(serum). Although Berger et al3 only investigated changes

in serum levels, it would be prudent to evaluate total body losses in lieu of daily intake. Voruganti et al4 evaluated the serum and exudative losses of zinc and copper. Their find-ings revealed that exudative losses of zinc and copper were greater than the serum concentrations, suggesting that supplementation (3 times dietary reference intake) may not provide adequate serum concentrations in presence of exudative losses. In the study by Voruganti et al4, the non-significant increases in serum zinc levels could have been explained if the authors had provided evidence of exudative losses. Although Barbosa et al5 only investigated serum and clinical end points up to 7 days following thermal injury, Berger et al6 investigated outcomes at 30 days after thermal injury in 40 adult patients receiving standard trace elemen
