Coming together as a team for the good of the baby

March 12, 2019

Children’s National has a new program to care for children who have severe bronchopulmonary dysplasia, a serious complication of preterm birth.

Around the 1-year-old’s crib is a tight circle of smiling adults, and at the foot of his bed is a menagerie of plush animals, each a different color and texture and shape to spark his curiosity and sharpen his intellect.

Gone are the days a newborn with extremely complex medical needs like Elijah would transfer from the neonatal intensive care unit (NICU) to the pediatric intensive care unit and transition through a couple of other hospital units by the time he was discharged. Gone are the days when he’d see a variety of new physician faces at every stop. And gone are the days he’d be confined to his room, divorced from the sights and sounds and scents of the outside world, stimulation that helps little baby’s neural networks grow stronger.

Children’s National has a new program designed to meet the unique needs of children like Elijah who have severe bronchopulmonary dysplasia (BPD), a common complication of preterm birth.

“It’s more forward-thinking – and I mean thinking for the future of each individual baby, and it’s allowing the baby to have one team and one location to take advantage of a deep knowledge of and relationship with that baby and family,” says Robin Steinhorn, M.D. Dr. Steinhorn is senior vice president of the Center for Hospital-Based Specialties and one of Children’s multidisciplinary team members who visited Elijah’s bed twice weekly during his lengthy hospitalization and who continues to see him regularly during outpatient visits.

“The pulmonologist, the neonatologist, the respiratory therapist, the physical therapist, the dietitian, the cardiologist – we all come as a team to work together for the good of the baby,” Dr. Steinhorn adds. “We stick with these babies through thick and thin. We will stick with that baby with this team and this location until they are ready to go home – and beyond.”

BPD, a serious lung condition, mostly affects extremely low birthweight preterm babies whose lungs were designed to continue developing inside the womb until the pregnancy reaches full term. Often born months before their due dates, these extremely vulnerable newborns have immature organs, including the lungs, which are not ready for the task of breathing air. Children’s program targets infants who experience respiratory failure from BPD. The respiratory support required for these infants ranges from oxygen delivered through a nasal cannula to mechanical ventilators.

About 1 percent of all preterm births are extremely low birthweight, or less than 1,500 grams. Within that group, up to 40 percent will develop BPD. While they represent a small percentage of overall births, these very sick babies need comprehensive, focused care for the first few years of their lives. And some infants with severe BPD also have pulmonary hypertension which, at Children’s National, is co-managed by cardiology and pulmonary specialists.

Children’s BPD team not only focuses on the child’s survival and medical care, they focus on the neurodevelopmental and social care that a baby needs to thrive. From enhanced nutrition to occupational and physical therapy to a regular sleep cycle, the goal is to help these babies achieve their full potential.

“These babies are at tremendous risk for long-term developmental issues. Everything we do is geared to alleviate that,” adds John T. Berger III, M.D., director of Children’s Pulmonary Hypertension Program.

“Our NICU care is more focused, comprehensive and consistent,” agrees Mariam Said, M.D., a neonatologist on the team. “We’re also optimizing the timing of care and diagnostic testing that will directly impact health outcomes.”

Leaving no detail overlooked, the team also ensures that infants have age-appropriate developmental stimuli, like toys, and push for early mobility by getting children up and out of bed and into a chair or riding in a wagon.

“The standard approach is to keep the baby in a room with limited physical or occupational therapy and a lack of appropriate stimulation,” says Geovanny Perez, M.D., a pulmonologist on the team. “A normal baby interacts with their environment inside the home and outside the home. We aim to mimic that within the hospital environment.”

Dr. Steinhorn, who had long dreamed of creating this comprehensive team care approach adds that “it’s been so gratifying to see it adopted and embraced so quickly by Children’s NICU caregivers.”

What Children’s has learned about congenital Zika infection

October 18, 2017

Roberta DeBiasi, M.D., M.S., outlined lessons learned during a pediatric virology workshop at IDWeek2017, one of three such Zika presentations led by Children’s National research-clinicians during this year’s meeting of pediatric infectious disease specialists.

The Congenital Zika Virus Program at Children’s National Health System provides a range of advanced testing and services for exposed and infected fetuses and newborns. Data that the program has gathered in evaluating and managing Zika-affected pregnancies and births may offer instructive insights to other centers developing similar programs.

The program evaluated 36 pregnant women and their fetuses from January 2016 through May 2017. Another 14 women and their infants were referred to the Zika program for postnatal consultations during that time.

“As the days grow shorter and temperatures drop, we continue to receive referrals to our Zika program, and this is a testament to the critical need it fulfills in the greater metropolitan D.C. region,” says Roberta L. DeBiasi, M.D., M.S., chief of the Division of Pediatric Infectious Diseases and co-leader of the program. “Our multidisciplinary team now has consulted on 90 dyads (mothers and their Zika-affected fetuses/infants). The lessons we learned about when and how these women were infected and how their offspring were affected by Zika may be instructive to institutions considering launching their own programs.”

Dr. DeBiasi outlined lessons learned during a pediatric virology workshop at IDWeek2017, one of three such Zika presentations led by Children’s National research-clinicians during this year’s meeting of pediatric infectious disease specialists.

“The Zika virus continues to circulate in dozens of nations, from Angola to the U.S. Virgin Islands. Clinicians considering a strategic approach to managing pregnancies complicated by Zika may consider enlisting an array of specialists to attend to infants’ complex care needs, including experts in fetal imaging, pediatric infectious disease, physical therapists, audiologists, ophthalmologists and radiologists skilled at reading serial magnetic resonance images as well as ultrasounds,” Dr. DeBiasi says. “At Children’s we have a devoted Zika hotline to triage patient and family concerns. We provide detailed instructions for referring institutions explaining protocols before and after childbirth, and we provide continuing education for health care professionals.”

Of the 36 pregnant women possibly exposed to Zika during pregnancy seen in the program’s first year, 32 lived in the United States and traveled to countries where Zika virus was circulating. Two women had partners who traveled to Zika hot zones. And two moved to the Washington region from places where Zika is endemic. Including the postnatal cases, 89 percent of patients had been bitten by Zika-tainted mosquitoes, while 48 percent of women could have been exposed to Zika via sex with an infected partner.

Twenty percent of the women were exposed before conception; 46 percent were exposed to Zika in the first trimester of pregnancy; 26 percent were exposed in the second trimester; and 8 percent were exposed in the final trimester. In only six of 50 cases (12 percent) did the Zika-infected individual experience symptoms.

Zika infection can be confirmed by detecting viral fragments but only if the test occurs shortly after infection. Twenty-four of the 50 women (nearly 50 percent) arrived for a Zika consultation outside that 12-week testing window. Eleven women (22 percent) had confirmed Zika infection and another 28 percent tested positive for the broader family of flavivirus infections that includes Zika. Another detection method picks up antibodies that the body produces to neutralize Zika virus. For seven women (14 percent), Zika infection was ruled out by either testing method.

“Tragically, four fetuses had severe Zika-related birth defects,” Dr. DeBiasi says. “Due to the gravity of those abnormalities, two pregnancies were not carried to term. The third pregnancy was carried to term, but the infant died immediately after birth. The fourth pregnancy was carried to term, but that infant survived less than one year.”

Multidisciplinary approach to hydrocephalus care

February 23, 2017

Reflective of the myriad symptoms and complications that can accompany hydrocephalus, a multidisciplinary team at Children’s National works with patients and families for much of childhood.

The Doppler image on the oversized computer screen shows the path taken by blood as it flows through the newborn’s brain, with bright blue distinguishing blood moving through the middle cerebral artery toward the frontal lobe and bright red depicting blood coursing away. Pitch black zones indicate ventricles, cavities through which cerebrospinal fluid usually flows and where hydrocephalus can get its start.

The buildup of excess cerebrospinal fluid in the brain can begin in the womb and can be detected by fetal magnetic resonance imaging. Hydrocephalus also can crop up after birth due to trauma to the head, an infection, a brain tumor or bleeding in the brain, according to the National Institutes of Health. An estimated 1 to 2 per 1,000 newborns have hydrocephalus at birth.

When parents learn of the hydrocephalus diagnosis, their first question tends to be “Is my child going to be OK?” says Suresh Magge, M.D., a pediatric neurosurgeon at Children’s National Health System.

“We have a number of ways to treat hydrocephalus. It is one of the most common conditions that pediatric neurosurgeons treat,” Dr. Magge adds.

Unlike fluid build-up elsewhere in the body where there are escape routes, with hydrocephalus spinal fluid becomes trapped in the brain. To remove it, surgeons typically implant a flexible tube called a shunt that drains excess fluid into the abdomen, an interim stop before it is flushed away. Another surgical technique, called an endoscopic third ventriculostomy has the ability to drain excess fluid without inserting a shunt, but it only works for select types of hydrocephalus, Dr. Magge adds.

For the third year, Dr. Magge is helping to organize the Hydrocephalus Education Day on Feb. 25, a free event that offers parents an opportunity to learn more about the condition.

Reflective of the myriad symptoms and complications that can accompany hydrocephalus, such as epilepsy, cerebral palsy, cortical vision impairment and global delays, a multidisciplinary team at Children’s National works with patients and families for much of childhood.

Neuropsychologist Yael Granader, Ph.D., works with children ages 4 and older who have a variety of developmental and medical conditions. Granader is most likely to see children and adolescents with hydrocephalus once they become medically stable in order to assist in devising a plan for school support services and therapeutic interventions. Her assessments can last an entire day as she administers a variety of tasks that evaluate how the child thinks and learns, such as discerning patterns, assembling puzzles, defining words, and listening to and remembering information.

Neuropsychologists work with schools in order to help create the most successful academic environment for the child. For example, some children may struggle to visually track across a page accurately while reading; providing a bookmark to follow beneath the line is a helpful and simple accommodation to put in place. Support for physical limitations also are discussed with schools in order to incorporate adaptive physical education or to allow use of an elevator in school.

“Every child affected by hydrocephalus is so different. Every parent should know that their child can learn,” Granader says. “We’re going to find the best, most supportive environment for them. We are with them on their journey and, every few years, things will change. We want to be there to help with emerging concerns.”

Another team member, Justin Burton, M.D., a pediatric rehabilitation specialist, says rehabilitation medicine’s “piece of the puzzle is doing whatever I can to help the kids function better.” That means dressing, going to the bathroom, eating and walking independently. With babies who have stiff, tight muscles, that can mean helping them through stretches, braces and medicine management to move muscles smoothly in just the way their growing bodies want. Personalized care plans for toddlers can include maintaining a regular sleep-wake cycle, increasing attention span and strengthening such developmental skills as walking, running and climbing stairs. For kids 5 and older, the focus shifts more to academic readiness, since those youths’ “full-time job” is to become great students, Dr. Burton says.

The area of the hospital where children work on rehabilitation is an explosion of color and sounds, including oversized balance balls of varying dimensions in bright primary colors, portable basketball hoops with flexible rims at multiple heights, a set of foam stairs, parallel bars, a climbing device that looks like the entry to playground monkey bars and a chatterbox toy that lets a patient know when she has opened and closed the toy’s doors correctly.

“We end up taking care of these kids for years and years,” he adds. “I always love seeing the kids get back to walking and talking and getting back to school. If we can get them back out in the world and they’re doing things just like every other kid, that’s success.”

Meanwhile, Dr. Magge says research continues to expand the range of interventions and to improve outcomes for patients with hydrocephalus, including:

Fluid dynamics of cerebrospinal fluid
Optimal ways to drain excess fluid
Improving understanding of why shunts block
Definitively characterizing post-hemorrhagic ventricular dilation.

Unlike spina bifida, which sometimes can be corrected in utero at some health institutions, hydrocephalus cannot be corrected in the womb. “While we have come a long way in treating hydrocephalus, there is still a lot of work to be done. We continue to learn more about hydrocephalus with the aim of continually improving treatments,” Dr. Magge says.

During a recent office visit, 5-year-old Abagail’s head circumference had measured ¼ centimeter of growth, an encouraging trend, Robert Keating, M.D., Children’s Chief of Neurosurgery, tells the girl’s mother, Melissa J. Kopolow McCall. According to Kopolow McCall, who co-chairs the Hydrocephalus Association DC Community Network, it is “hugely” important that Children’s National infuses its clinical care with the latest research insights. “I have to have hope that she is not going to be facing a lifetime of brain surgery, and the research is what gives me the hope.”
