Moderate hypothermia circulatory arrest as a brain-protective strategy for type A aortic dissection.

Objectives: Brain-protective strategies for acute type A aortic dissection (TAAD) remain controversial. Moderate hypothermia circulatory arrest (MHCA) without cerebral perfusion is not commonly used. However, we aimed to assess its safety and efficacy in 358 patients who underwent hemiarch replacement with MHCA for acute type A aortic dissection at our institution from August 2012 to August 2022.

Virtual Imaging for a Complex Case of Previous Coarctation Repair.

Repeated surgical procedures for previous aortic coarctation is challenging. Three-dimensional imaging may be useful to visualize the complex anatomy more clearly than with computed tomography imaging, possibly leading to better outcomes. To evaluate the feasibility and efficacy of virtual imaging for preoperative planning of thoracic aortic surgery in this case, we used Vesalius 3D software, 3-dimensional image processing software, and detailed anatomic exploration.

[A Novel Virtual-reality Imaging System in Cardiovascular Surgery:a Potentially Promising Technology for Surgeons].

Adequate preoperative planning may facilitate successful procedures in cardiovascular surgery. We have developed a system named the Vesalius 3D suite, combining three-dimensional (3D) image-processing software with an optic-tracking spatial navigation, allowing quick, accessible 3D image interpretation for virtual reality (VR) exploration and measurement from one or more of a range of imaging modalities. We present a novel method of virtual imaging analysis for preoperative planning and simulation in cardiovascular surgery using this 3D-VR system.

Association between gonial angle on orthopantomogram and reline frequency in removable partial denture wearers.

Purpose: Removable dentures are a reasonable option for prosthetic treatment. However, continuous residual ridge resorption and reline procedures are inevitable owing to the strong pressure exerted on the mucosa or inappropriate pressure distribution. This study aimed to elucidate the association between the gonial angle on orthopantomogram (GAO) with occlusal force and reline frequency in removable partial denture wearers.

[Oral care for elderly people.].

Oral health care for elderly people is important to improve quality of life, extend healthspan and is related with well being and good death. However, food debris and dental plaque remain in the oral cavity of much elderly people required long-term care and cause systemic disease such as aspiration pneumonitis. Dentist and dental hygienist can keep clean the oral cavity of requiring long-term care and prevent the decline of oral function by professional oral function care, professional oral hygiene care and general oral care with multi-disciplinary.

Gonial Angle Measured by Orthopantomography as a Predictor of Maximum Occlusal Force.

Purpose: To establish the accuracy of measuring the gonial angle on an orthopantomogram (GAO), as defined by the anatomic relationship between the inferior and posterior borders of the mandible. Furthermore, to examine the relationship between GAO and maximum occlusal force (MOF) in the premolar and molar regions of healthy young adults.

Materials And Methods: Orthopantomograms of dry mandibles were obtained in three orientations in the sagittal plane, to represent variation in image acquisition in clinical settings.

Dental implant status of patients receiving long-term nursing care in Japan.

Background: The increase in implant patients is expected to give rise to a new problem: the changing general health status of those who have had implants placed.

Purpose: The aim of this present study was to find out the needs of and proper measures for elderly implant patients in long-term care facilities.

Materials And Methods: A questionnaire was sent by mail to 1,591 long-term care health facilities, daycare services for people with dementia, and private nursing homes for the elderly in the Osaka area, which is in the middle area of Japan, in order to extract patients with cerebrovascular disease or dementia who were possibly at risk of inadequate oral self-care, as well as patients with implants.
