Bowel entrapment within a pelvic fracture is a rarely reported but potentially fatal complication. Diagnosis is often delayed due to difficulty in differentiating entrapment from the more common adynamic ileus. Computed tomography of the abdomen and pelvis with enteric contrast can be useful in making the diagnosis. We report an unusual case of bowel(More)
Cervical cancer originates with human papillomavirus (HPV) infection and progresses via histologically-defined premalignant stages. Here we compare normal cervical epithelium and patient-matched high grade squamous intraepithelial lesions (HSIL) with cervical carcinoma tissue from the same patient population (n=10 per group). Specimens were analyzed by(More)
OBJECTIVE HSPB1 functions to prevent stress-induced cellular damage and has is elevated in multiple cancer types. The significance of HSPB1 in HNSCC remains controversial. We sought to perform a meta-analysis of HSPB1 expression to clarify previous findings. STUDY DESIGN Meta-analysis of all published studies of HSPB1 in HNSCC patients using IHC(More)
OBJECTIVE The purpose of this study was to determine if oropharyngeal squamous cell carcinoma (OSCC) classified into three groups based on human papillomavirus (HPV) 16 DNA presence and p16 expression display different protein expression patterns. STUDY DESIGN Cross-sectional study. SETTING A laboratory-based study of patients with OSCC treated at a(More)
OBJECTIVES/HYPOTHESIS Mortality for black males with head and neck squamous cell carcinoma (HNSCC) is twice that of white males or females. Human papillomavirus (HPV)-active HNSCC, defined by the concurrent presence of high-risk type HPV DNA and host cell p16(INK4a) expression, is associated with decreased mortality. We hypothesized that prevalence of this(More)
OBJECTIVE Identify proteins that are differentially expressed between head and neck squamous cell cancer (HNSCC) and patient-matched normal adjacent tissue, and validate findings in a separate patient cohort. STUDY DESIGN Cross-sectional study of surgical specimens. SETTING Tertiary care academic medical center. SUBJECTS AND METHODS Laser capture(More)
OBJECTIVES (1) Determine factors influencing survival in patients diagnosed with spindle cell carcinoma (SpCC), a rare variant of head and neck squamous cell carcinoma (SCC). (2) Compare survival of patients with SpCC to those with conventional SCC. STUDY DESIGN Retrospective cohort study. SETTING Surveillance, Epidemiology, and End Results 18 database(More)
Infection with high-risk type human papilloma viruses (HPVs) is associated with cervical carcinomas and with a subset of head and neck squamous cell carcinomas. Viral E6 and E7 oncogenes cooperate to achieve cell immortalization by a mechanism that is not yet fully understood. Here, human keratinocytes were immortalized by long-term expression of HPV type(More)
Bacteria should be excellent indicators of the early signs of degradation caused by human intervention because they have the highest surface area to volume ratio of all organisms. We determined the utility of a simple procedure that measures aerobic bacterial metabolic diversity (BIOLOG EcoPlates) as a reliable tool for assessing the effects of cattle(More)
Eukaryotic cells begin to assemble discrete, nucleoplasmic repair foci within seconds after the onset of exposure to ionizing radiation. Real-time imaging of this assembly has the potential to further our understanding of the effects of medical and environmental radiation exposure. Here, we describe a microirradiation system for targeted delivery of(More)
