risk

1 2 3 5

Few subjects lead to such heated debate as the risk of stroke after chiropractic manipulations (if you think this is an exaggeration, look at the comment sections of previous posts on this subject). Almost invariably, one comes to the conclusion that more evidence would be helpful for arriving at firmer conclusions. Before this background, this new publication by researchers (mostly chiropractors) from the US ‘Dartmouth Institute for Health Policy & Clinical Practice’ is noteworthy.

The purpose of this study was to quantify the risk of stroke after chiropractic spinal manipulation, as compared to evaluation by a primary care physician, for Medicare beneficiaries aged 66 to 99 years with neck pain.

The researchers conducted a retrospective cohort analysis of a 100% sample of annualized Medicare claims data on 1 157 475 beneficiaries aged 66 to 99 years with an office visit to either a chiropractor or to a primary care physician for neck pain. They compared hazard of vertebrobasilar stroke and any stroke at 7 and 30 days after office visit using a Cox proportional hazards model. We used direct adjusted survival curves to estimate cumulative probability of stroke up to 30 days for the 2 cohorts.

The findings indicate that the proportion of subjects with a stroke of any type in the chiropractic cohort was 1.2 per 1000 at 7 days and 5.1 per 1000 at 30 days. In the primary care cohort, the proportion of subjects with a stroke of any type was 1.4 per 1000 at 7 days and 2.8 per 1000 at 30 days. In the chiropractic cohort, the adjusted risk of stroke was significantly lower at 7 days as compared to the primary care cohort (hazard ratio, 0.39; 95% confidence interval, 0.33-0.45), but at 30 days, a slight elevation in risk was observed for the chiropractic cohort (hazard ratio, 1.10; 95% confidence interval, 1.01-1.19).

The authors conclude that, among Medicare B beneficiaries aged 66 to 99 years with neck pain, incidence of vertebrobasilar stroke was extremely low. Small differences in risk between patients who saw a chiropractor and those who saw a primary care physician are probably not clinically significant.

I do, of course, applaud any new evidence on this rather ‘hot’ topic – but is it just me, or are the above conclusions a bit odd? Five strokes per 1000 patients is definitely not “extremely low” in my book; and furthermore I do wonder whether all experts would agree that a doubling of risk at 30 days in the chiropractic cohort is “probably not clinically significant” – particularly, if we consider that chiropractic spinal manipulation has so very little proven benefit.

My message to (chiropractic) researchers is simple: PLEASE REMEMBER THAT SCIENCE IS NOT A TOOL FOR CONFIRMING BUT FOR TESTING HYPOTHESES.

On 1/12/2014 I published a post in which I offered to give lectures to students of alternative medicine:

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 did not think that this would create much interest – and I was right: only the ANGLO-EUROPEAN COLLEGE OF CHIROPRACTIC has so far hoisted me on my own petard and, after some discussion (see comment section of the original post) hosted me for a lecture. Several people seem keen on knowing how this went; so here is a brief report.

I was received, on 14/1/2015, with the utmost kindness by my host David Newell. We has a coffee and a chat and then it was time to start the lecture. The hall was packed with ~150 students and the same number was listening in a second lecture hall to which my talk was being transmitted.

We had agreed on the title CHIROPRACTIC: FALLACIES AND FACTS. So, after telling the audience about my professional background, I elaborated on 7 fallacies:

  1. Appeal to tradition
  2. Appeal to authority
  3. Appeal to popularity
  4. Subluxation exists
  5. Spinal manipulation is effective
  6. Spinal manipulation is safe
  7. Ad hominem attack

Numbers 3, 5 and 6 were dealt with in more detail than the rest. The organisers had asked me to finish by elaborating on what I perceive as the future challenges of chiropractic; so I did:

  1. Stop happily promoting bogus treatments
  2. Denounce obsolete concepts like ‘subluxation’
  3. Clarify differences between chiros, osteos and physios
  4. Start a culture of critical thinking
  5. Take action against charlatans in your ranks
  6. Stop attacking everyone who voices criticism

I ended by pointing out that the biggest challenge, in my view, was to “demonstrate with rigorous science which chiropractic treatments demonstrably generate more good than harm for which condition”.

We had agreed that my lecture would be followed by half an hour of discussion; this period turned out to be lively and had to be extended to a full hour. Most questions initially came from the tutors rather than the students, and most were polite – I had expected much more aggression.

In his email thanking me for coming to Bournemouth, David Newell wrote about the event: The general feedback from staff and students was one of relief that you possessed only one head, :-). I hope you may have felt the same about us. You came over as someone who had strong views, a fair amount of which we disagreed with, but that presented them in a calm, informative and courteous manner as we did in listening and discussing issues after your talk. I think everyone enjoyed the questions and debate and felt that some of the points you made were indeed fair critique of what the profession may need to do, to secure a more inclusive role in the health care arena.

 
As you may have garnered from your visit here, the AECC is committed to this task as we continue to provide the highest quality of education for the 21st C representatives of such a profession. We believe centrally that it is to our society at large and our communities within which we live and work that we are accountable. It is them that we serve, not ourselves, and we need to do that as best we can, with the best tools we have or can develop and that have as much evidence as we can find or generate. In this aim, your talk was important in shining a more ‘up close and personal’ torchlight on our profession and the tasks ahead whilst also providing us with a chance to debate the veracity or otherwise of yours and ours differing positions on interpretation of the evidence.

My own impression of the day is that some of my messages were not really understood, that some of the questions, including some from the tutors, seemed like coming from a different planet, and that people were more out to teach me than to learn from my talk. One overall impression that I took home from that day is that, even in this college which prides itself of being open to scientific evidence and unimpressed by chiropractic fundamentalism, students are strangely different from other health care professionals. The most tangible aspect of this is the openly hostile attitude against drug therapies voiced during the discussion by some students.

The question I always ask myself after having invested a lot of time in preparing and delivering a lecture is: WAS IT WORTH IT? In the case of this lecture, I think the answer is YES. With 300 students present, I am fairly confident that I did manage to stimulate a tiny bit of critical thinking in a tiny percentage of them. The chiropractic profession needs this badly!

 

I know, it’s not really original to come up with the 10000th article on “10 things…” – but you will have to forgive me, I read so many of these articles over the holiday period that I can’t help but jump on the already over-crowded bandwagon and compose yet another one.

So, here are 10 things which could, if implemented, bring considerable improvement in 2015 to my field of inquiry, alternative medicine.

  1. Consumers need to get better at acting as bull shit (BS) detectors. Let’s face it, much of what we read or hear about this subject is utter BS. Yet consumers frequently lap up even the worst drivel like it were some source of deep wisdom. They could save themselves so much money, if they learnt to be just a little bit more critical.
  2. Dr Oz should focus on being a heart surgeon. His TV show has been demonstrated far too often to be promoting dangerous quackery. Yet as a heart surgeon, he actually might do some good.
  3. Journalists ought to remember that they have a job that extends well beyond their ambition to sell copy. They have a responsibility to inform the public truthfully and responsibly.
  4. Book publishers should abstain from churning out book after book that does little else but mislead the public about alternative medicine in a way that all to often is dangerous to the readers’ health. The world does not need the 1000th book repeating nonsense on detox, wellness etc.!
  5. Alternative practitioners must realise that claiming that therapy x cures condition y is not just slightly over-optimistic (or based on ‘years of experience’); if the claim is not based on sound evidence, it is what most people would call an outright lie.
  6. Proponents of alternative medicine should learn that it is neither fair nor productive to fiercely attack everyone personally who disagrees with their enthusiasm for this or that form of alternative medicine. In fact, it merely highlights the acute lack of rational arguments.
  7. Researchers of alternative medicine have to remember how important it is to think critically – an uncritical scientist is at best a contradiction in terms and at worst a pseudo-scientist who is likely to cause harm.
  8. Authorities should amass the courage, the political power and the financial means of going after those charlatans who ruthlessly exploit the public by making a fast and easy buck on the gullibility of consumers. Only if there is the likelihood of hefty fines will we see a meaningful decrease in the current epidemic of alternative health fraud.
  9. Politicians should realise that alternative medicine is not just a trivial subject with which one might win votes, if one issues platitudes to please the majority; alternative medicine is used by so many people that it has become an important public health issue.
  10. Prince Charles need to learn how to control himself and abstain from meddling in health politics by using every conceivable occasion to promote what he thinks is ‘integrated medicine’ but which, in fact, can easily be disclosed to be quackery.

As you see, my list almost instantly turned into a wish-list, and the big questions that follow from it are:

  1. How could we increase the likelihood of these wishes to come true?
  2. And would there be anything left of alternative medicine, if all of these wishes miraculously became true in 2015?

I do not pretend to have the answers, but I do feel strongly that a healthy dose of critical thinking in all levels of education – from kindergartens to schools, from colleges to universities etc. – would be a good and necessary starting point.

I know, my list is not just a wish list, it also is a wishful thinking list. It would be hopelessly naïve to assume that major advances will be made in 2015. I am realistic, sometimes even quite pessimistic, about progress in alternative medicine. But this does not mean that I or anyone else should just give up. 2015 will be a year where at least one thing is certain: you will see me continuing me my fight for reason, critical analysis, rational debate and good evidence – and that’s a promise!

Few subjects make chiropractors more uneasy than a discussion of the safety of their spinal manipulations. Many chiropractors flatly deny that there are any risks at all. However, the evidence seems to tell a different story.

The purpose of a new review was to summarise the literature for cases of adverse events in infants and children treated by chiropractors or other manual therapists, identifying treatment type and if a preexisting pathology was present. English language, peer-reviewed journals and non-peer-reviewed case reports discussing adverse events (ranging from minor to serious) were systematically searched from inception of the relevant searchable bibliographic databases through March 2014. Articles not referring to infants or children were excluded.

Thirty-one articles met the selection criteria. A total of 12 articles reporting 15 serious adverse events were found. Three deaths occurred under the care of various providers (1 physical therapist, 1 unknown practitioner, and 1 craniosacral therapist) and 12 serious injuries were reported (7 chiropractors/doctors of chiropractic, 1 medical practitioner, 1 osteopath, 2 physical therapists, and 1 unknown practitioner). High-velocity, extension, and rotational spinal manipulation was reported in most cases, with 1 case involving forcibly applied craniosacral dural tension and another involving use of an adjusting instrument. Underlying preexisting pathology was identified in a majority of the cases.

The authors concluded that published cases of serious adverse events in infants and children receiving chiropractic, osteopathic, physiotherapy, or manual medical therapy are rare. The 3 deaths that have been reported were associated with various manual therapists; however, no deaths associated with chiropractic care were found in the literature to date. Because underlying preexisting pathology was associated in a majority of reported cases, performing a thorough history and examination to exclude anatomical or neurologic anomalies before applying any manual therapy may further reduce adverse events across all manual therapy professions.

This review is a valuable addition to our knowledge about the risks of spinal manipulations. My own review summarised 26 deaths after chiropractic manipulations. In several of these instances, the age of the patient had not been reported. Therefore the above conclusion (no deaths associated with chiropractic) seems a little odd.

The following text is a shortened version of the discussion of my review which, I think, addresses most of the pertinent issues.

 numerous deaths have been associated with chiropractic. Usually high-velocity, short-lever thrusts of the upper spine with rotation are implicated. They are believed to cause vertebral arterial dissection in predisposed individuals which, in turn, can lead to a chain of events including stroke and death. Many chiropractors claim that, because arterial dissection can also occur spontaneously, causality between the chiropractic intervention and arterial dissection is not proven. However, when carefully evaluating the known facts, one does arrive at the conclusion that causality is at least likely. Even if it were merely a remote possibility, the precautionary principle in healthcare would mean that neck manipulations should be considered unsafe until proven otherwise. Moreover, there is no good evidence for assuming that neck manipulation is an effective therapy for any medical condition. Thus, the risk-benefit balance for chiropractic neck manipulation fails to be positive.

Reliable estimates of the frequency of vascular accidents are prevented by the fact that underreporting is known to be substantial. In a survey of UK neurologists, for instance, under-reporting of serious complications was 100%. Those cases which are published often turn out to be incomplete. Of 40 case reports of serious adverse effects associated with spinal manipulation, nine failed to provide any information about the clinical outcome. Incomplete reporting of outcomes might therefore further increase the true number of fatalities.

This review is focussed on deaths after chiropractic, yet neck manipulations are, of course, used by other healthcare professionals as well. The reason for this focus is simple: chiropractors are more frequently associated with serious manipulation-related adverse effects than osteopaths, physiotherapists, doctors or other professionals. Of the 40 cases of serious adverse effects mentioned above, 28 can be traced back to a chiropractor and none to a osteopath. A review of complications after spinal manipulations by any type of healthcare professional included three deaths related to osteopaths, nine to medical practitioners, none to a physiotherapist, one to a naturopath and 17 to chiropractors. This article also summarised a total of 265 vascular accidents of which 142 were linked to chiropractors. Another review of complications after neck manipulations published by 1997 included 177 vascular accidents, 32 of which were fatal. The vast majority of these cases were associated with chiropractic and none with physiotherapy. The most obvious explanation for the dominance of chiropractic is that chiropractors routinely employ high-velocity, short-lever thrusts on the upper spine with a rotational element, while the other healthcare professionals use them much more sparingly.

[REFERENCES FOR THE ABOVE STATEMENTS CAN BE FOUND IN MY REVIEW]

Naturopathy can be defined as ‘an eclectic system of health care that uses elements of complementary and conventional medicine to support and enhance self-healing processes’. This basically means that naturopaths employ treatments based on those therapeutic options that are seen as natural, e. g. herbs, water, exercise, diet, fresh air, heat and cold – but occasionally also acupuncture, homeopathy and manual therapies. If you are tempted to see a naturopath, you might want to consider the following 7 points:

  1. In many countries, naturopathy is not a protected title; this means your naturopaths may have some training but this is not obligatory. Some medical doctors also practice naturopathy, and in some countries there are ‘doctors of naturopathy’ (these practitioners tend to see themselves as primary care physicians but they have not been to medical school).
  2. Naturopathy is steeped in the obsolete concept of vitalism which has been described as the belief that “living organisms are fundamentally different from non-living entities because they contain some non-physical element or are governed by different principles than are inanimate things.”
  3. While there is some evidence to suggest that some of the treatments used by naturopaths are effective for treating some conditions, this is by no means the case for all of the treatments in question.
  4. Naturopathy is implicitly based on the assumption that natural means safe. This notion is clearly wrong and misleading: not all the treatments used by naturopaths are strictly speaking natural, and very few are totally free of risks.
  5. Many naturopaths advise their patients against conventional treatments such as vaccines or antibiotics.
  6. Naturopaths tend to believe they can cure all or most diseases. Consequently many of the therapeutic claims for naturopathy found on the Internet and elsewhere are dangerously over-stated.
  7. The direct risks of naturopathy depend, of course, on the modality used; some of them can be considerable. The indirect risks of naturopathy can be even more serious and are mostly due to naturopathic treatments replacing more effective conventional therapies in cases of severe illness.

THIS POST IS DEDICATED TO HRH, THE PRINCE OF WALES WHO CELEBRATES HIS 66TH BIRTHDAY TODAY AND HAS SUPPORTED HOMEOPATHY ALL HIS LIFE

Like Charles, many people are fond of homeopathy; it is particularly popular in India, Germany, France and parts of South America. With all types of health care, it is important to make therapeutic decisions in the knowledge of the crucial facts. In order to aid evidence-based decision-making, I will summarise a few things you might want to consider before you try homeopathy – either by buying homeopathic remedies over the counter, or by consulting a homeopath.

  1. Homeopathy was invented by Samuel Hahnemann, a charismatic German doctor, about 200 years ago. At the time, our understanding of the laws of nature was woefully incomplete, and therefore Hahnemann’s ideas seemed far less implausible than they actually are. Moreover, the conventional treatments of this period were often more dangerous than the disease they were supposed to cure; consequently homeopathy was repeatedly shown to be better than ‘allopathy’ (a term coined by Hahnemann to insult conventional medicine). Thus Hahnemann’s treatments were an almost instant worldwide success. When, about 100 years later, more and more effective conventional therapies were discovered, homeopathy all but disappeared, only to be re-discovered in developed countries as the baby-boomers started their recent love-affair with alternative medicine.
  2. Many consumers confuse homeopathy with herbal medicine; yet the two are fundamentally different. Herbal medicines are plant extracts with potentially active ingredients. Homeopathic remedies may be based on plants (or any other material as well) but are typically so dilute that they contain absolutely nothing. The most frequently used dilution (homeopaths call them ‘potencies’) is a ‘C30′; a C30-potency has been diluted 30 times at a ratio of 1:100. This means that one drop of the staring material is dissolved in 1 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 drops of diluent – and that equates to one molecule of the original substance per all the molecules of many thousand universes.
  3. Homeopaths know all of this, of course, and they thus claim that their remedies do not work via pharmacological effects but via some ‘energy’ or ‘vital force’. They are convinced that the process of preparing the homeopathic dilutions (they shake the mixtures at each dilution step) transfers some ‘vital energy’ from one to the next dilution. They cite all sorts of fancy theories to explain how this ‘energy transfer’ might come about, however, none of them has ever been accepted by mainstream scientists.
  4. Homeopathic remedies are usually prescribed according to the ‘like cures like’ principle. For instance, if you suffer from runny eyes, a homeopath might prescribe a remedy made of onion, because onion make our eyes water. This and all other basic assumptions of homeopathy contradict the known laws of nature. In other words, we do not just fail to understand how homeopathy works, but we understand that it cannot work unless the known laws of nature are wrong.
  5. The clinical trials of homeopathy are broadly in agreement with these insights from basic science. Today, more than 200 such studies have been published; if we look at the totality of this evidence, we have to conclude that it fails to show that homeopathic remedies are anything other than placebos.
  6. This is, of course, in stark contrast to what many enthusiasts of homeopathy insist upon; they swear by homeopathy and claim that it has helped them (or their pet, aunt, child etc.) repeatedly. Nobody doubts their accounts; in fact, it is indisputable that many patients do get better after taking homeopathic remedies. The best evidence available today clearly shows, however, that this improvement is unrelated to the homeopathic remedy per se. It is the result of an empathetic, compassionate encounter with a homeopath, a placebo-response or other factors which experts often call ‘context effects’.
  7. The wide-spread notion that homeopathy is completely free of risks is not correct. The remedy itself might be harmless (except, of course, for the damage it creates to your finances, and the fact that irrational nonsense about ‘vital energy’ etc. undermines rationality in general) but this does not necessarily apply to the homeopath. Whenever homeopaths advise their patients, as they often do, to forgo effective conventional treatments for a serious condition, they endanger lives. This phenomenon is documented, for instance, in relation to the advice of many homeopaths against immunisations. Any treatment that has no proven benefit, while carrying a finite risk, cannot generate more good than harm.

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.

It has been estimated that 40 – 70% of all cancer patients use some form of alternative medicine; may do so in the hope this might cure their condition. A recent article by Turkish researchers – yet again – highlights how dangerous such behaviour can turn out to be.

The authors report the cases of two middle-aged women suffering from malignant breast masses. The patients experienced serious complications in response to self-prescribed use of alternative medicine practices to treat their condition in lieu of evidence-based medical treatments. In both cases, the use and/or inappropriate application of alternative medical approaches promoted the progression of malignant fungating lesions in the breast. The first patient sought medical assistance upon development of a fungating lesion, 7∼8 cm in diameter and involving 1/3 of the breast, with a palpable mass of 5×6 cm immediately beneath the wound. The second patient sought medical assistance after developing of a wide, bleeding, ulcerous area with patchy necrotic tissue that comprised 2/3 of the breast and had a 10×6 cm palpable mass under the affected area.

The authors argue that the use of some non-evidence-based medical treatments as complementary to evidence-based medical treatments may benefit the patient on an emotional level; however, this strategy should be used with caution, as the non-evidence-based therapies may cause physical harm or even counteract the evidence-based treatment.

Their conclusions: a malignant, fungating wound is a serious complication of advanced breast cancer. It is critical that the public is informed about the potential problems of self-treating wounds such as breast ulcers and masses. Additionally, campaigns are needed to increase awareness of the risks and life-threatening potential of using non-evidence-based medical therapies exclusively.

I have little to add to this; perhaps just a further reminder that the risk extends, of course, to all serious conditions: even a seemingly harmless but ineffective therapy can become positively life-threatening, if it is used as an alternative to an effective treatment. I am sure that some ‘alternativists’ will claim that I am alarmist; but I am also convinced that they are wrong.

Cardiovascular (and most other types of) patients frequently use herbal remedies in addition to their prescribed medicines. Can this behaviour create problems? Many experts think so.

The aim of a new study was to investigate the effect of herbal medicine use on medication adherence of cardiology patients. All patients admitted to the outpatient cardiology clinics, who had been prescribed at least one cardiovascular drug before, were asked to complete a questionnaire. Participants were asked if they have used any herbals during the past 12 months with an expectation of beneficial effect on health. Medication adherence was measured by using the Morisky Scale. High adherence was defined as a Morisky score lower than 2 and a score of 2 or more was seen as low adherence.

A total of 390 patients participated in this study; 29.7% of them had consumed herbals in the past 12 months. The median Morisky score was significantly higher in herbal users than non-users. The number of herbals used was moderately correlated with the Morisky score. In stepwise, multivariate logistic regression analysis, herbal use was significantly associated with low medication adherence.

From these findings, the authors conclude that herbal use was found to be independently associated with low medication adherence in our study population.

So far, the main known risk of herbal medicine use was the possibility that there might be herb-drug interactions. To the best of my knowledge, nobody has yet studied the possibility that herbal medicine users might neglect to take their prescribed drugs. The results of this investigation are somewhat worrying but they do make sense. Some patients who buy and take herbal remedies might think that they do not need to regularly take their prescribed medications because they already take herbal medicine which takes care of their health problem. They might even have been told by their herbalist that the herbal remedies suffice.

If that is so, and if the phenomenon can be confirmed in further investigations, it should be relevant not just in cardiology but in all fields of medicine. And if that is true for herbal remedies, it might also be the case for other types of alternative medicine. In other words, alternative medicine use might be a marker for poor adherence to prescribed medication. I feel that this hypothesis merits further study.

It goes without saying that poor adherence to prescribed drugs can be a very dangerous habit. Clinicians should therefore warn their patients and tell them that herbal remedies are no replacement of prescription drugs.
