BACKGROUND: Onlay vein patch coronary angioplasty has been known to be an option for coronary artery stenosis in the selective iesions MATERIAL AND METHOD: During the period between July 1997 and August 1999, coronary angioplasty using autologous saphenous vein was done on 16 sites in 14 cases for the stenotic lesion at the bifurcation area and significantly stenosis distal to anastomosis. RESULT: Early patency of the angioplasty site was 85.7% at postoperative day 7. There was no statistically difference in graft patency, operative parameters, and complications compared to conventional anatomosis(p>0.05). CONCLUSIONS: Despite the small number of cases, the patency rate of the coronary patch angioplasty was comparable to the conventional CABG. Coronary artery only patch angioplasty could be performed in highly selected coronary arteries.

BACKGROUND: Early patency of the coronary artery bypass grafting is determined mainly by surgical technique and status of coronary artery. We analyzed the early result, focusing on the relationship between postoperative angiographic findings and the patency rate. MATERIAL AND METHOD: During the period of July 1997- August 1999, 86 cases of CABG were performed and the postoperative coronary artery angiography was done in 76 cases on postoperative day 7 to assess the graft patency. RESULT: Overall graft patency was 90.2% on the angiographic finding. Factors influencing the early graft occlusion were the surgeon's experience, small coronary artery size less than 1.5mm in diameter, coronary arteries related to pre-operative myocardial infarction, and local atheroma at the anastomosis site(p<0.001). Operative mortailty was 2.3%. Early recurrence of the symptom was 19.8% during the follow up period. CONCLUSIONS: We examined the postoperative coronary angiography and found that the surgeon's experience, small coronary artery size less than 1.5mm in diameter, bypass surgery on the coronary arteries related to pre-operative myocardial infarction, and local atheroma at the anastomosis site were the factors for the graft occlusion.

Tracheo-innominate artery fistula is a rare, but it is one of the gravest complications next to tracheostromy. Early recognition and prompt surgical management is mandatory. The patient was a 66 year old women with MCA infarct who maintained tracheostomy for lyear. She had respiratory arrest due to the excessive bleeding through the tracheostomy site. We report an successful experience for control of bleeding by an innominate artery fistula division and primay suture closure under direct digital compression.

PURPOSE: To evaluate the effectiveness of percutaneous catheter drainage in treatment of the lung abscess. MATERIALS AND METHODS: We treated the lung abscesses in 14 patients(12 men, 2 women), who did not respond to medical therapy, by percutaneous catheter drainage under fiuoroscopic or ultrasound guidance. One abscess due to infacted bulla was managed by combination treatment with alcohol sclerosing therapy. Patients were followed by serial chest radiographs every three days and the amount of drained or aspirated pus evaluated. The treatment effect and recurrence were followed by chest PA and lateral chest at one week after removal of drainage catheter. RESULTS: Thirteen patients(93%) recovered clinically and radiologically within 3 days. In 10 patients, drainage catheter could be removed within 2 weeks, and three patients, the catheter was keept longer. Most complications were mild ;vague to moderate chest pain(n=14), mild hemoptysis(n=2), and pneumothorax(n=I). One man who suffered from far advanced pulmonary tuberculosis died of asphyxia caused by massive hemoptysis 16 days after percutaneous drainage. CONCLUSION: Percutaneous catheter drainage is a safe and effective method for treating lung abscess.

PURPOSE: Conventional contrast dacryocystography(C-DCG) has been used mainly for anatomical assessment of the lacrimal drainage apparatus, due to its limited information on the dynamics of the lacrimal system, and thus correlation role in epiphora. The purpose of study was to improve the diagnostic value in epiphora by utilizing RI dacryocystography(RI-DCG) with quantitative criteria. MATERIALS AND METHODS: The patient for RI dacryocystography set erect with the head fixed in front of gamma camera fitted with a standard 6 mm pinhole collimater. Both eyes of 85 patients(170 eyes) were scanned with 99rnTc-pertechnetate followed by conventional dacryocystography. The data from gamma camera were recorded simultaneously on a computer system for subsequent quantitative analysis. RESULTS: In 94 of 96 eyes without epiphora, RI-DCG was correlated with normal C-DCG and % of emptying was at least over 50%. In 58 of 74 eyes with epiphora, RI-DCG was correlated with abnormal C-DCG and % of emptying was at most below 50%. In 16 eyes with functional block, quantitative RI-DCG showed abnormal % of emptying. CONCLUSION: Nuclear DCG with quantitation had higher diagnostic yield in functional block and correlated higher with epiphora. Thus nuclear DCG with quantitation would be a valuable functional test after postprocedures such as dacryocystoplasty.

BACKGROUND: Myocardial cell death after myocardial infarction or reperfusion is classified into necrosis and apoptosis. Bcl-2 protein is a cytoplasmic protein, which inhibits apoptosis and is expressed in acute stage of myocardial infarction but not in normal heart. This study was performed to investigate whether Bcl-2 protein was expressed respectively to the reperfusion time. MATERIALS AND METHODS: Thirty nine New Zealand white rabbits weighing 1.5-4.8 kg (mean, 2.9kg) were alloted into 7 groups (n=5 in each group) which underwent left anterior descending coronary artery (LAD) occlusion for 30 minutes, followed by reperfusion. The animals were sacrificed at 1, 4, 8, 12, 24 hours, and 3, 7 days after occlusion. Ventricle was excised immediately after intervention. Tissues were fixed in 10% buffured formalin and embedded in paraffin. Bcl-2 protein was detected by immunohistochemical stain with using monoclonal antibody against Bcl-2 protein. RESULTS: The positive immunohistochemical reactivity for Bcl-2 protein was observed in 12, 24 hours, and 3 days reperfusion groups. Bcl-2 protein was detected in salvaged myocytes surrounding the infarcted area. CONCLUSIONS: Bcl-2 protein is expressed at the late acute stage of infarct. Therefore, the expression of Bcl-2 protein may not protect acute cell death, but may play a role in the prevention of late cell death after myocardial is chemia-reperfusion.

Endomyocardial fibrosis(EMF) is an unusual type of cardiomyopathy characterized by a restriction to the ventricular filling and an obliteration of the inflow portion in the ventricular cavity by a fibrosis and often by a thrombus formation. The atrioventricular valve may be involved, resulting in an atrioventricular valvular regurgitation. The only known effective treatments are endomyocardiectomy and replacement of regurgitant AV valves. We report the experience of a case of EMF which required surgical management.

Hyperuricemia is associated with metabolic syndrome as well as gout, and the prevalence of hyperuricemia is increasing in Korea. This study aimed to compare the nutrient intake and diet quality between hyperuricemia subjects and controls. Of the 28,589 people who participated in a health examination between 2008 and 2011, 9,010 subjects were selected whose 3-day food records were available. Clinical and laboratory data were collected from electronic medical records. Diet quality was evaluated using the food habit score (FHS), nutrient adequacy ratio (NAR), and mean adequacy ratio (MAR). The prevalence of hyperuricemia was 13.8% (27.1%, men; 5.2%, women). Body mass index, waist circumference, triglycerides, total cholesterol, and low-density lipoprotein cholesterol were significantly higher (p < 0.0001), while high-density cholesterol (p < 0.001) was significantly lower in the hyperuricemia subjects than in the controls. The hyperuricemia subjects had a lower intake of vitamin A (p < 0.004), vitamin C, folate, fiber, and calcium than the controls (p < 0.0001). Intake of vegetables and dairy products was significantly lower, whereas alcohol intake was significantly higher in the hyperuricemia subjects than in the controls ( p < 0.0001). The FHS (p < 0.0001), MAR (p < 0.0001), and NARs for vitamin A (p = 0.01), vitamin B2, vitamin C, folate, and calcium (p < 0.0001) were significantly lower in the hyperuricemia subjects than in the controls. In conclusion, the hyperuricemia subjects reported poorer diet quality than the controls, including higher alcohol intake and lower vegetable and dairy product intake.

BACKGROUND: Autologous peripheral blood-stem cell transplantation (autoPBSCT) is the treatment of choice for hematologic malignancy, because the technique requires neither general anesthesia nor surgical intervention, amongst many other advantages. Despite these benefits, the risk of hematologic malignancy, as well as the effect of patient age and sex on the prediction of successful collection of autoPBSCT are still unclear. The purpose of this study was to examine whether the hematologic diagnosis of the disease, and age or sex affect the mobilization of CD34+ cells and mononuclear cells. METHODS: We retrospectively investigated 30 (6 multiple myeloma, 11 diffuse large B-cell lymphoma, 8 acute myeloid leukemia, 2 acute lymphoid leukemia, and 3 T-cell lymphoma) patients who underwent autoPBSCT between 2008 and 2011 at Daegu Catholic University Hospital. RESULTS: Patients with multiple myeloma had the highest average of both mononuclear cell (MNC) (2.07+/-0.67x10(8) cells/kg) and CD34+ cell (1.28+/-0.58x10(6) cells/kg) counts. Patients with T-cell lymphoma had both the lowest MNC (1.23+/-0.49x10(8) cells/kg) and CD34+ cell (0.20+/-0.6x10(6) cells/kg) counts. Male patients showed greater collected CD34+ cell counts (0.96+/-1.38x10(6) cells/kg) and MNC counts (1.71+/-0.76x10(8) cells/kg) than the female patients. Patients under the age of 44 had higher collected CD34+ cell counts (0.96+/-1.37x10(6) cells/kg) but lower counts of MNC (1.49+/-0.74x10(8) cells/kg). CONCLUSIONS: The collected MNC and CD34+ cell counts varied between the types of malignancies, and with respect to sex and age. However, only collected MNC counts were significantly different (P<0.05) among the different types of malignancies.
