Summary
Allergic rhinitis significantly impairs olfactory function in patients. This allergy-related smell loss is more pronounced in those with pollen allergies compared to mite allergies.
Area of Science:
- Otorhinolaryngology
- Allergology
- Neuroscience
Context:
- Allergies, particularly allergic rhinitis, have significantly increased in Europe over the past 80 years.
- Allergic rhinitis is the predominant manifestation of allergies, with prevalence rising substantially.
- The olfactory system's function is increasingly recognized as a crucial aspect of overall health.
Purpose:
- To investigate and demonstrate the impact of allergic rhinitis, specifically due to pollen and mites, on the olfactory system.
- To quantify olfactory impairment in individuals with allergic rhinitis compared to healthy controls.
- To differentiate the effects of pollen-induced versus mite-induced allergic rhinitis on smell perception.
Summary:
- Individuals with allergic rhinitis exhibit a significant impairment in olfactory function, affecting both odor detection and identification.
- A trend suggests greater olfactory dysfunction in patients with pollen allergy compared to those with mite allergy.
- The study utilized the Barcelona Smell Test (BAST-24) to assess olfactory abilities in 76 allergic rhinitis patients and 120 healthy volunteers.
Impact:
- Highlights the need to consider olfactory status in the comprehensive assessment and management of allergic rhinitis patients.
- Provides evidence for distinct olfactory deficits based on allergen type (pollen vs. mites).
- Contributes to a better understanding of the link between allergic inflammation and sensory system dysfunction.

Overview
01:28Asthma I: Introduction
Asthma is a chronic inflammatory disorder of the airways characterized by variable airflow obstruction and heightened bronchial responsiveness to a wide range of triggers. The underlying inflammation leads to airway swelling, mucus hypersecretion, and smooth muscle constriction, all of which narrow the airway lumen and impede airflow. Clinically, asthma presents with recurrent episodes of wheezing, shortness of breath, chest tightness, and coughing, symptoms that typically vary in intensity and...
01:26Asthma-II: Pathophysiology and Classification
Asthma is a prevalent chronic respiratory condition marked by inflammation and hyperresponsiveness of the airways. Its pathophysiology involves complex interactions among inflammatory pathways, immune responses, and neural mechanisms.
Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
Critical processes in asthma pathophysiology include:

01:03Olfactory Receptors: Location and Structure
The process of olfaction, also known as the sense of smell, is a sophisticated chemical response system. The specialized sensory neurons that facilitate this process, known as olfactory receptor neurons, are situated in an upper segment of the nasal cavity, known as the olfactory epithelium. Olfactory sensory neurons are bipolar, with their dendrites extending from the epithelium's apex into the mucus that lines the nasal cavity. Airborne molecules, when inhaled, traverse the olfactory...
01:30Allergic Reactions: Anaphylaxis
Anaphylaxis is a severe, life-threatening hypersensitivity reaction mediated by Immunoglobulin E (IgE) antibodies. When IgE binds to allergens, it triggers the release of mediators– histamine, leukotrienes, and prostaglandins from mast cells and basophils. These mediators cause vasodilation, edema, and inflammation, leading to various symptoms.The primary allergens causing anaphylaxis include food items (e.g., peanuts, shellfish), drugs (e.g., penicillin, asparaginase, corticotropin, heparin),...
01:20Asthma: Pathogenesis and Management
Asthma is a chronic pulmonary condition involving inflammation of the airways, hyper-reactivity, and reversible obstruction of the airways. This condition can significantly impact a person's quality of life, making breathing difficult and leading to distressing symptoms.
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.
