BACKGROUND CONTEXT C5 nerve root palsy (C5P) is a relatively rare complication after anterior and posterior cervical decompression surgery that leads to a variety of debilitating symptoms. The precise etiology remains obscure, and a clear understanding of preoperative risk factors for C5P development does not exist. PURPOSE To determine whether(More)
STUDY DESIGN A consecutive retrospective cohort study from 2008 to 2013 at a single tertiary-care institution was conducted. OBJECTIVE The aim of the study was to characterize recovery from pain and neurologic deficit after surgery for vertebral osteomyelitis (VO), and identify incidence of postoperative adverse events. SUMMARY OF BACKGROUND DATA A(More)
The reaction of the methylidyne radical (CH) with acetone ((CH(3))(2)C[double bond, length as m-dash]O) is studied at room temperature and at a pressure of 4 Torr (533.3 Pa) using a multiplexed photoionization mass spectrometer coupled to the tunable vacuum ultraviolet synchrotron radiation of the Advanced Light Source at Lawrence Berkeley National(More)
BACKGROUND CONTEXT Some, smaller studies have investigated the effect of preoperative depression on postoperative improvement in quality of life (QOL). However, they have not used the Patient Health Questionnaire 9 (PHQ-9) in self-reported depression. PURPOSE To assess the effect of preoperative depression as measured by the PHQ-9 on postoperative(More)
BACKGROUND Few studies have examined the general correlation between socioeconomic status and imaging. This study is the first to analyze this relationship in the spine patient population. OBJECTIVE To assess the effect of socioeconomic status on the frequency with which imaging studies of the lumbar spine are ordered and completed. METHODS Patients(More)
Circulating tumor cells have emerged as prognostic biomarkers in the treatment of metastatic cancers of epithelial origins viz., breast, colorectal and prostate. These tumors express Epithelial Cell Adhesion Molecule (EpCAM) on their cell surface which is used as an antigen for immunoaffinity capture. However, EpCAM capture technologies are of limited(More)
Comparison of tumors from The Cancer Genome Atlas (TCGA) reveals that head and neck squamous cell carcinomas (HNSCC) harbor the most frequent genomic amplifications of Fas-associated death domain (FADD), with or without Baculovirus inhibitor of apoptosis repeat containing BIRC2 (cIAP1), affecting about 30% of patients in association with worse prognosis.(More)
The Cancer Genome Atlas (TCGA) has unveiled genomic deregulation of various components of the extrinsic and intrinsic apoptotic pathways in different types of cancers. Such alterations are particularly common in head and neck squamous cell carcinomas (HNSCC), which frequently display amplification and overexpression of the Fas-associated via death domain(More)
STUDY DESIGN A retrospective 1-year cost-utility analysis. OBJECTIVE To determine the cost-effectiveness of using recombinant human bone morphogenic protein (rhBMP-2) in addition to autograft for 1- and 2-level lumbar fusions. SUMMARY OF BACKGROUND DATA rhBMP-2 has been studied extensively to identify its benefits, risks, patient outcomes, and costs(More)
results: Total supraplatysmal fat volume was significantly greater than subplatysmal volume within both the “young” and “elderly”; however, “young” had significantly more total supraplatysmal fat than “elderly” (p<0.0001). There was no significant difference in fat volume between each third of the neck in the supraplatysmal compartment in “young”. The(More)
