College of Osteopathic Medicine (TUC) Publications and Research

Study Design Prospective study.

Objective Because single-level disk arthroplasty or arthrodesis in the lower subaxial spine improves headaches after surgery, we studied whether this effect may be better appreciated after two-level arthroplasty.

Methods We performed an independent post hoc analysis of two concurrent prospective randomized investigational device exemption trials for cervical spondylosis, one for single-level treatment and the other for two adjacent-level treatments.

Results For the one-level study, baseline mean headache scores significantly improved at 60 months for both the cervical disk arthroplasty (CDA) and anterior cervical diskectomy and fusion (ACDF) groups (p < 0.0001). However, mean improvement in headache scores was not statistically different between the investigational and control groups from 6 months through 60 months. For the two-level study, baseline mean headache scores significantly improved at 60 months for both the CDA and ACDF groups (p < 0.0001). The CDA group demonstrated greater improvement from baseline at all points; this difference was statistically significant at 6, 12, 24, 36, and 48 months but not at 18 and 60 months.

Conclusion Both CDA and ACDF at either ...

Athletes and their doctors have the choice of using an allograft or autograft in reconstruction surgeries. The purpose of this study is to see if there is a difference in the healing mechanism and surgical outcome in using an allograft or autograft during orthopedic surgical procedures, as well as to analyze graft rejection and disease transmission through donor tissue.

Doctors and athletic trainers were interviewed in order to learn about the healing mechanisms and advantages and disadvantages of allografts and autografts in order to conclude if one was better than the other. College level athletes on different sports teams were ...


Gender Differences In Choice Of Procedure And Case Fatality Rate For Elderly Patients With Acute Cholecystitis: A Masters Thesis, Courtney E. Collins 2015 University of Massachusetts Medical School

Gender Differences In Choice Of Procedure And Case Fatality Rate For Elderly Patients With Acute Cholecystitis: A Masters Thesis, Courtney E. Collins

GSBS Dissertations and Theses

Background: Treatment decisions for elderly patients with gallbladder pathology are complex. Little is known about what factors go into treatment decisions in this population. We used Medicare data to examine gender-based differences in the use of cholecystectomy vs. cholecystostomy tube placement in elderly patients with acute cholecystitis.

Methods: We queried a 5% random sample of Medicare data (2009-2011) for patients >65 admitted for acute cholecystitis (by ICD-9 code) who subsequently underwent a cholecystectomy and/or cholecystostomy tube placement. Demographic information (age, race), clinical characteristics (Elixhauser index, presence of biliary pathology), and hospital outcomes (case fatality rate, length of stay, need ...

Improved Sensitivity To Fluorescence For Cancer Detection In Wide-Field Image-Guided Neurosurgery, Michael Jermyn, Yoann Gosselin, Pablo A. Valdes, Mira Sibai, Kolbein Kolste

Open Dartmouth: Faculty Open Access Articles

In glioma surgery, Protoporphyrin IX (PpIX) fluorescence may identify residual tumor that could be resected while minimizing damage to normal brain. We demonstrate that improved sensitivity for wide-field spectroscopic fluorescence imaging is achieved with minimal disruption to the neurosurgical workflow using an electron-multiplying charge-coupled device (EMCCD) relative to a state-of-the-art CMOS system. In phantom experiments the EMCCD system can detect at least two orders-of-magnitude lower PpIX. Ex vivo tissue imaging on a rat glioma model demonstrates improved fluorescence contrast compared with neurosurgical fluorescence microscope technology, and the fluorescence detection is confirmed with measurements from a clinically-validated spectroscopic probe. Greater PpIX ...


Feasibility Of Atrial Delivery And Tracking Of Stem Cells In A Porcine Model, Nina Garlie, Timothy Hacker, Eric G. Schmuck, Jill Koch, Jayant Khitha, Amish Raval, Indrajit Choudhuri 2015 Regenerative Medicine Center, Aurora Research Institute, Aurora Health Care

Feasibility Of Atrial Delivery And Tracking Of Stem Cells In A Porcine Model, Nina Garlie, Timothy Hacker, Eric G. Schmuck, Jill Koch, Jayant Khitha, Amish Raval, Indrajit Choudhuri

Journal of Patient-Centered Research and Reviews

Background: Many patients undergoing open heart surgery have sinus node dysfunction and atrial fibrillation, leading to adverse outcomes. Mesenchymal stem cells (MSC) delivered at the time of surgery may have a reparative effect on atrial tissue, thereby improving sinus node function and reducing or preventing atrial fibrillation. Stem cell delivery to the atrium is entirely unstudied. This is a significant gap in medical research, as atrial disease contributes significantly to health care costs.

Purpose: The purpose of this pilot study is to establish a technique to deliver MSC to the atria through an open-chest model, to assess the safety of ...

Initial Validation Of A Novel Method Of Presurgical Language Localization Through Functional Connectivity (Fcmri), Stephanie M. Noble, Dustin Scheinost, Susan Y. Bookheimer, Patricia Walshaw, R Todd Constable, Christopher F. Benjamin

Yale Day of Data

OBJECTIVE: Neurosurgery is potentially curative in chronic epilepsy but can only be offered to patients if the surgical risk to language is known. Clinical functional magnetic resonance imaging (fMRI) is an ideal, noninvasive method for localizing language cortex yet remains to be validated for this purpose. We have recently presented a novel method for localizing language cortex. Here we present a preliminary evaluation of this method’s validity. We hypothesized language regions identified using this novel method would demonstrate stronger functional connectivity than randomly generated set of proximal networks. METHOD: fMRI data were collected from sixteen temporal lobe patients (12 ...


Review Of Fluorescence Guided Surgery Visualization And Overlay Techniques, Jonathan T. Elliott, Alisha V. Dsouza, Scott C. Davis, Jonathan D. Olson, Keith Paulsen, David Roberts, Brian Pogue 2015 Dartmouth College

Review Of Fluorescence Guided Surgery Visualization And Overlay Techniques, Jonathan T. Elliott, Alisha V. Dsouza, Scott C. Davis, Jonathan D. Olson, Keith Paulsen, David Roberts, Brian Pogue

Open Dartmouth: Faculty Open Access Articles

In fluorescence guided surgery, data visualization represents a critical step between signal capture and display needed for clinical decisions informed by that signal. The diversity of methods for displaying surgical images are reviewed, and a particular focus is placed on electronically detected and visualized signals, as required for near-infrared or low concentration tracers. Factors driving the choices such as human perception, the need for rapid decision making in a surgical environment, and biases induced by display choices are outlined. Five practical suggestions are outlined for optimal display orientation, color map, transparency/alpha function, dynamic range compression, and color perception check.

Pharmacy Faculty Articles and Research

Liver diseases are known to affect the function of remote organs. The aim of the present study was to investigate the effects of Pringle maneuver, which results in hepatic ischemia–reperfusion (IR) injury, and partial hepatectomy (Hx) on the pharmacokinetics and brain distribution of sodium fluorescein (FL), which is a widely used marker of blood–brain barrier (BBB) permeability. Rats were subjected to Pringle maneuver (total hepatic ischemia) for 20 min with (HxIR) or without (IR) 70% hepatectomy. Sham-operated animals underwent laparotomy only. After 15 min or 8 h of reperfusion, a single 25-mg/kg dose of FL was injected ...

Location Of All-Cause 30-Day Readmission Following Total Joint Replacement: Surgical Hospital Versus Outside Hospital, Leslie R. Harrold, David C. Ayers, Philip Noble, Regis O'Keefe, Tom Bowen, Matthew Sloan, Patricia D. Franklin

Leslie R. Harrold

Background: Evaluating posthospital complications and hospital readmissions in the United States is limited under the current system. This is due to an inability to quantify posthospital care delivered to patients at locations other than the surgical hospital. In order to circumvent this issue, information can be sought directly from patients about posthospital health care utilization. This approach provides a more complete record in comparison with methods that evaluate complications treated only at the surgical hospital. Methods: Participants undergoing total joint replacement (TJR) between 5/10/11 and 5/17/11 were identified from the Function and Outcomes Research in Comparative ...

Dynamic Simulation And Neuromuscular Control Of Movement: Applications For Predictive Simulations Of Balance Recovery, Misagh Mansouri Boroujeni 2015 University of Tennessee - Knoxville

Dynamic Simulation And Neuromuscular Control Of Movement: Applications For Predictive Simulations Of Balance Recovery, Misagh Mansouri Boroujeni

Doctoral Dissertations

Balance is among the most challenging tasks for patients with movement disorders. Study and treatment of these disorders could greatly benefit from combined software tools that offer better insights into neuromuscular biomechanics, and predictive capabilities for optimal surgical and rehabilitation treatment planning. A platform was created to combine musculoskeletal modeling, closed-loop forward dynamic simulation, optimization techniques, and neuromuscular control system design. Spinal (stretch-reflex) and supraspinal (operational space task-based) controllers were developed to test simulation-based hypotheses related to balance recovery and movement control. A corrective procedure (rectus femoris transfer surgery) was targeted for children experiencing stiff-knee gait and how this procedure ...

Gene therapy is one of the most promising approaches for the treatment of lysosomal storage disorders (LSDs). This is especially true for the 75 % of LSDs that have central nervous system (CNS) involvement, where enzyme replacement therapy (ERT), the standard of care for LSDs, is ineffective in treating the neurological features of these diseases. Recombinant adeno-associated virus (AAV) vectors have emerged as the most efficient and promising gene transfer vehicles for the CNS and in particular for LSDs. Direct infusion of AAV vectors into interconnected structures in the brain has achieved widespread distribution of vector and therapeutic levels of lysosomal ...
