Ewing's Sarcoma Arising From The Adrenal Gland In A Young Male: A Case Report, Muhammad Nauman Zahir, Tayyaba Zehra Ansari, Tariq Moatter, Wasim Memon, Shahid Pervez

Section of Haematology/Oncology

Background: Ewing's sarcoma uncommonly arises from extraosseous soft tissue or parenchymal organs. Primary adrenal Ewing's Sarcoma, although very rare, is extremely aggressive and commonly fatal.

CASE PRESENTATION: A 17 year old Pakistani male was referred to the outpatient oncology clinic at our center with a three month history of concomitant pain, swelling and dragging sensation in the right hypochondrium. Abdominal examination revealed a large, firm mass in the right hypochondrium extending into the right lumbar region and epigastrium. His genital exam was unremarkable and there were no stigmata of hepatic or adrenal disease.Computed tomography scans revealed a large peripherally …

Racial Differences In Human Platelet Par4 Reactivity Reflect Expression Of Pctp And Mir-376c., Leonard Edelstein, Lukas M Simon, Raúl Teruel Montoya, Michael Holinstat, Edward S Chen, Angela Bergeron, Xianguo Kong, Srikanth Nagalla, Narla Mohandas, David E Cohen, Jing-Fei Dong, Chad Shaw, Paul Bray

Racial differences in the pathophysiology of atherothrombosis are poorly understood. We explored the function and transcriptome of platelets in healthy black (n = 70) and white (n = 84) subjects. Platelet aggregation and calcium mobilization induced by the PAR4 thrombin receptor were significantly greater in black subjects. Numerous differentially expressed RNAs were associated with both race and PAR4 reactivity, including PCTP (encoding phosphatidylcholine transfer protein), and platelets from black subjects expressed higher levels of PC-TP protein. PC-TP inhibition or depletion blocked PAR4- but not PAR1-mediated activation of platelets and megakaryocytic cell lines. miR-376c levels were differentially expressed by race and …

Multicenter Study Of High-Dose Daptomycin For Treatment Of Enterococcal Infections, Anthony M. Casapao, Ravina Kullar, Susan L. Davis, Donald P. Levine, Jing J. Zhao, Brian A. Potoski, Debra A. Goff, Christopher W. Crank, John Segreti, George Sakoulas, Sara E. Cosgrove, Michael J. Rybak

Enterococci are among the leading pathogens isolated in hospital-acquired infections. Current antimicrobial options for vancomycin-resistant enterococci (VRE) are limited. Prior data suggests that daptomycin > 6mg/kg/day may be used to treat enterococcal infections. We retrospectively evaluated the effectiveness and safety of high-dose daptomycin (HD-daptomycin) therapy (> 6 mg/kg) in a multicenter cohort of adult patients with enterococcal infections to describe the characteristics and outcomes. Two-hundred and forty-five patients were evaluated. Enterococcus faecium was identified in 175 (71%), followed by 49 (20%) Enterococcus faecalis and 21 (9%) Enterococcus spp., overall 204 (83%) were VRE. Enterococcal infections included bacteremia (173, 71%), intra-abdominal (35, …

Erosive Arthritis And Hepatic Granuloma Formation Induced By Peptidoglycan Polysaccharide In Rats Is Aggravated By Prasugrel Treatment., Analia E Garcia, Mario C Rico, Elisabetta Liverani, Raul A Dela Cadena, Paul F. Bray, Satya P Kunapuli

Cardeza Foundation for Hematologic Research

Administration of the thienopyridine P2Y12 receptor antagonist, clopidogrel, increased the erosive arthritis induced by peptidoglycan polysaccharide (PG-PS) in rats or by injection of the arthritogenic K/BxN serum in mice. To determine if the detrimental effects are caused exclusively by clopidogrel, we evaluated prasugrel, a third-generation thienopyridine pro-drug, that contrary to clopidogrel is mostly metabolized into its active metabolite in the intestine. Prasugrel effects were examined on the PG-PS-induced arthritis rat model. Erosive arthritis was induced in Lewis rats followed by treatment with prasugrel for 21 days. Prasugrel treated arthritic animals showed a significant increase in the inflammatory response, compared with …

A 2-Step Approach To Myeloablative Haploidentical Stem Cell Transplantation With Optimized T-Cell Dosing: Early Immune Reconstitution Leads To Better Outcomes, Sameh Gaballa, Onder Alpdogan, Matthew Carabasi, Joanne Filicko, Margaret Kasner, Ubaldo E. Martinez-Outshoorn, Md, John L Wagner, Mark Weiss, Neal Flomenberg, Delores Grosso

Department of Medical Oncology Faculty Papers

We developed a 2-step approach to myeloablative haploidentical HSCT in which patients receive a large fixed dose of cyclophosphamide (CY)-tolerized T cells separately frm the HSC infusion in the hopes of accelerating post HSCT immune reconstitution (IR). The uniformity of the T cell dosing facilitates comparison of patients without (low risk) and with (high risk) active malignancy at HSCT to ascertain the impact of disease status at HSCT on IR with fewer confounding effects from conditioning or T cell dosing.

Transcranial Sonothrombolysis Using High-Intensity Focused Ultrasound: Impact Of Increasing Output Power On Clot Fragmentation, Golnaz Ahadi, Christian S. Welch, Michele J. Grimm, David J. Fisher, Eyal Zadicario, Karin Ernström, Arne H. Voie, Thilo Hölscher

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

The primary goal of this study was to investigate the relationship between increasing output power levels and clot fragmentation during high-intensity focused ultrasound (HIFU)-induced thrombolysis.

Methods

A HIFU headsystem, designed for brain applications in humans, was used for this project. A human calvarium was mounted inside the water-filled hemispheric transducer. Artificial thrombi were placed inside the skull and located at the natural focus point of the transducer. Clots were exposed to a range of acoustic output power levels from 0 to 400 W. The other HIFU operating parameters remained constant. To assess clot fragmentation, three filters of different …

BACKGROUND: Human blood platelets are essential to maintaining normal hemostasis, and platelet dysfunction often causes bleeding or thrombosis. Estimates of genome-wide platelet RNA expression using microarrays have provided insights to the platelet transcriptome but were limited by the number of known transcripts. The goal of this effort was to deep-sequence RNA from leukocyte-depleted platelets to capture the complex profile of all expressed transcripts.

RESULTS: From each of four healthy individuals we generated long RNA (≥40 nucleotides) profiles from total and ribosomal-RNA depleted RNA preparations, as well as short RNA (<40 >nucleotides) profiles. Analysis of ~1 billion reads revealed that coding …

Department of Pathology and Laboratory Medicine

Objective: The objective of this study was to evaluate the frequency and outcome of graft versus host disease after stem cell transplantation for various haematological disorders in Pakistan.
Materials and Methods: Pretransplant workup of the patient and donor was performed. Mobilization was done with G-CSF 300 mu g twice daily for five day. Standard GvHD prophylaxis was done with methotrexate 15mg/m(2) on day +1 followed by 10mg/m(2) on days +3 and +6 and cyclosporine. Grading was done according to the Glucksberg classification.
Results: A total of 153 transplants were done from April 2004 to December 2011. Out of these were …
