Subclinical injury to forearm nerves during radial harvesting: electrophysiologic study.

Background And Aim: There are few reports about injury to forearm nerves and its potential mechanisms during radial artery (RA) harvesting. We studied electrophysiologic changes in these nerves not sought until now.

Methods: Among 152 consecutive patients who underwent coronary artery bypass surgery between February 2002 and August 2002, 20 were randomized for RA harvesting and formed the study group and 20 were randomized as control group.

Auditory event-related brain potentials in fibromyalgia syndrome.

Objective: The aim of this study was to investigate cognitive functions using auditory event-related brain potentials (ERP) in fibromyalgia syndrome (FMS).

Methods: The P300 component of ERP was studied in 36 female FMS patients and 22 control subjects. The short form 36 (SF-36) medical outcome study was used to determine quality of life.

Paraplegia associated with brucellosis involving the anterior lumbrosacral nerve roots.

We report the case of a 21-year-old man with paraplegia due to brucellosis involvement of lumbosacral anterior roots. Lumbosacral magnetic resonance imaging showed contrast enhancement of anterior roots and the anterior part of duramater. Conduction block was found at the level of the lumbosacral anterior roots by electrophysiological studies, including magnetic stimulation study.
