The Association of Skinfold Anthropometric Measures, Body Composition and Disease Severity in Obese and Non-obese Fibromyalgia Patients: A Cross-sectional Study.

OBJECTIVES: This study aims to determine the effects of obesity and obesity related anthropometric and body composition determiners on the severity of fibromyalgia syndrome (FS) and to compare obese, overweight and normoweight FS patients according to general health and psychological status. PATIENTS AND METHODS: The study included 42 obese (mean age 48.8±11.6; range 24 to 65 years), 27 overweight (mean age 47.3±3.4; range 24 to 61 years) and 32 normoweight (mean age 47.1±7.8 years; range 31 to 60 years) female FS patients. Widespread pain scores and symptom severity scores were noted. Pain pressure thresholds of tender points and control points were measured and total myalgic score (TMS) was calculated. The anthropometric assessments and skinfold measurements of all participants were recorded. Quality of life was evaluated by Health Assessment Questionnaire while psychological status was evaluated using Beck Depression Inventory. RESULTS: Control points, TMS values and hand grip strength values of obese FS patients were significantly lower, while disease duration, symptom severity, widespread pain scores, visual analog scale and Health Assessment Questionnaire scores were significantly higher than normoweight and overweight FS patients. Fat free mass, fat mass, body fat percentage and waist/hip ratio values were significantly higher in obese FS patients than overweight and normoweight FS patients (p<0.001 for all values). Stepwise linear regression analysis showed that increased body mass index, decreased fat free mass (R2=0.11) and increased disease duration (R2=0.13) were associated with lower TMS. CONCLUSION: We found that obesity had significant negative effects on pain, disease severity and quality of life in patients with FS.

"Managing" the Placebo Effect: The Single-Blind Placebo Lead-in Response in Two Pain Models.

OBJECTIVE: "Placebo effects" in analgesic medication trials for chronic pain are pervasive; however, little is known regarding mechanisms or factors that may influence the presence or magnitude of these effects. Our objective is to consider elements of the placebo response in the context of two pain models using a "single-blind placebo lead-in" design (SBPLI). METHODS: As part of two pilot drug trials using knee osteoarthritis (KOA) and non-radicular low back pain (LBP) subjects, SBPLI protocols were conducted. We examined whether gender and/or diagnosis affected placebo responses as observed in changes in patient self-reported pain, depressive and pain anxiety symptoms. We also evaluated the placebo response on performance-based tests (stair climbing, range of motion (ROM), sit to stand repetitions, and 6-minute treadmill distance). RESULTS: VAS Pain Intensity (Now) values decreased significantly during the SBPLI for the sample as a whole, but the effects appeared stronger among LBP subjects. CES-D short form values (depressive symptoms) did not decrease significantly during the SBPLI for the sample as a whole, but some placebo effects appeared to emerge for women in the KOA group. PASS values (pain anxiety symptoms) decreased significantly, albeit mildly, during the SBPLI for the sample as a whole.Stair Climb (time) revealed no significant SBPLI effects. Bend Forward to Floor (ROM) increased significantly at the end of the SBPLI period for the sample as a whole, but the effects appeared stronger among KOA subjects. Sit to Stand Repetitions increased during the SBPLI for the sample as a whole. Treadmill Distance did not change significantly from Visit 1 to Visit 2; however, a significant Sex difference for the KOA group was found such that women showed greater Treadmill Distance at Visit 2. CONCLUSION: Placebo effects emerged across psychometric and performance-based measures, indicating the pervasiveness of this phenomenon. In this design, diagnostic and (to a lesser extent) gender categories differentials were observed during the placebo period. The SBPLI design may prove not only a robust method in studying the placebo phenomena, but also as a design element to mitigate some aspects of the placebo response in clinical trials.

The osteoarthritis knee model: psychophysical characteristics and putative outcomes.

UNLABELLED: The knee osteoarthritis (KOA) model is a convenient and coherent archetype that is frequently used in pharmaceutical trials of drugs with analgesic and/or anti-inflammatory properties; yet, little is known about its specific pathophysiology. The presumed chronic inflammatory etiology of osteoarthritis suggests that nociceptive processes and neurogenic inflammation predominate in this condition. However, most chronic pain conditions are associated with changes in peripheral and central processing. Recent data corroborate this as an important mechanism in KOA. We compared psychophysical characteristics (including thermal Quantitative Sensory Testing); thermal, mechanical, and functional wind-up; thermal and mechanical aftersensations; and pressure algometry of 37 subjects with KOA with 35 age- and sex-matched controls. A third of the KOA subjects demonstrated hypoesthesia to vibration and the 4.56 von Frey fiber, yet few showed allodynia in their worse knee. The majority of subjects had abnormalities to pinprick (41% were hyperalgesic and 27% were hypoesthetic). Compared to controls, the more painful knee was hypoesthetic to cold detection and had greater thermal wind-up, lower pressure-pain thresholds, thermal and mechanical aftersensations, and twice the pain ratings of controls after stair climb. Substantial intraindividual differences were found in KOA subjects and controls for mechanical wind-up and algometric thresholds. PERSPECTIVE: These results develop the KOA model and suggest mechanistic hypotheses. Certain of these tests may ultimately prove to be responsive, quasi-objective, and quantitative outcomes for research and lend empirical support to the notion of measurable sensitization in osteoarthritis.

The effects of coexisting fibromyalgia syndrome on pain intensity, disability, and treatment outcome in patients with chronic lateral epicondylitis.

OBJECTIVE: The objective of this study was to evaluate the effects of coexisting fibromyalgia syndrome (FS) on pain intensity, disability, and treatment outcome in patients with chronic lateral epicondylitis (LE). METHODS: Seventy-eight patients with chronic unilateral LE and 30 healthy subjects were included. Patients were classified into two groups: group 1 consisted of 46 LE alone patients, while group 2 consisted of 32 LE plus FS patients. A pain questionnaire was used to determine the subjective pain and disability. Pressure pain threshold (PPT) on the lateral epicondyles, isometric hand grip strength (IHGS), lateral pinch grip strength (LPGS), and tender point examinations of groups were performed. A mixture of methylprednisolone and prilocaine was injected 1 cm distal to the lateral epicondyle. All measurements were repeated 2 weeks and 3 months after injection. RESULTS: Compared with healthy subjects, both patient groups had significantly increased pain and disability scores and decreased IHGS, LPGS, and PPT values (P < 0.001). Compared with the LE alone group, pain and disability scores were significantly higher (P < 0.01), and PPT, IHGS, and LPGS values were significantly lower in LE plus FS group (P < 0.05). Pain questionnaire scores of the LE alone and LE plus FS patients showed statistically significant decrease, and IHGS, LPGS, and PPTs showed statistically significant increase at the second week (P < 0.01) and at the third month (P < 0.001) after injection. Improvements in the LE plus FS group were poorer than FS alone group at both second week and third month after injection. CONCLUSION: Coexisting FS may increase the pain intensity and disability, and negatively affect the treatment outcome in patients with chronic LE.

Cycling progressive resistance training for people with multiple sclerosis: a randomized controlled study.

OBJECTIVE: To evaluate the effects of cycling progressive resistance training combined with balance exercises on walking speed, balance, fatigue, fear of falling, depression, and quality of life in patients with multiple sclerosis. DESIGN: In this prospective randomized controlled trial, 45 patients were randomized into two exercise training (n = 30) groups and one control (n = 15) group. The patients in training group 1 (n = 15) underwent progressive resistance training on a bicycle ergometer and balance exercise, whereas group 2 (n = 15) patients received a home-based lower-limb strengthening and balance exercise. Outcome measures, including the duration of exercise, tolerated maximum workload, timed up and go test, Dynamic Gait Index, functional reach, Falls Efficacy scale, 10-m walk test, Fatigue Severity Scale, Beck Depression Inventory, and Short Form 36 scores, were assessed initially and at 8 wks. RESULTS: After dropouts, the whole study group consisted of 20 women and 13 men (mean age, 37.9 +/- 10.43 yrs). In training group 1, duration of exercise, tolerated maximum workload, timed up and go test, Dynamic Gait Index, functional reach, falls efficacy scale, 10-m walk test, Fatigue Severity scale, and Beck Depression Inventory scores, and in group 2, the mean duration of exercise, tolerated maximum workload, and Falls Efficacy scale scores were significantly improved after the training program (P < 0.05). There were no significant improvements in any of the outcome measurements in the control group (P > 0.05). In between-group comparisons, improvements in outcome measures of group 1 patients were significantly higher than those in other groups, except for 10-m walking test. Group 1 patients showed statistically significant improvement in physical functioning and role-physical functioning scales of the Short Form 36 (P < 0.01 and P < 0.05, respectively), and group 2 patients showed statistically significant improvement in only physical functioning scale of Short Form 36 (P < 0.05) after 8 wks. CONCLUSIONS: Specific exercise programs, including cycling progressive resistance training, may improve balance, fatigue, and depression and reduce fear of falling in patients with multiple sclerosis without worsening multiple sclerosis signs and symptoms.

The effects of incremental speed-dependent treadmill training on postural instability and fear of falling in Parkinson's disease.

OBJECTIVE: To detect the effectiveness of incremental speed-dependent treadmill training on postural instability, dynamic balance and fear of falling in patients with idiopathic Parkinson's disease. DESIGN: Randomized controlled trial. SETTING: Ankara Education and Research Hospital, 2nd PM&R Clinic, Cardiopulmonary Rehabilitation Unit. SUBJECTS: Fifty-four patients with idiopathic Parkinson's disease in stage 2 or 3 of the Hoehn Yahr staging entered, and 31 patients (21 training, 10 control) had outcome data. INTERVENTIONS: Postural instability of patients with Parkinson's disease was assessed using the motor component of the Unified Parkinson's Disease Rating Scale (UPDRS), Berg Balance Test, Dynamic Gait Index and Falls Efficacy Scale. Twenty-one patients with Parkinson's disease participated in an eight-week exercise programme using incremental speed-dependent treadmill training. Before and after the training programme, balance, gait, fear of falling and walking distance and speed on treadmill were assessed in both Parkinson's disease groups. MAIN MEASURES: Walking distance and speed on treadmill, UPDRS, Berg Balance Test, Dynamic Gait Index and Falls Efficacy Scale. RESULTS: Initial total walking distance of the training group on treadmill was 266.45 +/- 82.14 m and this was progressively increased to 726.36 +/- 93.1 m after 16 training session (P < 0.001). Tolerated maximum speed of the training group on treadmill at baseline was 1.9 +/- 0.75 km/h and improved to 2.61 +/- 0.77 km/h (P < 0.001). Berg Balance Test, Dynamic Gait Index and Falls Efficacy Scale scores of the training group were improved significantly after the training programme (P < 0.01). There was no significant improvement in any of the outcome measurements in the control group (P > 0.05). CONCLUSIONS: Specific exercise programmes using incremental speed-dependent treadmill training may improve mobility, reduce postural instability and fear of falling in patients with Parkinson's disease.

The effects of sulfasalazine treatment on enthesal abnormalities of inflammatory rheumatic diseases.

The aim of this study was to evaluate the effects of a 1-year course of sulfasalazine monotherapy on enthesal abnormalities of inflammatory rheumatic diseases (IRDs) using ultrasonography. Thirty-six patients with IRD including 20 patients with rheumatoid arthritis (RA) and 16 patients with ankylosing spondylitis (AS) (22 women, 14 men, mean ages 43.3 +/- 8.8 years), and 18 healthy controls (10 women, 8 men, mean ages 42.5 +/- 9.9 years) matched by age and body mass index were enrolled in this study. For the evaluation of enthesal structures, all patients and controls underwent ultrasonographic (USG) examinations of five enthesal sites of both lower limbs using high-resolution and Doppler USG. An ultrasonographic score of lower limb enthesitis was calculated using Glasgow ultrasound enthesitis scoring system (GUESS). Clinical and laboratory activities of IRD patients were also evaluated. Patient group was made to undergo 2 g/day sulfasalazine monotherapy for 1 year. All evaluations were made at the beginning of the treatment and repeated after 1 year follow-up. Results showed that the frequency of enthesal abnormalities of the IRD group was significantly higher than controls. On USG examination, 301/1,296 (23.2%) enthesal structures were abnormal in IRD patients, and 19/648 (2.93%) structures were abnormal in controls. Mean GUESS score of the IRD group (6.40 +/- 2.41) was also significantly higher than controls (1.79 +/- 1.60) (p < 0.001). Although there was a significant improvement in clinical and laboratory activity parameters of the IRD patients, significant decrease was not observed in enthesal abnormalities (295/1,296 enthesal structures-22.7%) and mean GUESS score (6.20 +/- 2.38) after 1 year sulfasalazine trial. Additionally, there was no significant improvement in enthesal abnormalities and mean GUESS scores of AS and RA subgroups separately. Sulfasalazine treatment was not found effective on enthesal abnormalities of IRD patients. Further studies with larger groups including other IRDs are required to validate our results.

Complex regional pain syndrome type-I after rubella vaccine.

Complex regional pain syndrome type I (CRPS-I) is a complex disorder characterised by pain, autonomic dysfunction, and decreased range of motion. The syndrome was believed as a well-recognized disorder in adults but, less commonly recognized in children. CRPS-I after vaccination has been rarely reported. We reported an 11-year-old young girl with CRPS-I due to rubella vaccine.

Long-term ultrasonographic follow-up of plantar fasciitis patients treated with steroid injection.

OBJECTIVE: To evaluate the long-term efficacy of steroid injection for plantar fasciitis using clinical parameters and high-resolution ultrasonography. MATERIAL AND METHODS: Thirty patients (27 female and three male) with plantar fasciitis and 30 healthy controls matched by age, gender and body mass index (BMI), were enrolled in this study. Seventeen of the patients had bilateral and 13 had unilateral (six right, seven left) plantar fasciitis. Palpation-guided steroid injection was applied to the 47 heels of 30 plantar fasciitis patients. Ultrasound examination and pain intensity with visual analog scale (VAS) were assessed three times in each plantar fasciitis patients; before injection and at 1 and 6 months after steroid injection. Ultrasonography was performed to the controls at initial assessment. RESULTS: The plantar fascia was remarkably thicker in the plantar fasciitis group than in controls (P < 0.001). The thickness of the plantar fascia and mean VAS values in the plantar fasciitis group decreased significantly 1 month after steroid injection (P < 0.001, P < 0.001, respectively) and a further decrease was noted 6 months postinjection (P < 0.001, P < 0.001, respectively). Strong correlation was found between the changes of plantar fascia thickness and VAS values 1 month after (P < 0.001, r: 0.61) and 6 months after (P < 0.001, r: 0.49) steroid injection. The incidence of hypoechoic fascia was 73% in the plantar fasciitis group before steroid injection. It decreased significantly at 1 and 6 months postinjection (33% and 7%, respectively, P < 0.001). Gross fascia disruption or other side effects were not observed after steroid injection. CONCLUSION: Steroid injection could be used in plantar fasciitis treatment for its positive long-term effects.

Relationship between high-resolution computed tomography findings and the Stoke index in patients with rheumatoid arthritis.

The aim of this study was to evaluate the relationship between high-resolution computed tomography (HRCT) findings and the Stoke index (SI) in patients with rheumatoid arthritis (RA). Forty RA patients (31 women, 9 men) were evaluated. All patients fulfilled the criteria proposed by the American College of Rheumatology. Clinical evaluation, haematological data, chest radiography, pulmonary function tests (PFTs) and HRCT were obtained in all patients. The SI was used to assess disease activity. In 17 (42.5%) patients, there were no signs of pulmonary involvement on HRCT; 23 (57.5%) of 40 patients had abnormal HRCT findings. Of 23 patients with HRCT abnormalities, six (two male, four female) had respiratory symptoms, four (one male, three female) had abnormalities on chest radiography and five (all female) had abnormalities on PFTs. There was no relationship between pulmonary changes observed on HRCT, clinical and laboratory disease activity parameters, chest X-ray and PFTs. There was no difference in the mean SI between patients included in the HRCT (+) and those included in the HRCT (-) groups. No significant correlations between the HRCT and the SI were seen. The main findings of this study are that HRCT can give useful information on RA-associated lung changes and that there was no relationship between the SI and the HRCT findings of patients with RA.

The role of tendinitis in fibromyalgia syndrome.

Fibromyalgia Syndrome (FS) is a common disease characterized by diffuse, widespread pain and multiple tender points. The syndrome has been subclassified as primary (PFS) and secondary (SFS) fibromyalgia. The aim of this study was to evaluate the role of common tendinitis (rotator cuff tendinitis, bicipital tendinitis, lateral epicondylitis, De-Quervain's tendinitis and pes anserinus tendinitis) in FS. Twenty female patients with PFS, 20 with SFS and 20 female controls, matched by age and body mass index, participated in the study. Existence of common tendinitis was evaluated with specific examination methods. Right and left rotator cuff tendinitis, pes anserinus tendinitis and left lateral epicondylitis were significantly more common in patients with PFS and SFS than in control subjects. As a result, considering the central hyperexcitability present in the fibromyalgia patients, concomitant pathologies such as tendinitis which lead to shoulder, arm, and leg pain must be evaluated. Follow up and therapy for the disease must be planned according to these factors which are not only probable symptoms of FS, but also leading causes for the occurrence and continuity of the pain in this disease.

Seronegative spondyloarthropathy of familial Mediterranean fever.

Familial Mediterranean fever (FMF) is characterized by an autosomal inheritance pattern, Mediterranean ancestry, and history of recurrent fever. We present a 30-year-old Turkish man with FMF and accompanying seronegative spondyloarthropathy. His diagnose depended on the clinical course of his disease: recurrent fever accompanied by abdominal pain attacks together with a positive family history and his ethnic origin and sacroiliitis. We review the common manifestations of FMF and remind physicians that sacroiliac joint involvement must be kept in mind in presence of articular symptoms in a FMF patient.
