Insights

Dacryocystitis, a rare complication of infectious mononucleosis (also known as Epstein-Barr virus infection), can rapidly progress to severe orbital cellulitis. Prompt surgical intervention may be necessary for effective treatment.

Area of Science:

  • Ophthalmology
  • Infectious Diseases
  • Pediatrics

Background:

  • Infectious mononucleosis can cause various complications, including tonsillar hyperplasia.
  • Dacryocystitis, an inflammation of the tear sac, is a rare but serious complication of infectious mononucleosis.

Observation:

  • A 6-year-old child presented with acute dacryocystitis eight days after infectious mononucleosis diagnosis.
  • The condition rapidly evolved into orbital cellulitis despite antibiotic treatment.

Findings:

  • Dacryocystitis is an uncommon complication of Epstein-Barr virus (EBV) infection.
  • Acute dacryocystitis can rapidly progress to severe orbital cellulitis.
  • Pathophysiology involves acute obstruction of the lacrimal sac due to lymphoid hyperplasia.

Implications:

  • Early recognition of dacryocystitis in EBV infection is crucial.
  • Prompt surgical drainage may be required for severe cases.
  • Understanding the specific pathophysiology aids in managing this rare complication.

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:
Cryptococcal Meningitis01:27

Cryptococcal Meningitis

Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...
Cytomegalovirus Disease01:27

Cytomegalovirus Disease

Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...
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.

Tonsillitis II: Management

This lesson will focus on the different treatment options for managing tonsillitis, which typically depend on the cause and severity.
Diphtheria01:28

Diphtheria

Diphtheria is an acute, toxin-mediated infectious disease that primarily affects the upper respiratory tract. It is caused by Corynebacterium diphtheriae, a Gram-positive, pleomorphic rod that lacks spore-forming capability and exhibits a characteristic club-shaped morphology under microscopic examination. While C. diphtheriae can asymptomatically colonize mucosal surfaces, clinical disease manifests only when the bacterial strain is lysogenized by a specific β-corynephage. This phage...
