Children’s National Hospital in Washington, D.C., was ranked in the top 10 nationally in the U.S. News & World Report 2021-22 Best Children’s Hospitals annual rankings. This marks the fifth straight year Children’s National has made the Honor Roll list, which ranks the top 10 children’s hospitals nationwide. In addition, its neonatology program, which provides newborn intensive care, ranked No.1 among all children’s hospitals for the fifth year in a row.

For the eleventh straight year, Children’s National also ranked in all 10 specialty services, with seven specialties ranked in the top 10.

“It is always spectacular to be named one of the nation’s best children’s hospitals, but this year more than ever,” says Kurt Newman, M.D., president and CEO of Children’s National. “Every member of our organization helped us achieve this level of excellence, and they did it while sacrificing so much in order to help our country respond to and recover from the COVID-19 pandemic.”

“When choosing a hospital for a sick child, many parents want specialized expertise, convenience and caring medical professionals,” said Ben Harder, chief of health analysis and managing editor at U.S. News. “The Best Children’s Hospitals rankings have always highlighted hospitals that excel in specialized care. As the pandemic continues to affect travel, finding high-quality care close to home has never been more important.”

The annual rankings are the most comprehensive source of quality-related information on U.S. pediatric hospitals. The rankings recognize the nation’s top 50 pediatric hospitals based on a scoring system developed by U.S. News. The top 10 scorers are awarded a distinction called the Honor Roll.

The bulk of the score for each specialty service is based on quality and outcomes data. The process includes a survey of relevant specialists across the country, who are asked to list hospitals they believe provide the best care for patients with the most complex conditions.

Below are links to the seven Children’s National specialty services that U.S. News ranked in the top 10 nationally:

The other three specialties ranked among the top 50 were cardiology and heart surgery, gastroenterology and gastro-intestinal surgery, and urology.

Illustration of brain hemispheres

New research finds young children process language in both hemispheres of the brain, which could help compensation after a neural injury. This is unlike adults who process most language tasks in one side (usually the left) of their brain’s two hemispheres. It suggests a possible reason why children often seem to recover from brain injury more easily than adults.

New research finds young children process language in both hemispheres of the brain, which could help compensate after a neural injury. The study, published Sept. 8, 2020, in PNAS, says this is unlike adults who process most language tasks in one side (usually the left) of their brain’s two hemispheres. It suggests a possible reason why children often seem to recover from brain injury more easily than adults.

We talked with researcher William D. Gaillard, M.D., chief of the Divisions of Child Neurology, Epilepsy and Neurophysiology at Children’s National Hospital, to discuss the importance of this work.

Q: Tell us a little bit about this study.

A: This is a study we did with our colleagues at Georgetown University Medical Center, using fMRI to map brain regions that are used to process language across development. What we found was that younger children have more bilateral “activation” in language processing regions, the traditional left and homotopic regions in the right. With aging there is consolidation that becomes more left lateralized. This process is most clearly seen in the frontal brain regions, called Broca’s area, where the right activation diminishes over age

Q: Why are these findings important?

A: It’s important because this work provides evidence for how cognitive systems, and the neural networks that underlie them, become consolidated and lateralized over time during development. It provides insights into principles of the development of cognitive systems.

The timeline for lateralization of language systems means that the cognitive systems that sustain language are “plastic” – that is the right hemisphere can sustain language functions in the setting of injury to the left hemisphere until around 10 years of age.

Q: What excites you about this work?

A: This is part of a larger collaborative effort that is mapping out the consolidation of cognitive systems across development (language, visual spatial, memory and working memory). This work will help us to understand the limits of brain plasticity in the setting of injury caused by stroke or epilepsy, which could have benefits down the road to helping patients recover from these types of events.

Q: How is Children’s National leading the ongoing discovery in this space?

A: It is a true team effort. We are working with colleagues at Georgetown University Medical Center, MedStar National Rehabilitation Network and Johns Hopkins Medicine. Team members come from diverse backgrounds and scientific skills. We are one of the leading groups using advanced functional imaging to investigate brain development of critical cognitive systems and their response to brain injury.

The Child Neurology Foundation has awarded Youssef A. Kousa, M.S., D.O., Ph.D., the 2020 Pediatric Epilepsy Research Foundation Shields Research Grant. The funds will support his work on identifying genetic risk factors in congenital Zika syndrome.

The Child Neurology Foundation has awarded Youssef A. Kousa, M.S., D.O., Ph.D., physician-scientist within the Division of Neurology at Children’s National Hospital, and founder and director of the Zika Genetics Consortium, the 2020 Pediatric Epilepsy Research Foundation Shields Research Grant. The funds will support his work on identifying genetic risk factors in congenital Zika syndrome.

This prestigious grant provides $100,000 of research funding to help identify treatments and cures for pediatric neurologic diseases. It will allow Dr. Kousa to test the hypothesis that rare genetic variants in individuals contributed to being affected with congenital Zika syndrome and the severity of the phenotype for those who were affected.

“Despite decades of research, identifying those at greatest risk of congenital infection or being severely affected remains an elusive goal,” says Dr. Kousa. “This research is important because identifying genetic risk or protective factors for developmental brain malformations can help teach us how the brain develops.”

Youssef Kousa

In 2015, Dr. Kousa established the Zika Genetic Consortium to investigate whether maternal and fetal genetic factors can modify the risk of brain injury from congenital infections.

Dr. Kousa adds that this work will provide key insights into maternal and fetal genetic factors that can contribute to brain malformations. The hope is that these insights may one day translate into targeted prevention efforts.

“Dr. Kousa’s project is very creative and has a fantastic opportunity to look at factors of Zika on brain development,” says William D. Gaillard, M.D., division chief of both Epilepsy and Neurophysiology, and Neurology at Children’s National. “This is a very competitive award. It’s a tremendous achievement that few accomplish.”

Children’s National is the leading site for this international research study.

In 2015, Dr. Kousa established the Zika Genetic Consortium to investigate whether maternal and fetal genetic factors can modify the risk of brain injury from congenital infections. Dr. Kousa is the principal investigator of the consortium, which includes 19 co-investigators representing 13 different institutions.

The consortium is bringing together cohorts of 12,000 mother-infant participants retrospectively and prospectively. These cohorts come from 15 international health centers in seven countries in collaboration with partners at the National Institutes of Health, and the Centers for Disease Control and Prevention.

“This support gives us the opportunity to test our hypothesis,” says Dr. Kousa. “We also hope what we continue to learn about Zika can play a role in helping us understand other congenital infections and neurodevelopment diseases.”

Doctors at Children’s National give Jake his life back

/in , /by
Jake and Dr. Oluigbo

At the age of 17, Jake underwent surgery led by neurosurgeon Chima Oluigbo, M.D., where he conducted a temporal lobe resection, also called temporal lobectomy, that works to lower the number of seizures, make them less severe or stop them completely. The surgery ended up being successful and it worked to greatly improve his overall quality of life.

Since 1969, November has been considered Epilepsy Awareness Month to highlight the importance of recognizing a seizure and promoting seizure first aid. At Children’s National Hospital, doctors in the division of neurology are committed to finding treatments for epilepsy and have done just that by helping Jacob Yates, an 18-year-old patient, get his life back.

For many families the holidays are meant for spending time with loved ones and enjoying the seasonal festivities. However, the holidays were not always a joyous occasion for Jake and his family. Since he was a baby, many of his holidays were spent in a bed due to a brain disorder that caused him to have developmental delays and, at times, up to 17 seizures a day.

“The holidays were always a tough time for the family because Jake would get so excited around Christmas that it would overwhelm his system and induce seizures that took him days to recover from,” says his mom, Jennifer.

Jake was born a preemie and hours after he was born, doctors at his local hospital had identified that he was having trouble breathing. By coincidence, the Children’s National transport team was on-site to take another patient to Children’s National, but once they looked at Jake they immediately took him instead by SkyBear Air Transport, the hospital’s rapid helicopter transport service.

During his stay at Children’s National, Jake was in the neonatal intensive care unit (NICU) for 11 days and was supported by breathing machines to help with respiratory distress and other issues stemming from him being born prematurely.

“If it wasn’t for the Children’s National transport team coincidentally being at our local hospital, Jake wouldn’t have survived staying at that location,” said Jennifer.

After he was taken care of at Children’s National, he was discharged 11 days later, but at the age of three months Jake was still experiencing respiratory issues and was taken back to his local hospital in Charles County.

“When he first arrived back at the University of Maryland Charles Regional Medical Center, the doctors thought he may have had cystic fibrosis, but it came back that perhaps he was suffering from reflux and they put him on medication,” Jennifer recalls. Unfortunately, this was not the cause and it would not be the family’s last visit to the hospital.

By the age of six months, Jake had his first seizure and he was flown back to Children’s National. Over the next year he was repeatedly admitted to the hospital as his seizures had caused him to stop breathing.

Between the ages of 4 to 6 years old, Jake became a patient of William D. Gaillard, M.D., division chief of epilepsy and neurophysiology and Roger Packer, M.D., senior vice president at the Center of Neuroscience and Behavioral Health at Children’s National. After his visit, both doctors recommended surgery, but Dr. Packer recommended that Jake receive an electroencephalogram (EEG), magnetic resonance imaging (MRI) and go through a sleep study first to identify the specific causes of his seizures.

Now on a new medication, his seizures were maintained for the most part, but doctors were still recommending that it was time for surgery. When Jake was 15, his parents re-evaluated the surgery and learned that their son had a 76% chance of being seizure and medication free.

At the age of 17, Jake underwent surgery led by Chima Oluigbo, M.D., neurosurgeon at Children’s National, where he conducted a temporal lobe resection, also called temporal lobectomy, that works to lower the number of seizures, make them less severe or stop them completely. The surgery ended up being successful and it worked to greatly improve his overall quality of life.

Before the surgery, Jake didn’t speak much, experienced anxiety and had difficulty expressing his emotions. He had never told his mother that he loved her. After the surgery, Jake looked at his mother and said, “I love you babe.”

According to Jennifer, since the surgery her son is a completely different person and states that he has been seizure free for over a year. Equally, Jake and the family can now all look forward to the holidays.

“We’re so excited to have him share the holidays,” Jennifer says. “He feels better and it shows through his attitude and the way he responds to things. Words can’t express the gratitude we have for the doctors at Children’s National Hospital. They gave my son his life back.”

Putting childhood epilepsy in the spotlight at American Epilepsy Society Meeting

“We aim to build the evidence base for treatments that are effective specifically for children with epilepsy,” says William D. Gaillard, M.D., chief of Child Neurology, Epilepsy and Neurophysiology, and director of the Comprehensive Pediatric Epilepsy Program.

While epilepsy affects people of all ages, the unique way it manifests in infants, children and adolescents can be attributed in part to the complexities of the growing and developing brain. Researchers from the Children’s National Comprehensive Pediatric Epilepsy Program brought their expertise on the challenges of understanding and treating epilepsy in children to the recent American Epilepsy Society Annual Meeting, the largest professional gathering on epilepsy in the world.

“We aim to build the evidence base for treatments that are effective specifically for children with epilepsy,” says William D. Gaillard, M.D., chief of Child Neurology, Epilepsy and Neurophysiology, and director of the Comprehensive Pediatric Epilepsy Program. “We have learned much from studies in adult populations but technologies like functional MRI allow us to get in-depth understanding, often in non-invasive ways, of precisely how epilepsy is impacting a child.”

Dr. Gaillard was also recently elected to serve as the Second Vice President of the American Epilepsy Society. “The AES is the largest multidisciplinary professional and scientific society dedicated to the understanding, treatment and eradication of epilepsy and associated disorders, and I am honored to serve as the new Second Vice President,” he said.

The team’s presentations and poster sessions focused on several key areas in pediatric epilepsy:

Better ways to see, measure and quantify activity and changes in the brain for children with epilepsy before, during and after surgery

  • Novel applications of fMRI for children with epilepsy
    • Evaluation of an fMRI tool that tracks verbal and visual memory in children with epilepsy – one of the first to capture memory functions in this population of children using noninvasive fMRI;
    • Early study of the use of “resting-state” fMRI to map language skills before epilepsy surgery – an important first step toward noninvasively evaluating children who are too young or neurologically impaired to follow tasks in traditional MRI studies;
  • A study of whether intraoperative MRI, i.e. imaging during neurosurgery, allows for more complete removal of abnormal brain tissue associated with focal cortical dysplasia in children, which is a common cause of intractable epilepsy;
  • A preliminary case review of existing data to see if arterial spin labeling MRI, which measures blood flow to the brain, has potential to identify blood flow changes in specific locations of the brain where seizures occur;
  • An analysis of language laterality – the dominant side of the brain controlling language –  questioning the true reasons that the brains of children with epilepsy have differences in the hemisphere that predominantly controls language;
  • A review of some common assessments of language and working memory that are used pre- and post-operatively to gauge the impacts of pediatric epilepsy surgery. The study found that using multiple assessments, and studying results individually rather than as a group average, resulted in a more complete picture of the outcomes of surgery on these areas of brain function;
  • A preliminary study examining whether continuous EEG monitoring of neonates with hypoxic ischemic encephalopathy, or lack of oxygen to the brain, can be a reliable predictor of neurodevelopmental outcomes while the infant is undergoing therapeutic hypothermia.

“In order to expand our understanding of causes, impacts and outcomes, the range of research is broad given the complexity of epilepsy,” says Madison M. Berl, Ph.D. “This is the only way we can contribute to the goal of providing our colleagues and the families they serve with better resources to make informed decisions about how best to assess and treat pediatric epilepsy.”

The molecular, genetic and biological factors that contribute to onset and severity of pediatric epilepsy

  • A retrospective study of young patients with malformations in cortical development that are important causes of childhood epilepsy;
  • Investigation of a simple saliva test to effectively identify the presence of two common viral infections, human herpesvirus-6B and Epstein-Barr virus, that may be contributors to onset of epilepsy in otherwise normally functioning brains;
  • A preliminary review of the possible relationship between febrile infection-related epilepsy syndrome and the co-occurrence of another neuro-inflammatory condition – hemophagocytic lymphohistiocytosis.

Madison Berl, Ph.D., director of research in the Division of Pediatric Neuropsychology, and a pediatric neuropsychologist in the Comprehensive Pediatric Epilepsy Program, adds, “In order to expand our understanding of causes, impacts and outcomes, the range of research is broad given the complexity of epilepsy. This is the only way we can contribute to the goal of providing our colleagues and the families they serve with better resources to make informed decisions about how best to assess and treat pediatric epilepsy.”

In late June, a delegation of international pediatric experts from Children’s National Health System journeyed across the world to learn about the practice of pediatric medicine in China and to exchange ideas with colleagues there. Leaders from several of Children’s key specialties joined the delegation, including:

The group, led by Drs. Keating and Gaillard, traveled to China with Children’s Outreach Coordinator John Walsh, whose longtime connections and close familiarity with the pediatric medical community in Hangzhou and Shanghai made the collaboration possible. The team toured several of the largest children’s hospitals in country, including The Children’s Hospital of Zhejiang University School of Medicine in Hangzhou and Shanghai Children’s Medical Center, connecting with pediatric specialists there.

“Some of the most important parts of this trip were the opportunities to exchange ideas and solidify long term relationships that will allow us to work closely with our peers in China as they develop their pediatric programs. The potential is tremendous for unique collaborations between our teams and theirs for research and the development of clinical care improvements for children,” said Roger Packer, M.D., senior vice president of the Center for Neuroscience and Behavioral Medicine, who joined the delegation in Beijing.

A keynote lecture and more at the 3rd China International Forum on Pediatric Development

The delegation also was honored with an invitation to participate in the 3rd China International Forum on Pediatric Development. The forum is one of the largest pediatric focused meetings in the country and is led by all the major children’s hospitals in China, including those in Beijing and Shanghai. Close to 4,000 pediatricians attended the meeting, and presenters included esteemed international leaders in pediatric medicine from around the world.

Dr. Packer delivered one of the opening keynote lectures, entitled, “Translation of molecular advances into care: the challenge ahead for children’s hospitals.” His talk focused on the tremendous promise and significant challenges posed by the latest scientific advances, through the lens of a neurologist.

“Across the world, we are looking at the same challenges: How can we use scientific advances to find better outcomes? How can we financially support the new types of interventions made possible by these molecular biologics insights when they can cost millions of dollars for one patient?”

“There’s palpable excitement that these new developments will give us potential therapies we never dreamed about before, ways to reverse what we initially thought was irreversible brain damage, ways to prevent severe illnesses including brain tumors, but the issue is how to turn this promise into reality. That’s a worldwide issue, not simply a single country’s issue,” he continued.

He also flagged mental health and behavioral health as a crucial, universal challenge in need of addressing on both sides of the Pacific.

The Children’s National delegation, including Drs. DeBiasi, Song, Keating, Gaillard and Packer were also honored to share their insight in a series of specialty-specific breakout sessions at the Forum.

Overall, the long journey opened a dialogue between Children’s National and pediatric care providers in China, paving the way for future discussion about how to learn from each other and collaborate to enhance all institutions involved.

Surprising consensus on pediatric anti-epilepsy meds

/in , /by

A study that includes William D. Gaillard, M.D., among its authors indicates that U.S. doctors appear to have reached an unexpected consensus about which anti-seizure medicine to prescribe to their pediatric patients.

The number of available anti-seizure medications has exploded in the past two decades, going from just a handful of medicines available in the 1990s to more than 20 now. Once the Food and Drug Administration (FDA) approves each new medicine based on trials in adults, it’s available for clinicians to prescribe off-label to all age groups. However, says William D. Gaillard, M.D., division chief of Child Neurology and Epilepsy, Neurophysiology and Critical Care Neurology at Children’s National Health System, trials that lead to FDA approval for adults do not provide any information about which medications are best for children.

“With so many medications and so little data,” Dr. Gaillard says, “one might think doctors would choose a wider variety of medicines when they prescribe to children with epilepsy.”

However, the results from a recent study that included Dr. Gaillard and colleagues, published online in Pediatric Neurology on June 27, 2017, show otherwise. The study indicates that doctors in the United States appear to have reached an unexpected consensus about which medication to prescribe for their pediatric patients.

The study is part of a broader effort to collect data on the youngest epilepsy patients – those younger than 3 years old, the age at which epilepsy most often becomes evident. As part of this endeavor, researchers from 17 U.S. pediatric epilepsy centers enrolled in the study 495 children younger than 36 months old who had been newly diagnosed with non-syndromic epilepsy (a condition not linked to any of the commonly recognized genetic epilepsy syndromes).

The researchers mined these patients’ electronic medical records for information about their demographics, disease and treatments. About half of the study participants were younger than 1 year old when they were diagnosed with epilepsy. About half had disease marked by focal features, meaning that their epilepsy appeared to originate from a particular place in the brain. Nearly all were treated with a single medication, as opposed to a cocktail of multiple medicines.

William Gaillard

“This study identifies current practices, but whether those practices are correct is a separate question,” explains Dr. Gaillard. “Just because a medication is used commonly doesn’t mean it is the best medication we should be using.”

Of those treated with a single medication, nearly all were treated with one of five medicines: Levetiracetam, oxcarbazepine, phenobarbital, topiramate and zonisamide. However, the data showed a clear prescribing preference. About 63 percent of the patients were prescribed levetiracetam as a first choice. By contrast, oxcarbazepine and phenobarbital, the next most frequently prescribed medicines, were taken by patients as a first choice by a mere 14 percent and 13 percent respectively.

Even more striking, of the children who were not prescribed levetiracetam initially but required a second medication due to inadequate efficacy or unacceptable side effects, 62 percent also received this medication. That made levetiracetam the first or second choice for about 74 percent of all the children in the study, despite the availability of more than 20 anti-seizure medications.

It’s not clear why levetiracetam is such a frequent choice in the United States, says Dr. Gaillard. However, in its favor, the drug is available in a liquid formulation, causes no ill effects medically and can be started intravenously if necessary. Studies have shown that it appears to be effective in controlling seizures in about 40 percent of infants.

Yet, levetiracetam’s market dominance appears to be a North American phenomenon, the study authors write. A recent international survey that Dr. Gaillard also participated in suggests that outside of this continent, carbazepine and oxcarbazepine were the most frequently prescribed medications to treat focal seizures.

What’s really necessary, Dr. Gaillard says, is real data on efficacy for each of the medications commonly prescribed to pediatric epilepsy patients – a marked vacuum in research that prevents doctors from using evidence-based reasoning when making medication choices.

“This study identifies current practices, but whether those practices are correct is a separate question,” he explains. “Just because a medication is used commonly doesn’t mean it is the best medication we should be using.”

To answer that question, he says, researchers will need to perform a head-to-head clinical trial comparing the top available epilepsy medications in children. This study sets the stage for such a trial by identifying which medications should be included.

“Uncontrolled pediatric epilepsy can have serious consequences, from potential problems in development to a higher risk of death,” Dr. Gaillard says. “You want to use the optimal medicine to treat the disease.”

Working miracles to control seizures and preserve brain power in newborns

/in , , , , , /by
Oluigbo and Myseros neurosurgery

In the spring of 2017, a multidisciplinary team applied an innovative approach to help preserve function in the working right hemisphere of a baby who experienced her first seizure hours after birth.

When orderly early fetal brain development is disturbed in one half of the brain, infants can be born with hemimegalencephaly—a rare occurrence—that results in one of the brain’s two hemispheres being oversized, heavy and malformed. This brain malformation arises early in the fetal period of life, is not inherited and is associated with seizures early in life.

Children with hemimegalencephaly can develop horrible seizures within the first hours or days of life. According to published research, every month these infants experience uncontrolled seizures correlates to a steep decline in IQ.

Because these types of seizures do not respond to multiple anti-seizure medications—medicines which may also cause worrisome side effects of their own in neonates—care teams attempt to schedule surgery as soon as feasible to remove or disconnect the hemisphere triggering the damaging seizures. “The ‘bad’ brain does not sustain any function and it interferes with the ‘good’ brain doing what it needs to do,” says William D. Gaillard, M.D., chief of Children’s division of Epilepsy and Neurophysiology and chief of Neurology.

Hemispherectomy is intricate surgery on an organ that is softer than normal and crisscrossed with a tangle of blood vessels that supply the damaged hemisphere with blood. Because of the risks of life-threatening blood loss in very young infants, the dramatic surgery is usually not performed until babies are at least 3 months old and weigh at least 10 pounds.

The challenge: The vulnerable babies who most need relief, infants who have been seizing since early life, are too young for the operation.

Neurosurgeons have clamped the carotid artery that supplies blood to the brain to minimize blood loss when the hemisphere is surgically removed. Dr. Gaillard says knowledge of that approach led the team to think: What if we use embolization—blocking blood supply to targeted locations in the brain—to achieve the same effect?  The plan effectively destroys the malformed brain from within, neutralizing its ability to cause the seizures.

“It was eye-opening for us to think about actually inflicting brain injury as a way of treating something in the brain that was causing seizures. That is really novel in itself: We’re thinking out of the box in applying existing techniques in a different age group. The conventional thinking with newborns is to let them be; their seizures don’t look that bad,” says Taeun Chang, M.D., director of Children’s Neonatal Neurology and Neonatal Neurocritical Care Program.

“We have evidence to suggest this is a safe and effective way of avoiding recurrent seizures and minimizing the need to give these infants potentially toxic medications so early in life. Ultimately, this helps a select group of babies who need the surgery to get to the point of being old enough to have it—all the while, sparing the healthy part of their brain,” Dr. Gaillard adds.

Darcy hemimegalencephaly

Once the embolization ended Darcy’s most severe seizures, the little girl could make eye contact, started smiling, and then graduated from smiling to full laughs. In weekly physical therapy, the infant works on tummy time, head control and ensuring her eyes track.

In the spring of 2017, the multidisciplinary team applied the innovative approach to help preserve function in the working right hemisphere of a baby named Darcy Murphy. Darcy experienced her first seizure hours after she was born, and when she arrived at Children’s National had been in and out of two different emergency rooms in another state for the first few weeks of her life.

The team explained to the Murphy family that Darcy was on multiple medications, but her seizures continued unabated. The options included inducing a coma, sending Darcy home despite ongoing seizures or minimally invasive embolization.

“We would not have even posed this if we were not confident in our ability to do the procedure and deal with potential complications,” Dr. Chang says.

“Oh my gosh, as a parent you know what you’re doing is permanent,” says Rachel Murphy, 29, Darcy’s mom said of the decisions that she and husband Ryan, 33, faced for the youngest of their three children. “What if it’s not the right decision? What if in a week they come out with a new procedure you could have done? We were horrified all the time. The nice part with this procedure is the reward is apparent very quickly, and it just gets better. You don’t have to wait two years to know you made the right decision. You can see half a brain is better than the whole thing for this specific child.”

Once the embolization ended Darcy’s most severe seizures, the little girl could initiate and maintain eye contact with family members, started smiling and then graduated from smiling to full laughs. In weekly physical therapy, the infant works on tummy time, head control and ensuring her eyes track.

Children’s multidisciplinary care team includes experts in newborn intensive care (neonatologists) to aggressively manage seizures in the traditional fashion as they occur and to monitor vital signs; a neonatal neurologist/neurointensivist at the bedside and in the Angio suite monitoring Darcy’s brain activity; a neonatal epileptologist; a surgical epilepsy team; an interventional neuroradiologist; neurosurgeons to perform the delicate functional hemispherectomy to remove any residual brain tissue from the bad hemisphere; and physical therapists working to help Darcy achieve maximum function after surgery.

“We were just like one unit in the sense of being able to provide coherent, comprehensive care. It’s about blood pressure management, breathing, electrolytes, making sure everything is right for going to the operating room,” Dr. Chang explains. “Darcy’s case highlights the ways in which Children’s National is different and offers personalized care that is superior to other centers.”

The team, which recently published a case report of two previous serial embolizations followed by hemispherectomy, plans follow-up papers describing EEG manifestations during an acute stroke in a newborn, advice to the field on best practices for the embolization and using cooling to control the planned brain injury during embolization hemispherectomy.

Expanding awareness of SUDEP

/in , , , /by
Madison Berl

Madison M. Berl, Ph.D., is helping to expand awareness of SUDEP among patients, families and caregivers.

When 4-year-old Henry Lapham died in his sleep just weeks after being diagnosed with epilepsy in 2009, it was a shock to everyone — even his pediatrician and neurologist. Henry’s cause of death was sudden unexpected (or unexplained) death in epilepsy persons (SUDEP), a condition that causes sudden death in about 1 of every 1,000 otherwise healthy patients with epilepsy. Neither health care professional had mentioned this as a possibility, as remote as it was.

“I was desperate to make sense out of our tragedy,” writes Henry’s mother, Gardiner Lapham, R.N., M.P.H., in “Increasing awareness of sudden death in pediatric epilepsy together,” an article published in the February 2017 issue of Pediatrics. After her son’s death, by working with a group called Citizens United for Epilepsy Research, Lapham connected with other families affected by the same heartbreak. “I have met many bereaved family members,” she adds, “and the most consistent thing I hear is that they wish they had known about SUDEP.”

Now, a new collaboration with Children’s National Health System, where Henry received care, University of Virginia Medical Center (UVA) and other academic medical centers is helping to expand awareness of SUDEP among patients, families and caregivers alike. Known as Childhood Epilepsy Risks and Impact on Outcomes (CHERIO), the multiyear effort aims to develop approaches to increase knowledge about SUDEP and other conditions that can accompany epilepsy, such as attention deficit hyperactivity disorder, autism, anxiety, depression and sleep issues, according to co-authors of the Pediatrics article.

CHERIO got its start in 2014 at the American Epilepsy Society annual meeting. There, Lapham met Madison M. Berl, Ph.D., director of research, Division of Pediatric Neuropsychology at Children’s National, who studies epilepsy comorbidities. When Lapham asked what she could do to help raise awareness of SUDEP at Children’s National, she and Berl, along with William Davis Gaillard, M.D., Henry’s neurologist, hatched a plan.

Working with multiple disciplines and stakeholders, including neuropsychologists, psychiatrists, neurologists, epidemiologists, basic scientists, nurses and parent advocates at both Children’s National and UVA, CHERIO plans to assess the level of knowledge about SUDEP and other epilepsy comorbidities among medical providers and parents and to implement ways to increase knowledge. The first item on the agenda, Berl explains, was to conduct a survey to see just how much doctors knew about SUDEP.

“Although many neurologists are aware of this condition, ours was the first to survey pediatricians, and the majority was not aware of SUDEP – despite having children with epilepsy in their practice,” Dr. Gaillard says. “We know that many neurologists do not discuss SUDEP with patients and the reasons for not talking about SUDEP are varied. Thus, CHERIO felt that in addition to educating neurologists about the need to discuss the risk of death associated with epilepsy, increasing pediatricians’ awareness of SUDEP is one approach that could open more opportunities for families to have this discussion.”

To help make it easier to talk about this risk, the CHERIO team is developing strategies for doctors to start the conversation with patients and their families by framing SUDEP in the context of more common epilepsy comorbidities.

“Clinicians walk a fine line in giving information at the right time to make people more aware,” Berl adds, “but also being realistic and giving information that fits with what’s going on in a particular child’s case. By discussing SUDEP along with other, more common epilepsy risks, it brings context to a family so that they’re not unduly concerned about death – which also can paralyze a family and create unnecessary alarm.” The risk of death in most children with epilepsy is very low, slightly higher than the risks faced by healthy children. But parents of children with complicated epilepsy who have more risk factors for sudden death should be especially aware , she says.

Another way to help facilitate discussion may be through a simple tweak in the medical record, Berl adds. The team is currently developing a checklist that pops up annually in a patient’s medical record to remind clinicians of important points to discuss with patients and their families, including SUDEP.

Additionally, they are working on ways that can help families become more empowered to start the discussion themselves. Materials for the waiting room or questionnaires to fill out before appointments could trigger conversations with care providers, Berl says.

Last, the team also is collaborating with a medical device company that is working on a nighttime monitoring system that could provide an alert if patients with epilepsy experience nighttime seizures, a risk factor for SUDEP. Such technologies have not been proven to prevent SUDEP. Yet, it may help caregivers get help more quickly than if they did not receive the alert.

For each of these efforts, Berl notes, having Lapham as a partner has been key. “She’s part of our meetings and has input into the direction of each project,” Berl explains. “When you have a partner who is so close to the daily work you’re doing, it just heightens those efforts and brings to the forefront the simple message of why this is important.”

Using fMRI for assessment prior to neurosurgery

/in , , , /by

For more than 20 years, Children’s National has explored the use of non-invasive fMRI as an alternative to more invasive testing to assess children’s language and memory.

A new Practice Guideline Summary published in Neurology, the journal of the American Academy of Neurology, contains the first complete, objective assessment of available data on the efficacy of functional magnetic resonance imaging (fMRI) to assess baseline language and memory, brain hemisphere dominance and to predict postsurgical impacts prior to surgery in patients with epilepsy.

According to contributing author William D. Gaillard, M.D., chief of Child Neurology, Epilepsy and Neurophysiology, and director of the Comprehensive Pediatric Epilepsy Program at Children’s National Health System, the report outlines several cases in which fMRI presents an effective alternative to the current standard of care, intracarotid amobarbital procedure (IAP). In IAP, medication is injected through the carotid artery to isolate one hemisphere of the brain at a time, followed by the patient performing memory or language tasks. The approach requires catheterization via a major artery. While minimally invasive, the procedure still carries the standard risks of vascular catheter procedures and requires recovery time.

“This publication took six years to complete,” Dr. Gaillard notes, “but we are happy to finally have the practice parameters that will make the case for the use of fMRI in an evidence-based way.”

Though the Practice Guidelines focus on adults, the evidence assessment included all available pediatric data as well, says Dr. Gaillard. A great deal of that data were contributed by Children’s National faculty, who lead the nation in clinical applications of fMRI. More than 20 years ago, Dr. Gaillard and his team began studying fMRI as a viable alternative to IAP to collect accurate language assessments in children, particularly those with epilepsy. Today, Children’s National is at the forefront of clinical application of fMRI, having performed about 1,000 pediatric assessments in the last two decades — more than nearly every other institution.

An 11-member panel of international experts conducted the analyses for the Practice Guidelines. Overall, the report indicates:

  • fMRI is a viable option for measuring lateralized language functions in place of IAP in medial temporal lobe epilepsy, temporal epilepsy in general or extratemporal epilepsy.
  • Evidence was insufficient to recommend fMRI over IAP for patients with temporal neocortical epilepsy or temporal tumors.
  • Pre-surgical fMRI can serve as an adequate alternative to IAP memory testing for predicting verbal memory outcome.

In closing, the authors also explicitly recommend that clinicians carefully advise every patient of the risks and benefits of both fMRI and IAP before recommending either approach.

What’s Known

Neurologists assess a patient’s baseline language and memory, and attempt to predict postsurgical impacts on language before the patient undergoes neurosurgical procedures to minimize the symptoms of epilepsy. In a standard intracarotid amobarbital procedure (IAP), a medication is injected through the carotid artery that isolates one hemisphere of the brain at a time followed by the patient performing memory tasks. More recently, neurologists have performed the assessment via functional magnetic resonance imaging (fMRI), an image acquisition technique that captures brain activity while the patient completes a set of memory and language tasks. Both approaches lack standardized implementation guidelines, making it difficult to fully assess when fMRI may be an effective alternative to IAP.

What’s New

A Practice Guideline Summary published in Neurology, the journal of the American Academy of Neurology, regarding the use of fMRI for pre-surgical evaluation of patients with epilepsy establishes recommendations related to the diagnostic accuracy of fMRI for pre-surgical evaluation. An 11-member panel of international experts, including William D. Gaillard, M.D., Chief of Child Neurology, Epilepsy and Neurophysiology, and Director of the Comprehensive Pediatric Epilepsy Program at Children’s National Health System, evaluated available evidence to determine when and if fMRI can reliably measure the extent that each brain hemisphere controls language, known as language lateralization, and as a predictor of postsurgical outcomes. For 20 years, Dr. Gaillard’s team has led the field in the application of fMRI for language and memory assessment in children, and their work comprised a large portion of the pediatric-focused research assessed by the panel. The analyses found that fMRI is a viable option for measuring lateralized language functions in place of IAP in medial temporal lobe epilepsy, temporal epilepsy in general or extratemporal epilepsy. Evidence was insufficient to recommend fMRI over IAP for patients with temporal neocortical epilepsy or temporal tumors. The assessment also identified that pre-surgical fMRI can serve as an adequate alternative to IAP memory testing for predicting verbal memory outcome. The authors recommend that clinicians carefully advise patients of the risks and benefits before recommending either approach.
