Abstract
Acknowledgement
First, and foremost, I feel always indebted to GOD, the most kind
and the most merciful.
I am also greatly indebted to Prof Dr. Ibrahim El-Mitwally Samaha,
Professor of Obstetrics and Gynaecology, Faculty of Medicine, Ain
Shams University, for his valuable help, great interest and continuous
encouragement throughout the progress of this work.
I am also greatly indebted to Dr. Ahmed Ismail Abou-Gabal, Assist.
Professor of Obstetrics and Gynaecology, Faculty of Medicine, Ain
Shams University, for his meticulous supervision, great interest, and
generous help throughout the progress of this work.
Finally I like to record that the pain of converting blank paper to a written
thesis at home was made bearable by the kind support and understanding
of my family.
