Chronic Pharyngitis01:23

Chronic Pharyngitis

14.2K
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,...

Epistaxis01:30

Epistaxis

698
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...

Anatomy of Respiratory System I: Upper Respiratory Tract

6.2K
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....

Chronic Obstructive Pulmonary Disease-I: Introduction01:20

Chronic Obstructive Pulmonary Disease-I: Introduction

4.1K
Chronic Obstructive Pulmonary Disease (COPD) is a long-lasting respiratory condition requiring continuous attention and care. It is a progressive lung disease that leads to breathing challenges due to airflow obstruction. It manifests as persistent respiratory symptoms and restricted airflow resulting from abnormalities in the airways and alveoli, usually due to long-term exposure to harmful particles or gases. COPD mainly consists of two primary conditions: emphysema and chronic bronchitis.

Chronic Obstructive Pulmonary Disease01:24

Chronic Obstructive Pulmonary Disease

3.0K
COPD is defined as a heterogeneous lung condition marked by persistent respiratory symptoms such as dyspnea, cough, and sputum production, caused by abnormalities in the airways that cause airflow obstruction.
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...

Drugs Used in Upper Respiratory Disorders: Overview01:16

Drugs Used in Upper Respiratory Disorders: Overview

957
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...

Area of Science:

  • Otolaryngology
  • Immunology
  • Pathology

Background:

  • Chronic rhinosinusitis without nasal polyps (CRSsNP) is more common than CRSwNP.
  • Predisposing factors include airway diseases, immunodeficiencies, autoimmune disorders, infections, smoking, biofilms, and innate immune defects.
  • CRSsNP exhibits histologic changes like basement membrane thickening and goblet cell hyperplasia, with neutrophils, TGF-β, and CXCL-8 implicated in remodeling.

Purpose of the Study:

  • To review the predisposing factors and pathogenesis of CRSsNP.
  • To highlight the histologic and cellular characteristics of CRSsNP.
  • To identify areas requiring further research for improved understanding and treatment.

Main Methods:

  • Literature review of CRSsNP pathogenesis, predisposing conditions, and histologic findings.
  • Analysis of the roles of specific immune cells, chemokines, and environmental factors.
  • Discussion of current understanding and identification of knowledge gaps.

Main Results:

  • CRSsNP is associated with a wide range of systemic and environmental factors.
  • Histologic hallmarks include fibrosis and goblet cell hyperplasia.
  • The roles of neutrophils, TGF-β, and CXCL-8 in CRSsNP pathogenesis are recognized, though endotype data (neutrophilic vs. eosinophilic) remain conflicting.

Conclusions:

  • Understanding the diverse factors contributing to CRSsNP is crucial.
  • Further investigation into CRSsNP endotypes and mechanisms is necessary.
  • Additional research is required to develop evidence-based treatment strategies.
