BACKGROUND Oral and pharyngeal cancer is a serious health threat that goes unnoticed by most people. Increasing screenings for oral and pharyngeal cancer is essential to achieving early detection when the disease is most treatable. PURPOSE We tested the effectiveness of a media campaign designed to increase intentions to seek an oral and pharyngeal cancer screening. We further examined whethe...

The Caenorhabditis elegans pharynx (or foregut) functions as a pump that draws in food (bacteria) from the environment. While the "organ identity factor" PHA-4 is critical for formation of the C. elegans pharynx as a whole, little is known about the specification of distinct cell types within the pharynx. Here, we use a combination of bioinformatics, molecular biology, and genetics to identify ...

BACKGROUND Mandibular advancement surgery may positively affect pharyngeal airways and therefore potentially beneficial to obstructive sleep apnea (OSA). OBJECTIVE To collect evidence from published systematic reviews that have evaluated pharyngeal airway changes related to mandibular advancement with or without maxillary procedures. METHODOLOGY PubMed, EMBASE, Web of Science, and Cochrane ...

The impressive morphological diversification of vertebrates was achieved in part by innovation and modification of the pharyngeal skeleton. Extensive fate mapping in amniote models has revealed a primarily cranial neural crest derivation of the pharyngeal skeleton. Although comparable fate maps of amphibians produced over several decades have failed to document a neural crest derivation of vent...

introdouction: the aim of this study was to compare information regarding pharyngeal airway sizes in adolescent subjects with different malocclusion classes obtained from lateral cephalograms and 3–dimensional (3d) cone-beam computed tomography (cbct) scans. materials and methods: in this prospective cross-sectional study, cbct scans and lateral cephalograms of 35 subjects, taken within one wee...

Background: Pharyngeal infections with gonorrhea (GC) and chlamydia (CT) can be missed if screened only by routine methods of urethral or urine specimens and may increase the risk of sexually transmitted infections and HIV acquisition and transmission. The prevalence of pharyngeal GC and CT in men who have sex with men (MSM) has been reported as 5.3-9.2% and 1.4-1.9% respectively. The objective...

The aim of the study was to analyse the disturbances of the oro-pharyngeal swallowing phase of dysphagia in amyotrophic lateral sclerosis (ALS) patients with the use of specific manometric measurements and to evaluate their plausible association with the duration of the disease. Seventeen patients with ALS were evaluated with manometric examinations of the oral and pharyngeal part of the gastro...

bstructive sleep apnea is a common disorder with imporant sequelae. Aging substantially increases the risk of bstructive apnea, although the mechanisms underlying his predisposition remain unclear. Most current evience suggests that obstructive apnea results from an interction of the anatomy of the upper airway with the control f pharyngeal dilator muscles. Afflicted patients have comromised ph...

The relative impact of mechanical factors on pharyngeal patency in patients with obstructive sleep apnea is poorly understood. The present study was designed to evaluate parameters of the "tube law" on pharyngeal pressure-flow relationships and collapsibility in patients with obstructive sleep apnea. We developed a mathematical model that considered the collapsible segment of the pharynx to rep...
