Heterotopic Ossification: Cellular Basis, Symptoms, And Treatment, Brian Wolfe

Senior Honors Theses

Heterotopic ossification (HO) is the process by which calcified bone develops in soft tissues. Because of the abnormal calcification, complications such as bone deformation, loss of range of motion, and joint immobility adversely affect patients. There are many genetic types of heterotopic ossification, namely fibrodysplasia ossificans progressiva, progressive osseous heteroplasia, and Albright hereditary osteodystrophy. However, this condition can also arise from surgery, burns, or traumatic injuries, so it is seen as an important area for research in the future. There are various treatments available such as non-steroidal anti-inflammatory drugs and radiation therapy, as well as combinations of the two. The …

Decorin Expression, Straw-Like Structure, And Differentiation Of Human Costal Cartilage, Michael W. Stacey, Janna Grubb, Anthony Asmar, Julie Pryor, Hani Elsayed-Ali, Ali Beskok, Diganta Dutta, Annie Fecteau, Alice Werner, Dennis A. Darby, Robert Kelly

Bioelectrics Publications

Costal cartilage is much understudied compared with the load-bearing cartilages. Abnormally grown costal cartilages are associated with the inherited chest wall deformities pectus excavatum and pectus carinatum resulting in sunken and pigeon chests, respectively. A lack of understanding of the ultrastructural and molecular biology of costal cartilage is a major confounder in predicting causes and outcomes of these disorders. This study analyzed the structure of marginal human costal cartilage (ribs 6-10) through scanning electron and atomic force microscopes and identified the presence of straw-like structures running longitudinally. We also demonstrated that chondrocytes tend to occur singly or as doublets and …

Is Radial Extracorporeal Shock Wave Therapy An Effective Treatment For Chronic Plantar Fasciitis In Adults?, Lauren H. Rucker

PCOM Physician Assistant Studies Student Scholarship

OBJECTIVE: The objective of this selective EBM review is to determine whether or not radial extracorporeal shock wave therapy (ESWT) is an effective treatment in adults with chronic plantar fasciitis.

STUDY DESIGN: Review of three English language primary studies published between 2008 and 2010.

DATA SOURCES: Two randomized control trials and one cohort study analyzing the effects of radial extracorporeal shock wave therapy on chronic plantar fasciitis were found using the OVID, Medline and Cochrane Databases.

OUTCOMES MEASURED: Each of the three studies measured improvement in pain from baseline after patients were treated with ESWT. Pain levels were quantified using …

Decision Quality Instrument For Treatment Of Hip And Knee Osteoarthritis: A Psychometric Evaluation, Karen R. Sepucha, Dawn Stacey, Catharine F. Clay, Yuchiao Chang

Dartmouth Scholarship

A high quality decision requires that patients who meet clinical criteria for surgery are informed about the options (including non-surgical alternatives) and receive treatments that match their goals. The aim of this study was to evaluate the psychometric properties and clinical sensibility of a patient self report instrument, to measure the quality of decisions about total joint replacement for knee or hip osteoarthritis.

Femoroacetabular Impingement: Saving The Joint, Ronald Huang, Javad Parvizi

Department of Orthopaedic Surgery Faculty Papers

Many factors have been linked to the development of osteoarthritis (OA) of the hip, but often, cases are still considered “idiopathic.” Femoroacetabular impingement (FAI) has been suggested as a possible etiologic factor for the otherwise “idiopathic” cases. It is theorized that the subtle morphologic abnormalities seen at the head-neck junction and acetabulum in FAI may lead to labral tears, chondral damage, and subsequent progression of OA. Prevalence of FAI has been suggested to be as high as 14% in the general population. It often presents in young active patients that subject their hip joint to repetitive micro trauma associated with …

Natural History Study Of Arthrogryposis Multiplex Congenita, Amyoplasia Type, Trisha Nichols

Dissertations and Theses (Open Access)

Arthrogryposis or Arthrogrypsosis Multiplex Congenita (AMC) are terms used to describe the clinical finding of multiple congenital contractures. There are more than 300 distinct disorders associated with arthrogryposis. Amyoplasia is the most common type of arthrogryposis and is often referred to as the “classic” type. There is no known cause of amyoplasia and no risk factors have been identified. Moreover, there is no established diagnostic criteria, which has led to inconsistency and confusion in the medical literature. The purpose of this study was to describe the natural history of amyoplasia, to determine if there are any identifiable risk factors and …

Effect Of Calcium Supplements On Risk Of Myocardial Infarction And Cardiovascular Events: Meta-Analysis, Mark J. Bolland, Allison Avenell, John A. Baron, A. Grey

Dartmouth Scholarship

Objective: To investigate whether calcium supplements increase the risk of cardiovascular events.

Osteoporosis is a major cause of morbidity and mortality in older people. Calcium supplements margin- ally reduce the risk of fracture, and most guidelines recommend adequate calcium intake as an integral part of the prevention or treatment of osteoporosis. Consequently, calcium supplements are commonly used by people over the age of 50. Observational stu- dies suggest that high calcium intake might protect against vascular disease, and the findings are consis- tent with those of interventional studies of calcium sup- plements thatshow improvementin some vascular risk factors. In contrast, …

Determination Of Sphk1 In The Development Of A Murine Model Of Inflammatory Arthritis, Deanna Andrea Baker

MUSC Theses and Dissertations

Patients with rheumatoid arthritis (RA) have an over production of pro-inflammatory cytokines, especially TNFα, causing joint erosions and disability in untreated patients. Targeted therapies have had some success but are not without side effects and limitations; additionally, patients become refractory to treatment, and are obligated to use a combination of therapies. Therefore, new therapeutics are necessary. One novel target is sphingolipids, specifically sphingosine kinase 1 (SphK1). Previous research has demonstrated that knockdown/knockout of SphK1 influences the production of inflammatory mediators (i.e. COX-2 and PGE2) in vitro and in vivo. Since sphingosine 1 phosphate (S1P) receptors are upregulated in RA synovium, …
