In Germany, homeopathy had a free ride for a very long time. In recent years, however, several doctors, pharmacists, scientists, etc. have started opposing the fact that the public has to pay for ineffective treatments such as homeopathics. As a consequence, homeopaths have begun to fight back. The weapons they chose are often not the most subtle. Now they seem to have reached a new low; the Board of the German Central Association of Homeopathic Physicians (DZVhÄ) has sent an open letter to the Board of the German Society of Internal Medicine (DGIM) and to the participating colleagues of the 127th Congress of the DGIM from April 17 – 20, 2021 in an attempt to stop an invited lecture of a critic of homeopathy.

Here is my translation of the letter:

Dear colleagues on the board of the DGIM,

We were very surprised to read that an ENT colleague will speak on homeopathy at the 127th Congress of Internal Medicine. Dr. Lübbers is known up and down the country as a media-active campaigner against homeopathy. His “awakening experience” he had, according to his own account, when he had to fish homeopathic pills out of the ear of a child with otitis, since then he is engaged – no: not for better education, in the mentioned case of the parents or other users – against the method homeopathy (which was certainly not “guilty” of the improper application!).

It has surely not escaped you that in all media again and again only a small handful of self-proclaimed “experts” – all from the clique of the skeptic movement! – are heard on the subject of homeopathy. A single (!) fighter against homeopathy is a physician who completed her training in homeopathy and practices for a time as a homeopath. All the others come from non-medical and other occupational groups. In contrast, there are several thousand medical colleagues throughout Germany who stand on the ground of evidence-based medicine, have learned conventional medicine, implement it in their practices, and have completed a recognized continuing education program in homeopathy.

In the German Central Association of Homeopathic Physicians – the oldest medical professional association in Germany – 146 qualified internists are currently registered as members, in addition to numerous other medical specialists, all of whom are actively practicing medicine.

Question: Why does the German Society for Internal Medicine invite an ENT specialist, of all people, who lectures on homeopathy without any expertise of his own? Why not at least a specialist colleague in internal medicine? Or even a colleague who could report on the subject from her own scientific or practical experience? For example, on the topic of “hyperaldosteronism,” would you also invite a urologist or orthodontist? And if so, why?

Dear Board of Directors of the DGIM: As an honorary board member of the German Central Association of Homeopathic Physicians e.V.. (DZVhÄ) – and a specialist in internal medicine – I am quite sure that we could immediately name several colleagues with sufficient expertise as homeopathically trained and experienced internists, if you are really interested in a solid and correct discourse on the subject of homeopathy. Under the above-mentioned circumstances, there is, of course, rather the suspicion that it should not be about, but rather exclusively against homeopathy.

If it is planned for a later congress, e.g. in 2022, to deal again with the topic of homeopathy in a truly professionally well-founded and possibly even more balanced form: please contact us at any time! As medical colleagues, we are very interested in a fair and unprejudiced professional discourse.

Yours sincerely

Dr. med. Ulf Riker, Internist – Homeopathy – Naturopathy

2nd chairman DZVhÄ / 1st chairman LV Bayern

________________

What are Riker and the DZVhÄ trying to say with this ill-advised, convoluted, and poorly written letter?

Let me try to put his points a little clearer:

  • They are upset that the congress of internists invited a non-homeopath to give a lecture about homeopathy.
  • The person in question, Dr. Lübbers, is an ENT specialist and, like all other German critics of homeopathy (apart from one, Dr. Grams), does not understand homeopathy.
  • There are thousands of physicians who do understand it and are fully trained in homeopathy.
  • They would therefore do a much better job in providing a lecture.
  • So, would the German internists please invite homeopaths for their future meetings?

And what is Riker trying to achieve?

  • It seems quite clear that he aims to prevent criticism of homeopathy.
  • He wishes to replace it with pro-homeopathy propaganda.
  • Essentially he wants to stifle free speech, it seems to me.

To reach these aims, he does not hesitate to embarrass himself by sending and making publicly available a very stupid letter. He also behaves in a most unprofessional fashion and does not mind putting a few untruths on paper.

Having said that, I will admit that they are in good company. Hahnemann was by all accounts a most intolerant and cantankerous chap himself. And during the last 200 years, his followers have given ample evidence that critical thinking has remained an alien concept for them. Consequently, such behavior seems not that unusual for German defenders of homeopathy. In recent times they have:

Quite a track record, wouldn’t you agree?

But, I think, attempting to suppress free speech beats it all and must be a new low in the history of homeopathy.

 

Absurd claims about spinal manipulative therapy (SMT) improving immune function have increased substantially during the COVID-19 pandemic. Is there any basis at all for such notions?

The objective of this systematic review was to identify, appraise, and synthesize the scientific literature on the efficacy and effectiveness of SMT in preventing the development of infectious disease or improving disease-specific outcomes in patients with infectious disease and to examine the association between SMT and selected immunological, endocrine, and other physiological biomarkers.

A literature search of MEDLINE, the Cumulative Index to Nursing and Allied Health Literature, the Index to Chiropractic Literature, the Cochrane Central Register of Controlled Trials, and Embase was conducted. Randomized clinical trials and cohort studies were included. Eligible studies were critically appraised, and evidence with high and acceptable quality was synthesized using the Synthesis Without Meta-Analysis guideline.

A total of 2593 records were retrieved; after exclusions, 50 full-text articles were screened, and 16 articles reporting the findings of 13 studies comprising 795 participants were critically appraised. No clinical studies were located that investigated the efficacy or effectiveness of SMT in preventing the development of infectious disease or improving disease-specific outcomes among patients with infectious disease. Eight articles reporting the results of 6 high- and acceptable-quality RCTs comprising 529 participants investigated the effect of SMT on biomarkers. Spinal manipulative therapy was not associated with changes in lymphocyte levels or physiological markers among patients with low back pain or participants who were asymptomatic compared with sham manipulation, a lecture series, and venipuncture control groups. Spinal manipulative therapy was associated with short-term changes in selected immunological biomarkers among asymptomatic participants compared with sham manipulation, a lecture series, and venipuncture control groups.

The authors concluded that no clinical evidence was found to support or refute claims that SMT was efficacious or effective in changing immune system outcomes. Although there were limited preliminary data from basic scientific studies suggesting that SMT may be associated with short-term changes in immunological and endocrine biomarkers, the clinical relevance of these findings is unknown. Given the lack of evidence that SMT is associated with the prevention of infectious diseases or improvements in immune function, further studies should be completed before claims of efficacy or effectiveness are made.

I fully agree with the data as summarised in this paper. Yet, I find the conclusions a bit odd. The authors of this paper are chiropractors who declare the following conflicts of interest: Dr Côté reported receiving grants from the College of Chiropractors of British Columbia during the conduct of the study and grants from the Canadian Chiropractic Research Foundation, travel expenses from the World Federation of Chiropractic, and personal fees from the Canadian Chiropractic Protective Association outside the submitted work. Dr Cancelliere reported receiving grants from the Canadian Chiropractic Research Foundation outside the submitted work. Dr Mior reported receiving grants from the College of Chiropractors of British Columbia during the conduct of the study and grants from the Canadian Chiropractic Association and the Ontario Chiropractic Association outside the submitted work. Dr Hogg-Johnson reported receiving grants from the College of Chiropractors of British Columbia during the conduct of the study and grants from the Canadian Chiropractic Research Foundation outside the submitted work. No other disclosures were reported. The research was supported by funding from the College of Chiropractors of British Columbia to Ontario Tech University, the Canada Research Chairs program (Dr Côté), and the Canadian Chiropractic Research Foundation (Dr Cancelliere).

Would authors independent of chiropractic influence have drawn the same conclusions? I doubt it! While I do appreciate that chiropractors published these negative findings prominently, I feel the conclusions could easily be put much clearer:

There is no clinical evidence to support claims that SMT is efficacious or effective in changing immune system outcomes. Further studies in this area are not warranted.

Low back pain must be one of the most frequent reasons for patients to seek out some so-called alternative medicine (SCAM). It would therefore be important that the information they get is sound. But is it?

The present study sought to assess the quality of web-based consumer health information available at the intersection of LBP and CAM. The investigators searched Google using six unique search terms across four English-speaking countries. Eligible websites contained consumer health information in the context of CAM for LBP. They used the DISCERN instrument, which consists of a standardized scoring system with a Likert scale from one to five across 16 questions, to conduct a quality assessment of websites.

Across 480 websites identified, 32 were deemed eligible and assessed using the DISCERN instrument. The mean overall rating across all websites 3.47 (SD = 0.70); Summed DISCERN scores across all websites ranged from 25.5-68.0, with a mean of 53.25 (SD = 10.41); the mean overall rating across all websites 3.47 (SD = 0.70). Most websites reported the benefits of numerous CAM treatment options and provided relevant information for the target audience clearly, but did not adequately report the risks or adverse side-effects adequately.

The authors concluded that despite some high-quality resources identified, our findings highlight the varying quality of consumer health information available online at the intersection of LBP and CAM. Healthcare providers should be involved in the guidance of patients’ online information-seeking.

In the past, I have conducted several similar surveys, for instance, this one:

Background: Low back pain (LBP) is expected to globally affect up to 80% of individuals at some point during their lifetime. While conventional LBP therapies are effective, they may result in adverse side-effects. It is thus common for patients to seek information about complementary and alternative medicine (CAM) online to either supplement or even replace their conventional LBP care. The present study sought to assess the quality of web-based consumer health information available at the intersection of LBP and CAM.

Methods: We searched Google using six unique search terms across four English-speaking countries. Eligible websites contained consumer health information in the context of CAM for LBP. We used the DISCERN instrument, which consists of a standardized scoring system with a Likert scale from one to five across 16 questions, to conduct a quality assessment of websites.

Results: Across 480 websites identified, 32 were deemed eligible and assessed using the DISCERN instrument. The mean overall rating across all websites 3.47 (SD = 0.70); Summed DISCERN scores across all websites ranged from 25.5-68.0, with a mean of 53.25 (SD = 10.41); the mean overall rating across all websites 3.47 (SD = 0.70). Most websites reported the benefits of numerous CAM treatment options and provided relevant information for the target audience clearly, but did not adequately report the risks or adverse side-effects adequately.

Conclusion: Despite some high-quality resources identified, our findings highlight the varying quality of consumer health information available online at the intersection of LBP and CAM. Healthcare providers should be involved in the guidance of patients’ online information-seeking.

Or this one:

Background: Some chiropractors and their associations claim that chiropractic is effective for conditions that lack sound supporting evidence or scientific rationale. This study therefore sought to determine the frequency of World Wide Web claims of chiropractors and their associations to treat, asthma, headache/migraine, infant colic, colic, ear infection/earache/otitis media, neck pain, whiplash (not supported by sound evidence), and lower back pain (supported by some evidence).

Methods: A review of 200 chiropractor websites and 9 chiropractic associations’ World Wide Web claims in Australia, Canada, New Zealand, the United Kingdom, and the United States was conducted between 1 October 2008 and 26 November 2008. The outcome measure was claims (either direct or indirect) regarding the eight reviewed conditions, made in the context of chiropractic treatment.

Results: We found evidence that 190 (95%) chiropractor websites made unsubstantiated claims regarding at least one of the conditions. When colic and infant colic data were collapsed into one heading, there was evidence that 76 (38%) chiropractor websites made unsubstantiated claims about all the conditions not supported by sound evidence. Fifty-six (28%) websites and 4 of the 9 (44%) associations made claims about lower back pain, whereas 179 (90%) websites and all 9 associations made unsubstantiated claims about headache/migraine. Unsubstantiated claims were made about asthma, ear infection/earache/otitis media, neck pain,

Conclusions: The majority of chiropractors and their associations in the English-speaking world seem to make therapeutic claims that are not supported by sound evidence, whilst only 28% of chiropractor websites promote lower back pain, which is supported by some evidence. We suggest the ubiquity of the unsubstantiated claims constitutes an ethical and public health issue.

The findings were invariably disappointing and confirmed those of the above paper. As it is nearly impossible to do much about this lamentable situation, I can only think of two strategies for creating progress:

  1. Advise patients not to rely on Internet information about SCAM.
  2. Provide reliable information for the public.

Both describe the raison d’etre of my blog pretty well.

Recently, I came across a newspaper asking: “Which vaccine do you trust most?” It turned out that there was a clear favourite according to public opinion. In the present climate of heated debates about COVID vaccines, this seems to make sense.

Or doesn’t it?

What determines public opinion?

There are probably many determinants, but most are dominated by what the public is being told about a subject. If, for instance, the press incessantly reports bad things about a certain vaccine and mostly good news about another, public opinion will reflect exactly that.

What I am trying to point out is this: the man and woman in the street have no expertise in vaccines. They mostly think what they are being told about them. So, public opinion is largely determined by journalists who write about the subject. If then a newspaper presents the public opinion about a vaccine, it is all but a foregone conclusion. The paper might as well just repeat what they have been telling their readers. By presenting a ‘public opinion’ about vaccines they actually go one step further: they amplify their own opinion by pretending it is not of their making but that of the public.

All this seems fairly obvious, once you start thinking about it.

So, why do I go on about it?

If this phenomenon occurs with vaccines, it also occurs with other issues, for instance, so-called alternative medicine (SCAM). We often hear that the public is in favour of this or that type of SCAM. It is supposed to convince us and politicians that SCAM is good. If thousands or even millions are in favour of it, it must be good! Who am I to disagree with the public?

But, as we have just seen with the example of the vaccines, public opinion is merely a reflection of what the press tells people. The man and the woman in the street are not competent to reliably estimate the risk-benefit ratios of St John’s wort, Arnica, glucosamine, acupuncture, etc. etc. They can judge such issues as little as they can judge the risk-benefit balance of a vaccine. They rely on information from the outside, and that information usually reaches them by the press.

What am I aiming at?

Public opinion sounds impressive, and in the realm of SCAM, it often determines much. If the public opinion is in favour of homoeopathy, for instance, politicians are likely to lend their support to it. Yet, public opinion is just OPINION! It cannot be used as an indicator for the efficacy or safety of medical interventions, and it cannot be the reason for using or rejecting them.

It follows, I think, that journalists have a huge responsibility to inform the public correctly on SCAM (and any other matter). On this blog, we have seen numerous instances of journalists who could have done better, e.g.:

Public opinion, it seems to me, can only be meaningful, if the information fed to the public is sound. And when it comes to SCAM, this condition is often not met.

 

 

Previous studies have shown inconclusive results of homeopathy in the treatment of warts. A team of Indian homeopaths aimed to assess the feasibility of a future definitive trial, with a preliminary assessment of differences between effects of individualized homeopathic (IH) medicines and placebos in the treatment of cutaneous warts.

A double-blind, randomized, placebo-controlled trial (n = 60) was conducted at the dermatology outpatient department of D.N. De Homoeopathic Medical College and Hospital, West Bengal. Patients were randomized to receive either IH (n = 30) or identical-looking placebo (n = 30). Primary outcome measures were numbers and sizes of warts; the secondary outcome was the Dermatology Life Quality Index (DLQI) questionnaire measured at baseline, and every month up to 3 months. Group differences and effect sizes were calculated on the intention-to-treat sample.

Attrition rate was 11.6% (IH, 3; placebo, 4). Intra-group changes were significantly greater (all < 0.05, Friedman tests) in IH than placebo. Inter-group differences were statistically non-significant (all > 0.05, Mann-Whitney U tests) with small effect sizes-both in the primary outcomes (number of warts after 3 months: IH median [inter-quartile range; IQR] 1 [1, 3] vs. placebo 1 [1, 2]; p = 0.741; size of warts after 3 months: IH 5.6 mm [2.6, 40.2] vs. placebo 6.3 [0.8, 16.7]; p = 0.515) and in the secondary outcomes (DLQI total after 3 months: IH 4.5 [2, 6.2] vs. placebo 4.5 [2.5, 8]; p = 0.935). Thuja occidentalis (28.3%), Natrum muriaticum (10%) and Sulphur (8.3%) were the most frequently prescribed medicines. No harms, homeopathic aggravations, or serious adverse events were reported.

The Indian homeopaths draw the following conclusion: As regards efficacy, the preliminary study was inconclusive, with a statistically non-significant direction of effect favoring homeopathy. The trial succeeded in showing that an adequately powered definitive trial is both feasible and warranted.

INCONCLUSIVE?

No, the findings are not inconclusive at all! Read the results again: they confirm that homeopathy is a placebo therapy.

So, why is this trial worth writing about?

Surely, we did not expect anything else than a negative outcome from such a study?!

No, we didn’t.

But there is still something quite remarkable about this study: I have previously noted that virtually all studies of homeopathy by Indian researchers report positive results. AND THIS ONE DOESN’T!!!

Alright, it tries to hide the fact that the findings were negative, but this already seems to be a step in the right direction. So, well done, my Indian friends!!!

Perhaps one day, you will be able to admit that homeopathy is a placebo therapy?

 

 

The General Chiropractic Council’s (GCC) Registrant Survey 2020 was conducted in September and October 2020. Its aim was to gain valuable insights into the chiropractic profession to improve the GCC’s understanding of chiropractic professionals’ work and settings, qualifications, job satisfaction, responsibilities, clinical practice, future plans, the impact of the COVID-19 pandemic on practice, and optimism and pessimism about the future of the profession.

The survey involved a census of chiropractors registered with the GCC. It was administered online, with an invitation email was sent to every GCC registrant, followed by three reminders for those that had not responded to the survey. An open-access online survey was also available for registrants to complete if they did not respond to the mailings. This was promoted using the GCC website and social media channels. In total, 3,384 GCC registrants were eligible to take part in the survey. A fairly miserable response rate of 28.6% was achieved.

Here are 6 results that I found noteworthy:

  • Registrants who worked in clinical practice were asked if performance was monitored at any of the clinical practices they worked at. Just over half (55%) said that it was and a third (33%) said it was not. A further 6% said they did not know and 6% preferred not to say. Of those who had their performance monitored, only 37% said that audits of clinical care were conducted.
  • Registrants working in clinical practice were asked if any of their workplaces used a patient safety incident reporting system. Just under six in ten (58%) said at least one of them did, whilst 23% said none of their workplaces did. A further 12% did not know and 7% preferred not to say.
  • Of the 13% who said they had a membership of a Specialist Faculty, a third (33%) said it was in paediatric chiropractic, 25% in sports chiropractic, and 16% in animal chiropractic. A further 13% said it was in pain and the same proportion (13%) in orthopaedics.
  • Registrants who did not work in chiropractic research were asked if they intended to work in that setting in the next three years. Seven in ten (70%) said they did not intend to work in chiropractic research in the next three years, whilst 25% did not know or were undecided. Only 5% said they did intend to work in chiropractic research.
  • Registrants were also asked how easy it is to keep up to date with recommendations and advances in clinical practice. Overall, two-thirds (67%) felt it was easy and 30% felt it was not.
  • Registrants were asked in the survey whether they felt optimistic or pessimistic about the future of the profession over the next three years. Overall, half (50%) said they were optimistic and 23% were pessimistic. A further 27% said they were neither optimistic nor pessimistic.

Perhaps even more noteworthy are those survey questions and subject areas that might have provided interesting information but were not included in the survey. Here are some questions that spring into my mind:

  • Do you believe in the concept of subluxation?
  • Do you treat conditions other than spinal problems?
  • How frequently do you use spinal manipulations?
  • How often do you see adverse effects of spinal manipulation?
  • Do you obtain informed consent from all patients?
  • How often do you refer patients to medical doctors?
  • Do you advise in favour of vaccinations?
  • Do you follow the rules of evidence-based medicine?
  • Do you offer advice about prescribed medications?
  • Which supplements do you recommend?
  • Do you recommend maintenance treatment?

I wonder why they were not included.

 

Osteopathic manipulative treatment (OMT) is frequently recommended by osteopaths for improving breastfeeding. But does it work?

This double-blind randomised clinical trial tested whether OMT was effective for facilitating breastfeeding. Breastfed term infants were eligible if one of the following criteria was met:

  • suboptimal breastfeeding behaviour,
  • maternal cracked nipples,
  • maternal pain.

The infants were randomly assigned to the intervention or the control group. The intervention consisted of two sessions of early OMT, while in the control group, the manipulations were performed on a doll behind a screen. The primary outcome was the exclusive breastfeeding rate at 1 month, which was assessed in an intention-to-treat analysis. Randomisation was computer generated and only accessible to the osteopath practitioner. The parents, research assistants and paediatricians were masked to group assignment.

One hundred twenty-eight mother-infant dyads were randomised, with 64 assigned to each group. In each group, five infants were lost to follow-up. In the intervention group, 31 of 59 (53%) of infants were still exclusively breastfed at 1 month vs 39 of 59 (66%) in the control group. After adjustment for suboptimal breastfeeding behaviour, caesarean section, use of supplements and breast shields, the adjusted OR was 0.44. No adverse effects were reported in either group.

The authors concluded dryly that OMT did not improve exclusive breastfeeding at 1 month.

This is a rigorous trial with clear and expected results. It was conducted in cooperation with a group of 7 French osteopaths, and the study was sponsored by the ‘Société Européenne de Recherche en Osthéopathie Périnatale et Pédiatrique’, the ‘Fonds pour la Recherche en Ostéopathie’ and ‘Formation et Recherche Ostéopathie et Prévention’. The researchers need to be congratulated on publishing this trial and expressing the results so clearly despite the fact that the findings were not what the osteopaths had hoped for.

Three questions come to my mind:

  1. Is any of the many therapeutic recommendations of osteopaths valid?
  2. Why was it ever assumed that OMT would be effective?
  3. Do we really have to test every weird assumption before we can dismiss it?

In the world of homeopathy, Prof Michael Frass is a famous man. He is the First Chairman of the Scientific Society for Homeopathy (WissHom), the president of the Umbrella organization of Austrian Doctors for Holistic Medicine, and the Vicepresident of the Doctors Association for Classical Homeopathy. Frass has featured on this blog before, not least because he has published numerous studies of homeopathy, none of which has ever failed to produce a positive result

This is not just remarkable, in my view, it defies logic and the laws of nature. Even if homeopathy were a supremely effective therapy – a very broad consensus holds that it is not! – one would occasionally expect some negative results. No treatment works under all circumstances

… that is no treatment except homeopathy, according to Frass.

Recently Frass amazed even the world of oncology by publishing a study suggesting that homeopathy can prolong the survival of lung cancer patients. Every oncologist I know was flabbergasted.

Can this be true? This is the question, many people have been asking for some time in relation to Frass’s research.

In my quest to shine more light on it, I was recently alerted to an article by the formidable Austrian investigative journalist, Alwin Schönberger. In 2015, he came across a press release announcing that “HOMEOPATHY HAD BEEN PROVEN TO WORK AFTER ALL” (strikingly similar to one issued in 2018). It came from Austria’s leading manufacturer who was giving an award to an apparently outstanding thesis supervised by Frass. Even today, this piece of research has not been published in the peer-reviewed literature.

Yet, after some difficulties, Schönberger managed to obtain a copy. What he found was surprising, and he thus published his findings in the respected Austrian journal ‘Profil’ (2. Mai 2015 • profil 22).

Frass’s student had been given the task to systematically review all the homeopathy trials published between 2008 and 2012. Contrary to the hype of the press release, the meta-analysis merely suggested a very small effect. When digging deeper, Schönberger found several inconsistencies and mistakes in the analysis. They all were such that they produced a false-positive picture for homeopathy. Upon their correction, homeopathy turned out to be no longer significantly superior to placebo. Frass was then interviewed about it and claimed that the inconsistencies were only ‘errors’ but insisted that homeopathy is not a placebo therapy.

Yes, of course, errors happen in research. But if they all go in one direction and if that direction coincides with the interests of the researchers, we have the right, perhaps even the duty, to be suspicious. The questions that arise from this story are, I think, as follows:

  • Have the errors been corrected?
  • Are there perhaps other errors in Frass’s research?
  • Can we trust anything that Frass says?
  • Is it time to consider an official investigation into Frass’s studies of homeopathy?

 

 

Just when I thought I had received all the insults that one can possibly invent – including that I falsified my qualifications (!) – there comes a new one that nobody has ever thought of.

Like all my books, the new one (this one is in German) is dividing opinions sharply. That has to be expected in the realm of so-called alternative medicine, I suppose. Even though I had hoped to avoid such divisions by discussing the 20 best and the 20 most concerning modalities, there seems to be very little middle ground.

We already discussed the review of our regular Heinrich Huemmer. It was withdrawn by Amazon presumably because it was too offensive and later replaced by his second attempt. Now we have a new review which arguably is even more insulting:

Edzard Ernst ist ein verbitterter, älterer Ex-Wissenschaftler, der in seiner nachuniversitären Ruhestandszeit die Privatfehde mit seinem Erzfeind Prince Charles, wie im Film “Und täglich grüsst das Murmeltier” wieder und wieder aufarbeiten muss. Das letzte traurige Ergebnis gibt’s jetzt hier.

Here is the translation:

Edzard Ernst is an embittered, elderly ex-scientist who, in his post-university retirement, has to rehash the private feud with his nemesis Prince Charles over and over again, as in the movie “And Every Day the Groundhog Greets.” The latest sad result is now available here.

The review was posted on 21/3/2021 by an anonymous person who had not bought or read the book. As it might also be withdrawn by Amazon for being offensive, I thought I better keep it here for posterity. I find it quite nice because it shows the lack of reason that shines through so often when my critics try to form a coherent argument.

So, please allow me to do a quick analysis:

  • I cannot very well judge whether I am embittered. Those around me would deny it, however.
  • Yes, I suppose I am elderly; the same age as Charles, actually. If ‘elderly’ is used in a derogatory sense, it gets rather unpleasant, if you ask me.
  • I am not an ex-scientist. I still do quite a bit of science which, by any standards, makes me a scientist.
  • I don’t think I have a ‘private feud’ with Charles. A feud is an argument that has existed for a long time between two people or groups, causing a lot of anger or violence. If anything I am a critic of Charles’ actions related to SCAM. He has never argued back which means that this does not amount to a feud. If it were a feud, it would also not be private. I have always made my criticism public.
  • Is Charles my nemesis? Someone’s nemesis is a person or thing that is very difficult for them to defeat. Charles would indeed be very difficult to defeat because he never discusses with people who are not of his opinion. So, perhaps this point is correct? Yes, except, I never expected to ‘defeat’ Charles; I would be entirely happy to make him realise that some of his notions are ill-conceived.
  • Do I really have to rehash whatever it is over and over again? I fear that here the book reviewer is mistaken. Charles is one of the world’s most influential proponents of so-called alternative medicine (SCAM). I am one of the leading experts in this field. Therefore it is only to be expected that I regularly come across his activities.
  • “The latest sad result is now available here.” This implies that my new book is full of mentions of Charles. The truth is that Charles or his activities are not mentioned even once (at least I did not find anything when checking just mow).

Boring trivialities?

Not really!

I do find the book review quite revealing. It shows that there must be some (I fear many) people out there who are not willing to even consider an argument deemed to be contrary to their conviction. They close their eyes and ears in motivated ignorance. The funny thing is that this happens even in relation to a book in which I really did try to show some positive sides of SCAM.

In other words, even when I evidently write about the positive aspects of SCAM, the opposition remains stubbornly, closed-minded, and accuses me of closed-mindedness.

Not without irony, that!

There are plenty of people who find it hard to accept that highly diluted homeopathic remedies are placebos. They religiously believe in the notion that homeopathy works and studiously ignore the overwhelming evidence (plus a few laws of nature). Yet, they pretend to staunchly believe in science and keep on conducting (pseudo?) scientific studies of homeopathy. To me, this seems oddly schizophrenic because, on the one hand, they seem to accept science by conducting trials, while, on the other hand, they reject science by negating the scientific consensus.

The objective of this recent study was to evaluate the quality of life (QoL) of women treated with homeopathy within the Public Health System of Belo Horizonte, Brazil.

The study was designed as a prospective randomized controlled pragmatic trial. The patients were divided into two independent groups, one group underwent homeopathic treatment during a 6-month period, while the other did not receive any homeopathic treatment. In both randomized groups, patients maintained their conventional medical treatment as necessary. The World Health Organization Quality of Life abbreviated questionnaire (WHOQOL-BREF) was used for QoL analysis prior to treatment and 6 months later.

Randomization was successful in that it resulted in similar baseline results in three domains of QoL analysis for both groups. After 6 months’ treatment, the investigators noted a statistically significant difference between groups in the physical domain of WHOQOL-BREF: the average score improved to 63.6 ± (SD) 15.8 in the homeopathy group, compared with 53.1 ± (SD) 16.7 in the control group.

The authors concluded that homeopathic treatment showed a positive impact at 6 months on the QoL of women with chronic diseases. Further studies should be performed to determine the long-term effects of homeopathic treatment on QoL and its determinant factors.

I would not be surprised if the world of homeopathy were to celebrate this trial as yet another proof that homeopathy is effective. I am afraid, however, that I might have to put a damper on their excitement:

THIS STUDY DOES NOT SHOW WHAT YOU THINK IT DOES.

Why not?

Regular readers of this blog will have already guessed it: the trail follows the infamous ‘A+B versus B’ design. Some people will think that I am obsessed with this theme – but I am not; it’s just that, in SCAM, it comes up with such depressing regularity. And as this blog is mainly about commenting on newly published research, I am unable to avoid the subject.

So, let me explain it again.

Think of it in monetary terms: you have an amount X, your friend has the same amount X plus an extra sum Y. Who do you think has more money? You don’t need to be a genius to guess, do you?

The same happens in the above ‘A+B versus B’ trial:

  • the patients in group 1 received homeopathy (A) plus usual care (B);
  • the patients in group 2 received usual care (B) and nothing else.

You don’t need to be a genius to guess who might have the better outcomes.

Because of homeopathy?

No! Because of the patients’ expectation, the placebo effect, and the extra attention of the homeopaths. They call this trial design ‘pragmatic’. I feel it is an attempt to mislead the public.

So, allow me to re-write the authors’ conclusion as follows:

The effect of a homeopathic consultation and the administration of a placebo generated a positive impact at 6 months on the QoL of women with chronic diseases. This was entirely predictable and totally unrelated to homeopathy. Further studies to determine the long-term effects of homeopathic treatment on QoL and its determinant factors are not needed.
