Quick. Name four pillar pediatric organizations on the vanguard of advancing pediatric research.

Most researchers and clinicians can rattle off the names of the Academic Pediatric Association, the American Academy of Pediatrics and the American Pediatric Society. But that fourth one, the Society for Pediatric Research (SPR), is a little trickier. While many know SPR, a lot of research-clinicians simply do not.

Over the next few years, Beth A. Tarini, M.D., MS, will make it her personal mission to ensure that more pediatric researchers get to know SPR and are so excited about the organization that they become active members. In May 2019 Dr. Tarini becomes Vice President of the society that aims to stitch together an international network of interdisciplinary researchers to improve kids’ health. Four-year SPR leadership terms begin with Vice President before transitioning to President-Elect, President and Past-President, each for one year.

Dr. Tarini says she looks forward to working with other SPR leaders to find ways to build more productive, collaborative professional networks among faculty, especially emerging junior faculty. “Facilitating ways to network for research and professional reasons across pediatric research is vital – albeit easier said than done. I have been told I’m a connector, so I hope to leverage that skill in this new role,” says Dr. Tarini, associate director for Children’s Center for Translational Research.

“I’m delighted that Dr. Tarini was elected to this leadership position, and I am impressed by her vision of improving SPR’s outreach efforts,” says Mark Batshaw, M.D., Executive Vice President, Chief Academic Officer and Physician-in-Chief at Children’s National. “Her goal of engaging potential members in networking through a variety of ways – face-to-face as well as leveraging digital platforms like Twitter, Facebook and LinkedIn – and her focus on engaging junior faculty will help strengthen SPR membership in the near term and long term.”

Dr. Tarini adds: “Success to me would be leaving after four years with more faculty – especially junior faculty – approaching membership in SPR with the knowledge and enthusiasm that they bring to membership in other pediatric societies.”

SPR requires that its members not simply conduct research, but move the needle in their chosen discipline. In her research, Dr. Tarini has focused on ensuring that population-based newborn screening programs function efficiently and effectively with fewer hiccups at any place along the process.

Thanks to a heel stick to draw blood, an oxygen measurement, and a hearing test, U.S. babies are screened for select inherited health conditions, expediting treatment for infants and reducing the chances they’ll experience long-term health consequences.

“The complexity of this program that is able to test nearly all 4 million babies in the U.S. each year is nothing short of astounding. You have to know the child is born – anywhere in the state – and then between 24 and 48 hours of birth you have to do testing onsite, obtain a specific type of blood sample, send the blood sample to an off-site lab quickly, test the sample, find the child if the test is out of range, get the child evaluated and tested for the condition, then send them for treatment. Given the time pressures as well as the coordination of numerous people and organizations, the fact that this happens routinely is amazing. And like any complex process, there is always room for improvement,” she says.

Dr. Tarini’s research efforts have focused on those process improvements.

As just one example, the Advisory Committee on Heritable Disorders in Newborns and Children, a federal advisory committee on which she serves, was discussing how to eliminate delays in specimen processing to provide speedier results to families. One possible solution floated was to open labs all seven days, rather than just five days a week. Dr. Tarini advocated for partnering with health care engineers who could help model ways to make the specimen transport process more efficient, just like airlines and mail delivery services. A more efficient and effective solution was to match the specimen pick-up and delivery times more closely with the lab’s operational times – which maximizes lab resources and shortens wait times for parents.

Conceptual modeling comes so easily for her that she often leaps out of her seat mid-sentence, underscoring a point by jotting thoughts on a white board, doing it so often that her pens have run dry.

“It’s like a bus schedule: You want to find a bus that not only takes you to your destination but gets you there on time,” she says.

Dr. Tarini’s current observational study looks for opportunities to improve how parents in Minnesota and Iowa are given out-of-range newborn screening test results – especially false positives – and how that experience might shake their confidence in their child’s health as well as heighten their own stress level.

“After a false positive test result, are there parents who walk away from newborn screening with lingering stress about their child’s health? Can we predict who those parents might be and help them?” she asks.

Among the challenges is the newborn screening occurs so quickly after delivery that some emotionally and physically exhausted parents may not remember it was done. Then they get a call from the state with ominous results. Another challenge is standardizing communication approaches across dozens of birthing centers and hospitals.

“We know parents are concerned after receiving a false positive result, and some worry their infant remains vulnerable,” she says. “Can we change how we communicate – not just what we say, but how we say it – to alleviate those concerns?”

The traction sisters

Spinal-halo-gravity traction times three

The traction sisters

Three girls received spinal-halo-gravity traction at the same time at Children’s National prior to surgery for acute idiopathic scoliosis.

Washington, D.C.’s ABC affiliate, WJLA, recently featured a story about three girls who received treatment for acute idiopathic scoliosis through the Children’s National Spinal Fusion Surgical Home, a comprehensive and effective program that has demonstrated reductions in pain medication usage and medical stays following posterior spinal fusion surgery.

All three girls had extremely severe curvatures of the spine requiring a month long inpatient stay for spinal halo-gravity traction prior to surgical intervention. Spinal curves severe enough to require traction are rare, and often impede a child’s quality of life just as severely – eating, breathing and moving are difficult. Given the long hospital stay required and the challenges of asking a child to stay in a traction frame 23 hours out of every day, the orthopaedic surgery team tries to coordinate cases so that when possible, patients can support each other throughout the process. This was the first time, however, that the team had three traction patients on similar trajectories on the unit at the same time.

Spinal halo-gravity traction can reduce the degree of surgical intervention necessary by accomplishing some pre-operative gradual straightening of the spine prior to spinal fusion procedures. For severe spinal deformities this has been shown to improve the safety and effectiveness of the final surgical procedure.

Eliminating unnecessary radiation exposure from spinal radiography

Chief of Orthopaedics and Sports Medicine Matthew Oetgen, M.D., discusses an image of a patient’s spine.

If a child arrives at the pediatric orthopaedic specialist for an idiopathic scoliosis evaluation without an adequate radiographic image of his or her spine, it’s often necessary to order yet another imaging study for accurate assessment.

A study published in the Journal of the American Academy of Orthopaedic Surgeons found that in a 6 month period, almost half (43 percent) of patients referred for evaluation required a repeat radiograph due to missing or poor quality existing images.

“Repeating the radiograph means these kids received another exposure to radiation, too,” says Matthew Oetgen, M.D., the study’s lead author and chief of Orthopaedic Surgery and Sports Medicine at Children’s National Health System. “It’s frustrating because in many cases, a simple change in how the initial radiograph was taken could have prevented the need for more imaging studies.”

Dr. Oetgen and the study authors note that there is currently no standardized protocol for spinal radiography of suspected idiopathic scoliosis. However, a few basic criteria could greatly reduce the number of repeat images necessary. Radiographic images that allow for proper evaluation of idiopathic scoliosis and reduce radiation exposure include:

  • A full coronal view of the spine including skull base and pelvis
  • The iliac crest as an indicator of skeletal maturity
  • A full-length lateral view of the spine

Study authors also reinforced the need to do everything possible to reduce radiation exposure for children through proper use of protective shielding for reproductive organs and digital radiograph technology.

“Orthopaedic surgeons and pediatricians share the responsibility to ensure children are exposed to as little iatrogenic radiation as possible,” Dr. Oetgen concludes. “All physicians should be sure that the radiology facilities they refer patients to for spinal radiography employ every technology and safety measure available to limit radiation exposure. Additionally, we can and should work with radiologists to define evaluation criteria and improve what’s captured by radiography on the first try.”

Understanding Legg-Calvé-Perthes disease

Dr. Benjamin Martin examines a patient

Legg-Calvé-Perthes disease, which affects between five and 10 of every 100,000 children each year, is so rare that it can sometimes be challenging for clinicians to know how best to care for affected patients.

That’s why in 2011 a group of pediatric orthopaedic specialists led by Texas Scottish Rite Children’s Hospital created an international study group dedicated to using research to improve the care of kids with Perthes, a hip disorder characterized by a loss of blood flow to the immature femoral head. Children’s National orthopaedic surgeon Benjamin Martin, M.D., has participated in the group since its launch.

Recently, Dr. Martin and two study group colleagues published a review study that outlines common imaging modalities used in the diagnosis and treatment of Perthes disease.

“There are many imaging options out there, including recent advances in MRI, that can add to our knowledge of the disease and how to treat it so kids have optimal outcomes,” Dr. Martin says. “Our goal was to review what’s out there, how it’s used, and identify any shortcomings of these approaches for this particular patient population.”

The authors note that imaging, in various forms, has been a crucial contributor to understanding and treatment of this disease since it was first discovered. Today, radiography remains the most common imaging technique used to diagnose and follow Perthes over time. However, some MRI applications may offer additional insight into the disorder.

Perfusion MRI allows for early understanding of extent of disease and perfusion patterns may correlate with outcomes. Diffusion weighted imaging (DWI) MRI is another promising avenue for tracking disease progression. Additionally, dynamic MRI might provide range of motion assessments that could be used in the surgical planning process.

This study was one of a handful that the international Perthes group has published so far, with several more currently under development. Exploring treatments and technology applications will enhance early diagnosis and treatment for Perthes, which is a crucial component of treatment success and improved quality of life for affected children.

Creating better casts

/in , , , /by

Each year, millions of children in the U.S. come to hospital emergency departments with fractures. While broken bones are commonplace, the expertise to stabilize these injuries and cast them is not, says Children’s National Health System orthopedic surgeon Shannon Kelly, M.D.

Most fractures are casted by an on-call resident without the assistance of an orthopedist, she explains. Whether that resident applies a cast successfully depends largely on how well he or she learned this skill as an intern. While most current training models have interns take calls with residents, picking up casting skills through hands-on experience from their more senior peers, they can also pick up mistakes – which get repeated once they’re caring for patients independently as residents themselves, Kelly says.

Casting mistakes aren’t trivial, she adds. They can have serious consequences for patients. For example, a cast that’s not tight enough in the right places can leave bones vulnerable to shifting, a scenario that doctors call a loss in reduction, Kelly explains. If bones aren’t in the right position to heal, doctors must reposition them either in the operating room, often exposing patients to general anesthesia, or through painful, in-office procedures.

Conversely, casts that are too tight – particularly on a fresh fracture that’s prone to swelling – can damage tissues from loss of circulation. To avoid this latter problem, doctors often create a “bivalve” cast in which the two halves are split like a clamshell, leaving room for tissues to expand. But they must use extreme care when they cut open the cast with a saw to avoid cutting patients with the rotating blade or burning them with heat generated from its friction.

“Each year, thousands of children are harmed from improper casting and must go through additional procedures to fix the damage done,” Kelly says.

That’s why she and her colleagues are developing a better way to train interns before they start their orthopedics rotation. Starting this spring, the team will be directing a series of casting workshops to train interns on the proper casting technique.

The workshops will take advantage of models that allow interns to practice without harming patients. Some of these models have simulated bones that show up on an X-ray, allowing participants to evaluate whether they achieved a good reduction once they’re finished. Other models are made of wax that melts if the heat of a cast saw becomes too intense and show nicks if the blade makes contact. Learning proper technique using this tool can help spare human patients painful burns and cuts, Kelly says.

To broaden this effort beyond Children’s National, Kelly and her colleagues received a $1,000 microgrant from the Pediatric Orthopaedic Society of North America to create videos based on material from these workshops. These videos will help trainees at medical institutions across the country learn the same pivotal casting skills.

“A broken bone is difficult enough,” Kelly says. “We’re hoping to decrease the number of times that a child has to have an unnecessary procedure on top of that from a casting mistake that could have been avoided.”

Pedbot’s next step – Home-based therapy

/in , , , , , , , /by
Pedbot video game

Pedbot’s home version adapts the same airplane-themed video game to a smaller therapeutic platform that is more affordable to build.

The novel ankle rehabilitation robot built at Children’s National to help children with cerebral palsy build ankle strength and control through video gaming is taking a big step forward. Engineers have created a smaller, more affordable version of the robotic platform using 3D printed parts, to explore the effectiveness of a home-based therapy program.

“We’re seeing preliminary success in our trial for in clinic use of the Pedbot. Now we’re hoping to see if making the technology accessible at home means that 1) Kids use it more often and 2) More frequent, regular use over time leads to better range of motion,” says Kevin Cleary, Ph.D., the Sheikh Zayed Institute for Pediatric Surgical Innovation’s bioengineering technical director and engineering lead for Pedbot.

Pedbot’s video game, designed by software engineer Hadi Fooladi, M.S., allows kids to pilot an airplane through a series of hoops at varying speeds as determined by the therapist and programmer. The game isn’t the only thing that’s unique about this therapeutic robot, however.

Just like the clinic version, the home model moves in three translational directions (x, y and z) and rotates about three axes (the x, y and z axes), similar to the movement of a flight simulator. The result is a robot that helps the patient exercise across a greater range of motion and build muscle strength in a way that more closely mimics real-life ankle function.

Pedbot Home potentially eliminates an additional major therapeutic barrier – the clinic appointment.

“The great thing about Pedbot is you’re constantly working to reach a moving target, and the therapist can vary the movement type as much or as little as needed for each patient,” says Catherine Coley, DPT, a physical therapist at Children’s National who is a member of the Pedbot development team. “We think the home version might make it easier for the child to succeed with a long term therapy program by removing the need for repeat clinic visits.”

“What if a child could come home from school and do their therapy at home after dinner? Would doing it every day for 20 minutes benefit the child more than just coming to see us once or twice a week for an hour? Can we make it easier for our patients to cooperate and follow through with therapy homework? These are some of the questions that we hope we can answer during our trial for the home version,” says Sally Evans, M.D., division chief of Pediatric Rehabilitation Medicine at Children’s National and clinical lead for the project.

The cross-functional Pedbot team includes engineers Reza Monfaredi Ph.D. and Tyler Salvador, B.S., as well as additional physical therapists, Stacey Kovelman, P.T. and Justine Belchner, P.T., and Sara Alyamani, B.A. Future expansions will include the addition of electromyography measurements in collaboration with Paola Pergami, M.D., Ph.D. and incorporation of other patient populations with Beth Wells, M.D.

Pedbot Home is currently being piloted in the home setting, with the goal of enrolling additional families to participate in a trial within the next year. The work is supported by a $500,000 federal grant from the Department of Health and Human Services’ National Institute on Disability, Independent Living, and Rehabilitation Research.

E coli bacteria

Urinary bacteria in spinal cord injury cases may tip balance toward UTIs

/in , , , , , , /by
E coli bacteria

Patients with spinal cord injuries nearly universally have bacteria present in their urine regardless of whether they have a urinary tract infection.

The fallout from spinal cord injury doesn’t end with loss of mobility: Patients can have a range of other issues resulting from this complex problem, including loss of bladder control that can lead to urine retention. One of the most serious implications is urinary tract infections (UTIs), the most common cause of repeat hospitalization in people with spinal cord injuries, explains Hans G. Pohl, M.D., associate chief in the division of Urology at Children’s National Health System.

Diagnosing UTIs in people with spinal cord injuries is trickier than in people who are otherwise healthy, Dr. Pohl explains. Patients with spinal cord injuries nearly universally have bacteria present in their urine regardless of whether they have a UTI. It’s unclear whether these bacteria are innocent bystanders or precursors to UTIs in patients who don’t yet show symptoms. And although antibiotics can wipe out this bacterial population, these drugs can have undesirable side effects and frequent use can promote development of antibiotic-resistant bacteria.

Although clinical dogma has long promoted the idea that “healthy” urine is sterile, Dr. Pohl and colleagues have shown that a variety of bacteria live in urine, even in people without symptoms. These microorganisms, like the intestinal microbiome, live in harmony with their hosts and may even help promote health. However, it’s unclear what this urinary microbiome might look like for patients with spinal cord injury before, during and after UTIs.

To start investigating this question, Dr. Pohl and co-authors recently reported a case study they published online Sept. 21, 2018, in Spinal Cord Series and Cases. The case report about a 55-year-old man who had injured the thoracic segment of his spinal cord—about the level of the bottom of his shoulder blades—in a skiing accident when he was 19 was selected as “Editor’s Choice” for the journal’s October 2018 issue.  The patient had a neurogenic bladder, which doesn’t function normally due to impaired communication with the spinal cord. To compensate for this loss of function, this patient needed to have urine removed every four to six hours by catheterization.

Over eight months Dr. Pohl, the study’s senior author, and colleagues collected 12 urine samples from this patient:

  • One was collected at a time the patient didn’t show any symptoms of a UTI
  • Nine were collected when the patient had UTI symptoms, such as bladder spasticity
  • Two samples were collected when the patient had finished antibiotic treatment for the UTI.

The researchers split each sample in half. One part was put through a standard urinalysis and culture, much like what patients with a suspected UTI would receive at the doctor’s office. The other part was analyzed using a technique that searched for genetic material to identify bacteria that might be present and to estimate their abundance.

The researchers found a variety of different bacteria present in these urine samples. Regardless of the patient’s health status and symptoms, the majority of these bacterial species are known to be pathogenic or potentially pathogenic. By contrast, this patient’s urine microbiome appeared to largely lack bacterial species known to be either neutral or with potentially probiotic properties, such as Lactobacillus.

All of the bacteria that grew in culture also were identified by their genetic material in the samples. However, genetic sequencing also identified a possible novel uropathogenic species called Burkholderia fungorum that didn’t grow in the lab in five of the samples. This bacterium is ubiquitous in the environment and has been identified in soil- and plant-based samples. It also has been discovered in the respiratory secretions of patients with cystic fibrosis, in patients with a heart condition called infectious endocarditis, in the vaginal microbiota of patients with bacterial vaginosis, and in the gut of patients with HIV who have low T-cell counts. Dr. Pohl says it’s unclear whether this species played an infectious role in this patient’s UTI or whether it’s just part of his normal urine flora.

“Consistent with our previous work, this case report demonstrates that rather than healthy urine being sterile, there is a diverse urine bacterial ecosystem during various states of health and disease,” Dr. Pohl says. “Rather than UTIs resulting from the growth or overgrowth of a single organism, it’s more likely that a change in the healthy balance of the urine ecosystem might cause these infections.”

By monitoring the relative abundance of different bacteria types present in the urine of patients with spinal cord injury and combining this information with a patient’s symptoms, Dr. Pohl says doctors may be able to make more accurate UTI diagnoses in this unique population.

In addition to Dr. Pohl, study co-authors include Marcos Pérez-Losada, Ljubica Caldovic, Ph.D., Bruce Sprague and Michael H. Hsieh, M.D., Children’s National; Emma Nally, Suzanne L. Groah and Inger Ljungberg, MedStar National Rehabilitation Hospital; and Neel J. Chandel, Montefiore Medical Center.

Breakthrough device objectively measures pain type, intensity and drug effects

Pediatric anesthesiologist Julia C. Finkel, M.D., of Children’s National Health System, gazed into the eyes of a newborn patient determined to find a better way to measure the effectiveness of pain treatment on one so tiny and unable to verbalize. Then she realized the answer was staring back at her.

Armed with the knowledge that pain and analgesic drugs produce an involuntary response from the pupil, Dr. Finkel developed AlgometRx, a first-of-its-kind handheld device that measures a patient’s pupillary response and, using proprietary algorithms, provides a diagnostic measurement of pain intensity, pain type and, after treatment is administered, monitors efficacy. Her initial goal was to improve the care of premature infants. She now has a device that can be used with children of any age and adults.

“Pain is very complex and it is currently the only vital sign that is not objectively measured,” says Dr. Finkel, who has more than 25 years of experience as a pain specialist. “The systematic problem we are facing today is that healthcare providers prescribe pain medicine based on subjective self-reporting, which can often be inaccurate, rather than based on an objective measure of pain type and intensity.” To illustrate her point, Dr. Finkel continues, “A clinician would never prescribe blood pressure medicine without first taking a patient’s blood pressure.”

The current standard of care for measuring pain is the 0-to-10 pain scale, which is based on subjective, observational and self-reporting techniques. Patients indicate their level of pain, with zero being no pain and ten being highest or most severe pain. This subjective system increases the likelihood of inaccuracy, with the problem being most acute with pediatric and non-verbal patients. Moreover, Dr. Finkel points out that subjective pain scores cannot be standardized, heightening the potential for misdiagnosis, over-treatment or under-treatment.

Dr. Finkel, who serves as director of Research and Development for Pain Medicine at the Sheikh Zayed Institute for Pediatric Surgical Innovation at Children’s National, says that a key step in addressing the opioid crisis is providing physicians with objective, real-time data on a patient’s pain level and type, to safely prescribe the right drug and dosage or an alternate treatment.,

She notes that opioids are prescribed for patients who report high pain scores and are sometimes prescribed in cases where they are not appropriate. Dr. Finkel points to the example of sciatica, a neuropathic pain sensation felt in the lower back, legs and buttocks. Sciatica pain is carried by touch fibers that do not have opioid receptors, which makes opioids an inappropriate choice for treating that type of pain.

A pain biomarker could rapidly advance both clinical practice and pain research, Dr. Finkel adds. For clinicians, the power to identify the type and magnitude of a patient’s nociception (detection of pain stimuli) would provide a much-needed scientific foundation for approaching pain treatment. Nociception could be monitored through the course of treatment so that dosing is targeted and personalized to ensure patients receive adequate pain relief while reducing side effects.

“A validated measure to show whether or not an opioid is indicated for a given patient could ease the health care system’s transition from overreliance on opioids to a more comprehensive and less harmful approach to pain management,” says Dr. Finkel.

She also notes that objective pain measurement can provide much needed help in validating complementary approaches to pain management, such as acupuncture, physical therapy, virtual reality and other non-pharmacological interventions.

Dr. Finkel’s technology, called AlgometRx, has been selected by the U.S. Food and Drug Administration (FDA) to participate in its “Innovation Challenge: Devices to Prevent and Treat Opioid Use Disorder.” She is also the recipient of Small Business Innovation Research (SBIR) grant from the National Institute on Drug Abuse.

Osteochondritis dissecans: Deciding the best candidates for nonoperative treatment

/in , /by
Emily Niu

“When patients come to see me with this condition, they’re often at their lowest point. But then I get to watch them go through this transformation as they’re getting better,” says Emily Niu, M.D. “It’s really wonderful to see someone’s personality blossom over the course of treatments.”

The adage of “practice makes perfect” is true for young competitive athletes; however it also puts them at risk for overuse injuries. One of these injuries is a condition called osteochondritis dissecans (OCD), in which repeatedly overloading joints causes increased stress to certain areas of bone. This area of bone can lose its blood supply, become unhealthy and ultimately end up fragmented. In the late stages, this area of bone can break off from the surrounding healthy bone and as a result, the overlying cartilage (which relies on the bone for a foundation) can become prone to damage. This process can be likened to the formation of potholes in a road. Typically, individuals affected can have pain, limited range of motion or even arthritis down the line.

This condition can happen at different locations throughout the body, including the knees, ankles and elbows. Baseball players and gymnasts are particularly prone to getting OCD of the capitellum, or the outside of the elbow, from throwing or tumbling.

If this injury is unstable, with bone and cartilage already fragmenting, it’s typically treated with surgery, explains Emily Niu, M.D., a Children’s National orthopaedic surgeon. Stabilizing the fragment and drilling tunnels in the affected bone surface allows new bone to grow and repair the defect. But for stable OCD, the treatment path is unclear.

Sometimes nonoperative treatments, such as rest, physical therapy or bracing the joint, can allow it to fully heal over time; however, she says, some patients treated nonoperatively may not be able to heal and will still require surgery later.

What distinguishes these two groups has thus far been unclear. Dr. Niu adds that there are few studies that have looked at what characteristics might make patients better candidates for a surgical or nonoperative route. The studies that do exist are limited to very small groups of patients.

To help doctors and their patients make more informed decisions, Dr. Niu and her colleagues performed a retrospective review of 89 patients aged 18 years old and younger treated at Boston Children’s Hospital for stable OCD of the capitellum. The vast majority of these 49 male and 40 female patients were baseball players and gymnasts. Most had just a single elbow affected; four patients (all gymnasts) experienced this problem in both elbows.

Each of these patients was initially treated nonoperatively, with activity restriction, physical therapy and progressive return to activity at the discretion of the treating physician. During this time, all of the athletes had elbow radiographs, elbow MRIs or both to image the injury and follow its healing process.

The researchers report in the November 2018 that just over half of these 93 elbows healed successfully with nonoperative treatments, taking an average of about eight months for symptoms to subside and imaging to show that the bone had healed properly.

When Dr. Niu and her colleagues looked for characteristics that might have influenced whether nonoperative treatments worked or didn’t, they didn’t find any difference in the two groups with age, bone maturity, sex, hand dominance or sport. However, the healing group had symptoms for an average of four months shorter than the non-healing group before they sought treatment. Those patients with bone lesions without clear margins visible on MRI were more likely to heal than those with clear margins, as were those without cyst-like lesions on their bones – both signs of a more advanced process. In addition, those whose bone lesions were relatively small were more likely to heal than those with larger lesions compared to the size of their bones.

Dr. Niu notes that OCD can be a devastating injury for young athletes, interrupting their participation in sports on average for a minimum of six months and significantly longer if nonoperative treatments fail and surgery becomes necessary. Being able to shave some time off that schedule with better knowledge of which type of treatment is most likely to work, she says, can help her patients get back to doing what they love significantly faster.

“When patients come to see me with this condition, they’re often at their lowest point. But then I get to watch them go through this transformation as they’re getting better,” Dr. Niu says. “It’s really wonderful to see someone’s personality blossom over the course of treatments. It’s such a relief for both of us when they’re back where they want to be.”

Femoral fracture

Broken system? Pain relief for fractures differs by race/ethnicity

/in , , , , , , , /by
Femoral fracture

Data collected by a multi-institutional research team show that kids’ pain from long bone fractures may be managed differently in the emergency department depending on the child’s race and ethnicity.

Children who experience broken bones universally feel pain. However, a new multi-institutional study presented at the American Academy of Pediatrics (AAP) 2018 National Conference & Exhibition suggests that emergency treatment for this pain among U.S. children is far from equal. Data collected by the research team show that kids’ pain may be managed differently in the emergency department depending on the child’s race and ethnicity. In particular, while non-Latino black children and Latino children are more likely to receive any analgesia, non-white children with fractured bones are less likely to receive opioid pain medications, even when they arrive at the emergency department with similar pain levels.

“We know from previously published research that pain may be treated differentially based on a patient’s race or ethnicity in the emergency department setting. Our prior work has demonstrated that racial and ethnic minorities are less likely to receive opioid analgesia to treat abdominal pain, even when these patients are diagnosed with appendicitis,” says study leader Monika K. Goyal, M.D., MSCE, assistant division chief and director of Academic Affairs and Research in the Division of Emergency Medicine at Children’s National Health System. “Emergency departments delivering evidence-based care should treat all pediatric patients consistently. These findings extend our work by demonstrating that children presenting with long bone fractures also experience differential treatment of pain based on their race or ethnicity.”

The AAP calls appropriately controlling children’s pain and stress “a vital component of emergency medical care” that can affect the child’s overall emergency medical experience. Because fractures of long bones – clavicle, humerus, ulna, radius, femur, tibia, fibula – are commonly managed in the emergency department, the research team tested a hypothesis about disparities in bone fracture pain management.

They conducted a retrospective cohort study of children and adolescents 21 and younger who were diagnosed with a long bone fracture from July 1, 2014, through June 30, 2017. They analyzed deidentified electronic health records stored within the Pediatric Emergency Care Applied Research Network Registry, which collects data from all patient encounters at seven pediatric emergency departments.

During that time, 21,642 patients with long bone fractures met the study inclusion criteria and experienced moderate to severe pain, rating four or higher on a 10-point pain scale. Some 85.1 percent received analgesia of any type; 41.5 percent received opioid analgesia. Of note:

  • When compared with non-Hispanic white children, minority children were more likely to receive pain medication of any kind (i.e. non-Latino black patients were 58 percent more likely to receive any pain medication, and Latino patients were 23 percent more likely to receive any pain medication).
  • When compared with non-Latino white children, minority children were less likely to receive opioid analgesia (i.e., non-Latino black patients were 30 percent less likely to receive opioid analgesia, and Latino patients were 28 percent less likely to receive opioid analgesia).

“Even though minority children with bone fractures were more likely to receive any type of pain medication, it is striking that minority children were less likely to receive opioid analgesia, compared with white non-Latino children,” Dr. Goyal says. “While it’s reassuring that we found no racial or ethnic differences in reduction of patients’ pain scores, it is troubling to see marked differences in how that pain was managed.”

Dr. Goyal and colleagues are planning future research that will examine the factors that inform how and why emergency room physicians prescribe opioid analgesics.

“Our primary goal was to improve the value of care for children with scoliosis and their families,” says Dr. Oetgen. “Even better, we’ve shown that this model can be used consistently over time to maintain the benefits it delivers to this patient population.”

“Creating an effective process that benefits patients, is sustainable long term and doesn’t increase costs is one of the most challenging parts of any new procedure, both in health care and beyond,” says Matt Oetgen, M.D., chief of Orthopaedic Surgery and Sports Medicine at Children’s National.

Dr. Oetgen’s team accomplished this feat when building the Children’s National Spinal Fusion Surgical Home. The team used LEAN process mapping at the outset to engage a broad group of care providers who established a collaborative environment that empowered and engaged everyone to take ownership over a new care pathway for every patient who undergoes posterior spinal fusion surgery at the hospital.

This unique model designed using proven business process development tools has allowed patients require fewer pain medications after surgery and have shorter stays in the hospital. Even better, the team has maintained the integrity of the pathway consistently over a longer period of time than any other pediatric spinal fusion care model to date.

“Our primary goal was to improve the value of care for children with scoliosis and their families,” says Dr. Oetgen, who was the study’s lead author. “Even better, we’ve shown that this model can be used consistently over time to maintain the benefits it delivers to this patient population.”

The team conducted a retrospective analysis of prospective data from all patients (213) undergoing posterior spinal fusion at Children’s National Health System from 2014 to 2017, a period of time that captures nearly one year  before implementation of the new pathway and 2.5 years after implementation. The outcomes were reported in the Journal of Bone and Joint Surgery.

As pressure builds to increase the value of care, many hospital systems are trying standardized care pathways for many complex conditions, in an effort to decrease care variability, improve outcomes and decrease cost. Previous research has shown the effectiveness of a variety of standardized pathways with wide ranging goals for spinal fusion procedures, however, most published studies have focused only on the initial success of these pathways. This study is the first to look at the implementation over a period of 2.5 years to gauge whether the process and its effectiveness could be maintained long term.

The authors attribute physician buy-in across disciplines and strict adherence to pathway processes as key to the success of this model. In addition, the team created standardized educational procedures for onboarding new care providers and implemented standardized electronic order sets for both orthopaedic and anesthesia services to make the pathway easy to maintain with little deviation over time. Lean process mapping at the outset included a broad group of care providers who established a collaborative environment that empowered and engaged the entire team to take ownership over the new process.

“We used proven business models for culture change that were critical to the success of this program,” Dr. Oetgen says. “We’re proud of the model we have created and think it would work well in other pediatric hospitals with similar patient populations.”

Children’s National Health System is now part of a growing Duchenne care network, becoming the newest member of the Parent Project Muscular Dystrophy’s (PPMD) Certified Duchenne Care Program.

The certification process to become a Certified Duchenne Care Center (CDCC) was grounded in the idea that comprehensive Duchenne care and services should be available and accessible to as many families as possible. By joining the network of PPMD Certified Duchenne Care Centers and standardizing care, Children’s National’s Neuromuscular Medicine Program is also improving Duchenne research and clinical trials by decreasing variability in care and increasing the quality of clinical trial outcome measures. This results in accelerating the time it takes therapies to reach the patients who need them.

By allowing neuromuscular patients of all diagnoses access to the comprehensive teams of sub-specialists serving the Duchenne population, Children’s National and other PPMD Certified Duchenne Care Centers will improve the care of all patients with neuromuscular diagnoses.

New robotic therapies for cerebral palsy

/in , , , /by

The hippobot is a mechanical horseback riding simulator that provides hippotherapy for children.

Cerebral palsy is the most common type of movement disorder in children, affecting 1 in 500 babies born each year. For these infants, learning to sit up, stand and walk can be a big challenge which often requires years of physical therapy to stretch and strengthen their muscles. A team led by Kevin Cleary, Ph.D., technical director of the Bioengineering Initiative at Children’s National Health System, and Sally Evans, M.D., director of Pediatric Rehabilitation Medicine at Children’s National, has created two new types of robotic therapy that they hope will make physical therapy more enjoyable and accessible for children.

Hippobot equine therapy simulator

One of the most effective types of therapy for children with cerebral palsy is hippotherapy, which uses horseback riding to rehabilitate children with neurological and musculoskeletal disabilities. The movement of horses helps riders with cerebral palsy improve endurance, balance and core strength, which in turns helps them gain the ability to sit without support. If a child with cerebral palsy does not master independent sitting early in life, he or she may never gain the ability to stand or walk. Unfortunately, many children never have the chance to experience hippotherapy due to geographical constraints and cost issues.

To increase patient access to hippotherapy, the bioengineering team (Reza Monfaredi, Ph.D.; Hadi Fooladi Talari, M.S.; Pooneh Roshani Tabrizi, Ph.D.; and Tyler Salvador, B.S.) developed the hippobot — a mechanical horseback riding simulator that provides hippotherapy for children ages 4 to 10 in the office setting. To create the hippobot, the researchers mounted a carousel horse on a six-degree of freedom commercial motion platform (the platform moves in the x, y and z directions and rotates about roll, pitch and yaw axes). They then programmed the platform to simulate a horse walking, trotting and cantering.

“Several experienced horse riders have tried the motion platform and commented that it gives a realistic feel,” says Dr. Cleary.

The team then incorporated optical tracking of the hippobot rider’s spine and pelvis to monitor their posture and created a virtual reality video display that simulates a horse moving down a pier. As other animals come towards the horse, the rider must lean right or left to avoid them.  The trackers on their back show which way they are leaning and feed that information into the gaming system.

“We wanted to see how the patient’s spine reacts as the horse moves through different patterns, and if the patients get better at maintaining their posture over several sessions,” says Dr. Cleary.

To date the system has been used with several children with cerebral palsy under an IRB-approved study. All of the participants enjoyed riding the horse and came back for multiple sessions.

The hippobot system was developed in close collaboration with the Physical Medicine and Rehabilitation Division at Children’s National, including Olga Morozova, M.D., Justin Burton, M.D., and Justine Belschner, P.T.

Pedbot ankle rehabilitation system

Pedbot video game

Patients use pedbot as an input device to pilot an airplane through a series of hoops. The level of the difficulty of the game can be easily adjusted based on the patient’s capability and physical condition.

More than half of children with cerebral palsy also have gait impairment as a result of excessive plantar flexion and foot inversion/eversion, or equinovarus/equinovalgus at their ankle and foot. To help these patients, Dr. Cleary’s team developed the pedbot — a small robot platform that enables better strengthening, motor control and range of motion in the ankle joint.

“Children with cerebral palsy have difficulty walking in part because they have trouble controlling their feet,” explains Dr. Evans. “Use of pedbot as part of therapy can help to give them increased control of their feet.”

Most ankle rehabilitation robots are limited in their movements, and have only one or two degrees of freedom, focusing on ankle dorsiflexion/plantarflexion and sometimes inversion/eversion. Pedbot is unique in that it has three degrees of freedom with a remote center of motion in the ankle joint area that allows it to move in ways other devices can’t.

The pedbot platform can move in three translational directions (x, y and z) and also rotate about three axes (the x, y and z axes). As an analogy, this is similar to the movement of a flight simulator. The system also includes motors and encoders at each axis and can be used in passive and active modes.

In both modes, the patient sits on a therapy chair with their foot strapped to the robotic device. In the passive mode, the therapist assists the patient in training motions along each axis. The robot can then repeat the motion under therapist supervision while incrementally increasing the range of motion as desired by the therapist.

For the active mode or “gaming” mode, the team developed a video game based on an airplane motif. Patients use pedbot as an input device to pilot an airplane through a series of hoops. The level of the difficulty of the game can be easily adjusted based on the patient’s capability and physical condition.

To date, four patients have participated in an IRB-approved clinical trial for the pedbot. All of the patients enjoyed the game and they were willing to continue to participate as suggested by a physiotherapist.

The pedbot team, in addition to the engineers mentioned above, includes Catherine Coley, P.T.; Stacey Kovelman, P.T.; and Sara Alyamani, B.A. In future work, they plan to expand the system to include electromyography measurements with Paola Pergami, M.D.,Ph.D. They also are planning to develop a low cost, 3D printed version for the home market so children can do Pedbot therapy every day.

3D printed implant used to repair knee cartilage

/in , , , /by
Matthew Oetgen

“Our preliminary study shows this novel 3D printed material is able to allow ingrowth from the bone, so the body started to grow into the material to help fix it in place,” says Matthew Oetgen, M.D., M.B.A. “These are the first step requirements for an implant like this to be acceptable for treating lesions.”

Every year, an estimated 1 million children tear the articulate cartilage that lines their knees. Unfortunately, these types of injuries are extremely hard to repair because of the cartilage’s poor healing qualities and unique physiochemical properties.

Now, a new study by Children’s National Health System researchers has found that a three dimensional (3D) printed synthetic implant can be successfully used as a scaffold to encourage the healing and repair of articulate cartilage lesions.

Three bones meet in the knee joint: the femur, the tibia and the patella. The surface of these bones is covered with articulate cartilage, which can be damaged by injury or by normal wear and tear. Because articulate cartilage has poor healing qualities, these injuries will rarely heal or regenerate on their own, especially in younger and more active patients.

“These are active 12 to 19 year olds, so it can really affect relatively normal kids,” says Matthew Oetgen, M.D., M.B.A., Division Chief of Orthopaedic Surgery and Sports Medicine at Children’s National. “While there are many ways to repair these lesions — from implanting autogenous cells to using grafts to fill the defect — none of these options are perfect, and they all have some down sides.”

To facilitate repair of these injuries, a team of researchers led by Dr. Oetgen received a grant from the Pediatric Orthopaedic Society of North America (POSNA) to design a 3D printed implant that promotes bone and cartilage growth.

To make the implant, the team used nanoporous thermoplastic polyurethane (TPU), a biodegradable material that is highly elastic and yet strong, very much like the native cartilage in the osteochondral region. TPU is also porous, which allows blood and nutrient flow through the implant.

“The implant is designed to allow native cells to repair the lesions with normal articular cartilage and not scar tissues like some repairs,” says Dr. Oetgen.

The implant itself has a stratified structure: an upper region that contains micro channels to allow for increased perfusion; a middle zone with a nanoporous structure that mimics porous cartilage and encourages stem cell recruitment, growth and differentiation; and a lower region, or articular surface, that allows for smooth transition from the articulating surface to the implant surface and minimizes adverse interactions between the articulate cartilage and the meniscus.

When tested in vitro, the implant was able to support the growth of stem cells and vascular cells, and structurally mature vascularized bone was formed around the implant after 10 days. In animal models with full thickness osteochondral lesions the implant did just as well: The scaffold was able to promote bone, soft tissue and vascular growth without eliciting an immune response.

“Our preliminary study shows this novel 3D printed material is able to allow ingrowth from the bone, so the body started to grow into the material to help fix it in place,” says Dr. Oetgen. “These are the first step requirements for an implant like this to be acceptable for treating lesions.”

Because of the ease with which 3D printing can be scaled up, Dr. Oetgen is hopeful that the implant will one day become a viable option for repairing articulate cartilage injuries. He plans on trying the implants in a larger animal model and on larger lesions, and is also looking at custom printing for the implants to match natural lesion shapes and sizes.

Improved procedures, reduced harm: Moving the needle on spinal fusion

/in , , /by
Scoliosis X-ray image

In many cases of pediatric scoliosis, a surgical posterior spinal fusion – a life-changing yet complicated process – is needed to straighten the spine.

As part of its ongoing transition to value-based care, Children’s National is constantly reevaluating systems and processes across specialties and proactively seeking ways to deliver the highest quality care. This includes treatments for everything from the rarest of diseases to more frequent conditions, such as pediatric scoliosis.

In many cases of pediatric scoliosis, a surgical posterior spinal fusion – a life-changing yet complicated process – is needed to straighten the spine. The procedure involves permanently fusing bones over the curved part of the spine and requires expert coordination among physicians, nurses and therapists. To improve the procedure and make it as safe and efficient as possible, experts at Children’s National developed a first-of-its-kind pediatric spinal fusion surgical home, an innovative, family-centered approach that is making a real impact.

Prior to this initiative, patients who underwent posterior spinal fusion to treat scoliosis spent multiple days across multiple units in the hospital. Thanks to a comprehensive care pathway with input from all care providers treating these patients, overall recovery time has been reduced as well as days in the hospital. This in turn decreased the costs to both the families and Children’s National.

In the first six months of implementation, changes included decreasing the average length of stay from approximately five days to three and a half days, decreased blood transfusion rate and less use of opioid pain medications. Each of these pieces directly contributes to the safety of a child and decreased costs across the board. Ultimately, implementing cutting-edge practices like these brings the organization closer to zero harm and helps move the needle on patient care across the industry.

POSNA grant addresses variations in femoral fracture treatment

/in , /by
Femoral fracture

While there are plenty of options for treating pediatric femoral diaphyseal fractures, doctors don’t have a lot of specific guidance on the optimal regimen for each patient age, fracture location and fracture pattern.

Pediatric femoral diaphyseal fractures are some of the most common types of long bone fractures. There are many effective ways to treat these injuries, but unfortunately this assortment of options also leads to variations in cost and clinical outcome for patients and makes it difficult to develop clinical trials exploring the treatment of pediatric femur fractures.

To address this issue, a Children’s National research team led by Matthew Oetgen, M.D., M.B.A., Division Chief of Orthopaedic Surgery and Sports Medicine, received a $30,000 grant from the Pediatric Orthopaedic Society of North America (POSNA) to design a multi-centered, randomized, controlled clinical trial for the treatment of pediatric diaphyseal femur fractures. The team’s ultimate goal is to submit the resulting trial design to an extramural agency for study funding.

While there are plenty of options for treating pediatric femoral diaphyseal fractures, doctors don’t have a lot of specific guidance on the optimal regimen for each patient age, fracture location and fracture pattern. As a result, many treatment decisions are based on surgeon preference, regional variation in care and previous training or experience.

Another issue that arises in the treatment of diaphyseal femur fractures is the impact on the patient’s family. In general, femur fractures are caused by significant trauma that affects both the patient and the family members. On top of this, families are faced with issues such as extended hospitalization, the need for wheelchairs and walkers, pain control, missed school and secondary surgeries for removal of implants. Often, families are left to their own devices to resolve these issues, many of which are more impactful than the injury itself.

Dr. Oetgen believes that a well-planned and well-structured randomized clinical trial guided by patient and family concerns as well as expert surgical opinion has the potential to improve both treatment and care of femoral diaphyseal fracture patients.

“It is no longer good enough to design studies that only look at healing time for femur fractures,” explains Dr. Oetgen. “These injuries have such significant secondary impacts for the families of these patients, we need to determine which treatment is optimal for both fracture healing and is easiest for the families to tolerate. This grant will allow us to consider all of these outcomes in designing a study to find the best treatment for these injuries.”

To aid in the design of their clinical trial, Dr. Oetgen and his team will:

  1. Conduct an extensive literature review on the impact and treatment of pediatric femur fractures.
  2. Survey a diverse group of pediatric orthopaedic surgeons to establish areas of agreement, opposition and equipoise on the surgical treatment of pediatric femur fractures, and use that information to form a consensus opinion on the optimal design of the clinical trial.
  3. Solicit input from non-physician stakeholders (families, parents, payers, state Medicaid representatives, patient advocacy groups, professional organizations) on the important aspects of care in pediatric femur fracture treatment.

The team expects to have the study design competed by February 2019.
