Pyrogenic reactions in patients undergoing cardiac catheterization associated with contaminated glass medicine cups.

Pyrogenic reactions are potentially life-threatening complications caused by bacterial endotoxin. After two cardiac catheterization patients developed rigors the same day, the procedures were halted and a case control study was conducted. To identify case patients (persons with rigors < or = 3 hr after catheterization during September 25-November 9, 1995), we reviewed medical records of all cardiac catheterization patients who had a blood culture or received intravenous meperidine.

The anatomic organization of evoked potentials in rat parietal cortex: electrically evoked commissural responses.

1. Two 8 x 8 channel microelectrode arrays were positioned over 3.5 x 3.

Anatomic organization of evoked potentials in rat parietotemporal cortex: somatosensory and auditory responses.

1. Two 8 x 8-channel microelectrode arrays were used to map epicortical field potentials from a 3.5 x 3.
