Acompanhamento de crianças prematuras com alto risco para alterações do crescimento e desenvolvimento: uma abordagem multiprofissional

Objetivo: Descrever a atividade do ambulatorio multiprofissional formado por neonatologista e fisiatra, fisioterapeuta, terapeuta ocupacional, fonoaudiologas e psicologa que realizaram avaliacoes aos 3, 6, 9, 12, 18 e 24 meses de idade corrigida. Metodos: Foram realizadas avaliacoes multiprofissionais pela equipe, incluindo avaliacao pela escala de desenvolvimento Bayley III. A amostra foi constituida por 20 criancas nascidas em hospital de nivel terciario em Sao Paulo, Brasil, com peso inferior a 1250 g ou idade gestacional abaixo de 32 semanas no periodo de Abril de 2006 a Abril de 2007. Resultados: A idade gestacional media ao nascimento foi de 28.8 semanas, peso medio 1055 g, tempo de internacao medio de 46,3 dias, e idade materna media de 35 anos. Observou-se que 15% das criancas apresentaram alteracoes sensorio-motoras, 20% alteracoes no desenvolvimento auditivo e 10% alteracoes motoras. Pela aplicacao da Bayley III, observou-se 10% dos casos com alteracao na area de comunicacao e 10% com alteracao na area motora. Os pais foram orientados a estimularem a crianca ou foi sugerida intervencao especifica. Observou-se que entre 6 e 18 meses de idade corrigida houve maior ocorrencia de atrasos do desenvolvimento, que se adequou aos 24 meses. Conclusoes: A maioria das criancas avaliadas alcancou crescimento e desenvolvimento adequado aos 24 meses de idade corrigida. Recomendam-se estudos futuros com amostra ampliada, assim como a possibilidade de um acompanhamento dessa populacao ate o periodo de alfabetizacao.

Comparação da influência entre tempos de polimerização em resinas compostas polimerizadas com led e luz incandescente

The purpose of this work was to compare polymeric dental resins cured with halogen lamp and with light emission diode (LED) devices, using the grinding disk method customized for dentistry and the corresponding microhardness values. Tests were carried out on resin samples of five brands, which were cured for 10, 20 and 40 s with the two devices. The analysis of microhardness and aggressiveness has allowed us to conclude that there is no correlation between these properties. In Microhardness tests, the material heterogeneity has produced relative high standard deviation values and has not shown statistical differences between the analyzed samples. In the statistical analysis for the results with the grinding disk method, the resin with highest wear was the Tetric Ceram, cured with LED device for 10 s (aggressiveness average 0.170 mm3/N.m ). The composite resin with least wear was Charisma, cured with halogen lamp device for 20 s (aggressiveness average 0.057 mm3/N.m ).

Follow-up of premature children with high risk for growth and development delay: a multiprofessional assessment

OBJECTIVE To describe the activities of a multiprofessional outpatient clinic performed by neonatologist, physiatrist, physical therapist, occupational therapist, speech therapist, audiologist and psychologist, who evaluated the development of premature newborns. METHODS Twenty children born at a tertiary-care hospital (São Paulo, Brazil), between April 2006 and April 2007, with birth weight below 1250 g or less than 32 weeks of gestation, were evaluated. The multiprofessional evaluation included assessment of development using the Bayley III scale, at the corrected age of 3, 6, 9, 12, 18 and 24 months. RESULTS The mean gestation age at birth was 28.8 weeks; mean birth weight was 1055 g. The mean maternal age was 35 years and the mean length of stay of neonates was 46.3 days. Fifteen percent of children presented impaired sensory motor skills, 20% had hearing abnormalities and 10% motor alterations. Bayley III showed alterations in the communication area in 10% of subjects and in the motor area in 10% of individuals. The parents were oriented to stimulate the child or a specific intervention was suggested. The major development delay was observed between 6 and 18 months of age and the development was improved at 24 months of age. CONCLUSIONS Most children evaluated had improved growth and development at 24 corrected-age months. Further studies with a larger sample are recommended, as well as the possibility to follow this population group up till the primary school.

Effect of cervical relining of acrylic resin copings on the accuracy of stone dies obtained using a polyether impression material

The purpose of this study was to evaluate the accuracy of the respective dies after polyether elastomeric procedure in the presence or absence of cervical contact of the acrylic resin shell with the cervical region, establishing a comparison to dies obtained with stock trays. This study consisted of three groups with 10 specimens each: 1) acrylic copings without cervical contact, (cn); 2) acrylic copings with cervical contact (cc); 3) perforated stock tray, (st). The accuracy of the resulting dies was verified with the aid of a master crown, precisely fit to the master steel die. ANOVA test found statistically significant differences among groups (p<0.001). Tukeys test found that the smallest discrepancy occurred in group cn, followed by cc, while the st group presented the highest difference (cc x cn: p=0.007; st x cn: p<0.001; st x cc: p<0.001).
