A significant part of my job as a pediatric hospitalist involves caring for newborns. It is arguably the best thing that I get to do as a physician, even if I do at times prefer the increased intellectual stimulation of the ill hospitalized child. While seeing newborns, I am almost always surrounded by happy and appreciative parents, grandparents and whoever else is invited to meet and greet the new arrival because the babies are almost always healthy. In fact, and not that I really care (sniff, sniff), the parents of newborns are with rare exception the only caregivers that ever thank me at discharge.
Unfortunately, sometimes I am called upon to assist babies that are having difficulty transitioning into the outside world for a variety of reasons. These reasons can range from the fairly minor and transient to the catastrophic. And despite our advances in the understanding of neonatal pathophysiology and in medical technology, there remain newborn infants that cannot be saved or who have severe lifelong deficits caused by their illness or injury. This will likely always be the case, especially if unqualified professionals continue to involve themselves in either the delivery or the care of babies.
Over the course of 11 years of practice, and after having seen thousands of both perfectly healthy and severely ill newborns, I have acquired a skill set which allows for the recognition of a baby in trouble and the ability to respond appropriately. All pediatricians and family doctors strive to develop this, particularly if they see patients in the newborn nursery, although I imagine none, including myself, would claim to have perfected this “art”. Newborn medicine can be very challenging for many reasons, not the least of which is the significant overlap of the presenting signs and symptoms of many serious conditions, with even normal baby behavior sometimes mimicking potentially life-threatening pathology.

This is another post in the naturopathy versus science series, where a naturopath’s advice is assessed against the scientific literature.
When you think medicine, your first thought may be “physician”. But the practice of medicine today is a collaboration, as few health professionals, even physicians, can deliver health care completely independently. As a pharmacist I’ve worked closely with physicians, nurses, and other health professionals my entire career. Collaboration starts early, and the setting is usually the teaching or academic hospital, which is always crawling with students, interns, and residents from all professions. Teamwork and trust are essential. In order for different professions to work effectively together, there has to be a common foundation. For medicine, that foundation is science. From basic science principles through a common understanding of fields like biochemistry and physiology, health professionals all work from the same basic understanding about how the body works and what the principles of medicine actually are. If I give a recommendation to a physician or a nurse, I’m basing that assessment on an evidence base that we both rely on. It’s not “pharmacist evidence” versus “physician evidence”, it’s “medical evidence”. This is reality-based healthcare. (more…)
It’s an excellent business model. The only real infrastructure you need is a website, and you can have a custom site made for $5-10 thousand. Then you just have the monthly bandwidth charges. The rest is just e-marketing, which can be done for free, or the cost of some e-mails lists. After that, the money just comes rolling in.
The best part is that other people do all the actual work. All you have to do is charge them for publishing on your open-access online journal.
What you are selling is essentially scientific/academic fraud.
Unfortunately, this is a good business model, even though it is a terrible scientific model, and so it has proliferated. We may be living in the heyday of dubious open-access scientific journals.
The open-access format itself is not a bad one, and there are some very successful and respected open-access journals, such as the PLOS journals. The idea is that, instead of charging a subscription in order to gain access to published articles (in print or online), the articles are open-access, but authors pay a fee to have their work published.
Old bad studies: Fantastical autopsy results
I found the following quote at “Chiropractic care can treat more than just bad backs” (FYI. Chiropractic can’t):
Luse references a study published in The Medical Times authored by Dr. Henry Windsor [sic], M.D. that showcases the correlation of spinal health to overall wellness. Windsor dissected 75 human cadavers to investigate their causes of death. The study showed that 138 of the 139 diseases of the internal organs that were present were in connection to the misalignments of the vertebrae.
But I was intrigued. So I went to the video tape. Well, the PDF.
It is an interesting read by a physician who was looking for an association between curvature of the spine and visceral pathology.
He had 50 corpses, age unknown, that he dissected, looked at the spine for curvature and then looked for pathology in organs in the same distribution of sympathetic nervous system as the level of the spine curvature.
Variations of the vitamin K molecule.
A small but increasing number of parents are refusing vitamin K injections for their newborns, an intervention recommended since 1961. This is yet another example of the difference between a science-based and philosophy-based approach to medicine. Science has given us the tool of knowledge, and in medicine that knowledge can have very practical applications.
The term “vitamin” was coined in 1912 by the Polish biochemist Kazimierz Funk. A vitamin is an organic nutrient that an organism requires in small amounts but cannot synthesize in adequate amounts and therefore must obtain from the diet. Knowledge of specific vitamins, their food source, and their biochemical activity in the body, has allowed medical scientists to cure many serious nutritional diseases, such as scurvy, rickets, and blindness.
The Vitamin K family are derivatives of 2-methyl-1,4-naphthoquinone, a fat-soluble molecule. It is a cofactor necessary for the formation of factors that function in blood clotting and in bone formation. The primary effect of vitamin K deficiency is therefore bleeding. Infants are at risk for vitamin K deficiency because this molecule does not cross the placenta well. Infants are therefore born relatively deficient in vitamin K. Further, breast milk contains little vitamin K (regardless of the mother’s diet) so infants are at risk for vitamin K deficiency until they start eating solid food at around 6 months (see Clay Jones’ post on the topic here).

There is no role of chiropractic in treating childhood bedwetting
In pediatrics, very few things are completely black and white. This is an aspect of conventional medicine in general that tends to separate the approach of science-based practitioners from that of proponents of the many forms of irregular medicine commonly discussed on SBM. They appear to experience no shame in claiming absolute certainty while doling out all manner of implausible remedies for ailments ranging from the well-established to the fictional.
While we do face questions from patients and their caregivers regarding largely invented diagnoses in pediatrics, with chronic Lyme disease and non-celiac gluten sensitivity being just two of many increasingly encountered concerns, my experience has been that alternative medical providers tend to focus their efforts on the same real problems that pediatricians and family practitioners deal with on a daily basis. And I don’t believe that it is mere coincidence that these conditions are largely self-limited in nature, a fact often not shared. Parental and patient buy-in is often more easily obtained with certainty rather than nuance.
Chiropractors, for example, seem to pride themselves on their ability to cure ear infections. Of course in greater than 80% of children with acute ear infections, symptoms will resolve without any intervention whatsoever. This is why the AAP has been trying for years to decrease the rates of antibiotic prescriptions for ear infections, unfortunately with little in the way of success thus far. And when the infections don’t resolve on their own, there is no good evidence that anything a chiropractor has to offer can help. The same can be said for their claims regarding colic and gastroesophageal reflux, which I’ve written about before.
Another condition frequently mentioned by chiropractors as being particularly in their wheelhouse is nighttime bedwetting, the medical term for this being nocturnal enuresis. Rarely have I seen a chiropractic website with a section on the benefits for children that does not mention their success in curing bedwetting. Fred Clary, DC, even claims on his website to be able to cure bedwetting in the newborn baby. And to think I’ve just been ignoring the problem as a newborn hospitalist. Is it because the thought of a newborn infant gaining continence is absurd, or am I just a shill for Big Pampers?
This is another post in the naturopathy versus science series, where a naturopath’s medical advice is assessed against the scientific evidence. Today’s topic is brought to you by Toronto naturopath Shawna Darou, who recently published her evaluation of prenatal vitamins.
Vitamin supplementation is unnecessary for the vast majority of people. You wouldn’t know this walking through a drug store, where you’ll usually find an entire aisle packed with supplements. Alternative health providers like naturopaths tend to be strong supporters of supplementation, but this advice seems to be based mainly on the belief that “vitamins are magic” rather than good science. The best research hasn’t established a strong evidence base for taking supplements. We definitely need vitamins in our diet to live. But that’s where we should be getting those vitamins – from our food, instead of from pills. If you eat a reasonable and balanced diet, and have no medical conditions that require special consideration, vitamin supplementation won’t offer meaningful health benefits. In the absence of any deficiency, vitamin supplements seem to be useless at best and harmful at worst. (more…)
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’m a dog person. I always wanted a dog as a child, and while my extended family all had dogs, we never had one in our home. I finally got my wish just over a decade ago. My wife and I were referred to a breeder with an excellent reputation for raising healthy, family-friendly Labrador Retrievers. Within moments of meeting a tiny black lab, we immediately put a deposit down. When we took Casey home a few months later she was healthy – a ball of kinetic energy. The breeder offered us a health guarantee – free of hip and elbow dysplasia, supported by certifications from the dog’s parents and grandparents. The breeder recommended we use a specific brand of food (which we ignored), and other than vaccinating her and promising not to breed her, there were few conditions for the guarantee. We were excited “parents” and that first year was a lot of fun.
At about 12 months of age, Casey started limping. At first we thought it was a temporary consequence of boisterous play. It was initially subtle, but then became very obvious – she started walking differently, and it didn’t go away. The x-rays confirmed what we feared: elbow dysplasia. Our breeder was deeply apologetic – consistent with the guarantee, she offered to replace our dog. Giving up our pet was out of the question, so we started looking at treatment options. The veterinarian offered surgery, but even he wasn’t enthusiastic, citing the very real likelihood it would do nothing. Knowing the toxicity of anti-inflammatory drugs, I wasn’t optimistic that would be tolerable for the long run. Instead we went the supplement route. (more…)
Summertime and the living is easy. I am in Sunriver, Oregon for the week and I though, hilariously, that I would have plenty of time to write a post. Between the hiking, the biking, the golf, the food and the beer, there has been little time to sit in from of a keyboard. There may be no better place to spend a week if you like the outdoors, but they do not have internet on the hike around Paulia Lake. So while a caramel banana cake bakes for a dinner tonight, I have an hour or so churn out a post. Do not expect much.
One person’s ethics is another’s belly laugh, but in medicine ethics are formalized. The basic principles in the US are
- Respect for autonomy – the patient has the right to refuse or choose their treatment (Voluntas aegroti suprema lex)
- Beneficence – a practitioner should act in the best interest of the patient (salus aegroti suprema lex)
- Non-maleficence – “first, do no harm” (primum non nocere)
- Justice – concerns the distribution of scarce health resources, and the decision of who gets what treatment (fairness and equality).
These are guidelines, not mandated, but if you get an ethics consult in my institutions the above concepts are the framework within which the consult will be completed.
Patients can only be autonomous if they are given accurate, truthful information with which to make a decision about their treatments. You can’t lie to patients, but we all know how you phrase an idea can subtly alter the response. Do you say an 80% success rate or a 20% failure rate? I tend to say both. And not everyone can handle the unvarnished, blunt truth. Part of the art of medicine is trying to tell each patient the truth, the whole truth and nothing but the truth in a manner palatable for the individual patient. It is not easy and I am certain I do not always do a good job. (more…)
