One of the burning issues of the day in modern obstetrics is the issue of the prevention of postpartum diseases, giving a clinical complex of symptoms, known as childbirth fever. This disease everywhere carries away a mass of victims to the grave, and, moreover, in the most flourishing period of life, especially here in Russia, where rational medical care does not exist everywhere. Therefore, I think it is not superfluous to touch on this topic and report the data that I was able to derive while observing the rich material of the Leopold clinic, where I am a Volontairarztom. Doctor Jacob Rosenblatt.
