PURPOSE: Misdiagnosed breast cancer on screening mammography was retrospectively reviewed in an attempt to analyze the cause for the undiscovery and to determine findings that might have been suggested on the mammographic examination. MATERIALS AND METHODS: Of the 173 breast cancers that were pathologically proven, 17 breast cancers misdiagnosed on mammogram was retrospectively analyzed for the causes of the misinterpretation and predominant secondary findings. RESULTS: Three of the 17 were negative on mammography except for dense breast. Two patients had localized asymmetricity without visible mass. Ten patients had benign-looking mass which was well-defined (n=5), partially defined(n=2), multiple (n=l), or included benign-looking calcifications(n=2). Remaining two cases were retrospectively diagnosed as misinterpreted breast cancers. Various secondary findings such as were useful in the diagnosis of breast cancer. CONCLUSION: Meticulous observation could improve the diagnostic yield of breast cancer in mammography.

BACKGROUND: Nonalcoholic fatty liver disease (NAFLD) is associated with metabolic syndrome including insulin resistance, hypertension, dyslipidemia, central obesity, type 2 diabetes, and cardiovascular disease. In NAFLD, insulin resistance plays an important role in the progression of liver damage. In this study, we evaluated insulin resistance, plasma adiponectin, hepatic steatosis, and their association in adults with normal liver transaminase concentrations. METHODS: We analyzed 111 subjects, aged over 20 years old, who visited the Health Management Center at Chung-Ang University Hospital between May 2006 and August 2006. They had neither history nor clinical evidence of diabetes, cardiovascular or liver disease. They were divided into three groups by the degree of hepatic steatosis based on ultrasound findings. Anthropometric parameters were measured and blood samples were drawn after eight hours of fasting. RESULTS: Hepatic steatosis had a positive correlation with body mass index, waist circumference, blood pressure, triglycerides, HOMA-IR, and QUICKI. Moreover, it had a negative correlation with high-density lipoprotein cholesterol and adiponectin. Triglycerides, Adiponectin, and QUICKI were independent variables in predicting the degree of hepatic steatosis. CONCLUSION: This finding suggests that triglycerides and plasma adiponectin are independent predictors of hepatic steatosis in adults with normal liver transaminase concentrations.

Submerged implants require secondary surgical uncovering of implants after healing period of 3 - 6 months. In surgical methods, there are surgical scalpel, tissue punch, electro-surgical, and laser-used uncovering, and laser-used uncovering, and so forth. The objectives of this study are investigation and assessment of 1) thermal change in clinical application for uncovering of HA-coated implant and pure titanium implant irradiated by pulsed Nd-YAG. CO2, and Er-YAG laser. 2) surface change of cover screws after irradiation using laser energy. The temperature of apex & side wall of implants were recorded at 10sec, 20sec, 30sec after 30sec irradiation to implant healing screw; 1) pulsed Nd-YAG laser; 2W, 20pps, contact mode 2) CO2 laser; water-infused & non-water infused state, 2.5-3.5W, contibuous mode, noncontact mode 3) CO2 laser; non-water-infused state, 3W, superpulse, noncontact mode 4) Er-YAG laser; (1) non-water infused state, 10pps, 60mj, contact mode (2) water-infused state, 10pps, 60mj, 80mj, 101mj, contact mode According to the results of this study, pulsed Nd-YAG laser is not indicated because of increase thermal change and pitting of metal surface of implant cover screw. By contrast, CO2 laser & Er-YAG laser are presumed to indicate because of narrow range of thermal change & near abscence of thermal damage of metal surface. Dental laser is thought to be much helpful to surgical procedure when it is used as optimal power and time condition considering characteristics and indications of each laser. Further research is needed to verify that these techniques are safe and beneficial to implant success.

Mixed tumor of the skin (chondroid syringoma) is a rare benign tumor composed of epithelial elements intermingled with myxoid or cartilagenous stroma which is not separated by basement membrane. It had been believed to originate from the eccrine gland but recently, it was described to be of apocrine gland origin in case of showing apparent apocrine secretion. We report on a 63-year-old man with a tumor on the right upper eyelid showing typical microscopic features of mixed tumor of the skin. Many apocrine decapitation secretions were seen in tubular structures and follicular differentiations were also seen, which represents the common origin of folliculo-sebaceous-apocrine unit.

Blue nevus is a benign melanocytic neoplasm and represents itself usually as a solitary blue or blue-black papule. It rarely occurs as multiple lesions grouped in a circumscribed area. How-ever, non-grouped disseminated blue nevi are exceedingly rare. We report a patient with acquired multiple blue nevi that was distributed over the entire body discretely and showed an increase in the number of the nevi without any causal factors.

From January 1995 to December 1997, a total of 219 cases pelviscopic surgery was performed at Il Sin Christian Hospital. To evaluate the safty and efficacy of pelviscopic surgery, we reviewed indication of operation, mean age, parity, history of abdominal operation, type of operation, duration of hospitalization and complication retrospectively. The number of pelviscopic surgery have risen from 33 cases in 1995 to 53 cases in 1996 and 133 cases in 1997. The most common indications were 118 cases for ectopic pregnancy (53.9%) and 42 cases for ovarian cyst (19.2%), 20 cases for infertility (9.1%) in order. Among the ovarian cyst, endometrioma was the most common. The mean age of patients was 31+/-6.7 years old and mean parity was 0.77. In most cases, mean blood loss was lesser than 100 cc except 500 cc in LAVH, 150 cc in CISH, 106.7 cc in ectopic mass removal. The postoperative hospital stay was varied from 0 day to 10 days, but usually 2 days. The 26 cases had complicated and the most common complication was fever above 38degrees C. In conclusion, it is evident that pelviscopic surgery is lesser invasive technique, has lower complication rate and shorter the length of hospitalization. So, we expect the number and indication of pelviscopic surgery will be increased in future.

The purpose of this study was to explore the change of muscle strength, muscle endurance, flexibility and activities of daily living to develop a rehabilitational program. The subjects were selected randomly among the patients who underwent kidney transplantations at one major transplantation hospital in Seoul, Korea. This study was carried out between November 23, 1999 and February 15, 2000. The subjects in this study consisted of 16 patients who had kidney transplantations between 1 month and 12 months ago prior to this study. They were all on steroids and did not take any physical exercise regularly. The muscle strength, muscle endurance, flexibility and activities of daily living were evaluated at 1st week and after 12 weeks. The data were analyzed with numbers, percentiles, mean, standard deviation and t-test. The results were as follows: 1. After 12 weeks, the grip strength was significantly decreased than 1st week (p=.0002). 2. After 12 weeks, the back lift strength was significantly decreased than 1st week (p=.0002). 3. After 12 weeks, the muscle endurance was increased than 1st week, but it was not significant(p=.5487). After 12 weeks, the flexibility was significantly decreased than 1st week (p=.0002). 5. After 12 weeks, the activities of daily living was significantly decreased than 1st week (p=.0006). Like the above result, the kidney transplant receipients' muscle strength, flexibility and activities of daily living were reduced. In order to solve this problem, the writer has found that program development to prevent the defects should be extremely required. Since now on the number of patients should expand. After the kidney transplantation, the periods of 4, 8, 12 and 16 weeks are extended. The writer proposes to examine the different phase of change in each periods.

PURPOSE: This study aimed to investigate job satisfaction, organizational commitment and turnover intention among male nurses in South Korea. METHODS: Data were collected in May, 2013 and a total of 150 male hospital nurses participated in this study. Job satisfaction, organizational commitment and turnover intention were measured using a structured questionnaire. Collected data were analyzed using SPSS/WIN 20.0 for windows. RESULTS: There were statistically significant correlations between job satisfaction and organizational commitment (r=.74, p<.001), job satisfaction and turnover intention (r=-.56, p<.001), and organizational commitment and turnover intention (r=-.69, p< .001). There was a statistically significant difference in job satisfaction of participants according to education, work unit, and salary. Organizational commitment showed significant difference according to age, education, work unit, and salary. Turnover intention was significantly different according to duration of employment in the hospital, and salary. The most influential factor for turnover intention was organizational commitment (beta=-.69, p<.001). This factor accounted for 47.8% of the variance in turnover intention. CONCLUSION: The results of this study indicate that to reduce turnover intention for men in nursing, it is necessary to increase job satisfaction, and organizational commitment.
