Monitoring Carboplatin Ototoxicity With Distortion-Product Otoacoustic Emissions In Children With Retinoblastoma, Shaum Bhagat, Johnnie Bass, Stephanie White, Ibrahim Qaddoumi, Matthew Wilson, Jianrong Wu, Carlos Rodriguez-Galindo

Faculty Publications

ObjectiveCarboplatin is a common chemotherapy agent with potential ototoxic side effects that is used to treat a variety of pediatric cancers, including retinoblastoma. Retinoblastoma is a malignant tumor of the retina that is usually diagnosed in young children. Distortion-product otoacoustic emission tests offer an effective method of monitoring for ototoxicity in young children. This study was designed to compare measurements of distortion-product otoacoustic emissions obtained before and after several courses of carboplatin chemotherapy in order to examine if (a) mean distortion-product otoacoustic emission levels were significantly different; and (b) if criterion reductions in distortion-product otoacoustic emission levels were observed in …


Intelligibility Of Electrolarynx Speech Using A Novel Actuator, Brian Madden, Mark Nolan, Ted Burke, James Condron, Eugene Coyle Jun 2010

Intelligibility Of Electrolarynx Speech Using A Novel Actuator, Brian Madden, Mark Nolan, Ted Burke, James Condron, Eugene Coyle

Conference Papers

During voiced speech, the larynx provides quasi-periodic acoustic excitation of the vocal tract. Following a laryngectomy, some people speak using an electrolarynx which replaces the excitatory function of the absent larynx. Drawbacks of conventional electrolarynx designs include the buzzing monotonic sound emitted, the need for a free hand to operate the device, and difficulty experienced by many laryngectomees in adapting to its use. Despite these shortcomings, it remains the preferred method of speech rehabilitation for a substantial minority of laryngectomees. In most electrolarynxes, mechanical vibrations are produced by a linear electromechanical actuator, the armature of which percusses against a metal …


Vocabulary Acquisition Of Bilingual Students Through The Implementation Of Dialogic Shared Storybook Reading Techniques, Samantha Kamille Ariaz Jan 2010

Vocabulary Acquisition Of Bilingual Students Through The Implementation Of Dialogic Shared Storybook Reading Techniques, Samantha Kamille Ariaz

Open Access Theses & Dissertations

Children who are learning English as a second language and whose caregivers speak only Spanish were chosen to participate in the study. Parents were trained using Dialogic Shared Storybook Reading (DSSR) techniques (Whitehurst, 1988). The study was a single subject multiple baseline design across behaviors. Reading conditions were counterbalanced to control for acquisition of new vocabulary. There were a total of five participants, three children and two mothers (n=5). The participants were separated into two families. Each family was exposed to three reading book conditions while the parents implemented the specified techniques: 1. Shared reading with an electronic, bilingual Spanish/ …


A Survey Of Variables Influencing Speech-Language Pathologists' Use Of Evidence-Based Practice In Clinical Settings, Ailbhe Tressan Cormack Jan 2010

A Survey Of Variables Influencing Speech-Language Pathologists' Use Of Evidence-Based Practice In Clinical Settings, Ailbhe Tressan Cormack

Open Access Theses & Dissertations

Although the need for evidence-based practice (EBP) in speech-language pathology has been well attested, multiple barriers hamper its implementation. Purpose: The purpose of this study was to compare variables influencing the use of EBP by practicing speech-language pathologists (SLPs). Method: Eighty-five SLPs based out of different primary work settings in El Paso, Texas responded to a survey addressing: 1. attitudes and perceived barriers toward EBP, 2. exposure to EBP, research methodology and statistics in graduate courses, 3. time in practice, 4. practice setting(s), 5. amount and nature of support for EBP in work settings, and 6. use of research literature …


Perception And Identification Of Voice Disorders: A Comparison Study Between Hispanic And Non-Hispanics, Jacqueline Nicole Lopez Jan 2010

Perception And Identification Of Voice Disorders: A Comparison Study Between Hispanic And Non-Hispanics, Jacqueline Nicole Lopez

Open Access Theses & Dissertations

The extent of public education in the Hispanic population regarding voice disorders has been unidentified thus far, motivating the current study to assess knowledge and perception of functional and organic voice disorders among Hispanic individuals in the El Paso region. The project involved an experimental research design to investigate whether demographic variables influenced the accuracy of knowledge of voice disorders in the general population residing in the Greater El Paso Region. Results indicate that the majority of the participants perceive articulation, fluency, and voice disorders as interchangeable and are unaware of the role of medical and rehabilitation professionals in the …


Coherence In Stories Told By Adults With Aphasia, Heather Harris Wright, Anthony Koutsoftas, Gerasimos Fergadiotis, Gilson Capilouto Jan 2010

Discourse coherence is the conceptual organization of discourse and it can be subdivided into two types: global and local. Of interest for the current study is global coherence; that is, how the discourse relates to the overall topic (Glosser & Deser, 1990). Coherence has been measured in persons with aphasia (PWA) using different elicitation tasks (e.g., recounts, story retelling, event-casts) and different scoring methods (ie., rating scales, coherence, violations, total counts) and results have varied across studies (Christianson, 1995; Coelho & Flewellyn, 2003; Glosser & Deser, 1990; Ulatowska, et al., 2004). These differences may reflect differences in how coherence is …


Psychometric Properties Of The Pyramids And Palm Trees Test, Gerasimos Fergadiotis, Heather Wright, Gilson Capilouto Jan 2010

Psychometric Properties Of The Pyramids And Palm Trees Test, Gerasimos Fergadiotis, Heather Wright, Gilson Capilouto

Speech and Hearing Sciences Faculty Publications and Presentations

The Pyramids and Palm Trees Test (PPT) is a nonverbal measure of semantic memory that has been frequently used in previous aphasia, agnosia, and dementia research. Very little psychometric information regarding the PPT is available. The purpose of this study was to investigate the psychometric properties of the PPT in a population of healthy college students. Results indicated that the PPT achieved poor test–retest reliability, failed to obtain adequate internal consistency, and demonstrated poor convergent validity, but showed acceptable discriminant validity. The results of this study suggest that the PPT lacks acceptable reliability and validity for use with a college …
