Recent investigations by our study team have demonstrated patients using gabapentin for pain management during chemoradiotherapy (CRT) do well maintaining swallowing during treatment with less need for narcotic pain medication, PEG dependence, weight loss, and short-term swallowing morbidity. The purpose of this investigation was to characterize the long-term swallowing function of these patients 1-year following treatment. Sequential patients receiving CRT for oropharyngeal cancer and concurrent gabapentin were evaluated 1-year following treatment for swallowing outcomes...

BACKGROUND: Chin-up posture is frequently used to manage oral dysphagia after head and neck cancer. This prospective study investigates the effects of chin-ups on the sequence of pharyngeal swallowing events. METHODS: Twelve healthy young adults performed 45 consecutive swallows of 5 mL water across 3 phases on videofluoroscopy: 5 swallows in the neutral head position; 30 swallows during chin-up posture; and 10 swallows in the neutral head position. Swallowing kinematic and bolus flow measures for 9 swallowing events were recorded...

A major cause of morbidity and mortality in patients with cancer is infection. Since the introduction of the Haemophilus influenzae type b (Hib) vaccine in the United States in the 1990s, invasive H influenzae infection has become less common. We report on 5 patients with cancer and invasive H influenzae infection. A literature review was also performed of the dominant Haemophilus subtype and the clinical features associated with the infection and concomitant cancer. Of the 17 cases found in the literature, had hematological malignancies and 1 case each had thymoma, schwannoma, teratoma, and pancreatic, Merkel cell, pharyngeal, laryngeal, and rectal carcinomas...

Aims. In order to determine the indications of transoral surgery for a tumor located at the pharyngoesophageal junction, the trumpet maneuver with transnasal endoscopy was used. Its efficacy is reported here. Material and Methods. An 88-year-old woman complaining of dysphagia, diagnosed with cervical esophageal cancer, and hoping to preserve her voice and swallowing function was admitted to our hospital. Conventional endoscopy showed that the tumor had invaded the hypopharynx. When inspecting the hypopharynx and the orifice of the esophagus, we asked the patient to blow hard and puff her cheeks with her mouth closed (trumpet maneuver)...

The superior laryngeal artery is the principal artery supplying the laryngeal mucosa, musculature, and glands. Knowledge of variations in the origin of superior laryngeal artery could prove to be very useful during reconstructive surgeries of the larynx, partial laryngectomy, laryngeal transplantation, and also during procedures like super-selective intra-arterial chemotherapy for laryngeal and hypolaryngeal cancers. However, relatively few studies have been done on the superior laryngeal artery in comparison to its clinical importance...

Common cutaneous human papillomavirus (HPV) types induce skin warts, whereas species beta HPV are implicated, together with UV-radiation, in the development of non-melanoma skin cancer (NMSC) in immunosuppressed patients. Licensed HPV vaccines contain virus-like particles (VLP) self-assembled from L1 major capsid proteins that provide type-restricted protection against mucosal HPV infections causing cervical and other ano-genital and oro-pharyngeal carcinomas and warts (condylomas), but do not target heterologous HPV...

PURPOSE: To develop a swallowing prediction system (SPS) using force sensing sensors and evaluate its feasibility. METHODS: The SPS developed consists of force sensing sensor units, a thermoplastic mask, a signal transport device and a control PC installed with an in-house software. The SPS is designed to predict the pharyngeal stage of swallowing because it is known that internal organ movement occurs in pharyngeal stage. To detect prediction signal in the SPS, the force sensing sensor units were attached on both the submental muscle region and thyroid cartilage region of the thermoplastic mask...

OBJECTIVES: Aspiration pneumonia is an under-reported treatment sequelae following radiotherapy for head and neck cancer (HNC) patients. This study aims to investigate its incidence and risk factors in this population. MATERIALS AND METHODS: A retrospective review of all HNC patients that had received radiotherapy or chemo radiotherapy with radical intent at a single institution was undertaken (n=206). Dose delivered to the pharyngeal constrictors, base of tongue and cricopharyngeus was calculated and compared between those patients who had died from aspiration pneumonia and those who are alive or had died from other causes...

The popularity of electronic cigarettes (ECs) is rapidly growing and ECs are claimed to be an uncritically regarded alternative to conventional cigarettes. The mucosal tissue of the upper aerodigestive tract (UADT) is the first contact organ for xenobiotics such as liquids of ECs. The aim of this study is to investigate the bimolecular effects of e-liquids on human pharyngeal tissue cultures to evaluate whether e-liquids and their components present a risk factor for head and neck squamous cell carcinoma. Fresh tissue samples of healthy oropharyngeal mucosa were assembled into mucosal tissue cultures...

PURPOSE: Human papillomavirus (HPV) 16 plays an etiologic role in a growing subset of HNSCCs, where viral expression of the E6 and E7 oncoproteins are necessary for tumor growth and maintenance. Although patients with HPV(+) tumors have a more favorable prognosis, there are currently no HPV-selective therapies. Recent studies identified differential receptor tyrosine kinase (RTK) profiles in HPV(+) vs. HPV(-) tumors. One such RTK, HER3, is overexpressed and interacts with phosphoinositide 3-kinase (PI3K) in HPV(+) tumors...

BACKGROUND: The robust desmoplasia associated with head and neck squamous cell carcinoma (HNSCC) suggests that the tumor microenvironment may be an important component in the pathophysiology of this cancer. Moreover, the high recurrence rate and poor clinical response to chemotherapy and radiation treatment further underscores that the non-cancerous cells of the microenvironment, such as mesenchymal stromal cells (MSCs), cancer associated fibroblasts (CAFs), and pericytes, may be important in the pathophysiology of HNSCC...

Specific human papillomavirus genotypes are associated with most ano-genital carcinomas and a large subset of oro-pharyngeal carcinomas. Human papillomavirus DNA is thus a tumour marker that can be detected in the blood of patients for clinical monitoring. However, data concerning circulating human papillomavirus DNA in cervical cancer patients has provided little clinical value, due to insufficient sensitivity of the assays used for the detection of small sized tumours. Here we took advantage of the sensitive droplet digital PCR method to identify circulating human papillomavirus DNA in patients with human papillomavirus-associated carcinomas...
