Caracterização das alterações de linguagem em crianças com histórico de intoxicação por chumbo

Abstract

Background: lead poisoning can have a negative impact on the neuropsychological functions, including language, due to the damage it causes to the development of the Central Nervous System. Aim: to verify the occurrence of language disorders in children who suffered from led poisoning and to verify the correlation between the lead concentration level in the blood and the language disorders presented by the children. Method: language evaluation of 20 preschoolers, with lead concentration level in the blood above 10µg/dl. Results: 13 children presented language impairment involving only phonology or more than one language subsystem. The statistical analysis indicated that no correlation exists between the severity of the language impairment and the concentration levels of lead. Conclusion: the number of children with language impairment indicates lead poisoning as a risk factor for the present alterations, even though other risk factors for language disorders were found and the absence of correlation between the investigated variables.

Blood lead levels and longitudinal language outcomes in children from 4 to 12 years

“…Although few studies have specifically examined children with language impairment for EBL, work by Gahyva, Crenitte, Galdana, & Hage in 2008 pointed clearly to the multifactored involvement of environmental and genetic factors in language impairment. In their sample of 20 preschoolers with blood lead levels > 10μg/dL, 65% (n=13) of the children had language impairments including phonology and other language domains (Gahyva, Crenitte, Caldana, & Hage, 2008). Interestingly, a correlation was not found between the severity of language impairment and the degree of EBL.…”

Manejo Da Ferida De Pleurostomia Aberta E as Limitações Sociais Dos Pacientes No Pós-Operatório

“…Segundo Mazoto et al, (2014), quanto maior a proximidade do local contaminado, maior a contaminação pelo chumbo. Quatro, dos seis estudos analisados (JORGE, 2008;GAHYVA, 2008;RODRIGUES, 2007;RODRIGUES, 2009), foram realizados com crianças entre 1 e 6 anos e encontraram defasagens na área de linguagem. É sabido que nos primeiros anos de vida ocorre a maturação do sistema nervoso com subsequente desenvolvimento de habilidades auditivas e de linguagem (FRIEDERICI, 2006).…”

Processamento temporal, fonologia e escrita em crianças contaminadas por chumbo

“…A study that assessed 20 children with lead poisoning, aged three to six years, found immediate memory alteration in 65% of children 35 . When assessing 25 school-age children (six to thirteen years) through the Academic Performance Test, one study found better performance children not contaminated by lead and worse performance in children with lead poisoning 36 .…”
