small animal Flashcards
heart worm tests
direct - blood smear for microfilaria
and indirect for occult tests antigen of gravid females l3-l5 l6
cats only tests exposure not infection and rads have double lined echo density
immiticide- pyrental
kills l5 tarting l6; is harsh on body of animal, wolbachia needs to be treated for 1 month prior to starting imiticide
dirrofilaria immitis
organism transmitted by mosquitos, the mosquitios pick up microfilaria in blood and develop into l3/l3 then are depositied onto skin and migrate into vascularization
PP= 5-6 months
worms live
in main pulmonary artery and right ventricle
clinical signs
dysnea, exercise intolerance, cough ascites (CHF right)
cats= HARD asthma pulmonary signs or neurologic and shock
heartworm tx-
first kill wolbachia with doxy then do immiticide malarsomine injection then keep overnight and 4-6 weeks 2 injections 24 hours apart
cats have it kill them because allergic to malarsomine
oral heartworm
ivermectin(Heart gerd) and milbemycin (sentinel)
topical- revolituon (selamectin) and advantage multi
mast cell tumors
most common malignancy common in boxers bosons pugs brachycephalic - less aggressive lower grade tumor
release histamine and heparin
mast cell other signs
associated with go ulcers, bleeding poor wound healing,
grade shows level of aggressive ness- grade not detemerined by cytology
FNA or biopsy
eosinophils are abundant
treat with surgery 2-3cm excision
supportive- h2 blocker fa motidine rantidine or h1 dphyhydramine
mast cell tx
surgical incision, chemo or h1/h2 blockers vinblastine CCNU and alkylating agents , tocenarib or palladia
px- based on breed rate of growth grade KIT mutation size location, mitotic index
feline core vaccines
FVRCP- panleukema, rhino, 6 wks of age then 304 ws until 16 weeks then 2 doses 3-4 weeks apart 1 yr after users then 3 years every time after
calici,
rabies- 1 or 3 yr
FELV- leukemia non core with FIV - antibodies can interfere with other diagnostic testing
skin disease
FAD- number one caudal half of the body
atopy- seasonal ages 1-3 face paws extremities
Food AD- allergic dogs less than 2 same as atopy
OA
very common in dogs and horses- chronic progressive - older dogs
-steroids contra
-selective cox 2 inhibitors used
-will see joint pain, effusion, fluid, local inflammation, sclerosis, collagen disruption, loss of articular cartilage
tx- maintain body weight
use cox2 inhibitors but be careful with GI ulcer
carprofen, firocoxxib, deracoxib, meloxicam
steroids contra becuas inhibit metalloproteinase inhibit inflammatory cytokines- may thin cartilage
- joint supps- PGA= adequan, glucosamine and chondroitin sulfate cosequin and HA lubricant
oral melanoma
most common oral tumor malignant
common in golden, choes poodles spaniels, sometimes contain no melanin can look like round cell tumor
-mets to local lymphnodes - can also be found on nail beds
biopsy- and stage-minimum database regional LN aspirates and thoracic rads
-surgical incision with wide margins and useful with radiation therapy
- mostly use carboplatin and cisplatin
-human vaccine can be used for after is develops because tyrosinase is a human protein
-tumor size-px-<2cm better prog median survival 5.5 months if > 2 rostral is better prog than caudal
osteosarc
most common primary bone tumor in dogs
-large giant breed dogs and metaphysical region- does not usually cross joints - away from the elbow toward the knee - can mets to lungs
-amputition is best treatment control
-see in rads- lytic lesions- interrupted periosteum diaphysial can be a secondary of another type of cancer
FNA results in reactive bone US guided
pulmonary mets check for
-nuclear scintigraphy-bone scan
ELEvated ALP
-can do limb sparing but chronic resistant infections result
radiation can be palliative chemo= cisplatin or carboplatin and doxorubicin or adriamycin and biophsophonates
4-6 months with ampuation and 10-12 with chemo and surgery and 1-3 if mets
LOCATIONS- mandible ( best prog) , maxilla, scapula, ribs, spine, pelvis
parvo
enteriti in unvaccinated dogsor puppies, bloody dia, intususection, luekopenia - bleach is only cleaner
-take fecal ELISA
-CPV-2- fecal oral
long lived and resistant -fomite transmission- rapidly diving cells like crypts of intestines
luekopeniaa fever diarhhea vomitng
tx-supportive- iv fluids, amikacin or enro and ampicillin maropitant ( cerenia) sucralfate , vaccnation and ygene to prevent
