    Magnetic resonance imaging (MRI) is a sensitive diagnostic modality for the detection of inflammatory changes in peripheral joints. Nevertheless, the widespread clinical use of MRI in assessing patients with early rheumatoid arthritis is still hampered by the technical complexity and higher cost of MRI compared with conventional radiography. This overview summarizes the results of recent research and gives practical tips on how to perform MRI of the hands. The authors present an MR protocol for hand imaging, discuss the pros and cons of low-field MR scanners, and outline pitfalls and artifacts. The MRI changes associated with rheumatoid arthritis such as synovitis, tenosynovitis, erosions, and bone marrow edema are described including their prognostic significance. The proven facts on the validation and grading of MR changes in rheumatoid arthritis are summarized. Finally, the role of MRI in the differential diagnosis of arthritis is critically discussed.

    Rheumatoid arthritis is primarily a disease of the synovial membrane. To demonstrate synovial changes it is necessary to show adequate detail of the soft tissue. This is best obtained by using industrial film and by hand-processing. The anatomy of the hand and the radiological appearance of rheumatoid arthritis are described. (author)

    The aim of the study was to characterize the pattern of radiographic changes in the hands and feet of rheumatoid arthritis in Saudi patients. The radiographs of hands and feet of rheumatoid arthritis patients attending rheumatology outpatient clinics of King Khalid University Hospital in Riyadh, Kingdom of Saudi Arabia, over the period extending from March to June 2001, were examined and reported for the presence of osteopenia, joint space narrowing, and erosions. Fifty-six rheumatoid arthritis patients were studied. Their mean age was 50 + 1.9 years, and mean disease duration was 9.07 + 0.84 years. Generalized osteopenia was seen in 16/56 (29%) and periarticular osteopenia in 38/56 (68%). Joint space narrowing was present in 9/56 (16%) of feet and 35/56 (63%) of hand x-rays. Erosions were seen in 3/56 (6%) of feet and in 22/56 (39%) of hand x-rays. Significant correlation was seen between joints space narrowing, joint erosions, and disease duration. Radiographic changes in hands and feet of Saudi rheumatoid arthritis patients are less severe than those reported from the West, and the pattern is also different with less affection of the feet.

    to evaluate the effects of compression gloves in adults with rheumatoid arthritis and hand osteoarthritis. Systematic review of randomized controlled trials identified from MEDLINE, CINAHL, AMED, PEDro, OT Seeker, The Cochrane Library, ISI Web of Knowledge, Science Direct and PubMed from their inceptions to January 2015. Methodological quality of identified trials was evaluated using the PEDro scale by three independent assessors. Effects were summarized descriptively. Four trials (n=8-24; total n=74), comparing night wear of full-length finger compression gloves with placebo gloves, were assessed. Three were of moderate (PEDro score 4-5) and one low (score 3) methodological quality. Effect sizes or standardized mean differences could not be calculated to compare trials due to poor data reporting. In rheumatoid arthritis, finger joint swelling was significantly reduced, but results for pain and stiffness were inconclusive and no differences in grip strength and dexterity were identified. One study reported similar effects in pain, stiffness and finger joint swelling from both compression and thermal placebo gloves. Only one study evaluated gloves in hand osteoarthritis (n=5) with no differences. All the trials identified were small with a high risk of Type I and II errors. Evidence for the effectiveness of compression gloves worn at night is inconclusive in rheumatoid arthritis and hand osteoarthritis. © The Author(s) 2015.

    Full Text Available Objectives: The hand is one of the main elements of the rehabilitation of patients with rheumatoid arthritis (RA due to deformities, which occur in approximately 90% of patients. It is a serious problem, both in the psychological and functional aspect, connected with muscle strength reduction, a limited range of motion and non-acceptance of the changes in the shape of the limb. The study aimed to assess the effect of rehabilitation on the function of the hand in rheumatoid arthritis. Material and methods: The study group consisted of 40 women with RA. The patients had been previously treated at the Rehabilitation Department of the National Institute of Geriatrics, Rheumatology and Rehabilitation in Warsaw. The study group underwent 3 weeks of rehabilitation involving individual therapy, exercises with equipment, patient education and physical therapy. The control group included women without a diagnosis of RA, hands pain-free and fully mobile. In both groups the hand was assessed for grip value, grip quality and manipulative ability. In the study group the basis of pain intensity was noted. The measurements were performed twice – prior to the rehabilitation and after 3 weeks of rehabilitation in women with RA and once in women without hand problems. Results : The results obtained revealed marked limitation of hand function in patients with rheumatoid arthritis. The treatment resulted in an improvement of all assessed parameters except cylindrical grip, in which only a part of the findings was statistically significant. Conclusions : The analysis of the study material showed that appropriately adjusted and conducted hand physiotherapy in women with rheumatoid arthritis contributed to the improvement of its function by pain reduction, improved value and quality of grip, and also increased manipulative ability.

    Aim: evaluation of the effectiveness of radiosynoviorthesis (RSO) in osteoarthritis and other disorders with concomitant synovitis versus rheumatoid arthritis by means of a standardized questionnaire. Patients, methods: 803 RSO treatments were monitored in 691 patients by standardized questionnaires of 7 centers in 3 countries. Patients were assigned to 3 groups according to their age (20-40, 41-60, 61-80 years). Additionally, the data were analyzed separately for patients with rheumatoid arthritis (group A) and those with osteoarthritis, psoriasis arthritis, pigmental villonodular synovitis or persistent effusions after joint replacement (group B). Results: ameliorations of joint pain, swelling/effusion or flexibility were found in 80% of group A and 56% of group B (p <0.01). Quality of life improved in 78% of group A and 59% of group B (p <0.01). The response rate was similar for small- and large-sized joints in group A, but significantly higher for large-sized joints in group B (p <0.01). The positive effects on joint pain, swelling/effusion or flexibility lasted longer in group A (p <0.01). Repeated RSOs were as effective as initial ones. The clinical outcome was neither influenced by age, nor gender, nor transient immobilisation for 48 hours after RSO. Conclusion: although slightly more efficient in rheumatoid arthritis, RSO represents an effective treatment option also in osteoarthritis and other disorders with concomitant synovitis. (orig.)

    Plain films of the calcanea of 768 patients with confirmed rheumatoid arthritis were examined retrospectively with reference to inflammatory rheumatic changes. 42 patients (5.5%) showed an erosion of the posterior upper calcaneal margin related to an Achilles bursitis. In three patients there were additional plantar erosions. The Achilles bursitis was bilateral in 50% of cases, particularly in patients in stages 2 and 3 according to Steinbrocker. In the majority of bilateral cases (62%) the size or shape of the lesions was asymmetrical. Our observations indicate that involvement of the os calcis is not uncommon in rheumatoid arthritis; routine examination of this bone would appear to be indicated even in patients without symptoms. Since the defect is unilateral in half the patients, unilateral occurrence of an erosive lesion cannot be regarded as a criterion for a bacterial-inflammatory bursitis. Contrary to the symmetrical involvement of joints in the hands in rheumatoid arthritis, defects in the calcanea are often unilateral or asymmetrical. (orig.) [Deutsch] Die Nativroentgenaufnahmen des Fersenbeins von 768 Patienten mit gesicherter chronischer Polyarthritis wurden retrospektiv hinsichtlich des Auftretens entzuendlich-rheumatischer Veraenderungen beurteilt. 42 Patienten (5,5%) zeigten eine Erosion der hinteren oberen Fersenbeinkante im Sinne eines Achillobursitisdefektes. Bei drei Patienten gelangte zusaetzlich eine plantare Erosion zur Darstellung. Der Achillobursitisdefekt war in 50% der Faelle beidseitig ausgebildet, wobei das bilaterale Auftreten bei Patienten in den Stadien II und III nach Steinbrocker ueberwog. Bei bilateralem Befall waren die Laesionen allerdings in der Mehrzahl der Faelle (62%) hinsichtlich Groesse und/oder Form asymmetrisch ausgebildet. Unsere Beobachtungen belegen, dass eine Fersenbeinbeteiligung im Rahmen der chronischen Polyarthritis nicht selten auftritt, weshalb routinemaessig Roentgenaufnahmen des Fersenbeins bei Patienten mit

    In a prospective investigation the diagnostic accuracy of filmscreen and digital radiography in rheumatoid arthritis of hands was compared. Seventy hands of 36 patients with established rheumatoid arthritis were included in the study. Each of 11 joints in every hand was evaluated regarding the following radiologic parameters: soft tissue swelling, joint space narrowing, erosions and periarticular osteopenia. The digital images were obtained with storage phosphor image plates and evaluated in 2 forms; as digital hard-copy on film and on a monitor of an interactive workstation. The digital images had a resolution of either 3.33 or 5.0 lp/mm. ROC curves were constructed and comparing the area under the curves no significant difference was found between the 3 different imaging forms in either resolution group for soft tissue swelling, joint space narrowing and erosions. The film-screen image evaluation of periarticular osteopenia was significantly better than the digital hard-copy one in the 3.33 lp/mm resolution group, but no significant difference was found in the 5.0 lp/mm group. These results support the view that currently available digital systems are capable of adequate diagnostic performance. (orig.)

    Soft tissue radiography of the hands using the mammographic immersion technique was performed on 119 patients, having definite or classical rheumatoid arthritis, and on 123 controls of matching age, sex, and professional distribution. A total of 7744 finger joints and carpal borders were investigated for joint swelling, periarticular edema, pre-erosive and erosive bone changes, joint space narrowing, and osteoarthritic joint margin spurs. Slight joint swelling and pre-erosive bone changes were found in connection with osteoarthritic joint changes in elderly control patients. Periarticular edema and moderate to massive joint swelling were quite reliable signs for synovitis. The incidence of pre-erosive bone signs was significantly greater in the rheumatoid arthritis group than in the control group, especially in patients less than 60 years old. These signs can be regarded as suggestive of rheumatoid arthritis; probability diagnosis could be performed using these signs and the Bayesian approach.

    Rheumatoid arthritis causes changes in the soft tissues in the metacarpal portion of the hand which can be demonstrated by low Kv exposures. Indirect signs of inflammation consist of oedema extending from the synovial compartments to the skin, the subcutaneous tissues, the intermuscular fat septa and the peritendinous tissue. Increased blood flow leads to dilatation of veins. Direct signs of inflammation consists of tenosynovitis and synovitis of the joints, with enlargement of the corresponding compartments. Limited mobility of the hand over a long period, or improvement in motility are paralleled by changes in muscle mass.

    Establishing an early and reliable diagnosis of rheumatoid arthritis (RA) is of major importance but can be a great clinical challenge leading to direct therapeutic consequences. No single epidemiological, genetic, clinical, serological or radiological test exists which can exclusively diagnose RA. In general diagnosis of RA includes a case history, clinical signs, laboratory abnormalities and radiological examinations, viz. conventional radiography of the joints of the hands and feet. This review summarizes the most important radiological features of RA and the radiological findings of its closest differential diagnoses. (orig.) [German] Eine fruehe Diagnosestellung bei rheumatoider Arthritis (RA) stellt eine grosse klinische Herausforderung dar, da sich daraus unmittelbare therapeutische Konsequenzen ableiten. Es gibt keinen epidemiologischen, genetischen, klinischen, serologischen oder radiologischen Test, mit dessen alleiniger Anwendung die Diagnose der RA definitiv gestellt werden kann. Die Diagnose der RA erfolgt durch die Kombination von Patientenanamnese, klinischen Zeichen und serologischen Biomarkern in Zusammenschau mit der radiologischen Diagnostik, allen voran der Anwendung konventioneller Roentgenbilder der Haende und Fuesse. In diesem Uebersichtsartikel werden die wichtigsten radiologischen Merkmale zur Diagnose der RA und der diagnostisch haeufigsten Differenzialerkrankungen dargestellt. (orig.)

    Full Text Available Background. Rheumatoid arthritis (RA, met in the literature also as chronic evolving polyarthritis, is a chronic inflammatory disease, which typically involves the small and medium joints, with a symmetric distribution. Clinical studies shown that a proportion of patients with RA, without measurable rheumatoid factors are a distinct entity from those patients with seropositive RA. Around one third of patients with RA are seronegative for those two serological markers, the rheumatoid factors (RF and anti-citrullinated peptide antibodies (Anti-CCP. Hands are the most frequently affected in both seropositive and seronegative RA and the first joints involved in the inflammatory process are the metacarpo-phalangeal joints, IFP joints and the radiocarpian joint. The big joints become later symptomatic, after the small joints are affected. Materials and methods: 66 patients files and the personal records of the patients consecutively admitted in the Rheumatology Department of the Clinical Emergency County Hospital Constanta. Patients from county Constanta were included in the study, with diagnosis of rheumatoid arthritis (diagnosis confirmed at least 2 years ago, including both forms (seropositive and seronegative of the disease. The complete clinical exam was done for the patients included in the study, following the identification of the active joint disease. The mechanical status of the joint was observed by a single evaluator for each of those 66 patients with RA, with special focus on the presence of the deformities / ankyloses of the hands joints. Therefore, there were evaluated: the mobility (the number of the joints with limited movements, deformities, ankyloses (the number of the joints without mobility. The joint mobility was assessed by counting the hand joints with limited movements and the worsening of the prehension function. The presence of the following hand deformities was followed: fingers in “swan neck”, “fusiform fingers

    Rheumatoid arthritis (RA) commonly reduces hand function. We systematically reviewed trials to investigate effects of home hand exercise programmes on hand symptoms and function in RA. We searched: Medline (1946-), AMED, CINAHL, Physiotherapy Evidence Database, OT Seeker, the Cochrane Library, ISI Web of Science from inception to January 2016. Nineteen trials were evaluated. Only three were randomized controlled trials with a low risk of bias (n = 665). Significant short-term improvements occurred in hand function, pain and grip strength, with long-term improvements in hand and upper limb function and pinch strength. Heterogeneity of outcome measures meant meta-analysis was not possible. Evaluation of low and moderate risk of bias trials indicated high-intensity home hand exercise programmes led to better short-term outcomes than low-intensity programmes. Such programmes are cost-effective. Further research is required to evaluate methods of helping people with RA maintain long-term home hand exercise. © The Author 2016.

    To examine the feasibility of a clinical trial on a novel, home-based task-oriented training with conventional hand exercises in people with rheumatoid arthritis or hand osteoarthritis. To explore the experiences of participants who completed their respective home exercise programmes. Thirty volunteer participants aged between 30 and 60 years and diagnosed with rheumatoid arthritis or hand osteoarthritis were proposed for a single-center, assessor-blinded, randomized controlled trial ( ClinicalTrials.gov : NCT01635582). Participants received task-oriented training with interactive computer games and objects of daily life or finger mobility and strengthening exercises. Both programmes were home based and were done four sessions per week with 20 minutes each session for 6 weeks. Major feasibility outcomes were number of volunteers screened, randomized, and retained; completion of blinded assessments, exercise training, and home exercise sessions; equipment and data management; and clinical outcomes of hand function. Reaching the recruitment target in 18 months and achieving exercise compliance >80% were set as success criteria. Concurrent with the trial, focus group interviews explored experiences of those participants who completed their respective programmes. After trial initiation, revisions in inclusion criteria were required to promote recruitment. A total of 17 participants were randomized and 15 were retained. Completion of assessments, exercise training, and home exercise sessions; equipment and data collection and management demonstrated excellent feasibility. Both groups improved in hand function outcomes and exercise compliance was above 85%. Participants perceived both programmes as appropriate and acceptable. Participants who completed task-oriented training also agreed that playing different computer games was enjoyable, engaging, and motivating. Findings demonstrate initial evidence on recruitment, feasibility of trial procedures, and acceptability of

    Full Text Available Abstract Background Rheumatoid Arthritis (RA commonly affects the hands and wrists with inflammation, deformity, pain, weakness and restricted mobility leading to reduced function. The effectiveness of exercise for RA hands is uncertain, although evidence from small scale studies is promising. The Strengthening And Stretching for Rheumatoid Arthritis of the Hand (SARAH trial is a pragmatic, multi-centre randomised controlled trial evaluating the clinical and cost effectiveness of adding an optimised exercise programme for hands and upper limbs to best practice usual care for patients with RA. Methods/design 480 participants with problematic RA hands will be recruited through 17 NHS trusts. Treatments will be provided by physiotherapists and occupational therapists. Participants will be individually randomised to receive either best practice usual care (joint protection advice, general exercise advice, functional splinting and assistive devices or best practice usual care supplemented with an individualised exercise programme of strengthening and stretching exercises. The study assessors will be blinded to treatment allocation and will follow participants up at four and 12 months. The primary outcome measure is the Hand function subscale of the Michigan Hand Outcome Questionnaire, and secondary outcomes include hand and wrist impairment measures, quality of life, and resource use. Economic and qualitative studies will also be carried out in parallel. Discussion This paper describes the design and development of a trial protocol of a complex intervention study based in therapy out-patient departments. The findings will provide evidence to support or refute the use of an optimised exercise programme for RA of the hand in addition to best practice usual care.

    Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by pain, swelling and progressive destruction of the joints leading to loss of function and invalidity. The bone destruction in RA is characterised by two distinct features: structural joint damage and hand bone loss, and their prevention is an important treatment goal. Inhibitors of tumour necrosis factor alpha (TNF-inhibitors) have markedly improved the treatment options in RA patients who fail treatment with conventional synthetic Disease Modifying Anti Rheumatic Drugs (sDMARDS), but their effectiveness with regards to structural joint damage and hand bone loss, predictors thereof and the association with disease activity during treatment have mainly been investigated in randomized controlled trials (RCTs) with limited generalizability due to strict in- and exclusion criteria.
 The main aim of the PhD thesis was to assess and predict structural joint damage and hand bone loss in patients with early and established RA treated with sDMARDs and TNF-inhibitors. This was investigated in two cohorts: A) The "DANBIO X-ray study": an observational, nationwide, longitudinal cohort study of established RA patients treated in clinical practice who initiated TNF-inhibitor treatment after failure of sDMARDs and B) The "OPERA study": a randomized controlled trial of sDMARD-naïve patients with early RA treated with methotrexate (MTX) and intraarticular glucocorticoid injections in combination with adalimumab or placebo-adalimumab. Structural joint damage progression was assessed with the Sharp/van der Heijde radiographic method and hand bone loss was assessed with Digital X-ray Radiogrammetry. 
From the studies presented in the PhD thesis the following was concluded:
 Structural joint damage progression and hand bone loss were significantly lower during two years of TNF-inhibitor treatment compared to the previous two years of sDMARD-treatment in the DANBIO X-ray Study. The majority of patients had

    The aim of this study was to determine the ability of joint scan and bone scan of hands and feet, in patients with rheumatoid arthritis, to localize the altered joints. The sensitivity, the specificity, the positive predictive value (PPV) and the negative predictive value (NPV) of joint scan were determined in comparison with clinical joint assessment. Fifteen patients (780 joints) were clinically examined (pain and synovitis); during the same day, a bone scan and a joint scan were realized by oxidronate 99m Tc intravenous injection. Patients were scanned 5 minutes (tissual time, T t ) and 3 hours 1/4 (bone time, T 0 ) after the administration. The uptake of the bi-phosphonate was evaluated with a qualitative method using a grey scale. The uptake of 99m Tc oxidronate was quantitated using an extra-articular region of interest. The sensitivity, specificity, PPV and NPV of the scan at Tt were 46%, 96%, 85% et 78%. The same parameters were 75%, 66%, 53% and 84% for the scan realized at T 0 . The joint scan has showed 22% of false positive. These false positives could be a consequence of an earlier detection of joint alterations by scan. The joint scan should forecast the evolution of joints in patients with rheumatoid arthritis. (author)

    Full Text Available Rheumatoid arthritis (RA often results in impairments in upper extremities, especially in the small joints of hand. Involvement of hand brings limitations in activities of daily living. However, it is commonly observed that patient-reported functional status of hand does not always corresponds to their actual physical performance in the clinical setting. The aim of this pilot study is to investigate the relationship between patient self-reported and objectively measured hand functions in patients with RA. Twenty-six patients (51±13 years with RA diagnosis participated in the study. Hand grip and pinch (lateral, bipod, tripod strengths were measured and Jebsen Hand Function Test (JHFT was performed for objective functional performance. Duruöz Hand Index and Beck Depression Inventory - Turkish version were completed by patients. Grip and all three-pinch strength results significantly correlated with Duruöz Hand Index scores (p<0.05. JHFT results except the sentence writing also correlated with the Duruöz scores (p<0.05. Our results showed that self-reported outcome scales might be used for determining functional level of hand in patients with RA in rheumatology practice. Objective quantitative functional tests are the best methods in evaluating functional level of hand, but require valid and reliable equipment with accurate calibration. Therefore, in case of unavailability of objective assessment tools, patient-reported scales may also reflect the real status of hand functions.

    To determine the frequency of radiographic abnormalities in hand/wrist radiographs of children with newly diagnosed polyarticular juvenile rheumatoid arthritis (polyJRA) because radiographs of small joints are an important tool in assessing outcomes in RA and there are clinical similarities between RA and polyJRA. A medical record review was performed to identify cases of polyJRA seen at Mayo Clinic from January 1, 1994, to December 31, 2001. Hand/wrist radiographs, obtained at the time of diagnosis, were reviewed by 3 radiologists with attention to periarticular osteopenia, joint space narrowing (JSN), or erosion. At least 2 radiologists had to independently identify abnormal findings on the same radiograph. The relative carpal length (RCL), judged by Poznanski's method, was also determined. From the review of 159 medical records, 60 cases of newly diagnosed polyJRA were identified. Twenty-five of these had hand/wrist radiographs at diagnosis; 18 sets were available for this study. Of those, 2/3 were female, 6% (1/18) had subcutaneous nodules, 7% (1/14) had elevated levels of serum rheumatoid factor, and 44% (7/16) had elevated serum levels of antinuclear antibodies. Median age at diagnosis was 10.2 years, median duration of hand/wrist symptoms at diagnosis was 10 months, and median number of joints with either swelling, pain on range of motion (ROM), or limited ROM was 14.5. Sixty-one percent of radiographs taken at the time of diagnosis of polyJRA were abnormal. While 44% had periarticular osteopenia, 28% had either erosions or JSN. Six (33%) had RCL > 2 SD below the mean for age. Five (83%) of those with RCL, > 2 SD below the mean for age, had periarticular osteopenia, JSN, or erosion. We conclude the frequency of abnormal hand/wrist radiographs is very high very early in the course of polyJRA. More studies are needed to determine to what extent these radiographic abnormalities correlate with clinical outcomes.

    Significant restriction in the ability to participate in home, work and community life results from pain, fatigue, joint damage, stiffness and reduced joint range of motion and muscle strength in people with rheumatoid arthritis or osteoarthritis of the hand. With modest evidence on the therapeutic effectiveness of conventional hand exercises, a task-oriented training program via real life object manipulations has been developed for people with arthritis. An innovative, computer-based gaming platform that allows a broad range of common objects to be seamlessly transformed into therapeutic input devices through instrumentation with a motion-sense mouse has also been designed. Personalized objects are selected to target specific training goals such as graded finger mobility, strength, endurance or fine/gross dexterous functions. The movements and object manipulation tasks that replicate common situations in everyday living will then be used to control and play any computer game, making practice challenging and engaging. The ongoing study is a 6-week, single-center, parallel-group, equally allocated and assessor-blinded pilot randomized controlled trial. Thirty people with rheumatoid arthritis or osteoarthritis affecting the hand will be randomized to receive either conventional hand exercises or the task-oriented training. The purpose is to determine a preliminary estimation of therapeutic effectiveness and feasibility of the task-oriented training program. Performance based and self-reported hand function, and exercise compliance are the study outcomes. Changes in outcomes (pre to post intervention) within each group will be assessed by paired Student t test or Wilcoxon signed-rank test and between groups (control versus experimental) post intervention using unpaired Student t test or Mann-Whitney U test. The study findings will inform decisions on the feasibility, safety and completion rate and will also provide preliminary data on the treatment effects of the task

    Full Text Available Objectives : The aim was to assess of the morphology, intensity, and activity of changes in the first ultrasonographic (US examination of hands and feet in patients with early arthritis (lasting up to 12 months who were ultimately diagnosed with rheumatoid arthritis (RA. An attempt was made to demonstrate a correlation between the intensity of lesions in US and selected laboratory parameters. Material and methods : Ultrasonographic examination was performed using a LOGIC GE 500 device on a group of 60 patients with arthritis (46 women, 14 men aged 18–80, previously untreated. In total, 3120 hand and feet joints were examined. The assessment focused on the presence of joint effusion, synovial proliferation and power Doppler signals (assessed on a semi-quantitative scale. Each patient underwent laboratory tests, necessary for making a diagnosis. In order to analyze the correlations between changes in US and laboratory parameters, erythrocyte sedimentation rate (ESR, reactive protein test (CRP, rheumatoid factor (RF, and anti-citrullinated protein antibodies (ACPAs were used. Results : In the study group, the average duration of arthritis symptoms until the first US examination was 5.6 months. Among the 3120 examined hand and foot joints, deviations from the norm appeared in 1093 joints, synovial hypertrophy was found in 471 joints (grade 1 synovial hypertrophy was reported most frequently, while presence of signal in Power Doppler was revealed in 261 joints (grade 1 was observed most frequently. A statistically significant correlation was found between the intensity of changes in Power Doppler and CRP concentration. Conclusions : In patients with increased concentrations of CRP, we may expect arthritis of higher intensity, therefore, in order to prevent the progression of destructive changes, it is necessary to quickly implement effective disease-modifying antirheumatic treatment. The conducted research showed that the activity of joint

    The knee joints of 15 patients afflicted with rheumatoid arthritis were investigated using the method of nmr imaging. Parameters of investigation were the spin-echo and fast-field-echo sequences as well as the MR signal behaviour of proliferative synovial changes following intravenous administration of gadolinium dtpa. Pannus having formed on the articular surfaces or beneath the articular cartilages was distinguishable from other changes on the basis of the increased signal intensities to be observed after gadolinium dtpa had been given.

    Full Text Available Objective: Hospitalization process causes a variety of physical problems. The decrease of hand use in daily life during hospitalization brings hand dysfunction to mind in inpatients. The aim of this study is to compare the hand functions of hospitalized patients with Rheumatoid Arthritis (RA to outpatients in detail. Methods: Grip and pinch strengths of both hospitalized patients in rheumatology service and outpatients on the routine control day were measured. In addition, 9-Hole Peg Test was performed and the disability level was determined by the Turkish version of Michigan Hand Outcomes Questionnaire (MHOQ. Results: While grip strength and MHOQ scores were similar (p>0.05 in both groups, all three pinch strengths (lateral, bipod, tripod and 9HPT scores were lower (p<0.05 in hospitalized patients. Conclusion: Consequently, besides disease activity, hospitalization process also impairs fine hand functions in rheumatological patients. Evaluation of fine hand functions and appropriate rehabilitative interventions may prevent further disability in hospitalized patients. J Clin Exp Invest 2015; 6 (3: 228-232

    Pulmonary complications are frequent in patients with collagen vascular diseases (CVD). Frequent causes are a direct manifestation of the underlying disease, side effects of specific medications and lung infections. The standard radiological procedure for the work-up of pulmonary pathologies in patients with CVD is multidetector computed tomography (MDCT) with thin-slice high-resolution reconstruction. The accuracy of thin-slice CT for the identification of particular disease patterns is very high. The pattern of usual interstitial pneumonia (UIP) representing the direct pulmonary manifestation of rheumatoid arthritis (RA) can be identified with a sensitivity of 45 % and a specificity of 96 %. Both direct pulmonary manifestations, drug-induced toxicity and certain infections can have a similar appearance in thin-slice MDCT in various forms of CVD. Knowledge of the patterns and causes contributes to the diagnostic certainty. At first diagnosis of a CVD and associated pulmonary symptoms thin-slice MDCT is recommended. Clinical, lung function and imaging follow-up examinations should be performed every 6-12 months depending on the results of the MDCT. In every case the individual CT morphological patterns of pulmonary involvement must be identified. The combination of information on the anamnesis, clinical and imaging results is a prerequisite for an appropriate disease management. (orig.)

    The aim of this study was to establish the prevalence of tenosynovitis affecting the interosseous tendons of the hand in a rheumatoid arthritis (RA) population and to assess for association with metacarpophalangeal (MCP) joint synovitis, flexor tendon tenosynovitis or ulnar drift. Forty-four patients with RA underwent hand MRI along with 20 normal controls. Coronal 3D T1 VIBE sequences pre- and post-contrast were performed and reconstructed. The presence of interosseous tendon tenosynovitis was recorded alongside MCP joint synovitis, flexor tendon tenosynovitis and ulnar drift. Twenty-one (47.7 %) patients with RA showed interosseous tendon tenosynovitis. Fifty-two (14.8 %) interosseous tendons showed tenosynovitis amongst the RA patients. Interosseous tendon tenosynovitis was more commonly seen in association with adjacent MCP joint synovitis (p < 0.001), but nine MCP joints (5.1 %) showed adjacent interosseous tenosynovitis in the absence of joint synovitis. Interosseous tendon tenosynovitis was more frequently seen in fingers which also showed flexor tendon tenosynovitis (p < 0.001) and in patients with ulnar drift of the fingers (p = 0.01). Tenosynovitis of the hand interosseous tendons was found in 47.7 % of patients with RA. In the majority of cases this was adjacent to MCP joint synovitis; however, interosseous tendon tenosynovitis was also seen in isolation. (orig.)

    The purpose of this article is to compare tomosynthesis with radiography and MRI of the wrist and hand for evaluating bone erosion in patients with rheumatoid arthritis (RA). Twenty consecutive patients with an established diagnosis of RA and five control patients were included in this study. They underwent radiography, tomosynthesis, and MRI of the bilateral hand and wrist within a week. The mean total dose of radiography and tomosynthesis was 0.13 and 0.25 mGy, respectively. MRI evaluation was performed according to the Outcome Measures in Rheumatology Clinical Trials recommendations. Bone erosion on images from the three modalities was independently reviewed by two certificated radiologists with a 4-point scale (0, normal; 1, discrete erosion; 2, tomosynthesis, and MRI were 26.5%, 36.1%, and 36.7%, respectively. Significantly more bone erosions were revealed with tomosynthesis and MRI than with radiography (p tomosynthesis. Interobserver agreement (kappa value) for bone erosion was good to excellent on tomosynthesis and MRI for all joints (0.65-1.00 and 0.68-1.00, respectively), whereas it was slight to fair on radiography for some carpal bones and bases of metacarpal bones (0.22-0.56). Tomosynthesis is superior to radiography and almost comparable to MRI for the detection of bone erosion in patients with RA.

    Radiology plays a key role when the indications for arthroplasties of the hand and finger joints are determined and for the postoperative follow-up. On the one hand, the degree of inflammatory changes in all affected compartments is to be evaluated and graded; on the other hand, conventional radiograms allow for a first assessment of possible joint instability and impaired biomechanics. Both aspects influence the choice of the proper surgical therapeutic strategy. Osteolysis, deformity, fracture, prosthesis loosening or failure, heterotopic ossification, and foreign body-associated formation of granulation tissue are complications which can be detected on follow-up radiographs early on. (orig.) [German] Bei der Indikationsstellung und Verlaufskontrolle von Arthroplastien der Hand kommt der Radiologie eine wesentliche Rolle zu. Einerseits ist das Ausmass der entzuendlichen Veraenderungen in allen Kompartimenten umfassend zu beurteilen und graduieren, andererseits lassen sich bereits im konventionellen Roentgenbild Rueckschluesse auf etwaige Instabilitaet oder gestoerte Biomechanik ziehen. Beide Aussagen wirken sich auf die operative Therapieentscheidung massgeblich aus. Osteolyse, Deformitaet, Fraktur, Implantatlockerung oder -versagen, heterotope Knochenneubildung und fremdkoerperassoziierte Granulationsgewebebildung sind Komplikationen, die in den postoperativen Verlaufskontrollen fruehzeitig erfasst werden koennen.

    Time transfer using global navigation satellite system (GNSS) is a primary method of remote atomic clock comparisons. As of today, there are four operational GNSS systems, namely GPS, GLONASS, Galileo and BeiDou Navigation Satellite System (BDS or BeiDou). All of them can continuously provide position, navigation and time services. This paper mainly focuses on the progress of BeiDou time transfer at the National Time Service Center, Chinese Academy of Sciences (NTSC). In order to realize the BeiDou common view (CV) time comparison, we developed the Rinex2CGGTTS software according to the guidelines of the Common GNSS Generic Time Transfer Standard, Version 2E (CGGTTS V2E). By comparing the solutions of the Rinex2CGGTTS software to the solutions of the sbf2cggtts software provided by the manufacturer of our multi-GNSS receiver, we found the sbf2cggtts (version 1.0.5) solutions contained biases in measurements to different BeiDou satellites. The biases are most likely caused by sbf2cggtts’ timing group delay corrections in data processing. The noise of the observation data is analyzed by code multipath and common clock difference. Finally, the BeiDou CV results are compared to the GPS/GLONASS/Galileo CV results between NTSC and three European UTC(k) laboratories, including Royal Observatory of Belgium (ORB), Real Institute y Observatory de la Armada (ROA), Research Institutes of Sweden (RISE or SP). For the comparisons of each baseline, we aligned the BeiDou/Galileo/GLONASS links to the calibrated GPS link with the double-difference method. The results show that the performance of BeiDou CV is correlated to the number of BeiDou satellites available in common view. With the current BeiDou constellation, the standard deviation of the differences between all BeiDou CV satellites averaging result and the GPS PPP result is 2.03 ns, 2.90 ns and 4.06 ns for ORB-NTSC, SP-NTSC and ROA-NTSC links respectively.

    A series of patients with clinically early inflammatory joint disease due to rheumatoid arthritis, psoriatic arthritis and Reiter's syndrome were examined by plain film radiography and magnetic resonance imaging (MRI). The spin echo T1-weighted precontrast, T2-weighted, and, especially, T1-weighted postcontrast images demonstrated distinct differences in the distribution of inflamatory changes, both within and adjacent to involved small hand joints. Two major subtypes of inflammatory arthritis were shown, thus providing a specific differential diagnosis between rheumatoid arthritis and some patients with seronegative spondyloarthritis. In particular, all the patients with Reiter's syndrome who were studied, and half of those with psoriatic arthritis, had a distinctive pattern of extra-articular desease involvement. The need for a new classification of clinical subsets in psoriatic arthritis has been recently suggested. The present findings suggest that magnetic resonance imaging could be useful in such a reclassification of seronegative spondyloarthritis, as well as offering considerable potential for a reappraisal of pathogenesis and therapy. In this series, it was also noted that juxta-articular osteoporosis on plain film did not correlate with bone marrow oedema on MRI. Hence the aetiology of this common radiographic finding also merits further consideration. (orig.)

    Objective: In this prospective study, the time to remission after radiosynovectomy (RSV) was analyzed and the influence of age, sex, underlying disease, type of joint, and duration of illness on the success rate of RSV was determined. Methods: A total number of 57 patients with rheumatoid arthritis (n = 33) and arthrosis (n = 21) with a total number of 130 treated joints (36 knee, 66 small and 28 medium-size joints) were monitored using visual analogue scales (VAS) from one week before RSV up to four to six months after RSV. The patients had to answer 3 times daily for pain intensity of the treated joint. The time until remission was determined according to the Kaplan-Meier survivorship function. The influence of the prognosis parameters on outcome of RSV was determined by multivariate discriminant analysis. Results: After six months, the probability of pain relief of more than 20% amounted to 78% and was significantly dependent on the age of the patient (p = 0.02) and the duration of illness (p = 0.05), however not on sex (p = 0.17), underlying disease (p = 0.23), and type of joint (p = 0.69). Conclusion: Irrespective of sex, type of joint and underlying disease, a measurable pain relief can be achieved with RSV in 78% of the patients with synovitis, whereby effectiveness is decreasing with increasing age and progress of illness.

    Contrast-enhanced MRI is of value in assessing rheumatoid pannus in the hand, but the images are not always easy to quantitate. To develop and evaluate an improved measurement of volume of enhancing pannus (VEP) in the hand in human rheumatoid arthritis (RA). MR images of the hand and wrist were obtained for 14 patients with RA at 0, 1 and 13 weeks. Volume of enhancing pannus was measured on images created by subtracting precontrast T1-weighted images from contrast-enhanced T1-weighted images using a shuffle transformation technique. Maximum intensity projection (MIP) and 3D volume rendering of the images were used as a guide to identify the pannus and any contrast-enhanced veins. Visualisation of pannus was much improved following the shuffle transform. Between 0 weeks and 1 week, the mean value of the within-subject coefficient of variation (CoV) was 0.13 and the estimated total CoV was 0.15. There was no evidence of significant increased variability within the 13-week interval for the complete sample of patients. Volume of enhancing pannus can be measured reproducibly in the rheumatoid hand using 3D contrast-enhanced MRI and shuffle transform.

    Rheumatoid arthritis is a common disabling form of arthritis that frequently affects the hands and feet. With time, the majority of affected individuals will become disabled. Sixty-nine consecutively selected mild to moderately affected individuals with rheumatoid arthritis provided demographic data and agreed to complete the Short Musculoskeletal Function Assessment (SFMA) instrument. Focus group subjects selectively used minimally adaptive nonprescription footwear. Control subjects had similar disease expression, but did not alter their choice of footwear due to their disease. Adult patients with rheumatoid arthritis demonstrate a significant negative impact on their quality of life with mild or moderate disease expression, as evidenced by poor scores in all six domains of the SFMA. Subjects who used even mildly adaptive nonprescription footwear demonstrated a statistically significant negative impact in mobility (p expression. Focus subjects also demonstrated a trend to less favorable scores in the arm and hand domain. Mean scores of the daily activity, emotional status, and bother index domains fared worse than population norms, but there was no statistical difference between subjects using, or not using, adaptive footwear. Individuals affected with mild to moderate rheumatoid arthritis are disabled as compared with the general population. There is a severe negative impact on mobility and functional capacity when the disease process begins to affect their feet.

    Full Text Available Krankheitsbedingte Artefakte können bei der SpA (Spondylitis ankylosans; Mb. Bechterew die Sensitivität einer Knochendichtemessung im Lumbalbereich beeinträchtigen. Das bei dieser rheumatischen Erkrankung bekannte Osteoporoserisiko ist neben genetischen Faktoren und Entzündungsmechanismen auch von verschiedenen exogenen Einflüssen abhängig. An 47 SpA-Patienten wurde mittels DEXA eine vergleichende Knochendichtemessung (BMD an der Hüfte (Schenkelhals und Ward'sches Dreieck sowie im Bereich der Wirbelsäule (L1-L4 vorgenommen. Zusätzlich erfolgte eine Erhebung der Lebens-Ernährungsgewohnheiten der SpA-Patienten in bezug auf die BMD, um exogene Einflüsse erfassen zu können. Die Knochendichtemessungen ergaben an der LWS wesentlich häufiger eine BMD im Normbereich als am proximalen Femur. Besonders deutliche Unterschiede traten im höheren Lebensalter auf, bei dem aufgrund von Kalzifizierungsvorgängen und Syndesmophyten an der LWS fälschlicherweise eine Dichtezunahme vorgetäuscht wird. Es kann daher bei SpA empfohlen werden, die wesentlich sensitivere Dichtemessung am Schenkelhals durchzuführen. Die über einen Zeitraum von 3 Jahren beobachteten, signifikant erhöhten, medianen CRP-Spiegel zeigen, daß eine permanente Aktivierung von Entzündungsprozessen bei SpA auch einen negativen Faktor betreffend des Knochenmasseverlustes darstellt. Die Analyse der Lebensgewohnheiten ergab, daß SpA-Patienten mit normaler BMD ausnahmslos regelmäßig kalziumreiche Nahrungsmittel zu sich nehmen; bei verminderter BMD wurde in der Mehrheit ein fehlender Konsum an Milchprodukten beobachtet. Leider war auch mit abnehmender BMD eine Verminderung der bei SpA empfohlenen Bewegungsübungen festzustellen. Aufgrund der Resultate ergibt sich eine generelle Empfehlung zu regelmäßigen Bewegungsübungen plus Osteoporosediät bei allen Bechterew-Patienten.

    Full Text Available Global Navigation Satellite System (GNSS-based positioning is experiencing rapid changes. The existing GPS and the GLONASS systems are being modernized to better serve the current challenging applications under harsh signal conditions. These modernizations include increasing the number of transmission frequencies and changes to the signal components. In addition, the Chinese BeiDou Navigation Satellite system (BDS and the European Galileo are currently under development for global operation. Therefore, in view of these new upcoming systems the research and development of GNSS receivers has been experiencing a new upsurge. In this article, the authors discuss the main functionalities of a GNSS receiver in view of BDS. While describing the main functionalities of a software-defined BeiDou receiver, the authors also highlight the similarities and differences between the signal characteristics of the BeiDou B1 open service signal and the legacy GPS L1 C/A signal, as in general they both exhibit similar characteristics. In addition, the authors implement a novel acquisition technique for long coherent integration in the presence of NH code modulation in BeiDou D1 signal. Furthermore, a simple phase-preserved coherent integration based acquisition scheme is implemented for BeiDou GEO satellite acquisition. Apart from the above BeiDou-specific implementations, a novel Carrier-to-Noise-density ratio estimation technique is also implemented in the software receiver, which does not necessarily require bit synchronization prior to estimation. Finally, the authors present a BeiDou-only position fix with the implemented software-defined BeiDou receiver considering all three satellite constellations from BDS. In addition, a true multi-GNSS position fix with GPS and BDS systems is also presented while comparing their performances for a static stand-alone code phase-based positioning.

    Full Text Available Rheumatoid arthritis’ synovitis affects mostly small hand and feet joints, although it may compromise any joint with a synovial lining. Cervical involvement occurs usually in longstanding disease in over half of these patients. We report the case of a 35-year old male patient who was referred to our outpatient clinic for a 2-year severe and disabling inflammatory neck pain, with incomplete response to intramuscular non-steroidal anti-inflammatory drugs and unremarkable cervical imaging studies. He also mentioned self-limited episodes of symmetric polyarthralgia involving hands, wrists, elbows, knees and feet, which started after his cervical complaints. On laboratorial workup, positive rheumatoid factor and anti-citrullinated peptide antibody and negative HLA-B27 were found. Cervical spine magnetic resonance imaging revealed atlantoaxial subluxation and odontoid process inflammatory pannus and erosions. Rheumatoid arthritis with cervical spine involvement as initial manifestation of disease was the definite diagnosis. The patient was started on methotrexate and prednisone and he was referred to neurosurgery outpatient clinic for cervical spine fixation.

    2016-02-01

    Full Text Available A new method for estimating the BeiDou inter-frequency satellite clock bias is proposed, considering the shortage of the current methods. The constant and variable parts of the inter-frequency satellite clock bias are considered in the new method. The data from 10 observation stations are processed to validate the new method. The characterizations of the BeiDou inter-frequency satellite clock bias are also analyzed using the computed results. The results of the BeiDou inter-frequency satellite clock bias indicate that it is stable in the short term. The estimated BeiDou inter-frequency satellite clock bias results are molded. The model results show that the 10 parameters of model for each satellite can express the BeiDou inter-frequency satellite clock bias well and the accuracy reaches cm level. When the model parameters of the first day are used to compute the BeiDou inter-frequency satellite clock bias of the second day, the accuracy also reaches cm level. Based on the stability and modeling, a strategy for the BeiDou satellite clock service is presented to provide the reference of our BeiDou.

    1994-01-01

    Plain films of the calcanea of 768 patients with confirmed rheumatoid arthritis were examined retrospectively with reference to inflammatory rheumatic changes. 42 patients (5.5%) showed an erosion of the posterior upper calcaneal margin related to an Achilles bursitis. In three patients there were additional plantar erosions. The Achilles bursitis was bilateral in 50% of cases, particularly in patients in stages 2 and 3 according to Steinbrocker. In the majority of bilateral cases (62%) the size or shape of the lesions was asymmetrical. Our observations indicate that involvement of the os calcis is not uncommon in rheumatoid arthritis; routine examination of this bone would appear to be indicated even in patients without symptoms. Since the defect is unilateral in half the patients, unilateral occurrence of an erosive lesion cannot be regarded as a criterion for a bacterial-inflammatory bursitis. Contrary to the symmetrical involvement of joints in the hands in rheumatoid arthritis, defects in the calcanea are often unilateral or asymmetrical. (orig.) [de

    Plain X-ray films including some special radiographic views are still the basis of the radiological evaluation of injuries of the distal forearm, the wrist, and the hand. Especially, in the diagnosis of fractures of the distal radius the exact positioning of the arm and hand is essential. For the description of fractures of the distal forearm the AO classification of fractures should be used, which is comprehensive and universally applicable. Conventional tomography and computed tomography (CT) of the radio-ulnar joint and the wrist are used in patients with persisting complaints or equivocal findings on plain radiographs, and difficult anatomical situations. Suspected ligamentous injuries of the wrist including tears of the triangular fibrocartilage complex (TFCC) are evaluated by wrist arthrography or magnetic resonance imaging (MRI), the latter requiring a highly skilled imaging and interpretation technique. MRI is the method of choice for the detection of osteonecrosis. Ultrasound examinations are of minor importance in the work up of wrist and hand injuries. (orig.)

    In staging cancer of the urinary bladder, the kidneys and the prostate and of testicular cancer there is a need for detecting tumor involvement of the lymph nodes to avoid surgical exploration. Positron emission tomography (PET) using fluorodeoxyglucose (FDG) can detect tumorous lymph nodes (sensitivity: 70%, specificity: 85%) which is helpful for several patients. In carcinoma of the prostate, other radiotracers than FDG (e.g. C-11-choline) might be more sensitive to detect tumorous lymph nodes. Up to now no diagnostical benefit of PET in germ cell tumors could be demonstrated in the published small series. In principle FDG-PET is useful in diagnosis of recurrence. In germ cell cancer FDG-PET seems to identify effectively persistent vital tumor tissue after chemotherapy. A multicenter study was initiated to demonstrate the potential of FDG-PET in a sufficient number of patients with germ cell tumor. (orig.) [German] Bei Harnblasen-, Nieren-, Prostata- und Hodenkarzinomen besteht aus klinischer Sicht ein Bedarf an verbessertem Lymphknoten-Staging, um die operative Evaluation zu vermeiden. Die Positronenemissionstomographie (PET) mit Fluordeoxyglukose (FDG) kann daher im Einzelfall bei Harnblasen- und Nierenkarzinomen hilfreich sein (bei Sensitivitaet um 70% und Spezifitaet um 85%). Beim Prostatakarzinom koennten sich andere Radiotracer (z.B. C-11-Cholin) bei der Detektion von tumoroesen Lymphknoten ueberlegen erweisen. Bei Keimzelltumoren konnte ein Nutzen der PET im primaeren Staging bei den bisher publizierten kleinen Studien nicht nachgewiesen werden. Fuer die Rezidivdiagnostik ist bei den genannten Tumoren aus grundsaetzlicher Ueberlegung der Einsatz von DFG-PET sinnvoll. Die Erkennung von vitalem malignen Tumorgewebe nach Chemotherapie erscheint bei Keimzelltumoren mit FDG-PET weitgehend sicher zu gelingen. Eine multizentrische Studie wurde begonnen, die hierueber Aufschluss geben wird. (orig.)

  18. The method for objective evaluation of the intensity of radial bone lesions in rheumatoid arthritis using digital image analysis

    The semiquantitative methods used in everyday diagnostic practice for scoring the intensity of bone lesions in rheumatoid arthritis are susceptible to a subjective error. The paper describes the original algorithm for an image analysis as a method for quantitative and objective evaluation of the intensity of radiological lesions in rheumatoid arthritis. 75 plain radiograms of the hand of patients diagnosed with rheumatoid arthritis, in various stages of bone pathology, were evaluated. The analysis focused on the signs of pathological rebuilding of the affected bone, especially in the distal epiphysis of the radial bone. The plain radiograms of the hand were digitally analysed based on the modified method, formerly used for quantitative assessment of bone trabeculation. The method allowed us to objectively verify various scoring systems of radiograms widely used in rheumatological diagnosis. (author)

    The use of artificial joint implants has risen greatly over the past years. However, few investigations of the cancer risk associated with implants have been performed. We investigated cancer risk in patients with finger and hand joint and temporo-mandibular (TMJ) joint implants. A nationwide cohort in Denmark of patients with finger and hand joint prostheses (n = 858) or TMJ implants (n = 389) was followed from January 1, 1977, to December 31, 1995, to evaluate any potential cancer risks subsequent to receiving these implants. Standardized incidence ratios (SIRs) for all cancers were 1.0 (95% CI = 0.8-1.2) for the finger and hand joint cohort and 1.1 (95% CI = 0.8-1.7) for the TMJ cohort. A significant risk for non-Hodgkin's lymphoma was found in the finger and hand joint cohort (SIR = 3.8, 95% CI = 1.5-7.8). When the finger and hand joint cohort was stratified by diagnosis of rheumatoid arthritis, the excess risk was seen only in the group with rheumatoid arthritis. This is consistent with past studies, which have found an association between rheumatoid arthritis and non-Hodgkin's lymphoma. Our results provide evidence that the cancer risk for patients with finger and hand joint prostheses and TMJ implants is similar to that for the general population.

    The successful launch of five new-generation experimental satellites of the China's BeiDou Navigation Satellite System, namely BeiDou I1-S, I2-S, M1-S, M2-S, and M3-S, marks a significant step in expanding BeiDou into a navigation system with global coverage. In addition to B1I (1561.098 MHz) and B3I (1269.520 MHz) signals, the new-generation BeiDou-3 experimental satellites are also capable of transmitting several new navigation signals in space, namely B1C at 1575.42 MHz, B2a at 1176.45 MHz, and B2b at 1207.14 MHz. For the first time, we present an initial characterization and performance assessment for these new-generation BeiDou-3 satellites and their signals. The L1/L2/L5 signals from GPS Block IIF satellites, E1/E5a/E5b signals from Galileo satellites, and B1I/B2I/B3I signals from BeiDou-2 satellites are also evaluated for comparison. The characteristics of the B1C, B1I, B2a, B2b, and B3I signals are evaluated in terms of observed carrier-to-noise density ratio, pseudorange multipath and noise, triple-frequency carrier-phase ionosphere-free and geometry-free combination, and double-differenced carrier-phase and code residuals. The results demonstrate that the observational quality of the new-generation BeiDou-3 signals is comparable to that of GPS L1/L2/L5 and Galileo E1/E5a/E5b signals. However, the analysis of code multipath shows that the elevation-dependent code biases, which have been previously identified to exist in the code observations of the BeiDou-2 satellites, seem to be not obvious for all the available signals of the new-generation BeiDou-3 satellites. This will significantly benefit precise applications that resolve wide-lane ambiguity based on Hatch-Melbourne-Wübbena linear combinations and other applications such as single-frequency precise point positioning (PPP) based on the ionosphere-free code-carrier combinations. Furthermore, with regard to the triple-frequency carrier-phase ionosphere-free and geometry-free combination, it is found

    Full Text Available Bei malignen Erkrankungen, wie dem Mammakarzinom, dem Prostatakarzinom, dem Bronchialkarzinom oder dem multiplen Myelom ist der Knochen eines der am häufigsten von Metastasen betroffenen Organe. Das klinische Beschwerdebild ist durch das Auftreten pathologischer Frakturen, Schmerzen und Hyperkalzämien gekennzeichnet. Eine erhöhte Knochenresorptionsrate und Verlust an Knochenmasse im Sinne von osteoporoseartigen Veränderungen bedingt durch eine inadäquat überschießende Osteoklastendifferenzierung und -aktivierung sind ursächlich dafür verantwortlich. Durch jüngst publizierte Ergebnisse diverser Studien und Untersuchungen konnten die genauen Mechanismen der Rekrutierung und Aktivierung von Osteoklasten weiter aufgeklärt werden. Receptor activator of nuclear factor-kappa-B ligand (RANKL, ein Mitglied der Tumor necrosis factor (TNF Superfamilie konnte als entscheidender Faktor in der Osteoklastengenese identifiziert werden. Die Interaktion von RANKL mit seinem Rezeptor RANK (receptor activator of nuclear factor-kappa-B induziert die Entwicklung der osteoklastären Reihe aus dem hämatopoetischen Kompartment und fördert weiters die Differenzierung zu Osteoklastenvorstufen und die Aktivierung reifer Osteoklasten, ebenso wird eine verzögert einsetzende Apoptose bewirkt. Neben RANK und RANKL ist Osteoprotegerin (OPG als dritte Komponente in der Regulation der Knochenresorption involviert. Als Mitglied der TNF-Superfamilie bindet OPG an RANKL und blockiert somit alle stimulierenden Effekte von RANK auf die Osteoklastenentwicklung und neutralisiert so alle biologischen Effekte von RANKL. Diverse Hormone und Zytokine üben durch die Modifikation der Ratio von RANKL zu OPG einen regulatorischen Effekt auf die Knochenresorption aus. Diese ist bei osteolytischen Knochenmetastasen, beim multiplen Myelom und bei der malignen Hyperkalzämie erhöht. Das Gleichgewicht knochenaufbauender wie -abbauender Mechanismen scheint somit durch die Ratio von

    Long since it have been suggested that a subpopulation of patients with rheumatoid arthritis, diagnosed with negative rheumatoid factor tests, represents a clinical entity quite distinct from that of seropositive rheumatoid arthritis (RA). Our aim was to establish a scientific comparative analysis between seronegative and seropositive rheumatoid arthritis, regarding some radiological and clinical parameters, applied for the first time on patients from Kosovo. Two hundred fifty patients with rheumatoid arthritis according to the American College of Rheumatology criteria were retrospectively studied by analysis the radiographic damage and clinical parameters of the disease, using a data base. All examinees were between 25-60 years of age (Xb=49.96, SD=10.37) with disease duration between 1-27 years (Xb = 6.41, SD=6.47). All patients underwent a standardised evaluation radiographs. Baseline standardised poster anterior radiographs of hands and feet and radiographs of other joints, depending on indications, were assessed. Erythrocyte sedimentation rate values correlated with the radiological damages and statistical difference was found for seronegative subset (r=0.24, p<0.01). Longer duration of the disease resulted in the increase of radiological changes in both subsets (r=0.66, p<0.01) seronegative, (r=0.49, p<0.01) seropositive. Anatomic changes of IInd and IIIrd level were nearly equally distributed in both subsets, 76 (60.8%) seronegative, 75 (60%) seropositive. Radiological damages are nearly equal in both subsets, elevate in relation to the duration of the disease and correlate with ESR values. Regarding the sero-status, differences within sex, with some exceptions, are not relevant. Although there are some definite quantitative and qualitative differences regarding sero-status, obviously there is a great deal of overlap between the two groups.

    Rheumatoid arthritis is a systemic disorder where clinically significant renal involvement is relatively common. However, crescentic glomerular nephritis is a rarely described entity among the rheumatoid nephropathies. We report a case of a patient with rheumatoid arthritis presenting with antineutrophil cytoplasmic antibody-negative crescentic glomerular nephritis. A 54-year-old Sri Lankan woman who had recently been diagnosed with rheumatoid arthritis was being treated with methotrexate 10 mg weekly and infrequent nonsteroidal anti-inflammatory drugs. She presented to our hospital with worsening generalized body swelling and oliguria of 1 month's duration. Her physical examination revealed that she had bilateral pitting leg edema and periorbital edema. She was not pale or icteric. She had evidence of mild synovitis of the small joints of the hand bilaterally with no deformities. No evidence of systemic vasculitis was seen. Her blood pressure was 170/100 mmHg, and her jugular venous pressure was elevated to 7 cm with an undisplaced cardiac apex. Her urine full report revealed 2+ proteinuria with active sediment (dysmorphic red blood cells [17%] and granular casts). Her 24-hour urinary protein excretion was 2 g. Her serum creatinine level was 388 μmol/L. Abdominal ultrasound revealed normal-sized kidneys with acute parenchymal changes and mild ascites. Her renal biopsy showed renal parenchyma containing 20 glomeruli showing diffuse proliferative glomerular nephritis, with 14 of 20 glomeruli showing cellular crescents, and the result of Congo red staining was negative. Her rheumatoid factor was positive with a high titer (120 IU/ml), but results for antinuclear antibody, double-stranded deoxyribonucleic acid, and antineutrophil cytoplasmic antibody (perinuclear and cytoplasmic) were negative.

    Full Text Available Rheumatoid arthritis (RA is a chronic inflammatory disease in which pro-inflammatory cytokines, including tumor necrosis factor (TNF-alpha, play a crucial role. The chronic inflammation, combined with reduced physical activity, leads to muscle wasting whereas fat mass would be maintained; the resulting abnormal metabolic state is described as rheumatoid cachexia. Since the loss of muscle volume would be compensated by the increased fat mass, body mass index (BMI is reported not to reflect the nutritional status in RA patients. The implication of rheumatoid cachexia for cardiovascular risk and clinical prognosis is not clearly understood, however, adequate control of disease activity in combination with appropriate physical exercise could be the most important strategy to control rheumatoid cachexia and related metabolic problems.

Apos essa incursão pelo campo filosófico, será aduzido um dos trabalhos de D. R. Scott, ex-professor da Universidade de Michigan, que já na década de 1930 defendia o processo de raciocínio dedutivo e a necessidade de coerência e unidade para o estabelecimento dos princípios contábeis. Este estudo justifica-se, principalmente, porque ainda existem pesquisadores da área contábil que defendem o método indutivo com único procedimento cientifico capaz de levar a certeza, Como defendia Descartes. Alem disso, mesmo apos a revolução cientifica princípios teóricos de Newton, pelos princípios da teoria da relatividade de Einstein, alguns pesquisadores defendem a imutabilidade dos princípios contábeis, como sendo verdades indubitáveis, não aceitando o permanente desenvolvimento da teoria contábil e sua continua adaptabilidade a nova realidade ambiental. A contabilidade, assim como toda disciplina do conhecimento humano que postula um patamar cientifico, deve estruturar-se com base em um conjunto de princípios racionalmente dispostos. Diante desse panorama, faz-se mister inquirir se os princípios contábeis podem ser oniscientes e impassíveis as mudanças do mundo?

    Pulmonary infections are a common complication in immunosuppressed patients with a frequently fatal prognosis despite modern prophylactic therapy. An early and correct diagnosis is important for initiation of the appropriate therapy. Chest radiography is the preferred initial imaging examination but is not accurate enough for the detection of pulmonary infections in immunosuppressed patients. Pneumonia is caused by a broad spectrum of pathogens in immunocompromised patients. In addition to imaging, the clinical history and epidemiology also play an important role in the diagnostics. Using epidemiological and anamnestic information, computed tomography (CT) shows a significantly better sensitivity and specificity particularly for the diagnosis of atypical forms of pneumonia. Due to the exact imaging of the different infiltration patterns CT provides an increased sensitivity with respect to the etiological classification of pulmonary infections. This article reviews in particular the radiological findings of commonly occurring pulmonary infections in immunosuppressed patients. (orig.) [German] Pneumonien bei immunsupprimierten Patienten sind haeufige Komplikationen, die trotzt moderner Prophylaxe toedlich verlaufen koennen.

    Purpose: To evaluate the diagnostic performance of three-dimensional (3D) MR maximum intensity projection (MIP) in the assessment of synovitis of the hand and wrist in rheumatoid arthritis (RA) compared to 3D contrast-enhanced magnetic resonance imaging (CE-MRI). Materials and methods: Twenty-five patients with RA underwent MR examinations. 3D MR MIP images were derived from the enhanced images. MR images were reviewed by two radiologists for the presence and location of synovitis of the hand and wrist. The diagnostic sensitivity, specificity and accuracy of 3D MIP were, respectively, calculated with the reference standard 3D CE-MRI. Results: In all subjects, 3D MIP images yielded directly and clearly the presence and location of synovitis with just one image. Synovitis demonstrated high signal intensity on MIP images. The k-values for the detection of articular synovitis indicated excellent interobserver agreements using 3D MIP images (k = 0.87) and CE-MR images (k = 0.91), respectively. 3D MIP demonstrated a sensitivity, specificity and accuracy of 91.07%, 98.57% and 96.0%, respectively, for the detection of synonitis. Conclusion: 3D MIP can provide a whole overview of lesion locations and a reliable diagnostic performance in the assessment of articular synovitis of the hand and wrist in patients with RA, which has potential value of clinical practice.

    Tissue viability is of particular interest in acute cerebral ischemia because it may be preserved if reperfusion can be achieved rapidly, e.g. by acute thrombolysis. Measurements of regional cerebral blood flow (CBF) and oxygen consumption by PET can assess tissue viability, and they have substantially increased our knowledge of th pathophysiology of ischemic stroke and the associated penumbra. Widerspread clinical application in acute stroke, however, is unlikely because of the large logistic and personnel resources required. In chronic cerebrovascular disease, measurement of regional CBF and glucose metabolism, which is usually coupled, provide detailed insights in disturbance of cortical function, e.g. due to deafferentiation, and contribute to differentiation of dementia types. Chronic misery perfusion, i.e. reduced perfusion that does not match the metabolic demand of the tissue, can be demonstrated by PET. It may be found in some patients with high-grade arterial stenoses. Less severe impairment of brain perfusion can be demonstrated by measurement of the cerebrovascular reserve capacity. The most frequent clinical situations can be assessed by less demanding procedures, e.g. by SPECT. In conclusion, PET has its role in cerebrovascular disease primarily within scientific studies, where high resolution and absolute quantitation of physiological variables are essential.

    Full Text Available Osteoprotegerin (OPG wird in der entzündeten Synovialis bei chronischer Polyarthritis von Makrophagen, dendritischen Zellen und B-Zellen produziert. OPG hemmt die Differenzierung von Osteoklasten und ihre Aktivierung durch die Bindung an RANKL (receptor activator of NFkappaBbeta ligand. OPG könnte daher eine wichtige Rolle in der Verhinderung des Auftretens von Erosionen bei chronischer Polyarthritis spielen. In der vorliegenden Studie wurde untersucht, ob die Serumspiegel von Osteoprotegerin mit Entzündungsparametern oder der Gelenksdestruktion bei chronischer Polyarthritiskorrelieren. Patienten und Methoden: In 85 Sera von 68 Patienten mit chronischer Polyarthritis wurden die Serumspiegel von OPG untersucht und mit klinischen Parametern, Laborbefunden und dem Larsen-Score verglichen. Zur OPG-Bestimmung wurde ein Sandwich-ELISA (enzyme-linked-im-munosorbent-assay mit zwei spezifischen OPG-Antikörpern verwendet. Mit dem bindenden Antikörper wurde eine Mikrotiterplatte beladen, der zweite Biotin-konjugierte Antikörper wurde durch Streptavidin-Peroxidase und TMB gemessen. Der Immunoassay mißt sowohl freies als auch an RANKL gebundenes OPG. Zur statistischen Auswertung wurde ein SAS-Programm verwendet, als Tests wurden der Mann-Whitney-Test, die Spearman-Korrelation und die Varianzanalyse (ANOVA angewandt. Ergebnisse: Verglichen mit einer gesunden Kontrollgruppe (Alter 56-76 Jahre lagen die Mittelwerte von Serum-OPG bei chronischer Polyarthritis höher. Wenn man den Mittelwert der Gesunden für die Einteilung in höhere oder niedrigere Serum-OPG-Werte bei Patienten mit chronischer Polyarthritis verwendet, zeigt sich im Mann-Whitney-Test eine signifikante Korrelation nicht nur mit BSG und Rheumafaktor, sondern auch mit dem Larsen-Score. Die OPG-Spiegel korrelierten mit dem Rheumafaktor, der BSG und dem Serum-CRP (C-reaktives Protein signifikant positiv, der Larsen-Score zeigte nur einen statistischen Trend.

    R. M. Balabanova

    2018-01-01

    Full Text Available Due to the development of synovitis, early-stage hand osteoarthritis (HOA mimics hand joint injury in rheumatoid arthritis (RA. However, the topography of synovitis is diverse in these diseases:  distal interphalangeal and thumb joints are involved in the process in HOA. In the latter, tests are negative for immunological markers  (anti-cyclic citrullinated peptide antibodies, which is typical of RA.  The differences between HOA and RA are prominent, as evidenced  by hand X-rays and magnetic resonance imaging. Investigations  suggest that cytokine profile imbalance is implicated in the  pathogenesis of osteoarthritis, which brings it closer to RA. However, therapy for HOA has not been practically developed; there are only a few works on the use of disease-modifying antirheumatic drugs and  biological agents in these patients. It is necessary to work out Russian guidelines for the treatment of HOA.

    Rheumatoid arthritis is a relatively common multisystem disease associated with significant mortality and morbidity. Thoracic disease, both pleural and pulmonary, is a frequent extra-articular manifestation of rheumatoid arthritis and responsible for approximately 20% of rheumatoid-associated mortality. Rheumatoid disease and its associated therapies can affect all compartments of the lung inciting a range of stereotyped pathological responses and it is not infrequent for multiple disease entities to co-exist. In some instances, development of pulmonary complications may precede typical rheumatological presentation of the disease and be the first indication of an underlying connective tissue disease. The spectrum of thoracic disease related to rheumatoid arthritis is reviewed

    Biogenic emissions play a critical role in urban and regional air quality. For instance, biogenic emissions contribute upwards of 76% of the daily hydrocarbon emissions in the Atlanta, Georgia airshed. The Biogenic Emissions Inventory System-Version 2.0 (BEIS2) and the Biogenic Model for Emissions (BIOME) are two models that compute biogenic emissions estimates. BEIS2 is a FORTRAN-based system, and BIOME is an ARC/INFO{reg_sign} - and SAS{reg_sign}-based system. Although the technical formulations of the models are similar, the models produce different biogenic emissions estimates for what appear to be essentially the same inputs. The goals of our study are the following: (1) Determine why BIOME and BEIS2 produce different emissions estimates; (2) Attempt to understand the impacts that the differences have on the emissions estimates; (3) Reconcile the differences where possible; and (4) Present a framework for the use of BEIS2 and BIOME. In this study, we used the Coastal Oxidant Assessment for Southeast Texas (COAST) biogenics data which were supplied to us courtesy of the Texas Natural Resource Conservation Commission (TNRCC), and we extracted the BEIS2 data for the same domain. We compared the emissions estimates of the two models using their respective data sets BIOME Using TNRCC data and BEIS2 using BEIS2 data.

    Pemphigus vulgaris (PV) wird in der Regel mit systemischen Corticosteroiden und Immunsuppressiva behandelt. Avaskuläre Nekrose (AVN) des Hüftkopfes ist eine gut bekannte schwerere Komplikation einer Corticosteroid-Therapie. Die Charakteristika dieser schweren Komplikation bei PV sind nach wie vor unbekannt. Nicht kontrollierte, retrospektive Untersuchung aller PV-bedingten AVN-Fälle, die in einer iranischen Klinik für bullöse Autoimmunerkrankungen zwischen 1985 und 2013 diagnostiziert wurden. Anhand der Krankenakten von 2321 untersuchten PV-Patienten wurden 45 Fälle (1,93 %) von femoraler AVN identifiziert. Dreißig davon waren Männer. Das mittlere Alter bei der Diagnose der AVN betrug 47,4 ± 14,2 Jahre. Der mittlere Zeitraum zwischen der Diagnose des PV und dem Einsetzen der AVN lag bei 25,3 ± 18,3 Monaten. Mit Ausnahme von acht Fällen (17,8 %) setzte die AVN bei der Mehrheit der Patienten innerhalb von drei Jahren nach Diagnose des PV ein. Die mittlere kumulative Dosis von Prednisolon bei Patienten mit AVN betrug 13.115,8 ± 7041,1 mg. Zwischen der Prednisolon-Gesamtdosis und dem Zeitraum bis zum Einsetzen der AVN bestand eine starke Korrelation (p = 0,001). Bei Patienten mit Alendronateinnahme in der Vorgeschichte war dieser Zeitraum signifikant kürzer (p = 0,01). Die AVN ist eine schwere Komplikation einer Corticosteroid-Behandlung bei Patienten mit PV. Sie wird bei 2 % der Patienten beobachtet und tritt vor allem in den ersten drei Behandlungsjahren auf. Bei Patienten, die höhere Dosen von Prednisolon erhalten, setzt die AVN tendenziell früher ein. © 2016 Deutsche Dermatologische Gesellschaft (DDG). Published by John Wiley & Sons Ltd.

    One hundred and seventy-five cases of clinically diagnosed rheumatoid arthritis, 82 non-rheumatoid cases suffering from various other diseases and 40 healthy normal controls were investigated for detection of rheumatoid factor, quantitation of serum immunoglobulin, demonstration of antinuclear antibody (ANA) and LE cell phenomenon. Microlatex agglutination test of serum for rheumatoid factor (RF) showed 64% positivity in rheumatoid group and 1.2% positivity in non-rheumatoid group. All three immunoglobulins (IgG, IgM, IgA) were found to be raised in serum of patients with rheumatoid arthritis, whereas only IgA level was elevated in serum of patients with non-rheumatoid diseases. ANA and LE cell phenomenon were observed in 3.4% and 2.8% cases respectively in cases of clinically diagnosed rheumatoid arthritis who had been suffering from severe active rheumatoid arthritis. In non-rheumatoid group RF was positive in significant titre in only one case of leprosy. Synovial fluid and synovium were found to be heavily infiltrated by plasma cells and lymphocytes. RF appears first in synovial fluid and then in serum. Hence RF titre in blood may not attain significant level for the first several months.

    One hundred and twenty cases of clinically diagnosed rheumatoid arthritis, 80 non-rheumatoid cases suffering from various other diseases and 40 healthy individuals were investigated for the presence of rheumatoid factor, quantitation of serum immunoglobulin, demonstration of ANA and LE cell phenomenon. Microlatex agglutination test of serum for rheumatoid factor showed 56.6% positivity in rheumatoid group and 3.7% positivity in non-rheumatoid group. All three serum immunoglobulins (IgG, IgM, IgA) were raised in serum in significant titre in cases of rheumatoid arthritis, whereas only IgA lever was elevated in the group of non-rheumatoid diseases. ANA and LE cell phenomenon were observed in 11.7% and 4.4% cases of rheumatoid arthritis who had severe underlying disease. In non-rheumatoid group, only one of 6 cases of systemic lupus erythematosus showed rheumatoid factor and that too in an insignificant titre (less than 1:20). Synovium and synovial fluid contained plenty of plasma cells and lymphocytes. It has been observed that RF appears first in synovial fluid and it may take several months to a year to attain detectable level in serum.

    The study was conducted in order to investigate the effect of disease-related variables such as socio-demographic characteristics, disease complaints and use of necrosis factor (anti-TNF) on the body image and self-esteem in patients with rheumatoid arthritis. The data was collected by an Introductory Information Form, Body Image Scale (PfP) BIS and the Coopersmith Self-Esteem Inventory (SEI) in 120 patients with rheumatoid arthritis and in 120 healthy controls. One-way analysis of variance, Tukey HDS analysis, t-test, Kruskal-Wallis test, the Mann-Whitney U test, and Pearson's and Spearman's correlation coefficients were used to compare the data. 60% of the control group were in the 20-44 year-age group, 75% were women and 30.8% had a bachelor's degree or above, while 60% of patient group were in the 20-44 year-age group, 71.7% were women and 36.7% had a bachelor's degree or higher education level. We observed that the body satisfaction and self-esteem levels were higher in the 20-44 age group, in those with a bachelor's degree or higher education and in the patients who had no additional disease and who did not use anti-TNF. The body satisfaction and self-esteem levels were lower in those who had been receiving treatment for longer than 5 years, who had changes in hands and body, who had gait disturbance and who had changes in family and working life. The assessment of the psychosocial needs with a holistic approach and training programs for body image and self-esteem would be advisable for patients with rheumatoid arthritis who are aged 45-59 years, who have low self-esteem, who have additional diseases, who use anti-TNF, who have changes in hands and body and who have primary-school education.

    It has not been clear what kinds and how much nutrients could be harmful, preventive, or healthful for development of rheumatoid arthritis. This study aimed to determine the impact of dietary habits on the pathogenesis of rheumatoid arthritis. This case-control study was conducted on a total of 500 rheumatoid arthritis patients and 500 healthy controls refereed to three clinics of Shiraz University of Medical Sciences in 2015-2016. Convenience sampling was used for data collection in both case and control groups. An approved valid and reliable questionnaire including information about the intake of different kinds of beverages, and nutritious and non-nutritious diet was used. Data were analyzed by SPSS, version 20, using t test, chi-square and Multiple Logistic Regression model. The associations between rheumatoid arthritis development and variables including drinking 1-7 cups of coffee (OR = .44, CI .25-.76), ≥ 8 cups of coffee (OR = .50, CI .28-.90), full-fat milk (OR = 1.01, CI 1.003-1.03) per month, and intake of green tea (OR = .65, CI .45-.93) and solid oils (OR = 2.29, CI:1.57-3.34) were significant. Based on the findings, coffee consumption more than one cup per month and green tea might have preventive effects on developing rheumatoid arthritis. On the other hand, patients who consumed more full-fat milk per month and solid oil might be at risk of development of rheumatoid arthritis. Therefore, modification of diet based on these findings is suggested. Performing a cohort study to determine the causality effect of dietary habits and development and prevention of rheumatoid arthritis is recommended.

    Full Text Available Die Magnet-Resonanz-Urographie (MRU ist ein relativ neues Verfahren in der Diagnostik des oberen Harntraktes. Das Ziel dieser Studie war der Vergleich der Aussagefähigkeit der MRU unter Gabe von Gadolinium und Furosemid und dem konventionellen Urogramm (IVU in der Diagnostik der Ursache von Obstruktionen im Bereich des Harnleiters. 82 Patienten mit im IVU nachgewiesener Obstruktion des oberen Harntraktes oder urographisch stummer Niere bei sonographisch nachgewiesener Dilatation wurden der MRU zugeführt. Die Bilder beider Untersuchungsmethoden wurden von voneinander unabhängigen Untersuchern befundet. Zwei Urologen befundeten die IVU-Bilder, zwei Radiologen die MRU-Bilder, die Radiologen kannten die IVU-Diagnose nicht. Bei unklarer Diagnose wurden weitere Untersuchungen wie Computertomographie, retrograde Pyelographie oder Ureteroskopie durchgeführt. Die Diagnosen waren: Harnleitersteine bei 72 Patienten, Harnleitertumore bei 8 Patienten und extraureterale Tumore bei 2 Patienten. Eine richtige Diagnose bei den Steinpatienten wurde durch IVU bei 49 von 72 Patienten und durch MRU bei 64 von 72 Patienten gestellt. In dieser Patientengruppe wurden durch die MRU zwei falsche Diagnosen gestellt. Fehlende Kontrastmittelausscheidung war der Hauptgrund für Versagen der IVU. 3 der 8 Patienten mit Harnleitertumoren wurden durch die IVU richtig dignostiziert, bei dreien wurde eine falsche Diagnose gestellt. Durch die MRU konnten in dieser Gruppe 7 von 8 Patienten korrekt diagnostiziert werden, es wurde keine falsche Diagnose erhoben. IVU wird zunächst die Standarduntersuchungstechnik zur Darstellung des oberen Harntraktes bleiben, aber durch diese Studie konnte die Möglichkeit gezeigt werden, die in der MRU in Kombination mit Gadolinium und Furosemid liegt. Die größte Bedeutung dieser Untersuchung liegt in der urographisch stummen Niere, bei Untersuchungen in der Schwangerschaft, bei Kindern und bei Patienten mit Kontrastmittelunverträglichkeit.

    To determine the level of residual inflammation [synovitis, bone marrow edema (BME), tenosynovitis, and total inflammation] quantified by hand magnetic resonance imaging (h-MRI) in patients with rheumatoid arthritis (RA) in remission according to 3 different definitions of clinical remission, and to compare these remission definitions. A cross-sectional study. To assess the level of residual MRI inflammation in remission, cutoff levels associated to remission and median scores of MRI residual inflammatory lesions were calculated. Data from an MRI register of patients with RA who have various levels of disease activity were used. These were used for the analyses: synovitis, BME according to the Rheumatoid Arthritis Magnetic Resonance Imaging Scoring system, tenosynovitis, total inflammation, and disease activity composite measures recorded at the time of MRI. Receiver-operating characteristic analysis was used to identify the best cutoffs associated with remission for each inflammatory lesion on h-MRI. Median values of each inflammatory lesion for each definition of remission were also calculated. A total of 388 h-MRI sets of patients with RA with different levels of disease activity, 130 in remission, were included. Cutoff values associated with remission according to the Simplified Disease Activity Index (SDAI) ≤ 3.3 and the Boolean American College of Rheumatology/European League Against Rheumatism (ACR/EULAR) definitions for BME and tenosynovitis (1 and 3, respectively) were lower than BME and tenosynovitis (2 and 5, respectively) for the Disease Activity Score on 28 joints (DAS28) ≤ 2.6. Median scores for synovitis, BME, and total inflammation were also lower for the SDAI and Boolean ACR/EULAR remission criteria compared with DAS28. Patients with RA in remission according to the SDAI and Boolean ACR/EULAR definitions showed lower levels of MRI-detected residual inflammation compared with DAS28.

    To evaluate the association of synovitis, bone marrow edema (BME), and tenosynovitis in the progression of erosions quantified by hand magnetic resonance imaging (MRI) at 1 year in patients with early rheumatoid arthritis (RA) in remission. A total of 56 of 196 patients with early RA in remission at 1 year and with available MRI data at baseline and at 12 months were included. MRI images were assessed according to the Rheumatoid Arthritis Magnetic Resonance Imaging Scoring (RAMRIS) system. Persistent remission was defined as 28-joint Disease Activity Score-erythrocyte sedimentation rate ≤ 2.6 and/or Simplified Disease Activity Index ≤ 3.3 and/or the new boolean American College of Rheumatology/European League Against Rheumatism remission criteria for a continuous period of at least 6 months. Progression of bone erosions was defined as an increase of 1 or more units in annual RAMRIS score for erosions compared to baseline. At 1 year, the majority of patients with RA in sustained remission showed some inflammatory activity on MRI (94.6% synovitis, 46.4% BME, and 58.9% tenosynovitis) and 19 of the 56 patients (33.9%) showed MRI progression of bone erosions. A significant difference was observed in MRI BME at 1 year, with higher mean score in patients with progression compared to nonprogression of erosions (4.8 ± 5.6 and 1.4 ± 2.6, p = 0.03). Subclinical inflammation was identified by MRI in 96.4% of patients with RA in sustained clinical remission. Significantly higher scores of BME after sustained remission were observed in patients with progression of erosions compared to patients with no progression. The persistence of higher scores of BME may explain the progression of bone erosions in patients with persistent clinical remission.

    Full Text Available The association between rheumatoid arthritis (RA and calcium pyrophosphate dihydrate (CPPD crystal deposits can now be easily identified by MSUS, which is a noninvasive technique that can be applied to patients with painful joints and enthesis that are unexplained by rheumatoid activity. In this paper, we report an Egyptian case of a 51-year-old man who had rheumatoid arthritis since 7 years and developed bilateral knee and heel pain of 1.5 months’ duration with gradual onset and progressive course. Radiography revealed features of RA in both hands, as well as features of severe osteoarthritis in both knees with no signs of chondrocalcinosis. Ultrasonography of the joints, Achilles tendon, and plantar fascia detected knee, Achilles tendon, and plantar fascia calcifications, which are characteristic of CPPD, and supraspinatus calcification, which is characteristic of hydroxyapatite (HA deposition. Further investigations revealed no evidence of metabolic disorders. CPPD and HA crystals were identified in his synovial fluid. Subclinical affection with CPPD and HA crystals in RA can be easily detected by ultrasonography, which allows early management to prevent future attacks in RA patients that could lead to exacerbation of joint symptoms that may be missed as rheumatoid disease activity. Diet control and colchicine treatment may be more effective if started early before exacerbation.

    We present the ab initio study of spin-orbit coupling effects on laser cooling of BeI and MgI molecules. Potential energy curves for the X{sup 2}Σ{sup +}{sub 1/2}, A{sup 2}Π{sub 1/2,3/2}, and 2{sup 2}Π{sub 3/2,1/2} states are calculated using multi-reference configuration interaction method plus Davidson corrections. Spectroscopic parameters of BeI and MgI are in excellent agreement with available experimental and theoretical values. The A{sup 2}Π{sub 3/2} state of MgI is a repulsive state. It is an unsuitable scheme for the A{sup 2}Π{sub 3/2}(υ′)← X{sup 2}Σ{sup +}{sub 1/2} (υ″) transition for laser cooling of MgI. Highly diagonally distributed Franck-Condon factors f{sub 00} for the A{sup 2}Π{sub 1/2,3/2} (υ′ = 0) ← X{sup 2}Σ{sup +}{sub 1/2} (υ″ = 0) transitions and suitable radiative lifetimes τ for the A{sup 2}Π{sub 1/2,3/2} (υ′ = 0) of BeI and MgI are obtained. Three laser wavelength drives are required for the A{sup 2}Π{sub 1/2,3/2}(υ′)←X{sup 2}Σ{sup +}{sub 1/2} (υ″) transitions of BeI and MgI. The proposed cooling wavelengths of BeI and MgI are both in the violet region. The results imply the feasibility of laser cooling of BeI and MgI, and that laser cooling of BeI is more possible.

    Obwohl subklinische Enthesiopathie ein gut etabliertes diagnostisches Merkmal der Psoriasisarthritis (PsA) ist, wird sie häufig übersehen, da viele Patienten asymptomatisch sind. Gäbe es klinische Hinweise auf das Vorliegen einer Enthesiopathie, würde dies den Klinikern die Möglichkeit eröffnen, eine PsA frühzeitig zu diagnostizieren. Es wurde eine monozentrische prospektive Studie mit insgesamt 90 Psoriasis-Patienten durchgeführt, um mittels Ultraschall das Vorliegen von Enthesenanomalien zu untersuchen und eine Korrelation mit dem Befall der Nägel festzustellen. Enthesenanomalien wurden bei 23 Patienten (25,5 %) gefunden, von denen 19 (82,6 %) Nagelbefall aufwiesen. Bei 4 Patienten waren die Nägel nicht betroffen. Enthesiopathie lag bei 31,1 % (19/61) der Patienten mit Onychopathie vor, von den Patienten ohne Nagelbefall litten nur 13,8 % (4/29) an Enthesiopathie (p = 0,07). Zwischen dem Target-NAPSI-Score und dem Vorliegen einer Enthesiopathie bestand eine signifikante Korrelation. Eine signifikante Korrelation bestand darüber hinaus auch zwischen dem Vorliegen einer Enthesiopathie und der Anzahl der betroffenen Nägel (p = 0,035). Klinische Belege für eine Onychopathie können der Schlüssel für die frühe Diagnose einer Enthesiopathie bei Psoriasis-Patienten sein. © 2016 Deutsche Dermatologische Gesellschaft (DDG).

    The objective of this study was to determine whether radiographic damage is different in British black African patients with rheumatoid arthritis compared to Caucasian patients. Data on demographics, disease- and disability-related variables were obtained from all black African patients and their age-, gender- and disease-duration-matched Caucasian controls. After all features identifying the patients were concealed, X-rays of hands and feet were scored by using the Sharp/van der Heijde method. Data were analysed using Mann-Whitney U test, t test and chi (2) test. Sixty-four patients (32 in each ethnic group) were studied. The median age was 52 years and median disease duration 6 years. Seventy-two percent of patients were female. Black Africans and Caucasians did not differ significantly in rheumatoid factor positivity, disease-modifying anti-rheumatic drugs and biological treatment use. British black African patients had significantly more tender joints and disability. Joint space narrowing was significantly greater in Caucasian patients [48 (27-85) vs 56 (34-107), p = 0.01]. Caucasian patients had more number of erosions (172 vs 220) and higher erosion score; however, the difference in the erosion scores was not statistically significant [2 (0-48) vs 4.5 (0-46), p = 0.17]. Radiographic damage was less severe in black African patients with rheumatoid arthritis compared to their age-, gender- and disease-duration-matched Caucasian controls. A large prospective study is required to confirm the findings of this study and to establish the factors which might be accountable for any differences in the expression of rheumatoid arthritis in this ethnic group.

    The Strengthening and Stretching for Rheumatoid Arthritis of the Hand (SARAH) is a tailored, progressive exercise program for people having difficulties with wrist and hand function due to rheumatoid arthritis (RA). The program was evaluated in a large-scale clinical trial and was found to improve hand function, was safe to deliver, and was cost-effective. These findings led to the SARAH program being recommended in the UK National Institute for Health and Care Excellence guidelines for the management of adults with RA. To facilitate the uptake of this evidence-based program by clinicians, we proposed a Web-based training program for SARAH (iSARAH) to educate and train physiotherapists and occupational therapists on delivering the SARAH program in their practice. The overall iSARAH implementation project was guided by the 5 phases of the analysis, design, development, implementation, and evaluation (ADDIE) system design model. The objective of our study was to conduct the first 3 phases of the model in the development of the iSARAH project. Following publication of the trial, the SARAH program materials were made available to therapists to download from the trial website for use in clinical practice. A total of 35 therapists who downloaded these materials completed an online survey to provide feedback on practice trends in prescribing hand exercises for people with RA, perceived barriers and facilitators to using the SARAH program in clinical practice, and their preferences for the content and Web features of iSARAH. The development and design of iSARAH were further guided by a team of multidisciplinary health professionals (n=17) who took part in a half-day development meeting. We developed the preliminary version of iSARAH and tested it among therapists (n=10) to identify and rectify usability issues and to produce the final version. The major recommendations made by therapists and the multidisciplinary team were having a simple Web design and layout, clear

  5. An Improved BeiDou-2 Satellite-Induced Code Bias Estimation Method

    Full Text Available Different from GPS, GLONASS, GALILEO and BeiDou-3, it is confirmed that the code multipath bias (CMB, which originate from the satellite end and can be over 1 m, are commonly found in the code observations of BeiDou-2 (BDS IGSO and MEO satellites. In order to mitigate their adverse effects on absolute precise applications which use the code measurements, we propose in this paper an improved correction model to estimate the CMB. Different from the traditional model which considering the correction values are orbit-type dependent (estimating two sets of values for IGSO and MEO, respectively and modeling the CMB as a piecewise linear function with a elevation node separation of 10°, we estimate the corrections for each BDS IGSO + MEO satellite on one hand, and a denser elevation node separation of 5° is used to model the CMB variations on the other hand. Currently, the institutions such as IGS-MGEX operate over 120 stations which providing the daily BDS observations. These large amounts of data provide adequate support to refine the CMB estimation satellite by satellite in our improved model. One month BDS observations from MGEX are used for assessing the performance of the improved CMB model by means of precise point positioning (PPP. Experimental results show that for the satellites on the same orbit type, obvious differences can be found in the CMB at the same node and frequency. Results show that the new correction model can improve the wide-lane (WL ambiguity usage rate for WL fractional cycle bias estimation, shorten the WL and narrow-lane (NL time to first fix (TTFF in PPP ambiguity resolution (AR as well as improve the PPP positioning accuracy. With our improved correction model, the usage of WL ambiguity is increased from 94.1% to 96.0%, the WL and NL TTFF of PPP AR is shorten from 10.6 to 9.3 min, 67.9 to 63.3 min, respectively, compared with the traditional correction model. In addition, both the traditional and improved CMB model have

    Despite dramatic improvements in diagnostic imaging (ultrasonography, in particular endoscopic ultrasound, CT, MRI) treatment results of pancreatic cancer are still poor. Due to the lack of early symptoms, most tumors are diagnosed at an advanced stage of disease which excludes curative surgical treatment. FDG-PET has been shown to be effective in detecting pancreatic cancer as well as differentiating benign from malignant pancreatic tumors. Results might be further improved by applying quantitative analyses, in particular kinetic modelling of FDG metabolism. Nevertheless false negative as well as false positive findings may occur. Small lesions (lymphnode or liver metastases < 1 cm) might be missed, furthermore hyperglycemia often present in patients with pancreatic disease might reduce tumor uptake and subsequently tumor detectability by PET. False positive findings were reported in active pancreatitis and some benign tumors. Although PET proved to be superior to CT or ERCP in detecting cancer, clinical relevance of PET is limited due to the absence of therapeutic consequences to be derived from PET. As a consequence PET should only be used in patients with equivocal findings of morphological imaging (CT, ERCP) who are potential candidates for surgical treatment. (orig.) [German] Trotz verbesserter diagnostischer Moeglichkeiten (endoskopischer Ultraschall, Spiral-CT, MRT) sind die Behandlungsergebnisse bei Tumoren des exokrinen Pankreas nach wie vor unbefriedigend. Aufgrund der spaet einsetzenden klinischen Symptomatik wird die Diagnose meist erst bei lokaler Inoperabilitaet gestellt. Die FDG-PET has sich sowohl im Nachweis von Pankreaskarzinomen als auch bei der Differenzialdiagnose pankreatischer Raumforderungen bewaehrt und den etablierten bildgebenden Verfahren (Ultraschall, CT) als ueberlegen erwiesen. Weitere Verbesserungen erscheinen durch absolute Quantifizierung der FDG-Kinetik moeglich. Dennoch koennen falsch negative wie auch falsch positive Ergebnisse

    For optimal therapy management of patients with rheumatoid arthritis (RA) specific and sensitive diagnostic methods are essential for assessment of disease activity. In addition to projection radiography, imaging techniques, in particular magnetic resonance imaging (MRI) and ultrasound (US) are becoming increasingly more important for the early diagnosis of RA. The MRI and US techniques play a key role in the early imaging diagnostics of RA. Measurement of inflammation activity represents the basis of therapeutic decision-making and can be quantitatively and qualitatively determined with MRI and US. Synovitis and bone marrow edema are predictors of erosion. (orig.)

    A single photon absorption imaging technique has been developed to assess the bone mass of the hand, especially in patients with rheumatoid arthritis or bronchial asthma. A modified rectilinear scanner images the hand by transmission scanning in a water bath with a 7.4 GBq 125 I source. A microcomputer is used to calculate the bone mineral distribution, and the total bone mineral content (BMC) of the hand is determined from that distribution. The precision (coefficient of variation) of the measurement is 1.9%. A control population of 20 men and 58 women has been studied to determine normal variations in hand bone mineral content with age, sex, body size, hand volume and years since menopause. The normal men are found to have an average hand BMC of 25.1 g with a coefficient of variation (CV) of 22%, which is reduced to 12% by normalising for body size using span. The normal women had an average hand BMC of 18.0 g +- 15%. The CV is reduced to 13% by normalising for span and years post-menopause. (author)

    Cardiovascular magnetic resonance imaging (CMRI) has become the primary tool for the non-invasive assessment in patients with suspected myocarditis, especially after exclusion of acute coronary syndrome (ACS) for the differential diagnosis. Various MRI parameters are available which have different accuracies. Volumetric and functional ventricular assessment and the occurrence of pericardial effusion alone demonstrate only a poor sensitivity and specificity. The calculation of the T2-ratio (edema assessment), the early or global relative myocardial enhancement (gRE) and the late gadolinium enhancement (LGE), which represents irreversibly injured myocardium, are more specific parameters. All MRI parameters demonstrate the best accuracy in infarct-like acute myocarditis, whereas in chronic myocarditis sensitivity and specificity are less accurate. Therefore, a multisequential (at least two out of three parameters are positive) approach is recommended. The assessment of the value of newer, more quantitative MRI sequences, such as T1 and T2-mapping is still under investigation. (orig.) [German] Die kardiale MRT stellt die primaere nichtinvasive bildgebende Modalitaet bei Verdacht auf Myokarditis dar, insbesondere auch nach Ausschluss eines akuten Koronarsyndroms (ACS) zur Differenzialdiagnose. Verschiedene MR-Parameter mit unterschiedlicher Wertigkeit stehen zur Verfuegung. Die Beurteilung der Volumetrie und Ventrikelfunktion weisen ebenso wie der Nachweis eines Perikardergusses alleine nur eine geringe Sensitivitaet und Spezifitaet auf. Die spezifischeren MRT-Inflammationsparameter stellen die T2-Ratio (Oedemnachweis), die fruehe Kontrastmittelanreicherung bzw. das globale relative Enhancement (gRE) und die spaete Kontrastmittelanreicherung, das so genannte Late-Gadolinium-Enhancement (LGE) als Zeichen eines irreversiblen Myokardschadens dar.

    Radiotherapy is shown to be an effective, low-cost and non-invasive modality for treatment of induratio penis plastica. Its efficiency could be proven especially for inflammatory stages of the disease, or as an alternative after failure of conventional treatment. A total dose of no more than 20-25 Gy was found to achieve clear improvements in two thirds of the patients treated, while avoiding at the same time cosmetically disadvantageous late effects. (orig./CB) [Deutsch] Die Strahlentherapie ist eine wirksame, kostenguenstige und nicht-invasive Behandlungsmoeglichkeit bei Induratio penis plastica. Ihren Stellenwert konnte sie insbesondere im inflammatorischen Stadium und nach Versagen anderer konservativer Therapieansaetze zeigen.

    Full Text Available Introduction: Diseases of bones and joints have the third greatest impact on the health of the world population. Rheumatoid arthritis and osteoarthritis are uppermost inflammatory diseases of the joints. The aim of the study is the assessment of the ultrasonography and transillumination pulsooptometry of the knee joint as the diagnostic tools for rheumatoid arthritis and osteoarthrosis. Materials and Methods: 2 266 people (29 % – rheumatoid arthritis, 62 % – osteoarthritis, 9 % – healthy, aged 19–75 years took part in the study. The ultrasonography and transillumination pulsooptometry were conducted. Measurements of hemodynamics and optical density were performed using the device and method of Z. M. Sigal (2007. Results. Various indicators were established, for example, the volume of synovial fluid in the suprapatellar bag for rheumatoid arthritis and osteoarthritis. Optical density for rheumatoid arthritis is three times less than for osteoarthritis. There are significant differences in the amplitude of pulse oscillations in rheumatoid arthritis and osteoarthritis. Results: Various indicators were established, for example, the volume of synovial fluid in the suprapatellar bag for rheumatoid arthritis and osteoarthritis. Optical density for rheumatoid arthritis is three times less than for osteoarthritis. There are significant differences in the amplitude of pulse oscillations in rheumatoid arthritis and osteoarthritis. Discussion and Conclusions: The volume of synovial fluid in the suprapatellar bag of the knee joint with rheumatoid arthritis is higher than in osteoarthritis and normal: 55.8 cm3 and above and 3,29 cm3, 1,85 cm3 and below, respectively. With osteoarthritis and normal amount of synovial fluid did not differ significantly. The optical density in the suprapatellar bag of the knee joint for rheumatoid arthritis was 0.56 ± 0.2, the amplitude of pulse oscillations was 13.45 ± 3.62 mm.

    When chemical shift selective (CHESS) imaging is used with magnetic resonance imaging (MRI) for simultaneous imaging of both hands for the evaluation of rheumatoid arthritis, the fat suppression effect is poor. We investigated whether these fat-suppressed images using CHESS could be improved with the use of rice pads. T1-weighted images were obtained with CHESS and the same imaging parameters were used with and without rice pads on the coronal plane of both hands in 10 healthy volunteers. Patients were placed in a prone position with both hands extended overhead. The fat-suppression effect was classified into four categories and scored for both sets of images, and visual assessments were made by one radiologist and one radiologic technologist. The evaluation score was 1.1 for the images made without rice pads, and 3.2 for the images made with rice pads. The fat suppression effect was thus significantly better in the images made using rice pads (P < 0.0001). Lingering fat signals disappeared almost completely in images of both hands using CHESS with rice pads, and it was confirmed that the images were improved and had good fat suppression. More accurate evaluation of inflammatory sites that occur in rheumatoid arthritis may thus be possible, promising better diagnostic accuracy.

    The aim of this study was to evaluate the performance of digital radiography in the detection of early very small erosions and joint space narrowing in the hands and feet in rheumatoid arthritis. Fifty-three sets of film-screen and digital radiographs of the same hands and feet with very small and sometimes questionable lesions (possible erosions and cysts) were scored independently two times by four investigators. The percentage of lesions found in exactly the same position for each investigator was calculated. Intra-observer agreement between first and second reading in film-screen radiography was 64-76 % (mean 67 %), and in digital radiographs 60-71 % (mean 64 %). Agreement between film-screen and digital radiographs ranged from 54 to 64 % (mean 58 %) in the first reading and from 56 to 66 % (mean 62 %) in the second reading. Overall agreement between both techniques between first and second reading ranged between 62 and 73 % (mean 65 %). Digital radiography of the hands and feet can be used in patients suspected of rheumatoid arthritis and in follow-up of those patients, because small and early erosions can be seen equally well with the digital technique as compared with the conventional film-screen technique.

    Full Text Available Rheumatoid arthritis (RA is a chronic inflammatory autoimmune disorder culminating in joint destruction with functional impairment & deformities. This disease is associated with poor nutritional status in relation to various nutrients due to not only because of increased requirements & reduction in their absorption but also due to disease modifying anti-rheumatoid drugs (DMARD’s, Non-steroidal Anti-inflammatory Drugs (NSAID’s & corticosteroids prescribed to alleviate symptoms of this disease. This results in associated side effects like gastrointestinal bleeding & bone loss (osteoporosis. Supplementation with long chain n-3 polyunsaturated fatty acids (PUFA has constantly demonstrated an improvement in symptoms & reduction in dosages of NSAID’s. Such a supplementation can be provided with the use of fish oils which have an anti-inflammatory potential. Vitamin C (ascorbic acid use has been found to augment the anti-oxidant defenses, so also the use of Vitamin E (tocopherol which has got antiinflammatory action. Beneficial effects of Vitamin B6 (pyridoxal 5-phosphate used in conjunction with folate & Vitamin B12 have been documented in those group of RA patients with high homocysteine metabolism, there by reducing the cardiovascular risk in these patients. In addition role of Selenium, Iron, Zinc, Calcium, and Vitamin D has been discussed in this review article. Besides adding certain nutrients in food, elimination of certain foods like red meat, dairy products, cereals & wheat gluten have shown improvement in progression of this disease. This article emphasizes the need for dietary supervision in the hands of expert dietician, of the Rheumatoid arthritis patients.

    Shoulder arthrography in a patient with rheumatoid arthritis is performed to differentiate between a rheumatoid flare and limitation of motion secondary to tear in the rotator cuff. Accurate diagnosis is important because of the therapeutic implications. The arthrographic findings characteristic of rheumatoid involvement of the shoulder joint are nodular filling defects of the joint, the subacromial and subdeltoideal bursa in case of rotator cuff tear, irregular capsular attachment, contracted joint space and visualized lymphatic drainage. A dilatation of the biceps tendon sheath has not been shown. (orig.) [de

  12. Die Rolle von RANK-Ligand und Osteoprotegerin bei Osteoporose

    Directory of Open Access Journals (Sweden)

    Hofbauer LC

    2004-01-01

    Full Text Available Receptor activator of nuclear factor (NF- κB ligand (RANKL, sein zellulärer Rezeptor RANK und der Decoy-Rezeptor Osteoprotegerin (OPG stellen ein essentielles Zytokinsystem für die Zellbiologie von Osteoklasten dar. Verschiedene Untersuchungen belegen die Bedeutung von Störungen des OPG/RANKL/RANK-Systems bei der Pathogenese metabolischer Knochenerkrankungen. In dieser Arbeit werden die wichtigsten Störungen des OPG/RANKL/RANK-Systems bei verschiedenen Osteoporoseformen dargestellt. Östrogenrezeptor- (ER- Agonisten wie 17 β-Östradiol, Raloxifen und Genistein stimulieren die osteoblastäre Produktion von OPG durch Aktivierung von ER- α in vitro, während Lymphozyten von Patientinnen mit Östrogenmangel RANKL überexprimieren. Die parenterale Gabe von OPG vermag den mit Östrogenmangel assoziierten Knochenverlust im Tiermodell und in einer kleineren klinischen Studie zu verhindern. Glukokortikoide und Immunsuppressiva steigern gleichzeitig die RANKL-Expression und hemmen die OPG-Produktion in osteoblastären Zellen in vitro. Glukokortikoide sind auch in vivo imstande, die OPG-Serumspiegel deutlich zu reduzieren. Dagegen hemmen biomechanische Reize in vitro die RANKL-Produktion und steigern die OPG-Produktion. Ein Fehlen dieser biomechanischen Reize bei längerer Immobilisierung kann daher den RANKL/OPG-Quotienten steigern, während die tierexperimentelle Immobilisierungs-Osteoporose durch die parenterale Gabe von OPG gemildert werden kann.

    2014-04-01

    Full Text Available State of the art Precise Point Positioning (PPP is currently based on dual-frequency processing of GPS and Glonass navigation systems. The International GNSS Service (IGS is routinely providing the most accurate orbit and clock products for these constellations, allowing point positioning at centimeter-level accuracy. At the same time, the GNSS landscape is evolving rapidly, with the deployment of new constellations, such as Galileo and BeiDou. The BeiDou constellation currently consists of 14 operational satellites, and the 4 Galileo In-Orbit Validation (IOV satellites are transmitting initial Galileo signals. This paper focuses on the integration of Galileo and BeiDou in PPP, together with GPS and Glonass. Satellite orbits and clocks for all constellations are generated using a network adjustment with observation data collected by the IGS Multi-GNSS Experiment (MGEX, as well as from Fugro proprietary reference station network. The orbit processing strategy is described, and orbit accuracy for Galileo and BeiDou is assessed via orbit overlaps, for different arc lengths. Kinematic post-processed multi-GNSS positioning results are presented. The benefits of multiconstellation PPP are discussed in terms of enhanced availability and positioning accuracy.

    Arthritis of the hand can limit a person's ability to perform daily activities. Whether or not sensory deficits contribute to the disability in this population remains unknown. The primary purpose of this study was to determine if women with osteoarthritis (OA) or rheumatoid arthritis (RA) of the hand have sensory impairments. Sensory function in the dominant hand of women with hand OA or RA and healthy women was evaluated by measuring sensory nerve action potentials (SNAPs) from the median, ulnar and radial nerves, sensory mapping (SM), and vibratory and current perception thresholds (VPT and CPT, respectively) of the second and fifth digits. All SNAP amplitudes were significantly lower for the hand OA and hand RA groups compared with the healthy group (p sensory fibers in the median, ulnar and radial nerves. Less apparent were losses in conduction speed or sensory perception.

    Full Text Available Involvement of the cervical spine is common in rheumatoid arthritis. Clinical presentation can be variable, and symptoms may be due to neck pain or compressive myeloradiculopathy. We discuss the pathology, grading systems, clinical presentation, indications for surgery and surgical management of cervical myelopathy related to rheumatoid arthritis in this paper. We describe our surgical technique and results. We recommend early consultation for surgical management when involvement of the cervical spine is suspected in rheumatoid arthritis. Even patients with advanced cervical myelopathy should be discussed for surgical treatment, since in our experience improvement in function after surgery is common.

    This paper gives an overview of experience and success of percutaneous transhepatic interventions in malignant biliary obstruction. Even after exhaustion of surgical and endoscopic therapy options, the percutaneously inserted stents provide effective palliation. The palliative treatment of malignant jaundice using a stent is an established procedure in clinical practice, particularly whenever the endoscopic, transpapillary approach is not possible due to high obstructions or previous surgery. The technical success rate is very high (about 95-100%), and the complication rate is about 10-30%. Since the patency rate of stents is higher than that of plastic endoprostheses, their primary use is justified despite higher costs, provided the patients are adequately selected. (orig.) [German] Vorgelegt wird eine Uebersicht ueber den gegenwaertigen Stellenwert radiologischer Interventionen bei malignen Gallenwegstenosen, die nur bei 10-20% der Patienten heilbar sind. Wenn ein endoskopisch transpapillaerer Zugang nicht moeglich ist, z. B. bei hohen Obstruktionen oder nach frueheren Eingriffen, ermoeglichen die perkutane transhepatische Punktion und Implantation von Metallendoprothesen eine gute Palliation. Die perkutane Gallengangdrainage und Stentplatzierung sind fuer den erfahrenen, interventionell taetigen Radiologen wenig kompliziert und mit einer Erfolgsrate von 95-100% dem endoskopischen Vorgehen deutlich ueberlegen. Morbiditaet und Mortalitaet der endoskopischen Verfahren waren in aelteren Arbeiten noch geringer als die der perkutanen Methoden. Aktuellen Studien zufolge sind beide Verfahren gleichwertig, wahrscheinlich aufgrund technischer Verbesserungen der perkutanen Interventionen. Die technische Erfolgsrate bei der Stentapplikation liegt ueber 95%. Mittels perkutaner transhepatischer biliaerer Drainageneinlage (PTCD) eingelegte Metallstents bleiben haeufiger und laenger offen als Plastikstents.

    Full Text Available Einleitung:Die Sextantenbiopsie der Prostata ist für eine verlässliche Karzinomdiagnostik nicht ausreichend. Vielerorts werden bereits bei der Erstbiopsie 12 Stanzen entnommen. In einer großen Serie von 10-fach-Biopsien unter bilateraler lokaler Leitungsanästhesie, wie bereits 2002 publiziert [1], überprüften wir die Qualität unserer Technik als Standard für die Erstbiopsie. Methode:Zwischen April 2005 und Dezember 2007 führten wir bei 736 Männern (Durchschnittsalter 67,5 ± 8,39 Jahre die Erstbiopsie der Prostata durch. Indikation für die Biopsie war entweder ein erhöhter PSA-Wert oder ein auffälliger Tastbefund. Bei allen Männern erfolgte die Biopsie der Prostata unter bilateraler lokaler Leitungsanästhesie. Es wurden nur Proben aus der peripheren Zone der Prostata unter transrektaler Ultraschallkontrolle entnommen. Ergebnisse:Durch die Biopsie wurde in 372 von 736 Fällen (50,5 % ein Karzinom identifiziert. Die Karzinomdetektionsrate war proportional zum PSA-Wert und indirekt proportional zum Organvolumen. Es zeigte sich eine eindeutige Korrelation zwischen der Anzahl positiver Stanzen bei der Biopsie mit dem pathologischen Stadium des Prostatektomiepräparates. 12 Männer (1,6 % mussten wegen akuter Prostatitis und 5 (0,7 % wegen rektaler Blutung wieder ins Krankenhaus eingewiesen werden. Von den 182 Patienten des Untersuchers R. v. K. wurde der durchschnittliche Schmerz der Biopsie mit 1,69 von maximal 10 angegeben. Die Detektions- und Komplikationsraten dieser Biopsietechnik unterschieden sich nicht nach Durchführung von Assistenz- oder Fachärzten. Schlussfolgerung: Die präsentierte Biopsietechnik liefert mit nur 10 Stanzen eine überlegene Detektionsrate und eine geringe Rate an Komplikationen. Sie sollte als Basis für die Definition eines Standards für die Erstbiopsie der Prostata bei Karzinomverdacht dienen.

    Rheumatoid arthritis preferrably becomes manifest at the synovial joints of the limbs, especially at the small joints of the hands and feet, at bursae and synovial sheathes. The pathologic lesions are less frequently found at cartilaginous joints or entheses. The lesions very often are symmetrically distributed and are characterized by the following: 1. A periarticular, spindle-shaped opacity with a density similar to soft-tissue, induced by an inflammatory hypertrophy of the synovia, a serosynovitis, or an edematous impregnation of the periarticular tissue. 2. A juxta-articular osteoporosis, most probably caused by a neighbouring synovialitis accompanied by hyperemia. 3. A diffuse joint cavity narrowing due to a destruction of the articular cartilage by the pannus, a fibrovascular resorptive tissue. 4. Central as well as marginal erosions, caused by destruction of ossous material by the pannus. 5. Subchondral signal cysts, likewise unduced by the pannus. (Orig./AJ) [de

    Full Text Available Bedingt durch Fortschritte in der Behandlung von Tumoren hat sich die Lebenserwartung von Krebspatienten deutlich verbessert. Jedoch steigt hiermit auch die Inzidenz von Knochenmetastasen. Mit wenigen Ausnahmen, die primären Knochentumoren betreffend, ist die Art der Behandlung dieser Läsionen in der Regel palliativ. Durch operatives Intervenieren muß bei diesen Patienten ein maximaler palliativer Effekt bei minimaler Morbidität und Mortalität erzielt werden. Die vorwiegenden Ziele sind Schmerzreduktion unter Erhalt der Stabilität und Funktion. Durch die Kyphoplastie wurden Zementierungsverfahren an der Wirbelsäule auch für pathologische Frakturen auf dem Boden metastatischer Manifestationen elegibel. In einer telefonischen Evaluation von 10 Patienten konnte die Wertigkeit des Verfahrens in der palliativen Situation bei Patienten mit Wirbelsäulenmetastasen gezeigt werden.

Patients with ''overlap'' syndromes (i.e., mixed connective tissue disease, systemic lupus erythematosus or rheumatoid arthritis) have been excluded. Soft tissue changes included atrophy (hidebound skin), and dystrophic calcifications, particularly in CREST patients (calcinosis, Raynaud phenomenon, esophageal dysmobility, sclerodactily and telangectasia). The most common bony change is resorption of distal phalanges; diffuse osteoporosis is also frequent; the distal interphalangeal and first carpometacarpal joints involvement appear as a distinctive feature of this e....

In recent years, more and more data indicate an existing relationship between periodontal disease and rheumatoid arthritis. The link between both diseases has been confirmed in multiple studies. Despite the fact that this association might be based on shared environmental and genetic risk factors, a possible causal relation was advocated by experimental, epidemiological and interventional studies, with the leading role of Porphyromonas gingivalis. Individuals with chronic periodontitis are at an increased risk of developing rheumatoid arthritis, as well as rheumatoid arthritis patients are at an increased risk of chronic periodontitis and more severe forms of periodontitis. Furthermore, there is a correlation between the activity in both diseases – patients with more severe periodontitis suffer from more active rheumatoid arthritis. Intervention attempts were also performed, which demonstrated that eliminating periodontal infection and inflammation can affect the severity of rheumatoid arthritis. In this paper, we review the current knowledge about the link between both diseases, focusing on its clinical implications. Will periodontal treatment become a part of standard therapy for rheumatoid arthritis?

    Full Text Available The article deals with the issue of psychic problems of rheumatoid arthritis patients. Rheumatoid arthritis is a chronic, inflammatory motor system disease with comprehensive impact on the patient's life. The disease is often considered an exclusively physical disease. But such approach is insufficient because the disease is accompanied by motor limitations of different intensities, by pain and by fatigue that cause considerable exhaustion to the patient. The patients often must give up their hobbies and in some cases even their jobs. In most serious cases, even common daily activities including self–servicing actions become an obstacle to the patient. It is therefore logical that the psyche of a patient with such disease is considerably strained. One of the partial goals of the study consisted in mapping the subjectively perceived quality of life of rheumatoid arthritis patients in facet 8, "negative feelings", and in ascertaining whether there is statistically significant relation to facets 1, "pain and discomfort", and 2, "energy and fatigue". Another goal consisted in comparing the subjectively perceived quality of life between men and women with rheumatoid arthritis, as well as between population of rheumatoid arthritis patients and control healthy population. The study was implemented within the research project of the Grant Agency of the University of South Bohemia in České Budějovice number 120/2012/S, „Reflection of quality of life in nursing", under use of two standardized questionnaires, WHOQOL–100 and HAQ. This article presents exclusively the data acquired based on the WHOQOL–100 questionnaire. The research set consisted of patients suffering from rheumatoid arthritis from all over the Czech Republic.

    The performance of real-time (RT) precise positioning can be improved by utilizing observations from multiple Global Navigation Satellite Systems (GNSS) instead of one particular system. Since the end of 2012, BeiDou, independently established by China, began to provide operational services for users in the Asia-Pacific regions. In this study, a regional RT precise positioning system is developed to evaluate the performance of GPS/BeiDou observations in Australia in providing high precision positioning services for users. Fixing three hourly updated satellite orbits, RT correction messages are generated and broadcasted by processing RT observation/navigation data streams from the national network of GNSS Continuously Operating Reference Stations in Australia (AUSCORS) at the server side. At the user side, RT PPP is realized by processing RT data streams and the RT correction messages received. RT clock offsets, for which the accuracy reached 0.07 and 0.28 ns for GPS and BeiDou, respectively, can be determined. Based on these corrections, an accuracy of 12.2, 30.0 and 45.6 cm in the North, East and Up directions was achieved for the BeiDou-only solution after 30 min while the GPS-only solution reached 5.1, 15.3 and 15.5 cm for the same components at the same time. A further improvement of 43.7, 36.9 and 45.0 percent in the three directions, respectively, was achieved for the combined GPS/BeiDou solution. After the initialization process, the North, East and Up positioning accuracies were 5.2, 8.1 and 17.8 cm, respectively, for the BeiDou-only solution, while 1.5, 3.0, and 4.7 cm for the GPS-only solution. However, we only noticed a 20.9% improvement in the East direction was obtained for the GPS/BeiDou solution, while no improvements in the other directions were detected. It is expected that such improvements may become bigger with the increasing accuracy of the BeiDou-only solution.

    Overhead sport places great demands on the shoulder joint. Shoulder pain in overhead athletes and throwers can in the majority of cases be attributed to lesions resulting from chronic overuse of tendons and capsuloligamentous structures or to sequels of microinstability and secondary impingement. Due to its great impact on therapeutic decisions, imaging in athletes with unclear shoulder pain is a challenge. In this connection, magnetic resonance (MR) arthrography represents the cross-sectional imaging modality of first choice, as it allows depiction and exclusion of pathologic alterations of all relevant joint structures with sufficient confidence. This article reviews the biomechanical and clinical aspects and MR arthrographic features of the most common shoulder pathologies in overhead athletes, including biceps tendinopathy, superior labral anterior-posterior (SLAP) lesions, rotator cuff lesions, as well as extrinsic and intrinsic impingement syndromes. (orig.) [German] Ueberkopfsportarten stellen grosse Anforderungen an das Schultergelenk. Schulterbeschwerden bei Ueberkopf- und Wurfsportlern koennen in der Mehrzahl der Faelle auf eine chronische Ueberlastung von Sehnen und Kapsel-Band-Strukturen oder auf die Folgen einer Mikroinstabilitaet und sekundaerer Impingementsyndrome zurueckgefuehrt werden. Wegen ihres grossen Einflusses auf die Therapieentscheidung stellt die Bildgebung bei Athleten mit unklaren Schulterbeschwerden eine Herausforderung dar. Die MR-Arthrographie ist in diesem Zusammenhang als Schnittbildverfahren der ersten Wahl anzusehen, da sie den Nachweis bzw. Ausschluss pathologischer Veraenderungen aller relevanten Gelenkstrukturen mit ausreichender Sicherheit ermoeglicht. Dieser Artikel gibt eine Uebersicht ueber biomechanische und klinische Aspekte sowie MR-arthrographische Befunde der haeufigsten Schultergelenkpathologien bei Ueberkopfsportlern, wie Bizepstendinopathie, Superior-labral-anterior-posterior- (SLAP-)Laesionen, Laesionen der

    Functional magnetic resonance imaging uses the blood oxygen level-dependent effect (BOLD MRI) for noninvasive display of cerebral correlatives of cognitive function. The importance for the understanding of physiological and pathological processes is demonstrated by investigations of working memory in schizophrenics and healthy controls. Working memory is involved in processing rather than storage of information and therefore is linked to complex processes such as learning and problem solving. In schizophrenic psychosis, these functions are clearly restricted. Training effects in the working memory task follow an inverse U-shape function, suggesting that cerebral activation reaches a peak before economics of the brain find a more efficient method and activation decreases. (orig.) [German] Die funktionelle Magnetresonanztomographie (fMRT) nutzt den ''blood oxygen level dependent effect'' (BOLD-Effekt) zur nichtinvasiven Darstellung zerebraler Korrelate kognitiver Funktionen. Die Bedeutung dieses Verfahrens fuer das Verstaendnis physiologischer und pathologischer Prozesse wird anhand von Untersuchungen zum Arbeitsgedaechtnis bei Schizophrenen und gesunden Kontrollpersonen verdeutlicht. Das Arbeitsgedaechtnis dient weniger der Speicherung, sondern vielmehr der Verarbeitung von Informationen und ist deshalb in komplexe Prozesse wie Lernen und Problemloesen eingebunden. Im Rahmen schizophrener Psychosen kommt es zu einer deutlichen Einschraenkung dieser Funktionen. Erwartungsgemaess zeigen sich unter Durchfuehrung eines Arbeitsgedaechtnisparadigmas Unterschiede in der zerebralen Aktivitaet, die jedoch bei den Erkrankten unter Therapie prinzipiell reversibel sind. Von Interesse sind auch Trainingseffekte bei Gesunden, wobei eine verminderte Aktivierung nach Training auf eine ''Oekonomisierung'' schliessen laesst. (orig.)

    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.

    Rheumatoid arthritis is thought to induce conductive hearing loss and/or sensorineural hearing loss. This study evaluated the function of the middle ear and cochlea, and the related factors. Pure tone audiometry, speech reception thresholds, speech discrimination scores, tympanometry, acoustic reflexes, and distortion product otoacoustic emissions were assessed in rheumatoid arthritis patients and healthy volunteers. Pure tone audiometry results revealed a higher bone conduction threshold in the rheumatoid arthritis group, but there was no significant difference when evaluated according to the sensorineural hearing loss definition. Distortion product otoacoustic emissions related prevalence of conductive or mixed hearing loss, tympanometry values, acoustic reflexes, and speech discrimination scores were not significantly different between the two groups. Sensorineural hearing loss was significantly more prevalent in patients who used azathioprine, cyclosporine and etanercept. Higher bone conduction thresholds in some frequencies were detected in rheumatoid arthritis patients that were not clinically significant. Sensorineural hearing loss is significantly more prevalent in refractory rheumatoid arthritis patients.

    Background Rheumatoid factor causes positive interference in multiple immunoassays. Recently, negative interference has also been found in immunoassays in the presence of rheumatoid factor. The chemiluminescent microparticle immunoassay is widely used to determine serum alpha-fetoprotein. However, it is not clear whether the presence of rheumatoid factor in the serum causes interference in the chemiluminescent microparticle immunoassay of alpha-fetoprotein. Methods Serum alpha-fetoprotein was determined using the ARCHITECT alpha-fetoprotein assay. The estimation of alpha-fetoprotein recovery was carried out in samples prepared by diluting high-concentration alpha-fetoprotein serum with rheumatoid factor-positive or rheumatoid factor-negative serum. Paramagnetic microparticles coated with hepatitis B surface antigen-anti-HBs complexes were used to remove rheumatoid factor from the serum. Results The average recovery of alpha-fetoprotein was 88.4% and 93.8% in the rheumatoid factor-positive and rheumatoid factor-negative serum samples, respectively. The recovery of alpha-fetoprotein was significantly lower in the rheumatoid factor-positive serum samples than in the rheumatoid factor-negative serum samples. In two of five rheumatoid factor-positive samples, a large difference was found (9.8%) between the average alpha-fetoprotein recoveries in the serially diluted and initial recoveries. Fourteen rheumatoid factor-positive serum samples were pretreated with hepatitis B surface antigen-anti-HBs complex-coated paramagnetic microparticles. The alpha-fetoprotein concentrations measured in the pretreated samples increased significantly. Conclusions It was concluded that the alpha-fetoprotein chemiluminescent microparticle immunoassay is susceptible to interference by rheumatoid factor, leading to significantly lower results. Eliminating the incidence of negative interference from rheumatoid factor should be an important goal for immunoassay providers. In the meantime

    Informationen zur Häufigkeit von Arzneimittelwechselwirkungen und unerwünschten Arzneimittelwirkungen zu präsentieren und Hilfestellung zu leisten, wie diese wichtigen Probleme in der pharmakologischen Behandlung stationärer dermatologischer Patienten minimiert werden können. Die Medikation von 1 099 stationären dermatologischen Patienten wurde retrospektiv mittels einer Internet-basierten Software für Medikamenteninteraktionen (Diagnosia ® Check) auf Arzneimittelwechselwirkungen und unerwünschte Arzneimittelwirkungen analysiert. Wir beschreiben eine Gesamthäufigkeit relevanter Arzneimittelwechselwirkungen von 51,7 % mit durchschnittlich 3,2 Interaktionen pro betroffenem stationären Patienten. Arzneimittelkombinationen, die gemieden werden sollten, wurden bei 5,7 % der Studienpopulation festgestellt. Der wichtigste Risikofaktor war die Gesamtzahl der verabreichten Medikamente. Die Arzneimittelgruppen, die bei der Mehrzahl der Wechselwirkungen beteiligt waren, waren Analgetika, Herz-Kreislauf-Medikamente und gerinnungshemmende Medikamente sowie Antidepressiva. Das Risiko unerwünschte Arzneimittelwirkungen auszubilden wurde bei 53,1 % der stationären Patienten als "hoch" eingestuft. Die fünf wichtigsten unerwünschten Nebenwirkungen in dieser Patientengruppe waren Blutungen, Obstipation, anticholinerge Effekte, Sedierung und orthostatische Effekte. Potenzielle Arzneimittelwechselwirkungen sowie unerwünschte Arzneimittelwirkungen sind bei stationären dermatologischen Patienten alarmierend häufig. Bei jedem zweiten Patienten besteht die Gefahr, derartige Wechselwirkungen oder unerwünschte Nebenwirkungen zu erleiden und jeder zwanzigste Patient erhält eine Arzneimittelkombination, die nicht verabreicht werden sollte. Erhöhte Wachsamkeit ist erforderlich, um die gefährdeten Patienten zu erkennen. © 2016 Deutsche Dermatologische Gesellschaft (DDG). Published by John Wiley & Sons Ltd.

    Purpose: Extracranial metastases of malignant gliomas are rare. We report 2 cases with spinal metastases in patients suffering from glioma. Patients and Method: Two patients (33 and 57 years old) developed spinal canal metastases of a glioblastoma multiforme and anaplastic astrocytoma Grade III respectively 25 and 9 months after surgical resection and radiotherapy. Both metastases were confirmed pathohistologically. Results: Intraspinal metastases were irradiated with a total dose of 12.6 Gy and 50 Gy. Treatment withdrawal was necessary in one patient due to reduced clinical condition. Regression of neurological symptoms was observed in the second patient. Conclusions: Spinal spread of malignant glioma should be considered during care and follow-up in glioma patients with spinal symptoms. (orig.) [Deutsch] Hintergrund: Maligne Gliome metastasieren aeusserst selten extrakraniell. Wir stellen zwei Faelle einer spinalen Filialisierung bei Gliompatienten vor. Patientengut und Methode: Zwei Patienten (33 und 57 Jahre alt) entwickelten 25 bzw. neun Monate nach Resektion und postoperativer Radiatio eines Glioblastoma multiforme und eines anaplastischen Astrozytoms WHO-Grad III histologisch gesicherte intraspinale Metastasen, welche durch Sensibilitaetsstoerungen der Beine symptomatisch wurden. Ergebnisse: Die intraspinalen Filiae wurden mit 12,6 Gy bzw. 50 Gy bestrahlt. Bei einem Patienten musste die Radiatio wegen zunehmender Verschlechterung des Allgemeinzustandes abgebrochen werden, bei dem zweiten Patienten besserte sich die neurologische Symptomatik. Schlussfolgerung: Bei der Betreuung von Gliompatienten sollte, insbesondere in der Nachsorge, an die Moeglichkeit der spinalen Metastasierung mit entsprechender Symptomatik gedacht werden. (orig.)

    When chemical shift selective (CHESS) imaging is used with magnetic resonance imaging (MRI) for simultaneous imaging of both hands for the evaluation of rheumatoid arthritis, the fat suppression effect is poor. We investigated whether these fat-suppressed images using CHESS could be improved with the use of rice pads. T1-weighted images were obtained with CHESS and the same imaging parameters were used with and without rice pads on the coronal plane of both hands in 10 healthy volunteers. Patients were placed in a prone position with both hands extended overhead. The fat-suppression effect was classified into four categories and scored for both sets of images, and visual assessments were made by one radiologist and one radiologic technologist. The evaluation score was 1.1 for the images made without rice pads, and 3.2 for the images made with rice pads. The fat suppression effect was thus significantly better in the images made using rice pads (PCHESS with rice pads, and it was confirmed that the images were improved and had good fat suppression. More accurate evaluation of inflammatory sites that occur in rheumatoid arthritis may thus be possible, promising better diagnostic accuracy. Copyright © 2011 Elsevier Ireland Ltd.

    Bei der Dosimetrie von Photonenstrahlungen mit luftgefüllten Ionisationskammern werden in diesem Kapitel zwei Grenzfälle unterschieden. Der eine Fall ist die Bedingung des so genannten Sekundärelektronengleichwichts im Kammervolumen. In diesem Fall bestimmen ausschließlich die Photonen im Messvolumen die dosimetrische Anzeige. Der zweite Grenzfall ist gegeben, wenn das Luftvolumen und die Kammer das Strahlungsfeld im Phantom so wenig stören, dass der Sekundärelektronenfluss unverändert bleibt. Diese Bedingungen nennt man BRAGG-GRAY-Bedingungen. Beide Grenzfälle sind in der Praxis nur näherungsweise zu verwirklichen. Abweichungen müssen durch entsprechende Korrekturen oder Kalibrierungen berücksichtigt werden.

    Full Text Available Seit einigen Jahren ist die Analyse von EEG-Signalen bei Epilepsie Gegenstand zahlreicher wissenschaftlicher Arbeiten; Zielvorstellung ist dabei die Entwicklung von Verfahren zur Erkennung eines möglichen Voranfallszustandes. Im Vordergrund steht beispielsweise die Approximation einer so genannten effektiven Korrelationsdimension, die Bestimmung der maximalen Lyapunov-Exponenten, Detektionsverfahren für Muster bei Zellularen Nichtlinearen Netzwerken, die Bestimmung der mittleren Phasenkohärenz und Verfahren zur nichtlinearen Prädiktion von EEG-Signalen. Trotz umfangreicher Bemühungen kann bis heute eine Erkennung von Anfallsvorboten mit einer Sensitivität und Spezifität, die eine automatisierte Anfallsvorhersage ermöglichen würde, noch nicht durchgeführt werden. In diesem Beitrag werden neue Ergebnisse zur Prädiktion von EEG-Signalen bei Epilepsie vorgestellt. Dabei werden Signale, welche mittels intrakranieller electrocorticographischer (ECoG und stereoelectroencephalographischer (SEEG Ableitungen registriert wurden, segmentweise analysiert. Unter der Annahme, dass sich Änderungen des Systems ,,Gehirn" als Änderungen im Prädiktor, d.h. in seinen Systemparametern widerspiegeln, könnte eine nähere Betrachtung der Prädiktoreigenschaften zu einer Erkennung von Anfallsvorboten führen.

    National University of Water and Environmental Engineering   Abstract Background: Rheumatoid arthritis is one of the most common forms of inflammatory diseases of the joints. The disease leads to deformation, then to destruction of the diseased joint and to disability. Physiotherapy is used for the treatment and rehabilitation of rheumatoid arthritis. It is assumed that physiotherapy treatments that promote remission of the disease, improve the quality of patients’ life, create the necessary conditions for comprehensive rehabilitation programs. Objective: Systematic’s review conducting of studies that assess the effect of physiotherapy in the rehabilitation of patients with rheumatoid arthritis. Methods: Theoretical analysis of scientific and methodical literature, methods of analysis, synthesis, generalization. Results: To reduce inflammation in the joints is performed UV of affected joints weak or medium erythermal or middle erythermal doses used UHF therapy. UHF-therapy prescribed to the area of joint in I or II dose, duration 10 min., the course – 5-8 treatments. For patients with minimal activity is added electrophoresis NSAIDs. Electrophoresis aspirin is applied on the affected joints (every day, the course – 10-12 procedures, which favorably affect the course of rheumatoid arthritis. Conclusions: Physical therapy can reduce pain and stiffness in the joints, prevent deformity and restore function, improve independence and quality of life. State of the art is a major incentive to develop new activities in the treatment and rehabilitation of patients with rheumatoid arthritis to improve joint functional activity and their physical health.   Keywords: rheumatoid arthritis, physiotherapy, rehabilitation, hydrotherapy.

    Eclampsia is a rare but severe complication during the course of a pregnancy. The CT-findings at the brain are well known. Reports on MRT-findings are limited, however, especially in German literature. We describe the MRT picture of the cerebral changes caused by eclampsia and discuss the advantages of MRT in comparison with CT. The use of contrast agents with MRT shows breakdown of blood-brain barrier but does not provide any information of therapeutical consequences and should be avoided during pregnancy. An early and targeted use of MRT in any case of unclear or suspicious neurological symptoms during pregnancy is recommended. MRT supports differential diagnosis regarding non pregnancy-related cerebral disease and can be helpful for therapy planning in cases of preeclampsia. Additionally, MRT offers the possibility to control the effect of therapy with regard to brain damage. (orig.) [Deutsch] Die Eklampsie ist eine seltene aber erhebliche Komplikation im Verlauf einer Schwangerschaft. Die computertomographischen Veraenderungen im Gehirn sind bekannt. Mitteilungen von kernspintomographischen Befunden finden sich vor allem in der deutschen Literatur noch selten.

Die Gabe von Kontrastmittel bei der MRT weist zwar die Blut-Hirn-Schrankenstoerung nach, bringt aber keine therapeutisch relevanten Informationen. Sie sollte waehrend der Schwangerschaft vermieden werden. Ein frueher und gezielter Einsatz der MRT bei unklaren oder verdaechtigen neurologischen Symptomen waehrend der Schwangerschaft ist sinnvoll. Die MRT unterstuetzt die Differentialdiagnose in bezug auf nicht schwangerschaftsbezogene zerebrale Leiden und kann fuer die Therapie richtungweisend sein, wenn die Gestose noch nicht ausgepraegt ist.

    Assessing the pathology of the synovium, its thickening and increased vascularity through ultrasound and magnetic resonance examinations (more often an ultrasound study alone) is still considered a sensitive parameter in the diagnosis of rheumatoid arthritis and in monitoring of treatment efficacy. Magnetic resonance studies showed that, aside from the joint pannus, the subchondral bone tissue constitutes an essential element in the development of rheumatoid arthritis. Bone marrow edema correlates with inflammation severity, joint destruction, clinical signs and symptoms of rheumatoid arthritis, and thus is considered a predictor of rapid radiological progression of the disease. The newest studies reveal that bone marrow edema may be a more sensitive indicator of the response to therapy than appearance of the synovium. Bone marrow edema presents with increased signal in T2-weighted images, being most visible in fat saturation or IR sequences (STIR, TIRM). On the other hand, it is hypointense and less evident in T1-weighted images. It becomes enhanced (hyperintense) after contrast administration. Histopathological studies confirmed that it is a result of bone inflammation (osteitis/osteomyelitis), i.e. replacememt of bone marrow fat by inflammatory infiltrates containing macrophages, T lymphocytes, B lymphocytes, plasma cells and osteoclasts. Bone marrow edema appears after a few weeks from occurrence of symptoms and therefore is considered an early marker of inflammation. It correlates with clinical assessment of disease activity and elevated markers of acute inflammatory phase, i.e. ESR and CRP. It is a reversible phenomenon and may become attenuated due to biological treatment. It is considered a “herald” of erosions, as the risk of their formation is 6-fold higher in sites where BME was previously noted

    Periodontal medicine defines a rapidly emerging branch of Periodontology focusing on establishing a strong relationship between periodontal health and systemic health. It is speculated that the major common dysregulation which links Periodontitis with Rheumatoid arthritis (RA) is being played by the mediators of immune inflammatory response. To determine whether there is any relationship between periodontal disease and Rheumatoid arthritis. A total of 100 patients were included for the present study which was divided into two groups: one group (cases) included 50 patients attending the Department of Orthopedics, Kasturba Medical College, Manipal who were diagnosed of Rheumatoid arthritis. Another subject population included 50 patients as controls attending the Department of Oral Medicine, Manipal College of Dental Sciences, Manipal with age and gender matched with those of rheumatoid arthritis group. Specific measures for periodontitis included plaque index, gingival index, number of missing teeth, and radiographic alveolar bone loss scores. Measures of rheumatoid arthritis included health assessment questionaires, levels of C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR). Various periodontal parameters were compared between the cases and controls. The average alveolar bone loss was statistically more severe in Rheumatoid arthritis (RA) group than in the controls although there were similar plaque index in both the groups. The gingival index was statistically higher in the RA group. The Erythrocyte Sedimentation Rate (ESR) and C- Reactive Protein (CRP) levels of RA patients were also significantly associated with the severity of periodontal disease. There was a significant association between Rheumatoid arthritis and Periodontitis which may be due to a common underlying deregulation of the inflammatory response in these individuals.

    1991-01-01

    The US Environmental Protection Agency's Biogenic Emissions Inventory System (BEIS) has been adapted for use on IBM-compatible personal computers (PCs). PC-BEIS estimates hourly emissions of isoprene, α-pinene, other monoterpenes, and unidentified hydrocarbons for any county in the contiguous United States. To run the program, users must provide hourly data on ambient temperature, relative humidity, wind speed, cloud cover, and a code that identifies the particular county. This paper provides an overview of the method used to calculate biogenic emissions, shows an example application, and gives information on how to obtain a copy of the program

    Objective was to describe the radiographic cervical spine changes in rheumatoid arthritis patients.Forty-nine patients (37 females and 12 males ) diagnosed with rheumatoid arthritis at King Khalid University Hospital, Riyadh, Kingdom of Saudi Arabia between June 1998 and December 2000, were studied for their radiographic cervical spine changes . Their mean age at disease onset was 41.4 + 13.4 years (range of 18-73)and mean duration of disease was 9.1+-6.28 years (range of 2-34). Their demographic data including rheumatoid factor status was obtained. Standard conventional radiographs cervical spine were obtained to study the cervical spine changes. Cervical radiographic changes were found in 34 patients (27 females and 7 males) 10 had subluxation (7 with atlanto-axial subluxation,2 with sub-axial subluxation,and one with lateral subluxation ). No vertical impaction was seen. Erosion of odontoid process was seen in one patient .All were rheumatoid seropositive Cervical spine changes in patients with rheumatoid arthritis are common, in particular subluxation in the upper cervical spine. Our study showed somewhat lesser prevalence of these changes. These were clinically correlated with disease duration, female sex, and rheumatoid factor, but were not clinically significant. (author)

    Aims This study aimed to compare the clinical outcomes of rotator cuff repair in patients with rheumatoid arthritis with those of patients who have no known history of the disease. We hypothesised that the functional outcomes are comparable between patients and without rheumatoid arthritis and may be affected by the level of disease activity, as assessed from C-reactive protein (CRP) level and history of systemic steroid intake. Patients and methods We conducted a retrospective review of the institutional surgical database from May 1995 to April 2012. Twenty-nine patients with rheumatoid arthritis who had rotator cuff repair were enrolled as the study group. Age, sex, and tear size matched patients with no disease who were selected as the control group. The mean duration of follow-up was 46 months (range 24-92 months). Clinical outcomes were assessed with the American Shoulder and Elbow Surgeons (ASES) questionnaire, Constant score and visual analogue scale (VAS). All data were recorded preoperatively and at regular postoperative follow-up visits. CRP was measured preoperatively as the disease activity marker for rheumatoid arthritis. Medication history was thoroughly reviewed in the study group. Results In patients with rheumatoid arthritis, all shoulder functional scores improved after surgery (ASES 56.1-78.1, Constant 50.8-70.5 and VAS 5.2-2.5; P rheumatoid arthritis was comparable to that of the control group (difference with control: ASES 78.1 vs. 85.5, P = 0.093; Constant 70.5 vs. 75.9, P = 0.366; VAS 2.5 vs. 1.8, P = 0.108). Patients with rheumatoid arthritis who had an elevated CRP level (> 1 mg/dl) showed inferior clinical outcomes than those with normal CRP levels. Patients with a history of systemic steroid intake showed inferior functional outcomes than those who had not taken steroids. Conclusions Surgical intervention for rotator cuff tear in patients with rheumatoid arthritis improved the shoulder functional outcome comparable to that in

    Full Text Available Die etablierte Therapie der neurogenen Detrusorhyperaktivität bei Kindern besteht in der Gabe von Anticholinergika und begleitendem intermittierendem Einmalkatheterismus. Eine hohe Nebenwirkungsrate der Anticholinergika oder eine nicht ausreichende Dämpfung der Detrusoraktivität limitiert jedoch die Anwendung und zwingt nicht selten zu einem operativen Vorgehen. Wir untersuchten deshalb die Wirksamkeit von Botulinumtoxin-A (BTX-A auf die neurogene Detrusorhyperaktivität bei Kindern mit neurogener Blasenfunktionsstörung. Hierzu wurden 24 Kinder (11 Mädchen, 13 Jungen; 2,5–20 (Ø 11,9 Jahre mit maximalem Detrusordruck 40 cm H2O trotz anticholinerger Medikation in die Studie eingeschlossen. Nach urodynamischer Evaluierung wurden gewichtsadaptiert 85–300 U BTX-A (Botox(R zystoskopisch an 30–40 Stellen in den M. detrusor injiziert. Urodynamische Kontrollen erfolgten nach 1, 3 und 6 Monaten. Urodynamisch fand sich ein erhöhtes Reflexvolumen nach 1 Monat um +84 %, nach 3 Monaten um +68 % und nach 6 Monaten um +23 %. Entsprechend verhielten sich die Maximalkapazitäten: +35 % (nach 1 Monat, +23 % (nach 3 Monaten und +36 % (nach 6 Monaten. Die Maximaldrücke veränderten sich im o.g.

Bei 5 Kindern konnte jedoch auch mit dieser Therapie keine zufriedenstellende Drucksituation sichergestellt werden; nach der daraufhin durchgeführten Blasenaugmentation fanden sich in den Blasenresektaten histomorphologisch typische BTX-A bedingte Veränderungen, die jedoch in ihrer Ausprägung keinen signifikanten Gradienten aufwiesen. Zusammenfassend läßt sich festhalten, daß es nach Botulinumtoxin-A-Injektion in den Detrusormuskel bei der Mehrzahl der Patienten zu einer ausgeprägten und therapeutisch relevanten Verbesserung sämtlicher urodynamischer Parameter bei sehr guter Verträglichkeit des Medikamentes kommt

    Full Text Available Rheumatoid arthritis is the most common inflammatory joint disease with 1 percent prevalence in community which presents with symmetrical polyarthritis of hands with inflammatory behavior. Several studies in recent years were conducted for evaluation of inflammatory cytokines such as IL1-α (Interlukin 1α and TNF- α (Tumor necrosis factor in rheumatologic disorders including rheumatoid arthritis to find new treatment methods base to pathogenesis. In this study different serum levels of IL1-α and TNF- α in 160 rheumatoid arthritis patients with active and inactive disease and also disease with or without bone erosion are assessed. 4% of our patients had rheumatoid nodule and 70% of all patients had positive RF, IL1-α, and TNF- α levels. Active with bone erosion patients had IL1-α and TNF- α serum levels higher than active without bone erosion patients; it was not significant in T-test but it was significant in Mann-Whitney Test. The results was the same as expected; IL1-α, and TNF- α serum levels were higher in active with bone erosion in comparison with inactive without bone erosion patients.

    To describe and understand the meaning of living with persistent rheumatoid arthritis. A considerable number of patients with rheumatoid arthritis live with an ongoing active and symptomatic illness despite access to potent antirheumatic treatment. There is, however, a lack of knowledge about the meaning of living with this severe long-term illness, defined as persistent rheumatoid arthritis. A descriptive design based on a hermeneutic phenomenological method was used. Ten adults with persistent rheumatoid arthritis and at least five years disease duration were interviewed. The interviews were analysed according to van Manen's method. Living with persistent rheumatoid arthritis revealed four overall themes: an existence dominated by painful symptoms and treatment, radical changes and limitations in one's life, a continual struggle to cope with one's life and to master the illness, and a dependency on those who are close by and the world around. The lifeworld was affected to a varying extent and in various ways by the illness but also by the dependence on its treatment and care that was not experienced as sufficiently meeting needs in terms of security, access to and coordination of care as well as team and rehabilitation services. Persistent rheumatoid arthritis and its treatment entail a radical effect on the person's life and quality of life. Current ordinary rheumatology care does not seem to meet the individual needs of the person with persistent rheumatoid arthritis in an optimal way. A greater knowledge about and understanding of the person who lives with persistent rheumatoid arthritis is important for facilitating the development of care and the relief of suffering. A holistic alternative to conventional clinical practice, such as person-centred care, could be tested as an innovative model of care. Our findings might serve as material for educational and counselling purposes for healthcare professionals. © 2016 John Wiley & Sons Ltd.

    Full Text Available Characterization and understanding of gut microbiota has recently increased representing a wide research field, especially in autoimmune diseases. Gut microbiota is the major source of microbes which might exert beneficial as well as pathogenic effects on human health. Intestinal microbiome’s role as mediator of inflammation has only recently emerged. Microbiota has been observed to differ in subjects with early rheumatoid arthritis compared to controls, and this finding has commanded this study as a possible autoimmune process. Studies with intestinal microbiota have shown that rheumatoid arthritis is characterized by an expansion and/or decrease of bacterial groups as compared to controls. In this review, we present evidence linking intestinal dysbiosis with the autoimmune mechanisms involved in the development of rheumatoid arthritis.

    Pertechnetate (sup(99m)TcO 4 - ) joint scintigraphy was performed on 45 patients with rheumatoid arthritis, 3 with nonspecific arthritis and 6 normal subjects. 1) The sites of radioisotopic accumulation were generally in agreement with those of clinical involvement in rheumatoid arthritis. 2) By analysis of build-up curves in the wrist joint, tracer was found to be concentrated more rapidly in rheumatoid arthritis (T 1/2 = 0.67 min.) than in nonspecific arthritis (T 1/2 = 2.66 min.) 3) The degree of radioisotopic accumulation correlated well with the value of CRP and erythrocyte sedimentation rate. It could be cosidered that pertechnetate joint scintigraphy is useful for clinical evaluation of rheumatoid arthritis. (author)

    Rheumatoid arthritis (RA) is an inflammatory disease causing pain, swelling, stiffness, and loss of function in joints; it is difficult to diagnose in early stages. An early diagnosis and treatment can delay the onset of severe disability. Infrared (IR) imaging offers a potential approach to detect changes in degree of inflammation. In 18 normal subjects and 13 patients diagnosed with Rheumatoid Arthritis (RA), thermal images were collected from joints of hands, wrists, palms, and knees. Regions of interest (ROIs) were manually selected from all subjects and all parts imaged. For each subject, values were calculated from the temperature measurements: Mode/Max, Median/Max, Min/Max, Variance, Max-Min, (Mode-Mean), and Mean/Min. The data sets did not have a normal distribution, therefore non parametric tests (Kruskal-Wallis and Ranksum) were applied to assess if the data from the control group and the patient group were significantly different. Results indicate that: (i) thermal images can be detected on patients with the disease; (ii) the best joints to image are the metacarpophalangeal joints of the 2nd and 3rd fingers and the knees; the difference between the two groups was significant at the 0.05 level; (iii) the best calculations to differentiate between normal subjects and patients with RA are the Mode/Max, Variance, and Max-Min. We concluded that it is possible to reliably detect RA in patients using IR imaging. Future work will include a prospective study of normal subjects and patients that will compare IR results with Magnetic Resonance (MR) analysis.

    Microvascular changes are one of the first obvious steps in numerous inflammatory diseases such as rheumatoid arthritis (RA). Nailfold video capillaroscopy (NFC) is an easy, reliable and safe method for evaluating peripheral microangiopathy. The objective of this study was to examine nailfold microcirculation in RA patients, assess morphological and structural changes quantitatively and qualitatively, and recognize useful changes. A total of 430 patients diagnosed with RA were examined in a period of 4 years. NFC was performed on all fingers of both hands in each patient. Different parameters indicating microvascular changes were detected and analyzed; such as microvascular architecture, capillary distribution disturbances, capillary morphology, capillary density, efferent/afferent limb ratio, subpapillary venular plexus and morphological abnormalities. The obtained results were categorized into normal pattern, nonspecific morphological abnormality and scleroderma pattern. The mean age of participants was 51.03±14.54 (19-87 years) that consisted of 359 females and 71 males. Based on the findings, angiogenesis (74.7%) was the most pathological condition observed after tortuosity (99.5%). 7.2% and 20.9% of patients were categorized into normal and scleroderma pattern group, respectively. Among morphological abnormalities, angiogenesis, isolated enlarged loop, irregular enlarged loop and architectural derangement were significantly more frequent in scleroderma than normal pattern (p<0.001). NFC may play an important role in monitoring RA disease and patients' follow-up. Therefore, in our opinion it could be considered in the course and follow-up of rheumatoid arthritis.

    In this study, we propose a regional ionospheric model (RIM) based on both of the GPS-only and the combined GPS/BeiDou observations for single-frequency precise point positioning (SF-PPP) users in Europe. GPS/BeiDou observations from 16 reference stations are processed in the zero-difference mode. A least-squares algorithm is developed to determine the vertical total electron content (VTEC) bi-linear function parameters for a 15-minute time interval. The Kriging interpolation method is used to estimate the VTEC values at a 1 ° × 1 ° grid. The resulting RIMs are validated for PPP applications using GNSS observations from another set of stations. The SF-PPP accuracy and convergence time obtained through the proposed RIMs are computed and compared with those obtained through the international GNSS service global ionospheric maps (IGS-GIM). The results show that the RIMs speed up the convergence time and enhance the overall positioning accuracy in comparison with the IGS-GIM model, particularly the combined GPS/BeiDou-based model.

    Full Text Available Bei der Realisierung digitaler Schaltungen mit einem ASIC oder FPGA kann die Wortbreite der Berechnungen frei gewählt werden. Um die Fläche bzw. die benötigte Hardware zu minimieren, wird versucht, die Berechnungen mit minimaler Wortbreite zu implementieren. Dabei muss jedoch das Quantisierungsrauschen, das durch das Beschränken der Wortbreite entsteht, berücksichtigt werden. Häufig wird hierzu eine worst-case Abschätzung des Fehlers gemacht oder mit Simulationen die benötigte Wortbreite bestimmt. Der vorliegende Beitrag betrachtet die Auswirkungen der Quantisierung analytisch. Dabei wird von gleichverteilten Eingangssignalen ausgegangen. Es wird das Quantisierungsrauschen in Abhängigkeit von der Eingangs- und Ausgangswortbreite bei der Multiplikation und beim Skalarprodukt betrachtet.

    Plain-film radiography is an important and basic element in the assessment of inflammatory rheumatic diseases. Its various uses include assessment of inflammatory osseous destruction and the activity of inflammatory changes. Furthermore, the inflammatory collateral phenomena can indicate an acute clinical phase, and the articular soft tissue swelling and tenosynovitis are shown directly and indirectly very clearly. On the other hand, high-resolution computed tomography is very capable of showing cortical structures of bone complementary to MR. In some special clinical questions and anatomical regions, especially the axial skeleton, it delivers information of high specifity, partly for definitive diagnosis and partly for planning surgical procedures. The assessment of changes in the sacroiliac joints, sternoclavicular joints and craniocervical junction are domains of computed tomography. (orig.) [Deutsch] Das konventionelle Roentgenbild muss auch heute noch bei klinischer Frage nach entzuendlich-rheumatischer Erkrankung als Basisuntersuchung angesehen werden. Sein Informationspotential umfasst nicht nur knoecherne entzuendliche Destruktionen, sondern es laesst auch deren derzeitige Aktivitaet beurteilen. Weiterhin vermag das Roentgenbild ueber die Kollateralphaenomene auf eine klinische Schubsituation hinzuweisen und die entzuendliche Volumenvermehrung der Gelenke und Sehnenscheiden direkt und indirekt darzustellen. Darueber hinaus bietet die hochaufloesende Computertomographie, insbesondere durch die detaillierte Darstellung kortikaler knoecherner Strukturen - komplementaer zur MR -, bei einigen speziellen Fragestellungen, insbesondere am Stammskelett und an einzelnen grossen Gelenken, hochspezifische Informationen, teils zur definitiven Diagnosestellung, teils auch fuer die Operationsplanung. Dies gilt u.a. fuer die Kreuzdarmbeingelenke, die Sternoklavikulargelenke und die obere HWS. (orig.)

    Rheumatoid arthritis is a chronic, multisystemic disease. The characteristic feature is persistent inflammatory synovitis. The knee joint is commonly involved with synovial hypertrophy, chronic effusion, and frequently ligamentous laxity. Pain and swelling behind the knee may be caused by extension of inflamed synovium into the popliteal space (Baker`s cyst). Plain radiographs of the knee joint remain the basic radiological procedure, although early in the disease they might not provide significant changes. Sonography sufficiently reveals synovial fluid and Baker cysts, but cannot be recommended for evaluation of synovial proliferations or pannus formation. Computer tomography has only limited indications and may be used for the evaluation of subtle erosive lesions or the quantitation of osteoporotic changes. Magnetic resonance imaging has shown excellent visualization of cartilage, fluid, synovium and soft tissues and is the method of choice for the demonstration of early affection and the evaluation of panus activity and therapy control. With daministration of contrast agents (gadolinium), dynamic studies may demonstrate inflammatory activity. Modern MR sequences, such as T1 SE `fat sat` or magnetization transfer, further improve the discrimination of cartilage, pannus and synovial fluid. (orig.) [Deutsch] Die chronische Polyarthritis (CP) ist eine multisystematische Erkrankung und wird charakteristischerweise von einer persistierenden inflammatorischen Synovitis begleitet. Das Kniegelenk ist das haeufigste einzeln betroffene Gelenk, seine Affektion manifestiert sich zumeist mit synovialer Hypertrophie, chronischen Erguessen und oftmals auch Bandinstabilitaet. Schmerzen sowie Schwellungen in den dorsalen Weichteilen sind oft durch Vordringen inflammatorischer Synovia oder Ergussansammlungen bedingt (Baker-Zyste). Das konventionelle Roentgenbild bildet zwar einen Grundpfeiler in der CP-Diagnostik, zeigt jedoch oft erst bei fortgeschrittenem Krankheitsverlauf

  18. Solution Method and Precision Analysis of Double-difference Dynamic Precise Orbit Determination of BeiDou Navigation Satellite System

    2016-02-01

    Full Text Available To resolve the high relativity between the transverse element of GEO orbit and double-difference ambiguity, the classical double-difference dynamic method is improved and the method, which is to determine precise BeiDou satellite orbit using carrier phase and pseudo-range smoothed by phase, is proposed. The feasibility of the method is discussed and the influence of the method about ambiguity fixing is analyzed. Considering the characteristic of BeiDou, the method, which is to fix double-difference ambiguity of BeiDou satellites by QIF, is derived. The real data analysis shows that the new method, which can reduce the relativity and assure the precision, is better than the classical double-difference dynamic method. The result of ambiguity fixing is well by QIF, but the ambiguity fixing success rate is not high on the whole. So the precision of BeiDou orbit can't be improved clearly after ambiguity fixing.

    Aim: Recent in-vitro and in-vivo studies demonstrated a somatostatin receptor expression in some non-medullary thyroid carcinomas. In this study we investigated the somatostatin receptor status for this particular tumor entity in a larger patient group. Subject and methods: We compared 131-iodine with 111-In-pentetreotide scans in 24 patients with metastasizing, non-medullary thyroid cancer. The findings were correlated with other imaging modalities. Additionally, we performed receptor autoradiography in one patient, octreotide therapy in another patient and administration of 90-Y- and 111-In-DOTATOC in 2 consecutive patients. Results: In the 15 patients with papillary or follicular carcinoma, 111-In-pentetreotide was inferior to 131-I in 8/15, equal in 1/15, and superior in 6/15 patients. In 8/9 of the patients with Huerthle cell cacinoma, metastases showed a 111-In-pentetreotide accumulation of various intensity, while 131-iodine scans were negative except for one patient. 111-In-pentetreotide was equal or superior compared to 201-Tl or 99m-Tc-sestamibi, but for the most part inferior in comparison with 18-F-FDG-PET. The findings of 111-In-pentetreotide scintigraphy correlated well with the receptor autoradiography and the accumulation of DOTATOC, but not with the therapeutic effect of `cold` octreotide on the thyroid cancer metastases. Conclusions: Several metastases of papillary and follicular carcinoma, and the majority of Huerthle cell cancer metastases can express somatostatin receptors. 111-In-pentetreotide scintigraphy is a promising tool for localization of metastases especially in Huerthle cell cancer or if PET is not available, and may be useful for selection of possible candidates, if therapeutic effective {beta}-emitting somatostatin analogues will be available for routine application.

    Purpose: To differentiate between urodynamically relevant obstruction and functionally unimportant dilation of the upper urinary tract in patients with neobladder using a modified furosemide urogram. Method: An excretory urogram with furosemide loading was carried out in 19 patients with neobladder and sonographically and urographically confirmed dilation of the upper urinary tract. Once strong contrasting of the renal pelves and calyces has been achieved, 20 mg of furosemide were applied and late radiographs were obtained at 15 min and 30 min, respectively. An obstruction was defined as increasing dilation of the renal pelves and calices during forced diuresis and lack of washout effect of the contrast medium. Results: In 32 cases, the renoureteral unit (RUU) was dilated on ultrasound. Of these, 25 RUU`s showed good emptyness of contrast medium upon stimulation of diuresis, six RUU`s returned a borderline findings, while one RUU was found to exhibit a decompensated anastomotic stenosis, which was dilated. Two further patients with bordeline findings were later treated surgically due to their pain symptoms. No patient required further preoperative diagnostic procedures. Conclusions: The modified furosemide urogram represents a cost-effective diagnostic orientation strategy in patients with neobladder and dilated renal pelves and calyses and is both well-tolerated by patients and meets with broad acceptance from the urologic staff.

    Purpose: To investigate highly temporally resolved MR-angiography (MRA) with time-resolved imaging with stochastic trajectories (TWIST) of the hand as supplementary tool for dynamic assessment of synovitis and vascular pathologies in rheumatoid diseases. Material and methods: A coronal dynamic TWIST–MRA-sequence (0.7 mm × 0.7 mm × 1.4 mm, temporal resolution 2.5 s, time of acquisition 4 min) of the predominantly affected hand of 17 patients with suspected rheumatoid disease was acquired after contrast administration (Multihance, Bracco Imaging SpA) at 3 T (Magnetom VERIO, 8-channel-knee-coil, Siemens Healthcare). As standard of reference, contrast enhanced non fat-saturated coronal and fat-saturated axial T1-w sequences were acquired. These static sequences and the dynamic TWIST–MRA–maximum-intensity-projections (MIP) were separately assessed by two readers in consensus, recording the number of synovial lesions (wrist, intercarpal, metacarpophaleangal/proximal/distal interphalangeal joints), signs of tenosynovitis and vasculitis. Diagnostic confidence was rated (4-point-scale: 4 = excellent; 1 = non-diagnostic). Statistical significance was tested using the Wilcoxon-rank-sum-test. Results: An insignificantly lower number of synovial lesions (n = 72 vs. 89; p = 0.1) and only 3/9 cases with tenosynovitis were identified by the TWIST–MRA. For detected lesions, diagnostic confidence was comparable (MRA: 3.64; static T1-w post contrast: 3.47). In patients with high clinical activity dynamic MRA showed very early synovial enhancement. Only dynamic MRA detected 3 cases of vasculitis (subsequently confirmed with digital-subtraction-angiography). Conclusion: TWIST–MRA facilitates fast detection of synovitis. Although dynamic MRA of the hand is inferior to static contrast enhanced sequences in assessing the number of synovitic and tenosynovitic lesions, its high temporal resolution allows for fast visual grading of disease activity and assessment of vasculitis

    Arthritis gloves are regularly provided as part of the management of people with rheumatoid arthritis (RA) and undifferentiated (early) inflammatory arthritis (IA). Usually made of nylon and elastane (i.e. Lycra®), these arthritis gloves apply pressure with the aims of relieving hand pain, stiffness and improving hand function. However, a systematic review identified little evidence supporting their use. We therefore designed a trial to compare the effectiveness of the commonest type of arthritis glove provided in the United Kingdom (Isotoner gloves) (intervention) with placebo (control) gloves (i.e. larger arthritis gloves providing similar warmth to the intervention gloves but minimal pressure only) in people with these conditions. Participants aged 18 years and over with RA or IA and persistent hand pain will be recruited from National Health Service Trusts in the United Kingdom. Following consent, participants will complete a questionnaire booklet, then be randomly allocated to receive intervention or placebo arthritis gloves. Within three weeks, they will be fitted with the allocated gloves by clinical specialist rheumatology occupational therapists. Twelve weeks (i.e. the primary endpoint) after completing the baseline questionnaire, participants will complete a second questionnaire, including the same measures plus additional questions to explore adherence, benefits and problems with glove-wear. A sub-sample of participants from each group will be interviewed at the end of their participation to explore their views of the gloves received. The clinical effectiveness and cost-effectiveness of the intervention, compared to placebo gloves, will be evaluated over 12 weeks. The primary outcome measure is hand pain during activity. Qualitative interviews will be thematically analysed. This study will evaluate the commonest type of arthritis glove (Isotoner) provided in the NHS (i.e. the intervention) compared to a placebo glove. The results will help

    Full Text Available Festliche Preisverleihungen sind Gelegenheiten, bei denen von den Preisträgerneine kurze Rede erwartet wird. Obwohl die Dankesrede eine kleinere Randgattung innerhalb des epideiktischen Genres ist, steht sie im Mittelpunkt des Ereignisses. Rhetorikhandbücher geben zahlreiche Ratschläge, wie eine gute Festrede vorbereitet werden soll, um zu unterhalten, zu bewegen und zu belehren. Ziel dieser Untersuchung ist es festzustellen, welche Eigenschaften der Dankesrede die Zuhörer als erwünscht oder unerwünscht wahrnehmen und welche Charakteristika am meisten zur Qualität festlicher Dankesreden beitragen. Das Korpus der gesprochenen Texte bilden 30 Dankesreden anlässlich kroatischer Preisverleihungen in den Bereichen Schauspiel, Sport, Musik, Fernsehen, Literatur und Wirtschaft. Die Audio-Aufnahmen der Dankesreden wurden einer Gruppe von Hörern zur Bewertung in folgenden Kategorien vorgelegt: interessant, geistreich, hoher Sprachstil, feierlich, emotiv, persönlich, originell, bescheiden, vorbereitet und spontan. Zusätzlich wurde zu jeder Rede die offene Frage gestellt, was dem Zuhörer an der Rede gefallen oder nicht gefallen habe. Die Resultate der Perzeptionsanalye lassen erkennen, dass die Interessantheit einer Rede mit der Eigenschaft des Geistreichen, des Originellen, des Emotionalen und des Persönlichen in Verbindung gebracht wird und die Eigenschaft des Festlichen im Wesentlichen nur mit dem hohen Sprachstil und der Vorbereitetheit des Textes korreliert. Einige Eigenschaften können sowohl erwünscht als auch unerwünscht sein, z. B. Dialekt, Persönliches und Kürze. Die besten Dankesreden haben Eigenschaften, die im Grunde schwer miteinander zu verbinden sind: Einerseits soll der Text vorbereitet sein (hoher Stil, Wortwahl, Figuren, Originalität der Geschichte, Humor, andererseits wird bei der Ausführung Spontaneität (Aufrichtigkeit, Emotionalität, Persönlichkeit erwartet.

    Bei der (18) F-Fluordeoxyglucose-Positronenemissionstomographie/Computertomographie (FDG-PET/CT) ergeben sich häufig Zufallsbefunde. In der vorliegenden Studie konzentrierten wir uns auf mittels FDG-PET/CT erhaltene Zufallsbefunde bei Patienten mit kutanem Melanom und überprüften deren Relevanz hinsichtlich weiterer diagnostischer Maßnahmen und Interventionen. Die Krankenakten von 181 konsekutiven Melanom-Patienten wurden retrospektiv ausgewertet, um das Management von Zufallsbefunden zu dokumentieren. Der Schwerpunkt lag dabei auf den histologischen Befunden. Bei 33 von 181 (18 %) Patienten lagen 39 relevante Zufallsbefunde vor, und zwar im Kolorektalbereich (n = 15 Patienten), in der Schilddrüse (n = 8), der Prostata (n = 2), dem Bewegungsapparat (n = 2), in Lymphknoten (n = 2), der Parotis (n = 1), den Mandeln (n = 1), den Nieren (n = 1) und der Gallenblase (n = 1). Bei 25 Patienten schlossen sich weitere diagnostische Verfahren an, wobei in 21 Fällen ein klinisches Korrelat nachgewiesen wurde. Bei 16 von 21 Patienten ergab sich eine Neoplasie, darunter fünf maligne Läsionen (vier Kolonkarzinome und ein Prostatakarzinom). Die Malignome wurden frühzeitig diagnostiziert und in der Mehrzahl der Fälle erfolgreich entfernt. Der Einsatz der FDG-PET/CT als Routine-Diagnostik wird in den Leitlinien empfohlen und ist indiziert bei malignem Melanom ab Stadium IIC. In dieser Studie wurden auf effektive Weise ansonsten nicht erkannte Krebserkrankungen, insbesondere Kolonkarzinome, detektiert. In den meisten Fällen war eine frühe Intervention möglich. Zufallsbefunde durch FDG-PET/CT sollten, unter Berücksichtigung des Zustands und der Wünsche des Patienten, mit den geeigneten diagnostischen Maßnahmen abgeklärt werden. © 2016 Deutsche Dermatologische Gesellschaft (DDG).

    Alitretinoin ist die einzige zugelassene Behandlung für schweres chronisches Handekzem (CHE), das refraktär gegenüber potenten topischen Corticosteroiden ist. Bei dieser Studie (FUGETTA) wurde die Wirksamkeit von leitliniengerecht angewendetem oralem Alitretinoin sowie dessen Einfluss auf die Lebensqualität (LQ) bei Patienten mit schwerem refraktärem CHE beurteilt. Multizentrische, offene, nichtinterventionelle Beobachtungsstudie, durchgeführt in Deutschland. Die Patienten wurden nach Ermessen ihres behandelnden Arztes mit Alitretinoin 10 mg oder 30 mg einmal täglich über maximal 24 Wochen behandelt. Die Wirksamkeit wurde anhand des Physician Global Assessment (PGA) und des Dermatology Life Quality Index (DLQI) bewertet. Zudem wurden unerwünschte Ereignisse (UE) erfasst. Die Studienpopulation bestand aus 658 Patienten (30 mg: n = 581; 10 mg: n = 77). Bei Beobachtungsbeginn litten die meisten Patienten (83 %) gemäß PGA an einem schweren CHE. Bei Beobachtungsende war das Handekzem bei 48 % der Patienten gemäß PGA vollständig oder fast vollständig abgeheilt (30 mg: 49 %; 10 mg: 43 %). Die mittlere Verbesserung des DLQI-Scores in Woche 24 betrug 58 % (30 mg: mittlere [SD] Veränderung gegenüber dem Ausgangswert -10,4 [8,04]) und 70 % (10 mg: mittlere [SD] Veränderung gegenüber dem Ausgangswert -10,8 [7,29]). Die Gesamtinzidenz von NW war niedrig und in den beiden Gruppen ähnlich. Alitretinoin führte zu einer schnellen, deutlichen Verbesserung der LQ bei Patienten mit schwerem CHE. © 2016 Deutsche Dermatologische Gesellschaft (DDG). Published by John Wiley & Sons Ltd.

    241 patients suffering from myalgic symptoms were examined by axial scans of the muscular system with T1w and STIR-sequences. All patients underwent a complete neuromuscular examination, which included an MRI guided muscle-biopsy of 203 patients. The images were retrospectively analysed as to the typical characteristics of differential diagnosis. In cases of idiopathic or bacterial/viral induced myositis, primary vasculitis, and rhabdomyolysis, edematous changes of the muscles could always be found. Abscesses were only found in bacterial myositis. In cases of poly- and dermatomyositis as well as inclusion-body-myositis, MRI showed a uniform distribution pattern with emphasis on the quadriceps muscles. In contrast to other neuromuscular diseases in bacterial induced myositis, focal myositis, and rhabdomyolysis a strong contrast agent enhancement was seen. All patients with myalgic syndromes without any other additional neuropathological findings and 86% of the patients suffering from polymyalgia rheumatica had normal MR-findings. MRI allows a correct exclusion of an inflammatory, tumorous, or rhabdomyolitic cause of a myalgia and leads to pathognomonic findings for these diseases. Diseases belonging to the group of endocrine, toxic, or metabolic myopathies might be normal in MRI.

    Plain films and direct magnification radiographs of the hands were performed in 34 patients affected by rheumatoid arthritis, using mammographic x-ray tube, achieved with 0.1 mm microfocus, and 1.85 x magnification factor. Direct magnification radiography has provided essential or useful diagnostic data in 44% of cases, particularly in recognizing early skeletal erosions. Nevertheless direct magnification radiography must be used only in those cases in which traditional mammographic techniques do not supply sactisfactory results.

    Magnetic resonance spectroscopy is a noninvasive investigative technique for in vivo detection of biochemical changes in neuropsychiatric disorders for which especially proton ({sup 1}H-MRS) and phosphorus ({sup 31}P-MRS) magnetic resonance spectroscopy have been used. In this review we explain the principles of MRS and summarize the studies in schizophrenia. A systematic literature review was carried out for {sup 1}H-MRS studies investigating schizophrenic patients compared to controls. The inconsistent results in the cited studies may be due to different study population, specific neuroimaging technique, and selected brain regions. Frequent findings are decreased PME and increased PDE concentrations ({sup 31}P-MRS) linked to altered metabolism of membrane phospholipids and decreased N-acetylaspartate (NAA) or NAA/choline ratio ({sup 1}H-MRS) linked to neuronal damage in frontal (DLPFC) or temporal regions in patients with schizophrenia. These results contribute to the disturbed frontotemporal-thalamic network assumed in schizophrenia and are supported by additional functional neuroimaging, MRI morphometry, and neuropsychological evaluation. The combination of the described investigative techniques with MRS in follow-up studies may provide more specific clues for understanding the pathogenesis and disease course in schizophrenia. (orig.)

    Radiographs were reviewed in a group of nine patients with classical seropositive rheumatoid arthritis who on tissue typing were found to express the class I HLA-B27 allele. Radiographs were analyzed with regard to whether or not they demonstrated radiographic features of (1) classical rheumatoid arthritis, (2) seronegative arthritis, or (3) mixed features of rheumatoid and seronegative arthritis. Five patients (55%) displayed radiographic features consistent with a diagnosis of rheumatoid arthritis, two patients (22%) showed radiographic features of seronegative disorder (periostitis and sacroiliitis), and two patients (22%) showed a mixed picture with evidence of both rheumatoid arthritis and a seronegative disorder. Thus, the HLA-B27 allele contributed to the radiographic features in 44% of patients with rheumatoid arthritis and associated HLA-B27. Thus, the wide range of findings in our population indicates that the radiographic attributes are not specific enough to constitute a unique subpopulation of patients with rheumatoid arthritis.

    Proton induced X-ray emission (PIXE) analysis is used to measure trace element concentrations in blood serum from patients with rheumatoid arthritis. Initially trace element contaminations in blood-collecting and storing devices are determined. Then mean values and nyctemeral cycles are measured both in normal subjects and patients with rheumatoid arthritis and other similar pathologies. Abnormal concentrations of Cu and Zn and anomalies in the nyctemeral cycle are found in the patients. In the second phase of the project, the special case of chrysotherapeutically treated (gold salt treatment) rheumatoid arthritis patients is studied for extended periods of time (up to 53 weeks).

    For the study of the temporomandibular joint in rheumatoid arthritis 30 patients were selected who were diagnosis as rheumatoid arthritis through the clinical, radiographic examination and laboratory finding. Temporoman dibular joint involvement was evaluated through the clinical, radiographic examination. The results were as follows; 1. TMJ was involved in 15 patients of 30 patients with rheumatoid arthritis. (50% involvement). 2. Duration of rheumatoid arthritis was more longer in patients with TMJ involvement than in patients without TMJ involvement. 3. Osseous changes in TMJ were in order of frequency erosion, flattening, osteophyte, sclerosis, deformity, and most common involved site was mandibular condyle. 4. Most common positional change of condyle was forward position in centric occlusion, and restricted movement of condyle in 1 inch mouth opening. 5. TMJ involvement of rheumatoid arthritis was almost bilateral. 6. Main symptoms of TMJ were pain, stiffness, tenderness, limitation of mouth opening, crepitation. 7. There was not the case of ankylosis. 8. There was statistically insignificant correlation between mandibular deviation and TMJ involvement, but some cases showed severe deviation on mouth opening.

    Angiogenesis, as well as pannus formation within the joint, plays an important role in the erosion of articular cartilage and bone in the pathological process of rheumatoid arthritis (RA). Tissue factor (TF), an essential initiator of the extrinsic pathway of blood coagulation, is also involved in the angiogenesis and the pannus formation of RA progression. In the present study, we used immunofluorescence and confocal scanning methods to characterize TF immunolocalization in RA synovium. We showed that positive staining of TF could be immunolocalized in synoviocytes, CD19(+) B cells and CD68(+) macrophages, whereas weak or negative staining of tissue factor could be found in CD34(+) endothelial cells of neo-vessels, CD3(+) T cells and CD14(+) monocytes in RA synovium tissues. Our study demonstrates a detailed local expression of TF in the rheumatoid synovium, and supports the notion that TF, expressed not only by the synoviocytes themselves, but also the infiltrating CD19(+) B cells and CD68(+) macrophages, is involved in the pannus invasion in the progression of rheumatoid arthritis.

    The study presents the results of predicting role of anti-cyclic citrullinated peptide antibodies in rheumatoid arthritis, compared to rheumatoid factor. 32 patients with rheumatoid arthritis were identified from a retrospective chart review. The results of our study show that presence of the rheumatoid factor has less diagnostic and prognostic significance than the anti-cyclic citrullinated peptide, and suggests its superiority in predicting an erosive disease course.

    A solid-phase radioimmunoassay and an enzyme-linked immunosorbent assay have been developed for the identification of IgE rheumatoid factor (IgE RF). For both, human IgG was used as antigen. Bound IgE RF was detected by means of commercially available rabbit anti-human IgE antiserum and 125 I-labelled sheep anti-rabbit IgG as well as monoclonal anti-human-ε-chain antibody and horse-radish peroxidase-labelled sheep anti-mouse IgG. The presence of IgM RF did not cause false positive results. Correlation in the results of both assays were significant, the reproducibility was very good. In 50.6% of 79 sera from patients with rheumatoid arthritis IgE RF has been detected with both or one of the methods. Only in 1 out of 12 seronegative rheumatoid arthritis sera IgE RF was identified.

    Full Text Available Rheumatoid arthritis (RA is a chronic autoimmune disease that has a significant effect on patients’ physical, emotional, and social functioning. For decades, patients have used different diets to try to improve the symptoms of RA. The possible benefits of dietary therapy for rheumatoid arthritis are reviewed in this article. Nutritional objectives for RA, are to halt the loss of bone mass, promote healing of bone fractures and improving bone-associated inflammatory disorders and joints. In general, diets low in saturated fat, rich in polyunsaturated fats: omega 3 and omega 6, rich in complex carbohydrates and fiber are recommended.

    BeiDou system navigation messages are modulated with a secondary NH (Neumann-Hoffman) code of 1 kbps, where frequent bit transitions limit the coherent integration time to 1 millisecond. Therefore, a bit synchronization algorithm is necessary to obtain bit edges and NH code phases. In order to realize bit synchronization for BeiDou weak signals with large frequency deviation, a bit synchronization algorithm based on differential coherent and maximum likelihood is proposed. Firstly, a differential coherent approach is used to remove the effect of frequency deviation, and the differential delay time is set to be a multiple of bit cycle to remove the influence of NH code. Secondly, the maximum likelihood function detection is used to improve the detection probability of weak signals. Finally, Monte Carlo simulations are conducted to analyze the detection performance of the proposed algorithm compared with a traditional algorithm under the CN0s of 20~40 dB-Hz and different frequency deviations. The results show that the proposed algorithm outperforms the traditional method with a frequency deviation of 50 Hz. This algorithm can remove the effect of BeiDou NH code effectively and weaken the influence of frequency deviation. To confirm the feasibility of the proposed algorithm, real data tests are conducted. The proposed algorithm is suitable for BeiDou weak signal bit synchronization with large frequency deviation.

    So far, there ave been few studies on measurable health effects of emissions from road traffic. An analysis of the available studies yields no clear indication of a relationship between road traffic emissions and the incidence of asthma and allergies in infants. On the other hand, there are no valid data on individual pollutant exposure of infants in the framework of epidemiological studies which take account of other influencing factors.(orig./MG) [Deutsch] Der Frag, ob eine Schadstoffbelastung durch den Strassenverkehr einen messbaren schaedigenden Effekt auf die menschliche Gesundheit hat, ist bislang in wenigen Studien nachgegangen worden.

    The goal of this study was to compare magnetic resonance (MR) image quality at different field strengths for evaluating lesions in wrist and finger joints of patients with rheumatoid arthritis (RA) in order to determine whether the higher field strength provides diagnostic gain. The hand mainly affected in 17 RA patients was examined at 1.5 Tesla (T) and 3.0 T with comparable MR imaging (MRI) protocols. MR images were reviewed twice by two experienced radiologists using the Rheumatoid Arthritis MRI Scoring System (RAMRIS) of the OMERACT (Outcome Measures in Rheumatoid Arthritis Clinical Trials) group. Image quality was rated on a five-point scale using Friedmann's test and Kendall's W-test for statistical analysis. Image comparison revealed better image quality at higher field strength. Image quality of T1-weighted images was rated 14-22% better at 3.0 T compared with 1.5 T by both readers. Moreover, the rating for the T2-weighted-images acquired at 3.0 T was one point better in the five-point scale used. Inter-reader correlation for image quality, bone erosions/defects, edema and synovitis ranged between 0.6 and 0.9 at 3.0 T and between 0.6 and 0.8 at 1.5 T. Intra-reader correlation for these parameters was high at 0.8-1.0. MRI image quality of RA hands is superior at 3.0 T, while an acceptable image quality is achieved at 1.5 T, which improves the evaluation of extent of bone edema, synovitis and identification of small bone erosions.

    This study was carried out to determine whether and to what extend radiographic erosion, joint space narrowing, and malalignment are predictive of clinical disability in patients with rheumatoid arthristis (RA). Radiographs of the hands and wrists of 224 patients with RA were scored for these radiographic parameters. To determine which of these findings best explained variation in clinical measures of disability, a series of regression analyses was performed. Malalignment scores were the best predictor of joint deformity and limitation of motion. Erosion scores were most predictive of variation in functional tests. The author concludes that specific radiographic findings of malalignment and erosion are significantly predictive of disability in patients with RA

    In modern surgical oncology, adjuvant therapies are important complementary strategies. In local advanced carcinomas of the gastrointestinal tract, 5-year survival data are still disappointing despite standardized surgery. In this context, it has to be differentiated between adjuvant therapy following complete tumor exstirpation (so-called UICC R{sub 0} resection) and additive therapies following incomplete tumor resections (UICC R{sub 1} or R{sub 2} resection). Modalities in the adjuvant setting are chemotherapy, radiotherapy or the combined radio-/chemotherapy. In esophageal and gastric cancer there is up to now no benefit of postoperative adjuvant therapy. In pancreatic cancer, there are studies indicating a benefit of combined radio-/chemotherapy after complete tumor resection. A standard adjuvant chemotherapeutic treatment is proven in colon cancer stage III (Dukes C) with levamisole and 5-FU. Completely resected rectal carcinoma should be treated postoperatively with combined radio-/chemotherapy. In the common clinical or practical setting, adjuvant therapy is indicated only in locally advanced gastrointestinal tumors following R{sub 0} resection. Postoperative therapy following incomplete tumor resection has its reason only in a palliative intention. (orig.) [Deutsch] Adjuvante Therapiestrategien sind wichtige flankierende Massnahmen der modernen onkologischen Chirurgie, da u.a. die 5-Jahres-Ueberlebensquoten bei lokal fortgeschrittenen Tumoren des Gastrointestinaltraktes nach wie vor unbefriedingend sind. Dabei muss grundsaetzlich zwischen adjuvanten Behandlungen nach kompletter Tumorexstirpation (UICC-R{sub 0}-Resektion) und der additiven Therapie nach palliativer Resektion (UICC-R{sub 1}- oder -R{sub 2}-Resektion) unterschieden werden. Als Modalitaeten kommen Chemotherapie, Strahlentherapie und ihre Kombination in Frage. Bei Oesophagus- und Magenkarzinomen kann derzeit keine gueltige Empfehlung zur adjuvanten Therapie gegeben werden. Die Radio

    Full Text Available Rheumatoid arthritis (RA is a chronic systemic inflammatory disease, characterised by polyarthritis and extra-articular organ disease, including rheumatoid nodules, ophthalmologic manifestations, cardiopulmonary disease, vasculitis, neuropathy, glomerulonephritis, Felty’s syndrome, and amyloidosis. Extra-articular manifestations of RA (ExRA occur in 17.8–40.9% of RA patients, 1.5–21.5% of them presenting as severe forms and usually associated with increased morbidity and mortality. They can develop at any time during the course of the disease, even in the early stages, and are associated with certain predisposing factors, such as the presence of rheumatoid factor, smoking, and long-standing severe disease. Rheumatoid nodules, the most common ExRA, have been found to be associated with the development of severe features, such as vasculitis, rheumatoid lung disease, pericarditis, and pleuritis, especially in those patients who develop them within 2 years from RA diagnosis. There is no uniformity in the definition of the term ExRA, which limits comparability between different studies. Several recent surveys suggest a lower frequency, probably due to a better control of disease activity. Diagnosis of ExRA is a challenge for clinicians, given its variable and complex presentation, and the lack of specific diagnostic tests; it must be based on clinical recognition and exclusion of other causes of the signs and symptoms. Furthermore, management continues to be difficult with a bad prognosis in many conditions. This article reviews the clinical aspects of major ExRA, focusing on incidence, clinical features, and therapeutic approaches, and how modern immunosuppressive therapy can change the outcome.

  19. A Fast and High-precision Orientation Algorithm for BeiDou Based on Dimensionality Reduction

    Directory of Open Access Journals (Sweden)

    ZHAO Jiaojiao

    2015-05-01

    Full Text Available A fast and high-precision orientation algorithm for BeiDou is proposed by deeply analyzing the constellation characteristics of BeiDou and GEO satellites features.With the advantage of good east-west geometry, the baseline vector candidate values were solved by the GEO satellites observations combined with the dimensionality reduction theory at first.Then, we use the ambiguity function to judge the values in order to obtain the optical baseline vector and get the wide lane integer ambiguities. On this basis, the B1 ambiguities were solved. Finally, the high-precision orientation was estimated by the determinating B1 ambiguities. This new algorithm not only can improve the ill-condition of traditional algorithm, but also can reduce the ambiguity search region to a great extent, thus calculating the integer ambiguities in a single-epoch.The algorithm is simulated by the actual BeiDou ephemeris and the result shows that the method is efficient and fast for orientation. It is capable of very high single-epoch success rate(99.31% and accurate attitude angle (the standard deviation of pitch and heading is respectively 0.07°and 0.13°in a real time and dynamic environment.

    Scintigraphic scanning employing technetium-99m sulfur colloid was used to assess the size of the liver and spleen in 32 consecutive patients with rheumatoid arthritis. The data were correlated with clinical and laboratory assessment. Seven patients had enlarged livers, three enlarged spleens. An expected correlation of liver enlargement with Sjogren's syndrome did not materialize. Splenic enlargement and liver enlargement were discordant. Liver enlargement correlation best with elevations of rheumatoid factor as measured by latex fixation. As liver enlargement is not an appreciated feature of rheumatoid arthritis, these findings suggest that hepatomegaly need not necessarily imply adverse treatment results or the development of lymphoproliferative disorders.

    The objective was to determine the clinical characteristics of rheumatoid arthritis in Saudi Arabia in relation to human leukocyte antigen type. A group of 91 rheumatoid arthritis patients, 72 females and 19 males were studied for the various clinical, laboratory and radiological parameters along with human leukocyte antigen-DR phenotypes. Since human leukocyte antigen-DR10 was most commonly associated with rheumatoid arthritis in our population, we compared those patients with human leukocyte antigen-DR10 to those without. The comparison yielded differences in the presence of rheumatoid nodules, erosions, corticosteroid treatment, and joint involvement at presentation, hemoglobin levels, and white cell count. Only the last 3 parameters showed a statistical significance. Human leukocyte antigen type of Saudi patients with rheumatoid arthritis influenced the course of the disease but only to a limited extent. (author)

    To describe the clinical characteristics, serologic, radiological and clinical disease activity, and modality of therapy in patients with rheumatoid arthritis (RA) at tertiary outpatient care in Qatar. The study design was cross-sectional where 100 consecutive cases who met 1987 American College of Rheumatology criteria for diagnosis of RA were enrolled in this study. Demographic data (sex, nationality and age) numbers of swollen and tender joints, X-rays and current medications were collected during outpatients visits to Hamad General Hospital. Disease Activity Score of 28 joints (DAS28) and Health Assessment Questionnaires (HAQ) scores were calculated. All patients with RA who were seen as rheumatology outpatients were invited to participate in the study. One hundred patients were seen and examined during their follow-up at the outpatient clinic; data were collected and analyzed. Females represented 67% of all patients, 6% had more than six swollen joints, 9% had more than six tender joints. DAS28 and erythrocyte sedimentation rate (DAS28) calculation revealed 49% of patients were in remission (DAS28  3.2.Mean HAQ score was 1.02. Rheumatoid factor (RF) was positive in 63%, while anti-cyclic citrullinated protein antibody (anti-CCP) was positive in 71%, and 49% were positive for both. Radiography of hands and feet during the previous year was done in 65% of patients: 11% of them had erosions. Sixty-six percent were on one synthetic disease-modifying anti-rheumatic drug (DMARD) and 27% where on more than one synthetic DMARD and 7% where on no DMRD. Glucocorticoids were used in 51% and 29% were on biologics. Sixty-four percent of rheumatoid arthritis patients in Qatar were in remission or had low disease activity while the remaining 36% had active disease and among these patients 29% were on biologics. © 2013 Asia Pacific League of Associations for Rheumatology and Wiley Publishing Asia Pty Ltd.

  3. Sacroiliac joint involvement in classical or definite rheumatoid arthritis

    In 188 patients with rheumatoid arthritis 564 radiologic examinations of the sacroiliac joints were performed. Severe blurring of the joint space or ankylosis were uncommon. The involvement was related to an age > 40 years at the onset, high values of the ESR and involvement of most joint groups in the limbs and cervical spine. Sex, presence or high titres of the rheumatoid factor and antinuclear antibodies were unrelated to lesions of the sacroiliac joints. A relation to the severity of rheumatoid arthritis rather than to the immunologic condition is suggested. (Auth.)

    Although IgG rheumatoid factor may play a central role in the pathogenesis of rheumatoid arthritis, previously there have been no precise methods for its specific measurement in serum and synovial fluid. This paper describes a solid phase radioimmunoassay for the independent quantification of IgM and IgG rheumatoid factor reacting with the Fc fragment of human IgG. As measured by this assay, serum IgG rheumatoid factor levels differed significantly between patients with seropositive and seronegative rheumatoid arthritis and normal control subjects. In addition, several sera and joint fluids from patients with seropositive rheumatoid arthritis, even without vasculitis, were shown by gel chromatography to have acid-dissociable complexes of IgG rheumatoid factor suggestive of IgG-IgG dimer or trimer formation

    1987-10-01

    Anticardiolipin antibody (ACA) was present in the sera of 49% of 90 consecutive patients with rheumatoid arthritis (RA). The ACA was absent in 30 control patients with osteoarthritis. C-reactive protein levels equal to or exceeding 7 mg/dl were found in 10 patients all of whom were ACA positive. ACA was present in a larger proportion of rheumatoid factor (RF) positive than of RF negative patients. Male sex and extra-articular manifestations of RA were both more common in ACA positive than ACA negative patients. In the ACA positive group the lupus anticoagulant and VDRL tests were negative. However, a small number of patients had evidence of vascular events.

    Full Text Available A terminal of Compass Navigation Satellite System (CNSS, which can not only support BeiDou-1 and BeiDou-2 but also support Global Positioning System (GPS, is designed to research the activities of the migrant birds, with our novel design of a multiband antenna. By a high-density integration, this terminal is designed with a compact size and light weight. When the terminal is assembled to a whooper swan, its flying trace is recorded by the CNSS, which is in agreement with that of GPS. The flying route map based on the CNSS is useful to check the situation and habit of the migrant bird, which is important for animal protection and bird flu outbreak prediction.

    First results of PET/CT in Hodgkin's disease (HD) and aggressive non-Hodgkin's lymphoma (NHL) are reported. From March 2001 to August 2004 822 PET/CT were performed at our clinic in lymphoma patients for primary staging, restaging after therapy, and diagnosis of recurrence. For coregistration non contrast-enhanced low-dose CT were used. Due to the exact anatomic localization of {sup 18}F-FDG accumulating lesions equivocal or false positive PET findings are avoided. In comparison to contrast enhanced CT, PET/CT has a higher sensitivity and specificity in patients with HD and aggressive NHL. Integration of PET/CT in treatment planning of radiation therapy optimizes the field volume. Even in the initial phase of clinical evaluation, PET/CT has proven useful in staging and restaging of lymphoma. The exact anatomic localization of the PET findings is essential for a precise report, for treatment planning of radiation therapy, and for planning surgical biopsy. (orig.) [German] Erste Ergebnisse der PET-CT bei Morbus Hodgkin (HD) und den aggressiven Non-Hodgkin-Lymphomen (NHL) werden beschrieben. Von Maerz 2001 bis August 2004 wurden 822 PET-CT bei Lymphompatienten zum primaeren Staging, zum Restaging nach Therapie und zur Rezidivdiagnostik an unserer Klinik durchgefuehrt. Fuer die Koregistration wurde ein Low-dose-CT ohne i.v.-Kontrastmittel verwendet. Durch die exakte anatomische Zuordnung der {sup 18}F-FDG aufnehmenden Laesionen wurden unklare oder falsch-positive PET-Befunde vermieden. Die PET-CT erzielte im Vergleich zur KM-verstaerkten CT eine hoehere Sensitivitaet und Spezifitaet bei Patienten mit HD und aggressiven NHL. Die Integration der PET-CT in die Planung der Strahlentherapie fuehrte zu einer Optimierung der Feldgrenzen. Die PET-CT hat sich bereits in der Phase der initialen klinischen Evaluation als wertvoll beim Staging und Restaging von Lymphomen erwiesen.

    Full Text Available Rheumatoid arthritis is the most common autoimmune disease that affects the joints. The cause of the disease is unknown, many studies proposed hypothesis about the etiology of rheumatoid arthritis. The clinical manifestations of arthritis are different in each patients. In addition, the development of the medication is still continue to achieve the most effective role with less side effect. Nanoparticles may be the answer to this problem, since they have been widely used to improve the pharmacokinetic and pharmacodynamics of rheumatoid arthritis drugs. Using nanoparticles-tagged folate or PEG to deliver rheumatoid arthritis drugs may increase the specificity of the drugs to the target and consequently, may decrease the side effects of the drugs. The purpose of this review is to summarize the etiology, clinical manifestation and highlighting the use of nanoparticles in rheumatoid arthritis treatment.

    The study reported covers 28 patients who were examined once by radiology before surgery, and twice after surgery. The first post-surgery examination was done on days 5-7, the second during the 4th until 6th month after surgery. For the first examination, water-soluble contrast agent was initially applied, then barium containing contrast agent. The second examination was done by modified double contrast technique. The most frequent, pre-surgery findings revealed gastro-esophageal reflux in 13 patients. The first post-surgery control detected a somastenosis in 2 patients, while the second control examination detected complications of various nature in 11 patients and gastro-esophageal reflux in 5 patients. In 6 patients, discrepancy between clinical and radiological findings was stated. The pouch size did not correlate with the frequency of complications, or with the body-to-mass index decrease. The examination method proposed in this article yields pre-surgery information on the anatomy of the stomach, more accurate dewscription of post-surgery complications, and better evaluation of the antireflux effect of the vertical gastroplasty.

    2000-01-01

    We report a case of rheumatoid nodule of the right knee in a 55-year-old woman which on the basis of MR images was misdiagnosed as soft tissue sarcoma. Reumatoid nodules occur in up to 20% of adult patients with rheumatoid arthritis and most patients with rheumatoid nodules are rheumatoid factor positive. The nodules are most commonly located between the skin and an underlying bony prominence. In this case, the patient had a history of rheumatoid arthritis and a soft tissue mass was present in the lateral aspect of the right knee. T1-weighted images revealed a mass of similar signal intensity to that of muscle, and on T2-weighted images, a central portion of high signal intensity was noted. Enhanced T1-weighted images demonstrated peripheral rim enhancement. The mass extended to subcutaneous tissue, with penetration of lateral patellar retinaculum. Excisional biopsy was performed, and the pathologic diagnosis was rheumatoid nodule. Although its radiologic findings are non-specific, rheumatoid nodule should -in appropriate clinical setting- be included in the differential diagnosis of a predominantly solid or centrally necrotic periarticular soft tissue.

    Subcutaneous rheumatoid nodules occur commonly in advanced cases of rheumatoid arthritis, but only rarely appear in the feet. We present a case of a subcutaneous rheumatoid nodule arising in the heel pad of a 68-year-old man with a long history of rheumatoid arthritis, along with a review of the literature. The appearance of the mass on MRI is illustrated and correlated with the histologic findings. The MRI appearance of a subcutaneous rheumatoid nodule is that of a nonspecific ill-defined mass with long T1- and long T2-relaxation times. A differential diagnosis for similar appearing masses is offered. (orig.)

    A 30-year-old female patient with coexisting ankylosing spondylitis and rheumatoid arthritis was diagnosed and treated. The human leukocyte antigen (HLA)-B27 is a predisposing factor of ankylosing spondylitis and HLA-DR4 is a predisposing factor of rheumatoid arthritis. This patient was HLA-B27 and HLA-DR4 positive, and ankylosing spondylitis manifested before rheumatoid arthritis. After disease modifying anti-rheumatic drugs successfully arrested ankylosing spondylitis activity the patient conceived and delivered a healthy baby. One year later, she developed peripheral polyarthritis and was diagnosed with rheumatoid arthritis. We hypothesized that pregnancy may be one of the environmental factors that can activate rheumatoid arthritis, and that disease modifying anti-rheumatic drugs play an important role in keeping the disease under control.

    The regional service of the Chinese BeiDou satellite navigation system is now in operation with a constellation including five Geostationary Earth Orbit satellites (GEO), five Inclined Geosynchronous Orbit (IGSO) satellites and four Medium Earth Orbit (MEO) satellites. Besides the standard positioning service with positioning accuracy of about 10 m, both precise relative positioning and precise point positioning are already demonstrated. As is well known, precise orbit and clock determination is essential in enhancing precise positioning services. To improve the satellite orbits of the BeiDou regional system, we concentrate on the impact of the tracking geometry and the involvement of MEOs, and on the effect of integer ambiguity resolution as well. About seven weeks of data collected at the BeiDou Experimental Test Service (BETS) network is employed in this experimental study. Several tracking scenarios are defined, various processing schemata are designed and carried out; and then, the estimates are compared and analyzed in detail. The results show that GEO orbits, especially the along-track component, can be significantly improved by extending the tracking network in China along longitude direction, whereas IGSOs gain more improvement if the tracking network extends in latitude. The involvement of MEOs and ambiguity-fixing also make the orbits better.

    A nonerosive form of rheumatoid arthritis (R.A.) was found in 62 patients out of 660 patients with R.A.. These 62 patients exhibit slowly progressive cystic changes in about the same joints in which usually erosions develop in classic R.A.. The E.S.R. is often low, half of the patients remained seronegative and there are 35 males and 27 females in the group. A smaller group of 15 out of these patients could be followed from a stage wherein the radiographs were normal to a stage of extensive cystic changes, over a period of at least 6 years. An attempt is made to delineate this group within the rheumatoid arthritis disease entity.

    Purpose: To report feasibility, benefit and complications of penile angiography and superselective penile embolization in arterial priapism. Materials and Methods: Four consecutive patients (aged 28, 29, 40 and 49 years), who underwent penile angiography for arterial priapism (high-flow priapism) within a four-year period, were identified by a keyword search of our radiology information system. One patient had sustained a direct penile trauma (severe blow to the erected penis) and three patients suffered from recurrent spontaneous priapism. All patients had previously undergone corporeal aspiration and noradrenaline injection to achieve detumescence. Two patients had one or several unsuccessful spongiocavernous shunt procedures. Results: In three of the four patients, superselective pudendal and penile angiography demonstrated pathologic arteriocavernous shunting. In two of the three patients, superselective embolization using a coaxial micro-catheter was attempted. In one of the two patients, the cavernous artery became spastic before embolization material was actually injected, inducing immediate and lasting detumescence. In the other patient, unilateral Gelfoam embolization led to immediate detumescence but the priapism recurred 12 hours after the procedure. A subsequent contralateral Gelfoam embolization was successful. Erectile function was preserved in all cases. No procedure-related complications occurred. Conclusion: Our experience supports the prevailing opinion found in the current literature that superselective coaxial embolization constitutes the treatment of choice in patients with high-flow priapism. Prognosis is good with high probability of preserving the erectile function. (orig.)

    Purpose. To assess the accuracy of different MR sequences for the detection of articular cartilage abnormalities in rheumatoid arthritis. Design and patients. Ten metacarpophalangeal joints and 10 metatarsophalangeal joints (specimens from arthritis patients undergoing ablative joint surgery) were examined with a fat-suppressed (FS) 3D FLASH, a FS 3D FISP, a FS 2D fast spin-echo T2-weighted, and a 2D FS spin-echo T1-weighted sequence. Each cartilage lesion and each cortical lesion was graded from 0 to 4 (modified Outerbridge staging system). Subsequently, the results of each sequence were compared with the macroscopic findings and statistically tested against each other. Results. The study shows that 3D gradient-echo sequences with fat suppression were best for imaging and grading of cartilage lesions in arthritis of the small joints of the hands and feet. Using 3D techniques, all grade 2, grade 3, and grade 4 lesions of cartilage or cortical bone were detected. Conclusion. FS 3D gradient-echo techniques were best for the detection and grading of hyaline cartilage and subchondral bone lesions in rheumatoid arthritis. MRI has a great potential as an objective method of evaluating cartilage damage and bone erosions in rheumatoid arthritis. (orig.)

    group data without the need for voxel-based congruence. (orig.) [German] fMRT-Untersuchungen sind durch den geringen aktivierungsinduzierten Signalunterschied in ihrer Sensitivitaet limitiert und innerhalb kurzer tolerierbarer Messzeiten ist die raeumliche Aufloesung limitiert. fMRT bei 1,5 und mehr noch bei 3 T ist ein zuverlaessiges Werkzeug in der Neurowissenschaft und fuer klinische Anwendungen, wie etwa die praechirurgische Funktionslokalisierung. Die fMRT-Sensitivitaet steigt stark (mehr als linear) mit hoeherer Magnetfeldstaerke. Dies war seit Jahren einer der Hauptgruende fuer die Entwicklung zu hoeheren Feldern wie etwa 7 T. Der Sensitivitaetsgewinn von 7 gegenueber 3 T ist bei hoher raeumlicher Aufloesung am groessten und die fMRT mit sehr hoher isotroper Submillimeteraufloesung wird moeglich. Bisherige Resultate zeigen, dass die Blood-oxygenation-level-dependent(BOLD)-Lokalisierung deutlich praeziser ist als bislang angenommen. Mittels Hochfeld-fMRT werden nicht nur quantitativ bessere Ergebnisse erzielt, sondern Informationen neuer Qualitaet zugaenglich wie etwa die kolumnare und schichtabhaengige Struktur des Kortex. Somit wird der Weg zu weiteren Informationen, wie etwa die Richtung kortikaler Verbindungen, eroeffnet. Diese Moeglichkeiten bergen jedoch auch neue Herausforderungen. So muessen neue Verfahren zur Prozessierung derart hochaufgeloester Daten entwickelt werden, welche z. B. ohne Glaettung auskommen, um den Informationsgehalt der Daten nicht zu reduzieren. Standardaufloesungen von 2-3 mm sind weiterhin bei 3 T ''gut aufgehoben'' und profitieren von geringeren Signalausloeschungen, weniger Verzerrungen und geringerer Lautstaerke. Zum Erreichen hoechster Aufloesung bei 7 T sind parallele Bildgebung und Verzerrungskorrektur essenziell und ermoeglichen eine gute Uebereinstimmung mit anatomischen Aufnahmen. Die Echozeit sollte bei 7 T auf ca. 20-25 ms angepasst und die Datenauswertung fuer einzelne Probanden oder Patienten ohne

    The hands and wrists of 20 top-level rock climbers with sports injuries and overstress abnormalities were compared with the hands and wrists of 10 normal volunteers. They were all studied with MR imaging at 1.5 T. The imaging protocol included spin-echo and gradient-echo sequences with 1- to 5-mm-thick contiguous slices in the axial, coronal and/or sagittal planes, depending on the location and nature of the suspected injury. Typical hand and wrist lesions depicted with MRI in climbers consisted of annular ligament tears, lesions of the flexor tendons, tenosynovitis, ganglion cysts, joint effusion and functional carpal tunnel syndrome. The MRI findings on these abnormalities were compared to normal findings and those with ultrasound and plain films. In addition, hypertrophic changes in the muscles, tendons, ligaments, and bones of top-level rock climbers were assessed morphometrically. MRI proved to be the superior imaging modality in the diagnosis of sports injuries and overstress abnormalities of the hand the wrist in rock-climbing athletes. (orig.).

    Full Text Available Juvenile rheumatoid arthritis (JRA is the most common rheumatic condition in children. JRA is defined as persistent arthritis in 1 or more joints for at least 6 weeks, with the onset before age 16 years. The etiology of JRA is unknown. Antigen activated CD4+ T cell stimulate monocytes, macrophages, and synovial fibroblasts to produce the cytokines Interleukin-1 (IL-1, IL-6, and tumor necrosis factor ? (TNF-? and to secrete matrix metalloproteinases, which lead to chronic inflammation due to infiltration of inflammatory cell, angiogenesis, destruction of cartilage and bone with pannus formation. The 3 major subtypes of JRA are based on the symptoms at disease onset and are designated systemic onset, pauciarticular onset, and polyarticular onset. For all patients, the goals of therapy are to decrease chronic joint pain and suppress the inflammatory process. Poor prognostic have been observed in patients with polyarticular onset, rheumatoid factor, persistent morning stiffness, tenosynovitis, involvement of the small joints, rapid appearance of erosions, active late onset childhood, subcutaneous nodules, or antinuclear antibody.

    Rheumatoid arthritis (RA) is the most common inflammatory rheumatic disease, affecting almost 1% of the world population. Although the cause of RA remains unknown, the complex interaction between immune mediators (cytokines and effector cells) is responsible for the joint damage that begins at the synovial membrane. Activated macrophages are critical in the pathogenesis of RA and showed specifically express a receptor for the vitamin folic acid (FA), folate receptor β (FRβ). This particular receptor allows internalization of FA-coupled cargo. In this review we will address the potential of nanoparticles as an effective drug delivery system for therapies that will directly target activated macrophages. Special attention will be given to stealth degree of the nanoparticles as a strategy to avoid clearance by macrophages of the mononuclear phagocytic system (MPS). This review summarizes the application of FA-target nanoparticles as drug delivery systems for RA and proposes prospective future directions. Rheumatoid arthritis is a debilitating autoimmune disease of the joints which affects many people worldwide. Up till now, there is a lack of optimal therapy against this disease. In this review article, the authors outlined in depth the current mechanism of disease for rheumatoid arthritis and described the latest research in using folic acid-targeted nanoparticles to target synovial macrophages in the fight against rheumatoid arthritis.

    Rheumatoid patients may develop a retrodental lesion (atlantoaxial rheumatoid pannus) that may cause cervical instability and/or neurological compromise. The objective is to characterize clinical and radiographic outcomes after posterior instrumented fusion for atlantoaxial rheumatoid pannus. We retrospectively reviewed all patients who underwent posterior fusions for an atlantoaxial rheumatoid pannus at a single institution. Both preoperative and postoperative imaging was available for all patients. Anterior or circumferential operations, non-atlantoaxial panni, or prior C1-C2 operations were excluded. Primary outcome measures included Nurick score, Ranawat score (neurologic status in patients with rheumatoid arthritis), pannus regression, and reoperation. Pannus volume was determined with axial and sagittal views on both preoperative and postoperative radiological images. Thirty patients surgically managed for an atlantoaxial rheumatoid pannus were followed for a mean of 24.43 months. Nine patients underwent posterior instrumented fusion alone, while 21 patients underwent posterior decompression and instrumented fusion. Following a posterior instrumented fusion in all 30 patients, the pannus statistically significantly regressed by 44.44%, from a mean volume of 1.26cm(3) to 0.70cm(3) (ppannus radiographically regressed by 44.44% over a mean of 8.02 months, and patients clinically improved per the Nurick score. The Ranawat score did not improve, and 20% of patients required reoperation over a mean of 13.18 months. The annualized reoperation rate was approximately 13.62%. Copyright © 2015 Elsevier B.V.

    Schwere Verlaufsformen der Alopecia areata (AA) im Kindesalter sind aufgrund limitierter Optionen therapeutisch herausfordernd. Systemische, hochdosierte Glukokortikoide weisen die schnellste Ansprechrate auf, nach dem Absetzen kommt es allerdings zu Rezidiven. Eine längerfristige Hochdosis-Anwendung ist aufgrund der zu erwartenden Nebenwirkungen nicht empfehlenswert. Eine dauerhafte Steroiderhaltungstherapie unterhalb der Cushing-Schwellen-Dosis nach Bolustherapie könnte die Krankheitsaktivität ohne Nebenwirkungen längerfristig unterdrücken. Im Rahmen einer offenen Anwendungsbeobachtung wurden 13 Kinder mit schweren Formen der AA in diese Studie eingeschlossen. Bei sieben Kindern lag eine AA totalis/universalis vor, bei sechs eine multifokale AA mit Befall von mehr als 50 % der Kopfhaut. Das Therapieregime sah eine initiale Prednisolon-Dosierung von 2 mg/kg Körpergeweicht (KG) vor und wurde innerhalb von neun Wochen auf eine Erhaltungsdosierung unter der individuellen Cushing-Schwelle reduziert. Der Nachbeobachtungszeitraum betrug ein bis drei Jahre. Wir beobachteten in 62 % aller Fälle ein komplettes Nachwachsen der Haare. Die mittlere Dauer bis zum Ansprechen lag bei 6,6 Wochen und konnte mit der Erhaltungstherapie über den gesamten Beobachtungszeitraum aufrechterhalten werden. An Nebenwirkungen wurden ausschließlich eine Gewichtszunahme (1-3 kg) bei allen Behandelten sowie eine milde Steroidakne in 23 % der Fälle beobachtet. Die kombinierte Hoch-/Niedrig-Dosis-Therapie mit systemischen Glukokortikoiden mittels Prednisolon zeigte eine hohe, dauerhafte Ansprechrate ohne signifikante Nebenwirkungen. © 2017 Deutsche Dermatologische Gesellschaft (DDG).

    Full Text Available Pamidronate is a bisphosphonate derivative that can inhibit bone resorption by actions on osteoclasts and increase bone density in spite of treatment with steroids. This drug has the anti-inflammatory effect by increase apoptosis of monocytes. 5-10 percent of rheumatoid arthritis patients is seronegative and may be resistant to conventional disease modifying anti rheumatic drugs (DMARDs. Intravenous (IV pamidronate can be effective in disease control in seronegative rheumatoid arthritis. We report two cases of seronegative and drug resistant rheumatoid arthritis that favorably responds to pamidronate.

    Rheumatoid arthritis patients are at higher risk of developing comorbidities. The main objective of this study was to evaluate the prevalence of major comorbidities in Chinese rheumatoid arthritis patients. We also aimed to identify factors associated with these comorbidities. Baseline demographic, clinical characteristics and comorbidity data from RA patients enrolled in the Chinese Registry of rhEumatoiD arthrITis (CREDIT) from Nov 2016 to August 2017 were presented and compared with those from five other registries across the world. Possible factors related to three major comorbidities (cardiovascular disease, fragility fracture and malignancy) were identified using multivariate logistic regression analyses. A total of 13,210 RA patients were included (80.6% female, mean age 52.9 years and median RA duration 4.0 years). Baseline prevalence rates of major comorbidities were calculated: CVD, 2.2% (95% CI 2.0-2.5%); fragility fracture, 1.7% (95% CI 1.5-1.9%); malignancy, 0.6% (95% CI 0.5-0.7%); overall major comorbidities, 4.2% (95% CI 3.9-4.6%). Advanced age was associated with all comorbidities. Male gender and disease duration were positively related to CVD. Female sex and longer disease duration were potential risk factors for fragility fractures. Ever use of methotrexate (MTX) was negatively related to baseline comorbidities. Patients with rheumatoid arthritis in China have similar prevalence of comorbidities with other Asian countries. Advanced age and long disease duration are possible risk factors for comorbidities. On the contrary, MTX may protect RA patients from several major comorbidities, supporting its central role in the management of rheumatoid arthritis.

    The authors propose an original method of X-ray examination of hands and feet which makes possible simultaneous radiography without screen and direct twofold magnified film taking. The method is not connected with the necessity of exposing the patient to an additional dose of X-rays. It has been tried in 20 patients with suspected rheumatoid arthritis. It requires an X-ray tube with 0.3 x 0.3 mm microfocus. (author)

    A detail examination of the hands and feet was performed in a group of 34 patients affected by systemic lupus erythematosus (SLE), using low-dose mammographic film and Rank Xerox selenium plate, according to current diagnostic techniques. All patients presented articular symptoms (pain and arthralgia). The high incidence (38.8%) of patients with no radiographic evidence of bone damage-even though articular symptoms are present-is emphasized. In such cases, it is very difficult to distinguish SLE from rheumatoid arthritis, especially as far as therapeutic management and prognosis are concerned. The lack of any pathognomonic radiological sign of the lupus arthritis, in the hands as well as in the feet, is then stressed. Nevertheless, artropathy in SLE is defined as a deforming unerosive arthritis, with a typical symmetric distribution, affecting most commonly (according to incidence) the proximal interphalangeal and metacarpophalangeal joints. In the hand, arthropathy is referred to as Jaccoud's type arthritis, because it is characterized by joint deformities which can be corrected. In the foot, the main abnormalities include hallux valgus, subluxation of the matatarsophalangeal joints and widening of the forefoot

    Thermotherapy is often used as adjunct in the treatment of rheumatoid arthritis (RA) by rehabilitation specialists. To evaluate the effectiveness of different thermotherapy applications on objective and subjective measures of disease activity in patients with RA. We searched Medline, EMBASE, Pedro, Current Contents, Sports Discus and CINAHL up to and including September 2001. The Cochrane Field of Rehabilitation and related therapies and the Cochrane Musculoskeletal Review Group were also contacted for a search of their specialized registers. Hand searching was conducted on all retrieved articles for additional articles. Comparative controlled studies, such as randomized controlled trials, controlled clinical trials, cohort studies or case/control studies, of thermotherapy compared to control or active interventions in patients with RA were eligible. No language restrictions were applied. Abstracts were accepted. Two independent reviewers identified potential articles from the literature search (VR, LB). These reviewers extracted data using pre-defined extraction forms. Consensus was reached on all data extraction. Quality was assessed by two reviewers using a 5 point scale that measured the quality of randomization, double-blinding and description of withdrawals. Seven studies (n=328 subjects) met the inclusion criteria. The results of this systematic review of thermotherapy for RA found that there was no significant effect of hot and ice packs applications (Ivey 1994), cryotherapy (Rembe 1970) and faradic baths (Hawkes 1986) on objective measures of disease activity including joint swelling, pain, medication intake, range of motion (ROM), grip strength, hand function compared to a control (no treatment) or active therapy. There is no significant difference between wax and therapeutic ultrasound as well as between wax and faradic bath combined to ultrasound for all the outcomes measured after 1, 2 or 3 week(s) of treatment (Hawkes 1986).

    Minimally invasive treatment of spinal fractures. Conservative treatment versus spinal surgery. Minimally invasive stabilization techniques, such as percutaneous (assisted) cementoplasty have been introduced as new procedures. Magnetic resonance imaging (MRI), X-rays and computed tomography (CT) are the imaging techniques of first choice. The most important questions concern recent fractures, instability and indications for minimally invasive treatment. Vertebroplasty and kyphoplasty are established methods for the treatment of patients with osteoporosis. Cementoplasty techniques are promising treatment options for traumatic spinal injuries.

    Full Text Available Objective: Rheumatoid arthritis (RA differs depending on the age of disease onset. The differences between EORA and YORA are important because they have clinical and therapeutic implications. Method: 1185 patients were ranked after classification according to age at onset of the disease into YORA I (16–40 years, YORA II (41–60 years and EORA .60 years. All patients groups were compared, based on disease duration, disease activity, severity parameters and drug history. Results: YORA I included 298 patients, 28.85% were males, with mean age of 29.4 ± 6 years and disease duration 4 ± 3.3 y, YORA II included 539 patients, 33.77% males, age 49.7 ± 6.1 y and disease duration 6.5 ± 5.6 y. EORA included 348 RA patients 40.5% males, age 67.1 ± 6.6 y, disease duration 9.95 ± 7.2 y. Activity was increased in EORA compared to YORA I and YORA II, while severity decreased in EORA. ESR, CRP and degree of anemia were higher in EORA. RF titer was higher in YORA. Small joints of the hands and feet were more involved in YORA, while, large joints in EORA. Rheumatoid nodules were increased in YORA I than EORA P = 0.04. Polymyalgia rheumatica was exclusively present in EORA group 25 patients 7.2%. Methotrexate was used in both YORA and EORA, with a higher mean of dosage in YORA than EORA. Multiple DMARDs in EORA was 57.9%, and biologics in 0.8% was which was significantly lower compared with YORA I, 86.3% and 1.7%, with P = 0.001. Conclusion: EORA has more active and less disabling and affects more males than YORA. The use of biologic therapy and combination DMARD therapy was less in EORA.

    To investigate the autonomic nervus system involvement in cases with rheumatoid arthritis (RA) by assesing sympathetic skin response (SSR) and R-R interval variation (RRIV), 14 healthy women and 10 women with RA, all of them without clinic dysautonomies were examined. SSR's were recorded palmar surface of both hands and soles of both feet, after stimulating median and tibial nerves individually. RRIV's were assessed at rest and during six deep breathing in one minute with electrodes placed on dorsal surfaces of both hands. SSR could not be obtained from lower extremities of one case with RA. We could not find any significant difference between two groups in terms of SSR latencies. RRIV values obtained during deep breathing to those recorded at rest (D%/R%) was found to be significantly lower in RA cases than healthy controls. RRIV values increased with deep breathing in healthy subjects, while they decreased in 50% of the RA cases. We conclude that assessment of SSR and RRIV are valuble methods for revelation of subclinical autonomic involvement in cases with RA.

    Cryotherapy, whether administered through ice, cold air, nitrogen, or cold packs has an analgetic effect that can even reach the point of pain elimination. It also inhibits inflammation, relieves swelling, and improves the function of inflamed joints. Further effects are alleviation of excess muscle tone and maintenance of blood irrigation in inflamed tissue. The fields of indication for cryotherapy can be summarised as follows: inflammation, pain, swelling, functional inhibition, excess muscle tone.

    The 99m Tc hydroxy methylene diphosphonate scintigraphic findings of both hands are correlated to the radiographic findings in a patient with a 30-year history of gouty arthropathy. Scintigraphic differentiation of the type of arthritis on the basis of uptake pattern is difficult. However, the findings of rheumatoid arthritis are confined to the joints and usually the involvement is symmetrical. With gout there is a tendency toward asymmetrical, bilateral, multifocal joint involvement with areas of intense abnormal uptake; because of the associated soft tissue swelling, the intense uptake usually extends beyond the involved joints.

    Rice body formation is a nonspecific response to chronic synovial inflammation associated with tuberculous arthritis, rheumatoid arthritis, juvenile rheumatoid arthritis, seronegative inflammatory arthritis, and even osteoarthritis. Such bodies were termed rice bodies because of their close resemblance to grains of polished white rice. We present a case report of a middle-aged woman with right shoulder subacromial/subdeltoid bursitis with giant rice body formation as her initial presentation of rheumatoid arthritis. Her right shoulder symptoms resolved after subacromial and subdeltoid bursectomy and removal of the rice bodies. She subsequently developed inflammatory arthritis of other joints, met the criteria for rheumatoid arthritis, and has been treated medically.

    A new radioimmunoassay has been developed for measuring IgM and IgG rheumatoid factors. Diluted sera from donors and patients were incubated with immunoprecipitates prepared from sheep serum and rabbit anti-sheep IgG antiserum. The precipitates were washed, and radioiodinated rabbit F(ab')/sub 2/ fragments specific for human IgM or IgG were added. The precipitates were isolated by filtration and measured in a gamma counter. With this assay IgM rheumatoid factors were detected in sera from all patients with seropositive rheumatoid arthritis and in sera from 40% of patients with seronegative rheumatoid arthritis. IgG rheumatoid factors were found in sera from 68% of the seropositive and 40% of the seronegative patients. Gel filtration experiments demonstrated that it is possible to detect monomeric IgG rheumatoid factors and IgM rheumatoid factors of molecular weight smaller than pentameric IgM. Furthermore it has been shown that IgG rheumatoid factor activity is still present after reduction of IgM rheumatoid factors with dithiotreitol.

    Mruck, S.; Feistel, H.; Kat, S.; Kuwert, T.

    2001-01-01

    Radiosynovectomy is a therapeutic modality for local treatment of inflammatory point diseases. It is performed by intraarticular instillation of beta-emitting radionuclides. Its effectiveness is based upon the anti-inflammatory action of beta-radiation. Accordingly, the indication of radiosynovectomy is based upon the evidence of the inflammatory etiology of disease. The principle of its therapeutic action makes radiosynovectomy a valuable device for successful treatment of florid rheumatoid arthritis. It can be performed as an alternative to surgical synovectomy or in combination with it. The following article describes the therapeutic management of rheumatoid arthritis by radiosynovectomy including patient preparation, performance, and follow-up. (orig.) [de

    BACKGROUND Rheumatoid arthritis is a chronic inflammatory disease with a substantial genetic component. Susceptibility to disease has been linked with a region on chromosome 2q. METHODS We tested single-nucleotide polymorphisms (SNPs) in and around 13 candidate genes within the previously linked chromosome 2q region for association with rheumatoid arthritis. We then performed fine mapping of the STAT1-STAT4 region in a total of 1620 case patients with established rheumatoid arthritis and 2635 controls, all from North America. Implicated SNPs were further tested in an independent case-control series of 1529 patients with early rheumatoid arthritis and 881 controls, all from Sweden, and in a total of 1039 case patients and 1248 controls from three series of patients with systemic lupus erythematosus. RESULTS A SNP haplotype in the third intron of STAT4 was associated with susceptibility to both rheumatoid arthritis and systemic lupus erythematosus. The minor alleles of the haplotype-defining SNPs were present in 27% of chromosomes of patients with established rheumatoid arthritis, as compared with 22% of those of controls (for the SNP rs7574865, P = 2.81×10-7; odds ratio for having the risk allele in chromosomes of patients vs. those of controls, 1.32). The association was replicated in Swedish patients with recent-onset rheumatoid arthritis (P = 0.02) and matched controls. The haplotype marked by rs7574865 was strongly associated with lupus, being present on 31% of chromosomes of case patients and 22% of those of controls (P = 1.87×10-9; odds ratio for having the risk allele in chromosomes of patients vs. those of controls, 1.55). Homozygosity of the risk allele, as compared with absence of the allele, was associated with a more than doubled risk for lupus and a 60% increased risk for rheumatoid arthritis. CONCLUSIONS A haplotype of STAT4 is associated with increased risk for both rheumatoid arthritis and systemic lupus erythematosus, suggesting a shared pathway

    Rheumatoid arthritis is an inflammatory synovial disease thought to involve T cells reacting to an antigen within the joint. Type II collagen is the major protein in articular cartilage and is a potential autoantigen in this disease. Oral tolerization to autoantigens suppresses animal models of T cell-mediated autoimmune disease, including two models of rheumatoid arthritis. In this randomized, double-blind trial involving 60 patients with severe, active rheumatoid arthritis, a decrease in the number of swollen joints and tender joints occurred in subjects fed chicken type II collagen for 3 months but not in those that received a placebo. Four patients in the collagen group had complete remission of the disease. No side effects were evident. These data demonstrate clinical efficacy of an oral tolerization approach for rheumatoid arthritis.

    Diagnostic opportunities of scintigraphy with sup(113m)In- eluate in 49 rheumatoid arthritis patients with prevalent knee joint affections at the exudative-proliferative period of the disease have been studied. Selective accumulation of radionuclide in the inflammatory tissue forms the basis of the method. It is shown that the scintigraphic study (scintiscanning) with sup(113m)In allows to differentiate between the exudative ad exudative-proliferative stages of rheumatoid arthritis and to assess the results of medicamentary treatment

    2009-01-01

    The introduction of disease-modifying antirheumatic drugs has created new demands on imaging to early identify patients with rheumatoid arthritis and opened new prospects in therapeutic management of patients with aggressive disease. Therefore, new imaging modalities such as magnetic resonance imaging and ultrasound have developed during the past few years in this field. In some cases, both magnetic resonance imaging and ultrasound may be also useful in making the distinction between early rheumatoid arthritis and other joints abnormalities, including early psoriatic arthritis. This article will review key aspects of important advances in imaging in rheumatoid arthritis, particularly focusing on magnetic resonance imaging and ultrasound.

    2011-09-01

    Full Text Available Pannus formation is a fundamental event in the pathogenesis of rheumatoid arthritis and its hypervascularisation seems to be crucial to the development of joint damage. High-resolution greyscale ultrasonography is a safe, quick, and inexpensive imaging tool that allows an accurate detection of even minimal morphostructural changes in patients with rheumatoid arthritis, including joint effusion, thickening of synovial membrane and bone erosions. More recently, power Doppler sonography has proved to be a reliable tool for semiquantitative assessment of the vascularity of the synovial tissue. The contrast-enhanced power Doppler sonography seems to be a helpful adjunct in assessing synovitis and the therapeutic response to the different therapies in patients with rheumatoid arthritis. The aim of this radiological vignette was to show a representative example of use of power Doppler sonography with contrast agent in assessing rheumatoid synovitis.

    A nonerosive form of rheumatoid arthritis (R.A.) was found in 62 patients out of 660 patients with R.A.. These 62 patients exhibit slowly progressive cystic changes in about the same joints in which usually erosions develop in classic R.A.. The E.S.R. is often low, half of the patients remained seronegative and there are 35 males and 27 females in the group. A smaller group of 15 out of these patients could be followed from a stage wherein the radiographs were normal to a stage of extensive cystic changes, over a period of at least 6 years. An attempt is made to delineate this group within the rheumatoid arthritis disease entity. (orig.) [de

    In this study we aimed to describe the magnetic resonance imaging (MRI) pattern of the distribution of bone marrow edema (BME) and joint erosion in hands and wrists of patients with systemic lupus erythematosus (SLE) with arthritis in comparison with rheumatoid arthritis (RA) and healthy subjects (H). SLE patients with arthritis (n = 50), patients with RA (n = 22), and H (n = 48) were enrolled. Every patient underwent a non-dominant hand (2nd-5th metacarpophalangeal joints) and wrist MRI without contrast injection with a low-field extremity dedicated 0.2-Tesla instrument. BME was observed in two SLE patients in the hand (4 %) and in 15 in the wrist (13 %) versus three (30 %), and 14 (63 %) RA patients. No BME was found in H. Erosions were observed in the hand in 24 SLE patients (48 %), 15 RA patients (68 %), and 9 H (18 %); in the wrist, in 41 (82 %) SLE, all RA and 47 (97 %) H. The cumulative erosive burden in SLE was significantly higher than in H (c = 0.002) but similar to RA patients. Joint involvement of the wrist in SLE is similar to RA and is not as rare as expected, as shown by the comparison with healthy subjects. On the contrary, the involvement of the hand in SLE is significantly lower compared to RA. (orig.)

    Central nervous system (CNS) involvement by rheumatoid arthritis (RA) in the form of rheumatoid meningitis (RM) is rare and most commonly occurs in the setting of longstanding severe RA. Due to a wide range of clinical presentations and nonspecific laboratory findings, it presents a diagnostic challenge often requiring brain biopsy. Only a few histopathologically confirmed cases have been described in the literature. Our aim is to describe two cases of RM and review the literature. The first case is of a previously healthy 37-year-old man who presented with severe headaches and focal neurologic deficits. Magnetic resonance imaging demonstrated abnormal leptomeningeal enhancement in the left frontal and parietal sulci. The second case is of a 62-year-old woman with a history of mild chronic joint pain who presented with confusion, personality changes and seizures. Both patients ultimately underwent brain biopsy which demonstrated RM on pathologic examination. Administration of corticosteroids resulted in significant clinical improvement in both cases. To our knowledge, our unusual case of RM in the young man is the fifth reported case of rheumatoid meningitis in a patient with no prior history of RA. Such an atypical presentation makes diagnosis even more difficult and highlights the need for awareness of this entity in the diagnostic consideration of a patient presenting with unexplained neurologic symptoms. Our literature review underscores the clinical and pathologic heterogeneity of CNS involvement in RA. © 2015 Japanese Society of Neuropathology.

    Due to a significant overlap of the two syndromes, differentiation of degenerative dementia of the Alzheimer-type from vascular dementia may be difficult even when imaging studies are available. White matter changes occur in many patients suffering from Alzheimer's disease. Little is known about the impact of white matter changes on the course and clinical presentation of Alzheimer's disease. High sensitivity of MRI in the detection of white matter alterations may account for over-diagnosing vascular dementia. The clinical significance of white matter alterations in dementia is still a matter of debate. The article reviews current concepts about the role of white matter alterations in dementia. (orig.) [German] Die Zuordnung einer Demenzerkrankung zu einem neurodegenerativen Pathomechanismus, wie der Demenz vom Alzheimer-Typ (DAT) oder einem vaskulaeren Pathomechanismus, kann trotz der Verfuegbarkeit bildgebender Verfahren Probleme bereiten.

Mikroangiopathische Veraenderungen des Marklagers finden sich bei einem hohen Anteil von Patienten mit der klinischen Verlaufsform einer Demenz vom Alzheimer-Typ. Es ist unklar, ob es sich um eine Koinzidenz zweier Pathomechanismen handelt oder ob eine wechselseitige Beeinflussung stattfindet.

    Full Text Available Abstract Rheumatoid arthritis (RA is an inflammatory, polyarticular joint disease. A number of cellular responses are involved in the pathogenesis of rheumatoid arthritis, including activation of inflammatory cells and cytokine expression. The cellular responses involved in each of these processes depends on the specific signaling pathways that are activated; many of which include protein tyrosine kinases. These pathways include the mitogen-activated protein kinase pathway, Janus kinases/signal transducers and activators transcription pathway, spleen tyrosine kinase signaling, and the nuclear factor κ-light-chain-enhancer of activated B cells pathway. Many drugs are in development to target tyrosine kinases for the treatment of RA. Based on the number of recently published studies, this manuscript reviews the role of tyrosine kinases in the pathogenesis of RA and the potential role of kinase inhibitors as new therapeutic strategies of RA.

    Full Text Available Der Begriff der sensomotorischen diabetischen Neuropathie beschreibt einen heterogenen Beschwerdekomplex, der auf einer diabetesbedingten Schädigung des peripheren Nervensystems beruht. Bis zu 50 % der Menschen mit Diabetes mellitus leiden im Verlauf ihrer Erkrankung an Symptomen einer sensomotorischen Neuropathie. Chronische Schmerzen, Dysund Parästhesien sowie die Komplikation des diabetischen Fußsyndroms stellen für die Betroffenen gravierende Folgen dar. Die Optimierung der metabolischen Kontrolle stellt eine wichtige Basismaßnahme dar. Andere, zweifelsfrei gesicherte Möglichkeiten der Prävention oder kausalen Therapie sind nicht bekannt. Bei Auftreten einer schmerzhaften Neuropathie sollte eine gezielte analgetische Therapie möglichst früh begonnen werden. Mit den trizyklischen Antidepressiva, Duloxetin, Gabapentin und Pregabalin stehen Wirkstoffe zur Verfügung, die eine spezifische Therapie neuropathischer Schmerzen ermöglichen. Dabei ist zu beachten, dass in der Regel keine Schmerzfreiheit erreicht werden kann. Entscheidend ist das Erreichen eines für den Patienten tolerablen Schmerzniveaus unter Minimierung medikamentenassoziierter Nebenwirkungen. Das individuelle Ansprechen auf ein Medikament und die optimale Dosis können nicht vorhergesagt, sondern müssen individuell erprobt werden. Bei leichten Schmerzen können die Nicht-Opioid- Analgetika Paracetamol und Metamizol eingesetzt werden. Fehlen Therapiealternativen, dann stellen Opioide eine weitere Möglichkeit der Therapie starker Schmerzen dar. Aufgrund einer zusätzlichen Monoamin-Wiederaufnahmehemmerwirkung nehmen Tramadol und Tapentadol in dieser Gruppe eine Sonderstellung ein. In der Risiko- Nutzen-Abwägung darf das Nebenwirkungs- und Abhängigkeitspotenzial der Opioide in der Langzeittherapie nicht unterschätzt werden. Für andere medikamentöse Therapien oder alternative Therapiemethoden liegt keine ausreichende wissenschaftliche Evidenz vor. Sie können aber im

    difficult to distinguish between chronic pancreatitis and pancreatic carcinoma. In such cases a PET scan may be helpful. For planning of surgery and for preoperative staging morphological imaging is essential, but in nearly 40% of the patients nonresectable tumors were detected intraoperatively, which were not diagnosed by preoperative CT or MRI. PET seems to be more accurate in this respect, too. (orig.) [Deutsch] Hauptaufgaben der radiologischen und nuklearmedizinischen Diagnostik bei gastrointestinalen Tumoren sind Diagnosesicherung sowie praeoperatives Staging. Die Hohlorgane des oberen und unteren GI-Traktes (Oesophagus, Magen, Duodenum, Kolon, Rektum) werden primaer endoskopisch und endosonographisch abgeklaert. CT oder MRT liefern Informationen ueber Ausdehnung des Tumors, eine Infiltration in umgebende Strukturen und das Vorliegen pathologischer Lymphknoten. Das sensitivste Verfahren zum Nachweis von Lymphknoten- oder Fernmetastasen ist die PET. Auch die Differenzierung eines Lokalrezidivs von postoperativer Narbenbildung, z.B. beim kolorektalen Karzinom, gelingt mit der PET fruehzeitiger als mit den konventionellen morphologischen Verfahren. Lebertumoren sollten primaer sonographisch und bei fraglicher Dignitaet anschliessend mittels MRT untersucht werden. In der Differentialdiagnostik von unklaren Leberherden ist die nuklearmedizinische Rezeptorszintigraphie wegweisend. Benigne Leberlaesionen koennen mit der Neogalaktoalbumin-(NGA-)Szintigraphie sicher von malignen Tumoren (Metastasen, hepatozellulaeres Karzinom [HCC]) abgegrenzt werden, da NGA-Rezeptoren nur auf funktionstuechtigen Hepatozyten experimentiert werden. Die Unterscheidung von Lebermetastasen und dem HCC gelingt mit der Insulinszintigraphie, da sich Insulin aufgrund einer Ueberexpression von Insulinrezeptoren mit HCC vermehrt anreichert. Ergeben die vorgeschalteten Untersuchungen den Verdacht auf einen malignen Prozess, sollte zusaetzlich eine CT-Arterioportographie durchgefuehrt werden, da dieses

    Foot pain is common in rheumatoid arthritis and appears to persist despite modern day medical management. Several clinical practice guidelines currently recommend the use of foot orthoses for the treatment of foot pain in people with rheumatoid arthritis. However, an evidence gap currently exists concerning the comparative clinical- and cost-effectiveness of prefabricated and customised foot orthoses in people with early rheumatoid arthritis. Early intervention with orthotics may offer the best opportunity for positive therapeutic outcomes. The primary aim of this study is to evaluate the comparative clinical- and cost-effectiveness of prefabricated versus customised orthoses for reducing foot pain over 12 months. This is a multi-centre two-arm parallel randomised controlled trial comparing prefabricated versus customised orthoses in participants with early rheumatoid arthritis (rheumatoid arthritis, global functional status via the Stanford Health Assessment Questionnaire, foot disease activity via the Rheumatoid Arthritis Foot Disease Activity Index, and health-related quality of life at baseline, 6 and 12 months. Process outcomes will include recruitment/retention rates, data completion rates, intervention adherence rates, and participant intervention and trial participation satisfaction. Cost-utility and cost-effectiveness analyses will be undertaken. Outcome measures collected at baseline, 6 and 12 months will be used to evaluate the comparative clinical- and cost- effectiveness of customised versus prefabricated orthoses for this treatment of early rheumatoid arthritis foot conditions. This trial will help to guide orthotic prescription recommendations for the management of foot pain for people with early rheumatoid arthritis in future. ISRCTN13654421. Registered 09 February 2016.

    Background Rehabilitation approaches for people with rheumatoid arthritis include joint protection, exercises and self-management strategies. Health interventions delivered via the web have the potential to improve access to health services overcoming time constraints, physical limitations, and socioeconomic and geographic barriers. The objective of this review is to determine the effects of web-based rehabilitation interventions in adults with rheumatoid arthritis. Methods Randomised controlled trials that compared web-based rehabilitation interventions with usual care, waiting list, no treatment or another web-based intervention in adults with rheumatoid arthritis were included. The outcomes were pain, function, quality of life, self-efficacy, rheumatoid arthritis knowledge, physical activity and adverse effects. Methodological quality was assessed using the Cochrane Risk of Bias tool and quality of evidence with the Grading of Recommendations Assessment, Development and Evaluation approach. Results Six source documents from four trials ( n = 567) focusing on self-management, health information or physical activity were identified. The effects of web-based rehabilitation interventions on pain, function, quality of life, self-efficacy, rheumatoid arthritis knowledge and physical activity are uncertain because of the very low quality of evidence mostly from small single trials. Adverse effects were not reported. Conclusion Large, well-designed trials are needed to evaluate the clinical and cost-effectiveness of web-based rehabilitation interventions in rheumatoid arthritis.

    The purpose of this study was to compare functional magnetic resonance (MR) imaging of the motor cortex in healthy volunteers and patients with brain tumours. Functional MR imaging was performed in 14 healthy volunteers and 14 patients with tumours in or near the primary motor cortex with groups being matched for age, sex, and handedness. Functional images were acquired during motion of the right and left hand. Time courses of signal intensity within the contralateral, ipsilateral, and supplementary motor cortex as well as z-maps were calculated, their quality being assessed visually. Mean signal increase between activation and rest were evaluated within the contralateral, ipsilateral, and supplementary motor cortex, the activated area in those regions of interest was measured using z-maps. The quality of functional MR experiments was generally lower in patients than in volunteers. The quantitative results showed a trend towards increased ipsilateral activation in volunteers during left hand compared to right hand motion and in patients during motion of the affected compared to the non-affected hand. Considering quantitative and qualitative results, significantly increased ipsilateral activation was found in patients compared to healthy volunteers. In conclusion, functional MR imaging quality was significantly reduced in patient studies compared to healthy volunteers, even if influences of age, sex, and handedness were excluded. Increased ipsilateral activation was found in patients with brain tumours which can be interpreted by an improved connectivity between both hemispheres. (orig.)

    In 20 patients with paralysis, 25 regions were irradiated with (mostly) 10 Gy in single fractions of 2 to 2.5 Gy using 8 MW photons. In 15 patients radiotherapy was performed as a primary treatment in the status of myositis; 7 patients were treated after (subtotal) resection of already manifest ossifications (2 patients were treated twice, primarily and postoperatively). In a minimum follow-up 12 weeks, none of the 20 irradiated patients showed any progression of the developing or already manifest ossification; thus mobilisation and rehabilitation could be carried out as desired. No side effects occurred. The preliminary results of the present study suggest that radiotherapy is an effective local treatment with minimal side effects for the prevention of heterotopic bone formation in patients with paraplegia. (orig.) [Deutsch] Bei 20 Patienten (18 Maenner, zwei Frauen, Alter 19 bis 62 Jahre) mit Querschnittssyndrom wurden 25 Regionen mit ueberwiegend 10 Gy a 2 bis 2,5 Gy Einzeldosis mit 8-MW-Photonen bestrahlt. Die Radiatio erfolgte bei 15 Patienten als Primaerprophylaxe im entzuendlichen Stadium, bei sieben Patienten sekundaer nach (subtotaler) Resektion von Ossifikationen (zwei Patienten wurden sowohl primaer als auch sekundaer bestrahlt). Bei einer Mindestnachbeobachtungszeit von zwoelf Wochen trat in keinem Fall eine Progression der sich entwickelnden bzw. bereits bestehenden heterotopen Ossifikationen auf: saemtliche Patienten konnten wunschgemaess mobilisiert und im Rahmen ihrer neurologischen Ausfaelle rehabilitiert werden. Nebenwirkungen traten nicht auf. Die vorliegende praeliminaeren Ergebnisse deuten hin, dass die Strahlentherapie eine effektive und nebenwirkungsarme lokale Therapie zur Verhinderung heterotoper Ossifikationen beim Querschnittssyndrom darstellt.

    In a prospective study possible indications for MR arthrography of the shoulder were evaluated. 37 patients were examined before and after intraarticular administration of a 2-mmolar solution of Gd-DTPA. MR arthrography was performed if there was no joint effusion and/or an uncertain finding concerning the rotator cuff or the capsulolabral complex on plain MR images. MR arthrography leads to a better demonstration of labrum pathology in 11/22 patients and to a superior delineation of the capsuloligamentous apparatus in 20/22 cases. In 9/15 patients with impingement lesions MR arthrography allowed a differentiation of severe tendinitis from partial and small full-thickness tears of the rotator cuff. MR arthrography of the shoulder joint enhances the accuracy of MR in case of an uncertain finding on plain MR images. (orig.) [Deutsch] In einer prospektiven Studie sollten Einsatzmoeglichkeiten der MR-Arthrographie bei Erkrankungen des Schultergelenkes herausgearbeitet werden. 37 Patienten wurden sowohl nativ als auch nach intraartikulaerer Gabe einer 2mmolaren Gd-DTPA-Loesung untersucht. Voraussetzungen fuer die KM-Gabe waren ein fehlender Gelenkerguss und/oder ein unklarer Befund des Labrum-Kapsel-Komplexes oder der Rotatorenmanschette in der Nativuntersuchung. Durch die MR-Arthrographie wurde bei 11/22 Patienten eine verbesserte Darstellung der Labrumpathologie erzielt; in 20/22 Faellen ergabe sich eine zuverlaessige Beurteilung der Gelenkkapsel. Bei 9/15 Patienten mit Erkrankungen der Rotatorenmanschette konnten Tendinitiden von partiellen und kleinen kompletten Rotatorenmanschettenrupturen sicher differenziert werden. Die MR-Arthrographie des Schultergelenkes fuehrt bei nicht eindeutigen Befunden in der Nativuntersuchung zu einer verbesserten Treffsicherheit der MR-Diagnostik. (orig.)

    This study evaluates F-18-FDG PET of the thyroid in Graves` disease. Methods: Thirty patients were investigated the day before radioiodine therapy, 15 patients 3-10 days after radioiodine therapy. Twenty patients with cancer of the head or neck and normal thyroid function served as controls. Results: F-18-FDG uptake was higher in Graves` disease patients than in controls. Negative correlations of F-18-FDG uptake with half-life of radioiodine and absorbed radiation dose due to radioiodine therapy were found along with a positive correlation to autoantibody levels. Conclusion: Thus F-18-FDG PET is likely to give information on the biological activity of Graves` disease as well as on early radiation effects. (orig.) [Deutsch] Ziel: Diese Studie evaluiert F-18-Fluoro-Deoxy-Glukose (F-18-FDG) PET der Schilddruese bei Patienten mit M. Basedow. Methoden: 30 Patienten wurden am Tag vor Radioiod-Therapie, 15 Patienten am 3.-10. Tag nach Radioiodtherapie untersucht. 20 Patienten mit Kopf/Halstumoren und normaler Schilddruesenfunktion dienten als Kontrollgruppe. Ergebnisse: Die F-18-FDG-Aufnahme in der Schilddruese war signifikant hoeher bei Patienten mit M-Basedow im Vergleich zu den Kontrollen. Sie stieg mit hoeheren, antithyreoidalen Antikoerpern und sank bei laengerer I-131-Halbwertzeit. Es bestand eine Korrelation einer reduzierten Glukose-Utilisation bei hoeherer absorbierter Schilddruesendosis nach Radioiod-Therapie. Schlussfolgerung: Damit erscheint die F-18-FDG-PET-Untersuchung zur biologischen Aktivitaetsbeurteilung des M. Basedow und Darstellung von fruehen Strahleneffekten geeignet. (orig.)

  17. Digital tomosynthesis of hand joints for arthritis assessment

    The two principal forms of hand arthritis, rheumatoid arthritis (RA) and osteoarthritis (OA) have large clinical and economic costs. Radiography has been shown to be a useful tool to assess the condition of the disease. A hand radiograph, however, is a two-dimensional projection of a three-dimensional object. In this report we present the results of a study that applied digital tomosynthesis to hand radiography in order to extract three-dimensional outcome measures that should be more sensitive to arthritis progression. The study was performed using simulated projection radiographs created using micro computed tomography (μCT) and a set of five dry-bone hand skeletons. These simulated projection images were then reconstructed into tomographic slices using the matrix inversion tomosynthesis (MITS) algorithm. The accuracy of the tomosynthesis reconstruction was evaluated by comparing the reconstructed images to a gold standard created using the μCT data. A parameter from image registration science, normalized mutual information, provided a quantifiable figure of merit. This study examined the effects of source displacement, number of reconstructed planes, number of acquisitions, noise added to the gray scale images, and errors in the location of a fiducial marker. We also optimized the reconstruction as a function of two variables k and α, that controlled the mixing of MITS with conventional shift-and-add tomosynthesis. A study using hand delineated joint margins demonstrated that MITS images provided a better measurement of average joint space width. We found good agreement between the MITS slices and the true planes. Both joint margins and trabecular structure were visible and the reconstructed slices showed additional structures not visible with the standard projection image. Using hand-delineated joint margins we compared the average joint space width of the gold standard slices to the MITS and projection images. A root-mean square deviation (RMSD), calculated

    Risikostratifizierung von Noeten ist. Die klinische Untersuchung und die Bestimmung von Blutwerten dienen bei Diabetikern typischerweise zur Risikostratifizierung bzgl. kardio(zerebro)vaskulaerer Ereignisse in der Zukunft. Sowohl die Kardio- als auch die Ganzkoerper-MRT stellen standardisierte Verfahren in der klinischen Diagnostik dar. Deren Stellenwert bei der Vorhersage von Ereignissen mit entsprechender Risikostratifizierung bei Diabetikern gewinnt basierend auf aktuellen Studienergebnissen zunehmend an Bedeutung. Late Gadolinium Enhancement (LGE) im Kardio-MRT detektiert bei bis zu 30 % der Diabetiker stumme Myokardischaemien, die mit einer Hazard Ratio von 3-6 mit kardiovaskulaeren Ereignissen assoziiert sind. Ebenfalls zeigen linksventrikulaere Wandbewegungsstoerungen sowie eine erniedrigte Ejektionsfraktion einen prognostischen Wert. Im Ganzkoerper-MRT sind der Vessel-Score und Karotisstenosen zusaetzliche Praediktoren fuer kardio(zerebro)vaskulaere Ereignisse. Die MRT-basierte Vorhersage kardio(zerebro)vaskulaerer Ereignisse bietet einen signifikanten Mehrwert zur klassischen Risikostratifizierung bei Diabetikern. Jedoch erlaubt nur die umfassende Ganzkoerper-MRT-Untersuchung Patienten zu identifizieren, die ueber einen Zeitraum von 6 Jahren komplett frei von kardio(zerebro)vaskulaeren Ereignissen bleiben. Die Kardio-MRT, insbesondere die Erfassung von LGE, empfiehlt sich fuer die Vorhersage von Ereignissen. Die Ganzkoerper-MRT stellt einen prognostischen Mehrwert dar, deren klinische Relevanz in weiteren Studien geklaert werden muss. (orig.)

    Long since it have been suggested that a subpopulation of patients with rheumatoid arthritis (RA), diagnosed with negative rheumatoid factor (RF) tests, represents a clinical entity quite distinct from that of seropositive rheumatoid arthritis. The aim of the study was to establish a scientific comparative analysis between RA seronegative and seropositive, regarding course and prognoses of the disease. Two hundred fifty patients with rheumatoid arthritis according to the (American College of Rheumatology) criteria were retrospectively studied by analysis the course and prognoses of disease. All examinees were between 25-60 years of age (Xb=49.9, SD=10.3) with disease duration between 1-27 years (Xbox=6.41, SD=6.47). Course of the disease with "remissions and exacerbations", progressive continual course and bad prognoses, were more presented in seropositive group ofpatients. Partial remission was more common in seronegative patients but according to serostatus and gender has not shown statistically significant difference. Duration of the disease was a specific prognostic sign for both subsets [(r=0.32, p0.05) seronegative, (r=0.18, p<0.05) seropositive]. Seropositive and seronegative RA distinguish in course and prognostic feature, but not enough to differentiate them in two different forms of the disease. Regarding the sero-status, differences within sex, with some exceptions, are not relevant.

    Diagnosis of infection with help of antigranulocyte scintigraphy near body stem is difficult because of contemporary visualisation of bone marrow. Therefore, we investigated, whether it is possible to improve the accuracy in diagnosing septic loosening of hip endoprosthesis by changing the analyzing methods. Methods: In 28 patients, the results of a visual interpretation of late scan, a visual interpretation and a quantitative interpretation of time-activity-course were compared. These results were verified by histology respectively microbiology. Results: Histological and microbiological verification found 14 septic loosening and 14 aseptic loosening of the hip protheses. Therefore, sensitivity, specificity, negative and positive predictive value for the visual interpretation of late scan were 0.86, 0.57, 0.80 and 0.67. For visual and quantitative interpretation of time-activity-course we found 0.86, 0.79, 0.85 and 0.80 respectively 1, 0.93, 1, 0.93. For interobserver agreement we found kappa coefficients of 0.28 {+-} 0.2 for visual interpretation of late scan, 0.48 {+-} 0.17 for visual interpretation and 1.0 {+-} 0 for quantitative interpretation of time-activity-course. Conclusion: In all investigated values quantitative interpretation of time-activity-course was superior to the other analyzing methods. Therefore, antigranulocyte scintigraphy for septic loosening of hip endoprosthesis should be interpreted quantitatively. (orig.)

    The aim of this study was to provide practical information to angiographers concerning radiation exposure to body parts not covered by lead aprons. Individual doses to the neck and hands of radiologists measured in micro-Sieverts were obtained during the course of 80 angiographies of various types. The number of diagnostic and interventional procedures, which might lead to exceeding permissible doses, have been calculated. Possibilities of estimating doses during angiography by means of parameters such as screening times were examined statistically. Especially with regard to the hands, estimations of the doses are insufficient (correlation r=0.21). Radiologists who undertake much angiographic and particularly interventional work may reach exposure levels requiring protective measures in addition to lead aprons. (orig.) [Deutsch] Ziel dieser Studie ist es, dem angiographierenden Radiologen praktische Anhaltspunkte zur Einschaetzung der Strahlenexposition der nicht von der Bleischuerze abgedeckten Koerperteile zu geben. Bei 80 Angiographien aus einem breiten klinischen Spektrum wurden Einzeldosen in Mikro-Sievert an Hals und Hand des Radiologen gemessen. Fuer bestimmte Gruppen von diagnostischen und interventionellen Angiographien wurde die Anzahl der Untersuchungen hochgerechnet, die zu einer Ueberschreitung der Grenzwerte fuehren koennte. Die Moeglichkeit einer Schaetzung der Dosis anhand von Parametern der Angiographie, wie z.B. der Durchleuchtungszeit, wurde korrelationsstatistisch geprueft. Besonders fuer die Haende ist eine Schaetzung unzureichend (r=0,21). Kontinuierlich und viel angiographiende Radiologen koennen im diagnostischen, aber eher noch im interventionellen Bereich eine Groessenordnung erreichen, die Vorsichtsmassnahmen oder Zusatzmessungen ausserhalb der Bleischuerze sinnvoll erscheinen laesst.

    Aim: To demonstrate psychometric test and neuroimaging technic capacity in subclinical conditions of cerebral affection in patients with rheumatoid arthritis; to demonstrate agreement between topographic cerebral site and morphological signs in neuroimaging study; to evaluate agreement between cognitive deficits and rheumatoid severity. Material and Method: We have enrolled 20 patients, 17 pts. (85%) showed low score evocative for executive function limitation; 6 pts. (33%) showed attention anomaly, movement organization and verbal fluency. SPECT acquisition shows frontal lobe uptake in 95% (19/20 pts.) extended to parietal lobs in 42% (8/19pts.); 1 pt. Shows normal uptake and very high score. RMN study shows a specific sign of leukoencephalopaty in 35% (7/20pts.) and liquoral spaces increased in 25% (5/20 pts.). Conclusions: Frequent cognitive functions alteration during rheumatoid arthritis; very high topographic agreement between cognitive deficits and cerebral perfusion uptake showed by SPECT study; significant correlation between severity index and disease activity and cognitive deterioration; necessity of further longitudinal study for greater number of patient; pathogenetic disconnect mechanism cortical-subcortical by vasculitic reason or deafferentation jointed to negative interaction between motor limit and cognitive deficit

    Rheumatoid arthritis is the most common systematic autoimmune disease and its etiology is believed to have both strong genetic and environmental components. We demonstrate the utility of including genetic and clinical phenotypes as covariates within a linkage analysis framework to search for rheumatoid arthritis susceptibility loci. The raw genotypes of 1302 affected relative pairs were combined from four large family-based samples (North American Rheumatoid Arthritis Consortium, United Kingdom, European Consortium on Rheumatoid Arthritis Families, and Canada). The familiality of the clinical phenotypes was assessed. The affected relative pairs were subjected to autosomal multipoint affected relative-pair linkage analysis. Covariates were included in the linkage analysis to take account of heterogeneity within the sample. Evidence of familiality was observed with age at onset (p << 0.001) and rheumatoid factor (RF) IgM (p << 0.001), but not definite erosions (p = 0.21). Genome-wide significant evidence for linkage was observed on chromosome 6. Genome-wide suggestive evidence for linkage was observed on chromosomes 13 and 20 when conditioning on age at onset, chromosome 15 conditional on gender, and chromosome 19 conditional on RF IgM after allowing for multiple testing of covariates.

    Work was carried out on the serum of 100 healthy subjects and hundred Rheumatoid Arthritus patients by electrophoresis and atomic absorption model Hitachi-180-80. The different proteins fractions separated by electrophoresis were subjected for estimation of Cu-Concentration. It was found that only 5% copper is present in albumin which remains constant in normal and Rheumatoid Arthritus patients. The other important group of proteins were a2-globulins, in which Cu concentration was found high in Rheumatoid Arthritus patients as compared to normal subject. There was no copper detected in beta and gamma globulins. The study can be used for diagnostic purposes. Copper complexes of alpha 2-Globulins were found anti inflammatory in nature and this quality of self defense can bring revolution in the history of all infectious diseases including Rheumatoid Arthritus simply by separating the copper complexes of alpha 2-globulins (most probably ceruloplasmin) from the blood of donors and injecting into the body of patients. It is possible by this method that the disease-Rheumatoid Arthritus may be eradicated completely. These complexes have also shown antibiotic activity in gynae patients. (author)

    Laut einer Befragung im Jahre 2012 war der Umgang mit Antithrombotika bei dermatochirurgischen Eingriffen in Deutschland sehr heterogen. 2014 wurde erstmals eine evidenzbasierte Leitlinie zu diesem Thema veröffentlicht. Es wurde eine anonyme Befragung derselben Stichprobe zum Umgang mit Antithrombotika sowie zu Kenntnissen der Leitlinie durchgeführt. Die Ergebnisse wurden als relative Häufigkeiten berichtet und denen aus 2012 gegenübergestellt. 208 Antwortbögen wurden ausgewertet (Rücklaufquote: 36,6 %). Die große Mehrheit der Dermatologen erklärte, kleinere Eingriffe unter Fortführung der Therapie mit Phenprocoumon, niedrig dosierter Acetylsalicylsäure (≤ 100 mg) und Clopidogrel sowie mit direkten oralen Antikoagulanzien durchzuführen. Bei größeren Eingriffen war der Umgang hingegen weiterhin heterogen, insbesondere unter niedergelassenen Dermatologen. Der Anteil der Dermatologen, die Phenprocoumon, Acetylsalicylsäure und Clopidogrel leitlinienkonform verwendeten, hat sich insgesamt vergrößert. Führten 2012 beispielsweise 53,8 % der Klinikärzte bzw. 36,3 % der niedergelassenen Dermatologen eine große Exzision unter Fortführung der Therapie mit niedrig dosierter Acetylsalicylsäure durch, taten dies 2017 90,2 % bzw. 57,8 % (Phenprocoumon: 33,8 % bzw. 11,9 % auf 63,9 % bzw. 29,9 %; Clopidogrel: 36,9 % bzw. 23,2 % auf 63,9 % bzw. 30,6 %). Unter den Klinikärzten war ein hoher Anteil mit der Leitlinie vertraut und fand diese hilfreich. Eine Zunahme des leitlinienkonformen Verhaltens war bei allen Eingriffen zu verzeichnen. Bei größeren Eingriffen zeigte sich trotz deutlicher Verbesserung die Notwendigkeit verstärkter Anstrengungen zur Leitlinienumsetzung bzw. zur Identifizierung von Implementierungsbarrieren. © 2018 Deutsche Dermatologische Gesellschaft (DDG).

    Full Text Available Objectives: Muscle blood flow in the forearm of patients with rheuma-toid arthritis and healthy volunteers following treatment with temperature increasingarm baths, mudpacks and short- or decimeter-wave diathermy was studied in thisinvestigation. The aim of the study was to find out the difference of reactive hyperemia between the different temperature methods as well as the influence on theconsensual reaction. Subjects: Eighty patients with rheumatoid arthritis, stage 3 according toSteinbrocker, as well as 80 healthy human subjects had been assigned numerically in the four therapy- and controlgroups. Patients with diseases influencing the peripheral blood flow were excluded. Design: Blood flow was measured by venous occlusion plethysmography in both forearms with the subjects lyingsupine. The application of the local heat therapies had been excluded on the left forearm. The forearm blood flow wasmonitored before heat therapy, directly after as well as in two further 10 minutes intervals. An analysis of variancewas used to determine the influence on blood flow of the response to the heat therapies in patients with rheumatoidarthritis and healthy subjects.Results: Under homogeneous starting conditions and a statistically uniformed high blood flow in rest the reactive values of blood flow on the left-hand side of application and the right consensual side showed high significant differencesbetween all methods of therapy. Differences between the patients and the healthy subjects only showed tendencies withpartially lower reactions, concerning the patients with rheumatoid arthritis. All methods of heat therapy caused a statistically provable consensual reaction that turned out smaller after diathermic methods. Here the post therapeuticreaction of the blood flow on the side of application was also lower or rather shorter. Conclusion: Greater differences of the blood flow in rest between the patients with rheumatoid arthritis and healthysubjects

The results are similar to those of other authors. As compared to synovectomy radio-synoviorthesis seems less successful as far as long-term results are concerned. As local treatment radio-synoviorthesis seems a good supplementory element in the therapeutic plan of rheumatoid arthritis.

    Acceleration-deceleration rotational brain trauma is a common cause of disability or death in young adults and often leads to a focal destruction of axons. The resulting pathology, axonal shear injury is referred to as diffuse axonal injury (DAI). The DAI-associated lesions occur bilaterally, are widely dispersed and have been observed in the surface and deep white matter. They are found near to and far from the impact site. When DAI is clinically suspected, magnetic resonance imaging (MRI) is the method of choice for further clarification, especially in patients where cranial computed tomography (CT) is inconspicuous. To investigate the presence of DAI after traumatic brain injury (TBI), a multimodal MRI approach is applied including the common structural and also functional imaging sequences. For structural MRI, fluid-attenuated inversion recovery (FLAIR) weighted and susceptibility contrast imaging (SWI) are the sequences mainly used. The SWI technique is extremely sensitive to blood breakdown products, which appear as small signal voids at three locations, at the gray-white interface, in the corpus callosum and in the brain stem. Functional MRI comprises a group of constantly developing techniques that have great potential in optimal evaluation of the white matter in patients after craniocerebral trauma. These imaging techniques allow the visualization of changes associated with shear injuries, such as functional impairment of axons and decreased blood flow and abnormal metabolic activity of the brain parts affected. The multimodal MRI approach in patients with DAI results in a more detailed and differentiated representation of the underlying pathophysiological changes of the injured nerve tracts and helps to improve the diagnostic and prognostic accuracy of MRI. When DAI is suspected multimodal MRI should be performed as soon as possible after craniocerebral injury. (orig.)

    Full Text Available OBJECTIVE: To translate, to perform a cultural adaptation of and to test the reproducibility of the Cochin Hand Functional Scale questionnaire for Brazil. METHODS: First, the Cochin Hand Functional Scale questionnaire was translated into Portuguese and was then back-translated into French. These translations were reviewed by a committee to establish a Brazilian version of the questionnaire to be tested. The validity and reproducibility of the Cochin Hand Functional Scale questionnaire was evaluated. Patients of both sexes, who were aged 18 to 60 years and presented with rheumatoid arthritis affecting their hands, were interviewed. The patients were initially interviewed by two observers and were later interviewed by a single rater. First, the Visual Analogue Scale for hand pain, the Arm, Shoulder and Hand Disability questionnaire and the Health Assessment Questionnaire were administered. The third administration of the Cochin Hand Functional Scale was performed fifteen days after the first administration. Ninety patients were assessed in the present study. RESULTS: Two questions were modified as a result of the assessment of cultural equivalence. The Cronbach's alpha value for this assessment was 0.93. The intraclass intraobserver and interobserver correlation coefficients were 0.76 and 0.96, respectively. The Spearman's coefficient indicated that there was a low level of correlation between the Cochin Hand Functional Scale and the Visual Analogue Scale for pain (0.46 and that there was a moderate level of correlation of the Cochin Scale with the Health Assessment Questionnaire (0.66 and with the Disability of the Arm, Shoulder and Hand questionnaire (0.63. The average administration time for the Cochin Scale was three minutes. CONCLUSION: The Brazilian version of the Cochin Hand Functional Scale was successfully translated and adapted, and this version exhibited good internal consistency, reliability and construct validity.

    40 patients with SLE were assessed, the diagnoses being made according to modified ARA-criteria; the hand films of 25 of these patients were analysed. The most important roentgenologic findings consisted of reducible deformities with mild or absent articular changes in the deformed MCP and PIP joints. As these changes often occur late in the course of SLE, a primary radiological diagnosis was possible in only three cases (8%), whereas hand films provided confirmatory evidence of disease in a further seven patients. These roentgenological characteristics of SLE were found significantly less often in patients with definite RA; this group tended to have positive ANF (antinuclear factors). Antibodies against DNA may be absent, especially in a less active phase of disease. ANF is non-specific, and SLE simulates RA in 10-20% of cases. It is, therefore, very important in individual cases to consider the diagnosis of SLE in the presence of deformity without corresponding articular changes. Direct comparison of both the p.a. and oblique views is essential in the evaluation of reducible deformities, although this point has not been stressed in the literature. Reducible deformities may be overlooked in physical examination, when the patient gives no history of functional disability. The main differential diagnosis is Jaccoud's arthropathy, which is rarely seen in a general hospital. Most of these patients give a history of recurrent rheumatic fever, a minority complain about joint pain or disability, approximately 90% show signs indicating a valvular lesion of the heart, over 75% have a normal ESR and a positive rheumatoid or antinuclear factor is very rarely found. The distinction from SLE or rheumatoid arthritis is therefore easily established on additional non-radiological criteria.

    Optical imaging (OI) is a relatively new method in detecting active inflammation of hand joints of patients suffering from rheumatoid arthritis (RA). With the high number of people affected by this disease especially in western countries, the availability of OI as an early diagnostic imaging method is clinically highly relevant. In this paper, we present a newly in-house developed OI analyzing tool and a clinical evaluation study. Our analyzing tool extends the capability of existing OI tools. We include many features in the tool, such as region-based image analysis, hyper perfusion curve analysis, and multi-modality image fusion to aid clinicians in localizing and determining the intensity of inflammation in joints. Additionally, image data management options, such as the full integration of PACS/RIS, are included. In our clinical study we demonstrate how OI facilitates the detection of active inflammation in rheumatoid arthritis. The preliminary clinical results indicate a sensitivity of 43.5%, a specificity of 80.3%, an accuracy of 65.7%, a positive predictive value of 76.6%, and a negative predictive value of 64.9% in relation to clinical results from MRI. The accuracy of inflammation detection serves as evidence to the potential of OI as a useful imaging modality for early detection of active inflammation in patients with rheumatoid arthritis. With our in-house developed tool we extend the usefulness of OI imaging in the clinical arena. Overall, we show that OI is a fast, inexpensive, non-invasive and nonionizing yet highly sensitive and accurate imaging modality.-

    An association between periodontal disease and rheumatoid arthritis is believed to exist. Most investigations into a possible relationship have been case-control studies with relatively low sample sizes. The advent of very large clinical repositories has created new opportunities for data-driven research. We conducted a retrospective cohort study to measure the association between periodontal disease and rheumatoid arthritis in a population of 25 million patients. We demonstrated that subjects with periodontal disease were roughly 1.4 times more likely to have rheumatoid arthritis. These results compare favorably with those of previous studies on smaller cohorts. Additional work is needed to identify the mechanisms behind this association and to determine if aggressive treatment of periodontal disease can alter the course of rheumatoid arthritis.

    Full Text Available Abstract Background Anti-neutrophil cytoplasmic antibodies are typically detected in anti-neutrophil cytoplasmic antibody associated vasculitis, but are also present in a number of chronic inflammatory non-vasculitic conditions like rheumatoid arthritis. Rare cases of granulomatosis with polyangiitis (formerly known as Wegener’s granulomatosis, a vasculitic disorder frequently associated with the presence of anti-neutrophil cytoplasmic antibodies in patients with rheumatoid arthritis have been described in literature. Case presentation We report two middle-aged female patients with rheumatoid arthritis who developed anti-neutrophil cytoplasmic antibodies and symptoms reminiscent of granulomatosis with polyangiitis. Despite the lack of antibodies specific for proteinase 3 and the absence of a classical histology, we report a probable case of granulomatosis with polyangiitis in the first patient, and consider rheumatoid vasculitis in the second patient. Conclusion Taken together with previous reports, these cases highlight that anti-neutrophil cytoplasmic antibodies have to be evaluated very carefully in patients with rheumatoid arthritis. In this context, anti-neutrophil cytoplasmic antibodies detected by indirect immunofluorescence appear to have a low diagnostic value for granulomatosis with polyangiitis. Instead they may have prognostic value for assessing the course of rheumatoid arthritis.

    The purpose of this study was to explore the relationship between disability status and duration of morning stiffness in hands with regard to age, level of education, and gender in patients with rheumatoid arthritis (RA). Also, the authors wanted to investigate this relationship with regard to the presence of rheumatoid factor, i.e., the serological status. A retrospective study was conducted in 250 patients with the classic form of RA (186 females, s64 males, mean age Xb = 49.96 y ears, range 25-60 years, disease duration 1-27 years, Xb = 6.41) previously diagnosed with RA according to the ACR (American College of Rheumatology 1987 criteria). All patients were in Steinbrocker functional classes II and III. The probability level was expressed by p 0.05) seronegative, (r = 0.12, y = 0.00x + 2.30, p > 0.05) seropositive]. High positive values were obtained for the linear correlation coefficient between duration of the disease and functional class (p < 0.01). Also, high values were obtained regarding the coefficient of correlation between age and functional class [(r = 0.29, p < 0.01) seronegative, (r = 0.47, p < 0.01) seropositive]. Uneducated patients were significantly more represented in functional class III [ 23 (50%) seronegative, 19 (42.2%) seropositive] than in functional class II [16 (20.3%) seronegative, 22 (27.5%) seropositive]. In conclusion, in this study of patients with rheumatoid arthritis, increased duration of morning stiffness was associated with functional disability. Functional disability increased with the duration of the disease, depended on age and educational level, and was more pronounced in older age, regardless of RA serological status. With regard to serological status and sex, the differences were non-significant.

    Full Text Available Background: Rheumatoid arthritis (RA is an autoimmune disorder affecting nearly 1% of adult population. First-line therapies include disease-modifying antirheumatic drugs, but creno-balneotherapyis often prescribed in rheumatic disorders and RA is no exception. Objectives: To know the efficacy of creno-balneotherapy in RA. Methods: A Medline based search was made using MeSH terms “balneology” and “rheumatoid arthritis”. Articles concerning the use of mineral waters in RA treatment were included. Results: In RA, two traditional ways of employing mineral waters are commonly used: immersion and peliotherapy. Each owns their benefits to non-specific or hydrotherapeutic effects and specific or crenotherapeutic effects. Mineral waters must be regarded as an adjuvant therapy in quiescent, stable or non-progressive RA. Significant benefits have been accomplished with radonenriched and sulphurous waters. Isothermal or hyperthermal waters should be preferred. Conclusions: Although there is a global lack of evidence, mineral waters are a safe and effective therapy to be considered in RA.

    Altered body composition is a frequent finding in rheumatoid arthritis and is associated with the two major outcomes of the disease: disability and cardiovascular mortality. It is estimated that up to two thirds of patients may be affected by loss of lean mass, the so-called rheumatoid cachexia. Hence, body weight being equal, the relative amount of lean mass is lower and that of body fat is higher in rheumatoid arthritis patients vs. healthy controls. Both disease-related factors and other factors, like drug treatments, physical activity and nutrition contribute to modify body composition in rheumatoid arthritis. The effect of pharmacological treatments, and notably of anti-TNF drugs, on body composition is controversial. Conversely, training programs to stimulate muscle growth can restore lean mass and reduce adiposity. There is good evidence that amelioration of body composition ameliorates function and reduces disability. Currently, there is no evidence that interventions that modify body composition can reduce cardiovascular morbidity and mortality in rheumatoid arthritis. Copyright © 2015.

    The current popular GNSS RTK technique would be not applicable on ocean due to the limited communication access for transmitting differential corrections. A new technique is proposed for high-precision ocean RTK, referred to as ORTK, where the corrections are transmitted by employing the function of BeiDou satellite short-message communication (SMC). To overcome the limitation of narrow bandwidth of BeiDou SMC, a new strategy of simplifying and encoding corrections is proposed instead of standard differential corrections, which reduces the single-epoch corrections from more than 1000 to less than 300 bytes. To solve the problems of correction delays, cycle slips, blunders and abnormal epochs over ultra-long baseline ORTK, a series of powerful algorithms were designed at the user-end software for achieving the stable and precise kinematic solutions on far ocean applications. The results from two long baselines of 240 and 420 km and real ocean experiments reveal that the kinematic solutions with horizontal accuracy of 5 cm and vertical accuracy of better than 15 cm are achievable by convergence time of 3-10 min. Compared to commercial ocean PPP with satellite telecommunication, ORTK is of much cheaper expense, higher accuracy and shorter convergence. It will be very prospective in many location-based ocean services.

    Rheumatoid arthritis preferrably becomes manifest at the synovial joints of the limbs, especially at the small joints of the hands and feet, at bursae and synovial sheathes. The pathologic lesions are less frequently found at cartilaginous joints or entheses. The lesions very often are symmetrically distributed and are characterized by the following: 1. A periarticular, spindle-shaped opacity with a density similar to soft-tissue, induced by an inflammatory hypertrophy of the synovia, a serosynovitis, or an edematous impregnation of the periarticular tissue. 2. A juxta-articular osteoporosis, most probably caused by a neighbouring synovialitis accompanied by hyperemia. 3. A diffuse joint cavity narrowing due to a destruction of the articular cartilage by the pannus, a fibrovascular resorptive tissue. 4. Central as well as marginal erosions, caused by destruction of ossous material by the pannus. 5. Subchondral signal cysts, likewise unduced by the pannus. (Orig./AJ) [Deutsch] Die rheumatoide Arthritis manifestiert sich bevorzugt an den synovialen Gelenken der Extremitaeten, insbesondere an den kleinen Gelenken der Haende und Fuesse, an Bursae und an Sehnenscheiden. Seltener finden sich pathologische Veraenderungen an kartilaginaeren Gelenken und an Enthesen. Die Gelenkveraenderungen an Haenden und Fuessen sind oft symmetrisch verteilt und durch folgende Veraenderungen gepraegt: 1. Einer partikulaeren, spindelfoermigen weichteildichten Verschattung, hervorgerufen durch eine entsuendliche Hypertrophie der Synovia, einen Gelenkerguss und einer oedematoesen Durchtraenkung des perartikulaeren Gewebes. 2. Einer gelenknahen Osteoporose, deren Ursache die benachbarte Synovialitis mit Hyperaemie sein duerfte. 3. Einer diffusen Gelenkspaltverschmaelerung des Gelenkknorpels durch den Pannus, einem fibrovaskulaeren Resorptivgewebe. 4.

    Background: Osteoporosis is an early and common feature in rheumatoid arthritis. Apart from other manifestations, Osteoporosis is an extra-articular manifestation of rheumatoid arthritis which may result in increased risk of fractures, morbidity, mortality, and associated healthcare costs. This study evaluates bone mineral density changes in patients with rheumatoid arthritis of recent-onset. Methods: This descriptive case series was conducted in the Rheumatology Department of a tertiary care hospital in Karachi. Data was prospectively collected from 76 patients presenting with seropositive or seronegative rheumatoid arthritis. Bone mineral density of these patients measured at lumbar spine and hip by using dual energy x-ray absorptiometry scan. Variables like age, gender, BMI, menstrual status, disease duration, erythrocyte sedimentation rate, vitamin D level, clinical disease activity index and seropositivity for rheumatoid arthritis were measured along with outcome variables. Results: A total of 104 patients fulfilling inclusion criteria were registered with 28 excluded from study. Among the remaining 76 patients, 68 (89.50 percentage) were female, with mean age of patients (with low bone mineral density) as 50.95±7.87 years. Nineteen (25 percentage) patients had low bone mineral density, 68.52 percentage had low BMD at spine while 10.52 percentage at hip and 21.05 percentage at spine and hip both. Low bone mineral density was found higher in patients with seronegative 7 (50 percentage) as compared to seropositive patients 12 (19.4 percentage) (p-value 0.017), whereas low bone mineral density was found higher 12 (70.6 percentage) among post-menopausal women. Conclusion: Low BMD was found in 25 percentage of patients at earlier stage of the rheumatoid arthritis with seropositivity, age and menopausal status as significant risk factors. (author)

    Full Text Available De acordo com a literatura existente, as informações contábeis representam um importante estimador dos fluxos de caixa futuros da empresa, servindo, portanto, para fins de avaliação do risco de um investimento em ações. Isso porque tais informações refletem a realidade econômico-financeira da empresa em um dado período, possuindo, consequentemente, relação com o risco sistemático de um investimento, o que justifica sua utilização para fins de decisões relacionadas à composição de um portfólio de ações. Dentro desse contexto, o presente trabalho busca apresentar evidências empíricas da relação entre as informações contábeis e o risco sistemático no mercado brasileiro. Mais especificamente, objetiva-se analisar a relação entre os betas contábeis e os betas de mercado de companhias no Brasil. Para isso, foram selecionadas 97 empresas, da Bolsa de Valores, Mercadorias e Futuros de São Paulo (BM&FBOVESPA, de 15 setores econômicos, entre o 1º trimestre de 1995 e o 3º trimestre de 2009. Foram utilizadas 468 variáveis contábeis. Para operacionalizar a relação entre as variáveis foi utilizado um modelo de regressão com dados em painel. Os resultados evidenciaram que alguns betas contábeis podem explicar o beta de mercado e podem fazê-lo de forma antecipada, podendo, ainda, melhorar a previsão do beta de mercado quando associados a betas de mercado históricos. Por outro lado, a maior parte das versões de betas contábeis apresentou relação pouco significativa ou mesmo inexistente.

    Ultrarelativistische Schwerionenstöße werden seit etwa 15 Jahren untersucht, um Kernmaterie unter extremen Bedingungen zu erforschen; in Kollisionen schwerer Atomkerne kann bei hohen Einschußenergien Kernmaterie stark komprimiert und aufgeheizt werden. Die Bedeutung dieser Experimente wird durch Berechnungen der Quanten-Chromo-Dynamik auf raumzeitlichen Gittern hervorgehoben, die bei ausreichend hoher Energiedichte eine Phase voraussagen, in der die Quarks nicht mehr in Hadronen gebunden sind, sondern zusammen mit den Gluonen ein partonisches System ausbilden. Ist das System hinreichend groß und equilibriert, wird es als Quark-Gluon-Plasma bezeichnet. Die als Signatur für das Überschreiten der Phasengrenze vorgeschlagene erhöhte Produktion Seltsamkeit tragender Teilchen wurde in der Gegenüberstellung von elementaren Proton+Proton-Interaktionen und Kern+Kern-Stößen experimentell über einen weiten Energiebereich bestätigt.

    Changes in the production of immunoglobulins and rheumatoid factors (RF's) were studied in 20 patients with intractable rheumatoid arthritis (RA) following total doses of 750 rad or 2,000 rad lymphoid irradiation. Over a 12 month follow up period there was no consistent change in absolute serum or synovial fluid levels, or in synovial membrane production of either total IgG, IgA or IgM, or the corresponding RF fractions. The in-vitro production of immunoglobulins and IgM RF by peripheral blood mononuclear cells was also unaltered, except for one patient who had a dramatic rise in IgM RF production. Over the same period there was a significant overall reduction in disease activity following both doses of radiotherapy. It is concluded that the clinical response which occurs following lymphoid irradiation is not due to a reduction in RF production. Furthermore, the production of RF's appears to be unaffected by the changes in T cell immunity which occur following lymphoid irradiation. (author)

Hematological abnormalities such as anemia may occur in up to 65% of the patients, with chronic disease anemia being the commonest form. Autoimmune hemolytic anemia can be associated with different connective tissue diseases, particularly systemic lupus erythematosus and it is part of its classification criteria. On the other hand, the presence of autoimmune hemolytic anemia in rheumatoid arthritis has rarely been described in the literature and the pathogenic mechanisms for its development remain unclear. We describe here a case of rheumatoid arthritis and another of juvenile rheumatoid arthritis that developed to autoimmune hemolytic anemia and present the probable etiopathogenic mechanisms.

    Rheumatoid arthritis (RA) is a chronic systemic autoimmune disease of the connective tissue, which results in disability and earlier death. Thus it is very important to recognise this pathologic condition as early as possible, to lessen and delay its consequences. Currently, magnetic resonance imaging is the best imaging modality, depicting every stage of this disease and allowing for monitoring of the treatment response. The process of standardisation is needed in assessing MR pictures. The aim of this article was to present the MR protocols of hand and wrist MR examinations for rheumatologic demand and standards of results, according to worldwide OMERACT RAMRIS 2002 and supplemented by tenosynovitis system.

    Purpose: The radiotherapeutic possibilities are limited for patients with a recurrent or second head and neck cancer if the patient was already irradiated in the first therapy. In the presented study we investigated the changes of this situation due to the usage of amifostine in the case of re-irradiation (simultaneous radio-chemotherapy). Patients and methods: Between 1995 and 1997 we treated 14 patients with a recurrent or second malignancy of the head and neck region by a simultaneous radio-chemotherapy (20x1.5 Gy, Carboplatin 70 mg/m{sup 2} BSA on days 1 to 5 and 16 to 20, 500 mg amifostine prior to every carboplatin infusion). Six out of 14 patients got an additional brachytherapy (10 to 15 Gy) to increase the local dose because of a residual tomor. In 4 cases the treatment was an adjunctive one, following the surgical tumor debulking. Results: We have seen 3 complete remissions (21.4%), and 8 partial remissions (57.1%). The median time of observation in 13 months now. Three out of 14 patients died, 2 because of the tumor. Hematological toxicities: Side effects Grade 2 WHO were seen only in 1 patient. Acute non-hematological toxicities: Mucositis Grade 0/1 in 7 patients, mucositis Grade 2 in 7 patients, dysphagia Grade 0/1 in 9 patients, dysphagia Grade 2 in 5 patients, xerostomia Grade 1 in 9 patients, xerostomia Grade 2 in 3 patients. We registrated only 1 serious late toxicity due to radio-chemotherapy: 4 months after brachytherapy a patient (with laryngectomy) developed a submental fistula. Conclusion: These first results suggest that the usage of amifostine offers new potential ways for re-irradiation of patients with recurrent or second malignancies in the head neck region. (orig.)

    Advanced and specialized radiological diagnostics are essential in the case of clinical suspicion of pediatric injuries to the head, thorax, abdomen, and extremities when there is no case history or when ''battered child syndrome'' is assumed on the basis of inadequate trauma. In particular, the aim of this sophisticated diagnostic procedure is the detection of lesions of the central nervous system (CNS) in order to initiate prompt medical treatment. If diagnostic imaging shows typical findings of child abuse, accurate documented evidence of the diagnostic results is required to prevent further endangerment of the child's welfare. (orig.)

    Coeliac disease has a significant association with many autoimmune disorders. It shares many common genetic and immunological features with other autoimmune diseases. Gluten, a gut-derived antigen, is the driver of the autoimmunity seen in coeliac disease. The altered intestinal permeability found in coeliac patients, coupled with a genetic predisposition and altered immunological response, may result in a systemic immune response that is directed against sites other than the gut. Gut-derived antigens may have a role in the pathogenesis of other autoimmune disorders including rheumatoid arthritis. Here we report a case of adult coeliac disease associated with rheumatoid arthritis.

    Objective: To evaluate frequency of fibromyalgia in rheumatoid arthritis and its effect on disease activity score. Study Design: Cross-sectional study. Place and Duration of Study: The Indus Hospital, Karachi, from December 2010 to May 2011. Methodology: All adult patients of either gender diagnosed as rheumatoid arthritis on the basis of clinical, laboratory and X-ray criteria were included in the study. The sample data was separated into two groups depending on presence or absence of fibromyalgia and 28 joint disease activity score (DAS-28) value was evaluated. Results: There were 31 (25.83%) patients with rheumatoid arthritis and fibromyalgia (RAFM) out of the total 120. The median (IQR) age of patients was 40 (32 - 51) years. All were females. The overall female frequency was 79 (88.8%). The median (IQR) DAS-28 score in RA group was 4.9 (3.66 - 5.71), while the median (IQR) DAS-28 score in RAFM was 7.04 (6.62 - 7.64) [p < 0.0001]. The number of patient getting combination therapy of DMARD in RAFM group was 61.3% while in RA group was 42.7%. Conclusion: DAS-28 was found to be significantly higher in RAFM patients probably because of higher perception of pain. (author)

    The purpose of this study is to describe the appearance of tenosynovitis in various tendon groups in the wrist and hand and to compare MR enhanced and non-enhanced imaging evaluation of tenosynovitis of hand and wrist in inflammatory arthritis. We reviewed 72 MRI studies of hands and wrists, including coronal, axial and sagittal images in 30 consecutive patients with inflammatory arthritis and tenosynovitis. We compared the degree of synovitis on T2-weighted vs contrast-enhanced T1-weighted images, using a predetermined scale. We also measured the extent of tenosynovitis in three dimensions. The tendons were assigned to volar, dorsal, ulnar and radial groups in the wrist and to extensor, flexor and thumb groups in the hand. Degree of tenosynovitis (graded 0-3), cross-sectional area and volume of the inflamed synovium in various tendon groups were then compared by statistical analysis. Review of the medical records revealed the following diagnoses in our patient population: rheumatoid arthritis (n=16), unspecified inflammatory polyarthritis (n=9), psoriatic arthritis (n=2), CREST syndrome (n=1), systemic lupus erythematosus (n=1), paraneoplastic syndrome with arthritis (n=1). The average T2 brightness scores and post-gadolinium enhancement scores were 1.0 and 1.7 respectively (P<0.001) in the wrist studies. The average T2 brightness scores and post-gadolinium enhancement scores were 0.7 and 1.4, respectively (P<0.001) in the hand studies. The average sensitivity of T2-weighted imaging for detection of tenosynovitis was 40% in the hand and 67% in the wrist tendons, when contrast-enhanced images were used as a reference. Carpal tunnel flexor tendons were the most frequently affected tendons of the wrist. The most frequently affected tendons of the hand were second and third flexor tendons. The hand flexors demonstrated higher degrees of enhancement and larger volumes of the inflamed tenosynovium than did the hand extensors and tendons of the thumb.

The average T2 brightness scores and post-gadolinium enhancement scores were 0.7 and 1.4, respectively (P<0.001) in the hand studies. The average sensitivity of T2-weighted imaging for detection of tenosynovitis was 40% in the hand and 67% in the wrist tendons, when contrast-enhanced images were used as a reference. Carpal tunnel flexor tendons were the most frequently affected tendons of the wrist. The most frequently affected tendons of the hand were second and third flexor tendons. The hand flexors demonstrated higher degrees of enhancement and larger volumes of the inflamed tenosynovium than did the hand extensors and tendons of the thumb

    wichtige Ursache von Schlaganfaellen bei juengeren Erwachsenen. Wir untersuchten die diagnostischen Moeglichkeiten der Magnetresonanzangiographie (MRA) in Kombination mit der Magnetresonanztomographie (MRT) bei vertebrobasilaeren Dissektionen anhand einer retrospektiven Analyse von 24 Patienten mit einer Vertebralisdissektion und einem Patienten mit einer Basilarisdissektion. Bei 24 von 25 Patienten (95,5%) wurden mit der Magnetresonanzangiographie abnorme Flussverhaeltnisse im disseziierten Gefaess erkannt. Die Sensitivitaet der konventionellen Angiographie war 100% und die des Ultraschalls 77%. In 7 Faellen (30,4%) ergab die Magnetresonanz spezifische Hinweise auf eine Dissektion (Doppellumen n=1, murales Haematom n=4, Pseudoaneurysma n=2). Demgegenueber standen 36,4% spezifische Befunde in der Angiographie. Dabei waren die spezifischen Resultate von MRT/MRA und Angiographie z.T. komplementaer, beide Methoden zusammen erzielten 43,5% Spezifitaet. Die kombinierte MRT und MRA kann bei etwa 1/3 der Patienten bereits die Diagnose einer Vertebralisdissektion stellen. Bei den anderen Patienten kann die Indikation zur konventionellen Angiographie verbessert werden. Dies gilt besonders fuer jene Patienten mit unspezifischen Prodromalsymptomen. Eine negative Magnetresonanzuntersuchung erzetzt bei Patienten mit hinweisenden Symptomen die konventionelle Angiographie allerdings nicht. Die Angiographie wird aufgrund der hoeheren Ortsaufloesung und der sicheren Beurteilbarkeit auch des proximalen V Abschnittes 1 vorerst diagnostischer Standard bleiben. (orig.)

    Full Text Available This cross-sectional study is conducted to determine the prevalence of asymptomatic cervical spine subluxation in rheumatoid arthritis patients by plain radiographs and its relation to demographic and clinical characteristics, disease activity measures and medications. 100 rheumatoid arthritis patients (18 male and 82 female were selected randomly, according to the American college of Rheumatology Criteria, who were under follow up in the rheumatology clinic. A complete history was taken, and physical examination has been done with focus on the cervical spine to determine their demographic data, disease duration, age of disease onset, drug history, swollen and tender joint counts, and ESR, Hb, CRP, RF levels. The disease activity of patients with rheumatoid arthritis was measured using the disease activity score 28. Radiographs of the cervical spine included lateral views taken in flexion, extension, neutral position of the neck and anterioposterior and odontoid projection view. Asymptomatic cervical spine subluxation was found in 17 of the 100 patients (17%. The prevalence of, anterior atlantoaxial subluxation, atlantoaxial impaction and subaxial subluxation was 10(10%, 5(5% and 6(6%, respectively. Posterior subluxation was not detected. The only characteristic that showed meaningful relationship with cervical spine subluxation was CRP (P=0.036. Our results showed that patients with RA, who have cervical spine subluxation cannot be distinguished on the basis of symptoms. Cervical spine involvement is common and may be asymptomatic, indicating routine cervical spine imaging is needed in patients with RA.

    Aim: To examine all cases with Graves` disease after radioiodine therapy of autonomously functioning thyroid tissue (AFFT) in order to find the cause. Methods: We retrospectively studied 1428 pts who were treated between 11/93 and 3/97 with radioiodine for AFTT and who underwent at least one control examination. Results: 15 (1.1%) of all pts developed Graves` disease 8.4 (4-13) months after radioiodine therapy. There was no direct suggestion of Graves` disease (TRAK negative, no endocrine ophthalmopathy) in any pt at the time of radioiodine therapy. More detailed analysis of anamnestic data, however, revealed evidence that immunothyropathy predated radioiodine therapy in 11 of the 15 pts. Paradoxical effects of radioiodine therapy manifested as an increase in immunothyropathy 14 pts, a deterioration in metabolism in 11 pts and a first occurrence of endocrine ophthalmopathy in 5 pts. Conclusion: Exacerbation of preexisting, functional primarily insignificant immunothyropathia is held responsible in most cases for the observed paradoxical effects after radioiodine therapy, resulting in radiation-induced manifest Graves` disease; however no therapeutical consequences are recommended. (orig.) [Deutsch] Ziel: Erfassung von Pat. mit einer nach Radiojodtherapie wegen einer funktionellen Autonomie aufgetretenen Immunhyperthyreose sowie deren Ursachen.

Ergebnisse: 15 (1,1%) der Pat. entwickelten 8,4 (4-13) Monate nach Radiojodtherapie eine postradiogene Immunhyperthyreose. Bei allen 15 Pat. lag zum Zeitpunkt der Radiojodtherapie kein direkter Hinweis auf eine Immunhyperthyreose vor (TRAK neg., keine endokrine Orbitopathie). Bei einer genauen Analyse anamnestischer Daten fanden sich jedoch bei 11 der 15 Pat. erste Hinweise auf das Vorliegen

    To determine the presentation patterns, biologically vulnerable patient groups and treatment strategies of rheumatoid arthritis. The retrospective study was conducted at the Rheumatology Clinic of Liaquat National Hospital and Medical College, Karachi, and comprised data of rheumatology patients who presented between September 2006 and September 2012. After screening all the files, rheumatoid arthritis cases were identified. Data collection was done using a questionnaire that included patient demographics, co-morbidities, clinical manifestations and drug therapy. SPSS 13 was used for statistical analysis. Of the 2300 files screened, 500(21.7%) related to patients of rheumatoid arthritis. The mean age at presentation of these 500 patients was 41±15 years. There were 367(73.4%) women and they presented at an earlier age compared to men (p<0.024). Erosions were present in 198(40%) patients on X-rays and 22(4.4%) had joint deformities. Seropositive rheumatoid arthritis was associated with higher erythrocyte sedimentation rate levels (p<0.014), but did not differ from seronegative rheumatoid arthritis in terms of Disease Activity Score-28 levels (p<0.21). The skewed gender distribution was likely an effect of rheumatoid arthritis biology rather than due to issues of healthcare accessibility. Seronegative RA is likely to present late though it is as destructive as the seropositive disease.

    Specific objective was to develop the layout and structure of a platform for effective quantification of rheumatoid arthritis (RA). A fully operative Java stand-alone application software (RheumaCoach) was developed to support the efficacy of the scoring process in RA (Web address: http://www.univie.ac.at/radio/radio.htm). Addressed as potential users of such a program are physicians enrolled in clinical trials to evaluate the course of RA and its modulation with drug therapies and scientists developing new scoring modalities. The software 'RheumaCoach' consists of three major modules: The Tutorial starts with 'Rheumatoid Arthritis', to teach the basic pathology of the disease. Afterwards the section 'Imaging Standards' explains how to produce proper radiographs. 'Principles - How to use the 'Larsen Score', 'Radiographic Findings' and 'Quantification by Scoring' explain the requirements for unbiased scoring of RA. At the Data Input Sheet care was taken to follow the radiologist's approach in analysing films as published previously. At the compute sheet the calculated Larsen-Score may be compared with former scores and the further possibilities (calculate, export, print, send) are easily accessible. In a first pre-clinical study the system was tested in an unstructured. Two structured evaluations (30 fully documented and blinded cases of RA, four radiologists scored hands and feet with or without the RheumaCoach) followed. Between the evaluations we permanently improved the software. For all readers the usage of the RheumaCoach fastened the procedure, all together the scoring without computer-assistance needed about 20 % percent more time. Availability of the programme via the internet provides common access for potential quality control in multi-center studies. Documentation of results in a specifically designed printout improves communication between radiologists and rheumatologists. The possibilities of direct export to other programmes and electronic

    Sarcoidosis and amyloidosis are both multisystem disorders, which may involve the heart; however, isolated cardiac disease is rare. Diagnosis of cardiac sarcoidosis and amyloidosis is crucial because the patient prognosis is dependent on cardiac involvement and early treatment. Echocardiography is the first line imaging modality in the diagnostic work-up of both diseases, possibly giving hints towards the correct diagnosis. Besides myocardial biopsy and radionuclide studies cardiac magnetic resonance imaging (MRI) is routinely performed in patients suspect of having infiltrative cardiomyopathy. The T1 mapping procedure is currently being evaluated as a new technique for detection and quantification of global myocardial enhancement, as seen in cardiac amyloidosis. Sensitivities and specificities for detection of cardiac sarcoidosis and amyloidosis can be significantly improved by MRI, especially with late gadolinium enhancement (LGE) imaging. In cardiac sarcoidosis the use of LGE is outcome-related while in amyloidosis analysis of T1-mapping may be of prognostic value. If cardiac involvement in sarcoidosis or amyloidosis is suspected cardiac MRI including LGE should be performed for establishing the diagnosis. (orig.) [German] Die Sarkoidose und Amyloidose sind Multisystemerkrankungen, in deren Verlauf es zu einer kardialen Beteiligung kommen kann.

Als neuere Technik zur Darstellung globaler diffuser Kontrastmittelanreicherungen, wie sie im Rahmen der Amyloidose vorkommen, wird z. Z. das T1-Mapping evaluiert. Durch den Einsatz der MRT, insbesondere des Late-Gadolinium-Enhancements (LGE), koennen die Sensitivitaet und Spezifitaet in der Diagnostik der kardialen Sarkoidose und Amyloidose entscheidend verbessert werden. Bei der Sarkoidose stellt das Vorhandensein eines LGE einen

    Somatostatin receptor scintigraphy with {sup 111}In-labeled octreotide proves to be a very sensitive diagnostic tool for evaluation of inflammative activity in endocrine ophthalmopathy (EO). The results of somatostatin receptor scintigraphy (SRS) in 40 patients with EO show a high orbital accumulation of {sup 111}In-octreotide in clinically active EO (4h-median/orbit-brain-ratio: 12.6; controls 4h-median: 5.8) Patients with clinically inactive EO (4h-median: 7.1) show a similar orbital accumulation of radioactivity compared to controls. 5 patients with active orbital myositis also revealed an even higher orbital accumulation of radioactivity (4h-median: 42.3). The diagnostic value of SRS lies in its ability to act as a measure of inflammation and an be useful as an activity parameter when planning therapeutic procedure as well as for EO follow-up. The results in patients with orbital myositis nevertheless do not permit a differential diagnosis with this method. The therapeutic value of {sup 111}In-octreotide in Graves` disease has yet to be established. (orig.) [Deutsch] Die Somatostatin-Rezeptor-Szintigraphie (SRS) mit dem {sup 111}Indium-markierten Somatostatinanalogon Octreotid stellt ein sensitives Verfahren zur Einschaetzung der entzuendlichen Aktivitaet bei endokriner Orbitopathie (EO) dar. Die Untersuchungen an 40 Patienten mit EO ergaben eine im Vergleich zur Kontrollgruppe signifikant hoehere orbitale Octreotidanreicherung bei klinisch aktiver Erkrankung (4h-Median/Orbita-Hirn-Quotient: 12,6; Kontrollgruppe 4h-Median: 5,8; p=0,0032). Patienten mit klinisch nicht aktiver Erkrankung (4h-Median: 7,1) unterschieden sich bezueglich der orbitalen Octreotidanreicherung nicht wesentlich von der Kontrollgruppe. Auch 5 Patienten mit florider orbitaler Myositis zeigten eine deutlich gesteigerte orbitale Aktivitaetsanreicherung (4h-Median: 42,3). Der diagnostische Nutzen der SRS liegt somit in ihrer Eigenschaft als Aktivitaets- und Entzuendungsparameter und kann mit

    Full text: Polymyalgia rheumatica (PMR) and rheumatoid arthritis (RA) are clinical diagnoses that may be difficult to differentiate in the elderly RA can present with a polymyatgic onset, and the manifestations of PMR include peripheral synovitis. HLA DR4 alleles are over-represented in both diseases The APF is a serum antibody against profilaggrins which is detected by binding to cytoplasmic granules in buccal mucosal cells It is found in a high percentage (78%) Of both seropositive and seronegative rheumatoid arthritis patients. We studied the APF in 17 patients with PMR (by Hunder criteria). 13 age and sex matched patients with RA (by ACR criteria) and 10 healthy controls, to see whether the presence of APF could help distinguish PMR from RA. APF was assayed using a standard buccal mucosal cell-based immunofluorescence technique Rheumatoid factor was measured by latex agglutination and by ELISA. 11/13 (85%) Of the RA patients were APF positive, of which 6/11 (55%) were strongly positive. 13/17 (76%) Of the PMR patients were positive but none of these were strongly positive Of the controls 2/10 (20%) were positive. APF had a sensitivity of 87% and specificity of 67% for PMR and a sensitivity of 85% and specificity of 80% for RA. The combination of an APF and an RA latex test resulted in a sensitivity of 82% and specificity of 0% for RA patients. We conclude that the presence of APF does not distinguish RA from PMR. This study provides additional evidence that RA and PMR are related diseases

    Dyslipidaemia is one of the main risk factors for atherosclerotic cardiovascular disease. Patients with rheumatoid arthritis have 2-3 times more cardiovascular risk, which is partly due to the pattern of lipids which increase the atherogenic index. A descriptive, cross-sectional, observational and prospective study was conducted on 82 patients, selected for their lipid profile. Variables associated with the disease and the drugs used were recorded. Atherogenic risk was calculated, with Chi square being used for categorical variables, and the Mann-Whitney test for the continuous ones. The dyslipidaemia frequency was 54.9%. The most frequent age range of dyslipidaemia was between 51 and 60 years. Patients with type i obesity had a higher frequency of dyslipidaemia. Less dyslipidaemia was found with a lower rate of disease activity. Patients with cyclic citrullinated anti-peptide antibodies and positive rheumatoid factor, erythrocyte sedimentation rate>13mm or CRP>2mg/L had a higher frequency of dyslipidaemia. The mean Castelli atherogenic index was 4.36, the index of Kannel was 2.59, and triglycerides/HDL-c ratio was 3.83.Patients with dyslipidaemia showed a higher frequency of positive rheumatoid factor (P=.0008), and those patients who were taking hydroxychloroquine had a lower frequency of dyslipidaemia P=.03. Patients with rheumatoid arthritis have a pro-atherogenic lipid profile. It is important to know this and treat it to reduce cardiovascular risk.

    2002-01-01

    The cervical spine is a common focus of destruction from rheumatoid arthritis, second only to the metacarpophalangeal joints. Joint, bone and ligament damage in the cervical spine leads to subluxations which can cause cervical cord compression resulting in paralysis and even sudden death. Because many patients with significant subluxations are asymptomatic, the radiologist plays a key role in recognizing the clinically important clues to instability on plain radiographs of the cervical spine-often difficult in rheumatoid arthritis when the bony landmarks are osteoporotic or eroded. This review focuses on the signs of instability on plain radiographs of the cervical spine, using diagrams and clinical examples to illustrate methods of identifying significant subluxations in rheumatoid arthritis.

    An increased understanding in the pathophysiology of chronic inflammatory diseases, such as rheumatoid arthritis, reveals that the diseased tissue and the increased presence of macrophages and other overexpressed molecules within the tissue can be exploited to enhance the delivery of nanomedicine. Nanomedicine can passively accumulate into chronic inflammatory tissues via the enhanced permeability and retention phenomenon, or be surface conjugated with a ligand to actively bind to receptors overexpressed by cells within chronic inflammatory tissues, leading to increased efficacy and reduced systemic side-effects. This review highlights the research conducted over the past decade on using nanomedicine for potential treatment of rheumatoid arthritis and summarizes some of the major findings and promising opportunities on using nanomedicine to treat this prevalent and chronic disease.

    Aim: Multiple chemical sensitivity (MCS) is a controversially discussed symptom complex. Patients afflicted by MCS react to very low and generally non-toxic concentrations of environmental chemicals. It has been suggested that MCS leads to neurotoxic damage or neuroimmunological alteration in the brain detectable by positron emission tomography (PET) and single photon emission computer tomography (SPECT). These methods are often applied to MCS patients for diagnosis, although they never proved appropriate. Method: We scanned 12 MCS patients with PET, hypothesizing that it would reveal abnormal findings. Results: Mild glucose hypometabolism was present in one patient. In comparison with normal controls, the patient group showed no significant functional brain changes. Conclusion: This first systematic PET study in MCS patients revealed no hint of neurotoxic or neuroimmunological brain changes of functional significance. (orig.) [German] Ziel: Multiple chemische sensibilitaet (MCS) ist ein umstrittenes Krankheitsbild, das durch Reaktionen auf geringe, fueer Normalpersonen unschaedliche Mengen an Umweltchemikalien gekennzeichnet ist. Es wurde postuliert, dass MCS zu neurotoxischer Schaedigung bzw. neuroimmunologischer Veraenderung im Gehirn fuehrt, die mittels funktioneller bildgebender Verfahren, z. B. positronenemissionstomographie (PET), single-photon-emissions-computer-tomographie (SPECT) dargestellt werden koennte. Obwohl hierfuer kein wissenschaftlicher Beleg erbracht wurde, werden diese Methoden vielfach diagnostisch bei MCS-Patienten eingesetzt. Methode: Wir untersuchten 12 MCS-Patienten mit PET, um etwaige funktionelle Hirnveraenderungen nachzuweisen. Ergebnisse: Im Einzelvergleich war bei einem Patienten ein diskreter Glukose-Hypometabolismus in einzelnen Hirnregionen vorhanden. Im Gruppenvergleich konnte keine signifikante Abweichung von der Norm gefunden werden. Schlussfolgerung: Diese erste systematische PET-Studie bei MCS-Patienten erbrachte keinen

    Full Text Available The objective was to evaluate the frequency of cardiovascular risk factors and hypertension in patients with rheumatoid arthritis depending on body weight. The study involved 100 patients with rheumatoid arthritis and stably selected therapy for more than 6 months at the age from 45 to 65 years (mean age 53,19 ± 5,40 years. Traditional cardiovascular risk was assessed, taking into account risk factors by SCORE scale and amended for patients with RA. The levels of total cholesterol, triglycerides, C-reactive protein, serum creatinine, body mass index, body area index were determined. Arterial hypertension was diagnosed in 41 (41% patients with rheuma¬toid arthritis and was associated with traditional risk factors (age, obesity, rheumatoid factor, hyperuricemia and the duration of glucocorticoid therapy. Obesity and excess body mass occurred in the majority of patients with rheumatoid arthritis, herewith the highest level of inflammation indicators and risk of cardiovascular events was in overweight patients. Obesity was associated with duration of rheumatoid arthritis, the activity of the inflammatory process, the duration of glucocorticoids taking. It is found that the traditional SCORE scale does not fully reflect the risk of cardiovascular events in rheumatoid arthritis. Identification of hypertension and obesity increases the information content of the risk assessment of cardiovascular events in rheumatoid arthritis.

    To compare as proof of concept the sensitivity to change of automated quantification of radiographic wrist and hand joint space width (JSW) with scoring JSW according to the Sharp/van der Heijde scoring method (SHS) in two strategy groups of a treat-to-target and tight-control early rheumatoid arthritis (RA) study. Digital radiographs were assessed for JSW changes of 134 patients of the 236 patients participating in the second Computer Assisted Management in Early Rheumatoid Arthritis trial, of whom both baseline and year 2 radiographs were available (year 1 radiographs n=125). Of those 134 patients, 70 started with methotrexate and prednisone (MTX+Pred) and 64 with MTX and placebo (MTX+Plac). JSW change over 1 and 2 years of the hands and wrists was assessed, applying both the joint space narrowing (JSN) subscore of the SHS by 2 readers and the automated assessment with the JSW quantification software 'JSQ'. For both methods, progression of JSW change of the hand and wrist was analysed using linear mixed modelling (dependent variable 'JSW', factor 'strategy group', covariate 'follow-up time in years', interaction term 'strategy group*follow-up time'; radiographs of baseline, year 1 and year 2 were used). For each method the standardised mean difference (SMD) for the change in JSW from baseline to year 2 between the treatment strategies was obtained using a non-parametric method. Patient characteristics of the current subpopulation were similar to those of the whole study population. JSN of the hand and wrist according to SHS at 2 years was present in 16 vs. 23% in the MTX+Pred group vs. the MTX+Plac group. The mean yearly progression rates of JSW change of the hands and wrists using JSQ were -0.00mm (95% confidence interval (CI) -0.01; 0.01) for MTX+Pred vs. -0.02mm (95%CI -0.03; -0.01) for MTX+Plac, p=0.045, and using SHS JSN they were 0.19 units (95%CI 0.09; 0.30) vs. 0.30 units (95%CI 0.14; 0.45) for MTX+Pred vs. MTX+Plac, p=0.271.

    We report the case of a 50-year-old female smoker with an 11-year history of seropositive rheumatoid arthritis (rheumatoid factor and anti-cyclic citrullinated peptide antibodies) receiving triple therapy. She developed pulmonary nodules diagnosed as Langerhans cell histiocytosis by lung biopsy. We found no reported cases of the coexistence of these two diseases. Smoking abstinence led to radiologic resolution without modifying the immunosuppressive therapy.

    Background: Beta emitting {sup 106}Ru applicators manufactured by Bebig GmbH (Berlin, Germany) are widely used to treat intraocular tumors. The applicators are fixed to the bulbus and removed after several days. The following therapy relevant defects have been detected by an internal clinical acceptance test: risk of leakage and inconsistent dose-rate specifications by the manufacturer. In the meantime, components of the internal clinical acceptance test have been adopted successfully by the manufacturer of the {sup 106}Ru ophthalmic plaques. Material and Method: {sup 106}Ru ophthalmic plaques were tested with the following internal clinical acceptance tests: visual inspection, surface contamination, leakage, and dose-rate verification. The surface contamination test consists of a wet wipe test at moderate pressure. For the leakage test of the {sup 106}Ru ophthalmic plaques a clinically relevant scenario was developed in which the contact of the applicator with human tissue is simulated. In the course of it the applicator is inserted into Ringer's solution for several days. The certified energy dose-rate statements of the manufacturer are examined with a 1 mm{sup 3} plastic scintillator for consistency. (orig.) [German] Hintergrund: {sup 106}Ru-Augenapplikatoren der Fa.

    Systemic blockade of TNF-α in Rheumatoid arthritis with insulin resistance seems to produce more improvement in insulin sensitivity in normal weight patients with Rheumatoid arthritis than in obese patients with Rheumatoid arthritis, suggesting that systemic-inflammation and obesity are independent risk factors for insulin resistance in Rheumatoid arthritis patients. To evaluate the insulin resistance in: normal weight patients with Rheumatoid arthritis, overweight patients with Rheumatoid arthritis, obese Rheumatoid arthritis patients, and matched control subjects with normal weight and obesity; and its association with major cytokines involved in the pathogenesis of the disease. Assessments included: body mass index, insulin resistance by Homeostasis Model Assessment, ELISA method, and enzymatic colorimetric assay. Outstanding results from these studies include: (1) In Rheumatoid arthritis patients, insulin resistance was well correlated with body mass index, but not with levels of serum cytokines. In fact, levels of cytokines were similar in all Rheumatoid arthritis patients, regardless of being obese, overweight or normal weight (2) Insulin resistance was significantly higher in Rheumatoid arthritis with normal weight than in normal weight (3) No significant difference was observed between insulin resistances of Rheumatoid arthritis with obesity and obesity (4) As expected, levels of circulating cytokines were significantly higher in Rheumatoid arthritis patients than in obesity. Obesity appears to be a dominant condition above inflammation to produce IR in RA patients. The dissociation of the inflammation and obesity components to produce IR suggests the need of an independent therapeutic strategy in obese patients with RA. Copyright © 2017.

    The rheumatoid arthritis is a clinical entity capable to cause hearing impairment that can be diagnosed promptly with high frequencies audiometry. To detect subclinical sensorineural hearing loss in patients with rheumatoid arthritis. Cross-sectional study on patients with rheumatoid arthritis performing high frequency audiometry 125Hz to 16,000Hz and tympanometry. The results were correlated with markers of disease activity and response to therapy. High frequency audiometry was performed in 117 female patients aged from 19 to 65 years. Sensorineural hearing loss was observed at a sensitivity of pure tones from 125 to 8,000 Hz in 43.59%, a tone threshold of 10,000 to 16,000Hz in 94.02% patients in the right ear and in 95.73% in the left ear. Hearing was normal in 8 (6.84%) patients. Hearing loss was observed in 109 (93.16%), and was asymmetric in 36 (30.77%), symmetric in 73 (62.37%), bilateral in 107 (91.45%), unilateral in 2 (1.71%), and no conduction and/or mixed hearing loss was encountered. Eight (6.83%) patients presented vertigo, 24 (20.51%) tinnitus. Tympanogram type A presented in 88.90% in the right ear and 91.46% in the left ear, with 5.98 to 10.25% type As. Stapedius reflex was present in 75.3 to 85.2%. Speech discrimination in the left ear was significantly different (p = 0.02)in the group older than 50 years. No association was found regarding markers of disease activity, but there was an association with the onset of rheumatoid arthritis disease. Patients with rheumatoid arthritis had a high prevalence of sensorineural hearing loss for high and very high frequencies. Copyright © 2015 Academia Mexicana de Cirugía A.C.

    Dementia-inducing conditions represent a leading cause of disability and are a major health concern in industrialized countries. The burden these conditions put on society is certain to rise in the context of an ever-increasing elderly population. As these conditions feature an insidious onset and overlapping clinical features, imaging is a powerful tool in refining the diagnosis and assessing the progression of dementing conditions. The radiologist needs to be aware of and be able to detect underlying pathologies which could be reversible. Furthermore, imaging is important not only in excluding other pathologies but also in improving diagnostic accuracy. This article presents the typical clinical presentations as well as magnetic resonance imaging (MRI) features of the degenerative and the non-degenerative causes of dementia. The focus is on the core knowledge for MRI diagnostics in dementing conditions and a brief presentation of the latest MRI techniques which may become a part of standard imaging protocols in the future. (orig.) [German] Demenzielle Erkrankungen gehoeren in den Industrielaendern zu den haeufigsten Ursachen fuer Beeintraechtigungen im Alltag.

    Japanese physicians of Edo Period (1603-1867) wrote many dietetic books, by combining the knowledge system (content and compiling style) and thoughts of diet therapy from China with local condition in Japan. Among them, the Pao chu bei yong wo ming ben cao ( Japanese Materia Medica Prepared for Kitchen ), written by Mukai Genshou, a physician in the early Edo, is the earliest comprehensive work of dietetic materia medica. In this book, the choice and usage of Japanese dietetic materia medica reveals obvious Japanese local color, including the name, morphology, cultivation, collection, identification, nature and flavor, and indication etc., reflecting the sprouting idea of edible herbal plant at the beginning of Edo period and the characteristic of absorbing Chinese diet thoughts by Japanese physician. This is the important first-hand historical material to understand the development of Japanese dietetic herbalism in early Edo and its dietotherapy culture.

    Purpose: to assess whether MRI can detect atrophy of the trigeminal nerve in patients with trigeminal neuralgia. Materials and methods: a prospective MRI study was conducted in 39 patients (trigeminal neuralgia, trigeminal neuropathy, or atypical facial pain) and 25 volunteers. Using a coronal orientation (T1 flash 3D; T2 CISS 3D), regions of interest were delineated in the cisternal part of the trigeminal nerve along the border of the nerve to calculate the volume of the nerve. The volume of the nerve was compared side-by-side in each patient (t-test, p < 0.05) and the volume difference compared between patients and volunteers. Results: the volume of the compromised trigeminal nerve in patients with trigeminal neuralgia was lower than on the contralateral healthy side, with the difference between healthy and compromised side statistically significant (p < 0.05). In all other patients and in all volunteers, no significant difference was found between the volume of the healthy and compromised nerve. The volume difference between the healthy and compromised side in patients with trigeminal neuralgia was significantly higher (p < 0.05) than in all other patients and volunteers. Conclusion: atrophy of the trigeminal nerve caused by a nerve-vessel conflict can be detected by MRI. Only patients with trigeminal neuralgia show this unilateral atrophy. Therefore, it is possible to demonstrate the result of the nerve-vessel conflict and to determine the consequences of such a conflict. (orig.)

    The Routine Assessment of Patient Index Data 3 (RAPID3) is a patient-reported disease activity measure used to assess physical function, pain, and global health in patients with rheumatoid arthritis (RA) without formal joint counts. Since hand involvement and its decreased function are hallmarks of RA, the aim of our study was to investigate the performance of RAPID3 scores with regard to hand function and to confirm previous findings that the RAPID3 score as a disease activity measure is strongly correlated with the DAS28 score. Sixty-eight consecutive patients with RA (85% female), aged 18-75 years, were included in the study and were recruited during their outpatient visit. Apart from demographic and clinical data, the obtained parameters of interest included RAPID3 scores and assessments of the function of the hand, namely, the signal of functional impairment (SOFI)-hand, grip strength, and pulp-to-palm distance, as well the Health Assessment Questionnaire- Disability Index (HAQ-DI) and DAS28 scores. Pearson's correlation coefficient, Student's t test and linear regression were used in the statistical analysis of the results. The significance was set to p < 0.05. A positive correlation was found between RAPID3 scores and HAQ-DI scores, SOFI-hand scores, and pulp-to-palm distance, and negative correlation was observed between RAPID3 scores and grip strength. The order regarding the strength of correlations between RAPID3 scores and other variables (from the strongest to the weakest) was as follows: HAQ-DI, grip strength, SOFI-hand and pulp-to-palm distance. The hand assessment variables had stronger correlations with RAPID3 scores than with DAS28 scores. Our preliminary study showed that RAPID3 scores were strongly correlated with measurements of the functional ability of the hand, demonstrating that RAPID3 can be used as a measure of disease activity in clinical practice and to characterize hand function. Further studies are needed to confirm this result.

    A patient with thyroid carcinoma had abnormal accumulation of I-131 in the areas of both feet and hands on whole body scan. The sites of abnormal accumulation of I-131 were similar to those on bone scintigraphy. The radiographic examination of the lesions showed characteristic findings of rheumatoid arthritis, and the presence of small gold needles for acupuncture treatment was demonstrated. There were no findings of bone metastases. Although the mechanism of accumulation of I-131 in this patient is unknown, interpreters of I-131 whole body scintigraphs should keep this case in mind when acupuncture treatment has been done. The authors can only speculate on a common blood flow mechanism for enhanced HMDP and I-131 uptake in this arthritic patient who had been treated by acupuncture

    Purpose of review This review was conducted to focus on the recent clinical and translational research related to the associations between periodontal disease and rheumatoid arthritis. Recent findings There is a growing interest in the associations between oral health and autoimmune and inflammatory diseases. A number of epidemiologic studies have described associations between rheumatoid arthritis and periodontal disease. Recent clinical studies continue to support these reports, and are increasingly linked with biological assessments to better understand the nature of these relationships. A number of recent studies have evaluated the periopathogenic roles of Porphyromonas gingivalis, the oral microbiome, and mechanisms of site-specific and substrate-specific citrullination. These are helping to further elucidate the interactions between these two inflammatory disease processes. Summary Studies of clinical oral health parameters, the gingival microenvironment, autoantibodies and biomarkers, and rheumatoid arthritis disease activity measures are providing a better understanding of the potential mechanisms responsible for rheumatoid arthritis and periodontal disease associations. The cumulative results and ongoing studies have the promise to identify novel mechanisms and interventional strategies to improve patient outcomes for both conditions. PMID:23455329

    We report on the utility of the modified Breen method in addition to the Sauve-Kapandji operation for the treatment of instability and pain in the proximal ulnar stump in rheumatoid arthrities (RA) wrist. We treated a total of 15 hands in 12 patients with disturbances due to instability and pain at the proximal ulnar stump. The average follow-up period was 47 months. We evaluated the range of motion, grip strength, radioulnar distance, and the radioulnar distance at the stump using CT during pronation, supination, and neutral positions of the forearm in 11 of the 15 operated hands. We observed that none of the patients showed any signs of pain at the proximal ulnar stump and no scallop sign was observed. In all the cases, the line connecting the center of the radial head to the proximal ulnar stump served as the axis of rotation for the forearm; this was confirmed by the CT images. We concluded that our operative method resulted in stabilization of the proximal ulnar stump and recovery of powerful grip without pain during forearm rotation. (author)

    Aim: To determine the effect of external beam radiotherapy on subfoveal choroidal neovascularization in age-related macular degeneration. Patients and methods: Between September 1995 and July 1996, 40 patients (9 males and 31 females; mean age 74 years, range 61 to 83 years) were included in a prospective study. Eight patients had classic, well defined neovascularisations, 32 patients had occult lesions. Complete ophthalmic investigations included visual acuity contrast sensitivity as well as fluorescein and indocyanine green angiographic examinations prior to treatment and 1, 3, 6, and 12 months after radiotherapy. External beam radiotherapy (8-MV photons) was delivered with a total dose of 14.4 Gy in 8 fractions of 1.8 Gy per day. The field size averaged 5.5x4.5 cm. Results: No treatment related morbidity during or after treatment was obtained. After 6 months follow-up the visual acuity was improved in 2 (5%) patients and maintained at pretreatment level in 17 (42%) patients. However, 12 months post treatment a stable situation was found in 6 (15%) patients and a decrease in visual acuity in 34 (85%) patients. The central visual fields deteriorated significantly from 16.5 decibel (dB) to 12.4 dB. The enlargement of exsudats and neovascular membranes increased 5- to 7-fold. At 12 months after treatment, 3 (7.5%) patients stated that they had improved vision subjectively, 12 (30%) patients had no change and 25 (62.5%) patients suffered from subjective decrease in visual acuity. Conclusions: Using a total dose of 14.4 Gy/1.8 Gy no difference concerning visual acuity and exsudative changes in comparison to the natural history on age-related macular degeneration was obtained after 12 months. However, the results of multicenter studies are to be awaited. (orig.)

    Full Text Available Background: The high incidence of Rheumatoid Arthritis (RA, the conventional treatments and the experimental observations have shown that by taking particular foods or omitting some foods form ordinary diet, the disease symptoms of the patients reduce. The interesting point is that fasting lowers the objective and subjective indexes of disease activities in most patients who suffer from rheumatoid arthritis. The effects of a short-time fast and subsequent vegetarian diets for one year, on the rheumatoid arthritis patients were studied in this research. Materials and Methods: 52 patients (40 females and 12 males with definite rheumatoid arthritis, based on the American College of Rheumatology (ACR criteria were selected and duly studied with single blind method. 28 patients were selected after one month fasting at Ramadan. From the tenth day, a vegetarian diet was prescribed for them. This diet was continued for three moths. After three moths, the diet was changed to a combination of milk, vegetables and fruits. Two of the patients left the study at the end of Ramadan. A group of 24 non-fasting patients with ordinary food diet were selected as control group. Results: In the patients subject of study (with the average age of 39+14.5 and average 36 months disease, after four weeks of fasting under vegetarian diet, significant improvement was found in many of their disease indexes based on ACR criteria, such as joint pain and joint swelling, length of morning stiffness and responds to a health evaluation questionnaires. These suitable effects have still remained the same after one year. With respect to the findings, it is concluded that fasting and a changed diet had left significant effects on all calculated indexes. Although short time fasting had suitable effects in most patients suffering from rheumatoid arthritis, almost in all cases, the disease recurred when the patient returned to his/her ordinary food diet. Conclusion: The results of the

    Full Text Available Objective: To investigate ankle tenosynovitis in rheumatoid arthritis patients, regarding its presence, the kind of tendon involved and the concordance between clinical and ultrasound findings. Methods: Twenty patients with rheumatoid arthritis and pain or swollen ankle joint were evaluated. Tendon involvement was evaluated with ultrasound imaging. The Health Assessment Questionnaire (HAQ was performed for disability evaluation. Age, sex, disease duration, and vocational activity levels were also obtained. The statistical analysis included Fisher’s exact test. The significance level was 0.05. Results: Tenosynovitis was found in 13 of 20 (65.0% patients in 19 joints, in which 6 were bilaterally (46.1% and unilateral in 7 (53.8%. Tibialis posterior tenosynovitis was seen in nine (45.0% patients, Achilles tenosynovitis in seven (35.0%, tibialis anterior tenosynovitis in three (15.0%, and peroneal tenosynovitis in three (15.0% patients. We found concordance between symptomatic ankle and ultrasonographic findings in 92.3% of the patients with tenosynovitis. Association between severe HAQ with tendon involvement was not found (p>0.05. Disease duration was not associated with tenosynovitis. Patients were predominantly older, female, with mean age around 50.8 years. The long disease duration of patients presented a mean of 11.4 years and, most of them, with no vocational activity (65.0%. Conclusions: The results indicate that ankle tenosynovitis is very common in rheumatoid arthritis patients, both unilateral and bilateral. Tibialis posterior was the most common tendon involvement found. Finally, we found concordance between the clinical and ultrasound findings in almost all rheumatoid arthritis patients with ankle tenosynovitis.

    Full Text Available BACKGROUND: To investigate the associations between HLA-DRB1 shared epitope (SE alleles and rheumatoid arthritis in subsets of rheumatoid arthritis defined by autoantibodies in three Asian populations from Malaysia. METHODS: 1,079 rheumatoid arthritis patients and 1,470 healthy controls were included in the study. Levels of antibodies to citrullinated proteins (ACPA and rheumatoid factors were assessed and the PCR-SSO method was used for HLA-DRB1 genotyping. RESULTS: The proportion of ACPA positivity among Malay, Chinese and Indian rheumatoid arthritis patients were 62.9%, 65.2% and 68.6%, respectively. An increased frequency of SE alleles was observed in ACPA-positive rheumatoid arthritis among the three Asian ethnic groups. HLA-DRB1*10 was highly associated with rheumatoid arthritis susceptibility in these Asian populations. HLA-DRB1*0405 was significantly associated with susceptibility to rheumatoid arthritis in Malays and Chinese, but not in Indians. HLA-DRB1*01 did not show any independent effect as a risk factor for rheumatoid arthritis in this study and HLA-DRB1*1202 was protective in Malays and Chinese. There was no association between SE alleles and ACPA- negative rheumatoid arthritis in any of the three Asian ethnic groups. CONCLUSION: The HLA-DRB1 SE alleles increase the risk of ACPA-positive rheumatoid arthritis in all three Asian populations from Malaysia.

    Using electric power permits energetic optimization of production processes in industry and trade. Because of the trend towards qualitatively high-grade products, the energy form electric power plays a key role. Increased power demand on the part of industrial customers coincides with increased competition in the energy supply sector at the national and international levels. Within short, therefore, these industrial customers may prompt a change in preferences at the supplier side. Utilities will adopt suitable marketing concepts in order to gain profile with their customers as service providers. Operating close to customers will essentially influence customer satisfaction and, thereby, customer loyalty.

    Full Text Available Einleitung und Hypothese: Fahrradfahren ist nicht nur ein immer beliebter werdender Freizeitsport, sondern auch ein immer intensiver genutztes Fortbewegungsmittel. Somit ist es mittlerweile von großer Bedeutung, herauszufinden, welchen negativen Einfluss das Fahrradfahren auf den menschlichen Körper hat. Dieser Review fasst die aktuelle Evidenz zur Epidemiologie, Therapie und Prävention der Genital- und Beckenbodenbeschwerden bei weiblichen Fahrradfahrerinnen zusammen.brMethoden: Zwei Metadatenbanken, OvidSP und Deutsches Institut für Medizinische Dokumentation und Information (DIMDI, wurden auf Studien durchsucht, die über Genital- und Beckenbodenbeschwerden bei weiblichen Fahrradfahrerinnen berichteten und mögliche Therapie- oder Prophylaxeansätze untersuchten. Für die Literaturrecherche wurden folgende Schlagwörter verwendet: „female“, „bicycling“, „pelvic floor“, „lower urinary tract symptoms“ und „vulvar diseases“.brErgebnis: Die Suche ergab 1219 Artikel. Nach Entfernen der Duplikate aus dem Ergebnispool wurden 763 Publikationen nach relevanten Titeln untersucht. Letztendlich konnten 12 Fachartikel für unser Review herangezogen werden. 10 Studien waren Beobachtungsstudien und 2 experimentell. Symptome, die hierbei mit Fahrradfahren assoziiert wurden, waren: Schmerz und Neuropathien in der Beckenbodenregion sowie urologische Dysfunktionen und Hautverletzungen. Breitere und konventionelle Sättel führten zu einer geringeren Symptomatik als Sättel mit einer Lochung sowie schmälere Sportsättel.brZusammenfassung: Die Qualität der gegenwärtigen Studien war im Allgemeinen niedrig. Dennoch gibt es Evidenz dafür, dass Radfahrerinnen unter sehr ähnlichen Symptomen leiden wie Radfahrer: von kleineren Hautläsionen bis hin zu neurologischen Beschwerden.

  4. Advanced imaging in rheumatoid arthritis. Part 2: Erosions

    2007-01-01

    Rheumatoid arthritis (RA) is a chronic and progressive inflammatory disorder primarily affecting the synovium. We now recognise that conventional radiographic images show changes of rheumatoid arthritis late after irreversible joint damage has occured. With the advent of powerful disease-modifying drugs there is a need for early demonstration of rheumatoid arthritis and to monitor progress of the disease and response to therapy. Advanced imaging techniques such as ultrasound and MRI have focussed on the demonstration and quanitification of synovitis and erosions and allow early diagnosis of RA. The technology to quantify synovitis and erosions is developing rapidly and now allows change in disease activity to be assessed. However, problems undoubtedly exist in quantification techniques and this review serves to highlight them. Much of the literature on advanced imaging in RA appears in rheumatological journals and may not be familiar to radiologists. This review article aims to increase the awareness of radiologists to this field and to encourage them to participate and contribute to the ongoing development of these modalities. Without this collaboration it is unlikely that these modalities will reach their full potential in the field of rheumatological imaging. This review is in two parts. This first part addresses synovitis imaging. The second part will look at advanced imaging of erosions in RA. (orig.)

  10. The diagnostic significance of the radiologic appearances of the hands in systemic lupus erythematosus (SLE)

    1980-01-01

    40 patients with SLE were assessed, the diagnoses being made according to modified ARA-criteria; the hand films of 25 of these patients were analysed. The most important roentgenologic findings consisted of reducible deformities with mild or absent articular changes in the deformed MCP and PIP joints. As these changes often occur late in the course of SLE, a primary radiological diagnosis was possible in only three cases (8%), whereas hand films provided confirmatory evidence of disease in a further seven patients. These roentgenological characteristics of SLE were found significantly less often in patients with definite RA; this group tended to have positive ANF (antinuclear factors). Antibodies against DNA may be absent, especially in a less active phase of disease. ANF is non-specific, and SLE simulates RA in 10-20% of cases. It is, therefore, very important in individual cases to consider the diagnosis of SLE in the presence of deformity without corresponding articular changes. Direct comparison of both the p.a. and oblique views is essential in the evaluation of reducible deformities, although this point has not been stressed in the literature. Reducible deformities may be overlooked in physical examination, when the patient gives no history of functional disability. The main differential diagnosis is Jaccoud's arthropathy, which is rarely seen in a general hospital. Most of these patients give a history of recurrent rheumatic fever, a minority complain about joint pain or disability, approximately 90% show signs indicating a valvular lesion of the heart, over 75% have a normal ESR and a positive rheumatoid or antinuclear factor is very rarely found. The distinction from SLE or rheumatoid arthritis is therefore easily established on additional non-radiological criteria. (orig./MG) [de

    Objective: To determine the spectrum of clinical presentation, laboratory parameters and drug therapy in patients with Juvenile Rheumatoid Arthritis (JRA). Study Design: Case series. Place and Duration of Study: The Children's Hospital and The Institute of Child Health, Lahore, from October 2008 to October 2011. Methodology: All patients who fulfilled the American College of Rheumatology criteria for JRA were enrolled. Their clinical features, investigations done and treatment received for JRA were noted. Statistical analysis of data was done on SPSS version 16.0 for obtaining descriptive statistics. Results: Out of 185 patients, 50.3% (n = 93) were females; 54% (n = 100) were between 10 - 15 years of age. Polyarthritis was found in 71.9% (n = 133) followed by oligoarthritis (22.7%, n = 42) and systemic onset disease (5.4%, n = 10). Morning stiffness (78%) and fever (68%) were the most common clinical presentations. All patients with systemic onset disease had fever (n = 10) followed by skin rash, hepatosplenomegaly and lymphadenopathy. Uveitis was found in 2 patients, and both belonged to the oligoarticular group. Rheumatoid factor was found in 10.27% (n = 19) of all patients. All patients were given non-steroidal anti-inflammatory drugs (NSAIDs). Disease modifying agents (methotrexate) were given to 43.8% (n = 81). Steroids were used in 61% (n = 113) of patients either with NSAIDs alone or NSAIDs plus methotrexate. Conclusion: Disease profile of JRA at the study centre showed that polyarthritis is the commonest type. Recognition of subtypes will help in planning the management of these patients. (author)

    The recently introduced horizontally open configuration imagers allow imaging of knee, hip or shoulder during whole range of motion, which is not possible in conventional MR imagers. Special joint motion devices can be used to provide accurate and reproducible studies. In cervical spine, functional MR imaging may be useful in evaluating alarligament stability in patients with late sequelae of a whiplash injury, and in patients with rheumatoid arthritis who are clinically suspected of having a cervical myelopathy or superior migration of the odontoid process. In shoulder, full range of motion abduction study may be helpful in assessing the supraspinatus tendon impingement. To evaluate patellofemoral malalignment, quadriceps loading is recommended since associated contracting muscles and related soft tissue structures can be evaluated. The position of the femoral head relative to the acetabulum during different positions can be assessed. Open-configuration scanners provide an access to patients during scanning procedure, and therefore permit interventional procedures to be monitored with MRI. Such interventions include aspiration cytology/biopsy and different drainage procedures. (orig.)

    The prevalence of clinically evident interstitial lung disease in patients with rheumatoid arthritis is approximately 10%. An additional 33% of undiagnosed patients have interstitial lung abnormalities that can be detected with high-resolution computed tomography. Rheumatoid arthritis-interstitial lung disease patients have three times the risk of death compared to those with rheumatoid arthritis occurring in the absence of interstitial lung disease, and the mortality related to interstitial lung disease is rising. Rheumatoid arthritis-interstitial lung disease is most commonly classified as the usual interstitial pneumonia pattern, overlapping mechanistically and phenotypically with idiopathic pulmonary fibrosis, but can occur in a non-usual interstitial pneumonia pattern, mainly nonspecific interstitial pneumonia. Based on this, we propose two possible pathways to explain the coexistence of rheumatoid arthritis and interstitial lung disease: (i) Rheumatoid arthritis-interstitial lung disease with a non-usual interstitial pneumonia pattern may come about when an immune response against citrullinated peptides taking place in another site (e.g. the joints) subsequently affects the lungs; (ii) Rheumatoid arthritis-interstitial lung disease with a usual interstitial pneumonia pattern may represent a disease process in which idiopathic pulmonary fibrosis-like pathology triggers an immune response against citrullinated proteins that promotes articular disease indicative of rheumatoid arthritis. More studies focused on elucidating the basic mechanisms leading to different sub-phenotypes of rheumatoid arthritis-interstitial lung disease and the overlap with idiopathic pulmonary fibrosis are necessary to improve our understanding of the disease process and to define new therapeutic targets.

    Full Text Available It is estimated that in Poland about 400,000 persons in general suffer from inflammatory joint diseases, including rheumatoid arthritis (RA. Epidemiological surveys documenting the frequency and disturbance of musculoskeletal disorders in the Polish population are few in number. Most of the estimations are based on epidemiological data from other countries (prevalence of 0.5–1%. According to the data of the National Health Fund in Poland 135,000–157,000 persons in total are treated because of rheumatoid arthritis per year [ICD10 (International Statistical Classification of Diseases and Related Health Problems: M05, M06]. In the case of this group of diseases indirect costs significantly outweigh the direct costs. Indirect costs increase together with activity level of the disease. The cost analysis of productivity loss of RA patients indicates that sickness absenteeism and informal care are the most burdensome. At the national level it amounts in total from 1.2 billion to 2.8 billion PLN per year, depending on the method of analysis. These costs could be significantly reduced through early diagnosis and introduction of effective treatment.
