Comparison of narrow-band imaging with autofluorescence imaging for endoscopic detection of squamous cell carcinoma of the tonsil.

Purpose: Early detection of mucosal neoplastic lesions is crucial for a patient's prognosis. This has led to the development of effective optical endoscopic diagnostic methods such as narrow band imaging (NBI) and autofluorescence (AFI). Independent of each other, both of these methods were proven useful in the detection of mucosal neoplasias.

Which Epidemiological Characteristics Drive Decision Making in the Management of Patients with Vestibular Schwannoma?

The incidence of sporadic vestibular schwannoma has significantly increased over the past few decades. However, there is no method currently available to accurately predict the risk of subsequent tumor growth. The difference in the management of five patient groups has been evaluated: wait and scan, conversion to microsurgery, conversion to stereoradiotherapy, sterioradiotherapy, and microsurgery.

Head-shaking-induced nystagmus reflects dynamic vestibular compensation: A 2-year follow-up study.

Purpose: We aimed to assess the ability of a head-shaking test (HST) to reflect vestibular compensation in patients after unilateral peripheral vestibular loss and to provide missing evidence and new insights into the features of head-shaking-induced nystagmus (HSN) over a 2-year follow-up.

Background: HSN may occur after a prolonged sinusoidal oscillation of the head. HSN is frequently observed in subjects with vestibular function asymmetry; it usually beats toward the functionally intact or "stronger" ear and can be followed by a reversal of its direction.

Secretory carcinoma of salivary type in a lymph node presenting as a neck cyst diagnosed by cytology: A case report.

Secretory carcinoma (SC) is a relatively recently described salivary gland adenocarcinoma characterized by ETV6-NTRK3 gene fusion and, in most cases, indolent clinical behavior. Morphologically, the tumor shows a glandular architecture and the presence of monophasic tumor cells with vacuolated cytoplasm, low-grade nuclear atypia, and mucin production, with possibly a tubular, papillary, or cystic arrangement. In this article, we describe a case of a 52-year old man with SC involving a neck lymph node clinically manifesting as a slowly growing cystic neck mass without recent proof of the primary tumor, but with a history of a parotid gland "cystadenopapilloma," which had been removed 35 years prior.

Efficacy of Transnasal Flexible Videoendoscopy With Narrow Band Imaging for Follow-Up of Patients After Transoral Laser Cordectomy.

Background And Objectives: Transoral laser surgery is the optimal surgical treatment modality for the early stages of glottic cancer. To allow for further treatment to be as effective and as minimal as possible, persistent or recurrent tumors should be detected very soon. The main aim is to minimize the risk of necessity of performing a total laryngectomy.

[Endoscopic optical imaging methods in the diagnostics of the laryngeal cancer].

Endoscopic optical imaging methods for the detection of mucosal lesions in the ENT area have been developed for better and earlier detection of these changes. They can be divided into horizontal methods group - showing the surface of the mucous membrane (autofluorescence, photodynamic diagnosis, Narrow Band Imaging, magnifying and contact endoscopy) and vertical methods group - visualizing different layers of the mucosa (optical coherence tomography and confocal endomicroscopy). Some of them are routinely used in practice, others are used in experimental mode and their introduction into practice may be a matter of the near future.
