Vaccination counseling with and without excipient skin testing in patients with suspected allergic reactions to mRNA COVID-19 vaccines and patients with atopy.

Background: Allergic reactions have been reported with mRNA vaccines for COVID-19 prevention. Patients perceived to be at higher risk for a reaction may be referred to an allergist, although evaluation strategies may differ between allergists.

Objective: Our aim was to determine outcomes of COVID-19 vaccinations in patients evaluated by an allergist using different approaches.

Clinical Characteristics of Patients with Chronic Rhinosinusitis without Nasal Polyps in an Academic Setting.

Background: Although patients with chronic rhinosinusitis without nasal polyps (CRSsNP) represent a majority of the chronic rhinosinusitis (CRS) population, they have not been completely characterized phenotypically.

Objective: To perform a comprehensive phenotypic characterization of subjects with CRSsNP, using CRS with nasal polyps (CRSwNP) as a comparator.

Methods: Patients with a history of CRS with positive sinus computed tomography (>18 years old) evaluated in the allergy/immunology or otolaryngology clinics of an academic center between 2002 and 2012 were identified via International Classification of Diseases, Ninth Revision codes.
