title: Potentially clinically toxic concentrations of whole blood manganese in a patient fed enterally with a high tea consumption.
abstract: This report describes a 37-year-old female patient who after seven years on intermittent overnight enteral feeding supplementation was noted to have an increased whole blood manganese concentration. Manganese toxicity is well documented after pathological absorption through inhalation via the lungs, or after intravenous administration to patients on long-term total parenteral nutrition. A dietary history revealed high tea consumption. The association between high blood manganese concentrations and enteral/oral nutrition does not appear to have previously been described.
