BACKGROUND: The diagnosis of tuberculosis has been based on the detection of tubercle bacilli by acid-fast stain of smear or cultures, and recently the serologic diagnosis of tuberculosis has been provided a means of sensitive and specific detection of Mycobacterium tuberculosis. We evaluated the utility of enzyme immunoassay using determiner Tuberculosis Glicolipids(TBGL) antibody kit(Kyowa Medex Co. Ltd, Japan) to detect anti-TBGL antibody for diagnosis of pulmonary tuberculosis. METHODS: Anti-TBGL antibody assay was performed to the form 44 patients with active pulmonary tuberculosis(17 patients with smear positive, 7 patients with only culture positive, 20 patients with clinically active tuberculosis) and 80 controls (30 healthy controls, 24 patients with non-tuberculous respiratory diseases, 26 patients with inactive tuberculosis). We compared the sensitivity and specificity of anti-TBGL antibody with culture and AFB stain. RESULTS: Anti-TBGL antibodies were detected in 16 of 17(94%) smear positive patients, 4 of 7 patients with only culture positive and 16 of 20(80%) smear negative patients who had been clinically diagnosed as active pulmonary tuberculosis. Nine(35%) out of 26 patients with inactive tuberculosis, one(4%) out of 24 patients with non-tuberculous respiratory diseases and no one of healthy control had a positive antibody response. Overall sensitivity, specificity of the anti-TBGL antibody assay were 82%, 88%, respectively and sensitivities and specificities of culture and AFB smear 64%, 97%, and 49%, 100%, respectively. Anti-TBGL antibody titers in patients with active tuberculosis were significantly higher than control grup(P<0.05). Conclusions : The anti-TBGL antibody assay was sensitive, rapid and convenient. This assay will be useful as a tool for the diagnosis of tuberculosis in combination with other conventional methods.

BACKGROUND: The purpose of this study is to evaluate the evidence for the effectiveness of different isolation policies in reducing the incidence of methicillin-resistant Staphylococcus aureus (MRSA) infection in hospital in-patients. METHODS: We prospectively evaluated the effectiveness of an isolation policy on transmission of MRSA in the 745-beds hospital. First period, all patients with MRSA (March - July 2000) were not isolated Second period, strict isolation policies were performed (August 2000 - January 2002). All patients with MRSA were isolated in separated room, hand hygiene using alcohol handrub, gowning and g1oving, apply of MRSA notice sticker, criteria in isolation remove, separated disinfection and wastement. Third period, semi strict isolation policies were performed (February 2002 - August 2005). Some patients with MRSA were isolated in separated room and others were admitted in general ward for bed shortage. Only some practices were performed in hand washing and separated disinfection in general ward. RESULTS: The rates of MRSA nosocomial infection per patients during 1st, 2nd, and 3rd surveillance were reported 0.56, 0.23, and 0.42 (P<0.05). Patient-days rate of MRSA nosocomial infection during 1st, 2nd, and 3rd surveillance were reported 0.62, 0.27, and 0.38 (P<0.05). CONCLUSION: With many different isolation policies, it was possible to reduce nosocomial infection of MRSA. In this study, strict isolation policies (2nd period) were the most effective practices in reducing MRSA infection.

Medical school admission policies vary from country to country. In Korea, medical school admission policies reflect the policy choices made by the Ministry of Education. After the Korean War, universities implemented their own entrance exams, and since then, various admissions processes have been implemented with consideration of the fairness of the exam and the increase in private education expenses. The introduction of the medical graduate school system has led many universities to implement tests separate from the academic ability test. Currently, 40 medical schools have been approved by the government and are responsible for providing medical education, but there is a growing movement to open new medical schools in various regions. The excessive interest in medical school admissions in Korea is creating an unfavorable social atmosphere, where academies are even being operated for elementary school students to help them achieve an eventual goal of entering medical school. Furthermore, an irresponsible and sudden increase in the number of students admitted to medical school is causing a disruption in medical education. Medical schools need unconditional government support to strengthen their role in the community and the nation, and policy consideration is needed to ensure that universities are as autonomous as possible.

OBJECTIVE: This study examined the overall mental health consequences of the bereaved parents after the Sewol ferry accident. METHODS: Eighty-four bereaved parents participated in the study. Self-report scales assessing the severity of psychiatric symptoms and other related psychosomatic problems were used at 18 months following the accident. Univariate descriptive statistics and regression analyses were performed to report the prevalence, severity, and correlates of psychiatric symptoms. RESULTS: 94% of the participants appeared to suffer from complicated grief based on scores on the Inventory of Complicated Grief (ICG). Half of the participants were categorized as having severe depression and 70.2% reported clinically significant post-traumatic symptoms according to scores on the Patient Health Questionnaire-9 (PHQ-9) and PTSD Check List-5 (PCL-5). No significant differences by gender were observed in the severity of psychiatric symptoms. A higher educational level was associated with more severe psychiatric symptoms in fathers. CONCLUSION: The loss of a child due to a disaster caused by human error may continue to have a substantial impact on parental mental health at 18 months after the event. A longitudinal study following parents' mental health state would be necessary to investigate the long-term effects of the traumatic experience in the future.

BACKGROUND: The triple marker test with maternal serum during 15-20 weeks gestation, based on AFP, hCG and uE3, is a useful screening technique for detecting chromosomal abnormalities and neural tube defect (NTD). However, the false positive rate has been reported from 4 to 8%. The purpose of this study was to evaluate whether or not women with a false positive result of the triple marker screening are at an increased risk for adverse outcomes other than chromosomal abnor-malities and NTD. METHODS: The study population was derived from 5,622 women undergoing triple marker screening at Mokdong Hospital between January, 1997 and August, 1999. A false positive was defined as a positive result of the triple marker test without further evidence of NTD or chromoso-mal abnormalities. The study group included 83 women whose results were a false positive and the 129 controls whose results were negative. The adverse outcomes included preterm delivery (<37 weeks), premature rupture of the membrane, pre-eclampsia, a low weight for the particular gesta-tion age (<10 percentile), a congenital anomaly and fetal death. RESULTS: The false positive rate of the triple marker test was approximately 1.5%. The overall inci-dence of adverse outcomes in the women with false positive result and those with a negative result were similar (30.1% vs 30.2%, respectively) (P > 0.05). However, adverse outcomes such as pla-cental abnormalities (8.4% vs 2.3%) and congenital anomalies (7.2% vs 0.8%) were more frequent in the women with a false positive result than women with a negative result s (P < 0.05). CONCLUSIONS: The results suggest that false positive results of the triple marker screening test do not appear to be associated with an increased risk for an adverse pregnancy outcome, but a careful evaluation for the placental and fetal abnormalities is necessary.

A CD7 positive acute leukemia, lacking CD4, CD8, CD3, CD13 and CD33 expression may include 4 categories; acute T-cell leukemia, mixed lineage leukemia, acute undifferentiated leukemia and CD7 positive acute myeloid leukemia. Therefore, the expression of cyCD3 or the presence of TCR gene rearrangement can make the diagnosis of acute T-cell leukemia. We report a patient with acute T-cell lymphoblastic leukemia, showing CD7+, CD4-CD8-, and CD3-expression and TCR gamma gene rearrangement.
