To study the 20-years' clinical alteration and alcoholism basing on the changes in its clinical symptoms and course.
The study included 527 alcoholics with formed alcohol withdrawal syndrome: 181 alcoholics were examined in 1988-1990 (Group 1) and 346 alcoholics in 2011-2012 (Group 2).
In Group 1, vodka consumption dominated at all stages of alcoholism. Group 2 included 172 alcoholics with the domination of vodka consumption and 174 alcoholics with mixed consumption. It was shown that in comparison with Group 1 (1988-1990 patients) patients from Group 2 (2011-2012) had slower and mild development of alcoholism, especially those in the mixed consumption group. The authors suggest that the change of the clinical pattern in Group 2 was due to the change in the composition of consumed alcoholic beverages.

Increased prevalence of dental caries evidently is correlated with increasing intake of sugar and carbohydrate-rich foods. Preceding and accompanying this dietary alteration might have been a shift from a hunting-and-gathering subsistence strategy to one based on agriculture. We corroborated this conjecture by means of a study on the prevalence of caries, antemortem tooth loss (AMTL) and tooth wear among 16th to 19th century hunter-gatherers and agriculturalists who co-existed in West Siberia.
Indigenous skeletons (n?=?75) exhumed from Tatar, Selkup, Khant, and Nenet graves along with Russian settler skeletons (n?=?79) from Izyuk were examined. The prevalence of caries, AMTL and tooth wear among the indigenous peoples were compared with those among the Russian settlers. The resulting statistical inferences were tested using package R.
The agriculturalist Russian settlers showed a significantly higher prevalence of dental caries (11.88%) than did the non-agriculturalist indigenous Siberian people (3.85%). Among the latter, the prevalence was the lowest in the Khanty and the highest in the Tatars, suggesting that caries differently affected each sub-group of indigenous Siberian people. Correspondingly to the case of dental caries, the Russian settlers' AMTL prevalence also was higher than that of the indigenous Siberians, regardless of age. On the other hand, the native Siberians and the Russian settlers did not show statistical differences in tooth wear.
In the study on 16th to 19th century West Siberian populations, we were able to corroborate our presumption that agriculturalists ingesting a carbohydrate-rich diet would have higher rates of dental caries and AMTL than would hunter-gatherers.
The emergence of novel avian influenza viruses in migratory birds is of concern because of the potential for virus dissemination during fall migration. We report the identification of novel highly pathogenic avian influenza viruses of subtype H5N8, clade 126.96.36.199, and their reassortment with other avian influenza viruses in waterfowl and shorebirds of Siberia.
The article presents the analysis of elicited and systematized indices of morbidity of acutely contagious diseases in the Empire of Russia and the USSR in 1887-1949. The firmly established in scientific literature opinion about stable epidemic well-being set in the USSR in 1930-1940s is disproved. It is established that in the USSR during this period occurred increasing of morbidity of infectious diseases. The main causes of this occurrence are demonstrated.
