Twenty-six temporal bones from 13 patients with type 1 diabetes mellitus and 40 temporal bones from 20 patients with type 2 diabetes mellitus were examined. Type 2 diabetic temporal bones were divided into 2 groups according to diabetic management (22 temporal bones with insulin therapy, and 18 with oral hypoglycemic drugs). Age-matched normal control temporal bones were also selected. The vessel wall thickness in the cochlear spiral modiolar artery was measured under a light microscope, and the vessel wall ratio (vessel wall thickness/outer diameter of the vessel×100) was calculated. The vessel wall thickness and vessel wall ratio in type 1 diabetes mellitus were significantly greater than in normal controls. Type 2 diabetic patients with insulin therapy showed significantly greater vessel wall thickness and vessel wall ratios than controls. In type 2 diabetes mellitus, the vessel wall thickness and vessel wall ratio were greater in patients treated with insulin therapy than in those treated with oral hypoglycemic agents. Type 2 diabetic patients with insulin therapy showed an increased vessel wall thickness and vessel wall ratio compared to patients with type 1 diabetes mellitus. In conclusion, the cochlea in patients with diabetes mellitus shows circulatory disturbance compared to age-matched normal controls. en-copyright= kn-copyright= en-aut-name=KariyaShin en-aut-sei=Kariya en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=CureogluSebahattin en-aut-sei=Cureoglu en-aut-mei=Sebahattin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FukushimaHisaki en-aut-sei=Fukushima en-aut-mei=Hisaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MoritaNorimasa en-aut-sei=Morita en-aut-mei=Norimasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=BaylanMuzeyyen Y. en-aut-sei=Baylan en-aut-mei=Muzeyyen Y. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MaedaYukihide en-aut-sei=Maeda en-aut-mei=Yukihide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NishizakiKazunori en-aut-sei=Nishizaki en-aut-mei=Kazunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=PaparellaMichael M. en-aut-sei=Paparella en-aut-mei=Michael M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil= kn-affil=Department of Otolaryngology-Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=2 en-affil= kn-affil=International Hearing Foundation affil-num=3 en-affil= kn-affil=Department of Otolaryngology, Kawasaki Medical School affil-num=4 en-affil= kn-affil=Department of Otolaryngology, Kawasaki Medical School affil-num=5 en-affil= kn-affil=Department of Otolaryngology-Head & Neck Surgery, University of Minnesota affil-num=6 en-affil= kn-affil=Department of Otolaryngology-Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=7 en-affil= kn-affil=Department of Otolaryngology-Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=8 en-affil= kn-affil=International Hearing Foundation en-keyword=diabetes mellitus kn-keyword=diabetes mellitus en-keyword=temporal bone kn-keyword=temporal bone en-keyword=cochlear spiral modiolar artery kn-keyword=cochlear spiral modiolar artery en-keyword=hearing loss kn-keyword=hearing loss END start-ver=1.4 cd-journal=joma no-vol=65 cd-vols= no-issue=1 article-no= start-page=96 end-page=102 dt-received= dt-revised= dt-accepted= dt-pub-year=2016 dt-pub=201601 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Regulatory effect of TLR3 signaling on staphylococcal enterotoxin-induced IL-5, IL-13, IL-17A and IFN-γ production in chronic rhinosinusitis with nasal polyps en-subtitle= kn-subtitle= en-abstract= kn-abstract=BACKGROUND: Toll-like receptor 3 (TLR3) is expressed in upper airways, however, little is known regarding whether Toll-like receptor 3 (TLR3) signals exert a regulatory effect on the pathogenesis of chronic rhinosinusitis with nasal polyps (CRSwNP), especially on eosinophilic inflammation. We sought to investigate the effect of Poly(IC), the ligand for TLR3, on cytokine production by dispersed nasal polyp cells (DNPCs). METHODS: DNPCs were pretreated with or without Poly(IC), and were then cultured in the presence or absence of staphylococcal enterotoxin B (SEB), following which the levels of IL-5, IL-10, IL-13, IL-17A and interferon (IFN)-γ in the supernatant were measured. To determine the involvement of IL-10 and cyclooxygenase in Poly(IC)-mediated signaling, DNPCs were treated with anti-IL-10 monoclonal antibody and diclofenac, the cyclooxygenase inhibitor, respectively. Poly(IC)-induced prostaglandin E2 (PGE2) production was also determined. RESULTS: Exposure to Poly(IC) induced a significant production of IL-10, but not of IL-5, IL-13, IL-17A or IFN-γ by DNPCs. Pretreatment with Poly(IC) dose-dependently inhibited SEB-induced IL-5, IL-13 and IL-17A, but not IFN-γ production. Neutralization of IL-10 significantly abrogated the inhibitory effect of Poly(IC). Treatment with diclofenac also abrogated the inhibitory effect of Poly(IC) on SEB-induced IL-5 and IL-13 production. However, unlike exposure of diclofenac-treated DNPCs to lipopolysaccharide, the ligand for TLR4, exposure of these cells to Poly(IC) did not enhance IL-5 or IL-13 production. Poly(IC) did not significantly increase PGE2 production by DNPCs. CONCLUSIONS: These results suggest that TLR3 signaling regulates eosinophilia-associated cytokine production in CRSwNP, at least in part, via IL-10 production. en-copyright= kn-copyright= en-aut-name=OkanoMitsuhiro en-aut-sei=Okano en-aut-mei=Mitsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FujiwaraTazuko en-aut-sei=Fujiwara en-aut-mei=Tazuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KariyaShin en-aut-sei=Kariya en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HigakiTakaya en-aut-sei=Higaki en-aut-mei=Takaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MakiharaSei-ichiro en-aut-sei=Makihara en-aut-mei=Sei-ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HarunaTakenori en-aut-sei=Haruna en-aut-mei=Takenori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NoyamaYasuyuki en-aut-sei=Noyama en-aut-mei=Yasuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KoyamaTakahisa en-aut-sei=Koyama en-aut-mei=Takahisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OmichiRyotaro en-aut-sei=Omichi en-aut-mei=Ryotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OritaYorihisa en-aut-sei=Orita en-aut-mei=Yorihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=MikiKentaro en-aut-sei=Miki en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=KanaiKengo en-aut-sei=Kanai en-aut-mei=Kengo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=NishizakiKazunori en-aut-sei=Nishizaki en-aut-mei=Kazunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Department of Otolaryngology-Head & Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Otolaryngology-Head & Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Otolaryngology-Head & Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Otolaryngology-Head & Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Otorhinolaryngology, Kagawa Rosai Hospital kn-affil= affil-num=6 en-affil=Department of Otolaryngology-Head & Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Otolaryngology-Head & Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Otolaryngology-Head & Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Otolaryngology-Head & Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Otolaryngology-Head & Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Otolaryngology-Head & Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of Otorhinolaryngology, Kagawa Prefectural Central Hospital kn-affil= affil-num=13 en-affil=Department of Otolaryngology-Head & Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Chronic rhinosinusitis with nasal polyps kn-keyword=Chronic rhinosinusitis with nasal polyps en-keyword=IL-10 kn-keyword=IL-10 en-keyword=IL-5 kn-keyword=IL-5 en-keyword=Poly(IC) kn-keyword=Poly(IC) en-keyword=Toll-like receptor kn-keyword=Toll-like receptor END start-ver=1.4 cd-journal=joma no-vol=137 cd-vols= no-issue=5 article-no= start-page=529 end-page=533 dt-received= dt-revised= dt-accepted= dt-pub-year=2017 dt-pub=201705 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The impact of chronic rhinosinusitis on long-term survival in lung transplantation recipients en-subtitle= kn-subtitle= en-abstract= kn-abstract=CONCLUSIONS: Chronic rhinosinusitis diagnosed according to the European Position Paper on Rhinosinusitis and Nasal Polyps 2012, not by computed tomography alone, is one of the prognostic factors affecting long-term survival in patients with lung transplantation. Endoscopic sinus surgery might play a beneficial role in the management of lung transplantation recipients with chronic rhinosinusitis. OBJECTIVE: To show the effect of paranasal sinus infection on post-lung transplantation survival. METHOD: Lung transplantation recipients were included in this study. Computed tomography was performed before and after lung transplantation. The severity of chronic rhinosinusitis was evaluated by Lund-Mackay scoring system. The survival rate was calculated by the Kaplan-Meier method. RESULTS: One hundred and forty-eight patients received lung transplantation for various indications. Chronic rhinosinusitis was found in 18.9% (28/148) of the lung transplantation recipients. Of 28 patients with chronic rhinosinusitis, seven patients underwent endoscopic sinus surgery due to persistent post-nasal drip. The recipients with chronic rhinosinusitis who did not receive endoscopic sinus surgery (n = 21) showed a significantly lower survival rate as compared to the patients without chronic rhinosinusitis. There was no statistically significant difference in the survival rate between the recipients with (n = 50) and without (n = 98) paranasal sinus abnormality on computed tomography. en-copyright= kn-copyright= en-aut-name=KariyaShin en-aut-sei=Kariya en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OkanoMitsuhiro en-aut-sei=Okano en-aut-mei=Mitsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OtoTakahiro en-aut-sei=Oto en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HigakiTakaya en-aut-sei=Higaki en-aut-mei=Takaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HarunaTakenori en-aut-sei=Haruna en-aut-mei=Takenori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NodaYohei en-aut-sei=Noda en-aut-mei=Yohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NishizakiKazunori en-aut-sei=Nishizaki en-aut-mei=Kazunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Otolaryngology-Head and Neck Surgery , Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Otolaryngology-Head and Neck Surgery , Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Thoracic Surgery , Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Otolaryngology-Head and Neck Surgery , Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Otolaryngology-Head and Neck Surgery , Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Otolaryngology-Head and Neck Surgery , Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Otolaryngology-Head and Neck Surgery , Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Lung transplant kn-keyword=Lung transplant en-keyword=bronchiolitis obliterans kn-keyword=bronchiolitis obliterans en-keyword=infection; pneumonia kn-keyword=infection; pneumonia en-keyword=survival rate kn-keyword=survival rate END start-ver=1.4 cd-journal=joma no-vol=42 cd-vols= no-issue=8 article-no= start-page=1217 end-page=1226 dt-received= dt-revised= dt-accepted= dt-pub-year=2012 dt-pub=201208 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=COX/PGE(2) axis critically regulates effects of LPS on eosinophilia-associated cytokine production in nasal polyps en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Lipopolysaccharide (LPS) has shown heterogeneous effects on eosinophilic inflammation in airways. However, little is known about how LPS regulates pathogenesis of chronic rhinosinusitis with nasal polyps, a major form of eosinophilic inflammation in the upper airway. Objective We sought to investigate the effect of LPS on cytokine production by dispersed nasal polyp cells (DNPCs). Methods Either diclofenac-treated or untreated DNPCs were cultured with or without staphylococcal enterotoxin B (SEB) in the presence or absence of LPS, after which the levels of IL-5, IL-13, IL-17A and IFN-gamma within the supernatant were measured. The effects of PGE(2) on LPS-induced responses by diclofenac-treated DNPCs were also examined. LPS-induced PGE(2) production and mRNA expression of COX-1, COX-2 and microsomal PGE(2) synthase-1 (m-PGES-1) were measured. Results Staphylococcal enterotoxin B induced IL-5, IL-13, IL-17A and IFN-gamma production by DNPCs. Pre-treatment with LPS prior to SEB stimulation inhibited production of these cytokines. After stimulation with LPS, PGE(2) production and expression of COX-2 and m-PGES-1 mRNA by DNPCs increased significantly. In the presence of diclofenac, the suppressive effects of LPS were eliminated. LPS pre-treatment enhanced SEB-induced IL-5, IL-13 and IL-17A production in diclofenac-treated DNPCs, while addition of PGE(2) inhibited IL-5, IL-13 and IFN-gamma production. LPS alone induced IL-5, IL-13 and IFN-gamma production by diclofenac-treated DNPCs, while the addition of EP2 and EP4 receptor-selective agonists, as well as PGE(2) itself, inhibited IL-5 and IL-13 production. Conclusions and Clinical Relevance These results suggest that the regulatory effects of LPS on eosinophilic airway inflammation are controlled via the COX-2/PGE(2) axis. For clinical implications, indiscreet use of non-steroidal anti-inflammatory drugs should be avoided in patients with chronic rhinosinusitis with nasal polyps. en-copyright= kn-copyright= en-aut-name=HigakiT en-aut-sei=Higaki en-aut-mei=T kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OkanoM en-aut-sei=Okano en-aut-mei=M kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FujiwaraT en-aut-sei=Fujiwara en-aut-mei=T kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MakiharaS en-aut-sei=Makihara en-aut-mei=S kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KariyaS en-aut-sei=Kariya en-aut-mei=S kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NodaY en-aut-sei=Noda en-aut-mei=Y kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HarunaT en-aut-sei=Haruna en-aut-mei=T kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NishizakiK en-aut-sei=Nishizaki en-aut-mei=K kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil= kn-affil=Okayama Univ, Dept Otolaryngol Head & Neck Surg, Grad Sch Med Dent & Pharmaceut Sci affil-num=2 en-affil= kn-affil=Okayama Univ, Dept Otolaryngol Head & Neck Surg, Grad Sch Med Dent & Pharmaceut Sci affil-num=3 en-affil= kn-affil=Okayama Univ, Dept Otolaryngol Head & Neck Surg, Grad Sch Med Dent & Pharmaceut Sci affil-num=4 en-affil= kn-affil=Okayama Univ, Dept Otolaryngol Head & Neck Surg, Grad Sch Med Dent & Pharmaceut Sci affil-num=5 en-affil= kn-affil=Okayama Univ, Dept Otolaryngol Head & Neck Surg, Grad Sch Med Dent & Pharmaceut Sci affil-num=6 en-affil= kn-affil=Okayama Univ, Dept Otolaryngol Head & Neck Surg, Grad Sch Med Dent & Pharmaceut Sci affil-num=7 en-affil= kn-affil=Okayama Univ, Dept Otolaryngol Head & Neck Surg, Grad Sch Med Dent & Pharmaceut Sci affil-num=8 en-affil= kn-affil=Okayama Univ, Dept Otolaryngol Head & Neck Surg, Grad Sch Med Dent & Pharmaceut Sci en-keyword=COX kn-keyword=COX en-keyword=cytokine kn-keyword=cytokine en-keyword=LPS kn-keyword=LPS en-keyword=PGE(2) kn-keyword=PGE(2) en-keyword=Staphylococcal enterotoxin B kn-keyword=Staphylococcal enterotoxin B END start-ver=1.4 cd-journal=joma no-vol=68 cd-vols= no-issue=2 article-no= start-page=216 end-page=224 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=20190430 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Significance of IgG4-positive cells in severe eosinophilic chronic rhinosinusitis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: IgG4 production is regulated by type 2 (IL-4 and IL-13) and regulatory (IL-10) cytokines involved in the pathophysiology of chronic rhinosinusitis (CRS). We sought to determine the pathophysiological characteristics of IgG4-positive cells in sinonasal tissues in CRS, especially eosinophilic CRS (ECRS).
Methods: IgG4-positive cells in uncinate tissues (UT) and nasal polyps (NP) were examined by immunohistochemistry. Associations between the number of IgG4-positive cells and clinicopathological factors were analyzed. Receiver operating characteristics (ROC) analysis was performed to determine the cut-off value of IgG4-positive cells in tissue that can predict the post-operative course.
Results: IgG4 was mainly expressed in infiltrating plasma and plasmacytoid cells, and the number of IgG4-positive cells was significantly higher in NP, especially those from severe ECRS patients, than in UT. In CRS patients, the number of IgG4-positive cells significantly and positively correlated with blood and tissue eosinophilia, radiological severity, and serum level of total IgE. The number of infiltrating IgG4-positive cells was significantly higher in patients with a poor post-operative course (sustained sinus shadow 6 months after surgery) than in those with a good one. The number of IgG4-positive cells in NP could discriminate patients with a good or a poor post-operative course (area under the curve: 0.769). Also, 73.3% sensitivity and 82.5% specificity were achieved when the cut-off value was set at 17 cells/high-power field.
Conclusions: Our results suggest that the local expression of IgG4 on cells may be used as a biomarker that reflects the pathophysiology of CRS, including the post-operative course. en-copyright= kn-copyright= en-aut-name=KoyamaTakahisa en-aut-sei=Koyama en-aut-mei=Takahisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KariyaShin en-aut-sei=Kariya en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SatoYasuharu en-aut-sei=Sato en-aut-mei=Yasuharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=GionYuka en-aut-sei=Gion en-aut-mei=Yuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HigakiTakaya en-aut-sei=Higaki en-aut-mei=Takaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HarunaTakenori en-aut-sei=Haruna en-aut-mei=Takenori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=FujiwaraTazuko en-aut-sei=Fujiwara en-aut-mei=Tazuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MinouraAkira en-aut-sei=Minoura en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TakaoSoshi en-aut-sei=Takao en-aut-mei=Soshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OritaYorihisa en-aut-sei=Orita en-aut-mei=Yorihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KanaiKengo en-aut-sei=Kanai en-aut-mei=Kengo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=TaniguchiMasami en-aut-sei=Taniguchi en-aut-mei=Masami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=NishizakiKazunori en-aut-sei=Nishizaki en-aut-mei=Kazunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=OkanoMitsuhiro en-aut-sei=Okano en-aut-mei=Mitsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= affil-num=1 en-affil=Department of Otolaryngology-Head & Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Otolaryngology-Head & Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Pathology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Pathology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Otolaryngology-Head & Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Otolaryngology-Head & Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Otolaryngology-Head & Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Public Health, Showa University School of Medicine kn-affil= affil-num=9 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Otolaryngology-Head and Neck Surgery, Kumamoto University kn-affil= affil-num=11 en-affil=Department of Otorhinolaryngology-Head & Neck Surgery, Kagawa Prefectural Central Hospital kn-affil= affil-num=12 en-affil=Clinical Research Center for Allergy and Rheumatology, National Hospital Organization Sagamihara National Hospital kn-affil= affil-num=13 en-affil=Department of Otolaryngology-Head & Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=14 en-affil=Department of Otolaryngology-Head & Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Chronic rhinosinusitis kn-keyword=Chronic rhinosinusitis en-keyword=Eosinophils kn-keyword=Eosinophils en-keyword=IgG4 kn-keyword=IgG4 en-keyword=Nasal polyps kn-keyword=Nasal polyps en-keyword=Severity kn-keyword=Severity END start-ver=1.4 cd-journal=joma no-vol=33 cd-vols= no-issue=1 article-no= start-page=183 end-page=189 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=201901 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Relationship Between Renal Dysfunction and Oral Mucositis in Patients Undergoing Concurrent Chemoradiotherapy for Pharyngeal Cancer: A Retrospective Cohort Study. en-subtitle= kn-subtitle= en-abstract= kn-abstract=BACKGROUND/AIM:
The aim of this retrospective cohort study was to investigate the association between renal dysfunction (RD) and the development of oral mucositis (OM) in patients undergoing concurrent chemoradiotherapy (CCRT) for pharyngeal cancer including radiation to the oral cavity.
PATIENTS AND METHODS:
Of 130 patients diagnosed as having pharyngeal cancer who received CCRT at the Okayama University Hospital Head and Neck Cancer Center, 44 were finally selected.
RESULTS:
During the observation period, 24 (54.5%) patients experienced severe OM (grade 3). The Cox proportional hazards regression model demonstrated that RD (hazard ratio(HR)=2.45, 95% confidence interval(CI)=1.067-6.116, p=0.035) and nasopharynx/oropharynx as center of the irradiated area (HR=2.56, 95% CI=1.072-5.604, p=0.034) were significantly associated with the incidence of severe OM (grade 3).
CONCLUSION:
In patients with pharyngeal cancer treated with CCRT including radiation to the oral cavity, RD at baseline can be a risk factor for developing severe OM. en-copyright= kn-copyright= en-aut-name=MIZUNOHIROFUMI en-aut-sei=MIZUNO en-aut-mei=HIROFUMI kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MIYAIHISATAKA en-aut-sei=MIYAI en-aut-mei=HISATAKA 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=KOBAYASHITERUMASA en-aut-sei=KOBAYASHI en-aut-mei=TERUMASA kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=INABUCHIAKI en-aut-sei=INABU en-aut-mei=CHIAKI kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 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=7 ORCID= en-aut-name=MIZUKAWANOBUYOSHI en-aut-sei=MIZUKAWA en-aut-mei=NOBUYOSHI kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KARIYASHIN en-aut-sei=KARIYA en-aut-mei=SHIN kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=NISHIZAKIKAZUNORI en-aut-sei=NISHIZAKI en-aut-mei=KAZUNORI kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KIMATAYOSHIHIRO en-aut-sei=KIMATA en-aut-mei=YOSHIHIRO kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 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=12 ORCID= affil-num=1 en-affil=Department of Preventive Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Preventive Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Preventive Dentistry, 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=Junpukai Daiku Dental Clinic kn-affil= affil-num=6 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Preventive Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Oral and Maxillofacial Reconstructive Surgery, Okayama University Hospital kn-affil= affil-num=9 en-affil=Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of Preventive Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Head and neck cancer kn-keyword=Head and neck cancer en-keyword=concurrent chemoradiotherapy kn-keyword=concurrent chemoradiotherapy en-keyword=creatinine clearance kn-keyword=creatinine clearance en-keyword=oral mucositis kn-keyword=oral mucositis en-keyword=renal dysfunction kn-keyword=renal dysfunction END start-ver=1.4 cd-journal=joma no-vol=46 cd-vols= no-issue=6 article-no= start-page=927 end-page=933 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=20191231 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Methotrexate-associated lymphoproliferative disorder with multiple pulmonary nodules and bilateral cervical lymphadenopathy en-subtitle= kn-subtitle= en-abstract= kn-abstract= As has been well recognized, methotrexate (MTX) leads to a state of immunosuppression and can provide a basis for the development of lymphoproliferative disorders (LPDs). MTX-associated LPDs can affect nodal sites as well as extranodal sites, though the manifestation of an LPD in the form of multiple pulmonary nodules is rare. Here, we report two cases of MTX-associated LPD with multiple bilateral pulmonary nodules, which was a finding suggestive of lung cancer, and bilateral cervical lymphadenopathy. After withdrawal of MTX, the multiple bilateral pulmonary nodules and bilateral cervical lymphadenopathy disappeared without chemotherapy in both cases. From these results, patients with pulmonary nodules and cervical lymphadenopathy should be examined for head and neck malignant tumors. Also, physicians should carefully check the administration of MTX. In patients with an MTX-associated LPD, we need to make an early diagnosis and consider discontinuing the administration of MTX as soon as possible. en-copyright= kn-copyright= en-aut-name=MakiharaSeiichiro en-aut-sei=Makihara en-aut-mei=Seiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KariyaShin en-aut-sei=Kariya en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=Noujima-HaradaMai en-aut-sei=Noujima-Harada en-aut-mei=Mai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OharaNobuya en-aut-sei=Ohara en-aut-mei=Nobuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NaitoTomoyuki en-aut-sei=Naito en-aut-mei=Tomoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MatsumotoJunya en-aut-sei=Matsumoto en-aut-mei=Junya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NodaYohei en-aut-sei=Noda en-aut-mei=Yohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OkanoMitsuhiro en-aut-sei=Okano en-aut-mei=Mitsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YoshinoTadashi en-aut-sei=Yoshino en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=NishizakiKazunori en-aut-sei=Nishizaki en-aut-mei=Kazunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Otolaryngology-Head & Neck Surgery, Kagawa Rosai Hospital kn-affil= affil-num=2 en-affil=Department of Otolaryngology-Head & Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Pathology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, kn-affil= affil-num=4 en-affil=Department of Pathology, Kagawa Rosai Hospital kn-affil= affil-num=5 en-affil=Department of Otolaryngology-Head & Neck Surgery, Kagawa Rosai Hospital kn-affil= affil-num=6 en-affil=Department of Otolaryngology-Head & Neck Surgery, Kagawa Rosai Hospital kn-affil= affil-num=7 en-affil=Department of Otolaryngology-Head & Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Otolaryngology, International University of Health and Welfare School of Medicine kn-affil= affil-num=9 en-affil=Department of Pathology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, kn-affil= affil-num=10 en-affil=Department of Otolaryngology-Head & Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=MTX-associated LPD kn-keyword=MTX-associated LPD en-keyword=Methotrexate kn-keyword=Methotrexate en-keyword=Pulmonary nodules kn-keyword=Pulmonary nodules END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=1 article-no= start-page=209 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=20191121 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Dose distribution of intensity-modulated proton therapy with and without a multi-leaf collimator for the treatment of maxillary sinus cancer: a comparative effectiveness study. en-subtitle= kn-subtitle= en-abstract= kn-abstract=BACKGROUND: Severe complications, such as eye damage and dysfunciton of salivary glands, have been reported after radiotherapy among patients with head and neck cancer. Complications such as visual impairment have also been reported after proton therapy with pencil beam scanning (PBS). In the case of PBS, collimation can sharpen the penumbra towards surrounding normal tissue in the low energy region of the proton beam. In the current study, we examined how much the dose to the normal tissue was reduced by when intensity-modulated proton therapy (IMPT) was performed using a multi-leaf collimator (MLC) for patients with maxillary sinus cancer.
METHODS:
Computed tomography findings of 26 consecutive patients who received photon therapy at Okayama University Hospital were used in this study. We compared D2% of the region of interest (ROI; ROI-D2%) and the mean dose of ROI (ROI-mean) with and without the use of an MLC. The organs at risk (OARs) were the posterior retina, lacrimal gland, eyeball, and parotid gland. IMPT was performed for all patients. The spot size was approximately 5-6 mm at the isocenter. The collimator margin was calculated by enlarging the maximum outline of the target from the beam's eye view and setting the margin to 6 mm. All plans were optimized with the same parameters.
RESULTS:
The mean of ROI-D2% for the ipsilateral optic nerve was significantly reduced by 0.48 Gy, and the mean of ROI-mean for the ipsilateral optic nerve was significantly reduced by 1.04 Gy. The mean of ROI-mean to the optic chiasm was significantly reduced by 0.70 Gy. The dose to most OARs and the planning at risk volumes were also reduced.
CONCLUSIONS:
Compared with the plan involving IMPT without an MLC, in the dose plan involving IMPT using an MLC for maxillary sinus cancer, the dose to the optic nerve and optic chiasm were significantly reduced, as measured by the ROI-D2% and the ROI-mean. These findings demonstrate that the use of an MLC during IMPT for maxillary sinus cancer may be useful for preserving vision and preventing complications. en-copyright= kn-copyright= en-aut-name=SugiyamaSoichi en-aut-sei=Sugiyama en-aut-mei=Soichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KatsuiKuniaki en-aut-sei=Katsui en-aut-mei=Kuniaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TominagaYuki en-aut-sei=Tominaga en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WakiTakahiro en-aut-sei=Waki en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KatayamaNorihisa en-aut-sei=Katayama en-aut-mei=Norihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MatsuzakiHidenobu en-aut-sei=Matsuzaki en-aut-mei=Hidenobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KariyaShin en-aut-sei=Kariya en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KurodaMasahiro en-aut-sei=Kuroda en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NishizakiKazunori en-aut-sei=Nishizaki en-aut-mei=Kazunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KanazawaSusumu en-aut-sei=Kanazawa en-aut-mei=Susumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Departments of Radiology, Dentistry and Pharmaceutical Science, Okayama University Graduate School of Medicine kn-affil= affil-num=2 en-affil=Departments of Proton Beam Therapy, Dentistry and Pharmaceutical Science, Okayama University Graduate School of Medicine kn-affil= affil-num=3 en-affil=Department of Radiation Technology, Tsuyama Chuo Hospital kn-affil= affil-num=4 en-affil=Department of Radiology, Tsuyama Chuo Hospital, Tusyama kn-affil= affil-num=5 en-affil=Departments of Radiology, Okayama University Hospital kn-affil= affil-num=6 en-affil=Departments of Oral Diagnosis and Dentomaxillofacial Radiology, Okayama University Hospital kn-affil= affil-num=7 en-affil=Departments of Otolaryngology-Head and Neck Surgery, Dentistry and Pharmaceutical Science, Okayama University Graduate School of Medicine kn-affil= affil-num=8 en-affil=Department of Radiological Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=9 en-affil=Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Departments of Radiology, Dentistry and Pharmaceutical Science, Okayama University Graduate School of Medicine kn-affil= en-keyword=Chemoradiotherapy kn-keyword=Chemoradiotherapy en-keyword=Intensity-modulated proton therapy kn-keyword=Intensity-modulated proton therapy en-keyword=Maxillary sinus cancer kn-keyword=Maxillary sinus cancer en-keyword=Multi-leaf collimator kn-keyword=Multi-leaf collimator en-keyword=Pencil beam scanning kn-keyword=Pencil beam scanning END start-ver=1.4 cd-journal=joma no-vol=35 cd-vols= no-issue=1 article-no= start-page=145 end-page=148 dt-received= dt-revised= dt-accepted= dt-pub-year=2018 dt-pub=20181101 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Dangerous noodle: A case of swallowing syncope and a review of 122 cases from the literature. en-subtitle= kn-subtitle= en-abstract= kn-abstract= Swallowing syncope is a rare medical condition. Even though it has been known as a neurally mediated syncope, the definitive mechanism of this condition remains unclear. We show in this study an additional case of swallowing syncope and review the 122 reported cases from the literature. A 47-year-old Japanese man had been suffering from recurrent syncopal attacks, when he fainted immediately after swallowing. Holter electrocardiogram monitoring demonstrated a sinus pause (maximum R-R interval of 3.8 seconds) after he swallowed a noodle quickly. A permanent pacemaker was implanted because the frequency of syncope increased. en-copyright= kn-copyright= en-aut-name=UraguchiKensuke en-aut-sei=Uraguchi en-aut-mei=Kensuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KariyaShin en-aut-sei=Kariya en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MakiharaSeiichiro en-aut-sei=Makihara en-aut-mei=Seiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OkaAiko en-aut-sei=Oka en-aut-mei=Aiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=UeedaHiroo en-aut-sei=Ueeda en-aut-mei=Hiroo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NodaYohei en-aut-sei=Noda en-aut-mei=Yohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NishizakiKazunori en-aut-sei=Nishizaki en-aut-mei=Kazunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil= Department of Otolaryngology Kochi Health Sciences Center kn-affil= affil-num=2 en-affil= Department of Otolaryngology-Head and Neck Surgery Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Otolaryngology-Head and Neck Surgery Kagawa Rosai Hospital kn-affil= affil-num=4 en-affil=Department of Otolaryngology-Head and Neck Surgery Kagawa Rosai Hospital kn-affil= affil-num=5 en-affil=Department of Cardiovascular Medicine Kagawa Rosai Hospital kn-affil= affil-num=6 en-affil= Department of Otolaryngology-Head and Neck Surgery Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil= Department of Otolaryngology-Head and Neck Surgery Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=deglutition kn-keyword=deglutition en-keyword=permanent pacemaker kn-keyword=permanent pacemaker en-keyword=sinus arrest kn-keyword=sinus arrest en-keyword=situational syncope kn-keyword=situational syncope en-keyword=wallowing syncope kn-keyword=wallowing syncope END start-ver=1.4 cd-journal=joma no-vol=118 cd-vols= no-issue=11 article-no= start-page=902 end-page=905 dt-received= dt-revised= dt-accepted= dt-pub-year=2004 dt-pub=200411 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Abnormal direction of internal auditory canal and vestibulocochlear nerve en-subtitle= kn-subtitle= en-abstract= kn-abstract=

Establishment of serum biomarkers reflecting the pathophysiology of CRS is desirable in a clinical setting. As IgG4 production is regulated by type 2 cytokines, we sought to determine whether serum IgG4 levels can be used as a biomarker for CRS.
Methods: Association between the serum IgG4 levels and clinicopathological factors was analyzed in 336 CRS patients. Receiver operating characteristics (ROC) analysis was performed to determine the cut-off value of serum IgG4 levels that can be used to predict the post-operative recurrence.
Results: Serum IgG4 levels were significantly higher in patients with moderate to severe ECRS versus those with non to mild ECRS. The levels were also significantly higher in asthmatic patients and patients exhibiting recurrence after surgery compared to controls. ROC analysis determined that the best cut-off value for the serum IgG4 level to predict the post-operative recurrence was 95 mg/dL. The corresponding sensitivity and specificity were 39.7% and 80.5%, respectively. When we combined the two cut-off values for the serum IgG4 and periostin, patients with high serum levels of either IgG4 or periostin exhibited a high post-operative recurrence (OR: 3.95) as compared to patients having low serum levels of both IgG4 and periostin.
Conclusions: The present results demonstrate that the serum IgG4 level is associated with disease severity and post-operative course in CRS. In particular, the combination of serum IgG4 and periostin could be a novel biomarker that predicts post-operative recurrence. en-copyright= kn-copyright= en-aut-name=OkaAiko en-aut-sei=Oka

kn-subtitle= en-abstract= kn-abstract=Background: Vascular endothelial growth factor (VEGF) is known to be associated with the pathogenesis of chronic rhinosinusitis with nasal polyps (CRSwNP). VEGF is produced by a variety of cells including fibroblasts. It was recently reported that prostaglandin (PG) E-2 induces VEGF release by nasal polyp fibroblasts. However, little is known regarding possible regulation of VEGF by other PGs. We have reported that molecules that regulate PGD(2) metabolism play roles in the pathogenesis of CRS including in local eosinophilia and type 2 cytokine production. In the present study, we sought to determine whether PGD(2) regulates VEGF release by nasal polyp fibroblasts.
Methods: Nasal polyp fibroblasts were established from nasal polyps. These fibroblasts were stimulated with serial dilutions of PGD(2) or PGD(2) receptor (DP/CRTH2)-selective agonists in the presence or absence of receptor-selective antagonists. The concentration of VEGF in the culture supernatants was determined using ELISA.
Results: 5 mM of PGD(2) significantly induced VEGF release by nasal polyp fibroblasts. VEGF release was also obtained by stimulation with a DP receptor-selective, but not with a CRTH2 receptor-selective agonist. In addition, PGD(2)-induced VEGF release was significantly inhibited by pre-treatment with DP receptor-selective antagonists. In contrast, pre-treatment with a CRTH2 receptor-selective antagonist significantly enhanced PGD(2)-induced VEGF release.
Conclusions: PGD(2) stimulates VEGF production via DP but not CRTH2 receptors in nasal polyp fibroblasts. Copyright (C) 2016, Japanese Society of Allergology. Production and hosting by Elsevier B.V.

If conservative treatment fails, aggressive treatments including reconstructive surgery with pedicle flap are considered. Negative pressure wound therapy has been used for large skin defects, necrotizing fasciitis, pharyngocutaneous fistula, stoma dehiscence, osteoradionecrosis of the mandible, chyle fistula, flap failure, and lymphangioma in the field of head and neck surgery. We report a case of false vocal cord perforation with abscess successfully treated by negative pressure wound therapy after abscess treatment. The result suggests that negative pressure wound therapy can be an alternative or adjunctive approach for larynx perforation when the perforation is difficult to close after conservative therapy. en-copyright= kn-copyright= en-aut-name=MakiharaSeiichiro en-aut-sei=Makihara en-aut-mei=Seiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KariyaShin en-aut-sei=Kariya en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NaitoTomoyuki en-aut-sei=Naito en-aut-mei=Tomoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=UraguchiKensuke en-aut-sei=Uraguchi en-aut-mei=Kensuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MatsumotoJunya en-aut-sei=Matsumoto en-aut-mei=Junya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NodaYohei en-aut-sei=Noda en-aut-mei=Yohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OkanoMitsuhiro en-aut-sei=Okano en-aut-mei=Mitsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NishizakiKazunori en-aut-sei=Nishizaki en-aut-mei=Kazunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Otolaryngology-Head & Neck Surgery, Kagawa Rosai Hospital kn-affil= affil-num=2 en-affil=Department of Otolaryngology-Head & Neck Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Otolaryngology-Head & Neck Surgery, Kagawa Rosai Hospital kn-affil= affil-num=4 en-affil=Department of Otolaryngology, Kochi Health Sciences Center kn-affil= affil-num=5 en-affil=Department of Otolaryngology-Head & Neck Surgery, Kagawa Rosai Hospital kn-affil= affil-num=6 en-affil=Department of Otolaryngology-Head & Neck Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Otolaryngology-Head & Neck Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Otolaryngology-Head & Neck Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Negative pressure wound therapy kn-keyword=Negative pressure wound therapy en-keyword=false vocal cord perforation kn-keyword=false vocal cord perforation en-keyword=deep neck abscess kn-keyword=deep neck abscess en-keyword=larynx perforation kn-keyword=larynx perforation en-keyword=head and neck fistula kn-keyword=head and neck fistula END start-ver=1.4 cd-journal=joma no-vol=41 cd-vols= no-issue=3 article-no= start-page=364 end-page=370 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=202003 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Role of Macrophage Migration Inhibitory Factor in NLRP3 Inflammasome Expression in Otitis Media en-subtitle= kn-subtitle= en-abstract= kn-abstract=Hypothesis: Macrophage migration inhibitory factor plays an important role in the expression of interleukin (IL)-1β and the nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3) inflammasome in lipopolysaccharide-induced otitis media. Background: NLRP3 inflammasome and macrophage migration inhibitory factor are critical molecules mediating inflammation. However, the interaction between the NLRP3 inflammasome and macrophage migration inhibitory factor has not been fully examined. Methods: Wild-type mice and macrophage migration inhibitory factor gene-deficient (MIF−/−) mice received a transtympanic injection of either lipopolysaccharide or phosphate-buffered saline. The mice were sacrificed 24 hours after the injection. Concentrations of IL-1β, NLRP3, ASC (apoptosis-associated speck-like protein containing a caspase recruitment domain and a pyrin domain), and caspase-1 in the middle ear effusions were measured by enzyme-linked immunosorbent assay. Temporal bones were processed for histologic examination and immunohistochemistry. Results: In the immunohistochemical study using the wild-type mice, positive staining of macrophage migration inhibitory factor, NLRP3, ASC, and caspase-1 were observed in infiltrating inflammatory cells induced by lipopolysaccharide in the middle ear. The number of inflammatory cells caused by lipopolysaccharide administration decreased remarkably in the MIF−/− mice as compared with the wild-type mice. The concentrations of IL-1β, NLRP3, ASC, and caspase-1 increased in the lipopolysaccharide-treated wild-type mice. The MIF−/− mice with lipopolysaccharide had decreased levels of IL-1β, NLRP3, ASC, and caspase-1 as compared with the wild-type mice. Conclusion: Macrophage migration inhibitory factor has an important role in the production of IL-1β and the NLRP3 inflammasome. Controlling the inflammation by modulating macrophage migration inhibitory factor and the NLRP3 inflammasome may be a novel therapeutic strategy for otitis media. en-copyright= kn-copyright= en-aut-name=KariyaShin en-aut-sei=Kariya en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OkanoMitsuhiro en-aut-sei=Okano en-aut-mei=Mitsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ZhaoPengfei en-aut-sei=Zhao en-aut-mei=Pengfei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MaedaYukihide en-aut-sei=Maeda en-aut-mei=Yukihide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KataokaYuko en-aut-sei=Kataoka en-aut-mei=Yuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HigakiTakaya en-aut-sei=Higaki en-aut-mei=Takaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MakiharaSeiichiro en-aut-sei=Makihara en-aut-mei=Seiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NishihiraJun en-aut-sei=Nishihira en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TachibanaTomoyasu en-aut-sei=Tachibana en-aut-mei=Tomoyasu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=NishizakiKazunori en-aut-sei=Nishizaki en-aut-mei=Kazunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Otolaryngology—Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Otolaryngology—Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Otolaryngology—Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Otolaryngology—Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Otolaryngology—Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Otolaryngology—Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Otolaryngology—Head and Neck Surgery, Kagawa Rosai Hospital kn-affil= affil-num=8 en-affil=Department of Medical Bioinformatics, Hokkaido Information University kn-affil= affil-num=9 en-affil=Departments of Otolaryngology, Japanese Red Cross Society Himeji Hospital kn-affil= affil-num=10 en-affil=Department of Otolaryngology—Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Cytokine kn-keyword=Cytokine en-keyword=Infection kn-keyword=Infection en-keyword=Inflammation kn-keyword=Inflammation en-keyword=Interleukin kn-keyword=Interleukin en-keyword=NOD-like receptor kn-keyword=NOD-like receptor en-keyword=Toll-like receptor kn-keyword=Toll-like receptor END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200515 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Immediate changes in transcription factors and synaptic transmission in the cochlea following acoustic trauma: A gene transcriptome study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Pathologic mechanisms in cochleae immediately following the onset of noise-induced hearing loss (NIHL) remain unclear. In this study, mice were exposed to 120 dB of octave band noise for 2 h to induce NIHL. Three hours after noise exposure, expression levels of the whole mouse genome in cochleae were analyzed by RNA-seq and DNA microarray. Differentially expressed genes (DEGs) exhibiting >2-fold upregulation or downregulation in noise-exposed cochleae compared to controls without noise exposure were identified. RNA-seq and microarray analyses identified 273 DEGs regulated at 3 h post-noise (51 upregulated and 222 downregulated). Bioinformatic analysis revealed that these DEGs were associated with the functional gene pathway "neuroactive ligand-receptor interaction" and included 28 genes encoding receptors for neurotransmitters such as gamma-aminobutyric acid and glutamate. Other DEGs included 25 genes encoding transcription factors. Downregulation of 4 neurotransmitter receptors (Gabra3, Gabra5, Gabrb1, Grm1) and upregulations of 5 transcription factors (Atf3, Dbp, Helt, Maff, Nr1d1) were validated by RT-PCR. The differentially regulated transcription factor Atf3 immunolocalized to supporting cells and hair cells in the organ of Corti at 12-h post-noise. The present data serve as a basis for further studies aimed at developing medical treatments for acute sensorineural hearing loss. en-copyright= kn-copyright= en-aut-name=MaedaYukihide en-aut-sei=Maeda en-aut-mei=Yukihide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KariyaShin en-aut-sei=Kariya en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=UraguchiKensuke en-aut-sei=Uraguchi en-aut-mei=Kensuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakaharaJunko en-aut-sei=Takahara en-aut-mei=Junko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FujimotoShohei en-aut-sei=Fujimoto en-aut-mei=Shohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SugayaAkiko en-aut-sei=Sugaya en-aut-mei=Akiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NishizakiKazunori en-aut-sei=Nishizaki en-aut-mei=Kazunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Otolaryngology- Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Otolaryngology- Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Otolaryngology- Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Otolaryngology- Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Otolaryngology- Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Otolaryngology- Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Otolaryngology- Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=DNA microarray kn-keyword=DNA microarray en-keyword=Immunohistochemistry kn-keyword=Immunohistochemistry en-keyword=Mouse cochlea kn-keyword=Mouse cochlea en-keyword=Neurotransmission kn-keyword=Neurotransmission en-keyword=Noise-induced hearing loss kn-keyword=Noise-induced hearing loss en-keyword=RNA-seq kn-keyword=RNA-seq en-keyword=Real-time RT-PCR kn-keyword=Real-time RT-PCR en-keyword=Transcription factor kn-keyword=Transcription factor END start-ver=1.4 cd-journal=joma no-vol=30 cd-vols= no-issue= article-no= start-page=22 end-page=25 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=202012 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A case of rhinocerebral mucormycosis with brain abscess drained by endoscopic endonasal skull base surgery en-subtitle= kn-subtitle= en-abstract= kn-abstract=A 70-year-old Japanese man undergoing remission induction therapy for acute monocytic leukemia (AML-M5b) developed fever and headache, and was started on antibiotics and liposomal amphotericin B (L-AMB).

In this mouse study, real-time RT-PCR array targeting 84 immune-related genes revealed that the expressions of 40 genes (47.6%) were differentially regulated with greater than a twofold change in 12-month-old cochleae with ARHL relative to young control mice, 33 (39.3%) of which were upregulated. These differentially regulated genes (DEGs) were involved in functional pathways for cytokine-cytokine receptor interaction, chemokine signaling, TNF signaling, and Toll-like receptor signaling. An NF-kappa B subunit, Nfkb1, was upregulated in aged cochleae, and bioinformatic analyses predicted that NF-kappa B would interact with the genomic regulatory regions of eight upregulated DEGs, including Tnf and Ptgs2. In aging cochleae, major proinflammatory molecules, IL1B and IL18rap, were upregulated by 6 months of age and thereafter. Remarkable upregulations of seven immune-related genes (Casp1, IL18r1, IL1B, Card9, Clec4e, Ifit1, and Tlr9) occurred at an advanced stage (between 9 and 12 months of age) of ARHL. Immunohistochemistry analysis of cochlear sections from the 12-month-old mice indicated that IL-18r1 and IL-1B were localized to the spiral ligament, spiral limbus, and organ of Corti. The two NF-kappa B-interacting inflammatory molecules, TNF alpha and PTGS2, immunolocalized ubiquitously in cochlear structures, including the lateral wall (the stria vascularis and spiral ligament), in the histological sections of aged cochleae. IBA1-positive macrophages were observed in the stria vascularis and spiral ligament in aged mice. Therefore, inflammatory and immune reactions are modulated in aged cochlear tissues with ARHL. en-copyright= kn-copyright= en-aut-name=UraguchiKensuke en-aut-sei=Uraguchi en-aut-mei=Kensuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MaedaYukihide en-aut-sei=Maeda en-aut-mei=Yukihide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakaharaJunko en-aut-sei=Takahara en-aut-mei=Junko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OmichiRyotaro en-aut-sei=Omichi en-aut-mei=Ryotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FujimotoShohei en-aut-sei=Fujimoto en-aut-mei=Shohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KariyaShin en-aut-sei=Kariya en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NishizakiKazunori en-aut-sei=Nishizaki en-aut-mei=Kazunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=AndoMizuo en-aut-sei=Ando en-aut-mei=Mizuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Otolaryngology- Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Otolaryngology- Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Otolaryngology- Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Otolaryngology- Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Otolaryngology- Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Otolaryngology- Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Otolaryngology- Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Otolaryngology- Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=2 article-no= start-page=454 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220210 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Clinicopathologic Analysis of Sinonasal Inverted Papilloma, with Focus on Human Papillomavirus Infection Status en-subtitle= kn-subtitle= en-abstract= kn-abstract=Sinonasal inverted papilloma (SNIP) can recur; however, the factors related to tumor recurrence remain unclear. This study aimed to analyze risk factors, including human papillomavirus (HPV) infection, as well as other factors associated with SNIP recurrence. Thirty-two patients who were diagnosed with SNIP and underwent surgery between 2010 and 2019 were enrolled: 24 men and 8 women, with a mean age of 59.2 years. The mean follow-up was 57.3 months. Demographics and information about history of smoking, diabetes mellitus (DM), hypertension, allergic rhinitis, alcohol consumption, tumor stage, surgical approach, and recurrence were reviewed retrospectively. Specimens were investigated using polymerase chain reaction to detect HPV DNA (high-risk subtypes: 16, 18, 31, 33, 35, 52b, and 58; low-risk subtypes: 6 and 11). Seven patients (21.9%) experienced recurrence. HPV DNA was detected in five (15.6%) patients (high-risk subtypes, n = 2; low-risk subtypes, n = 3). Patients with recurrence of SNIP had a higher proportion of young adults and displayed higher rates of HPV infection, DM, and advanced tumor stage than those without recurrence. HPV infection, young adulthood, DM, and advanced tumor stage could be associated with a high recurrence rate, which suggests that patients with these risk factors could require close follow-up after surgery. en-copyright= kn-copyright= en-aut-name=TsumuraMunechika en-aut-sei=Tsumura en-aut-mei=Munechika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MakiharaSeiichiro en-aut-sei=Makihara en-aut-mei=Seiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NishikoriAsami en-aut-sei=Nishikori en-aut-mei=Asami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=GionYuka en-aut-sei=Gion en-aut-mei=Yuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MoritoToshiaki en-aut-sei=Morito en-aut-mei=Toshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MiyamotoShotaro en-aut-sei=Miyamoto en-aut-mei=Shotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NaitoTomoyuki en-aut-sei=Naito en-aut-mei=Tomoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=UraguchiKensuke en-aut-sei=Uraguchi en-aut-mei=Kensuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OkaAiko en-aut-sei=Oka en-aut-mei=Aiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TachibanaTomoyasu en-aut-sei=Tachibana en-aut-mei=Tomoyasu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=OritaYorihisa en-aut-sei=Orita en-aut-mei=Yorihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=KariyaShin en-aut-sei=Kariya en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=OkanoMitsuhiro en-aut-sei=Okano en-aut-mei=Mitsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=AndoMizuo en-aut-sei=Ando en-aut-mei=Mizuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=SatoYasuharu en-aut-sei=Sato en-aut-mei=Yasuharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= affil-num=1 en-affil=Department of Otolaryngology Head and Neck Surgery, Kagawa Rosai Hospital kn-affil= affil-num=2 en-affil=Department of Otolaryngology Head and Neck Surgery, Dentistry and Pharmaceutical Sciences, Graduate School of Medicine, Okayama University kn-affil= affil-num=3 en-affil=Division of Pathophysiology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=4 en-affil=Division of Pathophysiology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=5 en-affil= kn-affil=Department of Pathology, Kagawa Rosai Hospital affil-num=6 en-affil=Department of Otolaryngology Head and Neck Surgery, Kagawa Rosai Hospital kn-affil= affil-num=7 en-affil=Department of Otorhinolaryngology, Kagawa Prefectural Central Hospital kn-affil= affil-num=8 en-affil=Department of Otolaryngology Head and Neck Surgery, Dentistry and Pharmaceutical Sciences, Graduate School of Medicine, Okayama University kn-affil= affil-num=9 en-affil=Department of Otorhinolaryngology, School of Medicine, International University of Health and Welfare kn-affil= affil-num=10 en-affil=Department of Otolaryngology, Japanese Red Cross Society Himeji Hospital kn-affil= affil-num=11 en-affil=Department of Otolaryngology Head and Neck Surgery, Graduate School of Medicine, Kumamoto University kn-affil= affil-num=12 en-affil=Department of Otolaryngology Head and Neck Surgery, Dentistry and Pharmaceutical Sciences, Graduate School of Medicine, Okayama University kn-affil= affil-num=13 en-affil= Department of Otorhinolaryngology, School of Medicine, International University of Health and Welfare kn-affil= affil-num=14 en-affil=Department of Otolaryngology Head and Neck Surgery, Dentistry and Pharmaceutical Sciences, Graduate School of Medicine, Okayama University kn-affil= affil-num=15 en-affil=Department of Pathology, Dentistry and Pharmaceutical Sciences, Graduate School of Medicine, Okayama University kn-affil= en-keyword=HPV infection kn-keyword=HPV infection en-keyword=sinonasal inverted papilloma kn-keyword=sinonasal inverted papilloma en-keyword=diabetes mellitus kn-keyword=diabetes mellitus en-keyword=young adult kn-keyword=young adult en-keyword=tumor stage kn-keyword=tumor stage END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2005 dt-pub=20050630 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=成人の滲出性中耳炎におけるマクロファージ遊走阻止因子の役割 kn-title=Role of Macrophage Migration Inhibitory Factor in Otitis Media with Effusion in Adults en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=KariyaShin en-aut-sei=Kariya en-aut-mei=Shin kn-aut-name=假谷伸 kn-aut-sei=假谷 kn-aut-mei=伸 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 END
