Doctors of the Moscow Institute of Emergency Children's Surgery & Traumatology led by famous children’s doctor Leonid Roshal have expressed condolences to the relatives and friends of Elizaveta Glinka, known as Dr. Liza, who saved many lives of children during the armed conflicts.

Elizaveta Glinka was a kind and responsive person and was slight of figure. Her life is an exploit. A dignified person, and a person who saved children has died. All children really loved her," the institute’s press service said.
