Takayasu’s arteritis is a chronic granulomatous arteritis with predominant involvement of the aorta and its main branches. It occurs both in youth and childhood, manifests between the ages of 10 and 30 years, female patients predominate. This article presents a clinical case of Takayasu’s arteritis in a child with prolonged fever. Clinical case. A 10-year-old girl E. was hospitalized with complaints of febrile fever episodes during the last two months; weakness and back pain were also noted. Observed by an endocrinologist since 2015 with a diagnosis of Stunted growth. Delayed physical development. Diffuse changes of the thyroid gland, euthyroidism. Since 2020 has been observed with the diagnosis Constitutional immaturity. A tendency toward constipation was noted. Observed by an allergist with atopic dermatitis, food and respiratory allergies were diagnosed. By the time of hospitalization, the girl had been ill for two months. During this period, four episodes of fever with scanty catarrhal manifestations were recorded. The diagnostic search went in different directions, infectious, systemic and oncological diseases were excluded. The echographic pattern was typical and highly specific for Takayasu’s arteritis. Additional examination also revealed changes in the celiac trunk in the form of narrowing of its lumen. Clinical diagnosis «Non-specific aortoarteritis, type III, acute phase, stenotic variant, grade 1–3 activity with lesions of the right and left common carotid arteries and the celiac trunk» was made as a result of clinical, laboratory and instrumental examination. This clinical observation demonstrates the difficulty in making a diagnosis due to the variety of clinical forms and the absence of specific disease markers. It takes on average a year and a half from disease debut to clinical diagnosis of the patient. However, lack of therapy over a long period can be crucial for an adverse outcome of the disease.

Windbreaks as an important part of agrobiocenoses detain snow on the inter-band space which causes the accumulation of pollutants in the soil including heavy metals (HM). The article presents the results of studies for 2001.2008 in the Republic of Mordovia on study the effect of windbreaks on the distribution of highly toxic HM in the layers of chernozem leached heavy loam (in the layers 0-20 cm, 30-40 cm, 50-60 cm) under conditions of windbreak and the protected field on the windy side. Age of deciduous trees is more than 50 years. Sampling points: windbreak, 10, 30, 50, 100, 150 and 250 m (background) from the strip. The soil contamination of the forest stripe with TM is more than in the field and indicates its ability to filter technogenic emissions. In the 0-20 cm layer of the windbreak the content of TM is 1.09 - 5.07 times higher than in the plowland of the geochemical area where the field is located; only Cu is less than the estimated permissible concentrations of HM. Therefore it is dangerous to collect mushrooms in forest belts around cities. The total content of HM varied in the soil layers of the field up to 60 cm. The redistribution of the maxima of the relative proportions of the HM content in the layers at a different distance from the strip depending on the metal was noted: 50 m for Pb, Zn, Cu, Co; in 250 m - more differentiated for Zn, Ni, Co. The content of HM in the soil of the background site is significantly lower than in the soil of the band across all layers for Pb, Zn, Ni; in the 0-20 cm layer for Cu; in the layers 0-20 and 30-40 cm - for Co. It is recommended to grow raw materials for dietary products and baby food in the center of the fields. The eluvial-accumulative coefficient shows the aerial and hydrogenic types of soil contamination associated with the distribution and quality of the snow cover in the field protected by the strip.
