16245073 | Hypothesis: the humoral immune response to oral bacteria provides a stimulus for the devel | 2004 Dec | Rheumatoid arthritis (RA) and adult periodontitis share common pathogenetic mechanisms and immunologic and pathological findings. One oral pathogen strongly implicated in the pathogenesis of periodontal disease, Porphyromonas gingivalis, possesses a unique microbial enzyme, peptidylarginine deiminase (PAD), the human equivalent of which has been identified as a susceptibility factor for RA. We suggest that individuals predisposed to periodontal infection are exposed to antigens generated by PAD, with de-iminated fibrin as a likely candidate, which become systemic immunogens and lead to intraarticular inflammation. PAD engendered antigens lead to production of rheumatoid factor-containing immune complexes and provoke local inflammation, both in gingiva and synovium via Fc and C5a receptors. | |
15552516 | Longer term benefits of treating rheumatoid arthritis: assessment of radiographic damage a | 2004 Sep | Evidence from randomized controlled trials with newly approved DMARD therapies have proven efficacy by American College of Rheumatology [ACR] response criteria, Disease Activity Scores [DAS] and radiographic measures of disease progression. Treatment over 2 years duration results in clinically meaningful improvements in physical function, by the Health Assessment Questionnaire [HAQ] and health related quality of life [HRQOL], using the medical outcomes short form 36 [SF-36]. Changes in HAQ are evident within one month, maximal at 3-6 months, and sustained over 24 months, reflected by improvements in social functioning, role emotional and the general health profile as well as physical domains of SF-36. Trials with the new DMARDs, as well as MTX, indicate that long term benefits in radiographic damage and physical function can be inferred from treatment data over 12 months. "Successful" patients who continue to do well will derive benefit from treatment for as long as 3 to 5 years. Recent RCTs indicate that combination therapy, initiated together, offers more improvement in radiographic progression and physical function than monotherapy, although the trial data cannot yet tell us which DMARD may be most beneficial in a given patient. Once treatment with any one agent--biologic or synthetic--is initiated, the addition of a second agent should occur rapidly, if for example active disease persists 8 or 12 weeks later, without waiting for documented treatment failure. If this treatment paradigm is followed, along with regular assessments of radiographic damage and physical function, then patients may more likely derive long term clinical benefit than with traditional approaches. | |
15517302 | [Out-of-pocket medical spending for care in patients with recent onset rheumatoid arthriti | 2004 Oct | We examined out-of-pocket medical expenditures (OoP) of 869 patients with recent onset rheumatoid arthritis (ACR criteria, disease duration <2 years) using data from a prospective observational cohort. Out-of-pocket costs were retrospectively assessed for a period of 6 months by a list of 14 cost domains. Of the patients, 82% had costs due to copayments for prescribed drugs and 56% for over-the-counter drugs. Within six months each patient spent an average of 47 (+/- 67) Euro as co-payment and 45 (+/- 96) Euro for over-the-counter drugs. A comparable sum was spent for complementary and alternative medicine (47+/-250 Euro), which was used by 14% of the patients. The mean total OoP expenditure caused by RA was 628 Euro p.a. (median 306, IQ 66-334 Euro). The median costs accounted for approximately 2% of the average disposable yearly income in Germany. Out-of-pocket spending increased with functional limitations, poor health condition and pain as well as with level of education. A multivariate logistical regression analysis showed that patients with these characteristics spent about twice as much as patients with mild disease or low educational level. The odds ratios for having more than 306 Euro OoP-costs p.a. were OR=2.6 (CI 1.7-4) for patients with severe vs. moderate functional disability (HAQ> or =1.5 vs <1.5), OR=2.4 (CI 1.4-4.4) for patients in poor vs. good health condition (NRS 7-10 vs 0-3), and OR=2.1 for patients with severe vs. mild pain (CI 1.4-3.3). The level of OoP spending also varied by employment status (OR=0.28; CI 0.1-0.6 for jobless vs employed patients). Despite almost universal insurance coverage in Germany, patients with rheumatoid arthritis were exposed to substantial OoP expenditures. As policymakers discuss cost sharing and design of benefit packages to contain health spending, it is important to consider the expenditures that persons with chronic conditions like rheumatoid arthritis already have. | |
14673962 | Management of depression in rheumatoid arthritis: a combined pharmacologic and cognitive-b | 2003 Dec 15 | OBJECTIVE: To examine the effectiveness of cognitive-behavioral and pharmacologic treatment of depression in rheumatoid arthritis (RA). METHODS: Subjects (n = 54) with confirmed diagnoses of both major depression and RA were randomly assigned to 1 of 3 groups: 1) cognitive-behavioral/pharmacologic group (CB-PHARM), 2) attention-control/pharmacologic group, or 3) pharmacologic control group. Measures of depression, psychosocial status, health status, pain, and disease activity were collected at baseline, posttreatment (10 weeks), 6-month followup, and 15-month followup. Data were analyzed to compare the treatment effectiveness of the groups; data also were aggregated to examine the effects of antidepressive medication over time. Lastly, a no-treatment control group was defined from a cohort of persons who declined participation. RESULTS: Baseline comparisons on demographic and dependent measures revealed a need to assess covariates on age and education; baseline scores on dependent measures also were entered as covariates. Analyses of covariance revealed no statistically significant group differences at postintervention, 6-month followup, or 15-month followup, except higher state and trait anxiety scores for the CB-PHARM group at the 15-month followup. In the longitudinal analyses of the effects of antidepressive medication, significant improvement in psychological status and health status were found at posttreatment, 6-month followup, and 15-month followup, but no significant improvements were shown for pain or disease activity. In addition, the comparison of the aggregated pharmacologic group with a no-treatment group revealed a statistically significant benefit for the 3 groups that received the antidepressive medication. CONCLUSION: In persons with RA, cognitive-behavioral approaches to the management of depression were not found to be additive to antidepressant medication alone, but antidepressant intervention was superior to no treatment. | |
15103249 | Ultrasonography in rheumatoid arthritis: a very promising method still needing more valida | 2004 May | PURPOSE OF REVIEW: Through recent technological advances, ultrasonography allows high-resolution visualization of inflammatory and destructive changes in the small superficial joints of hands and feet, and ultrasonography is increasingly used by rheumatologists for assessment of rheumatoid arthritis patients. It is, therefore, highly relevant to consider the validity of ultrasonographic measures of rheumatoid joint inflammation and damage. RECENT FINDINGS: Organized by type of validity, data on ultrasonography in rheumatoid arthritis are reviewed. Encouraging reports of high agreement of ultrasonographic findings between observers, with MRI and, in knee and hip joints, histopathologic assessments were recently published. New quantitative and semiquantitative evaluation methods have been suggested, and the first systematic follow-up studies suggest an ability of ultrasonography to monitor joint inflammation and damage. However, a number of essential issues are still largely unexplored, including interscanner variability, sensitivity to change, prognostic value, and value in the diagnosis of rheumatoid arthritis. Suggested areas of priority in research and development of ultrasonography in rheumatoid arthritis are outlined. SUMMARY: Ultrasonography is a very promising method in the assessment of rheumatoid arthritis joints, but still needs more validation before it can take up its expected role on a scientific basis as an important tool for diagnosis, monitoring, and prognostication of patients with rheumatoid arthritis and suspected rheumatoid arthritis. | |
11895349 | Radiolunate arthrodesis in the rheumatoid wrist: a retrospective clinical and radiological | 2002 Feb | A retrospective study was performed to investigate the clinical and radiological results of radiolunate arthrodesis in the rheumatoid wrist. Ninety-one wrists in 78 patients were assessed at a mean follow-up of 60 months. Most patients were pain-free and content with the overall result. In 68 wrists the carpus had been repositioned or maintained in neutral or slightly ulnar alignment and no further translation occurred. Midcarpal dislocation occured in ten and midcarpal rotation in 13 wrists. The midcarpal joint underwent further arthritic destruction in 34 wrists and secondary arthrosis in 32 wrists. In 25 wrists the midcarpal joint space remained unchanged. Radiolunate arthrodesis can successfully be performed in wrists even with advanced destruction. In cases with fixed carpal collapse, anatomical repositioning of the lunate and restoration of carpal height should not be attempted as this causes midcarpal dislocation or rotation or precipitates secondary arthrosis. | |
15334431 | Impact of social support on valued activity disability and depressive symptoms in patients | 2004 Aug 15 | OBJECTIVE: To examine the impact of instrumental and emotional support on valued life activity (VLA) disability and depressive symptoms. Instrumental support was expected to affect VLA disability; emotional support was expected to be associated with depressive symptoms and moderate the impact of VLA disability on depressive symptoms. METHODS: Data were collected over 3 years through interviews with the University of California, San Francisco, Rheumatoid Arthritis Panel. Analyses assessed whether instrumental support predicted later VLA disability and whether emotional support predicted both concurrent and later depressive symptoms. RESULTS: Receiving adequate instrumental support was associated with less subsequent VLA disability. Strong associations were noted between both VLA disability and emotional support with concurrent depressive symptoms. No relationship was found between emotional support and later depression. No evidence was found for the hypothesis that emotional support moderated the impact of VLA disability on depressive symptoms. CONCLUSION: Results highlight the need to assess different types of support and their unique impact on critical outcomes. Instrumental support is beneficial to the maintenance of valued activities, a critical factor in the psychological adjustment of individuals living with rheumatoid arthritis. Emotional support has a significant short-term impact on depression, although it may not buffer the impact of VLA disability on future depression. | |
15638046 | 169Erbium-citrate synoviorthesis after failure of local corticosteroid injections to treat | 2004 Nov | OBJECTIVES: Intra-articular injection of 169Erbium-citrate (169Er-citrate; radiosynoviorthesis or radiosynovectomy) is an effective local treatment of rheumatic joint diseases. However, its efficacy in corticosteroid-resistant rheumatoid arthritis-affected joints has not been clearly demonstrated. METHODS: A double-blind, randomised, placebo-controlled, international multicentre study was conducted in patients with rheumatoid arthritis with recent (< or = 24 months) ineffective corticosteroid injection(s) into their finger joint(s). Eighty-five finger joints of 44 patients were randomised to receive a single injection of placebo (NaCl 0.9%) or 169Er-citrate. Results of evaluation 6 months later were available for 82 joints (46 metacarpophalangeal and 36 proximal interphalangeal joints) of 42 patients: 39 169Er-citrate-injected joints and 43 placebo-injected joints. Efficacy was assessed using a rating scale for joint pain, swelling and mobility. RESULTS: Intent-to-treat analysis of the results of the 82 joints showed a significant effect of 169Er-citrate compared to placebo for the principal criteria decreased pain or swelling (95 vs 79%; p = 0.038) and decreased pain and swelling (79 vs 47%; p = 0.0024) and for the secondary criteria decreased pain (92 vs 72%; p = 0.017), decreased swelling (82 vs 53%; p = 0.0065) and increased mobility (64 vs 42%; p = 0.036). Per-protocol analysis, excluding 18 joints of patients who markedly changed their usual systemic treatment for arthritis, gave similar percentages of improvement but statistical significance was lower owing the reduced power of the statistical tests. CONCLUSION: These results confirm the clinical efficacy of 169Er-citrate synoviorthesis of rheumatoid arthritis-diseased finger joints after recent failure of intra-articular corticotherapy. | |
15366666 | Arthroscopic treatment of rheumatoid synovitis. | 2003 | Arthroscopic synovectomy (AS) as a therapeutic modality in the treatment of chronic rheumatoid synovitis of the knee joint refractory to disease-modifying anti-rheumatic drugs (DMARDs) still enjoys an unflagging interest. Synovectomy has a lasting beneficial effect on the local manifestations of the rheumatoid inflammation. The purpose of the study was to evaluate the long-term results of arthroscopic synovectomy of knee joint combined with tidal lavage in patients with chronic rheumatoid synovitis included in a 5-year prospective study. METHODS: 84 patients (13 men, 71 women, mean age 45.3 +/- 14.7 yrs) with rheumatoid arthritis (RA) received a partial arthroscopic synovectomy. The diagnosis was made according to the criteria of the American College of Rheumatology (ACR) (1987). All patients received active treatment with DMARDs for at least 3 months prior to the arthroscopic synovectomy. Local treatment with corticosteroids was also administered without any lasting effect. The synovectomy was performed under local anesthesia with motorized shaver and followed by tidal lavage with 6-8 liters of saline solution. All synovectomies were performed by one and the same team of rheumatologists. The result of the synovectomy was assessed using the Knee Assessment Questionnaire (KAQ8); the patients' functional status was assessed by mHAQ20 and Disability mHAQ04. RESULTS: After the AS there was a significant improvement in the KAQ8 indices: pain relief, improvement of the knee joint function, reduction of the symptoms of local joint lesion and of the parameters of self-care restriction. This beneficial effect held throughout all 60 months of follow up and only started to weaken at the end of this period. The mHAQ20 scores after AS remained significantly lower even 60 months after AS, and the Disability mHAQ04 scores remained on the level before AS. These results indicate the presence of beneficial effect from AS on the general functional status and the parameters of disability of patients studied. CONCLUSION: Arthroscopic synovectomy combined with tidal lavage of the knee joint is a major therapeutic modality in the treatment of chronic synovitis in RA. Arthroscopic synovectomy of the knee joint significantly and for a long period of time relieves pain in the operated joint, improves the joint function, reduces the symptoms of the local joint lesion, decreases general disability and improves the capacity for self care. | |
15262104 | Effect of a treatment strategy of tight control for rheumatoid arthritis (the TICORA study | 2004 Jul 17 | BACKGROUND: Present treatment strategies for rheumatoid arthritis include use of disease-modifying antirheumatic drugs, but a minority of patients achieve a good response. We aimed to test the hypothesis that an improved outcome can be achieved by employing a strategy of intensive outpatient management of patients with rheumatoid arthritis--for sustained, tight control of disease activity--compared with routine outpatient care. METHODS: We designed a single-blind, randomised controlled trial in two teaching hospitals. We screened 183 patients for inclusion. 111 were randomly allocated either intensive management or routine care. Primary outcome measures were mean fall in disease activity score and proportion of patients with a good response (defined as a disease activity score <2.4 and a fall in this score from baseline by >1.2). Analysis was by intention-to-treat. FINDINGS: One patient withdrew after randomisation and seven dropped out during the study. Mean fall in disease activity score was greater in the intensive group than in the routine group (-3.5 vs -1.9, difference 1.6 [95% CI 1.1-2.1], p<0.0001). Compared with routine care, patients treated intensively were more likely to have a good response (definition, 45/55 [82%] vs 24/55 [44%], odds ratio 5.8 [95% CI 2.4-13.9], p<0.0001) or be in remission (disease activity score <1.6; 36/55 [65%] vs 9/55 [16%], 9.7 [3.9-23.9], p<0.0001). Three patients assigned routine care and one allocated intensive management died during the study; none was judged attributable to treatment. INTERPRETATION: A strategy of intensive outpatient management of rheumatoid arthritis substantially improves disease activity, radiographic disease progression, physical function, and quality of life at no additional cost. | |
12649702 | [Hidden bone erosions]. | 2003 | The aim of this pictorial essay was to demonstrate the diagnostic efficacy of high-resolution sonography in detecting bone erosions in a patient with rheumatoid arthritis. Standard X-Ray of the feet did not reveal clearly evident erosions. Ultrasonography was able to detect the presence of bone erosions of the metatarsal heads of both the first toes and of the V toe of the left foot. Because the appearance of bone erosions on radiographs of a patient with a recent onset arthritis indicates a poor prognosis, the possibility of demonstrating small hidden erosions at the level of the early targets of the disease is of relevant practical value. | |
14641545 | Geographic patterns of functional categories of HLA-DRB1 alleles: a new approach to analys | 2003 Oct | Because specific amino acids found within the peptide-binding cleft of human leukocyte antigen (HLA) molecules have been implicated in HLA/disease associations, an approach which consists in grouping the alleles according to their functional properties at the protein level may enable us to better understand HLA associations than the conventional allelic classification. In this study, we applied this methodology to investigate the associations between HLA-DRB1 and rheumatoid arthritis. The alleles were first classified into seven functional categories [restrictive supertype patterns (RSPs)], among which three were known to be significantly associated with susceptibility (one category) or resistance (two categories) to rheumatoid arthritis. The frequencies of these categories were then estimated in 104 population samples previously tested for HLA-DRB1, and their variability was analysed spatially on a worldwide scale by applying an original methodology for detecting discontinuities in geographically patterned data. RSP frequencies were also compared to known values of rheumatoid arthritis prevalence in some populations. The results indicated that the three RSP frequency distributions were geographically structured, and that these patterns could generally be explained by the history of human migrations. However, the peculiar pattern observed for RSP 'A' (conferring susceptibility to rheumatoid arthritis) indicated a possible association with some latitude-dependent disease. Furthermore, the very high correlation coefficient found between RSP 'A' frequencies and rheumatoid arthritis prevalence confirmed the significant disease association of this functional category. In contrast, the putative protective effect of the other RSPs ('De' and 'Q') was not detectable at the worldwide level, but may be significant in specific geographic areas. This study shows that population genetic diversity analyses based on a functional grouping of HLA alleles provide an efficient way to explore the mutual influence of HLA genetic variation and disease. | |
12110146 | Epidemiology and genetics of rheumatoid arthritis. | 2002 | The prevalence of rheumatoid arthritis (RA) is relatively constant in many populations, at 0.5-1.0%. However, a high prevalence of RA has been reported in the Pima Indians (5.3%) and in the Chippewa Indians (6.8%). In contrast, low occurrences have been reported in populations from China and Japan. These data support a genetic role in disease risk. Studies have so far shown that the familial recurrence risk in RA is small compared with other autoimmune diseases. The main genetic risk factor of RA is the HLA DRB1 alleles, and this has consistently been shown in many populations throughout the world. The strongest susceptibility factor so far has been the HLA DRB1*0404 allele. Tumour necrosis factor alleles have also been linked with RA. However, it is estimated that these genes can explain only 50% of the genetic effect. A number of other non-MHC genes have thus been investigated and linked with RA (e.g. corticotrophin releasing hormone, oestrogen synthase, IFN-gamma and other cytokines). Environmental factors have also been studied in relation to RA. Female sex hormones may play a protective role in RA; for example, the use of the oral contraceptive pill and pregnancy are both associated with a decreased risk. However, the postpartum period has been highlighted as a risk period for the development of RA. Furthermore, breastfeeding after a first pregnancy poses the greatest risk. Exposure to infection may act as a trigger for RA, and a number of agents have been implicated (e.g. Epstein-Barr virus, parvovirus and some bacteria such as Proteus and Mycoplasma). However, the epidemiological data so far are inconclusive. There has recently been renewed interest in the link between cigarette smoking and RA, and the data presented so far are consistent with and suggestive of an increased risk. | |
15376571 | [Total knee arthroplasty in patients with rheumatoid arthritis]. | 2004 Mar | BACKGROUND: Approximately 90% of patients with rheumatoid arthritis (RA) will have one or both knees involved during the course of the disease. Total knee arthroplasty (TKA) allows restoring function and relieving pain satisfactorily, but these patients perform in a different way than those with primary knee osteoarthritis. AIM: To evaluate the clinical and radiographic results of TKA in patients with RA. PATIENTS AND METHODS: We analyzed retrospectively the data of 25 posterior stabilized total knee prostheses in 19 patients, available to an average follow-up of 6 years. The scores of Hospital for Special Surgery and of the Knee Society were used for clinical assessment. RESULTS: The mean Hospital for Special Surgery score increased from 44 points (range 27-58) preoperatively to 80 points (range 58-91) at the final follow-up examination. Two prostheses required revision and removal of the implants because of deep infection, and two had clinical failure as defined by the Knee Society score. There were no cases of implant loosening. DISCUSSION: Even though it is not free of complications, TKA is a good choice in patients with RA in the medium term follow up, with 80% of excellent and good results in our series. | |
12626793 | Long-term efficacy of a cognitive behavioural treatment from a randomized controlled trial | 2003 Mar | OBJECTIVES: This study examined the long-term efficacy of a cognitive behavioural intervention for patients with recent-onset, seropositive rheumatoid arthritis (RA). METHODS: Fifty-three consecutive patients with less than a 2-yr history of classic or definite RA were recruited into the trial. All participants received routine medical management during the study, and half were randomly allocated to receive an 8-week adjunctive psychological intervention. All assessments were conducted blind to the allocation. This paper reports intention-to-treat analyses of the 18-month follow-up. RESULTS: Consistent with short-term results, significant differences were found between the groups in depressive symptoms. The intervention group maintained improvements in joint function, although those in routine care made similar improvements over the ensuing 18 months. At follow-up, group differences emerged for disability and anxiety. CONCLUSIONS: These results indicate that cognitive behavioural intervention offered as an adjunct to standard clinical management early in the course of RA is efficacious in producing improvements in both psychological and physical indices. Furthermore, improvements appear to increase 18 months after a brief, time-limited psychological treatment. | |
12109033 | [Diagnosis of initial changes in the hand of patients with rheumatoid arthritis--compariso | 2002 Jun | Besides conventional X-rays, in the diagnostic work up of initial changes in patients suffering from rheumatoid arthritis (RA), 3-phase bone scintigraphy (3P-Sz) is as well established as magnetic resonance imaging (MRI). The aim of this study was to compare the diagnostic value of the newly developed low field MRI with the proven methods X-rays and 3P-Sz. METHODS: 65 patients (47f, 18m; 20-86 yrs) were studied on a one day protocol with 3P-Sz (550 MBq Tc-99m DPD), MRI and X-rays of the hands. Images were visually analysed by two blinded nuclear medicine physicians and radiologists and classified as a) RA-typical, b) inflammatory, non-RA-typical and c) non inflammatory changes. All methods were compared to 3P-Sz as golden standard. RESULTS: In comparison to 3P-Sz, low field MRI presents with almost equal sensitivity and specificity in rheumatoid-typical and inflammatory changes. Conventional X-rays revealed in arthritis-typical changes as well as in inflammatory changes a significantly lower sensitivity and also a lower negative predictive value while specificity equals the one of MRI. Quantitative analysis of 3P-Sz using ROI-technique unveiled significantly higher values in patients with rheumatoid arthritis than in those with no inflammatory changes. CONCLUSION: MRI represents an equally sensitive method in the initial diagnosis of rheumatoid-typical and inflammatory changes in the region of the hands as compared to the 3P-Sz. Besides the basic diagnosis with conventional X-rays, 3P-Sz is still the recommended method of choice to evaluate the whole body when RA is suspected. Additionally, quantitative analysis of the 3P-Sz using the ROI technique in the region of the hands reveals statistically significant results and should therefore be taken into account in the assessment of inflammatory changes. | |
15372845 | The effects of age, seropositivity and disease duration on autonomic cardiovascular reflex | 2004 Aug | Previous studies have shown that autonomic cardiovascular reflexes (ACRs) are impaired in rheumatoid arthritis (RA) and in old age. To investigate the integrity of ACRs in patients with RA, with reference to age, duration of disease and rheumatoid factor (RF) positivity, we conducted a prospective open study of 62 RA outpatients (age 38-84) and 41 healthy controls (age 22-82) using five standard tests of ACR function. Patients of all ages with RA were found to have blunted ACRs when compared with younger controls, though this effect was subclinical. Older RA patients did not have significantly more ACR impairment than older controls. There was a tendency to greater impairment of ACRs in RA patients with a positive RF. The age-associated changes in ACRs in normal subjects are similar to those seen in RA patients of all ages. The effects of RA and age on ACRs do not appear to be additive. | |
15194577 | Determinants of direct costs in Dutch rheumatoid arthritis patients. | 2004 Jul | OBJECTIVES: To estimate annual direct costs in four distinct disease duration groups (0 to < or =2, 2 to < or =6, 6 to < or =10, and >10 years) of patients with rheumatoid arthritis (RA), to determine predictors of high costs and to describe characteristics of patients with high and with low costs. METHODS: A questionnaire assessing RA related care and resource utilisation rates and costs was completed by 615 RA patients. Predictive variables for incurred costs, as observed during the first year after disease onset, were determined in a subgroup of patients (n = 347). RESULTS: Mean (median) annual direct costs for the four groups with increasing disease duration were respectively: 5235 (2923) Euros, 3930 (1968) Euros, 4664 (1952)Euros, and 8243 (3778) Euros, (p < 0.05). During the first 2 years of the disease total direct costs comprised mainly of consultations with healthcare workers (28%). After 10 years, devices and adaptations were the main contributors (40%) to total costs. Positive rheumatoid factor results at the time of diagnosis and deterioration of functional disability in the first year of disease were predictors of high costs later on in the course of the disease. CONCLUSION: Annual direct costs among patients with a disease duration of less than 2 years tend to be lower among patients with a disease duration of between 2 and 10 years than among patients with a disease duration of more than 10 years. In addition, the proportional distribution of different cost categories to total costs increases with with increasing disease duration. | |
11803304 | Memory for pain: the relationship of pain catastrophizing to the recall of daily rheumatoi | 2002 Jan | OBJECTIVE: The assumption that individuals are capable of accurately recalling past painful experiences has been a fundamental tenet of a number of cognitive-behavioral theories of pain, including the gate control theory. However, there has been very little research on the topic in the past, and the results have often been contradictory. A general conclusion that can be drawn is that memory for pain is variable, and there is need to identify what factors contribute to this variability in memory for pain. The current study examined the relation of catastrophizing to the recall of persistent pain associated with rheumatoid arthritis. METHODS: Participants in this study were 45 individuals with persistent pain due to rheumatoid arthritis. Each participant was asked to complete a daily pain diary for a period of 30 days. Participants were subsequently asked to recall the pain they experienced over the entire period of time rather than provide a single, average rating. RESULTS: The results of a series of hierarchical regression analyses indicated that level of catastrophizing was related to the recall of both pain intensity and pain variability. This relation was statistically significant even after controlling for actual pain and variability and other background variables. CONCLUSIONS: Participants who scored higher on catastrophizing demonstrated better accuracy in the recall of general pain intensity and pattern over a 30-day diary period. The results of the study are discussed in terms of future studies as well as their potential clinical importance. | |
14730190 | A case report of unilateral hypoglossal neuroparalysis resulting from horizontal subluxati | 2003 Sep | We experienced a case of unilateral hypoglossal neuroparalysis, in which the right hypoglossal nerve was compressed by horizontal subluxation in the atlanto-occipital joint, due to rheumatoid arthritis. This report represents a very rare case of unilateral hypoglossal neuroparalysis, in which diagnostic imaging of CT with multiple cross-sectional images (three-dimensional CT) was quite useful for the identification of compression by horizontal subluxation. |
