Abstract:
Previous studies overestimated the incidence of pregnancy-associated rhinitis because it is a poorly defined clinical condition. The objective of this study was to assess the incidence of this unique type of rhinitis using up-to-date strict criteria. This prospective study included 109 primigravida parturients who were interviewed using a structured questionnaire and underwent detailed rhinoscopy. Pregnancy-associated rhinitis was defined as nasal obstruction symptom and rhinorrhea appearing during pregnancy, lasting for at least 2 months, and disappearing postpartum. The incidence of rhinitis associated with pregnancy at the time of delivery was 9%. No correlation was found between symptoms and signs. Pregnancy-associated rhinitis is an infrequent clinical entity. It may be related to hormonal changes and possibly altered sensation of nasal airflow.

Upper Respiratory Drugs: Antitussives, Expectorants, and Mucolytics
Antitussives include codeine, dextromethorphan (Robitussin), and benzonatate (Tessalon). Codeine and dextromethorphan exert their effects centrally by suppressing the cough reflex center in the medulla. Benzonatate operates peripherally within the respiratory tract by anesthetizing...

Asthma: Pathogenesis and Management
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
