“I swear I had nothing to do with this!”
A short post today, for me at least, but an important one to file away for the next time somebody asks “What’s the harm?” during a discussion on the use of irregular medicine in the care of pediatric (or any) patients.
The September 2015 issue of Pediatrics in Review, the official American Academy of Pediatrics source for continuing medical education, contains a case report that should be of particular interest to readers of Science-Based Medicine. The authors, pediatricians at Children’s Hospital at Albany Medical Center, describe the ordeal of a six-year-old boy, previously healthy except for eczema, suffering with lower extremity pain to the point of crying with attempts to walk or to even bear weight. For those of you who don’t have experience with children of this age, it takes a considerable amount of discomfort or disability to interfere with their determination to remain in a near constant state of motion. Refusal to bear weight is a red flag that we take very seriously as the cause in a young child is often serious, ranging from traumatic injuries and severe infections of the bones or joints to diagnostic dilemmas such as leukemia and juvenile rheumatoid arthritis.

Once again, it’s influenza season. The vaccine clinics are open, and the hysterical posts about the vaccine’s danger are appearing in social media. There’s familiarity to all of this, but also a big new change – at least in Canada, where I am. Pharmacists can now administer the vaccine. And it’s completely free to anyone in Ontario (where I am), so the barriers to obtaining the vaccine are pretty much eliminated. There’s no longer a need to drag your kids to their family doctor or line up at a public health clinic. Anyone can walk into a pharmacy, show their health card, and walk out minutes later, vaccinated. It’s another enabling change that may help improve immunization rates, as uptake rates in the population remain modest.
This year’s flu season is (as of week 47) fairly quiet. Google Flu trends suggests a fairly typical picture, nothing like what we saw in 2009/10, the year of H1N1. My city’s influenza tracker reports only a dozen cases so far this season. Many of us will get our flu shot, continue with our lives, and not think about the flu until next season’s announcements. That’s the hope, anyway. Influenza can kill, and in its more virulent forms, is devastatingly deadly. The worst case scenario (so far) is almost unimaginable today. In 1918/19 an influenza pandemic killed 50 million people worldwide (5% of the population). So among public health professionals, that worry about the next wave is always present. Much has been written at this blog <plug>nicely compiled in the SBM ebook,</plug> on the efficacy and safety of the flu vaccine. In short, the vaccine is effective for both individual and population-level protection, but only modestly so, and its effectiveness varies based on its match with circulating strains. And despite widespread use for decades, there are frustrating limitations with the current vaccine beyond efficacy, including the need to repeat the shot annually. Someone said something about “going to battle with the army you have”. (I thought it was Crislip but he was quoting Rumsfeld.) The quote is apt. It’s not a perfect vaccine, but it does offer protection – if not directly to you, then indirectly to those at greater risk of infection. Hospitals and health facilities have been criticized for demanding health professionals either get the vaccine or wear a mask – and the arguments against vaccination are losing. But even the strongest advocates of influenza vaccine will acknowledge its limitations, which perhaps contributes to the understandable perception that there is more that could be done- beyond reasonable and effective precautions like handwashing and hygiene.
