RESUMO

BACKGROUND: Videos on YouTube can be posted without regulation or content oversight. Unfortunately, many patients use YouTube as a resource on aesthetic surgery, leading to misinformation. Currently, there are no objective assessments of the quality of information on YouTube about aesthetic surgery. METHODS: YouTube was queried for videos about the 12 most common aesthetic surgical procedures, identified from the 2015 American Society of Plastic Surgeons procedural statistics between May and June of 2016. The top 25 results for each search term were scored using the modified Ensuring Quality Information for Patients criteria based on video structure, content, and author identification. Average Ensuring Quality Information for Patients score, view count, and video duration were compared between authorship groups. RESULTS: A total of 523 videos were graded after excluding duplicates. The mean modified Ensuring Quality Information for Patients score for all videos was 13.1 (SE, 0.18) of a possible 27. The videos under the search "nose reshaping" had the lowest mean score of 10.24 (SE, 0.74), whereas "breast augmentation" had the highest score of 15.96 (SE, 0.65). Physician authorship accounted for 59 percent of included videos and had a higher mean Ensuring Quality Information for Patients score than those by patients. Only three of the 21 search terms had a mean modified Ensuring Quality Information for Patients score meeting criteria for high-quality videos. CONCLUSIONS: The information contained in aesthetic surgery videos on YouTube is low quality. Patients should be aware that the information has the potential to be inaccurate. Plastic surgeons should be encouraged to develop high-quality videos to educate patients.

RESUMO

PURPOSE: In pediatric cancer survivors treated with whole-brain irradiation (WBI), long-term cognitive deficits and morbidity develop that are poorly understood and for which there is no treatment. We describe similar cognitive defects in juvenile WBI rats and correlate them with alterations in diffusion tensor imaging and magnetic resonance spectroscopy (MRS) during brain development. METHODS AND MATERIALS: Juvenile Fischer rats received clinically relevant fractionated doses of WBI or a high-dose exposure. Diffusion tensor imaging and MRS were performed at the time of WBI and during the subacute (3-month) and late (6-month) phases, before behavioral testing. RESULTS: Fractional anisotropy in the splenium of the corpus callosum increased steadily over the study period, reflecting brain development. WBI did not alter the subacute response, but thereafter there was no further increase in fractional anisotropy, especially in the high-dose group. Similarly, the ratios of various MRS metabolites to creatine increased over the study period, and in general, the most significant changes after WBI were during the late phase and with the higher dose. The most dramatic changes observed were in glutamine-creatine ratios that failed to increase normally between 3 and 6 months after either radiation dose. WBI did not affect the ambulatory response to novel open field testing in the subacute phase, but locomotor habituation was impaired and anxiety-like behaviors increased. As for cognitive measures, the most dramatic impairments were in novel object recognition late after either dose of WBI. CONCLUSIONS: The developing brains of juvenile rats given clinically relevant fractionated doses of WBI show few abnormalities in the subacute phase but marked late cognitive alterations that may be linked with perturbed MRS signals measured in the corpus callosum. This pathomimetic phenotype of clinically relevant cranial irradiation effects may be useful for modeling, mechanistic evaluations, and testing of mitigation approaches.
