[Oto-respiratory reflex in patients with pollinosis]
1Instytutu Gruźlicy i Chorób Płuc, Warszawie.
Summary
The oto-respiratory reflex, a cough triggered by ear canal irritation, may predict bronchial symptoms in grass pollen-sensitive individuals. This reflex shows 50% sensitivity and 92% specificity for predicting pollinosis-related respiratory issues.
Area of Science:
- Otolaryngology
- Allergology
- Respiratory Medicine
Context:
- Grass pollen sensitivity affects numerous individuals, often leading to seasonal allergic rhinitis and asthma.
- Asymptomatic patients during the non-pollen season were studied to identify early predictive markers.
- The link between ear canal stimulation and respiratory responses in allergic individuals is not fully understood.
Purpose:
- To investigate the potential of the oto-respiratory (or oto-cough) reflex as a predictive measure for bronchial symptoms in grass pollen-sensitive patients.
- To determine the sensitivity and specificity of the oto-cough reflex in identifying individuals at risk for pollinosis-related respiratory issues.
Summary:
- Fiberoptic otoscope examinations were conducted on 53 asymptomatic grass pollen-sensitive patients.
- Mechanical irritation of the external auditory canals induced a cough reflex in 11 patients (20.75%).
- The presence or absence of bronchial symptoms was analyzed, concluding that the oto-cough reflex can predict these symptoms with 50% sensitivity and 92% specificity.
Impact:
- Identifies a simple, non-invasive clinical sign (oto-cough reflex) for predicting respiratory complications in pollinosis.
- Suggests potential for early intervention in patients with grass pollen sensitivity and a positive oto-cough reflex.
- Highlights the interconnectedness of the auditory and respiratory systems in allergic diseases.

Assessment of Respiration
The respiratory system's basic structures and primary functions lay the foundation for nurses' comprehensive respiratory assessments. This assessment includes subjective and objective data to gauge the patient's respiratory health.
Subjective Assessment: Nurses interview the patient to gather information directly during the subjective assessment. It includes questions about the individual's medical history, medications, and symptoms, focusing on past respiratory conditions like asthma or COPD,...

Physiological Control of Respiration
Introduction
Breathing, a seemingly passive process, is regulated by the respiratory center in the brainstem. This center coordinates the involuntary control of respirations, which means it occurs without conscious effort, ensuring a smooth and uninterrupted pattern.
Regulation of Ventilation
The body maintains ventilation by monitoring levels of carbon dioxide (CO2), oxygen (O2), and hydrogen ion concentration (pH) in the arterial blood. Among these factors, the level of CO2 plays a crucial...

Respiratory Assessment: Purpose and Indications
Respiratory assessment is a cornerstone of nursing assessments, crucial for the early detection of patient deterioration. This evaluation transcends routine procedures, representing a critical skill nurses must master to ensure optimal patient care.
Objectives and Importance:
The primary goal of respiratory assessment is to evaluate patients at early risk of clinical deterioration. Since respiratory distress often precedes other signs of declining health, breathing patterns and sounds become a...

Physical Assessment of the Respiratory Tract II: Inspection
Physical assessment of the respiratory tract through inspection is a crucial step in understanding the patient's respiratory health. It provides insights into the functioning of the respiratory system, the musculoskeletal structure, and even the patient's nutritional status. This comprehensive approach involves observing several vital aspects: chest configuration, breathing patterns, respiratory rates, skin color, and use of accessory muscles.

Microbiota of the Respiratory Tract
The human respiratory tract, comprising the upper and lower segments, serves as a critical interface with the external environment. The upper respiratory tract (URT)—including the nostrils, sinuses, pharynx, and oropharynx—is heavily colonized by microbes, while the lower respiratory tract (LRT), composed of the larynx, trachea, bronchi, and lungs, was long thought to be sterile. However, recent molecular studies have revealed that the lungs are not devoid of microbes but act more like...
Asthma 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...
