We report the implantation of a balloon-expandable intravascular stent at proximal left anterior decending artery in a patients suffered from Canakian functional class III angina for 8 years. The patient received 3 times percutaneous transluminal coronary angioplasty at proximal left anterior descending and circumflex artery without benefits. Repeated angiography revealed restenosis at proximal left anterior descending artery. Atherectomy was tried with transluminal extraction catheter(TEC) with luminal dissection and coronary bypass graft followed. occluded vein grafts were defined by follow-up angiography and chest pain recurred. No residual stenosis or thrombosis was documented in 24 hour follow-up angiography and the patient was discharged without symptom at 10 days after stenting.

3.Diagnostic Challenge of Hemorrhagic Fever with Renal Syndrome on Admission before its Serological Confirmation.
Korean Journal of Nephrology 2004;23(1):82-91
PURPOSE: The purpose of this study was to look for possible changes from typical clinical features of 5 sequential clinical phases described in 1950s. METHODS: The clinical features and laboratory data of hemorrhagic fever with renal syndrome (HFRS) with acute renal failure (ARF) and its subdivided 2 groups of correct and incorrect impression of HFRS on admission before the serological confirmation were reevaluated in 35 patients admitted at a single tertiary center from 1995 to 2000. RESULTS: We experienced the high failure rate (74%, 26/35) to recognize HFRS as the cause of ARF on admission. On admission, fever was present in all patients (100 %), and thirty three (94%) had either single or combined gastrointestinal symptoms. However, no one had clinical shock and only 4 patients (11%) had hypotension. Also, oliguria was noted only in 5 patients (14%) during the first 24 hrs on admission. When compared between 2 groups of correct (n=9) and incorrect impression of HFRS (n=26), febrile (100% vs 100%) and gastrointestinal symptoms (89% vs 96%) were present high both but hematologic (67% vs 23%) and hemodynamic signs (67% vs 4%) were much less present in the latter. The patients of incorrect impression on admission were admitted more than half (14/26, 54%) under non-renal care, and were exposed to antibiotics (46%) and even steroids (15%), respectively. In addition, these patients with incorrect impression on admission showed the unwanted outcomes of longer hospitalization than those with correct impression of HFRS (mean+/-SD, 21+/-3 vs. 12+/-4 days, p<0.01). CONCLUSION: Its well awareness of the changing clinical features in endemic area of HFRS would avoid overlooking Hantaviruses as a causal agent of ARF on the initial admission stage of HFRS leading to unnecessary treatments and longer hospitalization.

PURPOSE: To evaluate the clinical results of short duration photodynamic therapy (PDT) using verteporfin in patients with chronic central serous chorioretinopathy (CSC). METHODS: We retrospectively examined 15 eyes after PDT for chronic central serous chorioretinopathy. PDT for 83 seconds was evaluated for 8 eyes, and PDT for 60 seconds was evaluated for 7 eyes. Improvement in vision and changes in central macular thickness were evaluated with an optical coherence tomogram (OCT), and improvement in leaking was evaluated with a fluorescein angiogram (FA). Recurrence was also studied. RESULTS: Visual acuity improved from 0.39 to 0.57 (p=0.04), and the mean central macular thickness decreased from 426.29 micrometer to 184.71 micrometer (p<0.01) in 7 eyes treated with PDT for 60 seconds. There was no significant change in visual acuity between the two groups (p=0.77) or in central macular thickness (p=0.52). Central macular exudation resolved completely in all eyes. After PDT, there was no recurrence during the follow-up period. CONCLUSIONS: Short duration PDT with verteporfin appears to be a beneficial treatment option for patients with chronic CSC.

9.Metabolic Acidosis in Maintenance Hemodialysis Patients: Clinical Impact and Intervention.
Electrolytes & Blood Pressure 2007;5(1):42-46
Metabolic acidosis has been considered as one of the reverse epidemiologic factors for the morbidity and mortality in maintenance hemodialysis patients (MHP). Expectedly, in the recent large scale epidemiologic study (The Dialysis Outcome Practice Pattern Study, DOPPS), a mild to moderate degree of predialysis metabolic acidosis has shown better nutritional status and lower relative risk for mortality and hospitalization in MHP. Similarly, another recent study of the largest sample size of MHP of more than 55,000 revealed the lowest unadjusted mortality with mild to moderate degree of predialysis HCO3 levels (17 to 23 mEq/L). However, it was reversed after case-mix and multivariate adjustment, including the malnutrition-inflammation complex syndrome, so that predialysis HCO3 levels of more than 22 mEq/L had a lower death risk. On view of this up-to-date on-going controversy about the optimal acid-base status for MHP, this paper will review the historical and break-through data about the pros and cons of metabolic acidosis published in the clinical human studies of MHP, a special subgroup of chronic kidney disease patients. Based on these results, if possible, we would like to suggest the best practice guideline, particularly, for the optimal predialysis HCO3 level, dialysate HCO3 concentration, and dietary protein intake.

PURPOSE: The purpose of the present study is to determine the relation between in vitro resistance to 9 drugs, measured with colorimetric methylthiazol tetrazolium(MTT) assay and prognostic factors. METHODS: Thirty children with leukemia were evaluated at the pediatric department of Dongsan Medical Center. All samples tested with the MTT assay contained 80% or more leukemic cells, which were isolated by Ficoll density gradient centrifugation, and were incubated with 9 drugs for 4 days. The optical density(OD) of the wells was measured with microplate spectrophotometer. Leukemic cell survival(LCS) was calculated by OD treated well/OD control wellsx100(%). LD50 was calculated from the dose-response curve and used as a measure of resistance. RESULTS: Among the 30 children with leukemia, 16 were ALL, 14 were AML. Seventeen boys and thirteen girls ranged in age from 9 months to 16 years. Comparing LD50 values according to leukemic type, AML revealed relatively high LD50 values for all drugs, except VCR. But there were no significant differences between ALL and AML(P>0.05). Male showed high LD50 values for ASP, DET, ARA-C, VP16, ADR and 6TG. Age<2 and >10 years children showed high LD50 values for all drugs, except 6TG. Patients with a leukocyte count>100,000/mm3 at diagnosis showed high LD50 values for VCR, ASP, DET, MTX, ARA-C, ADR, and 6TG. Patients with normal chromosome showed higher LD50 values. CONCLUSION: Our study showed higher LD50 values at AML, male, age<2 and 10>years old, leukocyte count>100,000/mm3, and normal karyotype. The MTT test may contribute to the selection of effective chemotherapeutic agent for children with acute leukemia.
