Accessory ovaries are rare entities defined as small portions of ovarian tissue situated near, and connected to, the normally placed ovary. Tumors arising in accessory ovaries are extremely rare. In particular, a fibroma arising from an accessory ovary has not been reported in the literature. We describe such a case with a fibroma developing in an accessory ovary. A 53-year-old multiparous woman presented with abdominal pain for 2 months. Pelvic computed tomography revealed 11.0x8.0x6.0 cm sized cystic mass with a thick septal wall in right adnexa. The preoperative diagnosis was a borderline ovarian tumor. Furthermore, a laparotomy showed a cystic mass connected to the right ovary by stalk. The bilateral eutopic ovaries were completely normal. Histologically, an accessory ovary was replaced by a fibroma accompanied by extensive cystic change.

This study was prospectively conducted to investigate any relationship of nutritional status at the time of admission to length of hospital stay and mortality. All patients admitted to the Asan Medical Center between October 13 and November 12, 1997 who met the study criteria were included in the study. Patients were classified as Not-at-risk, At-risk I or At-risk II based on the levels of serum albumin and total lymphocyte count in a computerized nutrition screening program. Sixty three percent of the patients were classified as Not-at-risk Group, 29% as At-risk Group I and 8% as At-risk Group II. Significant correlation was observed between nutritional status and LOS (P<0.01) as well as mortality rate (P<0.05). The more the patient had the nutritional risk factors, the longer the LOS and the higher the mortality rate were. Further studies have to be done in order to demonstrate cost-effectiveness of medical therapy for the malnourished hospitalized patients.

Angiomyolipoma of the liver is a rare benign tumor that's composed of variable mixtures of adipose tissue, smooth muscle and thick-walled blood vessels. We report here on the imprint cytologic features of a hepatic angiomyolipoma in a 47-year-old man. The smears showed spindle and epithelioid tumor cells in clusters, trabeculae and single cells. The spindle cells had elongated, cigar-shaped nuclei with finely granular chromatin and fibrillary cytoplasm. The epithelioid cells had round nuclei with a moderate amount of cytoplasm. Any adipose tissue was not found. Immunohistochemically, both the spindle and epithelioid cells revealed cytoplasmic positivity for smooth muscle actin and HMB-45.

This study investigated the mechanical properties and antibacterial activity of glass ionomer cement (GIC) containing 1 mol% or 5 mol% gallium phosphate glass (GPG) powder. GPG were added to conventional GIC powder in a range of 0~20 wt%. The specimens for compressive strength (4 mmØ×6 mm) and diametral tensile strength (6 mmØ×4 mm) were prepared by mixing with the cement liquid and kept in an water of 37±1℃. Mechanical properties were evaluated at an interval of 1 h, 24 h, and 7 days. Antibacterial activity of specimens against to S. mutans and S. sobrinus was evaluated using agar diffusion methods. Data were statistically analyzed by one-way ANOVA and Tukey HSD post-hoc test (p<0.05). Diametral tensile strength of GIC containing GPG were significantly higher than control GIC while compressive strength showed no statistical difference. There was an increasing tendency of antibacterial activity for GPG-GICs. Results indicated that GPG can be considered as potential reinforcing agent for increasing antibacterial and mechanical properties for conventional GIC.

PURPOSE: For this study an examination was done of relationships between intensive care unit (ICU) nurses' knowledge related to sedation and their clinical competencies in sedation practice. METHODS: Ninety one ICU nurses were recruited from two tertiary hospitals in South Korea. A self-report questionnaire was used to examine the levels of knowledge related to sedation and nursing practice competence based on Ajzen's theory of planned behavior. Descriptive statistics, independent t-tests, one-way ANOVA, and Pearson correlations were performed using the IBM SPSS 21.0 RESULTS: ICU nurses are more knowledgeable about general information on sedation rather than up-to-date information. Continuing education on sedation was related to difference in knowledge levels. However, the levels of knowledge were not related to competence in sedation practice. Instead, a positive attitude toward sedation practice was significantly related to the subjective norms; orders and goals, perceived behavioral control, practice of sedation, and intention to use. CONCLUSION: The results of this study provide fundamental information on levels of knowledge related to sedation practices of Korean ICU nurses. Continuing education should emphasize up-to-date information on sedation practice and need for positive attitudes which influence all other competencies towards sedation practices to achieve optical care of sedation in the ICU.

PURPOSE: This study tries to identify experience of verbal abuse, emotional response, and ways to deal with verbal abuse against nurses in hospitals. METHODS: This study was a descriptive research and conducted from April to July 2011. One hundred and seventeen nurses with over one-year experience in general wards were selected and evaluated. The data were analyzed using descriptive analysis, independent t-tests, and one-way ANOVA. RESULTS: The nurses' experience rate of verbal abuse during the entire period of work in hospitals was 98.3%. The majority of the nurses were verbally abused by patients (70.9%), followed by patients' relatives (65.8%), physicians (61.5%), and coworkers (58.1%). Overall negative emotional response score of nurses after verbal abuse was 38.82+/-8.28. Ways to deal with verbal abuse were as follows: suppression was 74.4%, complaining of an injustice to close people, 67.5%, and ignoring, 43.6%. CONCLUSION: Nurses have significantly been exposed to verbal abuse while working in hospitals. Therefore, hospital managers and nurse managers are required to inform other staff and visitors in hospitals the real condition of verbal abuse against nurses and provide a safe work environment by developing the report and disposal system of verbal abuse.

BACKGROUND: Depression is the leading cause of lowering the quality of life of cancer patients and lung cancer is the most likely to cause depression. It is necessary to find out depression-related factors in lung cancer patients. METHODS: The study was a retrospective cohort study using medical records, and was a non-equivalent comparison group design. It involved patients diagnosed of lung cancer at the Konkuk University Medical Center from January to December 2012. Between antidepressants prescription group and non prescription group, socio-demographic factors, clinical factors, treatment-related factors and other factors were analyzed statistically. RESULTS: Antidepressant prescription group consisted of 23 people and non-prescription group of 206 people. Prescription rate of quetiapine was the highest 47.8% (11/23), followed by escitalopram (43.5%, 10/23), amitryptyline and trazodone (30.4%, 7/23). The prescription group was prescribed with an average of 1.9 antidepressants. Antidepressants were prescribed after average of 248 days from lung cancer diagnosis and prescription period per patient was average 177.5 days. According to the result of univariate logistic regression analysis between 2 groups, factors such as number of outpatient visit, number of admission, days of hospitalization, sleep disorder, and comorbidity were found to be statistically significant (p < 0.05). However, According multivariate logistic regression analysis showed that number of admission, days of hospitalization and sleep disorder were statistically significant (p < 0.05) excluding comorbidity. CONCLUSION: About 10% of lung cancer patients had received a prescription for antidepressants after lung cancer diagnosis. A sleep disorder, number of hospitalization and length of stay were identified as factors influencing the prescribing antidepressants.

PURPOSE: This study was designed to create the job description of Korean transplantation nurse practitioner and examine performance frequencies, criticality, and difficulties of task elements. METHOD: The sample consisted of 63 nurses and coordinators who performed duties related to transplantation at medical center in Korea. A survey method was used, and the questionnaire included frequencies, criticality, and difficulties of task elements in job description by the DACUM method. Using SPSS WIN 10.0, descriptive statistics such as frequency distribution, means, and standard deviations were conducted to examine the subject's general characteristics, the frequencies, criticality, and difficulties of task performance. RESULT: The job description of transplantation nurse practitioners revealed 5 duties, 22 tasks, and 85 task elements. On the all five duties, the averages of the performance frequency, criticality, and difficulty were 2.41, 3.38, and 2.78, meaning that the respondents rarely perform the 5 duties, but consider them critical and easy to perform. CONCLUSION: The job description of the transplantation nurse practitioner included duty, task, and task element and definition of job completed. Thus we recommended a data based trial to confirm and validate the information gathered.

In order to evaluate the cytogenetic hazard among hospital workers potentially exposed to low dose of radiation, the analysis of chromosome aberrations(CA) and sister chromatid exchanges(SCE) in lymphocytes were performed in 79 hospital workers and 79 non-exposed workers. The mean frequency of chromosomal exchange and deletion(respectively, 0.20X10-2/cell and 0.39X10(-2)/cell) in the exposed group were significantly higher than those(0.07X10(-2)/cell and 0.23X10-2/cell) in control group. The frequency of sister chromatid exchanges was 5.04/cell in the control vs. 6.57/cell in the exposed group. There were also significant differences in the mean frequencies of CA and SCE adjusted for age, sex, smoking, drinking between two groups. There were no evidence of significant increase of CA and SCE according to the department or duration of employment. But the frequency of cells having chromosome aberration was significantly higher in the exposed group than in the control group related to duration of employment. There was no dose-effect relationship between the cumulative doses and the frequency of CA and SCE. But in the case of last 1 yr cumulative dose, there were evidence of significant dose-dependant increase of chromosome type CA and percentage of cells with aberration. The result suggest that there is cytogenetic hazard in risk group like hospital workers handling low dose radiation. And the analysis CA and SCE are useful biological indicators for the exposure of low dose level of radiation.
