Dr. Chapa’s OBGYN Clinical Pearls

In 2018, the ACOG recommended immediate induction of labor/delivery for patients with PPROM, who had sure gestational dating, and were at 34 weeks and 0 days or more. This was in order to reduce the risk of neonatal sepsis. This changed, however, in 2020 with ACOG Practice Bulletin 217 which discussed expected management for PPROM in the late preterm interval. Nonetheless, as is our tagline for th...

As part of our medical training and education, we often learn diagnoses in isolation. For example, we have learned that Proliferative Endometrium on EMB is a non-pathological finding. That result can be left alone without therapy, correct? But what if that is found in the context of a postmenopausal patient. Is it still considered a nonpathological finding? In this episode, we will summarize the c...

Marginal cord insertions can be found on antenatal ultrasound. What is the data regarding marginal cord insertion and adverse neonatal outcomes? Is there a relationship, or is this a benign finding? Are serial growth ultrasounds recommended? What about antepartum fetal surveillance for isolated marginal cord insertion? In this episode, we will review the latest data on pregnancies with marginal co...

This is our impromptu podcast session in-between patients in our OB Clinic. In this episode, Dr. Leon-Arango (Senior Resident) highlights the importance of looking “deeper” into a patient’s persistent complaint of depression despite a negative PHQ9 score, based on her encounter from today. This real example of a physician’s perception of need for intervention likely helped to change the trajectory...

The first case of placenta accreta listed on PubMed was reported in 1927 by Dr D.S. Forster out of Montreal. That was 1 case in 8000 deliveries! Now, according to the National Accreta Foundation, PAS occurs in 1 in 272 pregnancies. How did we get to this rate? In this episode we will highlight data from ACOG, SMFM, and the National Accreta Foundation. We will highlight key ultrasound markers, pati...

Delayed cord clamping (DCC) provides vital placental transfusion to newborns and is endorsed by ACOG, SMFM, March of Dimes, and the ACNM. However, DCC in nonvigorous newborns may not be provided owing to a perceived need for immediate resuscitation. Umbilical cord milking, in late-term and full-term neonates, is an alternative in these cases. In December 2020, the ACOG’s Committee Opinion stated a...

Historically, IUDs where considered contraindicated in a patient with a prior ectopic pregnancy. This was due to concerns that IUDs may be causative of tubal gestations. Is this true? Are IUDs contraindicated with a past history of ectopic pregnancy? In this episode we will review the data from the CHOICE project, the CDC (US), and the Royal College of OBGYN (UK). We will also summarize key findin...

A 2020 publication from JAMA Pediatrics reported that labor epidural analgesia may be associated with an up to 37% increased risk of offspring autism spectrum disorder. The ASA has rejected those results based on methodologic limitations of the study, the lack of biological plausibility. But some remain fearful of labor epidurals because of that publication. In February 2023, a new publication in...

Platelet Rich Plasma (PRP) therapy is a HOT and TRENDY item right now. PRP use was initiated in sports medicine in the 1970s. It has since expanded into many medical specialty fields, and now it is being heralded as the new hope for diminished ovarian reserve for those desiring pregnancy…even in menopause! Can injecting the ovaries with PRP really rejuvenate the ovary? We’ll examine the evidence a...

Routine, repetitive urine dipsticks (meaning at each prenatal visit) were introduced into prenatal care back in the 1960s and 70s. The idea was to act as an early screen for bacteriuria (ASB), proteinuria as a screen for preeclampsia, and glycosuria as a screen for GDM. That was based more on expert opinion rather than clinical trials. The utility of urine dipstick testing in pregnant women has be...

Paragard, Mirena, and Liletta IUDs are the most effective types of emergency contraception. Data from the 1980s, now seemingly forgotten, showed that IUDs work primarily on inhibition of fertilization rather than implantation effects. Nonetheless, misperceptions regarding the IUDs mechanisms of action persist, with some websites stating IUDs are abortive agents. Do IUDs cause abortion? Let’s exami...

“Placentophagy” is not a new concept. Most non-human mammals eat their placentas after giving birth but humans, historically, have not. Is there evidence to support this practice? Where did this idea come from? How did Rolling Stone magazine help launch this phenomenon back in the 1970s? Is Kim Kardashian onto something cutting edge by advocating for Placental encapsulation? In this episode we wil...

The American College of Obstetricians and Gynecologists supports the use of both low-dose and high-dose oxytocin regimens to induce and augment labor, but does not specify MAXIMUM DOSE RATES. Most hospitals, however, have protocols that impose a maximum dose rate of oxytocin infusion. Is this evidence-based? Is there a danger with going above a certain threshold of infusion, for example, greater t...

The ACOG states, “In spite of its unproven value, antepartum fetal surveillance is widely integrated into clinical practice in the developed world”. Antepartum fetal surveillance can be done by a variety of techniques and, despite its unproven value, is a mainstay of obstetrical management. At what BMI should we offer fetal surveillance? Is this current BMI or pre-pregnancy BMI? And what about adv...

Breech presentation at term occurs in approximately 3 to 4% of pregnancies. While the vast majority are simply chance events, breech presentation could be a marker of other fetal comorbid conditions. When should ECV be attempted? Does the ACOG recognize neuraxial analgesia as a tool to increase ECV success rates? What’s better spinal or epidural block? What are relative contraindications to ECV? I...

On some current social media channels, there is a hot debate as to why professional medical societies still recommend prenatal folic acid compared to the more “biologically, active” L-methylfolate. Are they onto something here? Published data has shown that anywhere from 40-60% of the general population may have an MTHFR mutation leading to the inability to process folic acid. Should we be screeni...

Currently on social media, there seems to be an interest in prenatal choline supplementation. Choline, a B vitamin, is not typically within standard prenatal vitamins. Is this micronutrient important for prenatal supplementation? What do professional/medical societies have to say regarding prenatal supplementation? What’s the data? In this episode, we will summarize choline’s role in fetal/newborn...

Uterine fibroids are benign tumors that arise from a single genetically altered myometrial stem cell under the influence of gonadal hormones. Traditionally, it has been taught that fibroids universally diminish in size after menopause. However, an article published in 2021 showed a possibility of fibroid growth after menopause in overweight/obese women. Do fibroids need surveillance in menopause?...

I am a fan of the original hit TV show, “ER”. Although mostly melodramatic and outside of bounds of reality Medicine, one episode (season 6, episode 6) has a valuable life lesson for all of us. I originally viewed that episode when it was live and current, and I have never forgotten the message. In this episode, will discuss this important life lesson learned, and I promise you won’t be the same t...

In January 2023, a new publication in Obstetrics and Gynecology- the Green Journal, will highlight the disheartening statements being made on social media (TikTok) regarding IUDs. IUDs are highly effective forms of contraception and the progesterone releasing variety have significant non-contraceptive benefits. Most of the dissatisfaction stated on social media surrounds pain during insertion. Do...

Pre-operative vaginal preparation before gynecological surgery has unquestionable benefit for the prevention of postop infectious morbidity. Does the same hold true for vaginal prep at C-section? There has been over a decade of data, but a new publication- soon to be released in AJOG- is calling previous results into question. Does iodine work as a vaginal prep? What about chlorhexidine? There’s a...

Surgical site infection (SSI) is the most common complication resulting from cesarean section. Despite advances in infection control, SSIs remain a significant post-op burden, to the patient first, and to the healthcare system second. Negative pressure wound therapy devices (NPWT) are a potential solution to post C-section. wound infections/complications. Do these devices prevent incisional wound...

Traditionally, the CDC has recommended delaying IUD insertion for 3 months in a woman diagnosed with asymptomatic, cervical Gonorrheal or Chlamydial infection. This is to first confirm a negative test of cure. However, this leaves the patient at a greater risk of unplanned pregnancy compared to the risk of PID. Is this really the most evidence-based approach? The CHOICE CONTRACEPTIVE Study data pr...

In the upcoming (May) 2023 ACOG Annual Clinical Meeting, the College will have a highlighted session to “redesign, prenatal care”. The traditional model of prenatal care includes 12 to 14 in-person visits. However, there is no data that supports the theory that adverse outcomes are reduced by the number of prenatal contact visits. In 2020, at the height of the COVID-19 pandemic, women’s healthcare...

Did you know that not all cases of a single umbilical artery (SUA) result in a 2-vessel cord? Some umbilical cords with a SUA still have 3 vessels! How is that possible? Although SUA is only found between 0.2 to 1% of all live births, they can have important clinical implications. Although sonographic absence of other congenital anomalies is very reassuring (isolated SUA), some fetal conditions ma...
