Insights

A fully vaccinated child was misdiagnosed with laryngotracheobronchitis but actually had Haemophilus influenzae type B epiglottitis. Vaccination does not guarantee protection and can complicate diagnosis, posing life-threatening risks.

Area of Science:

  • Pediatrics
  • Infectious Diseases
  • Vaccinology

Background:

  • Haemophilus influenzae type B (Hib) infections can cause severe upper airway obstruction.
  • Hib vaccination is a standard preventative measure in childhood.
  • Accurate diagnosis is critical for managing airway emergencies.

Observation:

  • A 20-month-old child presented with acute upper airway obstruction requiring intensive care.
  • The child had completed the recommended Hib vaccine series.
  • Initial presumptive diagnosis was acute laryngotracheobronchitis.

Findings:

  • The child was ultimately diagnosed with acute epiglottitis caused by Hib.
  • The presumptive diagnosis of laryngotracheobronchitis was incorrect.
  • Hib epiglottitis occurred despite complete Hib vaccination.

Implications:

  • Complete Hib vaccination does not confer absolute immunity against Hib disease.
  • Hib vaccination may alter the clinical presentation of invasive Hib infections.
  • Misdiagnosis due to vaccination status can lead to delayed or inappropriate treatment, with potentially fatal outcomes.

Overview
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:
Poliomyelitis01:17

Poliomyelitis

Poliomyelitis is caused by poliovirus, a small, non-enveloped, positive-sense RNA virus of the Picornaviridae family and Enterovirus genus. Transmission occurs primarily via the fecal-oral route, often through ingestion of contaminated water or food. The virus initially replicates in the oropharynx and intestinal mucosa, particularly in lymphoid tissues such as the tonsils, Peyer’s patches, and regional lymph nodes. Primary viremia follows, allowing dissemination throughout the body.In most...
Viral Meningitis01:18

Viral Meningitis

Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...
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...
Bacterial Meningitis I: Introduction01:22

Bacterial Meningitis I: Introduction

Bacterial meningitis is a severe, life-threatening inflammation of the meninges, particularly the pia mater and arachnoid mater, affecting the subarachnoid space, ventricles, and cerebrospinal fluid (CSF). If untreated, it can lead to significant neurological complications or death.Causative AgentsCommon pathogens vary with age and immune status. In adults, major organisms include Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae. Streptococcus agalactiae (group B...
