Abstract
Abstract
Background
The biological effects of low-dose radiation from cardiac imaging or intervention remain largely unknown. This study aimed to evaluate the effects of ionized radiation from cardiac catheterization on genomic DNA integrity and inflammatory cytokines in patients and operators.
Methods
Peripheral mononuclear cells (MNCs) were isolated from patients (n=52) and operators (n=35) before and after coronary angiography and/or percutaneous coronary intervention. Expression of gammaH2AX, a marker for DNA double-strand breaks, was measured by immunofluorescence. Dicentric chromosomes (DICs), a form of chromosome aberrations, were assayed using a fluorescent in situ hybridization technique.
Results
In the patient MNCs, the numbers of gammaH2AX foci and DICs increased after cardiac catheterization by 101±75% and 28±99%, respectively (P<0.05 for both). The mRNA expressions of interleukin (IL)-1α, IL-1β, leukemia inhibitory factor (LIF) and caspase-1 were significantly increased by radiation exposure from cardiac catheterization. The increase in IL-1β was significantly correlated with that of gammaH2AX, but not with dose area product. In the operators, neither gammaH2AX foci nor DICs level was changed, but IL-1β mRNA was significantly increased. Protein expression of IkappaBα was significantly decreased in both groups.
Conclusions
DNA damage was increased in the MNCs of patients, but not of operators, who underwent cardiac catheterization. Inflammatory cytokines were increased both in the patients and operators, presumably through activation of NF-kappaB. Further efforts to reduce radiation exposure from cardiac catheterization are necessary both for patients and operators.

Abstract
A quantum phase estimation algorithm allows us to perform full configuration interaction (full-CI) calculations on quantum computers with polynomial costs against the system size under study, but it requires quantum simulation of the time evolution of the wave function conditional on an ancillary qubit, which makes the algorithm implementation on real quantum devices difficult. Here, we discuss an application of the Bayesian phase difference estimation algorithm that is free from controlled time evolution operations to the full-CI calculations.

Abstract
Quantum computers can perform full configuration interaction (full-CI) calculations by utilising the quantum phase estimation (QPE) algorithms including Bayesian phase estimation (BPE) and iterative quantum phase estimation (IQPE). In these quantum algorithms, the time evolution of wave functions for atoms and molecules is simulated conditionally with an ancillary qubit as the control, which make implementation to real quantum devices difficult. Also, most of the problems in chemistry discuss energy differences between two electronic states rather than total energies themselves, and thus direct calculations of energy gaps are promising for future applications of quantum computers to real chemistry problems. In the race of finding efficient quantum algorithms to solve quantum chemistry problems, we test a Bayesian phase difference estimation (BPDE) algorithm, which is a general algorithm to calculate the difference of two eigenphases of unitary operators in the several cases of the direct calculations of energy gaps between two electronic states on quantum computers, including vertical ionisation energies, singlet-triplet energy gaps, and vertical excitation energies. In the BPDE algorithm, state preparation is carried out conditionally on the ancillary qubit, and the time evolution of the wave functions in superposition of two electronic states are executed unconditionally. Based on our test, we conclude that BPDE is capable of computing the energy gap with an accuracy similar to BPE without controlled-time evolution simulations and with the smaller number of iterations in Bayesian optimisations.

Abstract
BACKGROUND AND PURPOSE With the increasing use of the Pipeline Embolization Device for the treatment of aneurysms, predictors of clinical and angiographic outcomes are needed. This study aimed to identify predictors of incomplete occlusion at last angiographic follow-up. MATERIALS AND METHODS In our retrospective, single-center cohort study, 105 ICA aneurysms in 89 subjects were treated with Pipeline Embolization Devices. Patients were followed per standardized protocol. Clinical and angiographic outcomes were analyzed. We introduced a new morphologic classification based on the included angle of the parent artery against the neck location: outer convexity type (included angle, <160°), inner convexity type (included angle, >200°), and lateral wall type (160° ≤ included angle ≤200°). This classification reflects the metal coverage rate and flow dynamics. RESULTS Imaging data were acquired in 95.3% of aneurysms persistent at 6 months. Complete occlusion was achieved in 70.5%, and incomplete occlusion, in 29.5% at last follow-up. Multivariable regression analysis revealed that 60 years of age or older (OR, 5.70; P = .001), aneurysms with the branching artery from the dome (OR, 10.56; P = .002), fusiform aneurysms (OR, 10.2; P = .009), and outer convexity-type saccular aneurysms (versus inner convexity type: OR, 30.3; P < .001; versus lateral wall type: OR, 9.71; P = .001) were independently associated with a higher rate of incomplete occlusion at the last follow-up. No permanent neurologic deficits or rupture were observed in the follow-up period. CONCLUSIONS The aneurysm neck located on the outer convexity is a new, incomplete occlusion predictor, joining older age, fusiform aneurysms, and aneurysms with the branching artery from the dome. No permanent neurologic deficits or rupture was observed in the follow-up, even with incomplete occlusion.

Abstract
Abstract
Background
DNA damage likely contributes to the pathogenesis and progression of atherosclerosis. Chemotherapy, radiotherapy and some DNA damage response (DDR) syndromes are known to increase atherosclerosis. However, causative links between DNA damage and atherosclerosis are yet to be established.
Purpose
The aim of this study was to investigate the role of impaired DDR in atherosclerosis.
Methods and results
Ku80, a DNA repair protein, -deficient apolipoprotein E knockout mice (Ku80+/− ApoE−/−) and ApoE−/m- mice were fed on high-fat diet for 4 weeks, and then oil red O staining was performed on their isolated aortas. Plaque area was significantly increased in Ku80+/− ApoE−/− mice. Immunohistochemical analysis of lesions from Ku80+/− ApoE−/− mice revealed enhanced accumulation of DNA double-strand breaks (DSBs). Similar results were obtained from Ku80+/− ApoE−/− mice fed on high-fat diet for 2 weeks which was considered as the early stages of atherosclerosis. mRNA levels of inflammatory cytokines such as IL-6 and MCP-1 in the aorta were significantly elevated in Ku80+/− ApoE−/− mice compared with those of ApoE−/− mice. To investigate whether impaired DDR is associated with the increased expression of inflammatory cytokines, vascular smooth muscle cells were isolated from Ku80 WT and Ku80+/− mice and subjected to quantitative RT-PCR analysis. mRNA levels of IL-6 and MCP-1 were significantly elevated in Ku80+/− cells. In addition, IκBα protein expression was significantly decreased in Ku80+/− cells, which suggested enhanced NF-κB activation in those cells. Immunofluorescent analysis revealed accumulation of DSBs and persistent DDR in Ku80+/− cells. In addition, elevated p16 mRNA level and senescence-associated β-gal activity were observed in Ku80+/− cells.
Conclusion
These results suggested that impaired DDR promoted atherosclerosis partly through cellular senescence and enhanced proinflammatory activation. Therefore, therapies targeting enhancing DDR may be beneficial in the prevention of DNA damage-induced atherosclerosis.

Abstract
The aim of this study was to clarify the community pharmacy-level factors related to experiences of and attitudes toward collaboration with medical and nursing home care facilities. We conducted a postal questionnaire survey of all pharmacies in Gifu, Japan, assessing the experiences and attitudes of supervising pharmacists regarding the following activities related to collaboration between medical facilities and nursing home care facilities: regional care meetings/service adjustment meetings, case discussion conferences, joint workshops/continuing education conferences, community service, information sharing through medical cooperation networks, and pharmacists accompanying physicians on home care visits. The factors significantly related to inter-professional collaboration were the family pharmacist guidance fee and the number of patients offered pharmaceutical care through cooperation with other medical facilities. Items on attitudes toward collaborating with other medical facilities showed similar results. Overall, policies that support inter-professional collaboration to create a foundation, establish mechanisms to facilitate collaboration, and identify collaborative activities that can be carried out at each pharmacy should be developed.

Abstract
INTRODUCTION The primary purpose of crosslinking is to halt the progression of ectasia. We retrospectively assessed the condition of keratoconus patients who were followed-up at least twice after the initial examination to evaluate keratoconus progression, to identify definitive factors to predict a later need for corneal crosslinking (CXL). METHODS The medical charts of 158 eyes of 158 keratoconus patients (112 males and 46 females; mean age, 27.8 ± 11.7 years), who were followed up at the Department of Ophthalmology, Keio University School of Medicine at least twice after the initial examination to evaluate keratoconus progression were retrospectively reviewed. Best-spectacle corrected visual acuity, intraocular pressure, steepest corneal axis on the anterior float (Ks), thinnest corneal thickness according to Pentacam® HR, and corneal endothelial cell density were assessed. Gender, age, onset age of keratoconus, history of atopic dermatitis, and Pentacam® indices were also recorded. CXL was performed when the eye showed significant keratoconus progression, an increase in the steepest keratometric value, or an increase in the spherical equivalent or cylinder power of the manifest refraction by more than 1.0 D versus the respective values 2 years prior. Predictor variables and the requirement for CXL were analyzed using logistic regression. RESULTS Fifty-eight eyes required CXL treatment. The best predictor of the requirement for CXL was patient age, followed by the Pentacam® Rmin (the minimum sagittal curvature evaluated by Pentacam®) value. The incidence of CXL was 86.4% in the < 20 years age group, with an Rmin of ≤ 5.73 mm, whereas 10.8% in the ≥ 27 years age group with an Rmin > 5.73 mm underwent treatment. CONCLUSIONS An age of < 20 years and an Rmin value of ≤ 5.73 mm predicted keratoconus progression and the requirement for CXL treatment in the near future.

Abstract
Rikkunshito has been shown to improve upper gastrointestinal symptoms and anorexia. The aim of this study was to evaluate whether rikkunshito improves chemotherapy-induced nausea in thoracic cancer patients receiving carboplatin (CBDCA)-based chemotherapy. A retrospective before-and-after comparison study was conducted in patients with thoracic cancer receiving the first cycle of CBDCA-based chemotherapy. Among 61 eligible patients, 34 received standard antiemetic therapy with a combination of 5-hydroxytryptamine-3 receptor antagonist and dexamethasone from September 2012 and June 2013 (standard group), while the other 27 received the standard antiemetic therapy plus oral rikkunshito from July 2013 and December 2014 (rikkunshito group). The rates of no nausea showed no significant difference between the standard and rikkunshito group (Overall phase: 64.7 % for standard group vs 74.1 % for rikkunshito group, p = 0.579). Subgroup analysis indicated that, in female patients, the rates of no nausea in rikkunshito groups was significantly higher than in standard group (overall phase: 44.4 % vs 100 %, p = 0.034). Rikkunshito did not demonstrate an additional prophylactic effect on standard antiemetic therapy for nausea in patients with thoracic cancer receiving CBDCA-based chemotherapy, but showed a prophylactic effect of nausea in female patients.

Abstract
Various types of fluorescent lights are found in the dispensing rooms of medical facilities, such as hospitals and pharmacies, in Japan. However, to reduce electric power consumption, it was necessary to evaluate the substitution of fluorescent lighting with light emitting diode (LED) lighting, which has become widespread in recent years. We subjectively evaluated several types of medicines stored under various light sources and found that different color changes were induced in tablets. In this study, we focused on Perlodel ® tablets, containing 2.5 mg bromocriptine mesylate, as an example for the objective evaluation of the differences in the color change of tablets when stored under LED lighting and fluorescent lighting. High-performance liquid chromatography (HPLC) analysis of part of the tablet surface area revealed a change from white to light brown or dark brown after 28 days of irradiation, with a residual concentration of bromocriptine mesylate of 85.5 % under fluorescent lighting, 85.6 % under daylight-color LED lighting, 90.3 % under bulb-color LED lighting, and 99.2 % in the dark. In addition, the ultraviolet (UV)-visible spectral study of the absorbance of a photo-product at 400-550 nm indicated that the color change of the Perlodel® 2.5 mg tablet was caused by photochemical degradation of bromocriptine mesylate. Thus, this analysis of the photochemical changes in drugs stored under different light sources demonstrated the potency of LED lights. Through the objective evaluation of the color change, the cause of the color change was determined; this will allow us to develop a strategy that minimizes possible disadvantages to patients, such as a decrease in treatment efficacy owing to decomposition of the main component or adverse caused by decomposed matter.

The factors significantly related to experiences of joint workshops/continuing education conferences included home care visits (odds ratio [OR] 2.39) and a 100 % out-of-hospital prescription ratio (OR 4.80). In contrast, only home care visits were significantly associated with consideration of information sharing through medical cooperation networks and accompanying community pharmacists during home care (OR 2.06 and 11.91, respectively). Finally, the factors significantly associated with considering implementing case study conferences and joint workshops/continuing education conferences included home care visits (OR 4.64 and 2.98, respectively) and a 100% out-of-hospital prescription ratio (OR 4.64 and 6.38). Overall, having more opportunities to communicate with community pharmacists and other healthcare professionals appeared to facilitate clinics' consideration of collaboration with community pharmacies, along with actual experiences.

Abstract
PURPOSE We retrospectively investigated the efficacy of corneal crosslinking (CXL) on progressive keratoconus in a Japanese population and compared the outcomes of conventional and accelerated CXL. STUDY DESIGN A retrospective cohort study METHODS: A total of 108 consecutive eyes in 95 patients (75 men; 21.9 ± 6.2 years) with progressive keratoconus were enrolled. The epithelium was ablated in all eyes. After presoaking the corneal stroma in riboflavin, UV-A was irradiated at 3.0 mW/cm2 (conventional CXL) for 30 min on 23 eyes and 18.0 mW/cm2 for 5 min (accelerated CXL) on 85 eyes. Best spectacle-corrected visual acuity (BSCVA), manifest refraction, keratometric value, corneal thickness, corneal endothelial cell density (ECD), intraocular pressure, and complications were evaluated at 1, 3, 6, and 12 months after the procedure. RESULTS BSCVA, manifest refraction, ECD, and corneal thickness did not change significantly after both procedures. The keratometric value was significantly decreased from the preoperative value at 12 months (p < 0.001). Progression to more than 1.0 D after CXL was observed in 10 eyes (9.3%). The ΔKmax was negatively associated with preoperative Kmax (p < 0.001) and positively associated with preoperative thinnest corneal thickness (p < 0.001). Both treatment modules showed no significant difference in all parameters. CONCLUSION CXL was as effective in treating keratoconus in Japanese patients as in individuals of other ethnicities. Overall, CXL could be performed using either the conventional or accelerated approach to halt the progression of keratoconus in Japanese populations.

Abstract
BACKGROUND AND PURPOSE Innovative techniques and device-related advances have improved the outcomes of neuroendovascular treatment. 3D imaging has previously used 2 × 2 binning, but 1 × 1 binning has recently been made available. The aim of this study was to evaluate the quantitative ability of conebeam CT for stent delineation and to investigate its effectiveness in the clinical environment. MATERIALS AND METHODS Four acquisition groups of 3D MIP images acquired using conebeam CT with varying conditions (acquisition time, 10 or 20 seconds and binning, 1 × 1 or 2 × 2) were compared. Two methods of analysis were performed, a phantom study and an analysis of 28 randomly selected patients. The phantom study assessed the contrast-to-noise ratio and full width at half maximum values in conebeam CT images of intracranial stent struts. In the clinical subjects, we assessed contrast-to-noise ratio, full width at half maximum, and dose-area product. RESULTS In the phantom study, the contrast-to-noise ratio was not considerably different between 10- and 20-second acquisition times at equivalent binning settings. Additionally, the contrast-to-noise ratio at equivalent acquisition times did not differ considerably by binning setting. For the full width at half maximum results, equivalent acquisition times differed significantly by binning setting. In the clinical analyses, the 10-second/1 × 1 group (versus 20 second/2 × 2) showed a higher contrast-to-noise ratio (P < .05) and a dose-area product reduced by approximately 70% (P < .05), but the difference in full width at half maximum was not significant (P = .20). CONCLUSIONS For stent-assisted coil embolization, quantitative assessment of conebeam CT showed that 10 second/1 × 1 was equivalent to 20 second/2 × 2 for imaging deployed intracranial stents. Furthermore, the 10-second/1 × 1 settings resulted in a much smaller DAP.

Abstract
BACKGROUND AND PURPOSE Paraclinoid aneurysms have been increasingly treated endovascularly. The natural history of these aneurysms has gradually been elucidated. The purpose of this study was to assess the safety and efficacy of endovascular treatment for these aneurysms. MATERIALS AND METHODS We performed a retrospective review of 377 patients with 400 paraclinoid aneurysms treated between January 2006 and December 2012. Their clinical records, endovascular reports, and radiologic and clinical outcomes were analyzed. Because aneurysms ≥7 mm are at higher risk of rupture, we classified aneurysms as small (<7 mm) or large (≥7 mm). RESULTS Overall, 115 of the 400 aneurysms (28.8%) were large (≥7 mm). Thromboembolic complications were found significantly more often with large aneurysms than with small ones (7.4% vs 1.0%, P = .001). Hemorrhagic complications were found only with small aneurysms (0.7%). The 6-month morbidity rates were similar for small (1.0%) and large (0.8%) aneurysms. Immediate angiographic outcomes were similar (P = .37), whereas recurrences and retreatment occurred more frequently with large aneurysms (P = .001 and P = .007, respectively). Multivariate analysis showed that aneurysm size was the only independent predictor for recurrence (P = .005). Most recurrences (81%) were detected by scheduled angiography at 6 months. CONCLUSIONS Aneurysm size influenced the type of complication (thromboembolic or hemorrhagic) and the recurrence rate. Given the approximately 1% annual rupture rate for aneurysms ≥7 mm, analysis of our data supports the rationale of using prophylactic endovascular treatment for unruptured paraclinoid aneurysms ≥7 mm.

Abstract
We have developed the new in situ electrical-conductivity measurement system which can be operated in ultrahigh vacuum (UHV) with accurate temperature measurement down to 20 K. This system is mainly composed of a new sample-holder fixing mechanism, a new movable conductivity-measurement mechanism, a cryostat, and two receptors for sample- and four-probe holders. Sample-holder is pushed strongly against the receptor, which is connected to a cryostat, by using this new sample-holder fixing mechanism to obtain high thermal conductivity. Test pieces on the sample-holders have been cooled down to about 20 K using this fixing mechanism, although they were cooled down to only about 60 K without this mechanism. Four probes are able to be touched to a sample surface using this new movable conductivity-measurement mechanism for measuring electrical conductivity after making film on substrates or obtaining clean surfaces by cleavage, flashing, and so on. Accurate temperature measurement is possible since the sample can be transferred with a thermocouple and∕or diode being attached directly to the sample. A single crystal of Bi-based copper oxide high-Tc superconductor (HTSC) was cleaved in UHV to obtain clean surface, and its superconducting critical temperature has been successfully measured in situ. The importance of in situ measurement of resistance in UHV was demonstrated for this HTSC before and after cesium (Cs) adsorption on its surface. The Tc onset increase and the Tc offset decrease by Cs adsorption were observed.

Abstract
To avoid the inhibition of methane production by ammonia that occurs during the degradation of garbage, anaerobic digestion with prior ammonia production and subsequent stripping was investigated. In the ammonia production phase, the maximum ammonia concentration was approximately 2800 mg N/kg of total wet sludge in the range of 4 days of sludge retention time, indicating that only 43% of total nitrogen in the model garbage was converted to ammonia. The model garbage from which ammonia was produced and stripped was subjected to semi-continuous thermophilic dry anaerobic digestion over 180 days. The gas yield was in the range of 0.68 to 0.75 Nm(3)/kg volatile solid, and it decreased with the decrease of the sludge retention time. The ammonia-nitrogen concentration in the sludge was kept below 3000 mg N/kg total wet sludge. Microbial community structure analysis revealed that the phylum Firmicutes dominated in the ammonia production, but the community structure changed at different sludge retention times. In dry anaerobic digestion, the dominant bacteria shifted from the phylum Thermotogae to Firmicutes. The dominant archaeon was the genus Methanothermobacter, but the ratio of Methanosarcina increased during the process of dry anaerobic digestion.

Abstract
PURPOSE To evaluate the use of topography-guided conductive keratoplasty in eyes with keratoconus. DESIGN Interventional case series. METHODS We examined 21 eyes in 21 patients with advanced keratoconus. Topography-guided conductive keratoplasty was performed with intraoperative monitoring of corneal astigmatism using a surgical keratometer. Uncorrected visual acuity (UCVA), best spectacle-corrected visual acuity (BSCVA), corneal topography, manifest refraction, intraocular pressure (IOP), corneal endothelial cell counts, complications, and eventual outcomes were evaluated. RESULTS UCVA (logarithm of the minimal angle of resolution [logMAR]), which was 1.65 ± 0.49 preoperatively, improved to 1.04 ± 0.64 at 1 week (P < .001) and 1.12 ± 0.61 at 1 month after surgery (P < .001). BSCVA, which was 1.02 ± 0.56 preoperatively, improved to 0.76 ± 0.65 at 1 week (P = .026) and 0.76 ± 0.60 at 1 month after surgery (P = .003). Manifest refraction, which was -15.13 ± 6.66 diopters (D) before surgery, declined to -9.97 ± 6.71 D at 1 month after surgery (P = .002). Although corneal topography reverted to the preoperative pattern and UCVA and BSCVA also regressed toward preoperative values, 12 of 21 eyes were better able to tolerate and conduct normal daily activities using contact lenses. Five subjects have undergone or are considering corneal transplantation after unsatisfactory postoperative results. No serious perioperative complication was observed. CONCLUSIONS Topography-guided conductive keratoplasty may be effective in reshaping corneal configuration in eyes with keratoconus, without serious complications, and possibly contributed to avoiding or delaying corneal transplantation.

Abstract
e15663 Background: The combination of chemotherapy and concurrent radiotherapy (CRT) has recognized as a curative alternative for several stage of esophageal cancer. On the other hands, a sufficiently long survival time has increased treatment-related late toxicities. However, the frequency and the pathogenesis of secondary malignancies that is the most serious late-onset complication are still unclear. Methods: From July 2000 to March 2008, 348 patients with esophageal squamous cell carcinoma underwent CRT. All patients received chemotherapy consisting with nedaplatin (80 mg/m2, div day1) and fluorouracil (700 mg/m2, ci day 1–5) and concurrent long T field irradiation (2 Gy daily, up to 30 Gy). A hundred patients received a single course as the neoadjuvant setting. Two cycles of CRT as the definitive or palliative setting were administered in 248 patients. Median and average follow-up durations are 8 and 21 months (1 to 92), respectively. Results: Four patients, who achieved CR after CRT, developed leukemia. Case1, 60-yo-male, developed overt acute myeloid leukemia (AML) from myelodysplastic syndrome 48 months after CRT. Cytogenetic analysis showed complicated abnormalities including deletion 5q. Case2, 64-yo-male, developed AML M0 with t(9;22)(q34;q11) 44 months after CRT. Case3, 72-yo-male, developed Burkitt leukemia with t(8;14)(q24;q32) 19 months after CRT. Case4, 65-yo-male, developed myeloid crisis of chronic myelogenous leukemia with complicated abnormalities including t(9;22)(q34;q11) 48 months after CRT. Case 1 and 3 had localized disease and received single course of neoadjuvant CRT. Case 2 and 4 had advance disease and received 2 courses of CRT. All patients eventually died of leukemia. Conclusions: Since platinum and fluorouracil have shown relatively low chance of secondary neoplasm, our data demonstrates that the concurrent radiotherapy which involves massive bone marrow tissue may increase the risk of leukomogenesis. To this end, atypical cytogenetic abnormalities seen in the present cases give a new insight into the biology of therapy-related leukemia. Notably, this is the first report presenting the incidence of secondary leukemia by nedaplatin. No significant financial relationships to disclose.

Abstract
PURPOSE To evaluate visual performance during concentrated visual work in patients wearing soft contact lenses or after LASIK. METHODS Thirty-one eyes of 17 patients who had worn soft contact lenses before LASIK were examined by the following tests immediately and 10 seconds after eye opening: 1) functional visual acuity, which is defined as visual acuity measured after prolonged eye opening without blinking; 2) surface regularity index (SRI) and surface asymmetry index (SAI) in corneal topography; and 3) higher order aberration measured with NIDEK OPD-Scan. Results were compared in the same patients before (with soft contact lenses and no eye surgery) and 1 month after LASIK (without soft contact lenses). RESULTS Functional visual acuity was significantly decreased 10 seconds after eye opening compared with immediately after eye opening, both with soft contact lenses and after LASIK, and decreased to a greater extent with soft contact lenses. The SRI and SAI were significantly increased 10 seconds after eye opening compared with immediately after eye opening, both with soft contact lenses and after LASIK, and increased to a greater extent with soft contact lenses. Higher order aberration was increased 10 seconds after eye opening with soft contact lenses, but not after LASIK. CONCLUSIONS Our results suggest that prolonged eye opening induces a decreased quality of vision in eyes of soft contact lens wearers and after LASIK. Under conditions in which blinking is restricted due to concentrated visual work, such as visual display terminal work, reading, and driving, visual performance may be more compromised with soft contact lens wear than after LASIK.

Abstract
PURPOSE To investigate the efficacy and safety of LASIK over a 5-year postoperative period. DESIGN Observational case series. PARTICIPANTS We examined 779 eyes in 402 patients with myopia or myopic astigmatism who underwent LASIK to correct their refractive errors and received regular postoperative assessments for 5 years. METHODS Postoperative examinations were performed 1 day; 1 week; 1, 3, and 6 months; and 1, 2, 3, 4, and 5 years after LASIK surgery. MAIN OUTCOME MEASURES We evaluated changes in uncorrected visual acuity (UCVA) (logarithm of the minimum angle of resolution [logMAR]), manifest refraction, best-corrected visual acuity (BCVA) (logMAR), intraocular pressure, corneal thickness, corneal endothelial cell counts, and complications. RESULTS Preoperative UCVA of 1.27 improved to -0.03 at 1 day after surgery and -0.08 at 1 month and revealed minimal but significant decreases thereafter. Postoperative manifest refraction was also improved by surgery, showing minimal but significant regression after 1 year. Final BCVA loss was seen in 10 eyes of 7 patients; in 7 cases, there were obvious reasons such as the progression of cataracts in 3 eyes, epithelial disintegrity due to dry eye in 2 eyes, irregular astigmatism due to flap striae in 1 eye, and age-related macular dystrophy in 1 eye. Intraocular pressure and corneal thickness decreased by 4.0 mmHg and 76.9 microm, respectively, due to surgery, but remained stable throughout the follow-up period. Corneal endothelial cell counts (2689.0+/-232.9 cells/mm(2) before surgery) showed a statistically significant decrease at 5 years after surgery (2658.0+/-183.1 cells/mm(2); 1.2% loss for 5 years), likely within the range due to physiological age-related loss. No serious, vision-threatening, irreversible complication such as keratectasia or progressive endothelial cell loss was observed. CONCLUSION LASIK surgery is an effective and safe procedure for correcting myopia/myopic astigmatism as long as inclusion and exclusion criteria are strictly respected. However, minimal regression occurred during the 5-year investigative period.

Abstract
SUMMARY We report the results of 26 patients who underwent stent deployment for chronic total occlusion of proximal subclavian artery. From January 1998 to October 2005, 26 patients (18 male; mean age, 62.7 years, range 22 to 83 years), 28 lesions, underwent 29 procedures of stenting for chronic total occlusion of the proximal subclavian artery.Twenty-three patients had symptoms of claudication in their arm, no patients had subclavian steal syndrome.A brachial approach was used in 21 procedures, a femoral approach was used in five procedures, and combined femoral-brachial approach was required in three procedures. Primary stent deployment was success in 24 lesions (85.7%), and secondary procedure was success in one patient, totally 25 lesions (89.3%) were successfully treated by stenting. Procedure related complication occurred in four cases, including stent migration without symptoms in two procedures, hemianopsia on next day in a case, and TIA on unclear reason in one case. Permanent morbidity rate is 3.4% in procedure. Target lesion re-treatment required in three lesions, caused by subacute thrombosis, in-stent-restenosis, and dissection of the vessel by stent edge. The cases of subacute thrombosis and in-stent-restenosis were treated by re-PTA, and the case of dissection was treated by additional stenting. Secondary patency was 100%. We conclude that stenting for chronic total occlusion of subclavian arteries appears feasible and safe.

Abstract
An interspecific hybrid medaka (rice fish) between Oryzias latipes and O. hubbsi is embryonically lethal. To gain an insight into the cellular and molecular mechanisms that cause the abnormalities occurring in the hybrid medaka, we investigated the behavior of chromosomes and the expression patterns of proteins responsible for the chromosome behavior. The number of chromosomes in the hybrid embryos gradually decreased to nearly half, since abnormal cell division with lagging chromosomes at anaphase eliminated the chromosomes from the cells. The chromosome lagging occurred at the first cleavage and continued throughout embryogenesis even after the midblastula transition. Fluorescent in-situ hybridization analyses revealed that the chromosomes derived from O. hubbsi are preferentially eliminated in both O. latipes-hubbsi and O. hubbsi-latipes embryos. Whole-mount immunocytochemical analyses using antibodies against alpha-tubulin, gamma-tubulin, inner centromere protein, Cdc20, Mad2, phospho-histone H3 and cohesin subunits (SMC1alpha, SMC3 and Rad21) showed that the expression patterns of these proteins in the hybrid embryos are similar to those in the wild-type embryos, except for phospho-histone H3. Phospho-histone H3 present on chromosomes at metaphase was lost from normally separated chromosomes at anaphase, whereas it still existed on lagging chromosomes at anaphase, indicating that the lagging chromosomes remain in the metaphase state even when the cell has proceeded to the anaphase state. On the basis of these findings, we discuss the cellular and molecular mechanisms of chromosome elimination in the hybrid medaka.

Abstract
SUMMARY In many cases, the prognosis for acute cervical carotid artery occlusion is poor. However, a standard treatment for the acute stage is not yet established. We report here the results of eight consecutive patients (mean age 71.5 years old) in which revascularization mainly by suction thrombectomy was performed under proximal protection during the acute phase. The occlusion sites were the intracranial internal carotid artery in five patients, tandem lesions of the internal carotid origin and intracranial vessel in two patients, and the common carotid artery in one patient. In addition, the subjects who received the treatment had an extent of infarction in MRI/DWI that was 1/3 or less of the internal carotid artery territory. The mean time from the onset to treatment commencement was 7.25 hours (2-28 hours). For the endovascular treatment, a guiding catheter with a balloon was used for proximal protection of the carotid artery. Revascularization was performed mainly by suction thrombectomy, and if a stenosed lesion was observed, PTA/stenting was added. Local fibrinolysis was not performed in combination with the above procedure. The treatment results were complete recanalization in three patients and partial recanalization in three patients. However, recanalization was not achieved in two patients. No hyperfusion syndrome or hemorrhagic infarction was observed postoperatively. All four patients in whom thrombi were successfully aspirated had occlusions proximal to the ophthalmic artery branch. In three of these four patients, complete recanalization was achieved. The revascularization procedure using suction thrombectomy under proximal protection was considered effective against the acute cervical carotid occlusions, in particular, those proximal to the ophthalmic artery branch.

Abstract
SUMMARY Chronic total occlusion of cerebrovascular lesions is regarded as a contraindication to revascularization. We describe a case of chronic total occlusion of intracranial internal carotid artery that iwass successfully recanalized by endovascular treatment. A 72-year-old man who presented with slight right hemiparesis was proved to have chronic total occlusion of the left intracranial internal carotid artery. Percutaneous transluminal angioplasty/stenting was achieved using reversal of flow with the Parodi Anti-Embolic System. The present case indicates that percutaneous transluminal angioplasty/stenting can be an effective therapeutic option in selected patients with chronic total occlusion of cerebrovascular lesions.

Abstract
SUMMARY We evaluated Computed Tomography Angiography (CTA) of four different self-expandable stents in phantom model. Three stents ware made of nitinol and one was made of cobaltbased alloy. Each stent placed in plastic injector, filled with diluted iodinated contrast material, and placed on a plastic case filled with saline. CTA was performed on a four-detector CT scanner (detector collimation, 0.5mm: helical pitch 3.5). Axial and longitudinal reconstructions of CT imaging were compared with the instent attenuation. Three nitinol stents showed few artifact, and cobalt-based alloy stent was appeared artificial narrowing. In conclusion, CTA is useful for follow-up examination after carotid artery stenting (CAS) as a less invasive evaluation method.

Abstract
Neoplasms of natural killer (NK)-lineage are rare. Their prognosis is generally poor except for cases of solitary nasal NK-cell lymphoma. The NK-cell Tumor Study Group performed a survey in Japan on patients diagnosed between 1994 and 1998. Of 228 patients selected for analysis, 40 underwent HSCT (15 allografts and 25 autografts). The underlying diseases were myeloid/NK cell precursor acute leukemia (n = 4), blastic NK-cell lymphoma (n = 11), aggressive NK-cell leukemia (n = 3), and nasal-type extranodal NK-cell lymphoma (n = 22). At the time of HSCT, 22 patients were in complete remission (CR), 11 were in relapse, and seven were primary refractory. All patients received myeloablative conditioning regimens including total-body irradiation. Sixteen died of disease progression, and six of treatment-related causes. Overall, 4-year survival was 39% with a median follow-up of 50 months; this was significantly better than that of patients who did not undergo HSCT (21%, P = 0.0003). For patients transplanted in CR, the 4-year overall survival was 68%, which was significantly better than that of patients who went into CR but did not undergo HSCT (P = 0.03). These findings suggest that the HSCT is a promising treatment strategy for NK-cell lineage.

Abstract
PURPOSE To investigate the anatomic variations of entrance pupil decentration and tilting angle of the iris in healthy subjects and the influence of these factors on the outcome of laser in situ keratomileusis (LASIK). SETTING Minamiaoyama Eye Clinic, Tokyo, Japan. METHODS The degree of pupil decentration and tilting angle of the iris in 2280 eyes of 1144 myopic patients without abnormal findings by ophthalmologic examination were assessed using Orbscan. Of these, 901 eyes of 467 patients had LASIK. Multiple analysis of variance (ANOVA) was used to determine risk factors for reduction of postoperative best spectacle-corrected visual acuity (BSCVA) considering patient age, refractive power, tilting angle of the iris, pupil decentration, and corneal power. RESULTS The mean pupil decentration in all eyes was 0.19 mm +/- 0.11 (SD) (range 0 to 0.9 mm); tilting angle of the iris was 4.06 +/- 1.41 degrees (range 0.19 to 12.69 degrees). By multiple ANOVA, refractive power, pupil decentration, and tilting angle of the iris were significant for the reduction of BSCVA. CONCLUSIONS Some eyes with pupil decentration or tilting angle of the iris could not be detected under typical ophthalmologic examination but only with topographic examination. Attention should be paid to eyes with large pupil decentration and tilting angle of the iris because these may be risk factors for reduction of postoperative BSCVA during corneal refractive surgeries.

Abstract
PURPOSE To investigate the efficacy and safety of implantation of an iris-claw phakic intraocular lens (PIOL), Artisan Myopia, in Asian eyes. SETTING Minamiaoyama Eye Clinic, Tokyo, Japan. METHODS Forty-four eyes of 32 Japanese patients and 1 Korean patient with high myopia had Artisan Myopia lens implantation to correct their refractive errors. Lens models, 5/8.5 or 6/8.5 (optic diameter/overall diameter), were chosen as standard lens model. A smaller lens model (5/7.5-Artisan Myopia Small) was implanted in eyes with corneal diameter less than 11.0 mm. Postoperative examinations were performed on 1 day, 1 week, 1 month, 3 months, 6 months, 1 year, and 2 years after surgery. Uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), manifest refraction, corneal endothelial cell counts, intraocular pressure, and complications were evaluated. RESULTS Artisan Myopia Small lenses were implanted in 4 eyes (9.1%) and 8.5 mm diameter lenses were implanted in 40 eyes. Preoperative UCVA (logMAR) improved from 1.57 to 0.09 at 1 month after surgery and no regression was observed thereafter. Postoperative manifest refraction was -1.02 +/- 0.87 D (-3.25 to -0.00 D), and within 1.0 D in 20 eyes (55.6%), within 2.0 D in 32 eyes (88.9%) at 1 month after surgery, and stable during the follow-up period. The final BCVA decreased 2 lines in 2 eyes (4.5%) due to progression of age-related cataract. No serious complications such as angle closure or progressive endothelial cell loss were observed. CONCLUSION Implantation of an Artisan iris-claw PIOL implantation may be a safe and effective procedure for Asian eyes.

Abstract
The purpose of our experimental study was to assess the pitfalls of distal balloon protection systems and to learn any technique tips to increase safety. Silicone carotid artery models were connected to a circulatory system to simulate arterial flow. A distal balloon protection device, PercuSurge GuardWire Plus (GWP, Medtronic Vascular) was delivered to the internal carotid artery (ICA), then was inflated to occlude ICA flow temporarily. A debris aspiration catheter (Export catheter) was delivered just proximal to the GuardWire Plus balloon coaxially, in order to introduce and diffuse particulate debris (200–500 micro meter in diameter) in the ICA stump. Then, after debris in the stump was aspirated, the GWP balloon was deflated. We recorded all the processes of our simulation experiments on a digital video and observed the movements of debris during these experiments. Exp 1) We simulated the movements of debris in the ICA stump when the GWP balloon was gradually deflated to produce a crevice between the balloon and vessel wall, simulating accidental movement of the GWP balloon during the procedure. Exp 2) In order to assess the optimal placement of the tip of aspiration catheter, the debris in the ICA stump was aspirated from three different sites (from just below the GuardWire balloon, from 2 cm below it, and from 5 cm below it). Exp 1) When the crevice appeared between GuardWire balloon and silicone tube, simulated debris began to concentrate just below the balloon. Then, some debris migrated distally from the crevice, and another part crowded in the crevice so that was impossible to aspirate and migrated in the end. Exp. 2) Debris aspiration was most effective from immediately below the GuardWire balloon, and the aspiration ability declined as the distance between the balloon and aspiration catheter became longer. According to our simulation studies, when the GWP balloon was moved accidentally during CAS procedures, or when the aspiration catheter was not delivered all the way to the GuardWire Plus balloon, distal embolization might still occur, even under protection.

Abstract
MRSA infection or colonization developed in eleven patients with neoplastic disease including malignant lymphoma (5 cases), soft tissue sarcoma (2 cases), acute myeloblastic leukemia (one), myelodysplastic syndrome (one), multiple myeloma (one), and mesothelioma (one) at our ward from October to December 1999. The infections were pneumonia (six cases), enteritis (three), bacteremia (one), and wound infection (one). Ten of 11 cases received antimicrobial agent (s) during one month before isolation of MRSA, suggesting selection of MRSA. Five cases improved and survived, but six cases died of infection. At the isolation of MRSA, the neutrophil count (NC) of the alive cases was 1, 500/microliter or more but the NC of five cases who died was less than 1,000/microliter, especially less than 100/microliter in three cases who had just received a cancer chemotherapy. Pulsed-field gel electrophoresis, performed in 9 cases, showed an identical DNA-pattern of MRSA in 7 cases, indicating a nosocomial infection. Our method to prevent spread of MRSA targeting solely the patients with MRSA infection was obviously unsatisfactory. We should target also the cases of MRSA colonization and make an effort to wash hands more vigorously. Furthermore, radical reformation such as increasing single sick-rooms drastically and increasing the number of nursing staff is also required.

Abstract
Thought Field Therapy (TFT) is a self-administered treatment developed by psychologist Roger Callahan. TFT uses energy meridian treatment points and bilateral optical-cortical stimulation while focusing on the targeted symptoms or problem being addressed. The clinical applications of TFT summarized included anxiety, adjustment disorder with anxiety and depression, anxiety due to medical condition, anger, acute stress, bereavement, chronic pain, cravings, depression, fatigue, nausea, neurodermatitis, obsessive traits, panic disorder without agoraphobia, parent-child stress, phobia, posttraumatic stress disorder, relationship stress, trichotillomania, tremor, and work stress. This uncontrolled study reports on changes in self-reported Subjective Units of Distress (SUD; Wolpe, 1969) in 1,594 applications of TFT, treating 714 patients. Paired t-tests of pre- and posttreatment SUD were statistically significant in 31 categories reviewed. These within-session decreases of SUD are preliminary data that call for controlled studies to examine validity, reliability, and maintenance of effects over time. Illustrative case and heart rate variability data are presented.

Abstract
Multiple brain and liver abscesses developed immediately after Bacillus cereus bacteremia in a neutropenic patient with acute lymphoblastic leukemia. After even 8 weeks of antimicrobial chemotherapy together with administration of granulocyte colony-stimulating factor, every infectious process disappeared but the patient's headache has still persisted. Because the wall of one brain abscess became thin and was in danger of rupturing into the ventricle, surgical drainage was performed, resulting in disappearance of headache and resolution of brain abscess. The present case indicates that a combined medical and surgical approach is mandatory to treat patients with brain abscesses.

Abstract
Diffuse large B-cell lymphoma with haemophagocytic syndrome (BCL-HS) has been reported mainly in Asia and is regarded as a distinct variant of intravascular lymphoma (IVL). However, it is unclear whether all cases of BCL-HS fall within the framework of IVL and available clinical information is limited. We analysed 25 cases with BCL-HS, including 11 autopsied cases (median, 66 years; male-female ratio, 1.1:1). The patients presented with fever, anaemia, thrombocytopenia, hepatosplenomegaly, haemophagocytosis, bone marrow invasion, respiratory disturbance and disseminated intravascular coagulopathy, but usually lacked lymphadenopathy, mass formation, neurological abnormalities and skin lesions. The clinical course was aggressive with a median survival of 7 months. The morphological findings were uniform: large lymphoid cells infiltrated vessels and/or sinusoids of the liver, marrow, lung, kidney and other organs. They were positive for CD19, CD20, CD79a and HLA-DR, but negative for CD10, CD23 and CD30. CD5 was positive in five out of 17 cases. Our critical review indicates that BCL-HS is the equivalent of the Asian variant of IVL.

Abstract
On the basis of 42 patients who used temporary nursing at home before death from February 1993 to May 2000, we examined various factors thought to influence home and hospital deaths. As a result, we realized the rates of home deaths increased since the establishment of the visit nursing section. We think that the maintenance and understanding of home medical treatment and the visit system on the part of the service providers and is necessary to realize home death.

Abstract
We report here a 20-year-old man presenting with primary nasal NK/T-cell lymphoma which showed an aggressive clinical course spreading to the spleen and skin despite various treatments. Eight months after high dose chemotherapy followed by autologous peripheral blood stem cell transplantation, acute appendicitis with perforation occurred and the patient underwent appendectomy. The histopathological diagnosis was NK/T-cell lymphoma of the appendix. Lymphoma of the appendix is extremely rare and the majority of appendiceal lymphomas are of B-cell origin. This is the first report of involvement of appendix by nasal NK/T-cell lymphoma.

Abstract
The clinical features of 25 cases of cytomegalovirus (CMV) infection complicating hematological diseases were analyzed. These cases did not undergo allogeneic bone marrow transplantation. 21 cases (84%) had a lymphoid tumor including 16 cases (64%) of malignant lymphoma and three cases of adult T-cell leukemia. All patients but one have received corticosteroid or antineoplastic agents before the occurrence of CMV infection. The types of CMV infections were interstitial pneumonia (23 cases), retinitis (2 cases), enteritis (one case), and persistent pyrexia (one case). Nine cases were diagnosed by histopathology and 5 of these 9 cases were discovered as having a CMV infection at autopsy. 20 cases were treated with ganciclovir for CMV infection, but only 9 cases improved. Of the 9 cases diagnosed by CMV-antigenemia, which had been introduced in the late 1994, 4 cases whose lymphoid tumor had been controlled responded to ganciclovir and survived but others with uncontrollable disease died. The present study indicates that the progress in the treatment of CMV infection was achieved in patients with controllable hematological disease but not in patients with refractory disease even after introduction of CMV-antigenemia.

Abstract
A case of acute lymphoblastic leukemia with a new translocation, t(5;9)(q22;q34) is reported with special reference to the clinical features and the response to treatment. This case exhibited several unique clinical features, including expression of the myeloid antigen on the early pre-B-cell phenotype, multiple bone involvement, and favorable response to donor lymphocyte infusion despite early relapse after allogeneic hematopoietic stem cell transplantation.
