    Criteria for Judging the Improvement in Subclinical Rheumatic Valvitis
    (CAMBRIDGE UNIV PRESS, 2003) Karaaslan, Sevim ; Demiroren, Saadet; Oran, Bülent; Baysal, Tamer; Başpinar, Osman; Uçar, Canan
    Recent technical improvements in cross-sectional echocardiography have made it possible to detect even mild organic regurgitation of the mitral and aortic valves in patients with acute rheumatic fever. To determine the prevalence and prognosis of subclinical valvitis, we have analyzed 104 patients with acute rheumatic fever referred to our institution. Of 53 patients who had no murmur, 22 of them with polyarthritis, 29 with chorea, and 2 with polyarrhritis and chorea, 23 (43.4%) had subclinical valvitis. Isolated mitral regurgitation was the most common valvar lesion, seen in 82.6% of the patients. Isolated aortic regurgitation was detected in 4.4%, of the cases, and combined mitral and aortic regurgitation in the remaining 13%. During follow-up, the degree of mitral regurgitation improved in 59.1%, decreased in 18.2%, and increased or remained unchanged in 22.7% according to the length of colour jet. According to criterions of velocity, mitral regurgitation improved in 86.4% of the patients, and increased or unchanged in the remaining 13.6%. Mitral regurgitation disappeared completely in 6 of the patients (27.3%) as judged according to both the length of colour jet and the velocity of regurgitation. Aortic regurgitation improved in all the patients with this problem, disappearing completely in two of the four. Based on this experience, we suggest that not only the disappearance of regurgitation, but also improvements in the echocardiographic diagnostic criterions of regurgitation, such as the length of the colour jet less than 1 cm, or velocity less than 2.5 m/s, or indicative of regurgitation that is either intermittent or of short duration, should also be considered as criterions indicating improvement in valvar regurgitation in patients with subclinical rheumatic valvitis.

    Sydenham's chorea: A clinical follow-up of 65 patients
    (SAGE PUBLICATIONS INC, 2007) Demiroren, Kaan; Yavuz, Haluk; Cam, Lokman; Oran, Bulent; Karaaslan, Sevim; Demiroren, Saadet
    Sydenham's chorea, the neurological manifestation of rheumatic fever, is the most common acquired chorea of childhood. In this retrospective study, the authors aim to present the clinical and laboratory findings of 65 Sydenham's chorea patients, followed up in a clinic over less than 7 years. The mean age at the onset of the symptoms was 11.7 +/- 2.6 years (range, 6-17 years). Of the patients, 63% were female and 37% were male (male/female: 1.7/1). Chorea was generalized in 78.5% of the patients, right hemichorea in 12.3%, and left hemichorea 9.2%. There was a history of rheumatic fever in 30.8% of the patients. Echocardiographic study showed cardiac valve involvement in 70.5% of 61 patients. Brain magnetic resonance imaging, which was performed on only 18 patients, was evaluated as normal in all. Electroencephalography was also performed on only 18 patients and showed abnormal waves in 50% of them. Pimozide was mostly the first choice of drug therapy. Nevertheless, drug therapy was not needed in 18.5% of the patients. The recovery period of the first attack of the chorea was I to 6 months in 51.7% of the patients. The recurrence rate was 37.9%. In conclusion, Sydenham's chorea is still an important health problem in Turkey with respect to its morbidity.
