Injection of botulinum toxin (Botox) into the laryngeal muscleshas become the treatment of choice for controlling the symptoms of spasmodic dysphonia (SD). Currently, no specific battery of objective tests to assess the outcome is universally accepted. The purpose of this study was to investigate demographic, clinical, and treatment factors with voice outcome following Botox injection. Sixty-eight patients with adductor SD who underwent at least one Botox injection during a 5-year period were studied. Voice outcome measures were made from patient self-reporting scales and included overall vocal quality, length of response, and duration of breathiness. Vocal quality was significantly correlated with the underlying severity of vocal symptoms prior to treatment, incidence of breathiness and unilateral versus bilateral injection. The length of response was greater in males and following bilateral injections. An increased period of breathiness significantly correlated with bilateral injections. 相似文献

Summary Ni(LH)3LX complexes (LH=hypoxanthine or xanthine; X=Cl, Br or I) are formed by boiling under reflux 2:1 molar mixtures of LH and hydrated NiX2 in HC(OEt)3–MeCO2Et. The new complexes appear to be linear chain-like polymers, characterized by bidentate monoanionic L– ligands singly bidging between adjacent Ni2+ ions. A coordination number six is attained by the presence of three terminal unidentate LH and one X ligand in the first coordination sphere of each Ni2+ ion. The neutral LH and monoanionic L– ligands bind exclusivelyvia ring nitrogens to NiII. The probable binding sites of the uni- and bi-dentate hypoxanthine and ligands in the new complexes are discussed.Presented in part at the 3rd Chem. Congress of North America (LH=xanthine) and the XXVI ICCC (LH=hypoxanthine), see refs. 1 and 2, respectively. 相似文献
