Smoke and your Horse
 Healing with Honey
Hello everyone,
                We all recognize this reality living in the dry high desert. I took this picture standing next to the horse trailer, preparing to evacuate horses from a client’s property. In the aftermath of emergency evacuation, a microchip can play a crucial role in reuniting horses and owners. Pease consider microchipping your horse this fall, and read more below about caring for your horse when faced with environmental heat and smoke challenges.
               
I am here to serve you and your equine companions, with over 25 years experience, and a profound commitment to building healthy partners,
Dr. Chrysann 

Fall Clinic Schedule
Routine Fall exams include flu/rhino vaccination plus deworming or fecal examination, an oral exam, and sheath cleaning.  Also consider Microchipping!
To reserve an appointment, call 775 969 3495 with:

Healing with Honey

Wounds, especially those located below the  knee or hock, are notorious sources of frustration for horse owners and veterinarians alike. Understanding how wounds heal is the first step in designing an appropriate wound management plan; choosing a wound dressing that supports the body’s healing mechanisms is second.

1)       Immediately after a wound occurs, the body begins its own clean up process.  White blood cells migrate into the wound to eliminate foreign material, dead tissue and infectious agents. These cells exit the wound as pus.  PUS IS A NORMAL, HEALTHY RESPONSE TO A WOUND IN THE FIRST FEW DAYS.  It is important to keep the wound environment moist in this early healing period.
2)       Once the wound environment is clean, and dead tissue has been removed, the next healing phase involves rebuilding tissue.  The body builds a scaffold of collagen, and delicate new skin cells and blood vessels climb along this framework, repairing the wound defect.  During this phase, the wound should be protected from invasion by secondary bacteria, and inflammation should be minimized.
3)       Finally, the body spends a long time (months in severe wounds) strengthening and remodeling the fragile young tissue that has filled the wound.  Now it is important to keep the tissue pliable and soft with emollient substances like lanolin.
Our job is to enhance the cleaning and restructuring phases to decrease time to wound closure, improve cosmetic outcome, and avoid problems with exuberant granulation tissue (proud flesh) and wound infection.  This is where honey can be uniquely useful.  Honey is a biologic wound dressing; while each of its beneficial properties can be found individually in pharmaceutical products, only in honey are they all present together working in cooperation to enhance healing while maintaining a moist wound environment.
How does honey work? The high sugar content of honey draws water out of wounds and reduces edema (fluid swelling).  Honey is slightly acidic, which inhibits bacterial growth and acts with the high sugar content to pull water out of bacterial cells. Honey from Manuka trees in New Zealand has additional unique properties. Researchers at the University of Sydney studying the efficacy of Manuka honey in equine wound healing reported that Manuka honey treated wounds had healthier tissue regrowth, which they believe is related not only to its unique antibacterial effects of the honey, but also to Manuka honey’s positive influence on the horse’s immune system.
All types of honey possess beneficial wound healing qualities. The antibacterial activity of most honey’s is due to the presence of hydrogen peroxide, which can be inactivated by enzymes normally present in the healing wound. In contrast, the antibacterial component of manuka honey is a small water-soluble molecule, methylglyoxal, that diffuses easily through the wound environment, and is resistant to enzymatic degradation. This compound also penetrates the biofilm which forms in wounds, protecting bacteria from the action of many systemic and topical antimicrobial agents. Finally, Manuka honey is available in sterile, medical grade preparations. Non-medical grade honey often harbors bacteria that are not dangerous when used for food consumpution, but which can colonize wounds causing secondary bacterial infections.  For all of these reasons, medical grade Manuka honey products are the safest, most effective choice for wound treatment.

We recently used Manuka honey on this chronically infected hoof following a hoof wall resection. The healing of the disrupted coronary band was rapid and the integrity of the coronary band was completely restored.

Smoke and Your Horse

Smoke is an unhealthy combination of carbon dioxide, carbon monoxide, soot, hydrocarbons, and other organic substances. Smoke particulates can irritate horses’ eyes and respiratory tracts, and hamper their breathing.

The simplest thing you can do to limit the damaging effects of smoke on your horse’s airway is to limit your horse’s activity when smoke is visible.   Increased airflow and turbulence that accompany athletic activity can significantly increase the inflammation and damage to delicate cells lining the respiratory tract. In addition, if possible, misters and fans can be used to improve air quality in your horse’s environment.

Human air quality advisements can be applied to your horse as well.  If your eyes are burning and you smell and taste smoke, then assume that your horse is feeling as uncomfortable as you are.

Most importantly, when smoke has been particularly heavy, remember that it takes time for airways to recover fully. Four to six weeks can be required for airways to recuperate from severe smoke exposure, and early return to exercise can delay healing and increase the risk of long term airway damage.

The best way to combat heat and smoke is through hydration. You can:
  1. Provide clean, fresh water at all times
  2. Water your horse’s hay and feed grain as wet mashes
  3. Put sprinklers out in turn outs to reduce dust and smoke and increase moisture in the air

Spring 2015 News & Notes:
Ø Vaccination Clinic Schedule
Ø Veterinary Networking and Referral
Ø Adverse Vaccination Reactions
 
Here we are again, moving into a new year.  I hope everyone is healthy and ready to ride!
After this VERY warm, VERY dry winter, both plants and animals may be subject to unusual disease patterns this spring. Vaccination against vector borne diseases such as West Nile Virus will be particularly important this year, and I strongly recommend a fecal exam on every horse to identify those infected by overwintering parasites.
Consult the clinic schedule in this flyer, and call to confirm your appointment today.  I will see you then!
Building Healthy Partners,
Dr, Chrysann

Veterinary Networking & Referral
     Last week a veterinarian called me for consultation on a horse he had diagnosed with equine metabolic syndrome.  The veterinarian had some questions about the horse’s latest laboratory values, and how to move forward with a treatment plan.  I offered my interpretation of the horse’s laboratory results and made some suggestions regarding treatment . The veterinarian called me because I am a diplomate of the American College of Veterinary Internal Medicine, which means that after receiving my veterinary degree I successfully completed a 3 year clinical residency training program and a rigorous 8 hour examination process and case report publication to ensure my advanced knowledge and experience diagnosing and treating internal medicine problems.     

     On the flip side, I called my friend Dr. Robert Hunt for advice on a yearling with an atypical stifle lameness.  Dr. Hunt is a diplomate of the American College of Veterinary Surgeons and resident surgeon at Hagyard-Davidson Magee in Lexington, Kentucky. Bob and I discussed the case as he examined the digital xrays I had emailed him. He gave me his opinion on the radiographic changes and some suggestions on treatment options. 

     This type of congenial exchange of information goes on, often without your knowledge, as a routine part of your animal’s veterinary care. The variety of problems presented to the ambulatory equine clinician is enormous, and maintaining this network of colleagues is a critical part of my service to you.  After 27 years as a practicing veterinarian, the majority of patients I see exhibit clinical signs with which I am familiar, and diagnostic and treatment plans are frequently routine.  However, when an animal presents with a complex complaint outside of my expertise, I do not hesitate to seek consultation.  Sometimes the initial conversation with a specialist leads to the referral of the patient for advanced diagnostic evaluation.

     Helping you decide when to refer a patient is an important part of my job.  You should never feel awkward asking for a second opinion from a specialist - I am here to help you find the most effective plan to return your horse to full health and athletic activity .   Following referral for advanced diagnostics and evaluation by a specialist, your horse will return to my care for ongoing treatment and rehabilitation.  By asking me to make the initial contact leading to referral, you insure that any diagnostic findings, as well as my clinical notes, will be part of the information that will accompany your horse to their appointment.   

     There are 21 specialty colleges of veterinary medicine recognized by the American Veterinary Medical Association! In the greater Reno area we have 2 board certified equine surgeons, 1 large animal internist (yours truly!), and a board certified ophthalmologist who sees both large and small animal patients.  UC Davis is 3 hours away and offers specialists in most of the large animal disciplines.  To learn more about veterinary specialists, google AVMA specialty organizations.
 

Adverse Vaccination Reactions –
What you Should Know

 Every spring I administer over a thousand vaccinations by deep intramuscular injection. I  field approximately 5 calls (< 1.5% of horses vaccinated) with reports of adverse vaccination reactions.  In my 27 years of veterinary practice, I have seen 3 true allergic/anaphylactic responses to intramuscular vaccination, and one serious vaccination complication associated with intranasal Strangles vaccine. Vaccination is a safe, effective way to protect your horse against disease. However, you should be familiar with adverse vaccination reactions, and how to respond.


By far the most common adverse reaction to vaccination is the simple sore neck. The day after vaccination you may notice that your mare is unwilling to move her head, and she exhibits pain and swelling at one of her vaccination sites. Occasionally the discomfort will be so severe that a horse will not lower their head to eat or drink, or will pull back if pressure is applied to a lead rope when they are haltered.  These inflammatory reactions typically resolve within 48 - 72 hours with treatment including warm compresses, offering food and water at a comfortable height, and administering non-steroidal anti-inflammatory medication.

This "sore neck" reaction is NOT an allergic response to the vaccine. True allergic responses occur immediately, or within minutes, of vaccination. Rather, these are exaggerated inflammatory responses to the ingredient in the vaccine that stimulates the horse's immune system.  Called an adjuvant, this ingredient amplifies your horse’s response to the vaccine’s disease organism.  The ideal adjuvant is a potent stimulator of the immune system but does not cause severe local soreness. Unfortunately, individual horses may respond unfavorably to the adjuvant in specific vaccine brands or antigen/adjuvant combinations.

When a horse develops a sore neck after vaccination, it is important to notice whether or not the horse is systemically ill.  Specifically, is the horse eating and drinking? Does he have a fever? Is the swelling at the vaccination site severe and increasing? If your horse has an adverse vaccination reaction, I recommend that you contact your veterinarian with this information in hand so that an accurate decision can be made concerning the need for treatment.

 

Clostridial myositis is a rare, serious complication following intramuscular injection. Clostridial bacteria exist normally in the environment in a spore form.  Even when a clean needle and syringe are used and an injection is administered correctly, it is possible for the needle to carry Clostridial spores deep into the muscle tissue.  These bacteria then grow rapidly, releasing toxins into the horse’s bloodstream. Clostridial infections at injection sites are rare, but can be life threatening and require prompt and aggressive treatment.

   Amanda & I look forward to seeing you in March!

Equine Dentistry: Why? When? How?

Why?  Because horses are no longer grazers.

Many of you have asked me “how do the Mustangs survive without dental work?” Here’s the answer: they chew more. The equine tooth evolved some 25 million years ago in response to changes in the earth’s vegetation. Available forage went from soft leaves to tough, fibrous grasses. In order to adequately break down this material, the horse developed hypsodont teeth, which erupt continuously throughout life. Each tooth is worn down by rubbing against an opposing tooth, creating an ever changing biting surface with ongoing wear of these surfaces determined by the horse’s diet and chew cycle.

Three factors contribute to wear of the horse’s teeth: the interaction between the two biting surfaces, the time spent chewing and the nature of the material being chewed. Research has shown that horses at pasture chew more and with more lateral (side to side) motion than horses fed a mixed hay/grain diet. Specifically, horses eating hay chew 58-66 times per minute vs. horses at pasture which chew 100-105 times per minute! In addition, horses eating a hay only diet take 16 hours to chew their daily ration while those on a hay/grain mix diet only need 6 hours to chew  their daily feed.

So our performance horses chew slower, for less time, and less effectively than their mustang counterparts. Therefore, they don’t do a good job of floating their own teeth, and small dental abnormalities that would self-correct on a tough grass mustang diet become serious dental issues without regular dental care in our horses living in confinement.

When? Once a year beginning at 2 years old.

Prevention is the key to healthy dentition as your horse ages.  Because their teeth erupt throughout life, and very few horses are born with a perfectly balanced bite, small imbalances become BIG imbalances as years pass.  The horse only has so much tooth, and with advanced age each tooth pushes to the surface and eventually falls out.  The most common occlusal problem encountered is a wave mouth, where the biting surface becomes a roller coaster ride instead of a level grinding plane, with some very long upper teeth opposed by very short lower teeth. The only way to correct the wave is to shorten the longer teeth. It can become impossible to achieve this in older horses with limited remaining tooth and poorly maintained bites.   EARLY AND REGULAR  dental care are the keys to healthy teeth as your horse ages.  If you wait until you notice weight loss, difficulty chewing, or dropping food (quidding) to have your horse’s teeth examined, it may be too late.

 

How? Dr. C prefers hand floats!

During a tooth float  Dr. Chrysann will carefully reduce any dominant teeth and level the chewing surface with a titanium coated tooth float. Dominant teeth create and are created by abnormalities in the chewing surface, or dental arcade which worsen over time and impede chewing and normal jaw movements. Some common configurations she may correct are hooks, ramps, transverse ridges and a wave which is caused by multiple dominant teeth. She will then adjust the alignment of the incisors, as small changes in the incisors will make a large difference in the occlusion at the back of the mouth. The specialized hand floats which Dr. Collatos uses are exceptionally sharp, and allow her to carefully balance each tooth in the mouth individually.

The use of motorized dentistry tools has become common in equine practice, and these tools are necessary in some cases of neglected mouths with severe bite abnormalities.  However, in the regularly maintained mouth, the use of motorized tools is unnecessary, and can cause permanent damage to teeth.  Prolonged grinding with motorized dental tools can create intense heat due to high rotational speed. Research studies have shown that temperatures reached with high speed (12,000 rpm) motorized floats can destroy dental pulp cells with resulting permanent damage to the tooth.  In addition, it is very easy to “overfloat” or remove excessive tooth material, with motorized tools.  Horses teeth are NOT smooth or rounded naturally, and the tearing and grinding action of normal anatomical sharp borders are the essential first step in the digestive process.

When performed correctly, the goal of equine dentistry is to balance the horse’s bite while leaving the natural contours of the tooth intact. This ensures longevity of a functional bite as your horse ages, reducing the need for costly senior diets.  It also allows free movement of the temporomandibular joint (TMJ) which insures not only correct chewing of food, but correct alignment of the head and neck.  Hock soreness and back pain can be the result of a poorly balanced mouth in performance horses!

TCVM – Are you a believer?

Dr. Chrysann is learning the practice of Traditional Chinese Veterinary Medicine (TCVM), with an emphasis on Acupuncture.  Does it work in horses? Yes, it does, when performed correctly, with an accurate and appropriate diagnosis.  TCVM is based on the ancient concept that energy follows specific anatomic pathways, called meridians.  Meridians have now been mapped using modern scientific methods.  If a radio signal is introduced at one acupuncture point, it accumulates at other points along that  meridian, but NOT at points on other meridians.  Also, MRI brain images have shown that pain related acupuncture points activate specific pain-associated brainstem regions, while sham points do not.  Join Dr. C in expanding our ability to keep our horses healthy  and comfortable by using TCVM and acupuncture.
