Insights

Persistent atelectasis in children warrants investigation. This case highlights follicular bronchiolitis as a rare cause, successfully treated with corticosteroids after surgical intervention.

Area of Science:

  • Pediatric Pulmonology
  • Rare Respiratory Diseases
  • Histopathology

Background:

  • Persistent atelectasis in children necessitates identifying underlying causes.
  • Follicular bronchiolitis is a rare pulmonary condition characterized by lymphoid follicles.
  • Few pediatric cases of follicular bronchiolitis have been reported.

Purpose of the Study:

  • To describe a pediatric case of persistent left upper lobe atelectasis.
  • To identify follicular bronchiolitis as the cause of refractory respiratory symptoms.
  • To discuss the management and outcome of this rare condition in a child.

Main Methods:

  • Case report of a child with persistent atelectasis and respiratory symptoms.
  • Surgical intervention with partial lobectomy.
  • Histopathological examination of resected lung tissue.
  • Clinical assessment and treatment response evaluation.

Main Results:

  • Histopathology confirmed follicular bronchiolitis.
  • The patient experienced initial improvement with inhaled corticosteroids, followed by relapse.
  • Oral corticosteroid therapy led to a favorable clinical response.
  • Surgical lobectomy was performed due to refractory symptoms.

Conclusions:

  • Follicular bronchiolitis can present as persistent atelectasis and respiratory issues in children.
  • Corticosteroid therapy, including oral forms, can be effective.
  • Early diagnosis and appropriate treatment are crucial for favorable outcomes in rare pediatric lung diseases.

Pulmonary Cycle: Exhalation01:17

Pulmonary Cycle: Exhalation

In terms of human respiration, the act of expelling air, known as exhalation (or expiration), operates on the principle of pressure gradients. During expiration, the pressure within the lungs exceeds that of the surrounding atmosphere. Under normal conditions, quiet breathing involves passive exhalation and is free of muscular contractions. This is because the exhalation process is driven by the natural elastic recoil of the lungs and chest wall, both of which have an inherent tendency to...

Breathing01:05

Breathing

The process of breathing, inhaling and exhaling, involves the coordinated movement of the chest wall, the lungs, and the muscles that move them. Two muscle groups with important roles in breathing are the diaphragm, located directly below the lungs, and the intercostal muscles, which lie between the ribs. When the diaphragm contracts, it moves downward, increasing the volume of the thoracic cavity and creating more room for the lungs to expand. When the intercostal muscles contract, the ribs...

The Bronchial Tree

The human bronchi and bronchial tree play a crucial role in the respiratory system, facilitating the exchange of oxygen and carbon dioxide. Let's delve into the intricate structure and functions of these respiratory components.
The trachea, commonly known as the windpipe, is a tube that connects the larynx (voice box) to the bronchi. At a point called the carina, it bifurcates into two primary bronchi. The right primary bronchus is wider, shorter, and more vertical than the left primary...

Chronic Obstructive Pulmonary Disease

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...

Chronic Obstructive Pulmonary Disease-I: Introduction01:20

Chronic Obstructive Pulmonary Disease-I: Introduction

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.
