title: Osteogenesis imperfecta in pregnancy: two case reports and review of literature.
abstract: Osteogenesis imperfecta (OI) is an inherited disease where basic pathology is of defective maturation of collagen. It is more common in women, and the incidence in pregnancy is 1 in 25,000 to 30,000. A multidisciplinary approach is necessary. Ideally, genetic counseling is sought before conception. Once pregnant, prenatal diagnosis can be established by chorion villous sampling. Serial scans would identify the affected fetus with fractures. A cesarean delivery is advocated if the fetus is affected or if the mother has pelvic fractures. An experienced anesthetist should be involved. Because these women are more likely to have a postpartum hemorrhage due to uterine atony, Syntocinon infusion and close observation in the third stage is indicated.
