Purpose: We performed to reveal the association between the Helicobacter pylori infection and body weight among children. Methods: Out retrospective study included patients who underwent the H. pylori immunoglobulin G testing at Konyang University Hospital between March 2011 and June 2014. These patients were classified as seropositive (28 boys, 27 girls; mean age: $9.89{\pm}3.28years$) or seronegative (55 boys, 54 girls; mean age: $9.84{\pm}3.02years$). Next, we compared various characteristics between the seropositive and negative groups, as well as between obese children (body weight ${\geq}90th$ percentile) and non-obese children (body weight <90th percentile). Furthermore, we compared the change in body weight after 2 months of treatment with amoxicillin, clarithromycin and omeprazole among the 55 seropositive children (14 treated children and 41 non-treated children). Results: There were no differences in the weights and laboratory data for the 55 seropositive children and 109 seronegative children (weight; $40.96{\pm}18.11kg$ vs. $36.85{\pm}13.72kg$, respectively; p=0.14). And, there was no difference in the prevalence of H. pylori infection among the 29 obese and 135 non-obese children (p=0.581). However, after 2 months of eradication, the 14 treated patients exhibited a significant weight gain ($+0.91{\pm}0.52kg$), compared to the 41 non-treated patients ($-0.29{\pm}1.16kg$, p=0.025). Conclusion: Our findings present that obesity was not associated with the H. pylori infection, although H. pylori eradication led to significant increase in body weight.

This study provides a comprehensive analysis of the epidemiological trends and challenges in managing tuberculosis (TB) in livestock in Korea from 2013 to 2022. Tuberculosis, caused by the Mycobacterium tuberculosis complex, is a significant zoonotic disease affecting cattle, deer, and other domesticated animals. Despite the initiation of a test-and-slaughter eradication policy in 1964, TB has continued to persist in Korean livestock, particularly in cattle and deer. This study used data from the Korea Animal Health Integrated System and provincial animal health laboratories to analyze TB incidence in various livestock including different cattle breeds and deer species. The results from 2013 to 2022 showed a peak in TB cases in 2019 with a subsequent decline by 2022. The study highlighted a significant incidence of TB in Korean native cattle and the need for amore inclusive approach towards TB testing and control in different cattle breeds. Additionally, the study underscored the importance of addressing TB in other animals such as goats, wildlife, and companion animals for a holistic approach to TB eradication in Korea. The findings suggest that while the test-and-slaughter strategy has been historically effective, there is a need for adaptation to the current challenges, and learning from successful eradiation stories on other countries like Australia. A collaborative effort involving an expanded surveillance system, active private sector participation, and robust government support essential for the efficient eradication of TB in livestock in Korea.

미국 등 선진국에서는 장례종사자들의 질병감염에 대한 위험성과 감염예방의 중요성이 심도있게 연구되어 이에 관련된 가이드라인이 제시되고 있으나, 국내에서는 이에 대한 연구가 미비하다. 국내에서 장례종사자의 건강관리는 장례업자나 종사자 개인의 노력에 전적으로 의존하기 때문에 매우 열악하며, 장례종사자의 감염에 대한 연구 및 역학 조사 등이 매우 필요하다고 판단된다. 본 연구에서는 선진국의 장례지도사 가이드라인을 참고하여 노출가능성이 높은 질병, 개인위생, 물질적 및 공간적 관리에 대한 한국형 장례종사자 감염관리 가이드라인 모형을 제시하여 장례식장내 효율적 감염관리 및 장례종사자의 감염예방을 이루고자 하였다.

Objectives : Many studies have shown that helicobacter pylori (H. pylori) infection is associated with gastroduodenal diseases. The purpose of this report was to evaluate recently published research on the influence of oriental herbal medicine on H. pylori infections. Methods : Recently published literature were systematically compared with their findings of how oriental herbal medical treatment affects H. pylori-associated disease. Results : The eradication rate of H. pylori in oriental herbal medicine groups was 66.93% while it was 66.02% in western medicine groups. In oriental herbal plus western medicine groups, interestingly, the rate increased to 84.78%. On the other hand, the total treatment efficacy rate of H. pylori in oriental herbal medicine groups was 91.27%. The treatment efficacy rate in oriental herbal plus western medicine groups rose to a record 93.22%, which was 15.34% higher than the rate in western medicine groups. In addition, the rate of adverse effects was 2.71%, 4.85%, 15.80% in oriental herbal medicine, western medicine, and oriental herbal plus western medicine groups, respectively. Diarrhea was most frequently observed in oriental herbal medicine groups, while nausea was most frequently observed in the other groups. Conclusions : The results of this study showed that herbal medicinal treatment can increase the rate of H. pylori eradication and improve H. pylori-related gastrointestinal symptoms. These findings suggest that herbal medicine can solve the problems including side effects due to antibiotic resistance of standard triple therapy.

Historically, Plasmodium vivax malaria has been one of the most highly endemic parasitic diseases in the Korean Peninsula. Until the 1970s, vivax malaria was rarely directly lethal and was controlled through the Korean Government Program administered by the National Malaria Eradication Service in association with the World Health Organization's Global Malaria Eradication Program. Vivax malaria has re-emerged in 1993 near the Demilitarized Zone between South and North Korea and has since become an endemic infectious disease that now poses a serious public health threat through local transmission in the Republic of Korea. This review presents major lessons learned from past and current malaria research, including epidemiological and biological characteristics of the re-emergent disease, and considers some interesting patterns of diversity. Among other features, this review highlights temporal changes in the genetic makeup of the parasitic population, patient demographic features, and spatial distribution of cases, which all provide insight into the factors contributing to local transmission. The data indicate that vivax malaria in Korea is not expanding exponentially. However, continued surveillance is needed to prevent future resurgence.

The current status and future prospects of parasitic infections in Korea is briefly reviewed. Soil-transmitted helminth infections including ascariasis, trichuriasis, and hookworm infections decreased remarkably. owing to the national control activities excuted by the Korea Association of Health Promotion(formerly Korea Association of parasite Eradication) using mass heath education. Important recent trends include reemergence of vivax malaria since 1993, persistence of food-borne trematode infections including clonorchiasis and intestinal trematode infections, increased detection of zoonotic parasitosis, close-up of infection with opportunistic parasites including cryptosporidiosis, toxoplasmosis, and pneumosytosis, increase of imported tropical infectious disease, appearance of new parasitic disease such as gymnophalloidiasis, and increase of accidental infections with free-living amoebae. These trends represent greatly changed overall patterns of parasitic infections in Korea.

During the last two decades, the rapid increase in aquaculture world wide, particularly in finfish and shellfish culture, is the result of both area expansion and production intensification. Under these conditions, the prevalence and spread of infectious diseases have increased as a result of higher infection pressure and decreased resistance of the aquatic animals. Accordingly, the effective control of infectious diseases has become more and more important to development of aquaculture. Recently the Pathology Team of National Fisheries Research and Development(NFRDI), has played pivotal roles in establishing the national management and control system of aquatic animal health and disease by new legislative works and technical guidelines. Under the national aquatic animal disease control framework, the Pathology Team of NFRDI and MOMAF(Ministry of Maritime Affairs and Fisheries) should also establish effective management and regulations, with the support of enforcement and monitoring policies. In conjunction with effective aquatic disease national management, financial assistance or alternative compensation options for aquaculture should also be available in the event of production losses or eradication system.

Recently, onset of bacterial disease, especially infiltration of chronic respiratory diseases have been increasing at high rate. The main cause of these diseases are originated from inappropriate sanitary management and slow progress in introducing system and herd free system, which are the base of productivity improvement in bigger pig management, Methods for the prevention and removal of these diseases, are divided into four categories. The first category includes prevention and removal of infectious diseases by organizing strict animal quarantine, enforcing vaccination, and legal regulation and disposal at the time of outbreak. The second category includes improvement of production systems. This purpose can be achieved by discontinuing the open herd system, which brings on the invasion of foreign pathogens and replacing the system by the closed type of farm. To Continue eradication process step-wisely by performing the all-in all-out system at every pig pen or herd level is also effective for this purpose. The third category includes introduction of herd free system can be achieved by repopulating conventional pigs with SPF pigs. If these means are unrealizable from economic or technical viewpoint, medicated early weaning system is perfomed. This system consists of disinfection of pigsty at pre-postpartum stage, application of drugs to pregnant sows and newborn piglets in accordance with the medication program, and early weaning and rearing of newborn piglets in isolation. The fourth category is sanital leading by veterinarians, aimed to eliminating incentives for diseases through diagnoses. Their main activities include periodical monitoring and improvement leading on each responsible subject.
