Bacterial flora on slit lamps.

The slit lamp can be a source of cross infection in the clinic setting. We identified the bacteria flora on slit lamps and determined the risk of transmission to patients. Frequent cleaning of the slit lamp especially after treating infected cases can decrease the transmission of organisms.

A serious pain in the neck.

We describe a case of internal carotid artery dissection, an important cause of ischemic cerebrovascular disease. Presentations include a headache, which is usually unilateral to the side of carotid dissection, sharp, nonthrobbing in nature with radiation from the neck.
