Résumé : To the author's regret, there is a mistake in Table 9 (recommended daily doses of trace elements for parenteral nutrition) regarding the conversion of the doses for copper and selenium to mcmols. Replace 4.7–9.6 by 4.7–7.9 mcmol (0.3–0.5 mg) for copper and 0.2–0.8 by 0.8–1.3 mcmol (60–100 mcg) for selenium, respectively. We apologise for any inconvenience caused.
