Correlations among enthesitis, clinical, radiographic and quality of life parameters in patients with ankylosing spondylitis.

Abstract Objectives. To investigate the relationship between enthesitis and disease activity, functional status, fatigue, joint mobility, radiological damage, laboratory parameter and quality of life in patients with ankylosing spondylitis (AS). Methods. A total of 421 patients with AS (323 male and 98 female) who were included in the Turkish League Against Rheumatism Registry were enrolled in the study. The Bath AS Disease Activity Index (BASDAI), fatigue, the Bath AS Functional Index (BASFI), the Bath AS Metrology Index (BASMI), the Maastricht AS Enthesitis Score (MASES), AS quality of life (ASQoL), the Bath AS Radiology Index (BASRI) and erythrocyte sedimentation rate (ESR) were evaluated. Results. Enthesitis was detected in 27.3% of patients. There were positive correlations between MASES and BASDAI, BASFI and fatigue (p < 0.05). MASES was not correlated with BASRI, BASMI, ASQoL and ESR. The mean MASES score was 1.1 ± 2.4. The most frequent regions of enthesopathies were right iliac crest, spinous process of L5 and proximal to the insertion of left achilles tendon, respectively. Conclusions. Enthesitis was found to be associated with higher disease activity, higher fatigue, worse functional status and lower disease duration. As enthesitis was correlated with BASDAI, we conclude that enthesitis can reflect the disease activity in patients with AS.

Effects of deep heating provided by therapeutic ultrasound on demyelinating nerves.

[Purpose] Physiotherapeutic heating agents are classified into two groups: superficial-heating agents and deep-heating agents. Therapeutic ultrasound is a deep-heating agent used to treat various musculosketal disorders. Numerous studies have attempted to determine the impact of ultrasound on healthy nerve conduction parameters. However, the instantaneous effects of deep heating via ultrasound on demyelinating nerves do not appear to have been described previously. The present study aimed to assess and compare the impact of ultrasound on demyelinating nerve and healthy nerve conduction parameters. [Subjects and Methods] Carpal tunnel syndrome was used as a focal demyelination model. Thirty-two hands of 25 participants with carpal tunnel syndrome were enrolled in the study. Ultrasound parameters were 3.3 MHz, 1.0 W/cm2, 8 minutes, and continuous wave. Electrodiagnostic studies were performed initially, at the midpoint (4th min), and immediately after (8th min) ultrasound application. [Results] Reduced motor conduction velocity was found in demyelinating nerves at the 4th and 8th minutes. Ulnar nerve onset latency was significantly prolonged in the 8th minute recording, compared to the initial value. There were no significant differences in relative velocity and latency changes between demyelinating and normal nerves. [Conclusion] Deep heating via ultrasound may inversely affect conduction velocity in demyelinating nerves.

Agreement of Turkish Physiatrists with the Assessment in Spondyloarthritis International Society and the European League Against Rheumatism Recommendations for the Management of Ankylosing Spondylitis and Rheumatoid Arthritis

Background: New developments in the field of targeted therapies or biologic agents led more effective management of ankylosing spondylitis (AS) and rheumatoid arthritis (RA). Recommendations for the management of rheumatic diseases propose to reduce inappropriate use of medications, minimize variations among countries, and enable cost-effective use of health care resources. Objective: The aim this study was to evaluate conceptual agreement of ASsessment in SpondyloArthritis International Society (ASAS) and the EUropean League Against Rheumatism (EULAR) recommendations for the management of AS and EULAR recommendations for RA and to assess the rate of application among Turkish physiatrists in daily clinical practice. Methods: An online survey link has been sent to 1756 Turkish physiatrists with e-mails asking to rate agreement on 11-item ASAS/EULAR AS recommendations and 15-item EULAR RA recommendations with synthetic and biological disease-modifying anti-rheumatic drugs. Also barriers and difficulties for using biologic agents were assessed. Results: Three hundred nine physiatrists (17.5%) completed the survey. The conceptual agreement with both recommendations was very high (Level of agreement; mean 8.35±0.82 and 8.90± 0.67 for RA and AS recommendations, respectively), and the self-declared application of overall recommendations in the clinical practice was also high for both RA and AS (72.42% and 75.71%, respectively). Conclusion: Turkish physiatrists are in good conceptual agreement with the evidence-based recommendations for the management of AS and RA. These efforts may serve to disseminate the knowledge and increase the current awareness among physicians who serve to these patients and also implementation of these recommendations is expected to increase as well.

The relation between joint erosion and forearm bone mineral density in female patients with Rheumatoid Arthritis

Gülnur Taşçı Bozbaş Yazışma Adresi: Physical Medicine and Rehabilitation Department, Adnan Menderes University Medical School, Aydın. e-mail: gulnurtb@yahoo.com Abstract Purpose: Rheumatoid arthritis (RA) is a disease that characterized by joint damage including periarticular osteoporosis and focal bone erosion. Despite the fact that periarticular osteoporosis and erosions are known as radiographic hallmarks of RA, there is a lack of data on the relationship between forearm bone loss and radiographic damage. For this reason, we aimed in this study to determine whether there is a relationship between focal erosions and OP in RA patients. Materials and methods: We evaluated 49 female patients with RA. Anteroposterior hand and foot radiographs and bone mineral density measurement of forearm, hip and lumbar spine with dual x-ray absorptiometry of all patients were taken at simultaneously. Radiographs were analyzed using the Larsen method. Disease activity was evaluated by DAS-28 and functional ability was measured with Health Assessment Questionnaire and Duruöz Hand Index. Results:Patients had the mean age 53.9±11.8 and an average disease duration of 7.9±5.9 years. The erosion score was correlated with bone mineral density of forearm, but not with lumbar spine and hip. The disease activity and functional ability were not correlated with Larsen score. Both osteoporosis in all evaluated area and correlations were not affected by the menopause status and disease duration. Conclusion: Our results demonstrated that bone mineral density of forearm indicate the erosion severity in female patients with RA.

Prevalence of Rheumatoid Arthritis and Spondyloarthritis in Turkey: A Nationwide Study

Objectives This study aims to estimate the prevalence of rheumatoid arthritis (RA) and spondyloarthritis (SpA) in Turkey using the same telephone questionnaire developed for screening RA and SpA in France and used in Serbia and Lithuania. Material and methods The study was performed in two steps. In step I, the French questionnaire was translated into Turkish and validated through a group of 200 patients (80 males, 120 females; mean age 44.0±13.1 years; range 19 to 75 years) followed up at the rheumatology departments of University Hospitals in Antalya and Ankara. In step II, the validated Turkish questionnaire was administered face-to-face to randomly selected 4,012 subjects (1,670 males, 2,342 females; mean age 41.5±16.8 years; range 16 to 97 years) by trained general practitioners across the country, in 25 prov- inces for case detection. The subjects who were suspected of having RA or SpA in accordance with the questionnaire were invited to the nearest university hospital for rheumatologic examination in order to confirm the diagnosis. Results In step II, a total of 25 subjects (2 males, 23 females) were diagnosed as RA. The standardized RA prevalence for the general population of Turkey was calculated as 0.56% (95% confidence interval [CI]; 0.33-0.79), 0.10% (95% CI; -0.05-0.25) for males and 0.89% (95% CI; 0.51-1.27) for females. A total of 18 subjects (3 males, 15 females) were diagnosed as SpA. The standardized SpA prevalence for the general population of Turkey was 0.46% (95% CI; 0.25-0.67), 0.17% (95% CI; -0.03-0.37) for males and 0.65% (95% CI; 0.32-0.98) for females. The prevalence of RA was highest in the Northern region (2.00%) and the prevalence of SpA was highest in the Central region (1.49%). Conclusion The prevalences of RA and SpA in Turkey are close to each other and there are significant inter-regional variations in prevalences of both RA and SpA.

The influence of monocular vision on the plantar pressure distribution

BACKGROUND Although the influence of monocular vision to upper limb biomechanics has been well documented, data about lower extremity biomechanics are limited. The objective of the present study was to demonstrate pedobarographic differences between both feet of the individuals with monocular vision in static and dynamic conditions. METHODS Pedobarographic analysis of twenty-four participants with monocular vision was performed. Relative static pressure load (%) and dynamic peak plantar pressure (N/cm(2)), force (N) distributions and contact area percentages (%) were recorded under both low vision and normal vision side foot. FINDINGS The results showed that relative static pressure loads did not differ between low vision and normal vision foot. Under midfoot of low vision side, a significant increment was found in peak plantar pressures (2.42 (SD 1.09) N/cm(2)) and forces (136.77 (SD 64.96) N) compared to normal vision side foot (1.87 (SD 0.96) N/cm(2); 106.94 (SD 65.03) N). No difference in contact area percentages was detected. INTERPRETATION These results indicate that there are differences in plantar pressure measurements between feet of individuals with monocular vision. These pedobarographic differences reported here appear to support the assumption that individuals with monocular vision have adaptive gait strategies such as, decreased walking speed, limited ankle motion and postural compensations.

Influence of patient training on persistence, compliance, and tolerability of different dosing frequency regimens of bisphosphonate therapy: An observational study in Turkish patients with postmenopausal osteoporosis

Objective In our study, we aimed to evaluate the influence of training on compliance and persistence with bisphosphonate treatment given on a weekly vs. monthly basis in postmenopausal osteoporosis patients. Methods A total of 979 patients with postmenopausal osteoporosis (mean age: 63.2 ± 7.2 years) were included in this national, multicenter, prospective non-interventional observational cohort registry study. Patients were randomized into training (n = 492, 50.3%, mean age: 63.4 ± 7.2 years) and control (n = 487, 49.7%, mean age: 63.0 ± 7.1 years) groups. Patients in each intervention group were given weekly (44.9% and 44.6% for training and control subjects, respectively) or monthly (55.1% and 55.4%, respectively) bisphosphonate regimens. After the initial visit, patients were followed up at three-month intervals throughout 12 months of treatment for evaluation of persistence, compliance and adverse events. Results On average, 79.4% of the patients were persistent with the treatment with a mean of 350.4 days of duration during the 12-month follow-up period. The mean compliance in the compliant and fully compliant group remained at an average of 86.6%. No significant difference was detected between the training and control groups in terms of compliance and persistence. Significantly longer persistence (360.0 ± 89.0 vs. 345.0 ± 108.0 days; p = 0.035), higher percentage of persistent patients (83.4% vs. 74.2%; p = 0.012) and higher compliance rates (88.8% vs. 83.3%; p = 0.002) were noted in monthly regimen patients in comparison to those given weekly regimen. Conclusion Our findings revealed remarkably high rates for persistence and compliance with bisphosphonate treatment in postmenopausal osteoporosis, with no impact of training on compliance and persistence rates. Longer persistence and better compliance rates were achieved with the monthly bisphosphonate regimen when compared to the weekly regimen.
