Nasal and Sinus Disorders Flashcards
(44 cards)
Blood test for Allergic Rhinitis
RAST replaced by Fluorescence Enzyme-Labeled Assay, Expensive
Peripheral blood tests for AR
CBC, IgE but not descriptive
1st Gen Intranasal Corticosteroids for AR
10-50% Bioavailability(more SE). Beclomethasone(4yoa), Budesoinide-(Rhinocort 6yoa), Flunisolide(6) Triamcinolone(2)
2nd Gen Intranasal Corticosteroids for AR
Fluticasone propionate (<2%bioav)(4yoa), mometasone(nasonex) (<0.1%bioav) (2), Ciclesonide (Omnaris)(<0.1%bioav)(6), Fluticasone furoate(Veramyst)(<1%)(2)
Antihistamines that cause sedating, anticholinergic(Dry mouth)
1st Gen, Diphenhydramine, Chlorpheniramine(6yoa), Hydroxyzine
Antihistamines that are a lower risk for systemic effects
2nd and 3rd gen, Loratidine(2yrs), Cetrizine(Sedating in 10% of pts)(6mo), Fexofenadine 3rd gen (2yrs), Desloratidine (Clarinex 3rd gen (6mo)
Azelastine(Astelin), Olopatadine(Patanse)
AR tx: Intranasal Antihistamines
Combo intranasal antihistamine
Only Dymista (azelastine/fluticasone) shows better results than inhaled steroid alone.
AR and oral steroids
won’t relieve symptoms acutely, use sparingly. but may be needed to treat r. medicamentosa, severe, AR, sinusitis with allergic component
Oral Decongestant (AR Tx section)
pseudophedrine (Sudafed)
Pseudophedrine MOA SE
alpha/beta agonist (Vasocon), arrhythmia, hypertension, palpitations, tachy, HA, nervousness, stimulation, anorexia, tremor, ect.
Intranasal Cromolyn MOA and notes
Keeps mast cells from releasing histamines, but inferior to nasal steroids and antihistamines
Leukotriene receptor antagonist(approved for over 6mo of age) and notes
Montelukast (singular) Helps most with congestion, also used in pt’s with asthma, safe, but some rare psych SE
Phenylephrine, oxymetazoline, xylometazoline, nephazoline(Afrin, Neo-Synephrine) (risks) (aid in tx of epistaxis)
Nasal Decongestant Sprays. (only to be used for a day or two, otherwise risk of rebound)
AR Tx “not to be used as monotherapy”
Nasal Decongestant Sprays like Phenylephrine, oxymetazoline, xylometazoline, nephazoline(Afrin, Neo-Synephrine)
First Dose in office to observe. Grastek, O, R. (Daily through season-start 12 weeks)
SL Immunotherapy for AR. Oralair Ragwitek, 12 weeks before season starts
SQ Immunotherapy for AR
Testing done first, tailored to allergy, effects last 7-12 years
Expensive as hell immunotherapy for AR
Omalizumab (Xolair), Anti-immunoglobin E antibody, approved for use in asthma, not FDA approved for AR,
What conditions are Nasal Polyps associated with
Chronic sinusitis, asthma, aspirin sensitivity
Nasal Polyps in young children
Think possible CF
Tx for Nasal Polyps
Intranasal Corticosteroids, treat underlying allergies, consider other AR tx’s, oral glucocorticoids in refractory cases, surgical tx often recur
Order of sinus developement
MESF. F-after age 2 and last to pneumatize
Definition of Acute Rhinosinusitis
Symptomatic inflammation of the nasal cavity and paranasal sinuses lasting less than 4 weeks
What are the common viruses that cause Acute Rhinosinusitis
Rhinovirus, Adenovirus, Influenza virus, Parainfluenza virus
