Conversations with the Experts- Dr. Ronald Wapner

For our Conversations with the Experts series, Dr. Ronald Wapner, MD, professor of Maternal Fetal Medicine at Columbia University, sat down to discuss genetic screening in Obstetrics. Dr. Wapner is an internationally known physician and researcher in the field of reproductive genetics, and helped to pioneer the development of chorionic villus sampling (CVS) and multi-fetal reduction. He has led studies into the accuracy, efficacy and clinical advantages of prenatal diagnosis using micro-array analysis, helping lead the way to new non-invasive screening tests for pregnant women.
Importantly, Dr. Wapner discusses how doctors must help patients understand what the new genetic screening tests mean, counsel them, and make sure they understand that any such test should be followed by invasive testing, such as CVS or Amniocentesis, to make a firm diagnosis. It’s extremely important to understand confounding factors of age, weight, residual risk, and the like involved in the new genetic screenings, in order to make sure the patient fully understands the information and can make a truly informed decision.

Conversations with the Experts- Dr. Alfred Abuhamad

Dr. Alfred Abuhamad, MD was kind enough to speak with us about the use of 3d Ultrasound, after an excellent lecture on patient safety in obstetrics that will be available through our regular audio podcast feed. Dr. Abuhamad talks about the advantages of 3d ultrasound in clarifying diagnosis, and its potential to help reduce unnecessary procedures.

GYN Ultrasound- Retained Products of Conception

In our third video in the GYN Ultrasound series, Dr. James Manley, Dr. Vrunda Patel and Dr. Samata Mcclure discuss diagnosis and treatment of retained products of conception.

The placenta acts as an interface between the maternal and fetal blood supplies, and due to this infiltration, on occasion, some parts of this tissue do not fully separate from the uterus after birth, miscarriage or termination of pregnancy.  This retained tissue can cause heavy bleeding, pain, fever, and uterine tenderness.  Ultrasound can be a useful tool is helping to diagnosis retained products of conception and developing an appropriate treatment plan.


GYN Ultrasound- Ovarian Torsion

In the second video in our GYN Ultrasound series, Dr. James Manley, Dr. Megan Wasson and Dr. Andrew Ward discuss ovarian torsion.

Ultrasound can be used to help diagnosis and treat ovarian torsion, also referred to as adnexal torsion.

Occasionally, the ovary can “twist”, causing a patient significant pain, while compromising the blood flow to the ovary and fallopian tube.  A quick diagnosis and treatment is important to be able to treat and save these structures from damage secondary to vascular compromise.

GYN Ultrasound Video Series – The Normal Ovary

We’re adding video lectures to our audio podcasts here at OB GYN To Go.  The first series will be a number of videos discussing aspects of GYN Ultrasound.

The first lecture in this series features Dr. James Manley, along with Dr. Kelly Ruhstaller and Dr. Audrey Merriam discussing the normal ovary.  Because the ovary changes in appearance due to hormonal fluctuations, it’s important for residents to recognize normal versus pathological findings to avoid over diagnosis and treatment of patients.

Please let us know what you think of our new video lectures by dropping us an email at, or leaving a comment here.

Meet The Experts Series- Dr. Peter Von Dadelszen

We’re starting a new video series on OB GYN To Go, to supplement our audio lectures.  In our new Meet The Experts series, guest lecturers will be featured in short videos to talk about how they became interested in their area, and how their research has evolved over time.

We’re very excited to present this first Meet The Expert interview featuring Dr. Peter Von Dadelszen, Professor of OB GYN and Senior Research Scientist at the University of British Columbia.  Dr. Von Dadelszen is the world’s leading expert on the diagnosis and treatment of pre-eclampsia, and he is actively working on ways to diagnosis and treat preeclampsia in the developing world, where 99% of women in low and middle income countries die from pre-eclampsia.

We will also include audio of Dr. Von Dadelszen’s grand rounds lecture and the more informal session with OB GYN Residents on the audio feed of OB GYN To Go.
