Device for facilitating precise alignment in bedside radiography.

The difficulty associated with achieving precise alignment in a bedside radiographic setting has led many departments to abandon the use of a grid and forfeit the improved contrast it affords. The authors describe a method of alignment that has proved successful in overcoming the hazards of grid cut-off in a bedside setting. The method affords obtainment of reproducible high-quality bedside radiographs with a 10:1 linear grid.

Epidural peg electrodes for the presurgical evaluation of intractable epilepsy.

A new electrode design for the extradural recording of electrical brain activity is described. Epidural peg electrodes are implantable mushroom-shaped composites of Silastic elastomer and a stainless steel or platinum disc. These electrodes are useful for the preoperative mapping of seizure foci in some patients who have cranial defects or severe muscle artifacts on scalp recordings. They are also used for canvassing wide areas of cortex to determine whether a seizure is focal in origin, arises diffusely from a hemisphere, or has a bilateral origin. Advantages of epidural peg electrodes over screw and other types of epidural electrodes include low risk of infection or hemorrhage and improved patient comfort.
