This review evaluates the antiviral, antioxidant, and immunostimulatory properties of green tea catechins. Two randomized trials evaluating the activity and efficacy of green tea catechins in the management of external genital warts are presented, and the reported side effects associated with this topical treatment modality are outlined. Finally, the mechanism of action, percent of wart clearance, time to clearance, and toxicity profile of green tea catechins are compared with those of podofilox and imiquimod, 2 other patient-administered topical agents approved for treatment of anogenital warts.

Aortic arch atherosclerosis is associated with an increased risk of stroke or TIA. Up to now, transesophageal echocardiography has been the standard method for diagnosing protruding and/or mobile aortic arch atherosclerosis. We report a case where a mobile aortic arch atheroma was diagnosed using transthoracic echo in a patient with a recent stroke.
