Full textThe genetic approach of inherited forms of deafness has been particularly effective for deciphering the molecular physiology of the cochlea. In contrast, this genetic dissection has so far provided little information about the central auditory system. The hypothesis of my laboratory is that part of the central hearing defects in genetic forms of deafness would be concealed due to cochlear damages, which deprive the auditory brain of all or part of the acoustic information it receives. The objective of my thesis was to characterize these masked central and peripheric deficits in a new mutant mouse model for Otogl, a genetic form of deafness. Mutations in Otogl cause peripheral deafness but are also associated to a susceptibility to audiogenic seizures, reflex seizures induced by a loud sound. In the cochlea, otogl is involved in the cohesion of the hair bundle, the mechanical antenna to the sound of sensory cells and in the tectorial membrane. My results showed that Otogl is expressed in the fibers of the primary auditory nerve and in additional structures of the cochlea, unveiling new roles for Otogl in the cochlea and the central auditory pathways. I also uncovered functional deficits in sound processing in heterozygous Otogl+/- mice that did not have peripheral hearing loss. Otogl therefore has a retrocochlear role in addition to its role in the cochlea. These results involve a particular category of auditory nerve fibers, the high-threshold fibers. Otogl mutant mice are a new model for studying high-threshold fibers and their role in the occurrence of audiogenic seizures in mice

Full textIntroduction: High frequency audiometry may contribute to the early detection of hearing loss caused by ototoxic medications. In the treatment of patients with cystic fibrosis, there are many ototoxic drugs that are widely used. Early detection of hearing loss should allow them to be identified before the damage reaches frequencies of speech. The damage caused by ototoxicity is irreversible, bringing important social and psychological consequences. In children, hearing loss, even restricted to high frequencies, can affect language development. Objective: Investigate the efficacy and effectiveness of hearing monitoring by high frequency audiometry in pediatric patients with cystic fibrosis. Methods: Electronic databases were searched PubMed, MEDLINE, Web of Science and LILACS, from January to November 2015 were consulted. We selected only the studies that was carried out high-frequency audiometry in patients with cystic fibrosis and treatment with ototoxic drugs, published in Portuguese, English and Spanish. For the evaluation of the methodological quality of the items we chose to use the GRADE system. Results: In the search process carried out from January to November 2015 were found 512 publications, and 250 of PubMed, MedLine 118, 142 Web of Science and 2 from LILACS. Of these, nine articles were selected. Conclusion: It was identified the occurrence of hearing loss in high frequencies, in cystic fibrosis patients without hearing complaints. It is assumed that high frequency audiometry may be an early diagnostic method to be recommended for hearing investigation of patients at risk for ototoxicity.

Full textIntroduction: the treatment of patients with cystic fibrosis involves the use of ototoxic drugs, and the most frequently used are the aminoglycoside antibiotics. Due to the frequent use of this drug, cystic fibrosis patients are at risk to develop hearing loss. Objective: the aim of this study was to evaluate the hearing of patients with cystic fibrosis by high frequency audiometry (HFA) and distortion product otoacoustic emissions (DPOAE). Patients and methods: retrospective and prospective crosssectional study including 75 individuals, 39 of the study group and 36 in the control group. HFA (250 – 16,000 Hz) and DPOAE tests were conducted. Results: the study group had thresholds significantly higher in the HFA in 250, 1,000, 8,000, 9,000, 10,000, 12,500 and 16,000 Hz (p=0.004) and higher prevalence of abnormal DPOAE at 1,000 and 6,000 Hz (p=0.001), with significantly lower amplitudes of 1,000, 1,400 and 6,000 Hz. There was a significant association between changes in hearing thresholds in HFA with the number of courses of aminoglycosides performed (p=0.005). Eighty-three percent of patients who completed more than 10 courses of aminoglycosides had hearing loss in HFA. Conclusion: a significant number of patients with cystic fibrosis who received repeated courses of aminoglycosides showed alterations in HFA and DPOAE.

Full textObjective: Assess the hearing thresholds through ultra-high frequency (UHF) audiometry for early detection of asymptomatic hearing alterations among patients with Cystic Fibrosis (CF). Material and methods: Sixty nine subjects having a mean age from 7 to 20 years, where 35 belong to the group study SG -diagnosed with CF and 34 to the control group CG - not diagnosed with CF - participated in a cross - sectional, case-control type study. Conventional tonal audiometric (250 Hz to 8.000 Hz) and ultra-high frequency audiometric (9.000 Hz a 16.000 Hz) tests were conducted, comparing the hearing thresholds between GS and CC. Descend technique using Unity PC-Siemens audiometer, HDA 200 phones, calibration according to ANSI s 3.6-1989 rule, imitanciometry using AZ26 Interacoustics equipment. Results: Sixty nine subjects having a mean age of 12,6 (± 3,65) were evaluated. The variable age and sex between GS and CG and the hearing assessment between the intra-group ears presented no statistically significant difference. The ears were analyzed through the average in each frequency due to lack of significantly differences between them. There was statistically significant difference in the hearing threshold in the 2.000 Hz (p = 0,049) and 8.000 Hz (p = 0,006) frequencies and in the ultra-high frequencies of 10.000 Hz (p = 0,004) and 16.000 Hz (p < 0,001) between GS and CG - higher in GC. Analyzing the frequencies in the GS by conventional audiometry, the 6.000 Hz and 8.000 Hz frequencies presented lowered hearing thresholds and in the CG, the most lowered threshold was at 6.000 HZ. In ultra-high frequencies in GS, the 14000 Hz frequency presented the lowest threshold. In GC the frequencies between 9.000 and 11.200 presented even lowered threshold. Conclusion: The increase of the thresholds from 6.000 Hz on, the statistically significant difference in 8.000, 10.000 and 16.000 Hz between GS and CG and the greater number of patients of GS presenting alterations in UHF only, suggest that the evaluation of these frequencies as a diagnostic and monitoring instrument of hearing alterations in patients undertaking treatment with potentially ototoxic drugs. The audiometry in UHF appears to early identify hearing damage in the hearing system of the group diagnosed with CF but still asymptomatic.

Full textThe vestibulocochlear (VIIIth cranial nerve) nerve of guinea pigs have special features not common for peripheral nerves in general. There are no detailed reports on the morphometric characteristics of the VIII nerve in adult guinea pigs. This is a descriptive and qualitative study that shows normal parameters that are useful in experimental models of the VIIIth nerve neuropathy. Eight adult guinea pigs were perfused with 2.5% glutaraldehyde in isotonic cacodilate buffer (0.025M). The right (N=4) and left (N=2) nerves were dissected in the median region, post-fixed in 1% osmuin tetroxide and embedded in epoxy resin. Semithin (0.5 µm) serial transverse sections were stained with 1% toluidine blue for light microscopy study. The descriptive histology and the topographical and histometric aspects of the median region of the nerve were analyzed, including myelinated fiber density, myelinated fiber diameter distribution, g ratio and number of endoneural capillary vessels. The cochlear nerve is enveloped by the vestibular nerve when they join together. Both, the cochlear and the vestibular nerves join to form the vestibulocochlear nerve with a Y shape, with approximately 5 mm in length. The nerve is widely vascularized and presents a complete mixture of the vestibular and cochlear myelinated fibers when the VIII nerve fascicle is constituted. The myelinated fibers are longitudinally oriented and present few endoneural connective tissue in between. No unmyelinated fibers were evidenced in the VIII nerve. The myelinated fiber diameter distribution was unimodal, with a peak at 3.5, and intervals between 1,5 and 6 m. The average number of fibers was 5.390 ± 1.504. The myelinated axon diameter distribution was also unimodal, with a peak at 2.5 µm of diameter were predominant quantitatively: 6.757 ± 1.922, and intervals between 1 and 4.5 µm. The average myelinated fiber density was 41.474 ± 4384 mm2, spread in a fascicular diameter of 0.77 ± 0.04 mm. The g ratio values varied from 0.2 to 0.9 and most of the myelinated fibers showed g ratio values of 0.7. Our results are original and only few parameters studied here were described in the literature. The vestibulocochlear nerve of the guinea pigs is a special afferent nerve, differing from other peripheral nerves (sensitive and motor) in its main anatomic and physiological characteristics, compared to other nerves from mammals. The adult guinea pig is an excellent model for the vestibulocochlear nerve neuropathy studies once it is similar to the human nerve.
