 The patient is a 2-year, 2-month-old little girl who presented to the hospital with severe anemia, hemoglobin 5.8, elevated total bilirubin consistent with hemolysis and weak positive direct Coombs test.  She was transfused with packed red blood cells.  Her hemolysis seemed to slow down.  She also on presentation had indications of urinary tract infection with urinalysis significant for 2+ leukocytes, positive nitrites, 3+ protein, 3+ blood, 25 to 100 white cells, 10 to 25 bacteria, 10 to 25 epithelial cells on clean catch specimen.  Culture subsequently grew out no organisms; however, the child had been pretreated with amoxicillin about x3 doses prior to presentation to the hospital.  She had a blood culture, which was also negative.  She was empirically started on presentation with the cefotaxime intravenously.  Her white count on presentation was significantly elevated at 20,800, subsequently increased to 24.7 and then decreased to 16.6 while on antibiotics.  After antibiotics were discontinued, she increased over the next 2 days to an elevated white count of 31,000 with significant bandemia, metamyelocytes and myelocytes present.  She also had three episodes of vomiting and thus she is being taken to the procedure room today for a lumbar puncture to rule out meningitis that may being inadvertently treated in treating her UTI.
