Laryngopharyngeal reflux: A confounding cause of aerodigestive dysfunction
Background:
Laryngopharyngeal reflux (LPR) is one of the most common and important disorders of upper airway inflammation. It causes significant impairment to quality of life, and can predict serious laryngeal and oesophageal pathology, yet it remains under-diagnosed and under-treated.
Objective:
This paper attempts to unravel the diagnostic dilemma of LPR and provide a practical, discriminating approach to managing this common condition.
Discussion:
Historical red flags mandating early referral for specialist review are identified, and pathophysiology, symptomatology and common signs are reviewed. In addition, a comprehensive treatment plan consisting of lifestyle modifications, counselling aids and empirical medical therapy is proposed. A strategy for tracking clinical improvement using Belfasky's validated symptom index is included to aid counselling, compliance and follow-up.

Chronic Pharyngitis
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,...
Esophageal Strictures-I: Introduction
Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...
