BACKGROUND Human papillomavirus (HPV) infection is a powerful prognostic biomarker in a subset of head and neck squamous cell carcinomas, specifically oropharyngeal cancers. However, the role of HPV in non-oropharyngeal sites, such as the larynx, remains unconfirmed. METHODS We evaluated a cohort of 324 laryngeal squamous cell carcinoma (LSCC) patients(More)
BACKGROUND The role of fine-needle aspiration (FNA) in salivary gland lesions as a preoperative diagnosis has always been under scrutiny. Several studies have shown that frozen section (FS) is accurate for pathological diagnosis and decision-making during the surgery. This study has been carried out to assess the accuracy of FNA and FS in parotid surgeries.(More)
OBJECTIVE To determine (1) the prevalence and nature of connexin 26 mutations in a cohort of Australian children with non-syndromic hearing loss, and (2) the carrier frequency of the common connexin 26 mutation (35delG) in the general population. DESIGN A cohort, case-finding study. Mutation analysis was performed on DNA extracted from white blood cells,(More)
RATIONALE Upper airway dysfunction may complicate asthma but has been largely ignored as an etiological factor. Diagnosis using endoscopic evaluation of vocal cord function is difficult to quantify, with limited clinical application. OBJECTIVES A novel imaging technique, dynamic 320-slice computerized tomography (CT), was used to examine laryngeal(More)
INTRODUCTION The objective of this paper was to review the results of primary non-surgical treatment with the aim of larynx preservation for loco-regionally advanced larynx cancer (LALC). METHODS All patients with LALC presenting between January 2002 and December 2006 who were selected for primary non-surgical treatment were included in this study. (More)
OBJECTIVES Most voice self-rating tools are disease-specific measures and are not suitable for use with healthy voice users. There is a need for a tool that is sensitive to the subtleties of a singer's voice and to perceived physical changes in the singing voice mechanism as a function of load. The aim of this study was to devise and validate a scale to(More)
Music theater singers (MTS) typically have a heavy vocal load, but the impact on their voices has not been previously evaluated. A group of 49 MTS from two professional productions were administered the Singing Voice Handicap Index (SVHI). Responses for the SVHI demonstrated that, although the SVHI supported the performers' self-report of healthy vocal(More)
OBJECTIVE a) To report on an adult patient with congenital long-segment tracheal stenosis from complete tracheal rings complicated by tracheomalacia; b) to highlight the fact that some patients with airway narrowing could be misdiagnosed as having bronchial asthma; and c) to discuss our management with a custom-made tracheostomy tube extending to the(More)
OVERVIEW Working music theater singers (MTS) typically have a heavy vocal load and little is known about their perception of vocal function. The Evaluation of the Ability to Sing Easily (EASE) was used to assess professional MTS' perceptions of current singing voice status and to compare scores across demographic and performance characteristics and to(More)
