Assessment of the frequency of tarsal tunnel syndrome in rheumatoid arthritis.

OBJECTIVES: In this study, we aimed to determine the frequency of tarsal tunnel syndrome (TTS) in rheumatoid arthritis (RA) patients. PATIENTS AND METHODS: Thirty RA patients (1 male, 29 females; mean age: 41.9±10.1 years; range, 26 to 65 years) who met the American College Rheumatology (ACR) classification criteria and 20 healthy volunteers (1 male, 19 females; mean age: 39.3±10.8 years; range, 26 to 60 years) without any complaints between August 2006 and October 2007 were included in the study. Demographic characteristics of the study group were assessed and neurological examinations were performed. The Tinel's sign was checked to provoke the TTS symptoms. Disease severity was measured using Visual Analog Scale (VAS), Disease Activity Score-28 (DAS28), erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP). The health-related quality of life and disability status were determined using the Health Assessment Questionnaire (HAQ), Short Form 36 (SF-36), Foot Function Index (FFI), and VAS (0-100 mm). The positional relationship of the foot pain was questioned with VAS. The 100-m walking distance of the patient and control groups were calculated. RESULTS: Bilateral TTS was detected in 10 of the patients (33.3%) with rheumatoid arthritis. No relationship with the TTS disease duration, seropositivity, rheumatoid nodule, joint deformities, corticosteroid use, and DAS28 score were found. In correlation with TTS, foot and ankle joint were the first involved joints at the beginning of RA disease (p<0.005). The Tinel's sign was found to be 45% positive in patients with TTS. The 100-m walking time was significantly longer in RA patients compared to the control group (p<0.0001). CONCLUSION: Tarsal tunnel syndrome is commonly seen in RA and its incidence increases in patients with primary foot involvement. Therefore, caution should be taken against the entrapment neuropathies in these patients, and they should be supported by electrophysiological practices, when the diagnosis is necessary.

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.

Dynamic Thiol/Disulphide Homeostasis in Patients With Fibromyalgia.

OBJECTIVES: This study aims to investigate dynamic thiol/disulphide homeostasis in patients with fibromyalgia syndrome (FMS). PATIENTS AND METHODS: Fifty female patients with FMS (mean age 40.5±7.2 years; range 21 to 55 years) and 40 healthy female controls (mean age 39±9.4 years, range 22 to 55 years) were included in the study. Pain visual analog scale, tender points, Fibromyalgia Impact Questionnaire, and Beck Depression Inventory were evaluated. Age, body mass index (BMI), and symptom durations were also recorded. Native thiol, disulphide and total thiol levels were measured with a novel automated method. RESULTS: Serum disulphide levels were 14.7±3.4 µmol/L and 22.2±3.6 µmol/L in the FMS and control groups, respectively (p<0.001). Native thiol levels were 452.1±33.8 µmol/L and 433.5±37.6 µmol/L in the FMS and control groups, (p=0.015), while total thiol levels were 481.7±35.6 µmol/L and 477.5±38.9 µmol/L in the FMS and control groups, respectively (p=0.593). In the FMS group, disulphide/native thiol percent ratios and disulphide/ total thiol percent ratios were statistically significantly lower and native/total thiol percent ratios were statistically significantly higher than those of the control group. There were no correlations between serum thiol/disulphide profiles and pain scores & clinical variables in patients with FMS. CONCLUSION: Because of the decreased disulphide and increased native thiol levels, the thiol/disulphide balance has shifted to the reductive side. This metabolic disturbance may have a role in the pathogenesis of FMS.

Quality of life and correlation with musculoskeletal problems, hand disability and depression in patients with hemodialysis.

OBJECTIVES: The aims of this study were to assess the health-related quality of life (HRQOL) in patients with hemodialysis using the Kidney Disease Quality of Life (KDQOL™) and to determine its relationships with conventional clinical measures, musculoskeletal problems, hand disability and depression. MATERIALS AND METHODS: This study was conducted in our tertiary hospital's dialysis unit. Fifty patients under hemodialysis treatment were included in the study. HRQOL, disability, pain and depression were assessed using KDQOL-36, Duruoz hand index (DHI), visual analog scale (VAS) and Beck Depression Inventory (BDI). RESULTS: It was seen that all of the patients included had one or more musculoskeletal problems, the most common of which were muscle cramps, myalgias and arthralgias. Depression was the second most common accompanying disease. It was also seen that older patients had much poorer physical functioning scores, DHI scores and BDI scores than younger patients. DHI score was found to be significantly lower in men than in women. Educational level, presence of arthrosis, myalgia, bone pain, arthralgia, CTS, VAS-hand and VAS-upper extremities scales, DHI and BDI scores significantly affected both physical and mental areas of KDQOL-36, whereas age, shoulder periarthritis, mobilization scores and presence of hypertension only had effects on physical areas. CONCLUSION: Physical functioning depends mainly on the age, severity of comorbid conditions, depression, locomotor findings and hand disability of hemodialysis patients. The KDQOL-36 is related to the clinical status and functional ability of hemodialysis patients and it can be used as a sensitive health status measure for clinical evaluation.

Spinning-induced rhabdomyolysis: A case report and review of literature.

Rhabdomyolysis is a condition of skeletal muscle breakdown in which muscle injury causes a release of myoglobin and the muscle enzymes creatine phosphokinase (CPK), lactate dehydrogenase (LDH), and transaminases. Exertional rhabdomyolysis, which is precipitated by exercise or exertion, ranges from mild muscle injury with negligible symptoms or systemic effects to fulminant cases. Herein, we report a 26-year-old female patient who was admitted to our Physical Medicine and Rehabilitation outpatient clinics with severe bilateral thigh pain persisting for 5 days after participating in a spinning class and diagnosed with exertional rhabdomyolysis. Timely diagnosis and treatment prevented the potentially life-threatening consequences. We assume that it is essential to raise the awareness of this phenomenon not only by physicians but also by the community, since regular exercise and being physically active are increasingly encouraged in modern life.

Quality of life and self-reported disability in patients with knee osteoarthritis.

OBJECTIVES: Osteoarthritis (OA) is the most common degenerative joint disorder and a major public health problem throughout the world. The aims of this study are to assess quality of life (QoL) in patients with knee OA using the generic instrument Short Form-36 (SF-36) and to determine its relationships with conventional clinical measures and self-reported disability. METHODS: Patients with knee OA (n = 112) with median age of 60 (45-76) years and 40 sex- and age-matched healthy controls were included in the study. Age, sex, body mass index (BMI), symptom duration, and Kellgren-Lawrence scores were recorded. QoL, disability, and pain were assessed using the SF-36, the Western Ontario and McMaster (WOMAC) index, the Lequesne index, and a visual analog scale (VAS) in patients. Also, QoL was assessed using the SF-36 in controls. RESULTS: Patients with knee OA had lower scores in all subgroups of SF-36 compared with controls. In patients, the SF-36 physical function (PF) and pain areas significantly correlated with effusion, VAS pain, and Lequesne and WOMAC subgroup scores (p < 0.05). The pain area of QoL did not show correlation with comorbidity with knee OA. We found that SF-36 and WOMAC pain scores were more severe in female patients. CONCLUSIONS: Patients with knee OA had significantly poorer QoL compared with healthy controls. SF-36 is related to the clinical status and functional ability of patients with OA and can be used as a sensitive health status measure for clinical evaluation. Also WOMAC can be used as a sensitive measure for disability of patients with knee OA.

Fatigue and correlation with disease-specific variables, spinal mobility measures, and health-related quality of life in ankylosing spondylitis.

OBJECTIVES: This study aimed to evaluate fatigue in Turkish patients with ankylosing spondylitis (AS) and its relationship with disease-specific variables, spinal mobility measures, and health-related quality of life (HR-QoL). METHODS: One hundred and ten patients diagnosed as AS according to the Modified New York Criteria and 40 healthy individuals were included in this study. The Multidimensional Assessment of Fatigue (MAF) was used in patient and control groups to assess fatigue. The first item of Bath AS Disease Activity Index (BASDAI) was also used to assess fatigue in the patient group. Evaluation included BASDAI, functional status [BAS Functional Index (BASFI)], and visual analog scale (VAS) of axial and joint pain. Erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) were also measured. The generic instrument Short Form 36 (SF 36) was used to assess HR-QoL in the patient group. RESULTS: Patients with AS had higher total MAF scores and in all MAF subgroup scales than controls. All patient MAF scores were significantly correlated with morning stiffness, number of swollen joints, history of peripheral arthritis, BASDAI, BASFI, BASDAI-fatigue, VAS axial, VAS peripheral, and SF 36 subgroups (p < 0.05). No correlation was observed between all MAF scores and age, body mass index (BMI), disease duration, meteorological measures, and medications in patients. CONCLUSIONS: Patients with AS defined significantly more fatigue when compared with healthy persons. MAF was related to clinical and functional status and HR-QoL of patients with AS. We assume that MAF can be used as a sensitive fatigue measure in patients with AS.

Prevalence of atopic disorders in rheumatic diseases.

OBJECTIVES: The aim of this study was to assess the point prevalences of hay fever, asthma, and atopic dermatitis in OA, RA, and AS, and to compare with healthy controls. METHODS: A total of 935 patients and healthy controls were included. Demographic and clinical features were recorded, and a questionnaire assessing the existence of atopic disorders like asthma, hay fever, and atopic dermatitis in all groups was applied. "Either atopy" implied that an individual was either diagnosed with or had symptoms of one or more of these disorders, such as asthma, hay fever, or atopic dermatitis. RESULTS: When compared to the controls, only patients with AS had an increased risk for hay fever (OR 1.52, 95 % CI 1.00-2.41). Patients with RA had increased risks for hay fever, atopic dermatitis, and either atopy compared to the patients with OA (2.14, 95 % CI 1.18-3.89; 1.77, 95 % CI 1.00-3.18; and 3.45, 95 % CI 1.10-10.87, respectively). Steroid use had no effect on the prevalence of atopic disorders in patients with RA. CONCLUSIONS: Patients with OA, RA, and AS seem to have similar risks for asthma, atopic dermatitis, and either atopy to healthy controls. However, the prevalence of hay fever may increase in AS. Patients with RA have a higher risk of atopy than patients with OA.

Assessment of lumbar vertebrae morphology by magnetic resonance imaging in osteoporosis.

OBJECTIVE: To investigate the lumbar spinal morphology in patients with and without osteoporosis by comparing the endplate changes, intervertebral disc changes, and vertebral heights. DESIGN: This is a retrospective study. Medical records of the 3,530 patients admitted to the Physical Medicine and Rehabilitation outpatient clinics with low back pain between August 2010 and August 2011 were retrospectively reviewed. A total of 64 patients of whom 57 were females (89.1 %) and seven were males (10.9 %) were included in the study. Participants were divided into an osteoporosis group, an osteopenia group, and a nonosteoporotic control group, according to bone mineral densities. RESULTS: In this study, mid heights of L3, L4, and L5 vertebrae were found to be higher in the normal group than in both the osteopenic and osteoporotic groups. Mid part heights of L1-2, L2-3, and L5-S1 intervertebral discs were significantly lower in the normal group when compared to the osteopenic and osteoporotic groups. End-plate marrow abnormality was detected in L1 lower end plate in 75 % of normal subjects, 40.6 % of osteopenics, and 25 % of osteoporotics. Statistically significant difference in the presence of Schmorl nodes in L5 vertebra lower end plates was present between groups; 58.3 % of normals, 34.4 % of osteopenics and 15 % of osteoporotics had Schmorl nodes in L5 vertebra lower end plates. There was a significant difference regarding disc degeneration and intradiscal gas presence in L5-S1 intervertebral discs between groups; 66.7 % of normals, 28.1 % of osteopenics, and 25 % of osteoporotics had severe disc degeneration and intradiscal gas was present in L5-S1 intervertebral discs. CONCLUSIONS: Significant changes in morphology of the lumbar spine and intervertebral discs were found. It was revealed that the effects of osteoporosis are not limited to the bone but also present in the intervertebral discs. Mid heights of intervertebral discs were higher in the osteoporotic and osteopenic groups when compared to normal subjects along with the lowered mid heights of lumbar vertebrae. It was also observed that stronger vertebral bones were associated with more disc and vertebral degeneration.

Psychological status is associated with health related quality of life in patients with rheumatoid arthritis.

OBJECTIVE: Rheumatoid arthritis (RA) is a chronic and disabling disease frequently effects physical and psychological well being. The aim of the present study was to determine the impact of psychological status on health related quality of life in patients with RA and also to assess which quality of life (QoL) instrument - disease specific and generic - is more prone to this effect. METHODS: A total of 421 patients with RA recruited from joint database of five tertiary centers. Depression and anxiety risks were assessed by the Hospital Anxiety and Depression Scale (HADS); and quality of life assessed by Rheumatoid Arthritis Quality of Life (RAQoL), Nottingham Health Profile (NHP) and The Short Form 36 (SF 36) questionnaire. RESULTS: Patients with higher risk for depression or anxiety had poorer quality of life compared to the patients without risk for depression or anxiety. Depression and anxiety scores significantly correlated with quality of life questionnaires. There was significant association between anxiety and depression with worsening in both disease specific and generic health related quality of life. However, RAQoL showed more association with depression and anxiety levels. CONCLUSION: Higher depression and anxiety risks showed increased deterioration in quality of life. Compared to generic QoL scales, RAQoL scale, a disease specific QoL instrument, is much more influenced by depression and anxiety.

Relationship between psychological status and disease activity and quality of life in ankylosing spondylitis.

Our aim in this study was to compare the depression and anxiety risk in patients with AS and healthy controls and also to determine the relationship between disease activity, quality of life and psychological well-being. Two hundred and forty-three patients with ankylosing spondylitis (AS) and 118 age-, sex- and education-matched healthy controls were enroled into the study. Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), and Functional Index, and Metrology Index, Health Assessment Questionnaire for Spondyloarthropathies (HAQ-S), Hospital Anxiety and Depression Scale (HADS) including depression subscale (HADS-D) and anxiety subscale (HADS-A), Ankylosing Spondylitis Quality of Life (ASQoL) Scale, duration of morning stiffness, pain-visual analogue scale (VAS), patient and physician's global assessment of disease activity (100 mm VAS) were used to assess clinical and psychological status. Patients had similar HADS-D but higher HADS-A than healthy controls. Patients with high risk for depression and anxiety had higher scores in BASDAI, BASFI and also poorer scores in VAS pain, patient global assessment, physician global assessment, HAQ-S and ASQoL. There was a negative correlation of HADS-D and HADS-A scores with educational level of the patients. Higher scores in HADS-D and HADS-A indicated poorer functional outcome and quality of life. Multivariate logistic regression analysis revealed that the HADS-D (OR=6.84), HAQ-S (OR=1.76), VAS pain score (OR=1.03) and ESR (OR=1.02) were independent risk factors for higher anxiety scores whereas HADS-A (OR=1.36) and ASQoL (OR=1.24) were independent risk factors for higher depression scores. The psychological status had close interaction with disease activity and quality of life in patients with AS.

Discrimination ability of ASDAS estimating disease activity status in patients with ankylosing spondylitis.

OBJECTIVES: To investigate discrimination ability of the Assessment of Spondyloarthritis International Society (ASAS) endorsed disease activity score (ASDAS) versions evaluating low and high disease activity in an unselected group of patients with ankylosing spondylitis (AS). METHODS: Patients consecutively included into the joint database of five university hospitals were analyzed for low or high disease activity according to different criteria. Standardized mean differences (SMD) for two ASDAS versions were evaluated. RESULTS: The ASDAS versions (back pain, morning stiffness, patient global pain, pain/swelling of peripheral joints, plus either erythrocyte sedimentation rate or C-reactive protein) discriminated high and low disease activity in subgroups according to Bath Ankylosing Spondylitis Disease Activity Score (BASDAI) and ASAS remission/partial remission criteria. ASDAS versions were also not influenced by peripheral arthritis and correlated well with other outcome measurements and acute-phase reactants. The ASDAS versions performed better than patient-reported measures or acute-phase reactants discriminating high and low disease activity status. CONCLUSION: Both ASDAS versions, consisting of both patient-reported data and acute-phase reactants, performed well in discriminating low and high disease activity. Further longitudinal data may better estimate the usefulness of ASDAS to assess disease activity subgroups and treatment response.

Pattern of disease onset, diagnostic delay, and clinical features in juvenile onset and adult onset ankylosing spondylitis.

OBJECTIVE: To assess the frequency of juvenile onset ankylosing spondylitis (JOAS) in Turkish patients with AS and to compare with adult onset AS (AOAS) in a cross-sectional study design. METHODS: A total of 322 patients were recruited from the joint database of 5 university hospitals in eastern Turkey. RESULTS: Patients with JOAS (n = 43, 13.4%) had significantly longer diagnostic delay (9.21 vs 5.08 yrs), less severe axial involvement and more prevalent uveitis (OR 2.92, 95% CI 1.25-6.79), and peripheral involvement at onset (OR 3.25, 95% CI 1.51-6.98, adjusted for current age; and OR 2.26, 95% CI 1.07-4.76, adjusted for disease duration). Patients with AOAS had higher radiographic scores and more restricted clinimetrics but similar functional limitations and quality of life. CONCLUSION: JOAS and AOAS had distinctive courses and Turkish patients with AS had similar features compared to other Caucasian patient populations.

Bone loss in ankylosing spondylitis: does syndesmophyte formation have an influence on bone density changes?

OBJECTIVE: The aim of this study was to assess bone mineral density (BMD) using dual-energy X-ray absorptiometry (DXA) in a group of patients with ankylosing spondylitis (AS) and the factors which have an impact on bone mass. Also, a subgroup of patients not treated with anti-osteoporotic or disease-modifying anti-rheumatic drugs was followed for 24 months to assess potential influencing factors on BMD changes. SUBJECTS AND METHODS: Fifty-five patients (42 males, 13 females) with AS were enrolled in the study. Clinical examinations were performed. BMD was measured using DXA at lumbar spine (L2-L4) and proximal femur (femur neck BMD and total femur BMD). Lumbar spine radiographs were scored using the Stoke Ankylosing Spondylitis Spine Score (SASSS). Twenty-one of 55 patients who completed 24 months of follow-up without using the aforementioned medications were reassessed. RESULTS: Active patients (Bath Ankylosing Spondylitis Disease Activity Index >4, n = 22) had significantly lower femur neck and total BMD compared to inactive patients (n = 33), whereas spinal BMD was not different. Follow-up data revealed a 3.4% increase in spinal BMD but 0.9% and 0.25% decreases in femur neck BMD and total femur BMD, respectively. Percent changes in BMD measurements and SASSS scores were not significantly different between active (n = 10) and inactive (n = 11) patients. CONCLUSION: Significant increase in spinal BMD in parallel with increased SASSS revealed that spinal involvement prominent with new bone formation, sclerosis and syndesmophytes may influence spinal BMD measurements using DXA methods in AS. Proximal femur measurements seem to be less affected from disease-related new bone formation.

HLA-b27 subtypes in patients with spondylarthropathies, IgE levels against some allergens and their relationship to the disease parameters.

In suitable genetic backgrounds, some exogenous and/or endogenous antigens may cause SpA. In this study, we investigated HLA B27 subtypes and its relationship to some allergens and clinical findings in a group of SpA patients. Forty-eight patients (19F, 29M) with SpA (27 with ankylosing spondylitis, 5 with reactive arthritis, 15 undifferentiated and 1 with psoriatic arthritis) were included to the study. HLA-B alleles have been assessed using the LiPA (Line Probe Assay) reverse hybridization principle method. The allergens studied were following: egg white, yolk, wheat flour, hot pepper, tomatoes, olive, onion, chicken, black tea, sheep cheese, penicillin panel (m1, m25, m28, m30), fungus panel (m1, m2, m3, m6), and housemix panel (e1, e2, d1, d2, m2, m3). 59.3% of the patients were positive for HLA-B27. Of these patients, 53.6% had B*2702 allele which was the most common, followed by B*2708 (21.1%) and B*2701 (10.5%). HLA-B27 was positive in 70% of the ankylosing spondylitis patients and 52% had B*2702 subgroup and B35 was the most common subgroup among the patients who were HLA-B27 negative. Allergic reactions against these 13 allergens were more severe in patients HLA-B27 positive. The most frequent allergic reactions were against the onion and housemix panel, followed by red pepper, tomatoes, sheep cheese and olive. HLA-B*2702 and HLA-B*2701 subgroups had more severe allergic reactions that correlated with a disease severity (p < 0.001). These results indicate that B*2702 and B*2708 is more frequent in our region in contrast to B*2705 which is more commonly found all around the world and that our region represents a heterogeneous distribution. IgE levels against some allergen were found higher in patients with SpA (Fig. 2, Tab. 5, Ref. 37).

Direct current therapy with/without lidocaine iontophoresis in myofascial pain syndrome.

OBJECTIVES: This study aimed to assess the effectiveness of lidocaine iontophoresis for inactivation of trigger points (TrPs) in the treatment of myofascial pain syndrome (MPS). METHODS: Fifty-eight trigger points (cervical and/or periscapular regions) in 18 female and 2 male patients with MPS were randomly assigned to two groups. These groups were treated with: lidocaine iontophoresis using direct current (3 mA, 10 min) (n: 10, 28 TrPs) or only direct current (n: 10, 30 TrPs). Lidocaine iontophoresis or direct current, followed by stretching and strengthening exercises of each of the involved muscles and postural exercises were given in both groups once daily for ten days. Clinical assessment including cervical range of motion (ROM), TrP pain pressure threshold (PPT) measurement, and manual pain scores (PS), Visual analogue scale-pain (VAS-pain), fatigue and work disability scores were evaluated at baseline, at the end of a 10 session course of treatment and at the end of fourth week. Additionally, Hamilton depression and anxiety rating scales and Nottingham Health Profile (NHP) were used to evaluate and assess depression and anxiety and quality of life, respectively. The subjects were also asked to describe their side effects. RESULTS: PPT, pain scores, VAS-pain were significantly improved in both groups at the end of treatment and during evaluation at fourth week. The improvement of these parameters was not significantly different between groups at the end of treatment. Quality of life (NHP scores) (p<0.016) and depression and anxiety scores (p<0.05) significantly improved with treatment in both groups. CONCLUSION: Direct current therapy with/without lidocaine iontophoresis were determined to be effective treatment modalities in TrP management. These treatment modalities are non-invasive, cost effective and provide long term improvement. Thus, these modalities could be safely used in the management of MPS with minimal side effects, particularly if patients may not accept injection or other treatments (Tab. 3, Ref. 44).

Bone mineral density in patients with Parkinson's Disease.

BACKGROUND AND AIMS: This study assesses bone mineral density (BMD) in the lumbar spine, proximal femur and hand, and examines the relationship between BMD and disease duration, Hoehn and Yahr staging in Turkish elderly patients with Parkinson's disease (PD). DESIGN: Twenty-four PD patients and 31 age- and sex-matched controls took part in the study. The BMD in the lumbar spine (L2-L4), femoral neck, Ward's triangle, trochanter and bilateral hands were evaluated by dual X-ray absorptiometry (DXA). RESULTS: There was no significant difference in right hand BMD (rHBMD), L2-L4 spinal BMD, and right proximal femur BMD between patients and controls. However, in female patients hand BMD and right femoral neck BMD were significantly lower than in female controls (p<0.05). Male patients had no significant difference in BMD measurements in any sites compared with controls. Patients' Hoehn and Yahr index and disease duration were negatively correlated with BMD in all sites except L2-L4. CONCLUSIONS: We emphasize the increased risk for osteoporosis in elderly female patients with PD, which is more prominent in proximal femur and hand measurements. Elderly female patients should be carefully examined and screened for osteoporosis to prevent bone loss and associated disability.

Clinical evaluation and power Doppler sonography in rheumatoid arthritis: evidence for ongoing synovial inflammation in clinical remission.

OBJECTIVE: This study proposed to assess the relationship between power Doppler ultrasound examination and spectral Doppler analysis of hand joints with clinical and laboratory parameters in rheumatoid arthritis. METHODS: Patients receiving disease-modifying antirheumatic drugs or biologics (infliximab) underwent joint examination and were assessed by a Health Assessment Questionnaire, Duruoz's Hand Index, and Hand Function Test. All were categorized for disease activity using the American College of Rheumatology and disease activity score 28-joint (DAS28) criteria. Ten metacarpophalangeal joints and 4 wrist joints (ulnar-carpal and radiocarpal joints) in each patient were examined by power Doppler and spectral Doppler. Flow signal in the synovium was semiquantitatively graded. A cumulative flow signal score (CFS) and mean resistive index (RI) was calculated in each patient. RESULTS: Patients with active disease had significantly higher CFS compared with patients with inactive disease, but the mean RI was similar. Health Assessment Questionnaire, Duruoz's Hand Index, Larsen, and DAS28 scores correlated significantly with CFS, but the erythrocyte sedimentation rate and C-reactive protein scores did not. Mean RI did not correlate with clinical or laboratory parameters. A majority of patients who were in clinical remission according to American College of Rheumatology or DAS28 criteria had ongoing synovial inflammation on power Doppler ultrasound (58% and 62%, respectively). CONCLUSION: Power Doppler examination of rheumatoid hand joints is a practical method to estimate synovial inflammation. A modification of current remission criteria by combining imaging techniques with clinical and laboratory examination may be conceivable. These results underscore the necessity of more sophisticated research, assessing the agreement between long-term Doppler changes and clinical parameters.

Osteoporosis risk factors and association with somatotypes in males.

BACKGROUND: Osteoporosis is a systemic and metabolic skeletal disease characterized by reduced bone mass, changes in microarchitecture, and consequential increased fracture risk. Previous reports described a relationship between bone content with fat mass and lean body mass. In this study, we assessed osteoporosis risk factors and the association with somatotypes in males aged 45-65 years. METHODS: Standard axial spine and proximal femur bone mineral density (BMD) were measured using dual x-ray (DXA) absorptiometry in 70 healthy men. Heath-Carter procedure was followed to assess individual's somatotype. RESULTS: All body types were grouped as endomorphy, mesomorphy, and ectomorphy. Moderate to weak correlations were found between lumbar BMD with endomorphy and mesomorphy. Negative correlation was found between lumbar BMD and ectomorphy. Total femur BMD correlated positively with endomorphy and mesomorphy and negatively correlated with ectomorphy. Body mass index correlated weakly with lumbar, femur neck, and total femur BMD. Multiple regression analysis revealed that endomorphy was significantly related to BMD measurements at lumbar spine (standardized coefficient, SC = 0.51, p = 0.001), femur neck (SC = 0.52, p = 0.001), and total femur BMD (SC = 0.41, p = 0.01). Lumbar BMD and age, hand grip strength, smoking, tea and coffee consumption, calorie expenditure, calcium intake, PTH, albumin, total protein, sex hormone-binding globulin, and testosterone were not significantly correlated. CONCLUSIONS: Endomorphy seems related to high BMD values at the lumbar spine and the proximal femur in middle-aged men. Somatotype together with daily calorie expenditure may be taken into account when assessing risk factors for male osteoporosis.

Evaluation of a quantitative scoring of enthesitis in ankylosing spondylitis.

BACKGROUND: Enthesitis is inflammation at the insertion of ligaments, tendons, joint capsule, or fascia to bone, and a well-known characteristic feature of ankylosing spondylitis (AS) and related spondyloarthropathies. The clinical evaluation of enthesitis is an important outcome measure and is scored by applying pressure on entheses to elicit tenderness at these sites. OBJECTIVE: This study assessed the validity of an enthesitis index calculated by algometric pressure pain threshold scoring in comparison with digital palpation scoring and intra- and interexaminer reliability of 2 grading methods of the Maastricht Ankylosing Spondylitis Enthesitis Score (MASES). PATIENTS AND METHODS: Five hundred forty six entheses were examined in AS patients. Examination was performed on enthesopathy regions proposed by MASES. All of these entheses were examined by firm palpation with the thumb, and tenderness was graded on a 4-point scale. The summed tenderness scores were expressed as total palpation pain score (t-PS). After this procedure, the same entheses were rescored by using a mechanical algometer, and the sum was expressed as total pressure pain threshold (t-PPT). Fifteen indicators of functional, disease-activity, and anthropometric measures were used including global assessment of disease activity on a 0 to 100 mm visual analogue scale (global), Bath Ankylosing Spondylitis Disease Activity Index, Health Assessment Questionnaire-SpA, Dougados Functional and Articular Index, Bath Ankylosing Spondylitis Functional Index, ESR, CRP, occiput-to-wall distance, finger-to-floor distance, finger-to-fibula distance, chest expansion, and duration of morning stiffness in minutes. RESULTS: There was a significant correlation between clinical variables and t-PS and t-PPT, which was better for t-PS. Intraexaminer reliability was moderate to excellent for digital palpation scoring (intraclass correlation coefficients 0.55-0.96) and algometric scoring (0.54-0.96). Interexaminer reliability was fair to excellent for digital palpation scoring (0.43-0.84) and moderate to excellent (0.52-0.88) for algometric scoring. CONCLUSION: Our results indicate that algometric evaluation of entheses does not add extra information to clinical relevance of MASES, and grading with digital palpation is a more convenient, practical, and reliable examination method for the assessment of enthesitis.
