Purpose/Objective(s): Early stage supraglottic larynx cancers treated with definitive radiotherapy (RT) require treatment of the bilateral neck because of high rates of regional spread. Compared to older techniques, modern intensity modulated radiation therapy (IMRT) has been shown to precisely target tumor and draining nodal regions with the potential to spare organs at risk including those essential for prevention of aspiration. However, previous hospital-based studies have demonstrated decreased survival associated with the use of IMRT compared to 3D and 2D radiotherapy techniques in glottic larynx. We used the National Cancer Data Base (NC

Food and beverage marketing contributes to poor dietary choices among adults and children. As consumers spend more time on the Internet, food and beverage companies have increased their online marketing efforts. Studies have shown food companies' online promotions use a variety of marketing techniques to promote mostly energy-dense, nutrient-poor products, but no studies have compared the online marketing techniques and nutritional quality of products promoted on food companies' international websites. For this descriptive study, we developed a qualitative codebook to catalogue the marketing themes used on 18 international corporate websites associated with the world's three largest fast food and beverage companies (i.e. Coca-Cola, McDonald's, Kentucky Fried Chicken). Nutritional quality of foods featured on those websites was evaluated based on quantitative Nutrient Profile Index scores and food category (e.g. fried, fresh). Beverages were sorted into categories based on added sugar content. We report descriptive statistics to compare the marketing techniques and nutritional quality of products featured on the company websites for the food and beverage company websites in two high-income countries (HICs), Germany and the United States, two upper-middle-income countries (UMICs), China and Mexico, and two lower-middle-income countries (LMICs), India and the Philippines. Of the 406 screenshots captured from company websites, 67.8% depicted a food or beverage product. HICs' websites promoted diet food or beverage products/ healthier alternatives (e. g. baked chicken sandwich) significantly more often on their pages (25%), compared to LMICs (14.5%). Coca-Cola featured diet products significantly more frequently on HIC websites compared to LMIC websites. Charities were featured more often on webpages in LMICs (15.4%) compared to UMICs (2.6%) and HICs (2.3%). This study demonstrates that companies showcase healthier products in wealthier countries and advertise their philanthropic activities in lower income countries, which is concerning given the negative effect of nutrition transition (double burden of overnutrition and undernutrition) on burden of non-communicable diseases and obesity in lower income countries.

OBJECTIVE: To compare the intraoperative electrically evoked auditory brainstem response (EABR) morphologies between neurofibromatosis II (NF2) adult auditory brainstem implant (ABI) recipients who had auditory percepts post-operatively and those who did not and between NF2 adult ABI recipients and non-NF2 pediatric ABI recipients. METHODS: This was a retrospective case series at a single tertiary academic referral center examining all ABI recipients from 1994 to 2016, which included 34 NF2 adults and 11 non-NF2 children. The morphologies of intraoperative EABRs were evaluated for the number of waveforms showing a response, the number of positive peaks in those responses, and the latencies of each of these peaks. RESULTS: 27/34 adult NF2 patients and 9/10 children had EABR waveforms. 20/27 (74.0%) of the adult patients and all of the children had ABI devices that stimulated post-operatively. When comparing the waveforms between adults who stimulated and those who did not stimulate, the proportion of total number of intraoperative EABR peaks to total possible peaks was significantly higher for the adults who stimulated than for those who did not (p < 0.05). Children had a significantly higher proportion of total number of peaks to total possible peaks when compared to adults who stimulated (p < 0.02). Additionally, there were more likely to be EABR responses at the initial stimulation than intraoperatively in the pediatric ABI population (p = 0.065). CONCLUSIONS: The value of intraoperative EABR tracing may lie in its ability to predict post-operative auditory percepts based on the placement of the array providing the highest number of total peaks.

OBJECTIVES:To describe the epidemiology and analyze factors determinant of survival in patients with oropharyngeal lymphoma, using the Surveillance Epidemiology and End Results (SEER) database. METHODS:2504 patients with oropharyngeal lymphoma were identified using the most recent SEER database entry from 1976 to 2016. Demographic information, Ann Arbor stage, tumor histopathology and location were collected. Multivariate analysis was used to analyze patient and tumor characteristics associated with survival. RESULTS:The mean age of the patients studied was 60.5years, 58.4% of the subjects were male and 81% were white. Diffuse large B cell lymphoma (DLBCL) was the most common histologic subtype involving 56.9% of cases. The most common subsite of origin was the tonsil, with 71% of lymphomas originating from there. The association of survival with stage, age, tumor location, presence of B symptoms, tumor pathology, gender and race was analyzed using multivariate regression. Decreased survival was significantly associated with patient age p<0.0001, Ann Arbor staging p=0.005, the presence of B symptoms p=0.003 and tumor histopathology (T cell tumors) p=0.01. Patients with tumors originating from the soft palate were significantly more likely to die asa result of their disease p=0.03. CONCLUSION:Oropharyngeal lymphoma most commonly originates from the tonsil. DLBCL is the most common subtype and has a good prognosis. The presence of B symptoms, tumors originating from the soft palate and patients with T cell tumors have the worst prognosis. This information can potentially be of great utility to the head and neck surgeon discussing prognosis with patients suffering from oropharyngeal lymphoma.
