Summary
This study followed children with chronic tonsillitis after tonsillectomy. Post-surgery, Antistreptolysin O (ASO) titre levels significantly decreased over one year.
Area of Science:
- Pediatric Otolaryngology
- Immunology of Infectious Diseases
Background:
- Chronic tonsillitis affects numerous children globally.
- Elevated Antistreptolysin O (ASO) titres indicate persistent streptococcal infection or inflammation.
- Tonsillectomy is a common surgical intervention for chronic tonsillitis.
Purpose of the Study:
- To evaluate the impact of tonsillectomy on Antistreptolysin O (ASO) titres in children with chronic tonsillitis.
- To assess the long-term trend of ASO titre reduction following surgical intervention.
Main Methods:
- Screening of 136 children under 15 with chronic tonsillitis.
- Selection of 56 patients with ASO titres > 200 IU/ml for tonsillectomy.
- Serial ASO titre measurements at 1 month, 3 months, 6 months, and 1 year post-tonsillectomy.
Main Results:
- A significant reduction in ASO titres was observed after tonsillectomy.
- ASO titres decreased to 62% at 3 months, 78% at 6 months, and 88% at 1 year post-surgery.
- The study demonstrates a clear downward trend in ASO titres over the follow-up period.
Conclusions:
- Tonsillectomy is an effective treatment for reducing elevated ASO titres in children with chronic tonsillitis.
- Surgical intervention aids in resolving underlying streptococcal activity or inflammation.
- This supports tonsillectomy as a viable option for managing persistent tonsillitis with elevated ASO levels.

01:23Chronic 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,...

01:26Endoscopic Studies II: Thoracocentesis
Thoracentesis(Thoracocentesis), commonly known as pleural tap, is a medical procedure where a 22 gauge needle is inserted into the pleural space, the area between the lung and chest wall. This procedure is commonly performed to diagnose or treat various respiratory disorders.
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...
