Medical Science

Everything is moving so fast. The media reports on new research, studies and discoveries daily. People are living longer, healthier lives due in part to medical advancements.

 

I expect that this endless parade of seemingly miracle cures drives people to look beyond medical science and put their faith in so many unproven remedies. Scientific-sounding sales pitches, ancient wisdom or endorsements by friends, relatives and celebrities lure them in. Then all it takes is a little placebo effect to convince them that they have made a great discovery, and they too spread the word. 

 

Americans throw away countless millions of dollars in pursuit of relief from their latest aches and pains. Here are a couple more examples from reliable sources.

 

The first is about acupuncture. Many people believe acupuncture is an effective and safe alternative to mainstream medicine. Safety is not really the issue here. In the category of complimentary and alternative medicine, most of the pills and procedures are safe because they don’t do anything. The question in this case is whether it works.

 

If acupuncture works, it seems reasonable to assume that acupuncture points really exist and that experts or experienced practitioners can find them. Otherwise it would be random needling, a technique that would fly in the face of a theory based on the existence of qi and its meridians accessible at particular acupuncture points.

 

Journal of Acupuncture and Meridian Studies after looking at 14 separate studies found “’considerable variation’ in localization of acupoints among qualified medical acupuncturists.” They admit that accurate point location is a significant factor in effective treatment, but the various methods of finding them yield highly inconsistent results. 

Furthermore, my original source points out that the depth of the needles to access the point is not specified; and if the points were real, “wouldn’t they vary in location [from person to person] just as other anatomical structures” like blood vessels do? So many unanswered questions throw considerable doubt on the practice.

 

The second example concerns chiropractors charging thousand of dollars, not covered by insurance, for spinal decompression on a special device to alleviate back pain. One such device is “a mechanical table attached to Space Age-looking controls that its manufacturer claims can stretch the disks of the vertebrae.” (Medieval torture chambers had a similar table but without the space age-looking controls.) 

 

A group called Fair Warning, “based on review of lawsuits, scientific studies, government documents, chiropractic websites and interviews with experts, found that the claims of success for spinal decompression stretch the truth,” and that the treatment “has never been proven [to be effective] in scientifically rigorous studies.”

 

While Internet advertising and participating chiropractors rave about success, insurance companies describe the machines as experimental and investigative. While the promoters boast of success rates of 86% to 90%, investigators found their studies “lacked scientific rigor” and that “no definite conclusions could be drawn.”

 

A professor from Oregon Health and Science University and an expert on the subject of lower back pain says, “Eight in 10 people with back pain get better on their own.” The marginal difference with this machine, even if true, hardly seems like a good investment, especially since it has also resulted in serious injury.

 

Both cases are scientifically very dubious. Unfortunately, science means nothing to Americans unless it supports their preconceived notions. Climate change is real, based on science; but nuclear power is dangerous, based on emotion.

Is Chiropractic Effective Against COVID-19?

Everyone wants to take advantage of the pandemic; some offer products and services that lean toward quackery and others less so, but they are trying to lure in customers by playing on fear. Sometimes the connection is dubious. For example, CNN reports that the World Health Organization (WHO) “called on tobacco and nicotine industries across the world to stop taking advantage of the global pandemic and marketing directly to children and teens.” (How anyone can use the pandemic to put a positive spin on teen smoking is very puzzling, but WHO is worried.)

As another example, many chiropractors are posting information on their websites similar in wording to this one: “Regular chiropractic adjustments have been proven to boost your immune system. This is accomplished by improving the state of the nervous system which in turn improves the immune system.”

The International Chiropractic Association (ICA) found these claims troubling. Concerned with the credibility of their practice, they tried to clarify in March with a 15-page bulletin stating in part: “There are no vaccines, no drugs, no natural remedies, no alternative therapies that have been tested and the outcomes peer reviewed to meet any credible evidence-based standard in science. This includes chiropractic.” They had “previously provided clear reminders to its members of the importance of not advertising” such abilities.

Where would hundreds of chiropractors get this idea? They believe that straightening a patient’s spine positively affects the nervous system by reducing stress. Stress reduction is loosely linked to immunity. As explain in the Annals of Vertebral Subluxation, which tracks chiropractic research, “It is well established that the nervous system controls and coordinates all functions and systems of the human body including immunity and the immune system.” This theoretical connection feeds an assumption that it is ethical to advertise chiropractic as a treatment and prevention during the pandemic. But it’s not.

This train of thought – less stress to nervous system to immunity – has never been proven to exist. This site quotes another ICA report warning, “there exists no credible, scientific evidence that would permit claims of effectiveness for conferring or enhancing immunity through spinal adjustment/manipulation to be made in communications by chiropractors.” Furthermore, last month “more than 150 chiropractic researchers from eleven countries criticized [any suggestion] that chiropractic care (primarily spinal manipulation), can have a meaningful impact on immune function.”

At the end of the 15-page ICA report, they make the lack of evidence clear by asking for more funding to support “necessary clinical research required to validate the role of doctors of chiropractic in promoting health and vitality by stimulating a healthy immune response.”

As these renegade chiropractors advertise viral immunity, along with several other questionable benefits, they undermine the credibility of the profession, providing more ammunition to the naysayers. Numerous skeptical publications, including this one, describe chiropractic as teetering precariously on the edge between science and pseudoscience.

Such advertising trying to get away with unsubstantiated claims, reinforces the need for critical thinking. Many chiropractors, naturopaths and others claim all sorts of peripheral health benefits. Patients walk in expecting miracles and walk out with placebo-effect satisfaction telling their friends. But wild claims and customer endorsements don’t constitute evidence. Eventually, the professional associate must move to protect the reputation of the profession before the FTA steps in to protect consumers. But none of this would be necessary, if critical thinking prevailed.

Opposing Views on Alternative Medicine

The Association to Protect the Sick of Pseudoscientific Therapies (APETP in Spanish) was formed by victims of those therapies along with scientists, doctors, nurses, physiotherapists, computer scientists, lawyers, and many other credentialed health professionals to fight against the rise of unproven alternative medical practices in Europe. They recently published a manifesto to “raise awareness in the media about the problem of pseudo-therapies and the position of the scientific community against them.”

They feel strongly about the dangers and deception of these practices. “More than 150 pseudo-therapies have been identified as being in use throughout Europe. Thousands of citizens’ lives depend on this being prevented. In fact, according to a recent research, 25.9 % of Europeans have used pseudo-therapies last year. In other words, 192 million patients have been deceived.”

They do not list all 150 in the manifesto, but summarize a few. “Homeopathy is the best known pseudo-therapy, but it is not the only one nor the most dangerous one. Others, such as acupuncture, reiki, German New Medicine, iridology, biomagnetism, orthomolecular therapy and many more are gaining ground.” They claim that these are not only unproven, but they distract patients from seeking professional help when desperately needed. They are calling for legislation in countries around the world to combat their spread. 

In the US, practitioners of these therapies are not allowed to advertise or otherwise imply that their products can “diagnose, treat, cure or prevent any disease or any other medical condition,” but the government has not considered consumer protection legislation. In fact, the FDA and other agencies are easier on these products and practices than they are on prescription medicine in terms of testing requirements for safety and efficacy.

Meanwhile, from halfway around the world comes another example of what that group is fighting against. 

In response to the Coronavirus outbreak and WHO’s warnings, a branch of the Indian government, the Ministry of AYUSH, issued an advisory based on traditional medicine.

The first part of the release gives the typical good advice on how to behave in this environment: maintain personal hygiene; wash hands frequently; drink enough water; avoid touching your eyes, nose, and mouth; avoid close contact with sick people; stay home when sick; cover your face if you cough or sneeze; and use a mask in public places.

But next they recommend “ways and means of prevention of Coronavirus infection through Homoeopathy” and use of a variety of Unani medicines for “symptomatic management of Coronavirus infection.” (This would be illegal in the US but it is government-sponsored in India.)

Unani medicine, not common in the West, is “a form of alternative medicine, which is based on the belief that the human body contains four humors, and that imbalance of these four humors is the cause of disease,…created by the ancient Greek physician Hippocrates, which later spread to the Islamic empires...during the Middle Ages. While this belief has no scientific basis, contemporary adherents still try to propagate these beliefs as science.” [Source: Wikipedia]

 An editorial in the Times of India decried the government advisory: “When all the authorities including World Health Organization claim there is neither any vaccine nor any treatment for coronavirus, the government is promoting unproven therapies to lull people into a false sense of security that they can be safe if they consume such concoctions.” Dr. Misba Hul Bashier added on Twitter that “loads of patients developed acute liver and kidney failure due to alternative medicines.”

Of course, recommendation of useless or even dangerous steps driven by fear of the virus is not limited to the Indian government. A Canadian news story cites “quack remedies and vaccine conspiracies – a global deluge of misinformation” including a recommendation on Facebook to drink a household disinfectant and another source claiming that a saline solution, salty water, can cure it.

What can we do when misinformation abounds – petition the government for new regulations like the Europeans? Critical thinking would be a lot easier and less intrusive by trusting real evidence rather than endorsements and recommendations.

Flashback – Electro-pseudoscience

[In recent news from England “a poster for the charity Electrosensitivity-UK asked, “How safe is 5G?” They oppose the roll out of 5G technology and warned, without any scientific evidence, that it causes a “range of health effects such as ‘reduced male fertility, depression, disturbed sleep and headaches, as well as cancer’”.

This fear mongering is reminiscent of my posting in December 2014 titled “Fear of Power Lines.” This kind of panic based on bad science will keep coming up as long as a gullible public will buy into it.]

If you are old enough, you remember the big scare in the late 1980s about power lines causing cancer. In fact, if you are not old enough to remember the news reports at the time, you have probably heard about this idea from someone who was. There was a great deal of concern, but after over 30 years of further research, it appears to have been a mistaken assumption.  Still the fear persists.

This fairly short (7:46) NY Times Retro Report is worth watching.

It begins with replays of news reports from all the major networks from 1987.  It was big news at the time, and this reminder is very informative showing in retrospect how the news business operates when breaking news has the potential to stir up a lot of fear based on a very limited study.  A voice-over talks about how power lines may cause cancer while showing the picture of a small bald child, apparently battling cancer (but not from power lines) – sneaky.  When seven children in one Denver school developed cancer and parents blamed it on nearby power lines, one reporter said that it could be a “tragedy of enormous proportions.”

The Times calls the episode “Power of Fear” with the message that once this type of fear is introduced into our society it never really goes away.  

The researcher who first suspected the problem now explains that further research has ruled out any problem. With the number and density of power lines, this should have developed into a major health problem, but it didn’t. “That suspicion [of a cancer risk] was simply wrong...The likely impact [of power lines] is zero.”  

Scientists in the 1990s conducted hundreds of experiments exposing rats, other animals and human cells to intense EMFs (magnetic fields around the power lines) over long periods of time with no change in the cells.  “In 20 years of looking, no one has found a way that power line fields can do anything at all to cells of animals; unless it can do something to cells, it cannot cause cancer.” The National Academy of Sciences confirmed this by reviewing 500 studies and releasing their findings in October 1996. Nothing since then has altered the conclusion of no danger.

The association was always “suggestive, but very faint” but correlation does not prove causation. Yet the idea, the fear, persists and is still spread by some public figures, some advertisers who use the scare tactics to sell real estate service and by word of mouth – now enhanced by the reach and power of social media.

Why do some Americans believe these sources and continue to fear the presence of power lines? Psychologists tell us that risks that are invisible, that might cause suffering before death or that might affect children have uncanny staying power, even in the face of firm evidence to the contrary. This highlights the need for critical thinking, to put aside emotional responses and listen to the facts. Don’t we have enough stuff to be afraid of without dredging up errors from the past?
