    Ultrasound tissue Doppler imaging (US-TDI) has been used to diagnose regional wall motion (WM) abnormalities in coronary artery disease but has not been applied to oropharyngeal diseases. This study aimed first to validate an US-TDI method to assess cervical esophageal (CE) WM and secondly to use the method to evaluate CE WM in patients with oropharyngeal dysphagia (OD). First, we enrolled 22 healthy men (mean age: 59.7 yr) who all underwent both US-TDI and videofluoroscopy (VF) and then esophageal high-resolution manometry (HRM) in the same week. We evaluated the reproducibility of the US-TDI and the relationship between US-TDI and other modalities (VF and HRM). Second, we enrolled 56 mild OD patients (mean age: 58.0 yr) and age- and sex-matched healthy controls. Difference in CE WM between these groups was evaluated by US-TDI. All healthy subjects underwent US-TDI, VF, and HRM successfully, with a sufficiently high reproducibility coefficient for this method, and significant correlation between US-TDI and VF/HRM parameters. US-TDI showed mean time to open CE wall and mean velocity of CE wall opening significantly differed between patients and healthy controls ( P < 0.01). In conclusion, we have developed a US-TDI method for easily assessing CE WM in daily practice and also found significant differences in CE WM between mild OD patients and healthy controls. NEW & NOTEWORTHY A new ultrasonographic screening method using tissue Doppler imaging for oropharyngeal dysphagia was found to be a reliable, reproducible, and well-tolerated method. There is a significant correlation between this new method and conventional methods. This method revealed that patients having mild symptoms of oropharyngeal dysphagia had already significantly delayed cervical esophageal wall opening.

    Background/aims: The standard of care for older patients with oropharyngeal dysphagia (OD) is poor. Stimulation of transient receptor potential vanilloid 1 might become a pharmacological strategy for these patients. This study aimed to compare the therapeutic effect of film food containing 0.

    Ability of High-Resolution Manometry to Determine Feeding Method and to Predict Aspiration Pneumonia in Patients With Dysphagia.

    Objectives: The introduction of high-resolution manometry (HRM) offered an improved method to objectively analyze the status of pharynx and esophagus. At present, HRM for patients with oropharyngeal dysphagia has been poorly studied. We aimed to determine feeding method and predict the development of aspiration pneumonia in patients with oropharyngeal dysphagia using HRM. Read More
    High-Resolution Manometry Evaluation of Pressures at the Pharyngo-upper Esophageal Area in Patients with Oropharyngeal Dysphagia Due to Vagal Paralysis.
    Dysphagia 2017 May 20. Epub 2017 May 20.
    Department of Surgery, University of North Carolina, Chapel Hill, NC, USA.
    The motility of the pharynx, upper esophageal sphincter (UES), and proximal esophagus in patients with oropharyngeal dysphagia is still not entirely understood. High-resolution manometry (HRM) was recently added to the armamentarium for the study of this area. This study aims to describe HRM findings in patients with vagal paralysis. Read More
    Usefulness of tissue Doppler echocardiography for evaluating ventricular function in children without heart disease.
    Am J Cardiol 2003 Mar;91(5):570-4
    Department of Pediatrics, University of Miami/Jackson Memorial Medical Center, Florida 33101, USA.
    Tissue Doppler echocardiographic imaging (TDI) is a novel method for accurately evaluating ventricular function. Currently, scant data are available on the distribution of tissue Doppler indexes in healthy children in the age range of 1 to 18 years. The aims of this study were to assess the distribution of tissue Doppler indexes of systolic and diastolic ventricular function in healthy children, to assess the influence of age on these indexes, and to compare them with conventional Doppler indexes.
