Percutaneous arterial closure devices allow earlier mobilization and discharge of patients after arterial catheterization than manual compression for achieving puncture site hemostasis. Our case is representative of Perclose(r) associated infections; our patient had a delayed presentation of a staphylococcal arterial infection that required arterial debridement and reconstruction. Physicians should be aware of this uncommon, but serious complication to expedite the evaluation and treatment of patients with suspected infections that can arise from using these devices.

Systemic lupus erythematosus (SLE) is a typical autoimmune disease that's characterized by various autoantibodies to nuclear and cytoplasmic antigens. The presence of antinuclear antibodies (ANA) in serum is generally considered a decisive diagnostic sign of SLE. However, a small subset of SLE patients who had the typical clinical features of SLE was reported to show persistently negative ANA tests. Our report describes a 16-yr-old female who presented with the clinical manifestations of SLE such as malar rash, photosensitivity, arthritis, lymphopenia, pericarditis and proteinuria. The serum autoantibodies were all negative and renal biopsy showed that the histopathological changes of immune complex mediated the focal segmental necrotizing glomerulonephritis with crescent formation. She was treated with monthly pulse cyclophosphamide along with corticosteroids. During the 2-yr follow-up period, the proteinuria was markedly decreased and all of the ANA and anti-double stranded DNA antibody tests were negative. This case suggests that ANA may not be required in the pathogenesis of lupus nephritis.

The coexistence of polymyositis and primary biliary cirrhosis is rare. Both are characterized by chronic inflammation and immunological abnormalities. We report a case of 54-year-old female patient presenting with these two autoimmune diseases. She exhibited symmetrical proximal muscle weakness and elevated serum levels of muscle enzymes. Polymyositis was confirmed by electromyography and muscle biopsy. The diagnosis of primary biliary cirrhosis was based on increased serum levels of alkaline phosphatase, IgM immunoglobulin, presence of antimitochodrial antibody and characteristic liver biopy findings. This is the first case who manifest polymyositis and primary biliary cirrhosis simultaneously in Korea.

Spontaneous coronary artery dissection (SCAD) is an extremely rare clinical manifestation of ischemic heart disease. A 43-year-old female was admitted to our hospital for non-ST elevation myocardial infarction. She had no cardiac risk factors except smoking. Coronary angiography showed moderate stenosis of the proximal left circumflex artery (LCX) with intraluminal haziness and a spastic appearance from the culprit lesion in the left main coronary artery (LM). Subsequent analysis by intravascular ultrasound (IVUS) revealed a clear dissection flap from the LCX to the LM. Generally, SCAD of the LM or multivessel involvement requires primary surgical management. The present case was treated percutaneously using the culotte stent technique.

BACKGROUND AND OBJECTIVES : Microvascular integrity has been associated with the clinical outcomes in acute myocardial infarction (AMI). The present study was conducted to determine the value of many microvascular indexes assessed by an intracoronary (IC) pressure/Doppler wire in AMI following primary PCI for detecting viable myocardium by comparing with the 18F-fluorodeoxyglucose uptake rate (%FDG uptake) on positron-emission tomography (PET). SUBJECTS AND METHODS : We studied 35 patients who had their first AMI (age: 56+/-12, male: 30). After primary PCI, the TMPG (TIMI myocardial perfusion grade) was assessed. We measured the coronary flow reserve (CFR), the diastolic deceleration time (DDT), the coronary wedge pressure (Pcw), the Pcw/ Pa (mean aortic pressure) and the hyperemic microvascular resistance index (hMVRI) by an IC Doppler/ pressure wire. 18FDG PET scan was obtained at 7 days after the primary PCI; viable myocardium was defined that the %FDG uptake was more than 50% in infarct-related myocardium. RESULTS : There were significant correlations between TMPG, CFR, Pcw, Pcw/Pa, DDT, hMVRI and %FDG uptake (r=0.651, p<0.001; r=0.386, p=0.020; r=-0.388, p=0.021; r=-0.473, p=0.004; r=0.589, p<0.001; r=-0.442, p=0.008, respectively). The best cutoff values and area under curves (AUC) of the CFR, Pcw, Pcw/Pa, DDT and hMVRI for 50% FDG uptake were 1.8 (0.737), 27 mmHg (0.600), 0.33 (0.660), 600 msec (0.802) and 2.55 mmHg.cm-1.sec (0.768), respectively. The DDT had a significantly higher AUC than that of Pcw (p=0.029) and it was an independent index to predict the myocardial viability (p=0.011). CONCLUSION : DDT was the most reliable hemodynamic microvascular index that was assessed within 24 hours following primary PCI for predicting the viable myocardium in AMI patients.

BACKGROUND AND OBJECTIVES: High dose rosuvastatin loading before percutaneous coronary interventions (PCI) reduces the myocardial damage and the incidence of adverse cardiac events in patients with stable angina and acute coronary syndrome. However, no studies are present yet about rosuvastatin loading in patients with ST-segment elevation myocardial infarction (STEMI) in a primary PCI setting. SUBJECTS AND METHODS: A total of 475 patients who underwent primary PCI for STEMI were studied. The study population was divided into two groups with 208 patients in the statin group=40 mg rosuvastatin loading before primary PCI and 267 patients in the control group=no statin pretreatment. At median 3 days after PCI a single-photon emission computed tomography (SPECT) was performed with technetium 99m tetrofosmin For this study were compared infarct size, corrected Thrombolysis in Myocardial Infarction (TIMI) frame count and the myocardial blush grade (MBG) between the both groups. RESULTS: Baseline clinical and procedural characteristics were similar between the groups. Infarct size, as assessed by SPECT, was significantly smaller (19.0+/-15.9% vs. 22.9+/-16.5%, p=0.009) in the statin group than in the control group. Patients of the statin group showed a lower corrected TIMI frame count (28.2+/-19.3 vs. 32.6+/-21.4, p=0.020), and higher MBG (2.49+/-0.76 vs. 2.23+/-0.96, p=0.001) than the patients of the control group. The multivariate analysis revealed that rosuvastatin loading {odds ratio (OR) 0.61}, pain to balloon time (OR 2.05), anterior myocardial infarction (OR 3.89) and final the MBG (OR 2.93) were independent predictors of a large infarct size. CONCLUSION: A high dose rosuvastatin loading before the primary PCI reduced the infarct size by microvascular myocardial perfusion improvement.

BACKGROUND AND OBJECTIVES: Contrast-induced nephropathy (CIN) is associated with increased morbidity and mortality. This observational, non-randomized study evaluated the effect of rosuvastatin loading before percutaneous coronary intervention (PCI) on the incidence of CIN in patients with acute coronary syndrome (ACS). SUBJECTS AND METHODS: A total of 824 patients who underwent PCI for ACS were studied (408 patients in the statin group=40 mg rosuvastatin loading before PCI; 416 patients of control group=no statin pretreatment). Serum creatinine concentrations were measured before and 24 and 48 hours after PCI. The primary endpoint was development of CIN defined as an increase in serum creatinine concentration of > or =0.5 mg/dL or > or =25% above baseline within 72 hours after PCI. RESULTS: The incidence of CIN was significantly lower in the statin group than that in the control group (18.8% vs. 13.5%, p=0.040). The maximum percent changes in serum creatinine and estimated glomerular filtration rate in the statin group within 48 hours were significantly lower than those in the control group (5.84+/-22.59% vs. 2.43+/-24.49%, p=0.038; -11.44+/-14.00 vs. -9.51+/-13.89, p=0.048, respectively). The effect of rosuvastatin on preventing CIN was greater in the subgroups of patients with diabetes, high-dose contrast medium, multivessel stents, high baseline C-reactive protein, and myocardial infarction. A multivariate analysis revealed that rosuvastatin loading was independently associated with a decreased risk for CIN (odds ratio, 0.64; 95% confidence interval, 0.43-0.95, p=0.026). CONCLUSION: High-dose rosuvastatin loading before PCI was associated with a significantly lower incidence of CIN in patients with ACS.

BACKGROUND: The response rates and survival following allogeneic bone marrow transplantation (BMT) or immunosuppressive treatment were compared in severe aplastic anemia (SAA) and the prognostic factors related with survival identified. METHODS: Medical data of SAA patients, treated with BMT or immunosuppressive therapy (IST) at the Ajou University Hospital, between January 1995 and December 2005, were retrospectively analyzed. RESULTS: A total of 43 patients were evaluable; 18 (41.9%) were treated with IST (antithymocyte globulin plus cyclosporine A plus steroid) and 25 (58.1%) with allogeneic BMT. In the IST group, the response rate was 77.8% (2 complete and 12 partial remissions), with two treatment failures. As later complications, acute myeloid leukemia developed in 1 patient and myelodysplastic syndrome developed in 2. In the BMT group, the response rate was 92.0% (18 complete and 5 partial remissions) (P<0.001). Six patients developed grade II to III acute graft-versus-host-disease (GVHD) and 3 developed chronic GVHD. The median survival time in all patients was 60.27 months, and the 5-year survival rates were 61.0 and 81.9% in the IST and BMT groups, respectively (P=0.144). The factors influencing the overall survival were an age under 40-years and a positive treatment response. CONCLUSION: This study shows that allogeneic BMT, compared to IST, resulted in good response andoverall survival rates in patients with SAA. However, the overall survival rate between the two groups was statistically insignificant. Our study suggests that younger age SAA patients, with HLA-matched BMT donors, may benefit more from allogeneic BMT.
