ANGINA PELLICULARIS Meaning and
Definition
-
Angina pellicularis is a medical term that refers to a type of acute inflammation or coating of the throat that is characterized by the formation of a grayish-white membrane. The condition is commonly known as membranous angina or diphtheria.
Angina pellicularis typically affects the throat and tonsils, where a thin, fibrous membrane develops and adheres to the affected area. This membrane is composed of necrotic tissue, inflammatory cells, and fibrin. It may cover small or large areas of the throat and tonsils, causing discomfort and difficulty in swallowing. The membrane can be easily removed, but its reappearance is common.
The underlying cause of angina pellicularis is usually a bacterial infection, specifically the bacteria Corynebacterium diphtheriae. This disease is contagious and can spread through respiratory droplets or direct contact with an infected individual. The bacteria release toxins that can cause local inflammation and tissue damage, leading to the formation of the distinct membrane seen in angina pellicularis.
If left untreated, angina pellicularis can lead to severe complications, such as airway obstruction, heart problems, kidney damage, and paralysis. Therefore, immediate medical attention is crucial. Treatment typically involves the administration of antibiotics, antitoxin, and supportive care to ensure the removal of the membrane and control the infection. Vaccination against diphtheria is also an effective preventive measure against the disease.
Overall, angina pellicularis is a serious condition characterized by the formation of a grayish-white membrane in the throat due to a bacterial infection. Prompt medical intervention is essential to prevent complications and facilitate a swift recovery.
Etymology of ANGINA PELLICULARIS
The term "Angina pellicularis" consists of two Latin words: "angina" and "pellicularis".
1. "Angina": The word "angina" derives from the Latin word "angere", meaning "to cause constriction" or "to strangle". It was originally used to describe a condition characterized by severe chest pain or tightness caused by a lack of blood flow to the heart muscles (known as angina pectoris).
2. "Pellicularis": The word "pellicularis" comes from the Latin word "pellis", meaning "skin" or "membrane". In medical terminology, "pellicularis" is added to a word to indicate a condition related to or resembling a skin or membrane.
