    Phantom Sensations Generated by
    Thalamic Microstimulation.
    Nature 391: 386-387, 1998.
       
    Thalamic neuronal responses
    and stimulation induced sensations were analysed in
    patients with postamputation pain to gain better
    understanding of the thalamic mechanisms underlying
    phantom sensations.
       
    Thalamic mapping demonstrated an
    unusually large thalamic stump representation.
        
    More research is needed to
    further define the electrode activity in the thalamus
    and to assess potential pharmacologic or stereotactic
    interventions.

    Does Bacteremia Occur During High
    Pressure Lavage of Contaminated Wounds.
    Clin Orthop 347: 117-121. 1998
     
    This study on 20 dogs
    investigates the risk of bacteremia secondary to high
    pressure lavage of contaminated wounds.
     
    The dogs were divided randomly
    into 4 groups. In groups A and B, the
    wound was contaminated with 1.4 
    x 10 9 staphylococcus aureus and
    were followed 75 minutes later with high pressure
    lavage or bulb syringe irrigation.
    Groups C and D underwent the same treatment but
    without contamination.
     
    No
    detectable bacteremia occurred in the contaminated
    wounds. However bacteremia was
    detected in 18 of 20 control dogs.
    High pressure lavage reduced bacterial levels
    by 70% and bulb irrigation by 44%.
     
    It
    is concluded that high pressure lavage reduced wound
    bacteria more consistently than bulb irrigation
    did.
