The novel conceptual disease model, the oral-gut axis, which represents the immunomodulatory mutual relationship between oral and gut microbial compartments, has been attracting attention in relation to systemic health issues. We investigated whether this unique crosstalk influences the systemic condition of patients with COVID-19 infections who received extracorporeal membrane oxygenation (ECMO) in the intensive care unit (ICU) during April and December 2020. In this case-control study, patients were divided into two groups according to their survival (total entry size, = 21; survivors, 13; non-survivors, 8).

Primary oral diffuse large B cell lymphoma (DLBCL) is rare and the differential diagnosis is difficult due to its low incidence and nonspecific symptoms, which resemble those of common oral diseases in the initial clinical setting. We aimed to discuss the value of making an accurate diagnosis using liquid-based cytology (LBC) and cell block (CB) for not only the morphological interpretation but also cytohistological assessment of oral DLBCL. LBC and CBs made from oral brushing materials were prepared on the first medical examination and a morphological analysis and immunohistochemical analysis of specific biomarkers were performed.

Objectives: The number of elderly patients with systemic basal disease requiring invasive dental treatment has increased. Appropriate prediction of surgical invasiveness and combined use of psychosedation are thought to contribute to safe whole-body management. Dexmedetomidine (DEX) exhibits analgesic and anti-anxiolytic properties and causes mild respiratory depression.

QT prolongation is an electrocardiographic change that can lead to lethal arrhythmia. Acquired QT prolongation is known to be caused by drugs and electrolyte abnormalities. We report three cases in which the prolonged QT interval was improved at the time of operation by briefly discontinuing the drugs suspected to have caused the QT prolongation observed on preoperative electrocardiography.

Background: It is important to evaluate preoperative anxiety and prepare sedation when performing dental surgery under local anesthesia. Spielberger's State-Trait Anxiety Inventory (STAI) is useful for predicting preoperative anxiety. State anxiety is defined as a subjective feeling of nervousness.

We report a case of a morbidly obese man with an aortic aneurysm, in whom dental surgery was performed before elective cardiac surgery. His aortic aneurysm required emergency surgery. However, because of his morbid obesity, elective cardiac surgery was planned.

The purpose of this study was to determine the relationship between the head position and the subsequent ease of nasotracheal intubation by using the lightwand device Trachlight (TL). Patients requiring nasotracheal intubation were subdivided into 3 groups according to the intubated head position (group S: sniffing position; group E: extension position; and group N: neutral position). The number of attempts, the total intubation time, and the failures of the TL intubation were recorded.

Moyamoya disease is a rare neurovascular disorder that involves constriction of certain arteries in the brain. In patients with moyamoya disease, it is very important to prevent cerebral ischemic attacks and intracerebral bleeding caused by fluctuating blood pressure and increased respiration. A 40-year-old woman with moyamoya disease was scheduled for extraction of her right upper and lower impacted wisdom teeth.

Purpose: The purpose of this study was to evaluate the usefulness of Trachlight (TL) for nasotracheal intubation and to determine the relationship between the grade of laryngeal view and the subsequent ease of nasotracheal intubation using TL.

Methods: Patients requiring nasotracheal intubation were enrolled in this study. Laryngoscopy was performed in all patients under topical anesthesia, with 8% lidocaine spray applied to the supraglottic region and the vocal cords.

Purpose: The aim of this study was to assess by means of power spectral analysis the immediate response of autonomic regulation that occurs with postural change from supine to sitting position (modified head-up tilt test [m-HUT]) during autologous blood donation (ABD) and postphlebotomy infusion.

Patients And Methods: We investigated 37 healthy adults who required preoperative ABD before elective orthognathic surgery. Measurements were conducted with m-HUT during ABD and postphlebotomy infusion.
