Baroreceptors in preterm infants: their relationship to maturity and disease / Stephanie WALDMAN in Developmental Medicine & Child Neurology, 21-6 (December 1979)

Public ISBD [article]  inDevelopmental Medicine & Child Neurology > 21-6 (December 1979) . - p.714-722 Titre : Baroreceptors in preterm infants: their relationship to maturity and disease Type de document : Texte imprimé et/ou numérique Auteurs : Stephanie WALDMAN, Auteur ; Alfred N. KRAUSS, Auteur ; Peter A. M. AULD, Auteur Année de publication : 1979 Article en page(s) : p.714-722 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Using passive tipping to a 45 degrees head-up position, an attempt was made to elicit reflex vasoconstriction in 13 non-distressed preterm infants and 27 infants with hyaline membrane disease, all between 26 and 38 weeks gestation. An increase in vascular tone associated with a significant reduction in peripheral blood-flow was found in 11 of the 13 non-distressed infants, while the same response was lacking in 23 of the 27 distressed infants. No infant demonstrated significant tachycardia with tilting, and the non-distressed infants failed to maintain their mean aortic blood-pressure during tilting. The results suggest that reflex control of vascular tone is present in non-distressed infants as early as 26 weeks gestation, but not in infats with hyaline membrane disease, possibly because of a maximal increase in vascular tone as a response to illness. This is indicated by the findings of significantly higher resting peripheral vascular resistance and lower peripheral blood-flow in infants with this diesease.

Early predictors of neurodevelopmental outcome of very low-birthweight infants at three years / Gail ROSS in Developmental Medicine & Child Neurology, 28-2 (April 1986)

Public ISBD [article]  inDevelopmental Medicine & Child Neurology > 28-2 (April 1986) . - p.171-179 Titre : Early predictors of neurodevelopmental outcome of very low-birthweight infants at three years Type de document : Texte imprimé et/ou numérique Auteurs : Gail ROSS, Auteur ; Peter A. M. AULD, Auteur ; Evelyn LIPPER, Auteur Année de publication : 1986 Article en page(s) : p.171-179 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Seventy-nine premature infants weighting less than 1501 g at birth but appropriate for gestational age underwent a neurodevelopmental examination at one, three, six, nine and 12 months post-term, and a standard neurological examination and the Stanford-Binet Intelligence Scale at three to four years of age. Children were classified as normal, suspect or abnormal on the three-year neurological examination, on the IQ test, and on composite neurodevelopmental outcome at age three years. Results showed that items from both the nine- and 12-month neurodevelopmental examinations correctly classified about 80 per cent of the children as to composite outcome at three years. In addition, the 12-month examination enabled correct prediction for 89 per cent of the children as to neurological outcome and for 82 per cent as to IQ. Neurodevelopmental examination of high-risk infants in the last quarter of the first year of life (post-term) should assist pediatricians in predicting which children will be normal and which will require early intervention.

Hand preference of four-year-old children: its relationship to premature birth and neurodevelopmental outcome / Gail ROSS in Developmental Medicine & Child Neurology, 29-5 (October 1987)

Public ISBD [article]  inDevelopmental Medicine & Child Neurology > 29-5 (October 1987) . - p.615-623 Titre : Hand preference of four-year-old children: its relationship to premature birth and neurodevelopmental outcome Type de document : Texte imprimé et/ou numérique Auteurs : Gail ROSS, Auteur ; Peter A. M. AULD, Auteur ; Evelyn LIPPER, Auteur Année de publication : 1987 Article en page(s) : p.615-623 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Information was obtained at age four years on the hand preference of 98 children who had been born prematurely with a very low birthweight and of 54 children born at term with no birth complications. Data were also collected on the hand preference of their parents. The preterm children had been assessed at age three years for IQ, expressive language, speech articulation and neurological status. A significantly lower proportion of preterm than of term children used their right hand for unimanual activities. Furthermore, those preterm children who were not right-handed were significantly more likely to have lower IQs, expressive language delays and articulation problems. Among preterm children with IQs greater than or equal to 85, language and speech problems were no more likely to occur in those who preferred the left hand or who used both hands than in those who preferred the right. The findings of this study support the theory that birth complications lead to cerebral insult which may alter hand preference, and at the same time affect mental and motor development.
