The evaluation of quality of life in fibromyalgia syndrome: a comparison with rheumatoid arthritis by using SF-36 Health Survey

Musculoskeletal disorders are the most common causes of deterioration in quality of life (QOL). We in this study aimed to assess (1) the impact of fibromyalgia syndrome (FS) on QOL comparing with that of rheumatoid arthritis (RA) patients and control subjects and (2) the impact of these two musculoskeletal disorders on various components of QOL using SF-36 Health Survey. Thirty-five patients with RA, 30 patients with FS, and 30 voluntary control subjects were included in the study. The groups were comparable in terms of demographic characteristics. QOL was evaluated by using Short-Form (SF)-36 Health Survey in all study participants, and Fibromyalgia Impact Questionnaire (FIQ), which is a specific health-status instrument for FS, was used in FS patients. Physical functioning, physical role, social functioning, bodily pain, general health, vitality, emotional role, and mental health scores were significantly lower in RA and FS patients than in control subjects (p<0.05). The between-groups comparisons revealed that FS patients had significantly lower mental health scores than RA patients (49.87 vs 62.51, respectively), (p<0.001). Total FIQ score correlated significantly with physical functioning, physical role, and bodily pain in FS patients. All parameters of SF-36 Health Survey except for social functioning correlated significantly with some of the variables of FIQ. FS has a negative impact on QOL, like RA. Furthermore, mental health was more severely affected in FS patients when compared with RA patients.

Effectiveness of pulsed electromagnetic field therapy in lateral epicondylitis

We aimed to investigate the efficacy of pulsed electromagnetic field (PEMF) in lateral epicondylitis comparing the modality with sham PEMF and local steroid injection. Sixty patients with lateral epicondylitis were randomly and equally distributed into three groups as follows: Group I received PEMF, Group II sham PEMF, and Group III a corticosteroid + anesthetic agent injection. Pain levels during rest, activity, nighttime, resisted wrist dorsiflexion, and forearm supination were investigated with visual analog scale (VAS). Pain threshold on elbow was determined with algometer. All patients were evaluated before treatment at the third week and the third month. VAS values during activity and pain levels during resisted wrist dorsiflexion were significantly lower in Group III than Group I at the third week. Group I patients had lower pain during rest, activity and nighttime than Group III at third month. PEMF seems to reduce lateral epicondylitis pain better than sham PEMF. Corticosteroid and anesthetic agent injections can be used in patients for rapid return to activities.

Discriminative Value of Tender Points in Fibromyalgia Syndrome

OBJECTIVE The aim of this study is to assess the discriminative value of all tender points, alone and in combination, that are designated as criteria for fibromyalgia diagnosis by the American College of Rheumatology (ACR), by investigating the appropriate pressure magnitude that should be applied during tenderness examination. DESIGN Cross-sectional. PATIENTS This study was performed on 66 patients with fibromyalgia diagnosed according to ACR classification criteria and 50 control subjects. SETTING The outpatient rheumatology clinic of a PM&R department of a university hospital. Intervention. Pressure pain threshold values were measured by a dolorimeter on nine specific point pairs in both groups and a cutoff value for discriminating positivity and negativity was calculated for each. Then the most valuable tender point pairs were assessed for discrimination of fibromyalgia syndrome using ACR criteria set as a reference standard. RESULTS All tender points with determined pressure cutoff values were found out to significantly discriminate fibromyalgia syndrome and their area under curve values ranged from 0.779 to 0.934. Univariate logistic regression analysis revealed that lateral epicondyle and supraspinatus point pairs had the most powerful discriminative ability (odds ratio = 113.6 and 45.0, respectively). Multiple logistic regression analysis with backward stepwise method showed that lateral epicondyle and second rib point pairs were most discriminative with sensitivity and specificity rates of 87.9-94.0% and 77.3-84.0%, respectively. CONCLUSIONS Fibromyalgia syndrome can have potential to be recognized simply by pressing fewer tender point areas but with various pressure cutoff levels identified for each tender point areas.

The efficacy of linear polarized polychromatic light on burn wound healing : An experimental study on rats

We aimed to investigate the questionable effect of linear polarized polychromatic light on burn wound healing in rats. Two deep second-degree burn wounds on the backside of each of 21 Sprague-Dawley rats were created with a standard burning procedure by applying a heated plaque. Burned regions located right dorsolaterally and classified as group I lesions were treated with linear polarized polychromatic light + open dressing + antibacterial pomade, whereas group II lesions were located left dorsolaterally and treated with only open dressing + antibacterial pomade. Macroscopic evaluation was performed for determination of the completed wound closure rate, measurement of burn wound area, and investigation of macroscopic edema, hyperemia, and epithelialization. Histopathological evaluation included monitoring of epithelialization, vascularization, origination of granulation tissue, inflammatory cell response, and total histopathological score on days 7, 14, and 21 after burn creation. Macroscopic evaluation revealed more obvious epithelialization in group I lesions between days 6 and 15. The number of completely closed wounds was higher in group I than in group II on days 16 and 21. The average area of burn wounds was lower from day 5, hyperemia was less on days 2 to 17, and edema was less from day 4 to day 13 in group I lesions. Histopathological evaluation revealed a higher rate of epithelialization on day 7 and higher vascularization occurrence on day 21 in group I lesions. Linear polarized polychromatic light seems to be effective in the treatment of burn wounds and in the promotion of healing. This may be related to linear polarized polychromatic light stimulation of epithelialization and vascularization.

Arm span-height difference is not an indicator of osteoporosis or associated vertebral deformity in postmenopausal women.

We studied ninety postmenopausal women who were suspected of having osteoporosis and aimed to investigate if ’arm span‐height difference’ value can help to estimate osteoporosis or related vertebral fractures. Osteoporosis was found in 51 of the patients. There was no statistical difference between osteoporotic and nonosteoporotic patients for ’arm span‐height’ value (p is less than 0.05). No statistical difference was determined between total Kleerekoper score and ’arm span‐height difference’ value (p is less than 0.05). It did not seem convenient to estimate the presence of osteoporosis and related fractures by the help of ’arm span‐height difference’ value.

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.
