AB  - The aim of our study was to assess the outcome of treatment of horizontal canal benign paroxysmal positional vertigo and to analyze the influence of the different prognostic factors on treatment failure. Fifty-nine patients with horizontal canal benign paroxysmal positional vertigo were included in the study. They were divided into two groups according to the treatment protocol, randomly. The first group, after treatment with the barbecue maneuver or inverted Gufoni, depending on the nystagmus form, was instructed to sleep on the side with weaker nystagmus, and the second group did not. In the first group, 88.9% of patients were cured and 91.3% in the second one. There was no significant difference between the two groups. Migraine and the apogeotropic form of nystagmus had a significant effect on treatment outcome, while other variables had no effect.

AB  - Background/Aim. A school teacher's occupation is one of the most vocal demanding professions. Vocal tiredness affects acoustic characteristics of voice, leads to the change in acoustic quality during vocal production. The aim of this study was to examine the influence of vocal tiredness on voice acoustic characteristics of school teachers. Methods. The study included 36 school teachers (16 male and 20 female) of 27-58 years of age. Vocal tiredness was evaluated by analyzing acoustic parameters of voice, using computerized laboratory "Kay Elemetrics". The voices were recorded before the first class on the beginning of a working week and after the last class at the end of a working week. Signal, noise and tremor parameters were processed. In their analysis the methods of descriptive statistics, as well as the analytical statistics (Student's t-test for paired samples, chi(2) test, Mann Whitney U-test and Pearson's correlation coefficient) were applied. Results. The obtained results showed statistically significant differences in average values of parameters as a consequence of the vocal tiredness (p  lt  0.01), while gender, age and being smoker or not, did not have a significant effect on voice acoustic characteristics in this group of examinees (p > 0.05). Conclusion. The results of the study suggest a casual relationship between vocal tiredness and voice quality in vocal professionals.

AB  - Objectives. The aim of the investigation was to obtain acoustic correlates of the vocal quality of patients with vocal polyps, before and after the endolaryngeal phonomicrosurgery (EPM). Methods. Acoustic voice tests were carried out on 46 female patients with vocal fold polyp, before the EPM intervention and 3 weeks after its completion. Acoustic voice parameters were compared with the control group without voice pathology. The results of the investigation were analyzed acoustically. Results. The results showed that jitter (%), shimmer (%), fundamental frequency variation (vF(0)), voice turbulence index (VTI), pitch perturbation quotient (PPQ), amplitude perturbation quotient (APQ), and NHR values significantly differentiate the patients with vocal fold polyps from a control group without any pathological changes in the larynx. All of the analyzed parameters improved significantly (P lt 0.05) after the phonomicrosurgical intervention and tended to reach normal values. Conclusions. The acoustic voice analysis may be used for presurgical and postsurgical voice-status evaluation.

AB  - Background/Aim. Prevention of the consequences of hearing loss can be accomplished by early hearing screening of the cochlear function in newborus, but also with continuous hearing screening in the early childhood. The aim of this study was to investigate the reliability and feasibility of otoacoustic emissions (OAE) in hearing screening in children, evaluate the frequency and type of hearing loss and determine etiological factors of these losses. Methods. In the study, 133 children, aged 2 to 7.5 years, were tested on both ears with transient evoked otoacoustic emissions (TEOAE) and distortion-product otoacoustic emissions (DPOAE). Before screening tests all children had undergone otoscopic examination. If children had not passed either or both hearing screening tests and/or abnormal otoscopic findings in at least one ear, audiological evaluation was scheduled to confirm or exclude hearing loss. Results. Eighty-five percent of children passed the hearing and otoscopic screening bilaterally. For additional audiologic tests 15% of children were referred. Agreement between otoscopic examination and screening tests was very good (agreement for TEOAE 95%, for DPOAE 93%). The results showed that normal tympanograms were very likely to be associated with normal screening tests. Sensitivity of TEOAE test was 94.12%, specificity 78.95%, while DPOAE sensitivity was 87.50% and specificity 75%. Hearing loss was found in 6.76% of the cases, conductive in 6.01% and sensorineural in 0.75%. Conductive hearing loss was a consequence of chronic otitis media with effusion in 25% of the cases, and a consequence of adhesive process in the middle ear in 8.33% of cases. Sensorineural hearing loss was a consequence of using ototoxic medications. Conclusion. TEOAE and/or DPOAE tests are reliable, noninvasive, and feasible methods for hearing screening in childhood.

AB  - Over the last several decades, cochlear implantation has been fully proven as the treatment for profound hearing losses. The direct electrical stimulation of the spiral ganglion hair cells through the electrode inserted in the cochlear scala tympani is the essence of the cochlear implant (CI) functioning. Modern technological development has introduced unexpected technical quality possibilities of the device itself, as well as coding strategies, which further enable improved patients' rehabilitation results. Nevertheless, in spite of cochlear implantation becoming a routine surgical procedure, which has been changing lives of thousands of profoundly deaf adults and children, it has possible complications. Though rare, these complications could lead to severe, even fatal consequences. Bacterial meningitis represents one of the most severe postoperative complications. In this article, our five-year experience with cochlear implantation is shown, compared to other, much bigger, experiences. Despite severity and a potentially fatal outcome of meningitis, it has rarely been seen, and the precise connection between surgical procedure and this complication is not yet clear. Do cochlear implants increase the risk of bacterial meningitis? Are deafness-associated factors predisposing the bacterial meningitis occurrence, independently from the implant? These are the questions that the Centers for Disease Control and Prevention (CDC), the Food and Drug Administration (FDA) and the CI surgeons have been facing, as well as manufacturers and patients with their families.

AB  - Introduction There are subjective and objective ways to examine the effects of vocal therapy in voice disorders. The most precise and objective check-up is the use of computer voice analysis. Objective The aim of the research was to perform a detailed analysis of acoustic structure of the vowel A before and after voice treatment in patients with vocal fold nodules in order to obtain objective verification of the vocal rehabilitation success. Methods We examined 30 female patients, aged 34.6 +/- 6.69 years, with vocal fold nodules. Acoustic parameters of voice were compared with the control group consisting of 21 subjects without voice pathology. In all persons the vowel A was recorded and analyzed before and after a month of vocal therapy. The success of the vocal therapy was tracked using computer analysis of vocal structure. Signal, noise and tremor parameters were processed. Results Of the analyzed vowel A parameters: STD, PER, JITA, JITT, RAP, vFO, ShdB, SHIM, APQ, VTI, SPI, F0, NHR, FTRI, eleven improved (p  lt  0.05 and p  lt  0.01). Three parameters (F0, NHR, FTRI) changed showing improvement, but the obtained differences were not statistically significant (p > 0.05). Conclusion Based on the obtained results it was concluded that vocal therapy gave satisfactory results, but that it should be continually applied until full stabilization of the voice.
