PURPOSE: We performed this study to evaluate the occurrence of consecutive esotropia after early surgery in the patients with intermittent exotropia less than 4 years of age. METHODS: We analyzed the surgical results of 37 patients who underwent surgery before 4 years of age retrospectively. They were followed up at least more than 1 year after surgery. The orthophoria was defined as an exophoria of 0 to 12PD or an esophoria of 0 to 5PD after surgery. The consecutive esotropia was defined as an esodeviation lasting more than 3 months that needed surgical correction due to sensorial deterioration. RESULTS: Preoperative angle of exodeviation at distance ranged from 20PD to 60PD (mean 35.1 +/- 9.2PD). Twenty-seven of 37 patients (75.7%) showed orthophoria after surgery in 1 year follow-up and 20 of 31 patients (64.5%) in 2 years follow-up. Five patients (13.5%) showed recurrence and 4 patients (10.8%) consecutive esotropia. Immediate postoperative overcorrection was 14.1 +/- 8.7PD(0-30) in patients who were orthophoric after postoperative follow-up more than 2 years. The rate of consecutive esotropia was high in patients with an exo-angle of 30PD or more and a large amount of recession of lateral recti more than 7mm. CONCLUSIONS: This study revealed that consecutive esotropia after early surgery for intermittent exotropia less than 4 years of age was noted to the 10.8%.

The purpose of this study was to collect basic information for the development of information interchange infrastructure of health research and development library in Korea. Domestic data was collected via mail and telephone survey and site visit of information producing and distributing organizations and agencies in the health related field. Data was analyzed and tabulated using descriptive statistics. Research and development activities of the National Library of Medicine were examined using materials posted on the internet. Content of data was reviewed and summarized. It was found that we lack a standardized Korean medical subject headings for the medical librarians to refer when indexing an article written in Korean. And most of academic societies lack a standardized vocaburary system for their members to refer when wrting an article.

We studied 49 patients who showed partially accommodative esotropia retrospectively. They were glasses for accommodative component and underwent surgery for nonaccommodative one. The mean value of refractive error was +4.41 +/- 2.04 D. The mean deviation angle of accommodative component was 20.78 +/- 12.59 PD (prism diopter), and the one of non-accommodative component was 30.45 +/- 15.12 PD. Mild amblyopia was shown in 58% of these patients. The DVD or IOOA was infrequently accompanied in these patients. Stereopsis was much improved after straightening eyes. Deterioration was noticed in 14% of the patients. The longer the duration between onset and the time at straightening eyes, and the earlier the onset of deviation, the more deterioration was noticed. This study revealed that the characteristics of partially accommodative esotropia was similar to the accommodative esotropia.

Most of health care professional obtain and update their new knowledge and skills through continuing education. Nurses who works three shifts per day are not easy to attend continuing education session usually offered during their working hours. One of solutions to this problem would be to develop a education program which does not limit time and place. The aim of this study is to develop and evaluate a web-based continuing education program, to help nurse improve their knowledge of transfusion therapy and medical law, and to enhance their ability to contribute to the quality of patient care. A wide range of contents regarding transfusion therapy are covered extensively, concentration on principles of transfusion therapy and administration of whole blood and blood components, transfusion reactions. In the medical law, contents on Korean law in general, medical law, history of revision of medical law, nursing related medical laws are covered, Many color illustrations have been included to help nurses learning process. Each unit has a set of multiple choice questions to provide feedback to nurses. Two sets of questionnaires were used for this study. First, a questionnaire was administered to 21 nurses to collect information on their general characteristics, opinions of inservice and continuing education, and experiences of using computer and internet before they were exposed to the program. Second, another questionnaire was administered to 21 nurses after they were exposed to the program. They were asked to evaluate program in terms of its easiness of use, contents and ways of presenting contents, and usefulness of program for learning. The program generally was well received by the nurses. The program is a useful adjunct to the existing continuing education program. It also could be used in nursing student education and other health sciences.

PURPOSE: Duane's retraction syndrome is a congenital eye movement disorder caused by innervational disturbance. It is rare that Duane's retraction syndrome is associated with Goldenhar's syndrome which shows systemic congenital malformations. We report a case of bilateral Duane's retraction syndrome associated with Goldenhar's syndrome, which was treated with strabismus surgery and excision of epibulbar lipodermoid. METHODS: A 14-month-old boy with exotropia showed severe limitation of adduction, mild limitation of abduction, globe retraction and palpabral fissure narrowing on attempted adduction in both eyes. He also had a diffuse small epibulabar mass under the lateral conjunctiva in the left eye. The angle of exodeviation was 45PD on alternate prism cover and uncover test. He had had cleft lip, multiple skin tags on the face and preauricular appendages since birth and undergone an operation for these abnormalities at age of 4 months. Bilateral 7.5mm recession of the lateral recti and excisional biopsy of epibulbar mass of the left eye were performed. RESULTS: A case of Duane's retraction syndrome associated with Goldenhar's syndrome was found. The patient obtained orthophoria in his primary gaze after bilateral recession of lateral recti. The epibulbar mass was consistent with lipodermoid on pathologic examination.

PURPOSE: The purpose of this study was to investigate the construct equivalence of the five general factors (subjective health, eating habits, physical activities, sedentary lifestyle, and sleeping behaviors) and to compare the latent means between male and female middle school students in Incheon, Korea. METHODS: The 2008 Korean Youth Risk Behavior Survey data was used for analysis. Multigroup confirmatory factor analysis was performed to test whether the scale has configural, metric, and scalar invariance across gender. RESULTS: Configural invariance, metric invariance, and factor invariance were satisfied for latent means analysis (LMA) between genders. Male and female students were significantly different in LMA of all factors. Male students reported better subjective health, consumed more fast food and carbonated drinks, participated in more physical activities, showed less sedentary behavior, and enjoyed better quality of sleep than female students. CONCLUSION: Health providers should consider gender differences when they develop and deliver health promotion programs aimed at adolescents.

PURPOSE: To investigate the usefulness of a pharmacokinetic model based on dynamic contrast-enhanced (DCE) MR imaging for the detection and localization of prostate cancer. MATERIALS AND METHODS: Forty-four patients that had undergone radical prostatectomy for prostate cancer and dynamic contrast enhanced (DCE) MR imaging (slice thickness, 4 mm; time resolution of each set, 5 seconds), were enrolled in the study. From the pharmacokinetic model, the time of arrival, and the parameters Ah, Kep, and Kel were extracted and were compared for cancerous tissue and non-cancerous tissue in the central gland and peripheral zone. The diagnostic performance of each parameter for differentiating cancerous tissue from non-cancerous tissue was evaluated using receiver-operating-characteristics analysis. RESULTS: The Kep and Kel values were significantly greater in cancerous tissue (0.13 sec(-1) +/- 0.14 and 1.59 x 10(-3) sec(-1) +/- 1.35 x 10(-3)) than in non-cancerous tissue from the central gland (0.03 sec(-1) +/- 0.02 and 0.26 x 10(-3) sec(-1) +/- 1.24 x 10(-3)) and peripheral zone (0.04 sec(-1) +/- 0.07 and 0.58 x 10(-3) sec(-1) +/- 1.98 x10(-3)) (p < 0.05). The area under the ROC curve for differentiating cancerous from non-cancerous tissue was 0.850 (95% CI, 0.778-0.876) for Kep and 0.814 (95% CI, 0.737-0.876) for Kel. CONCLUSION: Kep and Kel are useful perfusion parameters for the differentiation of prostate cancerous tissue from non-cancerous tissue.
