It’s hard to know what to make of  David Tredinnick MP (Cons, Bosworth). He is certainly an extreme example of the scientific ignorance of our parliamentary representatives, but he isn’t alone in that. Our present minister of Education, Michael Gove, memorably referred to Newton’s Laws of Thermodynamics, blissfully unaware that thermodynamics was a 19th century development. And our present Minister of Health seems to think that magic water cures diseases.

But Mr Treddinick breaks every record for anti-scientific nonsense. That, no doubt, is why he was upset by the recent revision of come NHS Choices web pages, so that they now give a good account of the evidence (that’s their job, of course). They did that despite two years of obstruction by the Department of Health. which seemed to think that it was appropriate to take advice from Michael Dixon of the Prince’s Foundation for integrated Health. That shocking example of policy based evidence was revealed on this blog, and caused something of a stir.

Treddinick’s latest letter

A copy of a letter from Mr Tredinnick to the Minister of Health, Jeremy Hunt, has some into my possession by a tortuous route [download the letter]. It’s a corker. Here are a few quotations.

"1. UKIP moving onto our ground
Attached is an extract from a recent UKIP policy statement. The position which UKIP has taken is one with which most of our Daily Mail reading supporters of complementary medicine would agree."

It seems that Treddinick’s preferred authority on medicine is now Nigel Farage, leader of the UK’s far right party. UKIP’s policy on health is appended to the letter, and it’s as barmy as most of the other things they say.

"2. Herbal Medicine
. . .there is very real concern that the Government will not regulate Herbal Medicine and Traditional Chinese Medicine. The current situation is unacceptable, because herbal practitioners need regulation and cannot function as herbal therapists, nor can they cannot obtain stocks of their herbal remedies, without it.

This refers to a saga that has been running for at least 10 years. Herbalists are desperate to get a government stamp of approval by getting statutory regulation, much like real doctors have, despite the fact that they make money by selling sick people "an unknown dose of an ill-defined drug, of unknown effectiveness and unknown safety" (as quoted recently in the House of Lords).

Even  the US National Center for Complementary and Alternative Medicine (NCCAM) doesn’t claim that a single herbal treatment is useful. The saga of herbal regulation is long and tedious. The short version is that a very bad report, The Pittilo report, recommended regulation of herbalists. After years of prevarication, Andrew Lansley ignored the impartial scientific advice and yielded to the pressure from the herbal industry to accept the Pittilo report. But still nothing has happened.

Could it be that even Jeremy Hunt realises, deep down, that the regulation of nonsense is a nonsense that would harm the public?

We can only hope that a letter from Mr Tredinnick is the kiss of death. Perhaps his continuous pestering will only reinforce the doubts that seem to exist at the Department of Health.

Then Tredinnick returns (yawn) to his obsession with magic water. He vents his rage at the now excellent NHS Choices page on homeopathy.

3. Homeopathy

"Recently this wording has been removed and instead a comment by the Chief Medical Officer that homeopathy is placebo inserted in its place, as well as links to external organisations which campaign against homeopathy. For instance, there is a link to the Sense About Science website, and Caroline Finucane, who is Editor of new content at NHS Choices, also writes for the Sense About Science website. This is an organisation which has no expertise in homeopathy and traces its roots back to the ultra-left Revolutionary Communist Party (RCP)."

"I respectfully suggest that the original wording be reinstated and these links to external organisations be removed or changed to ensure a balanced view.".

So it seems that he prefers the medical views of Nigel Farage and the Prince of Wales to those of the Chief Medical Officer and the government’s chief scientist. Disgracefully, Tredinnick picks out one particular employee of NHS Choices among many, and one who does an excellent job. And he raises the hoary old myth that Sense About Science is a communist organisation. Odd, since others accuse it of being neo-libertarian. The actual history is here. The organisation that is a bit too libertarian for my taste is Spiked Online. I haven’t agreed with every word that Sense about Science has printed, but they have a totally honest belief in evidence.

To drag in the name of one person out of many, and to justify it by a false history shows, once again, how very venomous and vindictive the advocates of delusional medicine can be when they feel cornered.

This is what the BBC News profile says about him.

 David Tredinnick is an old style Conservative MP, being an Eton-educated former Guards officer, who has sat in the Commons since 1987. However, his ambition for high office was thwarted by his role in one of the sleaze stories which helped to sink the Major government. He accepted £1,000 from an undercover reporter to ask parliamentary questions about a fictitious drug. He was obliged to resign from his role as a PPS and was suspended from the Commons for 20 sitting days. He has not sat on the frontbench since. He is an orthodox Conservative loyalist, though he is more supportive of the European Union than many of his colleagues. He has, however, carved himself a niche as the Commons’ most enthusiastic supporter of complementary medicine. He has wearied successive health secretaries with his persistent advocacy of any and all homeopathic remedies. He has also supported their use in prisons and even suggested them as an aid in alleviating the foot and mouth crisis.

 Tredinnick has also asserted that he was aware of a psychiatric hospital that doubled its staff at full moon (this is an old urban myth, and is, of course, quite untrue). His advocacy of homeopathic borax as a way to control the 2001 epidemic of foot and mouth diease can be read here. Luckily it was ignored by the government. I hope his latest letter will be treated similarly. Picture of David Tredinnick MP from the Conservative Party

### Follow-up

Almost all the revelations about what’s taught on university courses in alternative medicine have come from post-1992 universities. (For readers not in the UK, post-1992 universities are the many new univerities created in 1992, from former polytechnics etc, and Russell group universities are the "top 20" research-intensive universities)

It is true that all the undergraduate courses are in post-1992 universities, but the advance of quackademia is by no means limited to them. The teaching at St Bartholomew’s Hospital Medical School, one of the oldest, was pretty disgraceful for example, though after protests from their own students, and from me, it is now better, I believe.

Quackery creeps into all universities to varying extents. The good ones (like Southampton) don’t run "BSc" degrees, but it still infiltrates through two main sources,

The first is via their HR departments, which are run by people who tend to be (I quote) "credulous and moronic" when it comes to science.

The other main source is in teaching to medical students. The General Medical Council says that medical students must know something about alterantive medicine and that’s quite right, A lot of their patients will use it. The problem is that the guidance is shockingly vague .

“They must be aware that many patients are interested in and choose to use a range of alternative and complementary therapies. Graduates must be aware of the existence and range of such therapies, why some patients use them, and how these might affect other types of treatment that patients are receiving.” (from Tomorrow’s Doctors, GMC)

In many medical schools, the information that medical students get is quite accurate. At UCL and at King’s (London) I have done some of the familiarisation myself. In other good medical schools, the students get some shocking stuff. St Bartholomew’s Hospital medical School was one example. Edinburgh University was another.
But there is one Russell group university where alternative myths are propagated more than any other that I know about. That is the University of Southampton.

In general, Southampton is a good place, I worked there for three years myself (1972 – 1975). The very first noise spectra I measured were calculated on a PDP computer in their excellent Institute of Sound and Vibration Research, before I wrote my own programs to do it.

But Southanpton also has a The Complementary and Integrated Medicine Research Unit . Oddly the unit’s web site, http://www.cam-research-group.co.uk, is not a university address, and a search of the university’s web site for “Complementary and Integrated Medicine Research Unit” produces no result. Nevertheless the unit is “within the School of Medicine at the University of Southampton”

Notice the usual euphemisms ‘complementary’ and ‘integrated’ in the title: the word ‘alternative’ is never used. This sort of word play is part of the bait and switch approach of alternative medicine.

The unit is quite big: ten research staff, four PhD students and two support staff It is headed by George Lewith.

### Teaching about alternative medicine to Southampton medical students.

The whole medical class seems to get quite a lot compared with other places I know about. That’s 250 students (210 on the 5-year course plus another 40 from the 4-year graduate-entry route).

Year 1:  Lecture by David Owen on ‘holism’ within the Foundation Course given to all 210 medical students doing the standard (5-year) course.

Year 2: Lecture by Lewith (on complementary medicine, focusing on acupuncture for pain) given within the nervous systems course to the whole medical student year-group (210 students).

Year 3 SBOM (scientific basis of medicine) symposium: The 3-hour session (“Complementary or Alternative Medicine: You Decide”). I’m told that attendance at this symposium is often pretty low, but many do turn up and all of them are officially ‘expected’ to attend.

There is also an optional CAM special study module chosen by 20 students in year 3, but also a small number of medical students (perhaps 2 – 3 each year?) choose to do a BMedSci research project supervised by the CAM research group and involving 16-18 weeks of study from October to May in Year 4. The CAM research group also supervise postgraduate students doing PhD research.

As always, a list of lectures doesn’t tell you much. What we need to know is what’s taught to the students and something about the people who teach it. The other interesting question is how it comes about that alternative medicine has been allowed to become so prominent in a Russell group university. It must have support from on high. In this case it isn’t hard to find out where it comes from. Here are some details.

Year 1 Dr David Owen

David Owen is not part of Lewith’s group, but a member of the Division of Medical Education headed by Dr Faith Hill (of whom, more below). He’s one of the many part-time academics in this area, being also a founder of The Natural Practice .

Owen is an advocate of homeopathy (a past president of the Faculty of Homeopathy). Homeopathy is, of course, the most barmy and discredited of all the popular sorts of alternative medicine. Among those who have discredited it is the head of the alt med unit, George Lewith himself (though oddly he still prescribes it).

And he’s also a member of the British Society of Environmental Medicine (BSEM). That sounds like a very respectable title, but don’t be deceived. It is an organisation that promotes all sorts of seriously fringe ideas. All you have to do is notice that the star speaker at their 2011 conference was none other than used-to-be a doctor, Andrew Wakefield, a man who has been responsible for the death of children from measles by causing an unfounded scare about vaccination on the basis of data that turned out to have been falsified. There is still a letter of support for Wakefield on the BSEM web site.

The BSEM specialises in exaggerated claims about ‘environmental toxins’ and uses phony allergy tests like kinesiology and the Vega test that misdiagnose allergies, but provide en excuse to prescribe expensive but unproven nutritional supplements, or expensive psychobabble like "neuro-linguistic programming".

Other registered "ecological physicians" include the infamous Dr Sarah Myhill, who, in 2010, was the subject of a damning verdict by the GMC, and Southampton’s George Lewith.

If it is wrong to expose medical students to someone who believes that dose-response curves have a negative slope (the smaller the dose the bigger the effect -I know, it’s crazy), then it is downright wicked to expose students to a supporter of Andrew Wakefield.

David Owen’s appearance on Radio Oxford, with the indomitable Andy Lewis appears on his Quackometer blog.

Year 2 Dr George Lewith

Lewith is a mystery wrapped in an enigma. He’s participated in some research that is quite good by the (generally pathetic) standards of the world of alternative medicine.

In 2001 he showed that the Vega test did not work as a method of allergy diagnosis. "Conclusion Electrodermal testing cannot be used to diagnose environmental allergies", published in the BMJ .[download reprint].

In 2003 he published "A randomized, double-blind, placebo-controlled proving trial of Belladonna 30C” [download reprint] that showed homeopathic pills with no active ingredients had no effects: The conclusion was "”Ultramolecular homeopathy has no observable clinical effects" (the word ultramolecular, in this context, means that the belladonna pills contained no belladonna).

In 2010 he again concluded that homeopathic pills were no more than placebos, as described in Despite the spin, Lewith’s paper surely signals the end of homeopathy (again). [download reprint]

What i cannot understand is that, despite his own findings, his private practice continues to prescribe the Vega machine and continues to prescribe homeopathic pills. And he continues to preach this subject to unfortunate medical students.

Lewith is also one of the practitioners recommended by BSEM. He’s a director of the "College of Medicine". And he’s also an advisor to a charity called Yes To Life. (see A thoroughly dangerous charity: YesToLife promotes nonsense cancer treatments).

3rd year Student Selected Unit

The teaching team includes:

• David Owen – Principal Clinical Teaching Fellow SoM, Holistic Physician
• George Lewith – Professor of Health Research and Consultant Physician
• Caroline Eyles – Homeopathic Physician
• Elaine Cooke – Chiropractic Practitioner
• Phine Dahle – Psychotherapist
• Keith Carr – Reiki Master
• Christine Rose – Homeopath and GP
• David Nicolson – Nutritionalist
• Shelley Baker – Aromatherapist
• Cheryl Dunford – Hypnotherapist
• Dedj Leibbrandt – Herbalist

More details of the teaching team here. There is not a single sceptic among them, so the students don’t get a debate, just propaganda.

In this case. there’s no need for the Freedom of Information Act. The handouts. and the powerpoints are on their web site. They seem to be proud of them

Let’s look at some examples

Chiropractic makes an interesting case, because, in the wake of the Singh-BCA libel case, the claims of chiropractors have been scrutinised as never before and most of their claims have turned out to be bogus. There is a close relationship between Lewith’s unit and the Anglo-European Chiropractic College (the 3rd year module includes a visit there). In fact the handout provided for students, Evidence for Chiropractic Care , was written by the College. It’s interesting because it provides no real evidence whatsoever for the effectiveness of chiropractic care. It’s fairly honest in stating that the view at present is that, for low back pain, it isn’t possible to detect any difference between the usefulness of manipulation by a physiotherapist, by an osteopath or by a chiropractor. Of course it does not draw the obvious conclusion that this makes chiropractic and osteopathy entirely redundant -you can get the same result without all the absurd mumbo jumbo that chiropractors and osteopaths love, or their high-pressure salesmanship and superfluous X-rays. Neither does it mention the sad, but entirely possible, outcome that none of the manipulations are effective for low back pain. There is, for example, no mention of the fascinating paper by Artus et al [download reprint]. This paper concludes

"symptoms seem to improve in a similar pattern in clinical trials following a wide
variety of active as well as inactive treatments."

This paper was brought to my attention through the blog run by the exellent physiotherapist, Neil O’Connell. He comments

“If this finding is supported by future studies it might suggest that we can’t even claim victory through the non-specific effects of our interventions such as care, attention and placebo. People enrolled in trials for back pain may improve whatever you do. This is probably explained by the fact that patients enrol in a trial when their pain is at its worst which raises the murky spectre of regression to the mean and the beautiful phenomenon of natural recovery.”

This sort of critical thinking is conspicuously absent from this (and all the other) Southampton handouts. The handout is a superb example of bait and switch: No nonsense about infant colic, innate energy or imaginary subluxations appears in it.

Acupuncture is another interesting case because there is quite a lot of research evidence, in stark contrast to the rest of traditional Chinese medicine, for which there is very little research.

 There is a powerpoint show by Susan Woodhead (though it is labelled British Acupuncture Council). The message is simple and totally uncritical. It works.

(1) Real acupuncture and sham acupuncture have been found to be indistinguishable in many trials. This is the case regardless of whether the sham is a retractable needle (or even a toothpick) in the "right" places, or whether it is real needles inserted in the "wrong" places. The latter finding shows clearly that all that stuff about meridians and flow of Qi is sheer hocus pocus. It dates from a pre-scientific age and it was wrong.

(2) A non-blind comparison of acupuncture versus no acupuncture shows an advantage for acupuncture. But the advantage is usually too small to be of any clinical significance. In all probability it is a placebo effect -it’s hard to imagine a more theatrical event than having someone in a white coat stick long needles into you, like a voodoo doll. Sadly, the placebo effect isn’t big enough to be of much use.

Needless to say, none of this is conveyed to the medical students of Southampton. Instead they are shown crude ancient ideas that date from long before anything was known about physiology as though they were actually true. These folks truly live in some alternative universe. Here are some samples from the acupuncture powerpoint show by Susan Woodhead.

Well this is certainly a "different diagnostic language", but no attempt is made to say which one is right. In the mind of the acupuncurist it seems both are true. It is a characteristic of alternative medicine advocates that they have no difficulty in believing simultaneously several mutually contradictory propositions.

As a final exmple of barminess, just look at the acupuncture points (allegedly) on the ear The fact that it is a favoured by some people in the Pentagon as battlefield acupuncture, is more reminiscent of the mad general, Jack D. Ripper, in Dr Strangelove than it is of science.

There is an equally uncritical handout on acupuncture by Val Hopwood. It’s dated March 2003, a time before some of the most valuable experiments were done.

The handout says "sham acupuncture
is generally less effective than true acupuncture", precisely the opposite of what’s known now. And there are some bits that give you a good laugh, always helpful in teaching. I like

“There is little doubt that an intact functioning nervous system is required for acupuncture to produce
analgesia or, for that matter, any physiological changes”

and

Modern techniques: These include hybrid techniques such as electro-acupuncture . . . and Ryadoraku [sic] therapy and Vega testing.

Vega testing!! That’s been disproved dozens of times (not least by George Lewith). And actually the other made-up nonsense is spelled Ryodoraku.

It’s true that there is a short paragraph at the end of the handout headed "Scientific evaluation of acupuncture" but it doesn’t cite a single reference and reads more like excuses for why acupuncture so often fails when it’s tested properly.

Homeopathy. Finally a bit about that most boring of topics, the laughable medicine that contains no medicine, homeopathy. Caroline Eyles is a member for the Society of Homeopaths, the organisation that did nothing when its members were caught out in the murderous practice of recommending homeopathy for prevention of malaria. The Society of Homeopaths also endorses Jeremy Sherr, a man so crazy that he believes he can cure AIDS and malaria with sugar pills.

The homeopathy handout given to the students has 367 references, but somehow manages to omit the references to their own boss’s work showing that the pills are placebos. The handout has all the sciencey-sounding words, abused by people who don’t understand them.

"The remedy will be particularly effective if matched to the specific/particular characteristics of the individual (the ‘totality’ of the patient) on all levels, including the emotional and mental levels, as well as just the physical symptoms. ‘Resonance’ with the remedy’s curative power will then be at it’s [sic] best."

The handout is totally misleading about the current state of research. It says

"increasing clinical research confirms it’s [sic] clinical effectiveness in treating patients, including babies and animals (where a placebo effect would be hard to justify)."

 The powerpont show by Caroline Eyles shows all the insight of a mediaeval vitalist

Anyone who has to rely on the utterly discredited Jacques Benveniste as evidence is clearly clutching at straws. What’s more interesting about this slide the admission that "reproducibility is a problem -oops, an issue" and that RCTs (done largely by homeopaths of course) have "various methodological flaws and poor external validity". You’d think that if that was the best that could be produced after 200 yours, they’d shut up shop and get another job. But, like aging vicars who long since stopped believing in god, but are damned if they’ll give up the nice country rectory, they struggle on, sounding increasingly desperate.

### Follow-up

The comments that appeared in The Atlantic on this piece were mostly less than enlightening -not quite what one expected of an intellectual magazine. Nevertheless I tried to answer all but the plain abusive comments.

More interesting, though, was an editorial by Jennie Rothenberg Gritz, the Atlantic Senior Editor who asked me to contribute. The Man Who Invented Medical School. It picked up on my mention of Abraham Flexner, and his famous 1910 report [download from Carnegie Foundation] which first put US medial education on a form rational footing. based on science. Now, 100 years later that’s being unpicked both in the USA and here. ms Gritz seemed to think that Flexner would have approved of Dean Ornish. In a response I begged to differ. I’m pretty sure that Felxner would have been furious of he could have seen the reecent march of quackademia, particularly, but not exclusively, in the USA. It is exactly the sort of thing his report set out, successfully, to abolish. He wrote, for example,

“the practitioner is subjected, year in, year out, to the steady bombardment of the unscrupulous manufacturer, persuasive to the uncritical, on the principle that “what I tell you three times is true.” Against bad example and persistent asseveration, only precise scientific concepts and a critical
appreciation of the nature and limits of actual demonstration can protect the young physician.” (Flexner report, 1910, pp 64-65)

It is this very “appreciation of the nature and limits of actual demonstration” that is now being abandoned by the alternative medicine industry. despite the fact that real medicine was in its infancy at the time he w as writing, he was very perceptive about the problems. Perhaps Freedman should read the report.

David Katz seems to have spotted my piece in The Atlantic, and has responded at great length in the Huffington Post (quite appropriate, given the consistent support of HuffPo for nonsense medicine). HuffPo allows only short comments with no links so I’ll reply to him here.

I fear that Dr Katz doth protest a great deal too much. He seems to object to a comment that I made about him in The Atlantic.

“… [He] listed a lot of things he’d tried and which failed to work. His conclusion was not that they should be abandoned, but that we needed a ‘a more fluid concept of evidence.'”

You don’t have to take my word for it. You can take it from the words of Dr Katz.

"What do we do when the evidence we have learned, or if we care to be more provocative, with which we have been indoctrinated, does now fully meet the needs of our patients"

It seems odd to me to regard teaching about how you distinguish what;s true and what isn’t as "indoctrination", though I can understand that knowledge of that subject could well diminish the income of alternative practitioners. You went on to say

"Some years ago the CDC funded us with a million dollars to do what they referred to initially as a systematic review of the evidence base for complementary and alternative medicine,  Anybody who’s ever been involved in systematic reviews knows that’s a very silly thing. . . . Well we knew it was silly but a million dollars sounded real [mumbled] took the money and then we figurered we’d figure out what to do with it [smiles broadly]. That’s what we did ". . .

I do hope you told the CDC that you did not spend the million dollars for the sensible purpose for which it was awarded.

This infusion of calcium, magnesium and D vitamins and vitamin C ameliorates the symptoms of fibromyalgia.  . . .  We did typical placebo controlled randomized double-blind trial for several months . . . we saw an improvement in both our treatment and placebo groups . . .

You then describe how you tested yoga for asthma and homeopathy for attention deficit hyperactivity disorder, Neither of them worked either. Your reaction to this string of failures was just to say “we need a more fluid concept of evidence”

After telling an anecdote about one patient who got better after taking homeopathic treatment you said £I don’t care to get into a discussion of how, or even whether, homeopathy works”.  Why not?  It seems it doesn’t matter much to you whether the things you sell to patients work or not.

You then went on to describe quite accurately that anti-oxidants don’t work and neither do multivitamin supplements for prevention of cardiovascular problems,  And once again you fail to accept the evidence, even evidence you have found yourself. Your response was

“So here too is an invitation to think more fluidly about of evidence. Absence of evidence is not evidence of absence.”

That last statement is the eternal cry of every quack.  It’s true, of course, but that does not mean that absence of evidence gives you a licence to invent the answer.  But inventing the answer is what you do, time after time, You seem quite incapable of saying the most important thing that anyone in your position should. I don’t know the answer.
