KEY WORDS prenatal diagnosis, antenatal diagnosis,non-invasive, ultrasonography, osteogenesis imperfecta INTRODUCTION Many couples who have an increased genetic risk of having a child with osteogenesis imperfecta (01) Osteogenesis imperfecta is still not completely understood, and while there have been advances in diagnosing the disease, treatment is still limited.Prenatal ultrasonography is used to detect severely affected fetuses at about 16 weeks of pregnancy. Key Words: Prenatal Diagnosis, Skeletal dysplasias, Osteogenesis imperfecta.No any other malformations were observed on pre-natal ultrasonography. At 25th week, sonography also showed multiple fractures on bony structures including ribs. The prenatal sonographic findings in three of the osteogenesis imperfecta cases mimicked campomelic dwarfism, whereas the case of campomelic dwarfism was antenatally diagnosed as osteogenesis imperfecta.

Because osteogenesis imperfecta (OI) can manifest itself in a wide variety of ways, differential diagnoses are best categorized into the following three stages of life: Prenatal/neonatal.

Case Report: A prenatal diagnosis of lethal OI was made by ultrasonography at 18 weeks of gestation and therapeutic abortion was indicated.Osteogenesis imperfecta (OI) is a heterogeneous group of diseases affecting type I collagen and characterized by bone fragility.

Osteogenesis imperfecta (OI) is a group of genetic diseases in which the bones are formed improperly, making them fragile and prone to breaking.Ultrasound is the least invasive procedure for prenatal diagnosis and carries the least risk. Osteognesis Imperfecta Diagnstico y Manifestaciones.En ocasiones es posible realizar un diagnstico prenatal de OI mediante ecografa perinatal, que permite detectar posibles fracturas e incurvaturas de los miembros alrededor de la 16 semana de gestacin.

Osteogenesis Imperfecta (OI) commonly know as brittle bone syndrome. Osteogenesis Imperfecta is an inherited condition.Prenatal diagnosis, in the second trimester, by ultrasound in the most severe forms. Routine scanning shows shortness and deformity of limbs and abnormal skull shape. Between 1982 and 1986, osteogenesis imperfecta was diagnosed by ultrasound in seven fetuses. The known heterogeneity of osteogenesis imperfecta was confirmed by the prenatal ultrasonographic findings.

Osteogenesis Imperfecta. Mesenchymal Stem Cells as Donor Cells in OI. Prenatal Transplantation.We also summarize the two patients with OI who have received pre- and postnatal transplantation of MSC. Osteogenesis Imperfecta (OI), also known as Brittle Bone Disease, is a genetic disorder resulting in fragility of bones.There is a wide range of severity in those suffering from OI which may be lethal in the prenatal period, crippling postnatal or barely detectable which also result in varying life spans. So, osteogenesis imperfecta is a spectrum of different diseases but they all have one thing in common, severe bone fragility.The way we make the diagnosis is by DNA mutation analysis and prenatal diagnosis through amniocentesis is absolutely possible. Osteogenesis imperfecta (OI) is a genetic disorder characterized by bones that break easily, often from little or no apparent cause.genetics and the possibility of recurrence, and they can assist in prenatal diagnosis for those who wish to exercise that option.

Keywords: Osteogenesis imperfecta, prenatal diagnosis.In our case osteogenesis imperfecta Type II is pre-diagnosed with short narrow thorax, lack of ossification in cranium, severe micromelia and fractures and pregnancy is ended because of the presence of findings determining fatal prognosis. Abstract. A 21 yearold woman with progressively deforming or type III osteogenesis imperfecta (OI) presented for prenatal counselling and diagnosis at 10 weeks gestation. Family history was noncontributory. Osteogenesis imperfecta (OI) is a genetic disorder in which bones break easily. Sometimes the bones break for no known reason. OI can also cause weak muscles, brittle teeth, a curved spine, and hearing loss. Symptoms. Osteogenesis imperfecta (OI) can range from mild to severe. Most people with OI have fragile bones, and about 50 to 65 have hearing loss.A doctors evaluation. Sometimes analysis of cells or genetic testing. Prenatal ultrasonography.
