AIM: To evaluate fundus findings in patients with intracranial aneurysm (ICA) to determine the relation between ICA and distinguishable retinal features.METHODS: We analyzed the medical records and ocular images of 46 patients with previously diagnosed ICA referred from the Neurosurgical Department.All patients underwent ophthalmologic evaluation including fluorescein angiography (FAG).Furthermore, the presence of drusen, macular degeneration, cotton wool spot, hard exudates, retinal hemorrhage, arteriolar attenuation, A-V crossing signs, arm-to-retina time, and A-V transit time were evaluated.The results of ICA patients (Group 1) were compared with those of 22 idiopathic epiretinal membrane patients with unaffected eyes (Group 2).RESULTS: Mean ages were 60.02y (Group 1) and 60.68y (Group 2) respectively (P=0.70).The prevalence of hypertension was similar in both groups.No case with retinal macroaneurysm was found in either group.The presence of drusen, macular degeneration, cotton wool spot, hard exudates, retinal hemorrhage, arteriolar attenuation, and A-V crossing sign was not significantly different between the two groups.Mean arm-to-retina time was not significantly different in two groups, either.CONCLUSION: We cannot find any evidence that the patients with ICA shows specific changes in the FAG and fundus.

This study was conducted to analyze how appropriate the on-line nutrition information was externally as a web information. Four-hundred-ninety-seven web sites from 5 internet search engines (Yahoo, Empas, Nate, Hanmir, Naver) were selected on the basis of April 25th, 2004. The skillful personnels monitored them about 8 evaluating categories: clarity, purpose, authority, durability, advertisement, privacy and/or security, responsibility, and contents. Forty percent of the selected web sites were operated by the companies which had commercial purpose like internet shopping malls and 5.6% by academies, societies, research institutions, schools/colleges and public institutions. Most of web sites (76.1%) were managed for advertisements and sales of companies' commodities, and 32.6% had the food and nutrition information as first purpose. Ninety-three percent of web sites were targeted to healthy individuals through whole life cycle. Specifically, there were lots of web sites for the obesity which were offered by diet related companies. Of the 497 web sites, 193 mentioned the name providing the nutrition information, but only 1/3 had reliability on their specialty. As a source of nutrition information, 52.7% of web sites were using 'books of the major field' and 42.0% 'newspapers' and 23.7% 'broadcasting', respectively. Most web sites mentioned 'setting-up date' but not 'renewal date'. Thirty-six percent of web sites took '2 - 3 days' for the operators to answer the questions through the bulletin. Forty-seven percent of web sites answered '1 - 10 questions' per 1 week, but 40.1% of them didn't answer for a week at all. There were 118 web sites (23.7%) to record the connected frequencies and 36.0% of them put the advertisements. Around 96% of web sites mentioned feedback addresses. Among the menus of web sites, 68.0% were about self-advertisement and 64.0% about nutrition information. Each web site was scored to judge its external quality according to the operators by selecting 13 items. Web sites managed by public institution had highest scores (9.5), and lowest in private vendors', food companies' and individual web pages. Among search engines, Naver got the highest score of 7.0 and Nate the lowest one of 6.1. As it was only the pilot study, there were several limits in evaluating tools, time and monitored quantity. To make monitoring of on-line nutrition informations actively, standardized monitoring forms might be developed under the integrated studies.

PURPOSE: The purposes of this study were to identify factors affecting depression in college students and the correlation of depression with self-esteem and academic stress, and to identify differences among student self-esteem, academic stress, and general characteristics and the relationship of these variables to depression. METHODS: The study was done in April 2011 with 852 students in health-related majors (medicine, nursing science, and dental hygiene) of a medical college in Korea. A self-rating survey containing 10 items from the Rosenberg Self-esteem Scale, 20 items from the Self-rating Depression Scale, and 22 items on academic stress was used. Data were analyzed using descriptive statistics, t-tests, one-way ANOVA, and logistic regression. RESULTS: Medical students' scores for self-esteem were significantly higher than dental hygiene students, but for academic stress scores, the result was the opposite. Logistic regression showed that self-esteem, academic stress, academic major and satisfaction with it (positive affect), and home income level (negative affect) significantly affected the level of depression. CONCLUSION: Designing and implementing realistic programs tailored to students' academic majors to enhance their self-esteem and provide practical knowledge in dealing with academic stress will help these students obtain a healthier school life emotionally as well as academically.

BACKGROUND AND PURPOSE: Triflusal(TR), 2-acetoxy-4-trifluoromethyl banzoic acid, is a platelet aggregation inhibitor structurally related to aspirin, proven to possess both in vitro and in vivo platelet antiaggregatoy activity. The aim of this study was to evaluate the effect of TR with different dosages on platelet function using platelet aggregation, adenosine triphosphate (ATP) secretion, and thromboxane generation after TR administration. METHODS: Twenty healthy volunteers (age 25-41years, 15 males 5 females) were randomly divided into two groups of ten subjects who were receiving one of two regimens (TR 300mg/day; TR 900mg/day) for seven days. Platelet functions including platelet aggregation by impedance methods using whole blood with ADP (5, 10uM) and collagen (1,2uM), ATP secretion and thromboxane B2 generation were determined. RESULTS: The inhibitory effect of platelet aggregation was observed in both groups. The degree of inhibitory effect was depended on the dosage of TR and the types of aggregating agent. Thromboxane B2 concentrations were significantly decreased by TR ingestion in both groups (p<0.01), but there was no differences in ATP secretion. CONCLUSIONS: This study show that TR exerts a remarkable platelet antiaggregation effect and inhibition of thromboxane synthesis in whole blood. In addition, the fact that TR does not affect ATP secretion means selective blocking of the platelet cyclooxygenase pathway.

Orbital mesenchymal chondrosarcoma, first described by Luis et. al in 1971, is a very rare tumor of characteristic histologic features. A 21-year-woman was admitted with a 4-month histoiry of rapidly progressive proptosis and visual disturbance. Right orbital exenteration was performed under the clinical diagnosis of orbital calcifying tumor. Grossly, the tumor presented as a multibloblated, circumscribed mass that measures 5.5 cm in the greatest dimentsion. Cut sections resembled ordinary chonrosarcoma. Microscopically, the tumor was composed of undifferentiated mesenchymal cells, interspersed nodules of well differentated cartilagenous tissue, areas of gradual transition from undifferentiated mesenchymal cells to cartilage, and hemangiopericytoma-like areas. A brief summary of the histopathological aspect of this tumor and a review of literature are presented.

PURPOSE: The purpose of this study was to identify the impact that health motivation, stage of change and cardiac risk factors have on health behaviors in Korean patients with coronary artery disease(CAD) admitted to hospital. METHOD: The participants in this study were 127 patients with CAD hospitalized between May 2008 and July 2009. A structured questionnaire with personal interviews and chart reviews were used to collect data. Data were analyzed using the SPSS. RESULTS: Of the relatively significant factors, including a stage of change, self efficacy, modifiable risk factor score, and perceived barriers, stage of change was found to be the most significant predictor of health behavior in patients with CAD. These variables accounted for 48.2% of the variance in health behavior. CONCLUSION: The results of the study indicate the necessity of developing a cardiac rehabilitation program for use in their daily lives after discharge from the hospital. Stage of change should be assessed for all patients with CAD being discharged from acute care hospitals.

This study was design to evaluate the efficacy of cataract surgery with simultaneous intravitreal bevacizumab injection for wet age-related macular degeneration. Of the patients who underwent anti-vascular endothelial growth factor injections, cataract surgery was performed in 24 eyes (control group), and simultaneous intravitreal bevacizumab injection was performed in 27 eyes (bevacizumab group). Best corrected visual acuity, ocular tonometry, anterior chamber inflammation, and central subfield macular thickness were measured at baseline and 1 week, 1 month, 3 months, and 6 months after surgery. The mean central subfield macular thickness increased 1 month postoperatively in the control group (p = 0.02), whereas there was no significant change in the bevacizumab group. When the preoperative and postoperative differences between the two groups were compared at each time point, the mean best corrected visual acuity improved in the bevacizumab group at 3 months after surgery (p = 0.045), and the mean central subfield macular thickness was more decreased in the bevacizumab group at 1 month after surgery compared to that of the control group (p = 0.032). Additional anti-vascular endothelial growth factor injection was performed after surgery at 1.56 ± 2.05 months and 2.52 ± 2.01 months, in the control and bevacizumab groups, respectively (p = 0.047). Simultaneous cataract surgery and intravitreal bevacizumab injection is considered an effective treatment since it reduces central subfield macular thickness in the short term, and it can delay the timing of additional anti-vascular endothelial growth factor injections after surgery.

PURPOSE: The study was done to investigate male nurses' gender discrimination, person-organization fit, organization leader-member exchange, career plateau and retention intention and to identify factors affecting nurses' retention intention for these nurses. METHODS: A cross-sectional survey was conducted using self-report questionnaires. The participants were 144 male nurses working in hospitals and other health care facilities in Korea. Data were analyzed using hierarchial regression. RESULTS: The mean score was 5.40±1.61 (out of 8) for retention intention. Factors influencing retention intention were ‘married’ (β=.27, p<.001) and ‘employment career (3~5 yr)’ (β=-.24, p=.003) in model 1, ‘person-organization fit’ (β=.42, p<.001) in model 2, ‘content plateau’ (β=-.19, p=.020) in model 3. Person-organization fit was the most significant factor followed by content plateau, employment career and married state in that order. These factors explained 33.2% of the variance in retention intention (F=17.23, p<.001). CONCLUSION: Findings indicate that it is necessary to confirm that the male nurses are suitable for their organization and improve career development at 3~5 years of work experience as a retention strategy of male nurses.
