Cystic lymphangioma are rare benign tumors that originate as a congenital anomaly of the lymphatic system. Their common presentation is in neck and axillary area at the birth, during infancy or early pediatric age group. Author reports an unusual case of cystic lymphangioma of breast which was diagnosed in a 32-year-old woman. The findings were very dense, sharply defined, and multilobulated masses on mammography, and mu-Itiloculated echo free lesions on ultrasonogram.

We report two cases of recurrent extramarnmary Pagets disease after wide local excision. Both cases involved the scrotum and the penoserotal junction, respectively. On histopathological examination, we could observed many Paget cells confined to the epidermis and the hair follicle, but not invading the underlying dermis in both cases. There was no evidence of internal malignancy. Both cases were treated with wide local reexcision.

Malignant neoplasm associated with chronic empyema is rare. Most squamous cell carcinomas of the pleura may occur in association with chronic persistent empyema, with or without pleurocutaneous fistula. We report a case of squamous cell carcinoma associated with chronic empyema caused by a metallic foreign body.

PURPOSE: The purpose of this study was to investigate the status of infection control in long-term care facilities in Korea and educational needs of nurses in charge of infection control. METHODS: This was a descriptive study. A self-reported questionnaire was provided to the nurses in charge of infection control in 250 hospitals with long-term care. 209 nurses answered to the questionnaire. Data were collected from September 30 to November 7, 2016. Data were analyzed using SPSS/WIN 18.0, and the educational needs were analyzed by applying the Borich Needs Assessment Model. RESULTS: Only 17.4% of the hospitals had infection control departments, and only 1.0% of the hospitals had nurses who were fully-in-charge of infection control. Regarding the educational needs on infection control, level of knowledge was statistically significantly lower in all 50 items compared to the importance. Specifically, educational demand on air and water quality management, construction and infection control, indicator management, and infectious disease management were also high. CONCLUSION: The results of this study showed that organization and manpower were needed for effective infection control of long-term care facilities in Korea. In addition, it was deemed necessary to develop and applicate infection control education programs as reflected on the scores obtained in the educational needs on infection control.

OBJECTIVE: To compare the reliability of the Greulich-Pyle (GP) method, Tanner-Whitehouse 3 (TW3) method and Korean standard bone age chart (KS) in the evaluation of bone age of prepubertal healthy Korean children. MATERIALS AND METHODS: Left hand-wrist radiographs of 212 prepubertal healthy Korean children aged 7 to 12 years, obtained for the evaluation of the traumatic injury in emergency department, were analyzed by two observers. Bone age was estimated using the GP method, TW3 method and KS, and was calculated in months. The correlation between bone age measured by each method and chronological age of each child was analyzed using Pearson correlation coefficient, scatterplot. The three methods were compared using one-way analysis of variance. RESULTS: Significant correlations were found between chronological age and bone age estimated by all three methods in whole group and in each gender (R2 ranged from 0.87 to 0.9, p < 0.01). Although bone age estimated by KS was slightly closer to chronological age than those estimated by the GP and TW3 methods, the difference between three methods was not statistically significant (p > 0.01). CONCLUSION: The KS, GP, and TW3 methods show good reliability in the evaluation of bone age of prepubertal healthy Korean children without significant difference between them. Any are useful for evaluation of bone age in prepubertal healthy Korean children.

Mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episode (MELAS) syndrome is a maternally inherited mitochondrial disorder that usually affects the cerebral cortex and prevents high-energy demands from being met. Herein, we present the case of a male patient who rapidly developed multiple seizures, headaches, and altered mentality accompanied by severe metabolic acidosis and lactic acidosis. Initially, a brain imaging study confirmed stroke-like lesions (SLLs) only in the cerebellum. During follow-up, newly developed SLLs with lactic acidosis were observed in the basal ganglia (BG), cerebellum, and occipital lobe. The m.3243A>G variant had been found in the patient and MELAS was diagnosed, despite the BG and cerebellum being atypical locations for SLLs in MELAS. Since most cases of m.3243A>G variant MELAS show SLLs in the cerebral cortex, this case is unusual considering the location of the lesion. We emphasize that in the case of lactic acidosis accompanied by neurological symptoms, such as seizures, as in this case, MELAS should be included in the differential diagnosis, even if SLLs are observed in areas other than the cerebral cortex.

Bednar tumor was described by Bednar in 1957. The histologic pattern of this tumor shows similar to dermatofibrosarcoma protuberans (DFSP) but melanin pigments are scattered within the tumor, It's rare neoplasm accounting for approximately 1-5% of all case of DFSP. Clinically, this tumor is considered to be intermediated malignancy, because of slow growth and frequent local recurrence and lack of distant metastasis. The majority are located on the trunk and the upper and lower extremities, but extremely rate in the head and neck area. Microscopically, this tumor is characterized by tight storiform spindle cells and long slender cells that admixed with a small population of melanin containing dendritic cells. This dendritic cells are the primary features distinguising this lesion from conventional DFSP. Complete surgical excision and close follow-up case are necessany for this neoplasm because of probable intermediate malignancy. A patient was admitted to Our Department of Oral and Maxillofacial Surgery due to swelling on right parotid area and numbness of the right lower lip on September, 1994, By clinical examinations and C-T finding, we dignosed tentatively as myxoma or pleomorphic adenoma. Surgical excision of this tumor was performed with parotidectomy and mandibular osteotomy under the frozen biopsy. By final microscopic and electromicroscopic examination and immunohistochemical study, this tumor was diagnosed as Bednar tumor. So, we report a case of pigmented DFSP with review of literatures.

OBJECTIVES: Healthy sleep is important and can have a positive effect on resilience. The aim of the present study was to compare the differences in resilience between two group nurses in rotating shift and daytime fixed work schedules and to investigate stress perception, coping factors, social and psychological health, and sleep factors that may affect resilience. METHODS: A total of 400 female nurses having rotating shift and daytime fixed work schedules at two hospitals was surveyed from June 12, 2017 to June 12, 2018. All participants completed perceived stress scale (PSS), stress coping short form (Brief COPE), psycho-social wellbeing Index short form (PWI-SF) or general health questionnaire-18 (GHQ-18), center for epidemiologic studies depression scale (CES-D), STAI-X-1 in state-trait anxiety inventory (STAI), Pittsburgh sleep quality index (PSQI), Epworth sleepiness scale (ESS), insomnia severity index (ISI), Conner Davidson resilience scale (CD-RISC). Independent t-test, paired t-test, Pearson correlation analysis, and multiple regression analysis were applied to the results of the final 373 questionnaires of 400 nurses in two general hospitals. RESULTS: Comparing the variable statistics between the two groups of rotating shift and daytime fixed work nurses, showed statistically significant differences in all variables except perceived stress, sleep quality, and daytime sleepiness. Factors that had a significant correlation with resilience were stress coping strategies, depression, and insomnia severity (p < 0.001). In multiple regression analysis, larger positive reframing1 (β = 0.206, p < 0.001), severe less depression (β = −3.45, p < 0.001), and higher psychosocial health (β = 0.193, p < 0.001). As acceptance coping2 increased (β = 0.129, p < 0.05), as daytime sleepiness decreased (β = −1.17, p < 0.05), and as active coping2 increased (β = 0.118, p < 0.05), as the positive reframing2 increases (β = 0.110, p < 0.05), the resilience increased. CONCLUSION This study, it was found that resilience was higher in daytime fixed workers than in shift workers. In addition, specific stress coping strategies, psycho-social health, sleep, and depression factors were associated with resilience.
