Objective:
We examined factors associated with the development of spontaneous intertwin membrane separation in dichorionic twin pregnancy.
Methods:
Medical charts of 618 dichorionic twin pregnancies without the history of amniocentesis managed after 22 weeks' gestation at Japanese Red Cross Katsushika Maternity Hospital between 2002 and 2017 were reviewed.
Results:
Twenty-four cases (3.9%) were diagnosed with spontaneous intertwine membrane separation. The presence of different fetal sex and separated placentae were associated with the development of spontaneous intertwin membrane separation in dichorionic twin pregnancy (different fetal sex: crude odds ratio 2.44, 95% confidence interval, 1.1-5.5, p = .03; separated placentae: crude odds ratio 4.14, 95% confidence interval, 1.3-13, p = .01).
Conclusion:
The development of spontaneous intertwin membrane separation in dichorionic twin pregnancies seemed to be associated with dizygotic.

The transcription elongation is regulated via pausing of RNA polymerase on several occasions during transcription. In bacteria, these halts are necessary because the transcription of DNA into mRNA is coupled to the translation of that mRNA...
