* HRCC Report - October 2002

For the period April - October 2002

The work of the committee continues. Thank you to the   researchers and coordinators for their work, reports   follow:

Coordinator Reports:

Eye Disease - Coordinator Pam McDonald
  Since my last report I have had only one inquiry regarding eye   diseases. This person contacted me via the CTCA website so this   continues to be a good source of information.

It is my understanding that the Detroit club is trying to   schedule an eye clinic with Dr. Petersen Jones

Orthopedic Diseases - Coordinator Dr. Kydee   Sheetz
  There have been few inquiries regarding orthopaedic issues in   cairn terriers since my last report. The most commonly   addressed conditions include subluxing patellas and Perth’s   disease. There appears to be a significant number of breeders   in the US and abroad trying to blame the owners for these   inherited conditions stating that the owner must have somehow   caused their dog’s problem. Needless to say, this is   disconcerting for the owner. Education of breeders and owners   about the heritibility of these and other orthopaedic   conditions continue to be important.

MCND Multisystemic Chromatalytic Neuronal   Degeneration - Coordinator KathyVanWie
  No cases of this disease have been reported in the last   year.

CAVM (Complementary & Alternative Veterinary   Medicine) - Coordinator Cynthia Sherman
  Nothing to report at this time.

Skin Diseases - Coordinator Cindy Sushak
  For the reporting period August 2001 through August 2002, I   have received 19 requests for help with skin related problems   in Cairn Terriers. All requests received my standard letter and   I sent those interested a copy of the article on RAST and ELISA   allergy testing methods I wrote for the CTCA newsletter.

In 14 of these dogs, the problem was described as recurring.   All requesters had been to see a veterinarian and most had   limited success after common allergy treatments such as   steroids and antihistamines.

The outcome of the problem situation was learned in three   cases. Oatmeal shampoo combined with aloe gel applied directly   to sores relieved one dog’s symptoms. Benzoyl peroxide shampoo   and conditioner gave relief to another, and the third responded   to steroids and no more table treats.

There were no request for a referral to a specialist. The   complaints were common ear pain, itching, scratching, paw   licking, and loss of hair. The age range was 0.8 - 11 years,   average 4.5 years with two ages unknown. Eight of the dogs were   six years or older and 11 dogs were five years or less. There   were 9 males, 8 females, and three unknown sexes.

Heart Diseases - Coordinator Floyd Kuntz
  No report at this time.

VWD (vonWillebrands Disease) - Coordinator Clare   Redditt
  No additional information. Research has not been funded.

HRC Library  -Coordinator Pam McDonald
  In process of development

Kidney Disease - Coordinator Ruth Barstow
  During this reporting period two requests were received: 1. A   call from India by owners of a Cairn with chronic renal   failure. They wanted to know if they should do more than follow   the veterinarian’s recommendations to place the dog on a kidney   diet, monitor fluid intake and exercise and to take the   ergthropoetin as prescribed. 1 told them that it sounded as if   they had a good “vet,” and that the only other ingredient would   be a lot of love and attention, which 1 was certain they were   providing. 2. A call came from two breeders, both of whom were   inquiring whether or not the absence of one kidney in a cairn   was a genetic defect or gestational incident.

Unfortunately, the literature and the veterinarians who were   consulted were not conclusive. One veterinarian said that one   couldn’t inherit one kidney and the other said that the problem   was definitely congenital and the literature left one with   doubts!

In any case, the two breeders each supported different   viewpoints. They are both very responsible breeders and have   shared breeding programs and wanted to know how or if they   should modify their programs. Two of the bitches, although   apparently very active, happy and in apparent good health were   discovered to have only one kidney. The defect was discovered   because one bitch developed a pyometria and diagnostic efforts   revealed the absence of one kidney. The other bitch as a puppy,   was drinking a lot of water and urinating excessively and was   taken to the veterinarian for urinary function tests and the   absence of the kidney was discovered.

Now, at 14 months, she is housebroken and a happy Cairn.   (This demonstrates that animals as well as humans can live   quite well with only one kidney.)

In reviewing breedings, none of the sires has a history of   renal problems; however, the dam is common to both of the   bitches with one kidney. None of the other puppies born to her   have demonstrated problems and as far as we know none of the   sires have produced Cairns with kidney defects. The dam will be   examined a week from the time this report is written and we   will know if she has both kidneys. If she does, one may   conclude that somehow a gestational defect occurred and it   could be related to environmental factors (a crematorium is   located nearby) or that some sire or dam in the lineage,   without known disease, could have contributed to the defect.   disease, could have contributed to the defect. In any case, one   can recommend that with the next breeding, if it occurs, that   an outcross be used. If she has only one kidney, she should not   be bred again. Unfortunately, we will not be certain of the   cause, but precautionary measures should be taken.

GCL (Globoid Cell Leukodystrophy) - Coordinator Clare   Redditt
  Dr. Wenger reports that there have been 21 more dogs tested   bringing the total to 532. Of the additional samples, 3 were   found to be carriers. The carrier total now is 89 bringing the   percentage of carriers down to 16.7% of cairns tested. The   percentage of carriers is decreasing, however, carriers are   still being found so testing should be continued on those dogs   that have unknown status for GCL.

GDC (Genetic Disease Control) Registry - Coordinator   (in process of being filled)
  The GDC is no longer in business. The historical data has been   merged with OFA (see article in the Fall CTCA newsletter for   explanation).

CTCA Website - Updating HRC information is in   process.

CMO (Craniomandibular Osteopathy) - Research Project:   See attached report from Dr.   Patrick Venta, Michigan State University.

Ocular Melanosis Research - See attached report from Dr. Simon   Peterson Jones, Michigan State University.

PSS (Portal Systemic Shunt) Research Project -   Project has been cancelled. See attached letter from AKC Canine   Health Foundation for explanation.

This is the progress report from the committee and its work   for the past 6 months. Any Questions can be directed to the   chairman and a response will be made promptly.

Respectfully submitted,
  Clare Redditt, Chairman
