Cogan Syndrome
Cogan syndrome is a rare inflammatory condition thought to involve the immune system, affecting the eyes and the inner ear. It typically causes red, painful eyes from corneal inflammation along with hearing loss, vertigo and ringing in the ears. Some people also develop inflammation of blood vessels. Treatment usually involves steroids and other immune-suppressing medicines, with early hearing care important.

Most Recent Research
This case series reports on three female patients who developed the clinical symptoms of Cogan syndrome (ocular and audiovestibular syndrome) in temporal association with postpartum hemorrhage and successful hemostasis using a chitosan tamponade. All three patients showed the constellation of symptoms typical for Cogan syndrome, i.e., interstitial keratitis, (pan)uveitis, vertigo and loss of hearing. Headaches were also present. In the reported cases the uveitis rapidly improved under local and systemic steroid treatment but the audiovestibular symptoms and cephalgia showed a delayed response. The temporal association and consistent symptom complex are suggestive of a possible association with the preceding childbirth and the chitosan tamponade. Against this background, a chitosan tamponade should be avoided, when possible from an obstetric perspective, and when one has been used a possible association to the described disease picture should always be considered. Affected patients should receive interdisciplinary care at an early stage by including ophthalmology, obstetrics, otorhinolaryngology and rheumatology.
