The voice sample of 75 subjects with various voice qualities from normal to severely dysphonic was evaluated by three expert evaluators twice by using both Kotby Modified GRBAS and Cape-V Scale for assessment of the efficiency of both scales for assessment of voice quality. The inter and intra ratter evaluation was done and acoustic and aerodynamic analysis was measured. There was excellent correlation between both overall modified GRBAS grade and for CAPE-V severity grade among total group and gender classification. The Interclass correlation coefficient was Good and ranging from 0.878 to 0.949 for both scales. There are highly significant correlation of between the subjective evaluation by using both scales with acoustic and aerodynamic analysis for jitter, shimmer, and noise to harmonic ratio for vowel and maximum phonation time. Both scales are reliable, valid for assessment of voice quality. Modified GRBAS is easer to present and Cape-V Scale is more sensitive for evaluation of minimal change.

Objective: This study was conducted with the purpose of analyzing the effects of hemodialysis on voice characteristics of patients with chronic renal failure. Design: A total of 66 patients were participated in the study, including 26 males and 40 females ranging in age from 19 to 68 years. Patients underwent evaluation of their voice directly before and after hemodialysis using computerized speech lab (CSL) (4300, Kay Elemetrics Corp.) and Aerophone II Model 6800 Kay Elemetrics Corp. The vocal acoustic parameters studied include average pitch, jitter, shimmer and noise-to-harmonic ratio. The aerodynamic parameters include vital capacity, maximum phonation time, phonation quotient, mean flow rate, sub glottic pressure and glottal efficiency. The data were analyzed using the paired t-test for the total sample, the male and female subgroups and also for the patient underwent ultrafiltration with hemodialysis. Results: In the total sample and in the female subgroup, there is a significant difference in phonation quotient after hemodialysis. The male subgroup showed no significant differences in all acoustic and aerodynamic parameters after hemodialysis. The group with positive ultrafiltration showed significant differences in both vital capacity and phonation quotient after hemodialysis. Conclusion: There was no effect of hemodialysis on acoustic characteristics of voice; however, there was a decrease in vital capacity and phonation quotient after hemodialysis especially with ultrafiltration. Recommendation: Further studies that include auditory perceptual assessment of voice and stroboscopic examination of the vocal folds may help in detecting subtle changes that may occur after hemodialysis.

Objective This study was conducted to investigate the effect of chronic renal failure (CRF) on acoustic and aerodynamic parameters of voice and to compare the results with a group of individuals with normal renal function. Design The participants in this study were divided into two groups. A clinical group (the patient group) consisted of 66 adults diagnosed as having CRF (26 male patients and 40 female patients), with their age ranging from 19 to 68 years. The control group consisted of 66 healthy adults (36 male individuals and 30 female individuals). Their age ranged from 20 to 60 years and they did not have any impairment in renal function or any complaints concerning their voice. All participants underwent evaluation of their voice acoustically and aerodynamically. Acoustic analysis was performed using computerized speech lab. The acoustic parameters studied include average pitch, jitter, shimmer, and noise-to-harmonic ratio. Aerodynamic analysis was performed using Aerophone II Model 6800. The aerodynamic parameters studied include vital capacity, maximum phonation time, phonation quotient, mean flow rate, subglottic pressure, and glottal efficiency. The data were analyzed using the independent t-test to compare the significance of difference between means across the two groups. Results In acoustic analysis, there was a significant increase in pitch in male patients with CRF and an increase in shimmer with borderline significance in the total group with CRF. The total group as well as the female subgroup with CRF showed a significant increase in noise-to-harmonic ratio. With respect to the aerodynamic analysis, the total group as well as the male and female subgroups with CRF showed a significant decrease in the vital capacity. There was also a significant decrease in the maximum phonation time in the total and female subgroup with CRF. Conclusion Participants with CRF exhibit clinical evidence of voice disorders both acoustically and aerodynamically. Hence, the present study sheds light on the interplay of different body systems and laryngeal muscles.

Background Many researches cited that dyslalia is often associated with behavioral problems. However, the exact behavioral problems in the dyslalia children needs more researches. Aim The present study aimed to assess the different behavioral and psychological problems among children with dyslalia to help to provide an effective therapeutic strategy for these children. Methods The study was conducted on 80 children with different types of dyslalia diagnosed by Arabic Articulation Test (study group) and on 50 normal children (control group). The children’s behavioral profile was assessed via the Child Behavior Check List (CBCL). Results Results of the study showed that there were significantly higher percentage of children with dyslalia had delinquent behavior, lower competence level, activities level and school performance level. Also, there were significantly higher mean scores in nearly all the domains of the CBCL except for anxious/depression and social scores in the dyslalia group however, their scores did not reach the abnormal range. Conclusion Articulation problems showed broad relations to behavioral problems (especially externalizing problems and competence levels). These findings suggests that psychologists and other mental health professionals can play many roles in working directly with families of children with dyslalia. Increased collaboration with phoniatricians and specialists can facilitate effective phoniatric and psychiatric care.

Context Speech of prelingual hearing impaired (HI) speakers is commonly characterized by the presence of resonance abnormalities which is related with nasality. Aim To investigate and compare nasalance scores of Egyptian HI children including cochlear implant (CI) and hearing aid (HA) users with normal hearing (NH) children. Settings and design It is an observational case–control study. Patients and methods The study consisted of group I: 41 HA children, group II: 24 CI children, and the control group: 31 age‑matched and sex‑matched children with NH. Nasometer II 6200 was used for evaluation of their nasalance scores. Statistical analysis used IBM SPSS, version 20, was used. Kruskal–Wallis and one‑way analysis of variance tests were performed to compare the mean differences between the nasalance scores of the three studied groups. While Mann–Whitney and post‑hoc tests were used for pairwise comparison. A correlation analysis was computed between the nasalance scores and many parameters using Spearman’s and Pearson’s coefficients. Results For oral sentence, both CI and HA children showed higher nasalance values in comparison with NH children. However, lower nasalance scores were observed for the nasal sentence. CI experience and enrollment into language therapy were found to have an effect on nasalance scores. Conclusions Resonance quality of the HI children is still at risk despite the fact that a significant number of them demonstrate normal resonance.
