Methods : Thirty-five pediatric patients with vocal nodules and 32 control children without dysphonia were enrolled in this study. Their voice samples were analyzed using the Multi-Dimensional Voice Program. Acoustic parameters of voice, such as pitch period perturbation quotient (PPQ), amplitude perturbation quotient (APQ), and noise-to-harmonic ratio (NHR), were measured. Results : In phonation at a loudness of over 80 dBA, the PPQ, APQ, and NHR values of the voice significantly increased in children with vocal nodules than in the control children without dysphonia. The sensitivities and specificities of PPQ, APQ, and NHR for prediction of vocal nodules in children were 62.86% and 84.38%, 74.29% and 75.00%, and 31.43% and 93.75%, respectively. Discussion : The present findings suggest that vocal nodules affect vocal fold vibration, resulting in impaired control of pitch and loudness leading to increased noise components. NHR could be used to evaluate the efficacy of treatment, such as voice rehabilitation, in pediatric patients with vocal nodules because of its high specificity for prediction of vocal nodules in children.

Methods : Thirty-five pediatric patients with vocal nodules and 32 control children without dysphonia were enrolled in this study. Their voice samples were analyzed using the Multi-Dimensional Voice Program. Acoustic parameters of voice, such as pitch period perturbation quotient (PPQ), amplitude perturbation quotient (APQ), and noise-to-harmonic ratio (NHR), were measured. Results : In phonation at a loudness of over 80 dBA, the PPQ, APQ, and NHR values of the voice significantly increased in children with vocal nodules than in the control children without dysphonia. The sensitivities and specificities of PPQ, APQ, and NHR for prediction of vocal nodules in children were 62.86% and 84.38%, 74.29% and 75.00%, and 31.43% and 93.75%, respectively. Discussion : The present findings suggest that vocal nodules affect vocal fold vibration, resulting in impaired control of pitch and loudness leading to increased noise components. NHR could be used to evaluate the efficacy of treatment, such as voice rehabilitation, in pediatric patients with vocal nodules because of its high specificity for prediction of vocal nodules in children.

The present findings suggested that in both patients, at the period of an increase of SPEV of the positional nystagmus with the shortening of its TC, cupulolithiasis transformed into canalolithiasis.","ja":"Changes in slow phase eye velocity (SPEV) and time constant (TC) of benign paroxysmal positional nystagmus in horizontal canal type were examined at transitional period from cupulolithiasis (apogeotropic nystagmus) into canalolithiasis (geotropic nystagmus) in two patients. SPEV and TC of positional nystagmus were tri-dimensionally analyzed. The first patient showed an apogeotropic nystagmus. Head rotation to the left in supine position induced a right-beating nystagmus with an initial SPEVof 15.3 degrees/s and a TC of 133 s. The nystagmus then gradually declined with a TC of 31.3 s after reaching a maximum SPEV of 28.8 degrees/s. After the nystagmus disappeared, he showed a geotropic nystagmus. The second patient showed a left-beating nystagmus with an initial SPEV of 2.5 degrees/s and a TC of 141 s when his head was rotated to the right in supine position. The nystagmus then gradually declined with a TC of 8.05 s after reaching a maximum SPEV of 16.7 degrees/s. After the nystagmus disappeared, he showed a geotropic nystagmus. The present findings suggested that in both patients, at the period of an increase of SPEV of the positional nystagmus with the shortening of its TC, cupulolithiasis transformed into canalolithiasis."},"publication_date":"2008-01","publication_name":{"en":"Acta Oto-Laryngologica","ja":"Acta Oto-Laryngologica"},"volume":"Vol.128","number":"No.1","starting_page":"22","ending_page":"28","languages":["eng"],"referee":true,"identifiers":{"doi":["10.1080/00016480701283752"],"issn":["0001-6489"]},"published_paper_type":"scientific_journal"}} {"insert":{"user_id":"B000344237","type":"published_papers"},"force":{"see_also":[{"@id":"https://web.db.tokushima-u.ac.jp/cgi-bin/edb_browse?EID=176862","label":"url"}],"paper_title":{"en":"眼振の3次元主軸解析による両側性後半規管BPPVの病態解明","ja":"眼振の3次元主軸解析による両側性後半規管BPPVの病態解明"},"authors":{"en":[{"name":"Takeda Noriaki"},{"name":"Satou Gou"},{"name":"Sekine Kazunori"},{"name":"今井 貴夫"}],"ja":[{"name":"武田 憲昭"},{"name":"佐藤 豪"},{"name":"関根 和教"},{"name":"今井 貴夫"}]},"publication_date":"2007","publication_name":{"en":"厚生労働省科学研究費補助金 特定疾患対策研究事業 前庭機能異常に関する調査研究 平成18年度報告書","ja":"厚生労働省科学研究費補助金 特定疾患対策研究事業 前庭機能異常に関する調査研究 平成18年度報告書"},"starting_page":"161","ending_page":"166","languages":["jpn"],"referee":true,"published_paper_type":"scientific_journal"}} {"insert":{"user_id":"B000344237","type":"published_papers"},"force":{"see_also":[{"@id":"https://web.db.tokushima-u.ac.jp/cgi-bin/edb_browse?EID=176861","label":"url"}],"paper_title":{"en":"前庭型メニエール病の臨床的検討","ja":"前庭型メニエール病の臨床的検討"},"authors":{"en":[{"name":"Takeda Noriaki"},{"name":"Sekine Kazunori"},{"name":"Satou Gou"}],"ja":[{"name":"武田 憲昭"},{"name":"関根 和教"},{"name":"佐藤 豪"}]},"publication_date":"2007","publication_name":{"en":"厚生労働省科学研究費補助金 特定疾患対策研究事業 前庭機能異常に関する調査研究 平成18年度報告書","ja":"厚生労働省科学研究費補助金 特定疾患対策研究事業 前庭機能異常に関する調査研究 平成18年度報告書"},"starting_page":"134","ending_page":"137","languages":["jpn"],"referee":true,"published_paper_type":"scientific_journal"}} {"insert":{"user_id":"B000344237","type":"published_papers"},"force":{"see_also":[{"@id":"https://web.db.tokushima-u.ac.jp/cgi-bin/edb_browse?EID=175241","label":"url"}],"paper_title":{"en":"当科における真珠腫性中耳炎の術式と術後聴力成績","ja":"当科における真珠腫性中耳炎の術式と術後聴力成績"},"authors":{"en":[{"name":"Satou Gou"},{"name":"Sekine Kazunori"},{"name":"Ando Masahiro"},{"name":"Jinnouchi Osamu"},{"name":"Toda Naoki"},{"name":"Abe Koji"},{"name":"Tamura Koichi"},{"name":"Takeda Noriaki"}],"ja":[{"name":"佐藤 豪"},{"name":"関根 和教"},{"name":"安藤 正裕"},{"name":"陣内 自治"},{"name":"戸田 直紀"},{"name":"阿部 晃治"},{"name":"田村 公一"},{"name":"武田 憲昭"}]},"publication_date":"2007","publication_name":{"en":"Otologia Fukuoka","ja":"耳鼻と臨床"},"volume":"Vol.53","number":"No.1","starting_page":"22","ending_page":"26","languages":["jpn"],"referee":true,"identifiers":{"doi":["10.11334/jibi1954.53.1_22"],"issn":["2185-1034"]},"published_paper_type":"scientific_journal"}} {"insert":{"user_id":"B000344237","type":"published_papers"},"force":{"see_also":[{"@id":"https://www.ncbi.nlm.nih.gov/pubmed/17011412","label":"url"},{"@id":"https://web.db.tokushima-u.ac.jp/cgi-bin/edb_browse?EID=160171","label":"url"}],"paper_title":{"en":"Natural history of benign paroxysmal positional vertigo and efficacy of Epley and Lemtert maneuvers","ja":"Natural history of benign paroxysmal positional vertigo and efficacy of Epley and Lemtert maneuvers"},"authors":{"en":[{"name":"Sekine Kazunori"},{"name":"Takao Imai"},{"name":"Satou Gou"},{"name":"Mahito Ito"},{"name":"Takeda Noriaki"}],"ja":[{"name":"関根 和教"},{"name":"Takao Imai"},{"name":"佐藤 豪"},{"name":"Mahito Ito"},{"name":"武田 憲昭"}]},"description":{"en":"We assessed the efficacy of Epley maneuver in patients with posterior canal benign paroxysmal positional vertigo (P-BPPV) and Lempert maneuver in patients with horizontal canal BPPV (H-BPPV).
