OBJECTIVE: The purpose of this study was to determine the reliability and usefulness of the lateral femoral cutaneous nerve conduction study by comparing the modified Ma's method (method I) with the method proposed by Spevak and Prevec (method II) and to develop a standard value of the Korean normal adult by the method II. METHOD: Twenty-nine healthy adults were examined for the lateral femoral cutaneous nerve conduction by both methods bilaterally. The nerve was stimulated 1 cm medial to anterior superior iliac spine (ASIS) in the method I and 8 cm distal to ASIS in the method II. The sensory nerve action potential was recorded with 8 cm long strip electrodes placed on the thigh 17 cm distal to ASIS in the method I and 33 cm distal to ASIS in the method II. RESULTS: 1) Among 58 extremities, a sensory nerve action potential was detected in 52 extremities (89.7%) by the method I and in 57 extremities (98.3%) by the method II without a significant difference between both methods. 2) The mean distal latency was 3.41 msec by the method I and 4.56 msec by the method II. 3) The mean amplitude was 7.24 microvolt by the method I and 6.63 microvolt by the method II without a significant difference between both methods. 4) The mean conduction velocity was 50.9 m/sec by the method I and 55.2 m/sec by the method II without a significant difference between both methods. CONCLUSION: According to the study, both methods are compatible and reliable for the examination of lateral femoral cutaneous nerve except for a significant difference in a mean conduction velocity.

Purpose: The diagnostic usefulness of fetal echocardiography in congenital heart disease is well known. One of the indications for fetal echocardiography is presence of extracardiac anomalies and such coexistent congenital heart disease may have important implications for obstetric and neonatal management. MATERIALS AND METHODS: 496 women with singleton pegnancies with amgenital anomalies that underwent penatal care and follow-up in Severance Hospital for 5 years from 1991 to 1995 were evaluated for the incidence of congenital heart disease. RESULTS: The incidence of congenital heart disease in fetuses with the associated extracardiac anomalies were as follows; central nervous system 6.9%(11/160), gastro-intestinal system 10.7%(8/75), genito-urinary sysem 4.7%(4/85), others 5.6%(4/72). Thirty-one of eighty-ane fetuses with congenital heart disease were found to have the associated extracardidac anomalies and ten of them chenoscenal abnormalities. CONCLUSION: We recommend that fetuses with congenital extracardiac anomalies sbould be checked for the presence of congenital heart disease and chmmosomal abnormalities, if needed.

We report 2 cases of pediatric DNTs which presented with intractable seizures and no other associated neurologic abnormalities. They showed typical appearance of DNTs on neuroimaging and histopathology. Most patients with DNT can be cured by surgical treatment with exellent outcome and do not need ratio- or chemotheraphy. This study indicates that it is quite important to consider DNTs as one of differential diagnoses in patients with intractable seizures especially when they present only with seizures without other neurologic symptoms.

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.

The Sertoli-Leydig cell tumor is a rare sex cord stromal tumor of the ovary, accounting for less than 0.5% of all primary ovarian neoplasm. This tumor is the most common type of all virilizing ovarian tumors. However, only one-third of patients develop virilization. Recently, we experienced a case of intermediately differentiated Sertoli-Leydig cell tumor with amenorrhea and so we present it with brief review of literature.

To check expert opinion about the investigation system of medicine-related death, model for "Death Investigation Center" was suggested and related questionnaire were requested. Between 15 December 2009 and 5 April 2010, we sent e-mails of the questionnaire which asked the opinion for the new postmortem investigation system. We sent the questionnaire to 3,289 lawyers and 4,523 doctors (total 7812), and received 100 replies out of the total. All the lawyers and doctors interviewed knew the importance of the postmortem investigation system. Most of them (87%) agreed to the introduction of the new postmortem investigation system. Some of them thought that protector's agreement was necessary for the postmortem investigation (21%), and more doctors were likely to participate with legal protocol (23%). If the postmortem investigation could not be performed due to the protector's disagreement, another specialized medical investigation should be needed to figure out the cause of death (85%). The new postmortem investigation system should be performed by the specific institution, and supported by the government (44%). In many expert's opinion, nonmedical experts such as lawyers and priests should be included for the institution of investigation for objectivity and neutrality (72%). This sample study finds that the postmortem investigation performed by specialized institution is necessary to determine the cause of death in the hospital. For the operation of the system, neutrality and the operating core would be the most important.

BACKGROUND: The aim of the study is to evaluate the difference of immunophenotypes of stromal cells between the pure phyllodes tumor (PT) type and the co-existent type of phyllodes tumor and fibroadenoma, and between benign and malignant PT. METHODS: Immunohistochemical staining for actin, CD34, CD10, c-kit, bcl-2, p53 and MIB-1 was performed using tissue microarray blocks that contained 25 cases of pure PT (16 benign tumors, 4, borderline malignant tumors, and 5 malignant tumors) and 6 cases of co-existent type. RESULTS: The expression rates of CD34 and MIB-1 in the pure PT type were significantly higher and the expression rate of actin in the pure PT was significantly lower than that of the co-existent type. However, there were no significant differences in the bcl-2, CD10, and p53 expressions between the pure PT type and the co-existent type, and no c-kit expression was observed in both types. No significant differences in the CD34, actin, bcl-2, CD10, and p53 expressions between the benign and borderline/malignant PT cases were found. However, a significant difference of the MIB-1 expression rate was noted. CONCLUSIONS: The stromal cells of the pure PT type are regarded as less mature myofibroblasts, and the CD10 reactivity in some phyllodes tumors suggests a myoepithelial origin. The MIB-1 labeling index would be useful for the grading of phyllodes tumor.
