Re: Diabetes teratogenicity in mice is accompanied with distorted expression of TGF-β2 in the uterus. Fein et al. 2001;22:59–71. Response to H. Kalter.

Abstract

To the Editor: Dr. Kalter claims that our assertion "Early embryonic deaths as well as malformed newborns are among complications of the diabetic pregnancy" [1] is wrong, both if it refers to humans or animals. While respecting Dr. Kalter's opinion that, neither experimental nor epidemiological studies prove the teratogenicity of maternal diabetes, we cannot agree.
