PURPOSE: This study aims to investigate the changes in pulmonary function, gait ability, and quality of life when NMES is applied along with CBE and to provide basic clinical data to be used in pulmonary rehabilitation guidelines for patients with COPD to treat patients with severe COPD. METHODS: For this study, CBE and NMES of quadriceps femoris on both sides were applied to the experimental group (n=10), and only CBE was applied to the control group (n=10). For a pre-test, a 6-minute walk test was performed, and pulmonary function and health-related quality of life were measured. Moreover, an exercise program was applied to each group for 30 minutes per session, 5 times a week, for 6 weeks. After that, a post-test was conducted the same way as the pre-test. RESULTS: In the within-group comparison, there were significant differences in forced expiratory volume in one second, 6-minute walk test and health-related quality of life between the experimental group and the control group (p < 0.01)(p < 0.05). In the between-group comparison, the experimental group showed an increase in forced expiratory volume in one second and 6-minute walk test (p < 0.05) and showed a decline in health-related quality of life (p < 0.05). CONCLUSION: The 6-weeks NMES program improved health-related quality in patients with severe COPD by increasing expiratory volume by reinforcing the function of quadriceps femoris. This finding implies that NMES could be an alternative mode for improving physical functions of patients with severe COPD, who cannot participate in a breathing exercise program or are reluctant to participate.

PURPOSE: The purpose of this study was to evaluate the usefulness of diffusion-weighted imaging (DWI) for the differential diagnosis of various intracranial cystic lesions. MATERIALS AND METHODS: This study included 19 patients (13 males, 6 females) with a mean age of 42.5 years. The final histopathological diagnoses for 14 patients were pyogenic brain abscess (n=3), glioblastoma (n=3), ependymoma (n=1), anaplastic astrocytoma (n=1), pilocytic astrocytoma (n=1), hemangioblastoma (n=2), arachnoid cyst (n=1), epidermoid (n=1) and schwannoma (n=1). The other cases of metastasis (n=4) and arachnoid cyst (n=2) were diagnosed on the basis of clinical, laboratory and imaging data. DWI imaging studies were performed with a 1.5 T MR system. A single shot spin echo EPI pulse sequence was applied. B values were set at 0 and 1000 sec/mm2. The apparent diffusion coefficient (ADC) were calculated from the ADC map of 10 different cystic brain lesions. Conventional MR imaging included T2WI, T1WI, FLAIR and contrast enhanced T1WI. We analyzed the location, nature, signal intensity on DWI, and the enhancement pattern of the lesions. RESULTS: All of the 3 cases of brain abscess, 1 of 4 cases of metastasis and 1 case of epidermoid showed hyperintensity on DWI. The mean ADC value of brain abscess (2 cases) was less than 1.15 (0.13x10-3 mm2/s). The mean ADC values of the other cystic lesions (8 cases) were variable, ranging from 2.840.66 to 3.100.16 (10-3 mm2/sec). CONCLUSION: DWI and ADC values were useful in the differential diagnosis of various intracranial cystic lesions, but some metastatic tumors may mimic a brain abscess on DWI. Therefore, a clinical correlation is mandatory.

BACKGROUND: Most studies on the incidence rate (IR) and post-exposure reporting rate (RR) of needle-stick injuries (NSIs) were performed using retrospective surveillance, which is vulnerable to recall bias. This study aimed to identify the agreement between IRs and RRs obtained from prospective and retrospective surveillance. METHODS: The prospective surveillance was performed with 716 nurses working at 3 hospitals from August to September in 2012. They prospectively reported when they experienced the NSIs, and the investigator retrospectively calculated the RR from records in the infection control unit or health care unit during the same periods when they reported the number of NSIs. The retrospective surveillance was carried out with 312 nurses who participated in the prospective surveillance. They retrospectively answered the question on the number of NSIs and post-exposure reporting after recalling the experienced NSI from August to September in 2012. RESULTS: The IR of NSIs was 9.8 per 100 nurses by the prospective surveillance and 36.4 per 100 nurses by the retrospective surveillance, which was statistically significantly different (P<0.001). The RR of NSIs was 14.3% by the prospective surveillance and 8.5% by the retrospective surveillance, which was not statistically significantly different. CONCLUSION: We recommend using a prospective approach for calculating the IR of NSIs to reduce the risk of recall bias. However, the RR of NSIs can be calculated using both prospective and retrospective approaches.

Persistent sciatic artery (PSA) is a continuation of the internal iliac artery into the popliteal-tibial vessels and this structure provides the major blood supply to the lower limb bud during early embyrologic development, Its remnants participate in the formation of the inferior gluteal, deep femoral, popliteal, peroneal and pedal vessels. When the femoral artery develops, the PSA then involutes. In rare circumstances it persists and so provides the only major blood supply to the lower limb. The PSA was first reported by Green in 1832 and until now, only about 100 cases have been reported in the world literatures. This rare vascular anomaly is associated with aneurysmal formation in 15% to 46% of cases and it has a bilateral location in 22% of PSA cases. In more than 40% of cases, PSA is asymptomatic. When present, such non-specific symptoms as gluteal pain and painful buttock mass are presented. However, the most frequent clinical finding is lower limb ischemia because in 25% of such cases, the presented symptoms are limb threatening. We describe here the case of a 54 year-old female affected with PSA occlusion, and she was treated with a combination of thrombolysis and thromboembolectomy.

OBJECTIVES: The purpose of this study was to evaluate the effects of emotional labor on burnout, turnover intention, and job satisfaction. METHODS: Dental hygienists were surveyed over a period of 13 days during March, 2013. Data from the completed questionnaires (N=202) were analyzed using the t-test, one-way ANOVA, Pearson's correlation, and hierarchical multiple regression. RESULTS: Higher levels of emotional labor resulted in higher levels of burnout and turnover intention, as well as lower levels of job satisfaction. The variable showing the largest mediating effect between emotional labor and burnout was emotional intelligence. Supervisor support had the largest mediating effect between emotional labor and turnover intention, as well as emotional labor and job satisfaction. CONCLUSIONS: To reduce the negative effects caused by emotional labor, it is necessary to foster the development of emotional intelligence and self-efficacy of employees. Employers' efforts to improve supervisor and colleague support for the employees should be made to reduce such negative effects.

OBJECTIVE: The aim of this study is to review 6 years' experience of peritoneal inclusion cysts at our hospital. METHODS: A retrospective study of 13 cases of peritoneal inclusion cysts between Jan. 1, 1996 and Dec. 31, 2001 was carried out and then clinical feature, radiologic finding, and treatment method were compared with previous reports. RESULTS: Most of patients were premenopausal. Chief complaints were lower abdominal pain or palpable abdominal mass, and so forth. The majority of patients had history of lapalotomy. Peritoneal inclusion cyst was diagnosed by ultrasonogrphy and CT. Most specific finding is that normal ovary is seen in the cysts. In the past, operation was the main treatment method. Recently sclerotherapy was introduced and available. CONCLUSION: Because peritoneal inclusion cyst is benign and uncommon disease, it had not been interesting part. So, preoperative diagnosis rate was low and surgical resection was main treatment method. Preoperative diagnosis rate has been higher after it's clinical feature and specific radiologic findings were reported. Recently, conservative treatment may substitute for operation.
