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

Abstract
PURPOSE Occult metastasis is a prognostic factor for early-stage oral squamous cell carcinoma (OSCC). Sentinel lymph node (SLN) biopsy (SLNB) is a promising method to detect such metastases. The present study aimed to evaluate the diagnostic reliability of SLNB with computed tomography lymphography (CTL) for early-stage OSCC and to clarify patient outcomes after SLNB. METHODS The medical records of 42 patients with T1 or T2 cN0 OSCC who had undergone CTL the day before surgery were retrospectively collected and statistically analyzed. RESULTS SLNs were identified on CTL in 41 of 42 OSCC patients (97.6 %). Micrometastases were detected in 10 of 41 cases (24.4 %) and 11 of 65 SLNs (16.9 %) by intraoperative pathological diagnosis. Three cases showed occult metastasis within a year after the primary operation. Specificity and negative predictive value were 76.9 % and 90.3 %, respectively. The cumulative 5-year regional recurrence-free rate was 89.7 % in 31 SLNB-negative patients. Five-year overall and disease-free survival rates were 86.9 % and 70.1 %, respectively, in the 41 cases with identified SLNs. CONCLUSION CTL offers acceptable results and appears likely to be effective in treating early-stage OSCC patients with low-invasive surgery. Further investigation is necessary to compare radioisotope-based methods.

Abstract
PURPOSE This study aimed to compare perioperative outcomes of robotic and laparoscopic transabdominal peritoneal repair (TAPP) for unilateral inguinal hernia. METHODS This single institutional retrospective cohort study used de-identified data of patients who underwent robotic TAPP (R-TAPP) or laparoscopic TAPP (L-TAPP) for unilateral inguinal hernia between January 1, 2016 and October 31, 2021. Two cohorts were propensity matched, and data were analyzed. The learning curve was evaluated in the R-TAPP group. RESULTS Among 938 patients analyzed, 704 were included. After propensity-score matching, 80 patients were included in each group. The difference in operative time between R-TAPP and L-TAPP groups was 10 min (99.5 and 89.5 min, p = 0.087); however, console/laparoscopic time was similar (67 and 66 min, p = 0.71). The dissection time for medial-type hernia in the R-TAPP group was marginally shorter than that in the L-TAPP group (17 and 27 min, p = 0.056); however, there was no difference for lateral-type hernia (38.5 and 40 min p = 0.37). Perioperative variables, including estimated blood loss, postoperative hospital stay, and postoperative pain, had no significant difference, and chronic pain, which needed medication or intervention, was not observed in each group. The number of cases needed to achieve plateau performance was 7-10 in the R-TAPP group. CONCLUSION This study suggests that R-TAPP was safely introduced, and its perioperative outcomes were not inferior to those of L-TAPP. A shorter dissection time for medial-type hernia might be due to the robot's advantages, and a fast-learning curve could help with the early standardization of the procedure.

Abstract
Hypoglossia-hypodactylia syndrome is an extremely rare congenital anomaly characterized by a hypoplastic mandible, absence of the lower incisors, hypoglossia, and a variable degree of absence of the digits and limbs, with a risk of dysarthria and dysphagia. We report the articulation function and the swallowing function of a patient with hypoglossia-hypodactylia syndrome who was followed up to eight years old. Our patient did not have feeding and swallowing disturbances. She did not have articulatory disturbance, including /t/ and /r/, of the sound articulated using a proglossis. In the future, it is necessary to have a plastic operation for abnormal adhesion of the lower lip and mandibular gingiva and depression on the lower lip, and distraction osteogenesis for micrognathia. Also, it will be necessary to continuously monitor for an articulatory disturbance until the child uses more words. Therefore, a long-term intervention with a multidisciplinary approach is necessary.

Abstract
An elemental diet (ED) reduces adverse effects of chemotherapy, including oral mucositis, in patients with cancer. However, the detailed mechanism(s) of the healing effects of an ED remains unclear. In the present study, the protective effects of the ED, Elental®, were examined against 5-fluorouracil (5-FU)-induced oral mucositis and salivary gland atrophy in mice. Mucositis was induced in female ICR mice by injection of 5-FU. The mice were orally administered Elental® (ED group) or saline (control group). After treatment, the mice body weight, salivary gland weight and the histological changes in the salivary gland granular duct area were monitored. The mice body weight remained stable in the ED group, but was significantly decreased in the control group. Moreover, the salivary gland weight was higher in the ED group compared with the control group. In addition, the salivary gland granular duct area cells were larger in the ED group compared with the control group. Whole transcriptome analysis and network analysis were conducted to understand the mechanisms of action of Elental® against oral mucositis. Whole transcriptome analysis and Ingenuity Pathways Analysis data suggested that Elental® contributed to the recovery of mitochondrial function in 5-FU-damaged salivary glands. Immunohistochemical analysis of salivary gland tissue demonstrated that the expression of cytochrome c oxidase subunit 4 and epidermal growth factor were higher in the ED group compared with the control group. Next, the rate of apoptosis in the salivary glands was examined using terminal deoxynucleotidyl transferase-mediated nick end labeling (TUNEL) assays. The number of TUNEL-positive cells in the salivary glands was lower in the ED group compared with the control group. These findings suggested that Elental® may protect mouse salivary glands from 5-FU-induced atrophic changes, which suggests that ED treatment may improve xerostomia and alleviate oral mucositis in patients with cancer receiving 5-FU-based chemotherapy.

Abstract
BACKGROUND/AIM This study aimed to identify the most useful components of Elental® in the treatment of 5-fluorouracil (FU)-induced mucositis and salivary gland atrophy in mice. MATERIALS AND METHODS Mice (except the control group) were intraperitoneally injected with 5-FU. The mice received saline (control group and 5-FU group), dextrin (Dextrin group), amino acids (17AA group), or Elental® (Elental® group). RESULTS The volume and weight of salivary glands was higher in 17AA and Elental® groups compared to 5-FU group. The number of mucous glands was higher, whereas the number of damaged granular ductal epithelial cells was lower in the salivary glands of all groups except the 5-FU group. Salivation was also decreased in the 5-FU group compared to the other groups. CONCLUSION Amino acids could be the most effective components of Elental® for protecting mouse salivary glands from 5-FU-induced atrophic changes, and might be useful in the treatment of oral mucositis in cancer patients.

Abstract
BACKGROUND TAS-102 is effective against unresectable advanced or recurrent colorectal and gastric cancer. However, its effect on oral squamous cell carcinoma (OSCC) is still unknown. Here, we tried to clarify the possible effect of TAS-102 against angiogenesis and proliferation of human OSCC cells. MATERIALS AND METHODS 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay, migration assay and mice xenograft models were used to determine the effect of TAS-102 on growth and migration of OSCC. The activity of phosphorylated nuclear factor kappa light-chain-enhancer of activated B-cells (NF-κB) (p-p65) in cells was detected by immunocytochemistry. The expression of p-AKT serine/threonine kinase 1 (p-AKT), p-p65, vascular endothelial growth factor (VEGF), fibroblast growth factor (FGF2) and CD31 in mouse tumors were detected by immunohistochemistry. RESULTS TAS-102 significantly inhibited growth and migration of OSCC both in vitro and in vivo. It suppressed the activity of NF-κB in cells. TAS-102 down-regulated the expression of p-AKT, VEGF, FGF2 and CD31, which was associated with reduced vascularization of HSC2 tumor lesions. CONCLUSION These findings suggest that TAS-102 might inhibit angiogenesis and proliferation of OSCC cells.

Abstract
Vascular endothelial growth factor (VEGF) serves an important role in new blood vessel formation or angiogenesis, which is a critical event in tumor growth and metastasis. Bevacizumab is a humanized monoclonal antibody against VEGF-A, whereas S-1 is a fluoropyrimidine antineoplastic agent that induces apoptosis in various types of cancer cells. The present study evaluated the antitumor effects of bevacizumab in combination with 5-fluorouracil (5-FU) or S-1 against oral squamous cell carcinoma (OSCC) in vitro and in vivo. Two human OSCC cell lines were used, namely the high VEGF-A-expressing HSC-2 cells and the low VEGF-A-expressing SAS cells. MTT assay was used to evaluate the effect of bevacizumab and/or 5-FU against HSC-2 and SAS cell proliferation. Additionally, the antitumor effect of bevacizumab was evaluated alone and in combination with S-1 against HSC-2 tumors in nude mice. S-1 (6.9 mg/kg/day) was administered orally every day for 3 weeks, and bevacizumab (5 ml/kg/day) was injected intraperitoneally twice per week for 3 weeks. Apoptotic cells in mouse tumors were detected using the TUNEL method, and cell proliferation and microvessel density (MVD) were determined by immunohistochemical staining of Ki-67 and CD31, respectively. Bevacizumab alone did not inhibit OSCC cell proliferation in vitro, and did not exhibit any synergistic inhibitory effect in combination with 5-FU in vitro. However, combined bevacizumab and S-1 therapy exerted synergistic and significant antitumor effects in vivo on HSC-2 tumor xenografts, and induced apoptosis in tumor cells. Furthermore, this combination therapy led to decreased MVD and cell proliferative abilities, as well as increased apoptosis in residual tumors. The present findings suggested that the bevacizumab plus S-1 combination therapy may exert antitumor effects in high VEGF-A-expressing OSCC cells.

Abstract
Background:In the idividuals with genetic and enviromental risk factors, immune events at mucosal surfaces occur and may precede systemic autoimmunity. Anti-citrullinated protein antibodies (ACPA) are present in the serum for an average of 3-5 years prior to the onset of rheumatoid arthritis (RA) during an asymptomatic period. In ACPA-positivite individuals, the additional presence of RA-related risk factors appears to add significant power for the development of RA. To date, there have been few reports in which clinical courses of ACPA-positive asymptomatic individuals were investigated prospectively.Objectives:To observe the clinical time course of ACPA-positive healthy population for the development of RA.Methods:Healthy volunteers without joint pain or stiffness, who attended the comprehensive health screening of our hospital, were enrolled in this prospective observational study. The serum ACPA levels were quantified by Ig-G anti-cyclic citrullinated peptide enzyme-linked immunosorbent assay with levels > 4.4 U/mL considered positive. ACPA-positive subjects were followed by rheumatologists of our department clinically or a questionnaire sent by mail for screening to detect arthritis.Results:5,971 healthy individuals without joint symptons were included. Ninty-two (1.5%) were positive for ACPA. Of these, 19 (20.7%) developed RA and two were suspected as RA by mail questionnaire. Their average age were 58-years, and women were 68%. The average duration between the date of serum sampling and diagnosis was 10.7 months. ACPA-positive individuals who developed to RA had higher serum ACPA and Ig-M rheumatoid factor levels than ACPA-positive individuals who did not (P value by Mann-Whitney U test: 0.002, 0.005, respectively).Conclusion:Among ACPA-positive asymptomatic individuals, 20% developed RA. The higher titer of ACPA and Ig-M rheumatoid factor levels are risk factors for devoloping RA.Disclosure of Interests:None declared

Abstract
Background: Fusobacterium nucleatum, which is associated with periodontitis and gingivitis, has been detected in colorectal cancer (CRC). Methods: We evaluated the bactericidal effect of deep ultraviolet (DUV) light-emitting diode (LED) light therapy on F. nucleatum both qualitatively and quantitatively. Two DUV-LEDs with peak wavelengths of 265 and 280-nm were used. DNA damage to F. nucleatum was evaluated by the production of cyclobutane pyrimidine dimers (CPD) and pyrimidine (6–4) pyrimidone photoproducts (6–4PP). Results: DUV-LEDs showed a bactericidal effect on F. nucleatum. No colony growth was observed after 3 min of either 265 nm or 280 nm DUV-LED irradiation. The survival rates of F. nucleatum under 265 nm DUV-LED light irradiation dropped to 0.0014% for 10 s and to 0% for 20 s irradiation. Similarly, the survival rate of F. nucleatum under 280 nm DUV-LED light irradiation dropped to 0.00044% for 10 s and 0% for 20 s irradiation. The irradiance at the distance of 35 mm from the DUV-LED was 0.265 mW/cm2 for the 265 nm LED and 0.415 mW/cm2 for the 280 nm LED. Thus, the radiant energy for lethality was 5.3 mJ/cm2 for the 265 nm LED and 8.3 mJ/cm2 for the 280 nm LED. Amounts of CPD and 6–4PP in F. nucleatum irradiated with 265 nm DUV-LED light were 6.548 ng/µg and 1.333 ng/µg, respectively. Conclusions: DUV-LED light exerted a bactericidal effect on F. nucleatum by causing the formation of pyrimidine dimers indicative of DNA damage. Thus, DUV-LED light therapy may have the potential to prevent CRC.

Abstract
The effectiveness of an elemental diet (ED), Elental®, against radiotherapy‑ or chemoradiotherapy‑induced oral mucositis was previously reported. However, the administration of additional nutrition or an ED in patients with oral cancer may also provide extra nutrition for cancer cells, which could result in cancer development. At present, it remains unclear whether the beneficial effects of an ED are likely to surpass its potential harmful effects on oral cancer treatment. In the present study, we aimed to clarify whether Elental® has different effects on a healthy human oral keratinocyte (HOK) cell line compared with its effects on oral squamous cell carcinoma (OSCC) cell lines (HSC2, HSC3, HSC4). The efficacy of Elental® was compared in relation to the growth and migration ability of HOK and OSCC cell lines using MTT assay and migration assay, respectively. In addition, whole transcriptome analysis and network analysis were performed to determine the difference in the mechanism of action of Elental® between HOK and HSC2 cells. In addition, Elental® promoted growth and migration ability of‑malnourished and 5‑fluorouracil (5‑FU)‑treated damaged HOK cells cultured in low nutrition medium (0% growth supplement). However, Elental® did not affect the growth ability of 5‑FU‑treated damaged HSC2 cell line in low nutrition medium (0 or 1% fetal bovine serum (FBS), as well as the growth ability of HSC3 and HSC4 cell lines in medium containing 0% FBS. Elental® pre‑treatment also enhanced the apoptosis‑inducing effect of anticancer agents against OSCC cells. In addition, whole transcriptome analysis and Ingenuity Pathways Analysis (IPA) data suggested that Elental® may help in the proliferation and survival of HOK through the induction of ERK. Moreover, Elental® added stress to HSC2 cells through the induction of the endoplasmic reticulum stress response marker, BiP and GRP 94. The results showed that Elental® may add stress to HSC2 cells and provide growth stimulation to HOK. These findings suggest that the effects of Elental® on healthy oral cells and oral cancer cells may differ.

Abstract
Study objectives Niemann-Pick type C (NPC) is an autosomal recessive and congenital neurological disorder characterized by the accumulation of cholesterol and glycosphingolipids. Symptoms include hepatosplenomegaly, vertical supranuclear saccadic palsy, ataxia, dystonia, and dementia. Some cases frequently display narcolepsy-like symptoms, including cataplexy which was reported in 26% of all NPC patients and was more often recorded among late-infantile onset (50%) and juvenile onset (38%) patients. In this current study, we examined CSF orexin levels in the 10 patients of NPC with and without cataplexy, which supports previous findings. Methods Ten patients with NPC were included in the study (5 males and 5 females). NPC diagnosis was biochemically confirmed in all 10 patients, from which 8 patients with NPC1 gene were identified. We compared CSF orexin levels among NPC, narcoleptic and idiopathic hypersomnia patients. Results Six NPC patients with cataplexy had low or intermediate orexin levels. In 4 cases without cataplexy, their orexin levels were normal. In 5 cases with Miglustat treatment, their symptoms stabilized or improved. For cases without Miglustat treatment, their conditions worsened generally. The CSF orexin levels of NPC patients were significantly higher than those of patients with narcolepsy-cataplexy and lower than those of patients with idiopathic hypersomnia, which was considered as the control group with normal CSF orexin levels. Discussion Our study indicates that orexin level measurements can be an early alert of potential NPC. Low or intermediate orexin levels could further decrease due to reduction in the neuronal function in the orexin system, accelerating the patients’ NPC pathophysiology. However with Miglustat treatment, the orexin levels stabilized or improved, along with other general symptoms. Although the circuitry is unclear, this supports that orexin system is indeed involved in narcolepsy-cataplexy in NPC patients. Conclusion The NPC patients with cataplexy had low or intermediate orexin levels. In the cases without cataplexy, their orexin levels were normal. Our study suggests that orexin measurements can serve as an early alert for potential NPC; furthermore, they could be a marker of therapy monitoring during a treatment.

Abstract
Elental® is an L-glutamine-rich elemental diet (ED) that has been widely used in Japan as a nutritional supplement for malnourished patients. In addition, Elental® has been successfully used in the management of chemotherapy-induced mucositis in cancer patients. Recently, it was also reported that Elental® can effectively reduce chemotherapy-induced oral mucositis in patients with oral squamous cell carcinoma, and can also reduce mucositis and dermatitis in animal models. However, it is unclear whether oral intake or topical application of Elental® can act directly on chemotherapy-induced oral mucositis or dermatitis. The aim of the present study was to investigate the possible direct healing effect of Elental® on chemotherapy-induced dermatitis and raw wound areas in a mouse model. Dermatitis and raw wounds were induced in nude mice by administration of 5-fluorouracil (5-FU) (via gastric tube) and mechanical injury (using a metal brush or a surgical knife). We then compared the outcome following oral or topical application of Elental® in these mice. The effect of Elental® on the growth and migration ability of the human oral keratinocyte cell line, HOK, was also examined using MTT and migration assays, respectively. In the mouse model, both oral administration and topical application of Elental® reduced 5-FU-induced dermatitis and healed raw wound areas more effectively compared with the topical application of saline. The MTT assay revealed that Elental® exerted a growth-promoting effect on HOKs. In addition, Elental® enhanced the ability of HOKs to migrate, as demonstrated by the migration assay. These findings demonstrated that the topical application as well as the oral intake of Elental® exerted a direct healing effect on chemotherapy-induced dermatitis or raw wound areas. The data also indicated that oral intake of an ED may exert a direct healing effect on chemotherapy-induced oral mucositis.

Abstract
Background:Denosumab, a fully human monoclonal antibody to receptor activator of nuclear factor kappa B ligand, which inhibits osteoclast differentiation, activation and survival, not only increases bone mineral density but also inhibits the progression of bone erosion in patients with rheumatoid arthritis (RA)1-3). Therefore, denosumab have been preferably prescribed for patients with RA recently. The persistence with denosumab, which is administered subcutaneously once every 6 months, was reported higher than with oral bisphosphonates4), and in the prospective cohort studies, the persistence rate for one year was reported to be 82-95%5-6). However, there have been no report about the persistence in patients with RA treated with denosumab, moreover the reasons for discontinuation of denosumab.Objectives:The aims of this single center retrospective cohort study were 1) to assess the persistence with denosumab in a routine clinical setting and 2) to identify the reasons of discontinuation in patients with RA. And we also reviewed the clinical outcomes of osteonecrosis of the jaw in patients with RA during denosumab treatment.Methods:The present study is based on databases from our hospital, which include age, gender, date of injection of denosumab, as well as information on patients’ characteristics. Patients were included in this study when denosumab were newly started at our department during the period from June 1, 2013 and September 30, 2017. In this study, persistence was defined as patients with an interval between injections of no longer than 6 months plus 8 weeks. Patients were followed until censoring (death, transferring to another hospital) or the end of the study (August 3, 2018).We investigated reasons for the discontinuation of denosumab. Major reasons for the discontinuation of denosumab were classified as adverse event, anxiety over adverse events, patient’s transfer or request, doctor’s careless lack of refilling an injection, and other reason.We identified patients who had been diagnosed as osteonecrosis of the jaw, and demographic, pharmacological, and clinical data were collected from medical records.Results:One hundred and seventy-five patients were identified. Kaplan–Meier analysis showed a slow decline of persistence after initiating denosumab therapy, dropping to 80.4 and 61.9 % after 1 and 2 years of follow-up. When analyzing the reason of discontinuation as adverse events, the persistence rate of denosumab was at 89.4, and 79.4% at 1, and 2 years of follow-up, respectively.During 2-year period, 72 patients discontinued denosumab. A total of 27 adverse events occurred, of which five events were osteonecrosis of the jaw. The other reasons for adverse event included death in four, fracture in three, and so on. Six patients discontinued due to anxiety over dental adverse event. Thirteen patients were in doctor’s careless lack of refilling an injectionAll five patients who were diagnosed as osteonecrosis of the jaw had received the treatment with prednisolone, and four were treated with biologic drugs. All patients stopped denosumab and switched to other drugs including teriparatide. All patients underwent surgical curettages of necrotic bone and cured.Conclusion:Persistence of denosumab in patients with RA is comparable to that in postmenopausal women with osteoporosis. Dental screening and care should be important to continue denosumab treatment.References:[1]Cohen SB.Arthritis Rheum. 2008;58:1299–1309.[2]Takeuchi T.Ann Rheum Dis. 2019;78:899–907.[3]Ebina K.Osteoporos Int. 2018;29:1627–1636.[4]Hadji P.Osteoporos Int. 2016;27:2967–2978.[5]Silverman SL.Arch Osteoporos. 2018;13:85. doi:10.1007/s11657-018-0491-z[6]Hadji P.Osteoporos Int. 2015;26:2479–2489.Disclosure of Interests:Shinichi Mizuki Speakers bureau: AbbVie, Asahi Kasei, Chugai, Eli Lilly, Janssen, Mitsubishi Tanabe, Ono, Tatsuya Kai: None declared, Koji Mishima: None declared, Hiroko Ikeuchi: None declared, Kensuke Oryoji: None declared

Abstract
Introduction
Recently, attention has been paid to the relationship between developmental disorders such as attention deficit hyperactivity disorder (ADHD) and autism spectrum disorder (ASD), and sleep disorders. We meet many developmental disorder patients who complaint hypersomnolence. Among these patients, cases with coexistence of central hypersomnia and developmental disorders, or developmental disorder alone were increased. Therefore, we first investigated patients with the complaint of hypersomnolence, who were also suspected developmental disorders. Furthermore, we have been measuring CSF orexin in 17 cases suspected of both disorders to investigate orexin levels of these patients.
Methods
86patients who complained of EDS with suspicion of developmental disorders had been examined. In order to diagnose hypersomnolence disorders, PSG and MSLT were performed. Psychological examinations were performed for diagnosing developmental disorders.We have been measuring for CSF orexin in 17 cases suspected both hypersomnolence and developmental disorders. We examined the onset of hypersomnolence and the clinical history of these ADHD or ASD cases for more details.
Results
In 86 examined cases, developmental disorders coexisted in 30 cases. Among 30 cases, ADHD were 18, ASD were 6 and both diagnosed were 6 cases. Among them, 20 cases diagnosed as having coexistence of hypersomnia (8: narcolepsy, 12: IHS) and developmental disorders (ADHD:12, ASD:4, ADHD/ASD:4). In 17 cases with orexin measurements, 10 cases coexisted ADHD and 4 cases coexisted ASD. Two cases diagnosed as both ADHD and ASD. In 10 ADHD cases, 3 cases had low orexin levels, and 7 cases had normal orexin levels. Other 7 ASD cases had normal orexin levels.
Conclusion
ADHD has a higher rate of central hypersomnia (12/18) compared with ASD and the rate of narcolepsy was also high (5/12). While patients in ASD was diagnosed as IHS (3/6), narcolepsy cases were not observed. It became clear that the majority of patients had developmental disorder or had a tendency for developmental disorder before the onset of hypersomnolence.Although it is possible that ADHD/ASD symptoms may be exacerbated by orexin dysfunctions, ADHD/ASD may not newly occur. There were cases with low orexin levels, but it seems that narcolepsy happened to coexist with developmental disorders.

Abstract
OBJECTIVE In the field of forensic science, sex discrimination of skeletons is an important identification item for personal identification. The individual sex discrimination method using skeletons includes a determination method using measurement values and a macroscopic form observation method. Both methods have advantage and disadvantage. In this study, we used the homologous model technique and principal component (PC) analysis to determine gender difference from morphology of the mandible. METHODS AND MATERIALS 45 patients (23 males and 22 females) of CT imaging for tooth extraction from January 2018 to March 2019 at department of oral surgery, Osaka Medical College. The mean age was 43.1 ± 14.6. Patients with less than 14 remaining teeth were excluded because the number of remaining teeth may affect the shape of the mandible. 3D images were constructed, and 20 landmarks plotting on the 3D model surfaces. We generated template models of the mandible consisting of approximately 8434 polygons. The template model automatically fitted into the individually scanned point cloud of the mandible by minimising external and internal energy functions. As described above, the mandibles were constructed for each sample by using the Homologous Body Modeling software (HBM, Digital Human Technology, Inc.) and the mHBM-Rugle (Medic Engineering Corporation). The mandibles were analysed using the PCA. RESULTS The contribution of the most important PC was found to be 27.2%. 12 PCs explained over 75% of the total variance. That is, it was able to express 75% or more of the mandible expression with 12 PCs. A significant difference between male and female was observed in the first PCs (Wilcoxon test, p < 0.05). Visualising the result of the first PC showed that the mandibular branch of male was larger than that of female, and the mandible angle was overhanging outside. CONCLUSION This method is a combination of the determination method using the previous measurement values and the determination using macroscopic observation, and is considered to be innovative method.

Abstract
Abstract
BACKGROUND
Activation of telomerase plays a critical role in tumor development. Somatic alterations in the promoter of the telomerase reverse transcriptase (TERT) gene are a major mechanism of upregulating telomerase. Several mechanisms have been associated with TERT abnormalities, including TERT promoter mutations or methylation. Mutations in the TERT promoter have been observed in a subset of brain tumors, especially in adult gliomas. In pituitary adenomas (PAs), however, TERT abnormalities are not fully understood. The present study aimed to investigate not only mutational but also methylation status changes in the TERT promoter in PAs and to analyze their correlations with clinical variables.
MATERIAL AND METHODS
We retrospectively studied 70 PAs consisting of 53 primary and 17 recurrent samples. Clinical data, including age at surgery, sex, tumor size, tumor subtype, resection rate, presence or absence of postoperative irradiation, and progression-free survival (PFS), were obtained from medical records. First, we investigated TERT promoter hotspot mutations via Sanger sequencing. Next, we quantified the methylation status of the TERT promoter using methylation-sensitive high-resolution melting analysis (MS-HRM). Finally, we investigated TERT mRNA expression levels using real-time quantitative PCR. Fisher’s exact test was applied to evaluate the statistical significance between TERT promoter methylation status and tumor recurrence. PFS was calculated using Kaplan-Meier estimates and compared between methylated with ummethylated PAs with the log-rank test. The correlation between TERT promoter methylation status and mRNA levels was analyzed with the Mann-Whitney U-test. PFS was analyzed using multivariate analysis with the Cox proportional hazards model and included the following variables: age, sex, tumor size, tumor subtype, resection rate, radiation therapy, and methylation status.
RESULTS
TERT promoter hotspot mutations were not observed in any PA sample. Nineteen percent of PAs exhibitedTERT promoter methylation, which was significantly predominant in recurrent PA samples. PFS was significantly shorter in the methylated cases than in the unmethylated cases. Higher TERT expression levels were correlated with methylation status.
CONCLUSION
We found that TERT promoter methylation upregulated TERT expression and was associated with shorter PFS in PAs. Our results suggest thatTERT promoter methylation may be a potential biomarker for predicting tumor recurrence in PAs.

Abstract
Abstract
BACKGROUND
The addition of high-dose methotrexate (HD-MTX)-based chemotherapy to whole brain irradiation (WBRT) has improved the prognosis of primary central nervous system lymphoma (PCNSL). However, the high neurotoxicity rates observed, especially in the elderly, raised interest in chemotherapy-only treatments. Withholding radiotherapy substantially decreases the risk of neurotoxicity, however, disease control may be compromised. Therefore, developing a novel treatment for the elderly PCNSL patients (ePCNSL) is crucial. In the elderly who cannot tolerate WBRT as a consolidation, maintenance treatment may serve as a feasible approach after an initial response. We treated ePCNSL with induction immunochemotherapy with rituximab (RIT) and HD-MTX, maintenance chemotherapy with HD-MTX and deferred WBRT. Here, we retrospectively investigated the prognosis for ePCNSL that became CR after the induction chemotherapy.
MATERIAL AND METHODS
Newly diagnosed ePCNSL (median age: 74 years) received biweekly RIT/ HD-MTX (375 mg/m2/dose; 3.5g/m2/dose) for 6 cycles (induction) followed by monthly RIT/MTX for 2 cycles (consolidation) and then were treated differently according to the radiological response. With CR patients, HD-MTX was continued with every 3 months (maintenance) for 2 years. Patients who did not obtain consent for maintenance therapy were followed up.
RESULTS
Of the 42 ePCNSL (median age 74 years), 26 had CR after induction and consolidation, of which 18 cases were carried out maintenance (M +) and 8 cases were followed up (M-). The median age was 74 and 76, respectively. Median progression-free survival (mPFS) was 73 months in the M+ group and 24.6 months in the M- group. Median overall survival (mOS) is 92.5 months versus 27.6 months, respectively. Both mPFS (P= 0.025) and mOS (P =0.0003) were significantly prolonged by maintenance therapy. In addition, ePCNSL with tumors involvement of deep brain structure had a poor prognosis.
CONCLUSION
It was suggested that maintenance treatment with HD-MTX may improve the prognosis for ePCNSL that reached complete response after induction therapy.

Abstract
BACKGROUND Russell-Silver syndrome (RSS) is characterized by intrauterine growth retardation, short stature without postnatal catch-up growth, and an inverted triangular face with relative macrocephaly. There have been few case reports of RSS with cleft palate, in which perioperative problems such as difficult intubation due to trismus and impossibility to wear a mouth gag due to growth failure of the mandible were described. The case of a female RSS patient with cleft palate who underwent palatoplasty is reported. CASE PRESENTATION Although her weight was particularly low (5920 g), palatoplasty was performed under general anesthesia at 3 years and 6 months of age. Despite limited mouth opening, intubation was relatively easy. Although her mandibular alveolar width was narrow, a Dingman mouth gag could be tightly fastened around her mouth. Postoperatively, the patient was transferred to the intensive care unit without extubation due to pharyngeal edema. On the following day, since the pharyngeal edema had improved, the endotracheal tube was extubated, and her respiratory status was subsequently stable. CONCLUSIONS In RSS patients with cleft palate, there have been a few reports of pharyngeal edema. Thus, the risk of pharyngeal edema must be considered in such patients.

Abstract
Oral mucositis is a common adverse effect of cancer treatment that can increase the risk for local and systemic infection. This prospective study was designed to evaluate the preventive effects of an amino-acid-rich elemental diet (ED), Elental®, on radiotherapy- or chemoradiotherapy-induced mucositis in oral squamous cell carcinoma (OSCC) patients. Fifty patients were enrolled in this prospective study, who had received radiation (60-70 Gy) with/without chemotherapy [S-1, UFT, cisplatin (CDDP), docetaxel (DOC) plus CDDP, or Cetuximab]. The Elental® group (25 patients) had received Elental® during treatment, and the control group (25 patients) had not. Multivariate logistic regression analysis was used to identify the factors related to abatement of oral mucositis. A comparison of the rates of completion of chemoradiation treatments as well as the nutritional or inflammatory status between Elental® and control groups was performed. Multivariate analysis indicated that most of the patients who received Elental® suffered from a lower degree of mucositis and showed significantly improved rate of completion of chemoradiation (no interruption) compared to the control group. There was a significant difference between the Elental® group and the control group in terms of the mean change of C-reactive protein (CRP) levels in blood serum; however, there was no significant difference in terms of a mean change of body weight and total protein level in blood serum before and after chemoradiation. Our study shows that the Elental® elemental diet could be useful for the treatment of oral mucositis induced by chemoradiation. Elental® might also promote improved completion rates of chemoradiotherapy in OSCC patients.

Abstract
Forkhead box protein M1 (FOXM1) is an oncoprotein that is involved in cell proliferation, differentiation and aging, and overexpression of FOXM1 is thought to be associated with the development and progression of various types of cancer. The expression of FOXM1 was retrospectively examined in tumor tissues taken from 56 oral squamous cell carcinoma (OSCC) patients by immunohistochemical staining. All of these patients received docetaxel (Doc)-containing regimens as treatments against OSCC. The association between FOXM1 expression and the clinicopathological characteristics and prognosis of these patients was then examined. FOXM1 was expressed in the nucleus and cytoplasm of OSCC tissues samples. There was a significant association between FOXM1 expression in tumor tissues and N classification (P=0.0395), stage (P=0.004), therapeutic efficacy (P=0.0113) and outcome (P=0.0134) of patients. However, FOXM1 expression had no association with patients' sex, age or T classification. Additionally, high expression of FOXM1 in tumor cells was associated with a shorter overall survival (P=0.0257) of patients. Multivariate analysis also revealed that elevated expression of FOXM1 was a predictor of patients' poor survival (P=0.0327). The results suggested that high expression of FOXM1 in OSCC tumors may result in reduced therapeutic effects and poor clinical outcomes of patients receiving Doc-based treatment regimens.

Abstract
An elemental diet (ED) has been reported to reduce oral mucositis and dermatitis induced by chemotherapy. However, its molecular mechanism of action as an anti‑inflammatory agent is still unknown. The aim of the present study was to clarify whether ED confers its anti‑inflammatory action via reduction of pro‑inflammatory cytokine production in keratinocytes in vivo and in vitro. We evaluated the efficacy of ED in the treatment of 5‑fluorouracil (5‑FU)‑induced dermatitis of nude mice, and examined the expression of pro‑inflammatory cytokines such as tumor necrosis factor‑α (TNF‑α), interleukin (IL)‑1β and IL‑6 using immunohistochemistry. Moreover, we assessed the expression and production of these pro‑inflammatory cytokines by western blotting and ELISA assays, respectively, in immortalized human keratinocyte cell line, HaCaT. Furthermore, we investigated the effect of ED on a major inflammation‑related factor, nuclear transcription factor‑κB (NF‑κB), since it controls many genes involved in the inflammation pathway. Our results indicated that ED reduced the expression of TNF‑α, IL‑1β and IL‑6. It also inhibited the nuclear transition of p65 NF‑κB, which is known to regulate inflammatory cytokine expression in keratinocytes suffering from 5‑FU‑induced dermatitis. In addition, ED reduced the production of TNF‑α, IL‑1β and IL‑6 in HaCaT cells. Moreover, ED attenuated 5‑FU‑induced transcriptional activation of NF‑κB. These findings revealed that ED suppresses the expression of pro‑inflammatory cytokines by suppressing NF‑κB in keratinocytes, suggesting the potential usefulness of ED in the treatment of various inflammatory diseases of the dermal region.

Abstract
Objective To evaluate the motion of the face and jaw of patients with cleft lip and palate, facial palsy, and in patients after reconstruction, a motion-analyzing system was developed. The aim of this article was to investigate the accuracy of this system and the possibility of clinical application. Methods Markers of 1 to 2 mm were placed on the face, and motion images were obtained by three digital video cameras controlled by a synchronizer and recorded on digital video tape. The image was processed on a personal computer. The markers were automatically tracked across the image sequences, and their three-dimensional coordinates were then calculated. Main Outcome Measures System accuracy was investigated using a positioning actuator with high accuracy and a known object. In three patients with bilateral cleft lip and palate, lip pursing was analyzed using the aforesaid method. Results and Conclusions The mean differences from the known values to the distances between the tracked sample points and to the mobile distances of the sample points per frame were 0.24 to 0.36 mm and 0.02 to 0.05 mm, respectively. Both results were similar regardless of the mobile speed or direction. In five repeated measurements, the mean differences from the known values as for the distances and the mobile speed ranged from 0.19 to 0.38 mm and from 0.00 to 0.07 mm, respectively. Examination of three patients with bilateral cleft lip and palate indicated the possibility that lip movement could be successfully analyzed using the present system.

Abstract
BACKGROUND/AIM To evaluate the efficacy of palonosetron in preventing acute and delayed nausea and vomiting in patients receiving highly emetogenic chemotherapy (HEC) in oral cancer patients. PATIENTS AND METHODS Oral cancer patients receiving HEC were enrolled; among the 40 patients, 87 courses of chemotherapy were administered. On day 1, 0.75 mg palonosetron was intravenously administrated just before chemotherapy. RESULTS The primary endpoint was the proportion of patients with a complete response (CR) and the secondary endpoint was the proportion of patients with complete control (CC) during the acute and delayed phase. During the acute phase, 86 of 87 courses (98.9%) had CR and 84 of 87 courses (96.6%) had CC. During the delayed phase, 84 of 87 courses (96.6%) had CR and 70 of 87 courses (80.5%) had CC. CONCLUSION Palonosetron is effective at preventing HEC-induced chemotherapy-induced nausea and vomiting (CINV) in oral cancer chemotherapeutic regimens in the acute and delayed phases.

Abstract
We evaluated the circadian phenotypes of patients with delayed sleep-wake phase disorder (DSWPD) and non-24-hour sleep-wake rhythm disorder (N24SWD), two different circadian rhythm sleep disorders (CRSDs) by measuring clock gene expression rhythms in fibroblast cells derived from individual patients. Bmal1-luciferase (Bmal1-luc) expression rhythms were measured in the primary fibroblast cells derived from skin biopsy samples of patients with DSWPD and N24SWD, as well as control subjects. The period length of the Bmal1-luc rhythm (in vitro period) was distributed normally and was 22.80±0.47 (mean±s.d.) h in control-derived fibroblasts. The in vitro periods in DSWPD-derived fibroblasts and N24SWD-derived fibroblasts were 22.67±0.67 h and 23.18±0.70 h, respectively. The N24SWD group showed a significantly longer in vitro period than did the control or DSWPD group. Furthermore, in vitro period was associated with response to chronotherapy in the N24SWD group. Longer in vitro periods were observed in the non-responders (mean±s.d.: 23.59±0.89 h) compared with the responders (mean±s.d.: 22.97±0.47 h) in the N24SWD group. Our results indicate that prolonged circadian periods contribute to the onset and poor treatment outcome of N24SWD. In vitro rhythm assays could be useful for predicting circadian phenotypes and clinical prognosis in patients with CRSDs.

Abstract
Objectives: The purpose of this study was to develop a new technique for analyzing velopharyngeal movement and to investigate its utility. Materials and Methods: Velopharyngeal motion of 20 normal individuals was analyzed. A three-dimensional (3D) endoscope was inserted into the oral cavity, and the movement of the soft palate was measured using an exclusive fixation device. Range images of the soft palate were produced during phonation of the Japanese vowel /a/, and virtual grids were then overlaid on these images. Principal component analyses were applied to the 3D coordinates of the intersections of the virtual grids. The centers of gravity of the virtual grids were calculated, and the magnitude of the shift of the grid intersections during phonation was calculated. Results: The first and the second principal component scores were responsible for the upper posterior direction and the upper direction, respectively. The average magnitude of the shift of the center of gravity was 4.75 mm in males and 4.33 mm in females. Conclusions: Quantitative analysis of velopharyngeal movement was achieved by a method of applying principal component analysis (PCA) to the range images obtained from a 3D endoscope. There was no sex difference in velopharyngeal movement.

Abstract
An 18-year-old woman with mild Crouzon syndrome was referred with malocclusion and mandibular protrusion. Examination revealed Class III canine and molar relationships, hypoplastic maxilla, 1-mm overbite, and -2-mm overjet. Analysis showed 69° sella-nasion-A, 73.6° sella-nasion-B, and -4.6° A point-nasion-B point angles. Polysomnography revealed respiratory disturbance and 6.3% oxygen desaturation indices of 5.4/h and 9.0/h. We performed double-jaw surgery using high Le Fort I osteotomy and bilateral sagittal split ramus osteotomy for midfacial deformity correction. Twelve months post-surgery, her measures were 70.8°, 72°, -1.2°, 3.0/h, and 6.1/h, respectively. Esthetics were satisfactory. High Le Fort I osteotomy is effective for midfacial deformity correction in patients with Crouzon syndrome.

Abstract
Two cases where aberrant tissue was attached to the lower lip mimicking the inferior labial frenum were reported. The frenum-like tissue extended from the gingival margin between the lower left deciduous central and lateral incisors in case 1 and between the lower right deciduous central and lateral incisors in case 2, to the dry lower lip. Histologically, the resected specimen was regarded as normal oral mucosa covered with stratified squamous epithelium, without a clear amniotic band. The frenum-like tissue of the lower lip found in both our patients was diagnosed as a category of oral synechiae, of unknown origin.

Abstract
OBJECTIVE We developed a novel method of producing accurate range images of the velopharynx using a three-dimensional (3D) endoscope to obtain detailed measurements of velopharyngeal movements. The purpose of the present study was to determine the relationship between the distance from the endoscope to an object, elucidate the measurement accuracy along the temporal axes, and determine the degree of blurring when using a jig to fix the endoscope. METHODS An endoscopic measuring system was developed in which a pattern projection system was incorporated into a commercially available 3D endoscope. After correcting the distortion of the camera images, range images were produced using pattern projection to achieve stereo matching. Graph paper was used to measure the appropriate distance from the camera to an object, the mesial buccal cusp of the right maxillary first molar was measured to clarify the range image stability, and an electric actuator was used to evaluate the measurement accuracy along the temporal axes. RESULTS The measurement error was substantial when the distance from the camera to the subject was >6.5 cm. The standard error of the 3D coordinate value produced from 30 frames was within 0.1 mm (range, 0.01-0.08 mm). The measurement error of the temporal axes was 9.16% in the horizontal direction and 9.27% in the vertical direction. CONCLUSION The optimal distance from the camera to an object is <6.5 cm. The present endoscopic measuring system can provide stable range images of the velopharynx when using an appropriate fixation method and enables quantitative analysis of velopharyngeal movements.

Abstract
OBJECTIVES It is important to assess the mandibular morphology when orthognathic surgery, especially mandibular ramus osteotomy, is performed. Several studies on three-dimensional (3D) facial asymmetry have reported differences in linear and angle measurements between the deviated and contralateral sides in asymmetric mandibles. However, methods used in these studies cannot analyse the 3D morphology of the ramus. In this study, we aimed to evaluate the differences in mandibular ramus between the deviated and contralateral sides in asymmetric mandibles using traditional measurements as well as 3D shape analysis. METHODS 15 Japanese females with jaw deformities treated by orthodontic surgery were enrolled. 3D CT images were reconstructed, and 14 landmarks were identified on the model surface. Ten linear and four angle measurements were calculated using these landmarks. Homologous ramus models were constructed for each sample, and after converting all homologous models to the right side, 30 homologous models of the ramus were analysed using principal component analysis. RESULTS Firstly, eight principal components explained >80% of the total variance. Differences between the deviated and contralateral sides in measurements and scores of the eight principal components were tested. Significant difference at the 5% level between the deviated and contralateral sides was observed in five linear measurements, three angle measurements and the third principal component. The variance of the deviated side was significantly larger in the diameter between the mandibular notch and coronoid process, horizontal dilated angle of the mandibular ramus and vertical dilated angle of the mandibular ramus. The variance of the contralateral side was significantly larger in the height of mandibular ramus, height of posterior of mandibular ramus, condylar width, height of condylar head and mandibular angle. The squared multiple correlation coefficient adjusted for the degrees of freedom was 0.815. The third principal component showed the difference between the deviated and contralateral sides. Shape variation represented by the third principal component visually indicated that the contralateral side was larger and had inwardly directed coronoid process and the deviated side had a mandibular angle that was turned inwards to a greater extent. CONCLUSIONS In conclusion, we successfully created a homologous model of the mandibular ramus and demonstrated the effectiveness of this model in the 3D comparison of the ramus morphology between the contralateral and deviated sides in asymmetric mandibles.

Abstract
Squamous cell carcinoma throughout the epithelium of a lateral cervical cyst is considered extremely rare. This report describes an additional case of this very rare clinical condition. A 70-year-old man presented with a well-defined, immobile, painless mass in the left neck that was excised with a diagnosis of branchial cyst. Histologic findings of the excised specimen were lateral branchial cyst with high-grade dysplasia and carcinoma of the squamous epithelial lining. The patient was followed for more than 2 years 10 months and no evidence of recurrence or other cancer has been found.

Abstract
Salter innominate osteotomy is an effective reconstructive procedure for the treatment of developmental dysplasia of the hip (DDH), but some children have a poor outcome at skeletal maturity. In order to investigate factors associated with an unfavourable outcome, we assessed the development of the contralateral hip. We retrospectively reviewed 46 patients who underwent a unilateral Salter osteotomy at between five and seven years of age, with a mean follow-up of 10.3 years (7 to 20). The patients were divided into three groups according to the centre-edge angle (CEA) of the contralateral hip at skeletal maturity: normal (> 25°, 22 patients), borderline (20° to 25°, 17 patients) and dysplastic (< 20°, 7 patients). The CEA of the affected hip was measured pre-operatively, at eight to nine years of age, at 11 to 12 years of age and at skeletal maturity. The CEA of the affected hip was significantly smaller in the borderline and dysplastic groups at 11 and 12 years of age (p = 0.012) and at skeletal maturity (p = 0.017) than in the normal group. Severin group III was seen in two (11.8%) and four hips (57.1%) of the borderline and dysplastic groups, respectively (p < 0.001). Limited individual development of the acetabulum was associated with an unfavourable outcome following Salter osteotomy.
