Dynamic strategy(DS) is a fast threshold algorithm for the Octopus 101 perimeter. To analyze the efficiency of DS, we compared the results of visual field measurements using DS and conventional normal strategy(NS). Subjects comprised 60 eyes of 30 normal individuals in the 3rd decade who has not experienced perimetry before. Program G2 was performed on all subjects at random and enough intervals between the two tests(more than 1 hour). Mean testing time was 1047.63+/-219.38 seconds in NS and 684.98+/-130.95 seconds in DS. Testing time reduction rate was 32.69+/-14.35% on average. Mean defect(MD) was 2.80+/-1.02dB, 2.15+/-0.94dB in the two strategies, respectively. Corrected loss variance(CLV) was 1.31+/-0.50dB2 and 1.03+/-0.61dB2 in each test. There was significant difference in MD and CLV statistically(P<0.01). Mean short term fluctuation(SF) was 1.38+/-0.49dB and 1.45+/-0.50 dB; mean reliability factor(RF) was 2.05+/-2.73% and 1.98+/-2.80% in the two strategies, respectively. There was no significant difference in SF and RF statistically(P>0.01). It took less time with DS than NS in Octopus 101 perimeter, but further study will be needed for clinical application of DS.

PURPOSE: This study was aimed to evaluate the effect of subconjunctival retention of perfluoropropane gas on the success rates in trabeculectomized rabbits. METHODS: Fifthteen white rabbits were trabeculectomized by fornix-base conjunctival flap, full thickness sclerotomy and iridectomy. The right eye was control and the left eye was injected with 0.2 ml perfluoropropane gas(C3F8) into subconjunctival space through the 30 guage long needle. Each rabbit was examined for bleb morphology under slit-lamp microscope and measured for intraocular pressure by tonopen at preoperative, postoperative 3 days, 1 week, 2 weeks, 4 weeks, and 6 weeks. The results were analyzed by Wilcoxon rank sum test in SAS release 6.12 program. RESULTS: Mean gas retention time was 15+/-2 days. Intraocular pressure measured at postoerpative 2 weeks was statistically significantly lower in gas injected group than control group. At postoperative 2 weeks, fibrovascularization was more prominent in control group than gas injected group. Fibroblast proliferation and collagen tissue formation were more prominent in control group than gas injected group at postoperative 6 weeks. CONCLUSIONS: Subconjunctival perfluoropropane gas(C3F8) bubbles, via "spacer" effect, aid the maintenance of filtering blebs in the early postoperative period. This technique may be useful in augmenting or salvaging blebs at high risk of failure.

OBJECTIVE: To investigate the effects of combination functional electrical stimulation (FES) and standing frame training on standing balance in stroke patients. METHODS: Patients who had hemiparesis and postural instability after stroke were randomly assigned to one of the two groups; study group underwent FES on the quadriceps and tibialis anterior muscle simultaneously with standing balance training. The control group received standing frame training and FES separately. Both the groups received their respective therapies for 3 weeks. Stability index in Biodex Balance master system, Berg Balance Scale (BBS), manual muscle test, the Korean version of Modified Barthel Index, and Korean version of Mini-Mental State Examination were used to evaluate the effects of the treatment. RESULTS: In total, 30 patients were recruited to the study group and 30 to the control group. Three weeks after treatment, both the groups showed improvement in postural stability scores and physical and cognitive functions. When changes in postural stability were compared between the groups, the study group showed more significant improvement than the control group with regards to the scores of BBS and the stability indices. CONCLUSION: In this study, we found the therapeutic effectiveness of combined therapy of FES and standing frame in subacute stroke patients. The presented protocol is proposed as time-saving and can be applied easily in the clinical setting. Thus, the proposed combined therapy could be a useful method for improving standing balance in subacute stroke patients.

To investigate long term effects of CAPD on the left ventricular function in end-stage renal disease patients, M-mode echocardiographic studies and measurement o fsystolic time intervals were performed in 20 CAPD cases, 28 hemodialysis cases and 29 uremic controls. Compared to the uremic control grup, the patients on CAPD treatment revealed significant improvement of ventricular contractility and reduction of volume. On the other hand in hemodialysis group, even though there was improvement of ventricular contractility, volume control was not adequate. In the systolic time interval measurement, it is postulated that increase of PEP/LVET ratio in CAPD group probably results from reduction of volume(preload) rather than from deranged ventricular function.

PURPOSE: This study investigated the relationship among types of attribution tendencies, academic stress, coping efficacy, and academic adjustment in medical students and identified the means by which the academic adjustment of medical students can improve. METHODS: Four hundred forty-two subjects from 2 medical schools in Korea were analyzed; 202 were male, 206 were female, and 34 did not identify their gender. We surveyed their academic adjustment, attribution tendencies, academic stress, and coping efficacy. The data were analyzed by descriptive statistics, t-test, and stepwise multiple regression analysis. RESULTS: The male group scored higher on academic adjustment, internal attribution tendency, and coping efficacy but lower on academic stress than the female group. Coping efficacy and internal attribution tendency affected the academic adjustment positively while academic stress influenced it negatively. CONCLUSION: The study indicates that students with higher scores on coping efficacy and internal attribution tendency and who have lower scores on academic stress tend to adjust better academically in medical school. Therefore, these findings may be helpful for medical schools in designing effective academic adjustment programs to improve coping efficacy and internal attribution tendency and reduce academic stress. Further, these findings have important implications for planning learning consultation programs, especially in Year 1.

We experienced a case of gastric carcinoid with melena and syncope, which had a metastasis to regional lymph nodes. The gastric carcinoid tumor with massive upper gastrointestinal bleeding, which required transfusion, is very rare disease. So we report a case of gastric carcinoid with massive upper gastrointestinal bleeding with a review of relevant literature.

OBJECTIVE: To investigate the effect of upper limb rehabilitation combining robot with low-frequency repetitive transcranial magnetic stimulation (rTMS) on unilateral spatial neglect in stroke patients. METHODS: Patients who had hemispatial neglect after right hemisphere stroke were randomly divided into rTMS only group, robot only group, and combined group. All groups received conventional neglect therapy and additional treatment for each group. rTMS group received rTMS therapy. Robot group received robot therapy, while combined group received both therapies. The effect of therapy was assessed with Motor-Free Visual Perception Test-3 (MVPT-3), line bisection test, star cancellation test, Catherine Bergego Scale (CBS), Mini-Mental State Examination (MMSE), and the Korean version of Modified Barthel Index (K-MBI). These measurements were evaluated before and after treatment. RESULTS: For each group, 10 patients were recruited. There were no significant differences in baseline characteristics or initial values among the three groups. Two weeks after the therapy, all groups showed significant improvement in MVPT-3, line bisection test, star cancellation test, CBS, MMSE, and K-MBI. However, changes in measurements showed no significant differences among groups. CONCLUSION: Treatment effect of the combined therapy of robotic therapy and low-frequency rTMS therapy for hemispatial neglect was not statistically different from that of each single treatment. RESULTS: of this study did not prove the superiority of any of the three treatments. Further study with large number of patients is needed to evaluate the superiority of these treatments.
