Book excerpt: Vocal fold scar remains one of the most demanding and, in some ways, frustrating challenges of laryngology and voice therapy. Treatments for this complex condition are inconsistent and often produce suboptimal results. Yet, while hopes for full recovery remain slim, surgical methods and improving technologies, along with improved therapy techniques, have combined to yield better and better outcomes; and further advances are on the horizon. In this new book, Moore, Sataloff, and Hawshaw have collaborated with world leaders in laryngology and speech-language pathology to compile the latest information on the pathophysiology of vocal fold scar, treatments, procedures and, importantly, look at the promising directions in research. The authors introduce the various causes and sequelae of scar, examine anatomy and pathophysiology, and take the reader through diagnostic procedures. Thereafter, they review preoperative therapy options and providing practical guidance on surgical methods including medialization, techniques for freeing the epithelium, management of sulcus, grafting, and the use of lasers. The book discusses tissue engineering and newer treatment options, including epidermal growth factor (EGF) and transforming growth factor-beta 1 (TGF- 1). The book summarizes the state of the art in diagnosis and treatment of vocal fold scar and should be valuable for any clinician who cares for the patient with this vexing problem."

Download or read book Identification of Biomechanically Valid Cell Therapeutics for Vocal Fold Scarring written by Rebecca Susan Bartlett and published by . This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Candidate cell sources for vocal fold scar treatment include mesenchymal stromal cells from bone marrow (BM-MSC) and adipose tissue (AT-MSC). The mechanosensitivity of MSC can alter highly relevant aspects of their behavior, yet virtually nothing is known about how MSC might respond to the dynamic mechanical environment of the larynx. Our objective was to evaluate MSC as a potential cell source for vocal fold tissue engineering using a mechanically relevant in vitro model (Study 1) and in vivo model (Study 2). In Study 1, a bioreactor capable of reproducing the vocal mechanoenvironment was used to evaluate the genomic similarity between MSC and vocal fold fibroblasts (VFF) following vibratory strain. Posterior probabilities for each of the 53,617 microarray transcripts fitting into specific expression patterns were calculated. VFF shared more Gene Ontology (GO) wound healing terms with BM-MSC than with AT-MSC. For example, vibrated VFF and BM-MSC shared similar capacities for glycosaminoglycan and proteoglycan activity, which could favorably effect collagen remodeling in vocal scar. Analysis of GO terms relating to MSC differentiation toward osteogenic, adipogenic, and chondrogenic lineages revealed that BM-MSC expressed fewer osteogenesis terms in the vibrated and scaffold conditions as compared to the polystyrene condition. This was consistent with our hypothesis that tissue-relevant stress encourages tissue-relevant cell differentiation. Lastly, mechanotransductive mechanisms underlying phonatory biology were preliminarily discussed with regard to microarray data, with integrin and lamellipodia activity distinguishing vibrated from non-vibrated cells. Microarray data was confirmed with real-time PCR. Immunostaining for Ki67 (proliferation) was positive in 15- 23% of cells, and cleaved caspase 3 (apoptosis) was positive in 2-7% of cells, and neither varied with cell type or mechanical condition. In Study 2, mature rabbit vocal scars were treated with four variations of MSC therapy. Nine weeks following injection, vocal folds receiving BM-MSC without a hyaluronic acid hydrogel produced the highest levels of a desirable adipogenesis marker (lipoprotein lipase) and an undesirable osteogenesis marker (osteocalcin). Osteocalcin was expressed 452-fold lower than in bone tissue, suggesting a clinically insignificant vocal fold level. As our field progresses toward clinical trials of cell-based vocal scar therapies, consideration of mechanotransductive and differentiation profiles is prudent.

Download or read book Vocal Fold Injury and Scar Modulation in an Ovine Model written by Jacqueline Elizabeth Allen and published by . This book was released on 2020 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vocal fold injury that results in scarring, creates a permanent vocal deficit that currently has no reliable or efficacious treatment. Impaired voicing has significant occupational, social and personal impacts. More than 25% of adults identify themselves as vocal professionals, needing voice for work, and almost all social situations are based on spoken communication. Many recreational pursuits are also voice-dependent and loss of the ability to contribute is socially isolating. This corpus of work has examined the mechanisms involved in wound healing in the vocal fold (VF), in the context of general wound healing, but focusing on the unique microarchitecture that the VF exhibits. In gaining understanding of the molecular mechanisms, I have chosen to target a fibrotic pathway, the TGF-b cascade, and its transducer the Smad signalling proteins, to evaluate whether favourable modulation of VF wound healing is possible. This research aimed to validate an ovine laryngeal injury model, and determine the tolerability and efficacy of a specific Smad3 inhibitor - halofuginone - in modifying the fibrotic cascade, and ascertain whether any identified histological changes translated to meaningful rheological alterations. All sheep underwent controlled right VF injury and were then exposed to one of four experimental conditions. Sheep were assigned in a paired study design (left VF vs right VF) to receive no medications, halofuginone at varying dose levels, dexamethasone or triamcinolone. Comparison medications were selected based on current clinical practice. Ovine larynges were then harvested and examined for histological findings, immunohistochemical analysis and ex-vivo rheological evaluation. VF wounding demonstrated a predictable and consistent pattern from injury to restitution which was responsive to administered medication. Halofuginone and dexamethasone moderated collagen deposition (anti-fibrotic). However, halofuginone also protected against elastin depletion after injury. Ovine larynges produced consistent oscillation following treatment and healing, confirming that histological findings were reflected in functional phonation. VF injury in an ovine model results in a predictable wound response, mediated by the TGF-b pathway and able to be modified by Smad3 inhibitor, halofuginone, with benefit to vibratory function. This suggests this pathway is a suitable target for manipulation to prevent or reverse fibrosis in the glottis and restore voice quality.

Download or read book Classification Manual for Voice Disorders I written by Katherine Verdolini and published by Psychology Press. This book was released on 2014-04-08 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: To date, there are 300 disorders associated with voice, but until now there has never been a published reference manual that classifies these disorders. Borrowing from the successful organization schema of the American Psychiatric Association’s Diagnostic Statistical Manual (DSM), the Classification Manual for Voice Disorders-I provides the framework for classifying voice disorders using the following criteria for each disorder: essential and associated features; vocal impairment; clinical history and demographic profile; course and complications; medical and voice differential diagnosis; and severity criteria. Classification Manual for Voice Disorders-I is a project of ASHA’s Special Interest Division 3, Voice and Voice Disorders (DIV 3), originally directed by contributing authors Moya Andrews, Diane Bless, Daniel Boone, Janina Casper, Leslie Glaze, Mike Karnell, Christy Ludlow, and Joe Stemple. The text was edited over a period of several years by the authoritative group of voice disorders professionals, including Katherine Verdolini, Clark Rosen, and Ryan Branski. This version represents the fields of speech-language pathology, voice science, and otolaryngology. CMVD-I lists most conditions that may negatively affect the ability to produce voice, based on the most current knowledge. These conditions comprise 30 structural pathologies, 25 neurological disorders, 20 aerodigestive conditions, 13 psychological disturbances, 15 systemic diseases, four inflammatory processes, four traumatic conditions, and five miscellaneous voice disorders. CMVD-I is a must-have resource for professionals who specialize in voice disorders, especially speech-language pathologists and otolaryngologists. The handy organization of this reference makes it a convenient and accessible resource for voice coaches and teachers of singing. It will also be invaluable as a textbook in master’s-level communication sciences programs throughout the world. Proceeds received by Division 3 will be used to support the mission of Special Interest Division 3, which provides continuing education and networking opportunities to promote leadership and advocacy for voice issues from professional, clinical, educational, and scientific perspectives.

Download or read book Computational Agent based Modeling of Surgical Vocal Fold Injury and Repair written by Aman Garg and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Voice disorders affect about one in ten adults at some point in their lifetime. Vocal fold scarring can result from surgical excision of benign and malignant vocal fold lesions. The elicited inflammation and healing response is complex and dynamic. It involves immune and repair cells (e.g., neutrophils, macrophages, fibroblasts) and molecules (e.g., inflammatory cytokines, damage-associated molecular pattern molecules) to locate damaged tissue, eliminate the necrotic cells and debris, and produce extracellular matrix substances for eventual tissue repair. A mechanistic understanding of the vocal fold injury and repair process will help in identifying the effective treatments for iatrogenic vocal fold scarring from surgery.The overall goal of this thesis was to develop computational agent-based models (ABM) that could numerically simulate the dynamics of major cellular and molecular components involved in surgical vocal fold injury and repair. The first research goal was to phenotype and enumerate immune and repair cells in surgically injured rat vocal folds up to 4 weeks after surgical injury. Viable cells were isolated from harvested vocal folds and were stained for cell surface markers specific to neutrophils, macrophages, endothelial cells and fibroblasts. Multi-parametric flow cytometry was then conducted to count the number of cells for each cell population in the vocal fold samples. The second research goal was to calibrate and validate existing agent-based models of vocal fold injury and repair (VF-ABM) with the flow cytometry data. Global sensitive analysis using Random Forests were first employed to identify the most influential model parameters on the outputs of cell numbers. The Robust Parameter Estimation (ROPE) algorithm from the package of Statistical Parameter Optimization Tool for Python (SPOTPY) was then used to calibrate VF-ABM for early time points from Day 1 to Day 5 of the flow cytometry data. Subsequently, VF-ABM were run 100 times to generate 95% confidence intervals for model evaluation. VF-ABM predicted outputs were considered accurate if the empirical data points were within the 95% confidence intervals of simulated outputs. Cell population quantities were calculated for Day 7, Week 2 and Week 4 respectively against the empirical flow cytometry data. Predicted cell populations reached 100% accuracy for Day 7. Although VF-ABM generated qualitative trends of cell population comparable to those of Weeks 2 and 4, the corresponding empirical data values fell outside of the 95% confidence intervals. Results from the flow cytometry study provided quantitative and time-dependent data on major cell populations involved in surgical vocal fold injury. Results from the model verification informed the area of improvements for the next generation of VF-ABM. This thesis contributes to the development of a computational tool that would better inform clinicians in prescribing treatments for patients with voice disorders." --
