Currently, we witness an unprecedented hype about the ALKALINE DIET. It seems to be everywhere: on TV, radio, in the dailies, magazines, books and the Internet. The diet is being promoted for an amazing array of conditions by a dazzling list of VIPs. To me this merely indicates that very important people have paid very little attention when it was explained to them how the body controls its pH. It seems that VIPs tend listen to stuff that is not only factually incorrect but potentially dangerous. (Perhaps ‘VIP’ stands for ‘very ignorant person’?) This website (one of millions on the subject) is as good an example as any for the level of misinformation that is currently out there:

When a food is ingested, digested, and absorbed, each component of that food will present itself to the kidneys as either an acid-forming compound or a base-forming one. And when the sum total of all the acid-producing and the base-producing micro and macronutrients are tabulated, we’re left with a calculated acid-base load.

One common problem with most industrialized societies is that our diets produce what’s called a “low grade chronic metabolic acidosis.” This means we’re in a chronic state of high acidity. Since the body must, at all costs, operate at a stable pH, any dietary acid load ha to be neutralized by one of a number of homeostatic base-producing mechanisms. Although the pH of the body is maintained, many cells of the body will suffer.

A cancerous cell is acidic. If your body is in a constant state of over-acidification, it becomes impossible for healthy cells to regenerate. Cancer cells thrive in an overly acidic environment. By taking action to become more alkaline, you can make it more difficult for cancer cells to regenerate.

Eating an acid/alkaline balanced diet is the key to staying healthy. Understanding the pH of the foods that you eat is relative to the state of your body’s health.

The goal of the acid alkaline balance diet, also known as the alkaline diet and the alkaline ash diet, is to achieve an optimal balance between acid-forming and alkaline-forming foods. The anti cancer diet greatly reduces the strain on the body’s acid-detoxification systems.

END OF QUOTE  (I corrected several spelling mistakes)

Personally, I don’t care a hoot whether VIPs eat this or any other diet. When it comes to claiming that the ALKALINE DIET can treat or prevent cancer (or other serious conditions) I do, however, get concerned. Such claims will almost inevitably prompt patients to give up their treatments in the hope that the diet will do the trick. In other words, such claims endanger the lives of patients, and I find this intolerable. Tragically, a recent case seems to demonstrate how real this danger is.

So, allow me to put the record straight: there is no evidence that the Alkaline Diet is effective for the prevention or treatment of any disease, particularly not cancer. For those who find this hard to believe (vis a vis the current hype, this would hardly be surprising), here is the evidence.

One systematic review concluded that despite the promotion of the alkaline diet and alkaline water by the media and salespeople, there is almost no actual research to either support or disprove these ideas. This systematic review of the literature revealed a lack of evidence for or against diet acid load and/or alkaline water for the initiation or treatment of cancer. Promotion of alkaline diet and alkaline water to the public for cancer prevention or treatment is not justified.

Another group of researchers evaluated the following diets: raw vegetables and fruits, alkaline diet, macrobiotics, Gerson’s regime, Budwig’s and low carbohydrate or ketogenic diet. They did not find clinical evidence supporting any of the diets. Furthermore, case reports and pre-clinical data point to the potential harm of some of these diets. The authors concluded that considering the lack of evidence of benefits from cancer diets and potential harm by malnutrition, oncologists should engage more in counselling cancer patients on such diets. Our recommendations could be helpful in this process.

So, yet again we are confronted with the fact that the media create attention, hype and misinformation with no real substance whatsoever. It is high time, I think, that journalists are reminded of their duty to report truthfully and responsibly!!!

Health journalists must be reminded of the undeniable fact that misinformation kills people.

The Committees of Advertising Practice (CAP) write and maintain the UK Advertising Codes, which are administered by the Advertising Standards Authority. On their website, the CAP recently published an updated advertising code for naturopathy. As we have regularly discussed the fact that the public is being frequently misled in this area, I consider the code important in the context of this blog. I therefore take the liberty of repeating it here – not least in the hope that this helps preventing misinformation in the future [the numbers in square brackets refer to me footnotes below].

What is Naturopathy?

Naturopathy is a holistic [1] approach to healthcare that uses a combination of one or more different disciplines (for example herbal medicine or hydrotherapy) and a healthy lifestyle [2] in order to gain and maintain a healthy body [3].

What claims are likely to be acceptable?

The promotion of a healthy [4] lifestyle is likely to acceptable as are claims that go no further than those commonly accepted for healthy [4] eating, sleeping well, taking exercise and the like.

What claims are likely to be problematic?

The ASA and CAP have not yet been provided with evidence which demonstrates that Naturopathy can be used to treat medical conditions (Rule 12.1).  Therefore, any claims that go beyond accepted claims for a healthy [4] lifestyle are likely to be problematic [5] unless they are supported by a robust body of evidence.  In 2013, the ASA ruled against claims on a marketer’s website which said that Naturopathy could be used to treat acute and chronic illness and disease because the marketer had not provided any evidence in support of their claims (CNM The College of Naturopathic Medicine Ltd, 13 March 2013).

What about serious medical conditions?

Claims to offer treatment on conditions for which medical supervision should be sought [6] are likely to be considered to discourage essential treatment unless that treatment is carried out under the supervision of a suitably qualified health professional (Rule 12.2).

END OF QUOTE

Naturopathy has been the subject of my posts before – see for instance here, here, here, here and here. Naturopathy can be dangerous to the point where it can kill the patient – see for instance here and here. Therefore it is important that advertising gets regulated. To make it very clear: the above statement by the CAP is, in my view, a step in the right direction, and I encourage alternative practitioners to look up the equivalent CAP documents for their specific therapy.

Having said that, I still feel the need to make a few comments:

  1. It is misleading to call naturopathy ‘holistic’. This is often factually incorrect and also gives the impression that conventional medicine is not holistic – see also here.
  2. Are we sure that all lifestyles promoted by naturopaths are, in fact, healthy?
  3. Maintaining a healthy body is naturopathy speak for DISEASE PREVENTION. Who decides what is effective prevention? On what evidence? How come many naturopaths are against the most effective means of prevention of all times – vaccination?
  4. Who decides what is ‘healthy’? On what evidence?
  5. Why ‘problematic’? Are they not wrong or bogus or false or fraudulent or criminal?
  6. Are there conditions for which medical supervision should not be sought? Which are they?

Whenever a level-headed person discloses that a specific alternative therapy is not based on good evidence, you can bet your last shirt that a proponent of the said treatment responds by claiming that conventional medicine is not much better.

There are several variations to this theme. Today I want to focus on just one of them, namely the counter-claim that, only a short while ago, conventional medicine was not much better than the said alternative therapy (the implication is that it must be unfair to demand evidence from alternative medicine, while accepting a similar state of affairs in conventional medicine). The argument has recently been formulated by one commentator on this blog as follows:

“Trepanation, leeches for UTI’s, and bloodletting are all historical treatments of medical doctors…It’s hypocritical… to impute mainstream chiropractice to the profession’s beginnings and yet not admit that medicine’s founding and evolution was inbued with consistently scientific rigor.”

Sadly, some people seem to be convinced by such words, and this is why they are being repeated ad nauseam by interested parties. Yet the argument is fallacious for a range of reasons.

  • Firstly, it is based on the classical ‘tu quoque’ fallacy (appeal to hypocrisy).
  • Secondly – unless we happen to be historians – it is not the healthcare of the past that is relevant to our discussions. The question cannot be what this or that group of clinicians used to do; the question is HOW DO THEY TREAT THEIR PATIENTS TODAY?

As soon as we focus on this issue, it is impossible to deny that conventional medicine has made lots of progress and moved light years away from treatments such as trepanation, leeches, bloodletting and many others.

Why?

Why did we make such huge progress?

Because research showed that many of the traditional treatments were ineffective, unsafe and/or implausible (thus demonstrating that hundreds of years of experience – which alternative therapists rate so very highly – is of more than dubious value), and because we consequently developed and tested new therapies and subsequently used those treatments that passed these tests and were proven to do more good than harm.

By contrast, in the last decades, centuries and millennia, homeopathy, chiropractic, acupuncture, paranormal healing etc. did make no (or very little) progress. So much so that Hahnemann, for instance, would pass any exam for  homeopathy today. (If you disagree with this statement, please post a list of those treatments that have been given up by alternative therapists in the last 100 years or so.) Come to think of it, it is a hallmark of alternative medicine that it does not progress in the way conventional medicine does. It is almost completely static, a fact, that renders it akin to a dogma or a cult.

But why? Why is there no real progress in alternative medicine?

Don’t tell me that there is no research, research funding, etc. There are now hundreds of studies of homeopathy or chiropractic, thousands of acupuncture, and dozens of paranormal healing, for instance. The trouble is not the paucity of such research but its findings! The totality of the evidence in each of these areas fails to show that the therapy in question is efficacious.

And there we have, I think, another hallmark of alternative medicine: it is an area where research is only acted upon, if its findings are in line with the preconceptions and aspirations of its proponents.

I find this interesting!

It means, amongst other things, that research into alternative medicine tends not to be used for finding the truth or establishing new knowledge; it is mainly employed for the promotion of the therapy in question, regardless of what the truth about it might be (this would disqualify this exercise from being research and qualify it as PSEUDO-RESEARCH). If the research findings are such that they cannot be used for promotion, they are simply ignored or defamed as inadequate.

This new RCT was embargoed until today; so, I had to wait until I was able to publish my comments. Here are the essentials of the study:

The Swedish investigators compared the effect of two types of acupuncture versus no acupuncture in infants with colic in public child health centres (CHCs). The study was designed as a multicentre, randomised controlled, single-blind, three-armed trial (ACU-COL) comparing two styles of acupuncture with no acupuncture, as an adjunct to standard care. Among 426 infants whose parents sought help for colic and registered their child’s fussing/crying in a diary, 157 fulfilled the criteria for colic and 147 started the intervention.

Parallel to usual care, study participants visited the study CHC twice a week for 2 weeks. Thus, all infants received usual care plus 4 extra visits to a CHC, during which parents met a nurse for 20–30 min and were able to discuss their infant’s symptoms. Together these were considered to represent gold standard care. The nurse listened, and gave evidence-based advice and calming reassurance. Breastfeeding mothers were encouraged to continue breastfeeding. At each visit, the study nurse carried the infant to a separate treatment room where they were left alone with the acupuncturist for 5 min.

The acupuncturist treated the baby according to group allocation and recorded the treatment procedures and any adverse events. Disposable stainless steel 0.20×13 mm Vinco needles (Helio, Jiangsu Province, China) were used. Infants allocated to group A received standardised MA at LI4. One needle was inserted to a depth of approximately 3 mm unilaterally for 2–5 s and then withdrawn without stimulation. Infants allocated to group B received semi-standardised individualised acupuncture, mimicking clinical TCM practice. Following a manual, the acupuncturists were able to choose one point, or any combination of Sifeng, LI4 and ST36, depending on the infant’s symptoms, as reported in the diary. A maximum of five insertions were allowed per treatment. Needling at Sifeng consisted of 4 insertions, each to a depth of approximately 1 mm for 1 s. At LI4 and ST36, needles were inserted to a depth of approximately 3 mm, uni- or bilaterally. Needles could be retained for 30 seconds. De qi was not sought, therefore stimulation was similarly minimal in groups A and B. Infants in group C spent 5 min alone with the acupuncturist without receiving acupuncture.

The effect of the two types of acupuncture was similar and both were superior to gold standard care alone. Relative to baseline, there was a greater relative reduction in time spent crying and colicky crying by the second intervention week (p=0.050) and follow-up period (p=0.031), respectively, in infants receiving either type of acupuncture. More infants receiving acupuncture cried <3 hours/day, and thereby no longer fulfilled criteria for colic, in the first (p=0.040) and second (p=0.006) intervention weeks. No serious adverse events were reported.

The authors concluded that acupuncture appears to reduce crying in infants with colic safely.

Notice that the investigators are cautious and state in the abstract that “acupuncture appears to reduce crying…” Their conclusions from the actual article are, however, quite different; here they state the following:

Among those initially experiencing excessive infant crying, the majority of parents reported normal values once the infant’s crying had been evaluated in a diary and a diet free of cow’s milk had been introduced. Therefore, objective measurement of crying and exclusion of cow’s milk protein are recommended as first steps, to avoid unnecessary treatment. For those infants that continue to cry >3 hours/day, acupuncture may be an effective treatment option. The two styles of MA tested in ACU-COL had similar effects; both reduced crying in infants with colic and had no serious side effects. However, there is a need for further research to find the optimal needling locations, stimulation and treatment intervals.

Such phraseology is much more assertive and seems to assume acupuncture caused specific therapeutic effects. Yet, I think, this assumption is not warranted.

In fact, I believe, the study shows almost the opposite of what the authors conclude. Both minimal and TCM acupuncture seemed to reduce the symptoms of colic compared to no acupuncture at all. I think, this confirms previous research showing that acupuncture is a ‘theatrical placebo’. The study was designed without an adequate placebo group. It would have been easy to use some form of sham acupuncture in the control group. Why did the authors not do that? Heaven knows, but one might speculate that they were aiming for a positive result – and what better way to ensure it than with a ‘no treatment’ control group?

There are, of course, numerous other flaws. For instance, Prof David Colquhoun FRS, Professor of Pharmacology at University College London, criticised the study because of its lousy statistics:

START OF QUOTE

“It is truly astonishing that, in the 21st century, the BMJ still publishes a journal devoted to a form of pre-scientific medicine which after more than 3000 trials has still not been able to produce convincing evidence of efficacy1. Like most forms of alternative medicine, acupuncture has been advocated for a vast range of problems, and there is little evidence that it works for any of them. Colic has not been prominent in these claims. What parent would think that sticking needles into their baby would stop it crying? The idea sounds bizarre. It is. This paper certainly doesn’t show that it works.

“The statistical analysis in the paper is incompetent. This should have been detected by the referees, but wasn’t.  For a start, the opening statement, ‘A two-sided P value ≤0.05 was considered statistically significant’ is simply unacceptable in the light of all recent work about reproducibility.  Still worse, Table 1 uses the description ‘statistical tendency towards significance (p=0.051–0.1)’.

“Worst of all, Table 1 reports 24 different P values, of which three are (just) below 0.05. Yet no correction has been used for multiple comparisons. This is very bad practice. It’s highly unlikely that, if the proper correction had been done, any of the results would have given a type 1 error rate below 5%.

“Even were it not for this, most of the ‘significant’ P values are marginal (only slightly less than 0.05).  It is now well known that the type 1 error rate gives an optimistic view. What matters is the false positive rate – the chance that a ‘significant’ result is a false positive.  A p-value close to 0.05 implies that there is at least a 30% chance that they are false positives.  If one thought, a priori, that the chance of colic being cured by sticking needles into a baby was less than 50%, the false positive rate could easily be greater than 80%2.  It is now recognised that this misinterpretation of p-values is a major contributor to the crisis of reproducibility.

“Other problems concern the power calculation.  A priori calculations of power are well-known to be overoptimistic, because small trials usually overestimate the effect size.  In this case the initial estimated sample size was not attained, and a rather mysterious recalculation of power was used.

“Another small problem: the discussion points out that ‘the majority of infants in this cohort did not have colic’.

“The nature of the control group is not very clear. An appropriate control might have been to cuddle the baby – this was used in a study in which another implausible treatment, chiropractic, was shown not to work.  This appears not to have been done.

“Lastly, p-values are reported in the text without mention of effect sizes. This is contrary to all statistical advice.

“In conclusion, the design of the trial is reasonable (apart from the control group) but the statistical analysis is appalling.  It’s very likely that there aren’t any real effects of acupuncture at all. This paper serves more to muddy the waters than to add useful information. It’s a model for the sort of mistakes that have led to the crisis in reproducibility.  The BMJ should not be publishing this sort of stuff, and the referees seem to have no understanding of statistics.”

END OF QUOTE

Despite these rather obvious – some would say fatal – flaws, the editor of ACUPUNCTURE IN MEDICINE (AIM) thought this trial to be so impressively rigorous that he issued a press-release about it. This, I think, is particularly telling, perhaps even humorous: it shows what kind of a journal AIM is, and also provides an insight into the state of acupuncture research in general.

The long and short of it is that conclusions about specific therapeutic effects of acupuncture are not permissible. We know that colicky babies respond even to minimal attention, and this trial confirms that even a little additional TLC in the form of acupuncture will generate an effect. The observed outcome is most likely unrelated to acupuncture.

Originally, I had meant this blog to discuss all types of alternative therapies – well, perhaps not all (there are simply too many of them), but at least the most popular ones. And so far, I have omitted one that seems certainly quite wide-spread: CRYSTAL HEALING.

What the Dickens is crystal healing, you ask? It is the attempt to bring about healing with the power of crystals, of course. And how is it supposed to work? This is where things get quite nebulous; this website, for instance tells us that the repeating chemical structure of crystals is said to invest them with a kind of memory. This means that crystals have the power to hold energies. You may hold a quartz crystal with the intention of filling it with your love. This is what is meant by programming a crystal. You do not need any wires or a special connection with God – all you need is intention and focus. The crystal will remember your love, which will then permeate any environment in which the crystal is placed. Crystals can remember negative as well as positive energies and so will sometimes need to be cleansed. For instance, an amethyst will actually help to cleanse a room of negative energies (eg. anger) but this means that the amethyst, which will retain an element of that negative energy, will itself occasionally require cleansing.

Most crystal healers make fairly specific claims about the healing power of specific crystals. This website explains it in some detail. The following text is an extract of several key (only marginally altered) passages from much longer instructions about the use of different crystals for healing purposes:

Crystal healing specialists generally agree that garnet promotes rapid general healing and regeneration in users. Garnet also has a positive effect on disorders such as acid reflux, blood-related illnesses, and physical strength.

Rose quartz is considered, by practitioners of alternative medicine, to be the stone of love—in this case, love of the self, in the form of self-esteem and self-worth. Rose quartz is simply brimming with happiness, and is a very positive stone that can help bring out forgiveness, compassion, and tolerance in users.

Fluorite is of mental order and clarity, and can be used to help alleviate instability, paving the way for a more balanced view of life. Feeling tossed about on a sea of restless emotions? Try carrying fluorite with you throughout the day—it helps cleanse and detoxify the centers of emotion. Fluorite is also the stone of learning, and can improve concentration and focus, while simultaneously reducing the anxiety that can sometimes make retaining information difficult. If you’re a student, learning a new instrument, or facing a complex new job, fluorite may be the stone you’ll want to keep on your person.

Lapis lazuli is beneficial to the throat, vocal cords, and larynx, and can help to regulate endocrine and thyroid issues. This is one of the most effective stones to meditate with, as lapis lazuli is the stone of higher awareness, able to bring information to the mind in images rather than words. This is an especially great boon to those who have creative jobs, as their next big inspiration can come from this.

If you suffer from anxiety, hematite is for you. A heavy, calming stone, hematite is very grounding—it leaves the user feeling comfortable and “in the moment,” rather than being lost in memory or worry. This disconnection from the present—which many of us suffer from—is the cause of much discomfort. But by practicing mindfulness through meditation with hematite, you can reconnect with what’s currently going on in your life.

Alternative medicine practitioners consider jade to be the stone of the heart, and as such, affects this organ in a positive way, promoting heart health. Not only does jade promote physical heart health, but heals emotionally, as well. Focusing energies on the emotional heart, jade helps regulate what we embrace and what we resist, giving us better self-control, as well as a better picture of our own wants and needs.

Turquoise is powerful, giving peace to the spirit and well-being to the body. This stone induces a sense of serenity, keeping physically harmful stress and inflammation at bay. Holding turquoise can bring back focus and restore vitality. Turquoise is also a stabilizer, and can calm the nerves when working on a difficult problem, or when performing or speaking in public. It is known for its effectiveness in alleviating the fear of flying.

Obsidian is a protective stone, able to remove and guard against negativity. If you are trying to release issues from your past, including emotions such as anger, resentment, and fear, handling obsidian can help by allowing you to see them for what they are so that they can be dealt with. Physically, obsidian is said to benefit good health in muscle tissue and the digestive system, and can help rid the body of infection. It helps to reduce the pain of arthritis, joint problems, and cramps.

Citrine holds the power of granting energy and stamina and supporting proper metabolism. Especially beneficial for those suffering from chronic fatigue syndrome, this stone can bring back some much-needed vitality, and can even alleviate nausea and vomiting for those suffering from morning sickness. This gem also aids in keeping the nails, skin, and hair healthy, and is effective in relieving skin irritation of any kind. Emotionally, citrine is the gem of joy, helping the subconscious mind to accept happiness in life, releasing anger and negativity. This is the most effective gem for those suffering from depression—combined with the skills of a trained counselor, meditation with citrine can help channel happiness through you, imbuing you with real joy.

Whether you believe in the healing power of crystals or not, they are worth trying alongside your normal health regimen. At best, you’ll find a spiritual support for your physical and mental health goals. And at worst? You’ll be in possession of a few beautiful stones that make great meditative focal points. So do a little research and go try out a few of your favorite stones!

END OF QUOTES

Recently, I promised to be more respectful in my criticism of quackery, but when it comes to things like crystal healing this is a difficult task indeed. It goes almost without saying that there is not a jot of evidence for any of the therapeutic claims made in the above quotes or other promotional texts on crystal healing.

Who publishes this sort of nonsense? The above excerpts come from ‘BELIEFNET‘, the “leading lifestyle site dedicated to faith and inspiration. Beliefnet helps people find and walk a spiritual path that instills comfort, hope, strength and happiness. It is through this discovery that our readers are empowered to live a more meaningful life.”

Say no more!

The ‘CHRONICLE OF CHIROPRACTIC’ recently reported on the relentless battle within the chiropractic profession about the issue of ‘subluxation’. Here is (slightly abbreviated) what this publication had to say:

START OF QUOTE

Calling subluxation based chiropractors “unacceptable creatures” chiropractic researcher Keith H Charlton DC, MPhil, MPainMed, PhD, FICC, recently stated “. . . that it is no longer scientifically acceptable for any responsible chiropractic clinician to ever use the word subluxation except as theory . . .” Charlton made the comment to members of the Chiropractic Research Alliance a group of subluxation deniers who routinely disparage the concept of subluxation.

Charlton is a well known “Subluxation Denier” and frequently attacks subluxation based chiropractors in his peer reviewed research papers and on Facebook groups. According to Charlton in a paper published in the journal Chiropractic and Osteopathy: “The dogma of subluxation is perhaps the greatest single barrier to professional development for chiropractors. It skews the practice of the art in directions that bring ridicule from the scientific community and uncertainty among the public.”

On January 5, 2017 Charlton further stated: “We need NOW in 2017 and beyond to get rid of the quacks that do us so much harm. They need to be treated personally and professionally as utterly unacceptable creatures to be shunned and opposed at every turn. Time to get going on cleaning out the trash. And that includes all signs, websites, literature, handouts and speech of staff and chiropractors.”

…Charlton has testified against subluxation based chiropractors in regulatory board actions and appears to revel in it.

In his most recent pronouncement Charlton states that he is okay with subluxation as a “regional spine shape distortion” and asserts that this is a CBP subluxation. This contention is common with subluxation deniers who are willing to accept an orthopedic definition of subluxation absent the neurological component.

…Charlton states he uses the following techniques on his website:

  • Applied Kinesiology
  • Diversified
  • Motion Palpation
  • Sacro-Occipital Technique
  • Activator
  • Logan Basic

When this self-declared scientist was confronted with his use of Applied Kinesiology and these other techniques his response was essentially that he is engaging in a “bait and switch” and that he just has those on his website to get patients who are looking for those things. Charlton lists 21 “research papers” on his curriculum vitae though they are all simply commentaries or reviews not original clinical research. The majority of these opinion pieces are attacks on subluxation and the chiropractors who focus on it.

END OF QUOTE

What does this tell us?

  • It seems to me that the ‘anti-subluxation’ movement with in the chiropractic profession is by no means winning the battle against the ‘hard-core subluxationists’.
  • Chiropractors cannot resist the temptation to use ad hominem attacks instead of factual arguments. I suppose this is because the latter are in short supply.
  • The ‘anti-subluxationists’ present themselves as the evidence-based side of the chiropractic spectrum. This impression might well be erroneous. Giving up the myth of subluxation obviously does not necessarily mean abandoning other forms of quackery.

You probably guessed: this is the headline of a new WDDTY articleWDDTY tell us that they provide “information on complimentary therapies and alternative medicines” (I don’t want to sound snobbish, but I have my doubts about people who don’t even know how to spell their subject area). As the actual article in question (on vitamin C for cancer, a subject we have discussed on this blog before here and here) is quite short, I might as well show you its full beauty:

START OF QUOTE

High-dose vitamin C does kill cancer—but only when it’s given intravenously. It’s now just a few steps away from being approved as a safe and effective cancer treatment alongside chemotherapy and radiation.

Although researchers have tested the vitamin as a cancer therapy many times, they almost always concluded that it was ineffective—but they were guaranteeing failure by giving it orally to patients.

When it’s given intravenously, it bypasses the gut and goes directly into the bloodstream—where concentrations of the vitamin are up to 500 times higher than when it’s taken orally—and targets cancer cells, say researchers at the University of Iowa.

The therapy is now going through the approval process, and could soon be available as an alternative to chemotherapy or radiation, the two conventional cancer treatments.

It’s been proved to be effective in animal studies, and phase 1 trials have demonstrated that it’s safe and well-tolerated.

Now doctors at the university are starting to use it on patients with pancreatic cancer and lung cancer, and are measuring their progress against other patients who will continue to be given chemotherapy or radiation.

Biologist Garry Buettner, who works at the university, has worked out just why vitamin C is so effective: the vitamin breaks down quickly in the body, and generates hydrogen peroxide that kills cancer cells. “Cancer cells are much less efficient in removing hydrogen peroxide than normal cells, so cancer cells are much more prone to damage and death from a high amount of hydrogen peroxide”, he explained. “This explains how very, very high levels of vitamin C do not affect normal tissue, but can be damaging to tumour tissue.”

END OF QUOTE

According to the author, these amazing claims are based on one single source: a Medline-listed article with the following abstract:

Ascorbate (AscH) functions as a versatile reducing agent. At pharmacological doses (P-AscH; [plasma AscH] ≥≈20mM), achievable through intravenous delivery, oxidation of P-AscH can produce a high flux of H2O2 in tumors. Catalase is the major enzyme for detoxifying high concentrations of H2O2. We hypothesize that sensitivity of tumor cells to P-AscH compared to normal cells is due to their lower capacity to metabolize H2O2. Rate constants for removal of H2O2 (kcell) and catalase activities were determined for 15 tumor and 10 normal cell lines of various tissue types. A differential in the capacity of cells to remove H2O2 was revealed, with the average kcell for normal cells being twice that of tumor cells. The ED50 (50% clonogenic survival) of P-AscH correlated directly with kcell and catalase activity. Catalase activity could present a promising indicator of which tumors may respond to P-AscH.

The author of the WDDTY article is Bryan Hubbard. I did not know this man but soon learnt that he is actually the co-founder of WDDTY. He may not know how to spell ‘complementary medicine’ but he certainly has a lot of fantasy! His latest drivel on vitamin C for cancer seems to prove it. He seems to have the ability to extrapolate from the truth to a point where it becomes unrecognisable. The claims he makes in his article in question certainly are in no way supported by the evidence he provided as his source.

This could be trivial; yet sadly, it isn’t: WDDTY is read by many members of the unsuspecting public. Some of them might have cancer or know someone who has cancer. These desperate patients are likely to believe what is published in WDDTY and might be tempted to act upon it. In other words, the totally misleading articles by Hubbard put lives at risk – and that I cannot find trivial!

What doctors don’t tell you is not what WDDTY suggest; doctors don’t tell you that vitamin C reverses cancer because it is not true. In view of this and other evidence, perhaps the acronym WDDTY is not the best for this publication? Could I perhaps suggest to ‘Hubbard and Co’ another abbreviation? How about MIFUC (MisInformation From Unethical Columnists)?

[yes, I know, I was tempted to chose another noun for the ‘C’, but I resisted!]

Homeopaths have, since about 200 years, insisted that their remedies are efficacious treatments for infectious diseases. As evidence for this notion, they often produce epidemiological data showing that a group of infected patients treated homeopathically had better results than another group treated conventionally. While potentially interesting, such findings never constitute proof, because the two groups might not have been comparable and many other factors could have determined the observed outcome. In fact, these stories are prime examples for the need of rigorously controlled trials when testing the efficacy of medical treatments.

Homeopaths are invariably unable to provide more compelling evidence for their claims. Instead, they repeat, since 200 years, their assumptions over and over again. Are they not aware, I ask myself, that the repetition of a lie does not create a truth?

What their repetition of lies sometimes does create, unfortunately, is some impact on a political level. This website explains it fairly well:

The Public Health Ministry (of Thailand) is thinking of implementing alternative therapy homeopathy in all districts of Sing Buri this year, after a report that it could boost the human’s body immunity to fight dengue fever, an inspector-general at the ministry said.

Homeopathic medicines had been given to Sing Buri volunteer students from kindergarten to lower-secondary level in a 2012-13 trial and it yielded satisfactory results, said Dr Jakkriss Bhumisawasdi, director of the Inspector-General Region for Bureau of Inspection and Evaluation.

The number of dengue fever cases in Sing Buri have gone down, taking its rankings from No 67 in the country (with one death) in 2011 to No 76 in 2012. As there was a nationwide dengue fever outbreak in 2013, Sing Buri reported the country’s lowest prevalence at 44.95 per 100,000 population.

Jakkriss said “homeopathy” was safe and low-cost and had been used in various countries including the United Kingdom, France, Italy, Switzerland, Belgium, the United States, Australia, India and Malaysia.

Pilot project

Next, the system of medicine would be implemented in Region 4 Bureau’s seven other provinces: Nakhon Nayok, Nonthaburi, Pathum Thani, Ayutthaya, Lop Buri, Sara Buri and Ang Thong. If this one district per province pilot project went well, they would consider implementing it across the country, he said.

Sing Buri Hospital paediatrician Dr Wali Suwatthika said the preparation involved dissolving Eupatorium herbal pills in drinking water. Each child would be given 3cc of this tasteless water every three months. The trial, which began in July 2012, covered 4,250 children in Muang district and only four of them developed mild dengue fever in one year, while seven out of the district’s 2,856 remaining kids who didn’t get the medicine had dengue fever, in a more severe condition.

Thailand reported 150,934 dengue fever patients last year, double the previous year’s number, and 133 deaths. As there is no vaccine for dengue fever, the Public Health Ministry used a combination of several measures, including the eradication of mosquito larva incubation grounds and a campaign for people to install mosquito nets.

So, where is the evidence that homeopathy does anything at all for Dengue patients? The 2012-13 trial referred to above has, as far as I can see, not been published. This probably means that it was not a publishable study at all. The only study available on Medline is this one:

A double-blind, placebo-controlled randomized trial of a homeopathic combination medication for dengue fever was carried out in municipal health clinics in Honduras. Sixty patients who met the case definition of dengue (fever plus two ancillary symptoms) were randomized to receive the homeopathic medication or placebo for 1 week, along with standard conventional analgesic treatment for dengue. The results showed no difference in outcomes between the two groups, including the number of days of fever and pain as well as analgesic use and complication rates. Only three subjects had laboratory confirmed dengue. An interesting sinusoidal curve in reported pain scores was seen in the verum group that might suggest a homeopathic aggravation or a proving. The small sample size makes conclusions difficult, but the results of this study do not suggest that this combination homeopathic remedy is effective for the symptoms that are characteristic of dengue fever.

The bottom line is simple and depressing: the totality of the best available evidence fails to show that homeopathy is efficacious for Dengue fever (or any other infectious disease). It is irresponsible to claim otherwise.

Trump says he never mocked a disabled journalist.

YET THE WHOLE WORLD SAW HIM DO IT!

UK Brexit politicians such as Boris Johnson claim they never promised £ 350 million per week of EU funds for the NHS.

BUT WE ALL SAW THE PICTURES OF THE CAMPAIGN BUS!

These are just two of the numerous, obvious and highly significant lies that we have been told in recent months. In fact, we have heard so many lies recently that some of us seem to be getting used to them. We even have a new term for the phenomenon: the ‘post-truth society’.

Personally I don’t like the word at all: it seems to reflect a tacit acceptance of lies and their legitimisation.

I find it dangerous to put up with falsehoods in that way. And I think the truth is far too valuable to abandon it without a fight. I will therefore continue to call a lie a lie!

And, by Jove, in alternative medicine, we have no shortage of them:

  • Homeopaths claiming to be able to treat any condition with their ‘high potency remedies’.
  • Chiropractors who claim that spinal manipulation improves health.
  • Healers who state that their paranormal healing affects symptoms.
  • Alternative practitioners who claim that they treat the root cause of diseases.
  • Naturopaths who pretend they can treat childhood conditions.
  • Acupuncturists who say that rebalancing yin and yang affects health.
  • Alternative practitioners who insist they can detox our bodies.
  • Politicians who claim that TCM save lives.
  • Slapping therapists who say they can cure diabetes.
  • Journalists who publish that Paleo-diet can cure inflammatory bowel diseases.
  • Entrepreneurs who promote their unproven products as diabetes cures.
  • Academics who teach homeopathy to medical students.
  • Homeopaths who claim that their remedies are effective alternatives for vaccinations.

Do I need to go on?

These are not ‘post-truths’ – these are just lies, pure and simple.

We must not be lulled into complacency or false tolerance. Lies are lies, and they are wrong and unethical. In many instances they can even kill. To ignore or accept a steady stream of lies is not a solution; on the contrary, it can easily become part of the problem.

So, let’s continue to call them by their proper name – no matter whether they originate from the dizzy heights of world politics or the low lands of quackery.

At a recent conference in Montréal (October 2016), the WFC (World Federation of Chiropractic) and the ACC (Association of Chiropractic Colleges) reached a consensus on education. Consequently, recommendations were produced that offer 12 key ‘take away messages’. I take the liberty of reproducing these statements entitled ‘Training Tomorrow’s Spine Care Experts’ (the square brackets were inserted by me and refer to brief comments I made below).

START OF QUOTE

1. Chiropractic educational institutions have a  responsibility to equip students with the skills and  attributes necessary to become future spinal health care experts. This includes a commitment to astute diagnostic ability, a comprehensive knowledge of spine-related disorders [1], appreciation for the contributions of other health professionals and a commitment to collaborative, patient-centered and evidence-informed care [2].

2. Technological advances [3] provide an opportunity for the chiropractic profession to enhance, evolve and standardize core education and practice. This is relevant to the teaching of chiropractic skills, sharing of learning resources and assessment of performance. Emerging technologies that support the development of clinically-competent practitioners should be embedded within chiropractic programs.

3. The teaching and learning of specialized manual assessment and treatment skills should remain a key distinguishing element of chiropractic curricula.

4. Surveys of the public have a demonstrated a desire for consistency in the provision of chiropractic services. Such consistency need not compromise the identities of individual institutions but will cultivate public trust and cultural authority [4].

5. Globally consistent educational and practice standards will facilitate international portability [5] and promote greater health equity in the delivery of spine care.

6. Chiropractic programs should espouse innovation and leadership in the context of ethical [6], sustainable business [7] practices.

7. Chiropractic educational curricula should reflect current evidence [8] and high quality guidelines [9], and be subjected to regular review to ensure that students are prepared to work in collaborative health care environments.

8. The training of tomorrow’ s spine care experts should incorporate current best practices in education.

9. Interdisciplinary collaboration and strategic partnerships present opportunities to position chiropractors as leaders [10] and integral team players in global spine care.

10. Chiropractic educational institutions should champion the integration of evidence informed clinical practice [11], including clinical practice guidelines, in order to optimize patient outcomes. This will in turn foster principles of lifelong learning and willingness to adapt practice methods in the light of emerging evidence [12].

11. Students, faculty, staff and administrators must all contribute to a learning environment that fosters cultural diversity, critical thinking [13], academic responsibility and scholarly activity.

12. Resources should be dedicated to embed and promote educational research activity in all chiropractic institutions.

And here are my brief comments:

[1] Some chiropractors believe that all or most human conditions are ‘spine-related disorders’. We would need a clear statement here whether the WFC/ACC do support or reject this notion and what conditions we are actually talking about.

[2] ‘Evidence-informed’??? I have come across this term before; it is used more and more by quacks of all types. It is clearly not synonymous with ‘evidence-based’, but aims at providing a veneer of respectability by creation an association with EBM. In concrete terms, asthma, for instance, might, in the eyes of some chiropractors, be an evidence-informed indication for chiropractic. In other words, ‘evidence-informed’ is merely a card blanch for promoting all sorts of nonsense.

[3] It would be good to know which technical advances they are thinking of.

[4] Public trust is best cultivated by demonstrating that chiropractic is doing more good than harm; by itself, this point sounds a bit like PR for maximising income. Sorry, I am not sure what they mean by ‘cultural authority’ – chiropractic as a cult?

[5] ‘International portability’ – nice term, but what does it mean?

[6] I get the impression that many chiropractors do not know what is meant by the term ‘ethics’.

[7] But they certainly know much about business!

[8] That is, I think, the most relevant statement in the entire text – see below.

[9] Like those by NICE which no longer recommend chiropractic for back pain? No? They are not ‘high quality’? I see, only those that recommend chiropractic fulfil this criterion!

[10] Chiropractors as leaders? Really? With their (largely ineffective) manipulations as the main contribution to the field? You have to be a chiropractor to find this realistic, I guess.

[11] Again ‘evidence-informed’ instead of ‘evidence-based’ – who are they trying to kid?

[12] The evidence that has been emerging since many years is that chiropractic manipulations fail to generate more good than harm.

[13] In the past, I got the impression that critical thinking and chiropractic are a bit like fire and water.

MY CONCLUSION FROM ALL THIS

What we have here is, in my view, little more than a mixture between politically correct drivel and wishful thinking. If chiropractors truly want chiropractic educational curricula to “reflect current evidence”, they need to teach the following main tenets:

  • Chiropractic manipulations have not been shown to be effective for any of the conditions they are currently used for.
  • Other forms of treatment are invariably preferable.
  • Subluxation, as defined by chiropractors, is a myth.
  • Spine-related disorders, as taught in many chiropractic colleges, are a myth.
  • ‘Evidence-informed’ is a term that has no meaning; the proper word is ‘evidence-based’ – and evidence-based chiropractic is a contradiction in terms.

Finally, chiropractors need to be aware of the fact that any curriculum for future clinicians must include the core elements of critical assessment and medical ethics. The two combined would automatically discontinue the worst excesses of chiropractic abuse, such as the promotion of bogus claims or the financial exploitation of the public.

But, of course, none of this is ever going to happen! Why? Because it would mean teaching students that they need to find a different profession. And this is why I feel that statements like the above are politically correct drivel which can serve only one purpose: to distract everyone from the fundamental problems in that profession.
