bogus claims

The website of ‘HOMEOPATHY 360’ has just published a new post offering a handy instruction for killing patients suffering from acute appendicitis. If you do not believe me – I don’t blame you, I too found it hard to believe – read this short excerpt advocating homeopathy for this life-threatening condition (for readers without a medical background: if acute appendicitis is not treated promptly, the inflamed appendix might burst, spilling faecal material into the abdominal cavity, resulting in a life-threatening peritonitis):

The post is entitled “A Cure of Acute Appendicitis Using Frequent Homeopathic Doses in Solution

Here is the abstract:

“Placing centesimal potencies in solution and prescribing them frequently for acute conditions is not widely practiced. It can be superior to dry doses in many cases, where a persistent mild medicinal action is preferred to a strong aggravation. By prescribing dissolved doses of Arnica Montana 1m, a case of acute appendicitis was cured quickly. This suggests that centesimal potencies given frequently in solution may be more efficacious, prompt and gentle than treatment with dry doses.”

Fascinating, isn’t it?

Here are more details demonstrating that the author has done his homework:

“When treating a patient with acute medical condi­tion, in certain cases we fail to cure. Even though our case taking, evaluation, analysis, remedy and potency selection seem correct. What is the cause? In the Organon 5th edition (1833) Dr. Hahnemann introduced olfaction and dissolved centesimal remedies as a new method of administering doses. Around the year 1840 Hahnemann began to introduce LM potencies into his practice. From 1840 to 1843 he used both centesimal and LM potencies side by side in medicinal solutions. By these methods he hoped to avoid unwanted aggravations and provide rapid cure.

In some acute cases the aggravation can be discouragingly pro­longed and often cannot be discerned from the patient’s own disease. Many times we change the original prescrip­tion which could very well have been the simillimum. In acute diseases, a dry dose will many times produce an un­necessary aggravation because of the patient’s increased susceptibility. I have much experience now with what I call a “watery dose.” To prepare it, one or two globules of size 10 are diluted in 15ml. of distilled water in which 5 drops of alcohol added with 20 to 30 succussions. From this solution 10 drops are added to another 15 ml of water, and from this solution 5 to 10 drops dose repeated according to the severity of the disease. In such diluted solutions the correct number of drops must be precise. Every time be­fore taking the dose the solution is succussed 5 to 10 times. The same solution can be used for several days or weeks. Hahnemann recommended using carefully measured and dosed solutions with sensitive patients. Many times I have used this method with great success. It is not necessary to take 4 oz. to 8 oz. of water, Just fifteen ml. of distilled water is sufficient. This technique of dosing is also known as a split dose because it uses one or two pills in a solution that is then split over several days or weeks.

The results using this type of dosing can be very dif­ferent from dry doses. There is continuous amelioration of the complaints without aggravation. This comes closer to the ideal of strengthening the weakened vital force than is seen when we simply produce a similar stronger artificial disease in the patient.”

The author also provides a detailed case history of a patient who survived this treatment (of course, without mentioning that acute appendicitis can, in rare cases, have a spontaneous recovery).

MY ADVICE:

I would not recommend Arnica or any other homeopathic remedy for routine use in acute appendicitis (or any other condition) – unless, of course, you want to kill a maximum number of your patients suffering from this medical/surgical emergency.

I am sure you always wanted to know what animal chiropractic is all about!

This website explains it quite well:

START OF QUOTES

…Animal chiropractic (veterinary spinal manipulative therapy) focuses on the preservation and health/wellness of the neuro-musculo-skeletal system. Chiropractic is the science that is centered around the relationship between the spine and the nervous system. The spine is your body’s foundation and the nervous system, including your brain, spinal cord and nerves, controls your entire body. They must work together harmoniously to improve one’s general health and their ability heal. If the systems are not functioning to their highest potential you may experience changes in digestion, heart and lung function, reproduction and most evidently musculature. When adjacent joints are in an abnormal position, called a subluxation, the nervous system and all that it controls will be negatively impacted. If these subluxations are not corrected, they can result in prolonged inappropriate stimulation of nerves. This could result in reduced function internally, musculo-skeletal dysfunction and pain.

Spinal manipulation is the art of restoring full and pain free range of motion to joints and can greatly benefit an animal after they have experienced subluxations. The veterinarian will use their hands to palpate joints both statically and in motion. By doing this, they can determine where the animal is experiencing decreased motion or misaligned joints. Once identified, an adjustment can be performed. An adjustment or spinal manipulation is a gentle, specific, quick and low force thrust that will be applied at an angle specific to the different areas of motion in the spine and extremities. Only a certified animal chiropractor will understand the complexity involved in adjustments and can best assess if an animal can benefit from chiropractic care.

Many animals can benefit from this alternative therapy. If you notice that your animal has a particularly sensitive spot somewhere on their body, is walking or trotting differently and or not performing to the same ability they have previously, they may be a candidate for a chiropractic assessment. However, an animal does not need to be sick or injured to benefit from chiropractic care. Animals in good health or ones used for sporting activities are also prime candidates for chiropractic care. By maintaining your pet’s proper spinal alignment and mobility they will attain optimal function of muscles, nerves and tissues that support the joints. When the body can move freely your pet will experience improved mobility, stance and flexibility, which can evolve into improved agility, endurance and overall performance. Finally, many people have never considered that chiropractic care can also benefit their animal by boosting their immune response. It can aid in providing a healthier metabolism and a vibrant nervous system which all facilitate your animal’s natural ability to heal themselves from within. Chiropractic care can enhance the quality of your pet’s life ensuring many active and healthy years to come.

…during veterinary school I began the process of researching how to become an animal chiropractor or veterinary spinal manipulative therapist. As I researched further, I noticed that this specialized profession has grown. It became apparent that one should be certified by either the College of Animal Chiropractors or American Veterinary Chiropractic Association to practice on animals…  It was surprising to find out that there are only four programs in the USA and Canada that are approved by both organizations. The courses consisted of over 200 hours of intensive study and hands on learning followed by certification testing…

END OF QUOTE

Yes, I did shorten the quote a bit but, rest assured, I did not cut out a single word about the efficacy of animal chiropractic. Even if I had wanted to, I couldn’t: there is no mention of it in the article.

I wonder why!

Looking into Medline, I found several reports related to the subject:

  • One study suggested an association between chiropractic findings in the lumbar vertebrae and urinary incontinence and retention in dogs.
  • A case report highlighted the potential benefits of combining traditional medical management with chiropractic treatment and physical therapy techniques for management of severe acute-onset torticollis in a giraffe.
  • A review explained that there is limited evidence supporting the effectiveness of spinal mobilization and manipulation in animals.
  • An observational study suggested that chiropractic manipulations elicit slight but significant changes in thoracolumbar and pelvic kinematics.
  • A comparative study measured the spinal mechanical nociceptive thresholds in 38 horses, and showed that they increased by 27, 12 and 8% in the chiropractic, massage and phenylbutazone groups, respectively.

… and that was basically it. Not a single study to suggest that chiropractic is effective for specific conditions of animals.

Frustrated, I went on the site of the ‘College of Animal Chiropractic’; surely there I would find the evidence I was looking for. They offer lots of platitudes and this largely nonsensical statement:

“When a joint become restricted in its range of motion(hypomobile or ‘locked-up’), through trauma, repetitive injury, degenerative changes, or structural stresses, the surrounding tissues are affected. This, in turn, further affects the joints ability to move freely and sensitive structures are activated causing the area to be sensitive or painful. Nerves are the communication links between all tissues in the body to the brain and spinal cord; when joint dysfunction is present, messages to other areas are also affected, which can lead to pain, weakness, reduced function, and compensatory changes. Animal chiropractic focuses on the restoration of movement and the promotion of heath by restoring normal joint mechanics and soft-tissue function, thus, normalizing neurological patterns that facilitate healing . The main tool an animal chiropractor uses to restore joint motion is called an “adjustment”, or veterinary spinal manipulation. This gentle, specialized, manual skill, involves the application of a quick, low-force maneuver that is directed to a specific area of a joint at a specific angle. A certified animal chiropractor understands these joint angles intimately and can best asses if an animal can benefit from chiropractic care, and, is the only professional who is qualified to adjust your pet.”

But no evidence!

By now I was desperate. My last hope was the ‘American Veterinary Chiropractic Association’. All I found there, however, was this: the “American Veterinary Chiropractic Association (AVCA) is a professional membership group promoting animal chiropractic to professionals and the public, and acting as the certifying agency for doctors who have undergone post-graduate animal chiropractic training.”

Not a jot of evidence!

The assumption that animal chiropractic is effective seems to rely on the evidence from human studies…

… and we all know how solid that body of evidence is!

My conclusion from all this: chiropractors treating animals and those treating humans have one important characteristic in common.

THEY HAPPILY PROMOTE BOGUS TREATMENTS.

The US ‘FEDERAL TRADE COMMISSION’ has issued an important statement about homeopathic products. The full text with references can be found here; below are a few quotes which I thought were crucial:

“…Homeopathy, which dates back to the late-eighteenth century, is based on the view that disease symptoms can be treated by minute doses of substances that produce similar symptoms when provided in larger doses to healthy people.  Many homeopathic products are diluted to such an extent that they no longer contain detectable levels of the initial substance.  In general, homeopathic product claims are not based on modern scientific methods and are not accepted by modern medical experts, but homeopathy nevertheless has many adherents…

Efficacy and safety claims for homeopathic drugs are held to the same standards as similar claims for non-homeopathic drugs.  As articulated in the Advertising Substantiation Policy Statement, advertisers must have “at least the advertised level of substantiation.”  Absent express or implied reference to a particular level of support, the Commission, in evaluating the types of evidence necessary to substantiate a claim, considers “the type of claim, the product, the consequences of a false claim, the benefits of a truthful claim, the cost of developing substantiation for the claim, and the amount of substantiation experts believe is reasonable.”  For health, safety, or efficacy claims, the FTC has generally required that advertisers possess “competent and reliable scientific evidence,” defined as “tests, analyses, research, or studies that have been conducted and evaluated in an objective manner by qualified persons and [that] are generally accepted in the profession to yield accurate and reliable results.”  In general, for health benefit claims, particularly claims that a product can treat or prevent a disease or its symptoms, the substantiation required has been well-designed human clinical testing.

For the vast majority of OTC homeopathic drugs, the case for efficacy is based solely on traditional homeopathic theories and there are no valid studies using current scientific methods showing the product’s efficacy.  Accordingly, marketing claims that such homeopathic products have a therapeutic effect lack a reasonable basis and are likely misleading in violation of Sections 5 and 12 of the FTC Act.  However, the FTC has long recognized that marketing claims may include additional explanatory information in order to prevent the claims from being misleading.  Accordingly, the promotion of an OTC homeopathic product for an indication that is not substantiated by competent and reliable scientific evidence may not be deceptive if that promotion effectively communicates to consumers that: (1) there is no scientific evidence that the product works and (2) the product’s claims are based only on theories of homeopathy from the 1700s that are not accepted by most modern medical experts.  To be non-misleading, the product and the claims must also comply with requirements for homeopathic products and traditional homeopathic principles.  Of course, adequately substantiated claims for homeopathic products would not require additional explanation.

Perfunctory disclaimers are unlikely to successfully communicate the information necessary to make claims for OTC homeopathic drugs non-misleading.  The Commission notes:

• Any disclosure should stand out and be in close proximity to the efficacy message; to be effective, it may actually need to be incorporated into the efficacy message.

• Marketers should not undercut such qualifications with additional positive statements or consumer endorsements reinforcing a product’s efficacy.

• In light of the inherent contradiction in asserting that a product is effective and also disclosing that there is no scientific evidence for such an assertion, it is possible that depending on how they are presented many of these disclosures will be insufficient to prevent consumer deception.  Marketers are advised to develop extrinsic evidence, such as consumer surveys, to determine the net impressions communicated by their marketing materials.

• The Commission will carefully scrutinize the net impression of OTC homeopathic advertising or other marketing employing disclosures to ensure that it adequately conveys the extremely limited nature of the health claim being asserted.  If, despite a marketer’s disclosures, an ad conveys more substantiation than the marketer has, the marketer will be in violation of the FTC Act.

In summary, there is no basis under the FTC Act to treat OTC homeopathic drugs differently than other health products.  Accordingly, unqualified disease claims made for homeopathic drugs must be substantiated by competent and reliable scientific evidence.  Nevertheless, truthful, nonmisleading, effective disclosure of the basis for an efficacy claim may be possible.  The approach outlined in this Policy Statement is therefore consistent with the First Amendment, and neither limits consumer access to OTC homeopathic products nor conflicts with the FDA’s regulatory scheme.  It would allow a marketer to include an indication for use that is not supported by scientific evidence so long as the marketer effectively communicates the limited basis for the claim in the manner discussed above.”

 

 

Alternative medicine is deeply rooted in the notion of ‘detox’. This website is one of thousands and displays some of the issues in an exemplary fashion:

START OF QUOTES

…There are more than 80,000 chemicals used in the industrialized world. Accumulate enough of these toxins and you might suffer, at the very least, fatigue, headaches, muscle soreness, bloating, depression and, at the worst, chronic disease and cancer… This is why regular detoxification is so important in our modern world. It helps your body eliminate toxic waste stored in your tissues. Plus you’ll get:

  • More energy
  • Stronger immunity
  • Faster fat burning
  • Fewer allergies
  • Fewer aches and pains
  • Healthier skin, hair and nails

You’ll find plenty of detoxification kits – or “detox in a box” – at pharmacies and health-food stores. But there is little if any scientific evidence that any of these quick fixes work. Instead, you’re better off using natural detoxification methods that are safe and reliable. Here’s what I recommend:

Step 1: Live without Toxins

There are many natural ways to rid yourself of toxins to look and feel your best:

  • Limit your exposure to hormones. If you eat grain-fed meat, eat only lean cuts and trim off the fat. If you eat grass-fed beef, it’s okay to eat the fat – it’s good for you.
  • Reduce your intake of caffeine, grains, carbohydrates and sugar. They make it harder for your body to fully process estrogen.
  • Stretch and massage your limbs. This will release acids and toxins stored in your own tissues so your body can eliminate them.
  • Hit the sauna. Perspiring in the heat releases toxins through your skin.

Step 2: Eat Purifying Foods

Did you know there are everyday foods that act as detoxifiers to help your body discard built-up toxins? Foods rich in vitamin C like fruits, berries and fresh vegetables will help do the trick, along with fiber-rich nuts, seeds and grains.

Signs You Need to Detox

  • You have unexplained headaches or back pain
  • You have joint pain or arthritis
  • Your memory is failing
  • You’re depressed or lack energy
  • You have brittle nails and hair
  • You’re suffering from psoriasis
  • You have abnormal body odor, a coated tongue or bad breath
  • You’ve experienced an unexplained weight gain
  • You have frequent allergies

Grapefruit is another food that binds to toxins and helps flush them from your body. It contains a flavonoid called naringenin, a potent antioxidant that decreases your body’s insulin resistance to help prevent diabetes, and reprogram your liver to melt excess fat, instead of storing it.

Why is this important to detoxification? Because toxins tend to collect in the fat around your tissues, like your liver, and eating grapefruit will help you stop this process.

Another food that can help clean out your body is garlic. Garlic increases phagocytosis. This boosts the ability of your white blood cells to fight the effects of toxins in your body.

Eating three cloves of fresh garlic per day will help you detox. If you don’t like the smell of garlic, you can get odorless aged garlic supplements at any health food store.

There’s also chlorella. You can find in most health-food stores, and C. Pyreneidosa is the form with the best metal-absorbing properties.

Most people can tolerate high doses of it with great success. Take 1 gram with breakfast, lunch, and dinner. You can increase the dose to up to 3 grams 3 to 4 times a day.

Another option is fresh cilantro, one of the best detoxifiers for your central nervous system. It mobilizes so much mercury, it can’t always carry it out of the body fast enough. So use it in combination with chlorella.

Eat organic cilantro, make a pesto or tea, or buy a tincture. Take 2 drops 2 times a day before meals or 30 minutes after taking chlorella. Increase your dose to up to 10 drops three times a day.

Step 3: Cleanse Your Internal Organs

Herbs can help clear toxins from your bloodstream, restore liver function and help flush out your kidneys. Detoxifying your liver a couple of times a year can also lower your cholesterol.

Here’s a list of herbal products that work well:

Milk thistle – I recommend 200 mg in capsule form twice a day. Look for dried extract with a minimum of 80 percent silymarin – the liver-cleaning active ingredient.

Alfalfa – This herb has been known to lower cholesterol by 25 percent in lab animals. It’s a good source of protein, vitamins A, D, E, B-6 and K, calcium, magnesium, iron, potassium, trace minerals and digestive enzymes.

Dandelion – This root stimulates bile and acts as a diuretic for excess water. Asians use it to treat hepatitis, jaundice, swelling of the liver, and deficient bile secretion. Use 4-10 grams of the dried leaf or 4 to 10 milliliters (1:1) of fluid extract.

Sarsaparilla – This is one of my favorite teas. It tastes great and acts as an effective blood detox. Native Americans have used it as a restorative tonic for centuries. Use 1-4 grams of the dried root, or 8-12 milliliters (2 to 3 teaspoons) (1:1) liquid extract, or 250 milligrams (4:1) of solid extract.

Burdock Root – This ancient remedy is a diuretic and a diaphoretic. It increases urine and perspiration production by exercising and strengthening these natural purging systems.

Step 4: Cleanse Your Colon

For an effective, natural way to flush out your colon, find and take the following herbs in combination:

  • Cascara Sagrada bark
  • Aloe leaf
  • Marshmallow root
  • Flax seed
  • Rhubarb root
  • Slippery Elm bark

Take them all at once, but be careful not to take too much because you could get some gurgling and it could loosen up your stool. They’re pretty powerful when you use them in this combination.

Step 5: Rid Your Tissues of Heavy Metals

These two compounds will remove chemicals and keep your body clean and pure like it’s supposed to be.

DMSA – This is a compound that removes heavy metal toxins (its real name is meso-2, 3-dimercaptosuccinic acid, but forget that tongue twister… it’s known simply as DMSA).

DMSA has receptor sites that the toxins bind to. The toxins reside inside the cells of the body and DMSA cannot enter the cells. Instead glutathione (your body’s natural toxin remover) residing in the cell pushes the metals out of the cell, where they’re picked up by DMSA and excreted.

DMSA should be taken in on-again/off-again cycles – ideally, three days on and 11 days off because your body needs 11 days to regenerate its glutathione levels.

Activated Charcoal – This is a form of carbon that’s been processed into a fine, black powder. It’s odorless, tasteless, safe to consume and very potent.

In fact, you can take a small amount of charcoal and wipe out decades of toxic heavy metals like arsenic, copper, mercury and lead that have been building up in your body.

You can find activated charcoal in any health-food store. It’s relatively inexpensive and easy to take. Because it’s a powder, you can take it just like you would your favorite protein drink, mixed into a liquid.

Take 20-30 grams a day of powdered activated charcoal (in divided doses) mixed with water over a period of 1-2 weeks.

Step 6: Detoxify Naturally with Citrus Pectin

Modified citrus pectin is made from the inner peel of citrus fruits and is one of the most powerful detoxifying substances I’ve found in the world. It’s also been proven to work in human clinical studies.

In one U.S.D.A. study, scientists gave modified citrus pectin to people for six days and measured the amount of toxins excreted in their urine before taking it and 24 hours after taking it. Here’s what they found:

  • The amount of deadly arsenic excreted increased by 130 percent
  • Toxic mercury excreted increased by 150 percent
  • Cadmium excreted increased by 230 percent
  • Toxic lead excreted increased by 560 percent4

What’s great about modified citrus pectin is that while it eliminates toxic metals and pesticides, it doesn’t deplete your body of zinc, calcium or magnesium. However, consult your physician before taking modified citrus pectin capsules and caplets to make sure they are the kind used in clinical studies and the proper dosage.

END OF QUOTES

This text is so full of unproven notions, disproven theories, implausible assumptions and misunderstood science that I cannot possible address them all here (almost as bad as Prince Charles’ famous ‘detox tincture’). I will therefore only focus on the author’s final CITRUS PECTIN recommendation which apparently is even supported by real evidence. The study cited might have been this one:

This clinical study was performed to determine if the oral administration of modified citrus pectin (MCP) is effective at lowering lead toxicity in the blood of children between the ages of 5 and 12 years. Hospitalized children with a blood serum level greater than 20 microg/dL, as measured by graphite furnace atomic absorption spectrometry (GFAAS), who had not received any form of chelating and/or detoxification medication for 3 months prior were given 15 g of MCP (PectaSol) in 3 divided dosages a day. Blood serum and 24-hour urine excretion collection GFAAS analysis were performed on day 0, day 14, day 21, and day 28.  This study showed a dramatic decrease in blood serum levels of lead (P = .0016; 161% average change) and a dramatic increase in 24-hour urine collection (P = .0007; 132% average change). The need for a gentle, safe heavy metal-chelating agent, especially for children with high environmental chronic exposure, is great. The dramatic results and no observed adverse effects in this pilot study along with previous reports of the safe and effective use of MCP in adults indicate that MCP could be such an agent. Further studies to confirm its benefits are justified.

Apart from the fact that it was published in one of the most notorious altmed journals ever, one ought to mention that it has been rightly criticised for its many and fatal flaws:

• Although the trial was conducted at a university hospital, there is no mention of the study’s approval by an institutional review board  

• The study’s criteria for inclusion and exclusion were not noted.  Although the authors state the MCP product was used for other children not in the study, their results were not included because they did not fit the inclusion criteria. 

• The study had no control/placebo group, although the article states the study was conducted at a hospital that works with lead-poisoned individuals where it is reasonable to assume a group control would be available. 

• Aside from baseline blood levels, only discharge levels were reported.  Presumably, weekly measurements were taken in order to monitor progress and determine when to discharge, but that data was not reported.

There are one or two other human studies on this subject but all of them are of a similar calibre as the one above.

I think this story provides several important lessons:

  • the detox notion is hugely popular in alternative medicine;
  • it is alarmist and takes advantage of our fear to get poisoned by modern life;
  • it is packaged into sciency language in order to appear plausible to lay people;
  • one hardly needs to scratch the surface to find that the ‘science’ is, in fact, pseudoscience of the worst kind;
  • alternative detox thus turns out to be little more than a cunning but dishonest and unethical sales pitch.

If your life-style is unhealthy, don’t think that detox will help, but change your ways.

If the air that you breathe or the water that you drink are polluted, don’t think that detox is the solution, but punish the government that is responsible for these disasters and vote for someone more responsible.

Detox, as used in alternative medicine, is stupid, unethical nonsense promoted by charlatans of the worst kind; don’t fall for it!!!

The fact that some alternative medicine (the authors use the abbreviation ‘CAM’) practitioners recommend against vaccination is well-known and often-documented. Specifically implicated are:

As a result, children consulting homeopaths, naturopaths or chiropractors are less likely to receive vaccines and more likely to get vaccine-preventable diseases. These effects have been noted for several childhood infections but little is known about how child CAM-usage affects influenza vaccination.

A new nationally representative study fills this gap; it analysed ∼9000 children from the Child Complementary and Alternative Medicine File of the 2012 National Health Interview Survey. Adjusting for health services use factors, it examined influenza vaccination odds by ever using major CAM domains: (1) alternative medical systems (AMS; eg, acupuncture); (2) biologically-based therapies, excluding multivitamins/multi-minerals (eg, herbal supplements); (3) multi-vitamins/multi-minerals; (4) manipulative and body-based therapies (MBBT; eg, chiropractic manipulation); and (5) mind-body therapies (eg, yoga).

Influenza vaccination uptake was lower among children ever (versus never) using AMS (33% vs 43%; P = .008) or MBBT (35% vs 43%; P = .002) but higher by using multivitamins/multiminerals (45% vs 39%; P < .001). In multivariate analyses, multivitamin/multimineral use lost significance, but children ever (versus never) using any AMS or MBBT had lower uptake (respective odds ratios: 0.61 [95% confidence interval: 0.44-0.85]; and 0.74 [0.58-0.94]).

The authors concluded that children who have ever used certain CAM domains that may require contact with vaccine-hesitant CAM practitioners are vulnerable to lower annual uptake of influenza vaccination. Opportunity exists for US public health, policy, and medical professionals to improve child health by better engaging parents of children using particular domains of CAM and CAM practitioners advising them.

There is hardly any need to point out that CAM-use is associated with low vaccination-uptake. We have discussed this on my blog ad nauseam – see for instance here, here, here and here. Too many CAM practitioners have an irrational view of vaccinations and advise against their patients against them. Anyone who needs more information might find it right here by searching this blog. Anyone claiming that this is all my exaggeration might look at these papers, for instance, which have nothing to do with me (there are plenty more for those who are willing to conduct a Medline search):

  • Lehrke P, Nuebling M, Hofmann F, Stoessel U. Attitudes of homeopathic physicians towards vaccination. Vaccine. 2001;19:4859–4864. doi: 10.1016/S0264-410X(01)00180-3. [PubMed]
  • Halper J, Berger LR. Naturopaths and childhood immunizations: Heterodoxy among the unorthodox. Pediatrics. 1981;68:407–410. [PubMed]
  • Colley F, Haas M. Attitudes on immunization: A survey of American chiropractors. Journal of Manipulative and Physiological Therapeutics. 1994;17:584–590. [PubMed]

One could, of course, argue about the value of influenza vaccination for kids, but the more important point is that CAM practitioners tend to be against ANY immunisation. And the even bigger point is that many of them issue advice that is against conventional treatments of proven efficacy.

In a previous post I asked the question ‘Alternative medicine for kids: when is it child-abuse?’ I think that evidence like the one reported here renders this question all the more acute.

How often have I pointed out that most studies of chiropractic (and other alternative therapies) are overtly unethical because they fail to report adverse events? And if you think this is merely my opinion, you are mistaken. This new analysis by a team of chiropractors aimed to describe the extent of adverse events reporting in published RCTs of Spinal Manipulative Therapy (SMT), and to determine whether the quality of reporting has improved since publication of the 2010 Consolidated Standards Of Reporting Trials (CONSORT) statement.

The Physiotherapy Evidence Database and the Cochrane Central Register of Controlled Trials were searched for RCTs involving SMT. Domains of interest included classifications of adverse events, completeness of adverse events reporting, nomenclature used to describe the events, methodological quality of the study, and details of the publishing journal. Data were analysed using descriptive statistics. Frequencies and proportions of trials reporting on each of the specified domains above were calculated. Differences in proportions between pre- and post-CONSORT trials were calculated with 95% confidence intervals using standard methods, and statistical comparisons were analysed using tests for equality of proportions with continuity correction.

Of 7,398 records identified in the electronic searches, 368 articles were eligible for inclusion in this review. Adverse events were reported in 140 (38.0%) articles. There was a significant increase in the reporting of adverse events post-CONSORT (p=.001). There were two major adverse events reported (0.3%). Only 22 articles (15.7%) reported on adverse events in the abstract. There were no differences in reporting of adverse events post-CONSORT for any of the chosen parameters.

The authors concluded that although there has been an increase in reporting adverse events since the introduction of the 2010 CONSORT guidelines, the current level should be seen as inadequate and unacceptable. We recommend that authors adhere to the CONSORT statement when reporting adverse events associated with RCTs that involve SMT.

We conducted a very similar analysis back in 2012. Specifically, we evaluated all 60 RCTs of chiropractic SMT published between 2000 and 2011 and found that 29 of them did not mention adverse effects at all. Sixteen RCTs reported that no adverse effects had occurred (which I find hard to believe since reliable data show that about 50% of patients experience adverse effects after consulting a chiropractor). Complete information on incidence, severity, duration, frequency and method of reporting of adverse effects was included in only one RCT. Conflicts of interests were not mentioned by the majority of authors. Our conclusion was that adverse effects are poorly reported in recent RCTs of chiropractic manipulations.

The new paper suggests that the situation has improved a little, yet it is still wholly unacceptable. To conduct a clinical trial and fail to mention adverse effects is not, as the authors of the new article suggest, against current guidelines; it is a clear and flagrant violation of medical ethics. I blame the authors of such papers, the reviewers and the journal editors for behaving dishonourably and urge them to get their act together.

The effects of such non-reporting are obvious: anyone looking at the evidence (for instance via systematic reviews) will get a false-positive impression of the safety of SMT. Consequently, chiropractors are able to claim that very few adverse effects have been reported in the literature, therefore our hallmark therapy SMT is demonstrably safe. Those who claim otherwise are quite simply alarmist.

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:

  1. The guideline authors themselves are aware that the trials very often fail to mention adverse effects.
  2. 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.

Why?

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.

It has been pointed out that many of the discussions we have on this blog are like pigeon chess. The term comes from a comment made by Scott D. Weitzenhoffer about Evolution vs. Creationism: An introduction: “Debating creationists on the topic of evolution is rather like trying to play chess with a pigeon — it knocks the pieces over, craps on the board, and flies back to its flock to claim victory.”

Debating a fan of alternative medicine is frequently just like that: ignorant of the basics of science and logic, he nevertheless insists on playing with you, knocks over the pieces, defecates on the board, flies back to his flock to boast of victory, only to come back a little later to start over again.

The sequence of events is comically stereotypical: in order to start this game, the evangelist of alternative medicine does his best to appear rational and interested in the subject. Once a discussion has commenced, he begins to make more and more irrational claims. When asked to provide evidence for them, he evades the challenge. Instead, he issues all sorts of accusations to you. Some of the favourites include:

  • being not competent to discuss the issue at hand,
  • having a closed mind,
  • being paid by BIG PHARMA,

As the accusations continue, it can be almost impossible to remain polite. Your reminders to produce evidence for the evangelist’s irrational claims become more and more pressing. He then decides to focus on a triviality and pesters you with questions about it which are too silly to answer. Consequently, the temperature of the exchange rises until his accusations become offensive or turn into overt insults (in the past I have sometimes deleted insulting comments and I intend to continue doing this on hopefully rare occasions). The aims of the evangelist are 1) to arrive at a point where you lose your temper and 2) to distract from the fact that he is unable to provide any evidence for his outlandish claims. Eventually your patience is exhausted and you finally start paying him back in the same coinage as he dispensed.

At this stage, the evangelist indignantly shouts:

  • YOU HAVE INSULTED ME!!!
  • YOU HAVE INSULTED ANYONE WHO DISAGREES WITH YOU!!!
  • THIS SHOWS WHAT A BAD, BAD PERSON YOU ARE!!!

Consequently, you give him a real piece of your mind and tell him what you really think of people who are belligerent,  ignorant on their chosen subject, provocatively irrational and unable or unwilling to learn. The reaction of the evangelist is predictable: he says THAT’S IT, I AM NOT TALKING TO YOU ANYMORE, announces that he is the winner of the argument, and flies off triumphantly promising never to return.

Finally!

We all give a sigh of relief. The evangelist has now returned to his fellow conspiracy theorists where he defames you the best he can. Eventually he disappoints your hope of peace and rationality by returning to the table. He pretends nothing has happened and starts over again.

So, what is the solution?

I am not sure there is an ideal way out.

Personally I intend to do the following in future (and I invite others to follow my example): before I reach the point where I lose my temper completely and regrettably, I will refer the evangelist to this blog post entitled ‘A method of ending discussions with belligerent twits’. At the same time, I will inform him (rarely it is a ‘her’) that I am about to break off the discussion with him because I fear that otherwise I might be openly rude, and perhaps even tell him: YOU ARE A FLAMING IDIOT WHO POSTS FAR TO MUCH NONSENSE TO BE TAKEN SERIOUSLY.

This, I hope will get my message across without actually ever tempting me to post a rude word again.

Failing this, I will block him completely, a measure to which so far I only needed rarely to resort.
