HEMORRHAGIC FEVER WITH RENAL SYNDROME: AN ACUTE OCCUPATIONAL DISEASE OR AN OCCUPATIONAL ACCIDENT?

Posted in 2021, Issue №7 (109) July 2021, MEDICINE | 0 comments

The article presents an analysis of a clinical case associated with acute occupational kidney damage from the influence of a biological factor. The authors examine the relevance of the problem, the prevalence of hemorrhagic fever with renal syndrome in the Russian Federation and abroad, as well as the issue of diagnosis and examination of professional suitability in the case of kidney damage from a biological factor of occupational origin. It is shown that the frequency of occupational kidney damage of an infectious nature remains underestimated both due to the aspects of the clinical course and the impact of factors of the working environment, and on the part of expert medics and employers.

The study also discusses the following issue: should hemorrhagic fever with renal syndrome be considered an acute occupational disease or an accident at work if the disease developes as a result of performing work duties.

It is proposed to regard cases of hemorrhagic fever with renal syndrome not as an acute occupational disease, but as an occupational accident involving investigation and the processing of this type of investigations in accordance with the Labor Code of the Russian Federation.

CONTAMINATION OF VEGETABLE PRODUCTS WITH EGGS, HELMINTH LARVAE, AND CYSTS OF PATHOGENIC INTESTINAL PROTOZOA

Posted in 2021, Issue №7 (109) July 2021, MEDICINE | 0 comments

The article contains a study of 4792 food samples, 7776 studies were performed in total. The share of fruit and vegetable products was 62,3% (n=2984), of which 2.8% (n=84) did not meet the norm.

In most cases, the research received vegetable products – 85,7% (n=2559), represented by 23 species. The number of samples that do not meet sanitary and parasitological indicators equals 2,4% (n=62), of which the bulk (90,4% (n=56) of all contamination findings among vegetables) are dead Strongyloides stercoralis larvae, while 1,6% (n=1) include live Strongyloides stercoralis larvae, Toxocara canis eggs, Opisthorchis felineus, Entamoeba histolytica cysts, as well as mixed infestations fertilized eggs of Ascaris lumbricoides+dead larvae of Strongyloides stercoralis and unfertilized eggs of Ascaris lumbricoides +dead larvae of Strongyloides stercoralis.

Therefore, the eggs and larvae of helminths are more often found in samples of vegetable products that had direct contact with the ground; the presence of positive findings in vegetable samples indicates contamination of these products with the feces of infected animals (dead larvae of Strongyloides stercoralis and eggs of Toxocara canis) and humans (eggs of Opisthorchis felineus, Ascaris lumbricoides, Enterobius vermicularis and Entamoeba cysts histolytica); the presence of helminth eggs (eggs of Opisthorchis felineus, Ascaris lumbricoides and Enterobius vermicularis) and cysts of pathogenic intestinal protozoa (Entamoeba histolytica) indicates contamination of manure with feces of infected people.

MODERN DATA OF TRICHINELLOSIS OF THE KHABAROVSK REGION

Posted in 2021, Issue №7 (109) July 2021, VETERINARY SCIENCE | 0 comments

The article analyzes the infection with trichinosis in animals and the incidence of this parasite among residents of the Khabarovsk Territory over the past 5 years. The main source of human infection remains bear meat and wild boar meat. The frequency of infection of bear meat in recent years has varied from 0,5 to 4,45%. Although it previously reached a stable spread of trichinosis due to various environmental and social factors, including poaching. Cases of infection of people (including children) by means of meat of stray dogs are noted. In this regard, it is necessary to strengthen control over spontaneous markets and meat of captured wild animals and inform the population about the possibility of infection with trichinosis.

HEAVY METAL CONTENT IN THE SOILS OF THE KRYMSKY DISTRICT OF KRASNODAR KRAI

Posted in 2021, BIOLOGY, Issue №7 (109) July 2021 | 0 comments

The article presents the results of studying soils for zinc and lead content. An important problem of modern ecology is the contamination of soils with heavy metals, this fact determines the direction of this research. Natural compounds, precipitation, and fertilizers are the source of heavy metals in the landscape systems. The research was carried out in separate landscapes and in different zones of the Krymsky District of Krasnoyarsk Krai. In the soils of the district, the study found such heavy metals as zinc, lead, cadmium, cobalt, nickel, and copper in different amounts. They enter the body of animals and humans with plant food, water, and accumulate in the kidneys, liver, and other organs. The data obtained demonstrate that the content of heavy metals in the soils of different landscapes varies widely. The lead content in the soils of different zones of the region varies significantly. The highest concentrations of lead were found in the urban zone. The lowest content of the total form of zinc and its active form is typical for biogenic landscapes. The highest proportion of the active form of zinc is found to be in urban territories.
