Insights

Biofilms were found on tonsils and adenoids in most children undergoing surgery. Their presence was significantly higher in infected tissues, suggesting a link between biofilms and chronic inflammation.

Area of Science:

  • Microbiology
  • Otolaryngology
  • Pediatric Medicine

Background:

  • Biofilms are microbial communities that can cause persistent infections.
  • Tonsils and adenoids are common sites for recurrent infections and inflammation in children.
  • Understanding biofilm presence in these tissues is crucial for effective treatment.

Purpose of the Study:

  • To investigate the occurrence of biofilms on the epithelial surfaces of tonsils and adenoids in pediatric patients.
  • To determine if biofilm presence correlates with infection or obstruction in these tissues.

Main Methods:

  • Prospective study conducted at a tertiary academic hospital.
  • Inclusion of 76 children undergoing adenotonsillectomy (T&A) for infection or obstruction.
  • Assessment of biofilm presence using scanning electron microscopy.

Main Results:

  • Biofilms were detected in 61% of the patients studied.
  • A significantly higher prevalence of biofilms was observed in patients with tonsil and adenoid infections (85%) compared to those with obstruction only (41%).
  • The association between biofilms and infection was statistically significant (P = .01).

Conclusions:

  • Biofilms are frequently present on infected or enlarged tonsils and adenoids in children.
  • The findings indicate a strong association between biofilm formation and chronic inflammation in these tissues.
  • This suggests biofilms may play a role in the pathogenesis of chronic tonsillitis and adenoiditis.

Biofilms

Biofilms are complex communities of microorganisms encased in a self-produced extracellular polysaccharide matrix attached to surfaces. These microbial consortia can include single or multiple species, providing enhanced survival benefits by forming organized, multilayered structures.The formation of biofilms occurs through four key stages: attachment, colonization, development, and dispersal.During attachment, free-swimming planktonic cells adhere to a surface, often facilitated by...

Tonsillitis I: Introduction

Tonsillitis is inflammation of the tonsils, which are two lymphoid tissue masses at the back of the throat. This condition can cause discomfort and irritation in the throat.
Etiology
Three primary contributing factors have been identified.

Tonsillitis II: Management

This lesson will focus on the different treatment options for managing tonsillitis, which typically depend on the cause and severity.
Microbiota of the Respiratory Tract01:29

Microbiota of the Respiratory Tract

The human respiratory tract, comprising the upper and lower segments, serves as a critical interface with the external environment. The upper respiratory tract (URT)—including the nostrils, sinuses, pharynx, and oropharynx—is heavily colonized by microbes, while the lower respiratory tract (LRT), composed of the larynx, trachea, bronchi, and lungs, was long thought to be sterile. However, recent molecular studies have revealed that the lungs are not devoid of microbes but act more like...
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,...

Acute Pharyngitis

Introduction
Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
Classification
Acute pharyngitis can be categorized based on its underlying cause:
