Photophoresis of topical steroids in the treatment of severe forms of lichen ruber planus of oral mucosa

The objective of the study is to search for new methods of treatment for lichen ruber planus with high efficacy, few complications and side effects, as well as providing a long-term therapeutic effect. The authors used the method of photophoresis (red LED radiation + topical steroid) in the combination treatment of 40 patients with severe forms of lichen ruber planu

Carbon emission from Western Siberian inland waters

High-latitude regions play a key role in the carbon (C) cycle and climate system. An important question is the degree of mobilization and atmospheric release of vast soil C stocks, partly stored in permafrost, with amplified warming of these regions. A fraction of this C is exported to inland waters and emitted to the atmosphere, yet these losses are poorly constrained and seldom accounted for in assessments of high-latitude C balances. This is particularly relevant for Western Siberia, with its extensive peatland C stocks, which can be strongly sensitive to the ongoing changes in climate. Here we quantify C emission from inland waters, including the Ob' River (Arctic's largest watershed), across all permafrost zones of Western Siberia. We show that the inland water C emission is high (0.08-0.10 Pg C yr(-1)) and of major significance in the regional C cycle, largely exceeding (7-9 times) C export to the Arctic Ocean and reaching nearly half (35-50%) of the region's land C uptake. This important role of C emission from inland waters highlights the need for coupled land-water studies to understand the contemporary C cycle and its response to warming. Rivers and lakes are thought to be a major conduit of loss for the massive amounts of carbon locked away in high-latitude systems, but such losses are poorly constrained. Here the authors quantify carbon emissions from rivers and lakes across Western Siberia, finding that emissions are high and exceed carbon export to the Arctic Ocean

STANDARDIZATION OF METHODS OF CORROSION PROTECTION IN THE OIL REFINING COMPLEX

Nowadays, many industries suffer losses from the failure of technical products due to damage to products and materials resulting from corrosion. The cause of corrosion is not only exposure to the external environment, but it can also be early aging of the metal, bio-damage. As a result, modern equipment manufacturers are finding more and more technologically effective ways to combat corrosion. All methods of protection used must be regulated. Therefore, one of the most effective ways to solve the problems of protecting metals from corrosion is their comprehensive standardization. This paper will consider a set of standards used in the manufacture of equipment to protect it from corrosion and aging.В настоящее время многие предприятия несут потери из-за выхода из строя оборудования, возникающего в результате коррозии. Причиной коррозии является не только воздействие внешней среды, но и раннее старение металла, биоповреждения. Вследствие чего современные производители оборудования находят все более технологически эффективные способы борьбы с коррозией. Все используемые способы защиты должны быть регламентированы и нормированы. Поэтому, одним из эффективных путей решения вопросов защиты металлов от коррозии, является их комплексная стандартизация. В данной работе будет рассмотрен комплекс стандартов, применяемых в производстве оборудования для защиты его от коррозии и старения

Features of Medical Care Providing to Patients with Digestive Diseases in the Krasnodar Region during the COVID-19 Pandemic

The aim of the study: optimization the medical care provision to patients with diseases of the digestive system (DD) in the Krasnodar Region during the COVID-19 pandemic.Material and methods. The analysis of the features of the DD course in the Krasnodar Region was carried out according to the data of form C 51 “Distribution of the dead by sex, age groups and causes of death” of the Territorial Federal State Statistics Service in the Krasnodar Region, as well as monitoring the quality of medical care for patients with DD for the period from 2019 to 2021 years.Results. During the COVID-19 pandemic, the routing of gastroenterological patients, dispensary observation and preventive measures have undergone some changes. In the structure of total mortality in the Krasnodar Region, mortality from DD was 21.6 % in 2020 and 4.0 % in 2021. The decrease in the growth of mortality rate, including from DD, in the second year of the pandemic is associated with the completed healthcare systems reformatting. The increase in hospital mortality in patients with gastric and duodenal ulcers, ulcerative colitis, and diverticular disease had a significant impact on mortality rates from DD. The decreasing number of hospitalizations was explained due to the conversion of a number of hospitals into hospitals for the treatment of patients with COVID-19. The hospitalization was mainly carried out for emergency indications and patients with a more severe course of the disease. The pandemic has increased the need for telemedicine: 378 tele-consultations on the gastroenterological profile was carried out in the Krasnodar Region in 2021.Conclusion. Healthcare system workload in the Krasnodar Region increased significantly during the coronavirus pandemic that required a number of structural adjustments. In recent times, the regional health care is returning to the planned mode of providing medical care

Surgical treatment of portal hypertension complications in patients with liver cirrhosis

Objective: Improving the results of surgical treatment of portal hypertension complications in patients with liver cirrhosis.Material and methods: The results of medical care for 328 patients with liver cirrhosis, who were treated in the surgical departments of the central district and city hospitals of the Krasnodar Region, were analyzed. The effectiveness of minimally invasive surgical treatment of portal hypertension complications in 832 patients with liver cirrhosis treated at the Regional Clinical Hospital no. 2 of the Ministry of Health of the Krasnodar Region were also evaluated.Results: The mortality rate in patients with liver cirrhosis, admitted in first-level institutions of medical care due to acute bleeding from esophageal varices, reached 26.3%. In conditions of surgical treatment of complications of portal hypertension in a third-level institution of specialized care it did not exceed 4.7%.Conclusion: The optimal approach to the surgical treatment of patients with liver cirrhosis is to stop the bleeding from esophageal varices at the first stage of medical care and to treat portal hypertension complications using minimally invasive technologies in a multidisciplinary clinic involving a multidisciplinary team of doctors
