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.

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.

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.

A 52-year-old man was found dead in the driver's seat of his tank lorry. The tank lorry was used to transport industrial wastewater to a disposal plant; the material was transferred into a storage tank with the help of compressed air. The wastewater contained methylene chloride and 2-chloropyridine. No respiratory protective equipment was used while working under these conditions. The autopsy report showed extensive edema and congestion of the brain, lung, and intraperitoneal organs. The concentrations of methylene chloride in lung and brain were reported at 398 and 67 mg/kg, respectively.

PURPOSE: This study aims to identify the general characteristics, subjects, and methods of research on the health of North Korean refugees through a systematic literature review. METHODS: A total of 140 studies on health were reviewed using the analytical framework developed by the researchers. RESULTS: The quantitative research comprised 90.7% of the studies, whereas the qualitative research were 7.9% of them. Approximately 81.4% of those reviewed have publication dates spanning 2006 to 2015. Only 13.6% of the studies were conducted with the approval of an institutional review board. The subjects of studies were psycho-social health (151.8%), behavioral health (28.5%), cognitive health (15.0%), physical health (12.2%), integrated health (7.8%), and spiritual health (2.8%). Within the quantitative studies reviewed, the most commonly used study design was survey research (86.0%). The two sampling methods used most often were convenience sampling (53.5%) and snowball sampling (19.4%), and the most commonly used data-collection method were questionnaires (94.6%). As for the qualitative studies, the most commonly used study design was phenomenology. CONCLUSION: The results suggested that the reviewed studies focused on physical health more than psycho-social health, and physiological measurement more than questionnaires. Ethical considerations need to be expanded.

The purpose of this study is to provide the basic data and their analysis to improve hospital foodservice by identifying patient satisfaction with different attributes of hospital foodservice and its influencing factors using self written survey on nine hundred fifteen hospitalized patients in 28 general hospitals in Seoul and Kungki area. The statistical analysis of data was done by SAS/WIN package(Version 6.11) to determine Descriptive Analysis, T-test, Analysis of Variance, Pearson's Correlation, and Factor Analysis. The summary of the study results is as follows: 1. Among sixteen food-service quality attributes, the most unsatisfying one was the meal itself, the provision of nutrition informations, the possibility of menu choices, immediate response on meal problems, and the taste of the meal. 2. There was a positive correlation between the general quality satisfaction and freshness, nutritional considerations, and the temperature of the dishes and trays, and variety of menu in food-service quality were also correlated positively. 3. Based on the result of statistical analysis on the expectation and recognition in hospital food-service quality attributes vs quality satisfaction, expectation was negatively correlated with quality satisfaction: however, recognition was positively correlated.
