Mechanical Properties Of Canine Patella-Ligament-Tibia Segment., Jeffery Biskup, Andy Freeman, W Camisa, J Innes, Michael Conzemius

Jeffery Biskup, DVM, DACVS

OBJECTIVE: To test the ex vivo mechanical properties of canine patella-ligament-tibia (PLT) segment and establish the relationship between donor size and PLT dimensions to the mechanical properties of PLT grafts.STUDY DESIGN: Ex vivo mechanical testing study. SAMPLE POPULATION: Canine PLT segments (n = 21 dogs; 42 PLT). METHODS:Morphometric measurements of PLT segments were taken from computed tomography (CT) images and compared with results obtained using calipers. PLT were tested to failure at a rate of 100% length/s. Mechanical properties and failure mode were recorded. RESULTS: PLT width and thickness (P < .001 for both) measured by calipers were significantly lower than those taken from CT images. Thirty-five (83%) specimens failed by avulsion fracture from the patella, 1 failed mid-ligament, and 6 failed by tibial fracture. Dog weight and PLT length had the strongest Pearson's r value when correlated with load at failure (r = 0.73, 0.81, respectively). CONCLUSION:Dog weight and PLT length were the best predictors of load at failure. PLT failure load of dogs weighing >25 kg were similar to those reported for ...

An Evaluation Of Complications Following Ultrasound Guided Regional Block Anesthesia In Outpatient Hand Surgery, Daniel Calem, Armen C. Voskeridjian, Md, Michael Rivlin, Md, Pedro Beredjiklian, Md, Mark L. Wang, Md, Phd

Phase 1

Introduction: The utilization of ultrasound-guided peripheral nerve blocks in orthopedic surgery has increased in popularity as the anesthesia of choice for the management of perioperative pain. Peripheral nerve blockade has been shown to increase overall surgical efficiency, improve patient satisfaction, reduce postoperative narcotic use, and decrease the duration of facility admissions, while increasing overall cost-effectiveness. To date, scant literature exists regarding the safety and efficacy of ultrasound-guided supraclavicular blocks used in common hand surgery procedures, and the rate of neurologic and vascular complications remains unknown.

Objective: The purpose of this study was to examine the effectiveness and complication rate of ...

Mohamed, Chengyuan Wu, Ashwini Sharan

Department of Neurosurgery Faculty Papers

Imaging in the field of epilepsy surgery remains an essential tool in terms of its ability to identify regions where the seizure focus might present as a resectable area. However, in many instances, an obvious structural abnormality is not visualized. This has created the opportunity for new approaches and imaging innovation in the field of epilepsy, such as with Diffusion Tensor Imaging (DTI) and Diffusion Tensor Tractography (DTT). In this study, we aim to evaluate the use of DTI and DTT as a predictive model in the field of epilepsy, specifically Temporal Lobe Epilepsy (TLE), and correlate their clinical significance ...

Department of Orthopaedic Surgery Faculty Papers

Inactive mammalian tolloid-like 1 (tll1) and mutations detected in tolloid-like 1 (TLL1) have been linked to the lack of the heart septa formation in mice and to a similar human inborn condition called atrial-septal defect 6 (ASD6; OMIM 613087, formerly ASD II). Previously, we reported four point mutations in TLL1 found in approximately 20% of ASD6 patients. Three mutations in the coding sequence were M182L, V238A, and I629V. In this work, we present the effects of these mutations on TLL1 function. Three recombinant cDNA constructs carrying the mutations and one wild-type construct were prepared and then expressed in HT-1080 cells ...

Surgical Perioperative Leadership: The Association Between Leadership Style And Team Job Satisfaction, Corey Louise Jamison Jan 2019

Surgical Perioperative Leadership: The Association Between Leadership Style And Team Job Satisfaction, Corey Louise Jamison

Walden Dissertations and Doctoral Studies

Abstract

The perioperative operating room (OR) is a highly complex, fast-paced environment where countless transactions must be executed with efficiency, speed, and accuracy, and where mistakes of any kind could lead to adverse patient outcome, injury, or death. The surgeon, as leader of the procedure and the OR team, sets the overall climate of the OR and determines how willing (or unwilling) team members are to speak up about potential errors or unsafe patient conditions. This exploration of the relationship between perioperative surgeon leadership style and OR team member job satisfaction fills a gap unaddressed in the literature using items ...

Student Papers & Posters

BACKGROUND: Liver transplantation is the best treatment for end-stage liver disease. The interruption of the blood supply to the donor liver during cold storage damages the liver, affecting how well the liver will function after transplant. The drug Simvastatin may help to protect donor livers against this damage and improve outcomes for transplant recipients. The aim of this study is to evaluate the benefits of treating the donor liver with Simvastatin compared with the standard transplant procedure.

PATIENT AND METHODS: We propose a prospective, double-blinded, randomized phase 2 study of 2 parallel groups of eligible adult patients. We will compare ...

Department of Orthopaedic Surgery Faculty Papers

There is a well-established link between cytokine expression and the progression of intervertebral disc degeneration. Among these cytokines, interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α) are the most commonly studied. To investigate whether systemic hTNF-α overexpression affects intervertebral disc health, we studied the spine phenotype of Tg197 mice, a widely used hTNF-α transgenic line. These mice were studied at 12-16 weeks of age using comprehensive histochemical and immunohistological analysis of the spinal motion segment. Micro-CT analysis was performed to quantify vertebral trabecular bone architecture. The Tg197 mice evidenced spontaneous annular tears and herniation with increased vascularity in subchondral bone and ...

Explantation Of Infected Thoracic Endovascular Aortic Repair, Emily Y. Fan, Dejah R. Judelson, Andres Schanzer

Open Access Articles

Prosthetic graft infection is a rare and serious complication of thoracic endovascular aortic repair associated with high mortality and posing unique challenges for treatment. The prosthetic graft infection is often identified late as patients present with mild nonspecific symptoms. We describe the successful medical management and surgical explantation of an infected thoracic endograft with an aorta-bronchial fistula, using an inline reconstruction with an antibiotic-soaked synthetic graft. In this report, we provide an example of a patient with an infected thoracic endograft and how inline reconstruction combined with appropriate medical management is an acceptable treatment strategy.

BACKGROUND: Junctional adhesion molecule-A (JAM-A) is an adhesion molecule whose overexpression on breast tumor tissue has been associated with aggressive cancer phenotypes, including human epidermal growth factor receptor-2 (HER2)-positive disease. Since JAM-A has been described to regulate HER2 expression in breast cancer cells, we hypothesized that JAM-dependent stabilization of HER2 could participate in resistance to HER2-targeted therapies.

METHODS: Using breast cancer cell line models resistant to anti-HER2 drugs, we investigated JAM-A expression and the effect of JAM-A silencing on biochemical/functional parameters. We also tested whether altered JAM-A expression/processing underpinned differences between drug-sensitive and -resistant cells and acted ...

Cost Effectiveness Of Bilateral Prophylactic Mastectomy With And Without Different Breast Reconstruction Techniques Versus Screening In Women With High Risk Of Breast Cancer In The Canadian Province Of Ontario, Badria Aljohani

Electronic Thesis and Dissertation Repository

We aimed to investigate the cost-effectiveness of bilateral prophylactic mastectomy (BPM) with and without different reconstruction for the purpose of determining which strategies represent value for money. We developed a decision analytic model to project the lifetime clinical and economic consequences of different strategies. The decision model was parameterized using 10-year follow up and cost data from Ontario administrative health databases and Ontario Cancer registry. Compared to the organized screening-based strategy, surgical strategies ranged from being more effective and cost-saving and up to being associated with an incremental cost effectiveness ratio (ICER) of $63,010 per quality-adjusted life year (QALY ...

Potential Role Of Csf Cytokine Profiles In Discriminating Infectious From Non-Infectious Cns Disorders., Danielle Fortuna, D. Craig Hooper, Amity L. Roberts, Larry A. Harshyne, Michelle Nagurney, Mark T. Curtis

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Current laboratory testing of cerebrospinal fluid (CSF) does not consistently discriminate between different central nervous system (CNS) disease states. Rapidly distinguishing CNS infections from other brain and spinal cord disorders that share a similar clinical presentation is critical. New approaches focusing on aspects of disease biology, such as immune response profiles that can have stimulus-specific attributes, may be helpful. We undertook this preliminary proof-of-concept study using multiplex ELISA to measure CSF cytokine levels in various CNS disorders (infections, autoimmune/demyelinating diseases, lymphomas, and gliomas) to determine the potential utility of cytokine patterns in differentiating CNS infections from other CNS diseases ...
