With unrelenting SARS-CoV-2 variants, additional COVID-19 mitigation strategies are needed. Oral and nasal saline irrigation (SI) is a traditional approach for respiratory infections/diseases. As a multidisciplinary network with expertise/experience with saline, we conducted a narrative review to examine mechanisms of action and clinical outcomes associated with nasal SI, gargling, spray, or nebulization in COVID-19. SI was found to reduce SARS-CoV-2 nasopharyngeal loads and hasten viral clearance. Other mechanisms may involve inhibition of viral replication, bioaerosol reduction, improved mucociliary clearance, modulation of ENaC, and neutrophil responses. Prophylaxis was documented adjunctive to personal protective equipment. COVID-19 patients experienced significant symptom relief, while overall data suggest lower hospitalization risk. We found no harm and hence recommend SI use, as safe, inexpensive, and easy-to-use hygiene measure, complementary to hand washing or mask-wearing. In view of mainly small studies, large well-controlled or surveillance studies can help to further validate the outcomes and to implement its use., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Huijghebaert, Parviz, Rabago, Baxter, Chatterjee, Khan, Fabbris, Poulas and Hsu.)

Context: Osteopathic manipulative treatment (OMT) is utilized by clinicians to diagnose and treat a variety of musculoskeletal conditions including acute and chronic pain, and other medical conditions. Previous studies have examined attitudes of allopathic (MD) residents toward OMT and have implemented residency-based curricula; however, literature is lacking on the attitudes of MD students toward OMT., Objectives: The objective of this study was to determine MD students' familiarity with OMT and to evaluate their interest in an elective osteopathic curriculum., Methods: A 15-item online survey was electronically sent to 600 MD students at a large allopathic academic medical center. The survey assessed familiarity with OMT, interest in OMT and in participating in an OMT elective, educational format preference, and interest in pursuing primary care. Educational demographics were also collected. Descriptive statistics and Fisher's exact test were utilized for categorical variables, and nonparametric tests were utilized for the ordinal and continuous variables., Results: A total of 313 MD students submitted responses (response rate=52.1 %), of which 296 (49.3 %) responses were complete and utilized for analysis. A total of 92 (31.1 %) students were aware of OMT as a modality in treating musculoskeletal disorders. Among the respondents who indicated "very interested" in learning a new pain treatment modality, the majority: (1) observed OMT in a prior clinical or educational setting (85 [59.9 %], p=0.02); (2) had a friend or family member treated by a DO physician (42 [71.2 %], p=0.01); (3) were pursuing a primary care specialty (43 [60.6 %], p=0.02); or (4) interviewed at an osteopathic medical school (47 [62.7 %], p=0.01). Among those interested in developing some OMT competency, the majority: (1) were pursuing a primary care specialty (36 [51.4 %], p=0.01); (2) applied to osteopathic schools (47 [54.0], p=0.002); or (3) interviewed at an osteopathic medical school (42 [56.8 %], p=0.001). A total of 230 (82.1 %) students were somewhat or very interested in a 2-week elective course in OMT; among all respondents, hands-on labs were the preferred method for delivery of OMT education (272 [94.1 %])., Conclusions: The study found a strong interest in an OMT elective by MD students. These results will inform OMT curriculum development aimed at interested MD students and residents in order to provide them with OMT-specific theoretical and practical knowledge., (© 2023 the author(s), published by De Gruyter, Berlin/Boston.)

Introduction: Scholarly activity among family medicine physicians is an important element of military medical readiness, both in terms of required scholarship during training and ongoing scholarship to address ongoing and emergent operational medical threats. Most literature on barriers to scholarly activity are limited to training programs and lack an important element in overcoming barriers-their priority to physicians. This study seeks to address these gaps by identifying prioritized research training needs of military family medicine physicians at all levels of training and practice., Materials and Methods: An institutional review board (IRB)-approved, cross-sectional, online survey was conducted from January 22, 2019, to February 7, 2020, using a modified version of the Hennessy-Hicks Training Needs Analysis Questionnaire. Respondents ranked their perceived level of skill and need for training for 20 literature-based elements of research success. They also self-identified research experience, level of training, and service membership. One-way analysis of variance to 95% CI was used to compare differences in self-reported research experience, number of peer-reviewed publications, number of external grants, and number of IRB protocols among services (Army, Navy, and Air Force), primary roles (resident, faculty, clinician, and leadership), and gender. Chi-squared tests were used to compare proportional differences, also to 95% CI., Results: Of 124 respondents, most were members of the Air Force (46%), Navy (24%), or Army (13%), serving in clinician (40%) or faculty (32%) roles. Most respondents (67%) reported three or fewer publications and had never been a primary investigator or co-investigator on an external grant. Of the 34 respondents who identified as a faculty at some point in their career, 26 (77%) reported two or more peer-reviewed publications, and 20 (59%) had fewer than six publications. The faculty had significantly more research experience and peer-reviewed publications than residents, clinicians, or leaders (3.92 vs 2.19, 2.24, and 3.40, respectively, P < .001, η2 = 0.22; 5.11 vs 1.13, 2.12, and 4.33, respectively, P < .001, η2 = 0.25). Gender differences in priority ranking were found, but each gender identified the same top three training needs. Among the top 10 training needs for scholarly activity for military family medicine physicians, 7 may be addressed with specific training modules: (1) obtaining funding/grants for research, (2) accessing research resources (e.g., research administrators and other staff, information, equipment, money, and time), (3) establishing a relationship with research mentors, (4) undertaking health promotion studies, (5) designing a research study, (6) writing reports of your research studies, and (7) using technical equipment, including computer software, to find and organize published research or prepare manuscripts., Conclusions: Knowledge of military family medicine physicians' prioritized research training needs enables a focused approach to support an essential component of military medical readiness: primary care scholarship. Addressing these needs may begin with raising awareness of military primary care research network resources. Furthermore, a coordinated effort to develop specific training modules to address needs and ongoing research to identify, target training by audience need, and prioritize needs as they change over time are indicated to ensure that military family medicine physicians maintain and develop a flourishing culture of scholarly engagement., (Published by Oxford University Press on behalf of the Association of Military Surgeons of the United States 2021.

Objective: To systematically review the effectiveness of hypertonic dextrose prolotherapy (DPT) on pain intensity and physical functioning in patients with lateral elbow tendinosis (LET) compared with other active non-surgical treatments., Data Sources: Systematic search of Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, Web of Science, PubMed, Dimensions, Global Health, NHS Health Technology Assessment, Allied and Complementary Medicine, and OVID nursing database from inception to June 15, 2021, without language restrictions., Study Selection: Two reviewers independently identified parallel or crossover randomized controlled trials that evaluated the effectiveness of DPT in LET. The search identified 245 records; data from 8 studies (354 patients) were included., Data Extraction: Two reviewers independently extracted data and assessed included studies. The Cochrane Risk of Bias 2 tool was used to evaluate risk of bias. The Grading of Recommendation Assessment, Development, and Evaluation approach was used to assess quality of the evidence., Data Synthesis: Pooled results favored the use of DPT in reducing tennis elbow pain intensity compared with active controls at 12 weeks postenrollment, with a standardized mean difference of -0.44 (95% confidence interval, -0.88 to -0.01, P=.04) and of moderate heterogeneity (I 2 =49%). Pooled results also favored the use of DPT on physical functioning compared with active controls at 12 weeks, with Disabilities of the Arm, Shoulder and Hand scores achieving a mean difference of -15.04 (95% confidence interval, -20.25 to -9.82, P<.001) and of low heterogeneity (I 2 =0.0%). No major related adverse events have been reported., Conclusions: DPT is superior to active controls at 12 weeks for decreasing pain intensity and functioning by margins that meet criteria for clinical relevance in the treatment of LET. Although existing studies are too small to assess rare adverse events, for patients with LET, especially those refractory to first-line treatments, DPT can be considered a nonsurgical treatment option in carefully selected patients. Further high-quality trials with comparison with other injection therapies are needed., (Copyright © 2022 The Authors. Published by Elsevier Inc. All rights reserved.)

Adults with attention deficit hyperactivity disorder (ADHD) have shown higher infection rates and worse outcomes from COVID-19. Stimulant medications are prescribed as the first-line treatment for ADHD in adults and mitigate risk of negative ADHD-related health outcomes, but little is known about the association between stimulant medications and COVID-19 outcomes. The objective of this study was to assess the risks of severe COVID-19 outcomes among people with ADHD who were prescribed stimulant medications versus those who were not. This retrospective cohort study used electronic health records in the TriNetX research database. We assessed records of adults with ADHD diagnosed with COVID-19 between January 1, 2020 and June 30, 2021. The stimulant cohort consisted of 28,011 people with at least one stimulant prescription; the unmedicated cohort comprised 42,258 people without prescribed stimulants within 12 months prior to their COVID infection. Multiple logistic regression modeling was utilized to assess the presence of critical care services or death within 30 days after the onset of COVID diagnoses, controlling for patient demographics, and comorbid medical and mental health conditions. The stimulant cohort was less likely to utilize emergency department, hospital, and intensive care services than the unmedicated cohort, and had significantly lower 30-day mortality. Further research, including prospective studies, is needed to confirm and refine these findings., (Copyright © 2022 Elsevier Inc. All rights reserved.)

Background: Osteopathic manipulative treatment (OMT) may improve outcomes during COVID-related respiratory distress - the most common cause of death from novel coronavirus (SARS-CoV-2). Outcomes from OMT treatments of respiratory distress during the COVID-19 pandemic have not been reported., Objective: Assess adjunctive OMT in hospitalized patients with SARS-CoV-2 and respiratory distress., Design: Feasibility oriented retrospective observational cohort study., Setting: COVID-19 (non-ICU) ward in a tertiary academic medical center., Methods: Inpatients received daily OMT treatments of rib raising, abdominal diaphragm doming, thoracic pump and pedal pump. Primary outcomes were procedural acceptance, satisfaction, side effects, and adverse events. Secondary outcomes were patient-reported clinical change after therapy; number of hospital days; need during hospitalization for high-flow oxygen, C-PAP/BiPAP or intensive care; need for supplementary oxygen at discharge; and discharge disposition., Participants: Hospitalized adults with SARS-CoV-2 infection and respiratory distress., Results: OMT (n = 27) and Control (n = 152) groups were similar in demographics and most laboratory studies. 90% of patients accepted OMT and reported high satisfaction (4.26/±0.71 (maximum 5)), few negative effects, no adverse events, and positive clinical change (5.07 ± 0.96 (maximum 7)). Although no significant differences were found in secondary outcomes, OMT patients trended towards fewer hospital days than Controls ( p  = 0.053; Cohen's d = 0.22), a relationship that trended towards correlation with number of co-morbidities (p = 0.068)., Conclusion: Hospitalized patients with respiratory distress and COVID-19 reported acceptance, satisfaction, and greater ease of breathing after a four-part OMT protocol, and appear to have a shorter length of hospitalization. Randomized controlled trials are needed to confirm these results., (© 2022 Elsevier Ltd. All rights reserved.)

Objective: Hypertonic dextrose (HD) injections (prolotherapy) for osteoarthritis are reported to reduce pain. Cartilage regeneration is hypothesized as a mechanism. This in vitro study identifies an HD concentration that stimulates chondrogenic cells to increase metabolic activity and assesses whether this concentration affects collagen deposition and proliferation., Design: ATDC5 chondrogenic cells were cultured in normoglycemic DMEM/F12 medium, treated with concentrations of HD (4-400 mM), and assessed with PrestoBlue. Advanced light microscopy was used to conduct live imaging of collagen deposition through second harmonic generation microscopy (SHG) and proliferation via 2-photon excitation microscopy. Proliferation was additionally assessed with hemocytometer counts., Results: A linear regression model found that, relative to the 4 mM baseline control, cells treated with 200 mM had a higher mean absorbance ( P = 0.023) and cells treated with 250 mM were trending toward a higher mean absorbance ( P = 0.076). Polynomial regression interpolated 240 mM as producing the highest average absorbance. Hemocytometer counts validated 250 mM as stimulating proliferation compared with the 4 mM control ( P < 0.01). A concentration of 250 mM HD led to an increase in collagen deposition compared with that observed in control ( P < 0.05). This HD concentration also led to increases in proliferation of ATDC5 cells relative to that of control ( P < 0.001)., Conclusions: A 250 mM HD solution appears to be associated with increased metabolic activity of chondrocytes, increased collagen deposition, and increased chondrocyte proliferation. These results support clinical prolotherapy research suggesting that intra-articular HD joint injections reduce knee pain. Further study of HD and cellular processes is warranted.

Aims: The aim of the present study was to explore: (1) the feasibility of using color and pain drawing to describe pain; (2) the cultural appropriateness of pain body diagram (PBD); and (3) the cultural meaning of colors used in pain expression within one cultural group-the Hmong residing in the United States., Design: A qualitative-descriptive study., Methods: Data were collected sequentially in two phases with different Hmong participants from a Midwestern city using (1) focus groups to determine colors used for pain intensity and qualities along with preferences for drawing versus using the PBD; and (2) individual interviews to determine pain-related meanings of colors and cultural appropriateness of PBDs. Interviews were recorded, transcribed, and analyzed using summative and directed content analyses., Results: Of 67 participants, 73% were female, the average age was 53.7±14.9 years, and 67% received Medicaid. In Phase I, most participants were unable to draw their pain on a blank page and preferred using a PBD. Most could select colors for pain intensity levels, with white and red indicating no pain and severe pain, respectively. In Phase II, white, red, and black had cultural meanings related to pain while colors such as yellow, orange, and blue had personal meanings. All participants perceived the PBD to be culturally appropriate., Conclusions: The study's findings have implications for how to use colors in pain communication and confirm that PBDs can be used with Hmong patients., (Copyright © 2021 Elsevier Ltd.

After 40 years of attributing high rates of physician career dissatisfaction, attrition, alcoholism, divorce and suicide to 'burnout', there is growing recognition that these outcomes may instead be caused by moral injury. This has led to a debate about the relative diagnostic merits of these two terms, a recognition that interventions designed to treat burnout may be ineffective, and much perplexity about how-if at all-this changes anything.The current research seeks to develop the construct of moral injury outside military contexts, generate more robust validity tests and more fully describe and measure the experiences of persons exposed to moral harms. Absent from the literature is a mechanism through which to move from the collective moral injury experience of physicians to a systematic change in the structure of medical practice. To address this, after providing a brief history, definitions and contrasts between burnout, moral distress and moral injury, we review the interplay of moral and ethical codes in the context of moral injury. We conclude by suggesting that professional associations can potentially prevent moral injury by providing protections for physicians within their codes of ethics., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2021.

Background: Little is known about the relevance of existing pain scales for patients with limited English proficiency (LEP)., Aims: To determine the ranking and perceptions of four pain intensity scales in LEP Hmong., Design: A sequential mixed-method study., Settings: A Midwestern city, USA., Participants/subjects: Eight-four Hmong aged 19 to 80 years old., Methods: Participants ranked four pain intensity scales-the Red Gradation Scale, the Black Gradation Scale, the Wong-Baker Faces Pain Rating Scale, and the Faces Pain Scale - Revised- using Likert responses of 1 (most) to 4 (least) on the following factors: the extent to which they liked the scale, perceived it to be accurate, and preferred to use it in clinical settings. A follow-up interview asked participants' scale selection decisions. Spearman correlations and ordered logistic regression assessed the scale rankings. Thematic analysis was used to analyze the qualitative data., Results: Participants ranked the Wong-Baker Faces Pain Rating Scale as the most liked (3.22 ± 0.95, 50.6%), the most accurate (3.13 ± 0.93, 44.6%), and the most preferred (3.14 ± 1.03, 49.4%). Older Age predicted the selection of this scale. Six themes influenced participants' ranking decisions: the visual clarity of the scale, their experience or familiarity with the scale, the cultural connotations of pain, the type of emotions provoked by scale, the alignment of pain expression reflected in the scale, and the literacy concerns that the scale addressed., Conclusions: The Wong-Baker Faces could be appropriate for older Hmong. Further validity and reliability studies are needed for the Wong-Baker Faces., (Copyright © 2020. Published by Elsevier Inc.)

Background: Osteoarthritis is common and debilitating. Evidence-based care exists; there is a gap between recommended and received are. Multimodal treatment is recommended, with unknown effectiveness. We report pilot feasibility data for a new university-based clinic providing multimodal care for knee and hip osteoarthritis (KHOA)., Methods: Quality-improvement case series with the first 50 patients. A multidisciplinary team provided care. Feasibility outcomes included treatment duration, patient adherence, provision of guideline-recommended care, and satisfaction. Secondary outcomes included self-reported and objectively assessed patient measures., Results: Fifty patients (59±10.5 years, 32 female) received guideline-recommended care; 40 adhered to 3.83±2.21 follow-up visits over 12.24±7.79 months; satisfaction was high. Objectively assessed outcomes improved, but self-reported outcomes did not., Discussion: Early data suggest multimodal care for knee and hip osteoarthritis is feasible and may be associated with improved outcomes., (Copyright© Board of Regents of the University of Wisconsin System and The Medical College of Wisconsin, Inc.)

Chronic musculoskeletal pain and disability dramatically reduce quality and quantity of life worldwide, disproportionately so in low- and middle-income countries. Complementary therapies not typically learned in conventional medical training have much to offer but are under-utilized. Prolotherapy is an injection-based complementary therapy supported by high-quality evidence for osteoarthritis, tendinopathy, and low back pain. Prolotherapy addresses causes of pain and disability at the tissue level, is straightforward to learn, and relies on common, inexpensive material, and requires no refrigeration. Not-for-profit organizations are delivering prolotherapy to underserved patients in low- and middle-income countries through service-learning projects., (Copyright © 2019 Elsevier Inc.

Aim: Platelet Rich Plasma (PRP) is an emerging therapy for knee osteoarthritis (KOA). Studies have evaluated the effectiveness of intra-articular PRP, which ignores extra-articular tissue dysfunction and may provide incomplete treatment of KOA. The study aimed to pilot test a leukocyte-rich (mononuclear cells) PRP injection protocol for primary KOA, which consisted of single intra-articular injection and extra-articular injections on the medial coronary and medial collateral ligaments., Methods: A prospective 26-week single-arm uncontrolled feasibility pilot study. Patients (N = 12) with primary KOA as defined by the American Rheumatology Association, with moderate to severe medial knee pain which failed conservative management, were recruited in a university primary care clinic and received a single session of PRP injection in week 1. The primary outcome was the feasibility of the protocol at 26 weeks as defined by rates of recruitment, compliance, retention, dropout, side effects or adverse events; and treatment satisfaction. Secondary outcomes included the Western Ontario McMaster University Osteoarthritis Index, the Intermittent and Constant Osteoarthritis Pain total and subscales, objective physical function tests and EuroQol-5D., Results: Twelve of 40 potential patients were recruited in 3 months period (recruitment rate 30%, x2 = 3.33, P = 0.068). All participants adhered to the protocol and completed the follow up assessment with no dropouts (dropout rate 0%, X2= 2.67, P = 0.103). Satisfaction was high; no related adverse events were reported. Most secondary outcomes showed statistically significant improvement., Conclusions: Concomitant intra-articular and extra-articular PRP injections were feasible and produced preliminary favourable outcomes., (Copyright © 2019 Elsevier B.V.

Purpose of Review: Osteoarthritis and overuse tendinopathy are common chronic conditions of high societal and patient burden. The precise etiology of pain and disability in both conditions is multifactorial and not well understood. Patients are often refractory to conservative therapy. The development of new therapeutic options in both conditions is a public health priority. Prolotherapy is an injection-based outpatient regenerative therapy for chronic musculoskeletal conditions, including osteoarthritis and tendinopathy. The authors reviewed the basic science and clinical literature associated with prolotherapy for these conditions., Recent Findings: Systematic review, including meta-analysis, and randomized controlled trials suggest that prolotherapy may be associated with symptom improvement in mild to moderate symptomatic knee osteoarthritis and overuse tendinopathy. Although the mechanism of action is not well understood and is likely multifactorial, a growing body of literature suggests that prolotherapy for knee osteoarthritis may be appropriate for the treatment of symptoms associated with knee osteoarthritis in carefully selected patients who are refractory to conservative therapy and deserves further basic and clinical science investigation for the treatment of osteoarthritis and tendinopathy.

Background: Dextrose injection is reported to improve knee osteoarthritis (KOA)-related clinical outcomes, but its effect on articular cartilage is unknown. A chondrogenic effect of dextrose injection has been proposed., Objective: To assess biological and clinical effects of intra-articular hypertonic dextrose injections (prolotherapy) in painful KOA., Design: Case series with blinded arthroscopic evaluation before and after treatment., Setting: Physical medicine and day surgery practice., Participants: Symptomatic KOA for at least 6 months, arthroscopy-confirmed medial compartment exposed subchondral bone, and temporary pain relief with intra-articular lidocaine injection., Intervention: Four to 6 monthly 10-mL intra-articular injections with 12.5% dextrose., Main Outcome Measures: Visual cartilage growth assessment of 9 standardized medial condyle zones in each of 6 participants by 3 arthroscopy readers masked to pre-/postinjection status (total 54 zones evaluated per reader); biopsy of a cartilage growth area posttreatment, evaluated using hematoxylin and eosin and Safranin-O stains, quantitative polarized light microscopy, and immunohistologic cartilage typing; self-reported knee specific quality of life using the Western Ontario McMaster University Osteoarthritis Index (WOMAC, 0-100 points)., Results: Six participants (1 female and 5 male) with median age of 71 years, WOMAC composite score of 57.5 points, and a 9-year pain duration received a median of 6 dextrose injections and follow-up arthroscopy at 7.75 months (range 4.5-9.5 months). In 19 of 54 zone comparisons, all 3 readers agreed that the posttreatment zone showed cartilage growth compared with the pretreatment zone. Biopsy specimens showed metabolically active cartilage with variable cellular organization, fiber parallelism, and cartilage typing patterns consistent with fibro- and hyaline-like cartilage. Compared with baseline status, the median WOMAC score improved 13 points (P = .013). Self-limited soreness after methylene blue instillation was noted., Conclusions: Positive clinical and chondrogenic effects were seen after prolotherapy with hypertonic dextrose injection in participants with symptomatic grade IV KOA, suggesting disease-modifying effects and the need for confirmation in controlled studies. Minimally invasive arthroscopy (single-compartment, single-portal) enabled collection of robust intra-articular data., Level of Evidence: IV., (Copyright © 2016 American Academy of Physical Medicine and Rehabilitation.

Prolotherapy involves the injection of nonbiologic solutions, typically at soft tissue attachments and within joint spaces, to reduce pain and improve function in painful musculoskeletal conditions. A variety of solutions have been used; dextrose prolotherapy is the most rigorously studied and is the focus of this review. Although the mechanism of action is not clearly known, it is likely to be multifactorial. Data on effectiveness for temporomandibular dysfunction are promising but insufficient for recommendations. Research on the mechanism of action and clinical effects of dextrose prolotherapy are under way., (Copyright © 2016 Elsevier Inc. All rights reserved.)

Background: Capsaicin specifically activates, and then gradually exhausts, the transient receptor potential vanilloid type 1 (TRPV1) receptor, a key receptor in neuropathic pain. Activation of the TRPV-1 receptor is accompanied by burning pain. A natural substance or medication that can reduce the burning pain resulting from capsaicin application may have therapeutic potential in neuropathic pain., Objective: To assess the pain-relieving effects of a mannitol-containing cream in a capsaicin-based pain model., Design: Randomized, placebo-controlled, double-blind clinical trial., Setting: Outpatient pain clinic., Participants: Twenty-five adults with pain-free lips., Methods: Capsaicin .075% cream was applied to both halves of each participant's upper lip, inducing pain via stimulation of the transient receptor potential vanilloid 1 (TRPV1, capsaicin) receptor, then removed after 5 minutes or when participants reported a burning pain of 8/10, whichever came first. A cream containing mannitol and the same cream without mannitol (control) were then immediately applied, 1 on each side of the lip, in an allocation-masked manner., Outcome Measures: Participants self-recorded a numeric rating scale (NRS, 0-10) pain score for each side of the lip per minute for 10 minutes. A t-test was performed to evaluate the pain score change from baseline between each side of the lip at each recording. Area under the curve (AUC) analysis was used to determine the overall difference between groups., Results: Participants reached a capsaicin-induced pain level of 7.8 ± 1.0 points in 3.3 ± 1.6 minutes that was equal on both sides of the lip. Both groups reported progressive diminution of pain over the 10-minute study period. However, participants reported significantly reduced pain scores on the mannitol cream half-lip compared to control at 3 through 10 minutes (P < .05) and in AUC analysis (P < .001)., Conclusions: Mannitol cream reduced self-reported pain scores in a capsaicin pain model more rapidly than a control cream, potentially via a TRPV1 receptor effect., (Copyright © 2015 American Academy of Physical Medicine and Rehabilitation.

Objective: To assess the relation between knee osteoarthritis (KOA)-specific quality of life (QOL) and intra-articular cartilage volume (CV) in participants treated with prolotherapy. KOA is characterized by CV loss and multifactorial pain. Prolotherapy is an injection therapy reported to improve KOA-related QOL to a greater extent than blinded saline injections and at-home exercise, but its mechanism of action is unclear., Design: Two-arm (prolotherapy, control), partially blinded, controlled trial., Setting: Outpatient., Participants: Adults with ≥3 months of symptomatic KOA (N=37)., Interventions: Prolotherapy: 5 monthly injection sessions;, Control: blinded saline injections or at-home exercise., Main Outcome Measures: Primary: KOA-specific QOL scores (baseline, 5, 9, 12, 26, and 52wk; Western Ontario and McMaster University Osteoarthritis Index). Secondary: KOA-specific pain, stiffness, function (Western Ontario McMaster University Osteoarthritis Index subscales), and magnetic resonance imaging-assessed CV (baseline, 52wk)., Results: Knee-specific QOL improvement among prolotherapy participants exceeded that among controls (17.6±3.2 points vs 8.6±5.0 points; P=.05) at 52 weeks. Both groups lost CV over time (P<.05); no between-group differences were noted (P=.98). While prolotherapy participants lost CV at varying rates, those who lost the least CV ("stable CV") had the greatest improvement in pain scores. Among prolotherapy participants, but not control participants, the change in CV and the change in pain (but not stiffness or function) scores were correlated; each 1% CV loss was associated with 2.7% less improvement in pain score (P<.05)., Conclusions: Prolotherapy resulted in safe, substantial improvement in KOA-specific QOL compared with control over 52 weeks. Among prolotherapy participants, but not controls, magnetic resonance imaging-assessed CV change (CV stability) predicted pain severity score change, suggesting that prolotherapy may have a pain-specific disease-modifying effect.

Study Design: Case-Control., Introduction: Although it is well known that grip strength is adversely affected by lateral epicondylosis (LE), the effect of LE on rapid grip force generation is unclear., Purpose of the Study: To evaluate the effect of LE on the ability to rapidly generate grip force., Methods: Twenty-eight participants with LE (13 unilateral and 15 bilateral LE) and 13 healthy controls participated in this study. A multiaxis profile dynamometer was used to evaluate grip strength and rapid grip force generation. The ability to rapidly produce force is composed of the electromechanical delay and rate of force development. Electromechanical delay is defined as the time between the onset of electrical activity and the onset of muscle force production. The Patient-rated Tennis Elbow Evaluation (PRTEE) questionnaire was used to assess pain and functional disability. Magnetic resonance imaging was used to evaluate tendon degeneration., Results: LE-injured upper extremities had lower rate of force development (50 lb/sec, confidence interval [CI]: 17, 84) and less grip strength (7.8 lb, CI: 3.3, 12.4) than nonnjured extremities. Participants in the LE group had a longer electromechanical delay (- 59% , CI: 29, 97) than controls. Peak rate of force development had a higher correlation (r = 0.56; p<0.05) with PRTEE function than grip strength (r = 0.47; p<0.05) and electromechanical delay (r = 0.30; p>0.05) for participants with LE. In addition to a reduction in grip strength, those with LE had a reduction in rate of force development and an increase in electromechanical delay., Conclusions: Collectively, these changes may contribute to an increase in reaction time, which may affect risk for recurrent symptoms. These findings suggest that therapists may need to address both strength and rapid force development deficits in patients with LE., Level of Evidence: 3B., (Copyright © 2012 Hanley & Belfus.

Objective: The purpose of this article is to detail the biology of platelet-rich plasma (PRP), critically review the existing literature, and discuss future research applications needed to adopt PRP as a mainstay treatment method for common musculoskeletal injuries., Conclusion: Any promising minimally invasive therapy such as PRP deserves further investigation to avoid surgery. Diagnostic imaging outcome assessments, including ultrasound-guided needle precision, should be included in future investigations.

Context: Upper respiratory conditions are common and have a significant impact on patient quality of life, medical resource expenditure, and antibiotic use. Saline nasal irrigation (SNI) is an adjunctive therapy for upper respiratory conditions; clinical studies suggest that use of SNI may be effective for symptoms of upper respiratory conditions, and its popularity seems to be growing. The prescribing patterns of physicians regarding SNI have not yet been studied., Objective: To assess the use among family physicians in Wisconsin of SNI, determine how and for which conditions they recommend SNI, and the degree to which they experience clinical success with SNI., Method: This was assessed by an electronic questionnaire of 330 practicing family physicians in the Wisconsin Academy of Family Physicians and Wisconsin Research and Education Network., Results: Analysis showed 286 of 330 respondents (87%) have used SNI as adjunctive care for a variety of upper respiratory conditions including chronic rhinosinusitis (91%), acute bacterial rhinosinusitis (67%), seasonal allergic rhinitis (66%), viral upper respiratory infection (59%), other allergic rhinitis (48%), irritant-based congestion (48%), and rhinitis of pregnancy (17%). Respondents also reported having used SNI prior to antibiotics for acute bacterial rhinosinusitis (77%). Use patterns varied regarding type of SNI administration, dosing frequency, saline concentration, and patient education., Conclusions: This questionnaire-based study suggests that SNI is used by family physicians for a variety of upper respiratory conditions though recommendation and patient education styles, dosing schedules, and solution types vary.

Background: Prolotherapy is an alternative therapy for chronic musculoskeletal injury including joint laxity. The commonly used injectant, D-glucose (dextrose), is hypothesized to improve ligament mechanics and decrease pain through an inflammatory mechanism. No study has investigated the mechanical effects of prolotherapy on stretch-injured ligaments., Hypotheses: Dextrose injections will enlarge cross-sectional area, decrease laxity, strengthen, and stiffen stretch-injured medial collateral ligaments (MCLs) compared with controls. Dextrose prolotherapy will increase collagen fibril diameter and density of stretch-injured MCLs., Study Design: Controlled laboratory study., Methods: Twenty-four rats were bilaterally MCL stretch-injured, and the induced laxity was measured. After 2 weeks, 32 MCLs were injected twice, 1 week apart, with either dextrose or saline control; 16 MCLs received no injection. Seven uninjured rats (14 MCLs) were additional controls. Two weeks after the second injection, ligament laxity, mechanical properties (n = 8), and collagen fibril diameter and density (n = 3) were assessed., Results: The injury model created consistent ligament laxity (P < .05) that was not altered by dextrose injections. Cross-sectional area of dextrose-injected MCLs was increased 30% and 90% compared with saline and uninjured controls, respectively (P < .05). Collagen fibril diameter and density were decreased in injured ligaments compared with uninjured controls (P < .05), but collagen fibril characteristics were not different between injured groups., Conclusion: Dextrose injections increased the cross-sectional area of MCLs compared with saline-injected and uninjured controls. Dextrose injections did not alter other measured properties in this model., Clinical Relevance: Our results suggest that clinical improvement from prolotherapy may not result from direct effects on ligament biomechanics.

Background: Rhinosinusitis is a common, expensive disorder with a significant impact on patients' quality of life. Chronic sinus symptoms are associated with allergic rhinitis, asthma, and nasal polyposis. Saline nasal irrigation is an adjunctive therapy for rhinosinusitis and sinus symptoms. Prior studies suggest that hypertonic saline nasal irrigation (HSNI) may be effective for symptoms associated with allergy, asthma, and nasal polyposis., Objective: To assess the degree to which subjects using nasal irrigation for chronic sinus symptoms also reported improvements in symptoms related to allergy, asthma, or nasal polyposis., Design: Qualitative study using in-depth long interviews of 28 participants in a prior qualitative nasal irrigation study. All participants were receiving daily nasal irrigation., Results: Transcripts of interviews were systematically examined. Twelve of 21 subjects with allergic rhinitis spontaneously reported that HSNI improved symptoms. Two of 7 subjects with asthma and 1 of 2 subjects with nasal polyposis reported a positive association between HSNI use and asthma or nasal polyposis symptoms. Transcript content was organized into themes that included: (1) HSNI resulted in improvement of allergic rhinitis and asthma symptoms, and (2) HSNI should be used for symptoms of allergic rhinitis., Conclusions: This hypothesis-generating study offers qualitative evidence that suggests patients with frequent rhinosinusitis and daily sinus symptoms, symptoms of concomitant allergic rhinitis, asthma, or polyposis may improve with HSNI. The parent studies offer strong evidence that HSNI is an effective adjunctive treatment for symptoms of chronic rhinosinusitis. Larger prospective studies are needed in patients with these diagnoses.

Background: Clinical medicine and healthcare policy are increasingly guided by randomized controlled trials, which in turn are dependent on the validity of placebo control. It is important to understand the effects of placebo control on outcome measurement, especially for assessment of symptoms and functional impairments where subjectivity, expectancy, and motivation may significantly impact outcome evaluation. This paper describes the rationale and methodology of a trial designed to evaluate placebo effects related to taking pills and to compare these with effects attributable to standard or enhanced (patient-oriented) doctor-patient interaction., Design: This trial uses two-way factorial allocation to randomize people with new onset common cold in two directions: pill related and doctor related. In one direction, participants are randomized to (1) no pills, (2) blinded placebo, (3) blinded echinacea, or (4) unblinded open-label echinacea. In the other direction, participants are randomized to: (1) no doctor-patient interaction, (2) standard doctor-patient interaction, and (3) enhanced doctor-patient interaction. Enhanced interaction includes education, empathy, empowerment, positive prognosis, and connectedness. Area under the time severity curve is the primary outcome, with the Wisconsin Upper Respiratory Symptom Survey (WURSS-21) the measure of severity. A priori power studies called for a sample size of N = 720 trial finishers to detect 15% to 20% between-group differences in this outcome. Secondary outcomes include general health-related quality of life, perceived stress, interpersonal support, optimism, patient satisfaction, and positive and negative affectivity. Two biomarkers are also assessed: interleukin-8 (inflammatory cytokine) and neutrophil count from nasal wash., Importance: This paper describes the rationale and methodology of a trial assessing placebo effects related to pills and to doctor-patient interaction. This is one of very few similar studies and is the first in the common cold. Data collected will also provide an excellent opportunity to investigate relationships among demographic (age, sex, education, income) and psychosocial (perceived stress, interpersonal support, optimism, affectivity) indicators in relation to common cold outcomes.

Purpose: We qualitatively assessed attitudes regarding use of hypertonic saline nasal irrigation (HSNI) for frequent rhinosinusitis and chronic sinonasal symptoms in a 3-part, multimethod study., Methods: We conducted semistructured, in-depth interviews with 28 participants who recently used nasal irrigation in studies assessing HSNI., Results: Four themes emerged: (1) HSNI improved self-management of sinus symptoms, creating a sense of empowerment; (2) HSNI produced rapid and long-term improvement in quality of life; (3) participants identified discomfort, time, and mild side effects as barriers to HSNI use; and (4) participants identified aspects of training and at-home use that overcame these barriers., Conclusion: HSNI is a safe, well-tolerated, inexpensive, effective, long-term therapy that patients with chronic sinonasal symptoms can and will use at home with minimal training and follow-up. Success with HSNI will likely be improved by patient education.
