BACKGROUND Thick melanomas (TM) ≥4 mm have a high risk for nodal and distant metastases. Optimal surgical management, prognostic significance of sentinel node biopsy (SLNB), and benefits of interferon (IFN) for these patients are unclear. As a continuum of increasing tumor thickness is placed into a single TM group, differences in biologic and clinical(More)
It has been hypothesized that lax vowels may be relatively unaffected by dysarthria, owing to the reduced vocal tract shapes required for these phonetic events (G. S. Turner, K. Tjaden, & G. Weismer, 1995). It also has been suggested that lax vowels may be especially susceptible to speech mode effects (M. A. Picheny, N. I. Durlach, & L. D. Braida, 1986).(More)
Recent growth of daVinci Robotic Surgical System as a minimally invasive surgery tool has led to a call for better training of future surgeons. In this paper, a new virtual reality simulator, called RoSS is presented. Initial results from two studies - face and content validity, are very encouraging. 90% of the cohort of expert robotic surgeons felt that(More)
BACKGROUND AND OBJECTIVES Obesity is a major comorbidity in the Western world and influences outcomes of patient care. A minimally invasive approach towards radical cystectomy has been increasing in popularity. We sought to determine the influence of body mass index (BMI) on robot-assisted radical cystectomy. METHODS Fifty-one consecutive patients(More)
BACKGROUND A standardized scoring system does not exist in virtual reality-based assessment metrics to describe safe and crucial surgical skills in robot-assisted surgery. This study aims to develop an assessment score along with its construct validation. MATERIALS AND METHODS All subjects performed key tasks on previously validated Fundamental Skills of(More)
BACKGROUND The purpose of this study was for us to report results regarding the safety of 3-(1'-hexyloxyethyl) pyropheophorbide-a (HPPH) mediated photodynamic therapy (PDT) in early laryngeal disease, and offer preliminary information on treatment responses. METHODS A single-institution, phase Ib, open label, noncomparative study of HPPH-PDT in patients(More)
PURPOSE This study obtained judgments of sentence intelligibility using orthographic transcription for comparison with previously reported intelligibility judgments obtained using a visual analog scale (VAS) for individuals with Parkinson's disease and multiple sclerosis and healthy controls (K. Tjaden, J. E. Sussman, & G. E. Wilding, 2014). METHOD(More)
