Organ preservation protocols of high-dose chemoradiotherapy have become fairly common to treat head and neck cancers. However, significant swallowing problems can occur. This study examines swallowing, oral tongue pressures, and tongue base-to-pharyngeal wall pressures in a patient who underwent total laryngectomy for improvement of swallowing after chemoradiotherapy for treatment of a hypophar...

Solitary angiokeratoma of oral mucosa is rare entity. The term Angiokeratoma is used to refer to several lesions, whose common denominator is the presence of dilated blood vessels in association with epidermal hyperplasia. Mucosal involvement, including oral cavity is occasionally found either as a component of the systemic variety, cutaneous involvement or isolated oral involvement. Clinically...

epitheloid hemangioendothelioma (ehe) is an uncommon angiocentric neoplasm of intermediate malignant potential. this tumor is frequently seen in the lungs and liver, but its presentation in the oral cavity is rare. in the oral cavity, gingival region is the common sites of occurrence. we report a rare case of epitheloid hemangioendothelioma in a 48-year-old male, presenting as a growth in the u...

BACKGROUND To assess non-medical university students' knowledge and perceived risk of developing oral cavity and oropharyngeal cancer. METHODS A cross-sectional survey was conducted among non-medical students of a private Midwestern university in the United States in May 2012. Questionnaire assessed demographic information and contained 21 previously validated questions regarding knowledge an...

In this article an Archimedean spiral antenna is designed and analyzed that has good operation in broadband application. By analyzing this design, the effects that different parameters have on antenna operation will be studied and ways of optimization will be found.  Influences of cavity height and number of turns to obtain good matching and gain in a frequency interval of 4 to 18 GHz will be d...

as a qHPV vaccine and Cervarix (Glaxo-SmithKline, Middlesex, UK) as a bivalent HPV (biHPV) vaccine. Both of these vaccines are effective for HPV subtypes 16 and 18, and Gardasil is effective against the two additional subtypes 6 and 11. The biHPV vaccine was approved for development in 1998, received FDA approval in 2009, and is now licensed in more than 100 countries and approved in more than ...

This term is a misnomer because the lesion is unrelated to infection and in.Pyogenic Granuloma Hyperplastic Lesion of the Gingiva: Case Reports. Like growth of the oral cavity, frequently located surrounding the anterior teeth or.Pyogenic granuloma is an inflammatory hyperplasia affecting the oral tissues. Because of the high frequency of pyogenic granuloma in the oral cavity, this.Pyogenic gra...

BACKGROUND The microbiota of the nares has been widely studied. However, relatively few studies have investigated the microbiota of the nasal cavity posterior to the nares. This distinct environment has the potential to contain a distinct microbiota and play an important role in health. RESULTS We obtained 35,142 high-quality bacterial 16S rRNA-encoding gene sequence reads from the nasal cavi...

This paper presents a numerical investigation of the laminar mixed convection flow of a radiating gas in an inclined lid-driven cavity. The fluid is treated as a gray, absorbing, emitting, and scattering medium. The governing differential equations including continuity, momentum and energy are solved numerically by the computational fluid dynamics techniques (CFD) to obtain the velocity and tem...
