The aim of this study was to investigate the awareness and experience, among dental practitioners, of adverse events resulting from dental treatment of patients undergoing therapy with drugs that affect the immune system [angiogenesis inhibitors, biological agents, immunosuppressants, and disease-modifying anti-rheumatic drugs (DMARDs)]. For this purpose, a nationwide questionnaire survey was conducted. Questionnaires were sent to 2,050 dentists, of which 206 (10.

The purpose of this study was to investigate the contents of dental treatment-related complications in Japanese patients during molecular targeted therapy.
Materials And Methods: The nation-wide survey of dental treatment related complications was performed by the Japanese Society of Dentistry for Medically Compromised Patient as retrospective cohort study.
This study was a prospective, multicentre, cohort study on 685 patients who had undergone oncologic surgery. The patients were divided into two groups according to the presence or absence of postoperative pneumonia. The two groups were compared with respect to their background, index operation, food eaten, oral condition, contents of oral care and dental treatment, laboratory data, and bacterial flora.

When tumor cells invaginate into the stroma, the cells are exposed to extracellular environments, including the extracellular matrix (ECM). Increased ECM stiffness has been reported to promote cellular biological activities, such as excessive cellular growth and enhanced migration capability.

In this study, the histopathological effects and toxicities following concurrent chemoradiotherapy were examined. The subjects consisted of 15 patients (10 men and 5 women) who were treated with S-1 (60-80 mg/day, 4 weeks), superselective intra-arterial infusion of CBDCA (300 mg/body) and radiation therapy (total dose 30-36 Gy) in our department from 2005 to 2009.

Methods: We investigated management of antithrombotic therapy at dental extraction, biopsy or polypectomy under an endoscope, an operation of a cataract, pacemaker implantation by questionnaire survey for doctors and dentists in 64 national hospital organization hospitals (NHO-hospital) and doctors in 163 hospitals participated in the Japan Multicenter Stroke Investigators' Collaboration (J-MUSIC) study. We compared the results between NHO-hospitals and J-MUSIC hospitals.
Purpose: The questionnaire survey was performed in order to clarify correspondence of medical doctors and dentists working at hospital service for warfarin therapy at the dental extraction.
Methods: For 17 senior dentists in 17 hospitals and 142 senior physicians in 82 hospitals in Fukuoka City, we investigated using the questionnaire whether they supported dental extraction under warfarin therapy or not in patients having warfarin treatment with past history of cardioembolic stroke due to non-valvular atrial fibrillation (NVAF). Specialty and experience of stroke after withdrawal of warfarin were also asked in medical doctors.

Objective: We sought to clarify the correlation among a computed tomography (CT) or a panoramic radiography (PR) pattern of bone destruction, a histologic pattern of bone destruction, and a mode of invasion in carcinoma of the mandibular gingiva.
Study Design: CT images, panoramic radiographs, and decalcified, hematoxylin-eosin-stained preparations of the excised mandibular bone of 62 patients with carcinoma of the mandibular gingiva were retrospectively evaluated. Each computed tomograph, panoramic radiograph, and the histologic pattern of bone destruction was classified as 1 of 5 types: erosive, erosive and partly mixed, mixed, mixed and partly invasive, or invasive.
