[World Collections of Parasitic Worms].

This article provides information about the depositories of parasitic worms in the scientific institutes and museums in the United States, Japan, and Europe (the total number of samples and the availability of types of helminths from various classes), as well as information on the availability of electronic catalogues of the collections in the continental, national, and regional centers for collective use. The extent of this material has determined the necessity of creating digital collections and libraries that would represent a new form of storing, displaying, and exchanging information for scientific research. An analysis was performed of the current state of approaches and methods of development of the specialized information retrieval system (IRS) and databases (DBs) on the parasitic worms in Russia on the basis of a common conceptual data model, taking into account their local use (as desktop systems of database management) and access by scientists worldwide via the Internet.

[Treatment and rehabilitation of patients with chronic opisthorchiasis with skin manifestations].

Our studies demonstrated that chronic opisthorchosis with a skin syndrome is accompanied by a severer clinical course. The course of rehabilitation measures with the use of resort recreation (mud-bad cure) combined with traditional treatment stages makes it possible to considerably enhance the efficiency of treatment of both opisthorchosis and its skin manifestations, and should be applied more often in practice.

[Role of migration processes in oncologic epidemiology of Siberia and Far East].

The paper presents the analysis of the cancer death rates among the population of a Norilsk industrial area and compares the rate and structure among newcomers and natives. The persons who long live in this area more frequently die of cancer diseases than migrants. They have high mortality rates for most sites (the stomach, esophagus, bowel, liver, pancreas).
