Desmoplastic fibromas are rare intraosseous bone tumors. They are benign but locally aggressive and frequently found in the long bones and mandible. We report radiographic and histopathologic finding of a case desmoplastic fibroma involving right temporal skull bone. A 53-year-old woman presented at our hospital complaining of continuous right side headaches for a year. Simple skull X-ray film showed 3 x 2.5 cm lytic lesion with mild sclerotic margin on right temporal area. A large craniectomy 1cm lateral to margin was fashioned. The resected mass showed encapsulated mass colored white gray. Histologic diagnosis was compatible with that of a the desmoplastic fibroma. There was no evidence of recurrence during the 15months of follow-up period.

Malignant epithelial neoplasm usually occurs in postmenopausal women, with less than 10% of cases occurring in women under the age of 20. In patients below this age, the majority of ovarian tumors are of germ cell origin and malignant ovarian epithelial tumors are uncommon. We report US & CT imaging in a case of mucinous cystadenocarcinoma in a 17-year-old nullipara who complained of amenorrhea for 45 days and a palpable mass.

PUPPOSE: The purpose of this study was to analyze related factors for major nursing diagnoses used in caring for institutionalized elders. METHOD: This study was a descriptive study. The participants were 92 residents in a long-term care facility in Wonju, selected by convenience sampling. The instrument was a checklist designed on the basis of the related factors suggested by NANDA (1997) and a literature review. Data was collected by chart review, observation, and interviews with the participants. Data was analyzed using descriptive statistics with the SPSS WIN program. RESULT: The most frequent nursing diagnosis was 'risk for injury', 'self-esteem disturbance', 'activity intolerance', 'impaired phyical mobility', and 'powerlessness'. The most frequent component for related factors for the five component for each nursing diagnosis was the physical component, followed by the social component. Common related factors for the nursing diagnoses were 'pain', 'change of emotional state/disorder', 'cognitive disorder', 'change of physical structure and function', and 'physical impairment', and 'immobility'. CONCLUSION: The results of this study can contribute to the development of appropriate nursing intervention programs for elders (eg. 'Injury Prevention Programs', 'Self-esteem Improvement Programs' etc.). Clinical guidelines that gerontological nurses can use to accurately assess health problems and select appropriate nursing interventions may be developed.

PURPOSE: The purpose of this study was to identify experiences of nurses who served as preceptors in clinical education for senior student nurses in a college of medicine in Wonju city. METHOD: Data was collected from 20 preceptors instructing senior student nurses in 2001 using a self-completion questionnaire. To analyze data, content analysis was done using an analysis scheme developed by the investigators. RESULT: The analysis scheme consisted of 7 categories and 25 subcategories. 135 significant statements were analyzed and categorized. Preceptors indicated that they were role models, socialization facilitators and educators while instructing students in the clinical practicum. In performing the preceptors' role, preceptors reported that their most important change was self-enhancement,and positive experience was a constructive work atmosphere. The most important factor facilitating the preceptors' role performance was support from head nurses, and the most discouraging factor was work loads. CONCLUSION: This study suggests that interventions for encouragement and socialization of preceptors should be developed to promote clinical education for senior student nurses.

Thymoma is a rare neoplasm associated with a number of autoimmune disorders and tumors. Organizing pneumonia is a reaction of the lung to various injuries. A feature of organizing pneumonia is plugs of granulation tissue within the lumens of small airways, or alveoli. Causes of organizing pneumonia include various disorders and conditions; however, thymoma with organizing pneumonia located in both lungs is very rare. We report a case of resolving organizing pneumonia after thymoma resection. Our case is the first to demonstrate that resolving organizing pneumonia can occur after thymoma resection, as has been speculated by many researchers.

PURPOSE: The purpose of this study was to identify the theoretical characteristics and direction of inquiry in the discipline of nursing by analyzing doctoral dissertations. METHOD: The materials used in this study were 277 doctoral dissertations from five universities in Korea. The framework for the study was derived from Kim's(1993) alternative linkage among philosophy, theory, and method in nursing science. RESULT: Of the 277 dissertations it was found that there were 13 types of linkages out of a possible 54 types. Most of the dissertations (128 of 277) were done within the linkage of realism/etic/quantitative/explanatory knowledge type. Of the 218 dissertations within scientific realism, 42 were within relativism, and 17 within practicism. There were 134 dissertations of the explanatory knowledge type, 112 descriptive ones, and 31 prescriptive ones. Studies done within the etic quantitative methodology included 209 dissertations and within the emic perspective, 43 with qualitative methodology, and 7 with quantitative. CONCLUSION: The results show that it is necessary to develop more alternative linkages for nursing practice and this will lead to expanding nursing knowledge.

BACKGROUND: Biomarkers for cancer have several potential clinical uses, including the following: early cancer detection, monitoring for recurrence prognostication, and risk stratification. However, no biomarker has been shown to have adequate sensitivity and specificity. Many investigators have tried to validate biomarkers for the early detection and recurrence of lung cancer. To evaluate plasma G-CSF as such a biomarker, protein levels were measured and were found to correlate with the clinicopathological features of primary lung tumors. METHODS: Between December 2006 and May 2008, 100 patients with histologically-validated primary lung cancer were enrolled into this study. To serve as controls, 127 healthy volunteers were enrolled into this study. Plasma G-CSF levels were measured in lung cancer patients using the sandwich ELISA system (R & D inc.) prior to treatment. RESULTS: The mean plasma G-CSF levels were 12.2+/-0.3 pg/mL and 46.0+/-3.8 pg/mL (mean+/-SE) in the normal and in the cancer groups, respectively. In addition, plasma G-CSF levels were higher in patients with early lung cancer than in healthy volunteers (p<.001). Plasma G-CSF levels were higher in patients who were under 65 years old or smokers. Within the cancer group, plasma G-CSF levels were higher in patients with non small cell lung cancer than in patients with small cell lung cancer (p<.05). Overall, plasma G-CSF levels were shown to increase dependent upon the type of lung cancer diagnsosed. In the order from highest to lowest, the levels of plasma G-CSF tended to decrease in the following order: large cell carcinoma, squamous cell carcinoma, adenocarcinoma, and bronchioloalveolar carcinoma. Plasma G-CSF levels tended to be higher in patients with advanced TNM stage than in localized TNM stage (I, II Adenocarcinoma ; Adenocarcinoma, Bronchiolo-Alveolar ; Adrenal Glands ; Biomarkers ; Carcinoma, Large Cell ; Carcinoma, Squamous Cell ; Enzyme-Linked Immunosorbent Assay ; Granulocyte Colony-Stimulating Factor ; Humans ; Lung ; Lung Neoplasms ; Neoplasm Metastasis ; Plasma ; Recurrence ; Research Personnel ; Small Cell Lung Carcinoma

BACKGROUND: Autophagy is an important adaptive mechanism in normal development and in response to changing environmental stimuli in cancer. Previous papers have reported that different types of cancer underwent autophagy to obtain amino acids as energy source of dying cells in nutrient-deprived conditions. However, whether or not autophagy in the process of lung cancer causes death or survival is controversial. Therefore in this study, we investigated whether nutrient deprivation induces autophagy in human H460 lung cancer cells. METHODS: H460, lung cancer cells were incubated in RPMI 1640 medium, and the starved media, which are BME and RPMI media without serum, including 2-deoxyl-D-glucose according to time dependence. To evaluate the viability and find out the mechanism of cell death under nutrient-deprived conditions, the MTT assay and flow cytometry were done and analyzed the apoptotic and autophagic related proteins. It is also measured the development of acidic vascular organelles by acridine orange. RESULTS: The nutrient-deprived cancer cell is relatively sensitive to cell death rather than normal nutrition. Massive cytoplasmic vacuolization was seen under nutrient-deprived conditions. Autophagic vacuoles were visible at approximately 12 h and as time ran out, vacuoles became larger and denser with the increasing number of vacuoles. In addition, the proportion of acridine orange stain-positive cells increased according to time dependence. Localization of GFP-LC3 in cytoplasm and expression of LC-3II and Beclin 1 were increased according to time dependence on nutrient-deprived cells. CONCLUSION: Nutrient deprivation induces cell death through autophagy in H460 lung cancer cells.

BACKGROUND: Most lung cancer patients receive systemic chemotherapy at an advanced stage disease. Cisplatin-based chemotherapy is the main regimen for treating advanced lung cancer. Recently, autophagy has become an important mechanism of cellular adaptation under starvation or cell oxidative stress. The purpose of this study was to determine whether or not autophagy can occurred in cisplatin-treated lung cancer cells. METHODS: H460 cells were incubated with RPMI 1640 and treated in 5 micrometer or 20 micrometer cisplatin concentrations at specific time intervals. Cells surviving cisplatin treatment were measured and compared using an MTT cell viability assay to cells that underwent apoptosis with autophagy by nuclear staining, apoptotic or autophagic related proteins, and autophagic vacuoles. The development of acidic vascular organelles was using acridine orange staining and fluorescent expression of GFP-LC3 protein in its transfected cells was observed to evaluate autophagy. RESULTS: Lung cancer cells treated with 5 micrometer cisplatin-treated were less sensitive to cell death than 20 micrometer cisplatin-treated cells in a time-dependent manner. Nuclear fragmentation at 5 micrometer was not detected, even though it was discovered at 20 micrometer. Poly (ADP-ribose) polymerase cleavages were not detected in 5 micrometer within 24 hours. Massive vacuolization in the cytoplasm of 5 micrometer treated cells were observed. Acridine orange stain-positive cells was increased according in time-dependence manner. The autophagosome-incorporated LC3 II protein expression was increased in 5 micrometer treated cells, but was not detected in 20 micrometer treated cells. The expression of GFP-LC3 were increased in 5 micrometer treated cells in a time-dependent manner. CONCLUSION: The induction of autophagy occurred in 5 micrometer dose of cisplatin-treated lung cancer cells.
