On chronic azotemic nephritis without hypertension

Not so long ago, before our eyes, one might say, like a Deus ex machina, a slender, beautiful and seemingly solidly built in all its parts, the teachings of Volhard and Fahr grew up. But nothing is eternal under the moon, especially in medicine, where, as Wagner wrote, teachings are born only to disappear in five years, and so, in this thoroughly built building, mainly in its foundations, indeed, over time individual bricks began to fall out, and it began to loosen little by little. And the closer one looks into this doctrine and checks it against the practical side of the question and the life of the clinic, the more and more one becomes convinced that the whimsical life, even in its ordinary reveals-diseases, often does not want to fit into the Procrustean bed of schemes and hits us with surprises where everything seemed already finished, legalized, immutable, undeniable and established.
