Pneumonia I: Introduction01:30

Pneumonia I: Introduction

201
Pneumonia is an acute respiratory infection that targets the lungs, specifically the alveoli. These tiny air sacs, essential for oxygen exchange, become engorged with pus and fluid, severely hindering breathing, decreasing oxygen absorption, and causing significant pain and discomfort during respiration.
Risk Factors
Various factors influence the likelihood of developing pneumonia. Age plays a crucial role, with infants, children under two, and individuals over 65 at increased risk due to their...

Chronic Obstructive Pulmonary Disease-II: Pathophysiology

2.7K
Chronic Obstructive Pulmonary Disease (COPD) pathophysiology is intricate and multifaceted, involving a complex interplay of physiological processes. Understanding these mechanisms is crucial for effectively managing and treating COPD. Here is an in-depth look at the critical elements in the pathophysiology of COPD:

Pneumothorax-II

117
Pneumothorax is a medical condition defined by the buildup of air in the pleural space between the lungs and the chest wall. This accumulation of air can lead to partial or complete lung collapse, resulting in a range of clinical manifestations. Understanding the clinical presentation and effective management strategies is crucial for healthcare professionals in providing timely and appropriate care to individuals with pneumothorax.

Endoscopic Studies I: Bronchoscopy and Thoracoscopy

162
Endoscopy is a non-surgical medical technique used to examine a person's internal organs and vessels. This lesson will focus on two types of endoscopic studies: bronchoscopy and thoracoscopy.
Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...

Chronic Obstructive Pulmonary Disease01:22

Chronic Obstructive Pulmonary Disease

1.1K
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...

Area of Science:

  • Pulmonology
  • Oncology

Background:

  • Endobronchial leiomyoma is an uncommon benign tumor originating from smooth muscle tissue within the airways.
  • Airway obstruction by tumors can lead to secondary complications like post-obstructive pneumonia.

Purpose of the Study:

  • To report a case of endobronchial leiomyoma presenting as persistent pneumonia.
  • To highlight the diagnostic considerations for rare airway tumors and the efficacy of minimally invasive treatment.

Main Methods:

  • Case report of a 30-year-old female with persistent fever and cough.
  • Diagnostic workup including imaging and bronchoscopy.
  • Endobronchial cryo-resection for tumor removal.

Main Results:

  • Diagnosis of endobronchial leiomyoma confirmed.
  • Successful removal of the tumor via endobronchial cryo-resection.
  • Complete resolution of post-obstructive pneumonia and associated symptoms.

Conclusions:

  • Endobronchial leiomyoma, though rare, should be considered in cases of non-resolving pneumonia.
  • Minimally invasive endobronchial cryo-resection is an effective treatment option for endobronchial leiomyoma.
  • Prompt diagnosis and intervention are crucial for managing complications of airway tumors.
