PURPOSE:Recent studies proposed that polyunsaturated fatty acids (PUFA) of the omega6 series (linoleic acid, LA) compared to the omega 3 series (linolenic acid, LNA) may be a potent promoters of adipogenesis during the gestation/lactation period. Increased ratio of LA/LNA may stimulate adipose tissue development during gestation/lactation period and may subsequently lead to chilhood obesity. The purpose of this study is to evaluate fatty acids composition of the breast milk in Korean lactating women and to analyze the relationship between LA/LNA and the body weight gain of the infants. METHODS:Fifty eight healthy postpartum lactating women and their healthy 58 breast feeding infants were studied. At 11.3+/-3.9 days of postpartum, breast milk were taken and analyzed by gas-liquid chromatography with one-step methylation method. RESULTS:The total fat contents in breast milk were 3.2+/-1.3%. The total fat contents in breast milk were not related to maternal BMI or Kaup index of infants. The percentage of PUFA was 24.9+/-6.0%. Among these PUFA, the percentage of LA and LNA was 20.3+/-5.8% and 2.2+/-0.8%, respectively. LA/ LNA ratio was 10.2+/-2.5. There were no significant correlations between LA/LNA ratio and infant weight gain during the first 2 months of life. CONCLUSION: Short term weight gain of infant was not related to the LA/LNA ratio in the breast milk. Further studies on the long term effects on fat percent and body weight of infants would be needed.

BACKGROUND: As many as several weeks of incubation may be necessary for the recovery of mycobacteria when conventional culture media are used. Previous studies evaluating Mycobacteria Growth Indicator Tube (MGIT) as a rapid for the growth and detection of mycobacteria from clinical specimens have been reported. We compared MGIT with Ogawa media for the recovery of mycobacteria from clinical specimens. METHODS: Ninety nine clinical specimens received in the laboratory of Wonju Christian Hospital from June to September 199 were used for this study. The specimens from nonsterile body sites were digested, decontaminated, and concentrated, for culture and Ziehl-Neelsen stain, and specimen were inoculated onto MGIT tube and 3% Ogawa egg medium, and cultured for 8 weeks. RESULTS: Of the 38 specimens culture-positive for mycobacteria, 3 grew isolates in MGIT medium only, 8 grew isolates in Ogawa media only, and 27 grew isolates in both media. Mean (median, range) times to detection of mycobacteria were 13.7 (5.5, 2-48) days with MGIT and 19.6 (18, 13-37) days with Ogawa (P>0.05). The number recovered with MGIT plus Ogawa media was 24 (63.2%) within 14 days of receipt of specimen, and 31 (81.6%) within 21 days. The contamination rates were 31 % for MGIT and 1 % for Ogawa media. CONCLUSIONS: MGIT appears useful to quickly detect and identify mycobacteria from clinical specimens. However, because the number of culture-positive specimen in MGIT was not greater than those recovered with Ogawa media, MGIT should be used in combination with solid media to reduce turnaround times and increase the isolation rate.

Proteinuria is common in pediatric and adolescent patients. Proteinuria is defined as urinary protein excretion at levels higher than 100-150 mg/m²/day in children. It can be indicative of normal or benign conditions as well as numerous types of severe underlying renal or systemic disease. The school urine screening program has been conducted in Korea since 1998. Since then, numerous patients with normal or benign proteinuria as well as early stage renal diseases have been referred to the hospital. Benign proteinuria includes orthostatic proteinuria and transient proteinuria. Most causes of proteinuria can be categorized into 3 types: 1) overflow, 2) tubular, and 3) glomerular. Although treatment should be directed at the underlying cause of the proteinuria, prompt evaluation, diagnosis, and long-term monitoring of these pediatric patients can prevent potential progression of the underlying disease process. This article provides an overview of proteinuria: its causes, methods of assessment, and algorithmic suggestions to differentiate benign from pathologic renal disease.

Purpose: Nursing stress on life-sustaining treatment of nurses is a significant contributing factor to nursing care performance and patient care outcomes. We need to investigate the factors associated with nursing stress on life-sustaining treatment in hospital settings. The purpose of this descriptive study was to examine the relationship of role perception of life-sustaining treatment and good death perception with nursing stress on life-sustaining treatment among nurses in hospital settings. Methods: Using a cross-sectional study design, we recruited nurses at a hospital located in a metropolitan city in Korea. The nurses completed structured questionnaire questions which were composed of well-validated questionnaires. Descriptive statistics and hierarchical multiple regression model were utilized for data analysis. Results: A total of 205 nurses participated in the study (female 93.2%; aged 20~29 years 63.0%; single status 78.5%). In the hierarchical multiple regression model, there was a significant positive relationship between role perception of life-sustaining treatment and nursing stress on life-sustaining treatment (β=.27, p<.001). Higher education level and working at a ward setting were also significantly related to nursing stress on life-sustaining treatment (β=.13, p<.046 for education level; β=.22, p=.001 for work setting). However, there was no relationship between good death perception and nursing stress on life-sustaining treatment. Conclusion Education programs to reduce nursing stress on life-sustaining treatment are needed to develop for nurses who have higher role perception of life-sustaining treatment with higher education level working at ward settings in hospitals.

BACKGROUND AND OBJECTIVES: Marfan syndrome is an autosomal dominant heritable disease of connective tissue which is characterized by cardinal features mainly in the cardiovascular, ocular and skeletal systems. Aneurysms or dissections of the aorta are the major cardiovascular complications of the disorder causing early mortality. Mutations in the fibrillin-1 (FBN1) gene on chromosome 15q21.1 have been found to be major causes of Marfan syndrome. The purpose of this study was to characterize the molecular defect in Korean Marfan patients, thus contributing to the effort of correlating the genotype with the phenotype. SUBJECTS AND METHODS: We screened all 65 exons of the FBN1 gene in 14 subjects diagnosed as Marfan syndrome by the method of single strand conformation polymorphism-heteroduplex analysis. RESULTS: We found mutations in only 10 among 14 patients. This study identified 8 novel mutations and 2 previously reported mutations in 14 Korean Marfan patients. Two cases were nonsense mutations and 8 were missense mutations, including 3 frameshift. Seven cases of the mutations occurred in one of the 43 calcium binding epidermal growth factor-like domains within an FBN1 gene. Mutations in Marfan patients occurred variably over the whole field of this FBN1 gene. CONCLUSION: Our results will contribute to the establishment of a database of Korean Marfan patients. Extending this study and using the database will help early detection of the disease and prevention of complications.

BACKGROUND: After the World-Wide-Web(www) appeared, history has abruptly fallen in the new era of the Internet. In Korea, after the first medical internet site appeared, there was a major development in the WWW. But the quality and quantity of the web-page remains in infancy. Therefore, through the analysis of the Korean medical internet sites on present status, directions for development of Korean medical internet sites can be made. METHODS: From April 1st, 1999 to June 30th, 1999 in the Korean web sites, we visited 1044 sites. They included "Medmark Korea" representing medical search engine, "Eulji medical library" in the Eulji Medical College Hospital, and the medical sites of the "Yahoo Korea", "naver.com", and "simmani.com". Through this internet search, the information about locations, first publication year, classification by characteristics of homepage, speciality, web service form was obtained. Among these sites, acquireing from insufficient source further, questions were sent to the webmasters of 143 websites by e-mail. The questions included 7 items on the characteristic of webmasters, 8 items on the general characteristics of internet sites, 8 items on the contents, and their own comments. RESULTS: The occupation of webmasters was as follows: were physicians 94.4%, were male. According to age distribution, those in their thirties was 48.2%, and forties, 33.3%. Amone the 521 websites confirmed, there were 44 sites in 199 151 in 1996, 237 in 1997, and 79 in 1999. According to the distribution of location, metropolitan areas including Seoul, Inchon, Kyonggi occupied 68.9% among total. The main portion of the intentional visitors was ordinary people comprising 39.2%, members 9.8%, and physicians 7.7%. Concerning the purposes of publication, 38.7% of websites intended for health education to citizens, 31.0% for publicity of hospital or organizations, and 15.5% for exchange of information between members. For the most significant contents, 26.6% focused on the common-sense health issues, 35.7% on exchange of special medical information, 8.4% on education data for medical students, and 13.3% on publicity of hospitals. For the update interval, 22.0% renewed their sites within 1 week, 22.7% in 1 month, 23.4% in 3 months, and 20.6% in 6 months. For the effectiveness of homepage, the rate of `good' and `very good' response was 52.8%. CONCLUSION: Our investigation, showed that medical internet sites are lead by those in their thirties and forties. Web sites was concentrated to metropolitan areas where informational infrastructure was well developed. It is emphasized that efforts to informationalization by are needed by, governmental medical database systems should be established, and that the guidelines which enables validity of medical information should be set forth.
