Defining Bone Health And Fracture Risk In West Virginia: The World Health Organization Frax® Assessment Tool, Franklin D. Shuler Md, Jacob Conjeski Md

Orthopaedics

This article highlights the expanding burden of osteoporosis in West Virginia. WV ranks second nationally in the percentage of its population that is ≥ 65 years of age. Our older population increases the risk of osteoporosis and fracture; the most recent data indicates that 77% of our women age 50 and older have osteoporosis or low bone mass. The lifetime risk of osteoporotic related fracture is alarming and occurs in 50% of females and 25% of males age 50 and older. The risk of osteoporosis related hip fracture in women is equal to the combined risk of breast, uterine or …

Malignant Psoas Abscess Or Pseudomyxoma Extraperitonei, Amber Mehmood, Kiran Ejaz, Turab Ibrahim Pishori

Department of Emergency Medicine

Primary adenocarcinoma of appendix is an uncommon gastrointestinal malignancy. Similarly, Psoas abscess is an entity, which sometimes requires extensive work-up to reach a diagnosis. Combined presentation of these two rare conditions is not only exceptional, but also diagnostically challenging. We present a case of a lady who presented with recurrent UTI secondary to right sided ureteric obstruction, referred right hip joint pain resulting from a Psoas abscess, which eventually turned out to be a consequence of metastatic adenocarcinoma of appendix, causing pseudomyxoma extraperitonei, with simultaneous intraperitoneal deposits.

Dynamic Alteration Of Adiponectin/Adiponectin Receptor Expression And Its Impact On Myocardial Ischemia/Reperfusion In Type 1 Diabetic Mice., Yanzhuo Ma, Yi Liu, Shaowei Liu, Yan Qu, Rutao Wang, Chenhai Xia, Haifeng Pei, Kun Lian, Tao Yin, Xiaoyan Lu, Lu Sun, Lu Yang, Yanjie Cao, Wayne Bond Lau, Erhe Gao, Haichang Wang, Ling Tao

Department of Emergency Medicine Faculty Papers

The present study determined the dynamic change of adiponectin (APN, a cardioprotective adipokine), its receptor expression, and their impact upon myocardial ischemia/reperfusion (MI/R) injury during type 1 diabetes mellitus (T1DM) progression, and involved underlying mechanisms. Diabetic state was induced in mice via multiple intraperitoneal injections of low-dose streptozotocin. The dynamic change of plasma APN concentration and cardiac APN receptor-1 and -2 (AdipoR1/2) expression were assessed immediately after diabetes onset (0 wk) and 1, 3, 5, and 7 wk thereafter. Indicators of MI/R injury (infarct size, apoptosis, and LDH release) were determined at 0, 1, and 7 wk of DM duration. …

The Role Of Computed Tomography For Identifying Mechanical Bowel Obstruction In A Pakistani Population, Omair Shakil, Syed Nabeel Zafar, Ziaur Rehman, Sarah Saleem, Rehmatullah Khan, Khawaja Muhammad Inam Pal

Section of General Surgery

Objective: To retrospectively review our experience of CT scan in cases with a final diagnosis of surgically confirmed mechanical bowel obstruction.
Methods: It is a retrospective analytical study, done from 2003 to 2008. All adult patients having undergone laparotomy in addition to a preoperative abdominal CT scan over a 5 year period were identified through the medical records and their case notes reviewed. Taking surgery to be the gold standard for diagnosing mechanical bowel obstruction, we compared results of the CT with operative findings to determine the sensitivity, specificity, positive and negative predictive values of CT scans. The data was …

Hiv And Concurrent Sexual Partnerships: Modelling The Role Of Coital Dilution, Larry Sawers, Alan G. Isaac, Eileen Stillwaggon

Economics Faculty Publications

Background: The concurrency hypothesis asserts that high prevalence of overlapping sexual partnerships explains extraordinarily high HIV levels in sub-Saharan Africa. Earlier simulation models show that the network effect of concurrency can increase HIV incidence, but those models do not account for the coital dilution effect (nonprimary partnerships have lower coital frequency than primary partnerships).

Methods: We modify the model of Eaton et al (AIDS and Behavior, September 2010) to incorporate coital dilution by assigning lower coital frequencies to non-primary partnerships. We parameterize coital dilution based on the empirical work of Morris et al (PLoS ONE, December …

Evaluation Of The Global Association Between Cholesterol-Associated Polymorphisms And Alzheimer's Disease Suggests A Role For Rs3846662 And Hmgcr Splicing In Disease Risk, Christopher R. Simmons, Fanggeng Zou, Steven G Younkin, Steven Estus

Sanders-Brown Center on Aging Faculty Publications

BACKGROUND: Recent genome-wide association studies (GWAS) have identified single nucleotide polymorphisms (SNP)s that are essentially unequivocally associated with peripheral cholesterol. Since the alleles of the APOE gene, which modulate peripheral cholesterol metabolism, and midlife plasma cholesterol are both associated with Alzheimer's disease (AD) risk, we have evaluated the hypothesis that SNPs associated with plasma cholesterol are also associated with AD.

RESULTS: Seventeen non-APOE SNPs reproducibly associated with cholesterol per GWAS were tested for association with AD in ~2,000 AD and ~4,000 non-AD subjects. As a group, these SNPs are associated with AD. Two SNPs in particular, rs3846662 and rs1532085, are …

The Use Of Light In The Treatment Of Depression, Mark D. Miller, Md

Jefferson Journal of Psychiatry

INTRODUCTION

Light has recently been reported to be a useful treatment in affective illness (1,2, 3, 4, 5, 6). What type of patients respond to this type of treatment ? What is the theoretical mechanism of action of light therapy and what are the implications of this research for the existing theories of affective illness? This review will seek answers to these questions by summarizing the recently reported studies of the effects of light on depression , by reviewing the pertinent contributions from neuroanatomy, endocrinology and circadian rhythm physiology, and, finally, by suggesting some points of integration of these recent …

Problems With Separation In An Identical Twin, Henry A. Doenlen, Md

Jefferson Journal of Psychiatry

Introduction

During residency we learn to apply the theories of development to understand and help our patients. These theories are based upon the relationship between a single childand his parents as he struggles to separate and individuate. Identical twins have special problems in that not only do they have to separate from their parents, but also from each other.

On The Outskirts Of Babel, John Matt Dorn, Md

Jefferson Journal of Psychiatry

INTRODUCTION

I admit to a fondness for book lists that began on Wednesdays in the eighth grade, when feet perched imperiously on the table in the corner I would review with inordinate glee the list of recommended reading. What seemed to others an onerous and pedantic exercise was to me a treasure map that dissolved the walls of the school around me.

The Evaluation And Treatment Of A Patient With Anorexia Nervosa, Gail S. Greenspan, Md

Jefferson Journal of Psychiatry

Introduction

Anorexia nervosa is a serious illness that has generated enormous public interest during recent times. Within the psychiatric field, numerous articles and books have been written about this syndrome. This literature reflects varied theoretical frameworks, from primarily biological approaches to family systems to psychodynamic theory. In this paper I will attempt to integrate family systems and psychodynamic theory in an understanding of a young woman with anorexia nervosa who was treated in a hospital setting.

Tlr4 Mutation Reduces Microglial Activation, Increases Aβ Deposits And Exacerbates Cognitive Deficits In A Mouse Model Of Alzheimer's Disease, Min Song, Jingji Jin, Jinghong Kou, Abhinandan Pattanayak, Jamaal Rehman, Hong-Duck Kim, Ken-Ichiro Fukuchi

NYMC Faculty Publications

BACKGROUND: Amyloid plaques, a pathological hallmark of Alzheimer's disease (AD), are accompanied by activated microglia. The role of activated microglia in the pathogenesis of AD remains controversial: either clearing Aβ deposits by phagocytosis or releasing proinflammatory cytokines and cytotoxic substances. Microglia can be activated via toll-like receptors (TLRs), a class of pattern-recognition receptors in the innate immune system. We previously demonstrated that an AD mouse model homozygous for a loss-of-function mutation of TLR4 had increases in Aβ deposits and buffer-soluble Aβ in the brain as compared with a TLR4 wild-type AD mouse model at 14-16 months of age. However, it …

Treatment Of Cerebrospinal Fluid Leak During Spinal Cord Stimulator Implantation With Epidural Blood Patches, Farid Kia, Md, Linqiu Zhou, Md, Jason Berk, Md

Department of Rehabilitation Medicine Faculty Papers

Conclusion:

Our data is consistent with prior studies in demonstrating that the incidence of dural puncture and CSF leak with SCS procedures is rare. Based on our experiences, performing an epidural blood patch intra-operatively on the contra-lateral side under fluoroscopy could prevent PDPH. This treatment should especially be considered in patients undergoing SCS trials in order to accurately assess the level of pain reduction. Patients with prior spine surgeries might pose higher risks for dural puncture and more extensive pre-operative assessment could be beneficial.

Urinary Nitrate Might Be An Early Biomarker For Pediatric Acute Kidney Injury In The Emergency Department, Asad Mian, Yue Du, Harsha K Garg, Chantal Caviness, Stuart L Goldstein, Nathan S Bryan

Department of Emergency Medicine

NO is involved in normal kidney function and perturbed in acute kidney injury (AKI). We hypothesized that urinary concentration of NO metabolites, nitrite, and nitrate would be lower in children with early AKI presenting to the emergency department (ED), when serum creatinine (SCr) was uninformative. Patients up to 19 y were recruited if they had a urinalysis and SCr obtained for routine care. Primary outcome, AKI, was defined by pediatric Risk, Injury, Failure, Loss of function, End-stage renal disease (pRIFLE) criteria. Urinary nitrite and nitrate were determined by HPLC. A total of 252 patients were enrolled, the majority (93%) of …

Brain Activation And Connectivity In Non-Disabled Multiple Sclerosis Patients, Rene A. Colorado

Dissertations and Theses (Open Access)

Multiple sclerosis (MS) is the most common demyelinating disease affecting the central nervous system. There is no cure for MS and current therapies have limited efficacy. While the majority of individuals with MS develop significant clinical disability, a subset experiences a disease course with minimal impairment even in the presence of significant apparent tissue damage on magnetic resonance imaging (MRI). The current studies combined functional MRI and diffusion tensor imaging (DTI) to elucidate brain mechanisms associated with lack of clinical disability in patients with MS. Recent evidence has implicated cortical reorganization as a mechanism to limit the clinical manifestation of …

Sub Total Aortic Replacement Using Simultaneous Bentall And Elephant Trunk Procedure, Mehreen Kisat, Umer Darr

Section of Cardiothoracic Surgery

A 22 year old female with valvular heart disease, moderate mitral valve insufficiency, moderate aortic insufficiency, extensive aneurysmal dilatation of the entire ascending aorta and arch, and segmental dilatation of descending aorta underwent entire anterior aortic replacement. We performed aortic root and valve replacement with a composite graft, followed by coronary artery reimplantation using the Bentall and De Bono technique. Simultaneously, we carried out a graft replacement of the transverse arch and descending aortic aneurysms with a woven Dacron graft using the Elephant Trunk technique. The goal of this surgery was to correct or optimally treat the multiple sites of …

Surgical Correction Of Aorto-Pulmonary Window: A Rare And Lethal Cause Of Pulmonary Hypertension, Adeel Ahmed Shamim, Mubashir Zareen Khan, Mehnaz Ahmed Atiq, Mansoor Ahmed Khan, Muhammad Muneer Amanullah

Section of Cardiothoracic Surgery

Aorto-pulmonary window is a relatively rare congenital cardiac malformation with an overall incidence of 0.1%. Pulmonary hypertension develops quickly if the lesion is left untreated hence early surgical intervention is warranted after diagnosis. The surgery for correction of APW has evolved over years, currently an open repair on cardiopulmonary bypass (CPB) with a single patch technique yields good results. Mortality is affected by association of pulmonary hypertension and other cardiac malformations. We present a case of an infant with a large type II APW with a relatively low pulmonary vascular resistance. Hospital stay was complicated because of pulmonary arterial disease …

In-Vivo Ct Dosimetry During Virtual Colonoscopy, Jonathon W. Mueller

Dissertations and Theses (Open Access)

Virtual colonoscopy (VC) is a minimally invasive means for identifying colorectal polyps and colorectal lesions by insufflating a patient’s bowel, applying contrast agent via rectal catheter, and performing multi-detector computed tomography (MDCT) scans. The technique is recommended for colonic health screening by the American Cancer Society but not funded by the Centers for Medicare and Medicaid Services (CMS) partially because of potential risks from radiation exposure. To date, no in‐vivo organ dose measurements have been performed for MDCT scans; thus, the accuracy of any current dose estimates is currently unknown.

In this study, two TLDs were affixed to the inner …

Clinical Impact Of Couch To P And Rails On Imrt And Arc Therapy, Kiley B. Pulliam

Dissertations and Theses (Open Access)

Purpose: To evaluate the clinical impact of the Varian Exact Couch on dose and volume coverage to targets and critical structures and tumor control probability (TCP) for 6-MV IMRT and Arc Therapy.

Methods: Five clinical prostate patients were planned with both, 6-MV 8-field IMRT and 6-MV 2-field RapidArc using the Eclipse treatment planning system (TPS). These plans neglected treatment couch attenuation, as is standard clinical practice. Dose distributions were then recalculated in Eclipse with the inclusion of the Varian Exact Couch (imaging couch top) and the rails in varying configurations. The changes in dose and coverage were evaluated using the …

The Development And Implementation Of An Anthropomorphic Head Phantom For The Assessment Of Proton Therapy Treatment Procedures, Paige A. Summers

Dissertations and Theses (Open Access)

Proton therapy has become an increasingly more common method of radiation therapy, with the dose sparing to distal tissue making it an appealing option, particularly for treatment of brain tumors. This study sought to develop a head phantom for the Radiological Physics Center (RPC), the first to be used for credentialing of institutions wishing to participate in clinical trials involving brain tumor treatment of proton therapy. It was hypothesized that a head phantom could be created for the evaluation of proton therapy treatment procedures (treatment simulation, planning, and delivery) to assure agreement between the measured dose and calculated dose within …

Tp53 As A Biomarker In Head And Neck Squamous Cell Carcinoma, Thomas J. Ow Md

Dissertations and Theses (Open Access)

Currently, there are no molecular biomarkers that guide treatment decisions for patients with head and neck squamous cell carcinoma (HNSCC). Several retrospective studies have evaluated TP53 in HNSCC, and results have suggested that specific mutations are associated with poor outcome. However, there exists heterogeneity among these studies in the site and stage of disease of the patients reviewed, the treatments rendered, and methods of evaluating TP53 mutation. Thus, it remains unclear as to which patients and in which clinical settings TP53 mutation is most useful in predicting treatment failure.

In the current study, we reviewed the records of a cohort …

Classification And Treatment Of Proximal Humerus Fractures: Inter-Observer Reliability And Agreement Across Imaging Modalities And Experience., Abtin Foroohar, Rick Tosti, John M Richmond, John P Gaughan, Asif M Ilyas

Rothman Institute Papers

SUMMARY: Proximal humerus fractures (PHF) are common injuries, but previous studies have documented poor inter-observer reliability in fracture classification. This disparity has been attributed to multiple variables including poor imaging studies and inadequate surgeon experience. The purpose of this study is to evaluate whether inter-observer agreement can be improved with the application of multiple imaging modalities including X-ray, CT, and 3D CT reconstructions, stratified by physician experience, for both classification and treatment of PHFs.

METHODS: Inter-observer agreement was measured for classification and treatment of PHFs. A total of sixteen fractures were imaged by plain X-ray (scapular AP and lateral), CT …

Misuses Of Computers By Adolescents, Henry A. Doenlen, M.D.

Jefferson Journal of Psychiatry

One subject that has been a topic of much recent publicity and concern has been that of computer misuse. Teenage computer programmers gaining entry into the systems of universities, hospitals and businesses have caused the most concern . The duplication of copyrighted programs and information has also been reported to cause loss of considerable money. There seems to be a subpopulation of people who spend considerable time working with computers. These individuals may do so to the exclusion of other aspects of life such as human interaction . This paper will present both my observations of this behavior and my …
