Abstract
BACKGROUND Postoperative temperature dysregulation affects the length of hospital stay and prognosis. This study evaluated the factors that influence the occurrence of fever in patients after aortic valve replacement surgery. METHODS Eighty-seven consecutive patients who underwent aortic valve replacement surgery were included. Patients' age, sex and body mass index; presence of diabetes mellitus; operation time; blood loss; blood transfusion volume; preoperative and postoperative laboratory findings; presence or absence of oral function management; and fever >38°C were retrospectively analysed through univariate and multiple logistic regression analyses. RESULTS Among the variables, only diabetes mellitus status was significantly associated with fever ⩾38°C. Postoperatively, patients with diabetes mellitus were significantly less likely to develop fever above 38°C and a fever rising to 38°C. CONCLUSIONS This study shows that the presence of comorbid diabetes mellitus decreases the frequency of developing fever >38°C after aortic valve replacement surgery.

Abstract
BACKGROUND The submandibular gland (SMG) is sacrificed during neck dissection in patients undergoing curative surgery for oral squamous cell carcinoma (OSCC). This may cause a decrease in the production of saliva and result in xerostomia. PURPOSE This study aimed to determine the incidence, invasion patterns, risk factors, and prognosis of SMG involvement in OSCC. METHODS The primary predictor variable in this study was SMG involvement, and the secondary predictor was prognosis. MAIN FINDINGS The primary outcome variables were patient characteristics and pathological results for extranodal extension (ENE), perineural invasion (PNI), and pN stage. Four out of 173 patients (2.23 %) showed SMG involvement. Of these cases, one (25 %) was from the primary lesion and three (75 %) were from the metastatic neck lymph nodes (LNs). The primary lesion was located on the lower gingiva, and the other three were from level-Ib LNs with ENE. The pathological PNI was observed in three of the four patients, and ENE was observed in three of the four patients. Preoperative CT and MR revealed SMG invasion and contact in two patients. There were significant differences in the ENE and pN stages between patients with and without SMG involvement (P<0.05). There was a significant difference in the overall survival between patients with (25.0 %) and without (71.5 %) SMG involvement (P = 0.011). CONCLUSIONS SMG involvement was associated with ENE, pN stage, and poor prognosis.

Abstract
OBJECTIVES Immunotherapy with nivolumab for patients with recurrent/metastatic oral squamous cell carcinoma has not been evaluated. Here, we aimed to examine the efficacy, safety, and prognostic factors of nivolumab in these patients. MATERIALS AND METHODS This multicenter retrospective observational study involved patients who received nivolumab between April 2017 and June 2019. The patient characteristics were evaluated for association with progression-free and overall survival. Progression-free and overall survival rates were calculated; parameters that were significant in the univariate analysis were used as explanatory variables. Independent factors for progression-free and overall survival were identified using multivariate analysis. RESULTS Totally, 143 patients were included. The overall response and disease control rates were 27.3% and 46.2%, respectively. The median, 1- and 2-year progression-free survival rates were 2.7 months, 25.4%, and 19.2%, respectively; those for overall survival were 11.2 months, 47.3%, and 33.6%, respectively. The independent factors affecting progression-free survival were performance status and immune-related adverse event occurrence, whereas those affecting overall survival were performance status, target disease, and number of previous lines of systemic cancer therapy. Eight patients reported grade ≥3 immune-related adverse events. CONCLUSION Nivolumab was effective for recurrent/metastatic oral squamous cell carcinoma treatment and was well tolerated by patients.

Abstract
Elective neck dissection (END) is recommended for the management of patients with oral squamous cell carcinoma (OSCC) because of the risk of occult metastasis (OM). We hypothesized that some factors predict poor prognosis regardless of a cN0 END. This study aimed to investigate the predictors of OM and prognostic factors in patients with cN0 OSCC who underwent supraomohyoid neck dissection (SOHND). A retrospective cohort study design was created and implemented. The primary predictive variables in this study were OM and risk factors for poor prognosis after SOHND. A Cox proportional hazard model was used to adjust for the effects of potential confounders on the risk factors for poor prognoses. Among 86 patients with OSCC, OMs were observed in 9 (10.5%). The neutrophil-to-lymphocyte ratio (NLR) and vascular invasion are good markers for detecting OM. A Cox multivariable analysis identified two independent predictors of overall survival: pathologic node (pN) and laterality of END. An independent predictive factor for disease-free survival, the surgical margin, was also identified in this study. According to the pN classification, pN1 patients had a worse survival rate than pN2 patients. Therefore, in the case of pN1, regardless of being cN0, additional adjuvant therapy may be necessary.

Abstract
Generally, systemic chemotherapy is indicated for oral squamous cell carcinoma with distant metastasis and has a poor prognosis. Recently, the advent of molecular targeted drugs, such as cetuximab and immune checkpoint inhibitors, has dramatically improved prognosis, though controlling distant metastasis remains challenging. We report a case of tongue cancer in which lung metastases disappeared in the long term. A 60-year-old Japanese male with squamous cell carcinoma of the tongue underwent preoperative chemoradiotherapy and surgery including subtotal glossectomy, bilateral modified radical neck dissection, and immediate reconstruction with an anterolateral thigh flap. One month after surgery, multiple nodules less than 10 mm in diameter appeared in both lungs on CT imaging. Multiple lung metastases were diagnosed with no local recurrence or regional lymph node metastasis. The patient continues to receive a 4-week treatment course of chemotherapy that included cetuximab every 3 months and the lung metastases were markedly reduced in size or had disappeared. No local recurrence or newly emerged metastases were observed. The patient has been doing well for nine years since the appearance of the lung metastases.

Abstract
Lipopolysaccharide (LPS) derived from Porphyromonas gingivalis (P.g.), which causes periodontal disease, contributes to the development of non-alcoholic steatohepatitis (NASH). We investigated the role of Nrf2, an antioxidative stress sensor, in macrophages in the development of NASH induced by LPS from P.g. We generated macrophage-specific Nrf2 gene rescue mice (Nrf2-mRes), which express Nrf2 only in macrophages, using the cre/loxp system. Wild-type (WT) mice, whole body Nrf2-knockout (Nrf2-KO) mice, and Nrf2-mRes mice were fed a high-fat diet for 18 weeks, and LPS from P.g. was administered intraperitoneally for the last 6 weeks. Nrf2-KO mice developed severe steatohepatitis with liver inflammation and fibrosis compared with WT mice, and steatohepatitis was ameliorated in Nrf2-mRes mice. The mRNA expressions of Toll-like receptor (Tlr)-2, which activates inflammatory signaling pathways after LPS binding, and α-smooth muscle actin (αSma), which promotes hepatic fibrosis, were reduced in Nrf2-mRes mice compared with Nrf2-KO mice. The protein levels of LPS-binding protein in livers were increased in Nrf2-KO mice compared with WT mice; however, the levels were reduced in Nrf2-mRes mice despite similar numbers of F4/80 positive cells, which reflect macrophage/Kupffer cell infiltration into the livers. Nrf2 in macrophages ameliorates NASH through the increased hepatic clearance of LPS.

Abstract
This study aimed to calculate the ratio of maximum standardized uptake values of cervical lymph nodes to maximum standardized uptake values of primary tumors measured by preoperative fluorodeoxyglucose positron-emission tomography in oral cancer patients, and to retrospectively examine the prognostic association and evaluate whether it could be a prognostic factor. We retrospectively examined consecutive Japanese patients diagnosed with oral squamous cell carcinoma who underwent oral cancer resection and cervical dissection between January 2014 and December 2018. The study included 52 patients aged 39-89 years (median age 66.5 years), excluding non-cervical dissection surgery and/or non-underwent preoperative positron-emission tomography. The maximum standardized uptake value of the cervical lymph nodes and primary tumor was measured, and the ratio of maximum standardized uptake values of the lymph nodes to that of the primary tumor was calculated. The median follow-up of 52 patients was 1,465 days (198-2,553 days), and overall survival was significantly worse in patients with a high lymph node-to-tumor standardized uptake values ratio (>0.4739) (5 years, 58.8% vs. 88.2%; P<0.05). Pretreatment lymph node-to-tumor standardized uptake values ratio can be easily calculated, and as a predictor of prognosis, it may be of assistance when considering the treatment strategy for oral cancer.

Abstract
To determine the intracellular behavior of p62, a marker of selective autophagy, in oral potentially malignant disorders (OPMDs). This retrospective study includes 70 patients who underwent biopsy or surgical resection and were definitively diagnosed with OPMDs. Immunohistochemical staining for p62, XPO1, p53, and ki67 was performed on all samples and positive cell occupancy was calculated. We statistically investigated the correlation between protein expression in OPMDs and the association between malignant transformation, clinicopathological characteristics, and occupancy. ki67 expression was negatively correlated with p62 expression in the nucleus (p < 0.01) and positively correlated with p62 expression in the cytoplasm (p < 0.01). For malignant transformation, the expression of p62 in the nucleus (p = 0.03) was significantly lower in malignant transformation cases, whereas the expression of p62 in the cytoplasm (p = 0.03) and the aggregation expression (p < 0.01) were significantly higher. Our results suggest that the function of p62 is altered by its subcellular localization. In addition, defects in selective autophagy occur in cases of malignant transformation, suggesting that p62 is a potential biomarker of the risk of malignant transformation of OPMDs.

Abstract
The success of cell transplantation therapy for ischemic stroke is hindered by the low cell survival rate in poststroke brain, due in part to high free radical production and ensuing oxidative stress. We have developed redox nanoparticles to eliminate reactive oxygen species. In this study, we tested the protective efficacy of these redox nanoparticles in cell culture and a mouse model of ischemic stroke. Induced human dental pulp stem cells were subjected to oxygen-glucose deprivation and reoxygenation to recapitulate ischemia and reperfusion in the penumbra surrounding a cerebral infarct. Cell viability using WST-8 assay, apoptosis using TUNEL, free radicals using MitoSOX, and inflammatory cytokines using ELISA kit were measured in the presence and absence of redox nanoparticles after oxygen-glucose deprivation and reoxygenation. The scavenging activity of redox nanoparticles against reactive oxygen species was detected by electron spin resonance. Moreover, induced cells were transplanted intracerebrally into to the distal middle cerebral artery occlusion model with and without redox nanoparticles, and the survival rate measured. Cell viability was enhanced, while apoptosis, free radical generation, and inflammatory cytokine expression levels were reduced in cultures with redox nanoparticles. Further, reduced redox nanoparticles were detected in the cytoplasm, indicating free radical scavenging. Addition of redox nanoparticles also improved the survival rate of transplanted cells after 6 weeks in vivo. These redox nanoparticles may increase the applicability and success of induced stem cell therapy for ischemic stroke patents by promoting long-term survival.

Abstract
Anterior maxillary distraction osteogenesis (AMDO) surgery for cleft lip and palate involves distraction of a segment of the anterior maxilla and advancement using 2 intraoral buccal bone-borne distraction devices. The anterior part of the maxilla is advanced anteriorly with less relapse which increases maxillary length and does not affect speech. We aimed to evaluate the effects of AMDO, including lateral cephalometric changes. Seventeen patients who had undergone this procedure were included in this retrospective study. The distractors were activated by 0.5 mm twice a day after a 3-day latency period. Lateral cephalometric radiographs were evaluated preoperatively, after distraction and removal of distractors, which were compared using the paired Student's t test. Anterior maxillary advancement was obtained in all patients with a median of 8.0 mm. Complications included nasal bleeding and loosening of distractors; however, there was no tooth damage or abnormal movement. The mean sella-nasion-A point (SNA) angle increased significantly, from 74.91° to 79.66°, the A point-nasion-B point angle from -0.38° to 4.34°, and the perpendicular line from nasion to Frankfort Horizontal (NV)-A point from -5.11 to 0.08 mm. The mean anterior nasal spine-posterior nasal spine length increased significantly from 50.74 to 55.10 mm, and the NV-Nose Tip from 23.59 to 26.27 mm. The mean relapse rate of NV-A was 11.1%. AMDO with bone-borne distractor resulted in less relapse and effectively corrected the maxillary retrusion.

Abstract
We report a case of tophaceous pseudogout that occurred in the temporomandibular joint (TMJ) and presented with skull base destruction. The patient was a 73-year-old woman, who complained of an obstructed ear sensation in December 2021. The otolaryngological examination was unremarkeable, and a computed tomography scan revealed a calcified lesion in the left TMJ. Suspected of having osteochondroma, the patient was brought to our hospital. She was performed tumor resection as much as possible under general anesthesia revealed nodular pseudogout. The patient refused to undergo total resection due to the necessary craniotomy and the risk of postoperative complications. Instead, the patient decided to undergo following-up. One year and 4 months have passed since the biopsy operation, but there is no tendency to re-increase.

Abstract
Primary intraosseous adenoid cystic carcinoma (PIACC) of the jaw is rare. To our knowledge, only 51 cases have been reported in the English literature. We present a rare case of PIACC arising in the mandible with multiple bone metastases and review the previous articles. A 70-year-old woman presented with paresthesia of the right chin and lower gingiva for 4 months. Radiography revealed an irregular radiolucent region on the right side of the ramus, infiltrating to the mandibular canal. Biopsy revealed a pathological diagnosis of adenoid cystic carcinoma. Multiple bone metastases were present in the sternum, scapula, and thighs. The treatment effect was progressive disease for chemotherapy; therefore, best supportive care was provided for 3 years.

Abstract
This study investigated the effect of postoperative deep sedation after oral cancer reconstructive surgery on the occurrence of early postoperative pneumonia and early postoperative delirium. We obtained medical records of 108 consecutive patients who underwent microvascular reconstructive surgery at Tsukuba University Hospital for oral cancer between January 2013 and December 2021. Forty-six of them woke soon after surgery. Ten of these forty-six patients were restless and required immediate sedation within 3 h after surgery. The comparison between sedation group and no sedation group revealed early postoperative pneumonia in the no sedation group; however, sedation was not related to early postoperative delirium. The preoperative albumin levels of patients with postoperative pneumonia were significantly different (p = 0.03) than those of patients without postoperative pneumonia. The performance status (p = 0.02), preoperative albumin level (p = 0.02), and age 75 years or older (p = 0.02) were significantly associated with postoperative delirium. Restless patients and those who could not be sedated experienced delirium and pneumonia. The risk of pneumonia was increased for patients who were difficult to sedate.

Abstract
A 29-year-old Japanese man with food-dependent exercise-induced anaphylaxis (FDEIA) underwent tooth extraction under general anesthesia. FDEIA is a rare condition in which anaphylaxis occurs due to exercise load or oral administration of NSAIDs after ingestion of allergens. Wheat is often the cause in FEDIA, defined as wheat-dependent exercise-induced anaphylaxis (WDEIA). It is an allergy that is not well known in the dental field. Patients may ingest the causative food on a regular basis because they do not develop without factors such as exercise. Post extraction period was uneventful as the patient was instructed not to ingest wheat before the treatment or while he was taking NSAIDs. We were able to safely extract teeth without causing anaphylaxis.

Abstract
Elderly patients with oral squamous cell carcinoma (OSCC) have difficulty undergoing curative surgical treatment due to various factors besides age. The purpose of the present study was to study the factors determining surgery in elderly patients with OSCC. We designed and implemented a retrospective cohort study. The study sample included elderly patients aged ≥ 70 years with OSCC and they were statistically compared between the surgery and non-surgery groups. The primary outcome variable was selecting surgery as the treatment plan, while the secondary outcome was the prognosis of each group. The sample comprised 76 patients aged ≥ 70 years with OSCC, of whom 52 treated with surgery and 24 patients treated with non-surgery. As decision factors, performance status (PS), clinical stage, serum Alb level, body mass index (BMI), and Geriatric Nutritional Risk Index (GNRI) were significantly associated with the selection of surgery. Logistic multivariate analysis identified three independent predictive factors for selecting surgery: Alb (≥3.5 vs. <3.5), PS (0, 1, 2, 3), and clinical stage. According to the decision tree analysis, curative surgery is the recommended treatment strategy for elderly patients with Alb ≥ 3.5 g/dL, PS 0, and stage I, II. In conclusion, Alb, PS, and clinical stage may be the criteria for selecting surgery in elderly patients.

Abstract
We report a case of a 40-year-old Japanese woman with a benign tongue tumor diagnosed as osseous choristoma of the tongue. Resection of the tongue tumor was performed under general anesthesia. The gross examination of the resected specimen showed a bone-like mass measuring 5 × 5 × 3 mm, surrounded by soft tissue. Based on the findings, a histopathological diagnosis of osseous choristoma was established. There was no evidence of tumor recurrence or distant metastasis during the 3-year follow-up.

Abstract
Epstein-Barr virus (EBV) -positive mucocutaneous ulcer (EBVMCU) was first described as a lymphoproliferative disorder in 2010. In recent years, EBVMCU has been reported in the field of oral surgery. On the other hand, medication-related osteonecrosis of the jaw (MRONJ) is an osteomyelitis that occurs in patients receiving antiresorptive agents including bisphosphonates (BP) and/or denosumab developing with bacterial infections such as dental diseases and mucositis. MRONJ caused by EBVMCU in the elderly has not been reported. Here, we report a rare case of MRONJ caused by EBVMCU in the elderly. The patient, an 82-year-old woman, had received BP for more than 2 years. An ulcerative lesion was found in the palatal mucosa; biopsy performed from the site confirmed the diagnosis of EBVMCU. At follow-up, the lesion disappeared spontaneously. At the 6-month follow-up, bone formation was observed at the site of the lesion, and the sequestrum was removed. At the 12-month follow-up healing of the EBVMCU region was seen indicating a good prognosis.

Abstract
Primary intraosseous squamous cell carcinoma (PISCC) arising from dentigerous cysts (DCs) is rare. Herein, we present a rare case of a 35 year-old Japanese man with PISCC arising from a DC. Clinicians should be aware of the potential for malignant changes to SCC in asymptomatic DCs and should conduct follow-up. Moreover, histological examination of the entire specimen should be performed even if the lesion is suspected to be benign.

Abstract
MicroRNAs (miRNAs) play an important role in carcinogenesis and cancer progression. The purpose of this study was to identify miRNAs associated with carcinoma function in OSCC and to investigate the potential role of the specific miRNAs. First, a comprehensive microarray analysis was performed, and miR-142-5p was identified as a candidate miRNA involved in OSCC. miR-142-5p has been reported to show high expression levels in cancer patients and to be involved in tumor growth and metastasis. However, the expression and function of miR-142-5p in oral squamous cell carcinoma (OSCC) are not fully characterized. We evaluated miR-142-5p expression in both OSCC-derived cell lines and primary OSCC tissues and performed functional analysis of miR-142-5p in OSCC-derived cell lines using mimics and inhibitors. miR-142-5p expression was up-regulated in OSCC tissues and OSCC cell lines. Overexpression of miR-142-5p significantly promoted the proliferation and invasion of OSCC cells. Bioinformatics analysis was performed using TargetScan to predict potential target sites that match the seed region of miR-142-5p. Phosphatase and tensin homolog deleted on chromo-some 10 (PTEN) was identified as a potential target and selected for further analysis. PTEN expression levels were down-regulated and AKT expression levels were up-regulated in miR-142-5p-overexpressing cells. We have shown that miR-142-5p targets the PTEN gene and is involved in cancer progression. Our results suggest that miR-142-5p is involved in the progression of OSCC by controlling the phosphatidylinositol 3-kinase (PI3K)/AKT pathway by targeting the PTEN gene. Our findings suggest that miR-142-5p may be a new target for the treatment of OSCC.

Abstract
Objectives In recent years, many studies have reported that the presurgical nasoalveolar molding method improves the nose morphology; however, the reason for its effectiveness after surgery has never been understood. We evaluated the effect of nasoalveolar molding by comparing it with a passive orthopedic method without a nasal stent and focusing on the nostril morphology after primary cheiloplasty using various measurement methods. We then analyzed the essential factors. Materials and methods The patients involved were 31 infants with unilateral complete cleft lip and palate treated with primary cheiloplasty at the University of Tsukuba Hospital from 2004 to 2011. Of the 31 infants, 16 received nasoalveolar molding treatment and 15 received passive orthopedic treatment as controls. Photographic facial measurements were performed for all patients immediately and 7 months after primary cheiloplasty. The esthetics of the nostrils were assessed according to the left–right nostril symmetry, as measured by the Hausdorff distance, area ratio, perimeter ratio, and aspect a/u (the aspect ratio of the affected side)/(the aspect ratio of the unaffected side) ratio. In addition, the inclination of the nasal ridge was assessed using anthropometric measurements (Grc‐Grn∠midline and midline∠columellar axis). Results The area ratio, perimeter ratio, and Grc‐Grn∠midline were significantly greater in the nasoalveolar molding group immediately after surgery (p = 0.00062, 0.016, and 0.048, respectively) than in the control group. However, the Hausdorff distance and aspect a/u ratio were more favorable (p = 0.0018 and 0.0039, respectively) in the nasoalveolar molding group after 7 months. Conclusions The results of our study suggested that using nasoalveolar molding as a presurgical orthopedic treatment could improve the shape of the nasal cartilage with surgeon's corrections.

Abstract
We investigated the value of the weighted lymph node ratio (WLNR), a new marker in pN0 patients that incorporates the number of metastatic lymph nodes with extranodal extension and the lymph node yield, for the prognosis and postsurgical management of oral squamous cell carcinoma (OSCC). We designed a retrospective study and enrolled patients with OSCC who were treated by neck dissection (ND). The predictor variable was WLNR, and the outcome variable was overall survival (OS). The Cox proportional-hazards model was used to identify independent prognostic factors. In 133 patients with OSCC, the WLNR cut-off value for predicting OS was 0.0363 (area under the curve 0.723, p<0.001). When stratified according to WLNR, there was a significant difference in OS (88.4% for low WLNR and 63.0% for high WLNR, p<0.001). Univariate analyses showed close associations between OS and age, dissection area, postoperative management, extranodal extension, number of positive lymph nodes, pN stage, WLNR, and nodal disease area. Cox multivariate analysis identified the WLNR as an independent predictive factor for OS (HR 3.273, 95% CI 1.227 to 8.731, p=0.018). As a predictive factor, a high WLNR (≥0.0363) in patients with pN0 disease, which included the addition of extranodal extension and lymph node yield to the LNR, was associated with diminished survival.

Abstract
The systemic inflammatory response is known to be associated with poor outcomes in patients with various types of cancer. The C-reactive protein (CRP)/albumin (Alb) ratio (CAR) has been reported as a novel inflammation-based prognostic marker. We have evaluated the prognostic value of inflammatory markers for patients with oral squamous cell carcinoma (OSCC). The study population included 205 patients treated with OSCC between 2013 and 2018. The primary predictor variable was the inflammatory markers. The primary outcome variable was overall survival (OS). Univariate and multivariate analyses were performed using a Cox proportional hazards model to identify independent prognostic factors. The CAR had the highest area under the curve (AUC) values compared with other markers in the receiver operating characteristic (ROC) curve analysis. The cutoff value for CAR was 0.032 (AUC 0.693, P < 0.001). There was a significant difference in OS when patients were stratified according to CAR, with 79.1% for CAR < 0.032 and 35% for CAR ≥ 0.032 (P < 0.001). Cox multivariate analysis identified independent predictive factors for OS: age (hazard ratio [HR] 2.155, 95% confidence interval [CI] 1.262–3.682; P = 0.005), stage (HR 3.031, 95% CI 1.576–5.827; P = 0.001), and CAR (HR 2.859, 95% CI 1.667–4.904; P < 0.001). CAR (≥ 0.032 vs. < 0.032) is a good prognostic marker in patients with OSCC in terms of age and stage.

Abstract
The prevalence of medication-related osteonecrosis of the jaw (MRONJ) associated with molecular-targeted therapies such as bevacizumab and sunitinib has been constantly increasing in recent years. MRONJ frequently occurs after invasive dental procedures such as tooth extraction in patients currently or with a previous history of receiving antiresorptive agents including bisphosphonates and/or denosumab. Here, we report a rare case of spontaneously occurring MRONJ of the mandible in a 52-year-old Japanese woman with chronic myelogenous leukemia (CML) who was administered imatinib for 9 years. She had never been treated with antiresorptive agents, and her MRONJ developed spontaneously. Although there have been few reports of MRONJ related to imatinib, our case reported here indicates that imatinib may be capable of causing spontaneous MRONJ.

Abstract
PURPOSE Detecting deep vein thrombosis (DVT) is necessary to reduce the morbidity of venous thromboembolism, and platelet-lymphocyte ratio (PLR) is a novel marker for predicting DVT. This study aimed to investigate the association between preoperative PLR and risk of developing DVT in patients receiving surgical treatment of oral cancer. PATIENTS AND METHODS We designed a retrospective cohort study, and the source of study sample was patients with oral cancer and who underwent surgery between 2015 and 2019. Patients were excluded if they did not undergo surgical treatment and had preoperative DVT and history of hypercoagulable disorders. The primary predictor variable was PLR. We calculated the receiver operating characteristic curve and area under the curve to determine the best-defined risk groups. The best cutoff value for PLR was 187.4 (area under the curve, 0.772; sensitivity, 75.0%; specificity, 74.2%; P = .002). The primary outcome variable was DVT, and the other variables were patient characteristics, blood examination data, and therapeutic data. A logistic regression analysis was used to adjust the effects of potential confounders. RESULTS A total of 101 patients were included in this study, and DVT was observed in 12 (11.9%) patients. Free flap reconstructive surgery was performed in 8 of the 12 (66.7%) patients in the DVT group. Statistical analyses showed that DVT was significantly associated with PLR (≤187.4 vs >187.4; P = .001). Logistic multivariate analysis of the preoperative parameters identified the following 2 independent predictive factors for DVT: PLR (≤187.4 vs >187.4) (odds ratio, 13.735; 95% confidence interval, 2.950 to 63.944; P = .001) and free flap reconstructive surgery (odds ratio, 6.584; 95% confidence interval, 1.504 to 28.822; P = .012). CONCLUSIONS High PLR (>187.4) and free flap reconstructive surgery, considered as preoperative predictive factors, were associated with DVT.

Abstract
We report a rare case of lymph node metastasis of papillary thyroid cancer (PTC) incidentally detected in a neck dissection specimen of tongue squamous cell carcinoma (SCC). A 42-year-old Japanese woman was diagnosed with tongue SCC (T1N0M0, Stage I). Partial glossectomy with supraomohyoid neck dissection was performed under general anesthesia, and histopathological examinations revealed primary SCC of the tongue and neck metastasis of PTC in neck dissection specimens. A few months later, total thyroidectomy and left modified radical neck dissection were performed by thyroid surgeons. The histopathological diagnosis was PTC of both the thyroid glands. There was no evidence of tumor recurrence or distant metastasis at the 9-month follow-up.

Abstract
S-1 is an anticancer agent that is comprised of tegafur, gimeracil, and oteracil potassium, and is widely used in various carcinomas including oral squamous cell carcinoma (OSCC). Although an established prediction tool is not available, we aimed to develop prediction models for the sensitivity of primary OSCC cases to the preoperative administration of S-1. We performed DNA microarray analysis of 95 cases with OSCC. Using global gene expression data and the clinical data, we developed two different prediction models, namely, model 1 that comprised the complete response (CR) + the partial response (PR) versus stable disease (SD) + progressive disease (PD), and model 2 that comprised responders versus non-responders. Twelve and 18 genes were designated as feature genes (FGs) in models 1 and 2, respectively, and, of these, six genes were common to both models. The sensitivity was 96.3%, the specificity was 91.2%, and the accuracy was 92.6% for model 1, and the sensitivity was 95.6%, the specificity was 85.2%, and the accuracy was 92.6% for model 2. These models were validated using receiver operating characteristic analysis, and the areas under the curves were 0.967 and 0.949 in models 1 and 2, respectively. The data led to the development of models that can reliably predict the sensitivity of patients with OSCC to the preoperative administration of S-1. The mechanism that regulates S-1 sensitivity remains unclear; however, the prediction models developed provide hope that further functional investigations into the FGs will lead to a greater understanding of drug resistance.

Abstract
D-dimer levels are reported to relate with tumor stage, prognosis, and lymph node involvement, as well as overall survival (OS) in patients with solid tumors. The purpose of this study was to investigate association between the value of D-dimer and the prognosis of oral cancer (OC). We designed a retrospective cohort study and enrolled a sample of patients who were diagnosed with OC and treated with surgery and/or radiotherapy. The predictor was the D-dimer and outcome variable was OS. Other variables included age, neutrocyte count, neutrophil lymphocyte ratio (NLR), C-reactive protein (CRP), and management. Differences in OS rate were analyzed by log-rank test. A Cox proportional hazards model was used to adjust for the effects of potential confounders. Differences with a P value less than 0.05 were considered statistically significant. In 88 patients with OC, D-dimer median value for the predicting OS was 0.7 µg/mL. There was a significant difference in OS when patients were stratified according to D-dimer, with an OS rate of 77.8% for patients with low D-dimer (<0.7), and 57.3% with high D-dimer (≥0.7) (p = 0.035). Univariate analyses revealed close correlations between OS and age, neutrocyte count, NLR, CRP, and D-dimer (<0.7 and ≥0.7). Cox multivariate analysis identified management (mainly surgery vs. radiotherapy) (HR 3.274, 95% CI 1.397–7.676; p = 0.006) as independent predictive factors for OS. There was a significant difference in OS when patients were stratified according to D-dimer with low (<0.7) and high D-dimer (≥0.7) (p = 0.035). Though, as a predictive factor, management was associated with OS.

Abstract
The technique of covering a mucosal defect with fibrin glue and a polyglycolic acid sheet (MCFP) for the resection of mucosa is applied in oral cancers. The MCFP technique for partial glossectomy provides faster relief from postoperative pain and the prevention of scar contracture, unlike primary closure. However, it has a major complication of postoperative bleeding. This study sought to compare postoperative bleeding between the MCFP technique and primary closure. We designed a retrospective study with a cohort of 57 patients who underwent partial glossectomy with the MCFP technique or primary closure. Our primary predictor variable was the wound closure procedure (primary closure or the MCFP technique). The primary outcome variable was postoperative bleeding, and the other variables were patient characteristics, excision area and depth, tooth contact for the wound, and antithrombotic therapy. Statistical evaluation was performed with Pearson’s chi-squared test, Welch’s t-test, and multiple logistic regression. P < 0.05 was considered statistically significant. The MCFP technique was selected for cases with a large excision area (1433 vs. 963 mm2, P = 0.029). Total postoperative bleeding occurred in 10 of 57 patients (MCFP technique: 7 of 37 cases; primary closure: 3 of 20 cases). There was no significant difference in bleeding between the two groups (P = 0.71). Postoperative bleeding was significant in patients with antithrombotic therapy (MCFP: 40% vs. primary closure: 2%, P = 0.0024). Postoperative bleeding timing was significantly different in the MCFP technique (6.4 days) from that of primary closure (1 day; P = 0.0076). Postoperative bleeding was not associated with the MCFP technique or primary closure. However, postoperative bleeding with the MCFP technique occurred later than that with primary closure. The MCFP technique is not recommended for patients on antithrombotic therapy.

Abstract
PURPOSE The intraoral stent (IOS) is an individualized mouth opening device that can be used during radiotherapy (RT) for head and neck cancer to prevent unnecessary irradiation to normal tissues. The purpose of the present study was to compare the severity of oral mucositis (OM) between patients using and not using an IOS during RT for maxillary and nasal cavity cancer. PATIENTS AND METHODS We designed and implemented a retrospective cohort study. The study sample included patients with maxillary and nasal cavity cancer who had undergone RT. The primary predictor variable was IOS application, and the outcome variable was the grade of OM. RESULTS The IOS group included 18 patients with an IOS and the control group, 16 patients without an IOS. The parameters of the dose-volume histogram included the median dosage covering 1 mL (D1mL) for the tongue and the mean dosage. The D1mL (36.2 vs 65.4 Gy) and mean dosage (4.9 Gy vs 25.9 Gy) were both significantly lower in the IOS group than in the control group (P < .005). The incidence of OM using the National Cancer Institute Common Terminology Criteria for Adverse Events, version 4.0, were significantly different between the oral stomatitis grade and the use of an IOS (P = .028). A significant difference was found in opioid use between the IOS and control groups (P = .009). CONCLUSIONS The use of an IOS decreased the radiation dosage to the tongue, the grade of OM, and opioid usage during RT.

Abstract
Objective Reconstruction plates are used to treat patients with a segmental mandibular defect after oral cancer surgery. Reconstruction plate failure analysis has rarely focused on occlusion, which conducts a mechanical force to the mandible and the plate. To determine the prognostic factors, we retrospectively evaluated patients who underwent reconstruction of a mandibular segmental defect with a reconstruction plate and assessed the number of residual paired teeth. Material and Methods From among 390 patients with oral cancer who visited University of Tsukuba Hospital (Tsukuba, Japan) between 2007 and 2017, we selected and analyzed the data of 37 patients who underwent segmental resection of the mandible and reconstruction with reconstruction plates. Prognostic factors evaluated were patient age, sex, TNM classification, plate manufacturer, treatment with radiotherapy or chemotherapy, whether the patient had diabetes or smoked, and whether the patient had a small number of residual paired teeth, plate length, and use of a fibular‐free flap. Among these 37 patients, eight reconstruction plates had intraoral or extraoral exposure and were removed in 5 years. Results Kaplan–Meier and log‐rank analyses revealed that the prognosis for the 5‐year plate exposure‐free rate was significantly poorer for patients with a small number of residual teeth than for patients with no teeth or those with a large number of residual teeth (.01). Univariate Cox regression analysis revealed that a small number of residual teeth was a significant prognostic factor in the loss of a reconstruction plate (hazard ratio: 5.63; 95% confidence interval [1.10, 25.85]; .04). Conclusions A small number of residual teeth after the segmental resection of oral cancer is significantly involved in reconstruction plate survival and may be important in predicting reconstruction plate prognosis.

Abstract
Pulmonary nodules are frequently considered to be a metastatic disease or primary lung tumors in oral cancer patients. We present a case of pulmonary cryptococcosis in a 68-year-old man with oral and lung cancer. This lung cancer was treated with thoracoscopic resection of the right inferior lobe and mediastinal lymph node dissection. Lower gingival cancer was treated with a mandibulectomy, neck dissection, and reconstruction after chemoradiotherapy. A 20 mm cavitary nodule appeared at the left lung S6 one-month after surgery, during post-operative computed tomography. Thoracoscopic partial resection of the left inferior lobe was performed under the suspicion of lung metastasis. Pathology results revealed a pseudo-epithelial granuloma with necrosis and many yeast-shaped fungi with capsules. A pathological diagnosis of Cryptococcus infection was made. The patient was prescribed the antifungal agent fosfluconazole, which was administered intravenously for 1 week and intraoral fluconazole for 12 months. No recurrence of the Cryptococcus infection has been noted after 1.5 years.

Abstract
Objective Oral leukoplakia is keratinized lesions in the buccal mucosa, tongue, and gingiva. It is the most common oral precancerous lesion; oxidative stresses and irrelevant autophagy have been reported to be the cause of oncogenesis. p62, a cytoplasmic protein induced by oxidative stress, is an adaptor protein involved in the formation of protein aggregates and induction and inhibition of autophagy. The inhibition of autophagy induces p62 overexpression and promotes oncogenesis via the oncogenic signaling pathway. The aim of the present study was to elucidate the involvement of intracellular expression of p62 in oral leukoplakia and to address its potential clinical implementation as a biomarker to predict malignant transformation. Material and Methods Fifty samples from subjects with confirmed oral leukoplakia were evaluated by immunohistochemical staining for the expression of p62, 8-hydroxy-2'-deoxyguanosine (8-OHdG), Ki67, and p53. Univariate and multivariate logistic regression analyses were performed to evaluate the association between p62, 8-OHdG, Ki67, and p53 and clinical characteristics, including epithelial dysplasia. Results Significant associations were observed between p62 expression in the nucleus, p62 aggregation, and epithelial dysplasia (adjusted odds ratio [OR] = 5.75; 95% confidence interval [CI]: [1.28, 26.2]; .024 and OR = 6.16; 95% CI: [1.01, 37.4]; .048, respectively). The expression of p62 in the cytoplasm and the levels of 8-OHdG, Ki67, and p53 were not significantly associated with epithelial dysplasia. A significant relationship was found between p62 expression in the nucleus and p53 expression (OR = 3.94; 95% CI: [1.14, 13.6]; .031). Conclusions The results suggested that p62 expression in the nucleus and p62 aggregation can be potential markers to predict the malignant transformation of oral leukoplakia.

Abstract
Ameloblastic carcinoma (AC) is a rare malignant odontogenic tumor that combines the histologic features of ameloblastoma with those of cytologic atypia. The standard treatment for this lesion is wide local excision. Proton beam therapy (PBT) can deliver high irradiation doses to the target and avoid irradiation to surrounding normal tissues, but no reports of PBT for AC have been published thus far. This report describes the case of a 70-year-old woman with a pathologic diagnosis of maxillary AC who refused surgical resection and received hypofractionated PBT at a total dose of 69 Gy in 23 fractions. She has been alive for more than 5 years after PBT without any evidence of recurrence and side effects. This is the first reported case of successful treatment after curative radiation therapy for maxillary AC.

Abstract
Background and purpose Periodontal disease is closely related to lifestyle-related diseases and obesity. It is widely known that moderate exercise habits lead to improvement in lifestyle-related diseases and obesity. However, little research has been undertaken into how exercise habits affect periodontal disease. The purpose of this study was to examine the effect of exercise habits on periodontal diseases and metabolic pathology. Methods We conducted a prospective intervention research for 12 weeks. The subjects were 71 obese men who participated in an exercise and/or dietary intervention program. Fifty subjects were assigned to exercise interventions (exercise intervention group) and 21 subjects were assigned to dietary interventions (dietary intervention group). This research was conducted before and after each intervention program. Results In the exercise intervention group, the number of teeth with a probing pocket depth (PPD) ≥4 mm significantly decreased from 14.4% to 5.6% (P<0.001), and the number of teeth with bleeding on probing (BOP) significantly decreased from 39.8% to 14.4% (P<0.001). The copy counts of Tannerella forsythia and Treponema denticola decreased significantly (P=0.001). A positive correlation was found between the change in the copy count of T. denticola and the number of teeth with PPD ≥4 mm (P=0.003) and the number of teeth with BOP (P=0.010). A positive correlation was also found between the change in the copy count of T. denticola and body weight (P=0.008), low-density lipoprotein cholesterol (P=0.049), and fasting insulin (P=0.041). However, in the dietary intervention group the copy count of T. denticola decreased significantly (P=0.007) and there was no correlation between the number of periodontal disease-causing bacteria and PPD and BOP. Conclusion Our results are the first to show that exercise might contribute to improvements in periodontal disease.

Abstract
MicroRNAs (miRNAs or miRs) play important roles in carcinogenesis. The miRNA, miR-205-5p, has been reported to suppress the growth of various types of tumor; however, its functional contribution to oral squamous cell carcinoma (OSCC) is not yet clear. Thus, this study was conducted to determine the miRNA expression signatures in OSCC and to investigate the functional role of miR‑205‑5p in OSCC cells. We measured miR‑205‑5p expression by RT-qPCR, and examined the function of miR‑205‑5p by transfecting a miR‑205‑5p mimic or inhibitor into OSCC cells and measuring cell proliferation, migration and invasiveness. Genes targeted by miR‑205‑5p were identified using the TargetScan database and verified by western blot analysis, luciferase reporter assay and ELISA. We found that miR‑205‑5p was significantly downregulated in OSCC cell lines and tissue specimens. Following transfection of miR‑205‑5p mimic or inhibitor into the cancer cell lines, miR‑205‑5p overexpression significantly suppressed cancer cell migration and invasion. We further demonstrated that miR‑205‑5p directly targeted and regulated the tissue inhibitor of metalloproteinases‑2 (TIMP‑2) gene. The silencing of TIMP‑2 suppressed cancer cell invasion and the activation of pro‑matrix metalloproteinase‑2 (pro‑MMP‑2). These results suggest that TIMP‑2 promotes tumor progression, and that miR‑205‑5p directly regulates TIMP‑2, thereby suppressing pro‑MMP‑2 activation and inhibiting OSCC cell invasiveness. Our data describing the pathways regulated by miR‑205‑5p provide new insight into the mechanisms responsible for OSCC development and metastasis.

Abstract
Oral squamous cell carcinoma (OSCC) is the sixth most common cancer worldwide, and is associated with poor prognosis. Autophagy is a programmed cell survival mechanism involved in physiologic processes and various diseases including cancer. However, the relationship between autophagy and cancer is controversial. Several studies have claimed that the expression of autophagy-related proteins, namely microtubule-associated protein light chain3 (LC3) and p62/SQSTM1 (p62), is associated with poor prognosis in OSCC. In this study, we evaluated the expression of the autophagy-related markers LC3A/B and p62 by immunohistochemistry in 71 OSCC patient samples, especially focusing on surgical margins. Results were correlated with clinical characteristics. The expression of LC3A and LC3B was correlated with tumor recurrence and poor overall survival based on multivariate analysis, whereas the expression of p62 was correlated with only tumor recurrence and not prognosis. Thus, we suggest that the expression of autophagy-related markers at the surgical margins might be an indicator of local recurrence and poor prognosis in human OSCC. These results will aid in the development of new therapeutics and diagnostics for OSCC.

Abstract
BACKGROUND Abnormal miRNA expression was recently implicated in the metastasis of oral squamous cell carcinoma (OSCC) and with a poor prognosis. The initiation of the invasion-metastasis cascade involves epithelial-mesenchymal transition (EMT). Our aim was to clarify how miRNA, especially miR-155-5p misexpression contributes to OSCC metastasis through EMT. METHODS We collected tumor samples from 73 subjects with OSCC. The samples were analyzed by quantitative reverse-transcription polymerase chain reaction (qRT-PCR), and correlations between miR-155-5p levels and clinical characteristics were investigated. OSCC cell lines were analyzed by miRNA microarray and by transfection with a miR-155-5p mimic or inhibitor, followed by proliferation and wound-healing migration assays. qRT-PCR analyses of EMT makers in cells transfected with miR-155-5p inhibitor were performed. RESULTS We found high miR-155-5p expression in tissue samples from subjects with OSCC that had metastasized to cervical lymph nodes. HSC-3 cells also strongly expressed miR-155-5p. The epithelial marker E-cadherin was strongly expressed in HSC-3 cells transfected with miR-155-5p inhibitor, and we observed elevated SOCS1 and decreased STAT3 expression in these cells. CONCLUSIONS Our results suggest that miR-155-5p causes OSCC to metastasize, and could serve as a novel therapeutic target for OSCC.

Abstract
Background Recently, medical rapid prototyping (MRP) models, fabricated with computer-aided design and computer-aided manufacture (CAD/CAM) techniques, have been applied to reconstructive surgery in the treatment of head and neck cancers. Here, we tested the use of preoperatively manufactured reconstruction plates, which were produced using MRP models. The clinical efficacy and esthetic outcome of using these products in mandibular reconstruction was evaluated. Methods A series of 28 patients with malignant oral tumors underwent unilateral segmental resection of the mandible and simultaneous mandibular reconstruction. Twelve patients were treated with prebent reconstruction plates that were molded to MRP mandibular models designed with CAD/CAM techniques and fabricated on a combined powder bed and inkjet head three-dimensional printer. The remaining 16 patients were treated using conventional reconstruction methods. The surgical and esthetic outcomes of the two groups were compared by imaging analysis using post-operative panoramic tomography. Results The mandibular symmetry in patients receiving the MRP-model-based prebent plates was significantly better than that in patients receiving conventional reconstructive surgery. Conclusions Patients with head and neck cancer undergoing reconstructive surgery using a prebent reconstruction plate fabricated according to an MRP mandibular model showed improved mandibular contour compared to patients undergoing conventional mandibular reconstruction. Thus, use of this new technology for mandibular reconstruction results in an improved esthetic outcome with the potential for improved quality of life for patients.

Abstract
PURPOSE In gingival squamous cell carcinoma (GSCC), the association between survival and previous dental extraction (DE) is controversial. The purpose of this study was to investigate the prognosis for patients in whom GSCC was detected after DE was performed. PATIENTS AND METHODS DE for GSCC tumor symptoms was performed in 19 patients before diagnosis (DE group) and not in 58 patients (non-DE group). The clinical features, characteristics, and prognosis were evaluated statistically between the 2 groups. RESULTS The interval from DE to the first hospital visit was 1.1 to 97 weeks (median, 7.3 weeks). There was no significant difference in tumor status, node status, local recurrence, pathologically positive lymph nodes, or distant metastasis between the DE and non-DE groups. Bone invasion was observed radiographically in 6 patients with mandibular GSCC in the DE group (100%) and 13 in the non-DE group (68.4%). There was a significant difference in bone invasion between the DE and non-DE groups (P < .01). Segmental mandibulectomy was performed in 11 patients (84.6%) in the DE group and 21 patients (61.8%) in the non-DE group. Extent of resection tended to be larger for the DE group. The 5-year overall survival rate was 84.6% for the DE group and 65.8% for patients with mandibular GSCC in the non-DE group. For maxillary GSCC, the survival rates differed significantly between groups (33.3% in DE group and 73.7% in non-DE group). CONCLUSIONS For mandibular GSCC, the resection field was appropriate for the extent of bone invasion after DE and the prognosis was similar to that in the non-DE group. For maxillary GSCC, a broad surgical field is suggested because of the potential for rapid spread in cancellous bony trabeculae.

Abstract
While circulating tumor-derived molecules have been identified in a variety of malignant tumors, it is sometimes difficult to detect the molecular targets due to the lower serum concentration. We report that evaluation of circulating tumor-derived mitochondrial DNA (mtDNA) seems to have novel efficiency for detecting tumoral micrometastasis. In murine xenografting human oral cancer cells, human mtDNAs could be quantitatively detected from multiple organs and blood samples whereas human nucleic DNAs could not. We also determined if this mtDNA blood test was relevant for patients with oral cancer with no histologic evidence of tumoral cells in their surgical margins. For this, mtDNA from normal and tumorous tissues and serum mtDNA obtained pre and postoperatively was examined at three different regions including the displacement loop, 12S-rRNA, and 16S-rRNA. All recurring patients had significantly higher amounts of mutant mtDNAs in the tumoral tissues compared with the non-recurring group. More importantly, on the blood test with the cut-off point by receiver operating characteristic (ROC) curve analysis, while the vast majority of serum mtDNA samples obtained postoperatively in the recurring cases maintained significantly higher amounts of mutant mtDNAs, the non-recurring cases did not, and they showed good prognosis. This is the first report of this approach for managing patients after resection of oral tumors, and may have substantial diagnostic potential for other tumoral types.
