Abstract
BACKGROUND To compare the clinical outcomes of two treatment modalities, initial surgery and primary definitive radiotherapy (RT), in Taiwanese patients diagnosed with cT1-2N0M0 oral cavity squamous cell carcinoma (OCSCC). METHODS Between 2011 and 2019, we analyzed data for 13,542 cT1-2N0M0 patients who underwent initial surgery (n = 13,542) or definitive RT with a dosage of at least 6600 cGy (n = 145) for the treatment of OCSCC. To account for baseline differences, we employed propensity score (PS) matching, resulting in two well-balanced study groups (initial surgery, n = 580; definitive RT, n = 145). RESULTS Before PS matching, the 5-year disease-specific survival (DSS) rates were 88% for the surgery group and 58% for the RT group. After PS matching, the 5-year DSS rates of the two groups were 86% and 58%, respectively. Similarly, the 5-year overall survival (OS) rates before PS matching were 80% for the surgery group and 36% for the RT group, whereas after PS matching, they were 73% and 36%, respectively. All these differences were statistically significant (p < 0.0001). A multivariable analysis identified treatment with RT, older age, stage II tumors, and a higher burden of comorbidities as independent risk factors for both DSS and OS. We also examined the 5-year outcomes for various subgroups (margin ≥5 mm, margin <5 mm, positive margins, RT combined with chemotherapy, and RT alone) as follows: DSS, 89%/88%/79%/63%/51%, respectively, p < 0.0001; OS, 82%/79%/68%/39%/32%, respectively, p < 0.0001. CONCLUSIONS In Taiwanese patients with cT1-2N0M0 OCSCC, a remarkably low proportion (1.1%) completed definitive RT. A significant survival disparity of 30% was observed between patients who underwent initial surgery and those who received definitive RT. Interestingly, even patients from the surgical group with positive surgical margins exhibited a significantly superior survival compared to those in the definitive RT group.

Abstract
BACKGROUND While several studies have indicated that a margin status of < 1 mm should be classified as a positive margin in oral cavity squamous cell carcinoma (OCSCC), there is a lack of extensive cohort studies comparing the clinical outcomes between patients with positive margins and margins < 1 mm. METHODS Between 2011 and 2020, we identified 18,416 Taiwanese OCSCC patients who underwent tumor resection and neck dissection. Of these, 311 had margins < 1 mm and 1013 had positive margins. To compare patients with margins < 1 mm and those with positive margins, a propensity score (PS)-matched analysis (n = 253 in each group) was conducted. RESULTS The group with margins < 1 mm displayed a notably higher prevalence of several variables: 1) tongue subsite, 2) younger age, 3) smaller depth of invasion), 4) early tumor stage, and 5) treatment with surgery alone. Patients with margins < 1 mm demonstrated significantly better disease-specific survival (DSS) and overall survival (OS) rates compared to those with positive margins (74 % versus 53 %, 65 % versus 43 %, both p < 0.0001). Multivariable analysis further confirmed that positive margins were an independent predictor of worse 5-year DSS (hazard ratio [HR] = 1.38, p = 0.0103) and OS (HR = 1.28, p = 0.0222). In the PS-matched cohort, the 5-year outcomes for patients with margins < 1 mm compared to positive margins were as follows: DSS, 71 % versus 59 %, respectively (p = 0.0127) and OS, 60 % versus 48 %, respectively (p = 0.0398). CONCLUSIONS OCSCC patients with a margin status < 1 mm exhibited distinct clinicopathological characteristics and a more favorable prognosis compared to those with positive resection margins.

Abstract
The objective of this study was to evaluate the effects of weaning age and pace on blood metabolites, cortisol concentration, and mRNA abundance of inflammation-related genes in Holstein dairy calves. Seventy-one day-old calves [38.8 ± 4.4 kg, body weight (BW) ± sd] blocked by gender and birth BW, were randomly assigned to a 2 × 2 factorial arrangement of treatments. The first factor was weaning age [6 weeks (early) vs. Eight weeks (late)], the second factor was weaning pace [abrupt (4 step-down over 3 d, the initial milk replacer was 7.6 L, which was reduced 1.9 L in each step-down) vs. gradual (7 step-down over 14 d, the initial milk replacer was 7.6 L, which was reduced 1.09 L in each step-down)], generating early-abrupt (EA), early-gradual (EG), late-abrupt (LA), and late-gradual (LG) treatments. All treatments had 10 female and 8 male calves, except EA that had 1 fewer male calf. Milk replacer (MR; 24% CP, 17% fat) was bottle-fed, up to 1,200 g/d, twice daily (0600h and 1800h). EA and EG calves received 46.2 kg MR while LA and LG calves received a total of 63 kg MR. The study had 2 cohorts (2020, n = 40; 2021, n = 31), and each cohort included all treatments. Blood was collected from the jugular vein at 0900h on d 3 and d 7 of age, a day before starting and a day after weaning completion; male calves were humanely killed a day post-weaning. Rumen, jejunum, large intestine, liver, omental adipose and perirenal adipose tissues were sampled to determine the mRNA abundance of inflammation-related genes. Weaning pace, age, and pace × age, birth BW, and sex were included as fixed and cohort was included as random effects in the model. Blood metabolites and cortisol were analyzed as repeated measure, and sampling day, pace × sampling day, and age × sampling day were also included as additional fixed effects. Significance were noted at P ≤ 0.05 and tendencies when 0.05

Abstract
BACKGROUND Fibula Jaw-in-a-Day (JIAD) is considered the most advanced approach for segmental mandibular defect reconstruction and dental rehabilitation. However, it has limitations and challenges for further pursuit. We propose Fibula Jaw-during-Admission (JDA) as a solution. MATERIALS AND METHODS From 2019 to 2021, six patients received fibula "Jaw-during-Admission." Segmental mandibulectomy, fibula transfer, and immediate dental implantation were performed simultaneously during a single surgery. Intraoral scans were used to fabricate temporary light occlusion contact dental prostheses while on the ward prior to discharge during the first and second week post operation. The prostheses were installed before discharge and changed to permanent ones with normal occlusal contact in the clinic at about six months after X-ray confirmation of bone healing. RESULTS All six surgeries succeeded. Four patients received palatal muco-periosteal graft after debridement of peri-implant overgrown granulation tissue. Follow-up ranged from 12 to 34 months (average 21.2 months) and revealed good function and appearance in all patients. CONCLUSION Fibula JDA is superior to the Fibula JIAD approach for simultaneous mandibular reconstruction with fibula and dental rehabilitation. There is no need for postoperative intermaxillary fixation. The surgery can be performed more reliably with less stress. It provides an additional opportunity for dental rehabilitation if initial dental prosthesis installation during JIAD fails. Postreconstruction intraoral scans provide greater precision and more flexibility in milling dental prosthesis which are mapped to the reconstructed mandible during the postoperative period.

Abstract
OBJECTIVES According to the NCCN guidelines, there is weak evidence to support the use of elective neck dissection (END) in early-stage oral cavity squamous cell carcinoma (OCSCC). We sought to examine the indications for END in patients with cT1N0M0 OCSCC defined according to the AJCC Staging Manual, Eight Edition. METHODS Of the 3886 patients diagnosed with cT1N0M0 included in the study, 2065 underwent END and 1821 neck observation. RESULTS The 5-year outcomes for patients who received END versus neck observation before and after propensity score matching (n = 1406 each) were as follows: neck control, 96 %/90 % (before matching), p < 0.0001; 96 %/90 % (after matching), p < 0.0001; disease-specific survival (DSS), 93 %/92 % (before matching), p = 0.0227; 93 %/92 % (after matching), p = 0.1436. Multivariable analyses revealed that neck observation, depth of invasion (DOI) > 2.5 mm, and poor differentiation were independent risk factors for 5-year outcomes. Upon the application of a scoring system ranging from 0 (no risk factor) to 3 (presence of the three risk factors), the following 5-year rates were observed: neck control, 98 %/95 %/84 %/85 %; DSS, 96 %/93 %/88 %/85 %; and overall survival, 90 %/86 %/79 %/59 %, respectively (all p < 0.0001). The survival outcomes of patients with scores of 0 and 1 were similar. The occult metastasis rates in the entire study cohort, DOI > 2.5 mm, and poor differentiation were 6.8 %/9.2 %/17.1 %, respectively. CONCLUSION Because all patients who received neck observation had a score of 1 or higher, END should be performed when a DOI > 2.5 mm or poorly differentiated tumors are present. Under these circumstances, 48.6 % (1888/3886) of cT1N0M0 patients may avoid END without compromising oncological outcomes.

Abstract
BACKGROUND The prognostic significance of the relapse interval in patients with resected oral cavity squamous cell carcinoma (OCSCC) is a matter of ongoing debate. In this large-scale, registry-based, nationwide study, we examined whether the time interval between surgery and the first disease relapse may affect survival outcomes in Taiwanese patients with OCSCC. METHODS Data made available by the Taiwan Health Promotion Administration as of 2004 were obtained. The study cohort consisted of patients who were included in the registry between 2011 and 2017. Disease staging was performed according to the American Joint Committee on Cancer (AJCC) Staging Manual, Eight Edition. We retrospectively reviewed the clinical records of 13,789 patients with OCSCC who received surgical treatment. A total of 2327 (16.9%) patients experienced a first disease relapse. The optimal cutoff value for the relapse interval was 330 days when both 5-year disease-specific survival (DSS) and overall survival (OS) (≤ 330/>330 days, n = 1630/697) were taken into account. In addition, we undertook a propensity score (PS)-matched analysis of patients (n = 654 each) with early (≤ 330 days) versus late (> 330 days) relapse. RESULTS The median follow-up time in the entire study cohort was 702 days (433 and 2001 days in the early and late relapse groups, respectively). Compared with patients who experienced late relapse, those with early relapse showed a higher prevalence of the following adverse prognostic factors: pT4, pN3, pStage IV, poor differentiation, depth of invasion ≥ 10 mm, and extra-nodal extension. Multivariable analysis revealed that early relapse was an independent adverse prognostic factor for both 5-year DSS and OS (average hazard ratios [AHRs]: 3.24 and 3.91, respectively). In the PS-matched cohort, patients who experienced early relapse showed less favorable 5-year DSS: 58% versus 30%, p < 0.0001 (AHR: 3.10 [2.69 - 3.57]) and OS: 49% versus 22%, p < 0.0001 (AHR: 3.32 [2.89 - 3.81]). CONCLUSION After adjustment for potential confounders and PS matching, early relapse was an adverse prognostic factor for survival outcomes in patients with OCSCC. Our findings may have significant implications for risk stratification.

Abstract
BackgroundIn the treatment of oral cavity squamous cell carcinoma (OCSCC), surgical quality measures which are expected to affect outcomes, including the achievement of a clear margin, are surgeon-dependent but might not be invariably associated with hospital volume. Our objective was to explore surgical margin variations and survival differences of OCSCC between two highest-volume hospitals in Taiwan.Materials and methodsA total of 2009 and 1019 patients with OCSCC who were treated at the two highest-volume Taiwanese hospitals (termed Hospital 1 and Hospital 2, respectively) were included. We examined how a pathological margin <5 mm impacted patient outcomes before and after propensity score (PS) matching.ResultsThe prevalence of margins <5 mm was markedly lower in Hospital 1 than in Hospital 2 (34.5%/65.2%, p<0.0001). Compared with Hospital 2, tumor severity was higher in Hospital 1. On univariable analysis, being treated in Hospital 2 (versus Hospital 1; hazard ratio [HR] for 5-year disease-specific survival [DSS] = 1.34, p=0.0002; HR for 5-year overall survival [OS] = 1.17, p=0.0271) and margins <5 mm (versus ≥5 mm; HR for 5-year DSS = 1.63, p<0.0001; HR for 5-year OS = 1.48, p<0.0001) were identified as adverse factors. The associations of treatment in Hospital 2 and margins <5 mm with less favorable outcomes remained significant after adjustment for potential confounders in multivariable analyses, as well as in the PS-matched cohort. The 5-year survival differences between patients operated in Hospital 1 and Hospital 2 were even more pronounced in the PS-matched cohort (before PS matching: DSS, 79%/74%, p=0.0002; OS, 71%/68%, p=0.0269; after PS matching: DSS, 84%/72%, p<0.0001; OS, 75%/66%, p<0.0001). In the entire cohort, the rate of adjuvant therapy was found to be lower in patients with margins ≥5 mm than in those with margins <5 mm (42.7%/57.0%, p<0.0001).ConclusionsWithin the two highest-volume hospitals in Taiwan, patients with OCSCC with a clear margin status (≥5 mm) achieved more favorable outcomes. These results have clinical implications and show how initiatives aimed at improving the margin quality can translate in better outcomes. A clear margin status can reduce the need for adjuvant therapy, ultimately improving quality of life.

Abstract
BackgroundTo assess the prognostic significance of different nodal parameters [i.e., number of pathologically positive nodes, log odds of positive lymph nodes, lymph node ratio (LNR), and extra-nodal extension (ENE)] in Taiwanese patients with oral cavity squamous cell carcinoma (OCSCC), and to devise an optimized pN classification system for predicting survival in OCSCC.MethodsA total of 4287 Taiwanese patients with first primary OCSCC and nodal metastases were enrolled. Cox proportional hazards regression analysis with the spline method was applied to identify the optimal cut-off values for LNR, log odds of positive lymph nodes, and number of pathologically positive nodes.ResultsOn multivariable analysis, we identified a LNR ≥0.078/0.079, the presence of at least three pathologically positive nodes, and ENE as independent prognosticators for 5-year disease-specific survival (DSS) and overall survival (OS) rates. We therefore devised a four-point prognostic scoring system according to the presence or absence of each variable. The 5-year DSS and OS rates of patients with scores of 0−3 were 70%/62%/50%/36% (p <0.0001) and 61%/52%/40%25%, respectively (p <0.0001). On analyzing the AJCC 2017 pN classification, patients with pN3a displayed better survival rates than those with pN2 disease. The 5-year DSS and OS rates of patients with pN1/pN2/pN3a/pN3b disease were 72%/60%/67%/43% (p <0.0001) and 63%/51%/67%/33%, respectively (p <0.0001).ConclusionsThree nodal parameters (i.e., a LNR ≥0.078/0.079, the presence of at least three pathologically positive nodes, and ENE) assessed in combination provided a better prognostic stratification than the traditional AJCC pN classification.

Abstract
OBJECTIVES While the NCCN guidelines maintain that T4b oral cavity squamous cell carcinoma (OCSCC) should undergo either non-surgical treatments or clinical trials, promising outcomes of T4b OCSCC having surgical excision have been reported. We analyzed and compared the clinical outcomes of Taiwanese patients with pT4a and pT4b OCSCC who had undergone surgical treatment. METHODS From 2011 to 2017, a total of 4031 and 355 patients with first primary pT4a and pT4b OCSCC were identified. A propensity score (PS)-matched analysis of patients (n = 351 each) for pT4a and pT4b tumors was also performed. RESULTS The 5-year disease-specific and overall survival (DSS/OS) rates were more favorable in patients with pT4a than in those with pT4b OCSCC (64%/55%, p < 0.0001; 55%/43%, p < 0.0001, respectively). Compared with pT4a, those with pT4b tumors had a higher burden of the following risk factors: buccal/retromolar/hard palate subsite, male sex, depth ≥ 10 mm, and positive margins. Before PS matching, multivariable analyses revealed that pT4b tumors (versus pT4a) were an adverse prognosticator for both 5-year DSS and OS (hazard ratios: 1.32 and 1.39, respectively). However, in the PS-matched cohort, no significant differences in 5-year DSS and OS rates were observed between pT4a and pT4b OCSCC (57%/56%, p = 0.4024; 48%/44%, p = 0.1807, respectively) CONCLUSIONS: No significant outcome differences were evident between pT4b and pT4a OCSCC after PS matching. The most plausible hypothesis for the observed survival difference between T4a and T4b tumors is that it was driven by positive margins. We suggest that T4b OCSCC should undergo initial surgical excision if adequate resection is possible.

Abstract
Simple Summary While the prognostic role of surgical margins in oral cavity squamous cell carcinoma is well-established, the optimal cutoff values for margin status remain controversial. This study addressed this issue in a large sample of 13,768 patients included in a nationwide registry in Taiwan. The identification of the most suitable cutoff value for surgical margins was conducted using 5-year local control as the outcome of interest. On analyzing the margin status—categorized as 0, 0.1–4 and > 4 mm—the 5-year outcomes were as follows: local control, 87, 89 and 92%; disease-specific survival, 57, 76 and 81%; overall survival, 47, 67 and 74%, respectively. Collectively, these data indicate that a margin status >4 mm can be considered as adequate. Abstract (1) Background: The optimal cutoff value that maximizes the prognostic value of surgical margins in patients with resected oral cavity squamous cell carcinoma has not yet been identified. (2) Methods: Data for this study were retrieved from the Taiwan Cancer Registry Database. A total of 13,768 Taiwanese patients with oral cavity squamous cell carcinoma were identified and stratified according to different margin statuses (0, 0.1–4 and > 4 mm). The five-year local control, disease-specific survival and overall survival rates were the main outcome measures. (3) Results: The 5-year local control, disease-specific survival and overall survival rates of patients with close margins (0 and 0.1–4 mm) were significantly lower than those observed in patients with clear margins (> 4 mm; all p values < 0.001). In multivariate analysis, margin status, depth of invasion and extra-nodal extension were identified as independent adverse prognostic factors for 5-year local control. (4) Conclusions: A thorough assessment of surgical margins can provide a reliable prognostic prediction in patients with OCSCC. This has potential implications for treatment approaches tailored to the individual level. The achievement of clear margins (>4 mm) should be considered a key surgical goal to improve outcomes in this patient group.

Abstract
OBJECTIVES The prognosis of pN3b oral cavity squamous cell carcinoma (OCSCC) remains heterogeneous. We sought to improve the prognostic stratification of patients with pN3b OCSCC through a combined analysis of FDG-PET parameters and clinicopathological risk factors (RFs). METHODS From 2001 to 2019, complete data on maximum standardized uptake values derived from FDG-PET of neck metastatic nodes (SUV-nodal-max) and clinicopathological RFs were available for 257 patients with pN3b disease. RESULTS Using the 5-year disease-free survival (DFS) as the outcome of interest, the optimal cutoff points for SUV-nodal-max and lymph node ratio (LNR) were 15.9 and 0.17, respectively. The 5-year DFS rates/(number of cases) for patients with pN3b disease were as follows: SUV-nodal-max < 15.9 versus ≥ 15.9, 49%(226)/21%(31), p = 0.000003; LNR < 0.17 versus ≥ 0.17, 49%(230)/17%(27), p = 0.000117; absence versus presence of neck level IV/V metastases, 49%(230)/15%(27), p = 0.000004. Multivariable analyses revealed that SUV-nodal-max ≥ 15.9, LNR ≥ 0.17, and level IV/V metastases were independent prognosticators for 5-year distant metastases (DM), DFS, disease-specific survival (DSS), and overall survival (OS) rates. Based on these variables, we devised a scoring system that identified three distinct prognostic subgroups at low (score 0, n = 190), intermediate (score 1, n = 51), and high (scores 2-3, n = 16) risk. The 5-year rates of patients with pN3b disease deemed to be at low/intermediate/high risk were as follows: DM, 31%/52%/89%; DFS, 54%/26%/0%; DSS, 59%/36%/8%; OS, 42%/31%/6%, respectively; all p < 0.001. CONCLUSIONS A scoring system based on SUV-nodal-max, LNR, and level IV/V metastases improves the prognostic stratification of OCSCC patients with pN3b disease.

Abstract
Background We compared the clinical outcomes of patients with oral cavity squamous cell carcinoma (OCSCC) with cN+pN0 versus cN0pN0 disease. Methods A total of 1309 OCSCC patients with pN0 disease were included. Of them, 1019 and 290 cases had cN0pN0 and cN+pN0 disease, respectively. For comparison purposes, we also examined 799 patients with pN+disease (cN0pN+/cN+pN+, n = 239/560). Subgroup analysis was performed in a propensity score‐matched cohort with cN0pN0 and cN+pN0 disease (n = 284 each). Results Compared with cN0pN0, patients with cN+pN0 had a higher prevalence of the following variables: betel chewing, pT3−4, depth ≥10 mm, perineural invasion, and treatment with surgery and adjuvant therapy. The prognosis of patients with cN+pN0 (mean: 52 nodes) and cN0pN0 (mean: 39 nodes) disease was similar both in the original cohort and after propensity score matching. However, the 5‐year outcomes were more favorable for cN+pN0/cN0pN0 compared with cN0pN+/cN+pN+ (local control, 88%/88%/83%/81%; neck control, 94%/93%/82%/76%; distant metastases, 4%/3%/13%/31%; disease‐free survival, 84%/83%/68%/52%; disease‐specific survival, 92%/92%/77%/57%; overall survival, 81%/82%/59%/42%; all p values <0.001; cN+pN0 versus cN0pN0, all p values >0.05). cN+pN0 disease (vs. cN0pN0) was not significantly associated with local control, neck control, distant metastases, and survivals either in univariable or multivariable analyses. Conclusions Despite a higher risk factor burden, the prognosis of patients with cN+pN0 disease did not differ from that of cases with cN0pN0. The higher nodal yield and the more frequent use of adjuvant therapy in cN+pN0 disease may explain the lack of significant differences in terms of neck control compared with cN0pN0 disease.

Abstract
Methods We sought to compare the prognostic impact of tumor differentiation with respect to adverse risk factors (RFs) identified by the National Comprehensive Cancer Network (NCCN) guidelines––including extranodal extension (ENE), positive/close margins, perineural invasion, lymphatic invasion, and vascular invasion––in patients with locally advanced oral cavity squamous cell carcinoma (OCSCC). Results Between 1996 and 2018, 1179 consecutive patients with first primary pT3–4 OCSCC were included. A three‐level grading system was adopted––in which the final classification was assigned according to the most prevalent tumor grade. We identified 382/669/128 patients with well/moderately/poorly differentiated tumors, respectively. Compared with well/moderately differentiated tumors, poorly differentiated OCSCC had a higher prevalence of the following variables: female sex (4%/6%/11%), ENE, (14%/36%/61%), positive margins (0.5%/2%/4%), close margins (10%/14%/22%), perineural invasion (22%/50%/63%), lymphatic invasion (2%/9%/17%), vascular invasion (1%/4%/10%), and adjuvant therapy (64%/80%/87%). The 5‐year rates of patients with well/moderately/poorly differentiated OCSCC were as follows: local control (LC, 85%/82%/84%, p = 0.439), neck control (NC, 91%/83%/70%, p < 0.001), distant metastases (DM, 6%/18%/40%, p < 0.001), disease‐free survival (DFS, 78%/63%/46%, p < 0.001), disease‐specific survival (DSS, 85%/71%/49%, p < 0.001), and overall survival (OS, 68%/55%/39%, p < 0.001). Multivariable analysis identified the following variables as independent prognosticators for 5‐year outcomes: ENE (LC/NC/DM/DFS/DSS/OS), poorly differentiated tumors (NC/DM/DFS/DSS/OS), positive margins (LC/DFS), lymphatic invasion (DFS/DSS/OS), perineural invasion (DM), and age ≥65 years (OS). Conclusions In addition to ENE, poor tumor differentiation was identified as the second most relevant adverse RF for patients with pT3–4 OCSCC. We suggest that the NCCN guidelines should include poor tumor differentiation as an adverse RF to refine and tailor clinical management.

Abstract
OBJECTIVES pStage IVB oral cavity squamous cell carcinoma (OCSCC) is defined as either pT4b or pN3 disease. We sought to devise an improved prognostic stratification of this patient group. METHODS Between December 2003 and January 2018, we retrospectively reviewed the clinical records of 1331 consecutive patients with OCSCC who received tumor excision and neck dissection. The number of patients with pT4a/pT4b, pT1N3b/pT2N3b/pT3N3b/pT4N3b, and pStage IVA/IVB was 370/83, 3/49/42/142, and 332/295, respectively. RESULTS The 5-year rates of disease-free survival (DFS) and disease-specific survival (DSS) for patients with pT4a/pT4b disease were 64%/63% (p = 0.973) and 72%/69% (p = 0.672), respectively. The 5-year DFS and DSS rates for patients with pT1N3b/pT2N3b/pT3N3b/pT4N3b disease were 67%/65%/40%/42% (p < 0.001; pT1-2N3b versus pT3-4N3b, p = 0.002) and 100%/68%/45%/49% (p < 0.001; pT1-2N3b versus pT3-4N3b, p = 0.002), respectively. We devised a new definition for pStage IV by considering patients with pT4bN0-2 and pT1-2N3b diseases as pStage-IVA. The number of patients with pStage IVA/IVB (pT3-4N3b) was 443/184. The 5-year rates of AJCC pStage IVA/IVB and the newly proposed pStage IVA/IVB (pT3-4N3b) were as follows: DFS, 74%/52% and 72%/42%; DSS, 83%/58% and 81%/47%; respectively, all p value < 0.001. CONCLUSIONS The clinical outcomes of pT4b and pT4a OCSCC are similar. However, patients with pT3-4N3b disease have a less favorable 5-year prognosis compared with cases with pT1-2N3b. In light of the unfavorable outcomes, pT3-4N3b disease should continue to be classified as pStage IVB. Conversely, pT4bN0-2 and pT1-2N3b diseases portend a less adverse prognosis and should therefore be downstaged to pStage IVA.

Abstract
OBJECTIVES This large-scale cohort study was designed to compare the clinical outcomes of Taiwanese patients with squamous cell carcinoma (SCC) of the upper versus lower gum. METHODS Between 2004 and 2017, we identified 4244 patients with first primary SCC of the gum (694 upper gum; 3550 lower gum) who were treated with surgery either with or without adjuvant therapy. Of them, 1990 patients (329 upper gum; 1661 lower gum) enrolled from 2011 to 2017 had a higher number of histopathological variables and entered subgroup analyses. Five-year disease-specific survival (DSS) and overall survival (OS) rates served as outcome measures. RESULTS The 5-year DSS and OS rates of patients with upper gum SCC were lower than those of cases with lower gum SCC (65%/74%, p < 0.0001; and 55%/65%, respectively, p < 0.0001). Compared with lower gum SCC, upper gum SCC had a higher prevalence of the following variables: female sex, age ≥ 65 years, pNx (without neck dissection), no-betel chewing (2011-2017), no-smoking (2011-2017), and margin status ≤ 4 mm (positive and close margins, 2011-2017). On multivariable analysis, gum subsite (upper versus lower), age (≥65 versus < 65 years), pT (T3 - 4 versus T1 - 2), pN (N1 - 3 versus N0/Nx), depth (≥10 mm versus < 10 mm, 2011-2017), ENE (present versus absent, 2011-2017), and margins (≤4 mm versus > 4 mm 2011-2017, only DSS) were identified as independent adverse prognostic factors for 5-year DSS and OS. CONCLUSIONS Compared to lower gum SCC, upper gum SCC had less favorable 5-year outcomes. Wide resection margins are recommended to improve prognosis of upper gum SCC.

Abstract
OBJECTIVES Mandibular defects involving the central segment are challenging. This study analyzes the impact of defect extent and reconstruction method on quality of life (QOL) and obstructive sleep apnea (OSA). MATERIALS AND METHODS Twenty-nine ameloblastoma patients received segmental mandibulectomy involving the C-segment and immediate fibula free flap reconstruction were recruited. Defects: (C: 2, LC: 11, LCL: 19). Mean defect length: 8.79 cm (± 2.34). Inset: Low-single-barrel (n: 19), with secondary distraction osteogenesis (n: 8/19), high-single-barrel (n: 7), double barrel (n: 3). Patients were surveyed using University of Washington Quality of Life (UW-QOL) and Berlin risk of postoperative sleep apnea questionnaires. RESULTS Flap failure: None. Mean follow-up: 109.6 ± 92.8 months. UW-QOL Physical function 91.83 (± 14.92); social function 90.17 (± 17.19). No statistical difference between C, LC, and LCL was found, but C group which received low-single-barrel had the lowest score in appearance and chewing domains. In health-related QOL (HR-QOL) compared with 1 month before cancer, 69% reported best results. "Appearance" was the most important issue for the past 7 days, followed by "Chewing," prevailing in LC and C groups that predominately reconstructed by low-single-barrel. Berlin score: 7 patients (4 LCL, 3 LC≥8 cm) were at high risk for postoperative OSA. CONCLUSION "Like-with-like" reconstruction with immediate endosteal dental implants yields the best results. Inset of fibula bone could affect outcomes, favoring double-barrel or single-high-barrel inset. Appearance and chewing remain the main concerns, largely, in those with low-single-barrel inset and no dental restoration. After long/extensive LCL and LC mandibulectomies, postoperative OSA warrants further investigation, and modification of resection/reconstruction techniques.

Abstract
OBJECTIVE The objective of this paper is to investigate the incidence rate, risk factors and outcome of osteomyelitis among patients with systemic lupus erythematosus (SLE). MATERIALS AND METHODS We conducted a cohort study using data for patients enrolled in the Taiwan National Health Insurance Database from 2000 to 2012. Patients with SLE and age- and sex-matched controls without SLE were enrolled. Primary endpoint was the first occurrence of osteomyelitis. Risks of osteomyelitis in SLE patients were analyzed with Cox proportional hazards regression models, including age, sex, comorbidities and medications. RESULTS Among 24,705 SLE patients (88.4% women, mean age 35.8 years) with a median follow-up of 9.1 years, 386 patients had osteomyelitis. The incidence rate ratio (IRR) of osteomyelitis in the SLE group vs the control group was 8.52 (95% confidence interval (CI) 7.24-10.05). The SLE group had higher incidence rates of osteomyelitis than the control group, especially in pediatric subgroups (IRR 41.1 95% CI 18.57-107.35). Compared to controls, SLE patients experienced osteomyelitis at a younger age (42.3 vs 58.1 years) but did not have an increased risk of mortality (hazard ratio 0.7; 95% CI 0.21-2.38). Age >60 years, male gender, malignancy within five years, prior bone fracture and higher daily prednisolone dose (>7.5 mg) cumulatively for >180 days increased risk for osteomyelitis. CONCLUSIONS SLE patients have a higher IRR of osteomyelitis than controls. Pediatric and elder SLE patients, patients with a history of bone fracture, malignancy within five years and higher-dose glucocorticoid use have a higher risk of osteomyelitis and should be carefully monitored.

Abstract
Objective The objective of this paper is to analyze the clinical features, outcomes, mortality risk factors, and all-cause mortalities of invasive aspergillosis (IA) in patients with systemic lupus erythematosus (SLE). Methods Medical records were reviewed to identify SLE patients with IA from January 2006 to June 2017, at Taipei Veterans General Hospital, Taiwan. A total of 6714 SLE patients were included. Clinical/laboratory parameters and treatment outcomes were analyzed. Results Four patients (19.0%) had definite and 17 had probable (81.0%) IA. Seven patients (33.3%) survived and 14 died (66.7%). Concurrently, there were 19 pneumonias (90.5%), 17 cases of other infections (81.0%), eight bacteremia (38.1%), nine cytomegalovirus (CMV, 42.7%) and six Candida (28.6%) infections. In all 55 blood cultures, 38 (69.1%) yielded gram-negative bacilli, of which carbapenem-resistant A. baumannii accounted for eight (21.1%); 17 (30.9%) yielded gram-positive cocci, of which methicillin-resistant S. aureus accounted for six (35.3%); and vancomycin-resistant Enterococcus accounted for four (23.5%). Daily steroid dose ≥ 20 mg (hazard ratio (HR) 2.00), recent pulse steroid therapy (HR 2.80), azathioprine (HR 2.00), rituximab (HR 2.00), plasmapheresis (HR 2.00), acute respiratory distress syndrome (HR 2.00), concurrent infections (HR 5.667) and CMV viremia (HR 1.75) were higher in the fatality group. All p values were less than 0.05. Septic shock ( n = 7, 50% in the fatality group) is the most common cause of mortality. Conclusions High daily steroid dosing, recent pulse steroid therapy, azathioprine, rituximab, concurrent infections, and CMV viremia were mortality risk factors for IA in SLE.

Abstract
Objective The objective of this paper is to identify the risk of complications of real-time ultrasound-guided renal biopsy in adult and pediatric patients with systemic lupus erythematosus (SLE). Materials and methods This retrospective study examined outcomes of 296 renal biopsy procedures in 275 SLE patients. Imaging-confirmed symptomatic hematoma was regarded as a major complication when intervention (blood transfusion, angiographic embolization, or surgery) was required or as a minor complication otherwise. Clinical and laboratory data were compared between groups with or without complications after initial or subsequent renal biopsy. Binary logistic regressions were used to evaluate complication risk of initial renal biopsy. Results Overall complication rate of initial renal biopsy was 8.7% (major: 2.9%, minor: 5.8%). Three patients expired from pulmonary hemorrhage, thrombotic microangiopathy, and pneumonia. Pediatric SLE patients tended to have a higher rate of major complications (12.5%) than adult patients (2.3%). According to multivariable analysis results, elevated serum creatinine (SCr) level (OR 1.45; 95% CI 1.17-1.81 per mg/dl), prolonged prothrombin time (PT) (OR 2.2; 95% CI 1.05-4.62 per second), and thrombocytopenia (OR 4.3; 95% CI 1.56-11.9) increased overall complication risk of initial renal biopsy. Age < 18 years (OR 8.43; 95% CI 1.21-58.8), thrombocytopenia (OR 16.4; 95% CI 2.44-110.5), and elevated SCr level (OR 1.97; 95% CI 1.36-2.86 per md/dl) increased risk of major complications. Thrombocytopenia, prolonged PT, and elevated SCr level were associated with complications after subsequent renal biopsy (all p = 0.01). Conclusions SLE patients, particularly patients under 18 years old or with elevated SCr level, prolonged PT, or thrombocytopenia, have an increased risk of complications after initial or subsequent renal biopsy.

Abstract
BACKGROUD/PURPOSE Aggregatibacter actinomycetemcomitans has emerged as one of the aetiological agents in periodontal disease. Although Type IV secretion systems (T4SSs) are widely distributed in many bacteria, the genetic features and distribution of T4SSs in A. actinomycetemcomitans remain unclear. In this study, we investigated the prevalence of A. actinomycetemcomitans serotypes and their T4SSs in a Taiwanese population. METHODS A comparative analysis of 20 A. actinomycetemcomitans genomes and their T4SSs deposited in GenBank was performed. One hundred subjects, including 20 periodontitis and 80 normal subjects, were enrolled and PCR identification of A. actinomycetemcomitans serotypes and T4SS genes were performed. RESULTS Of 100 subjects, serotypes C (22%) and E (11%) were most common. In addition, T4SSs were distributed in all of the serotypes. The prevalence of T4SSs and their location in plasmids in periodontitis subjects were 1.28-2 fold higher but not significantly different compared to normal subjects. Of 20 A. actinomycetemcomitans genomes, only ten with complete T4SS modules could be detected, which was highly correlated with localized aggressive periodontitis (p < 0.1). Nine of ten T4SS modules were from periodontitis subjects. Phylogenetic analysis of 10 T4SSs in A. actinomycetemcomitans showed that they were clustered into two groups, T4SSAaI and T4SSAaII, with only T4SSAaI appearing in the Taiwanese subjects. CONCLUSION A. actinomycetemcomitans strains with different serotypes carrying T4SSAaI are widely distributed in a Taiwanese population. This is the first report to show the distribution and detailed comparative genomics of T4SSs in A. actinomycetemcomitans.

Abstract
The demand for the use of mice as animal models for elucidating the pathophysiologies and pathogeneses of oral motor disorders has been increasing in recent years, as more and more kinds of genetically modified mice that express functional disorders of the stomatognathic system become available. However, the fundamental characteristics of mouse jaw movements during mastication have yet to be fully elucidated. The purpose of this study was to investigate the roles of the masseter and temporalis muscles, and the mechanisms of motor coordination of these muscles for increasing masticatory efficiency in the closing phase in mice. Twenty-two male Jcl:ICR mice were divided into control (n = 8), masseter-hypofunction (n = 7) and temporalis-hypofunction groups (n = 7). Botulinum neurotoxin type A (BoNT⁄A) was used to induce muscle hypofunction. The masticatory movement path in the horizontal direction during the occlusal phase became unstable after BoNT⁄A injection into the masseter muscle. BoNT⁄A injection into the temporalis muscle decreased antero-posterior excursion of the late-closing phase corresponding to the power phase of the chewing cycle. These results suggest that the masseter plays an important role in stabilizing the grinding path, where the food bolus is ground by sliding the posterior teeth from back to front during the occlusal phase. The temporalis plays a major role in retracting the mandible more posteriorly in the early phase of closing, extending the grinding path. Masticatory efficiency is thus increased based on the coordination of activities by the masseter and temporalis muscles.

Abstract
Even with multidisciplinary treatment, the prognosis and quality of life of patients diagnosed with head and neck squamous cell carcinoma (HNSCC) are still not satisfactory. Previously, 19-Nor-2α-(3-hydroxypropyl)-1α,25(OH)2D3 (MART-10), the new brand 1α,25(OH)2D3 analog, has been demonstrated to be an effective drug to inhibit HNSCC growth in vitro. Since most cancer patients die of metastasis, in this study, the antimetastatic effect of MART-10 on HNSCC was investigated. Our results reveal that both 1α,25(OH)2D3 and MART-10 effectively repressed the migration and invasion of HNSCC cells, with MART-10 being much more potent than 1α,25(OH)2D3. The antimetastatic effect of 1α,25(OH)2D3 and MART-10 was mediated by attenuation of epithelial–mesenchymal transition (EMT), which was supported by the finding that the expression of EMT-inducing transcriptional factors, Sail and Twist, was inhibited by 1α,25(OH)2D3 and MART-10. The upregulation of E-cadherin and downregulation of N-cadherin in FaDu cells induced by both drugs further confirmed the repression of EMT. In addition, 1α,25(OH)2D3 and MART-10 treatment inhibited intracellular MMP-9 expression and extracellular MMP activity in FaDu cells. Collectively, our results suggest that the less-calcemia 1α,25(OH)2D3 analog, MART-10, is a promising drug for HNSCC treatment. Further clinical studies are warranted.

Abstract
OBJECTIVES To investigate changes in masseter muscle function following intramuscular injection of different dose-dependent botulinum toxin type A (BTXA). SETTING AND SAMPLE POPULATION Department of Orthodontics at Taipei Medical University. Fifty-two, 70-day-old male Wistar rats were randomly divided into four groups. Group I received 7.5 U of BTXA (0.3 ml), Group II received 5.0 U, and Group III received 2.5 U in the right masseter muscle, respectively. Group IV is the control and received no BTXA injection. MATERIALS AND METHODS A wire electrode device was implanted to record muscle activity. One week after implantation, the rats were fed every 2 h and EMG signals were recorded during the first hour. All signals were recorded for 12 weeks. Thereafter, EMG data were analyzed for statistical calculation and weights of masseter muscles were measured. RESULTS Masseter muscle activity decreased 99% during the first week after BTXA injection and gradually recovered from the 3rd week on in Groups I-III. By the 12th week, muscle activity recovered to 41% in Groups I and II and 56.26% in Group III. No significant changes of muscle activity were observed in Group IV. CONCLUSION BTXA induced a reduction in masseter muscle activity and an increased toxin dose resulted in greater depression of muscle activity.

Abstract
AbstractHead and neck cancer (HNC) is a prevalent cancer worldwide; however, clinically useful tumor markers for HNC have not been identified. Here, we aimed to identify secretory proteins from the tumor microenvironment as candidate circulating tumor markers.Samples derived from seven pairs of tumor interstitial fluid (TIF) and normal interstitial fluid (NIF) samples from patients with HNC were analyzed. The proteomes were determined by gel-based-mass-spectrometry proteomic methods. The most up-regulated protein, fascin was confirmed in the cancer tissues and cell culture supernatant by immunoblotting and immunohistochemistry assays. Serum fascin was determined in 40 HNC and 40 normal individuals by ELISA.After proteomics analysis, 189 peptides were identified, corresponding to 75 proteins. Of the 21 proteins which were identified more than twice, five up-regulated proteins identified most frequently including fascin. The most elevated fascin was over-expressed in cancer tissues and cell culture supernatant. Serum fascin was significantly up-regulated in the cancer patients (p<0.001) and correlated with pathological lymph node metastasis (p=0.022). To assess the diagnostic efficacy, serum levels of fascin and another potential biomarker SCCA were determined. Fascin showed a high predictable value with an area under the curve (AUC) of 0.808 (95% CI 0.723–0.901) in the receiver operator curve (ROC), compared to 0.501 (95% CI 0.378–0.634) for SCCA.We have identified 75 potential circulating tumor markers associated with HNC, including fascin. Serum fascin could discriminate cancer patients from healthy individuals; thus, it may serve as a circulating biomarker for HNC.

Abstract
Background MicroRNA-196 (miR-196), which is highly up-regulated in oral cancer cells, has been reported to be aberrantly expressed in several cancers; however, the significance of miR-196 in oral cancer has not yet been addressed. Methods Cellular functions in response to miR-196 modulation were examined, including cell growth, migration, invasion and radio/chemosensitivity. Algorithm-based studies were used to identify the regulatory target of miR-196. The miR-196 target gene and downstream molecular mechanisms were confirmed by RT-qPCR, western blot, luciferase reporter and confocal microscopy analyses. miR-196 expression was determined in paired cancer and adjacent normal tissues from oral cancer patients. Results Both miR-196a and miR-196b were highly over-expressed in the cancer tissue and correlated with lymph node metastasis (P = 0.001 and P = 0.006, respectively). Functionally, miR-196 actively promoted cell migration and invasion without affecting cell growth. Mechanistically, miR-196 performed it's their function by inhibiting NME4 expression and further activating p-JNK, suppressing TIMP1, and augmenting MMP1/9. Conclusion miR-196 contributes to oral cancer by promoting cell migration and invasion. Clinically, miR-196a/b was significantly over-expressed in the cancer tissues and correlated with lymph node metastasis. Thus, our findings provide new knowledge of the underlying mechanism of cancer metastasis. miR-196 may serve as a promising marker for better oral cancer management.

Abstract
Hec1 (highly expressed in cancer 1) or Nek2 (NIMA-related kinase 2) is often overexpressed in cancers with poor prognosis. Both are critical mitotic regulators, and phosphorylation of Hec1 S165 by Nek2 is required for proper chromosome segregation. Therefore, inactivation of Hec1 and Nek2 by targeting their interaction with small molecules represents an ideal strategy for tackling these types of cancers. Here we showed that new derivatives of INH (inhibitor for Nek2 and Hec1 binding) bind to Hec1 at amino acids 394-408 on W395, L399 and K400 residues, effectively blocking Hec1 phosphorylation on S165 by Nek2, and killing cancer cells at the nanomolar range. Mechanistically, the D-box (destruction-box) region of Nek2 specifically binds to Hec1 at amino acids 408-422, immediately adjacent to the INH binding motif. Subsequent binding of Nek2 to INH-bound Hec1 triggered proteasome-mediated Nek2 degradation, whereas the Hec1 binding defective Nek2 mutant, Nek2 R361L, resisted INH-induced Nek2 degradation. This finding unveils a novel drug-action mechanism where the binding of INHs to Hec1 forms a virtual death-trap to trigger Nek2 degradation and eventually cell death. Furthermore, analysis of the gene expression profiles of breast cancer patient samples revealed that co-elevated expressions of Hec1 and Nek2 correlated with the shortest survival. Treatment of mice with this kind of tumor with INHs significantly suppressed tumor growth without obvious toxicity. Taken together, the new INH derivatives are suitable for translation into clinical application.

Abstract
OBJECTIVES In T1, T2, and clinically NO squamous cell carcinoma of the tongue, there is no reliable predictive variable to determine whether or not neck dissection is needed. Thus, we established a predictive score model based on tumour depth and other pathological variables. METHODS We retrospectively reviewed 115 patients with T1 and T2 stage squamous cell carcinoma of the tongue. Their pathological variables were used to construct a score model for predicting the risk of cervical lymph node metastasis. RESULTS A predictive score model was proposed using multivariate logistic regression analysis: Score = (2.694 x tumour depth (cm)) + (1.814 x lymphovascular invasion (yes = 1, no = 0)) + (1.175 x perineural invasion (yes = 1, no = 0)). The cutoff point was set at 2.7427. This predictive score model has a sensitivity of 91.2% and specificity of 65.4%. CONCLUSION A predictive score model was built and a two-stage surgical approach was suggested for T1 and T2 squamous cell carcinoma of the tongue.

Abstract
OBJECTIVES The aim of this cohort study was to examine the role of chemokine (C-X-C motif) ligand 9 (CXCL9) on oral cavity squamous cell carcinoma (OSCC). METHODS Sera from 181 OSCC patients, 231 healthy individuals, and 50 OSCC tumor samples were enrolled. CXCL9 expression in tissue samples was analyzed by quantitative real-time PCR and immunohistochemistry. CXCL9 serum concentrations were measured by enzyme-linked immunosorbent assay. Effects of CXCL9 on OSCC cell function were investigated by cell proliferation assays, trans-well migration/invasion assays, and RNA interference. RESULTS CXCL9 expression was significantly higher than for normal epithelium in the tissue samples. CXCL9 serum concentrations were also significantly higher in OSCC patients compared to those in healthy individuals. Serum CXCL9 levels were significantly higher in OSCC patients with higher pT status, pathological overall stages, tumor depths, and positive bone invasion (P = 0.033, 0.004, 0.041, and 0.002, respectively). Moreover, OSCC patients with higher CXCL9 levels (> 209 pg/mL, median level) before treatment had worse prognoses for overall survival and disease-specific survival (P = 0.0006 and 0.0009, respectively). Multivariate logistic regression analyses also indicated that higher CXCL9 serum levels were an independent prognostic factor for overall survival and disease-free survival (P = 0.003 and 0.004, respectively). The in vitro suppression of CXCL9 expression in SCC25 cells using specific interfering RNAs attenuated cell proliferation, migration and invasiveness. CONCLUSIONS Our study demonstrated that CXCL9 is associated with tumor burden and aggressiveness of OSCC tumors and serum level of this ligand may be useful as a prognostic indicator.

Abstract
Protein-losing enteropathy (PLE) and autoimmune oophoritis are unusual manifestations of systemic lupus erythematosus (SLE). Autoimmune oophoritis may result in menstrual disturbance and spontaneous premature ovarian failure. However, there is no validated examination to confirm the diagnosis and it is easily neglected in patients with ovarian insufficiency. A 31-year-old woman with SLE presented with PLE and autoimmune oophoritis during the long course of flares and remissions in her lupus activity. The synchronism implied the association between the two. Moreover, both conditions simultaneously had a good response to cyclosporine A (CsA) therapy.

Abstract
Molecular methods for predicting prognosis in patients with oral cavity squamous cell carcinoma (OSCC) are urgently needed, considering its high recurrence rate and tendency for metastasis. The present study investigated the genetic basis of variations in gene expression associated with poor prognosis in OSCC using Affymetrix SNP 6.0 and Affymetrix GeneChip Human Gene 1.0 ST arrays. We identified recurrent DNA amplifications scattered from 8q22.2 to 8q24.3 in 112 OSCC specimens. These amplicons demonstrated significant associations with increased incidence of extracapsular spread, development of second primary malignancies, and poor survival. Fluorescence in situ hybridization, in a validation panel consisting of 295 cases, confirmed these associations. Assessment of the effects of copy number variations (CNVs) on genome-wide variations in gene expression identified a total of 85 CNV-associated transcripts enriched in the MYC-centered regulatory network. Twenty-four transcripts associated with increased risk of second primary malignancies, tumor relapse, and poor survival. Besides MYC itself, a novel dysregulated MYC module plays a key role in OSCC carcinogenesis. This study identified a candidate molecular signature associated with poor prognosis in OSCC patients, which may ultimately facilitate patient-tailored selection of therapeutic strategies.

Abstract
BACKGROUND AND PURPOSE Platelet hyperactivity is important in the pathogenesis of cardiovascular diseases. Betel leaf (PBL) is consumed by 200-600 million betel quid chewers in the world. Hydroxychavicol (HC), a betel leaf component, was tested for its antiplatelet effect. EXPERIMENTAL APPROACH We tested the effect of HC on platelet aggregation, thromboxane B(2) (TXB(2)) and reactive oxygen species (ROS) production, cyclooxygenase (COX) activity, ex vivo platelet aggregation and mouse bleeding time and platelet plug formation in vivo. The pharmacokinetics of HC in rats was also assessed. KEY RESULTS HC inhibited arachidonic acid (AA) and collagen-induced platelet aggregation and TXB(2) production. HC inhibited the thrombin-induced TXB(2) production, but not platelet aggregation. SQ29548, suppressed collagen- and thrombin-induced TXB(2) production, but not thrombin-induced platelet aggregation. HC also suppressed COX-1/COX-2 enzyme activity and the AA-induced ROS production and Ca(2+) mobilization. HC further inhibited the ex vivo platelet aggregation of platelet-rich plasma (>100 nmole/mouse) and prolonged platelet plug formation (>300 nmole/mouse) in mesenteric microvessels, but showed little effect on bleeding time in mouse tail. Moreover, pharmacokinetics analysis found that more than 99% of HC was metabolized within 3 min of administration in Sprague-Dawley rats in vivo. CONCLUSIONS AND IMPLICATIONS HC is a potent COX-1/COX-2 inhibitor, ROS scavenger and inhibits platelet calcium signaling, TXB(2) production and aggregation. HC could be a potential therapeutic agent for prevention and treatment of atherosclerosis and other cardiovascular diseases through its anti-inflammatory and antiplatelet effects, without effects on haemostatic functions.

Abstract
BACKGROUND Oral cancer patients receive wide excision of oral structures and reconstruction of the intraoral defects with skin grafts and/or local, regional, or free flaps. Trismus is a common postoperative sequela, even without postoperative radiotherapy. Trismus decreases patients' quality of life and can have detrimental effects on their oral hygiene and nutritional status. METHODS Between May of 1999 and June of 2003, 11 patients were operated on for release of trismus and reconstruction after previous intraoral reconstructions. The patients had been reconstructed with skin grafts (n = 4), radial forearm flaps (n = 3), anterolateral thigh flaps (n = 1), artificial dermis (n = 1), radial forearm flaps with skin grafts (n = 1), and pedicled pectoralis major flaps with skin grafts (n = 1). Eight patients had received postoperative radiotherapy. The patients presented with a mean interincisal distance of 3.1 mm (range, 0 to 10 mm). RESULTS After trismus release, the intraoral soft-tissue defects were reconstructed with one or two free flaps (six anterolateral thigh flaps, nine forearm flaps, and one fibula osteoseptocutaneous flap). Fifteen of the 16 flaps were successful, with one flap failure. Average interincisal distance was 33.4 mm immediately after the release (range, 27 to 35 mm) and 18.9 mm (range, 5 to 30 mm) at a mean follow-up time of 22.7 months (16.1 mm in the radiated group and 26.3 mm in the nonradiated group). The mean amount of improvement was 15.8 mm. CONCLUSION The use of free flaps to reconstruct the defects created after trismus release in patients with previous intraoral reconstruction is a viable option that yields reasonable, long-lasting improvements in mouth opening, intraoral hygiene, and quality of life.

Abstract
Maxillary ameloblastoma is a benign odontogenic neoplasm. Excision should involve wide margins because of its high recurrence rate and, ideally, be followed by reconstruction. A 23 year-old female patient presented with recurrent ameloblastoma. Two years previously, she had undergone a curettage excision. The recurrent lesion was managed by a total maxillectomy including inferior orbital rim. Simultaneous reconstruction was performed with an iliac crest bone graft for the orbital floor, and a vastus lateralis muscle flap for obliteration of the maxillary sinus and repair the oral and nasal cavities. The transferred vastus lateralis muscle already had spontaneous mucosalization over its surface two weeks after surgery. Postoperative follow up after fourteen months revealed no recurrence and no diplopia. The patient was satisfied with her appearance. The use of a single vastus lateralis muscle flap to repair both oral and nasal cavities is advantageous. It helps avoid hyper-nasal speech and maintain the stability of removable partial dentures. The conventional iliac bone graft supported by a well vascularized muscle eventually survived and provided a good functional and cosmetic result.

Abstract
Anti-neutrophil cytoplasmic antibodies (ANCA) not only are triggered by target protein myeloperoxidase (MPO) and proteinase 3 (PR3) of polymorphonuclear neutrophil (PMN) but also react with primed PMN to exert the inflammatory process in vasculitis syndrome. To clarify the crucial role of PMN in ANCA-associated vasculitis and the related mechanism, PMN was cultured with monoclonal antibody MPO-ANCA and PR3-ANCA to determine the function of phagocytosis, Interleukin- 8 (IL-8) production, glucose uptake, and TNF-related apoptosis induced ligand (TRAIL) production. The spontaneous membrane expression of MPO and PR3 on PMN could be significantly increased by lipopolysaccharide (LPS) and TNF-alpha, but not by IL-8 or GRO-alpha. The PMN-stimulating activity of ANCA was demonstrated by enhancing phagocytosis, IL-8 production, and glucose uptake that was more prominent by MPO-ANCA. The PMN stimulation by ANCA was not through protein kinase, H2O2, or superoxide anion radicals as their inhibitors exerted no effect on ANCA-mediated activation. On the other hand, ANCA also accelerated PMN apoptosis and increased TRAIL production. These results demonstrate that activation-induced cell death (AICD) mechanism could be initiated in PMN with existence of ANCA. In conclusion, MPO-ANCA is more potent in stimulating PMN than PR3-ANCA. ANCA-activated PMN is not only responsible for the amplified inflammatory process in blood vessel but also initiates immune circuit via triggered macrophage/monocyte by apoptotic PMN through the mechanism of AICD elicited by ANCA.

Abstract
Segmental resection of the mandible leads to significant patient morbidity. Loss of mandibular support to the teeth, tongue and lip causes dysfunctional mastication, swallowing, speech, airway protection and oral competence. Patients also suffer disfigurement following segmental mandibulectomy because the mandible is an important aesthetic landmark. The degrees to which dysfunction and disfigurement occur depend both on the location of the mandibular segment removed and the amount of surrounding soft tissue excised. Between January 1985 and December 2004, 780 fibula osteoseptocutaneous flaps have been used for head and neck reconstruction at the Chang Gung Memorial Hospital, Taiwan. The fibula flap has proven to be the bony flap of choice because it has a lengthy bicortical segment of bone available, a reasonably long vascular pedicle, large diameter vessels, good bone quality, and is easily contoured with multiple osteotomies. The flap can be harvested while ablation is being performed. In addition, a reliable, mobile, thin skin component can always be included to address the soft tissue reconstructive requirements. A chimeric design employing a portion of the soleus muscle can provide further reconstructive options. Ideally complete rehabilitation of the mandible involves placement of titanium osseointegrated implants, which allow dental restoration. Primary placement of implants is preferred in patients without cancer. Selection of candidates to receive osseointegrated implants is paramount. The temporomandibular joint remains a challenge to reconstruct adequately.

Abstract
BACKGROUND The treatment of severe trismus requires a combination of surgical release and postoperative rehabilitation; the latter is essential for preventing a relapse due to postoperative inactivity and scarring. Mouth-opening devices for this purpose are placed between or fixed to the teeth to keep the dental arches apart; but patients suffering from severe trismus often present with partially or totally edentulous arches, decayed teeth, or periodontitis, which do not allow for the use of such devices. METHODS In this article, a new mouth-opening device is described. It applies force to two intraoral screws placed in the vestibulum of the maxillary and mandibular bones. It can be used in patients with poor dental conditions and allows rehabilitation to start immediately after trismus release. RESULT A case is presented. The interalveolar distance was improved from 5 mm to 45 mm and maintained at 6-month follow-up. CONCLUSION Our non-tooth-borne mouth opening device is useful for postoperative rehabilitation after surgical release of trismus.

Abstract
OBJECTIVE To evaluate the changes in anti-cyclic citrullinated peptide antibodies (anti-CCP) and rheumatoid factor (RF) following etanercept treatment in patients with rheumatoid arthritis. METHODS The study included 90 patients with rheumatoid arthritis who failed treatment with disease modifying antirheumatic drugs (DMARDs). All patients were allowed to continue treatment with DMARDs; 52 of them received etanercept as a twice weekly 25 mg subcutaneous injection for three months, and the others did not. Serum samples were collected at baseline and one month intervals during the treatment course. The serum levels of anti-CCP and RF were tested by enzyme linked immunosorbent assay and nephelometry, respectively. RESULTS At baseline, 45 of the 52 etanercept treated patients (86.5%) and 32 of the 38 controls (84.2%) were positive for anti-CCP. Tests for RF were positive in 78.9% and 84.2% of patients with or without etanercept treatment, respectively. The serum levels of anti-CCP and RF decreased significantly after a three month etanercept treatment (p = 0.007 and p = 0.006, respectively). The average decrease from baseline calculated for each individual patient in the etanercept treated group was 31.3% for anti-CCP and 36% for RF. The variation in anti-CCP was positively correlated with the variation in disease activity, swollen and tender joint counts, RF, and C reactive protein. CONCLUSIONS Etanercept combined with DMARDs leads to a much greater decrease than DMARDs alone in the serum levels of anti-CCP and RF in rheumatoid arthritis, compatible with a reduction in clinical disease activity.

Abstract
The organophosphate insecticide mevinphos (Mev) acts on the rostral ventrolateral medulla (RVLM), where sympathetic vasomotor tone originates, to elicit phasic cardiovascular responses via nitric oxide (NO) generated by NO synthase (NOS) I and II. We evaluated the contribution of soluble guanylyl cyclase (sGC)/cyclic guanosine monophosphate (cGMP)/protein kinase G (PKG) cascade and peroxynitrite in this process. PKG expression in ventrolateral medulla of Sprague-Dawley rats manifested an increase during the sympathoexcitatory phase (Phase I) of cardiovascular responses induced by microinjection of Mev bilaterally into the RVLM that was antagonized by co-administration of 7-nitroindazole or Nomega-propyl-L-arginine, two selective NOS I inhibitors or 1-H-[1,2,4]oxadiaolo[4,3-a]quinoxalin-1-one (ODQ), a selective sGC antagonist. Co-microinjection of ODQ or two PKG inhibitors, KT5823 or Rp-8-Br-cGMPS, also blunted the Mev-elicited sympathoexcitatory effects. However, the increase in nitrotyrosine, a marker for peroxynitrite, and the sympathoinhibitory circulatory actions during Phase II Mev intoxication were antagonized by co-administration of S-methylisothiourea, a selective NOS II inhibitor, Mn(III)-tetrakis-(4-benzoic acid) porphyrin, a superoxide dismutase mimetic, 5,10,15,20-tetrakis-N-methyl-4'-pyridyl)-porphyrinato iron (III), a peroxynitrite decomposition catalyst, or L-cysteine, a peroxynitrite scavenger. We conclude that sGC/cGMP/PKG cascade and peroxynitrite formation may participate in Mev-induced phasic cardiovascular responses as signals downstream to NO generated respectively by NOS I and II in the RVLM.

Abstract
Thirty patients with trismus resulting from betel nut chewing-induced oral submucous fibrosis were treated with either fibrotic tissue release only (group I) or fibrotic tissue release in combination with masticatory muscle myotomy and coronoidotomy (group II). The latter procedures were only performed in patients whose intraoperative interincisal distance remained less than 35 mm immediately after submucous fibrous tissue release. There were eight and 22 patients in groups I and II, respectively. In group I patients, the average intraoperative interincisal distance improved from 19.5 mm to 42 mm. In group II patients, the average intraoperative interincisal distance improved from 13.5 mm to 27 mm after fibrotic tissue release and further improved to 40 mm after masticatory muscle myotomy and coronoidotomy. At an average follow-up of 22.1 months (range, 7 to 70 months), the group I and II patients had an average interincisal distance of 41.5 mm (range, 35 to 50 mm) and 32.9 mm (range, 20 to 42 mm), respectively. These results demonstrate the efficacy of submucous fibrotic tissue release in treating trismus resulting from betel nut chewing-induced submucous fibrosis and confirm the role of additional masticatory muscle and coronoidotomy in treating its severe forms.

Abstract
OBJECTIVES Carriage of HLA-B60 has been shown to increase the risk of ankylosing spondylitis (AS) in B27-positive Caucasian patients, but the association in B27-negative cases is less certain. This study assessed HLA class I gene associations in Chinese HLA-B27-negative AS patients. METHODS Forty-one Chinese HLA-B27-negative AS patients fulfilling the modified New York diagnostic criteria for AS were recruited, and 11 383 HLA-B27-negative blood donors were used for comparison. HLA-A and -B typing was done with the microlymphocytotoxicity assay. RESULTS Among the B27-negative AS patients, 21 were male and 20 were female. Of HLA-B alleles, only B60 and B61 significantly increased susceptibility to AS in HLA-B27-negative patients (P<0.001). CONCLUSIONS In Taiwan Chinese, carriage of B60 is increased in HLA-B27-negative AS patients. The association between B61 and HLA-B27-negative AS patients has not been reported previously. Whether the gene involved is HLA-B60 or B61 or another gene in linkage disequilibrium with these genes is unknown.

Abstract
The fibula osteoseptocutaneous flap is a good option for reconstruction of three-dimensional composite maxillary defects. This flap provides both bone and soft-tissue reconstruction and allows osseointegrated dental implantation, either simultaneously or in a second-stage procedure. Simultaneous placement of osseointegrated dental implants reduces operative sessions and allows faster oral rehabilitation for properly selected patients. The defects may result from trauma or resection of benign tumors or low-grade malignancies. Between August of 1999 and July of 2001, three patients underwent maxillary reconstruction with the fibula osteoseptocutaneous flap and simultaneous osseointegrated dental implants. The cause of the defect was trauma in two cases and resection of an adenoid cystic carcinoma in the other. The mean length of the fibula used for bony reconstruction was 4.7 cm. One osteotomy was performed in one case and no osteotomy was necessary in the other two. Skin islands of 8 x 2.5 cm and 16 x 3.5 cm were used for two patients. For the other patient, a double skin island was used for both nasal (6 x 4 cm) and oral (6 x 5 cm) reconstructions. Two osseointegrated implants were inserted into the fibular bone for each patient. Six months after the first-stage procedure, palatal rotation flaps or mucosa grafts were used to cover the exposed implant necks and prepare the implants for prostheses. One month after the second-stage procedure, prostheses were placed. An implant-supported prosthesis was used for one patient and implant/tissue-supported prostheses were used for the others. At a mean follow-up time of 30 months (range, 16 to 38 months), all patients were able to use the dental prosthesis for chewing (beginning 6 weeks after the final procedure) and all patients were satisfied with the cosmetic results.

Abstract
Thirteen patients with large ameloblastomas of the mandible underwent segmental mandibulectomy and immediate reconstruction, with simultaneous placement of osseointegrated implants. All patients received palatal mucosal grafts around the dental implants 6 to 10 months after surgical treatment and received implant-supported prostheses another 1 to 2 months later. There were five female and eight male patients, with a mean age of 32 years (range, 17 to 50 years). The mean length of the mandibular defect was 8.8 cm (range, 5 to 13 cm). All free fibula flap procedures were successful, with no reexplorations or partial flap losses. There was no clinical or radiographic evidence of failure during the osseointegration process for any implant. With functional occlusal loading, the marginal bone loss around the implants was less than 1.5 mm in a mean follow-up period of 40 months (range, 18 to 70 months). There were no recurrences during that time. The technique described allows improved access to the bone at the time of reconstruction, immediate assessment of alveolar ridge relationships, and accurate fixation of the implant-fibula construct. The advantages of this procedure include a reduced risk of recurrence with segmental resection, reliable mandibular reconstruction, and reduction of the number of surgical procedures, allowing full oral rehabilitation in a shorter time. It is concluded that segmental mandibulectomy and immediate vascularized fibula osteoseptocutaneous flap reconstruction, with simultaneous placement of osseointegrated implants, represent an ideal treatment method for large ameloblastomas of the mandible.
