RESUMO
Introduction Learning methodologies, particularly in medical education, are evolving with the integration of internet-based technologies into daily life. As a platform, YouTube has become a significant tool for studying human anatomy among medical students. This study aims to assess the utilization of YouTube in learning human anatomy, the types of audio-visual materials used, and the platform's perceived effectiveness in understanding and memorizing anatomical information. Methods A cross-sectional questionnaire study was conducted among 200 medical students at a medical college over one year, of whom 195 completed the questionnaire and were included. The questionnaire addressed general YouTube usage, specific usage for medical studies and human anatomy, types of audio-visual materials used, and the perceived effectiveness of YouTube in understanding and memorizing anatomical information. Data were analyzed using IBM SPSS Statistics for Windows, Version 25.0 (IBM Corp., Armonk, NY) for Pearson's chi-square test to determine statistical differences based on gender and year of study. Results The study cohort comprised 195 medical students (average age: 19.8±1.1 years), 62.6% females and 37.4% males. YouTube emerged as extensively utilized, with 94.5% of males and 96.7% of females reporting general usage and 91.8% of males and 89.3% of females utilizing it for medical studies. For human anatomy learning, 93.2% of males and 89.3% of females relied on YouTube. Among the audio-visual materials, PowerPoint presentations were most prevalent, favored by 46.5% of males and 41.8% of females. Regarding effectiveness, 82.1% of males and 83.7% of females affirmed YouTube's enhancement of anatomical understanding, with 89% of males and 85.3% of females acknowledging its aid in memorization. Additionally, 90.4% of males and 87.3% of females recommended YouTube as an anatomy learning tool. Despite observed gender-based preferences for specific content types, no statistically significant differences were discerned in YouTube's usage and perception across genders. Conclusions YouTube is a widely used and effective tool for the study of human anatomy among medical students, facilitating the understanding and memorization of anatomical information. While cadaver dissection remains an irreplaceable part of medical education, the addition of YouTube as a learning resource can enhance the educational experience. Future research should focus on the in-depth exploration of content satisfaction and the potential role of YouTube in the broader anatomy curriculum.
RESUMO
Introduction Accurate diagnosis of deep-seated abdominopelvic masses is crucial to distinguish malignant from non-malignant lesions for proper treatment and prognosis. Ultrasonography-guided fine needle aspiration cytology (USG-FNAC) is a cost-effective and straightforward procedure that offers rapid diagnosis, facilitating early initiation of treatment. This study aimed to determine the diagnostic accuracy of USG-FNAC in comparison to the biopsy diagnosis of various abdominopelvic masses in a resource-limited setting. Materials and methods This prospective study enrolled 208 patients with clinically and ultrasonographically confirmed abdominopelvic masses over two years. Of these, 64 cases were excluded from the study because of the non-availability of biopsy specimens. The remaining 144 cases comprised 88 males and 56 females, with a male-to-female ratio of 1.57:1. Patients' ages ranged from 1.5 to 65 years, with most male patients aged 51 to 60 years and female patients aged 41 to 50 years. USG-FNAC was performed on these patients using a 22G spinal needle and a 10cc disposable syringe, and no complications were reported during the procedure. The cytological findings were compared to histopathological results when available. Dry smears were stained with May-Grunwald-Giemsa stain, while fixed smears were stained with Papanicolaou stain for cytological investigation. Results A total of 144 cases had both cytological and histological specimens available for comparison. The overall diagnostic accuracy of USG-FNAC was 90.97%, with 91.8% sensitivity for malignant lesions, 83.33% for benign lesions, and 85.7% for inflammatory lesions. Conclusions USG-FNAC provides high diagnostic accuracy for abdominopelvic masses, making it a valuable diagnostic tool in resource-limited settings. The technique allows for rapid diagnosis, triaging specimens for ancillary immunohistochemical and molecular studies, and in many cases, obviates the need for more expensive and time-consuming procedures like laparotomy and open biopsy.
