Summary
Visual analog scales (VAS) reliably quantify nasal obstruction in allergic rhinitis (AR) patients. This offers a practical alternative to rhinomanometry when it is unavailable.
Area of Science:
- Otolaryngology
- Allergy and Immunology
Background:
- Nasal airflow resistance is often impaired in allergic rhinitis (AR).
- Rhinomanometry is the standard but is not widely available.
Purpose of the Study:
- To assess the utility of visual analog scales (VAS) as a substitute for rhinomanometry in measuring nasal obstruction in persistent AR patients.
Main Methods:
- A prospective study was conducted with 50 allergic rhinitis patients at an ENT clinic.
- Patients completed VAS for nasal obstruction and other AR symptoms, alongside rhinomanometry.
Main Results:
- A very strong correlation (Spearman r = 0.879, P < 0.001) was found between VAS for nasal obstruction and rhinomanometry measurements.
- A significant correlation was also observed between VAS for rhinorrhea and nasal airflow resistance (Spearman r = 0.313, P = 0.027).
Conclusions:
- Visual analog scales (VAS) provide a clinically relevant and reliable method for quantifying nasal obstruction in AR.
- VAS can be effectively used in place of rhinomanometry when the latter is not accessible.

Drugs Used in Upper Respiratory Disorders: Overview
Upper respiratory tract disorders, including viral infections and allergic rhinitis, cause significant discomfort and disrupt daily life. Managing these conditions involves a variety of drugs, such as antihistamines, intranasal steroids, decongestants, antitussives, expectorants, and mucolytics. Specific examples of drugs in each category are provided.
Antihistamines (e.g., Benadryl) block histamines from binding. Histamines are chemicals released during an allergic reaction in the body. As a...

Nose and Nasal Cavity
The nose is composed of an observable exterior segment (external nose) and an internal segment within the skull known as the nasal cavity (internal nose). The external nose, visible on the face, consists of a framework of bone and hyaline cartilage enveloped in skin and muscle and lined with a mucous membrane. This structure is supported by the frontal bone, nasal bones, and maxillary bone and is supplemented by a cartilaginous framework comprising the septal nasal cartilage, lateral nasal...
Epistaxis
Epistaxis, or nosebleeds, occurs when small, swollen blood vessels in the nasal mucous membrane rupture. Typically, the anterior septum is the primary site of occurrence.
Etiology
Possible causes of this condition include high blood pressure, trauma, low humidity, upper respiratory tract infections, allergies, foreign bodies, nasal inhalation of corticosteroids or illicit drugs, excessive use of decongestant nasal sprays, facial or nasal surgery, anatomic malformation, tumors, or systemic...

Asthma III: Clinical Manifestations
Asthma presents with a characteristic pattern of episodic respiratory symptoms that reflect underlying airway inflammation, bronchoconstriction, and mucus hypersecretion. Although severity varies among individuals, certain clinical manifestations are considered hallmarks of the disorder and often guide diagnosis and assessment.Respiratory SymptomsA persistent cough is one of the most common early features of asthma. It is frequently dry and tends to worsen at night or in the early morning,...
Respiratory Volumes
Respiratory volumes are crucial metrics, meticulously measured to quantify the air exchanged in and out of the lungs during various phases of the breathing cycle. These precise measurements are vital for assessing lung function, diagnosing respiratory conditions, and monitoring overall respiratory health. Each parameter provides specific insights into the mechanics of breathing and the functional capacity of the lungs.

Asthma-III: Symptoms and Complications
Asthma, a common chronic respiratory condition, is classified considering the frequency and severity of symptoms alongside lung function impairment. Understanding this classification is essential for appropriate treatment and management. Here's a detailed look at the classification of asthma and its clinical features and complications:
