A Prospective Observational Study Of Mycophenolate Mofetil Treatment In Progressive Diffuse Cutaneous Systemic Sclerosis Of Recent Onset., Fabian A. Mendoza, Md, Sarah J. Nagle, Jason B. Lee, Md, Sergio A. Jimenez

Jefferson Institute of Molecular Medicine Papers and Presentations

OBJECTIVE: A prospective observational study of mycophenolate mofetil (MMF) treatment in patients with diffuse progressive cutaneous systemic sclerosis (SSc) of recent onset.

METHODS: Twenty-five previously untreated consecutive patients with recent-onset (< 24 mo) diffuse progressive cutaneous SSc received MMF as the only disease-modifying therapy. Modified Rodnan skin score (mRSS) and affected body surface area (BSA) were compared from initiation of MMF to study end. Pulmonary function tests performed at the same institution before therapy and at study end were available in 15 patients. Histopathology and real-time PCR assessment of fibrosis-related gene expression were performed before and after treatment in skin biopsies from 3 patients.

RESULTS: At 18.2 ± 8.73 months of MMF therapy (median 2000 mg/day) the mRSS decreased from 24.56 ± 8.62 to 14.52 ± 10.9 (p = 0.0004) and the affected BSA from 36% ± 16% to 14% ± 13.3% (p = 0.00001). Pulmonary function tests remained stable from initiation of MMF to the end of the study. Skin histopathology showed a remarkable reduction in accumulation of fibrotic tissue. Real-time PCR …

Community-Based Partnerships For Improving Chronic Disease Management, James Plumb, Laura Carson Weinsten, Rickie Brawer, Kevin Scott

Department of Family & Community Medicine Faculty Papers

With the growing burden of chronic disease, the medical and public health communities are re-examining their roles and opportunities for more effective prevention and clinical interventions. The potential to significantly improve chronic disease prevention and have an impact on morbidity and mortality from chronic conditions is enhanced by adopting strategies that incorporate a social ecology perspective, realigning the patient-physician relationship, integrating population health perspectives into the Chronic Care Model, and effectively engaging communities using established principles of community engagement.

Revision Total Knee Arthroplasty: Infection Should Be Ruled Out In All Cases, Mohammad R. Rasouli, Armin Aalami Harandi, Bahar Adeli, James J. Purtill, Javad Parvizi

Rothman Institute Papers

We hypothesized that some aseptic revision total knee arthroplasty failures are indeed caused by occult infection. This prospective study recruited 65 patients undergoing revision total knee arthroplasty. The mean follow-up period was 19 months. Collected synovial fluid was analyzed by Ibis T5000 biosensor (Abbott Molecular Inc, Ill; a multiplex polymerase chain reaction technology). Cases were considered as infected or aseptic based on the surgeon's judgment and Ibis findings. Based on Ibis biosensor, 17 aseptic cases were indeed infected that had been missed. Of these 17 cases, 2 developed infection after the index revision. A considerable number of so-called aseptic failures …

Phosphorylation Of Vasodilator-Stimulated Phosphoprotein Ser239 Suppresses Filopodia And Invadopodia In Colon Cancer., David S Zuzga, Joshua Pelta-Heller, Peng Li, Alessandro Bombonati, Scott A Waldman, Giovanni Mario Pitari

Department of Pharmacology and Experimental Therapeutics Faculty Papers

In colorectal cancer, the antitumorigenic guanylyl cyclase C (GCC) signalome is defective reflecting ligand deprivation from downregulation of endogenous hormone expression. Although the proximal intracellular mediators of that signal transduction system, including cyclic guanosine monophosphate (cGMP) and cGMP-dependent protein kinase (PKG), are well characterized, the functional significance of its distal effectors remain vague. Dysregulation of ligand-dependent GCC signaling through vasodilator-stimulated phosphoprotein (VASP), an actin-binding protein implicated in membrane protrusion dynamics, drastically reduced cGMP-dependent VASP phosphorylation levels in colorectal tumors from patients. Restoration of cGMP-dependent VASP phosphorylation by GCC agonists suppressed the number and length of locomotory (filopodia) and invasive (invadopodia) …

Effect Of Oxidative Stress On Protein Tyrosine Phosphatase 1b In Scleroderma Dermal Fibroblasts., Pei-Suen Tsou, Nadine N. Talia, Adam J. Pinney, Ann Kendzicky, Sonsoles Piera-Velazquez, Sergio A. Jimenez, James R. Seibold, Kristine Phillips, Alisa E Koch

Department of Dermatology and Cutaneous Biology Faculty Papers

OBJECTIVE: Platelet-derived growth factor (PDGF) and its receptor, PDGFR, promote fibrosis in systemic sclerosis (SSc; scleroderma) dermal fibroblasts, and such cells in scleroderma skin lesions produce excessive reactive oxygen species (ROS). PDGFR is phosphorylated upon PDGF stimulation, and is dephosphorylated by protein tyrosine phosphatases (PTPs), including PTP1B. This study was undertaken to determine whether the thiol-sensitive PTP1B is affected by ROS in SSc dermal fibroblasts, thereby enhancing the phosphorylation of PDGFR and synthesis of type I collagen. This study also sought to investigate the effect of a thiol antioxidant, N-acetylcysteine (NAC), in SSc.

METHODS: Fibroblasts were isolated from the skin …

Does The Load-Sharing Classification Predict Ligamentous Injury, Neurological Injury, And The Need For Surgery In Patients With Thoracolumbar Burst Fractures?: Clinical Article., Kristen Radcliff, Christopher K Kepler, Todd A Rubin, Motasem Maaieh, Alan S Hilibrand, James Harrop, Jeffrey A Rihn, Todd J Albert, Alexander R Vaccaro

Department of Orthopaedic Surgery Faculty Papers

OBJECT: The load-sharing score (LSS) of vertebral body comminution is predictive of results after short-segment posterior instrumentation of thoracolumbar burst fractures. Some authors have posited that an LSS > 6 is predictive of neurological injury, ligamentous injury, and the need for surgical intervention. However, the authors of the present study hypothesized that the LSS does not predict ligamentous or neurological injury.

METHODS: The prospectively collected spinal cord injury database from a single institution was queried for thoracolumbar burst fractures. Study inclusion criteria were acute (< 24 hours) burst fractures between T-10 and L-2 with preoperative CT and MRI. Flexion-distraction injuries and pathological fractures were excluded. Four experienced spine surgeons determined the LSS and posterior ligamentous complex (PLC) integrity. Neurological status was assessed from a review of the medical records.

RESULTS: Forty-four patients were included in the study. There were 4 patients for whom all observers …

Resolution Of Bilateral Ptosis After Reduction Of Unilaterally Elevated Intraocular Pressure In A Child With Axenfeld-Reiger Spectrum Disorder., Ketki Soin, Alex V. Levin

Wills Eye Hospital Papers

We report a 9-month-old boy with bilateral pseudoptosis associated with elevated IOP. The patient had previously undergone bilateral trabeculectomies and Ahmed tube placement and right cataract extraction and penetrating keratoplasty. At presentation, the right eye IOP was 24 mm Hg and the left eye IOP was 32 mm Hg. Approximately 2 weeks after dorzolamide was added to the treatment regimen for the left eye, the mother reported that the ptosis had resolved. We suggest several explanations for the resolution of the ptosis.

Nociceptive Neuropeptide Increases And Periorbital Allodynia In A Model Of Traumatic Brain Injury., Melanie B. Elliott, Michael L. Oshinsky, Peter S. Amenta, Olatilewa Awe, Jack I. Jallo

Department of Neurosurgery Faculty Papers

OBJECTIVE: This study tests the hypothesis that injury to the somatosensory cortex is associated with periorbital allodynia and increases in nociceptive neuropeptides in the brainstem in a mouse model of controlled cortical impact (CCI) injury.

METHODS: Male C57BL/6 mice received either CCI or craniotomy-only followed by weekly periorbital von Frey (mechanical) sensory testing for up to 28 days post-injury. Mice receiving an incision only and naïve mice were included as control groups. Changes in calcitonin gene-related peptide (CGRP) and substance P (SP) within the brainstem were determined using enzyme-linked immunosorbent assay and immunohistochemistry, respectively. Activation of ionized calcium-binding adaptor molecule-1-labeled …

Malignant Peripheral Nerve Sheath Tumor (Mpnst): An Overview With Emphasis On Pathology, Imaging And Management Strategies, Timothy C. Beer

Department of Neurosurgery Faculty Papers

Presentation: 20 slides

MPNSTs are rare malignancies that are classically associated with pre-existing plexiform neurofibromas in neurofibromatosis type 1 (NF-1) patients, but also occur in association with radiation as well as sporadically in patients with no known risk factors. The typical presentation of sporadic MPNST is a new painless enlarging mass. The typical presentation of MPNST in an NF-1 patient is rapid enlargement or new onset of pain associated with a pre-existing plexiform neurofibroma. Although both MPNST and benign neurofibromas share in common the absence of neurofibromin function due to loss of both NF-1 alleles, malignant transformation to MPNST requires …

Narrative Health Communication And Behavior Change: The Influence Of Exemplars In The News On Intention To Quit Smoking., Hyun Suk Kim, Cabral A. Bigman, Amy E. Leader, Caryn Lerman, Joseph N. Cappella

Department of Medical Oncology Faculty Papers

This study investigated psychological mechanisms underlying the effect of narrative health communication on behavioral intention. Specifically, the study examined how exemplification in news about successful smoking cessation affects recipients' narrative engagement, thereby changing their intention to quit smoking. Nationally representative samples of U.S. adult smokers participated in 2 experiments. The results from the 2 experiments consistently showed that smokers reading a news article with an exemplar experienced greater narrative engagement compared to those reading an article without an exemplar. Those who reported more engagement were in turn more likely to report greater smoking cessation intentions.

Proline-Rich Tyrosine Kinase 2 (Pyk2) Regulates Igf-I-Induced Cell Motility And Invasion Of Urothelial Carcinoma Cells, Marco Genua, Shi-Qiong Xu, Simone Buraschi, Stephen C. Peiper, Leonard G. Gomella, Antonio Belfiore, Renato V. Iozzo, Andrea Morrione

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

The insulin-like growth factor receptor I (IGF-IR) plays an essential role in transformation by promoting cell growth and protecting cancer cells from apoptosis. We have recently demonstrated that the IGF-IR is overexpressed in invasive bladder cancer tissues and promotes motility and invasion of urothelial carcinoma cells. These effects require IGF-I-induced Akt- and MAPK-dependent activation of paxillin. The latter co-localizes with focal adhesion kinases (FAK) at dynamic focal adhesions and is critical for promoting motility of urothelial cancer cells. FAK and its homolog Proline-rich tyrosine kinase 2 (Pyk2) modulate paxillin activation; however, their role in regulating IGF-IR-dependent signaling and motility in …

Periprosthetic Joint Infection: Are Patients With Multiple Prosthetic Joints At Risk?, S Mehdi Jafari, David S Casper, Camilo Restrepo, Benjamin Zmistowski, Javad Parvizi, Peter F Sharkey

Rothman Institute Papers

Patients who present with a periprosthetic joint infection in a single joint may have multiple prosthetic joints. The risk of these patients developing a subsequent infection in another prosthetic joint is unknown. Our purposes were (1) to identify the risk of developing a subsequent infection in another prosthetic joint and (2) to describe the time span and organism profile to the second prosthetic infection. We retrospectively identified 55 patients with periprosthetic joint infection who had another prosthetic joint in place at the time of presentation. Of the 55 patients, 11 (20%) developed a periprosthetic joint infection in a second joint. …

Present studies were performed to develop human IAS smooth muscle reconstructs with functional and molecular attributes similar to the intact human IAS Smooth muscle (SM).

Effect Of Pooled Human Intravenous Globulin (Ivig) On The Reversal Of Cholinergic Inhibition Of Smooth Muscle By Immunoglobulins (Iggs) From Patients With Scleroderma (Ssc), Jagmohan Singh, Vaibhav Mehendiratta, Sergio A. Jimenez, Sidney Cohen, Anthony J. Dimarino, Satish Rattan

Division of Gastroenterology and Hepatology Faculty Papers

Poster presented at: Digestive Disease Week (DDW) International meeting in San Diego, California.

Backgrounds and Aims:

The gastrointestinal (GI) tract is the most common internal organ system affected in SSc. We and others have shown before that the SSc immunoglobulins (IgGs) cause selective blockade of muscarinic type-3 cholinergic (M3-R) in the GI tract. Presently, there is no effective treatment for SSc although numerous cytotoxic and immunomodulatory agents have been employed with limited success and are marred with serious side effects. Present studies investigated the reversibility of SScIgGs-caused M3-R blockade by the pooled Intravenous immunoglobulins (IVIG).
