Science is under attack, and not just from anti-vaccine celebrities and parents with degrees from Google University. Scientific illiteracy is being woven into the very fabric of our society through legislative assault. If you dismiss this as alarmist hyperbole, you haven’t been paying close enough attention.
Every day thousands of pediatric health care providers throughout the country provide safety advice to patients and their parents during routine health maintenance visits. As part of this important routine we ask a series of standard questions to assess the safety of our patients’ environment. Some of these questions are easy and straightforward, and some are more personal and potentially awkward for patients and their parents, including questions pertaining to sexual practices and preferences and psychosocial history. An important series of questions focuses on potential hazards in the home, such as how toxins and medicines are stored, how pools are secured against curious toddlers, and whether there are guns in the home and how they are stored and secured. Parents are usually appreciative of the advice we provide, and thankful for our concern and attention to these issues. Occasionally patients or parents are taken aback by some of these questions, and very rarely they prefer not to answer them (in my 20 years in practice, I can recall only one time this has occurred). We ask these questions because accidental injuries and deaths are common occurrences in the pediatric population, and there is good evidence that patients tend to follow the advice we provide our patients.

It’s that time of year when every day I can expect to see at least one patient with a concern about Lyme disease. In Lyme-endemic regions such as Western Massachusetts, where I practice pediatrics, summer brings a steady stream of children to my office with either the classic Lyme rash (erythema chronicum migrans, or ECM), an embedded tick, a history of a tick bite, or non-specific signs or symptoms that may or may not be due to Lyme disease. Sometimes the diagnosis is relatively straightforward. A child is brought in after a parent has pulled off an engorged deer tick, and there is a classic, enlarging ECM rash at the site of the bite. More often the presentation is less clear, requiring detective work and science-based reasoning to make an informed decision and a diagnostic and therapeutic plan based on the best available evidence. Depending on the story, the plan may include immediate treatment without any testing (as in the straightforward case described above), immediate testing without treatment pending test results, or waiting as we watch and see how a rash progresses before doing anything. An example of this latter course of action would be when a patient comes in with a pink swelling at the site of a new tick bite. In this case, it may not be clear if the swelling is a Lyme rash or simply a local reaction to the bite, a much more common occurrence. The classic ECM rash (an enlarging, red, circular, bull’s-eye rash at or near a tick bite) typically develops 1-2 weeks after a tick bite, but can occur anywhere from 3-30 days later. It then expands and darkens over another 1-3 weeks before fading. This classic rash is not the most common rash of Lyme disease, however, as it occurs in only about 30% of cases. Instead, the rash may be uniformly pink or red (or even darker in the center) without the target-like appearance, or may be a linear rash, expanding outward from the tick bite site. In the case of a patient who comes in with a vague, pink swelling within a day few days of a tick bite, we will typically wait and see what happens to the rash. If it is a local reaction, it will likely resolve within another few days. With Lyme disease, the rash will continue to enlarge and declare itself as an ECM rash. Another unclear and not uncommon situation is when a patient comes in with non-specific symptoms such as fatigue, musculoskeletal pains, and headache. If warranted by the history and the physical exam, we may in this case order Lyme testing. This may not give us an answer even if the patient has Lyme disease, because results are often negative in the first few weeks of the disease. In this case, if symptoms persist or evolve, we will repeat the testing in another few weeks at which point true Lyme disease will test positive and can then be treated. The good news is that the treatment of Lyme disease, particularly in the early, localized phase of the disease, is extremely safe and effective with a 14-day course of antibiotics. The testing is also relatively straightforward, with very good sensitivity and specificity when performed correctly. And this is where the bad news comes… (more…)
I know by now I shouldn’t be, but I am still amazed by how readily so many people buy into the seemingly endless array of bogus sCAM nostrums. Many are marketed and hawked for the treatment or prevention of diseases that are poorly managed by science-based medicine. There are countless examples of dietary supplements that are purported to effectively treat back and joint pains, depression, anxiety, autism, chronic pain, and chronic fatigue; the list goes on and on. The lure for these treatments is at least understandable and, although frustrated that scientific literacy and rational thought loses out, I empathize with the desire to believe in them. On the other end of the spectrum is the even more ethically corrupt substitution of safe and effective treatments with products that are not. I encountered what I find to be possibly the most frightening and dangerous example of this recently at my practice. A family new to the area called to schedule a routine health-maintenance visit for their 5-year-old daughter. When our nurse reviewed the medical records the mother had faxed over, she noted that the child was unimmunized and explained to her that she would need to begin catch-up vaccinations. The mother matter-of-factly stated that her daughter was actually fully vaccinated with a vaccine alternative. She had received a series of homeopathic vaccines from a naturopath. I am not going to discuss this egregious example of sCAM here, though it was addressed in previous SBM posts.1,2 Instead I’d like to focus on another part of the sCAM spectrum. Here lies a form of sCAM that, in some ways, is even more difficult for me to comprehend. These are products invented, marketed, and sold solely for the treatment or prevention of fictitious diseases or problems that exist only in the realm of fantasy. (more…)
As a pediatrician I have an opportunity to observe a wide variety of unusual and sometimes alarming parental efforts meant to help children through illness or keep them well. I have recently noticed one particular intervention that seems to be becoming more prevalent, at least in my practice. I’ve begun to see more and more infants sporting Baltic amber teething necklaces. These consist of multiple small beads of amber on a string that is worn around a baby’s neck, and are supposed to relieve the discomfort of teething. Before I had any idea what these necklaces were for or how they were supposed to work, my first reaction was to inform these parents of the dangers of necklaces or anything placed around an infant’s or young child’s neck. Strangulation is a known cause of accidental injury and death in children, and pediatricians are trained to discuss this as part of the routine anticipatory guidance we give to parents. In addition, we strongly advise against giving infants or young children any small items that could be accidentally aspirated, such as the beads found in a necklace of this sort. But I was equally surprised to learn that these necklaces are not intended for babies to chew or gum. Instead, they are supposed to ease a baby’s teething discomfort simply by lying against the skin.
I will not discuss teething here, or the many myths that surround it; that was well covered in a previous post. I will reiterate that there is little-to-no evidence that the majority of concerns parents have about teething are actually due to teething, including fever and diarrhea. The irritability associated with teething also tends to wax and wane for only several days before and after the emergence of a tooth. But let’s assume for the moment that these necklaces actually work to ease the discomfort of teething, and whatever other problems parents tend to associate with the long period of time during which infants and young children develop their teeth. Assuming these necklaces work as recounted in the glowing testimonials on countless websites and parent blogs, how do they produce their dramatic results?

For those of us dedicated to supporting science-based medicine and fighting the ever-widening reach of sCAM, pseudoscience, and health fraud, finding a new woo-filled claim or a dangerous, evidence-lacking trend to write about is relatively easy. Many of us may not realize, however, that some of the most commonly used and recommended treatments, one of which at least is probably sitting in your medicine cabinet as you read this, is equally devoid of evidence to support its use.
Every drug store has row upon row of medicines designed to treat or prevent an acute upper respiratory tract infection, otherwise known as the common cold. Despite this, very few are able to live up to their promise. In most cases, particularly where children are concerned, the side effects of these medicines can be worse than the symptoms they are intended to treat. Because I am a pediatrician, and because the evidence for cough and cold medicines (I will refer to them here as CCMs) for children is particularly absent and because adverse events due to CCMs are most frequently seen in children, I will focus mainly on this population.

Back in 2009 I wrote a story entitled, “The New Plague”, about my experiences as a pediatrician with the frightening trend of parental vaccine refusal in New York City. In that post I discussed some of the complex social factors contributing to this phenomenon, and some of the common vaccine myths to which many parents fall prey. I recommend that you read that post, as it is (unfortunately) as timely today as it was then. Now I’m a pediatrician in Amherst, Massachusetts, and I find it necessary to revisit this dangerous trend in parenting.
As I described in my previous post on the subject, my old practice was at an interesting crossroads of several communities that seemed to perfectly embody the socioeconomic and cultural characteristics commonly found in communities with high rates of parental vaccine refusal. Ironically, these tend to include people who are educated and socially privileged; those empowered to question authority. In 2010, I left New York City and moved to Western Massachusetts to take a job at Baystate Children’s Hospital in Springfield. There I was in charge of the teaching clinic where pediatric residents are trained in the outpatient care of children. The children we took care of in Springfield comprised a very high-risk, underprivileged population. Our patients were significantly below the poverty level, with high rates of developmental and educational disability, a high teen pregnancy rate, and high rates of domestic violence, drug use, and gang involvement. Children who were not up to date with their vaccinations were behind because of poor continuity of care, with many missed appointments and gaps in follow-up. I now work at a private practice further north in the Pioneer Valley of Central Massachusetts. Here, my experiences with vaccine lapses are starkly different. Now, when I encounter a child who is not fully vaccinated or is completely unvaccinated, it is the result of a parental decision. A very flawed, dangerous, and misinformed parental decision.
It’s summertime, and the living is easy. Forget the solstice. For most of North America, this week is the real start of summer – July 1 in Canada, and July 4 in the USA. Vacation time means breaking out of that those usual routines of work and school. I’m amazed after a few weeks of vacation how much sleep my body will accept if given the opportunity, where it will climb from six to nine hours a night within a week. I try not to change my kids’ habits too much, and one area I’m fairly disciplined with is maintaining a predictable sleep/wake cycle, even when they’re on vacation. I’ve learned, mainly through trial and error, that I suffer the consequences when my own kids don’t get enough sleep, or when their sleep cycle is thrown off. It wasn’t always like this. I remember a period of what felt like years when I had to crawl out of my child’s bedroom on my hands and knees so as to not disturb a child who simply would not fall asleep. And when it finally, mercifully, occurred, it would be a brief respite before the cycle began again. The sleepless nights left us all cranky and exhausted. Admittedly I was fortunate, either due to my successful parenting (but more likely mean reversion) and my kids are pretty good sleepers now. I’m reminded of my good fortune when I speak with exhausted and frustrated parents who have children that cannot sleep and are worried about the causes and consequences of persistent insomnia. As a pharmacist I’m regularly asked about insomnia for both kids and adults as there are a number of over-the-counter products available, and many consumers are understandably apprehensive about seeking out prescription products. Tell someone there’s “natural supplement” for sleep and there’s usually a lot of interest. That’s what I’ve seen with melatonin, a hormone that is sold without a prescription in Canada, the United States, and other countries. It is widely perceived as safe and alternative health purveyors like naturopaths, and even some health professionals, may recommend it for treating sleeping problems in both adults and children. Beyond sleeping, some believe melatonin is a wonder drug with efficacy for diseases ranging from chronic fatigue to cancer to irritable bowel. (more…)
Back in 2008, I tried to look objectively at the scientific evidence for and against circumcision. I got a lot of flak from commenters who focused on the ethical issues rather than the scientific evidence. I concluded that the evidence showed small benefits and small risks, and I didn’t advocate either for or against the procedure. At the time, the American Academy of Pediatrics’ position was:
Existing scientific evidence demonstrates potential medical benefits of newborn male circumcision; however, these data are not sufficient to recommend routine neonatal circumcision. In circumstances in which there are potential benefits and risks, yet the procedure is not essential to the child’s current well-being, parents should determine what is in the best interest of the child.
On August 27, 2012, the American Academy of Pediatrics issued a revised Circumcision Policy Statement saying that the benefits outweigh the risks.
Some of our readers have complained that we pick on alternative medicine while ignoring the problems in conventional medicine. That criticism is unjustified: we oppose non-science-based medicine wherever we find it. We find it regularly in alternative medicine; we find it less frequently in conventional medicine, but when we do, we speak out. A new book by Dr. Peter Palmieri is aimed squarely at failure to use science-based medicine in conventional practice.
Dr. Palmieri is a pediatrician who strives to provide the best compassionate, cost-effective, science-based care to all his patients. Over 15 years of practice in various settings, he observed that many of his colleagues were practicing substandard medicine. He tried to understand what led to that situation and how it might be remedied. The result is a gem of a book: Suffer the Children: Flaws, Foibles, Fallacies and the Grave Shortcomings of Pediatric Care. Its lessons are important and are not limited to pediatrics: every health care provider and every patient could benefit from reading this book.
The chapters cover these subjects:
- How doctors mishandle the most common childhood illnesses
- How doctors succumb to parental demands
- How they embrace superstition and magical beliefs
- How they fall prey to cognitive errors
- How they order the wrong test at the wrong time on the wrong patient
- How financial conflicts of interest defile the medical profession
- How doctors undermine parents’ confidence by labeling their children as ill
- A prescription for change
As much as I support vaccines, I see the short term consequences. Vaccines can be painful. Kids don’t like them, and parents don’t like seeing their children suffer. That this transient pain is the most common consequence of gaining protection from fatal illnesses seems like a fair trade-off to me. But that’s not the case for every parent.
Today’s post isn’t going to focus on the extremes of the anti-vaccination movement. Rather, it’s going to look at ways to make vaccines less painful and more acceptable to children. The pain of vaccines can lead to anxiety, fear, and even nonadherence with vaccination schedules. Fear of needles and injections is not uncommon, it’s estimated that 10% of the population avoids vaccinations for this reason.
The vaccine schedules are intense. Where I live, the public vaccination schedule specifies seventeen injections of six different products over six visits in the first 18 months of life, plus influenza vaccinations and one-offs like H1N1. That’s a lot of visits, and a lot of tears if a child doesn’t handle them well.
In light of what’s known about the prevalence of needle fears, their potential effect on vaccination adherence (that could persist through adult life), and the possible impact on public health because of unvaccinated individuals, it makes sense to do whatever we can to minimize the pain and discomfort of vaccines, increasing their acceptance to children and their parents. But what works? I’ve personally found Smarties (the real ones) and Dora the Explorer stickers are effective distractions and bribes. But I’m not about to call my n=2 trial good science. Nicely, there’s much more evidence to guide our recommendations.
