Brainstem auditory-evoked responses among children afflicted by severely hypoxic CHD.

Main Aim: To electrophysiologically determine the impact of moderate to severe chronic hypoxia (H) resulting from a wide array of CHD (HCHD) conditions on the integrity of brainstem function.

Materials And Methods: Applying brainstem auditory-evoked response methodology, 30 chronically afflicted HCHD patients, who already had undergone heart surgery, were compared to 28 healthy control children (1-15 yo) matched by age, gender and socioeconomic condition. Blood oxygen saturation was clinically determined and again immediately before brainstem auditory-evoked response testing.

Iron therapy substantially restores qEEG maturational lag among iron-deficient anemic infants.

Objective: To use quantitative electroencephalography (qEEG) to assess the impact of iron-deficiency anemia on central nervous system maturation in the first year of life.

Method: Twenty-five infants (3-12 months old) presenting ferropenic anemia (IDA) and 25 healthy controls (CTL1), matched by age/gender with the former, were studied in two stages. Electroencephalogram during spontaneous sleep was recorded from all participants; the fast Fourier transform was calculated to obtain absolute power (AP) and relative power (RP) qEEG measures.

Leukocyte production of IFN-γ and TNF-α in 8- to 12-y-old children with low serum iron levels.

Objective: Iron deficiency is likely the most common nutritional deficiency worldwide; low iron concentrations have been related to alterations in immune system functions; therefore, the aim of this study was to determine the effect of low serum iron (LSI) concentrations on the production of proinflammatory cytokines by peripheral blood leukocytes in 8- to 12-y-old children from a local community.

Methods: We obtained 120 blood samples and determined full blood counts and serum iron concentrations. An LSI and a control group, paired by age and sex were established using serum iron <60 μg/dL as the cutoff point.

[Electroencephalographic and neurodevelopmental disorders in severe congenital heart disease: A follow-up study].

Congenital heart defects are the most common malformations at birth. Due to the fact that the developmental windows at early stages close rapidly, the aim of this study was to determine the impact of congenital heart defects on the central nervous system at short and medium terms after applying traditional and quantitative electroencephalography techniques and a test of neurodevelopment. Twenty-one patients (8-27 months, x = 14.

[Electroencephalographic and neurodevelopmental disorders in toddlers with severe congenital heart diseases. Preliminary study].

Unlabelled: Within the field of pediatric heart disease, congenital cardiopathology is the most important issue due to the fact that in these patients a delay of neurodevelopment is the most frequent morbidity. The major aim of this work was to determine the impact of severe congenital cardiopathology (SCC) on the central nervous system (CNS) through the study of the electroencephalogram (EEG) and the assessment of neurodevelopment.

Population And Methods: Children under 3 years old, 41 of them presenting SCC and 15 healthy controls (C) were studied.
