JOURNAL FREE ACCESSA case of spasmodic-like psychogenic dysphonia (SPD) is presented. Voice examination during speech revealed pressed or strained voice quality, voice stoppages which are often described as characteristic signs of adductor spasmodic dysphonia (ADSD) . Fiberoptic laryngoscopy during phonation revealed sphincteric constriction of the larynx. Five expert otolaryngologists made perceptual assessment of the audio-recorded voice samples. All five experts agreed that the dysphonia of the patient most likely had ADSD as long as voice characteristics. The authors suspected the dysphonia of the patient to be psychogenic, mainly based on the findings in an interview, such as the fact that vocal symptoms occurred coincidentally with psychogenic dyspnea. The vocal symptoms improved to normal by voice therapy almost identical to that used to treat psychogenic aphonia. The diagnosis of psychogenic dysphonia in this case was confirmed by symptom reversibility in response to the voice therapy. These circumstances suggest a strong probability that SPD will be misdiagnosed as ADSD. An in-depth interview, comprehensive voice assessment, laryngoscopy, and diagnostic voice therapy are thus recommended in the diagnostic process of SPD and ADSD.View full abstractDownload PDF (3523K) -

JOURNAL FREE ACCESSRecently, the Voice Handicap Index (VHI) developed in the US is garnering attention as a means to assess a patient's perception of the severity of his or her voice disorder. VHI consists of a self-administered questionnaire that quantifies the degree of a patient's handicap related to voice disorders. We have translated it into Japanese and applied our version to Japanese patients with various kinds of disordered voice or dysphonia. The results were analyzed and the usefulness of our VHI was discussed. In our study, 163 patients (79 males and 84 females) were included. Mean VHI scores were 34.5/120 in males and 41.6/120 in females. In the male patients, VHI scores of those younger than 50 years old were lower than those of patients in their 50's and 60's. On the other hand, VHI scores were invariable chronologically in the female patients. Patients with functional dysphonia, vocal fold paralysis, vocal fold atrophy, or sulcus vocalis showed relatively high VHI scores. In the majority of diseases, functional and physiological scores were higher than emotional scores. In the tested patients, especially those with recurrent laryngeal nerve paralysis, vocal polyp or polypoid vocal fold, VHI scores decreased following therapeutic intervention. These findings suggest that VHI is a useful tool to monitor a patient's psychological status, to choose appropriate methods of treatment, and to assess the therapeutic outcome.View full abstractDownload PDF (905K) -

JOURNAL FREE ACCESSNewborn hearing screening was introduced in Okayama Prefecture in July 2001, and approximately 75% of newborn babies in this district are currently screened every year. As of May 2005, 48 children have been diagnosed as having bilateral hearing impairment and 43.8% of these cases involved mild to moderate hearing loss (30 dBHL to 70 dBHL) . This fact suggests that the hearing screening system can effectively identify infants even with mild to moderate hearing loss. The screening system also effectively identified hearing-impaired children without risk factors for deafness more frequently (60.4%) than those with risk factors (39.6%) . During this same period, 26 additional cases visited Kanariya Gakuen although they initially received passing results in the newborn hearing screening. Three of these cases were ultimately diagnosed as having a hearing loss, with diagnoses of acquired hearing loss caused by meningitis (1 case), bilateral progressive hearing loss (1 case), and unilateral progressive hearing loss (1 case) . These findings suggest that newborn hearing screening in Okayama Prefecture has been able to successfully detect many hearing-impaired infants from the very inception of this system. The importance of hospital-based or public health check-ups for children, however, should still be emphasized to identify hearing-impaired children who underwent no hearing screening during their infancy.View full abstractDownload PDF (760K) -
—Measured by Near-Infrared Spectroscopy—Yutaka Sato, Koichi Mori, Toshizo Koizumi, Yasuyo Minagawa-Kawai, Akih ...2006 Volume 47 Issue 4 Pages 384-389

JOURNAL FREE ACCESSNear-infrared spectroscopic measurement of cerebral hemodynamics was used to investigate cerebral dominance during auditory language processing in preschool and school-age children who stutter. Analysis-synthesized Japanese words (/itta/ and /itte/) and intonation contrasts (/itta/ and /itta?/) were used for stimuli. The baseline block contained only /itta/, whereas the contrast block consisted of either the minimal pair or intonation pair, with the contrast words presented in random order at equal probabilities. To analyze cerebral lateralization, we calculated a laterality index (LI) from the peaks of the left and right total Hb responses for each contrast block, compared to the preceding baseline block in the auditory area. The results showed that there were no significant differences in LI between the minimal pair and intonation conditions in children who stutter. Within-subject analysis showed no subject with a significant leftward shift of LI in the minimal pair condition relative to the intonation condition. These results indicate that the cerebral dominance in processing heard speech may be in disarray in children who stutter.View full abstractDownload PDF (941K)
