Acute Pharyngitis01:30

Acute Pharyngitis

2.4K
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:

Chronic Pharyngitis01:23

Chronic Pharyngitis

7.6K
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,...

Tonsillitis I: Introduction

889
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.

Pneumonia I: Introduction01:30

Pneumonia I: Introduction

463
Pneumonia is an acute respiratory infection that targets the lungs, specifically the alveoli. These tiny air sacs, essential for oxygen exchange, become engorged with pus and fluid, severely hindering breathing, decreasing oxygen absorption, and causing significant pain and discomfort during respiration.
Risk Factors
Various factors influence the likelihood of developing pneumonia. Age plays a crucial role, with infants, children under two, and individuals over 65 at increased risk due to their...

Area of Science:

  • Infectious Diseases
  • Virology
  • Otolaryngology

Background:

  • Coronavirus 2019 (COVID-19) predominantly causes respiratory illness.
  • Atypical presentations of COVID-19 are increasingly recognized.
  • Parotitis, or inflammation of the parotid salivary glands, is a rare manifestation.

Observation:

  • A 46-year-old male presented with fever but no respiratory symptoms.
  • The patient subsequently developed bilateral parotitis.
  • A literature review identified other cases of COVID-19-associated parotitis.

Findings:

  • COVID-19 should be considered in the differential diagnosis of parotitis.
  • Common features across reported cases of COVID-19-related parotitis were identified.
  • Parotitis can occur in the absence of typical respiratory symptoms.

Implications:

  • Early recognition of parotitis as a COVID-19 symptom is crucial for patient management.
  • Implementing appropriate infection control measures is essential.
  • This broadens the clinical spectrum of known COVID-19 manifestations.
