645), although patients self-reported greater improvement with an antibiotic/corticosteroid dressing for global rating of change (p = .015).

CONCLUSIONS

This study identified limited evidence of improved outcomes using antibiotic/corticosteroid dressings in the management of symptomatic irreversible pulpitis in the emergency setting. Further clinical research is needed to understand if these medications are beneficial in affording pain relief, above that of simple excision of irreversibly inflamed pulp tissue.

Does distal interphalangeal joint arthrodesis affect proximal interphalangeal joint arthroplasty outcomes in the same finger?

The purpose of this study was to analyse the 1-year outcomes after combining a surface replacing proximal interphalangeal joint arthroplasty and a distal interphalangeal screw arthrodesis and to compare the combined surgery with proximal interphalangeal joint arthroplasty alone. To obtain two groups with similar baseline data from our prospective registry, propensity score matching was used to match 23 fingers with the combined operations with 115 fingers with proximal interphalangeal joint arthroplasty alone. One year after surgery, the mean ranges of motion were 60° (95% CI: 53° to 67°) in the combined group and 63° (95% CI: 60° to 66°) in the control group and did not differ significantly. Grip strength, the brief Michigan Hand Questionnaire and pain also did not differ between the groups 1 year after surgery. All the proximal interphalangeal implants in patients treated with a distal interphalangeal screw arthrodesis remained in situ. Combining proximal interphalangeal joint arthroplasty with distal interphalangeal arthrodesis leads to 1-year outcomes that are similar to those achieved by proximal interphalangeal joint replacement alone.Level of evidence: III.

Assessment and treatment of nonsurgical thumb carpometacarpal joint osteoarthritis: A modified Delphi-based consensus paper of the American Society of Hand Therapists

BACKGROUND

While the literature is abundant on hand therapy assessment and treatment of nonsurgical thumb carpometacarpal (CMC) osteoarthritis (OA), clarity and uniformity are meager, making it a desirable diagnosis to establish expert consensus.

PURPOSE

This study aimed to ascertain if consensus exists for the assessment and treatment of nonsurgical management of thumb CMC OA in the hand therapy clinical setting.

STUDY DESIGN

This was a consensus paper via the modified Delphi approach.

METHODS

A modified Delphi method was used to determine consensus among an expert panel, including hand therapists and hand surgeons, via two online surveys. A consensus paper steering committee (from the American Society of Hand Therapist's research division) designed the surveys and analyzed responses. Consensus was established as 75% agreement among the expert panel. Demographic information was collected from the expert panel.

RESULTS

The expert panel included 34 hand therapists and seven hand surgeons. The survey response rates were 93.6% for the first survey and 90.2% for the second survey. Consensus recommendations were classified according to the World Health Organization categorization. These included evaluating the body structures for clinical signs/clinical testing and body functions for pain, range of motion for palmar abduction, radial abduction, opposition, and thumb metacarpal phalangeal flexion/extension, and grip and tripod pinch strength. Further consensus recommendations were for the assessment of function using a region-specific, upper extremity patient-reported outcome measure (activity and participation), environmental factors, outcome expectation, and illness perception within the patient's unique environmental and social contexts. Treatment recommendations included the use of an orthosis during painful activities, a dynamic stability program (stable C posture, release of tight adductors, and strengthening of stabilizers), patient education, joint protection techniques, adaptive equipment, and functional-based intervention.

CONCLUSIONS

The findings describe the consensus of a group of experts and provide a clinical reference tool on the hand therapy assessment and treatment of nonsurgical thumb CMC joint OA.

Patient-Reported Outcome Measurement and Minimal Clinically Important Difference for Hand Surgeons

Patient-reported outcome measurement (PROM) tools are used to evaluate health status and response to treatment and have been integral in the effort to improve the quality of care provided. Patient reported outcomes (PROs) have garnered additional attention since becoming a priority of the National Institutes of Health in the early part of this century, and their use in both clinical practice and research has subsequently increased. In the upper extremity, a variety of PRO instruments exist that can assist physicians in their ability to track and/or prognosticate outcomes, make comparisons between treatments as well as strengthen research methodologies, and help determine the value of care. A more complete interpretation of the clinical significance of patient-reported outcome measurements is informed by parameters such as minimal clinically important difference, substantial clinical benefit and patient acceptable symptom state.

Exploration of the methods of establishing the minimum clinical important difference based on anchors and their applications in the quality of life measurement scale QLICP-BR (V2.0) for breast cancer

Objective

The measurement of the quality of life (QOL) in patients with breast cancer can evaluate the therapeutic effects of medical treatments and help to provide reference for clinical decisions. The minimum clinically important difference (MCID) can be better used in clinical interpretation than the traditional statistical significance. Based on the anchors, a variety of ways including traditional and updated anchor-based methods were used to explore most suitable MCID, so that to find better interpretation on scores of the scale QLICP-BR(V2.0) (Quality of Life Instruments for Cancer Patients-Breast cancer).

Methods

According to the investigation data of breast cancer patients before and after treatment, the most relevant indicators in various domains of QLICP-BR (V2.0) was found as an anchor to statistically analyze the value of MCID, and three analysis methods of anchors were used: Traditional anchor-based method, ROC curve method, multiple linear regression model analysis. Anchors are divided into four standards according to the degree of change in the treatment effect: one grade difference (Standard A), at least one grade difference (Standard B), one grade better (Standard C), better (Standard D). The final MCID value is selected from different statistical methods and classification standards that are most suitable for clinicians to use.

Results

Using Q29 of the EORTC QLQ-C30 as an anchor has the highest correlation with each domain of QLICP. The order of magnitude of MCID values among the four standard groups is: standard A&lt; Standard C&lt; Standard B&lt; Standard D. The MCID value obtained by the ROC curve method is the most stable and is least affected by the sample size, and the MCID value obtained by the multiple linear regression model is the least. After comparisons and discussions, Standard C in the multiple linear regression model is used to determine the final MCID, which is the closest to other methods. After integer the MCID values of Physical domain (PHD), Psychological domain (PSD), Social domain (SOD), Common symptoms and side effect domain (SSD), Core/general module (CGD), Specific domain (SPD), Total score(TOT) can be taken as 15,10, 10, 11, 10, 9 and 9, respectively.

Conclusion

In the evaluation of the QOL of breast cancer patients, although the results of MCID values produced by different methods are different, the results are relatively close. The anchor-based methods make the results of MCID more clinically interpretable by introducing clinical variables, and clinicians and researchers can choose the appropriate method according to the research purpose.

The effectiveness of a mobile application-based programme for rehabilitation after total hip or knee arthroplasty: A randomised controlled trial

BACKGROUND

Total hip arthroplasty and total knee arthroplasty are widely performed worldwide. Patients undergoing total hip or knee arthroplasty are often discharged after a short hospital stay. Using information and communication technologies, such as mobile applications, to provide rehabilitation services remotely may be a strategy to support patients' postoperative recovery.

OBJECTIVE

This study aimed to evaluate the effectiveness of a rehabilitation programme delivered via a mobile application among Chinese patients after total hip or knee arthroplasty.

DESIGN

Randomised controlled trial.

SETTING

A teaching hospital in Shanghai, China.

PARTICIPANTS

Eighty-six patients who received a unilateral primary total hip or knee arthroplasty.

METHODS

The participants were recruited in the hospital and randomised into either the experimental or control group. Once discharged from the hospital, the control group (n = 43) received usual care, and the experimental group (n = 43) received usual care plus a 6-week mobile rehabilitation programme. Outcomes were assessed three times: the day before hospital discharge and 6 and 10 weeks after discharge. Primary outcomes were the changes in scores of self-efficacy and patient-reported physical function from baseline to 6 weeks post-discharge. Secondary outcomes included changes in scores of pain, depression, anxiety, and health-related quality of life. Data were analysed using generalised estimating equations.

RESULTS

At 6 weeks after hospital discharge, the experimental group showed statistically significant improvements compared to the control in scores of self-efficacy (adjusted mean difference = 0.72, 95% CI 0.31 to 1.14, P < .001) and patient-reported physical function (adjusted mean difference = 4.57, 95% CI 1.24 to 7.90, P = .007). The between-group difference in self-efficacy probably reached clinical significance. At week-10 follow-up, the experimental group had statistically significant improvements in scores of self-efficacy (adjusted mean difference = 0.64, 95% CI 0.33 to 0.95, P < .001), health-related quality of life (adjusted mean difference = 0.06, 95% CI 0.01 to 0.10, P = .018), anxiety (adjusted mean difference = -0.51, 95% CI -0.91 to -0.10, P = .015), and depression (adjusted mean difference = -0.37, 95% CI -0.66 to -0.08, P = .012). The between-group difference in self-efficacy and health-related quality of life may be clinically significant.

CONCLUSION

Mobile application-based rehabilitation demonstrated potentially positive effects on patients' self-efficacy, patient-reported physical function, health-related quality of life, and levels of anxiety and depression.

Psychometric properties of patient-reported outcome measures (PROMs) in wrist osteoarthritis: test-retest reliability and construct validity

BACKGROUND

Patient-reported outcome measures (PROMs) are frequently used to assess the effects of treatments in patients with wrist osteoarthritis (OA), but their psychometric properties have not been evaluated in this group of patients. Our aim was to evaluate the psychometric properties of the Numeric Rating Scale (NRS pain at rest, pain on motion without load, and pain on load), the Disabilities of the Arm, Shoulder and Hand (DASH) and the Patient Rated Wrist Evaluation (PRWE) questionnaires in patients with wrist OA regarding test-retest reliability and construct validity.

METHODS

The NRS, DASH and PRWE were self-administered by 50 patients (40 men and 10 women, mean age 66 years) in a postal survey on two occasions, two weeks apart. Test-retest reliability was evaluated by Kappa statistics and the Spearman rank correlation coefficients (rho) were calculated to evaluate construct validity.

RESULTS

The Kappa coefficients for DASH, PRWE and NRS pain on motion without load and NRS pain on load were > 0.90, 95% CI ranging from 0.84 to 0.98, while NRS pain at rest was 0.83, 95% CI 0.73-0.92. The construct validity of the PROMs was confirmed by three formulated hypotheses: a higher correlation between PRWE and NRS (rho 0.80-0.91, p < 0.001) was found, compared to DASH and NRS (rho 0.68-0.80, p < 0.001); the NRS pain on motion without load and NRS pain on load correlated more strongly to PRWE and DASH (rho 0.71-0.91, p < 0.001) compared to NRS pain at rest (rho 0.68-0.80) and a high correlation between PRWE and DASH was found (rho 0.86, p < 0.001).

CONCLUSIONS

The NRS, DASH and PRWE demonstrate excellent test-retest reliability and moderate to high construct validity in patients with wrist OA. These PROMs are highly related, but they also differ. Therefore, they complement each other in ensuring a comprehensive evaluation of perceived disability in wrist OA. As PRWE showed the highest test-retest reliability and the highest relation to the other PROMs, the sole use of the PRWE can be recommended in clinical practice.
