Locoregional recurrence accounts for majority of the treatment failures in oral cancer patients. Current study aimed to determine the predictors of recurrence and survival in patients with biopsy proven Squamous Cell Carcinoma (SCC) of the oral cavity. This study included 88 patients of squamous cell carcinoma treated at our institution from 2007 till 2013. Primary intervention was surgery in all patients with radiation and chemotherapy in selected patients. Primary end point was locoregional recurrence, distant metastasis and death. Out of 88 patients, 23 (26.1%) patients developed locoregional recurrence and 6 (6.8%) patients developed distant metastasis. Overall survival rate was 77.3%. …

Cross-Departmental Educational Program On Complex Airway And Epistaxis Management, Adam Vasconcellos, Md, Meghan Crawley, Md, Michael Topf, Md, Ryan Gerritsen, Md, Dominick Gadaleta, Md, Joseph Spiegel, Md

House Staff Quality Improvement and Patient Safety Conference (2016-2019)

Internists, emergency medicine physicians, and intensivists routinely provide essential care for patients with complex airways (i.e. tracheostomy and laryngectomy) and patients with epistaxis. Any of these physicians may serve as first responder in a complex airway or epistaxis emergency situation. Therefore, a basic understanding of complex airway and epistaxis management is essential. The otolaryngology department aims to provide our colleagues with fundamental take-home points to improve crossdepartmental care of these patients.

Alcohol Drives Oxidation-Dependent Desensitization Of Airway Cilia Motility Responsiveness, Michael Price

Theses & Dissertations

Alcohol abuse, which can impair clearance of pathogens and debris from the airway, is associated with an increase in complications and a higher mortality rate during the progression of pneumonia. With prolonged alcohol exposure, mucociliary clearance (MCC), which depends on the coordinated beating of cilia, is dysfunctional. Effective MCC relies on cAMP-dependent protein kinase (PKA) activation of ciliary beat frequency (CBF). PKA activation and stimulation of CBF are blunted with chronic exposure to alcohol. This phenomenon is known as alcohol-induced ciliary dysfunction (AICD). Previous studies have shown that concomitant feeding of mice with alcohol and antioxidants prevents AICD, suggesting a …

Jejunal Intussusception: A Rare Manifestation Of A Primary Thyroid Non-Hodgkin Lymphoma, Abu Baker Sheikh, Usman Tariq, Marvi M. Bukhari, Sana Shah, Rao M. Afzal, Abdul Ahad E. Shaikh, Nimra Nadeem

Medical College Documents

Primary thyroid lymphoma (PTL) is an uncommon malignancy of the thyroid gland, with most lymphomas of the thyroid being almost exclusively of the non-Hodgkin's B cell variety. PTL requires a prompt diagnosis because of its ability to cause progressive compression symptoms, and its unusual presentation can make the diagnosis very challenging. Herein, we present a case of PTL in a young woman with an uncommon initial presentation and discuss the complications she faced during the surgery, as well as postoperatively, due to the compression of the trachea by the thyroid mass.

Knockout Of Pannexin-1 Induces Hearing Loss, Jin Chen, Chun Liang, Liang Zong, Yan Zhu, Hong-Bo Zhao

Otolaryngology--Head & Neck Surgery Faculty Publications

Mutations of gap junction connexin genes induce a high incidence of nonsyndromic hearing loss. Pannexin genes also encode gap junctional proteins in vertebrates. Recent studies demonstrated that Pannexin-1 (Panx1) deficiency in mice and mutation in humans are also associated with hearing loss. So far, several Panx1 knockout (KO) mouse lines were established. In general, these Panx1 KO mouse lines demonstrate consistent phenotypes in most aspects, including hearing loss. However, a recent study reported that a Panx1 KO mouse line, which was created by Genentech Inc., had no hearing loss as measured by the auditory brainstem response (ABR) threshold at low-frequency …

Unusual Presentation Of Differentiated Thyroid Cancer Metastasis, Haissan Iftikhar, Mubasher Ikram, Adnan Yar Muhammad, Karim Rizwan Nathani

Section of Otolaryngology, Head & Neck Surgery

Introduction  The rates of thyroid cancers are on a rise, especially well-differentiated thyroid cancers. This could be partly due to newer diagnostic modalities, like high-resolution ultrasound, that can pick up smaller lesions. Differentiated thyroid cancers with distant metastases are not common, and even rarer is the initial presentation with complaints not related to the neck.

Objectives  The objective of this series was to study and report the unusual cases of patients with differentiated thyroid cancer with distant metastasis. There is a lack of data in the literature on these cases, and due to the rarity of such metastases, no definite …

Frequency Of Cervical Nodal Metastasis In Early Stage Squamous Cell Carcinoma Of The Tongue, Sadaf Qadeer Ahmed, Montasir Junaid, Mohammad Sohail Awan, Maliha Kazi, Hareem Usman Khan, Sohail Haleem

Section of Otolaryngology, Head & Neck Surgery

ntroduction Oral cavity carcinoma is an aggressive tumor, with the tongue being one of the most common subsites of involvement. Surgery is a gold standard method of dealing with advanced-stage tumors. However, for early-stage carcinomas of the tongue, the management remains controversial. Several studies have indicated that early-stage cancers have a high chance of occult cervical node metastasis, which, if left untreated, can greatly affect the prognosis. Certain parameters can help identify patients with occult cervical node metastases, and can avoid unnecessary neck dissection in node negative patients. Tumor thickness is one such objective parameter. Objective To estimate the frequency …

Management Of Deep Space Infections Of The Neck, Emil Mărginean, Sargarovschi Egor, Ciprian Venter, Alina Pantiș, Oana Vălenaș, Ildiko Sorban, Maria Domuța, Cristian Bălălău, Razvan V. Scaunasu Md, Bogdan Popescu

Journal of Mind and Medical Sciences

Infections of the deep neck spaces often present a clinical challenge for the ENT surgeon. Management of these complex suppurations of the neck requires in fact a multidisciplinary approach due to possible complications like mediastinitis, septic shock and MSOF, life threatening bleeding and ICU management. The spread of infection from the primary site to other regions is possible through the lymphatic, arterial and venous vessels, or directly along the fasciae. There are several classifications for the etiology, pathogenic mechanism and site of evolution, the most frequently encountered clinical forms being peritonsillar abscess, retropharyngeal abscess, lateropharyngeal abscess, and the deep cervical …

Phosphaturic Mesenchymal Tumor Of The Nasal Cavity: Clinicopathologic Correlation Is Essential For Diagnosis, Aidan Kerr, Ryan Rimmer, Marc Rosen, James J. Evans, Madalina Tuluc, Stacey K. Mardekian

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Phosphaturic mesenchymal tumor (PMT) is a rare neoplasm in which the tumor cells produce fibroblast growth factor 23 (FGF23), leading to oncogenic osteomalacia and thus a distinct clinical presentation. However, the pathologic findings of PMT are often non-specific and variable, especially in tumors occurring in the head and neck. We present a case of a 66-year-old female who presented with osteomalacia-related symptoms and was found to have a nasal cavity mass. Histopathologic examination was suggestive of PMT but certain characteristic features were lacking, requiring confirmation of the diagnosis by chromogenic in situ hybridization (CISH) assay for FGF23 mRNA. The patient's …

Kallikrein-Related Peptidases Are Dysregulated In Pleomorphic Adenoma, Matthew D. Morrison

Electronic Thesis and Dissertation Repository

Objectives: Pleomorphic adenoma (PA) is the most common benign salivary gland tumor. Kallikrein-related peptidases (KLKs) have been identified as biomarkers in many human tumors and may influence tumor behavior. We investigated KLK1-15 messenger ribonucleic acid (mRNA) and proteins in PA specimens to determine a KLK expression profile for this tumor.

Methods: Fresh frozen PA tissue specimens (n = 26) and matched controls were subjected to RT-qPCR to detect KLK1-15 mRNA. Expression of KLK1, KLK12, KLK13 and KLK8 proteins were then evaluated via immunostaining techniques. Statistical analyses were performed with the level of significance set at P < .05.

Results: We observed downregulation …

Comparison Of New Metrics For Assessment Of Risks Of Occupational Noise, Wisam Al-Dayyeni, Jun Qin

Journal of Applied Sciences and Arts

Noise induced hearing loss (NIHL) is one of the most common occupational related health problems worldwide. Exposure to excessive noise is the major avoidable cause of permanent hearing loss. The conventional metrics for noise evaluation cannot accurately assess the exposure risks to high-level complex noise, which commonly occurs in many industrial and military fields. Recently, we have developed two advanced models, an adaptive weighting (F-weighting) and a complex velocity level (CVL) auditory fatigue model, to evaluate the risks of occupational noise. In this study, we compared performances of five noise assessment metrics, including F-weighted sound pressure level (SPL) LFeq, CVL …

Otolaryngology (ENT) Resident Research

The temporalis flap is a common flap used in head and neck reconstruction. In this article, the authors present a new modification of the use of the temporalis muscle flap for orbital skull base reconstruction with the use of a sphenoid keyhole. This technique confers multiple advantages in reducing the arc of rotation and providing a tension-free reconstruction of the orbital skull base.

International Consensus (Icon) On Treatment Of Sudden Sensorineural Hearing Loss, M. Marx, E. Younes, S. S. Chandrasekhar, J. Ito, S. Plontke, S. O'Leary, O. Sterkers

Journal Articles

© 2018 Elsevier Masson SAS Sudden sensorineural hearing loss (SSNHL) is a common and alarming symptom that often prompts an urgent visit to an ENT specialist. Treatment of SSNHL remains one of the most problematic issues for contemporary otorhinolaryngology: although many meta-analyses and national guidelines have been issued, management is not standardized in terms of medical treatment, and duration and route of administration. We present several methodological suggestions for the study of treatments for SSNHL. These were developed from the existing level of evidence of the main treatments used in SSNHL by experts who convened at the IFOS 2017 ENT …

Besides vaccinations, there are no robust measures of reducing incidence of AOM in this age-group. This is a randomized controlled clinical trial evaluating the efficacy of a non-invasive middle ear aeration device, the EarPopper device (EP). We aim to investigate the reduction of episodes AOM in children with recurrent otitis media. The control arm will be observational. The intervention arm will have the EP used. The primary endpoint is incidence of AOM. The secondary endpoints are hazard ratio of time to AOM, proportion …

Thyroseq V3 Molecular Profiling For Tailoring The Surgical Management Of Hürthle Cell Neoplasms., S. Pearlstein, A. H. Lahouti, E. Opher, Y. E. Nikiforov, D. B. Kuriloff

Journal Articles

Hürthle cell predominant thyroid nodules often confound the diagnostic utility of fine needle aspiration biopsy (FNAB) with cytology often interpreted as a Hürthle cell lesion with an indeterminate risk of malignancy, Bethesda category (BC) III or IV. Molecular diagnostics for Hürthle cell predominant nodules has also been disappointing in further defining the risk of malignancy. We present a case of a slowly enlarging nodule within a goiter initially reported as benign on FNAB, BC II but on subsequent FNAB suspicious for a Hürthle cell neoplasm, BC IV. The patient had initially requested a diagnostic lobectomy for a definitive diagnosis despite …

Isolated Inferior Rectus Muscle Entrapment Following Endoscopic Sinus Surgery, Scott Shapiro, Jamie L. Schaefer, Sumeet Gupta, John Nguyen, Brian Kellerymeyer

Faculty & Staff Scholarship

Orbital complications are known risks of endoscopic sinus surgery (ESS). The lamina papyracea and medial rectus muscle are the most commonly injured structures during ESS. Inferior rectus injury is more rare, with only one reported case of isolated inferior rectus injury in the literature. Guidelines for managing ESS-induced inferior rectus injury do not exist, and delayed intervention and management of adjacent sinuses may affect long-term outcomes such as persistent diplopia and disfigurement. In this report, we present a case of a 67-year-old man with diplopia due to isolated left inferior rectus muscle entrapment and injury from violation of the orbital …

Remarkable Presentation: Anaplastic Thyroid Carcinoma Arising From Chronic Hyperthyroidism, Habib G. Zalzal, Jeffson Chung, Jessica A. Perini

Faculty & Staff Scholarship

Background. Undifferentiated anaplastic carcinoma rarely develops from chronic hyperthyroidism. Although acute hyperthy- roidism can develop prior to anaplastic transformation, chronic hyperthyroidism was thought to be a protective measure against thyroid malignancy. Methods. A 79-year-old female presented acutely to the hospital with dyspnea. She had been taking methimazole for chronic hyperthyroidism due to toxic thyroid nodules, previously biopsied as benign. Upon admission, imaging showed tracheal compression, requiring a total thyroidectomy with tracheostomy for airway management. Results. Pathology demonstrated undifferentiated anaplastic thyroid carcinoma. The patient passed away shortly after hospital discharge. Despite treatment with methimazole for many years, abrupt enlargement of her …
