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: Typhoid fever, caused by Salmonella enterica serotype Typhi, remams an important public health problem in Korea, and asymptomatic chronic carriers play a role in the endemicity. However, the molecular studies of S. typhi isolates are very limited. We characterized clinical isolates of S. typhi by molecular and phage typing tools for the extent of genetic diversity and relatedness among the isolates. METHODS: A total of 49 S. typhi isolates from sporadic cases of typhoid fever were collected in 3 university hospitals in Seoul during 1992 to 1998 and examined for in vitro susceptibility to 14 antimicrobials by disk diffusion method, ribotyping using PstI restriction enzyme, and pulsed-field gel electrophoresis (PFGE) using XbaI and Vi phage typing. The distribution of the epidemiological types and genomic DNA relatedness were analyzed. RESULTS: Forty-five out of 49 isolates were susceptible to all drugs tested. Thirty-two out of 47 were typable by phage typing and 56.3% possessed the phage type El or Ml. Forty-nine isolates divided into 6 different ribotypes (A to F) and 19 different PFGE types (AO through A17, BO) by ribotyping and PFGE analysis, respectively. Based on the 3 typing systems, 32 isolates divided into 17 different epidemiological types. The E1-A-A12 (phage type-ribotype-PFGE type) was most prevalent (18.8Fo) and isolated only in 1998, but distributed in various areas of isolation. The next prevalent M1-A-A1 (15.6%) was isolated from 1992 through 1998. The genetic relatedness based on PFGE analysis revealed that F (coefficient of similarity) values are 0.64 to 1.0 and 0.52 for A subtypes and BO type, respectively. CONCLUSIONS: We conclude that the circulating S. typhi strains in Seoul city show considerable genetic diversity, whereas most of them seems to be clonally related.
