Abstract
MARTINEZ RIERA, Nora et al. Lead intoxication: clinic and diagnostic evaluation in children. Rev. Cienc. Salud [online]. 2012, vol.10, suppl.1, pp.9-15. ISSN 1692-7273.
Poverty, poor nutrition, environmental and social injustice prevailing in Latin America are factors that determine the action of pollutants on children. Lead poisoning and pollution constitute a public health problem throughout the world. Lead affects multiple organs: nervous system particularly, hematopoietic, renal, endocrine, bone and others. Objective: to assess clinical, biochemical and vascular effects in children exposed to known source of lead. Materials and methods: Seven children with defined source lead exposure were studied, general and specific lead laboratory were made. Endothelial function and electrocardiographic parameters were assessed. Statistic: descriptive. Results: Age average was 6,2 years (DE± 1, 6), average haematocrit 31% (DE±0,02); hemoglobin average 10,2 g/dl (DE± 0,78). 100% presented hypochromia, microcitosis, anemia and marked anisocytosis. Lead average: 37,9 ug/dl (DE±6,22), ALA-D average: 8,9 U/L (DE±4,5). No changes were found in lipid profile and kidney function. All presented microalbuminuria and endothelial dysfunction. Conclusion: These results show the effects of environmental lead exposure that can result in children not occupationally exposed.
