Emergency Department Approach To Electrical Toothbrush Associated Hand Injury, A Unique Case Of Non-Oropharyngeal Injury., Hannah Robinson, Neal Sikka, Chimere Little, Ali Pourmand 2017 George Washington University

Emergency Department Approach To Electrical Toothbrush Associated Hand Injury, A Unique Case Of Non-Oropharyngeal Injury., Hannah Robinson, Neal Sikka, Chimere Little, Ali Pourmand

GW Research Days 2016 - Present

Puncture wounds are common injuries treated in the emergency department (ED). Prior studies have shown that toothbrushes are common reservoirs for oral flora, especially in regions near the head of the toothbrush near the bristles. ED providers must be aware of the danger associated with bacterial contamination of the associated wound and should be familiar with different pathogens and options for treatment. We present a unique case of a 30-year-old male with non-intraoral injury who presented to the ED after puncturing his left palm with the metal post of an electric toothbrush.

Difference Image Ultra-Short Echo Time T2* Mapping Using A 3d Cones Trajectory, Amin Nazaran, Grayson Tarbox, Randy Hartley, Neal Bangerter

Biomedical Engineering Western Regional Conference

This study introduces a methodology for detecting subtle variations in tissues with very rapid T2* decay through a difference image ultra-short T2* mapping technique using a 3D cones k-space trajectory. The new method is demonstrated in both a normal and surgically repaired Achilles tendon. The resulting UTE images are differenced and T2* values were calculated using a mono-exponential least squares fit on a voxel by voxel basis. The ultrashort T2* maps yield very consistent short T2* values in healthy tendon of 0.3-0.5 ms, while notable variations and elevations of T2* values are observed in surgically repaired tendon.

Background: Catheter ablation of the cavotricuspid isthmus (CTI) is traditionally performed using fluoroscopy and electroanatomical mapping systems. Zero-fluoroscopy approaches have recently been studied, mostly using the EnSite® mapping system (St. Jude Medical Inc., St. Paul, MN). We studied the feasibility and efficacy of zero-fluoroscopic mapping and ablation of the CTI using the Carto® 3 system (Biosense Webster Inc., South Diamond Bar, CA).

Purpose: To evaluate the efficacy and safety of a zero-fluoroscopic approach to CTI ablation.

Methods: We included 9 patients with typical atrial flutter for whom mapping and ablation of the CTI was done using Carto mapping as the ...


Precision Study Of Stochastic Predictors For Dxa Scans, Raul Ramos 2016 University of Texas at Tyler

Precision Study Of Stochastic Predictors For Dxa Scans, Raul Ramos

Health and Kinesiology Theses

In this study, the in vivo reproducibility of stochastic predictors and BMD values from Dual- Energy X-ray Absorptiometry (DXA) were assessed at two different anatomic sites: hip and spine. Measurement of bone mineral density (BMD) derived from DXA has been widely used as a diagnostic tool for osteoporosis. BMD has been used as a representative value for bone strength and fracture risk, but only represents a part of both. In order to better understand fracture risk, the use of grayscale images from DXA scans has been implemented in enhancing the prediction of bone strength and fracture risk. The use of ...


Development And Optimization Of 19f-Mri For Tracking Cellular Therapeutics, Jeffrey M. Gaudet 2016 The University of Western Ontario

Development And Optimization Of 19f-Mri For Tracking Cellular Therapeutics, Jeffrey M. Gaudet

Electronic Thesis and Dissertation Repository

Introduction: This thesis aims to advance magnetic resonance imaging (MRI) for imaging cellular therapeutics. Traditional, proton-based, MRI provides detailed anatomical images, particularly of soft tissue. However, in order to obtain information at a cellular level specialized imaging agents are required to detect the cells of interest. Perfluorocarbons containing non-radioactive fluorine-19 (19F) are both biologically safe and MR sensitive. Methods: Pre-clinical 19F-MRI was implemented on a Varian 9.4T MRI scanner, using a dual 19F/1H-tuned birdcage volume coil. Mesenchymal stromal cells (MSC) were pre-labeled with a commercial, FDA approved 19F-perfluorocarbon emulsion, then implanted intramuscularly into ...


A Subject Specific Surface Electromyography Model For Estimating L4/L5 Compressive Loading, Pablo Joaquin Dopico 2016 University of Tennessee Health Science Center

A Subject Specific Surface Electromyography Model For Estimating L4/L5 Compressive Loading, Pablo Joaquin Dopico

Theses and Dissertations (ETD)

Introduction: Low Back Pain (LBP) is a leading cause of activity limitation worldwide and results in 149 million lost work days annually in the United States. The total costs of LBP are estimated to be $100 to $200 billion annually. Specific causes of LBP account for less than 15% of LBP cases. Heavy loading of the lumbar spine and tight hamstrings have been identified as risk factors for LBP. Tight hamstrings pull the pelvis posteriorly and reduce the lordosis of the spine, resulting in increased loading of the lumbar vertebral bodies of the spine. While this mechanism has been described ...


Evaluation Of A Multiplex Real-Time Pcr Assay To Simultaneously Detect Streptococcus Pneumoniae And Staphylococcus Aureus In Nasal Samples, Polly Hockberger 2016 Northern Michigan University

Evaluation Of A Multiplex Real-Time Pcr Assay To Simultaneously Detect Streptococcus Pneumoniae And Staphylococcus Aureus In Nasal Samples, Polly Hockberger

All NMU Master's Theses

Invasive disease caused by Streptococcus pneumoniae and Staphylococcus aureus is associated with nasal carriage of these bacteria. Use of a pneumococcal conjugate vaccine (PCV) in children altered nasal carriage rates and reduced infections due to S. pneumonia. Similar studies demonstrate that there is an inverse correlation between S. pneumoniae and S. aureus nasal carriage in children, but this inverse correlation has not been extensively investigated adults. The PCV is now approved for use in adults, a group more likely to be colonized with S. aureus. To investigate the impact of PCV vaccination on S. aureus carriage in adults, the clinical ...


Noise: Its Impact In The Operating Room, Brennon Wesley Sloan 2016 University of Southern Mississippi

Noise: Its Impact In The Operating Room, Brennon Wesley Sloan

Doctoral Nursing Capstone Projects

Orthopedic and neurologic cases routinely reach noise levels exceeding 120 decibels (Katz, 2014). Modern equipment and monitors used by anesthesia personnel only reach 85 decibels (Katz, 2014). These monitors can go undetected during peak noise levels creating a serious safety concern for patients that could lead to patient injury or death (Gawande, Zinner, Studdert, & Brennan, 2003). A clinical question was developed to determine if the education of noise levels in the operating room affects change in practice. For operating room managers and staff, does education of noise levels in the operating room compared to no education initiate a change in ...

Abdominal and pelvic abscesses can occur as a consequence of surgery and are associated with significant morbidity and mortality. It is well accepted that the primary treatment is antibiotic therapy and minimally invasive drainage. Surgical measures are typically reserved for patients with luminal perforations or those who do not respond to conservative measures. Previously available modalities of drainage involved percutaneous and computed tomography guided access. Recently, endoscopic ultrasound guided aspiration has emerged as a safe alternative for management of intra-abdominal abscesses. Since its first application for peripancreatic drainage, endoscopic ultrasound techniques and technologies have significantly evolved. Endoscopic ultrasound interventions can ...


Retrograde Pedal Access For Revascularization Of Infrapopliteal Arterial Occlusive Disease In Critical Limb Ischemia (Cli) Patients As A Primary Approach., Ahmed Amro, Alaa Gabi, Shahed Elhamdani, Haytham Aljoudi, Mehiar El-Hamdani 2016 Marshall University school of Medicine

Retrograde Pedal Access For Revascularization Of Infrapopliteal Arterial Occlusive Disease In Critical Limb Ischemia (Cli) Patients As A Primary Approach., Ahmed Amro, Alaa Gabi, Shahed Elhamdani, Haytham Aljoudi, Mehiar El-Hamdani

Marshall Journal of Medicine

Introduction:

We are presenting three cases (out of similar several cases) where tibio-pedal approach was performed as an initial primary approach for limb salvage in patients with CLI secondary to Infra-popliteal (IP) disease. We consider this approach to be a necessary evolution in endovascular intervention.

Discussion:

Retrograde pedal access is safe, feasible with high technical success rate and a relatively low procedural complication rate, with low 30 days mortality and low rate of major adverse cardiac events. Freedom from major adverse limb events and limb salvage are both high at 1 year follow up. It allows quick therapy and short ...

The Physiological Responses To Cycling Stress., Moriah Larsen

Skyline - The Big Sky Undergraduate Journal

Background: As the intensity of exercise increases, the risk of incidences for exertional heat illness (EHI) continues to climb. The National Athletic Trainers Association (NATA) has set an official position statement; stating a “gold standard” for obtaining core body temperature is via rectal thermometry. It has been reported that other field-expedient methods of obtaining core body temperature (oral, axillary, tympanic, temporal) are invalid or unreliable sources after intense exercise in hot temperature regions. Purpose: To determine if a relationship exists between rectal temperature measurements and tympanic temperature measurements during intensive long bouts of exercise. Design: Controlled Laboratory Study. Setting: Human ...


Characterization And Personalization Of Botulinum Toxin Type A Therapy For Upper Limb Tremor In Parkinson Disease And Essential Tremor Patients Using Multi-Sensor Kinematic Technology, Olivia Samotus 2016 The University of Western Ontario

Characterization And Personalization Of Botulinum Toxin Type A Therapy For Upper Limb Tremor In Parkinson Disease And Essential Tremor Patients Using Multi-Sensor Kinematic Technology, Olivia Samotus

Electronic Thesis and Dissertation Repository

Tremor commonly affects the upper extremities in essential tremor (ET) and Parkinson disease (PD) patients where many experience functional disability and ultimately seek therapy. As ET and PD tremor features overlap and clinical assessment is challenging due to its highly complex nature, misdiagnosis is common resulting in unsuitable therapies and prognosis. Current treatment options for ET and PD tremor include pharmacotherapy, focal therapy with botulinum toxin type A (BoNT-A) injections, and surgical interventions which provide modest relief of tremor. However, such therapies are commonly associated with significant adverse events and lack long-term efficacy and tolerability. Hence lack of standardized, objective ...


Effect Of Taste Stimuli On Swallowing Function In Persons With Traumatic Injuries, Megan Asselin, Angela M. Dietsch 2016 University of Nebraska-Lincoln

Effect Of Taste Stimuli On Swallowing Function In Persons With Traumatic Injuries, Megan Asselin, Angela M. Dietsch

UCARE Research Products

Background

Swallowing disorders are prevalent and costly. As of now, there are limited therapeutic options available to treat them. Extant research in limited populations has suggested that swallowing mechanics can be improved by extremely sour liquids, but this has not been tested in traumatically injured populations. However, sour tastants are unpleasant, and more palatable taste mixtures have not been tested.

Methods

The quantitative data were extracted from an existing pool of de-identified video fluoroscopic swallowing studies (moving radiographs) obtained from traumatically injured young adults under another research protocol. Each participant completed swallows of custom-mixed plain, sour, and sweet-sour boluses. Positions ...

A Comparison Of Imaging Modalities For The Diagnosis Of Osteomyelitis, Brandon J. Smith, Md, Grant S. Buchanan, Md, Franklin D. Shuler, Md, Phd

Marshall Journal of Medicine

Osteomyelitis is an increasingly common pathology that often poses a diagnostic challenge to clinicians. Accurate and timely diagnosis is critical to preventing complications that can result in the loss of life or limb. In addition to history, physical exam, and laboratory studies, diagnostic imaging plays an essential role in the diagnostic process. This narrative review article discusses various imaging modalities employed to diagnose osteomyelitis: plain films, computed tomography (CT), magnetic resonance imaging (MRI), ultrasound, bone scintigraphy, and positron emission tomography (PET). Articles were obtained from Pubmed and screened for relevance to the topic of diagnostic imaging for osteomyelitis. The authors ...

Center for Brain, Biology and Behavior: Papers & Publications

In sports concussion research, obtaining quality data from a sufficient number of participants to reach statistical power has been a particular problem. In addition, the necessary requirements of accessibility, informed consent, and confidentiality must be met. There is need to develop more efficient and controlled methods for collecting data to answer research questions in this realm, but the ability to collect and store these data in an efficient manner at the local level is limited. By virtue of their training, neuropsychologists can play a key role in improving data collection quality. The purpose of this paper is to describe a ...

Real-World Relevance Of Manual Electrocardiography Qt Interval Measurement, Satish Velagapudi, Zahra Nur Khaled, Bilal Omery, Firas Zahwe, Michael Anigbogu, Sarah Zukkoor, Indrajit Choudhuri

Indrajit Choudhuri

Background: Electrocardiography (ECG) QT interval (QTI) prolongation independently predicts sudden death. Hospitalized patients are commonly exposed to multiple QT-prolonging drugs, and manual measurement of ECG QTI based on identifying the intersection of isoelectricity with the tangent to the terminal phase T-wave slope (QTTTT) is advocated due to inaccuracies in automated detection algorithms that may imprecisely identify QT duration.

Purpose: We evaluated the performance of QTTTT compared to a standard automated (12SL, GE Healthcare) method (QT-12SL).

Methods: Consecutively obtained ECGs of 250 hospitalized patients were reviewed. The QTI in leads II, aVR, V5 and V6 determined by QT-12SL and QTTTT were ...
