Purpose: The characteristic changes in the swallowing mechanism with aging are collectively termed presbyphagia. Although several studies have investigated presbyphagia in older adults, few have assessed oldest-old adults. We aimed to characterize the latent changes of swallowing function in oldest-old adults and to consider risk ages for presbyphagia.

Germline pathogenic ETV6 variants have been discovered in families with inherited thrombocytopenia and predisposition to hematological and solid malignancies. We present a patient with short stature who was initially diagnosed with chronic immune thrombocytopenia. Subsequently, the patient developed acute lymphoblastic leukemia, followed by mammary analog secretory carcinoma.

Objective: Mano-videoendoscopy (MVE) is a manometry technique with endoscopic confirmation of the pressure catheter. This study aimed to investigate the possibility of replacing a videofluorographic swallowing study (VFSS) with MVE for the precise evaluation of the pharyngeal contraction and the upper esophageal sphincter (UES) function.

Methods: The data from 69 patients with dysphagia were retrospectively reviewed.

Conclusions: Mano-videoendoscopy (MVE), a manometry technique with endoscopic confirmation of the pressure catheter, can supplement the information on upper esophageal sphincter (UES) function, and overcomes the drawbacks of videoendoscopic swallowing study (VESS).

Objectives: This study aimed to investigate the possibility of replacing videofluorographic swallowing study (VFSS) with MVE, as a test to precisely evaluate UES function.

Methods: Data from 52 patients with dysphagia were retrospectively reviewed.

Article Synopsis
  • Cisplatin plus fluorouracil is commonly used to treat head and neck cancer but requires hospitalization, prompting the development of an outpatient regimen involving S-1 and nedaplatin.
  • In a phase I study, 14 patients received oral S-1 for 14 days and increasing doses of intravenous nedaplatin, with the maximum tolerated dose found to be 90 mg/m², primarily causing neutropenia and thrombocytopenia.
  • The recommended nedaplatin dose for further studies was established at 80 mg/m², as the new regimen showed good tolerance and a response rate of 57.1%.

Some diseases in which persons show vertigo or dizziness may be life-threatening, regardless of symptom severity, and require careful attention. These include diseases of the inner ear, central nervous system, and cardiovascular manifestation. In May 2006, a group in charge of primary emergency consultation began work enabling physicians to treat vertigo patients more efficiently and safely, as detailed in this report.

Article Synopsis
  • Preservation of the larynx is crucial for the quality of life in head and neck cancer treatment, specifically focusing on preserving laryngeal function through chemoradiotherapy.
  • The study examined 32 patients with resectable squamous cell carcinoma, using a combination of induction chemotherapy and chemoradiotherapy, which included cisplatin, 5-fluorouracil, and weekly nedaplatin and docetaxel.
  • Results showed that 21 out of 29 patients successfully preserved their laryngeal function, achieving an initial preservation rate of 93.8%, highlighting a promising approach for treating advanced laryngeal and hypopharyngeal cancer.

Conclusions: Videofluoroscopy (VF) in the prone position can diagnose a range of esophageal pathologies in all age groups. These correlate with globus sensation in younger and middle-aged patients in prone and supine positions. Abnormal esophageal clearance appears to be associated with globus sensation in young and middle-aged persons, but not in the elderly.

Tracheostomy placement affects swallowing function, increasing the risk of aspiration. Recent studies suggest that because of increased risk of swallowing disturbance associated with tracheostomy, one-way speaking valve placement may help to reduce aspiration in tracheostomized patients. We hypothesize that airflow exhaled through the laryngeal cavity using the one-way speaking valve may improve the clearance of residual bolus from the upper airway, thus preventing bolus penetration and aspiration.
