Trick-or-treat – (cute) baby style

Trick-or-treat - (cute) baby style

Halloween babies

It doesn’t, in my mind, get any cuter than a baby in a Halloween costume. And 15 babies in costume? Even better! Lucile Packard Children’s Hospital encouraged participants of their Movers and Shakers and Mother-Baby Mornings classes to dress up this week, and the result is enough to make even the grumpiest of ghouls smile.

Happy Halloween!

What happens when the immune system attacks the brain? Stanford doctors investigate

What happens when the immune system attacks the brain? Stanford doctors investigate

SM PANS image - smallerThe first time he flew into a psychotic rage, Paul Michael Nelson was only 7 years old. He stabbed at a door in his family’s home with a knife, tore at blankets with his teeth, spoke in gibberish. His very worried parents, Paul and Mary Nelson, rushed him to their local emergency room, where the medical staff thought that perhaps the little boy had simply had a bad temper tantrum.

But his rages got worse. Over the weeks and months that followed the first March 2009 emergency room visit, as Paul Michael cycled in and out of psychiatric hospitals, his parents and doctors struggled to understand what was wrong. Finally, they came to a surprising conclusion: Paul Michael had an autoimmune disease. His immune system appeared to be attacking his brain.

As strange as the case seems, the Nelsons are far from alone. As I describe in a recent story for Stanford Medicine magazine, Paul Michael was the first of more than 70 children who have been evaluated at a new clinic at Lucile Packard Children’s Hospital Stanford for pediatric acute-onset neuropsychiatric syndrome, a disease (or, more likely, a group of diseases) that doctors are still working to define. The suddenness and severity of the syndrome are frightening. Healthy children abruptly begin to show psychiatric symptoms that can include severe obsessive-compulsive behavior; anorexia; intense separation anxiety at the thought of being away from a parent; deterioration in their school work, and many other problems. From my story:

“In some ways, it’s like having your kid suddenly become an Alzheimer’s patient, or like having your child revert back to being a toddler,” says Jennifer Frankovich, MD, clinical assistant professor of pediatric rheumatology at the School of Medicine and one of the clinic’s founders.

“We can’t say how many kids with psychiatric symptoms have an underlying immune or inflammatory component to their disorder, but given the burgeoning research indicating that inflammation drives mood disorders and other psychiatric problems, it’s likely to be a large subset of children and even adults diagnosed with psychiatric illnesses,” says Kiki Chang, MD, professor of psychiatry and behavioral sciences.

To shed light on the disease, Frankovich and Chang are working with scientists from around the world on defining the parameters of the illness and launching urgently-needed research. In a special issue of the Journal of Child and Adolescent Psychopharmacology that published online this month, the researchers lay out several aspects of the problem. The Stanford experts are co-authors of a scientific article describing how doctors should evaluate children with the disease, known by its acronym, PANS. Other researchers have written about disordered eating in PANS and given a detailed description of the disease phenotype.

Recognition and treatment of the disease are still an uphill battle, but the growth of research efforts is a hopeful step. As Frankovich says at the conclusion of the Stanford Medicine story, “We cannot give up on this. There are so many of these cases out there.”

Move over CRISPR, there's a new editor in town: Stanford-devised approach cures hemphilia in mice

Move over CRISPR, there's a new editor in town: Stanford-devised approach cures hemphilia in mice

A lot of attention has been paid lately to the idea of genome editing. This technique allows researchers to precisely modify an animal’s DNA to replace one version of a gene with another, or to add a working copy for a mutated gene. An approach called CRISPR/Cas9 in particular has garnered interest with its ease of use, ability to modify multiple genes, and relatively quick turnaround time when making specific strains of laboratory animals like mice for study.

Now pediatrician and geneticist Mark Kay, MD, PhD, has published  in Nature a new way to conduct genome editing that could give CRISPR a run for its money because it could be both safer and longer-lasting than other methods. As described in our press release:

The approach differs from that of other hailed techniques because it doesn’t require the co-delivery of an enzyme called an endonuclease to clip the recipient’s DNA at specific locations. It also doesn’t rely on the co-insertion of genetic “on” switches called promoters to activate the new gene’s expression.

Inclusion of endonucleases and promoters run the risk of a gamut of adverse effects in the recipient, from cancers if the promoter turns on the wrong gene in the genome to an unwanted immune response geared toward the foreign proteins. The researchers in Kay’s lab, including postdoctoral scholar and study lead author Adi Barzel, PhD, found a way around their use, and showed that it worked to enable mice with hemophilia to produce a missing blood clotting factor:

The technique devised by the researchers uses neither nucleases to cut the DNA nor a promoter to drive expression of the clotting factor gene. Instead, the researchers hitch the expression of the new gene to that of a highly expressed gene in the liver called albumin. The albumin gene makes the albumin protein, which is the most abundant protein in blood. It helps to regulate blood volume and to allow molecules that don’t easily dissolve in water to be transported in the blood.

The researchers used a modified version of a virus commonly used in gene therapy called adeno-associated virus, or AAV. In the modified version, called a viral vector, all viral genes are removed and only the therapeutic genes remain. They also relied on a biological phenomenon known as homologous recombination to insert the clotting factor gene near the albumin gene. By using a special DNA linker between the genes, the researchers were able to ensure that the clotting factor protein was made hand-in-hand with the highly expressed albumin protein.

As Kay, who is also a member of the Stanford Cancer Institute, the Stanford Child Health Research Institute and Stanford Bio X, explained, the integration of the clotting factor gene is key to the successful treatment (other clinical trials involving gene therapy for hemophilia rely on the expression of a free floating, unintegrated gene in the nucleus):

The real issue with AAV is that it’s unclear how long gene expression will last when the gene is not integrated into the genome. Infants and children, who would benefit most from treatment, are still growing, and an unintegrated gene could lose its effectiveness because it’s not copied from cell to cell. Furthermore, it’s not possible to re-administer the treatment because patients develop an immune response to AAV. But with integration we could get lifelong expression without fear of cancers or other DNA damage.

Parents can learn autism therapy in groups to improve kids' verbal skills, Stanford study shows

Parents can learn autism therapy in groups to improve kids' verbal skills, Stanford study shows

HoldingHandsAutism is more than twice as common than it was 15 years ago. But the number of clinicians who treat the developmental disorder is growing more slowly than the number of new cases, prompting caregivers to look for novel ways to share their expertise as widely as possible.

One possible approach: Teach groups of parents an autism therapy they can deliver at home. A new study from Stanford and Lucile Packard Children’s Hospital Stanford, published today in the Journal of Child Psychology and Psychiatry, found that small groups of parents could learn to deliver a scientifically validated autism treatment to their own children in a short series of classes.

The therapy, called pivotal response training, which has been validated in several prior studies, was targeted to kids’ language skills. The therapy gives parents a structured method for nurturing children’s verbal skills during everyday interactions.

The approach of having parents give treatment is meant to complement, not replace, one-on-one therapy with autism professionals. But it can still be valuable to children and their families, as our press release explains:

“There are two benefits: The child can make progress, and the parents leave the treatment program better equipped to facilitate the child’s development over the course of their daily routines,” said study co-author Grace Gengoux, PhD, clinical assistant professor of psychiatry and behavioral sciences and a psychologist specializing in autism treatment at the hospital. “The ways that parents instinctually interact with children to guide language development may not work for a child with autism, which can frustrate parents. Other studies have shown that learning this treatment reduces parents’ stress and improves their happiness. Parents benefit from knowing how to help their children learn.”

… To use the treatment for building language skills, parents identify something the child wants and systematically reward the child for trying to talk about it. For instance, if the child reaches for a ball, the parent says, “Do you want the ball? Say ‘ball.’”

“The child might say ‘ba,’ and you reward him by giving him the ball,” [lead author Antonio] Hardan, MD, said. “Parents can create opportunities for this treatment to work at the dinner table, in the park, in the car, while they’re out for a walk.”

The researchers are now following up with studies that will give them more information about which children and families are most likely to benefit from this therapeutic approach.

A few years ago, I was doing a summer internship in which I looked at health outcomes for hospitalized patients. I sat in an office and read about patients with issues like high blood pressure and cholesterol. At a certain point, I realized that the reports on their outcomes were interesting, but the real solution to the problems I was studying was happening outside my window. My window overlooked a park, where kids would run around all day until they were exhausted. And it got me thinking that if all kids were as active as those ones, there would a lot fewer reports for me to read.

So last year, I worked with several medical and law students to design a county-level childhood obesity prevention policy. The need for such programs is self-explanatory: More than one third of children in the U.S. are overweight or obese. By the time people reach adulthood, that proportion goes up to two thirds. By creating a team of both medical and law students, we hoped to come up with approaches that achieved the goal of improving health, and did so in a practical and implementable way.

Over the course of several months, we analyzed dozens of programs that have been used to bring down childhood obesity rates in various communities across the country. The programs ranged from well-known approaches (e.g. a soda tax or menu calorie counts) to some more obscure ones. My personal favorite was the “Walking School Bus” (WSB). Think about how your parents used to tell you that things were tougher in their day when they had to walk to school (in the snow, going uphill, barefoot, etc.). The goal of a WSB is to bring that world back. The catch is that parents/adults walk along a predetermined “bus” route, pick up kids along the way, and then walk them to school. Kids get a supervised walk that allows them to get some exercise every day.

Case studies, and one meta-analysis, suggest that WSBs are an effective way to increase the amount of exercise kids get. But odds are, you’ve never heard about them before. Neither have most school officials, local politicians, and others in a position to take action on childhood obesity. That’s because WSBs are not widely used. This realization led me to an interesting question: Which factors make a local program or intervention spread to other communities? What does it take to turn a single success story into a widespread strategy?

These are hardly new questions. Every business or non-profit that plans to scale up considers it. Atul Gawande, MD, attempted to figure out why certain medical interventions spread in a New Yorker article last year. Whether you’re talking about social programs, technology, or just an idea, the question remains. I don’t pretend to have the answer, but my work reviewing obesity prevention policies did lead me to a few conclusions about the spread of local programs.

First, success is necessary but not sufficient for a program’s spread. Just because it proves to be successful does not mean anyone else will adopt it. WSBs were one example. Granted, WSBs are not adaptable to every community – they require schools to be within walking distance and rely on good weather. But the same story is true for other approaches. For instance, joint-use agreements are a strategy where schools open up their facilities (e.g. outdoor fields, basketball courts, etc.) after school hours to give children and families access to recreational space. Despite a correlation between these agreements and better health outcomes, they remain in limited use in many of the communities where recreational space is most lacking.

So if success doesn’t lead to a program’s spread, what does? I believe one factor is the involvement and enthusiasm of multiple stakeholders, potentially including local government, businesses, school administrators, and involved community members. A second factor is the development of measurable and achievable goals. It is nearly impossible to see incremental changes in health outcomes, so programs designed to change health must establish metrics that can demonstrate progress.

The list of lessons from our survey of local programs goes on, but the biggest takeaway is clear. Problems in health care require not only a solution, but successful execution.

Ivy and Bean help encourage kids to get vaccinated

Ivy and Bean help encourage kids to get vaccinated

Ivy and Bean2Last week, I took my two little boys to get their shots, including the MMR vaccine that protects against measles, mumps and rubella. Although, as a mom, it’s easy for me to understand the value of vaccines, I’m not sure my preschooler was completely convinced that getting poked in the arm was a great idea.

That’s why I am thrilled to see “Ivy and Bean vs. The Measles,” a set of posters and other educational materials that Sophie Blackall, the illustrator of the popular series of children’s books, has produced in collaboration with the Measles and Rubella Initiative. Blackall’s illustrations show Bean, one of the book’s two heroines, devising a series of unconventional strategies for avoiding the measles: wear a biohazard suit for the rest of your life, get adopted by a polar bear, or (my personal favorite) cover yourself in a 6-inch protective layer of lard.

“Or,” says Ivy, “get vaccinated!”

My son would probably be most interested in Bean’s suggestion to “Move to the moon!” He loves all things outer space-related, and I love the idea of finding something at our doctor’s office that would spark his interest and help me explain to him why he needs that brief poke in the arm.

Bravo, Ivy and Bean!

Summer’s child: Stanford researchers use season of birth to estimate cancer risk

Summer’s child: Stanford researchers use season of birth to estimate cancer risk

Four_seasons

One of the hardest parts of unraveling childhood cancers is understanding what causes them. In recent years, evidence has been mounting that cancer and many other chronic diseases begin early in life – and perhaps even in utero. To untangle some of these early causes of cancer in children and young adults, Stanford epidemiologist and family physician Casey Crump, MD, PhD, is partnering with researchers at Lund University in Sweden, a working relationship was set up by Marilyn Winkleby, PhD, MPH, professor emeritus of medicine here. The team is using Sweden’s national registries for birth certificates and medical records to track how factors during gestation and soon after birth – called perinatal factors – affect cancer risks.

Because Sweden has a national health care system, it’s relatively easy to track the course of illness in individuals. By comparison, the U.S.’s health care system is fragmented across dozens of health care providers and insurers, so getting medical records for a single person that might span decades is a much more difficult prospect.

Crump’s team is focusing on cancers that are common in childhood and early adulthood: brain tumors, leukemia and lymphoma among them. Two papers published earlier this year examine how the time of year a child is born affects cancer risk. The most recent, published ahead of print in April in the International Journal of Cancer, examined whether the season of birth was linked to the risk of developing either Hodgkin’s lymphoma or non-Hodgkin’s lymphoma later in life. Crump explained:

Lymphomas are among the most common cancers in childhood but the causes are still largely unknown. It’s been hypothesized that infectious exposures, such as Epstein Barr virus and others may play an important role, but it’s still unclear what the critical age window of susceptibility might be. We had an opportunity to use season of birth from birth records as a proxy for infectious exposures in the first few months of life, and see the relationship between that and subsequent risk of Hodgkin’s and non-Hodgkin’s lymphoma – following these people from birth through childhood and on into young adulthood.

The researchers found that children born in spring or summer had a higher risk of developing non-Hodgkin’s lymphoma later in life compared to kids born in winter. The team didn’t find any similar seasonal pattern for risk of Hodgkin’s lymphoma. The results lend additional support to the “delayed exposure hypothesis.” Children born in spring or summer may not be exposed to critical pathogens during a critical early period of immune system development, leaving them vulnerable later in life. Children born in the fall or winter, by comparison, do get that important exposure at just the right time. Crump was quick to note that season of birth provides only a rough estimate of these exposures, since the team didn’t have accurate measures of exposures to Epstein Barr or other viruses, but he also added that these results “shed additional light on possible pathways of risk that may contribute to the development of non-Hodgkin’s lymphoma.”

A similar study published in January in the International Journal of Epidemiology found that children born in spring and summer had a higher chance of developing melanoma later in childhood or early adulthood. The team hypothesized that spring and summer babies are exposed to more UV radiation in warm summer months in the first few months of life – an exposure that fall and winter babies are less likely to have.

Families can help their teens recover from anorexia, new study shows

Families can help their teens recover from anorexia, new study shows

anorexia-appleUpdated 10-2-14: In a just-published 1:2:1 podcast, Lock discusses this work in depth.

***

9-24-14: A large new study comparing two treatments for anorexia nervosa offers a hopeful message to parents of teens affected by the eating disorder: Families can work with therapists to help their children recover.

The study, which appears today in JAMA Psychiatry and was led by Stanford’s Stewart Agras, MD, was the first large randomized clinical trial to compare two forms of family-based treatment for anorexia. The study included 167 anorexia patients, aged 12 to 18, at six medical centers in the United States and Canada.

In both treatments tested, a trained therapist met regularly with the patient and at least one other member of his or her family. One type of therapy focused on teaching parents how to get their child eating again at home, a method that Agras and Stanford eating disorder expert James Lock, MD, PhD, have researched extensively in the past. The other approach was broader, with the therapist and the family exploring problems in family dynamics and how to solve them. Patients and families in both treatment groups received 16 one-hour therapy sessions over a nine-month period, and patients’ recovery was assessed at the end of the therapy and again one year later.

Both therapies were equally effective in the long run, but the approach that focused on feeding was faster, and patients in that group were hospitalized fewer days during their treatment, which also made this method less expensive. The findings add to a growing list of scientific studies that are changing how physicians think about the families of patients with eating disorders, as our press release explains:

“For a long time, people blamed families for causing anorexia and thought they should be left out of treatment,” said Lock. “But this study suggests that, however you involve them, families can be useful, and that more focused family treatment works faster and more cost-effectively for most patients.” Lock directs the Comprehensive Eating Disorders Program at Lucile Packard Children’s Hospital Stanford.

The need for good treatments for anorexia in teens is bolstered by prior research demonstrating that the disease becomes more difficult to treat in adulthood, as Agras noted:

“The longer anorexia goes on, the more difficult it is to treat,” he said. “A great many people live chronically restricted lives because of this disease — they plan their days around undereating and overexercise — and quite a few die. The idea is to treat the disorder in adolescence to prevent more adults from becoming anorexic.”

Lock is the c0-author of the book Help Your Teenager Beat an Eating Disorder, which is designed to help parents conduct the feeding-based treatment examined in this study. Lock and Agras have both contributed to textbooks and manuals on eating disorder treatment for health care professionals.

The promise and peril of genome sequencing newborns

NICUEven though doctors and researchers have made great strides in caring for patients in the past few decades, there are still many illnesses that are difficult to diagnose, let alone treat. Among the most heartbreaking cases are those newborns who come down with mysterious illnesses that defy medical expertise. But in recent years, doctors have turned to genetic sequencing in some of these cases to identify the culprit causes of the illnesses.

Last year, the National Institutes of Health funded four pilot projects looking into the efficacy and ethics of genetic screening for otherwise inexplicable illnesses in newborns. The first of the trials will begin next week at Children’s Mercy Hospital in Kansas City, Missouri, as reported in a recent story from Nature. The trial at Children’s Mercy Hospital will focus on rapid genome sequencing with a 24-hour turn-around. Genetic sequencing normally takes weeks, but some of these infants don’t survive that long. Doctors have used similar rapid genome sequencing to diagnose an infant with cardiac defects at Lucile Packard Children’s Hospital Stanford.

Earlier this year, I had the opportunity to report on a rare genetic mutation that leads young infants to develop inflammatory bowel disease. I spoke with some parents of children with the mutation, which was identified by sequencing the children’s exome – just the protein-producing part of the genome – as part of a new project (separate from the NIH trials) at the University of Toronto in Canada. As I explain in the piece, getting a bone marrow transplant early enough can help alleviate symptoms and save the child’s life.

The parents were uniformly grateful for the sequencing technology that made it possible to understand what was causing their baby’s illness, even in cases where the child didn’t survive long after diagnosis. One mother mentioned that realizing some of the best doctors in the country didn’t know what was ailing her daughter made the experience even more frightening. After months of worried confusion about their young children’s deteriorating health, for these parents to have an answer was a relief.

But because the technique is so new, several ethical details still need clarification – which the NIH study hopes to answer. From the Nature news story:

Misha Angrist, a genomic-policy expert at Duke University in Durham, North Carolina, says that although the 24-hour genome process is impressive, it is not clear whether genomic sequencing of newborns will soon become standard practice. Many questions remain about who will pay for sequencing, who should have access to the data and how far clinicians should go in extracting genome information that is unrelated to the disease at hand. Then there is the question of how informative the process is. “I think it’s really important that we do these experiments so that we start to see what that yield is,” Angrist says.

All four teams will include an ethicist who will be responsible for dealing with questions like the ones Angrist raises. The other three trials at Boston Children’s Hospital, the University of North Carolina in Chapel Hill, and at the University of California, San Francisco are still awaiting approval from the Federal Drug Adminstration.

Stanford experts offer more information about enterovirus-D68

Stanford experts offer more information about enterovirus-D68

Below is an updated version of an entry that was originally posted on Sept. 26.

SONY DSCLast week, the California Department of Public Health confirmed that the season’s first four cases of enterovirus-D68 respiratory illness had been found in the state, three in San Diego County and one in Ventura County, with more expected to surface. As of Sept. 29, this makes California one of 40 states across the nation to be affected by EV-D68.

Health officials in Colorado are now investigating a handful of cases of paralysis in children there; the paralysis began a few weeks after respiratory illness and appears to be connected to EV-D68. Since the same virus was tentatively linked to paralysis cases in California children earlier this year, California officials are monitoring the situation closely.

Below, Yvonne Maldonado, MD, service chief of pediatric infectious disease at Lucile Packard Children’s Hospital Stanford, answers additional questions about the respiratory symptoms caused by this virus. Keith Van Haren, MD, a pediatric neurologist who has been assisting closely with the California Department of Public Health’s investigation, also comments on neurologic symptoms that might be associated with the virus.

Enteroviruses are not unusual. Why is there so much focus from health officials on this one, EV-D68?

Maldonado: The good news is that this virus comes from a very common family of viruses that cause most fever-producing illnesses in childhood. But it’s been more severe than other enteroviruses. Some hospitals in other parts of the country have had hundreds of children coming to their emergency departments with really bad respiratory symptoms. The fact that it’s been so highly symptomatic and that there has been a large volume of cases is why it has gotten so much attention.

Van Haren: It’s important to remember that most children and adults who are exposed to enteroviruses don’t get sick at all. A smaller percentage come down with fever and/or respiratory symptoms, as Dr. Maldonado has described. And as far as we can tell, it’s only a very, very small number of children, if any, who get paralysis, typically affecting one arm or leg. The Centers for Disease Control and the California Department of Public Health are still investigating to try to determine conclusively whether EV-D68 is causing neurologic symptoms, such as paralysis.

What do we know about the course of possible neurologic symptoms of EV-D68 and their potential treatments?

Van Haren: We’re still learning about the possible neurologic symptoms and how we might treat them. To start, we have a growing suspicion that EV-D68 may be associated with paralysis. In the patients we’ve seen with paralysis, progression of weakness appears to stop on its own, and recovery of strength is very slow and usually incomplete.

Which groups are most at risk?

Maldonado: Children with a history of asthma have been reported to have especially bad respiratory symptoms with this virus. It can affect kids of all ages, from infants to teens. So far, only one case has been reported in an adult, which makes sense because adults are more likely to have immunity to enteroviruses. We do worry more about young infants than older children, just because they probably haven’t seen the virus before and can get worse respiratory symptoms with these viral infections.

Van Haren: We don’t yet know who is most at risk for paralysis or other neurologic symptoms, but we are studying this carefully to find out why some children get sick and some do not. So far, it seems that the children who have been affected by paralysis were generally healthy prior to their illness.

What is the treatment for EV-D68?

Maldonado: There is no treatment that is specific to the virus. At home, parents can manage children’s fevers with over-the-counter medications, make sure they drink lots of fluids to avoid dehydration, and help them get plenty of rest. For children who are very ill, doctors will check for secondary illnesses such as bacterial pneumonia, which would be treated with antibiotics, and may hospitalize children who need oxygen or IV hydration to help them recover.
