“Lombard Effect” and Voice Changes in Adductor Laryngeal Dystonia: A Pilot Study.

Objectives: The aim was to describe the acoustic, auditory-perceptive, and subjective voice changes under the Lombardeffect (LE) in adductor laryngeal dystonia (AdLD) patients.Methods: Subjective perception of vocal effort (OMNI Vocal Effort Scale OMNI-VES), Maximum Phonation Time (MPT),and the perceptual severity of dysphonia (GRBAS scale) were assessed in condition of stillness and under LE in 10 AdLDpatients and in 10 patients with typical voice. Speakers were asked to produce the sustained vowel /a/ and to read a phoneti-cally balanced text aloud. Using the PRAAT software, the following acoustic parameters were analyzed: Mean Pitch (Hz), Mini-mum and Maximum Intensity (dB), the Fraction of Locally Unvoiced Frames, the Number of Voice Breaks, the Degree of VoiceBreaks (%), the Cepstral Peak Prominence-Smoothed (CPPS) (dB).Results: Under LE, the AdLD group showed a decrease of both G and S parameters of GRBAS and subjective effort, meanMPT increased significantly; in the controls there were no significant changes. In both groups under LE, pitch and intensity ofthe sustained vowel /a/ significantly increased consistently with LE. In the AdLD group the mean gain of OMNI-VES score andthe mean gain of each parameter of the speech analysis were significantly greater than the controls’ ones.Conclusion: Auditory feedback deprivation obtained under LE improves subjective, perceptual-auditory, and acousticsparameters of AdLD patients. These findings encourage further research to provide new knowledge into the role of the audi-tory system in the pathogenesis of AdLD and to develop new therapeutic strategies.Key Words: acoustic analysis, adductor laryngeal dystonia, audio-vocal feedback control, Lombard effect.Level of Evidence: 4Laryngoscope, 134:3754–3760, 202

Multidimensional voice assessment after Lee Silverman Voice Therapy (LSVT®) in Parkinson's disease

Objective: To investigate the effectiveness of Lee Silvermann Voice Treatment (LSVT®) in improving prosody in patients with Parkinson's disease over medium-term follow-up. Methods: 15 patients with Parkinson's disease were assessed before LSVT®, within one week, and 3 and 6 months after treatment. Subjective and objective evaluation included: Voice Handicap Index - 10 (VHI-10), perceptual assessment by GRBAS scale and item 18 of the Unified Parkinson's Disease Rating Scale III (UPDRS III), maximum phonation time (MPT /s/) and acoustic analysis by means the Voice Range Profile (VRP) and the "Intonation Stimulability Protocol" of the Motor Speech Profile (MSP). Results: A significant increase of the mean values of Imax and rF0 was observed until 6 months post-therapy (p < 0.001), whereas Running Speech Standard Deviation (rSTD) (p = 0.004), Amplitude Variability (rVAm) (p = 0.02) and Frequency Variability (rvF0) (p = 0-01) improved significantly after 3 months, but returned to pre-therapy levels after 6 months. The score of item 18 of the UPDRS III increased significantly early post-therapy (p = 0.03), but did not maintain the improvement at 3 and 6 months. Median values of Grade (G), Asthenia (A) and mean values VHI-10 score significantly decreased at each post-therapy control (p < 0.05). Conclusions: In addition to the subjective and perceptual beneficial effect of LSVT®, we found a long-lasting increase of loudness and fundamental frequency. There was also improvement of acoustic parameters related to prosody, although it was temporary

Voice Telerehabilitation in Iatrogenic Unilateral Vocal Fold Paralysis: From Necessity to Opportunity in the COVID-19 Time

Objective: To evaluate results of telerehabilitation (TR) during the coronavirus disease 2019 pandemic for the treatment of dysphonia caused by permanent post-thyroidectomy unilateral vocal fold paralysis (UVFP). Methods: Forty subjects with post-thyroidectomy UVFP (onset <1 month) underwent TR. Videostrobolaryngoscopy, acoustic and perceptual voice analysis and patient self-assessment were carried out in person before, at the end of TR and 6 months later. Results: Twenty-five subjects spontaneously recovered full vocal fold motility at some time during follow-up, whereas 15 had a permanent UVFP at the end of the follow-up period. These subjects constituted our study group. At the early posttherapy control 10/15 subjects (66.6%) showed a complete glottal closure, while in 5/15 (33.3%) a glottal gap remained (P = 0.03). These results did not change 6 months after TR. At the late posttherapy control the maximum phonation time improved significantly (P = 0.02). Both post-therapy Voice Handicap Index scores were significantly lower than the pre-therapy ones (P = 0.04). Grade, Breathiness, and Asthenia parameters of the Grade-Roughness-Breathiness-Asthenia-Strain scale improved 6 months after TR (P < 0.05). The number of voice signals suitable for acoustic analysis increased significantly after therapy. Finally, 87% of patients were satisfied with TR. Conclusions: With careful patient selection, TR may be considered as a promising method for voice therapy in postthyroidectomy UVFP.

Oropharyngeal Dysphagia After Hospitalization for COVID-19 Disease: Our Screening Results

A high percentage of patients suffered symptoms also after recovery from the Coronavirus Disease—2019 (COVID-19) infection. It is not well clear what are the specific long-term sequelae (complications and symptoms). During the acute phase the patients may develop a multi-organ system pathology including aerodigestive tract. As the pathophysiology of COVID-19 emerges, the aim of our study was to describe the prevalence of oropharyngeal dysphagia after COVID-19 disease. From March to July 2020 we enrolled patients recovered from SARS-CoV-2 infection who had been previously hospitalized for the disease. They were screened for dysphagia by mean of the Eating Assessment Tool-10 (EAT-10). The cases with EAT-10 score > 3 were graded for the aspiration risk by applying the Gugging Swallowing Screen (GUSS) and were submitted to the Swal-QoL questionnaire. The cases with a GUSS score > 19 were subjected to FEES. 8/117 (7%) patients had positive screening result. 4/8 (50%) revealed an abnormal health related quality of life in oropharyngeal dysphagia with a mean Swal-QoL score of 69.73. The most affected domain was the “time of meals” (mean score 65) following by the “sleep” (mean score 66) and “eating desire” (mean score 72). 1/8 cases showed increased risk for aspiration and did not showed endoscopic signs of oropharyngeal dysphagia. Our results showed that the prevalence of upper dysphagia after hospitalization for SARS-CoV-2 is not anecdotal and that probably this long-lasting sequela has a psychogenic etiology

Gender-related differences in the prevalence of voice disorders and awareness of dysphonia

Objective: Considering the impact of dysphonia on public health and the increasing attention to patient-centred care, we evaluated sex-related differences in the prevalence of benign voice disorders, awareness of dysphonia and voice therapy (VT) results. Methods: One hundred and seventy-one patients, 129 females and 42 males, with functional or organic benign dysphonia underwent Voice Handicap Index (VHI), auditory-perceptual dysphonia severity scoring (GRBAS) and acoustic analysis (Jitter%, Shimmer%, NHR) before and after VT. Results: Prevalence of each voice disorder was significantly higher among females. Mean time-to-diagnosis (time elapsed until medical consultation) was not different between males and females. The refusal of therapy and VT adherence (mean number of absences and premature dropout) were similar in the two groups. Pre-VT VHI and "G" parameter were worse in women. The percentage of women with abnormal acoustic analysis was significantly higher. Post-VT VHI gain was higher in women, whereas "G" parameter improvement did not differ by sex. Conclusions: Our study showed a higher prevalence of voice disorders in females. Awareness of dysphonia was not gender related. Females started with worse voice subjective perception and acoustic analysis, but they perceived greater improvement after therapy

Long-term voice outcomes and quality of life after open partial horizontal laryngectomy type II vs. total laryngectomy: A cross-sectional study

Objectives: We aim to analyse long-term voice outcomes and quality of life (QoL) in patients undergoing open partial horizontal laryngectomy type II (OPHL type II) and to compare them to those obtained by patients undergoing total laryngectomy (TL) with voice prosthesis (VP). Design: Cross-sectional cohort study. Setting: Patients undergoing surgery for advanced laryngeal cancer, assessed during the usual follow-up consultations at the Phoniatric Unit (February 2020-December 2020). Participants: Forty-five patients were enrolled and divided into two groups: OPHL group and TL group. Main outcomes measures: Acoustic analysis, maximum phonation time, INFV0 scale, I-SECEL, UW-QoL-V4 and MDADI questionnaires were used to assess the long-term outcomes. Results: Voices of patients undergoing OPHL Type II were worse than those of laryngectomised patients with VP. Nevertheless, scores in voice and dysphagia-related QoL were comparable and scores in the social domain of QoL were higher in OPHL group. Conclusions: Open partial horizontal laryngectomy Type II allows an acceptable voice recovery and

COVID-19 atypical Parsonage-Turner syndrome: a case report

Background Neurological manifestations of Sars-CoV-2 infection have been described since March 2020 and include both central and peripheral nervous system manifestations. Neurological symptoms, such as headache or persistent loss of smell and taste, have also been documented in COVID-19 long-haulers. Moreover, long lasting fatigue, mild cognitive impairment and sleep disorders appear to be frequent long term neurological manifestations after hospitalization due to COVID-19. Less is known in relation to peripheral nerve injury related to Sars-CoV-2 infection. Case presentation We report the case of a 47-year-old female presenting with a unilateral chest pain radiating to the left arm lasting for more than two months after recovery from Sars-CoV-2 infection. After referral to our post-acute outpatient service for COVID-19 long haulers, she was diagnosed with a unilateral, atypical, pure sensory brachial plexus neuritis potentially related to COVID-19, which occurred during the acute phase of a mild Sars-CoV-2 infection and persisted for months after resolution of the infection. Conclusions We presented a case of atypical Parsonage-Turner syndrome potentially triggered by Sars-CoV-2 infection, with symptoms and repercussion lasting after viral clearance. A direct involvement of the virus remains uncertain, and the physiopathology is unclear. The treatment of COVID-19 and its long-term consequences represents a relatively new challenge for clinicians and health care providers. A multidisciplinary approach to following-up COVID-19 survivors is strongly advised
