Purpose: Hepatitis E outbreaks are a serious public health concern in the world. The pilots or air traffic controllers can be incapacitated by severe hepatitis symptoms. If the symptoms of acute hepatitis do not improve, it is not suitable for aviation duties.In this study, we compare of incidence status of hepatitis E virus (HEV) infections, and epidemic aspects between South Korea (from here on, ‘Korea’) and Japan. Methods: The raw data on confirmed of HEV infection cases were obtained from the National Notified Disease Surveillance System of Korea Diseases Control and Prevention Agency, the Ministry of Health and Welfare in Korea, and the National Epidemiological surveillance of Infectious Diseases surveillance system, administered by the National Institute of Infectious Diseases in Japan. Statistically significant differences between the epidemiological aspects and risk factors were determined using the Pearson’s chi-squared test or paired t-test. All data analyses were performed in Microsoft Excel 2010 (Microsoft, Redmond, WA, USA). Results: There were 191 cases of HEV infected cases with a prevalence rate (PR) of 0.37 per 100,000 populations of Korea in 2020. During the same year in Japan, there were 454 cases with a PR of 0.36. When compared, there is statistically none significantly differences. Moreover, both PR per 100,000 populations of HEV infections in habitat of two countries were compared, in the provinces (0.39) of Korea were much higher than that in capital city of Seoul (0.27; P<0.01), but that in Japan were capital city of Tokyo (0.84) was higher than that of the provinces (0.30; P<0.01). Male to female morbidity ratio was 1.65 and 3.78 in Korea and Japan, respectively. The distribution by the age adjusted groups were similar in Korea and Japan that the total cases occurred in the over 40-years-old age bracket, clearly showing a higher incidence in the elderly. Conclusion We believed that the HEV are a zoonotic virus, and human occurs mainly through the fecal contamination of water and consumption of contaminated meat from infected animals. In addition, HEV infection can be a problem for pilots and air traffic controllers as well, requiring further investigation and research.

Purpose: Zika virus (ZIKV) infection is a mosquito-borne Flavivirus disease. we investigated the epidemiological aspects and status of imported ZIKV infection cases in Korea (Republic of) and Japan during 2016–2020. Methods: Raw data of ZIKV infection cases from the Korea Diseases Control and Prevention Agency, and the National Institute of infectious Diseases in Japan, 2016– 2020. Results: There were 33 cases of ZIKV infection in Korea and 21 cases in Japan between 2016 and 2020. Cumulative incidence rate per 1,000,000 overseas travelers (OTs) of Korea (0.30) did not substantially differ that of Japan (0.27), respectively.We observed the ZIKV infected cases of male (69.7% of total cases) were much more than that for female (30.3%) in OTs of Korea (P<0.05). However, while there was none significant differences level between males (52.4%) and females (47.6%) in OTs of Japan. On the other hands, the distribution by adjusted-age groups for ZIKV infections were similar between Korean and Japanese that total cases occurred in the over 20 to 59-years old age, clearly more showing a higher infected of ZIKV (P<0.01). The presumptive origin imported ZIKV infection cases in Korean were as follows; Southeast Asia (81.8% of total cases) and Central & South Americas (18.2%), and those in Japan, these were Southeast Asia (42.9%) and Central & South Americas (42.9%) and Oceania (4.7%), respectively. Conclusion This study demonstrates that there is a similar pattern of imported ZIKV disease cases in Korea and Japan. Therefore, to prevent ZIKV infections, greater attention should be paid to individuals who are planning to travel to the presumptive regions of ZIKV.

A Case of double pylorus, in 56 year old man, was diagnosed by fiberoptic gastroscopy and upper gastrointestinal series. Two ovoid large openings of pyloric canal divided by smooth thickened septum were observed endoscopically And the relevant literatures on tihe subject were reviewed.

Purpose: The purpose of this paper is to study the epidemiologic series of Tsutsugamushi disease (TD), also known as scrub typhus in the Republic of Korea (Korea) and Japan. Methods: We investigated raw data of TD outbreaks from the National Notifiable Disease Surveillance System of the Korea Diseases Control and Prevention Agency in Korea, and the National Institute of Infectious Diseases in Japan, 2016 to 2020. Results: There were 36,785 cases of TD with a cumulative infectious rate (CIR) of 14.3 per 100,000 populations in Korea from 2016 to 2020. During the same period in Japan, there were 2,350 cases with a CIR of 0.4. When compared, Korea was much higher than that in Japan (P<0.01). In Korea, more females (60.2% of total cases) were infected than males (39.8%), while there was a significant difference between males (58.8%) and females (41.2%) in Japan, respectively (P<0.01). Conclusion These differences in TD risk factors reflect differences of vectors/hosts, climate, and geographical and cultural characteristics between the two countries. The surveillance of TD, primarily a zoonotic disease, should be continued in order to obtain a better understanding of its current status. Moreover, guidelines for the prevention of TD, and its control measures should be more established.

Purpose: Melioidosis is a zoonosis that can infect humans or animals. The disease is caused by the bacteria Burkholderia pseudomallei, which is found in contaminated soil and water. We investigated the epidemiological aspects of melioidosis cases among oversea travelers in Korea and Japan during 2011 to 2020. Methods: Raw data were obtained from the website of melioidosis cases from the Korea Diseases Control and Prevention Agency, and the National Institute of infectiousDiseases in Japan, 2011−2020. Results: There were 26 cases of melioidosis cases in Korea and 14 cases in Japan between 2011 and 2020. Cumulative incidence rate per 1,000,000 oversea travelers (OTs) of Korea (0.14) did not substantially differ that of Japan (0.09), respectively.The incidence of melioidosis in males (96.2% of total 26 cases) was much more common than in females (3.8%) in OTs of Korea (P<0.01), while there were significant differences level between males (85.7% of total 14 cases) and females (14.3%) in OTs of Japan (P<0.01). On the other hand, the distribution by adjusted-age groups for melioidosis cases were statistically similar distribution between Korean and Japanese that total cases occurred in the over 40-years old age, clearly showing a more infected of melioidosis (P<0.05). Conclusion This study demonstrates that there is a similar pattern of imported melioidosis cases in Korea and Japan. Therefore, to prevent melioidosis infections, greater attention should be paid to individuals who are planning to travel to the presumptive regions of melioidosis.

Patients tend to return to normal pronunciation patterns after fitting new dentures. However, for some patients, it takes a long time to adapt the new complete denture. In this case, the patient came to the hospital at the address of wanting to remake dentures due to wear and tear. After diagnosis through clinical and radiological examination, the maxillary complete denture and mandibular removable partial denture were remade. The patient complained whistling /s/ sound at the first check-up after placement of the new denture. The anterior palatal area of polished surface of the new maxillary complete denture was concave comparing to old denture, and this was the cause of the whistling /s/ sound. A tissue conditioning material was applied to the maxillary complete denture and patient made /s/ sound. The tissue conditioning material was replaced with self-curing type denture base resin, and the patient was immediately satisfied with clear /s/ sound. As an objective assessment, palatogram and speech analytics software was applied. In this case, a patient who received denture treatment complaining of difficulty in pronunciation underwent immediate denture repair, which resulted in patient satisfaction and improved pronunciation through objective evaluation.

The paraumbilical vein is one of the anastomotic channels between the portal and systemic circulatory systems, and rupture of the intra-abdominal varix is an unusual complication of portal hypertension that can lead to life-threatening hemoperitoneum. We experienced a case of hemoperitoneum due to a ruptured paraumbilical vein revealed by ultrasonography (US), computed tomography (CT) and percutaneous transhepatic portography. The last mentioned demonstrated a dilated paraumbilical ve i n draining two branches of the left portal vein into the right external iliac vein, and we performed coil embolization at the site at which the presumed site of paraumbilical vein was presumed to cause hemoperitoneum. We describe this unusual case of hemoperitoneum due to a ruptured paraumbilical vein in a known liver cirrhosis patient in whom portal hypertension was treated by means of coil embolization.
