[Process of swallowing disturbance in XXXX --evaluation of videofluorography and respiratory function].

@entity1 @entity1282 @entity746
We investigated the process of swallowing disturbance in the @entity1 with @entity746 ( @entity746 ). Swallowing function of 11 @entity1 with @entity746 (67.5 +/- 7.5 y.o.) was evaluated by videofluorography (VF) and swallowing part of @entity746 functional rating scale (FRSsw) more than 2 times during the course. Percent of forced vital capacity (%FVC) was also measured. VF measures were oral leakage, poor bolus formation, retention in oral cavity, abnormal transport to pharynx as oral stage and delayed swallowing reflex, laryngeal penetration, aspiration, nasal regurgitation, retention in valleculae and pyriform, and abnormal opening of pharyngo-esophageal segment as pharyngeal stage. FRSsw were defined as 4: normal eating habits, 3: early eating problems--occasional choking 2: dietary consistency changes, 1: needs supplemental tube feeding and 0:NPO (exclusively parental or enteral feeding). According to VF findings in the course of oral stage and pharyngeal stage, in some @entity1 , the disturbance of oral stage preceded that of pharyngeal stage, while in the other @entity1 , the disturbance of pharyngeal stage disturbance preceded that of oral stage, and in another @entity1 were mixed course. There was poor relationship between the FRSsw and VF measure. Even in the @entity1 of FRSsw 4 _ 3. penetration/aspiration were found. %FVC was 70.0 +/- 17.3% in @entity1 with FRSsw 4 _ 3, 43.1 +/- 17.6% in @entity1 with FRSsw 2 and 40.4 +/- 16.2% in @entity1 with FRS 1 _ 0. In the individual course, FRSsw decreased in parallel with %FVC. We conclude that there are various course of swallowing disturbance on VF findings, the oral stage disturbance proceed, the pharyngeal stage disturbance proceed or mixed. Swallowing function deteriorate in parallel with respiratory function in @entity746 @entity1 . We have to take measures against the @entity1282 even in early stage.
