Social anxiety disorder in adolescents who stutter: A risk for school refusal.

BACKGROUND: Stuttering is a childhood-onset fluency disorder. Part of the counseling for middle and high school students with persistent stuttering is related to school refusal. Anxiety disorders are known to contribute to school refusal. However, it is not known whether social anxiety disorder (SAD) is a factor in school refusal among adolescents who stutter. METHODS: In our first study, we examined the relationship between school refusal and SAD in 84 middle and high school students who stutter; 26% of the 84 students were in the school refusal group and the remaining 74% were in the school attendance group. The second study examined whether SAD was associated with 10 factors related to speech and stuttering frequency using the Japanese version of the Liebowitz Social Anxiety Scale for Children and Adolescents to determine the presence of SAD. Of the 84 students in the first study, 40 participated in the second study. RESULTS: The school refusal group of adolescents who stutter had significantly higher rates of SAD than the school attendance group. Fifty percent of adolescents who stutter met the criteria for SAD. Moreover, adolescents who stutter with SAD had significantly higher scores on the items "When speaking in public, do you experience tremors in your limbs?" and "After you stutter, do you have negative thoughts about yourself?" than the adolescents who stutter without SAD. CONCLUSIONS: When examining adolescents who stutter, checking for comorbid SAD may lead to better support. Moreover, noticing their repetitive negative thinking, nervousness, and trembling during speech may help to resolve SAD.

Type I Thyroplasty Is Safe in Patients Undergoing Antithrombotic Therapy.

INTRODUCTION: Type I thyroplasty is one of the most useful surgeries for unilateral vocal fold paralysis. The study objective was to determine whether type I thyroplasty is safe and perioperative antithrombotic management is acceptable in patients undergoing antithrombotic therapy. METHODS: This is a single-hospital retrospective cohort study. The records of 204 patients who underwent type I thyroplasty at a Japanese university hospital, between 2008 and July 2018 were reviewed. We compared the prothrombin time international normalized ratio, prothrombin time, operative time, intraoperative blood loss, and intra- and postoperative complications between patients who did and did not receive antithrombotic therapy. RESULTS: Of 204 patients, 51 (25%) received antithrombotic therapy (antithrombotic group). The remaining 153 patients were assigned to the control group. There were no significant differences in operative time, intraoperative blood loss, or intraoperative complications between the two groups. Sixteen (31%) patients in the antithrombotic group had a hemorrhage or hematoma in the vocal fold mucosa postoperatively, no patient had airway obstruction necessitating tracheostomy, and all patients recovered with follow-up observation only. There were no cases of intraoperative or postoperative complications, such as ischemic heart disease, ischemic stroke, or deep vein thrombosis. CONCLUSION: Type I thyroplasty with careful pre- and postoperative management is safe in patients undergoing antithrombotic therapy.

Awareness of stuttering in Japanese children aged 3-7 years.

BACKGROUND: Boey et al. (2009) devised a questionnaire for measuring children's awareness of stuttering and showed that even very young children were often aware of their stuttering. There has been no replication of studies using Boey et al.'s parent-reported questionnaire. The aim of this study was to test whether using Boey et al.'s seven questions, developed for a Dutch speaking population could be effective for measuring the awareness of stuttering in Japanese children. METHODS: Participants were 54 children who stutter (CWS) aged 3-7 years. Parents answered seven questions about their child's awareness of stuttering according to the questions developed Boey et al. RESULTS: Parental-reported observations of the child responses citing at least one awareness incident were 76%. The percentage of stuttering children with awareness of their own speech difficulties, according to chronological age, were as follows: 70% at age 3 years; 67% at age 4 years; 75% at age 5 years; 81% at age 6 years; and 90% at age 7 years. CONCLUSIONS: We found that even at age 3 years, many CWS were already aware of their stuttering. The similarity of the data with the seminal study by Boey et al. suggests that the question-based assessment is reproducible even in a country with a different spoken language. The seven questions in Boey et al. are useful for evaluating whether children's awareness of stuttering could contribute to a clinical decision as well as stuttering severity.

Tracheoesophageal diversion improves oral uptake of food: a retrospective study.

PURPOSE: Tracheoesophageal diversion (TED) is an effective therapeutic procedure for intractable aspiration. In this study, we performed TED in cases of intractable aspiration and/or repetitive pneumonia, investigated the main route of nutritional uptake after the procedure, and evaluated the swallowing method using videofluoroscopy. We also evaluated the validity of TED for treating intractable aspiration. METHODS: We retrospectively reviewed 44 patients (30 male and 14 female patients; median age, 55 years; range 15-85 years) who underwent TED for the treatment of intractable aspiration between January 2008 and December 2017. We examined the route of nutritional uptake before and after the operation and performed videofluoroscopy to detect the swallowing method after the operation. RESULTS: The percentage of patients with oral intake increased from 21% (9/44) before TED to 56% (25/44) within 1 month after TED (p < 0.01); this percentage included patients with poor preoperative swallowing function. Overall, 60% patients who were able to communicate and mobilize using a wheelchair as well as 92% patients who were able to communicate and mobilize in the supine position were able to consume food orally. We subsequently performed videofluoroscopy in 24 of the 25 patients with oral intake and assessed the passage route of the contrast agent, which was found to move through the laryngeal route in 54% of these patients. CONCLUSION: TED may be suitable for the treatment of intractable aspiration and can improve oral intake, particularly in patients with good mobility and communication ability.

Videoendoscopy worsens swallowing function: a videofluoroscopic study. A randomized controlled trial.

Aspiration pneumonia is a cause of mortality in the elderly. Evaluating swallowing function is important. Videofluoroscopy and flexible endoscopic evaluation of swallowing are comparable; however, observing all swallowing dynamics is impossible using the latter approach. We examined the significance of flexible endoscopic evaluation of swallowing using videofluoroscopy. Thirty-seven patients with dysphagia [70.0 ± 8.9 (range 49-84) years] were included. In random order, patients underwent videofluoroscopy with 10 cc contrast material, once without, and once with an endoscope inserted. Laryngeal elevation delay time, Penetration-Aspiration Scale score, and Pharyngeal Residue Severity Rating Scale score were evaluated. Laryngeal elevation delay time without or with endoscope insertion was similar (0.35 ± 0.16 s vs. 0.36 ± 0.16 s, P = 0.29). The Penetration-Aspiration Scale (3.59 ± 2.71 vs. 4.41 ± 2.85; P < 0.001) and Pharyngeal Residue Severity Rating Scale (0.97 ± 0.93 vs. 1.46 ± 1.10; P < 0.001) scores differed significantly. The cases that showed no aspiration without endoscope insertion showed greater aspiration with endoscope insertion, and the cases that did not show aspiration with an endoscope inserted also showed no aspiration without an endoscope. Flexible endoscopic insertion resulted in more severe aspiration and residue than non-insertion, as assessed using videofluoroscopy.

Tracheoesophageal Diversion and Puncture for Preserving Phonation in Intractable Aspiration: A Case Series.

OBJECTIVE/HYPOTHESIS: Tracheoesophageal diversion (TED) can prevent damage to the respiratory system in patients with swallowing disorders and/or repetitive aspiration pneumonia; however, TED may cause the loss of phonation. Our previous study demonstrated that TED with tracheoesophageal puncture (TEP) prevents aspiration while retaining phonation. In this study, we aimed to further evaluate the feeding status and phonation of patients who underwent TED with TEP to verify the reproducibility of this procedure. STUDY DESIGN: Case series study. METHODS: We retrospectively reviewed the medical records of 11 patients who underwent TED with TEP for intractable aspiration from February 2017 to August 2019 at Fukuoka Sanno Hospital. We evaluated the preoperative penetration aspiration score (PPAS), daily activities, preoperative and postoperative food intake level scale (FILS) score, nutrition route, maximum phonation time(MPT), and postoperative communication method. RESULTS: The study population included 10 men and 1 woman (mean age, 66 years; range, 44-81) with a PPAS of 6.8 ± 1.0. The FILS score changed from 2.1 ± 0.5 preoperatively to 7.5 ± 2.0 postoperatively (paired t-test, P < .05), while the MPT changed from 7.9 ± 4.1 to 10.3 ± 4.2 s (paired t-test, P = .9). Preoperatively, a gastric fistula (eight patients [73%]) was the main nutrition route, followed by a gastric tube (two patients [18%]). Postoperatively, the main nutritional route for eight patients (73%) was oral, while the remaining three patients (27%) used the oral route occasionally. All patients maintained laryngeal phonation function, and eight (73%) used only laryngeal phonation for communication. CONCLUSIONS: Patients with intractable aspiration who wish to retain phonatory function should be advised to undergo TED with TEP. LEVEL OF EVIDENCE: 4 Laryngoscope, 131:E1965-E1970, 2021.

Kinematic evaluation of penetration and aspiration in laryngeal elevating and descending periods.

OBJECTIVES: It is important to evaluate swallowing movements by dividing them into periods of laryngeal closure and release. The purpose of this study was to evaluate penetration-aspiration (PA) according to human pathophysiology and to identify the factors for predicting PA. STUDY DESIGN: Case-control study. METHODS: Eighty-one patients with complaints of dysphagia caused by various etiologies were enrolled in this study. Videofluoroscopic swallowing studies were conducted, and the spatial and temporal factors were analyzed by computer-assisted motion analysis. RESULTS: The initiation of laryngeal vestibule closure in the laryngeal elevating period and its duration in the laryngeal descending period were significant factors for evaluating PA. CONCLUSION: A knowledge of the delay of laryngeal vestibule closure in the laryngeal elevating period and its short duration in the laryngeal descending period could make it easier to evaluate the risk of PA. LEVEL OF EVIDENCE: 3b. Laryngoscope, 128:806-811, 2018.

A case of multiple system atrophy-parkinsonian type with stuttering- and palilalia-like dysfluencies and putaminal atrophy.

Both developmental and acquired stuttering are related to the function of the basal ganglia-thalamocortical loop, which includes the putamen. Here, we present a case of stuttering- and palilalia-like dysfluencies that manifested as an early symptom of multiple system atrophy-parkinsonian type (MSA-P) and bilateral atrophy of the putamen. The patient was a 72-year-old man with no history of developmental stuttering who presented with a stutter for consultation with our otorhinolaryngology department. The patient was diagnosed with MSA-P based on parkinsonism, autonomic dysfunction, and bilateral putaminal atrophy revealed by T2-weighted magnetic resonance imaging. Treatment with levodopa improved both the motor functional deficits related to MSA-P and stuttering-like dysfluencies while reading; however, the palilalia-like dysfluencies were much less responsive to levodopa therapy. The patient died of aspiration pneumonia two years after his first consultation at our hospital. In conclusion, adult-onset stuttering- and palilalia-like dysfluencies warrant careful examination of the basal ganglia-thalamocortical loop, and especially the putamen, using neuroimaging techniques. Acquired stuttering may be related to deficits in dopaminergic function.

Long-term outcomes of type I thyroplasty with silicone implantation: Assessment of excised laryngeal tissue from a patient with secondary hypopharyngeal carcinoma.

Here we describe the long-term outcomes of type I thyroplasty (TP-I) with silicone block implantation through histopathological assessments in a male patient who underwent pharyngolaryngectomy for secondary hypopharyngeal carcinoma 7 years after silicone implantation. A 66-year-old man presented with esophageal carcinoma and underwent subtotal esophagotomy. Subsequently, his left vocal fold exhibited fixation in a paramedian position, and he underwent TP-I with silicone block implantation 2 years after the primary esophageal surgery. His voice quality improved; however, he developed glottic carcinoma in the right vocal fold 6 months after TP-I and underwent laser cordectomy. Glottic carcinoma recurred 21 months later, and he underwent laser cordectomy again. Five years after the second laser surgery, he underwent pharyngolaryngectomy and neck dissection for hypopharyngeal carcinoma detected in the right pyriform sinus. We histopathologically examined a horizontal section of the resected larynx to assess silicone implant-related changes. Although migration of the silicone implant was not observed, a very mild foreign body reaction occurred around the implant. The patient is currently in remission. Our findings suggest that silicone implants are suitable for TP-I due to their remarkable affinity for human tissue and the low risk of a tissue reaction.

Evaluation of water content around airway in obstructive sleep apnea patients using peripharyngeal mucosal T2 magnetic resonance imaging.

INTRODUCTION: Obstructive sleep apnea (OSA) is common sleep disorder characterized by repetitive episodes of airway closure which usually occurs in the retropalatal region of the oropharynx. It has been known that upper airway mucosa in OSA patients is described as edematous, but not fully clarified. OBJECTIVES: This study aimed to investigate and establish magnetic resonance imaging (MRI) parameter to estimate tissue water content at retropalatal level and its relationship with sleep parameters in OSA patients. METHODS: Forty-eight subjects with OSA underwent overnight polysomnography and cervical MRI with 1.5-tesla [mean (SD) age 55 (14) years and apnea-hypopnea index (AHI) 45.2 (26.1) events/hour, 79.2% male]. On the axial T2-weighted images from epipharynx to oropharynx, the signal intensities of masseter muscle and peripharyngeal mucosa [T2 mucous-to-masseter intensity ratio (T2MMIR)], was used as water content estimation in the retropalatal region. Partial correlation analysis was performed to examine the correlation between T2MMIR and polysomnography parameters. RESULTS: We found that there were strong and positive correlations between the T2MMIR and AHI (r = 0.545, P < 0.05), supine AHI (r = 0.553, P < 0.05) and REM AHI (r = 0.640, P < 0.01) by partial correlation analysis. Besides, in patients with less efficient sleep who had more stage 1 sleep, significantly higher T2MMIR was noted (r = 0.357, P < 0.05). CONCLUSIONS: This study confirmed that peripharyngeal T2MMIR can be a simple parameter representing peripharyngeal tissue water contents related to severe OSA.

Tracheobronchomegaly associated with laryngo-tracheal amyloidosis: First case report.

Tracheobronchomegaly (TBM) is a rare enlargement of the tracheal cartilage, also known as Mounier-Kuhn syndrome (MKS). Here, we describe an unusual case of acquired TBM in an adult, caused by amyloid regeneration and associated tracheal weakening, rather than by MKS. CT scan and fiberscopic examination of a 55-year-old woman suffering from severe dyspnea revealed TBM and subglottic stenosis, which was caused by deposition of amyloid tissue. We performed a tracheostomy and vaporized the subglottic stenosis with a CO2 laser, after which we installed a silicone T-tube. After the first operation, re-stenosis occurred, and the procedure was repeated; stenosis was subsequently cured and the dyspnea disappeared, after which the tracheostomy could be closed. This is the first report of adult TBM associated with amyloid deposition in the subglottis and trachea. This diagnosis is very difficult, as amyloid deposition in the trachea can have various clinical presentations.

Videofluoroscopic assessment of pharyngeal stage delay reflects pathophysiology after brain infarction.

OBJECTIVES/HYPOTHESIS: The pathophysiology of dysphagia caused by brain infarction varies with the site of the lesion in the brain. Patients with suprabulbar lesions have demonstrated delayed triggering of pharyngeal stage including delayed laryngeal elevation. Patients with severe pharyngeal stage delay have a high risk of intractable aspiration to the lower respiratory tract. Despite this, few studies have compared the pharyngeal stage delay with the lesion site. We defined a new temporal parameter of the pharyngeal stage delay to assess laryngeal elevation delay against the bolus inflow into the pharyngeal space. This study aimed to elucidate whether this parameter of pharyngeal stage delay is clinically useful to assess the pathophysiology of brain lesions after brain infarction. STUDY DESIGN: Case-control study. METHODS: Videofluoroscopic assessment of swallowing examinations was performed from January 7, 2000 to March 29, 2011 at Kyushu University Hospital. We evaluated the pharyngeal stage delay using motion analysis on videofluoroscopic swallowing examination in patients with normal swallowing and brain infarction patients divided into pathophysiologic lesion groups. Laryngeal elevation delay time and pharyngeal delay time were analyzed. RESULTS: Significant differences in laryngeal elevation delay time were observed between each pathophysiologic lesion group. However, pharyngeal delay time remained similar among groups. Brain infarctions of corticobulbar tract and basal ganglion were significantly associated with laryngeal elevation delay time prolongation. CONCLUSIONS: Laryngeal elevation delay time with low-viscosity contrast medium is a recommended parameter to discriminate the corticobulbar tract and the basal ganglion lesion.

Multidimensional voice evaluation in pretreatment glottic carcinoma.

It is generally accepted that, in glottic carcinoma, the voice will deteriorate, even in the early stages. This paper reports the degree of hoarseness and multidimensional vocal evaluation of glottic carcinoma patients. Forty-seven male glottic carcinoma patients and a control group of 13 normal subjects were included in this study involving psychoacoustic evaluation by doctors, acoustic analysis, phonogram, maximum phonation time and stroboscopy before treatment. A normal voice or mild hoarseness by psychoacoustic evaluation was found in 35% of cases with T1 and T2 glottic carcinoma. Patients with psychoacoustically inferior vocalization had high scores on acoustic analysis, small phonogram areas, and short maximum phonation time. Stroboscopy revealed attenuation or disappearance of the mucosal wave on the tumor side in all cases, whether the acoustic analysis data were within or beyond the normal limits. We identified two conditions offering superior vocalization in glottic carcinoma patients: (1) the lesion should be unilateral, and (2) the lesion should be flat with no protrusion. We should evaluate patients with glottic carcinoma not only with vocal examination but also using stroboscopy before biopsy.
