A Pilot Study To Investigate Concerns In Patients Undergoing Neck Dissection Surgery, Daniel Sundar Raj Arulananda Doss

Electronic Thesis and Dissertation Repository

Abstract:

This study investigates concerns in patients undergoing neck dissection surgery. Forty patients were recruited at Pre-surgery, Discharge and 1-month Post-surgery. The Patient Concerns Inventory - Level of Importance questionnaire (PCI-LOI), Shoulder Pain and Disability Index (SPADI), Neck Dissection Impairment Index (NDII) and the University of Washington - Quality of Life questionnaire (UWQOL) were used.

The study identified "Anxiety" at Pre-surgery and "Appearance" at Discharge and 1-month Post-surgery as the important patient concerns. Patients’ concerns were found to change over time. Support for cross-sectional convergent validity of the PCI-LOI was evidenced by significant correlations between the PCI-LOI and the UWQOL …

Bismuth Nanoparticles As Medical X-Ray Contrast Agents: Synthesis, Characterization And Applications, Anna Laura Brown

Dissertations and Theses

Bismuth based nanomaterials have recently attracted attention as heavy element X-ray contrast agents because of the high atomic number and predicted biological compatibility of bismuth. Nanoparticle X-ray contrast agents may enable a number of novel medical imaging applications, including blood pool and site-directed imaging. However these hypothetical applications are hindered by lack of suitable synthetic methods for production of imaging agents. This dissertation describes synthesis of a novel class of bismuth nanoparticles that are aqueously stabilized using poly and monosaccharides. These particles are synthesized using highly biologically compatible reagents and are oxidatively stable in water and in moderately basic buffered …

Virtual Reality Aided Mobile C-Arm Positioning For Image-Guided Surgery, Zhenzhou Shao

Doctoral Dissertations

Image-guided surgery (IGS) is the minimally invasive procedure based on the pre-operative volume in conjunction with intra-operative X-ray images which are commonly captured by mobile C-arms for the confirmation of surgical outcomes. Although currently some commercial navigation systems are employed, one critical issue of such systems is the neglect regarding the radiation exposure to the patient and surgeons. In practice, when one surgical stage is finished, several X-ray images have to be acquired repeatedly by the mobile C-arm to obtain the desired image. Excessive radiation exposure may increase the risk of some complications. Therefore, it is necessary to develop a …

Development And Application Of A Biorobotic Simulation Of Stance Phase Gait To Study Foot And Ankle Kinematics, Kelly N. Salb

Theses and Dissertations (ETD)

Ankle instantaneous axis of rotation (IAR) measurements represent a more complete parameter for characterizing joint motion. However, few studies have implemented this measurement to study normal, injured, or pathological foot-ankle biomechanics. Additionally, while load is suggested to play a major role in ankle biomechanics, including influences on articular surfaces, bony motion, and formation of the arches, studies concerning the effects of joint loading are limited.

A novel testing protocol was developed to simulate in vivo mechanics of the foot-ankle complex during early stance phase gait in a human cadaveric model. Two studies were conducted. The first study was to assess …

Scanned Ion Beam Therapy For Thoracic Tumors, John Gordon Eley

Dissertations & Theses (Open Access)

Although frequently cured of Hodgkin lymphoma, adolescents and young adults can develop radiation induced second cancers. These patients could potentially benefit from scanned ion radiotherapy yet likely would require motion mitigation strategies. In theory, four-dimensional (4D) optimization of ion beam fields for individual motion states of respiration can enable superior sparing of healthy tissue near moving targets, compared to other motion mitigation strategies. Furthermore, carbon-ion therapy can sometimes provide greater relative biological effectiveness (RBE) for cell sterilization in a target but nearly equivalent RBE in tissue upstream of the target, compared to proton therapy. Thus, we expected that for some …

Functional 3-D Cellulose & Nitrocellulose Paper-Based, Multiplex Diagnostic Platforms Without Coupling Agents, Mackenzie Elizabeth Tageson

Master's Theses

The purpose of this thesis was to demonstrate device functionality of 3-D paper-based, multiplex platforms, µPADs, without the use of coupling agents between layers. Previously, these platforms were fabricated with double-sided tape and cellulose powder to try to augment proper fluid routing, but difficulties with this method occurred. An acrylic housing unit with strategically placed pressure tabs was designed to aid horizontal and vertical fluid routing through the platform, thus eliminating the inconsistencies associated with coupling agents. Channel characterization studies, a COMSOL^TM simulation, and development time studies were performed to aid device design and demonstrate device functionality.

The implementation …

UNLV Theses, Dissertations, Professional Papers, and Capstones

Lateral cephalometric radiographs have been used for years to help diagnose skeletal and dental patterns in Orthodontics. Within the last decade, these radiographs have caught the interest of the department of Anthropology for the identification of gender within the adult and adolescent population. Numerous publications have been made but failed to identify sexual dimorphism in the pre-adolescent population. 303 lateral cephalograms of pre and post Latino adolescence age ranging from 6.5 to 17.9 years old were obtained from University of Nevada, Las Vegas (UNLV) digital database. 25 variables were identified and plotted with all linear and angular measurements transferred into …

An Evaluation Of The Frankfort Mandibular Plane Angle Bisector (Fmab) Wits Appraisal In The Assessment Of Anteroposterior Jaw Relationships, Natalie Swoboda

Electronic Thesis and Dissertation Repository

An accurate anteroposterior measurement of jaw relationships is essential in orthodontic diagnosis and treatment planning. The purpose of this longitudinal study was to establish a new cephalometric Wits appraisal using a bisector of the mandibular plane angle, named the Frankfort Mandibular Plane Angle Bisector (FMAB). The FMAB was used to assess the sagittal jaw relationship in a sample of Class I individuals, and compare this measurement to the ANB angle and the Wits appraisal using the Maxillomandibular Bisector (MMB).

The data were collected from pre-treatment (T0), immediate post-treatment (T1) and two year post-retention (T2) lateral cephalograms of 61 male and …

Investigation Of The Structure And Dynamics Of Regioisomeric Eu³⁺ And Gd³⁺ Chelates Of Nb-Dotma: Implications For Mri Contrast Agent Design, Benjamin Charles Webber

Dissertations and Theses

The detection of disease and abnormal pathology by magnetic resonance imaging (MRI) has been aided significantly by the use of gadolinium (Gd³⁺)-based contrast agents (CAs) over the past three decades. MRI and MRI CAs play a critical role in diagnosing tumors and diseases of the central nervous system. The agents used clinically have been shown to safely increase MRI contrast despite the toxicity of Gd³⁺, owing to the high kinetic and thermodynamic stability of these chelates. However, current CAs enhance contrast at a small fraction of what is theoretically possible. This leads to the necessity of …

A Novel Signal Processing Method For Intraoperative Neurophysiological Monitoring In Spinal Surgeries, Krishnatej Vedala

FIU Electronic Theses and Dissertations

Intraoperative neurophysiologic monitoring is an integral part of spinal surgeries and involves the recording of somatosensory evoked potentials (SSEP). However, clinical application of IONM still requires anywhere between 200 to 2000 trials to obtain an SSEP signal, which is excessive and introduces a significant delay during surgery to detect a possible neurological damage. The aim of this study is to develop a means to obtain the SSEP using a much less, twelve number of recordings. The preliminary step involved was to distinguish the SSEP with the ongoing brain activity. We first establish that the brain activity is indeed quasi-stationary whereas …

In Vitro Manual Therapy And Biorobotic Simulation Of Glenohumeral Joint Mobilization Techniques, Hunter Johnson Smith

Theses and Dissertations (ETD)

Physical therapists (PT) employ mobilization techniques for restoring range of motion to joints. Few studies have attempted to quantify the biomechanics of manual therapy on the glenohumeral (GH) joint. The objectives of this study were to develop an in vitro protocol to determine the biomechanical effects of joint mobilization on the GH joint, and to then simulate these mobilizations in the University of Tennessee Health Science Center (UTHSC) Joint Implant Biomechanics Laboratory’s Robotic Testing Platform (RTP).

The GH joint is an incredibly shallow socket joint. This gives the joint an unusually large range of motion (ROM) compared to other ball …
