Abstract
Although primarily studied through the lens of community ecology, phenomena consistent with priority effects appear to be widespread across many different scenarios spanning a broad range of spatial, temporal, and biological scales. However, communication between these research fields is inconsistent and has resulted in a fragmented co-citation landscape, likely due to the diversity of terms used to refer to priority effects across these fields. We review these related terms, and the biological contexts in which they are used, to facilitate greater cross-disciplinary cohesion in research on priority effects. In breaking down these semantic barriers, we aim to provide a framework to better understand the conditions and mechanisms of priority effects, and their consequences across spatial and temporal scales.

Abstract
A 38-year-old male, he was diagnosed with a giant pulmonary bulla occupying 2/3 of the right thoracic cavity on chest computed tomography( CT). The preoperative pulmonary function was unfavorable, so bullectomy of right upper lobe with video-assisted thoracoscopic surgery( VATS) was performed. The outpatient follow-up was completed at 6 months after surgery. However, one year and eleven months postoperatively, the patient returned to the clinic complaining of dyspnea. Chest X-ray and CT showed a recurrence of a giant emphysematous bulla in the right upper lobe. Two years and three months after the initial surgery, the recurrent giant bulla was resected by right upper lobectomy with VATS. About four years after the reoperation, no recurrence of giant pulmonary bulla has been seen. Although there are some reports on surgical treatment and results of giant pulmonary bulla, there are few reports on recurrent cases, so we report this case.

Abstract
CASE PRESENTATION A 65-year-old man experienced a cough and mild hemoptysis suddenly one morning. He was prescribed tranexamic acid and carbazochrome salicylate by the local clinic at the first visit, and his hemoptysis stopped. However, 2 days later, he experienced recurrent hemoptysis that was prolonged intermittently. He had slight dyspnea and chest discomfort, but no other symptoms, such as sputum, fever, or chest pain. He was referred to our hospital for further assessment of hemoptysis. He had experienced mild hemoptysis of unknown causes 8 years earlier without recurrence until this episode. He had bronchial asthma that was treated with an inhaled corticosteroid and hypertension and hyperuricemia that were untreated with medication. He had no known allergies or family history of lung disease. He did not smoke. The patient denied alcohol consumption, any recent travel, or exposure to TB.

Abstract
BACKGROUND Obesity leads to an increase in the incidence and severity of asthma. Adipokines, such as leptin, secreted by adipocytes induce systemic inflammation, causing airway inflammation. We previously reported that leptin activates both inflammatory and structural cells, including lung fibroblasts. However, little is known about the differential leptin expression and responsiveness to leptin in asthmatic individuals and healthy controls (HC). In this study, we investigated the expression and origin of leptin in asthmatic airways. We also compared the effect of leptin on asthmatic and HC fibroblasts. METHODS Lung specimens from asthmatic and non-asthmatic patients were analyzed by immunohistochemical staining using anti-leptin and anti-CD163 antibodies. Leptin mRNA and protein levels in human monocytes were detected by real-time PCR and western blotting and ELISA, respectively. We used flow cytometry to analyze asthmatic and HC lung fibroblasts for leptin receptor (Ob-R) expression. Further, we determined cytokine levels using cytometric bead array and ELISA and intracellular phosphorylation of specific signaling molecules using western blotting. RESULTS Asthma specimens displayed accumulation of leptin-positive inflammatory cells, which were also positive for CD163, a high-affinity scavenger receptor expressed by monocytes and macrophages. Leptin expression was observed at both transcript and protein levels in human blood-derived monocytes. No significant differences were observed between asthmatic and HC lung fibroblasts in Ob-R expression, cytokine production, and intracellular phosphorylation of p38 mitogen-activated protein kinase. CONCLUSIONS Our findings reveal similar responsiveness of control and asthmatic fibroblasts to leptin. However, the accumulation of inflammatory leptin-producing monocytes in the airway may contribute to the pathogenesis of asthma.

Abstract
Secretory immunoglobulin A plays an important role in the protection against exogenous pathogens and antigens, but it has also been reported to have pathogenic potential. We previously found that secretory immunoglobulin A accumulated in the peripheral lungs during idiopathic pulmonary fibrosis and that transferrin receptor/CD71 was partially involved in secretory immunoglobulin A-induced inflammatory cytokine production in A549 cells. This study aimed to identify the receptor responsible for the induction of cytokine production by secretory immunoglobulin A-stimulated airway epithelial cells. To this end, immunoprecipitation followed by time-of-flight mass spectrometry and peptide mass fingerprinting were performed and Annexin A2 was detected as a novel receptor for secretory immunoglobulin A. Enzyme-linked immunosorbent assay demonstrated binding of secretory immunoglobulin A to Annexin A2, and flow cytometry showed robust expression of Annexin A2 on the surface of BEAS-2B cells, A549 cells, and normal human bronchial/tracheal epithelial cells. Experiments in A549 cells using Annexin A2 small interfering RNA and neutralizing antibodies suggested that Annexin A2 was partially involved in the production of interleukin-8/CXCL8 and C-C motif chemokine ligand 2/monocyte chemoattractant protein-1 induced by secretory immunoglobulin A. Immunohistochemistry using lung sections revealed clear expression of Annexin A2 on airway epithelial cells, although the staining remained equivalent in idiopathic pulmonary fibrosis, asthma, and healthy control lungs. In conclusion, we identified that Annexin A2 expressed in airway epithelial cells is a novel receptor for secretory immunoglobulin A, which is involved in cytokine synthesis.

Abstract
The number of cases with Mycobacterium avium and Mycobacterium intracellulare lung diseases (Mycobacterium avium complex lung disease [MACLD]) are increasing globally. Lung cancer can sometimes present as a comorbidity with MACLD; however, the clinical presentation and outcomes of comorbid MACLD following lung cancer resection remain unclear. Therefore, we retrospectively assessed 17 patients with MACLD undergoing lung cancer resection to determine the impact of lung cancer surgery on comorbid MACLD. Of the 17 patients, Mycobacterium avium and Mycobacterium intracellulare were present in 15 and 2 patients, respectively; 14 patients had stage I lung cancer and underwent lobectomy. Ten patients were postoperatively observed for MACLD without any further intervention, five patients underwent additional resection for conspicuous MACLD lesions, and the remaining two patients underwent complete resection for MACLD and lung cancer within the same lobe followed by rifampicin, ethambutol, and clarithromycin (RECAM) therapy. Seven patients exhibited postoperative MACLD exacerbation, six of whom developed exacerbation in the operated ipsilateral residual lobes. Six of these seven patients received RECAM, three of whom (43%) subsequently exhibited improvement. Attention should be paid to MACLD exacerbation during postoperative follow-up, especially in ipsilateral lobes. Although RECAM therapy may be beneficial in alleviating MACLD exacerbation, further investigation is warranted to validate these results.

Abstract
BACKGROUND Aspergillus spp. is identified morphologically without antifungal susceptibility tests (ASTs) in most clinical laboratories. The aim of this study was to examine the clinical impact of the morphological identification of Aspergillus spp. to ensure the adequate clinical management of Aspergillus infections. PATIENTS/METHODS Aspergillus isolates (n = 126) from distinct antifungal treatment-naïve patients with aspergillosis were first identified morphologically, followed by species-level identification via DNA sequencing. An AST for itraconazole (ITC) and voriconazole (VRC) was performed on each Aspergillus isolate. RESULTS Based on the genetic test results, morphology-based identification was accurate for >95% of the isolates at the species sensu lato level although the test concordance of Aspergillus spp. with low detection rates was low. The rates of cryptic species were found to be 1.2% among the isolates of A. fumigatus complex and 96.8% in the A. niger complex. Cryptic species with lower susceptibilities to antifungal drugs than sensu stricto species among the same Aspergillus section were as follows: The A. lentulus (n = 1) isolates had low susceptibilities to azoles among the A. fumigatus complex species (n = 86), and A. tubingensis isolates (n = 18) exhibited lower susceptibility to azoles among the A. niger complex species (n = 31). CONCLUSION Diagnostic accuracy was high at the A. fumigatus and A. niger complex level. However, in the presence of cryptic species, a solely morphological identification was insufficient. Particularly, ITC and VRC might be inappropriate for aspergillosis treatment when the A. niger complex is identified morphologically because it is possible that the Aspergillus isolate is A. tubingensis.

Abstract
Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) are a first-line treatment for patients with nonsmall-cell lung cancer harboring EGFR mutations. We report a 65-year-old Japanese woman with nonsmall-cell lung cancer taking an EGFR-TKI who visited the emergency department with acute nausea and vomiting. Imaging studies demonstrated an incarcerated diaphragmatic hernia. Urgent diagnostic surgery revealed a gap in the diaphragm acting as a hernial orifice, where a metastatic tumor was detected. We consider that regression of the diaphragmatic metastasis by EGFR-TKI therapy resulted in perforation of the diaphragm, causing the diaphragmatic hernia. Gastrointestinal adverse events, e.g. nausea, vomiting and diarrhea, are common during EGFR-TKI treatment. However, this case suggests that in patients with diaphragmatic metastasis, we should consider the rare possibility of diaphragmatic perforation and a subsequent hernia.

This study aimed to investigate whether the species of Aspergillus section Nigri isolated from the respiratory tract vary depending on clinical diagnosis. Forty-four Aspergillus section Nigri isolates isolated from the lower respiratory tracts of 43 patients were collected from February 2012 to January 2017 at the National Hospital Organization (NHO) Tokyo National Hospital. Species identification was carried out based on β-tubulin gene analysis. Drug susceptibility tests were performed according to the Clinical and Laboratory Standards Institute (CLSI) M38 3rd edition, and the clinical characteristics were retrospectively reviewed. A. welwitschiae was isolated most frequently, followed by A. tubingensis. More than half of the A. tubingensis isolates exhibited low susceptibility to azoles in contrast to only one A. welwitschiae isolate. Approximately three quarters of the patients from whom A. welwitschiae was isolated were diagnosed with colonization, whereas more than half the patients from whom A. tubingensis was isolated were diagnosed with chronic pulmonary aspergillosis (CPA). More attention needs to be given to the drug choice for patients with CPA with Aspergillus section Nigri infection because A. tubingensis, which was found to be frequently azole-resistant, was the most prevalent in these patients.

Abstract
The prevalence of azole-resistant Aspergillus fumigatus (ARAF) among chronic pulmonary aspergillosis (CPA) patients treated with azoles in Japan is unknown. The aim of this study was to determine the detection rate of ARAF in isolates from CPA patients who were treated with azoles for varying durations. The potential mechanism of acquiring resistance was examined by sequencing cyp51A and hmg1, two genes associated with ARAF. A. fumigatus isolates (n = 120) were collected from CPA patients (n = 104) between February 2012 and February 2019, at National Hospital Organization Tokyo National Hospital. The isolates were tested for susceptibility to the azole drugs itraconazole (ITCZ) and voriconazole (VRCZ). The detection rate of ARAF among all isolates was 8.3% (n = 10). Of the 10 resistant isolates, eight were ITCZ-resistant and five were VRCZ-resistant. Among 47 isolates obtained from 36 CPA patients who were treated with ITCZ (for an average of 256 days) and/or VRCZ (for an average of 29 days), the resistance rates were 17.0% and 10.6%, respectively. In addition, 46.2% of 13 isolates obtained from CPA patients with ongoing azole treatment at the time of antifungal therapy failure were resistant to azoles. Among the 10 ARAF isolates, a point mutation was detected in cyp51A in seven isolates and in hmg1 in two isolates. ARAF was detected at a high rate in CPA patients, particularly in those with ongoing long-term azole treatment, at the time of azole antifungal therapy failure.

Abstract
Ovarian cancer is a critically lethal gynecologic malignancy. More than 80% of patients with ovarian cancer have relapses within 5 years after initial treatment. However, recurrence from ovarian cancer more than 20 years later is extremely rare. We report a case of a 67-year-old female with mediastinal metastasis from ovarian cancer 29 years after initial gynecologic surgery and chemotherapy.

Abstract
Active tuberculosis is an important complication in Japanese lung cancer patients. We studied the generation-wise trend of latent tuberculosis infection (LTBI) among lung cancer patients. We analyzed background data including birth year, lung cancer status, and interferon-gamma release assay (IGRA) data of lung cancer patients who were admitted to National Hospital Organization Tokyo National Hospital from 2010 to 2016. Of the 1450 cases, 7 showed active tuberculosis and 45 had previous tuberculosis. Of the remaining 1398 patients, 795 underwent IGRAs and 120 (15%) of them were found to have LTBI. Patients with LTBI were older (p = 0.0005), and the proportion of smokers was also higher in this group (p = 0.0159) than among those without LTBI. LTBI incidence decreased from 33% among patients born in the 1920s to 21%, 15%, 9.8%, and 5.1% among those born in the 1930s, 1940s, 1950s, and after 1960, respectively. A significant decrease in the smoking adjusted risk ratio was also observed with every generation (p < 0.0001). Our study suggests that the total number of patients with active tuberculosis comorbid with lung cancer will greatly decrease in the future in Japan. However, owing to recent improvements in lung cancer prognosis due to advances in cancer medication, careful monitoring for active tuberculosis development may be required in lung cancer patients with LTBI.

Abstract
OBJECTIVES The number of octogenarian lung cancer patients undergoing radical surgery has been increasing recently. However, knowledge regarding the risk factors for postoperative complications and reliable predictive factors for long-term survival is limited. This study aimed to investigate the risk factors of postoperative complications, and reliable prognostic factors, in lung cancer patients older than 80 years. METHODS Lung cancer patients aged 80 years or older who underwent radical surgery were retrospectively studied; a multi-institutional analysis was conducted from January 1998 to December 2015. Preoperative and postoperative clinical data, including age, gender, smoking history, body mass index, respiratory function, Charlson Comorbidity Index, Glasgow Prognostic Score, surgical procedure, cancer histology, clinical and pathological stage, surgical result and survival time, were collected. RESULTS A total of 337 patients, comprising 216 (64.1%) men and 121 (35.9%) women were enrolled. The median age was 82 (range 80-92) years. Of the 337 patients, 205 (60.8%) had preoperative comorbidities. Postoperative complications were observed in 119 (35.3%) patients; postoperative mortalities occurred in 6 (1.8%) patients. Univariate and multivariate analyses showed that male gender (P = 0.01) and operation time (P = 0.047) were associated with postoperative complications; in contrast, pathological Stage III (P < 0.001), male gender (P = 0.01), Charlson Comorbidity Index ≥2 (P = 0.03) and Glasgow Prognostic Score = 1/2 (P = 0.04) were independent prognostic factors for overall survival. CONCLUSIONS The risk factors for postoperative complications (male gender and operation time) and the predictive factors affecting long-term survival (male gender, Charlson Comorbidity Index, Glasgow Prognostic Score and P-stage) should be taken into account for the effective management of patients older than 80 years with lung cancer, undergoing surgery.

Abstract
Lung fibroblasts participate in the pathogenesis of respiratory diseases, including lung cancer and pulmonary fibrosis. Although fibroblasts are ubiquitous constituents of various organs, their cellular diversity among different organs has been poorly characterized. Here, we aimed to investigate the distinct gene signature of lung fibroblasts that represents its pulmonary origin and the underlying gene regulatory networks. Promoter-level differential expression analysis by cap analysis of gene expression (CAGE) sequencing revealed distinct gene expression patterns of fibroblasts derived from different anatomical sites and identified 88 coding genes with higher expression in lung fibroblasts relative to other fibroblasts. Multiple key transcription factors important for lung mesenchyme development, including the T-box transcription factors TBX2, TBX4, and TBX5 were enriched in this lung-specific signature and were associated with super-enhancers. TBX4 showed highly specific expression in lung fibroblasts and was required for cell proliferation and collagen gel contraction capacity. Transcriptome analysis revealed that TBX4 could broadly regulate fibroblast-related pathways and partly contribute to super-enhancer-mediated transcriptional programs. Of pathological importance, lung fibroblast-specific genes were globally downregulated in lung cancer-associated fibroblasts (CAFs). Notably, TBX2, TBX4, and TBX5 were downregulated and hypermethylated in lung CAFs, suggesting an association between epigenetic silencing of these factors and phenotypic alteration of lung fibroblasts in cancer. Our study highlights the importance of T-box transcription factors, especially TBX4, and super-enhancers in the roles of lung fibroblasts in pulmonary physiology and pathogenesis.

Abstract
OBJECTIVE Quaternary ammonium cationic surfactants (ACSs) and N-[3-alkyl(12,14)oxy-2-hydroxypropyl]-l-arginine hydrochloride (N-AOHPA) were used to emulsify silicone. The potential of the resulting emulsions in hair conditioning products was investigated. METHODS The emulsions were prepared using a homogenizer and/or high-pressure homogenizer. ACSs and N-AOHPA were used as silicone emulsifiers. The stability of the emulsions was evaluated by measuring particle sizes, creaming fractions, polydispersity indexes and zeta potentials. Moreover, the N-AOHPA-stabilized emulsion was compared with the ACS-stabilized emulsion to evaluate the adsorption amount of silicone on healthy and bleached hair surfaces and the inhibitory effects on amino acid dissolution from bleached hair. The adsorption site of the N-AOHPA-stabilized emulsion was observed using a scanning electron microscope. RESULTS For all surfactants, the silicone emulsions prepared using the high-pressure homogenizer were more stable than those prepared using the homogenizer. When N-AOHPA was used as the surfactant, the silicone emulsion was especially stable. Furthermore, the d50 value of the N-AOHPA-stabilized emulsion was smaller than that of the ACS-stabilized emulsion. The adsorption behaviour of the silicone droplets in the different emulsions varied depending on the nature of the surfactant and the preparation method. The amount of ACS-stabilized silicone adsorbed on healthy hair was higher than that adsorbed on bleached hair, especially when the emulsion was prepared using the homogenizer. In contrast, the amount of N-AOHPA-stabilized silicone adsorbed on bleached hair was high, and no differences were observed between the N-AOHPA-stabilized emulsions prepared using the homogenizer and high-pressure homogenizer. The emulsified droplets, especially the N-AOHPA-stabilized droplets prepared using the high-pressure homogenizer, prevented amino acid dissolution from bleached hair. It was concluded that the silicone droplet adsorption site affected the dissolution process because the small N-AOHPA-stabilized droplets adsorbed at cuticle edges. CONCLUSION This study shows that N-AOHPA has good potential for use as an emulsifier in products used for improving the condition of damaged hair.

Abstract
Retroperitoneal leiomyosarcoma is a relatively rare and aggressive tumor. Because of its rarity, it is difficult to arrive at a definite diagnosis preoperatively and to design an effective strategy. Here the authors report a case of peritoneal leiomyosarcoma in which diagnosis was difficult because the clinical course resembled that of ovarian cancer. A 77-year-old woman diagnosed with ovarian cancer underwent laparotomy. The excised tumor contained a necrotic polypoid mass that histologically displayed the features of leiomyosarcoma. The patient received adjuvant chemotherapy with a combination of gemcitabine and docetaxel but died two months after surgery owing to the aggressive behavior of the tumor. Because the preoperative diagnosis in this case was ovarian cancer, arriving at a treatment strategy assuming peritoneal leiomyosarcoma was difficult. If complete surgical resection of tumor is not performed, as in the present case, the prognosis can be extremely poor.

Abstract
The aim of this analysis was to investigate the onset time and significance of maximum volume of polyhydraminios and whether the tter was associated with causes. This was a retrospective cohort study between 2012 and 2014. A total number of 68 singleton pregancies were analyzed. Gestational age at onset of polyhydramnios was 30.0 ± 2.8 (25-36) weeks in maternal factor, 30.0 ± 3.5 (25- 7) weeks in fetal factor, and 32.3 ± 2.0 (27-37) weeks in idiopathic factor. Median of maximum amniotic fluid index (AFI) was gnificantly late onset in idiopathic factor. Diabetes, gestational or pre-existing, was present in all of women (ten cases) in maternal facror. Higher AFI was found to be associated with an increased frequency of prenatally detected congenital anomalies. Abnormal fetal kary- type noted in 18/45 (40%) cases of polyhydramnios. Polyhydramnios diagnosed on ultrasound requires further maternal and fetal iagnostic tests.

Abstract
This was a retrospective cohort study between 2002 and 2011. A total number of 150 singleton pregnancies with preterm premature rupture of membranes (PROM) (before 34 weeks) were analyzed. Histological chorioamnionitis (Blanc grade III) was significantly increased over three days from onset of premature rupture of membranes. The positive relationship was strengthened (odds ratios, 3.5; 95% confidence intervals, 1.5-5.2) over three days from onset of preterm PROM. PROM is a risk factor important for histological chorioamnionitis. To avoid neonatal infection, early termination is recommended in preterm PROM patients.

Abstract
The authors here report a 54-year-old (gravida 0, para 0), who claimed to have had her menarche at age 13 and menopause at 52 years. Two months prior to presentation, the subject first noticed a hard but elastic fist-sized mass in the left inguinal region that gradually grew, causing pressure-related pain. Although the external genitalia appeared female, the vagina was short and blind-ending, and no uterus or ovaries were identified on transvaginal ultrasound. Chromosome banding results (G-band method) showed 46XY. Laparoscopy revealed no traces of a vestigial uterus or ovaries; thus, based on the appearance of the external genitalia, a diagnosis of testicular feminization syndrome was made. Pathological testing of the palpable mass led to a diagnosis of seminoma with Leydig cell hyperplasia. Thus, in this case, the development of a seminoma in an undescended testis led to the detection of testicular feminization syndrome.

Abstract
PURPOSE OF INVESTIGATION This study aimed to estimate the effectiveness of hysteroscopic myomectomy for symptomatic submucous uterine fibroids and to identify prognostic factors for persistent or recurrent symptoms. MATERIALS AND METHODS A total of 237 patients who underwent hysteroscopic myomectomy were divided into three groups according to the classification of the European Society for Gynaecological Endoscopy: Type 0 (n=116), Type I (n=97), and Type II (n=24). Medical records and videotape records of all patients were retrospectively reviewed. RESULTS Improvement of symptoms was achieved in 100% of Types 0 and I, and 66.7% of Type II. The five-year cumulative symptom-free rates after hysteroscopic myomectomy were 96.7% ± 1.9%, 87.8% 6.7%, and 44.5% ± 12.7% in Types 0, I, and II, respectively. The mean symptom-free periods were 46.2 ± 2.6, 47.7 ± 2.7, and 24.7 ± 6.3 months in Types 0, I, and II, respectively. Logistic regression analysis showed that co-existence of other myomas and Type II were independent prognostic factors for recurrence of symptoms. CONCLUSION Type I fibroids are a good indication for hysteroscopic myomectomy. In Type II, some patients feel that their symptoms improve, but this curative effect could be temporary.

Abstract
Introduction: The incidence of Mycobacterium avium complex (MAC)-positive respiratory specimen cultures and MAC lung disease (MACLD) is increasing worldwide. This retrospective study aimed to assess the association between MAC culture-positive bronchoscopy specimens and lung cancer. Materials and Methods: The medical records of 1382 untreated lung cancer patients between 2003 and 2011 were collected using our hospital database. Of them, records for 1258 that had undergone bronchoscopy together with sampling for mycobacterial culture were reviewed. Patient characteristics were compared between those with MAC-positive/other nontuberculous mycobacteria (NTM)-negative bronchial washings and those with MAC-negative/other NTM-negative bronchial washings. Patients with MAC-positive lung cancer were cross-sectionally divided into MACLD and non-MACLD groups, and their features were assessed. Follow-up data for patients with lung cancer but without MACLD were reviewed for subsequent development of MACLD. Results: Of the 1258 patients with lung cancer, 25 (2.0%) had MAC-positive/other NTM-negative bronchial washings. The proportion of women (52% vs 30%; P = 0.0274) and patient age (72 years vs 69 years; P = 0.0380) were significantly higher in the MAC-positive/other NTM-negative lung cancer group (n = 25) than in the MAC-negative/other NTM-negative lung cancer group (n = 1223). There were 10 patients with lung cancer and MACLD and 15 without MACLD; significant differences in patient characteristics were not found between the two groups, and none of the 15 patients without MACLD subsequently developed MACLD. Conclusion: MAC culture-positive bronchial washing is positively associated with lung cancer. Female sex and advanced age, but not lung cancer characteristics, were found to be associated with MAC infection in patients with lung cancer.

Abstract
The present authors analyzed patients' backgrounds and pre-surgical findings to clarify the risk factors of rupture of fallopian tubal pregnancy. The surgical findings 113 cases were clearly diagnosed as fallopian tubal pregnancy with or without rupture. Twenty-six cases of fallopian tubal pregnancy were ruptured and 87 cases were not ruptured at the time of operation. The risk factors of fallopian tubal rupture were assessed by Chi-square for independence test and multiple regression analysis. Obesity (BMI over 26), prior birth history, social welfare entitlement, ultrasonography findings of fetal heart movement, and pre-surgical serum beta-hCG level more than 3,000 mIU/ml patient were significantly higher risk in fallopian tubal rupture. Fertility treatment patient were at significantly lower risk for fallopian tubal rupture. Higher beta-hCG levels, especially >3,000 mIU/ml is associated with increased risk of fallopian tubal rupture in ectopic pregnancy.

Abstract
OBJECTIVES Chronic pulmonary aspergillosis (CPA) is an emerging complication after lobectomy for lung cancer. This retrospective study aimed to determine the incidence, main risk factors and clinical features of postoperative CPA in lung cancer patients. METHODS This study included lung cancer patients treated by lobectomy and with no previous history of thoracic surgery or coexistent aspergillosis at the time of surgery. The cumulative incidence of CPA was determined using death as a competing risk. Furthermore, the identified lung cancer patients were divided into CPA and non-CPA groups to compare their preoperative clinical features and to identify the risk factors of postoperative CPA by univariable and multivariable analyses. We also analysed the clinical features of CPA patients after diagnosis. RESULTS We included 475 lung cancer patients. Of these, 17 patients (3.6%) developed CPA after the lobectomy. The cumulative postoperative incidence rate of CPA was 2.3% [95% confidence interval (CI), 0.8-3.8%] at 5 years and 7.9% (95% CI, 3.0-13.0%) at 10 years. There were significantly more men (P = 0.007), smokers (P = 0.002) and comorbid chronic obstructive pulmonary disease (COPD) (P = 0.008) and interstitial lung disease (ILD) (P = 0.009) patients in the CPA group than in the non-CPA group. Multivariable analysis identified comorbid COPD (P = 0.0019) and ILD (P = 0.0003) as significant risk factors. An antifungal treatment response was obtained in 6 patients (35%). The 1-year survival rate was 47% (follow-up periods, interquartile range: 3-78 months), and 5 of the total of 11 deaths were due to CPA. CONCLUSIONS Through the present retrospective study, CPA seems to be a common sequel to lobectomy in lung cancer patients, and COPD and ILD represent strong risk factors of postoperative CPA. Because of the poor clinical outcome of lung cancer patients who develop CPA after lobectomy, careful follow-up using several examinations and chest radiographs to make CPA diagnosis may be essential.

Abstract
A first sharp diffraction peak (FSDP) is observed in the X-ray total structure factor of a molten mixture of RbCl-AgCl, while both pure melts of RbCl and AgCl do not exhibit FSDP individually. Molecular dynamics simulations were performed to investigate the origin of the FSDP with the polarizable ion model (PIM). Coexistence of covalent Ag-Cl and ionic Rb-Cl bonds leads the system to evolve intermediate range ordering, which is simulated by introducing the induced polarization in different ways between Ag-Cl with fully polarizable treatment based on Vashishta-Raman potential and Rb-Cl with suppression over-polarization in the nearest neighbor contribution based on Born-Meyer potential. The partial structure factors for both the Ag-Ag and Rb-Rb correlations, SAgAg(Q) and SRbRb(Q), show a positive contribution to the FSDP, while SAgRb(Q) for the Ag-Rb correlation exhibits a negative contribution, indicating that Ag and Rb ions are distributed in an alternating manner within the intermediate-range length scale. The origin of the intermediate-range chemical ordering of cations can be ascribed to the preferred direction of the dipole moments of anions in the PIM.

Abstract
A 54-year-old female who was started on continuous ambulatory peritoneal dialysis( CAPD) for endstage renal disease secondary to focal developed 2 pleuroperitoneal communications. At first, she developed chest pain and cough on the day following introduction. A 99m-technetium-macroaggregated albumin (99mTc-MAA) radionuclide scan showed a communication between the abdomen and the right pleural cavity. We diagnosed a right pleuroperitoneal communication. Four months later, she developed similar symptoms and was diagnosed with a left pleuroperitoneal communication. Video-assisted thoracoscopic surgery was performed for each lesion. However, the communications were detected using different methods. During the 1st surgery, the communication was detected using peritoneal dialysis fluid containing indigocarmine introduced through a CAPD catheter. During the 2nd surgery, the communication was detected by pneumoperitoneum. With regards to diaphragmatic pressure regulation, pneumoperitoneum was more rapid and convenient, so pneumoperitoneum was considered more effective for the identification and treatment of pleuroperitoneal communications. Diaphragmatic plication and pleurodesis with polyglycolic acid felt and fibrin glue on both sides were performed. No recurrence of hydrothorax was detected after treatment.

Abstract
Experimental demonstration of multi-charged heavy ion acceleration from the interaction between the ultra-intense short pulse laser system and the metal target is presented. Al ions are accelerated up to 12 MeV/u (324 MeV total energy). To our knowledge, this is far the highest energy ever reported for the case of acceleration of the heavy ions produced by the <10 J laser energy of 200 TW class Ti:sapphire laser system. Adding to that, thanks to the extraordinary high intensity laser field of ∼10(21) W cm(-2), the accelerated ions are almost fully stripped, having high charge to mass ratio (Q/M).

Abstract
High intensity laser-plasma interaction has attracted considerable interest for a number of years. The laser-plasma interaction is accompanied by generation of various charged particle beams, such as high-energy proton and ions with high charge to mass ratio (Q/M; same as multi-charged ions). Results of simultaneous novel measurements of electron-induced photonuclear neutrons (photoneutron), which are a diagnostic of the laser-plasma interaction, are proposed to use for optimization of the laser-plasma ion generation. The proposed method is demonstrated by the laser irradiation with the intensity of 1 × 10(21) W/cm(2) on the metal foil target. The photoneutrons are measured by using NE213 liquid scintillation detectors. Heavy-ion signal is registered with the CR-39 track detector simultaneously. The measured signals of the electron-induced photoneutrons are well reproduced by using the Particle and Heavy Ion Transport code System. The results obtained provide useful approach for analyzing the various laser based ion beams.

Abstract
An 79-year-old man underwent right upper lobectomy with mediastinal lymph node dissection for lung cancer. He was discharged without complications on postoperative day( POD) 8. However, on POD 16 he become dyspneic at home and was transported to a hospital by ambulance. Pulmonary thromboembolism (PTE) was detected by contrast-enhanced computed tomography. Anticoagulant therapy was initiated and inferior vena cava filter placement was performed.Due to its many possible clinical manifestations, early detection of postoperative PTE is difficult. Therefore prevention of PTE is thought to be more important. Intermittent application of pneumatic compression stockings and preventive anticoagulant therapy may help prevent PTE after surgery.

Abstract
A 21-year-old man with a history of bronchial asthma during childhood presented with left recurrent pneumothorax. Chest x-ray showed collapse of the left lung. Computed tomography showed hyperlucency and some bullae in the left upper lobe. Thoracoscopic bullectomy and pleurodesis were performed. Pneumothorax recurred twice, for which thoracoscopic bullectomy and pleurodesis were performed. During the third operation, pleurodesis of almost the entire left upper lobe was performed. Since this third operation, the patient has been free from recurrences of pneumothorax for three years. The lung perfusion scintigram performed during the absence of pneumothorax showed a lack of accumulation in the left upper lobe. The lung ventilation scintigram performed during the absence of pneumothorax showed low accumulation and delay of washout in the left upper lobe. These findings are compatible with Swyer-James syndrome. To prevent the recurrence of pneumothorax related to Swyer-James syndrome, some kind of procedure, such as extensive pleurodesis, is necessary.

Abstract
The information on the stability of medications is important to secure their quality. There is, however, little information about the stability of medications which assume to be kept by patients and customers. We previously showed that a delay in drug release occurs in some over-the-counter (OTC) drugs following storage in a high temperature, high humidity environment. In this study we prepared model tablet formulations containing an active ingredient and excipients to investigate the cause of this delayed release. The results reveal that delayed release occurs in preparations compounded with acetaminophen (AA) as the active ingredient and erythritol (ET) and crospovidone (CP) as excipients. In addition, ET deliquesces in a high humidity environment, then incorporates other particles during room temperature storage to form an aggregate. SEM observations and micropore distribution measurements conducted on OTC tablets that exhibit delayed release revealed that the number of intraparticle pores decreased after storage under high temperature, high humidity conditions. Thus, the delayed release by these pharmaceutical product formulations may be due to a change in the micropore structure both on the surface and within the particles, thereby decreasing the solvent infiltration pathways leading to the interior of the preparation.

Abstract
Capillary hemangiomas are often seen on the skin, mucosa, liver and other organs, but they are very rare in the lung. We report 3 cases of capillary hemangioma of the lung that presented as ground glass opacities(GGO) by computed tomography( CT). Mixed GGO was observed in 2 cases that increased in size after the follow-up period. The remaining case involved a pure GGO that was stable in size. They were suspected to be bronchioloalveolar carcinoma( BAC) based on the CT findings, and video assisted thoracoscopic surgery was performed in all 3 cases. It is difficult to distinguish capillary hemangioma from other malignant diseases such as BAC based on CT findings. As high resolution CT becomes more widely used, GGOs are becoming more frequently detected. When GGOs are detected by CT, capillary hemangiomas should be included in the differential diagnosis. Intraoperatively, an important surgical finding for capillary hemangiomas is that they became impalpable after repeated palpation. This surgical finding can be useful when identifying the region for biopsy and resection.

Abstract
Spontaneous intradural vertebral artery dissections may cause subarachnoid hemorrhage and often result in devastating damage. Increased use of noninvasive imaging studies has allowed larger numbers of patients to be diagnosed. In addition, intracranial vertebral artery dissection tends to induce multiple lesions affecting both intracranial vertebral arteries recurrently. Although unruptured dissections in this area usually have a benign nature, some authors have reported on the incidence of rupture from this lesion. Once hemorrhage from a dissecting vessel wall has occurred, it needs to be treated in the acute phase because of the high risk of rebleeding resulting in high morbidity and mortality. From December 2004 to July 2010, we managed 47 patients with spontaneous vertebral artery dissection, 31 patients were ruptured and 16 were unruptured. All patients who suffered from subarachnoid hemorrhage were treated with endovascular procedures. Most of the patients with unruptured dissection received medical therapy, but if the aneurysmal dilatation persisted or grew, surgical interventions were performed. Stenting with or without coils was deployed for 13 patients with posterior inferior cerebellar artery involvement at the site of dissection and/or were affected on the dominant side. In some patients, stenting was performed even if they were in the acute phase. For other ruptured patients, internal coil trappings were performed. Six patients died due to severe initial subarachnoid hemorrhage and one patient, who underwent stent deployment with coils for the dominant vertebral artery, with bilateral dissection continuing to the basilar artery died due to rerupture while the next additional coiling was planning. There were two cases of complications related to the intervention. During the follow-up period no bleeding occurred in any of the patients except for the previously mentioned patient. In conclusion, internal coil trapping or stent placement with or without coils was effective in preventing rebleeding of ruptured vertebral artery dissection. If the dissection is unruptured, it is necessary to detect the risk of bleeding with careful watching and when progress appears to be made, patients should be treated promptly. Stent-assisted therapy for preserving the patency of the parent artery and major branches is a promising treatment for vertebral artery dissection, even in the acute stage of subarachnoid hemorrhage. However, the risk of acute rerupture and recurrence remains even with the porous stent placement with or without coils.

Abstract
A 71-year-old man who had undergone chest wall resection and reconstruction with a Dacron mesh silicone prosthesis for chondrosarcoma 23 years previously presented with a chest wall hematoma. Since the hematoma was found to increase in size over time, we performed an operation to achieve hemostasis. Operative findings showed that the prosthesis had separated into three sheets.

Abstract
OBJECTIVES Human gammadelta T lymphocytes can recognise and kill non-small-cell lung cancer cells by Vgamma9Vdelta2 T-cell receptor and/or NKG2D. We have established large-scale ex vivo expansion of gammadelta T cells by zoledronate and interleukin-2. This pilot feasibility study evaluates the safety and potential anti-tumour effects of activated autologous gammadelta T cells administered intravenously to patients. METHODS Patients who had measurable foci of recurrent non-small-cell lung cancer were registered to undergo gammadelta T-cell immunotherapy, designed as a one-way, open, clinical research, after their informed consent. Mononuclear cells collected from peripheral blood of the patient were cultured with zoledronic acid and interleukin-2. After 2-week incubation, the gammadelta T-cell fraction was proliferated and it was intravenously reinfused to the patient. RESULTS Ten patients had undergone the gammadelta T-cell immunotherapy. They were administered autologous gammadelta T cells 3-12 times (mean=6) every 2 weeks. No patient died during the study period. Adverse events, not directly related to the immunotherapy, were observed five times in four patients (grade 3 pneumonia in two and grade 1 coldness in three). According to the Response Evaluation Criteria in Solid Tumours, neither complete nor partial response was achieved in any patient; stable disease was observed in three; and progressive disease in five at 4 weeks after six consecutive injections of during immunotherapy. The Functional Assessment of Cancer Therapy-Biologic Response Modifier scores of the patients during immunotherapy were stable or improved, except for one patient who had suffered from pneumonia. The patients were followed up after immunotherapy for 240-850 days (median=401 days). At the end of the observation, six patients were alive. CONCLUSIONS We suggest that gammadelta T-cell immunotherapy might be safe and feasible for patients with recurrent non-small-cell lung cancer.

Abstract
We report a case of iatrogenic diaphragmatic hernia following partial resection of the left lung via thoracoscopic surgery. A female in her 60s underwent partial resection of the left lung via thoracoscopic surgery on suspicion of primary lung cancer. The pathological finding was granuloma. Four months after surgery, she experienced pyrosis, and her radiograph showed a gastric bubble in the left thorax. Coronary-section computed tomography demonstrated that the gastric fundus had pushed into the left thorax. We performed elective video-assisted thoracic surgery because she did not show any symptoms. After the adhesiolysis, the herniated stomach was returned into the abdominal cavity, and the hernial orifice of the diaphragm was directly sutured. The postoperative course was uneventful, and the patient was discharged on the 12th postoperative day and is doing well. We should consider the possibility of iatrogenic diaphragmatic hernia following thoracic surgery during which an invasive technique involving the diaphragm was undertaken.

Abstract
A 60-year-old man was given a clinical diagnosis of sarcoidosis, with enlarged mediastinal and hilar lymphadenopathy by chest CT, high levels of angiotensin-converting enzyme, and gallium scintigraphy findings. After 2 years follow-up, chest CT showed that only the right superior lobe bronchial lymph node had enlarged, occluding the right B1 bronchus, but other enlarged lymph nodes had not changed in size. We performed bronchoscopy to evaluate the occlusion of the right B1 bronchus, and recognized a polypoid lesion. Transbronchial tumor biopsy specimens revealed squamous cell lung carcinoma. A right upper lobectomy and drainage of the hilar and mediastinal lymph regions were performed. Histopathological examination revealed the coexistence of squamous cell carcinoma with many non-caseating epithelioid cell granulomas in all hilar and mediastinal drainage lymph nodes, but no metastasis. Non-caseating epithelioid cell granulomas were also seen in the lung interstitium. Histopathological examination suggested that the squamous cell carcinoma originated from a solitary bronchial papilloma. A diagnosis of lung cancer complicated with sarcoidosis was difficult by clinical imaging alone, including FDG-PET/CT. This suggests the importance of bronchoscopic examination, if a clinical course of the disease appears to be different from the usual course. This was a rare case of squamous cell carcinoma which originated from a solitary bronchial papilloma.

Abstract
We report a resected case of thymoma with a solitary pulmonary metastasis. A 63-year-old woman had pointed out a solitary nodule in right lung field on chest X-ray. Computed tomography (CT) scan showed an anterior mediastinal tumor and a solitary lung nodule in the right lower lobe. Extended thymectomy and partial resection of right lung was performed. Pathological diagnosis showed an invasive thymoma (type B3) and a pulmonary metastasis. Post operative radiotherapy was administered and she is doing well 19 months following the resection. Thymoma with a solitary synclonous pulmonary metastasis is rare and is classified into Masaoka stage IVb. Generally, thymoma cases with distant metastasis are not indication for operation. But, if radical resection is possible, operation is recommended for good prognosis.

Abstract
A 48-year-old man underwent resection of a right upper lobe necrotic tumor and part of his chest wall. Lobe-selective bronchial blockade of bleeding from the right upper lobe was achieved by combining a left-side double-lumen endotracheal tube with a bronchial blocker placed at the right intermediate bronchus. The bleeding right upper lobe was isolated, and the other lobes were protected from blood contamination during the lobectomy procedure.
