Methicillin-resistant Staphylococcus aureus colony variants (SCVs) are frequently auxotrophic for hemin, menadione, thiamine, and CO2 involved in biosynthesis of the electron transport chain element. This phenotype grows slowly, and forms very small, nonhemolytic colonies in routine culture, so it may be led to the misidentification of this organism. We isolated an organism with catalase-positive, gram-positive cocci in cluster from the urine of a 55-years-old woman with persistent and relapsing bladder stone, who had undergone the antibiotic treatment with cefotaxime, ceftizoxime, amikacin, and/or micronomicin, intermittently for three years. The possibility of SCVs should have been ruled out because this organism didn't grow on Mueller-Hinton agar (MHA) for the susceptibility test. It formed small colonies on blood agar plate overnight, and grew only on MHA with supplement of hemin, or with 5% CO2. This organism was coagulase-positive, DNase-positive, manitol-salt positive, and identified as S. aureus with VITEK GPI card. The susceptibility test could be performed after adding hemin(1mg/mL) into bacterial suspension and showed susceptibility against vancomycin, teicoplanin, and rifampin. Because these phenotypes can be misidentifide as other non-pathogenic organisms due to their atypical characteristics, we should consider SCVs in case of small, nonhemolytic colonies with catalase-positive, gram-positive cocci in cluster, showing no growth on MHA. In addition, infections caused by SCVs are recently recognized in relation to persistent and relapsing infection, so they could be isolated from the patients with long-term antibiotic therapy.

Localized fibrous tumor is an uncommon submesothelial origin tumor found in pleura most commonly. Sixty five-year-old man with right lower quadrant pain was admitted. He was treated with resection of tumor and was diagnosed as localized fibrous tumor of pelvic cavity. He is now being followed up without any evidence of recurrence for 34 months. This case is presented with reviewing references.

The cell surface glycoprotein CD44 is a kind of adhesion molecule, which binds hyaluronic acid, type I collagen and fibronectin. Although there have been numerous reports on the expression and the function of CD44 in lymphocytes and macrophages, very little is known about its distribution and definite role in epithelial tissue, especially in oral epithelial one. The present study was performed to investigate the distribution and expression of the CD44 in human gingiva and squamous cell carcinoma(SCC) arising in human gingiva. And the authors compared CD44 expression with histopathologic grade of SCC. The results were as follows: 1. The CD44 was strongly expressed in granular, spinous and basal layers of normal marginal and attached gingiva, in spinous and basal layers of normal sulcular gingiva, and in all epithelial layers of normal junctional gingiva. 2. In SCC of gingiva, the CD44 was expressed in all but one case. In most of the cases the CD44 was expressed at cell membrane and the degree of expression was relatively strong. 3. In low-grade SCC of gingiva, the CD44 was strongly expressed, especially at the basal and spinous layers of abundantly keratinized cancer nests. In high-grade SCC of gingiva, the CD44 expression tended to be weak but was strong at cells showing individual keratinization. This study suggest that the CD44 expression of normal and cancerous gingival epithelium is associated with the degree of proliferation and differentiation of epithelial cells.

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.

Ureteroscopic management of ureteral calculi is an established successful technique with low complication. We performed 140 ureteroscopies for stone removal from January 1990 to April 1995. The stone were removed successfully in 131 cases (94%), and complication occurred in 37 cases (27%). In 9 cases, complete removal of stone was failed due to upward migration of stone (3 cases), not mobilization of stone (3 cases), inability to introduce ureteroscope into the intramural ureter (2 cases), inadequate illumination due to bleeding (1 case). Complications of ureteroscopic removal of stone were ureteral perforation (8 cases), tearing of ureteral mucosa (5 cases), gross hematuria (19 cases), infection (3 cases) and fever (2 cases). All complications were treated successfully with conservative treatment. We conclude that ureteroscopic removal of stone is still primary useful treatment of middle and lower ureteral stones and can be done safely if certain guide lines such as proper selection of patient, adequate use of lithotriptor, careful dilatation of ureteral orifice are kept strictly.

PURPOSE: The purpose of the study was to identify characteristics of nursing and caring concepts measured by nursing competencies or caring behaviors tools for general nurses working in acute care hospitals. METHODS: Five major nursing literature databases were used to identify the relevant tools. The study included 19 nursing competencies tools with a total of 843 measurement items and 12 caring behaviors tools with 334 items. According to the International Council of Nurses (ICN)'s Competencies Framework and 8Cs suggested by Roach (1987) and Pusari (1998), the measurement items were classified by two researchers independently first and in agreement finally. RESULTS: Competency of ‘key principles of care’ including sub-areas of the ICN Framework was most commonly found: on average 49.3% of nursing competencies items and 91.9% of caring behaviors items. 97.0% of the caring behaviors items were classified into one of six Cs: competence (27.5%), confidence (21.3%), compassion (17.1%), commitment (16.5%), communication (9.9%), or conscience (4.8%). CONCLUSION: Nursing competencies tools were more likely to measure ‘what to do’ focusing on tasks, while caring behaviors tools were to measure ‘how to do’ focusing on nurses' attitudes or values. Nursing practices should be evaluated with both nursing competencies and caring behaviors tools, considering that nursing and caring were differently conceptualized in the quantitative tools.
