We report the case of a 42-year-old male who was admitted to the hospital with progressive dyspnea. Cardiomegaly and diffuse pulmonary edema were visible on chest X-ray and multiple oral and genital ulcers on physical examination. On admission, echocardiography revealed mitral valve prolapse (MVP) predominantly involving a basal portion of the posterior leaflet, with severe mitral regurgitation. A successful mitral valve replacement with St. Jude #29 was performed, after pre-treatment with prednisolone for 2 weeks. Fifteen months following the operation, the patient expired from severe pulmonary edema and secondary pneumonia. This case demonstrates, for the first time in the literature, an unusual feature of mitral prolapse in the basal portion with severe mitral regurgitation in a patient with Behcet's disease. As suggested by this case, we should consider an atypical type of MVP as a possible inflammatory involvement of the heart in patients with Behcet's disease.

Coarctation of aorta is a rare cause of secondary hypertension, and premature death will occur if no appropriate treatment is given. The only effective treatment was surgery before 1980, but restenosis was frequent. Several works on percutaneous transluminal angioplasty of the disease were reported. In patients with previously operated recoarctation, there is no doubt that balloon angioplasty is now the first choice of the therapy because of the surgical risks of reoperation. Nevertheless, there has still been some controversy regarding the application of this therapy to native coarctation, because of the potential risk of aortic disruption and the high incidence of restenosis. There have been some clinical reports of successful stent implantation for coarctation without major complications since 1991. We report on our experience with balloon-expandable stent implantation for native coarctation of the aorta in a 23-year-old man with congenital mitral stenosis. Aortogram showed a coarcted aortic segment of 3 mm in diameter and 25 mm long just distal to the left subclavian artery. The peak systolic pressure gradient across the coarctation before stent implantation was 100 mmHg. Stent implantation was performed with 14 X 40 mm balloon with Palmaz P308 stent. The peak systolic pressure gradient decreased to zero and the diameter of the coarctation of aorta increased to 14 mm after stent implantation immediately. The patient tolerated well and no significant complications were encountered during the procedure.

BACKGROUND AND OBJECTIVES: Intracardiac pathology results in 15 - 20% of ischemic stroke, but transthoracic echocardiography (TTE) has a number of limitations because of suboptimal precordial windows or ultrasound interference with prosthetic materials. Transesophageal echocardiography (TEE) provides superior resolution of basal structures such as the left atrium, left atrial appendage, mitral valvular apparatus, atrial septum, and aorta. The purpose of this study was to describe the various TEE findings which were sources of cerebral emboli. MATERIALS AND METHOD: The study population was comprised of 122 patients (mean age:54.5, male 83, female 39) who were admitted to Severance Hospital because of ischemic stroke from 1991 to 1997. All patients underwent TEE with agitated saline contrast administration. Patients without a definitive cardiac source of embolism underwent Holtor monitoring, internal carotid and cerebral angiography, as well as transcranial Doppler. RESULTS: 1) The number of patients diagnosed as cardioembolic stroke was 55 (45.1%). Atrial fibrillation was noted in 31 patients of cardioembolic stroke and it was the most frequent finding. Among these patients, 16 did not have any other cardiac problem. 2) We were able to find the possible source of embolism in 49 (40.2%) patients with TEE. Among these patients, 12 did not have dysrhythmia or any known previous heart problem. We found spontaneous echo contrast in the left atrium and left atrial appendage in 33 cases. There were 8 patients who had intracardiac thrombus. Among these patients, 6 patients had thrombi in the left atrial appendage, 1 in left atrium and 1 in left ventricular apex. We found patent foramen ovale in 3 cases and atrial aneurysm in 1 case. We found atheromatous plaque and/or thrombi of the aorta in 16 cases, while there were 4 cases where lesions located in the ascending aorta and aortic arch and which were considered as the source of embolism. Small thrombi in the left atrial appendage and left atrium were only detectable with TEE. CONCLUSIONS: We described TEE findings in ischemic stroke patients. And we assert TEE is a useful diagnostic tool in detecting the source of cardioembolic stroke and it may be used as a primary diagnostic tool in patients who are being evaluated for ischemic stroke.

Effective management of rheumatoid arthritis (RA) necessitates the accurate measurement of disease activity using a treat-totarget strategy established as a cornerstone approach. Disease activity assessment tools such as the Disease Activity Score in 28 joints (DAS28), Simplified Disease Activity Index, Clinical Disease Activity Index, and Routine Assessment of Patient Index Data 3 have been internationally validated and recognised. In Korea, the government initiated a quality assessment program mandating routine measurement of DAS28 to ensure high-quality RA management. However, whether the DAS28 is the most suitable disease activity measurement tool in the Korean clinical environment is a topic worth considering. In this review, we comprehensively examined disease activity measurement tools and their performance in the Korean context. We also propose a new strategy for measuring RA disease activity, tailored to the different situations encountered by physicians in routine clinical practice. This review may contribute to the improvement of the quality of care for patients with RA in Korea.

BACKGROUND: Syphilis is an infection caused by Treponema pallidum (T. pallidum), and this disease is increasing in incidence. However, making the diagnosis of syphilis is sometimes still challenging because of the variable clinical and histopathologic findings and there are cases with negative serologic findings, and especially in the setting of HIV infection and immunosuppressive therapy. OBJECTIVE: In this study, we specifically evaluated the number and distribution patterns of T. pallidum in the skin lesions from patients with primary or secondary syphilis. METHODS: orty eight skin biopsy specimens with the clinical and/or serological diagnosis of syphilis were evaluated by immunohistochemistry (IHC) using primary polyclonal antibodies against T. pallidum. RESULTS: Overall, T. pallidum was identified in 45 specimens (94%). The IHC of the 22 specimens from the patients with primary syphilis were all positive (100%). Twenty three (88%) out of 26 specimens from the patients with secondary syphilis showed positive results. T. pallidum was also identified in three patients with negative VDRL. Although the density of T. pallidum was higher in the specimens from the patients with primary syphilis than in those from the patients with secondary syphilis, the differences were not statistically significant (p=0.32). An epitheliotropic pattern was more frequently observed in the specimens from the patients with secondary syphilis (81%) than in those from the patients with primary syphilis (50%) (p=0.01). The density and distribution patterns of T. pallidum didn't show any correlation with the duration of skin lesions or the VDRL titer. CONCLUSION: IHC using a polyclonal antibody against T. pallidum could be an effective method for making the diagnosis of primary and secondary syphilis.

BACKGROUND: Dobutamine echocardiography has been shown to be a valuable tool for determining myocardial viability in both acute and chronic coronary artery disease with left ventricular dysfunction. The purpose of the our study was to identify the role of dobutamine echocardiography in the prediction of improvement of regional left ventricular (LV) dysfunction after revascularization of chronic coronary artery disease. METHODS: Twenty-three patients (mean age 61.2+/-9.0 years;20 men) with chronic LV dysfunction underwent dobuta-mine echocardiography (dobutamine:baseline, 5, 10, 20 microgram/Kg/min) before coronary revascularization (coronary artery bypass graft surgery 16, percutaneous coronary angioplasty 7). The mean LV ejection fraction was 42.9+/-8.8% with ranging from 26% to 58%. Follow-up echocardiography was performed at 2 to 21 months (mean 9.0+/-6.2 months) after revascularization. RESULTS: During dobutamine echocardiography, there was no major complication. Improvement of the dysfunctional myocardium was observed in 12 of 23 patients in dobutamine echocardiography. Among them, 10 patients showed functonal recovery after revascularization. Another 11 patients did not show improvement of dysfunctional myocardium in dobutamine echocardiography, however 3 of them showed functional recovery after revascularization. One hundred fifteen dysfunctional segments were found in 368 segments of 23 patients, and improvement of wall motion abnormality was observed in 46 of 115 segments in dobutamine echocardiography. Among them, 31 segments showed functional recovery after revascularization. Another 69 segments did not show wall motion improvement in dobutamine echocardiography. But among them, 13 segments showed functional recovery after revas-cularization. The sensitivity and specificity of dobutamine echocardiography for the prediction of postoperative improvement of segmental wall motion were 70% and 79%, respectively. The positive and negative predictive value of dobutamine echocardiography were 67% and 81%, respectively. CONCLUSION: In patients with chronic LV dysfunction, dobutamine echocardiography can be used as a predictor of the improvement of dysfunctional segments after revascularization.

BACKGROUND AND OBJECTIVES: The purpose of this study was to evaluate the age-related differences in clinical features, coronary anatomy, risk factors, hospital courses, and long-term prognosis of acute myocardial infarction(AMI) in women. MATERIALS AND METHODS: Total 513 female patients with AMI were divided into 3 groups ; group 1(n=3, 50 years old or less), group 2(n=02, between 51 years and 70 years old), and group 3(n=68, older than 70 years). Clinical follow-up including cardiac events was performed for mean duration of 26 months(1~155 months). Cardiac events include cardiac death, reinfarction, CABG, PTCA, CHF, stroke, and recurrent angina. RESULTS: Minimal lesion(<50% stenosis) in infarct-related artery was more prevalent in group 1 than in group 3(p<0.05). In group 2, the number of low high density lipoprotein(HDL) was significantly more than in group 3(p<0.01). During hospitalization, death and shock were more prevalently observed in group 3 than group 1(p<0.005) and group 2(p<0.001). Group 3 had more heart failures than group 1(p<0.001) and group 2(p<0.001) and group 2 had more heart failures than group 1(p<0.05). The younger age group showed a significantly higher survial rate(7 years : group 1; 76.1%, group 2; 60.6%, group 3; 34.2%, p<0.0001, Log Rank Stat =49.4) and cardiac event-free survival rate(7 years : group 1; 48.4%, group 2; 32.3%, group 3; 16.0%, p<0.0001, Log Rank Stat =37.5) for each 3 comparisons. In Cox proportional harzard analysis, LV systolic function influenced the group 2 survival (odds ratio 3.8, 95% CI 1.7 to 8.3, p<0.005) and the group 3 survival (odds ratio 2.2, 95% CI 1.1 to 4.5, p<0.05). The cardiac event free survival was influenced by age(odds ratio 1.6, 95% CI 1.2 to 2.1, p<0.005) and LV systolic function(odds ratio 1.8, 95% CI 1.3 to 2.5, p<0.001). CONCLUSION: Younger female patients with AMI had a more favorable prognosis compared with older female patients. LV systolic fuction was important as a prognostic factor for long-term survival except younger female AMI patients.

Since endocrine disrupting chemicals (EDCs) may interfere with the endocrine system(s) of our body and have an estrogenicity, we evaluated the effect(s) of bisphenol A (BPA) on the transcriptional levels of altered genes in estrogen receptor (ER)-positive BG-1 ovarian cancer cells by microarray and real-time polymerase-chain reaction. In this study, treatment with 17beta-estradiol (E2) or BPA increased mRNA levels of E2-responsive genes related to apoptosis, cancer and cell cycle, signal transduction and nucleic acid binding etc. In parallel with their microarray data, the mRNA levels of some altered genes including RAB31_MEMBER RAS ONCOGENE FAMILY (U59877), CYCLIN D1 (X59798), CYCLIN-DEPENDENT KINASE 4 (U37022), IGF-BINDING PROTEIN 4 (U20982), and ANTI-MULLERIAN HORMONE (NM_000479) were significantly induced by E2 or BPA in this cell model. These results indicate that BPA in parallel with E2 induced the transcriptional levels of E2-responsive genes in an estrogen receptor (ER)-positive BG-1 cells. In conclusion, these microarray and real-time polymerase-chain reaction results indicate that BPA, a potential weak estrogen, may have estrogenic effect by regulating E2-responsive genes in ER-positive BG-1 cells and BG-1 cells would be the best in vitro model to detect these estrogenic EDCs.
