Esophageal perforations due to foreign bodies are rare but carry potentially devastating complications. Delays in diagnosis are common, and no standard diagnostic algorithm exists. Lateral neck X-rays are an easy but insensitive screening test. Laryngoscopy is an excellent screening test but not always diagnostic. CT is a more sensitive diagnostic method, which can also help guide management based on the detection of complications. Although seldom described, if an object is not visualized at the time of endoscopic or surgical intervention, follow-up CT may be useful in determining the persistence of effects of the perforation or the foreign body.
HR-HPV detection and genotyping can be performed on lymph node FNAs with metastatic squamous cell carcinoma using the Roche cobas 4800 system. The presence of HR-HPV and/or HPV 16 is a reliable indicator of the metastatic squamous cell carcinoma originating from the oropharynx.
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.
