This prospective, virtually administered trial conducted throughout the United States aims to evaluate a standardized protocol including the serial dilution of topical decongestants with concurrent topical steroids (triamcinolone), for elimination of dependence on topical decongestants.
This research is studying the long term use of a nasal airway device (self-supporting nasopharyngeal airway; "ssNPA") in children with hypotonic upper airway obstruction to learn about its effectiveness and tolerability as a treatment for obstructive sleep apnea.
The purpose of this pilot study is to evaluate allergen-induced nasal airway inflammation following nasal application of Dermatophagoides farinae (Der f), or house dust mite, extract in e-cigarette users, cigarette smokers, and non-smokers.
This clinical investigation is designed to assess the F\&P Toffee Nasal and Toffee Nasal Pillows masks in home for use during PAP therapy delivery. The objectives of the investigation are to assess therapeutic efficacy, safety and comfort.
This aim will examine the acute and subacute exposures to electronic cigarette (EC) vapor generated from e-liquids without nicotine (NFEC) on life-time non smokers subjects by measuring changes in nasal ion transport and TGF-β levels. Nasal ion transport will be assessed by nasal potential difference (NPD). Tumor growth factor (TGF)-β levels (mRNA and protein by ELISA) will be assessed on nasal cells and lavages.
