Microvillous inclusion disease (MID) or congenital microvillous atrophy is a rare cause of intractable, persistent secretory diarrhea shortly after birth or at birth. The prognosis of MID is very poor and most of the reported patients have died within 6.5 years. Diagnosis is based on the ultrastructural demonstration of intracytoplasmic inclusion of microvilli. There have been several cases reported in the literature. To evaluate the clinicopathologic features of MID, we have reviewed 4 cases of MID which was confirmed by the ultrastructural study of the duodenal biopsy. All patients suffered from life-threatening diarrhea since birth. Many other radiologic or laboratory findings were of no value in the evaluation of causative agents. One of the patients died of the disease and remaining patients have been alive on intravenous fluids or total parenteral nutrition. Histological findings of all cases were similar and characterized by varying degrees of mucosal atrophy and chronic inflammatory cell infiltration in the duodenal mucosa. PAS stain revealed a discontinuous brush border over the atrophic villous surface with or without small vacuoles in the cytoplasm of the surface epithelium. Ultrastructural changes were found mainly in the surface epithelium of the duodenal mucosa and characterized by the presence of membrane bound inclusions lined by intact or degenerating microvilli, as well as degeneration of surface epithelial cells with loss of microvilli, or with sparse, short microvilli.

BACKGROUND: Coagulase negative staphylococcus (CNS) spp. is a major pathogenic organism of nosocomial and community-acquired urianry tract infections, and causes infrctions in the immunocompromised host, and in particular, bloodstream infetions in patent with indwelling devices. High prevalance of methicillin resistance has been noticed in CNS which also have been recongnized as an important multidrug resistant pathogen. The optimal phenotypic method for detecting methicillin resistance still remains controversial, and new guidelines for detecting methicillin resistance of CNS was proposed by NCCLS in January 1999. We evaluated the relationship between mecA gene by PCR method and antimicrobial susceptibility tests according to the new NCCLS guidelines. METHODS: A total of 82 CNS isolates were examined for MICs and penicillin MICs by disk diffusion and agar dilution method according to NCCLS guidelines, and detections, and detection of mecA gene by PCR. RESULT: In disk diffusion method, 66 strains (80.5%) and 63 strains (76.8%) showed resistance to penicillin and oxacillin, respectively, and in agar dilution method, 71 strains(86.6%) and 53 strains (64.6%), respectively. In PCR method, mecA genes were detected in 49 strains(59.8%). Comparing with mecA gene detection by PCR method, the sensitivity of disk diffusion and agar dilution method was 95.8% and 89.8%, repectively. However, the sensitivity of disk diffusion and agar dilution method was 65.3% and 75.5%, respectively using previous NCCLS criteria. CONCLUSION: The new criteria of NCCLS detects the methicillin resistance induced by mecA gene more sensitively than previous one.

The purpose of this study was to survey basic data for management of elderly day care centers. In this study. occupation. leisure life. and food. clothing and habituation. as well as social relationship. health state and behavior. and general characteristics of subjects were examined to identify the factors affecting their cognition. need and preference of the day care centers. The subjects of this study were 392 elderly. aged 60 years or over. living in Gangnung and neighboring districts. Data were collected by educated interviewers from November 4 through Novemver 22, 2002. The subjects were interviewed face to face. one for one after the interviewee's agreements on the survey. The collected data were analysed with logistic regression analysis by SAS (statistical analysis system). Logistic regression analysis was done to identify affecting factors for cognition. need and preference of the elderly day care centers. The major findings are as follows: 1. The factors affecting cognition for care centers were analysed. The the day subjects with an occupation and a lower satisfaction level of living environment and friendship. who were economically secure enough to manage a sudden accident. showed a higher level of cognition of the day care centers. The subjects with a higher level of mental health state and a lower level of IADL also showed a higher level of cognition. On the general characteristics younger female subjects showed a higher level of cognition. 2. The subjects with a lower level of perceived economic condition who did not own their housing and were not economically safe enough to manage a sudden accident. had showed a higher level of need for the day care centers. It showed that the subjects with a high level of mental health state. a bad eye sight and dental condition. a good perceived health condition. and a lower level of IADL. needed the centers. 3. The subjects who had an occupation, however, not capable of making their own daily expenses. and a low occupation satisfaction level. and who did not own their housing. and were economically poor not enough to manage a sudden accident. showed a higher preference for the day care centers. The subjects with higher levels of friendship satisfaction and perceived health condition. not living with their spouse. and a higher education level, showed a higher preference for the centers. In conclusion. the common factors affecting their cognition. need and preference of the day care centers were occupation, economic security enough to manage accidents. and friendship satisfaction level. Especially, the subjects who had an occupation, however. not economically secure enough to manage accidents. and who did not live in their own housing with a good perceived health condition, showed high levels of need and preference for the day care centers. These results can be used as basic data to develop the efficient elderly day care centers, thus contribute to the elderly welfare in a local community.

The objective of this study was to apply a dementia prevention program to the subjects who were suspected of dementia and test its effect. This study was one group pretest-posttest design. The dementia prevention program was applied for 20 weeks to the 19 subjects who were suspected of dementia after a screen test among 638 subjects enrolled in 10 senior citizen's centers in G city. The scores of measured before and after the program. The data collected were analyzed using a SPSS (statistical analysis system) program, and frequencies, averages and standard deviations were obtained. The differences of the scores of the pretest and posttest were analyzed with Mann-Whitney test and sign test. The results were as follows: 1. After the program, the average score of self-efficacy was increased from 75.31 (standard deviation 11.99) to 84.26 (standard deviation 13.92). 2. There are no differences between the average scores of physical and psychological quality of life, however, the average score of social quality of life was slightly increased from 2.25 (standard deviation 0.40) to 2.53 (standard deviation 0.43), and the overall score of social quality of life was low. 3. The average score of cognition was significantly increased from 21.00 (standard deviation 2.60) to 24.58 (standard deviation 3.37), thus, it was found that the program was effective to improve the cognition level. 4. The score differences of self-efficacy, quality of life, cognition between the pretest and posttest were statistically significant. 5. The score differences of quality of life between the pretest and posttest were found to be dependent on marital status, exercise and regular chechup yes or no. In conclusion, the program was effective to prevent the subjects suspected of dementia from dementia.

A set of exposure factors that reflects the characteristics of individual behavior capable of influencing exposure is essential for risk and exposure assessment. In 2007, the Korean Exposure Factors Handbook was, therefore, issued, driven by the need to develop reliable exposure factors representing the Korean population. The purpose of this study was to overview the development process of the Korean Exposure Factors Handbook and major recommended exposure values for the Korean population to allow information exchanges and comparison of recommended values among nations. The researchers reviewed the domestic data that could be used in the development of exposure factors, confirmed a knowledge gap, and set a priority of development by phases. A methodology to measure exposure factors was established to develop measuring techniques and test their validity. Data were processed or a survey was conducted according to the availability of data. The study thus produced recommended values for 24 exposure factors grouped by general exposure factors, food ingestion factors, and activity factors by setting up a database of exposure factors and carrying out statistical analysis. The study has significantly contributed to reducing the potential uncertainty of the risk and exposure assessment derived by the application of foreign data or research findings lacking representativeness or grounds by developing a set of exposure factors reflecting the characteristics of the Korean people. It will be necessary to conduct revisions in light of the changing statistical values of national data and the exposure factors based on Korean characteristics.

BACKGROUND: The rapid emergence of multi-drug resistant pneumococcal strains has heightened the importance of reliable and convenient susceptibility testing methods. The newly-developed VITEK-2 (bioMerieux, Inc., Hazelwood, MO, USA) System includes the capability of performing rapid susceptibility testing of Streptococcus pneumoniae using specially configured cards. The objective of this study is to evaluate the performance of the VITEK-2 System for susceptibility testing of S. pneumoniae. METHODS: One hundred clinical strains of S. pneumoniae (18 penicillin susceptible strains, 32 intermediate strains, and 50 resistant strains) were tested, which had been isolated in Samsung Medical Center. Minimum inhibitory concentrations (MICs) for penicillin, cefotaxime, erythromycin, ofloxacin, chloramphenicol, tetracyclin, and vancomycin were determined by broth dilution method and VITEK-2 System using AST-P506 cards. The results obtained by VITEK-2 System were compared to those obtained by broth dilution method. RESULTS: Overall agreement of MICs determined by two methods was 93.0% within the range of one dilution. The best agreement was achieved with vancomycin (100%), and in descending order, 99% with ofloxacin, 97% with erythromycin, 94% with chloramphenicol, 89% with cefotaxime, 88% with tetracycline, and 85% with penicillin. There were 1.9% of very major error, 2.0% of major error, and 8.6% of minor error. The mean time for generation of susceptibility results was 9.6 hours. CONCLUSIONS: VITEK-2 System provided rapid and reliable determinations of susceptibility category for most antibiotics and would be helpful as a substitution of existing MIC methods.

Objectives: This study was conducted to examine the obstacles in the use of healthcare from the perspective of family caregivers based on their experience of mental healthcare services and to identify practical recommendations according to the family’s needs. Methods: A focus group interview was conducted with 59 family caregivers of patients with mental disorders. They were asked about the first moment when they took the patient to a psychiatric hospital, their feelings, and experiences during the treatment, relapse or readmission, access to healthcare and obstacles. The results were analyzed in a three-step procedure using grounded theory analysis. Results: The results showed that the social prejudice and stigma toward mental disorders experienced by the family caregivers hindered the initial treatment approach. Discrimination and disadvantages in healthcare, and poor access to community mental healthcare services, lowered the reliability of institutions and services. A decrease in the sense of healing due to distrust in the treatment and disruption of family life can lead to a vicious circle that affects the continuity of treatment and could result in issues such as the stopping of treatment or difficulty in accessing treatment in case of relapse. Conclusion Based on these results, policy tasks were proposed to improve accessibility to mental health services according to the needs of the patient’s family.

Infantile fibrosarcoma is a rare malignant soft tissue tumor occurring especially in newborn and young children under 2 years. We experienced three cases of infantile fibrosarcoma presenting in the neonatal period. Case 1 presented with a multiseptated cystic mass on his left thigh at birth that was diagnosed as lymphangioma. After picibanil injection, we noted the size of the mass doubled and a solid lesion was prominent in the magnetic resonance image. Case 2 was found to have a reddish mass on his lower back mimicking hemangioma. Over 2 weeks, the mass grew rapidly with internal hemorrhaging. Case 3 was noted to have an encircling mass around the splenic flexure, which developed into congenital bowel obstruction. All of the tumors were resected completely, but microscopic resection margin was not clear in two patients. The two patients received adjuvant chemotherapy and all patients are well without evidence of recurrence.
