Volume-outcome associations exist for head and neck oncologic procedures, although this has not been fully investigated for salivary gland malignancies. Future quality of care studies in head and neck oncology should focus on processes of care, which may explain this relationship.
This systematic review of the literature and meta-analysis of the pattern of spread indicates significant rates of lymph node metastasis to all lateral neck levels in patients with PTC with regional involvement. This evidence leads us to recommend a comprehensive selective neck dissection of levels IIa, IIb, III, IV, and Vb in patients with lateral neck disease from PTC. The evidence for level Va is lacking, as most studies did not distinguish between levels Va and Vb, and the border between the two levels was inconsistent. Future studies will need to address these sublevels separately.
Based on radiologic findings, risk factors, and FNA results, many incidental thyroid nodules can be observed. Incidental thyroid nodules should be evaluated in the same fashion as a palpable thyroid nodule.
Human papillomavirus (HPV), the most common sexually transmitted infection worldwide, is responsible for a variety of cancers. HPV vaccines can help prevent this infection and its potentially devastating carcinogenic outcomes. Although the incidence of HPV-related oropharyngeal cancers among males is increasing, few studies have been published on HPV knowledge and vaccine acceptability among males. In this cross-sectional study, we assessed knowledge about HPV and the vaccine, as well as its acceptability, among third- and fourth-year male medical students in Jeddah, Saudi Arabia. Respondents were enrolled in any of the medical colleges in Jeddah from February to December 2018. A validated survey was used to collect information on HPV infection and vaccine knowledge and to ask questions assessing vaccine acceptability. HPV knowledge scores were created, and vaccine acceptability predictors were assessed with logistic regression. We collected data from 517 participants. Approximately 74% of the students had heard of HPV, with a mean knowledge score of 5.9 ± 4.6 out of 16; only 42% had heard of the HPV vaccine, with a mean knowledge score of 0.9 ± 1.6 out of 7. Among the respondents, 48.9% were interested in receiving the HPV vaccine. Although HPV infection and vaccine knowledge did not correlate with vaccine acceptability, those who had previously received the hepatitis B vaccine were more interested in receiving the HPV vaccine. In conclusion, male medical students had low HPV knowledge. Improving their HPV knowledge is important, as they are future health-care providers. The promotion of HPV vaccines in this potentially influential group is crucial for achieving effective disease prevention.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
