Dietary supplements (DS) are heavily promoted usually with the claim that they have stood the test of time and that they are natural and hence harmless. Unsurprisingly, their use has become very wide-spread. A new study determined the use of DSs, factors associated with DS use, and reasons for use among U.S. college students.
College students (N = 1248) at 5 U.S. universities were surveyed. Survey questions included descriptive demographics, types and frequency of DS used, reasons for use and money spent on supplements. Supplements were classified using standard criteria. Logistic regression analyses examined relationships between demographic and lifestyle factors and DS use.
Sixty-six percent of college students surveyed used DS at least once a week, and 12% consumed 5 or more supplements a week. Forty-two percent used multivitamins/multiminerals, 18% vitamin C, 17% protein/amino acids and 13% calcium at least once a week. Factors associated with supplement use included dietary patterns, exercise, and tobacco use. Students used supplements to promote general health (73%), provide more energy (29%), increase muscle strength (20%), and enhance performance (19%).
The authors of this survey concluded that college students appear more likely to use DS than the general population and many use multiple types of supplements weekly. Habits established at a young age persist throughout life. Therefore, longitudinal research should be conducted to determine whether patterns of DS use established early in adulthood are maintained throughout life. Adequate scientific justification for widespread use of DS in healthy, young populations is lacking.
Another new study investigated the use of DSs in 334 dancers from 53 countries, who completed a digitally based 35-question survey detailing demographic information and the use of DSs. Supplement use was prevalent amongst this international cohort, with 48% reporting regular DSs use. Major motives for supplement use were to improve health, boost immunity, and reduce fatigue. Forty-five percent believed that dancing increased the need for supplementation, whilst 30% recognized that there were risks associated with DSs.
The most frequently consumed DSs were vitamin C (60%), multivitamins (67%), and caffeine (72%). A smaller group of participants declared the use of whey protein (21%) or creatine (14%). Supplements were mainly obtained from pharmacies, supermarkets, and health-food stores. Dancers recognized their lack of knowledge in DSs use and relied on peer recommendations instead of sound evidence-based advice from acknowledged nutrition or health care professionals.
The authors concluded that this study demonstrates that DSs use is internationally prevalent amongst dancers. Continued efforts are warranted with regard to information dissemination.
Finally, a third study investigated use of DSs in patients in Japan. This survey was completed by 2732 people, including 599 admitted patients, 1154 ambulatory patients, and 979 healthy subjects who attended a seminar about DSs. At the time of the questionnaire, 20.4% of admitted patients, 39.1% of ambulatory patients, and 30.7% of healthy subjects were using DSs, which including vitamin/mineral supplements, herbal extracts, its ingredients, or food for specified health uses.
The primary purpose for use in all groups was health maintenance, whereas 3.7% of healthy subjects, 10.0% of ambulatory patients, and 13.2% of admitted patients used DSs to treat diseases. In addition, 17.7% of admitted patients and 36.8% of ambulatory patients were using DSs concomitantly with their medications. However, among both admitted patients and ambulatory patients, almost 70% did not mention DSs use to their physicians. Overall, 3.3% of all subjects realized adverse effects associated with DSs.
The authors concluded that communication between patients and physicians is important to avoid health problems associated with the use of DSs.
There is little doubt, DSs are popular with all sorts of populations and have grown into a multi billion dollar industry. There is also no doubt that the use of only very few DSs are evidence-based (and if so, in only relatively rare situations). And there can be no doubt that many DSs can do harm. What follows is simple: for the vast majority of DSs the benefits do not demonstrably out-weigh the risks.
If that is true, we have to ask ourselves: Why are they so popular?
The answer, I think, is because of the very phenomenon I am constantly trying to fight on this blog – IRRESPONSIBLE CHARLATANS PULLING WOOL OVER CONSUMERS EYES.
Getting good and experienced lecturers for courses is not easy. Having someone who has done more research than most working in the field and who is internationally known, might therefore be a thrill for students and an image-boosting experience of colleges. In the true Christmas spirit, I am today making the offer of being of assistance to the many struggling educational institutions of alternative medicine .
A few days ago, I tweeted about my willingness to give free lectures to homeopathic colleges (so far without response). Having thought about it a bit, I would now like to extend this offer. I would be happy to give a free lecture to the students of any educational institution of alternative medicine. I suggest to
- do a general lecture on the clinical evidence of the 4 major types of alternative medicine (acupuncture, chiropractic, herbal medicine, homeopathy) or
- give a more specific lecture with in-depth analyses of any given alternative therapy.
I imagine that most of the institutions in question might be a bit anxious about such an idea, but there is no need to worry: I guarantee that everything I say will be strictly and transparently evidence-based. I will disclose my sources and am willing to make my presentation available to students so that they can read up the finer details about the evidence later at home. In other words, I will do my very best to only transmit the truth about the subject at hand.
Nobody wants to hire a lecturer without having at least a rough outline of what he will be talking about – fair enough! Here I present a short summary of the lecture as I envisage it:
- I will start by providing a background about myself, my qualifications and my experience in researching and lecturing on the matter at hand.
- This will be followed by a background on the therapies in question, their history, current use etc.
- Next I would elaborate on the main assumptions of the therapies in question and on their biological plausibility.
- This will be followed by a review of the claims made for the therapies in question.
- The main section of my lecture would be to review the clinical evidence regarding the efficacy of therapies in question. In doing this, I will not cherry-pick my evidence but rely, whenever possible, on authoritative systematic reviews, preferably those from the Cochrane Collaboration.
- This, of course, needs to be supplemented by a review of safety issues.
- If wanted, I could also say a few words about the importance of the placebo effect.
- I also suggest to discuss some of the most pertinent ethical issues.
- Finally, I would hope to arrive at a few clear conclusions.
You see, all is entirely up to scratch!
Perhaps you have some doubts about my abilities to lecture? I can assure you, I have done this sort of thing all my life, I have been a professor at three different universities, and I will probably manage a lecture to your students.
A final issue might be the costs involved. As I said, I would charge neither for the preparation (this can take several days depending on the exact topic), nor for the lecture itself. All I would hope for is that you refund my travel (and, if necessary over-night) expenses. And please note: this is time-limited: approaches will be accepted until 1 January 2015 for lectures any time during 2015.
I can assure you, this is a generous offer that you ought to consider seriously – unless, of course, you do not want your students to learn the truth!
(In which case, one would need to wonder why not)
Acupuncture seems to be as popular as never before – many conventional pain clinics now employ acupuncturists, for instance. It is probably true to say that acupuncture is one of the best-known types of all alternative therapies. Yet, experts are still divided in their views about this treatment – some proclaim that acupuncture is the best thing since sliced bread, while others insist that it is no more than a theatrical placebo. Consumers, I imagine, are often left helpless in the middle of these debates. Here are 7 important bits of factual information that might help you make up your mind, in case you are tempted to try acupuncture.
- Acupuncture is ancient; some enthusiast thus claim that it has ‘stood the test of time’, i. e. that its long history proves its efficacy and safety beyond reasonable doubt and certainly more conclusively than any scientific test. Whenever you hear such arguments, remind yourself that the ‘argumentum ad traditionem’ is nothing but a classic fallacy. A long history of usage proves very little – think of how long blood letting was used, even though it killed millions.
- We often think of acupuncture as being one single treatment, but there are many different forms of this therapy. According to believers in acupuncture, acupuncture points can be stimulated not just by inserting needles (the most common way) but also with heat, electrical currents, ultrasound, pressure, etc. Then there is body acupuncture, ear acupuncture and even tongue acupuncture. Finally, some clinicians employ the traditional Chinese approach based on the assumption that two life forces are out of balance and need to be re-balanced, while so-called ‘Western’ acupuncturists adhere to the concepts of conventional medicine and claim that acupuncture works via scientifically explainable mechanisms that are unrelated to ancient Chinese philosophies.
- Traditional Chinese acupuncturists have not normally studied medicine and base their practice on the Taoist philosophy of the balance between yin and yang which has no basis in science. This explains why acupuncture is seen by traditional acupuncturists as a ‘cure all’ . In contrast, medical acupuncturists tend to cite neurophysiological explanations as to how acupuncture might work. However, it is important to note that, even though they may appear plausible, these explanations are currently just theories and constitute no proof for the validity of acupuncture as a medical intervention.
- The therapeutic claims made for acupuncture are legion. According to the traditional view, acupuncture is useful for virtually every condition affecting mankind; according to the more modern view, it is effective for a relatively small range of conditions only. On closer examination, the vast majority of these claims can be disclosed to be based on either no or very flimsy evidence. Once we examine the data from reliable clinical trials (today several thousand studies of acupuncture are available – see below), we realise that acupuncture is associated with a powerful placebo effect, and that it works better than a placebo only for very few (some say for no) conditions.
- The interpretation of the trial evidence is far from straight forward: most of the clinical trials of acupuncture originate from China, and several investigations have shown that very close to 100% of them are positive. This means that the results of these studies have to be taken with more than a small pinch of salt. In order to control for patient-expectations, clinical trials can be done with sham needles which do not penetrate the skin but collapse like miniature stage-daggers. This method does, however, not control for acupuncturists’ expectations; blinding of the therapists is difficult and therefore truly double (patient and therapist)-blind trials of acupuncture do hardly exist. This means that even the most rigorous studies of acupuncture are usually burdened with residual bias.
- Few acupuncturists warn their patients of possible adverse effects; this may be because the side-effects of acupuncture (they occur in about 10% of all patients) are mostly mild. However, it is important to know that very serious complications of acupuncture are on record as well: acupuncture needles can injure vital organs like the lungs or the heart, and they can introduce infections into the body, e. g. hepatitis. About 100 fatalities after acupuncture have been reported in the medical literature – a figure which, due to lack of a monitoring system, may disclose just the tip of an iceberg.
- Given that, for the vast majority of conditions, there is no good evidence that acupuncture works beyond a placebo response, and that acupuncture is associated with finite risks, it seems to follow that, in most situations, the risk/benefit balance for acupuncture fails to be convincingly positive.
While the previous post was about seeing a traditional herbalist (who prescribe their own herbal mixtures, tailor-made for each individual patient), this post provides essential information for those consumers who are tempted to take a commercially available herbal remedy available in pharmacies, health food shops, over the Internet etc. These remedies are usually bought by consumers and then be self-administered, or (less frequently) they might be prescribed/recommended/sold by a clinician such as a doctor, naturopath, chiropractor etc. Typically, they contain just one (or relatively few) herbal extracts and are used under similar assumptions as conventional medicines: one (hopefully well-tested) remedy is employed for treating a defined condition, diagnosed according to validated and generally accepted criteria (for instance, St John’s Wort for depression or Devil’s claw for back pain). This approach is sometimes referred to as ‘rational phytotherapy’ – it is certainly more rational than the traditional herbalism referred to in my previous post. The manufacture, promotion and sale of commercial herbal remedies (in many countries marketed as ‘dietary supplements’) has grown into a multi-billion dollar industry.
Here are a few essentials you ought to know before you decide to take such an herbal remedy:
- Many people claim that herbal medicine is effective because many of our modern drugs are based on plants. The latter part of this claim is true, of course, but this does not necessarily mean that herbal remedies are effective. The drugs derived from plants contain one single, well-defined, extensively researched molecule (by definition, this makes them conventional drugs and not herbal remedies), while herbal remedies are based on entire (parts of) plants; thus they contain many pharmacologically active molecules. This often means that it is difficult or impossible to tell what dose of which ingredient is being administered and what pharmacological actions can be expected.
- Even though national regulations differ greatly, herbal remedies generally do not have to be supported by evidence for efficacy in order to be legally available. This means that a given remedy might or might not have been tested in clinical trials to determine whether it works for the condition advertised. In fact, only very few (less than 30, I estimate) herbal remedies are supported by sound evidence for efficacy; thousands do not meet this criterion.
- The extremely wide-spread notion that herbal remedies are by definition natural and therefore safe is nothing but a promotional myth. Plants contain many chemicals which can have pharmacological activity. This means they might be therapeutic, but it also means that they might be toxic (traditionally the most powerful poisons originated from the plant kingdom). If anyone uses the ‘natural = safe fallacy’ remind him/her of hemlock, poison ivy etc.
- In addition to potential toxicity of an herbal ingredient, there are other important safety issues to be considered. Most importantly, herbal remedies can interact with prescribed medicines. For instance, St John’s Wort (one of the best-studied herbal remedies in this respect) powerfully interacts with about 50% of all prescription drugs – in fact, it lowers their level in the blood which means that a patient on anti-coagulants would lose her anti-coagulant protection and might suffer from a (potentially fatal) blood clot.
- In many countries, including the US, the regulation of herbal remedies is so lax, that there is no guarantee that an herbal remedy which is being legally sold is safe. The regulators are only allowed to intervene once there are reports of adverse effects. This means that the burden of proof of safety is effectively reversed which obviously exposes consumers to incalculable risks.
- The quality of the herbal product is equally poorly regulated in most countries. A plethora of investigations in the US, for instance, has shown that the dose of the herbal ingredient printed on the label of a commercial product can range virtually from 0 – 100%. Similarly there is little safe-guard that the ingredients listed on the label correspond to the ones in the preparation. This means that it is worth purchasing not just well-researched herbal remedies but also those marketed by high quality manufacturers via respectable outlets.
- Any regulation of herbal remedies, even the European one that is often praised as protecting consumers adequately, is null and void once consumers go on the Internet and purchase their herbal remedies from one of the many dubious sources found there in truly alarming profusion. Bogus claims, inferior quality and even outright dangerous products abound, and it is often impossible to tell the acceptable from the fraudulent product.
Here I am not writing about herbal medicine in general – parts of which are supported by some encouraging evidence (I will therefore post more than one ‘seven things to remember…’ article on this subject) – here I am writing about the risks and benefits of consulting a traditional herbal practitioner. Herbalists come in numerous guises depending what tradition they belong to: Chinese herbalist, traditional European herbalist, Ayurvedic practitioner, Kampo practitioner etc. If you consult such a therapist, you should be aware of the following issues.
- Worldwide, the treatment by traditional herbal practitioners is by far the most common form of herbal medicine; it is more common than to use specific, well-tested herbs to treat specific conventionally diagnosed conditions (an approach that might best be called ‘rational phytotherapy’).
- Herbalists often use their very own diagnostic methods (think, for instance, of ‘tongue and pulse diagnoses’ used by Chinese herbalists) and reject (or are untrained to use) conventional diagnostic methods. The traditional diagnostic techniques of herbalists have either not been validated at all or they have been tested and found to be not valid.
- Herbalists usually do not recognise conventional disease categories. Instead they arrive at a diagnosis according to their specific philosophy which has no grounding in reality (for instance, energy imbalance in traditional Chinese herbalism).
- Herbalists individualise their treatments, meaning that 10 patients suffering from depression, for instance, might receive 10 different, tailor-made prescriptions according to their individual characteristics (and none of the 10 patients might receive St John’s Wort, the only herbal remedy that actually is proven to work for depression).
- Typically, such prescriptions contain not one herbal ingredient, but are mixtures of many – up to 10 or 20 – herbs or herbal extracts.
- Even though the efficacy of the individualised herbal approach can, of course, be tested in rigorous trials, and even though about a dozen such studies are available today, there is currently no good evidence to show that it is effective.
- The risk of harm through these individualised herbal mixtures can be considerable: the more ingredients, the higher the likelihood that one of them has toxic effects or that one interacts with a prescription medicine. Essentially, this means that there is no good evidence that individualised herbal treatments as used by so many herbal practitioners across the globe generates more good than harm.
Some of the recent comments on this blog have been rather emotional, a few even irrational, and several were, I am afraid, outright insulting (I usually omit to post the worst excesses). Moreover, I could not avoid the impression that some commentators have little understanding of what the aim of this blog really is. I tried to point this out in the very first paragraph of my very first post:
Why another blog offering critical analyses of the weird and wonderful stuff that is going on in the world of alternative medicine? The answer is simple: compared to the plethora of uncritical misinformation on this topic, the few blogs that do try to convey more reflected, sceptical views are much needed; and the more we have of them, the better.
My foremost aim with his blog is to inform consumers through critical analysis and, in this way, I hope to prevent harm from patients in the realm of alternative medicine. What follows, are a few simple yet important points about this blog which I try to spell out here as clearly as I can:
- I am not normally commenting on issues related to conventional medicine – not because I feel there is nothing to criticise in mainstream medicine, but because my expertise has long been in alternative medicine. So commentators might as well forget about arguments like “more people die because of drugs than alternative treatments”; they are firstly fallacious and secondly not relevant to this blog.
- I have researched alternative medicine for many years (~ 40 clinical studies, > 300 systematic reviews etc.) and my readers can be confident that I know what I am talking about. Thus comments like ‘he does not know anything about the subject’ are usually not well placed and just show the ignorance of those who post them.
- I am not in the pocket of anyone. I do not receive payments for doing this blog, nor did I, as an academic, receive any financial or other inducements for researching alternative medicine (on the contrary, I have often been given to understand that my life could be made much easier, if I adopted a more promotional stance towards my alternative medicine). I also do not belong to any organisation that is financed by BIG PHARMA or similar power houses. So my critics might as well abandon their conspiracy theories and focus on a more promising avenue of criticism.
- My allegiance is not with any interest group in (or outside) the field of alternative medicine. For instance, I do not see it as my job to help chiropractors, homeopaths etc. getting their act together. My task here is to point out the deficits in chiropractic (or any other area of alternative medicine) so that consumers are better protected. (I should think, however, that this also creates pressure on professions to become more evidence-based – but I see this as a mere welcome side-effect.)
- If some commentators seem to find my arguments alarmist or see it as venomous scare-mongering, I suggest they re-examine their own position and learn to think a little more (self-) critically. I furthermore suggest that, instead of claiming such nonsense, they point out where they think I have gone wrong and provide evidence for their views.
- Some people seem convinced that I have an axe to grind, that I have been personally injured by some alternative practitioner, or had some other unpleasant or traumatic experience. To those who think so, I have to say very clearly that none of this has ever happened. I recommend they inform themselves of the nature of critical analysis and its benefits.
- This is a blog, not a scientific journal. I try to reach as many lay people as I can and therefore I tend to use simple language and sometimes aim to be entertaining. Those who feel that this renders my blog more journalistic than scientific are probably correct. If they want science, I recommend they look for my scientific articles in the medical literature; I can assure them that they will find plenty.
- I very much invite an open and out-spoken debate. But ad hominem attacks are usually highly counterproductive – they only demonstrate that the author has no rational arguments left, or had none in the first place. Authors of insults also risks being banned from this blog.
- Finally, I fear that some readers of my blog might sometimes get confused in the arguments and counter-arguments, and end up uncertain which side is right and which is wrong. To those who have this problem, I recommend a simple method for deciding where the truth is usually more likely to be found: ask yourself who might be merely defending his/her self-interest and who might be free of such conflicts of interest and thus more objective. For example, in my endless disputes with chiropractors, one could well ask: do the chiropractors have an interest in defending their livelihood, and what interest do I have in questioning whether chiropractors do generate more good than harm?
In many countries, consumers seem to be fond of consulting chiropractors – mostly for back pain, but also for other conditions. I therefore think it is might be a good and productive idea to give anyone who is tempted to see a chiropractor some simple, easy to follow advice. Here we go:
- Ask your chiropractor what he/she thinks about the chiropractic concept of subluxation. This is the chiropractors’ term (real doctors use the word too but understand something entirely different by it) for an imagined problem with your spine. Once they have diagnosed you to suffer from subluxation, they will persuade you that it needs correcting which is done by spinal manipulation which they tend to call ‘adjustments’. There are several important issues here: firstly subluxations do not exist outside the fantasy world of chiropractic; secondly chiropractors who believe in subluxation would diagnose subluxation in about 100% of the population – also in individuals who are completely healthy. My advice is to return straight back home as soon as the chiropractor admits he believes in the mystical concept of subluxation.
- Ask your chiropractor what he/she thinks of ‘maintenance care’. This is the term many chiropractors use for indefinite treatments which do little more than transfer lots of cash from your account to that of your chiropractor. There is no good evidence to show that maintenance care does, as chiropractors claim, prevent healthy individuals from falling ill. So, unless you have the irresistible urge to burn money, don’t fall for this nonsense. You should ask your chiropractor how long and frequent your treatment will be, what it will cost, and then ask yourself whether it is worth it.
- Run a mile, if the chiropractor wants to manipulate your neck (which most will do regardless of whether you have neck-pain, some even without informed consent). Neck manipulation is associated with very serious complications; they are usually caused by an injury to an artery that supplies parts of your brain. This can cause a stroke and even death. Several hundred such cases have been documented in the medical literature – but the true figure is almost certainly much larger (there is still no system in place to monitor such events).
- Run even faster, if the chiropractor wants to treat your children for common paediatric conditions. Many chiropractors believe that their manipulations are effective for a wide range of health problems that kids frequently suffer from. However, there is not a jot of evidence that these claims are true.
- Be aware that about 50% of all patients having chiropractic treatments will suffer from side effects like pain and stiffness. These symptoms usually last for 2-3 days and can be severe enough to impede your quality of life. Ask yourself whether the risk is outweighed by the benefit of chiropractic.
- Remember that there is no good evidence that chiropractors can treat any condition effectively other than lower back pain (and even for that condition the evidence is far from strong). Many chiropractors claim to be able to treat a plethora of non-spinal conditions like asthma, ear infection, gastrointestinal complaints, autism etc. etc. There is no good evidence that these claims are correct.
- Distrust the advice given by many chiropractors regarding prescribed medications, vaccinations or surgery. Chiropractic has a long history of warning their patients against all sorts of conventional treatments. Depending on the clinical situation, following such advice can cause very serious harm.
I am minded to write similar posts for all major alternative therapies (this will not make me more popular with alternative therapists, but I don’t mind all that much) – provided, of course, that my readers find this sort of article useful. So, please do give me some feedback.
If you have diabetes, chances are that you need life-long treatment. Before effective anti-diabetic medications became available, diabetes amounted to a death sentence. Fortunately, these times are long gone.
…unless, of course, you decide to listen to the promises of alternative practitioners many of whom offer a cure for diabetes. Here is just one website of hundreds that does just that. The following is an abbreviated quote where I have changed nothing, not even the numerous spelling mistakes:
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.
Alternative medicine like ayurveda is a best to cure diabetes naturally.
A serious disorder of the glands,of pancreas to be exact,is diabetes,or madhumeha as described in ayurveda.It is one of the most insidious disorders of the metabolism and,if left undiagnosed or untreated,it may lead to rapid emaciation and ultimately death…
Ayurveda medicines to cure diabetes
In ayurveda the following medicines have been recommended for this disease
Shiljita ————————–240 mg
Nyagrodadhi churna ———3 gm
These should be given twice after meals with decoction of arni.
Vasantakusumakara rasa —120 mg
Shudha Shilajit ————–240 mg
Nag Bhasma —————–120 mg
Haldi ————————–500 mg
Amlaki Churna ————-500 mg
Twice daily with powder of rose-apple stones.Twice daily with honey.
Chadraprabha Vati ——– 500 mg
Mudra the alternative treatment to cure diabetes naturally
Mudra is a non medical and no cost treatment to cure diabetes.You can perform mudras at any time or any position.It is an effective way of treatment you can get better result if you practice it regularly .
It goes without saying that none of these treatments would cure diabetes. A Cochrane review concluded that there is insufficient evidence at present to recommend the use of these interventions in routine clinical practice. It also goes without saying that not many patients would fall for the nonsense proclaimed on this or so many other websites. But even just one single patient dying because of some charlatan promising a cure for life-threatening diseases is one patient too many.
Here and elsewhere, I have repeatedly written about the many things that can go wrong with acupuncture. This invariably annoys acupuncture fans who usually counter by accusing me of being alarmist. Despite their opposition, I continue to think it is important to regularly point out that acupuncture – contrary to what many acupuncturists would tell us – can result in serious injury. I will therefore carry on reporting new evidence about the harm caused by acupuncture. Here is a very brief review of new (2014) articles on this important topic.
A recent study found that the incidence of any adverse events per patient was 42.4% with traditional acupuncture, 40.7% with minimal acupuncture and 16.7% with non-invasive sham acupuncture. These figures are much higher than those around 10% previously reported.
Other authors described the case of a broken off acupuncture needle in a patient’s abdomen. A very long needle was used which happily is unusual in routine practice.
Pneumothorax has been often noted as a complication of acupuncture – it is by far the most frequently reported serious complication caused by acupuncture; well over 100 instances have been described in the medical literature which, of course, reflects only the tip of an iceberg – new cases are being reported almost on a monthly basis.
Cardiac tamponade is even more dangerous but fortunately also much rarer. A case of life-threatening cardiac tamponade due to penetration of an acupuncture needle directly into the right ventricle was recently published. Cardiac tamponade can happen when the patient is unfortunate enough to have a sternal foramen, an congenital abnormality that is not normally detected by simple inspection or palpation. An investigation found that the frequency of a sternal foramen is approximately 10.5%. The authors concluded that sternal acupuncture should be planned in the region of corpus-previous CT should be done to rule out this variation. Furthermore, we strongly recommend the acupuncture technique which prescribes a safe superficial-oblique approach to the sternum.
A review from Egypt noted that acupuncture presented a significant risks for acquiring hepatitis C infections.
Other types of infections can also be transmitted by acupuncture needles, if the therapist fails to adhere to proper procedures of sterility. One report described the diagnosis, treatment and >1 year follow-up of 30 patients presenting with acupuncture-induced primary inoculation tuberculosis.
Similarly, Chinese authors reported the case of a 54-year-old woman who presented with progressive low back pain and fever. She underwent surgical decompression, with an immediate improvement of her pain. A culture of the epidural abscess grew Serratia marcescens. One year postoperatively, magnetic resonance imaging revealed the almost complete eradication of the abscess. This case is the first case of Serratia marcescens-associated spinal epidural abscess formation secondary to acupuncture.
Other authors reported a rare case of isolated unilateral hypoglossal nerve injury following ipsilateral acupuncture for migraines in a 53-year-old lady.
Finally, Greek authors published a case of severe rhabdomyolysis and acute kidney injury after acupuncture sessions. Rhabdomyolysis is a rare condition that can be caused by muscle injury and presents with muscle weakness and pain. It is characterized by myoglobinuria which, in turn, may cause acute kidney injury.
I can hear the world of acupuncture arguing that all of these events are extreme rarities and that conventional treatments are much more dangerous. This may well be true but it also ignores the following facts:
- The frequency of such events is essentially unknown. Contrary to conventional medicine, alternative medicine has no functioning systems to monitor adverse events. Therefore the true incidence figures of acupuncture-related complications are anyone’s guess.
- Most conventional treatments in common use are backed up by good evidence for efficacy and therefore demonstrably do more good than harm, even if they regularly cause adverse effects. This is not the case for acupuncture. In the absence of solid evidence for efficacy, even relatively rare or minor adverse effects would mean that the risk/benefit profile of acupuncture is not positive.
For these reasons, it is an ethical imperative, I think, to keep a keen eye on the harm caused by acupuncture and to inform the public about the fact that it is undeniably not free of risks.
‘Healing, hype or harm? A critical analysis of complementary or alternative medicine’ is the title of a book that I edited and that was published in 2008. Its publication date coincided with that of ‘Trick or Treatment?’ and therefore the former was almost completely over-shadowed by the latter. Consequently few people know about it. This is a shame, I think, and this post is dedicated to encouraging my readers to have a look at ‘Healing, hype or harm?’
One reviewer commented on Amazon about this book as follows: Vital and informative text that should be read by everyone alongside Ben Goldacre’s ‘Bad Science’ and Singh and Ernt’s ‘Trick or Treatment’. Everyone should be able to made informed choices about the treatments that are peddled to the desperate and gullible. As Tim Minchin famously said ‘What do you call Alternative Medicine that has been proved to work? . . . Medicine!’
This is high praise indeed! But I should not omit the fact that others have commented that they were appalled by our book and found it “disappointing and unsettling”. This does not surprise me in the least; after all, alternative medicine has always been a divisive subject.
The book was written by a total of 17 authors and covers many important aspects of alternative medicine. Some of its most famous contributors are Michael Baum, Gustav Born, David Colquhoun, James Randi and Nick Ross. Some of the most important subjects include:
As already mentioned, our book is already 6 years old; however, this does not mean that it is now out-dated. The subject areas were chosen such that it will be timely for a long time to come. Nor does this book reflect one single point of view; as it was written by over a dozen different experts with vastly different backgrounds, it offers an entire spectrum of views and attitudes. It is, in a word, a book that stimulates critical thinking and thoughtful analysis.
I sincerely think you should have a look at it… and, in case you think I am hoping to maximise my income by telling you all this: all the revenues from this book go to charity.
