PURPOSE Patients with recurrent head and neck squamous cell carcinoma (HNSCC) present a diagnostic and therapeutic challenge. We evaluated the diagnostic accuracy and prognostic value of [(18)F]fluorodeoxyglucose positron emission tomography (PET) in this patient population. PATIENTS AND METHODS We performed a retrospective review of 143 patients with(More)
A new interventional radiologic procedure was developed for treatment of epiphora. A small-bore, soft-tipped guide wire was introduced through the superior canaliculus and guided under fluoroscopic control through the nasolacrimal drainage system for retrieval through the nasal aperture. A small-bore angioplasty catheter was then introduced in a retrograde(More)
Cyclooxygenase-2 (COX-2), an enzyme that catalyzes the synthesis of prostaglandins, is overexpressed in a variety of premalignant and malignant conditions, including oral leukoplakia and squamous cell carcinoma of the head and neck. Increased levels of COX-2 may contribute to carcinogenesis by modulating xenobiotic metabolism, apoptosis, immune(More)
Real-time sonography of the eye is a technique that is rapidly performed and readily available in most sonography departments. It is less expensive than CT and MR imaging and, if necessary, may be performed at the patient's bedside. This essay demonstrates a few of the large number of clinical entities that may be successfully examined with this technique.
OBJECTIVE The objective is to present an uncommon case of squamous cell carcinoma (SCC) arising from extensive recurrent respiratory papillomatosis (RRP) involving the upper and lower airway and temporal bone. STUDY DESIGN This is a case report and a review of the literature. METHODS We describe a case of a 24-year-old woman with a history of human(More)
OBJECTIVES Distinction of intestinal-type sinonasal adenocarcinoma (ITAC) from adenocarcinoma of intestinal origin metastatic to the sinonasal cavity may be extremely difficult on histologic grounds alone. We studied the role of cytokeratin (CK) and mucin (MUC) expression in differentiating ITAC, metastatic adenocarcinoma of intestinal origin, and(More)
OBJECTIVES To assess the incidence of unintentional parathyroid removal during routine thyroidectomy and to identify factors that might predict patients at high risk. STUDY DESIGN Retrospective review of case records. Data analyzed for incidental finding of parathyroid gland(s) in the thyroidectomy specimen and postoperative temporary or permanent(More)
OBJECTIVES/HYPOTHESIS The pathophysiology underlying human olfactory disorders is poorly understood because biopsying the olfactory epithelium (OE) can be unrepresentative and extensive immunohistochemical analysis is lacking. Autopsy tissue enriches our grasp of normal and abnormal olfactory immunohistology and guides the sampling of the OE by biopsy.(More)
Real-time sonography was evaluated retrospectively in 71 consecutive patients with ocular trauma. A total of 51 vitreous hemorrhages, 20 hemorrhages in the anterior chamber, 22 retinal detachments, seven choroidal detachments, five foreign bodies, and 12 dislocated lenses were identified sonographically. In 10 instances (three choroidal detachments, six(More)
Corneal topographic analysis was performed on 97 consecutive eyes with at least one month follow-up after excimer laser photorefractive keratectomy for myopia. Centration of the ablated zone was documented in all eyes at the one month postoperative examination with the Topographic Modeling System (Computed Anatomy Inc., NY). Thirty-seven percent of eyes(More)
