Objectives/Hypothesis: Severe vocal fold lesions such as vocal fold sulcus, scars, and atrophy induce a communication disorder due to severe hoarseness, but a treatment has not been established. Basic fibroblast growth factor (bFGF) therapies by either four-time repeated local injections or regenerative surgery for vocal fold scar and sulcus have previously been reported, and favorable outcomes have been observed. In this study, we modified bFGF therapy using a single of bFGF injection, which may potentially be used in office procedures.Study Design: Retrospective chart review. Methods: Five cases of vocal fold sulcus, six cases of scars, seven cases of paralysis, and 17 cases of atrophy were treated by a local injection of bFGF. The injection regimen involved injecting 50 mg of bFGF dissolved in 0.5 mL saline only once into the superficial lamina propria using a 23-gauge injection needle. Two months to 3 months after the injection, phonological outcomes were evaluated.Results: The maximum phonation time (MPT), mean airflow rate, pitch range, speech fundamental frequency, jitter, and voice handicap index improved significantly after the bFGF injection. Furthermore, improvement in the MPT was significantly greater in patients with (in increasing order) vocal fold atrophy, scar, and paralysis. The improvement in the MPT among all patients was significantly correlated with age; the MPT improved more greatly in younger patients.Conclusions: Regenerative treatments by bFGF injection-even a single injection-effectively improve vocal function in vocal fold lesions.
Abstract. In this study we investigated the combined effects of docetaxel and d-allose in HSC3 human oral carcinoma cells. The dose enhancement ratios at the 25% survival level were 1.3 and 1.71 for combined treatment with 10 or 25 mM d-allose, respectively. Apoptosis was significantly increased by addition of d-allose. Additionally, a synchronous increase in the G 2 /M-phase population was observed after docetaxel plus d-allose treatment. In vivo experiments revealed that docetaxel plus d-allose was more effective than either agent alone. Thus, d-allose enhanced the anticancer effects of docetaxel, and combined treatment may be useful to achieve clinical efficacy with reduced toxicity.
Under all anesthesia protocols, the vocal cords of most patients could be positioned such that the best vocal outcome could be expected. Statistical analyses demonstrated improved maximum phonation time and mean airflow rate, and grade, roughness, breathiness, asthenia, and strain (GRBAS) scale in all patients, regardless of their anesthesia protocol. Furthermore, of the three protocols, local anesthesia had the shortest operation time.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
