Assessing the Quality of Patient Information for Cholesteatoma on the Video Sharing Platform YouTube.

INTRODUCTION: Cholesteatoma is common chronic ear condition that usually requires surgical treatment and long-term follow-up. The Internet helps patients find information about their medical conditions and assists in shared clinical decision making. This work aims to assess the quality of information on YouTube for cholesteatoma. We aim to assess the quality of the most popular cholesteatoma videos on YouTube using recognized scoring systems and determine if quality correlated with video likes and views. METHODS: The YouTube website was systematically searched on separate days with a formal search strategy to identify videos relevant to cholesteatoma. Each video was viewed and scored by three independent assessors using a novel Essential and Ideal Video Completeness criteria for cholesteatoma and the validated DISCERN tool. Popularity metrics were analyzed and compared with video popularity. RESULTS: A total of 90 YouTube videos were analyzed with an average 55,292 views per video with an average of 271 likes and 22 dislikes. The interrater correlation was moderate with Fleiss kappa score 0.42 ( p < 0.01) using the Essential and Ideal Video Completeness criteria for cholesteatoma and interrater correlation coefficient was 0.78 (95% confidence interval, 0.58-0.90), indicating good reliability for DISCERN scores. The overall video quality was poor with higher DISCERN scores found from academic institutions. CONCLUSION: YouTube content with regard to cholesteatoma is of poor quality. Videos with unclassified sources or more dislikes correlated with poor quality. Otology societies should be encouraged to publish high-quality YouTube videos on cholesteatoma and other ear conditions.

Inulin coated Mn3O4 nanocuboids coupled with RNA interference reverse intestinal tumorigenesis in Apc knockout murine colon cancer models.

This study reports the development and pre-clinical evaluation of biodrug using RNA interference and nanotechnology. The major challenges in achieving targeted gene silencing in vivo include the stability of RNA molecules, accumulation into pharmacological levels, and site-specific targeting of the tumor. We report the use of Inulin for coating the arginine stabilized manganese oxide nanocuboids (MNCs) for oral delivery of shRNA to the gut. Furthermore, bio-distribution analysis exhibited site-specific targeting in the intestines, improved pharmacokinetic properties, and faster elimination from the system without cytotoxicity. To evaluate the therapeutic possibility and effectiveness of this multimodal bio-drug, it was orally delivered to Apc knockout colon cancer mice models. Persistent and efficient delivery of bio-drug was demonstrated by the knockdown of target genes and increased median survival in the treated cohorts. This promising utility of RNAi-Nanotechnology approach advocates the use of bio-drug in an effort to replace chemo-drugs as the future of cancer therapeutics.

The incidence of squamous cell carcinoma of the oral tongue is rising in young non-smoking women: An international multi-institutional analysis.

PURPOSE: Increasing evidence is accumulating for an alarming rising incidence of oral tongue SCC in a younger cohort, particularly in developed countries. The aim of this study is to analyse the change in incidence of OSCC in patients under the age of 45 in developed nations in the Asia-Pacific region. PATIENTS AND METHODS: Population data was extracted from the Australian Cancer Incidence and Mortality 2017 database and National Registry of Diseases Office, Singapore to allow calculation of the incidence in the Australian and Singaporean populations. This was compared to multi-institutional data from four tertiary Australian institutions. The inclusion criteria were as follows: a) diagnosis of primary SCC of the mobile tongue; b) treatment with curative intent; c) complete histopathologic data; d) complete adjuvant treatment data; e) follow up data. RESULTS: Analysis of ACIM data demonstrated that there was a significant increase in the incidence of tongue SCC in those under the age of 45 in the Australian and Singaporean populations (p < 0.001). When analysed for gender, the incidence of tongue SCC increased at a significantly higher rate in females than males (p < 0.001). Similarly, in the multi-institutional analysis including 1814 patients, the number of females under the age of 45 with tongue SCC significantly increased over time (p < 0.001), with the proportion of smokers in this cohort decreasing over time. CONCLUSION: The incidence of tongue SCC is rising in young females in developed nations in the Asia Pacific region, in keeping with observed epidemiological trends worldwide.

Organ Preservation Protocols in T4 Laryngeal Cancer: a Review of the Literature.

Population-based studies indicate that chemoradiation has become the most popular treatment for advanced laryngeal cancers; however, by extrapolating trial results to the general population, several issues have emerged, such as reduced overall survival, non-functional laryngeal preservation, and poor response to treatment. Although included in these trials, T4 laryngeal and hypopharyngeal cancers with cartilage invasion formed a small percentage of these patients and questions over whether they were appropriately staged remain unanswered. Literature on the use of chemoradiation in this set of patients, including the challenges, treatment considerations, and factors predicting response to treatment and outcomes, was reviewed. Current evidence indicates that all patients of T4 laryngeal and hypopharyngeal cancer are not suitable candidates for organ preservation; this modality should be offered only to select patients with good performance status and access to rehabilitative care and regular follow-up in order to achieve good results.
