A New Clinic

The University of Minnesota’s Leatherdale Equine Center is a brand new clinic – very high tech with a lot of cool new toys. These new toys include a water treadmill for horses and a gait analysis system that helps in the diagnosis of lameness. It includes pressure plates and high speed digital cameras to help measure the amount of pressure a hoof has while it is landing and the angles of the joints of the landing and uprising leg. Very cool!

Check out the new center here —> University of Minnesota’s Leatherdale Equine Center

Speaking of new clinics I also need to mention that I have started working at a new clinic myself. Sorry small animal only – I have begun working at Oak Hill Animal Clinic in Crown Point, IN. I am there on Tuesdays, Thursdays and some Saturdays. So if you have a dog or cat in need of my services please do not hesitate to call and schedule an appointment at  219.663.7515

Streptococcus myositis – A Strangles vaccine reaction

I have been saying for years that the majority of horses do not need a Strangles booster. In fact, I have been telling people that many times the reactions are just as bad as the disease itself. Well I have seen my first case of vaccine induced Streptococcus myositis. I wish I could tell you that I diagnosed it; however it was not a simple cut and dry case.

My client just purchased this horse about one month ago in Tennessee. A strong healthy horse when he bought it, he trailered it home after spending a week with it on trail. Within the first week the horses head swelled just primarily around the nose. Since I am friends with this individual he called me up wanting my opinion (he knows I no longer do traditional medicine but he values my opinion). My initial thought was trauma, but over the phone I could not rule out an allergic reaction. When I examined the horse I was positive it was trauma (WRONG, but hindsite is 20/20 – LOL), the horse had bleeding from the nostrils more on the right side than the left and swelling almost exclusively to the nose area and more to the right. It looked like the horse had smacked its nose against something. Also the right hind hock was swollen almost looking like a capped hock. So my thought was that the horse was cast and struggled to get up hitting its hock and nose. The horse would be fine.

A few days later I receive a call from my friend saying the horse is colicking! OK so we went through the treatment for colic. BTW my friend is a small animal veterinarian so he does most of the treatments himself with a little guidance. He was walking the horse, but as I told him walking has been proven not to do much of anything except for tiring a horse that is trying to recover. If your horse while colicking lies quietly there is no need to walk him, you may reduce the chances of recovery by causing exhaustion. Vets now use walking to give the owners something to do while we are on our way ;) Now of course if your horse is thrashing on the ground it is important to get the horse up and moving to prevent head and body trauma, but otherwise just leave the horse lie quietly rousing him every 20 or 30 minutes to check gut sounds, gum color and heart rate.

Back to our horse… a couple hours later a call comes to me stating that the horse is urinating blood – hematuria! WHOA – if you did not listen to me about not walking the horse you better listen now – STOP walking the horse. Your horse is tying up and it is uncomfortable thus looking like a colic! My friend drew some blood and sure enough the horse is tying up otherwise known as Azoturia. OK so I thought this confirms my diagnosis of being cast, but one thing sticks out like a sore thumb why did the horse tie up days afterward and not the next day. It kind of didn’t make sense. The blood work also showed a slight anemia – where is that coming from?

Well what happened next threw another monkey wrench into the whole works, but you’ll have to wait until tomorrow for the rest of the story.

Oral Hyaluronic Acid – a change of opinion?

Oral preparations of Sodium Hyaluronate or Hyaluronic Acid (HA) are marketed as a joint supplement. One of the original HA products was Legend (trademark by Bayer) and was only available in intra-articular injection (joint injection) or intravascular injection (IV) forms. Intra-articular injection has been shown to be more effective however with the risk of joint infection and the inconvenience of having to have a veterinarian perform the procedure plus the added cost, IV injection seemed to be the way to go, especially after the Colorado State University study in 1997 that should that intravenous injection of HA decreases inflammatory mediators in the joint and improves lameness. For study info Effects of intravenous administration of sodium hyaluronate

Then came the oral administrations and intial results were not that great with many horse owners saying that there were no signs of improvement. It was surmised that in order of preference for using HA intra-articular injection was better than intravenous injection which was better than oral administration. I have been promoting that mantra for a couple of years now.

Well along comes a study from Rood and Riddle last year…Oral hyaluronan gel You can click on the link to the abstract of the study but let me quote for you the Conclusion of this study…

“CONCLUSIONS AND POTENTIAL RELEVANCE: Oral preparations of hyaluronan are being used to treat joint disease in horse. Anecdotal reports supporting the efficacy of these preparations already exist. This study provides objective evidence that oral HA reduces joint effusion post operatively following the arthroscopic removal of an OCD lesion in the tarsocrural joint.”

Which means that oral HA does have some effectiveness and is better than what I had initially thought. With that said it is still expensive in comparison to other oral joint supplements and the studies have not been conducted to determine if it is any better than other supplements or better than injectable HA. I know it is not better than Adequan as the research on Adequan suggest some cartilage rebuild where as HA does not.

So for those of you that I have told you are wasting your money that is only partially true…it does seem to work but I am still on the fence as far as cost effectiveness.

I think I am going to go through all the joint supplements and explain each one in the next few posts. Leave feedback in my comments if you have a request on what joint supplement you would like to know about and don’t forget to check out my website E-VetClinic
