A persistent left superior vena cava is the most common anomaly of the superior caval system. Usually the persistent left superior vena cava is connected with the right atrium via the coronary sinus, resulting in no physiologic derangement : however in 7 to 8 percents of the patietns with a persistent left superior vena cava, the anomalous vessel communicates with the left atrim. In the absence of obstruction to the flow from the left atrium to the left ventricle. this anatomic situation usually results in right to left shunting of varying degress. We recently experienced a case of persistent left superior vena cava in a 52-year-old female who complained of chest discomfort, epigastric pain and dyspnea(NYHA functional class II). Cine-angiography showed that the contrast passed from the left SVC through the dilated coronary sinus into right atrium. And right sided SVC was not seen. The patient was treated with conservative measures and discharged with improved condition.

PURPOSE: The nuclear factor-kappa B (NF-kappa B) has been known to regulate the inflammatory and immune process by transcription of inflammatory intermediates. The purpose of the present study is to show the difference in activity of NF-kappa B and its inhibitory factor-I kappa B alpha in patients with rheumatoid arthritis, osteoarthritis and normal control subjects. MATERIALS AND METHODS: Synovial membrane samples were obtained at the time of orthopedic surgery from the knees of 7 patients with RA and 7 patients with OA. Two control samples were obtained from an amputee with no history of arthritis. We designed the primer of the subunit p65 of NF-kappa B and I kappa B alpha, measured the activity of them by RT-PCR, and analyzed the expression of NF-kappa B by immunohistochemical staining. RESULTS: From the results of RT-PCR, the expression levels of NF-kappa B was found to be higher in synovial tissues obtained from patients with RA than from synovial tissue obtained from patients with OA, and the least from the control group. The expression levels of I kappa B alpha were not different statistically among the three groups. Immunohistochemical staining for the NF-kappa B was dominant in synovial tissue from patients with RA. The result of immunohistochemical staining was similar to the results of RT-PCR for NF-kappa B. The localization of the staining was predominantly nuclear. CONCLUSION: In this study, activity of NF-kappa B of rheumatoid arthritis was higher than the other group, but expressions of I kappa B alpha were no different between the diseases. Further studies about specific inhibitors of NF-kappa B will benefit the development of rheumatoid arthritis regimens with greater efficacy.

BACKGROUND: Acute left main coronary artery occlusion is a dramatic condition with very high mortality. The study was aimed to evaluate the effect of primary stenting in patients with left main coronary artery disease in the setting of acute myocardial infarction. METHODS: Between June 1997 and April 2002, primary stenting for left main coronary artery disease was performed in eighteen patients with acute myocardial infarction. We evaluated clinical outcomes and prognostic determinants in this clinical setting. RESULTS: Mean ages of patients were 59 +/- 12 years. Fourteen patients had cardiogenic shock on admission. Angiographic success (TIMI flow >or= 2 and diameter stenosis < 30% after stenting) was achieved in 17 patients (94%). In-hospital death occurred in 8 patients (44%). Two patients (11%) received emergent bypass surgery because of hemodynamic instability after primary stenting. On univariate analysis, good pre-intervention TIMI flow (grade >or= 2) was identified as a good prognostic determinant of in-hospital survival. During mean follow-up of 39 +/- 22 months, there was no late death and 1 patient received bypass surgery. Probability of freedom from death at 3-year was 56 +/- 12%. CONCLUSION: Primary stenting is a valuable therapeutic strategy for left main coronary disease in the setting of acute myocardial infarction, and it might save the life especially in patients with good pre-intervention TIMI flow (grade >or= 2). Long-term clinical outcome of patients surviving to hospital discharge is favorable.

PURPOSE: The main treatment for stage IV breast cancer is currently systemic therapy. Surgical resection of the primary tumor is usually done for treating the tumor-related complications. Recent studies have suggested that surgery may improve the long-term survival of stage IV breast cancer patients. We evaluated the impact of the primary surgical resection site on the survival of stage IV breast cancer patients. METHODS: We reviewed the records of the stage IV breast cancer patients who were treated at Seoul University Hospital between April 1992 and December 2007. The tumor and clinical characteristics, the type of treatments and the overall survival were compared between the surgically versus nonsurgically treated patients. RESULTS: Of the 198 identified patients, 110 (55.8%) received surgical excision of their primary tumor and 88 (44.2%) did not. The mean survival was 67 months vs. 42 months for the surgically treated patients vs. the patients without surgery, respectively (p=0.0287). On a multivariate analysis with using the Cox model and after adjusting for the estrogen receptor status, visceral metastases, the number of metastatic sites and trastuzumab treatment, surgery was an independent factor for improved survival (hazard ratio, 0.55; 95% confidence interval, 0.31-0.97; p=0.041). CONCLUSION: Surgical resection of the primary tumor in stage IV breast cancer patients was independently associated with improved survival. Randomized prospective trials are needed to firmly recommend surgical resection of the primary tumor in stage IV breast cancer patients.

PURPOSE: A newly isolated mediastinal lymph node (LN) or a small pulmonary nodule, which appears during breast cancer surveillance, may pose a diagnostic dilemma with regard to malignancy. We conducted this study to determine which clinical factors were useful for the differentiation of malignant lesions from benign lesions under these circumstances. MATERIALS AND METHODS: We enrolled breast cancer patients who were presented with a new isolated mediastinal LN or small pulmonary nodule that arose during surveillance, and whose lesions were pathologically confirmed. Tissue diagnosis was made by mediastinoscopy, video-assisted thoracic surgery or thoracotomy. RESULTS: A total of 43 patients were enrolled (mediastinal LN, 13 patients; pulmonary nodule, 30 patients). Eighteen patients (41.9%) were pathologically confirmed to have a benign lesion (benign group), and 25 patients (58.1%) were confirmed to have malignant lesion (malignant group). Between the two groups, the initial tumor size (p=0.096) and N stage (p=0.749) were similar. Hormone receptor negativity was more prevalent in the malignant group (59.1% vs. 40.9%, p=0.048). The mean lesion size was larger in the malignant group than in the benign group (20.8 mm vs. 14.4 mm, p=0.024). Metastatic lesions had a significantly higher value of maximal standardized uptake (mSUV) than that of benign lesions (6.4 vs. 3.4, p=0.021). CONCLUSION: Hormone receptor status, lesion size, and mSUV on positron emission tomography are helpful in the differentiation of malignant lesions from benign lesions in breast cancer patients who were presented with a new isolated mediastinal LN or small pulmonary nodule during surveillance.

Obstructive intracardiac lesions, like mitral stenosis or insufficiency (MR), by myxomas of the left atrium have been commonly reported, but the attenuation of MR by myxoma combined with coronary artery disease is very rare. We report a 70-year-old female patient whose left atrial myxoma had attenuated moderate MR to mild MR and required mitral valve surgery after removal of the myxoma. She also had coronary artery disease, severe pulmonary hypertension and moderate tricuspid regurgitation due to the mitral valve lesions obstructed by myxoma. The patient underwent removal of myxoma, mitral and tricuspid valve reconstructions, and coronary artery bypass grafting. She was discharged at the postoperative 14 day without any problems.

BACKGROUND: Mitral valve repair rather than replacement for mitral regurgitation (MR) offers a number of well-accepted benefits. However, the surgical results of repair for mitral valve endocarditis remain largely unknown. MATERIAL AND METHOD: Fourteen patients who underwent mitral valve repair for MR caused by mitral valve endocarditis from April 1995 through October 2001 were reviewed retrospectively. There were 9 male patients and mean age was 32+/-10 years. Four patients had previous embolism and 2 had active infections. The grade of MR were III in 6 patients and IV in 8. Operatively, mitral annuloplasty was performed in 12 patients and various valvuloplasty techniques were applied in all patients. One patient had immediate valve replacement due to residual MR after weaning of cardiopulmonary bypass. RESULT: There was no early operative death. Early postoperative transthoracic echocardiography revealed no or grade I of MR and no or mild mitral stenosis in 13 patients. After the mean follow-up of 36 months, there was no late death, and no or grade I of MR in 11 patients (84.6%) and no or mild mitral stenosis in 12 patients (92.3%). Reoperation required in one patient (7.1%). The cumulative freedom from recurrent MR and valve-related reoperation at 5 years were 91+/-9% and 75+/-22%, respectively. CONCLUSION: This study suggests that mitral valve repair for mitral regurgitation caused by endocarditis offers good early and intermediate survival and functional improvement without reinfection, and it is an attractive alternative to valve replacement in selective patients with bacterial endocariditis.

BACKGROUND: Left ventricular dysfunction is one of the important prognostic factors of early mortality and long-term survival after valve operation. We studied the intermediate term results of mitral valve reconstruction in patients with moderate to severe left ventricular dysfunction. MATERIAL AND METHOD: Forty four patients who underwent mitral valve reconstruction with a left ventricular ejection fraction (EF) of <45% or less (20~45%) from April 1995 through July 2001 were reviewed retrospectively. Ages ranged from 10 to 67 years (46+/-14 years) and 32 patients were in NYHA class III-IV. The mitral valve diseases were regurgitation (MR) in 28 patients, stenosis(MS) in 10, and mixed lesion in 5. The etiologies of mitral valve disease were rheumatic in 20 patients, degenerative in 14, ischemic in 5, annular dilatation in 2, congenital in 2, and endocarditis in 1. Operatively, all patients had annuloplasty and/or various valvuloplasty techniques, and a total of 52 procedures were concomitantly performed. Total cardiopulmonary bypass and aortic crossclamp time were 160+/-57 minutes and 112+/-45 minutes respectively. RESULT: Two operative deaths occurred as a result of left ventricular failure (4.5%). After the mean follow-up of 39 months (range, 10~83 months), there was no late death. Transthoracic echocardiography revealed no or grade I of MR in 29 patients (72.5%) and no or mild MS in 35 patients (87.5%). The actuarial survival at 5 years was 100%. Four patients required mitral valve replacement due to progressive mitral valvular disease. The actuarial freedom from valve-related reoperation at 5 years was 84+/-9%. CONCLUSION: This study suggests that mitral valve reconstruction in patients with moderate to severe left ventricular dysfunction offers good early and intermediate survival and acceptable freedom from valve-related reoperation, and it is the strategy for effective management for these patients.

Melioidosis is an infection of the Gram-negative bacterium Burkholderia pseudomallei. While it is known as an important cause of sepsis or chronic abscessforming disease in Southeast Asia and northern Australia, no case has yet been reported in Korea. A 50-yr-old man visited our hospital for intermittent fever associated with dry cough and sputum. Roentgenographic examination showed migrating pulmonary infiltration. Symptoms and chest radiograph and computed tomography (CT) image findings did not improve despite use of fluoroquinolone antibiotics. Gram-negative bacteria were isolated on bronchoscopic washing culture and were identified as B. pseudomallei on DNA sequencing of 16S ribosomal RNA with 100% homology. Treatment for melioidosis was commenced with high dose ceftazidime, and the patient's fever, cough, and sputum were improved and the lesion on chest radiograph and CT almost disappeared.
