Insulin Resistance and Equine Laminitis Research: Australia's Melody De Laat's Academic Elevator Video

Imagine the challenge laid down by the University of Queensland to its graduate researchers: give a three-minute presentation encapsulating your doctoral work. Tell an audience of everyday people from all walks of life why it matters, what it's all about. But keep it short. Can an Australian laminitis researcher describe equine metabolic syndrome in that short amount of time--using only one slide? 3-2-1...talk!

What's your elevator speech?

You have to have one.

If you're an entrepreneur, a job seeker, self-employed or just someone who doesn't want to be left in the dust of this ever-changing world, you have to have to an elevator speech. Once all you needed was a firm handshake, and a spare business card in your wallet for when you met someone. Now you need to be able to tell him or her what you do with your life and why you do it in just a few words.

You need to be able to get the message across that you're special and you're interesting and you're worth knowing/hiring/considering, and you need to say exactly why--all in the time it would take to ride a couple of floors on the elevator of a hotel or office building.

When that elevator door opens, your speech is over.

Yes, you're saying...But then there are academics. And forget engineers. Have you ever asked a researcher or engineer what he or she actually does? I know what you're thinking: Maybe there are some elevators in some coal mines in some Third World countries that would take long enough for a researcher's speech to get to the point--if there is one, that is.

But things are changing. We live in an age of pecha-kucha, the PowerPoint challenge to present your idea in 20 slides that change every 20 seconds, whether you're ready or not. It's the age of the "unconference". And the two-minute video rules, thanks to the way that YouTube has reset our attention spans.

So imagine the challenge laid down by the University of Queensland to its graduate research community: give a three-minute presentation encapsulating your doctoral work. Tell an audience of everyday people from all walks of life why it matters, what it's all about. But keep it short.

And if you get your message across? You could be the winner.

Last year, Melody De Laat answered the UQ Three Minute Thesis competition challenge with a topic related to her thesis: The Investigation of Insulin-Induced Laminitis in Horses. Her research at the Australian Equine Laminitis Research Unit (AELRU) focused on how elevated insulin levels, which occur as a result of insulin resistance, damage the sensitive lamellar (laminar) structures of the horse's foot.

And she had to do it on a huge stage, in an even bigger theater, in front of people who knew nothing about horses' feet, let alone about laminitis or insulin resistance.

“Insulin resistance is an increasingly common problem in horses. The lamellar failure, which is known as laminitis, that results as a consequence of the elevated insulin levels in the body is a painful and debilitating condition,” Melody said confidently.

“By uncovering the mechanisms involved in insulin-induced laminitis it is hoped that we will be able to reduce the morbidity and mortality rates associated with this disease.”
 
The Queensland competition was so well-received that it has been extended to other national and international universities in Australia and beyond. Master of Ceremonies for the event is the award-winning science writer and broadcaster with ABC Science Online, and regular judge on Australian ABC TV's The New Inventors, Bernie Hobbs.

I hope you enjoyed Melody's equivalent of her elevator speech. She advanced to the finals, and there are a lot more people in Australia who know a little bit about laminitis thanks to this competition and Melody's PhD.

And--Oh! Is this your floor?

One of Melody De Laat's research breakthroughs on metabolic laminitis was featured on The Hoof Blog on July 1, 2011. If you'd like to learn more, Melody De Laat will be one of four doctoral and post-doctoral researchers from the Australian Equine Laminitis Research Unit (Simon Collins, Melody De Laat, Brian Hampson and Andrew Van Eps are the team) who will accompany AELRU director Chris Pollitt to speak at the 6th International Equine Conference on Laminitis and Diseases of the Foot in West Palm Beach, Florida October 29-31.

Laminitis Research: Australian Breakthrough on Insulin Function in Equine Foot

(Text published as provided)

Researchers funded by the US-based Animal Health Foundation announced June 15, 2011, that they have made a major breakthrough in understanding how the insulin form of laminitis occurs.

Drs. Melody de Laat and Chris Pollitt of the Australian Equine Laminitis Research Unit at the University of Queensland have discovered that receptors designed to receive insulin-like growth factor 1 (IGF-1) may be binding to insulin instead if horses have high levels of insulin.

This groundbreaking discovery may enable scientists to develop strategies to try to block IGF-1 receptors from receiving insulin and prevent the disease from occurring.

The receptor also has been shown to be responsible for the metastatis of malignant tumors in humans, and drugs currently are being developed to block the receptor. These drugs may be of use in trying to treat horses that are prone to laminitis from developing high levels of insulin.

Insulin is important in regulating the blood glucose within animals, but horses that have Equine Metabolic Syndrome and Cushing’s disease often have very high levels of insulin.

Pollitt and his team, funded by AHF since 1995, previously showed that high insulin is one of the major pathways that causes laminitis, but, to this point, they had not understood how.

The equine foot is very dependent on glucose for metabolism, but it is not dependent on insulin to deliver that glucose. Horses have a large number of IGF-1 receptors in their feet, but no insulin receptors. Pollitt’s team now theorizes that these IGF-1 receptors are being stimulated by insulin that mimics insulin-like growth factor 1 and is binding to these receptors.

When this happens, the laminar epitheleal cells start to proliferate. Normally these cells in the middle of the foot don’t multiply. The cells are made at the coronary band and migrate all the way down to the sole without multiplying.

This type of proliferation causes the laminae to stretch and lengthen and the weight of the horse to ruin the bond between the external hoof wall and the bone. The bone changes position, and laminitis occurs.

“We’re starting to understand the pathway of how insulin really causes laminitis,” said Dr. Don Walsh, president of the Animal Health Foundation.

Grayson Laminitis Research Funding Breaks New Ground: Richardson, Pollitt and Van Eps Join Forces for International Support-Limb Laminitis Prevention Study

Today the Grayson Jockey Club Research Foundation announced its selection for the 2011 round of equine research projects that will be funded.

Laminitis research figured prominently in the mix of subjects to be studied. In particular, two studies will receive support from the Lexington, Kentucky-based charitable organization.

The first covers the dreadful form of laminitis that led to the death of 2006 Kentucky Derby winner Barbaro. This will be a multiple-year study; "first year" refers to the funding applied for 2011. Andrew van Eps received his PhD at the University of Queensland in Australia by studying laminitis; his previous contributions have included the first studies of the use of cryotherapy to prevent laminitis.

Here are the Grayson descriptions of the new studies:

Laminar Energy Failure in Supporting-Limb Laminitis

Dr. Andrew Van Eps, University of Queensland--First Year

Andrew Van Eps BVSc, PhD, MACVSc, DACVIM A frequent and disheartening result of injury repair is that the leg opposite the one injured develops laminitis. This is known as supporting-limb laminitis and is what eventually caused Barbaro to be euthanized. Although it is a common occurrence, the mechanisms of the malady have not been established. This project is headed by a young researcher, but the co-investigators are world renowned Drs. Dean Richardson and Chris Pollitt. Professor Chris Pollitt BVSc, PhD The project involves testing the hypothesis that supporting-limb laminitis is a result of reduced blood supply to the connection between hoof and bone (lamellar tissue). Further, that the blood supply in normal circumstances is encouraged by a regular loading and unloading of the legs and hooves (alternating which one is bearing the most weight). Injury to one leg interrupts that alternating pattern. The researchers will test the hypothesis with a state of the art, minimally invasive technique known as tissue mycrodialysis in conjunction with three dimensional computed tomography to develop effective methods of preventing or minimizing lamellar tissue energy failure. Comments in the Research Advisory Committee evaluations included “may well provide immediately applicable strategies to prevent supporting-limb laminitis” and “really nice grant, new idea about a devastating problem.” Dr. Richardson received second-year funding for his ongoing study of laminitis: Dr. Dean Richardson, University of Pennsylvania--Second Year In Vivo Gene Transfer for the Treatment of Laminitis Dean Richardson DVM, DACVS This project seeks to develop a gene therapy approach to prevent laminitis in the contralateral hoof when a horse is being treated for a musculoskeletal injury. This, of course, was what eventually ended the efforts to save Barbaro and is a frequent threat to horses with hoof and leg injuries. The well known research team already has compelling preliminary data which encourages the hypothesis that use of recombinant adeno-associated viruses can be used as vectors to deliver a therapeutic gene (TMP-3) to the lamellar tissues. This is meant to inhibit the damage to the epidermal laminae without disrupting the normal hoof structure. Another completely new study will begin at The Ohio State University, where the mechanism of cryotherapy in averting laminitis will be studied and, hopefully, recreated via pharmacology. Digital Hypothermia in Laminitis: Timing and Signaling Dr. James Belknap, The Ohio State University--First Year The most recent figures from a study involving the USDA and State Veterinary Medical Officers project that at any given time laminitis affects 8 of every 1,000 horses in the United States. Based on the American Horse Council survey that there are 9.5 million horses in the nation, that would indicate 76,000 horses being affected at any given time. Of those affected, the USDA survey found that 4.7% died or were euthanized, or about 3,572 deaths from laminitis annually. The authors of this project report that “an integrated research effort over the last decade has enhanced the current understanding of the pathophysiology of equine sepsis-related laminitis (one of numerous causes of the disease). This has mirrored progression of sepsis research in human medicine by moving from (an earlier) concept . . .to determining that a marked inflammatory injury takes place and is likely to play a prominent role in tissue injury and subsequent failure.” However, there have been persistent failure of systemic therapies for organ/laminar injury in both human and equine medicine. One advantage laminitis presents is that it effects the hoof rather than visceral organs, lending itself to artificial cooling more readily. In a present project funded by the Foundation, digital hypothermia (cooling of the hoof) prior to onset of carbohydrate overload-induced equine sepsis resulted in dramatic decrease in laminar inflammatory signaling. The next goal is to find pharmaceutical therapies which can accomplish the same without the cumbersome aspects of maintaining constant hypothermia to the equine hoof (hooves).

Education Connection: Speakers at Equitana Australia November 18-21, 2010

Jockey-turned-farrier Laurie Paltridge is one of the few people in the world who can say he has both ridden and shod the winner of his nation's top jumping race. You can hear Laurie speak and watch his shoeing demonstration if you happen to be lucky enough to be in Melbourne, Australia next week, where the Downunder edition of Equitana will be underway. Laurie is one of many speakers addressing hoof and lameness problems in sport and recreational horses at the event. Photo mirrored from the Melbourne Standard.

Melbourne, Australia may be half a world away for our USA readers, but if you read the statistics of who reads this blog, you will know that a good number will be attending Equitana Downunder this week. The organizers have put together an interesting program in equine lameness with something for everyone--no matter what your bent, from the alternative to the mainstream, from the traditional to the high tech, a speaker will be presenting on your wave length.

This is quite a switch from most horse expos, which seem to choose speakers based on exhibitor and sponsor provided experts, or the current popular circuit speakers. While popular speakers bring in crowds, they don't always provide a balanced view of what's going on in the field. It takes a roster of speakers to achieve that goal, and rosters cost money.

The biographies you'll read in this post are presented as supplied by Equitana, and they were surely only slightly edited from what the speakers provided, so please keep that in mind as you read.

Lots of information about Equitana Melbourne can be found online; most of the speakers have their own web sites as well. The original Equitana, in Essen, Germany, will be held in March 2011, and is one of the most outstanding equine/equestrian educational/commercial events in the world. The German show includes the famous Hufdorf, or Hoof Village, as well as a new Center for Excellence for Equine Welfare.

Spinal pain and/or dysfunction, and related stiffness, behavioral and performance problems, are the main focus of Dr. Ian Bidstrup's veterinary practice. He is one of a handful of Australian veterinarians using the combination of acupuncture, prolotherapy and veterinary chiropractic to treat these problems.
In addition to a veterinary degree, Ian has a masters degree in chiropractic science and international qualifications in acupuncture. He lectured part-time in animal chiropractic at RMIT Univeristy from 2002 to 2009 and in saddle fitting for the ASFA level 1 and 2 courses from 2000 to 2009. His presentation this EQUITANA Melbourne is on sacro-iliac joint complex troubles.

Andrew Bowe began working as a farrier in 1990 after graduating from Dookie College (B.App.Sc). He is a Trade Accredited Master Farrier with a difference. His business combines a lifetime's experience of traditional farriery with modern barehoofcare ideas (training horses' feet to be healthy and strong enough to be ridden without horseshoes).

He specialises in returning chronically lame horses back to soundness with barefoot rehabilitation: restoring correct form, movement and function to horses' feet, using modern hoof boots when necessary.

Known as 'The Barefoot Blacksmith' he travels Australia-wide, teaching horse owners how they can help their horses grow and maintain healthy feet, the foundations to a healthy horse.

Jeremy Ford, a farrier of 16 years is now a professional natural hoof care specialist.  He runs his practice Wild About Hooves in Tasmania with his partner and barefoot endurance rider, Jen Clingly.


After being introduced to barefoot trimming he has hung up his hammer and stored the anvil to promote healthy, sound, metal-free horses.

Jeremy has been involved with horses all his life in all disciplines including hunting, endurance and stock-work.  His encounters with wild Australian Brumbies in the outback were the major inspiration for the switch to barefoot.  These horses have hooves, hard and strong, and able to cope with the hardest terrain.  This natural world led him to study with the AANHCP (American Association of Natural Hoof Care Practitioners).

Jeremy's life revolves around horses' hooves.  He runs educational workshops on hoof care Australia wide and is principle lecturer in the trade certificate Equine Hoof Care course run by the government education institute, TAFE.  Wild About Hooves runs annual tours to the outback to observe brumbies in their natural desert environment.  Coupled with this, they have produced educational documentaries and hoof trimming tools.

The aim of Wild About Hooves is to highlight the bare facts of keeping horses without shoes, about changing horse keeping practices to complement evolutionary needs and ways to adapt our domestic home environments and to keep some of the "wild" elements for the health and happiness of our horses.

Dianne Jenkins is a passionate and highly successful equine specialist.  During 25 years of practice, she discovered that many horses suffer from previously unidentified patterns of common low-grade injuries that cause postural, training and behavioural issues and lead to lameness.

Her research indicates that she has solved the mystery of equine chronic lumbar pain that cannot be diagnosed by radiograph or ultrasound.  She can explain the primary cause and gradual patterns of compensatory issues that lead to early wear and tear and ultimately joint dysfunction.  These experiences and abilities led her to develop the Jenkins method of Equine Neurophysiological Therapy (JENT); a system that integrates comprehensive scientific knowledge with therapy.

Dianne presently resides in Ireland and travels abroad to work on horses by appointment. Learn more about her work at www.diannejenkins.com.au

Kevin Keeler has been a farrier for over 30 years and has experienced first hand the physical demands of working on horses feet.


Inspired by an injury early in his career, and then later after having survived a plane crash in the Idaho backcountry while being flown to work on ranch horses, the concept of a lightweight and safe hoof support system was borne.  Wanting to get the weight off his body while working under the horse, Kevin developed the Hoofjack®.  The Hoofjack® was designed to fully support both the front and hind feet of a horse and can be used by anyone providing hoof care such as the farrier, barefoot trimmer, veterinarian, or horse owner.

Kevin travels internationally sharing with the equine community the benifits of using the Hoofjack® for both the horse and the hoof care provider.  Kevin is the owner and CEO of Equine Innovations Inc., which in addition to manufacturing the Hoofjack® also manufactures the Tooljack® a unique tool cart designed to hold farrier tools and equipment.  Although "officially" retired as a farrier, Kevin still maintains a clientele of approximately 60 horses and lives in Star, Idaho, USA, with his wife Dawn, 2 dogs, cat, goat and 2 horses.

Helen Klowss is a qualified Horse Masseur and has been a leader in this field for over 16 years.  She has worked with horses in many aspects of the equine industry in Australia and overseas.

In 1968 Helen was employed by the legendary racehorse trainer Bart Cummings as a strapper and spent many years acquiring knowledge and experience with the master trainer.  Specialising in nursing and rehabilitating racehorses with training injuries, Helen soon discovered that she had the ability to see unsoundness in horses which seemed obscure to others. Knowing that there was more than the conventional treatment involved in the healing, recovery and ultimate return to racing, Helen set out to develop a form of treatment to compliment the training and veterinary treatment.  After studying the available equine literature of the time she also studied massage for humans to extend her knowledge.

During 1970 to 1981 Helen traveled to Europe and studied with the Classical Dressage Trainer Egon Von Neindorff in Karlsruhe, Germany.  She is still a student of dressage in the classical form and is now training in the Phillipe Karl system.

Since developing her system of horse massage she has been teaching her techniqes for over fifteen years.  Helen has treated winning horses from Group 1 Racehorses, Grand Prix Dressage horses to 3* Eventers.  She has a passion for the complete rehabilitation, recovery and retraining of horses to gain optimum results in whatever field you aspire to.

Seeing infrared images of a horses leg in 1995 led to a "Eureka!" moment in 2000 when thermography again appeared in Jean Koek's life.

Then, as a EMRT™ therapist, she found thermography invaluable for giving progress reports to an abscent client.  The next ten years took her all over the world to study and work with this exciting but controversial diagnostic aid.  Presently, thermography is mostly used when regular diagnostic tools have failed!

Examples:

1.  FEI Dressage horse (Prix St. Georges Inter I) lame o/f six months following an arena fall.  Thermography showed o/f to be 11 degrees colder than n/f.  An amazing series of infrared images taken over an hour as a massage therapist (and NSW Dressage Team Manager) Jenny Carroll, worked on the horse, showed circulation returning.  Horse went Grand Prix in January.

2.  Pleasure horse owner was told by many that she was imagining a problem.  Infrared imaging during saddle fit assessment showed that horse was warming up on one side of her body only.  Veterinary chiropractic and acupuncture successfully addressed the problem.  Possible cause - post-birth problem.

Jean is currently involved in a variety of projects where thermography is one of the measurement tools.  Using video infrared to watch the body under stress in an ongoing love and she hopes to do further studies on the effects of the rider on the horse.

Jonathan Leoncini has been handling and riding horses since he was 12 years old.  With the love of horses very much a part of his life with endurance riding, it was there where he wanted to give something back to the horse, and more importantly to endeavour to rectify horses' problems.  Farriery was the answer.

He was one in seven apprentices who were the first group to complete a formal apprenticeship.  Jonathan's passion for horses has continued throughout his 25 years as a farrier.

He has competed in farriery competitions throughout Australia and has represented Australia at the World Blacksmiths/Farrier Championships in Calgary, Canada. Jonathan was recently invited to Malaysia to judge the Asian Pacific Farrier Championship, and also lectured there.

Jonathan's passion is strong as ever and he enjoys lecturing and giving the horse owner an understanding of what to look for in their horse's feet.  "Every horse is someones Phar Lap".

Laurie Paltridge has been shoeing horses for 17 years in the Western Districts of Victoria.  He obtained his 'Trade Certificate' in 1994.  He is based in Warnambool in Southern Victoria.

Laurie shoes a range of horses, including racehorses, eventers, show horses, pony club horses and ponies.  'Kibbutz' (who came 9th in the Melbourne Cup) 'Hissing Sid' (Warnambool Cup) and Arch Symbol (Wangoom HDCP) are among some of the racehorses whom Laurie shoes.

Alongside that, he does remedial work at Warrnambool Veterinary Clinic.  The Veterinary Clinic gets a lot of horses with feet and leg problems coming to Warrnambool to get trained on the beach.  This has allowed Laurie to see a wide range of hoof problems, which in turn has been a great learning experience in rectifying their problems.

Laurie is a great believer in furthering education and tries to attend as many farrier clinics as possible.  He also has his Certificate in Horse Management (MOFMC) and Certificate in Small Business (TAFE).

Joanna Robson, DVM, CVSMT, CMP, CVA, SFT is a graduate of the Washington State University Honors Veterinary Medicine Program.

Unable to find helpful professional resources, she determined to learn everything possible about a grounded holistic approach to pain-free performance and longevity in our horses, and to build a community of like-minded equine professionals.

Combining traditional veterinary medicine with veterinary chiropractic, veterinary acupuncture, Chinese herbal medicine, and the science of saddle-fitting, Dr. Robson’s goal is to provide integrated soundness solutions, and to educate the equine public about understanding and achieving the pain-free horse.

She has published numerous print and online articles about the effects of ill-fitting tack and the importance of correct engagement on the equine body and mind, and has an acupuncture case study pending for the Journal of Traditional Chinese Veterinary Medicine. Her focus is objectively demonstrating the before and after changes in equine movement following treatment and use of a correctly fitting saddle.

She is the owner of Inspiritus Equine Inc.  in Napa, California, and the founder of Intregrated Soundness Solutions (sm).  She found her way to her passion when her horse needed help healing from a back injury.

Maureen Rogers is a pioneer and leading expert in the field of Equine CranioSacral Therapy work. She is the founder of the Equine CranioSacral Workshops - an international education program which offers the most extensive program of study.  Her pioneering efforts have opened doors and changed lives of horses around the world.

Ms. Rogers travels internationally for teaching, lectures and private consultations.  She works with horses of all disciplines and her clients include competitive horses, Grand Prix showjumpers, to Olympic athletes through to novice.  Travelling year round, she brings her cutting edge principles to working with vets, equine physio's, farriers, equine dentists, horse trainers and owners world wide.  She is internationally sought out for her expertise in equine craniosacral work, rehab therapy skills and especially in treatment of conditions of headshaking, TMJ issues and biomechanics of the horse.

Her first DVD Hope for Headshakers - A CranioSacral Approch to Equine Health has sold copies worldwide and has opened doors for horses who suffered with this condition.  Maureen will be releasing her new DVD "Is it Posture or Conformation?" in November 2010 during her visit to EQUITANA.  She will also be offering her Equine CranioSacral workshops in November in Australia.

Books for Your Reference Shelf: "Principles of Farriery" by Colles and Ware

Welcome to Principles of Farriery by Chris Colles and Ron Ware. Published September 2010 in UK, November 2010 in USA. Shoe examples handmade by Billy Crothers. Specifications: 400+ pages, 8.5 x 11", full color throughout, hard cover with dust jacket, fully indexed. Price: $125 each plus post. Order by email books@hoofcare.com or call 978 281 3222. Fax orders to 978 283 8755. Full order details below.

Principles of Farriery by Colles and Ware is the first completely new farrier textbook and reference to be published in recent years. This major book is a timeless guide to the traditional practice of professional farriery and to the actual craft of shoeing horses. It describes hoofcare and horseshoeing in its bare-bones form: this book will work just as well in a third-world country as in an upscale hunter/jumper barn because it does not prescribe any special tools, products or procedures. It simply and elegantly describes the horse's foot and explains how a professional farrier would go about shoeing it--within various hoof balance or lameness scenarios--by using only the most straightforward tools and either common factory-made shoes or specific handmade shoes.

Horseshoes in the book were specially made by world champion Billy Crothers and were photographed to show both the ground surface and the foot surface. This open-toed bar shoe was used to show the difference in nail hole position between it and using a normal shoe backwards.

The book is written by two of the most accomplished and respected experts in Great Britain: a lameness-specialist veterinarian who is deeply involved in farrier education, and a hoof balance specialist farrier who is fascinated by the horse's foot and limb conformation.

An announcement has finally been made, and it looks like Principles of Farriery is on its way to the USA. Beginning today, Hoofcare + Lameness is accepting reservations for the first shipment of books, expected the second week of November. Update: As of 9 November, the first books are in stock and ready to be shipped!

I have been looking forward to this book for years. Colles and Ware worked together for many years; Colles brought the concept of hoof balance to the attention of the veterinary world in his papers on treating navicular disease back in the 1980s.  He is currently a senior partner in Avonvale Veterinary Practice, UK, specializing in equine orthopaedics.

Colles (shown right, courtesy of Avonvale Vet Practice) is recognized by the Royal College of Veterinary Surgeons as a Specialist in Equine Orthopaedic Surgery. He and Dr Chris Pollitt are the only two veterinarians I've ever heard of who have received the honorary Fellowship of the Worshipful Company of Farriers. Dr. Colles is also co-author with Sue Dyson of Clinical Radiology of the Horse and the useful booklet, Functional Anatomy of the Horse.

Ron Ware paused in his work at the Animal Health Trust forge in 1985 (or so) for this photo. Yes, he is very tall.

Ron Ware's Fellowship thesis on hoof balance for this FWCF qualification in the Worshipful Company of Farriers was the landmark paper for its time and one of the most important publications of the last 50 years in farriery.  He has always been one of the most highly respected farriers in Great Britain, although you've never seen him lined up at a contest and his name is not a household word. He is a farrier's farrier. He was for many years the resident consulting farrier at the Animal Health Trust in Newmarket, England, and also has had a relationship with the Hong Kong Jockey Club as a farrier adviser there.

Ron, in my opinion, is a sort of Zen master of farriery; he is someone who has thought very deeply and always shared his knowledge, yet he always focuses on the foot itself and the importance of limb conformation and his shoeing methods appear to be very simple and straightforward because he primarily addresses the foot, not the shoe. His reputation is above reproach in Great Britain, although he has been retired for several years.

I believe that this will be the first farriery book with a vet and farrier as co-authors.

The 400-page book is described by the publisher in this blurb: "The coverage starts with a brief history of farriery, then looks at the legalities of the job and how to control equines for trimming and shoeing. The authors describe the care and maintenance of the forge and farriery tools, as well as the anatomy and function of the horse, especially the lower limbs, the principles of foot balance, and the practice of shoeing. Shoe making, surgical shoes, lameness and shoeing are dealt with in detail, and the book is embellished with hundreds of specially taken photos, and explanatory line drawings."

The book is beautifully designed. Examples of shoes are made by world champion farrier Billy Crothers and are, as one would expect, suitable for framing! Comments about traditional (i.e. somewhat archaic) designs of British shoes are re-examined and critiqued in gentle retrospect of the 21st century, with explanations of why they were developed in the past, but their use on today's horses (assuming one has the skill to make these shoes) is evaluated in candid commentary.

What this book does not have: No Equilox, no Vettec products, no impression material, no glue-ons. This book could have been written in the past; it can stand the test of time and will still be relevant in the future as commercial trends change. I believe that this was done intentionally; I also believe that the authors' philosophy is to concentrate on the foot and keep the shoeing simple. Modern balance theories are not discussed or compared.

A sample page from the beautifully laid out and referenced Principles of Farriery by Colles and Ware; reserve your copy now!

For this reason, I also think that some people may be disappointed initially because the feet in the book do not look like they are shod in state-of-the-art products. All you see is hoof and simple steel and nails. That book on high-tech farriery is yet to be written, and look to Hoofcare and Lameness to keep you up to date on trends and new ideas in the meantime. Look to Principles of Farriery to be an anchor of a reference on axial hoof balance and core farriery wisdom.

Pollitt's Laminitis Images Have a New Look: MIMICS Software Goes 3-D

by Fran Jurga | 27 September 2009 | Fran Jurga's Hoof Blog

The cover of the Proceedings of the 2009 laminitis conference is a compilation of images of one foot of a chronic laminitis case from the University of Queensland in Australia. The foot's CT scans were converted to 3-D images using Mimics software and the expertise of Dr. Simon Collins of the Animal Health Trust in Newmarket, England. (Double-click on image for a larger view in a new window, but sorry that the web requires a low-resolution version of a very high-resolution form.)

When the end of the Fifth International Equine Conference on Laminitis and Diseases of the Foot comes, attendees might remember proportionately less of what they heard...and more of what they saw.

The heightened visual aspect of the exciting biennial conference, which will be held November 6-8 in West Palm Beach, Florida, may lie in the technology side of things, but the impact will be an eyeful that everyone can appreciate.

Leave it to Dr. Chris Pollitt (photo inset at left), assistant director of the conference, to bring the latest and greatest technology to the conference and to enhance his presentations.

The new software is called MIMICS; it is made by a Belgian company called Materialise NV. In a nutshell, MIMICS converts CT scans into three-dimensional forms. I've also seen it used to model a nasal cavity for a surgery case at Cornell's vet school, and for a comparative study of the soft tissue structures of equine feet at Auburn University. Dr. Pollitt says that MIMICS software is used extensively for human skeletal reconstruction surgery and prosthetic implant design and simulation.

"Suddenly I can 'see' an individual horse’s foot from all angles and can virtually dissect it on the computer monitor," Dr Pollitt wrote in the Proceedings.

MIMICS was introduced to Dr Pollitt and to the world of laminitis by British hoof anatomy researcher Dr Simon Collins. Dr Collins will be in Palm Beach to explain how he uses computer modeling in his work at the Animal Health Trust, where he collaborates with lameness experts Drs Rachel Murray and Sue Dyson. His images will be dazzling.

Dr Pollitt wrote in his introductory essay in the Proceedings, "Analyses of feet with chronic laminitis clearly show that distorted tubular hoof growth, lamellar wedge formation and solar loading of the distal phalanx are relentlessly destructive to bone. It behooves laminitis caregivers to understand the unmitigated, severe chronic process and develop proactive, early intervention strategies that will measurably arrest the process. MIMICS in the hands of laminitis scientists will aid this process."

Does anyone besides me see great irony in the way that Dr Pollitt over the years has created stunning visual images of the terribly destructive disease of laminitis? The quality of his images is always worthy of Scientific American or National Geographic and yet the subject is the disease we all dread. Thanks to his artistic eye we all know what laminitis looks like, even though it's the disease we'd most like to see wiped off the equine map.

NOTE: The deadline for registration for the conference has been pushed back to September 28th, since the mail has been so slow in getting the brochures and registration forms to everyone. Brochures were sent to all subscribers to Hoofcare and Lameness Journal. Also, a reduced rate for two-person registrations has been added. Visit www.laminitisconference.com for more information.

Hoof Research Road Show Premieres This Weekend: Pollitt-Hampson Laminitis and Wild Horse Hooves Headline in Australia

by Fran Jurga | 7 May 2009 | Fran Jurga's Hoof Blog

Dr. Pollitt is known for his hoof-related research but part of his ability to get people to listen is his dazzling imagery. These images are from a series of CT scans of a foot. (©Chris Pollitt/AELRU image)

A couple of weeks ago, there was a street scene here in Boston that was wilder than anything since the Red Sox won the World Series. U2 was in the town. That's not so unusual in itself--the band might play Fenway Park or some other huge venue and sell it out for three or four nights of legendary concerts.

But this was different. They secretly booked a tiny concert hall in the suburb of Somerville.

I can remember, vaguely, that the Rolling Stones did something similar years ago. They wanted to play a small, intimate little theater where they could see the audience and judge how the music was received.

The same thing is going on this weekend in the southern end of Australia, where Dr. Chris Pollitt and his PhD candidate assistant Brian Hampson are quietly opening a new series of lectures on laminitis and hoof research. They'll be at the University of Melbourne Friday, and in Tasmania Sunday.

Dr. Pollitt's been lecturing about laminitis for years, but his work now has the added synergy of the brumby (wild horse) research component, which in turn has been energized by some out-of-the-box thinking about domestic vs wild horses that will have all of us scratching our heads when we finally hear these lectures.

Dr. Pollitt's model foot begins with a MIMICS image, created in collaboration with Dr Simon Collins, Animal Health Trust, Newmarket, UK

There were gasps of apprehension when Dr. Pollitt stepped down as professor at the University of Queensland vet school, but the research world was pleased. Freedom from teaching would surely allow him to dedicate full time to his directorship of the Australian Equine Laminitis Research Unit, the world's leading center for laminitis research at the University of Queensland.

To everyone's surprise, something else happened. In addition to charging forward on the laminitis front with a collaboration with the Laminitis Institute at the University of Pennsylvania, he started a second research center, the brumby unit, designed to study the hooves of Australian wild horses so that he could finally come to understand how a normal foot is supposed to function.

For years, Dr Pollitt has said that his hands have been tied in laminitis research because he is trying to understand a disease mechanism in the foot without being able to compare it to the normal functioning foot because we simply don't have a good model of the normal foot.

So Pollitt and his research associate, Brian Hampson, and most recently with sidekick American veterinarian Dr. Donald Walsh of Missouri, have been trekking through the outback of Australia studying wild horses in wet, dry, rocky, sandy and even flooded terrain. They watch, they film, they tag, they camp, they bring volunteer research assistants, and they've collect data--volumes of it, none of which has been shared except in tantalizing tidbits until now.

Donald Walsh DVM of Missouri, president of the Animal Health Foundation in Pacific, Missouri, has been conducting laminitis research in Australia but rode out on brumby research expeditions with Pollitt and Hampson. Walsh has been studying wild horse feet in the USA; the Animal Health Foundation helps fund Pollitt's laminitis research. (Brumby Research Unit Photo)

Marg Richardson, a research team member of the Australian Brumby Research Unit, is one of the hosts for the lecturers this weekend and has organized the warmup tour.

She is particularly excited to be introducing Brian Hampson in his first official speaking tour. At the Australian Brumby Research Unit, Hampson is undertaking world-leading research by capturing and sedating brumbies, attaching GPS collars, tracking their movement and then recording the relevant data for herd groups. This includes what they are eating, the condition of their hooves and how much they are moving.

One of the marketing projects launched by the Australian Brumby Research Unit is making freeze-dried brumby feet available to other researchers.

Maybe, it turns out, to understand a lot about hooves we need to learn to a little bit about behavior. “Never has the saying of ‘No Foot No Horse’ been more obvious, when you see how much these horses move,” Hampson says. “We have tracked the movement of domestic horses in a variety of settings from the racing environment (to) five-acre paddocks (and) up to 10,000 acre paddocks to see the variation of movement and it has been quite staggering. Old brood mares turned out in paddocks are moving more over a 24-hour period than our elite race horses."

Dr. Pollitt's presentations will center on using computed tomography imagery to share the inside view of what happens to the hoof in laminitis and other hoof diseases, compared to normal hooves. Digital images from the CT scans, arranged in 3-D will also allow manipulation of the model to observe whatever tissue is of interest. Models will be shown for laminitis, side bone and normal feet.

A world tour is planned, of course; Dr Pollitt plans to speak at the 5th International Equine Conference on Laminitis and Diseases of the Foot in West Palm Beach, Florida, to be held November 6-8. See you there.

It sounds like Brian Hampson is ready for a world tour of his own.

I am not positive that places are still open in the lectures, but you can inquire. Please email Marg Richardson or phone (in Australia) 64 272255 or 0419 572255. Click here for a press release and links to flyers from the Equine Veterinarians Australia web site.
