Placental pathology in relation to the White's classification of diabetes mellitus.
The objective of this study was to investigate various macroscopic and microscopic features of the placenta in pregnancies complicated by diabetes according to White's classification. A total of 148 placentas were studied. Sixty-five were from control patients and 83 from diabetic mothers. The diabetic mothers were further divided into three groups according to White's classification. There were 40 cases in White's group A and 36 cases in White's group B. There were 7 cases in White's groups C and D combined. Advanced maternal age and grandmultiparity were significantly higher in White A, White B and White C&D compared to the normal group. Mean weight of the mother was higher in White group A and group B compared to the control group and group C&D. The placental weight and neonatal weight were increased provided the diabetes was not complicated by vascular disease. With accompanying vascular disease the placental weight and neonatal weight were reduced compared to the controls. As a result of increased perinatal jeopardy the rate of operative delivery was higher in diabetic mothers. No major difference was observed in microscopic changes of placentas in different groups according to White's classification and the normal group.
