Patient records from the Guam Cancer Registry were compared with patients listed in a health department viral hepatitis case registry and the numbers of liver cancer and viral hepatitis cases were compared by ethnicity. Hepatitis C was the form of viral hepatitis most common among liver cancer cases on Guam (63.3% of viral hepatitis-associated liver cancer cases). Since viral hepatitis is an important cause of liver cancer, studies such as the present one may provide the information necessary to establish programs (screening of populations at risk and infant vaccination in the case of hepatitis B, for example) that may lessen the impact of liver cancer in the future.

본 연구는 치위생과 학생을 대상으로 B형간염에 대한 건강신념의 차이를 파악하고 HBV 예방접종에 영향을 미치는 요인을 규명함으로써 B형간염 예방에 대한 보건교육의 기초자료를 제공하고자 한다. 경상도 지역에 소재한 3개 대학에서 재학 중인 임상현장 실습을 앞 둔 2 3학년 281명을 대상으로 2013년 4월 22일부터 5월 3일까지 자기기입식 설문조사를 실시하여 수집한 자료를 분석하여 다음과 같은 결론을 얻었다. 일반적 특성 및 B형간염 관련특성에 따른 예방접종 상태를 알아본 결과 학년에 따라 예방접종주사를 맞은 경우는 3학년 129명(71.3%), 2학년 45명(45.0%)으로 3학년의 예방접종률이 높게 나타나는 것을 확인할 수 있었다(p<0.001). 과거 B형간염에 대한 교육경험에 따라 예방접종주사를 맞은 경우는 경험이 있는 경우 87명(71.3%), 경험이 없는 경우 87명(54.7%)으로 교육경험이 있는 경우 예방접종률이 높게 나타났다(p=0.017). 학년에 따른 B형간염에 걸릴 가능성이 있다고 믿는 감수성은 3학년이 2.54로 높았고, B형간염에 관한 장애감은 2학년이 3.50으로 3학년 2.88 보다 통계적으로 유의하게 높게 나타났다(p<0.05). 건강신념 중 심각성과 예방접종 간에는 유의한 양의 상관이 있었고(r=0.179, p=0.003), 장애감과 예방접종 간에도 통계적으로 유의한 음의 상관이 있어(r=-0.183, p=0.002) B형간염에 대한 심각성을 많이 느낄수록 그리고 장애감을 적게 느낄수록 예방접종 이행이 많은 경향이 있었다. B형간염 예방접종에 영향을 미치는 요인을 분석한 결과 학년에 따라서는 2학년이 3학년에 비해 예방접종 이행이 0.39배(95% CI=0.21, 0.71) 낮은 것으로 나타났다. B형간염에 대한 심각성이 1단위 높아질수록 예방접종 이행률은 1.80배(95% CI=1.29, 2.52) 증가하였으며 장애감은 1단위 높아질수록 0.61배(95% CI=0.41, 0.90) 감소하는 것으로 나타났다(p<0.05). 따라서 치위생과 학생들이 의무적으로 B형간염 예방접종을 실천하기 위해서는 1학년 때부터 교육할 수 있는 교육과정 안에 프로그램 개발이 시급하다 할 수 있으며 구체적인 교육이 필요할 것으로 생각된다. 또한 일회성 교육이 아닌 지속적인 교육으로 학년별로 매회 교육해야 할 것이며, 정확하고 철저한 교육이 되어 의무적인 B형간염 예방접종이 이루어 질 수 있도록 구체적인 방안이 모색되어야 할 것으로 생각된다.

B형 간염 예방접종 전후 연령별 B형 간염 표면항체 양성률을 분석하기 위하여 제주지역 종합병원 검사의학과에 B형 간염 표면항체 검사가 의뢰된 13,855명의 혈청 검체를 대상으로 CMIA법으로 조사하였다. HBs Ab 양성률은 5,176건으로 37.36%이었으며, 성별에 따른 양성률은 여자가 40.13%로 남자의 34.77%보다 높게 나타났다. HBs Ab 측정 평균값이 가장 높은 연령군은 40대(399.86 mIU/mL)이었으며, 가장 낮은 연령군은 90대(211.50 mIU/mL)로 나타났다. HBs Ab 양성률이 가장 높은 연령군은 30대이며, 10대의 양성률이 가장 낮은 분포를 보인 것은 주목할 만하다. 10대~20대의 B형 간염 표면항체 양성률이 현저히 감소하는 경향을 보였으며, 특히 15, 18, 19세가 통계적으로 유의하였다. 이에 예방접종의 역가의 측정을 고려하고 추가접종 시기를 명확히 해야 한다고 사료된다.

Coronavirus disease 2019 (COVID-19) vaccination may non-specifically alter the host immune system. This study aimed to evaluate the effect of COVID-19 vaccination on hepatitis B surface Ag (HBsAg) titer and host immunity in chronic hepatitis B (CHB) patients. Consecutive 2,797 CHB patients who had serial HBsAg measurements during antiviral treatment were included in this study. Changes in the HBsAg levels after COVID-19 vaccination were analyzed. The dynamics of NK cells following COVID-19 vaccination were also examined using serial blood samples collected prospectively from 25 healthy volunteers. Vaccinated CHB patients (n=2,329) had significantly lower HBsAg levels 1-30 days post-vaccination compared to baseline (median, -21.4 IU/ml from baseline), but the levels reverted to baseline by 91-180 days (median, -3.8 IU/ml). The velocity of the HBsAg decline was transiently accelerated within 30 days after vaccination (median velocity: -0.06, -0.39, and -0.04 log₁₀ IU/ml/year in pre-vaccination period, days 1-30, and days 31-90, respectively). In contrast, unvaccinated patients (n=468) had no change in HBsAg levels. Flow cytometric analysis showed that the frequency of NK cells expressing NKG2A, an NK inhibitory receptor, significantly decreased within 7 days after the first dose of COVID-19 vaccine (median, -13.1% from baseline; p<0.001). The decrease in the frequency of NKG2A⁺ NK cells was observed in the CD56^dimCD16⁺ NK cell population regardless of type of COVID-19 vaccine. COVID-19 vaccination leads to a rapid, transient decline in HBsAg titer and a decrease in the frequency of NKG2A⁺ NK cells.

Interferon (IFN) alpha has been the first line therapy of chronic hepatitis B in children, but HBeAg seroconversion occurred in 26% of treated children compared to 11% of controls in multinational randomized controlled study. Recently, lamivudine was shown to be a potent inhibitor of Hepatitis B virus (HBV) reproduction both in HBeAg positive and in HBeAg negative (the pre-core mutant form) chronic hepatitis in randomized studies worldwide. Lamivudine therapy led to considerable improvement in the seroconversion rate of HBeAg in children with chronic hepatitis B, though long-term therapy resulted in the expansion of lamivudine-resistant mutant viruses. Combination therapy with lamivudine plus alpha-IFN does not seem to improve HBe Ag seroconversion. Above all, the most effective way to prevent hepatitis B is universal HBV vaccination.

This study was carried out to find the influencing factors on the acceptance of vaccination of viral hepatitis type B. Two groups of students, 362 undergraduates of Korea University were surveyed for research. The compliant group was 156 students who were inoculated with viral hepatitis type B shot more than one time. The non-compliant group was 206 students who were not inoculated. The measures used for this study were Multidimensional Health Locus of Control Scales and the one developed by the researcher on the basis of literature review about Health Belief Model. The results of this stuby were as follows. The awareness on health of the compliant group was higher than that of the non-compliant group(t=0.39, P<0.05), And perceived barrier of the compliant group was lower than that of the non-compliant group(t=0.35, P<0.05). But the knowledge about the viral hepatitis type B of the compliant group was lower than that of the non-compliant group(t=2.49, P<0.05). There were no differences between two groups in the perceived susceptibility of the hepatitis and the perceived benifit of the hepatitis vaccination. There was no difference between two groups in terms of the Inner Health Locus of Control (HLOC) and Chance HLOC. On the other hand Powerful-Others HLOC of the compliant group was higher than that of the non-compliant group(t=3.67, P<0.05). 'Parent's advice' was found to be the major answer to the motive of being vaccinated in the compliant group. This explains that the most influencial factor in determining one's health behavior is the parent's opinion. Answers to the question of the reason of not being vaccinated were, 'did not want to bother' and 'did not care yet' in order. As a whole, except for the awareness on health and the perceived barrier of the hepatitis vaccination, this study result shows disagreement with the past investigations on the inter-relationship between one's health belief or Health Locus of Control and the health behavior. The author of this study believes this was due to the limitation in the survey group's particular homogenity.

Purpose: The purpose of this study was to investigate the knowledge and attitudes towards hepatitis B among paramedic students. Methods: A self-reported questionnaire was completed by 395 paramedic students in Daejeon and Chungnam from May 10 to June 10, 2016. The questionnaire consisted of general characteristics of the subjects (9 items), knowledge of hepatitis B (20 items), and attitudes towards hepatitis B (7 items). Data were analyzed by t test, ANOVA, post hoc Duncan test, and Pearson's correlation analysis using SPSS v. 23.0. Results: The knowledge of hepatitis B was 10.52(${\pm}5.18$) out of 20 points and was significantly correlated with grade, vaccination, or antibody-positive irerspective of education. The positive attitude toward hepatitis B was 3.15(${\pm}.43$) and there was a significant correlation with family history irrespective of education. There was a statistically positive correlation between the knowledge and attitudes towards hepatitis B (r=.104, p=.039). Conclusion: Precise knowledge delivery and full understanding of hepatitis B should be incorporated into the education of paramedic students. Active infection control by emergency medical technicians should be maintained by hepatitis B prevention practices.

Background: Acute alcoholic intoxication patients (AAIP) are a common public health problem. The aim of this study was to perform a comprehensive laboratory analysis for these patients to investigate the co-morbid medical problem. Methods: We retrospectively reviewed laboratory findings of AAIP who were transferred to the emergency department (ED) from January 2017 to June 2017. Results: A total of 160 male patients were enrolled. Sixteen patients (16/160, 10.0%) and three patients (3/160, 1.9%) had macrocytic anemia and microcytic anemia, respectively. A total of 33 patients (33/160, 20.6%) showed thrombocytopenia ($<150{\times}10^9/L$). Twelve patients (12/159, 7.5%) showed low serum albumin level (<3.5 g/dL). Three patients (3/160, 1.9%) had chronic kidney disease stages 3-4 based on estimated glomerular filtration rate. Six patients (6/27, 22.2%) had high hemoglobin A1c (HbA1c) level (>7.0%). Positive rates of hepatitis B surface antigen and antiHBs antibody (anti-HBs Ab) were 3.5% (5/141) and 49.0% (68/141), respectively. Conclusion: Patients with AAIP who were transferred to ED had various laboratory abnormalities (anemia, thrombocytopenia, high HbA1c). They had low positive rate of anti-HBs Ab. This might be a public health problem, suggesting the need of hepatitis B virus vaccination program for AAIP. Our data suggest the need of further nationwide studies.

The purpose of this was to evaluate the level of knowledge about Hepatitis B and AIDS among dental hygiene students at six dental hygiene educational programs in nationwide, compare the findings to those of Song's study. 1703 dental hygiene students surveyed by mail and answered a questionnaire, using the questionnaire used developed by DiClemente el al., on Hepatitis B vaccination, antibody production, experience of unintentional needle stick injuries, experience of surgical operation and blood transfusion, personal risk factors for HBV and HIV, management of HBV and HIV postexposure management et al. The data indicated that dental hygiene students (79.0%) in this study had more HIV vaccination than dental hygiene(74.3%) in Song's study. As for recognition of antibody production after Hepatitis B vaccination, only 34.6% of respondents answered they knew having antibody production and 95% of respondents knew not having antibody production. Over one-half of the respondents (55%) answered they didn't even recognize having antibody production. 52.3 percent of dental hygiene students experienced unintentional needle stick injuries. The findings on the knowledge about Hepatitis B and AIDS were that dental hygienists (76.5 points) received higher mean score than those of dental hygiene students (71.0 points) and that the distribution of right answer rate also showed wider range in dental hygiene students (27.7~97.5%) than those of dental hygienist (41.2~99.5%). There were no statistical differences among dental hygiene education programs. Finding of this study support that the curriculum of dental hygiene program should include instruction on sources and methods of transmission of infectious diseases, risk of virus transmission in the workplace and principles of infection control. Furthermore, infection-control practices should be utilized routinely and their application to dental personnel, management of HBV and HIV postexposure management. Furthermore, for preventing the further spread of infectious diseases (HBV, HIV and AIDS${\cdots}$) caused by bloodborne viruses, imposing an obligation rather than recommendation on Hepatitis B vaccination to all dental personnel and routinely utilizing infection-control guidelines for all dental patients in dental practices (include dental educational programs) should be accomplished by coordination the government agency.

Objectives The purpose of this study is to report the clinical effects of oriental medical treatment on Extensive limb swelling which is rare adverse reaction of vaccination. Methods A 11 months old infant who appealed unilateral thigh swelling after immunization and signs of local inflammation was administered a complex herbal medicine consisting of five decoctions; Gwakhyangjunggisan, Binsosan, Danggwisusan, Samchulgunbitang and Gwibitang. The length of the constant regions of the thigh circumference was measured every visit. Each process was recorded by photograph. After one year from the first visit, phone call was conducted to follow-up. Results The length of the thigh after administration of herbal medicine did not change much, but the part where swelled hard became little bit softer. A year later, patient's growth and walking was normal but the swollen part not changed. Since then the similar adverse effects did not recur on booster doses vaccines. Conclusions The adverse reactions of vaccination are rarely reported and there is no specific treatment for swelling from Hepatitis B vaccine. It will be more helpful to study if more cases reported about any adverse drug reactions or any side effects from the immunization.
