Definition
  1. Noun:
    • A severe medical condition: Waterhouse-Friderichsen syndrome is a rapidly progressing syndrome most commonly associated with overwhelming bacterial infection, typically meningococcal meningitis. It is characterized by a sudden onset of high fever, a characteristic skin rash (including discoloration and petechiae), hemorrhage into the adrenal glands, and profound cardiovascular collapse (shock).
Usage
  • The term is used exclusively as a medical noun to name this specific, acute clinical condition.
  • It is typically used in formal medical, clinical, and pathological contexts (e.g., diagnosis, case reports, medical literature).
  • Example: "The patient's rapid deterioration, with petechiae and shock, led to a suspicion of Waterhouse-Friderichsen syndrome."
Examples
  • Noun:
    • The autopsy revealed bilateral adrenal hemorrhage, confirming the diagnosis of Waterhouse-Friderichsen syndrome.
    • Waterhouse-Friderichsen syndrome is a life-threatening complication of certain bacterial infections.
    • Emergency treatment for Waterhouse-Friderichsen syndrome includes aggressive antibiotic therapy and supportive care for shock.
Advanced Usage
  • The syndrome is often discussed in the context of its pathophysiology, involving adrenal apoplexy (sudden bleeding into the adrenal glands) and disseminated intravascular coagulation (DIC).
  • It serves as a classic example of acute adrenal insufficiency (Addisonian crisis) triggered by infection.
Variants and Related Words
  • Adrenal hemorrhage: A key pathological finding in this syndrome.
  • Fulminant meningococcemia: A severe form of meningococcal infection that frequently leads to this syndrome.
  • Purpura fulminans: A condition involving severe skin bleeding and necrosis, often seen in conjunction with this syndrome.
Synonyms
  • Fulminant meningococcal sepsis (a common cause, though not a perfect synonym as the syndrome can have other causes).
  • Acute meningococcemia (context-specific).
Notes on Meaning
  • This is a highly specific medical term with a single, precise meaning. It is an eponym, named after physicians Rupert Waterhouse and Carl Friderichsen.
  • It is not used in general or figurative language.
Noun
