    Preliminary observations on the effects of age on oropharyngeal deglutition (1989)

    Notizen: Abstract Swallows of 4 bolus volumes (1, 5, 10, 20 ml) were examined in three groups of subjects: 6 subjects 20–29 years of age, 12 subjects 30–59 years of age, and 6 subjects 60–79 years of age. A simultaneous manometric and videofluoroscopic data collection protocol permitted measurement of bolus transit, temporal aspects of the oropharyngeal swallow, and pharyngeal peristalsis. Statistically significant effects of increasing bolus volume were oral transit of the bolus head (decreased) and duration of cricopharyngeal opening (increased). Five measures were significantly changed with increasing age: duration of pharyngeal swallow delay (increased), duration of pharyngeal swallow response (decreased), duration of cricopharyngeal opening (decreased), peristaltic amplitude (decreased), and peristaltic velocity (decreased).

    Effects of intraoral prosthetics on swallowing in patients with oral cancer (1989)
    Springer
    Dysphagia 4 (1989), S. 118-120

    ISSN: 1432-0460
    Schlagwort(e): Intraoral prosthesis ; Oral cancer
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Medizin
    Notizen: Abstract The swallowing patterns of four patients with oral cancer with intraoral palate reshaping/lowering prostheses were studied with and without their prostheses 3 months postoperatively. The prostheses resulted in improved swallow efficiency, increased duration of tongue contact to the pharyngeal wall, and improved speed of movement of the bolus from the valleculae to the pyriform sinus. These results emphasize the effects of the tongue on the pharyngeal as well as oral stage of the swallow.

    Volume accommodation during swallowing (1993)
    Springer

    Notizen: Abstract Bolus volume is an important modifier of the biomechanical events of the oropharyngeal swallow. The biomechanical events comprising a swallow can be divided into events associated with the reconfiguration of the pharynx into a swallow pathway and events associated with bolus transport from the oropharynx into the esophagus. Volume modification is achieved differently for the events of reconfiguration and propulsion. In the case of reconfiguration, a longer time is allocated to the process, as exemplified by sustained laryngeal elevation and hyoid excursion during larger volume swallows. On the other hand, in the case of bolus expulsion, volume accommodation is accomplished within the same period of time by utilizing increased vigor of expulsion. The result of deglutitive volume accommodation is a remarkably different fluoroscopic appearance of a small vs. a large volume swallow. The larger volume swallow seemingly takes longer and results in much more vigorous bolus expulsion than a small volume. However, this is more related to the bolus than the swallow.

    Considerations about pharyngeal manometry (1987)
    Springer
    Dysphagia 1 (1987), S. 209-214

    ISSN: 1432-0460

    Thema: Medizin
    Notizen: Abstract Intraluminal manometry has the potential to provide relevant information for clinical or research studies of pharyngeal motor function. The usefulness of this information, however, depends on appropriate manometric instrumentation and technique. In this report, we discuss the instrumentation and techniques that are currently available for meaningful acquisition and interpretation of pharyngeal pressure phenomena.

    Oropharyngeal swallowing after stroke in the left basal ganglion/internal capsule (1993)
    Springer
    Dysphagia 8 (1993), S. 230-234 
    Details
    ISSN: 1432-0460

    Thema: Medizin
    Notizen: Abstract One of the foci of Martin Donner's work was the neural control of swallowing. This present investigation continues that work by examining oropharyngeal swallowing in 8 patients identified with a single, small, left-basal ganglion/internal capsule infarction and 8 age-matched normal subjects. Stroke patients were assessed with a bedside clinical and radiographic swallowing assessment, and normal subjects received only the radiographic study. Results revealed disagreement between the bedside and radiographic assessments in one of the 8 stroke patients. Stroke and normal subjects differed significantly on some swallow measures on various bolus viscosities, but behaved the same as normal subjects on a number of measures. Differences in swallowing in the stroke subjects were not enough to prevent them from eating orally. The significant differences seen in the basal ganglia/intemal capsule stroke subjects may result from damage to the sensorimotor pathways between the cortex and brainstem. These differences emphasize the importance of cortical input to the brainstem swallowing center in maintaining the systematic modulations characteristic of normal swallowing physiology.

    Effect of cisapride, a new prokinetic agent, on esophageal motor function (1987)
    Springer
    Digestive diseases and sciences 32 (1987), S. 1331-1336

    ISSN: 1573-2568
    Schlagwort(e): cisapride ; lower esophageal sphincter ; esophageal motor function

    Thema: Medizin
    Notizen: Abstract In this study, we assessed by a double-blinded, cross-over design the effect of intravenous and oral cisapride on esophageal motor activity during the late fed state in normal subjects. For the intravenous study, subjects were given placebo or 10 mg cisapride randomly, while in the oral study, they randomly received placebo or cisapride at 5, 10, or 20 mg. Cisapride given intravenously or orally caused a significant increase in resting LES pressure. The increase in LES pressure after oral administration was significant only after the 20 mg dose. Esophageal-body peristaltic amplitude, determined for all smooth-muscle sites, showed a modest but significant increase of approximately 10 mm Hg after intravenous cisapride, whereas no significant increase occurred after oral cisapride. Propagation time of peristalsis was unaffected by intravenous or oral cisapride. Side effects of treatment were minimal and at no time necessitated cessation of the study. We conclude that in healthy subjects during the late fed period, (1) cisapride at 10 mg intravenously or 20 mg orally increased resting LES pressure and (2) at 10 mg intravenously, but at no oral dose, cisapride increased peristaltic amplitude without affecting propagation time. The potentiating effect of cisapride on LES pressure suggests that cisapride could have an ancillary role in the therapy of gastroesophageal reflux disease.
