Division of Gastroenterology and Hepatology Faculty Papers
BACKGROUND: Epigallocatechin-3-gallate (EGCG) has antiangiogenic, antioxidant, and antifibrotic properties that may have therapeutic potential for the treatment of cirrhosis induced by hepatitis C virus (HCV). However, cirrhosis might affect EGCG disposition and augment its reported dose-dependent hepatotoxic potential.
OBJECTIVE: The safety, tolerability, and disposition of a single oral dose of EGCG in cirrhotic patients with HCV were examined in an exploratory fashion.
METHODS: Eleven patients with hepatitis C and detectable viremia were enrolled. Four had Child-Pugh (CP) class A cirrhosis, 4 had Child-Pugh class B cirrhosis, and 3 were noncirrhotic. After a single oral dose of green tea extract 400 …

Introduction:
Rats are frequently utilized for both research and training related to reconstructive head and neck surgery. The femoral neurovascular complex represents a useful mode for microvascular anastomosis, both for the purposes of testing adjuncts designed to improve anastomotic patency rates, as well as for residents and students to gain experience in microvascular surgery outside the operating room. Additionally, the rat proves useful in investigations examining the survivability of both random and axial pattern skin flaps.

Conclusions:
Aberrant CD56 expression on granulocytes is seen in all aubtypes MPN and high grade MDS. CD56 expression in MPN correlated with bone marrow morphology, BCR/ABL transcript, and bone marrow engraftment study following treatment. Identification of abnormal CD56+ granulocytes and monocytes is helpful in both the initial diagnosis and long-term follow up of patients with MPN and MDS.

Department of Pathology, Anatomy, and Cell Biology Faculty Papers
Conclusions:
Loss of RB tumor suppressor staining in pre-treatment breast cancer biopsies can be used prior to initiation of neoadjuvant chemotherapy to predict good tumor response. This association between RB loss and good neoadjuvant response holds regardless of ER status and across various chemotherapy regimens. Assessment of RB status in the pre-treatment biopsy could be useful clinical tool to define patients who are most likely to benefit from neoadjuvant chemotherapy.

Background and Objectives
High risk HPV is associated with oropharyngeal SCC (OSCC) and is responsible for the increasing incidence of this cancer type among younger patients.
Patients with HPV positive oropharyngeal SCC have a better prognosis when compared with HPV negative, tobacco induced SCC.
HPV E6 inactivates p53 leading to low expression of p53; tobacco induced oropharyngeal SCC is characterized by p53 overexpression, resistance to treatment and poor prognosis. However, in many cases of HPV OSCC, there is a history of current or remote smoking, making this disease a multifactorial process. We expect that smoking will influence the level of …

Background:
• Neuroimaging is a diagnostic tool that may be used to rule out a serious condition when a patient presents with head pain. It is not typically warranted for patients who have a normal neurologic exam, and may be over utilized despite established practice parameters set by the American Academy of Neurology.
•A decision to use neuroimaging should consider the type of headache and presence of any clinical features that suggest a serious condition.
Over-utilization of neuroimaging has cost and safety implications.
The United States Headache Consortium, a panel of experts on migraine, set the guidelines for diagnosis and …

Background
Safety concerns exist when using triptansto treat patients with cardiac contraindications.
–Triptans cause vasoconstriction, a safety concern for migraineurswith cardiovascular (CV) disease or other cardiac risk factors.
–All triptans contain contraindications in their package inserts to avoid use in patients with cardiac conditions.
•Previous research indicates that clinicians are less likely to prescribe triptansin patients with CV disease or CV risk factors.
Limited research has examined the proportion of migraine patients with cardiovascular disease or those individuals who were concurrently treated with triptans.

Does International Normalized Ratio Level Predict Pulmonary Embolism?, Patricia Hansen, Benjamin Zmistowski, Camilo Restrepo, Javad Parvizi, Richard H Rothman
Rothman Institute Faculty Papers
BACKGROUND: Preventing pulmonary embolism is a priority after major musculoskeletal surgery. The literature contains discrepant data regarding the influence of anticoagulation on the incidence of pulmonary embolism after joint arthroplasty. The American College of Chest Physicians guidelines recommend administration of oral anticoagulants (warfarin), aiming for an international normalized ratio (INR) level between 2 and 3. However, recent studies show aggressive anticoagulation (INR > 2) can lead to hematoma formation and increased risk of subsequent infection.
QUESTIONS/PURPOSES: We asked whether an INR greater than 2 protects against pulmonary embolism.
PATIENTS AND METHODS: We identified 9112 patients with 10,122 admissions for joint arthroplasty …

Left Atrial Volume: Comparison Of 2d And 3d Transthoracic Echocardiography With Ecg-Gated Ct Angiography., Anish R Koka, Stuart D Gould, Alyson N Owen, Ethan J. Halpern
Department of Radiology Faculty Papers
RATIONALE AND OBJECTIVES: Left atrial volume (LAV) measurement by conventional two-dimensional (2D) transthoracic echocardiography (TTE) may be limited by the geometric model, by suboptimal definition of left atrial endocardium, or by chamber foreshortening. Three-dimensional (3D) TTE is posited to eliminate chamber foreshortening, and LAV measurement by 3D TTE should be more reflective of true LAV. The aim of this study was to compare conventional 2D TTE and newer 3D TTE for measurements of LAV to multidetector computed tomographic (MDCT) measurements using automated chamber reconstruction (ACR).
MATERIALS AND METHODS: Twenty-two subjects consented to undergo 2D TTE and 3D TTE immediately prior …

Department of Surgery Faculty Papers
INTRODUCTION: The incidence of melanoma is dramatically increasing worldwide. We hypothesized that the ratio of metastatic to examined lymph node ratio (LNR) would be the most important prognostic factor for stage III patients.
METHODS: We retrospectively reviewed our institutional database of melanoma patients and identified 168 patients who underwent lymph node dissection (LND) for stage III disease between 1993 and 2007. Patients were divided into three groups based on LNR (≤10%, n = 93; 10-≤25%, n = 45; and >25%, n = 30). Univariate and multivariate analysis was performed using Cox proportional hazards model.
RESULTS: The median survival time of …

Department of Neurology Faculty Papers
PURPOSE: We previously demonstrated that converting patients from the enzyme-inducers phenytoin or carbamazepine to the non-inducers levetiracetam or lamotrigine reduces serum lipids and C-reactive protein (CRP). We sought to determine if the same changes would occur when patients were switched to topiramate, which has shown some evidence of enzyme induction at high doses. We also examined the effects of drug switch on low-density lipoprotein (LDL) particle concentration.
METHODS: We converted 13 patients from phenytoin or carbamazepine monotherapy to topiramate monotherapy (most at doses of 100-150 mg/day). Fasting lipids, including LDL particle concentration, and CRP were obtained before and ≥6 weeks …
Trends In The Utilization Of Outpatient Advanced Imaging After The Deficit Reduction Act., David C Levin, Vijay M Rao, Laurence Parker
Trends In The Utilization Of Outpatient Advanced Imaging After The Deficit Reduction Act., David C Levin, Vijay M Rao, Laurence Parker
Department of Radiology Faculty Papers
PURPOSE: After the Deficit Reduction Act (DRA) took effect in 2007, there was concern that private office-based imaging facilities would close, that advanced imaging would shift to less convenient hospital-based facilities, and that access to advanced imaging might be restricted. The aim of this study was to see if these developments occurred during the years after the DRA.
METHODS: Using Medicare data, outpatient CT, MRI, and nuclear medicine trends before and after the DRA were studied. Procedure volumes performed in private offices and hospital outpatient departments (HOPDs) were tabulated separately. Volumes were tracked from 2000 to 2006 (before the DRA) …

PURPOSE: To investigate the expression of the myocilin gene (MYOC) in the blood of primary open angle glaucoma (POAG) patients to determine if altered systemic expression is playing a role.
METHODS: Patients (n=47) were eligible for inclusion if they met standard clinical criteria for POAG. Control subjects (n=27) were recruited who were free from glaucoma by examination. RNA was extracted from leukocytes of patients and controls and converted to cDNA by reverse transcriptase enzyme, and quantitative PCR was used to assess expression levels of MYOC and the house keeping gene β-globulin (HBB). The ratio of MYOC expression to HBB expression …

Manifestations Of Rheumatoid Arthritis: Epidural Pannus And Atlantoaxial Subluxation Resulting In Basilar Invagination., Adam L Schreiber, Do, Ma
Department of Rehabilitation Medicine Faculty Papers
Presented in part at the AAPMR 71st Annual Assembly Meeting, Seattle, WA, November 4-7, 2010.
Atlantoaxial instability results from cartilaginous destruction, periarticular erosions, and ligament and tendon attenuation. Instability affects 19%-70% of patients, and basilar invagination from vertical odontoid subluxation through the foramen magnum occurs in 38% of patients. This phenomenon occurs twice as often in women than men, whose age at diagnosis typically ranges from 30-50 years. Along with bony compression, the pannus further decreases the space available for the cord by 3mmor more in approximately 66% of patients (Figures 1-7). The earliest and most common symptom of cervical …
