Abstract: Introduction: The effects of lead on children's health have been widely studied. Aim: To analyze the correlation between the long latency auditory evoked potential N2 and cognitive P3 with the level of lead poisoning in Brazilian children. Methods: This retrospective study evaluated 20 children ranging in age from 7 to 14 years at the time of audiological and electrophysiological evaluations. We performed periodic surveys of the lead concentration in the blood and basic audiological evaluations. Furthermore, we studied the auditory evoked potential long latency N2 and cognitive P3 by analyzing the absolute latency of the N2 and P3 potentials and the P3 amplitude recorded at Cz. At the time of audiological and electrophysiological evaluations, the average concentration of lead in the blood was less than 10 ug/dL. Results: In conventional audiologic evaluations, all children had hearing thresholds below 20 dBHL for the frequencies tested and normal tympanometry findings; the auditory evoked potential long latency N2 and cognitive P3 were present in 95% of children. No significant correlations were found between the blood lead concentration and latency (p = 0.821) or amplitude (p = 0.411) of the P3 potential. However, the latency of the N2 potential increased with the concentration of lead in the blood, with a significant correlation (p = 0.030). Conclusion: Among Brazilian children with low lead exposure, a significant correlation was found between blood lead levels and the average latency of the auditory evoked potential long latency N2; however, a significant correlation was not observed for the amplitude and latency of the cognitive potential P3.

Abstract: purpose: to evaluate the repeated measurements of the real ear unaided response (reur), real ear aided response (rear) and insertion gain (reig) conducted as face to face (f) and via telecounselling (t). method: longitudinal prospective study. four measures of reur, rear and reig (carried out with speech noise stimulus presented at 65 db spl at 0° azimuth) were obtained in 19 ears in normal hearing adults, face to face and via synchronous telecounsellings with remote control of the real ear equipment and interactive video. polycom pvx software was used for desktop sharing and video and audio transmission. the loca area network (lan) usp was used for the connection (transmission rate: 384 kbps). dahlberg’s casual errors were calculated for obtaining the measures for frequencies from 250 to 8000 hz. results: casual errors between f and t measures were very similar, being greater for frequencies above 4 khz. the differences between f and t measures were no greater than the variability reported for real ear measures. conclusion: probe microphone measures obtained via telecounselling provides reliable results and similar to those obtained by standard procedures.

Abstract: OBJETIVO: avaliar as medidas repetidas da resposta de ressonancia da orelha externa sem (REUR) e com uso de amplifica o (REAR) e o ganho de inser o (REIG), realizados face a face e via teleconsulta. MéTODO: estudo prospectivo longitudinal. Foram realizadas quatro repeti es da REUR, REAR e REIG (com estímulo speech noise apresentado em 65 dB NPS e 0o azimute) em 19 orelhas de adultos ouvintes normais, via face a face (F) e teleconsulta síncrona por controle remoto de aplicativo (T) e vídeo interativo. O software Polycom PVX foi utilizado para compartilhamento e transmiss o de áudio e vídeo. A conex o foi realizada via LAN (Local Area Network) USP na velocidade de 384 kbps Foi calculado o erro causal (Dalhberg) entre as quatro medidas para frequências de 250 a 8000 Hz. RESULTADOS: os erros casuais entre as medidas F e T foram muito semelhantes, sendo maiores nas frequências acima de 4 kHz. As diferen as e varia es entre as medidas F e T estavam dentro da magnitude de variabilidade do procedimento de medidas com microfone sonda. CONCLUS O: as medidas com microfone sonda via teleconsulta fornece resultados confiáveis e similares aos obtidos pelo procedimento padr o.

Abstract: Las cardiopatías congénitas tienen una incidencia de aproximadamente 1 de cada 100 recién nacidos. Alrededor de la mitad de los ni os afectados mueren durante el primer a o de vida si no se trata. El corazón univentricular es una de ellas, que se caracteriza por la presencia de solo una cavidad ventricular. El 80% de los pacientes,desde el punto de vista morfológico, presentan un ventrículo único semejante a la cavidad ventricular izquierda, separada de una cavidad infundibular de salida por un tabique bulboventricular. En esta anomalía la sangre venosa sistémica y pulmonar se mezcla en la cámara ventricular, dando como resultado la hipoxia general del paciente e insuficiencia cardíaca. Presentamos el caso clínico, de un infante de 6 meses de edad con presencia de esta cardiopatía y otras patologías asociadas a esta malformación congénita.
Dietary Supplementation with Lactobacilli Improves Emergency Granulopoiesis in Protein-Malnourished Mice and Enhances Respiratory Innate Immune Response
Matias Herrera, Susana Salva, Julio Villena, Natalia Barbieri, Gabriela Marranzino, Susana Alvarez
PLOS ONE , 2014, DOI: 10.1371/journal.pone.0090227
Abstract: This work studied the effect of protein malnutrition on the hemato-immune response to the respiratory challenge with Streptococcus pneumoniae and evaluated whether the dietary recovery with a probiotic strain has a beneficial effect in that response. Three important conclusions can be inferred from the results presented in this work: a) protein-malnutrition significantly impairs the emergency myelopoiesis induced by the generation of the innate immune response against pneumococcal infection; b) repletion of malnourished mice with treatments including nasally or orally administered Lactobacillus rhamnosus CRL1505 are able to significantly accelerate the recovery of granulopoiesis and improve innate immunity and; c) the immunological mechanisms involved in the protective effect of immunobiotics vary according to the route of administration. The study demonstrated that dietary recovery of malnourished mice with oral or nasal administration of L. rhamnosus CRL1505 improves emergency granulopoiesis and that CXCR4/CXCR12 signaling would be involved in this effect. Then, the results summarized here are a starting point for future research and open up broad prospects for future applications of probiotics in the recovery of immunocompromised malnourished hosts.
Effect of Audiovisual Training on Monaural Spatial Hearing in Horizontal Plane
Kuzma Strelnikov,Maxime Rosito,Pascal Barone
PLOS ONE , 2012, DOI: 10.1371/journal.pone.0018344
Abstract: The article aims to test the hypothesis that audiovisual integration can improve spatial hearing in monaural conditions when interaural difference cues are not available. We trained one group of subjects with an audiovisual task, where a flash was presented in parallel with the sound and another group in an auditory task, where only sound from different spatial locations was presented. To check whether the observed audiovisual effect was similar to feedback, the third group was trained using the visual feedback paradigm. Training sessions were administered once per day, for 5 days. The performance level in each group was compared for auditory only stimulation on the first and the last day of practice. Improvement after audiovisual training was several times higher than after auditory practice. The group trained with visual feedback demonstrated a different effect of training with the improvement smaller than the group with audiovisual training. We conclude that cross-modal facilitation is highly important to improve spatial hearing in monaural conditions and may be applied to the rehabilitation of patients with unilateral deafness and after unilateral cochlear implantation.

Abstract: Este texto apresenta a atividade Colcha de Retalhos para falar de vida, forma o e autoforma o, e o lugar e a importancia da educa o estética e bioética na forma o dos professores, através das histórias tecidas em retalhos, como possibilidade de o professor teorizar a partir da pesquisa de sua própria prática e a emergência da autoria.Tem-se aqui como referencial teórico Josso (2002), Freire (1992; 1997), Hillman (1995; 1997) e Ferreira-Santos (2004). O estudo aponta para a pedagogia imaginal como uma aquisi o de saber pela experiência imaginativa para pensar a forma o estética no campo das imagens e o lugar das metáforas nas autobiografias como frui o do imaginário. Palavras-chave: Forma o. História de vida. Imaginário.
