Insights

Pharyngeal acid reflux (PAR) is common in infants with laryngitis, even with treatment. Flexible laryngoscopy-guided pH monitoring reveals PAR not always detected by esophageal monitoring alone.

Area of Science:

  • Pediatric Otolaryngology
  • Gastroenterology
  • Pediatric Pulmonology

Background:

  • Laryngitis in infants can be associated with gastroesophageal reflux.
  • Assessing pharyngeal acid reflux (PAR) in infants is challenging.

Purpose of the Study:

  • To evaluate pharyngeal acid reflux (PAR) exposure using flexible laryngoscopy-guided pharyngeal pH monitoring in infants diagnosed with laryngitis.

Main Methods:

  • A retrospective review of 10 infants with laryngitis who underwent pharyngoesophageal pH monitoring was conducted.
  • Data collected included patient history, physical examination findings, and pH monitoring results.

Main Results:

  • Pharyngeal acid reflux (PAR) was detected in 6 out of 10 infants.
  • Acid exposure time in the pharynx ranged from 0.1% to 1.2%.
  • Esophageal acid reflux was present in 9 infants, with pharyngeal pH monitoring providing additional diagnostic information.

Conclusions:

  • The majority of infants with laryngitis exhibited pharyngeal acid reflux (PAR).
  • Esophageal acid reflux does not always extend to the pharynx.
  • Pharyngeal pH monitoring offers valuable insights beyond standard esophageal monitoring for infants with laryngitis.

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 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:
Pharynx01:20

Pharynx

The pharynx, a tubular structure framed by skeletal muscle and lined with mucous membrane, extends continuously from the nasal cavities. It is segmented into three major areas: the nasopharynx, oropharynx, and laryngopharynx.
Nasopharynx
The nasopharynx, bordered by the conchae of the nasal cavity, serves exclusively as an air conduit. In its superior region, the pharyngeal tonsils or adenoids are located. These tonsils are clusters of lymphoid reticular tissue akin to a lymph node. The precise...
Suctioning the Oropharyngeal Airway01:25

Suctioning the Oropharyngeal Airway

In preparing for oropharyngeal airway suctioning, a nurse must gather all necessary equipment, including a suction unit with tubing, a prepackaged suction kit, sterile gloves, water or saline for irrigation, a water-soluble lubricant, and additional personal protective equipment (such as a gown, mask, and goggles) to control infections.
After assembling the equipment, the nurse should practice hand hygiene and don appropriate PPE according to infection control guidelines to avoid the...

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...
