The relationship between the place of electrical stimulation from a cochlear implant and the corresponding perceived pitch remains uncertain. Previous studies have estimated what the pitch corresponding to a particular location should be. However, perceptual verification is difficult because a subject needs both a cochlear implant and sufficient residual hearing to reliably compare electric and acoustic pitches. Additional complications can arise from the possibility that the pitch corresponding to an electrode may change as the auditory system adapts to a sound processor. In the following experiment, five subjects with normal or near-to-normal hearing in one ear and a cochlear implant …

Infantile hemangiomas (IHs) are the most common tumors of childhood. Unlike other tumors, they have the unique ability to involute after proliferation, often leading primary care providers to assume they will resolve without intervention or consequence. Unfortunately, a subset of IHs rapidly develop complications, resulting in pain, functional impairment, or permanent disfigurement. As a result, the primary clinician has the task of determining which lesions require early consultation with a specialist. Although several recent reviews have been published, this clinical report is the first based on input from individuals representing the many specialties involved in the treatment of IH. Its …

Comparative Analysis Of The Extracellular Matrix Composition In Proliferating And Involuted Infantile Hemangiomas, H. Park, H. Park, H. Y. Chung, T. M. O, M. Waner

Journal Articles

BACKGROUND: Changes in the composition of the extracellular matrix (ECM) occur between the proliferating and involuted phases of infantile hemangiomas (IH), and are associated with angiogenic growth. We examined the composition of the ECM in proliferating and involuted IHs and assessed correlations between the composition of the ECM and whether the IH was in the proliferating or the involuted phase. METHODS: We evaluated IH samples from a cohort of patients who had five proliferating IHs and five involuted IHs. The following ECM molecules were analyzed using enzyme-linked immunosorbent assays and immunohistochemistry: laminin, fibronectin, collagen type I, collagen type II, and …

Presurgical Ct Evaluation Of Congenital Aural Atresia, V. T. Nguyen, G. Paek, J. Hu, L. P. Smith

Journal Articles

Congenital aural atresia occurs in approximately 1 in 10,000‐20,000 births and may be surgically repaired if the middle ear malformation is limited in character. External auditory canal atresia is difficult to repair surgically, with significant risks and complications. Surgical candidacy in congenital aural atresia is based on multiple factors, central to which are the anatomy of the temporal bone and audiometric findings. High-resolution multidetector CT is the imaging technique of choice for anatomy delineation, although there are some specific indications for MR imaging in presurgical assessment. Various CT grading systems have been developed to determine surgical candidacy and are described …

Journal Articles

The epithelium is part of an integrated immune system where cytokines, toll-like receptors and their ligands, and extracellular vesicles play a crucial role in initiating an innate immune response. IL-36gamma is a pro-inflammatory member of the IL-1 family that is mainly expressed by epithelial cells, but regulation of its expression and release are only beginning to be understood. Previous studies reported that IL-36gamma is abundant in recurrent respiratory papillomatosis, a rare but devastating disease caused by human papillomaviruses (HPV) types 6 and 11, in which papillomas recurrently grow in and block the airway. Despite the overexpression of IL-36gamma, papilloma tissues …

Journal Articles

Metastatic Ewing Sarcoma carries a poor prognosis, and novel therapeutics to prevent and treat metastatic disease are greatly needed. Recent evidence demonstrates that tumor-associated macrophages in Ewing Sarcoma are associated with more advanced disease. While some macrophage phenotypes (M1) exhibit anti-tumor activity, distinct phenotypes (M2) may contribute to malignant progression and metastasis. In this study, we show that M2 macrophages promote Ewing Sarcoma invasion and extravasation, pointing to a potential target of anti-metastatic therapy. CNI-1493 is a selective inhibitor of macrophage function and has shown to be safe in clinical trials as an anti-inflammatory agent. In a xenograft mouse model …

The Relationship Between Insertion Angles, Default Frequency Allocations, And Spiral Ganglion Place Pitch In Cochlear Implants, D. M. Landsberger, M. Svrakic, J. T., Jr. Roland, M. Svirsky

Journal Articles

OBJECTIVES: Commercially available cochlear implant systems attempt to deliver frequency information going down to a few hundred Hertz, but the electrode arrays are not designed to reach the most apical regions of the cochlea, which correspond to these low frequencies. This may cause a mismatch between the frequencies presented by a cochlear implant electrode array and the frequencies represented at the corresponding location in a normal-hearing cochlea. In the following study, the mismatch between the frequency presented at a given cochlear angle and the frequency expected by an acoustic hearing ear at the corresponding angle is examined for the cochlear …


Immune Dysregulation In Patients Persistently Infected With Human Papillomaviruses 6 And 11, A. V. Lucs, J. A. Devoti, L. Hatam, A. Afzal, A. L. Abramson, B. M. Steinberg, V. R. Bonagura Jan 2015

Journal Articles

Human Papillomaviruses (HPVs) 6 and 11 are part of a large family of small DNA viruses, some of which are commensal. Although much of the population can contain or clear infection with these viruses, there is a subset of individuals who develop persistent infection that can cause significant morbidity and on occasion mortality. Depending on the site of infection, patients chronically infected with these viruses develop either recurrent, and on occasion, severe genital warts or recurrent respiratory papillomas that can obstruct the upper airway. The HPV-induced diseases described are likely the result of a complex and localized immune suppressive milieu …


N-Acetylcysteine Attenuates Tumor Necrosis Factor Alpha Levels In Autoimmune Inner Ear Disease Patients, S. Pathak, C. Stern, A. Vambutas Jan 2015

N-Acetylcysteine Attenuates Tumor Necrosis Factor Alpha Levels In Autoimmune Inner Ear Disease Patients, S. Pathak, C. Stern, A. Vambutas

Journal Articles

Autoimmune inner ear disease (AIED) is a poorly understood disease marked by bilateral, rapidly progressive hearing loss triggered by unknown stimuli, which is corticosteroid responsive in 60 % of patients. Although the mechanism of the disease is not precisely understood, a complex interaction of cytokines is believed to contribute toward the inflammatory disease process and hearing loss. Previously, we showed the role of TNF-alpha in steroid-sensitive and IL-1beta in steroid-resistant immune-mediated hearing loss. N-Acetylcysteine (NAC), a broad spectrum antioxidant, has been effective in other autoimmune disorders. Other studies have shown NAC to have a protective adjunct role in human idiopathic …

Multiportal Combined Transorbital And Transnasal Endoscopic Resection Of Fibrous Dysplasia, T. Tham, P. Costantino, M. Bruni, D. Langer, J. Boockvar, P. Singh

Journal Articles

Introduction Historically, access to the anterior skull base was achieved with open procedures. The paradigms to this approach were challenged with the advent of minimally disruptive endoscopic surgical techniques and supporting technology. The next step in the evolution of minimally disruptive surgery was the combination of multiportal endoscopic surgery. Results The patient was an 18-year-old man who presented with right-sided proptosis. Further diagnostic tests revealed a fibrous dysplasia (FD) occupying the skull base and orbit. The lesion was successfully resected. Conclusions The location of the tumor in this case was challenging, in which surgeons at some centers would have opted …
