24
Q

T/F: Atopic dermatitis is a type I hypersensitivity disorder where allergic dogs develop allergen-specific IgE antibodies against common environmental allergens.

A

True

25
Q

T/F: TH2 lymphocytes play a role in the pathogenesis of atopic dermatitis because they secrete IL-4 which signals B-cells to switch to immunoglobulin class to IgE.

A

True

TH2 –> IL-4 –> IgE

26
Q

T/F: Papules, pustules and epidermal collarettes are lesions frequently seen in dogs with atopic dermatitis and most of the time they represent the patient’s immune response to environmental allergens.

A

False

Initial pruritus is UNassociated with lesions

27
Q

T/F: Atopic dermatitis can be easily differentiated from food allergy based on clinical signs.

A

False

28
Q

T/F: Otitis externa can be the first and sometimes the only clinical sign of atopic dermatitis.

A

True

Recurrent otitis externa

29
Q

T/F: Oral glucocorticoids can be safely used to manage atopic dermatitis on a long-term basis if used daily at a low dosage.

A

False

Only alternate day therapy is safe

30
Q

T/F: Atopic dermatitis can be ruled out if a dog or cat have negative skin and/or serum allergy test results.

A

False

Only used for choosing immunotherapy

31
Q

T/F: Cyclosporine has been shown to be as effective as glucocorticoids to manage atopic dermatitis.

A

True

But it is more expensive

32
Q

T/F: Food allergy is typically a seasonal pruritic dermatitis that affects dogs & cats.

A

False

It occurs whenever the triggering food is eaten

33
Q

T/F: Serum tests to measure food IgE specific antibodies are accurate to diagnose canine or feline food allergy.

A

False

Only food trials are reliable

34
Q

T/F: A positive intradermal test for flea antigens is required for the diagnosis of flea bite allergy.

A

False

Dx is from history and clinical signs

35
Q

T/F: No food challenge is needed if a dog’s clinical signs improve by at least 50% during a food trail.

A

False

Challenge trial is alway required

36
Q

T/F: Non-inflammatory, self-induced alopecia can be a clinical presentation of food allergy or atopic dermatitis in cats.

A

True

They are itchy!

37
Q

T/F: Allergen specific immunotherapy works well for flea bite allergy.

A

False

Totally unsuccessful so far

38
Q

T/F: Adult fleas are NOT obligate parasites and can live off the host for a long time.

A

False

Can only survive 3-4 days

39
Q

T/F: Intermittent exposure to fleas, exposure late in life and atopic dermatitis are predisposing factors for flea bite allergy.

A

True

40
Q

T/F: Canine follicular demodicosis is a contagious disease and all animals in the household need to be treated.

A

False

Follicular mite = demodex canis is a normal skin inhibitant

41
Q

T/F: Juvenile- onset generalized demodicosis can spontaneously resolve in about 90% of cases and benign neglect is an option.

A

False

Only in 30-50% of cases. Don’t wait to treat

42
Q

T/F: A dog treated for generalized demodicosis that received treatment for 30 days past two negative skin scrapings can be declared cured.

A

False

Only in remission! Dog needs negative skin scrapings every 4 months for 1 year

43
Q

T/F: Adult-onset canine demodicosis is NOT considered a hereditary disorder in contrast with the juvenile-onset generalized demodicosis.

A

True

44
Q

T/F: Adult-onset generalized demodicosis has a very good prognosis and often it spontaneously resolves.

A

False

Commonly due to an underlying immunosuppressive disease

45
Q

What disorder can be ruled out if no mites are found on multiple skin scrapings?

A 
Follicular demodicosis
(Demodex = follicle mite)
46
Q

Q

T/F: Feline follicular demodicosis is usually seen in middle age to older cats that have an underlying disease.

A

True

51
Q

False!

53

A

False

Cannot use skin scrapings to determine duration of therapy! Treat for the recommended duration based on drug selected

55
Q

Dermatophyte test media (DTM) is great because only dermatophytes can turn the media red; therefore, it is very easy to interpret test results.

A

False

Need to identify colonies with an early color change

56

Griseofulvin is a safe and very efficacious treatment option for feline dermatophytosis.
