Results for: amniocentésis
Esta animación corta ilustra y explica el procedimiento de amniocentésis durante el embarazo de la mujer. Este procedimiento ayuda a determinar la salud del feto durante su desarrollo en el vientre de la madre. Durante este procedimiento se usan las imágenes obtenidas por el sistema de ultrasonido para visualizar un punto seguro en el abdomen donde introducir una aguja hasta penetrar el útero y entrar al saco amniótico para extraer una muestra del fluido amniótico sin afectar el feto.
FETAL NUCLEIC ACID TECHNOLOGY OFFERS POTENTIAL ALTERNATIVE TO AMNIOCENTESIS
Research studies demonstrating the viability of an approach to routinely detect the presence of fetal DNA in a mother's blood to accurately diagnose or rule out genetic defects -- as early as the first trimester -- was presented at the 27th Annual Meeting of the Society for Maternal-Fetal Medicine being held in San Francisco. This future diagnostic technology, currently under development at Sequenom, Inc. (Nasdaq: SQNM), shows promise that a universal alternative to such invasive genetic screening procedures as amniocentesis and chorionic villus sampling, may be available in the future.
These implications are important to women with high-risk pregnancies, in that this future non-invasive screening technique will have significant benefit to all expectant mothers, especially on the heels of new guidelines endorsed by the American College of Obstetricians and Gynecologists (ACOG) that call for risk assessment of all pregnancies for fetal chromosomal abnormalities.
Through technology licensing agreements with clinical laboratories, Sequenom expects a non-invasive application of its technology for fetal Rhesus D (RhD) typing to become available in these laboratories beginning in the first half of 2007. Rhesus disease can occur when the blood of the expectant mother is incompatible with her unborn child.

Scientists in Cyprus, say they’re close to full development of a new test for Down syndrome in the womb -- and medical professionals are calling it a game changer.
The new procedure analyzes a pregnant mother’s blood for differences between her DNA and the DNA of her fetus. Down syndrome results from an extra copy of chromosome 21, and is a common cause of mental retardation. (Video: WTXF)
Currently, the only way to diagnose Down syndrome before birth is through a process called amniocentesis. Though most women forgo that test. A writer for Technorati explains why.
“Tested at 15-16 weeks gestation, a needle is inserted into the mother’s uterus and amniotic fluid is extracted. As a result, 1 in 100 pregnancies will end in miscarriage.”
On Philadelphia Fox affiliate WTXF, one doctor can barely conceal his excitement.
Dr. MIKE CIRIGLIANO: “A blood test! Is that cool? That is really cool.”
Anchor: “That is amazing.”
Dr. MIKE CIRIGLIANO: “Having gone through this again with my own wife -- Do you want to have an amniocentesis? There are risks associated, but you want to know.”
Dr. MIKE CIRIGLIANO: “And so, this could be a sea change.”
But a writer for Care2 reports 90 to 95 percent of women terminate their pregnancies after a Down syndrome diagnosis, so while the new test is exciting -- it also raises some high-stakes ethical questions.
“The parents of disabled children tend to say ... their love for their child has far outweighed the difficulties. At the same time, however, making sure that children with Down's Syndrome ... have a positive, supported life does require a significant commitment on the part of the parents, both emotional and financial.”
Finally, a doctor from Boston’s Children’s Hospital is optimistic about the issue -- hoping potential parents are aware of growing societal support for people with Down syndrome and their families.
Dr. BRIAN SKOTKO: “What I also envision is a world where people with Down syndrome continue to prove that they can succeed and they’re important contributors to their local communities. I think the challenge is, how do you convey these new possibilities into the prenatal discussions that are coming around the corner so that mothers and fathers can make an informed decision?”
The researchers behind the study say they aren’t ready to roll out the test just yet, but hope to have it on the market within one to two years.
