- Auditory pathway maturational study in small for gestational age preterm infants(2014) ANGRISANI, Rosanna Giaffredo; DINIZ, Edna Maria Albuquerque; GUINSBURG, Ruth; FERRARO, Alexandre Archanjo; AZEVEDO, Marisa Frasson de; MATAS, Carla GentilePURPOSE: To follow up the maturation of the auditory pathway in preterm infants small for gestational age (SGA), through the study of absolute and interpeak latencies of auditory brainstem response (ABR) in the first six months of age. METHODS: This multicentric prospective cross-sectional and longitudinal study assessed 76 newborn infants, 35 SGA and 41 appropriate for gestational age (AGA), born between 33 and 36 weeks in the first evaluation. The ABR was carried out in three moments (neonatal period, three months and six months). Twenty-nine SGA and 33 AGA (62 infants), between 51 and 54 weeks (corrected age), returned for the second evaluation. In the third evaluation, 49 infants (23 SGA and 26 AGA), with age range from 63 to 65 weeks (corrected age), were assessed. The bilateral presence of Transient Evoked Otoacoustic Emissions and normal tympanogram were inclusion criteria. RESULTS: It was found interaural symmetry in both groups. The comparison between the two groups throughout the three periods studied showed no significant differences in the ABR parameters, except for the latencies of wave III in the period between three and six months. As for the maturation with tone burst 0.5 and 1 kHz, it was found that the groups did not differ. CONCLUSION: The findings suggest that, in the premature infants, the maturational process of the auditory pathway occurs in a similar rate for SGA and AGA. These results also suggest that prematurity is a more relevant factor for the maturation of the auditory pathway than birth weight.
- Caracterização eletrofisiológica da audição em prematuros nascidos pequenos para a idade gestacional(2013) ANGRISANI, Rosanna Mariangela Giaffredo; AZEVEDO, Marisa Frasson de; CARVALLO, Renata Mota Mamede; DINIZ, Edna Maria de Albuquerque; FERRARO, Alexandre Archanjo; GUINSBURG, Ruth; MATAS, Carla GentilePURPOSE: To characterize the Auditory Brainstem Response (ABR) of small for gestational age preterm newborns and to compare the findings to those of appropriate for gestational age premature newborns in order to verify whether the small for gestational age condition is a risk factor for hearing loss. METHODS: This prospective cross-sectional multicenter study evaluated 72 preterm newborns of both genders (35 small and 37 appropriate for gestational age), who were born at 30 to 36 weeks of gestational age and were evaluated before hospital discharge. Only newborns with present transient evoked otoacoustic emissions and tympanometry type A were included. The ABR was performed with click stimuli. The quantitative data analysis was performed using mean and standard deviation measures for each group. For qualitative analysis, the ABR results were classified as normal or altered according to the absolute latencies of waves I, III, V and interpeaks I-III, III-V, I-V. The analysis was carried out considering the age of the newborn at the time of examination. RESULTS: Alterations were evident in 32 newborns (44.44%), being 15 small (43%) and 17 appropriate for gestational age (46%), with no between-groups difference. Of the 15 small for gestational age newborns with altered ABR, six presented as auditory risk only the small for gestational age condition. In the group of adequate for gestational age newborns, there was a higher occurrence of alteration in males. CONCLUSION: There was no difference in responses of auditory evoked potential between small and appropriate for gestational age preterm newborns. Therefore, the condition does not behave as a risk factor for retrocochlear impairment.
- Desempenho linguístico de prematuros de 2 anos, considerando idade cronológica e idade corrigida(2016) MONTEIRO-LUPERI, Telma Iacovino; BEFI-LOPES, Debora Maria; DINIZ, Edna Maria Albuquerque; KREBS, Vera Lucia; CARVALHO, Werther Brunow deABSTRACT Introduction Preterm birth causes problems that are not restricted to perinatal mortality. Some premature, even in the absence of brain damage, have negative effects on various aspects of development, such as language difficulties. Objective This study aimed to verify the linguistic performance of preterm children at 2 years old, considering the chronological age and corrected age. Methods The study included 23 preterm children and applied the Test of Early Language Development- TELD-3 to assess the language skills. Results The premature children showed the linguistic performance alterations in Teld-3 in 39.13% of cases. They were also analyzed considering the delay to the chronological and corrected ages and there was no difference in performance for both receptive subtests (p = 0.250) and significant (p = 1.000). Conclusion The group of premature children at 2 years is a population at risk for language disorders that cannot be compensated with age correction.
- Longitudinal electrophysiological study of auditory pathway in small for gestational age infants(2014) ANGRISANI, Rosanna Giaffredo; DINIZ, Edna Maria Albuquerque; GUINSBURG, Ruth; FERRARO, Alexandre Archanjo; AZEVEDO, Marisa Frasson de; MATAS, Carla GentilePURPOSE: To follow the maturation of the auditory pathway of infants born small for gestational age term, by studying absolute and interpeak latencies of Auditory Brainstem Response (ABR) in the first six months of life. METHODS: Multicentric prospective longitudinal study. The ABR was carried out in the neonatal period in 96 newborn infants, 49 small for gestational age (SGA) and 47 appropriate for gestational age (AGA). Of these, 77 infants (39 SGA and 38 AGA) returned for a second evaluation. In the third evaluation, 70 infants (35 SGA and 35 AGA) returned. RESULTS: SGA and AGA did not present significant differences in the neonatal period and at three months of life. However, at six months, there was statistical significant difference between SGA and AGA groups for the latencies of wave III and interpeak I-III. Latencies of ABR waves decreased more rapidly in the first three months than the third to the sixth month of life for the SGA. AGA group showed progressive decrease in latency of ABR waves during the six months. CONCLUSION: The findings suggest that, for SGA infants, the maturational process of the auditory pathway occurs in different rate when compared to AGA infants. The SGA infants have faster maturation especially at the first three months of life, while in infants AGA, this process occurred in a constant and gradual way throughout the six months studied.
