Insights
Bronchofibroscopy effectively identifies causes of chronic cough in children. This procedure is valuable for diagnosing conditions like respiratory infections and foreign bodies, aiding in timely treatment.
Area of Science:
- Pediatric Pulmonology
- Diagnostic Bronchoscopy
- Respiratory Medicine
Context:
- Chronic cough in children often presents diagnostic challenges.
- Etiologic identification is crucial for effective management.
- Bronchofibroscopy offers a direct visualization method.
Purpose:
- To evaluate the diagnostic utility of bronchofibroscopy for chronic cough in pediatric patients.
- To determine the range of etiologies identified by bronchofibroscopy.
Summary:
- Bronchofibroscopy was performed on 118 children (3 months–13 years) with unexplained chronic cough.
- The procedure successfully identified the cause in 115 cases.
- Common causes included respiratory infections (39), foreign bodies (19), and asthma (17).
Impact:
- Bronchofibroscopy is a valuable tool for diagnosing the causes of chronic cough in children.
- It facilitates targeted therapeutic interventions.
- This supports improved patient outcomes in pediatric respiratory care.
Objective:
To study the value of bronchofibroscopy in the etiologic identification of chronic cough in children.
Methods:
Under local anesthesia of lidocaine, bronchofibroscopy was performed in 118 children with chronic cough of unknown origin (73 males and 45 females). Their ages ranged from 3 months to 13 years.
Results:
The cause of chronic cough was identified in 115 cases. The most common cause was respiratory infection (n=39),followed by bronchial foreign bodies (n=19), upper airway cough syndrome (n=17), bronchial asthma or cough variant asthma (n=17), bronchomalacia (n=7), bronchial congenital malformation (n=5), primary ciliary dyskinesia (n=3), gastro-esophageal reflux (n=3), bronchial tumor (n=2), bronchial tuberculosis (n=1), pulmonary fibrosis (n=1) and idiopathic pulmonary hemosiderosis (n=1).
Conclusions:
Bronchofibroscopy is useful in the etiologic identification of chronic cough in children.

Chronic Obstructive Pulmonary Disease
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...
