[Neurodevelopment of full-term small-for-gestational age infants in the second month of life].

The objective of the present study was to assess and to compare the neurodevelopment of full-term adequate (AGA) or small-for-gestational age (SGA) infants in the second month of life. Sixty-seven infants were evaluated: 43 AGA and 24 SGA, making use of the Bayley Scales of Infant Development. The SGA group Index Score (IS) was significantly lower in Mental and Motor Scales. Considering the body proportionality (Asymmetric, Symmetric-SGA and Control group) there was difference in Motor Scale (p=0.003) with lower scores in the Symmetric-SGA group. Comparing to the Control group IS percentiles, in Mental Scale there was difference between Asymmetric X Symmetric-SGA; in Motor Scale, there was difference between the Asymmetric X Control (p=0.039) and Symmetric-SGA X Control (p=0.007) groups; there was no difference between Asymmetric and Symmetric-SGA although both exhibited lower scores than the Control group.

Visual function and fine-motor control in small-for-gestational age infants.

OBJECTIVE: To compare visual function and fine-motor control of full-term infants small-for-gestational age (SGA) and appropriate for gestational age (AGA), in the first three months. METHOD: We evaluated prospectively 31 infants in the 1st month; 33 in the 2nd and 34 infants in the 3rd month, categorized as full-term; birth weight less than 10th percentile for SGA and 25th to 90th percentile for the AGA group. Genetic syndromes, infections, multiple congenital malformations were excluded. The Bayley Scales of Infant Development-II were used, especially items related to visual function and to fine-motor control outcomes. RESULTS: The Motor Index Score (IS) was significantly lower in the SGA group in the 2nd month. The items "attempts to bring hands to mouth", in the 1st month and "reaches for suspended ring", in the 3rd month showed higher frequency in the SGA group. CONCLUSION: The Motor IS was lower in the 2nd month and items of fine-motor control in the 1st month and in the 3rd month showed higher frequency in the SGA group.

[Neonatal Doppler velocimetry in full term small-for-gestational age newborns].

This study aimed to evaluate the cerebral blood flow of full term small-for-gestational age newborns, using cranial ultrasound Doppler at birth. This study was performed at CAISM/UNICAMP (Tertiary Health Center for Women). Sixty term newborns were selected and divided in two groups: appropriate-for-gestational age (AGA) (36 neonates) and small-for-gestational age (SGA) (24 neonates). Cranial ultrasound Doppler evaluation was performed on both groups, between 24 and 48 hours after birth. Cerebral blood flow velocity (CBFV) was lower in the small-for-gestational age group, in the anterior cerebral artery (ACA). Doppler measurements were different statistically between the groups only for values related to peak systolic flow velocity (PSFV) and mean flow velocity (MFV) in the ACA. There was no significant difference for any evaluated parameters of flow velocity in the middle cerebral artery (MCA). It was concluded that SGA newborns showed PSFV and MFV significantly reduced only in the ACA. Weight/gestational age, neonatal polycythemia and mean arterial blood pressure values were statistically related to MFV in the ACA. In presence of fetal suffering, mean arterial blood pressure values and smoking in the pregnancy were statistically related to MFV in the MCA.
