Leukoaraiosis or white matter hyperintensities are frequently observed on magnetic resonance imaging of stroke patients. We investigated how white matter hyperintensity volumes affect stroke outcomes, generally and by subtype. In total, 5035 acute ischaemic stroke patients were enrolled. Strokes were classified as large artery atherosclerosis, small vessel occlusion, or cardioembolism. White matter hyperintensity volumes were stratified into quintiles. Mean age ( standard deviation) was 66.3 12.8, 59.6% male. Median (interquartile range) modified Rankin Scale score was 2 (1-3) at discharge and 1 (0-3) at 3 months; 16.5% experienced early neurological deterioration, and 3.3% recurrent stroke. The Cochran-Mantel-Haenszel test with adjustment for age, stroke severity, sex, and thrombolysis status showed that the distributions of 3-month modified Rankin Scale scores differed across white matter hyperintensity quintiles (P < 0.001). Multiple ordinal logistic regression analysis showed that higher white matter hyperintensity quintiles were independently associated with worse 3-month modified Rankin Scale scores; adjusted odds ratios (95% confidence interval) for the second to fifth quintiles versus the first quintile were 1.29 (1.10-1.52), 1.40 (1.18-1.66), 1.69 (1.42-2.02) and 2.03 (1.69-2.43), respectively. For large artery atherosclerosis (39.0%), outcomes varied by white matter hyperintensity volume (P = 0.01, Cochran-Mantel-Haenszel test), and the upper three white matter hyperintensity quintiles (versus the first quintile) had worse 3-month modified Rankin Scale scores; adjusted odds ratios were 1.45 (1.10-1.90), 1.86 (1.41-2.47), and 1.89 (1.41-2.54), respectively. Patients with large artery atherosclerosis were vulnerable to early neurological deterioration (19.4%), and the top two white matter hyperintensity quintiles were more vulnerable still: 23.5% and 22.3%. Moreover, higher white matter hyperintensities were associated with poor modified Rankin Scale improvement: adjusted odds ratios for the upper two quintiles versus the first quintile were 0.66 (0.47-0.94) and 0.62 (0.43-0.89), respectively. For small vessel occlusion (17.8%), outcomes tended to vary by white matter hyperintensitiy volume (P = 0.10, Cochran-Mantel-Haenszel test), and the highest quintile was associated with worse 3-month modified Rankin Scale scores: adjusted odds ratio for the fifth quintile versus first quintile, 1.98 (1.23-3.18). In this subtype, worse white matter hyperintensities were associated with worse National Institute of Health Stroke Scale scores at presentation. For cardioembolism (20.6%), outcomes did not vary significantly by white matter hyperintensity volume (P = 0.19, Cochran-Mantel-Haenszel test); however, the adjusted odds ratio for the highest versus lowest quintiles was 1.62 (1.09-2.40). Regardless of stroke subtype, white matter hyperintensities were not associated with stroke recurrence within 3 months of follow-up. In conclusion, white matter hyperintensity volume independently correlates with stroke outcomes in acute ischaemic stroke. There are some suggestions that stroke outcomes may be affected by leukoaraiosis differentially depending on stroke subtypes, to be confirmed in future investigations.

The self-expandable COMPLETE stent (Medtronic) has greater elasticity, allowing it to regain its shape after the compression force reduces, and has higher trackability, thus is easier to maneuver through tortuous vessels, whereas the balloon-expandable SCUBA stent (Medtronic) has higher radial stiffness and can afford more accurate placement without geographic miss, which is important in aortoiliac bifurcation lesions. To date, there have been no randomized control trials comparing efficacy and safety between the self-expanding stent and balloon-expandable stent in advanced atherosclerotic iliac artery disease.The purpose of our study is to examine primary patency (efficacy) and incidence of stent fracture and geographic miss (safety) between two different major representative stents, the self-expanding nitinol stent (COMPLETE-SE) and the balloon-expanding cobalt-chromium stent (SCUBA), in stenotic or occlusive iliac arterial lesions. This trial is designed as a prospective, randomized, multicenter trial to demonstrate a noninferiority of SCUBA stent to COMPLETE-SE stent following balloon angioplasty in iliac arterial lesions, and a total of 280 patients will be enrolled. The primary end point of this study is the rate of primary patency in the treated segment at 12months after intervention as determined by catheter angiography, computed tomography angiography, or duplex ultrasound.The SENS-ILIAC trial will give powerful insight into whether the stent choice according to deployment mechanics would impact stent patency, geographic miss, or stent fracture in patients undergoing stent implantation in iliac artery lesions.National Institutes of Health Clinical Trials Registry ( identifier: NCT01834495 ), registration date: May 8, 2012.

Although acute bronchitis is quite common, there is relatively limited information regarding the microorganisms that are involved in this illness.We performed a prospective study of acute bronchitis at 31 hospitals and clinics in Korea from July 2011 to June 2012. Sputum specimens were collected for polymerase chain reaction (PCR) and culture of microorganisms.Of the 811 enrolled patients, 291 had acceptable sputum specimens that were included for analysis of the etiologic distribution. With multiplex PCR testing, viruses were identified in 36.1% (105/291), most commonly rhinovirus (25.8%) and coronavirus (3.8%). Typical bacteria were isolated in 126/291 (43.3%) patients. Among these patients Haemophilus influenzae (n = 39) and Streptococcus pneumoniae (n = 30) were isolated most commonly; atypical bacteria were identified in 44 (15.1%) patients. Bacteria-only, virus-only, and mixed infections (bacteria plus virus) accounted for 36.7% (98/291), 17.2% (50/291), and 18.9% (55/291) of infections, respectively. In particular, 52.4% of patients with viral infection had a concurrent bacterial infection, and rhinovirus was the most common virus in mixed infections (40/55). Additionally, infections with typical bacteria were more common in patients with chronic lung disease (p = 0.029), and typical bacterial infections showed a trend towards a higher prevalence with older age (p = 0.001).Bacteria were associated with almost half of community-acquired acute bronchitis cases. Additional studies are required to further illuminate the role of bacteria and to identify patient groups most likely to benefit from antibiotic treatment.

Patients with acute ischemic stroke (AIS) are at high risk of subsequent vascular events. The aim of this study was to estimate rates of recurrent stroke, myocardial infarction (MI), and major vascular events during the first year after AIS in Korea.Through a multicenter stroke registry in Korea, 12,227 consecutive cases of AIS were identified between November 2010 and May 2013 and were followed up for recurrent stroke, MI, and major vascular events up to 1 year after stroke.Cumulative 30-day, 90-day and 1-year rates were 2.7%, 3.9%, and 5.7% for recurrent stroke; .1%, .3%, and .5% for MI; and 8.1%, 10.6%, and 13.7% for major vascular events, indicating that the early period is at high risk of recurrent stroke and major vascular events. The risk of recurrent stroke was substantially higher than the risk of MI: 13.0 times at 90 days and 11.4 times at 1 year. Compared to those with small-vessel occlusion (SVO), those with ischemic stroke subtypes other than SVO had a higher risk of recurrent stroke as well as major vascular events. Other common independent predictors for recurrent stroke and major vascular events were diabetes and prior stroke history.During the first year after AIS, one in 18 had recurrent stroke and one in 7 major vascular events. More than two thirds of recurrent stroke and three quarters of major vascular events developed within 90 days in a Korean cohort of stroke patients. Better prevention strategies are required for high-risk patients during this high-risk period.

Background: There has been no consensus regarding the optimal treatment durations and drug regimens in patients with endoscopic submucosal dissection (ESD)induced ulcers. Objective: To assess the efficacy of proton pump inhibitor (PPI) and rebamipide combination therapy compared with PPI monotherapy for ESD-induced ulcer healing. Design: Randomized, prospective, controlled study; clinical trial. Setting: Five hospitals in a University Medical Center group in Korea. Patients: This study involved 290 adults (309 lesions) who underwent ESD for gastric adenoma or early gastric cancer. Intervention: PPI and rebamipide combination therapy. Main Outcome Measurements: The ulcer healing rate at 4 weeks after ESD. Results: The ulcer healing rates at 4 weeks after ESD in the PPI and rebamipide combination therapy group were significantly higher than those in the PPI alone group, both in the full analysis (94.9% vs 89.9%; P <.0001) and in the per-protocol analysis (94.5% vs 91.2%; P =.020). This combination therapy was an independent predictive factor for a high ulcer healing rate (adjusted odds ratio [OR] 5.572; 95% confidence interval [CI], 2.615-11.876; P =.014). Additionally, the combination therapy group exhibited a higher quality of ulcer healing than the PPI monotherapy group (reviewer 1: P =.027; OR 1.949; 95% CI, 1.077-3.527; reviewer 2: P =.027; OR 1.933; 95% CI, 1.074-3.481). Limitations: Open-label study. Conclusion: PPI and rebamipide combination therapy had a superior 4-week ESD-induced ulcer healing rate and quality of ulcer healing compared with PPI monotherapy.

Background: To determine the aqueous humour levels of vascular endothelial growth factor (VEGF) and erythropoietin (EPO) in eyes with diabetic macular oedema before and after intravitreal EPO injection. Design: Prospective interventional case series. Participants: Eleven eyes of 11 patients with diabetic macular oedema, and 10 eyes of 10 patients with cataract surgery as controls. Main Outcomes Measures: EPO and VEGF levels in aqueous humour before and after intravitreal EPO injection in patients and compared with controls. Methods: Eyes with diabetic macular oedema received an intravitreal injection of EPO (1000IU/0.05mL), followed by various intraocular procedures at different intervals (1-54days) after injection. An aqueous humour sample was obtained and aqueous humour levels of EPO and VEGF were measured using enzyme-linked immunosorbent assay. Results: The aqueous levels of EPO and VEGF were significantly elevated in diabetic macular oedema eyes compared to control eyes (P<0.05). EPO levels in patients correlated with VEGF levels (r=0.816, P=0.002) and central macular thickness at baseline (r=0.618, P=0.043). After intravitreal EPO injection, aqueous EPO levels were significantly elevated, whereas aqueous VEGF levels were varied according to the time interval since injection. Visual acuity and central macular thickness were not different after injection, compared to before injection. Aqueous EPO levels did not correlate with serum EPO levels(r=0.299, P=0.371). Conclusions: EPO is locally expressed and is correlated with VEGF in eyes with diabetic macular oedema. The role of EPO and the effect of intravitreal EPO in patients with diabetic macular oedema need to be further defined. © 2011 The Authors.

Pretest probability (PTP) and an exercise treadmill test (ETT) are recommended for the initial evaluation of possible coronary artery disease (CAD), but the applicability of these tests in Korean women has not been evaluated.Korean women with PTP, ETT, and invasive coronary angiography results were enrolled. Across all PTP levels, PTP and ETT statistics were evaluated and independent CAD predictors obtained.Of the 335 patients (mean age 58.010.2 years), 99 and 236 were in the low (LPTP) and intermediate PTP (IPTP) groups, respectively. The observed prevalence of CAD was significantly lower than the PTP. (7.1% vs. 9.14.9% in LPTP, p<0.001; 23.3% vs. 33.015.1% in IPTP, p<0.001) The ETTs sensitivity and positive predictive values (PPVs) appeared lower than previously reported (LPTP: 42.9% and 16.7%; IPTP: 61.8% and 37.0%), whereas the negative predictive values (NPVs) were higher (LPTP: 95.1%; IPTP: 85.4%). After multivariate adjustments, positive ETT (odds ratio 3.276, 95% confidence interval 1.643-6.532, p=0.001) independently predicted the presence of CAD, but the PTP showed only marginal predictability (odds ratio 1.019, 95% confidence interval 0.998-1.041, p=0.069).In Korean women, the observed prevalence of CAD was lower than the PTP, and PTP showed only marginal CAD predictability. Although a positive ETT independently predicted CAD, the ETT showed lower sensitivity and PPVs than previously reported. Despite the limited value of PTP and ETT, the high NPVs of ETT appear useful for saving patients from unnecessary further examinations.
