The purpose of this study was to perform the radiographic measurements and temporomandibular joint evaluation in mandibular asymmetry. For this study, thirty-two patients who have mandibular asymmetry were selected and submentovertex, panoramic and lateral corrected tomographic radiagraphs were taken. Horizontal and vertical analysis using various landmarks on these radiographs were performed. Also radiographic and clinical evaluation of temporomandibular joint were obtained. Ther results were as follows ; 1. On the submentovertex radiograph, the mean distance of Pogonion to midline was 5.0(+/-)3.8mm. 2. The mean distance of Pogonion to Gonion between the deviated and the contra-lateral side(P<0.001). 3. The distance difference of Pogonion to Gonion between the deviated and the contra-lateral side was significantly realated to the degree of asymmetry(P<0.001). 4. On panoramic radiagraph,the condylar height of the contral-lateral side was significantly longer than the one of the deviated side(P<0.001). 5. On lateral corrected tomogram, bony of temporomandibular joint was observed in 11 condyles of the deviated side and 9 condyles of the contra-lateral side. Erosion and ostephyte were the most common changes in both the deviated and the contra-lateral sides.

We report a case of solitary congenital calcified nodule of the ear in a 1-year-old female. The lesion was a 2 X 2mm-sized, elevated, slightly erythematous and whitish-centered nodule located since birth on the superior helical rim of her left ear. Histopathological findings fram the totally excised lesion showed calcium deposits as amorphous, basophilic masses in the upper dermis and focal discharge of calcium by means of transepidermal elimination. Surrounding the calcium deposits, lymphohistiocytic infiltrations were present.

PURPOSE: To analyze the possible association between magnetic resonance imaging signal intensity of temporo-mandibular joint disk and posterior attachment, and the type and extent of disk displacement, disk configuration, effusion and clinical signs in patients with internal derangement. MATERIALS AND METHODS: Magnetic resonance images of the 132 temporomandibular joints of 66 patients with temporomandibular joint displacement were analyzed. The clinical findings were obtained by retrospective review of the patients' records. The type and extent of disk displacement, disk configuration and effusion were evaluated on the proton density MR images. The signal intensity from the anterior band, posterior band and posterior attachment were measured on MR images. The associations between the type and extent of disk displacement, disk configuration, effusion and clinical signs and the MR signal intensity of disk and posterior attachment were statistically analyzed by student's t-test. RESULTS: Of 132 joints, 87 (65.9%) showed anterior disk displacement with reduction (ADR) and 45 (34.1%) showed anterior disk displacement without reduction (ADnR). The signals from posterior attachments were lower in joints with ADnR than those of ADR (p<0.05). The results showed statistically significant (p<0.05) association between the type and extent of disk displacement and disk configuration, and decreased signal intensity of posterior attachment. There were no statistical associations between pain, noise and limited mouth opening, and signal intensity of disk and posterior attachment. Conclusions : The average signal from posterior attachment was lower in joints with ADnR than that of ADR. The type and extent of disk displacement and disk configuration appeared to be correlated with the signal intensity from posterior attachment.

PURPOSE: The purpose of this study was to identify the effect of the exchange of saline used in surgical procedures on surgical site infections. METHOD: Patients with stomach cancer were assigned to the experimental group or to the control group by random sampling, respectively. The experimental group received an exchange of saline during the operation right after the excision of the stomach in a gastrectomy but the control group did not. Data were collected from the medical charts of 34 patients from Dec. 1, 2002 through May 31, 2003. RESULT: The surgical site infection rate of the experimental group was 5.9% while surgical site infection rate of the control group was 17.6%. In total, the surgical site infection rate was 11.8%. The experimental group maintained a normal level of WBC on post operative day 3; however, the control group, showed an increase of WBC on post operative day 3. CONCLUSION: The exchange of saline used in an operation immediately after the excision of the stomach in a gastrectomy decreases the contamination level of saline used in the operation, and can prevent surgical patients from a surgical site infection.

Reticulohistiocytoma, a rare form of non-Langerhans cell histiocytoses, usually presents it-self as a single cutaneous nodule mainly on the head and neck of young men without associated arthritis. We describe an 18-year-old male patient with a red dome-shaped nodule of 2 months' duration on the scalp. Histologic examination of the excised mass revealed numerous large, mononucleated or multinucleated histiocytes with abundant eosinophilic, finely granular cytoplasm having a ground-glass appearance. Immunohistochemical staining was positive for vimentin, lysozyme, and factor XIIIa, supporting a dermal dendrocyte lineage. Ultrastructurally, large mononuclear or multinucleated cells exhibiting numerous peripheral villi contained pleomorphic cytoplasmic inclusions, fatty droplets and dense bodies. Our clinicopathologic findings support the concept that reticulohistiocytoma is a variant of adult xanthogranuloma.

PURPOSE: This study was done to identify the relationship of emergency department(ED) nurse's job characteristics, organizational commitment and turnover intention. METHOD: This study was conducted through a survey of 171 nurses from ED in nine general hospitals of B and U cities. The data were collected by self-report questionnaires and analyzed with the SPSS WIN 17.0 program using descriptive statistics, t-test, ANOVA, Pearson correlation coefficient and stepwise multiple regression. RESULTS: The mean score for job characteristics was 3.37. Job characteristics according to position, number days night duty, and monthly income showed significant differences. Turnover intention according to age, total career, and monthly income showed significant differences. A significant positive correlation was found between job characteristics and organizational commitment. Significant negative correlations were found between job characteristics and turnover intention, organizational commitment and turnover intention were found. The significant factors influencing turnover intention were organizational commitment, monthly income, and total career, which explained 27.6% of the variance. CONCLUSION: The findings indicate that nurse managers should analyze the reasons for high turnover intention, focusing on the main factors affecting turnover intention and consider solutions for decreasing turnover intention.

PURPOSE: The purpose of this study was to identify the factors influencing emergency department (ED) nurses' turnover intention. METHODS: The study was conducted with 241 nurses from ED of 20 general hospitals in Busan. The survey data were collected from May 1 to July 31, 2010 and were analyzed using frequencies, percentages, means, t-test, ANOVA, Pearson correlation coefficient and stepwise multiple regression with the SPSS Win 17.0 program. RESULTS: There were statistically significant differences in turnover intention depending on age, regular change in department, and nursing experiences. A significant positive correlation was found between job stress and turnover intention and a significant negative correlation between organizational commitment and turnover intention. The significant factors influencing turnover intention were regular change in department, job stress, and organizational commitment, which explained about 13.7% of the variance. CONCLUSION: Considering this results, nursing managers should analyze these main factors which affect turnover intention and create ways to decrease turnover intentions, and thus decrease high turnover intention.
