  • Hypoplastic Left Heart Syndrome and a Trip Across State Lines

    Following a normal first trimester, a pregnant patient starts spotting. The patient’s care provider books an urgent ultrasound to see what is causing the bleeding. The main concerns are if the spotting is caused by a miscarriage or something else.

    Following the ultrasound, the technician calls in obstetrician Dr. Ashley Brant to review the results with the patient. There is a problem with the fetus’ heart — specifically, a condition called hypoplastic left heart syndrome. Essentially, the left side of the heart doesn’t develop normally and can’t pump blood in the way that it should.

    Hypoplastic left heart syndrome causes poor oxygenation, meaning the skin can be bluish or with dark discolorations. It also causes difficulty breathing, feeding, and lethargy. Treatment includes multiple surgeries after birth, and can even require a heart transplant. 

    Without treatment, the condition is fatal.

    The patient is offered genetic testing to determine if the heart condition is a symptom of a larger genetic disease. Regardless, the prognosis is grim.

    The patient meets with Dr. Brant to discuss all of the options, including continuing or ending the pregnancy. 

    “I think everybody who’s in a situation where they’re thinking about ending a pregnancy because of a major fetal anomaly, they are thinking about what is the kindest decision, the most loving decision that they can make for their baby,” shared Dr. Brant. “Nobody wants to be in this position. And they’re thinking about what the experience is going to be like for this child.”

    The patient makes the decision to end the pregnancy through the dilation and evacuation method. 

    However, the procedure cannot be performed in the state because of a heartbeat law in place at the time. 

    And so Dr. Brant refers the patient to an out-of-state clinic where the initial procedure to stop the heartbeat can be performed. But, in order to be where the patient has the support of the medical team she knows and who has been by her side, the patient returns to her home state for the final procedure. 

    “No one ever envisions themselves needing an abortion. No one ever thinks, ‘I want to have an abortion,’ before they’re in a position of needing one. I would just encourage compassion and empathy and trying to understand the life that someone else might be walking in.”

  • Pregnancy Reduction in a Twin Pregnancy

    A 35-year-old with several children discovers she is having a twin pregnancy. This is happy news, until a potential abnormality in twin B is found. 

    Twin B is measuring much smaller than twin A — almost a full 10 to 14 days behind — and there is fluid around the fetus. While it is too early to diagnose, it appears there is a brain abnormality.

    The patient, with a lot of apprehension and many questions, sees high-risk obstetrician Dr. Maeve Hopkins. Genetic testing is needed for decision-making — to help determine if twin B can survive or if the patient’s life and twin A are at risk, meaning a pregnancy reduction will need to be considered. Dr. Hopkins orders a biopsy of twin B’s placenta.

    The results from genetic testing reveal that twin B has three sets of chromosomes, instead of two. This results in a rare genetic condition that causes severe birth defects. Most pregnancies in this situation end in either miscarriage or stillbirth. While there are very rare cases of live births, survival is generally limited to an average of five to seven days.

    Carrying the fetus poses significant risk to both the patient and twin A. There could be a build up of amniotic fluid and difficulty swallowing for twin B, which could lead to preterm labor symptoms and birth, as well as stillbirth. Losing twin B in utero may increase the risk of losing twin A and put the patient at risk, too.

    In this case, there are two options.

    One is expectant management, which is essentially to wait and see. The other is a multi-fetal pregnancy reduction, where the cardiac activity of twin B is stopped, and the patient continues with a single twin pregnancy. While pregnancy reduction is considered a fairly safe procedure, there is a small risk that the patient could still lose twin A.

    “I think she was somewhat in shock,” Dr. Hopkins shared. “And I think she wanted some guidance, which is always difficult when patients want to know what to do … it’s a very personal, very familial decision for the patient … I generally say these are the risks to you, these are the possible outcomes, and these are the risks of a procedure. And a procedure likely carries less risk than continuing a twin pregnancy. And ultimately, she was able to make the decision.”

    The patient decides to move forward with the reduction procedure. 

    Reflecting back, Dr. Hopkins shared, “What I’ve learned practicing high-risk OB is when you face a situation like this with a patient, it is impossible to know what decision that you would make if you were in that clinical situation … So just taking a step back and not necessarily trying to put yourself in the patient’s shoes, but just stepping back and giving the information and just listening to the patient. I think as high-risk obstetricians, we’re often the ones who have these stories and who see these patients, whether we’re political or not, that’s a life-saving procedure for us many times.”

  • The Complicated Decision-Making of a Molar Pregnancy and an Intrauterine Pregnancy

    A pregnant person is referred early in pregnancy to high-risk obstetrician Dr. Stacey Ehrenberg after an ultrasound detects an abnormally developing placenta. Dr. Ehrenberg diagnoses the patient with a molar pregnancy; a placenta that forms into a benign tumor with the potential to become cancerous. While the molar pregnancy will not survive, the patient also has a viable intrauterine pregnancy.

    Faced with this diagnosis, Dr. Ehrenberg counsels her patient about the risks of continuing or discontinuing the pregnancy. If the decision is made to continue, the patient risks developing mirror syndrome, a life-threatening condition marked by hypertension and edema. There is also significant risk of bleeding if any of the abnormal tissue is removed.

    If the decision is made to end the pregnancy, the patient faces the risks of any procedure done in a hospital; bleeding, infection, and damage to the surrounding organs, although this happens in less than 1% of cases. Regardless of the patient’s choice, Dr. Ehrenberg emphasizes that she and her team will support the patient, no matter what. 

    The patient decides to continue the pregnancy. Dr. Ehrenberg and team develop a care plan to track both the molar pregnancy and the intrauterine pregnancy with weekly ultrasounds and blood pressure measurements. 

    “I really watched her struggle throughout the pregnancy knowing that she knew that at some point the scale was going to tip and that this would no longer be safe for her to continue,” shared Dr. Ehrenberg. “Her hope, as was ours, was that she would be able to get far enough in pregnancy where the baby would be able to survive. She knew that this would probably be an extremely premature baby, but she was willing to take that risk to start her family.”

    But at 19 weeks, everything changes. 

    “I didn’t need vital signs. I didn’t need to do a physical exam to know something wasn’t right,” remembered Dr. Ehrenberg. “We got vital signs on her and I did a physical exam, and it was very clear to me that she had mirror syndrome and then we had to have the very difficult conversation that we knew that the baby was not yet viable, but it was no longer safe for her to remain pregnant.”

    The decision is clear: the only viable option is dilation and evacuation. 

    But the procedure is not without serious complications and risks. 

    “… These pregnancy complications are so complex,” shared Dr. Ehrenberg. “The physical aspects of it, the emotional aspects of it, the financial aspects of it … So I really just would love to see more kindness towards other people, more tolerance towards other people, more understanding that we don’t understand all the time where other people are coming from and what they’ve been through.”

  • Non-Specific Symptoms Lead to Complicated Diagnosis

    It starts small. A slight pain in the foot, followed by an achy shoulder. There's some fatigue. The type of non-specific symptoms that often go ignored … until they can’t be anymore.

    A 37-year-old visits the family doctor, complaining of foot, shoulder and chest pain that progresses over weeks. And she's really tired. Otherwise, there’s nothing notable. 

    She's just a busy parent. Being tired is normal, right? 

    Sometimes that’s true, but in this case, this would prove to be a dangerous assumption. 

    She visits her primary care provider who decides to run X-rays. There’s nothing to note other than an expanded area of cartilage at the end of the sixth rib. The doctor doesn’t think much of it at the time, but this would prove pivotal to solving the case. 

    The patient is prescribed physical therapy, but it doesn’t help. It actually makes things worse. 

    “She's getting very fatigued to the point where she's having to lay down in the afternoons. She can't really do her full family activities,” shares Dr. Suzanne Jan De Beur, an endocrinologist with a specialty in metabolic bone disorders at Johns Hopkins University School of Medicine in Baltimore, Maryland. “She gets terrible pain … And then eventually she was found to have a left hip fracture and needed surgery to repair the hip fracture.”

    This incredible progression — a hip fracture with no trauma at 39 years old — leads to more tests. She’s diagnosed with celiac disease, a wheat allergy that can cause weak bones from not absorbing vitamin D and other nutrients into the bones. This explains the fractures, but not the muscle weakness.

    She’s compliant with her celiac therapy, but it keeps getting worse — to the point of needing a walker. This is when the patient sees Dr. Jan De Beur. 

    It’s at this time that a very small discovery leads to a very big diagnosis. 

    It also leads to many lessons — one being to not only zoom in on one specific symptom, but to zoom out on a case over time so you can put the puzzle pieces of non-specific symptoms together and find your diagnosis.

  • A Lump on the Skull and the Misdiagnosis of a Rare Bone Disease

    In 1964, Nancy, a 5-year-old, is having her evening bath when her parents discover she has a lump on the skull the size of a grapefruit. This would mark the onset of a mysterious and debilitating disease that researchers are still struggling to understand. 

    Over the next 40 days, medical professionals struggled to discover what was causing the lump on the skull. Each test seemed to exacerbate the swelling in Nancy’s neck. In hindsight, that was a big clue, but it took doctors a while to recognize it. 

    Instead, what happened next was a common mistake when it comes to patients with this disease. Nancy was diagnosed with terminal cancer. Doctors said she had less than a year. 

    Yet, over the next few months, Nancy’s condition didn’t progress. She actually seemed to get better. Over the next few months, she was taken to a series of specialists. It was finally an oncologist who noticed something that was pivotal to her diagnosis … her toes. Misshapen big toes — generally short and bending inward — are a hallmark of Nancy’s disease. 

    While Nancy had several telltale signs of the disease, diagnosing rare diseases is difficult in part because they’re exactly that: rare. 

    “I can see how a practicing physician may feel a rare disease, ‘I’m never going to see it.’ But [this disease] is so striking that I think once you see someone with the disease … the image stays in your mind and even if someone, as a general internist or a pediatrician, never expects to see the case, you never know,” shares Dr. Eileen Shore, a medical researcher and geneticist specializing in musculoskeletal disorders at the University of Pennsylvania School of Medicine. 

    And early diagnosis of this — and other rare diseases — is crucial, not only for treatment but to avoid diagnostic tests that can harm patients. While Nancy did finally receive a definitive diagnosis, many of the earlier diagnostic tests were actually causing more harm than good. 

    “If you just have that in the back of your mind, that you have a vague image of what [it] is and see a patient who you think might have it,” says Dr. Shore, “to send a referral and get it confirmed, just think of the difference it would make in that family’s life.”

  • Metatarsal Bone Fractures and a Rare Bone Disease Hiding in Plain Site

    A patient in her mid-50s complains of foot and leg pain. She’s post-menopausal with low bone density. A classic case of post-menopausal osteoporosis.

    Not exactly. 

    And it won’t start to become clear until it gets to the point of her having repeated metatarsal bone fractures.

    Let’s go back a little. It’s 2005. Our patient visits her family doctor complaining of pain in her legs and feet. But the discomfort she’s experiencing isn’t your typical aches and pains associated with aging. 

    “She develops a lot of [foot and leg] pain … So much so that she required pain management for this pain and her gate started to become affected,” shares Dr. Katherine Dahir, a professor of medicine at Vanderbilt University, who specializes in metabolic bone disease.

    Her gait becomes wobbly and she’s experiencing an acceleration of degenerative changes in her spine. An osteoporosis screening reveals she has low bone density. She’s diagnosed with post-menopausal osteoporosis and is treated with bisphosphonates, the standard of care for patients with osteoporosis. 

    And this is when things get much more complicated. 

    Although all signs show an improvement in bone density, she begins to experience metatarsal bone fractures, which is highly unusual with osteoporosis. And not only does she have these unusual fractures, the fractures will not heal.  

    “And so that’s when you need to put your thinking cap on and try and figure out, why is this patient a treatment failure?” says Dr. Dahir.

    To solve the case, the patient’s team studies her labs and finds a missing flag. “… It was called alkaline phosphatase, which is seen in a routine chemistry panel. Back at that time, it was only flagged if it was above the normal reference range because that usually indicates liver disease, but it wasn’t flagged if it was below the normal reference range because that was considered to be non-significant.” 

    But this finding would prove to be very significant. Combined with new research at the time, it helped identify a diagnosis for this patient — showing the importance of medical research that leads to more treatment options and more hope for patients.
