Summary
Approximately 30% of patients with nasal disease and asthma reported that nasal symptoms worsen their asthma. Treating nasal conditions can improve asthma control, particularly for those with poorly controlled asthma.
Area of Science:
- Allergy and Immunology
- Respiratory Medicine
- Epidemiology
Context:
- The link between allergic rhinitis and bronchial asthma is established, but epidemiological data on nasal diseases and asthma, especially in Japan, is limited.
- Understanding this relationship is crucial for comprehensive allergy management.
Purpose:
- To investigate the association between nasal symptoms and asthma exacerbations in patients with both conditions.
- To identify patient subgroups where nasal symptom changes significantly impact asthma control.
- To evaluate the effect of nasal treatment on asthma symptoms.
Summary:
- A questionnaire study of 126 patients revealed that 30% reported nasal disease exacerbations worsening their asthma.
- Nasal treatment improved asthma in 22% of patients.
- The impact of nasal symptoms on asthma was more pronounced in patients with poor asthma control and those with sinusitis.
Impact:
- Nasal treatment is a potentially important component of asthma management, especially for patients experiencing symptomatically linked nasal and respiratory issues.
- Highlights the significance of integrated allergy care for effectively managing both nasal diseases and asthma.
- Provides epidemiological insights into the nasal-asthma connection in a Japanese population.

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:

01:13Asthma 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,...
01:28Asthma 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...
01:29Asthma-I: Introduction
Asthma is a chronic respiratory ailment that requires careful management due to its varying symptoms and influencing factors. It is characterized by airway inflammation, bronchial hyperresponsiveness, and reversible airflow obstruction, leading to symptoms like wheezing, shortness of breath, chest tightness, and coughing. The symptom frequency and intensity may vary considerably over time. It is also linked to immune system responses to allergens and irritants, highlighting the complex...
