The goal of this study was to assess clinical outcomes observed among adult patients who received acupuncture treatments at a United States Air Force medical center.
This retrospective chart review was performed at the Nellis Family Medicine Residency in the Mike O’Callaghan Military Medical Center at Nellis Air Force Base in Las Vegas, NV. The charts were from 172 consecutive patients who had at least 4 acupuncture treatments within 1 year. These patients were suffering from a wide range of symptoms, including pain, anxiety and sleep problems. The main outcome measures were prescriptions for opioid medications, muscle relaxants, benzodiazepines, and nonsteroidal anti-inflammatory drugs (NSAIDS) in the 60 days prior to the first acupuncture session and in the corresponding 60 days 1 year later; and Measure Yourself Medical Outcome Profile (MYMOP2) values for symptoms, ability to perform activities, and quality of life.
The most common 10 acupuncture treatments in descending order were: (1) the Auricular Trauma Protocol; (2) Battlefield Auricular Acupuncture; (3) Chinese scalp acupuncture, using the upper one-fifth of the sensory area and the Foot Motor Sensory Area; (4) the Koffman Cocktail; (5) lumbar percutaneous electrical nerve stimulation (PENS); (6) various auricular functional points; (7) Chinese scalp acupuncture, using the frontal triangle pattern; (8) cervical PENS; (9) the Great American Malady treatment; and (10) tendinomuscular meridian treatment with surface release.
The results show that opioid prescriptions decreased by 45%, muscle relaxants by 34%, NSAIDs by 42%, and benzodiazepines by 14%. MYMOP2 values decreased 3.50–3.11 (P < 0.002) for question 1, 4.18–3.46 (P < 0.00001) for question 3, and 2.73–2.43 (P < 0.006) for question 4.
The authors concluded that in this military patient population, the number of opioid prescriptions decreased and patients reported improved symptom control, ability to function, and sense of well-being after receiving courses of acupuncture by their primary care physicians.
The phraseology used by the authors is intriguing; they imply that the clinical outcomes were the result of the acupuncture treatment without actually stating it. This is perhaps most obvious in the title of the paper: Reduction in Pain Medication Prescriptions and Self-Reported Outcomes Associated with Acupuncture in a Military Patient Population. Association is not causation! But the implication of a cause effect relationship is clearly there. Once we realise who is behind this research we understand why: This study was funded by the ACUS Foundation as part of a Cooperative Research and Development Agreement with the 99th Medical Group, at Nellis Air Force Base.
The mission of Acus Foundation is to educate military physicians in the science and art of medical acupuncture, and to facilitate its integration into conventional military care… we are the most experienced team of physician teachers and practitioners of acupuncture in the United States. If they are so experienced, they surely also know that there are many explanations for the observed outcomes which are totally unrelated to acupuncture, e. g.:
- the natural history of the conditions that were being treated;
- the conventional therapies the soldiers received;
- the regression to the mean;
- social desirability;
- placebo effects.
In fact the results could even indicate that acupuncture caused a delay of clinical improvement; without a control group, we cannot know either way. All we can safely assume from this study is that it is yet another example of promotion masquerading as research.
The claimed benefits of Shinrin-yoku are remarkable:
- Boosted immune system functioning, with an increase in the count of the body’s Natural Killer (NK) cells.
- Reduced blood pressure
- Reduced stress
- Improved mood
- Increased ability to focus, even in children with ADHD
- Accelerated recovery from surgery or illness
- Increased energy level
- Improved sleep
- Deeper and clearer intuition
- Increased flow of energy
- Increased capacity to communicate with the land and its species
- Increased flow of eros/life force
- Deepening of friendships
- Overall increase in sense of happiness
But is any of this really true?
The aim of this state-of-the-art review was to summarise empirical research conducted on the physiological and psychological effects of Shinrin-Yoku. Research published from 2007 to 2017 was considered. A total of 64 studies met the inclusion criteria. According to the authors, they show that health benefits associated with the immersion in nature continue to be currently researched. Longitudinal research, conducted worldwide, is needed to produce new evidence of the relationships associated with Shinrin-Yoku and clinical therapeutic effects. Nature therapy as a health-promotion method and potential universal health model is implicated for the reduction of reported modern-day “stress-state” and “technostress.”
A look at the primary studies reveals that they are usually small and of poor quality.
Perhaps a brand new review aimed more specifically at evaluating preventive or therapeutic effects of Shinrin-Yoku on blood pressure can tell us more. The authors considered all published, randomized, controlled trials, cohort studies, and comparative studies that evaluated the effects of the forest environment on changes in systolic blood pressure. Twenty trials involving 732 participants were reviewed. Systolic and diastolic blood pressure of patients submitted to the forest environment was significantly lower than that of controls. The authors concluded that this systematic review shows a significant effect of Shinrin-yoku on reduction of blood pressure.
I find this paper odd as well:
- it lacks important methodological detail;
- the authors included not just controlled clinical trials but all sorts of ‘studies’;
- there is no assessment of the methodological rigor of the primary trials (from what I could see, they were mostly too poor to draw any conclusions from them).
What does all of this mean?
I have no problems in assuming that relaxation in a forest is beneficial in many ways and a nice experience.
But why call this a therapy?
It is relaxation!
Why make so many unsubstantiated claims?
And why study it in such obviously flawed ways?
All this does, I fear, is giving science a bad name.
This new RCT by researchers from the National Institute of Complementary Medicine in Sydney, Australia was aimed at ‘examining the effect of changing treatment timing and the use of manual, electro acupuncture on the symptoms of primary dysmenorrhea’. It had four arms:
- low frequency manual acupuncture (LF-MA),
- high frequency manual acupuncture (HF-MA),
- low frequency electro acupuncture (LF-EA)
- and high frequency electro acupuncture (HF-EA).
A total of 74 women were given 12 treatments over three menstrual cycles, either once per week (LF groups) or three times in the week prior to menses (HF groups). All groups received a treatment in the first 48 hours of menses. The primary outcome was the reduction in peak menstrual pain at 12 months from trial entry.
During the treatment period and 9 month follow-up all groups showed statistically significant reductions in peak and average menstrual pain compared to baseline. However, there were no differences between groups. Health related quality of life increased significantly in 6 domains in groups having high frequency of treatment compared to two domains in low frequency groups. Manual acupuncture groups required less analgesic medication than electro-acupuncture groups. HF-MA was most effective in reducing secondary menstrual symptoms compared to both–EA groups.
The authors concluded that acupuncture treatment reduced menstrual pain intensity and duration after three months of treatment and this was sustained for up to one year after trial entry. The effect of changing mode of stimulation or frequency of treatment on menstrual pain was not significant. This may be due to a lack of power. The role of acupuncture stimulation on menstrual pain needs to be investigated in appropriately powered randomised controlled trials.
If I were not used to reading rubbish research of alternative medicine in general and acupuncture in particular, this RCT would amaze me – not so much because of its design, execution, or write-up, but primarily because of its conclusion (why, oh why, I ask myself, did PLOS ONE publish this paper?). They are, I think, utterly barmy.
Let me explain:
- “acupuncture treatment reduced menstrual pain intensity” – oh no, it didn’t; at least this is not what the study proves; the fact that pain was perceived as less could be due to a host of factors, for instance regression towards the mean, or social desirability; as there was no proper control group, nobody can tell;
- the lack of difference between treatments “may be due to a lack of power”. Yes, but more likely it is due to the fact that all versions of a placebo therapy generate similar outcomes.
- “acupuncture stimulation on menstrual pain needs to be investigated in appropriately powered randomised controlled trials”. Why? Because the authors have a quasi-religious belief in acupuncture? And if they have, why did they not design their study ‘appropriately’?
The best conclusion I can suggest for this daft trial is this: IN THIS STUDY, THE PRIMARY ENDPOINT SHOWED NO DIFFERENCE BETWEEN THE 4 TREATMENT GROUPS. THE RESULTS ARE THEREFORE FULLY COMPATIBLE WITH THE NOTION THAT ACUPUNCTURE IS A PLACEBO THERAPY.
Something along these lines would, in my view, have been honest and scientific. Sadly, in acupuncture research, we very rarely get such honest science and the ‘National Institute of Complementary Medicine in Sydney, Australia’ has no track record of being the laudable exception to this rule.
I have repeatedly cautioned about the often poor quality of research into alternative medicine. This seems particularly necessary with studies of acupuncture, and especially true for such research carried out in China. I have also frequently noted that certain ‘CAM journals’ are notoriously prone to publishing rubbish. So, what can we expect from a paper that:
- is on alternative medicine,
- focusses on acupuncture,
- is authored by Chinese researchers,
- was published in the Journal of Alternative and Complementary Medicine (JACM)?
The answer is PROBABLY NOT A LOT!
As if for confirming my prediction, The JACM just published this systematic review. It reports pairwise and network meta-analyses to determine the effectiveness of acupuncture and acupuncture-related techniques for the treatment of psoriasis. A total of 13 RCTs were included. The methodological quality of these studies was ‘not rigorous’ according to the authors – in fact, it was lousy. Acupoint stimulation seemed to be more effective than non-acupoint stimulation. The short-term treatment effect was superior to the long-term effect (as one would expect with placebo). Network meta-analysis suggested that acupressure or acupoint catgut embedding generate superior effects compared to medications. It was noted that acupressure was the most effective treatment of all the acupuncture-like therapies.
The authors concluded that acupuncture-related techniques could be considered as an alternative or adjuvant therapy for psoriasis in short term, especially of acupressure and acupoint catgut embedding. This study recommends further well-designed, methodologically rigorous, and more head-to-head randomized trials to explore the effects of acupuncture-related techniques for treating psoriasis.
And what is wrong with that?
- The review is of very poor quality.
- The primary studies are even worse.
- The English language is defective to the point of being not understandable.
- The conclusions are misleading.
Correct conclusions should read something like this: Due to the paucity and the poor quality of the clinical trials, this review could not determine whether acupuncture and similar therapies are effective for psoriasis.
And then there is, of course, the question about plausibility. How plausible is the assumption that acupuncture might affect a genetic autoimmune disease like psoriasis. The answer, I think, is that the assumption is highly unlikely.
In the above review, most of the 13 primary RCTs were from China. One of the few studies not conducted in China is this one:
56 patients suffering from long-standing plaque psoriasis were randomized to receive either active treatment (electrostimulation by needles placed intramuscularly, plus ear-acupuncture) or placebo (sham, ‘minimal acupuncture‘) twice weekly for 10 weeks. The severity of the skin lesions was scored (PASI) before, during, and 3 months after therapy. After 10 weeks of treatment the PASI mean value had decreased from 9.6 to 8.3 in the ‘active’ group and from 9.2 to 6.9 in the placebo group (p < 0.05 for both groups). These effects are less than the usual placebo effect of about 30%. There were no statistically significant differences between the outcomes in the two groups during or 3 months after therapy. The patient’s own opinion about the results showed no preference for ‘active’ therapy. It was also clear from the answers that the blinded nature of the study had not been discovered by the patients. In conclusion, classical acupuncture is not superior to sham (placebo) ‘minimal acupuncture‘ in the treatment of psoriasis.
Somehow, I trust these conclusions more than the ones from the review!
And somehow, I get very tired of journal editors failing to do their job of rejecting papers that evidently are embarrassing, unethical rubbish.
Systematic reviews are aimed at summarising and critically evaluating the evidence on a specific research question. They are the highest level of evidence and are more reliable than anything else we have. Therefore, they represent a most useful tool for both clinicians and researchers.
But there are, of course, exceptions. Take, for instance, this recent systematic review by researchers from the
- Texas Chiropractic College, Pasadena, the Palmer Center for Chiropractic Research, Palmer College of Chiropractic, Davenport,
- Department of Planning, Policy and Design, University of California, Irvine,
- VA Puget Sound Health Care System, Tacoma,
- New York Chiropractic College, Seneca Falls,
- Logan University College of Chiropractic, Chesterfield,
- University of Western States, Portland.
The ‘Daily Mail’ is not a paper famed for its objective reporting. In politics, this can influence elections; in medicine, it can endanger public health.
A recent article is a case in point, I think.
START OF QUOTE
Traditional Chinese medicines could help prevent heart disease and the progression of pre-diabetes, according to research. Some herbal treatments proved as effective in lowering blood pressure as Western drugs and improved heart health by lowering cholesterol, scientists found. Certain alternative medicines could lower blood sugar and insulin levels, too.
Chinese medicines could be used alongside conventional treatments, say researchers from Shandong University Qilu Hospital in China. Or they can be beneficial as an alternative for patients intolerant of Western drugs, they said in their review of medical studies over a ten-year period. Senior review author from the university’s department of traditional Chinese medicine said: ‘The pharmacological effects and the underlying mechanisms of some active ingredients of traditional Chinese medications have been elucidated. Thus, some medications might be used as a complementary and alternative approach for primary and secondary prevention of cardiovascular disease.”
It’s potentially good news for people living with diabetes, which is now a global epidemic and has proved a tricky condition to manage for many people. High blood pressure is very common too, affecting more than one in four adults in the UK, although many won’t show symptoms and realise it. If untreated, it increases your risk of serious problems including heart disease, the number one killer globally.
The Chinese have used herbs for treating diseases for thousands of years and have become increasingly popular in Europe and North America, mainly as complement to Western medicine. But the researchers also warn that much of the research conducted have limitations and so their long-term effects are not proven.
Herbs for high blood pressure
The blood pressure-lowering effect of herb zhongfujiangya was found to be similar to that of oral anti-hypertension medication benazeprilm, which goes by the brand name Lotensin. Similarly, patients treated for eight weeks with herbal tiankuijiangya had a lower reading than those given a placebo. Herbal Jiangya tablets were found to ‘significantly lower’ systolic blood pressure, that is the amount of pressure in your arteries during contraction of your heart muscle compared to a fake treatment. The herb Jiangyabao also had a significant effect compared to a placebo, but just at night. But overall, compared to the drug Nimodipine, a calcium channel blocker, it worked just as well. Qiqilian capsules also proved more effective compared to a placebo.
Herbs for diabetes
The team report some Chinese medicines medications – such as xiaoke, tangminling, jinlida, and jianyutangkang – have a ‘potent’ effect on lowering blood sugar levels and b-cell function, which controls the release of insulin. Some remedies – such as tangzhiping and tianqi – might prevent the progression of pre-diabetes to diabetes, they note.
Herbs for cholesterol
The researchers looked at research on dyslipidemia, the term for unbalanced or unhealthy cholesterol levels. They found that jiangzhitongluo, salviamiltiorrhiza and pueraria lobata, and zhibitai capsule all have a ‘potent lipid-lowing effect’.
Herbs for heart disease
Some traditional Chinese medicines such as qiliqiangxin, nuanxin, shencaotongmai, and yangxinkang, might be effective in improving function in patients with chronic heart failure, they wrote.
Limitations with trials
But Western scientists often reject Chinese medicine for specific reasons, warned Dr Zhao’s team. Chinese medicines are frowned upon because they do not go through the same exhaustive approval process as trials conducted domestically, they pointed out. Plus, one treatment can be made of many different ingredients with various chemical compounds, making it hard to pinpoint how their benefits work. ‘One should bear in mind that traditional Chinese medicine medications are usually prescribed as complex formulae, which are often further manipulated by the practitioner on a personalized basis,’ said Dr Zhao.

Apart from the fact that this article is badly written, it is also misleading to the point of being outright dangerous. Regular readers of my blog will be aware that Chinese research is everything but reliable; there are practically no Chinese TCM-trials that report negative results. Furthermore, the safety of Chinese herbal preparations is as good as unknown and they are often contaminated with toxic substances as well as adulterated with synthetic drugs. Most of these preparations are also unavailable outside China. Moreover, Chinese herbal treatments are usually individualised (mixtures are tailor-made for each individual patient), and there is no good evidence that this approach is effective. Crucially, the trial evidence is often of such poor quality that it would be a dangerous mistake to trust these findings.
None of these important caveats, it seems, are important enough to get a mention in the Daily Mail.
Don’t let the truth get in the way of a sensational story!
Let’s just for a moment imagine what would happen if people took the Mail article seriously (is there anyone out there who does take the Mail seriously?). In a best case scenario, they would take Chinese herbs in addition to their prescribed medication. This might case plenty of unwanted side-effects and herb-drug interactions. In addition, people would lose a lot of their hard-earned cash. In a worst case scenario, they would abandon their prescribed medication for dubious Chinese herbal mixtures. This could cause thousands of premature deaths.
With just a little research, I managed to find the original article on which the Mail’s report was based. Here is its abstract:
Traditional Chinese medicine (TCM) has more than 2,000 years of history and has gained widespread clinical applications. However, the explicit role of TCM in preventing and treating cardiovascular disease remains unclear due to a lack of sound scientific evidence. Currently available randomized controlled trials on TCM are flawed, with small sample sizes and diverse outcomes, making it difficult to draw definite conclusions about the actual benefits and harms of TCM. Here, we systematically assessed the efficacy and safety of TCM for cardiovascular disease, as well as the pharmacological effects of active TCM ingredients on the cardiovascular system and potential mechanisms. Results indicate that TCM might be used as a complementary and alternative approach to the primary and secondary prevention of cardiovascular disease. However, further rigorously designed randomized controlled trials are warranted to assess the effect of TCM on long-term hard endpoints in patients with cardiovascular disease.
In my view, the authors of this review are grossly over-optimistic in their conclusions (but nowhere near as bad as the Mail journalist). If the trials are of poor quality, as the review-authors admit, no firm conclusions should be permissible about the usefulness of the therapies in question.
As the Mail article is obviously based on a press release (several other papers worldwide reported about the review as well), it seems interesting to note what the editor of the Journal of the American College of Cardiology (the journal that published the review) recently had to say about the responsibility of journalists and researchers:
START OF QUOTE
…I would like to suggest that journalists and researchers must share equally in shouldering the burden of responsibility to improve appropriate communication about basic and clinical research.
First, there is an obligation on the part of the researchers not to inflate the importance of their findings. This has been widely recognized as damaging, especially if bias is introduced in the paper…
Second, researchers should take some responsibility for the creation of the press release about their research, which is written by the media or press relations department at their hospital or society. Press releases are often how members of the media get introduced to a particular study, and these releases can often introduce errors or exaggerations. In fact, British researchers evaluated 462 press releases on biomedical and health-related science issued by 20 leading U.K. universities in 2011, alongside their associated peer-reviewed research papers and the news stories that followed (n = 668). They found that 40% of the press releases contained exaggerated advice, 33% contained exaggerated causal claims, and 36% contained exaggerated inference to humans from animal research. When press releases contained such exaggeration, 58%, 81%, and 86% of news stories, respectively, contained further exaggeration, compared with rates of 17%, 18%, and 10% in the news when the press releases were not exaggerated. Researchers should not be excused from being part of the press release process, as the author(s) should at least review the release before it gets disseminated to the media. I would even encourage researchers to engage in the process at the writing stage and to not allow their hospital’s or society’s public relations department to extrapolate their study’s results. Ultimately, the authors and the journals in which the studies are published will be held accountable for the information that trickles into the headlines, not the public relations departments, so we must make sure that the information is accurate and representative of the study’s actual findings.

Sound advice indeed.
Now we only need to ALL follow it!!!
The current volume of the ‘Allgemeinen Homöopathischen Zeitung’ contains all the abstracts of the ‘Homeopathic World Congress 2017’ which will be hosted in Leipzig, 14-17 July this year by the ‘Deutschen Zentralvereins Homöopathischer Ärzte’ under the patronage of the German Health Secretary, Annette Widmann-Mauz. As not many readers of this blog are likely to be regular readers of this important journal, I have copied six of the more amusing abstracts below:
A male patient with bilateral solid renal mass was investigated and given an individualized homeopathic remedy. Antimonium crudum in 50000 potency was selected after proper case taking and evaluation. Investigations were done before and after treatment. Follow ups took place monthly. Results The patient had symptomatic relief from pain in flanks, acute retention and hematuria. The ultrasonography suggests a reduction in size of both lesions over a period of two years. A small number of lymph nodes of the para-aortic group are still visible. There is a normal level of urea and creatinine, no anemia or hypertention. The patient is surviving since 2014. Conclusion In the present day when malignancies are treated with surgeries, chemo and radiotherapies, homeopathy has a significant role to play as seen in the above case. This case with bilateral solid renal mass, probably a renal cell carcinoma, received an individualized homeopathic remedy-treatment compliant with the totality of symptoms, and permitted the patient to live longer without anemia, hypertension, anorexia or weight loss. The quality of life was maintained without the side effects of surgery, radiotherapy and chemotherapy. Acute retentions, which he used to suffer also remained absent, thereafter. The result of this case suggests to take up further studies on individualized homeopathic treatment in malignant diseases.
Urinary tract infections (UTI) are often a complaint in the homeopathic practice, mainly as uncomplicated infections in the form of a one time event. Some patients, however, have a tendency to develop recurrent or complicated urinary tract infections. Methods It is shown on the basis of case documentation that UTI should be treated homeopathic, variably. The issue of prophylaxis will be discussed. Results If there is a tendency to complicated UTI, chronic treatment after case taking of the symptom-totality of the affected must take place during a free interval. In contrast, the chronically recurring and flaming up of UTI, as well as the uniquely occurring of uncomplicated UTI, are handled as an acute illness. The treatment is based on the striking, characteristic symptoms of the infected. Conclusion The homeopathic treatment of UTI in the acute case of uncomplicated forms is usually very successful, The chronic treatment of complicated UTI shows certain difficulties. A safe homeopathic prophylaxis, in terms of conventional medicine, is problematical.
The homeopathic clinic of the Municipal Public Servant Hospital of São Paulo (HSPM – Brazil) has among patient records some cases of thyroid gland diseases (hypothyroidism or hyperthyroidism), which were treated whith the systemic homeopathic method of Carillo. This study evaluates patients with diseases of thyroid gland, analyzing improvements using a Iodium-like equalizer, adjacent to the systemic medication. The reviewed 21 cases using Iodium equalizer for the disease, adjacent to the systemic medication, in the homeopathic clinic of the HSPM, from 2000 to 2013. In four cases, it was possible to reduce the dose of allopathic medicine and finally terminate it due to normalization of the thyroid gland function. There was one case of hyperthyroidism and it was possible to terminate the use of methimazole. There were four cases, in which the function of the thyroid gland was normalized without the associated use of hormone. In three cases it was possible to reduce the dose of hormone. There were nine cases, in which it was not possible to reduce the dose of the hormone. In cases where there was an improvement applying homeopathic treatment, TSH and free T4 returned to the normal reference value. In cases that were not effective, TSH and free T4 had not normalized. Therefore, the effectiveness of Iodium depends on the ability and stability of the gland thyroid to increase or decrease hormone production, in addition to the treatment of a chronic disease, that affects the thyroid gland.
Cystitis composes infections in the urinary system, especially bladder and urethra. It has multiple causes, but the most common is infection due to microorganisms such as E. coli, streptococcus, staphylococcus etc. If the system is attacked by pathogenetic agents, the defense must include more powerful noxious agents which can fight and destroy the attacking organisms, here is the role of nosodes. Nosodes are the potentised remedies made up from dangerous noxious materials. The use of nosodes in cystitis is based on the aphorism 26– Therapeutic Law of Nature: A weaker one is always distinguished by the stronger one! Colibacillinum, streptococcinum, staphylococcinum, lyssinum, medorrhinum, psorinum and tuberculinum are useful in handling cystitis relating to the organism involved [as found in urine test] and symptom similarity. Method An observational prospective study on a group of 30 people proves the immediate, stronger defensive action of nosodes. Result Amazing! Nosodes given in low potency provided instant relief to patients. Repetition of the same, over several months offered immunity for further attacks of cystitis, as Hering had already testified nosodes have prophylactic action. Conclusion According to law of similia – as per the pathology, as per the defense! By inducing a strong artificial disease, homeopathy can eliminate the natural disease from the body. Usually nosodes are used as intercurrent drugs which play the role of catalysts, on the journey to recovery, but they are also very effective in cystitis as an acute remedy. Acute cystitis is a very troublesome state for the patients, to cure it homeopathy has an arsenal of nosodes.
In 1991, no antiretroviral therapy (ART) treatment was available. The Central Council for Research in Homeopathy had established a clinical research unit at Mumbai for undertaking investigations in HIV/AIDS. So far 2502 cases have been enrolled for homeopathic treatment and three studies have been published since then. In this paper we will highlight the impact of long term homeopathic management of cases, which have been followed up for more than 15 years. Method The HIV positive cases enrolled in different studies are continuously being managed in this unit and even after study conclusion. All the cases are being treated solely with individualised homeopathy. The cases are assessed clinically (body weight, opportunistic infections, etc.) as well as in respect to CD4 counts and CD4/CD8 ratio. Results The CD4 count was maintained in all patients, except in one case. Three patients had the CD4 level in the range of 500–1200, four in the range of 300–500, one had a 272 CD4 count. There has been a decline of CD4/ CD8 ratio since baseline, but the patients have maintained their body weights and remained free from major HIV related illnesses and opportunistic infections. The frequently indicated remedies were pulsatilla pratensis, lycopodium clavatum, nux vomica,tuberculinum bovinum, natrum muriaticum, rhus toxicodendron, medorrhinum, arsenicum album, mercurius solubilis, thuja occidentalis, nitic acid, sulphur, bryonia alba and hepar sulph. Conclusion In the emergent scenario of drug resistance and adverse reactions of ART in HIV infections, there may be a possibility of employing homeopathy as an adjuvant therapy to existing standard ART treatment. Further studies are desirable.
In the last 20 years we have treated in the Clinica St. Croce many patients with cancer. We often deal with palliative states and we aim at pain relief and improvement of life-quality, and if possible a prolongation of life. Is this possible by prescribing a homeopathic therapy? Methodology The exact application and the knowledge of the responses to the Q-potencies often give indications for the correct choice of remedy. Acute conditions of pain often need a more frequent repetition of the C-potencies needed for pain relief. Results Even with severe pain or in so-called final stages homeopathy can offer great assistance. On the basis of case reports from Clinica St. Croce, the procedure for the homeopathic treatment of cancer, and the treatment of pain and final states will be illustrated and clarified. In addition, some clinically proven homeopathic remedies will be presented for the optimal palliation in the treatment of end-states and accompanying the dying. Conclusions With the precise application and knowledge of the responses to the Q- and C-potencies, the homeopathic doctor is given a wonderful helper to treat even the most serious palliative states and can accomplish, sometimes, a miraculous healing.
MY BRIEF COMMENT
These abstracts are truly hilarious and show how totally unaware some homeopaths are of the scientific method. I say ‘some’, but perhaps it is most or even all? How can a scientific committee reviewing these abstracts let them pass and allow the material to be presented at the ‘World Congress’? How can a Health Secretary accept the patronage of such a farce?
These abstracts are therefore not just hilarious but also truly depressing. If we had needed proof that homeopathy has no place in real healthcare of today, these abstracts would go a long way in providing it. To realise that politicians, physicians, patients, consumers, journalists etc. take such infantile nonsense seriously is not just depressing but at the same time worrying, I find.
A recent post discussed a ‘STATE OF THE ART REVIEW’ from the BMJ. When I wrote it, I did not know that there was more to come. It seems that the BMJ is planning an entire series on the state of the art of BS! The new paper certainly looks like it:
Headaches, including primary headaches such as migraine and tension-type headache, are a common clinical problem. Complementary and integrative medicine (CIM), formerly known as complementary and alternative medicine (CAM), uses evidence informed modalities to assist in the health and healing of patients. CIM commonly includes the use of nutrition, movement practices, manual therapy, traditional Chinese medicine, and mind-body strategies. This review summarizes the literature on the use of CIM for primary headache and is based on five meta-analyses, seven systematic reviews, and 34 randomized controlled trials (RCTs). The overall quality of the evidence for CIM in headache management is generally low and occasionally moderate. Available evidence suggests that traditional Chinese medicine including acupuncture, massage, yoga, biofeedback, and meditation have a positive effect on migraine and tension headaches. Spinal manipulation, chiropractic care, some supplements and botanicals, diet alteration, and hydrotherapy may also be beneficial in migraine headache. CIM has not been studied or it is not effective for cluster headache. Further research is needed to determine the most effective role for CIM in patients with headache.
My BS-detector struggled with the following statements:
- integrative medicine (CIM), formerly known as complementary and alternative medicine (CAM) – the fact that CIM is a nonsensical new term has been already mentioned in the previous post;
- evidence informed modalities – another new term! evidence-BASED would be too much? because it would require using standards that do not apply to CIM? double standards promoted by the BMJ, what next?
- CIM commonly includes the use of nutrition – yes, so does any healthcare or indeed life!
- the overall quality of the evidence for CIM in headache management is generally low and occasionally moderate – in this case, no conclusions should be drawn from it (see below);
- evidence suggests that traditional Chinese medicine including acupuncture, massage, yoga, biofeedback, and meditation have a positive effect on migraine and tension headaches – no, it doesn’t (see above)!
- further research is needed to determine the most effective role for CIM in patients with headache – this sentence does not even make the slightest sense to me; have the reviewers of this article been asleep?
And this is just the abstract!
The full text provides enough BS to fertilise many acres of farmland!
Moreover, the article is badly researched, cherry-picked, poorly constructed, devoid of critical input, and poorly written. Is there anything good about it? You tell me – I did not find much!
My BS-detector finally broke when we came to the conclusions:
The use of CIM therapies has the potential to empower patients and help them take an active role in their care. Many CIM modalities, including mind-body therapies, are both self selected and self administered after an education period. This, coupled with patients’ increased desire to incorporate integrative medicine, should prompt healthcare providers to consider and discuss its inclusion in the overall management strategy. Low to moderate quality evidence exists for the effectiveness of some CIM therapies in the management of primary headache. The evidence for and use of CIM is continuously changing so healthcare professionals should direct their patients to reliable and updated resources, such as NCCIH.
WHAT IS HAPPENING TO THE BMJ?
IT USED TO BE A GOOD JOURNAL!
The website of BMJ Clinical Evidence seems to be popular with fans of alternative medicine (FAMs). That sounds like good news: it’s an excellent source, and one can learn a lot about EBM when studying it. But there is a problem: FAMs don’t seem to really study it (alternatively they do not have the power of comprehension to understand the data); they merely pounce on this figure and cite it endlessly:
They interpret it to mean that only 11% of what conventional clinicians do is based on sound evidence. This is water on their mills, because now they feel able to claim:
THE MAJORITY OF WHAT CONVENTIONAL CLINICIANS DO IS NOT EVIDENCE-BASED. SO, WHY DO SO-CALLED RATIONAL THINKERS EXPECT ALTERNATIVE THERAPIES TO BE EVIDENCE-BASED? IF WE NEEDED PROOF THAT THEY ARE HYPOCRITES, HERE IT IS!!!
The question is: are these FAMs correct?
The answer is: no!
They are merely using a logical fallacy (tu quoque); what is worse, they use it based on misunderstanding the actual data summarised in the above figure.
Let’s look at this in a little more detail.
The first thing we need to understand the methodologies used by ‘Clinical Evidence’ and what the different categories in the graph mean. Here is the explanation:
So, arguably the top three categories amounting to 42% signify some evidential support (if we decided to be more rigorous and merely included the two top categories, we would still arrive at 35%). This is not great, but we must remember two things here:
- EBM is fairly new;
- lots of people are working hard to improve the evidence base of medicine so that, in future, these figures will be better (by contrast, in alternative medicine, no similar progress is noticeable).
The second thing that strikes me is that, in alternative medicine, these figures would surely be much, much worse. I am not aware of reliable estimates, but I guess that the percentages might be one dimension smaller.
The third thing to mention is that the figures do not cover the entire spectrum of treatments available today but are based on ~ 3000 selected therapies. It is unclear how they were chosen, presumably the choice is pragmatic and based on the information available. If an up-to date systematic review has been published and provided the necessary information, the therapy was included. This means that the figures include not just mainstream but also plenty of alternative treatments (to the best of my knowledge ‘Clinical Evidence’ makes no distinction between the two). It is thus nonsensical to claim that the data highlight the weakness of the evidence in conventional medicine. It is even possible that the figures would be better, if alternative treatments had been excluded (I estimate that around 2 000 systematic reviews of alternative therapies have been published [I am the author of ~400 of them!]).
The fourth and possibly the most important thing to mention is that the percentage figures in the graph are certainly NOT a reflection of what percentage of treatments used in routine care are based on good evidence. In conventional practice, clinicians would, of course, select where possible those treatments with the best evidence base, while leaving the less well documented ones aside. In other words, they will use the ones in the two top categories much more frequently than those from the other categories.
At this stage, I hear some FAMs say: how does he know that?
Because several studies have been published that investigated this issue in some detail. They have monitored what percentage of interventions used by conventional clinicians in their daily practice are based on good evidence. In 2004, I reviewed these studies; here is the crucial passage from my paper:
“The most conclusive answer comes from a UK survey by Gill et al who retrospectively reviewed 122 consecutive general practice consultations. They found that 81% of the prescribed treatments were based on evidence and 30% were based on randomised controlled trials (RCTs). A similar study conducted in a UK university hospital outpatient department of general medicine arrived at comparable figures; 82% of the interventions were based on evidence, 53% on RCTs. Other relevant data originate from abroad. In Sweden, 84% of internal medicine interventions were based on evidence and 50% on RCTs. In Spain these percentages were 55 and 38%, respectively. Imrie and Ramey pooled a total of 15 studies across all medical disciplines, and found that, on average, 76% of medical treatments are supported by some form of compelling evidence — the lowest was that mentioned above (55%),6 and the highest (97%) was achieved in anaesthesia in Britain. Collectively these data suggest that, in terms of evidence-base, general practice is much better than its reputation.”
My conclusions from all this:
FAMs should study the BMJ Clinical Evidence more thoroughly. If they did, they might comprehend that the claims they tend to make about the data shown there are, in fact, bogus. In addition, they might even learn a thing or two about EBM which might eventually improve the quality of the debate.
The new guidelines by the American College of Physicians entitled ‘Noninvasive Treatments for Acute, Subacute, and Chronic Low Back Pain: A Clinical Practice Guideline From the American College of Physicians’ have already been the subject of the previous post. Today, I want to have a closer look at a small section of these guidelines which, I think, is crucial. It is entitled ‘HARMS OF NONPHARMACOLOGIC THERAPIES’. I have taken the liberty of copying it below:
“Evidence on adverse events from the included RCTs and systematic reviews was limited, and the quality of evidence for all available harms data is low. Harms were poorly reported (if they were reported at all) for most of the interventions.
Low-quality evidence showed no reported harms or serious adverse events associated with tai chi, psychological interventions, multidisciplinary rehabilitation, ultrasound, acupuncture, lumbar support, or traction (9,95,150,170–174). Low-quality evidence showed that when harms were reported for exercise, they were often related to muscle soreness and increased pain, and no serious harms were reported. All reported harms associated with yoga were mild to moderate (119). Low-quality evidence showed that none of the RCTs reported any serious adverse events with massage, although 2 RCTs reported soreness during or after massage therapy (175,176). Adverse events associated with spinal manipulation included muscle soreness or transient increases in pain (134). There were few adverse events reported and no clear differences between MCE and controls. Transcutaneous electrical nerve stimulation was associated with an increased risk for skin site reaction but not serious adverse events (177). Two RCTs (178,179) showed an increased risk for skin flushing with heat compared with no heat or placebo, and no serious adverse events were reported. There were no data on cold therapy. Evidence was insufficient to determine harms of electrical muscle stimulation, LLLT, percutaneous electrical nerve stimulation, interferential therapy, short-wave diathermy, and taping.”
The first thing that strikes me is the brevity of the section. Surely, guidelines of this nature must include a full discussion of the risks of the treatments in question!
The second thing that is noteworthy is the fact that the authors confirm the fact I have been banging on about for years: clinical trials of alternative therapies far too often fail to mention adverse effects. I have often pointed out that the failure to report adverse effects in clinical trials is an unacceptable violation of medical ethics. By contrast, the guideline authors seem not to feel strongly about this omission.
The third thing that is noteworthy is that the guidelines evaluate the harms of the treatments purely on the basis of the adverse effects reported in the clinical trials and systematic reviews included in their efficacy assessments. This is nonsensical for at least two reasons:
- The guideline authors themselves are aware that the trials very often fail to mention adverse effects.
- For any assessment of harm, one has to go far beyond the evidence of clinical trials, because trials tend to be too small to pick up rare adverse effects, and because they are always conducted under optimally controlled conditions where adverse effects are less likely to occur than in real life.
Together, these features of the assessment of harms explain why the guideline authors arrive at conclusions which are oddly misguided; I would even feel that they resemble a white-wash. Here are two of the most overt misjudgements:
- no harms associated with acupuncture,
- only trivial harm associated with spinal manipulations.
The best evidence we have today shows that acupuncture leads to mild adverse effects in about 10% of all cases and is also associated with very severe complications (e.g. pneumothorax, cardiac tamponade, infections, deaths) in an unknown number of patients. More details can be found for instance here, here, here and here.
And the best evidence available shows that spinal manipulation leads to moderately severe adverse effects in ~50% of all cases. In addition, we know of hundreds of cases of very severe complications resulting in stroke, permanent neurological deficits or deaths. More details can be found for instance here, here, here and here.
In the introduction, I stated that this small section of the guidelines is crucial.
The reason is simple: any responsible therapeutic decision has to be based not just on the efficacy of the treatment in question but on its risk/benefit balance. The evidence shows that the risks of some alternative therapies can be considerable, a fact that is almost totally neglected in the guidelines. Therefore, the recommendations of the new guidelines by the American College of Physicians entitled ‘Noninvasive Treatments for Acute, Subacute, and Chronic Low Back Pain: A Clinical Practice Guideline From the American College of Physicians’ are in several aspects not entirely correct and need to be reconsidered.
