Term | Definition |
the result of acute renal failure in horses is | toxic causes, certain medications are commonly indicated (antibiotics/NSAIDS). breakdown product of RBC (hemoglobinuria) and muscle (myoglobinuria) can cause renal failure also. |
signs of acute renal failure include | oliguria (decrease in urination), anorexia, and changes in urine concentration, elevated serum chemistry levels |
urotliths, urinary stones are most commonly found in | the bladder but can also be found in the kidney, ureter and urethra |
stones are composed of | calcium carbonate or calcium phosphate; more common in geldings than mares |
PU/PD can be due to | physiologic causes,. including lactation, heat, exercise, diarrhea, and glucocorticoid administration, certain diseases (cushings), behavioral problem, diabetes, renal failure |
equine dermatophytosis | ringworm a fungal infection of the superficial layer of skin. "bull's-eye" appearance with hair loss caused by Trichophyton and Microsporum |
Dermatophilosis is a bacterial infection caused by Dermatophilus congolensis | rain rot or rain scald - crust are usually pulled out with a tuff of hair leaving a lession yellow in appearances |
rain rot is most common in winter and spring because | organisms like to colonize wet, macerated skin. organisms form a double cocci chain "railroad track" appearance under microscopy |
a syndrome characterized by mane and tail rubbing develops into an allergic pruritic skin condition secondary to the bite of | Culicoides flies, Culicoides hypersensitivity |
body regions affected by culicoides in clude | face, ears, mane, withers, rump, base of tail and ventral abdomen |
horses should be moved away from ponds, lakes or irrigation canals because | culicoides breed in stagnant waters |
the ways to decrease culicoides are | stabling with doors and windows closed, use of fans and insecticides and repellents |
a benign locally invasive tumor of the skin, the most common tumor in horses is | equine sarcoid-raised hairless lesions with a corrugated surface often bleeding when |
raised hairless lesions with a corrugated surface that often bleed when traumatized | fibroblastic sarcoids |
a flattened form sarcoid | verrucous sarcoid |
treatment for sarcoids is usually | surgical resection, cryotherapy, laser therapy, immunotherapy, radiotherapy and chemotherapy |
common skin tumors particularly in grey horses | melanomas |
treatment of melanomas is | administration of cimetidine, or autologous vaccines (vaccines made from the horse's tumor), surgical removal if it interfers with tack or normal body functions |
the most common cause of blindness in horses is | equine recurrent uveitis (moon blindness) |
moon blindness is | an immunemediated condition (many things have been blamed on its presence, ie heredity, parasites etc) |
clinical signs of moon blindness include | episodes of intraocular inflammation, swelling of the eyelids, corneal edema, and hypopyon (inflammatory cellular exudate in the anterior chamber) |
over time the episodes become more frequent and more severe and produce permanent ocular damage including | retinal degeneration, cataracts and adhesions of the iris to the lens or to the anterior chamber (synechiae) |
moon blindness is treated with | long term anti-inflammatory therapy opthalmic and systemic. preparations containing atropine and corticosteroids if no ulcer is found |
corneal ulceration commonly results from | ocular trauma |
in some instances ulcers are colonized by fungus | Pseudomanas or Aspergillus - causing a "melting" corneal ulcer that is rapidly progressive and can result in rupture of the globe |
