The usefulness of narrow-band Imaging (NBI) in nasopharyngeal lesions-Validation of the Ni NBI classification dedicated for vascular pattern in the nasopharynx.

Background: This study aims to explore the applicability of narrow-band imaging (NBI) involving the Ni classification for the diagnosis of nasopharyngeal mucosal lesions in order to distinguish malignant tumours (NPT) from non-malignant lesions.

Methods: Each patient (n = 53) with a suspected nasopharyngeal lesion underwent a trans-nasal flexible video endoscopy with an optical filter for NBI. We assessed the suspected area using white light imaging (WLI) in terms of location and morphology as well as the vascular pattern (using Ni classification of nasopharyngeal microvessels) and surrounding tissue by using NBI.

Vocal fold leukoplakia recurrence risk model.

The paper aims to define the variables that elevate the risk of VFL recurrence after adequate primary treatment, and to present the Recurrence Risk Model with practical conclusions to handle pVFL and rVFL. Out of 207 patients with primary vocal fold leukoplakia (pVFL), in 41 (19.8%) recurrent VFL (rVFL) was diagnosed.

Difficult glottis: Diagnostic dilemma in viewof the clinical presentation.

<br><b>Introduction:</b> The taxonomy of vocal fold lesions has been refined, and it serves as a common descriptive language for diagnosis, treatment algorithms, and reporting of outcomes. However, we observe rare cases when numerous pathologies overlap, resulting in an unclear and complicated clinical presentation of the glottis.</br> <br><b>Aim:</b> The aim of this paper is to present cases of overlapping etiopathological factors which poses a challenge when making a diagnosis and referring a patient for adequate treatment.

The importance of the gut microbiota in the promotion, development, and treatment outcomes of cancer with special regard to the gut-respiratory axis.

The role of oral and pharyngeal microbiota is important in the promotion and development of head and neck cancers, as discussed in detail in this publication. The object of this work is to gather scientific information on the importance of the gut- respiratory axis in the promotion, development, and treatment outcome of head and neck cancer (HNSCC). Scientific knowledge about the interaction of head and neck cancer tumor cells and gut microbiota is residual, so examples of the relationship between the gut microbiota and the promotion of development in cases of other malignancies are also discussed.
