Abstract
PURPOSE The concept of oligometastasis, which represents limited metastatic disease, has recently gained interest, accompanied by a more detailed classification. This study aims to investigate the relationship between the treatment course and prognosis in patients with a recurrence of esophageal squamous cell carcinoma (ESCC) after curative esophagectomy. METHODS 126 patients with ESCC recurrence after curative resection were enrolled in this study. Oligometastasis was defined as fewer than five recurrences in a single organ. Patients were classified as having oligometastatic recurrence (OLR) or polymetastatic recurrence (PLR). Patients were further classified into four subgroups according to lesion progression: persistent oligorecurrence (PER-OLR), converted polyrecurrence (CON-PLR), induced oligorecurrence (IND-OLR), and persistent polyrecurrence (PER-PLR). We analyzed the relationship between the recurrence patterns and prognosis according to the progression of oligometastatic lesions. RESULTS OLR was identified in 58 (46%) of 126 patients with recurrence. Patients with OLR had a significantly better prognosis than those with PLR (P < 0.0001). A further subgroup analysis revealed that patients who underwent IND-OLR had a similar prognosis to those who underwent PER-OLR. CONCLUSIONS This study suggests that OLR is a prognostic factor after recurrence following resection of ESCC and that PLR can be converted to OLR by therapeutic intervention to achieve a long-term survival.

Abstract
BACKGROUND Obesity is associated with increased mortality in various cancers, but the relationship between obesity and clinical outcomes in unresectable or recurrent esophageal cancer who receive immune checkpoint inhibitors (ICIs) remains unknown. This study investigated the association between body composition and clinical outcomes in patients with unresectable or recurrent esophageal cancer who received ICIs. METHODS Utilizing an unbiased database of 111 unresectable or recurrent esophageal cancers, we evaluated the relationships between body composition (body mass index, waist circumference, psoas major muscle volume, and subcutaneous and visceral fat areas) at the initiation of ICI treatment and clinical outcomes including the disease control rate and progression-free survival (PFS). RESULTS Waist circumference was significantly associated with the disease control rate at the first assessment (P = 0.0008). A high waist circumference was significantly associated with favorable PFS in patients treated with nivolumab. In an univariable model, for 5-cm increase of waist circumference in the outcome category of PFS, univariable hazard ratio (HR) was 0.73 (95% confidence interval [CI], 0.61-0.87; P = 0.0002). A multivariable model controlling for potential confounders yielded a similar finding (multivariable HR, 0.56; 95% CI, 0.33-0.94; P = 0.027). We observed the similar finding in esophageal cancer patients treated with pembrolizumab+CDDP+5-FU (P = 0.048). In addition, waist circumference was significantly associated with the prognostic nutritional index (P = 0.0073). CONCLUSIONS A high waist circumference was associated with favorable clinical outcomes in ICI-treated patients with unresectable or recurrent esophageal cancer, providing a platform for further investigations on the relationships among body composition, nutrition, and the immune status.

Abstract
BACKGROUND Chronic obstructive pulmonary disease (COPD) prevalence increases post-esophagectomy morbidity. However, the association between COPD severity and post-esophagectomy morbidity remains unclear because of the lack of an objective method to classify COPD severity. Low attenuation volume ratio (LAVR) estimated using Ziostation2 may reflect the extent of emphysematous changes in the lungs and COPD severity, thereby predicting post-esophagectomy morbidity. METHODS A total of 776 patients who underwent curative McKeown esophagectomy for esophageal cancer between April 2005 and June 2021 were included. The patients were divided into high and low preoperative LAVR groups. Short-term outcomes between the groups were compared for patients who underwent open esophagectomy (OE) and minimally invasive esophagectomy (MIE). RESULTS A total of 219 (28%) patients were classified into the high LAVR group. High LAVR was significantly associated with disadvantageous patient characteristics such as advanced age, heavy smoking, and impaired respiratory function. Patients with high LAVR had a significantly higher incidence of severe morbidity and pneumonia after OE. High LAVR was an independent risk factor for severe morbidity (odds ratio [OR], 2.52; 95% confidence interval [CI]: 1.237-5.143; p = 0.011) and pneumonia (OR, 2.12; 95% CI: 1.003-4.493; p = 0.049) after OE. Meanwhile, LAVR was not correlated with the incidence of post-MIE morbidity. CONCLUSIONS LAVR may reflect COPD severity and predict severe morbidity and pneumonia after OE, but not after MIE. Less invasiveness of MIE may alleviate the effects of various disadvantageous backgrounds associated with high LAVR on worse short-term outcomes.

Abstract
BACKGROUND Increased 18F-fluorodeoxyglucose (FDG) uptake in the bone marrow (BM) on positron emission tomography/computed tomography (PET/CT) clinically reflects increased BM metabolism owing to systemic inflammation, bacterial infection, anemia, and cytokine-producing tumors. The association between FDG uptake in the BM and prognosis after esophagectomy for esophageal cancer has not been investigated. METHODS This study included 651 patients who underwent PET/CT before any treatment and McKeown esophagectomy for esophageal cancer between June 2007 and August 2021. The pretreatment degree of FDG uptake in the BM was evaluated using a visual assessment criterion. Patients were divided into low- and high-FDG uptake groups. We retrospectively investigated whether the degree of FDG uptake in the BM was associated with clinicopathological and surgical backgrounds, blood parameters, and prognosis. RESULTS High FDG uptake in the BM was significantly associated with elevated white blood cell and neutrophil counts, increased C-reactive protein levels, decreased hemoglobin, serum albumin, and total cholesterol levels. High FDG uptake in the BM was an independent predictor of worse overall survival in clinical stages 0-II esophageal cancer (hazard ratio, 2.27; 95% confidence interval, 1.097-4.695; P = 0.027). Worse overall survival was also associated with advanced age, low American Society of Anesthesiologists physical status, an advanced clinical stage, and high intraoperative blood loss. CONCLUSION Increased FDG uptake in the BM on pretreatment PET/CT may be a surrogate indicator of various clinically disadvantageous backgrounds and may act as a predictor of poor prognosis after esophageal cancer surgery.

Abstract
BACKGROUND We previously demonstrated the relationship of human microbiome Fusobacterium nucleatum with unfavorable clinical outcomes and inferior chemotherapeutic responses in esophageal cancer. Global DNA methylation is associated with the occurrence and development of various cancers. In our previous study, LINE-1 hypomethylation (i.e., global DNA hypomethylation) was associated with a poor prognosis in esophageal cancer. As the gut microbiota may play crucial roles in the DNA methylation of host cells, we hypothesized that F. nucleatum might influence LINE-1 methylation levels in esophageal cancer. METHODS We qualified the F. nucleatum DNA using a quantitative PCR assay and LINE-1 methylation via a pyrosequencing assay using formalin-fixed paraffin-embedded specimens from 306 esophageal cancer patients. RESULTS Intratumoral F. nucleatum DNA was detected in 65 cases (21.2%). The LINE-1 methylation scores ranged from 26.9 to 91.8 (median = 64.8) in tumors. F. nucleatum DNA was related to the LINE-1 hypomethylation of tumor lesions in esophageal cancer (P < 0.0001). The receiver operating characteristic curve analysis showed that the area under the curve was 0.71 for F. nucleatum positivity. Finally, we found that the impact of F. nucleatum on clinical outcomes was not modified by LINE-1 hypomethylation (P for interaction = 0.34). CONCLUSIONS F. nucleatum alters genome-wide methylation levels in cancer cells, which may be one of the mechanisms by which F. nucleatum affects the malignant behavior of esophageal cancer.

Abstract
PURPOSE Textbook outcome (TO) is a composite quality measurement of short-term outcomes for evaluating surgical procedures. We investigated whether TO can be used to predict outcomes after curative gastric cancer (GC) surgery in older adults. METHODS We retrospectively analyzed 492 consecutive patients who underwent curative gastrectomy for GC from 2005 to 2017. Among these, 141 advanced-age patients were eligible. The patients were divided into two groups: those who achieved TO (a-TO group) and those who failed to achieve TO (f-TO group). In accordance with previous reports, TO consisted of eight metrics. We evaluated the association between TO and long-term survival. RESULTS TO was achieved 73 (52%) patients. The patients in the f-TO group had a significantly higher body mass index (P = 0.01), longer surgery time (P = 0.03), and more blood loss (P = 0.001). The metric with the lowest achievement rate was "no postoperative severe complication." The patients in the f-TO group had significantly shorter overall survival than those in the a-TO group (P = 0.03). Multivariable Cox regression analyses of overall survival revealed that an American Society of Anesthesiologists physical status classification of 3 (hazard ratio [HR], 3.28; 95% confidence interval [CI], 1.79-5.98; P < 0.0001) and f-TO (HR, 1.92; 95% CI, 1.09-3.39; P = 0.02) were significantly associated with poor overall survival. CONCLUSION TO can be used to predict outcomes after curative GC surgery in patients of advanced age.

Advanced diagnostic imaging revealed a thrombus in the splenic and portal veins. For the portal vein thrombus, CT angiography showed an enhanced timing delay in the lateral right and caudate liver lobes. Blood tests showed a marked increase in the liver panel, including total bile acid. Brain MRI revealed a pituitary mass, suggesting pituitary-dependent hyperadrenocorticism. The mass was completely resected. The preoperative antithrombotic therapy of rivaroxaban (0.66 mg/kg, PO, once per day) and clopidogrel sulphate (1.66 mg/kg, PO, once per day) was continued postoperatively. Six months after resection of the pituitary mass, the thrombus had disappeared. Further studies are required to prove a causal association between the disappearance of the thrombus and the treatments provided.

Abstract
Objectives Graves' disease (GD) has been highlighted as a possible adverse effect of the respiratory syndrome coronavirus-2 (SARS-CoV-2) vaccine. However, it is unknown if the SARS-CoV-2 vaccine disrupts thyroid autoimmunity. We aimed to present long-term follow-up of thyroid autoimmunity after the SARS-CoV-2 BNT162b2 mRNA vaccine. Methods Serum samples collected from seventy Japanese healthcare workers at baseline, 32 weeks after the second dose (pre-third dose), and 4 weeks after the third dose of the vaccine were analyzed. The time courses of anti-SARS-CoV-2 spike immunoglobulin G (IgG) antibody, thyroid-stimulating hormone receptor antibody (TRAb), and thyroid function were evaluated. Anti-thyroglobulin antibodies (TgAb) and anti-thyroid peroxidase antibodies (TPOAb) were additionally evaluated in thirty-three participants. Results The median age was 50 (IQR, 38-54) years and 69% were female. The median anti-spike IgG antibody titer was 17627 (IQR, 10898-24175) U/mL 4 weeks after the third dose. The mean TRAb was significantly increased from 0.81 (SD, 0.05) IU/L at baseline to 0.97 (SD, 0.30) IU/L 4 weeks after the third dose without functional changes. An increase in TRAb was positively associated with female sex (β = 0.32, P = 0.008) and low basal FT4 (β = -0.29, P = 0.02) and FT3 (β = -0.33, P = 0.004). TgAb was increased by the third dose. Increase in TgAb was associated with history of the thyroid diseases (β = 0.55, P <0.001). Conclusions SARS-CoV-2 BNT162b2 mRNA vaccine can disrupt thyroid autoimmunity. Clinicians should consider the possibility that the SARS-CoV-2 vaccine may disrupt thyroid autoimmunity.

Abstract
Background Immune checkpoint inhibitors (ICIs) are increasingly being used for the treatment of upper gastrointestinal cancers [esophageal cancer and gastric cancer (GC)]. They cause imbalances in immunological tolerance, resulting in immune-related adverse events (irAEs). Although irAEs have been reported to be associated with the efficacy of ICIs in some cancers, the relationship between irAEs and prognosis of upper gastrointestinal cancers remains unknown. This study aimed to investigate the prognostic impact of irAEs in patients with advanced or recurrent upper gastrointestinal cancer treated with nivolumab. Methods We retrospectively divided the patients (n=96) who received nivolumab into two groups: the irAEs group (n=41) and non-irAEs group (n=55), according to the Common Terminology Criteria for Adverse Events ver. 5.0. Results irAEs were significantly associated with good performance status and high serum albumin levels (all P<0.05). The irAEs group had a significantly longer overall survival (OS) than the non-irAEs group [log-rank P=0.003; univariate hazard ratio (HR) =0.36, 95% confidence interval (CI) =0.21-0.65, P<0.01; multivariate HR =0.47, 95% CI =0.26-0.88, P=0.018]. Importantly, in both esophageal cancer and GC, the irAEs group experienced favorable clinical outcomes compared with the non-irAEs group. In the multivariate analysis, male sex (P<0.01), presence of irAEs (P=0.018), and good pretreatment performance status (P<0.01) were independent prognostic factors. Conclusions Among patients with upper gastrointestinal cancer treated with nivolumab, the prognosis of patients who developed irAEs was better than that of patients who did not develop irAEs. Long-term continuation of nivolumab by early detection of irAEs and an appropriate response to irAEs are important.

Abstract
Background Gastric cancer is relatively prone to metastasis, although distant metastasis is rare during the early stage of disease. Here we report a rare case of schwannoma-associated Virchow metastasis of a patient with early-stage gastric cancer. Case presentation A 73-year-old man, diagnosed with early-stage gastric cancer, underwent preoperative scrutiny, and was only suspected to have Virchow metastasis. Owing to atypical metastatic findings, a lymph node biopsy was performed to confirm the diagnosis and to determine the treatment strategy. The pathology results of the biopsy showed a diagnosis of schwannoma, the patient was judged to be surgically resectable, and a laparoscopic gastrectomy was performed to achieve a radical resection. The patient is currently under outpatient observation with no apparent recurrence. Conclusion Systemic chemotherapy is generally administered according to the physician’s clinical judgment, although the results of a lymph node biopsy contribute to a more curative treatment. When nonspecific metastases are found, it is important to make a reliable diagnosis and to select a treatment that achieves a cure.

Abstract
BACKGROUND Large numbers of synchronous colorectal liver metastases are associated with poor prognosis. CASE REPORT A 47-year-old male patient with rectal cancer and unresectable colorectal liver metastases (over 15 cm in diameter and over 30 metastases) was treated with a multidisciplinary treatment including systemic chemotherapy with mFOLFOX6/panitumumab and surgical therapies (colostomy, modified associating liver partition and portal vein ligation for staged hepatectomy together with radiofrequency ablation). For solitary recurrent colorectal liver metastases, percutaneous radiofrequency ablation with chemoembolization and open radiofrequency ablation in combination with the same systemic chemotherapy was performed. Since the diagnosis 3 years ago, he has been leading a good quality of life, free of any tumor or treatment. CONCLUSION For patients with far-advanced but liver-only colorectal liver metastases, surgical therapy, systemic chemotherapy, and interventional treatment can be important for achieving good prognosis.

Abstract
BACKGROUND Bile duct adenomas (BDA) may be precursor lesions of small duct-type, including mass-forming type intrahepatic cholangiocarcinoma (ICC). CASE REPORT A 68-year-old woman was transferred to our facility for the treatment of a liver tumor, possibly metastasized from a pancreatic neuroendocrine tumor. Finally, two liver tumors were resected and histopathologically diagnosed as "BDA" and "ICC with a BDA-like component". In the BDA-like component, the MUC6 positive rate was notably lower and the Ki-67 positive rate was higher than the other BDAs and ICC component, respectively. The doubling time of the tumor volume in BDA was very long but was shortened (1,510 and 719 days). Distinct enlargement of the tumor and appearance of enhancement through diagnostic imaging was useful in diagnosing the transformation from a BDA to an ICC. CONCLUSION An "adenoma-carcinoma sequence" may exist in the transformation process from a BDA to an ICC.

Abstract
BACKGROUND The liver is the digestive organ where metastatic adenocarcinoma of unknown primary site is most often observed. CASE REPORT A 74-year-old man was diagnosed with a growing gallbladder tumor and multiple liver tumors limited to the left lateral sector. Liver tumors were suggested to be primary or secondary adenocarcinoma with no relation to the gallbladder tumor. Also for diagnostic purposes, laparoscopic full-thickness resection of the gallbladder, laparoscopic lateral sectionectomy and lymph node sampling were performed. The final histopathological diagnosis was hyperplastic polyp of the gallbladder and metastatic poorly differentiated adenocarcinoma of the liver. Liver tumors were suspected to originate from the stomach, duodenum, or small intestine; however, the primary sites could not be identified. The patient has been closely followed up without any chemotherapy 3 months after surgery. CONCLUSION Laparoscopic surgery can be strongly recommended for patients with multiple liver tumors of unknown origin concomitant with a gallbladder tumor.

Abstract
BACKGROUND/AIM Cervical oesophageal adenocarcinoma (COA) is extremely rare. We present a case of human epidermal growth factor receptor 2 (HER2)-positive COA that showed repeated recurrences despite multidisciplinary treatments. CASE REPORT A 49-year-old male was diagnosed with clinical stage IVA COA that originated from ectopic gastric mucosa. He initially underwent definitive chemoradiotherapy (CRT) (60.0 Gy/30 fractions, 5-fluorouracil, and cisplatin). Two months after CRT, the right supraclavicular lymph node (LN) reenlarged and salvage lymphadenectomy was performed. Immunohistochemical staining revealed a HER2-positive adenocarcinoma. Four months after lymphadenectomy, multiple metastases in the mediastinal LNs and lungs were detected, and S-1, oxaliplatin and trastuzumab were administered. Four months after chemotherapy, the patient presented with new liver metastasis. Further metastasis was prevented by Nivolumab treatment for four months. CONCLUSION HER2-positive COA may be more aggressive and may require further intensive treatments. This literature review may be helpful in determining treatment strategies for COA.

Abstract
Background
Long-term prognosis after percutaneous coronary intervention (PCI), particularly non-target region stenosis, has not been well improved. Therefore, lifestyle modification should be considered along with medication to prevent the progression of coronary atherosclerosis. Particularly, the promotion of physical activity (PA) is recommended as a core intervention for secondary prevention because of its direct effects on coronary risk factors. However, the factors related to PA after PCI have not been fully investigated.
Purpose
To explore predictors of PA after discharge in patients underwent PCI.
Methods
We conducted a multicenter prospective cohort study. Participants were patients aged <75 years who underwent PCI. The main outcome was PA {step counts (SC) and a time of moderate-to-vigorous physical activity (MVPA)} measured for 7 consecutive days using an accelerometer at 3-month post discharge. We collected demographic data, comorbidities, medical history, laboratory data, and medications from medical record. In addition, severity of chest pain at the onset, physician's explanation regarding long-term prognosis, exercise environments, social support, work, lifestyle except exercise, self-efficacy for walking, difficulty in daily activities and depression were evaluated using questionnaires at discharge and 1-month post-discharge. The study participants were divided into two groups based on the median SC and MVPA at 3-month, and clinical characteristics were compared between the groups using χ2test or Mann Whitney U test. Then, multiple logistic regression analysis adjusted for age, gender, and diagnosis {stable angina or acute coronary syndrome (ACS)} was conducted with 3-month PA as dependent variable. Independent variables were those with a p<0.2 in the univariate analysis. In addition, the area under the curve (AUC) was calculated by receiver operating characteristic analysis to assess predictive accuracy of the regression model.
Results
We enrolled 313 patients [median age: 63 {inter-quartile range (IQR):56–67} years, women: 13.1%, ACS: 16.4%]. The median of SC and MVPA at 3-month were 6902 steps (IQR:5078–9095) and 16.2 min (IQR: 8.6–28.9), respectively. Predictors of SC at 3-month ≥the median were SC at 1-month (odds ratio 1.78, per 1000 steps/day; 95% confidence interval 1.51–2.09), hemoglobin (1.43, per 1g/dl; 1.10–1.86), body mass index (BMI) (0.87, per 1kg/m2; 0.82–0.99), use of β-blocker (0.49, 0.25–0.95), and self-efficacy for walking (1.06, per 1 point; 1.00–1.11). Predictors of MVPA ≥the median were MVPA at 1-month (5.66, per 10 minutes/day; 3.63–8.84), hemoglobin (1.57, per 1g/dl; 1.19–2.06), and BMI (0.85, per 1kg/m2; 0.76–0.94). The AUC of the regression model for SC and MVPA were 0.87 and 0.89, respectively.
Conclusion
PA after PCI could be predicted by modifiable factors with good predictive accuracy. The findings of this study suggest the possibility to develop tailored PA promotion program.

Abstract
BACKGROUND/AIM Recent advances in chemotherapy have increased the possibility of conversion hepatectomy for patients with initially unresectable liver metastases. Although long-term chemotherapy and subsequent extensive hepatectomy are becoming more common, the toxicities of such chemotherapies are unclear. PATIENTS AND METHODS We present a case report of a patient with metastatic colorectal cancer who developed severe encephalopathy with lactic acidosis and hyperammonaemia caused by 5-fluorouracil-based chemotherapy. Administration of vitamin B1 and continuous haemodiafiltration rapidly improved the patient's symptoms. CONCLUSION Intensive treatment of metastatic colorectal cancer patients with 5-fluorouracil can induce rare adverse events.

Abstract
Abstract
Background: Lymphedema in breast cancer is one of the most important complications, and causes symptoms of arm swelling, heaviness and limited movement. Once lymphedema has occurred, it is difficult to cure. Nowadays, treatment with axillary lymph node dissection (ALND) has been decreasing among breast cancer patients as a result of the ACOSOG Z0011, AMAROS and IBCSG 23-01 trials. However, some cases require ALND for ALN metastasis. ALND increases the risk of lymphedema and detracts from quality of life, but the surgical procedure based on anatomical landmarks has not been changed for several decades. The upper borderline for ALND might cause injury to lymph ducts from arms, and incidence and risk factors for lymphedema after ALND are still unclear. Our aim was to identify prevalence and risk factors associated with development of lymphedema after ALND among breast cancer patients.
Methods: This retrospective study was based on data collected from 178 breast cancer patients who underwent ALND in Nagasaki University Hospital, Japan, between 2005 and 2017. Lymphedema was defined as symptomatic arm swelling with >2 cm difference in circumference of the arm compared with that of the contralateral arm. We classified the patients with and without lymphedema, and compared them regarding surgical and pathological findings. Univariate and multivariate analyses were performed to evaluate the risk factors, using the χ2 test, Student's t-test and Cox logistic regression analysis.
Results: Prevalence of lymphedema was 16% (28/178 patients) and mean time interval from surgery to development of lymphedema was 463 days. In univariate analysis, there was a significant difference in postmastectomy radiation therapy (PMRT) (p = 0.02) and the number of patients with >18 dissected ALNs (p = 0.02). Body mass index (p = 0.6), administration of docetaxel (p = 0.2), and smoking (p = 0.07) did not significantly increase lymphedema. In multivariate analysis, PMRT (p = 0.01) and dissection of >18 ALNs (p = 0.001) significantly increased the risk of lymphedema, whereas smoking did not (p = 0.4).
Conclusion: Our study suggested that PMRT and number of dissected ALNs were risk factors for lymphedema. Aggressive and empiric ALND might be associated with axillary lymph duct damage. Therefore, we plan to introduce axillary reverse mapping using indocyanine green to reduce the risk of lymphedema in breast cancer patients who undergo ALND.

Abstract
OBJECTIVES In adults undergoing living donor liver transplantation (LDLT), the transplanted livers are partial grafts, and the portal venous pressure is higher than that observed with whole liver grafts. In patients undergoing LDLT concomitant with splenomegaly, portal venous flow is often diverted to collateral vessels, leading to a high risk of portal vein thrombosis. In such cases, occlusion of the collateral veins is important; however, complete occlusion of all collaterals without blocking the blood flow through the splenic artery causes portal hypertension and liver failure. We aimed to examine the effect of performing a splenectomy concomitant with LDLT to reduce portal vein complications. METHODS Between 1991 and 2017, we performed 170 LDLT operations, including 83 in adults. For this cohort study, adult cases were divided into 2 groups. Group I was those who underwent LDLT without splenectomy (n = 60); Group II was those who underwent LDLT with splenectomy for the reduction of portal hypertension (n = 23). We investigated the incident rates of complications, including blood loss, lethal portal vein thrombosis (intrahepatic thrombosis), acute rejection, and so on. We also investigated the survival rates in both groups. RESULTS The incident rate of lethal portal vein thrombosis in Group II was significantly lower than that observed in Group I (4.4% vs 21.7%, respectively, P = .0363). There were no statistically significant differences observed between the groups with respect to blood loss, survival rates, and other such parameters. CONCLUSION LDLT concomitant with splenectomy might effectively reduce the occurrence of portal vein complications in adults.

Abstract
BACKGROUND The technique of preserving the major tributaries of the middle hepatic vein (MHV) (V5 and V8) until just before graft retrieval is beneficial to minimize congestion time of the graft. However, it remains unclear whether this technique exerts a burden on donors in terms of operative time, blood loss, and postoperative hepatic dysfunction. In this study we investigated adverse effects of the MHV tributaries preserving technique until immediately before graft retrieval on donors' surgical outcomes. METHODS Data from 71 donors who underwent right hepatectomy without MHV for a liver transplantation at our hospital from January 2002 to August 2016 were retrospectively reviewed. Donors were divided into 3 groups as follows: group 1 (n = 12), no MHV tributary reconstruction; group 2 (n = 33), single MHV tributary reconstruction; group 3 (n = 26), 2 or 3 MHV tributaries reconstruction. Donor operation time, blood loss, proportion of the remnant liver, maximum postoperative total bilirubin, aspartate aminotransferase, alanine transaminase, minimum platelets, prothrombin time, albumin level, number of days in hospital from surgery to discharge, and surgical complications were compared. RESULTS Compared with groups 2 and 3, group 1 exhibited shorter average operational time and less average blood loss, but the difference was not significant. Comparisons of all other factors indicated no significant differences. CONCLUSION The technique of preserving the major tributaries of the MHV until just immediately before graft retrieval does not appear to impose an apparent burden on donors.

Abstract
In the past few years, several types of artificial transcriptional activator, based on CRISPR-Cas9, have been developed and refined. Of these, in synergistic activation mediator and SunTag systems, the effector proteins, expressed in trans, can be recruited to the target sites via the MS2 RNA-binding system and GCN4-scFv antibody system, respectively. Here, we report a strong transcriptional activation system achieved by fusing GCN4 repeat to MS2 coat protein to accumulate numbers of activators, fused to scFv antibodies. By targeting the CDH1 gene, we show that our novel system, named “TREE,” results in a greater effect of activating exogenous reporter and endogenous gene. Moreover, by targeting another gene, RANKL, we consistently show the superiority of the TREE system with fewer single-guide RNAs compared to conventional systems. Our TREE system is a promising tool for transcriptional activation and can potentially contribute to other dCas9-mediated technologies such as epigenome editing and chromosome visualization.

Abstract
Alzheimer's disease is a progressive neurodegenerative disease for which there is no cure and only a few treatments providing little relief. Increased oxidative stress that is associated with aging is strongly implicated in the pathogenesis and progression of Alzheimer's disease. Studies have shown that levels of the endogenous antioxidant glutathione decline at an early stage of Alzheimer's disease with decreased levels correlating with worse cognitive functions. N-acetylcysteine, a drug also widely available as a dietary supplement, is a precursor of L-cysteine, which in turn is a component of glutathione. Because cysteine availability is a limiting factor for glutathione synthesis, treatment with N-acetylcysteine may increase glutathione levels and thereby counter oxidative stress, promote redox -regulated cell signaling, and improve immune responses. In this review, we evaluate the existing literature and the potential of N-acetylcysteine in promoting cognitive health and alleviating cognitive decline associated with dementia. Discussion will also include possible mechanisms of action of N-acetylcysteine, its effects on aging biology, and safety of long-term use. Based on the available literature, a nutraceutical formulation containing N-acetylcysteine among other compounds has shown some pro-cognitive benefits in Alzheimer's patients and older adults, but the evidence for N-acetylcysteine alone is less robust. Although N-acetylcysteine crosses the blood-brain-barrier, low bioavailability is an obstacle. One promising avenue of research may be to explore derivatives of N-acetylcysteine such as N-acetylcysteine amide, which has been reported in preclinical studies to have higher permeability through cellular and mitochondrial membranes with increased central nervous system bioavailability compared to N-acetylcysteine.

Abstract
BACKGROUND AND OBJECTIVE Attachment loss of the junctional epithelium and alveolar bone destruction are signs of periodontitis, which is mainly caused by an inflammatory response to dental plaque. Glycyrrhetinic acid (GA), a component of the licorice herb, has been shown to have important anti-inflammatory activities; however, there are no previous reports on the ability of its inhibitory effects to prevent periodontal diseases. Hence, in this study, using our experimental periodontitis model, we attempted to evaluate whether GA had an effect on the prevention of attachment loss and alveolar bone loss. MATERIAL AND METHODS Rats were intraperitoneally immunized with Escherichia coli lipopolysaccharide (LPS). The LPS group (n = 5) received 3 topical applications of 50 μg/μL of LPS followed by one application of the vehicle (propylene glycol:ethyl alcohol:phosphate-buffered saline [PBS] = 8:1:1) into the gingival sulcus. This protocol was repeated twice per day for 10 days. The low (n = 5) and high (n = 5) groups received topical application of LPS and 0.03% or 0.3% GA, respectively. The control group received topical application of PBS and vehicle. The rats were killed on the 10th day. Attachment loss, alveolar bone level and inflammatory cell infiltration were investigated histometrically. The formation of immune complexes and infiltration of LPS were evaluated immunohistologically. RESULTS Attachment loss, formation of immune complexes and infiltration of inflammatory cells were increased in the LPS group compared with the control group, and were completely inhibited in the low and high groups compared with the LPS group. The LPS group showed greater alveolar bone destruction compared with the control group and GA-treated groups. In addition, invasion of LPS was detected in the LPS group, was absent in the control group and was weaker in the GA-treated groups than in the LPS group. CONCLUSION In the present study, we showed that GA inhibits periodontal destruction in the rat experimental periodontitis model.

Abstract
Removal of bacteria by handwashing with ozonated water was evaluated using the ASTM E1174 standard test method. Thirty healthy volunteers were assigned randomly to three groups: ozonated water, antimicrobial soap and water, and non-antimicrobial soap and water. A 3 log10 cfu reduction was achieved by washing hands with ozonated water or antimicrobial soap and water. However, ozonated water was not significantly superior to non-antimicrobial soap and water. Ozonated water may remove bacteria from the hands to at least a similar extent as that by non-antimicrobial soap and water in the absence of visible dirt or body fluid contamination.

Abstract
BACKGROUND/PURPOSE The relationships between the skin components and these mechanical roles are still unclear. To clarify these relationships, we investigated spatial mapping of the mechanical behavior of cultured skin equivalents (SEs) using optical coherence tomography (OCT)-based straingraphy. METHODS We built a strain relaxation test system combined with OCT and developed an algorithm that could visualize a time-dependent strain distribution, named dynamic-optical coherence straingraphy (D-OCSA). Using this system, we analyzed how the spatial mechanical changes in the SEs depended on the culture duration. For quantitative analysis of viscoelastic behavior, we defined a relaxation attenuation coefficient of strain rate, which indicates the ratio of viscosity and elasticity in the Klevin-Voight model. RESULTS By culturing for 4 days in comparison to culturing for 1 day, the strain relaxation attenuation coefficient of the whole skin, especially at the region of the dermal-epidermal junction (DEJ), significantly increased in the negative direction. In tissue slices taken for microscopy, several cracks were observed in the SEs cultured for 4 days. CONCLUSION This study is the first to provide quantified evidence that the DEJ is a dynamically specialized region. An OCT-based straingraphy system (D-OCSA) would be beneficial for evaluating the quality of SEs, as well as functional analysis of their mechanics.

Abstract
OBJECTIVE Graft injuries sometimes occur and may cause complications such as the leakage of pancreatic secretions, which is often lethal. We report our experience of a case of successful simultaneous pancreas-kidney transplantation using injured pancreas graft. PATIENTS AND METHODS The recipient was a 57-year-old woman with type 1 diabetes mellitus, and the donor was a 30-year-old man with a brain injury. In the donation, the pancreas parenchyma, splenic artery, and gastroduodenal artery were injured iatrogenically. We therefore reconstructed these arteries using vessel grafts and then performed simultaneous pancreas-kidney transplantation. RESULTS Five days after transplantation, we noted a high titer of amylase in the ascites; therefore, we performed an urgent laparotomy. The origin of the amylase was the injured pancreatic parenchyma, and continued washing and drainage were carried out. We reconstructed the duodenojejunostomy using the Roux-en-Y technique to separate the passage of food from the pancreas graft to prevent injury to other organs due to exposure to pancreatic secretions. Thereafter, we inserted a decompression tube into the anastomosis thorough the blind end of the jejunum. Finally, we inserted 3 drainage tubes for lavage. Following this procedure, the patient recovered gradually and no longer required hemodialysis and insulin therapy. She was discharged from our hospital 56 days after transplantation. CONCLUSION The restoration of the injured graft was possible by management of pancreatic secretions and use of the donor's vessel grafts. Shortage of donors is a problem throughout the world; thus, it is important to use injured grafts for transplantation if possible.

Abstract
BACKGROUND AND OBJECTIVE Dental calculus is a mineralized deposit attached to the tooth surface. We have shown that cellular uptake of dental calculus triggers nucleotide-binding oligomerization domain-like receptor family pyrin domain-containing 3 (NLRP3) inflammasome activation, leading to the processing of the interleukin-1β precursor into its mature form in mouse and human phagocytes. The activation of the NLRP3 inflammasome also induced a lytic form of programmed cell death, pyroptosis, in these cells. However, the effects of dental calculus on other cell types in periodontal tissue have not been investigated. The aim of this study was to determine whether dental calculus can induce cell death in oral epithelial cells. MATERIAL AND METHODS HSC-2 human oral squamous carcinoma cells, HOMK107 human primary oral epithelial cells and immortalized mouse macrophages were exposed to dental calculus or 1 of its components, hydroxyapatite crystals. For inhibition assays, the cells were exposed to dental calculus in the presence or absence of cytochalasin D (endocytosis inhibitor), z-YVAD-fmk (caspase-1 inhibitor) or glyburide (NLRP3 inflammasome inhibitor). Cytotoxicity was determined by measuring lactate dehydrogenase (LDH) release and staining with propidium iodide. Tumor necrosis factor-α production was quantified by enzyme-linked immunosorbent assay. Oral epithelial barrier function was examined by permeability assay. RESULTS Dental calculus induced cell death in HSC-2 cells, as judged by LDH release and propidium iodide staining. Dental calculus also induced LDH release from HOMK107 cells. Following heat treatment, dental calculus lost its capacity to induce tumor necrosis factor-α in mouse macrophages, but could induce LDH release in HSC-2 cells, indicating a major role of inorganic components in cell death. Hydroxyapatite crystals also induced cell death in both HSC-2 and HOMK107 cells, as judged by LDH release, indicating the capacity of crystal particles to induce cell death. Cell death induced by dental calculus was significantly inhibited by cytochalasin D, z-YVAD-fmk and glyburide, indicating NLRP3 inflammasome involvement. In permeability assays, dental calculus attenuated the barrier function of HSC-2 cell monolayers. CONCLUSION Dental calculus induces pyroptotic cell death in human oral epithelial cells and the crystalline structure plays a major role in this process. Oral epithelial cell death induced by dental calculus might be important for the etiology of periodontitis.

Abstract
BACKGROUND The diagnosis of the progression of periodontitis presently depends on the use of clinical symptoms (such as attachment loss) and radiographic imaging. The aim of the multicenter study described here was to evaluate the diagnostic use of the bacterial content of subgingival plaque recovered from the deepest pockets in assessing disease progression in chronic periodontitis patients. METHODS This study consisted of a 24-month investigation of a total of 163 patients with chronic periodontitis who received trimonthly follow-up care. Subgingival plaque from the deepest pockets was recovered and assessed for bacterial content of Porphyromonas gingivalis, Prevotella intermedia, and Aggregatibacter actinomycetemcomitans using the modified Invader PLUS assay. The corresponding serum IgG titers were measured using ELISA. Changes in clinical parameters were evaluated over the course of 24 months. The sensitivity, specificity, and prediction values were calculated and used to determine cutoff points for prediction of the progression of chronic periodontitis. RESULTS Of the 124 individuals who completed the 24-month monitoring phase, 62 exhibited progression of periodontitis, whereas 62 demonstrated stable disease. The P. gingivalis counts of subgingival plaque from the deepest pockets was significantly associated with the progression of periodontitis (p < 0.001, positive predictive value = 0.708). CONCLUSIONS The P. gingivalis counts of subgingival plaque from the deepest pockets may be associated with the progression of periodontitis.

Abstract
OBJECTIVES In living donor liver transplantation (LDLT), the recipient bile duct is thin and short. Bile duct complications often occur in LDLT, with persistent long-term adverse effects. Recently, we began to perform microsurgical reconstruction of the bile duct. The purpose of this study was to investigate the relationship between bile duct reconstruction methods and complications in LDLT. METHODS From 1991 to 2014, we performed 161 LDLTs (pediatric:adult = 90:71; left lobe:right lobe = 95:66). In this study, we retrospectively investigated the initial bile duct complications in LDLT and performed univariate and multivariate analyses to identify the independent risk factors for complications. RESULTS The most frequent complication was biliary stricture (9.9%), followed by biliary leakage (6.8%). On univariate and multiple logistic regression analysis, the independent risk factors for biliary stricture were bile leakage (P = .0103) and recurrent cholangitis (P = .0077). However, there were no risk factors for biliary leakage on univariate analysis in our study. The reconstruction methods (hepaticojejunostomy or duct-to-duct anastomosis) and reconstruction technique (with or without microsurgery) were not risk factors for biliary stricture and leakage. CONCLUSION In this study, the most frequent complication of LDLT was biliary stricture. The independent risk factors for biliary stricture were biliary leakage and recurrent cholangitis. Duct-to-duct anastomosis and microsurgical reconstruction of the bile duct were not risk factors for biliary stricture and leakage.

Abstract
BACKGROUND Post-transplant donor-specific anti-HLA antibodies (DSA) reportedly have detrimental effects on the outcomes of organ transplantation. However, the prevalence of post-transplant DSA in the long term after pediatric liver transplantation remains unclear, and the significance of post-transplant DSA is unknown. The aim of this cross-sectional study was to determine the prevalence of and characteristics of patients with post-transplant DSA. MATERIALS AND METHODS Of the 84 pediatric liver transplant recipients who were followed up in the outpatient department of our institution, 34 patients with available HLA typing data were included after they or their parent(s) provided informed consent for DSA evaluations. Luminex single-antigen bead assays were performed, and a mean fluorescence intensity of ≥1000 was used as the cut-off for a positive reaction. RESULTS No class I DSA were detected, whereas class II DSA were detected in 11 patients (32%). There were no differences in age at transplantation, immunosuppressive drugs, or follow-up period between the DSA-positive and DSA-negative patients. The rate of positive pre-transplant complement-dependent cytotoxicity crossmatch was higher with class II DSA than without, although the difference was not statistically significant. CONCLUSIONS The utility of screening for class I DSA was insignificant in the long-term follow-up of pediatric liver transplant recipients. The prevalence of class II DSA was relatively high; therefore, screening for class II DSA might be justified, although a follow-up survey of the association between post-transplant class II DSA and the long-term clinical course needs to be conducted.

Abstract
The purpose of this study was to investigate the expression of bone morphogenetic protein 4 (BMP4) and its receptors, bone morphogenetic protein receptor I (BMPRI) and BMPRII, in the pituitary gland of healthy adult dogs and in those with ACTH-secreting pituitary adenoma. Quantitative polymerase chain reaction analysis showed that the BMP4 messenger RNA expression level in the ACTH-secreting pituitary adenoma samples was significantly lower than that in the normal pituitary gland samples (P = 0.03). However, there were no statistically significant differences between samples with respect to the messenger RNA expression levels of the receptors BMPRIA, BMPRIB, and BMPRII. Double-immunofluorescence analysis of the normal canine pituitary showed that BMP4 was localized in the thyrotroph (51.3 ± 7.3%) and not the corticotroph cells. By contrast, BMPRII was widely expressed in the thyrotroph (19.9 ± 5.2%) and somatotroph cells (94.7 ± 3.6%) but not in the corticotroph cells (P < 0.001, thyrotroph cells vs somatotroph cells). Similarly, in ACTH-secreting pituitary adenoma, BMP4 and BMPRII were not expressed in the corticotroph cells. Moreover, the percentage of BMP4-positive cells was also significantly reduced in the thyrotroph cells of the surrounding normal pituitary tissue obtained from the resected ACTH-secreting pituitary adenoma (8.3 ± 7.9%) compared with that in normal canine pituitary (P < 0.001). BMP4 has been reported to be expressed in corticotroph cells in the human pituitary gland. Therefore, the results of this study reveal a difference in the cellular pattern of BMP4-positive staining in the pituitary gland between humans and dogs and further revealed the pattern of BMPRII-positive staining in the dog pituitary gland. These species-specific differences regarding BMP4 should be considered when using dogs as an animal model for Cushing's disease.

Abstract
OBJECTIVE Computer simulation studies of skin models, which indicate skin compression in the same manner as facial expressions, have suggested that stratum corneum could control skin-folding patterns, which may play an essential role in wrinkle formation. However, it is not clear to what extent the mechanics of stratum corneum influence wrinkle formation in vivo. The aim of this study was to verify that stratum corneum could control strain distribution during facial expressions, which in turn leads to wrinkle formation. METHODS In experiments in vivo, volunteers were instructed to smile under 10% or 80% relative humidity (dry or humid conditions, respectively). Skin movement around their eye corners during smiling was captured by a high-speed video camera. Particle-tracking velocimetry was applied to video recordings to analyse skin strain distribution. Also, wrinkle volumes before or after smiling were measured using replicas. RESULTS With smiling under dry conditions, high strain was localized to form crease-shaped wrinkles whereas, under humid conditions, localized strain was dispersed. Furthermore, increased wrinkle volume after smiling was promoted under dry conditions. CONCLUSION Because exposure to dry or humid conditions in the short term could affect only stratum corneum mechanics, the present results indicated that stratum corneum could be considered to be responsible for localized strain during facial expressions. This strain is followed by residual wrinkle formation. Accumulation of residual wrinkles will produce permanent wrinkles in the long term. Improving the mechanics of stratum corneum might be an effective approach in wrinkle formation prevention.

Abstract
Muscle lesions and decreased numbers of peripheral nerve branches have been reported in the soft palates of dogs presenting with brachycephalic airway obstruction syndrome (BAOS). Myosin adenosine triphosphatase staining was employed to investigate whether muscle lesions in the elongated soft palate (ESP) of dogs with BAOS reflect the presence of denervation. Soft palates were collected from nine brachycephalic dogs during surgical intervention for BAOS and from five healthy beagle dogs as controls. In the control soft palates, myofibres with relatively uniform diameters and a random mosaic pattern of type I and II myofibres were observed in the palatinus muscle (PM), while almost all of the myofibres in the levator veli palatini muscle (LVPM) were of type II. In the ESPs, small group atrophy, large group atrophy and angular-shaped atrophy were observed in myofibres of the PM and rarely in the LVPM. Fibre type grouping and an increase in type IIC myofibres were found only in the PM. Morphometric analysis of ESPs revealed a significant increase in the number of type I and II myofibres in the PM showing atrophy or hypertrophy compared with controls. A significant increase in atrophic type II myofibres was found in the LVPM of affected dogs. Myopathy consistent with denervation was observed in the PM, but rarely in the LVPM, of ESP specimens. The results suggest that the myopathy seen in dogs with ESP may partly reflect atrophy of myofibres resulting from damage to peripheral nerve branches, with subsequent reinnervation of myofibres.

Abstract
Transvenous embolization of venous compartments within the venous sinus wall was the method initially attempted for closing dural arteriovenous fistulas in 15 patients (22 sinuses). The venous channel, separate from the sinus lumen and located in the venous sinus wall, could be embolized in 6 lesions (3 patients), including 3 superior sagittal sinus fistulas, 2 transverse sinus fistulas, and 1 straight sinus fistula. This technique resulted in closure of the fistulas and preservation of sinus patency as well as immediate improvement of clinical symptoms. The embolizable venous compartment of the fistula within the venous sinus wall could be detected by preoperative angiography, magnetic resonance imaging, and intraoperative venography. This unique drainage of dural arteriovenous fistulas may develop concurrently with more obvious portions of the fistula. Transvenous embolization of these venous compartments can close the fistulas and normalize impaired sinus function.

Abstract
We report our experience with endovascular embolization using liquid coils. Twenty-two transarterial embolization procedures were performed with these coils in 20 patients with cerebrospinal vascular or neoplastic lesions. The coils were delivered into the target vessels under fluoroscopic monitoring through a microcatheter by manual injection and flushing with saline. Subsequent surgical resections of embolized lesions were performed in 14 cases, and radiosurgery for two. Complete obliteration of the target vessels were accomplished in all cases without complications. Passage through the microcatheter and delivery of the coil was smooth. Proximal protrusion of the coil occurred during the procedure, and a combination of other embolic materials was necessary to completely occlude large vessels in 9 cases. The embolized lesions were easily resected in the following neurosurgery. Liquid coils were safe and effective as an embolic material in use prior to surgery or radiosurgery.

Abstract
BACKGROUND In this study, we demonstrated our new device for open donor liver surgery with left-sided heptectomy by use of the real-time moving windows (RTMW) method with 8-cm transverse skin incision for living donors from the viewpoints of cosmetic, economic, and safety procedures. METHODS After the upper abdominal 8-cm transverse skin incision was made, the subcutaneous area was exfoliated and the reverse T-shaped-abdominal incision was made, as in open surgery. After that, the 2 Kent hooks for the upper region and the 2 surgical arms for the lower region were placed. The operative fields of hepatic vein, hepatic hilus, and common hepatic artery were explored, respectively, by use of the RTMW method with the use of the 4 surgical hooks. Hepatic parenchymal dissection was carried out with the use of CUSA and laparosonic coagulating shears. Manipulations of 3 hepatic vessels and the hepatic duct were done by the usual procedure of open surgery. RESULTS This operative procedure could be performed without laparoscopic techniques. The operative time was 7 hours, without blood transfusion. The operative course was uneventful, and the patient was discharged on postoperative day 11. CONCLUSIONS Our RTMW method for donor left-sided hepatectomy is considered to be a useful operative procedure from the viewpoints of donor safety, cosmetic advantage, and cost performance.

Abstract
OBJECT Pancreas transplantation has the highest surgical complication rate of all routinely performed organ transplantation procedures. The complications are not only caused by the pancreas itself but also occur due to issues with the transplant recipient. We report the case of a patient who experienced massive gastrointestinal bleeding after simultaneous pancreas-kidney transplantation (SPK), which was stopped successfully using somatostatin analog. PATIENTS AND METHODS The patient was a 45-year-old woman with diabetes mellitus type 1 who underwent SPK with enteric drainage. She had melena 5 days after SPK. RESULTS At first, we suspected that the melena was caused by the transplanted duodenum because of rejection and ischemic changes. The patient experienced severe bleeding 9 days after SPK. We quickly performed open surgery and inserted an endoscope from the recipient's ileum to investigate the transplanted duodenum. However, no bleeding source was found, including in the transplanted duodenum and the recipient's ileum end. We determined that the bleeding source was the recipient's ascending colon. We attempted to perform endovascular treatment but could not detect the source of the bleeding; therefore, we used somatostatin analog to let the blood vessels shrink and reduce pancreatic output. Thereafter, the function of the transplanted pancreas and kidney gradually recovered, and the recipient was discharged 154 days after SPK. CONCLUSION Gastrointestinal bleeding is a lethal complication and has several different causes, such as mucosal rejection, ischemic changes, and exocrine output of the pancreas graft. Somatostatin analog is one of the most acceptable treatments for patients who have gastrointestinal bleeding after SPK.

Abstract
OBJECTIVES The objectives of this study were to establish a magnetic resonance imaging-based classification system for canine hyperadrenocorticism according to pituitary gland extension, determine indications for trans-sphenoidal hypophysectomy, and clarify the prognosis for each disease grade. METHODS A 5-point classification system (Grades 1 to 5) was developed based on tumour extension in dorsal and cranio-caudal directions. Cases were then classified as Type A: no arterial circle of Willis or cavernous sinus involvement and Type B: cases in which these blood vessels were involved. RESULTS Medical records and magnetic resonance imaging data of 37 cases with hyperadrenocorticism were reviewed. Thirty-three cases underwent surgery; 4 Grade 5 cases did not have appropriate indications for surgery, and other therapies were used. Complete resection was achieved for 3, 3, 22 and 1 Grade 1A, 2A, 3A and 3B cases, respectively. Resection was incomplete in 1, 1 and 2 Grade 3A, 3B and 4B cases, respectively. Remission was achieved in 29 cases. Recurrence occurred in 4 cases, all of which were classified as Grade 3. CLINICAL SIGNIFICANCE Dogs with Type A, Grade 1 to 3 hyperadrenocorticism had a good prognosis following trans-sphenoidal hypophysectomy. Grade 3B, 4 and 5 cases may not be suitable for this surgery.

Abstract
BACKGROUND AND OBJECTIVE The barrier function of long junctional epithelium is thought to be important after periodontal initial therapy and periodontal surgery. Although the difference between long junctional epithelium and normal junctional epithelium regarding their resistance to destruction of periodontal tissue has been investigated, the mechanism still remains unclear. Using our rat experimental periodontitis model in which loss of attachment and resorption of alveolar bone is induced by the formation of immune complexes, we investigated the resistance of periodontal tissue containing long junctional epithelium and normal junctional epithelium to destruction. MATERIAL AND METHODS Rats were divided into four groups. In the immunized long junctional epithelium (I-LJE) group, rats were immunized with lipopolysaccharide (LPS), and curettage and root planing procedures were performed on the palatal gingiva of the maxillary first molars to obtain reattachment by long junctional epithelium. In the immunized normal junctional epithelium (I-JE) group, rats were immunized without curettage and root planing procedures. In the nonimmunized long junctional epithelium (nI-LJE) group, rats were not immunized but curettage and root-planing procedures were performed. In the control group, neither immunization nor curettage and root-planing was performed. In all rats, periodontal inflammation was induced by topical application of LPS into the palatal gingival sulcus of maxillary first molars. The rats were killed at baseline and after the third and fifth applications of LPS. Attachment loss and the number of inflammatory cells and osteoclasts in the four groups were compared histopathologically and histometrically. RESULTS After the third application of LPS in the I-LJE group, attachment loss showed a greater increase than in control and nI-LJE groups, and inflammatory cell infiltration and osteoclasts were increased more than in the other groups. After the fifth application of LPS, attachment loss was greater and there was a higher degree of inflammatory cell infiltration in nI-LJE and I-LJE groups than in control and I-JE groups. CONCLUSION Our findings suggest that the destruction of periodontal tissue is increased in tissue containing long junctional epithelium compared with normal junctional epithelium and that the immunized condition accelerates the destruction by forming immune complexes.

Abstract
BACKGROUND AND OBJECTIVE A diagnosis of periodontitis progression is presently limited to clinical parameters such as attachment loss and radiographic imaging. The aim of this multicenter study was to monitor disease progression in patients with chronic periodontitis during a 24-mo follow-up program and to evaluate the amount of bacteria in saliva and corresponding IgG titers in serum for determining the diagnostic usefulness of each in indicating disease progression and stability. MATERIAL AND METHODS A total of 163 patients with chronic periodontitis who received trimonthly follow-up care were observed for 24 mo. The clinical parameters and salivary content of Porphyromonas gingivalis, Prevotella intermedia and Aggregatibacter actinomycetemcomitans were assessed using the modified Invader PLUS assay, and the corresponding serum IgG titers were measured using ELISA. The changes through 24 mo were analyzed using cut-off values calculated for each factor. One-way ANOVA or Fisher's exact test was used to perform between-group comparison for the data collected. Diagnostic values were calculated using Fisher's exact test. RESULTS Of the 124 individuals who completed the 24-mo monitoring phase, 62 exhibited periodontitis progression, whereas 62 demonstrated stable disease. Seven patients withdrew because of acute periodontal abscess. The ratio of P. gingivalis to total bacteria and the combination of P. gingivalis counts and IgG titers against P. gingivalis were significantly related to the progression of periodontitis. The combination of P. gingivalis ratio and P. gingivalis IgG titers was significantly associated with the progression of periodontitis (p = 0.001, sensitivity = 0.339, specificity = 0.790). CONCLUSIONS It is suggested that the combination of P. gingivalis ratio in saliva and serum IgG titers against P. gingivalis may be associated with the progression of periodontitis.
