The latest British insanity

New safety rule for firefighters: stay off that ladder

Firefighters on Humberside have been told by their employers that it is dangerous for them to go up ladders. Given that going up ladders to rescue people from blazing buildings is what firefighters do for a living, the news has been greeted with more than a spark of incredulity by the individuals who man the fire service for Hull and its surrounding area.

But it is not sending up extending ladders on the back of fire engines to deal with towering infernos that is causing concern. It is climbing mere stepladders to install smoke alarms in people’s homes, a popular prevention measure offered free by the Humberside Fire and Rescue Service. The brigade is reviewing its stepladder policy after local officials of the Fire Brigades Union pointed out that a firefighter on a stepladder not much more than 6ft from the floor may be contravening the Health and Safety Executive Work at Height Regulations 2005. Fire officials are considering whether to insist that crews who install alarms should work on a platform rather a ladder. Glenn Ramsden, a spokesman, said: “The fire service, just like any other organisation, is not exempt from health and safety legislation.”

Sean Starbuck, regional chairman of the FBU, said: “The use of stepladders to fit smoke alarms contravenes working-at-height regulations, which were introduced by the Government. We have raised the issue and the Health and Safety Executive has agreed that a review is needed.”

One firefighter, who asked not to be named, said: “Is it me, or is this an example of health and safety gone mad?” Another said: “Where will this end? Will we still be able to carry a rescued person down a ladder, or enter a burning building, without the HSE on our back?” The HSE regulations, introduced two years ago, state that employers must select the most suitable equipment for working at height and ensure that protection measures are in place.

Humberside firefighters have installed about 15,000 smoke alarms in private homes over the past year and the brigade emphasised yesterday that its service would continue. No decision has been taken yet on the safest way for its staff to reach people’s ceilings.

The Royal Society for the Prevention of Accidents says that about 40,000 people a year end up in hospital after ladder-related accidents. A spokeswoman added: “If used correctly, ladders are still a much safer way of working at height than standing on household items.” No figures are available for the number of firefighters who have been injured in falls from stepladders.


The anti-MMR gravy train derailed

Revealed: How more than £15million of legal aid funding was spent by lawyers trying and failing to prove that the MMR vaccination causes autism.

Five years ago, supporters of Dr Andrew Wakefield’s claim of a link between the MMR vaccine and autism used to argue that ‘the evidence was stacking up’ in support of this theory. In fact, the only evidence that was stacking up was evidence against the link: more recently a series of robust epidemiological studies showing no reason to suspect that MMR caused autism has been supplemented by rigorous virological investigations failing to demonstrate any link (1, 2). Meanwhile, another stack of evidence has emerged, revealing how legal aid funding bankrolled the campaign against MMR.

Two significant developments occurred over the Christmas period in the long-running MMR saga – both related to the activities of the investigative journalist Brian Deer. It was Deer who, in The Sunday Times in February 2004, first exposed Dr Wakefield’s failure to disclose the conflict of interest arising from legal aid funding for the study published in the Lancet in February 1998 that launched the MMR-autism scare. In a subsequent ‘Dispatches’ documentary broadcast by Channel 4 in November 2004, Deer raised further questions about Dr Wakefield’s funding and about the ethical conduct of his research (as well as revealing his association with quacks and charlatans in the USA).

On 22 December 2006, in response to a request initiated by Deer under the Freedom of Information Act, the Legal Services Commission revealed for the first time details of how more than £15million of legal aid funding was spent by lawyers attempting to make a case that MMR had caused autism in more than 1,000 children (3). This case collapsed in September 2003 when the LSC finally realised that there was no possibility of the case succeeding on the basis of the research commissioned by the lawyers and refused further funding. On 2 January this year, Dr Wakefield announced his withdrawal from the libel action he had launched against Deer and Channel 4 over the ‘Dispatches’ programme, agreeing to pay costs of £500,000 (borne by Dr Wakefield’s medical insurance firm) (4). Let’s look first at the libel debacle.

Dr Wakefield’s abandonment of his claim that Deer’s documentary had misrepresented him follows earlier setbacks in the progress of his libel action (5). In November 2005, Justice Eady refused an attempt by Dr Wakefield’s team to postpone the hearing of his libel claim until after his appearance before the General Medical Council, on associated disciplinary charges (for my view on Dr Wakefield’s appearance at the GMC see Stop witch-hunting Wakefield). The judge was highly critical of what he described as Dr Wakefield’s wish ‘to use the existence of libel proceedings for public relations purposes, and to deter other critics’ while trying to delay the case, thus denying Deer the opportunity to defend himself. Dr Wakefield had tried to take advantage of his ongoing libel claim to deter critical commentary on the case in the press, on the radio, even on the Department of Health’s website.

In November and December 2006, Justice Eady made further rulings allowing Deer’s application to see copies of key documents – including clinical records of children involved in the Lancet study and other documents that Dr Wakefield had been required to make available to the GMC investigation. The fact that Dr Wakefield’s withdrawal from the libel action followed so closely on Deer’s team gaining access to these documents suggests that they were supportive of Deer’s case.

One unfortunate aspect of the collapse of the libel action is that this information will remain secret – at least until Dr Wakefield’s appearance before the GMC (now scheduled for July). Nevertheless, Dr Wakefield’s libel volte face is a dramatic vindication of Deer and his carefully documented exposure of the anti-MMR campaign.

The LSC’s disclosures confirm that the major beneficiaries of the anti-MMR litigation (payments were made from 1992 up to 2004) were the lawyers. They received some two thirds of the £15million total (£8million to solicitors, £1.7million to barristers). The bulk of the revenues accruing to solicitors went to the Manchester-based firm Alexander Harris, where one partner, Richard Barr, played the leading role in coordinating the anti-MMR campaign from the outset. Barr also pursued the claims of alleged victims of the use of organophosphates in farming and of former soldiers with Gulf War syndrome (with equal lack of success). He has subsequently left Alexander Harris and has apparently abandoned the anti-MMR cause.

The LSC provides a detailed account of how a further £4.2million was claimed in ‘fees and expenses’ by more than 60 experts retained by the lawyers in the quest to justify their claim for damages against the vaccine manufacturers by proving a link between MMR and autism. The key payments – amounting to a total of nearly £1.7million - went to around a dozen prominent campaign supporters (6). In principle, expert witnesses are supposed to provide objective evidence to the courts. In practice, it is clear that, in the case of the anti-MMR litigation, legal aid funding went largely to those supportive of the anti-MMR campaign.

The notion that serious science could result from research sponsored by legal aid funding and administered by lawyers is nonsense. The team of experts assembled by Barr did not include a single recognised autism specialist, paediatrician, vaccine specialist, virologist or paediatric gastroenterologist who has a current public appointment or is currently in practice. (Indeed, many of the experts have long retired, though several have embarked on new careers as professional expert witnesses.) When the LSC finally called a halt to the litigation in September 2003, it belatedly acknowledged that ‘in retrospect, it was not effective or appropriate for the LSC to fund research’, conceding that ‘the courts are not the place to prove new medical truths’ (7).

To any observer not familiar with the world of law, what is striking is the sheer scale of the payments received by the witnesses in this case, which contrasts sharply with standard incomes in the medical and scientific world. To enable a rough comparison, in the UK in the 1990s, the basic income of a mid-career researcher at a university or medical school would have been around £50,000 to £60,000 a year; a clinical psychologist would earn perhaps £30,000 to £40,000. What emerges is a cultural gulf between the largely public sector worlds of medicine and science, on the one hand – with low incomes, austere working conditions, meetings in shabby hospital or university seminar rooms, with institutional tea and sandwiches – and, on the other hand, the glitzy world of the law, in which highly paid professionals meet in luxury hotels with lavish hospitality and everybody claims handsome expenses (and after some quibbling, the LSC pays up).

Dr Wakefield received a total of more than £400,000 for his contribution to the case (equivalent to several times his annual income in the 1990s). He claims that he charged at the rates recommended by the British Medical Association for such work (between £47 and £100 per hour) (8). If he worked full time at this rate, his receipts would cover between two and four years exclusively devoted to the case. (Indeed, he indicates that his final award from the LSC was £100,000 less than he claimed.) Yet he was employed by the Royal Free up to December 2001, when he was reported to have taken up a post at Dr Jeff Bradstreet’s treatment centre in Florida (he has since moved on to another private clinic in Texas). According to Dr Wakefield, he donated the income he received from the litigation to support the foundation of a research unit dedicated to bowel problems in autistic children, first (unsuccessfully) at the Royal Free and later in the USA. According to Deer, the accounts of these organisations reveal that he was a recipient of funds from them rather than a donor.

The biggest single earner from the litigation was Professor John O’Leary who set up the firm Unigenetics to process requests from parents to test bowel and other specimens for traces of measles virus that Dr Wakefield believed would confirm his MMR-autism hypothesis. Indeed, the publication in 2002 of two papers by O’Leary’s team purporting to demonstrate measles fragments in autistic children appeared to many parents – though not to sceptical experts – to provide powerful evidence for the Wakefield theory. Two recent papers have conclusively refuted O’Leary’s findings (1,2). The recognition by the LSC that it could not rely on the results from O’Leary’s laboratory was one of the key factors in its decision to abandon the litigation. These tests ultimately failed to confirm a link between MMR and autism in a single child and left more than a thousand families with dashed hopes. Professor O’Leary and his colleagues received more than £700,000. No further publications in this field have emerged from his department.

Though the detailed figures have not previously been available, it has long been known that Dr Wakefield and Professor O’Leary had derived a substantial income from the litigation. Perhaps the most valuable revelation in the LSC’s recent document concerns payments to a number of individuals who have provided Dr Wakefield with vital public backing at key moments in the unfolding controversies surrounding MMR over the past decade. Many of these Wakefield supporters had not declared that they were beneficiaries of the litigation, though this might be considered a significant factor.

Dr Kenneth Aitken (£230,000) was formerly a clinical psychologist at Edinburgh children’s hospital but now works in private practice. He is closely associated with the burgeoning world of autism quackery in Scotland (9). He supported the Wakefield position at one of the Medical Research Council investigations and at the Scottish Executive inquiry in 2001. Dr Carol Stott (£100,000) was engaged on postgraduate research in autism in Cambridge before her suspension for sending abusive emails to Brian Deer. She has collaborated with Dr Wakefield on a number of articles published in anti-vaccine journals and runs a pro-Wakefield website. She has recently been appointed ‘associate professor’ at Dr Wakefield’s new clinic in Texas.

Dr Peter Fletcher (£40,000) was head of the committee on safety of medicines in the 1970s and emerged from retirement to endorse Dr Wakefield’s critique of MMR safety in 2001. He is regularly quoted by anti-MMR journalists, but refuses to speak to anybody critical of the Wakefield campaign. Dr Peter Harvey (£10,000) was an adult neurologist at the Royal Free who examined the children in Dr Wakefield’s Lancet study. He subsequently took early retirement and now has a practice in Harley Street providing expert testimony in relation to litigation claims. He has provided occasional endorsement for Dr Wakefield’s claims in the press and on television.

Mr Paul Shattock (£8,000) is the parent of an autistic son and a retired lecturer in pharmacy who provides urine tests of no known scientific value purporting to provide a guide to dietary treatments for autism from his HQ in the University of Sunderland. He is a long-standing public promoter of the Wakefield campaign. Dr Richard Halvorsen is a private GP in central London who runs a business selling measles, mumps and rubella as separate vaccines to parents rendered fearful of the triple jab by the anti-MMR campaign (of which he is a vocal supporter). He received only £6,000 from the litigation. However, a clinic just north of London providing a similar service was at one time reported to have a turnover of £17,500 a week (though it is now defunct since its proprietor, Dr David Pugh, was imprisoned for fraud in 2005 and struck off the medical register last year).

What emerges from these documents is that there does not appear to be a single professional supporter of the Wakefield campaign who was not also a beneficiary of the anti-MMR litigation. If Dr Wakefield’s British supporters appear a rather undistinguished bunch, they are paragons of professional virtue and integrity by comparison with Dr Wakefield’s US backers, such as Drs Bradstreet (£22,000), Krigsman (£17,000) and Geier (£7,000) (10).

It is not surprising that Brian Deer has attracted hostility from Dr Wakefield and his supporters. It is sad that he has also been denounced by a few parent campaigners who continue to regard Dr Wakefield as a hero. In truth Deer has emerged as a forceful champion of families affected by autism by exposing the truth about a campaign that has caused enormous distress to parents of children with autism as well as provoking unwarranted anxieties about MMR. While leading autism specialists and organisations have been largely ineffectual and much of the media (from Private Eye to the Daily Mail, from the Telegraph to BBC Radio 4’s Today programme) has been duped by Wakefield at one time or another, Deer has provided an invaluable service by revealing how much cash and cynicism has surrounded the campaign against MMR.

Much relevant documentation can be found on Brian Deer’s website and further background on the anti-MMR litigation and the personalities involved is provided in my book, MMR and Autism: What Parents Need To Know, published by Routledge, 2004.


Britain to abolish head-teachers?

The days of the "hero head", who manages everything in a school from hiring staff to ordering books, could be numbered, according to a report which suggests that business leaders with no classroom experience could run schools. Leaders with a classroom background would still be required for teaching and learning, but there was no reason why they should not report to a principal or chief executive, responsible for overall strategy and non-academic operations.

The report, prepared for the Government by the consultants PricewaterhouseCoopers, follows fears of an impending shortage of head teachers and concerns that workloads, bureaucracy and over-regulation were deterring deputies from applying for headships. Although ministers deny there is a recruitment problem, they acknowledge that the job of leading a school is now so complicated that a new, "modern" approach is needed.One of the biggest barriers to reform identified by the report is the "hero head" perception, among teachers, parents and heads themselves, which presupposes that for big decisions, "only the head will do". Distributing leading responsibilities among a team was often more effective, it concluded.

The report recommends that schools consider new types of leadership: a federated model brings groups of schools under one "super-head"; a multi- agency model has schools run by a team that includes teachers and staff from other agencies, such as health and social care. Schools could also be clustered into groups, with heads rotated from school to school.

The structure of governing bodies should also be changed, the report says, suggesting the creation of "meta-governors" working across a number of schools in a locality. It also recommended greater flexibility in the rewards offered to heads. As well as increasing the pay differential between heads and other staff, it suggests allowing heads to take time off during term time.

Teaching unions were divided over the findings. John Dunford, the general secretary of the Association of School and College Leaders, said he was not opposed to non-teachers being brought into certain school leadership roles: "The possibility should be opened up that the best of school leaders who are not qualified teachers - the bursars and business managers - should be able to come through to the top job, provided that the person in charge of teaching and learning is a qualified teacher."

But Steve Sinnott, the general secretary of the National Union of Teachers, said: "The primary purpose of schools is to educate pupils, not to be commercial organisations. Head teachers have told the Government they do not believe that those without teaching experience can run our schools."

Jim Knight, the Schools Minister, said that the report's recommendations would be discussed with the teaching and support staff unions before any action was taken. The National College of School Leadership would be given 10 million pounds to support its strategy to help to identify future head teachers and cut the time that it takes to qualify, he said.


Another boffin jumps off the warming ship

Add another world-renowned scientist to the list of man-made global warming skeptics. Nigel Weiss, professor emeritus at the University of Cambridge's department of applied mathematics and theoretical physics, and past president of the Royal Astronomical Society, is a sunspot guy. He argues that the world will be soon facing a cooling period.

In an interview with Lawrence Solomon of Canada's Energy Probe Research Foundation, a widely-respected Toronto-based environmental and consumer group, Weiss argues that while manmade greenhouse gases have some role, the scale of which is yet unknown, in global climate, the sun if far more important. "Variable behavior of the sun is an obvious explanation" of climate change, he said, adding that "there is increasing evidence that Earth's climate responds to changing patterns of solar magnetic activity."

The interview was published in the National Post, Canada's conservative-oriented national newspaper founded in 1998 by media mogul Conrad Black.

Weiss, 70, a native of South Africa, says sunspots are the markers of changes in solar activity. Typically, sunspots follow a cycle of about 11 years. But that hasn't been the case for the last 50 or so years, he notes. "If you look back into the sun's past," he says in the interview, "you find that we live in a period of abnormally high solar activity."

But these years of hyperactivity don't last, says Weiss. "Perhaps 50-100 years, then you get a crash. It's a boom-bust system, and I would expect a crash soon." According to Weiss, the sun's polar field is now at its weakest since the 1950s. When there is a crash every 200 years or so, sunspots vanish, solar activity declines, and the globe cools dramatically. These phenomena are known as "grand minima," and they have occurred with rough regularity over at least the past 10,000 years.

Notes Weiss, in the 17th century, sunspots almost completely vanished for around 70 years. That coincided with the Little Ice Age, when Viking colonies fled Iceland, Finland lost 50% of its population, and New Yorkers could walk on the ice from Manhattan to Staten Island.

By contrast, says Weiss, long periods of solar activity, such as we have experienced in the last 50 years, can produce dramatic warming. The example was the Medieval Warm Period, which drew the Vikings to Iceland and created a thriving wine industry in England - the source today of much dirty dancing among policymakers looking at the so-called `hockey-stick' climate record of Michael Mann et. al.

I found this very interest article on how Energy Probe worked with the Harris government in Ontario to try to privatize the whole electricity system.
