Development of a specimen holder for in situ generation of pure in-plane magnetic fields in a transmission electron microscope.

As the development of quantised storage media progresses, detailed knowledge is required about the magnetisation reversal behaviour of sub-micron sized magnetic structures in external magnetic fields. Using the Lorentz mode of transmission electron microscopy (LTEM) the magnetic microstructure of thin film samples can be imaged with high spatial resolution. A novel approach for in situ magnetising experiments is described which combines the development of a custom-made sample holder which generates two orthogonal in-plane components of magnetic field in the specimen plane with the benefit of computer-controlled variation of the field. We present a specimen stage suitable for a Philips CM30 Twin/LTEM, which allows the generation of well-defined magnetic in-plane fields in the TEM.

Intra-atrial ECG is not a reliable method for positioning left internal jugular vein catheters.

BACKGROUND: ECG guidance is widely used for positioning central venous catheters (CVCs) in the superior vena cava. We noticed a higher incidence of a more perpendicular angle between the catheter tip and the vessel wall after left-sided ECG-guided catheter positioning. To investigate the value of left-sided ECG guidance, we performed this prospective study. METHODS: Of 114 patients, 53 were randomized to right and 61 to left internal jugular vein catheterization using a triple lumen catheter. Three methods to ascertain catheter tip position were sequentially applied in each patient, and the insertion depths (ID) obtained using each of the three methods were recorded: (i). ECG guidance with a Seldinger guide wire (ID-A); (ii). ECG guidance with saline 10% used as an exploring electrode (ID-B); (iii). from position ID-B, the catheter was rotated and advanced until all three lumina could be aspirated easily. The catheter was fixed in that position (ID-C). To determine final catheter tip position, intraoperative transoesophageal echocardiography (TOE) and a postoperative chest X-ray (CXR) were performed. RESULTS: The depth of insertion of a catheter using the three methods varied significantly in left-sided (P<0.001), but not in right-sided catheters. Forty-eight of 57 (84%) left-sided CVCs, correctly positioned according to ECG guidance, had to be advanced further to achieve free aspiration through all three lumina. By this stage, five of the catheter tips had been positioned in the upper right atrium as demonstrated by TOE. There were 13 malpositions (23%) after left-sided insertion. In nine catheter malpositions, undetected by ECG guidance, the angle between the catheter tip and the lateral wall of the superior vena cava exceeded 40 degrees on CXR. CONCLUSIONS: Intra-atrial ECG does not detect the junction between the superior vena cava and right atrium. It is not a reliable method for confirming position of left-sided CVCs. Post-procedural CXRs are recommended for left-sided, but not right-sided CVCs.

Disease activity and health status in rheumatoid arthritis: a case-control comparison between Norway and Lithuania.

OBJECTIVE: To compare disease characteristics and health status in patients with rheumatoid arthritis (RA) from two countries, Norway and Lithuania. METHODS: Patients were recruited from the RA registers in Vilnius (Lithuania) and Oslo (Norway). For each patient from Vilnius, a patient matched for age and sex from the Oslo register was selected. Sociodemographic characteristics, disease process, and health status were compared between the patient groups. RESULTS: 201 Lithuanian patients and 201 Norwegian patients were included. Mean (SD) age in both groups was 55.9 (10.0) years, and 83% were women. Patients from Lithuania were less often employed (27% v 42%; p=0.001), had higher disease activity expressed by the disease activity score (DAS28; mean (SD) 5.3 (1.0) v 4.4 (1.4); p<0.001), had worse physical function by the modified Health Assessment Questionnaire (MHAQ; mean (SD) 2.3 (0.8) v 1.6 (0.5); p<0.001), had more often comorbidity (73% v 53%; p<0.001) and they reported worse general health measured by Short Form-36 Health Survey (SF-36; mean (SD) 23.2 (13.5) v 44.5 (21.3); p<0.001). The proportions of patients who had used disease modifying drugs were similar, but the pattern of use differed. CONCLUSION: Important differences in employment, disease activity, physical function, and self reported health status were observed in patients with RA from two northern European countries. Socioeconomic inequalities, differences in disease management, and access to specialised health care, as well as methodological issues regarding instruments and data collection are likely explanations. These data support the view that management of RA should be adapted to country-specific needs.

Postoperative analgesia after preincisional administration of remifentanil.

AIM: The aim of this study was to assess postoperative analgesia after preincisional and postincisional administration of remifentanil. METHODS: Randomized trial, 24 hours. SETTING: University hospital, hospitalized care. PATIENTS: 48 adult patients scheduled for lumbar vertebral surgery. INTERVENTIONS: in group R5, patients received an infusion of 0.2 microg kg(-1) min(-1) remifentanil over 5 minutes, followed by a break of 15 minutes before anesthesia was started. Anesthesia was induced by infusion of 0.25 microg kg(-1) min(-1) remifentanil and a bolus of 1.5 microg kg(-1) propofol, followed by a continuous infusion of 2 to 3 microg kg(-1) h-1 propofol and 0.25 microg kg(-1) min(-1) remifentanil until end of anesthesia. In group R20, patients received 0.05 microg kg(-1) min(-1) remifentanil over 20 minutes before the induction of anesthesia. In group RL, anesthesia was induced and maintained with propofol. After surgery began, a remifentanil infusion of 0.5 microg kg(-1) min(-1) was given for 50 minutes, then reduced to 0.25 microg kg(-1) min(-1). The total remifentanil doses were similar in the 3 groups. MEASURES: patients used patient-controlled analgesia (piritramide) for postoperative pain management. They recorded pain on a numeric rating scale every half hour. STATISTICS: Kruskal-Wallis test, pairwise Mann-Withney U-test, orthogonal polynomials (pain scores). RESULTS: PATIENTS given postincisional remifentanil (RL) had the slowest decrease in postoperative pain scores (p<0.01) and the highest cumulative piritramide consumption (p<0.08). CONCLUSION: The preincisional administration of remifentanil followed by a continuous infusion of 0.25 microg kg(-1) min(-1) appears to reduce pain scores and piritramid consumption when compared with a postincisional regimen.

Remifentanil-propofol versus sufentanil-propofol anaesthesia for supratentorial craniotomy: a randomized trial.

BACKGROUND AND OBJECTIVE: Remifentanil has unique pharmacokinetics that might allow faster recovery after neurosurgery. We investigated the effects of a propofol/sufentanil versus a remifentanil/propofol regimen on the primary end-point tracheal extubation time. METHODS: In the Neurosurgery Department of a University Hospital, 36 patients awaiting craniotomy for supratentorial tumour resection were randomly assigned to one of two study groups. In the sufentanil/propofol group, anaesthesia was induced with 0.5 microg kg(-1) sufentanil and 1-2 mg kg(-1) propofol. Propofol infusion and boluses of sufentanil were administered for maintenance. In the remifentanil/propofol group, anaesthesia was started with an infusion of remifentanil (0.2-0.35 microg kg(-1) min(-1)) and a bolus of propofol (1.5-2 mg kg(-1)). Patients received a propofol infusion and a remifentanil infusion for maintenance of anaesthesia. Recovery times were taken from cessation of the propofol infusion. In addition, data about self-reported nausea and vomiting, pain and analgesic requirements were collected. RESULTS: Patients in the remifentanil/propofol group were extubated earlier (mean times 6.4 (+/- SD 4.7) versus 14.3 (+/- 9.2) min; P = 0.003). The two groups were similar with respect to postoperative nausea and vomiting, and patient-reported pain scores. Fifty per cent of the remifentanil/propofol patients and 88% of the sufentanil/propofol patients required no analgesics within 1 h after operation (P = 0.03). CONCLUSIONS: The remifentanil/propofol regimen provided quicker recovery. The two regimens were similar in terms of postoperative nausea and vomiting and patient-reported pain scores, but patients in the remifentanil/ propofol group required more analgesics within 1 h postoperatively.

Clinical decision rules in rheumatoid arthritis: do they identify patients at high risk for osteoporosis? Testing clinical criteria in a population based cohort of patients with rheumatoid arthritis recruited from the Oslo Rheumatoid Arthritis Register.

BACKGROUND: Preliminary clinical criteria based on age, inflammation, and immobility have been proposed to identify which patients with rheumatoid arthritis (RA) should be examined by dual energy x ray absorptiometry (DXA) to diagnose osteoporosis. The three item criteria have not been evaluated in male patients with RA or in the entire female RA population. OBJECTIVES: (1) To test the proposed criteria in a cohort of men and women thought to be representative of the entire underlying RA population. (2) To develop clinical decision rules, which could be applied to all patients with RA irrespective of corticosteroid use. METHODS: Clinical and demographic data were collected from a total of 287 representative patients with RA (235 (82%) women, 52 (18%) men, age range 25.3-73.1 years) from the Oslo RA register (completeness 85%). Bone mineral density (BMD) was measured in spine L2-4 (anterior-posterior view) and femoral neck by DXA. The criteria were applied and sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were calculated. RESULTS: Mean age (SD) for the women and men with RA was 56.8 (11.0) years and 61.5 (10.2) years; disease duration was 15.5 (9.5) years and 14.7 (8.6) years. Of the women 163 (69%) were postmenopausal. One hundred and seventeen (50%) women and 28 (54%) men fulfilled the three item criteria. For the diagnosis of osteoporosis (T score <or=-2.5) using the original three item criteria sensitivity in women and men was 74% and 67%, specificity 57% and 50%, PPV 32% and 29% and NPV 89% and 83%, and including weight and ever use of corticosteroids in a five item criteria sensitivity increased to 82% and 83%, specificity decreased to 45% and 45%, PPV was 29% and 31%, and NPV was 90% and 90% respectively. CONCLUSION: The novel five item criteria (age, weight, inflammation, immobility, and ever use of corticosteroids) are a more accurate tool to identify patients with RA and osteoporosis than the original three item criteria (age, inflammation, and immobility). The clinical decision rules have an acceptable sensitivity and provide a practical tool for the doctor to identify patients with RA who should have a DXA measurement performed.

Quality of life in aortic valve replacement: pulmonary autografts versus mechanical prostheses.

OBJECTIVES: We sought to determine whether the quality of life (QoL) is different in patients after aortic valve replacement with mechanical prostheses or pulmonary autografts. BACKGROUND: Quality of life after mechanical valve replacement may be affected by the risk of thromboembolism and anticoagulation, and after autograft implantation, by the risk of degeneration and re-operation especially of the homograft. METHODS: Two groups of 40 patients each--one after the autograft procedure (group I) and one after mechanical valve implantation (group II)--were matched for age, gender and length of follow-up. At latest follow-up, all patients underwent routine echocardiography, the short-form health survey (SF-36) QoL survey and an extensive psychological investigation. RESULTS: Patients with an autograft showed better QoL scales, as compared with mechanical valve recipients. The difference was significant for both the physical (72.72+/-20.00 vs. 60.27+/-26.07, p = 0.021) and psychological health sum scores (74.71+/-21.03 vs. 64.71+/-23.49, p = 0.046) and for the subtests of physical functioning (73.72+/-22.44 vs. 62.77+/-25.42, p = 0.049), physical pain (88.39+/-19.13 vs. 73.36+/-27.08, p < or = 0.006), general health perception (64.37+/-17.88 vs. 51.86+/-22.86, p < or = 0.008) and health change (61.89+/-18.94 vs. 50.11+/-24.37, p = 0.02). The QoL variables did not correlate to pressure gradients, ejection fraction and New York Heart Association functional class. Psychometric tests revealed no meaningful differences between the groups. CONCLUSIONS: This study provides some evidence that patients with pulmonary autografts have greater benefit in terms of QoL, as compared with recipients of mechanical valve substitutes.

[Development of geriatrics in Germany].

After an inquiry of the Bundesministerium für Arbeit und Sozialordnung by the responsible Landesministers, the number of inpatient geriatric institutions rose by about 34% from 1997 to 2000 and the number of partly inpatient geriatric institutions rose by 106% in the same timeframe. Outpatient geriatric rehabilitation institutions are, on the other hand, still basically nonexistent, whose number has risen from 9 to 12 since 1997. The situation is similar for mobile outpatient services, whose number doubled from 5 to 10.

[Severe multiorgan failure caused by aspiration with laryngeal mask airway].

We report a case of a 77-year-old woman who developed severe multiple organ failure after aspiration with the LMA during ureteral splinting. Two hours after induction of anaesthesia the urologists decided for nephrostomy in prone position. Therefore the patient was intubated. During removal of the LMA bilious secretion was recognized inside the LMA and in the pharynx. Endotracheal suction and immediate bronchoscopy showed severe aspiration. After the operation the patient was submitted to the ICU. She developed a severe multiple organ failure within 12 hours. Recovery took 54 days. The discussion is focussed on risk factors for the use of the LMA, adequate intraoperative monitoring, possible disadvantages of the applied anaesthetic technique and initial treatment after aspiration.

Sicca symptoms and secondary Sjögren's syndrome in systemic lupus erythematosus: comparison with rheumatoid arthritis and correlation with disease variables.

OBJECTIVE: Firstly, to study the prevalence of ocular and oral sicca symptoms, reduced tear and saliva production, and the minimum frequency of secondary Sjögren's syndrome (sSS) in systemic lupus erythematosus (SLE). Secondly, to compare sicca symptoms and findings with those of matched patients with rheumatoid arthritis (RA), and sicca symptoms with those in healthy controls. Finally, to study possible associations of clinical variables with sicca symptoms and sSS in SLE. METHODS: Self reported sicca symptoms were recorded in 81 patients with SLE aged < or =70, 81 matched patients with RA, and 81 matched healthy controls. Other study variables included Schirmer-I test (S1T), unstimulated whole saliva, health status measures (in SLE and RA), disease activity, accumulated organ damage, and serological markers (in SLE). RESULTS: A significantly higher proportion of patients with SLE reported sicca symptoms than healthy controls. Further, a significantly higher proportion reported ocular sicca symptoms (43 and 21%, respectively) and had pathologically reduced S1T compared with RA (46 and 21%, respectively). No difference was seen in oral sicca symptoms and saliva production. In SLE, sicca symptoms were associated with fatigue, and sSS with anti-SSB or anti-SSA antibodies, or both. CONCLUSIONS: An increased prevalence of sicca symptoms was found in patients with SLE compared with controls, and a higher prevalence of ocular sicca symptoms and reduced tear production in SLE compared with RA. Sicca problems should be considered in the care of patients with SLE, especially those with anti-SSB and/or anti-SSA antibodies who have sicca symptoms and fatigue.

Criteria for TNF-targeted therapy in rheumatoid arthritis: estimates of the number of patients potentially eligible.

Tumour necrosis factor (TNF) antagonists or blocking agents represent a major advance in the treatment of rheumatoid arthritis (RA), but their use raises economic concerns because of the high drug cost. Population-based patient registers with clinical data allow the estimation of the proportion of patients with RA who are eligible for TNF antagonist therapy according to recent consensus statements on TNF-targeted therapy. Data were derived from a representative county-based (500,000 population) register of patients with RA. Of 894 patients aged between 18 and 70 years, 636 (71%) [females 80%, mean (SD) age 53.6 (12.2) years and mean (SD) disease duration 12.2 (9.3) years] had a clinical and radiographic examination. The eligibility for TNF-targeted therapy was estimated from the following criteria: (i) previous or current therapy with at least one disease-modifying antirheumatic agent (DMARD); and (ii) active disease. Disease activity criteria were set to 28-swollen joint count (28-SJC) > or = 6, 28-tender joint count > or = 6, and erythrocyte sedimentation rate (ESR) > or = 28 mm/hour or C-reactive protein (CRP) > or = 20 mg/L. Sensitivity analyses were performed varying some of these disease activity parameters. Of the 636 patients, as many as 526 (83%) had previously or were currently using DMARDs and 98 (15%) fulfilled both the DMARD and activity criteria, thus being the maximum number of patients considered for TNF-targeted therapy. If the most stringent criteria were used (ever DMARD, 28-SJC > or = 12 and ESR > or = 50 mm/hour or CRP > or = 40 mg/L) only 15 of the 626 (2%) would be candidates for TNF-targeted therapy. In a population of 1 million, assuming a prevalence of 2000 patients with RA under the age of 70 years, the number of candidates for TNF-targeted therapy would be 40 to 300, depending on the disease activity criteria. Stringent ESR and CRP criteria would lead to a major reduction in the number of eligible patients. These utilisation data imply annual drug costs in the range of $US 480,000 to $US 3,600,000 for TNF antagonists for RA per 1 million population. Further economic evaluations are needed to determine for which groups such treatment is warranted from a health economics perspective.

[Rocuronium or vecuronium for intubation for short operations in the preschool age? Effects on time in the operating room and postoperative phase].

This prospective randomized study compares the effects of rocuronium (R) and vecuronium (V) on the early postoperative period in infants. Forty-eight infants between the ages of three and six, scheduled for elective ENT procedures, were studied after prior approval of local ethics committee and informed parental consent. All children were premedicated with chlorprotixene and belladonna. Anaesthesia was induced with 5 mg/kg thiopentone and 1 vol.-% halothane. Subsequently, 0.4 mg/kg rocuronium or 0.075 mg/kg vecuronium were administered, respectively. Anaesthesia and post-operative care were conducted by independent anaesthetists, who were unaware of the drug used and of the relaxometric data obtained. All children were monitored in the recovery room by pulse oximetry until they reached a Steward Score of 6. Demographic data did not differ between the groups. No differences were recorded between the non-depolarizing relaxants regarding intubation time (R: 24.1 +/- 4.2 min, V: 25.8 +/- 6.8 min) and the time interval from end extubation to leaving the operating theatre (R: 2.3 +/- 0.8 min, V: 2.6 +/- 1.2 min), respectively. Similarly, no differences in SaO2 were noted during the recovery period in the recovery room. Significant differences between the non-depolarizing relaxants were found in the TOF-ratios at extubation (R: 0.73 +/- 0.31 min, V: 0.48 +/- 0.34 min) and arrival in the recovery room (R: 0.88 +/- 0.21 min, V: 0.69 +/- 0.26 min). 0.4 mg/kg Rocuronium and 0.075 mg/kg vecuronium can be used for intubation during short operations on pre-school children. Rocuronium may be the better alternative, due to its faster neuromuscular recovery properties.

Personality traits, coping styles, and mood in patients awaiting lumbar-disc surgery.

The objective of this study was to characterize personality traits, coping styles, and mood state in patients with lumbar-disc disorders. In two studies (N = 112; N = 84) patients expecting lumbar-disc surgery were compared to patients awaiting another kind of surgery. Personality traits and coping styles were assessed with a personality inventory (FPI-R) and a stress-coping questionnaire (SVF). Mood was measured several times before surgery using a multidimensional self-report inventory [BSKE (EWL)]. The same inventory was used by anesthetists to rate the patient's mood. Heart rate and blood pressure also were measured. The groups did not differ with regard to personality traits, coping styles, self-reported mood state, or somatic variables. The physicians rated lumbar-disc patients as being in a better mood than control patients. Significant correlations between self-ratings and physician ratings were not observed. The results characterize lumbar-disc patients as a subgroup that is not different from other surgery patients and, therefore, does not need a specific form of psychological management prior to surgery. The importance of using patients expecting another type of surgery as a control group rather than healthy individuals is clearly demonstrated.

Bone mineral density and frequency of osteoporosis in female patients with rheumatoid arthritis: results from 394 patients in the Oslo County Rheumatoid Arthritis register.

OBJECTIVE: To examine the bone mineral density (BMD), frequency of osteoporosis, and risk factors for BMD reduction in a representative population of female rheumatoid arthritis (RA) patients ages 20-70 years. METHODS: BMD in the femoral neck, total hip, and spine L2-4 (anterior-posterior view) was measured in 394 RA patients recruited from a validated county RA register (completeness 85%) comprising 721 women ages 20-70 years. BMD was measured with dual-energy x-ray absorptiometry, and age-specific values were compared with pooled values from a European/US population of healthy subjects free from earlier fractures, chronic diseases, and medications influencing bone metabolism. A multiple linear regression model was used to determine individual predictors of BMD. RESULTS: No statistically significant differences were found in demographic, disease activity, disease severity, or health status parameters between the RA register patients in whom BMD was measured and the remaining register patients. Femoral neck BMD was significantly reduced by 4.2% in the age group 50-59 years, and by 5.0% in those ages 60-70 years. For BMD in the total hip, the significant reductions were 3.7%, 6.0%, and 8.5% in the age groups 40-49 years, 50-59 years, and 60-70 years, respectively. No significant reduction in spine L2-4 BMD was found. A 2-fold increased frequency of osteoporosis was observed in all 4 age groups of RA patients compared with the reference population, ranging from 0% to 28.6% in the femoral neck, 0% to 29.9% in the total hip, and 1.8% to 31.5% in the spine. Predictors of reduced BMD were as follows: at the femoral neck, older age, low body weight, current use of corticosteroids, greater physical disability (as measured by the modified Health Assessment Questionnaire [M-HAQ]), and presence of rheumatoid factor; at the total hip, older age, low weight, current use of corticosteroids, and higher M-HAQ disability score; and at the lumbar spine, older age, low weight, and current use of corticosteroids. CONCLUSION: Register-based prevalence data on BMD reduction in female RA patients ages 20-70 years are presented for the first time in this report, which demonstrates a 2-fold increase in osteoporosis in this representative population.

Reduced bone mineral density in male rheumatoid arthritis patients: frequencies and associations with demographic and disease variables in ninety-four patients in the Oslo County Rheumatoid Arthritis Register.

OBJECTIVE: To examine reductions in bone mineral density (BMD) and factors associated with reduced BMD in 94 male rheumatoid arthritis (RA) registry patients ages 20-70 years. METHODS: Dual-energy x-ray absorptiometry was used to measure BMD in the anteroposterior lumbar spine at L2-LA, the femoral neck, and the total hip, and clinical data were collected. The patients were recruited from a validated county RA registry (completeness 85%) comprising 192 men ages 20-70 years. Age-specific BMD values were compared with a pooled healthy European/United States population. Bivariate and multivariate analyses were performed to determine demographic and disease-related associations with BMD and reduced bone mass (Z score of < or =1 SD below the mean value in controls). RESULTS: A statistically significant BMD reduction was found only for the oldest age group (60-70 years): 5.2% reduction in the femoral neck and 6.9% in the total hip. No BMD reduction was found at L2-L4. The proportions (95% confidence intervals) of RA patients with Z scores of < or =1 SD below control (16% expected) were 30.9% (21.6-40.2) for L2-L4, 30.8% (95% CI 21.3-40.3) for the femoral neck, and 33.0% (95% CI 23.3-42.7) for the total hip. Disease activity and severity measures were, in general, not associated with BMD or reduced bone mass. CONCLUSION: A 2-fold statistically significant increased frequency of patients with reduced bone mass (Z score of < or =1 SD below control; 16% expected) was found for both the spine and the hip. The only significant reduction in BMD by age group was for the hip in patients who were ages 60-70 years, with no reduction in L2-LA BMD. Multivariate analyses did not reveal consistent associations between reduced BMD and demographic or disease variables.

[Management and methodological approaches for the assessment of emotional states in anesthesiology].

In anaesthesiology emotional states are of great importance. Reduction of anxiety and sedation in the preoperative preparation as well as stress reduction and the process of recovery are a challenge for anaesthetists as perioperative physicians. As emotions have different dimensions of manifestation like experience, expression, behaviour and somatic indicators, all these are needed to describe emotions sufficiently. In a multidimensional approach for the measure of emotional states, the different dimensions, their relationships and interactions are taken into account. The methodological approaches to registration of emotions in the anaesthesiological context are heterogeneous. In this summary the possibilities are differentiated by the source of information. Self-rating by the patient, rating by the observer, expression and behaviour and somatic indicators are taken into consideration. Analysis of the methods for the assessment of emotional states in anaesthesiological setting leads to the following recommendations: The most sensitive source of information is the patient. The rating scale used should be multidimensional and it should take specific as well as unspecific emotional aspects into account. As there are enough rating scales thoroughly developed and up to the demands of the classical test-theory, no ad hoc developed scales should be used. The rating of the emotional state should be supplemented by a rating of the physical state. The rating by the observer can be a valuable addition. The agreement between observers and the reliability of the method must be guaranteed. At presence there is no alternative in clinical practice to simple autonomic parameters such as blood pressure and heart rate as somatic indicators of emotion. Still it is important to consider the normal values for the individual patient. It is necessary to develop and to evaluate simple methods to register characteristics of expression in clinical context.

The course of rheumatoid arthritis and predictors of psychological, physical and radiographic outcome after 5 years of follow-up.

OBJECTIVE: : To examine the course of RA over 5 yr and identify predictors of psychological, physical and radiographic outcome. PATIENTS AND METHODS: Out of 238 patients with rheumatoid arthritis of no more than 4 (mean 2.2) yr duration, 182 (76%) completed a clinical examination with follow-up at 1, 2, and 5 yr. The course of the disease was assessed by measures of psychological and physical health status, disease process and radiographic damage. RESULTS: : Over 5 yr we observed at a group level a stable disease course for measures of disease process, psychological and physical health status. Radiographic damage progressed. Health status and radiographic damage after 5 yr were predicted by the baseline measures for the respective outcome. Physical function was also predicted by age and by psychological status when the physical dimension of the Arthritis Impact Measurement Scales was chosen as outcome variable. Erythrocyte sedimentation rate and presence of rheumatoid factor predicted radiographic progression. CONCLUSIONS: : The 5 yr course of RA was characterized by preserved health status measures and clinically preserved disease process measures, whereas joint damage progressed steadily. Outcomes after 5 yr can be predicted partly by certain measures at baseline.
