Lead Poisoning In Baltimore, 4.6% of kids screened had high lead levels in 2006 Plumbism presents often with vague and nonspecific symptoms; however, have high index of suspicion if: ==> Listlessness, clumsiness, or loss of developmental skills, ==> Recurrent or intermittent abdominal pain, vomiting, and constipation ==> Afebrile Convulsions ==> Resides in a house built before 1950 ==> Family history of elevated lead ==> History of Pica ==> Iron Deficiency Anemia ==> Evidence of neglect/abuse Lead Level will not come back in a timely fashion to help direct care, therefore, presumptive Chelation may be warranted. Evidence to Support Lead Posioning: ==> Micorcytic Anemia ==> Elevated Erythrocyte Protoporphyrin ==> Basophilic stippling of erythrocytes ==> Glycosuria, aminoaciduria (from development of Fanconi s Syndrome) ==> Radiopaque flecks on AXR ==> Lead Lines (dense metaphyseal bands on knee and wrist x-rays) Chelation with CaEDTA, BAL, or DMSA depending on level and symptoms.
