Dr. Chapa’s OBGYN Clinical Pearls

The only structure of fetal gastrointestinal tract (GIT) which is seen on routine second trimester anomaly scan is the fetal stomach. Under normal conditions, the fetal stomach "bubble" is seen on the left side of the fetal abdomen. This is a normal finding on an ultrasound and indicates the stomach's normal position. There are two functions of the fetal GIT: 1. Propulsive action by peristalsis which takes the swallowed amniotic fluid up to the small bowel; 2. Absorption – the amniotic fluid is absorbed through the fetal small bowel. When the stomach is found prenatally to be located on the right side, it is called dextrogastria. Today in our high-risk prenatal clinic, we encountered a patient whose fetus was found to have this rare condition dextrogastria. Is this an isolated issue? What does this mean for clinical outcomes.

This crucial discussion emphasizes the importance of understanding patient experiences and managing pain effectively to improve outcomes.

Just today in clinic, we had a patient, who was well into her third trimester, come to her regular scheduled appointment with new onset left-sided facial droop. Yeah, that’s concerning! A complete history and physical was performed and the diagnosis was made of Bell’s palsy. This is not a rare event and it can be extremely stressful for the affected mother to be because everybody knows facial droop is not normal! And we have recent data regarding this. In July 2025 in the Journal of Plastic, Reconstructive, and Aesthetic Surgery, authors confirmed that Bell’s palsy can have real negative functional and psychosocial implications for those affected. So, in this episode, we are going to discuss Bell’s palsy in pregnancy. How do we differentiate this from the more serious differential, which is a stroke? What about treatment?

Maternal concerns about decreased fetal movement can be alarming, affecting up to 15% of pregnancies. The podcast delves into why routine labor induction isn't recommended solely for this issue. The discussion highlights the cerebroplacental ratio (CPR) as a potential ultrasound tool for assessing fetal well-being and early placental insufficiency. The results of the CEPRA trial suggest the CPR could influence clinical practice, though caution is advised since routine induction may not improve outcomes. Practical guidance is emphasized throughout.

Brain-type natriuretic peptide (BNP) and N-terminal proBNP (NT-proBNP) levels originate from the cardiac cells in response to cardiac strain. This may come from a pulmonary embolus, an acute severe infection (sepsis), or cardiomyopathy. But what is the relationship between these 2 cardiac biomarkers and preeclampsia? Can preeclampsia with severe features result in an abnormal rise in these 2 proteins exclusive to heart failure. Listen in to this real case scenario which our on call team cared for. 1.

Mastalgia is a common breast complaint in reproductive aged women. Mastalgia can be separated into three categories: 1) cyclical, 2) noncyclical, and 3) extramammary. Vitamin B6 is often cited as a homeopathic (non-prescription/pharmacological) remedy for simple mastalgia. Does the published data support its use? A newly published meta-analysis sheds light on the subject.1. Sharifipour, F., Siahkal, S.F. & Bagherinia, M.
