Abstract

To determine whether serum iron concentrations correlate with the development of symptoms of iron poisoning in children. A retrospective study of medical records from January 1976 through June 1992. A tertiary care children's medical center. Criteria for patient selection included an acute ingestion of iron-containing drugs, measurement of serum iron prior to deferoxamine administration, and a serum iron concentration (obtained within 2-9 hours of exposure) that was greater than 150 micrograms/dl (27 mumol/L). Of the 128 children who were hospitalized for acute iron poisoning, 92 patients (mean age 2.3 +/- 2.2 years) met the selection criteria. None. The mean (+/-SD) serum iron concentrations (microgram/dl) of patients who exhibited cardiovascular instability (725 +/- 555, n = 6; p < 0.001) differed from those categorized with central nervous system changes (373 +/- 77, n = 30), gastrointestinal symptoms (334 +/- 83, n = 44), and no symptoms (368 +/- 102, n = 12). Serum iron concentrations in patients with cardiovascular instability ranged from 205-500 micrograms/dl (37-269 mumol/L), whereas those with no symptoms ranged from 170-513 micrograms/dl (30 to 92 mumol/L) demonstrating considerable overlap of ranges. Serum iron conce...Continue Reading

Anemia

Anemia develops when your blood lacks enough healthy red blood cells. Anemia of inflammation (AI, also called anemia of chronic disease) is a common, typically normocytic, normochromic anemia that is caused by an underlying inflammatory disease. Here is the latest research on anemia.
