OBJECTIVES: This study evaluates the change of the left atrial appendage function before and after electrical cardioversion to understand the mechanism involved in systemic thromboembolism of atrial fibrillation. BACKGROUND: Systemic thromboembolism associated with electrical cardioversion of atrial fibrillation is thought to originate from the left atrium or left atrial appendage, or both.However, the mechanism involved is poorly understood. METHOD: We studied left atrial appendage function funcction with transesophageal echocardiography in 15 patients with atrial fibrillation before and after successful electrical cardioversion. We measured left atrial appendage emptying and filling velocities and left atrial appendage areas. Also we analysed the characteristic Dopper flow pattern of LAA. RESULT: Left atrial appendage emptying velocities before cardioversion were greater in patients without(32.0+/-13.2cm/sec) than in those with(21.4+/-7.6cm/sec) spontaneous echo contrast(SEC). Furthermore emptying velocities after cardioversion were significantly reduced group with (21.4+/-7.6 vs 12.2+/-9.6, p<0.05) and the groupwithout(32.0+/-13.2 vs 18.1+/-10.2, p<0.05)SEC. CONCLUSION: After electrical cardioversion for atrial fibrillation left atrial appendage function is impaired. These observations suggest that stunned left atrial appendage after cardioversion may predispose to thrombus formation, which may play a role in the mechanism involved in the occurrence of thromboembolism after cardioversion.

Total knee arthroplaty has been used to treat the elderly patient who has severe arthritis but the early designs were associated with many problems, which frequently led to early failure. In 1974, the total knee arthroplasty was introduced and the reported results of this operation have improved consistantly with time. Recently the good results has been shown to treat rheumatoid patients and osteoarthritis patients less than 45 years old patients. At the department of orthopaedic surgery of Kosin Medical College, between 1984 and 1988, total knee arthroplasty was performed in 17 patients (22 kness) who had rhematioid arthritis (7 patients) and osteoarthritis (11 patients), and had followed for an average of 1 year and 8 months. The results were as follows 1. The knee that had rheumatoid arthritis had better knee scores than that of osteoarthritis. 2. The knee that remained the post cruciate lig. had better range of motion than that sacrificed. 3. The knees that had not used cement had better knee scores than that had used the cement. 4. The knees that had patella resulrfacing had better scores for pain than that had not.

PURPOSE: We evaluated the capability of MR in the diagnosis of anomalous pulmonary venous connection (APVC). MATERIALS AND METHODS: The patient group consisted of 11 total APVC and 8 partial APVC diagnosed with MR. Echocardiography was performed in all cases, cardiac angiography in 12 cases and operation in 12 cases. We compared MR findings with those of operation, echocard iography and cardiac angiography. RESULTS: In surgically proven 12 cases, diagnostic accuracy of preoperative MR, echocardiography and cardiac angiography was 100%, 67% and 63%, respectively. In the remaining cases, MR findings well correlated with those of echocardiography or cardiac angiography. Stenosis of common pulmonary vein or superior vena cava was identified in 4 cases. In one patient, MR depicted associated cor triatriatum clearly. CONCLUSION: MR is an effective modallty in depicting anomalous pulmonary venous con nections.

Malignancy may cause variable musculoskeletal symptoms which resemble connective tissue disorder. This symptoms as a fine sign of hidden neoplasm can precede the diagnosis of underlying malignancy. But only one case of stomach cancer associated with cancer arthritis was reported in the world. This fact is very interesting in Asia which has high prevalence of stomach cancer. We experienced one case of gastric adenocarcinoma with oligoarthritis involving both knee and right elbow. A 48-year-old man was diagnosed stomach cancer by gastric endoscope and biopsy. After then, he complained pain, tenderness, heating sensation, swelling of both knee and right elbow with high fever. Both knee MRI showed abundant synovial effusion and soft tissue edema. Full dose of nonsteroidal anti-inflammatory drug was not effective to control fever and arthritis. But fever and arthritis were gone after resection of tumor.

A study was done to evaluate the diagnostic value of ultrasonography on acute scrotum patients. During the last three years, 25 patients were managed at Cheju Medical Center, eight of them were testicular torsion patients including one cryptorchid testicular torsion. one torsion of appendix testis, 11 acute epididymitis and 5 testicular rupture due to blunt scrotal trauma. Ultrasonography revealed enlarged testis and epididymis in all of the 8 testicular torsion patients and 7 of them showed inhomogeneously decreased echogenecity of the testis and epididymis. All acute epididymitis patients showed enlargement of the epididymis, and inhomogeneously decreased echogenecity was found in 8 of them. But testicular echogenecity was normal in all of the acute epididymitis patients and enlargement of the testis was found in two. All of the 5 testicular rupture patients showed irregular hypoechoic portions in the testicle and distorted testicular morphology, and linear fracture lines of the testis were found in two. We could suggest that scrotal ultrasonography is useful for the early differential diagnosis of the acute scrotum, especially when scrotal radioisotope scan is not available.

Percutaneous transluminal angioplasty(PTA) were performed in three patients with atherosclerotic stenosis of subclavian arteries. The arteries were successfully dilated without complications during the procedure. All patients were asymptomatic during follow-up periods ranging from eight months to fifteen months after PTA.
