Abstract
ObjectiveAdhesive capsulitis is a common painful shoulder condition. Treatment for the condition remains unsatisfactory. Suprascapular nerve block (SSNB) shows promise as a treatment option for adhesive capsulitis but there are no randomised controlled trials that examine its effect on pain or duration of the condition. The objective of this study was to examine the efficacy of SSNB for the management of adhesive capsulitis.MethodsA randomised double-blind placebo-controlled trial of SSNB and standard therapy versus placebo and standard therapy was performed. In total, 54 patients were enrolled in the study. 27 patients received a glenohumeral joint (GHJ) injection and physiotherapy plus a 3-month SSNB, and 27 patients received a GHJ injection and physiotherapy plus a 3-month placebo injection. Patients were followed to resolution of their symptoms as measured by a combination of range of movement, pain scores, Shoulder Pain and Disability Index (SPADI) scores and perceived recovery scores. The primary outcome measure was time to resolution of symptoms.ResultsParticipants who received the SSNB reduced the duration of their symptoms of adhesive capsulitis by an average of 6 months (mean time to resolution 5.4 (95% CI 4.4 to 6.3) months vs 11.2 (95% CI 9.3 to 13) months) in the placebo group. They also had reduced pain scores, improved range of movement and lower SPADI scores compared with the placebo group across all time points.ConclusionSSNB reduced the duration of adhesive capsulitis and resulted in improved pain and disability experience for patients.Trial registration numberAustralian New Zealand Clinical Trials Registry (ANCTRN 12615001378516).

Real-Life Retention Rates and Reasons for Switching of Biological DMARDs in Rheumatoid Arthritis, Psoriatic Arthritis, and Ankylosing Spondylitis. Front Med (Lausanne) 2021; 8:708168. [PMID: 34646840 PMCID: PMC8502861 DOI: 10.3389/fmed.2021.708168] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2021] [Accepted: 07/29/2021] [Indexed: 11/13/2022] Open
Abstract
Aims: To determine real-life biologic/targeted synthetic disease-modifying anti-rheumatic drug (b/tsDMARD) retention rates in rheumatoid arthritis (RA), psoriatic arthritis (PsA), and ankylosing spondylitis (AS), explore reasons for switching and to compare results to previously published data. Methods: Time-to-event analysis for mean treatment duration (estimated as the Restricted Mean Survival Time), b/tsDMARD failure, and b/tsDMARDs switching was performed for 230 patients (n = 147 RA, 46 PsA, 37 AS) who commenced their first b/tsDMARD between 2008 and 2018. Patients were managed in a dedicated “biologics” clinic in a tertiary hospital; the choice of b/tsDMARD was clinician driven based on medical factors and patient preferences. The effect of covariates on switching risk was analysed by a conditional risk-set Cox proportional-hazards model. Treatment retention data was compared to a historical analysis (2002–2008). Results: The proportions remaining on treatment (retention) were similar, throughout follow-up, for the first, second and third b/tsDMARDs across all patients (p = 0.46). When compared to RA patients, the risk of b/tsDMARD failure was halved in PsA patients [Hazard Ratio (HR) = 0.50], but no different in AS patients (HR = 1.0). The respective restricted mean (95%CI) treatment durations, estimated at 5 years of follow-up, were 3.1 (2.9, 3.4), 4.1 (3.7, 4.6), and 3.3 (2.8, 3.9) years, for RA, PsA, and AS, respectively. Age, gender, disease duration, smoking status and the use of concomitant csDMARDS were not associated with the risk of bDMARD failure. The most common reasons for switching in the first and subsequent years were secondary (n = 62) and primary (n = 35) failure. Comparison with historical data indicated no substantive differences in switching of the first biologic for RA and PsA. Conclusion: Similar retention rates of the second and third compared to the first b/tsDMARD in RA, PsA, and AS support a strategy of differential b/tsDMARDs use informed by patient presentation. Despite greater availability of b/tsDMARDs with differing mechanisms of action, retention rates of the first b/tsDMARD remain similar to previous years.

Shoulder range of movement in the general population: age and gender stratified normative data using a community-based cohort. BMC Musculoskelet Disord 2020; 21:676. [PMID: 33046038 PMCID: PMC7549223 DOI: 10.1186/s12891-020-03665-9] [Citation(s) in RCA: 25] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/12/2020] [Accepted: 09/23/2020] [Indexed: 11/26/2022] Open
Abstract
Background An understanding of the average range of movement of the shoulder that is normally achievable is an important part of treatment for shoulder disorders. The average range of active shoulder flexion, abduction and external rotation was measured in a population cohort aged 20 years and over without shoulder pain and/or stiffness in order to provide normative shoulder range data. Methods Cross-sectional analysis using participants in a community-based longitudinal cohort study. There have been three stages of data collection – Stage 1 (1999–2003), Stage 2 (2004–2006) and Stage 3 (2008–2010). Each stage has consisted a of broad ranging computer assisted telephone interview, a self-complete questionnaire and a clinic assessment. Participants in this study are those who undertook assessments in Stage 2. The main outcome measures were active shoulder range of movement (flexion, abduction and external rotation) measured as part of the clinic assessment using a Plurimeter V inclinometer. Mean values were determined and analyses to examine differences between groups (sex and age) were undertaken using non-parametric tests. Results There were 2404 participants (51.5% male), mean age 45.8 years (SD 17.3, range 20–91). The average range of active right shoulder flexion was 161.5° for males and 158.5° for females, and active right shoulder abduction was 151.5° and 149.7° for males and females respectively. Shoulder range of movement declined with age, with mean right active shoulder flexion decreasing by 43° in males and 40.6° in females and right active shoulder abduction by 39.5° and 36.9° respectively. External rotation range also declined, particularly among females. Conclusion To our knowledge this is the largest community-based study providing normative data for active shoulder range of movement. This information can be used to set realistic goals for both clinical practice and clinical trials.

Abstract
BACKGROUND Shoulder pain is a distressing but under-reported and poorly managed symptom in people with motor neurone disease. OBJECTIVES This study aimed to assess the efficacy of suprascapular nerve block for the management of shoulder pain in patients with motor neurone disease. METHODS A total of 27 patients with motor neurone disease and shoulder pain were offered a suprascapular nerve block. Ten of these patients had bilateral shoulder pain and both were injected, making a total of 37 shoulders. The patients were followed up for a total of 3 months, or until death. Shoulder pain was measured using the pain scale (out of 100) of the shoulder pain and disability index and compared with baseline scores and a placebo control group from an earlier study using the same methodology (ACTRN12619000353190). RESULTS Following the nerve block there was a significant improvement of pain scores from baseline (58.4) at week 1 (20.8, p < 0.000), week 6 (17.6, p < 0.000) and week 12 (30.4, p = 0.001) and a significant improvement compared with the control group across each time interval. CONCLUSION Suprascapular nerve block is a safe, effective therapy for patients with chronic shoulder pain.

Genetic polymorphism of the methotrexate transporter ABCG2, blood pressure and markers of arterial function in patients with rheumatoid arthritis: repeated cross-sectional study. PHARMACOGENOMICS & PERSONALIZED MEDICINE 2018; 11:205-210. [PMID: 30519074 PMCID: PMC6237132 DOI: 10.2147/pgpm.s170557] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Indexed: 11/23/2022]
Abstract
Purpose Methotrexate (MTX) treatment is associated with lower blood pressure (BP) and arterial stiffness in rheumatoid arthritis (RA). We investigated associations between single-nucleotide polymorphism (SNP) of the ATP-binding cassette efflux transporter gene ABCG2 (rs2231142), BP, and arterial stiffness in RA patients treated with MTX. Patients and methods Clinical and 24-hour peripheral and central BP, arterial wave reflection (Augmentation Index, AIx), arterial stiffness (Pulse Wave Velocity, PWV), and intracellular MTX polyglutamate (MTXPGs) concentrations were assessed in 56 RA patients on stable treatment with MTX using a repeated cross-sectional study design with measurements at baseline and after 8 months. Results Majority of the RA patients were homozygotes for the normal allele (CC, n=46) whereas 10 were rs2231142 heterozygotes (AC, n=10). MTXPGs concentrations were non-significantly higher in AC when compared to CC (144.3 vs 116.3 nmol/L packed RBCs, P=0.10). At baseline, the AC group had significantly lower age-adjusted clinical systolic BP (SBP) (P=0.01), 24-hour peripheral SBP (P=0.003), and central SBP (P=0.02) when compared to the CC group. However, AIx and PWV values were not significantly different between the two groups. When data from both visits were combined in a single analysis, and additionally adjusted for visit, gender, body mass index, and Disease Activity Score 28, the trend in SBP differences between-groups persisted but was no longer significant. Conclusion Future studies are required to test the hypothesis that this genetic polymorphism is associated with lower BP, arterial stiffness, and possibly, cardiovascular risk, in RA patients treated with MTX.

Fat mass, but not fat-free mass, predicts increased foot pain with obesity, independent of bariatric surgery. Surg Obes Relat Dis 2018; 14:1389-1395. [PMID: 30057094 DOI: 10.1016/j.soard.2018.06.015] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2018] [Revised: 06/07/2018] [Accepted: 06/14/2018] [Indexed: 01/23/2023]
Abstract
BACKGROUND Foot pain is a common manifestation of obesity. OBJECTIVE To determine if bariatric surgery is associated with a reduction in foot pain and if body mass index (BMI) or body composition predict a change in foot pain. SETTING University hospital. METHODS Participants with foot pain awaiting bariatric surgery were recruited for this prospective study. Multivariable linear regression was used to determine predictors of change in foot pain between baseline and 6-month follow-up using body composition (fat mass index and fat-free mass index) or BMI, adjusting for, depression, age, sex, and group (surgery versus control). RESULTS Forty-five participants (38 female), mean ± standard deviation age of 45.7 ± 9.4 years, were recruited for this study. Twenty-nine participants mean ± standard deviation BMI of 44.8 ± 7.0 kg underwent bariatric surgery, while 16 participants mean ± standard deviation BMI of 47.9 ± 5.2 kg were on the waiting list (control). One participant was lost to follow-up. The treatment group lost a mean of 24.3 kg (95% confidence interval [CI] 21.1-27.5), while the control group gained 1.2 kg (95% CI -2.5 to 4.9), respectively. In multivariable analysis, bariatric surgery was significantly associated with reduced foot pain at 6-month follow-up -32.6 points (95% CI -43.8 to -21.4, P < .001), while fat mass index was significantly associated with increased pain at follow-up 1.5 points (95% CI .2 to 2.8, P = .027), after controlling for fat-free mass index, age, sex, and depression. CONCLUSIONS Bariatric surgery was significantly associated with reduced foot pain. Higher baseline fat mass index, but not fat-free mass index or BMI, was predictive of increased foot pain at follow-up. Foot pain may be mediated by metabolic, rather than mechanical, factors in bariatric surgery candidates.

The association between body fat and musculoskeletal pain: a systematic review and meta-analysis. BMC Musculoskelet Disord 2018; 19:233. [PMID: 30021590 PMCID: PMC6052598 DOI: 10.1186/s12891-018-2137-0] [Citation(s) in RCA: 87] [Impact Index Per Article: 14.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/20/2018] [Accepted: 06/18/2018] [Indexed: 12/31/2022] Open
Abstract
BACKGROUND Obesity and musculoskeletal pain are strongly related, but there is emerging evidence that body fat, not body weight, may be a better indicator of risk. There is, therefore, a need to determine if body fat is associated with musculoskeletal pain as it may improve management strategies. The aim of this systematic review was to investigate the association between body fat and musculoskeletal pain. METHODS Seven electronic databases were searched from inception to 8th January 2018. Cross-sectional and longitudinal studies investigating the association between measures of body fat and musculoskeletal pain were included. All included articles were assessed for methodological rigour using the Epidemiology Appraisal Instrument. Standardised mean differences (SMDs) and effect estimates were pooled for meta-analysis. RESULTS A total of 10,221 citations were identified through the database searching, which after abstract and full-text review, yielded 28 unique articles. Fourteen studies were included in the meta-analyses, which found significant cross-sectional associations between total body fat mass and widespread pain (SMD 0.49, 95% CI 0.37-0.61, p < 0.001). Individuals with low-back pain and knee pain had a higher body fat percentage than asymptomatic controls (SMD 0.34, 95% CI 0.17-0.52, p < 0.001 and SMD 0.18, 95% CI 0.05-0.32, p = 0.009, respectively). Fat mass index was significantly, albeit weakly, associated with foot pain (SMD 0.05, 95% CI 0.03-0.06, p < 0.001). Longitudinal studies (n = 8) were unsuitable for meta-analysis, but were largely indicative of elevated body fat increasing the risk of incident and worsening joint pain. There was conflicting evidence for an association between body fat percentage and incident low-back pain (3 studies, follow-up 4-20 years). Increasing knee pain (1 study) and incident foot pain (2 studies) were positively associated with body fat percentage and fat mass index. The percentage of items in the EAI graded as 'yes' for each study ranged from 23 to 85%, indicating variable methodological quality of the included studies. CONCLUSIONS This systematic review and meta-analysis identified positive cross-sectional associations between increased body fat and widespread and single-site joint pain in the low-back, knee and foot. Longitudinal studies suggest elevated body fat may infer increased risk of incident and worsening joint pain, although further high-quality studies are required.

Changes in foot pain, structure and function following bariatric surgery. J Foot Ankle Res 2018; 11:35.

Abstract
Background Bariatric surgery candidates have a high prevalence of foot pain, depression and elevated plantar pressures. There is, however, limited research into how these factors interact pre- and post-surgery. The aims of this study were therefore to investigate the mechanical and non-mechanical factors associated with foot pain severity before, and the change after, surgery. Methods Bariatric surgery candidates underwent baseline and six-month follow-up measures. Foot pain was measured with the Manchester-Oxford Foot Questionnaire. Mechanical measures included body mass index (BMI), dynamic plantar pressures, radiographic foot posture, and hindfoot range of motion. Depressive symptoms, the non-mechanical measure, were assessed by questionnaire. Multivariable linear regression was used to determine which variables were associated with foot pain at baseline and at follow-up. Multilevel repeated models assessed the associations between foot pain and plantar pressure, adjusting for the interaction between group and follow-up time. Results Forty-five participants (84% female), with mean (SD) age of 45.7 (9.4) years were recruited. Twenty-nine participants had bariatric surgery and 16 participants remained on the waiting list (controls). Following bariatric surgery, foot pain reduced significantly by - 35.7 points (95% CI -42.2 to - 28.8), while depressive symptoms and whole foot peak pressures had a significant mean change of - 5.9 points (95% CI -10.3 to - 1.5) and - 36 kPa (95% CI -50 to - 22), respectively. In multivariable analysis, depressive symptoms were associated with foot pain at baseline β = 0.7 (95% CI 0.2 to 1.2) after controlling for age, gender, BMI, foot posture and plantar pressure. Depressive symptoms were also associated with foot pain at follow-up in those undergoing bariatric surgery, β = 1.2 (95% CI 0.8 to 1.7). Foot posture and hindfoot range of motion did not change following surgery and a change in plantar pressures was not associated with a change in foot pain. Conclusions Foot pain severity in bariatric surgery candidates was associated with depressive symptoms at baseline. Reduced foot pain following bariatric surgery was associated with an improvement in depressive symptoms, without a significant change in foot posture or foot function. Foot pain severity in bariatric candidates may be mediated by non-mechanical or non-local factors before and following surgery.

Methotrexate, blood pressure and markers of arterial function in patients with rheumatoid arthritis: a repeated cross-sectional study. Ther Adv Musculoskelet Dis 2017; 9:213-229. [PMID: 28932292 DOI: 10.1177/1759720x17719850] [Citation(s) in RCA: 26] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2017] [Accepted: 06/15/2017] [Indexed: 12/22/2022] Open
Abstract
BACKGROUND Methotrexate (MTX) treatment in rheumatoid arthritis (RA) has been associated with lower cardiovascular risk compared to other disease-modifying antirheumatic drugs (DMARDs). We sought to identify whether the MTX-associated cardioprotection involves changes in blood pressure (BP) and/or arterial function. METHODS Clinic and 24-hour peripheral and central systolic and diastolic BP (SBP and DBP), augmentation index (AIx), pulse wave velocity (PWV) and plasma asymmetric dimethylarginine (ADMA) were assessed in RA patients on stable treatment with either MTX ± other DMARDs (MTX group, n = 56, age 61 ± 13 years, 70% females) or other DMARDs (non-MTX group, n = 30, age 63 ± 12 years, 76% females). Measurements were performed at baseline and after 8 months. RESULTS After adjusting for visit, age, gender, body mass index, folic acid use and 28-joint disease activity score, the MTX group had significantly lower clinic peripheral SBP (-7.7 mmHg, 95% CI -13.2 to -2.3, p = 0.006) and DBP (-6.1 mmHg, 95% CI -9.8 to -2.4, p = 0.001) and clinic central SBP (-7.8 mmHg, 95% CI -13.1 to -2.6, p = 0.003) and DBP (-5.4 mmHg, 95% CI -9.1 to -1.6, p = 0.005) versus the non-MTX group. Furthermore, the MTX group had significantly lower 24-hour peripheral and central SBP and DBP and PWV versus the non-MTX group (p < 0.01 for all comparisons). By contrast, there were no significant between-group differences in AIx and ADMA. CONCLUSIONS RA patients on MTX treatment had significantly lower clinic and 24-hour peripheral and central BP compared to those who did not take MTX. The lower BP with MTX may be related to differences in PWV, but not in AIx or ADMA concentrations. Further longitudinal studies including randomized controlled trials are warranted to confirm these findings, to identify other possible mechanisms responsible for the effects of MTX on BP and PWV, and to establish whether these effects might account for the reduced cardiovascular risk with MTX.

Abstract
Background There is a well-recognised relationship between body weight, plantar pressures and foot pain, but the temporal association between these factors is unknown. The aim of this study was to investigate the relationships between increasing weight, plantar pressures and foot pain over a two-year period. Methods Fifty-one participants (33 women and 18 men) completed the two-year longitudinal cohort study. The sample had a mean (standard deviation (SD)) age of 52.6 (8.5) years. At baseline and follow-up, participants completed the Manchester Foot Pain and Disability Index questionnaire, and underwent anthropometric measures, including body weight, body mass index, and dynamic plantar pressures. Within-group analyses examined differences in body weight, foot pain and plantar pressures between baseline and follow up, and multivariate regression analysis examined associations between change in body weight, foot pain and plantar pressure. Path analysis assessed the total impact of both the direct and indirect effects of change in body weight on plantar pressure and pain variables. Results Mean (SD) body weight increased from 80.3 (19.3), to 82.3 (20.6) kg, p = 0.016 from baseline to follow up. The change in body weight ranged from −16.1 to 12.7 kg. The heel was the only site to exhibit increased peak plantar pressures between baseline and follow up. After adjustment for age, gender and change in contact time (where appropriate), there were significant associations between: (i) change in body weight and changes in midfoot plantar pressure (B = 4.648, p = 0.038) and functional limitation (B = 0.409, p = 0.010), (ii) plantar pressure change in the heel and both functional limitation (B = 4.054, p = 0.013) and pain intensity (B = 1.831, p = 0.006), (iii) plantar pressure change in the midfoot and both functional limitation (B = 4.505, p = 0.018) and pain intensity (B = 1.913, p = 0.015). Path analysis indicated that the effect of increasing body weight on foot-related functional limitation and foot pain intensity may be mediated by increased plantar pressure in the midfoot. Conclusions These findings suggest that as body weight and plantar pressure increase, foot pain increases, and that the midfoot may be the most vulnerable site for pressure-related pain.

Abstract
Body composition and poor mental health are risk factors for developing foot pain, but the role of different fat deposits and psychological features related to chronic pain are not well understood. The aim of this study was to investigate the association between body composition, psychological health and foot pain. Eighty-eight women participated in this study: 44 with chronic, disabling foot pain (mean age 55.3 SD 7.0 years, BMI 29.5 SD 6.7 kg/m2), and 44 age and BMI matched controls. Disabling foot pain was determined from the functional limitation domain of the Manchester Foot Pain and Disability Index. Body composition was measured using dual X-ray absorptiometry and psychological health (catastrophisation, central sensitisation and depression) was measured using three validated questionnaires. Between-group analyses found that foot pain was not significantly associated with body composition variables, but was significantly associated with all psychological health measures (P < 0.001-0.047). Within-group analyses found that the severity of foot pain was significantly correlated with body composition measures: fat mass (total, android, gynoid, and visceral), fat-mass ratios [visceral/subcutaneous (VAT/SAT), visceral/android], fat-mass index (FMI), and depression. In multivariable analysis, VAT/SAT (β 1.27, 95% CI 0.28-2.27), FMI (β 0.14, 95% CI 0.02-0.25) and depression (β 0.06, 95% CI 0.00-0.12) were independently associated with foot pain severity. Psychological health, not body composition, was associated with prevalent foot pain. For women with foot pain, VAT/SAT, FMI and depression were associated with severity. Further work is needed to determine if a reduction in fat mass reduces the severity of foot pain.

Abstract
OBJECTIVE To study the pharmacokinetics and pharmacogenetics of leflunomide and document its efficacy and safety in the treatment of inflammatory arthritis in a patient with end-stage renal disease (ESRD) who was on peritoneal dialysis. CASE SUMMARY Therapy for a 78-year-old man with ESRD who required peritoneal dialysis was started with leflunomide 10 mg/day for psoriatic arthritis. The dosage was increased to 20 mg/day after 3 months. Monitoring was continued until the patient's unexpected death from myocardial infarction at 8 months. Total and unbound teriflunomide (the active metabolite of leflunomide) concentrations were measured by liquid-chromatography-tandem mass spectrometry. Genotyping for CYP2C19 and ABCG2 polymorphisms, both known to influence teriflunomide pharmacokinetics, was also performed. DISCUSSION Total concentrations of teriflunomide varied between 5.2 and 23.2 mg/L, while unbound concentrations varied between 0.0306 and 0.1468 mg/L. The unbound fraction varied between 0.367% and 0.71%. Teriflunomide was found in the dialysate at a concentration of 0.0981 mg/L. A single CYP2C19 loss of function allele was present, as was wild-type ABCG2. Leflunomide appeared to be therapeutically effective, as evidenced by a reduction in daily prednisolone dosage from 20 mg to 6mg; the Disease Activity Score in 28 joints (DAS28) was 5.46 at enrollment and 4.03 after 7 months. Health Assessment Questionnaire—Disability Index improved from 0.5 to 0.125 at 7 months. Numerous significant adverse events that were considered unrelated to leflunomide occurred. CONCLUSIONS Dose adjustment for leflunomide does not appear to be required in the context of ESRD requiring peritoneal dialysis. We present novel evidence that a small amount of teriflunomide is removed by peritoneal dialysis. This case suggests that leflunomide is safe to use as therapy for inflammatory arthritis despite the presence of ESRD requiring peritoneal dialysis.

The use of self-report questions to examine the prevalence of musculoskeletal problems: a test-retest study. BMC Musculoskelet Disord 2016; 17:100. [PMID: 26911879 PMCID: PMC4766689 DOI: 10.1186/s12891-016-0946-6] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/17/2015] [Accepted: 02/13/2016] [Indexed: 12/22/2022] Open
Abstract
Background Case definition has long been an issue for comparability of results obtained for musculoskeletal pain prevalence, however the test-retest reliability of questions used to determine joint pain prevalence has not been examined. The objective of this study was to determine question reliability and the impact of question wording, ordering and the time between questions on responses. Methods A Computer Assisted Telephone Interviewing (CATI) survey was used to re-administer questions collected as part of a population-based longitudinal cohort study. On two different occasions questions were asked of the same sample of 203 community dwelling respondents (which were initially randomly selected) aged 18 years and over at two time points 14 to 27 days apart (average 15 days). Reliability of the questions was assessed using Cohen’s kappa (κ) and intraclass correlation coefficient (ICC) and whether question wording and period effects existed was assessed using a crossover design. Results The self-reported prevalence of doctor diagnosed arthritis demonstrated excellent reliability (κ = 0.84 and κ = 0.79 for questionnaires 1 and 2 respectively). The reliability of questions relating to musculoskeletal pain and/or stiffness ranged from moderate to excellent for both types of questions, that is, those related to ever having joint pain on most days for at least a month (κ = 0.52 to κ = 0.95) and having pain and/or stiffness on most days for the last month (κ = 0.52 to κ = 0.90). However there was an effect of question wording on the results obtained for hand, foot and back pain and/or stiffness indicating that the area of pain may influence prevalence estimates. Conclusions Joint pain and stiffness questions are reliable and can be used to determine prevalence. However, question wording and pain area may impact on estimates with issues such as pain perception and effect on activities playing a possible role in the recall of musculoskeletal pain.

Australian GP management of osteoarthritis following the release of the RACGP guideline for the non-surgical management of hip and knee osteoarthritis. BMC Res Notes 2015; 8:536. [PMID: 26438323 PMCID: PMC4593191 DOI: 10.1186/s13104-015-1531-z] [Citation(s) in RCA: 39] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2015] [Accepted: 09/28/2015] [Indexed: 01/17/2023] Open
Abstract
BACKGROUND Osteoarthritis (OA) is a highly disabling and costly condition with an escalating prevalence in Australia due to the ageing and increasing obesity of the population. The general practitioner (GP) plays a central role in the management of this condition. The aim of this study was to examine opinions about the management of OA by Australian GPs following the release of the Royal Australian College of General Practitioners Guideline for the non-surgical management of hip and knee OA (RACGP OA CPG), and to compare the results with an earlier survey administered by the National Prescribing Service. METHODS In January 2013, a self-administered questionnaire was sent to 228 GPs to determine their treatment approaches to OA management using a clinical vignette of a patient with OA. This was compared with results from a similar survey undertaken in 2006. RESULTS Seventy-nine GPs returned questionnaires (response rate 35%). GP recommendations for paracetamol, a paracetamol/codeine compound, and oral non-steroidal anti-inflammatory drugs (NSAIDs) were consistent with recommendations in the RACGP OA CPG, and varied little from the previous survey. Notably, there was a marked increase between surveys in GP recommendations for tramadol (p = 0.004) and more potent opioids (p < 0.001). Advice about the adverse effects of NSAIDs and codeine and how to manage them increased between surveys (p = 0.038 and 0.005, respectively). For all non-pharmacological treatments, there were only minor changes in the percentage of GP recommendations when compared with the previous survey, however they remain underutilised. CONCLUSIONS GPs generally demonstrated a conservative approach to the treatment of OA, however, the increased recommendations for more potent opioids warrants further investigation. Patients should be made aware of the risks of medications through the use of decision aids, which can provide structured guidance to treatment. Non-pharmacological interventions were not given the importance that is suggested by clinical practice guidelines.

Association of Fat Mass and Adipokines With Foot Pain in a Community Cohort. Arthritis Care Res (Hoboken) 2015; 68:526-33. [PMID: 26315271 DOI: 10.1002/acr.22719] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2015] [Revised: 08/03/2015] [Accepted: 08/18/2015] [Indexed: 12/18/2022]
Abstract
OBJECTIVE To determine, first, if fat mass index (FMI) or fat-free mass index (FFMI) and serum adipokines tumor necrosis factor (TNF) and interleukin-6 (IL-6) are associated with prevalent (stage 2) foot pain, and, second, if they are predictive of future (stage 3) foot pain. METHODS A subset of participants ages ≥50 years (n = 1,462) from the North West Adelaide Health Study were used for this study. Participants from this community cohort were asked in stage 2 (2004-2006) and stage 3 (2008-2010) if they had foot pain, aching, or stiffness. In stage 2, serum adipokines and anthropometry were measured, while body composition was analyzed with dual x-ray absorptiometry. These variables, along with comorbidities and social history, were used in logistic regression analyses to determine if FMI, FFMI, and serum adipokines were associated with foot pain. RESULTS Prevalent foot pain was present in 20.2% of participants, and future foot pain in 36.4%. Following multivariate modeling, the odds of having pain at stage 2 increased by 8% for each FMI unit (odds ratio [OR] 1.08, 95% confidence interval [95% CI] 1.04-1.12), while the odds of having pain at stage 3 increased by 6% for each FMI unit at stage 2 (OR 1.06, 95% CI 1.02-1.11). TNF level, IL-6 level, and FFMI were not associated with pain. CONCLUSION Increased FMI, but not body mass index, FFMI, or TNF or IL-6 level, was associated with both prevalent and future foot pain. These results suggest that body fat may be more important than body weight with respect to foot pain. The role played by other adipokines requires further investigation.

Afferent inhibition and cortical silent periods in shoulder primary motor cortex and effect of a suprascapular nerve block in people experiencing chronic shoulder pain. Clin Neurophysiol 2015; 127:769-778. [PMID: 25900020 DOI: 10.1016/j.clinph.2015.03.012] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2014] [Revised: 03/16/2015] [Accepted: 03/23/2015] [Indexed: 10/23/2022]
Abstract
OBJECTIVE To characterise short afferent inhibition (SAI) and the cortical silent period (CSP) in the primary motor cortex representations of the infraspinatus muscle in healthy adults and people experiencing chronic shoulder pain, to determine the impact of a suprascapular nerve block (SSNB). METHODS Neurophysiological measures were obtained in 18 controls and 8 patients with chronic shoulder pain, pre and post SSNB and 1 week later. Pain intensity was assessed by a visual analogue scale. RESULTS SAI was apparent in controls (all P<0.03) and a CSP was observed which reduced in the presence of SAI (all P<0.0001). Compared to controls, shoulder pain patients demonstrated higher active motor threshold (P=0.046), less SAI (P=0.044), a longer CSP (P=0.048) and less modulation of the CSP by SAI (P=0.045). Higher motor thresholds were related to higher pain scores (P=0.009). The SSNB immediately restored SAI (P=0.013), with a positive relationship between increased SAI and reduced pain (P=0.031). The SSNB further reduced modulation of CSP by SAI at 1 week post injection (P=0.006). CONCLUSIONS SAI and the CSP were present and demonstrated robust interaction in controls, which was aberrant in patients. The SSNB transiently restored SAI but had no effect on the CSP; however CSP modulation by SAI was further attenuated 1 week post injection. SIGNIFICANCE The current findings improve understanding of the neurophysiology of the shoulder motor cortex and its modulation by chronic pain. The effect of SSNB in shoulder pain patients should be interpreted with caution until proven in a larger population. Interventions that target intracortical inhibition might increase efficacy in people with chronic shoulder pain.

Abstract
Background Rheumatoid arthritis (RA) is known to increase the risk of cardiovascular (CV) disease. However, the individual impact of traditional CV risk factors in RA is unknown. Objective To assess the strength of the association between individual CV risk factors and rate of either myocardial infarction (MI), combined CV morbidity (MI, angina pectoris, heart failure, stroke, and peripheral arterial disease (PAD)) or CV mortality in RA patients. Methods RA studies reporting traditional CV risk factors [hypertension, type 2 diabetes (T2D), smoking, hypercholesterolaemia, obesity, and physical inactivity] as exposures and MI, CV morbidity (MI, angina, heart failure, stroke, and PAD combined) or CV mortality alone as outcomes were searched until March 2013 using MEDLINE, Scopus and Cochrane. Meta-analyses combined relative risk (RR) estimates from each study where either the RR and 95% confidence intervals or where raw counts were available. Results Ten studies reporting sufficient data for inclusion into meta-analyses were identified. Relevant data was available for each risk factor and MI and CV morbidity but no studies reported on CV mortality. Risk of MI increased in RA patients with hypertension (RR 1.84, 95% CI 1.38, 2.46) and T2D (RR 1.89, 95% CI 1.36, 2.63). CV morbidity increased with hypertension (RR 2.24, 95% CI 1.42, 3.06), T2D (RR 1.94, 95% CI 1.58, 2.30), smoking (RR 1.50, 95% CI 1.15, 1.84), hypercholesterolaemia (RR 1.73, 95% CI 1.03, 2.44) and obesity (RR 1.16, 95% CI 1.03, 1.29) but not with physical inactivity (RR 1.00, 95% CI 0.71, 1.29). Conclusion Hypertension, T2D, smoking, hypercholesterolaemia and obesity increased CV risk in patients with RA. These results highlight the importance of managing CV risk factors in RA, similarly to non-RA patients.

Abstract
AIM The aim of this study was to determine the prevalence of structural shoulder pathology using magnetic resonance imaging (MRI) in three groups of older people: those with current shoulder pain, those with a previous history of shoulder pain and those with no history of shoulder pain, within a community-based sample. METHODS Thirty subjects (10 within each of the three groups) participated in the study. Subjects were recruited by telephone and underwent a clinical examination of shoulder and neck range of movement (to ensure pain was not referred from the neck). Subjects completed the Shoulder Pain and Disability Index (SPADI) and underwent MRI and X-ray of the relevant shoulder. The X-rays and MRI were read independently by two experienced musculoskeletal radiologists blinded to each participant's symptoms. The MRIs were read using a structured reporting system. RESULTS The mean range of shoulder movement on both the right and left sides was lower for the current pain group compared to both the no and previous pain groups. On X-ray, there was no significant difference between groups in terms of glenohumeral and/or acromioclavicular degenerative changes. Tendinosis and tears of the rotator cuff were present in the majority of participants in each group. Labral abnormalities were rare among all groups. CONCLUSION Shoulder pathology is apparent in both symptomatic and asymptomatic shoulders and clinical symptoms may not match radiological findings. The cost burden of ordering MRI scans is significant and the relevance of the findings are questionable when investigating shoulder pain.

Abstract
BACKGROUND Levels of vitamin D in the population have come under increasing scrutiny, however there are only a few studies in Australia which measure levels in the general population. The aim of this study was to measure the levels of vitamin D within a large population cohort and examine the association with seasons and selected demographic and health risk factors. METHODS A longitudinal cohort study of 2413 participants in the northwest suburbs of Adelaide, South Australia conducted between 2008 and 2010 was used to examine serum levels of 25-hydroxy vitamin D (25(OH)D) in relation to demographic characteristics (age, sex, income, education and country of birth), seasons, the use of vitamin D supplements and selected health risk factors (physical activity, body mass index and smoking). Both unadjusted and adjusted mean levels of serum 25(OH)D were examined, as were the factors associated with the unadjusted and adjusted prevalence of serum 25(OH)D levels below 50 and 75 nmol/L. RESULTS Overall, the mean level of serum 25(OH)D was 69.2 nmol/L with 22.7% of the population having a serum 25(OH)D level below 50 nmol/L, the level which is generally recognised as vitamin D deficiency. There were significantly higher levels of 25(OH)D among males compared to females (t = 4.65, p < 0.001). Higher levels of 25(OH)D were also measured in summer and autumn compared with winter and spring. Generally, mean levels of 25(OH)D were lower in those classified as obese. Smokers and those undertaking no or less than 150 minutes/week of physical activity also had lower levels of serum vitamin D. Obesity (as classified by body mass index), season and undertaking an insufficient level of physical activity to obtain a health benefit were significantly associated with the prevalence of vitamin D deficiency. CONCLUSIONS Vitamin D deficiency is prevalent in South Australia, affecting almost one quarter of the population and levels are related to activity, obesity and season even when adjusted for confounding factors. Improved methods of addressing vitamin D levels in population are required.

Abstract
Background and Purpose—
Shoulder pain is a common complication after stroke that can impede participation in rehabilitation and has been associated with poorer outcomes. Evidence-based treatments for hemiplegic shoulder pain are limited. Suprascapular nerve block (SSNB) is a safe and effective treatment of shoulder pain associated with arthritic shoulder conditions, but its usefulness in a stroke population is unclear.
Methods—
We undertook a randomized controlled trial assessing the effectiveness of SSNB in a population of 64 stroke patients (onset < 1 year) with hemiplegic shoulder pain. The primary outcome was pain measured on a visual analogue scale (VAS). Secondary outcomes were disability (Modified Rankin Scale, Croft Disability Index) and quality of life (EuroQol Health Questionnaire). All participants were assessed before randomization, and at 1, 4, and 12 weeks postintervention. Both groups continued with routine therapy.
Results—
Although both intervention and control groups demonstrated reduction in pain score, participants who received SSNB consistently demonstrated superior, statistically significant pain reduction compared with placebo. Mean VAS reduction in the SSNB group was >18 mm greater than participants receiving placebo injection. The number needed to treat with SSNB to reduce 1 stroke survivor’s pain by 50% at 4 weeks is 4. No significant differences in function or quality of life were observed. No adverse events were reported.
Conclusions—
Suprascapular nerve block is a safe and effective treatment for patients with hemiplegic shoulder pain.

General practitioner management of shoulder pain in comparison with rheumatologist expectation of care and best evidence: an Australian national survey. PLoS One 2013; 8:e61243.

Abstract
OBJECTIVES To determine whether current care for common shoulder problems in Australian general practice is in keeping with rheumatologist expectations and the best available evidence. METHODS We performed a mailed survey of a random sample of 3500 Australian GPs and an online survey of all 270 rheumatologists in Australia in June 2009. Each survey included four vignettes (first presentation of shoulder pain due to rotator cuff tendinopathy, acute rotator cuff tear in a 45 year-old labourer and early and later presentation of adhesive capsulitis). For each vignette, GPs were asked to indicate their management, rheumatologists were asked to indicate appropriate primary care, and we determined best available evidence from relevant Cochrane and other systematic reviews and published guidelines. RESULTS Data were available for at least one vignette for 614/3500 (17.5%) GPs and 64 (23.8%) rheumatologists. For first presentation of rotator cuff tendinopathy, 69% and 82% of GPs and 50% and 56% rheumatologists would order a shoulder X-ray and ultrasound respectively (between group comparisons P = 0.004 and P<0001). Only 66% GPs and 60% rheumatologists would refer to an orthopaedic surgeon for the acute rotator cuff tear. For adhesive capsulitis, significantly more rheumatologists recommended treatments of known benefit (e.g. glucocorticoid injection (56% versus 14%, P<0.0001), short course of oral glucocorticoids (36% versus 6%, p<0.0001) and arthrographic distension of the glenohumeral joint (41% versus 19%, P<0.0001). CONCLUSIONS There is a mismatch between the stated management of common shoulder problems encountered in primary care by GPs, rheumatologist expectations of GP care and the available evidence.

Abstract
Background Shoulder pain is a common complication of a stroke which can impede participation in rehabilitation programs and has been associated with poorer outcomes. The evidence base for current medical and therapeutic management options of hemiplegic shoulder pain is limited. This study will evaluate the use of suprascapular nerve block injection as part of an interdisciplinary approach to the treatment of shoulder pain following stroke. The technique has previously been proven safe and effective in the treatment of shoulder pain associated with rheumatoid arthritis and degenerative shoulder conditions but its usefulness in a stroke population is unclear. Methods/Design A double blind randomised placebo controlled trial will assess the effect of a suprascapular nerve block compared with placebo in a population of 66 stroke patients. The trial will measure effect of injection on the primary outcome of pain, and secondary outcomes of function and quality of life. Measurements will take place at baseline, and 1, 4 and 12 weeks post intervention. Both groups will continue to receive routine physiotherapy and standard ward care. Discussion The results of this study could reduce pain symptoms in persons with mechanical shoulder pain post stroke and provide improvement in upper limb function.

Abstract
BACKGROUND For a number of reasons, engaging the interest of medical students in the discipline of occupational and environmental medicine (OEM) can be challenging. AIMS To renew a curriculum in OEM within a graduate medical programme with an emphasis on student involvement to maximize their interest in the topic. METHODS A second year student cohort of a 4 year graduate medical programme was surveyed as to their preferences for the content of a short course of OEM embedded in their medical course. The course was extensively rewritten as a result of the student survey, with a number of topics deleted from the old course and new topics added. In order to validate the content of the new course, local occupational physicians (OPs) were also surveyed as to their opinion of an appropriate curriculum in OEM for medical students. The new course was taught to the subsequent cohort of second year medical students. The students' ratings of the course pre- and post-revision were compared. RESULTS The student satisfaction rates of the course significantly improved as a result of the changes. The content of the student-led curriculum was strikingly similar to the course proposed by the local OP with a few key exceptions. CONCLUSIONS Student involvement in curriculum design in OEM is entirely feasible. It can result in a curriculum similar to that designed by expert opinion but has the advantage of strongly engaging student interest.

Abstract
BACKGROUND Shoulder pain is a common problem that can impact on work. Leisure time physical activity (LTPA) has the potential to reduce the impact of shoulder pain through its physiological, psychological and social benefits. AIMS To determine whether LTPA reduces the prevalence of shoulder pain in a working population. METHODS Participants were selected from a longitudinal population-based cohort study, the North West Adelaide Health Study. Information was gathered by questionnaire on LTPA, smoking, depression and socio-economic factors. Body mass index was measured in a clinic setting. Occupational physical activity (OPA) estimated by job title and shoulder pain was measured using the Shoulder Pain and Disability Index. Workers with and without shoulder pain were compared using logistic regression analysis. RESULTS Of the 1502 working participants, 16% reported having current shoulder pain. Shoulder pain was associated with older age (OR 1.98, 95% CI: 1.31-2.99) (age >50 years), smoking (OR 1.44, CI: 1.02-2.04), secondary-level educational attainment (OR 1.68, 95% CI: 1.07-2.65), high body mass index (BMI) (OR 1.54, 95% CI: 1.14-2.08) and depression (OR 2.42, 95% CI: 1.60-3.64). There was no effect of LTPA on shoulder pain. CONCLUSIONS In this community-based cohort, there was no statistically significant association seen between LTPA, OPA and shoulder pain. There was, however, an association between smoking, BMI, secondary-level education, depression and shoulder pain. These modifiable factors may be better targets for preventive efforts than LTPA to reduce the risk of shoulder pain.

Abstract
OBJECTIVES To assess the association of shoulder pain and/or stiffness and diabetes mellitus in a population based cohort. METHODS Participants were randomly recruited from the North West Adelaide Health Study, a longitudinal, population based study. In the second stage, 3128 participants were assessed for diabetes mellitus and shoulder complaints via questionnaires, the Shoulder Pain and Disability Index (SPADI), physical assessment, blood sampling for fasting plasma glucose, and HbA1c levels. RESULTS Overall, 682 (21.8%) participants experienced shoulder pain and/or stiffness and 221 participants (7.1%) fulfilled criteria for diabetes mellitus. Those with diabetes had a higher prevalence of shoulder pain and/or stiffness (27.9% vs 21.3%; p = 0.025), and poorer SPADI disability subscore (p = 0.01) and total SPADI score (p = 0.02). After controlling for age, sex, obesity, and current smoking, the prevalence of shoulder pain and/or stiffness did not differ significantly between those with diabetes and those without (OR 1.05, 95% CI 0.76-1.45), nor were there significant differences in the SPADI disability subscore (p = 0.39) or total SPADI score (p = 0.32) between the 2 groups. After adjustment for covariates, there was no association between higher levels of HbA1c and shoulder pain and/or stiffness (p > 0.8). Range of shoulder movement was significantly reduced in those with diabetes (p < 0.05). CONCLUSIONS There is a higher prevalence of shoulder pain and/or stiffness in people with diabetes mellitus. The differences observed between those with diabetes and those without can largely be explained by the confounding factors of age, sex, obesity, and current smoking.

Abstract
BACKGROUND In Australia medical practitioners are often required to assume the responsibility for assessing fitness to drive. However the clinical practice, knowledge and attitudes of doctors with regards to this responsibility are unknown. The aim of this study was to determine the clinical practice, knowledge and attitudes of public hospital doctors in the area of fitness-to-drive decision-making. METHODS A survey of public hospital doctors in Adelaide, South Australia was undertaken in 2003, shortly after the promulgation nationwide of guidelines to assist in the assessment of patients' fitness to drive. The survey sought details on medical practitioners' clinical practice in this regard, as well as their knowledge of the guidelines. In addition, it sought their attitudes to undertake this responsibility. RESULTS Eighty-four per cent of respondents had at some time in their working career at least discussed the issue of fitness to drive with their patients. Seventy per cent acknowledged that they had received the recently published guidelines on fitness to drive. Despite this, knowledge of the contents of the guidelines was poor. Attitudes to the responsibility were equivocal with several significant reservations expressed. CONCLUSION Public hospital doctors in Australia have poor knowledge of the content of published guidelines in the area of fitness to drive. If this situation is to be improved, alternative approaches to the education of this group with respect to this significant public health problem should be considered. Many doctors are uncomfortable with their responsibilities in this area and alternative models of decision-making should be considered.

Abstract
BACKGROUND The aim of the study was to determine the prevalence of work disability in a cohort of Australians with rheumatoid arthritis. METHODS A cross-sectional study of a sample of 497 individuals aged 18-65 years with rheumatoid arthritis in Adelaide, South Australia, was carried out. RESULTS Of those employed, 130 (51%) were in full-time employment (> or= 35 h per week) work and 124 (49%) were in part-time employment (average 20 h per week). Overall, the observed/expected numbers working were 254/316 (relative risk 0.8 (0.69-0.91)). Using a comparator adjusted by removing those on the disability support pension, the relative risk of the working was 0.74. The observed/expected numbers working part time in the study group were 124/89 (relative risk 1.4 (1.25-1.65)). Those who continued to work had lower Health Assessment Questionnaire scores, less morning stiffness, superior scores for patient assessed level of function, lower pain scores, lower joint counts, a lower C-reactive protein, better measures of 'patient global assessment' and higher levels of education compared with the group who had ceased work. Overall, of those working at the time of diagnosis, 20% had ceased work within 5 years and approximately 40% had ceased work by 20 years. Of those who ceased work, the mean duration from time of diagnosis to work cessation was 7 years with half the subjects who ceased work doing so within 4 years of diagnosis. CONCLUSION Work disability associated with rheumatoid arthritis in Australia is very significant and costly. Work disability occurs relatively early in the disease and is associated with several identifiable variables, many of which may be amenable to intervention strategies.

Work related upper limb disorders. AUSTRALIAN FAMILY PHYSICIAN 2006; 35:946-50. [PMID: 17149466] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Indexed: 05/12/2023]
Abstract
BACKGROUND Work related upper limb disorders (WRULDs) are among the most common workers' compensation claims. Their management is a challenge for medical practitioners for a range of reasons. OBJECTIVE This article describes the common WRULDs and summarises current management strategies. DISCUSSION The identification and management of WRULDs is complicated by diagnostic, aetiological and therapeutic uncertainties. The workers' compensation system further complicates the issue. Despite this, there are useful strategies that medical practitioners can employ to assist patients with upper limb pain in the work environment to alleviate distress, minimise disability and maximise function.

Abstract
BACKGROUND Suprascapular nerve block is a safe and effective treatment for chronic shoulder pain in arthritis, which can be performed either by direct imaging (CT guided) or in the clinic using anatomical landmarks to determine needle placement. OBJECTIVE To compare a CT guided versus an anatomical landmark approach in a randomised, single blind trial examining the efficacy of suprascapular nerve block for shoulder pain in patients with degenerative joint/rotator cuff disease. METHODS 67 patients with chronic shoulder pain from degenerative disease participated in the trial. 77 shoulders were randomised. The group randomised to receive the block through the anatomical landmark approach received a single suprascapular nerve block. Those in the CT guided group received an injection of methylprednisolone acetate and a smaller volume of bupivacaine around the suprascapular nerve. The patients were followed up for 12 weeks by a "blinded" observer and reviewed at weeks 1, 4, and 12 after the injection. RESULTS Significant improvements were seen in all pain scores and disability in the shoulders receiving both types of nerve block, with no significant differences in the improvement in pain and disability between the two approaches at any time. Improvements in pain and disability scores were clinically and statistically significant. No significant adverse effects occurred in either group. Patient satisfaction scores for pain relief using either approach were high. CONCLUSION The CT guided control and landmark approaches to performing suprascapular nerve blocks result in similar significant and prolonged pain and disability reductions; both approaches are safe.

Abstract
BACKGROUND Shoulder pain from inflammatory arthritis and/or degenerative disease is a common cause of morbidity in the community. It is difficult to treat and there are limited data on the efficacy of most interventions. Suprascapular nerve block has shown promise in limited trials in reducing shoulder pain. There have been no large randomised placebo controlled trials examining the efficacy of suprascapular nerve block for shoulder pain in arthritis and/or degenerative disease using pain and disability end points. OBJECTIVE To perform a randomised, double blind, placebo controlled trial of the efficacy of suprascapular nerve block for shoulder pain in rheumatoid arthritis (RA) and/or degenerative disease of the shoulder. METHODS 83 people with chronic shoulder pain from degenerative disease or RA took part in the trial. If a person had two painful shoulders, these were randomised separately. A total of 108 shoulders were randomised. Patients in the group receiving active treatment had a single suprascapular nerve block following the protocol described by Dangoisse et al, while those in the other group received a placebo injection of normal saline administered subcutaneously. The patients were followed up for 12 weeks by an observer who was unaware of the randomisation and reviewed at weeks 1, 4, and 12 after the injection. Pain, disability, and range of movement data were gathered. RESULTS Clinically and statistically significant improvements in all pain scores, all disability scores, and some range of movement scores in the shoulders receiving suprascapular nerve block compared with those receiving placebo were seen at weeks 1, 4, and 12. There were no significant adverse effects in either group. CONCLUSION Suprascapular nerve block is a safe and efficacious treatment for the treatment of shoulder pain in degenerative disease and/or arthritis. It improves pain, disability, and range of movement at the shoulder compared with placebo. It is a useful adjunct treatment for the practising clinician to assist in the management of a difficult and common clinical problem.

Abstract
OBJECTIVE To undertake a systematic review of randomized placebo-controlled trials to assess and rank the efficacy of pharmacological interventions in preventing radiological progression of rheumatoid arthritis. METHODS The two outcome measures were the weighted standardized mean difference and the odds of progression of X-ray scores pooled as close to 12 months as possible to minimize heterogeneity. RESULTS A total of 38 trials were identified. Of these, 13 were excluded, leaving data on 3907 subjects. Infliximab, cyclosporin, sulphasalazine, leflunomide, methotrexate, parenteral gold, corticosteroids, auranofin and interleukin 1 receptor antagonist were statistically better than placebo in terms of change in erosion scores. All agents were equivalent statistically, with the exception of infliximab (which was superior to the last five agents). There were similar findings for the odds of progression, with the exception of auranofin (P=0.06) and the infliximab-methotrexate comparison (P=0.07). Other agents did not reach statistical significance in either outcome measure. With the exception of the antimalarials, the magnitude of the effect was consistent with the effect seen in short-term disease activity trials. CONCLUSION There is published evidence which supports the efficacy of nine agents in decreasing radiological progression in rheumatoid arthritis.

Abstract
OBJECTIVE To assess student evaluation, satisfaction, and examination outcomes for a new method of teaching musculoskeletal (MSK) medicine clinical skills, structured clinical instruction modules (SCIM), and to compare with the outcomes of a traditional method of teaching clinical skills (small group bedside tutorials). METHODS Year 2 students in a 4 year graduate medical school were taught using the method of bedside senior registrar teaching, supplemented by outpatient attendances in 1997 and by SCIM in 2000. All students in 1997 and 2000 were debriefed at the end of each unit of clinical skills teaching for student feedback on their teaching experience using a standardized questionnaire. At the end of the academic year, all students underwent an objective structured clinical examination (OSCE) in clinical skills that included rheumatology (hand examination) and orthopedic surgery (knee examination) stations. The effect of the method of teaching on the students' performance in the rheumatology (hand) and orthopedic surgery (knee) stations was analyzed. RESULTS Sixty-seven students were taught clinical skills and completed the OSCE in 1997 and 78 students were taught clinical skills by SCIM and completed the OSCE in 2000. The teaching of orthopedics using traditional methods was poor, but there was no difference in satisfaction between traditional methods of teaching and SCIM for orthopedic surgery and rheumatology. There was no statistically significant difference in the performance of students in the hand OSCE stations in 2000 compared to the same station in 1997. There was a small but statistically significant difference in the performance of students in 1997 and 2000 in the knee station, the 1997 students performing better in this station. CONCLUSION The SCIM is an effective method of teaching clinical skills in MSK medicine, comparable with patient partners and traditional registrar based bedside teaching methods, but it is less resource intensive.

Abstract
OBJECTIVE To evaluate student preferences and examination outcomes of 2 different methods of teaching musculoskeletal (MSK) medicine examination techniques. METHODS Year 2 students in a 4 year graduate medical school were randomized to 3 teaching groups: students in Group 1 were taught by rheumatology fellows, Group 2 by patient partners, while group 3 were randomly allocated to either patient partner (3A) or rheumatology trainee (3B) teaching. All students were debriefed at the end of each teaching block of 4 weeks for feedback on their teaching experience using a standardized questionnaire. In addition, at the end of the academic year, all students sat an objective structured clinical examination (OSCE) in clinical skills that contained a rheumatology station. The effect of method of teaching on students' performance in the rheumatology station was analyzed. RESULTS Eighty medical students participated in the study. Overall, there was no difference in student ratings of either mode of teaching, although the students reported that patient partner teaching gave more opportunity to practice MSK examination skills and also provided greater feedback to the student. Students reported a preference for rheumatology trainee teaching because they believed the teaching would be more relevant to the content of the examination. There was no statistically significant difference in the performance of the students in the OSCE rheumatology station in regard to the mode of teaching they had received prior to the examination. CONCLUSION Patient partner teaching is as effective a method of teaching clinical skills in MSK medicine as a traditional resident based form of teaching, with student benefits from patient feedback and greater "hands-on" opportunities. The assessment process should incorporate patient partners to assess the unique aspects of patient educator based teaching of MSK examination techniques.

Abstract
All the medical schools in Australia and New Zealand were surveyed in order to determine the amount of teaching devoted to occupational and environmental medicine in the medical courses in 1998. A 100% response rate was achieved. The results showed that the number of hours devoted to these topics varied widely, but averaged 12.8 h and 10.5 topics. The most significant factor accounting for the variability was the presence on the universities' teaching staff of individuals trained in the practice of occupational medicine. While our findings show a greater time devoted to these topics than those of similar studies in the United States and Britain, the absolute time remains small when compared with the prevalence of occupational medicine problems in the community. There is little congruence in terms of both content and assessment processes between schools.

Abstract
CD59 is a complement regulatory protein and may also act as a signal-transducing molecule. CD59 transgenic mice have been generated using a CD59 minigene (CD59 minigene-1). Although this minigene contained a 4.6-kilobase pair 5'-flanking region from the human CD59 gene as a promoter, the expression levels of the CD59 mRNA were substantially lower than those observed in humans, suggesting that CD59 gene expression might also require other transcriptional regulatory elements such as an enhancer. To investigate the transcriptional regulation of the CD59 gene, we used three cell lines that express CD59 at different levels. We have identified DNase I-hypersensitive sites in intron 1 in HeLa cells, which express CD59 at high levels, but not in Jurkat (intermediate level) or Raji cells (low level). Furthermore, cell line-specific enhancer activity was detected in a fragment containing these DNase I-hypersensitive sites. The CD59 enhancer was mapped to between -1155 and -888 upstream of the 5'-end of exon 2. To investigate the enhancer activity in vivo, a new CD59 minigene was constructed by the addition of the enhancer fragment into CD59 minigene-1. High expressor CD59 transgenic mice were generated using the new minigene.
