Syntropy

from Wikipedia, the free encyclopedia

Syntropie (from ancient Greek συν syn , German , each other, together ' and τρέπειν trepein , German , rotate, turn' ) designated in the medicine originally the co-occurrence of two different diseases , favoring appear to each other in the same patient.

The term was first used in 1921 by Meinhard von Pfaundler and Luise von Seht . The opposite of syntropy they called dystropy .

Pfaundler and von Seht also developed a syntropy index, with the help of which the statistical probability of a combination of two ailments was given. H.-J. In an essay in 1965, Lange compiled the problems with which such an approach is afflicted and came to the conclusion that "usable syntropy studies are difficult, but not impossible". Lange specifically pointed out the problem of bogus associations that came to be known as Berkson's Fallacy .

In the meantime, the term syntropy is also used for the common occurrence of different diseases in the same patient, without a theory of statistics hiding behind the use of the word.

In the case of a positive syntropy, two diseases occur simultaneously or in immediate succession, while in a negative syntropy this is particularly rare, cf. Carlos Thomas, Infectious Diseases Atlas.
