PURPOSE To assess diagnostic accuracy of fluorine 18 ((18)F) fluorodeoxyglucose (FDG) combined positron emission tomography (PET) and computed tomography (CT) in the detection of occult primary tumors and determination of optimal care in patients with cervical metastasis of an unknown primary tumor (CUP) compared with contrast material-enhanced CT alone or(More)
Extranodal extension (ENE) is a poor prognostic indicator for patients with head and neck squamous cell carcinoma (HNSCC), but pretreatment detection assists with proper treatment planning. This study evaluated whether the ENE of HNSCC is accurately detected by computed tomography (CT) versus fluorine 18-fluorodeoxyglucose (18F-FDG) positron emission(More)
OBJECTIVES We evaluated vestibular function test results in vestibular migraine (VM) patients, including caloric, vestibular evoked myogenic potential (VEMP), and dynamic posturography measurements and assessed their relationship with treatment responses. STUDY DESIGN Retrospective case series review. SETTING Tertiary referral center. METHODS We(More)
Intracellular antioxidant enzymes are commonly upregulated in various cancer types and are associated with treatment outcomes. Because the relationship has rarely been examined in oral squamous cell carcinoma (OSCC), we aimed to evaluate the association between the levels of glutathione peroxidase (GPX)1, GPX4, and thioredoxin reductase (TrxR)1 expression(More)
OBJECTIVE Transcutaneous devices have a disadvantage, the dampening effect by soft tissue between the bone and devices. We investigated hearing outcomes with percutaneous and transcutaneous devices using test-bands in an induced unilateral conductive hearing loss. DESIGN Comparison of hearing outcomes of two devices in the same individuals. STUDY SAMPLE(More)
Herein we describe two cases of nasal glomus tumor. Histological findings were typical, save for one which was quite large (3.1 cm in its greatest dimension) with an invasive growth pattern and increased ki-67 labeling index (up to 10%). These features raised a red flag of similarity to a recently described “invasive glomus tumor of nasal cavity”,(More)
