case report

1 2 3 8

Doctor Jens Wurster is no stranger to this blog; previously I discussed his claim that he has treated more than 1000 cancer patients homeopathically and we could even cure or considerably ameliorate the quality of life for several years in some, advanced and metastasizing cases. So far, his claims were based not on evidence published in peer-reviewed journals (I cannot find a single Medline-listed paper by this man); but now Wurster has published an article in a German Journal (Wurster J. Zusatznutzen der Homöopathie … Deutsche Zeitschrift für Onkologie 2018; 50: 85–91; not Medline-listed, I am afraid). The paper is in German, but it has an English abstract; here it is:

____________________________________________________________________________

All over the world, oncology patients receive homeopathic treatment concomitant to conventional treatments, such as chemotherapy and radiation treatment, in order to reduce the side effects of these therapies. It has been shown that cancer patients, who are receiving homeopathic treatment in addition to conventional therapies, have a higher quality of life and a longer survival rate. Studies in cancer cell research have shown the direct effects of highly potentized homeopathic medicines on tumor cell lines. Tumor inhibiting properties of homeopathic medicines have been proven in vivo as well as in vitro. Research projects into complementary medicine (CAMbrella) and research into personalized immunotherapies as well as additive homeopathy open the door to the future of integrative oncology.

_____________________________________________________________________________

In the article, Wurster states that he has 20 years of experience in treating cancer with homeopathy as an add-on to conventional care, and that he can confirm homeopathy’s effectiveness. He claims that ‘very many’ patients have thus benefitted by experiencing less side-effects of conventional treatments. And he offers two case-reports to illustrate this.

[Nach 20 Jahren klinischer Erfahrung in der Clinica St. Croce im Tessin mit der Behandlung onkologischer Patienten mithilfe der Homöopathie können wir deutlich den Zusatznutzen der Homöopathie in der Onkologie bestätigen [1]. So gelang es unserem Ärzteteam in den zurückliegenden Jahren bei sehr vielen Patienten, durch gezielten Einsatz homöopathischer Mittel die Nebenwirkungen von Chemotherapien oder Bestrahlungen erfolgreich zu reduzieren [1]. Wie dabei Schulmedizin und Homöopathie in der Praxis zusammenwirken, zeigt folgendes Beispiel. ([1] Wurster J. Die homöopathische Behandlung und Heilung von Krebs und metastasierten Tumoren. Norderstedt: Books on Demand; 2015)]

The two case-reports lack detail and are less than convincing, in my view. Both patients have had conventional therapies and Wurster claims that his homeopathic remedies reduced their side-effects. There is no way of verifying this claim, and the improvements might have occurred also without homeopathy.

In the discussion section of his paper, Wurster then elaborates that oncologists throughout Europe are now realising the potential of homeopathy. In support he mentions paediatric oncologists in Klagenfurt who managed to spare pain-killers by giving homeopathics. Similarly, at the Inselspital in Bern, they are offering homeopathic consultations to complement conventional treatments.

[Inzwischen haben auch einige Onkologen erkannt, wie eine gezielt eingesetzte homöopathische Behandlung die Nebenwirkungen von Chemotherapien oder Bestrahlungen reduzieren kann. Wir arbeiten inzwischen mit einigen Onkologen aus ganz Europa zusammen, die den Zusatznutzen der Homöopathie in der Onkologie erlebt haben. In der Kinderonkologie in Klagenfurt beispielsweise konnten mithilfe der Homöopathie Schmerzmittel bei den Kindern eingespart werden. Auch am Inselspital Bern werden zusätzliche homöopathische Konsile in der Kinderonkologie angeboten, um die konventionelle Behandlung begleiten zu können [8].]

At this point, Wurster inserts his reference number 8. As several of his references are either books or websites, this reference to an article in a top journal seems interesting. Here is its abstract:

___________________________________________________________________________________

BACKGROUND:

Though complementary and alternative medicine (CAM) are frequently used by children and adolescents with cancer, there is little information on how and why they use it. This study examined prevalence and methods of CAM, the therapists who applied it, reasons for and against using CAM and its perceived effectiveness. Parent-perceived communication was also evaluated. Parents were asked if medical staff provided information on CAM to patients, if parents reported use of CAM to physicians, and what attitude they thought physicians had toward CAM.

STUDY DESIGN:

All childhood cancer patients treated at the University Children‘s Hospital Bern between 2002-2011 were retrospectively surveyed about their use of CAM.

RESULTS:

Data was collected from 133 patients (response rate: 52%). Of those, 53% had used CAM (mostly classical homeopathy) and 25% of patients received information about CAM from medical staff. Those diagnosed more recently were more likely to be informed about CAM options. The most frequent reason for choosing CAM was that parents thought it would improve the patient’s general condition. The most frequent reason for not using CAM was lack of information. Of those who used CAM, 87% perceived positive effects.

CONCLUSIONS:

Since many pediatric oncology patients use CAM, patients’ needs should be addressed by open communication between families, treating oncologists and CAM therapists, which will allow parents to make informed and safe choices about using CAM.

_______________________________________________________________________________________

Any hope that this paper might back up the statements made by Wurster is thus disappointed.

Altogether, this Wurster-paper contains no reliable evidence. The only clinical trial it seems to rely on is the one by Prof Frass which we have discussed previously here and here. The Frass-study is odd in several ways and, before we can take its results seriously, we need to see an independent replication of its findings. In this context, it is noteworthy that my own 2006 systematic review concluded that there is insufficient evidence to support clinical efficacy of homeopathic therapy in cancer care. In view of all this, I feel that the new Wurster-paper provides no reliable evidence and no reason to change my now somewhat dated conclusion of 2006. Moreover, I would insist that those who claim otherwise are unethical and behave irresponsible.

And finally, I need to reiterate what I stated in my previous post: the Wurster-paper indicates that something is amiss with medical publishing. How can it be that, in 2018, the ‘Deutsche Zeitschrift für Onkologie’ (or any other medical journal for that matter) can be so bar of critical thinking to publish such dangerously misleading nonsense? The editors of this journal (Univ.-Prof. Dr. med. Arndt Büssing, Witten/Herdecke; Dr. med. Peter Holzhauer, Bad Trissl und München) and its editorial board members (L. Auerbach, Wien; C. Bahne Bahnson, Kiel; J. Büntzel, Nordhausen; B. Freimüller-Kreutzer, Heidelberg; H.R. Maurer, Berlin; A. Mayr, Starnberg; R. Moss, New York; T. Ostermann, Witten/Herdecke; K. Prasad, Denver; G. Pulverer, Köln; H. Renner, Nürnberg; C.P. Siegers, Lübeck; W. Schmidt, Greifswald; G. Uhlenbruck, Köln; B. Wolf, München; K.S. Zänker, Witten/Herdecke) should ask themselves whether they are taking their moral obligations seriously enough, or whether their behaviour is not a violation of their most fundamental ethical duties.

In our book ‘MORE HARM THAN GOOD‘ we allude to such problems as follows: …Spurious results are frequently paraded by CAM advocates in support of implausible treatments… the more poorly conceived and executed a research project is, the more likely it is to produce false-positive results. These results then may lead to repetitive cycles of unproductive work to explain what was found—often to simply disprove the erroneous results. This is an unfortunate feature of various fields of scientific research, but it has particularly serious implications in medical research. Moreover, researchers who practice and behave as advocates of CAM may unintentionally or deliberately distort or exaggerate weak findings. Invalid CAM research claims tend not to be put to rest; instead they are repeatedly recycled…

And:

The CAM practitioner who promotes untruths has either failed to enlighten themselves as to the facts—this being a central requirement of professional ethics— or has chosen to deliberately deceive patients. Either of these reasons for promulgating falsehoods amounts to a serious breach in terms of virtue ethics. According to almost all forms of ethical theory, the truth-violating nature of CAM renders it immoral in both theory and practice.

The damage that can result from such violations of medical ethics is not merely a matter for the ‘ivory towers of academia’, it can virtually be a matter of life and death.

In 2005, I published a systematic review of ophthalmic adverse effects after spinal manipulations. At the time, I found 14 case reports. Clinical symptoms and signs were diverse and included loss of vision, ophthalmoplegia, diplopia and Horner’s syndrome. The underlying mechanism was arterial wall dissection in most cases. The eventual outcome varied and often included permanent deficits. Causality was frequently deemed likely or certain.

I concluded that upper spinal manipulation is associated with ophthalmological adverse effects of unknown frequency. Ophthalmologists should be aware of its risks. Rigorous investigations must be conducted to establish reliable incidence figures.

Now a new article has emerged that throws more light on this issue:

A 46-year-old healthy male with a history of chronic musculoskeletal neck pain presented to the emergency department with left sided weakness after a syncopal episode. The patient had been treated with frequent chiropractic neck manipulations over the past seven years, with his last session one month prior to presentation. One week prior to presentation, the patient developed a new headache, anisocoria, and ptosis of his right upper eyelid. Computed tomography angiography (CTA) of the head and neck showed an internal carotid occlusion with right middle cerebral artery zone of ischemia, and tissue plasminogen activator (tPA) was administered. Subsequently, the patient experienced vision loss in his right eye. MRI and CTA were repeated, revealing a right ICA dissection from below the ophthalmic artery to the posterior communicating artery. On examination, vision in the right eye was no light perception (NLP) and the pupil was amaurotic. Fundus exam showed vascular attenuation, severe pallor of the optic nerve and retina, without a cherry red spot. A diagnosis of ophthalmic artery occlusion was made.

Inpatient workup revealed no stroke risk factors, and he was discharged on aspirin and clopidogrel therapy. Follow up imaging showed re-cannulation of the ICA, although vision remained NLP at outpatient evaluation the following month. Macular spectral domain optical coherence tomography (SDOCT) showed hyperreflectivity of the inner retina diffusely and of the outer retina and retinal pigment epithelium (RPE) centrally. Fluorescein angiography revealed patchy choroidal filling, delayed arterial filling, and macular nonperfusion. Three months after presentation, vision had improved to light perception, and remains stable at one year after the dissection.

Central retinal artery occlusion (CRAO) has been previously described after neck manipulation; however, these cases have been attributed to a dislodged embolic plaque rather than arterial dissection as in this case. Carotid artery dissection after neck manipulation is rare, although the exact incidence is unknown, and may be fatal.

The authors of this case report concluded that internal carotid artery dissection in this case was permanently devastating to the vision of a previously healthy young patient.

What follows is simple:

  1. upper spinal manipulations have no or very little proven benefit;
  2. they are associated with a finite risk;
  3. thus, their risk/benefit balance fails to be positive;
  4. consequently, upper spinal manipulations cannot be recommended as a treatment of any condition.

My previous post was about the question whether lay-homeopaths can practise homeopathy without breaking their code of ethics. The answer was NO, because they lack most of the skills needed to obtain informed consent.

What about doctor homeopaths?

Can they practice homeopathy ethically?

Doctors are, of course, also obliged to follow their ethical code, and that means they too must obtain informed consent from their patients before starting a therapy. This is, for instance, what the UK General Medical Council tells their members:

You must give patients the information they want or need about:

  1. the diagnosis and prognosis
  2. any uncertainties about the diagnosis or prognosis, including options for further investigations
  3. options for treating or managing the condition, including the option not to treat
  4. the purpose of any proposed investigation or treatment and what it will involve
  5. the potential benefits, risks and burdens, and the likelihood of success, for each option; this should include information, if available, about whether the benefits or risks are affected by which organisation or doctor is chosen to provide care
  6. whether a proposed investigation or treatment is part of a research programme or is an innovative treatment designed specifically for their benefit4 
  7. the people who will be mainly responsible for and involved in their care, what their roles are, and to what extent students may be involved
  8. their right to refuse to take part in teaching or research
  9. their right to seek a second opinion
  10. any bills they will have to pay
  11. any conflicts of interest that you, or your organisation, may have
  12. any treatments that you believe have greater potential benefit for the patient than those you or your organisation can offer.

You should explore these matters with patients, listen to their concerns, ask for and respect their views, and encourage them to ask questions.

You should check whether patients have understood the information they have been given, and whether or not they would like more information before making a decision. You must make it clear that they can change their mind about a decision.

Following the 8 points from my previous post (I am trying to apply the same criteria to both types of homeopaths), a medical homeopath might tell her patient (whose stomach pain turns out to be caused, let’s assume, by a stomach ulcer) roughly this:

  1. The tests show that you are suffering from stomach ulcer.
  2. The natural history of this condition is usually benign, but it needs effective treatment; if not, the problem would become serious.
  3. Conventional medicine has several effective therapeutic options.
  4. I nevertheless propose to treat you with a homeopathic remedy.
  5. There is no good evidence that it will work beyond a placebo effect.
  6. The remedy is harmless, but not giving you an effective treatment might cause considerable harm.
  7. The cost of the consultation is £80, and the remedy will cost you around £15.
  8. I suggest you come again in a week or two; perhaps we need quite a few consultations altogether.

Again, as with the lay-homeopath from my previous post, any sensible patient would walk away without accepting the treatment. This means that our doctor homeopath can only practice homeopathy, if she does not inform her patient about points 5 and 6. In other words, doctors who practice homeopathy cannot obtain adequately informed consent. We have recently seen a real case of this happening and ending in the death of the patient.

Of course, the homeopath might send her patient to a specialist; or she might decide to administer a conventional therapy herself. Either way, she would not be practising homeopathy.

The dilemma is real, yet it is rarely considered. Here is a short passage from our book where we discuss the ethics of alternative medicine in full detail:

Genuine informed consent is unattainable for most CAM modalities. This presents a serious and intractable ethical problem for CAM practitioners. Attempts to square this circle by watering down or redefining the criteria for informed consent are ethically indefensible. The concept of informed consent and its centrality in medical ethics therefore renders most CAM practice unacceptable. Conventional healthcare subscribes to the ethical principle ‘no consent, no treatment’; we are not aware of the existence of any good reasons to excuse CAM from this dictum.

As I said, the ethical practice of homeopathy is a practical impossibility.

Or do you think I got this wrong?

The Internet is full of complete nonsense about alternative medicine, as we all know. Much of it could be funny – if it was not so extremely dangerous. Misinformation on health can (and I am afraid does) kill people. One of the worst BS I have seen for a long time is this article entitled ‘Here’s What Oncologists Won’t Tell You About Essential Oils’.

A few excerpts might be of interest:

START OF QUOTES

…The human body resonates at a frequency of 62-78 MHz and scientists believe that diseases start at 58 MHz. Many studies have shown that negative thoughts can reduce our frequency by 12 MHz, while positive thinking raises it by 10.

This means that there are many things that can affect our health in ways we can’t imagine.

According to the latest studies, essential oils can fight cancer thanks to their antibacterial properties and their ability to change the frequency we resonate at.

One of the scientists involved in the study, Bruce Tainio, developed a special Calibrated Frequency Monitor that measures the frequency of essential oils and how they affect us. M. Suhail, an immunologist, says that cancer develops when the DNA in our cells’ nucleus is corrupted.

Essential oils can correct this and repair the code, effectively improving our chances against the terrible disease…

In his book “The Body Electric”, R. O. Becker said that our bodies’ electronic frequency determines our health.

Even Nikola Tesla said that removing outside frequencies can make us more resistant against ailments, while Dr. Otto Warburg discovered over a century ago that our cells have a specific electrical voltage that can drop due to a various factors and trigger diseases such as cancer.

However, science has now discovered that essential oils with higher frequencies can destroy diseases with lower frequencies.

Here’s a list of some of the oils used in the research and their electrical frequencies:

  • Juniper – 98 Mhz
  • Angelica – 85 Mhz
  • Frankincense – 147 MHz
  • Rose – 320 Mhz.
  • Sandalwood – 96 Mhz
  • Helichrysum – 181 MHz
  • Peppermint – 78 Mhz
  • Lavender – 118 Mhz

In the study, cinnamon, thyme, jasmine and chamomile oils had the best results when put up against breast cancer cells. Chamomile destroyed 93% of the cells in vitro, while thyme destroyed 97% of the cells…

11 oils were examined in total including bitter and sweet fennel, winter savory, peppermint, sage, lavender, chamomile and thyme.

Frankincense oil

According to Suhail, frankincense oil can divide the nucleus of cancer cells from the cytoplasm and prevent it from reproducing. The oil works thanks to the presence of the so-called monoterpenes which have the ability to kill cancer cells.

Frankincense oil works in all stages of cancer and is cytotoxic, meaning it doesn’t destroy healthy cells.

End-stage liver cancer patient

In the study, a patient with end-stage liver cancer was given only a few months left to live. The tumor was inoperable due to the large size, so having nothing to lose, the man decided to try frankincense oil.

He applied a bit under his tongue and topically on the area of the liver, and on his next doctor visit, the tumor has already reduced in size. The patient continued using frankincense oil, and it eventually reduced just enough to be operable. His tumor was later removed and the man is now happily enjoying his life free of cancer.

A child with brain cancer

One of the toughest cases among all the patients in the study was a little girl aged 5 with brain cancer. After exhausting all other options, the parents decided to give the girl a mixture of frankincense and sandalwood oil.

They rubbed the mixture on her feet while also rubbing a bit of lavender on her wrist. After a few months, the cancer was completely defeated!

Bladder cancer patient

Jackie Hogan is a woman suffering from bladder cancer who needed to undergo a surgery for bladder removal due to the cancer.

However, she decided to try using essential oils in her condition and after a few months of applying a mixture of sandalwood and frankincense oil topically on the area, she is cancer-free.

Stage-4 cancer patient

One woman in the research was diagnosed with stage-4 lung cancer which has already spread to other organs in her body.

Instead of agreeing to chemo and surgery, the woman started applying a bit of frankincense oil topically on the affected areas of her body every 2-3 hours and she was completely healthy in 7 months.

Breast cancer patient

A woman diagnosed with advanced breast cancer used a mixture of frankincense and lemongrass oil (topically and under the tongue) to defeat the disease in only a few months.

Cervical cancer patient

A woman with cervical cancer was given only a few months left to live, but thanks to the powers of frankincense oil, she managed to defeat the diseases in a couple of months.

There are many more patients who have managed to defeat different types of cancer using the remarkable powers of various essential oils…

____________________________________________________________________________

I do not think that these papers actually show what is claimed above. Specifically, none of the 4 articles refers to clinical effects of essential oil on cancer patients. In fact, according to a 2014 review, and a 2013 paper (the most recent summaries I found) there are no clinical trials of essential oil as a cure for cancer.

The conclusion therefore must be this: Essential oils might be an interesting area of research, yet one has to tell consumers and patients very clearly:

there is no evidence to suggest that using essential oils will change the natural history of any type of cancer. 

Few alternative fads have survived as long as the current Kombucha boom. Since decades, it is being hyped as the best thing since sliced bread. Consequently, it has become popular and is now being promoted as a veritable panacea, allegedly curing asthma, cataracts, diabetes, diarrhoea, gout, herpes, insomnia and rheumatism and purported to shrink the prostate and expand the libido, reverse grey hair, remove wrinkles, relieve haemorrhoids, lower hypertension, prevent cancer, and promote general well-being. Kambucha is believed to stimulate the immune system, and help with HIV infection. And – sure enough – it is ideal for detox!!!

One author goes even further and lists no less than 17 indications:

It’s good for your gut:

1. Kombucha contains naturally fermenting probiotics that help maintain healthy gut flora by increasing the number of beneficial organisms.
2. It preserves nutrients and breaks them down into an easily digestible form, which allows you to absorb them better.
3. It enhances the absorption of minerals, particularly calcium, iron, zinc, magnesium, phosphorous and copper.
4. Healthy gut flora improves digestion, fights candida overgrowth, improves mental clarity and stabilizes moods.
5. A healthy gut can also be attributed to reducing or eliminating depression an anxiety.
6. Kombucha contains numerous strains of yeasts and up to 20 different bacterial species (and possibly many more!).

It detoxifies the body:

7. The enzymes and bacterial acids in kombucha ease the burden on the liver by reducing pancreatic load.
8. Kombucha contains glucuronic acid, which binds to toxins and increases their excretion through the kidney or intestines.
9. In 1951, a popular Russian study found that the daily consumption of kombucha was correlated with an extremely high resistance to cancer.
10. It contains vitamin C, a potent detoxifier.

It supports the nervous system:

11. Kombucha contains vitamin B, which has been associated with reducing blood pressure and supporting the nervous system.

It’s anti-ageing and supports the joints:

12. Kombucha contains glucosamines, which are vital for the treatment and prevention of arthritis.
13. Kombucha allegedly eliminates grey hair, increases sex drive and improves eyesight.
14. Kombucha concentrates the antioxidants found in tea. Antioxidants not only fight the environmental toxins known as free radicals, which contribute to illness and disease, but help slow the aging process.
15. Theoretically, powerful antioxidant nutrients can prevent and lessen wrinkles by promoting skin elasticity.

It’s anti-microbial

16. Kombucha is anti-microbial due to it’s acetic and organic acids, proteins, enzymes and bacteriocins. It exerts anti-microbial activity against pathogenic bacteria like E coli and Salmonella. Incidentally, green tea kombucha has a high anti-microbial effect than when made with black tea.

It decreases sugar cravings

17. Emmet from Remedy told us that customers often comment that kombucha reduces their sugar cravings. “My take on this is that kombucha provides a natural energy boost and is therefore a handy antidote for when cravings kick in. It’s also a great way to break the soft drinks habit.”

END OF QUOTE

Sadly, none of these claims are based on anything that even vaguely resembles evidence. My own systematic review of 2003 aimed at locating and critically evaluating all human medical investigations of kombucha regardless of study design. However, no clinical studies were found relating to the efficacy of this remedy. Several case reports and case series raise doubts about the safety of kombucha. They include suspected liver damage, metabolic acidosis and cutaneous anthrax infections. One fatality was on record. I therefore concluded that on the basis of these data it was concluded that the largely undetermined benefits do not outweigh the documented risks of kombucha. It can therefore not be recommended for therapeutic use.

Since then no clinical trials have been published; but more information on the risks of Kombucha has emerged. A case report of a 54-year-old asthmatic woman, for instance. She presented to hospital with a 10-day history of breathlessness. On examination, she was tachypnoeic with mild wheeze. She had preserved peak flows and was saturating at 100% on room air. Investigations revealed severe metabolic lactic acidosis. On further questioning, it transpired that she drank kombucha tea, which has been linked to lactic acidosis. She made a full recovery with supportive management and cessation of the tea.

A case of hepatotoxicity has also been related to Kombucha consumption. Another case report tells the story of a 22 year old male, newly diagnosed with HIV, who became short of breath and febrile within twelve hours of Kombucha tea ingestion. He subsequently became combative and confused, requiring sedation and intubation for airway control. Laboratories revealed a lactate of 12.9 mmol/L, and serum creatinine of 2.1 mg/dL. The authors concluded that consumption of this tea should be discouraged, as it may be associated with life-threatening lactic acidosis.

But how can a simple tea like Kombucha cause such serious problems? The answer lies in the method of preparation which carries the risk of contamination: the Kombucha material is incubated at room temperature in a sugar-containing liquid for 7–12 days. It is hardly surprising that, under such conditions, human pathogens may grow. It follows that, depending on the method of preparation and standards of hygiene, some Kombucha teas may be entirely innocent whilst others carry the risk of contamination and infection. Contaminated batches may act like a ‘biological chain letter’.

Considering all this, here are my instructions for making Kombucha and enjoying it safely.

You will need:

  • 3 litres of filtered water
  • 10 green or black teabags
  • 1 SCOBY (symbiotic culture of bacteria and yeast)
  • ½ a cup of sugar

And this is what you need to do:

Boil the filtered water.

Pour over the teabags in a large container.

Add the sugar to the tea, and allow time to brew and cool (about two hours).

Pour the brewed tea into a large, jar and add the SCOBY.

Cover jar with cheesecloth, muslin or paper towel and secure with a rubber band.

Leave to brew for a week or more to taste.

Pour the kombucha into bottles

… and bin the lot.

I have often criticised papers published by chiropractors.

Not today!

This article is excellent and I therefore quote extensively from it.

The objective of this systematic review was to investigate, if there is any evidence that spinal manipulations/chiropractic care can be used in primary prevention (PP) and/or early secondary prevention in diseases other than musculoskeletal conditions. The authors conducted extensive literature searches to locate all studies in this area. Of the 13.099 titles scrutinized, 13 articles were included (8 clinical studies and 5 population studies). They dealt with various disorders of public health importance such as diastolic blood pressure, blood test immunological markers, and mortality. Only two clinical studies could be used for data synthesis. None showed any effect of spinal manipulation/chiropractic treatment.

The authors concluded that they found no evidence in the literature of an effect of chiropractic treatment in the scope of PP or early secondary prevention for disease in general. Chiropractors have to assume their role as evidence-based clinicians and the leaders of the profession must accept that it is harmful to the profession to imply a public health importance in relation to the prevention of such diseases through manipulative therapy/chiropractic treatment.

In addition to this courageous conclusion (the paper is authored by a chiropractor and published in a chiro journal), the authors make the following comments:

Beliefs that a spinal subluxation can cause a multitude of diseases and that its removal can prevent them is clearly at odds with present-day concepts, as the aetiology of most diseases today is considered to be multi-causal, rarely mono-causal. It therefore seems naïve when chiropractors attempt to control the combined effects of environmental, social, biological including genetic as well as noxious lifestyle factors through the simple treatment of the spine. In addition, there is presently no obvious emphasis on the spine and the peripheral nervous system as the governing organ in relation to most pathologies of the human body.

The ‘subluxation model’ can be summarized through several concepts, each with its obvious weakness. According to the first three, (i) disturbances in the spine (frequently called ‘subluxations’) exist and (ii) these can cause a multitude of diseases. (iii) These subluxations can be detected in a chiropractic examination, even before symptoms arise. However, to date, the subluxation has been elusive, as there is no proof for its existence. Statements that there is a causal link between subluxations and various diseases should therefore not be made. The fourth and fifth concepts deal with the treatment, namely (iv) that chiropractic adjustments can remove subluxations, (v) resulting in improved health status. However, even if there were an improvement of a condition following treatment, this does not mean that the underlying theory is correct. In other words, any improvement may or may not be caused by the treatment, and even if so, it does not automatically validate the underlying theory that subluxations cause disease…

Although at first look there appears to be a literature on this subject, it is apparent that most authors lack knowledge in research methodology. The two methodologically acceptable studies in our review were found in PubMed, whereas most of the others were identified in the non-indexed literature. We therefore conclude that it may not be worthwhile in the future to search extensively the non-indexed chiropractic literature for high quality research articles.

One misunderstanding requires some explanations; case reports are usually not considered suitable evidence for effect of treatment, even if the cases relate to patients who ‘recovered’ with treatment. The reasons for this are multiple, such as:

  • Individual cases, usually picked out on the basis of their uniqueness, do not reflect general patterns.
  • Individual successful cases, even if correctly interpreted must be validated in a ‘proper’ research design, which usually means that presumed effect must be tested in a properly powered and designed randomized controlled trial.
  • One or two successful cases may reflect a true but very unusual recovery, and such cases are more likely to be written up and published as clinicians do not take the time to marvel over and spend time on writing and publishing all the other unsuccessful treatment attempts.
  • Recovery may be co-incidental, caused by some other aspect in the patient’s life or it may simply reflect the natural course of the disease, such as natural remission or the regression towards the mean, which in human physiology means that low values tend to increase and high values decrease over time.
  • Cases are usually captured at the end because the results indicate success, meaning that the clinical file has to be reconstructed, because tests were used for clinical reasons and not for research reasons (i.e. recorded by the treating clinician during an ordinary clinical session) and therefore usually not objective and reproducible.
  • The presumed results of the treatment of the disease is communicated from the patient to the treating clinician and not to a third, neutral person and obviously this link is not blinded, so the clinician is both biased in favour of his own treatment and aware of which treatment was given, and so is the patient, which may result in overly positive reporting. The patient wants to please the sympathetic clinician and the clinician is proud of his own work and overestimates the results.
  • The long-term effects are usually not known.
  • Further, and most importantly, there is no control group, so it is impossible to compare the results to an untreated or otherwise treated person or group of persons.

Nevertheless, it is common to see case reports in some research journals and in communities with readers/practitioners without a firmly established research culture it is often considered a good thing to ‘start’ by publishing case reports.

Case reports are useful for other reasons, such as indicating the need for further clinical studies in a specific patient population, describing a clinical presentation or treatment approach, explaining particular procedures, discussing cases, and referring to the evidence behind a clinical process, but they should not be used to make people believe that there is an effect of treatment…

For groups of chiropractors, prevention of disease through chiropractic treatment makes perfect sense, yet the credible literature is void of evidence thereof. Still, the majority of chiropractors practising this way probably believe that there is plenty of evidence in the literature. Clearly, if the chiropractic profession wishes to maintain credibility, it is time seriously to face this issue. Presently, there seems to be no reason why political associations and educational institutions should recommend spinal care to prevent disease in general, unless relevant and acceptable research evidence can be produced to support such activities. In order to be allowed to continue this practice, proper and relevant research is therefore needed…

All chiropractors who want to update their knowledge or to have an evidence-based practice will search new information on the internet. If they are not trained to read the scientific literature, they might trust any article. In this situation, it is logical that the ‘believers’ will choose ‘attractive’ articles and trust the results, without checking the quality of the studies. It is therefore important to educate chiropractors to become relatively competent consumers of research, so they will not assume that every published article is a verity in itself…

END OF QUOTES

YES, YES YES!!!

I am so glad that some experts within the chiropractic community are now publishing statements like these.

This was long overdue.

How was it possible that so many chiropractors so far failed to become competent consumers of research?

Do they and their professional organisations not know that this is deeply unethical?

Actually, I fear they do and did so for a long time.

Why then did they not do anything about it ages ago?

I fear, the answer is as easy as it is disappointing:

If chiropractors systematically trained to become research-competent, the chiropractic profession would cease to exist; they would become a limited version of physiotherapists. There is simply not enough positive evidence to justify chiropractic. In other words, as chiropractic wants to survive, it has little choice other than remaining ignorant of the current best evidence.

I hear this argument so regularly that it might be worth analysing it (yet again) a bit closer.

It is used with the deepest of convictions by proponents of all sorts of quackery who point out that science does not know or explain everything – and certainly not their (very special) therapy. Science is just not sophisticated enough, they say; in fact, a few years ago, it could not even explain how Aspirin works. And just like Aspirin, their very special therapy – let’s call it energy healing (EH) for the sake of this post – does definitely and evidently work. There even is ample proof:

  • Patients get better after using EH, and surely patients don’t lie.
  • Patients pay for EH, and who would pay for something that does not work?
  • EH has survived hundreds of years, and ineffective therapies don’t.
  • EH practitioners have tons of experience and therefore know best.
  • They are respected by very important people and organisations.
  • EH is even reimbursed by some insurance companies.

You have all heard the argument, I’m sure.

How to respond?

The ‘proofs’ listed above are simply fallacies; as such they do not need more detailed discussions, I hope.

But how can we refute the notion that science is not yet sufficiently advanced to explain EH?

The simplest approach might be to explain that science has already tested EH and found it to be ineffective. There really is nothing more to say. And the often-quoted example of Aspirin does clearly not wash. True, a few decades ago, we did not know how it worked. But we always knew that it worked because we conducted clinical trials, and they generated positive results. These findings we the main reasons why scientists wanted to find out how it works, and eventually they did (and even got a Nobel Prize for it). Had the clinical trials not shown effectiveness, nobody would have been interested in alleged mechanisms of action.

With EH, things are different. Rigorous clinical trials of EH have been conducted, and the totality of this evidence fails to show that EH works. Therefore, chasing after a mechanism of action would be silly and wasteful. It’s true, science cannot explain EH, but this is not because it is not yet sophisticated enough; it is because there is nothing to explain. EH has been disproven, and waffling about ‘science is not yet able to explain it’ is either a deliberate lie or a serious delusion.

So far so good. But what if EH had not been submitted to clinical trials?

In such cases, the above line of argument would not work very well.

For instance, as far as I know, there is not a single rigorous clinical trial of crystal healing (CH). Does that mean that perhaps CH-proponents are correct when claiming that it does evidently work and science simply cannot yet understand how?

No, I don’t think so.

Like most of the untested alternative therapies, CH is not based on plausible assumptions. In fact, the implausibility of the underlying assumptions is the reason why such treatments have not and probably never will be submitted to rigorous clinical trials. Why should anyone waste his time and our money running expensive tests on something that is so extremely unlikely? Arguably doing so would even be unethical.

With highly implausible therapies we need no trials, and we do not need to fear that science is not yet sufficiently advance to explain them. In fact, science is sufficiently advanced to be certain that there can be no explanation that is in line with the known laws of nature.

Sadly, some truly deluded fans of CH might still not be satisfied and respond to our reasoning that we need a ‘paradigm shift’. They might say that science cannot explain CH because it is stuck in the straightjacket of an obsolete paradigm which does not cater for phenomena like CH.

Yet this last and desperate attempt of the fanatics is not a logical refuge. Paradigm shifts are not required because some quack thinks so, they are needed only if data have been emerging that cannot possibly be explained within the current paradigm. But this is never the case in alternative medicine. We can explain all the experience of advocates, positive results of researchers and ‘miracle’ cures of patients that are being reported. We know that the experiences are real, but are sure that their explanations of the experience are false. They are not due to the treatment per se but to other phenomena such as placebo effects, natural history, regression towards the mean, spontaneous recovery, etc.

So, whichever way we turn things, and whichever way enthusiasts of alternative therapies twist them, their argument that ‘SCIENCE IS NOT YET ABLE TO EXPLAIN’ is simply wrong.

Today, enthusiasts of homeopathy celebrate the start of the HOMEOPATHY AWARENESS WEEK. Let’s join them by re-addressing one of their favourite themes: their personal experience with homeopathy.

Most homeopathy-fans argue that the negative scientific evidence must be wrong because they have had positive experiences. Whenever I give a lecture, for instance, there will be at least one person in the audience who presents such an experience (and I too could contribute a few such stories from my own past). Such ‘case reports’ can, of course, be interesting, illuminating or leading to further research, but they can never be conclusive.

This concept is often profoundly confusing for patients and consumers. They tend to feel that I am doubting their words, but nothing could be further from the truth. Their experience is certainly true – what might be false is their interpretation of it. I think, I better explain this in more detail using a concrete, published example.

After the publication of our 2003 RCT of homeopathic Arnica which showed that two different potencies have effects that do not differ from those of placebo, I received lots of angry responses from people who told me that they had the opposite experience or observed positive outcomes on their pets. In my subsequent publication in the journal ‘Homeopathy‘ entitled ‘The benefits of Arnica: 16 case reports‘, I have tried my best to explain their experiences in the light of our finding that highly diluted homeopathic Arnica is a placebo:

Sixteen case reports of the apparent benefits of Arnica … raise several relevant points. Firstly, topical Arnica preparations are often wrongly equated with homeopathic Arnica, the subject of our trial. The former are herbal preparations (ie not homeopathically diluted), which have undisputed pharmacological activity. Taken orally they would even be toxic. Thus all Arnica for oral administration must be highly diluted and has therefore no pharmacological effects. The case reports show that many lay people seem to be unclear about the difference between herbal and homeopathic Arnica.

Secondly, if animals seem to respond to homeopathic Arnica, as claimed in several of the case reports, this is not necessarily a proof of its effectiveness. Animals are not immune to placebo effects. Think of Pavlov’s experiments and the fact that conditioning is clearly an element in the placebo response.

Thirdly, the natural history of the condition can mimic clinical improvement caused by therapy. Many of the 16 cases summarized can be explained through a placebo response or the natural history of disease or the combination of both phenomena…

Many of the letters I received were outspoken to say the least. The authors stated that they were ‘appalled’, ‘saddened and angry’ by our research. Others implied that I was paid by the pharmaceutical industry to abolish homeopathy in the UK. One person felt that ‘it is highly irresponsible to dismiss a natural healing remedy with no evidence at all’. I believe the case reports … convey an important message about the power of belief, anecdotes, placebos and expectation.

The thing about case reports and personal experiences is quite simply this: they may seem almost overwhelmingly convincing, but they can NEVER serve as a proof that the treatment in question was effective. The reason for this fact could not be more simple. Any therapeutic response is due to a complex combination of factors: placebo effects, natural history of the condition, regression to the mean, etc.

See it this way: you wake up one morning with an enormous hangover. You try to identify the cause of it. Was it the beer you had in the pub? The wine you drank before you went out? Or the whiskey you consumed before you went to bed? Perhaps you think it was the Cognac you enjoyed at a friend’s house? Only one thing is for sure: it was not the glass of shaken water you drank during the night.

 

Dr. Dietmar Payrhuber is not famous – no, by no means. I had never heard of him until a watched this TV discussion about homeopathy (it’s in German, and well-worth watching, if you understand the language). I found the discussion totally mesmerising: Payrhuber is allowed to come out with case after case alleging he cured cancer of various types with homeopathy. Prof Frass is also there to defend the indefensible, but hardly intervenes, other than repeatedly and pompously stating that he is a professor with 200 publications who runs a homeopathy clinic at the university hospital of Vienna and therefore he is a cut above.

There are also three very bright and eloquent sceptical disputants who do their best to oppose Payrhuber’s moronic monstrosities. One of them even alerts us (and the broadcaster!) to the fact that some cancer patients might watch this and conclude that homeopathy cues cancer. Yes, TV can be dangerous!

After watching Payrhuber, I felt the urge to learn more about this man. On TV, he mentioned repeatedly his publications, so I first of all conducted a Medline search; it turns out that Medline lists not a single article in his name. However, I did find his (self-published) book: ‘HOMOEOPATHIE UND KREBS’ (HOMEOPATHY AND CANCER). It greatly impressed me – but not in a positive sense.

The preface (in English) is by Jan Scholten (who IS quite famous in the realm of homeopathy); here is a short quote from it:

[Payrhuber’s book] … is an important book for several reasons. The first reason is that it shows that homeopathy is a real healing art. Often homeopathy is seen as good for superficial, light and self-healing diseases such as colds, eczema’s, bronchitis and the like. Together with this view goes the opinion that it is not a real medicine, because it cannot treat „real diseases“. But this shows the opposite: cancer can be healed, cured with homeopathy. It shows that homeopathy can have very profound effect and can really cure deeply. Of course cancer was cured already in the past with homeopathy by famous homeopaths such as Grimmer and Resch. But Dietmar shows that it can be done in a consistent way. Homeopathy cannot be set aside as superficial anymore…

But it gets worse! Payrhuber himself is equally clear that homeopathy can cure cancer; here is a quote that I translated from his German text into English:

The book shows options to treat cancer; this is not an exclusive option of homeopathy. However, it offers an alternative for therapy-resistant and slow-responding cases treated conventionally… The question whether homeopathy is an alternative or a complementary therapy is superfluous. As the cases presented here demonstrate, homeopathy is part of medicine, a method which is more scientific than conventional medicine, because it has clear principles and laws. In certain cases or in certain phases of cancer, homeopathy is quite simply indicated! Homeopathy is holistic and puts the whole patient rather than a local symptom in the centre.

We must not keep homeopathy from cancer patients, because it offers in many cases a cure which cannot be achieved by other means.

(For those who can read German, here is the original: Das Buch zeigt Möglichkeiten auf, Krebs zu behandeln, es stellt keinen Alleinanspruch der Homöopathie dar. Es bietet allerdings alternative Möglichkeiten für therapieresistente und therapieträge Behandlungsverläufe bei konventioneller Therapie an…. 

Es erübrigt sich die Frage, ob Homöopathie eine alternative oder komplementäre Medizin ist. Wie die vorliegenden Fälle zeigen, ist sie ein Teil der Medizin, eine Methode, die „eher wissenschaftlicher ist als die Schulmedizin, weil die Homöopathie deutliche Prinzipien und Gesetze hat“. Die Homöopathie ist in bestimmten Fällen oder in bestimmten Phasen der Behandlung schlicht und einfach indiziert! Sie ist ganzheitlich, setzt den Menschen ins Zentrum und nicht das Lokalsymptom…

Die Homöopathie darf dem Patienten nicht vorenthalten werden, da sie in vielen Fällen Heilungsmöglichkeiten bietet, die auf andere Weise nicht erreicht werden können…)

As I said, Payrhuber is not famous – he is infamous!

This sad story left me with three questions:

  1. Can someone please stop Payrhuber before he does more damage to cancer patients?
  2. And can someone please tell the medical faculty of the university of Vienna (my former employer) that running a homeopathy clinic for cancer patients is not ethical?
  3. Can someone please teach journalists that, in healthcare, giving a voice to dangerous nonsense can do serious harm?

Newsweek recently reported that a herbalist has been charged with the death of a 13-year-old diabetic boy. Allegedly, the therapist replaced the boy’s insulin with herbal remedies. Tim Morrow, 83, was charged with

  1. child abuse causing death
  2. and with practicing medicine without a license.

Morrow stated that god had guided him to use herbs rather than conventional medicine and that he successfully treated treat his own prostate cancer in this way. Marrow can be seen on multiple YouTube videos from his ‘University of Common Sense’ promoting his bizarre ideas of health and disease.

Perhaps god also guided Marrow to make lots of money? He runs regular seminars and a thriving herbal on-line business, the ‘Common Sense Herbal Products‘. There are few ailments, for which ‘Common Sense Herbal Products’ do not seem to offer a herbal cure.

One of the remedies, ‘Pancreas Reg‘, for instance, claims to “act as natural insulin”. The 270 Tablets tub of this product costs US $74.22. It is easy to see, I find, how bold claims attract gullible customers depriving them not just of their money but also of their health.

Morrow started treating the boy suffering from Type 1 diabetes after he met his mother at one of his seminars. When the boy subsequently became semi-comatose, Morrow told his parents to treat their son with his herbal remedies rather than insulin which had been prescribed by qualified medical doctors. The boy, Edgar L., died only hours later. There is little doubt that he would have survived, if he had undergone conventional treatment, the medical examiner concluded.

“The allegations in this case underscore the serious health and safety risks of taking medical advice from someone who lacks a license and the proper training that goes with it,” the medical examiner said in a statement. “No family should have to suffer the tragedy of losing a child because of irresponsible, un-credentialed medical advice.”

On this blog, during lectures etc., I often stress that by far the biggest danger of seemingly harmless alternative therapies is that they are used to replace effective treatments for serious conditions. Diabetes is such a condition, and there are numerous instances where the advice of incompetent practitioners has endangered the lives of diabetics.

Three examples will have to suffice as examples of the plethora of such unethical neglect:

  • In homeopathy, diabetes is seen as a reflection of the body’s inability to function optimally. There is an imbalance that results in the body’s incapacity to effectively utilize the insulin that it produces, or to produce sufficient insulin for its needs. While symptoms often disappear after conventional treatment, the vital force does not. Homoeopathy can be used effectively in the treatment of diabetes. Here we mainly concentrate on functioning of the pancreas in efficient insulin production. The metabolic condition of a patient suffering from diabetes requires both therapeutic and nutritional measures to correct the illness. Homeopathy can regulate sugar metabolism while helping to resolve the metabolic disturbances that lead to diabetes. Furthermore, homeopathy helps stimulate the body’s self-healing powers in order to prevent complications such as open leg sores and other dysfunctions of the blood vessel, loss of vision, kidney failure. Homeopathic treatment does not target one illness, an organ, a body part or a symptom. Remedies are prescribed based on an assembly of presenting symptoms, their stresses in life.”
  • Management of Blood sugar. The commonly used remedies are Uranium Nitricum, Phosphoric Acid, Syzygium Jambolanum, Cephalandra Indica etc. These are classical Homeopathic remedies. These are used in physiologically active doses such as Mother tincture, 3x etc. depending up on the level of the blood sugar and the requirement of the patient. Several pharmaceutical companies have also brought in propriety medicines with a combination of the few Homeopathic medicines. Biochemic remedies which is a part of Homeopathy advocates Biocombination No 7 as a specific for Diabetes. Another Biochemic medicine Natrum Phos 3x is widely used with a reasonable success in controlling the blood sugar. Scientific studies on the impact of homeopathic medicines in bringing down blood sugar are limited, but many of the above remedies have some positive effects either as a stand-alone remedy or as an adjunct along with other medications.”
  • Modern medicine has no  permanent cure for diabetes but alternative medicines like yoga ,mudra,ayurveda is very useful to control and even cure diabetes.Ayurveda is an alternative medicine to cure diabetes.”

But these are very rare instances!!!

That’s what apologists usually respond.

Yet, the truth is that NOBODY knows how often such harm occurs.

Why?

There is no monitoring system anywhere that would provide such information.
