Which disease can result in a pseudomembrane that covers the tonsils pharynx and larynx?
Corynebacterium diphtheriae produces a gray pseudomembrane in the pharynx and larynx, which may lead to respiratory obstruction and sudden death.
In which condition does a pseudomembrane covering the tonsils?
The classic case of diphtheria is an upper respiratory infection caused by bacteria. It produces a gray pseudomembrane, or a covering that looks like a membrane, over the lining of the nose and throat, around the area of the tonsils.
In which disease does a tough pseudomembrane obstruct the airway?
Initial symptoms of illness include a sore throat, difficulty in swallowing, malaise, and low-grade fever. The hallmark of respiratory diphtheria is the presence of a tough, grayish-white pseudomembrane over the tonsils, nasopharynx, or larynx.
What is pseudomembrane formation?
A pseudomembrane is formed when inflammatory exudate rich in fibrin coagulates on the conjunctiva. This is seen as a thin yellow-white membrane in the fornices and palpebral conjunctiva that can be readily peeled off, leaving an intact underlying epithelium with minimal bleeding.
What disease causes a pseudomembrane?
The most common cause of pseudomembranes is epidemic keratoconjunctivitis, or EKC Epidemic Keratoconjunctivitis (EKC) is a contagious eye infection, often referred to as viral conjunctivitis. EKC is an inflammation of the cornea and conjunctiva.
What disease of the respiratory system includes the formation of a pseudomembrane in the throat?
Diphtheria is an acute, communicable disease caused by Corynebacterium diphtheriae. The disease is generally characterized by local growth of the bacterium in the pharynx with pseudomembrane formation or, less commonly, in the stomach or lungs; systemic dissemination of toxin then invokes lesions in distant organs.
In which condition does a pseudomembrane?
What is Pseudomembrane?
Pseudomembranous (SOO-doe-mem-bruh-nus) colitis, also called antibiotic-associated colitis or C. difficile colitis, is inflammation of the colon associated with an overgrowth of the bacterium Clostridioides difficile (formerly Clostridium difficile) — often called C. diff.
Which diseases are commonly shown Pseudomembrane?
Introduction. Pseudomembranous colitis (PMC) is a manifestation of severe colonic disease that is usually associated with Clostridium difficile infection, but can be caused by a number of different etiologies.
What does a pseudomembrane look like?
The pseudomembrane is characterized by the formation of a dense, gray debris layer composed of a mixture of dead cells, fibrin, RBCs, WBCs, and organisms; the pseudomembrane is shown in the image below. The characteristic thick membrane of diphtheria infection in the posterior pharynx.
What is pseudomembrane?
What is a pseudomembrane in the mouth?
Within two to three days, the dead tissue forms a thick, gray coating that can build up in the throat or nose. Medical experts call this thick, gray coating a “pseudomembrane.” It can cover tissues in the nose, tonsils, voice box, and throat, making it very hard to breathe and swallow.
