Children’s National performs first ever HIFU procedure on patient with cerebral palsy

February 9, 2024

HIFU is a non-invasive therapy that utilizes focused ultrasound waves to thermally ablate a focal area of tissue.

In January, a team of multidisciplinary doctors performed the first case in the world of using bilateral high intensity focused ultrasound (HIFU) pallidotomy on Jesus, a 22-year-old patient with dyskinetic cerebral palsy.

The procedure is part of a clinical trial led by Chima Oluigbo, M.D., pediatric neurosurgeon at Children’s National Hospital.

“The primary objective of the study is to evaluate the safety of ExAblate Transcranial MRgFUS as a tool for creating bilateral or unilateral lesions in the globus pallidus (GPi) in patients with treatment-refractory secondary dystonia due to dyskinetic cerebral palsy,” Dr. Oluigbo explained. “The secondary purpose is to assess the impact of HIFU pallidotomy on dyskinetic cerebral palsy movement disorder in pediatric and young adult patients.”

In addition, the impact of bilateral pallidotomy on motor development, pain perception, speech, memory, attention and cognition in these patients will be assessed.

“We hope that the trial will help us find results that lead to treatments that can reduce the rigidity and stiffness which occurs in cerebral palsy so we can help these children who do not have any effective treatment,” Dr. Oluigbo added.

“This new, first of its kind, non-invasive therapeutic approach – without even a skin incision – will open the door to offering hope for a number of kids with movement disorders who have failed conventional therapy,” said Robert Keating, M.D., chief of neurosurgery at Children’s National. “We are at the beginning of a new era for treating functional disorders in the pediatric patient.”

How it works

HIFU is a non-invasive therapy that utilizes focused ultrasound waves to thermally ablate a focal area of tissue. In the past, Children’s National successfully used HIFU to treat low-grade type tumors located in difficult locations of the brain, such as hypothalamic hamartomas and pilocytic astrocytoma, as well as for epilepsy and other movement disorders.

This most recent procedure was another successful milestone for the hospital, discharging Jesus the following day without any complications.

The team comprised neurosurgeons, MRI techs, anesthesiologists and radiologists, to name a few.

Originally, Jesus came to Children’s National in 2006 when he started working with the Physical Medicine and Rehabilitation team to help him with his muscle hypertonia management as well as equipment, orthoses and therapy concerns.

“As he continued to grow, his muscle hypertonia became more pronounced and caused difficulty with his care, positioning and comfort,” said Olga Morozova, M.D., pediatric rehabilitation specialist at Children’s National. “We have tried multiple oral medications however he has had significant side effects from the majority of the medications.”

Dr. Morozova and Julie Will, M.S.N., F.N.P., the nurse practitioner that worked with Jesus, referred him to Dr. Oluigbo after they learned about HIFU being an option to treat Jesus using a non-invasive approach.

Moving the field forward

This clinical trial highlights the expanding indications for focused ultrasound.

“We are excited about the potential for these innovative treatment strategies in neurosurgery to transform the lives of pediatric patients who suffer from challenging diseases, such as brain tumors, epilepsy, and movement disorders,” said Hasan Syed, M.D., co-director of the Focused Ultrasound Program at Children’s National. “We are redefining what is possible in neurosurgery.”

From low-intensity focused ultrasound (LIFU) treatments for our young DIPG patients to now the groundbreaking research on HIFU for pediatric movement disorders, the dedication to cutting-edge techniques highlights the team’s commitment to patients and transforming pediatric neurosurgical care.

Novel camera + machine learning = hope for more precise neurosurgery

October 27, 2023

collage of hyperspectral imaging (sHSI) camera and brain surgery

Researchers at Children’s National Hospital developed a compact imaging camera capable of seeing beyond the human visual spectrum to help segment healthy brain tissue from tumors during surgery. The groundbreaking technology will allow neurosurgeons to make more precise, real-time decisions in the operating room, rather than sending samples to pathology labs for biopsies.

In a manuscript published in Bioengineering, the team of engineers and neurosurgeons details how its snapshot hyperspectral imaging (sHSI) camera can be used to capture and process images of brain tissue, using the wide spectrum of light between visible and infrared wavelengths. That additional information — beyond the human eye — has the potential to allow for more accurate and complete tumor removal.

“In the hands of a neurosurgeon, this camera, when combined with machine learning, could dramatically improve outcomes for some of our most vulnerable brain tumor patients,” said Richard Jaepyeong Cha, Ph.D., an optical engineer and principal investigator at the Sheikh Zayed Institute of Pediatric Surgical Innovation. “We are able to attach the camera to a surgical microscope and process a significant amount of information from the patient while in the operating room. Not only could this lead to more complete tumor resection, it will also allow the surgeon to save as much healthy brain tissue as possible and reduce lifelong neurological complications.”

Why we’re excited

Brain tumors are the most common solid tumors in children, accounting for the highest number of pediatric cancer deaths globally each year. To develop a treatment plan, neurosurgeons need to understand the tumor’s features, including its type, grade of malignancy, location and its categorization as a primary or metastatic cancer. This information leads to decisions about how to remove or biopsy a tumor.

Under the current protocols, surgeons evaluate tumor margins in the operating room by examining the appearance of the brain tissue and sending out small samples to the pathology department for biopsies. This can lead to longer surgeries and difficult real-time surgical decisions. For instance, some low-grade tumors are visually indistinguishable from healthy brain tissue.

In four investigational cases approved by the hospital’s institutional research board, the sHSI camera was used in the operating room to help segment healthy pediatric brain tissue from tumors. Unlike the conventional red-green-blue (RGB) imaging cameras, which use only those three colors, HSI captures spectral data at each pixel of the image — a task too complex for the human eye — and sends it instantly for processing by an algorithm designed to assist in tumor segmentation.

What’s ahead

Despite the small dataset, the researchers were able to successfully segment healthy brain tissue from lesions with a high specificity during pediatric brain tumor resection procedures. Significant work remains to refine the technology and the machine learning behind it. Researchers also plan to integrate the sHSI camera into a laparoscope to visualize tumors that are not on the brain’s surface and collect data from more angles.

“As we develop these groundbreaking tools, we plan to continue to expand the dataset and refine the algorithm to make pediatric neurosurgery continually more precise,” said Naomi Kifle, M.S., research and development engineer at Children’s National and first author on the paper. “As our dataset grows, we hope to create a model that can distinguish healthy brain tissue, tumor and skull. This groundbreaking surgical tool shows significant promise.”

growth of the Children's National Spina Bifida Program

A look at the Children’s National Spina Bifida Program

December 19, 2022

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.

Children’s National uses HIFU to perform first ever non-invasive brain tumor procedure

February 9, 2022

Children’s National Hospital successfully performed the first-ever high-intensity focused ultrasound (HIFU) procedure on a pediatric patient with neurofibromatosis (NF). This is the youngest patient to undergo HIFU treatment in the world. Image provided by Insightec.

Children’s National Hospital successfully performed the first-ever high-intensity focused ultrasound (HIFU) procedure on a pediatric patient with neurofibromatosis (NF). This is the youngest patient to undergo HIFU treatment in the world. The advancement of children’s medical devices in the U.S. continues to significantly lag behind adult devices. This is why this milestone marks a significant advance in making pediatric surgery more precise and less invasive.

The hospital is offering this treatment to patients under an ongoing research clinical trial. Children’s National is one of the first pediatric hospitals in the nation to use HIFU for neuro-oncology patients. It’s also the first hospital in the world to use it to treat a pediatric patient with NF. NF is a condition that occurs in approximately 1 in 3,500 births and causes tumors to form in the brain, spinal cord and nerves.

“Using HIFU to treat our pediatric patients is a quantum leap towards non-invasive surgery for kids,” said Robert Keating, M.D., division chief of Neurosurgery and co-director of the HIFU program at Children’s National. “It’s exciting because the future is now here and it’s significantly better for our kids, in terms of non-invasive surgery with lower risk of complications and no exposure to radiation.”

Focused ultrasound (FUS) is a non-invasive therapeutic technology with the potential to transform the treatment of many medical disorders by using ultrasonic thermal energy to specifically target tissue deep in the body. The technology can treat without incisions or the need of radiation.

FUS, which has been used for adult clinical trials for many decades, can be delivered through high- or low-intensity focused ultrasound (LIFU). HIFU uses non-invasive therapy that uses focused ultrasound waves to thermally ablate a focal area of tissue. Children’s National will now use HIFU to treat low-grade type tumors located in difficult locations of the brain, such as hypothalamic hamartomas and pilocytic astrocytoma, as well as for movement disorders and epilepsy.

An alternative approach, LIFU uses lower levels of energy to disrupt the blood-brain barrier. Unlike medications, which often have difficulty crossing the blood-brain barrier, LIFU can transiently open the blood-brain barrier to chemotherapy. This may allow more effective treatment of tumors and offer opportunities to treat, for the first time, the entire extent of a malignant brain tumor.

“Having focused ultrasound technology as a tool and conducting clinical trials will allow our neurologists and oncologists to offer a non-invasive treatment option to many patients who suffer from neurological conditions,” said Hasan Syed, M.D., co-director of the HIFU program at Children’s National. “The milestone of performing this first HIFU procedure will lead the way to better understanding of the effect of this technology and provide patients with more options.”

At Children’s National, the HIFU program is being led by Dr. Keating and a multidisciplinary team, including clinicians and investigators from the Sheik Zayed Institute for Pediatric Innovation, radiology, oncology, surgery and orthopedics. In an effort to collaborate with the region’s adult hospitals, Children’s National will also treat adult patients on a selective basis who have movement disorders such as essential tremor and Parkinson’s. There is a scarcity of similar resources in the metro region. Many adult patients face one-year wait periods for treatment of their movement disorders, requiring many to travel out of state for treatment.

The LIFU program is scheduled to be operational in 2022. It will likely be the first in the U.S. to treat high-grade pediatric brain tumors with disruption of the blood-brain barrier and provide more effective routes for chemotherapy as well as potential immunotherapy and molecular approaches.

“The use of LIFU with microbubbles to open up the blood-brain barrier is an exciting, potentially game-changing approach for children with these tumors,” said Roger Packer, M.D., senior vice president of the Center for Neurosciences and Behavioral Medicine at Children’s National. “It should safely allow the blood-brain barrier to open and allow delivery of potentially life-saving personalized therapy to the tumor and spare the rest of the brain. It is the most exciting, new development in brain tumor therapy for these malignant midline tumors in the past 50 years.”

Children’s National continues to be a leader in pediatric HIFU use. In 2015, Children’s National doctors became the first in the U.S. to use MR-HIFU to treat pediatric osteoid osteoma – a benign, but painful bone tumor. Successful clinical trial results led to FDA approval in early 2021 for the use of the technology for this treatment. In 2020, the Focused Ultrasound Foundation also designated Children’s National as the first global pediatric Center of Excellence for using this technology to help patients with specific types of childhood tumors.

Researchers awarded $3.5 million to study brain and cranium development in children

October 1, 2021

Currently, studies on typical brain and cranium development are limited. One reason for this is that imaging techniques are optimized to best visualize either bone or soft tissue, but not both.

With prevalence of developmental disorders on the rise, the need to understand brain development has never been more critical. Development of the brain is strongly influenced by the cranium, but this relationship has not been adequately studied because of limitations in imaging technology. Now, researchers from Children’s Hospital Los Angeles and Children’s National Hospital are working together to develop techniques that will provide greater insight into this relationship. Their studies will be funded by The National Institute of Dental and Craniofacial Research, which has awarded them $3.5 million.

Natasha Leporé, Ph.D., of Children’s Hospital Los Angeles, studies methods to interpret brain imaging data. “There’s a lot of interaction between the skull and the brain,” she says, “and we want to better understand how they grow together.”

Currently, studies on typical brain and cranium development are limited. One reason for this is that imaging techniques are optimized to best visualize either bone or soft tissue, but not both.

The brain — mostly composed of water, protein and fat — doesn’t show up well on computerized tomography (CT) scans, which use X-ray images. In addition, radiation exposure limits the amount of CT scan data available in children. On the other hand, magnetic resonance imaging (MRI) scans are excellent for brain images but are not optimal for surrounding bone.

This presents researchers with a dilemma if they want to see the brain and the skull together in one image. Fortunately, research barriers like these are often overcome by collaboration.

Leporé will work with Marius George Linguraru, D.Phil, M.A., MS.c., principal investigator in the Sheikh Zayed Institute for Pediatric Surgical Innovation at Children’s National Hospital.

Linguraru works on a set of tools for cranial phenotyping, using existing CT images from typically developing children. In their collaboration, Leporé and Linguraru will extend the tools to MRI scans, allowing the team to analyze the brain and cranium simultaneously. The pair has received a $3.5 million award over 5 years.

“The tools we develop together will help us to better understand the healthy growth of children,” says Linguraru. “We will have the ability to analyze the joint cranial and brain development from large medical image datasets of pediatric patients.”

This, the team says, will be invaluable to the medical community.

“These tools will help clinicians to better assess, diagnose and plan treatment for infants with cranial deformities,” says Linguraru.

Collaborations like this allow expertise to be shared across specialties, ultimately benefiting children in need. Exceptional pediatric care is a result of teamwork; not only doctors, nurses and clinical staff, but also biomedical research, which arms clinicians with the information they depend on.

“We need to have a clear idea of what is expected in normal development,” says Leporé. “This allows doctors to detect and better understand differences in development.”

Other members of the research team include: Vidya Rajagopalan, Ph.D.; Marvin Nelson, M.D.; Alexis Johns, Ph.D.; Niharika Gajawelli, Ph.D. (from Children’s Hospital Los Angeles and University of Southern California); Robert Keating, M.D. (Children’s National Hospital); Yalin Wang, Ph.D. (Arizona State University); Antonio Porras, Ph.D. (University of Colorado); Sean Deoni, Ph.D. (Rhode Island Hospital and Brown University).

Family love and the right care for neurofibromatosis type 1 give Maddox a fresh start

December 14, 2020

Maddox and his family in early 2020.

13-year-old Maddox Gibson is learning to cook. He says he wants to be a chef and wants to make meals for people who need it most — the homeless and the hungry.

It makes sense that he’s eager to help people who need it. As a young child growing up in a group home in his native country of China, he knows firsthand how important that support can be. In 2017 at age 10, he found his own endless supply of love and support when he met and was adopted by the Gibson family.

Zhen Chao, now called Maddox, was born in China with a genetic condition called neurofibromatosis type 1 that can cause painful or disfiguring tumors called plexiform neurofibromas. Zhen Chao had two on his head when he arrived — on his scalp and on his left optic nerve — which had been largely untreated for most of his life in China. On top of that, his right leg had been fractured and not fixed properly years before, causing him pain and weakness that left him wheelchair bound.

Adoptive mom Lindsey, a registered nurse, knew he would need special care to meet all the unique challenges he faced, and she’d done her homework — he needed the expertise of Miriam Bornhorst, M.D., and the Gilbert Family Neurofibromatosis Institute at Children’s National Hospital to help him thrive in his new life in the U.S. Since shortly after he came to the U.S., Lindsey has been driving Maddox the 6-plus hours from their home in North Carolina to Washington, D.C., regularly, to get care for all of his health challenges.

Maddox’s optic neurofibroma was too large when he arrived at Children’s National for a simple surgical removal. Due to her role as the lead investigator on a cutting edge clinical trial for the orphan drug selumetinib — a so-called MEK inhibitor that has shown early promise at reducing the cell growth of tumors like plexiform neurofibromas, Dr. Bornhorst enrolled Maddox in a compassionate use program for the drug, an opportunity that is not widely available. The drug was initially developed for something completely different — treatment of melanoma and non-small cell lung cancer in adults–but has been adapted through its FDA orphan drug designation for pediatric clinical trials in NF1. In the time since Maddox started taking it, it was approved for use in NF1 patients by the FDA.

The trial drug did its job — in late 2019, Maddox’s tumor had shrunk enough that chief neurosurgeon Robert Keating, M.D., and plastic surgeon Michael Boyajian, M.D., were able to successfully remove it. Follow-up procedures led by that team have also worked to repair the tissue that was impacted by the optic neurofibroma.

In addition to treatment of his neurofibromas, Maddox and his mom are able to see every service they need during one stay in D.C. The Neurofibromatosis Institute works closely across specialties, so his corrective surgery for his leg from Children’s chief of orthopaedics, Matthew Oetgen, M.D., MBA, in September 2019. He was assessed and prescribed physical therapy early in the process and even before surgery, so now he’s stronger than ever and walking. Learning difficulties, including autism and ADHD are common in NF1 patients, and so the NF Institute’s neuropsychology team has evaluated him and worked with the family to find resources and strategies near home that will support him. It should be noted, those learning difficulties only became apparent after Maddox taught himself English from scratch in only two years’ time with the help of his school’s ESOL program.

This kind of full spectrum care, from clinical assessment to surgical treatment and psychological supports, is crucial to the lives of patients with neurofibromatosis type 1 and is only available at a pediatric specialty care institution like Children’s National. The hospital has gathered some of the preeminent researchers, surgeons, and physicians within the NF Institute to make sure that the care families will travel hundreds of miles to receive is the best possible, using the latest evidence-based treatments for every challenge they face.

Though his care and follow-ups will continue at Children’s National Hospital and his condition may pose new challenges in the future, for now, Maddox is able to focus on exploring new things and doing what he loves — playing outdoors with his family, learning to cook and building with Legos.
