RESUMEN
In this note we explain by an example what we understand by a balance situation and by a balance equation in terms of measures. The latter ones are an attempt to start modelling of (not only) diffusion-reaction or mass-conservation scenarios in terms of measures rather than by derivatives and other rates. By means of three examples this concept is extended to two-features (= two-traits-) balance situations, which, e.g., combine features like aging and physical motion in populations or physical motion and formation of polymers by means of a single model equation.

Placenta percreta in early pregnancy is rare and has been documented in only a few cases. We report on a patient with abdominal pain in week 10 of pregnancy. Sonography revealed a defective embryonic development and the absence of a border line between trophoblast and myometrium, as well as invasive growth in the region of isthmocervical transition, so curettage was performed. Heavy bleeding at this stage made a hysterectomy necessary. Histological examination revealed a placenta percreta. Because of possible complications, the therapy of choice for a placenta percreta is a hysterectomy, as was performed in this case.
