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.

Pertussis is a pediatric infectious disease with one of the highest degrees of infectivity. Although pertussis may cause asymptomatic infections in children and adults with immunity, it can cause life-threatening diseases in newborn babies or infants. We report three cases of pertussis in infants <3 months of age without DTaP immunization who have received symptomatic treatment with the diagnosis of bronchiolitis from other hospitals, and subsequently correctly diagnosed and treated. The patients did not have the characteristic whooping cough, but the main symptoms were episodic cough, intermittent vomiting, and cyanosis. Based on culture results for Bordetella pertussis and PCR, pertussis was diagnosed and treated without any complications. As it is assumed that adults, adolescents, and asymptomatic patients may serve as sources of infection, immunization with Tdap vaccine is recommended to prevent dissemination of pertussis from adolescents and adults to infants, and thus maintain herd immunity.

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.

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

PURPOSE: 1) to construct cohorts according to risk scores calculated with the Gail Breast Cancer Risk Assessment Tool (Gail et al., 1989) (Gail) and the Breast Cancer Risk Appraisal (Lee et al,. 2003) (Lee) 2) to identify the distribution of risk factors and preventive behavior stages between the cohorts 3) to identify abnormal breast conditions in risk cohort. METHOD: Using convenience sampling, 775 rural women were selected. Risk appraisal was scored using Gail and Lee. Preventive behavior stages for BSE (Breast self examination) and mammography were measured using 4 stages of the Transtheoretical Model (Prochaska & DiClemente, 1983). RESULTS: 1) The risk cohort according to Gail was 12.3% (n=95), and Lee, 3.1% (n=24). 2) There were significant differences in the distribution of risk factors (age, family history, age at 1st live birth, age at menarche, number of breast biopsy, history of breast disease, and breast-feeding) between cohorts. 3) There was a significant difference in the distribution of the stage of BSE according to Lee. 4) Six women in the risk group detected masses or nodules and physician consultation and ultrasonography were recommended. CONCLUSION: On the basis of the constructed cohorts, further longitudinal studies of cohorts are recommended with interventions according to characteristics of cohorts.

Adenoid cystic carcinoma (ACC) is a rare variant of adenocarcinoma that usually occurs in the major salivary gland. In breast, adenoid cystic carcinoma is a very rare carcinoma accounting for less than 1% of the all breast carcinoma. It has an excellent prognosis with the lower incidence of distant metastasis and axillary lymph node involvement, and a benign looking or low suspicious findings on imaging. We will report the radiologic and pathologic finding of the adenoid cystic carcinoma that is incidentally detected in the right breast of asymptomatic 47-year-old woman, who had taken annual screening mammogram and ultrasonogram.

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.

The purpose of this study was to investigate the influence of regular stretching exercise for 1 year on health related fitness of the elderly women. We also determined whether the weekly stretching exercise sessions followed by intensive stretching exercise program was beneficial to maintain the altered health related fitness status. The thirty elderly women (F, 80.1+/-6.6 yr) were participated in this study. Subjects had no serious orthopedic problems. During the study period, they did not perform any regular physical activity beside the stretching exercise. The 1 year stretching exercise programs included 3 days/week stretching exercise session for the first 12 weeks followed by 1 day/week stretching exercise for rest of the study period. The subjects were tested 6 categories of health related fitness factors which included % body fat, flexibility, hand grips, back strength, balance, and agility. The summary of the results of this study were as followed: 1) There were significant increase in FFM and slightly decrease in %BF and WHR after the 3 days/wk stretching exercise program. However, there were significant decrease in FFM and WHR after the 1 day/wk stretching exercise program (p<.05). 2) There were significant increase in flexibility, hand grip strength (Rt.) and balance after the 3 days/wk stretching exercise (p<.05) while hand grip strength (Lt.) and back strength were slightly increase after the exercise. However, there were significant decrease in hand grip strength (both) and reaction time after 1 day/wk stretching exercise program while flexibility, back strength, and balance were slighly decrease after the program. In conclusion, this study showed that the 3 days/wk stretching exercise for 12 weeks result in significant increase of all health related fitness factors (p<.05). However, it showed that some of the HRF factors were decreased after the weekly stretching exercise unexpectedly.
