Obstetrician and Gynecologist in Chief to the University of Michigan Hospital. Lea Bros. & Co., Phil. and New York. 1907. Chapter XIX._ Pephritis. From statistics we find that even excluding the cases of eclampsia, the maternal mortality from nephritis during pregnancy is 33%, and the fetal mortality between 50% and 60%. P. 352. Women suffering from a chronic nephritis should be advised strongly against marriage, especially in the presence of a cardiac or pulmonary lesion. Married women should be warned against impregnation. P. 354. Pyelitis. “On account of the increased dangers of pyelitic and especially of a pyelonephritic process during pregnancy, women suffering from these diseases should be warned against marriage. Married women should be warned against a new impregnation, on account of the marked tendency of pyelitis to recur with every pregnancy.” P. 355. _PRACTICAL OBSTETRICS. Thos. Watts Eden.

Saunders Co. 1913._ All forms of nephritis have a very bad influence on the pregnancy, abortion and premature labor being common. (66% Hofmeier) Seitz found that only from 20% to 30% of the children survived. One of the causes of habitual death of the fetus, abortion, and premature labor is chronic nephritis. P. 497. “The children of nephritics are usually puny and pale.” P. 497. Both mother and child are seriously jeopardized by chronic nephritis, the mortalities being about 30% respectively. P. 497. Women with chronic nephritis should not marry, and if married, should not conceive. P. 498. Diabetes. Sterility is common. Abortion and premature labor occur in 33% of the pregnancies. The children, if the pregnancy goes to term, often die shortly after birth, the total mortality being 66%. P. 502.
