Angioneurotic edemas refers to a medical condition characterized by sudden swelling of skin, mucosa, and submucosal tissues due to an allergic reaction. The word is spelled using the International Phonetic Alphabet (IPA) phonetic transcription, which represents the sounds of each letter in the word. The correct pronunciation of angioneurotic edemas is /eɪndʒiəʊnjʊrətɪk iːdɪməz/, with stress on the second syllable. Proper spelling and pronunciation are essential for effective communication in the medical profession.
Angioneurotic edema, also known as angioedema, is a medical condition characterized by swelling and inflammation affecting the skin's deeper layers, mucous membranes, and submucosal tissues. It is a localized swelling that typically occurs around the face, lips, tongue, throat, and genital region.
Angioneurotic edema is caused by the rapid release of histamine and other chemical mediators from mast cells and basophils, resulting in the dilation of blood vessels and increased permeability of the surrounding tissues. This vascular leakage leads to the accumulation of fluid and subsequent swelling.
The condition can manifest as sudden, painless, and non-pruritic (non-itchy) swelling that may last from a few hours to several days. In severe cases, angioneurotic edema can cause difficulty breathing, affecting the airway and potentially leading to life-threatening situations.
Angioneurotic edema can have different triggers, including allergic reactions to foods, medications, insect bites, or environmental factors. It can also occur due to non-allergic causes, such as genetic factors or certain medical conditions like autoimmune disorders or hormonal imbalances.
Treatment for angioneurotic edema may involve antihistamines, corticosteroids, or epinephrine to counteract the allergic response and reduce swelling. In some cases, patients may require emergency medical intervention, particularly if there is airway involvement.
Overall, angioneurotic edema is a potentially serious condition characterized by sudden and localized swelling caused by increased permeability of blood vessels due to histamine release. It can be triggered by allergic or non-allergic factors and may require prompt medical attention.
The word "angioneurotic edemas" is a medical term used to describe a condition known as angioedema. The etymology of this term is as follows:
1. Angio-: Derived from the Greek word "angeion", meaning "vessel" or "blood vessel".
2. Neurotic: Derived from the Greek word "neuron", meaning "nerve", combined with the suffix "-otic", which indicates a relationship or condition associated with.
3. Edema: Derived from the Greek word "oidema", meaning "swelling" or "tumor".
Therefore, "angioneurotic edemas" refers to the swelling or edema of blood vessels due to a nerve-related condition.
