BACKGROUND: Atrial fibrillation (AF) is one of the most common clinical arrhythmia. AF may cause disabling symptoms and serious adverse effects, such as impairment of cardiac function or thromboembolic events. Until now, there were no study about the clinical characteristics of atrial fibrillation throughout this nations. The purpose of this study is a establishment of epidemiologic database of patients with atrial fibrillation in this nations. METHODS: 867 patients from 12 university hospitals were involved in this study. Atrial fibrillation were diagnosed with documented ECG in all patients. Medical history, physical findings, basic Laboratory finding, ECG, echocardiography and 24-hour Holter monitoring of these patients were evaluated. Chronic atrial fibrillation were defined as the duration of AF longer than 72 hours regardless of intervention. RESULTS: In patients with chronic atrial fibrillation, the most common symptom was dyspnea and the most common associated diseases were valvular heart disease, hypertension and ischemic heart disease. 2) In patients with paroxysmal atrial fibrillation, the most common symptoms were palpitation, dizziness and chest pain, and the most common associated diseases were hypertension, ischemic heart disease and valvular heart disease. 3) left atrial size, systolic and diastolic left ventricular size in patients with chronic atrial fibrillation were significantly increased as compared those in patients with paroxysmal atrial fibrillation (p<0.001). 4) cardiomegaly and pulmonary edema were more common in patients with chronic atrial fibrillation (p<0.0001). CONCLUSIONS: This study is first large multicenter study about atrial fibrillation in this nations. These data can be used as basic data for follow up and management of atrial fibrillation.

CT findings of 19 kidneys in 12 patients with renal and perirenal non-Hodgkin's lymphoma were retrospectively reviewed to determine distinguishing characteristic and specific findings. CT manifestation of the renal and perirenal lymphoma included multiple nodules in five kidneys(26.3%), trans-capsular infiltration in three kidneys(15.8%). trans-sinus infiltration in nine kidneys(47.4%) and diffuse infiltration in two kidneys(10.5%0. Perirenal changes were thickening of the renal fascia in ten kidneys(52.6%) and crescentic lesion of low attenuation in the subcapsular area in five kidney(26.3%). Retroperitoneal lymphadenopathy was evident in eleven patient(57.9%). Renal calyceal dilatation without renal pelvic dilatation(selective calcelal dilatation) was noted in three kidneys. Familiarity with these CT findings of renal and perirenal lymphoma may be helpful in the diagnosis and management of patient with non-Hodgkin's lymphoma.

Adenocarcionma of fetal type is in lung is a newly recognized malignant tumor sharing morphologic features with the epithelial component of the pulmonary blastoma devoid of sarcomatous component. We present a case of adenocarcinoma of fetal type in a 28-year-old female, consisting of numerous branching tubules or glands and morula-like epithelial complexes. Histologically, the tubules and glands were composed of glycogne-rich nonciliated epithelial cells showing in part argyrophilia. Some of tubular and morula-like epithelial cells revealed immunoreactivity for neuron-specific enolase. We report this case with a review of literatures with special references on the histogenisis. This report is the pathologically confirmed second case of the pulmonary adenocarcinoma of fetal type in Korea, following the report of Cho and Lee, 1990.

The authors report a case of uterine tumor resembling ovarian sex-cord tumor in a 31-year-old woman with emphasis on immunohistochemistry. Histologically this case showed identical features to a well-recognized endometial stromal tumor except for focal epithelial-like differentiation that resembled sex-cord tumors of the ovary. The sex-cord like differentiation of tumor cells were manifested by trabeculae, plexiform cords, and gland-like pattern. We diagnosed this case, according to the features described by Clement and Scully(1976), as uterine tumor resembling ovarian sex-cord tumor, group I. Although the histogenesis of this tumor is unclarified, most authors believe that this tumor may be originated from multipotent mesenchymal cells of the uterus. On immunohistochemical stains, Desmin was uniformly reactive in epithelial-like cells and in focal areas of endometrial stromal sarcoma-like component. Vimentin was partly reactive in all tumor components, however EMA was non-reactive.

A 52-year-old woman with esential mixed cryoglobulinemia (type II ), which was confirmed by cryoglobulin elcct,rophoresis and immunofixation elect,rophoresis, had purpuric skin lesions on the legs. The lesions had a tendency of recurrence for the past 2 years, and moderate degrees of arthralgia and myalgia were accompanied in each time. However, the patient had not been suffered from any internal organ distress caused by the disease proress. Histological examinations of a skin lesions revealed a feature of leukocytoclatic vasculitis, and deposits of IgM, IgG and C; were also recognized. A regimen of small doses of prednisolone was effective for the cutaneous lesions in this patient for 4 months follow-up until this writing. It, seems that the patient has had a mild form of the disease among the clinical spectrum of mixed cryoglobulinemia, with a cryocrit value of 2.4% at the time of her initial visit..
