Abstract
OBJECTIVES The aim is to assess the prevalence of comorbidities and to further analyse to which degree fatigue can be explained by comorbidity burden, disease activity, disability and gross domestic product (GDP) in patients with rheumatoid arthritis (RA). METHODS Nine thousands eight hundred seventy-four patients from 34 countries, 16 with high GDP (>24.000 US dollars [USD] per capita) and 18 low-GDP countries (<24.000 USD) participated in the Quantitative Standard monitoring of Patients with RA (QUEST-RA) study. The prevalence of 31 comorbid conditions, fatigue (0-10 cm visual analogue scale [VAS] [10=worst]), disease activity in 28 joints (DAS28), and physical disability (Health Assessment Questionnaire score [HAQ]) were assessed. Univariate and multivariate linear regression analyses were performed to assess the association between fatigue and comorbidities, disease activity, disability and GDP. RESULTS Overall, patients reported a median of 2 comorbid conditions of which hypertension (31.5%), osteoporosis (17.6%), osteoarthritis (15.5%) and hyperlipidaemia (14.2%) were the most prevalent. The majority of comorbidities were more common in high-GDP countries. The median fatigue score was 4.4 (4.8 in low-GDP countries and 3.8 in high-GDP countries, p<0.001). In low-GDP countries 25.4% of the patients had a high level of fatigue (>6.6) compared with 23.0% in high-GDP countries (p<0.001). In univariate analysis, fatigue increased with increasing number of comorbidities, disease activity and disability in both high- and low-GDP countries. In multivariate analysis of all countries, these 3 variables explained 29.4% of the variability, whereas GDP was not significant. CONCLUSIONS Fatigue is a widespread problem associated with high comorbidity burden, disease activity and disability regardless of GDP.

Abstract
OBJECTIVES To describe the incidence and nature of bloodstream infections (BSI) among children with juvenile idiopathic arthritis (JIA) followed-up prospectively from disease onset. METHODS The Social Insurance Institution's (SII) national register on individuals with reimbursement for medication of chronic diseases was used to identify children with JIA from 2004 through 2011 and their medications. The National Infectious Disease Register (NIDR) collects data of all blood culture positive samples from all microbiology laboratories in Finland. We combined the NIDR and SII registers to identify JIA patients with BSI. Clinical and laboratory data of each JIA-BSI patient were collected from hospital records. RESULTS There were 1604 JIA patients and 6630 person-years of follow-up. Five patients had BSI. During the first 5 years after diagnosis the cumulative emergence of BSI was 0.38% [95% confidence interval (CI) 0.16% to 0.92%]. The incidence rates were 7.5/10 000 follow-up years for JIA (95% CI 2.4-17.6) and 2.8/10 000 follow-up years for the age-matched general population (95% CI 2.7-2.9). The standardised incidence ratio was 3.0 (95% CI 1.2 to 7.2). The causative bacteria were Streptococcus pneumoniae, Staphylococcus aureus, Escherichia coli and Fusobacterium necrophorum. Three patients were on anti-rheumatic drugs, including two on TNF inhibitors. All patients responded rapidly to antimicrobial therapy and recovered uneventfully. CONCLUSIONS Although BSI is rare among children with JIA, the incidence is 3-fold higher than among the general population.

Abstract
OBJECTIVES To evaluate the prevalence of levothyroxine-treated hypothyroidism in rheumatoid arthritis (RA) patients at the time of RA diagnosis in comparison to age- and sex-specific general population. Other objectives were to determine whether the risk of hypothyroidism varies by age at the onset of RA, or by sex or rheumatoid factor (RF) status. METHODS We identified 7,209 incident RA patients diagnosed between January 2004 and December 2007 from a Finnish nationwide register of special reimbursements for medication costs. The presence of hypothyroidism at RA diagnosis was identified from the same register based on special reimbursement decisions for levothyroxine substitution. The prevalence of levothyroxine-treated hypothyroidism was compared to that of an age- and sex-specific Finnish population, and a standardised rate ratio (SRR) for hypothyroidism was calculated. RESULTS The SRR for levothyroxine-treated hypothyroidism preceding RA was 1.51 (95% CI 1.35 to 1.67). Neither RF status nor sex modified the risk, although the results did not reach statistical significance among men. The SRR was highest, almost 2.5 among younger female RA patients (20-49 years of age), the excess prevalence of hypothyroidism decreasing steadily and wearing off among patients who were older at the time of diagnosis. The absolute prevalence of hypothyroidism, however, increased with age as it does in the general population. CONCLUSIONS The risk of hypothyroidism is increased among RA patients already at the disease onset, especially among the young women, regardless of RF status. This calls for attention to screening for hypothyroidism in RA patients, preferably when RA has already been diagnosed.

Abstract
Only limited evidence exists on the therapeutic potential of biologic agents in the treatment of myositis. We present a brief review of the literature on off-label experiences of biologic agents in myositis, with a special interest in abatacept. Rituximab has been indicated to be beneficial and well tolerated in one large randomized controlled trial and many smaller studies. Initial data on tumour necrosis factor (TNF) inhibitors are conflicting. There are only a few case reports and mechanistic studies on the treatment of myositis with other biologics, including alemtuzumab, anakinra, tocilizumab and abatacept. We report a patient with severe myositis overlap syndrome, manifesting also as rheumatoid arthritis, peripheral vasculitis and interstitial lung disease. Her myositis was refractory to many conventional and biologic therapies but was well controlled with abatacept. This suggests that abatacept might be a beneficial option for the treatment of refractory myositis and that clinical trials are needed to further investigate its efficacy.

Abstract
BACKGROUND AND PURPOSE Drug-based treatment of rheumatoid arthritis (RA) has evolved markedly over the past 2 decades. Using nationwide register data, we studied how this has affected the rates of hip, knee, shoulder, and elbow replacement from 1995 to 2010. METHODS The number of primary joint replacements was obtained from the Finnish Arthroplasty Register. To test the hypothesis that improvements in medical treatment of RA reduce the need for joint replacements, we also collected data about purchases of different disease-modifying anti-rheumatic agents (DMARDs) and biological drugs from the nationwide drug registers. RESULTS The annual incidence of primary joint replacements for RA declined from 19 per 10(5) in 1995 to 11 per 10(5) in 2010. The decline was greater for upper-limb operations than for lower-limb operations. At the same time, the numbers of individuals using methotrexate, hydroxychloroquine, and sulfasalazine (the most commonly used DMARDs) increased 2- to 4-fold. INTERPRETATION Our results are in accordance with observations from other countries, and indicate that the use of joint replacements in RA has decreased dramatically. Our data suggest that effective medical therapy is the most likely explanation for this favorable development.

Abstract
OBJECTIVES To assess the prevalence of coronary heart disease (CHD) and chronic hypertension among patients with rheumatoid arthritis (RA) at the time of diagnosis, in comparison with age-specific and sex-specific non-RA subjects. Furthermore, the impacts of age at the onset of RA, as well as gender and the presence of rheumatoid factor (RF) on the risk of these comorbidities, were evaluated. METHODS A cohort of 7209 RA patients diagnosed between January 2004 and December 2007 was identified, based on a Finnish nationwide register on special reimbursements for medication costs. The presence of CHD and chronic hypertension antedating the diagnosis of RA was identified from the same register. The prevalence of the cardiovascular comorbidities was compared with the general Finnish population, and a standardised rate ratio (SRR) for both these cardiovascular diseases was calculated. RESULTS The risk of having CHD at RA diagnosis was slightly elevated, the SRR being 1.10 (95% CI 1.01 to 1.20). Younger age at the onset of RA seemed to be related with higher SRR for CHD. In a subset analysis, an increased prevalence of hypertension (SRR 1.19, 95% CI 1.10 to 1.30) and CHD (SRR 1.15, 95% CI 1.00 to 1.32) was apparent only among the RF negative RA cases. CONCLUSIONS The SRR for CHD is augmented in RA patients already at disease onset, and more pronouncedly in early onset RA. The findings highlight the importance of early prevention of atherosclerosis, regardless of RF status.

Abstract
OBJECTIVE Early treatment of patients with rheumatoid arthritis (RA) with combination treatment starting with methotrexate, sulfasalazine, hydroxychloroquine and prednisolone (FIN-RACo strategy) is superior to monotherapy. A study was undertaken to determine whether infliximab (INFL) added to intensified FIN-RACo treatment for the initial 6 months improves the 2-year outcome. METHODS 99 patients with early untreated active RA were enrolled in an investigator-initiated, randomised, double-blind, multicentre, parallel-group trial. Primary outcomes were remission and radiological changes at 2 years. All patients started with FIN-RACo. In addition, they were randomised to receive INFL or placebo (Pla) from weeks 4 to 26. RESULTS At 24 months, 66% and 53%, respectively, of the patients in the FIN-RACo+INFL and FIN-RACo+Pla groups were in remission according to the modified American College of Rheumatology (ACR) criteria (p=0.19), 26% and 10% were in sustained modified ACR remission (p=0.042) and 82% in both groups were in remission by 28-joint disease activity score (not significant). Mean changes in the total Sharp-van der Heijde score were 0.2 and 1.4, respectively (p=0.0058). CONCLUSIONS Most patients with early active RA achieve clinical remission and develop negligible joint damage with the intensified FIN-RACo regimen. Adding INFL for the first 6 months delays radiological progression.

Abstract
The first patient entered the Rheumatism Foundation Hospital, Heinola, Finland in July 1951. From that point on, the hospital helped patients suffering from rheumatic disorders. Specialists in the hospital actively developed treatments and published a large number of scientific articles in international journals. The hospital was well known internationally among people working in the field. Progress in the development of disease-modifying medication (biological agents in particular) has dramatically improved the life of patients with rheumatic diseases, but all effective treatments may also have adverse effects. In this article, we briefly review the history of the Rheumatism Foundation Hospital, which was closed permanently in March 2010 due to bankruptcy. The economical difficulties were caused primarily by the progress made in disease-modifying therapy, which decreased the need of rehabilitation and operative treatment of patients with rheumatic diseases. It seems that a great success in biological agents can carry "serious adverse effects", which may kill hospitals. This is an important primary observation, which should be noticed when the future of specialised institutes is planned.

Abstract
OBJECTIVE The aim of this study was to assess the cost-utility and value of reducing the uncertainty associated with the decision to use first-line biologic treatment (bDMARD) after the failure of one or more traditional drugs (tDMARD) in moderate-to-severe rheumatoid arthritis (msRA) in Finland. RESEARCH DESIGN AND METHODS The treatment sequences were compared among 3000 hypothetical Finnish msRA patients using a probabilistic microsimulation model in a lifetime scenario. Adalimumab + methotrexate, etanercept + methotrexate, or tocilizumab + methotrexate were used as first biologics followed by rituximab + methotrexate and infliximab + methotrexate. Best supportive care (BSC), including tDMARDs, was assumed to be used after the exhaustion of the biologics. Methotrexate alone was added as a further comparator. Efficacy was based on ACR responses that were obtained from a mixed treatment comparison. The resources were valued with Finnish unit costs (year 2010) from the healthcare payer perspective. Additional analyses were carried out, including productivity losses. The Health Assessment Questionnaire (HAQ) values were mapped to the EQ-5D values using the tocilizumab trials; 3% annual discounting for costs and quality-adjusted life years (QALY) and extensive sensitivity analyses were completed. MAIN OUTCOME MEASURES Incremental cost per QALY gained and multinomial expected value of perfect information (mEVPI). RESULTS bDMARDs significantly increase the QALYs gained when compared to methotrexate alone. Tocilizumab + methotrexate was more cost-effective than adalimumab + methotrexate or etanercept + methotrexate in comparison with methotrexate alone, and adalimumab + methotrexate was dominated by etanercept + methotraxate. A QALY gained with retail-priced (wholesale-priced) tocilizumab + methotrexate costs €18,957 (€17,057) compared to methotrexate alone. According to the cost-effectiveness efficiency frontier and cost-effectiveness acceptability frontier (CEAF), tocilizumab + methotrexate should be considered before rituximab + methotrexate, infliximab + methotrexate, and BSC. Based on the CEAF, tocilizumab + methotrexate had a 60-93% probability of being cost-effective with €20,000 per QALY gained (mEVPI €230-2182). CONCLUSIONS Tocilizumab + methotrexate is a potentially cost-effective bDMARD treatment for msRA, indicating a low value of additional research information with the international threshold values. LIMITATIONS Efficacy based on an indirect comparison (certolizumab pegol, golimumab excluded), fixed treatment sequence after the exhaustion of first bDMARD, Swedish resource use data according to HAQ scores, and inpatient costs assumed to include surgery.

Abstract
OBJECTIVE To determine the prevalence of dry eye symptoms and signs in children with juvenile idiopathic arthritis (JIA). PATIENTS AND METHODS A total of 192 children with JIA: 48 oligo-, 39 extended oligo-, 79 polyarthritis, and 26 with other types of arthritis (eight juvenile spondyloarthritis, five juvenile psoriatic arthritis, three mixed connective tissue diseases, two systemic onset arthritis, and eight undetermined arthritis) were interviewed for dry eye symptoms and tested with Schirmer test with anesthetic. Two thirds of the patients were female and the mean age of the patients was 13.1 years (range 10-16) and the mean duration of arthritis was six years (SD 4, 4). Thirty-one percent of the patients had a history of uveitis. Dry eye was defined as Schirmer test score </= 5 mm in five minutes. The type of arthritis, a history of uveitis, and the ocular and systemic medication used were evaluated for their correlation with dry eye symptoms and signs by using chi-square tests and the Mann-Whitney Monte Carlo analysis. RESULTS Altogether 17% of this cohort had decreased basal tear secretion. The most common symptoms of dry eye were discharge secretion, itching, and watering. The intensity of symptoms and signs did not correlate. The type of arthritis, a history or presence of uveitis, and the medication used did not correlate with the occurrence of dry eyes. CONCLUSION Dry eye symptoms and signs are common in JIA, and Schirmer test with anesthetic is a useful tool in evaluating these patients.

Abstract
OBJECTIVE Our aim was to evaluate how frequently problems of quality and quantity of sleep and depression occur in patients with fibromyalgia (FM), and compare these findings with those occurring in patients with rheumatoid arthritis (RA) and in the general population. MATERIALS AND METHODS The patients were recruited from rehabilitation courses in the Rheumatism Foundation Hospital, Finland. There were 37 patients with FM and 31 patients with RA participating in the study. For comparison, we used the results from a general population study of 1284 adult subjects. The data had been collected earlier in a longitudinal cohort study for the Finnish Social Insurance Institution. RESULTS The patients with FM and RA slept fewer hours a day than the population sample. The FM patients reported more insomnia, less contentment with sleep and more lack of deep and restful sleep in comparison to the RA patients and the participants of the population study. The FM patients also reported significantly more depression and pain than the RA patients (p0.01). It was still shown in a logistic regression analysis that insomnia was almost five times more frequent in FM patients than in RA patients, even when depression and pain were adjusted. CONCLUSION The FM patients reported more insomnia-related symptoms than either RA patients or the population sample. The higher prevalence of insomnia-related symptoms among FM patients was not explained by depression or pain. Both patient groups reported somewhat shorter nocturnal sleep than the general population.

Abstract
OBJECTIVE To measure the presence of autoantibodies binding to intact human recombinant collagen IX and assess their usefulness as a diagnostic marker and an indicator of disease activity in rheumatoid arthritis (RA). METHODS Recombinant human full-length collagen IX (rCIX) was produced in a baculovirus expression system and purified for use in ELISA developed to detect antibodies to native and denatured collagen IX. Fifty-three patients with recent-onset rheumatoid factor-seropositive RA were analyzed for the presence of rCIX antibodies of the IgG type at the time of initial diagnosis and after 3, 6, 12, and 24 months of followup. The RA sera were accompanied by 30 controls. Associations were determined between patients' antibody titers, development of erosions in the hands and feet, and various clinical and laboratory markers. RESULTS Serum antibody levels among patients with RA at time of diagnosis were 1.78 times higher against native rCIX (p < 0.001) and 1.71 times higher against denatured rCIX (p < 0.001) than in the controls, and they remained high during the followup. No correlation was seen between antibody levels and clinical and laboratory findings. CONCLUSION Our data show that patients with recent-onset RA have significantly elevated levels of autoantibodies to human rCIX. These autoantibodies were observed already at the early stages of the disease, which may reflect their diagnostic potential in RA.

Abstract
OBJECTIVE To compare the functional ability of patients with spondyloarthropathy (SpA) and fibromyalgia (FM) using the Bath Ankylosing Spondylitis Functional Index (BASFI), the Dougados Functional Index (DFI), and and the Health Assessment Questionnaire for Spondyloarthropathy (HAQ-S), to establish whether these indicators can differentiate between these patient groups, and to ascertain how well the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) functions in patients with FM. METHODS Twenty-four patients with SpA and 70 with FM, all female, filled in 4 self-administered questionnaires: BASFI, DFI, HAQ-S, and the BASDAI; results were compared between the 2 groups. RESULTS The decline in functional ability was similar in patients with SpA and FM when assessed by BASFI, but slightly greater in the SpA group when assessed by DFI and HAQ-S. BASDAI was significantly (p = 0.018) greater in the FM group. CONCLUSION An almost similar functional decline was observed in both SpA and FM patients when measured by the indices developed for patients with AS and SpA. The specificity of BASDAI in measuring disease activity in SpA was poor, as disease activity in FM was rated higher than in SpA.

Abstract
A cohort of 74 patients with rheumatoid arthritis (RA) was followed prospectively for 15 years. At the end of the study, 148 elbows were radiographed with standard methods. The bone destruction of the humerus was measured from the anteroposterior (AP) radiograph as the bone attrition of the trochlea (TM) and the capitellum (CM). The bone destruction of the ulna was measured from the AP radiograph as the width (WO) and from the lateral radiograph as the thickness (TO) of the olecranon. Moreover, elbow joint destruction was graded by the Larsen system on a scale of 0 to 5. The relation of bone destruction to Larsen grade of the elbows was examined. The mean TM of the nonaffected (Larsen grades 0 to 1, n = 73) joints was 17.5 mm (SD, 2.1 mm; range, 10-22 mm), whereas the mean of Larsen grade 3 to 5 joints (n = 26) was 11.5 mm (SD, 5.2 mm). The mean CM of the nonaffected joints was 19.6 mm (SD, 2.6 mm; range, 15-25 mm), and the corresponding mean of Larsen grade 3 to 5 joints 15.5 mm (SD, 4.5 mm). The mean TO of the nonaffected joints was 18.9 mm (SD, 1.5 mm; range, 17-23 mm), and the mean of Larsen grade 3 to 5 joints was 13.9 mm (SD, 4.1 mm). The mean WO of the nonaffected joints was 23.3 (SD, 2.4 mm; range, 18-28 mm), and the mean of Larsen grade 3 to 5 joints was 22.4 mm (SD, 6.2 mm). Spearman correlation coefficients between TM, CM, and TO and Larsen grade of the joint were -0.45 (95% CI, -0.31 to -0.57), -0.38 (95% CI, -0.23 to -0.51), and -0.46 (95% CI, -0.31 to -0.57), respectively. Bone destruction in both the humerus and the olecranon appears to be a late consequence of rheumatoid elbow involvement. Bone loss is always present in the situation of rheumatoid elbow replacement, and it is most remarkable in Larsen grade 5 joints; the risk of preoperative and intraoperative complications due to bone destruction is significantly increased in this group.

Abstract
OBJECTIVE To evaluate radiographically the humeroulnar (HU) and humeroradial (HR) joint spaces in patients with long-term rheumatoid arthritis (RA). METHODS An inception cohort of 74 patients with RA were followed for 15 yr. At the end-point, 148 elbows were radiographed by a standard method. The HU and HR joint spaces were examined from the anteroposterior radiographs by measuring the shortest tangential distance in the middle of the joints. Destruction of the elbow joints, assessed with the Larsen method on a scale of 0-5, was studied in relation to the joint-space measurements. RESULTS Mean (s.d.) HU joint space (n=148) in RA patients was 2.5 (1.1) mm, range 0-4 mm [2.9 (0.8) mm in men and 2.4 (1.1) mm in women]. Mean (s.d.) HR joint space (n=140) was 2.3 (0.9) mm, range 0-4 mm [2.5 (0.8) mm in men and 2.3 (1.0) mm in women]. HU and HR spaces of the affected joints (Larsen grades 2-5) [1.9 (s.d. 1.1) and 1.8 (0.9) mm respectively] were notably narrower than those of the unaffected (Larsen grades 0-1) joints [3.1 (0.7) and 2.9 (0.6) mm]. All the joints graded as Larsen 4 or 5 (n=13) had a value of 0 mm for both joint spaces. Both the HU and the HR joint-space narrowing was associated with increasing destruction (Larsen grading) of the joint. [r= -0.69 (95% CI -0.77 to -0.60) and r= -0.70 (-0.78 to -0.60)]. The monotonic narrowing was significantly increasing from unaffected (Larsen 0, 1), slightly (2), moderately (3) to severely (4, 5) affected joints (P<0.001). A step in this process occurred between Larsen grades 3 and 4, when the mean joint space diminished from 1.4 and 1.5 respectively to 0 mm. CONCLUSIONS Joint-space narrowing is a frequent consequence of rheumatoid affection of the elbow joint. HR joint space decreases together with HU joint space; however, the HR joint space is already slightly narrower at the start. The narrowing is a rather late phenomenon, occurring only after erosive destruction. This should be borne in mind when using the Larsen method to evaluate changes in the elbow joint.

Abstract
OBJECTIVE To evaluate the nature of positional changes of humeroulnar (HU) and humeroradial (HR) joints in a cohort of 74 patients with seropositive and erosive rheumatoid arthritis (RA) followed up prospectively. METHODS At the 15 year follow up standard anteroposterior and lateral radiographs of 148 elbow joints were evaluated. The mediolateral HU angle of the elbow was measured from anteroposterior radiographs. The proximal subluxation of the HU joint was measured from lateral radiographs as the distance between the posterior aspect of the olecranon process and the posterior surface of the humerus. The anteroposterior subluxation of the HR joint was measured from lateral radiographs as the relation of the midpoint of head of the radius to the midpoint of the capitellum of the humerus. Destruction of the elbow joints was assessed with the Larsen method on a scale of 0 to 5 and compared with the measurements. RESULTS Mean HU angle in 148 elbows of patients with RA was 11.5 degrees (SD 6.1), range -21 degrees (varus) to 34 degrees (valgus); 9.9 degrees (SD 4.3) in men and 12.0 degrees (SD 6.4) in women. The mean HU angle, 14.4 degrees (SD 6.0) of the affected joints (Larsen grades 2-4), showed more valgus than the mean 9.8 degrees (SD 2.5) of the non-affected (Larsen grades 0 to 1) joints; totally destroyed and unstable Larsen 5 joints were excluded. Mean HU and HR subluxations, 2.0 mm (SD 3.8) and 0.8 mm, of the affected joints (Larsen 2-5) were greater than the means, -1.1 mm (SD 1.5) and -0.4 mm (SD 0.9), of the non-affected joints. Both the HU proximal subluxation and the HR anterior subluxation correlated, r(s)=0.64 (95% CI 0.53 to 0.73 ) and r(s)=0.48 (95% CI 0.34 to 0.60), with the destruction of the elbow joint. CONCLUSIONS The elbow seems to turn into valgus during rheumatoid destruction and excision of the radial head may speed up this process. However, totally unstable Larsen grade 5 joints may also have varus deformity owing to mutilating bone destruction. The ulna subluxates proximally in relation to the humerus, whereas the radius moves slightly anteriorly as a consequence of elbow involvement.

Abstract
OBJECTIVE To evaluate bone destruction, upward migration, and medialisation of the glenohumeral (GH) joint in a cohort of 74 patients with seropositive and erosive rheumatoid arthritis followed up prospectively. METHODS At the 15 year follow up 148 shoulders were radiographed by a standard method. Bone destruction in the GH joint was examined from the radiographs by four methods, of which three measured the migration and one the remodelling of the humeral head. The distances from the greater tuberosity of the humeral head to the coracoid process (medialisation distance (MD)) and to the articular surface of the humeral head (GA) have been previously developed to evaluate the preoperative offsets of the arthritic GH joint. Medial displacement index (MI) and upward migration index (UI) have been recently developed to evaluate the destructive pattern of the rheumatoid GH joint. Destruction of the GH joints was assessed by the Larsen method on a scale of 0 to 5. The relation between the measurements and the grade of destruction of the GH joints was examined. UI was compared with our previous measurements of the subacromial space. RESULTS Both the MI and the UI had a negative correlation with the GH joint destruction (Larsen grade), r=-0.49 (95% CI -0.36 to -0.60) and r=-0.58 (95% CI -0.46 to -0.68). The UI correlated significantly with the subacromial space, r=0.90 (95% CI 0.86 to 0.93). The mean MI and UI measurements of the non-affected joints were within the reported normal variation. The mean MD collapsed between Larsen grades 4 (83.0 mm) and 5 (65.5 mm). The morphology of the humeral head began to flatten and erode from the grade 3 onwards and medial head destruction was detected at grade 5. CONCLUSIONS Medialisation seems to be preceded by upward migration of the humeral head, indicating rotator cuff damage. Symptomatic Larsen grade 3 shoulders should be intensively followed up by clinical and radiological means. If a total shoulder arthroplasty is considered, an orthopaedic consultation is worthwhile at a sufficiently early stage (Larsen 3 and 4), when soft tissue structures responsible for function are still in proper condition and timing of the operative procedure can be well planned.

Abstract
AIMS In the present study we evaluated radiographically involvement of the ankle joint and its relationship to destruction of the subtalar joint in rheumatoid arthritis (RA). METHODS An inception cohort of 103 patients with seropositive RA was followed over a period of 20 years. Follow-up examinations were conducted after onset, 1, 3, 8, 15, and 20 years from entry. A total of 83 patients attended the 15-year and 68 patients the 20-year follow-up. Radiographic evaluation was performed using a lateral weight-bearing ankle radiograph. A simplified grading was applied for the talocrural joint, in which the ankles (patients) were divided into three groups: no changes, minor changes and major changes. In the end-point analysis the last radiograph was assigned. Subtalar destruction was recorded (Larsen grade > or = 2). Severity of RA in different groups was evaluated using the Larsen score of 0-100 of hands and feet. Difference between patient groups was evaluated using Cuzick's test. RESULTS At the endpoint major changes of the ankles were detected in seven patients (7%) only, minor changes were observed in 17 patients (16%). The first minor involvement of the ankle was observed at the three-year follow-up in two patients. First major changes were detected at the 15-year follow-up in three ankles of two patients. Subtalar pathology preceded that of TC joint in all ankles with major changes. In 17 patients with minor changes, simultaneous subtalar pathology was observed in all but two ankles, while preceding subtalar involvement was radiographically manifest in 13 of 21 ankles. The means of Larsen scores of 0-100 were in the three ankle grading groups 40, 54 and 63, respectively. Cuzick's test for the trend was highly significant (P < 0.001). No reconstructive surgery was performed on the ankle joint during the follow-up, whereas the subtalar joint complex was fused cumulatively in 12 patients. CONCLUSIONS The ankle joint is involved in a late stage of RA and is usually affected only in the patients with severe disease. Subtalar pathology precedes the changes in the talocrural joint almost regularly.

Abstract
OBJECTIVE To evaluate the incidence of involvement and cause of destruction of humeroulnar (HU) and humeroradial (HR) joints in a prospectively followed cohort of 74 patients with seropositive and erosive rheumatoid arthritis (RA). METHODS At the 15 year followup standard anteroposterior and lateral radiographs of 148 elbow joints were evaluated, and the grade of destruction was assessed by the Larsen method. RESULTS Erosive involvement (Larsen grade 2) was observed in 75/148 (51%) elbows in 45/74 (61%) patients; 30 patients had bilateral and 15 unilateral involvement. The incidence of mild erosions (Larsen grade 2) was 49/148 (33%), and severe erosions (Larsen 3-5) 26/148 (18%). The 13 most severely involved (Larsen grade 4-5) joints were seen in 8 (11%) patients. Erosions were most often observed on the capitellum (64 joints) and the lateral epicondyle (58 joints) of the humerus (AP view) or on the olecranon of the ulna (52 joints). The Larsen score (0-100) for peripheral joints correlated significantly with the elbow joint Larsen grade on both sides: right, r = 0.53 (95% CI 0.34 to 0.68); left, r = 0.53 (95% CI 0.34 to 0.68). CONCLUSION After 15 years more than half of the elbows and almost 2 of 3 patients with RA showed definite involvement of the elbow joint. Erosions were most often located on the capitellum and the lateral epicondyle of the humerus or the olecranon of the ulna. Severe destruction was most often bilateral.

Abstract
OBJECTIVE To compare the efficacy of combination therapy with disease-modifying antirheumatic drugs (DMARDs) versus single therapy with DMARDs in the prevention of early cervical spine changes in patients with rheumatoid arthritis (RA). METHODS One hundred ninety-five patients with recent-onset RA (mean disease duration 8 months) were randomly assigned to receive a combination of DMARDs (sulfasalazine, methotrexate, hydroxychloroquine, and prednisolone) or a single DMARD with or without prednisolone. After 2 years of followup, cervical spine radiographs were taken of 176 of these patients (85 in the combination-therapy group and 91 in the single-therapy group). These radiographs were evaluated, and the findings were correlated with the therapy strategies as well as with peripheral joint destruction and clinical and laboratory variables describing the disease activity. RESULTS Anterior atlantoaxial subluxation (aAAS), atlantoaxial impaction (AAI; i.e., vertical subluxation), and subaxial subluxation (SAS) were found in only 6 (3.4%), 2 (1.1%), and 5 (2.8%) of the patients, respectively. Interestingly, none of the patients in the combination-therapy group had aAAS or AAI. The incidences of aAAS and AAI in the single-therapy group were 6.6% and 2.2%, respectively. SAS was present in 2 patients (2.2%) in the single-therapy group and in 3 patients (3.5%) in the combination-therapy group. The difference in the incidence of aAAS between the treatment groups was statistically significant (P = 0.029). None of the patients with cervical spine changes achieved remission of RA during the study. CONCLUSION In the present study, the incidence of cervical spine subluxations in patients treated with single-drug therapy was in accord with findings of previous studies. However, none of the patients in the combination-therapy group had aAAS or AAI. These findings suggest that early, aggressive combination-DMARD therapy with sulfasalazine, methotrexate, hydroxychloroquine, and prednisolone can prevent or retard the development of rheumatoid atlantoaxial disorders.

Abstract
OBJECTIVE To describe arthritis mutilans (AM) deformity during the progression of rheumatic disease. METHODS The development of mutilans-like hand deformities in 2 patients with juvenile chronic arthritis (JCA) and in 2 patients with adult onset rheumatoid arthritis (RA) are presented. The hands of these patients were evaluated at least at two time points during the course of disease using two different scoring methods based on differently summed Larsen grades of the hand joints. RESULTS Two patients (one with JCA and one with RA) showed AM changes after a disease period of less than 10 years and 2 not until after 30 years. The patients with adult onset disease were young at the onset of joint disease. Early wrist fusions were performed on both patients showing a slow development rate. CONCLUSIONS The development rate of AM is very variable, even in patients with the same diagnoses. Wrist fusion prevents shortening of the carpus and may decrease the development rate of AM.
