Polypoid prolapse of mucosal folds can occur at various sites and in various conditions predominantly associated with strain during defecation. There are two well known types of mucosal prolapse syndrome(MPS), the inflammatory cloacogenic polyp(ICP) and the mucosal redundant polyp associated with diverticular disease(N4RPD). ICP is a mucosal prolapse of the anorectal junction and MRPD is a proximal analogue involving the sigmoid colon. We experienced two cases of eroded polypoid hyperplasia(EPH) of the rectosigmoid colon which manifested as a huge gyriform mass simulating the gross features of gastrointestinal lymphomas or other malignant tumors. The EPH consisted of confluent polypoid mucosal folds with rolled-up submucosa to form stalk, The polypoid lesion represented hyperplastic epithelium, erosion of the mucosal surface and congestive vascular ectasia of lamina propria and submucosa. To explain the whole morphologic features, the initial phenomenon should be the mucosal prolapse. Vascular stretching with ischemic erosion of the mucosal surface and compensatory epithelial hyperplasia ensue as the result. The ominous endoscopic and gross features of EPH should be kept in mind to avoid erroneous radical surgery.

This study was conducted to determine the impacts of perceived stress and self-compassion on the quality of life of nursing students. Methods: Data were collected from 180 nursing students between 11 October and 26 October 2018 from a college in A city. A total of 157 questionnaires were analyzed using descriptive statistics, t-tests, a one-way ANOVA, Pearson correlation, and stepwise multiple regression. Results: The findings show that perceived stress had a significant negative correlation with quality of life (r=-.73, p<.001). However, self-compassion showed a significant positive correlation with quality of life (r=.66, p<.001). The factors influencing quality of life included perceived stress, self-compassion, state of health, and satisfaction with school life, with perceived stress being the most influential factor (β=-.42), followed by self-compassion (β=.30), which together had an explanatory power of 64.0%. Moreover, there was a mediating effect of self-compassion in the relationship between perceived stress and quality of life. Conclusion: The results of this study indicate that nursing college students should search for ways to reduce their perceived stress as well as increase self-compassion with meditation programs in order to improve their quality of life.

PURPOSE: To describe soft-tissue radiographic and high-resolution CT findings of radiation-induced lung injury of rabbit over time and to correlate them with pathologic findings. MATERIALS AND METHODS: 15 rabbits were irradiated in the right lung with one fraction of 2000 cGy. After 4, 6, 12, 20, 24 weeks, 3 rabbits in each group were sacrificed and soft-tissue radiographs and high-resolution CT of their lung tissue were obtained. Radiological findings were correlated with pathologic findings. RESULTS: On soft- tissue radiogram, radiation pneumonitis shown as consolidation with air-bronchogram occurred in 3 cases after 6 weeks, and in 1 case after 12 weeks of irradiation. In addition, pneumonic consolidation with adjacent pleural contraction was seen in 2 cases after 12 weeks of irradiation. Fibrotic changes indicated by decreased volume occurred after 20 weeks and combined bronchiectatic change and bronchial wall thickening appeared after 20 weeks(N=1), and 24 weeks(N=3). HRCT findings of radiation pneumonitis were homogeneous, increased attenuation after 4 weeks(N=3), 6 and 12 weeks (each N=I), patchy consolidation after 6 and 12 weeks(each N=2), discrete consolidation after 12, 20 and 24 weeks(each N=I) and solid consolidation after 20 and 24 weeks(each N=2). Pathologically radiation pneumonitis and pulmonary congestion were seen after 4 and 6 weeks. After 6 weeks, collagen and reticulin fibers were detected along alveolar wall. Mixed radiation pneumonitis and fibrosis were detected after 12 weeks. 20 weeks after irradiation, fibrosis was well defined in interstitium and in 24 weeks, decreased number of alveoli and thickening of bronchial wall were defined. CONCLUSION: Radiation pneumonitis was provoked 4 weeks after irradiation on rabbit lung and progressed into radiation fibrosis 20 weeks after irradiation on soft-tissue radiographs and high-resolution CT. High-resolution CT is more precise in detecting early radiation pneumonitis and detailed pathologic findings.

PURPOSE: Surgical sponges retained after laparotomy can cause serious problem if they were not be identified in early state. In these circumstances, abdominal CT yields the accurate diagnostic images. The purpose of this report is to present highly indicative findings permitting correct preoperative diagnosis of the gossypiboma. we experienced three cases in which CT showed the images sufficiently characteristic to suggest the correct preoperative diagnosis. MATERIALS AND METHODS: We evaluated retrospectively the radiological images of gossypiboma confirmed by operation. Three patients were admitted due to palpable masses. Two female patients had mdical histories of cesarean sections and a male patient had been operated due to malignant fibrous histiocytoma, previously. RESULTS: Abdominal CT scan of one case revealed huge ovoid hypodense mass with enhanced peripheral rim. Calcific spots and whirl-like stripes were noted within the lesion. Towel was found in pathologic specimen. CT images of two patients showed well-encapsulated, mixed fluid and soft tissue density mass with several gas bubbles. Surgical sponges were found within abscesses. CONCLUSION: The authors conclude that these characteristic CT findings and careful histories of surgery are very useful for correct pre-operative diagnosis and permit the guideline for the optimal plan of the surgical treatment.

Chronic eosinophilic pneumonia is a rare diasease characterized by chronic infiltration of the lung with ~eosinophils, usually associated with peripheral eosinophilia. In 65% of cases, the chest rad Ogroaph shows typiical nonsegmental air-space consolidation confined to the outer third of the lung and in 25)/0 of case "photographic negative of pulmonary edema". Typical lung manifestations with 'peripheral eosinophiliSa' tahrcharacteristic of chronic eosinophilic pneumonia. In the remaining cases, radiographic findings are nonspecific and require lung biopsy for confirmation. We repot a case of chronic eosinophilic pneumonia in which chest radiograph and CT scans revealed bilateral patchy or diffuse opacity with nodules scattered throughout the lungs.

PURPOSE: The purpose of this study was to provide a basis for non-humidified low flow oxygen by nasal cannula and to provide a guide for consistent care in nursing practice. METHODS: A methodological study on the development of guidelines with experts' opinions on collected items, framing PICO questions, evaluating and synthesizing texts which were searched with the key words (low flow oxygen, nasal cannula, humidification of oxygen, guideline) from web search engines. RESULTS: Of the 45 researched texts on the web, 9 texts relevant to the theme were synthesized and evaluated. All patients with humidified or non-humidified oxygen therapy reported that they had no discomfort. CONCLUSION: The results indicate that there are no tangible grounds for patients' perceived differences between the humidified and non-humidified oxygen under 4L/min supplied by nasal cannula. with oxygen. Therefore, non-humidification oxygen therapy is strongly advised when suppling under 4L/min oxygen by nasal cannula (recommended grade A).

PURPOSE: In the treatrnent of respiratory distress syndrome, Infants are often exposed to hyperoxia. It can generate oxygen free radical, damage to lung and bronchi, and inactivate pulmonary surfactant(PS). Antioxidant therapy in animal and human models has been tried to overcome this detrimental effects. We hypothesized that the addition of oxygen free radical such as hydrogen peroxide(H) could compromise surface active properties(SAP) of PS and that further addition of antioxidant such as catalaseR(CAT, Sigma chemical, St. Louis) could recover SAP. METHODS: We prepared combinations of mixtures with SurfactenR(S-TA, Tokyo Tanabe, Japan), H202 and CAT. 1)0.625mgPL(phospholipids)/ml or 1.25mgPL/ml S - TA and H202 were mixed to the final concentrations of 0.1 and 1mM H respectively, and incubated at 37C for one hour. 2) 0.625mgPL/rnl S - TA, H202 and CAT 10U were mixed to the final concentrations of lmM H202, and incubated at 37 degree C for one hour. We used Pulsating Bubble Surfactometer (Electronetics, NY) measure in vitro minimum and maximum surface tensions(ST) and area-surface tension relationship. RESULTS: 1) For 0.625mgPL/ml S-TA and 1mM H mixture minimum. ST after 5 min of pulsation increased significantly(P=0.007) and the area-surface tension curve was deformed. But they were comparable to control levels for 1.25mgPL/ml S-TA. 2) When CAT was added to 0.625mgPL/ml S-TA and 1mM H mixture, the resultant minimum ST after 5 min of pulsation dropped to the control levels with recovery of hysteresis curve(P=0.0001). CONCLUSION: PS could be inactivated by addition of high concentrations of H but SAP can be recovered either by increasing PS concentration or by further addition of antioxidant CAT. Therefore, we suggest that in case of suspected surfactant inactivation an increase in surfactant concentration or administration of antioxidant must be considered.
