Granulocytic sarcoma is a rare localized tumor composed of granulocytic precusor cells. Granu-locytic sarcoma occurs in a variety of clinical conditions and it is often misdiagnosed histologically. Differential diagnosis frorh lymphoma or nonhematopoietic malignancies such as undifferentiated carcinoma or sarcoma is difficult in the routing histologic examination. An evaluation of clinical and histopathologic features was done on 4 cases of granulocytic sarcoma which were diagnosed at Pusan Paik Hospital from 1988 to 1992. During the period, 282 cases of myelogenous leukemia were diagnosed. Immunohistochemical reaction for lysozyme, myelopero-xidase, leukocyte common antigen, epthelial membrane antigen and cytokeratin was assessed comparing to lymphoma and undifferentiated carcinoma. The histologic features of the granulocytic sarcoma revealed thin nuclear membrane, fine chromatin pattern and one or two small nucleoli. It also often involved the vascular wall and infiltrated the native structures without destruction. Immunohistochemical stain revealed that all(4 cases) of granulocytic sarcoma showed diffuse and strong positivity for myeloperoxidase, and partial but strong positivity for lysozyme. One case of granulocytic sarcoma was negative and 3 cases revealed focal positive reaction for LCA, and all 4 cases was negative for cytokeratin and EMA. In summary, careful observation under light microscopy with immunohistochemical stain for myeloperoxidase, lysozyme, and LCA is helpful in the differential diagnosis of granulocytic sarcoma from malignant lymphoma and cytokeratin and EMA is useful for differential diagnosis from undifferentiated carcinoma.

BACKGROUND: Silver has been used for disinfection and sterilization. We aimed to confirm the in-vitro antibacterial effects of nanocrystalline silver-coated gauze. METHODS: Fourteen clinical isolates each of Escherichia coli and Acinetobacter baumannii were used. Bacterial suspensions made in tryptic soy broth were exposed to Ordinary and silver-coated gauze. Bacteria were then harvested from the gauze immediately and after 24 h incubation, cultured on blood agar plates and eunmerated for viable counts. The number of colonies was converted into common logarithms for comparison. RESULTS: The number of colonies recovered from silver-coated gauze was significantly lower than those recovered from ordinary gauze when harvested immediately after exposure (E. coli, 3.06 vs 1.73; A. baumannii, 3.13 vs 1.98; P<0.001). After 24 h incubation of exposed gauze, silver-coated gauze produced less than 1 CFU/mL, whereas ordinary gauze produced a number of colonies significantly higher than it did immediately after exposure (E. coli, 4.13; A. baumannii, 4.46; P<0.001). Conclusion: Compared with ordinary gauze, silver-coated gauze was shown to have 99.99% antibacterial effect.

Purpose: This study aimed to understand and explore the work experiences of Generation Y nurses in hospital organizations. Methods: Participants were nine nurses with generation Y working in the hospital. Data were collected through individual interviews from December 2, 2022 to June 30, 2023. The transcripts were coded and analyzed using Colaizzi's phenomenological method. Results: A total of 33 formulated meanings were derived from the meaningful 50 statements of nine study participants, and then categorized them into 12 themes with a collection of five theme clusters. Conclusion This study found that Generation Y nurses experienced role confusion and physical and mental burden as they caught in the middle in other generations. Even they were wondering whether to continue working as a nurse, which seems that it is crucial to establish a recognition and compensation system to maintain Generation Y nurses in the field. In addition, Generation Y nurses have been found to endure difficult hospital work and demonstrate patience even when working alone, while also deriving strength from their colleagues. Therefore, it is necessary to establish a program for intergenerational harmony among nurses.

The chest radiographs and angiograms were retrospectively evaluated in 47 patients with pulmonary atresia (PA) and ventricular septal defect (VSD) to determine the characteristic findings of major aortopulmonary collateral arteries (MAPCSs) on the chest radiographs. Of 47 patients, 23 had MAPCAs and 24 had only PDA for blood supply of whole right and left lung. Chest radiographs enabled identification of 16 of 23 patients with MAPCAs. The most common finding of MAPCAs was inappropriately large peripheral pulmonary vasculature (n=16, 69.6%). The other findings were tortuosity of pulmonary vasculature (n=12, 52.2%), focal unevendistribution of pulmonary vasculature (n=12, 52.2%), and two descending pulmonary arteries (n=4, 17.4%). When chest radiographs showed two or more findings of MAPCAs, MAPCAs could be differentiated from PDA with statistical significance (p<0.005). It is concluded that chest radiographs may help to identify MAPCAs before angiography if two-dimensional echo ardiography suggests PA with VSD.

PURPOSE: This study was conducted to discover the essence and the structure of the experiences of weight control by nursing students. METHODS: Participants were 12 nursing students who had tried losing weight at C university in Busan, Korea. The data were collected from June 17 to August 6, 2006. For the purpose of this study, focus group discussions and in depth interviews were employed. RESULTS: The collected data were analyzed by using Giorgi's method. As the results of the analysis, the following four components of experience were derived: My appearance looked abnorml; Measures for self-realization; Pursuit of my own way only; Feelings of accomplishment and self confidence. CONCLUSION: It is necessary to develop an effective weight control program with minimized side effects that are harmful to health, based on the components of the nursing students' experiences in weight control that were identified in this study.

PURPOSE: This purpose of this study was to identify the factors related to the health related quality of life among institutionalized elders. METHODS: The subjects were 247 elders institutionalized among one of the four nursing homes in Busan. Data were collected through interview with four standardized questionnaires from August to October, 2008. Questionnaires were related to health related quality of life (SmithKline Beecham's Quality of Life scale, SBQoL), quality of sleep(Pittsburgh Sleep Quality index, PSQI), activity of daily living (Katz ADL Index), and depression (Geriatric Depression Scale Short Form Korea, GDSSF-K). Data were analyzed for descriptive analysis, t-test, one-way ANOVA, Pearson's correlation coefficient, and stepwise multiple regression by using SPSS/WIN 17.0 program. RESULTS: The mean HRQoL in the subjects was 6.62 +/- 0.91. Percentage of the respondents reporting sleep disorders were 72.5% and 27.1% reported being vulnerable to depression. The significant predictors of the HRQoL were sleep quality, activity of daily living (ADL), level of education, and depression. The factors accounted for 28.8% of variance in the health related quality of life of institutionalized elders. CONCLUSION: Sleep quality, activity of daily living, and depression need to be considered as the important control factors for improving the health related quality of life in the institutionalized elders.
