Radix Salviae Miltiorrhizae (Danshen) is a herbal remedy that is part of many TCM herbal mixtures. Allegedly, Danshen has been used in clinical practice for over 2000 years.
But is it effective?
The aim of this systematic review was to evaluate the current available evidence of Danshen for the treatment of cancer. English and Chinese electronic databases were searched from PubMed, the Cochrane Library, EMBASE, and the China National Knowledge Infrastructure (CNKI), VIP database, Wanfang database until September 2018. The methodological quality of the included studies was evaluated by using the method of Cochrane system.
Thirteen RCTs with 1045 participants were identified. The studies investigated the lung cancer (n = 5), leukemia (n = 3), liver cancer (n = 3), breast or colon cancer (n = 1), and gastric cancer (n = 1). A total of 83 traditional Chinese medicines were used in all prescriptions and there were three different dosage forms. The meta-analysis suggested that Danshen formulae had a significant effect on RR (response rate) (OR 2.38, 95% CI 1.66-3.42), 1-year survival (OR 1.70 95% CI 1.22-2.36), 3-year survival (OR 2.78, 95% CI 1.62-4.78), and 5-year survival (OR 8.45, 95% CI 2.53-28.27).
The authors concluded that the current research results showed that Danshen formulae combined with chemotherapy for cancer treatment was better than conventional drug treatment plan alone.
I am getting a little tired of discussing systematic reviews of so-called alternative medicine (SCAM) that are little more than promotion, free of good science. But, because such articles do seriously endanger the life of many patients, I do nevertheless succumb occasionally. So here are a few points to explain why the conclusions of the Chinese authors are nonsense:
- Even though the authors claim the trials included in their review were of high quality, most were, in fact, flimsy.
- The trials used no less than 83 different herbal mixtures of dubious quality containing Danshen. It is therefore not possible to define which mixture worked and which did not.
- There is no detailed discussion of the adverse effects and no mention of possible herb-drug interactions.
- There seemed to be a sizable publication bias hidden in the data.
- All the eligible studies were conducted in China, and we know that such trials are unreliable to say the least.
- Only four articles were published in English which means those of us who cannot read Chinese are unable to check the correctness of the data extraction of the review authors.
I know it sounds terribly chauvinistic, but I do truly believe that we should simply ignore Chinese articles, if they have defects that set our alarm bells ringing – if not, we are likely to do a significant disservice to healthcare and progress.
Reiki is a form of energy healing popularised by the Japanese Mikao Usui (1865-1926). ‘Rei’ means universal spirit (sometimes thought of as a supreme being), and ‘ki’ is the assumed universal life energy. Reiki is broadly based on some of the obsolete concepts of Traditional Chinese Medicine. Reiki practitioners believe that they can transfer ‘healing energy’ to a patient which, in turn, stimulates the self-healing properties of the body. They assume that the therapeutic effects of this technique are obtained from a ‘universal life energy’ that provides strength, harmony, and balance to the body and mind.
This study (entitled ‘ The Power of Reiki’) was conducted to pilot testing the feasibility and efficacy of Reiki to provide pain relief among pediatric patients undergoing hematopoietic stem cell transplantation (HSCT). Paediatric patients undergoing HSCT during the inpatient phase in the Stem Cell Transplantation Unit were eligible to participate. Short and medium effects were assessed investigating the increase or decrease of patient’s pain during three specific time periods (“delta”) of the day: morning of the Reiki session versus assessment before Reiki session (within subjects control period), assessment before Reiki session versus assessment after Reiki session (within subjects experimental period) and assessment after Reiki session versus morning the day after Reiki session (within subject follow-up period). The effect of 88 Reiki therapy sessions in nine patients was analysed following a short, medium, and long-term perspective. Repeated-measures analysis of variance revealed a significant difference among the three periods: a decrease of the pain occurred in the experimental period in short and medium term, while in the follow-up period, the pain level remained stable.
The authors concluded that this study demonstrates the feasibility of using Reiki therapy in pediatric cancer patients undergoing HSCT. Furthermore, these findings evidence that trained pediatric oncology nurses can insert Reiki into their clinical practice as a valid instrument for diminishing suffering from cancer in childhood.
This is an unusual conclusion in that it is strictly speaking correct. What is wrong, however, that the abstract reports findings related to the alleged effectiveness of Reiki. A feasibility study is not designed for that purpose. I therefore suggest to ignore all allusions to therapeutic effects.
This, I think, begs the question as to why it is necessary or productive to study Reiki in clinical trials.
- The treatment is not plausible.
- There have been many trials already.
- The ones that are sufficiently rigorous fail to show that it has any effects beyond placebo.
- The medical literature is already highly polluted with Reiki studies reporting false-positive results.
- This can only confuse researchers who attempt to conduct reviews on the subject.
- Reiki studies discredit clinical research.
- They are a waste of valuable resources.
- Arguably, they are even unethical.
If you ask me, it is high time to stop researching such implausible nonsense.
What on earth is this new SCAM?
Do I really have a ‘biofield’?
How can I tune it?
And what effect does it have?
Here is an article that explains all this in some detail; enjoy:
While western science has yet to describe and measure this energy, other cultures, especially ancient Indian or Vedic cultures describe it extensively. The term “chakra” (wheel) in Sanskirt, refers to spinning energy vortices which are seen as structures in the body’s subtle energy anatomy. Not coincidentally, within the body at each chakra location there is a corresponding large cluster of nerves or plexuses.
One way of understanding subtle energy is through the analogy “subtle energy is to electromagnetism as water vapor is to water.” Just as we do not measure water vapor with the same tools we use to measure water, we can’t use the same tools to measure subtle energy we would use to measure electricity. Subtle energy is higher, finer, more diffuse and follows slightly different laws.
Another word for this energy is “bioplasma.” Bioplasma is a diffuse magnetic fluid which surrounds all living beings. Like a fluid, it can be of varying viscosities and densities. In Biofield Tuning (also known as “sound balancing”, we see the human biofield as a bioplasmic toroid-shaped (doughnut-shaped) bubble which surrounds the body at a distance of about five feet to the sides and two-three feet at the top and bottom; bounded by a double layer plasma membrane much like the protective boundary which defines the earth’s upper atmosphere.
During a Biofield Tuning session, a client lies fully clothed on a treatment table while the practitioner activates a tuning fork and scans the body slowly beginning from a distance. The practitioner is feeling for resistance and turbulence in the client’s energy field, as well as listening for a change in the overtones and undertones of the tuning fork. When the practitioner encounters a turbulent area he/she continues to activate the tuning fork and hold it in that specific spot. Research suggests the body’s organizational energy uses the steady coherent vibrational frequency of the tuning fork to “tune” itself. In short order, the dissonance resolves and the sense of resistance gives way. This appears to correspond to the release of tension within the body.
Practitioners work with the “Biofield Anatomy Map“, a compilation of Biofield Tuning’s founder, Eileen Day McKusick’s 20+ years of biofield observations. Areas of dissonance can be pinpointed to a specific age and type of memory. For example, one might find a strong sense of sadness at age 12 or birth trauma at the outer edge of the biofield.
Holding an activated tuning fork in the area of a traumatic memory or another difficult time period produces repeatable, predictable outcomes. The sound input seems to help the body digest and integrate unprocessed experiences. As the biofield dissonance subsides, clients generally report feeling “lighter” and a diminishment or resolution of their symptoms.
The Sonic Slider is a custom-made weighted tuning fork that harnesses the power of therapeutic sound to help you feel and look younger and healthier.
Users report a wide range of benefits including more energy, greater well-being, weight loss, increased muscle tone, smoother skin, reduced pain, improved circulation and more.
Did I promise too much? Surely, you must agree, this is FANTASTIC!
I am so glad that someone has closely studied my instructions and followed them almost to the dot – my instructions as to HOW TO BECOME A CHARLATAN. In case you have forgotten, I repeat them here:
1. Find an attractive therapy and give it a fantastic name
Most of the really loony ideas turn out to be taken: ear candles, homeopathy, aura massage, energy healing, urine-therapy, chiropractic etc. As a true charlatan, you want your very own quackery. So you will have to think of a new concept.
Something truly ‘far out’ would be ideal, like claiming the ear is a map of the human body which allows you to treat all diseases by doing something odd on specific areas of the ear – oops, this territory is already occupied by the ear acupuncture brigade. How about postulating that you have super-natural powers which enable you to send ‘healing energy’ into patients’ bodies so that they can repair themselves? No good either: Reiki-healers might accuse you of plagiarism.
But you get the gist, I am sure, and will be able to invent something. When you do, give it a memorable name, the name can make or break your new venture.
2. Invent a fascinating history
Having identified your treatment and a fantastic name for it, you now need a good story to explain how it all came about. This task is not all that tough and might even turn out to be fun; you could think of something touching like you cured your moribund little sister at the age of 6 with your intervention, or you received the inspiration in your dreams from an old aunt who had just died, or perhaps you want to create some religious connection [have you ever visited Lourdes?]. There are no limits to your imagination; just make sure the story is gripping – one day, they might make a movie of it.
3. Add a dash of pseudo-science
Like it or not, but we live in an age where we cannot entirely exclude science from our considerations. At the very minimum, I recommend a little smattering of sciency terminology. As you don’t want to be found out, select something that only few experts understand; quantum physics, entanglement, chaos-theory and Nano-technology are all excellent options.
It might also look more convincing to hint at the notion that top scientists adore your concepts, or that whole teams from universities in distant places are working on the underlying mechanisms, or that the Nobel committee has recently been alerted etc. If at all possible, add a bit of high tech to your new invention; some shiny new apparatus with flashing lights and digital displays might be just the ticket. The apparatus can be otherwise empty – as long as it looks impressive, all is fine.
4. Do not forget a dose of ancient wisdom
With all this science – sorry, pseudo-science – you must not forget to remain firmly grounded in tradition. Your treatment ought to be based on ancient wisdom which you have rediscovered, modified and perfected. I recommend mentioning that some of the oldest cultures of the planet have already been aware of the main pillars on which your invention today proudly stands. Anything that is that old has stood the test of time which is to say, your treatment is both effective and safe.
5. Claim to have a panacea
To maximise your income, you want to have as many customers as possible. It would therefore be unwise to focus your endeavours on just one or two conditions. Commercially, it is much better to affirm in no uncertain terms that your treatment is a cure for everything, a panacea. Do not worry about the implausibility of such a claim. In the realm of quackery, it is perfectly acceptable, even common behaviour to be outlandish.
6. Deal with the ‘evidence-problem’ and the nasty sceptics
It is depressing, I know, but even the most exceptionally gifted charlatan is bound to attract doubters. Sceptics will sooner or later ask you for evidence; in fact, they are obsessed by it. But do not panic – this is by no means as threatening as it appears. The obvious solution is to provide testimonial after testimonial.
You need a website where satisfied customers report impressive stories how your treatment saved their lives. In case you do not know such customers, invent them; in the realm of quackery, there is a time-honoured tradition of writing your own testimonials. Nobody will be able to tell!
7. Demonstrate that you master the fine art of cheating with statistics
Some of the sceptics might not be impressed, and when they start criticising your ‘evidence’, you might need to go the extra mile. Providing statistics is a very good way of keeping them at bay, at least for a while. The general consensus amongst charlatans is that about 70% of their patients experience remarkable benefit from whatever placebo they throw at them. So, my advice is to do a little better and cite a case series of at least 5000 patients of whom 76.5 % showed significant improvements.
What? You don’t have such case series? Don’t be daft, be inventive!
8. Score points with Big Pharma
You must be aware who your (future) customers are (will be): they are affluent, had a decent education (evidently without much success), and are middle-aged, gullible and deeply alternative. Think of Prince Charles! Once you have empathised with this mind-set, it is obvious that you can profitably plug into the persecution complex which haunts these people.
An easy way of achieving this is to claim that Big Pharma has got wind of your innovation, is positively frightened of losing millions, and is thus doing all they can to supress it. Not only will this give you street cred with the lunatic fringe of society, it also provides a perfect explanation why your ground-breaking discovery has not been published it the top journals of medicine: the editors are all in the pocket of Big Pharma, of course.
9. Ask for money, much money
I have left the most important bit for the end; remember: your aim is to get rich! So, charge high fees, even extravagantly high ones. If your treatment is a product that you can sell (e.g. via the internet, to escape the regulators), sell it dearly; if it is a hands-on therapy, charge heavy consultation fees and claim exclusivity; if it is a teachable technique, start training other therapists at high fees and ask a franchise-cut of their future earnings.
Over-charging is your best chance of getting famous – or have you ever heard of a charlatan famous for being reasonably priced? It will also get rid of the riff-raff you don’t want to see in your surgery. Poor people might be even ill! No, you don’t want them; you want the ‘worried rich and well’ who can afford to see a real doctor when things should go wrong. But most importantly, high fees will do a lot of good to your bank account.
I must say, it is truly satisfying to see one’s advice taken so literally!
Bleach can be a useful product – but not as a medicine taken by mouth or for injection.
A 39-year-old man with a fracture of the right acetabulum underwent open reduction and internal fixation with a plate under general anaesthesia. At closure, the surgeons injected 0.75% ropivacaine into the subcutaneous tissue of the incision wound for postoperative analgesia. Soon after injection, subcutaneous emphysema at the injection site and a sudden decrease in end-tidal CO2 tension with crude oscillatory ripples during the alveolar plateau phase were observed. Shortly thereafter, it was found that the surgeons had mistakenly injected hydrogen peroxide instead of ropivacaine. Fortunately, the patient recovered to normal status after 10 minutes. After the surgery, the patient was carefully observed for suspected pulmonary embolism and discharged without complications.
A team from Morocco reported the case of a massive embolism after hydrogen peroxide use in the cleaning of infected wound with osteosynthesis material left femoral done under spinal anaesthesia in a young girl of 17 years admitted after to the ICU intubated ventilated. She was placed under mechanical ventilation with vasoactive drugs for ten hours and then extubated without neurological sequelae.
Tunisian doctors reported 2 cases of embolic events with neurological signs. The first, during a pleural cleaning with hydrogen peroxide after cystectomy of a pulmonary hydatic cyst at the right upper lobe. The second case, after a pleural washing during the treatment of hepatitic hydatidosis complicated by a ruptured cyst in the thorax.
Canadian anaesthetists reported a case of suspected oxygen venous embolism during lumbar discectomy in the knee-prone position after use of H2O2. Immediately after irrigation of a discectomy wound with H2O2, a dramatic decrease of the PETCO2, blood pressure and oxygen saturation coincident with ST segment elevation occurred suggesting a coronary gas embolism. Symptomatic treatment was initiated immediately and the patient recovered without any sequelae.
Indian nephrologists reported a case of chlorine dioxide poisoning presenting with acute kidney injury.
A 1-year-old boy presented to the emergency department with vomiting and poor complexion after accidentally ingesting a ClO2-based household product. The patient had profound hypoxia that did not respond to oxygen therapy and required endotracheal intubation to maintain a normal oxygen level. Methemoglobinemia was suspected based on the gap between SpO2 and PaO2, and subsequently increased methemoglobin at 8.0% was detected. The patient was admitted to the paediatric intensive care unit for further management. After supportive treatment, he was discharged without any complications. He had no cognitive or motor dysfunction on follow up 3 months later.
The medical literature is littered with such case-reports. They give us a fairly good idea that the internal use of bleach is not a good idea. In fact, it has caused several deaths. Yet, this is precisely what some SCAM practitioners are advocating.
Now one of them is in court for manslaughter. “If I am such a clear and present danger and a murderer, I should be in jail by now,” said doctor Shortt, who despite a criminal investigation, is still treating patients in his office on the outskirts of Columbia, S.C. Shortt got his medical degree 13 years ago on the Caribbean island of Montserrat. Being a “longevity physician” didn’t seem to bother anyone until one of his patients wound up dead. Shortt gave her an infusion of hydrogen peroxide. Katherine Bibeau, a medical technologist and a mother of two, had been battling multiple sclerosis for two years, and was looking for any treatment that might keep her out of a wheelchair. According to her husband, doctor Shortt said hydrogen peroxide was just the thing. “He had said that there was other people who had been in wheelchairs, and had actually gone through treatment and were now walking again.” It didn’t worry the Bibeaus that Shortt wasn’t affiliated with any hospital or university – and that insurance didn’t cover most of his treatments. “He was a licensed medical doctor in Carolina,” says Bibeau. “So I put my faith in those credentials.” According to Shortt’s own records, the patient subsequently complained of “nausea,” “leg pain,” and later “bruises” with no clear cause. “She went Tuesday, she went Thursday. And by 11 o’clock on Sunday, she died,” says Mr Bibeau. Shortt never told him or his wife about any serious risks. “Even if it wasn’t effective, it should not have been harmful.”
Shortt has been putting hydrogen peroxide in several of his patients’ veins, because he believes it can effectively treat illnesses from AIDS to the common cold. “I think it’s an effective treatment for the flu,” says Shortt, who also believes that it’s effective for multiple sclerosis, Lyme disease, and “as adjunctive therapy” for heart disease. “Things that involve the immune system, viruses, bacteria, sometimes parasites.”
He’s not the only physician using this treatment. Intravenous hydrogen peroxide is a SCAM touted as a cure the medical establishment doesn’t want you to know about. There even is an association that claims to have trained hundreds of doctors how to administer it. The theory is that hydrogen peroxide releases extra oxygen inside the body, killing viruses and bacteria.
Natural News, for instance, tells us that cancer has a rival that destroys it like an M-60 leveling a field of enemy soldiers. It’s called “hydrogen peroxide,” and the “lame-stream,” mainstream media will tell you how “dangerous” it is at 35%, but they won’t tell you that you can drip a couple drops in a glass of water each day and end cancer. Yes, it’s true.
And hydrogen peroxide is not the only bleach that found its way into the realm of SCAM.
Perhaps even worse (if that is possible), the Genesis II Church of Health and Healing promote MMS as a miracle cure. It consists of chlorine dioxide, a powerful bleach that has been banned in several countries around the world for use as a medical treatment. The ‘Church’ claim that MMS cures 95% of all diseases in the world by making adults and children, including infants, drink industrial bleach. The group is inviting members to attend what they call their “effective alternative healing”.
The organizer of the event, Tom Merry, has publicized it by telling people that learning how to consume the bleach “could save your life, or the life of a loved one sent home to die”. The “church” is asking attendants of the meeting to “donate” $450 each, or $800 per couple, in exchange for receiving membership to the organization as well as packages of the bleach, which they call “sacraments”. The chemical is referred to as MMS, or “miracle mineral solution or supplement”, and participants are promised they will acquire “the knowledge to help heal many people of this world’s terrible diseases”.
Fiona O’Leary, a tireless and courageous campaigner for putting an end to a wide variety of mistreatments of children and adults, whose work helped to get MMS banned in Ireland, said she was horrified that the Genesis II Church, which she called a “bleach cult”, was hosting a public event in Washington.
In Fiona’s words: “ Its experimentation and abuse”. I do agree and might just add this: selling bleach for oral or intravenous application, while pretending it is an effective medicine, seems criminal as well.
Chiropractic spinal manipulative therapy (CSMT) for migraine?
There is no good evidence that it works!
On the contrary, there is good evidence that it does NOT work!
A recent and rigorous study (conducted by chiropractors!) tested the efficacy of chiropractic CSMT for migraine. It was designed as a three-armed, single-blinded, placebo -controlled RCT of 17 months duration including 104 migraineurs with at least one migraine attack per month. Active treatment consisted of CSMT (group 1) and the placebo was a sham push manoeuvre of the lateral edge of the scapula and/or the gluteal region (group 2). The control group continued their usual pharmacological management (group 3). The results show that migraine days were significantly reduced within all three groups from baseline to post-treatment. The effect continued in the CSMT and placebo groups at all follow-up time points (groups 1 and 2), whereas the control group (group 3) returned to baseline. The reduction in migraine days was not significantly different between the groups. Migraine duration and headache index were reduced significantly more in the CSMT than in group 3 towards the end of follow-up. Adverse events were few, mild and transient. Blinding was sustained throughout the RCT. The authors concluded that the effect of CSMT observed in our study is probably due to a placebo response.
One can understand that, for chiropractors, this finding is upsetting. After all, they earn a good part of their living by treating migraineurs. They don’t want to lose patients and, at the same time, they need to claim to practise evidence-based medicine.
What is the way out of this dilemma?
They only need to publish a review in which they dilute the irritatingly negative result of the above trial by including all previous low-quality trials with false-positive results and thus generate a new overall finding that alleges CSMT to be evidence-based.
This new systematic review of randomized clinical trials (RCTs) evaluated the evidence regarding spinal manipulation as an alternative or integrative therapy in reducing migraine pain and disability.
The searches identified 6 RCTs eligible for meta-analysis. Intervention duration ranged from 2 to 6 months; outcomes included measures of migraine days (primary outcome), migraine pain/intensity, and migraine disability. Methodological quality varied across the studies. The results showed that spinal manipulation reduced migraine days with an overall small effect size as well as migraine pain/intensity.
The authors concluded that spinal manipulation may be an effective therapeutic technique to reduce migraine days and pain/intensity. However, given the limitations to studies included in this meta-analysis, we consider these results to be preliminary. Methodologically rigorous, large-scale RCTs are warranted to better inform the evidence base for spinal manipulation as a treatment for migraine.
Bob’s your uncle!
Perhaps not perfect, but at least the chiropractic profession can now continue to claim they practice something akin to evidence-based medicine, while happily cashing in on selling their unproven treatments to migraineurs!
But that’s not very fair; research is not for promotion, research is for finding the truth; this white-wash is not in the best interest of patients! I hear you say.
Who cares about fairness, truth or conflicts of interest?
Christine Goertz, one of the review-authors, has received funding from the NCMIC Foundation and served as the Director of the Inter‐Institutional Network for Chiropractic Research (IINCR). Peter M. Wayne, another author, has received funding from the NCMIC Foundation and served as the co‐Director of the Inter‐Institutional Network for Chiropractic Research (IINCR)
And who the Dickens are the NCMIC and the IINCR?
At NCMIC, they believe that supporting the chiropractic profession, including chiropractic research programs and projects, is an important part of our heritage. They also offer business training and malpractice risk management seminars and resources to D.C.s as a complement to the education provided by the chiropractic colleges.
The IINCR is a collaborative effort between PCCR, Yale Center for Medical Informatics and the Osher Center for Integrative Medicine at Brigham and Women’s Hospital and Harvard Medical School. They aim at creating a chiropractic research portfolio that’s truly translational. Vice Chancellor for Research and Health Policy at Palmer College of Chiropractic Christine Goertz, DC, PhD (PCCR) is the network director. Peter Wayne, PhD (Osher Center for Integrative Medicine at Brigham and Women’s Hospital and Harvard Medical School) will join Anthony J. Lisi, DC (Yale Center for Medical Informatics and VA Connecticut Healthcare System) as a co-director. These investigators will form a robust foundation to advance chiropractic science, practice and policy. “Our collective efforts provide an unprecedented opportunity to conduct clinical and basic research that advances chiropractic research and evidence-based clinical practice, ultimately benefiting the patients we serve,” said Christine Goertz.
Really: benefiting the patients?
You could have fooled me!
The aim of this new systematic review was to evaluate the controlled trials of homeopathy in bronchial asthma. Relevant trials published between Jan 1, 1981, and Dec 31, 2016, were considered. Substantive research articles, conference proceedings, and master and doctoral theses were eligible. Methodology was assessed by Jadad’s scoring, internal validity by the Coch-rane tool, model validity by Mathie’s criteria, and quality of individualization by Saha’s criteria.
Sixteen trials were eligible. The majority were positive, especially those testing complex formulations. Methodological quality was diverse; 8 trials had “high” risk of bias. Model validity and individualization quality were compromised. Due to both qualitative and quantitative inadequacies, proofs supporting individualized homeopathy remained inconclusive. The trials were positive (evidence level A), but inconsistent, and suffered from methodological heterogeneity, “high” to “uncertain” risk of bias, incomplete study reporting, inadequacy of independent replications, and small sample sizes.
The authors of this review come from:
- the Department of Homeopathy, District Joint Hospital, Government of Bihar, Darbhanga, India;
- the Department of Organon of Medicine and Homoeopathic Philosophy, Sri Sai Nath Postgraduate Institute of Homoeopathy, Allahabad, India;
- the Homoeopathy University Jaipur, Jaipur, India;
- the Central Council of Homeopathy, Hooghly,
- the Central Council of Homeopathy, Howrah, India
They state that they have no conflicts of interest.
The review is puzzling on so many accounts that I had to read it several times to understand it. Here are just some of its many oddities:
- According to its authors, the review adhered to the PRISMA-P guideline; as a co-author of this guideline, I can confirm that this is incorrect.
- The authors claim to have included all ‘controlled trials (randomized, non-randomized, or observational) of any form of homeopathy in patients suffering from persistent and chronic bronchial asthma’. In fact, they also included uncontrolled studies (16 controlled trials and 12 uncontrolled observational studies, to be precise).
- The authors included papers published between Jan 1, 1981, and Dec 31, 2016. It is unacceptable, in my view, to limit a systematic review in this way. It also means that the review was seriously out of date already on the day it was published.
- The authors tell us that they applied no language restrictions. Yet they do not inform us how they handled papers in foreign languages.
- Studies of homeopathy as a stand alone therapy were included together with studies of homeopathy as an adjunct. Yet the authors fail to point out which studies belonged to which category.
- Several of the included studies are not of homeopathy but of isopathy.
- The authors fail to detail their results and instead refer to an ‘online results table’ which I cannot access even though I have the on-line paper.
- Instead, they report that 28 studies were included and ‘thus, the level of evidence was graded as A.’
- No direction of outcome was provided in the results section. All we do learn from the paper’s discussion section is that ‘the majority of the studies were positive, and the level of evidence could be graded as A (strong scientific evidence)’.
- Despite the high risk of bias in most of the included studies, the authors suggest a ‘definite role of homeopathy beyond placebo in the treatment of bronchial asthma’.
- The current Cochrane review (also authored by a pro-homeopathy team) concluded that there is not enough evidence to reliably assess the possible role of homeopathy in asthma. Yet the authors of this new review do not even attempt to explain the contradiction.
The purpose of this recently published survey was to obtain the demographic profile and educational background of chiropractors with paediatric patients on a multinational scale.
A multinational online cross-sectional demographic survey was conducted over a 15-day period in July 2010. The survey was electronically administered via chiropractic associations in 17 countries, using SurveyMonkey for data acquisition, transfer, and descriptive analysis.
The response rate was 10.1%, and 1498 responses were received from 17 countries on 6 continents. Of these, 90.4% accepted paediatric cases. The average practitioner was male (61.1%) and 41.4 years old, had 13.6 years in practice, and saw 107 patient visits per week. Regarding educational background, 63.4% had a bachelor’s degree or higher in addition to their chiropractic qualification, and 18.4% had a postgraduate certificate or higher in paediatric chiropractic.
The authors from the Anglo-European College of Chiropractic (AECC), Bournemouth University, United Kingdom, drew the following conclusion: this is the first study about chiropractors who treat children from the United Arab Emirates, Peru, Japan, South Africa, and Spain. Although the response rate was low, the results of this multinational survey suggest that pediatric chiropractic care may be a common component of usual chiropractic practice on a multinational level for these respondents.
A survey with a response rate of 10%?
An investigation published 9 years after it has been conducted?
Who at the AECC is responsible for controlling the quality of the research output?
Or is this paper perhaps an attempt to get the AECC into the ‘Guinness Book of Records’ for outstanding research incompetence?
But let’s just for a minute pretend that this paper is of acceptable quality. If the finding that ~90% of chiropractors tread kids is approximately correct, one has to be very concerned indeed.
I am not aware of any good evidence that chiropractic care is effective for paediatric conditions. On the contrary, it can do quite a bit of direct harm! To this, we sadly also have to add the indirect harm many chiropractors cause, for instance, by advising parents against vaccinating their kids.
This clearly begs the question: is it not time to stop these charlatans?
What do you think?
The aim of this systematic review was to determine the efficacy of conventional treatments plus acupuncture versus conventional treatments alone for asthma, using a meta-analysis of all published randomized clinical trials (RCTs).
The researchers included all RCTs in which adult and adolescent patients with asthma (age ≥12 years) were divided into conventional treatments plus acupuncture (A+B) and conventional treatments (B). Nine studies were included. The results showed that A+B could improve the symptom response rate and significantly decrease interleukin-6. However, indices of pulmonary function, including the forced expiratory volume in one second (FEV1) and FEV1/forced vital capacity (FVC) failed to be improved with A+B.
The authors concluded that conventional treatments plus acupuncture are associated with significant benefits for adult and adolescent patients with asthma. Therefore, we suggest the use of conventional treatments plus acupuncture for asthma patients.
I am thankful to the authors for confirming my finding that A+B must always be more/better than B alone (the 2nd sentence of their conclusion is, of course, utter nonsense, but I will leave this aside for today). Here is the short abstract of my 2008 article:
In this article, we test the hypothesis that randomized clinical trials of acupuncture for pain with certain design features (A + B versus B) are likely to generate false positive results. Based on electronic searches in six databases, 13 studies were found that met our inclusion criteria. They all suggested that acupuncture is effective (one only showing a positive trend, all others had significant results). We conclude that the ‘A + B versus B’ design is prone to false positive results and discuss the design features that might prevent or exacerbate this problem.
Even though our paper was on acupuncture for pain, it firmly established the principle that A+B is always more than B. Think of it in monetary terms: let’s say we both have $100; now someone gives me $10 more. Who has more cash? Not difficult, is it?
But why do SCAM-fans not get it?
Why do we see trial after trial and review after review ignoring this simple and obvious fact?
I suspect I know why: it is because the ‘A+B vs B’ study-design never generates a negative result!
But that’s cheating!
And isn’t cheating unethical?
My answer is YES!

This paper reports a survey amongst European chiropractors during early 2017. Dissemination was through an on-line platform with links to the survey being sent to all European chiropractic associations regardless of European Chiropractors’ Union (ECU) membership and additionally through the European Academy of Chiropractic (EAC). Social media via Facebook groups was also used to disseminate links to the survey.
One thousand three hundred twenty and two responses from chiropractors across Europe representing approximately 17.2% of the profession were collected. Five initial self-determined chiropractic identities were collapsed into 2 groups categorised as orthodox (79.9%) and unorthodox (20.1%); by the latter term, the investigators mean the subluxationists/vitalists.
When comparing the percentage of new patients chiropractors x-rayed, 23% of the unorthodox group x-rayed > 50% of their new patients compared to 5% in the orthodox group. Furthermore, the proportion of respondents reporting > 150 patient encounters per week in the unorthodox group were double compared to the orthodox (22 v 11%). Lastly the proportion of those respondents disagreeing or strongly disagreeing with the statement “In general, vaccinations have had a positive effect on global public health” was 57 and 4% in unorthodox and orthodox categories respectively. Logistic regression models identified male gender, seeing more than 150 patients per week, no routine differential diagnosis, and not strongly agreeing that vaccines have generally had a positive impact on health as highly predictive of unorthodox categorisation.
The authors concluded that despite limitations with generalisability in this survey, the proportion of respondents adhering to the different belief categories are remarkably similar to other studies exploring this phenomenon. In addition, and in parallel with other research, this survey suggests that key practice characteristics in contravention of national radiation guidelines or opposition to evidence based public health policy are significantly more associated with non-orthodox chiropractic paradigms.
N (%) Orthodox
N (%) Unorthodox
Here is the abstract of a paper that makes even the most senior assessor of quackery shudder:
The purpose of this report is to describe the manipulation under anesthesia (MUA) treatment of 6 infants with newborn torticollis with a segmental dysfunction at C1/C2.
Six infants aged 4 1/2 to 15 months previously diagnosed with newborn torticollis were referred to a doctor of chiropractic owing to a failure to respond adequately to previous conservative therapies. Common physical findings were limited range of motion of the upper cervical spine. Radiographs demonstrated rotational malpositions and translation of atlas on axis in all 6 infants, and 1 had a subluxation of the C1/C2 articulation.
Interventions and Outcome:
Selection was based on complexity and variety of different clinical cases qualifying for MUA. Treatment consisted of 1 mobilization and was performed in the operating room of a children’s hospital by a certified chiropractic physician with the author assisting. Along with the chiropractor and his assistant, a children’s anesthesiologist, 1 to 2 operating nurses, a children’s radiologist, and in 1 case a pediatric surgeon were present. Before the mobilization, plain radiographs of the cervico-occipital area were taken. Three infants needed further investigation by a pediatric computed tomography scan of the area because of asymmetric bony conditions on the plain radiographs. Follow-up consultations at 2, 3, 5, or 6 weeks were done. Patient records were analyzed for restriction at baseline before MUA compared with after MUA treatment for active rotation, passive rotation, and passive rotation in full flexion of the upper cervical spine. All 3 measurements showed significant differences. The long-term outcome data was collected via phone calls to the parents at 6 to 72 months. The initial clinical improvements were maintained.
These 6 infants with arthrogenic newborn torticollis, who did not respond to previous conservative treatment methods, responded to MUA.
After reading the full text, I see many very serious problems and questions with this paper; here are 14 of the most obvious ones.
1. A congenital torticollis (that’s essentially what these kids were suffering from) has a good prognosis and does not require such invasive treatments. There is thus no plausible reason to conduct a case series of this nature.
2. A retrospective case series does not allow conclusions about therapeutic effectiveness, yet in the article the author does just that.
3. The same applies to her conclusions about the safety of the interventions.
4. It is unclear how the 6 cases were selected; it seems possible or even likely that they are, in fact, 6 cases of many more treated over a long period of time.
5. If so, this paper is hardly a ‘retrospective case series’; at best it could be called a ‘best case series’.
6. The X-rays or CT scans are unnecessary and potentially harmful.
7. The anaesthesia is potentially very harmful and unjustifiable.
8. The outcome measure is unreliable, particularly if performed by the chiropractor who has a vested interest in generating a positive result.
9. The follow-up by telephone is inadequate.
10. The range of the follow-up period (6-72 months) is unacceptable.
11. The exact way in which informed consent was obtained is unclear. In particular, we would need to know whether the parents were fully informed about the futility of the treatment and its considerable risks.
12. The chiropractor who administered the treatments is not named. Why not?
13. Similarly, it is unclear why the other healthcare professionals involved in these treatments are not named as co-authors of the paper.
14. It is unclear whether ethical approval was obtained for these treatments.
The author seems inexperienced in publishing scientific articles; the present one is poorly written and badly constructed. A Medline research reveals that she has only one other publication to her name. So, perhaps one should not be too harsh in judging her. But what about her supervisors, the journal, its reviewers, its editor and the author’s institution? The author comes from the Department of Chiropractic Medicine, Medical Faculty University, Zurich, Switzerland. On their website, they state:
The Faculty of Medicine of the University of Zurich is committed to high quality teaching and continuing research-based education of students in health care professions. Excellent and internationally recognised scientists and clinically outstanding physicians are at the Faculty of Medicine devoted to patients and public health, to teaching, to the support of young researchers and to academic medicine. The interaction between research and teaching, and their connection to clinical practice play a central role for us…
The Faculty of Medicine of the University of Zurich promotes innovative research in the basic fields of medicine, in the clinical application of knowledge, in personalised medicine, in health care, and in the translational connection between all these research areas. In addition, it encourages the cooperation between primary care and specialised health care.
It seems that, with the above paper, the UZH must have made an exception. In my view, it is a clear case of scientific misconduct and child abuse.
