ACOEM Publishes Chronic Pain Guidelines

ACOEM Publishes Chronic Pain Guidelines

The American College of Occupational and Environmental Medicine has published new medical treatment guidelines for providing care to workers with chronic pain. The guidelines are available online now; in September a print version will be available.

More than 200 recommendations for chronic pain are outlined in the new evidence-based guidelines, which ACOEM says were developed by a multi-disciplinary panel of national experts and reviewed by representatives of leading medical and health organizations. The recommendations focus on diagnostic and other testing and treatments for several chronic pain conditions, including complex regional pain syndrome (CRPS), neuropathic pain, trigger points/myofascial pain, chronic persistent pain, fibromyalgia, and chronic low back pain. An extensive volume of literature was used to develop the recommendations, which feature more than 1,500 references, including 546 randomized controlled trials.

“These guidelines were developed using ACOEM’s published methodology, which incorporates the highest scientific standards for reviewing evidence-based literature, ensuring the most rigorous, reproducible, and transparent occupational health guidelines available,” said Editor-in-Chief Kurt T. Hegmann, M.D., MPH. “Literally thousands of hours of review of the available scientific literature went into this process, yielding what we consider state-of-the-art medical guidelines.”

Other highlights of the guidelines include:

  • An in-depth review of over 20 medications (prescription, over-the-counter, complementary and alternative) used to treat patients with chronic pain, including an extensive appendix on guidance for the use of opioids.
  • Detailed recommendations regarding the use of appliances (e.g., magnets), skilled allied-health provided medical therapies (e.g., acupuncture, manipulation/mobilization, myofascial release), electrical therapies (e.g., PENS, TENS).
  • Uses and limitations of injection therapies (e.g., diagnostic and therapeutic facet joint injections, trigger/tender point injections, botulinum injections, intrathecal drugs).
  • A discussion of spinal cord stimulation for CRPS and other painful conditions.
  • A detailed review of psychological services (e.g., evaluation and behavior therapy) and rehabilitation for delayed recovery, including biofeedback, work conditioning/work hardening/early intervention programs, and interdisciplinary pain rehabilitation programs.
  • A focus on functional restoration, including an active exercise program and behavioral program.

In addition to being available electronically, the guidelines also will be available in a new print edition of the Occupational Medicine Practice Guidelines 2nd Edition, 2008 Revision, which is currently in production. Orders are being accepted now for delivery in September of this volume, which includes guidelines on a variety of musculoskeletal conditions. Individual chapters from the print publication are also available at ACOEM’s Web site.

ACOEM’s online treatment guidelines are exclusively distributed by Reed Group. For more information, or to order UMK Professional or the ACOEM Guidelines Electronic version, visit www.reedgroup.com or call (866) 889-4449.

Abstract

To assess the effects of intravenous administration of the free radical scavenger mannitol 10% on complaints associated with complex regional pain syndrome Type I (CRPS I), a randomized, placebo-controlled, double-blinded trial was performed. Forty-one CRPS I patients according to the Bruehl et al diagnostic criteria, were included in 2 outpatient pain clinics of 2 university medical centers and randomly assigned to receive either 10% mannitol iv in 1 L 0.9% NaCL in 4 hours for 5 consecutive days or equal volumes of 0.9% NaCL (placebo). Patients in both groups received physical therapy according to protocol and rescue pain medication if required. Complaints on impairment and disability level and quality of life were assessed up to 9 weeks after baseline, with primary measurement points at 2, 6, and 9 weeks. Monitoring of pain using the visual analogue scale took place continuously during the course of the trial. Except for a significant improvement on a subscale of the Jebsen-Taylor hand function test, no significant differences were found between mannitol and placebo treatment. Changes in both groups in the course of the trial were small and clinically irrelevant on all measurement indices. We conclude that intravenous administration of 10% mannitol is not more effective than placebo in reducing complaints for CRPS I patients and provides no addition to already-established interventions for CRPS I. Whether 10% mannitol can provide beneficial effects for subgroups of CRPS I patients with a pathophysiological profile more closely fitting the presumed mode of action for this intervention remains to be established.

Perspective

This article addresses the efficacy of the intravenous administration of the free radical scavenger mannitol for treatment of CRPS type 1. This intervention is not more effective than placebo in reducing complaints for CRPS I patients and provides no addition to already-established interventions for CRPS I.

ABSTRACT

Objective. Advanced complex regional pain syndrome (CRPS) remains very difficult to treat. While subanesthetic low-dose ketamine has shown promise in early localized CRPS, its use in advanced CRPS has not been as effective. Since ketamine’s analgesic potency and duration of effect in neuropathic pain are directly dose-dependant, we investigated the efficacy of ketamine in anesthetic dosage in refractory CRPS patients that had failed available standard therapies.

Methods. Twenty ASA I-III patients suffering from refractory CRPS received ketamine in anesthetic dosage over 5 days. Outcome criteria were pain relief, effect on the movement disorder, quality of life, and ability to work at baseline and up to 6 months following treatment.

Results. Significant pain relief was observed at 1, 3, and 6 months following treatment (93.5 ± 11.1%, 89.4 ± 17.0%, 79.3 ± 25.3%; P P P

Conclusions. This open-label trial suggests benefit in pain reduction, associated CRPS symptoms, improved quality of life and ability to work following anesthetic ketamine in previously refractory CRPS patients. However, a randomized controlled trial will be necessary to prove its efficacy.

Humans are more important than animals


Tuesday 26 August 2008

Stuart Derbyshire


Humans are more important than animals


When it comes to using animals in research, the only moral judgement should be: does it benefit humankind?

Last week, the scientific journal NeuroImage published an article arguing that ‘by and large animal models offer very limited insights into the complex clinical picture of pain’ (1). The authors claimed that new procedures with humans, especially functional neuroimaging, should be more broadly adopted instead of animal-based studies into the nature and causes of pain.

BBC News, and several anti-vivisectionists who were invited to comment on the report on various radio stations, interpreted this as a call to end animal pain-research (2). The publication of the article came in a week (17 to 22 August) when the World Congress on Pain was taking place in Glasgow (3). I was there, along with several of the authors of the NeuroImage paper and hundreds of students, clinicians and academics who treat patients with pain or who research the causes and effects of pain.

‘Animal models’ try to recreate disease in an animal in order to study the progress and treatment of the disease in a highly controlled fashion. There are, without doubt, many problems with this approach to disease (4). Even the best animal models cannot hope to mimic all the facets of human disease. How, for example, can we model frustration at no longer being able to play football by using rats in a laboratory? We can’t, and the same is true for almost all psychological reactions to disease.

This is a particularly acute problem for pain researchers because some of the most troublesome chronic pain disorders – such as fibromyalgia, non-specific low back pain, irritable bowel syndrome and so on – do not have an obvious physical cause and psychological factors loom large. And animal models tell us little about these factors.

These problems are not, however, insurmountable. Anyone who has missed a night or two of sleep will likely be familiar with fatigue and feeling somewhat bruised with aches and pains in their joints and muscles. This feeling is not unlike what fibromyalgia patients report, and sleep-deprived rats can provide a model to explore the causes of at least some of the symptoms of fibromyalgia. There were 37 presentations at the World Congress on Pain that describe animal pain models, including models of complex regional pain syndrome, bone fracture pain, osteoarthritis, neuropathic pain and visceral pain. Almost 200 presentations included ‘animal’ in their title and almost all of the talks on neurobiology included a reference to animal research to establish the basic knowledge.

So why, then, has NeuroImage thrown in the towel and run an article calling on these researchers to consider doing something else? In part, this has come about because of several new pain drugs that have failed the transition from animal to human. A class of drugs known as the NK antagonists, for example, works well in animals but has been largely ineffective in human trials. This is disappointing, but perhaps not that surprising. The most successful drugs for pain are opioids (poppy juice) and aspirin (willow bark), which were both discovered hundreds of years ago. Treating pain is difficult and there is a long history of failure. It seems unlikely that any one approach – animal models, brain imaging, microdosing or whatever – will suddenly yield success.

At the Congress I was able to meet with some of the authors and ask them about their article in NeuroImage (5). Those I spoke to agreed that animal research has played an important role in developing our understanding of the basic physiology of pain and that the BBC News headline overstated the case against animal pain-research. There was general agreement that animal research will continue to play an important part in advancing our understanding of pain biology. Opinions differed about the future role of animal research in drug discovery.

I think this is a necessary and sensible argument for pain researchers to have, and there is a strong case to be made for de-emphasising the role of animal models in developing pain therapy. Personally I am not convinced that any technique is likely to take us closer to curing the most troublesome pain disorders and so I believe we should continue with a broad approach and see what we get. But I understand that others see a way to success by redirecting resources from animal models towards neuroimaging, clinical trials, human tissue banks and other techniques of human study. I welcome the debate and the effort to put our money where our collective mouth is.

However, a major problem with the NeuroImage article is that the debate was posed not just as a scientific issue but also as an ethical one. The article followed a meeting organised by Focus on Alternatives, a group which brings together representatives from British non-profit organisations that advocate methods to replace the use of laboratory animals in research, education and testing (6). Members of Focus on Alternatives include the Hadwen Trust, which funds exclusively non-animal techniques in an effort to eradicate animal research (7). The Hadwen Trust does not believe that animal experiments are ethically supportable.

Gill Langley works for the science department of the Hadwen Trust – and she and her husband Chris Langley were both authors on the NeuroImage paper. Chris Langley was the lead author and is probably responsible for the tone of the paper being negative about the prospects for animal research. There is a very big problem when ethical concerns latch on to scientific discussion in this manner.

The ethical case for moving away from animal models of disease is based on a principled objection to animal research. That objection is based on the belief that using animals instrumentally to benefit humans is morally wrong and so animal research, and all instrumental use of animals, should stop. I have documented my many objections to this stance elsewhere (8). If we were to accept that using animals for research is morally wrong, then such research should logically come to an end, with no ifs or buts. That would be a potential disaster for medical research and experimentation.

Realising that this is likely to be a tough sell, moderate anti-vivisectionist groups, like Focus on Alternatives and the Hadwen Trust, have tried to sneak an ethical argument into scientific discussion by suggesting that animal procedures are not desirable and in an ideal world we would do something else. These arguments are spurious and should fail. Without a thoroughgoing principled objection to animal research, the only grounds for proceeding, or doing something else, are the needs of human beings. If we consider chronic pain an important issue for human beings, and animal models provide a way towards a cure, then we should do more – lots more – animal research. Under these circumstances, the more animal research we do, the more moral we are being.

We can argue that we should not waste our time and resources on rubbish animal models, which is what at least some of the authors of the NeuroImage article were hoping to get at, but not that animal models are immoral, which is what the Langleys believe.

Focus on Alternatives has successfully played a trick. It called a meeting of some excellent scientists for a creative discussion on how to advance human models of pain and better address the problem of pain. Its members then wrote an article ostensibly addressing the scientific problem of using animals but with an ethical objection to animal research layered on top.

This is a trick that campaigners have pulled off successfully before with a workshop on sepsis to address the limited value of animal sepsis models (9). Previously, however, this trick has not led to publication in a major specialist science journal such as NeuroImage. The publication in NeuroImage represents a propaganda coup for those who oppose animal research in principle and is to be very much regretted.

Stuart Derbyshire suggested we need to have the hard arguments in favour of animal research. Helene Guldberg made the ethical case for vivisection and was told by Professor John Martin why animal research is justified.

I also spoke with several other colleagues and friends at the congress who work with animal models of pain. The general consensus was that we are suffering from some overblown expectations of what animal models can deliver, but that animal models remain an important component of research into pain. The opinions and comments expressed in this article reflect that consensus but the reflection is being done by the author and the opinions should be attributed to the author alone. I make no claim to be speaking on behalf of the World Congress on Pain or anyone else except myself.

More kids need help in coping with pain

More kids need help in coping with pain

Posted by Brie Zeltner August 25, 2008 16:27PM

Despite big advances in the understanding and treatment of pain in children, chronic pain in kids remains an undertreated problem.

The myth that children don’t feel the same amount of pain adults do persists, despite diagnoses of “adult” conditions such as fibromyalgia, chronic fatigue syndrome, irritable bowel syndrome and intractable headaches.

At the Pain Center at Akron Children’s Hospital, a team of pediatric pain specialists, massage therapist, acupuncturist, nurses, physical therapists and other experts come together to care for kids much like in an adult pain center. The main difference is that treatment of pediatric pain patients always is more conservative, said director Dr. Ibrahim Farid.

“Anytime I give a kid a medicine, I still think of it as a conservative treatment, but I try to save that as a last resort,” he said.

His plan for most kids relies heavily on physical therapy, coping techniques, massage therapy and acupuncture, which all are available in the same office.

“I do believe in the biology and the physiology of the patients [to heal] themselves,” he said.

After three years of pain, frustration and bouncing from doctor to doctor, 17-year-old Jacqui Reese was tired of trying to convince everyone that the pain in her legs wasn’t from shin splints. Her toes were so stiff they wouldn’t bend, her legs would swell up and turn blotchy, and her shins felt like they were being repeatedly stuck with knives.

Reese, of Doylestown, finally found relief at the Akron pain center after Cleveland Clinic doctors diagnosed her with fibromyalgia and complex regional pain syndrome, a little-understood disorder that can strike after an injury has healed and causes continued pain and swelling.

She has been pain- and medication-free since completing six months of therapy in February.

“In the first month, it was really amazing how much of a difference there was,” Reese said. A dedicated soccer player, she recovered even faster when she stopped occasionally jumping in at practices and decided to just work on getting better.

“I want to play in college, so I want to focus on that and not risk going through what I did before.”

Never too late to learn

Never too late to learn

9:40am Friday 22nd August 2008

A 37-YEAR-OLD Netherton man is proving it is never too late to learn after scooping a top grade in an AS Level exam.

Father-of-three Jason Collins, of Spring Road, Netherton is a mature student at Dudley College and scored an A grade in English Literature.

He already has four A grade A-Levels under his belt in history, psychology, sociology and law and was even placed in the top five highest achieving law students in the country last year.

The impressive succession of results is a far cry from his school days, which Jason admits he “wasn’t bothered” about.

Jason has also managed to defy illness after being struck down with Complex Regional Pain Syndrome, which left him confined to a wheelchair six years ago.

But undeterred by his illness, Jason decided he wanted to get back into work and is aiming towards a career in law, possibly in the probation service.

He added: “I find law fascinating, you could say it floats my boat and I am going to Walsall to do a one year law course from September.

“It used to do my head in being stuck at home, unable to work, I needed to be doing something, so I decided to get my grades.

“I would encourage everyone to just go and do it, the benefits are enormous.”

Jason was joined at the nerve wracking result opening moment by two of his daughters, who went to support their clever dad.

He said: “I want to make sure they all do well at school, I now realise how important education is. I will always encourage them to get good grades. I just wish I had done it years ago.”
