Effect of renal failure on voice.

The objective of this case-control study was to assess the impact of dysphonia on quality of life and to report the perceptual and acoustic findings in patients with chronic renal failure. A total of 22 patients with chronic renal failure and 18 healthy controls were recruited. Patients were asked to complete the Voice Handicap Index (VHI)-10 to assess the impact of dysphonia on quality of life. Perceptual evaluation of patients' voice recordings using the GRBAS classification was performed. Acoustic analysis was also conducted. Fundamental frequency, habitual pitch, shimmer, relative average perturbation, harmonic-to-noise ratio, voice turbulence index, and the maximum phonation time were reported. The mean scores of the VHI-10 were within normative values, with no significant difference between groups. There was also no significant difference in any of the acoustic parameters or in the mean score of any of the perceptual parameters between patients and controls. We conclude that patients with renal failure do not have dysphonia with a significant impact on quality of life, as evident by the normative values of the VHI-10. There were neither perceptual nor acoustic differences between patients and controls.

Laryngopharyngeal symptoms in patients with asthma: a cross-sectional controlled study.

OBJECTIVE: To examine the frequency and severity of laryngopharyngeal symptoms in asthmatic patients. The role of laryngopharyngeal reflux disease as a co-morbid disease to asthma has not been previously reported. SUBJECTS AND METHOD: Seventy-two subjects, 36 asthmatics and 36 controls were included in this study. Demographic data included age, gender, status of asthma, use of steroid inhalers, smoking and history of allergy. Pulmonary function test was reported in 13 subjects. The evaluation consisted of filling the Reflux Symptom Index (RSI) described by Belafsky et al. The total score, frequency and average score of each laryngopharyngeal symptom was computed in both groups. RESULTS: The mean age of patients was 46.61 ± 17.59 years with a female to male ratio of 2.3:1. Twenty patients were using steroid inhalers. Close to one third were smokers (30.6%) and 55.6% had allergic rhinitis. Thirty-six percent had controlled asthma vs 64% were uncontrolled. The mean of the total RSI was significantly higher in patients compared with controls (12.03 ± 8.3 vs 6.64 ± 6.08, P value < 0.05). In the asthmatic group, 15 subjects had a positive RSI compared with only 4 in the control group (P value of 0.003). There was a significant difference in the prevalence and means of four laryngopharyngeal symptoms in patients vs controls. CONCLUSION: Laryngopharyngeal reflux disease is more prevalent and more severe in patients with asthma vs controls.

Endovascular coiling versus parent artery occlusion for treatment of cavernous carotid aneurysms: a meta-analysis.

BACKGROUND AND PURPOSE: Endosaccular coil embolization and parent artery occlusion (PAO) are established endovascular techniques for treatment of cavernous carotid aneurysms. We performed a systematic review of published series on endovascular treatment of cavernous carotid aneurysms to determine outcomes and complications associated with endovascular coiling and PAO of cavernous carotid artery aneurysms. METHODS: In September 2013, we conducted a computerized search of MEDLINE and EMBASE for reports on endovascular treatment of intracranial cavernous carotid aneurysms from January 1990 to August 2013. Comparisons were made in periprocedural complications and outcomes between coiling and PAO patients who did not receive bypass. Event rates were pooled across studies using random effects meta-analysis. RESULTS: 20 studies with 509 patients and 515 aneurysms were included in this systematic review. Aneurysm occlusion rates at >3 months after operation were significantly higher in the PAO without bypass group (93.0%, 95% CI 86.0 to 97.0) compared with the coiling group (67.0%, 95% CI 55.0 to 77.0) (p<0.01). Retreatment rates were significantly lower in the PAO without bypass group (6.0%, 95% CI 2.0 to 12.0) compared with the coiling group (18.0%, 95% CI 12.0 to 26.0) (p=0.01). Coiling patients had a similar morbidity rate (3.0%, 95% CI 2.0 to 6.0) compared with PAO without bypass patients (7.0%, 95% CI 3.0 to 12.0) (p=0.13). Coiling patients had a similar mortality rate (0.0%, 95% CI 0.0 to 6.0) compared with PAO without bypass patients (4.0%, 95% CI 1.0 to 9.0) (p=0.68). CONCLUSIONS: Evidence from non-comparative studies suggests that traditional endovascular options are highly effective in treating cavernous sinus aneurysms. PAO is associated with a higher rate of complete occlusion. Periprocedural morbidity and mortality rates are not negligible, especially in patients receiving PAO.

Effect of weight loss on voice after bariatric surgery.

OBJECTIVE: To investigate the effect of weight loss on voice. STUDY DESIGN: Prospective study. SUBJECTS: A total of 15 subjects undergoing bariatric surgery were investigated. Six subjects were lost to follow-up, and nine subjects were evaluated preoperatively and 3-6 months postoperatively. The evaluation included a questionnaire on voice quality filled by the patient, laryngeal examination, perceptual evaluation, and acoustic analysis. The questionnaire consisted of four questions: change in vocal pitch, change in vocal loudness, increase or decrease in phonatory effort, and the presence or absence of vocal fatigue. For the perceptual evaluation, a simplified version of the Grade, Roughness, Breathiness, Asthenia, Strain scale classification was used. These parameters were rated using a score ranging from zero to three where zero stands for none and three for severe. For the acoustic analysis, the following variables were measured: fundamental frequency, habitual pitch, jitter, shimmer, noise-to-harmonics ratio, voice turbulence index, and maximum phonation time. RESULTS: The mean age was 35.56 ± 9.93 years. The mean weight preoperatively and postoperatively was 112.17 and 83.61 kg, respectively. The body mass index dropped by eight points from 38.06 to 30.83. Only three of the nine patients have reported change in voice quality. The latter was described as an increase in vocal pitch in the three cases, reduced loudness and increased phonatory effort in two, and the presence of vocal fatigue in one. There was no significant difference in the mean score of any of the perceptual parameters in patients preoperatively versus postoperatively. There was also no significant difference in any of the acoustic parameters or in the laryngeal findings before and after surgery. CONCLUSION: One-third of the patients with weight loss reported change in voice quality that was not documented acoustically. The laryngeal examination is nonrevealing.
