Background: In recent years, there has been a lot of research on the relationship between dentists and patients on the factors that cause the patient to follow a treatment and be loyal to his dentist. Objective: The purpose of this review is to study the literature related to communication in the dental practice. Data collection: The articles reported in this literature review were searched on the PubMed database. Outcomes: According to some authors, 65% of the information is transmitted by means of non-verbal methods and only 35%-verbally. In this respect, the following have been described: models of behavior dentist-patient; Harter's steps sequence of patients' involvement in the health care decision-making process; Sahm's, Bartsch's and Witt's research on the importance of communication, according to which the information properly received by the patient is related to the satisfaction of the treatment. Some assessment tools for the psychological state before and during the treatment have been described-scale Corah, Gale and Illig-(DAS) for measurement of the anxiety from dental treatment; (DFS)-measures the level of fear of treatment; Janke' study with its own developed and standardized questionnaires-(STAIDFS); Corah's tool for assessing the cognitive, emotional and behavioral satisfaction of patients-(DVSS). Conclusion: The conclusion to be drawn is that dentists should be trained and in their work should apply adequate communication methods, tailored to the individual characteristics of each patient, to build confidence between each other.

Chronic heart failure is one of the most dreadful complications in the early postoperative period following lung transplantation. At the same time, the effect of using levosimendan in the early post-lung transplant period is currently insignificant and remains debatable. This paper presents a clinical case where levosimendan was successfully used in a patient with right ventricular heart failure during lung transplantation undergoing central venoarterial extracorporeal membrane oxygenation (VA-ECMO).

The novel SARS-CoV-2 coronavirus, which originated in December 2019 in Wuhan, China, has triggered an outbreak of a respiratory illness called COVID-19. Helium is a colorless inert gas, odorless and tasteless. Thermal helium-oxygen therapy is a new and innovative method that allows you to maintain the diffusion capacity of the lungs. The clinical case presented in this article shows that inhalation of a thermal gas mixture of helium and oxygen (t-He/O2) in the standard therapy of a patient with pneumonia caused by SARS-CoV-2 positively influenced the clinical picture of the disease, improves gas exchange, and promotes accelerating the elimination of the virus, rehabilitation and discharge of the patient.

The implementation of organ transplantation programs in our country is far from perfect. Many regions do not have transplantation centers, in many regions the work on organ donation is not carried out. Intensification of this vital work is of key importance – the need for organ transplantation remains unfulfilled in many regions of the Russian Federation by 70–90 %. The activity on organ donation must be realized with strict administrative control and administrative stimulation. It does not represent the sphere of interests of particular transplantologists. It is a strategically important task, the implementation of which should be carried out at the state level. The key importance in the implementation of organ transplantation program is the hospital where the potential donor is located, identified and accompanied. In the literature and daily practice the outdated term “donor base” is often used, the use of which we consider unacceptable. The donor hospital is a spring, a source of life, the work in which has a key, starting character.

The moral and ethical aspects of organ donation for transplantation constitute a new section of the doctor's activity. The correct and motivated awareness of the answers to the main questions that may arise from members of the public, patients, members of their families, medical personnel, undoubtedly, is within the competence of the doctor. This work is devoted to the analysis of existing approaches to answering the main questions arising around the activity of preserving the organs of the deceased for transplantation. The work was done in the format of a catechism, questions and the answers offered to them. Answers are given as one of the options.
