Reckitt Benckiser giving a ticking off by the ASA

Reckitt Benckiser, lords of Barry Scott, have been giving a ticking off by the ASA over a Dettol advert. The usual exaggerated claims are too blame.

I want to know why no one ever complains about the other misleading comments in these adverts, namely:

But Dettol Surface Cleanser kills 99.9% of bacteria, including MRSA, E.Coli, salmonella and even the flu virus …

Some of you may now be asking, why is this misleading? It implies that killling MRSA, E. Coli etc. is a difficult thing that maybe other surface cleaners can’t do. The thing is, the vast majority of bacterium and viruses are easily destroyed - soap and hot water will get rid of most, ethanol will get them too, and UV.

Killing these pathogens is not the problem, doing so in an infected patient is. Unfortunately feeding Dettol to a patient with MRSA is unlikely to help them.

The Banished Quackometer Post

Below is the post that has been removed from the Quackometer blog due to “legal reasons” see here and here. Due to it coming from googles cache it’s got some weird html formatting that I’ll sort later. Anyway, enjoy.

Due to the wonders of the blogosphere this has also appeared at the following locations:

The Society of Homeopaths (SoH) are a shambles and a bad joke. It is now over a year since Sense about Science, Simon Singh and the BBC Newsnight programme exposed how it is common practice for high street homeopaths to tell customers that their magic pills can prevent malaria. The Society of Homeopaths have done diddly-squat to stamp out this dangerous practice apart from issue a few ambiguously weasel-worded press statements.

The SoH has a code of practice, but my feeling is that this is just a smokescreen and is widely flouted and that the Society do not care about this. If this is true, then the code of practice is nothing more than a thin veneer used to give authority and credibility to its deluded members. It does nothing more than fool the public into thinking they are dealing with a regulated professional.

As a quick test, I picked a random homeopath with a web site from the SoH register to see if they flouted a couple of important rules:

48 • Advertising shall not contain claims of superiority.
• No advertising may be used which expressly or implicitly claims to cure named diseases.

72 To avoid making claims (whether explicit or implied; orally or in writing) implying cure of any named disease.

The homeopath I picked on is called Julia Wilson and runs a practice from the Leicestershire town of Market Harborough. What I found rather shocked and angered me.

Straight away, we find that Julia M Wilson LCHE, RSHom specialises in asthma and works at a clinic that says,

Many illnesses and disease can be successfully treated using homeopathy, including arthritis, asthma, digestive disorders, emotional and behavioural difficulties, headaches, infertility, skin and sleep problems.

Well, there are a number of named diseases there to start off. She also gives a leaflet that advertises her asthma clinic. The advertising leaflet says,

Conventional medicine is at a loss when it comes to understanding the origin of allergies. … The best that medical research can do is try to keep the symptoms under control. Homeopathy is different, it seeks to address the triggers for asthma and eczema. It is a safe, drug free approach that helps alleviate the flaring of skin and tightening of lungs…

Now, despite the usual homeopathic contradiction of claiming to treat causes not symptoms and then in the next breath saying it can alleviate symptoms, the advert is clearly in breach of the above rule 47 on advertising as it implicitly claims superiority over real medicine and names a disease.

Asthma is estimated to be responsible for 1,500 deaths and 74,000 emergency hospital admissions in the UK each year. It is not a trivial illness that sugar pills ought to be anywhere near. The Cochrane Review says the following about the evidence for asthma and homeopathy,

The review of trials found that the type of homeopathy varied between the studies, that the study designs used in the trials were varied and that no strong evidence existed that usual forms of homeopathy for asthma are effective.

This is not a surprise given that homeopathy is just a ritualised placebo. Hopefully, most parents attending this clinic will have the good sense to go to a real accident and emergency unit in the event of a severe attack and consult their GP about real management of the illness. I would hope that Julia does little harm here.

However, a little more research on her site reveals much more serious concerns. She says on her site that ’she worked in Kenya teaching homeopathy at a college in Nairobi and supporting graduates to set up their own clinics’. Now, we have seen what homeopaths do in Kenya before. It is not treating a little stress and the odd headache. Free from strong UK legislation, these missionary homeopaths make the boldest claims about the deadliest diseases.

A bit of web research shows where Julia was working (picture above). The Abha Light Foundation is a registered NGO in Kenya. It takes mobile homeopathy clinics through the slums of Nairobi and surrounding villages. Its stated aim is to,

introduce Homeopathy and natural medicines as a method of managing HIV/AIDS, TB and malaria in Kenya.

I must admit, I had to pause for breath after reading that. The clinic sells its own homeopathic remedies for ‘treating’ various lethal diseases. Its MalariaX potion,

is a homeopathic preparation for prevention of malaria and treatment of malaria. Suitable for children. For prevention. Only 1 pill each week before entering, during and after leaving malaria risk areas. For treatment. Take 1 pill every 1-3 hours during a malaria attack.

This is nothing short of being totally outrageous. It is a murderous delusion. David Colquhoun has been writing about this wicked scam recently and it is well worth following his blog on the issue.

Let’s remind ourselves what one of the most senior and respected homeopaths in the UK, Dr Peter Fisher of the London Homeopathic Hospital, has to say on this matter.

there is absolutely no reason to think that homeopathy works to prevent malaria and you won’t find that in any textbook or journal of homeopathy so people will get malaria, people may even die of malaria if they follow this advice.

Malaria is a huge killer in Kenya. It is the biggest killer of children under five. The problem is so huge that the reintroduction of DDT is considered as a proven way of reducing deaths. Magic sugar pills and water drops will do nothing. Many of the poorest in Kenya cannot afford real anti-malaria medicine, but offering them insane nonsense as a substitute will not help anyone.

Ironically, the WHO has issued a press release today on cheap ways of reducing child and adult mortality due to malaria. Their trials, conducted in Kenya, of using cheap mosquito nets soaked in insecticide have reduced child deaths by 44% over two years. It says that issuing these nets be the ‘immediate priority’ to governments with a malaria problem. No mention of homeopathy. These results were arrived at by careful trials and observation. Science. We now know that nets work. A lifesaving net costs $5. A bottle of useless homeopathic crap costs $4.50. Both are large amounts for a poor Kenyan, but is their life really worth the 50c saving?

I am sure we are going to hear the usual homeopath bleat that this is just a campaign by Big Pharma to discredit unpatentable homeopathic remedies. Are we to add to the conspiracy Big Net manufacturers too?

It amazes me that to add to all the list of ills and injustices that our rich nations impose on the poor of the world, we have to add the widespread export of our bourgeois and lethal healing fantasies. To make a strong point: if we can introduce laws that allow the arrest of sex tourists on their return to the UK, can we not charge people who travel to Africa to indulge their dangerous healing delusions?

At the very least, we could expect the Society of Homeopaths to try to stamp out this wicked practice? Could we?

Alternative Health Screening: lunacy of lifesaver?

In Mail today, there is a surprisingly sensible article on alternative health screening with a road test to boot.

Prior to trying out this “screenings” the author, Charlotte Dovey, rather more sensibly paid BUPA to screen using conventional methods - blood tests and the like. According to the BUPA Wellwoman Health Assessment (£265 a go):

After the £265 test (okay, that’s not cheap either - but it includes blood checks, lung function and smear tests) I’m told I’m in fine fettle and there is nothing ominous on the horizon. But what will the alternative diagnosticians say?

Ms. Dovey then visited three clinics for three different screenings using the Quantum Xerox machine, the AMI machine and the NES machine. A quick google for these results in very little information apart from the NES machine but I assume that Mario and Yoshi will not be doing the diagnosis.

All these machines seem to work only the principal of measuring electrical fields/energies and there are several mentions of “quantum physics”, “biophysics” and even “yin and yang”. All methods conveniently found that, despite the clean bill of health from BUPA, Ms. Dovey had a rather miserable future ahead with health problems ranging from relatively minor (IBS and anaemia) to some life-threatening and devastating diseases (Alzheimer’s, Parkinson’s, heart and kidney disease).

This is incredibly irresponsible and unethical “health care” and, thankfully, the Mail has reported this rather well with an expert opinion from Dr Graham Archard, vice chairman of the Royal College of General Practitioners, following each “diagnosis” and pointing out the flaws in the diagnoses. Conveniently all of these practitioners also had something to sell to cure these ills from homeopathic remedies and food supplements to acupuncture.

I presume that, unfortunately, such bullshit as these tests are unregulated and, as such, any snake oil selling charlatan or quack can “measure your bodyfield”, concoct a diagnosis and sell you an ineffective cure. Stay well clear.

Nutter claims to have found Maddie’s DNA using GPS

Those lovely, intelligent and witty people over at badscience have directed me to an equally witty story in the Observer. Well I assume it’s supposed to be witty, it certainly had me laughing.

Traces of Madeleine McCann’s body were found on a Portuguese beach weeks after she was reported missing, during tests by a former detective renowned for locating abducted children.

Forensic analysis by retired South African police superintendent Danie Krugel claimed to reveal Madeleine’s body had either been temporarily buried or was still beneath the beach at Praia da Luz, the resort from where she disappeared on 3 May.

Based on a combination of Madeleine’s DNA sample and GPS satellite technology, Krugel’s findings were taken so seriously by Portuguese detectives that officers twice searched the beach.

The ludicrous nature of this device has already been noted by moonflake here, but I’ll go through this story anyway and see what I can add.

Krugel, of the University of Bloemfontein, claims that his technique is able to locate a missing person anywhere in the world using only a single strand of hair.

Now this suggests to me that Krugel holds a scientific position at Bloemfontein, something that may at least give the guy so credence. Unfortunately, it appears that Krugel is actually Head of Security at Central University of Technology in Bloemfontein, hardly the status you’d expect for someone who has potential to be inventor of the century, if it actually works.

Anyway, let’s have a think about the claims of this device and see how it could possibly work.

Apparently the Matter Orientation System (MOS for short) just requires a sample of what you are looking for and it will pinpoint its location, to the accuracy of the GPS one assumes. Even if there is a mechanism for this to work surely it must be extremely susceptible to noise. If one puts in a sample of diamond, as has been claimed before, then surely any one in the surrounding area with a diamond ring/necklane/piercing must be sending the thing nuts. Particularly if it’s supposed to highly sensitive. Equally if, as is claimed, you can just put a hair in it and it’ll find someone based on their DNA it must be one bloody clever device. Not only would it need to extract any DNA from the hair, which would be required to have the follicle attached. It would have to profile it as well other wise it’s going to be very similar to the other people around as well as the chimpanzees in the local zoo.

Possibly the biggest clue to this being pure quackery is the use of the word “quantum”. As Feynman once said, “I think it is safe to say that no one understands quantum mechanics”, a sentiment shared by many physicists and myself. In this day and age the word quantum is only routinely used by the popular media as a catch all to describe things that defy all scientific thinking and rationality. If we don’t know how it works or is plainly ridiculous it must be down to quantum mechanics.

What’s most troubling about this article is not lack of critical thinking by the paper, or the wasted column inches covering such pointless drivel, but the response of the Portuguese police on receiving Krugel’s bullshit evidence.

Krugel’s report of his findings to Portuguese detectives eventually led to British officers being asked to bring in sniffer dogs to supplement the search for Madeleine. The subsequent reaction of the dogs to Kate’s clothing - the so-called scent of death - led to the couple being declared formal suspects over the death of their daughter.

Whether you believe the McCann’s were involved in their daughter’s disappearance or not, the fact the evidence of this charlatan could sway police opinion is frightening. Imagine if such evidence was used in a case of a genuinely guilty person. All the defence would need to is laugh this crap out of court, potentially weakening the prosecution case significantly and calling into question any other evidence submitted.

Update: Ben has blogged about this at bad science

Sugar confusion and some (relatively) sane advice from Holford

There’s a story in in the Mail regarding obesity and sugar consumption. The content in itself is rather dubious, Professor Glenn Gaesser of Univ. of Virginia is claiming that carbohydrates are not fattening but he is part funded by the baking industry. Conflict of interests may arise here I feel.

In the comments we also have some great confusion about what is and isn’t a complex carbohydrate. One comment says:

I’ve limited my carbohydrate intake to complex carbs only (veg and such) and all but eliminated simple carbs (breads, pasta etc) and in the past 6 weeks have lost over 2 stone. Not only that, but I’m less tired, and have had more motivation to exercise and be healthy.

- T. Wolf, Manchester

<pedant>

Complex carbohydrates are things like starch, i.e. polysaccharides, which are found in abundance in bread and pasta. Simple sugars (glucose, fructose) on the other hand are found in “veg and such”.

</pedant>

Most amazingly in this piece is some actually rather sane words everyones favourite pill-peddling media nutritionist Mr Prof. Patrick Holford.

His findings were questioned by British nutritionist Patrick Holford, who said animal studies had shown high-carbohydrate diets “convert rapidly into fat”.

He added: “The old idea was that the way to lose weight was to eat less calories, which is what Gaesser is advocating.

“Gaesser is supporting what has been done for the last 20 years and clearly it’s not working.

“The human body is much more complicated and blood sugar is much more important.”

(emphasis mine)

Yes Patrick, the human is much more complicated which is why some of us would wish you’d leave the health advice to those who are qualified.

Strange contradiction on “Professor” Holfords website

I visited Patrick Holford’s site earlier today and realised a slight contradiction.

Don’t waste money on vitamins!

(image from here)

 

Apparently Patrick doesn’t want us to waste money on vitamins yet on another page we have this lovely image and an advert for his pill-peddling site.

 

Buy Vitamins

(Image from here)

Unfortunately this has left confused about nutrition and as the page linked to is down I’ll have to get my advice from a more reputable source.

Unlucky Gimpy

Within hours of reading Gimpy’s post on dyslexia treatments and the massive quantity of bullshit they are what do I find but an article in the express singing the praises of the Davis Dyslexia Correction Programme

Unlucky Gimpy, looks like you’ll have to put up with the patronising wankers a little longer.

Good old ASA

The ASA have upheld a complaint against Pandith Sri Guru Poojya Vijay Sharmaji, a “psychic” whose advert claimed.

Pandith is an Expert in Astrology with 99% Accurate Results in Palmistry and also Prediction of Horoscope … Born Gifted with Spiritual Powers let him help you to Solve your Problems with his Expert knowledge Yantrik & Mantric” over background graphics of the solar system and tarot cards.

Apparently it failed on a couple of counts, firstly that it

promoted an unacceptable category as defined by rules 3.1 (i) (the occult) and 10. 3 (The occult, psychic practices and exorcism)

and also

Monitoring staff challenged whether Pandith could guarantee 99% accurate results.

I’m surprised he didn’t see it coming.

Welcome and introduction

Hello and welcome to the badchemist blag. This blag has been set up for 2 main reasons: 1) I’ve tried blogging before and thought I’d have another go and 2) BadScienceBlogs is in the process of launching and seemed like a good way to coerce me into blogging/blagging.

So, who is badchemist?

badchemist is (surprisingly) a chemist currently completing his PhD at the University of Durham. My research is in the area of polymer/materials chemistry, particularly controlled radical polymerisation, biomaterials synthesis and the action of alcohol dehydrogenase and what its limits are.

When time permits more details of my research and me will appear here and in the appropriate pages.
