Leiomyoma is a common benign tumor of smooth muscle cells that rarely occurs in the retroperitoneum. Here, we report a retroperitoneal leiomyoma with exophytic growing into the lesser sac incidentally diagnosed in a 69-year-old woman. In this case, the retroperitoneal leiomyoma presented as a well-circumscribed mass with heterogeneous signal intensity and mild progressive enhancement on magnetic resonance imaging. Differential image diagnosis of this retroperitoneal leiomyoma from other retroperitoneal tumors was difficult due to an overlap in imaging appearances with other retroperitoneal tumors.

Purpose: This meta-analysis was conducted to determine the effect size of anxiety and psychological outcomes of virtual reality interventions in patients with anxiety disorders. Methods: A total of 835 studies were initially identified, of which six were found to be suitable according to the PICO (P: Patients with social phobia, I: VR technology, C: non VR technology, O: Variables related to mental health). criteria. Results: An analysis of the effect size of these studies confirmed that virtual reality interventions were not statistically significantly effective for generalized anxiety disorder (standardized mean difference [SMD]=0.16, 95% confidence interval [CI]=-0.84 to 1.15), but exhibited statistically significant effects for social anxiety (SMD=-0.56, 95% CI=-0.87 to -0.25) disorder and relational anxiety disorder (SMD -0.83, 95% CI=-1.49 to -0.16). Although these interventions were not statistically significantly effective for depression (SMD=-0.40, 95% CI=-0.84 to 0.04), they were effective in reducing negative emotions (SMD=-0.75, 95% CI=-1.20 to -0.31). Conclusion Virtual reality interventions based on the desensitization effect may be considered a viable option for reducing anxiety disorders.

Light chain deposition disease (LCDD) is characterized by the deposition of abnormal immunoglobulin light chains in many organs, including kidney. It is usually associated with multiple myeloma or other lymphoproliferative disorders. Myeloma usually occurs in old age and may develop after renal transplantation thus being categorized as posttransplant lymphoproliferative disease (PTLD). Renal LCDD usually presents with variable degree of proteinuria and renal insufficiency. The diagnosis of LCDD depends on histologic findings with detection of monoclonal immunoglobulin light chain. Histologically, it is characterized by nodular glomerulosclerosis. We report the first case of de novo LCDD associated with myeloma after renal transplantation in Korea. With advancing renal transplantation and increasing old aged renal recipients, myeloma or LCDD should be included in the differential diagnoses of renal recipient patients with deteriorating renal function.

This study was undertaken to assess the lateral ventricle, which was some portion of brain and related to congenital anomalies, from 1, 2, 4, and 8 months of age in healthy micropigs. They were induced general anesthesia and performed magnetic resonance imaging (MRI) with a 0.3 Tesla magnet. Each age group was evaluated by three subjects such as lateral ventricular volume, ventricular volume ratio and asymmetry. T1 weighted transverse images were acquired for calculation of lateral ventricular and corresponding brain parenchyma areas. The ratio of bilateral ventricle areas used to analyze the asymmetry. The mean ventricular volumes of each month were 676.74 +/- 25.58 mm3 (1 month-old), 630.64 +/- 143.84 mm3 (2 month-old), 992.12 +/- 106.03 mm3 (4 month-old) and 1172.62 +/- 237.57 mm3 (8 month-old), respectively. The ventricular volume ratio was the smallest at 2 month-old and re-increased from that age. The ratio was significantly different between 2 month-old and other age groups (p < 0.05). The value of bilateral area ratio showed within 1.5 in all experimental animals. Consequently the lateral ventricle showed a positive correlation with aging and symmetric shapes in both sides. The developmental pattern of the lateral ventricle provides basic data in micropigs as an experimental animal model for physiological and neurosurgical approach.

Pacemaker lead endocarditis is treated with total removal of the infected device and proper antibiotics. The outcomes of patients undergoing percutaneous lead extraction for large vegetations (>2 cm) have not yet been shown. In this case report, we present two patients with pacemaker lead endocarditis with large vegetations of maximum diameter 2.4 cm and 3.2 cm. The first patient had multiple vegetations attached to the tricuspid and mitral valves and developed septic emboli to the brain, lung, and liver. The second patient had a large, persistent vegetation on the tricuspid valve, even two weeks after complete removal of the leads. Both patients were successfully treated with transvenous pacemaker lead removal and antibiotics.

OBJECTIVES: This study aims to investigate the risk of posttraumatic stress disorder (PTSD) and its related factors among firefighters dispatched to the rescue sites after the Great Japanese Earthquake in 2011. METHODS: Among 104 male firefighters dispatched to rescue sites after the Great Japanese Earthquake, 73 firefighters were assessed. The 73 firefighters completed questionnaires, which include general characteristics, an impact of event scale-revised Korean version (IES-R-K), a coping checklist, a scale of perceived social support, and a post-traumatic stress diagnostic scale (PDS). The data was analyzed to find factors related to PTSD risk. RESULTS: The mean value of age and work tenure in this study were 38.6 years (SD=5.7) and 11.6 years (SD=6.0), respectively. The number and rate of the PTSD high-risk group in dispatched firefighters in this study was 7 cases and 9.6% using IES-R-K, with an over 25-point cutoff score. The mean rank of tenure, 53.5 in the PTSD high-risk group (n=7), was significantly higher than that of 32.2 in the PTSD low-risk group (n=66). The mean rank of assessable support, 20.2 in the PTSD high-risk group was significantly lower than that of 38.7 in the PTSD low-risk group. In logistic analysis of model 1 including PDS in independent variables, were associated with being a PTSD high-risk group as in the following: higher PDS score (OR 2.18, 95% CI: 1.07~4.46), longer tenure (OR 3.42, 95% CI: 1.01~11.89), more using coping method (OR 1.35, 95% CI: 1.00~1.81), and lower perceptions of social support (OR 0.84, 95% CI: 0.72~0.97). In logistic analysis of model 2 without PDS in independent variables, more using coping method (OR 1.14, 95% CI: 1.01~1.28) and lower perceptions of social support (OR 0.95, 95% CI: 0.91~0.98) were associated with being a PTSD high-risk group. CONCLUSION: The PTSD high-risk group in dispatched firefighters indicated that their odds ratios were increased when they used more coping methods under specific stress conditions and had lower perceptions of social support. Therefore, for those, who might be dispatched to overseas, the psychological support approach should be considered to produce effective coping methods against traumatic events and to be aware of abundant resources for social support regarding the problem.

PURPOSE: The purposes of this study are to examine differences in job satisfaction among professional groups including nurses, allied hospital professionals, social workers, and elementary school teachers, and to identify specific characteristics of job satisfaction of nurses. METHODS: The study design was a cross-sectional exploratory study using secondary data analysis with the 2009 Graduates Occupational Mobility Survey. The sample was female new graduates. The differences in job satisfaction among professional groups were analyzed using logistic regression (satisfied vs. not satisfied). RESULTS: Overall, 41.5% of nurses, 50.1% of allied hospital professionals, 58.2% of social workers, and 89% of elementary school teachers were satisfied with their job. Nurses were significantly less satisfied than the other professionals in 5 of the 11 job characteristics and had the lowest odds ratio (OR) when compared with elementary school teachers: work content (OR = 0.197, 95% CI [0.128, 0.304]), physical work environment (OR = 0.353, 95% CI [0.236, 0.529]), working hours (OR = 0.054, 95% CI [0.033, 0.088]), personal growth (OR = 0.242, 95% CI [0.160, 0.366]), and autonomy (OR = 0.188, 95% CI [0.123, 0.288]). Work content, physical work environment, interpersonal relationship, advancement system, and autonomy were significantly associated with the overall job satisfaction of nurses. CONCLUSION: Relatively dissatisfying job characteristics in nursing work environment that were significant predictors for nurses' job satisfaction should be improved. Newly graduated nurses are at risk for job dissatisfaction. This can result in high turnover rates and can exacerbate the nursing shortage. Efforts to improve the work environment are needed.

PURPOSE: To compare neodymium-doped yttrium aluminum garnet (Nd:YAG) laser capsulotomy rates between hydrophobic and hydrophilic intraocular lenses. METHODS: The present retrospective study enrolled patients who received cataract surgery from a single surgeon between July 2006 to December 2009. Patients included in the study were implanted with SA60AT hydrophobic spherical intraocular lenses (Alcon, Fort Worth, TX, USA, 268 eyes) or I-FLEX hydrophilic spheric intraocular lenses (i-Medical®, Ophthalmic International Heidelberg GmbH, Mannheim, Germany, 331 eyes). The Nd:YAG capsulotomy rates and best-corrected visual acuity (BCVA) were compared between the two groups for 2 years after the operation. RESULTS: The mean follow-up period was 23.5 months and 22.6 months and the mean age was 68.6 years and 70.3 years in the SA60AT and I-FLEX groups, respectively. Follow-up periods were longer in the SA60AT group (p = 0.035), but ages were not significantly different between the two groups (p = 0.367). Nd:YAG laser capsulotomy rates were 6.3% in the SA60AT group and 11.2% in the I-FLEX group. Nd:YAG laser capsulotomy rates were significantly higher in the I-FLEX group (p = 0.020). BCVA before and after the Nd:YAG laser capsulotomy was not significantly different. CONCLUSIONS: Nd:YAG laser capsulotomy rates were higher in the I-FLEX hydrophilic spheric intraocular lens group than in the SA60AT hydrophilic spheric intraocular lens group. Adhesion between capsular bag and intraocular lens by bioadhesive character of hydrophobic acryl intraocular lens may contribute to the prevention of lens epithelial migration and posterior capsule opacification.
