I would like to say words of gratitude and appreciation to all employees, especially Irina Alekseevna Li and Svetlana Mikhailovna Iskhakova, for their help in solving my question related to the organization and determination of survey tactics based on available documents. Yesterday there was a state of complete despair and helplessness. Thank you, Doctors, for competent, timely, prompt assistance! Health, strength and patience to all of you in your hard work! Thank you very much!
