Cranio-sacral therapy has been a subject on this blog before, for instance here, here and here. The authors of this single-blind, randomized trial explain in the introduction of their paper that “cranio-sacral therapy is an alternative and complementary therapy based on the theory that restricted movement at the cranial sutures of the skull negatively affect rhythmic impulses conveyed through the cerebral spinal fluid from the cranium to the sacrum. Restriction within the cranio-sacral system can affect its components: the brain, spinal cord, and protective membranes. The brain is said to produce involuntary, rhythmic movements within the skull. This movement involves dilation and contraction of the ventricles of the brain, which produce the circulation of the cerebral spinal fluid. The theory states that this fluctuation mechanism causes reciprocal tension within the membranes, transmitting motion to the cranial bones and the sacrum. Cranio-sacral therapy and cranial osteopathic manual therapy originate from the observations made by William G. Sutherland, who said that the bones of the human skeleton have mobility. These techniques are based mainly on the study of anatomic and physiologic mechanisms in the skull and their relation to the body as a whole, which includes a system of diagnostic and therapeutic techniques aimed at treatment and prevention of diseases. These techniques are based on the so-called primary respiratory movement, which is manifested in the mobility of the cranial bones, sacrum, dura, central nervous system, and cerebrospinal fluid. The main difference between the two therapies is that cranial osteopathy, in addition to a phase that works in the direction of the lesion (called the functional phase), also uses a phase that worsens the injury, which is called structural phase.”
With this study, the researchers wanted to evaluate the effects of cranio-sacral therapy on disability, pain intensity, quality of life, and mobility in patients with low back pain. Sixty-four patients with chronic non-specific low back pain were assigned to an experimental group receiving 10 sessions of craniosacral therapy, or to the control group receiving 10 sessions of classic massage. Craniosacral therapy took 50 minutes and was conducted as follows: With pelvic diaphragm release, palms are placed in transverse position on the superior aspect of the pubic bone, under the L5–S1 sacrum, and finger pads are placed on spinal processes. With respiratory diaphragm release, palms are placed transverse under T12/L1 so that the spine lies along the start of fingers and the border of palm, and the anterior hand is placed on the breastbone. For thoracic inlet release, the thumb and index finger are placed on the opposite sides of the clavicle, with the posterior hand/palm of the hand cupping C7/T1. For the hyoid release, the thumb and index finger are placed on the hyoid, with the index finger on the occiput and the cupping finger pads on the cervical vertebrae. With the sacral technique for stabilizing L5/sacrum, the fingers contact the sulcus and the palm of the hand is in contact with the distal part of the sacral bone. The non-dominant hand of the therapist rested over the pelvis, with one hand on one iliac crest and the elbow/forearm of the other side over the other iliac crest. For CV-4 still point induction, thenar pads are placed under the occipital protuberance, avoiding mastoid sutures. Classic massage protocol was compounded by the following sequence techniques of soft tissue massage on the low back: effleurage, petrissage, friction, and kneading. The maneuvers are performed with surface pressure, followed by deep pressure and ending with surface pressure again. The techniques took 30 minutes.
Disability (Roland Morris Disability Questionnaire RMQ, and Oswestry Disability Index) was the primary endpoint. Other outcome measures included the pain intensity (10-point numeric pain rating scale), kinesiophobia (Tampa Scale of Kinesiophobia), isometric endurance of trunk flexor muscles (McQuade test), lumbar mobility in flexion, hemoglobin oxygen saturation, systolic blood pressure, diastolic blood pressure, hemodynamic measures (cardiac index), and biochemical analyses of interstitial fluid. All outcomes were measured at baseline, after treatment, and one-month follow-up.
No statistically significant differences were seen between groups for the main outcome of the study, the RMQ. However, patients receiving craniosacral therapy experienced greater improvement in pain intensity (p ≤ 0.008), hemoglobin oxygen saturation (p ≤ 0.028), and systolic blood pressure (p ≤ 0.029) at immediate- and medium-term and serum potassium (p = 0.023) level and magnesium (p = 0.012) at short-term than those receiving classic massage.
The authors concluded that 10 sessions of cranio-sacral therapy resulted in a statistically greater improvement in pain intensity, hemoglobin oxygen saturation, systolic blood pressure, serum potassium, and magnesium level than did 10 sessions of classic massage in patients with low back pain.
Given the results of this study, the conclusion is surprising. The primary outcome measure failed to show an inter-group difference; in other words, the results of this RCT were essentially negative. To use secondary endpoints – most of which are irrelevant for the study’s aim – in order to draw a positive conclusion seems odd, if not misleading. These positive findings are most likely due to the lack of patient-blinding or to the 200 min longer attention received by the verum patients. They are thus next to meaningless.
In my view, this publication is yet another example of an attempt to turn a negative into a positive result. This phenomenon seems embarrassingly frequent in alternative medicine. It goes without saying that it is not just misleading but also dishonest and unethical.
Dengue is a viral infection spread by mosquitoes; it is common in many parts of the world. The symptoms include fever, headache, muscle/joint pain and a red rash. The infection is usually mild and lasts about a week. In rare cases it can be more serious and even life threatening. There’s no specific treatment – except for homeopathy; at least this is what many homeopaths want us to believe.
And, of course, we don’t want to listen to just any odd homeopath, we want true experts to tell us the truth – for instance, experts like Dr. R.K. Manchanda, Deputy Director(Homoeopathy), Directorate of ISM & Homoeopathy, Govt. of NCT of Delhi and Dr. Surinder Verma, Assistant Director (Homoeopathy), Directorate of ISM & Homoeopathy, Govt. of NCT of Delhi. They authored an article which states the following:
There are about 25 homoeopathic drugs available for the treatment of dengue fever. These are Aconite., Arnica, Arsenic-alb., Arum-tri., Baptisia., Belladonna., Bryonia., Cantharis., China officinalis Colocynthis., Eupatorium perfoliatum., Ferrum metallicum., Gelsemium., Hamamelis., Ipecac., Lachesis, Merc-sol, Nux vomica., Podophyllum., Rhus toxicodendron., Rhus-venenata., Sanicula., Secale cornutum and Sul-acidum. These drugs had been successfully used by various homeopaths across the globe for its treatment and management. In 1996 during the epidemic of dengue in Delhi Eupatorium perfoliatum was found most effective.
Sadly, the article does not provide any evidence. A quick Medline search located one (!) single trial on the subject. Here is the abstract:
A double-blind, placebo-controlled randomized trial of a homeopathic combination medication for dengue fever was carried out in municipal health clinics in Honduras. Sixty patients who met the case definition of dengue (fever plus two ancillary symptoms) were randomized to receive the homeopathic medication or placebo for 1 week, along with standard conventional analgesic treatment for dengue. The results showed no difference in outcomes between the two groups, including the number of days of fever and pain as well as analgesic use and complication rates. Only three subjects had laboratory confirmed dengue. An interesting sinusoidal curve in reported pain scores was seen in the verum group that might suggest a homeopathic aggravation or a proving. The small sample size makes conclusions difficult, but the results of this study do not suggest that this combination homeopathic remedy is effective for the symptoms that are characteristic of dengue fever.
This is a 2007 study by a well-known US homeopath. Its results fail to confirm that homeopathy is effective for Dengue. So, surely the homeopathic community has since stopped claiming that homeopathy is an option for this infection!
No, you guessed correctly, they continue claiming that homeopathy works for Dengue. Currently, there are about half a million websites doing exactly that. An example is this article published YESTERDAY (!):
Alopathy is no more the only solution for Dengue these days. Especially in a place like Bengaluru where doctors and medicines are both expensive, residents have now turned to a cheaper and an effective alternative-Homeopathy to combat Dengue.People have been milling Homeopathy clinics and hospitals for an antidote. Dr Sudhir Babu of Javaji Advanced Homeopathy said, “People ask for some cure to keep the disease at bay. We do in fact have medicines to help build immunity against the ailment.”The dosage is for four or five days and is taken daily. Homeopathy has now become a trusted alternative in the field of medicine, especially because of its easy acceptibility among children and adults. According to a survey by IMRB, 100% people know about this form of medicine and 92% perceive it as a reputed form of treatment. The medicines that are administered depending on the symmptoms of Dengue Fever are Aconitum Napellus, Arsenicum Album, Belladonna, Bryonia Alba, Cantharis, Cinchona Officinalis, Eupatorium Perfoliatum, Gelsemium, Ipecacuanha, Nux Vomica, Rhus Toxicodendron and Rhus Venenata.
What I found particularly impressive here is the way popularity has been used to replace evidence. This, I think, begs several questions:
- How long will homeopaths continue treating self-limiting conditions to claim success based no nothing but their natural history?
- How long will they continue to lie to the public?
- How long will they refuse to learn from the evidence?
- How long will they ignore even the most fundamental rules of medical ethics?
- How long will we let them get away with all this?
A new Cochrane review evaluated the effectiveness and safety of Chinese herbal medicines (CHM) in the treatment of menopausal symptoms. Its authors conducted a thorough search for randomised controlled trials (RCTs) comparing the effectiveness of CHM with placebo, hormone therapy (HT), pharmaceutical drugs, acupuncture, or another CHM formula in women suffering from menopausal symptoms.
Two review authors independently assessed 864 studies for eligibility. Data extractions were performed by them with disagreements resolved through group discussion and clarification of data or direct contact with the study authors. Data analyses were performed in accordance with Cochrane Collaboration guidelines.
In total, 22 RCTs (2902 women) could be included. When CHM was compared with placebo (8 RCTs), there was little or no evidence of a difference between the groups for the following outcomes: hot flushes per day (MD 0.00, 95% CI -0.88 to 0.89; 2 trials, 199 women; moderate quality evidence); hot flushes per day assessed by an overall hot flush score in which a difference of one point equates to one mild hot flush per day (MD -0.81 points, 95% CI -2.08 to 0.45; 3 RCTs, 263 women; low quality evidence); and overall vasomotor symptoms per month measured by the Menopause-Specific Quality of Life questionnaire (MENQOL, scale 0 to 6) (MD -0.42 points; 95% CI -1.52 to 0.68; 3 RCTs, 256 women; low quality evidence). In addition, results from individual studies suggested there was no evidence of a difference between the groups for daily hot flushes assessed by severity (MD -0.70 points, 95% CI -1.00, -0.40; 1 RCT, 108 women; moderate quality evidence); or overall monthly hot flushes scores (MD -2.80 points, 95% CI -8.93 to 3.33; 1 RCT, 84 women; very low quality evidence); or overall daily night sweats scores (MD 0.07 points, 95% CI -0.19 to 0.33, 1 RCT, 64 women; low quality evidence); or overall monthly night sweats scores (MD 1.30 points, 95% CI -1.76 to 4.36, 1 RCT, 84 women; very low quality evidence). However, one study reported that overall monthly vasomotor symptom scores were lower in the CHM group (MD -4.79 points, 95% CI -5.52 to -4.06; 1 RCT, 69 women; low quality evidence).
When CHM was compared with HT (10 RCTs), only two RCTs reported monthly vasomotor symptoms using MENQOL. It was uncertain whether CHM reduces vasomotor symptoms (MD 0.47 points, 95% CI -0.50 to 1.44; 2 RCTs, 127 women; very low quality evidence).
Adverse effects were not fully reported in the included studies. Adverse events reported by women taking CHM included mild diarrhoea, breast tenderness, gastric discomfort and an unpleasant taste. Effects were inconclusive because of imprecise estimates of effects: CHM versus placebo (RR 1.51; 95% CI 0.69 to 3.33; 7 trials, 705 women; I² = 40%); CHM versus HT (RR 0.96; 95% CI 0.66 to 1.39; 2 RCTs, 864 women; I² = 0%); and CHM versus specific conventional medications (such as Fluoxetine and Estazolam) (RR 0.20; 95% CI 0.03 to 1.17; 2 RCTs, 139 women; I² = 61%).
The authors concluded: We found insufficient evidence that Chinese herbal medicines were any more or less effective than placebo or HT for the relief of vasomotor symptoms. Effects on safety were inconclusive. The quality of the evidence ranged from very low to moderate; there is a need for well-designed randomised controlled studies.
This review seems well done and reports clear findings. The fact that there was insufficient evidence for CHM is probably no surprise to most readers of this blog. However, I would like to draw your attention to a finding that could easily be missed: most of the primary studies failed to mention adverse effects; to be perfectly clear: they did not state “there were no adverse effects”, but they simply did not mention the subject of adverse effects at all.
In my view, this is a breach of research ethics. I have been banging on about this phenomenon for some time now, because I think it is important. Many if not most clinical trials in this area neglect reporting adverse effects. This means that we get an entirely misleading impression about the safety of the treatments in question. Reviewers of such studies are bound to conclude that they seem to be safe, while, in fact, researchers have only been withholding crucial information from us.
The solution to this fast-growing problem would be simple: trialists must be forced to fully report adverse effects. This is less complicated that it might seem: journal editors must insist that all authors fully report adverse effects of alternative treatments. Even if there were none at all – a very unlikely proposition if you think about it – they must disclose this fact.
“THERE IS A SUCKER BORN EVERY MINUTE” – this quote is commonly attributed to P.T.Barnum. If he really coined the sentence, he certainly did not think of the little cups sucking in the skin of patients undergoing cupping therapy. Yet, the recent media coverage of cupping made me think of this quote. The suckers here are not the therapeutic devices employed for cupping but the athletes, the journalists and the general public.
In my experience, athletes are often very worried about their body. This is perhaps understandable but, at the same time, it makes them the ideal victims of all types of charlatans. I am therefore not really surprised to see that some Olympic athletes fell for cupping. They want to use every means allowed by the doping rules to enhance their performance. Cupping therapists claim all sorts of strange and unwarranted things, and some athletes seem to be gullible enough to believe them. Belief can perhaps not move mountains, but it might give you the edge in an Olympic competition.
The ‘beauty’ of cupping when applied to an athlete’s body is that its traces are so publicly visible. During Olympic games, this means that the entire world knows within hours about the cupping-habit of an athlete. What could be more exciting for journalists than these odd cupping marks decorating the muscular bodies of some Olympic athletes? If they are not worth a good story, what is?
There is hardly a newspaper on the planet that did not jump on this band-waggon full of snake oil – there is a sucker born every minute! Nothing wrong with reporting what is happening at the Olympic games, of course. But what has sometimes been reported in the press about cupping beggars belief. Rarely have I read so much nonsense about an alternative therapy in such a short time.
Do you need an example? The DAILY MAIL is as good – or rather bad? – as most; this is what the DM published yesterday on the subject: Chinese media have been cheering cupping’s appearance at the Olympics as proof of the value of traditional culture, with both the official Xinhua news agency and Communist Party mouthpiece People’s Daily touting the soft-power benefits. “Chinese traditions and products proliferate Olympic village”, read one headline on the People’s Daily website. Ding Hui, manager of the Lily Spring Health & Spa in Beijing, said she has seen a 30 percent jump in clients asking for cupping treatment since the Olympics started. “Even though Chinese people have known about it for a long time, they see a great athlete does it and see it really works,” Ding said. “For athletes, they build up harmful lactic acid in the body and cupping can help relieve it.”
You might think that, when reporting about a weird therapy, journalists have little options but to interview weird ‘experts’ relating cupping to even weirder ‘energies’, ‘life forces’, ‘meridians’, yin and yang, TCM, etc. But you would be wrong. They do of course have other options; they would only have needed to log on Medline to find hundreds of references related to the subject. If they had done that, they would even have found an abstract of mine that might have answered many of their question and would have clarified many of the questions about the scientific evidence for or against cupping. Here it is:
The objective of this study was to assess the evidence for or against the effectiveness of cupping as a treatment option for pain. Fourteen databases were searched. Randomized clinical trials (RCTs) testing cupping in patients with pain of any origin were considered. Trials using cupping with or without drawing blood were included, while trials comparing cupping with other treatments of unproven efficacy were excluded. Trials with cupping as concomitant treatment together with other treatments of unproven efficacy were excluded. Trials were also excluded if pain was not a central symptom of the condition. The selection of studies, data extraction and validation were performed independently by three reviewers. Seven RCTs met all the inclusion criteria. Two RCTs suggested significant pain reduction for cupping in low back pain compared with usual care (P < .01) and analgesia (P < .001). Another two RCTs also showed positive effects of cupping in cancer pain (P < .05) and trigeminal neuralgia (P < .01) compared with anticancer drugs and analgesics, respectively. Two RCTs reported favorable effects of cupping on pain in brachialgia compared with usual care (P = .03) or heat pad (P < .001). The other RCT failed to show superior effects of cupping on pain in herpes zoster compared with anti-viral medication (P = .065). Currently there are few RCTs testing the effectiveness of cupping in the management of pain. Most of the existing trials are of poor quality. Therefore, more rigorous studies are required before the effectiveness of cupping for the treatment of pain can be determined.
With just one further click on their keyboard, they would have been able to read the full text of my article which cautioned in no uncertain terms: The number of trials and the total sample size are too small to distinguish between any nonspecific or specific effects, which preclude any firm conclusions. Moreover, the methodological quality was often poor.
Sadly, few journalists seemed to have bothered to do this tiny bit of research. Why? Surely, journalists are trained to investigate their subject before putting pen to paper! Yes, most of them are, but a headline like THE EVIDENCE FOR CUPPING IS FLIMSY does not sell newspapers. The public wants something much more interesting – there is a sucker born every minute!
And what should be wrong with that? People deserve a bit of an entertaining story about their Olympic idols! Perhaps, but there is a downside, of course. The media-hype of the last week will create a demand. The general public will now want the very therapy that helped athletes win gold medals (never mind that it didn’t). Thanks to the media, cupping is now destined to become the alternative therapy of the future.
And what is wrong with that? Quite a lot, I think!
For one, quacks will jump on this fast-moving band-waggon filled with snake oil and try to divert as much cash as they can from their victims’ into their own bank accounts. Perhaps that would not be the worst effect. The worst would be, if some people believe what some quacks will undoubtedly tell them, that cupping is effective (“they see a great athlete does it and see it really works”) for all sorts of conditions, including serious diseases (“Cupping has also been used by some as an alternative treatment for cancer.”) – THERE IS A SUCKER BORN EVERY MINUTE (and some might even die sucking)!
When a leading paper like the FRANKFURTER ALLGEMEINE ZEITUNG (FAZ) publishes in its science pages (!!!) a long article on homeopathy, this is bound to raise some eyebrows, particularly when the article in question was written by the chair of the German Association of Homeopaths (Deutscher Zentralverein homöopathischer Ärzte) and turns out to be a completely one-sided and misleading white-wash of homeopathy. The article (entitled DIE ZEIT DES GEGENEINANDERS IST VORBEI which roughly translates into THE DAYS OF FIGHTING ARE OVER) is in German, of course, so I will translate the conclusions for you here:
The critics [of homeopathy] … view the current insights of conventional pharmacology as some type of dogma. For them it is unthinkable that a high potency can cause a self-regulatory and thus healing effect on a sick person. Homeopathic doctors are in their eyes “liars”. Based on this single argument, the critics affirm further that therefore no positive studies can exist which prove the efficacy of homeopathy beyond placebo. After all, high potencies “contain nothing”. The big success of homeopathy is a sore point for them, because efficacious high potencies contradict their seemingly rational-materialistic world view. Research into homeopathy should be stopped, the critics say. This tune is played unisono today by critics who formerly claimed that homeopaths block the research into their therapy. The fact is: homeopathic doctors are today in favour of research, even with their own funds, whenever possible. Critics meanwhile demand a ban.
In the final analysis, homeopathic doctors do not want a fight but a co-operation of the methods. Homeopathy creates new therapeutic options for the management of acute to serious chronic diseases. In this, homeopathy is self-evidently not a panacea: the physician decides with every patient individually, whether homeopathy is to be employed as an alternative, as an adjunct, or not at all. Conventional diagnostic techniques are always part of the therapy.
END OF QUOTE[For those readers who read German, here is the German original:
Die Kritiker … betrachten die heutigen Erkenntnisse der konventionellen Pharmakologie als eine Art Dogma. Für sie ist es undenkbar, dass eine Hochpotenz einen selbstregulativen und damit heilenden Effekt bei einem kranken Menschen auslösen kann. Homöopathische Ärzte sind in ihren Augen “Lügner”. Von diesem einen Argument ausgehend, wird dann weiter behauptet, dass es deshalb gar keine positiven Studien geben könne, die eine Wirksamkeit der Homöopathie über einen Placebo-Effekt hinaus belegen. Schließlich sei in Hochpotenzen “nichts drin”. Der große Erfolg der Homöopathie ist ihnen ein Dorn im Auge, weil wirksame Hochpotenzen ihrem vermeintlich rational-materialistischen Weltbild widersprechen. Die Erforschung der Homöopathie solle gestoppt werden, heißt es. Unisono wird diese Melodie von Kritikern heute gespielt, von ebenjenen Kritikern, die früher behaupteten, die homöopathischen Ärzte sperrten sich gegen die Erforschung ihrer Heilmethode. Fakt ist: Heute setzen sich homöopathische Ärzte für die Forschung ein, auch mit eigenen Mitteln, soweit es ihnen möglich ist. Kritiker fordern mittlerweile das Verbot.
Letztlich geht es homöopathischen Ärzten allerdings nicht um ein Gegeneinander, sondern um ein Miteinander der Methoden. Durch die Homöopathie entstehen neue Therapieoptionen bei der Behandlung von akuten bis hin zu schweren chronischen Erkrankungen. Dabei ist die ärztliche Homöopathie selbstverständlich kein Allheilmittel: Bei jedem erkrankten Patienten entscheidet der Arzt individuell, ob er die Homöopathie alternativ oder ergänzend zur konventionellen Medizin einsetzt – oder eben gar nicht. Die konventionelle Diagnostik ist stets Teil der Behandlung.]
While translating this short text, I had to smile; here are some of the reasons why:
- ‘conventional pharmacology’ is a funny term; do homeopaths think that there also is an unconventional pharmacology?
- ‘dogma’… who is dogmatic, conventional medicine which changes almost every month, or homeopathy which has remained essentially unchanged since 200 years?
- ‘liars’ – yes, that’s a correct term for people who use untruths for promoting their business!
- ‘Based on this single argument’… oh, I know quite a few more!
- ‘doctors are today in favour of research’ – I have recently blogged about the research activity of homeopaths.
- ‘co-operation of the methods’ – I have also blogged repeatedly about the dangerous nonsense of ‘integrative medicine’ and called it ‘one of the most colossal deceptions of healthcare today’. Hahnemann would have ex-communicated the author for this suggestion, he called homeopaths who combined the two methods ‘traitors’!!!
- ‘new therapeutic options’… neither new nor therapeutic, I would counter; to be accepted as ‘therapeutic’, one would need a solid proof of efficacy.
- ’employed as an alternative’ – would this be ethical?
- ‘Conventional diagnostic techniques are always part of the therapy’… really? I was taught that diagnosis and treatment are two separate things.
There were many comments by readers of the FAZ. Their vast majority expressed bewilderment at the idea that the chair of the German Association of Homeopaths has been given such a platform to dangerously mislead the public. I have to say that I fully agree with this view: the promotion of bogus treatments can only be a disservice to public health.
The aim of a new meta-analysis was to estimate the clinical effectiveness and safety of acupuncture for amnestic mild cognitive impairment (AMCI), the transitional stage between the normal memory loss of aging and dementia. Randomised controlled trials (RCTs) of acupuncture versus medical treatment for AMCI were identified using six electronic databases.
Five RCTs involving a total of 568 subjects were included. The methodological quality of the RCTs was generally poor. Participants receiving acupuncture had better outcomes than those receiving nimodipine with greater clinical efficacy rates (odds ratio (OR) 1.78, 95% CI 1.19 to 2.65; p<0.01), mini-mental state examination (MMSE) scores (mean difference (MD) 0.99, 95% CI 0.71 to 1.28; p<0.01), and picture recognition score (MD 2.12, 95% CI 1.48 to 2.75; p<0.01). Acupuncture used in conjunction with nimodipine significantly improved MMSE scores (MD 1.09, 95% CI 0.29 to 1.89; p<0.01) compared to nimodipine alone. Three trials reported adverse events.
The authors concluded that acupuncture appears effective for AMCI when used as an alternative or adjunctive treatment; however, caution must be exercised given the low methodological quality of included trials. Further, more rigorously designed studies are needed.
Meta-analyses like this one are, in my view, perfect examples for the ‘rubbish in, rubbish out’ principle of systematic reviews. This may seem like an unfair statement, so let me justify it by explaining the shortfalls of this specific paper.
The authors try to tell us that their aim was “to estimate the clinical effectiveness and safety of acupuncture…” While it might be possible to estimate the effectiveness of a therapy by pooling the data of a few RCTs, it is never possible to estimate its safety on such a basis. To conduct an assessment of therapeutic safety, one would need sample sizes that go two or three dimensions beyond those of RCTs. Thus safety assessments are best done by evaluating the evidence from all the available evidence, including case-reports, epidemiological investigations and observational studies.
The authors tell us that “two studies did not report whether any adverse events or side effects had occurred in the experimental or control groups.” This is a common and serious flaw of many acupuncture trials, and another important reason why RCTs cannot be used for evaluating the risks of acupuncture. Too many such studies simply don’t mention adverse effects at all. If they are then submitted to systematic reviews, they must generate a false positive picture about the safety of acupuncture. The absence of adverse effects reporting is a serious breach of research ethics. In the realm of acupuncture, it is so common, that many reviewers do not even bother to discuss this violation of medical ethics as a major issue.
The authors conclude that acupuncture is more effective than nimodipine. This sounds impressive – unless you happen to know that nimodipine is not supported by good evidence either. A Cochrane review provided no convincing evidence that nimodipine is a useful treatment for the symptoms of dementia, either unclassified or according to the major subtypes – Alzheimer’s disease, vascular, or mixed Alzheimer’s and vascular dementia.
The authors also conclude that acupuncture used in conjunction with nimodipine is better than nimodipine alone. This too might sound impressive – unless you realise that all the RCTs in question failed to control for the effects of placebo and the added attention given to the patients. This means that the findings reported here are consistent with acupuncture itself being totally devoid of therapeutic effects.
The authors are quite open about the paucity of RCTs and their mostly dismal methodological quality. Yet they arrive at fairly definitive conclusions regarding the therapeutic value of acupuncture. This is, in my view, a serious mistake: on the basis of a few poorly designed and poorly reported RCTs, one should never arrive at even tentatively positive conclusion. Any decent journal would not have published such misleading phraseology, and it is noteworthy that the paper in question appeared in a journal that has a long history of being hopelessly biased in favour of acupuncture.
Any of the above-mentioned flaws could already be fatal, but I have kept the most serious one for last. All the 5 RCTs that were included in the analyses were conducted in China by Chinese researchers and published in Chinese journals. It has been shown repeatedly that such studies hardly ever report anything other than positive results; no matter what conditions is being investigated, acupuncture turns out to be effective in the hands of Chinese trialists. This means that the result of such a study is clear even before the first patient has been recruited. Little wonder then that virtually all reviews of such trials – and there are dozens of then – arrive at conclusions similar to those formulated in the paper before us.
As I already said: rubbish in, rubbish out!
If you feel that, on this blog and elsewhere, some sceptics sometimes use harsh language, you haven’t recently read what ‘the other side’ of the debate regularly publish. A good example is ‘NATURAL NEWS’; slander and insult seem to be the daily fare of this publication. A good example is this recent article; it is so disgustingly vile that I cannot resist showing you a few passages.
START OF QUOTE
Meet the ultimate pharma whore and vaccine-toxin apologist, Dr. Paul ‘Profit’ Offit
Possibly one of the most dangerous doctors on planet Earth is Paul Offit, a man capable of creating, promoting and profiting from the most toxic “medicine” known to mankind – experimental vaccines. Not only is injecting neurotoxins into children extremely dangerous, but the whole vaccine industry is loosely regulated, and the CDC requires no proof of safety or efficacy for immunizations.
Plus, the vaccine industry has their own rigged court system so that families cannot sue the manufacturers. Anyone who lets their children be injected with mercury, formaldehyde, aluminum and MSG (contaminants found in nearly every vaccine and flu shot), is putting a ton of faith in something they should not have any faith in. The inoculation industry as a whole has been making fraudulent medical claims for more than 60 years. Vaccines and prescription medications are fast-tracked through the FDA and CDC without any tests for safety or efficacy.
That’s why about one sixth of all Americans (about 50 million) have sought out holistic care of some sort, at least once already. People are fed up with pediatricians who know nothing about nutrition or quality, non-invasive, non-chemical care. They’re also realizing that prescription meds come with side effects that are worse than the conditions being treated. That’s where scare tactic “professionals” and criminal propagandists come into play, like Dr. Paul Offit.
Never trust someone who can ‘vote themselves rich’ – like Dr. Paul ‘Offit-for-Profit’
One of the biggest scams of the century is the “RotaTeq” rotavirus vaccine. Invented by, patented by, promoted by, and worth millions in profit to Offit, the extremely toxic (oral) vaccine contains live rotavirus strains (G1, G2, G3, G4 and P1), plus highly toxic polysorbate 80 and fetal bovine serum. Scared yet? There’s more. This insane inoculation contains parts of porcine circovirus, a virus that infects pigs! This is all per the Merck website’s list of ingredients, in case you’d like to check for yourself. Want to infect your infant with all of this and help “Profit-Offit” get richer, so he can infect more infants?
Bill Gates promotes Offit in their combined attempt to mass-vaccinate the whole world and decrease the population by several billion, by injecting cancer-causing carcinogens and toxins that cause infertility. That’s the plan.
Offit works at the Children’s hospital of Philadelphia (appropriately nicknamed CHOP), and he is a founding advisory board member of the Autism Science Foundation. All this in spite of the fact that autism has been directly linked to the MMR vaccine, which contains, not coincidentally, many of the same ingredients as the RotaTeq vaccine.
The Rotavirus vaccine has never been proven to work, yet Offit made tens of millions of dollars when he sold the patent. Offit has direct financial ties to Merck, and formerly served on the CDC’s Advisory Committee on Immunization Practices, a position which has come into question as an extreme conflict of interest. That job entailed Offit creating the market for the rotavirus vaccine, which means he basically voted himself rich in the process.
Paul “Profit” Offit is quoted as saying he could get “10,000 vaccines at once” and be fine, knowing even a dozen would probably kill him or maim him for life…
END OF QUOTE
Such extreme diatribe does, of course, not deserve a comment. However, I want to stress that Paul Offit is one of the leading paediatrician and immunization expert in the US; his reputation is undisputed (except, of course, in circles of deranged loons) and he recently published a book on alternative medicine, entitled ‘DO YOU BELIEVE IN MAGIC’, that I highly recommend.
A survey published in 2011 showed that one-third of Danish hospitals offered alternative therapies. In total, 38 hospitals offered acupuncture and one Eye Movement Desensitization and Reprocessing Light Therapy. The most commonly reported reason for offering CAM was “scientific evidence”.
Many readers of this blog might be amazed with both the high level of alternative medicine presence in Danish hospitals and the notion that this was due to ‘scientific evidence’. A recent article provides even more surprises about the Danish alternative medicine scene.
It revealed that 8 out of 10 Danes are interested in using some form of alternative medicine…Some 67 percent of Danes say the national healthcare system should be more open to alternative healing practices, such as homeopathy, acupuncture or chiropractic, and 60 percent would like to see these treatments covered by the public health insurance system. More than half of the 6,000 respondents believe alternative therapies can be just as effective as traditional medicine.
Charlotte Yde, the chairwoman at Sundhedsrådet, which is the umbrella organisation for alternative practitioners in Denmark, contends many Danes feel frustrated because they cannot freely discuss alternative treatment with their doctors. Alternative treatment researcher Helle Johannessen agrees that Danish doctors should openly discuss alternative medicine options with patients. “In other European countries doctors use alternative treatment to a much greater extent than doctors in Denmark,” Johannessen told DR. “[International experience] shows that some forms of alternative therapy can improve quality of life and reduce anxiety and nausea in cancer patients.”
This, it seems to me, is little more than a bonanza of fallacious thinking and misleading information.
- The notion that popularity of a therapy has anything to do with its usefulness is a classical fallacy.
- The notion that belief determines efficacy (More than half of the 6,000 respondents believe alternative therapies can be just as effective as traditional medicine.) or vice versa is complete nonsense.
- The notion that many Danes … cannot freely discuss alternative treatment with their doctors is misleading: patients can discuss what they feel like with whom they feel like.
- The notion that in other European countries doctors use alternative treatment to a much greater extent than doctors in Denmark is also misleading: there are many European countries where LESS alternative therapies are being paid for via the public purse.
- Finally, the notion that that some forms of alternative therapy can improve quality of life and reduce anxiety and nausea in cancer patients – even if it were correct – does not mean that ALL alternative therapies are efficacious, safe, or cost-effective.
Who cares about Denmark?
Why should this be important?
Well, the Danes might care, and it is important because it provides an excellent example of how promoters of bogus treatments tend to argue – not just in Denmark, but everywhere. Unfortunately, politicians all too often fall for such fallacious notions. For them, a popular issue is a potential vote-winner. Within medical systems that are notoriously strapped for money, the looser will inevitably be optimal healthcare.
The UK petition to ban homeopathy for animals has so far achieved well over 3 000 signatures. Remarkably, it also prompted a reaction from the Faculty of Homeopathy which I reproduce here in full:
Homeopathy has a long history of being used successfully in veterinary practice for both domestic and farm animals. The EU recommends its use in its regulations on organic farms and is funding research into veterinary homeopathy as a way of reducing antibiotic use in livestock. It is nonsense to suggest that responsible pet owners and farmers are unable to distinguish between effective and ineffective medicines; they continue to use homeopathy because they see its benefits.
Membership of the Faculty of Homeopathy (VetMFHom) is bestowed on qualified veterinary surgeons who have completed a minimum of three years study of homeopathy and after a rigorous examination procedure. It differentiates the qualified veterinary homeopath from an unlicensed healer.
In a statement, the Royal College of Veterinary Surgeons said “… homeopathy is currently accepted by society and recognised by UK medicines legislation, and does not, in itself, cause harm to animals”. Before going on to say it could see no justification for banning veterinary surgeons from practising homeopathy.
In an age when antibiotic resistance is such an important issue, veterinary surgeons and farmers who have found they can limit the use of these drugs by using homeopathy should be applauded and not attacked.

Such sentiments resonate with those of the UK’s most influential supporter of homeopathy, Prince Charles. Speaking at a global leaders summit on antimicrobial resistance, Prince Charles recently warned that Britain faced a “potentially disastrous scenario” because of the “overuse and abuse” of antibiotics. The Prince explained that he had switched to organic farming on his estates because of the growing threat from antibiotic resistance and now treats his cattle with homeopathic remedies rather than conventional medication. “As some of you may be aware, this issue has been a long-standing and acute concern to me,” he told delegates from 20 countries at The Royal Society in London. “I have enormous sympathy for those engaged in the vital task of ensuring that, as the world population continues to increase unsustainably and travel becomes easier, antibiotics retain their availability to overcome disease… It must be incredibly frustrating to witness the fact that antibiotics have too often simply acted as a substitute for basic hygiene, or as it would seem, a way of placating a patient who has a viral infection or who actually needs little more than patience to allow a minor bacterial infection to resolve itself.”
It seems that both Prince Charles and Peter Gregory believe that homeopathy can be employed to reduce the use of antibiotics in animals. So, let’s analyse this hypothesis a little closer.
The way I see it, the belief must be based on one of two assumptions:
- Homeopathic remedies are effective in treating or preventing bacterial infections.
- If farmers administer homeopathic remedies to their life-stock, they are less likely to administer unnecessary antibiotics.
Assumption No 1 can be rejected without much further debate; there is no evidence whatsoever that homeopathic remedies have antibiotic efficacy. In fact, the consensus today is that highly diluted homeopathic remedies are pure placebos.
Assumption No 2, however, might be more plausible and therefore deserves further scrutiny. If we do not tell the farmers nor the vets that homeopathic remedies are placebos, if, in other words, we mislead them to think they are efficacious medicines, they might give them to their animals instead of antibiotics. Consequently, the usage of antibiotics in animals would decrease. This strategy sounds plausible but, on second thought, it has many serious drawbacks:
- The truth has a high value in itself which we would disregard at our peril.
- One might not be able to keep the truth from the farmers and even less able to hide it from vets.
- If we mislead farmers and vets, we must also mislead the rest of the population; this means lots of people might start using homeopathic placebos even for serious conditions.
- Misleading farmers, vets and the rest of the population is clearly unethical.
- Misleading farmers and vets in this way might not be necessary; if there is abuse of antibiotics in farming, we ought to tackle this phenomenon directly.
- Misleading farmers and vets might be dangerous for at least two reasons: firstly, animals who truly need antibiotics would not receive adequate treatment; secondly, farmers and vets might eventually become convinced that homeopathy is efficacious and would therefore use it in all sorts of situations, even for serious diseases of humans.
Whichever way I twist and turn the assumption No 2, I fail to arrive at anything remotely sensible. But this leaves me with a huge problem: I would have to conclude that both the Veterinary Dean, Faculty of Homeopathy and the heir to the throne are bonkers… and, surely, this cannot be right either!!!
It would be easy to continue this series on ‘tricks of the trade’ for quite a while. But this might get boring, and I have therefore decided to call it a day. So here is the last instalment (feel free to post further tricks that you may know of [in the comments section below]):
CRITICS DON’T UNDERSTAND
It is almost inevitable that, sooner or later, someone will object to some aspect of alternative medicine. In all likelihood, his or her arguments are rational and based on evidence. If that happens, the practitioner has several options to save his bacon (and income). One of the easiest and most popular is to claim that “of course, you cannot agree with me because you do not understand!”
The practitioner now needs to explain that, in order to achieve the level of expertise he has acquired, one has to do much more than to rationalise or know about science. In fact, one has to understand the subject on a much deeper level. One has to immerse oneself into it, open one’s mind completely and become a different human being altogether. This cannot be achieved by scientific study alone; it requires years of meditative work. And not everyone has the ability to go down this difficult path. It takes a lot of energy, insight and vision to become a true healer. A true Deepak Chopra is not born but trained through hard work, dedication and concentration.
Critics who disagree are really to be pitied. They fail to exist on quite the same level as those who ‘are in the know’. Therefore one must not get annoyed with those who disagree, they cannot understand because they have not seen the light.
My advice is to start thinking critically and read up about the NO TRUE SCOTSMAN FALLACY; this will quickly enable you to look beyond the charisma of these gurus and expose their charlatanry to the full.
RESEARCH IS BEING SUPRESSED
Some critics stubbornly insist on evidence for the therapeutic claims made by quacks. That attitude can be awkward for the alternative practitioner – because usually there is no good evidence.
Cornered in this way, quacks often come up with a simple but effective conspiracy theory: the research has been done and it has produced fabulous results, but it has been supressed by… well, by whoever comes to mind. Usually BIG PHARMA or ‘the scientific establishment’ have to be dragged out into the frame again.
According to this theory, the pharmaceutical industry (or whoever comes in handy) was so shaken by the findings of the research that they decided to make it disappear. They had no choice, really; the alternative therapy in question was so very effective that it would have put BIG PHARMA straight out of business for ever. As we all know BIG PHARMA to be evil to the core, they had no ethical or moral qualms about committing such a crime to humanity. Profits must come before charity!
My advice is to explain to such charlatans that such conspiracy theories do, in fact, merely prove is that the quack’s treatment is not effective against their prosecution complex.
CRITICS ARE BOUGHT AND CORRUPT
If critics of alternative medicine become threatening to the quackery trade, an easy and much-used method is to discredit them by spreading lies about them. If the above-mentioned ploy “they cannot understand” fails to silence the nasty critics, the next step must be to claim they are corrupt. Why else would they spend their time exposing quackery?
Many people – alternative practitioners included – can only think of financial motivations; the possibility that someone might do a job for altruistic reasons does not occur to them. Therefore, it sounds most plausible that the critics of alternative medicine are doing it for money – after all, the quacks also quack for money.
My advice to potential users of alternative medicine who are confused by such allegations: do your own research and find out for yourself who is bought by whom and who has a financial interest in quackery selling well.
EVEN NOBEL PRIZE WINNERS AGREE WITH US
It is true, there are some Nobel Prize winners who defend homeopathy or other bogus treatments. Whenever this happens, the apologists of alternative medicine have a field day. They then cite the Nobel laureate ad nauseam and imply that his or her views prove their quackery to be correct.
Little do they know that they are merely milking yet another classical fallacy and that such regrettable events merely demonstrate that even bright people can make mistakes.
My advice is to check what the Nobel laureate actually said – more often than not, it turns out that a much-publicised quote is, in fact, a misquote – and what his or her qualifications are for making such a statement; a Nobel Prize in literature, for instance, is not a sufficient qualification for commenting on healthcare issues.
