Pericarditis in rheumatoid arthritis. A clinical and radiological study.

The annual incidence of clinically manifest pericarditis was found to be 0.34% in 157 females and 0.44% in 77 males with rheumatoid arthritis, observed for a mean time of 5.

Inflammatory hyperostosis and sclerosis of the clavicle.

Six cases with chronic inflammatory hyperostotic and sclerotic changes of the clavicle are reported. No causative organisms could be detected. Four patients had involvement of other bones including the thoracic spine, the femur, the tibia and the sternal end of the other clavicle.

Joint fluid after aspiration. A disturbing factor in knee arthrography.

The amount of fluid in the knee after aspirating any effusion was investigated and averaged 6.8 ml, being independent of the presence of a lesion. Because it causes dilution of the contrast medium, it is suggested that small amounts of a relatively high-concentrated non-ionic contrast agent should be preferred for double-contrast knee arthrography.

Rheumatoid arthritis of the cricoarytenoid joints: a case of laryngeal obstruction due to acute and chronic joint changes.

A 63-year-old female with severe rheumatoid arthritis and respiratory obstruction with stridor due to cricoarytenoid (c.a.) arthritis is described.

A method for assessing the height of the patella.

In 150 normal subjects the distance (P) between the upper and lower limits of the articular surface of the patella, and the shortest distance (T) between this same lower limit and the tibial plateau, were measured in standard lateral views of the knee in about 30 degrees of flexion. The limits of confidence of the T/P ratio are shown in the Table. The 5% upper limit of normality of this ratio is 1.

Sclerotic changes of the sternal end of the clavicle.

Five adult females with swelling, tenderness and similar sclerotic changes of the sternal end of the clavicle are presented. They were recognised during a 10-year period, suggesting that the condition is rare and may be misdiagnosed. In three patients strain of the sternoclavicular joint seemed to be an aetiological factor.

Monarticular involvement of the manubriosternal joint.

Four females and two males with seronegative monoarthritis of the manubriosternal joint are reported. Two patients had pustulosis palmoplantaris, one psoriasis vulgaris, and one HLA-B27. The arthritis is considered to be a monoarticular manifestation of seronegative spondylarthritis.

Persistent transverse articulation of the sternal body with monarthritis.

Monarthritis of the manubriosternal joint is a known but uncommon disease. A case is presented with the tissue type HLA-B27 and monarthritis of a persistent transverse articulation of the sternal body. To our knowledge this is a unique case, but with the same etiology as similar changes of the manubrio-sternal joint.

Sclerotic changes of the manubrium sterni.

Six females with nearly identical sclerotic and hyperostotic changes of the manubrium sterni are reported. Malignancies, bacterial inflammatory processes, and Paget disease, which were first suspected, could be excluded. The youngest patients also had sclerotic changes of other bones, including the lumbar spine, the pubic bone, and the clavicle, and may be classified as having "chronic recurrent multifocal osteomyelitis" (CRMO).

Atrioventricular conduction time in rheumatoid arthritis.

The atrioventricular conduction time (P-R interval) was determined in 189 women and 90 men with rheumatoid arthritis (RA). Only three women and one man were found to have pathological prolongation of the P-R interval. However, a significant prolongation of the P-R interval, within normal range, was seen in women with RA compared with healthy controls.

Rheumatoid arthritis of the crico-arytenoid and crico-thyroid joints: a radiological and clinical study.

Low-voltage neck radiography and indirect laryngoscopy was performed in 22 randomly selected rheumatoid patients with the purpose of detecting intralaryngeal arthritis. Radiographic evidence of erosive arthritis of the crico-arytenoid (CA) joints was found in 45% of the patients. Clinical acute CA arthritis without erosive changes was present in two patients, the overall incidence of CA arthritis being 55%.

Computed tomography of the knee with reference to meniscal tears. A preliminary report.

CT scanning of the knee was performed in one patient with a Baker's cyst and normal menisci and 8 patients with meniscal tears diagnosed at arthrography and confirmed at arthrotomy. The normal menisci were clearly demonstrated. The torn parts of the menisci invariably had ill-defined free edges and contained areas of low CT attenuation.

Ossification and calcification of the laryngeal skeleton.

Low voltage radiography of the neck was performed in 64 patients (48 males, 16 females) aged over 34 years. The degree and frequency of ossification of the thyroid and cricoid cartilage were lower in the females than in the males, especially in the anterior parts of the cartilages. The arytenoids were ossified or calcified in all females and in 94 per cent of the males.

Controlled release indomethacin (Indotard). Clinical trial in patients with rheumatoid arthritis.

In a double-blind, crossover multicentre trial the effect on morning stiffness and occurrence of side effects of a controlled-release indomethacin preparation, Indotard, was compared with a conventional preparation, Indocid. 30 Patients between 38 and 74 years of age--six from each centre--underwent the investigation: A 4-day escalating period and 2 X 7 days' treatment. In the average figures, no difference in effect or side effects could be seen between Indotard 50 mg given twice and Indocid 25 mg given four times daily.

Prevalence of cardiac and aortic enlargement in rheumatoid arthritis and its relationship to some characteristics of the patients. A radiological and clinical study.

The chest radiographs of 309 patients with rheumatoid arthritis (RA) were compared with those of 309 controls matched for sex and age. Cardiac enlargement was more frequent in RA females than in controls (P less than 0.05) and the frequency of aortic shadow enlargement was higher in RA patients aged greater than or equal to 60 years than in controls (P less than 0.

Pleurisy in rheumatoid arthritis.

In 157 women and 77 men with rheumatoid arthritis, observed for a mean of 5.7 years, the annual incidence of pleural effusion was found to be 0.34% in the women and 1.

Visualisation of the intralaryngeal joints: a low voltage radiological study.

Low-voltage radiography of the neck was adjusted for visualisation of the crico-arytenoid joints. Sixty-four patients (48 males, 16 females) with laryngeal tumours were examined. The degree of ossification in the laryngeal cartilage around the crico-arytenoid joints was different in the males and the females.

Prevalence of pulmonary involvement in rheumatoid arthritis and its relationship to some characteristics of the patients. A radiological and clinical study.

The chest radiographs of 309 patients with rheumatoid arthritis (RA) were compared with those of 309 controls. In RA, lung nodules were present in 0.3% and pleural effusion in 0.
