Abstract
Oncocytoma arising from the parotid gland and extending into the parapharyngeal space (PPS) has not been previously reported. A 64-year-old woman presented with a large slowly growing mass extending from the parotid to the submandibular area, expanding medially to displace the pharynx across the midline. Core-needle biopsy revealed an oncocytoma in the PPS measuring 120 × 88 × 60 mm in size. Although the tumor was of an unprecedentedly large size and extended into multiple spaces, it could be removed via a cervical-parotid approach without osteotomy. The resected tumor was again diagnosed as oncocytoma. A postoperative complication was weakness of the ipsilateral facial nerve, which almost completely resolved in 6 months. No recurrence has been noted on 1 y follow-up. We were able to resect an extremely large oncocytoma arising from the parotid gland without osteotomy.

Abstract
BACKGROUND Salivary duct carcinoma (SDC) is a high-grade adenocarcinoma with a 5-year survival rate of 40%. Although drug therapy has improved patients' prognosis, the impact of brain metastasis (BM) remains poorly understood. We aimed to retrospectively examine the incidence of BM in patients with SDC (n = 464) and develop a tool to estimate their prognoses. METHODS We retrospectively examined 464 patients with SDC enrolled in a multicenter study. We investigated the incidence of BM, overall survival (OS) rates, and factors affecting prognosis in patients with BM. We also developed an SDC-graded prognostic assessment (GPA) score for disease prognostication. RESULTS Sixty-five (14%) patients had BM. The median OS (mOS) was 13.1 months. On univariate and multivariate analyses, factors such as Eastern Cooperative Oncology Group Performance Status >1, human epidermal growth factor receptor 2-negative status, and locoregional uncontrolled disease were associated with poor OS. SDC-GPA scores according to the prognostic factors were 0, 1, 2, and 3 points, and mOS estimates were 50.5, 16.1, 3.9, and 1.2 months, respectively (p < 0.001). CONCLUSION The SDC-GPA score emerged as a useful prognostication tool for patients with BM.

Abstract
There is no standardized technique for lip reconstruction because the structure and functions of the lip are diverse. We developed a new lip reconstructive approach using a bilateral oblique mucosal V-Y advancement flap. We present the case of a 76-year-old woman with severe dementia, referred to our institute for a tumor on her lower lip. She was diagnosed with lip squamous cell carcinoma (cT2N0M0). The tumor measured 25 × 20 mm. It was resected with a surgical safety margin of 6 mm. Bilateral triangular flaps were fashioned obliquely on the rear lateral side of the defect extending from the labial to the buccal mucosa and used to repair the defect. The operation time was 66 min. She was discharged on the fourth postoperative day without any complications. Speech and food intake functions have been preserved and she has been followed up for 26 months with no recurrence. The lip closing and color match has been adequate despite a slight thinning of the lip. This technique offered a major benefit of short operation and hospitalization time because it was a simple, less-invasive, one-step procedure. This is a practical procedure, suitable for vulnerable patients of advanced age or with comorbidities.

Abstract
Salivary duct carcinoma (SDC) is an aggressive type of salivary gland carcinoma. Recently, immunotherapies targeting immune checkpoints, including PD1, PD-L1, CTLA4, and LAG3, have had a considerable prognostic impact on various malignant tumors. The implementation of such immune checkpoint inhibitor (ICI) therapies has also been attempted in cases of salivary gland carcinoma. The tumor immune microenvironment (TIME) is implicated in tumorigenesis and tumor progression and is closely associated with the response to ICI therapies. However, the TIME in SDC has not been fully explored. We examined the immunohistochemical expression of CD8, FOXP3, PD1, PD-L1, CTLA4, LAG3, and mismatch repair (MMR) proteins, tumor-infiltrating lymphocytes (TILs), and microsatellite instability (MSI) status in 175 cases of SDC. The associations between these TIME-related markers and the clinicopathological factors and prognosis were evaluated. An elevated expression of CD8, FOXP3, PD1, CTLA4, and LAG3 was associated with more aggressive histological features and an advanced N and/or M classification, elevated Ki-67 index, and poor prognosis. Furthermore, cases with a high PD-L1 expression exhibited more aggressive histological features and adverse clinical outcomes than those with a low expression. Alternatively, there was no significant correlation between TILs and clinicopathological factors. No SDC cases with an MSI-high status or MMR deficiency were found. The coexistence of both an immunostimulatory and immunosuppressive TIME in aggressive SDC might play a role in the presence of T-cell exhaustion. The contribution of multiple immune escape pathways, including regulatory T cells and immune checkpoints, may provide a rationale for ICI therapy, including combined PD1/CTLA4 blockade therapy.

Abstract
BACKGROUND/AIM Pembrolizumab exhibits anticancer efficacy in platinum-sensitive or platinum-unfit patients with recurrent/metastatic squamous cell carcinoma of the head and neck (R/M SCCHN). However, no large-scale retrospective real-world data are available. This retrospective study aimed to examine the efficacy and safety of pembrolizumab in multiple facilities. PATIENTS AND METHODS Data of 167 patients with R/M SCCHN treated with pembrolizumab between December 2019 and February 2022 were analyzed. The endpoint was overall survival (OS), progression-free survival (PFS), and immune-related adverse events (irAEs). OS and PFS were analyzed comparatively with and without irAEs, and complete response (CR) or partial response (PR), and stable disease (SD) or progressive disease (PD) were compared. RESULTS One hundred thirty-five patients received pembrolizumab alone, whereas the others received pembrolizumab with chemotherapy. For the pembrolizumab only group, the median OS and PFS were 22.7 and 5.1 months, respectively. There were significant differences in OS and PFS between CR or PR and SD or PD (p<0.01, p<0.01, respectively). For pembrolizumab with chemotherapy, the OS was not reached and median PFS was 7.0 months. There was a significant difference in PFS between CR or PR and SD or PD (p<0.01). There was a significant difference in PFS between patients with and without irAEs (p=0.02). CONCLUSION The real-world therapeutic effect of pembrolizumab for R/M SCCHN was comparable to that observed in the KEYNOTE048 trial. In addition, irAEs and best overall response were considered as prognostic factors.

Abstract
AIM Fluorescence imaging (FI) using indocyanine green (ICG) is a noteworthy alternative technique for sentinel lymph node (SLN) detection without radiation exposure in oral cavity and oropharynx cancer. However, conventional FI is monochrome, so the visibility is limited. This study assessed whether color FI using the HyperEye Medical System (HEMS) is feasible as an alternative for SLN detection. METHODS Patients with previously untreated cT1-2N0 oral or oropharyngeal cancer who were to undergo primary tumor resection and elective neck dissection (END) in our hospital were enrolled from November 2012 to March 2016. The patients underwent SLN detection for biopsy via the HEMS following the injection of ICG solution around the primary lesion before neck dissection. The visibility and the diagnostic accuracy of the imaging were evaluated. RESULTS SLNs were visualized in all eight cases; however, transcutaneous fluorescence detection was not observed in all cases. Utilizing color mode imaging simplified harvest by clearly discriminating SLNs from surrounding structures, while the monochrome mode proved to be more sensitive for detection. Two cases showed occult metastases on both sentinel and regional nodes. The identification and false negative rates were 100% and 0%, respectively. There were no complications incurred due to this method. CONCLUSION Our results suggest that color FI with the HEMS allows for the accurate and safe harvest of SLNs with a preparatory skin incision. Although there is room for improvement of sensitivity, this easy-to-handle procedure might provide the potential to expand the role of the ICG method for SLN detection in head and neck cancer.

Abstract
PURPOSE Due to difficulties in breath holding, patients who undergo total laryngectomy may be prone to the development of chronic constipation. However, few reports have described chronic constipation in laryngectomized patients, and no report has described prevalence in patients who have undergone total pharyngolaryngectomy. METHODS We conducted a cross-sectional study to investigate the prevalence of chronic constipation after laryngectomy and evaluated the relationship between patient characteristics and chronic constipation. Information on patient characteristics and the details of surgery were obtained from medical records and an original questionnaire survey in 50 patients. RESULTS The prevalence of chronic constipation after laryngectomy was high, at 36%, with 18 cases. Patients who received total laryngectomy were significantly more likely to have chronic constipation than those who received total pharyngolaryngectomy (47.1% vs 12.5%, P = 0.026), who had a similar prevalence to the general public. Furthermore, the period from surgery to survey was significantly shorter in the constipation group than in the no constipation group (P = 0.043). CONCLUSIONS The prevalence of chronic constipation in patients who had undergone laryngectomy for head and neck cancer was high, particularly in patients who received total laryngectomy and in those with only a short period since surgery.

Abstract
Background The efficacy and safety of human epidermal growth factor receptor 2 (HER2)-targeted therapy and androgen deprivation therapy (ADT) for locally advanced or recurrent or metastatic (LA/RM) salivary duct carcinoma (SDC) have been reported in prospective studies. However, the survival benefit of these therapies to conventional therapy remains controversial, and whether HER2-targeted therapy or ADT should be chosen in HER2- and androgen receptor (AR)-positive SDC patients remains unknown. Methods Overall, 323 LA/RM SDC patients treated at seven institutions between August 1992 and June 2020 were retrospectively enrolled. The primary aim was to analyze the effect of HER2-targeted therapy and ADT on overall survival from the diagnosis of LA/RM disease to death from any cause (OS1). The secondary indicators included the overall response rate (ORR), clinical benefit rate (CBR), overall survival from therapy initiation for LA/RM disease (OS2), progression-free survival (PFS), time to second progression (PFS2), duration of response (DoR), and duration of clinical benefit (DoCB) of HER2-targeted therapy or ADT as first-line therapy for HER2-positive/AR-positive SDC. Results Patients treated with HER2-targeted therapy or ADT had longer OS1 than those treated without these therapies (Median OS1: historical control, 21.6 months; HER2-targeted therapy, 50.6 months; ADT, 32.8 months; HER2-targeted therapy followed by ADT, 42.4 months; and ADT followed by HER2-targeted therapy, 45.2 months, p < 0.001). Among HER2-positive/AR-positive SDC patients, although HER2-targeted therapy had better ORR, CBR, and PFS than those of ADT as first-line therapy, we found no significant differences between HER2-targeted therapy and ADT regarding OS2, PFS2, DoR, and DoCB. Conclusion Patients treated with HER2-targeted therapy and ADT showed longer survival in LA/RM SDC. HER2-targeted therapy can be recommended prior to ADT for HER2-positive/AR-positive SDC. It is warranted to establish a biomarker that could predict the efficacy of clinical benefit or better response in ADT.

Abstract
BACKGROUND/AIM In patients with squamous cell carcinoma of the head and neck (SCCHN), delayed surgery can result in poorer postoperative function and prognosis due to the growth of the tumor and extended surgery. Further, delay may even make the tumor unresectable. To prevent tumor growth during the waiting period before surgery, S-1 has been administrated preoperatively at several facilities in Japan. To date, however, the safety and efficacy of preoperative S-1 remain unclear. PATIENTS AND METHODS We conducted a retrospective cohort study of 118 patients with SCCHN treated with S-1 before radical surgery at 2 institutions in Japan. We evaluated the safety of S-1 therapy, which was evaluated by the incidence of grade 3 or greater adverse events (AEs). The rate of achievement of non-growth of tumors was also calculated. RESULTS Regarding safety, 125 AEs of all grades were recorded in 71 patients (60%). Of these, grade 3 AEs were detected in 3 patients (3%), and no grade 4 or 5 AEs occurred. The nongrowth rate of primary lesions and lymph node metastases was 89% and 85%, respectively. CONCLUSION Preoperative S-1 therapy might be useful, with acceptable toxicity, on an outpatient basis in patients with SCCHN.

Abstract
This study compared the incidence of perioperative complications and swallowing function between free jejunal flap reconstruction and cutaneous free tissue flap construction. We included 223 patients who underwent hypopharyngeal reconstruction using free flap. At discharge, +the free jejunal flap was associated with a Functional Oral Intake Scale (FOIS) score of 1-6 in 132 cases (70%) and a score of 7 in 56 cases (30%). Regarding the cutaneous free tissue flaps, FOIS scores of 1-6 were observed in 18 cases (51%), and a score of 7 was noted in 17 cases (49%). Donor site complications occurred in 12% of the patients who underwent free jejunal flap procedures and in none of the patients who underwent cutaneous free tissue flap procedures. We found that the free jejunal flap had a regular dietary intake rate in 56 patients (30%), whereas cutaneous free tissue flaps had a regular dietary intake rate in 17 patients (49%). Cutaneous free tissue flaps had a significantly higher regular dietary intake rate at discharge and a significantly lower incidence of donor site complications than free jejunal flaps. In conclusion, free-flap reconstruction may be a better method than free jejunal flap reconstruction for the treatment of hypopharyngeal cancer.

Abstract
ObjectiveSalivary duct carcinoma (SDC) is a highly aggressive and uncommon tumor arising not only de novo but also in pleomorphic adenoma. Androgen receptor (AR)- and HER2-targeted therapy have recently been introduced for SDC as promising treatment options; however, no predictive biomarkers have yet been established. EZH2 and H3K27me3 are closely linked to the development and progression of various cancers, and EZH2 is also expected to be a desirable therapeutic target. We therefore explored the clinicopathological and prognostic implications of EZH2 and H3K27me3 in a large cohort of SDC patients, focusing on their impact on the therapeutic efficacy of AR- or HER2-targeted therapy.Materials and MethodsThe EZH2 and H3K27me3 immunohistochemical expression and EZH2 Y646 gain-of-function mutation status were examined in 226 SDCs, and the relationship with the clinicopathological factors as well as clinical outcomes were evaluated within the three groups depending on the treatment: AR-targeted (combined androgen blockade with leuprorelin acetate and bicalutamide; 89 cases), HER2-targeted (trastuzumab and docetaxel; 42 cases), and conventional therapy (112 cases).ResultsEZH2 and H3K27me3 were variably immunoreactive in most SDCs. A positive correlation was found between the expression of EZH2 and H3K27me3. The EZH2 expression in the SDC component was significantly higher than that in the pre-existing pleomorphic adenoma component. EZH2 Y646 was not identified in any cases. EZH2-high cases more frequently had an advanced clinical stage and aggressive histological features than EZH2-low cases. An EZH2-high status in patients treated with AR-targeted therapy was associated with a significantly shorter progression-free and overall survival as well as a lower objective response rate and clinical benefit rate. In addition, a H3K27me3-high status in patients treated with AR-targeted therapy was related to a shorter overall survival. Conversely, there was no association between the EZH2 and H3K27me3 expression and the clinical outcomes in the conventional or HER2-targeted therapy groups.ConclusionsA high expression of EZH2 and H3K27me3 in SDC might be a predictor of a poor efficacy of AR-targeted therapy. Our data provide new insights into the role of EZH2 and H3K27me3 in therapeutic strategies for SDC.

Abstract
BACKGROUND/AIM Nivolumab, an anti-PD-1 inhibitor, has demonstrated efficacy in patients with several types of recurrent and metastatic (R/M) squamous cell carcinoma of the head and neck. We evaluated patients with R/M-NPC receiving nivolumab. PATIENTS AND METHODS Twelve patients with R/M-NPC were enrolled at 4 institutions. The primary endpoint was overall survival, and secondary endpoints were i) progression-free survival (PFS), ii) overall response rate (ORR), iii) disease control rate (DCR), and iv) treatment-related toxicity. RESULTS The 1-year survival rate was 75.8%, the median PFS was 2.8 months, and the 1-year PFS rate was 33.3%. The best therapeutic response was complete response in 2, stable disease in 3 and progressive disease in 7 patients. The ORR of all patients was 16.7% and the DCR was 41.7%. CONCLUSION Nivolumab is a useful and relatively safe second-line systemic therapy in patients with R/M-NPC, and even patients who do not respond to nivolumab may survive for a long time.

Abstract
BACKGROUND Parapharyngeal space tumors are rare. Among them, tumors in the prestyloid compartment are particularly suitable for surgery; however, there are no detailed reports of such surgery and their features remain unknown. METHODS We conducted a retrospective cohort study. For 67 surgical cases of benign tumors in this compartment, we examined the patient and tumor characteristics, fine-needle aspiration cytology (FNAC), and intraoperative details such as surgical approach, use of complete excision, and postoperative complications. RESULTS Pleomorphic adenomas (PAs) comprised 73.1% of the lesions. The diagnostic accuracy of FNAC to differentiate benign and malignant tumors was 97.7%. Of the treated lesions, 94.0% were removed via the cervical approach alone, including all PAs. The remaining 6.0% were resected via the cervical-parotid approach. The median operative time and bleeding volume were 89 min and 50 mL, respectively. Operative time using the cervical approach was significantly shorter (p = 0.021). All cases could be treated via complete surgical excision. Postoperative complications occurred in 32.8% of patients, with transient slight facial palsy being the most common. No fatal complications occurred and 92.5% of patients had no sequelae. There was no significant association between complications and surgical approach. CONCLUSION Based on diagnosis by FNAC, with a high accuracy rate, most benign prestyloid tumors, especially PAs, were resected using the cervical approach alone, with a shorter operative time and without severe complications.

Abstract
Although immune-checkpoint inhibitors (ICIs) are effective against various cancers, little is known regarding their role in salivary gland carcinoma (SGC) treatment. Therefore, we evaluated the efficacy and safety of nivolumab monotherapy in patients with recurrent and/or metastatic SGC. In this multicentre retrospective study, nivolumab (240 mg) was administered every 2 weeks. The overall response rate (ORR), progression-free survival (PFS), overall survival (OS), and safety were examined; the correlation between treatment outcomes and clinicopathological factors was analysed. Twenty-four patients were enrolled; the most common histopathology was salivary duct carcinoma. Eleven tumours were PD-L1-positive; no tumour was microsatellite instability-high. The ORR was 4.2%, and the median PFS and OS were 1.6 and 10.7 months, respectively. One patient continued nivolumab for 28 months without disease progression. One patient showed grade 4 increase in creatine phosphokinase levels and grade 3 myositis. Biomarker analysis revealed significantly increased OS in patients with performance status of 0; modified Glasgow prognostic score of 0; low neutrophil-to-lymphocyte ratio, lactate dehydrogenase, and C-reactive protein; and high lymphocyte-to-monocyte ratio and in patients who received systemic therapy following nivolumab. Although nivolumab's efficacy against SGC was limited, some patients achieved long-term disease control. Further studies are warranted on ICI use for SGC.

Abstract
AIM This study retrospectively investigated the efficacy and safety of nivolumab for patients with recurrent or metastatic head and neck squamous cell carcinoma (R/M HNSCC) classified using age <65 years as the cutoff. METHODS Overall, 88 patients with R/M HNSCC treated with nivolumab were classified into the young group (<65 years; n = 39) and elderly group (≥65 years; n = 49). Efficacy was evaluated using overall survival (OS), progression-free survival (PFS), overall response rate (ORR) and disease control rate (DCR). Safety was evaluated considering immune-related adverse events (irAEs). RESULTS The median OS was 9.7 and 8.6 months in the young and elderly groups, respectively. The 1-year OS rate was 42.0% and 29.4% in the young and elderly groups, respectively. The median PFS was 3.0 and 4.2 months in the young and elderly groups, respectively. The 1-year PFS rate was 30.0% and 27.9% in the young and elderly groups, respectively. In the young group, the ORR was 10.3% and DCR was 33.3%. In the elderly group, the ORR was 18.4% and DCR was 53.1%. There were no significant differences in OS, PFS, ORR, and DCR (P = 0.36, 0.53, 0.29 and 0.06, respectively). Interstitial lung disease (ILD) as an irAE occurred in the young group at a significantly higher rate (20.5% vs 4.1%; P = 0.02). CONCLUSIONS There were no significant differences in OS, PFS, ORR, and DCR between the young and elderly groups. DCR tended to be better in the elderly group (P = 0.06). ILD occurred at a significantly higher rate in the young group.

Abstract
Background Disseminated cryptococcosis is a well-characterized complication in immunocompromised patients with cryptococcal pneumonia or meningitis; however, isolated cryptococcal osteomyelitis is a rare entity that occurs in approximately 5% of patients with cryptococcosis. Cryptococcal osteomyelitis in the head and neck region is extremely rare. To the best of our knowledge, no cases of cryptococcal osteomyelitis affecting only the zygomatic bone have been reported to date. Case presentation A 78-year-old man without other comorbidities presented with progressive swelling of the right cheek along with pain and trismus. Clinical examination revealed a tender swelling in the right zygomatic region; the maximal mandibular opening was about 2 cm. Laboratory data showed mildly elevated inflammatory indices (C-reactive protein: 0.45 mg/dL; erythrocyte sedimentation rate: 35 mm/h). Computed tomography showed a 30-mm-diameter lesion at the right zygomatic arch. A part of the lesion has extended to the subcutaneous area of the cheeks with signs of bone destruction and surrounding contrast effects. Histopathological examination of fine-needle aspirate and needle biopsy showed cryptococcus. Furthermore, culture of the aspirate showed growth of Cryptococcus neoformans. No evidence of any other site involvement was observed. Therefore, the patient was diagnosed with isolated cryptococcal osteomyelitis and was initiated on fluconazole therapy. The treatment was effective, and all symptoms were resolved in 4 weeks. Fluconazole therapy was stopped after 6 months. There are no signs of recurrence as of 15-month follow-up. The patient has no cosmetic abnormalities or sequelae. Conclusions Fine-needle aspiration cytology, needle biopsy, and fungal culture were useful for definitive diagnosis. Immunocompetent patients with isolated osteomyelitis may be cured with oral fluconazole alone.

Abstract
Background There is increasing evidence that immunotherapy with nivolumab, an anti‐programmed death 1 monoclonal antibody, is effective in the treatment of recurrent or metastatic squamous cell carcinoma of the head and neck (R/M SCCHN). However, the predictive role of hematological inflammatory markers such as neutrophil‐to‐lymphocyte ratio (NLR) and the modified Glasgow prognostic score (mGPS) in patients with R/M SCCHN treated with nivolumab remains unclear. Methods We conducted a multi‐institutional cohort study to evaluate the impact of pretreatment NLR and mGPS on overall survival (OS) and progression‐free survival (PFS) in patients with R/M SCCHN treated with nivolumab in Japan. From 2012 to 2013, 102 patients were eligible, of whom 88 were finally included in the analysis. mGPS was calculated as follows: mGPS of 0, C‐reactive protein (CRP) ≤1.0 mg/dL; 1, CRP > 1.0 mg/dL; and 2, CRP > 1.0 mg/dL and albumin < 3.5 mg/dL. Optimal cutoff point of dichotomized NLR was calculated using the area under the receiver operating characteristic curve (AUROC). Hazard ratios (HRs) and 95% confidence intervals (95% CIs) were estimated by Cox proportional hazard models adjusted by potential confounders. Results Higher NLR was significantly associated with worse survival (1‐year OS: 45.3% vs 16.3%, log‐rank P‐value < .001, adjusted HR: 4.40 (95% CIs: 1.78‐10.88); one‐year PFS: 39.1% vs 9.0%, P‐value = .001, adjusted HR: 3.37 (95% CI: 1.64‐6.92)). In addition, high mGPS (=2) was significantly associated with worse survival compared to low mGPS (=0) (1‐year OS: 37.4% vs 26.1%, P‐value = .004, adjusted HR: 4.20 (95% CI:1.54‐11.49); 1‐year PFS: 41.5% vs 24.8%, P‐value = .007, adjusted HR: 2.01 (95% CI: 0.87‐4.68)). These associations were consistent with subgroup analyses stratified by potential confounders. Conclusions Pretreatment NLR and mGPS might be predictive markers of survival in patients with R/M SCCHN treated with nivolumab.

Abstract
Background: Few studies have demonstrated the utility of pharyngeal interposition graft (PIG) applying pectoralis major myocutaneous flap (PMMCF) by comparing pharyngocutaneous fistula (PCF) rates.Objective: The objective of this retrospective study was to clarify the utility of PIG applying PMMCF in reducing post-operative complications due to salvage total laryngectomy (STL).Material and methods: STL was performed in 59 patients with recurrent laryngeal cancer after radiotherapy, comprising 37 non-PMMCF patients and 22 PMMCF patients. The primary endpoint was PCF rate. Comparisons were made between two groups: a group with simple closure not using PMMCF (non-PMMCF group), and the other with PMMCF used in a PIG (PMMCF group).Results: PCF occurred in 15 of the 59 subjects (25.4%), including 13 of the 37 patients in the non-PMMCF group (35.1%) and 2 of the 22 patients in the PMMCF group (9.1%). PCF rate was significantly lower in the PMMCF group than in the non-PMMCF group (p = .033).Conclusions and significance: We demonstrated that PIG applying PMMCF significantly reduced the PCF rate due to STL. In the future, surgeons need to conduct research focused on additional innovations to reduce post-operative complications as much as possible.

Abstract
Background: No large-scale retrospective studies have examined the efficacy and safety of nivolumab. Objective: This retrospective study aimed to investigate the efficacy and safety of nivolumab administered to patients in multiple facilities. Material and methods: The primary endpoint was overall response rate (ORR) and secondary endpoints were progression-free survival (PFS) and overall survival (OS). For safety, adverse event occurrence rates by grade, deaths and severe adverse events were investigated. OS and PFS were also examined according to whether immune-related adverse events (irAEs) appeared. Statistical analysis was conducted using log-rank testing, with values of p < .05 considered significant. Results: Nivolumab was administered to 100 patients with a history of receiving platinum-based drugs. ORR was 13.5% and disease control rate was 49.0%. Median PFS was 3.7 months. Median OS was 9.6 months. For all grades, irAEs occurred in 30 patients. The 1-year survival rate in the subgroup without irAEs was 34.0%, compared to 52.6% with irAEs (p = .041). Conclusions and significance: The 1-year survival rate was better in patients who developed irAEs. This is a new finding for head and neck cancer. Appearance of irAEs could also be used as an indicator of expected therapeutic effect in head and neck cancer.

Abstract
Gut microbiome development affects infant health and postnatal physiology. The gut microbe assemblages of preterm infants have been reported to be different from that of healthy term infants. However, the patterns of ecosystem development and inter-individual differences remain poorly understood. We investigated hospitalised preterm infant gut microbiota development using 16S rRNA gene amplicons and the metabolic profiles of 268 stool samples obtained from 17 intensive care and 42 term infants to elucidate the dynamics and equilibria of the developing microbiota. Infant gut microbiota were predominated by Gram-positive cocci, Enterobacteriaceae or Bifidobacteriaceae, which showed sequential transitions to Bifidobacteriaceae-dominated microbiota. In neonatal intensive care unit preterm infants (NICU preterm infants), Staphylococcaceae abundance was higher immediately after birth than in healthy term infants, and Bifidobacteriaceae colonisation tended to be delayed. No specific NICU-cared infant enterotype-like cluster was observed, suggesting that the constrained environment only affected the pace of transition, but not infant gut microbiota equilibrium. Moreover, infants with Bifidobacteriaceae-dominated microbiota showed higher acetate concentrations and lower pH, which have been associated with host health. Our data provides an in-depth understanding of gut microbiota development in NICU preterm infants and complements earlier studies. Understanding the patterns and inter-individual differences of the preterm infant gut ecosystem is the first step towards controlling the risk of diseases in premature infants by targeting intestinal microbiota.

Abstract
BACKGROUND/AIM The aim of this study was to evaluate the efficacy and safety of carboplatin/docetaxel combination therapy in patients with locally advanced and/or recurrent/metastatic (LA/RM) salivary gland carcinoma (SGC). MATERIALS AND METHODS This was a retrospective analysis of 24 patients that included six patients with AR-positive salivary duct carcinoma (SDC) after progressive disease treated with combined androgen blockade (CAB). Carboplatin (AUC5) and docetaxel (70 mg/m2) were administered for six courses every three weeks. RESULTS The overall response rate was 42%, the median progression-free survival was 8.4 months, and the median overall survival was 26.4 months. Among the six patients with CAB-resistant SDC, two achieved a partial response and two long-term stable disease. Grade 3/4 neutropenia and anemia were observed in 20-30% of the patients; all adverse events were manageable. CONCLUSION Carboplatin/docetaxel combination therapy may be a chemotherapeutic option for patients with LA/RM SGC, and a valuable second-line chemotherapy for CAB-resistant, AR-positive SDC.

Abstract
PURPOSE Clinical evidence demonstrating the effectiveness of systemic therapy for advanced salivary duct carcinoma (SDC) is lacking because of the disease's rarity. We assessed the efficacy and toxicity of trastuzumab plus docetaxel in patients with locally advanced and/or recurrent or metastatic human epidermal growth factor receptor 2-positive SDC. PATIENTS AND METHODS This was a single-center, single-arm, open-label, phase II study in Japan. The patients received trastuzumab at a loading dose of 8 mg/kg, followed by 6 mg/kg every 3 weeks. Docetaxel 70 mg/m2 was administrated every 3 weeks. The primary end point was the overall response rate; the secondary end points included the clinical benefit rate, progression-free survival, overall survival, and toxicity. This study is registered with the University Hospital Medical Information Network Clinical Trials Registry (Identification No. UMIN000009437). RESULTS Fifty-seven eligible patients with SDC were enrolled. The overall response rate was 70.2% (95% CI, 56.6% to 81.6%), and the clinical benefit rate was 84.2% (95% CI, 72.1% to 92.5%). Median progression-free and overall survival times were 8.9 months (95% CI, 7.8 to 9.9 months) and 39.7 months (95% CI, not reached), respectively. The most frequent adverse event was anemia (52 patients [91%]), followed by a decreased WBC count (51 patients [89%]) and neutropenia (50 patients [88%]). The most frequently observed grade 4 adverse event was a decreased neutrophil count (34 patients [60%]). Grade 3 febrile neutropenia was reported in eight patients (14%). No grade 2 or greater adverse events of heart failure or left ventricular ejection fraction decline to less than 50% occurred. CONCLUSION Our data show encouraging efficacy of trastuzumab plus docetaxel therapy in patients with human epidermal growth factor receptor 2-positive SDC, with a manageable toxicity profile.

Abstract
OBJECTIVE Currently, many studies are being performed that focus on the efficacy and safety of the vessel sealing system (VSS) in various fields of surgery. However, in the field of oral cancer surgery, the efficacy and safety of VSS use have not been clarified. METHODS One hundred and fifty-one patients underwent oral cancer resection and reconstructive surgery. They were divided into two groups: Ligasure vessel sealing system (LVSS) group and conventional surgery (CS) as control. Intra-operative blood loss, operating time, and incidence of post-operative complications and recurrence were analyzed. RESULTS LVSS use significantly reduced intra-operative blood loss. The operating time was shortened only in mandibular gingiva cancer surgery. There were no differences between the two groups with regard to the incidence of post-operative complications and recurrence. CONCLUSIONS LVSS use was found to be effective and proved to be efficient and safe, and may be useful in oral cancer surgery.

Abstract
Background There is no standard first-line chemotherapy for recurrent/metastatic (RM) or unresectable locally advanced (LA) salivary gland carcinoma (SGC). Patients and methods We conducted a single institution, open-label, single arm, phase II trial of combined androgen blockade (CAB) for androgen receptor (AR)-positive SGC. Leuprorelin acetate was administered subcutaneously at a dose of 3.75 mg every 4 weeks. Bicalutamide was administered orally at a daily dose of 80 mg. Patients were treated until progressive disease or unacceptable toxicities. Results Thirty-six eligible patients were enrolled. Thirty-three patients had RM disease and three patients had LA disease. The pathological diagnoses were salivary duct carcinoma (34 patients, 94%) and adenocarcinoma, NOS (two patients, 6%). The best overall response rate was 41.7% [n = 15, 95% confidence interval (CI), 25.5%-59.2%], the clinical benefit rate was 75.0% (n = 27, 95% CI, 57.8%-87.9%). The median progression-free survival was 8.8 months (95% CI, 6.3-12.3 months) and the median overall survival was 30.5 months (95% CI, 16.8 months to not reached). Additional analyses between treatment outcomes and clinicopathological factors or biomarkers including AR positivity, human epidermal growth factor receptor 2 status, and its complex downstream signaling pathway gene mutations showed no statistically significant differences. Elevated grade 3 liver transaminases and increased serum creatinine were reported in two patients, respectively. Discontinuation of leuprorelin acetate or bicalutamide due to adverse event occurred in one patient. Conclusion This study suggests that CAB has equivalent efficacy and less toxicity for patients with AR-positive RM or unresectable LA SGC compared with conventional chemotherapy, which warrants further study.

Abstract
Gut microbiota affects the host’s metabolism, and it is suggested that there are differences in gut microbiota composition between patients with type 2 diabetes and healthy individuals. Additionally, dysbiosis may increase the concentration of lipopolysaccharides (LPS), causing metabolic endotoxemia, which induces impaired glucose tolerance. Several studies have reported relationships between metabolic diseases and the gut microbiota; and prebiotics, such as oligosaccharides, are commonly consumed to regulate gut microbiotas in healthy individuals. Galacto-oligosaccharides (GOS) are a major prebiotic, which specifically increase Bifidobacteriaceae abundance. Recent studies have reported that Bifidobacteriaceae improved metabolic endotoxemia or impaired glucose tolerance. However, there are few studies reporting the effects of GOS on patients with type 2 diabetes. In the current study, we compared clinical parameters, faecal gut microbiota, their associated metabolic products and their components such as LPS, and LPS-binding protein (LBP) produced by the host, between patients with diabetes and healthy controls. We then assessed the effects of GOS on glycaemic control, and gut microbiotas and metabolites in patients with type 2 diabetes in a double-blind controlled manner. LBP levels were significantly higher in patients with diabetes than those of healthy subjects, which was consistent with previous reports. The abundance of Bifidobacteriaceae and the diversity of intestinal microbiota were significantly lower in patients with diabetes than in healthy subjects. Interestingly, Bifidobacteriaceae was markedly restored in patients with diabetes after consumption of GOS, whereas LBP and glucose tolerance did not improve during this short-term trial period. In the present study, we demonstrated that GOS can ameliorate dysbiosis in patients with diabetes, and continuous intake of GOS may be a promising method for managing type 2 diabetes.

Abstract
Using preserved specimens, we studied the basic life history of the topotypic population of the unique Asian plethodontid salamander, Karsenia koreana. Of 51 individuals examined, 11 males and 13 females were judged as mature from the development of gonads. The ovarian eggs were large (diameter 3.7-4.8 mm) and yellow to orange in color, and the clutch size was about 8-10. These values approximate those of actually spawned eggs recently reported. Skeletochronological analyses revealed the average age of males (5.3 years) to be lower than females (7.3 years). The age at maturity and maximum observed longevity were four and nine years in males and five and 10 years in females, respectively. In the growth curves estimated by a von Bertalanffy growth model, the growth coefficient and asymptotic SVL did not differ between the sexes, although males (40.6 mm) were smaller than females (45.3 mm) in the average snout-vent length. The time and place of courtship behavior, oval development, hatching, and especially, whether the species shows aquatic larval stage or direct development, are important topics to be resolved in future.

Abstract
The objective of the study was to investigate whether an infant formula supplemented with galacto-oligosaccharides (GOS; OM55N) was able to stimulate the growth of indigenous bifidobacteria and to establish microbiota similar to that of breastfed infants. A randomised, double-blind, placebo-controlled trial was performed using 35 healthy term infants (31-54 days of age; 42±6 days) to determine whether infant formula with 0.3 g/dl GOS (OM55N) stimulated the growth of bifidobacteria in the infants’ guts. At the trial onset and 2 weeks after, the infants’ faecal samples were examined for microbiota composition (bacterial abundance and α-diversity) and faecal characteristics. Among the 35 infants, 5 were withdrawn and 8 were excluded from the final evaluation before breaking the blinding since the indigenous bifidobacteria were not detected at the trial onset. After 2 weeks, the abundance of Bifidobacteriaceae was significantly increased in the GOS feeding group compared to the control (+11.6±24.1% vs -3.9±13.0%; P=0.043). The Shannon index, which accounts for both abundance and evenness of the present species, was significantly decreased with GOS supplementation (-0.1±0.4 vs +0.4±0.4; P=0.014). Faecal characteristics such as pH and organic acids were similar in both groups, with no statistical differences. No adverse side effects related to the formula consumption were reported. Although the concentration of GOS was relatively low, the infant formula with GOS increased the abundance of bifidobacteria and resulted in a reduced α-diversity of the microbiota.

Abstract
A 12 × 12 pixel detector has been developed and used in a laboratory experiment for lost fast-ion diagnostics. With gamma rays in the MeV range originating from nuclear reactions (9)Be(α, nγ)(12)C, (9)Be(d, nγ)(12)C, and (12)C(d, pγ)(13)C, a high purity germanium (HPGe) detector measured a fine-energy-resolved spectrum of gamma rays. The HPGe detector enables the survey of background-gamma rays and Doppler-shifted photo peak shapes. In the experiments, the pixel detector produces a gamma-ray image reconstructed from the energy spectrum obtained from total photon counts of irradiation passing through the detector's lead collimator. From gamma-ray image, diagnostics are able to produce an analysis of the fast ion loss onto the first wall in principle.

Abstract
We constructed an instrument for time-resolved photoemission electron microscopy (TR-PEEM) utilizing femtosecond (fs) laser pulses to visualize the dynamics of photogenerated electrons in semiconductors on ultrasmall and ultrafast scales. The spatial distribution of the excited electrons and their relaxation and/or recombination processes were imaged by the proposed TR-PEEM method with a spatial resolution about 100 nm and an ultrafast temporal resolution defined by the cross-correlation of the fs laser pulses (240 fs). A direct observation of the dynamical behavior of electrons on higher resistivity samples, such as semiconductors, by TR-PEEM has still been facing difficulties because of space and/or sample charging effects originating from the high photon flux of the ultrashort pulsed laser utilized for the photoemission process. Here, a regenerative amplified fs laser with a widely tunable repetition rate has been utilized, and with careful optimization of laser parameters, such as fluence and repetition rate, and consideration for carrier lifetimes, the electron dynamics in semiconductors were visualized. For demonstrating our newly developed TR-PEEM method, the photogenerated carrier lifetimes around a nanoscale defect on a GaAs surface were observed. The obtained lifetimes were on a sub-picosecond time scale, which is much shorter than the lifetimes of carriers observed in the non-defective surrounding regions. Our findings are consistent with the fact that structural defects induce mid-gap states in the forbidden band, and that the electrons captured in these states promptly relax into the ground state.

Abstract
UNLABELLED Aims/Introduction: Endothelial progenitor cells (EPC) play a critical role in adult vasculogenesis and vascular repair. Previous studies have described the dysfunction of EPC in diabetic patients, but the precise mechanism is still unclear. To elucidate the dysfunction of EPC in diabetic patients, we investigated the functions and intracellular signaling of EPC under normal or high glucose conditions. We also examined the number of EPC in the peripheral blood of Japanese type 2 diabetic patients. MATERIALS AND METHODS EPC were cultured with normal or high glucose. Subsequently, the proliferation and the apoptosis of EPC were assessed in the presence or absence of vascular endothelial growth factor (VEGF). The phosphorylation of Akt was assessed by western blot analyses. We compared the number of CD34(+)CD45(low) progenitor cells, which is considered as a marker of EPC in non-diabetic and type 2 diabetic subjects, using flow cytometry. RESULTS High glucose decreased the proliferation of EPC and increased the number of apoptotic cells. VEGF significantly increased the proliferation and suppressed the apoptosis of EPC, both of which were abolished by PI 3-kinase inhibitor, LY294002. High glucose significantly suppressed the basal and VEGF-stimulated phosphorylation of Akt in EPC. Furthermore, the number of circulating EPC was decreased in type 2 diabetic patients, although there were no significant differences in the serum levels of VEGF between control subjects and diabetic patients. CONCLUSIONS These findings suggest that high glucose impairs the functions of EPC through the suppression of Akt phosphorylation stimulated by VEGF.

Abstract
Tumors of the parapharyngeal space are said to account for 0.5% of all head and neck tumors, and are thus relatively rare. We performed histopathological examination of 76 tumors of the parapharyngeal space in patients hospitalized at the International University of Health and Welfare, Mita Hospital Head and Neck Oncology and Surgery center for 6 years from July 2005 to June 2011. There were 35 men and 41 women; the patients ranged in age from 15 to 78 years with a median age of 44. We performed preoperative CT and MRI, aspiration biopsy cytology (fine needle aspiration [FNA]) and postoperative histopathology diagnosis. There were 69 benign tumors (90.8%), and 7 malignant tumors (11.8%). Among the benign tumors were 32 schwannomas (42.1%) and 28 pleomorphic adenomas (36.8%). A total of 26 tumors of prestyloid origin were pleomorphic adenomas (93.8%), and 28 tumors of poststyloid origin were schwannomas (87.5%); all 7 malignant tumors (100%) were of prestyloid origin. There were 55 patients who underwent preoperative FNA, and the proper diagnosis rate was 70.9% (39/55 case). Preoperative imaging seemed to be very useful for predicting the histopathology. Furthermore, it would be desirable for FNA to be performed preoperatively for tumors of prestyloid origin, in consideration of the likelihood of such tumors being malignant. We think that there is room for improvement in the accurate FNA diagnosis rate.

Abstract
OBJECTIVE Supracricoid laryngectomy with Cricohyoidoepiglottopexy (SCL-CHEP) is a functional organ preservation surgery for laryngeal cancers. Post-operative laryngeal function is generally promising. Some patients, however, cannot attain satisfactory functional results because of an excessively wide neoglottis resulting in an insufficient neoglottal closure. Autologous buccal fat augmentation was conducted to correct the insufficiency. PATIENTS AND METHODS Two patients underwent intervention. Under general anesthesia, autologous fat was harvested from the buccal fat pad. Fat tissue was injected into the widest plane of the neoglottis under direct laryngoscopy; a navigation system was incorporated to identify the responsible site. Acoustic, aerodynamic, and perceptual analyses along with videofluoroscopic swallowing study and screening questionnaires were used for functional evaluation. RESULTS A total of 0.8ml (Case 1) and 0.7ml (Case 2) of fat tissues were injected into the submucosal space of the responsible sites. Both patients experienced functional improvement subjectively after augmentation; psychological parameters for voice and swallowing also improved. CONCLUSIONS Buccal fat augmentation to correct insufficient neoglottal closure after SCL-CHEP was technically feasible. A navigation system was helpful for confirmation. Fat absorption occurred and one third of the volume remained at 3 and 6 months. Although, vocal measurements remained unchanged, psychological parameters for voice and swallowing improved.

Abstract
The faecal microbiota of 166 healthy Japanese newborns was analysed periodically from day 1 after birth until the age of 3 years by using the reverse transcription-quantitative PCR. Faecal pH and the organic acid concentration were also examined. Colonisation by both facultative anaerobes and strict anaerobes was confirmed in 95% of the meconium tested. Bifidobacterium-predominant microbiota was established subsequently in most of the infants by 3 months after birth. Bifidobacterium breve, Bifidobacterium longum, Bifidobacterium infantis, Bifidobacterium catenulatum group and Bifidobacterium bifidum were the species mainly detected. Intergroup correlation analysis revealed that the bifidobacterial population levels, but not other strict anaerobe groups, were found to be negatively correlated with those of the Enterobacteriaceae from 7 days until 3 months after birth. Faecal pH was maintained at about 6 until 6 months after birth and reached 6.6 at 3 years after birth. The initial concentration of faecal organic acids (19 μM/g of faeces) just after birth increased until 3 years after birth to the level of 111 μM/g of faeces. Early start of feeding formula milk promoted colonisation by obligate anaerobes such as the Clostridium coccoides group, the Clostridium leptum subgroup, Prevotella, and Atopobium cluster during the 3 months after birth. Population levels of the bifidobacteria until 1 month after birth and those of the Bacteroides fragilis group until 6 months after birth were lower in infants delivered by Caesarean section than in those delivered normally. The results suggested that both earlier start of feeding of formula milk and the mode of infant delivery were found to be important in the development of intestinal microbiota in early infancy.

Abstract
Objective: A history of radiation therapy is known to be a major risk factor promoting postsurgical complications. By comparing the clinical outcomes of supracricoid partial laryngectomy with cricohyoidoepiglottopexy (SCPL-CHEP) in radiated and nonradiated patients, we investigated the usefulness of salvage SCPL-CHEP. Method: Among 61 patients who received SCPL-CHEP between 1997 and 2010, 25 (41%) had received radiation therapy preoperatively and 36 (59%) had not. Staging error, wound infection, accuracy of surgical margin determination, acquired laryngeal function, and prognosis were compared between the two groups. Results: Staging error occurred in 5 out of 25 (20%) irradiated and 13 out of 36 (36%) nonirradiated patients. Wound infection developed in 11 out of 25 (44%) irradiated and 5 out of 36 (14%) nonirradiated patients. Delayed wound infection (eg, infection appearing more than 1 month after an uneventful postsurgical course) was identified in 4 patients with a radiation dose over 65 Gy. Intraoperative margin study demonstrated dysplastic or positive margin in 13 out of 25 (52%) irradiated and 9 out of 36 (25%) nonirradiated patients. Swallowing function (ability to eat out) was acquired in 23 out of 25 (92%) irradiated and 32 out of 36 (89%) nonirradiated patients. Five-year overall survival rates were 83% in both groups. Conclusion: Risk of infection was significantly higher in irradiated patients; delayed infection should be appropriately managed. Functional and oncological results were stable regardless of radiation history. When salvage SCPL-CHEP is the only option to save a functioning larynx, head and neck surgeons are encouraged to take reasonable risks in performing SCPL-CHEP.

Abstract
The age structure of breeding females of Hynobius nebulosus has not been studied sufficiently. We estimated the ages of 76 individuals from a population in Kyoto by using skeletochronology. The mean age and snout-vent length (SVL) of this population were 4.6 years and 55.7 mm, respectively. It was estimated that the youngest females breed two years post hatching at a mean SVL of 46.5 mm, but a larger number of individuals begins breeding at three years and a mean SVL of 52.2 mm. Because most males also start to breed at three years, there seems to be no gender difference in the timing of sexual maturation. The age of the oldest female was estimated to be 11.8 years. It is possible that the life history of H. nebulosus is characterized by early maturation and arrested growth, and short longevity.

Abstract
Treatment of olefins bearing a directing group with alpha,beta-unsaturated carbonyl compounds, alkynes, or aldehydes in the presence of a catalytic amount of a rhenium complex, [ReBr(CO)(3)(thf)](2) gave gamma,delta-unsaturated carbonyl compounds, dienes, and allyl silyl ethers, respectively. This reaction proceeds via C-H bond activation, insertion of unsaturated molecules into the formed rhenium-carbon bond, and then reductive elimination (or transmetalation in the case of aldehydes).

Abstract
Adiponectin has anti-atherosclerotic effects through its direct actions on vascular cells. The present study investigates the molecular mechanisms of adiponectin in the migration of endothelial progenitor cells (EPCs) which play an important role in neovascularization and re-endothelization. The phosphorylation of Akt and the activations of Cdc42 and Rac1 were significantly increased by adiponectin. Adiponectin increased the migration activity of EPCs, which was completely inhibited by a PI3-kinase inhibitor. siRNA of Cdc42 or Rac1 completely inhibited the adiponectin-induced migration, but siRNA of Akt had no effects, indicating that adiponectin promotes the migration activities of EPCs mainly through PI3-kinase/Cdc42/Rac1.

Abstract
OBJECTIVE Mesenchymal stem cells (MSCs) have been reported to secrete various cytokines that exhibit angiogenic and neurosupportive effects. This study was conducted to investigate the effects of MSC transplantation on diabetic polyneuropathy (DPN) in rats. RESEARCH DESIGN AND METHODS MSCs were isolated from bone marrow of adult rats and transplanted into hind limb skeletal muscles of rats with an 8-week duration of streptozotocin (STZ)-induced diabetes or age-matched normal rats by unilateral intramuscular injection. Four weeks after transplantation, vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) productions in transplanted sites, current perception threshold, nerve conduction velocity (NCV), sciatic nerve blood flow (SNBF), capillary number-to-muscle fiber ratio in soleus muscles, and sural nerve morphometry were evaluated. RESULTS VEGF and bFGF mRNA expression were significantly increased in MSC-injected thigh muscles of STZ-induced diabetic rats. Furthermore, colocalization of MSCs with VEGF and bFGF in the transplanted sites was confirmed. STZ-induced diabetic rats showed hypoalgesia, delayed NCV, decreased SNBF, and decreased capillary number-to-muscle fiber ratio in soleus muscles, which were all ameliorated by MSC transplantation. Sural nerve morphometry showed decreased axonal circularity in STZ-induced diabetic rats, which was normalized by MSC transplantation. CONCLUSIONS These results suggest that MSC transplantation could have therapeutic effects on DPN through paracrine actions of growth factors secreted by MSCs.

Abstract
Treatment of an alpha,beta-unsaturated ketimine with an alpha,beta-unsaturated carbonyl compound in the presence of a rhenium complex, Re2(CO)10, gave a cyclopentadienyl-rhenium complex. This reaction proceeds via rhenium-catalyzed C-H bond activation of an olefinic C-H bond, insertion of an alpha,beta-unsaturated carbonyl compound into a Re-C bond of the alkenylrhenium intermediate, intramolecular nucleophilic cyclization, reductive elimination, elimination of aniline to give a cyclopentadiene derivative, followed by the formation of a cyclopentadienyl-rhenium complex from the cyclopentadiene derivative and the rhenium complex.

Abstract
The aim of this study was to elucidate the influence of change in sound tone of playing wind instruments on activity of jaw-closing muscles and the effect of sustained playing for a long time on fatigue of jaw-closing muscles. Electromyograms (EMG) of 19 brass instrument players and 14 woodwind instrument players were measured while playing instruments in tuning tone and high tone and under other conditions. Nine brass instrument players and nine woodwind instrument players played instruments for 90 min. Before and after the exercise, power spectral analyses of EMG from masseter muscles at 50% of maximum voluntary clenching level were performed and mean power frequency (MPF) were calculated. Root mean square (RMS) of EMG in masseter and temporal muscles while playing were slightly larger than those at rest but extremely small in comparison with those during maximum clenching. Root mean square in orbicularis oris and digastric muscles were relatively large when playing instruments. In the brass instrument group, RMS in high tone was significantly higher than that in tuning tone in all muscles examined. In the woodwind instrument group, RMS in high tone was not significantly higher than that in tuning tone in those muscles. Mean power frequency was not decreased after sustained playing in both instrument groups. These findings indicate that contractive load to jaw-closing muscles when playing a wind instrument in both medium and high tone is very small and playing an instrument for a long time does not obviously induce fatigue of jaw-closing muscles.
