Abstract
8p11 myeloproliferative syndrome is a rare hematological malignancy caused by the translocation of FGFR1. Patients present with a myeloproliferative neoplasm that frequently transforms into acute myeloid leukemia or T-lymphoblastic lymphoma/leukemia. Here, we report a molecular study of a patient with 8p11 myeloproliferative syndrome who developed acute B-lymphoblastic leukemia and then transformed to mixed-phenotype acute leukemia. A 67-year-old woman was diagnosed with a myeloproliferative neoplasm with t(6;8)(q27;p12) and was monitored for polycythemia vera. Four years later, she developed acute B-lymphoblastic leukemia with an additional chromosomal abnormality of - 7. Despite two induction regimens, she failed to achieve complete remission, and leukemia transformed into mixed-phenotype leukemia. Targeted sequencing of serial bone marrow samples identified the RUNX1 L144R mutation upon transformation to B-cell leukemia. After those two induction regimens, some RUNX1 mutation-positive leukemic cells obtained the JAK2 V617F mutation, which was associated with the emergence of myeloid markers, including myeloperoxidase.

Abstract
INTRODUCTION Exosomes are membrane-enclosed nanovesicles, which are increasingly being recognized as important cell communication components for their role in transmitting microRNAs (miRNAs). No previous study has addressed the exosomal miRNA profile in colorectal adenomas (CRAs) because the long-term culture of CRA is challenging. This study aimed to identify the miRNA signature in organoid exosomes derived from human CRA and colorectal cancer (CRC) samples. METHODS Organoid cultures were developed from resected colorectal tissues of patients with CRA or CRC undergoing surgery or endoscopic mucosal resection. Exosomes were prepared from the conditioned medium of the organoids. miRNAs were prepared from the exosomes and their source organoids. The miRNA expression profiles were compared using microarray analysis. The impact of alteration of miRNA expression on cell proliferation was examined using miRNA mimics or inhibitors in HT-29 human CRC cells. RESULTS We established 6 organoid lines from CRC and 8 organoid lines from CRA. Exosomal miRNA signatures were different between the organoids derived from CRA and CRC. Both exosomal and cellular miR-1246 expressions were upregulated in CRC-derived organoids compared to their expression in CRA-derived organoids. Alteration of miR-1246 expression by the miR-1246 mimic or inhibitor increased or decreased cell proliferation in HT-29 cells, respectively. CONCLUSIONS We report for the first time the miRNA profiles of exosomes in CRA- and CRC-derived organoids. The upregulation of miR-1246 might play a role in increased cell proliferation in the process of CRA-carcinoma transition.

Abstract
BACKGROUND Submucosal fibrosis observed during colorectal endoscopic submucosal dissection (ESD) is an important factor related to incomplete resection. Biopsy is generally accepted as having the potential to elicit submucosal fibrosis, but few reports have presented definitive proof. This study investigated the relation between submucosal fibrosis and colorectal ESD outcomes and assessed factors related to fibrosis, including pretreatment biopsy. METHODS After reviewing 369 records of colorectal ESD performed between January 2011 and December 2016, we assessed the relation between fibrosis and ESD outcomes. Multiple logistic regression analysis revealed fibrosis risk factors. RESULTS Severe fibrosis was related significantly to ESD outcomes such as the mean procedure time (p < 0.001), en bloc resection rate (p < 0.001), and R0 resection rate (p = 0.011). Multivariate analyses indicated residual lesions (ORs 175.4, p < 0.001), pretreatment biopsy (ORs 8.30, p = 0.002), nongranular-type laterally spreading tumors (LST-NG; ORs 5.86, p = 0.025), and invasive carcinoma (ORs 5.83, p = 0.03) as independent risk factors of severe fibrosis. In each macroscopic type, LST-NG was more strongly related to fibrosis induced by pretreatment than granular-type laterally spreading tumors with adjust ORs of 50.8 and 4.69. CONCLUSIONS Pretreatment biopsy causes submucosal fibrosis resulting in prolonged procedure times and incomplete resection. These findings suggest important benefits of avoiding biopsy before ESD.

Abstract
INTRODUCTION MicroRNAs (miRNAs) can serve as tumor biomarkers; however, their role in evaluating colorectal adenoma (CRA) is unclear. Recently, the organoid culture system enabled long-term expansion of human colon epithelium. This study aimed to examine the potential of exosomal miRNAs extracted from CRA organoids as biomarkers in the clinical liquid biopsy CRA test. METHODS We established organoid cultures from normal colon and CRA using resected specimens. Exosomes were isolated from the conditioned medium organoids. MiRNAs were isolated from the exosomes, and their expression profiles were compared using microarray analysis. To identify miRNA candidates for liquid biopsy, we prospectively compared changes in their expression in serum and exosomes before and after endoscopic resection in 26 patients with CRA. RESULTS Seven exosomal miRNAs were overexpressed in CRA organoids: miR-4323, miR-4284, miR-1268a, miR-1290, miR-6766-3p, miR-21-5p, and miR-1246. The expression levels of 4 exosomal miRNAs (miR-4323, miR-4284, miR-1290, and miR-1246) and 2 serum miRNAs (miR-1290 and miR-1246) were significantly lower in posttreatment sera. The combined expression of 4 exosomal miRNAs could identify both CRA and large-size (>12.6 cm2) CRA with respective areas under the curve of 0.698 (95% confidence interval [CI] = 0.536-0.823) and 0.834 (95% CI = 0.660-0.929). Combinations of 2-serum miRNA expression values could identify both CRA and large-size CRA with respective area under the curves of 0.691 (95% CI = 0.528-0.817) and 0.834 (95% CI = 0.628-0.938). DISCUSSION We found that exosomal miRNAs derived from the CRA organoid culture could be potential diagnostic biomarkers for CRA.

Abstract
Amyloidosis is classifiable as systemic, with amyloid deposition in organs throughout the body, or localized, involving only one organ. Amyloidosis localized in the intestinal tract is rare. This report describes three cases of localized AL amyloidosis in the intestinal tract and presents their clinical characteristics, endoscopic findings, and prognoses. All three cases were asymptomatic, and were found accidentally during endoscopy for closer examination after a positive fecal occult blood test. Endoscopic findings included patchy redness and meandering dilated vessels of the lesion. Using autofluorescence (AFI) endoscopy, the lesion of amyloid deposition was enhanced as bright green. We used fluorescence microscopy to observe unstained specimens obtained from an amyloid deposition site with excitation light. Autofluorescence was detected with the broad excitation wavelength at amyloid deposition lesion sites of the specimen. Results revealed that AL amyloid has autofluorescence that engenders its detection by AFI endoscopy as bright green. In none of the three cases was systemic amyloidosis or organ failure observed. The long-term course of all the cases was favorable.

Abstract
A 31-year-old man with Crohn's disease in remission after 6-year treatment with infliximab developed nasopharyngeal diffuse large B cell lymphoma. Infliximab was discontinued, and complete remission was achieved following chemotherapy with rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone. However, the patient subsequently experienced severely symptomatic Crohn's disease relapse. Therapy with adalimumab was initiated, and the patient attained remission. However, after 3 months, he suffered a recurrence of the lymphoma. Adalimumab was discontinued, and the patient received further chemotherapy (with rituximab, etoposide, cisplatin, methylprednisolone, and high-dose cytarabine) treatment and underwent allogeneic hematopoietic stem cell transplantation. Following the procedure, Crohn's disease and lymphoma have remained in complete remission for 5 years. There are limited reports on Crohn's disease remission after allogeneic hematopoietic stem cell transplantation. Therefore, we present this case report and a review of the existing literature on allogeneic stem cell transplantation for Crohn's disease.

Abstract
Tyrosine kinase inhibitors (TKIs) are standard therapies for chronic myeloid leukemia (CML) that can eradicate Ph-positive leukemic cells. However, disease control is not achievable in a minority of cases, most commonly due to evolution of TKI-resistant clones. There have also been rare cases of emergence of Ph-negative clones with other cytogenetic abnormalities, and, less commonly, development of Ph-negative acute myeloid leukemia (AML), whose molecular pathogenesis is largely unknown. Here we report molecular features of a patient with Ph + CML who developed Ph-negative AML after showing a major molecular response to dasatinib. A 55-year-old man was diagnosed with CML. He achieved a complete cytogenetic response three months after dasatinib therapy but developed AML with normal karyotype 1 year later. After receiving induction and consolidation chemotherapy for AML, the patient achieved complete remission with no evidence of CML under maintenance with bosutinib. Targeted sequencing of serial bone marrow samples identified mutations in IDH2 and NPM1 in the Ph-negative AML cells, which had not been detected in CML cells. These results suggest that Ph-negative AML in this patient originated from a preleukemic population, which might have expanded during or after the successful elimination of CML clones with TKI therapy.

Abstract
A 70-year-old woman experienced pain in both gastrocnemius muscles, numbness in the toes, and muscle weakness in both the legs that lasted for two months. After getting admitted to our hospital, the muscle weakness extended to both her arms, and nerve conduction studies revealed decreased nerve conduction velocity, which was more prominent in the elbow and the axilla than in the wrist. A magnetic resonance imaging revealed a tumor in the right femoral neck, which was histologically diagnosed as plasmacytoma. Laboratory findings revealed IgA lambda type M protein and an elevated VEGF level of 2,320 pg/ml; edema was present in both the legs. After a diagnosis of POEMS syndrome, lenalidomide and dexamethasone treatment were initiated simultaneously, along with irradiation. The treatment improved polyneuropathy, along with a decrease in the VEGF level. Increased vascular permeability due to elevated VEGF led to the development of neuropathy of POEMS syndrome, and treatment against proliferating monoclonal plasma cells is effective. In the present case, we believe that a prompt control of the plasmacytoma with novel therapeutic agents for myeloma with irradiation resulted in the improvement of the neurological symptoms.

Abstract
A 56-year-old man who sustained a right waist injury 1 month ago, reported to our department complaining of pain in the right waist and femur for 1 day. In a computed tomography examination, hematoma of the right iliopsoas muscle was revealed, and arterial embolization was immediately performed but was not effective. Laboratory findings showed hemoglobin levels as 5.4 g/dl, platelet of 20.2×104/µl, prothrombine time of 13.1 s, partial thromboplastin time (APTT) of 81.1 s, and a convex upward curve of the APTT cross-mixing test. The activity of the coagulation factor VIII was <1.0%, but its amount was 120%, and the level of factor VIII inhibitor was 130 Bethesda Unit/ml. Disseminated intravascular coagulation was not noted. Under the diagnosis of acquired hemophilia A, treatment with prednisolone and recombinant activated factor VII was initiated. However, APTT remained prolonged, and intubation and mechanical ventilation were required because of right hemothorax. After steroid pulse therapy and plasma exchange, APTT returned to its normal range, and the inhibitor disappeared. Thus, we finally succeeded in extubation. This case indicated that intensive care may be necessary in the early phase treatment for acquired hemophilia A.

Abstract
Shape perception can be achieved based on various cues such as luminance, color, texture, depth and motion. To investigate common neural mechanisms underlying shape perception cued by various visual attributes, we examined single-neuron activity in the monkey anterior superior temporal sulcus (STS) in response to shapes defined by luminance and motion cues during shape discrimination. We found cortical mapping with respect to selectivity for shapes as well as for direction of motion in the STS. About 90% of shape-selective neurons were located in the lower bank of STS (lSTS) assigned to the ventral pathway, while about 80% of direction-selective neurons existed in the upper bank of STS (uSTS) assigned to the dorsal pathway. The neurons showing selectivity for both shape and motion coexisted in lSTS as well as uSTS. This result indicates that integration or convergence of shape information and motion information can occur in both banks of STS. About 90% of STS neurons showing selectivity both for shapes defined by luminance cue and for shapes defined by motion cue were located in lSTS. They showed a highly similar shape preference between the different visual attributes, indicating cue-invariant shape selectivity. The cue-invariant shape-selectivity was modulated with target selection as well as with discrimination performance of monkeys. These results suggest that lSTS could be involved in cue-invariant shape discrimination, but not the uSTS.

Abstract
We report a 40-year-old woman diagnosed as having acute myeloid leukemia with CBFB-MYH11. Before and after stem cell transplantation in the phase of molecular remission of the marrow, CBFB-MYH11-positive cells were detected by RT-PCR analysis in skin lesions. The former was pathologically diagnosed as leukemic infiltration, while the latter was considered to be graft-versus-host disease. We can speculate that a low level of leukemic stem cells not detectable by RT-PCR analysis remained in the bone marrow, at least prior to transplantation. This case may suggest interesting biological features of inv(16)-type acute myeloid leukemia.

Abstract
We experienced two patients with mixed phenotype acute leukemia with t(9;22)(q34;q11.2); BCR-ABL1 according to the WHO classification 2008. The type of BCR/ABL1 was major in both patients, and the chimeric gene was also detected in neutrophils from peripheral blood by the fluorescence in situ hybridization technique. Patient 1 was a 59-year-old Japanese woman, and patient 2 a 45-year-old Japanese man. They had both developed leukemia suddenly. Their leukemic blasts expressed B cell and myeloid cell antigens, but concomitantly in patient 1 (biphenotypic) and separately in patient 2 (biclonal). Percentages of BCR-ABL1-positive neutrophils were 98% and 89%, respectively. Both patients received an imatinib (600 mg/day)-combined Hyper-CVAD regimen as induction therapy, followed by treatment with dasatinib (140 mg/day). MEC therapy was also applied between these two treatments in patient 2. At present, patient 1 has obtained complete molecular remission quantitatively and qualitatively, and patient 2 only quantitatively. Considering their acute onsets with no prior history of chronic myelocytic leukemia (CML), they were both diagnosed as having acute leukemia with Ph1, but not blastic crisis of CML. In this tyrosine kinase inhibitor era, it has become more difficult to differentiate these two types of Ph1-positive leukemia development.

Abstract
Over the past few years an increasing number of prospective controlled sarcoidosis treatment trials have been completed. Unfortunately, these studies utilize different endpoints making comparisons between studies difficult. At the recent World Association of Sarcoidosis and other Granulomatous disease (WASOG) meeting, a session was dedicated to the evaluation of clinical endpoints for various disease manifestations. These included pulmonary, pulmonary hypertension, fatigue, cutaneous, and a classification of clinical disease phenotypes. Based on the available literature and our current understanding of the disease, recommendations for clinical evaluation were proposed for each disease category. For example, it was recommended that pulmonary studies should include changes in the forced vital capacity. Additionally, it was recommended that all trials should incorporate measurement of quality of life.

Abstract
We report a 69-year-old male with CD3-positive peripheral T-cell lymphoma, not otherwise specified (PTCL-nos). Interestingly, tumor cells slightly expressed CD20 as well. Southern analyses of the tumor cells showed rearrangement for only the T cell receptor gene but not the immunoglobulin genes. This patient achieved partial remission with a treatment regimen of THP-COP excluding prednisolone, but died of pneumonia. Although CD20-positive PTCL is rare, a review of the reported cases suggests that CD20-positive PTCL has a poor prognosis and that bone marrow infiltration of tumor cells results in a poorer prognosis in CD20-positive PTCL than in usual PTCL. By accumulating cases of this rare entity of lymphoma, we need to clarify the biological nature of the tumor cells and usefulness of rituximab combined with standard chemotherapy.

Abstract
CD40 plays a critical role in adaptive immunity, and alveolar macrophages in patients with sarcoidosis express higher levels of CD40. This study investigated the association of rs1883832, a functional single-nucleotide polymorphism in the CD40 gene with susceptibility to sarcoidosis and phenotypes of sarcoidosis. Genotyping of rs1883832 in 175 Japanese patients with sarcoidosis and 150 age- and sex-matched controls revealed no significant difference between the genotypes of the patient and control groups (CC/CT/TT, 32.8/52.0/14.7% in the patients; 37.3/48.0/14.7% in the controls, P = 0.66; allele C, 59.1% in the patients, 61.3% in the controls, P = 0.57). T-cell and CD4+ cell counts in the bronchoalveolar lavage fluid were significantly higher in the TT genotype group than in the CC and CT genotype group.

Abstract
SETTING Kyoto, Japan. OBJECTIVE To determine predictors of 5-year mortality in pulmonary Mycobacterium avium-intracellulare complex (MAC) disease. DESIGN Retrospective study of 164 patients diagnosed with pulmonary MAC disease between 1999 and 2005 and followed for 5 years. RESULTS Overall 5-year mortality was 28.0%. Among 117 patients with microbiological outcomes, 54 were treated (treated MAC patients) and 24 were not treated and did not experience sputum culture conversion during follow-up (untreated chronic MAC patients); 39 patients were not treated and experienced sputum culture conversion. Five-year all-cause overall mortality among the 78 patients with definite MAC disease (including treated and untreated chronic MAC patients) was 25.6%. The mortality rate was 33.3% for untreated chronic MAC patients only vs. 22.2% for treated MAC patients (P = 0.30). After adjustment for clinical, microbiological and radiological confounders, independent factors for 5-year mortality were a high Charlson comorbidity index in cases with definite MAC disease (hazard ratio [HR] 1.76) and untreated chronic MAC (HR 3.08), and presence of cavitary lesions in cases with definite MAC disease (HR 1.82) and treated MAC patients (HR 3.91). CONCLUSION Patients with cavitary lesions require immediate treatment for sputum culture conversion and to improve their chances of survival.

Abstract
We previously tested a less toxic CAG regimen consisting of low-dose cytarabine, aclarubicin and granulocyte-colony stimulating factor for the treatment of patients with relapsed or refractory myeloid malignancies or elderly patients with untreated ones, obtaining a satisfactory complete remission rate of 62%. Gemtuzumab ozogamicin, an anti-CD33 monoclonal antibody conjugated to calicheamicin, has recently been approved as a single agent in Japan for the treatment of relapsed/refractory CD33-positive acute myelogenous leukemia (9 mg/m(2) on days1 and 15). Complete remission rate was reported as 30% in a phase 2 trial in Japan. In this study, effectiveness and safety of combining dose-attenuated gemtuzumab ozogamicin (3 mg/m(2) on day5) and original CAG regimen were assessed in nine patients with relapsed/refractory CD33-positive acute myelogenous leukemia and a median age of 70 years. Rate of complete remission with or without platelet recovery was 44% (4/9). The median duration of complete remission and overall survival were 5.5 and 16 months, respectively. Reversible myelosuppression and liver toxicity were the main adverse events, but no regimen-related death was recorded. Although only a small number of cases were included in this preliminary study, this CAG-GO regimen was found to be feasible and useful even in high-risk relapsed or refractory patients.

Abstract
BACKGROUND Effects of long-term treatment with inhaled corticosteroids (ICSs) on airway-wall thickness in patients with asthma remain unknown. OBJECTIVES To determine whether airway-wall thickness consistently decreases after long-term ICS treatment, and to analyze factors contributing to long-term airway-wall changes in asthmatics. METHODS A retrospective analysis of long-term changes in airway-wall thickness using computed tomography was performed in 14 patients with asthma. Wall area corrected by body surface area (WA/BSA) was examined at baseline, 12 weeks after the commencement of ICSs (second measurement), and at least 2 years (mean +/- SEM. 4.2 +/- 0.5) after the second measurement (third measurement). Mean +/- SEM changes in WA/BSA from the second to the third measurements were analyzed. RESULTS The mean change in WA/BSA was not significant between the second and the third measurements (-0.27 +/- 0.59 mm2/m2/y). Overall, the changes were significantly associated with disease duration but not with other clinical indices. When the 14 patients were divided into 2 groups using a cutoff value of 0.32 mm2/m2/y for the mean change in WA/BSA, for the 5 patients whose WA/BSA exceeded this cutoff, daily ICS doses were not reduced and both forced expiratory volume in the first second (FEV1) and forced vital capacity decreased significantly. For the remaining 9 patients, daily ICS doses were reduced and long-term FEV1 values did not change. CONCLUSIONS Despite long-term treatment with ICSs, airway-wall thickness did not consistently decrease. One possible mechanism underlying poor response to long-term treatment may be long-standing asthma.

Abstract
Octacalcium phosphate (OCP) and porcine atelocollagen sponge composites (OCP/Col) markedly enhanced bone regeneration in a rat cranial defect model. To assess clinical application, the authors examined whether OCP/Col would enhance bone regeneration in an alveolar cleft model in an adult dog, which was assumed to reflect patients with alveolar cleft. Disks of OCP/Col or collagen were implanted into the defect and bone regeneration by OCP/Col or collagen was investigated 4 months after implantation. Macroscopically, the OCP/Col-treated alveolus was obviously augmented and occupied by radio-opacity, and the border between the original bone and the defect was indistinguishable. Histological analysis revealed it was filled and bridged with newly formed bone; a small quantity of the remaining implanted OCP was observed. X-ray diffraction patterns of the area of implanted OCP/Col indicated no difference from those of dog bone. In the collagen-treated alveolus, the hollowed alveolus was mainly filled with fibrous connective tissue, and a small amount of new bone was observed at the defect margin. These results suggest that bone was obviously repaired when OCP/Col was implanted into the alveolar cleft model in a dog, and OCP/Col would be a significant bone regenerative material to substitute for autogeneous bone.

Abstract
BACKGROUND CD24 proteins are expressed on several inflammatory cells, and play an important role for the T-cell activation. OBJECTIVES The aim of this study is to investigate the relationship of a CD24 gene polymorphism to disease susceptibility or clinical findings including bronchoalveolar lavage (BAL) cell profiles in Japanese sarcoidosis patients. METHODS A previously reported functional single nucleotide polymorphism (SNP) of CD24 gene exon 2 was examined in 186 Japanese sarcoidosis patients and 146 sex and age-matched healthy controls using restriction fragment length polymorphism method. The distribution of genotypes was compared between the two groups. The association between genotypes or alleles and clinical features or BAL cell profiles was also examined. RESULTS There were no significant differences in the distribution of genotypes or allele frequencies between sarcoidosis and controls. There were also no significant differences in clinical features or BAL cell profiles among patients with different genotypes of CD24. CONCLUSIONS There was no relationship between a CD24 exon 2 SNP and disease susceptibility or clinical findings in Japanese sarcoidosis patients.

Abstract
BACKGROUND Cardiac involvement and pulmonary hypertension (PH) are life-threatening complications in sarcoidosis. OBJECTIVE This study aimed to investigate the utility of plasma NT-proBNP in the assessment of these conditions in sarcoidosis patients. STUDY DESIGN AND METHODS A prospective, observational study was performed on 150 consecutive Japanese sarcoidosis patients. Doppler echocardiography was performed in all subjects, and those who were successfully evaluated for PH status were included in the analysis. Cardiac sarcoidosis was diagnosed based on Japanese guidelines, and PH was defined as estimated systolic pulmonary artery pressure (sPAP) > or = 35 mmHg. The diagnostic accuracy of NT-proBNP according to the presence of cardiac sarcoidosis and PH was assessed based on receiver-operator characteristic (ROC) curves. RESULTS 130 subjects were successfully evaluated for PH status. Of these, 29 met the diagnostic criteria of cardiac sarcoidosis, and 21 were diagnosed with PH. Plasma NT-proBNP levels were significantly higher in patients with cardiac sarcoidosis (p < 0.0001). Stepwise regression analysis showed that presence of cardiac sarcoidosis, decreased ejection fraction and increased sPAP were all independently associated with higher plasma NT-proBNP levels. Plasma NT-proBNP showed good accuracy in identifying patients with cardiac sarcoidosis (area under the ROC curve; AURC = 0.913). However, even when patients with cardiac sarcoidosis were excluded, plasma NT-proBNP levels could not be used reliably to identify patients with PH (AURC = 0.681). CONCLUSION In patients with sarcoidosis, plasma NT-proBNP levels are a useful biomarker to identify cardiac involvement, but not to identify PH.

Abstract
BACKGROUND The profile of intestinal organic acids in irritable bowel syndrome (IBS) and its correlation with gastrointestinal (GI) symptoms are not clear. We hypothesized in this study that altered GI microbiota contribute to IBS symptoms through increased levels of organic acids. METHODS Subjects were 26 IBS patients and 26 age- and sex-matched controls. Fecal samples were collected for microbiota analysis using quantitative real-time polymerase chain reaction and culture methods, and the determination of organic acid levels using high-performance liquid chromatography. Abdominal gas was quantified by image analyses of abdominal X-ray films. Subjects completed a questionnaire for GI symptoms, quality of life (QOL) and negative emotion. KEY RESULTS Irritable bowel syndrome patients showed significantly higher counts of Veillonella (P = 0.046) and Lactobacillus (P = 0.031) than controls. They also expressed significantly higher levels of acetic acid (P = 0.049), propionic acid (P = 0.025) and total organic acids (P = 0.014) than controls. The quantity of bowel gas was not significantly different between controls and IBS patients. Finally, IBS patients with high acetic acid or propionic acid levels presented with significantly worse GI symptoms, QOL and negative emotions than those with low acetic acid or propionic acid levels or controls. CONCLUSIONS & INFERENCES These results support the hypothesis that both fecal microbiota and organic acids are altered in IBS patients. A combination of Veillonella and Lactobacillus is known to produce acetic and propionic acid. High levels of acetic and propionic acid may associate with abdominal symptoms, impaired QOL and negative emotions in IBS.

Abstract
The authors report here a case of in situ follicular lymphoma (FL) associated with progressive transformation of the germinal center (PTGC). A 39-year-old Japanese male developed a mass in the right cervical region. Biopsy of the enlarged lymph node led to a diagnosis of PTGC. Then, 5 years later, the lymphadenopathy recurred. The second biopsy specimens contained numerous germinal centers, including PTGC. Although most follicles were cytologically reactive, a few GCs appeared to be somewhat monotonous, composed predominantly of centrocytes and lacking mitotic figures and tangible body macrophages. Immunohistochemical studies demonstrated that these atypical GCs were CD10+, CD20+, and bcl-2+, with λ-light-chain restriction. A previous report emphasized the differential diagnostic problem between PTGC and the floral variant of FL. However, the present case indicated that in situ FL should be added to the list of differential diagnoses for PTGC.

Abstract
BACKGROUND Chronic beryllium disease (CBD) is a rare disease, and there are no previous reports that have followed CBD patients over several decades. Thus, the long-term complications and prognosis of this illness still remain unclear. OBJECTIVE The aim of this study was to investigate long-term complications and prognosis of CBD patients. STUDY DESIGN AND METHODS This was a retrospective study based on the medical records of all CBD patients diagnosed at Kyoto University Hospital between the period 1973 to the present day. Ultimately, ten patients whose diagnoses had been made during the period 1973 to 1977 were included. Long-term physiological and radiological change, complications and prognosis of these patients were investigated. RESULTS Three patients completely remitted, and one died of cor-pulmonale. Among the remaining six patients, four have been followed up for more than thirty years in our institute. The majority developed mixed patterns of lung function impairment, cavity lesions of the lung, pneumothorax, and respiratory infections. CONCLUSIONS Long-term prognosis of CBD was poor with several complications due to chronic parenchymal and airway lesions.

Abstract
OBJECTIVES The association between HLA class II alleles and susceptibility to sarcoidosis is well documented. Further, the HLA-DRB1 15 and DQB1 0602 haplotype has been considered as a marker for both chronic and severe disease. Splenomegaly has been proposed as a marker for severity and activity in sarcoidosis, although its functional mechanism is unknown. In other diseases, HLA class II alleles can be markers for splenomegaly. We therefore set out to test the hypothesis that the primary DRB1 15-DQB1 0602 link in sarcoidosis would be to splenomegaly. DESIGN AND SUBJECTS We performed abdominal ultrasonography to evaluate the prevalence and extent of splenomegaly and genotyped for HLA-DRB1 and DQB1 using allele or allele group specific primers in polymerase-chain-reaction on 138 Japanese sarcoidosis patients as case comparison study. Furthermore, we explored their relationship with other clinically important indices, e.g. chest radiograph stage, serum angiotensin-converting enzyme (ACE) concentration and duration of disease. RESULTS Splenomegaly was detected in 37 (26.8%) sarcoidosis patients. DQB1 0602 showed associations with splenomegaly (P < 0.0001) and longer disease duration (P = 0.007). In addition, higher chest radiograph staging was associated with both DQB1 0602 (P = 0.02) and splenomegaly (P = 0.003). The presence of splenomegaly was associated with higher serum ACE concentration (P < 0.0001). CONCLUSION We conclude that in the Japanese population the primary association of HLA class II DQB1 0602 is with splenomegaly. This allele is also a marker for chronicity and lung disease severity. On the other hand, the presence of splenomegaly is a marker for severity and activity. Further studies are needed to explore the relationship between splenomegaly and sarcoidosis in other ethnic groups and its association with HLA-DQB1 0602.

Abstract
A 55-year-old man with advanced myelodysplastic syndrome was hospitalized prior to undergoing an allogeneic bone marrow transplantation. Immediately before hospitalization, he had suffered from phlegmon in both lower extremities and right forearm as well as genital and oral ulcers. After admission, he developed an esophageal ulcer and was thus diagnosed as having intestinal tract-type Behçet disease. HLA-B51 was not present. Within a month, he died of pulmonary hemorrhage associated with pneumonia, possibly because of a low platelet count, and vasculoendothelial damage related to Behçet disease. This is a rare case of myelodysplastic syndrome that developed Behçet disease with a severe esophageal ulcer.

Abstract
We report results from a study of events with a double-Pomeron exchange topology produced in p p collisions at sqrt[s]=1800 GeV. The events are characterized by a leading antiproton and a large rapidity gap on the outgoing proton side. We find that the differential production cross section agrees in shape with predictions based on Regge theory and factorization, and that the ratio of double-Pomeron exchange to single diffractive production rates is relatively unsuppressed as compared to the O(10) suppression factor previously measured in single diffractive production.

Abstract
Central diabetes insipidus (DI) is a rare but recognized complication of myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML) that is caused by leukemic infiltration to the hypothalamo-neurohypophyseal system. In rare patients in whom a wide region of the hypothalamus is involved, central DI results in hypodipsic hypernatremia and dehydration. Typical DI symptoms such as polydipsia, polyuria, and marked thirst are concealed in these cases, because the hypothalamic "thirst center" cannot send thirst stimuli to the cerebral cortex. Herein we describe a patient with MDS developing into AML, who presented with hypodipsic hypernatremia and dehydration. A diagnosis of central DI was made on the ground of a low level of serum anti-diuretic hormone (ADH) despite high serum osmolality. A magnetic resonance imaging study revealed attenuation of a physiological "bright spot" of the neurohypophysis. An induction course chemotherapy including regular-dose cytarabine and daunorubicin produced a rapid improvement of hypernatremia. The bone marrow aspirate after two courses of chemotherapy showed complete remission. At that point, ADH release and the "bright spot" were recovered. In order to correctly diagnose central DI in association with hematological malignancies, we should not overlook this atypical type of DI.

Abstract
A 17-year-old female was admitted to our hospital because of pyrexia and thrombocytopenia in May 2002. Laboratory examination showed a platelet count of 50,000/microliter with an increased level of fibrinogen degradation product, leading to a diagnosis of disseminated intravascular coagulation (DIC). Gabexate mesilate was intravenously administrated without any effects. Several days later, erythema, joint pain and neck lymphadenopathy developed sequentially. The patient was diagnosed as having adult-onset Still disease (AOSD) complicated with DIC. Moreover, serum inflammatory cytokine levels had increased and activated macrophages were observed in the bone marrow, suggesting the presence of macrophage activation syndrome. After additional treatments with dalteparin and aspirin, the clinical symptoms and laboratory findings associated with AOSD and DIC disappeared. Although this was a severe case of AOSD associated with preceding DIC, the AOSD symptoms resolved in this patient with the treatment of the DIC and with aspirin only without any relapse.

Abstract
We report on a search for direct Kaluza-Klein graviton production in a data sample of 84 pb(-1) of ppmacr; collisions at sqrt[s]=1.8 TeV, recorded by the Collider Detector at Fermilab. We investigate the final state of large missing transverse energy and one or two high energy jets. We compare the data with the predictions from a (3+1+n)-dimensional Kaluza-Klein scenario in which gravity becomes strong at the TeV scale. At 95% confidence level (C.L.) for n=2, 4, and 6 we exclude an effective Planck scale below 1.0, 0.77, and 0.71 TeV, respectively.

Abstract
We present the results of a search for pair production of scalar top quarks (t(1)) in an R-parity violating supersymmetry scenario in 106 pb(-1) of pp collisions at square root of s=1.8 TeV collected by the Collider Detector at Fermilab. In this mode each t(1) decays into a tau lepton and a b quark. We search for events with two tau's, one decaying leptonically (e or mu) and one decaying hadronically, and two jets. No candidate events pass our final selection criteria. We set a 95% confidence level lower limit on the t(1) mass at 122 GeV/c(2) for Br(t(1)-->tau b)=1.

Abstract
A 26-year-old woman was diagnosed as having autoimmune hemolytic anemia in September 2002. Her eosinophil count was already high (2,190/microliter) at that time. She received prednisolone therapy with a good response and was released from the treatment in April 2003. Eosinophil numbers were within the normal range under the prednisolone administration. However, they began to increase after its completion. No underlying causes for the eosinophilia were evident. When the eosinophil count reached 5,474/microliter, the patient developed massive pleural effusion as well as palpebral swelling and myalgia, leading to a diagnosis of hypereosinophilic syndrome. Re-administration of prednisolone resulted in the disappearance of these symptoms and eosinophilia. Her eosinophils seemed to have reactivated after cessation of the prednisolone therapy and infiltrated into her organs.

Abstract
We report on a search for a high mass, narrow width particle that decays directly to emu, etau, or microtau. We use approximately 110 pb(-1) of data collected with the Collider Detector at Fermilab from 1992 to 1995. No evidence of lepton flavor violating decays is found. Limits are set on the production and decay of sneutrinos with R-parity violating interactions.

Abstract
Efficient Agrobacterium -mediated transformation of Antirrhinum majus L. was achieved via indirect shoot organogenesis from hypocotyl explants of seedlings. Stable transformants were obtained by inoculating explants with A. tumefaciens strain GV2260 harboring the binary vector pBIGFP121, which contains the neomycin phosphotransferase gene ( NPT II) as a selectable marker and the gene for the Green Fluorescent Protein ( GFP) as a visual marker. Putative transformants were identified by selection for kanamycin resistance and by examining the shoots using fluorescence microscopy. PCR and Southern analyses confirmed integration of the GFP gene into the genomes of the transformants. The transformants had a morphologically normal phenotype. The transgene was shown to be inherited in a Mendelian manner. This improved method requires only a small number of seeds for explant preparation, and three changes of medium; the overall transformation efficiency achieved, based on the recovery of transformed plants after 4-5 months of culture, reached 8-9%. This success rate makes the protocol very useful for producing transgenic A. majus plants.

Abstract
We report a measurement of the fraction of events with a large pseudorapidity gap deltaeta within the pseudorapidity region available to the proton dissociation products X in p+p-->p+X. For a final state p of fractional momentum loss xi(p) and 4-momentum transfer squared t(p) within 0.06<xi(p)<0.09 and |t(p)|<1.0 [0.2] GeV2 at sqrt[s]=1800 [630] GeV, the fraction of events with deltaeta>3 is found to be 0.246+/-0.001 (stat)+/-0.042 (syst) [0.184+/-0.001 (stat)+/-0.043 (syst)]. Our results are compared with gap fractions measured in minimum bias pp collisions and with theoretical expectations.

Abstract
We have searched for pair production of the supersymmetric partner of the top quark (stop) in 107 pb(-1) of pp collisions at square root of s=1.8 TeV collected by the Collider Detector at Fermilab (CDF). Each stop is assumed to decay into a lepton, bottom quark, and supersymmetric neutrino. Such a scenario would give rise to events with two leptons, two hadronic jets, and a substantial imbalance of transverse energy. No evidence of such a stop signal has been found. We exclude stop masses in the region (80</=m(t)</=135 GeV/c(2)) in the mass plane of stop versus sneutrino.

Abstract
We present a search for associated production of the Upsilon(1S) and a vector boson in 83 pb(-1) of ppmacr; collisions at sqrt[s]=1.8 TeV collected by the CDF experiment in 1994-1995. We find no evidence of the searched signal in the data, and set upper limits to the production cross sections.

Abstract
SUMMARY The authors reviewed 531 patients with cerebral aneurysms treated with Guglielmi detachable coils (GDCs) over 5 years to clarify both the advantages and disadvantages of embolization based on the evidence of complications by aneurysm profile. There were 52 technical complications, 25 of which resulted in unfavorable patient outcomes. Intraoperative rupture, the most serious complication exacerbating the patient's condition, occurred in 19 patients, 4 of whom expired. All of these aneurysms were very small and were mostly located in the AcomA and PICA portions. Thirteen patients encountered thromboembolic complications, 6 of whom were elderly with acute ruptured aneurysms at MCA and the tip of BA. For large or giant aneurysms manifesting the mass effect, particularly those in the ICA-C2 portion compressing the optic nerve, the saccular packing did little to ameliorate the symptoms, and subsequent surgical or endovascular trapping was needed. Therefore, saccular embolization of endovascularly difficult, very small AcomA aneurysms and large C2 aneurysm with visual symptoms should be used sparingly based on a risk-benefit assessment.

Abstract
We report a search for the production of long-lived charged massive particles in a data sample of 90 pb(-1) of square root[s]=1.8 TeV pp collisions recorded by the Collider Detector at Fermilab. The search uses the muonlike penetration and anomalously high ionization energy loss signature expected for such a particle to discriminate it from backgrounds. The data are found to agree with background expectations, and cross section limits of O(1) pb are derived using two reference models, a stable quark and a stable scalar lepton.
