Table 1. Factors Predisposing to Catheter Related Infection Length of time catheter is in place Poor preparation and insertion technique Pre-existing Infection Surgical placement Local catheter care and dressing changes Frequent manipulation lmmunocompromised host Multi-lumen catheters present and invasive cannulation is still necessary, a new site should be selected for access. Daily dressing changes and local catheter care with application of neomycin-bacitracinpolymixin ointment is standard care for prevention of infection. When C R I are diagnosed, removal of the indwelling percutaneous catheter and administration of antimicrobial agents based on culture and suscep-

tibility tests constitutes appropriate therapy.

Pediatrics 78:678-687, 1986. Among 36 children with human immunodeficiency virus (HIV) infections, progressive encephalopathy developed in 16 of 21 children with acquired immunodeficiency syndrome (AIDS), three of 12 children with A I D S related complex (ARC), and one of three asymptomatic seropositive children. Neurologic abnormalities were often detected early, and worsened with progression of the immunodeficiency. Progressive encephalopathy correlated with the absence of serum neutralizing antibodies to HIV and with a poor, usually fatal, outcome. Incubation periods ranged from 2 months to 5 years from initial HIV infection in the perinatal

period to the onset of progressive encephalopathy. Synthesis of HIV specific antibodies within the central nervous system (CNS) was demonstrated in 8 of 14 children with A I D S or ARC, indicating active brain infection with HIV. Unique neuropathologic findings in children who died with HIV infection suggested that the progressive encephalopathy was a result of primary and persistent infection of the brain with HIV.

and in one child still asymptomatic but seropositive. Brain infection in these children probably occurred early and was persistent. The presence of the virus within the brain has therapeutic implications, ie, an effective anti-HIV agent will need to cross the blood brain barrier unless it is administered before CNS involvement has occurred.

Comment Acquired immunodeficiency syndrome, in both adults and children is frequently accompanied by neurologic dysfunction. Epstein et al. report that progressive encephalopathy occurred in more than 50% of children with HIV infection. Most of the children also had AIDS, although the encephalopathy also developed in children with ARC,
