Summary
Weather significantly impacts sino-nasal symptoms. Dry, polar, and transitional weather days increase symptom severity, suggesting climate
Area of Science:
- Rhinology and Environmental Health
- Clinical Allergy and Immunology
Background:
- Anecdotal evidence suggests weather influences sino-nasal symptoms.
- Objective assessment of weather-symptom relationships in rhinology is needed.
- The Sino-Nasal Outcome Test (SNOT-22) is a validated measure of symptom severity.
Purpose of the Study:
- To investigate the association between daily weather types and sino-nasal symptom severity.
- To quantify the impact of specific weather conditions on patient-reported outcomes.
Main Methods:
- Retrospective analysis of 955 SNOT-22 surveys from 481 patients (2010-2020).
- Spatial Synoptic Classification (SSC) used to categorize daily weather types.
- Logistic regression analyzed the odds of high SNOT-22 scores (≥50) based on SSC weather types (lagged 0-3 days).
Main Results:
- Dry, polar (DP) and transitional (TR) weather days showed 2.0 times higher odds of severe symptoms compared to other weather types.
- DP days had 4.0 times higher odds of severe symptoms compared to dry moderate days.
- Weather on the day of the clinic visit and up to three days prior influenced symptom severity.
Conclusions:
- Specific weather patterns, particularly DP and TR, are significantly associated with increased sino-nasal symptom severity.
- Environmental factors, such as climate, play a measurable role in managing and assessing rhinology conditions.
- Clinicians should consider weather's impact when evaluating treatment outcomes for sino-nasal diseases.

01:24Nose 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...
01:28Physical Assessment of the Respiratory Tract I: Health History
Physical assessment of the respiratory tract is critical to patient care. It allows healthcare professionals to identify and manage various respiratory conditions. The process involves a combination of subjective and objective data collection.
Subjective Data
Subjective data provides vital information about the patient's health history and symptoms. This data is typically collected through interviews in which patients describe their experiences, symptoms, and concerns.

01:24Asthma-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:

01:29Anatomy of Respiratory System I: Upper Respiratory Tract
The upper respiratory tract plays a vital role in the respiratory system, comprising several structures that facilitate air intake and prepare air for the lungs. It also serves as the first line of defense against pathogens and particles. This tract includes the nose and nasal cavity, the oral cavity, the paranasal sinuses, and the pharynx, each with specific functions and features.
Nose and nasal cavity
The nose and nasal cavity represent the main external openings of the respiratory tract.

01:13Asthma 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,...
01:25Chronic Obstructive Pulmonary Disease-III: Symptoms and Complications.
Understanding the variety of primary symptoms and systemic complications that characterize chronic obstructive pulmonary disease (COPD) is crucial for healthcare professionals.
Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.
