Department of Medicine Faculty Papers

OBJECTIVES: We analyzed the infection burden associated with the implantation of cardiac implantable electrophysiological devices (CIEDs) in the United States for the years 1993 to 2008.

BACKGROUND: Recent data suggest that the rate of infection following CIED implantation may be increasing.

METHODS: The Nationwide Inpatient Sample (NIS) discharge records were queried between 1993 and 2008 using the 9th Revision of the International Classification of Diseases (ICD-9-CM). CIED infection was defined as either: 1) ICD-9 code for device-related infection (996.61) and any CIED procedure or removal code; or 2) CIED procedure code along with systemic infection. Patient health profile was evaluated …

Capacity Building For Participatory Health Services Research In Housing First, Lara Carson Weinstein, Md

Department of Family & Community Medicine Presentations and Grand Rounds

Background:

Pathways to Housing ends chronic homelessness for individuals with serious mental illness (SMI) by providing housing first, and then combining that housing with supportive treatment services in the area of mental and physical health, substance abuse, education, and employment. Housing is provided in apartments scattered throughout a community. This "scattered site" model fosters a sense of home and self-determination, and it helps speed client's reintegration into the community. The Pathways model has been remarkable successful in addressing chronic homelessness.

Research Question

What are the chronic physical disease self management support needs of Pathways to Housing clients?

Primary Provider Beliefs And Practice Patterns Contribute To The Lack Of Hiv/Hcv Coinfected Patients Undergoing Liver Transplantation In The United States, Jonathan M. Fenkel, Md, Victor J. Navarro, Md

Division of Gastroenterology and Hepatology Faculty Papers

Conclusions:

1. The majority of primary providers were ambivalent toward or against LT for HIV/HCV coninfected patients.

2. Half of all respondents were unlikely to refer cirrhotic coinfected patients for LT evaluation.

3. HIV specialists were significantly more likely to believe transplant should be offered, but reported no difference in likelihood of LT referral.

4. These findings suggest that primary provider beliefs and self-reported practice patterns may partially explain the paucity of coinfected US liver transplant recipients.

Meningitis Presenting As Depression: A Case Report, Karl Doghramji, Md

Jefferson Journal of Psychiatry

The relationship between psychiatric and medical illness has long been recognized by clinicians. Of special importance to psychiatrists are the diagnostic dilemmas posed by medical illnesses presenting as psychiatric disorders. In a review of recent studies, LaBruzza found that "at least one out of every twenty patients receiving an initial psychiatric evaluation may have an underlying medical illness which accounts for the psychiatric symptoms." This was especially true with inpatients, where between 5% and 30% of patients, with a weighted average of 12%, had medical illnesses accounting for their psychiatric complaints 11). One medical illness which can resemble psychiatric illness …

Attention Deficit Disorder, Residual Type- A Case Study, James Stanch, Md

Jefferson Journal of Psychiatry

The syndrome of Minimal Brain Dysfunction (MBD) in children has been well described by a number of authors. Such children were first described in 1941 by Werner and Strauss(1) who made a distinction between brain injury and -simple- mental retardation. In the past such terms as Hyperactive Child Syndrome, Minimal Brain Damage, and Hyperkinetic Behavior Syndrome have been used to describe this syndrome.

Interpersonal Relationships As Sources Of Medical Student Stress, Beverly Jones, Md

Jefferson Journal of Psychiatry

Introduction

The issue of physician impairment, that is , decreased ability or quality of functioning due to intemperate use of drugs or alcohol, emotional or psychiatric dysfunction, has recently received attention (1,5) . Studies have indicated the risks physicians face of substance abuse problems(6,7), marital discord(8,9), suicide (lO,ll), and psychiatric problems (l2-14). studies have also addressed the difficulties faced by medical students (15-20).

A group of medical students at the University of North Carolina came together to investigate the subject of medical student impairment . A survey was constructed in order to ascertain the sources of stress in medical school. …

Olfaction And Sexuality, Michael Buxbaum, Md

Jefferson Journal of Psychiatry

A patient who describes himself as "sanitary" told me of his concern with odors. Whenever he thinks about establishing a sexual relationship , he develops a fear that his partner may smell offensive, especially around her genital area. He describes signs and symptoms of sympathetic overactivity when he engages in foreplay, and is afraid that he might be impotent if he smells anything offensive. In fact, he has to insert a finger into his partner's vagina during foreplay, to test the nature of the odor. He feels relieved when the smell is neutral or perfumed, and demonstrates enhanced sexual performance. …

With this issue, The Jefferson Journal of Psychiatry , a Resident Publication, comes into being.

The purpose of this journal is to provide a forum for the presentation of ideas, data, and discussion. We are trying to give residents a setting in which to communicate in a way more formal than the seminars of residency training, but less forbidding than national journals.

Religious Experiences Shrink Part Of The Brain, Andrew Newberg, M.D.

Marcus Institute of Integrative Health Faculty Papers

A study links life-changing religious experiences, like being born again, with atrophy in the hippocampus.

The article, “Religious factors and hippocampal atrophy in late life,” by Amy Owen and colleagues at Duke University represents an important advance in our growing understanding of the relationship between the brain and religion. The study showed greater atrophy in the hippocampus in individuals who identify with specific religious groups as well as those with no religious affiliation. It is a surprising result, given that many prior studies have shown religion to have potentially beneficial effects on brain function, anxiety, and depression.

Oncologic Efficacy Is Not Compromised, And May Be Improved With Minimally Invasive Esophagectomy., Adam C Berger, Aaron Bloomenthal, Benny Weksler, Nathaniel Evans, Karen A Chojnacki, Charles J Yeo, Ernest L Rosato

Department of Surgery Faculty Papers

BACKGROUND: Major morbidity and mortality rates continue to be high in large series of transthoracic esophagectomies. Minimally invasive approaches are being increasingly used. We compare our growing series of minimally invasive (combined thoracoscopic and laparoscopic) esophagectomies (MIEs) with a series of open transthoracic esophagectomies.

STUDY DESIGN: We identified 65 patients who underwent an MIE with thoracoscopy/laparotomy (n = 11), Ivor Lewis (n = 2), or 3-hole approach (n = 52). These patients were compared with 53 patients who underwent open Ivor-Lewis esophagectomy (n = 15) or 3-hole esophagectomy (n = 38) over the past 10 years.

RESULTS: The MIE and …

Ercc1 And Rrm1 As Predictors Of Survival And Response In Pancreatic Ductal Adenocarcinoma Treated With Gemcitabine-Based Chemotherapy, Thomas Holdbrook, Kathleen D. Danenberg, Suneeta Satti, Jessica Kline, Charles J. Yeo, Jonathan R. Brody, Peter Mccue, Agnieszka K. Witkiewicz

Department of Surgery Faculty Papers

Conclusion:

In this study, we used RT-PCR and IHC to analyze RRM1 and ERCC1 mRNA and protein expression in PDA specimens. PDA patients with low expression of RRM1 by IHC derived benefit from gemcitabine-based chemotherapy. Assessment of RRM1 mRNA expression was limited by the small sample size. Low ERCC1 expression by RT-PCR was associated with a 2.5 times higher risk of mortality than high expression (p=0.031). There was no association between ERCC1 expression by IHC and survival; however, agreement between mRNA and protein expression was poor for ERCC1. This study demonstrates the ERCC1 and RRM1 expression have an impact on …

Expression Of Aldehyde Dehydrogenase In Dysplastic Lesions Arising From Inflammatory Bowel Disease, Adam D. Toll, Bruce M. Boman, Juan P. Palazzo

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Conclusion: Our study demonstrates ALDH1 is significantly expressed in dysplatic lesions arising from IBD. ALDH1-expression in cancer stem cells suggest an important causative role in the progression to cancer in IBD. Although we found high sensitivity for dysplasia, the specificity was poor. In addition to neoplasia, ALDH1-expressing stem cells proliferate in response to chronic inflammation, accounting for the cases of inflammatory atypia with positive ALDHI1 expression.

Improving Function In Age-Related Macular Degeneration: Design And Methods Of A Randomized Clinical Trial., Barry W Rovner, Robin J Casten, Mark T Hegel, Robert W Massof, Benjamin E Leiby, William S Tasman

Department of Psychiatry and Human Behavior Faculty Papers

Age-Related Macular Degeneration (AMD) is the leading cause of severe vision loss in older adults and impairs the ability to read, drive, and live independently and increases the risk for depression, falls, and earlier mortality. Although new medical treatments have improved AMD's prognosis, vision-related disability remains a major public health problem. Improving Function in AMD (IF-AMD) is a two-group randomized, parallel design, controlled clinical trial that compares the efficacy of Problem-Solving Therapy (PST) with Supportive Therapy (ST) (an attention control treatment) to improve vision function in 240 patients with AMD. PST and ST therapists deliver 6 one-hour respective treatment sessions …

Implementing Integrated Primary And Behavioral Healthcare Within A Housing First Program, Lara C. Weinstein, Md, Benjamin Henwood, Lcsw

Department of Family & Community Medicine Presentations and Grand Rounds

At Pathways to Housing-Philadelphia, mental health services to support consumers' independent living are delivered through Assertive Community Treatment (ACT) teams. ACT is an evidence-based mental health intervention known to reduce psychiatric hospitalization and increase housing stability. ACT team members include social workers, substance abuse, counselors, nurses, and psychiatrists, with ideal staff to client ratios of 1 to 10. Through a novel collaboration between the program and the Deparment of Family and Community Medicine at Thomas Jefferson University, a primary-care physician was embedded into the ACT services to form an integrated health-care team.

The Pulmonologist's Role In Caring For Pregnant Women With Regard To The Reproductive Risks Of Diagnostic Radiological Studies Or Radiation Therapy., Robert Brent

Department of Pediatrics Faculty Papers

Radiography of the chest, head, neck, teeth, or extremity exposes the embryo or ovary to insignificant exposures of radiation except when radionuclides are utilized. In some instances, there is no exposure at all. Pulmonologists are fortunate with regard to the specific studies they request to provide clinical care because most of the diagnostic tests do not directly expose the uterus (embryo) or ovary. This article discusses radiation risks and their evaluation and pregnancy-related issues in diagnostic radiological studies.

Universal Or Indicated Screening In Primary Care?, Matthew Wintersteen, Md

Department of Psychiatry and Human Behavior Faculty Papers

To the Editor: In the November 2010 issue, Schmitt and colleagues (1) reported that the duration of visits increased when depression screening was conducted in primary care. This report is timely given recent recommendations for both adult and pediatric screening for depression in primary care. Schmitt and colleagues examined data representative of more than 641 million primary care visits in2005–2007 and found that when depression screening was documented in patients’ records, physicians’ time with patients increased significantly.

Apotransferrin Protects Cortical Neurons From Hemoglobin Toxicity, Jing Chen-Roetling, Lifen Chen, Raymond F. Regan

Department of Emergency Medicine Faculty Papers

The protective effect of iron chelators in experimental models of intracerebral hemorrhage suggests that nonheme iron may contribute to injury to perihematomal cells. Therapy with high affinity iron chelators is limited by their toxicity, which may be due in part to sequestration of metals in an inaccessible complex. Transferrin is unique in chelating iron with very high affinity while delivering it to cells as needed via receptor-mediated endocytosis. However, its efficacy against iron-mediated neuronal injury has never been described, and was therefore evaluated in this study using an established cell culture model of hemoglobin neurotoxicity. At concentrations similar to that …

Department of Urology Faculty Papers

Purpose: Data regarding the treatment of ureteropelvic junction obstruction (UPJO) in horseshoe kidneys are limited. We performed a retrospective analysis of our experience with minimally invasive treatment of UPJO in patients with this anomaly. Methods: Between March of 1996 and March 2008, 9 patients with horseshoe kidneys were treated for UPJO at our institution. Of these patients, 6 were managed with retrograde endopyelotomy, 2 with laparoscopic pyeloplasty, and one by robotic pyeloplasty. Outcomes of these procedures were retrospectively reviewed. Results: A total of nine patients were available for analysis. Four of six patients who underwent endopyelotomy had available follow-up, with …

Basal Internal Anal Sphincter Tone, Inhibitory Neurotransmission, And Other Factors Contributing To The Maintenance Of High Pressures In The Anal Canal, S. Rattan, J. Singh

Division of Gastroenterology and Hepatology Faculty Papers

Maintenance of the basal tone in the internal anal sphincter (IAS) is critical for rectoanal continence. Effective evacuation requires a fully functional rectoanal inhibitory reflex (RAIR)-mediated relaxation of the IAS via inhibitory neurotransmission (INT). Systematic studies examining the nature of the INT in different species have identified nitric oxide (NO) as the major inhibitory neurotransmitter. However, other mediators such as vasoactive intestinal polypeptide (VIP), ATP, and carbon monoxide (CO) may also play species-specific role under certain experimental conditions. Measurements of the intraluminal pressures in the IAS along with the force of the isolated IAS tissues are the mainstay in the …

Ratliff, Md, Stavropoula L. Tjoumakaris, Brian Frank, D. Greg Anderson, M.D., Todd Albert, Md, Alexander R. Vaccaro, Md, Phd

Department of Orthopaedic Surgery Faculty Papers

Study Design. Retrospective. Objective. With approximately 10,000 new spinal cord injury (SCI) patients in the United States each year, predicting public health outcomes is an important public health concern. Combining all regions of the spine in SCI trials may be misleading if the lumbar and sacral regions (conus) have a neurologic improvement at different rates than the thoracic or thoracolumbar spinal cord.

Summary of Background Data. Over a 10-year period between January 1995 to 2005, 1746 consecutive spinal injured patients were seen, evaluated, and treated through a level 1 trauma referral center. A retrospective analysis was performed on 150 patients …
