Hutchinson's triad
Hutchinson's Triad
Hutchinson's triad (pronunciation: /hʌtʃɪnsən's traɪæd/) is a set of three medical signs typically associated with congenital syphilis. The triad is named after Sir Jonathan Hutchinson, a British surgeon and pathologist who first described the symptoms.
Etymology
The term "Hutchinson's triad" is derived from the name of its discoverer, Sir Jonathan Hutchinson, and the Greek word "triad", which means a group of three. The term was first used in medical literature in the late 19th century.
Signs
Hutchinson's triad consists of the following three signs:
1. Hutchinson's teeth: Notched, peg-shaped upper central incisors. 2. Interstitial keratitis: Inflammation of the cornea, which can lead to vision problems. 3. Sensorineural hearing loss: Hearing loss caused by damage to the inner ear or the nerve that sends sound to the brain.
