Department of Urology Faculty Papers

BACKGROUND AND OBJECTIVES: Laparoscopic renal surgery has become a widely applied technique in recent years. The development of postoperative rhabdomyolysis is a known but rare complication of laparoscopic renal surgery. Herein, 4 cases of rhabdomyolysis and a review of the literature are presented with respect to pathogenesis, treatment, and prevention of this dire complication. METHODS: A retrospective review of over 600 laparoscopic renal operations over the past 8 years was performed. All cases of postoperative rhabdomyolysis were identified. A Medline search was performed to find articles related to the development of postoperative rhabdomyolysis. Cases of rhabdomyolysis developing after laparoscopic renal …

T Cells Expressing Allograft Inflammatory Factor 1 Display Increased Chemotaxis And Induce A Profibrotic Phenotype In Normal Fibroblasts In Vitro, Francesco Del Galdo M.D., Ph.D., Sergio A. Jimenez M.D.

Department of Dermatology and Cutaneous Biology Faculty Papers

Objective. Allograft inflammatory factor 1 (AIF-1) was first identified in rat cardiac allografts undergoing chronic rejection. The vasculopathy of chronic allograft rejection is strikingly similar to that seen in patients with systemic sclerosis (SSc). We previously demonstrated AIF-1 expression in inflammatory cells infiltrating skin and lungs from SSc patients, but its role in SSc pathogenesis is unknown. The present study was undertaken to investigate the effects of AIF-1 on T cell migration and production of cytokines capable of modulating normal dermal fibroblast functions.

Methods. Stably transfected Jurkat T cells expressing 2 AIF-1 splicing variants were prepared, and their migration toward …

Microvascular Endothelial Cells Express A Phosphatidylserine Receptor: A Functionally Active Receptor For Phosphatidylserine-Positive Erythrocytes, Yamaja Setty, Suhita Gayen Betal

Department of Pediatrics Faculty Papers

Phosphatidylserine (PS)-positive erythrocytes adhere to endothelium and subendothelial matrix components. While thrombospondin mediates these inter-actions, it is unknown whether PS-associated erythrocyte-endothelial adhesion occurs in the absence of plasma ligands. Using ionophore-treated PS-expressing control HbAA erythrocytes, we demonstrate that PS-positive erythrocytes adhered to human lung microendothelial cells in the absence of plasma ligands, that this adhesion was enhanced following endothelial activation with IL-1alpha, TNF-alpha, LPS, hypoxia, and heme, and that this adhesive interaction was selective to erythrocyte PS. We next explored whether microendothelial cells express an adhesion receptor that recognizes cell surface-expressed PS (PSR) similar to that expressed on activated macrophages. …

Regional Variability In Use Of A Novel Assessment Of Thoracolumbar Spine Fractures: United States Versus International Surgeons., John Ratliff, Neel Anand, Alexander R Vaccaro, Moe R Lim, Joon Y Lee, Paul Arnold, James Harrop, Raja Rampersaud, Christopher M Bono, Ralf H Gahr

Department of Neurosurgery Faculty Papers

BACKGROUND: Considerable variability exists in clinical approaches to thoracolumbar fractures. Controversy in evaluation and nomenclature contribute to this confusion, with significant differences found between physicians, between different specialties, and in different geographic regions. A new classification system for thoracolumbar injuries, the Thoracolumbar Injury Severity Score (TLISS), was recently described by Vaccaro. No assessment of regional differences has been described. We report regional variability in use of the TLISS system between United States and non-US surgeons.

METHODS: Twenty-eight spine surgeons (8 neurosurgeons and 20 orthopedic surgeons) reviewed 56 clinical thoracolumbar injury case histories, which included pertinent imaging studies. Cases were classified …

A Risk Stratification Tool To Assess Commecial Influences On Continuing Medical Education, Barbara E. Barnes, Jeanne G. Cole, Catherine Thomas King, Rebecca Zukowski, Tracy Allgier-Baker, Doris Mcgartland Rubio, Luanne E. Thorndyke

Office of Continuing Medical Education

Introduction: Heightened concerns about industry influence on continuing medical education (CME) have prompted tighter controls on the management of commercial funding and conflict of interest. As a result, CME providers must closely monitor their activities and intervene if bias or noncompliance with accreditation standards is likely. Potential for industry influence can be difficult to assess at a stage in the planning process when mitigation strategies can assure balance and content validity. Few tools exist to aid providers in this regard.

Methods: A 12-item instrument was designed to assess risk for commercial influence on CME. To determine reliability and validity, a …

Turf Wars In Radiology: What Must Academic Radiology Do?, Vijay M. Rao, David C. Levin

Department of Radiology Faculty Papers

In a previous article in this series, we called upon private practice radiology groups to better support radiology research financially, but also pointed out that academic radiology must make some changes as well. In this article, we discuss those changes in detail. They include revising the structure of the radiology residency, changing the timing of the American Board of Radiology oral examinations, requiring that all residents receive research training, and emphasizing the value of clinical and translational research. The Society of Chairmen of Academic Radiology Departments (SCARD) needs to assume a leadership role in implementing these changes.

Does ‘Excessive’ Anticoagulation Predispose To Periprosthetic Infection?, Javad Parvizi, Elie Ghanem, Ashish Joshi, Peter F. Sharkey, William J. Hozack, Richard H. Rothman

Department of Orthopaedic Surgery Faculty Papers

Background
Although persistent drainage and hematoma formation are recognized risk factors for the development of periprosthetic infection, it is not known if excess anticoagulation is a predisposing factor.

Methods
We conducted a 2 to 1 case-control study with 78 cases who underwent revision for septic failure. The controls underwent the same index procedure but did not develop consequent infection. Patient comorbidities, medications, intraoperative, and postoperative factors were compared.

Results
Postoperative wound complications including development of hematoma and wound drainage were significant risk factors for periprosthetic infection. A mean international normalized ratio of greater than 1.5 was found to be more …

Phosphorylation-Induced Conformational Switching Of Cpi-17 Produces A Potent Myosin Phosphatase Inhibitor, Masumi Eto, Toshio Kitazawa, Fumiko Matsuzawa, Sei-Ichi Aikawa, Jason A. Kirkbride, Noriyoshi Isozumi, Yumi Nishimura, David L. Brautigan, Shin-Ya Ohki

Department of Molecular Physiology and Biophysics Faculty Papers

Phosphorylation of endogenous inhibitor proteins specific for type-1 Ser/Thr phosphatase (PP1) provides a mechanism for reciprocal coordination of kinase and phosphatase activities. Phosphorylation of Thr38 in the inhibitor protein CPI-17 transduces G-protein-mediated signaling into a > 1000-fold increase of inhibitory potency toward myosin phosphatase. We show here the solution NMR structure of phospho-T38-CPI-17 with r. m. s. d. of 0.36 ± 0.06 Å for the backbone secondary structure, which reveals how phosphorylation triggers a conformational change and exposes the PP1 inhibitory surface. This active conformation is stabilized by the formation of a hydrophobic core of intercalated side-chains, which is not formed …

Human Collagen Krox Up-Regulates Type I Collagen Expression In Normal And Scleroderma Fibroblasts Through Interaction With Sp1 And Sp3 Transcription Factors., Magdalini Kypriotou, Gallic Beauchef, Christos Chadjichristos, Russell Widom, Emmanuelle Renard, Sergio A. Jimenez, Joseph Korn, François-Xavier Maquart, Thierry Oddos, Otto Von Stetten, Jean-Pierre Pujol, Philippe Galéra

Department of Medicine Faculty Papers

Despite several investigations, the transcriptional mechanisms that regulate the expression of both type I collagen genes (COL1A1 and COL1A2) in either physiological or pathological situations, such as scleroderma, are not completely known. We have investigated the role of hc-Krox transcription factor on type I collagen expression by human dermal fibroblasts. hc-Krox exerted a stimulating effect on type I collagen protein synthesis and enhanced the corresponding mRNA steady-state levels of COL1A1 and COL1A2 in foreskin fibroblasts (FF), adult normal fibroblasts (ANF), and scleroderma fibroblasts (SF). Forced hc-Krox expression was found to up-regulate COL1A1 transcription through a -112/-61-bp sequence in FF, ANF, …

Stabilization Of Smar1 Mrna By Pga2 Involves A Stem Loop Structure In The 5' Utr, Lakshminarasimhan Pavritha, Shravanti Rampalli, Surajit Sinha, Kadreppa Sreenath, Richard G. Pestell, Samit Chattopadhyay

Department of Cancer Biology Faculty Papers

Prostaglandins are anticancer agents known to inhibit tumor cell proliferation both in vitro and in vivo by affecting the mRNA stability. Here we report that a MAR-binding protein SMAR1 is a target of Prostaglandin A2 (PGA2) induced growth arrest. We identify a regulatory mechanism leading to stabilization of SMAR1 transcript. Our results show that a minor stem and loop structure present in the 5' UTR of SMAR1 (1-UTR) is critical for nucleoprotein complex formation that leads to SMAR1 stabilization in response to PGA2. This results in an increased SMAR1 transcript and altered protein levels, that in turn causes downregulation of …

Time For An Active Antiviral Therapy For Hepatitis B: An Update On The Management Of Hepatitis B Virus Infection., Hee Bok Chae, Hie-Won Hann

Department of Medicine Faculty Papers

Significant advances in the management of chronic hepatitis B (CHB) have been made over the past decade. During this period we have witnessed improvements in survival as well as reduction of disease progression in CHB patients due to the introduction of effective antiviral therapy. The need for effective antiviral therapy is underscored by the results of the REVEAL-HBV study in which 3653 hepatitis B virus (HBV) carriers were followed over 12 year period. This study demonstrated that a persistently elevated serum HBV DNA level was the most important risk factor for the development of hepatocellular carcinoma (HCC). The ultimate goal …

Baseline Hbv Dna Level Is The Most Important Factor Associated With Virologic Breakthrough In Chronic Hepatitis B Treated With Lamivudine., Hee Bok Chae, Hie-Won Hann

Division of Gastroenterology and Hepatology Faculty Papers

Aim: To identify the factors associated with virologic breakthrough and to select a subgroup of patients who respond well to lamivudine without developing virologic breakthrough (VBT).

Methods: Of 79 patients who had received lamivudine therapy for 9-57 mo, 34 were HBeAg-positive and 45 were HBeAg-negative, 24 developed virologic breakthrough and 55 did not. Clinical and virologic factors were compared between the two groups.

Results: The median duration of therapy was 25 (9-57) mo. Virologic breakthrough was defined as a > 1 log HBV DNA increase following initial suppression. When several factors, including gender, duration of infection, baseline HBV DNA, and baseline …

Platelet Hyperreactivity: Predictive And Intrinsic Properties., Paul F. Bray

Cardeza Foundation for Hematologic Research

Platelet thrombi are central to the development of most vascular ischemic events. There is marked interindividual variation in platelet responsiveness, with some subjects displaying platelet hyperreactivity. An increasing number of reports indicate that there are laboratory measures of platelet function that predict clinical thrombotic events. Some, but not all, measures of platelet function are reproducible. Platelet hyperreactivity can be assessed with multiple stimuli in multiple assays and is more likely to be present in women and in subjects who have elevated fibrinogen levels.

A Second Large Plasmid Encodes Conjugative Transfer And Antimicrobial Resistance In O119:H2 And Some Typical O111 Enteropathogenic Escherichia Coli Strains, Adaobi I. Nwaneshiudu, Tania Mucci, Derek J. Pickard, Iruka N. Okeke

Student Papers, Posters & Projects

A novel and functional conjugative transfer system identified in O119:H2 enteropathogenic Escherichia coli (EPEC) strain MB80 by subtractive hybridization is encoded on a large multidrug resistance plasmid, distinct from the well-described EPEC adherence factor (EAF) plasmid. Variants of the MB80 conjugative resistance plasmid were identified in other EPEC strains, including the prototypical O111:NM strain B171, from which the EAF plasmid has been sequenced. This separate large plasmid and the selective advantage that it confers in the antibiotic era have been overlooked because it comigrates with the virulence plasmid on conventional gels.

Barriers To Recovery And Recommendations For Change: The Pennsylvania Consensus Conference On Psychiatry's Role., Joseph A. Rogers, Michael J. Vergare, Richard C. Baron, Mark S. Salzer

Department of Psychiatry and Human Behavior Faculty Papers

OBJECTIVE: Recovery has emerged over the past decade as a dominant theme in public mental health care.

METHODS: The 2006 Pennsylvania Consensus Conference brought together 24 community psychiatrists to explore the barriers they experienced in promoting recovery and their recommendations for change.

RESULTS: Twelve barriers were identified and classified into one of three categories: psychiatry knowledge, roles, and training; the need to transform public mental health systems and services; and environmental barriers to opportunity. Participants made 22 recommendations to address these barriers through changes in policies, programs, and psychiatric knowledge and practice.

CONCLUSIONS: The recommendations identify areas for change that …

Plant-Derived Epcam Antigen Induces Protective Anti-Cancer Response., Robert Brodzik, Sergei Spitsin, Max Golovkin, Katarzyna Bandurska, Carla Portocarrero, Monika Okulicz, Zenon Steplewski, Hilary Koprowski

Department of Cancer Biology Faculty Papers

Immunotherapy holds great promise for treatment of infectious and malignant diseases and might help to prevent the occurrence and recurrence of cancer. We produced a plant-derived tumor-associated colorectal cancer antigen EpCAM (pGA733) at high yields using two modern plant expression systems. The full antigenic domain of EpCAM was efficiently purified to confirm its antigenic and immunogenic properties as compared to those of the antigen expressed in the baculovirus system (bGA733). Recombinant plant-derived antigen induced a humoral immune response in BALB/c mice. Sera from those mice efficiently inhibited the growth of SW948 colorectal carcinoma cells xenografted in nude mice, as compared …

Comparison Of Eight Prosthetic Aortic Valves In A Cadaver Model, Benjamin A. Youdelman, Hitoshi Hirose, Harsh Jain, J. Yasha Kresh, John W.C. Entwhistle Iii, Andrew S. Wechsler

Department of Surgery Faculty Papers

OBJECTIVES: Proper valve selection is critical to ensure appropriate valve replacement for patients, because implantation of a small valve might place the patient at risk for persistent gradients. Labeled valve size is not the same as millimeter measure of prosthetic valve diameters or the annulus into which it will fit. Studies that use the labeled valve size in lieu of actual measured diameter in millimeters to compare different valves might be misleading. Using human cadaver hearts, we sized the aortic annulus with 8 commonly used prosthetic aortic valve sizers and compared the valves using geometric orifice area. This novel method …
