A Double-Edged Sword: Quality and Credibility of Colon Cancer Screening Content on YouTube.

Introduction Colorectal cancer (CRC) remains a significant public health challenge globally, with its pathogenesis involving the transformation of benign adenomas into malignant carcinomas. Despite advancements in screening and early detection significantly improving outcomes, the rise of digital platforms like YouTube for disseminating health information presents new challenges. Concerns over the accuracy and reliability of content underline the necessity for rigorous evaluation of these digital health education tools. Methods Our study was conducted at Nassau University Medical Center, East Meadow, New York. We meticulously analyzed YouTube videos on "colon cancer screening awareness," employing strict selection criteria to ensure both relevance and quality, focusing on English-language content with pertinent audio. Videos were evaluated for their quantitative and qualitative attributes-views, subscriber counts, likes/dislikes, comments, and content type, classifying them as scholarly or personal. We assessed video credibility through scientific accuracy using the DISCERN instrument, Global Quality Score (GQS), and Patient Education Materials Assessment Tool (PEMAT), ensuring consistency in quality and reliability evaluation among seven researchers via the intraclass correlation coefficient. These tools - DISCERN for assessing reliability and quality, GQS for evaluating overall quality, and PEMAT for understandability and actionability - facilitated a comprehensive evaluation framework. Our analysis, leveraging descriptive and inferential statistics, scrutinized differences in content quality between academic and private institutions, employing t-tests to identify statistically significant disparities. The study utilized Microsoft Excel (version 16.73, Microsoft Corporation, Redmond, Washington, United States) and IBM SPSS Statistics for Windows, version 29.0 (released 2022; IBM Corp., Armonk, New York, United States). for robust data processing and analysis, confirming the educational value and trustworthiness of the examined YouTube content. Results Our study of 156 YouTube videos on educational content, split between academic (68 videos) and private sources (88 videos), revealed significant quality differences. Using the DISCERN, PEMAT, and GQS metrics, academic videos consistently outperformed private ones, with significant margins: DISCERN (54.61 vs. 34.76), PEMAT (3.02 vs. 2.11), and GQS (3.90 vs. 2.02), supported by low p-values indicating a statistically significant superiority. These findings suggest that the source of content-academic versus private-plays a crucial role in determining the quality and reliability of educational materials on platforms like YouTube, highlighting the academic sector's commitment to higher educational standards. Conclusion The study emphasizes the critical role of credible sources in enhancing the quality of health education content on YouTube, particularly concerning CRC screening. The superiority of academic institutions in providing high-quality content suggests a need for viewers to critically assess the source of information. It also calls for enhanced regulatory oversight and measures to ensure the accuracy and reliability of health information online.

Undifferentiated Hepatic Sarcoma: A Rare Case.

Primary hepatic undifferentiated pleomorphic sarcoma (UPS) is a rare malignant mesenchymal tumor with a nonspecific clinical and radiologic presentation. Primary hepatic UPS is often a diagnosis of exclusion made by multiple immunohistological testing that rules out hepatic, hematologic, neural, and epithelial origin. Stains for mesenchymal origin are usually the only positive stain and do not demonstrate evidence of specific mesenchymal cell differentiation. We report a case of a 56-year-old male with no significant past medical history that presented with complaint of epigastric abdominal pain of six months duration. A computed tomography (CT) scan of the abdomen and pelvis exhibited numerous hepatic masses involving right and left hepatic lobe. A CT-guided core needle biopsy discovered undifferentiated/pleomorphic sarcoma. Histomorphology showed spindle cell neoplasm without recognizable hepatic tissue. Immunohistochemistry (IHC) stains were positive for smooth muscle actin (SMA) but failed to establish a more specific histogenesis. Furthermore, IHC stains revealed spindle neoplastic cells with focal and patchy positive h-caldesmon (approximately 10-15% of neoplastic cells), and negative for desmin. Given these results, the diagnosis of undifferentiated/pleomorphic sarcoma was established. It is imperative to consider UPS in the differential diagnosis of large liver lesions without evidence of differentiation. Early identification of this rare tumor can prevent the possibility of distant metastasis and improve survival among patients.

A Mass in the Thorax: A Rare Presentation of Gastrointestinal Stromal Tumor.

Gastrointestinal stromal tumors (GIST) can occur anywhere in the gastrointestinal tract, with the primary site being the stomach. GISTs are often discovered incidentally on imaging due to the non-specific symptoms they present at the presentation. They can be distinguished from other mesenchymal tumors by immunohistochemistry staining. These tumors can range from benign to highly malignant, with surgical resection as the main treatment modality. Here, we present a case of a large GIST found not in the stomach, but in the mediastinum, incidentally on imaging, in a middle-aged male.

A Rare Case of Extramedullary Plasmacytosis.

Plasmacytosis is the abnormal proliferation of plasma cells in tissue, bone, blood, or exudates. Mucous membrane plasmacytosis is a rare form of plasmacytosis that is usually idiopathic in nature. A 68-year-old female underwent a diagnostic and therapeutic esophagogastroduodenoscopy, which revealed a friable antral erythematous gastric fold and a gastric polyp. Subsequent pathological testing was positive for diffuse polyclonal plasma cell proliferation, which was suggestive of a gastric plasmacytosis. In this article, we report a rare presentation of mucous membrane plasmacytosis.

Leiomyoma in the Transverse Colon With Resection.

Benign proliferations of smooth muscle cells are known as leiomyomas; these proliferations can occur in the colon and are typically found incidentally. Colonic leiomyomas are very rare and are most commonly found in the descending or sigmoid colon. A 59-year-old Hispanic female presented to the gastroenterology clinic for surveillance colonoscopy. The biopsy showed a submucosal microscopic leiomyoma in the transverse colon. The treatment of choice for most colonic leiomyomas is surgical excision. This rare case favors the notion that endoscopic polypectomy may be superior to surgical excision, ultimately providing a less-invasive and less-costly procedure without complications or recurrence.
