Children’s National at the Societies for Pediatric Urology Fall Congress

Providers from the Department of Urology at Children’s National Hospital attended the Societies for Pediatric Urology Fall Congress in October 2022 and shared a series of abstracts.

The abstracts look at unplanned healthcare use and missed visits among children with spina bifida, as well as factors associated with these outcomes. The team collected data from chart review and patient interviews to complete these projects. They considered clinical information, as well as demographic information and the childhood opportunity index, which is a composite measure that proxies social determinants of health, while accounting for how far a family lives from the emergency department.

Clinically, patients with more complex spina bifida (e.g., ventricular shunt or wheelchair use) were more likely to use the emergency department. Genitourinary and gastrointestinal problems were the most common reasons for emergency department use. Within the Spina Bifida Program at Children’s National, our providers are aggressively trying to reduce gastrointestinal complaints with a nurse practitioner dedicated to bowel management and working collaboratively with the Division of Colorectal and Pelvic Reconstruction.

A sobering finding from this research was that non-white patients with spina bifida at Children’s National were more likely to have had an emergency department visit between 2016-2020 after accounting for all other variables. This indicates a clear need for improving access, communication and quality of care for minority patients with spina bifida. We are increasingly developing our community partnerships with pediatricians and school nurses, and we are accessible by a direct phone line and email to allow for prompt support. We have also established clinics in Prince George’s County in Maryland which will bring the program closer to some minority communities.

The team also found that families of children with spina bifida scheduled for telemedicine visits were much more likely to miss a visit than a child without spina bifida or if the visit was in-person. This has led to changes in how we deploy telemedicine in this population, while still remaining nimble with the option of telemedicine or in-person visits. By screening the family’s ability and desire to use this modality, we hope to reduce missed visits overall.

growth of the Children's National Spina Bifida Program

A look at the Children’s National Spina Bifida Program

The Spina Bifida Program at Children’s National Hospital, led by co-directors, Christina Ho, M.D., and Briony Varda, M.D., has seen impressive growth and there are plans to continue expanding the program. Drs. Ho and Varda share insights on the multidisciplinary care being provided, along with their plans for the future of the program.

Q: How would you describe the growth of the program?

A: The growth of the Spina Bifida Program has been remarkable! The graph below really shows it all (more than a 25% increase in patient visits in the past year). We currently hold multidisciplinary programs including providers from neurosurgery (Robert Keating, M.D.), orthopaedic surgery (Matthew Oetgen, M.D.), physical medicine and rehabilitation (Mi Ran Shin, M.D.), urology (Briony Varda, M.D. and Christina Ho, M.D.), and expanded to include bowel management (Celicia Little, N.P.), gynecology (Allison Mayhew, M.D.) for our adolescent patients, as well as a dedicated nurse, Nicole Allentuck, R.N., and program associate, Christine Scott.

We are extremely proud of how the program has grown, particularly through the past two years, with the advent of our adolescent clinic and having a dedicated supportive team that ensures we have significant re-engagement of patients who had previously been lost to care. We are also working with the Prenatal Pediatrics Institute at Children’s National to enhance our prenatal care for patients diagnosed with spina bifida.

growth of the Children's National Spina Bifida Program

Q: What advancements is the spina bifida program making that benefit patients?

A: We have developed a transition clinic for our adolescent spina bifida patients to help address goals of care, independence with care and readiness for transition to adult providers. Our program coordinator, Celicia Little, N.P., also oversees our bowel management program to provide specialized bowel management care for our patients. We have been working on educational information specific to different areas within spina bifida, including how to catheterize, common medications, bowel management and anticipatory guidance. This helps to provide longevity for our patients as well.  We are evaluating ways to decrease visits to the emergency department and ensure appropriate antibiotic usage with proper diagnoses of urinary infections in patients who perform CIC.  To further our goal of providing longitudinal care within our program, we have engaged gynecology colleagues to see patients within our adolescent clinic and begin promoting independence through perpetuated discussions (e.g., are they able to schedule their own physician appointments or grocery shop for themselves?) in preparation for adult transitional care. Additionally, we readily offer telehealth visits for convenience and in hopes of easing access to care.

Q: Looking ahead, what’s next for the Spina Bifida Program? How will we continue to measure success?

A: We are excited to continue expanding our Spina Bifida Program. We currently care for more than 500 patients within the Washington, D.C., Maryland and Virginia areas. We want to continue to include patient narratives through our research initiatives to inform quality of care, including decreasing E.D. utilization and needless antibiotic use. We also want to expand our adolescent program to include sexual healthcare as they transition to adult care with our adult collaborators within MedStar and GWU. We would like to provide more comprehensive care, improve access to care, and ensure patients and families have utilization of the armamentaria of medical resources available at Children’s National.

Q&A with urologist Briony Varda

Briony Varda

Briony Varda, M.D., M.P.H., is fellowship trained in pediatric genitourinary reconstructive surgery and her subspecialty interests include the care of patients with spina bifida and the neurogenic bladder, cloacal anomalies, hydronephrosis, vesicoureteral reflux and posterior urethral valves, among others.

Children’s National Hospital recognizes many urologic disorders and illnesses that are unique to children. As such, we pride ourselves in working with top urology experts, including Briony Varda, M.D., M.P.H., pediatric urologist, who recently joined the Urology Division at Children’s National.

Dr. Varda is fellowship trained in pediatric genitourinary reconstructive surgery and her subspecialty interests include the care of patients with spina bifida and the neurogenic bladder, cloacal anomalies, hydronephrosis, vesicoureteral reflux and posterior urethral valves, among others.

Here, Dr. Varda tells us more about her work and what it means for the future of pediatric urology patients at Children’s National.

Q: Why did you decide to work in this field?

I have always thoroughly enjoyed working with children. They keep you on your toes, tell it straight, make you laugh and demonstrate unique resilience. At the same time, surgery allows me to work with my hands, while being creative and helping others. Finally, I had great mentors within pediatric urology who strongly influenced me in a positive way.

In sum, the kids, the surgery and the people led me here.

Q: What is the importance of urology care?

We have three goals in pediatric urology: protect the kidneys and bladder, prevent infection and help our patients stay dry.

Although it’s usually clear when kids have urinary tract infections or trouble with urinary accidents, it’s not always visible when there is a problem with the kidney or bladder. Urologic care is therefore important because it prevents long-term damage that might otherwise go unnoticed until it is too late. This is particularly true for patients with abnormal functioning of the bladder related to a neurologic cause, such as spina bifida or a tethered spinal cord.

Q: How has the program expanded and what are some of the most valuable changes you hope to see in the next couple of years?

Our Spina Bifida Program currently includes physicians from physical medicine and rehabilitation (PMNR), orthopedics, neurosurgery and urology. Our newest additions include a full-time nurse practitioner who facilitates care coordination and has a clinical expertise in bowel management, two new urologists (myself and Christina Ho, M.D.), and Mi Ran Shin, M.D., who is our new PMNR physician.

We are also collaborating closely with the new Pediatric Colorectal & Pelvic Reconstruction Division for patients who need advanced bowel management. These additions will go a long way to helping improve the day-to-day living of our patients and help improve their long-term medical outcomes.

In the coming year, we are anticipating welcoming another full-time nurse to our program, offering more patient-facing resources including a webpage focused on urodynamics and an array of new patient education materials. We are also hoping to establish a regional transitional care network for our adolescent and young-adult patients.

Q: The Colorectal Program at Children’s National includes three urologists. How does this collaboration allow for the care of more complex cases at this hospital?

We are fortunate to be part of the Colorectal Program here at Children’s National Hospital. We provide subspecialty expertise for patients born with anorectal malformations, including cloacal anomalies and cloacal exstrophy. Although historically considered a general surgery problem, patients with anorectal malformations have a high rate of concomitant conditions affecting their genitourinary anatomy and function. By coordinating clinical care and surgery within a multidisciplinary team, we provide comprehensive care for even the most complex patients – nothing goes unnoticed and each subspecialist provides a unique perspective on management as it relates to their field.  Along with ourselves and the colorectal surgeons, we regularly collaborate with gynecology, gastroenterology, interventional radiology and anesthesia.

Q:  What is some of the research you’re working on now that you’re looking forward to the most?

We are currently designing a set of research projects aimed at investigating low-value healthcare utilization (for example, emergency room use and inappropriate testing) among patients with spina bifida. I plan to investigate institutional patterns and then expand out to the Washington, D.C., Maryland, Virginia area and the national setting. By identifying patterns in low-value healthcare utilization and their associated factors, we can ideally improve care delivery for this special healthcare needs population.

We are also working on institutional protocols to enact recently published guidelines by the Spina Bifida Association and the CDC so that we can eventually contribute our own data to national registries. This will pave the way for increasingly rigorous spina bifida research in the future.

Billie Lou Short, M.D., received the Ninth Annual Mentorship Award in Clinical Science.

People joke that Billie Lou Short, M.D., chief of Children’s Division of Neonatology, invented extracorporeal membrane oxygenation, known as ECMO for short. While Dr. Short did not invent ECMO, under her leadership Children’s National was the first pediatric hospital to use it. And over decades Children’s staff have perfected its use to save the lives of tiny, vulnerable newborns by temporarily taking over for their struggling hearts and lungs. For two consecutive years, Children’s neonatal intensive care unit has been named the nation’s No. 1 for newborns by U.S. News & World Report. “Despite all of these accomplishments, Dr. Short’s best legacy is what she has done as a mentor to countless trainees, nurses and faculty she’s touched during their careers. She touches every type of clinical staff member who has come through our neonatal intensive care unit,” says An Massaro, M.D., director of residency research.

For these achievements, Dr. Short received the Ninth Annual Mentorship Award in Clinical Science.

Anna Penn, M.D., Ph.D., has provided new insights into the central role that the placental hormone allopregnanolone plays in orderly fetal brain development, and her research team has created novel experimental models that mimic some of the brain injuries often seen in very preterm babies – an essential step that informs future neuroprotective strategies. Dr. Penn, a clinical neonatologist and developmental neuroscientist, “has been a primary adviser for 40 mentees throughout their careers and embodies Children’s core values of Compassion, Commitment and Connection,” says Claire-Marie Vacher, Ph.D.

For these achievements, Dr. Penn was selected to receive the Ninth Annual Mentorship Award in Basic and Translational Science.

The mentorship awards for Drs. Short and Penn were among dozens of honors given in conjunction with “Frontiers in Innovation,” the Ninth Annual Research and Education Week (REW) at Children’s National. In addition to seven keynote lectures, more than 350 posters were submitted from researchers – from high-school students to full-time faculty – about basic and translational science, clinical research, community-based research, education, training and quality improvement; five poster presenters were showcased via Facebook Live events hosted by Children’s Hospital Foundation.

Two faculty members won twice: Vicki Freedenberg, Ph.D., APRN, for research about mindfulness-based stress reduction and Adeline (Wei Li) Koay, MBBS, MSc, for research related to HIV. So many women at every stage of their research careers took to the stage to accept honors that Naomi L.C. Luban, M.D., Vice Chair of Academic Affairs, quipped that “this day is power to women.”

Congenital Zika Viral Infection Linked to Significant Fetal Brain Abnormalities

PDF Version

What’s Known
According to the Centers for Disease Control and Prevention, Zika viral transmission is occurring extensively throughout Central and South America. Like other mosquito-borne viruses, Zika virus can be passed by pregnant women to developing fetuses. Unlike these other viruses, Zika has been implicated in a growing number of cases of Brazilian infants born with microcephaly, a condition characterized by undersized heads and severe brain damage. The precise strategy that the Zika virus uses to elude the immune system and the reason why fetal brain cells are particularly vulnerable remain unknown.

What’s New
A 33-year-old Finnish woman was 11 weeks pregnant when she and her husband traveled on vacation to Mexico, Guatemala, and Belize in late November 2015. The pair was bitten by mosquitoes during their trip, particularly in Guatemala. One day after returning to their Washington, DC home, the woman got sick, experiencing eye pain, muscle pain, a mild fever, and a rash. A series of early ultrasounds showed no sign of microcephaly or brain calcifications. A fetal ultrasound at the 19th week and a fetal MRI at the 20th week, however, revealed severe brain damage.

The brain of the 21-week-old aborted fetus weighed only 30 grams. Zika RNA, viral particles, and infectious virus were detected, and Zika virus isolated from the fetal brain remained infectious when tested. The concentration of virus was highest in the fetal brain, umbilical cord, and placenta. The mother remained infected with Zika virus at 21 weeks, some 10 weeks after her initial infection.

Questions for Future Research

  • Could serial measurements and blood tests more accurately detect and, ultimately, predict fetal abnormalities following Zika virus infection?
  • Why does the Zika virus replicate with ease within the womb?
  • At which stage of pregnancy are fetuses most vulnerable?
  • Which specific brain cells does Zika target?

Suspected domestic zika virus infection in Florida underscores the importance of ongoing vigilance

Drs. DeBiasi and du Plessis

Federal health officials continue to investigate the first possible cases of domestic Zika virus transmission in Florida. In light of the growing number of Zika infections, the vast majority of which have been associated with foreign travel, vigilance for additional cases is warranted – particularly as summer heat intensifies and mosquito populations grow. The Centers for Disease Control and Prevention (CDC) now advises that all pregnant women in the continental United States and U.S. territories be evaluated for Zika infection at each prenatal care visit. The CDC also recognizes that Zika-exposed infants will require long-term, multidisciplinary care.

In mid-May, Children’s National Health System Fetal Medicine Institute and Division of Pediatric Infectious Disease announced the formation of a Congenital Zika Virus Program to serve as a dedicated resource for referring clinicians and for pregnant women to receive counseling and science-driven answers about the impact of the Zika virus on pregnancies and newborns. Children’s clinicians have consulted on 30 pregnancies or births with potential Zika virus exposure and/or infection. As of Aug. 31, eight were Zika-positive or probable. One of the pregnancies was the subject of an article published by The New England Journal of Medicine.

”While we’re hopeful there are few local cases, the Congenital Zika Virus Program has been developing emergency response plans in collaboration with local departments of health to prepare for any eventuality,” says Roberta DeBiasi, MD, MS, Chief of the Division of Infectious Disease and Congenital Zika Virus Program co-leader.

Over the years, Children’s National has invested in equipment and highly trained personnel, building world-class expertise in infectious diseases, pediatric neurology, pediatric cardiology, genetics, neurodevelopment, and other specialties. Children’s clinicians are recognized leaders in next-generation imaging techniques, such as fetal MRI, which detects more subtle and earlier indications of impaired brain growth. A variety of divisions work together to offer multidisciplinary support and coordinated care to infants born with special needs. As the nation braces for the possible expansion of Zika virus infection to other states, Children’s National is facilitating the multi-step process of testing blood, urine, and tissue with state health departments, helping to ensure timely and precise information. Children’s National specialists guide Zika-affected pregnancies through the fetal period and are able to oversee and coordinate the care of Zika-affected infants after delivery. Care and clinical support is provided by a multidisciplinary team of pediatric neurologists, ophthalmologists, audiologists, physical and occupational therapists, infectious disease experts, and neurodevelopmental physicians.

The Children’s National multidisciplinary team includes:

  • Adre du Plessis, M.B.Ch.B., Director of the Fetal Medicine Institute, Chief of the Fetal and Transitional Medicine Division, and Congenital Zika Virus Program co-leader;
  • Roberta DeBiasi, M.D., M.S., Chief of the Division of Infectious Disease and Congenital Zika Virus Program co-leader;
  • Cara Biddle, M.D., M.P.H., Medical Director, Children’s Health Center, and a bilingual expert on complex care;
  • Dorothy Bulas, M.D., Radiologist in the Division of Diagnostic Imaging and Radiology;
  • Taeun Chang, M.D., Director, Neonatal Neurology Program in the Division of Neurophysiology, Epilepsy and Critical Care Neurology;
  • Sarah Mulkey, M.D., Ph.D., Fetal-Neonatal Neurologist, Fetal Medicine Institute;
  • Lindsay Pesacreta, M.S., F.N.P.-B.C., Board-Certified Family Nurse Practitioner; and
  • Gilbert Vezina, M.D., attending Radiologist in the Division of Diagnostic Imaging and Radiology and Director of the Neuroradiology Program.

New program provides science-driven answers about zika virus’s impact on pregnancies

Drs. DeBiasi and du Plessis

Each week, as temperatures rise, the likelihood increases that the United States will experience domestic Zika virus transmission. Indeed, such domestic Zika transmission already is occurring in Puerto Rico and the U.S. Virgin Islands. The Children’s National Health System Fetal Medicine Institute and Division of Pediatric Infectious Disease announced the formation of a Congenital Zika Virus Program to serve as a dedicated resource for referring clinicians and for pregnant women to receive counseling and science-driven answers about the impact of the Zika virus on their pregnancies.

Over years, Children’s National has invested in equipment and highly trained personnel, building expertise in infectious diseases, pediatric neurology, pediatric cardiology, genetics, neurodevelopment, and other specialties. Children’s clinicians are recognized as national leaders in next-generation imaging techniques, such as fetal MRI, and a variety of divisions work together to offer multidisciplinary support and coordinated care to infants born with special needs. As the nation prepares for the Zika virus, Children’s National is facilitating the multi-step process of blood testing, helping to ensure timely and precise information. Children’s National specialists are able to guide Zika-affected pregnancies through the fetal period and can oversee the care of Zika-affected infants after delivery. Care and clinical support is provided by a multidisciplinary team of pediatric neurologists, physical therapists, infectious disease experts, and neurodevelopmental physicians.
