BACKGROUND Helicobacter pylori is known to cause gastric cancer. Presence and carcinogenicity in the upper aerodigestive system is doubtful. This study examined the prevalence of Helicobacter pylori and related factors in biopsies from the upper aerodigestive tract (UADT) in patients with gastric colonization by Helicobacter pylori. METHODS In a case series study, 26 patients with histopathol...

This study is a systematic review of the literature that was performed to clarify the natural history and treatment outcomes of upper aerodigestive tract metastases from cutaneous melanoma. A search of the MEDLINE database was undertaken from 1950 to 2013 to identify relevant manuscripts for this review. Article inclusion required cases with documentation of previous cutaneous melanoma primary ...

OBJECTIVES/HYPOTHESIS Visualization by endoscopy is essential in the diagnosis of upper aerodigestive tract lesions. Recent studies showed that narrow band imaging (NBI) increases the diagnostic potential of conventional white light imaging (WLI) by highlighting the superficial vessels. The objective of this study was to evaluate whether the use of NBI would influence inter- and intraobserver a...

As one of the minimally invasive surgeries (MIS), transoral robotic surgery (TORS) contributes to excellent oncological and functional outcomes. This paper introduces a compliant flexible system for surgery, consisting an execution part with parallel mechanisms positioning continuum structure. A pilot cadaveric study that mimics procedure TORS using intact human head was conducted evaluate feas...

Five patients with upper aerodigestive tract pathology seen acutely in the Accident and Emergency department at St Mary's Hospital, London are presented. The value of the lateral soft tissue neck X-ray in their diagnosis is discussed.

INTRODUCTION We present a retrospective study series and discussion of the current literature to discuss the management of fishbones in the upper aerodigestive tract. MATERIALS AND METHODS From January 2013 to July 2016, all patients referred to our referral center because of a fishbone in the upper aerodigestive tract were analysed. RESULTS Of the 24 patients, 95% of them reported discomfo...

BACKGROUND Multiple primary upper aerodigestive tract carcinomas can occur in up to 15% of patients. We have shown previously that half of the patients with multiple upper aerodigestive tract squamous cell carcinomas are initially seen with synchronous tumors. Most metachronous squamous cell carcinomas become manifest within 3 years. OBJECTIVE To examine the expression of 2 proteins-cyclin D1...

Though lipomas are very common tumors occurring in the head and neck region, there are very few case reports of submucosal lipomas of the upper aerodigestive tract. A case of myxoid lipoma of the supraglottic region is reported.
