Canine and Feline Flashcards
(1011 cards)
What is the diagnosis if a skin lesion fluoresces under woods lamp but has a negative skin scrape
Ringworm - microsporum canis fungus ( only 50% of positive cases will fluoresc)
What is the best treatment for ringworm
Combo topical and oral therapy - antifungal shampoo with miconazole and oral like itraconarole or fluconazole
Will doxycycline treat ringworm
No dummy - doxycycline is an antibiotic and will not treat fungal infections
What are you suspicious of if you see an elevated heart Off the sternal wall on thoracic rads
Pneumothorax
What would a globoid heart be suggestive of on rads
Pericardial effusion
A delicit in what nerve would lead to a loss of motor function in the muscles of mastication
Cranial nerve 5
Deficits in what canid nerves could lead to strabismus
Cranial nerve 3 (oculomotor nerve), 4 (trochlear) or 6 (abducent nerve)
What can cause nystagmus
CNS disease or cranial nerve 8 deficits
What would you expect to see with deficits in cranial nerve 7 (facial nerve)
Exposure keratitis because facial nerve 7 controls lacrimation
Define exposure keratitis
Damage to the. Correa due to dryness
How do cats and dogs became infected with cutebra larvae (as they do not bite or feed)
EnvironmentaL exposure - larvae attach through fur and enter body during grooming or through an open wound
Where do cutebrea larvae usually localize to and when do you see infections mostly
Localize to the skin of the neck, head and trunk (but don’t usually go through the skin), sec mostly in late summer and fall
Hypochloremia in a yang anorexia animal is most suggestive of
Upper GI obstruction
What is the screening test for hyperthyroidism in cats
Total T4
What would help you differentiate between metastatic neoplasia and systemic fungal disease on radiographs
With systemic fungal disease there would be evidence of hilar lymphadenopathy
Which poisonous plant can lead to acute death
Milkweed
Atrial fibrillation sounds like
Shoes in a dryer
Anti pruitic meds are considered -, trey provide relief but don’t
Bandaids - provide relief but don’t cure the underlying cause of the pruitis
What are the 4 main antipruitic drugs used in dermatology
Apoquel (octlacitinib) , cytopoint ( lokivetmab), cyclosporine (atopic a) and prednisone (steroid)
_ Is the key mediator of pruritis
IL 31 - a cytokine that causes release of proinflammatory cytokines by activating the jak/stat pathway
Give a brief brief summary of the jak/stat pathway
IL 31 activates a jak receptor I which activates stat which travels to the cell nucleus to cause release of proinfommatory cytokines and itch
What is the main difference between apoquel and cytopoint in terms of their MOA
Both activate the jak/stat path that cause pruritis but cytopoint acts higher in the path than apoquel; apoquel is a jak inhibitor (blocks itch by not letting jak bind), cytopoint binds IL 3I so it can’t activate the jak/stat path
How does prednisone act as an antiprurituc
Inhibit inflammation and up regulates anti inflammatory mediators
Depending on the dose I prednisone can be - or -
Anti inflammatory or immunosuppressive
