Radiological articular involvement in the dominant hand in rheumatoid arthritis.

Scoring the severity of joint involvement in the x-rays of hands of patients with rheumatoid arthritis showed significantly greater joint destruction in the dominant hand. The difference was seen in all the joints, and especially in the wrists, but with the exception of the metacarpophalangeal joint of the thumb. The grip strength was not, however, different in the 2 hands.     

Xeroradiography in assessment of the rheumatoid hand.

Comparable conventional x-rays had xeroradiographs were obtained of the hands of 22 patients with rheumatoid arthritis. Each metacarpophalangeal and proximal interphalangeal joint was scored for juxta-articular osteoporosis, erosions, loss of joint space, soft tissue thickening, joint deformity, and osteophytes on a 0-3 scale. For 10 hands the films were reported again after 3 months, and each technique was reproducible. Comparison between the 2 radiographic techniques showed that overall they gave similar results, although osteoporosis was reported more frequently on conventional x-rays, and loss of joint space and synovial thickening on xeroradiographs.     

Cardiac involvement in rheumatoid arthritis. Followup study.

Initial studies from Bowman Gray School of Medicine showed that 18 of 30 patients with classic rheumatoid arthritis (RA) had cardiac involvement from their disease. These abnormalities were detected by echocardiography and consisted of mitral valve and/or pericardial abnormalities. All patients were followed for 4 years from the initial workup. Mitral valve abnormalities were seen on followup in 63% of the patients who initially showed this abnormality, while pericardial effusion remained in 20%. Pericardial thickening persisted in 6 of 7 patients. None of the patients developed constrictive pericarditis or heart failure. There was no definite correlation between persistence of these abnormalities and other clinical data, but it was noticed that patients who had persistent pericardial effusion and mitral valve abnormalities showed a higher number of involved joints and a higher erythrocyte sedimentation rate. The cardiac abnormalities described in this study have remained clinically insignificant in this population of RA patients.     

Symptomatic cardiac involvement in juvenile rheumatoid arthritis.

In a retrospective study of 172 patients with juvenile rheumatoid arthritis, symptomatic cardiac involvement occurred in 13 (7.6%) patients (11 systemic and 2 polyarticular). There was predominance of the male sex and in most patients the involvement occurred in the initial years of the disease. Pericarditis occurred in seven patients; perimyocarditis in four and myocarditis in two patients. In the follow-up, one of the patients with pericarditis died of an arrhythmia during pericardiocentesis for cardiac tamponade. Among the patients with myocarditis, three died of septicemia during active disease. One of these three patients had myocarditis associated with cardiac tamponade. Among the 172 patients with juvenile rheumatoid arthritis, five children died; four belonged to the symptomatic cardiac involvement group (P less than 0.001). Cardiac involvement, in particular myocarditis and cardiac tamponade, can be regarded as a factor of worse prognosis.     

Pulmonary involvement in patients with rheumatoid arthritis.

Vital capacity (VC) and single-breath diffusing capacity for carbon monoxide of the lungs (Dco) were measured and chest X-ray evaluated in 129 patients with rheumatoid arthritis (RA). 123 of them represented average RA patients, either hospitalized (84 patients, Group I) or outpatient material (39 patients, Group II). The remaining six patients (Group III) represented cases with marked changes in chest X-ray detected in an earlier study. Deviating findings in the 123 cases of Groups I and II were observed as follows: in one the lung function tests or X-ray examinations, 35%; abnormal X-rays, 18%; reduced VC or Dco, 28%; simultaneously low VC and Dco, 7%; and pathological findings in all three tests, 2%. Group III showed extremely low VC and Dco values. Changes in respiratory function involved restrictive impairment and diffusion defects, and the results further implied that restrictive changes develop early, whereas decreased diffusing capacity is associated with more advanced "rheumatoid lung". The disparity abnormal findings in chest X-ray changes and in lung function tests suggests that in examining pulmonary manifestations in patients witu RA, both radiographic methods and pulmonary function tests should be used for relevant evaluation.     

The distribution of radiological joint damage in the rheumatoid hand.

We report a detailed study of the relative distribution of joint damage, as assessed by erosion and joint space scores, in the proximal interphalangeal (PIP) and metacarpophalangeal (MCP) joints of the rheumatoid hand. Hand radiographs of 30 patients with erosive rheumatoid arthritis were studied. There was significantly more damage in the dominant hand. The little-finger PIP joints were more damaged and the thumb interphalangeal (IP) joints less damaged than the other PIP joints. The index and middle finger MCP joints were more damaged than the other MCP joints. There was a significant negative correlation between the erosion scores of the PIP and MCP joints of each individual digit, when digits with only minimal damage were excluded. These findings support the concept that joint damage in the rheumatoid hand is greater in those joints that are subjected to greater mechanical stresses, and that in any digital ray the damage is concentrated at either the IPI or MCP joint.     

The rheumatoid hand: orthotics as preventative.

The treatment of hand disease in patients with rheumatoid arthritis (RA), with focus on rehabilitation and splinting, is discussed. A review of the data on splinting of hands in RA is included, as is a review of methods for evaluating hand function and staging RA. Recommendations are made for splinting early in the disease course and prior to surgery, rather than late in the course of RA, in an effort to minimize contractures.     

Pulmonary involvement in rheumatoid arthritis

The primary objective of this investigation was to assess the relationships between clinical characteristics, lung involvement, and frequency of pulmonary involvement in rheumatoid arthritis (RA). Using high-resolution computed tomography (HRCT) and pulmonary function tests (PFT), we prospectively evaluated 52 patients with RA (eight males and 44 females, mean age 53.6 years). The HRCT was abnormal in 35 patients (67.3%), the most frequent abnormalities being reticulonodular patterns, which were found in 22 patients (62.9%), ground-glass attenuation (20%), and bronchiectasis (17%). In this group of patients, PFT results were normal in 13 patients (37%). Titers of rheumatoid factor and erythrocyte sedimentation rate were significantly higher in abnormal HRCT presence. Higher Larsens score, advanced age, and severe disease were significant risk factors for lung involvement (p<0.001, p<0.01, and p<0.01, respectively) and are suggested by our data to be statistically significant predictors of lung involvement in RA.     

Laryngeal involvement in rheumatoid arthritis

Laryngeal involvement was evaluated in 45 patients with moderately severe rheumatoid arthritis (RA). RA duration and severity, prior laryngeal symptoms, and abnormalities detected by concurrent indirect laryngoscopy (IL) and computerized tomography (CT) were noted and correlated with changes of basilar interstitial fibrosis (BPF) found by chest radiograph. Thirty-two percent had abnormalities detected by IL, 54% had abnormalities by CT, and 36% had BPF on chest radiographs. Comparison of these groups revealed: only two symptoms (sore throat and difficulty during inspiration) were predictive of abnormalities detected by IL; no symptoms predicted abnormalities on CT; IL and CT may show abnormalities in a large percentage of RA patients even in the absence of symptoms; IL tends to detect mucosal and gross functional abnormalities while CT detects structural lesions; BPF shown on chest radiographs in RA patients does not appear to be correlated with cricoarytenoid arthritis as defined by IL and CT.     

Heart involvement in rheumatoid arthritis

It is reported on the malignant course of a case of rheumatoid arthritis, in which the participation of the heart became the cause of death. Here it is stated that we certainly enlarge our knowledge on the participation of the heart by modern cardiological diagnostics, but therapeutically are not yet able to engage decisively in the fateful course of the systemic rheumatoid basic disease. Therefore, efforts about an early cardiologic diagnosis are at present not yet of therapeutic consequences.     

Cardiovascular involvement in rheumatoid arthritis

Cardiovascular (CV) disease morbidity and mortality are increased in patients with rheumatoid arthritis (RA) and much of the excess CV disease morbidity appears to be due to atherosclerosis. The pathogenesis of atherosclerosis (ATS) in RA is complex and there is increasing evidence that many factors including novel and traditional cardiovascular risk factors, RA treatments and the RA inflammatory disease process are involved in the development of CV disease in these patients. Of particular interest are the effects of chronic inflammation and immune dysregulation associated with RA. These have been shown to be associated with endothelial dysfunction, which is an early, potentially reversible, functional abnormality of the arterial wall. However, as several CV disease risk factors and drug prescribing are also influenced by RA disease severity it is very difficult to separate out the effects of the inflammatory disease burden on the cardiovascular system in RA.     

Laryngeal involvement in rheumatoid arthritis

Rheumatoid arthritis (RA) is a chronic inflammatory disease affecting the synovial membrane, which causes joint damage and bone destruction. Extra-articular manifestations are numerous, involving multiple organ systems. Rheumatoid nodules are common extra-articular findings occurring in 20% RA patients. They develop most commonly in pressure areas (elbows and finger joints) and may occasionally affect internal organs including pleura, lungs, meninges, larynx, and others. Furthermore, RA affects the ear, nose, and throat, causing various otorhinolaryngological symptoms. In this report we describe two patients with RA and laryngeal involvement, mostly rheumatoid nodule formation, with a review of the literature.
