RETT SYNDROME RESEARCH TRUST WEBSITE
GERMAN TRANSLATION
[SPANISH] Escoliosis en Síndrome de Rett
This blog post will deviate from our typical scientific pieces to focus on a clinical aspect of Rett: scoliosis. As a mother, I can testify that the mere thought of scoliosis surgery makes my knees weak and my stomach queasy. I’ve spoken to enough parents during the past decade to know I’m not alone in these emotions. My hope is to engage families and their network of doctors, therapists and educators in a dialogue about the potential treatment and – even better – the prevention of scoliosis in Rett Syndrome.
My daughter with Rett is 13 years old, and she is on the severe end of the spectrum. One area in which we’ve had some success is orthopedics. We’ve managed to improve her scoliosis through an intense program of physical therapy (PT), massage, chiropractic and cranio-sacral work.
Below are excerpts from a conversation with Dr. Vishal Sarwahi, the Director of the Spine Deformity Service and a team member of the Rett Syndrome Center at Children’s Hospital at Montefiore, in the Bronx, NY, run by Dr. Sasha Djukic.
MC: I think of Rett as exerting its power over our children 24 hours a day. One way to fight back the physical challenges Rett imposes is through therapies. One hour a day of impactful physical therapy brings the score, so to speak, to Rett 23, Child 1. Each time my daughter visits her therapist she goes in with a slight curve and comes out straight. It’s a constant battle. Rett pulls her one way, we pull her the other. The key is to fight that battle each day or you lose ground.
So one thing I would like to share with parents and get them thinking about is an intensity level that may be crucial. Without evidence-based research, which is currently lacking, proving that intensity is important is very difficult. Families are left to negotiate with their schools and their insurance companies.
VS: You are right. There is no clear scientific evidence that physical therapy can alter the natural history of scoliosis. If parents ask me if physical therapy helps – the answer is a resounding YES. But is there any scientific evidence that it will change the natural history of scoliosis? The answer is NO – because, to date, there are no published studies. Personally I am confident that PT, if done properly by a good therapist, and as you say, for an appropriate amount of time, is very helpful. But it’s difficult to put a number to the required hours. I would say perhaps an hour per day to work on various forms of activities to condition the back and keep it strong, and not just the back but the abdominal muscles as well.
Your own daughter, who does not walk independently, is a great example because scoliosis tends to happen more commonly in kids who do not ambulate. And the fact that she has been through growth spurts without having major changes in her back is key. The problem is scientifically proving that it’s the PT that is responsible. How do we know whether she is in the small percentage of cases that have very minor scoliosis?
MC: Actually, her scoliosis has gotten better. How many kids with Rett have curves that get better?
VS: Very few
PANCREATITIS
MC: Can you talk a little bit about pancreatitis and the increased risk after surgery that parents should be aware of? This is one of several concerns about which parents can take a proactive stance, if they are well-informed.
VS: Yes, individuals who undergo scoliosis surgery have a higher risk of pancreatitis. There are some studies which show that the risk is even higher in kids with neuromuscular disorders. It’s very difficult to understand why they get pancreatitis – there are multiple theories. One theory is that maybe the morphine they get for pain shuts down the sphincter and there’s some regurgitation of juices back into the pancreas, causing a chemical pancreatitis. It usually presents in the first week after surgery and can affect between 15 – 30% of patients. In our center we don’t see it as frequently, our percentages range from 10-15% perhaps because we follow a much stricter protocol than most, including routinely checking pancreatic enzyme levels. In nonverbal children we palpate the belly and if the heart rate goes up that suggests the child is in discomfort or pain. If the enzymes are on the higher side we can do an ultrasound to rule it out. The treatment is no food by mouth until the enzymes resolve. Bottom line, pancreatitis in the nonverbal patients is something we have to look for. If the parents are aware, if the physicians are aware, if the surgical team is aware then it’s more likely that it can be diagnosed sooner. Not sure we can say that it can be avoided, but it can be diagnosed sooner and at least be taken care of, because the complications sometimes are severe.
MC: Pain medications are another issue that I find very concerning. There are publications that say that children with Rett Syndrome have great tolerance for pain. I’m not always sure that their pain is properly cared for after surgery. My personal hypothesis is that they feel pain just like the rest of us but they don’t express it the way we would expect them to react to pain. And so I sometimes think the interpretation is that they don’t feel pain or they have a high pain threshold. And I’m not sure that’s it at all.
VS: So this is a topic very close to my heart, actually. It’s very difficult for us to gauge pain. First, I always trust the parent. One thing I teach my residents is that the mother knows best. If the mother says the child is in pain then the child is in pain. But even a mother sometimes has difficulty gauging pain levels. So we look at the blood pressure and heart rate. Shallow breathing can often mean pain. And at the Rett center we also take into consideration that children with Rett can have a very irregular breathing pattern.
MC: What about seizures? I mean how often would you expect to see a child having seizures after surgery as this can be very jarring to the body.
VS: Of course, the neurologist has to be on board and part of the team. And much depends on the fixation that has been used. For our children, seizures—or even if a child were to take a tumble—should not cause damage per se. I don’t brace any of my children after surgery, or use casts.
ALLERGIC REACTIONS
MC: Another area of concern for Rett Syndrome patients, some of whom have mitochondrial and other issues, is the type of anesthesia. So what kind of background work is done to determine what kind of anesthesia is going to be used?
VS: Our approach to anesthesia is always multidisciplinary. We go over the precautions and contraindications. At our center we actually have two anesthesiologists, and a pediatric anesthesiologist is always involved in the scoliosis surgeries.
MC: I understand at Montefiore you routinely test for metal allergies before surgeries. I can’t imagine anything more horrific than to put all of the hardware in and then have to take it all out due to an allergic reaction. I know from speaking with parents that most Rett patients are not tested for this prior to surgery. My own daughter has never worn jewelry or belt buckles, so the possibility of allergies naturally coming to light may be slim.
VS: Typically an allergy to metal has a very slow onset. It’s not like anaphylaxis where you see it right away. Nevertheless we have decided to routinely test although it’s expensive and time consuming. Better to be safe.
MC: Congratulations to your center for taking a precautionary approach, and I hope this will become more widespread. At least our readers are now armed with the knowledge to ask for this testing if it is not offered as a matter of course.
LOOKING AHEAD
MC: Now for more of a research question… Where do you see the science moving? I mean do you think that eventually these types of scoliosis that are neuromuscular, neurogenic in nature, do you think they will be preventable at some point or treatable in such a way that surgery will no longer be necessary?
VS: Well, my hope is yes. As of now, a gene for idiopathic scoliosis, which is the most common scoliosis and not the neuromuscular type, has been identified. Whether that is the only gene, and how that gene expresses itself, is still unknown. For neuromuscular scoliosis it’s unclear if there’s a specific scoliosis gene that is causing it. And in Rett Syndrome, is it a gene directly associated with MECP2 or is the scoliosis secondary to a neuromuscular imbalance? It may be the latter. My fervent hope is once again that we figure out how to fix that.
MC: Do you think that there should be more exploration, beyond PT or bracing, to help correct this imbalance, along the lines perhaps of the use of Botox?
VS: Well I do find it difficult to accept the philosophy that scoliosis in Rett Syndrome is inevitable. I find there’s this philosophy every child is doomed to have it and there’s very little to do. If parents and doctors believe that you fall into a vicious cycle and there’s not enough focus on innovative strategies.
MC: I agree with you. In general, the literature about Rett talks about these four stages, and the motor degeneration at the fourth stage. I can’t help but think that what may be contributing to this degeneration is that the children are growing bigger and heavier, they aren’t receiving the same level of services that were available when they were younger through the schools and other programs, and the parents are getting older and more tired, So there’s an overall reduction in resources and therapies, fewer therapists involved, and we have to wonder how much degeneration is due to the disease itself and the natural progression, and how much is due to external circumstances.
VS: There’s always the question of nature versus nurture in Rett, and it may be that with optimal and very individualized services for each child and adult, there is much more wiggle room, more variation and chance for solid improvement than the Rett community as a whole has had the opportunity to fully explore and document. But I think this type of discussion is interesting; it raises awareness and challenges us to do better.
MC: Thank you, Dr Sarwahi, for your time and the care with which you address these issues. I hope we can continue to dialogue as we look toward new and innovative approaches.

Regular Chiropractic Adjustments & Physical Therapy together can prevent or slow the process of Scoliosis. My daughter, Isabella, is 6 years old. She has had chiropractic adjustments 3 x per week since she was 3 years old when she was diagnosed incorrectly as Autistic. Her spine is perfectly straight, she walks, runs, jumps and her balance and coordination is excellent. Thankfully, I started the adjustments then because a year and a half later she was diagnosed with Rett Syndrome. It was the best thing I ever did for her.
Go to the http://scoliosissystems.com to read more about Chiropractic Care for Scoliosis and Wellness. If you are in the North Jersey, NYC area, I have a wonderful Chiropractic practice that I can refer you to. It is not only good for scoliosis or pain, but also for overall health, immune system, central nervous system and may also help with digestive problems. It is worth a try because anything is better than putting our Angels under the knife. Hope this helps.

Hi Monica–Abby, just 13 in Feb., had surgery for her scoliosis last Aug, at age 12 1/2. She is quite ambulatory–in fact, rarely sits down. Her curve had been stable at 19 degrees from age 4 until age 9 1/2; at age 10 it jumped to 33 degrees. We were able to hold the curve there for a year, and perhaps even reduced it by a degree or two, with more PT, including a “positioning program” we read about–a paper by a doctor in Israel, who said he temporarily reversed a curve in a girl with rett. It involved placing blocks under one side of the chair, to force the girl to lean away from the curve, plus lying across bolsters to stretch the shortened side, etc. We were pleased with the efforts. However, the next growth spurt took it’s toll, and the spine began to collapse rapidly, and added a twist to boot. By the time she was 12, and we were scheduling surgery, the curve was approaching 70. And this in a girl who ran, walked, jumped, climbed, swam, and used a seating system when she DID sit down. We were fortunate to find a surgeon at Dupont Hospital in Delaware who was quite experienced with girls with rett. He told us, among, other things, that he did not brace girls with rett, that he was comfortable doing surgery at a younger age than some–as long as the lungs are fully developed–because he can get a better correction on a more flexible spine, and that he kept the girls in the ICU, and in the hospital a bit longer than some do precisely because he found that they are unusually susceptible to pancreatitis, and he wants to watch for that. Our hospital experience was very long–an allergic reaction (not to the metal!) caused the surgery to be aborted about 6 hours into it. It was resumed 9 days later, but she lost a lot of weight, got pneumonia, etc.–all things you would expect from a prolonged hospital stay. However–the end result is a zero curve. She can do everything she could before, except bend at the waist. She can crawl, ride a bike, use a treadmill, walk fast enough to get away from me, climb stairs, get up and down off the floor, pick something up from the floor, (as long as it’s something her hand use permits her to pick up, that is! The back is no problem) She even still has a “small of the back” curve–he crimped the rods to make the back natural, not flat. She can sit on the floor with her legs out in front of her and not fall backwards. Her PT’s all say they’ve never seen anyone–disabled or otherwise–with this degree of mobility after the surgery. She gained back the 12 pounds she lost, plus 7 more. Her appetite has improved, as has her digestion. I would have done just about anything to avoid that surgery! But we are so very pleased with the results. Abby is much, much more comfortable. To anyone facing this, I would suggest that you find a surgeon who knows rett syndrome well. I think it makes a big difference.

Thanks for the blog interview and thanks to Carla for the chiropractic site, which has a link about scoliosis and vestibular issues that I find interesting.
