Selective deep peroneal nerve injury associated with arthroscopic knee surgery.

We report 3 cases of isolated deep peroneal nerve injury as a complication of arthroscopic knee surgery. At the level of the knee joint, the deep and superficial peroneal nerves are usually joined as the common peroneal nerve. However, because of the fascicular structure, a partial nerve injury can result in an isolated injury to the deep peroneal nerve fibers.

Nosocomial stroke.

Nosocomial stroke occurs during hospitalization for unrelated problems. Increased understanding of this relatively ignored entity may provide the key to improved stroke prophylaxis for the hospitalized patient at risk and provide clues to the precipitants of stroke in the general population. We compared nosocomial stroke to stroke occurring outside the hospital in a mixed prospective and retrospective analysis of 372 consecutive strokes occurring over 2 years.

Use of CT in epilepsy: does it matter how long you wait?

Computer tomography (CT) of the brain is of value for finding potentially correctable lesions in adult patients with new onset seizures. The value of CT is unknown, however, for finding such lesions in adult chronic epileptic patients without prior CT. We compared a group of 177 adult patients who had CT within a year from the onset of seizures to a group of 93 patients who had a history of seizures for more than a year before CT was performed.
