Operative Treatment Of Bilateral Hip Dislocation In Children With Arthrogryposis Multiplex Congenita, S Asif, Masood Umer, Rashid Baig

Department of Surgery Docs

Abstract

PURPOSE:

Arthrogryposis multiplex congenita (AMC) is a rare syndrome with multiple joint contractures. It is commonly believed that bilaterally dislocated hips associated with joint contractures should not be reduced, because movement is satisfactory, while open reduction leads to poor results. This report presents our experience with surgical management of bilateral dislocation of hips in children with AMC.

METHODS:

During the period 1990 to 2000, we performed open reduction on 8 hips of 4 children with AMC. The mean age at surgery was 23 months (range, 5-48 months). Open reduction and capsular plication without any bony procedure were performed in …

Binary Isotonic Regression Procedures, With Application To Cancer Biomarkers, Debashis Ghosh, Moulinath Banerjee, Pinaki Biswas

The University of Michigan Department of Biostatistics Working Paper Series

There is a lot of interest in the development and characterization of new biomarkers for screening large populations for disease. In much of the literature on diagnostic testing, increased levels of a biomarker correlate with increased disease risk. However, parametric forms are typically used to associate these quantities. In this article, we specify a monotonic relationship between biomarker levels with disease risk. This leads to consideration of a nonparametric regression model for a single biomarker. Estimation results using isotonic regression-type estimators and asymptotic results are given. We also discuss confidence set estimation in this setting and propose three procedures for …

Semiparametic Models And Estimation Procedures For Binormal Roc Curves With Multiple Biomarkers, Debashis Ghosh

The University of Michigan Department of Biostatistics Working Paper Series

In diagnostic medicine, there is great interest in developing strategies for combining biomarkers in order to optimize classification accuracy. A popular model that has been used for receiver operating characteristic (ROC) curve modelling when one biomarker is available is the binormal model. Extension of the model to accommodate multiple biomarkers has not been considered in this literature. Here, we consider a multivariate binormal framework for combining biomarkers using copula functions that leads to a natural multivariate extension of the binormal model. Estimation in this model will be done using rank-based procedures. We show that the Van der Waerden rank score …

Methods To Impair Hematologic Cancer Progenitor Cells And Compounds Related Thereto, Craig Jordan

Internal Medicine Faculty Patents

Primitive or progenitor hematologic cancer cells have been implicated in the early stages and development of leukemia and malignant lymphoproliferative disorders, including acute myelogenous leukemia (AML), chronic myelogenous leukemia (CML) and chronic lymphoid leukemia (CLL). Interleukin-3 receptor alpha chain (IL-3Rα or CD123) is strongly expressed on progenitor hematologic cancer cells, but is virtually undetectable on normal bone marrow cells. The present invention provides methods of impairing progenitor hematologic cancer (e.g., leukemia and lymphomic) cells by selectively targeting cells expressing CD123. These methods are useful in the detection and treatment of leukemias and malignant lymphoproliferative disorders. Also provided are compounds useful …

The Cell Surface Receptor Slam Controls T Cell And Macrophage Functions, Ninghai Wang, Abhay Satoskar, William Faubion, Susumu Okamoto, Stefan Feske, Charles A. Gullo Phd, Kareem Clarke, Miriam Rodriguez Sosa, Arlene H. Sharpe, Cox Terhorst

Biochemistry and Microbiology

Signaling lymphocyte activation molecule (SLAM), a glycoprotein expressed on activated lymphocytes and antigen-presenting cells, has been shown to be a coregulator of antigen-driven T cell responses and is one of the two receptors for measles virus. Here we show that T cell receptor–induced interleukin (IL)-4 secretion by SLAM−/− CD4+ cells is down-regulated, whereas interferon γ production by CD4+ T cells is only slightly up-regulated. Although SLAM controls production of IL-12, tumor necrosis factor, and nitric oxide in response to lipopolysaccharide (LPS) by macrophages, SLAM does not regulate phagocytosis and responses to peptidoglycan or CpG. Thus, SLAM acts as a coreceptor …

Diversion Of The Inferior Vena Cava Following Repair Of Atrial Septal Defect Causing Hypoxemia, Ellen A. Thompson, Silvestre Cansino, Dennis Moritz, Romaine Perdue Perdue

Internal Medicine

Atrial septal defects (ASDs) are a common congenital abnormality, and operative repair is a routine, safe procedure. Diversion of the inferior vena cava (IVC) into the left atrium is an unusual complication following ASD closure. We report a case that illustrates the problem created by this right-to-left shunt. A middle-aged woman underwent ASD repair. She developed hypoxemia postoperatively. A transthoracic echocardiogram confirmed a right-to-left shunt, found only with agitated saline injected into the femoral vein, not into the basilic vein. Surgical reexploration revealed a residual ASD diverting IVC flow into the left atrium, which was repaired with a pericardial patch. …

Deletion Of The Na/K-Atpase Alpha1-Subunit Gene (Atp1a1) Does Not Prevent Cavitation Of The Preimplantation Mouse Embryo., L C Barcroft, A E Moseley, J B Lingrel, A J Watson

Obstetrics & Gynaecology Publications

Increases in Na/K-ATPase activity occur concurrently with the onset of cavitation and are associated with increases in Na(+)-pump subunit mRNA and protein expression. We have hypothesized that the alpha1-isozyme of the Na/K-ATPase is required to mediate blastocyst formation. We have tested this hypothesis by characterizing preimplantation development in mice with a targeted disruption of the Na/K-ATPase alpha1-subunit (Atp1a1) using embryos acquired from matings between Atp1a1 heterozygous mice. Mouse embryos homozygous for a null mutation in the Na/K-ATPase alpha1-subunit gene are able to undergo compaction and cavitation. These findings demonstrate that trophectoderm transport mechanisms are maintained in the absence of the …

Differences In Peripheral Noradrenergic Function Among Actively Drinking And Abstinent Alcohol-Dependent Individuals., Ashwin A. Patkar, Charles A. Marsden, Prakash C. Naik, David A. Kendall, Raman Gopalakrishnan, Michael J. Vergare, Stephen P. Weinstein

Department of Psychiatry and Human Behavior Faculty Papers

We examined whether excessive alcohol consumption was related to changes in plasma levels of noradrenaline (NA) and whether these changes recover following abstinence. We also explored whether there were differences in NA levels between Type I and Type II alcoholics and controls during active drinking and abstinence. Plasma concentrations of NA were determined in (1) 27 Caucasian men with alcohol dependence who were regularly drinking (active drinkers) within 24 hours of hospitalization, (2) 29 Caucasian alcohol-dependent men who were in remission (abstinent for a minimum of three months), and (3) 28 race- and gender-matched healthy controls. NA concentrations were significantly …

Art Therapy As A Measure Of Children’S Concept Of Surgery: A Preliminary Study, Emily C. Clark

EVMS School of Health Professions Theses & Dissertations

Surgery is a strange, and often frightening experience for children. A number of programs have been studied which attempt to prepare children for the surgery experience. Art therapy may be especially suited to help prepare children for surgery because art making is an effective form of communication for children, and can allow them to express their thoughts and fears about surgery. Unfortunately, studies of art therapy preparation programs are rare, and usually take the form of case studies. This research study is the first step in designing an art therapy preparation program for preparing children for surgery.

Age-Related Hearing Loss And Its Association With Reactive Oxygen Species And Mitochondrial Dna Damage, Michael D. Seidman, Nadir Ahmad, Dipa Joshi, Jake Seidman, Sujatha Thawani, Wayne S. Quirk

All Faculty Scholarship for the College of the Sciences

Age-related hearing loss, known as presbyacusis, is characterized by the progressive deterioration of auditory sensitivity associated with the aging process and is the leading cause of adult auditory deficiency in the USA. Presbyacusis is described as a progressive, bilateral, high-frequency hearing loss that is manifested on audiometric assessment by a moderately sloping pure tone audiogram. Approximately 23% of the population between 65 and 75 years of age, and 40% of the population older than 75 years of age are affected by this condition. It was estimated in 1980 that 11% of the population was 76 years or older and this …

Neurology In The 21st Century: Contemporary State Of Diagnostics And Therapeutics, Saad Shafqat, Mohammad Wasay

Department of Medicine

Although neurological disease has been recognized since antiquity, neurology as a systematic clinical discipline is less than 130 years old. Neurological practice has traditionally been constrained by the complexity of the human nervous system, which has been slow to yield its secrets. Over the last three decades, however, clinical neurology has been transformed in terms of both diagnostics and therapeutics and now marches in lockstep with the cutting edge of medicine. Efficacious treatments are now available for the majority of neurological diseases, including epilepsy, migraine, Guillain-Barre syndrome, Parkinson's disease, multiple sclerosis, and ischemic stroke. This neurological revolution has been enabled …

Unilateral Olfactory Thresholds In A Chemosensory Clinic Population, Beverly Cowart, Edmund Pribitkin, David Rosen, Christopher Klock, Timothy Laflam

Department of Otolaryngology - Head and Neck Surgery Faculty Papers

Poster presentation at 26th Annual Meeting of the Association of Chemoreception Sciences in Sarasota Florida, April 21-25, 2004.

INTRODUCTION

Because there is the possibility of unilateral loss of olfactory function or differential degrees of olfactory dysfunction in the two nostrils, unilateral tests of olfactory threshold sensitivity are routinely included in many chemosensory clinical test batteries to supplement bilateral tests (e.g., Cain et al., 1988; Hummel et al., 1997). Surprisingly, however, the results of unilateral testing in patients with chemosensory complaints have not been extensively reported. Thus, it is unclear how useful these additional measures are in characterizing individual patients.

Evaluating Markers For Selecting A Patient's Treatment, Xiao Song, Margaret S. Pepe

UW Biostatistics Working Paper Series

Selecting the best treatment for a patient's disease may be facilitated by evaluating clinical characteristics or biomarker measurements at diagnosis. We consider how to evaluate the potential of such measurements to impact on treatment selection algorithms. For example, magnetic resonance neurographic imaging is potentially useful for deciding whether a patient should be treated surgically for carpal tunnel syndrome or if he/she should receive less invasive conservative therapy. We propose a graphical display, the selection impact (SI) curve, that shows the population response rate as a function of treatment selection criteria based on the marker. The curve can be useful for …
