Allergic rhinitis is a symptomatic disorder of the nose secondary to IgE-mediated inflammation of the nasal membranes induced after exposure to allergens.
Major symptoms include nasal itching, watery rhinorrhea, nasal obstruction/congestion, sneezing and postnasal drainage.
Other symptoms include headache, conjunctival symptoms, eye pruritus, impaired smell and morning cough.
Symptoms can reverse spontaneous w/ or w/o treatment.
Getting vaccinated against influenza can improve survival of patients with heart failure (HF), with earlier and more frequent vaccination being associated with a greater protection against deaths from cardiovascular (CV) events or any cause, a large Danish nationwide cohort study shows.
