“…No current publication exists on histological verification of newly proposed guidelines of vascular changes in the vocal cords by ELS. Schossee discovered that significantly more changes can be detected by NBI in comparison to white light endoscopy with respect to longitudinal vessel changes [ 14 ].…”

A newly proposed classification by the European Laryngological Society (ELS) of glottic lesions by narrow-band imaging (NBI) divides their vascular patterns into longitudinal and perpendicular ones. The latter are further subdivided into the wide and narrow patterns. The longitudinal, wide, and narrow patterns are characteristic of benign disease, papilloma, and malignancy, respectively. The aim of the study was to investigate the diagnostic effectiveness of the classification. Forty patients with glottic lesions underwent microlaryngoscopy. The vascular patterns of all vocal cords were defined with NBI. The affected vocal cords were histologically analysed and comprised the arm (A). Unaffected vocal cords were not histologically analysed but followed-up and comprised the arm (B) and were regarded as true negatives if no suspicious changes appeared during the follow-up. The vocal cords from the arm A were categorised into the benign and malignant group according to the histologic result. The ratio of vascular patterns was determined and the groups were statistically compared using the Chi-square test and Fisher’s exact test. Perpendicular changes were observed in 36.6% (9/26) of benign diseases and in 100% (23/23) of cancer conditions (p < 0.001). Wide perpendicular changes appeared only in papillomas (6/6) while narrow ones mostly in malignancies (23/26) and also in benign conditions (3/26) (p < 0.001). The sensitivity, specificity, positive and negative predictive values, and accuracy were 100, 95, 88, 100 and 96%, respectively. The new ELS classification can be used effectively and safely to differentiate malignant from benign disease.

“…Each of its solutions is the position where the error occurs. erefore, to realize the grammar error correction function, the error polynomial equation must be obtained first and this mode does not need to support other parallel modes, or even serial mode, like the companion computing [16]. At the same time, after the money search retrieves the wrong location, it will…”

English grammar error correction algorithm refers to the use of computer programming technology to automatically recognize and correct the grammar errors contained in English text written by nonnative language learners. Classification model is the core of machine learning and data mining, which can be applied to extracting information from English text data and constructing a reliable grammar correction method. On the basis of summarizing and analyzing previous research works, this paper expounded the research status and significance of English grammar error correction algorithm, elaborated the development background, current status, and future challenges of the classification model, introduced the methods and principles of feature extraction method and dynamic residual structure, constructed a basic model for English grammar error correction based on the classification model, analyzed the classification model and translation model of English grammar error correction, proposed the English grammar error correction algorithm based on the classification model, performed the analyses of the model architecture and model optimizer of the grammar error correction algorithm, and finally conducted a simulation experiment and its result analysis. The study results show that, with the continuous increase of training samples and the continuous progress of learning process, the proposed English grammar error correction algorithm based on the classification model will continue to increase its classification accuracy, further refine its recognition rules, and gradually improve correction efficiency, thereby reducing processing time, saving storage space, and streamlining processing flow. The study results of this paper provide a certain reference for the further research on English grammar error correction algorithm based on the classification model.

“…Die geschätzte Überlegenheit von NBI bei der Beurteilung der Schleimhaut ist laut Literatur größtenteils auf die optimierte Kontrastierung der pathologischen Läsionen und der oberflächlichen Gefäßformationen zurückzuführen. Die im Vergleich zum Weißlichtbild deutliche Konturanhebung ist subjektiv als auch objektiv validiert worden [15,16].…”

Modern endoscopic imaging techniques make it possible to detect tumor diseases of the upper respiratory and digestive tract and treat them minimally invasive - with a good oncologic outcome and maintaining the functionality of the tissue.Horizontal techniques permit the inspection of big mucous membrane surfaces, searching vor areas suspicious of dysplasia or tumor. They can be used as screening techniques. Vertical techniques serve for precise examination of in-depth expansion, infiltration chraracteristics and dignity of known lesions. Cellular techniques deal with the detection of cellular changes in vivo. As the techniques have different advantages and disandvantages, it is recommended to combine several techniques for best diagnostic gains.
