Nitrous Oxide 0-3 NADH:ubiquinone oxidoreductase subunit B3 Homo sapiens 70-73 32195121-3 2020 We report herein the case of a 13-year-old girl with sickle cell disease exhibiting severe neurological and biochemical signs of functional vitamin B12 deficiency due to prolonged and repeated exposure to N2O. Nitrous Oxide 205-208 NADH:ubiquinone oxidoreductase subunit B3 Homo sapiens 148-151 32195121-4 2020 This was an incentive to prospectively investigate functional vitamin B12 deficiency in patients affected by sickle cell disease regularly exposed to N2O. Nitrous Oxide 150-153 NADH:ubiquinone oxidoreductase subunit B3 Homo sapiens 70-73 32195121-7 2020 The clinical case highlight the potential severe deleterious effects of N2O over exposure on B12 vitamin metabolism in particular in patients affected with sickle cell disease. Nitrous Oxide 72-75 NADH:ubiquinone oxidoreductase subunit B3 Homo sapiens 93-96
