Abstract
PURPOSE To describe a case series in which corneal fluorescein staining (CFS) development occurred in short break-up time (s-BUT) dry eyes after a short period during prolonged opening of the eye. METHODS The study was designed as a clinical case series. Ocular surface evaluations were performed on 13 individuals with s-BUT dry eye. Tear function examinations included Schirmer's test and BUT evaluation. RESULTS In all 13 cases, the BUT was short, but the tear quantity was not so bad. In all cases, CFS developed following a single eye opening, and the staining was observed at sites that showed as dark spots. In several cases, the CFS disappeared later. CONCLUSION In this study, we demonstrated that CFS could develop following a single eye opening. Based on our findings, CFS is a dynamic phenomenon rather than a stable indicator of ocular surface abnormalities. Moreover, s-BUT dry eye has the potential to show ocular surface abnormalities.

Abstract
PURPOSE This study aims to evaluate the effect of blocking short-wavelength light on critical flicker frequency (CFF). DESIGN This study is a prospective clinical study. METHODS Thirty-three participants (17 men and 16 women; age range, 28-39 years) were divided into 3 groups. Each group wore 1 of 3 types of lenses while performing an intensive computer task for 2 hours. To evaluate the effect of blocking short-wavelength light before and after the task, we measured the CFF and evaluated subjective questionnaires. We used the analysis of variance test to examine whether the type of lenses tested affected any of the visual fatigue-related parameters. RESULTS The type of lens worn significantly affected the CFF; however, answers to the subjective questionnaires did not differ significantly between the groups. Two of the 13 question items showed a statistical difference between lens transparency and increase in the CFF (lens 3 > lens 2 > lens 1). CONCLUSIONS The higher the blocking effect of the lens, the lower the reduction in the CFF, suggesting that blocking short-wavelength light can reduce eye fatigue.

Abstract
PURPOSE To evaluate the efficacy of two non-surgical interventions of vision improvement in children. METHODS A prospective, randomized, pilot study to compare fogging method and the use of head mounted 3D display. Subjects were children, between 5 to 15 years old, with normal best corrected visual acuity (BCVA) and up to -3D myopia. Subjects played a video game as near point work, and received one of the two methods of treatments. Measurements of uncorrected far visual acuity (UCVA), refraction with autorefractometer, and subjective accommodative amplitude were taken 3 times, at the baseline, after the near work, and after the treatment. RESULTS Both methods applied after near work, improved UCVA. Head mounted 3D display group showed significant improvement in UCVA and resulted in better UCVA than baseline. Fogging group showed improvement in subjective accommodative amplitude. While 3D display group did not show change in the refraction, fogging group's myopic refraction showed significant increase indicating the eyes showed myopic change of eyes after near work and treatment. DISCUSSION Despite our lack of clear knowledge in the mechanisms, both methods improved UCVA after the treatments. The improvement in UCVA was not correlated to measured refraction values. CONCLUSION UCVA after near work can be improved by repeating near and distant accommodation by fogging and 3D image viewing, although at the different degrees. Further investigation on mechanisms of improvements and their clinical significance are warranted.

Abstract
The cytotoxicities of diverse preparations used for dental practice were examined with normal human keratinocytes from gingival tissues by the uptake of neutral red (NR assay). Cultures from different individuals were established, and secondary cultures in serum-free medium were used. The cytotoxicities to cells treated for 2 days with gargles, mouthwashes, gingival massages, fluoride preparations, dentifrices and local anaesthetics were determined from the dose-response curves of inhibition of NR uptake. As a quantitative measure of cytotoxicity, NR(50) (the concentration of the preparations that resulted in a 50% decrease in NR uptake relative to untreated controls) was interpolated from dose-response curves. Dentifrices examined showed cytotoxicity similar to gingival massages but were more cytotoxic than any fluoride preparations, local anaesthetics, and most gargles and mouthwashes. The cytotoxicities of dentifrices were at least 6.5-fold those of fluoride preparations and 7.9-fold those of local anaesthetics. The results provide useful estimates of relative toxicities of dental preparations to human oral mucosa and are useful as a standard for cytotoxic assessment of newly developed preparations for dental use.

Abstract
A temporally and spatially resolved optical pyrometer system has been fielded on Gekko XII experiments. The system is based on the self-emission measurements with a gated optical imager (GOI) and a streaked optical pyrometer (SOP). Both detectors measure the intensity of the self-emission from laser-produced plasmas at the wavelength of 450 nm with a bandpass filter with a width of ~10 nm in FWHM. The measurements were calibrated with different methods, and both results agreed with each other within 30% as previously reported [T. Morita et al., Astrophys. Space Sci. 336, 283 (2011)]. As a tool for measuring the properties of low-density plasmas, the system is applicable for the measurements of the electron temperature and density in collisionless shock experiments [Y. Kuramitsu et al., Phys. Rev. Lett. 106, 175002 (2011)].

Abstract
Ischaemic colitis is known to be a severe emergency complication of interferon (IFN) therapy. However, as ischaemic colitis is an infrequent complication of IFN therapy, limited information is available regarding the safety of resuming IFN therapy after resolution of ischaemic colitis and subsequent recurrence. Here, we report two cases of ischaemic colitis during IFN therapy for chronic hepatitis C. Ischaemic colitis was fully healed within 1 week after its onset and IFN withdrawal, and IFN therapy was resumed following patients' wishes to do so. Ischaemic colitis did not recur after the resumption of IFN therapy, and sustained virological response was achieved in both patients. In this report, we also summarize the findings of 11 cases of IFN-associated ischaemic colitis (nine previously published cases plus our two cases) and review the clinical characteristics of ischaemic colitis during IFN therapy in patients with chronic hepatitis C.

Abstract
PURPOSE This study aimed to evaluate a newly designed compact accommodometer (CA) and compare this with a conventional accommodometer for measuring accommodation as a biomarker for aging and lifestyle. DESIGN This is an observational case series. METHODS Accommodative amplitude was measured using 2 different accommodometers in 114 patients. We obtained the data of the near-point accommodation amplitude. Subsequently, we used smoking habit as an example of lifestyle-related factor to evaluate its effect on the accommodative power. RESULTS The first part of the study included 60 eyes of 60 men and 54 eyes of 54 women, with a mean (SD) age of 43.8 (12.9) years (range, 18-58 years). There was a consistency within each measuring method despite a significant difference between the 2 devices (P < 0.01). Measuring accommodation by CA was significantly faster than by conventional modality (190.9 ± 58.1 seconds for CA and 371.8 ± 123.6 seconds for D'ACOMO, P < 0.0001, paired t test). In the second part of the study, we found a significant correlation between age and accommodative amplitude both in smokers and in nonsmokers. The accommodative amplitude of the smoker group was significantly lower than that of the nonsmoker group (P < 0.001). CONCLUSIONS Compact accommodometer may work as an alternative and convenient method in place of the conventional accommodometer for measuring accommodative amplitude as an aging biomarker. Lifestyle factors can affect the magnitude of accommodation, which can be measured by this newly developed CA.

Abstract
Background Descemet's Stripping with Automated Endothelial Keratoplasty (DSAEK) is constantly gaining popularity in the management of endothelial dysfunctions such as bullous keratopathy or Fuchs' dystrophy. Case Presentation A 36 year - old man with Fuchs' dystrophy underwent combined phacoemulsification and DSAEK of the right eye. Immediately postoperatively, corneal graft displacement and peripheral corneal edema which remained stable during the first postoperative month were evident on slit lamp examination. Three months after the procedure the peripheral edema had completely resolved and the patients' subjective symptoms were improved. Conclusions The purpose of this case presentation is to demonstrate that corneal graft displacement after DSAEK can lead to peripheral corneal edema that can resolve without further intervention such as graft repositioning or replacement.

Abstract
Two types of lunate were recognized in the midcarpal joint. Type I lunate has no facet articulation with the hamate, and Type II lunate has a facet articulation with the hamate. The purposes of this study are to estimate the biomechanical contribution of Type II lunate for Kienböck's disease, and to elucidate the change of the contact surface between the lunate and hamate during radial and ulnar deviation for both Type I and Type II. Twenty-four contralateral unaffected wrists with Kienböck's disease were used for the first purpose. The radiographic force analysis was performed with a modified two-dimensional rigid-body spring model computer-simulation technique. Six wrists of volunteers (3 of Type I and 3 of Type II lunates) were used for the second purpose. Dynamic examination on lunohamate joint was carried out using magnetic resonance imaging. The force distribution between the radius and Type II lunate was greater than that between the radius and Type I lunate statistically. Furthermore, the impingement of articular cartilages between Type II lunate and hamate was observed in ulnar deviation on dynamic study. These results suggest that Type II lunate was one of the anatomical risk factors for Kienböck's disease.

Abstract
BACKGROUND Excessive bleeding after cardiopulmonary bypass remains a major complication for cardiac surgery. The principal causes of hemostatic bleeding are related to inadequate surgical hemostasis or diluted coagulopathy. We investigated the efficacy of cryoprecipitate (Cryo) transfusion in thoracic aortic surgery with cardiopulmonary bypass. METHODS We divided 30 patients undergoing thoracic aortic surgery into two groups retrospectively. Fifteen patients transfused with cryoprecipitate and fresh frozen plasma (FFP) were defined as Group Cryo, and the other 15 patients transfused with FFP only were defined as Group FFP We compared the amount of blood products administered and the blood loss during the perioperative period between the two groups with P <0.05 to be significant. RESULTS There were no significant differences in the clinical background between the two groups. There were significant differences in the volume of blood loss (Group Cryo 544 +/- 233 ml, Group FFP 888 +/- 339 ml), requirements of FFP (Group Cryo 0.6 +/- 1.7 unit, Group FFP 4.3 +/- 6.0 unit) in ICU. CONCLUSIONS Cryoprecipitate transfusion is an effective treatment for coagulopathy caused by dilution of coagulation factors after cardiopulmonary bypass.
