Sandra Nette is a prisoner, condemned to spend the rest of her life in the cruelest form of solitary confinement. Her intact mind is trapped in a paralyzed body and she is unable to speak. She can move one arm just enough to type on a special keyboard. She cannot swallow or breathe on her own, and must be frequently suctioned. She feels sensations and is in pain. Her condition is known as “locked-in syndrome” and has been described as “the closest thing to being buried alive.” She is suing those responsible for her cruel fate and I hope she wins.
She was a healthy 40 year old woman who wanted to stay healthy. She did all the right things like watching her weight, eating right, and not smoking. She followed the advice of a chiropractor to include regular maintenance chiropractic adjustments in her health regimen. On September 13, 2007 she had the last adjustment she would ever have.
There was nothing wrong with her. She didn’t see the chiropractor for headaches, neck pain, back pain or any other complaint. She went for a “tune-up” that she thought would help keep her healthy. The chiropractor did a rapid-thrust adjustment on her neck. Right afterwards, she complained of feeling “sore, dizzy and unwell.” She tried to leave but had to sit down. The chiropractor failed to recognize the medical emergency, and instead of calling an ambulance he recommended that she would benefit from purchasing massage therapy from his clinic. He let her leave the office and drive home alone. She only made it part way. (more…)
A long time ago I read a study about what makes a good doctor. Some things you might think were important, like grades in medical school, were irrelevant. What correlated the best was the number of medical journals a doctor read. I don’t know whether that means good doctors read more journals or reading more journals makes a better doctor.
One thing I do know is that most of us could learn better journal-reading skills. When I was a busy clinician, I did what I suspect many busy clinicians do: I let the journals pile up for a while, then tackled a stack when I got motivated. I would skim the table of contents to pick out articles that I wanted to read, then I would read the abstracts of those articles. If the abstract interested me, I would read the discussion section of the article. If I was still interested, I might go back and read the entire article. But until after I retired, I never really developed the skills to evaluate the quality of the study.
I knew enough not to jump on the bandwagon the first time something was reported, because I had seen promising treatments bite the dust with further testing. But I really wasn’t aware of all the things that can go wrong in a study, and I didn’t know what to look for to decide if the results were really credible. I’m not an academic; I thought the authors knew a lot more than I did, and I trusted them to a degree that was not warranted. (more…)
I wonder how many people have heard that chiropractic neck adjustments can cause strokes. It isn’t exactly common knowledge. One organization is trying to raise public awareness through signs on the side of city buses (Injured by a Chiropractor? Call this number) and through TV commercials. I had never heard about this phenomenon myself until a few years ago, when I heard it mentioned on an episode of Alan Alda’s Scientific American Frontiers. I questioned his accuracy, but I quickly found confirmation in the medical literature.
A typical case was that of 24 year old Kristi Bedenbaugh who saw her chiropractor for sinus headaches. During a neck manipulation she suffered a brain stem stroke and she died three days later. Autopsy revealed that the manipulation had split the inside walls of both of her vertebral arteries, causing the walls to balloon and block the blood supply to the lower part of her brain. Additional studies concluded that blood clots had formed on the days the manipulation took place. The chiropractor later paid a $1000 fine. (more…)
I recently read a fascinating book, The Brain That Changes Itself by Norman Doidge. He describes case histories and research indicating that the brain is far more malleable than we once thought. We used to think each function was localized to a small area of the brain and if you lost that area of brain tissue the function was gone forever. We once thought you couldn’t teach an old dog new tricks. Now we know better.
Learning a new skill actually changes the structure and function of the brain, even into old age. If you exercise one finger, the area of the brain devoted to that finger enlarges. The old concept of dedicated brain areas for specific functions no longer holds. Areas of the cortex that normally process vision can learn to process totally different inputs such as hearing. This is what happens with blind people: their hearing skills are enhanced when new neural connections for hearing invade the disused visual cortex. They may not actually have better hearing acuity, but they have learned to pay more attention to auditory input and to use it to build up a representation of the world around them.
One of the more intriguing experiments he describes was in monkeys. When sensory input nerves to one arm were severed, the monkey stopped using the arm, even though the motor nerves were intact. When the good arm was put in a sling, the monkey started using the impaired arm again. When both arms were deprived of sensory input, the monkey used both arms. (more…)
There is a new industry offering preventive health screening services direct to the public. A few years ago it was common to see ads for whole body CT scan screening at free-standing CT centers. That fad sort of faded away after numerous organizations pointed out that there was considerable radiation involved and the dangers outweighed any potential benefits.
Now what I most commonly see are ads for ultrasound screening. In fact, I am sick and tired of finding them in my mailbox and between the pages of my local newspaper. Ultrasound is certainly safe, with no radiation exposure. It sounds like it might be a good idea, but it isn’t.
Life Line Screening advertises itself as “America’s leading provider of quality health screenings.” They offer “4 tests in less than 1 hour – tests that can save your life.” They travel around the country, setting up their equipment in community centers, churches, and YMCAs. For $129 you get ultrasounds of your carotid arteries, your abdominal aorta, your legs, and your heel bone. They mail you your results 21 days later. (more…)
