Department of Orthopaedic Surgery Faculty Papers

Developmental dysplasia of the hip (DDH) is a disabling condition of the hip that, depending on geography, can afflict between 20-80% of patients with end-stage arthritis of the hip. Despite its prevalence, the etiology of this disease remains unknown. DDH is a complex disorder with both environmental and genetic causes.. Based on the literature, the candidate genes for the disease are HOXB9, collagen type I α1, and DLX 3. The purpose of our study was to map and characterize the gene or genes responsible for this disorder by family linkage analysis. We recruited one 18-member, multigeneration affected family to provide …


Therapeutic Strategies Aimed To Facilitate Axonal Regeneration And Functional Recovery Following Traumatic Spinal Cord Injury, Woon Chow Sep 2009

Therapeutic Strategies Aimed To Facilitate Axonal Regeneration And Functional Recovery Following Traumatic Spinal Cord Injury, Woon Chow

Theses and Dissertations

Traumatic spinal cord injury (SCI) is a physically debilitating, emotionally devastating, financially costly, and life-changing condition that afflicts more than 1,000,000 people in the United States alone. Owing to the characteristic neuropathology and low regenerative capacity of the central nervous system, many victims of SCI are left permanently paralyzed. Though the tissue damage caused by the initial insult almost certainly cannot be reversed, intensive research in recent years to elucidate the cellular and molecular events that follows has provided new grounds for optimism. Accordingly, in this dissertation, we present a number of potential treatment strategies aimed to address some of …

Progress Toward The Synthesis Of A Truncated Ergoline, Ryan D. Enck, Matthew Hart

Student Summer Scholars Manuscripts

Many people are diagnosed with thyroid related disorders, and many more are unaware of their existing thyroid problems. T1AM, a naturally occurring metabolite of the thyroid hormone (TH), has been shown to activate the Trace Amine Associated Receptor 1 (TAAR1) and exhibits effects that oppose those of the TH. It is, therefore, likely that there is regulatory relationship between T1AM and the TH. In order to better understand this relationship, a compound must be developed that will effectively block TAAR1. Previously our lab has examined the two different mirror images of apomorphine. One of the mirror images inhibited and the …


Estimating Effects By Combining Instrumental Variables With Case-Control Designs: The Role Of Principal Stratification, Russell T. Shinohara, Constantine E. Frangakis, Elizabeth Platz, Konstantinos Tsilidis Sep 2009

Estimating Effects By Combining Instrumental Variables With Case-Control Designs: The Role Of Principal Stratification, Russell T. Shinohara, Constantine E. Frangakis, Elizabeth Platz, Konstantinos Tsilidis

Johns Hopkins University, Dept. of Biostatistics Working Papers

The instrumental variable framework is commonly used in the estimation of causal effects from cohort samples. In the case of more efficient designs such as the case-control study, however, the combination of the instrumental variable and complex sampling designs requires new methodological consideration. As the prevalence of Mendelian randomization studies is increasing and the cost of genotyping and expression data can be high, the analysis of data gathered from more cost-effective sampling designs is of prime interest. We show that the standard instrumental variable analysis is not applicable to the case-control design and can lead to erroneous estimation and inference. …

Department of Surgery Docs

Adrenal cysts are rare clinical entities that can present as acute abdomen through rupture and internal hemorrhage as well as chronic symptoms such as gastrointestinal disturbances. A 20-year-old girl presented to our hospital with a 4-years history of abdominal pain and diarrhea. Ultrasound of the abdomen revealed a cystic area measuring 10 x 10 cm between the spleen and left kidney. Computed tomography scan showed a large cystic, homogeneous mass measuring 12.8 x 9.5 x 9.4 cm in the left hypochondrium with most likely origin from the left adrenal gland. Limited work up for hormone hypersecretion was negative. The Patient …


Designing A Simulation For Student Evaluation Using Scriven's Key Evaluation Checklist, Shelly Jensen Reed Sep 2009

Designing A Simulation For Student Evaluation Using Scriven's Key Evaluation Checklist, Shelly Jensen Reed

Faculty Publications

Human patient simulation use has increased dramatically in nursing education over the past 10 years, with many benefits. One advantage is that it allows students to learn by practicing skills in a risk-free environment, with immediate faculty feedback. Another benefit is that it prepares and ensures the competence of student nurses, leading to improved patient safety outcomes. Student opinions gathered in a survey of nursing schools and simulator centers favored use of competency evaluation using simulation in at least some circumstances. As little research concerning use of simulation to evaluate student competency can be found, an established guide such as …

Faculty and Staff Scholarship

Objective: To determine whether minimal snoring is benign in children. Procedure: 22 rarely snoring children (mean age = 6.9 years, 11 females) and age- and sex-matched controls participated in an auditory oddball task wearing 128-electrode nets. Parents completed the Conners Parent Rating Scales–Revised Long (CPRS–R:L). Results: Snorers scored significantly higher on four CPRS-R:L subscales. Stepwise regression indicated that two ERP variables from a region of the ERP that peaked at 844 msec post-stimulus onset predicted CPRS-R:L Attention Deficit Hyperactivity Disorder (ADHD) Index scores. Conclusions: Occasional snorers, according to parental report, do exhibit ADHD-like behaviors. Basic sensory processing is longer than …

Revitalisation, Rigour And Relevance: The Citizen-Client And Planning In The Health Services., Vivienne Byers Sep 2009

Revitalisation, Rigour And Relevance: The Citizen-Client And Planning In The Health Services., Vivienne Byers

Conference Papers

Whereas, in many OECD countries strategic planning in health care has been in evidence since the 1970s, in Ireland the emergence of strategic management processes in health care planning didn’t occur until the 1990s.

This paper reports on part of a comparative study of health services planning in Ireland and in Canada. How can the strategic management of the Irish health services in the form of service planning be implemented? The focus of this paper is the identification of two key stumbling blocks to success in this endeavour. These include the limitations of the control mechanism, the legislation, underpinning service …


Strategic Change In The Irish Health Services: Comparative Case Studies In Planning, Vivienne Byers Sep 2009

Strategic Change In The Irish Health Services: Comparative Case Studies In Planning, Vivienne Byers

Conference Papers

This paper reports on a study of the implementation of service planning in the Irish health services in the context of significant organisational change. One of the central mechanisms of the Strategic Management Initiative (SMI) is the devolution of accountability and responsibility from the centre to executive agencies. Service planning in the Irish health care sector is seen as part of this strategic planning ethos.

This study in examining the function and implementation of the service plan in the Irish health care system drew comparisons with the Canadian experience. A multiple case study design was utilised. Key research questions were …


Broad Range Amino Acid Specificity Of Rna-Dependent Lipid Remodelling By Multiple Peptide Resistance Factors, Hervé Roy, Michael Ibba Sep 2009

Broad Range Amino Acid Specificity Of Rna-Dependent Lipid Remodelling By Multiple Peptide Resistance Factors, Hervé Roy, Michael Ibba

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Aminoacylphosphatidylglycerol synthases (aaPGSs) are multiple peptide resistance factors that transfer amino acids from aminoacyl-tRNAs to phosphatidylglycerol (PG) in the cytoplasmic membrane. Aminoacylation of PG is used by bacteria to decrease the net negative charge of the cell envelope, diminishing affinity for charged molecules and allowing for adaptation to environmental changes. Lys-PGS, which transfers lysine to PG, is essential for the virulence of certain pathogens, providing resistance to both host cationic antimicrobial peptides and therapeutic antibiotics. Ala-PGS was also recently described, but little is known about the possible activities of other members of the highly diverse aaPGS family of proteins. Systematic …

Geographic Variation And Environmental Conditions As Cofactors In Chlamydia Psittaci Association With Ocular Adnexal Lymphomas: A Comparison Between Italian And African Samples, Alessandro Carugi, Anna Onnis, Giuseppina Antonicelli, Benedetta Rossi, Susanna Mannucci, Anna Luzzi, Stefano Lazzi, Cristiana Cristiana Bellan, Gian Marco Tosi, Shahin Sayed, Giulia De Falco, Lorenzo Leoncini

Pathology, East Africa

A particular extra-nodal lymphoma type arises from B cells of the marginal zone (MZ) of mucosa-associated lymphoid tissue (MALT). The aetiology ofMZ lymphomas suggests that they are associated with chronic antigenic stimulation by microbial pathogens, among which Helicobacter pylori-associated gastricMALT lymphoma is the best studied. Recently, MALT lymphomas have been described in the context of chronic conjunctivitis, which can be associated with Chlamydia spp. infection. Studies from Italy showed the presence of Chlamydia psittaci in 87% of ocular adnexal lymphomas (OAL), and C. psittaci has been described in a large part of samples from Austria and Korea as well. However, …


Adapting To Dynamic Stimulus-Response Values: Differential Contributions Of Inferior Frontal, Dorsomedial, And Dorsolateral Regions Of Prefrontal Cortex To Decision Making., Derek G V Mitchell, Qian Luo, Shelley B Avny, Tomasz Kasprzycki, Karanvir Gupta, Gang Chen, Elizabeth C Finger, R James R Blair Sep 2009

Adapting To Dynamic Stimulus-Response Values: Differential Contributions Of Inferior Frontal, Dorsomedial, And Dorsolateral Regions Of Prefrontal Cortex To Decision Making., Derek G V Mitchell, Qian Luo, Shelley B Avny, Tomasz Kasprzycki, Karanvir Gupta, Gang Chen, Elizabeth C Finger, R James R Blair

Brain and Mind Institute Researchers' Publications

Dorsomedial prefrontal cortex (dmPFC), dorsolateral prefrontal cortex (dlPFC), and inferior frontal gyrus (IFG) have all been implicated in resolving decision conflict whether this conflict is generated by having to select between responses of similar value or by making selections following a reversal in reinforcement contingencies. However, work distinguishing their individual functional contributions remains preliminary. We used functional magnetic resonance imaging to delineate the functional role of these systems with regard to both forms of decision conflict. Within dmPFC and dlPFC, blood oxygen level-dependent responses increased in response to decision conflict regardless of whether the conflict occurred in the context of …

Measuring Illness Uncertainty In Men Undergoing Active Surveillance (As) For Prostate Cancer, Peter C. Albertsen Sep 2009

Measuring Illness Uncertainty In Men Undergoing Active Surveillance (As) For Prostate Cancer, Peter C. Albertsen

Articles - Patient Care

Uncertainty is an aversive experience and plays an important role in the lives of men undergoing active surveillance (AS) (earlier referred to as watchful waiting) for early-stage prostate cancer. Yet reliable and valid measures of uncertainty have not been fully tested in this population. This secondary analysis therefore tested the reliability of the Mishel Uncertainty in Illness Scale – Community Form (MUIS-C; Mishel, 1997b) for use with a population of men undergoing AS for prostate cancer.


New Tfii-I Family Target Genes Involved In Embryonic Development, Aleksandr V. Makeyev, Dashzeveg Bayarsaihan Sep 2009

New Tfii-I Family Target Genes Involved In Embryonic Development, Aleksandr V. Makeyev, Dashzeveg Bayarsaihan

SoDM Articles

Two members of the TFII-I family transcription factor genes, GTF2I and GTF2IRD1, are the prime candidates responsible for the craniofacial and cognitive abnormalities of Williams syndrome patients. We have previously generated mouse lines with targeted disruption of Gtf2ird1 and Gtf2i. Microarray analysis revealed significant changes in the expression profile of mutant embryos. Here we described three unknown genes that were dramatically down-regulated in mutants. The 2410018M08Rik/Scand3 gene encodes a protein of unknown function with CHCH and hATC domains. Scand3 is downregulated during mouse embryonic stem cell (ES) differentiation. 4933436H12Rik is a testis-specific gene, which encodes a protein with no known …
