Background: The incidence of human papillomavirus- (HPV-) related oropharyngeal squamous cell carcinoma (OPSCC) has been rapidly increasing worldwide. HPV is reported in approximately 50% cases of OPSCC in Japan. However, there are few reports of synchronous bilateral HPV-positive tonsillar carcinoma, and, in almost all those cases, carcinoma was detected using positron emission tomography/computed tomography and/or bilateral tonsillectomy. Methods and Results: We report the case of a 63-year-old male with bilateral tonsillar carcinoma detected using transoral endoscopic examination with narrow-band imaging (NBI)...

PURPOSE: In a previous pilot study we observed that intra-operative narrow-band imaging (NBI) helps achieve clear superficial resection margins. The aim of this study was to verify if the use of intra-operative NBI can help to obtain tailored resections and if it is influenced by the lesion site, aspects not investigated in our previous study. MATERIALS AND METHODS: The resection margins of 39 oral and 22 oropharyngeal squamous cell carcinomas were first set at 1...

Demographic developments and medical progress will cause the already high prevalence of swallowing disorders to increase further in the future. With the same number of specialists and economic resources, it is necessary to improve the efficiency of dysphagia diagnostics and continue to offer patients a treatment concept tailored to their needs. Manifold and often co-existing causes of dysphagia require interdisciplinary cooperation in this area. Endoscopic swallowing diagnostics play a prominent role in dysphagia diagnostics and should always contain thorough endoscopy of the upper aerodigestive tract-the domain of the ENT specialist and phoniatrician...

White light cystoscopy (WL) is the gold standard for the detection of bladder cancer. It can be performed using a rigid or flexible urethrocystoscope. With the more recent introduction of high definition (HD) techniques, WL cystoscopy has been decisively improved. Supplementary optical techniques are also used to improve the detection of bladder cancer. Among these are photodynamic diagnosis (PDD), narrow-band imaging (NBI), S‑technologies of IMAGE1 S, optical coherence tomography (OCT), confocal laser endomicroscopy (CLE), and Raman spectroscopy...

The basolateral nucleus of the amygdala (BLA) plays a key role in processing stressful events and affective disorders. Previously we have documented that exposure of chronic forced swim (FS) to rats produces a depressive-like behavior and that sensitization of BLA neurons is involved in this process. In the present study, we demonstrated that chronic FS stress (CFSS) could activate corticotrophin-releasing factor (CRF)/CRF receptor type 1 (CRFR1) signaling in the BLA, and blockade of CRF/CRFR1 signaling by intra-BLA injection of NBI27914 (NBI), a selective CRFR1 antagonist, could prevent the CFSS-induced depressive-like behaviors in rats, indicating that activation of CRF/CRFR1 signaling in the BLA is required for CFSS-induced depression...

The advent of the endoscope has facilitated otological surgery in recent years. Advances in optical technology have led to the development of high definition visualisation, such as 4K magnification. Narrow band imaging (NBI) has been shown to improve visualisation of tissue based on varying degrees of vascularity. This is a feasibility study, the first of its kind, aiming to investigate the appearances of middle ear anatomy and pathology (tympanic membrane, tympanosclerosis, cholesteatoma, granulation, endolymphatic sac hydrops, otosclerosis) under the NBI filter, using a high definition 4K endoscope...

BACKGROUND & AIMS: Narrow-band imaging (NBI) is an image-enhanced form of endoscopy used to observed microstructures and capillaries of the mucosal epithelium that allows for real-time prediction of histologic features of colorectal polyps. However, NBI expertise is required to differentiate hyperplastic from neoplastic polyps with high levels of accuracy. We developed and tested a system of computer-aided diagnosis with a deep neural network (DNN-CAD) to analyze narrow-band images of diminutive colorectal polyps...

BACKGROUND AND AIMS: Patients with longstanding ulcerative colitis (UC) are at increased risk of developing colorectal neoplasia. Chromoendoscopy (CE) increases detection of lesions, and Kudo pit pattern classification I and II have been suggested to be predictive of benign polyps in UC. Little is known on the use of this classification in non-magnified high-definition (HD) (virtual) CE and narrow-band Imaging (NBI), or on the interobserver agreement. The aim of this pilot study was to assess the diagnostic accuracy and the interobserver agreement of the Kudo pit pattern classification in UC patients undergoing surveillance with methylene blue CE or NBI in a multicenter study...

BACKGROUND: Studies have confirmed an increased risk of colorectal cancer in patients with ulcerative colitis; hence, surveillance is recommended. Optional modalities include white light endoscopy (WLE) or dye-spray chromoendoscopy. However, narrow-band imaging (NBI) is still not considered comparable to chromoendoscopy. AIM: The aim of this study was to compare the diagnostic yield (DY) of WLE, chromoendoscopy, NBI for detection of neoplasia in patients with inflammatory bowel disease (IBD) by performing a meta-analysis of the existing literature...

BACKGROUNDS: Magnifying endoscopy with blue laser imaging (ME-BLI) for diagnosis of early gastric cancer (EGC) is as effective as magnifying endoscopy with narrow-band imaging (ME-NBI). However, there are different EGCs in microstructure visualization between ME-BLI and ME-NBI. This study aimed to clarify the pathological features of the EGCs, in which microstructure visualization was different between ME-NBI and ME-BLI. METHODS: EGCs were classified into groups A (irregular microsurface pattern (MSP) in ME-BLI and absent MSP in ME-NBI), B (irregular MSP in two modalities), or C (absent MSP in two modalities), according to the vessel plus surface classification...

More than half of primary lung cancers are not resectable at diagnosis and 40% of deaths may be secondary to loco-regional disease. Many of these patients suffer from symptoms related to airways obstruction. Indications for therapeutic endoscopic treatment are palliation of dyspnea and other obstructive symptoms in advanced cancerous lesions and cure of early lung cancer. Bronchoscopic management is also indicated for all those patients suffering from benign or minimally invasive neoplasm who are not suitable for surgery due to their clinical conditions...
