Intra-oral halitosis is caused by volatile sulfur compounds (VSCs) and can be associated with oral dryness. Trehalose is one of the materials used to relieve oral dryness. The aim of the present study was to investigate the effect of trehalose on halitosis. Methods: This prospective, double-blinded, placebo-controlled, cross-over study enrolled volunteers from Okayama University Hospital. The participants were randomly divided into two groups, with one group receiving trehalose (a 10% trehalose solution) and the other receiving a placebo (distilled water) in a 1:1 allocation. The primary study outcome was the subjective organoleptic test. The secondary outcomes were the concentrations of the VSCs, which were measured using a portable gas chromatography device, and the oral moisture status, which was measured using an oral moisture meter. The planned sample size was 10 participants based on the previous study. Results: The final intention-to-treat analysis was performed using the data from 9 participants. After applying 10% trehalose as an oral spray, the organoleptic score decreased in a time-dependent manner. However, no significant differences were seen between the trehalose and placebo groups. In terms of secondary outcomes, the oral moisture levels increased immediately after the trehalose spray application, and significant differences in the amount of change from the baseline were seen between the trehalose and placebo groups (p = 0.047). No significant differences were seen in any of the other variables (p > 0.05). Conclusions: We could not identify any positive effects on halitosis from a one-time 10% trehalose application as an oral spray in this prospective, double-blinded, placebo-controlled, cross-over study. However, the trehalose application immediately improved the oral moisture levels and was useful for treating oral dryness. en-copyright= kn-copyright= en-aut-name=MiyaiHisataka en-aut-sei=Miyai en-aut-mei=Hisataka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TomofujiTakaaki en-aut-sei=Tomofuji en-aut-mei=Takaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MizunoHirofumi en-aut-sei=Mizuno en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MoritaManabu en-aut-sei=Morita en-aut-mei=Manabu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakaharaMomoko en-aut-sei=Nakahara en-aut-mei=Momoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KataokaKota en-aut-sei=Kataoka en-aut-mei=Kota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SumitaIchiro en-aut-sei=Sumita en-aut-mei=Ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=UchidaYurika en-aut-sei=Uchida en-aut-mei=Yurika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ToyamaNaoki en-aut-sei=Toyama en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=YokoiAya en-aut-sei=Yokoi en-aut-mei=Aya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=Yamanaka-KohnoReiko en-aut-sei=Yamanaka-Kohno en-aut-mei=Reiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=TakeuchiNoriko en-aut-sei=Takeuchi en-aut-mei=Noriko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=MaruyamaTakayuki en-aut-sei=Maruyama en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=EkuniDaisuke en-aut-sei=Ekuni en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= affil-num=1 en-affil=Department of Preventive Dentistry, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Community Oral Health, School of Dentistry, Asahi University kn-affil= affil-num=3 en-affil=Department of Preventive Dentistry, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Oral Health Sciences, Faculty of Health Care Sciences, Takarazuka University of Medical and Health Care kn-affil= affil-num=5 en-affil=Department of Preventive Dentistry, Division of Dentistry, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Preventive Dentistry, Division of Dentistry, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Preventive Dentistry, Division of Dentistry, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Preventive Dentistry, Division of Dentistry, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Preventive Dentistry, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of Preventive Dentistry, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=11 en-affil=Department of Preventive Dentistry, Division of Dentistry, Okayama University Hospital kn-affil= affil-num=12 en-affil=Department of Preventive Dentistry, Division of Dentistry, Okayama University Hospital kn-affil= affil-num=13 en-affil=Department of Preventive Dentistry, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=14 en-affil=Department of Preventive Dentistry, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=halitosis kn-keyword=halitosis en-keyword=trehalose kn-keyword=trehalose en-keyword=oral dryness kn-keyword=oral dryness en-keyword=cross-over study kn-keyword=cross-over study en-keyword=randomized trial kn-keyword=randomized trial END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=24 article-no= start-page=4383 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241126 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Association Between Change in Prognostic Nutritional Index During Neoadjuvant Therapy and Dental Occlusal Support in Patients with Esophageal Cancer Under Neoadjuvant Therapy: A Retrospective Longitudinal Pilot Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: A high prognostic nutritional index (PNI) is associated with good prognosis in patients with esophageal cancer. However, nutritional status often decreases during neoadjuvant therapy. Functional tooth units (FTUs) provide an index for the status of posterior occlusal support. We have previously reported that low PNI is related to low FTUs. Objectives: The purpose of this study was to retrospectively examine whether the status of occlusal support relates to changes in PNI during neoadjuvant therapy in patients with esophageal cancer. Methods: This study included 34 patients who underwent neoadjuvant therapy before esophagectomy (32 men, 2 women; age, 36-82 years) in 2012 at Okayama University Hospital. Patients were divided into the good occlusal support group (FTUs >= 11, n = 18) or poor occlusal support group (FTUs < 11, n = 16), and changes in PNI during neoadjuvant therapy were investigated. Results: PNI decreased significantly after neoadjuvant therapy, particularly in the good occlusal support group, and became more dispersed after neoadjuvant therapy. Decreases in PNI after neoadjuvant therapy showed a significant positive correlation with good occlusal support by multiple regression analysis (p = 0.03). The proportions of patients provided with nutritional intervention (p = 0.02) or early dental intervention (p = 0.04) were lower in the good occlusal support group than in the poor occlusal support group. Conclusions: Even in patients with esophageal cancer with good occlusal support experienced significant declines in PNI during neoadjuvant therapy, potentially due to delayed nutritional and dental interventions. Early multidisciplinary interventions are thus recommended for all patients, regardless of preoperative dental or nutritional status. en-copyright= kn-copyright= en-aut-name=Yamanaka-KohnoReiko en-aut-sei=Yamanaka-Kohno en-aut-mei=Reiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShirakawaYasuhiro en-aut-sei=Shirakawa en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=Inoue-MinakuchiMami en-aut-sei=Inoue-Minakuchi en-aut-mei=Mami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YokoiAya en-aut-sei=Yokoi en-aut-mei=Aya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NomaKazuhiro en-aut-sei=Noma en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TanabeShunsuke en-aut-sei=Tanabe en-aut-mei=Shunsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MaedaNaoaki en-aut-sei=Maeda en-aut-mei=Naoaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=FujiwaraToshiyoshi en-aut-sei=Fujiwara en-aut-mei=Toshiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MoritaManabu en-aut-sei=Morita en-aut-mei=Manabu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=EkuniDaisuke en-aut-sei=Ekuni en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Preventive Dentistry, Division of Dentistry, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Oral Rehabilitation and Regenerative Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Preventive Dentistry, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Preventive Dentistry, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of Preventive Dentistry, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=esophageal cancer kn-keyword=esophageal cancer en-keyword=prognostic factors kn-keyword=prognostic factors en-keyword=nutrition kn-keyword=nutrition en-keyword=neoadjuvant therapy kn-keyword=neoadjuvant therapy en-keyword=dental occlusion kn-keyword=dental occlusion END start-ver=1.4 cd-journal=joma no-vol=32 cd-vols= no-issue=12 article-no= start-page=809 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241120 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Relationship among cancer treatment, quality of life, and oral function in head and neck cancer survivors: A cross-sectional study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose Treatment for head and neck cancer (HNC), such as surgery and chemoradiotherapy, can reduce oral function and affect quality of life (QoL). However, whether HNC treatment affects QoL via the decline of oral function remains unclear. This study aimed to investigate the relationship among cancer treatment, QoL, and actual oral function in HNC survivors.
Methods A total of 100 HNC survivors who had completed definitive treatment for HNC at least 6 months prior to enrollment were enrolled in this cross-sectional study. QoL was evaluated using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 summary score. Oral diadochokinesis (ODK), tongue pressure, moisture level on the mucosal surface, and mouth opening were measured. Information on age, sex, tumor site, tumor stage, history of HNC treatment, height, body weight, and lifestyle were collected from medical records. Structural equation modeling (SEM) was conducted to analyze the indirect/direct associations among HNC treatment, QoL, and oral function.
Results In total, 100 HNC survivors (58 males and 42 females; age range, 30–81 years, median, 67 years) were analyzed. Overall, 63 patients (63.0%) were diagnosed as oral cancer, 66 (66.0%) developed advanced cancer (stage 3/4), and 58 (58.0%) underwent reconstruction surgery in 100 HNC survivors. The SEM results supported the hypothesized structural model (root mean square error of approximation = 0.044, comparative fit index = 0.990, Tucker-Lewis index = 0.986). Surgery with neck dissection and reconstruction for advanced cancer had indirect effects on lower QoL via ODK and mouth opening.
Conclusion HNC treatment is indirectly associated with QoL via oral function in HNC survivors. en-copyright= kn-copyright= en-aut-name=YokoiAya en-aut-sei=Yokoi en-aut-mei=Aya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MaruyamaTakayuki en-aut-sei=Maruyama en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamanakaReiko en-aut-sei=Yamanaka en-aut-mei=Reiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakeuchiNoriko en-aut-sei=Takeuchi en-aut-mei=Noriko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MoritaManabu en-aut-sei=Morita en-aut-mei=Manabu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=EkuniDaisuke en-aut-sei=Ekuni en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Preventive Dentistry, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Preventive Dentistry, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Preventive Dentistry, Division of Dentistry, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Preventive Dentistry, Division of Dentistry, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Oral Health Sciences, Takarazuka University of Medical and Health Care kn-affil= affil-num=6 en-affil=Department of Preventive Dentistry, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Quality of life kn-keyword=Quality of life en-keyword=Oral function kn-keyword=Oral function en-keyword=Head and neck cancer kn-keyword=Head and neck cancer en-keyword=ODK kn-keyword=ODK en-keyword=Tongue pressure kn-keyword=Tongue pressure END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=1 article-no= start-page=23886 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241012 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Perioperative gum-chewing training prevents a decrease in tongue pressure after esophagectomy in thoracic esophageal cancer patients: a nonrandomized trial en-subtitle= kn-subtitle= en-abstract= kn-abstract=Tongue pressure (TP) decreases significantly after esophagectomy in esophageal cancer patients (ECPs). Meanwhile, 2 weeks of gum-chewing training (GCT) significantly increased TP in healthy university students. We examined whether perioperative GCT would decrease the proportion of patients exhibiting a decline in TP at 2 weeks postoperatively, and prevent postoperative complications, in thoracic ECPs (TECPs). This was a single-center interventional study, and nonrandomized study with a historical control group (HCG). TECPs who underwent first-stage radical esophagectomy were recruited. Thirty-two patients of 40 in the gum-chewing group (GCG) were completed perioperative GCT in 3 times daily. Propensity score matching was performed with covariates related to TP including preoperative age, sex, body mass index, and the repetitive saliva swallowing test result, and yielded a matched cohort of 25 case pairs. Eleven GCG patients [44.0%] exhibited significantly lower TP at 2 weeks postoperatively than before esophagectomy was significantly fewer than that of 19 patients [76.0%] in the HCG. The median number of fever days (> 38 degrees C) in the 2 weeks after esophagectomy in the GCG was significantly fewer than those in the HCG. Perioperative GCT may prevent postoperative TP decline and postoperative dysphagia-related complications after esophagectomy. en-copyright= kn-copyright= en-aut-name=Yamanaka-KohnoReiko en-aut-sei=Yamanaka-Kohno en-aut-mei=Reiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShirakawaYasuhiro en-aut-sei=Shirakawa en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YokoiAya en-aut-sei=Yokoi en-aut-mei=Aya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MaedaNaoaki en-aut-sei=Maeda en-aut-mei=Naoaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TanabeShunsuke en-aut-sei=Tanabe en-aut-mei=Shunsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NomaKazuhiro en-aut-sei=Noma en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ShimizuKazuyoshi en-aut-sei=Shimizu en-aut-mei=Kazuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MituhashiToshiharu en-aut-sei=Mituhashi en-aut-mei=Toshiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NakamuraYoshihide en-aut-sei=Nakamura en-aut-mei=Yoshihide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=NanbaSouto en-aut-sei=Nanba en-aut-mei=Souto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=UchidaYurika en-aut-sei=Uchida en-aut-mei=Yurika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=MaruyamaTakayuki en-aut-sei=Maruyama en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=MoritaManabu en-aut-sei=Morita en-aut-mei=Manabu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=EkuniDaisuke en-aut-sei=Ekuni en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= affil-num=1 en-affil=Department of Preventive Dentistry, Division of Dentistry, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=3 en-affil=Department of Preventive Dentistry, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=5 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=6 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=7 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Hospital kn-affil= affil-num=8 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Oral and Maxillofacial Radiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=10 en-affil=Dental Clinic, Kurashiki Medical Check-Up Center kn-affil= affil-num=11 en-affil=Department of Preventive Dentistry, Division of Dentistry, Okayama University Hospital kn-affil= affil-num=12 en-affil=Department of Preventive Dentistry, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=13 en-affil=Department of Oral Health Sciences, Takarazuka University of Medical and Health Care kn-affil= affil-num=14 en-affil=Department of Preventive Dentistry, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Esophageal cancer kn-keyword=Esophageal cancer en-keyword=Esophagectomy kn-keyword=Esophagectomy en-keyword=Gum-chewing training kn-keyword=Gum-chewing training en-keyword=Tongue pressure kn-keyword=Tongue pressure en-keyword=Historical control kn-keyword=Historical control en-keyword=Propensity score matching analysis kn-keyword=Propensity score matching analysis END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=1 article-no= start-page=36 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240506 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Sensitivity and specificity of the question “do you have any concerns regarding your mouth related to undergoing surgery?” for predicting perioperative oral health problems in patients with primary esophageal and lung cancer: a retrospective observational study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Perioperative oral management contributes to the prevention of dental/systemic complications. However, a professional dental checkup before surgery is generally not performed and relies on the patient’s answer to a simple question by medical professionals other than dentists: “Do you have any concerns regarding your mouth related to undergoing surgery?” Here, we evaluated the sensitivity and specificity of this question for predicting perioperative oral health problems in patients with primary esophageal and primary lung cancer.
Methods We performed an oral cavity check in all patients before scheduled surgery for primary esophageal and lung cancer. A total of 183 patients were enrolled (M, 112; F, 71; 24–88 years, median, 69 years), consisting of 61 with primary esophageal cancer (M, 46; F, 15; 24–85 years, median, 69 years) and 122 with primary lung cancer (M, 66; F; 56; 33–88 years, median, 69 years). All subjects provided a response to this question, and an oral cavity check was performed by dentists. The sensitivity and specificity of this question for detecting oral health problems were evaluated retrospectively.
Results Overall sensitivity and specificity for detecting oral health problems were 0.263 and 0.898, respectively. There were no significant differences by sex or disease (primary esophageal or lung cancer).
Conclusion This simple question has low sensitivity but high specificity for detecting oral health problems. Although challenging to detect surgical patients with oral health problems by simply asking questions, the results indicated that patients with oral complaints are more likely to have problems during surgery. en-copyright= kn-copyright= en-aut-name=YoshitomiAiko en-aut-sei=Yoshitomi en-aut-mei=Aiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SogaYoshihiko en-aut-sei=Soga en-aut-mei=Yoshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=Yamanaka-KohnoReiko en-aut-sei=Yamanaka-Kohno en-aut-mei=Reiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MorimatsuHiroshi en-aut-sei=Morimatsu en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Division of Hospital Dentistry, Okayama University Hospital kn-affil= affil-num=2 en-affil=Division of Hospital Dentistry, Okayama University Hospital kn-affil= affil-num=3 en-affil=Division of Hospital Dentistry, Okayama University Hospital kn-affil= affil-num=4 en-affil=Perioperative Management Center, Okayama University Hospital kn-affil= en-keyword=Sensitivity kn-keyword=Sensitivity en-keyword=Specificity kn-keyword=Specificity en-keyword=Perioperative kn-keyword=Perioperative en-keyword=Oral management kn-keyword=Oral management en-keyword=Screening kn-keyword=Screening en-keyword=Question kn-keyword=Question END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue=1 article-no= start-page=49 end-page=55 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200607 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Association of dental occlusal support with the Prognostic Nutritional Index in patients with esophageal cancer who underwent esophagectomy en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background
The Prognostic Nutritional Index is useful for predicting surgical risk and overall survival based on preoperative immunological and nutritional status in patients undergoing digestive organ cancer surgery. The purpose of this study was to examine the association between the Prognostic Nutritional Index and dental status in patients with esophageal cancer who underwent esophagectomy.
Methods
This retrospective case–control study included 73 patients who underwent resection of esophageal cancer (69 males, 4 females; age 36–83). General and dental status were evaluated. The Prognostic Nutritional Index was calculated based on the serum albumin concentration and the total lymphocyte count, and subjects were divided into two groups based on index scores: a higher group, characterized by scores ≥ 45 (n = 54); and a lower group, characterized by scores < 45 (n = 19). Univariate analysis and multiple logistic regression analyses were used to compare between groups.
Results
Total protein, C-reactive protein, the number of sound and total decayed, missing and filled teeth, and the rate of patients with poor dental occlusal support showed significant differences between the lower and higher Prognostic Nutritional Index groups (p < 0.05). Stepwise logistic regression analysis by backward selection approach showed that low total protein, few sound teeth, and poor status of dental occlusal support were significantly associated with the lower Prognostic Nutritional Index (p = 0.007, 0.042, and 0.009, respectively).
Conclusion
Dental status, especially dental occlusal support and the number of sound teeth, showed a positive relationship with the Prognostic Nutritional Index in esophageal cancer patients who underwent esophagectomy. en-copyright= kn-copyright= en-aut-name=Yamanaka-KohnoReiko en-aut-sei=Yamanaka-Kohno en-aut-mei=Reiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShirakawaYasuhiro en-aut-sei=Shirakawa en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=Inoue-MinakuchiMami en-aut-sei=Inoue-Minakuchi en-aut-mei=Mami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YokoiAya en-aut-sei=Yokoi en-aut-mei=Aya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MuroMisato en-aut-sei=Muro en-aut-mei=Misato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KosakiHirotaka en-aut-sei=Kosaki en-aut-mei=Hirotaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TanabeShunsuke en-aut-sei=Tanabe en-aut-mei=Shunsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=FujiwaraToshiyoshi en-aut-sei=Fujiwara en-aut-mei=Toshiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MoritaManabu en-aut-sei=Morita en-aut-mei=Manabu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Division of Hospital Dentistry, Central Clinical Department, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Oral Rehabilitation and Regenerative Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Preventive Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Division of Hospital Dentistry, Central Clinical Department, Okayama University Hospital kn-affil= affil-num=6 en-affil=Division of Hospital Dentistry, Central Clinical Department, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Preventive Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Esophageal cancer surgery kn-keyword=Esophageal cancer surgery en-keyword=Prognostic factor kn-keyword=Prognostic factor en-keyword=Nutrition kn-keyword=Nutrition END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=3 article-no= start-page=300 end-page=308 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=20190402 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Change in tongue pressure and the related factors after esophagectomy: a short-term, longitudinal study. en-subtitle= kn-subtitle= en-abstract= kn-abstract=BACKGROUND:
Dysphagia is a prominent symptom after esophagectomy and may cause aspiration pneumonia. Swallowing evaluation after esophagectomy can predict and help control the incidence of postoperative pneumonia. The aim of this study was to clarify whether the change in tongue pressure was associated with any related factor and postoperative dysphagia/pneumonia in patients with esophageal cancer after esophagectomy.
METHODS:
Fifty-nine inpatients (41 males and 18 females; 33-77 years old) who underwent esophagectomy participated in this study. Measurement of tongue pressure and the repetitive saliva swallowing test (RSST) was performed before esophagectomy (baseline) and at 2 weeks postoperatively. The general data were collected from patients' medical records, including sex, age, type of cancer, cancer stage, location of cancer, operative approach, history of previous chemotherapy, surgical duration, amount of bleeding during surgery, incidences of postoperative complications, intubation period, period between surgery and initiation of oral alimentation, and intensive care unit (ICU) stay, blood chemical analysis, and lifestyle.
RESULTS:
Tongue pressure decreased significantly after esophagectomy (p = 0.011). The decrease of tongue pressure was significantly associated with length of ICU stay and preoperative tongue pressure on multiple regression analysis (p < 0.05). The decrease of tongue pressure in the RSST < 3 or postoperative pneumonia (+) group was significantly greater than in the RSST ≥ 3 (p = 0.003) or pneumonia (-) group (p = 0.021).
CONCLUSIONS:
The decrease in tongue pressure was significantly associated with the length of ICU stay, preoperative tongue pressure, and the incidence of dysphagia and pneumonia among inpatient after esophagectomy. en-copyright= kn-copyright= en-aut-name=YokoiAya en-aut-sei=Yokoi en-aut-mei=Aya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=EkuniDaisuke en-aut-sei=Ekuni en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamanakaReiko en-aut-sei=Yamanaka en-aut-mei=Reiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HataHironobu en-aut-sei=Hata en-aut-mei=Hironobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ShirakawaYasuhiro en-aut-sei=Shirakawa en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MoritaManabu en-aut-sei=Morita en-aut-mei=Manabu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Preventive DentistryOkayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Preventive DentistryOkayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Division of Hospital Dentistry, Central Clinical DepartmentOkayama University Hospital kn-affil= affil-num=4 en-affil=Department of Dentistry and Oral SurgeryNational Hospital Organization Hokkaido Cancer Center kn-affil= affil-num=5 en-affil=Department of Gastroenterological SurgeryOkayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Preventive DentistryOkayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Deglutition kn-keyword=Deglutition en-keyword=Deglutition disorders kn-keyword=Deglutition disorders en-keyword=Esophageal neoplasms kn-keyword=Esophageal neoplasms en-keyword=Esophagectomy kn-keyword=Esophagectomy en-keyword=Intensive care units kn-keyword=Intensive care units END start-ver=1.4 cd-journal=joma no-vol=73 cd-vols= no-issue=1 article-no= start-page=71 end-page=76 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=201902 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Efficacy of Oral Care Provided by Interprofessional Collaboration for a Patient with Esophageal Cancer Associated with Post-polio Syndrome during Neoadjuvant Chemotherapy en-subtitle= kn-subtitle= en-abstract= kn-abstract= Preoperative oral care is helpful to prevent postoperative complications in patients who are undergoing esophagectomy. Here, we report the case of an 81-year-old Japanese man with an upper limb disability caused by post-polio syndrome who was receiving neoadjuvant chemotherapy for esophageal cancer. He had poor oral health status and developed oral complications as a side effect of chemotherapy. He could not brush his teeth by himself. However, infection control by oral care provided by an interprofessional collaboration successfully improved his oral hygiene, and his follow-up involved no severe complications. Interprofessional collaboration is useful especially for patients with upper limb disability. en-copyright= kn-copyright= en-aut-name=Takahashi-ArimasaKeiko en-aut-sei=Takahashi-Arimasa

kn-subtitle= en-abstract= kn-abstract=The detection of infective endocarditis (IE) of oral origin has been previously discussed. However, there are few reports confirming this infection using molecular biological techniques. We herein describe the case of a 67-year-old man who developed IE. Blood culture samples and strains obtained from the gingival and buccal mucosa showed 100% identity to Enterococcus faecalis JCM 5803 on sequencing of 16S rRNA gene fragments. A random amplification of polymorphic DNA (RAPD) analysis showed the same pattern for these samples, thus confirming the identity of E. faecalis isolates in the blood and oral mucosa. Our observations provide novel information regarding the level of identity between IE pathogens and oral bacteria. en-copyright= kn-copyright= en-aut-name=OkuiAkemi en-aut-sei=Okui en-aut-mei=Akemi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SogaYoshihiko en-aut-sei=Soga en-aut-mei=Yoshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KokeguchiSusumu en-aut-sei=Kokeguchi en-aut-mei=Susumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NoseMotoko en-aut-sei=Nose en-aut-mei=Motoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamanakaReiko en-aut-sei=Yamanaka en-aut-mei=Reiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KusanoNobuchika en-aut-sei=Kusano en-aut-mei=Nobuchika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MoritaManabu en-aut-sei=Morita en-aut-mei=Manabu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil= kn-affil=Division of Hospital Dentistry, Central Clinical Department, Okayama University Hospital affil-num=2 en-affil= kn-affil=Division of Hospital Dentistry, Central Clinical Department, Okayama University Hospital affil-num=3 en-affil= kn-affil=Department of Microbiology, Division of Social and Environmental Sciences, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=4 en-affil= kn-affil=Clinical Laboratory, Central Clinical Department, Okayama University Hospital affil-num=5 en-affil= kn-affil=Division of Hospital Dentistry, Central Clinical Department, Okayama University Hospital affil-num=6 en-affil= kn-affil=４Department of Infectious Diseases, Okayama University Hospital affil-num=7 en-affil= kn-affil=１Division of Hospital Dentistry, Central Clinical Department, Okayama University Hospital, Japan, ２Department of Microbiology, Division of Social and Environmental Sciences, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences en-keyword=causative pathogen kn-keyword=causative pathogen en-keyword=identity kn-keyword=identity en-keyword=infective endocarditis kn-keyword=infective endocarditis en-keyword=oral bacteria kn-keyword=oral bacteria END start-ver=1.4 cd-journal=joma no-vol=68 cd-vols= no-issue=6 article-no= start-page=375 end-page=378 dt-received= dt-revised= dt-accepted= dt-pub-year=2014 dt-pub=201412 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Management of Lacerated and Swollen Tongue after Convulsive Seizure with a Mouth Protector: Interprofessional Collaboration Including Dentists in Intensive Care en-subtitle= kn-subtitle= en-abstract= kn-abstract=We encountered a 74-year-old male patient with tongue laceration after convulsive seizures under intensive care. The tongue showed severe swelling, and the right ventral surface had been lacerated by his isolated and pointed right lower canine. Our university hospital has established a perioperative management center, and is promoting interprofessional collaboration, including dentists, in perioperative management. Dentists collaborating in the perioperative management center took dental impressions, with the support of anesthesiologists who opened the patientʼs jaw under propofol sedation, to produce a mouth protector. By raising the patientʼs bite, the completed mouth protector prevented the isolated tooth from contacting the tongue and protected the lacerated wound. Use of the mouth protector prevented the lacerated tongue from coming into contact with the pointed tooth, and the tongue healed gradually. These findings underscore that interprofessional collaboration including dentists can improve the quality of medical care. en-copyright= kn-copyright= en-aut-name=YamanakaReiko en-aut-sei=Yamanaka
