Abstract
INTRODUCTION Levels of serum selenium (Se) and zinc (Zn) decrease when total parental nutrition (TPN) is administered without trace element supplementation for just a few weeks. These trace elements are involved in thyroid hormone metabolism and their deficiencies cause thyroid dysfunction. However, there have been few reports on the details of its clinical course. CASE PRESENTATION A 50-year-old man presented with thyroid dysfunction due to Se and Zn deficiency. He had an approximately 70-cm residual small intestine after undergoing intestinal resection and he received TPN without trace element supplementation for one and a half months. Blood tests revealed high levels of thyroid-stimulating hormone (TSH) and free thyroxine (FT4) and low levels of free triiodothyronine (FT3). An abnormal pattern of thyroid function led to suspicion of Se deficiency. Se supplementation raised FT3 levels and lowered FT4 levels to within their respective reference ranges; however, subclinical hypothyroidism persisted with transient TSH elevation. We suspected that Zn deficiency also contributed to the hypothyroidism and, therefore, initiated Zn supplementation, which resulted in normalization of thyroid function. DISCUSSION Although thyroid dysfunction has been reported in many studies conducted on Se and Zn deficiencies, hormonal patterns vary between reports. Further accumulation of cases, including detailed data on nutritional status, would be of benefit to elucidate the clinical reality. CONCLUSION It is important to consider Se and Zn deficiencies when TSH and FT4 levels are elevated. It should also be noted that transient TSH elevation may be observed with Se supplementation.

Abstract
Adverse Outcome Pathway (AOP) is a useful tool to glean mode of action (MOE) of a chemical. However, in order to use it for the purpose of risk assessment, an AOP needs to be quantified using in vitro or in vivo data. Majority of quantitative AOPs developed so far, were for single exposure to progressively higher doses. Limited attempts were made to include time in the modeling. Here as a proof-of concept, we developed a hypothetical AOP, and quantified it using a virtual dataset for six repeated exposures using a Bayesian Network Analysis (BN) framework. The virtual data was generated using realistic assumptions. Effects of each exposure were analyzed separately using a static BN model and analyzed in combination using a dynamic BN (DBN) model. Our work shows that the DBN model can be used to calculate the probability of adverse outcome when other upstream KEs were observed earlier. These probabilities can help in identification of early indicators of AO. In addition, we also developed a data driven AOP pruning technique using a lasso-based subset selection, and show that the causal structure of AOP is itself dynamic and changes over time. This proof-of-concept study revealed the possibility for expanding the applicability of the AOP framework to incorporate biological dynamism in toxicity appearance by repeated insults.

Abstract
Pheochromocytomas and paragangliomas (PPGLs) are rare tumors that secrete catecholamines and arise from the adrenal medulla or extra-adrenal sympathetic ganglia. These tumors secrete adrenaline and noradrenaline, but paragangliomas usually produce only noradrenaline because of the lack of phenylethanolamine N-methyltransferase (PNMT) expression. Composite paragangliomas, which are complex tumors consisting of multiple types of neuroblastic cells, are extremely rare. We present the case of a 46-year-old woman with an atypical catecholamine profile who was preoperatively diagnosed with pheochromocytoma. However, postoperative pathology revealed that the patient had an extra-adrenal paraganglioma accompanied by a ganglioneuroma, which led to the diagnosis of a composite tumor. Interestingly, PNMT is expressed in both paragangliomas and ganglioneuromas. In addition, we reviewed reported composite paragangliomas and compared their clinical features with those of composite pheochromocytomas. We also discuss various aspects of the etiology of composite paragangliomas and the mechanism by which PNMT is expressed in tumors.

Abstract
AIMS/INTRODUCTION To evaluate the efficacy of sensor-augmented pump (SAP) for improving obstetric and neonatal outcomes among pregnant women with type 1 diabetes mellitus by comparing it with continuous subcutaneous insulin infusion plus self-monitoring of blood glucose (continuous subcutaneous insulin infusion [CSII]/SMBG). MATERIALS AND METHODS This retrospective cohort study included 40 cases of pregnancy complicated by type 1 diabetes mellitus treated with SAP (SAP group), and 29 cases of pregnancy complicated by type 1 diabetes mellitus treated with CSII/SMBG (CSII/SMBG group). The obstetric and neonatal outcomes were compared between the two groups. RESULTS The median of the glycoalbumin levels in the first (18.8% vs 20.9%; P < 0.05) and second (15.4% vs 18.0%; P < 0.05) trimesters, the hemoglobin A1c levels in the peripartum period (6.1% vs 6.5%; P < 0.05) and the standard deviation score of birthweights (0.36 vs 1.52; P < 0.05) were significantly lower in the SAP group than in the CSII/SMBG group. The incidence rate of large for gestational age newborns was significantly lower in the SAP group than in the CSII/SMBG group (27.5% vs 65.5%; P < 0.05). No significant differences in the incidence rates of hypertensive disorders of pregnancy, small for gestational age, respiratory distress syndrome, neonatal hypoglycemia, hypervolemia and hyperbilirubinemia were observed between the groups. CONCLUSION The present study showed that SAP therapy is more effective in preventing large for gestational age newborns in pregnant women with type 1 diabetes mellitus than CSII/SMBG.

Abstract
BACKGROUND Chromosome 5p partial monosomy (5p-syndrome) and chromosome 6p partial trisomy are chromosomal abnormalities that result in a variety of symptoms, but liver dysfunction is not normally one of them. Alagille syndrome (OMIM #118450) is a multisystem disorder that is defined clinically by hepatic bile duct paucity and cholestasis, in association with cardiac, skeletal, and ophthalmologic manifestations, and characteristic facial features. Alagille syndrome is caused by mutations in JAG1 on chromosome 20 or NOTCH2 on chromosome 1. Here, we report a preterm infant with karyotype 46,XX,der(5)t(5,6)(p15.2;p22.3) and hepatic dysfunction, who was diagnosed as having incomplete Alagille syndrome. CASE PRESENTATION The Japanese infant was diagnosed based on the cardiac abnormalities, ocular abnormalities, characteristic facial features, and liver pathological findings. Analysis of the JAG1 and NOTCH sequences failed to detect any mutations in these genes. CONCLUSIONS These results suggest that, besides the genes that are known to be responsible for Alagille syndrome, other genetic mutations also may cause Alagille syndrome.

Abstract
Pheochromocytoma is a rare but life-threatening condition due to catecholamine release induced by drug treatments such as β-blockers or glucocorticoids. We present a case of hypertensive crisis due to pheochromocytoma, induced after the initiation of dexamethasone and landiolol during intensive care for severe coronavirus disease 2019 (COVID-19). Based on a detailed medical history review, the patient was previously diagnosed with primary aldosteronism by confirmatory tests, moreover, an abdominal computed tomography scan identified an adrenal tumor 2 years before current admission. We tentatively diagnosed the patient with pheochromocytoma and initiated α-blockers without conducting a catecholamine report, leading to stable hemodynamics. We present a successfully managed case of pheochromocytoma concomitant with COVID-19, which has become a global crisis.

Abstract
The Institute for In Vitro Sciences (IIVS) is sponsoring a series of workshops to identify, discuss and develop recommendations for optimal scientific and technical approaches for conducting in vitro assays, to assess potential toxicity within and across tobacco and various next generation nicotine and tobacco products (NGPs), including heated tobacco products (HTPs) and electronic nicotine delivery systems (ENDS). The third workshop (24-26 February 2020) summarised the key challenges and made recommendations concerning appropriate methods of test article generation and cell exposure from combustible cigarettes, HTPs and ENDS. Expert speakers provided their research, perspectives and recommendations for the three basic types of tobacco-related test articles: i) pad-collected material (PCM); ii) gas vapour phase (GVP); and iii) whole smoke/aerosol. These three types of samples can be tested individually, or the PCM and GVP can be combined. Whole smoke/aerosol can be bubbled through media or applied directly to cells at the air-liquid interface. Summaries of the speaker presentations and the recommendations developed by the workgroup are presented. Following discussion, the workshop concluded the following: that there needs to be greater standardisation in aerosol generation and collection processes; that methods for testing the NGPs need to be developed and/or optimised, since simply mirroring cigarette smoke testing approaches may be insufficient; that understanding and quantitating the applied dose is fundamental to the interpretation of data and conclusions from each study; and that whole smoke/aerosol approaches must be contextualised with regard to key information, including appropriate experimental controls, environmental conditioning, analytical monitoring, verification and performance criteria.

Abstract
Coronavirus disease 2019 (COVID-19) was thought to have respiratory symptoms as the main manifestation, but it has become clear that extrapulmonary symptoms such as gastrointestinal disorders also occur. There are several reports of intussusception associated with COVID-19 in children, but these are rare in adults. In this report, we present a case of cystic intestinal duplication that enlarged during the course of COVID-19 treatment and resulted in intussusception. Right hemicolectomy was performed for intussusception due to the cystic lesion. To the best of our knowledge, this is the first resected case of intussusception due to alimentary tract duplication after COVID-19 infection.

Abstract
Introduction: Insulin is synthesized in the β-cells from preproinsulin. Preproinsulin
becomes proinsulin after leaving the signal peptide. Proinsulin is separated
into C-peptide and insulin by 2 enzymes. Hyperproinsulinemia is suspected to
be a pancreatic β-cell defect that is augmented by the increased demand
placed on the β-cell by hyperglycemia. Case presentation: A 39-year-old Japanese man visited to Shin-suma hospital in May 2013. Liver
dysfunction, dyslipidemia, and hyperuricemia had been found in medical
checkups in his workplace. Therefore, he visited Shin-suma hospital in order
to receive intensive examination. Diet and exercise therapy were initiated.
In November 2013, intact proinsulin and proinsulin per insulin (PI/I) ratio
were evaluated as part of an ongoing study. His intact proinsulin level and
PI/I ratio were markedly elevated. A 75 g oral OGTT revealed that his
glucose tolerance was impaired. His glycosylated hemoglobin was 6.9%. He was
diagnosed as having type 2 diabetes mellitus. Although, diet and exercise
therapy continued, his hyperproinslinemia and diabetes mellitus remained.
Therefore, aloguliptin was started in order to recover insulin secretion in
November 2014. Thereafter, pioglitazone was added to improve insulin
resistance. Finally, luseogliflozin was commenced to expect glucose-lowering
effects. His HbA1c was stabilized. To the best of our knowledge, there have
been few reports of patients with hyperproinsulinemia. Conclusion: When the physicians face treatment resistance in diabetes mellitus, we
emphasize that evaluation of proinsulin should be considered as one of the
methods.

Abstract
During a Cooperation Centre for Scientific Research Relative to Tobacco (CORESTA) meeting, the in vitro toxicity testing Sub-Group (IVT SG) met to discuss the evolving field of aerosol exposure research. Given the diversity of exposure parameters and biological endpoints being used, it was considered a high priority to investigate and contextualise the responses obtained. This is particularly driven by the inability to compare between studies on different exposure systems due to user preferences and protocol differences. Twelve global tobacco and contract research companies met to discuss this topic and formulate an aligned approach on how this diverging field of research could be appropriately compared. Something that is becoming increasingly important, especially in the light of more focused regulatory scrutiny. A detailed and comprehensive survey was conducted on over 40 parameters ranging from aerosol generation, dilution and data analysis across eight geographically independent laboratories. The survey results emphasise the diversity of in vitro exposure parameters and methodologies employed across the IVT SG and highlighted pockets of harmonisation. For example, many of the biological protocol parameters are consistent across the Sub-Group. However, variables such as cell type and exposure time remain largely inconsistent. The next steps for this work will be to map parameters and system data against biological findings and investigate whether the observed inconsistencies translate into increased biological variability. The results from the survey provide improved awareness of parameters and nuances, that may be of substantial benefit to scientists in intersecting fields and in the development of harmonised approaches.

Abstract
OBJECTIVES We previously reported the therapeutic potential of Bifidobacterium breve A1 (B. breve A1) for preventing cognitive impairment in Alzheimer's disease model mice, which suggested that supplementation of the probiotics could be an effective therapeutic strategy for managing cognitive function in mild cognitive impairment (MCI). DESIGN AND SETTINGS We conducted an open-label, single-arm study to examine the effects of 24-week supplementation of B. breve A1 on elderly with MCI in Aki Orthopedics Rehabilitation Clinic in Japan. PARTICIPANTS 27 participants were screened by their Mini Mental State Examination (MMSE) scores. MEASUREMENTS Cognitive function was assessed using MMSE and Digit Symbol Substitution Test (DSST) at baseline and every 8 weeks. Mental condition and quality of life for gastrointestinal symptoms were measured using the Profile of Mood States 2nd Edition (POMS2), and the Gastrointestinal Symptom Rating Scale (GSRS). RESULTS Of the 27 participants enrolled, 19 completed the study. MMSE scores were significantly increased during the intervention by mixed model Dunnett's test and Wilcoxon signed-rank tests (+1.7, P < 0.01). POMS2 and GSRS scores were significantly improved during intervention when analyzed by Wilcoxon signed-rank tests. CONCLUSION The present study showed that oral supplementation of B. breve A1 in participants with MCI improved cognitive function, thus suggesting the potential of B. breve A1 for improving cognitive function and maintaining quality of life of the elderly. Further randomized, double-blind placebo-controlled studies are worth conducting to examine the beneficial effect of B. breve A1.

Abstract
BACKGROUND Acral melanoma (AM) is an epidemiologically and molecularly distinct entity that is underrepresented in clinical trials on immunotherapy in melanoma. We aimed to analyze the efficacy of anti-programmed cell death 1 (anti-PD-1) antibodies in advanced AM. PATIENTS AND METHODS We retrospectively evaluated unresectable stage III or stage IV AM patients treated with an anti-PD-1 antibody in any line at 21 Japanese institutions between 2014 and 2018. The clinicobiologic characteristics, objective response rate (ORR, RECIST), survival estimated using Kaplan-Meier analysis, and toxicity (Common Terminology Criteria for Adverse Events 4.0.) were analyzed to estimate the efficacy of the anti-PD-1 antibodies. RESULTS In total, 193 patients (nail apparatus, 70; palm and sole, 123) were included in the study. Anti-PD-1 antibody was used as first-line therapy in 143 patients (74.1%). Baseline lactate dehydrogenase (LDH) was within the normal concentration in 102 patients (52.8%). The ORR of all patients was 16.6% (complete response, 3.1%; partial response, 13.5%), and the median overall survival (OS) was 18.1 months. Normal LDH concentrations showed a significantly stronger association with better OS than abnormal concentrations (median OS 24.9 versus 10.7 months; P < 0.001). Although baseline characteristics were similar between the nail apparatus and the palm and sole groups, ORR was significantly lower in the nail apparatus group [6/70 patients (8.6%) versus 26/123 patients (21.1%); P = 0.026]. Moreover, the median OS in this group was significantly poorer (12.8 versus 22.3 months; P = 0.03). CONCLUSIONS Anti-PD-1 antibodies have limited efficacy in AM patients. Notably, patients with nail apparatus melanoma had poorer response and survival, making nail apparatus melanoma a strong candidate for further research on the efficacy of novel combination therapies with immune checkpoint inhibitors.

Abstract
Although adipocytes are major targets of insulin, the influence of impaired insulin action in adipocytes on metabolic homeostasis remains unclear. We here show that adipocyte-specific PDK1 (3'-phosphoinositide-dependent kinase 1)-deficient (A-PDK1KO) mice manifest impaired metabolic actions of insulin in adipose tissue and reduction of adipose tissue mass. A-PDK1KO mice developed insulin resistance, glucose intolerance, and hepatic steatosis, and this phenotype was suppressed by additional ablation of FoxO1 specifically in adipocytes (A-PDK1/FoxO1KO mice) without an effect on adipose tissue mass. Neither circulating levels of adiponectin and leptin nor inflammatory markers in adipose tissue differed between A-PDK1KO and A-PDK1/FoxO1KO mice. Lipidomics and microarray analyses revealed that leukotriene B4 (LTB4) levels in plasma and in adipose tissue as well as the expression of 5-lipoxygenase (5-LO) in adipose tissue were increased and restored in A-PDK1KO mice and A-PDK1/FoxO1KO mice, respectively. Genetic deletion of the LTB4 receptor BLT1 as well as pharmacological intervention to 5-LO or BLT1 ameliorated insulin resistance in A-PDK1KO mice. Furthermore, insulin was found to inhibit LTB4 production through down-regulation of 5-LO expression via the PDK1-FoxO1 pathway in isolated adipocytes. Our results indicate that insulin signaling in adipocytes negatively regulates the production of LTB4 via the PDK1-FoxO1 pathway and thereby maintains systemic insulin sensitivity.

Abstract
BACKGROUND Taxanes are the current first-line treatment for advanced cutaneous angiosarcoma (CAS) for patients who are considered difficult to treat with doxorubicin owing to advanced age or comorbidity. However, no effective second-line therapy for such patients has been established. METHODS We designed a single-arm prospective observational study of eribulin mesylate (ERB) administered at a dose of 1·4 mg m-2 on days 1 and 8 in a 21-day cycle. Patients with advanced CAS who were previously treated with a taxane and were scheduled to begin ERB treatment were enrolled. The primary endpoint was overall survival (OS) and the secondary endpoints were response rate (RR), progression-free survival (PFS) and toxicity assessment. RESULTS We enrolled a total of 25 patients. The median OS and PFS were 8·6 months and 3·0 months, respectively. The best overall RR was 20% (five of 25). In total, 16 grade 3/4 severe adverse events (SAEs) occurred; however, all patients recovered. Patients who achieved partial response or stable disease as best response had longer OS than those with progressive disease (median OS not reached and 3·3 months, respectively; P < 0·001). Patients who did not experience SAEs showed longer OS than those who did (median OS 18·8 months and 7·5 months, respectively; P < 0·05). Patients with distant metastasis had shorter median OS than those with locoregional disease, but without statistically significant difference. CONCLUSIONS ERB showed a promising RR and is a potential candidate for second-line treatment for patients with CAS, after treatment with taxanes. However, owing to the occurrence of SAEs in over half of the participants, caution should be exercised regarding ERB use in elderly patients. What is already known about this topic? Taxanes are the current first-line treatment for patients with advanced cutaneous angiosarcoma (CAS) who are considered difficult to treat with doxorubicin owing to advanced age or comorbidity. No effective therapy for taxane-resistant CAS has been established thus far. Eribulin suppresses microtubule polymerization and elicits an antitumour effect similar to that of taxanes. What does this study add? In our single-arm prospective observational study to evaluate the efficacy of eribulin for treating patients with advanced CAS who previously received taxanes, the median overall survival and progression-free survival were 8·6 and 3·0 months, respectively. Response rates at weeks 7, 13 and 25 were 20%, 17% and 14%, respectively. Although 16 grade 3/4 severe adverse events occurred, all patients recovered. Eribulin showed a promising response rate and is a potential candidate for second-line treatment in CAS after taxane treatment. Linked Comment: Smrke and Benson. Br J Dermatol 2020; 183:797-798.

Abstract
HbA1c values in variant hemoglobin with a mutation on α chain and β chain are assumed to be different because the α chain and β chain of the globin gene have two and one gene(s), respectively. We examined whether the differentiation between HbA1c values in variant hemoglobin with a mutation on α chain (C1α) and β chain (C1β) is possible. Three patients with C1α and 9 patients with C1β were included. HbA1c was measured by standard mode high-performance liquid chromatography (HPLC) (HPLC-HbA1c) and immunoassay (IA: IA-HbA1c). Glycated albumin (GA) was determined, and each ratio was compared. HbA1c is expressed in National Glycohemoglobin Standardization Program (NGSP) units (A1C) and International Federation of Clinical Chemistry and Laboratory Medicine (IFCC) units (iA1c). Both the HPLC-A1C/IA-A1C ratio and the HPLC-iA1c/IA-iA1c ratio in C1α were significantly lower than those in C1β. Although there were no significant differences between the GA/HPLC-A1C ratios in both groups, the GA/HPLC-iA1c ratio in C1α was significantly higher than those in C1β. If the cutoff values for the HPLC/IA-iA1c ratio and GA/HPLC-iA1c ratio were set at 65% and 5.3, respectively, both sensitivity and specificity were 100%. Differentiation between C1α and C1β might be possible by using the HPLC-iA1c/IA-iA1c ratio or GA/HPLC-iA1c ratio.

Abstract
In vitro testing can facilitate the rapid assessment of next generation nicotine delivery products (NGPs) with comparisons to combustible tobacco products. In vitro assays for cytotoxicity and oxidative stress were employed at BAT (UK) and JT (Japan) to test total particulate matter (TPM) of a scientific reference cigarette and aerosol collected mass (ACM) of a commercially available E-cigarette and two tobacco heating products (THP). 3R4F TPMs were generated using the Health Canada intense (HCI) regimen, a modified regime (mHCI) for the THP ACMs and the CORESTA recommended method no. 81 for the E-cigarette ACM. Human lung cells were exposed to the test product TPM/ACMs at concentrations between 0-200 μg/ml followed by the employment of commercially available assays for endpoint analysis that included reactive oxygen species (ROS) generation, the glutathione ratio (GSH:GSSG), activation of the antioxidant response elements (ARE) and cellular viability. TPM/ACM nicotine concentrations were quantified using a UPLC-PDA technique. At both laboratories the 3R4F TPM induced significant and dose-dependent responses in all in vitro assays, whereas no significant responses could be measured for the NGP ACMs. In conclusion, both laboratories obtained comparable results across all endpoints therefore demonstrating the utility of the in vitro techniques combined with standardised test products to support the assessment of NGPs.

Abstract
SummaryAdenosine was rapidly incorporated into human platelets, and the inhibitory effect of adenosine on platelet aggregation was correlated with the incorporation process. Adenosine potentiated the inhibitory action of other inhibitors, such as dipyridamole, prostaglandin E1 and Y-3642. The inhibition of aggregation was associated with the preservation of platelet adenine nucleotides and the prevention of ADP release. On the other hand, the radioactive adenine nucleotide pattern of platelets was not substantially affected by inhibitors. The relation of inhibition of aggregation with ADP release was discussed.

Abstract
BACKGROUND Neuroendocrine tumors (NETs) of the gallbladder are rare and generally considered low-grade malignancies. We herein describe a case of a patient with a 0.8-cm clear cell NET G1 of the gallbladder with nodal involvement. CASE PRESENTATION A 65-year-old man with no medical history indicative of von Hippel-Lindau (VHL) disease underwent laparoscopic cholecystectomy for cholecystolithiasis. There was a 0.8-cm tumor in the neck of the gallbladder. Histologic examination revealed nests or trabecular growth of clear cells with small round-to-oval nuclei. Immunohistochemically, tumor cells showed positivity for chromogranin A and synaptophysin; Ki-67 index was < 1.0%. Based on the World Health Organization 2010 classification, we made a diagnosis of clear cell variant of NET G1 without VHL disease. The tumor invaded the muscular layer and had no extension to the perimuscular connective tissue but had metastasized to a cystic duct node. A radical second resection with regional lymphadenectomy of the gallbladder was performed, and there was no metastasis on histology. After the definitive surgery, he was followed up for 10 months without adjuvant therapy and is alive and well with no evidence of recurrence. CONCLUSIONS Our experience suggests that, even when smaller than 1 cm, NET G1 of the gallbladder can metastasize. When NET G1 is incidentally identified in the gallbladder of a surgical specimen, detailed pathologic examination of the cystic duct node, when found, should be performed to guide whether a radical second resection with regional lymphadenectomy is appropriate.

Abstract
SummaryObjectives: The aim of this study is to present a method of assessing psychological tension that is optimized to every individual on the basis of the heart rate variability (HRV) data which, to eliminate the influence of the inter-individual variability, are measured in a long time period during daily life.Methods: HRV and body accelerations were recorded from nine normal subjects for two months of normal daily life. Fourteen HRV indices were calculated with the HRV data at 512 seconds prior to the time of every mental tension level report. Data to be analyzed were limited to those with body accelerations of 30 mG (0.294 m/s2) and lower. Further, the differences from the reference values in the same time zone were calculated with both the mental tension score (Δtension) and HRV index values (ΔHRVI). The multiple linear regression model that estimates Δtension from the scores for principal components of ΔHRVI were then constructed for each individual. The data were divided into training data set and test data set in accordance with the twofold cross validation method. Multiple linear regression coefficients were determined using the training data set, and with the optimized model its generalization capability was checked using the test data set.Results: The subjects’ mean Pearson correlation coefficient was 0.52 with the training data set and 0.40 with the test data set. The subjects’ mean coefficient of determination was 0.28 with the training data set and 0.11 with the test data set.Conclusion: We proposed a method of assessing psychological tension that is optimized to every individual based on HRV data measured over a long period of daily life.

Abstract
A 64-year-old man was admitted to our hospital because of epigastralgia. Gastrointestinal endoscopyrevealed a submucosal tumor with ulceration in the upper bodyof the stomach. The tumor was histologicallydiagnosed as a neuroendocrine carcinoma. CT showed that the tumor had directlyinfiltrated the pancreas and splenic vessels. The patient underwent onlyan exploratorylaparotomybecause the tumor seemed to involve the celiac artery. Chemotherapywas conducted using CPT-11/ CDDP. After 15 courses of chemotherapy, a significant tumor reduction was obtained. We performed total gastrectomy with D2 lymphadenectomy, distal pancreatectomy and splenectomy. Histopathological examination of surgical specimens showed that onlyfew carcinoma cells remained in the stomach and pancreas. Neoadjuvant chemotherapycan be a useful treatment for unresectable locallyadvanced neuroendocrine carcinoma of the stomach.

Abstract
AIM We investigated which is the stronger predictor, pathological response or metabolic response, for survival outcome in patients treated with neoadjuvant chemoradiotherapy (NACRT) plus esophagectomy for thoracic esophageal squamous cell carcinoma (TESCC). PATIENTS AND METHODS Fifty consecutive patients with cStage IIB-IV TESCC were enrolled. We analyzed the pathological response and metabolic response (fractional decrease in tumor maximum standardized uptake value) to NACRT. Independent prognostic factors predictive of 3-year survival were investigated using univariate and multivariate analyses. RESULTS Among the 50 patients, 10 (20%) showed a pathological complete response (in both tumor and lymph nodes) and 36 (72%) showed grade 2-3 pathological response. Univariate analysis showed that age, gender, cT stage, pathological response and metabolic response to be significant prognostic factors. A subsequent multivariate analysis confirmed metabolic response and gender to be significant prognostic factors. CONCLUSION Metabolic response for NACRT was an independent prognostic factor and a more powerful predictor of survival compared to pathological response.

Abstract
Introduction: Patients with traumatic intracranial hemorrhage (ICH) or skull fracture are typically admitted to the Department of Neurosurgery for fear of delayed neurological deterioration. Neurosurgeons, therefore, must be careful not to overlook a spinal fracture in these patients. In this study, we investigated the occurrence and risk factor of spinal fracture in patients with traumatic ICH or skull fracture. Patients and methods: We retrospectively analyzed the hospital records of 134 patients admitted to the Department of Neurosurgery at Kagawa Rosai Hospital for traumatic ICH or skull fracture. The etiology of trauma, level of consciousness, presence or absence of ICH, skull fracture, craniotomy and spinal surgery were investigated. Furthermore, in cases of spinal fracture, its type, neurological symptoms, treatment were investigated. Results: In an analysis of 134 patients, Ground level fall and traffic accident were the most frequent etiologies of trauma (47.0% and 23.9% respectively). Glasgow coma scale on admission was 15-13 for 106 patients (79.1%). spinal fracture was identified in 10 of 134 patients (7.5%). Two patients had cervical, 8 had thoracolumbar fractures. In the analysis of risk factors, an accidental fall and skull fracture was observed significantly more in the spinal fracture cases. Conclusion: The majority of traumatic ICH or skull fracture cases treated in the Department of Neurosurgery were caused by minor head impacts. When treating these patients, it is necessary to investigate not only the cervical, but also the thoracolumbar spine, especially when the cause of injury is an accidental fall and a skull fracture is identified.

Abstract
BACKGROUND/AIM Programmed death-1 ligand 1 (PD-L1) induces apoptosis of tumor-reactive T-cells, that enables tumors to evade immune defense and thus furthers their growth. Our aim was to determine whether PD-L1 expression status correlates with prognosis in patients with advanced thoracic esophageal squamous cell carcinoma. PATIENTS AND METHODS The PD-L1 expression status of 177 patients treated with esophagectomy without preoperative therapy was evaluated immunohistochemically using tissue microarray. We then statistically analyzed the relationships between PD-L1 expression status and clinicopathological features and survival. RESULTS In patients undergoing surgery alone, PD-L1 expression was significantly positivity associated with a better prognosis. By contrast, there were no significant correlations between PD-L1 expression and clinicopathological features or outcomes in patients treated with surgery plus postoperative adjuvant chemotherapy. CONCLUSION PD-L1 positivity in advanced thoracic esophageal squamous cell carcinoma may be predictive of a positive prognosis in patients treated without adjuvant chemotherapy.

Abstract
A 77-year-old woman with rectal cancer and synchronous liver metastasis underwent a Hartmann operation with D3 lymph node dissection in June 2014. mFOLFOX6 plus bevacizumab(bev)was then administered to treat the liver metastasis.In February 2015, multiple liver metastases were detected and the regimen was changed to FOLFIRI plus bev.After 3 courses, peritonitis due to intestinal perforation around the descending colostomy occurred, and an emergency operation(partial resection of the descending colon and transverse colostomy)was performed.FOLFIRI was then administered from 2 months after the operation.After 3 courses of this regimen, a CT scan showed progression of the hepatic metastases.The regimen was therefore changed to mFOLFOX6.Five months later, another CT scan showed an intestinal perforation of the transverse colostomy at the abdominal wall, and an emergency cecostomy was performed.At this stage, chemotherapy was ceased.This case highlights the risk of intestinal perforation during chemotherapy, regardless of the use of bev.

Abstract
An 82-year-old man with upper abdominal pain was referred to our hospital because of an elevated serum CEA level and dilatation of the intrahepatic bile ducts on ultrasonography.Computed tomography revealed a hypovascular mass measuring 5.0 cm in size in the lateral section, dilatation of the peripheral intrahepatic bile ducts, and swollen lymph nodes around the lesser curvature of the stomach, the common hepatic artery, and the paraaorta.He was diagnosed with unresectable intrahepatic cholangiocarcinoma, and he received chemotherapy with biweekly gemcitabine plus cisplatin.After 33 courses of the chemotherapy, computed tomography revealed that the tumor size decreased over 63%, and all swollen lymph nodes had almost resolved.He underwent a left hemihepatectomy 1 year 6 months after the start of the chemotherapy.He remains alive and well with no evidence of recurrence, 11 months after resection.

Abstract
BACKGROUND Poor oral health is a risk factor for causing upper aerodigestive tract tumors, including esophageal cancer. Our aim was to determine the periodontitis rate in our cohort of esophageal cancer patients. We also analyzed whether preoperative dental examination and care reduces the likelihood of severe pneumonia after esophagectomy. STUDY DESIGN Between 2003 and 2014, 529 esophageal cancer patients received esophagectomy at Akita University Hospital. We studied 232 patients who had preoperative dental examinations and care (dental care group) retrospectively and assessed the severity of their periodontitis. The dental care group was compared to 297 patients who did not have preoperative dental care (control group) with respect to the incidence of severe pneumonia after esophagectomy. RESULTS Ninety-one patients (39.2%) in the dental care group were diagnosed with slight periodontitis and 69 (29.7%) were diagnosed with severe periodontitis. Among all the patients, 69 patients (13.0%) were diagnosed with grade 3B postoperative severe pneumonia. The dental care group had a significantly lower incidence of severe pneumonia than the control group. Moreover, multivariable logistic regression analysis revealed that anastomotic leakage, preoperative dental care, gender and %VC were correlated significantly with the occurrence of postoperative severe pneumonia. CONCLUSION Preoperative dental examination and care by a dentist are essential to reduce the likelihood of postoperative severe pneumonia in esophageal cancer patients.

Abstract
Mediastinal aneurysms are rare but potentially life-threatening. Among these, bronchial artery aneurysms are most frequently reported, whereas up to now aneurysms of the proper esophageal artery had never been reported. A 69-year-old woman was referred to our hospital for treatment of a massive mediastinal hematoma. Enhanced computed tomography and selective proper esophageal arteriography revealed a 5-mm aneurysm in the proper esophageal artery that arises from the thoracic aorta at the Th8 level and has an anastomotic branch with the bronchial artery peripherally. Transcatheter arterial embolization was successfully performed using a mixture of N-butyl cyanoacrylate and lipiodol (1:3 ratio, 0.3 ml). Post-embolization angiography showed no filling into the aneurysm. The patient recovered with no complications and was discharged on the 25th post-procedure day.

Abstract
BACKGROUND To examine the effect of the histology of carcinoma and sarcoma components on survival outcome of uterine carcinosarcoma. PATIENTS AND METHODS A multicenter retrospective study was conducted to examine uterine carcinosarcoma cases that underwent primary surgical staging. Archived slides were examined and histologic patterns were grouped based on carcinoma (low-grade versus high-grade) and sarcoma (homologous versus heterologous) components, correlating to clinico-pathological demographics and outcomes. RESULTS Among 1192 cases identified, 906 cases were evaluated for histologic patterns (carcinoma/sarcoma) with high-grade/homologous (40.8%) being the most common type followed by high-grade/heterologous (30.9%), low-grade/homologous (18.0%), and low-grade/heterologous (10.3%). On multivariate analysis, high-grade/heterologous (5-year rate, 34.0%, P = 0.024) and high-grade/homologous (45.8%, P = 0.017) but not low-grade/heterologous (50.6%, P = 0.089) were independently associated with decreased progression-free survival (PFS) compared with low-grade/homologous (60.3%). In addition, older age, residual disease at surgery, large tumor, sarcoma dominance, deep myometrial invasion, lymphovascular space invasion, and advanced-stage disease were independently associated with decreased PFS (all, P < 0.01). Both postoperative chemotherapy (5-year rates, 48.6% versus 39.0%, P < 0.001) and radiotherapy (50.1% versus 44.1%, P = 0.007) were significantly associated with improved PFS in univariate analysis. However, on multivariate analysis, only postoperative chemotherapy remained an independent predictor for improved PFS [hazard ratio (HR) 0.34, 95% confidence interval (CI) 0.27-0.43, P < 0.001]. On univariate analysis, significant treatment benefits for PFS were seen with ifosfamide for low-grade carcinoma (82.0% versus 49.8%, P = 0.001), platinum for high-grade carcinoma (46.9% versus 32.4%, P = 0.034) and homologous sarcoma (53.1% versus 38.2%, P = 0.017), and anthracycline for heterologous sarcoma (66.2% versus 39.3%, P = 0.005). Conversely, platinum, taxane, and anthracycline for low-grade carcinoma, and anthracycline for homologous sarcoma had no effect on PFS compared with non-chemotherapy group (all, P > 0.05). On multivariate analysis, ifosfamide for low-grade/homologous (HR 0.21, 95% CI 0.07-0.63, P = 0.005), platinum for high-grade/homologous (HR 0.36, 95% CI 0.22-0.60, P < 0.001), and anthracycline for high-grade/heterologous (HR 0.30, 95% CI 0.14-0.62, P = 0.001) remained independent predictors for improved PFS. Analyses of 1096 metastatic sites showed that carcinoma components tended to spread lymphatically, while sarcoma components tended to spread loco-regionally (P < 0.001). CONCLUSION Characterization of histologic pattern provides valuable information in the management of uterine carcinosarcoma.

Abstract
BACKGROUND The influence of adenomyomectomy on subsequent pregnancy is unknown. Placenta accreta is most often associated with placenta previa in women with multiple previous cesarean sections. CASE A 41-year-old woman became pregnant six years after a laparoscopic uterine posterior adenomyomectomy. She was diagnosed with complete placenta previa and considered at a low risk for placenta accreta by ultrasonography. Cesarean section and subsequent hysterectomy were required, and histopathological analysis revealed a posterior placenta accreta. DISCUSSION The authors discuss the association of adenomyomectomy and placenta accreta on subsequent pregnancy and conclude that previous adenomyomectomy may increase the risk of abnormal placentation. Therefore, careful treatment is required during the pregnancies of patients with previous adenomyomectomy.

Abstract
PURPOSE To present a case report on the successful management of a low-lying placenta and aplastic anemia. Aplastic anemia is a rare but serious disorder that is often characterized by severe pancytopenia. Because of the rarity of aplastic anemia, a pregnancy complicated by it is rarely encountered by obstetricians. Moreover, placenta previa (low-lying placenta) complicated by aplastic anemia has not been previously reported. MATERIALS AND METHODS The authors present the first reported case of placenta previa with aplastic anemia in a patient who had undergone a previous cesarean delivery. RESULTS They successfully managed this case by making a transverse uterine fundal incision during an elective cesarean delivery. This incision minimized blood loss and enabled good visualization of the source of bleeding in the lower uterine segment. Bleeding was stemmed by suturing the source of bleeding. CONCLUSION The authors propose that this procedure should be considered for patients with low platelet counts and abnormal placentation.
