Abstract
Vaccination with a coronavirus disease-2019 (COVID-19) vaccine is an effective public health measure for reducing the risk of infection and severe complications from COVID-19. However, serious hematological complications after COVID-19 vaccination have been reported. Here, we report a case of new-onset hypomegakaryocytic thrombocytopenia (HMT) with the potential for progression to aplastic anemia (AA) that developed in a 46-year-old man 4 days after the fourth mRNA COVID-19 vaccination. Platelet count rapidly decreased after vaccination and white blood cell count declined subsequently. Bone marrow examination immediately after disease onset showed severely hypocellular marrow (cellularity of almost 0%) in the absence of fibrosis, findings that were consistent with AA. Since the severity of pancytopenia did not meet the diagnostic criteria for AA, the patient was diagnosed with HMT that could progress to AA. Treatment with eltrombopag and cyclosporine was started immediately after diagnosis and cytopenia improved. Although it is difficult to determine whether the post-vaccination cytopenia was vaccine induced or accidental because the association was chronological, vaccination with an mRNA-based COVID-19 vaccine may be associated with development of HMT/AA. Therefore, physicians should be aware of this rare, but serious adverse event and promptly provide appropriate treatment.

Abstract
BACKGROUND Unlike the already established effect of Helicobacter pylori (H. pylori) eradication on gastric mucosa-associated lymphoid tissue (MALT) lymphoma, its therapeutic effect on primary gastric diffuse large B-cell lymphoma (DLBCL) is still unclear. AIM To clarify the efficacy of H. pylori eradication treatment for primary gastric DLBCL. METHODS We reported on 3 new cases, and added them to 3 previously reported cases. We analyzed the usefulness of H. pylori eradication treatment for gastric DLBCL for a total of 6 cases at our center. RESULTS Of the 6 patients (27-90 years old, 3 males and 3 females), all 3 patients with single lesions (one transformed from MALT lymphoma) achieved complete remission (CR) after H. pylori eradication. Regarding the 2 newly reported cases, CR was maintained for more than 6 years with eradication treatment alone. In contrast, none of the 3 patients with 2 lesions achieved CR. In 1 newly reported case, endoscopic CR was achieved in one lesion, while stable disease was obtained in the other lesion. Two patients with progressive disease responded to standard chemotherapy ± radiation and remained in CR for more than 6 years. CONCLUSION We believe it is worthwhile to attempt H. pylori eradication for elderly patients with primary gastric DLBCL in a single lesion with a small tumor burden.

Abstract
The JSH Practical Guidelines for Hematological Malignancies, 2018 expanded edition, newly adopted brentuximab vedotin, doxorubicin, vinblastine, dacarbazine(A+AVD)protocol as a standard treatment for advanced-stage classical Hodgkin lymphoma(CHL). Therefore, this retrospective analysis compared 15 patients who received A+AVD therapy with 21 patients who received doxorubicin, bleomycin, vinblastine, dacarbazine(ABVD)therapy. All patients were newly diagnosed with CHL and received induction therapy between April 2015 and June 2022 in our hospital. All except 1 patient of the A+AVD group had advanced-stage CHL. The median age was 63(23-85)years. The estimated 2-year overall survival of the A+AVD group was better than that of the ABVD group which included 6 patients with clinical stage Ⅲ or higher CHL (100% vs 66.7%, p=0.047). In contrast, there was no significant difference in the complete response rate(53.8% vs 100%, p=0.109)between the 2 groups. The overall response rate after first-line treatment(69.2% vs 100%, p=0.255), and the estimated 2-year progression-free survival(70.1% vs 66.7%, p=0.321)between the A+AVD and the ABVD groups were similar.

Abstract
BACKGROUND We have reported that seroconversion rates after the second dose of mRNA-based COVID-19 vaccines for myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML) were 100% and 95% respectively, with no significant difference from healthy controls (HCs).However, there are very limited data for the response to a third vaccine dose in those patients. AIMS In this complementary study, we investigated the booster effect of a third mRNA-based COVID-19 vaccine dose in patients with myeloid malignancies. MATERIALS & METHODS A total 58 patients including 20 patients with MDS and 38 patients with AML were enrolled. Anti-SARS-CoV-2S immunoassays were performed at 3, 6, and 9 months after the second vaccine dose. RESULTS Seventy-five percent of the MDS patients and 37% of the AML patients were receiving active treatment at the time of the third vaccination. Both the initial and third vaccine response in AML patients were comparable to those in HCs. In MDS patients, although the initial vaccine immunogenicity was inferior to that in HCs and AML patients, the third vaccine improved the response to a level not inferior to those in HCs and AML patients. Of note, the third vaccine resulted in a significant increase of antibodies in actively treated MDS patients who had shown a response inferior to that in untreated patients after two doses of vaccination. DISCUSSION In patients with myeloid malignancies, the third vaccine dose showed a booster effect, and disease- and therapy-related factors associated with the booster response have been identified. CONCLUSION The third dose of an mRNA-based COVID-19 vaccine showed a booster effect in patients with myeloid malignancies. Such a good booster response has not been reported in other haematological malignancies.

Abstract
Serologic responses of COVID-19 vaccine are impaired in patients with B-cell lymphoma, especially those who had recently been treated with anti-CD20 monoclonal antibodies. However, it is still unclear whether those patients develop an immune response following vaccination. We investigated the efficacy of vaccination against SARS-CoV-2 in 171 patients with B-cell non-Hodgkin lymphoma (B-NHL) who received two doses of an mRNA-based COVID-19 vaccine and we compared the efficacy of vaccination to that in 166 healthy controls. Antibody titers were measured 3 months after administration of the second vaccine dose. Patients with B-NHL showed a significantly lower seroconversion rate and a lower median antibody titer than those in healthy controls. The antibody titers showed correlations with the period from the last anti-CD20 antibody treatment to vaccination, the period from the last bendamustine treatment to vaccination and serum IgM level. The serologic response rates and median antibody titers were significantly different between diffuse large B-cell lymphoma (DLBCL) patients in whom anti-CD20 antibody treatment was completed within 9 months before vaccination and follicular lymphoma (FL) patients in whom anti-CD20 antibody treatment was completed within 15 months before vaccination. Moreover, the serologic response rates and median antibody titers were significantly different among FL patients in whom bendamustine treatment was completed within 33 months before vaccination. We demonstrated that B-NHL patients who were recently treated with anti-CD20 antibodies and bendamustine had a diminished humoral response to COVID-19 vaccination. UMIN 000,045,267.

Abstract
Data for COVID-19 vaccine response in patients with immune thrombocytopenia (ITP) are very limited. In a study of 28 patients with ITP, anti-severe acute respiratory syndrome coronavirus 2 spike antibody titres were measured after vaccination. The seroconversion rate for ITP patients was 91.3%, comparable to that in healthy controls (HCs). However, the antibody titre in ITP patients was significantly lower than that in HCs and declined with ageing. Furthermore, the antibody titre in ITP patients who received a minimum prednisolone dose of at least 5 mg/day at any time-point at or after initial vaccination was lower than that in other patients.

Abstract
Abstract
Background
Tafamidis is a stabilizer of transthyretin, specifically designed to decrease or prevent amyloidogenesis, and improves prognosis in patients with transthyretin amyloid cardiomyopathy (ATTR-CM). However, clinical coarse, selection of appropriate patients and monitoring therapeutic effect of tafamidis remained unclear.
Purpose
The aim of this study was to clarify the patients' characteristics, clinical coarse, and clinical outcomes of tafamidis in patients with ATTR-CM and to evaluate prognostic factors and changes in clinical data over time.
Methods
We evaluated consecutive 180 patients with ATTR-CM considering tafamids treatment. A total of 107 patients had tafamidis treatment (tafamidis treatment group) and 65 patients did not treat with tafamidis (treatment naïve group). The remaining 8 patients were preclinical. Clinical data were obtained at the consideration of tafamidis treatment. We divided the following the cut-off values of high-sensitivity cardiac troponin T (hs-cTnT); >0.05 ng/mL, B-type natriuretic peptide (BNP); >250 pg/ml, and estimated glomerular filtration rate (eGFR); <45 mL/min/1.73 m2 and calculated the score by adding 1 point if increased or decreased by more than the cut-off value. We divided patients into a low score group (0–1 point) and high score group (2–3 points).
Results
All of study patients in the tafamidis treatment group were wild-type ATTR-CM. Compared to tafamidis treatment group, tafamidis naïve group were significantly older (75.6±5.3 vs. 82.8±4.6 years; p<0.01), female dominant (8% vs. 28%; p<0.01), increased BNP levels (median 209 vs 306 pg/ml; p<0.01), and lower haemoglobin levels (14.1±1.8 vs. 12.4±1.8 g/dl; p<0.01). Tafamidis treatment group was significantly favourable clinical outcomes competed to treatment naïve group (p<0.05; log rank test). According to multivariate logistic regression analysis, prior heart failure hospitalization (hazard ratio [HR]: 5.93, 95% confidence interval [CI]: 1.25–28.03, p=0.03) and high score group (HR: 1.56, 95% CI: 0.37–7.25; <0.01) were the significant poor prognostic factors in tafamids treatment group. Among tafamidis treatment group, Hs-cTnT levels were significantly decreased after 12 months tafamidis treatment (0.055 [0.037–0.082] vs. 0.044 [0.033–0.077]; p<0.01) instead of no significant differences in BNP and significant decline of eGFR levels. There were no significant changes over time in the echocardiographic parameters after 12 months, and native T1 and extracellular volume fraction obtained by cardiac magnetic resonance in a limited number of patients.
Conclusion
The prognosis of ATTR-CM patients treated with tafamidis was favorable compared to tafamidis naïve group. Patient stratification combined with biomarkers predicted favorable prognosis in patients with tafamidis treatment. Hs-cTnT may be a useful maker for evaluating the therapeutic effect by tafamidis.

Abstract
Abstract
Background
Transthyretin amyloid cardiomyopathy (ATTR-CM) is a progressive and infiltrative disease caused by the deposition of insoluble transthyretin (TTR) amyloid fibrils in the myocardium, which leads to cardiomyopathy characterized by increased ventricular wall thickness and diastolic dysfunction. TTR amyloid fibrils are performed by dissociation of the tetrameric TTR into monomers and misfolding and misassemble into insoluble fibrils. Tafamidis stabilizes the tetramers and inhibits the TTR monomerization, leads to inhibit the formation and deposition of TTR fibril. Clinical trials suggested tafamidis could improve prognosis by slowing the progression of amyloidosis. Evaluation of serial measurement echocardiographic findings by tafamidis treatment is important, but these data has not been fully revealed.
Purpose
The aim of study was to evaluate the change of echocardiographic parameter in patients with ATTR-CM received tafamidis for 12 months. Especially in strain echocardiogram, global longitudinal strain (GLS) has reported to be associated with prognosis, and apical sparing pattern, which longitudinal strain (LS) in the basal and middle segments is more severely impaired than the apical segments, is specific finding in ATTR-CM.
Method
Echocardiographic findings before and 12 months were compared in 68 patients with ATTR-CM who started a new prescription of tafamidis and 18 tafamidis naïve patients with ATTR-CM patients who underwent echocardiography annually prior to the approval of tafamidis.
Result
Among tafamidis treatment group, echocardiographic parameters were not significant changes before and after 12 months tafamidis treatment [left ventricular ejection fraction (LVEF): 49.6±10.6% vs. LVEF: 49.9±10.7% (p=0.767), interventricular septum diameter (IVSd):16.0±2.3mm vs 15.7±2.1mm (p=0.241), left ventricular posterior wall diameter (LVPWd):16.1±2.5mm vs 16.1±2.5mm (p=0.964), GLS: −8.4±2.7% vs −8.2±2.8% (p=0.419), LS at base: −4.6±2.6% vs −4.2±2.4% (p=0.291), LS at middle: −6.9±3.6% vs −6.9±2.8% (p=0.922), LS at apical:-12.7±4.2% vs −12.4±4.4% (p=0.615). Among tafamidis naïve group, these parameters remained almost unchanged in 12 months as well, except for GLS and LS at apical. LS at apical showed a significant impairment. [LVEF: 53.8±9.2% vs 51.7±9.3% (p=0.244), IVSd: 15.5±2.3mm vs 16.0±1.8mm (p=0.321), LVPWd: 15.4±2.3mm vs 15.9±2.3mm (p=0.267), GLS: −10.4±2.4% vs −9.0±2.9% (p=0.065), LS at base: −5.0±2.7% vs −5.1±2.9% (p=0.865), LS at middle: −8.9±3.1% vs −8.5±3.5% (p=0.565), LS at apical: −15.4±4.0% vs −12.6±4.4% (p=0.02); Table 1]
Conclusion
We evaluated changes in echocardiographic findings with tafamidis treatment for 12 months. The echocardiographic parameters did not change over the course of 12 months, but the decrease in LS at apex observed in the tafamidis naïve group.Segmental LS could reflect a slight progression of cardiac amyloidosis and the short-term effects of tafamidis.

Abstract
BACKGROUND Duodenal-type follicular lymphoma (D-FL) has been recognized as a rare entity that accounts for approximately 4% of primary gastrointestinal lymphomas. D-FL follows an indolent clinical course compared with common nodal FL and is generally considered to have a better prognosis. Therefore, the “watch and wait” approach is frequently adopted as the treatment method. Alternatively, there is an option to actively intervene in D-FL. However, the long-term outcomes of such cases are poorly understood.
AIM To clarify the clinical outcomes after long-term follow-up in cases of D-FL with treatment intervention.
METHODS We retrospectively analyzed patients who met the following criteria: the lesion was confirmed by endoscopy, the diagnosis of D-FL was confirmed histopathologically, and the patient was followed-up for more than 10 years after the intervention at our center.
RESULTS We identified 5 cases of D-FL. Two patients showed a small amount of bone marrow involvement (Stage IV). Rituximab was used as a treatment for remission in all 5 patients. It was also used in combination with chemotherapy in 2 Stage IV patients as well as for maintenance treatment. Radiation therapy was performed in 2 cases, which was followed by complete remission (CR). Eventually, all 5 patients achieved CR and survived for more than 10 years. However, 3 patients experienced recurrence. One patient achieved a second CR by retreatment, and in another case, the lesion showed spontaneous disappearance. The remaining patient had systemic widespread recurrence 13 years after the first CR. Biopsy results suggested that the FL lesions were transformed into diffuse large B-cell lymphoma. The patient died 4 years later despite receiving various chemotherapies.
CONCLUSION In this study, the treatment for patients of D-FL in Stage IV was successful. In the future, criteria for how to treat “advanced” D-FL should be established based on additional cases. This study of patients with D-FL indicates that whole-body follow-up examinations should continue for a long time due to a fatal recurrence 13 years after reaching CR.

Abstract
Colorectal follicular lymphoma (FL) is rare. In addition, it is even rarer that colon cancer develops synchronously with colorectal lymphoma. The present study reports a case of sigmoid colon cancer that developed 6 months after endoscopic resection of rectal FL. A 71-year-old man with a history of developing mucosa-associated lymphoid tissue lymphoma in his stomach at age 48, right neck region at age 59 (the latter later modified as FL) and lung adenocarcinoma at age 60 now suffers from rectal FL. Endoscopic submucosal dissection (ESD) was performed at our hospital (Aiiku Hospital), and 6 months after the treatment, sigmoid colon cancer was confirmed by colonoscopy for the follow-up study. The patient was successfully curatively resected by ESD plus local resection and has survived without a recurrence for >3 years with no treatment. It was speculated that in the present case, cancer-related genes were changed as a carcinogenic mechanism due to decreased immune function associated with the onset of lymphoma.

Abstract
Data on the response to the COVID‐19 vaccine in patients with myeloid malignancy, who are at severe risk in case of infection, have not emerged. In a study of 69 patients with myeloid malignancies, including 46 patients with acute myeloid leukaemia (AML) and 23 patients with myelodysplastic syndrome (MDS), anti‐spike SARS‐CoV‐2 antibody titres were measured 3 months after the second mRNA‐based vaccination. Seroconversion rates for AML and MDS were 94.7% and 100% respectively, with no significant difference from healthy controls (HCs). Patients with MDS showed a significantly lower antibody titre than that in HCs or AML patients. In AML patients, the antibody titres were comparable to those in HCs when treatment was completed, but lower in patients under maintenance therapy. The response to COVID‐19 vaccine appears to be related to disease and treatment status. Patients with myeloid malignancies may be more responsive to vaccines than patients with lymphoid malignancies.

Abstract
The patient was a 68-year-old woman, diagnosed with acute myelomonocytic leukemia with normal karyotype and FLT3-ITD-negative status in May 2019. She had achieved complete remission (CR) after "7+3" intensive induction chemotherapy and maintained CR by consolidation chemotherapy. However, she relapsed with swelling of the lips and gums in January 2020. She did not achieve CR by salvage chemotherapy with cytarabine-aclarubicin-G-CSF regimen. Comprehensive genomic analysis of leukemic cells revealed the presence of FLT3-N676K mutation, which was undetectable by companion diagnostics at the time. Complete remission with incomplete count recovery was obtained on day 28 after initiation of gilteritinib monotherapy, and the lip and gum swelling improved rapidly. However, she relapsed on day 106 after gilteritinib administration, and gilteritinib was discontinued. Genomic analysis at recurrence revealed NRAS mutation for the first time. Finally, the patient died of the uncontrolled primary disease. This is a case in which comprehensive gene mutation analysis was useful in determining a treatment strategy.

Abstract
The standard treatment for colorectal mucosa-associated lymphoid tissue (MALT) lymphoma has not yet been established due to the rarity of the disease. Here, we report a case of long-term response to chemotherapy for colorectal MALT lymphoma (stage I). A 77-year-old frail female patient with diabetes mellitus and dementia developed melena of unknown etiology, and a colonoscopy was performed at a nearby hospital. A biopsy suggested malignant lymphoma, and she was referred to our department. As a result of re-examination of colonoscopy, a total of 3 submucosal tumor-like lesions were confirmed. Of these, a biopsy of the lesions in the ascending colon and rectum was performed, and MALT lymphoma was diagnosed on the basis of the histopathological findings. Following close examination, no other lymphoma lesions were found, and the patient was diagnosed with primary colorectal MALT lymphoma, stage I. After 1 course of R-THP-COP chemotherapy (rituximab + cyclophosphamide, pirarubicin, vincristine, and prednisone), the rectal lesion was confirmed to have almost disappeared endoscopically, and lymphoma cells were not found histopathologically. The patient was determined to be in complete remission (CR). However, due to hematological toxicity and a slight worsening of glucose control, the second chemotherapy course was changed to the BR regimen (rituximab + bendamustine), and 4 courses were performed (5 total courses of chemotherapy). Currently, >3 years have passed since reaching CR, and the patient is alive without recurrence.

Abstract
In this real-world clinical study, in which we determined eligibility for allogenic hematopoietic stem cell transplantation by prognostic factors and minimal residual disease status, we retrospectively evaluated cytogenetic, genetic, and clinical features in 96 patients with core-binding factor acute myeloid leukemia (CBF-AML) including 62 patients with RUNX1/RUNX1T1 and 34 patients with CBFβ/MYH11. Multivariate analyses for 5-year overall survival (OS) in CBF-AML patients revealed that age of 50 years or older (HR: 3.46, 95% CI 1.47-8.11, P = 0.004) and receiving 2 or more induction cycles (HR: 3.55, 95% CI 1.57-8.05, P = 0.002) were independently associated with worse OS and that loss of sex chromosome (LOS) was independently associated with better OS (HR: 0.09, 95% CI 0.01-0.71, P = 0.022). At the time of complete remission, all 21 karyotyped patients with LOS had a normal karyotype. Furthermore, in all 9 patients with LOS who had a mosaic of metaphase cells with and without t(8;21) or inv(16), the metaphase cells without t(8;21)/inv(16) showed a normal karyotype. These results proved that LOS was not age-related and physiological, but rather a neoplastic chromosomal abnormality.

Abstract
Abstract
Background
Although wild-type transthyretin amyloid cardiomyopathy (ATTRwt-CM) was previously considered a rare disease, recent diagnostic imaging modalities have revealed that it is considerably underdiagnosed among elderly patients with heart failure. The severity of CM is thought to be related to the extent of amyloid deposition in heart.
99mTc-labeled pyrophosphate (99mTc-PYP) scintigraphy, cardiovascular magnetic resonance (CMR), global longitudinal strain (GLS) provide diagnostic and prognostic information in ATTRwt-CM. However, the relevance of these imaging modalities and their association with cardiac amyloid load has not been fully evaluated.
Purpose
The aim of study was to elucidate the associations between pathological amyloid load and cardiac retention evaluated by 99mTc-PYP scintigraphy, CMR, GLS in patients with ATTRwt-CM.
Method
Cardiac amyloid load was calculated as (amyloid deposition area/ total myocardium area)×100 using endomyocardial biopsy specimen. Cardiac retention was quantified by heart to contralateral (H/CL) ratio by 99mTc-PYP scintigraphy. Native T1 and extracellular volume (ECV) were obtained by CMR. GLS was analyzed using the 2D echo at the time of diagnosis.
Result
The mean cardiac amyloid load was 23.0±15.2% (n=57) and correlation with H/CL ratio (1.94±0.36 n=57), native T1 (1426.7±52.5 n=57), ECV (57.9±12.9 n=54), GLS (−9.1±2.4 n=57) were positive (r=0.375 p=0.004, r=0.496 r=0.304 p<0.001, r=0.304 p=0.025, r=0.473 p<0.001).
Conclusion
Increased cardiac amyloid load correlated with an increased 99mTc-PYP positivity, native T1, ECV, and an impaired GLS. These results suggest that imaging parameters may reflect histological and functional changes due to amyloid deposition in the myocardium.

Abstract
Aims
A significant male predominance has been reported in wild-type transthyretin amyloid cardiomyopathy (ATTRwt-CM). In other words, the female ATTRwt-CM may be overlooked and gender differences in ATTRwt-CM remain unclear. This study aims to examine gender differences in clinical characteristics and diagnostic approaches in ATTRwt-CM.
Methods and results
We retrospectively evaluated 171 consecutive ATTRwt-CM patients diagnosed at our university hospital between December 2002 and December 2020. Twenty-two patients (12%) were women. Women were significantly older at diagnosis (77.3 years vs. 83.3 years; P<0.001) and had a higher advanced New York Health Association functional class (2.23±0.70 vs. 2.57±0.81; P=0.04) than men. In echocardiography, mean interventricular septum diameter was less thick (15.8 mm vs. 14.5 mm; P=0.03) and ejection fraction was preserved (51.7% vs. 57.7%; P=0.08) in women. The mean heart-to-contralateral ratio obtained using 99mTc-labeled pyrophosphate (99mTc-PYP) was significantly lower in women than in men (1.89 vs. 1.64; P=0.001). There was no significant gender difference in high-sensitivity median cardiac troponin T levels at diagnosis (0.055 ng/mL vs. 0.069 ng/mL; P=0.30) or history of carpal tunnel syndrome (57% vs. 55%; P=0.93) and electrocardiograms findings. However, the median B-type natriuretic peptide level was significantly higher (254 pg/mL vs. 434 pg/mL; P=0.02) in women. Moderate to severe aortic stenosis was more frequently observed in women (5% vs. 50%; P<0.001). Histological (78% vs. 59%; P=0.07) and genetic confirmation (78% vs. 59%; P=0.003) of ATTRwt-CM were not performed in women.
Conclusion
Women with ATTRwt-CM were predominantly octogenarians, less hypertrophic, and had weaker cardiac uptake of the 99mTc-PYP tracer than men with ATTRwt-CM. These characteristics contribute to the underdiagnosis of ATTRwt-CM in women. The diagnosis of ATTRwt-CM in women is challenging. Therefore, we must be familiar with the clinical characteristics of women with ATTRwt-CM.

Abstract
The treatment of immune thrombocytopenia (ITP) has recently changed; however, each treatment has not only advantages, but also disadvantages, and may have unexpected complications. We describe an instructive case of ITP that was complicated by severe portal vein thrombosis during treatment with eltrombopag, an oral thrombopoietin-receptor agonist (TPO-RA) drug, plus prednisolone (PSL) concomitant splenectomy. A male ITP patient who had been receiving eltrombopag treatment for more than four years at our department underwent a splenectomy at the age of 51. Soon after splenectomy, splenic vein and portal vein thrombosis developed, while splenectomy was ineffective. The patient resumed eltrombopag treatment after thrombosis disappeared. Although fluctuations in PLT were observed, eltrombopag and PSL were used together for a while. Subsequently, lower-limb deep vein thrombosis recurred, and edoxaban tosylate was administered for a total of 8.4 months. More than three years after splenectomy, at the age of 54, abdominal computed tomography (CT) revealed a continuous thrombus extending from the intrahepatic portal vein to the superior mesenteric vein. In patients with ITP in whom splenectomy fails and treatment with a TPO-RA ± PSL needs to be continued, clinicians should be aware of the possibility of abdominal thrombotic adverse events, such as severe portal vein thrombosis, by following-up on CT imaging, not only in the short term but also in the medium-long term.

Abstract
BACKGROUND Phlegmonous gastritis (PG) is a rare bacterial infectious disease characterized by neutrophil-based purulent inflammation of the gastric wall. The most representative causative bacterium is Streptococcus pyogenes, followed by Staphylococcus, Pneumococcus and Enterococcus. Hepatic portal venous gas (HPVG) is considered a potentially fatal condition and is rarely associated with PG.
CASE SUMMARY The white blood cell count of a 70-year-old woman with acute lymphocytic leukemia in complete remission dropped to 100/μL after consolidation chemotherapy. Her vital signs were consistent with septic shock. Venous blood culture revealed the presence of Bacillus cereus. Abdominal computed tomography (CT) and esophagogastroduodenoscopy (EGD) showed marked thickening of the gastric wall. As with the other findings, CT was suggestive of HPVG, and EGD showed pseudomembrane-like tissue covering the superficial mucosa. Histopathological examination of gastric biopsy specimens showed mostly necrotic tissue with lymphocytes rather than neutrophils. Culture of gastric specimens revealed the presence of Bacillus cereus. We finally diagnosed this case as PG with Bacillus cereus-induced sepsis and HPVG. This patient recovered successfully with conservative treatment, chiefly by using carbapenem antibiotics.
CONCLUSION The histopathological finding of this gastric biopsy specimen should be called "neutropenic necrotizing gastritis".

Abstract
The patient developed Stage Ⅳ transverse colon cancer at the age of 72 years and was treated with an 8-course XELOX regimen(capecitabine and oxaliplatin)every 3 weeks after resection. Six years and 9 months after the end of treatment, at the age of 79 years, WBC levels were found to have markedly increased to 10×104/µL in the patient, and acute leukemia was suspected; subsequently, the patient was hospitalized. Bone marrow was aspirated and analyzed, and the results showed that 95% of leukemic cells were positive for esterase staining. Chromosomal examination revealed t(6 ; 11)(q27 ; q23), ie, the diagnosis of therapy-related acute myeloid leukemia(t-AML)with 11q23 abnormality. CR was achieved by chemotherapy, but the disease soon recurred; the patient died 7 months after the onset of t-AML, with the cause being t- AML with 11q23 abnormality that developed 6 years and 9 months after treatment for colorectal cancer with oxaliplatin and capecitabine without undergoing MDS. Since there is a possibility of leukemia induction following oxaliplatin treatment, more such cases need to be monitored in the future.

Abstract
The pathogenesis of autoimmune gastritis (AIG) remains unclear. In addition, it is difficult to follow the process of AIG onset endoscopically. Leukemic non-nodal mantle cell lymphoma (MCL) was newly added as a subtype of MCL in the fourth revised edition of the World Health Organization (WHO) classification (2017). Here, we report a case of AIG associated with the progression of leukemic non-nodal MCL. A 74-year-old woman who had been followed up in a nearby hospital for chronic B-cell lymphoproliferative disorder with no treatment for six years presented with fever and fatigue in the previous one month. The patient was admitted to our department and was diagnosed with leukemic non-nodal MCL. Positron emission tomography-computed tomography examination, which indicated no abnormalities in the six preceding years, revealed uptake in the bone marrow and spleen. Since MCL was progressing, esophagogastroduodenoscopy (EGD), which showed almost no abnormal findings in the gastric mucosa 13 preceding months, was conducted again to search for lesions involving gastrointestinal MCL. Lymphoma lesions were not found, but wide atrophic mucosal changes in the stomach were revealed mainly in the corpus, and patchy redness was also observed in the pylorus, consistent with AIG. The patient tested positive for an anti-gastric parietal cell antibody (×80), her gastrin level was significantly elevated (5,280 pg/mL), and her pepsinogen (PG) I/PG II was considerably less than 1.0 (>3.1). Although no pathological confirmation was obtained by biopsy, the patient was clinically diagnosed with AIG. In our patient, AIG was revealed to be associated with the progression of leukemic non-nodal MCL in this short period.

Abstract
Fms-like tyrosine kinase 3 (FLT3) is one of the most frequently mutated genes in acute myelogenous leukemia (AML) and the mutation is associated with poor prognosis of patients. Two distinct types of activating mutations have been identified in AML samples. One is internal tandem duplications in the juxtamembrane domain (FLT3-ITD) and the other is point mutations in the tyrosine kinase domain (FLT3-TKD). Gilteritinib is a FLT3 inhibitor that inhibits both FLT3-ITD and FLT3-TKD. It was reported that differentiation of leukemic blasts accompanied by differentiation syndrome occurs in some patients treated with gilteritinib. However, information about the precise clinical course is limited, and appropriate management of differentiation syndrome has not been established. We report a case of relapsed AML with FLT3-ITD that was treated with gilteritinib. Analysis of the FLT3-ITD variant allele frequency (VAF) revealed that FLT3-ITD VAF was not decreased despite achievement of complete remission with incomplete hematologic recovery. Remarkable increases of monocytes and granulocytes accompanied by differentiation syndrome were observed at 6 months after the initiation of gilteritinib treatment. Intermittent chemotherapy with low-dose cytarabine and mitoxantrone was effective for reducing myelomonocytosis and resolving differentiation syndrome.

Abstract
BACKGROUND Lycopene has been the object of considerable research attention recently, and the effects of the intake of lycopene, or of tomato products, have been studied in various ways. In Japan, interest in the health-promoting function of food components has increased. OBJECTIVE Developing a method to determine lycopene contents in tomato that meets the Japanese Agricultural Standard (JAS). METHOD In the proposed JAS method, the test sample consists of fresh tomatoes; a hexane-acetone mixture is utilized as the extraction solvent. A collaborative study was conducted to evaluate the interlaboratory performance of the method. RESULTS Ten laboratories participated and analyzed six test materials characterized by a lycopene content between 39 and 170 mg/kg as blind duplicates. After removing statistical outliers, RSDr ranged from 1.2 to 3.0% and RSDR ranged from 2.4 to 4.2%. The HorRat values were calculated and found to be in the 0.26-0.49 range. CONCLUSIONS The method for determining the lycopene content in tomato was evaluated by means of a collaborative study, and the reproducibility of this method was found to be acceptable. HIGHLIGHTS Intended for standardization in Japan, a method to determine lycopene content in tomato has been developed and shown to have acceptable precision in a collaborative study.

Abstract
In Helicobacter pylori−positive, localized primary gastric diffuse large B-cell lymphoma (DLBCL), an increasing number of reports have recently been published on the effectiveness of H. pylori eradication (HPE). However, HPE treatment strategies for gastric DLBCL, including its indications, have yet to be examined. No detailed report has been published on a case of gastric DLBCL unsuccessfully treated by HPE. A 64-year-old female and a 70-year-old male were pathologically diagnosed with chronic active gastritis and mucosa-associated lymphoid tissue lymphoma, respectively. Both patients were positive for H. pylori, so HPE was employed. The disease progressed within 1 year, and both patients were pathologically diagnosed with DLBCL by endoscopic biopsy. On reviewing the first pathology slide, both patients were diagnosed with DLBCL. That is, the 2 patients had primary gastric DLBCL; however, they exhibited progressive disease after HPE. This failure of HPE treatment may be due to the initial lymphomas being multiplex ulcerative lesions. In both cases, complete remission was achieved by chemotherapy (plus radiation therapy) without recurrence for more than 3 years.

Abstract
Background The prognostic nutritional index (pni) is a simple metric calculated using serum albumin and the peripheral lymphocyte count. It was reported that a low pni score is significantly associated with major postoperative complications and poor prognosis. The purpose of the present study was to investigate the effects of perioperative oral management (pom) on the perioperative pni profiles of patients with digestive system or urinary cancers. Study Design The medical records of 181 patients with cancer who underwent surgery and for whom a pni could be calculated were retrospectively reviewed. Results The intervention rate with pom was 34.8%. The median preoperative pni score was 48.25 in all patients with a pom intervention [25% to 75% interquartile range (iqr): 44.38-54.13] and 47.25 in those without an intervention (iqr: 42.0-53.5). Compared with patients not receiving pom, those who received pom had significantly higher pni scores from the early postoperative period (p < 0.05). Notably, of patients who could resume oral intake within 3 days after surgery, those who received pom intervention, compared with those who did not, had significantly higher pni scores from the early postoperative period (p < 0.05). Conclusions Perioperative oral management interventions might have positive effects on the postoperative pni scores of patients with cancer.

Abstract
Eculizumab has been developed as a breakthrough treatment for paroxysmal nocturnal hemoglobinuria (PNH). Not only for breakthroughs, eculizumab therapy is also known to increase the risk of invasive meningococcal infection. It has also been recently reported that, although rarely, administration of eculizumab may result in disseminated gonococcal infection (DGI). We report here a case in which a young patient who had used eculizumab for PNH developed DGI. A 22-year-old Japanese male with PNH who had been treated with eculizumab complained of high fever, mild nausea, headache and right knee joint pain. The patient was admitted and suspected to have sepsis due to meningococcal infection and began to receive ceftriaxone (CTRX). Gonococci were detected in a venous blood culture a few days later, and this case was diagnosed as DGI. CTRX was effective, and the patient was discharged. However, four weeks later, he complained of the same subjective symptoms as at the beginning and was hospitalized again. The presence of gonococcus was proven by venous blood culture, CTRX was re-administered and the patient responded. After discharge, he was counseled on safer sexual activity, including accurate and consistent use of condoms, by urologists. He has not relapsed with DGI for more than one year. When serious signs of infection occur in patients receiving eculizumab, it is recommended to consider DGI as well as invasive meningococcal infection, and CTRX should be given.

Abstract
BACKGROUND Anaplastic large cell lymphoma (ALCL) is a type of T-cell lymphoma that can be divided into two categories: anaplastic lymphoma kinase-positive (ALK+) and ALK-negative. Gastrointestinal ALK+ ALCL is rare. Multiple lymphomatous polyposis (MLP) is thought to be a representative form of gastrointestinal lesion in mantle cell lymphoma, and T-cell lymphomas seldom show this feature. Here, we report the first known case of ALK+ ALCL with gastroduodenal involvement to present with MLP.
CASE SUMMARY The patient was a 43-year-old man who was complained of a mass in the left inguinal area and was performed open biopsy. ALK+ ALCL was diagnosed pathologically. Computed tomography scan demonstrated multiple lymph node lesions in the abdomen - pelvis/inguinal region, and scattered nodular lesions in both lung fields. He did not complain of gastrointestinal symptoms. While, esophagogastroduodenoscopy identified MLP lesions from the antrum of the stomach to the descending portion of the duodenum and mild thickened folds on the corpus of the stomach, and biopsy showed invasion of ALK+ ALCL. We treated this patient with six cycles of CHOEP (Cyclophosphamide, Doxorubicin, Vincristine, Etoposide, and Prednisone) chemotherapy. At the conclusion of treatment, there was complete remission. Numerous white scars were found on the stomach, endoscopically consistent with a remission image of lymphoma. The endoscopic features of this case were thought to be similar to those of MCL.
CONCLUSION The macroscopic/endoscopic features of gastrointestinal ALK+ ALCL may be more similar to those of B-cell lymphomas rather than T-cell lymphomas.

Abstract
Gastrosplenic fistula (GSF) is a rare condition arising from gastric or splenic lymphomas. Surgical resection is the most common treatment, as described in previous reports. We report two cases of GSF in diffuse large B-cell lymphoma (DLBCL) patients that were successfully treated with chemotherapy and irradiation without surgical resection. Case 1 was of a 63-year-old man who had primary gastric DLBCL with a large lesion outside the stomach wall, leading to a spontaneous fistula in the spleen. Case 2 was of a 59-year-old man who had primary splenic DLBCL, which proliferated and infiltrated directly into the stomach. In both cases, chemotherapy comprising rituximab + dose-adjusted EPOCH regimen (etoposide, prednisone, vincristine, cyclophosphamide and doxorubicin) was administered. Case 1 had significant bleeding from the lesion of the stomach during the treatment cycle; however, endoscopic hemostasis was achieved. Case 2 developed a fistula between the stomach and the spleen following therapeutic chemotherapy; however, no complications related to the fistula were observed thereafter. In both cases, irradiation was administered, and complete remission was achieved.

Abstract
Diffuse large B‐cell lymphoma (DLBCL) is the most frequent subtype of non‐Hodgkin lymphoma. High total metabolic tumor volume (TMTV) calculated using 18F‐FDG PET/CT images at diagnosis predicts poor prognosis of patients with DLBCL. However, high cost and poor access to the imaging facilities hamper wider use of 18F‐FDG PET/CT. In order to explore a surrogate marker for TMTV, we evaluated the correlation between the serum levels of soluble interleukin‐2 receptor (sIL‐2R) and TMTV in 64 patients with DLBCL, and the results were verified in an independent validation cohort of 86 patients. Serum levels of sIL‐2R were significantly correlated with TMTV. ROC analysis revealed that the cutoff value of TMTV ≥150 cm3 or sIL‐2R ≥ 1300 U/mL could predict failure to achieve EFS24 with areas under the curve (AUC) 0.706 and 0.758, respectively. Each of TMTV ≥150 cm3 and sIL‐2R ≥1300 U/mL was significantly associated with worse 5‐year overall survival and event‐free survival. Importantly, each of sIL‐2R <1300 U/mL or TMTV <150 cm3 identified patients with favorable prognosis among NCCN‐IPI high‐intermediate and high‐risk group. Serum level of sIL‐2R represents a convenient surrogate marker to estimate metabolic tumor burden measured by 18F‐FDG PET/CT that can predict treatment outcomes of patients with DLBCL.

Abstract
Acquired hemophilia A (AHA) is a rare, hemorrhagic autoimmune disease, whose pathogenesis involves reduced coagulation factor VIII (FVIII) activity related to the appearance of inhibitors against FVIII. Common etiological factors include autoimmune diseases, malignancy, and pregnancy. We report two cases of AHA in solid cancer. The first case is a 63-year-old man who developed peritoneal and intestinal bleeding after gastrectomy for gastric cancer. He was diagnosed with AHA, and was treated with prednisone, followed by cyclophosphamide. In the second case, a 68-year-old man developed a subcutaneous hemorrhage. He was diagnosed with AHA in hepatocellular carcinoma on CT imaging, and treated with rituximab alone. Hemostasis was achieved for both patients without bypassing agents as the amount of inhibitors was reduced and eradicated. However, both patients died within 1 year due to cancer progression. Successful treatment for AHA in solid cancer can be difficult because treatment of the underlying malignancy is also required.

Abstract
OBJECTIVE FGFR3 chondrodysplasia is caused by a gain-of-function mutation of the FGFR3 gene. The disease causes abnormal growth plate cartilage and lacks effective drug treatment. We sought to establish an in vivo model for the study of FGFR3 chondrodysplasia pathology and drug testing. DESIGN We created cartilage from human induced pluripotent stem cells (hiPSCs) and transplanted the cartilage into the subcutaneous spaces of immunodeficient mice. We then created cartilage from the hiPSCs of patients with FGFR3 chondrodysplasia and transplanted them into immunodeficient mice. We treated some mice with a FGFR inhibitor after the transplantation. RESULTS Xenografting the hiPSC-derived cartilage reproduced human growth plate cartilage consisting of zones of resting, proliferating, prehypertrophic and hypertrophic chondrocytes and bone in immunodeficient mice. Immunohistochemistry of xenografts using anti-human nuclear antigen antibody indicated that all chondrocytes in growth plate cartilage were human, whereas bone was composed of human and mouse cells. The pathology of small hypertrophic chondrocytes due to up-regulated FGFR3 signaling in FGFR3 skeletal dysplasia was recapitulated in growth plate cartilage formed in the xenografts of patient-specific hiPSC-derived cartilage. The mean diameters of hypertrophic chondrocytes between wild type and thanatophoric dysplasia were significantly different (95% CI: 13.2-26.9; n = 4 mice, one-way analysis of variance (ANOVA)). The pathology was corrected by systemic administration of a FGFR inhibitor to the mice. CONCLUSION The patient-specific growth plate cartilage xenograft model for FGFR3 skeletal dysplasia indicated recapitulation of pathology and effectiveness of a FGFR inhibitor for treatment and warrants more study for its usefulness to study disease pathology and drug testing.

Abstract
Colorectal follicular lymphoma (FL) occurs less frequently than duodenal-type FL, which is an established entity, and primary multiple FL only involving the colon is rare. Furthermore, the coexistence of lymphoma and multiple myeloma (MM) within the same patient is rare and the current study reports such a case. The patient was an asymptomatic 62-year-old man. He underwent colonoscopy screening, which revealed at least five polypoid tumors from the cecum to the rectum. Biopsy samples stained positive for CD20 and B-cell lymphoma 2 (BCL2) but stained negative for CD10, and fluorescence in situ hybridization analysis identified IGH/BCL2 in 95.2% of the tumor cells. Based on these findings, the patient was diagnosed with FL. On the bone marrow aspirate, the plasma cell count was 30% of all nucleated cells. Bence-Jones κ-type protein was detected by protein electrophoresis in serum and urine. The serum-free light chain κ/λ level was significantly elevated (484.3). Thus, the patient was also diagnosed with MM. Both FL and MM were targeted therapeutically; rituximab and bendamustine were effective for FL, and lenalidomide and low-dose dexamethasone were effective for MM. The patient was treated for 3 years and 7 months and, until now, was off-treatment for 4 years without rapid progression of the two malignancies. Although both diseases are still present, the patient has maintained stable disease. Our findings suggest that lymphoma and MM should be targeted separately as independent hematological malignancies when they occur concurrently.

Abstract
A 74-years-old male who was a smoker and received treatment for hypertension, dyslipidemia, peripheral arterial disease and idiopathic interstitial pneumonia complained of subcutaneous hemorrhage of the right lower thigh. Marked anemia (hemoglobin 5.5 g/dL) and prolonged activated partial thromboplastin time (≥130 seconds) were noted. The factor VIII activity level was reduced to 1.2%, and the factor VIII inhibitor titer was 285.3 BU/mL, a diagnosis of acquired hemophilia A (AHA) was made. Then, hematomas of 5 intra-muscles were recurred. Hemostasis became difficult despite frequent and high-dose administration of recombinant human coagulation factor VIIa (total: 18 days, 305 mg). Hemostasis was achieved by switching to activated prothrombin complex concentrate (for 3 days, 18,000 units), however, cerebral infarction occurred after 36 days. After the frequent administration of bypass hemostatic agents on elderly AHA patients with several risk factors for ischemic stroke, the risk of subsequent thrombotic events may persist for 1 month.

Abstract
Duodenal metastasis from renal cell carcinoma (RCC) is rare. The current case report presents a very rare case of late duodenal metastasis from RCC with newly developed malignant lymphoma (diffuse large B-cell lymphoma: DLBCL) at the same time. A 64-year-old man with systemic lymph nodes swelling who had undergone left nephrectomy for RCC 25 years previously, was admitted to the present hospital. Inguinal lymph node biopsy was performed, leading to a diagnosis of DLBCL. fluorine-18-fluorodeoxy-glucose (18F-FDG)-positron emission tomography (PET)/computed tomography (CT) revealed multiple lymph nodes, spleen, and ileocecal lesions. CT revealed an obvious hypervascular tumor involving the duodenum/pancreatic head. The tumor was false-negative on 18F-FDG-PET/CT. On esophagogastroduodenoscopy, the tumor was detected in the descending portion of the duodenum and was observed to be consistent with the submucosal tumor with a central ulcer, resembling those of ulcer-forming DLBCL. A biopsy was then performed carefully, and a clear cell RCC-derived metastatic cancer was diagnosed. Ileocolonoscopy revealed mucosal thickening of the terminal ileum, and led to a diagnosis of DLBCL infiltration with biopsy. To the best of the author's knowledge, this is the first case report of the coexistence of metastatic cancer from RCC and malignant lymphoma in the small intestine simultaneously. It was necessary to make a careful differential diagnosis in the imaging studies.

Abstract
An 84-year-old man, who had received artificial pneumothorax for pulmonary tuberculosis 67 years previously, complained of severe chest pain. Chest CT revealed chronic pyothorax with multiple heterogeneously enhanced cavity lesions in the wall of the right intrathoracic space. 18FDG-PET revealed that the lesions showed an abnormal uptake. CT-guided biopsy was performed and he was diagnosed with pyothorax-associated lymphoma (PAL); the histological diagnosis was diffuse large B cell lymphoma (DLBCL). Furthermore, immunohistochemical staining revealed that the tumor cells were positive for EBNA-2 and LMP-1, suggesting that the latent gene products of Epstein-Barr virus were associated with the development of PAL. The patient was treated with chemotherapy, including rituximab; however, the treatment was discontinued due to the development of severe delirium after chemotherapy. We should keep in mind that elderly patients with a long history of chronic pyothorax are at risk of developing malignant lymphoma. We report the present case with a brief review of the literature.

Abstract
We herein report the cases of two elderly patients with acquired hemophilia A (AHA) for whom treatment was difficult.An 89-year-old woman (Case 1) was admitted to our department with subcutaneous hemorrhage and melena. Her activated partial thromboplastin time (APTT), factor VIII activity, and factor VIII inhibitor level were 127.7 seconds, 1.0%, and 48 BU/mL, respectively, which was suggestive of AHA. The administration of prednisolone (PSL 0.5 mg/kg) was initiated. After 3 weeks, PSL was combined with cyclophosphamide (CPA 50 mg). Two months after the start of treatment, her factor VIII inhibitor level decreased to 3.4 BU/mL. However, hemorrhagic signs were repeatedly observed during the discontinuation of recombinant activated factor VII (rFVIIa) preparation; bleeding control became insufficient, and pneumonia developed, thus leading to a fatal outcome.An 81-year-old woman (Case 2) was admitted to our department with subcutaneous hemorrhage, anemia (Hb: 9.2 g/dL), and a prolonged APTT (78.7 seconds). Her factor VIII activity was reduced to 0.9%, and her factor VIII inhibitor level was markedly increased to 1,364.9 BU/mL, suggesting AHA. Treatment with PSL (0.5 mg/kg) was initiated. After one month, it was combined with CPA (50 mg); however, her hemorrhagic signs were protracted, and her Hb level decreased to 8.0 g/dL. Subsequently, pneumonia occurred. However, weekly rituximab therapy (375 mg/m2) for 4 weeks decreased her factor VIII inhibitor level, leading to the disappearance of the inhibitor at 1 year and 5 months. During this period, there were no episodes requiring the administration of bypassing agents, such as rFVIIa.

Abstract
Recombinant activated factor VII (rFVIIa) is the bypassing agent used in the first-line hemostatic therapy for acquired hemophilia A (AHA); however, the occurrence of thrombotic complications in rFVIIa-treated AHA patients was recently reported to be 2.9–6.5%. Therefore, the investigation of the proper administration of rFVIIa for AHA is needed. In the present study, we retrospectively investigated the clinical features of AHA with regards to the use of rFVIIa (presence or absence of use and total amount) in 7 AHA patients encountered in our department for 7 years between January 2008 and December 2014. Ages were 63–89 years old (median: 79 years old), and there were 5 male and 2 female patients. The coexistence of cardiovascular risk factors and arteriosclerotic diseases, such as hypertension, diabetes mellitus, and cerebral infarction were present in 6 patients. Anemia progressed to less than 7 g/dL of hemoglobin and required red blood cell transfusion in 5 patients, showing “severe” hemorrhage. Factor VIII inhibitors were removed by immunological treatments in 6 patients. As a hemostatic therapy, rFVIIa was used in 4 patients. rFVIIa was not administered or was administered at a very low dose (20 mg) to 3 and 1 patient, respectively, and bleeding stopped as inhibitor titers decreased and disappeared in these patients. Inhibitors did not disappear in 1 patient and the control of hemostasis became poor and was accompanied by intestinal hemorrhage. Although a large amount of rFVIIa (265 mg in total) was administered, the patient bled to death. Therefore, bleeding may be stopped without the administration of rFVIIa in some AHA cases, while the dose of rFVIIa is not necessarily related to hemostatic effects in other cases. Since the main aim of AHA treatments is the removal of inhibitors, caution is needed to ensure that more than the necessary amount of rFVIIa is not administered.

Abstract
We report a case of primary gastric diffuse large B-cell lymphoma (DLBCL), de novo DLBCL without the features of mucosa-associated lymphoid tissue (MALT) lymphoma, which regressed after Helicobacter pylori (HP) eradication. A 27-year-old Japanese female with epigastralgia was revealed to have ulcerated lesions in the angle and antral regions on gastroscopy. Biopsy specimen was consistent with a diagnosis of DLBCL without MALT lymphoma component, indicating de novo development. Her clinical staging on the Lugano system was Stage I. HP was positive on a rapid urease test, and she received HP eradication therapy twice, because the first therapy was not successful. On gastroscopy performed 1 month after the second HP eradication therapy, no ulcerated lesion was noted, and the lymphoma cells had regressed histopathologically.

Abstract
We report a patient who had dural arteriovenous fistulae in the region of the foramen magnum with repeated subarachnoid haemorrhage. Magnetic resonance imaging revealed abnormal vascular structures on the right side of the medulla oblongata in an extra-axial portion. Angiographic findings showed that the lesion was supplied from the meningeal arteries and drained directly into the subarachnoid vein. There was venous dilatation. Embolisation was performed via the transarterial approach using a micro coil and liquid material. Three years after treatment, the patients' condition is good and follow-up angiograms confirmed the stability of the treatment outcome. While dural arteriovenous fistulae of the foramen magnum are rare, this malformation results in a high rate of bleeding and requires treatment.

Abstract
Multiple lymphomatous polyposis (MLP) is an uncommon type of gastrointestinal lymphoma characterized by the presence of multiple polyps along the gastrointestinal tract. Most of this entity is in fact considered the counterpart of gastrointestinal tract involvement for mantle cell lymphoma (MCL). To our knowledge, there have been no reports on [fluorine-18]-fluorodeoxy-glucose (18F-FDG)-positron emission tomography (PET)/computed tomography (CT) imaging for gastrointestinal MCL with MLP. We present the results of 18F-FDG PET/CT imaging in a patient with gastrointestinal tract involvement of MCL showing continuous MLP from the stomach to the rectum and intestinal intussusception. FDG-PET/CT findings were false negative in typical MLP spreading widely over the gastrointestinal tract, but uptake was noted in large lesions with deep infiltration considered atypical as MLP. On FDG-PET/CT imaging, the Ki-67 proliferative index, which is a cell proliferation marker, showed neither correlation with the presence of uptake nor the maximum standardized uptake value.

Abstract
Tyrosine kinase inhibitors (TKIs) are highly effective in the treatment of chronic myelogenous leukemia (CML), but there have been a few adverse event reports describing gastrointestinal bleeding. We clinically analyzed two patients who developed intestinal bleeding during the administration of TKIs for CML. Platelet counts of both patients were normal. The patients showed endoscopic findings characterized by mildly hemorrhagic mucosa. The imatinib patient was diagnosed by capsule endoscopy of the small intestine, and required frequent blood transfusions. The dasatinib patient showed occult bleeding due to CD8-positive colitis. We should adequately recognize that gastrointestinal bleeding may occur during the administration of TKIs.

Abstract
Biphenotypic acute leukemias (BAL) account for less than 4% of all cases of acute leukemia. Philadelphia chromosome and 11q23 rearrangement are the most frequently found cytogenetic abnormalities. Since t(15;17) is almost always associated with acute promyelocytic leukemia, t(15;17) in BAL cases is extremely uncommon. We report here a rare and instructive case of BAL with t(15;17) and the successful treatment approach adopted. A 55-year old woman was referred to our hospital for an examination of elevated white blood cell (WBC) counts with blasts (WBC 13.4×10(9)/L; 76% blasts). The blasts with acute lymphoblastic leukemia (ALL-L2, FAB) morphology co-expressed B-lymphoid and myeloid lineages, and a cytogenetic study revealed 4q21 abnormalities and t(15;17). However, promyelocytic-retinoid acid receptor α rearrangement was not detected by fluorescence in situ hybridization on interphase nuclei. Our patient was treated with chemotherapy for ALL and gemtuzumab ozogamicin without all-trans-retinoic acid, and has remained in hematologic first complete remission for more than 3.7 years.

Abstract
A modified technique is required in patients with wide-necked aneurysms whose treatment by the single microcatheter technique is difficult. We developed a 6-Fr guiding catheter (Slim Guide(®)) that features a large lumen (0.072 inch) for performing the modified technique. To evaluate the usefulness of Slim Guide(®) we carried out experiments using three types of 6-Fr guiding catheter. In experiment 1, the shaft hardness and kink resistance were compared among three different guiding catheters (Slim Guide(®), Launcher(®), Envoy(®)). In experiment 2, we inserted a microballoon catheter and a microcatheter into the three different guiding catheters and recorded the maximal infusion pressure. In experiment 3, we inserted 13 different types of microdevices into the three different guiding catheters and evaluated the resistance of the microdevices. Although the shaft of the Slim Guide(®) was softer than that of the other two guiding catheters, its kink resistance was comparable. The maximal infusion pressure was significantly lower than with Launcher(®) or Envoy(®) catheters. Furthermore, with Slim Guide(®), in 136 of 143 microdevice combinations examined (95.1%) there was no resistance; this was true for 125 (87.4%) and 116 (81.1%) combinations using the Launcher(®) - and the Envoy(®) guiding catheters, respectively. There was a significant difference between Slim Guide(®) and the other two guiding catheters with respect to their accommodation of double microsystems (p<0.05). Although the inner diameter of Slim Guide(®) is slightly larger than of the other two guiding catheters, it significantly increased the combination of microdevices that could be used for the coil embolization of difficult aneurysms.

Abstract
To identify the molecular characteristics specific to the mushroom body (MB, a higher processing centre) neurones in the honeybee brain, we previously used proteomics to identify proteins that are preferentially expressed in these MBs. Here we continued our proteomic analysis to show that reticulocalbin, which is involved in endoplasmic reticulum (ER) Ca(2+) transport, is also preferentially expressed in the MBs in the honeybee brain. Gene expression analysis revealed that reticulocalbin is preferentially expressed in the large-type Kenyon cells, which are MB-intrinsic neurones. In addition, the gene for the ryanodine receptor, which is also involved in ER Ca(2+) transport, was also preferentially expressed in the large-type Kenyon cells. In contrast, the expression of three other ER-related genes, protein disulphide isomerase, sec61 and erp60, was not enriched in the MBs. These findings further support the notion that the function of ER Ca(2+)-signalling, but not the mere intracellular density of ER, is specifically enhanced in the large-type Kenyon cells in the honeybee brain.
