Abstract
Percutaneous coronary intervention (PCI) for the treatment of chronic total occlusion (CTO) is one of the most technically challenging areas of interventional cardiology. When CTO is combined with angulation and tortuosity of the coronary artery, the technical complexity of PCI for CTO is magnified. In this report, we describe a case of successful revascularization of a CTO lesion in the complex circumflex anatomy using a novel microcatheter (the Corsair catheter) along with an antegrade approach to facilitate guidewire passage through a proximal steep angulation and to cross the circumflex CTO lesion that was unresponsive with conventional microcatheters.

Abstract
BACKGROUND AND PURPOSE Patients with extensive leukoaraiosis are at high risk for vascular dementia. However, these patients exhibit variable severity of global cognitive impairment correlating with callosal atrophy. We hypothesized that callosal atrophy may reflect the severity of HDWM tract damage, which may explain global cognitive impairment. The purpose of this study was to evaluate HDWM tract damage by DTI and to investigate whether HDWM tract damage is associated with callosal atrophy and global cognitive impairment, in patients with extensive leukoaraiosis. MATERIALS AND METHODS Twenty-four consecutive outpatients with extensive leukoaraiosis were enrolled prospectively. The patients underwent cognitive evaluation and 3T MR imaging. The intercorrelation between cognitive score, DA of the HDWM, callosal DA, and callosal volume was analyzed statistically. The correlation of the cognitive score with DA of the HDWM and the corpus callosum was also evaluated by voxel-based analyses by using TBSS. RESULTS The patients' MMSE scores varied from 10 to 30 (mean, 25.1 ± 6.0). Reduced DA of the HDWM, reduced callosal DA, and callosal atrophy intercorrelated significantly. All of these parameters showed a significant correlation with global cognitive impairment. TBSS analyses showed a significant correlation between MMSE score decline and reduced DA in the diffuse HDWM and the corpus callosum. CONCLUSIONS In patients with extensive leukoaraiosis, atrophy and reduced DA of the corpus callosum may indicate diffuse HDWM tract damage, which may explain global cognitive impairment and development of vascular dementia.

Abstract
Japan is a country of high specific diversity of Onchocerca with eight species, the adults of two not yet known. Onchocerca dewittei japonica, a common filarial parasite of wild boar, had been proved to be the agent of five zoonotic onchocerciasis in Kyushu island with morphological and molecular studies. The sixth case, at Hiroshima in the main island, was identified to the same Onchocerca species, based on adult characters observed on histological sections. To consolidate the identification, mitochondrial cytochrome c oxidase subunit 1 (CO1) gene analysis was attempted with the formalin-fixed, paraffin-embedded parasite specimen. The sequence (196 bp) of a CO1 gene fragment of the parasite successfully PCR-amplified agreed well with those of O. dewittei japonica registered in GenBank, confirming the morphological identification. Moreover a comparison with the CO1 gene sequences of six other Onchocerca species in GenBank excluded the possibility that Onchocerca sp. from wild boar and Onchocerca sp. type A from cattle in Japan, were the causative agents in this case. Mitochondrial DNA analysis proved to be a valuable tool to support the morphological method for the discrimination of zoonotic Onchocerca species in a histological specimen.

Abstract
AIMS Long-term outcomes after sirolimus-eluting stent (SES) implantation in haemodialysis (HD) patients have remained controversial. We investigated the impact of HD on outcomes after SES implantation. METHODS AND RESULTS We analysed the data on 2050 patients who underwent SES implantation in a multi-centre prospective registry in Japan. Three-year clinical outcomes were compared between the HD group (n = 106) and the non-haemodialysis (NH) group (n = 1944). At the 3-year clinical follow-up, the rates of unadjusted cardiac mortality (HD: 16.3 vs. NH: 2.3%) and target-lesion revascularization (TLR) (HD: 19.4 vs. NH: 6.6%) were significantly higher in the HD group than the NH group (P < 0.001). Although HD group had a numerically higher stent thrombosis rate, the difference in stent thrombosis between the two groups (HD: 2.0 vs. NH: 0.7%) did not reach statistical significance. Using Cox's proportional-hazard models with propensity score adjustment for baseline differences, the HD group had higher risks of TLR [HD: 16.3 vs. NH: 6.1%; hazard ratio, 2.83; 95% confidence interval (CI): 1.62-4.93, P = 0.0003] and cardiac death (HD: 12.3 vs. NH: 2.3%; hazard ratio, 5.51; 95% CI: 2.58-11.78, P < 0.0001). The consistent results of analyses, whether unadjusted or adjusted for other baseline clinical and procedural differences, identify HD as an independent risk factor for cardiac death and TLR. CONCLUSIONS Percutaneous coronary intervention with SES in HD patients has a higher incidence of repeat revascularization and mortality compared with those in NH patients. Haemodialysis appears to be strongly associated with mortality and repeat revascularization even after SES implantation.

Abstract
Background Diabetes mellitus (DM) and impaired glucose tolerance (IGT) are risk factors for acute myocardial infarction (AMI). However, it is unknown whether hyperglycemic state is associated with increased major adverse cardiovascular events (MACE) after AMI. In this study, we evaluated the relationship between glucometabolic status and MACE in patients after AMI, and determined the critical level of 2 h post-load plasma glucose that may be used to predict MACE. Methods AMI patients (n = 422) were divided into 4 groups as follows: normal glucose tolerance (NGT) group, IGT group, newly diagnosed DM (NDM) group, and previously known DM (PDM) group. MACE of the 4 groups were compared for 2 years from AMI onset. Results The NDM group had a significantly higher event rate than the IGT and NGT groups and had a similar event rate curve to PDM group. The logistic models analyses revealed that 2 h post-load plasma glucose values of ≥160 mg/dL was the only independent predictor of long-term MACE after AMI (p = 0.028, OR: 1.85, 95% CI: 1.07-3.21). The 2-year cardiac event rate of patients with a 2 h post-load hyperglycemia of ≥160 mg/dL was significantly higher than that of patients with 2 h post-load glucose of <160 mg/dL (32.2% vs. 19.8%, p < 0.05) and was similar to that of PDM group (37.4%, p = 0.513). Conclusions NDM increases the risk of MACE after AMI as does PDM. Particularly, post-AMI patients with a 2 h post-load hyperglycemia ≥160 mg/dL may need adjunctive therapy after AMI.
