Epistaxis01:30

Epistaxis

151
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...

Suctioning the Nasopharyngeal Airway01:29

Suctioning the Nasopharyngeal Airway

392
Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia.

Chronic Pharyngitis01:23

Chronic Pharyngitis

1.9K
Chronic pharyngitis refers to persistent inflammation of the pharyngial mucosa.
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...

Drugs Used in Upper Respiratory Disorders: Overview

234
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...

Anatomy of Respiratory System I: Upper Respiratory Tract01:29

Anatomy of Respiratory System I: Upper Respiratory Tract

1.4K
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....

Upper Respiratory Drugs: Decongestants01:27

Upper Respiratory Drugs: Decongestants

209
Decongestants are a class of medications used primarily to alleviate nasal congestion, a common symptom resulting from allergies, colds, sinusitis, and other upper respiratory tract infections. These drugs work by activating α-adrenergic receptors, constricting small blood vessels in the nasal membranes. This action results in the opening of clogged nasal passages, thereby facilitating sinus drainage and relieving congestion.
Most decongestants are readily available over-the-counter in...

Summary
This summary is machine-generated.

Postnasal drip (PND) is a common symptom often linked to sinonasal issues or reflux. Current understanding of its exact cause and objective assessment remains limited, necessitating reliance on patient-reported outcomes.

Area of Science:

  • Otolaryngology
  • Rhinology
  • Gastroenterology

Background:

  • Postnasal drip (PND) is a frequent complaint in patients with sinonasal disease.
  • PND can occur independently or as a manifestation of laryngopharyngeal reflux (LPR).
  • The precise pathophysiology of PND, potentially involving mucus clearance dysfunction, is not definitively established.

Purpose of the Study:

  • To review the current understanding of postnasal drip.
  • To discuss evidence-based treatment strategies for PND.
  • To highlight the diagnostic challenges and reliance on subjective measures.

Main Methods:

  • Literature review of existing studies on PND.
  • Analysis of current diagnostic approaches and their limitations.
  • Evaluation of treatment efficacy based on available evidence.

Main Results:

  • PND is a common symptom with unclear pathophysiology.
  • Objective diagnostic tools for PND are lacking.
  • Patient-reported outcome instruments, like the Sino-Nasal Outcome Test, are crucial for assessment.

Conclusions:

  • Further research is needed to elucidate the exact pathophysiology of PND.
  • Effective management relies on addressing underlying causes and symptom relief.
  • Standardized objective assessment tools would improve PND diagnosis and management.
