Objective To explore the genetic polymorphism of Y chromosome D-M174 haplogroup and sub-haplogroups in East Asia. Methods The samples of 1 426 unrelated male individuals from East Asia were collected, and then 7 Y chromosome haplogroup D-M174 and the Y-SNP of its sub-haplogroups were detected with mini-sequencing. The 22 Y-STR genotypes were detected with DNA Typer™ Y26 kit. The haplogroup was analyzed using direct counting method, heatmap, phylogenetic cluster and network graph cluster, and then distribution of genetic polymorphism and the clustering relation between populations and samples of Y chromosome D haplogroup were discussed. Results Haplogroup D-M174 were distributed mostly among Tibetans （40.96%）and Japanese （35.71%）, while less or none were distributed among the surrounding areas of Tibet and other areas. Conclusion The geographical distribution of Y chromosome D-M174 haplogroup in East Asian populations has significant characteristics.

The incidence of tuberculoma of the brain in different countries varies reatly. They form a high percentage of intracrnial lesions dealt with in countries of Asia, Eastern Europe, Italy, Spain and South America. The recent introduction of the potent antituberculosis remedies, far from diminishing the incidence of tuberculoma of the brain, is more likely to increase it. This case was a 18 year old male who had increased intracranial pressure signs and characteristic signs which was suggestive lesion in posterior fossa. Conray ventriculography revealed nearly total obstruction of distal portion of aqueduct of Sylvius with displacement to the right side. Intensive antituberclous treatment then was started after removal of tuberculoma in cerebellar vermis and then discharged with fully recovery. References were reviewed as will.

The number of people living with HIV/AIDS continues to grow, estimated to be 39.5 million as of the end of 2006, while 4.3 million people were newly infected in 2006. The proportions of women has continued to grow, currently approaching 50%. Sub-Saharan Africa continues to bear the brunt of global epidemic, comprising 63% of all infections worldwide. The most striking increases have occurred in East Asia, Eastern Europe, and Central Asia. High-risk behaviors (intravenous drug use and unprotected sex between men or with paid sex workers) are the predominant route of transmission. The number of people with HIV/AIDS continues to increase since the first report of HIV in Korea, now approaching 4,580 as of the end of 2006. The real magnitude of HIV epidemic is believed to be much larger than the recent estimates by UNAIDS shows (13,000 people with HIV infection). The prevalence among the general population is still low (less than 0.1%; probably 0.003~0.01%). The HIV epidemic in Korea shows several peculiar features: 1) a male predominance suggesting that the epidemic may still be largely confined to male homosexual community, while the transmission through heterosexual contact remains less prominent, 2) a conspicuous absence of contribution of intravenous drug use to current epidemic, and 3) a very small number of vertical transmission due to the relatively limited number of infected women. The HIV epidemic is expected to continue to grow in the foreseeable future in Korea as well as globally unless drastic efforts are made to cope with the epidemic.

Prostate cancer (PCa) risk calculators (RCs) with prostate-specific antigen (PSA) and other risk factors can greatly improve the accurate prediction of potential risk of PCa compared to PSA. The European Randomized Study of Screening for PCa Risk Calculator (ERSPC-RC) and the Prostate Cancer Prevention Trial Risk Calculator (PCPT-RC) are developed on the Western population. However, the Western RCs showed limited diagnostic efficacy in the Eastern Asian population, mainly due to racial differences between the two populations. We aimed to review the application of Western RCs and Eastern Asian RCs in Eastern Asian cohorts and to identify the characteristics and efficacy of these RCs.

BACKGROUND: Travel-related risks for infectious diseases vary depending on travel patterns such as purpose, destination, and duration. In this study, we describe the patterns of travel and prescription of vaccines as well as malaria prophylaxis medication (MPM) at a travel clinic in South Korea to identify the gaps to fill for the optimization of pre-travel consultation. MATERIALS AND METHODS: A cohort of travel clinic visitors in 2011 was constructed and early one-third of the visitors of each month were reviewed. During the study period, 10,009 visited the travel clinic and a retrospective chart review was performed for 3,332 cases for analysis of travel patterns and prescriptions. RESULTS: People receiving yellow fever vaccine (YFV) (n = 2,933) were traveling more frequently for business and tourism and less frequently for providing non-medical service or research/education compared to the 399 people who did not receive the YFV. Overall, most people were traveling to Eastern Africa, South America, and Western Africa, while South-Eastern Asia was the most common destination for the non-YFV group. Besides YFV, the typhoid vaccine was the most commonly prescribed (54.2%), while hepatitis A presented the highest coverage (74.7%) considering the natural immunity, prior and current vaccination history. Additionally, 402 (82.5%) individuals received a prescription for MPM among the 487 individuals travelling to areas with high-risk of malaria infection. Age over 55 was independently associated with receiving MPM prescription, while purpose of providing service and travel duration over 10 days were associated with no MPM prescription, despite travelling to high-risk areas. CONCLUSION: Eastern Africa and South America were common travel destinations among the visitors to a travel clinic for YFV, and most of them were travelling for tourism and business. For the individuals who are traveling to areas with high-risk for malaria, more proactive approach might be required in case of younger age travelers, longer duration, and travel purpose of providing service to minimize the risk of malaria infection.

Inonotus obliquus is a fungus that causes white heart rot on several broad-leaved species. This fungus forms typical charcoal-black, sterile conks (chaga) or cinder conks on infected stems of the birche (Betula spp). The dark brown pulp of the sterile conk is formed by a pure mycelial mass of fungus. Chaga are a folk remedy in Russia, reflecting the circumboreal distribution of I. obliquus in boreal forest ecosystems on Betula spp. and in meridional mountain forests on beech (Fagus spp.) in Russia, Scandinavia, Central Europe, and Eastern Europe. Distribution at lower latitudes in Western and Southern Europe, Northern America, Asia, Japan, and Korea is rare. Infected trees grow for many years without several symptoms of decline. The infection can penetrate through stem injuries with exterior sterile conks developing later. In the Czech Republic, cinder conk is found on birches inhabiting peat bogs and in mountain areas with a colder and more humid climate, although it is widespread in other broad leaved species over the Czech Republic. The most common hosts are B. pendula, B. pubescens, B. carpatica, and F. sylvatica. Less frequent hosts include Acer campestre, Acer pseudoplatanus, Alnus glutinosa, Alnus incana, Fraxinus excelsior, Quercus cerris, Q. petraea, Q. robur, Q. delachampii, and Ulmus sp.
