Abstract
Study question
Is it possible to identify the optimal puncture position by image analysis where oocyte degeneration is reduced in ICSI procedure?
Summary answer
Visualizing the likelihood of unintentional membrane rupture (UMR) using image analysis can reduce oocyte degeneration and thereby generate more embryos available for treatment.
What is known already
It is known that the oocyte degeneration after both conventional-ICSI and Piezo-ICSI are often observed when UMR occurs during the puncturing process and the likelihood of UMR may depends on the location of the puncture site on the oolemma. Identifying the appropriate puncturing position may decrease the likelihood of membrane rupture and thus degeneration, however, there are no studies identifying the optimal puncture position during ICSI.
Study design, size, duration
We have developed the ICSI Position Detector (IPD), which can identify an area where rupture is likely to occur and visualize it on a video monitor. This study included 1,110 mature oocytes retrieved from 190 consenting patients. Matured oocytes were inseminated either by Conventional-ICSI (n = 437, average maternal age: 39.1±4.6 y.o.) or Piezo-ICSI (n = 673, average maternal age: 38.6±4.5 y.o.). ICSI was performed blindly, moving images were recorded and analyzed retrospectively during ICSI using IPD.
Participants/materials, setting, methods
Inseminated oocytes were subsequently divided into two groups according to IPD results, oocytes on which ICSI was performed at the position with a low chance of UMR (appropriate group), and with a high chance of UMR (non-appropriate group) by IPD. The rates of UMR, degeneration, fertilization (2PN), blastocyst formation, and good-quality blastocyst (Grade 3BB and above on day 5 by the Gardner scoring) were compared between the two groups of both conventional-ICSI and Piezo-ICSI.
Main results and the role of chance
The areas in which UMR is less likely to occur and more likely to occur are heterogeneously distributed. When ICSI was performed blindly, about half was from the non-appropriate position. In appropriate group of Piezo-ICSI, rates of UMR (4.3% vs. 17.4%, P < 0.001) and degeneration (1.0% vs. 5.7%, P < 0.001) were significantly lower than those of non-appropriate group, whereas rates of fertilization (88.0% vs. 78.4%, P < 0.01) and blastocyst formation (57.8% vs. 45.9%, P < 0.01) were significantly higher than those of non-appropriate group, respectively. The rate of good-quality blastocyst (28.8% vs. 24.9%) was in favor of appropriate group, but not significantly different. In appropriate group of Conventional-ICSI, rates of UMR (6.7% vs. 20.6%, P < 0.001) and degeneration (1.5% vs. 6.6%, P < 0.01) were significantly lower than those of non-appropriate group, whereas rate of fertilization (88.7% vs. 69.5, P < 0.001) was significantly higher than those of non-appropriate group, respectively. The rates of blastocyst formation (37.5% vs. 35.3%), good-quality blastocyst (21.3% vs. 18.7%) were all in favor of appropriate group, but not significantly different.
Limitations, reasons for caution
This is a single private fertility clinic study. Its reproducibility should be assessed in different laboratory conditions and the hands of different operators. Moreover, specific studies should be addressed on the effect of the other putative confounders under investigation (e.g. kind of ovulation trigger, patient demographics, culture environment, etc.).
Wider implications of the findings
This study demonstrated that the IPD is useful to identify the optimal puncture location site to prevent UMR on ICSI procedure, resulting in reducing UMR and degeneration of the oocytes and increasing culture results, thereby, generating more embryos available for transfer or cryopreservation.

Abstract
The world’s population is aging, and intergenerational conflicts between older adults and young people are becoming more serious. This study focused on ageism as a cause of intergenerational conflicts and older adults’ diminished mental health status. We conducted an online survey of older Japanese participants (n = 1.096). Our results indicated that older adults who perceived more ageism directed toward them (1) had more negative attitudes toward young people and (2) had lower life satisfaction, which persisted even after controlling for variables such as old age identity and depressive tendencies. Accordingly, we suggest that ageism may reinforce intergenerational conflicts between older adults and young people and compromise older adults’ mental health status. The findings of this study can aid gerontological and psychological research aimed at reducing ageism.

Abstract
Abstract
Background
Critical limb ischemia (CLI) is the most progressed manifestation of peripheral artery disease. Although patients with CLI commonly complicate with severely calcified lesions in infrapopliteal lesions, the prognostic impact of infrapopliteal arterial calcification on wound healing in patients with CLI has not been systematically studied.
Purpose
The aim of current study was to elucidate the prognostic impact of infrapopliteal arterial calcification on wound healing in CLI undergoing endovascular therapy (EVT).
Methods
This study enrolled 639 CLI patients with tissue loss (age 74±10 years, male 62%, diabetes 69%, hemodialysis 57%, Rutherford class 5 77%, class 6 23%) primarily treated with EVT for the infrapopliteal lesions between April 2010 and December 2015. Arterial calcification was assessed by high intensity fluoroscopy and classified into 3 groups as follows; 1) none, 2) unilateral and 3) bilateral calcification. The primary outcome measure was complete wound healing. The predictors of the outcome were evaluated by Cox proportional hazards regression analysis.
Results
During a mean follow-up period of 22±19 months, 1-year wound healing rate were 59.0%. In Kaplan-Meier analysis, 1-year wound healing rate was worse in patients with bilateral calcification than in those with unilateral or none calcification (Figure, 46.2% versus 55.1% versus 67.8%, P<0.001). After multivariate analysis, the predictors of wound healing were non-ambulatory status (hazard ratio (HR) 0.67 [95% confidential interval (CI) 0.53–0.85], P=0.001) and bilateral calcification (HR 0.75 [95% CI 0.47–0.98], versus none or unilateral calcification, P=0.036).

Conclusion
Infrapopliteal Arterial calcification as well as non-ambulatory status was associated with wound healing in patients with CLI.

Abstract
Abstract
Background
Recent randomized, placebo-controlled trial in patients with type 2 diabetes demonstrated that the sodium-glucose cotransporter 2 inhibitors reduced mortality, cardiovascular events and hospitalization for heart failure. However, those trials were not specialized design to investigate the effect of sodium-glucose cotransporter 2 inhibitors in patients with heart failure, in particular with heart failure with preserved ejection fraction.
Purpose
The aim of this study was to evaluate the drug efficacy of luseogliflozin, a sodium-glucose cotransporter 2 inhibitor, compared with voglibose, an alpha-glucosidase inhibitor, using brain natriuretic peptide (BNP) in type 2 diabetes patients with heart failure with preserved ejection fraction.
Methods
This study was a prospective, multicenter, open-label, randomized-controlled trial, comparing luseogliflozin 2.5 mg once daily or voglibose 0.2 mg three times daily in patients with type 2 diabetes suffering from heart failure with preserved ejection fraction (left ventricular ejection fraction >45% and BNP ≥35 pg/ml2) in a 1:1 randomization fashion. Randomization was undertaken using a computer-generated random sequence web response system. The primary outcome was the difference from baseline in BNP after 12 weeks of treatment between two drugs. The key secondary outcomes were the change from baseline in left ventricular ejection fraction and E/e' in echocardiographic parameters, body weight, glycohemoglobin level after 12 weeks of treatment. The safety outcomes included the incidence of major adverse cardiovascular events, hypoglycemic adverse events, and urinary tract infection.
Results
Between December 2015 and September 2018, 173 patients from 16 hospitals and clinics have been included in this study. Of those, 83 patients were assigned to receive luseogliflozin and 82 to receive voglibose. There was no significant difference in the reduction in the BNP concentration after 12 weeks from baseline between the two groups; the ratio of the average values at week 12 to the baseline value was 0.91 in the luseoglifllzin group as compared with 0.98 in the voglibose group (percent change, −9.0% vs. −1.9%, ratio of change with luseogliflozin vs. voglibose, 0.93; 95% confidence interval, 0.78 to 1.10; p=0.26). The key secondary outcomes including left ventricular ejection fraction, E/e', body weight, glycohemoglobin level and the safety outcomes did not differ significantly between the two groups.
Conclusions
In type 2 diabetes patients with heart failure with preserved ejection fraction, the administration of luseogliflozin did not lead to a significant reduction in the BNP concentration than that of voglibose. Left ventricular ejection fraction, E/e', body weight and glycohemoglobin level after 12 weeks of treatment, comparing with at baseline did not differ significantly between the two groups.

Abstract
Abstract
Background
Biodegradable polymer drug-eluting stent (BP-DES) has been developed to improve clinical outcomes after percutaneous coronary intervention (PCI) for patients presenting coronary artery disease (CAD). Although BP-DES showed non-inferior safety and efficacy to durable polymer DES (DP-DES) in several randomized clinical trials, hemodialysis (HD) patients, who have been well known as high risk population for adverse events, were excluded in the most of trials. Therefore, there are limited data comparing the clinical outcomes between BP-DES and DP-DES in HD patients with CAD after PCI.
Purpose
The purpose of this study was to investigate clinical outcomes in HD patients after BP-DES implantation compared with those after DP-DES implantation.
Methods
We retrospectively analyzed 234 HD patients (male 74%, mean age 71±10 years) undergoing PCI for 404 lesions with 472 DESs (71 patients for 138 lesions with 170 BP-DESs [91 Ultimaster and 79 Synergy] and 163 HD patients for 266 lesions with 302 DP-DESs [219 Xience, 53 Promus and 30 Resolute]) from 2011 to 2017. Two-year clinical outcomes were compared between BP-DES group and DP-DES group. The primary outcome measure was the incidence of target lesion revascularization (TLR), while the secondary outcome measures were the occurrence of cardiac death (CD), stent thrombosis (ST), myocardial infraction (MI), target vessel revascularization (TVR), non-TVR and major adverse cardiac event (MACE) defined as a composite of CD, MI, and TVR. Outcome measures were estimated by the Kaplan-Meier method and the differences between BP-DES group and DP-DES group were assessed by the log-rank test. We also conducted Cox's proportional hazard model to identify predictors for TLR occurrence.
Results
Baseline patient and lesion characteristics were similar between the two groups. The two-year incidence of TLR was not significantly different between BP-DES group and DP-DES group (14.1% vs. 22.2%, p=0.391). The two-year incidences of CD (17.3% vs. 17.5%, p=0.381), ST (0% vs. 3.9%, p=0.133), MI (4.2% vs. 5.8%, p=0.965), TVR (21.3% vs. 27.5%, p=0.586), non-TVR (26.1% vs. 31.3%, p=0.439) and MACE (41.1% vs. 42.6%, p=0.526) were also not different between the two groups. After multivariate analysis, diabetes mellitus (hazard ratio 1.97; 95% confidence interval 1.03–3.78, p=0.004) was independently associated with TLR occurrence in HD patients.
Two-year clinical outcomes of HD patient
Conclusions
At two-year follow-up after PCI, BP-DES had comparable safety and efficacy profiles to DP-DES in HD patients presenting CAD.

Abstract
Bronchodilators are essential for the perioperative management of patients with chronic obstructive pulmonary disease (COPD) undergoing surgery for lung cancer. The objective of the present study was to examine whether the usage of a long-acting β2-agonist (LABA) with a long-acting muscarinic antagonist (LAMA) could optimize preoperative lung function and reduce the risk for postoperative pulmonary complications. Thirty-two consecutive patients with moderate-to-severe COPD who underwent a lobectomy for lung cancer and received preoperative LAMA (n=19) or LAMA/LABA (n=13) therapy between January 2005 and December 2015 were enrolled in this retrospective study. The improvement of preoperative pulmonary function and the postoperative morbidity were compared between the patients with preoperative LAMA, and LAMA/LABA therapy. Increases in the forced expiratory volume in one second (FEV1) were significantly larger in the LAMA/LABA group than in the LAMA group (0.26±0.05 l vs. 0.07±0.05 l; P=0.0145). More patients in the LAMA/LABA group than in the LAMA group showed a marked improvement of >10% in %FEV1 after bronchodilators (85 vs. 32%; P=0.0046). The incidence of postoperative pneumonia was significantly lower in the LAMA/LABA group than in the LAMA group (0 vs. 26%; P=0.044). In conclusion, the present study showed that preoperative LAMA/LABA therapy was associated with larger improvements in preoperative pulmonary function and less postoperative pneumonia than LAMA therapy. These results may lead to greater improvements in FEV1 and less postoperative pneumonia by encouraging preoperative LAMA/LABA therapy in this patient population.

Abstract
PURPOSE To investigate the aqueous and vitreous penetration of levofloxacin, the drug was administered topically and/or orally to patients undergoing vitrectomy. METHODS Thirty-six patients undergoing initial vitrectomy with phacoemulsification and aspiration (PEA) were enrolled, and were divided randomly into three groups. Group 1 was treated with topical application of levofloxacin (three times on the day before surgery and seven times on the day of surgery), Group 2 received oral administration of levofloxacin (200 mg twice on the day before surgery and 200 mg at 3 hours before surgery), and Group 3 received both topical and oral levofloxacin according to the above schedules. The concentration of levofloxacin was measured in aqueous humor and vitreous fluid samples obtained during surgery. RESULTS In Groups 1, 2, and 3, the mean levofloxacin concentration in aqueous humor was 0.765+/-0.624 micro g/mL, 1.279+/-0.440 micro g/mL, and 1.823+/-0.490 micro g/mL, respectively, while the mean levofloxacin concentration in vitreous fluid was <0.02 micro g/mL, 1.455+/-0.445 micro g/mL, and 1.369+/-0.530 micro g/mL, respectively. CONCLUSIONS Oral administration of levofloxacin at a dose of 400 mg/day was sufficient for the prophylaxis of ocular infections, because the drug concentrations in both aqueous humor and vitreous fluid were higher than the MIC90 values for major ocular pathogens. Topical application of levofloxacin achieved adequate drug levels in aqueous humor, but not in vitreous fluid, while combined topical and oral administration had an additive effect on the drug concentration in aqueous humor.

Abstract
PURPOSE To evaluate the results and complications of combined pars plana vitrectomy (PPV), phacoemulsification and aspiration (PEA), and intraocular lens (IOL) implantation. METHODS A total of 117 eyes from 114 patients who had undergone PPV combined with PEA and IOL implantation were retrospectively analyzed. Combined surgery was performed for a wide variety of vitreoretinal diseases. Intraoperative and postoperative complications were also reviewed. RESULTS The postoperative BCVA improved by 2 lines or more in 85 eyes (72.6%). Intraoperative complications consisted of retinal tears in 14 eyes (12.0%) and posterior capsular rupture in 2 eyes (1.7%). Iatrogenic retinal tears occurred more frequently in eyes with a macular hole than in eyes with any other disease (p=0.005, chi-square test). Postoperative complications consisted of posterior capsule opacification (PCO) (21 eyes), transient IOP elevation (29 eyes), vitreous hemorrhage (6 eyes), anterior chamber fibrin exudation (11 eyes), posterior iris synechia (8 eyes), neovascular glaucoma (1 eye), and recurrent retinal detachment (RD) (2 eyes). Fibrin exudation occurred more frequently in eyes with proliferative diabetic retinopathy (PDR) and RD than in eyes with any other disease (p=0.03, chi-square test). PCO occurred more frequently in eyes with PDR than in eyes with any other disease (p=0.03, chi-square test). CONCLUSIONS The present study suggests that a high success rate can be achieved when recently improved PPV techniques are combined wi th PEA and IOL implantation. The complications that were observed following this combined treatment varied with respect to the vitreoretinal disease present prior to surgery.

Abstract
BACKGROUND We conducted a multicenter randomized study of adjuvant S-1 administration schedules for surgically treated pathological stage IB-IIIA non-small cell lung cancer patients. METHODS Patients receiving curative surgical resection were centrally randomized to arm A (4 weeks of oral S-1 and a 2-week rest over 12 months) or arm B (2 weeks of S-1 and a 1-week rest over 12 months). The primary endpoints were completion of the scheduled adjuvant chemotherapy over 12 months, and the secondary endpoints were relative total administration dose, toxicity, and 3-year disease-free survival. RESULTS From April 2005 to January 2012, 80 patients were enrolled, of whom 78 patients were eligible and assessable. The planned S-1 administration over 12 months was accomplished to 28 patients in 38 arm A patients (73.7%) and to 18 patients in 40 arm B patients (45.0%, p = 0.01). The average relative dose intensity was 77.2% for arm A and 58.4% for arm B (p = 0.01). Drug-related grade 3 adverse events were recorded for 11% of arm A and 5% of arm B (p = 0.43). Grade 1-3 elevation of bilirubin, alkaline phosphatase, aspartate aminotransferase, and alanine transaminase were more frequently recorded in arm A than in arm B. The 3-year disease-free survival rate was 79.0% for arm A and 79.3% for arm B (p = 0.94). CONCLUSIONS The superiority of feasibility of the shorter schedule was not recognized in the present study. The conventional schedule showed higher completion rates over 12 months (p = 0.01) and relative dose intensity of S-1 (p = 0.01). Toxicity showed no significant difference among the shorter schedule and the conventional schedule, except for grade 1-3 elevation of bilirubin. TRIAL REGISTRATION This randomized multicenter study was retrospectively registered with the UMIN-CTR (UMIN000016086, registration date December 30, 2014).

Abstract
The current study presents the case of a 66-year-old male presenting with fever and chest pain. Chest enhanced computed tomography scanning revealed a mass shadow in the right upper lobe with chest wall invasion. 18-Fluorodeoxyglucose-positron emission tomography (FDG-PET) identified the localized uptake of the mass lesion in the right upper lobe, in addition to diffuse uptake by the bone marrow. The laboratory data on admission revealed marked leukocytosis and an elevated C-reactive protein level (CRP). Serum concentrations of granulocyte colony-stimulating factor (G-CSF) and interleukin 6 were increased. Based on a clinical diagnosis of non-small cell lung cancer (c-T3N0M0 stage IIB), the patient underwent right upper lobectomy with chest wall resection. The histological examination showed a pulmonary pleomorphic carcinoma. Immunohistochemical analysis of the resected tumor tissues revealed positive staining for G-CSF. The patient's high-grade fever, leukocytosis, and elevated CRP level rapidly subsided following the resection. This confirmed that the tumor was a G-CSF-producing pulmonary pleomorphic carcinoma. Five months after the resection, the diffuse FDG uptake in the bone marrow was absent, even with the presence of a small pulmonary metastasis and marginal serum G-CSF elevation. Diffuse FDG uptake in bone marrow induced by G-CSF producing pleomorphic carcinoma must be taken into consideration, in order for it not to be misinterpreted as diffuse bone marrow metastases or hematologic malignancy.

Abstract
Background Primary pulmonary mucosa-associated lymphoid tissue (MALT) lymphoma is a low-grade B cell lymphoma that is a type of non-Hodgkin lymphoma and a type of primary pulmonary malignant lymphoma. MALT lymphomas affecting the lung show various findings on chest computed tomography, which range from typical nodules or areas of consolidation to findings that are extremely rare in pulmonary MALT lymphomas, such as pure ground-glass opacities throughout the lung. Case presentation A 35-year-old woman was found to have a few shadows with ground glass opacities on chest computed tomography (CT) in 2012. A shadow in right S10 that was initially very small increased in size over time, and was 14 × 8 mm in 2015. Other shadows also appeared. Because lung adenocarcinoma was suspected, the patient underwent video-assisted thoracoscopic surgery with a right wedge resection of the lower lobe that included the largest nodule in S10 and other nodules. Histopathological examination of the right S10 and other lesions revealed small- or medium-sized lymphocyte-like cells that were located in the alveolar interseptal spaces. The alveolar walls remained intact. Immunohistochemical staining showed that tumor cells were positive for CD20, CD79a, and BCL2 expression. The lesions were diagnosed as extranodal marginal zone B-cell lymphoma of MALT. Conclusions We think that the ground glass opacities on CT were accounted for by MALT lesions that contained intact alveolar air spaces. The patient has remained well during 12 months of follow up after surgery. Although she did not receive chemotherapy because the MALT lymphoma lesions have been stable without progression, the patient is kept under close observation because of potential progression of the disease.

Abstract
A 37-year-old female smoker without a history of exposure to asbestos was referred to our hospital with persistent pericardial effusion. Chest computed tomography imaging examination revealed an irregular thickened pericardium with large amounts of pericardial effusion and a small pleural effusion. Fluorodeoxyglucose (FDG) positron emission tomography imaging demonstrated intrapericardial FDG accumulation. Blood tests revealed an increase in serum mesothelin levels. Examination of a surgically resected specimen revealed a grayish-white thickening of the pericardium, with a straw-colored mucinous pericardial effusion. Histopathological examination confirmed the diagnosis of epithelioid malignant mesothelioma. Although the patient's condition temporarily improved, with decreased levels of serum mesothelin during chemotherapy with carboplatin and pemetrexed, she succumbed to cardiac tamponade 18 months after the initial onset of the symptoms. Primary malignant pericardial mesothelioma (PMPM) is an extremely rare and refractory disorder. Thus, an early definitive diagnosis and timely treatment are crucial for the management of PMPM.

Abstract
We report six patients with closed flexor tendon rupture affecting the little finger, occurring secondarily to non-union of the hook of the hamate bone. The ununited fragments were separated from the basal part of the hook by more than 1 mm. The fragments were also rounded and showed marginal sclerosis. Non-union was located in the middle part of the hook in three patients, the tip in two, and the base in one. At operation, the fragments were removed in all patients. Five patients were treated by free tendon grafts using three palmaris and two plantaris grafts and one underwent tendon transfer. Postoperative total range of active motion of the little finger averaged 218° (range 185–265°). All patients returned to their original employment. This series would suggest that flexor tendon rupture can occur after fracture of the hook of the hamate bone, even when the ununited fragment is small and/or rounded.

Abstract
Acute exacerbation (AE) of idiopathic pulmonary fibrosis (IPF) is characterized by severe worsening dyspnea and high mortality. It has been proven that the serum neutrophil elastase (NE) level, in addition to the serum Krebs von den Lungen-6 (KL-6) and surfactant protein-D (SP-D) levels, was elevated in patients with IPF-AE. Glutathione (GSH) is the major antioxidant involved in cell metabolism and survival. It is also known that IPF is characterized by reduced GSH levels in bronchoalveolar lavage fluid and blood. Case 1 was a 67-year-old man who was referred to our hospital complaining of a 2-year history of progressive dyspnea on exertion (DOE). The patient was initially diagnosed with IPF, followed by inhaled N-acetylcysteine monotherapy. Two years later, left upper lobectomy with lymph node dissection was performed due to primary lung cancer, which was large-cell neuroendocrine carcinoma (pT2aN2M0, stage IIIA). Five days after lung surgery, the patient developed AE. Case 2 was a 67-year-old man who was referred to our hospital with suspected lung cancer, complaining of dry cough and DOE. The patient underwent left upper lobectomy with lymph node dissection for primary lung cancer, which was diagnosed as well-differentiated adenocarcinoma (pT2aN2M0, stage IIIA). Ten days after lung surgery, the patient developed AE. The levels of biomarkers, such as serum NE, redox balance [reduced GSH (rGSH)/oxidized GSH (GSSG)] in the blood, as well as the correlation between serial changes of these biomarkers and prognosis, were analyzed in 2 patients with postoperative IPF-AE associated with lung cancer. Interestingly, the serial changes of the serum rGSH/GSSG ratio may suggest the possibility of predicting the onset of postoperative AE and/or survival, along with serum NE levels.

Abstract
Background One cause of recurrent spontaneous pneumothorax includes overlooking bullae during a previous surgery for pneumothorax; and the identification of the culprit lesions is necessary for prevention of recurrence. Case presentation A 28-year-old man was referred to our hospital because of spontaneous right-sided pneumothorax. He underwent video-assisted thoracoscopic surgery, which did not reveal air leakage. The patient was subsequently seen at our hospital for 2 additional episodes of recurrent right-sided pneumothorax. At the third admission we observed intermittent air leakage while the patient was in the sitting position after chest drainage, and we performed surgery. An intraoperative submersion test showed air leakage dorsally from the pleural surface of S6 and a minute culprit lesion, which were not seen at the first operation and confirmed the leakage site. The area was ligated and coated with regenerated oxidized cellulose mesh and autologous blood. Conclusion In cases of pneumothorax with repeated recurrence, the best time to perform surgery on the patient with undetectable culprit lesion is the exact time that air leakage is observed.

Abstract
A 44-year-old man was admitted to our hospital with severe back pain continuing for 12 years. Computed tomography of the chest revealed a 14 mm diameter tumor with calcification located in the right seventh rib. We performed right seventh rib and sixth to seventh intercostal muscle partial resection. Microscopically, the tumor showed typical features of a schwannoma composed of Antoni A and Antoni B tissues. The tumor had positive immunohistochemical staining for S-100 protein. The pathological diagnosis was intraosseous schwannoma. The patient's severe back pain disappeared and there was no recurrence or metastasis of the tumor during a 1-year follow up.

Abstract
The syndrome of combined pulmonary fibrosis and emphysema (CPFE) has been characterized by severely impaired gas exchange and poor survival. However, the clinical features of patients with lung cancer plus CPFE have remained elusive. The present study performed a retrospective analysis to examine the clinical characteristics and outcome of surgically resected patients with lung cancer plus CPFE. Among 831 patients with primary lung cancer who underwent surgical resection, 23 patients (2.8%) were diagnosed with CPFE and 9 patients (1.1%) with solely idiopathic pulmonary fibrosis (IPF). Thirty-five patients were stratified as the solely emphysema group with adjustment of the pathological stage. The clinicopathological characteristics of patients in the CPFE group and their outcomes were evaluated and compared with those with the solely IPF or solely emphysema groups. Within the CPFE group, no significant differences in survival between patients with post-operative acute exacerbation (AE; n=3) and those without AE (n=20) were noted; however, in the solely IPF group, patients with post-operative AE (n=4) had a significantly shorter survival than those without AE (n=5; P=0.022). The 5-year survival rate of patients in the CPFE, solely IPF and solely emphysema groups was 22, 22 and 58%, respectively. Furthermore, the CPFE and solely IPF groups showed a significantly shorter survival than the solely emphysema group (P=0.001 and 0.011, respectively). In conclusion, surgically resected lung cancer patients with CPFE had poor survival, which was, in contrast to that of lung cancer patients with solely IPF, not affected by AE.

Abstract
BACKGROUND The prognosis for patients with large cell neuroendocrine carcinoma (LCNEC) of the lung is extremely poor, and optimal treatment strategies have not yet been established. To improve prognoses in patients with LCNEC, this study analyzed immunohistochemical expression and gene mutations of several known molecular targets in LCNECs and compared the expression levels of these targets with those in lung adenocarcinomas. METHODS Twenty-six patients with primary LCNEC and 40 patients with adenocarcinoma were analyzed. Excision repair cross-complementation group 1 (ERCC1), class III β-tubulin, topoisomerase I, topoisomerase II, epidermal growth factor receptor (EGFR)-L858R, and somatostatin receptor expression were evaluated by immunohistochemistry, and EGFR mutations were evaluated using direct DNA sequencing and the Scorpion-amplified refractory mutation system. RESULTS In patients with LCNEC and adenocarcinoma, positive rates of topoisomerase I, topoisomerase II, ERCC1, class III β-tubulin, EGFR-L858R, and somatostatin were 100.0% and 100.0%, 65.4% and 15.0% (p < 0.0001), 42.3% and 17.5% (p = 0.0462), 46.2% and 62.5%, 0.0% and 20.0% (p = 0.0182), and 50.0% and 5.0% (p < 0.0001), respectively. The frequencies of EGFR mutations were 0.0% and 37.5% in LCNEC and adenocarcinoma (p = 0.0002), respectively. Five-year overall survival rates were 64% in LCNEC and 91% in adenocarcinoma in stage I (p = 0.0132). Multivariate analysis showed that LCNEC histologic type was an independent prognostic factor in stage I. CONCLUSIONS LCNEC showed overexpression of topoisomerase II, somatostatin, and ERCC1. These findings suggested that it was possible to have good response to treatment with etoposide and octreotide and that LCNEC may be resistant to platinum-based therapy compared with adenocarcinoma. EGFR mutations were not observed in LCNEC. These results may indicate a favorable response to adjuvant treatments that are not typically prescribed for non-small cell lung cancer.

Abstract
Background Myelolipoma is a rare benign tumor composed of mature adipose tissue and normal hematopoietic tissue. Although surgical resection has been recommended due to the potential of progressive enlargement, the natural history of mediastinal myelolipoma has not yet been described. Herein we report a surgically resected mediastinal myelolipoma showing gradual enlargement over a period of 9 years. Case presentation A 70-year-old woman presented with a posterior mediastinal mass shadow detected by computed tomography (CT) examination. She had a medical history of sigmoidectomy for colon cancer 13 years previously. A CT scan showed a smooth, well-demarcated 2.8 × 2.1-cm paravertebral mass shadow, composed of a fat density area and a soft tissue density area, which showed gradual enlargement from a 1.6 × 1.0-cm nodule 9 years previously. This was not accompanied by chronic anemia or hematologic disease including thalassemia, and no abnormal accumulation was observed on bone marrow scintigraphy or fluoro-2-deoxyglucose positron emission tomography. With a clinical diagnosis of mediastinal myelolipoma, surgical resection was performed, and pathological examination confirmed the diagnosis. Conclusions We experienced a rare case with mediastinal myelolipoma showing gradual enlargement, with a tumor doubling time of 1,212 days.

Abstract
Background The simultaneous surgical treatment of thoracic aortic arch aneurysm (TAA) and lung carcinoma is extremely rare. Case presentation We report the simultaneous surgical treatment of TAA and squamous cell carcinoma of the lung in a 72-year-old Japanese man. We performed a one-stage operation that consisted of aortic arch replacement for aortic arch aneurysm with a 3-branched artificial vessel under separate cerebral and systemic extracorporeal circulation, and left upper lobectomy for lung cancer via a left lateral thoracotomy. Conclusions Although patients should be carefully selected for this procedure, the simultaneous surgical treatment of TAA and lung carcinoma can be performed safely.

Abstract
Background Costal exostosis is a benign condition that sometimes requires emergent surgery because of associated hemothorax; in addition, there have been cases with malignant transformation to chondrosarcoma. Here, we describe an asymptomatic patient who underwent thoracoscopic resection for primary costal exostosis. Case presentation A 16-year-old male was found to have a bow-shaped shadow on a chest X-ray. Chest computed tomography revealed a rod-like mass with a soft tissue shadow adjacent to the left fifth rib. A thoracoscopic partial resection of the left fifth rib was performed. Intraoperative findings included thickening of the pericardium near the tip of the growth and erosion of the visceral pleura of the left lung. The resected specimen was diagnosed as a primary costal exostosis based on histopathological findings. Conclusions We review the published literature on costal exostosis and discuss the surgical indications of asymptomatic cases.

Abstract
A 30-year-old man was admitted to Toho University Omori Medical Center for assessment of right chest pain and fever. Chest computed tomography (CT) revealed an anterior mediastinal tumor sized 11.0×6.0×5.0 cm, with right pleural effusion. The laboratory analysis revealed elevated white blood cell count (11,000/µl), C-reactive protein (4.1 mg/dl) and cytokeratin fragment (CYFRA; 12.7 ng/ml; normal, <2 ng/ml). The level of CYFRA in the pleural effusion was also markedly elevated (143 ng/ml). On the first day after admission (6 days after the initial CT), there was a mild regression on CT (10.0×5.5×4.4 cm; reduction rate, 26.7%), with decrease of the pleural effusion volume. A CT-guided needle biopsy was performed, but the findings were not conclusive, as most of the tissue was necrotic. Seven days later (13 days after the initial CT), a CT revealed further regression (9.5×5.4×4.2 cm; reduction rate, 34.7%) with disappearance of the pleural effusion. The patient was followed up on an outpatient basis. At 35 days after the initial CT, the tumor continued to shrink without treatment (8.0×3.6×3.0 cm; reduction rate, 73.8%) and the serum CYFRA level had decreased to 0.8 ng/ml, although it had not returned to normal levels. At 62 days after the initial CT, the patient underwent surgical resection. The resected specimen was diagnosed as thymoma (World Health Organization type B2; Masaoka classification, stage II), with prominent degeneration and necrosis. One possible cause of the spontaneous regression may be increased internal pressure, probably associated with rapid tumor growth, leading to massive necrosis with resulting chest pain, inflammatory reaction with pleural effusion and subsequent tumor regression. The serum CYFRA level may be a useful marker for the evaluation of the clinical course of thymoma with extensive necrosis.

Abstract
Background Surgery for chronic pulmonary aspergillosis is often technically risky. The choice of immediate thoracoplasty or muscle flap plombage to prevent postoperative space problems remains controversial. This study focused on the use of muscle flaps to prevent postoperative complications. Methods During an 8-year period (2004 to 2012), all patients surgically treated for chronic pulmonary aspergillosis were enrolled in this retrospective study. Concomitant intrathoracic transposition of the latissimus dorsi muscle flap has been performed since 2011. The clinical records of these patients were reviewed retrospectively. Results From 2004 to 2012, 16 patients were treated for chronic pulmonary aspergillosis. Fifteen patients received lobectomies and one had a partial resection. A preventive latissimus dorsi muscle flap was used in 6 patients (37 %). No postoperative deaths occurred. Prolonged air leaks appeared in 2 patients without muscle flaps, resulting in empyema in both. None of the patients with preventive muscle flaps suffered prolonged air leaks and subsequent empyema. In the outpatient clinic, late onset air leaks developed in 2 patients, one of whom had a lobectomy with muscle flap while the other had a lobectomy without muscle flap. Residual pleural space persisted in these two patients and Aspergillus infection later recurred. Conclusions Concomitant latissimus dorsi muscle flaps may be effective for the prevention of prolonged air leaks and subsequent empyema. Late onset air leaks are problematic.

Abstract
Background Anomalous systemic arterial supply to the normal basal lung segments is a sequestration spectrum variant (Pryce type 1) that is distinguished from pulmonary sequestration by normal bronchopulmonary and parenchymal tissues. Case presentation A 33-year-old Japanese man was referred to our hospital because of an abnormal pulmonary shadow. Computed tomography showed two aberrant arteries arising from the descending aorta and running into the lower lung lobes on each side, without any bronchial anomaly. He was diagnosed with bilateral anomalous systemic supply to the basal segments. A left thoracotomy was performed and the aberrant arteries were ligated and dissected at their origin followed by left basal segmentectomy. Simultaneous right S10 segmentectomy was performed under video-assisted thoracic surgery. Conclusion Although bilateral anomalous systemic arterial supply to the basal segments is extremely rare, knowledge of this anomaly should allow for a definitive diagnosis and appropriate therapy.

Abstract
Background Chronic pulmonary aspergillosis (CPA) has been accepted the criteria for the diagnosis of pulmonary Aspergillus infection. Whereas, either pathophysiology or signs of CPA remains still controversial. Methods In this study, we histopathologically investigated 25 specimens of CPA, surgically resected. Results 21 (84 %) of that comprised male. There were 21 cases with mild impairment of the immune system and/or a scar mostly due to old tuberculosis. There is a tendency for a negative correlation between peripheral blood white cell numbers and value level of beta-(1,3)-D-glucan. Four cases showed a granular fluorescent signal in granulation tissue surrounding the cavity without the fungal aspects itself. Conclusions In conclusion, acute inflammatory exudate along the terminal respiratory tract is most significant pathophysiolocial complication of the CPA, caused to organizing pneumonia, which derives fatal respiratory failure. In addition, the viability of fungus does not concern extension of exudative inflammation at the site of erosion along terminal airway.

Abstract
The appropriate surgical approach for a large mediastinal tumor is controversial. Median sternotomy is the standard approach for thymomas. We herein report the case of a giant thymoma, 13 cm in diameter, surgically resected via anterolateral incision. Subsequent thymectomy was performed via thoracoscopy. The resected specimen was a WHO type AB thymoma, Masaoka stage I, without capsular invasion. The anterolateral incision was less invasive and more versatile in the present case, as the incision could be extended to a hemiclamshell or posterolateral incision depending on exposure and relationship to adjacent organs and vascular structures.

Abstract
Surgical treatment for metachronous second primary lung cancer following curative resection of primary lung cancer may be challenging. Standard surgical strategies for metachronous second primary lung cancer have not yet been established. The purpose of this study was to evaluate the outcomes of patients who underwent surgical resection for metachronous second primary lung cancer. A total of 12 patients surgically treated for metachronous second primary lung cancer ≥5 years after the initial surgery were retrospectively analyzed. The overall 5-year survival after the second surgery was 56.5%. There was no operative mortality. Patients with T1aN0M0 metachronous second primary lung cancer experienced a significantly higher 5-year overall survival rate compared with other patients (100 vs. 26.7%, respectively; P=0.0336). Among patients who underwent sublobar resection, all 3 patients with T1aN0M0 disease remained alive at the last follow-up, while 4 of the 5 patients (80%) with non-T1aN0M0 disease had developed recurrence. Surgery for metachronous second primary lung cancer may be safely performed. Early-stage metachronous second primary lung cancer was associated with a good prognosis, even among patients who underwent sublobar resection. Early detection of metachronous second primary lung cancer with close long-term follow-up following initial surgery may improve surgical outcomes.

Abstract
Although it has been reported that oxytocin stimulates lipolysis in adipocytes, changes in the expression of oxytocin receptor (OTR) mRNA in adipogenesis are still unknown. The present study aimed to investigate the expression of OTR mRNA during adipocyte differentiation and fat accumulation in adipocytes. OTR mRNA was highly expressed in adipocytes prepared from mouse adipose tissues compared to stromal-vascular cells. OTR mRNA expression was increased during the adipocyte differentiation of 3T3-L1 cells. OTR expression levels were higher in subcutaneous and epididymal adipose tissues of 14-week-old male mice compared to 7-week-old male mice. Levels of OTR mRNA expression were higher in adipose tissues at four different sites of mice fed a high-fat diet than in those of mice fed a normal diet. The OTR expression level was also increased by refeeding for 4 h after fasting for 16 h. Oxytocin significantly induced lipolysis in 3T3-L1 adipocytes. In conclusion, a new regulatory mechanism is demonstrated for oxytocin to control the differentiation and fat accumulation in adipocytes via activation of OTR as a part of the hypothalamic-pituitary-adipose axis.

Abstract
AIM The present pilot study assessed the usefulness of nanofluidic digital polymerase chain reaction (PCR) arrays in epidermal growth factor receptor (EGFR)-mutant lung adenocarcinoma after tyrosine kinase inhibitor (TKI) resistance. PATIENTS AND METHODS We enrolled 12 patients with primary lung adenocarcinoma with sensitive EGFR mutation-confirmed T790M status by re-biopsy after TKI resistance. Nanofluidic digital PCR arrays were used to quantify T790M in genomic DNA from the pre-treatment primary site and in serum cell-free DNA (cfDNA). RESULTS On digital PCR, quantified T790M at the pre-treatment primary site was higher in re-biopsy-positive T790M patients (n=4) than in re-biopsy-negative patients (n=8) (0.78%±0.36% vs. 0.07%±0.09%, p<0.01). T790M at the pre-treatment primary site correlated with progression-free survival (PFS) after gefitinib therapy (r=0.67, p=0.016). CONCLUSION Use of digital PCR to quantify T790M at the primary site of EGFR-mutant lung adenocarcinoma predicted T790M emergence in re-biopsies after TKI resistance and PFS after gefitinib therapy.

Abstract
An 85-year-old man presented with diplopia and anterior mediastinal tumor that had enlarged during the preceding 4-year period. Computed tomographic chest imaging showed an irregularly shaped mass comprising two nodules (diameter, 4 cm) with calcification. Suspecting thymoma, we performed video-assisted thoracoscopic thymectomy. The resected specimen showed deposition of homogeneous eosinophilic and hyalinized material around the vessel wall in thymic tissue, and it stained positively for anti-λ antibody, indicating localized AL amyloidosis. There was no other organ dysfunction or symptoms and no evidence of systemic amyloidosis. Diplopia resolved immediately after thymectomy; however, the connection of diplopia with amyloidoma and thymic tissue remains uncertain.
