Abstract
Primary cilia (PC) are non-motile, antenna-like structures on the cell surface. Many types of neoplasms exhibit PC loss, whereas in some neoplasms PC are retained and involved in tumourigenesis. To elucidate the PC status and characteristics of major salivary gland tumours (SGTs), we examined 100 major SGTs encompassing eight histopathological types by immunohistochemical analysis. PC were present in all (100%) of the pleomorphic adenomas (PAs), basal cell adenomas (BCAs), adenoid cystic carcinomas (AdCCs), and basal cell adenocarcinomas (BCAcs) examined, but absent in all (0%) of the Warthin tumours, salivary duct carcinomas, mucoepidermoid carcinomas, and acinic cell carcinomas examined. PC were also detected by electron-microscopic analysis using the NanoSuit method. It is worthy of note that the former category and latter category of tumours contained and did not contain a basaloid/myoepithelial differentiation component, respectively. The four types of PC-positive SGTs showed longer PC than normal and exhibited a characteristic distribution pattern of the PC in the ductal and basaloid/neoplastic myoepithelial components. Two PC-positive carcinomas (AdCC and BCAc) still possessed PC in their recurrent/metastatic sites. Interestingly, activation of the Hedgehog signalling pathway, shown by predominantly nuclear GLI1 expression, was significantly more frequently observed in PC-positive SGTs. Finally, we identified tau tubulin kinase 2 (TTBK2) as being possibly involved in the production of PC in SGTs. Taken together, our findings indicate that SGTs that exhibit basaloid/myoepithelial differentiation (PA, BCA, AdCC, and BCAc) are ciliated, and their PC exhibit tumour-specific characteristics, are involved in activation of the Hedgehog pathway, and are associated with TTBK2 upregulation, providing a significant and important link between SGT tumourigenesis and PC. © 2021 The Pathological Society of Great Britain and Ireland.

Abstract
BACKGROUND We sought to identify the risk factors of totally implantable central venous access port (TICVAP)-related infections in patients with malignant disease. PATIENTS AND METHODS Overall, 324 consecutive patients who received a TICVAP at our institution were retrospectively analysed. We further analysed cases of TICVAP-related complications. The risk factors for TICVAP-related infection were investigated using Cox regression hazard models. RESULTS With a median TICVAP duration of 268 days (range=1-1,859 days), TICVAP-related complications were observed in 36 cases and infectious complications in late phase were the most common, seen in 19 cases (9.26%). A multivariate analysis showed that patients with head and neck malignancy (p<0.001) and patients who received TICVAP insertion in the upper arm (p<0.001) were independently at a higher risk for TICVAP-related infections. CONCLUSION Patients with head and neck malignancy or TICVAP insertion in the upper arm have potentially increased risk for late-phase TICVAP-related infections.

Abstract
A growing body of evidence indicates that telomere dysfunction is a biological marker of progression in several types of cancer. However, the association between head and neck squamous cell carcinoma (HNSCC) and telomere length (TL) remains unknown. We measured the absolute TL levels in a well-characterised dataset of 211 tumoral vs normal tissues obtained from the same patients by quantitative polymerase chain reaction assay. Normalised TL levels were significantly lower in tumour samples than in normal tissue (P < 0.001) and there was a positive correlation between tumour tissue and normal mucosal tissue (R2 = 0.176, P < 0.001). We were able to distinguish two classes, one with a tumour/normal TL ratio ≤ 0.3 (38.4%), which showed clear telomere erosion, and the other with a tumour/normal TL ratio > 0.3 (61.6%), in which the TL was slightly shorter or longer than that in normal tissue. Notably, the tumour/normal TL ratio was correlated with the likelihood of disease recurrence (P = 0.002), the 5-hydroxymethylcytosine level (P = 0.043), and expression of the ten-eleven translocation (TET) gene (P = 0.043). Our findings show that TL shortening and subsequent low levels of 5-hydroxymethylcytosine and TET expression may contribute to development of HNSCC.

Abstract
Background New biomarkers are urgently needed to improve personalized treatment approaches for head and neck squamous cell carcinoma (HNSCC). Global DNA hypomethylation has wide-ranging functions in multistep carcinogenesis, and the hypomethylation of long interspersed nucleotide element-1 (LINE-1) is related to increased retrotransposon activity and induced genome instability. However, little information is available regarding LINE-1 hypomethylation and its prognostic implications in HNSCC. Methods In this study, we analyzed LINE-1 hypomethylation levels in a well-characterized dataset of 317 primary HNSCC tissues and 225 matched pairs of normal mucosa tissues, along with five oral cavity cancer (OCC) circulating tumor DNA (ctDNA) samples using quantitative real-time methylation and unmethylation PCR. The analysis was performed according to various clinical characteristics and prognostic implications. Results The results demonstrated that LINE-1 hypomethylation levels were significantly higher in the HNSCC tissues than in corresponding normal tissues from the same individuals (P < 0.001). Univariate analysis revealed that high levels of LINE-1 hypomethylation were correlated with poor disease-free survival (DFS; log-rank test, P = 0.038), whereas multivariate analysis demonstrated that they were significant independent prognostic factor for DFS (hazard ratio: 2.10, 95% confidence interval: 1.02–4.36; P = 0.045). Moreover, samples with high LINE-1 hypomethylation levels exhibited the greatest decrease in 5-hydroxymethylcytosine (5-hmC) levels and increase in tumor-suppressor gene methylation index (P = 0.006 and P < 0.001, respectively). Further, ctDNA studies also showed that LINE-1 hypomethylation had high predictive ability in OCC. Conclusions LINE-1 hypomethylation is associated with a higher risk of early OCC relapse, and is hence, a potential predictive biomarker for OCC. Furthermore, 5-hmC levels also exhibited predictive potential in OCC, based on their inverse correlation with LINE-1 hypomethylation levels. LINE-1 hypomethylation analysis, therefore, has applications in determining patient prognosis and real-time surveillance of disease recurrence, and could serve as an alternative method for OCC screening.

Abstract
Differences in the biology of human papillomavirus (HPV)-associated oropharyngeal cancers (OPCs) and HPV-negative OPCs may have implications in patient management. Early detection is imperative to reduce HPV-associated OPC mortality. Circulating tumor DNA (ctDNA) can potentially serve as a biomarker for monitoring clinically relevant cancer-related genetic and epigenetic modifications. We analyzed the methylation status of 24 G protein-coupled receptor (GPCR) genes in verification (85 OPC primary samples) and validation (8 OPC ctDNA samples) studies using quantitative methylation-specific polymerase chain reaction (Q-MSP). The Q-MSP-based verification study with 85 OPC primary samples revealed the GPCR genes that were significantly associated with recurrence in high methylation groups (≥14 methylated genes) with OPC and HPV-associated OPC (p < 0.001). In the Kaplan–Meier estimate and multivariate Cox proportional hazard analyses, 13 GPCR genes were significantly related to increased recurrence in the methylation group. Furthermore, the validation study on ctDNA showed that three of these genes (Prostaglandin D2 receptor 1: PTGDR1, Prostaglandin D2 receptor 2: PTGDR2, and Prostaglandin I2 Receptor: PTGIR) had a prediction performance as emerging biomarkers. We characterized the relationship between the methylation status of GPCR genes and outcomes in HPV-associated OPC. Our results highlight the potential utility of ctDNA methylation-based detection for the clinical management of HPV-associated OPC.

Abstract
Human papilloma virus (HPV)-associated oropharyngeal cancer (OPC) is an independent tumour type with regard to cellular, biological, and clinical features. The use of non-invasive biomarkers such as circulating tumour DNA (ctDNA) may be relevant in early diagnosis and eventually improve the outcomes of patients with head and neck squamous cell carcinoma (HNSCC). Genome-wide discovery using RNA sequencing and reduced representation bisulfite sequencing yielded 21 candidates for methylation-targeted genes. A verification study (252 HNSCC patients) using quantitative methylation-specific PCR (Q-MSP) identified 10 genes (ATP2A1, CALML5, DNAJC5G, GNMT, GPT, LY6D, LYNX1, MAL, MGC16275, and MRGPRF) that showed a significant increase recurrence in methylation groups with OPC. Further study on ctDNA using Q-MSP in HPV-associated OPC showed that three genes (CALML5, DNAJC5G, and LY6D) had a high predictive ability as emerging biomarkers for a validation set, each capable of discriminating between the plasma of the patients from healthy individuals. Among the 42 ctDNA samples, methylated CALML5, DNAJC5G, and LY6D were observed in 31 (73.8%), 19 (45.2%), and 19 (45.2%) samples, respectively. Among pre-treatment ctDNA samples, methylated CALML5, DNAJC5G, and LY6D were observed in 8/8 (100%), 7/8 (87.5%), and 7/8 (87.5%) samples, respectively. Methylated CALML5, DNAJC5G, and LY6D were found in 2/8 (25.0%), 0/8 (0%), and 1/8 (12.5%) of the final samples in the series, respectively. Here, we present the relationship between the methylation status of three specific genes and cancer recurrence for risk classification of HPV-associated OPC cases. In conclusion, ctDNA analysis has the potential to aid in determining patient prognosis and real-time surveillance for disease recurrences and serves as an alternative method of screening for HPV-associated OPC.

Abstract
Background Chronic inflammation is a risk factor for head and neck squamous cell carcinoma (HNSCC) and other diseases. Prostanoid receptors are clearly involved in the development of many types of cancer. However, their role is not simple and is poorly understood in HNSCC. Methods Methylation profiles of prostanoid receptor family genes were generated for tumour samples obtained from 274 patients with HNSCC, including 69 hypopharynx, 51 larynx, 79 oral cavity, and 75 oropharynx tumour samples, by quantitative methylation-specific PCR. Promoter methylation was then evaluated with respect to various clinical characteristics and patient survival. Results The mean number of methylated genes per sample was 2.05 ± 2.59 (range 0 to 9). Promoters of PTGDR1, PTGDR2, PTGER1, PTGER2, PTGER3, PTGER4, PTGFR, PTGIR, and TBXA2R were methylated in 43.8%, 18.2%, 25.5%, 17.5%, 41.2%, 8.0%, 19.3%, 20.4%, and 11.3% of the samples, respectively. Methylation indices for prostanoid receptor family genes tended to be higher as the number of TET methylation events increased. Patients with 5–9 methylated genes had a significantly lower survival rate than that of patients with 0–4 methylated genes (log-rank test, P= 0.007). In multivariate analyses, PTGDR1 methylation was most highly correlated with recurrence in patients with hypopharyngeal cancer (P = 0.014). A similar correlation was observed for PTGER4 in patients with laryngeal cancer (P = 0.046). Methylation of the PTGIR and TBXA2R promoters was positively correlated with recurrence in oropharyngeal cancer (P = 0.028 and P = 0.006, respectively). Moreover, Patients with 5–9 methylated genes were extremely lower of 5hmC levels (P = 0.035) and was correlated with increasing expression of DNMT3A and DNMT3B (P < 0.05 and P < 0.05, respectively). Conclusion We characterised the relationship between the methylation status of prostanoid receptor genes and recurrence in HNSCC. These results provide new perspectives for the development of molecular targeted treatment approaches.

Abstract
BACKGROUND Infants admitted to the neonatal intensive care unit (NICU) have a higher incidence of congenital hearing loss compared with the healthy newborn population. OBJECTIVES To clarify the relationship between risk factors for hearing impairment in NICU-treated infants and deterioration of the auditory brainstem response (ABR) threshold during childhood. METHOD We screened 1,071 high-risk infants admitted to the NICU for hearing impairment. One-hundred forty-eight infants exhibited an abnormal ABR threshold of ≥40 dB nHL. We analyzed the correlation of change in ABR threshold with risk factors for future hearing impairment. RESULTS Among infants treated in the NICU, 148 (13.8%) exhibited an ABR threshold of ≥40 dB nHL; 107 of these 148 (72.3%) showed hearing change in the process (102 showed improvement to normal hearing level, whereas 5 showed further deterioration). Our analysis showed that the factors contributing to the elevation of ABR threshold were oxygen administration and chromosomal aberrations. CONCLUSIONS Factors related to the elevation of ABR threshold were oxygen administration and the presence of chromosomal aberrations. Awareness of risk factors that are more likely to cause hearing loss in infants may aid in follow-up treatment of these children.

Abstract
An ameloblastoma is a locally aggressive odontogenic tumour that commonly develops from the odontogenic epithelium within the jawbone. Here we present for the first time a case of a rare primary ameloblastoma in the middle ear cavity, along with some consideration of its treatment and a new classification. A 65-year-old woman presented with a left middle ear cavity tumour. Pathological examination led to the diagnosis of an ameloblastoma. We resected the tumour along with an extensive part of the middle ear mucosa, which made it difficult to have an adequate margin. It is recommended that the remaining bone be ground 2-3 mm beyond the visible margin after resecting the gross tumour. Therefore, several cases are treated with conservative surgery, including physicochemical treatment. This factor should be considered when designing treatment strategies as good alternatives in cases where resection with an adequate margin is difficult.

Abstract
Loss of heterozygosity (LOH) on chromosome 18q23 is associated with significantly decreased survival in head and neck cancer. In agreement with such tumor suppressive roles, the loss of function of genes located in this region can be achieved through LOH and promotor hypermethylation. In this study, the methylation status of promoters of 18q23 genes in 243 head and neck cancer patients was assessed by quantitative methylation-specific PCR. Promoter methylation was then compared to various clinical characteristics and patient survival. GALR1 and SALL3 promoter methylation correlated with reduced disease-free survival (log-rank test, p = 0.018 and p = 0.013, respectively). Furthermore, based on multivariate Cox proportional hazards analysis, these methylation events were associated with poor disease-free survival, with hazard ratios of 1.600 (95% confidence interval: CI, 1.027–2.493; p = 0.038) and 1.911 (95% CI, 1.155–3.162; p = 0.012), respectively. By comparison, GALR1 and SALL3 methylation were not prognostic for overall survival in The Cancer Genome Atlas (TCGA) cohort. Our findings suggest that the methylation status of 18q23 genes could serve as important biomarkers for the prediction of clinical outcomes in well-annotated head and neck squamous cell carcinoma cohorts. GALR1 and SALL3 methylation could thus help to facilitate risk stratification for individualized treatment.

Abstract
We analyzed 356 patients with idiopathic sudden sensorineural hearing loss treated with hyperbaric oxygen therapy and systemic steroids (n = 161), systemic steroids alone (n = 160), or intratympanic and systemic steroids (n = 35). The main outcome measure was the hearing recovery rate. The effect of other variables, including the initial averaged 5-frequency hearing level, patient age, interval between the onset of symptoms and treatment, presence of vertigo as a complication, presence of diabetes mellitus, smoking history, and presence of hypertension, on the hearing recovery rate was also evaluated. The overall hearing recovery rate was significantly higher for the patients treated with hyperbaric oxygen therapy and systemic steroids than for those treated with systemic steroids alone (p < 0.001) or systemic and intratympanic steroids (p < 0.001). The presence of vertigo negatively affected hearing recovery. Our findings suggest that hyperbaric oxygen therapy confers a significant additional therapeutic benefit when used in combination with steroid therapy for idiopathic sudden sensorineural hearing loss.

Abstract
Huge cervical and mediastinal masses may lead to acute respiratory failure caused by laryngotracheal compression and airway obstruction. Thyroid storm is also a life-threatening endocrine emergency originating almost exclusively from uncontrolled Graves' disease. We report a case of a 42-year-old man with acute upper airway obstruction and tachycardia from progressive swelling of a giant thyroid, in conjunction with thyroid storm resulting from uncontrolled Graves' disease. Fibreoptic-assisted nasal intubation was performed while the patient was awake, immediately followed by emergency total thyroidectomy via a cervical and sternal approach. The patient had an uneventful postoperative course and recovered well. Respiratory failure due to swelling of a giant thyroid is a life-threatening condition and should be treated immediately with endotracheal intubation while the patient is awake following emergent total thyroidectomy, even with a sternotomy.

Abstract
Acoustic neuroma sometimes presents with sudden-onset sensorineural hearing loss as a primary symptom. We investigated 848 untreated cases that included 20 cases with acoustic neuroma with sudden-onset sensorineural hearing loss and 828 cases without acoustic neuroma. Fourteen of the 20 acoustic neuroma and 90 of the 828 cases of sudden-onset sensorineural hearing loss showed a trough-shaped audiogram with the greatest amount of hearing loss in the mid-frequency range. The incidence of a trough-shaped audiogram was significantly higher in patients with acoustic neuroma than in those without (p < 0.01). This study suggests that a trough audiogram is a significant finding in patients with sudden-onset sensorineural hearing loss and indicates the presence of acoustic neuroma.

Abstract
Abstract
Staging and pathological grading are useful, but imperfect predictors of recurrence in head and neck squamous cell carcinoma (HNSCC). Accordingly, molecular biomarkers that predict the risk of recurrence are necessary to improve clinical outcomes. The ability to distinguish between low- and high-risk HNSCCs at an early stage may reduce follow-up costs. We hypothesized that the quantitative methylation specific PCR (Q-MSP) assay could be used to define patterns of DNA methylation that differentiate low- and high-risk HNSCCs. The methylation statuses of the promoters of 11 tumor-related genes (p16, RASSF1A, E-cadherin, H-cadherin, MGMT, DAPK, DCC, COL1A2, TAC1, SST, and GALR1) were analyzed in 133 HNSCC cases using quantitative methylation-specific PCR. Frequent methylation of p16 (44%), RASSF1A (18%), E-cadherin (53%), H-cadherin (35%), MGMT (35%), DAPK (53%), DCC (42%), COL1A2 (44%), TAC1 (61%), SST (64%), and GALR1 (44%) in HNSCC were detected. Disease-free survival was lower in patients with 6-11 methylated genes than in those with 0-5 methylated genes (log-rank test, P = 0.001). In a multivariate Cox proportional hazards analysis, the methylation of E-cadherin, COL1A2, TAC1, and GALR1 was associated with poor survival, with hazard ratios of 4.474 (95% CI, 1.241-16.124). In a joint analysis of these four genes, patients with 2-4 methylated genes had a significantly lower survival rate than those with 0-1 methylated genes in early-stage HNSCC. Importantly, the methylation of some genes was closely related to poor prognosis in early-stage HNSCC, providing strong evidence that these hypermethylated genes are valuable biomarkers for prognostic evaluation. In conclusion, the methylation profiles of E-cadherin, COL1A2, TAC1, and GALR1 were the most powerful combination for predicting early-stage HNSCC. This demonstrates that molecular stratification may predict cancer progression. These findings can benefit HNSCC screening and surveillance algorithms. Although our study was retrospective, was conducted at a single institution, and the number of patients was small, it serves as a platform to establish optimal therapeutic strategies for early-stage HNSCC.

Abstract
Abstract
Staging and pathological grading systems are useful but imperfect predictors of recurrence in head and neck squamous cell carcinoma (HNSCC). The aim of this study was to determine the methylation status of eight GPCR-encoding genes in HNSCCs and its relationship to recurrence, survival, and clinical characteristics (e.g., tumor location and lymph node metastasis). All eight genes (NPFFR1, NPFFR2, HCRTR1, HCRTR2, NPY1R, NPY2R, NPY4R, and NPY5R) encode neuropeptide receptors and are in the Class A β subgroup. This study is the first to implicate neuropeptide receptors in the genesis of HNSCC. To identify potential prognostic markers, we examined the methylation status of eight neuropeptide receptor gene promoters in 231 head and neck squamous cell carcinomas. The NPFFR1, NPFFR2, HCRTR1, HCRTR2, NPY1R, NPY2R, NPY4R, and NPY5R promoters were methylated in 80.5%, 79.2%, 67.1%, 73.2%, 35.1%, 36.4%, 38.5%, and 35.9% of the samples, respectively. In a multivariate Cox proportional hazards analysis, the odds ratio for recurrence was 2.044 (95% confidence interval [CI], 1.323-3.156; P = 0.001) when the NPY2R promoter was methylated. In patients without lymph node metastasis (n = 100), methylation of NPY2R (compared with methylation of the other seven genes) best correlated with poor disease-free survival (DFS) (odds ratio, 2.492; 95% CI, 1.190-5.215; P = 0.015). In patients with oral cancer (n = 69), methylated NPY1R and NPY2R were independent prognostic factors for poor DFS, both individually and, even more so, in combination (odds ratio, 3.90; 95% CI, 1.523-9.991; P = 0.005). Similar findings were observed for NPY2R and NPY4R in patients with oropharyngeal cancer (n = 162) (odds ratio, 5.663; 95% CI, 1.507- 21.28; P = 0.010). The present study suggests that the methylation status of the NPY1R, NPY2R, and NPY4R genes is an independent indicator of DFS in patients with oral and/or oropharyngeal cancers. Our findings support the use of methylation markers in patient selection for adjuvant therapy after initial surgical treatment and may aid oropharyngeal cancer screening and surveillance programs. However, they are preliminary and hence need to be validated in larger and more homogeneous HNSCC patient cohorts.

Abstract
The aim of this study was to clarify the epigenetic regulation of ten eleven translocation protein (TET) family genes, which can provide insights into the mechanisms of tumorigenesis and the risk of disease recurrence in head and neck squamous cell carcinoma (HNSCC). We generated methylation profiles of TET1, TET2 and TET3 genes in tumor samples obtained from 233 patients with HNSCC; these included 57 hypopharynx, 44 larynx, 69 oral cavity, and 63 oropharynx tumor samples. The mRNA expression and promoter DNA methylation of TET family genes were examined via quantitative RT-PCR and methylation-specific PCR, respectively. Promoter methylation was compared with various clinical characteristics and the TET methylation index (TE-MI). The TE-MI, representing the number of methylation events in TET family genes, was positively correlated with alcohol consumption (P = 0.004), high-risk human papilloma virus (HPV) status (P = 0.004) and disease recurrence (P = 0.002). The simultaneous methylation analysis of TET family genes was correlated with reduced disease-free survival in unfavorable event groups (log-rank test, P = 0.026). In the multivariate Cox proportional hazards analysis, TET3 methylation in T1 and T2 tumor stages, oropharyngeal cancer, and oral cancer patients exhibited high association with poor survival (hazard ratio: 2.64, P = 0.014; 3.55, P = 0.048; 2.63, P = 0.028, respectively). A joint analysis of the tumor suppressor gene methylation index showed a significant trend toward a higher TE-MI. The methylation status of TET3 was independently associated with aggressive tumor behavior and a global effect on DNA methylation status in HNSCC.

Abstract
Salivary duct carcinoma (SDC) constitutes one of the most aggressive cancers in the salivary gland and is associated with a poor prognosis; however, no established systemic therapy options are available. SDC exhibits biological similarity to prostate and breast cancers, therefore anti-hormone therapy and molecular target therapies are available, however with limited beneficial effects. Galanin and galanin receptors (GALRs) are well established as molecular biomarkers to predict the survival rate and risk of recurrence of head and neck squamous cell carcinoma. The present study investigated the clinicopathological features of patients with SDC and the methylation status of their galanin and GALR genes to demonstrate the prognostic value for this disease. The median overall survival (OS) was 37.2 months. T-stage, N-stage, disease stage, tumor size, and preoperative facial paralysis were significantly associated with OS, whereas human epidermal growth factor receptor 2 (HER2) overexpression was not. GALR1 and GALR2 methylation rates in tumor tissues were significantly increased compared with normal tissues with 9.85- and 4.49-fold increase, respectively. p27kip1 and p57kip2 expression significantly inversely correlated with the methylation rate of GALR1 and GALR2. In addition, the observed GALR1 and/or GALR2 methylation rates were significantly correlated with a decrease in OS. These results suggest that GALR1 and GALR2 may serve as potential prognostic factors and therapeutic targets in SDC.

Abstract
Background Staging and pathological grading systems are convenient but imperfect predictors of recurrence in head and neck squamous cell carcinoma (HNSCC). Identifying biomarkers for HNSCC that will progress and cause death is a critical research area, particularly if the biomarker can be linked to selection of patients. Therefore, to identify potential alternative prognostic markers, we investigated the methylation status of five neuropeptide gene promoters. The promoter methylation status was determined by quantitative methylation-specific PCR in 230 cases of HNSCC; 58 hypopharynx, 45 larynx, 56 oropharynx, and 71 oral cavity tumor samples were studied. Results The somatostatin (SST), tachykinin precursor 1 (TAC1), hypocretin neuropeptide precursor (HCRT), neuropeptide Y (NPY), and galanin (GAL) promoters were methylated in 84.3, 63.5, 32.6, 28.3, and 20.0%, respectively, of the samples. The mean number of methylated genes per sample was 2.29 (range, 0–5). Disease-free survival was lower in patients with 3–5 methylated genes than in those with 0–2 methylated genes (log-rank test, P = 0.007). In multivariate Cox proportional hazards analysis, TAC1 and GAL promoter methylation independently predicted recurrence (odds ratios 1.620, 95% confidence interval [CI] 1.018–2.578, P = 0.042, and odds ratios 1.692, 95% CI 1.063–2.694, P = 0.027, respectively). In patients with oral cancer, TAC1 methylation showed the best correlation with poor survival (odds ratio 4.427, 95% CI 1.634–12.00, P = 0.003). Similar findings were observed for HCRT and GAL in patients with laryngeal cancer and oropharyngeal cancer, respectively. Conclusion In this study, we demonstrated the methylation status of the neuropeptide-encoding genes SST, TAC1, HCRT, NPY, and GAL and its relationship with recurrence and survival in HNSCC. These methylation changes may serve as potential molecular markers for defining the risk and prognosis of HNSCC.

Abstract
Clarifying the epigenetic regulation of tumor-related genes (TRGs) can provide insights into the mechanisms of tumorigenesis and the risk for disease recurrence in HPV-negative head and neck cancers, originating in the hypopharynx, larynx, and oral cavity. We analyzed the methylation status of the promoters of 30 TRGs in 178 HPV-negative head and neck cancer patients using a quantitative methylation-specific PCR. Promoter methylation was correlated with various clinical characteristics and patient survival. The mean number of methylated TRGs was 14.2 (range, 2-25). In the multivariate Cox proportional hazards analysis, the methylation of COL1A2 and VEGFR1 was associated with poor survival for hypopharyngeal cancer, with hazard ratios: 3.19; p = 0.009 and 3.07; p = 0.014, respectively. The methylation of p16 and COL1A2 were independent prognostic factors for poor survival in laryngeal cancer (hazard ratio: 4.55; p = 0.013 and 3.12; p = 0.035, respectively). In patients with oral cancer, the methylation of TAC1 and SSTR1 best correlated with poor survival (hazard ratio: 4.29; p = 0.005 and 5.38; p = 0.029, respectively). Our findings suggest that methylation status of TRGs could serve as important site-specific biomarkers for prediction of clinical outcomes in patients with HPV-negative head and neck cancer.

Abstract
BACKGROUND Tracheotomy for pediatric patients is a surgical procedure with greater technical difficulty and higher rates of morbidity and mortality than that in adults. We report a new technique for pediatric tracheotomy that reduces the issue of granulation and recannulation after accidental decannulation. METHODS Clinical data were retrospectively reviewed for 32 pediatric patients aged 3weeks-32months who underwent Quattro Flap Tracheotomy (QFT) at our hospital. The technique for the procedure is described and illustrated in detail. We analyzed the complications of surgery and the prognosis of patients. RESULTS Twenty-seven out of 32 pediatric tracheotomy patients were aged <12months. Overall, one patient with subglottic stenosis developed granulation and required a resection. Three patients with granulation were cured using conservative treatment. Neither pneumothorax nor accidental decannulation and failure to reinsert the cannula occurred with QFT. No tracheotomy-related deaths occurred. The overall rate of postoperative complications was lower in the study group (4/32 cases, 12.5%) than in the control group (12/32 cases, 37.5%; p=0.041). CONCLUSION QFT is a new method for pediatric tracheotomy that should be performed in younger infants. If performed appropriately, QFT may reduce the incidence of complications and death in many cases that involve persistent granulation. LEVELS OF EVIDENCE IV.

Abstract
The aim of this study was to determine the methylation status of the genes encoding the vascular endothelial growth factor receptors and to evaluate the usefulness of VEGFR methylation as a prognostic indicator in head and neck squamous cell carcinoma. VEGFR messenger RNA expression and promoter methylation were examined in a panel of cell lines via quantitative reverse transcription and methylation-specific polymerase chain reaction, respectively. Promoter methylation was compared with clinical characteristics in 128 head and neck squamous cell carcinoma samples. The normalized methylation values for the VEGFR1, VEGFR2 and VEGFR3 promoters tended to be higher in the tumour cell lines than in normal tonsil samples, whereas amounts of VEGFR1, VEGFR2 and VEGFR3 messenger RNA were significantly higher. Methylation of the VEGFR1 promoter (p = 0.003; 66/128 head and neck squamous cell carcinoma samples, 52%) and VEGFR3 promoter (p = 0.043; 53/128 head and neck squamous cell carcinoma samples, 41%) significantly correlated with recurrence, whereas methylation of the VEGFR2 promoter significantly correlated with lymph node metastasis (p = 0.046; 47/128 head and neck squamous cell carcinoma samples, 37%). Concurrent methylation of the VEGFR1 and VEGFR3 promoters significantly correlated with reduced disease-free survival (log-rank test, p = 0.009). In a multivariate logistic regression analysis, methylation of the VEGFR1, VEGFR3 and both the VEGFR1 and VEGFR3 promoters independently predicted recurrence (odds ratios and 95% confidence intervals: 3.19, 1.51-6.75 (p = 0.002); 2.24, 1.06-4.76 (p = 0.035); and 2.56, 1.09-6.05 (p = 0.032), respectively). Methylation of the VEGFR promoters predicts poor prognosis in head and neck squamous cell carcinoma patients.

Abstract
PURPOSE EYS and USH2A are the most common causative genes for retinitis pigmentosa (RP) in Japan. We determined the clinical outcomes for USH2A-related non-syndromic RP or Usher syndrome type II (USH2). METHODS Two non-syndromic RP and 11 USH2 patients with previously identified USH2A mutations were included. Their complete history and medical records were collected using standard procedures. Visual fields and acuity were compared with those of patients with EYS mutations. Clinical analyses were based on ophthalmic and otolaryngologic examinations. RESULTS In all patients, the fundus displayed changes typical of RP. Most patients showed relatively well-preserved visual acuity in their thirties or forties, with rapid deterioration in their fifties. Concentric constriction started in the twenties or thirties, and no effective residual visual field was observed after the fifties. CONCLUSIONS The visual outcome for non-syndromic RP or USH2 patients with USH2A mutations is consistent with that for RP patients with EYS mutations.

Abstract
We evaluated the outcomes of and prognostic factors for idiopathic sudden sensorineural hearing loss (ISSNHL) treated with adjuvant hyperbaric oxygen therapy (HBOT). A retrospective review of clinical data was performed for 167 patients with ISSNHL who failed to respond to systemic steroids and were treated by adjuvant HBOT at Shizuoka Saiseikai General Hospital. We analysed the clinical outcomes, the averaged 5-frequency hearing level after systemic steroids, patient age, the interval between post-steroids and pre-HBOT, vertigo as a complication, the presence of diabetes mellitus, smoking history, and hypertension. Overall, after HBOT, complete recovery occurred in 16 (9.6%) of the patients, with definite improvement in 16 (9.6%) and slight improvement in 45 (26.9%). The overall rate of hearing improvement was higher in the study group (77/167 cases, 46.1%) than in the control group (52/160 cases, 32.5%; p = 0.021). If performed appropriately, HBOT should be able to improve hearing in many cases unresponsive to initial therapy.

Abstract
Introduction Small cell carcinoma/neuroendocrine carcinoma (SCNEC) of the oropharynx is uncommon. Two cases of SCNEC in an 81-year-old woman and in a 54-year-old man are presented here. Case description We have documented two cases of SCNEC arising in the oropharynx with evidence of high-risk human papillomavirus (HPV) infection. Histologically, both cases were classified as poorly differentiated SCNEC with high nuclear-to-cytoplasmic ratios and nuclear molding. Observations using a transmission electron microscope revealed membrane-bound neuroendocrine granules in some tumor cells. Both tumors expressed high levels of p16, a surrogate marker for high-risk HPV infection. HPV infection was confirmed in both cases using HPV polymerase chain reaction analysis; HPV subtype 16 was identified in one case and HPV subtype 18 in the other. Discussion and Evaluation SCNEC of the oropharynx is a rare and novel HPV-associated disease with neuroendocrine granules and aggressive clinical behavior. Conclusions Herein, we present two cases of SCNEC, focusing on its histologic features and treatment modalities. More studies are required to elucidate the pathophysiology of HPV-associated SCNEC in different organ systems.

Abstract
Conclusions This study suggests that long-term ventilation tube insertion is the first-choice surgical treatment for a 'sniff-type' patulous Eustachian tube (PET). When treating a refractory PET, it is important to determine whether the patient had a habitual sniff. Objectives PET patients were divided into two groups: patients with a habitual sniff (sniff-type PET) and those without a habitual sniff (non-sniff-type PET). This study examined the effects of ventilation tube insertion or silicone plug insertion in each group. Methods Surgical procedures such as ventilation tube insertion or trans-tympanic silicone plug insertion were performed for these patients. Tubotympanoaero-dynamic graphy (TTAG) was also performed to determine the mechanisms underlying these treatments. Results There were 11 cases (17 ears) of sniff-type PET and 20 cases (27 ears) of non-sniff-type PET. An improvement in symptoms was found in 72.7% of the patients who underwent silicone plug insertion (66.7% for sniff-type PET and 74.1% for non-sniff-type PET) and in 90.9% of the patients who underwent ventilation tube insertion for sniff-type PET. In TTAG assessments, many sniff-type PET patients showed significant synchronous changes at high levels of pressure (over 40 daPa) in the external auditory meatus and nasopharynx when performing a slight Valsalva manoeuvre (below 200 daPa).

Abstract
Background We report a rare case of a patient with a hypopharyngeal metastasis from breast cancer. Case presentation Isolated breast cancer metastasis to the hypopharynx has been previously reported in only one autopsy case. Herein, we report a 56-year-old woman with metastases to the hypopharynx almost 24 years after receiving a mastectomy and chemotherapy to treat primary breast carcinoma. We believe that she is the first patient to be treated for metastatic breast carcinoma to the hypopharynx. The hypopharyngeal tumor reduced in size after administration of an oral aromatase inhibitor. The patient has remained alive with a preserved larynx for three years. Conclusions Breast cancer metastasis to the hypopharynx is an extremely rare event.

Abstract
We herein report a very rare case of combined small-cell carcinoma (SmCC) of the hypopharynx, with a squamous cell carcinoma (SqCC) element. A 74-year-old man presented with a 3-month history of throat pain and hoarseness. On hypopharyngoscopy, a tumor was identified in the right anterior wall of the piriform sinus and, following examination of a biopsy sample, the lesion was diagnosed as SqCC. Total laryngectomy with bilateral neck dissection was performed and the malignancy was diagnosed as combined SmCC. One month after surgery, concomitant chemoradiotherapy with cisplatin and etoposide was administered. Immunohistochemically, the SmCC element was positive for CD56 and Ki-67 (50.2%), whereas the SqCC element was positive for cytokeratin 34βE12 and Ki-67 (47.5%). Furthermore, the SmCC element was positive for KIT and platelet-derived growth factor α (PDGFRα), while the SqCC element was positive for epidermal growth factor receptor (EGFR) and PDGFRα. By genetic analysis, a silent mutation in the PDGFRα gene was recognized. The expression of KIT, PDGFRα and EGFR in this case provided evidence that combined SmCC may be a candidate for molecular-targeted therapy, although further investigations are required.

Abstract
The aim of this study was to investigate the prognostic value of galanin (GAL) and galanin receptor (GALR) promoter hypermethylation in patients with head and neck squamous cell carcinoma (HNSCC). The methylation status of three genes-GAL, GALR1, and GALR2 was examined in HNSCC patient tumors using quantitative methylation-specific PCR (Q-MSP). To determine the prognostic value of GAL, GALR1 and GALR2 methylation status, their associations with various clinical characteristics and patient survival were assessed in HNSCC patient tumors (n = 142). Aberrant methylation of at least one gene was observed in 84 of the 142 (59.2 %) primary tumors analyzed. The methylation index, defined as the ratio between the number of methylated genes and the number of genes examined, was positively correlated with larger tumor size (P = 0.034) and disease recurrence (P < 0.001). In the multivariate logistic-regression analysis, methylation of both GAL and GALR1 exhibited the highest association with poor survival (hazard ratio, 6.83, P = 0.002). Moreover, among patients without lymph node metastasis, a multivariate analysis showed a significant trend for poor survival as the number of hypermethylated genes increased (log-rank test, P = 0.003). CpG hypermethylation is a likely mechanism of GAL and GALR1/2 gene inactivation, indicating that GAL and its receptors play a role in HNSCC tumorigenesis. As such, GAL and GALR1/2 methylation status may serve as an important biomarker for clinical outcome.

Abstract
A scanning acoustic microscope (SAM) calculates the speed of sound (SOS) through tissues and plots the data on the screen to form images. Hard tissues result in greater SOS; based on these differences in tissue properties regarding SOS, SAM can provide data on tissue elasticity. The present study evaluated whether tissue modifications, such as formalin fixation, periodic acid-Schiff (PAS) reactions and protein degradation, changed the acoustic properties of the tissues and whether SAM could be a useful tool for following chemical changes in sections. The fixation process was observable by the increased SOS. During the PAS reaction, the glycosylation of tissues was characterized by an increased SOS. Mucous or glycogen distribution was visualized and was found to be statistically comparable among lesions and states. Protease digestion by pepsin led to a decreased SOS. Tissue sensitivity to proteases varied due to the stage, cause and duration of inflammation or ageing. Changes in acoustic properties were more sensitive than those in optical histology. SAM facilitates the visualisation of the time course or distribution of chemical modifications in tissue sections, thus aiding their comparison among tissues. SAM may be an effective tool for studying changes such as protein cross-linkage, tissue repair and ageing.

Abstract
PURPOSE The aim of this study was to define somatostatin (SST) and somatostatin receptor type 1 (SSTR1) methylation profiles for head and neck squamous cell carcinoma (HNSCC) tumors at diagnosis and follow up and to evaluate their prognostic significance and value as a biomarker. METHODS Gene expression was measured by quantitative RT-PCR. Promoter methylation status was determined by quantitative methylation-specific PCR (Q-MSP) in HNSCC. RESULTS Methylation was associated with transcription inhibition. SST methylation in 81% of HNSCC tumor specimens significantly correlated with tumor size (P = 0.043), stage (P = 0.008), galanin receptor type 2 (GALR2) methylation (P = 0.041), and tachykinin-1 (TAC1) (P = 0.040). SSTR1 hypermethylation in 64% of cases was correlated with tumor size (P = 0.037), stage (P = 0.037), SST methylation (P < 0.001), and expression of galanin (P = 0.03), GALR2 (P = 0.014), TAC1 (P = 0.023), and tachykinin receptor type 1 (TACR1) (P = 0.003). SST and SSTR1 promoter hypermethylation showed highly discriminating receiver operator characteristic curve profiles, which clearly distinguished HNSCC from adjacent normal mucosal tissues. Concurrent hypermethylation of galanin and SSTR1 promoters correlated with reduced disease-free survival (log-rank test, P = 0.0001). Among patients with oral cavity and oropharynx cancer, methylation of both SST and SSTR1 promoters correlated with reduced disease-free survival (log-rank test, P = 0.028). In multivariate logistic-regression analysis, concomitant methylation of galanin and SSTR1 was associated with an odds ratio for recurrence of 12.53 (95% CI, 2.62 to 59.8; P = 0.002). CONCLUSIONS CpG hypermethylation is a likely mechanism of SST and SSTR1 gene inactivation, supporting the hypothesis that SST and SSTR1 play a role in the tumorigenesis of HNSCC and that this hypermethylation may serve as an important biomarker.

Abstract
BACKGROUND Reconstruction with free jejunal graft (FJG) is often performed for patients with hypopharyngeal or cervical esophageal cancer. During reconstruction with an FJG after pharyngoesophagectomy, it is critical to intraoperatively detect venous anastomotic failure and subsequent venous malperfusion to avoid postoperative FJG necrosis. This study introduces a novel method for assessing blood perfusion in FJGs by using indocyanine green (ICG) fluorescence angiography. METHODS We used ICG fluorescence angiography to quantitatively assess FJG blood perfusion in archived fluorescence video files from 26 patients who had undergone FJG transfer. A software program "ROIs", was used to create a time-fluorescence intensity curve. We retrospectively measured the maximum fluorescence intensity at the terminal ileum and the duration (T1/2max) between when the intensity began rising and when it reached half of the maximum. RESULTS Among the 26 patients, 5 patients suffered venous anastomotic failure. In three of these cases, anastomosis was corrected intraoperatively; the other two patients underwent a second FJG transfer. Retrospective assessment showed that the mean T1/2max at the FJG serosae was significantly longer in these five patients than that in FJGs with good blood perfusion. Our analysis revealed that a T1/2max >9.6 s may be a good indicator of FJG venous malperfusion. CONCLUSIONS Quantitative analysis of ICG fluorescence angiography proved useful for detecting venous anastomotic failure of FJG, and may help to reduce vascular problems in FJG reconstruction.

Abstract
Objectives: Evaluation of the clinical and pathological factors associated with treatment and outcomes for external auditory canal (EAC) carcinomas. Methods: Over the 20-year period from 1993 to 2013, a retrospective review of clinical and pathological analysis was performed on 23 patients who were histologically diagnosed with EAC carcinomas and treated at Hamamatsu University Hospital. We evaluated the clinical staging, treatment methods, pathological diagnosis (particularly squamous cell carcinoma [SCC])), and patient outcomes. Main outcome measures included staging, treatment procedures, pathological features, and estimated survival rates. Results: The 5-year overall survival (OS) of the subjects was 75.2%, and the 10-year OS was 60.2% with the Kaplan-Meier method. The prognosis for SCC was poor when compared with other carcinomas ( P = .0462). The prognosis following treatment with surgery alone and following postoperative radiotherapy or chemoradiotherapy was significantly better than for the group of patients with unresectable tumors ( P = .0004 and P = .0001). There was no significant difference between the 4 tumor stage groups. Information on patients’ survival status was obtained after a median follow-up period of 57.5 months (range, 7-151 months). Conclusions: Our survival analysis data for carcinoma of the EAC demonstrates that SCC and unresectable cases are associated with poor outcomes, and outcomes for subjects with operability more closely parallel the survival curves of advanced stage T4 disease. Patients with SCC should be strictly categorized as cases with severe disease.

Abstract
BACKGROUND The incidence rates of oropharyngeal squamous cell carcinoma (OPSCC) have risen steadily in the USA and in northern Europe. These increases are thought to be a consequence of persistent infection with high-risk human papillomavirus (HPV) in OPSCC patients. HPV is an emerging etiologic factor in OPSCC. In Japan, the incidence of OPSCC has significantly increased over the last three decades. However, the population of HPV-positive OPSCC patients is currently unknown. We examined the nationwide trends with regard to HPV incidence in OPSCC patients at 21 specific sites, and examined the relationship between the presence of HPV and survival in OPSCC patients in Japan. METHODS Tumor samples were obtained from patients with OPSCC prior to treatment, and HPV infection was investigated by polymerase chain reaction (PCR). Hybrid Capture 2 (HC2) was also adopted for swab examination on the surface of fresh tumors. RESULTS HPV was detected by PCR in 79 (50.3%) out of 157 OPSCC patients. The clinical features of HPV-positive OPSCC were low differentiation, a tendency to involve the lateral wall, and high nodal staging. The sensitivity and specificity of HC2 were 93.7 and 96.2%, respectively, indicating its utility as a screening test. HPV-positive patients had significantly better overall survival and disease-free survival than HPV-negative patients.
