This study was conducted to evaluate the performance and reach of YouTube videos on physical examinations made by Spanish university students. We analyzed performance metrics for 4 videos on physical examinations in Spanish that were created by medical students at Miguel Hernández University (Elche, Spain) and are available on YouTube, on the following topics: the head and neck (7:30), the cardiovascular system (7:38), the respiratory system (13:54), and the abdomen (11:10). We used the Analytics application offered by the YouTube platform to analyze the reach of the videos from the upload date (February 17, 2015) to July 28, 2017 (2 years, 5 months, and 11 days). The total number of views, length of watch-time, and the mean view duration for the 4 videos were, respectively: 164,403 views (mean, 41,101 views; range, 12,389 to 94,573 views), 425,888 minutes (mean, 106,472 minutes; range, 37,889 to 172,840 minutes), and 2:56 minutes (range, 1:49 to 4:03 minutes). Mexico was the most frequent playback location, followed by Spain, Colombia, and Venezuela. Uruguay, Ecuador, Mexico, and Puerto Rico had the most views per 100,000 population. Spanish-language tutorials are an alternative tool for teaching physical examination skills to students whose first language is not English. The videos were especially popular in Uruguay, Ecuador, and Mexico.

OBJECTIVE: Patients with endometriosis are at increased risk of ovarian cancer. It has been suggested that atypical endometriosis is a precursor lesion of endometriosis-associated ovarian cancer (EAOC). The aim of this study is to evaluate if cytologic (cellular) atypia and architectural atypia (hyperplasia), histologic findings described as atypical endometriosis, play a different role in patients with EAOC. METHODS: A prospective study was conducted between January 2014 and April 2017 at our institution with patients undergoing surgery with a histologic diagnosis of endometriosis, ovarian cancer, or EAOC. The prevalence and immunohistologic study (Ki-67, BAF250a, COX-2) of cases of cellular and architectural atypia in endometriosis were analyzed. RESULTS: Two hundred and sixty-six patients were included: the diagnosis was endometriosis alone in 159 cases, ovarian cancer in 81, and EAOC in 26. Atypical endometriosis was reported in 23 cases (12.43%), 39.13% of them found in patients with EAOC. Endometriosis with cellular atypia was found mainly in patients without neoplasm (71.4%), and endometriosis with architectural atypia was seen in patients with ovarian cancer (88.9%) (p=0.009). Ki-67 was significantly higher in endometriosis patients with architectural atypia than those with cellular atypia. CONCLUSION: The diagnosis of endometriosis with architectural atypia is important because it may be a precursor lesion of ovarian cancer; therefore, pathologists finding endometriosis should carefully examine the surgical specimen to identify any patients with hyperplasia-type endometriosis, as they may be at higher risk of developing EAOC.
