It is not clear whether glomerular hypertrophy is related to the pathogenesis of focal segmental glomerulosclerosis (FSGS). We analyzed renal biopsies from 20 adults with FSGS by morphometry, and the data were compared with those from age- and sex-matched patients with minimal lesion. Mean glomerular volume in the FSGS group was significantly larger than that in the minimal lesion group[(3.4 + 1.1 vs 2.5 0.5)x10(6) micrometer3, P<0.01]. The percentage of glomeruli with global and segmental sclerosis in FSGS group was significantly correlated with the mean glomerular volume (r=+0.66, P<0.001). Relative interstitial volume of renal cortex in the FSGS group was correlated with the serum creatinine concentration(r=+0.5, P<0.05). These results suggest that glomerular hypertrophy observed in our patients with FSGS was related to nephron loss caused by glomerulosclerosis. The interstitial fibrosis may lead to obliteration of postglomerular interstitial capillary network with secondary elevation of glomerular capillary pressure resulting in progressive loss of renal function.

Trichilemmal horn(trichilemmal keratosis) is a rare keratinizing tumor that resembles a cutaneous horn. Histologically, it is characterized by an abrupt maturation of keratinocytes into lamellar keratin without the formation of a granular layer. We describe a case of a trichilemmal horn on the right cheek of a 78-year-old woman.

PURPOSE: Developing a curriculum(DACUM) is a method of analyzing job focused competency, which is obtained from the data of an expert belonging to a certain career. In this study the DACUM method was used to analyze the jobs of operating room nurses. METHOD: Through the DACUM workshop which was arranged by two DACUM facillitators, a definition of the role of operating room nurses was developed and then duties and tasks of operating room nurses' were identified. For the workshop, a DACUM committee with 10 operating room nurses was organized. Finally, the duties and tasks which were identified were validated by 422 nurses for importance, difficulty, and frequency. RESULTS: Thirteen duties and 105 tasks were identified on the DACUM chart, where importance, difficulty, and frequency of tasks were represented by alphabet letters A, B, and C as higher degree of importance. The determinant coefficient(DC) showed that the most important duty was assisting with operations(DC=6.61), and the least, managing operating materials(DC=4.22). For tasks, the most important ones were assisting in orthostatic surgery(DC=7.60), and assisting in thoracic surgery(DC=7.38), and the least important making gauze ball(DC=2.39), and saving of operation site((DC=3.27). CONCLUSION: The results suggest a need to develop an education program using the DACUM chart as a basis for the development and as a clinical career ladder and for curriculum of operating room nursing.

PURPOSE: This study was to verify the effects of a fluid therapy education program for aged stroke patients for preventing dehydration, pyuria and bacteriuria. METHODS: The study employed a non-equivalent control group pretest-posttest design in quasi experimental basis. Subjects were 38 stroke patients (20 in the experimental group and 18 in the control group) older than 65, hospitalized in a senior care center in S city, Korea. RESULTS: The amount of daily average fluid intake, normal ratio of blood urea nitrogen-creatinine ratio, serum Na+ and urine white blood cells were increased significantly in the experimental group. Normal ratio of bacteriuria increased in the experimental group, but not significantly. CONCLUSION: The education program is considered to be an effective nursing intervention tool for preventing dehydration and urinary tract infections which related to the secondary wellness of aged stroke patients. However, longer term study is necessary for better quality of nursing and developing more specific education programs for aged stroke patients usually hospitalized for a long period of time.

This reabstracting study was initiated to estimate accuracy and reliability of quality control for the Daegu Cancer Registry data in 1997-1998. The study population was 7,837 incident cases registered as malignant primary tumor in the Daegu Cancer Registry and two samples were selected for agreement study of the tumor and demographic information and for usual residence survey, separately. The 10 items reabstracted from medical records of 696 cases were compared to original data and classified as major and minor disagreement by the Centralized Cancer Patient Data System. The usual residence of 143 cases of one district was traced back actually through the computerized personal identification system of the government. The highest rate of major disagreements, 12%, was for morphology, followed by 12.0% for date of diagnosis and 5.6% for site. Demographic items had good reproducibility (exact agreement rates > 95%). Usual residence of 13 cases (9.1%) was out of Daegu. These results suggest that periodic assessment of the validity is necessary for quality control of the Daegu cancer registration data by the standardization of the cancer registration method including data collection method.

STATEMENT OF PROBLEM: A number of studies about the nano-treated surfaces of implants have been conducting along with micro-treated surfaces of implants. PURPOSE: The purpose of this study was to get information for the clinical use of nano-treated surfaces compared with micro-treated surfaces by measuring removal torque and analyzing histological characteristics after the placement of various surface-treated implants on femurs of dogs. MATERIAL AND METHODS: Machined surface implants were used as a control group. 4 nano-treated surface implants and 3 micro-treated surface implants [resorbable blast media surface (RBM), sandblast and acid-etched surface (SAE), anodized RBM surface] were used as experimental groups. Removal torque values of implants were measured respectively and the histological analyses were conducted on both 4weeks and 8weeks after implant surgery. The surfaces of removed implants after measuring removal torque values were observed by scanning electron microscopy (SEM) at 8 weeks. RESULTS: 1. Removal torque values of the nano-treated groups were lower than those of micro-treated groups. 2. Removal torque values were similar in the anodized RBM surface groups. 3. On the histological views, there was much of bone formation at 8 weeks, but there was no difference between 4 and 8 weeks, and between the types of implant surfaces as well. CONCLUSION: It is suggested that implant topography is more effective in removal torque test than surface chemistry. To get better clinical result, further studies should be fulfilled on the combined effect of surface topography and chemistry for the implant surface treatments.
