Upper Respiratory Drugs: Decongestants01:27

Upper Respiratory Drugs: Decongestants

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 various...

Upper Respiratory Drugs: Antitussives, Expectorants, and Mucolytics

Respiratory symptoms, such as congestion and cough, commonly accompany respiratory tract conditions. Various medications, such as antitussives, expectorants, and mucolytics, play crucial roles in providing relief.
Antitussives include codeine, dextromethorphan (Robitussin), and benzonatate (Tessalon). Codeine and dextromethorphan exert their effects centrally by suppressing the cough reflex center in the medulla.  Benzonatate operates peripherally within the respiratory tract by anesthetizing...
Chronic Pharyngitis01:23

Chronic Pharyngitis

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,...
Common Respiratory Disorders01:31

Common Respiratory Disorders

Respiratory disorders, a prevalent health concern globally, are generally divided into two primary categories: upper and lower respiratory tract disorders. The categorization is based on the area of the respiratory system they affect.
Upper respiratory disorders impact the airways above the vocal cords, encompassing areas like the nose, sinuses, and throat. Various conditions fall under this category, including the common cold and allergic rhinitis. These disorders can stem from several causes,...
Atypical Pneumonia01:14

Atypical Pneumonia

Atypical pneumonia, often caused by Mycoplasma pneumoniae, is a form of pulmonary infection that differs from the classical presentation of bacterial pneumonia in both its cause and clinical symptoms. Mycoplasma pneumoniae is a pleomorphic bacterium notable for its lack of a rigid cell wall. This structural characteristic imparts resistance to beta-lactam antibiotics and significantly influences the bacterium’s behavior within the human host.Other pathogens responsible for the disease include...
Drugs Used in Upper Respiratory Disorders: Overview01:16

Drugs Used in Upper Respiratory Disorders: Overview

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...

Summary
This summary is machine-generated.

A young adult successfully had a foreign body removed from their right main bronchus via rigid bronchoscopy. The object had been lodged for at least five days, with no recollection of aspiration.

Area of Science:

  • Pulmonology
  • Medical Case Reports
  • Bronchoscopy

Background:

  • Foreign body aspiration in adults is uncommon.
  • Patients may not recall the aspiration event.
  • Prolonged impaction can lead to complications.

Purpose of the Study:

  • To report a case of a young adult with a retained foreign body in the right main bronchus.
  • To highlight the diagnostic challenges when aspiration is not recalled.
  • To demonstrate the efficacy of rigid bronchoscopy for foreign body removal.

Main Methods:

  • A case of a young adult presenting with respiratory symptoms was investigated.
  • Diagnostic imaging was utilized to identify the foreign body.
  • Rigid bronchoscopy was performed for foreign body extraction.

Main Results:

  • A foreign body was confirmed in the right main bronchus.
  • The object had been present for at least 5 days.
  • Successful removal of the foreign body was achieved using rigid bronchoscopy.

Conclusions:

  • Rigid bronchoscopy is an effective treatment for bronchial foreign bodies.
  • Aspiration events should be considered even without patient recollection.
  • Prompt diagnosis and intervention are crucial for favorable outcomes.
