[Recurrent acute idiopathic pericarditis: rheumatologic therapy, autoantibodies and long term outcome]. / Pericardite acuta idiopatica recidivante: terapia reumatologica, autoanticorpi e long term outcome.

OBJECTIVE: To evaluate therapy and rheumatologic aspects of recurrent acute idiopathic pericarditis (RAIP). METHODS: We studied 46 patients. We used non-steroidal anti-inflammatory drugs (NSAIDs) at high dosage. We did not start corticosteroid: if already started, we planned a very slow tapering; 37 patients (80.4%) were treated with colchicine. We also assessed the frequency of ANA, anti-SSA and Rheumatoid factor. RESULTS: With our protocol recurrences dropped from 0.46 to 0.03 attacks/patient/month (p<0.00001) within 12 months and remained at the same level (0.024) till the end of the follow-up (mean 8 years). In the 37 patients treated with colchicine recurrences dropped from 0.5 to 0.03 (p<0.0001) within 12 months, and in 9 patients not given colchicine from 0.27 to 0.045 (p<0.005). When colchicine was used the decrease was significantly higher (0.47 vs 0.23) (p<0.001). In 27 (58.7%) patients ANA were positive at a titre >1/80, in 7 (15.2%) >1/160. Rheumatoid factor was positive in 7 (15.2%) and anti-SSA in 4 (8.7%). During the follow-up 4 (8.7%) new diagnosis of Sjogren and 1 (2.2%) of Rheumatoid Arthritis were made. CONCLUSION: NSAIDs at high dosage, slow tapering of corticosteroid and colchicine are very effective in RAIP. The improvement is more dramatic in colchicine treated patients, but also other patients can achieve good control of the disease. The finding of ANA, anti-SSA and the new rheumatological diagnoses support the involvement of autoimmunity.

[Surgery of the carotid: the morphology of plaque and the clinical correlations]. / Chirurgia della carotide: morfologia della placca e correlazioni cliniche.

A consecutive series of 256 patients operated on of carotid endarterectomy for cerebrovascular atherosclerotic disease from January 1987 through December 1990 is presented. The following parameters were considered: clinical presentation, morphology of the carotid atherosclerotic plaque and topographic distribution of other concomitant atherosclerotic lesions of epiaortic arteries. 422 carotid lesions and 154 lesions of other epiaortic vessels were investigated by means of echo and color flow imaging, digital subtraction angiography and macroscopic observation of the specimen: 143 plaques proved grossly ulcerated. Unilateral lesions were 90 (35.2%) while bilateral disease was present in 166 cases (64.8%): 38.8% of subjects out of the first group and 30.2% out of the second were asymptomatic. Anterior and posterior neurological symptoms were equally distributed among both the 116 (69.8%) symptomatic subjects harboring bilateral lesions and the 55 (61.1%) symptomatic subjects with unilateral lesion (anterior 78.4% and posterior 21.6% for bilateral and 78.2% and 21.8% respectively for unilateral lesions). According to the degree of stenosis, the lesions were divided into three main groups: < 50%; 50-70%; > 70%. As the degree of stenosis increased, the incidence of focal symptoms increased too; moreover, the presence of ulceration of the stenosing plaque carried an increase in the incidence of focal symptoms within each group: respectively from 7.8% to 30% (< 50%), from 18.6% to 53.8% (50-70%), from 27.7% to 55.6% (> 70%). This study supports the relationship of morphological characteristics of the stenosing atherosclerotic plaques of the internal carotid artery to neurological symptomatology.(ABSTRACT TRUNCATED AT 250 WORDS)
