Abstract
Introduction Anastomotic leakage is a serious complication in colon and rectal cancer surgeries, contributing to increased mortality rates and extended hospital stays. Despite various preventive measures, including intraoperative assessments and transanal drains, the incidence of anastomotic leakage remains a significant concern. This study investigates the potential efficacy of polyglycolic acid (PGA) sheets in reducing anastomotic leakage rates in gastrointestinal surgeries. Materials & methods A retrospective cohort study was conducted between January 2021 and January 2023 at Nagoya Tokushukai General Hospital, Ogaki Tokushukai Hospital, and Haibara General Hospital. A total of 239 patients undergoing colon or rectal cancer surgery were included. Anastomoses were performed with or without PGA sheets, and groups were compared using statistical analyses, including t-tests, Mann-Whitney U tests, and chi-square tests. The primary endpoint was the incidence of anastomotic leakage. Results Of the 239 patients, anastomotic leakage occurred in 14 (6%). The PGA use group (52 patients) showed no instances of anastomotic leakage while the PGA non-use group (187 patients) had 14 cases. Comparisons revealed significant differences in anastomotic leakage rates (p=0.04) between the two groups. Univariate analysis demonstrated a lower incidence of anastomotic leakage associated with PGA use (p=0.04). However, no significant differences were observed for transanal drainage (p=0.66), smoking (p=0.76), steroid use (p=1), and preoperative chemotherapy (p=0.07). Conclusion This study suggests that the use of PGA sheets in gastrointestinal anastomosis may contribute to a lower incidence of anastomotic leakage. The findings highlight the need for further prospective studies with a larger sample size, distinguishing between colon and rectum surgeries. Despite the limitations of this retrospective study, the observed reduction in anastomotic leakage frequency with PGA sheet use is noteworthy, emphasizing the potential significance of this approach in preventing a critical complication in colorectal surgeries.

Abstract
The patient was an 81-year-old man. After a liver posterior segmentectomy for hepatocellular carcinoma, a painful bulge was observed in the left anterior thoracic region during a routine outpatient visit. Elevated tumor markers and contrast- enhanced CT scan revealed a mass with contrast effect in the left 7th rib. Ultrasound-guided biopsy revealed hepatocellular carcinoma metastatic to the left 7th rib. There were no other obvious metastases, and the diagnosis of a single bone metastasis was made. The patient did not request chemotherapy and underwent transcatheter arterial chemoembolization 4 times. The patient did not show any improvement in tumor markers or shrinkage of the tumor, and his quality of life was deteriorated due to increased pain. The patient underwent left chest wall tumor resection and chest wall reconstruction. Postoperative tumor markers were normalized and pain improved markedly. We report a case of postoperative recurrence- free survival for 2 years.

Abstract
INTRODUCTION AND IMPORTANCE The treatment of multiple cancers requires multidisciplinary expertise. In this case, we experienced a multiple cancers case, sigmoid colon cancer and intrahepatic cholangiocarcinoma that required preoperative portal vein embolization (PVE). PVE is often approached by trans-hepatic percutaneous approach or via ileocecal vein (ICV) or veins of the small intestine. In this case, the patient was scheduled to undergo robot-assist surgery for sigmoid colon cancer, and it was planned that the inferior mesenteric vein (IMV) would be cut. PVE from the IMV was performed with hope to reduce complications. CASE PRESENTATION This patient had intrahepatic cholangiocarcinoma and sigmoid colon cancer. A radical cure for intrahepatic cholangiocarcinoma was expected by left liver lobectomy. Because of concerns about postoperative liver failure, it was decided to perform PVE. PVE via IMV approach was performed simultaneously with robot-assisted surgery for sigmoid colon cancer. The patient was discharged without complications 12 days after surgery. CLINICAL DISCUSSION PVE is a very important technique for massive hepatic resection. Percutaneous trans-hepatic approach has the potential to damage vessels, bile duct, normal liver. Venous approaches, including via ICV, have the potential to damage vessels. In this case, we performed PVE from the IMV because we thought this approach would reduce the risk of complications. The patient successfully underwent PVE without complications. CONCLUSION PVE via IMV was successfully performed without complications. In multiple cancers case, this approach would be better approach than any other PVE approach like this case.

Abstract
Introduction With the global pandemic of COVID-19 for over two years, we might have to proceed surgical operation of patients with COVID-19 infection because of its emergency. Here we present a case who received an emergency operation for an irreducible inguinal hernia with COVID-19. We safely performed trans-abdominal pre-peritoneal repair (TAPP) in one surgery without any problems. Presentation of case 52-year-old male with no specific past medical history came to the emergency department with complaints of right inguinal bulging and abdominal pain. On physical examination, a bulge in the right inguinal region was observed, so a right irreducible inguinal hernia was suspected. Since he had fever, we conducted a COVID-19 antigen test and it was positive. For we could not return with manually, and we decided to perform emergency surgery with appropriate infection control techniques. After laparoscopic return of the intestinal tract, a mesh was implanted using TAPP. The patient was discharged 2 days after surgery. Discussion Even in pandemic of COVID-19, cases of irreducible inguinal hernia could be occur. COVID-19 has systemic inflammation, so we worried about mesh infection. But this patient took TAPP safely in emergency surgery with COVID-19. Conclusion We experienced a case of TAPP proceeded patient with COVID-19. We considered that placement of a foreign material is acceptable when it is necessary in COVID-19 patient safely.

Abstract
BACKGROUND/AIM COVID-19 has been a global pandemic for more than 2 years, and vaccination against COVID-19 using an mRNA vaccine is widespread. The COVID-19 vaccination can cause specific side-effects, such as axillary lymph node swelling; therefore, breast oncologists should pay attention to such occurrences. Initially, only two COVID-19 vaccinations were planned; however, in some countries third or fourth vaccines have been administered. Here, we present a female case who developed axillary lymph node swelling after her third vaccination. We have also reviewed the literature regarding this side-effect after a third or fourth COVID-19 vaccination. CASE REPORT A 64-year-old woman who came to our clinic regarding a mammography abnormality in her left breast. She had no palpable mass, but a left breast mass was shown by mammography, and ultrasonography and magnetic resonance imaging indicated a hamartoma. At 2 months after her second COVID-19 vaccination when she underwent these tests, she had no axillary lymph node swelling. We planned a follow-up after 6 months. At her next visit, by chance, she underwent ultrasonography 14 days after she received a third COVID-19 vaccination, and a swollen axillary lymph node was observed. CONCLUSION Axillary lymph node swelling can occur after a third COVID-19 vaccination. Therefore, breast oncologists will have to consider this side-effect of COVID-19 vaccination when diagnosing breast tumors.

Abstract
BACKGROUND/AIM COVID-19 vaccination is now performed in most of the world to limit the spread of the disease. The first mRNA vaccine was approved in clinical settings and has specific side effects including axillary lymph node swelling, which can be misdiagnosed as breast cancer metastasis. The timing of axillary lymph node swelling and its duration are unclear. Here, we present a Japanese case and review of the existing literature. CASE REPORT We report the case of a 67-year-old woman with breast calcification. She had regular follow ups in our hospital for this calcification and received ultrasonography of the breast and axilla at every visit. She visited 6 months before having her COVID-19 vaccination, and 7 days and 6 months after the first COVID-19 vaccination. She had a swollen axillary lymph node 7 days after the first vaccination, which although it was improved, remained for 6 months. CONCLUSION Axillary lymph node swelling occurred 7 days after vaccination and remained up to 6 months after it.

Abstract
BACKGROUND/AIM COVID-19 started to spread as a pandemic in December 2019 and COVID-19 vaccination has been initiated worldwide. The efficacy of vaccination has been scientifically proven, but it might cause axillary lymph node swelling. To diagnose patients with axillary lymph node swelling caused by COVID-19 vaccination, we herein reviewed existing literature on this symptom. CASE REPORT We report the case of a 70-year-old woman with a breast tumour. She had undergone cecum cancer surgery and regular computed tomography (CT). During breast tumour follow-up, she received scheduled CT that indicated severe axillary lymph node swelling mimicking breast cancer metastasis. We performed aspiration biopsy cytology of that lymph node, and determined this was not cancer metastasis but an effect of the COVID-19 vaccine. We confirmed this diagnosis at one month after computed tomography showed that the lymph node swelling had improved. CONCLUSION Axillary lymph node swelling can occur after COVID-19 vaccination. Therefore, it is important to consider the effect of the COVID-19 vaccination on axillary lymph node swelling when diagnosing breast tumours.

Abstract
An 85-year-old man underwent thoracic endovascular aortic repair (TEVAR) for a thoracic aortic aneurysm (TAA). The day after TEVAR, the patient complained of abdominal pain. Blood tests showed lactic acidosis. Contrast-enhanced CT of the abdomen showed emphysema and poor contrast areas in the lower esophagus, total stomach, and duodenum. The left lobe of the liver also showed a poorly contrasted area. Indocyanine green (ICG) intraoperative blood flow evaluation was performed by laparoscopy to evaluate how organ ischemia is and whether resection of necrotic organs is possible. It was judged that resection of the poor perfusion area would not improve prognosis because of the extensive area of poor perfusion in the ICG intraoperative perfusion evaluation. In TEVAR for TAA, embolization of the celiac artery (CA) can be performed if collateral blood flow is demonstrated. However, in this case, extensive organ necrosis happened. We discuss the cause of this case and the usefulness of ICG intraoperative blood flow assessment when ischemia is suspected.

Abstract
Information on the biodistribution (BD) of cell therapy products (CTPs) is essential for prediction and assessment of their efficacy and toxicity profiles in non-clinical and clinical studies. To conduct BD studies, it is necessary to understand regulatory requirements, implementation status, and analytical methods. This review aimed at surveying international and Japanese trends concerning the BD study for CTPs and the following subjects were investigated, which were considered particularly important: 1) comparison of guidelines to understand the regulatory status of BD studies in a global setting; 2) case studies of the BD study using databases to understand its current status in cell therapy; 3) case studies on quantitative polymerase chain reaction (qPCR) used primarily in non-clinical BD studies for CTPs; and 4) survey of imaging methods used for non-clinical and clinical BD studies. The results in this review will be a useful resource for implementing BD studies.

Abstract
Introduction We report a case of a patient who underwent laparoscopic surgery for intestinal obstruction caused by the mesodiverticular band of Meckel's diverticulum, with pathological specimens showing ectopic pancreas. Presentation of case A 56-year-old woman presented to our hospital with complaints of abdominal pain and vomiting. Upon close examination, we suspected strangulated intestinal obstruction, and performed an emergency surgery. An internal hernia with a band leading to a Meckel's diverticulum was noted. Focusing on the attachment of the band, leading to the Meckel's diverticulum, we suspected a mesodiverticular band and deemed it necessary to be resected. Surgery was completed with resection of the band to relieve the intestinal obstruction, with simultaneous resection of the Meckel's diverticulum. It was necessary to resect Meckel's diverticulum simultaneously for histopathological examination. Histopathological examination revealed a mesodiverticular band in the resected band and ectopic pancreas in the Meckel's diverticulum. Discussion We chose to perform a complete laparoscopic resection because of the presence of simple intestinal obstruction caused by mesodiverticular bands or diverticula. We believe that small laparotomy can be opted in less severe cases, regardless of laparoscopic completion. Conclusion We suspected adherent bowel obstruction and detected a band. We focused on band attachment and determined that the band should be resected if it was attached to Meckel's diverticulum. The resection method should be carefully selected, and the specimen should be histopathalogically examined. We report a case of intestinal obstruction due to a mesodiverticular band. The resection method for Meckel's diverticulum should be carefully selected. Histopathological examination of the specimen should be performed. Small laparotomy can be opted for less severe cases.

Abstract
BACKGROUND/AIM Breast cancer treatment mainly involves interventional methods such as surgical resection and chemotherapy. How to best perform these treatments during the COVID-19 pandemic remains to be established. PATIENTS AND METHODS Patients with breast cancer who received SARS-CoV-2 PCR screening before cancer treatment from December 2020 to April 2021 were included. PCR screening was performed within 72 hours of the scheduled admission time and treatment. RESULTS A total of 19 tests in 15 patients were analysed. Fourteen cases displayed no symptoms, and five cases had some symptoms. COVID PCR tests were negative in all cases. CONCLUSION COVID-19 screening can ensure that breast cancer patients do not miss scheduled treatments as a result of the pandemic. Diagnosis of patients with symptoms that are shared by COVID-19 infection, chemotherapy, and breast cancer recurrence must be performed carefully.

Abstract
Abstract
Background/Introduction
Smoking is known to induce systemic vascular damage, leading to cardiovascular diseases. Recent studies demonstrated that central blood pressure has a greater impact on cardiovascular events than brachial blood pressure.
Purpose
We investigated influences of habitual smoking on central systolic blood pressure (CSBP) in hypertensive subjects.
Methods
A total of 5630 subjects (male = 2622, 51.7±12.0 year-old at baseline), who visited our hospital for a physical check-up at least twice during the last 10 years and underwent CSBP measurement at each visit, were enrolled, and they were divided into three groups; normotensive (n=4634), non-treated hypertensive (n=91) and treated hypertensive subjects (n=905). Then, the influences of smoking on the average and yearly changes of CSBP (median follow-up 5 years) were analyzed. Brachial blood pressure (oscillometer) and radial artery pressure waveforms (tonometer) were recorded using an automated device, and the pressure corresponding to the second systolic peak of radial pressure waveforms was taken as CSBP (HEM-9000AI, Omron Healthcare, Kyoto). Hypertension was defined as brachial BP ≥140/90mmHg or the use of antihypertensive medications. A yearly change in CSBP was calculated in each subject by linear regression analysis using longitudinal data.
Results
The average CSBP was higher in habitual smokers than in non-smokers when analyzed in normotensive (109.1±11.7 vs. 107.6±12.8 mmHg, p<0.001) and non-treated hypertensive subjects (150.7±14.8 vs. 142.8±16.7 mmHg, p<0.05), whereas in hypertensive subjects under medication the average CSBP was lower in smokers than in non-smokers (124.6±12.4 vs. 127.8±13.6 mmHg, p<0.01). Smoking status did not affect yearly changes of CSBP in normotensive (habitual smokers vs. non-smokers; 1.38±6.00 vs. 1.44±6.04 mmHg/year), treated hypertensive (−0.16±7.08 vs. −0.66±8.24 mmHg/year), and non-treated hypertensive subjects (4.09±15.1 vs. −0.53±10.3 mmHg/year).
Conclusions
Habitual smoking increases CSBP, however, antihypertensive medications counteract the unfavorable effects of smoking on CSBP. These results imply a new pathway underlying the development of cardiovascular diseases in smokers. Unfavorable changes in the cardiovascular system caused by smoking may quite slowly progress that short period of observation in the present study could not have detected enhanced yearly increases of CSBP by smoking.

Abstract
Abstract
Background/Introduction
Visit-to-visit blood pressure variability (BPV) is a strong predictor of cardiovascular events as well as target organ damage (TOD) in hypertension. However, effects of year-to-year BPV on the development of TOD have not been investigated in the general population.
Purpose
The present study was designed to investigate a possible relationship between year-to-year BPV and TOD in the general population.
Methods
Consecutive 5542 subjects (male=3771, 58.6±10.7 yea-old) who visited our hospital for an annual physical check-up for 5 years in a row during 2008 and 2013 were enrolled. The average, standard deviation (SD), coefficient of variation (CV), and average real variability (ARV) of systolic blood pressure (SBP) were calculated using data during the period. Other baseline data were obtained in 2013; left ventricular hypertrophy (LVH; Sokolow-Lyon voltage >3.8 mV and/or Cornell product >2440 mm ms) and kidney impairment (estimated glomerular filtration rate; eGFR<60) were taken as TOD. Then, subjects without TOD at baseline (2013) (n=3801, male=2584, 57.4±10.4 yea-old) were followed up until 2019 (median = 5 years) and the impact of BPV on the development of TOD was investigated.
Results
The average, SD, CV and ARV of SBP were 123.8 mmHg, 8.04 mmHg, 6.50%, and 9.19 mmHg, respectively. At baseline, these parameters were higher in subjects with TOD than those without TOD (Table 1-A). During the follow-up of subjects without TOD at baseline, LVH and kidney impairment developed in 425 and 623 subjects (24.7 and 35.8 per 1000 person-year), respectively. In retrospective analysis, the average, SD, and ARV were higher in subjects with than without future TOD (Table 1-B). Although some indices of year-to-year BPV predicted future development of TOD in univariate Cox-hazard analysis, only the average of SBP predicted incident TOD after adjustment.
Conclusions
Year-to-year BPV is a marker of the incident TOD in the general population. However, these indices do not independently predict the onset of TOD and, thus, there may be unknown pathway that links TOD and BPV.

Abstract
Hemorrhagic rupture is a very rare and life-threatening hepatic cyst complication. Several treatment methods have been used for hepatic cyst hemorrhage and/or rupture; however, transcatheter arterial embolization for hepatic cyst hemorrhage has been poorly documented. An 80-year-old man receiving dual antiplatelet therapy was diagnosed with hemorrhagic rupture of a hepatic cyst. Transcatheter arterial embolization using a coil was performed for A6 branch confirmed active extravasation. His condition improved promptly after treatment, and the hepatic cyst gradually became smaller as compared to the size before hemorrhage. Transcatheter arterial embolization is suitable for hepatic cyst hemorrhage and might be a minimally invasive treatment option for a symptomatic hepatic cyst.

Abstract
The anti-inflammatory effects of a 50% aqueous extract of Rosa roxburghii fruit (RRFE) and two ellagitannins (strictinin and casuarictin) isolated from the RRFE were evaluated in a cell model of skin inflammation induced by self-RNA released from epidermal cells damaged by UV ray (UVR) irradiation. The RRFE inhibited interleukin-8 (IL-8) mRNA expression in normal human epidermal keratinocytes (NHEKs) stimulated with polyinosinic:polycytidylic acid (poly(I:C)), a ligand of toll-like receptor-3 (TLR-3). The plant-derived anti-inflammatory agents, dipotassium glycyrrhizinate (GK2) and allantoin, had no influence on the IL-8 expression. The purified compounds, strictinin and casuarictin, inhibited the IL-8 mRNA expression and IL-8 release induced in NHEKs by poly(I:C). These ellagitannins were thus found to be responsible for the biological activity exhibited by the RRFE. This study demonstrates that RRFE and isolated RRFE compounds show promise as ingredients for products formulated to improve skin disorders induced by UVR irradiation.

Abstract
Abstract
Background/Introduction
The National Nutrition Survey in Japan indicated that dietary salt intake of the Japanese is gradually decreasing for the last several decades, while salt intakes are higher in elderly than young people. There is no survey on the alteration of salt intakes with advancing age in individuals.
Purpose
The present study investigated effects of aging on salt intakes in individuals.
Methods
A total of 2600 subjects (men; 1787, age; 30 to 79 years-old at 2008) who participated in our physical check-up program both in 2008 and 2018 were enrolled. Individual dietary salt intakes in 2008 and 2018, which were estimated using a spot urine by a previously reported method, were compared.
Results
The mean age and salt intakes at 2008 were 53.9±10.0 years and 12.2±3.2 g/day in men and 54.4±9.2 years and 8.3±2.1 g/day in women, respectively. Salt intake increased to 13.2±3.3 g/day in men and 8.8±2.2 g/day in women during the 10 years. Salt intakes were higher in hypertensive than normotensive subjects both at 2008 and 2018, but changes of blood pressure category were not associated with those of salt intakes during the 10 years (table). Changes in salt intakes in each decade are shown in Figure. Salt intakes in each decade increased with advancing age both in men and women until their 70s. Salt intakes in people in their 60s and 70s at 2018 were higher than those at 2008. Similar results were obtained in subjects without any anti-hypertensive medications (n=1667) (data not shown).
Conclusions
The observational follow-up study revealed that salt intakes in each individual increased after the interval of 10 years in both men and women. The results suggest that the sense of taste changes with advancing age in young adults as well as elderly persons, which may be related with alterations of lifestyle.

Abstract
Background/Introduction
Hypertension induces kidney dysfunction, and vice versa. Furthermore, kidney dysfunction can be a risk factor for cardiovascular diseases as well as end-stage of kidney disease. Although blood pressure (BP) control is necessary to prevent deterioration of kidney function, strict BP control may deteriorate kidney function.
Purpose
The present observational study investigated effects of BP levels on the incidence of chronic kidney disease (CKD) in the general population.
Methods
A total of 12,753 subjects with normal kidney function (estimated glomerular filtration rate [eGFR] ≥60 mL/min per 1.73 m2) (male 7,707, mean age 51.8 years) who visited our hospital for an annual physical check-up from April 2010 to March 2018 were enrolled. After baseline examination, subjects were followed up until March 2019 (median 1769 days) with the endpoint being the development of CKD (eGFR<60 mL/min per 1.73 m2). The modified MDRD formula for Japanese was used to calculate eGFR. Hypertension was defined as BP ≥140/90mmHg or the use of antihypertensive medication.
Results
During the follow-up period, 1,604 subjects developed CKD (26.9 per 1,000 person-years) with the incidence being more frequent in hypertensive (n=3,098) than normotensive (n=9,655) subjects at enrollment (44.2 vs. 21.5 per 1,000 person-years, respectively; hazard ratio [95% confidence interval] from multivariate Cox proportional analysis 1.205 [1.061–1.369]). Hazard ratio of systolic BP at baseline was 1.006 [1.002–1.010] in a multivariate Cox proportional hazard regression model adjusted for possible risk factors. The incidence was lower in subjects without hypertension throughout the follow-up period (normotension group, n=7,866) than those who were diagnosed as having hypertension at least once during the period (hypertension group, n=4,887) (23.1 vs. 32.3 per 1,000 person-years, p<0.001). In the normotension group, subjects with average BP <120/80mmHg had lower incidence of CKD than in those with BP ≥120/80mmHg (17.2 vs. 36.1 per 1,000 person-years, p<0.001). In contrast, in the hypertension group, the incidences of CKD in subjects with average BP <120/80, 120–139/80–89 and ≥140/90mmHg were 34.3, 25.8, and 54.4 per 1,000 person-years, respectively (p<0.001). Moreover, in hypertensive subjects under medication (n=2,002) with average BP <120/80, 120–139/80–89 and ≥140/90mmHg, the incidence of CKD was 65.5, 41.3, and 64.3 per 1,000 person-years, respectively (p<0.01).
Conclusions
The incidence of CKD was higher in hypertensive than in normotensive subjects. The lower BP was associated with the lower incidence of CKD in normotensive subjects, while strict BP control may increase the risk of CKD in hypertensive subjects.

Abstract
Abstract
Background/Introduction
Dietary salt consumption is one of the most important modifiable factors in our lifestyle and restriction of dietary salt results in the reduction of blood pressure in previous studies. Excessive salt intake causes cardiovascular diseases independently of its effects on blood pressure. Since metabolic syndrome also increases a risk of cardiovascular disease, there may be some association between salt intake and metabolic syndrome.
Purpose
The present study was designed to investigate a possible relationship between salt intake and future development of metabolic syndrome in the general population.

Consecutive 12,256 subjects without metabolic syndrome (male=7,053, 52.1±12.3 year-old) who visited our hospital for an annual physical check-up from April 2010 to March 2018 were enrolled. After baseline examination, subjects were followed up until March 2019 (median 1,582 days) with the endpoint being the development of metabolic syndrome. Metabolic syndrome was diagnosed according to the Japanese criteria (2005). Individual salt intake was estimated using a spot urine by a previously reported method.
Results
Salt intake was 11.9±3.0 g/day in male and 8.2±2.1 g/day in female subjects at baseline. During the follow-up period, 1,669 subjects developed metabolic syndrome (29.9 per 1,000 person-year) with the incidence being more frequent in male than female subjects (41.8 vs. 14.2 per 1,000 person-year). Non-adjusted hazard ratio (HR) (95% confidence interval [CI]) of salt intake for the development of metabolic syndrome was 1.157 (1.142–1.173). In analysis where subjects were divided into gender-specific quartiles according to the baseline salt intake, Kaplan-Meyer curve analysis revealed that the incidence of metabolic syndrome were increased across the quartiles (20.6, 25.0, 32.4, and 42.7 per 1,000 person-years; logrank p<0.001). Multivariate Cox proportional hazard analysis adjusted for age, gender, body mass index, systolic blood pressure, heart rate, serum creatinine, uric acid, fasting plasma glucose, low-density lipoprotein cholesterol, triglyceride, hemoglobin and current smoking habit at baseline revealed that salt intake predicted the new onset of metabolic syndrome (HR: 1.036, 95% CI: 1.019–1.054).
Conclusions
Excessive salt intake is significantly associated with the new development of metabolic syndrome in the general population. The results suggest that salt restriction prevents metabolic syndrome as well as hypertension leading to cardiovascular diseases.

Abstract
Duchenne muscular dystrophy (DMD) is a progressive and fatal muscle-wasting disease caused by DYSTROPHIN deficiency. Cell therapy using muscle stem cells (MuSCs) is a potential cure. Here, we report a differentiation method to generate fetal MuSCs from human induced pluripotent stem cells (iPSCs) by monitoring MYF5 expression. Gene expression profiling indicated that MYF5-positive cells in the late stage of differentiation have fetal MuSC characteristics, while MYF5-positive cells in the early stage of differentiation have early myogenic progenitor characteristics. Moreover, late-stage MYF5-positive cells demonstrated good muscle regeneration potential and produced DYSTROPHIN in vivo after transplantation into DMD model mice, resulting in muscle function recovery. The engrafted cells also generated PAX7-positive MuSC-like cells under the basal lamina of DYSTROPHIN-positive fibers. These findings suggest that MYF5-positive fetal MuSCs induced in the late stage of iPSC differentiation have cell therapy potential for DMD. Wnt agonists at high dose and long term induces dermomyotome cells effectively MYF5+ cell characteristics vary between early- and late-stage differentiation Late-stage MYF5+ cells acquire characteristics resembling fetal muscle stem cells MYF5+ cells recover dystrophin and improves muscular function

Abstract
GPNMB is involved in multiple cellular functions including cell adhesion, stress protection and stem cell maintenance. In skin, melanocyte-GPNMB is suggested to mediate pigmentation through melanosome formation, but details of keratinocyte-GPNMB have yet to be well understood. We confirmed the expression of GPNMB in normal human epidermal keratinocytes (NHEKs) by reducing the expression using siRNA. A higher calcium concentration of over 1.25 mM decreased the GPNMB expression. Histological staining showed that GPNMB was expressed in the basal layer of normal skins but completely absent in vitiligo skins. The normal expression of GPNMB in nevus depigmentosus skin suggested that lack of GPNMB is characteristic of vitiligo lesional skins. IFN-γ and IL-17A, two cytokines with possible causal roles in vitiligo development, inhibited GPNMB expression in vitro. Approximately 4–8% of the total GPNMB expressed on NHEKs were released possibly by ADAM 10 as a soluble form, but the process of release was not affected by the cytokines. The suppressive effect of IFN-γ on GPNMB was partially via IFN-γ/JAK2/STAT1 signaling axis. Decreased GPNMB expression in keratinocytes may affect melanocyte maintenance or survival against oxidative stress although further studies are needed. These findings indicate a new target for vitiligo treatment, focusing on the novel role of IFN-γ and IL-17 in downregulating keratinocyte-GPNMB.

Abstract
Many advantages of endovascular repair for aneurysms have been reported. The compression by aneurysms was not resolved early after endovascular repair. Rectal necrosis caused by residual aneurysms early after endovascular repair is rare. Aneurysm reduction and intestinal resection after embolization was a useful method. Embolization performed earlier assisted surgical decompression of aneurysms.
Introduction Recently, endovascular repair has become the first-line treatment for internal iliac artery aneurysm (IIAA). However, rectal necrosis due to the compression of the residual IIAA early after endovascular repair is rare. Presentation of case We present a rare case of a huge, isolated left IIAA that severely compressed the rectum and ureter. The patient underwent emergency endovascular repair; however, rectal necrosis occurred 10 days later because the repair failed to shrink the size of the aneurismal sac. Discussion We hypothesize that the compression of the residual IIAA caused rectal necrosis. During open surgery, endovascular repair disrupted blood flow within the IIAA, which probably allowed for aneurysm dissection and residual hematoma removal. Conclusion Endovascular repair alone could not immediately release compression on the surrounding organs; however, open surgical removal of aneurysms after successful endovascular repair may be a useful option for IIAAs with compression of surrounding organs.

Abstract
The association between pancreaticoduodenal artery aneurysm (PDAA) and local hemodynamic changes in pancreaticoduodenal arcades is well established. However, there are few case reports of PDAA associated with acute aortic dissection. In this article, we outline and discuss the case of a 61-year-old man diagnosed with a type A acute aortic dissection who underwent emergency surgery and developed sudden-onset severe abdominal pain and shock 10 days later. Contrast-enhanced computed tomography showed a ruptured PDAA with feeding vessels from the gastroduodenal and superior mesenteric arteries, with evidence that the celiac artery was diverged from a false lumen. Transarterial embolization via the superior mesenteric artery alone was not expected to achieve hemostasis, so we performed a hybrid procedure involving transarterial embolization cannulated from superior mesenteric artery with complementary surgical ligation of the gastroduodenal artery. The postoperative course was uneventful, and follow-up contrast-enhanced computed tomography showed no persistence of the aneurysm 8 days after the second operation. This case proposed that visceral arterial malperfusion due to acute aortic dissection can cause PDAA in the early postoperative period. Although previous reports suggest that endovascular treatment is preferable, it may not always be feasible. Since ruptured PDAAs are often not detected during surgery, surgical treatment can be overly invasive. Whereas, transarterial embolization with complementary clamping or ligation of the gastroduodenal artery for ruptured PDAA is less invasive and can control hemorrhage, especially when cannulation to the celiac artery is impossible. Notably, the technique did not cause organ ischemia, presumably because the small collateral vessels of the pancreaticoduodenal arcades permitted sufficient blood flow. If endovascular treatment is unable to achieve rapid hemostasis, this technique may be a useful option for ruptured PDAA.

Abstract
It is very rare case that each esophageal stump become connected and patent spontaneously. Two-stage surgery is useful for esophageal perforation if radical operation is difficult. Esophageal perforation can be resolved without direct closure if appropriate drainage is performed.
Introduction Successful nonoperative management has been reported for esophageal perforation; however, some cases require surgery. Case presentation We presented the case of an 85-year-old woman with iatrogenic thoracic esophageal perforation in whom primary repair or resection of the perforated esophagus was difficult because she was elderly and had severe aortic valve stenosis. Therefore, we selected a two-stage surgery; laparoscopic gastrostomy, jejunostomy, posterior mediastinal drainage, and cervical esophagostomy were performed. We planned reconstruction after the perforation was closed, but endoscopic examination revealed spontaneous patency of each esophageal stump. Endoscopic balloon dilation was necessary because of esophageal stenosis; however, anastomotic surgery was unnecessary. Conclusion This case report suggests that esophageal perforation is resolved without direct closure if appropriate drainage is performed.

Abstract
INTRODUCTION The optimal management strategy for synchronous gastric cancer (GC) and prostate cancer (PCa) remains unclear, particularly in cases in which two cancers are progressive. PRESENTATION OF CASE A 68-year-old man diagnosed with synchronous advanced GC and locally advanced PCa was referred to our institution. Laparoscopic total gastrectomy (LTG) and robotic-assisted radical prostatectomy were simultaneously performed. The postoperative course was similar to the standard postoperative course of LTG alone. Pathological diagnoses were T3N3aM0 gastric adenocarcinoma and T3N0M0 prostatic adenocarcinoma. Adjuvant chemotherapy and adjuvant androgen deprivation therapy (ADT) for GC and PCa were initiated on postoperative days 15 and 27, respectively. Six months subsequent to surgery, the patient received adjuvant chemotherapy and ADT, and no evidence of cancer recurrence was observed. DISCUSSION In terms of survival, curative resection with adjuvant therapy is advantageous for patients with advanced GC or locally advanced PCa. At present, treatment for synchronous cancer should be combined with optimal management for individual cancers. Minimally invasive surgery may play an important role in the multidisciplinary treatment of synchronous advanced cancer. CONCLUSION Combined laparoscopic and robotic surgery for synchronous GC and PCa allows for minimally invasive radical resection and appropriate adjuvant therapy.

Abstract
The case of synchronous primary colorectal cancer and bladder cancer remains rare. Multidisciplinary treatment is required for synchronous advanced colorectal cancer and bladder cancer. Simultaneous laparoscopic resection may be proposed for postoperative multidisciplinary treatment.
Introduction Advances in diagnostic techniques have resulted in an increase in the diagnosis of numerous patients with multiple primary cancers. However, the diagnosis of synchronous primary colorectal cancer and bladder cancer remains rare. Presentation of case A 69-year-old man diagnosed with synchronous advanced cancer of the ascending colon and urinary bladder underwent simultaneous laparoscopic resection. His postoperative course was similar to that of routine colorectal cancer. The patient refused adjuvant therapy. The patient was diagnosed as having recurrence of bladder cancer 3 months after surgery; he died 9 months after surgery. Discussion For multiple primary malignant tumors, simultaneous tumor resection is preferred. Simultaneous laparoscopic resection may be proposed for postoperative multidisciplinary treatment. If an established regimen is determined in the future, neoadjuvant chemotherapy may be an option for the treatment of synchronous advanced cancer. Conclusion Simultaneous laparoscopic surgery is a greatly beneficial approach for synchronous cancer requiring multidisciplinary treatment. Additionally, an appropriate support system for patients is indispensable for completing multidisciplinary treatment.

Abstract
An infrared imaging video bolometer was improved for application to a neutron environment in fusion plasma devices, i.e., the Large Helical Device (LHD). In order to calibrate the thermal characteristics of the activated foil absorber inside the plasma vacuum vessel, the remote-controlled in situ calibration system was improved with high-surface-flatness mirrors. Furthermore, the carbon coating method was improved by introducing a vacuum evaporation technique instead of the conventional spray technique to realize the coating on both sides of the absorber with reproducibility and uniformity. The optimal thickness of the coating was also determined. Owing to these coating improvements, the reproducibility of the effective emissivity on both sides especially was improved. Finally, the variation with the neutron irradiation of the thermal characteristics of the foil absorber was investigated. It was found that the effect was not significant for the total neutron emission of 3.6 × 1018 on LHD.

Abstract
INTRODUCTION Advances in diagnostic techniques and treatment have resulted in an increase in patients with synchronous cancer. Surgical reports of combined laparoscopic and robotic resection for synchronous colorectal and genitourinary cancer are rare. MATERIALS AND METHODS Between August 2015 and November 2017, three patients underwent combined laparoscopic and robotic surgery for synchronous colorectal and genitourinary cancer in our hospital. RESULTS Case 1 was a 59-year-old man with synchronous rectal and prostate cancer treated by combined laparoscopic anterior resection and robotic-assisted prostatectomy. Case 2 was a 77-year-old man with synchronous cancer of transverse colon and left kidney treated by combined laparoscopic transverse colectomy and robotic-assisted partial nephrectomy. Case 3 was a 74-year-old man with synchronous adenocarcinoma of descending colon and prostate treated by combined laparoscopic left hemicolectomy and robotic-assisted prostatectomy. DISCUSSION In simultaneous endoscopic surgery, it is necessary to consider sequence of resection, intraoperative position of patient and port arrangement. Simultaneous surgery allows promptly for postoperative adjuvant chemotherapy. CONCLUSION Combined laparoscopic and robotic surgery for synchronous colorectal and genitourinary cancer is suitable for advanced cancer cases requiring multidisciplinary treatment.

Abstract
INTRODUCTION Laparoscopic surgery has become a standard treatment for inguinal hernia, with it recently being characterized by the use of smaller instruments. However, reports on needlescopic transabdominal preperitoneal repair using one umbilical 5-mm and two lateral 3-mm trocars are extremely rare. METHODS Seven patients with unilateral inguinal hernia underwent this surgical procedure. A 5-mm trocar was inserted from the umbilical and two 3-mm trocars were inserted from the lateral. After dissection of the preperitoneal layer, a mesh was fixed using a tucker inserted from the umbilical 5-mm trocar while viewing through the 3-mm optics from the lateral trocar. RESULTS All procedures were completed without intraoperative complications and conversion to the conventional method. The surgical results of our needlescopic TAPP repair have been shown to not be inferior to those of the conventional method. CONCLUSION Our needlescopic herniorrhaphy using one umbilical 5-mm trocar and two lateral 3-mm trocars is minimally invasive hernia repair.

Abstract
Temporally modulated input mimics physiology. This chemical communication strategy filters the biochemical noise through entrainment and phase-locking. Under laboratory conditions, it also expands the observability space for downstream responses. A combined approach involving microfluidic pulsatile stimulation and mathematical modeling has led to deciphering of hidden/unknown temporal motifs in several mammalian signaling pathways and has provided mechanistic insights, including how these motifs combine to form distinct band-pass filters and govern fate regulation under dynamic microenvironment. This approach can be utilized to understand signaling circuit architectures and to gain mechanistic insights for several other signaling systems. Potential applications include synthetic biology and biotechnology, in developing pharmaceutical interventions, and in developing lab-on-chip models.

Abstract
We studied the changes in the shape of the triangular fibrocatilage (TFC: disc proper) which occur during forearm rotation in disarticulated and articulated wrists. The influence of artificial 3 mm ulnar lengthening on distortion of the disc was also examined. In the disarticulated wrists, slight distortion of the central and radial portions of the TFC was observed in the ulnar neutral variance specimens. More distortion was noted in the radial and central portions of the TFC in specimens with positive ulnar variance or with the ulna lengthened. However, in the articulated wrist, the TFC demonstrated little change in shape during pronosupination even in the ulnar positive variance wrists or with the ulna lengthened. There was no significant change in palmar and dorsal peripheral lengths of the TFC in ulnar neutral, ulnar positive or ulna-lengthened specimens at three rotatory positions of the forearm. These findings suggest that changes in ulnar variance which occur during forearm rotation can produce distortion on the TFC, but the carpus helps to maintain the shape of the TFC during pronation–supination, even with positive ulnar variance.

Abstract
The InfraRed imaging Video Bolometer (IRVB) is a useful diagnostic for the multi-dimensional measurement of plasma radiation profiles. For the application of IRVB measurement to the neutron environment in fusion plasma devices such as the Large Helical Device (LHD), in situ calibration of the thermal characteristics of the foil detector is required. Laser irradiation tests of sample foils show that the reproducibility and uniformity of the carbon coating for the foil were improved using a vacuum evaporation method. Also, the principle of the in situ calibration system was justified.

Abstract
After several years of treatment for type 2 diabetes mellitus, a 69-year-old Japanese man developed an acute painful neuropathy, characterized by bilateral causalgia and dysaesthesia in his cheeks and around his eyes, typically 30 min to 3h after meals. As his glycaemic control deteriorated, his haemoglobin (Hb) A1c level gradually increased from 7-8% to 10.3% and his symptoms became more severe. The pain radiated out along the distribution of the ophthalmic and maxillary divisions of the trigeminal nerve. The patient was treated with insulin therapy and his HbA1c level decreased from 10.3% to 6.8% within 7 months. Five months after initiating insulin therapy, his symptoms showed a dramatic improvement. This was a very unusual case of bilateral acute painful neuropathy that involved the ophthalmic and maxillary divisions of the trigeminal nerve, and in which aggravation of the symptoms clearly related to poor glycaemic control.
