Infection with Zika virus (ZIKV), a mosquito-borne flavivirus has been casually linked with increased congenital microcephaly in Brazil from 2015 through 2016. Sensitive and specific diagnosis of patients with Zika fever (ZIKF) remains critical for patient management. We developed a ZIKV NS5 qRT-PCR assay by combining primers described by Balm et al. and a new Taqman probe. The assay was evaluated and compared with another assay described by Lanciotti et al. (ZIKV 1107) using 51 blood and 42 urine samples from 54 suspected ZIKV patients. ZIKV NS5 performed better in terms of sensitivity with more samples detected as ZIKV-positive (n = 37) than ZIKV 1107 (n = 34) for urine, and ZIKV-positive (n = 29) than ZIKV 1107 (n = 26) for blood. Both assays displayed good overall agreement for urine (κappa = 0.770) and blood (κappa = 0.825) samples. Improved availability of validated diagnostic tests, such ZIKV NS5 qRT-PCR, will be critical to ensure adequate and accurate ZIKV diagnosis.

BackgroundUnidentified hearing loss at birth can badly affect the linguistic, social, and educational development of children. National and international committees on infant hearing emphasize the importance of early identification of hearing loss, with follow-up and early intervention. The aim of this study was to analyze data on hearing development from a program following up exits from the Neonatal Intensive Care Unit (NICU) and from neonatal intermediate care wards in Prof. Dr. Jose Aristodemo Pinotti Women’s Hospital in the Brazilian State of Sao Paulo.Material and MethodsThis was a retrospective study based on records from a follow-up program. Data came from records collected from 2012 to 2015 on 88 subjects, and included the results of behavioral hearing tests, visual reinforcement audiometry and tympanometry. The data were descriptively and statistically analyzed.ResultsChanges in the development of hearing abilities over the first two years of life in children that stayed a...

BackgroundAuditory brainstem response (ABR) potential is important for audiological diagnosis, reflecting the integrity of the structures of the auditory system up to the brainstem. The click stimulus is the best known and is most used in clinical practice. However, different devices and examiners may yield distinct results, and each institution tends to use its own parameters. We aimed to analyze the latency values of wave I, III, V, and interpeak intervals I–III, III–V, I–V values obtained in assessing ABR using a new device.Material/MethodsWe performed a cross-sectional study of 73 participants with normal hearing thresholds and no hearing problems. All underwent basic audiological (air and bone conduction, Speech Recognition Threshold, Speech Recognition Index, acoustic reflex, and tympanometry) and electrophysiological evaluation (ABR assessment).ResultsAbsolute latency and interpeak values from ABR showed earlier responses in women, faster than international standards suggest. The responses were similar to other studies carried out previously, with the exception of wave I values, which were a little earlier in females.ConclusionsWe assessed normative data from measurement of latency values of wave I, III, V, and interpeak intervals I–III, III–V, and I–V applying 2 standard deviations in the assessment of ABR using the new Neuro-Audio/ABR device created by Neurosoft.

Introduction: Auditory processing depends on afferent and efferent auditory pathways integrity. Most of the studies designed to investigate the efferent system focused on the suppression of the otoacoustic emissions. However, the neural mechanisms underlying efferent activity on higher regions, such as thalamus and cortex, are still not well known. Objectives: To analyze the suppression effect of the cognitive auditory evoked potential in children with normal hearing. Methods: Eighteen children aged 8 to 13 years participated in the study. All the participants had pure-tone threshold below 20 dBHL for octaves from 250 to 8,000 Hz, “A”-type tympanogram with the presence of ipsilateral and contralateral acoustic reflexes, functional integrity of auditory pathways assessed by ABR, and no neurological disorders. P300 was recorded at 70 dBHL. The stimulus presented was tone burst at the frequency of 2 kHz for the infrequent stimulus and 1 kHz for the frequent one. The equipment used was a Biologic Navigator Pro and the test was repeated using contralateral white noise stimulus of 70 dBHL. Results: The studied children showed significantly longer P300 latencies at the presence of white noise contralateral stimulation. Amplitude mean values reduced with white noise, but there was no statistical significance. Conclusion: These results suggest a possible influence of the auditory efferent system over the P300 responses when contralateral white noise stimulation is used, causing longer wave latencies. New studies should be conducted for a better understanding of these results and for improving the use of this procedure in clinical researches. Keywords: hearing, auditory evoked potentials, electrophysiology.

Electrophysiology is an objective evaluation method that allows investigating the responses of the central auditory nervous system arising from the capture of neuronal responses through surface electrodes. In addition to the possibility of investigating and diagnosing different pathologies, electrophysiology proves to be an effective and effective instrument in monitoring auditory intervention programs. Auditory rehabilitation programs is based on the premise of neuroplasticity that derives from a capacity for neuronal change due to intense sound stimulation, specific and directed to the patient’s needs. Throughout this chapter, current studies that correlate electrophysiology with auditory training programs in different clinical populations will be presented, such as: hearing in typically developed individuals, hearing and school difficulties, hearing and CAPD, hearing and otitis media, hearing and hearing loss, and hearing and voice. Electrophysiological tests are important object...

Introduction: Otoacoustic emissions (OAEs) evaluate the functional status of the cochlea. Repeated otitis media (OM) can cause changes in the peripheral structures of the auditory system, and, in this way, middle ear infection may irreversibly damage the middle ear, or even the cochlea. Objectives: To analyze the results of transiently evoked otoacoustic emissions (TEOAEs) and distortion product otoacoustic emissions (DPOAEs) in individuals with a history of OM. Method: Participants with 8 to 16 years of schooling were split into two groups: a control group (CG) of 50 subjects who had no history of otological disease and an experimental group (EG) of 50 subjects who had a history of recurrent otitis in childhood and had consequently undergone myringotomy to insert bilateral ventilation tubes. All children underwent basic audiological assessment (tonal audiometry, speech audiometry, and immittance testing) and otoacoustic emission testing (TEOAEs and DPOAEs). Results: There were no s...

ABSTRACTZika virus (ZIKV) has the ability to cross placental and brain barriers, causing congenital malformations in neonates and neurological disorders in adults. However, the pathogenic mechanisms of ZIKV-induced neurological complications in adults and congenital malformations remain unknown. Gas6 is a soluble TAM receptor ligand able to promote flavivirus internalization and downregulation of immune responses. Here we demonstrate high Gas6 levels in the serum of patients with neurological complications which correlated with downregulation of genes associated with the type I IFN responses as consequence of Socs1 upregulation. Gas6 gamma-carboxylation is essential for ZIKV replication in monocytes, the main source of this protein. Gas6 also facilitates ZIKV replication in adult immunocompetent mice enabled susceptibility to transplacental infection and congenital malformations. Our data thus indicate that ZIKV promotes the upregulation of its ligand Gas6, which contributes to vira...

The aim of this study was to assess the parameters of choice, such as duration, intensity, rate, polarity, number of sweeps, window length, stimulated ear, fundamental frequency, first formant, and second formant, from previously published speech ABR studies. To identify candidate articles, five databases were assessed using the following keyword descriptors: speech ABR, ABR-speech, speech auditory brainstem response, auditory evoked potential to speech, speech-evoked brainstem response, and complex sounds. The search identified 1288 articles published between 2005 and 2015. After filtering the total number of papers according to the inclusion and exclusion criteria, 21 studies were selected. Analyzing the protocol details used in 21 studies suggested that there is no consensus to date on a speech-ABR protocol and that the parameters of analysis used are quite variable between studies. This inhibits the wider generalization and extrapolation of data across languages and studies.
