BACKGROUND: Recent predictions of catastrophic epidemic surge of HIV infection in East Asia concern experts and governmental organizations. As in many other areas, countries in East Asia show diversities in their HIV epidemics, both geographically and temporally. However, they have similar regional, cultural and racial characteristics which allow them to have certain common factors. Having a clear picture of the current extent and feature of HIV/AIDS in this region is a very difficult task largely due to the fast pacing of expending epidemic and difficulty in data-sharing among countries in the region. Hence, we decided to study the epidemiologic feature of HIV/AIDS in East Asia through East Asia Network on HIV (EAN-HIV). MATERIALS AND METHODS: The epidemiological patterns of HIV/AIDS in East Asian countries were investigated by collecting data through EAN-HIV. RESULTS: The HIV/AIDS epidemic in East Asia started relatively late at mid 1980s. Since then, the number of newly infected HIV/AIDS cases has been steadily increasing with stiffer escalation in recent years. In China and Taiwan, IDU plays an important part in the swiftly growing HIV epidemics; however, in other regions like Korea, Japan, and Hong Kong, MSM (men who have sex with men) seems to be more of a problem. The major subtypes of HIV in East Asia are subtype B, C, and CRF01_AE, and rapidly evolving circulating recombinant forms (CRF) between subtypes such as CRF07_BC give dynamic change to the current status. CONCLUSION: The incidence of HIV/AIDS is rapidly increasing in East Asia. The epidemic pattern has undergone dynamic changes over time. China seems to be the leading source of HIV/AIDS epidemic in East Asia due to its large population and rapidly growing epidemics.

Clonorchis sinensis infection is one of the most common parasitic infections that is widely distributed in Southern Korea as well as China, Japan, Taiwan, Hong kong, and Vietnam and countries in Eastern Asia. The disease is caused by the ingestion of infected raw or under- processed freshwater fish. The clinical manifestations depend on the number of flukes in a patient, the period of infestation, and the complications. We experienced a 10-year-old boy who had a history of ingestion of raw fresh-water Chinese mitten crab preserved in soy sauce and presented with chronic urticaria. The causal organism, Clonorchis sinensis, was found by the identification of parasite ova in stool. We report a rare case of chronic urticaria related to Clonorchis sinensis that was successfully treated with praziquantel and review the pertinent literature.

This current study's goal is to summarize the literature regarding Antenatal Depression (AD) in the East Asian countries of Taiwan, China (including Hong Kong and Macau), Japan, and Korea. The main search utilized a Pub med Chinese Electronic Periodical Service (CEPS) literature review using keywords 'AD', and 'Prenatal Depression' with searches for 'Japan', 'Korea', 'Taiwan', 'Hong Kong' and Macau'. The rates of AD in East Asia appear to be relatively close to those in the Western literature, although certain studies showed slightly decreased rates. Many of the risk factors for AD were the same in the Eastern and Western literature. These risk factors included demographic factors such as younger age, smoking, low education and income, and unemployment. Other risk factors were physical symptoms such as menstrual pains and nausea. Finally, psychological factors such as a poor response to the pregnancy, poor spousal support, and poor family support were associated with AD. With regard to treatment, there were no studies examining the administration of psychotropic medications for AD. The literature from East Asia both confirmed many Western findings and made unique contributions to the literature on AD. The treatment of AD in East Asia appears to be an entity which, despite its morbidity, has not been adequately studied.

The REAP-AP study recruited 3,746 patients with schizophrenia, in March and April 2016, from 71 centers in 15 Asian countries/territories namely Bangladesh, China, Hong Kong, India, Indonesia, Japan, Korea, Malaysia, Myanmar, Pakistan, Singapore, Sri Lanka, Taiwan, Thailand and Vietnam. Our findings reveal a trend according to which high dose antipsychotic prescription is more prevalent in Eastern Asia (especially, Japan and Korea) than in other regions of Asia. This historical factor may be associated with our finding of an Eastern Asian preponderance of high dose antipsychotic prescription.

Hepatolithiasis is rare in western countries, but is fairly common in East Asia, including Japan, China, and Taiwan. Calcium bilirubinate stones account for the majority of intrahepatic calculi, while intrahepatic cholesterol stones are very rare, the incidence being 0.37% of all gallstones. However, several investigators have recently reported an increased incidences of cholesterol gallstones in hepatolithiasis cases and have discussed the differing mechanisms for their formation in the intrahepatic biliary tree of patients with calcium bilirubinate stones and cholesterol stones. We report two cases of intrahepatic cholesterol stone, with emphasis on the radiologic findings, and review the literature.

North Korea is located on the northern part of the Korean Peninsula in East Asia. While tick-borne pathogens of medical and veterinary importance have been reported from China and South Korea, they have not been reported from North Korea. To screen for zoonotic tick-borne pathogens in North Korea, ticks were collected from domestic goats. A total of 292 (27 nymph, 26 male, 239 female) Haemaphysalis (H.) longicornis were collected and assayed individually for selected tick-borne pathogens. A total of 77 (26.4%) were positive for Anaplasma bovis, followed by Bartonella (B.) grahamii (15, 5.1%), Anaplasma phagocytophilum (12, 4.1%), Bartonella henselae (10, 3.4%), and Borrelia spp. (3, 1.0%) based on 16S ribosomal RNA and ITS species-specific nested polymerase chain reaction. Using the groEL-based nested PCR, a total of 6 and 1 H. longicornis were positive for B. grahamii and B. henselae, respectively. All products were sequenced and demonstrated 100% identity and homology with previously reported sequences from other countries in GenBank. This is the first report of the detection of tick-borne pathogens in the North Korea and suggests that farm animals may act as reservoirs for zoonotic tick-borne pathogens.

The species of the genus Chlorociboria Seaver are very common on the forest floor, and can be easily distinguished by small and numerous blue-green fruitbody, especially the blue substrate dyed with xylindein produced by this group. This genus has rather high species diversity in the Southern Hemisphere, while a little attention was paid to this group in East Asia area. During a field survey in South Korea, several Chlorociboria specimens were collected. Based on morphological and phylogenetic analyses, three species of Chlorociboria were reported, including one new record in South Korea and one new record in Jeju Island. The key to the species of Chlorociboria from South Korea is provided.

In East Asia during the second half of the 19th century, overseas mission work by Protestant churches thrived. Missionaries built schools and hospitals and effectively used them for evangelism. In the 20th century when Social Gospel Movement was expanding, medical work has been recognized as a significant mission service in and by itself. This article reviewed the construction and characteristics of missions work conducted by Canadian Presbytery; missionary doctors and Korean doctors who worked at the mission hospitals; why the missionary medical work had to stop; and career paths taken by Korean doctors upon liberation from Japanese occupation. The Canadian Presbytery missionaries, unlike other denomination missionaries, were rather critical of Imperial Japan, but supportive towards Koreans. This could have stemmed from the reflection of their own experience of once a colony of British Empire and also their value system that promotes egalitarian, democratic and progressive theology. The Sung-jin and Ham-heung Mission Bases were a community, interacting organically as a 'Triangle of Church, School and Hospital.' The missionaries mobilized the graduates from Christian schools and organized a Young Men's Christian Association (YMCA). Some of the graduates were trained to become medical doctors or assistants and worked at mission hospitals. Missionary doctors' approaches to balancing evangelism and medical practice varied. For example, Robert Grieson went through confusion and struggled to balance conflicting roles as a pastor for evangelism and also as a physician. Kate McMillan, on the other hand, had less burden for evangelism than Grieson, and focused on medical work by taking advantage of the opportunity that, as a woman, she can easily approach Korean women. Still another case was Florence Murray who practised evangelism within the hospital setting, and successfully carried out the role as a hospital administrator, going beyond 'women's work' as McMillan did. Korean doctors and assistants who worked at the mission hospitals had seen the spread of Protestantism in their youth; had received modern education; had experienced the fall of own country in 1910 and nationwide protest against Japan in 1919. The majority of them were graduates of Severance Medical College, the hub of missionary medicine at the time. After the resignation from the mission hospitals, 80 percent of them became self-employed general practitioners. The operations of the mission hospitals began to contract in 1930 due to tightened control by Imperial Japan. Shrine worship imposed on Christians caused internal conflict and division among missionaries and brought about changes in the form and contents of the mission organization. The incidence of the assault of Dr. Grieson brought about the dissolution of Sung-jin mission base and the interruption of the operation of Je-dong Hospital. As the Pacific War expanded, missionaries were driven out of Korea and returned home. In conclusion, the missions work by Canadian Presbytery missionaries had greatly impacted Protestantism in Korea. The characteristics of Canadian Presbytery were manifested in their support of Korean nationalism movement, openness for Social Gospel, and maintaining equal footing with Korean Christians. Specifically we note the influence of these characteristics in Chosun doctors who had worked in the mission hospitals. They operated their own hospitals or clinics in a manner similar to the mission hospitals by providing treatment for poor patients free of charge or for a nominal fee and treating the patients in a kind and humanistic way. After the 1945 Liberation, Korean doctors'career paths split into two directions. most of them defected to South Korea and chose the path to work as general practitioners. A few of them remained in North Korea and became educator of new doctors. It is meaningful that former doctors of Canadian missionary hosptal became dean of 2 medical colleges among 3 of all in early North Korea. This article does not cover the comparative analysis of the medical work by the missionaries of Canadian Presbytery and other denominations. It is desirable to include this analysis of the contents and the comparison in a future study of Korean doctors who participated in the mission hospitals, by denomination and by geographical region.
