From an historical point of view it has been interesting to study published opinions of authorities on obstetrics concerning the question of so-called medical complications encountered in their specialty. In the first edition of DeLee's Obstetrics1 (1913) "glycosuria" is considered as an entity, and the prognosis of diabetes (50 per cent mortality) is discussed without reference to any collateral features such as the simple one of proper treatment of diabetes. The fifth edition2 (1928) states that "today with proper treatment mortality is much lower, and in most cases pregnancy may be carried through to term." Proper treatment naturally means treatment by men trained in the field of metabolism.
The earlier pessimistic statistics regarding the outlook for the pregnant woman with heart disease or diabetes are almost completely lacking in what might be called comparative control. The gloomy prognoses are based almost entirely on comparisons of pregnant ill women
