OBJECTIVE Recent studies have identified an abundant source of multipotent progenitor cells in subcutaneous human adipose tissue, termed human adipose-derived adult stem cells (ADAS cells). In response to specific media formulations, including transforming growth factor beta1 (TGFbeta1), these cells exhibit significant ability to differentiate into a(More)
Actinomycosis is a rare anaerobic bacterial infection typically caused by Actinomyces israelii. Although part of normal flora in the oral cavity, and respiratory and digestive tracts, A israelii can give rise to pathologic infections most commonly reported in the oral cavity from odontogenic causes. We present a rare case of invasive actinomycosis(More)
AIMS Survey the clinical symptoms, radiological features, management, and long-term outcomes of sinonasal and anterior skull base schwannomas. PATIENTS AND METHODS Retrospective review of patients with sinonasal schwannomas treated from June 2001 through January 2010 at two academic institutions. RESULTS There were 4 women and 3 men in this study. The(More)
BACKGROUND recently, there has been a debate regarding total thyroidectomy vs hemithyroidectomy for papillary thyroid microcarcinoma (PTMC). OBJECTIVE to determine whether there were significant differences in the treatment of PTMC depending on a physician's experience, age, training, and location. METHODS a 10-question survey was distributed to(More)
Head and neck squamous cell carcinoma (HNSCC) is the sixth most common cancer, with 600,000 new cases every year worldwide. Although chemotherapeutics exist, five-year survival is only 50%. New strategies to overcome drug resistance are required to improve HNSCC treatment. Curcumin-difluorinated (CDF), a synthetic analog of curcumin, was packaged in(More)
OBJECTIVES Juvenile nasopharyngeal angiofibroma (JNA) is a rare, benign tumor of the nasopharynx, exclusively affecting males in their teens and twenties. Historically, it has been thought that JNAs primarily receive their blood supply from the ipsilateral external carotid system. We demonstrate in our case series and literature review that bilateral(More)
Adipose-derived adult stem (ADAS) cells represent an abundant population of multipotent mesodermal cells residing in various adipose tissue depots. ADAS cell preparations appear heterogeneous, yet at a clonal level, greater than 50% of these cells exhibit multilineage differentiation potential. To date, there have been few attempts to define prospectively a(More)
OBJECTIVE Craniopharyngiomas and similar midline suprasellar tumors have traditionally been resected via transcranial approaches. More recently, expanded endoscopic endonasal transsphenoidal approaches have gained interest. Surgeons have advocated for both approaches, and at present there is no consensus whether one approach is superior to the other. The(More)
BACKGROUND & AIMS Patients undergoing gastrointestinal operations are at risk of malnutrition which may increase the chance of adverse surgical outcomes. This prospective study aimed at correlating nutritional status of patients having gastrointestinal operations with their short-term surgical outcomes captured by a territory-wide Surgical Outcomes(More)
OBJECTIVES/HYPOTHESIS To determine the long-term results of frontal sinus drillout (also known as modified Lothrop procedure) for the treatment of advanced frontal sinus disease. STUDY DESIGN Retrospective review. METHODS The records of patients who underwent frontal sinus drillout by a single surgeon at an academic medical center from June 1995 through(More)
