The use of YouTube videos for educational purposes has been increasingly popular.The quality and accuracy of the information level of these videos should be checked by expert trainers. This study aims to evaluate the content, quality and functionality of YouTube videos on Histology and Embryology and to measure their educational usefulness. In the study, searches were performed using the keywords "Histology" and "Embryology" in the YouTube search tab. Quality and content were evaluated using the Video Power Index (VPI), modified DISCERN scale, JAMA and the Global Quality Scale (GQS). Videos were categorized by educational usefulness. SPSS software was used for statistical analysis. A statistically significant high correlation was observed between modified DISCERN scores and JAMA scores (r = 0.757, p < 0.001) and between modified DISCERN scores and GQS scores (r = 0.743, p < 0.001). A statistically significant high correlation was also determined between JAMA and GQS scores (r = 0.632, p < 0.001). GQS scores were weakly, negatively and significantly correlated with the number of comments (r = −0.302, p < 0.05) and dislikes (r = −0.325, p < 0.05).Based on GQS, the useful and non-useful videos differed significantly in terms of views, likes, dislikes, comments counts and days since upload (p < 0.05). Modified DISCERN and JAMA scores also differed significantly between the useful and nonuseful videos (p < 0.001). Educational videos published for Histology and Embryology education on the internet will be more beneficial if they are prepared by expert educators from reliable information sources, by the current literature, and by scoring systems such as DISCERN, JAMA and GQS.

Aim: Cisplatin is one of the effective antineoplastic drugs widely used in the treatment of many types of cancer. Cisplatin has harmful effects such as nephrotoxicity, ototoxicity and cardiomyopathy. Quercetin is an antioxidant of the flavonoid group. In this study, it was aimed to investigate the therapeutic effects of quercetin against cisplatin-induced kidney damage in rats. Materials and Methods: Twenty-eight male Wistar albino rats were randomly selected and divided into 4 groups: Group 1: Control (no application), Group 2: Quercetin (25 mg/kg/7 days/intraperitoneal), Group 3: Cisplatin (7 mg/kg/single dose/ intraperitoneal), Group 4: Cisplatin+quercetin (7 mg) /kg/single dose/ intraperitoneal cisplatin followed by 25 mg/kg/7 days/ intraperitoneal quercetin). After routine histological follow-up, hematoxylin eosin and periodic acid-schiff staining were performed. Histopathological damage score was calculated. Caspase-3 immunostaining was performed and scored. Results: Control and quercetin groups had normal histological appearance. In the cisplatin group, dilatation of the tubules, epithelial shedding, vacuolization of the tubular epithelial cells, and loss of microvilli in the proximal tubules were detected. In addition, infiltration areas were also found in places. In addition, an increase in caspase-3 immunostaining intensity was detected in this group (p=0.000). Histopathological findings were significantly reduced in the cisplatin+quercetin group compared to the cisplatin group (p=0.001). Conclusion:In this study, we think that quercetin is histopathologically beneficial in the treatment of cisplatin-induced kidney damage.

Tıpta uzmanlık tercih süreci, doğrudan ve dolaylı birçok değişkeni barındıran karmaşık ve dinamik bir süreçtir. Hekimlerin uzmanlık alan tercihlerini etkileyen faktörlerin araştırılması, bu eğitim ve öğretimi planlayanlar ve gelecekte uzmanlık alan tercihi yapacak olan hekimler için önem taşımaktadır. Bu çalışmada, tıpta uzmanlıkta Histoloji ve Embriyoloji'nin seçimini etkileyen faktörlerin öneminin tanımlanması amaçlanmıştır.Gereç ve Yöntem: Tanımlayıcı, kesitsel tipteki bu araştırmada, Histoloji ve Embriyoloji alanında uzmanlık eğitimi alan araştırma görevlilerine ve uzman hekimlere anket uygulandı. Toplam 108 katılımcı çalışmaya dahil edilerek, elde edilen verilerin istatistiksel analizi Statistical Package for the Social Sciences programı versiyon 22.0 ile yapıldı.Bulgular: Çalışmaya dahil edilen 108 katılımcının ortalama yaşı 35±9 yıl idi ve %64,8'i evliydi. Histoloji ve Embriyoloji alanında çalışan hekimlerin bu branşı seçmesini etkileyen faktörler incelendiğinde; %52,8 ile "kendine vakit ayırabilme", %48,10 ile nöbet sayısı/yoğunluğu, %46,30 hasta yoğunluğu, %41,7 ile icap sayısı, %38,9 ile şiddete maruz kalma ihtimali olduğu bulundu. Histoloji ve Embriyoloji alanında çalışan hekimlerin %38,89'u yurt dışında çalışmayı düşünürken, %50'si bu branştan istifa etmeyi düşünmekteydi. Mobbinge maruziyetin, istifa düşüncesini artırdığı görüldü.
