Hello Dr.O and other folks,
Just wanted to clarify my concerns about my horse. A few days ago my farrier found some mild white line disease on my horse. I showed up at the end of session so I did not see the gunk he carved out of his hoof. It was on the lateral border of the RH towards the heel behind the nails. Shoe seems to be on very securely.
He told me to treat it with "Monistat 7" (over the counter yeast infection cream for women containing "miconazole nitrate 2% & 4%")
I have read Dr.O's article pertaining to treatment and my own vet will be out in a few days to check. I have been scrubbing out with betadine and a toothbrush and letting dry and the using the yeast inf. cream. I have "poked" into the carved out area and do not feel any soft areas at all.
I have posted a few pictures and am wondering if, even though it seems rather shallow, if more of the wall should be removed as Dr.O's article highly suggests..AND if I should be covering the area once treated to keep dirt out. I know the air kills the infection, but have read in a few books that this is sometimes suggested.
My farrier stated that many tests results have shown a number of bacteria's called WLD but the one thing they have in common is yeast.
Any thoughts are appreciated while I wait for my vet.
Thanks,
IKE

Hello IKE,
I really cannot say if this hoof has been pared out enough because I cannot see the areas affected by WLD. The image is a little confusing as it appears to me the horn of the wall is split out and does not expose the WL but a deeper layer of the wall. Toward the heel there is a small deeper defect that may be all the way through the wall. These areas do not look pared out so much as broken out.
Miconazole is an interesting choice for treatment. If the particular fungi responsible for your horses problems are sensitive this may be effective. I have not seen sensitivity studies on these horse isolates. Some keratinolytic fungi in humans are sensitive to miconazole. If you have continued problems and you assess the areas have been pared out properly consider switching to our recommendations which are very broad spectrum.

Hi Dr.O,
Thanks for your response. I am also thinking the vet may want to pare out more of the wall. The defect you see towards the heel was an old bang that I have been watching grow out, but is probably worthy of some probing by the vet.
Am I to understand correctly that you recommend a 10% formaldehyde solution (after further paring out) (assuming I see no bleeding from sensitive tissue, which I have not) daily for 3 weeks then 1x a week until wall grows out completely?
Where does someone purchase formaldehyde?
Many Thanks!
IKE

OH!! One more thing...Are Radiographs typically used to diagnose the extent of WLD? I had read that in ONE book on horse health.
Thanks again

Ike, I continue to use the recommendations in the article. As to the formaldehyde it is usually available through your veterinarian. Though more expensive, the over the counter product "Thrushbuster" is a 10% solution. For more on this see Treatments and Medications for Horses » Antibiotics and Antimicrobials » Formaldehyde and Formalin Use.
Radiography might pick up the proximal extent or infiltration in the WL area caught in profile on the radiograph, it will completely miss the areas not in profile. That is not the biggest reason you don't radiograph WLD however. You don't because it provides you with no useful information: you pare it out till it is gone. If you don't it will continue to infiltrate and undermine the wall.
