ABSTRACT
Swallowing disorders resulting from pseudobulbar palsy are characterized by deficiencies in the oral preparatory and oral stages of the swallowing process. In certain cases, obstruction can occur when the tongue base comes into contact with the palate, impeding the intraoral bolus flow into the pharyngeal cavity. In this report, we discuss a case of severe pseudobulbar palsy, in which an intraoral bolus flowed into the pharyngeal cavity with pinching the nose. A 78-year-old man with a history of recurrent cerebral infarction was evaluated. The patient had severe dysphagia and cognitive impairment due to pseudobulbar palsy. A videofluoroscopic examination of swallowing (VF) was conducted while the patient was in a reclined position. In the oral cavity, when the bolus reached the posterior tongue section, the flow was hindered by the functional obstruction caused by the tongue base pressing against the palate. Despite the clinician's instructions to swallow, the patient was unable to comply due to the severity of his cognitive impairment. To alleviate this obstruction, the clinician pinched the patient's nose. This action opened the fauces, facilitating breathing and relieving the functional obstruction. Subsequently, the bolus flowed into the pharyngeal cavity and successfully flowed into the esophagus while swallowing. This maneuver was named the "pinching nose maneuver" (PNM). The PNM, as described here, can serve as a technique to improve the movement of an intraoral bolus into the pharyngeal cavity in patients with cognitive dysfunction.
ABSTRACT
BACKGROUND: Improvement of the completion rate of postoperative adjuvant chemotherapy is a key to obtaining favorable prognosis in patients who undergo macroscopically curative pancreatectomy for pancreatic ductal adenocarcinoma. STUDY DESIGN: This study is a prospective single-center phase II trial that aimed to examine whether a supervised exercise therapy for pancreatic ductal adenocarcinoma improved the completion rate of S-1 adjuvant chemotherapy in the development of a tolerable and effective exercise plan for patients undergoing adjuvant therapy. RESULTS: Forty-three patients were included in the study. The completion rate of S-1 therapy, the primary endpoint, was 93%, which exceeded the threshold completion rate of 53% (p < 0.001). As secondary endpoints, the relative dose intensity of S-1 was 100.0 [95.9 to 100.0] (median [interquartile range]), the median recurrence-free survival was 20.4 months, and the median overall survival was not reached, confirming the safety of the protocol treatment. Regarding frailty status, there was significant decrease in the Kihon checklist score (p = 0.002) and significant increase in G8 questionnaire score (p < 0.001), indicating that exercise therapy reduced frailty. There were no incidences of serious adverse events except for 1 case of grade 3 febrile neutropenia. The differences between before/after therapy (between 6 months/baseline) of mean muscle mass, mean body fat mass, mean body fat percentage, and mean controlling nutrition status score were 1.52 (p < 0.001), -1.18 (p = 0.007), -2.47 (p < 0.001), and -0.59 (p = 0.006), respectively. CONCLUSIONS: Adjuvant chemotherapy combined with supervised exercise therapy for pancreatic ductal adenocarcinoma was confirmed to improve the completion rate of S-1 adjuvant chemotherapy.
