Objectives: This study aimed to estimate vocal loading in loud phonation of a vowel and two widely used semiocclusion voice exercises (SOVTEs). Impact stress (IS) was estimated from glottal closing speed, inertial forces from the second derivative of glottal opening and closing.

Study Design: Experimental study in vivo.

Article Synopsis
  • - This study explores the use of a GAGLESS mouthpiece in esophagogastroduodenoscopy (EGD) as a way to improve comfort and ease during the endoscopic procedure for gastric cancer screening.
  • - Conducted on 101 male patients, the research found that transnasal endoscopy with the GAGLESS mouthpiece resulted in significantly lower pain scores compared to peroral endoscopy, although both methods provided similar levels of discomfort during anesthesia.
  • - The findings suggest that the GAGLESS mouthpiece may be particularly beneficial for patients struggling with nasal endoscope insertion, as it can help reduce discomfort while enhancing gastric visibility.

Uncapped Metered-Dose Inhalers: A Risk for Foreign Body Aspiration. A Case Report and Review of the Literature.

Department of Infectious Diseases, Respiratory Medicine and Critical Care, Charité - Universitätsmedizin Berlin, Corporate Member of Freie Universität Berlin, Humboldt-Universität zu Berlin, Berlin Institute of Health, Berlin, 10117, Germany.

The risk of foreign body aspiration associated with uncapped handheld metered-dose inhalers (MDIs) is underestimated. We report a case in which a plastic cable clip accidentally lodged in the mouthpiece of an uncapped pressurized MDI was aspirated during its use. A literature search revealed 16 other cases of foreign body aspiration associated with uncapped handheld inhalers, all but one of which were pressurized inhalers.

Objectives: The whole picture of the disturbance in endoscopy performance caused by the coronavirus disease 2019 (COVID-19) pandemic in Japan remains to be clarified. Therefore, the Japan Gastroenterological Endoscopy Society-Tohoku conducted this questionnaire survey in Tohoku region of Japan.

Methods: A questionnaire on the number of diagnostic endoscopy procedures and resulting diagnosed cancers in 2019 and 2020 was sent to all guidance/guidance cooperation hospitals in the Japan Gastroenterological Endoscopy Society who worked in the Tohoku region.

Purpose: Coughing is related to voice problems, since it involves firm glottal closure, fast glottal opening, and high subglottic pressure and flow rate. In this study, the glottal area variation and movements of laryngeal structures during coughing and phonation are compared.

Methods: High-speed laryngoscopy recordings were made of a normophonic male participant with a healthy larynx producing a neutral vowel and coughing.
