Vibratory angioedema

Vibratory Angioedema (pronunciation: vahy-bruh-tawr-ee an-gee-oh-ed-uh-muh) is a rare form of physical urticaria characterized by the rapid onset of skin swelling and redness upon exposure to vibratory stimuli.

Etymology

The term "Vibratory Angioedema" is derived from the Latin word "vibrare" meaning "to shake" and the Greek words "angeion" meaning "vessel" and "oídēma" meaning "swelling".

Symptoms

The primary symptom of Vibratory Angioedema is the rapid onset of skin swelling and redness upon exposure to vibratory stimuli. Other symptoms may include itching, burning, and discomfort in the affected area.

Causes

Vibratory Angioedema is caused by exposure to vibratory stimuli such as using power tools, riding in a vehicle on a rough road, or even clapping hands. The exact mechanism of how vibration triggers the symptoms is not fully understood, but it is believed to involve the release of histamine from mast cells in the skin.

Diagnosis

Diagnosis of Vibratory Angioedema is typically based on the patient's history of symptoms following exposure to vibratory stimuli. A vibration challenge test can be performed to confirm the diagnosis.

Treatment

Treatment for Vibratory Angioedema primarily involves avoiding exposure to vibratory stimuli. Medications such as antihistamines may be used to manage symptoms. In severe cases, a medication called omalizumab may be used.
