BACKGROUND: The aim of our study is to determine maximum surgical blood order schedule (MSBOS) in elective surgery through analyzing usage of blood products such as packed red cells and whole blood at Dankook University Hospital. We would like to establish the guidelines for effective utilization of blood products by introducing MSBOS to our hospital. METHODS: We calculated average amount of transfused blood for each elective surgery based on the discharge records of patients from January 1997 to December 1998 at Dankook University Hospital. Only those operations performed more than 5 times were included in this study. Average number of transfused units per patient of each operation was selected for MSBOS. RESULTS: For two years, the total number of surgery was 15,497 and the number of transfused operations was 1,682 (10.85%). Operation groups transfused below 10% was 77.3% of all 199 operation groups. The number of operation groups whose average of transfused blood was below 0.5 units was 80.3%. Type and screen (T&S) was recommended in 140 (70.4%) of all the operation groups. Of total groups MSBOS of 2 units was estimated in 4 groups (2.0%), of 3 in 14 groups (7.0%), 4 of 4 groups (2.0%), 5 of 2 groups (1.0%), 6 of 4 groups (2.0%), 7 of 7 groups (3.5%), and 8 in 2 groups (1.0%), respectively. CONCLUSION: We established MSBOS through the previous transfusion data of surgical operations over two years. To enforce MSBOS is needed for better medical services, which would decrease blood disuse and medical cost.

Epstein-Barr virus (EBV)-encoded small non-coding RNAs (EBERs) are abundantly expressed in various EBV-associated malignancies, and play critical roles in cell proliferation, tumorigenesis, and apoptosis resistance. However, the mechanism how EBERs regulate cell function awaits further clarification. In this study, we investigated the effect of EBERs on the expression of cellular microRNA (miRNA) and mRNA expression. To test the effect of EBERs while unaffected by other EBV genes, we used EBERs-deleted recombinant EBV infected Burkitt's lymphoma cell line (Akata(+)EBERs(-)) as well as EBV-infected (Akata(+)) and EBV uninfected (Akata(-)) cell lines. They all have the same genetic backgrounds. First, 15 different cellular miRNAs which have reverse complementary sequences to EBERs and have reported targets were selected by bioinformatics analysis. When RT-PCR was carried out for the 16 miRNAs using RNAs from Akata(+), Akata(-), and Akata(+)EBERs(-) cells, hsa-miR-7-5p was the only one showing down-regulated expression in Akata(+) than in Akata(-) and Akata(+)EBERs(-) cells. Bioinformatics and mRNA microarray analyses for Akata(+), Akata(-), and Akata(+)EBERs(-) cell lines were then carried out to predict putative targets of hsa-miR-7-5p. Among the 6 predicted targets of hsa-miR-7-5p, only low density lipoprotein receptor-related protein 6 (LRP6) was up-regulated in EBERs-expressing cells when tested by RT-PCR and Western blot. However, luciferase reporter assay showed that the 3'-UTR of LRP6 was not directly targeted by hsa-miR-7-5p. Our data suggest that both hsa-miR-7-5p and LRP6 are regulated by EBERs in Akata cells, and these genes may partly mediate the tumorigenic function of EBERs in Burkitt's lymphoma.

Verrucous carcinoma is a form of low grade squamous cell carcinoma that is characterized grossly by its exophytic and wart-like appearance. We experienced a case of verrucous carcinoma in a 63-year-old female patient who presented with pyelonephritis caused by staghorn calculi. Abdominal CT scan showed a renal pelvic mass and nephrectomy was done. Histologic examination showed extensive keratinizing squamous metaplasia of pelvic urothelium with an area of verrucous acanthosis. To our knowledge, this is the second case of verrucous carcinoma of renal pelvis that has been reported in literature. We describe a case and review the literature concerning verrucous carcinoma.

Apoptotic cell death induced by p53 occurs at a late G1 cell cycle checkpoint termed the restriction(R)point, and it has been proposed that p53-induced apoptosis causes upregulation of CD95. However, as cells with defective in CD95 signaling pathway are still sensitive to p53-induced apoptosis, CD95 cannot be the sole factor resulting in apoptosis. In addition, unlike p53-induced apoptosis, the relationship between CD95-mediated apoptosis and the cell cycle is not clearly understood. It would there-fore be worth investigating whether CD95-mediated cell death is pertinent with p53-induced apoptosis in view of cell cycle related molecules. In this report, biochemical analysis showed that etoposide-induced apoptosis caused the induction and the nuclear translocation of effector molecules involved in G1 cell cycle checkpoint. However, there was no such translocation in the case of CD95-mediated death. Thus, although both types of apoptosis involved caspase activation, the cell cycle related proteins responded differently. This argues against the idea that p53-induced apoptosis occurs through the induction of CD95/CD95L expression.

Acardiac fetus in triplet pregnancy is a very rare, fatal congenital anomaly that had not been reported in Korea. It only occurs in multiple gestations associated with placental vascular anastomoses between the affected fetus and its co-twin. The major complications associated with acardiac fetus in triplet pregnancy are congestive heart failure in normal pumping fetus, maternal polyhydramnios, preterm labor, intrauterine fetal death, etc, and perinatal diagnosis can be made with the perinatal ultrasonographic examination. We report a case of acardiac fetus in a spontaneous triplet pregnancy at 23 weeks of gestational age with a brief review of the literature.

PURPOSE: Reversible posterior leukoencephalopathy syndrome(RPLS) is a complex condition affecting gray/white matter of parieto-occipital lobes from multiple and different etiologies. This study was aimed to analyze clinical characteristics of this condition in Korean children. METHODS: A total of 36 patients from tertiary care medical centers were involved in the study. They were diagnosed as RPLS mainly by clinical and radiological manifestations. Their medical records and radiological features of brain MRI were retrospectively analyzed. RESULTS: Thirty six patients were involved in the study(21 males and 15 females, mean age: 9.8+/-4.1 years of age). Main underlying causes included drug induced(47%), renal diseases(28%), neurogenic tumors(8%) and so on. Initial manifestations were seizures, headache, visual disturbance, mental change, and nausea/vomiting. 13 patients(36%) had two or more symptoms. The brain MRI showed typical pattern of fairly symmetric, high T2 signal intensity in both parieto-occipital regions in 23 patients(64%) and various, atypical pattern in 13 patients(36%). 26 patients had the lesions affecting predominantly white matter, but 10 patients had the lesions affecting predominantly gray matter. 34 patients(94 %) had bilateral lesions, but 2 patients(6%) had unilateral lesion. This complex syndrome was associated with acute rise of blood pressure from a variety of conditions. A patient ended up a visual deficit despite the good prognosis. CONCLUSION: RPLS in Korean children seems to be complex, but a better understanding of this complex syndrome will lead to better clinical outcome by avoiding unnecessary investigations and appropriate management.

PURPOSE: This study was conducted to assess the effects of lights-out at nighttime on body weight, physiological variables, and behavioral status in premature infants and to provide basic data for applying lights-out at night time in premature infants. METHODS: Premature infants of over 32 weeks' corrected age were included in this study (January 2015-June 2015), and were allocated to two groups according to the lights-out at night for 5 hours: study group and control group. Lights-out was applied to the study group from midnight for five hours in a quiet environment. RESULTS: Fifty-two infants were included in the study: 26 in the study group and 26 in the control group. Growth rates of body weight, height, and head circumference were higher in the study group compared to the control group, but there were no statistical differences. In the physiological variables, heart rate decreased by 6.9 beats per minute in the study group, but it increased by 2.7 beats per minute in the control group (P<0.0001) during applied 5 hours at night. Anderson Behavioral State Score decreased in the study group compared to the control group (P=0.042). CONCLUSION: Lights-out at night decreased the heart rate and made the behavioral status more stable. To understand the effects of lights-out on long-term growth and development of premature infants at the highest risk of delayed growth and development, further studies with a larger number of premature infants are needed.

This study examined the job satisfaction of nutritionists, and its effect on organizational commitment andturnover intention in public health centers. The response data of 174 nutritionists were analyzed. The overallaverage of job satisfaction was 3.94 out of 7 points, which was determined to be below ‘normal’; however, thejob suitability of sub-factors scored 5.26, which was more than ‘normal’. The variables affecting job satisfactionthat were provided by the respondents included job-related licenses (P<0.01) and co-nutritionists (P<0.01).Organizational commitment ranked ‘normal’ with a score of 4.35. Normative commitment (4.90) of thesub-factors was ‘normal’ or more, and differed when considering ‘age’ (P<0.01), ‘employment status’ (P<0.01),‘salary per year’ (P<0.05), and ‘working area’ (P<0.05). The turnover intention was analyzed to be below‘normal’ with 3.88 points, and the variables affecting turnover were significantly higher for subjects in their20s (P<0.01), less than two job-related licenses (P<0.05), and less than two co-nutritionists (P<0.01). Thefour variables of job satisfaction, ‘business discretion’ (P<0.05), ‘work environment’ (P<0.01), ‘job suitability’(P<0.01), and ‘reward’ (P<0.01), positively affected the organizational commitment. Moreover, organizationalcommitment had a mediating effect (P<0.01) on job satisfaction and turnover intention. Taken together, ourresults suggest that public health centers need to develop improvement plans for business discretion, workenvironment, job suitability and reward.
