Isolated Laryngeal Leishmaniasis In Immunocompetent Patients: An Underdiagnosed Disease., Salvatore Cocuzza, Alessio Strazzulla, Marilia Rita Pinzone, Stefano Cosentino, Agostino Serra, Rosario Caltabiano, Salvatore Lanzafame, Bruno Cacopardo, Giuseppe Nunnari

Department of Microbiology and Immunology Faculty Papers

We describe a case of isolated primary laryngeal leishmaniasis in an immunocompetent Italian patient with a previous medical history negative for visceral or cutaneous leishmaniasis, presenting with hoarseness. We also summarize the epidemiological, clinical, and diagnostic features and the therapeutic management of other cases of laryngeal leishmaniasis in immunocompetent subjects, described in the literature. Considering the insidious and nonspecific clinical presentation, the increasing number of different forms of mild or underestimated immunosuppressive conditions, and the number of people travelling in endemic zones, along with the ability of Leishmania amastigotes to survive for a long period in the body, we believe …

Ddx5 Facilitates Hiv-1 Replication As A Cellular Co-Factor Of Rev., Xiuxia Zhou, Juan Luo, Lisa Mills, Shuangxin Wu, Ting Pan, Guannan Geng, Jim Zhang, Haihua Luo, Chao Liu, Hui Zhang

Department of Medicine Faculty Papers

HIV-1 Rev plays an important role in the late phase of HIV-1 replication, which facilitates export of unspliced viral mRNAs from the nucleus to cytoplasm in infected cells. Recent studies have shown that DDX1 and DDX3 are co-factors of Rev for the export of HIV-1 transcripts. In this report, we have demonstrated that DDX5 (p68), which is a multifunctional DEAD-box RNA helicase, functions as a new cellular co-factor of HIV-1 Rev. We found that DDX5 affects Rev function through the Rev-RRE axis and subsequently enhances HIV-1 replication. Confocal microscopy and co-immunoprecipitation analysis indicated that DDX5 binds to Rev and this …

Successful Identification Of Pathogens By Polymerase Chain Reaction (Pcr)-Based Electron Spray Ionization Time-Of-Flight Mass Spectrometry (Esi-Tof-Ms) In Culture-Negative Periprosthetic Joint Infection., Christina L Jacovides, Rachael Kreft, Bahar Adeli, Bryan Hozack, Garth D Ehrlich, Javad Parvizi

Rothman Institute Papers

BACKGROUND: The diagnosis of periprosthetic joint infection poses many challenges, one of which is the difficulty of isolating the infecting organism. Recently, a sophisticated modality (the Ibis Biosciences T5000 biosensor system) has been introduced that uses pan-domain primers in a series of polymerase chain reactions (PCRs) to identify and speciate essentially all bacteria and fungi as well as to identify key antibiotic resistance genes. We investigated the role of the Ibis in identifying infecting organisms in cases of known and suspected periprosthetic joint infection.

METHODS: Synovial fluid specimens were collected prospectively from eighty-two patients undergoing eighty-seven arthroplasty procedures (sixty-five knee …

Emil Theodor Kocher, M.D., And His Nobel Prize (1841-1917)., Zhi Ven Fong, B.S., Ernest L. Rosato, Md, Harish Lavu, Md, Charles J. Yeo, Md, Scott W. Cowan, Md

Department of Surgery Gibbon Society Historical Profiles

Major contributions to the advancement of surgery occurred at the turn of the 20th century. Theodor Billroth was in the midst of revolutionizing abdominal surgery, whereas Louis Pasteur and Joseph Lister were making landmark strides in antisepsis, forever changing the foundations of surgical thinking. Undoubtedly, Theodor Kocher’s (Fig. 1) exposure to these and other giants had a major influence on his career and contributed to his success and ascent as the first, and one of only 10, surgeons ever to be awarded the Nobel Prize in Medicine.

Common Respiratory Issues In Ambulatory Obstetrics., Kelly M Orzechowski, Richard C Miller

Department of Obstetrics and Gynecology Faculty Papers

This article reviews the diagnosis and management of the most common respiratory conditions complicating pregnancy--asthma and influenza. We also review strategies for smoking cessation in pregnancy as, in addition to exacerbating all other pulmonary conditions, smoking is the most modifiable risk factor for poor pregnancy outcome. Moreover, the obstetrician frequently encounters each of these conditions in the ambulatory setting. A thorough knowledge of the normal pregnancy-induced physiological respiratory changes combined with a comprehensive understanding of how to manage these conditions, will provide the obstetrician with the armamentarium needed to optimize health outcomes for mothers and their fetuses.

Stubborn, Persistent, Dangerous C.Difficile Infections. Is Improvement Possible?, Sara Townsend

Master of Science in Healthcare Quality and Safety Capstone Presentations

C.difficile also known as C.diff or CDI has developed into a dangerous infection for the United States’ health care system. While much work has been done to improve C.diff rates, health care teams have not been successful in reducing C.difficile infections. Many studies have focused on the mode of transmission of C.difficle, yet there still is not consensus on understanding how this infection is spread. Bryn Mawr Hospital, a community hospital in the suburbs of Philadelphia, Pa, has struggled to improve their C.diff rates like their peers throughout the country. While their infection rates for C.diff are …

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. …

Targeting Apoptosis For Optical Imaging Of Infection, Mathew L Thakur, Kaijun Zhang, Bishnuhari Paudyal, Devadhas Devakumar, Maria Y Covarrubias, Changpo Cheng, Brian D Gray, Eric Wickstrom, Koon Y Pak

Department of Radiology Faculty Papers

PURPOSE: Infection is ubiquitous and a major cause of morbidity and mortality. The most reliable method for localizing infection requires radiolabeling autologous white blood cells ex vivo. A compound that can be injected directly into a patient and can selectively image infectious foci will eliminate the drawbacks. The resolution of infection is associated with neutrophil apoptosis and necrosis presenting phosphatidylserine (PS) on the neutrophil outer leaflet. Targeting PS with intravenous administration of a PS-specific, near-infrared (NIR) fluorophore will permit localization of infectious foci by optical imaging.

METHODS: Bacterial infection and sterile inflammation were induced in separate groups (n = 5) …

Sex and gender differences influence the health and wellbeing of men and women. Although studies have drawn attention to observed differences between women and men across diseases, remarkably little research has been pursued to systematically investigate these underlying sex differences. Women continue to be underrepresented in clinical trials, and even in studies in which both men and women participate, systematic analysis of data to identify potential sex-based differences is lacking. Standards for reporting of clinical trials have been established to ensure provision of complete, transparent and critical information. An important step in addressing the gender imbalance would be inclusion of …

Chip Sequencing Of Cyclin D1 Reveals A Transcriptional Role In Chromosomal Instability In Mice., Mathew C Casimiro, Marco Crosariol, Emanuele Loro, Adam Ertel, Zuoren Yu, William Dampier, Elizabeth A Saria, Alex Papanikolaou, Timothy J Stanek, Zhiping Li, Chenguang Wang, Paolo Fortina, Sankar Addya, Aydin Tozeren, Erik S Knudsen, Andrew Arnold, Richard G Pestell

Kimmel Cancer Center Faculty Papers

Chromosomal instability (CIN) in tumors is characterized by chromosomal abnormalities and an altered gene expression signature; however, the mechanism of CIN is poorly understood. CCND1 (which encodes cyclin D1) is overexpressed in human malignancies and has been shown to play a direct role in transcriptional regulation. Here, we used genome-wide ChIP sequencing and found that the DNA-bound form of cyclin D1 occupied the regulatory region of genes governing chromosomal integrity and mitochondrial biogenesis. Adding cyclin D1 back to Ccnd1-/- mouse embryonic fibroblasts resulted in CIN gene regulatory region occupancy by the DNA-bound form of cyclin D1 and induction of CIN …
