Abstract
Background Patients with complete bilateral cleft lip and palate (CBCLP) have the most complex orofacial abnormalities despite its lowest incidence among cleft lip and palate (CLP) types. Impaired maxillary growth can result from surgical procedures in patients with CBCLP. This study evaluates dental arch relationships in Indonesian patients with CBCLP after undergoing CLP repair at Harapan Kita Children and Mother Hospital in Jakarta. Material and Methods Using the modified Huddart and Bodenham (MHB) index and Bauru bilateral cleft lip and palate (BCLP) yardstick, three examiners assessed 17 study models in the 9-year age group and 13 study models in the 12-year age group, as well as two intraoral clinical photographs of two patients with CBCLP. The assessments were repeated three times within two weeks of each assessment time. Results Patients with operated CBCLP (aged 9 and 12 years) had edge-to-edge tooth relations, which were categorized as a mild crossbite or mild deviation, and only required orthodontic treatment according to the two specified indicators. Conclusions The CLP repair protocol used at the Harapan Kita Hospital effectively manages CBCLP cases with satisfactory results, suggesting the effectiveness of the MHB index and Bauru-BCLP yardstick in assessing dental arch relationships in patients with operated CBCLP. Key words:Bilateral, cleft lip and palate, dental arch relationship, lip repair, palate repair.

Abstract
Phylogenetically, the tribosphenic molars-prototypes of multi-cusped cheek teeth in marsupial and placental mammals-are derived from the single-cusped conical teeth of reptiles through the addition of cusps. Ontogenetically, mammalian molars are formed through the interface between the dental epithelium and mesenchyme (future enamel-dentin junction), becoming geometrically complex by adding epithelial signaling centers, called enamel knots, which determine future cusp positions. To reevaluate cusp homologies in Mesozoic mammals from an ontogenetic perspective, this study tracked molar development in a living placental mammal species, the house shrew (Suncus murinus), whose molars are morphologically the least derived from tribosphenic prototypes. The development of shrew molars proceeded as if it replayed the evolutionary process of tribosphenic molars. The first formed enamel knots gave rise to the evolutionarily oldest cusps-upper paracone and lower protoconid. The order of formation of other enamel knots and their location in development seemed to trace the order of cusp appearance in evolution. The parallel relationship between ontogeny and phylogeny of mammalian molars, if any, suggests that a change in the timing between developmental events rather than a change in the morphogenetic mechanism itself, should have been a major causal factor for the evolutionary transformation of tooth morphology.

Abstract
OBJECTIVE To quantitatively assess three-dimensional (3D) soft tissue facial asymmetry in patients with unilateral cleft lip and palate (UCLP) who have undergone primary lip repair. DESIGN Clinical, retrospective, comparative, methodological study. PATIENTS/PARTICIPANTS Twenty patients with UCLP were selected after a review of the records. INCLUSION CRITERIA Complete UCLP; surgically treated without secondary repair. An age-matched and sex-matched Control group was employed. MAIN OUTCOME MEASURES A 3D facial symmetry plane (FSP) was obtained by superimposing the point clouds of the original 3D facial image excluding the surgical site and including lip and nose areas and those of a mirrored facial image using the iterative closest point (ICP) adjustment method. The discrepancies in the depth and angle of the normal vector of the facial surface of each point cloud between right and left sides (cleft and non-cleft sides in the UCLP group, respectively) based on FSP were calculated. RESULTS Facial asymmetry in the UCLP group was significantly greater than in the Control group regarding both the discrepancies in the depth (1.34 ± 0.62, 0.73 ± 0.32 pixels, respectively) (P = .0004) and surface angle (18.0 ± 5.88, 12.8 ± 4.0°, respectively) (P = .0024). Biaxial assessment of the discrepancies in the depth and surface angle allowed us to visually extract UCLP patients with greater facial asymmetry. CONCLUSIONS Facial asymmetry analysis based on 3D FSP effectively facilitates the facial asymmetry quantification and soft tissue surgical outcome evaluation in patients with UCLP.

Abstract
PURPOSE/OBJECTIVE(S) Clinical practice is not always performed in accordance with guideline recommendations. Quality indicators (QIs) are valuable tools for evaluating the quality of healthcare systems. We sought to identify potential gaps between clinical practice and evidence using QIs previously developed using a modified Delphi method. MATERIALS/METHODS We used seven QIs (Table 1) to assess the quality of radiation therapy for bone (BoM) and brain metastases (BrM) at 29 centers; 13 (45%) were academic (12 university hospitals and 1 cancer center) and 16 (55%) were nonacademic hospitals. Compliance rate was calculated as the percentage of patients for whom recommended medical care was conducted. Random effects models were used to estimate pooled compliance rates. Mixed effects models with a Q test were used to compare compliance rates between academic and nonacademic centers. RESULTS The estimates of the compliance rates with 95% confidence intervals are presented in Table 1. For BoM-1, the compliance rate was higher in academic hospitals (100% [100-100%]) than in non-academic hospitals (96% [89-100%]) (P = 0.021). For BrM-3, the compliance rate was lower in academic hospitals (92% [81-99%]) than in nonacademic hospitals (100% [98-100%]) (P = 0.016). CONCLUSION A quality assessment based on these seven QIs is feasible. Overall, compliance rates were high; however, for BoM-3, the practice remains to be improved in some centers. Based on BoM-4 compliance rates, steroids are infrequently used concurrently with radiation therapy for malignant spinal cord compression. Extended fractionation for BoM was less frequently performed in academic than in nonacademic centers. The initiation of radiation therapy for brain metastases was more frequently delayed in academic than in nonacademic centers.

Abstract
Bone morphogenic protein 9 (BMP9) is one of the most potent inducers of osteogenic differentiation among the 14 BMP members, but its mechanism of action has not been fully demonstrated. Hes1 is a transcriptional regulator with basic helix-loop-helix (bHLH) domain and is a well-known Notch effector. In this study, we investigated the functional roles of early induction of Hes1 by BMP9 in a mouse mesenchymal stem cell line, ST2. Hes1 mRNA was transiently and periodically induced by BMP9 in ST2, which was inhibited by BMP signal inhibitors but not by Notch inhibitor. Interestingly, Hes1 knockdown in ST2 by siRNA increased the expression of osteogenic differentiation markers such as Sp7 and Ibsp and matrix mineralization in comparison with control siRNA transfected ST2. In contrast, forced expression of Hes1 by using the Tet-On system suppressed the expression of osteogenic markers and matrix mineralization by BMP9. We also found that the early induction of Hes1 by BMP9 suppressed the expression of Alk1, an essential receptor for BMP9. In conclusion, BMP9 rapidly induces the expression of Hes1 via the SMAD pathway in ST2 cells, which plays a negative regulatory role in osteogenic differentiation of mesenchymal stem cells induced by BMP9.

Abstract
AIMS Although palliative radiotherapy for gastric cancer may improve some symptoms, it may also have a negative impact due to its toxicity. We investigated whether symptoms improved after radiotherapy with adjustment for the Palliative Prognostic Index (PPI) considering that patients with limited survival tend to experience deterioration of symptoms. MATERIALS AND METHODS This study was an exploratory analysis of the Japanese Radiation Oncology Study Group study (JROSG 17-3). We assessed six symptom scores (nausea, anorexia, fatigue, shortness of breath, pain at the irradiated area and distress) at registration and 2, 4 and 8 weeks thereafter. We tested whether symptoms linearly improved after adjusting for the baseline PPI. Shared parameter models were used to adjust for potential bias in missing data. RESULTS The present study analysed all 55 patients enrolled in JROSG 17-3. With time from registration as the only explanatory variable in the model, a significant linear decrease was observed in shortness of breath, pain and distress (slopes, -0.26, -0.22 and -0.19, respectively). Given that the interaction terms (i.e. PPI × time) were not significantly associated with symptom scores in any of the six symptoms, only PPI was included as the main effect in the final multivariable models. After adjusting for the PPI, shortness of breath, pain and distress significantly improved (slope, -0.25, -0.19 and -0.17; P < 0.001, 0.002 and 0.047, respectively). An improvement in fatigue and distress was observed only in patients treated with a biologically effective dose ≤14.4 Gy. CONCLUSION Shortness of breath, pain and distress improved after radiotherapy. Moreover, a higher PPI was significantly associated with higher symptom scores at all time points, including baseline. In contrast, PPI did not seem to influence the improvement of these symptoms. Regardless of the expected survival, patients receiving radiotherapy for gastric cancer can expect an improvement in shortness of breath, pain and distress over 8 weeks. Multiple-fraction radiotherapy might hamper the improvement in fatigue and distress by its toxicity or treatment burden.

Abstract
Background: Better prognostic biomarkers for oral squamous cell carcinoma (OSCC) must be developed, particularly within the realm of clinically and frequently administered tests, to advise appropriate clinical therapy and follow-up. In this study, we retrospectively investigated which of the several inflammation-nutrition indicators might predict the prognosis of patients with OSCC. Methods: The preoperative neutrophil-lymphocyte ratio (NLR), lymphocyte-monocyte ratio (LMR), platelet-lymphocyte ratio (PLR), CRP-albumin ratio (CAR), Glasgow prognostic score (GPS), modified GPS (mGPS), prognostic nutritional index (PNI), controlling nutrition status (CONUT), and modified CONUT (mCONUT) were retrospectively evaluated using blood samples collected 1-5 days before surgery. To estimate the effect on the prognosis of tumor progression, the mean values of the markers between stages I/II and III/IV were used for subgroup analysis. The multivariate Cox proportional hazards model included all independent variables significantly associated with survival in the univariate analysis to determine the independent variables. Results: A total of 112 patients (69 males and 43 females) with primary OSCC who underwent surgical treatment at our hospital were included. There were statistically significant differences in the mean values of monocytes, platelets, and albumin between stages I/II and III/IV. According to the multivariate Cox proportional hazards regression, a low PNI was associated with shorter overall survival (OS) and disease-free survival (DFS); women were associated with shorter DFS. Conclusion: The pretreatment PNI had excellent predictive value for the 5-year OS and DFS of patients with OSCC. Future large-scale prospective studies with a high sample size are needed to verify our findings in OSCC patients.

Abstract
Abstract
Background
Strut coverage of drug-eluting stents (DES) is one of the important factors for the duration of dual anti-platelets therapy (DAPT) after percutaneous coronary intervention. Several studies have reported percent coverage of struts assessed by optical coherence tomography (OCT), however, the timing of endothelial coverage of the latest second- and third-generation DES has not been revealed histologically.
Methods and results
From CVHills stent autopsy registry of 171 stented lesions, a total of 56 lesions from 39 autopsy cases with less than 370 days after second- and/or third-generation DES implantation was evaluated histologically. The lesions were stratified by duration: 1–30 days (n=39), 31–60 days (n=4), 61–90 days (n=5), 91–180 days (n=2), and 181–370 days (n=6), and percent coverage of struts, which was defined as neointimal coverage overlying with endothelial cells, was evaluated for each lesion. In addition, difference of coverage within 90 days after implantation between second-generation DES with circumferentially coated polymer and third-generation DES with abluminally coated polymer was also evaluated.
Percent strut coverage increased with time [1–30 days vs. 31–60 days vs. 61–90 days vs. 91–180 days vs. 181–370 days: median (interquartile range) 0.0% (0.0–0.3), 6.3% (1.0–11.7), 16.7% (8.0–32.6), 64.2% (55.6–72.9), and 86.5% (63.5–92.5), respectively, p<0.0001]. When the coverage at the earlier time point was compared between second- and third-generation DES, prevalence of coverage with >25% per section was higher in third-generation DES and the difference was more obvious in 61–90 days after stent implantation (0.0 vs. 1.0%, p=0.15 in 1–30 days, 7.7 vs. 14.3%, p=0.65 in 31–60 days, and 10.0 vs. 36.3%, p=0.04 in 61–90 days).
Conclusions
The current pathological analysis has demonstrated that the process of endothelial strut coverage in second- and third-generation DES proceeds over time, however, the speed was slower than reported in the previous studies evaluated with OCT. Furthermore, endothelial strut coverage of third-generation DES was faster than that of second-generation DES, suggesting a positive roll of abluminal coating on healthy endothelial coverage and safety de-escalation of DAPT at earlier timepoint.

Abstract
Abstract
Background
Poor below-the-knee (BTK) run-off is reported to be one of the predictors of stent failure after endovascular treatment to femoro-popliteal arteries (1), however, the mechanism of stent failure has never been characterized before. The aim of the current study was to evaluate impact of poor BTK run-off on stent failure in healthy swine femoro-popliteal (FP) lesions, and to compare the outcome of a bare-metal stent (BMS) and two drug-eluting stents (DES) in the arteries with poor BTK run-off.
Method
Fluoropolymer-coated paclitaxel-eluting stents (FP-PES, Eluvia) and BMS were implanted in bilateral femoral arteries of 6 healthy swine following coil embolization in both tibial arteries to induce poor BTK run-off. FP-PES and polymer-free paclitaxel-coated stents (PF-PCS, Zilver-PTX) were also implanted in 6 swine with the same fashion. Angiography with an optical coherence tomography (OCT) at one month followed by histological analysis was performed for each lesion.
Result
Angiography demonstrated that in-stent restenosis was observed exclusively in BMS, and percent stenosis was significantly less in FP-PES compared with BMS (FP-PES vs. BMS, median [interquartile range (IQR)], 17.8% [16.6–28.7] vs. 79.3% [64.2–87.2], respectively, p=0.03). FP-PES also demonstrated significantly less percent stenosis compared with PF-PCS (FP-PES vs. PF-PCS, 8.9% [4.7–44.7] vs. 31.2% [23.3–51.2], respectively, p=0.03). Histopathological evaluation demonstrated that organizing and/or organized fibrin thrombus was the main feature of the restenotic lesions, suggesting a risk of thrombus attachment in the FP lesions with poor BTK run-off. Biologic drug effect such as medial smooth muscle cell (SMC) loss score was significantly greater in FP-PES compared with BMS (4.0 [3.3–4.0] vs. 2.0 [1.0–3.0], respectively, p<0.01), whereas, similar between FP-PES and PF-PCS (4.0 [3.0–4.0] vs. 4.0 [3.0–4.0], respectively, p=0.88).
Conclusion
Thrombus attachment would be the main causes of restenosis in FP lesions with poor BTK runoff. The results of the current study suggest that not only paclitaxel drug effect, but also anti-thrombotic effect of fluoropolymer might be needed to prevent stent failure.

Abstract
Ameloblastoma is an odontogenic tumor located in the bone jaw with clinical characteristics of extensive bone resorption. It is a locally invasive tumor with a high recurrence rate despite adequate surgical removal. In bone disease, tumors and other cells including osteoblasts, osteoclasts, and osteocytes in the bone microenvironment contribute to the pathogenesis of tumor growth. However, the effect of osteoblasts on ameloblastoma cells is not well-understood, and there has been limited research on interactions between them. This study investigated interactions between ameloblastoma cells and osteoblasts using a human ameloblastoma cell line (AM-3 ameloblastoma cells) and a murine pre-osteoblast cell line (MC3T3-E1 cells). We treated each cell type with the conditioned medium by the other cell type. We analyzed the effect on cytokine production by MC3T3-E1 cells and the production of MMPs by AM-3 cells. Treatment with AM-3-conditioned medium induced inflammatory cytokine production of IL-6, MCP-1, and RANTES from MC3T3-E1 cells. The use of an IL-1 receptor antagonist suppressed the production of these inflammatory cytokines by MC3T3-E1 cells stimulated with AM-3-conditioned medium. The MC3T3-E1-conditioned medium triggered the expression of MMP-2 from AM-3 cells. Furthermore, we have shown that the proliferation and migration activity of AM-3 cells were accelerated by MC3T3-E1 conditioned media. In conclusion, these intercellular signalings between ameloblastoma cells and osteoblasts may play multiple roles in the pathogenesis of ameloblastoma. Ameloblastoma conditioned medium induced IL-6, MCP-1 and RANTES production from osteoblast cell in IL-1 dependent manner. Unidentified factors from osteoblast conditioned medium induced MMP-2 production and stimulate proliferation and cellular motility of ameloblastoma cells.

Abstract
BackgroundThe mortality rate of coronavirus disease 2019 (COVID-19) in patients with rheumatic and musculoskeletal disease (RMD) is as high as approximately 10% [1]. Therefore, vaccination promotion is a critical issue. However, there are few reports on the psychological aspects of patient vaccine acceptance.ObjectivesTo investigate the intention of patients with RMD to receive the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine and explore the psychological factors related to vaccine acceptance.MethodsWe conducted a questionnaire-based survey of 406 outpatients with RMD at Shiga General Hospital from July to October 2021. The questionnaire included the following sections: (1) vaccination status; (2) expectation of susceptibility to severe COVID-19; (3) expectation of vaccine efficacy; and (4) anxiety about the vaccine, which included concerns on I) the diminishing effect of the vaccine due to current treatment and II) the influence of vaccination on: i) primary disease status, ii) treatment, and iii) adverse reaction.ResultsThere were 305 vaccinated and 101 unvaccinated individuals. Unvaccinated individuals were classified into the acceptance group (n=60) and hesitancy group (n=41) according to their vaccination status (Figure 1).Figure 1.SARS-CoV-2 vaccination status (n=406)We compared the backgrounds and awareness of the patients on vaccination between the two groups. Univariate analysis did not show any difference in the backgrounds. The expectation of susceptibility to severe COVID-19 was similar in both groups. There were also no significant differences in the vaccine-related anxiety levels. However, the expectation of vaccine efficacy was higher in the acceptance group and significantly influenced vaccination intention as revealed by multivariate analyses (Table 1).Table 1.Awareness towards COVID-19 and SARS-CoV-2 vaccine associated with vaccination intentionAwareness towards COVID-19 and SARS-CoV-2 vaccineAcceptance(N=60)Hesitancy(N=41)UnivariateAnalysis§Multivariate Analysis||Median[IQR]Median[IQR]p-valuep-valueExpectation of susceptibility to severe COVID-19*2.0[1.0-3.0]2.0[1.5-2.5]0.84720.3440Expectation of vaccine efficacy†3.0[3.0-3.0]2.0[1.0-3.0]<0.0001¶<0.0001**Concerns about the diminishing effect of the vaccine due to current treatment‡2.0[1.0-3.0]3.0[2.0-3.0]0.04750.3600Concerns about the effect of vaccination on treatment‡3.0[1.0-3.0]3.0[2.0-4.0]0.01280.6232Concern about the effect of vaccination on primary disease status‡3.0[1.0-3.0]3.0[2.0-3.0]0.05760.7134Concern about the effect of vaccination on adverse reaction‡3.0[3.0-3.0]3.0[3.0-4.0]0.00930.8335*0: Less likely to become severe~3: Very likely to become severe, †0: Not expected at all~4: Highly expected, ‡0: Not concerned at all ~4:Very concerned§Pearson’s chi-square test or Wilcoxon test, ||Nominal logistic regression analysis, ¶ p<0.008 (after Bonferroni correction), ** p<0.05.ConclusionThe perception of vaccine efficacy is strongly correlated with vaccine acceptance.

Abstract
BACKGROUND AND AIMS Immune checkpoint inhibitors (ICIs) are used to treat several cancers, but they sometimes induce immune-related adverse events (irAEs). Patients with irAEs often have improved antitumor responses, but discontinuation of ICIs after irAEs is considered necessary. Resuming the use of ICIs after irAEs is preferable, but few studies have investigated the safety of ICI resumption after irAEs. Therefore, we evaluated the factors associated with the recurrence of irAEs after ICI resumption to investigate the safety of this approach. METHODS In this observational study, we enrolled patients treated with ICIs from September 2014 to March 2020 at our institution. Patient characteristics, ICIs, grades of irAEs, ICI discontinuation or resumption rates, and recurrence rates of irAEs after ICI therapy were analysed. RESULTS Two-hundred eighty-seven patients were included in the present study, and 76 patients experienced grade 2 or higher irAEs. Forty-two patients underwent ICI resumption after recovering from irAEs, and 13 of them had a recurrence of irAEs. Among those 13 patients, six had a recurrence of the same irAE, and seven experienced other irAEs. Ten of the 13 patients had grade ≥2 irAEs, and none had fatal irAEs. In the grade 2 or higher irAE group, more patients had irAEs associated with multiple organs and of initial grade ≥2 than those in the grade 1 and no recurrent irAEs group. CONCLUSIONS Patients with initial multisystemic irAEs and irAEs of grade ≥2 were more likely to experience relapse or develop new grade ≥2 irAEs after ICI resumption.

Abstract
Bone homeostasis is regulated by bone morphogenic proteins (BMPs), among which BMP9 is one of the most osteogenic. Here, we have found that BMP9 rapidly increases the protein expression of hypoxia-inducible factor-1α (HIF-1α) in osteoblasts under normoxic conditions more efficiently than BMP2 or BMP4. A combination of BMP9 and hypoxia further increased HIF-1α protein expression. HIF-1α protein induction by BMP9 is not accompanied by messenger RNA (mRNA) increase and is inhibited by the activation of prolyl hydroxylase domain (PHD)-containing protein, indicating that BMP9 induces HIF-1α protein expression by inhibiting PHD-mediated protein degradation. BMP9-induced HIF-1α protein increase was abrogated by inhibitors of phosphoinositide 3-kinase (PI3K) and protein kinase B (AKT) kinase, indicating that it is mediated by PI3K-AKT signaling pathway. BMP9 increased mRNA expression of pyruvate dehydrogenase kinase 1 (PDK1), a glycolytic enzyme, and vascular endothelial growth factor-A (VEGF-A), an angiogenic factor, in osteoblasts. Notably, BMP9-induced mRNA expression of PDK1, but not that of VEGF-A, was significantly inhibited by small interference RNA-mediated knockdown of Hif-1α. BMP9-induced matrix mineralization and osteogenic marker gene expressions were significantly inhibited by chemical inhibition and gene knockdown of either Hif-1α or Pdk-1, respectively. Since increased glycolysis is an essential feature of differentiated osteoblasts, our findings indicate that HIF-1α expression is important in BMP9-mediated osteoblast differentiation through the induction of PDK1.

Abstract
Staphylococcus epidermidis is a commensal bacterium in humans. To persist in the bacterial flora of the host, some bacteria produce antibacterial factors such as the antimicrobial peptides known as bacteriocins. In this study, we tried to isolate bacteriocin-producing S. epidermidis strains. Among 150 S. epidermidis isolates from the oral cavities of 287 volunteers, we detected two bacteriocin-producing strains, KSE56 and KSE650. Complete genome sequences of the two strains confirmed that they carried the epidermin-harboring plasmid pEpi56 and the nukacin IVK45-like-harboring plasmid pNuk650. The amino acid sequence of epidermin from KSE56 was identical to the previously reported sequence, but the epidermin synthesis-related genes were partially different. The prepeptide amino acid sequences of nukacin KSE650 and nukacin IVK45 showed one mismatch, but both mature peptides were entirely similar. pNuk650 was larger and had an additional seven ORFs compared to pIVK45. We then investigated the antibacterial activity of the two strains against several skin and oral bacteria and found their different activity patterns. In conclusion, we report the complete sequences of 2 plasmids coding for bacteriocins from S. epidermidis, which were partially different from those previously reported. Furthermore, this is the first report to show the complete sequence of an epidermin-carrying plasmid, pEpi56.

Abstract
Simple Summary Mucoepidermoid carcinoma (MEC) is the most common malignancy of all salivary neoplasms, and no effective treatment strategy for MEC has been established other than resection. In this study, we showed that Purkinje cell protein (PCP) 4/peptide (PEP) 19 and human epidermal growth factor receptor 2 (HER2) are predicted to play important roles in the pathogenesis and progression of MEC. The detection of PCP4/PEP19 and HER2 may be useful for providing more effective treatments against MEC. Abstract Mucoepidermoid carcinoma (MEC) is one of the most common malignant salivary gland carcinomas, but no effective treatment strategy has been established other than surgical resection. Purkinje cell protein (PCP) 4/peptide (PEP) 19 is a calmodulin-binding antiapoptotic peptide that is expressed and inhibits apoptosis in human breast cancer cells. Human epidermal growth factor receptor 2 (HER2) is an epidermal growth factor that has been implicated in the pathogenesis of many carcinomas, particularly breast and gastric carcinomas. In the present study, we performed immunohistochemical analyses of samples from 73 patients who underwent surgical resection for MEC of the salivary gland using antibodies against PCP4/PEP19 and HER2. PCP4/PEP19 expression was related to better prognosis, while HER2 expression was associated with worse prognosis. Patients that were PCP4/PEP19-positive and HER2-negative showed similar outcomes to PCP4/PEP19 and HER2 alone. Therefore, PCP4/PEP19 and HER2 are predicted to play important roles in the pathogenesis and progression of MEC.

Abstract
The aim of this retrospective cohort study was to compare the recurrence rate and speech outcomes between two techniques for palatal fistula closure of cleft palate (CP). Patients with CP who underwent secondary palatal fistula closure using the single hinge-flap method with double-breasted mattress suture (hinge-flap group) and those who were treated with the conventional sliding palatal flap method (sliding-flap group) were retrospectively evaluated for demographic and perioperative variables. Recurrence rate of palatal fistula, perceptual speech outcomes, and nasalance scores were further reviewed in patients who met the inclusion criteria. A total of 31 patients, 21 in the hinge-flap group and 10 in the sliding-flap group, were included in this study. The fistula recurrence rate in the hinge-flap group (0%) was significantly lower than that in the sliding-flap group (30.0%) (P = 0.027). In the speech assessment, hypernasality and nasalance scores decreased post-operatively in both groups and significance was observed in the hinge-flap group (P = 0.013, P < 0.001, respectively). Articulation disorders were significantly improved in the hinge-flap group (P = 0.001). Within the limitations of the study it seems that the single hinge-flap method with double-breasted mattress suture should be preferred whenever appropriate.

Abstract
BACKGROUND Currently, patients with dysphagia are receiving dietary management that deviates from their original swallowing function. OBJECTIVE To evaluate the clinical significance of fibreoptic endoscopic evaluation of swallowing (FEES) and dietary intervention (DI) by multi-professional collaboration during visit care for determining the actual oral intake status in patients with dysphagia. METHODS Five hundred and eighteen patients with dysphagia underwent FEES, focusing on the penetration-aspiration scale, and DI. Oral intake status was categorised using the functional oral intake scale (FOIS). FOIS scores at the first visit, after FEES, and at the reassessment were compared. RESULTS At the first visit, 34.7% of the patients had an FOIS score of level 1 (no oral intake) and 65.3% had a score of level 2 or higher (capable of oral intake). Following FEES, 7.1% of patients had an FOIS score of level 1, and 44.4% had a score of level 2 with resumption of oral intake. At the reassessment, 489 patients (94.4%) were capable of oral ingestion (FOIS level 2 or higher). There were significant differences between the distributions of FOIS scores at the first visit and following FEES (P < .01) and between those at the first visit and at the reassessment (P < .01). Regarding tube feeding, 17 (5.9%) of 289 patients, who had received tube feeding at the first visit, were completely capable of oral intake following FEES and at the reassessment. CONCLUSION Appropriate evaluation of swallowing function using FEES and DI helps to understand the definite swallowing function in patients with dysphagia.

Abstract
During the deposition of a metallic material on a substrate, a nanocluster-array structure with an extremely narrow gap is formed transiently at the transition between isolated clusters and the continuous film. It is known that the nanocluster array shows a unique electrical property different from that of isolated clusters and the continuous film. The electrical property of the nanocluster array changes significantly depending on its morphology, and precise control of the deposition time is indispensable to obtain a desired electrical property. However, the detection of the transition is not straightforward. To overcome this problem, we develop the multi-mode resistive spectroscopy. It evaluates the morphological change during deposition using resonant vibrations of a piezoelectric material and enables the fabrication of nanocluster arrays with a slightly different morphology. Palladium nanocluster arrays with different morphologies are fabricated using this method, and the availability of the multi-mode resistive spectroscopy is demonstrated by evaluating their electrical response to hydrogen gas.

Abstract
Ameloblastoma is benign odontogenic tumours that mainly occur in the jawbone. This tumour induces aggressive invasion into the surrounding bone and has a high recurrence rate after surgery. Therefore, mandibular resection is performed in many patients with this tumour, causing aesthetic and functional problems. It is necessary to develop a novel treatment strategy for ameloblastoma, but there are currently no innovative treatments. Although our understanding of the molecular biological mechanisms of ameloblastoma is still insufficient, there have been many recent reports of new molecular biological findings on ameloblastoma. Therefore, bioactive factors that have potential for novel therapeutic methods, such as molecular targeted therapy, have been discovered in ameloblastoma. In this review, we summarize the molecular biological findings of ameloblastoma reported over several decades, focusing on factors involved in invasion into surrounding tissues and disease-specific gene mutations. We also mention the effect of the interaction between tumour cells and stromal components in ameloblastoma on tumour development.

Abstract
Bone morphogenetic protein (BMP) 9 is one of the most osteogenic BMPs, but its mechanism of action has not been fully elucidated. Hes1, a transcriptional regulator with a basic helix-loop-helix domain, is a well-known effector of Notch signaling. Here, we find that BMP9 induces periodic increases of Hes1 mRNA and protein expression in osteoblasts, presumably through an autocrine negative feedback mechanism. BMP9-mediated Hes1 induction is significantly inhibited by an ALK inhibitor and overexpression of Smad7, an inhibitory Smad. Luciferase and ChIP assays revealed that two Smad-binding sites in the 5' upstream region of the mouse Hes1 gene are essential for transcriptional activation by BMP9. Thus, our data indicate that BMP9 induces Hes1 expression in osteoblasts via the Smad signaling pathway.

Abstract
Abstract
Introduction
Intraplaque hemorrhage (IPH) is known to play an important role in plaque vulnerability in coronary artery. However, the biological reaction in IPH and clinical features of patients with IPH remain unknown, since most histological studies of IPH in coronary artery were performed on autopsy cases. Directional coronary atherectomy (DCA) enables the direct pathological evaluation of collected tissue from “living” patients.
Purpose
We aimed to clarify the clinical presentations and histopathologic features of IPH using specimens obtained by DCA.
Method
This multicentral prospective observational study included consecutive patients who underwent percutaneous coronary intervention for de novo lesions using DCA from June 2015 to February 2018. Histopathological sections that were collected from coronary plaques by DCA were evaluated and classified by the presence of IPH. IPH in DCA specimens was defined as clusters of hemosiderin (Figure A, arrows), erythrocytes (Figure B, arrow heads) and fibrin (Figure C, arrows) within the coronary plaque. A total of 154 de novo lesions from 154 patients were ultimately analyzed, and were divided into IPH group (n=37) and non-IPH group (n=117).
Result
Clinical profiles of patients in the two groups were comparable, except that unstable angina rather than chronic coronary syndrome was significantly more prevalent in the IPH group (32.4% vs. 16.2%, P=0.04). Histopathological analysis showed a significantly higher incidence of cellular-rich plaque (46.0% vs. 25.6%, P=0.02) and spindle-shaped cells (18.9% vs. 6.0%, P=0.02), which indicate active cell proliferations, in the IPH group. The prevalence of necrotic core was also higher in IPH group compared to non-IPH group (48.7% vs. 13.7%, P<0.01).
Conclusion
Pathohistological analysis revealed that coronary plaques with IPH had an active cell proliferation, and patients with IPH likely to had clinical presentations of unstable angina.

Abstract
To compare three-dimensional (3D) nasal forms after definitive correction of unilateral cleft lip (UCL)-nose using an extended spreader cartilage graft with/without a cross-lap joint cartilage graft technique. Twenty-four patients with UCL who underwent definitive nose correction using an extended spreader cartilage graft with a cross-lap joint technique (CLJ group) and fifteen patients with UCL who underwent nose correction without a cross-lap joint technique (non-CLJ group) were enrolled in this study. Pre- and postoperative 3D nasal forms were compared between the two groups. The CLJ group demonstrated more successful recovery of the nasal tip and anterior nasal ridge in the center of the face (P < 0.01), and the higher nasal tip was maintained for more than 1 year (P = 0.008). The differences in the cephalo-caudal heights of the nasal alar groove and curvatures of the alar groove arch were successfully improved in both CLJ and non-CLJ groups. The nasal angles on lateral profiles did not change in either group. An extended spreader cartilage graft with a cross-lap joint technique facilitates satisfactory recovery of the nasal tip in the center of the face and a higher nasal tip, avoiding over-projection in the definitive correction of UCL-nose.

Abstract
Objective Ameloblastoma is a representative odontogenic tumor comprising several characteristic invasive forms, and its pathophysiology has not been sufficiently elucidated. A stable animal experimental model using immortalized cell lines is crucial to explain the factors causing differences among the subtypes of ameloblastoma, but this model has not yet been disclosed. In this study, a novel animal experimental model has been established, using immortalized human ameloblastoma-derived cell lines. Methodology Ameloblastoma cells suspended in Matrigel were subcutaneously transplanted into the heads of immunodeficient mice. Two immortalized human ameloblastoma cell lines were used: AM-1 cells derived from the plexiform type and AM-3 cells derived from the follicular type. The tissues were evaluated histologically 30, 60, and 90 days after transplantation. Results Tumor masses formed in all transplanted mice. In addition, the tumors formed in each group transplanted with different ameloblastoma cells were histologically distinct: the tumors in the group transplanted with AM-1 cells were similar to the plexiform type, and those in the group transplanted with AM-3-cells were similar to the follicular type. Conclusions A novel, stable animal experimental model of ameloblastoma was established using two cell lines derived from different subtypes of the tumor. This model can help clarify its pathophysiology and hasten the development of new ameloblastoma treatment strategies.

Abstract
Background: Betel quid chewing is more common among the older generation in rural areas of Malaysia. Oral cancer in Asia has been associated with the habit of chewing betel quid and areca nut. Objective: This study aims to investigate the cytotoxic effects of betel quid and areca nut extracts on the fibroblast (L929), mouth-ordinary-epithelium 1 (MOE1) and oral squamous cell carcinoma (HSC-2) cell lines. Methods: L929, MOE1 and HSC-2 cells were treated with 0.1, 0.2 and 0.4 g/ml of betel quid and areca nut extracts for 24, 48 and 72 h. MTT assay was performed to assess the cell viability. Results: Both extracts, regardless of concentration, significantly reduced the cell viability of L929 compared with the control (P<0.05). Cell viability of MOE1 was significantly enhanced by all betel quid concentrations compared with the control (P<0.05). By contrast, 0.4 g/ml of areca nut extract significantly reduced the cell viability of MOE1 at 48 and 72 h of incubation. Cell viability of HSC-2 was significantly lowered by all areca nut extracts, but 0.4 g/ml of betel quid significantly increased the cell viability of HSC-2 (P<0.05). Conclusion: Areca nut extract is cytotoxic to L929 and HSC-2, whereas the lower concentrations of areca nut extract significantly increased the cell viability of MOE1 compared to the higher concentration and control group. Although betel quid extract is cytotoxic to L929, the same effect is not observed in MOE1 and HSC-2 cell lines. Further investigations are needed to clarify the mechanism of action.

Abstract
Octacalcium phosphate and its collagen composite have been recognized as bone
substitute materials possessing osteoconductivity and biodegradation properties.
We evaluated the effectiveness of octacalcium phosphate and its collagen
composite used for bone augmentation in major oral and maxillofacial surgeries
in a clinical trial. Octacalcium phosphate and its collagen composite were used
in cases of sinus floor elevation in 1- and 2-stage, socket preservation, cyst,
and alveolar cleft procedures. A total of 60 patients were evaluated for
effectiveness after the implantation of octacalcium phosphate and its collagen
composite. Although sinus floor elevation in 1-stage, cyst, and alveolar cleft
cases met the criteria for the judgment of success, sinus floor elevation in
2-stage and socket preservation groups did not meet the criteria in the initial
evaluation. However, an additional evaluation for reconfirmation revealed the
effectiveness of octacalcium phosphate and its collagen composite in those
groups, and all evaluation results ultimately indicated the success of this
clinical trial. Therefore, this clinical trial suggested that application of
octacalcium phosphate and its collagen composite for oral and maxillofacial
surgery was safe and effective and that octacalcium phosphate and its collagen
composite could be a bone substitute candidate instead of autologous bone.

Abstract
OBJECTIVE To update and expand upon prior Osteoarthritis Research Society International (OARSI) guidelines by developing patient-focused treatment recommendations for individuals with Knee, Hip, and Polyarticular osteoarthritis (OA) that are derived from expert consensus and based on objective review of high-quality meta-analytic data. METHODS We sought evidence for 60 unique interventions. A systematic search of all relevant databases was conducted from inception through July 2018. After abstract and full-text screening by two independent reviewers, eligible studies were matched to PICO questions. Data were extracted and meta-analyses were conducted using RevMan software. Grading of Recommendations Assessment, Development, and Evaluation (GRADE) Evidence Profiles were compiled using the GRADEpro web application. Voting for Core Treatments took place first. Four subsequent voting sessions took place via anonymous online survey, during which Panel members were tasked with voting to produce recommendations for all joint locations and comorbidity classes. We designated non-Core treatments to Level 1A, 1B, 2, 3, 4A, 4B, or 5, based on the percentage of votes in favor, in addition to the strength of the recommendation. RESULTS Core Treatments for Knee OA included arthritis education and structured land-based exercise programs with or without dietary weight management. Core Treatments for Hip and Polyarticular OA included arthritis education and structured land-based exercise programs. Topical non-steroidal anti-inflammatory drugs (NSAIDs) were strongly recommended for individuals with Knee OA (Level 1A). For individuals with gastrointestinal comorbidities, COX-2 inhibitors were Level 1B and NSAIDs with proton pump inhibitors Level 2. For individuals with cardiovascular comorbidities or frailty, use of any oral NSAID was not recommended. Intra-articular (IA) corticosteroids, IA hyaluronic acid, and aquatic exercise were Level 1B/Level 2 treatments for Knee OA, dependent upon comorbidity status, but were not recommended for individuals with Hip or Polyarticular OA. The use of Acetaminophen/Paracetamol (APAP) was conditionally not recommended (Level 4A and 4B), and the use of oral and transdermal opioids was strongly not recommended (Level 5). A treatment algorithm was constructed in order to guide clinical decision-making for a variety of patient profiles, using recommended treatments as input for each decision node. CONCLUSION These guidelines offer comprehensive and patient-centered treatment profiles for individuals with Knee, Hip, and Polyarticular OA. The treatment algorithm will facilitate individualized treatment decisions regarding the management of OA.

Abstract
PURPOSE Complications during local anesthesia include increased blood pressure and vasovagal reflex, which are caused by changes in the autonomic nervous system. The commonly used local anesthetic preparations are lidocaine to which the vasoconstrictor epinephrine is added (lidocaine-epinephrine) and prilocaine to which the vasoconstrictor felypressin is added (prilocaine-felypressin); however, their effects during dental treatment are unclear. We examined the effects of these 2 different local anesthetic preparations on the autonomic nervous system and circulation during extraction of the impacted mandibular third molar. MATERIALS AND METHODS In this randomized controlled trial, 40 female patients scheduled for extraction of an impacted mandibular third molar were randomized to the lidocaine-epinephrine group or prilocaine-felypressin group. Heart rate variability, heart rate, and systolic blood pressure were recorded during the experiment. Descriptive and bivariate statistics were computed, and the P value was set at .05. RESULTS The low frequency-high frequency ratio was significantly increased in the prilocaine-felypressin group during extraction compared with that in the lidocaine-epinephrine group (P < .05). In the lidocaine-epinephrine group, a significant decrease in the high-frequency component was observed during bone removal and extraction compared with that at rest (P < .05). In both groups, a significant increase in systolic blood pressure was observed during local anesthesia, incision and reflection of the flap, bone removal, separation of the tooth crown, extraction, and suturing compared with that at rest (P < .01). CONCLUSIONS This study is the first to investigate the differences in the influence of 2 different local anesthetic preparations on the autonomic nervous system during extraction of the mandibular third molar. Changes in circulatory dynamics during tooth extraction with the 2 different local anesthetic preparations were the result of a decrease in parasympathetic nervous activity with lidocaine-epinephrine and an increase in sympathetic nervous activity with prilocaine-felypressin.

Abstract
Nanopore-based diagnostic systems are a promising tool for counting viruses in a specimen one by one. However, despite intensive R&D efforts, it remains difficult to recognize virus subtypes by nanopore devices. We thus propose a novel diagnostic system that combines a specialized virus recognition procedure with a nanopore detection procedure. This recognition procedure consists of three steps: 1) capture target viruses using specific probes for recognition; 2) release captured targets; and 3) detect released targets by nanopore. Proof-of-concept tests are conducted using avidin-modified fluorescent particles (as a model for viruses) and biotin-modified alkane thiol (as a model for probes). The avidin-modified particles are confirmed to be captured on electrode by biotin-modified probes and then, the particles are electrochemically released from the electrode. Consequently, the released particles are successfully detected by nanopore devices. Furthermore, the concept is also proved by using human influenza viruses (H1N1, A/PR/8/34) and sugar chain (6'-sialyllactose)-modified probes. This suggests that our concept is applicable to various infectious diseases by changing probes (ligands).

Abstract
Abstract
Introduction
The Global Registry of Acute Coronary Events (GRACE) score is said to be a superior predictor of mortality in acute myocardial infarction (AMI) patients, and same applies to biochemical parameters as N-terminal pro-B-type natriuretic peptide (N-BNP), Troponin-T (TnT) and high-sensitivity C- reactive protein (hs-CRP) levels.
Purpose
We validated that whether each or combination of biochemical parameters are comparable to GRACE score or not for mortality prediction in AMI patients.
Method
We investigated about clinical background including The GRACE score, above parameters and in-hospital mortality in 754 AMI patients (mean age 66±13y/o, 609 ST-elevated AMI cases) received emergency percutaneous coronary intervention (PCI) successfully during 8 years in a single center retrospectively. Combination of biochemical parameters are derived from N-BNP, TnT and hs-CRP by logistic regression analyses. We compared The GRACE score with each or combination of biochemical parameters between survival (SG) and non-survival group (nSG) on receiver operating characteristic (ROC) analysis.
Result
In-hospital mortality was 6.8%. The GRACE score (106±33 versus 161±32; p<0.005) and N-BNP level (2458±7058 versus 8880±11331pg/ml; p<0.005) were significantly lower in SG than nSG. Area under the ROC curve about in-hospital mortality of The GRACE score were higher (0.868) than N-BNP (0.787; p=0.007), TnT (0.613; p<0.005), hs-CRP levels (0.614; p<0.005) and multi-biomarker combination (0.742; p=0.016) as Figure 1.
Area under the curve of the composite with the GRACE score and multi-biomarker is not increased compared with the GRACE score alone (0.868 versus 0.865; p=n.s.).
Figure 1
Conclusion
The GRACE score is a superior predictor about in-hospital mortality than each or combination of biochemical parameters in AMI patients. Multi-biomarker combination dose not refine the accuracy of the GRACE score.

Abstract
Tobacco smoking is considered as one of the major risk factors for development of oral cancer. In vitro studies indicate that cigarette smoke initiates transformation of epithelial cells toward development of oral cancer through altering mitochondrial metabolic pathways. However the present in vitro models need to be improved to correlate these molecular changes with epithelial transformations. In present study, we investigated the association of mitochondrial metabolic events with oral cancer progression under cigarette smoke extract (CSE). In this regard, an in vitro model of oral keratinocyte cell line (MOE1A) was developed by exposing them with different concentrations of CSE. Alterations in cellular phenomena were confirmed by Fourier-transform infrared spectroscopy (FTIR) study, which indicated changes in important functional groups of CSE-induced oral cells. Enhanced reactive oxygen species (ROS) of exposed cells altered the mitochondrial metabolic activities in terms of increased mitochondrial mass and DNA content. Further, mitochondrial heme-metabolism was investigated and real-time PCR study showed altered expression of important genes like ALAS1, ABCB6, CPOX, FECH, HO-1. Both transcriptomic and proteomic studies showed up- and down-regulation of important biomarkers related to cellular cancer progression. Overall data suggest that CSE alters mitochondrial heme metabolic pathway and initiates cancer progression through modifying cellar biomarkers in oral epithelial cells.

Abstract
Objective: To examine the relationship between the method of anesthesia for alveolar bone graft surgery and postoperative nausea and vomiting (PONV) based on the difference in surgical timing and to assess factors related to the postoperative quality of life. Design: Retrospective observational study. Setting: Hospital. Participants: Patients with cleft lip and palate who underwent alveolar bone graft surgery under general anesthesia. The subjects were divided into two groups based on surgical timing: secondary bone graft (SBG) and late secondary bone graft (LSBG) groups. Main Outcome Measures: Relationship between time to recovery of feeding and the types of anesthesia, PONV, and postoperative pain period. Results: The mean patient age was 9.97 ± 1.33 years in the SBG group and 15.39 ± 0.31 years in the LSBG group. In the SBG group, patients who were administered fentanyl or remifentanil had significantly higher incidence of PONV than those who were not administered these drugs. In the SBG group, the time to recovery of feeding was significantly longer in patients experiencing PONV within 2 hours or that lasted for 24 hours than in those without PONV. In the LSBG group, there was no significant difference regarding any of the above factors. Conclusions: Our results suggest that the occurrence of PONV within 2 hours or lasting for 24 hours postoperatively in school-age children prolonged the time to recovery of feeding. This indicates that the time to recovery of feeding can be predicted based on the occurrence of PONV within the first 2 hours.

Abstract
People variably respond to global change in their beliefs, behaviors, and grief (associated with losses incurred). People that are less likely to believe in climate change, adopt pro-environmental behaviors, or report ecological grief are assumed to have different psycho-cultural orientations, and do not perceive changes in environmental condition or any impact upon themselves. We test these assumptions within the context of the Great Barrier Reef (GBR), a region currently experiencing significant climate change impacts in the form of coral reef bleaching and increasingly severe cyclones. We develop knowledge of environmental cultural services with the Environmental Schwartz Value Survey (ESVS) into four human value orientations that can explain individuals’ environmental beliefs and behaviors: biospheric (i.e., concern for environment), altruistic (i.e., concern for others, and intrinsic values), egoistic (i.e., concern for personal resources) and hedonic values (i.e., concern for pleasure, comfort, esthetic, and spirituality). Using face-to-face quantitative survey techniques, where 1,934 residents were asked to agree or disagree with a range of statements on a scale of 1–10, we investigate people’s (i) environmental values and value orientations, (ii) perceptions of environmental condition, and (iii) perceptions of impact on self. We show how they relate to the following climate change responses; (i) beliefs at a global and local scale, (ii) participation in pro-environmental behaviors, and (iii) levels of grief associated with ecological change, as measured by respective single survey questions. Results suggest that biospheric and altruistic values influenced all climate change responses. Egoistic values were only influential on grief responses. Perception of environmental change was important in influencing beliefs and grief, and perceptions of impact on self were only important in influencing beliefs. These results suggest that environmental managers could use people’s environmental value orientations to more effectively influence climate change responses toward environmental stewardship and sustainability. Communications that target or encourage altruism (through understanding and empathy), biospherism (through information on climate change impacts on the environment), and egoism (through emphasizing the benefits, health and wellbeing derived from a natural resource in good condition), could work.

Abstract
Helicobacter pylori (Hp) infection is related to the pathogenesis of chronic gastric disorders and extragastric diseases. Here, we examined the anorexigenic and anxiogenic effects of Hp vacuolating cytotoxin A (VacA) through activation of hypothalamic urocortin1 (Ucn1). VacA was detected in the hypothalamus after peripheral administration and increased Ucn1 mRNA expression and c-Fos-positive cells in the hypothalamus but not in the nucleus tractus solitarius. c-Fos and Ucn1-double positive cells were detected. CRF1 and CRF2 receptor antagonists suppressed VacA-induced anxiety and anorexia, respectively. VacA activated single paraventricular nucleus neurons and A7r5 cells; this activation was inhibited by phospholipase C (PLC) and protein kinase C (PKC) inhibitors. VacA causes anorexia and anxiety through the intracellular PLC-PKC pathway, migrates across the blood-brain barrier, and activates the Ucn1-CRF receptor axis.

Abstract
Basic dose quantities used in dose reconstruction are defined. The following dose reconstruction methods based on measurements performed for individual persons are reviewed: electron paramagnetic resonance (EPR) measurements with tooth enamel, analyses of dicentric chromosomes and chromosome translocations, counting of micronuclei in lymphocytes, somatic-mutation assays, and measurements of radionuclide activities in the human body. Methods based on measurements in environmental media include luminescence methods applied to minerals to determine absorbed doses in ceramics such as bricks or porcelain, accelerator mass spectrometry (AMS) to determine small quantities of man-made long-lived radionuclides, methods based on existing measurements of absorbed dose rates in air, and modelling based on radionuclide activities in the environment. The application of different methods of dose reconstruction to the same individuals is reviewed for the atomic-bomb survivors of Hiroshima and Nagasaki (dosimetry system DS86, EPR with teeth, chromosomal aberrations in lymphocytes, and somatic-mutation assays) and the workers of the Mayak Production Association (occupational film badge dosimetry, EPR with teeth, and fluorescence in situ hybridisation (FISH) with lymphocytes). Examples of reconstruction of absorbed doses in environmental media are Hiroshima and Nagaski (luminescence measurements, AMS and the DS86 system), the Nevada test site (measurements of 137Cs activity in the soil, thermoluminescence of bricks and gamma dose rate in air), and settlements contaminated by the Chernobyl accident (luminescence methods and modelling based on measured 137Cs activity in the ground). The report concludes with an overview the conditions under which the various methods of the dose reconstruction are best applied.

Abstract
OBJECTIVE There is debate on the reliability of the Americleft Yardstick (AY) global nasolabial appearance assessment method. The objective was to analyze the effect of the additional basal view (BV) feature on the reliability of the AY method for Japanese children with complete cleft lip and palate (CUCLP). DESIGN Blind retrospective analysis of clinical records on 43 patients (5- to 7-year-old) with nonsyndromic CUCLP who underwent primary lip repair from 2005 to 2011. MAIN OUTCOME MEASURE Color pictures published in AY and Rubin's studies were used as reference pictures. Patients' photographs were cropped and rated on a 5-point scale for the vermilion border (VB), nasolabial frontal (NLF), and nasolabial profile (NLP) according to AY with/without BV assessment by Rubin's methods. Rating was performed twice by 3 oral surgeons. Intra- and inter-rater reliabilities were analyzed using weighted κ, and correlations between BV and other features were analyzed. RESULTS Overall average assessment scores were 2.742 (0.573) with AY and 2.702 (0.489) with AY+BV methods (P = .728). Average intra-rater reliabilities were 0.605 and 0.611 and average inter-rater reliabilities were 0.525 and 0.48 with AY and AY+BV, respectively. Inter-rater reliability was the lowest for NLP. ρ scores between BV versus VB, NLF, and NLP were 0.025, 0.659, and 0.092, respectively. CONCLUSIONS Present study demonstrates moderate intra- and inter-rater reliabilities obtained with the AY assessment method for Japanese children with CUCLP. Nasolabial profile standard ambiguity may lead to the poor reliability of AY assessment. Addition of the BV feature does not improve overall reliability.

Abstract
Objective: To visualize and quantitatively analyze facial surface asymmetry following primary cleft lip repair in patients with unilateral cleft lip and palate (UCLP) and to compare this with noncleft controls. Design: Retrospective comparative study. Patients: Twenty-two patients with complete UCLP who underwent primary lip repair from 2009 to 2013 were enrolled in this study. The preserved 3-dimensional (3D) data of 23 healthy Japanese participants with the same age were used as controls. Interventions: All patients had received primary labioplasty in accordance with Cronin triangular flap method with orbicular oris muscle reconstruction. Main Outcome Measures: Shadow and zebra images established from moiré images, which were reconstructed from 3D facial data using stereophotogrammetry, were bisected and reversed by the symmetry axes (the middle line of the face). The discrepancies of the gravity and density between cleft and noncleft sides in 2 regions of interest, facial and lip areas, were then calculated and compared with those of healthy participants. Results: In the UCLP group, the mean discrepancies of gravity on shadow and zebra images were 1.76 ± 0.70 and 2.63 ± 1.72 pixels, respectively, in the facial area and 1.31 ± 0.36 and 3.83 ± 2.08 pixels, respectively, in the lip area. There was a significant difference in the mean discrepancies of gravity and density on zebra images in the lip area between the UCLP and control groups. Conclusions: Our image analysis of digital facial surface asymmetry in patients with UCLP provides visual and quantitative information, and it may contribute to improvements in muscle reconstruction on cleft lip repair.
