Insights

Retropharyngeal abscess (RPA) cases have significantly increased, with a notable rise in Group A beta-hemolytic streptococcus (GABHS) infections. Treatment involved antibiotics and drainage, leading to full recovery in all pediatric patients.

Area of Science:

  • Pediatric Infectious Diseases
  • Otolaryngology
  • Microbiology

Background:

  • Retropharyngeal abscess (RPA) incidence has recently increased in pediatric hospital admissions.
  • A 4.5-fold rise in RPA cases was observed over an 11-year period (1993-2003).
  • The majority of cases occurred within the latter four years of the study period.

Purpose of the Study:

  • To review the incidence of retropharyngeal abscess (RPA) in children.
  • To analyze the microbiology of pediatric RPA cases.
  • To evaluate treatment outcomes for pediatric RPA.

Main Methods:

  • Retrospective review of medical records for children diagnosed with RPA.
  • Analysis of microbiological data from abscess specimens.
  • Review of treatment regimens and patient outcomes.

Main Results:

  • Sixty-seven pediatric RPA cases were identified, showing a 4.5-fold increase in incidence.
  • Computed tomography confirmed inflammatory or ring-enhancing lesions in all patients.
  • Group A beta-hemolytic streptococcus (GABHS) was recovered in 54% of specimens, a significant increase from previous periods.
  • Treatment included intravenous and oral antibiotics, with abscess drainage in 76% of cases.
  • All patients achieved a full recovery.

Conclusions:

  • Retropharyngeal abscess (RPA) is an increasing polymicrobial infection in children.
  • A significant association was found between increased RPA incidence and higher recovery rates of GABHS.
  • Further investigation is needed to determine if increased GABHS strain invasiveness contributes to the rising incidence.

Streptococcal Pharyngitis01:27

Streptococcal Pharyngitis

Streptococcal pharyngitis, commonly known as “strep throat,” is an acute infection of the oropharyngeal tissues caused by the Gram‑positive Group A Streptococcus (Streptococcus pyogenes). Transmission occurs primarily through respiratory droplets expelled during coughing, sneezing, or talking.Mechanisms of Host Entry and Immune EvasionUpon entering the host, S. pyogenes adheres to the mucosal epithelial cells of the pharynx via surface proteins, notably lipoteichoic acid and the antiphagocytic...
Acute Pharyngitis01:30

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:
Tonsillitis I: Introduction01:30

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.
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...
Brain Abscess l: Introduction01:26

Brain Abscess l: Introduction

A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial infections,...
Staphylococcal Skin Infections01:29

Staphylococcal Skin Infections

Staphylococcus aureus is a Gram-positive coccus that resides harmlessly on the skin and mucous membranes of healthy individuals. When the skin barrier is breached, it can shift from a commensal to an opportunistic pathogen. This transition is facilitated by surface adhesins, such as clumping factor B and S. aureus surface protein G (SasG), which bind to structural proteins, including loricrin and cytokeratin, in the damaged epidermis. Protein A, another key factor, binds the Fc region of...
