Myxofibrosarcomas (MFSs), which consist of multiple nodules with a variable cellular population in a myxoid matrix, are primarily located in subcutaneous tissue. Pleomorphic hyalinizing angiectatic tumors (PHATs) are rare soft-tissue tumors characterized by a proliferation of highly pleomorphic spindle or polygonal cells and abundant ectatic blood vessels in cellular or myxoid stroma. We present here an unusual case of a high-grade MFS with a PHAT-like appearance. A 67-year-old man presented with an asymptomatic subcutaneous mass in the right forearm. The tumor had myxoid, hypo-, and hypercellular areas with highly pleomorphic spindle or polygonal tumor cells that showed frequent mitoses and nuclear pseudoinclusions. Foci of punctuate necrosis and inflammatory infiltration were present throughout the tumor, and abundant ectatic, thick-walled vessels containing blood clots were noted. The tumor cells were immunohistochemically positive for vimentin but negative for CD34, S-100 protein, smooth muscle actin, desmin, and bcl-2.

PURPOSE: The objective of this study was to investigate the influence of hospital nurses' self-leadership, communication skill, and self-esteem on the quality of nursing service. METHODS: The participants, 230 nurses working at a general hospital in Seoul, completed a cross-sectional descriptive questionnaire survey between January 17 and 28, 2014. The collected data were analyzed using the SPSS 19.0 program for descriptive statistics, t-test, one way & two way ANOVA, correlation, and multiple regression analysis. RESULTS: Nurses' self-esteem and communication skill had significant main effects on self-leadership and the quality of nursing service, but the interaction effect of the two independent variables was not significant. Variables that significantly influenced the quality of nursing service were self-leadership, communication skill, self-esteem, and career longevity. The explanatory power of these variables for the quality of nursing service was 54.4%. CONCLUSION: Findings indicate a need for education programs for nurses which are designed to promote communication skill and enhance self-esteem and self-leadership skills which will in turn enhance the quality of nursing service.

BACKGROUND: The diagnosis of tuberculosis has been based on the detection of tubercle bacilli by acid-fast stain of smear or cultures, and recently the serologic diagnosis of tuberculosis has been provided a means of sensitive and specific detection of Mycobacterium tuberculosis. We evaluated the utility of enzyme immunoassay using determiner Tuberculosis Glicolipids(TBGL) antibody kit(Kyowa Medex Co. Ltd, Japan) to detect anti-TBGL antibody for diagnosis of pulmonary tuberculosis. METHODS: Anti-TBGL antibody assay was performed to the form 44 patients with active pulmonary tuberculosis(17 patients with smear positive, 7 patients with only culture positive, 20 patients with clinically active tuberculosis) and 80 controls (30 healthy controls, 24 patients with non-tuberculous respiratory diseases, 26 patients with inactive tuberculosis). We compared the sensitivity and specificity of anti-TBGL antibody with culture and AFB stain. RESULTS: Anti-TBGL antibodies were detected in 16 of 17(94%) smear positive patients, 4 of 7 patients with only culture positive and 16 of 20(80%) smear negative patients who had been clinically diagnosed as active pulmonary tuberculosis. Nine(35%) out of 26 patients with inactive tuberculosis, one(4%) out of 24 patients with non-tuberculous respiratory diseases and no one of healthy control had a positive antibody response. Overall sensitivity, specificity of the anti-TBGL antibody assay were 82%, 88%, respectively and sensitivities and specificities of culture and AFB smear 64%, 97%, and 49%, 100%, respectively. Anti-TBGL antibody titers in patients with active tuberculosis were significantly higher than control grup(P<0.05). Conclusions : The anti-TBGL antibody assay was sensitive, rapid and convenient. This assay will be useful as a tool for the diagnosis of tuberculosis in combination with other conventional methods.

PURPOSE: To evaluate differential points of patterns of clustered microcalcification between malignant(n=17) and benign(n=46) lesions on mammogram MATERIALS AND METHODS: We retrospectively and prospectively evaluated mammograms of surgically confirmed 63 patients showing clustered microcalcifications. Area, density, number, size, shape of calcification were evaluated along with associated mass and parenchymal distortion. RESULTS: Malignant calcifications were more variable in size(14/17, 77% vs 25/46, 53%) and shape(l 1/17, 64. 8% vs 13/46, 28.2%) than benign counterparts. Pepper, fine granular, branching, comma, tadpole and wormiform calcification were observed in malignant lesion with statistical significance. The malignant calcifications showed more faint(12/17, 70.5% vs 23/46, 50%), irregular margin(17/17, 100% vs 19/46, 42%) and they were usually associated with parenchymal distortion(16/17, 94% vs 9/46, 20%) and ill-defined masses(10/17, 58.9% vs 12/46, 26.1%). CONCLUSION: Clustered microcalcifications with variable size and shape, faint or irregular margin, parenchymal distortion, ill-defined masses seen on mammography, suggest malignancy.

With simple abdomen, double contrast colon study, and ultrasongraphy, authors retrospectively analyzedradilogic findings of 46 cases which were proved periappendiceal abscess, due to perforation of appendix, byhistology or follow-up ultrasnongraphy from May in 1983 to July in 1985 at Yeung-Nam University Hospital. Theresuls obtained were as follows: 1. Of 46 cases, 24 cases were males and 22 cases females, with the results ofabove statistics, periappendiceal abscess was not influenced by sex. 2. Periappendiceal abscess was mostfrequently demonstrated in forties. 3. Comparison of ultrasonography and B.E. Pseudorenal pattern(Ultrasonography)- well defined defect (B.E.) Cystic pattern(Ultrasonography)- serrated defect (B.E.) 4. Missed 2 cases inultrasonography were detected in B.E., i.e. sensitivity of B.E. is higher than that of ultrasonography. 5.Differences of ultrasonography and B.E.

Adenosis tumor is a ra re tumor of the breast and primarily consists of adenosis. Authors report a case of surgically proved adenosis tumor in a 31-year-old woman. Mammogram showed a Iobulated, well-circumscribed mass with several surrounding radiolucent halos. In the center of the mass several linear radiolucent densities were seen with the appearance of a conglomerated well-circumscribed mass such as fibroadenoma. These linear radiolucent densities were consistent with the fat between the fibrous sclerosis in pathologic specimen. Ultrasonogram showed a well-circumscribed mass with homogeneous low echogenicity, partial posterior enhancement, and bilateral acoustic shadowings.

BACKGROUND: Urography(IVU) is considered the best first investigation in patient with suspected urinary calculi, but recently ultrasonography(USG), combined with a plain film of the abdomen, has been suggested as an alternative. METHODS: We undertaken study to see if this approch can be used in emergency patients and outpatients by radiologists with different amounts of ultrasound experence. Some 192 patients with suspected urinary colic presenting to Koo Hospital Emergency Department and Youngnam Universith Hospital outward Department(IM, URO, FM) over 12-month period were studied. They had a plain abdominal film(KUB) and USG examination of the kidney, ureter, bladder following hydration and subsequently underwent IVU. Of these, 22 patients passed a stone before their IVU. The data analysis was performed on the remaining 170 patients. Urography was used as the gold standard. RESULTS: Some 170 patients subsequently underwent IVU at a mean interval of 1.8 days after the ultrasound examination. In 91 of 170 patients the IVU was positive. In 97 of 170 patients the combination of JUB plus USG was positive, leaving three false negative KUB plus USG. Thus the sensitivity of KUB plus USG was 97%, specificity was 89%, positive predictive value was 91%, and negative predictive value was 96%. CONCLUSIONS: Our findings in this study suggest that in the hydrated patient the combination of KUB plus US is a very sensitive and relative specific screening test. Because of the high negative predictive value of KUB plus US, urography is not likely to be helpful when KUB plus US are negative. Urography is indicated only if KUB plus US findings are equivocal or if intervention is necessa.ry.

We performed immunohistochemical stain of p-glycoprotein using JSB-1 monoclonal antibody to study multidrug resistant(MDR) gene expression in 137 gastric tumor tissues obtained from 87gastric carcinoma patients. The incidence of p-glycoprotein expression was 60 of 87 cases(69%) and it was not correlated with age, sex, depth of tumor invasion, and lymph node metastasis, but was correlated with histologic type of gastric adenocarcinoma. The distribution of p-glycoprotein positive cells in the tumor tissue was diffuse in 34 cases(73.9%) and focal in 12 cases(26.1%), and the dominant staining patterns of p-glycoprotein in the tumor cells were cytoplasmic and golgi staining in 20 cases(43.5%) and 19 cases(41.3%), respectively, and 7 cases(15.2%) showed fine granules in the cytoplasm. The incidence of p-glyco-protein expression in the tumor tissue was higher in A and AB blood type patients who have A antigen than in 0 and B blood type patients. Cytoplasmic staining pattern was dominant in O and B blood types and golgi staining in A and AB blood type patients. Among 27 patients 'who received chemotherapy, partial remission was noted in 9 of 11 p-glyco-protein negative patients(81.8%) and no remission or progression of the tumor was seen in 9 of 16 p-glycoprotein positive patient(56.3%). The p-glycoprotein expression in gastric carcinoma had no direct correlation with known several prognostic factors of the gastric tumor except for histologic type, and it is supposed that p-glycoprotein detection in gastric tumor tissue by immunohisto-chemical stain is a good method for predicting the response of chemotherapy, especially in p-gly-coprotein negative cases.

PURPOSE: The purpose of this study was to compare knowledge level of those clinical nurses who received HPV vaccine and those who did not and their perception of the relatedness of HPV vaccine to causes of cervical cancer. METHODS: A total of 249 clinical nurses were surveyed from June to July, 2009. The questionnaire originally developed by Kim & Ahn (2007) examined HPV-related knowledge originally and the tool for perception of the causes of cervical cancer was originally developed by Kim (1993). The total number of subjects equaled to: vaccination group of 52 (20.9%) and non-vaccination group of 197 (79.1%). RESULTS: Vaccination group showed significantly higher score of both knowledge of HPV vaccination and the perception of the cause of cervical cancer in comparison to the nonvaccination group at (p<.05). Among 4 subscales of the perception of causes of cervical cancer, destiny and constitution subscale scores were significantly different between the two groups at (p<.05). CONCLUSION: Clinical nurses need to constantly update with current knowledge of HPV and be prepared with currently changing cancer prevention strategies, especially in cervical cancer.
