Abstract

To report a case of Polyarteritis Nodosa (PAN) presenting as bilateral episcleritis and interstitial keratitis along with erythema nodosum and atrial fibrillation and to review the ophthalmic literature on PAN with anterior segment findings. A 35-year old man presented with a two-month history of bilateral episcleritis, skin lesions consistent with erythema nodosum, joint effusions and episodes of prolonged diarrhea and atrial fibrillation. Ophthalmic examination was significant for bilateral diffuse episcleral injection and nummular corneal stromal infiltrates. The patient underwent an extensive infectious and inflammatory work-up that was negative except for a very elevated erythrocyte sedimentation rate (123 mm/h, normal < 20 mm/h) and C-reactive protein (51 mg/L, normal < 5 mg/L). In order to rule out inflammatory bowel disease upper endoscopy and colonoscopy were performed. Biopsies of the gastrointestinal mucosa were positive for a small- and medium-vessel necrotizing vasculitis consistent with polyarteritis nodosa. Disease control was achieved with systemic prednisone and azathioprine. Upon self-tapering both medications the patient developed hearing loss and interstitial keratitis recurred, hence the diagnosis of Cogan'...Continue Reading

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Auditory Perception

Auditory perception is the ability to receive and interpret information attained by the ears. Here is the latest research on factors and underlying mechanisms that influence auditory perception.
