Translation and validation of the Turkish version of the Ankylosing Spondylitis Quality of Life (ASQOL) questionnaire.

The Ankylosing Spondylitis Quality of Life (ASQoL) questionnaire is a disease-specific measure of needs-based quality of life developed in the UK and the Netherlands. This study describes translation, validation, and reliability of the scale into Turkish population. The ASQoL was translated into Turkish using the dual-panel process. Content validity was assessed via cognitive debriefing interviews with ankylosing spondylitis (AS) patients. Patients with AS according to modified New York criteria were recruited into the study from 12 hospitals of all part of Turkey. Psychometric and scaling properties were assessed via a two administration survey involving the ASQoL, the Nottingham Health Profile (NHP), Bath AS Functional Index (BASFI), and Bath AS Disease Activity Index (BASDAI). Classical psychometrics assessed reliability, convergent validity (correlation of ASQoL with NHP, BASFI, and BASDAI) and discriminative validity (correlation of ASQoL with perceived AS-severity and general health). Cognitive debriefing showed the new Turkish ASQoL to be clear, relevant, and comprehensive. Completed survey questionnaires were received from 277 AS patients (80% Male, mean age 42.2/SD 11.6, mean AS duration 9.4 years/SD 9.4). Test-retest reliability was excellent (0.96), indicating low random measurement error for the scale. Correlations of ASQoL with NHP sections were low to moderate (NHP Sleep 0.34; NHP Emotional Reactions 0.83) suggesting the measures assess related but distinct constructs. The measure was able to discriminate between patients based on their perceived disease severity (p < 0.0001) and self-reported general health (p < 0.0001). The Turkish version of ASQoL has good reliability and validity properties. It is practical and useful scale to assess the quality of life in AS patients in Turkish population.

Can the patient-reported outcome instruments determine disease activity in rheumatoid arthritis?

OBJECTIVES: The aim of this study was to investigate the indicative value of the patient-reported outcome instruments (PROs) on disease activity in rheumatoid arthritis (RA). METHODS: Three hundred sixty eight patients with RA were included in this cross-sectional study. Disease activity was evaluated using both the Disease Activity Score 28 (DAS 28) and the Clinical Disease Activity Index (CDAI). Patients who had DAS 28 score < 3.60 points and CDAI score <10.00 points were allocated into the "low disease activity" group and those who had DAS 28 score > or = 3.60 points and CDAI score > or = 10.00 points into the "moderate or high disease activity" group. The Health Assessment Questionnaire (HAQ), Nottingham Health Profile (NHP), Rheumatoid Arthritis Quality of Life (RAQoL), and Short Form 36 (SF 36) were used as PROs. Logistic regression analysis was used to find variables, which had an indicative value for disease activity. RESULTS: HAQ, pain and emotional reaction subscales of NHP, and bodily pain, general health and social functioning subscales of SF 36 had independent indicative values, when DAS 28 was used as dependent variable. On the other hand, HAQ, pain and emotional reaction subscales of NHP, and general health and emotional role limitation subscales of SF 36 had indicative values when CDAI was used as dependent variable. DAS 28 and CDAI both showed HAQ as the parameter with the highest odds ratio (OR). But RAQoL had shown no independent indicative value for projecting disease activity. CONCLUSION: It was concluded that HAQ could determine disease activity in RA better than other PROs included in this study (Tab. 4, Ref. 36).

Comparison of lidocaine injection, botulinum toxin injection, and dry needling to trigger points in myofascial pain syndrome.

BACKGROUND: Myofascial pain syndrome (MPS) is one of the most common causes of chronic musculoskeletal pain. Several methods have been recommended for the inactivation of trigger points (TrP). OBJECTIVES: This prospective, single-blind study was proposed to compare TrP injection with botulinum toxin type A (BTX-A) to dry needling and lidocaine injection in MPS. METHODS: Eighty-seven trigger points (cervical and/or periscapular regions) in 23 female and six male patients with MPS were treated and randomly assigned to three groups: lidocaine injection (n=10, 32 TrP), dry needling (n=10, 33 TrP), and BTX-A injection (n=9, 22 TrP). OUTCOME MEASURES: Clinical assessment including cervical range of motion, TrP pain pressure threshold (PPT), pain scores (PS), and visual analog scales for pain, fatigue, and work disability were evaluated at entry and the end of the 4th week. Additionally, depression and anxiety were evaluated with the Hamilton depression and anxiety rating scales, and quality of life was assessed using the Nottingham health profile (NHP). The subjects were also asked to describe side effects. INJECTION PROCEDURE: One milliliter of 0.5% lidocaine was administered to each TrP in the lidocaine injection group, 10-20 IU of BTX-A to each TrP in the BTX-A group, and dry needling to each TrP in the last group, followed by stretching of the muscle groups involved. The patients were instructed to continue their home exercise programs. RESULTS: Pain pressure thresholds and PS significantly improved in all three groups. In the lidocaine group, PPT values were significantly higher than in the dry needle group, and PS were significantly lower than in both the BTX-A and dry needle groups. In all, visual analog scores significantly decreased in the lidocaine injection and BTX-A groups and did not significantly change in the dry needle group. Disturbance during the injection procedure was lowest in the lidocaine injection group. Quality of life scores assessed by NHP significantly improved in the lidocaine and BTX-A groups but not in the dry needle group. Depression and anxiety scores significantly improved only in the BTX-A-injected group. CONCLUSIONS: Injection is more practical and rapid, since it causes less disturbance than dry needling and is more cost effective than BTX-A injection, and seems the treatment of choice in MPS. On the other hand, BTX-A could be selectively used in MPS patients resistant to conventional treatments.

Spinal epidural hematoma associated with streptokinase treatment for myocardial infarction.

STUDY DESIGN: Case Report. OBJECTIVE: Thrombolytic therapy has become a routine and valuable care for selected patients with acute myocardial infarction (AMI) and rarely complicates with spinal epidural hemorrhage causing cord compression. SETTING: Elazig, Turkey CASE REPORT: A 72-year-old woman developed spinal epidural hemorrhage following streptokinase and heparin administration for AMI. Back pain and lower extremity neurologic deficits ensued secondary to spinal cord compression by epidural hematoma. Diagnosis of spinal epidural hematoma, extending through T11 to L2 vertebra levels, could be accurately made by magnetic resonance imaging (MRI). Careful follow-up by neurologic examination, reversal of anticoagulant effects, anti-edema treatment with steroids and a low-intensity rehabilitation program maintained a full recovery. Follow-up MRI, 3 months after the accident, revealed complete resolution of the hematoma. CONCLUSION: Physicians should be aware of this rare complication secondary to thrombolytic therapy. A high index of suspicion for hemorrhagic complications is necessary, particularly in elderly patients under thrombolytic treatment regardless of spinal pain, and the patient's lethargic or confused status should be taken into account. MRI is a valuable imaging option that gives information on both localization and extent of lesion and recovery.

Auditory P300 event related potentials and serotonin reuptake inhibitor treatment in patients with fibromyalgia.

BACKGROUND: The P300 components of auditory event related potentials (ERPs) are objective measures related to information and cognitive processing. OBJECTIVES: To assess P300 ERPs in female patients with fibromyalgia (FM) in comparison with healthy age matched controls. To investigate the relationship between P300 potentials and pain threshold levels of patients, and subsequent effect of sertraline treatment on P300 potentials. METHODS: P300 auditory ERPs were studied in 13 untreated female patients with FM and 10 healthy controls matched for age, sex, and education. Pain pressure thresholds and total myalgic scores (TMS) were assessed with an algometer. Patients were evaluated for clinical measures and P300 potentials (recorded from the vertex) at the first visit, and then in the fourth and eighth weeks of sertraline treatment. RESULTS: Patients with FM had significantly lower P300 amplitudes, but not significantly different P300 latencies, than controls at entry. P300 latencies in patients correlated negatively with TMS (r(s)=-0.79, p<0.01) and P300 amplitudes correlated significantly with TMS (r(s)=0.53, p<0.05). Anxiety and depression scores did not correlate significantly with P300 latencies or amplitudes at the study entry. P300 auditory ERPs had increased amplitudes that had reached nearly the same levels as those of the controls at the eighth week without any significant change in their latencies. CONCLUSION: The results show reduced P300 amplitudes in patients with FM. Further studies assessing the relationship between P300 ERPs and neuropsychiatric tests are required for better clarification of the clinical relevance of P300 potentials in FM.

Relationship between chest expansion and respiratory muscle strength in patients with primary fibromyalgia.

In this paper the assessment of the relationship between chest expansion with maximal inspiratory (MIP) and expiratory pressures (MEP) in primary fibromyalgia (FM) syndrome is discussed. Chest expansion (CE) measurements, spirometric values, and MIP and MEP values in 30 female patients with primary FM are compared with 29 healthy age-matched female controls. Patients with FM had lower CE, MEP and MIP values than controls. CE correlated significantly with MIP and MEP values. There was no significant difference between groups in spirometric values. Our results indicate that patients with FM have impaired respiratory muscle strength, and measurement of CE may be a useful clinical parameter. Despite its limitations CE may reflect respiratory muscle strength. It is worth following up these data in a wider and controlled series, with ancillary tests in addition to the MIP and MEP.

Pseudothrombophlebitis in a patient with Behçet's syndrome: Doppler ultrasound and magnetic resonance imaging findings.

A 33-year-old man with a known diagnosis of Behçet's syndrome (BS), presented with pseudothrombophlebitis resulting from acute rupture of a popliteal cyst. Doppler ultrasound and magnetic resonance imaging findings are explained. Differentiation of rupture of a Baker's cyst from true thrombophlebitis, especially in patients with BS, who are potentially susceptible to thrombotic events, is extremely important.

Relationship between bone mineral density and radiologic scores of hands in rheumatoid arthritis.

This study proposed to assess the relationship between hand bone mineral density (BMD) and radiographic scoring methods, important measures to assess the course of rheumatoid arthritis. Hand, spine, and femur BMD of 49 patients with rheumatoid arthritis and 34 age- and sex-matched healthy control subjects were measured using dual X-ray absorptiometry and the results were compared. Standard hand films of patients were scored according to five different scoring methods--Larsen method, modified Larsen method, Sharp/van der Heijde modified method, carpo:metacarpal ratio, and simple erosion narrowing score (SENS)--and were correlated with hand BMD. There was a moderate relationship between hand BMD measurements and radiologic scores. SENS was the method that correlated significantly with the highest correlation coefficient. Hand BMD correlated significantly with disease duration and c-reactive protein levels. Hand BMD in patients with rheumatoid arthritis was significantly lower than in control subjects, whereas there was no significant difference in axial BMD measurements. The advantages and disadvantages of hand BMD and radiographic scoring methods were determined. Our results indicate that hand BMD measurements may be as useful is assessing the course of rheumatoid arthritis as radiologic scoring methods. However to prove this, a well-designed reference population for hand BMD and longitudinal studies are required.

Dactylitis in a patient with brucellosis.

Dactylitis is an important feature of inflammatory arthritis and unusual complication of osteoarticular brucellosis. We report a case of dactylitis of the index finger in a female patient with brucellosis.

Paravertebral abscess formation due to brucellosis in a patient with ankylosing spondylitis.

It is occasionally difficult to distinguish the features of spinal brucellosis from those of ankylosing spondylitis (AS), and the resultant delayed diagnosis may allow insidious progression of the complications of the brucella infection. The case of a 33-year-old male HLA-B27-positive patient with known diagnosis of AS for 7 years, who developed a paravertebral abscess in the left erector spinae muscle due to brucellosis, is presented in this paper. This case report illustrates two important points; first, co-occurrence of AS and brucellosis in the same patient, and second, posterior element involvement with abscess formation in erector spinae muscle, which has not been previously reported. Magnetic resonance imaging is a sensitive method for detecting spinal brucellosis and extent of infection throughout paravertebral structures. Clinicians serving patients from areas with endemic brucellosis should not overlook the possibility of this infection in the presence of axial musculoskeletal symptoms, even among patients with AS.

Lipid profile in patients with fibromyalgia and myofascial pain syndromes.

In this study serum lipid profile of patients with fibromyalgia syndrome (FMS) and myofascial pain syndrome (MPS) were investigated and compared with healthy controls. Thirty women who had FMS and 32 women who had MPS with the characteristic trigger points (TrP), especially on the periscapular region were included in this study. Thirty one age matched healthy women were assigned as a control group. All of the subjects were sedentary healthy housewives. Total cholesterol, triglyceride and high-density lipoprotein cholesterol (HDL-c) levels were not significantly different between the FMS and control groups. On the other hand the MPS group had total cholesterol (198.7 vs 172.9 mg/dL, p=0.003), triglyceride (124.7 vs 87.6 mg/dL, p=0.01), low-density lipoprotein cholesterol (LDL-c) (127.5 vs 108.4 mg/dL, p=0.02) and very low-density lipoprotein cholesterol (VLDL-c) (24.9 vs 17.3 mg/dL, p=0.008) levels, which were significantly higher than the controls. There was no significant difference between the lipid profiles in the FMS and MPS groups. Tissue compliance, which was measured from trigger points in the MPS group, correlated significantly with total cholesterol and LDL-c levels. In conclusion, a significant difference was found between the lipid levels of patients with MPS and the controls. More extensive investigation of lipid and lipoprotein levels is required to determine whether high lipid levels are the cause or result of MPS.

Odontoid fracture complicating ankylosing spondylitis.

Patients with ankylosing spondylitis are prone to fractures. We describe a 32-year-old male patient with an odontoid fracture and anterior dislocation of C1 vertebra relative to C2 complicating ankylosing spondylitis. The importance and difficulties of the rehabilitation program are stressed. The role of magnetic resonance imaging and three-dimensional computerized tomography in diagnosis is emphasized.

The relationship of clinical and laboratory measurements to two different radiological scoring methods in ankylosing spondylitis.

Two different methods for scoring the severity of radiological changes in 19 patients with ankylosing spondylitis, using plain X-rays of the lumbar spine and sacroiliac (SI) joints, were assessed in relation to clinical and laboratory measurements. Bath Ankylosing Spondylitis Radiology Index (BASRI) and Stoke Ankylosing Spondylitis Spine Score (SASSS) were used to evaluate radiologic changes. Disease activity was assessed using Bath Ankylosing Spondylitis Disease Activity Index (BASDAI). There was no correlation between duration of morning stiffness, night pain, laboratory variables (ESR, CRP, hemoglobin, platelets) and any of the radiological scores. No significant correlation was found between BASDAI and both of the radiological scores. BASRI and SASSS correlated significantly with occiput-to-wall distance, Schober test, and finger-to-fibula distance. There was no significant correlation of radiologic scores with finger-to-floor distance and chest expansion. Right and left SI joint scores correlated significantly with BASRI and SASSS. The good correlation between spinal indexes and lack of correlation between clinical indicators of disease activity supports the notion that these two radiological scoring methods are measures of disease severity or deformity rather than disease activity. Radiological scoring methods are fundamental for the diagnosis and progression in AS and BASRI may be a more practical and appropriate method.

Correlation of hand bone mineral density with the metacarpal cortical index and carpo:metacarpal ratio in patients with rheumatoid arthritis.

This study proposed an assessment of the correlation of hand bone mineral density measured by dual energy x-ray absorbtiometry (DXA) with the carpo:metacarpal (C:MC) ratio and metacarpal cortical index (CI) in patients with rheumatoid arthritis (RA). The correlation of total hand BMD, CI and C:MC ratio with BMD at other sites, the Health Assessment Questionnaire (HAQ) and Larsen scores were also examined. The hand and axial BMD of 30 female patients were also compared with 29 age-matched healthy female controls. Total hand BMD values of patients were significantly lower than the control group. There was no significant difference between groups in axial measurements. CI correlated moderately with the second metacap (II.MC) midshaft and total hand BMD. The C:MC ratio correlated with II.MC midshaft and total hand BMD. Total hand BMD correlated moderately with the AP spine (L2-L4) and femoral neck BMD. Larsen scores showed weak negative correlation with II.MC midshaft BMD and CI. Grip strength correlated weakly only with total hand BMD. The results indicated that CI may reflect cortical bone mass of the hand accurately and did not predict bone density of the spine or hip in patients with RA. The C:MC ratio is a useful method for evaluating progression of wrist involvement and may be related to the loss of hand bone mineral density associated with disease process.

Brucella disc infection mimicking lumbar disc herniation: a case report.

Brucellosis is a zoonotic disease and still a major health problem in many geographical areas. In this paper a forty year-old woman with spinal brucellosis associated with epidural abscess formation and mimicking lumbar disc herniation is presented. Compression of spinal nerve root(s) by epidural masses due to brucella disc infection is a rare condition and should be kept in mind in differential diagnosis of lumbar disc herniation. The crucial role of magnetic resonance imaging in differential diagnosis is also emphasised.
