ABSTRACT
The paper analyzes the etiology of diphyllobothriasis pathogens and their distribution in the world. It estimates the infection rate of the population with tapeworms, the value of different fish species and procedures for their cooking as factors for transmission of Diphyllobothrium to the population and the risk for infection with tapeworms through infected foods. Epidemiological surveillance measures in different (synanthropic and natural) foci of diphyllobothriasis and with various types of pathogens are considered.

The authors have analyzed the data available in the literature and statistical offices and the results of their observations of the epidemiological situation of leishmaniasis in the Russian Federation (RF). In October 1991 to December 2014, the RF registered 89, leishmaniasis cases, including 83 imported cases from 24 countries and 6 local cases. Out of the 83 imported cases, there were those diagnosed with anthroponotic cutaneous leishmaniasis (n=31), zoonotic cutaneous leishmaniasis (n=20), visceral leishmaniasis (n=31), and mucocutaneous leishmaniasis (n=1). The Republic of Dagestan and Eastern Crimea are visceral Ieishmaniasis-enderpic, areas. The obtained data on the local cases of visceral leisimaniasis in Dagestan and on its sporadic cases in Crimea suggest that it is necessary to conduct epidemiological, epizootological, and entomological surveys in the above areas and to develop a system for visceral leishmaniasis epidemiological surveillance encompassing the whole package of antiepidemic measures. The effective treatment of leishmaniases requires that the RF Ministry of Health should register some current antileishmanial drugs (such as Glucantime) as soon as possible.

The paper gives the results of treatment with micronized albendazole (Gelmodol-BM, World Medicine, UK) in 87 patients of the Department of Medical Parasitology and Tropical Diseases, Clinical and Diagnostic Center, Clinical Center, I.M.Sechenov First Moscow State Medical University. Thirty-two patients with echinococcosis 8 with alveococcosis (including 4 inoperable patients), 10 with ascariasis, 10 with toxocariasis, 15 with enterobiasis, and 12 people diagnosed with larva migrans were treated in 2013-2014. The drug's routine doses and dosage regimens were used. Albendazole (Gelmodol, World Medicine, UK) showed a high efficacy with good tolerability, which is highly competitive with that of the drugs manufactured by IPCA Laboratories Ltd., India (such as nemozole). Both medicaments above-mentioned may be successfully used in the treatment of many helminthisms.

The paper describes a case of acute opisthorchiasis in a 31-year-old female patient after ingestion of dried fish of the family Cyprinidae caught in the Oka River basin on the border of the Moscow and Ryazan Regions. This case could convince of that there was a risk of human Opisthorchis infection despite the zoonotic pattern of circulation of the pathogen in European Russia. The dietary intake of unsterilized fish of the family Cyprinidae caught in the Moscow and neighboring regions may give rise to Opisthorchis invasion and, it a large infectious dose, to acute opisthorchiasis.

51 patients with liver alveococcosis were operated on: radical operations with the whole hydatid tumor removal, cytoreductive operations with 50-80% of the tumor removal and alveococcal nodes' preserving on vital organs; and palliative manipulations, aimed the relief of complications were performed. According to the treatment results, the radical liver resection proved to be the most effective. When the complete tumor removal is impossible, cytoreductive operations are possible. Combination with antiparasitic therapy is required.

The paper gives the results of observations of 1558 patients before and after tourist travels to tropical countries and 368 individuals visiting the north areas of the Russian Federation. Different conditions (malaria, amebiasis, leishmaniasis, intestinal and tissue helminthiasis, insect bites, venomous fish pricks, medusa burn, tick bites, etc.) were found in 402 persons. Prophylactic immunization included vaccination against hepatitis A and B viruses, meningitis, typhus, yellow fever, tick-borne encephalitis in more than 2500 patients (not including influenza vaccination in the epidemic season). The performed observations reinforce the statement that imported pathology is urgent to Russia and suggest that it is necessary to develop this section of medicine and to set up a network of health care facilities with a necessary therapeutic and diagnostic base to render skilled care to tourists. It is essential to improve medical staff training in travel medicine.

A morphological group ofwhipworm (Trichuris trichiura) eggs, which is detectable in the soil samples from the city's different control lands, shows that their origin is heterogeneous and it is possible to differentiate them by morphometric signs. At the same time is necessary to consider the specific biological factors contributing to soil contamination. Priority in parasitic soil contamination should be given to animals, dogs in particular, which is supported by the fact that the dog walking grounds exhibit the highest contamination rates.

Whether the Russian praziquantel analog azinox can be widely used in the foci of opisthorchiasis was first assessed. The outpatient treatment of 7405 patients with the agent in doses of 30, 40, 60 mg/kg body weight revealed that azinox tolerance did not depend upon the intensity and degree of clinical infection signs but it was slightly worse when a dose of 60 mg/kg was given. Children virtually showed no adverse reactions, in adults their frequency was no more than 52 +/- 1.4%. The parasitological efficiency of azinox in the used doses was 96-99% in children and 82-86% in adults. There was a clinical improvement in 65% of the treated. Thus, the national drug azinox is not inferior to the imported agent bilthricide in tolerance, parasitological and clinical efficiency. Bearing in mind the equal efficiency, but the better tolerance and less cost of the drug doses of 30 and 40 mg/kg body weight, it is advisable to use them in the foci for outpatient treatment.

The results of wide uses of praziquantel (bilthricide, Bayer, Merck) to treat 2,440 persons in the outpatient setting of the endemic foci of opisthorchiasis in Tomsk Province suggest that the agent is highly effective (on the average of 97%) and well tolerable. There are no great differences in the efficiency of treatment, the frequency and magnitude of adverse reactions during out- and inpatient treatments. There are no either basic differences in the efficacy of praziquantel doses of 30, 40, and 60 mg used in the treatment of patients with Opisthorchis infection in whom 1 to 1.00 eggs per g feces are found. The use of praziquantel in a daily dose of 30 or 40 mg/kg in the outpatient setting permits the mass drug therapy of the population in the endemic foci, by reducing expenses on treatment. It is advisable to continue investigations of praziquantel used in small doses among the populations at low infection risk.
