[Pre-eclampsia versus essential hypertension--the course of pregnancy, labor and fetal outcome].

By means of an exact nephrologic examination 6 weeks post partum of 128 patients with hypertension in pregnancy an exact classification in preeclampsia (46 per cent), chronic hypertension (34%) and superimposed preeclampsia (13 per cent) is possible. In cases of essential hypertension a hypotensive therapy is necessary.

[Value of prostaglandins in a pre-eclampsia-equivalent animal model].

Pregnancy-induced hypertension is no uniform disease with one cause and one pathophysiologic course. On the contrary it seems to be a multifactorial event with a very different symptomatology and a variable damage of various organs. Because of the heterogeneity of the disease and the difficulty of differentiation these various kinds of courses clinical studies, mostly retrospectively done, have to be criticized.
