No, I kid you not!

This abstract was actually published in the leading chiro-journal. The authors include three professors from the Canadian Memorial Chiropractic College, Research, Toronto, Canada. Its title is impressive but made my alarm bells ring a bit:

A Randomized Pragmatic Clinical Trial of Chiropractic Care for Headaches With and Without a Self-Acupressure Pillow.

And the actual texts does not disappoint those looking for of pure pseudo-science:

The purpose of this study was to determine if the addition of a self-acupressure pillow (SAP) to typical chiropractic treatment results in significantly greater improvement in tension-type and cervicogenic headache sufferers.

METHODS:

A pragmatic randomized clinical trial was conducted in a chiropractic college teaching clinic. Thirty-four subjects, including tension-type and cervicogenic headache sufferers, 21 to 60 years of age, male or female, completed the study. Group A (n = 15) received typical chiropractic care only (manual therapy and exercises), and group B (n = 19) received typical chiropractic care with daily home use of the SAP. The intervention period was 4 weeks. The main outcome measure was headache frequency. Satisfaction and relief scores were obtained from subjects in the SAP group. Analysis of variance was used to analyze the intergroup comparisons.

RESULTS:

Owing to failure of randomization to produce group equivalence on weekly headache frequency, analysis of covariance was performed showing a trend (P = .07) favoring the chiropractic-only group; however, this was not statistically significant. Group A obtained a 46% reduction of weekly headache frequency (t = 3.1, P = .002; d = 1.22). The number of subjects in group A achieving a reduction in headaches greater than 40% was 71%, while for group B, this was 28%. The mean benefit score (0-3) in group B of the use of the SAP was 1.2 (.86). The mean satisfaction rating of users of the SAP was 10.4 (2.7) out of 15 (63%).

CONCLUSION:

This study suggests that chiropractic care may reduce frequency of headaches in patients with chronic tension-type and cervicogenic headache. The use of a self-acupressure pillow (Dr Zaxx device) may help those with headache and headache pain relief as well as producing moderately high satisfaction with use.

Where to begin?

Perhaps it is best, if I simply concentrated on the bizarre research question: is chiropractic care plus the largely uncontrolled use of an ‘acupressure cushion’ better than chiropractic care alone? To savour the lunacy of it, we need to consider that:

  • chiropractic is not plausible;
  • chiropractic care is not proven to be effective for headaches;
  • acupressure is not plausible;
  • acupressure is not proven to be effective;
  • a self-administered acupressure cushion is also unproven and even less plausible;

This, I fear, renders the study one of the most nonsensical trials I have seen for a very long time. To make the bonanza in pseudo-science complete, the article is supplemented with a most bizarre conclusion about the effectiveness of chiropractic (which, of cause, cannot be examined in a trial of chiro vs chiro).

All this leads me to fear that:

  • the best journal of chiropractic is rubbish;
  • a professorship in a chiro school may not mean that the professor has the slightest idea about research methodology;
  • chiropractors will try to squeeze a conclusion that is favourable for their trade even out of a dead horse.

I am probably more used to nonsensical statements by promoters of alternative medicine than the average person. But the ‘ALTERNATIVE MEDICINE ZONE’ just broke my BS-meter. Here are a few samples from their most remarkable website, all relating to homeopathy:

There has always been a debate whether allopathic treatment methods of the modern age are more beneficial or are the natural homeopathic treatment ways more reliable. The goal of healing the sick is the same in both these groups of treatment, but there is a strong contrast in the methods use, the ideology behind the treatment and the detailed theories. The following is a detailed comparison between homeopathy and Allopathy for those who wish to pick between the two:

Beliefs

Allopathic practitioners aim to target that part of the body that has been affected by a problem or disease and they do so by identifying the causing agent. On the other hand, in Homeopathy, doctors believe that emotional stress or psychological reasons make the body more susceptible to diseases and use more of a holistic approach of treatment.

Medicines

Allopathic doctors make use of those medications which are produced by pharma companies or are man-made. On the other hand, Homeopathy uses natural supplements and cures such as herbs, dietary changes and other such ways to cure a disease. Allopathic doctors use an aggressive approach whereas homeopathic doctors consider one dose enough to treat a disease.

Surgeries

While on one hand, allopathic doctors consider surgeries to be very important for removal of tumors etc. or correcting problems inside the body, Homeopathic doctors almost never use surgery as a treatment method. Only when certain tissue in the body has become seriously damaged they practice this technique.

Allopathic surgeons heavily rely on surgical procedures in case of serious diseases which cannot be cured by medicines or any other approach. Homeopathic doctors try to treat each and every condition with a natural method or by recommending strong dietary changes.

Origins

Homeopathy is basically based on beliefs of German Physician Samuel Hahnemann whereas Allopathic system of treatment or cure of diseases is based on the principles of the ancient Greeks, for example Hippocrates. Allopathic is considered to be regular medicine in many countries such as US but Homeopathy is argued to be a natural and holistic way of cure.

Controversy

Both these schools of medicine consider the other to be non-beneficial. Homeopathy thinks that allopathic medicines tend to make people even sicker in the long run whereas Allopathy doctors believe that Homeopathy only uses Placebo as its mechanism to cure people. Supporters of both schools are often seen defending their preferred method of treatment.

The ‘ALTERNATIVE MEDICINE ZONE’ also does not shy away from giving concrete medical advice on their website. Two examples will have to suffice:

HOMEOPATHY FOR SHINGLES

Compare to anti-viral medicines, homeopathy has proved more effective for shingles and chicken pox. It offers rapid and successful approach in treating this infection. People with weak immune system are more prone to get shingles. Homeopathy medicines influence the immune system efficiently from within and improve body’s healing capacity. The homeopathy medicines are also capable of defusing pain, discomfort in body due to shingle. It also refrain shingles from spreading.

HOMEOPATHY FOR PILES

The homeopathic treatment is considered much better than surgery because it corrects the problem from the root which is not the case in surgery. Homeopathy is considered very useful in the early cases of piles and can help in complete healing. However as the problem becomes complex, it can only help in the healing of the symptoms.

Both articles finish by giving a list of homeopathic remedies that are recommended for the two conditions.

So there we have it!

My BS-meter has just broken.

Who can I sue?

Having been in contact with homeopaths most of my life, I had almost come to the conclusion that they tend to be more than a little short of a sense of humour. Well, I was wrong! I first realised my error when I came across this website. Under the heading ‘WHY USE HOMEOPATHICS?’, it lists 6 reasons which are undeniably full of humour, satire and irony. Here they are:

  • Homeopathy is extremely effective. When the correct remedy is taken, results can be rapid, complete and permanent.
  • Homeopathy is completely safe. Even babies and pregnant women can use Homeopathy without the danger of side effects. Homeopathic remedies can also be taken alongside other medication without producing unwanted side effects.
  • Homeopathy is natural. Homeopathic remedies are normally based on natural ingredients.
  • Homeopathy works in harmony with your immune system, unlike some conventional medicines which suppress the immune system. (For example, cough medicines suppress the cough reflex, which is your body’s attempt to clear the lungs)
  • Homeopathic remedies are not addictive – once relief is felt, you should stop taking them. If no relief is felt, you are probably taking the wrong homeopathic remedy.
  • Homeopathy is holistic. It treats all the symptoms as one, which in practical terms means that it addresses the cause, not the symptoms. This often means that symptoms tackled with Homeopathy do not recur.

This is hilarious, but perhaps not as funny as this website of the ‘British Homeopathic Dental Association’ (yes, you read correctly: there are dentists who use homeopathy!) providing ‘six good reasons why you should visit a homeopathic dentist’:

  1. Because they treat patients holistically
  2. Homeopathic remedies are effective and have no unpleasant side effects
  3. There are remedies which stop swelling and pain after injections and extractions
  4. There are remedies which reduce the pain and swelling of dental abscesses
  5. There are remedies which alleviate toothache
  6. There are remedies which which cure ulcers and cold sores and many more

You might think that these are isolated cases of humour. If so, I recommend you go on the internet and find what else homeopathy offer for our amusement. There is more laughter hidden in the homeopathic websites that you can possibly imagine. Here is another example: on his homepage, a homeopath clearly states that the following list of conditions are curable/treatable with homeopathy:

You have to admit, this is funny! No?

Perhaps this website will make you giggle:

The online procedure for homeopathic treatment is straightforward, and only requires four simple steps. Please note that your second Follow Up Consultation is absolutely free.

  1. First, please send me some basic information about yourself, so that I can analyse your case. In my reply I will inform you if Homeopathic treatment can be successful personally for you. This step is absolutely FREE.
  2. After receiving my reply, you may decide whether you wish to continue with treatment. You can then make a payment and you will be sent a First Consultation Form, to complete via email, which you should fill in carefully and send back. This will be a detailed questionnaire.
  3. Please allow two days for me to read your form, from which I will be able to work out your case. I will then send you a reply, with written report regarding your general state of health, pointing possible weaknesses and a Homeopathic prescription for Homeopathic remedies with full explanation of how to use them and the reason why they are prescribed.
  4.  After your initial period of using homeopathic medication is over / usually 4-5 weeks/, you will then be asked to fill in a Follow Up Consultation Form, which will be sent to you. This is to see how you have got on with the treatment.

From here, the fourth step is repeated until you are treated. As stated above, your second Follow Up Consultation is absolutely free. This is to encourage you to stay on your course of treatment, as often (not always), you will need some patience to see lasting results. Your health is my first priority.

You will also have phone and email support from me at any time while you are using this service.

I am only ever a phone-call away if you have any queries and I do not charge for this service.

There you are, I am certain that nobody can deny it: THIS IS COMIC GOLD!!!

Good humour carries a strong element of satire aimed at “the absurdity of everyday life”. And surely these homeopaths are spot on.

If you start reading the literature on chiropractic, you are bound to have surprises. The paucity of rigorous and meaningful research is one of them. I am constantly on the look-out for such papers but am regularly frustrated. Over the years, I got the impression that chiropractors tend to view research as an exercise in promotion – that is promotion of their very own trade.

Take this article, for instance. It seems to be a systematic review of chiropractic for breastfeeding. This is an interesting indication; remember: in 1998, Simon Singh wrote in the Guardian this comment “The British Chiropractic Association claims that their members can help treat children with colic, sleeping and feeding problems, frequent ear infections, asthma and prolonged crying, even though there is not a jot of evidence. This organisation is the respectable face of the chiropractic profession and yet it happily promotes bogus treatments.” As a consequence, he got sued for libel; he won, of course, but ever since, chiropractors across the world are trying to pretend that there is some evidence for their treatments after all.

The authors of the new review searched Pubmed [1966-2013], Manual, Alternative and Natural Therapy Index System (MANTIS) [1964-2013] and Index to Chiropractic Literature [1984-2013] for the relevant literature. The search terms utilized “breastfeeding”, “breast feeding”, “breastfeeding difficulties”, “breastfeeding difficulty”, “TMJ dysfunction”, “temporomandibular joint”, “birth trauma” and “infants”, in the appropriate Boolean combinations. They also examined non-peer-reviewed articles as revealed by Index to Chiropractic Literature and conducted a secondary analysis of references. Inclusion criteria for their review included all papers on breastfeeding difficulties regardless of peer-review. Articles were excluded if they were not written in the English language.

The following articles met the inclusion criteria: 8 case reports, 2 case series, 3 cohort studies and 6 manuscripts (5 case reports and a case series) that involved breastfeeding difficulties as a secondary complaint. The findings revealed a “theoretical and clinical framework based on the detection of spinal and extraspinal subluxations involving the cervico-cranio-mandibular complex and assessment of the infant while breastfeeding.”

Based on these results, the authors concluded that chiropractors care of infants with breastfeeding difficulties by addressing spinal and extraspinal subluxations involving the cervico-cranio-mandibular complex.

Have I promised too much?

I had thought that chiropractors had abandoned the subluxation nonsense! Not really, it seems.

I had thought that systematic reviews are about evidence of therapeutic effectiveness! Not in the weird world of chiropractic.

I would have thought that we all knew that ‘chiropractors care of infants with breastfeeding difficulties’ and do not need a review to confirm it! Yes, but what is good for business deserves another meaningless paper.

I would have thought that the conclusions of scientific articles need to be appropriate and based on the data provided! It seems that, in the realm of chiropractic, these rules do not apply.

An appropriate conclusion should have stated something like THERE IS NO GOOD EVIDENCE THAT CHIROPRACTIC CARE AIDS BREASTFEEDING. But that would have been entirely inappropriate from the chiropractic point of view because it is not a conclusion that promotes the sort of quackery most chiropractors rely upon for a living. And the concern over income is surely more important than telling the truth!

Hurray, I can hear the Champagne corks popping: this month is ‘National Chiropractic Months’ in the USA – a whole month! This has depleted my stock of the delicious fizz already in the first three days.

Now that my bottles are empty (is there a chiropractic cure for a hang-over?), I must find other ways to celebrate. How about a more sober look at what has been published in the medical literature on chiropractic during the last few days?

A quick look into Medline identifies several articles of interest. The very first one is a case-report:

Spinal epidural hematoma (SEH) occurring after chiropractic spinal manipulation therapy (CSMT) is a rare clinical phenomenon. Our case is unique because the patient had an undiagnosed cervical spinal arteriovenous malformation (AVM) discovered on pathological analysis of the evacuated hematoma. Although the spinal manipulation likely contributed to the rupture of the AVM, there was no radiographic evidence of the use of excessive force, which was seen in another reported case. As such, patients with a known AVM who have not undergone surgical intervention should be cautioned against symptomatic treatment with CSMT, even if performed properly. Regardless of etiology, SEH is a surgical emergency and its favorable neurological recovery correlates inversely with time to surgical evacuation.

This is important, I think, in more than one way. Many chiropractors simply deny that their manipulations cause serious complications of this nature. Yet such cases are being reported with depressing regularity. Other chiropractors claim that excessive force is necessary to cause the damage. This paper seems to refute this notion quite well, I think.

But let’s not be inelegant and dwell on this unpleasant subject; it might upset chiros during their month of celebration.

The next article fresh from the press is a survey – chiropractors are very fond of this research tool, it seems. It produced a lot of intensely boring data – except for one item that caught my eye: the authors found that ‘virtually all Danish chiropractors working in the primary sector made use of manipulation as one of their treatment modalities.’

Why is that interesting? Whenever I point out that there is no good evidence that chiropractic manipulations generate more good than harm, chiropractors tend to point out that they do so much more than that. Manipulations are not administered to all their patients, they say. This survey is a reminder (there is plenty more evidence on this issue) of the fact that the argument is not very convincing.

Another survey which has just been published in time for the ‘celebratory month’ is worth mentioning. It reports the responses of patients to questions about chiropractic by providing the ‘positive angle’, e.g.: ‘Most (61.4%) respondents believed that chiropractic care was effective at treating neck and back pain…’ Just for the fun of it, I thought it might be worth doing the opposite: 39% did not believe that chiropractic care was effective at treating neck and back pain… If we use this approach, the new survey also indicates that about half of the respondents did not think chiropractors were trustworthy, and 86% have not consulted a chiropractor within the last year.

Oh, so sorry – I did not mean to spoil the celebrations! Better move on then!

A third survey assessed the attitudes of Canadian obstetricians towards chiropractic. Overall, 70% of respondents did not hold a positive views toward chiropractic, 74% did not agree that chiropractic had a role in treatment of non-musculoskeletal conditions, 60% did not refer at least some patients for chiropractic care each year, and comments of the obstetricians revealed concerns regarding safety of spinal manipulation and variability among chiropractors.

And now I better let you get on with your well-deserved celebrations and look for another bottle!

When it comes to alternative medicine, the public relies heavily on the writings of health journalists. We therefore have to count ourselves lucky to have some that are outstanding in their ability to inform the public honestly, objectively and responsibly. Here is an excerpt of what one particularly gifted and ethical heath journalist (and consultant!!!) just published regarding the treatment of babies and kids on a highly visible, popular website:

Homeopathy, or homeopathic medicine, is based on the principle that “like cures like.” Instead of treating an individual’s illness, homeopathy treats individual symptoms with substances from plants and minerals that are highly diluted and “succussed,” or shaken to release energy, said Sara Chana Silverstein, a homeopath, master herbalist and an international board-certified lactation consultant…Although homeopathy isn’t meant to replace Western medicine, it can be a complementary or alternative approach for ailments like colds, the stomach flu and teething. For example, if your pediatrician has diagnosed your baby with an upper respiratory infection, there’s not much you can do other than offer lots of fluids, rest and possibly acetaminophen or ibuprofen. In this case, a homeopathic remedy might help. Plus, since antibiotic overuse and antimicrobial resistance remain a major concern in the U.S., and antibiotics often have side effects, homeopathy could help heal without the need for a prescription. In fact, a study in the journal Homeopathy found that homeopathy for ear infections was just as effective as conventional treatment but patients in the homeopathic group had a faster improvement in symptoms. Although some studies show promising results, more research is needed to determine who homeopathic remedies work best for and in what situations, said Dr. Hilary McClafferty, chair of the American Academy of Pediatrics’ Section on Complementary and Integrative Medicine…

“In the United, States, the homeopathic products that carry the label, HPUS

Homeopathic Pharmacopeia of the United States— are prepared with a very standardized, procedural monograph. So there is a map and regulations that ensure what’s on the label is what’s in the bottle,” McClafferty said…The only adverse effect of homeopathy, according to Silverstein, is that if a baby consumed a remedy too frequently, such as every hour for 10 hours, they would “prove” the remedy, or create the symptoms the remedy was trying to heal. “But if you gave it to a child 3 times a day at a low dose, personally I do not believe it could injure a child in anyway whatsoever,” she said…Your best bet is to see a trained homeopath who will target individual symptoms and give you pellets in the size that’s appropriate for your child’s age, Silverstein said. The bottom line when it comes to deciding between homeopathy, a medication or another remedy? “You want to be well educated, conservative and in touch with your pediatrician,” McClafferty said.

As I said: outstanding!

With so much sound information about homeopathy and its merits in the treatment of childhood conditions, we are inclined to forgive the few tiny errors and marginally misleading statements that might require corrections such as:

  • homeopathy is very much meant as a replacement of conventional medicine by its inventor Hahnemann who was adamant that it must not be combined with other treatments because it is the only true healing art;
  • there is no good evidence that homeopathy is anything else than a placebo for children or, indeed, for anyone else;
  • the study in the journal ‘Homeopathy’ was lousy and does not allow any conclusions whatsoever about the effectiveness of homeopathy;
  • to state “some studies show promising results” is very misleading; the totality of the reliable evidence is negative;
  • more research is not needed to determine who benefits from homeopathy; there is no longer a debate about homeopathy within science;
  • the label of a typical homeopathic preparation does not tell you what’s in the bottle, at best it tells you what used to be there;
  • the main risk of homeopathy is that diseases are not treated effectively; in this way, homeopathy can kill.

Yes, these are but very minor flaws, I know. They should not distract from this journalist’s great achievement of getting her brilliantly informative article read by the widest possible audience. If Prince Charles offered an award for the best science writer of the year (why has he not yet thought of this publicity stunt?), she would certainly be a candidate.

This seems to be the question that occupies the minds of several homeopaths.

Amazed?

So was I!

Let me explain.

In 1997, Linde et al published their now famous meta-analysis of clinical trials of homeopathy which concluded that “The results of our meta-analysis are not compatible with the hypothesis that the clinical effects of homeopathy are completely due to placebo. However, we found insufficient evidence from these studies that homeopathy is clearly efficacious for any single clinical condition. Further research on homeopathy is warranted provided it is rigorous and systematic.”

This paper had several limitations which Linde was only too happy to admit. The authors therefore conducted a re-analysis which, even though published in an excellent journal, is rarely cited by homeopaths. Linde et al stated in their re-analysis of 2000: “there was clear evidence that studies with better methodological quality tended to yield less positive results.” It was this phenomenon that prompted me and my colleague Max Pittler to publish a ‘letter to the editor’ which now – 15 years later – seems the stone of homeopathic contention.

A blog-post by a believer in homeopathy even asks the interesting question: Did Professor Ernst Sell His Soul to Big Pharma? It continues as follows:

Edzard Ernst is an anti-homeopath who spent his career attacking traditional medicine. In 1993 he became Professor of Complementary Medicine at the University of Exeter. He is often described as the first professor of complementary medicine, but the title he assumed should have fooled no-one. His aim was to discredit medical therapies, notably homeopathy, and he then published some 700 papers in ‘scientific’ journals to do so.

Now, Professor Robert Hahn, in his blog, has made an assessment of the quality of his work… In the interests of the honesty and integrity in science, it is an important assessment. It shows, in his view, how science has been taken over by ideology (or as I would suggest, more accurately, the financial interests of Big Corporations, in this case, Big Pharma). The blog indicates that in order to demonstrate that homeopathy is ineffective, over 95% of scientific research into homeopathy has to be discarded or removed! 

So for those people who, like myself, cannot read the original German, here is an English translation of the blog…

“I have never seen a science writer so blatantly biased as Edzard Ernst: his work should not be considered of any worth at all, and discarded” finds Sweden’s Professor Robert Hahn, a leading medical scientist, physician, and Professor of Anaesthesia and Intensive Care at the University of Linköping, Sweden.

Hahn determined therefore to analyze for himself the ‘research’ which supposedly demonstrated homeopathy to be ineffective, and reached the shocking conclusion that:

“only by discarding 98% of homeopathy trials and carrying out a statistical meta-analysis on the remaining 2% negative studies, can one ‘prove’ that homeopathy is ineffective”.

In other words, all supposedly negative homeopathic meta-analyses which opponents of homeopathy have relied on, are scientifically bogus…
 
 Who can you trust? We can begin by disregarding Edzard Ernst. I have read several other studies that he has published, and they are all untrustworthy. His work should be discarded… 

In the case of homeopathy, one should stick with what the evidence reveals. And the evidence is that only by removing 95-98% of all studies is the effectiveness of homeopathy not demonstrable…

So, now you are wondering, I am sure: HOW MUCH DID HE GET FOR SELLING HIS SOUL TO BIG PHARMA?

No? You are wondering 1) who this brilliant Swedish scientist, Prof Hahn, is and 2) what article of mine he is criticising? Alright, I will try to enlighten you.

PROFESSOR HAHN

Here I can rely on a comment posted on my blog some time ago by someone who can read Swedish (thank you Bjorn). He commented about Hahn as follows:

A renowned director of medical research with well over 300 publications on anesthesia and intensive care and 16 graduated PhD students under his mentorship, who has been leading a life on the side, blogging and writing about spiritualism, and alternative medicine and now ventures on a public crusade for resurrecting the failing realm of homeopathy!?! Unbelievable!

I was unaware of this person before, even if I have lived and worked in Sweden for decades.

I have spent the evening looking up his net-track and at his blog at roberthahn.nu (in Swedish).

I will try to summarise some first impressions:

Hahn is evidently deeply religious and there is the usual, unmistakably narcissistic aura over his writings and sayings. He is religiously confident that there is more to this world than what can be measured and sensed. In effect, he seems to believe that homeopathy (as well as alternative medical methods in general) must work because there are people who say they have experienced it and denying the possibility is akin to heresy (not his wording but the essence of his writing).

He has, along with his wife, authored at least three books on spiritual matters with titles such as (my translations) “Clear replies from the spiritual world” and “Connections of souls”.

He has a serious issue with skeptics and goes on at length about how they are dishonest bluffers[sic] who willfully cherry-pick and misinterpret evidence to fit their preconceived beliefs.

He feels that desperate patients should generally be allowed the chance that alternative methods may offer.

He believes firmly in former-life memories, including his own, which he claims he has found verification for in an ancient Italian parchment.

His main arguments for homeopathy are Claus Linde’s meta analyses and the sheer number of homeopathic research that he firmly believes shows it being superior to placebo, a fact that (in his opinion) shows it has a biological effect. Shang’s work from 2005 he dismisses as seriously flawed.

He also points to individual research like this as credible proof of the biologic effect of remedies.

He somewhat surprisingly denies recommending homeopathy despite being convinced of its effect and maintains that he wants better, more problem oriented and disease specific studies to clarify its applicability. (my interpretation)

If it weren’t for his track record of genuine, acknowledged medical research and him being a renowned authority in a genuine, scientific medical field, this man would be an ordinary, religiously devout quack.

What strikes me as perhaps telling of a consequence of his “exoscientific” activity, is that Hahn, who holds the position of research director at a large city trauma and emergency hospital is an “adjungerad professor”, which is (usually) a part time, time limited, externally financed professorial position, while any Swedish medical doctor with his very extensive formal merits would very likely hold a full professorship at an academic institution.

END OF QUOTE

MY 2000 PAPER THAT SEEMS TO IRRITATE HAHN

This was a short ‘letter to the editor’ by Ernst and Pittler published in the J Clin Epidemiol commenting on the above-mentioned re-analysis by Linde et al which was published in the same journal. As its text is not available on-line, I re-type parts of it here:

In an interesting re-analysis of their meta-analysis of clinical trials of homeopathy, Linde et al conclude that there is no linear relationship between quality scores and study outcome. We have simply re-plotted their data and arrive at a different conclusion. There is an almost perfect correlation between the odds ratio and the Jadad score between the range of 1-4… [some technical explanations follow which I omit]…Linde et al can be seen as the ultimate epidemiological proof that homeopathy is, in fact, a placebo.

And that is, as far as I can see, the whole mysterious story. I cannot even draw a conclusion – all I can do is to ask a question:

DOES ANYONE UNDERSTAND WHAT THEY ARE GOING ON ABOUT?

The story is all over: at a symposium last weekend, 29 German homeopaths ended up in hospital after ingesting the powerful hallucinogenic drug, 2C-E, also known as Aqua Rust. You can read it here or here or here or here, for instance.

The events are a bit nebulous, and most newspapers got it at least partly wrong. The group seems to have been composed of not just homeopaths but also ‘Heilpraktiker’, the German lay healers who usually mix all sorts of alternative therapies. They did take the drug – which one exactly has not yet been verified – and became acutely ill. A huge amount of ambulances and staff came to their rescue and took them all to hospital where they seem to be still recovering. Police is understandably keen to talk to them.

On Twitter and elsewhere, people have been making fun at these poor health care professionals. I think this is hardly called for and certainly less than kind. Other, more empathetic experts have suggested that these men and women have engaged in a self-experiment. I always like to see the good in people, particularly in homeopaths and therefore like this idea.

What if, as has been suggested, these people actually did a homeopathic proving on Aqua Rust? In this case, they are my heroes! Not just because they sacrificed their own health in the interest of medicine, but they seem to have found an important, I would even say ground-breaking new cure.

Homeopathic provings are the corner-stone of homeopathy; they are the tool used by homeopaths to identify which remedy is suited for which condition/patient. Provings work as follows: several healthy volunteers take a remedy in a high concentration; subsequently they record their symptoms in much detail; these symptoms then constitute the ‘drug picture’ of the remedy tested; and when a patient complains of similar symptoms, she will be cured with a high dilution of this very remedy. This is what the prime law of homeopathy is all about: LIKE CURES LIKE.

So what have our German pioneers discovered last weekend? They took the Aqua Rust (or whatever else the police will find in their system) and were reported to all start talking utter nonsense. But this is nothing short of sensational! According to the rules of homeopathy, the drug they took can now be highly diluted and shaken vigorously many times – and we have a cure…for what?

AGAINST HOMEOPATHY, OF COURSE!

The number one characteristic of homeopathy is that its proponents talk utter nonsense. Give them their newly discovered remedy and they will be cured. Simple!

In my mind, there is little doubt, these German homeopathic heroes need to be nominated for the next Nobel prize: homeopathy has plagued the world since 200 years, and nobody has yet found a cure for it. These courageous and dedicated healers sacrificed not just their weekend, but also their well-being and health to find one – and they have done it!

Homeopathy will finally be an oddity of the past – well worth a Nobel prize, I’d say.

A recent article promised to provide details of the ’10 most mind-numbingly stupid alternative therapies’. Naturally I was interested what these might be. In descending order they are, according to the author of the most enjoyable piece:

10 VEGA TESTING

9 REIKI

8 CRYSTAL HEALING

7 URINE THERAPY

6 DETOXIFYING FOOT PADS

5 WHEAT-GRASS ENEMAS

4 PSYCHIC SURGERY

3 OZONE THERAPY

2 CUPPING THERAPY

1 HOMEOPATHY

This is quite a list, I have to admit. Despite some excellent choices, I might disagree with a few of them. Detoxifying foot pads will take care of a common and most annoying problem: smelly feet; therefore it cannot be all bad. And drinking your own urine can even be a life-saver! Lets assume someone has a kidney or bladder cancer. Her urine might, at one stage, be bright red with blood. The urine therapy enthusiast would realise early that something is wrong with her, go and see a specialist, get early treatment and save her life. No, no no, I cannot fully condemn urine therapy!

The other thing with the list is that one treatment which is surely mind-bogglingly stupid is missing: CHELATION THERAPY.

I have previously written about this form of treatment and pointed out that some practitioners of alternative medicine (doctors, naturopaths, chiropractors and others) earn a lot of money claiming that chelation therapy (a well-established mainstream treatment for acute heavy metal poisoning) is an effective therapy for cardiovascular and many other diseases. However, this claim is both implausible and not evidence-based. Several systematic reviews of the best evidence concluded less than optimistically:

…more controlled studies are required to determine the efficacy of chelation therapy in cardiovascular disease before it can be used broadly in the clinical setting.

The best available evidence does not support the therapeutic use of EDTA chelation therapy in the treatment of cardiovascular disease.

Given the potential of chelation therapy to cause severe adverse effects, this treatment should now be considered obsolete.

The available data do not support the use of chelation in cardiovascular diseases.

Despite all this, the promotion of chelation continues unabated. An Australian website, ironically entitled ‘LEADERS IN INTEGRATIVE MEDICINE’, might stand for many others when it informs its readers about chelation therapy. Here is a short passage:

Chelation therapy has the ability to remove the calcium from artery plaques as well as remove toxic ions, reduce free radical damage and restore circulation to all tissues of the body. A growing number of physicians use chelation therapy to reverse the process of atherosclerosis (hardening of the arteries) and as an alternative to angioplasty and bypass surgery.

Chelation therapy is a treatment to be considered for all conditions of reduced blood flow (coronary artery disease, cerebral vascular disease, peripheral vascular disease, angina, vertigo, tinnitus, senility), any situations of heavy metal toxicity or tissue overload and various chronic immune system disorders such as rheumatoid arthritis. Intravenous vitamin C is useful for the treatment of chronic and acute infections, fatigue, pre- and post-surgery and to boost the immune system while undergoing cancer therapies.

Not bad, isn’t it. How come such mind-numbing stupidity escaped the author of the above article? Was it an oversight? Was the choice just too overwhelming? Or did he not think chelation was all that funny? I ought to mention that it is not at all harmless like sampling your own urine or having a Reiki healer sending some ‘healing energy’.

Whatever the reason, I hope for an up-date of the list, he will consider chelation as a seriously mind-numbing contender.

Conventional cough syrups do not have the best of reputations – but the repute of homeopathic cough syrups is certainly not encouraging. So what should one do with such a preparation? Forget about it? No, one conducts a clinical trial, of course! Not just any old trial but one where science, ethics and common sense are absent. Here are the essentials of a truly innovative study that, I think, has all of these remarkable qualities:

The present prospective observational study investigated children affected by wet acute cough caused by non-complicated URTIs, comparing those who received the homeopathic syrup versus those treated with the homeopathic syrup plus antibiotic. The aims were: 1) to assess whether the addition of antibiotics to a symptomatic treatment had a role in reducing the severity and duration of acute cough in a pediatric population, as well as in improving cough resolution; 2) to verify the safety of the two treatments. Eighty-five children were enrolled in an open study: 46 children received homeopathic syrup alone for 10 days and 39 children received homeopathic syrup for 10 days plus oral antibiotic treatment (amoxicillin/clavulanate, clarithromycin, and erythromycin) for 7 days. To assess cough severity we used a subjective verbal category-descriptive (VCD) scale. Cough VCD score was significantly (P < 0.001) reduced in both groups starting from the second day of treatment (−0.52 ± 0.66 in the homeopathic syrup group and −0.56 ± 0.55 in children receiving homeopathic syrup plus oral antibiotic treatment). No significant differences in cough severity or resolution were found between the two groups of children in any of the 28 days of the study. After the first week (day 8) cough was completely resolved in more than one-half of patients in both groups. Two children (4.3 %) reported adverse effects in the group treated with the homeopathic syrup alone, versus 9 children (23.1 %) in the group treated with the homeopathic syrup plus antibiotics (P = 0.020).

Conclusions

Our data confirm that the homeopathic treatment in question has potential benefits for cough in children as well, and highlight the strong safety profile of this treatment. Additional antibiotic prescription was not associated with a greater cough reduction, and presented more adverse events than the homeopathic syrup alone.

Let us be clear about what has happened here. I think, the events can be summarised as follows:

  • the researchers come across a homeopathic syrup (anyone who understands respiratory problems and/or therapeutics would be more than a little suspicious of this product, but this team is exceptional),
  • they decide to do a trial with it (a decision which would make some ethicists already quite nervous, but the ethics committee is exceptional too),
  • the question raises, what should the researchers give to the control group?
  • someone has the idea, why not compare our dodgy syrup against something that is equally dodgy, perhaps even a bit unsafe?
  • the researchers are impressed and ask: but what precisely could we use?
  • let’s take antibiotics; they are often used for acute coughs, but the best evidence fails to show that they are helpful and they have, of course, risks,
  • another member of the team adds: let’s use children, they and their mothers are unlikely to understand what we are up to,
  • the team is in agreement,
  • Boiron, the world’s largest producer of homeopathic products, accepts to finance the study,
  • a protocol is written,
  • ethics approval is obtained,
  • the trial is conducted and even published by a journal with the help of peer-reviewers who are less than critical.

And the results of the trial? Contrary to the authors’ conclusion copied above, they show that two bogus treatments are worse that one.

BOB’S YOUR UNCLE!

EVERYONE SEEMS HAPPY: THE RESEARCHERS CAN ADD AN ARTICLE TO THEIR PUBLICATION LIST, BOIRON HAS MORE ‘EVIDENCE’ IN FAVOUR OF HOMEOPATHY, AND THE ETHICS COMMITTEE SLEEP JUST AS SOUNDLY AS THE PEER-REVIEWERS.
