Evaluation of 25(OH) vitamin D3 and quadriceps strength correlation in postmenopausal women: A cross-sectional study.

BACKGROUND: Vitamin D deficiency is common in postmenopausal women and is associated with low vitamin D intake, increased age, decreased absorption. Especially at advanced age, vitamin D deficiency may increase muscle weakness and disbalance resulting in increased risk of fracture. OBJECTIVES: This study aims to explore the correlation between 25(OH) vitamin D3 levels and quadriceps muscle strength in postmenopausal women. METHODS: We evaluated bilateral qadriceps muscle strength in postmenopausal women with isokinetic test. We evaluated the correlation of muscle power with measurements of parathormone, vitamin D, Calcium, creatinine, alanine transaminase, alkaline phosphatase, total creatine kinase. RESULTS: The mean vitamin D level of 95 participants included in the study was 18.24 ± 8.94 ng/ml. Vitamin D levels were found to be deficient (< 10 ng/ml) in 23 (24.1%), insufficient in 62 (65.26%) and normal in 10 (10.53%) of the 95 participants. A weak negative correlation was observed between participants' vitamin D levels and PT values (r=-0.271, p= 0.012). A moderate negative correlation was found between ALP and vitamin D levels (r=-0.317, p= 0.002). However, there was no significant correlation between vitamin D levels and the 60∘ and 90∘ flexion and extension peak torque values (All p values > 0.05). CONCLUSIONS: Vitamin D levels and muscle strength weren't statistically significant. Few studies are available in the related literature, highlighting the need for further research to achieve a clearer consensus.

Correlation of clinical signs and magnetic resonance imaging findings in patients with lumbar spondylosis.

Objectives: The purpose of the study was to contribute further to this debated topic by investigating the correlation of magnetic resonance imaging (MRI) findings with the clinical picture in lumbar spondylosis patients. Patients and methods: This multicenter retrospective study (as part of the epidemiological project of the TLAR-OASG [Turkish League Against Rheumatism-Osteoarthritis Study Group]) included 514 patients (101 males, 413 females; mean age: 63.6±10.8 years; range, 40 to 85 years) who were diagnosed as lumbar spondylosis by clinical examination and direct X-ray between December 2016 and June 2018. Demographic characteristics of patients, Visual Analog Scale for pain, presence of radiating pain, Roland-Morris disability questionnaire, straight leg raise test, deep tendon reflexes, neurogenic intermittent claudication symptoms, any decrease of muscle strength, and abnormality of sensation were recorded. Lumbar MRI findings of the patients were recorded as positive or negative in terms of disc herniation, intervertebral disc degeneration, root compression, osteophytes, spinal stenosis. Statistical analysis was done to assess the correlation between the clinical symptoms, physical examination, and MRI findings. Results: Correlation analysis of the MRI results and the clinical findings showed a significant correlation between straight leg raise test and root compression (p<0.001, r=0.328) and a significant correlation between neurogenic intermittent claudication and spinal stenosis (p<0.001, r=0.376). Roland-Morris disability questionnaire had a significant correlation with all MRI findings (p<0.05, r<0.200). Conclusion: The results of this study corroborate the notion that diligent patient history and physical examination are more valuable than MRI findings, even though a higher incidence of abnormal MRI findings have been obtained in patients with disability and dermatomal radiating pain.

Anti-mutated citrulline vimentin antibodies may be higher in Ankylosing spondylitis, but may not have a role in diagnosing disease and may not be associated with disease severity.

OBJECTIVE: Ankylosing spondylitis (AS) is a rheumatologic disease with severe morbidity and mortality. Many studies in the literature showing that serum antibodies against anti-mutated citrullinated vimentin (anti-MCV ab) can be elevated in rheumatoid arthritis (RA) patients. However, there is little data in the literature about the levels of anti-MCV antibodies in AS patients. We designed the study to evaluate the role of anti-MCV antibody in the diagnosis of AS and to investigate whether it is associated with disease activity parameters. METHODS: There were three separate groups in our study. The number of participants in these groups is 60 patients in the AS group, 60 patients in the RA group, and 50 healthy participants in the control group. The anti-MCV ab levels of the participants were measured by enzyme-like immune assay method. We compared anti-MCV levels between groups. We then evaluated its role in the diagnosis of AS and evaluated its relationship with disease activity parameters. RESULTS: The anti-MCV antibody levels of both AS (p=0.006) and RA (p>0.001) patients were found to be significantly higher than controls. Anti-MCV antibody was higher than predefined threshold level (20 IU/mL) in 4 of 60 (6.7%) AS patients. Anti-MCV levels are similar in patients with or without a -acceptable symptom state (PASS). There is also no appropriate anti-MCV cutoff level with respect to PASS and a highly sensitive and specific level for diagnosis of AS. CONCLUSION: Although AS patients has higher anti-MCV levels than controls, it may have a limited ability to AS diagnosis and to predict severity of the disease.

Evaluating the relationship between ankylosing spondylitis and periodontal disease: a case-control study.

OBJECTIVES: This study aimed to determine the possible relationship between periodontal disease and ankylosing spondylitis (AS) by evaluating clinical periodontal measurements and gingival crevicular fluid (GCF) levels of sclerostin, interleukin-1ß (IL-1ß), and matrix metalloproteinase-8 (MMP-8) levels. MATERIALS AND METHODS: Twenty-eight patients with AS (AS group) and 28 systemically healthy controls (C group) were enrolled in this study. Full-mouth periodontal measurements: plaque index, bleeding on probing (BOP), probing pocket depth (PPD), and clinical attachment level (CAL) measurements were obtained from all patients. AS-related parameters were included in the data analyses. An enzyme-linked immunosorbent assay determined GCF IL-1ß, MMP-8, and sclerostin levels. RESULTS: There were no significant differences in the clinical periodontal measurements between the two groups (p > 0.05). Interestingly, patients with AS had significantly lower GCF sclerostin levels than the C group (p < 0.05). But there were no statistical differences in the GCF levels of IL-1ß and MMP-8 between the two groups (p > 0.05). Serum C-reactive protein (CRP) levels strongly correlated with both BOP (r = 0.497, p < 0.05) and PPD (r = 0.570, p < 0.05) in the AS group. Bath AS Metrology Index (BASMI) also positively correlated with both BOP (r = 0.530, p < 0.05) and CAL (r = 0.568, p < 0.05). Similarly, Maastricht Ankylosing Spondylitis Enthesis Score (MASES) strongly correlated with both BOP (r = 0.487, p < 0.05) and CAL (r = 0.522, p < 0.05). CONCLUSION: These results suggest that the patient's systemic condition may influence local sclerostin levels in GCF, and the strong correlations between periodontal measurements and AS-related parameters may indicate an interrelationship between inflammatory periodontal disease and AS. CLINICAL RELEVANCE: The present study provides important information concerning the relationship between periodontal disease and ankylosing spondylitis.

B cell depletion in patients with rheumatoid arthritis is associated with reduced IL-1ß in GCF.

OBJECTIVES: We evaluated the effect of B cell depletion on the clinical periodontal findings and IL-1ß and MMP-8 levels of the gingival crevicular (GCF) fluid in patients with rheumatoid arthritis (RA). MATERIALS AND METHODS: Seventy patients were included in this case-control study. Twenty patients with RA were undergoing B-cell depletion treatment. The second group of RA patients (n = 20) were undergoing non-B-cell depletion treatment with Disease-Modifying Anti-Rheumatic Drugs (DMARD). Control group, with no RA, consisted of 30 individuals. Periodontal parameters including probing depth (PD), clinical attachment level (CAL), bleeding on probing (BOP), gingival index (GI), and plaque index (PI) were recorded. IL-1ß and MMP-8 levels in GCF were determined using enzyme-linked immunosorbent assay. Rheumatological parameters including Disease Activity Score-28 (DAS-28), rheumatoid factor levels (RF), and anti-cyclic citrullinated peptide levels were included in the data analyses. RESULTS: All groups were similar in PD, CAL, BOP, GI, and PI measures. GCF IL-1ß levels were 1.85 ± 1.67 pg in the B-cell depletion group, 10.50 ± 13.16 pg in the DMARD group, and 34.12 ± 29.45 pg in the control group (p < 0.001). MMP-8 levels were 21.00 ± 4.23 pg in the B-cell depletion group, 8.16 ± 6.94 pg in the DMARD group, and 21.45 ± 8.67 pg in the control group (p < 0.001). DAS 28, RF, and anti-CCP were similar in RA groups. CONCLUSIONS: GCF IL-1ß levels were significantly lower in B cell depletion group, and MMP-8 levels were significantly lower in DMARD group, suggesting that rheumatoid arthritis treatments may modify biochemical parameters of GCF. CLINICAL RELEVANCE: This study suggests that host modulation therapies in RA can reduce local production of IL-1ß and MMP-8. Reduction of these inflammatory cytokines and enzymes may have a beneficial effect in controlling periodontal tissue destruction.

The clinical, functional, and radiological features of hand osteoarthritis: TLAR-osteoarthritis multi-center cohort study.

Objectives: This study aims to evaluate the clinical, functional, and radiological features of hand osteoarthritis (OA) and to examine their relationships in different geographic samples of the Turkish population. Patients and methods: Between April 2017 and January 2019, a total of 520 patients (49 males, 471 females; mean age: 63.6±9.8 years) with hand OA were included in the study from 26 centers across Turkey by the Turkish League Against Rheumatism (TLAR). The demographic characteristics, grip strengths with Jamar dynamometer, duration of hand pain (month), the severity of hand pain (Visual Analog Scale [VAS]), and morning stiffness were evaluated. The functional disability was evaluated with Duruöz Hand Index (DHI). The Kellgren-Lawrence (KL) OA scoring system was used to assess the radiological stage of hand OA. Results: The DHI had significant correlations with VAS-pain (r=0.367, p<0.001), duration of pain (r=0.143, p=0.001) and bilateral handgrip strengths (r=-0.228, p=0.001; r=-0.303, p<0.001). Although DHI scores were similar between the groups in terms of the presence of hand deformity (p=0.125) or Heberden's nodes (p=0.640), the mean DHI scores were significantly higher in patients with Bouchard's nodes (p=0.015). The total number of nodes had no significant correlations with the VAS-pain and DHI score (p>0.05). The differences between the groups of radiological hand OA grades in terms of age (p=0.007), VAS-pain (p<0.001), duration of pain (p<0.001), and DHI (p<0.001) were significant. There were no significant differences between radiological hand OA grades according to the duration of the stiffness, grip strength, and BMI (p>0.05 for all). Conclusion: In our population, the patients with hand OA had pain, functional disability, and weak grip strength. The functional impairment was significantly correlated with the severity of the pain, and the functional status was worse in high radiological hand OA grades.

Relationship between periodontal status and disease activity in patients with ankylosing spondylitis.

OBJECTIVES: Ankylosing spondylitis (AS) is a chronic inflammatory disease mainly affecting the spine and sacroiliac joints, characterized by enthesitis. Recent studies have investigated the relationship between AS and periodontitis. The aim of this study was to evaluate the periodontal status of patients with AS and to determine the factors affecting this. MATERIAL AND METHODS: The study included 200 AS patients, of which 129 were taking anti-tumour necrosis factor (TNF) drugs and 71 were taking non-steroid anti-inflammatory drugs (NSAID). Patients did not change their medication during the study. Disease activity was evaluated with the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), mobility with the Bath Ankylosing Spondylitis Metrology Index (BASMI), functional status with the Bath Ankylosing Spondylitis Functional Index (BASFI), enthesitis with the integrated Maastricht Ankylosing Spondylitis Enthesitis Score (MASES), and quality of life with the Ankylosing Spondylitis Quality of Life (ASQoL) scale. Data related to erythrocyte sedimentation rate, and C-reactive protein were recorded from the hospital information system. The plaque index (PI), gingival index (GI), pocket depth (PD), attachment level (CAL) measurements, and bleeding index (BOP) were measured. RESULTS: The results showed that 35.5% of the AS patients had periodontitis, at a lower rate in the anti-TNF group than in the NSAID group, but the difference was not statistically significant. Periodontitis-related factors were found to be age, BASFI and BASMI. A significant relationship was found between MASES and BOP and GI. CONCLUSIONS: This suggests that periodontitis may be an enthesis in AS. Nevertheless, further studies are needed to explain the mechanism of periodontitis in AS patients.

Prednisolone-Induced Hairy Tongue: A Case Report.

Hairy tongue is a benign and mostly asymptomatic disorder characterized by elongation of papillae with typical hairy-like appearance on the dorsal surface of the tongue. Many medical conditions, antibiotics, and drugs inducing xerostomia are associated with hairy tongue. In this article, we report a female patient with polymyalgia rheumatica who developed hairy tongue following treatment with prednisolone. Clinicians should be aware of the predisposing factors and drugs that may have a role in the development of hairy tongue.

Accelerated Nodulosis in a Patient With Rheumatoid Arthritis.

In patients with rheumatoid arthritis (RA), subcutaneous nodules are the most frequently seen extra-articular findings that are seen in areas of extensor pressure. In this article, we present the case of a RA patient with accelerated nodulosis that started with the use of methotrexate and exacerbated with etanercept and leflunomide treatment.

Can the Second to Fourth Digit Ratio (2D : 4D) Be a Marker to Determine Ankylosing Spondylitis Disease Activity?

OBJECTIVE: The length ratio of the index finger (2D) to the ring finger (4D) (2D : 4D ratio) is considered a biomarker of prenatal sex hormone exposure. The 2D : 4D ratio is influenced by prenatal androgen and estrogen levels. Because ankylosing spondylitis (AS) influences men more frequently and severely than women, androgens are proposed to be related to AS pathogenesis. Estrogens have immune-modulating effects and reduce AS disease activity. The aim of this study was to assess the relationship between 2D : 4D ratio and AS disease activity. MATERIAL AND METHODS: In this study, 167 (43 female) patients diagnosed with AS were studied. The lengths of the second and fourth fingers were measured using a digital caliper. The 2D : 4D ratio was found by dividing the length of the second finger by the length of the fourth finger. AS disease activity was assessed with the Turkish version of the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI). AS functional status was assessed with Bath Ankylosing Spondylitis Functional Index (BASFI). L-Schober, tragus to wall distance, finger to floor distance, and chest expansion were used to evaluate mobility. RESULTS: In female patients, the right hand 2D : 4D ratios were higher than those in male patients. Biologic drug use was more frequent in males. The BASDAI scores were higher in female patients than in male patients. There were significant negative correlations between right and left hand 2D : 4D ratio and BASFI and BASDAI in female patients. There was no significant correlation between the 2D : 4D ratio and BASFI or BASDAI in male patients. We found a positive correlation between L-Schober and right hand 2D : 4D and a negative correlation between the left hand 2D : 4D ratio and finger to floor distance in female patients with AS. CONCLUSION: The 2D : 4D ratio of the right and left hand was low in female patients with high BASFI and BASDAI and low spinal mobility (L-Schober) was also linked to low female 2D : 4D. The lack of strong associations between 2D : 4D and AS in male patients may have resulted from their higher use of biologics.

Coexistence of ankylosing spondylitis and discoid lupus: A case report.

Coexistence of ankylosing spondylitis with connective tissue diseases is very rare. Here, in this study, we describe a coexistence of ankylosing spondylitis and discoid lupus erythematosus in a 35-year-old man. He presented with a 5-year history of low back pain and concurrent development of a discoid rash. Inflammatory low back pain, HLA-B27 positivity and bilateral active sacroiliitis confirmed the diagnosis of ankylosing spondylitis. Discoid lupus erythematosus was diagnosed based on a skin biopsy. There are reports of discoid lupus associated with medications, particularly with tumour necrosis factor-alpha (TNF-α) blocking drugs. However, the patient presented here had coexistence of ankylosing spondylitis and discoid lupus before starting such treatments.

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.

Management of Psoriatic Arthritis: Turkish League Against Rheumatism (TLAR) Expert Opinions.

OBJECTIVES: This study aims to establish the first national treatment recommendations by the Turkish League Against Rheumatism (TLAR) for psoriatic arthritis (PsA) based on the current evidence. PATIENTS AND METHODS: A systematic literature review was performed regarding the management of PsA. The TLAR expert committee consisted of 13 rheumatologists and 12 physical medicine and rehabilitation specialists experienced in the treatment and care of patients with PsA from 22 centers. The TLAR recommendations were built on those of European League Against Rheumatism (EULAR) 2015. Levels of evidence and agreement were determined. RESULTS: Recommendations included five overarching principles and 13 recommendations covering therapies for PsA, particularly focusing on musculoskeletal involvement. Level of agreement was greater than eight for each item. CONCLUSION: This is the first paper that summarizes the recommendations of TLAR as regards the treatment of PsA. We believe that this paper provides Turkish physicians dealing with PsA patients a practical guide in their routine clinical practice.

Turkish League Against Rheumatism Consensus Report: Recommendations For Management of Axial Spondyloarthritis.

OBJECTIVES: This study aims to update 2011 Turkish League Against Rheumatism SpondyloArthritis Recommendations, and to compose a national expert opinion on management of axial spondyloArthritis under guidance of current guidelines, and implantation and dissemination of these international guidelines into our clinical practice. PATIENTS AND METHODS: A scientific committee of 28 experts consisting of 14 rheumatologists and 14 physical medicine and rehabilitation specialists (one of them also has an immunology PhD) was formed. The recommendations, systematic reviews, and meta-analyses including pharmacologic and non-pharmacologic treatment were scrutinized paying special attention with convenient key words. The draft of Turkish League Against Rheumatism opinion whose roof consisted of international treatment recommendations, particularly the Assessment of SpondyloArthritis International Society/European League Against Rheumatism recommendations was composed. Assessment of level of agreement with opinions by task force members was established through the Delphi technique. Voting using a numerical rating scale assessed the strength of each recommendation. RESULTS: Panel compromised on five basic principles and 13 recommendations including pharmacological and nonpharmacological methods. All of the recommendations had adequate strength. CONCLUSION: Turkish League Against Rheumatism expert opinion for the management of axial spondyloArthritis was developed based on scientific evidence. These recommendations will be updated regularly in accordance with current developments.

2017 update of the Turkish League Against Rheumatism (TLAR) evidence-based recommendations for the management of knee osteoarthritis.

In a Turkish League Against Rheumatism (TLAR) project, evidence-based recommendations for the management of knee osteoarthritis (OA) was developed for the first time in our country in 2012 (TLAR-2012). In accordance with developing medical knowledge and scientific evidence, recommendations were updated. The committee was composed of 22 physical medicine and rehabilitation specialists (4 have rheumatology subspeciality also) and an orthopaedic surgeon. Systematic literature search were applied on Pubmed, Embase, Cochrane and Turkish Medical Index for the dates between January the 1st 2012 and January the 29th of 2015. The articles were assessed for quality and classified according to hierarchy for the level of evidence, and the selected ones sent to committee members electronically. They were asked to develop new recommendations. In the meeting in 2015, the format of the recommendations was decided to be patient-based and considering the grade and the severity of the disease. By the discussion of the each item under the light of new evidences, the final recommendations were developed. Each item was voted electronically on a 10-cm visual analogue scale (VAS) and the strength of recommendation (SoR) was calculated. In the light of evidences, totally 11 titles of recommendations were developed; the first 7 were applicable to each patient in every stages of the disease, remaining were for defined specific clinical situations. The mean SoR value of the recommendations was between 7.44 and 9.93. TLAR-2012 recommendations were updated in a new format. We think that, present recommendations will be beneficial for the physicians who manage, as well as the patients who suffer from the disease.

Turkish League Against Rheumatism (TLAR) Recommendations for the Pharmacological Management of Rheumatoid Arthritis: 2018 Update Under Guidance of Current Recommendations.

OBJECTIVES: This study aims to report the assessment of the Turkish League Against Rheumatism (TLAR) expert panel on the compliance and adaptation of the European League Against Rheumatism (EULAR) 2016 recommendations for the management of rheumatoid arthritis (RA) in Turkey. PATIENTS AND METHODS: The EULAR 2016 recommendations for the treatment of RA were voted by 27 specialists experienced in this field with regard to participation rate for each recommendation and significance of items. Afterwards, each recommendation was brought forward for discussion and any alteration gaining ≥70% approval was accepted. Also, Turkish version of each item was rearranged. Last version of the recommendations was then revoted to determine the level of agreement. Levels of agreement of the two voting rounds were compared with Wilcoxon signed-rank test. In case of significant difference, the item with higher level of agreement was accepted. In case of no difference, the changed item was selected. RESULTS: Four overarching principles and 12 recommendations were assessed among which three overarching principles and one recommendation were changed. The changed overarching principles emphasized the importance of physical medicine and rehabilitation specialists as well as rheumatologists for the care of RA patients in Turkey. An alteration was made in the eighth recommendation on treatment of active RA patients with unfavorable prognostic indicators after failure of three conventional disease modifying anti-rheumatic drugs. Remaining principles were accepted as the same although some alterations were suggested but could not find adequate support to reach significance. CONCLUSION: Expert opinion of the TLAR for the treatment of RA was composed for practices in Turkish rheumatology and/or physical medicine and rehabilitation clinics.

Oxidases and oxygenases in regulation of neutrophil redox pathways in Behçet's disease patients.

This study aimed to determine plasma and neutrophil oxidase activities that may contribute to vascular inflammation in Behçet's disease (BD) patients. Cyclooxygenase (COX), NADPH oxidase and myeloperoxidase (MPO) activity was determined in neutrophils isolated from BD patients and healthy controls. Functional assay of NADPH oxidase was significantly increased in BD patients, both at basal conditions and in response to fMLP stimulation. There was a significant increase in plasma MPO activity in the disease group as compared to controls. Total COX activity was significantly increased in BD neutrophils. The increase in total COX activity was accompanied with enhanced activity of COX-2, differentiated by using the COX-1 isoform-specific inhibitor SC-560. Neutrophil nitrate/nitrite levels showed no significant difference in BD; however, plasma nitrate/nitrite contents in BD patients were significantly greater compared to controls. In conclusion, increased plasma MPO, neutrophil NADPH and COX activities may contribute to intravascular inflammation documented in BD patients.

Which is the dominant factor for perception of rheumatic pain: meteorology or psychology?

It is believed that there is an association between the weather and rheumatic symptoms. We aimed to investigate what kind of association is present and what are the factors which determine the nature of this association. Fifty-six subjects with rheumatic disease (31 RA, 15 SpA, 10 OA) who live in Antalya were followed between December 2005 and July 2006. Patients were asked to fill diaries which contain questions regarding the symptoms of their rheumatic diseases everyday. In every monthly visit, disease activity measurement, laboratory assessment and Beck depression inventory assessment were recorded. The symptomatic and psychological measurements were matched with the meteorological data of Antalya Regional Directorate of Meteorological Service of Turkish State. Correlation of symptoms with weather variables was investigated. Contributory effect of weather and of psychologic factors on symptom scores were evaluated by stepwise multiple regression analysis. Eighty-four percent of subjects belive in an association between weather and rheumatism, while 57% claimed to have ability to forecast weather. The maximum correlation coefficient between weather and arthritis symptoms was -0.451 and the maximum contribution of weather on symptoms was 17.1%. Arthritis symptoms were significantly contributed by Beck depression score. The belief about presence of weather-arthritis association was found to be stronger than its statistical power. Our results did not prove or rule out the presence of weather-rheumatism association. As long as the scientific attempts result in failure, the intuitive support in favour of the presence of weather-arthritis association will go on forever.

The Agreement Between Blood Pool - Delayed Bone Scintigraphy and Tc-99m Human Immunoglobulin G (HIG) Scintigraphy in the Determination of the Presence and Severity of Inflammatory Arthritis.

OBJECTIVE: In this study, it was aimed to investigate the agreement between early phase of bone scintigraphy - human immunoglobulin scintigraphy (EPBS-HIG) and late phase bone scintigraphy - HIG (LPBS-HIG) in the determination of the presence and also the severity of inflammatory arthritis. MATERIAL AND METHODS: Twenty-eight patients (23 female, 5 male; between 19 to 80 years of age) with inflammatory arthritis were included in the study. Tc-99m HIG and blood pool/late phase bone scintigraphies were performed in all patients. In scintigraphic examinations, the joints were scored with the degree of accumulation of the radiopharmaceutical by the semiquantitative analysis (0=Background activity, 1=Faint uptake, 2=Moderate uptake, 3=Marked uptake) which is called as visually active joint score as severity index of the disease. To estimate the agreement between EPBS - HIG and LPBS - HIG in the determination of the presence and severity of inflammatory arthritis, 2x2 kappa coefficients were calculated. RESULTS: Our results showed good agreement between EPBS - HIG for the presence of inflammation (kappa: 0.72) but not for the severity of the disease (kappa: 0.29), poor agreement between LPBS - HIG for both the presence (kappa: 0.51) and severity (kappa: 0.01) of inflammatory arthritis. CONCLUSION: The blood pool scintigraphy could be used in the investigation of the presence of inflammatory arthritis because the good agreement with HIG and the lower cost but not for the severity of the disease Conflict of interest:None declared.
