We present Swallow, a scalable many-core architecture, with a current configuration of 480 × 32-bit processors. Swallow is an open-source architecture, designed from the ground up to deliver scalable increases in usable computational power to allow experimentation with many-core applications and the operating systems that support them. Scalability is enabled by the creation of a tile-able syste...

The oropharyngeal swallow mechanism is comprised of several behaviours that change systematically or occur randomly. The systematic changes are dependent on the bolus characteristics (i.e. volume and viscosity) and voluntary control. An oropharyngeal swallow is rapid (less than 2 s), and videofluoroscopy is required to determine which muscles or nerves are damaged in dysphagic patients. Once th...

Buggy Creek (BCR) virus is an arthropod-borne alphavirus that is naturally transmitted to its vertebrate host the cliff swallow (Petrochelidon pyrrhonota) by an invertebrate vector, namely the cimicid swallow bug (Oeciacus vicarius). We examined how the prevalence of the virus varied with the group size of both its vector and host. The study was conducted in southwestern Nebraska where cliff sw...

A 3-year-old girl had multiple anomalies compatible with Treacher Collins Syndrome (TCS). From the neonatal period, sucking was poor, making tube feeding necessary. Excessive saliva was retained in the oral cavity. Nasal leakage caused by the cleft palate was observed when she spoke. The initial videofluoroscopic swallow study (VFSS) showed a poor posterior bolus transit and nasopharyngeal regu...

The patient, aged 20, was admitted into the hospital on 2nd December, 1943, with a history of dysphagia for 15 months. To begin with, he could swallow semisolids and fluids but later he could swallow fluids only, and at times even this was impossible. There was no history of syphilis, and physical examination revealed no obvious cause of the condition. X-ray examination after a barium swallow r...

BACKGROUND This study investigated the effects of 2 different swallowing exercise regimens performed during radiation therapy with/without chemotherapy on swallowing function. METHODS Fifty patients were recruited prospectively to 2 groups (the exercise group, n = 26 and the repetitive swallow group, n = 24). Functional Oral Intake Scale (FOIS) scores and percutaneous endoscopic gastrostomy (...

BACKGROUND Fever, hyperglycemia, and swallow dysfunction poststroke are associated with significantly worse outcomes. We report treatment and monitoring practices for these three items from a cohort of acute stroke patients prior to randomization in the Quality in Acute Stroke Care trial. METHOD Retrospective medical record audits were undertaken for prospective patients from 19 stroke units....

BACKGROUND Previous investigators have found permanent changes in saliva production after chemoradiation but have not examined these in relation to swallowing measures, diet changes, and patient comfort over time. METHODS Thirty patients with advanced stage cancer of the oropharynx treated with chemoradiation were followed with videofluoroscopic swallow studies, a measure of stimulated total ...

BACKGROUND Total or near-total glossectomy defects are commonly reconstructed with rectus abdominis myocutaneous flaps for coverage. Sensory reinnervation has rarely been performed. METHODS Thirteen consecutive total or near-total glossectomy reconstructions were performed in a 12-month period with anterolateral thigh flaps with (n = 8) or without (n = 5) sensory reinnervation to the lingual ...

Swallow or deglutition syncope is a relatively rare syndrome. It is a vagally mediated syncope induced by swallowing. Swallow syncope may occur in all age groups and, when diagnosed, is treatable. A woman, aged 60 years, presented with an episode of a syncopal attack associated with swallowing a sandwich. She had a 6-month history of recurrent episodes of lightheadedness while eating solid food...
