Stuff that occurs to me

All of my 'how to' posts are tagged here. The most popular posts are about blocking and private accounts on Twitter, also the science communication jobs list. None of the science or medical information I might post to this blog should be taken as medical advice (I'm not medically trained).

Think of this blog as a sort of nursery for my half-baked ideas hence 'stuff that occurs to me'.

One of those test posts by email

Not sure about the wisdom of being able to email in blog posts but testing the system.

Mophie batteries (part one)

I love my Mophie Juice pack which adds extra battery oomph to my iPhone.

There are two kinds that I'm aware of:- Mophie Juice pack and Mophie Juice pack Air, both available from http://www.mophieuk.com/ or 0845 619 0845.

Mophie's battery page is at http://www.mophieuk.com/index.php/batteries.html, the relevant batteries are the first and fourth in the picture grid (of four batteries shown)

Mophie Juice pack Air is currently £64.99
Mophie Juice pack is currently £69.49

Compared below (the text is pinched from their website which I will of course remove if this irks Mophie).

What sold the Juice pack for me was the oomphed 3G time for iphone 3Gs, having been to several conferences where the wifi signal was somewhat feeble - having said that there's no guarantee that you'll get a good 3G signal. But I can watch videos / listen to podcasts for longer too. Mind you, in areas of guaranteed wifi the Juice pack Air might be the better bet, but doesn't last as long for non-internet things.

My Mophie Juice Pack for 3G - the picture on the left is the actual battery, and the metal bit at the moment clips into the phone's socket so that the battery envelopes the phone. The photo on the right shows the unopened battery - there's a tiny button on the back that lets you check how charged up it is. Presumably it ships 3/4 full (there are four blue LEDs, three are lit below).
It's gorgeous :)

Thoughts on collating blog posts on bad health topics

Yes... this is another idea from me on aggregating things....

There are many blogs which cover general areas of bad science / health reporting, but this post refers more to those which look at a discrete topic such as reflexology, iridology, homeopathy, ear candling etc.

It's quite easy to do a literature review in PubMed and other databases. It's not impossible to do a blogerature review in Google but it's not as easy as that database includes a whole load of other pages with plenty of the same keywords, but no "Filter by bad science" option.

There are some blogs that are linked - eg scienceblogs - which I believe you can search en masse (I might be wrong about this in fact) but that of course would only include the linked, and not the independent, blogs. Possibly the fact that they are linked also adds in a layer of quality control (in that they get to be linked) - I'm not sure.

My suggestion is that a meta-list of blog posts, themed by topic, isn't a bad idea - and one that everyone could add to. I've no idea how to make this work, also others might think it's a crap idea! Also it could be quite a palaver to set up and maintain - this is me thinking aloud.

I'm not particularly bothered about people retreading a topic previously written about - always plenty of new things to say on many topics - but many of the science bloggers will have, by virtue of their diligent approach, done some of the groundwork in finding some relevant references and it's perhaps useful to come across this when tackling the subject again.

At the moment if I want to find out who's written on a topic I can throw myself on the mercy of Google or ask my science blogger chums on Twitter. Both pretty good but for someone wanting to read more about an area who doesn't know some of the science bloggers, or the actual blogs themselves, or who wishes Google had a bad science filter my idea might help.

Fun with iridology

Shortened link for this post is http://is.gd/zQcjFk

EDIT: 4 June 2011 - I've added at the end the text from the complaint I've just made about iridology claims on http://www.livebloodtest.com

A local shop, full of undoubtedly kindly hearted people, sells iridology as a diagnostic tool.

"Iridology
Is a diagnostic science which studies the iris of the eye to gain information about the body. Genetic strengths and weaknesses, levels of inflammation and toxaemia, efficiency of the immune and eliminative systems can all be read here."

Further reading (admittedly Wikipedia mostly) suggests the idea that all the organs of the body map onto the iris so that examination of the iris/irises (actually I think it's irides) could tell you about ailments in the various organs. I think this is nonsense. I think the Wikipedia authors do too.

But I have some homework to do on this I think... this is a sort of 'draft post' while I collect some information and check a few things... no rush :)

1. Genetic strengths and weaknesses
I don't doubt that the appearance of the iris is related to a person's genes - heredity plays a role in pigmentation for starters; there are other genetic conditions affecting the iris, for example aniridia.

If someone is born with an error in another organ of the body I can't see any reason why this information would already be available as a marker in the iris... but I suppose I should check!

The iris doesn't appear to change much throughout life so if some other change happens to an organ in the body, during life, it's probably not being reflected in any changes to the iris.

2. Levels of inflammation
They might have a point on this one, provided they limit it to anterior uveitis also known as iritis, which is an autoimmune inflammation of the iris. It affects the whole iris, rather than just a discrete patch of it. Judging from photos on the internet you perhaps wouldn't need to be an iridologist to spot some of the cases...

Possibly there are other inflammatory conditions of the eye but with eye problems I think you can usually tell just by looking at the eye rather than focusing on the iris.

3. Toxaemia
Well I suppose... but I don't think it would be specific to the iris. There are perhaps better clues for toxaemia which in my book means blood poisoning.

4. Efficiency of the immune system
Struggling to see how the iris could tell you much about this. If the iris is inflamed then white blood cells may well be doing their immune 'thing; so at a stretch you could glean some information about the immune system's efficiency. But you can't do this just by looking at the iris, I think some fancy lamps are involved and more high tech equipment.

5. Eliminative systems
Well I think we might be on to something here. Unfortunately I've found only one example - the deposition and buildup of copper in the outer surface of the eye leading to Kayser-Fleischer rings around the iris. This is apparently a sign of Wilson's disease which arises because of a problem with the liver's ability to handle copper.

I don't consider this to be much evidence in favour of iridology though because, again, it affects the whole iris and is not restricted to a particular "liver" section of the iris wherever that might be.

The kidney is also an eliminative system but iridology seems to be useless in detecting problems here...
Ernst, E (2000) Iridology: not useful and potentially harmful. Arch Ophthalmol, 118: 120-121.

------ Other things to consider -------

6. Evidence that iridologists can detect illness from irises
It's not looking good. Asking iridologists to look at people who have a health condition and healthy controls (without knowing who's healthy or not, or what condition they have) results in diagnoses that are no better than chance, or missed diagnoses - false positives and false negatives as well as some 'hits'. Not reliable, not much of a diagnostic tool.

The studies I've found gave iridologists photographs of the eye. I can imagine that in a real world situation an iridologist would see the whole person before looking at their eye, affording plenty of opportunity for cold or hot reading (let's face it you can make some educated guesses about a person's health just by looking at them, perhaps combined with comments made by the person about their health, or their responses to questions or comments).

Of course, if the patient were visiting a doctor then this sort of information would be available to them too, but who has the better record in spotting problems I wonder...

Representation at a distance
The idea of a 'record' of a diseased organ showing up in a different organ - is there a term for that? The concept also crops up in reflexology, a little in palm reading, phrenology to a certain extent - and rumpology (or asstrology).

Can iridologists tell you any information about the health of the eyes?
Let alone any hope of spotting problems in other organs, can iridologists diagnose iritis, Wilson's disease as well as glaucoma, macular degenerative disorders, retinopathy etc.?


--------------------- ASA complaint text --------------------

Dear ASA 

This is a new complaint about claims made about iridology on one of the Fitalifestyle Ltd websites - Live Blood Test. Having looked into the evidence myself I'm certain that it's lacking for all of the claims made. Bizarrely some conditions (cataracts, Wilson disease, uveitis) actually can be detected from looking at the eyes or irises (though other confirming tests might be needed) yet these are mentioned nowhere on the pages. 

All of the following claims were collected from http://www.livebloodtest.com/iridology.php

1. "with the iris revealing information about your entire body"This is untrue. There is no mapping between the iris and the body and I think it's misleading to suggest that the iris can reveal any information about 'your entire body'. Iridology is a bogus diagnostic test.
 
2. "reliable way of obtaining a ‘snapshot’ of your health"As above, it isn't reliable. Appropriate blood tests (not the ones on sale here where blood is viewed under a microscope) and other genuine diagnostic tests can give more accurate and relevant information. 

3. "An iris analysis is a preventative tool offering many benefits"It is not, and cannot prevent disease.

4. "Learning about and understanding your genetic constitution will help you resolve or even prevent chronic health problems, including allergies, arthritis, diabetes, eczema, high blood pressure, fatigue, hormonal imbalances, and many others"By itself this is marginally true - genetic counselling is available for many conditions and knowing your family history for disease risk can change behaviour (unlikely to help 'resolve' conditions though). 

However in the context of this page, the claim follows a sentence about iridology and I can't help concluding that the intention is to imply that iridology is somehow able to give health information about any of the diseases listed, prevent them or 'resolve' them. That's not true. 

5. "After your irises are analysed, you will be given a detailed personalised iridology report with the following information:
· Your genetic iris make-up, including any pre-dispositions to diseases and potential health challenges
· Any inefficient organs and systems in the right and left side of your body
· Nutrition recommendations and lifestyle advice beneficial for your genetic iris type and/or any weakened organ areas."
'genetic iris make up' is pretty meaningless - clearly the colour of the iris has a genetic cause but that's pretty much it. 

Virtually no information can be gleaned about inefficient organs or systems unless the person's irises contain 'Kayser-Fleischer' rings around the iris which indicate Wilson's disease (which is an inherited disorder). This is a condition in which the liver is less able to process copper and this is instead deposited in other tissues including the iris. The rings appear around the whole iris and are not restricted to a particular area, for example an area that is believed to map to the liver. 

Anterior uveitis / iritis can also be seen, an inflammation of the iris and eye can be clearly seen in a photograph of an eye, or the 'live' eye, however neither Wilson disease nor uveitis / iritis are mentioned as conditions that can be detected. From a quick Google the signs seem so obvious that to be honest I think I could probably have a sporting chance of detecting them. 

I do not believe that there is any relevant nutritional recommendation that could be made following an iridology test for the conditions listed. The bit about 'genetic iris type' and 'weakened organ areas' is nonsense. To be fair, if Wilson disease was picked up then the patient would be given nutritional advice as it’s recommended that they avoid high copper-containing foods, such as shellfish or liver. However drug treatment for this condition is apparently necessary as well.

6. "iridology serves as a wonderful adjunct to nutritional microscopy live blood testing"This implies that nutritional microscopy is something other than nonsense. I have already had an adjudication upheld against Fitalifestyle Ltd's claims made about nutritional microscopy on their 'Live Blood Test' analysis leaflet, and a complaint about similar claims on the http://www.livebloodtest.com website is currently under ASA investigation. Both iridology and nutritional microscopy lack evidence for the claims made. 

7. "It not only complements but also enhances and confirms the findings of live blood analysis by providing supporting evidence"~Again, no. 

Claims 8 and 9 are combined. Claim 9 comes from http://www.livebloodtest.com/iridology.php?gid=2
8. "we are able to offer an online iridology service. All you need to do is email us a clear digital image (in JPEG format) of your right and left iris"
9. "Cost £120 payment needs to be paid before detailed report is sent"£120 is an incredible amount of money to charge for something that cannot possibly give you any useful information about your health. 

I'm pretty sure that genuine registered doctors would be in serious trouble if they withheld important information from patients based on a lack of payment. However, since no important information can be gleaned from iridology analysis I'll restrict my complaint to amazement at the price charged for this nonsense.

All the applications I've ever blocked on Facebook

I hadn't realised that Facebook kept a list of all the applications I've blocked, but of course - when you think about it - they'd have to. Since I discovered that whenever a friend adds an application it immediately can see whatever my friend sees (ie, pretty much everything) I've made sure that I block them and limit what they can see. Because I use the basic applications (links, groups, notes, photos) I can't eliminate what applications see entirely.

Facebook's great and I can't really complain about having information on the internet, but it's the principle of the thing ;)

So... here are all the apps I've blocked.
