Abstract
BACKGROUND Poor oral health is an independent risk factor for upper-aerodigestive tract cancers, including esophageal cancer. Several studies have investigated short-term outcomes after esophagectomy and the impact of periodontal disease, but few have examined the impact of periodontal disease on long-term outcomes. The purpose of this study was to investigate the rate of periodontitis among esophagectomy patients and the prognostic value of periodontitis and its effect on prognosis after esophagectomy. METHODS A total of 508 patients who underwent esophagectomy received oral health care from a dentist before cancer treatment at Akita University Hospital between January 2009 and December 2021. We assessed the presence and severity of the patients' periodontitis and divided them into no-periodontitis, mild periodontitis, severe periodontitis and edentulous jaw groups. We then assessed 10-year overall survival (OS) and disease-specific survival (DSS) and determined whether periodontitis was an independent prognostic factor affecting OS and DSS. RESULTS We found that 101 (19.9%) patients had no periodontitis, 207 (40.8%) had mild periodontitis, 176 (34.6%) had severe periodontitis requiring tooth extraction, and 24 (4.7%) had edentulous jaw. Both OS and DSS were significantly poorer in the periodontitis than no-periodontitis group (p < 0.001). In detail, the edentulous jaw group had the poorest prognosis (p < 0.001). Multivariate analysis showed that periodontitis was an independent risk factor affecting OS and DSS. CONCLUSION Esophageal cancer patients had a high prevalence of periodontitis. Moreover, the presence of periodontitis and severity of periodontitis are independent risk factors contributing to a poorer prognosis after esophagectomy.

Abstract
OBJECTIVE We examined whether preoperative inspiratory muscle weakness (IMW) is a risk factor for postoperative pulmonary complications (PPCs) in patients with esophageal cancer who underwent subtotal esophagectomy. METHODS This single-center retrospective cohort study enrolled patients with esophageal cancer who underwent a scheduled subtotal esophagectomy between June 2020 and May 2022. Maximal inspiratory pressure (MIP) was measured as inspiratory muscle strength using a respiratory dynamometer, and we defined IMW as MIP < 80% of the predicted value. Our primary outcome comprised overall PPCs. We investigated the relationship between IMW and PPCs using the Bayesian logistic regression model. RESULTS After exclusion, 72 patients were included in this study. IMW was identified in 26 patients (36%), and PPCs developed in 28 patients (39%). Among patients with IMW, 15 (58%) developed PPCs. Preoperative IMW was associated with PPCs (mean odds ratio [OR]: 3.58; 95% credible interval [95% CrI]: 1.29, 9.73) in the unweighted model. A similar association was observed in the weighted model adjusted for preoperative and intraoperative contributing factors (mean OR: 4.15; 95% CrI: 2.04, 8.45). CONCLUSIONS Preoperative IMW was associated with PPCs in patients with esophageal cancer who underwent subtotal esophagectomy. This association remained after adjusting for preoperative and intraoperative contributing factors.

Abstract
Aim Because the optimal treatment strategy for borderline resectable (cT3br) thoracic esophageal cancer patients remains unclear, it is of great interest whether preoperative neoadjuvant therapy for cT3br could achieve results comparable to those seen with resectable T3 cancer (cT3r). We speculated that preoperative neoadjuvant chemoradiotherapy (NACRT) would be particularly effective in cT3br thoracic esophageal cancer patients and compared to cT3br and cT3r. Methods Of 186 cT3 thoracic esophageal cancer patients treated with intended NACRT, 162 received radical esophagectomy. More than 97% were squamous cell carcinomas. Patients were partitioned into two groups according to whether invasion of adjacent organs was suspected (cT3br and cT3r). Treatment outcomes and survival were analyzed. Results Sixty-eight patients (36.6%) were classified as cT3br and 118 (63.4%) as cT3r. The cT3br group had significantly more tumors in the upper and middle mediastinum (p < 0.0001) and more cases with cM1 (lymph node) (p = 0.0104) than the cT3r group. In addition, the cT3br patients receiving esophagectomy exhibited a significantly lower pathological complete response rate than the cT3r patients (p = 0.0374). However, the R0 resection rate did not differ between the cT3br and cT3r patients (p = 0.0978), and the two groups treated with intended NACRT had similar 5-year overall (OS) and disease-specific survival (DSS) (p = 0.3831 and p = 0.9020). In addition, the incidence and patterns of recurrence did not differ between the cT3br and cT3r patients receiving esophagectomy (p = 0.8109 and p = 0.3128). Conclusions Preoperative neoadjuvant chemoradiotherapy appears to be a promising treatment for patients with borderline resectable thoracic esophageal squamous cell carcinoma.

Abstract
Tumor-derived G-CSF is a well-known factor to aggravate disease progression in various types of cancers. In this study, we investigated a role of G-CSF in squamous cell carcinoma (SCC). High expression of G-CSF in the tumor tissues of esophageal SCC (ESCC) patients correlated with poor prognosis. Murine SCC NR-S1M cells produce considerable amount of G-CSF, which expression is correlated with its metastatic potentials. Deletion of G-CSF in NR-S1M cells mitigated tumor growth and metastasis to lymph node and lung of subcutaneous NR-S1M tumors in the mice. Mechanistically, G-CSF enhanced cell proliferation in autocrine manner in vitro, whereas in NR-S1M tumor-bearing mice, accumulation of plasma G-CSF was associated with expansion of peripheral neutrophils, which led to a decreased proportion of CD8+ T cells. Antibody depletion of neutrophils restored the number of CD8+ T cells and modestly suppressed tumor outgrowth, albeit no changes in distant metastasis. We propose that G-CSF produced by NR-S1M cells facilitates tumor progression in mice through bi-functional effects to promote neutrophil recruitment and tumor cell proliferation, which may render poor prognosis to the ESCC patients with high G-CSF expression.

Abstract
Most so-called "beneficial bacteria" in gut microbiota are Gram-positive, and TLR6 recognizes the peptidoglycan (PGN) present in their cell walls. We hypothesized that a high TLR6 expression status predicts a more favorable prognosis after esophagectomy. We used an ESCC tissue microarray (TMA) to examine TLR6 expression status in ESCC patients and to determine whether TLR6 expression status correlates with prognosis after curative esophagectomy. We also examined whether PGN influences the cell proliferation activity of ESCC lines. Clinical ESCC samples from 177 patients tested for the expression of TLR6 were categorized as 3+ (n = 17), 2+ (n = 48), 1+ (n = 68), or 0 (n = 44). High TLR6 expression (3+ and 2+) correlated with significantly more favorable 5-year overall survival (OS) and disease-specific survival (DSS) after esophagectomy than a lower TLR6 expression (1+ and 0). Univariate and multivariate analyses showed that TLR6 expression status is an independent prognostic factor that affects 5-year OS. PGN significantly inhibited the cell proliferation activity of ESCC lines. This is the first study to show that high TLR6 expression status predicts a more favorable prognosis in locally advanced thoracic ESCC patients after curative esophagectomy. PGN released from "beneficial bacteria" seems to have potential to inhibit the cell proliferation activity of ESCC.

Abstract
Metastasis predicts poor prognosis in cancer patients. It has been recognized that specific tumor microenvironment defines cancer cell metastasis, whereas the underlying mechanisms remain elusive. Here we show that Galectin-7 is a crucial mediator of metastasis associated with immunosuppression. In a syngeneic mouse squamous cell carcinoma (SCC) model of NR-S1M cells, we isolated metastasized NR-S1M cells from lymph nodes in tumor-bearing mice and established metastatic NR-S1M cells in in vitro culture. RNA-seq analysis revealed that interferon gene signature was markedly downregulated in metastatic NR-S1M cells compared with parental cells, and in vivo NR-S1M tumors heterogeneously developed focal immunosuppressive areas featured by deficiency of anti-tumor immune cells. Spatial transcriptome analysis (Visium) for the NR-S1M tumors revealed that various pro-metastatic genes were significantly upregulated in immunosuppressive areas when compared to immunocompetent areas. Notably, Galectin-7 was identified as a novel metastasis-driving factor. Galectin-7 expression was induced during tumorigenesis particularly in the microenvironment of immunosuppression, and extracellularly released at later stage of tumor progression. Deletion of Galectin-7 in NR-S1M cells significantly suppressed lymph node and lung metastasis without affecting primary tumor growth. Therefore, Galectin-7 is a crucial mediator of tumor metastasis of SCC, which is educated in the immune-suppressed tumor areas, and may be a potential target of cancer immunotherapy.

Abstract
The advantages of salvage esophagectomy through robotic-assisted surgery for patients with clinically diagnosed tumor invasion of adjacent vital organs (cT4b) or patients with scar tissue from definitive chemoradiotherapy (dCRT) are still only rarely reported. A man in his 60s with middle thoracic esophageal cancer (cT4b [left main bronchus] N1 M0 cStage IIIC) received dCRT (60 Gy). After the chemoradiotherapy, upper gastrointestinal endoscopy revealed a residual primary tumor, and we performed robotic-assisted thoracoscopic subtotal esophagectomy and gastric tube reconstruction via a retrosternal route with three-field lymphadenectomy. Although it was difficult to dissect the tumor from adjacent organs, especially the left main bronchus and left inferior pulmonary vein, due to loss of the dissecting layer and scarring, R0 surgery was achieved. With robot-assisted thoracoscopic surgery, the high-magnification, high-resolution, and three-dimensional images; the stable surgical field with full countertraction made with the robotic arm forceps, which were readily adjusted; and the stable motion of the robotic arm without physiological tremor are considerable advantages for salvage esophagectomy for cT4b tumors. It goes without saying that sufficient experience with robot-assisted surgery and sufficient understanding and surgical skill in esophageal cancer surgery under suitable surgical indications and timing are required to make use of these advantages.

Background Tumor regression grade (TRG) after neoadjuvant therapy is reportedly predictive of prognosis in esophageal cancer patients, as lack of a response to neoadjuvant therapy is associated with a poor prognosis. However, there is little information available on the timing and pattern of recurrence after esophagectomy for thoracic esophageal squamous cell carcinoma (TESCC) that takes into consideration TRG after neoadjuvant chemoradiotherapy (NACRT). Here, in an effort to gain insight into a treatment strategy that improves the prognosis of NACRT non-responders, we evaluated the patterns and timing of recurrence in TESCC patients, taking into consideration TRG after NACRT. Methods A total of 127 TESCC patients treated with NACRT and esophagectomy between 2009 and 2017 were enrolled in this observational cohort study. TRGs were assigned based on the proportion of residual tumor cells in the area (TRG1, ≥1/3 viable cancer cells; 2, < 1/3 viable cancer cells; 3, no viable cancer cells). We retrospectively investigated the timing and patterns of recurrence and the prognoses in TESCC patients, taking into consideration TRG after NACRT. Results The 127 participating TESCC patients were categorized as TRG1 (42 patients, 33%), TRG2 (56 patients, 44%) or TRG3 (29 patients, 23%). The locoregional recurrence rate was higher in TRG1 (36.4%) patients than combined TRG2–3 (7.4%) patients. Patients with TRG3 had better prognoses, though a few TRG3 patients experienced distant recurrence. There were no significant differences in median time to first recurrence or OS among patients with locoregional or distant recurrence. There was a trend toward better OS in TRG2–3 patients with recurrence than TRG1 patients with recurrence, but the difference was not significant. Conclusions NACRT non-responders (TRG1 patients) experienced higher locoregional recurrence rates and earlier recurrence with distant or locoregional metastasis. TRG appears to be useful for establishing a strategy for perioperative treatments to improve TESCC patient survival, especially among TRG1 patients. (303 words).

Abstract
BACKGROUND Patients with 18F-fluorodeoxyglucose-positron emission tomography (FDG-PET)-positive lymph nodes before treatment have a poor prognosis after esophagectomy. This study investigated whether FDG uptake into lymph nodes on FDG-PET (PET-N) during the pre- or posttreatment stage is more predictive of survival for thoracic esophageal squamous cell carcinoma (TESCC) patients who received neoadjuvant chemoradiotherapy (NACRT) followed by esophagectomy. METHODS Of 129 TESCC patients with clinical lymphatic metastasis who underwent curative-intent esophagectomy after NACRT between 2010 and 2018, 97 who received PET before and after NACRT were enrolled in the study. The study defined lymph nodes with a maximum standardized uptake value (SUVmax) greater than 2.5 on FDG-PET before NACRT as cPET-N(+) and after NACRT as CRT-cPET-N(+). Both the cPET-N(+) and CRT-cPET-N(-) patients were defined as PET-N responders. Survival was analyzed using the Kaplan-Meier method and Cox proportional hazard models. RESULTS No significant difference in survival was detected between the cPET-N(+) and cPET-N(-) patients. However, the CRT-cPET-N(-) patients had significantly better 5-year overall survival (OS) and disease-specific survival (DSS) than the CRT-cPET-N (+) patients. The PET-N responders had significantly better 5-year OS and DSS than the PET-N non-responders, and PET-N response was an independent prognostic factor for 5-year DSS. CONCLUSION The PET-N response is a highly predictive prognostic marker for TESCC patients who undergo NACRT followed by esophagectomy. The PET-N response may help clinicians to establish a strategy for perioperative treatments that improves survival for patients with lymph node metastasis in TESCC.

Abstract
To address the major issue of regional disparity in the treatment for elderly cancer patients in an aging society, we compared the treatment strategies used for elderly patients with thoracic esophageal cancer and their survival outcomes in metropolitan areas and other regions. Using the national database of hospital‐based cancer registries in 2008‐2011, patients aged 75 years or older who had been diagnosed with thoracic esophageal cancer were enrolled. We divided the patients into two groups: those treated in metropolitan areas (Tokyo, Kanagawa, Osaka, Aichi, Saitama, and Chiba prefectures) with populations of 6 million or more and those treated in other areas (the other 41 prefectures). Compared were patient backgrounds, treatment strategies, and survival curves at each cancer stage. In total, 1236 (24%) patients from metropolitan areas and 3830 (76%) patients from nonmetropolitan areas were enrolled. Patients in metropolitan areas were treated at more advanced stages. There was also a difference in treatment strategy. The 3‐year survival rate among cStage I patients was better in metropolitan areas (71.6% vs. 63.7%), and this finding mainly reflected the survival difference between patients treated with radiotherapy alone. For cStage II‐IV patients, there were no differences. Multivariable Cox proportional hazard analysis including interaction terms between treatment areas, cStage, and the first‐line treatments revealed that treatments in the metropolitan areas were significantly associated with better survival among patients treated with radiotherapy alone for cStage I cancer. Treatment strategies for elderly patients with thoracic esophageal cancer and its survival outcomes differed between metropolitan areas and other regions.

Abstract
Esophageal cancer recurrence in solitary mediastinal lymph node that may possibly been left behind in the first surgery differs from other recurrence patterns because it is still local disease and offers the possibility of complete cure through resection, but it is technically difficult. We resected recurrent mediastinal lymph nodes in six cases. A left transthoracic approach was used in three patients. Other approaches were left thoracoabdominal, right open transthoracic and transcervical. R0 resections were achieved in five patients without severe surgical stress or postoperative complications. Overall survival after resection of recurrent lymph nodes was 43 (16-82) months. Approaches to resection of recurrent solitary mediastinal lymph nodes after esophagectomy should be consider to perform curative treatment safely and less invasively.

Abstract
Background Video-assisted thoracoscopic surgery (VATS) is being used to treat esophageal submucosal tumors (SMTs) all over the world. However, this technique is difficult when the tumor is large and located on the left side wall of the esophagus, within the upper mediastinum. This is because, with VATS, the surgical forceps have a limited range of motion. Robot-assisted thoracoscopic surgery (RATS) using the da Vinci surgical system may be extremely useful for enucleation of esophageal SMTs within the narrow upper mediastinum. Case presentation A female in her thirties experiencing epigastric pain visited our hospital and was diagnosed with a large esophageal leiomyoma within the upper mediastinum. From its size (10 cm), it was judged to have malignant potential. We performed SMT enucleation using RATS with a da Vinci surgical system Xi. This was our second case using this system. The patient was placed in the left lateral position. Four da Vinci trocars (8 mm) were inserted into the 10th, 7th, 5th and 3rd intercostal spaces (ICS), and an assist port was added in the 5th ICS. We opened the superior mediastinal pleura cranially and caudally from the arch of the azygos vein and expanded the superior mediastinum after dividing the azygos vein. We made an incision in the muscular layer of the esophagus and, using a monopolar hook and monopolar scissors, enucleated the esophageal tumor in a protective manner so as not to damage its capsule or mucosa while applying appropriate robot-specific counter traction. We then sewed up the muscularis using 4–0 Vicryl, inserting the endoscope into the thoracic esophagus to substitute for a bougie. In addition, the pleura was sutured using barbed suture. The surgical procedure was straightforward and smooth. The patient was discharged on postoperative day 4 with no surgical complications. The tumor was definitively diagnosed pathologically from paraffin sections as a benign esophageal leiomyoma. Conclusions RATS enables more delicate and precise esophageal SMT enucleation without surgical complications, though various challenges remain to be overcome.

Abstract
Background A pathological complete response (pCR) after neoadjuvant chemoradiotherapy (NACRT) ensures long-term survival in esophageal squamous cell carcinoma (ESCC) patients following esophagectomy, but pCR patients are a minority. The aim here was to identify prognostic factors in patients with non-pCR ESCC after NACRT. Methods This is a retrospective study. Investigated were 5-year overall survival (OS), disease-specific survival (DSS), and relapse-free survival (RFS) among non-pCR ESCC patients divided into pT0N0, primary site pCR (pT0N+), lymph node pCR (pT+N0), and non-pCR in both the tumor and lymph node (pT+N+) subgroups after NACRT and esophagectomy. Focusing on the SUVmax reduction rate in the primary tumor in 88 patients who underwent FDG-PET before and after NACRT, we used univariate and multivariate Cox proportional hazard models to identify prognostic factors. Results Although there were no significant survival differences among non-pCR ESCC patients with pT0N+, pT+N0, or pT+N+, survival rate among pT+N+patients was the poorest. After setting a 60% cutoff for the SUVmax reduction rate in the tumor, RFS curves for non-pCR patients significantly differed between patients above the cutoff and those below it. For pT+N+ patients, the SUVmax reduction rate (<60% vs ≥ 60%) was an independent prognostic factor of OS, DSS, and RFS. Conclusion Because ESCC patients with SUVmax reduction rates of <60% in the tumor after NACRT and categorized as pT+N+ after NACRT had significantly poorer prognoses, even after esophagectomy, a change in treatment strategy may be an option to improve survival.

Abstract
BACKGROUND Despite wide acknowledgement of the importance of sarcopenia and prognostic markers such as the neutrophil-to-lymphocyte ratio, the impact on cancer patient survival of the timing of sarcopenia's emergence and its severity is not well understood, nor is the association between sarcopenia and prognostic markers. The aim of this study, therefore, was to investigate the effect of the severity and timing of changes in the psoas muscle index (PMI) on survival of advanced esophageal squamous cell carcinoma (ESCC) patients receiving neoadjuvant chemoradiotherapy (NACRT) plus esophagectomy and the association between PMI and known prognostic markers. METHODS Included in this study were 113 ESCC patients who underwent NACRT followed by esophagectomy. PMI and prognostic markers were measured at their initial visit, just before surgery (after NACRT), and 3 months postoperatively. RESULTS All patients were classified into four groups according to the percent decrease in PMI after NACRT and after NACRT plus esophagectomy. Patients exhibiting a larger PMI decrease (≥20%) after NACRT plus esophagectomy had significantly poorer overall survival than those showing a smaller PMI decrease. Furthermore, multivariable analysis showed that a larger decrease in PMI after NACRT plus esophagectomy was a significant risk factor for overall (P < 0.0001) and recurrence-free (P = 0.0097) survival. Neither pretherapeutic PMI nor a decrease in PMI after NACRT significantly affected survival. PMI also showed weak, but significant, correlations with several prognostic markers postoperatively. CONCLUSIONS Decreased PMI after NACRT plus esophagectomy is a strong prognostic indicator in ESCC patients.

Abstract
The relationship between the SLC31A1 (protein: copper transporter 1) rs10981694 A > C and ATP7B (protein: P-type adenosine triphosphatase 7B) rs9535828 A > G polymorphisms on the overall survival and disease-free survival of 104 Japanese patients with esophageal squamous cell carcinoma (ESCC) receiving neoadjuvant chemoradiotherapy (CRT) was investigated. Chemotherapy consisted of protracted infusion of 5-fluoracil (800 mg/m2/day) on days 1-5 and cisplatin or nedaplatin (80 mg/m2/day) on day 1. The median (range) follow-up was 47 (6-127) months. The 5-year overall and disease-free survival rates were 71.2% and 60.6%, respectively. The 5-year overall survival rate was significantly higher in patients with the SLC31A1 rs10981694 C allele compared with the rs10981694 A/A genotype (91.7% vs. 65.0%, P = 0.018). The 5-year disease-free survival rate was significantly higher in patients with the SLC31A1 rs10981694 C allele compared with the rs10981694 A/A genotype (79.2% vs. 55.0%, P = 0.043). In addition, univariate and multivariate analyses showed the SLC31A1 rs10981694 A > C polymorphism to be a significant prognostic factor affecting 5-year overall survival after neoadjuvant CRT. However, the overall and disease-free survival rates after surgery did not differ significantly among the ATP7B rs9535828 genotypes. In conclusion, only the SLC31A1 rs10981694 A/A genotype was an independent predictor of a poorer 5-year overall survival. Therefore, in neoadjuvant CRT for ESCC patients, the effect of platinum was affected by the SLC31A1 rs10981694 A > C polymorphism. The presence of this polymorphism should be considered when devising neoadjuvant CRT regimens or treatment strategies for ESCC.

Abstract
BACKGROUND The interval between preoperative chemoradiotherapy and surgery reportedly affects perioperative outcomes and survival; however, the optimal interval in esophageal cancer patients remains uncertain. OBJECTIVE Our aim was to determine whether a prolonged interval between preoperative neoadjuvant chemoradiotherapy (NACRT) and esophagectomy affects the outcomes of esophageal cancer patients. METHODS A total of 131 patients with esophageal cancer received curative surgery following NACRT at Akita University Hospital between 2009 and 2017. We divided these patients into two groups based on the median interval from NACRT to esophagectomy, and compared the rates of pathological complete response (pCR), surgical outcomes, and survival. RESULTS The median interval from NACRT to esophagectomy was 39 days (range 21-95). Of the 131 patients, 70 (53%) received esophagectomy after 39 days or more from completion of NACRT. There were no significant differences in the clinicopathological features, including pCR rates, between the two groups. Prolongation of the interval from NACRT to esophagectomy was significantly associated with an increased rate of anastomotic leakage and recurrent laryngeal nerve palsy (p = 0.0225 and p = 0.0022, respectively); however, no association with overall survival was detected. CONCLUSIONS A prolonged interval between NACRT and esophagectomy had no impact on pCR rates or survival. However, delaying esophagectomy may increase the likelihood of surgical complications such as anastomotic leakage and recurrent laryngeal nerve palsy.

Abstract
BACKGROUND/AIM The platelet distribution width (PDW) and serum C-reactive protein (CRP) levels are known to be predictive of prognosis in various malignancies. Our aim was to determine whether combining PDW and serum CRP levels produces a prognostic indicator for esophageal cancer (EC) patients. PATIENTS AND METHODS A total of 168 EC patients who underwent neoadjuvant therapy prior to esophagectomy were included in this study. RESULTS We defined a combined PDW and CRP (CPC) score as follows: patients with both low pretherapeutic PDW (≤12.4 fl) and high postoperative serum CRP levels (≥0.5 mg/dl) were assigned a score of 2, while patients with one or neither of those were assigned a score of 1 or 0. A multivariable analysis showed that the CPC score was a significant risk factor for overall (p=0.006) and recurrence-free (p=0.004) survival. CONCLUSION The CPC score is a strong prognostic indicator in EC patients.

Abstract
BACKGROUND Poor oral health is an independent risk factor for upper aerodigestive tract cancers, including esophageal squamous cell carcinoma (ESCC). The pattern recognition receptor Toll-like receptor 4 (TLR4) recognizes lipopolysaccharide in the cell walls of Gram-negative periodontal pathogens associated with the development and progression of ESCC. It is, therefore, plausible that TLR4 plays a crucial role in the pathogenesis of ESCC. METHODS We used an ESCC tissue microarray to confirm expression of TLR4 in patients with ESCC and to determine whether TLR4 expression status correlates with the clinicopathological features of these patients or their prognosis after esophagectomy. We also tested whether the combined expression statuses of TLR4 and TLR3 better correlate with prognosis in these patients than either parameter alone. RESULTS Clinical ESCC samples from all 177 patients tested showed expression of TLR4. Moreover, high TLR4 expression (3 + and 2 +) correlated with poorer 5-year overall survival after esophagectomy than lower TLR4 expression (1 +) (p = 0.0491). Patients showing high TLR4 expression tended to have a poorer prognosis whether treated with surgery alone or with surgery and adjuvant chemotherapy. Univariate and multivariate analyses showed TLR4 expression status to be an independent prognostic factor affecting 5-year overall survival. Patients exhibiting high TLR4 expression with low TLR3 expression had a much poorer prognosis than other patients (p = < 0.0001). CONCLUSION High TLR4 expression predicts a poor prognosis in advanced thoracic ESCC patients after esophagectomy.

Abstract
Esophageal squamous cell carcinoma (ESCC) is one of the most fatal types of malignant tumors worldwide. Epitranscriptome, such as N6 -methyladenosine (m6 A) of mRNA, is an abundant post-transcriptional mRNA modification and has been recently implicated to play roles in several cancers, whereas the significance of m6 A modifications is virtually unknown in ESCC. Analysis of tissue microarray of the tumors in 177 ESCC patients showed that higher expression of m6 A demethylase ALKBH5 correlated with poor prognosis and that ALKBH5 was an independent prognostic factor of the survival of patients. There was no correlation between the other demethylase FTO and prognosis. siRNA knockdown of ALKBH5 but not FTO significantly suppressed proliferation and migration of human ESCC cells. ALKBH5 knockdown delayed progression of cell cycle and accumulated the cells to G0/G1 phase. Mechanistically, expression of CDKN1A (p21) was significantly up-regulated in ALKBH5-depleted cells, and m6 A modification and stability of CDKN1A mRNA were increased by ALKBH5 knockdown. Furthermore, depletion of ALKBH5 substantially suppressed tumor growth of ESCC cells subcutaneously transplanted in BALB/c nude mice. Collectively, we identify ALKBH5 as the first m6 A demethylase that accelerates cell cycle progression and promotes cell proliferation of ESCC cells, which is associated with poor prognosis of ESCC patients.

Abstract
BACKGROUND Preoperative clinical diagnosis of lymph node (LN) metastasis and subsequent pathological diagnosis are often not in agreement. Detection of false-negative LNs is essential in selecting an optimal treatment strategy, and most importantly, the presence of false-negative LN is itself a significant prognostic indicator. Therefore, at present, there is an urgent need to establish more accurate and individualized evaluation methods for LN metastasis. METHODS Of 213 cN0 patients who underwent curative esophagectomy without preoperative neoadjuvant treatment, 60 (28%) had LN metastasis diagnosed pathologically. There were 129 false-negative LNs, of which 85 were detectable by preoperative computed tomography (CT). We retrospectively investigated the distribution, frequency, and characteristics of pathologically positive nodes in patients with clinically N0 esophageal cancer. RESULTS The paracardial region was the most frequent region of false-negative LNs, accounting for 26% (22 LNs) of the total incidence. False-negative LNs distributed widely from the neck to the abdomen in patients with a primary tumor in the middle thoracic esophagus. In patients with a primary tumor in the lower thoracic esophagus, four false-negative LNs were detected in the superior mediastinum. When the short-axis diameter, shape, and attenuation patterns of the LNs were used as criteria for metastasis diagnosis, they were insufficient for an accurate diagnosis. However, false-negative LNs in the most frequently occurring sites are characterized by smaller short-axis, suggesting that accurate diagnosis cannot be made unless the diagnostic criteria for the short-axis are reduced in addition to shape and attenuation. CONCLUSIONS Although restrictive to the most frequent regions of false-negative LNs occur, reducing size criterion and consideration of their shape and attenuation may contribute to improved diagnosis.

Abstract
BACKGROUND/AIM The potential advantages of robot-assisted thoracoscopic esophagectomy (RATE) have yet to be verified. This study focused on the degree of lymph node dissection around the left recurrent laryngeal nerve (RLN). PATIENTS AND METHODS A total of 21 consecutive patients who received RATE (RATE group) and 38 who received conventional thoracoscopic esophagectomy (TE) (TE group), both with extended lymphadenectomy, for thoracic squamous cell esophageal carcinoma, were enrolled in this study. We compared the numbers of lymph nodes dissected from the mediastinum, especially around the left RLN. RESULTS The median number of lymph nodes dissected from around the left RLN was 6 in the RATE group and 4 in the TE group, and the ratio of the dissected lymph nodes around the left RLN to all lymph nodes was significantly higher in the RATE group (p=0.048). CONCLUSION Our findings indicate that a robot-assisted surgical system enables for more extensive dissection of lymph nodes around the left RLN.

Abstract
BACKGROUND The relationship between Toll-like receptors (TLRs) and esophageal squamous cell carcinoma (ESCC) is not completely understood. METHODS RT-qPCR was used to evaluate the mRNA expression of TLR1-10 in 13 ESCC lines. We then used ESCC tissue microarray (TMA) to confirm expression of TLR3 protein in patients with ESCC. RESULTS All ESCC lines showed 10-60 times higher TLR3 mRNA expression than PBLs. High expression of TLR3 correlated with favorable 5-year overall survival (OS) and disease specific survival (DSS) among patients with ESCC after esophagectomy (p < 0.01). Additionally, In the adjuvant chemotherapy group, TLR3 high patients had significantly better 5-year OS compared to TLR3 low patients (60.2%, 34.4%, respectively) but not in the surgery alone group. CONCLUSION High TLR3 expression is an independent prognostic factor and has the potential to serve as a clinically useful marker of the need for adjuvant chemotherapy after esophagectomy in patients with advanced thoracic ESCC.

Abstract
AIM We investigated the safety of adding Japanese-style extended 3-field lymphadenectomy in patients treated with neoadjuvant chemoradiotherapy (NACRT) for thoracic esophageal squamous cell carcinoma (TESCC). Furthermore, the efficacy of NACRT, as shown by the pathological and metabolic responses were determined. PATIENTS AND METHODS One hundred consecutive patients with cStage II-IV TESSC were enrolled. We analyzed the adverse events related to NACRT and surgical complications following surgery. Pathological responses to NACRT and the association between pCR and [18F]-fluorodeoxyglucose positron-emission tomography (FDG-PET) evaluation were investigated. RESULTS Adding Japanese-style extended 3-field lymph node dissection after NACRT did not increase serious surgical complications. Seventy-four percent of patients experienced grade 2-3 pathological response, with 25% achieving pCR. There was a significant relationship between the change from positive to negative findings on FDG-PET/CT and pCR. CONCLUSION Transthoracic esophagectomy with Japanese-style extended 3-field lymph node dissection after NACRT is a safe and powerful treatment.

Abstract
BACKGROUND CXCL10, a member of the CXC chemokine family, is known to mediate chemotaxis, apoptosis, angiogenesis, and cell growth. It is also reportedly involved in tumor development and can affect prognosis in several cancers. However, the precise relationship between CXCL10 and the prognosis of patients with esophageal squamous cell carcinoma (ESCC) is not fully understood. METHODS We used ESCC tissue microarrays containing samples from 177 patients to test whether the CXCL10 expression status, determined using immunohistochemical analysis, is predictive of prognosis. We also tested whether CXCL10 expression status could serve as a clinically useful marker for evaluating the need for adjuvant chemotherapy after surgery. RESULTS We found that high CXCL10 expression in clinical samples was an independent prognostic factor and was predictive of a favorable 5-year overall survival and disease-specific survival (p = 0.0102 and 0.0332, respectively). Additionally, no significant difference was detected between patients in the CXCL10-high group treated with surgery alone and those treated with surgery followed by adjuvant chemotherapy. In the CXCL10-low group, on the other hand, patients treated with surgery followed by adjuvant chemotherapy had better 5-year overall survival than those treated with surgery alone. CONCLUSIONS High CXCL10 expression is an independent prognostic factor and has the potential to serve as a clinically useful marker of the need for adjuvant chemotherapy after surgery in patients with advanced thoracic ESCC.

Abstract
INTRODUCTION The surgical technique for esophagectomy to treat esophageal malignancies has been improved over the past several decades. Nevertheless, it remains extremely difficult to surgically treat patients with locally advanced T4b tumors invading the aorta or respiratory tract. PRESENTAION OF CASE A 37-year-old Japanese man was diagnosed with T4b (descending aorta) N2M0, Stage IIIC middle thoracic esophageal squamous cell carcinoma. He was initially treated with definitive CRT followed by 3 courses of DCF. After the DCF, CT showed that the main tumor had shrunk and appeared to have separated from the descending aorta. Therefore we decided to perform a salvage esophagectomy. Because we needed the ability to closely observe the site of invasion to determine whether aortic invasion was still present, half the esophageal resection was performed under right thoracotomy, but the final resection at the invasion site was performed under left thoracotomy. Consequently, the thoracic esophagus was safely removed and aortic replacement was avoided. The patient has now survived more than 30 months after the salvage esophagectomy with no additional treatment for esophageal cancer and no evidence of recurrent disease. DISCUSSION Because this and the previously reported procedures, each have particular advantages and disadvantages, one must contemplate and select an approach based on the situation for each individual patient. CONCLUSION Salvage esophagectomy through a right thoracotomy followed by careful observation of the invasion site for possible aortic replacement through a left thoracotomy is an optional procedure for these patients.

Abstract
BACKGROUND Regenerating gene 1A (REG1A) plays an important role in tissue regeneration and in cell proliferation in the mucous membrane of the gastrointestinal tract. We previously reported that the positive expression status of REG1A was predictive of chemoradiosensitivity in patients treated with preoperative chemoradiotherapy before esophagectomy or with definitive chemoradiotherapy. To further confirm the utility of REG1A as a chemosensitivity marker, we carried out an additional retrospective clinical study aimed at determining whether REG1A is a reliable chemosensitivity marker in patients treated with esophagectomy followed by adjuvant chemotherapy. METHOD A total of 177 patients with T2-4 thoracic esophageal squamous cell carcinoma received curative surgery without preoperative treatment at Akita University Hospital between 2001 and 2011. A tissue microarray was constructed, and REG1A expression status was analyzed immunohistochemically. We then statistically analyzed the relationships between REG1A expression status and 5-year overall survival (OS), disease-specific survival (DSS), and disease-free survival (DFS). RESULTS In the adjuvant group (n=105), REG1A-positive patients showed significantly better prognoses than REG1A-negative patients. (5-year OS, p=.0022; DSS, p=.0004; and DFS, p=.0040). However, there were no significant differences between REG1A-positive and REG1A-negative patients in the surgery group (n=72). Univariate and multivariate analyses showed REG1A expression status to be a significant prognostic factor affecting 5-year DSS, comparable to lymph node metastatic status. CONCLUSION The present study suggests REG1A expression status has the potential to be a highly reliable and clinically useful chemosensitivity marker in patients treated with advanced thoracic esophageal squamous cell carcinoma. REG1A expression status will provide a good indication of treatment strategy and enable more individualized treatment for patients.

Abstract
PURPOSE To evaluate the effects of topical betaxolol on experimental ocular inflammation. METHODS Transcorneal diffusion of 25 microg/mL (7.09 x 10(-2) mmol/L) of prostaglandin E(2) (PGE(2)), placed in a glass cylinder, was employed to induce aqueous flare elevation in pigmented rabbits. Betaxolol was administered topically before PGE(2) application. Aqueous flare was measured with a laser flare cell meter. RESULTS Four-, two-, and one-time topical instillations of betaxolol inhibited the PGE(2)-induced aqueous flare elevation by 44% +/- 8%, 32 +/- 7%, and 8 +/- 6%(mean +/- SD), respectively. The inhibition of flare elevation was dependent on the number of betaxolol instillations. CONCLUSION Topical betaxolol has an inhibitory effect on PGE(2)-induced aqueous flare elevation in rabbit eyes.

Abstract
We investigated the effects of Orengedoku-to (Huanglian-Jie-Du-Tang in Chinese) and Senkanmeimoku-to (Xygan-Ming-Mu-Tang in Chinese), traditional herbal medicines, on experimantal elevation of aqueous flare in pigmented rabbits. To produce the elevation of aqueous flare in rabbits, prostaglandin E2 (PGE2) was applied to the cornea with use of a glass cylinder, or lipopolysaccharides (LPS) were injected into the ear vein. Animals were pretreated by the oral administration of 150 g/day of food containing 0.7%, 0.2% or 0.07% (w/w) Orengedoku-to, or 2%, 0.6% or 0.2% (w/w) Senkanmeimoku-to for 5 days. Aqueous flare was measured with a laser flare-cell meter. Pretreatment with 0.7% or 0.2% Orengedoku-to and 2% Senkanmeimoku-to did suppress significantly (P < 0.05) elevation of aqueous flare induced by PGE2. Pretreatment with 0.7% or 0.2% Orengedoku-to and 2% or 0.6% Senkanmeimoku-to significantly suppressed (P < 0.001) elevation of aqueous flare induced by LPS. It is possible that Orengedoku-to and Senkanmeimoku-to may migrate some forms of uveitis.

Abstract
We evaluated the effects of intravitreal injection of methanol, formaldehyde, or formate on rabbit eyes. One hundred microl of 1% methanol, 1% or 0.1% formaldehyde, or 1% formate was injected in the vitreous cavity of the right eyes of rabbits. The eyes were examined by biomicroscopy and ophthalmoscopy weekly. One month after injection, the eyes were enucleated and examined histologically. One week after treatment the animals that received 0.1% formaldehyde showed retinal vessel dilation, and the rabbits that received 1% formaldehyde showed mild posterior subcapsular cataract and retinal vessel dilation and haemorrhages. One month after treatment, the animals that received 0.1% or 1% formaldehyde developed mild posterior subcapsular cataract and retinal lesions. Animals that received 1% methanol or 1% formate showed nearly normal optical media and fundi. Histologically disorganized retina and optic nerve were seen in eyes that received 0.1% or 1% formaldehyde. Eyes that received 1% methanol or 1% formate appeared histologically normal. Our findings indicate that intravitreal injection of formaldehyde causes retinal and optic nerve damage, while methanol and formate are not or less toxic to ocular tissues.

Abstract
We examined the disruptive effect of highly selective agonists for prostaglandin E2 receptor subtypes (EP1, EP2, EP3 and EP4) on the blood-aqueous barrier, and evaluated the inhibitory effect of tetramethylpyrazine, an active component of Ligusticum wallichii, on the elevation of aqueous flare induced by the EP agonists in pigmented rabbits. Highly selective EP agonists (ONO-DI-004, EP1 agonist; ONO-AE1-259-01, EP2 agonist; ONO-AE-248, EP3 agonist; ONO-AE1-329, EP4 agonist) at 12.5 to 250 microg/ml were transcorneally administered to the eyes of pigmented rabbits using a glass cylinder. Animals were pretreated intravenously with tetramethylpyrazine (10 or 30 mg/kg) 30 minutes before application of the EP2 or the EP4 agonist. Aqueous flare was measured using a laser flare-cell meter. Aqueous flare intensity was expressed as the area under the curve (AUC) in arbitrary units. After administration of ONO-AE1-259-01 or ONO-AE1-329, aqueous flare increased and then gradually decreased. ONO-DI-004 and ONO-AE-248 had almost no effect on aqueous flare elevation. The AUC of eyes in rabbits pretreated with tetramethylpyrazine, 10 or 30 mg/kg i.v., was significantly smaller than that of eyes in rabbits treated with ONO-AEI-259-01 alone. The AUC of eyes in rabbits pretreated with tetramethylpyrazine, 10 or 30 mg/kg i.v., was not significantly smaller than that of eyes in rabbits treated with ONO-AEI-329 only. The results indicated that EP2 and EP4 agonists induced aqueous flare elevation in pigmented rabbits, and that tetramethylpyrazine inhibited the aqueous flare elevation induced by the EP2 agonist but did not suppress the elevation induced by the EP4 agonist.

Abstract
PURPOSE To evaluate the effect of tetramethylpyrazine on the elevation of aqueous flare and intraocular pressure (IOP) induced by prostaglandin (PG) E(2) and PGE(2) receptor (EP) agonists. METHODS PGE(2) or EP agonists (11-deoxy PGE(1), EP(2) agonist; 17-phenyl trinor PGE(2), EP(1) and EP(3) agonist; or sulprostone, EP(1) and EP(3) agonist), 25 microg/mL, were transcorneally administered to pigmented rabbits. Animals were pretreated with tetramethylpyrazine intravenously (10 or 30 mg/kg) or topically (0.1% solution). Aqueous flare was measured using a laser flare-cell meter, and the intensity was expressed as the area under the curve (AUC). Intraocular pressure was measured using a noncontact tonometer. RESULTS After administration of PGE(2), aqueous flare and IOP increased and then gradually decreased. The AUC of eyes pretreated with tetramethylpyrazine, 10 or 30 mg/kg, intravenously, or topical 0.1% solution, was significantly smaller than that of the controls. The mean Delta IOP of eyes pretreated with tetramethylpyrazine, 30 mg/kg intravenously, was significantly lower than that of the controls. After administration of 11-deoxy PGE(1), aqueous flare increased and then gradually decreased. 17-phenyl trinor PGE(2) and sulprostone did not disrupt the blood-aqueous barrier. The AUC of eyes pretreated with tetramethylpyrazine, 10 or 30 mg/kg, intravenously, before 11-deoxy PGE(1) application was significantly smaller than that of the controls. CONCLUSION The results indicated that tetramethylpyrazine inhibited PGE(2)- or 11-deoxy PGE(1)-induced elevation of aqueous flare and IOP.

Abstract
PURPOSE To evaluate the effects of the alpha(2)-adrenergic agonists (clonidine, apraclonidine, and guanfacine) on lipopolysaccharide (LPS)-induced aqueous flare elevation in pigmented rabbits. METHODS Anterior uveitis was induced with an intravenous injection of LPS (0.5 microg/kg) in an ear vein. The reproducibility of experimental uveitis induced by LPS (0.5 microg/kg) was also determined. Clonidine (0.01, 0.05, 0.25, or 1%), apraclonidine (1%), or guanfacine (1%) was topically instilled in the right eye 30 and 5 minutes before and 30 minutes after LPS application (N = 6 animals, respectively). Clonidine (0.25%) was topically administered three times at 30-minute intervals from 240 or 120 minutes before, or 120 or 240 minutes after LPS application (N = 6 animals, respectively). Then 1 mg/kg of yohimbine was injected into an ear vein 30 minutes before each topical three-time instillation of clonidine 1%, apraclonidine 1% or guanfacine 1% (N = 6 animals, respectively). Aqueous flare was measured with a laser flare-cell meter. Aqueous flare elevation was expressed as the area under the curve (AUC) in arbitrary units. Rabbits received the first LPS intravenous injection, and the control values of the AUC were obtained. Three months later, the alpha(2)-agonist and the second LPS administration were given to the same animals. RESULTS The AUCs (5,184 +/- 1,255 units) after the first application of LPS were similar to those (5,033 +/- 1,290) after the second application 3 months after the first administration. Topical instillation of clonidine inhibited LPS-induced aqueous flare elevation in a dose-dependent manner (0.01-0.25%). Topical instillation of clonidine 1%, apraclonidine 1% or guanfacine 1% inhibited LPS-induced aqueous flare elevation by 98 +/- 2.0% (mean +/- SD), 86 +/- 14% and 94 +/- 5.7%, respectively. Pretreatment with intravenous yohimbine prevented the inhibitory effect on flare elevation induced by each agent. CONCLUSION The present findings suggested that topical instillation of some alpha(2)-agonists may have an inhibitory effect on ocular inflammation, which is mediated in part by alpha(2)-receptors.

Abstract
PURPOSE To evaluate the possible inhibitory effects of hot water extract of Scutellariae radix and its major components (baicalein, baicalin, and wogonin) on experimental elevation of aqueous flare in pigmented rabbits. METHODS To produce aqueous flare elevation in rabbits, prostaglandin E(2) (PGE(2)), 25 microg/mL, was applied to the cornea with the use of a glass cylinder, or lipopolysaccharides (LPS), 0.5 microg/kg, were injected into an ear vein. Animals were pretreated by the oral administration of 150 g/day of food containing 0.02%, 0.07%, or 0.2% (w/w) extract of Scutellariae radix for 5 days, or by intravenous injection of baicalein, baicalin, or wogonin, 60 microg/kg or 600 microg/kg, 30 minutes before experimental uveitis was induced. Aqueous flare was measured with a laser flare-cell meter. Aqueous flare intensity was expressed as the area under the curve (AUC) in arbitrary units. RESULTS The AUC of PGE(2)- and LPS-induced aqueous flare elevation was 1,343 and 5,066 arbitrary units, respectively. Pretreatment by oral administration of 0.07% or 0.2% extract of Scutellariae radix did not inhibit PGE(2)-induced aqueous flare elevation (AUC: 1,252 and 1,210, respectively), but it did inhibit LPS-induced aqueous flare elevation (AUC: 2,248 and 1,973, respectively). Pretreatment by intravenous injection of 600 microg/kg of baicalein, baicalin, or wogonin inhibited LPS-induced aqueous flare elevation (AUC: 2,289, 2,163, and 1,509, respectively). Pretreatment with 60 microg/kg of wogonin also inhibited LPS-induced aqueous flare elevation (AUC: 1,980). CONCLUSION Hot water extract of Scutellariae radix may have an inhibitory effect on experimental anterior uveitis induced by LPS in pigmented rabbits.

Abstract
We evaluated prospectively the effects of traditional Sino-Japanese herbal medicines on elevation of aqueous flare. Fifty-four patients with age-related cataract undergoing phacoemulsification with intraocular lens implantation were studied. In the control group, 20 patients received no herbal medicine. In the treated groups, 14 patients were given Orengedoku- to (Huanglian-Jie-Du-Tang in Chinese) granules (7.5 g daily), 10 patients were given Kakkon-to (Ge-Gen-Tang in Chinese) granules (7.5 g daily), and 10 patients were given Sairei-to (Cai-Ling-Tang in Chinese) granules (9.0 g daily), for 3 days before surgery, the day of surgery, and for 7 days after surgery. Aqueous flare was measured before and after surgery. The differences in preoperative flare intensities among the four groups were not significant. In the control group, the flare was 29.4 photon counts/msec on day 1, and then gradually decreased. The flare intensities on days 1, 3, and 5 in the Orengedoku-to and Kakkon-to groups were significantly lower than in the control group. The flare intensities in the Sairei-to group were the same as those of the controls. Oral administration of Orengedoku-to and Kakkon-to decreased aqueous flare elevation after small-incision cataract surgery. Sairei-to had no effect on the elevation.

METHODS Case report of a 60-year-old woman who complained of fever, chills, headache, lymphadenopathy, and blurred vision in the right eye following an insect bite to the lower right forehead. RESULTS Serological findings showed elevated titers for the strains of Rickettsia tsutsugamushi. Ophthalmologic examination disclosed bilateral conjunctival injection, flame-shaped hemorrhage in her right fundus, and scattered hemorrhage in her left fundus. Fluorescein angiography demonstrated dye leakage and dilation of capillaries. CONCLUSIONS Branch retinal vein occlusion associated with classical tsutsugamushi disease, as demonstrated in our patient, may be rare.

Abstract
We evaluated serum methanol levels in subjects with or without optic nerve head disease. Serum methanol levels were determined using gas chromatography in 71 patients with optic nerve head disease and in 127 subjects without optic nerve head disease. Their ages ranged from 17 to 89 years. Serum methanol levels in 127 subjects without optic nerve head disease ranged from 0.12 to 3.86 microg/ml (mean +/- standard deviation, 1.72 +/- 0.86 microg/ml). In the subjects without optic nerve head disease, the differences in the levels between those with cataract versus retinal detachment, men versus women, and between each age-group (50-80 years) were not significant. The methanol levels in patients with optic neuritis (n = 2), Wolfram syndrome (n = 1), Leber hereditary optic neuropathy at the late stage (n = 2), retinitis pigmentosa (n = 23), and primary open-angle glaucoma (n = 16) were less than 3.86 microg/ml. Methanol levels in 1 patient with Leber hereditary optic neuropathy at the acute stage was 5.28 microg/ml. Of 10 patients with primary angle-closure glaucoma, 1 had a slightly elevated level and 9 had levels less than 3.86 microg/ml. Of 17 patients with normal tension glaucoma, 5 had methanol levels higher than 3.86 microg/ml, and 12 patients had levels less than 3.86 microg/ml. The present study shows that serum methanol levels in subjects without optic nerve head disease ranged from 0.12 to 3.86 microg/ml and were much lower than the levels that produce acute ocular symptoms of methanol intoxication. It is possible that high serum methanol levels may play a part in the acute stage of Leber hereditary optic neuropathy and normal tension glaucoma in certain patients. It is unlikely that increased serum methanol levels participate in primary angle-closure glaucoma.

Abstract
We evaluated the role of topical clonidine on experimental ocular inflammation. Transcorneal diffusion of prostaglandin (PG) E(2), 7. 09 x 10(-2) mmol/l, with the use of a glass cylinder was employed to produce aqueous flare elevation in pigmented rabbits. Clonidine was topically administered and yohimbine was injected intravenously. Aqueous flare was measured with a laser flare cell meter. Topical instillation of 0.25% clonidine inhibited 89% of PGE(2)-induced aqueous flare elevation. Instillation of clonidine at 60 or 30 min before and 10 min after PGE(2) inhibited flare significantly. Pretreatment with intravenous yohimbine decreased the clonidine-induced inhibition of the flare elevation in a dose-dependent manner. It is possible that the anti-inflammatory action of topical clonidine may be mediated partly by alpha(2)-receptors.

Abstract
A 71-year-old woman with depression had been treated with an antidepressant (maprotiline) and antianxiety agents (clotiazepam and alprazolam). She had previously complained of ocular pain and blurred vision. However, thorough ocular examination was not performed at those times. On examination, visual acuity was no light perception OD and hand motion OS. Intraocular pressures were 33 mm Hg OU. Moderately dilated pupils, atrophic irises, shallow anterior chambers and closed angles were seen in both eyes. Despite treatment, her visual acuity decreased to no light perception bilaterally. Psychiatrists and ophthalmologists should be aware that antidepressants and antianxiety agents can precipitate angle closure glaucoma in susceptible eyes.

Abstract
An 11-year-old boy complained of headache, slight fever and decreased visual acuity. Intracameral cells and serous retinal detachment were found in both eyes. Pleocytosis was seen in the cerebrospinal fluid. Bilateral uveitis diminished rapidly in response to corticosteroid treatment. Depigmentation of the fundi developed several months later. We believe that Vogt-Koyanagi-Harada syndrome in a child, as demonstrated in our patient, may be uncommon.

Abstract
Idiopathic sclerosing inflammation has commonly been found in the diffuse orbital tissues. We report the inflammation of the right upper eyelid in a 65-year-old man. Computed tomography and magnetic resonance imaging showed a diffuse mass localized only in the right upper eyelid. Histologic study of the excised specimen revealed dense collagenous tissue with sparse infiltration of mixed inflammatory cells. Immunohistochemical study showed that the inflammatory cells were largely composed of T cells (UCHL-1), histiocytes (PG-M1) and scattered plasma cells (immunoglobulins). No L26-positive B cells were found. We believe that idiopathic sclerosing inflammation of the upper eyelid, as demonstrated in our patient, may be rare.

Abstract
We evaluated the Cutler-Beard bridge flap technique with the use of donor sclera for upper eyelid reconstruction. The right upper eyelid of a 22-year-old man (case 1) was bitten by a dog. A mass in the left upper eyelid of an 85-year-old man (case 2) was excised. Major full-thickness defects of the eyelid with small loss of tarsus were reconstructed with the use of donor sclera. Good cosmetic results were obtained. Major full-thickness defects of the upper eyelid with small loss of tarsus may be effectively reconstructed by the Cutler-Beard technique with use of donor sclera.

Abstract
A 40-year-old woman had a highly pigmented, slightly elevated tumor on the left optic disc. She had no visual disturbance in the left eye. The tumor was stationary for 5 years. At age 45 years, she complained of decreased visual acuity in the right eye. Magnetic resonance imaging showed a right-shifted homogeneous lesion at the tuberculum sellae. Histopathologic study of the excised lesion revealed interlacing bundles of spindle-shaped fibroblast-like cells with whorl formation. We believe that a relationship between melanocytoma of the optic nerve head and a tuberculum sellae meningioma may exist rather than a chance occurrence, as previously suggested by others.

Abstract
PURPOSE To evaluate the fundus lesions in a young woman. METHODS Visual function, ophthalmoscopy, electrophysiology, fluorescein angiography, and indocyanine green angiography were performed. RESULTS A 24-year-old woman had decreased visual acuity (0.2), granularity in the macula, and multiple yellow-white patches in the fundus, reduced a wave on electroretinography, hyperfluorescence on fluorescein angiography, and hypofluorescence on indocyanine green angiography in the left eye. When visual acuity improved to 1.0, the white dots disappeared ophthalmoscopically, and fluorescein angiography showed normal findings. Hypofluorescent spots were found, however, on indocyanine green angiography. CONCLUSION It is possible that signs of multiple evanescent white dot syndrome may remain longer during examination by indocyanine green angiography than by visual function, ophthalmoscopy, or fluorescein angiography.

Abstract
We have used optokinetic stimulation in patients with unilateral age-related macular degeneration (AMD) and central scotoma to investigate the possible contribution of the central visual field to circular vection (CV). Six patients aged 42-73 years with unilateral AMD and an aged-matched control group of nine elderly adults aged 47-75 years were examined. Monocular visual field defects were verified with the Goldmann perimeter by kinetic perimetry. The device used to induce CV was a random dot pattern projected onto a hemispherical dome with a radius of 75 cm. The pattern was rotated horizontally at a constant acceleration of 1 deg/s2. Monocular stimuli were randomly repeated two to three times in both temporal-nasal (T-N) and nasal-temporal (N-T) directions. The latency of onset of CV was measured for each stimulus presentation. In the age-matched control group the CV latencies varied from 4.2 to 72.0 s. In each case, however, the CV latencies were stable. No significant differences in CV latencies were found between right and left eyes in both stimulus directions (p > 0.05). In patients with AMD, no statistically significant difference in CV latency was found between the affected and unaffected eyes (p > 0.05). Marked central visual field loss in AMD does not significantly impair peripherally induced CV. Our results are compatible with the hypothesis that the peripheral retina dominates CV.

Abstract
PURPOSE To evaluate the efficacy of high-dose methylprednisolone in the treatment of pseudophakic cystoid macular edema (CME). SETTING University-affiliated hospital. METHODS Four patients with pseudophakic CME who reported decreased visual acuities were treated with oral prednisolone (20 mg daily for 5 days), oral acetazolamide (500 mg daily for 5 days), and topical dexamethasone 0.1% and diclofenac 0.1% (4 times a day for 14 days). The CME did not resolve. Next, they were treated with high-dose (1000 mg daily) intravenous methylprednisolone for 3 days. RESULTS In 3 of 4 eyes, the CME resolved and visual acuity improved. CONCLUSION High-dose methylprednisolone may be effective in the treatment of pseudophakic CME.

Abstract
BACKGROUND AND OBJECTIVE To evaluate the efficacy of direct cyclopexy for treatment of traumatic cyclodialysis cleft associated with ocular hypotony. PATIENTS AND METHODS Eyes with traumatic cyclodialysis cleft were treated with direct cyclopexy or 1.0% atropine eyedrop. RESULTS Five eyes with a large cyclodialysis cleft were treated with direct cyclopexy. Postoperatively, these eyes obtained normal intraocular pressure. Four of the 5 eyes had good visual acuity, and 1 eye that had preoperative subretinal hemorrhage in the macula had poor visual acuity. Of the 3 eyes treated with 1.0% atropine eyedrops, 1 had good visual acuity, and 2 with retinal folds had fairly good and poor visual acuity. CONCLUSION The present study showed that direct cyclopexy is useful for the treatment of traumatic cyclodialysis cleft associated with ocular hypotony, and that the cyclodialysis should be surgically treated before irreversible retinal folds develop.
