Isolated CHDs and neurodevelopmental follow-up using the Bayley Scales of Infant and Toddler Development and the Ages and Stages Questionnaire at 18 and 36 months.

Objectives: To compare early neurocognitive development in children born with and without isolated CHD using the Bayley Scales of Infant and Toddler Development (3rd edition) and the Ages and Stages Questionnaire (3rd edition).

Methods: Recruitment took place before birth. Women expecting fetuses with and without CHD causing disturbances in the flow of oxygenated blood to the fetal brain were included in a prospective cohort study comprising fetal MRI (previously published) and neurodevelopmental follow-up.

Childhood psychosis and urinary excretion of peptides and protein-associated peptide complexes.

Twenty-four infantile autistic children were compared with 12 children with other kinds of childhood psychoses, 5 children with so-called minimal brain dysfunction syndrome, 5 children with attention deficit disorder, 14 children with mental retardation, and 19 normal children with regard to chromatographic profiles of urinary products that give ultraviolet absorbency at 280 nm. Six main types of chromatographic patterns emerged. Fifty-four percent of the autistic children and 17% of the children with other psychoses showed a distinct pattern that was not seen in any other cases.
