Biobehavioral Measures of Presbylaryngeus.

OBJECTIVE: The objective of this observational study was to assess the relationship between established aging biobehavioral measures and voice decline in normally aging adults. STUDY DESIGN: Cross-sectional study. METHODS: Participants 60-85 years of age were divided into two age and sex-matched groups, based on the presence or absence of presbylaryngeus. Both groups underwent a battery of tests measuring anthropometric variables, inflammatory markers, general health measures, and vocal function parameters. Differences from the norm were calculated for all variables. Parametric and nonparametric tests were performed to assess group differences. In addition, variable selection analysis was performed to determine variables that were most influential in predicting the occurrence of presbylaryngeus in our current sample. RESULTS: Fifty-three participants were divided into age and sex-matched groups of "presbylaryngeus" (n = 26) and "non-presbylaryngeus" (n = 27). The two groups were statistically different in select measures of inflammatory markers, general health measures, and vocal function parameters. Anthropometric measures were not statistically different. Based on variable selection, the variables most predictive of the presence of presbylaryngeus were measures of the Physical Activity Scale of the Elderly, C-reactive protein, laryngeal airway resistance, and vocal roughness. CONCLUSIONS: In addition to group differences in vocal function measures, results for the presbylaryngeus group consistently trended sub-optimally on anthropometric measures, two inflammatory markers, and general health measures. These results suggest that this sample of individuals with presbylaryngeus demonstrated greater biobehavioral deficits associated with aging as compared to age and sex-matched non-presbylaryngeus individuals.

Menstrual Cycle, Vocal Performance, and Laryngeal Vascular Appearance: An Observational Study on 17 Subjects.

OBJECTIVE: To assess the anatomical and functional features of the vocal folds during different phases of the female menstrual cycle. METHODS: An observational study of 17 healthy fertile female volunteers not using hormonal contraception was carried out. Each volunteer underwent two examinations: first, during the early days of the menstrual cycle when progesterone levels are low (p-depletion), and second, during premenstruation when progesterone levels are high (p-peak). The workup included blood hormone levels, Voice Handicap Index, acoustic analysis, rigid telescopy, stroboscopy, and narrow band imaging. The videos were evaluated by blinded observers. RESULTS: The participants' mean age was 31.7 ± 5.6 (range 23-43). Progesterone levels were 13- to 45-fold higher in p-peak relative to p-depletion. No significant differences were detected in Voice Handicap Index scores, stroboscopic reports, or acoustic analysis between p-peak and p-depletion examinations. Analyzing the rigid telescopy and narrow band imaging videos, the observers tended to estimate the different laryngeal subsites more vascularized during the p-peak examination. Moreover, this tendency was significantly correlated with blood progesterone levels during the p-depletion examinations; the lower the blood progesterone levels were during p-depletion, the higher the probability for the observers to estimate the p-peak examinations more vascularized (P value = 0.024). CONCLUSIONS: Alterations in laryngeal vascular characteristics are evident throughout the menstrual cycle and may suggest increased congestion during premenstrual days. Variations in progesterone levels during the menstrual cycle correlate with laryngeal vascular changes. Hormone-related alterations in vocal folds' vascularity may have a role in the variability of vocal performance in certain women.

Unexplained Profound Hypoglycemia After Vocal Fold Lipoinjection.

Vocal fold injection is used for the management of glottal incompetence from various causes. The procedure is well tolerated and has few reported complications. We present a case of a 66-year-old man with long-lasting hoarseness secondary to vocal fold atrophy, who underwent an uneventful bilateral vocal fold injection with autologous fat. While in the recovery area, he experienced profuse sweating approximately 30 minutes after the surgical procedure. His blood glucose value was measured at 24 mg/dL, and plasmatic insulin level was 246 mU/L. To our knowledge, this is the first reported case of a systemic side effect after vocal fold lipoinjection.

Is Menstrual Dysphonia Associated With Greater Disability and Lower Quality of Life?

OBJECTIVES: The aim of the present study had been to examine the relationships between menstrual dysphonia and measures of psychosocial distress, in a sample of female professional voice users. DESIGN AND METHODS: This is a prospective study of 52 consecutive professional voice users, aged 18-40 years, affected by transient dysphonia related to the menstrual cycle and recruited in the Division of Phoniatrics and Audiology of the Second University of Naples, from April 2011 to September 2014. The following evaluation protocol was used: videoendoscopy, the GIRBAS scale, the Voice Handicap Index, and the determination of sexual hormonal plasma levels both during the menstrual and the luteal phase of the cycle. Furthermore, we measured, in all patients, the levels of perceived disability and quality of life during and after the dysphonia episodes by means of the Manchester Short Assessment of Quality of Life and the Sheehan disability scale. RESULTS: Laryngoscopic evaluation revealed that only minor morphologic changes were present during the first days of the follicular phase, usually returning to normal morphology after the menstrual period was over. However, we found that dysphonia episodes of varying degree were present in most evaluated subjects; women with a moderate degree of dysphonia also had a lower quality of life and greater overall disability, during menses. CONCLUSIONS: Despite minimal morphologic signs of laryngeal pathology, menstrual dysphonia might represent a disease which is frequent among female professional voice users, which in turn is associated with a certain degree of disability and lower quality of life during premenstrual and menstrual phases.

Voice characteristics of acromegaly.

Acromegaly's effect on voice is still indefinite. We aimed to define acoustic characteristics of patients with acromegaly. Cross-sectional case-control study was designed. Thirty-seven patients with acromegaly and 30 age- and sex-matched healthy controls were included. Fundamental frequency (F0) and measurements related to frequency, amplitude, noise and tremor of the obtained voice sample were analyzed using Multi-Dimensional Voice Program. Absolute jitter (Jita) and jitter percent (Jitt), shimmer in decibel and shimmer percent, noise to harmonic ratio and soft phonation index, fundamental frequency tremor frequency and frequency tremor intensity index represented the parameters related to frequency, amplitude, noise and tremor of the voice sample, respectively. Patients with acromegaly, especially the uncontrolled patients, exhibited significant differences in frequency perturbation measurements. Jitt of all patients and Jita of uncontrolled patients were significantly higher than that of control group (p = 0.044 and p = 0.043, respectively). Jitter which is a measure of frequency perturbation can be assumed as an indicator of hoarse and deepened voice. Jita of all patients and Jitt of uncontrolled patients were elevated, but not reaching a statistical significance. Controlled and active patients had similar analysis of acoustic parameters. In the correlation analysis, shimmer and IGF-1 (insulin like growth factor 1) was found to be positively correlated in all patients with acromegaly and in female patients. When the p value is adjusted according to Bonferroni correction regarding the use of ten parameters for acoustic analysis (so adjusted p is <0.005), all the statistically significant findings become insignificant. Considering the parameters test different properties of voice, it is reasonable to pay attention to the findings. Patients with acromegaly have increased frequency perturbations measures, but this increase is non-significant according to Bonferroni correction. This may be perceptually sensed as hoarse voice. Amplitude perturbations within the voice of the patients with acromegaly are positively correlated with IGF-1 levels, this correlation is also non-significant according to Bonferroni correction.

Vocal symptoms in women undergoing in vitro fertilization.

OBJECTIVE: The aim of this study was to investigate changes in vocal symptoms in relation to estrogen level in women undergoing in vitro fertilization. MATERIALS AND METHODS: A total of 31 women were enrolled in this study. The following vocal symptoms were investigated: vocal tiring or fatigue, vocal straining, throat clearing, lump sensation, hoarseness, and aphonia (or loss of voice). The severity of these symptoms was graded from 0 to 4, where 0 means absence of the symptom and 3 means severe symptom presence. The frequency of these symptoms was evaluated in the first visit at presentation; second visit, 4 to 5 days after ovarian stimulation; and third visit, 8 to 10 days after stimulation. In the second and third visits, the estradiol levels were measured. RESULTS: The mean age was 32.33 ± 4.80 years. Ten of the 31 patients had at least 1 vocal symptom. The most common vocal symptom in all 3 visits was throat clearing, with an incidence of 22.6% in the first and second visits and 19.4% in the third visit. This was followed by vocal fatigue or tiring and lump sensation, with an incidence of 9.68% for both. The incidence of all the vocal symptoms as well as their severity did not change throughout the visits, except for throat clearing, which has decreased in the third visit but not significantly (22.6% vs 19.4%, P = 1). Subjects with vocal symptoms had lower estradiol level compared with those with no vocal symptoms; however, the difference was not statistically significant (P = .108 and .267, respectively). CONCLUSION: Subjects undergoing in vitro fertilization do not experience changes in their vocal symptoms when present, except for throat clearing. However, those with vocal symptoms have lower levels of estradiol compared with those with no vocal symptoms.
