Are specific abbreviated injury scale values responsible for the underestimation of mortality in penetrating trauma patients by the injury severity score?
Significant differences in mortality between blunt and penetrating trauma patients exist at certain ISS and AIS category values. The mortality difference is greatest for head injured patients.
Certain clinical differences were observed comparing AIDS patients with HIV1 and those with HIV2 infection. As there is no clear physiopathological explanation for these differences, additional studies with larger numbers of AIDS patients are needed to determine whether these differences are real.
