HISTORICAL ASPECTS OF THE VESICOURETERAL REFLUX STUDY AMONG CHILDREN

Vesicoureteral reflux is one of the most widely spread lower urinary tract diseases among children, which is the primary reason for the disturbed urodynamics and development of the chronic pyelonephritis. As a consequence, the contamination of the urinary tracts may be the reason for further development of the chronic kidney disease, renal hypertonia and may inevitably lead to disability. The modern diagnostics of the vesi coureteral reflux is very important for the adequate conservative and operative treatment. In the given article, the authors highlight the diagnostics development stages of this disease and provide comparative characteristics of different diagnostic methods.Key words: vesicoureteral reflux, urodynamics, diagnostics, children

The oldest volcanic glass in the early paleoproterozoic boninite-type lavas, Karelian craton: Results of instrumental investigations

Since Early Precambrian volcanic rocks are typically strongly altered by superimposed processes, they retain primary composition and texture only in exceptional cases. Such a case is observed in the Early Paleoproterozoic volcanic rocks of the Vetrenyi Belt Formation of the synonymous riftogenic structure in southeastern Karelia, where volcanic glass is locally preserved [1-3]. The Sm-Nd, Re-Os, and U-Pb (zircon) ages of volcanic rocks of this formation range from 2.5 Ga in the lower parts to 2.41 Ga in the upper parts of the sequence [1-3]. Zolotykh and Ladygin [4, 5] also confirmed the presence of volcanic glass in these rocks. During short-term field works in 2000, we collected additional samples in the southeastern termination of the graben-shaped Vetrenyi Belt, where the least altered rocks were preserved. The samples were mainly treated at the Institute of Geology of Ore Deposits, Petrography, Mineralogy, and Geochemistry

Как следствие, инфицирования мочевых путей могут явиться причиной развития в последующем хронической почечной недостаточности, ренальной гипертонии и неизбежно приводят к инвалидизации. Своевременная диагностика пузырно-мочеточникового рефлюкса имеет большое значение для проведения адекватного консервативного или оперативного лечения. В данной статье авторы знакомят с этапами развития диагностики этой болезни, дают сравнительную характеристику различных диагностических методов.
