BACKGROUND: Family physicians should actively carry out adult immunization. DM is a common risk factor of influenza and pneumococcal pneumonia related complications, so DM patients should receive influenza and pneumococcal vaccinations. The authors investigated recognition and performance of influenza and pneumococcal vaccination among DM patients. METHODS: We surveyed knowledge and performance of influenza and pneumococcal vaccination among the 203 diabetic patients living in Seoul and responding to telephone interview, who visited one DM center in general hospital from March 3, to March 7, 1997. RESULTS: Among 203 DM patients, the risk factors for influenza and pneumococcal pneumonia other than DM were old age of 65 or over(35.0%), cardiovascular diseases(5.9%) and chronic pulmonary diseases(4.9%). The recognition rate and performance rate of influenza vaccination were 27.6% and 21.2% respectively, there was a statistically significant relationship between these rates(P<0.01). Those vaccinated 43 patients for influenza knew the need of vaccination through family members and relatives(58.1%) and through medical doctors(32.6%). Although 85.2% of 203 DM patients answered that they received education about need of vaccination through DM education program conducted at hospitals, but only 9 patients(4.4%) recognized well. The reasons for not performing influenza vaccination were lack of knowledge(63.1%), no experience of influenza(12.5%), 'forget for the moment(5.0%) and regard injection as a nuisance(2.5%) in descending order. The recognition rate and performance rate of of pneurnococcal vaccination were all zero percents. The reasons for not performing pneumococcal vaccination were lack of knowledge(91.1%) no experience of pneumococcal pneumonia(6.4%), regard injection as a nuisance(1.5%) and forget for the moment(1.0%) in descending order. CONCLUSIONS: The recognition and performance rates of influenza vaccination were low and those of pneumococcal vaccination were all zero percents among DM patients because they did not recognize well the need of these vaccinations. Therefore, the doctors who see DM patients should actively recommend influenza and pneumococcal vaccination and DM educational programs must include education for these vaccinations.

Agar-gel diffusion test (AGD), counterimmunoelectrophoresis (CIEP) and enzyme-linked immunosorbent assay(ELISA) were examined with the sera of skin test positives for paragonimiasis. The crude antigen(Paragonimus whole worm extracts: protein concentration, 7.56mg/ml) and human sera were used in AGD and CIEP. And in ELISA test, diluted antigen with 1:40,000 of crude antigen and diluted sera with 1:100, 1:200 were used in the test. The positive identical ratio between AGD and CIEP reactions is 98 percent and negative identical ratio is 100 percent. One or three precipitin bands are observed in AGD. One to seven precipitin bands are also revealed in CIEP. Especially, deeply stained bands are observed in CIEP than those of AGD. The positive identical ratios between AGD and ELISA tests are 96 percent in 1:100 diluted sera, and 94 percent in 1:200 diluted sera. But the negative identical ratios between AGD and ELISA tests are 97 percent and 99 percent respectively in 1:100 and 1:200 diluted sera. The positive identical ratios between CIEP and ELISA tests are 98 percent and 96 percent respectively in 1:100 and 1:200 diluted sera, but also 97 percent and 99 percent in 1:100 and 1:200. Control sera, such as clonorchiasis, amoebiasis and toxoplasmosis, revealed all negatives with Paragonimus antigen in AGD, CIEP and ELISA tests. By above results, ELISA was most sensitive, next CIEP and AGD. But AGD test appears to be more useful when used to crude antigen without cross reaction with other parasitic infections. CIEP test is basically equal in terms of precipitin reaction, but CIEP is able to be detected more sensitively and rapidly though less simple in handiwork than AGD. Consequently, three methods for immunological tests of paragonimiasis have good correlations with one another. Also, each of these has both merits and demerits in immunological test for paragonimiasis. But the ELISA test was proved to be the most sensitive and convenient tool for mass screening test, especially in case of using purified antigen.

BACKGROUND: Blood supply circumstances in Korea have changed in recent decades because of blood supplier diversification and restructuring of hospital blood donation centers. The purpose of this study is to understand the current status of hospital blood donation centers and their satisfaction levels with the Korean Red Cross Blood Center (KRCBC) and compare with the previous results for sustainable development of the blood supply system. METHODS: During one month in November 2014, we conducted a questionnaire survey through e-mail in 64 hospital blood donation centers which are approved by government. The response rate was 97% (62/64 hospitals). Responses from 62 hospitals were analyzed. RESULTS: The number of hospital blood donation centers were reduced by half from 129 in 2004 to 64 in 2014. There was no blood donation center in hospitals less than 400 beds, except 2 hospitals; 23 hospital (37.1%) blood banks collected no blood components. More than 80% of hospitals were satisfied with the KRCBC service such as donor record lookup and nucleic acid amplification Test (NAT) results lookup. Hospitals with more than 1,000 beds replied that they would not take account of transferring the collection services to KRCBC because of the directed and autologous donation and unexpected emergency blood transfusion. CONCLUSION: The government should be the subject of national blood policy and establish a committee or agency for its comprehensive and consistent execution through close cooperation with the KRCBC and hospitals.

BACKGROUND: The Korean Blood Safety Commission has implemented external proficiency testing (PT) for blood grouping test (BGT) since 2011. We analyzed the results of 2015 PT for BGT including hemagglutination grade for ABO BGT to help in planning the future PT for BGT and improving the quality of blood centers (BC). METHODS: Two kinds of whole blood survey samples composed of three panels for ABO grouping and three panels for D typing were sent to 68 institutes. Evaluation criteria for BGT were as follows: 'Good' for the answers matched with intended results, 'Acceptable' for the consensus answers other than that of 'Good', 'Unacceptable' for the answers other than those of 'Good+acceptable' as correct answers. RESULTS: The answer rates of 'Unacceptable' for ABO BGT were 0% for A(A1) antigen (Ag), 1.5% for B Ag, and 1.5% for ABW (A2BW) Ag, 15% of blood centers were graded as 'Acceptable' for ABW (A2BW) Ag because they could not detect BW Ag. All answers for D typing were 'Good' except one institute reported wrong switched results as D positive and D negative. Hemagglutination grade for ABO BGT varied from 77.2%~100% depending on blood groups and laboratories. CONCLUSION: Because some hospital BC could not detect BW Ag and there was a clerical error, continuous education should be required, and comparison of hemagglutination grade for ABO BGT of each BC would be helpful in improving quality of BC.

OBJECTIVES: The aim of this study was to evaluate the effect of red vinegar drink on sound enamel surface. METHODS: Commercially available red vinegar drink was used for the study. Firstly, pH values were measured in commercially available red vinegar drinks. Secondly, four groups; mineral water as the control group and red vinegar drink, red vinegar drink + mineral water (mixing ratio, 1:3), red vinegar drink + milk (mixing ratio,1:4) as the experimental group were selected. Forty specimens of bovine teeth were made and then divided into the four groups and treated with the test drinks for 1, 15, 30 and 60 minutes. The surface microhardness (vickers hardness number, VHN) was measured using the microhardness tester before and after the treatments. The surface of specimens was observed with Scanning Electron Microscopy (SEM). RESULTS: The average pH of red vinegar drinks was 2.91+/-0.02. The change values (before treatment - after treatment of surface microhardness of enamel surface) were significantly difference among groups (P<0.05). There was no significant difference between control and red vinegar drink + milk (1:4) and there was the significant difference between control group and red vinegar drink groups, and control and red vinegar drink + mineral water (1:3) groups. In SEM, damage of enamel surface was observed in Red vinegar and Red vinegar+Mineral water group. CONCLUSIONS: The results showed that the all experimental red vinegar drinks, except red vinegar drink + milk (1:4) can reduce the surface microhardness of sound enamel. Thus, it is suggested that the red vinegar drink with milk could be recommended the preventive eating method for reducing the risk of dental erosion on the red vinegar drink diet.
