PURPOSE: To implement evidence-based nursing, it is important to know where and how to find the best available evidence. This study was conducted to identify the results of a search from Ovid MEDLINE and to compare the results from Ovid MEDLINE with those from PubMed MEDLINE. METHODS: Four different approaches via Ovid MEDLINE were used to search for guidelines on preventing catheter-associated urinary tract infections. Outcomes of this study were the number of records and relevant literature, and the sensitivity and precision of the search methods via Ovid MEDLINE. RESULTS: The number of retrieved items ranged 23 to 6,005 and that of relevant studies, 5 to 8 of 8. Simple searches resulted in the highest sensitivity of 100.0%. When using MeSH terms and limits feature, the precision was highest (21.7%) among four approaches for literature searches. Simple searches in Ovid had higher sensitivity and lower precision than those in PubMed. CONCLUSION: Simple searches in Ovid may be inefficient for busy clinicians compared to PubMed. However, to ensure a comprehensive and systematic literature search, using Ovid MEDLINE in addition to PubMed is recommended.

PURPOSE: We measured pulmonary epithelial permeability by Tc-DTPA radioaerosol clearance in patients with diabetes and correlated with the presence of microangiopathy to understand the pathophysiology of pulmonary microangiopathy and evaluate Tc-DTPA radioaerosol clearance as a diagnostic test to assess pulmonary microangiopathy. MATERIALS AND METHODS: We performed ' Tc-DTPA radioaerosol scan in 10 normal subjects, 10 asym-ptomatic smokers, 20 diabetic patients without history of smoking (10 with microangiopathy, 10 without microangiopathy). Tc-DTPA clearance half-time (T1/2) was calculated, then compared with the result of chest radiography and pulmonary function test. RESULTS: Chest radiography and pulmonary function test were normal in all subjects. There were no significant difference of clinical or laboratory characteristics between these groups except age. The diabetic patients with micraangiopathy were significantly older (p<0.05). The T1/2of normal subjects and asyrnptomatic smokers were significantly different (65.2+23.7min vs 39.6+9.8min, p<0.05). For diabetic patients with microangiopathy, the T, was 90 5+46.5min and significantly delayed when compared with those of normals and asymptomatic smokers (p<0.05). However, the T1/2of diabetic patients without microangiopathy, 70.0+12.7 min, was not significantly different from those of normals or asyrnptomatic smokers (p>0.05). No significant correlation was found between the T1/2and spirometric parameters including DLcc>, FVC, FEV>, FEV(/FVC (%) and FEF)5-75g in all subjects, and between the T1/2 and duration of diabetes in diabetic patients. CONCLUSION: Eventhough the influence of age cant be excluded, delayed Tc-DTPA clearance half-time (T1/2)in diabetic patients with microangiopathy indicates decreased pulmonary cspillary permeability as one of the pathophysiologic results of pulmonary microangiopaththy. Further studies are needed in larger number of age matched control and diabetic patients to evaluate the diagnostic efficacy.

PURPOSE: This study was conducted to examine the effects of simulation-based education regarding care in a cardio-pulmonary emergency care as related to knowledge, clinical performance ability, and problem solving process in new nurses. METHODS: An equivalent control group pre-post test experimental design was used. Fifty new nurses were recruited, 26 nurses for the experimental group and 24 nurses for the control group. The simulation-based cardio-pulmonary emergency care education included lecture, skill training, team-based practice, and debriefing, and it was implemented with the experimental group for a week in May, 2009. Data were analyzed using frequency, ratio, chi-square, Fisher's exact probability and t-test with the SPSS program. RESULTS: The experimental group who had the simulation-based education showed significantly higher know-ledge (t=5.76, p<.001) and clinical performance ability (t=5.86, p<.001) for cardio-pulmonary emergency care compared with the control group who had traditional education but problem solving process was not included (t=1.11, p=.138). CONCLUSION: The results indicate that a simulation-based education is an effective teaching method to improve knowledge and clinical performance ability in new nurses learning cardio-pulmonary emergency care. Further study is needed to identify the effect of a simulation-based team discussion on cognitive outcome of clinical nurses such as problem solving skills.

PURPOSE: The purposes of this study were to develope and evaluate a constipation intervention program for inpatients. METHOD: To develope this program, Six phases were processed including the organization of team, the analysis of medical chart, the development of tentative constipation intervention program, the test of content validity, the test of clinical validity and the determination of final constipation intervention program. To evaluate the clinical validity of this program, 10 subjects who were in the C University Hospital were selected from March, 2001 to October, 2001. RESULT: The clinical validity was supplied by the pilot test, showing the potential effect of the program. Based on the validity results the final algorithm and the form of nursing record for this program which consist of the 3-step assessments and the intervention protocol were presented in this study. CONCLUSION: The advantage of this program is being able to assess and manage constipation simultaneously and is especially effective to patients who are at risk for developing constipation during their admission. Further study needs are also necessary to evaluate the effect of this program on the self-symptom of constipation.

PURPOSE: Effective literature searching is essential to support evidence-based nursing. The aim of this study was to present our recent systematic search experience to identify guidelines in PubMed for prevention of catheter-associated urinary tract infections. METHODS: Five approaches to the literature search via PubMed were employed. The searches were restricted to items published from 1980 to 2010, for patients admitted to hospital, and in the English language. The search results were compared using the number of records and relevant items, and the sensitivity and precision of each search strategy. RESULTS: The individual approaches retrieved 19-141 of records and 3-6 of relevant items. Sensitivity ranged from 37.5% to 75.0% with the highest values for simple searches and a search combining MeSH terms and free textwords with a methodological search filter. Precision varied from 4.3% to 21.7% and the highest precision was found for MeSH terms with limits feature. CONCLUSION: The simple search in PubMed is an appropriate way for nurses in a busy clinical practice to search the literature for evidence. However, several approaches using MeSH terms, free textwords, limits feature or methodological search filters are also required to have more efficient and better informed search results.

PURPOSE: The purpose of this study was to test the validity of a modified clinical performance examination (CPX) for preclinical students in nursing. METHOD: 70 nursing students in their second semester of the junior year at C University participated in CPX. Scenarios and checklists were developed by our research team from September to October 2005. Six stations were organized. Evaluation included physical examination of a patient with lung cancer, education on usage of a metered dosage inhaler, and lobectomy postoperative care. Students were randomly assigned to a station. RESULT: There was a difference in the CPX scores according to stations. The agreement of scoring between trained faculty members and SPs was more than moderate (r=.647). The correlation between the CPX score and the average grade in the previous semester and between the CPX score and the average grade of a paper and pen test of the pulmonary system of adults was low (r=.276; r=.048). CONCLUSION: Traditional CPX is generally recommended, however, modified CPX is appropriate for preclinical students in the current Korean Nursing school setting if there are additional scoring systems to balance the testing level at each station.

Nasal lymphoma is an uncommon neoplasm in the sinonasal tract. The NK/T-cell type of lymphoma is more commonly found in Asian populations. However, B-cell lymphoma is more common in the western countries whereas it is rare in Asia. Recently, we experienced two cases of sinonasal B-cell lymphoma, which are rare cases in Korea, one in an advanced stage and one in an early stage. Both patients had no specific nasal symptoms or systemic B symptoms (fever, night sweat, weight loss). As our cases demonstrate, diagnosis of B cell lymphoma is often delayed in many cases because B-cell lymphoma does not show any specific symptoms. Thus, careful physical examination and biopsy under suspicion of malignancy are important for early diagnosis of nasal lymphoma.

BACKGROUND: Since the nonsurgical treatment of mitral stenosis using a single balloon has been introduced by Inoue et al. in 1984. percutaneous mitral valvuloplasty has became an accepted therapeutic modality for selected patients with mitral stenosis. Zeibag et al. demonstrated the double balloon technique showed a better outcome than the single balloon in obtainning the optimal mitral valve area. On the other hand, there are several reports that single balloon technique was comparable with the double balloon technique. Therefore, there are still controversies in efficacy, benefit and complications between balloon techniques. METHOD: To compare the efficacy and complications of percutaneous mitral valvuloplasty with the double balloon or the Inoue balloon technique, 40 patients were studied consecutively by random method in selecting the balloon technique. RESULTS: In all cases, percutaneous mitral valvulopasty was performed successfully. Optimal outcome defined as mitral valve area larger than 1.5cm2 was obtained in 12 cases out of 16(75%) in double balloon group and 15 out of 24(63%) in Inoue balloon group(p=NS). Mitral valve area was significantly increased after valvulopasty in both technique but there was no different between both groups(Mean+/-SD ; 0.9+/-0.3 to 1.7+/-0.2 vs 0.9+/-0.2 to 1.9+/-0.2cm2). There were also hemodynamic improvement significantly in mean mitral gradient(MG). pulmonary artery pressure (PAP) and left atrial pressure(LAP) after PMV but there were no difference between groups (18+/-8 to 7+/-2 vs 21+/-13 to 9+/-4 mmHg for MG. 29+/-12 to 22+/-9 vs 28+/-9 to 18+/-5mmHg for PAP and 22+/-8 to 11+/-5 vs 21+/-6 to 11+/-4 for LAP respectively). Mitral requrgitation greater than grade 2 occurred in 2 cases of the double balloon group and one case of the Inoue balloon group(p=NS). New development of atrial shunt was found in 3 cases in both groups. CONCLUSIONS: The double and Inoue balloon techniques were quite comparable in immediate outcome and complications.

PURPOSE: Matrix metalloproteinase-2 (MMP-2) and MMP-7 have been implicated in tumor growth and metastasis. This study aimed to investigate the expressions of MMP-2 and -7 in colorectal cancer and to evaluate their values as prognostic markers. METHODS: Immunohistochemical staining for MMP-2 and -7 was done in 144 resected colorectal cancer specimens. Clinicopathological data and survival results were compared with regard to the expression results. RESULTS: The expression rates of MMP-2 in tumor cells in the tumor center and the tumor border were 16.7% and 38.9%, respectively. That of MMP-2 in stromal cells was 27.8%. MMP-7 immunoreactivities of tumor cells in the tumor center and the tumor border were 6.9% and 23.6%. The expressions of MMP-2 and MMP-7 were correlated. MMP-2 expression in stromal cells was more increased in the distal part of the colorectum: 8.8% in right colon cancer, 29.5% in left colon cancer and 36.4% in rectal cancer. MMP-2 expression of tumor cells in the tumor border was correlated with T-stage. MMP-7 expression of tumor cells in the tumor border was increased in case of infiltrative cancer compared with fungating tumor. The expression patterns of MMP-2 and -7 were not correlated with other clinicopathological factors, including tumor markers, node metastasis, distant metastasis, lymphatic invasion, tumor differentiation, and recurrence. No significant associations between the overall and disease-free survival rates and the MMP-2 and -7 expression patterns were noted. CONCLUSION: The high expression rates of MMP-2 and -7 in tumor borders suggest that MMP-2 and -7 have some role in tumor invasion, but in this study, MMP-2 and -7 did not appear to be significant predictors of prognosis in colorectal cancer.
