OBJECTIVES: The purpose of study was to define the clinical and epidemiological factors of HNP and to provide the meaningful sources for establishing a prognosis and a rationale for clinical management of occupational low back problem. METHODS: This study was performed at eight branch hospitals of Catholic University of Korea and several governmental hospitals f or occupational disorders around the Kyunggi province of Korea since Jan. 1985. We analyzed the several factors about lumbar HNP through comparative study of the hospital admission series of each 200 patients in both occupation- and nonoccupation related, subjected to epidemiologic and clinical investigation, respectively. RESULTS: 1. Mean age of occupational HNP was younger(30.9+/-8.8) than non-occupational HNP(35.2+/-10.5) (p<0.05). 2. The duration of clinical symptom before admission was longer in non-occupational HNP(19.9+/-22.8 Mo.) than in occupational HNP(6.9+/-12.4 Mo.) (p<0.05). 3. The symptomatic attack before admission was more frequent in non-occupational HNP(3.7+1.9) than in occupational HNP(2.5+/-0.9) (p<0.05). 4. There were no significant differences in physical findings between two groups, except for low rate(63%) of straight leg raising test(SLR) limitation in occupational HNP compared to non-occupational HNP(83%) (p<0.05). 5. Even though The main reason for operative intervention was a failure of conservative treatment in both groups(p<0.05), extruded subligamentous type was predominant(50%) in occupational HNP(p<0.05), whereas extruded transligamentous type occupied major portion(67.8%) in non-occupational HNP(p<0.05). CONCLUSION: The clinical results were poor in occupational HNP in both conservative and operative management groups, compared to non-occupational HNP(p<0.05) and mean durations admission and re-admission rate was higher in occupational HNP, compared to non-occupational HNP (p<0.05).

BACKGROUND: There has been no general agreement on classifying basal cell carcinoma (BCC), and little is known about the squamous cell differentiations of each subtype of BCC. BCC is a locally-invasive tumor, but its aggressive forms tend to recur and metastasize. OBJECTIVE: We have compared the histolopathological subtypes of BCC by squamous differentiation, with special emphasis on basosquamous carcinoma and the difference between the non- aggressive and aggressive forms of BCC. MATERIALS AND METHOD: A total of 87 BCC specimens were collected from the 7 branch hospitals of The Catholic University of Korea from July 1997 to June 2003. RESULTS: 1. The 87 samples were divided into 6 subtypes: 18 nodular, 19 nodular infiltrative, 12 micronodular, 14 infiltrative, 11 morpheaform, 13 basosquamous. Overall, 18 samples were classified as non- aggressive and the remaining 69 as aggressive. 2.In nodular-infiltrative BCC and basosquamous carcinoma, squamous cell differentiation was significantly more prominent than in the nodular BCC. CONCLUSION: Squamous cell differentiation should be considered as one of the aggressive markers, especially in nodule-forming BCC.

We developed the Tele-PACS of radiology, which uses the communication network as asymmetric satellite data communication system. The asymmetric satellite data communication system uses receive-only satellite links for data delivery and PSTN(Public Switched Telephone Network) modem or N-ISDN(Narrow-band Integrate Services Digital Network) for communication. The satellite communication linking we implemented showed the very high-speed performance compared to the terrestrial linking such as 28.8 kbps modem linking or 56Kbps linking. The satellite linking was 5-10 times faster than the terrestrial linking on the average. We developed the down-link system of satellite and the medical collaborative tools and the Web-based Image-viewer. We concluded that 1) Satellite networking is currently the cheapest and fastest solution for internet access. 2) Web-based Image-Viewer enables small size hospitals in rural area to connect to the central PACS easily and to retrieve the image data reliably. 3) The suggested teleradiology system using satellite networking could be adequate to the fast telemedicine and telecare for rural hospitals especially located in geographically isolated areas such as islands.

BACKGROUND: There has been no general agreement in classifying basal cell carcinoma (BCC), and little is known about the immunohistochemical profiles in each subtypes of BCC. BCC is a locally-invasive tumor, but its aggressive forms tend to recur and metastasize. OBJECTIVE: In this study, we have compared the histolopathological subtypes of BCC by immunohistochemical study. We also focused on identifying representative markers of growth in the aggressive forms of BCC by assessing VEGF, p53 and alpha-SMA expression. METHODS: A total of 87 BCC specimens were collected at the 7 branch hospitals of The Catholic University of Korea from July 1997 to June 2003. For multiple immunohistochemical staining, a tissue microarray technique was used. The 87 samples were divided into 6 subtypes: 18 nodular, 19 nodular infiltrative, 12 micronodular, 14 infiltrative, 11 morphea and 13 basosquamous. Overall, 18 samples were classified as non-aggressive and the remaining 69 as aggressive. RESULTS: The following results were obtained after immunohistochemical staining with antibodies alpha-SMA, VEGF and p53. A significant increase of alpha-SMA expression was observed in aggressive forms of BCC, whereas the expression of p53, VEGF, the number of mast cells remained the same. The representative markers of tumor growth such as alpha-SMA were most highly expressed in the basosquamous type, and least expressed in the micronodular type compared to the nodular type. CONCLUSION: alpha-SMA was considered as an appropriate immunohistochemical marker in BCC to represent aggressiveness.

The authors developed a computerized documentation system to record and store all the data pertaining to an endoscopic examination of the upper digestive tract. The system was programmed using the database management system Clipper Version 5.01. It is easy and convenient to use due to advanced deaign of input screen using menu bars and pull down menu and windows. The system was designed to permit the easy storage and retrieval of data by personnel who lack computer skills and who may only have limited typing ability. Today this system has been in daily use for 1 year at the endoscopic units of 8 different branch hospitals of Catholic university,medical college. Overall the experience in these centers has been positive, with excelient or good participation. Characteristics of this system are a menu-driven system, data input by predefined list, instantaneous report generation, on line access to previous examination, late entry of yathologic regerts. and record retrieval, listing according to different criteria. For the description of endoscopic findings and diagnosis, structured input is maintained. All of the findings are chosen from predefined list using pop-up screen and also free text typing is allowed. Therefore time effort was not increased compared to conventional documentation. Structured input and the resulting categorical data affer several advantages.

BACKGROUND: Dermatophytosis is sometimes difficult to diagnose deinitively if it has atypical clinical characteristics and mycological tests are negative. Histopathologic findings may be different depending upon the location and causative dermatophytes. OBJECTIVE: The purpose of the present study was to evaluate histopathologic characteristics nf dermatophytosis depending upon the areas of involvement. METHODS: We evaluated the clinical and histopathologic features of 32 cases of dermatophytosis which were diagnosed by skin biopsies at the Dermatology Department of branch hospitals of Catholic University Medical College from March 1985 to August, 1994. Histopathologic features were observed in three dilferent groups divided by location, area of terminal hair, areas of vellus hair and hairless areas. RESULTS: Epidermal changes including hyperkeratosis, parakeratos, acanthosis, spongiosis and neutrophilic exocytosis were frecuently observed in the three groups of Iermatophytosis. In 7 cases of tinea capitis and linea barbae, follicular and inflamma or changes of the deep dermis were important. Hyphae and spores were observed in 71%(5 cases) and 57%(4 cases) respectively, in the follicles. In 19 cases of tinea faciale, tiriea corporis and tinea cruris, change epidermis and superficial dermis as well as findings of follicular infundibulum were important. Herphae were observed in 84%(16 cases) and 53%(10 cases) in the stratum corneum and vellus hir follicle respectively, and in 3 cases the hyphae were observed only in the vellus hair follicle. Sandwich sign, known to be important clue of dermaliophytosis, was observed in only 5%(1 cacse, In 6 cases of tinea manus and linea pedis, hyphae and spores were rebserved in 100% (6 cases) and 33%(2 cases) respectively, in the stratum corneum. CONCLUSION: We consider tha histopathologic observations may of great help to diagnose some difficult cases of dermatophytosis and the presence of hyphae n .he vellus hair follicle may be a more frequent and important finding than the sandwich sign the dermatophytosis of the vellus hairy regions.

PURPOSE: This study was done to identify the intensive care unit nurses' knowledge of and compliance with the standard precautions (universal precaution) as stated in infection control guidelines. METHOD: From September 14 to September 28, 2006, data were collected via a questionnaire survey from 189 Intensive Care Unit nurses working at three university branch hospitals and one general hospital in Gyeonggi province. RESULTS: The mean knowledge score was 18.8/20.0 (93.9%). The mean compliance score was 3.4/4.0 (85.8%). Two factors influencing compliance were perception of the standard precautions and experience of needle stick injuries over the past year (p<.05). Two factors influencing knowledge were support of co-workers in the use of protective devices and the availability of hand-washing device or waterless alcohol gel (p<.05). CONCLUSION: In order to improve knowledge and compliance with standard precautions, all factors of importance for knowledge and compliance must be taken into consideration in the clinical work place and in education.
