Rasburicase-induced Methemoglobinemia: A Case Report and Literature Review.
2020
Rasburicase is a recombinant urate oxidase enzyme indicated for tumor lysis syndrome, a potential life-threatening oncologic emergency that occurs most commonly during initial chemotherapy for hematological malignancies. As a result of the defects in the physiological antioxidant pathway, erythrocytes of patients with glucose-6-phosphate dehydrogenase deficiency are not protected against the oxidizing stress exerted by hydrogen peroxide generated with the administration of rasburicase. The authors report a 14-year-old patient, diagnosed with T-cell acute lymphoblastic leukemia, who developed methemoglobinemia and hemolytic anemia with low oxygen saturation after starting steroids, hyperhydr…
Methemoglobinemia Associated with Late-Onset Neonatal Sepsis: A Single-Center Experience
2019
Objective Methemoglobinemia (MetHb) is a rare congenital or acquired cause of infantile cyanosis. We examined the role of MetHb in a neonatal intensive care unit (NICU). Study Design A retrospective observational study was conducted reviewing blood gas analyses of hospitalized newborns over a 2-year period. MetHb-positive patients (MetHb >1.8%) were matched with a control group for gestational age, weight, disease, and illness severity at admission. Maternal, neonatal, clinical, and laboratory parameters were collected and analyzed in both groups. Results MetHb incidence was 6%. The mean MetHb in the case group was 7.2%, and the first positive samples were observed at a mean of 22 days …
Agua de bebida en el lactante
2004
Se revisan tipos de aguas de consumo público y aguas de bebida envasadas. Se realizan recomendaciones sobre las características que debe reunir el agua destinada al lactante. Para la reconstitución correcta de todas las fórmulas de inicio comercializadas en España, el contenido en sodio debe ser menor de 25 mg/l. El agua de consumo público debe hervirse un máximo de 1 min (a nivel del mar) para evitar la excesiva concentración de sales. No precisa de ebullición el agua de bebida envasada. El nivel de flúor debe ser menor de 0,3 mg/l en el primer año de vida para evitar fluorosis. La concentración de nitratos en agua debe ser menor de 25 mg/l para evitar metahemoglobinemia. Aguas con una con…
