Chronic Pharyngitis01:23

Chronic Pharyngitis

10.9K
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: Overview01:16

Drugs Used in Upper Respiratory Disorders: Overview

622
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

4.7K
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....

Tonsillitis I: Introduction

1.8K
Tonsillitis is inflammation of the tonsils, which are two lymphoid tissue masses at the back of the throat. This condition can cause discomfort and irritation in the throat.
Etiology
Three primary contributing factors have been identified.

Upper Respiratory Drugs: Decongestants01:27

Upper Respiratory Drugs: Decongestants

817
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...

Area of Science:

  • Otolaryngology
  • Inflammatory Diseases

Background:

  • Acute rhinosinusitis (ARS) is usually viral and self-limiting; bacterial ARS is uncommon.
  • Chronic rhinosinusitis (CRS) is a persistent inflammatory condition with varied histopathology.
  • Both ARS and CRS significantly affect quality of life and healthcare costs.

Purpose of the Study:

  • To review current understanding and management of ARS and CRS.
  • To highlight recent advancements in treating severe CRS.
  • To identify future research directions for rhinosinusitis.

Main Methods:

  • Literature review of recent advancements in ARS and CRS.
  • Analysis of diagnostic and therapeutic strategies based on severity and endotype.
  • Synthesis of findings regarding quality of life and cost impacts.

Main Results:

  • Viral ARS is common, bacterial ARS is rare and often overdiagnosed.
  • CRS management strategies are evolving, with improved outcomes for severe cases.
  • Personalized treatment approaches are emerging for CRS.

Conclusions:

  • Further research into biomarkers is crucial for personalized rhinosinusitis treatment.
  • Advancements offer improved outcomes for patients with severe chronic rhinosinusitis.
  • Optimizing treatment based on endotype and severity is key for future management.
