Immunomodulatory aspects in the progression and treatment of oral malignancy
Publication date: November 2019Source: Japanese Dental Science Review, Volume 55, Issue 1Author(s): Nobuo Kondoh, Masako Mizuno-Kamiya, Naoki Umemura, Eiji Takayama, Harumi Kawaki, Kenji Mitsudo, Yasunori Muramatsu, Shinichiro SumitomoAbstractInflammation substantially affects the risk of oral malignancy. Pro-inflammatory cytokine, interferon (IFN)-γ, confers anti-tumor activity using several different mechanisms. Conversely, higher expression of interleukin (IL)-17 is associated with worse prognosis. Monocyte chemotactic protein (MCP)-1 correlates positively with poor long-term survival of head and neck squamous cell car...

Obesity-induced asthma: Role of free fatty acid receptors
Publication date: November 2019Source: Japanese Dental Science Review, Volume 55, Issue 1Author(s): Kentaro Mizuta, Atsuko Matoba, Sumire Shibata, Eiji Masaki, Charles W. Emala SrAbstractObesity is a major risk factor for the development of asthma, and worsens the key features of asthma including airway hyperresponsiveness, inflammation, and airway remodeling. Although pro- and anti-inflammatory adipocytokines may contribute to the pathogenesis of asthma in obesity, the mechanistic basis for the relationship between asthma and obesity remains unclear. In obese individuals, the increased amount of adipose tissue results in ...

Comparison of the quality assurance system of dental professionals in Japan, the EU and the ASEAN
Publication date: November 2019Source: Japanese Dental Science Review, Volume 55, Issue 1Author(s): Jun TsurutaAbstractIn recent years, the society requires a flexible response of the dental society to deal with changes in disease structure in the super-aging society in Japan. Regarding quality of dental care, we need to ensure quality of clinical environment, dental professionals and the system. As globalization expands, the health care professionals move to another country to work. In the European Union(EU), the quality assurance system for the graduated European dentist through the activities in undergraduate education ...

Novel insight into the management of bisphosphonate-related osteonecrosis of the jaw (BRONJ)
Publication date: November 2019Source: Japanese Dental Science Review, Volume 55, Issue 1Author(s): Hiromitsu Kishimoto, Kazuma Noguchi, Kazuki TakaokaSummaryBisphosphonate-related osteonecrosis of the jaw (BRONJ), characterized by refractory bone exposure, has recently emerged as a serious side effect of bisphosphonate (BPs) treatment. We discuss novel insights that may help to improve the efficacy of BRONJ treatment and prevention. Our report highlights the following: (1) The presence of exposed bone in patients taking BPs does not necessarily reflect BRONJ, and diagnoses of oral ulceration with bone sequestration and ma...

R-spondin signaling as a pivotal regulator of tissue development and homeostasis
Publication date: November 2019Source: Japanese Dental Science Review, Volume 55, Issue 1Author(s): Kenichi NaganoAbstractR-spondins (Rspos) are cysteine-rich secreted glycoproteins which control a variety of cellular functions and are essential for embryonic development and tissue homeostasis. R-spondins (Rspo1 to 4) have high structural similarity and share 60% sequence homology. It has been shown that their cysteine-rich furin-like (FU) domain and the thrombospondin (TSP) type I repeat domain are essential for initiating downstream signaling cascades and therefore for their biological functions. Although numerous studie...

☆Symposium: Imaging modalities for drug-related osteonecrosis of the jaw (5), utility of bone scintigraphy and 18F-FDG PET/CT in early detection and risk assessment of medication-related osteonecrosis of the jaw (secondary publication)
Publication date: November 2019Source: Japanese Dental Science Review, Volume 55, Issue 1Author(s): Satoru Watanabe, Kenichi Nakajima, Seigo KinuyaSummaryMedication-related osteonecrosis of the jaw (MRONJ) is a significant side effect of antiresorptive and antiangiogenic drugs. Since MRONJ is intractable, early detection is the best way to limit progression. Bone scintigraphy and 18F- fluorodeoxyglucose positron-emission tomography can detect minimal and subclinical changes in bones earlier than conventional radiological modalities. A differential diagnosis including MRONJ is recommended when abnormally high uptakes are in...
