Mutations in PDS (SLC26A4) cause both Pendred syndrome and DFNB4, two autosomal recessive disorders that share hearing loss as a common feature. The hearing loss is associated with temporal bone abnormalities, ranging from isolated enlargement of the vestibular aqueduct (dilated vestibular aqueduct, DVA) to Mondini dysplasia, a complex malformation in which(More)
Recombinant adenoviruses are currently being used as vectors for gene delivery to a wide variety of cells and tissues. Although generally efficacious for gene transfer in vitro, improvement in the efficiency of vector delivery in vivo may aid several gene therapy applications. One major obstacle is the lack of high-affinity viral receptors on the surface of(More)
BACKGROUND Cutaneous squamous cell carcinoma (CSCC) is the second most common nonmelanoma skin cancer. Most of the approximately 250,000 cases occurring annually in the United States are small, nonaggressive, and cured by excision alone. However, a subset of these tumors which are defined by poorly differentiated histology, large tumor size, invasion of(More)
Grisel's syndrome is non-traumatic atlantoaxial subluxation (AAS) secondary to an inflammatory process in the upper neck. It is a rare condition that occurs almost exclusively in children and has been associated with upper cervical infections and otolaryngologic procedures. A case of AAS secondary to an upper cervical infection is presented. Potential(More)
Although there is a great amount in the literature to describe the anatomy of the parotid gland as a whole, little attention is given to the parotid duct. The purpose of this study is to examine the surgical anatomy of the parotid duct with special emphasis placed on the major tributaries forming the parotid duct and the relationship of the facial nerve to(More)
Epidermal growth factor receptor (EGFR) has been characterized as a critical factor in the development and progression of multiple solid tumors, including head and neck squamous cell carcinoma (HNSCC). However, monotherapy with EGFR-specific agents has not been as dramatic as preclinical studies have suggested. Since complex regulation of the EGFR signaling(More)
PURPOSE Anaplastic thyroid carcinoma (ATC) is one of the most lethal human cancers with a median survival of 6 months. The inhibition of epidermal growth factor receptor (EGFR) alone, or with VEGF receptor 2 (VEGFR2), represents an attractive approach for treatment of ATC. Several reports have examined agents that target these receptors. However, with the(More)
BACKGROUND The purpose of this study was to identify mechanisms of innate resistance to an epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor, erlotinib, in a panel of head and neck squamous cell carcinoma (HNSCC) cell lines. Specifically, we analyzed the role of HRAS mutations in erlotinib resistance. METHODS Erlotinib sensitivity was(More)
OBJECTIVE To evaluate the therapeutic effect of treatment with a combination of the monoclonal antibodies to the vascular endothelial growth factor receptor (DC101) and the epidermal growth factor receptor (cetuximab) in an orthotopic nude mouse model of metastatic squamous cell carcinoma of the oral tongue (SCCOT). DESIGN In vivo study. SETTING A(More)
A major hurdle to the successful clinical use of some viral vectors relates to the innate, adaptive, and memory immune responses that limit the efficiency and duration of transgene expression. Some of these drawbacks may be circumvented by using vectors derived from nonhuman viruses such as canine adenovirus type 2 (CAV-2). Here, we evaluated the potential(More)
