Impact of resection margin status and revision transoral laser microsurgery in early glottic cancer: analysis of organ preservation and local disease…

2022

Abstract Introduction Transoral laser microsurgery represents the treatment of choice for early glottic cancer. Its use and effectiveness are mainly related to laryngeal exposure and deep extension of tumor. Histopathologic assessment of surgical margin presents a main issue about transoral laser microsurgery and complete oncological excision. Objective The aim was to analyze the impact of revision surgery on organ preservation and local disease control in patients with early glottic cancer treated by transoral laser microsurgery. Methods We carried out a retrospective study on a cohort of 153 patients with early glottic cancer (Tis, T1, T2) treated by transoral laser microsurgery. Resectio…

CO(2)-laser treatment of laryngeal amyloidosis.

2003

Four consecutive female patients (age: 14–47 years) with laryngeal amyloidosis, treated with endoscopic CO2-laser surgery, entered the study. All patients underwent periodic microlaryngoscopies following surgery to confirm the adequacy of the surgical resection. Recurrences or suspected lesions were resected and fibrin deposits were removed to prevent the formation of synechiae or healing adhesions. After two negative microlaryngoscopies, performed two months apart, the patients were followed-up approximately every six months over a period from six months to 18 years, with no evidence of recurrences. The endoscopic CO2-laser technique is highly effective in the treatment of localized laryng…

Blutungen nach CO2-laserchirurgischer Tumorentfernung im HNO-Bereich

2004

Background: There are different reports in the literature how often postoperative hemorrhage occurs after laser resection of head-and-neck tumours. This retrospective study investigates the frequency of postoperative hemorrhage after laser surgery of head and neck tumours. Time and extent of bleeding have been considered as well as the localization of the primary tumour and possible general risk factors. Methods and Patients: Between 1998 and 2001, microscopic laser surgery was performed in 223 patients with previously untreated squamous cell carcinomas of the oral cavity, oropharynx, supraglottic and glottic region and the hypopharynx. In case of ultrasonographic or palpable evidence of ce…

Seasonal Mapping of Irrigated Winter Wheat Traits in Argentina with a Hybrid Retrieval Workflow Using Sentinel-2 Imagery

2022

Earth observation offers an unprecedented opportunity to monitor intensively cultivated areas providing key support to assess fertilizer needs and crop water uptake. Routinely, vegetation traits mapping can help farmers to monitor plant development along the crop’s phenological cycle, which is particularly relevant for irrigated agricultural areas. The high spatial and temporal resolution of the Sentinel-2 (S2) multispectral instrument leverages the possibility to estimate leaf area index (LAI), canopy chlorophyll content (CCC), and vegetation water content (VWC) from space. Therefore, our study presents a hybrid retrieval workflow combining a physically-based strategy with a machine learni…

Cómo los corpus pueden asistir a los estudiantes de traducción jurídica : la plataforma GENTT TransTools Corpora y Sketch Engine

2019

 
 Esta aportación analiza la aplicación de corpus a la enseñanza de la traducción jurídica en la educación superior utilizando la plataforma GENTT TransTools Corpora y Sketch Engine. En primer lugar, revisaremos la bibliografía sobre experiencias previas de aplicación de corpus textuales a la enseñanza de la traducción jurídica. A continuación, describiremos la experiencia de 10 años del grupo GENTT en el aula de traducción especializada, en la que hemos aplicado una metodología basada corpus y dirigida a promover la formación guiada y el aprendizaje constructivo y cooperativo. Estas experiencias sugieren que los corpus monolingües, multilingües y traducidos de textos especializados c…

Hypothesis of whiplike motion as a possible traumatizing mechanism in vocal fold vibration.

2003

The mucosal waves on the vibrating vocal folds may move in anterior-posterior, mediolateral and in caudal-cranial direction. This article discusses the possible significance of the vertical movement from the point of view of mechanical stress in phonation and the formation of vocal fold traumas. It is hypothesized that in certain conditions the vocal folds may behave in cranial direction like a quasi-free end of a long lash producing very rapid vibratory waves (e.g. the waves in a whiplash). This could be detrimental to the tissue structure. The role of phonation type in enhancing/diminishing this effect will also be discussed.

On stress production in whispered Finnish

1987

We have compared sentence stress production in normal phonation and whisper in two native speakers of Finnish using acoustical analysis, esophageal pressure measurements and electromyography. The average peak values of the fundamental frequency, intensity, esophageal pressure and the EMG recordings from the thyroarytenoid and cricothyroid muscles were measured and their intercorrelations were calculated. In normal speech the cricothyroid activity and the subglottal pressure showed a significant correlation with the peak values of the acoustical indicators of stress for both subjects. The thyroarytenoid muscle showed a statistically significant correlation with the fundamental frequency for …
