BACKGROUND: HLA-B5102 is a newly approved antigen at the meeting of the WHO Nomenclature Committee held after the Eleventh International Histocompatibility Workshop. It had been called B5l.35 because it was defined by both B5l and B35 antisera. HLA-B5102 antigen cannot be accurately determined by current commercial HLA typing trays. This study was carried out to assess the frequency of HLA-B5102 antigen in Koreans and serological reaction patterns of HLA-B5102 on commercial HLA trays. METHODS: We performed HLA-A, B, C serological typing for 2,000 Koreans registered for KMDP (Korean Marrow Donor Program) donors using the Terasaki Oriental Tray (One Lambda, USA). Selected samples (17/2000) which showed atypical B5 reaction patterns were tested against Japan Central Block HLA Workshop tray to detect the presence of HLA-B5102. RESULTS: HLA-B5102 showed a phenotype (antigen) frequency of 0.45% (9/2000) and an allele frequency of 0.23%. Two locus HLA haplotype and linkage analysis showed that HLA-B5102 was in linkage disequilibrium with HLA-A3l (p<0.01). The serological patterns of HLA-B5102 on Terasaki Oriental Tray were 1) Lot 14, 15 : B5(+), 2) Lot 15 B : B5(+), B35+53(+), and 3) Lot 16 : B5(+), B5l(+), B35+53(+), and therefore could be identified as HLA-B5, B5l, B52, B35 or B53. CONCLUSIONS: The frequency of HLA-B5102 in the Korean population (antigen frequency 0.45%, allele frequency 0.23%) is similar to that of Japanese. The presence of HLA-B5102 can be suspected when atypical BS reaction patterns are encountered in commercial HLA typing trays, and B5 or BSI had better been assigned to these cases when additional confirmatory typing is not available.

PURPOSE: This study aimed to identify how an education program on palliative care affects nursing home caregivers' perception of hospice care and attitude towards terminally ill patient care. METHODS: This study was conducted using a nonequivalent control group with a pretest-posttest design. The participants were 101 certified care workers: 58 in the experimental group and 43 in the control. The experimental group completed the palliative care education program consisted of 20 hours of classroom training and 20 hours of clinical practicum. An ANCOVA was performed to compare the score changes to outcome variables. RESULTS: Compared with the control group, the experimental group showed significant pretest-posttest differences in both the perception of hospice care (F=21.09, P < 0.001) and attitude towards caring for terminally ill patients (F=13.28, P < 0.001). CONCLUSION: These results indicate that the palliative care education program for caregivers is effective in preparing participants to provide hospice/palliative care service. Further study is warranted to explore the effects of this program on palliative caregivers' performance.

Since the reemergence of tertian malaria in Korea in 1993, we have confirmed 10 cases of Plasmodium vivax malaria associated with blood transfusion from 1997 to 2001. Age of patients ranged from 4 months to 68 years; three cases were younger than 1 year old. Because 2 of 10 patients received different components of the same donor, 9 presumably infected donors were identified for the 10 cases. Four of them were identified by polymerase chain reaction, 2 by indirect fluorescent antibody test, and 1 donor was identified by peripheral blood film examination. Geographically the cases were distributed over the whole Nation; 3 cases in Seoul, 2 in Kyunggi and Ulsan, and 1 case each in Pusan, KyungNam and Taegu. The infective components were 1 unit of whole blood, 5 units of packed red cells and 4 units of packed platelets. The incubation periods ranged from 9 days to 78 days(mean : 30.5 days, median : 21.5 days). The incidence rate of transfusion-transmitted malaria From 1997 to 2001 calculated as number of cases/number of units of whole blood and packed red cells transfused during each year ranged from 0 to 2.85 cases per million units transfused. Enforced predonation counseling might have prevented some of the above cases. Although test for malaria antibody has been implemented for donor screening this method does not reflect the present infective status of donor. Therefore careful screening of donors according to the exclusion guidelines of the Korean Red Cross remains as the best way to prevent transfusion-transmitted malaria.

PURPOSE: This study was done to investigate the effects of a Stress Management Program providing Cognitive Behavior Therapy on problem-focused coping, job stress, and depression. METHODS: The research design was a quasi-experimental research with a nonequivalent control group pre-posttest. Participants were recruited from two fire safety centers in D city, and the research was carried out from March 11 to April 2, 2011. To test the effects of the Stress Management Program participants were divided into two groups, an experimental group (21) and a control group (20). The research tools included problem-focused coping, job stress, and depression scales. The Stress Management Program was provided to the experiment group for 60 minutes/session twice a week, for 4 weeks. Data were analyzed using Fisher's exact probability test, chi2-test, t-test with the SPSS/WIN 14.0 program. RESULTS: After attending the Stress Management Program, significant differences were found in problem-focused coping scores and depression scores between the experimental group and the control group (t=4.70, p<.001; t=-3.16, p=.003). But there were no significant differences in job stress scores between the two groups. CONCLUSION: The results indicate that the Stress Management Program providing Cognitive Behavior Therapy is an effective nursing intervention for improving problem-focused coping and decreasing depression in firefighters.

Surgical intervention in the posterior maxillary region requires detailed knowledge of maxillary sinus anatomy and the possible anatomical variations. This study evaluated the incidence, location of maxillary sinus septa by using radiographic (panoramic radiography and computed tomography) findings and comparison of panoramic radography with CT in antral anatomical variation. This study was based on data from 70 sinuses in partial dentate maxilla. The sample consisted of 61 patients(25 women and 36 men, with ages ranging between 19 and 77 years and a mean age of 49.4+/-11.3 years) who were being treatment-planned to receive implant-supported restorations. First, the panoramic images were examined for the presence of antral septa by radiologist and examiner who don't know about CT findings. And incidence of antral septa was evaluated using an axial plane of CT image. The incidence of septa was compared between panoramic radiography and CT. The accuracy of the incidence was compared between radiologists and dentists. A total of 20 septa were found in 70 sinuses on CT image and the prevalence of one or more septa per sinus was found to be 28.6%. The assumed incidence of septa on panoramic radiography was 27.6%+/-2.2% in radiologist and 31.9%+/-5.8% in dentists. Erroneous diagnosis rate was 11.42% in radiologist and 15.96% in dentists. 40% of antral septa were located in the anterior(premolar) region, 30% of septa were located in the middle(first molar) and posterior(second molar) region separately. Prior to implant placement, it seems appropriate to consider panoramic radiography as a standard radiographic examination and periapical radiographs may be used to complete the findings in regions not sharply depicted in the panoramic radiograph. And cross-sectional imaging should be used in sites with severe bone loss and close proximity of the maxillary sinus.

When thinking about priority setting in access to healthcare resources, decision-making requires that cost-effectiveness is balanced against medical ethics. The burden of disease has emerged as an important approach to the assessment of health needs for political decision-making. However, the disability adjusted life years approach hides conceptual and methodological issues regarding the claims and value of disabled people. In this article, we discuss ethical issues that are raised as a consequence of the introduction of evidence-based health policy, such as economic evidence, in establishing resource allocation priorities. In terms of ethical values in health priority setting in Korea, there is no reliable rationale for the judgment used in decision-making as well as for setting separate and distinct priorities for different government bodies. An important question, therefore, is which ethical values guiding the practice of decision-making should be reconciled with the economic evidence found in Korean healthcare. The health technology assessment core model from the European network for Health Technology Assessment (EUnetHTA) project is a good example of incorporating ethical values into decision-making. We suggest that a fair distribution of scarce healthcare resources in South Korea can be achieved by considering the ethical aspects of healthcare.

BACKGROUND: As the number of malaria patients has increased in Korea, the number of blood donors who are diagnosed as malaria after donation has also increased. And during 1997~2001, ten cases of transfusion-transmitted malaria were reported. We investigated the transfusion safety of blood that was donated by malaria patients before diagnosis. METHODS: For a total of 2,552 malaria patients diagnosed in 2001, blood donation history of past one year before diagnosis was inquired at the beginning of 2002. Then we inquired informations about recipients of the hospitals through the regional Red Cross blood centers. we also inquired development of malaria after transfusion for the recipients in the August of 2002. Malaria antibody test results of donated blood were also analyzed to determine the status of immunity of donors in Seoul, Gyeonggi and Gangwon area. RESULTS: Among 2,552 malaria patients, 162 (6.3%) patients had donated within one year before diagnosis and they were all man. Their blood was processed into 292 units of blood components and supplied to 90 hospitals, where it was transfused 286 patients. Among these 286 patients, no one was diagnosed as malaria until time of database retrieving. Among 162 malaria patient, enzyme immunoassay malaria antibody test results of 107 (66.0%) patients were available, and all were negative. CONCLUSION: No one has developed malaria among the recipients transfused with blood that was donated by malaria patients before diagnosis. Therefore, the infectivity of blood donated before malaria diagnosis is thought to be very low. As antibody to malaria was not produced in some of malaria patients before diagnosis, this finding could be useful for the study of immunology of malaria infection.
