Abstract

The Over-The-Scope Clip (OTSC) can effectively treat refractory gastrointestinal diseases. However, most reports have focused on short-term effectiveness. We examined clinical outcomes of the deployed clips and long-term characteristics. Of 47 patients with OTSC treatment, 35 with follow-up periods of ≥3 months were retrospectively examined. The indications were 11 bleedings, 17 perforations, and seven fistulas. The observation period was defined as medium-term (3 to <12 months) or long-term (≥12 months). The primary outcome was the clinical success rate without disease recurrence. The secondary outcomes were the complication rate, survival duration, and clip retention rate. The medium- and long-term clinical success rates were 100% during the observation period (median, 44 months; range, 3–78 months). The complication rate was 2.9% (n = 1). The median survival time was 1,634 days for bleeding, 1,757 days for perforation, and 444 days for fistulas. The overall clip retention rates were 56.4%, 38.1%, 30.9%, and 25.9% after one, six, and 12 months and at the final follow-up, respectively. The average clip retention duration was 244 days in bleeding, 656 days in perforations, and 188 days in fistulas. Regardless of clip detachment, the OTSC can be effective in long-term.

Abstract

Much research on smart environments has focused on homes and offices. With increasing physical inactivity and its health effects, augmenting gyms to motivate, assist and coach users to track and achieve their fitness goals is important. In this paper, we propose using smart mirrors to automatically detect and count repetitions of exercises, and to provide coaching, motivation and information to users. We present the concept and use cases, developed with 7 users (novices and fitness fanatics) through contextual inquiry, and discuss how the concept can be realized with current technologies.

The chorioretinal blood flow was determined before and immediately after TES and 0.5, 1, 1.5, 2, 2.5, 3, 24, and 40 h after TES in three different areas: the margin of the optic disc, a point located midway between the optic disc and macula, and the macula area. The SBR of the stimulated eye is expressed relative to the value of the fellow eye. The mean standardized blur ratio was calculated as the ratio of the standardized SBR to the baseline SBR. The changes of intraocular pressure (IOP), blood pressure (BP), and pulse rate (PR) were determined after each measurement of the SBR. The ocular perfusion pressure (OPP) was calculated from BP and IOP.Results: The mean standardized blur ratio at the optic disc did not change significantly throughout the course of the experiment. However, the mean standardized blur ratio midway between the optic disc and macula and at the macula area were significantly higher after TES than that after sham stimulation at 3 and 24 h (P < 0.05, P < 0.01, respectively). At all times, the mean BP, PR, IOP, and OPP were not significantly different from the prestimulation values.Conclusions: TES increases the chorioretinal blood flow in normal subjects with minimal effects on the systemic blood circulation and the IOP. The increase in chorioretinal blood flow may be one of the beneficial effects that

Abstract

Background: Conventional trabeculotomy (CT) is performed in an ab-externo manner with at most 120 degrees of incision area of Schlemm's canal (SC). Recently, gonioscopy-assisted transluminal trabeculotomy (GATT), which makes possible a 360-degree incision area of SC in an ab-interno manner, is introduced. The purpose of this study was to compare surgical outcomes for CT and GATT with and without simultaneous phacoemulsification over 24 months and to identify factors associated with surgical success. Results: Patients' baseline characteristics were not significantly different between two groups. The surgical success rate in CT and GATT with phacoemulsification groups were 40.4% and 96.6% and were significantly higher in the GATT group than in the CT group (p < 0.001). However, the surgical success rate in CT and GATT without phacoemulsification groups were 40.8% and 54.2%, and there were no significant differences between two groups without phacoemulsification (p = 0.55). Similarly, the postoperative IOP was significantly lower in the GATT group than in the CT group only in eyes with simultaneous phacoemulsification. There were no significant differences in the numbers of glaucoma medications between the two groups. Additional glaucoma surgery was needed in 13.2% and 25.9% of patients in the GATT and CT groups, respectively (p = 0.157). The multivariate logistic regression analysis revealed that the surgical success of trabeculotomy was significantly associated with combined phacoemulsification and the type of glaucoma surgery (GATT). Conclusion: Although both groups without phacoemulsification had a similar surgical success and IOP-lowering effect, GATT combined with phacoemulsification had a higher surgical success rate and a greater IOP-lowering effect compared with combined CT and phacoemulsification. Multivariate logistic regression analysis showed that the factors associated with higher surgical success at one year and two years postoperatively were the combined phacoemulsification procedure and the GATT.

Abstract

Background: We report a case of a corneal disorder after breast cancer treatment with a microtubule inhibitor, nab-paclitaxel (Abraxane)., Case: A 55-year-old woman, who was referred to our clinic, presented with blurred vision. 2 weeks previously, she had been undergoing treatment with nab-paclitaxel, trastuzumab and pertuzumab. Visual acuity was 20/60 in right eye and 20/40 in left eye. Slit-lamp examination showed an atypical epithelium invasion of the cornea in both eyes and small epithelial defect in left eye. After the nab-paclitaxel treatment was discontinued the corneal findings improved. 4 months later, visual acuity was 20/15 in right eye and 20/20 in left eye., Conclusions: Nab-paclitaxel can cause severe corneal disorders, but the possibility that trastuzumab and pertuzumab combination therapy is associated with these disorders cannot be denied. Clinicians should consider the possibility of the side effects caused by systemic administration in cases of corneal disorders of uncertain etiology.

Abstract

Hepatectomy and intraarterial chemotherapy for liver metastasis from colorectal cancer have been performed in our department. Intraarterial infusion chemotherapy has also been performed for unresectable liver metastasis. One hundred twenty-seven cases of liver metastasis from colorectal cancer were studied. The cases were divided into groups according to radicability of the original colorectal cancer, whether or not hepatectomy was performed, and whether or not they received intraarterial chemotherapy. Group I is cur C of origin. Group II is cur A or B without hepatectomy. Group III is cur A or B with hepatectomy. Each group was divided into a group without intraarterial chemotherapy (A) and a group with it (B). IA 23 cases, IB 13 cases, IIA 14 cases, IIB 21 cases, IIIA 28 cases, and IIIB 28 cases. The survival rate of group III was better than that of group II. The survival rate of group II was better than that of group I. There was no significant difference in survival rates between IA and IB. The survival rate of group IIB was significantly better than that of group IIA. The survival rate of group IIIB was significantly better than that of group III A. Hepatectomy and intraarterial chemotherapy after hepatectomy for liver metastasis from colorectal cancer were effective.
