Q

Once an allergen binds to a IgE on a mast cells what happens?

A

histamine release occurs and bronchoconstriction follows and cellular cytokines are released in the early phase creating a drop in FEV1

Q

(blank) percent of patients have persistent rhinitis with 2/3 moderate to severe form

A

73%

30
Q

Are children likely to have seasonal allergies

A

no more likely to have year round symptoms due to encountering different aeroallergens throughout the year

31
Q

Lowest asthma symptoms was (blank)
Prevalence of wheeze was 32% in summer and 56% in fall (blank)
AR associated with increase risk of uncontrolled asthma during the (blank)
Presence of eczema was associated with higher risk of uncontrolled asthma during (blank)

Why is the wheeze the worst in fall?

A

summer
fall
spring
autumn

because of start of allergy season and school seaseon

A

3 and 4 your olds

34
Q

(blank) tests to outdoor allergens at baseline was the single most important predictive factor for incidence and persistence past puberty for allergic rhinitis and asthma. ie. this well tell you what children will remain asthmatics as adults

A

Positive skin tests

35
Q

What is the most likely way to get asthma and AR?

A

2/3 get AR first then asthma

36
Q 
Developmentally the (blank) occur together.  Therefore they share pathophysiologic pathways in common.
For subjects with AR and asthma:  the 49% taking nasal glucocorticosteriods had (blank) ER visits and hospitalizations
A

nose/lung

less

37
Q

Allergic rhinitis patients treated with (blank) have improvement in both rhinitis symptoms (expected) and bronchial reactivity/asthma symptom scores

A

nasal steroids

38
Q

(blank) is major allergen in rural and inner city and is linked to asthma severity.

A

Cockroach

39
Q

12% of children with asthma allergic to (blank)…this allergy linked to increased asthma severity in the inner city.

A

mice

40
Q

In the east, when are the most allergies?

If you have no redness or itch with a skin rash, what does this indicate?

A

not an allergic reaction

45
Q

What is the first step in allergy treatment?

A

removal of allergen, start pharm therapy prior to season (cuz once mast cells are activated AR/asthma is hard to control)
