The purpose of this study was to analyze and identify the higher-grade primary school children's needs for sexual education. We got the data with open question from 481 children from March to July 1999. We analyzed them according to the framework suggested by the Sex Information and Education Council of USA. The framework involves the six domains such as human development, relationship, personal skills, sexual behavior, sexual health, and society & culture. In the analysis of need for sexual education according to domain, need for human development was highest (79.2 %), after that followed society & culture (8.3 %), sexual health (5.8%), sexual behavior (3.6%), and relationships (3.1%). There was no need for personal skills. By topics, there were needs for puberty (38.0%), reproduction (32.5%), gender roles (6.0%), body image (4.9%), sexual abuse (2.4%) and reproductive health (2.4%). Girls and boys all mostly wanted to know human development 41.0 % and 38.2 % each. Society & culture (3.4 %), sexual behaviour (2.7%), sexual health (2.6%), relationship (2.4%) were domains selected by boys. Girls wanted to know society & culture (4.9%) and 'sexual health (3.2%). Comparing by grade, fourth, fifth and sixth grade children are commonly interested in development, society & culture. Fourth grade children scarcely show attention on the relationship, sexual behaviour and sexual health; meanwhile sixth grade children would like to know sexual behaviour and sexual health. When their grade became higher, they would like to know more precise, concrete and deep information. We suggest that the textbook/guidebook for sexual health for the higher-grade primary school children should be developed considering the sex and grade.

BACKGROUND: The knowledge about the nucleotides sequence of 9th chromosome that regulates the phenotype of ABO blood group has made the ABO genotyping possible. Since the genotyping can be done with only a small amount of DNA sample, it was primarily applied to the field of forensic medicine. When applied to the blood bank, it is useful in the resolution for ABO discrepancies between the cell and serum typing and determination of A and B subgroups. Rapid ABO genotyping using the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method and its value in determination of ABO subgroups is presented. METHODS: ABO genotyping was performed in seven patients and three families, seven were the cases of ABO discrepancies in routine ABO grouping and three families were for the confirmation of the ABO group. To identify the 261th nucleotide, a 252 bp PCR amplifed fragment was amplified by PCR and digested with Kpn I. For 703th nucleotide, a 128 bp PCR amplified fragment was designed and digested with Alu I. To determine the ABO genotype, the patterns of digestion in DNA fragment were examined. RESULTS: Among the seven cases of ABO discrepancies, B3 and Ael were two cases each. Weakened B due to leukemia was the one, and the other two cases were cis-AB and Am. The three families for confirmation of the ABO group were acquired B due to infection one family, cis-AB two families. CONCLUSIONS: ABO genotyping is a rapid and reliable method that can be used in the case of ABO discrepancies and determination of ABO subgroups.

OBJECTIVE: The aim of this study was to analyze a relation between the recurrence of cervical intraepithelial neoplasia (CIN) and the detection of high-risk human papillomavirus (HPV) DNA after loop electrosurgical excision procedure (LEEP), and to evaluate the clinical efficacy of HPV DNA test by Hybrid Capture Assay as a predictor of the recurrence of CIN after LEEP. METHODS: From January 2000 through March 2003, the charts of 238 women diagnosed as CIN and treated with LEEP were reviewed retrospectively. HPV DNA test (Hybrid Capture System I) for high-risk HPV was performed in all patients before LEEP. They were followed up with Papanicolaou smears and HPV DNA tests at the interval of 3 months during the first 6 months and then at the interval of 6 months. The Chi-square test was used for the statistical analysis. RESULTS: The rate of detection of high-risk HPV declined chronologically after LEEP. A higher recurrence rate was noted in the HPV DNA positive group after LEEP, comparing with the negative group, at 3 months (54.5% in positive vs. 6.5% in negative; p<0.05), at 6 months (61.1% in positive vs. 5.4% in negative; p<0.05), at 12 months (50.0% in positive vs. 14.0% in negative; p<0.05), and at 18 months (50.0% in positive vs. 15.2% in negative; p<0.05). The negative predictive value was high at 3 months (93.5%), at 6 months (94.6%), at 12 months (86.0%), and at 18 months (84.6%). There were significant associations between the recurrence of CIN and positive resection margin except for glandular involvements. CONCLUSION: The detection of high-risk HPV is a risk factor for the presence of CIN after LEEP. HPV DNA test by Hybrid Capture Assay after LEEP may be useful marker for the negative prediction of recurrence of CIN after LEEP.

OBJECTIVES: The aims of this study are 1) to determine if GAST is a better indicator in predicting ovarian response to COH compared with patient's age or basal FSH level and 2) to evaluate its role in detecting abnormal ovarian response. DESIGN : Prospective study in 118 patients undergoing IVF-ET using GnRH-a short protocol during May-September 1995. MATERIALS AND METHODS: After blood sampling for basal FSH and estradiol (E2) on cycle day two, 0.5 ml (0.525 mg) GnRH agonist (Suprefact, Hoechst) was injected subcutaneously. Serum E2 was measured 24 hours later. Initial E2 difference (deltaE2) was defined as the change in E2 on day 3 over the baseline day 2 value. Sixteen patients with ovarian cyst or single ovary or incorrect blood collection time were excluded from the analysis. The patients were divided into three groups by deltaE2; group A (n=30):deltaE2<40 pg/ml, group B (n=52): 40 pg/ml< or =deltaE2<100 pg/ml, group C (n=20): deltaE2< or =100 pg/ml. COH was done by GnRH agonist/HMG/hCG and IVF-EF was followed. Ratio of E2 on day of hCG injection over the number of ampules of gonadotropins used (E2hCGday/Amp) was regarded as ovarian responsiveness. Poor ovarian response and overstimulation were defined as E2 hCGday less than 600 pg/ml and greater than 5000 pg/ml, respectively. RESULTS: Mean age (+/-SEM) in group A, B and C were 33.7+/-0.8*, 31.5 +/-0.6 and 30.6+/-0.5*, respectively (*: p<0.05). Mean basal FSH level of group A (11.1+/-1.1 mIU/ml) was significantly higher than those of B (7.4+/- 0.2 mIU/ml) and C (6.8+/-0.4 mIU/ml) 0<0.001). Mean E2hCGday of group A was significantly lower than those of group B or C, i.e., 1402.1+/-187.7 pg/ml, 3153.2+/- 240.0 pg/ml, 4078.8+/-306.4 pg/ml respectively (p<0.0001). The number of ampules of gonadotropins used in group A was significantly greater than those in group B or C: 38.6+/-2.3, 24.2+/-1.1 and 18.5+/-1.0 (p<0.0001). The number of oocytes retrieved in group A was significantly smaller than those in group B or C: 6.4+/-1.1, 15.5+/-1.1 and 18.6+/-1.6, respectively (p<0.0001). By stepwise multiple regression, only deltaE2 showed a significant correlation (r=0.68, p<0.0001) with E2HCGday/Amp, while age or basal FSH level were not significant. Likewise, only deltaE2 correlated significantly with the number of oocytes retrieved (r=0.57, p<0.001). All four patients whose COH was canceled due to poor ovarian response belonged to group A only (Fisher's exact test, p<0.01). Whereas none of 30 patients in group A (0%) had overstimulation, 14 patients among 72 patients (19.4%) in group B and C had overstimulation (Fisher's exact test, p<0.01). CONCLUSIONS: These data suggest that initial E2 difference after GAST may be a better prognostic indicator of ovarian response to COH than age or basal FSH level. Since initial E2 difference demonstrates significant association with abnormal ovarian response such as poor ovarian response necessitating cycle cancellation or overstimulation, GAST may be helpful in monitoring and consultation of patients during COH in IVF-ET cycle.

BACKGROUND: Platelet refractoriness has been reported to occur in 30-70% of multitransfused patients. This can result by either immune or nonimmune mechanisms. The predominant immune cause of platelet refractoriness is alloimmunization to HLA class I antigens. Recently, acid-treated platelets have been used in a few patients with platelet refractoriness due to HLA alloantibodies. However, the effect of acid-treated platelets has not been consistent. The aim of this study was to evaluate the in vivo survival of acid-treated, HLA-eluted platelets in HLA-immunized rabbits. METHODS: For in vivo survival test, 14 New Zealand White rabbits were studied. Four rabbits were in the nonimmunized control and 10 were immunized by weekly transfusions of human pooled platelets for six weeks. The HLA-immunized group was separated into two groups with transfusion of acid-treated platelets and untreated platelets. The survival of transfused platelets in rabbits with immunization and control group was estimated by a flow cytometer using FITC-labeled anti-CD42a. We also examined the HLA re-expression in acid-treated platelets due to regeneration and adsorption of HLA from human plasma. RESLUTS: The half-life of untreated platelets in nonimmunized rabbits was 11.8 +/- 3.7 hr. The half-life of acid-treated platelets in rabbits with HLA antibodies was 9.5 +/- 5.5 hr and the half-life of untreated platelets in rabbits with HLA antibodies was 5.9 +/- 2.9 hr. The difference between untreated platelets in the nonimmunized control group and acid-treated platelets in rabbits with HLA antibodies was statistically insignificant (p=0.221). Re-expression of HLA-A,B,C by endogenous resynthesis occurred continuously, and after 24 hrs it reached 84% of pre-elution level. Adsorption of HLA antigens from human plasma was completed within four hrs. CONCLUSIONS: Acid-treated, HLA-eluted platelets may be applicable for the patients with refractoriness to platelet transfusion, especially, in case of unavailability of HLA-compatible donors and fatal bleeding such as intracranial hemorrhage and pulmonary hemorrhage. However, the post-transfusion increment of the platelet count could not be maintained over 24 hrs because of the endogenous resynthesis of HLA antigens.

BACKGROUND: Leukoreduced blood components are recommended for prevention of non-hemolytic febrile transfusion reactions, HLA alloimmunization, platelet transfusion refractoriness, and transfusion-transmissible diseases. In addition, prestorage leukoreduction may be advantageous to poststorage leukoreduction. The authors investigated the current status of usage of leukoreduced blood components in Korea. METHODS: We surveyed 2,373 medical facilities, where blood components were supplied from Korean Red Cross blood centers and/or Hanmaeum blood center during one year period between January and December 2009. The survey was conducted about the current situation of usage of leukoreduction by web-based program (http://bms.cdc.go.kr), and 743 facilities answered and were analyzed. RESULTS: The leukoreduced RBC components comprised 10.3% (prestorage leukoreduction, 91,066 units, 5.7%; poststorage leukoreduction 73,192 units, 4.6%) of the total 1,593,098 units of RBC components used in 743 medical facilities. The leukoreduced platelet concentrates comprised 33.1% (458,552 units) of the total 1,386,184 units of platelet concentrates used in 397 medical facilities. If 1 single donor platelet is counted as 6 platelet concentrates, 48.9% of the total platelet components used were leukoreduced. CONCLUSIONS: The proportion of leukoreduced blood components to the total blood components used in Korea was much lower than that in Unites States of America, especially lower in the use of prestorage leukoreduction of RBC components. Further studies are required for cost-effectiveness and demand-supply amounts of leukoreduced blood components, and appropriate prestorage leukoreduction has to be performed in Korea based on these studies.

PURPOSE: Cancer is the most frequent cause of death in Korea. Cancer screening can save lives through early detection. This study was to investigate major cancer screening rates and the reasons for not having been screening. METHOD: 210 participants of registered nurses from 5 general hospitals in Busan, Korea were completed a structured self-administered questionnaire. Data were analyzed using descriptive statistics with SPSS WIN 10.0. Results: The cancer screening rates of the subjects were 53.8% in Pap smear test for cervical cancer, 41.0% in gastroendoscopy for stomach cancer, 15.7% in mammograpy for breast cancer, and 3.8% in colonoscopy. And the higher proportions of having regular screening were 9,5% in Pap smear test and 2.9% in gastroendoscopy. The primary reason related to not having a screening test was 'seems to be healthy'. CONCLUSION: The findings showed the necessity of recognizing and educating Korean nurses to have a regular cancer screening for their health management.

PURPOSE: The prognosis of advanced colorectal cancer patients may be different even for the same TNM staging. The characteristic features of tumors, such as tumor budding, tumor nodules, and extracapsular extension (ECE) of lymph nodes, can influence the disease progression and the outcome for patients. Tumor budding occurs what at the invasion front of colorectal adenocarcinomas, tumor cells, singly or in small aggregates, become detached from the neoplastic glands, and it can be divided it into two groups, low grade (0~16 foci in a field) and high grade (17 or more foci in a field). A tumor nodule is histologically identified within the fatty tissue or the detached fatty tissue around the dissected lymph nodes, or is a place picked up as lymph nodes from resected specimens which contain no lymph node components. ECE is defined as a tumor extension beyond the node capsule. The aims of this study were to evaluate the clinical significance of tumor budding, tumor nodules, and ECE of lymph nodes as prognostic factors in Stage III colorectal cancer patients. METHODS: We analyzed the disease-free and overall 5-year survival rates and recurrence rates in 94 Stage-III colorectal cancer patients according to tumor the budding intensity, the tumor nodules, and the lymph node ECE status. RESULTS: Of the entire group, the 5-year disease-free and overall survival rates were 49%, and 50%, respectively. The 5-year disease-free and overall survival rates were higher in the low-grade tumor budding group than in the high-grade group (58% vs 33%, P=0.045, 61% vs 39%, P=0.003). The 5-year disease-free and overall survival rates in patients with tumor nodules were lower than those in patients without one (44% vs 69%, P=0.086, 47% vs 77%, P=0.018). The recurrence rate was also higher in the group with tumor nodules than without one (80% vs 52%, P=0.045). The 5-year disease-free and overall survival rates were higher in the ECE negative group than in the positive one (68% vs 37%, P=0.018, 75% vs 42%, P=0.001). The recurrence rate was also higher in the ECE positive group than in the negative group (78% vs 46%, P=0.008). The existence of ECE and tumor nodule were strongly related to systemic recurrence (P=0.006, P=0.033), but not to the local recurrence (P=0.777, P=0.611). Considering the analysis of the recurrence pattern by N stage classification, there is no statistical difference in the N2 patient group, but there was in the existence of ECE and tumor nodule were strongly related to the systemic recurrence in N1 group (P=0.019, P=0.028). These three factors were scored according to the existence, and the score range was divided into two prognostic groups, high risk group (> or =2) and low risk group (<2). The high risk group was significantly associated with systemic recurrence (P= 0.004) rather than recurrence (P=0.865), and these score value were only significant in the N1 patient group (P=0.007) rather than in the N2 group (P=0.927). The high risk group also showed poor overall survival rate compared with the low risk one in only the N1 group (P=0.002), but nof in the N2 group (P=0.193). On multivariate analysis, UICC stage and ECE were two significant factors for tumor recurrence and the 5-year disease-free survival rate. CONCLUSIONS: These data showed that even if similar lymph node metastasis existed in advanced colorectal cancer patients, there was a different 5-year disease-free survival rate and overall survival rate according to the tumor budding, tumor nodule, and ECE status. On multivariate analysis, UICC stage and ECE were two significant factors for the tumor recurrence and the 5-year disease-free survival rate. Our results suggest that tumor budding, tumor nodule, and ECE of lymph node are excellent parameters to provide a confident prediction of clinical outcome.
