Questions

1. Which of these clinical presentations is a common presentation for cutaneous food adverse reactions in cats: *

Self-inflicted symmetrical alopecia

Miliary dermatitis

Head/neck pruritus/excoriations

Plasma cell pododermatitis

2. What is the most likely diagnosis of an outdoor cat with an acute and pruritic nasal dermatitis (papules, crusts, erosions) without other lesions on the body? *

Mosquito bite hypersensitivity

Cutaneous food adverse reaction

Feline atopic syndrome

Dermatophytosis

3. Why is the term “feline atopic syndrome” used rather than “feline atopic dermatitis”? *

Because cats do not produce IgE, an antibody that plays a major role in atopic dermatitis

Because cats do not present any skin barrier dysfunction despite numerous studies on the subject, but which is seen in atopic dermatitis

Because the etiopathogenesis has been well defined, and the inflammatory skin reaction reported in cats allergic to environmental substances is different from that observed in atopic dermatitis

Because the lack of scientific data showing the etiopathogenesis of allergy associated with environmental substances in cats does not support a clear conclusion supporting atopic dermatitis, as is defined in dogs

4. Regarding the pruritic cat: *

We should have a stepwise approach to eliminate dermatosis, one type at a time

We should perform an allergy test right away to determine the source of the allergy in allergic cats

We should always prescribe an antipruritic drug regardless of the underlying cause

We should recommend an elimination diet trial, and if there is no response, prescribe antiparasitic and/or antimicrobial treatments as a second step

5. True or false. Feline atopic syndrome is a diagnosis of exclusion. *

True

False

6. What type of hypersensitivity is mainly targeted by commercial diets containing hydrolyzed proteins? *

Type 1 hypersensitivity

Type 2 hypersensitivity

Type 3 hypersensitivity

Type 4 hypersensitivity

7. A cat suffering from a cutaneous food adverse reaction is fed a commercial diet containing a novel source of protein. Which of the following statements is FALSE? *

The choice of this diet is based on the cat's dietary history

Diets based on novel proteins could control 70–80% of cases of cutaneous food adverse reaction, at least in dogs

This type of diet does not allow for future sensitization to the novel source of protein

The commercial diet (vs. a homemade diet) is chosen by taking into account the lifestyle of the owners

8. True or false. Allergen immunotherapy is the only therapy with the potential to cure feline atopic syndrome. *

True

False

9. Which of these treatments is approved for the control of allergic dermatitis in cats? *

Maropitant

Oclacitinib

Chlorpheniramine

Cyclosporin

10. The major allergen produced by cats and that causes allergic reactions in people is: *

Fel d1

Fel d4

Fel d8

Fel d10
