PURPOSE: The purpose of this study was to establish a set of normative data values for saccade movements using videonystagmography and to evaluate the effects of manual correction on this data. METHODS: We examined 25 healthy subjects (9 men and 16 women). All tests were carried out by one well-instructed physician. Errors such as the wrong detection of the inflection point, missing movement, and prediction occurred during some tests. Thus, the same physician manually corrected the data by deleting error data from row results. RESULTS: We established a set of normative data for horizontal saccade movements (amplitude size 15 and 30 degrees) for mean peak velocity, latency, and accuracy. Manual correction only impacted latency and accuracy at 30 degrees horizontal, which is likely related to possible errors during the test. CONCLUSIONS: The present study provides clinically useful videonystagmography-based normative data for clinicians regarding saccade movements in Korean individuals.

PURPOSE: To evaluate optic disc pallor using ImageJ in traumatic optic neuropathy (TON). METHODS: This study examined unilateral TON patients. The optic disc was divided into 4 quadrants (temporal, superior, nasal, and inferior), consistent with the quadrants on optical coherence tomography (OCT) retinal nerve fiber layer (RNFL) thickness maps. Optic disc photography was performed and disc pallor was quantified using gray scale photographic images imported into ImageJ software. The correlation between optic disc pallor and RNFL thickness was examined in each quadrant. RESULTS: A total of 35 patients (31 male, 4 female) were enrolled in the study. The mean participant age was 34.8 +/- 15.0 years (range, 5 to 63 years). Overall RNFL thickness decreased in 6 patients, with thinning most often occurring in the inferior quadrant (28 of 35 eyes). There was a significant correlation between optic disc pallor and RNFL thickness (superior, rho = -0.358, p = 0.04; inferior, rho = -0.345, p = 0.04; nasal, rho = -0.417, p = 0.01; temporal, rho = -0.390, p = 0.02). The highest level of correspondence between disc pallor and RNFL thickness values outside of the normative 95th percentiles was 39.3% and occurred in the inferior quadrant. CONCLUSIONS: Optic disc pallor in TON was quantified with ImageJ and was significantly correlated with RNFL thickness abnormalities. Thus, ImageJ evaluations of disc pallor may be useful for evaluating RNFL thinning, as verified by OCT RNFL analyses.

Thyroid ophthalmopathy (TO) is an autoimmune inflammatory disorder involving the orbit characterized by inflammation and swelling of the extraocular muscles and an increase in orbital fat and connective tissue. Despite extensive research, TO continues to be a difficult condition for the patient to cope with and for the clinician to treat. Current treatments consist of systemic immunosuppression, orbital irradiation, and surgery. It is promising for patient refractory to conventional therapy that pathogenesis of TO at molecular level which advance development of new therapies targeting cellular immunity are now better understood. Future therapies targeting immune system or specific molecules are under investigation and show promise for the future. This review will describe current trends in the management of TO, from well-established therapies such as glucocorticoids, orbital irradiation and orbital decompression to more innovative therapies targeting immune system or specific molecules involved in TO pathogenesis.

Purpose: This study applied in-depth research methods on the level of securing mental health nurses in mental medical institutions targeting a group of experts in mental health nursing personnel, and sought paths toward revising enforcement regulations of the Mental Health Welfare Act in the future. Methods: Focus group interviews were conducted with experts experienced in conducting research on mental nursing staffing or policy development for nursing staffing. Results: Many experts in the field of psychiatric nursing must obtain additional accurate and valid support data to focus attention on the level of securing psychiatric nurses and discussing active efforts and short-and long-term strategies. Conclusion It is important to prepare evidence for the quality level of psychiatric nursing, as well as to secure adequate manpower for psychiatric nurses. In the future, it is necessary to actively use these data for policies and research relative to psychiatric nurse workforce planning.

Purpose: The purpose of this study is to investigate the patient safety status and patient safety education contents and methods perceived by nurses working in psychiatric hospitals. Methods: Data were collected using a semi-structured questionnaire for psychiatric hospital nurses who had worked for more than one year. A total of 157 questionnaires were filled and were used for analysis using descriptive statistics. Open-ended questions about the contents and methods of patient safety education were classified by each researcher and a reclassification was conducted by consensus through discussions. Results: Overall, 142 nurses (90.4%) experienced patient safety accident during the previous 1 month. Among those who experienced a patient safety accident, profanity, violence, and aggression-related accident counted for the highest percentage (82.8%). The demand for education on workplace stress management and education on psychiatric medication were the highest. Required education methods included case-by-case education on patient safety accidents, regular and continuous education, and small-scale face-to-face education. Conclusion In the future, it is necessary to actively utilize the results of this study as basic data for in-depth research on the causes of patient safety accidents, accident prevention, and the workload of nursing personnel.

PURPOSE: To evaluate the clinical characteristics of intraorbital foreign bodies as well as the treatment outcomes. METHODS: This was a noncomparative interventional case series. Clinical data and radiographic images were gathered via retrospective chart reviews of 14 patients who underwent surgical removal of intraorbital foreign bodies by an oculoplastic surgeon at the Asan Medical Center, Seoul, Korea between July 2012 and November 2015. RESULTS: The mean age of patients was 45.1 years and 13 patients (92.9%) were male. There were 9 metallic; 3 nonmetallic, inorganic; and 2 organic intraorbital foreign bodies in this series. The most common orbital complication was orbital wall fracture (8, 57.1%), and one patient had orbital cellulitis associated with a wooden foreign body. Six patients (42.9%) underwent surgical removal of foreign bodies in a delayed setting, and 4 of them needed surgery to allow for the brain magnetic resonance image tests to evaluate neurologic problems. There were 6 patients (42.9%) who had a postoperative corrected visual acuity worse than 20/200, and all of them had poor visual acuity at the time of injury due to associated eyeball or optic nerve injuries. Four patients (28.6%) had eyeball movement limitations from the initial trauma, but only 1 patient had persistent limitations postoperatively. There were no other complications associated with surgical removal. CONCLUSIONS: The majority of patients with intraorbital foreign bodies were male who had periorbital traumas. The most common foreign body was metal, and orbital wall fractures were common. The poor visual prognosis was related to the eyeball or optic nerve injuries from the initial trauma. The urgent surgical removal should be performed for organic foreign bodies or associated orbital/ocular injuries. Metallic foreign bodies may also be considered for removal to allow for possible brain magnetic resonance image evaluations in the future.

Purpose: Women are more vulnerable to post-traumatic stress (PTS) than men, causing several health problems. Nurses should understand and work with women who have experienced trauma and provide interventions to promote their physical, social, and mental health. Methods: This quasi-experimental pilot study used a one-group pre-test/post-test design. Data were collected from 14 women recruited between December 2019 and May 2020 from a self-sufficiency support center in South Korea for sexually-exploited women who had experienced trauma. The program consisted of six one-on-one intervention sessions per week for six weeks. Each session averaged 60~120 minutes. Participants were assessed at pre-test, post-test, and one-month follow-up. Changes in outcome variables over time were analyzed using the Wilcoxon signed-rank and Friedman tests. Results: The caring program for health promotion was divided into six sessions: understanding the self, sharing traumatic events and negative emotions, reframing the meaning of traumatic events, identifying thoughts and physical and emotional responses, developing health promotion activities, and maintaining a positive attitude during the process of change. As a result of the caring program, PTS (F = 36.33, p < .001), depression (F = 24.45, p < .001), health-promoting behaviors (F = 7.06, p = .004), and self-esteem (F = 19.74, p < .001) among the participants differed significantly at pre-test, post-test, and follow-up. Conclusion This study provides foundational information for the implementation of a theory-driven program by nurses in clinical and community settings to provide comprehensive care for women who have experienced trauma.

Purpose: In the present study, we aimed to establish a liquid biopsy-based monitoring method using peripheral blood cell-free DNA (cfDNA) for patients with cervical cancer who underwent radical radiotherapy (RT). Materials and Methods: Twenty-five patients with cervical cancer were prospectively recruited and treated with external beam RT and brachytherapy. In all patients, except one, chemotherapy was administered concurrently during RT. Whole peripheral blood samples were obtained at least twice from each patient. We performed next-generation sequencing (NGS) for the target-captured libraries (67 oncogenes and human papillomavirus [HPV] type 16/18) using 64 plasma cfDNA samples from the 25 participants. The ratio of HPV cfDNA and the variant allele frequency (VAF) in cfDNA was calculated, and their dynamic changes were monitored. The median follow-up duration was 25.4 months. Results: In total, we identified 21,866 cfDNA variants. ARID1A and frameshift variants occupied the largest portion of altered genes and HIGH-grade variant types, respectively. In most cases, tumor shrinkage was followed by a decrease in the HPV ratio; however, an increase in HPV ratio indicated distant metastasis, despite the reduced tumor size. The initial HPV ratio reflecting the tumor burden was likely associated with treatment outcomes (p = 0.16). We did not determine a role for serial changes in the VAF in cfDNA. Conclusion Our findings suggest that the HPV cfDNA ratio, calculated after targeted NGS, may be valuable for monitoring and predicting treatment responses. Accordingly, further validation of these findings is warranted.

PURPOSE: The purpose of this study was to test the effects on stress and depression by developing and implementing an integrated stress management program for inpatients in the psychiatric closed ward. METHODS: The study was a one-group pretest-posttest design. A total of 36 patients in the closed ward participated in this study. Data were collected through self-report questionnaires to measure hospital stress and depression. Data were analyzed by using t-tests and one-way ANOVA with SPSS/WIN 21.0. RESULTS: Integrated stress management program was designed based on Lazarus and Folkman stress-appraisal-coping model. Total of eight 1-hour sessions were delivered for four weeks in the group. There were significant differences in the inpatient stress scores before and after the intervention. However, the integrated stress management program showed some reduction in depression but did not show signifiant differences statistically. CONCLUSION: Our study findings confirm that the use of the integrated stress management program can reduce stress of the patients, that enable them to stabilize their minds at hospitalization. However, further study is needed to confirm the effects on depression. Thus, it would be beneficial to provide psychiatric nursing intervention tailored to psychiatric patients' symptoms, especially for reducing inpatient stress.

PURPOSE: To evaluate the causes and treatments of entropion and ectropion in adults. METHODS: A retrospective review was performed of 397 patients (490 eyes) with entropion and 109 patients (138 eyes) with ectropion who underwent corrective surgery at Kim's Eye Hospital from January 2009 to December 2012. RESULTS: The surgical correction of entropion was 3.5 times greater than that of ectropion. The causes of entropion were classified as senile (98.4%), cicatricial (1.4%) and spastic (0.2%). The causes of ectropion were classified as cicatricial (60.1%), paralytic (23.2%) and senile (16.7%). CONCLUSIONS: The main causes of entropion and ectropion were senile and cicatricial, respectively. Specifically, senile entropion was more common than senile ectropion, which is considered to be related to the lid anatomy of Asian patients.
