Background: The Bethesda System for Reporting Thyroid Cytopathology is the standard for interpreting fine needle aspiration (FNA) specimens. The atypia of undetermined significance/follicular lesion of undetermined significance (AUS/FLUS) category, known as Bethesda Category III, has been ascribed a malignancy risk of 5-15%, but the probability of malignancy in AUS/FLUS specimens remains unclear. Our objective was to determine the risk of malignancy in thyroid FNAs categorized as AUS/FLUS at a comprehensive cancer center. Methods: The management of 541 AUS/FLUS thyroid nodule patients treated at Memorial Sloan-Kettering Cancer Center between 2008 and 2011 was analyzed. Clinical and radiologic features were examined as …

Journal Articles

BACKGROUND: The purpose of this study was to report the long-term outcome of patients with squamous cell cancer (SCC) of the tonsil managed by surgery followed by postoperative radiotherapy (PORT). METHODS: Eighty-eight patients treated between 1985 and 2005 were analyzed. Overall survival (OS), disease-specific survival (DSS), and recurrence-free survival (RFS) were determined by the Kaplan-Meier method. Factors predictive of outcome were determined by univariate and multivariate analysis. RESULTS: Forty-eight percent of patients had T3 to T4 disease and 75% had a positive neck. Five-year OS, DSS, and RFS were 66%, 82%, and 80%, respectively. The status of the neck was …

Cochlear Development And Auditory Function In The Absence Of Thyroid Hormone Transporters Mct8 And Oatp1c1, Richard Sinn

All Graduate Theses, Dissertations, and Other Capstone Projects

Thyroid hormone (TH) is essential for the development and maturation of the nervous system. The thyroid gland secretes an active form of TH, triiodothyronine, and a prohormone, thyroxine, into the blood. TH is charged, which prevents it from passively diffusing across cell membranes and thus requires cell membrane transporters to facilitate its movement into and out of cells. However, whether TH transporters are required for TH-mediated developmental events, including the auditory system, is largely unknown.

The purpose of the present study was to investigate two specific TH transporters, monocarboxylate transporter 8 (Mct8) and organic anion transporting polypeptide 1c1 (Oatp1c1), and …

Department of Otolaryngology - Head and Neck Surgery Faculty Papers

OBJECTIVE: To examine the sinus-related sequelae of free flap reconstruction for complex orbitofacial defects.

STUDY DESIGN: Retrospective chart review METHODS: Demographic, clinical, and radiographic data on a series of 55 patients who had undergone free tissue transfer for orbitofacial reconstruction was retrospectively reviewed. Follow-up of ≥ 3 months was available for 49 patients. Outcome measures studied included clinical or radiographic evidence of sinusitis and the need for sinus surgery.

RESULTS: The most commonly involved sinuses were the ethmoid (n=40) and maxillary (n=38) sinuses, and the anterolateral thigh was the most common flap used (n=41). Clinical and/or radiographic sinusitis was evident …

Noise-Induced Tinnitus Using Individualized Gap Detection Analysis And Its Relationship With Hyperacusis, Anxiety, And Spatial Cognition, Edward Pace, Jinsheng Zhang

Communication Sciences and Disorders Faculty Research Publications

Tinnitus has a complex etiology that involves auditory and non-auditory factors and may be accompanied by hyperacusis, anxiety and cognitive changes. Thus far, investigations of the interrelationship between tinnitus and auditory and non-auditory impairment have yielded conflicting results. To further address this issue, we noise exposed rats and assessed them for tinnitus using a gap detection behavioral paradigm combined with statistically-driven analysis to diagnose tinnitus in individual rats. We also tested rats for hearing detection, responsivity, and loss using prepulse inhibition and auditory brainstem response, and for spatial cognition and anxiety using Morris water maze and elevated plus maze. We …

Section of Otolaryngology, Head & Neck Surgery

Objectives: To assess the diagnostic value of sentinel lymph node localisation using pre-operative lymphoscintigraphy and intra-operative gamma probe radio localisation in Pakistani patients suffering from early stage squamous cell carcinoma of the oral cavity.
Methods: The prospective case series was conducted between September 2007 and April 2010 at the Aga Khan University Hospital, Karachi. It comprised patients with T1and T2 oral cavity cancer with clinically and radiologically negative neck. Pre-operative lymphoscintigraphy was performed one day before surgery and intra-operative gamma probe was used to detect sentinel node. Final histo-pathological evaluation was taken as the gold standard.
Results: The study comprised …

Marine-Lenhart Harboring Papillary Thyroid Cancer, Brian Y. Chou, Md, Sharon Segal, Do, Edmund A. Pribitkin, Md, Jeffery L. Miller, Md

Department of Otolaryngology - Head and Neck Surgery Presentations and Grand Rounds

Introduction

Graves' disease with functioning nodules is referred to as Marine-Lenhart Syndrome. Only 2.7% of the patients with Graves’disease have concomitant functioning nodules.¹ Thyroid scintigraphy often definitively confirms the diagnosis. However, in addition to a hyperfunctioning (i.e. "hot") nodule, the thyroid scan may reveal isofunctioning (i.e. "warm"), and or a nonfuntioning (i.e. "cold") nodule as compared to the normal surrounding thyroid. Since hyperfuntioning nodules rarely harbor malignancy, if one is found that corresponds to the nodule in question, no cytologic evaluation is usually necessary.² Conversely, the majority of all nonfunctioning nodules may be benign or less frequently malignant, …

Cochlear Implant In A Patient With Mondini's Deformity Of The Cochlea: Pilot Patient In Pakistan, Sadaf Qadeer Ahmed, Montasir Junaid, Zainul Abedeen Sobani, N Naila, Mohammad Sohail Awan

Department of Surgery Docs

Abstract

Autosomal-recessive genes account for about 80% of the patients of non-syndromic deafness, and a major portion of those lead to cochlear pathology. Given the strong cultural practice of consanguineous marriages and the lack of awareness regarding screening modalities, a high prevalence of hereditary pre-lingual deafness is seen in Pakistan. Considering the situation, cochlear implant surgery was introduced by Aga Khan University Hospital (AKUH), Karachi, Pakistan, in 2003. Recently we decided to expand the profile and services available and conducted the first ever cochlear implant on an anatomically-challenged cochlea. The case report relates to the experience of our pilot patient …

Section of Otolaryngology, Head & Neck Surgery

Managing penetrating injuries adequately and effectively depends a great deal on proper assessment of the injury. This study carried out was done at The Aga Khan University Hospital to assess the role of clinical examination and CT scan imaging in evaluation of penetrating neck injuries. A total of 68 students were included, with ages ranging from 3 to 74 years. The involved zones and the injured structures were noted. Results showed a high sensitivity of clinical examination in assessing vascular (81%) and airway trauma (77%), with a low sensitivity for esophageal trauma (34%). For CT scan the sensitivity was 90% …

A 37-year-old woman presented with a history of visual loss and painful protrusion of the right eye for the preceding 3 days.This was accompanied by vertigo and right-side facial weakness. The patient had perception of light in her right eye and 20/25 (presenting visual acuity) in the fellow eye, accompanied by right-side proptosis, total ophthalmoplegia, optic disc pallor and central retinal artery occlusion. Magnetic resonance imaging showed the presence of oedema with soft-tissue …

Endoscopic Ultrasonic Dacryocystorhinostomy For Recurrent Dacryocystitis Following Rhinoplasty, Nadia Mostovych, Md, Mindy R. Rabinowitz, Md, Edmund A. Pribitkin, Md, Jurij R. Bilyk, Md

Department of Otolaryngology - Head and Neck Surgery Presentations and Grand Rounds

Abstract:

The lacrimal sac is the structure most vulnerable to injury when performing osteotomies for rhinoplasty. When performed in a low lateral position or along the frontal process of the frontal-maxillary suture, osteotomies have the potential to tear the medial canthal ligament and injure the underlying lacrimal sac resulting in dacryocystitis. We report a case of dacryocystitis in a 19 year old male who presented with recurrent episodes of pain, tearing, and discharge from his left eye following primary rhinoplasty. He was found to have obstruction of the lacrimal system secondary to a low lateral osteotomy with an impinging bone …
