Abstract
The characteristics of the pulmonary cysts on the high-resolution computed tomography (HRCT) chest images are an important diagnostic clue to distinguish among cystic lung diseases. The diagnostic accuracy of HRCT was reported to be as high as 90% by experienced pulmonologists and radiologists. Herein, we report the case of an elderly woman with Birt-Hogg-Dubé syndrome (BHDS) whose HRCT images displayed lymphangioleiomyomatosis-like features of the pulmonary cysts, rendering it difficult for us to diagnose BHDS. This case illustrates the significance of a thorough anamnesis, physical examination, and skin biopsy of facial papules to establish an accurate diganosis.

Abstract
OBJECTIVE There is no established consensus or guidelines for wound management after revascularization for patients with chronic limb-threatening ischemia (CLTI) without severe infection. This study is designed to evaluate the clinical effect of the wound management strategy on toe wounds after revascularization for CLTI. METHODS This retrospective cohort study was performed at eight institutions affiliated with Keio University School of Medicine in Japan and included 261 patients who underwent revascularization for CLTI between April 2019 and July 2021. We identified 132 patients with toe wounds from the database who had restored in-line blood flow to the foot. Patients were divided into two groups by the timing of toe resection after revascularization, which dictated the wound management policy. Group A (62 patients) underwent early toe amputation for suspected osteomyelitis, whereas group B (70 patients) underwent watchful waiting. The primary outcome was wound healing after revascularization; the secondary outcome was major amputation. We compared outcomes between groups A and B after propensity score matching. RESULTS Using propensity score matching, each patient in group A (33 patients) was matched with a patient in group B (33 patients). Wound healing in matched group A was significantly better than that in matched group B (respectively: 1-year wound healing rate: 90.0% vs 68.2%, P < .001; median wound healing time: 65 days vs 258 days, P < .01). Although five major amputations were necessary in matched group B, none were required in matched group A (P = .05). The high rate of major amputations in group B was attributed to the sudden exacerbation of infection. Limb salvage rate in matched group A exceeded matched group B (100.0% vs 90.5%: 1-year limb salvage rate, P = .02). CONCLUSIONS Early toe amputation for highly suspected osteomyelitis in patients with CLTI with toe wounds may expedite wound healing compared with watchful waiting, potentially avoiding unnecessary major amputation. Considering the wound management strategy is crucial when evaluating wound healing outcomes in patients with CLTI with revascularization.

Abstract
Lymphangioleiomyomatosis (LAM) is a tuberous sclerosis complex (TSC)-associated tumor, characterized by the expression of neural crest lineages including neuronal markers. Neural crest cells can differentiate into multiple cell types that contribute to tissues associated with TSC-related tumors, and TSC-related tumors could be specifically associated with distinct neural crest subtypes. This study aimed to clarify the clinicopathological effects of expression of neuronal markers in LAM. Lung tissues from 40 patients with LAM (of whom 13, 1, and 26 had undergone lung transplantation, lobectomy, and partial lung resection, respectively) were immunohistochemically analyzed. All patients were women, and their median age was 36 years (range: 24-62 y). All patients who underwent lung transplantation or lobectomy were classified as LAM histologic score (LHS)-3, whereas those who underwent partial lung resection were classified as LHS-1. LAM cells expressed peripherin (65%), and neuron-specific βIII-tubulin (43%). A comparison of the early (LHS-1) and advanced (LHS-3) stages of LAM revealed that neuron-specific βIII-tubulin was significantly expressed in the early stage of LAM ( P = 0.0009). Neuron-specific βIII-tubulin-positive LAM was associated with younger age ( P < 0.0001), the coexistence of renal angiomyolipoma ( P = 0.027), and the absence of retroperitoneal LAM ( P = 0.045). Furthermore, based on the expression levels of immunohistochemical markers in LAM, 2 distinct clusters with different expression levels of neuronal markers were observed. Approximately 40% to 60% of patients with LAM expressed neuron-specific βIII-tubulin and peripherin. Neuronal expression may be associated with disease severity.

Abstract
BACKGROUND The clinical pulmonary manifestations and genetic features of Birt-Hogg-Dubé syndrome (BHDS) in Asian patients remained unclear. We aimed to clarify the clinical features of BHDS-associated pneumothorax (PTX) and retrospectively investigate potential contributing factors in the largest Asian cohort to date. METHODS We reviewed the clinical and genetic data collected in 2006-2017, from the BHDS patients who were Asian and presented with pulmonary cysts with or without a history of PTX. RESULTS Data from 334 (41.3% males; 58.7% females) patients from 297 unrelated families were reviewed. Among them, 314 (94.0%) patients developed PTX. The median age at the first occurrence of PTX was 32 years, which was significantly lower in males (P = 0.003) and patients without notable skin manifestations (P < 0.001). Seventy-six (24.2%) patients experienced their first PTX episode before the age of 25 years. PTX simultaneously occurred in the bilateral lungs of 37 (11.8%) patients. Among 149 patients who had their first PTX episode at least 10 years before BHDS diagnosis, PTX occurred more frequently in males (P = 0.030) and light smokers than in nonsmokers (P = 0.014). The occurrence of PTX peaked in the early 30s and gradually decreased with age but remained high in females (P = 0.001). We identified 70 unique FLCN germline variants, including duplications (46.4%), substitutions (7.1%), insertions/deletions (30.0%), and variants affecting splicing (12.5%). Approximately 80% of Asian patients suspected of having BHDS could be genetically diagnosed by examining FLCN exons 7, 9, 11, 12, and 13. No apparent genotype-phenotype correlation regarding pulmonary manifestations was identified. CONCLUSIONS Our findings indicate that sex, smoking history, and skin manifestations at BHDS diagnosis significantly influence the clinical features of BHDS-associated PTX. These findings may contribute to the appropriate management and treatment of BHDS-associated PTX.

Abstract
Ultrasound-guided transthoracic needle biopsy is a relatively safe procedure diagnosing subpleural pulmonary mass and has high sensitivity in the diagnosis of lung cancer. However, the usefulness in other rare malignancies is unknown. This case shows the effectiveness in diagnosing not only lung cancer but also rare malignancies including primary pulmonary lymphoma.

Abstract
Abstract
Exosomes are a class of extra cellular vesicles (EVs), with a multi vesicular endosomal origin, that are released by all cell types, with sizes ranging from 30-150nm and a lipid bilayer membrane. They have been shown to play key roles in disease progression and have diagnostic and disease monitoring potential. This study aims to characterize exosomes from the serum of patients with Lymphangioleiomyomatosis (LAM), a rare, low-grade, metastasizing neoplasm that occurs predominantly in females. Using Nanoparticle Tracking Analysis (NTA), serum from LAM patients (n=19) have significantly increased numbers of exosomes compared to serum samples from healthy controls (n=20) (8.9x109 vs 13.8x109 particles/ml; p=0.024). Furthermore, particles counts are significantly negatively correlated with the forced expiratory volume (FEV1) (r=-0.4667; p-value=0.0295) in LAM patients. Metalloproteinase activity in exosomes was measured by zymography. Interestingly, these LAM-derived exosomes had significantly higher activity of Pro-MMP-9 (3-fold increase; p-value=0.0278). We analyzed the effects of serum-derived exosomes on cells from an A549 cell line. Increased expression of vimentin, a major marker of EMT, was observed in cells treated with LAM-derived exosomes compared to healthy controls (1.4-fold increase; p=0.0217). Moreover, we showed by a modified Boyden chamber assay that exosomes derived from serum treatment increases the invasive capacity of A549 cells (fold change of 2.2; p-value=0.0004). We interrogated the LAM Single Cell Atlas and identified increased expression of TWIST1, a key transcription factor for EMT. TWIST1 was increased 8-fold in the lung and was uniquely expressed in 'LAM cells', which had metastasized. Furthermore, proteomic analysis revealed high expression of C3 and C5 in LAM-derived exosomes (respectively 1.4- and 2.1-fold change; p=0.0276 and p=0.0034) suggesting the potential regulatory role of the compliment system in the EMT mediated by exosomes These preliminary results highlight the urge to study the specific mechanistic interplay between MMPs and EMT, mediated by exosomes, and whether exosomes are involved in the metastatic spread of LAM cells to the lung and their role in influencing innate and adaptive immune cell response to this invasion.

Abstract
Coronavirus disease 2019 (COVID-19) has overwhelmed hospitals worldwide. In Japan, serum interferon lambda 3 (IFN-λ3) and C-C motif ligand (CCL) 17 levels have been used as predictive markers for disease progression to severe COVID-19. However, the relationship between these predictive markers and the disease progression of COVID-19 has not been well evaluated. We retrospectively evaluated the patient characteristics, serum IFN-λ3 and CCL17 levels, and comorbidities of 92 patients with mild (n = 20) and moderate (n = 72) COVID-19 who were hospitalized in our institution. The results of the multivariable analysis showed that the positive rates of IFN-λ3, CCL17, and the combination of these markers were significantly elevated in patients with progressed COVID-19. Furthermore, patients who were negative for both markers did not experience disease progression. This study illustrates the importance of measuring these markers to predict disease severity and progression in patients with COVID-19.

Abstract
Electroconvulsive therapy (ECT) has been used for many years as an important treatment modality in patients with schizophrenia. Recently, many new oral medications have become available to treat schizophrenia. However, ECT remains a valuable therapy for patients who are resistant to oral medications. A 16-year-old girl with schizophrenia was admitted to our hospital with hypoxaemia due to negative-pressure pulmonary oedema (NPPE) after her first ECT. NPPE is an exceedingly rare complication after ECT. However, it can result in serious morbidity if not immediately recognized and treated. This case illustrates the importance of recognizing this rare complication.

Abstract
PURPOSE To compare the long-term outcomes of the most widely used third-generation stent grafts, the Endurant and Excluder stent grafts, in Japanese patients using a multicenter registry. MATERIALS AND METHODS A retrospective analysis of endovascular aneurysm repairs for abdominal aortic and iliac artery aneurysms using either the Endurant or the Excluder stent grafts from January 2012 to July 2019 at 10 Japanese hospitals was performed. RESULTS A total of 332 and 378 repairs using the Endurant and Excluder stent grafts, respectively, were analyzed. Although the patients' characteristics were generally similar in the two groups, the Endurant group exhibited significantly shorter (Endurant: 31.5±18.6 mm, Excluder: 37.4±21.0 mm; p<0.001), larger (Endurant: 22.4±4.2 mm, Excluder: 21.7±3.8 mm; p=0.029), and more reversed tapered (Endurant: 12.1%, Excluder: 5.8%; p=0.003) proximal necks. The incidence of instructions for use (IFU) violations was similar between the two groups (Endurant: 59.0%, Excluder: 54.5%; p=0.223). However, the Endurant group had significantly more proximal neck-related IFU violations (54.1% and 46.3%, respectively; p=0.039), more access-related IFU violations (8.1% and 4.0%, respectively; p=0.019), and fewer bilateral hypogastric artery embolizations (5.1% and 9.3%, respectively; p=0.035) compared with the Excluder group. The incidence of intraoperative (Endurant: 3.6%, Excluder: 3.7%; p=0.950) and perioperative complications (Endurant: 3.6%, Excluder: 3.4%, p=0.899) was equivalent in the two groups. However, there was a significantly higher incidence of postoperative type II endoleaks in the Excluder group (Endurant: 28%, Excluder: 46.0%, p<0.001). Aneurysm sac regression was more frequent in the Endurant group (Endurant: 40.7%, Excluder: 31.7%, p=0.013). The Endurant group also had significantly higher rates of sac increase (Endurant: 13.0%, Excluder: 7.7%, p=0.020). Kaplan-Meier curve and log-rank analyses revealed no statistical differences in late complications (p=0.868) and overall survival (p=0.926). CONCLUSIONS There were no statistically significant differences between the Endurant and the Excluder stent grafts in terms of intraoperative, perioperative, and late complication rates; however, the anatomical characteristics of the patients were significantly different.

Abstract
Dendriform pulmonary ossification (DPO) is a rare condition characterized by heterotopic bone production of unknown origin within the pulmonary tissue. Many cases are asymptomatic with slow progression and are often diagnosed incidentally during autopsy. Thus, only few cases are diagnosed while the patient is still alive since surgical lung biopsy is often needed for pathological diagnosis. This is the case of a 37-year-old man treated at our hospital due to abnormal findings on chest x-ray without any symptoms. His high-resolution computed tomography revealed diffuse reticular shadows and micronodules, consistent with calcification. He underwent transbronchial lung cryobiopsy (TBLC) and was diagnosed with idiopathic DPO based on pathological findings. To our knowledge, this is the first reported case of DPO diagnosed using TBLC. TBLC can be a useful yet minimally invasive diagnostic tool to diagnose DPO and other interstitial lung diseases.

Abstract
BACKGROUND Surgical site infection (SSI) is the most common problem after surgery. Although several guidelines have indicated the efficacy of antiseptics, such as chlorhexidine-alcohol and povidone-iodine, in reducing SSI rate, the optimal recommendation is still not established. Olanexidine might have higher bactericidal activity than other antiseptic agents. However, no randomised study has evaluated the efficacy and safety of olanexidine over conventional antiseptics. We compared the effect of aqueous olanexidine and aqueous povidone-iodine on the incidence of SSI following clean-contaminated surgery. METHODS This was a multicentre, prospective, randomised, blinded-endpoint superiority trial for surgical skin antisepsis in clean-contaminated gastrointestinal and hepatobiliary pancreatic surgeries in four Japanese hospitals. Patients aged 20 years or older who underwent elective clean-contaminated wound surgery were randomly assigned in a 1:1 replacement ratio using a computer-generated block randomisation. Patients were randomly assigned to surgical skin antisepsis with an aqueous formulation of 1·5% olanexidine or surgical skin antisepsis with an aqueous formulation of 10% povidone-iodine before surgery. We used olanexidine in a ready-to-use applicator, and povidone-iodine was administered by a brush or by compression using pliers. Both antiseptics were applied from the papilla with a cranial limit and to the upper thigh with a caudal limit. The antiseptics were allowed to dry for 3 min, and then surgery started. Participants, some investigators, and data analysts were masked to treatment allocation. Participant enrolment was done by non-masked investigators. The primary outcome was 30-day SSI assessed in the intention-to-treat population. The surgical wound site of each participant was observed daily. After discharge, participants underwent at least one outpatient visit within 30 days after surgery. This trial is registered with University hospital Medical Information Network, 000031560. FINDINGS Between June 10, 2018, and April 18, 2019, 883 patients were assessed for eligibility. 587 patients were eligible and 294 received olanexidine and 293 received aqueous povidone-iodine before surgery. 30-day SSI occurred in 19 (7%) patients in the olanexidine group and 39 patients (13%) patients in the povidone-iodine group (adjusted risk difference -0·069; 90% CI -0·109 to -0·029; adjusted risk ratio [RR] 0·48, 90% CI 0·30 to 0·74; p=0·002). Five patients (2%) in the olanexidine group and five (2%) in the povidone-iodine group developed adverse skin reactions (adjusted RR 0·99, 95% CI 0·29 to 3·40; p=1·00). INTERPRETATION Olanexidine significantly reduced the occurrence of overall SSI and superficial incisional SSI compared with aqueous povidone-iodine in clean-contaminated surgery. Our results indicate that olanexidine might have a role to prevent SSI in patients who undergo clean-contaminated surgeries. FUNDING Keio University and Ohyama Health Foundation.

Abstract
Background A guide of patient selection for establishing the diagnosis of lymphangioleiomyomatosis (LAM) by transbronchial lung biopsy (TBLB) has not been established, although the pathological confirmation of LAM by lung biopsy is desirable, particularly when patients have no additional test results except typical findings of computed tomography (CT) of the chest. Methods We retrospectively reviewed the medical records of LAM patients who visited at our hospital from January 2010 to September 2018. We found 19 patients who underwent TBLB and collected the following data to investigate which parameters could predict the TBLB diagnostic positivity for LAM: age, degree of exertional dyspnea, pulmonary function test, cystic lung destruction visually assessed by the modified Goddard scoring system (MGS), serum level of vascular endothelial growth factor-D, and TBLB-related data. Results The diagnosis of LAM was established by TBLB in 15 of 19 patients (78.9%) and no serious complications occurred. MGS was significantly higher in the TBLB-positive group than the TBLB-negative group. In LAM patients without pulmonary lymphatic congestion on CT (N = 16), multivariable logistic regression analysis revealed that MGS and FEV1/FVC were independent contributing parameters for TBLB diagnostic positivity. However, the analysis of Bayesian inference demonstrated that MGS is a better predictor than FEV1/FVC; the probability of establishing diagnosis exceeds 80% if MGS is > 2 (i.e., area of cystic destruction occupies > 25% of lung parenchyma on CT). Conclusions MGS may be a helpful and convenient tool to select candidates for TBLB to establish the diagnosis of LAM pathologically.

Abstract
OBJECTIVE/BACKGROUND It was hypothesised that a helical stent with expanded polytetrafluoroethylene (ePTFE) grafts could provide a preventive effect for external iliac artery (EIA) limb occlusion following endovascular aortic aneurysm repair (EVAR). Therefore, a post-hoc analysis of a Japanese multicentre database was conducted to assess the impact of the stent graft design on EIA limb occlusion rates. METHODS Patients who underwent EVAR with EIA limb deployment between 2008 and 2016 were evaluated. The stent graft limbs were divided into two groups: group A comprised stent graft limbs made of a helical stent with ePTFE grafts (Excluder; n = 255), and group B comprised stent graft limbs made of a Z stent with polyester grafts (Zenith, Flex and Endurant; n = 173). The main outcome was the incidence of limb occlusion and severe limb stenosis (EIA related limb complications). The risk factors for EIA related limb complications were analysed and the midterm results between groups A and B compared. Fine-Gray generalisation of the proportional hazards model was used after propensity score matching to calculate the hazard ratio (HR). RESULTS One complication occurred in group A and 10 complications occurred in group B. The risk factors for EIA related limb complications for the entire group were a stent graft limb size ≤10 mm (HR 5.41; p = .01) and inclusion in group B (HR 14.9; p = .009). After propensity matching, group A (n = 159) was matched with group B (n = 159). The cumulative incidence function of EIA related limb complications at five years was 0.66% in group A and 7.8% in group B (HR 8.67; p = .039). CONCLUSION Stent graft design can affect limb patency in EIA limb deployment. When EIA limb deployment is necessary for patients with a small EIA, such as Japanese patients, stent graft limbs made of a helical stent with ePTFE should be used to reduce the risk of limb occlusion.

Abstract
INTRODUCTION The prevalence of surgical site infection (SSI) remains higher in gastrointestinal surgery than in other surgeries. Although several guidelines have indicated the efficacy of chlorhexidine and povidone-iodine in reducing the SSI rate, the optimal recommendation has still not been established. Therefore, it is necessary to determine the more effective antiseptic for surgical site preparation. Olanexidine (1.5% olanedine, Otsuka Pharmaceutical Factory, Tokushima, Japan), which is a new antiseptic in Japan, has antimicrobial activity against a wide range of bacteria, including Gram-positive and Gram-negative bacteria. Our study will contribute to determining a new antiseptic for use in gastrointestinal and other surgeries. METHODS AND ANALYSIS We propose a multicentre, randomised controlled clinical trial for comparing two treatments, that is, 1.5% olanexidine or 10% povidone-iodine, for surgical skin preparation to prevent SSI in clean-contaminated gastrointestinal surgeries with surgical wounds. Patients aged ≥20 years at the time of consent will be included. The primary outcome measure is the 30-day postoperative SSI rate. For the primary analysis, which is aimed at comparing the treatment effects, the adjusted risk ratio and its 95% CI will be estimated using the Mantel-Haenszel method. ETHICS AND DISSEMINATION The protocol was first approved by the Institutional Review Board of Keio University School of Medicine, followed by the institutional review board of each participating site. Participant recruitment began in June 2018. The final results will be published in international peer-reviewed medical journals. TRIAL REGISTRATION NUMBER UMIN 000031560; Pre-results.

Abstract
Background Since the concept of intraductal tubulopapillary neoplasm (ITPN) was introduced in the current World Health Organization classification of tumors, the number of reports of ITPN occurrence has increased gradually. However, ITPN is usually located in the main pancreatic duct, with few reports of a branch duct ITPN. As a result, imaging protocols for the diagnosis of a branch duct ITPN have not been established. Case presentation We report a case of a concurrent presentation of a branch duct ITPN and intraductal papillary mucinous neoplasm (IPMN) in the head of the pancreas, with a superior mesenteric artery (SMA) aneurysm. Initially, the cystic masses in the pancreatic head were diagnosed as branch duct IPMNs, with treatment consisting of a pylorus-preserving pancreaticoduodenectomy, in combination with an aneurysmectomy performed for treatment of the SMA aneurysm. Pathological examination confirmed these cysts were a combination of branch-type ITPN and IPMN. The patient recovered from the treatment without complication, with no evidence of recurrence over a period of 34 months post-surgery. Conclusion This case report of a synchronous presentation of an ITPN and IPMN indicates the difficulty in differentiating these two types of neoplasms in the branch duct of the pancreatic head.

Abstract
Our understanding of physics at very early Universe, as early as 10−35 s after the Big Bang, relies on the scenario known as the inflationary cosmology. Inflation predicts a particular polarization pattern in the cosmic microwave background, known as the B-mode yet the strength of such polarization pattern is extremely weak. To search for the B-mode of the polarization in the cosmic microwave background, we are constructing an off-axis rotating telescope to mitigate systematic effects as well as to maximize the sky coverage of the observation. We will discuss the present status of the GroundBIRD telescope.

Abstract
BACKGROUND Interstitial lung diseases induced by anticancer agents (ILD-AA) are rare adverse effects of anticancer therapy. However, prognostic biomarkers for ILD-AA have not been identified in patients with advanced lung cancer. Our aim was to analyze the association between serum biomarkers sialylated carbohydrate antigen Krebs von den Lungen-6 (KL-6) and surfactant protein D (SP-D), and clinical characteristics in patients diagnosed with ILD-AA. METHODS Between April 2011 and March 2016, 1224 advanced lung cancer patients received cytotoxic agents and epidermal growth factor receptor tyrosine kinase inhibitors at Juntendo University Hospital and Juntendo University Urayasu Hospital. Of these patients, those diagnosed with ILD-AA were enrolled in this case control study. ΔKL-6 and ΔSP-D were defined as the difference between the levels at the onset of ILD-AA and their respective levels prior to development of ILD-AA. We evaluated KL-6 and SP-D at the onset of ILD-AA, ΔKL-6 and ΔSP-D, the risk factors for death related to ILD-AA, the chest high resolution computed tomography (HRCT) findings, and survival time in patients diagnosed with ILD-AA. RESULTS Thirty-six patients diagnosed with ILD-AA were enrolled in this study. Among them, 14 patients died of ILD-AA. ΔSP-D in the patients who died was significantly higher than that in the patients who survived. However, ΔKL-6 did not differ significantly between the two groups. Moreover, ΔSP-D in patients who exhibited diffuse alveolar damage was significantly higher than that in the other patterns on HRCT. Receiver operating characteristic curve analysis was used to set the optimal cut off value for ΔSP-D at 398 ng/mL. Survival time for patients with high ΔSP-D (≥ 398 ng/mL) was significantly shorter than that for patients with low ΔSP-D. Multivariate analysis revealed that ΔSP-D was a significant prognostic factor of ILD-AA. CONCLUSIONS This is the first research to evaluate high ΔSP-D (≥ 398 ng/mL) in patients with ILD-AA and to determine the risk factors for ILD-AA in advanced lung cancer patients. ΔSP-D might be a serum prognostic biomarker of ILD-AA. Clinicians should evaluate serum SP-D during chemotherapy and should carefully monitor the clinical course in patients with high ΔSP-D.

Abstract
Bioresorbable scaffolds have the potential to overcome several problems associated with metallic stents. Bioresorbable poly-L-lactic acid (PLLA) scaffold implantation for the treatment of peripheral artery disease has already been reported in animal models and clinical trials; however, no studies comparing PLLA scaffolds and bare metal stents (BMSs) with regard to early vascular morphological changes, identified using intravascular ultrasound (IVUS) analysis, have been reported. In this study, PLLA scaffolds and BMSs were implanted bilaterally in iliac arteries of five miniature pigs. Digital subtraction angiography and IVUS were performed before and immediately after stent implantation and at 6-week follow-up. All PLLA scaffolds and BMSs were patent at 6-week follow-up. Per IVUS analysis, the percent area stenosis did not significantly differ between PLLA scaffolds and BMSs (65.7% vs. 67.2%, P = .761). Furthermore, percent vessel lumen change also did not differ significantly. Neointima formation (the neointimal area plus medial area) was significantly less with PLLA scaffolds than with BMSs (15.65 mm2 vs. 25.69 mm2, P < .001). In conclusion, based on IVUS results, short-term results after stent implantation in porcine iliac arteries were comparable between PLLA scaffolds and BMSs. Therefore, PLLA scaffolds are safe and feasible for implantation in peripheral arteries.

Abstract
A 62-year-old man with asthma presented with a 1-month history of wheezing and exertional dyspnea. Although the wheezing symptoms disappeared after systemic corticosteroid therapy, the exertional dyspnea and hypoxemia did not improve. A diagnosis of intravascular large B-cell lymphoma (IVLBCL) with pulmonary involvement was suspected because of the increased serum lactic dehydrogenase (LDH) and soluble interleukin-2 receptor (sIL-2R) level, increased alveolar-arterial oxygen difference (AaDO2), decreased pulmonary diffusing capacity for carbon monoxide (DLCO) and scintigraphic, computed tomography (CT) and 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET)-CT findings. The patient was diagnosed as having IVLBCL with pulmonary involvement based on a pathological analysis of a random skin biopsy and a transbronchial lung biopsy. IVLBCL should be considered in patients with symptoms of asthma that are refractory to corticosteroid treatment.

Abstract
Background Loxoprofen is a nonsteroidal anti-inflammatory drug used in the treatment of many diseases. However, there are no case reports about loxoprofen-induced pneumonia. We have encountered a rare case of loxoprofen-induced pneumonia. Case presentation We report the case of a 71-year-old Japanese woman who was initially treated with loxoprofen for fever. She was admitted to our hospital because of worsening of her symptoms, including fever and dyspnea. Her symptoms improved after treatment with ceftriaxone. Seven days after admission, she again developed high fever. She was again treated with loxoprofen and levofloxacin. However, acute respiratory failure developed after initiation of loxoprofen treatment. Chest computed tomography showed peribronchovascular consolidation. She was diagnosed with loxoprofen-induced pneumonia for which she was administered steroids. After treatment, her dyspnea and radiological findings improved. Conclusions The findings in this case report reveal an association between treatment with a nonsteroidal anti-inflammatory drug and pneumonia. This rare case was diagnosed after accidental retreatment with loxoprofen. This is the first report of loxoprofen-induced pneumonia.

Abstract
Bevacizumab is a monoclonal antibody targeting the vascular endothelial growth factor receptor and a key drug for advanced non-small cell lung cancer. There are few reports describing bevacizumab-induced chronic interstitial pneumonia. A 62-year-old man with advanced non-small cell lung cancer was admitted to our hospital with dyspnea. He previously received four courses of carboplatin plus paclitaxel with bevacizumab combination therapy and thereafter received four courses of maintenance bevacizumab monotherapy. A chest-computed tomography scan on admission revealed diffuse ground glass opacity. He had not received any other drugs and did not have pneumonia. Thus, he was diagnosed with bevacizumab-induced chronic interstitial pneumonia and was treated with a high dose of corticosteroids. After steroid treatment, his dyspnea and radiological findings improved. This case report is the first description of bevacizumab-induced chronic interstitial pneumonia during maintenance therapy in a patient with non-small cell lung cancer.

Abstract
Only few studies have addressed the surgical revascularization in patients with both connective tissue disease (CTD) and critical limb ischemia (CLI), and the evidence for the endovascular treatment (EVT) is lacking in such patients. The main purpose of this study is to assess our outcome of EVT in patients with CTD and ischemic leg ulcers and review the current situation of the revascularization in such patients. Medical records of 10 consecutive patients with coexistent CTD and CLI-related leg ulcers (in 11 limbs) treated endovascularly at our institution between 2009 and 2013 were reviewed retrospectively. The patients had rheumatoid arthritis (n = 5), systemic lupus erythematosus (n = 1), progressive systemic scleroderma (n = 3), or polyarteritis nodosa (n = 1). EVT was technically successful in all the cases. No procedure-related morbidity or mortality occurred. During the mean follow-up period of 26 months, there were no major amputations, and sustained clinical improvement (ulcer healing and reduction in Rutherford category) was observed in eight limbs. The overall 1-year rates of amputation-free survival and freedom from reintervention were 89 and 81%, respectively. In our series of patients with CTD and ischemic leg ulcers, EVT had acceptable outcomes and may be recommended as a safe and reasonably effective initial treatment option for such patients.

Abstract
A 66-year-old man was admitted due to repeated syncope, and the electrocardiogram showed complete atrioventricular block (CAVB). He had moderate aortic valve stenosis (AS) with a severely calcified valve. This case indicates that if calcification spreads into the cardiac conduction system, it may cause CAVB. Although CAVB is not typically considered a main cause of syncope in AS patients, it should nevertheless be considered in the differential diagnosis.

Abstract
Cetuximab is an agent approved as epidermal growth factor receptor (EGFR)-positive for unresectable advanced or recurrent colorectal cancer. A 58-year-old man with liver metastasis had relapsed after resection of rectal cancer. We treated him with cetuximab monotherapy as third-line chemotherapy after treatment failures with infusional 5-FU, LV and oxaliplatin (FOLFOX4 regi- men); and infusional 5-FU, LV and irinotecan(FOLFIRI regimen). The patient was administered cetuximab (400 mg/m² initial dose and 250 mg/m²/ week thereafter). After sixteen weeks of treatment, a computed tomography scan revealed reduced sizes of the liver metastases. The tumor response has still been maintained after thirty courses of treatment, and the chemotherapeutic response was evaluated as a partial response according to the Response Evaluation Criteria In Solid Tumor guidelines. The main toxicity was a grade 2 rash, but was manageable by topical steroid and moisturizing agent. We have added some review of the literature, and the cetuximab therapy is reported.

Abstract
Large-scale mapping observations of the 3P1-3P0 fine-structure transition of atomic carbon (C i, 492 GHz) and the J=3-2 transition of CO (346 GHz) toward the Orion A molecular cloud have been carried out with the Mount Fuji submillimeter-wave telescope. The observations cover 9 deg2 and include the Orion Nebula M42 and the L1641 dark cloud complex. The C i emission extends over almost the entire region of the Orion A cloud and is surprisingly similar to that of 13CO (J=1-0). The CO (J=3-2) emission shows a more featureless and extended distribution than C i. The C i/CO (J=3-2) integrated intensity ratio shows a spatial gradient running from the north (0.10) to the south (1.2) of the Orion A cloud, which we interpret as a consequence of the temperature gradient. On the other hand, the C i/13CO (J=1-0) intensity ratio shows no systematic gradient. We have found a good correlation between the C i and 13CO (J=1-0) intensities over the Orion A cloud. This result is discussed on the basis of photodissociation region models.

Abstract
The rotational spectral lines of the 13C isotopic species of CCS (13CCS, C13CS, and 13C13CS) have been observed using a Fourier transform microwave spectrometer in combination with a pulsed-discharge nozzle. The hyperfine-resolved JN = 10-01, JN = 21-10, and JN = 32-21 transitions have been observed in the 11-, 22-, and 33-GHz regions, respectively, with an accuracy of about 5 kHz. The observed transition frequencies for 13CCS and C13CS are analyzed simultaneously with millimeter-wave data, and the hyperfine interaction constants for both species are determined accurately. Astronomical implications for these radicals are discussed. Copyright 1997 Academic Press. Copyright 1997Academic Press

Abstract
BACKGROUND F1-ATPase, an oligomeric assembly with subunit stoichiometry alpha 3 beta 3 gamma delta epsilon, is the catalytic component of the ATP synthase complex, which plays a central role in energy transduction in bacteria, chloroplasts and mitochondria. The crystal structure of bovine mitochondrial F1-ATPase displays a marked asymmetry in the conformation and nucleotide content of the catalytic beta subunits. The alpha 3 beta 3 subcomplex of F1-ATPase has been assembled from subunits of the moderately thermophilic Bacillus PS3 made in Escherichia coli, and the subcomplex is active but does not show the catalytic cooperativity of intact F1-ATPase. The structure of this subcomplex should provide new information on the conformational variability of F1-ATPase and may provide insights into the unusual catalytic mechanism employed by this enzyme. RESULTS The crystal structure of the nucleotide-free bacterial alpha 3 beta 3 subcomplex of F1-ATPase, determined at 3.2 A resolution, shows that the oligomer has exact threefold symmetry. The bacterial beta subunits adopt a conformation essentially identical to that of the nucleotide-free beta subunit in mitochondrial F1-ATPase; the alpha subunits have similar conformations in both structures. CONCLUSIONS The structures of the bacterial F1-ATPase alpha and beta subunits are very similar to their counterparts in the mitochondrial enzyme, suggesting a common catalytic mechanism. The study presented here allows an analysis of the different conformations adopted by the alpha and beta subunits and may ultimately further our understanding of this mechanism.
