Abstract
BACKGROUND Diffuse large B-cell lymphoma sometimes involves the endocrine organs, but involvement of both the pituitary and adrenal glands is extremely rare. Involvement of these structures can lead to hypopituitarism and adrenal insufficiency, and subsequent recovery of their function is rarely seen. The present report describes an extremely rare case of pituitary and adrenal diffuse large B-cell lymphoma presenting with hypopituitarism and adrenal insufficiency with subsequent recovery of pituitary and adrenal function after successful treatment of the lymphoma. CASE PRESENTATION A 63-year-old Japanese man was referred to our hospital due to miosis, ptosis, hypohidrosis of his left face, polydipsia and polyuria. 18F-fluorodeoxy glucose positron emission tomography / computed tomography revealed hotspots in the pituitary gland, bilateral adrenal glands and the apex of his left lung. Surgical biopsy from the pituitary lesion confirmed the diagnosis of diffuse large B-cell lymphoma, with lymphoma cells replacing normal pituitary tissue. Endocrine function tests revealed adrenal insufficiency and panhypopituitarism, including a possible affection of the posterior pituitary. Hormone replacement therapy with desmopressin and hydrocortisone was started. Chemotherapy consisted of six courses of R-CHOP (rituximab, cyclophosphamide, vincristine, doxorubicin and prednisolone) and two courses of high-dose methotrexate followed by autologous hematopoietic stem cell transplantation. Subsequently, his pituitary and bilateral adrenal lesions resolved, and serial endocrine function tests showed gradual improvement in pituitary and adrenal function. CONCLUSIONS The present report describes an extremely rare case of diffuse large B-cell lymphoma with involvement of both the pituitary and bilateral adrenal glands. R-CHOP and high-dose methotrexate therapy followed by autologous hematopoietic stem cell transplantation was quite effective, and panhypopituitarism and adrenal insufficiency improved to almost normal values after successful treatment of the lymphoma with chemotherapy.

Abstract
Transfusion-related acute lung injury (TRALI) is a severe pulmonary complication following blood transfusions. We experienced a case of possible TRALI during the course of EBV-associated hemophagocytic lymphohistiocytosis (EBV-HLH). A 19-year-old woman was admitted to our hospital suffering from fever and abdominal pain. Her laboratory data revealed pancytopenia, liver damage, coagulopathy, and a high titer of EBV-DNA. Computed tomography showed hepatosplenomegaly and bone marrow aspiration revealed hemophagocytosis and the proliferation of atypical lymphocytes. A diagnosis of EBV-HLH was made and plasma exchange was performed. Severe hypoxia due to pulmonary edema developed two hours after starting the plasma transfusion. Methylprednisolone pulse therapy and non-invasive positive pressure ventilation ameliorated her respiratory condition. Anti-HLA class I and II antibodies were detected in donor sera and a cross-match test between patient lymphocytes and donor plasma was positive. To the best of our knowledge, this is the first case report of TRALI complicated with EBV-HLH. It is possible that hypercytokinemia accompanied by HLH was associated with the onset of TRALI.

Abstract
Intravenous injection of bendamustine often causes venous irritation and also deteriorates the patient's quality of life. Thus, we evaluated the risk factors associated with venous irritation induced by bendamustine in patients with follicular lymphoma or mantle cell lymphoma. We also evaluated the effectiveness of intervention of changing the preparation procedure for bendamustine. All data were retrospectively collected from the electronic medical record system. In the initial analysis of the total 43 courses of bendamustine therapy, most patients (88%) were administered bendamustine with 250 mL of diluent according to the bendamustine package insert in Japan. The median concentration of bendamustine solution (0.56 mg/mL vs. 0.24 mg/mL) and the incidences of venous irritation (66% vs. 0%, p=0.01) were significantly different between the patients receiving bendamustine at 250 mL and 500 mL of diluent. Based on this result, we proposed changing the final volume of bendamustine dissolution from 250 to 500 mL, which is recommended in other countries. After this intervention, the incidence of venous irritation was significantly reduced from 58 to 20% (p=0.02). The incidence of venous irritation increased in a concentration-dependent manner (≤0.40 mg/mL: 6%; 0.41-0.60 mg/mL: 62%, p<0.001; >0.60 mg/mL: 75%, p<0.001). We conclude that a high concentration bendamustine solution is a risk factor for venous irritation and that 500 mL of diluent is ideal. To further reduce the incidence of venous irritation, the concentration of bendamustine solution is recommended to be 0.40 mg/mL or less.

Abstract
We measured plasma levels of thrombopoietin (TPO) in several patients with thrombocytopenia. Similar to previous reports, TPO levels in aplastic anemia (N=9) were markedly higher than those in idiopathic thrombocytopenic purpura (N=10): 16.19+/-9.07 fmol/ml and 1.21+/-1.06 fmol/ml, respectively. In patients with secondary failure of platelet recovery (N=7) as well as primary failure after hematopoietic stem cell transplantation, TPO levels were very high, reflecting impaired platelet production due to GVHD, drug treatments, and infection. When using new drugs such as TPO-receptor agonists, measurement of TPO levels might be important to differentiate the mechanism of thrombocytopenia.

Abstract
Recent reports have shown that gamma-knife radiosurgery provides a safe and effective strategy for the management of brain tumors. To evaluate the role of stereotactic radiosurgery in the management of meningiomas, we investigated the histopathology of two patients. The patients, a 37-year-old man and a 54-year-old woman, presented with visual field disturbance or headache. Imaging studies demonstrated intracranial meningiomas--tentorial and sphenoid ridge, respectively. Each patient undewent subtotal surgical resection (more than 90% in both patients), followed by gamma-knife radiosurgery of the remnant tumor marginal doses of 15 Gy. Pathological examination of the original tumors revealed a meningothelial meningioma and an atypical meningioma, respectively. Enlargement of the remnant tumors 4 months after radiosurgery resulted in total surgical resection in both patients. Thirteen months later, the patient with the atypical meningioma underwent a third operation for early recurrence of the tumor. Histopathology was investigated, and MIB-1, p53, and bcl-2 labeling indexes (LI) were analyzed immunohistochemically. Histopathologically, the specimens showed necrosis and intratumoral vessel obliteration after radiosurgery in both cases. However, more remnant tumor cells survived in the atypical meningioma. Immunohistochemically, increased wild-type p53, decreased bcl-2 expression, and decreased MIB-1 LI were observed in the benign meningioma. In the atypical meningioma, on the contrary, MIB-1 LI was decreased and mutant-type p53 and bcl-2 expression were unchanged. The specimen from the third operation revealed an anaplastic meningioma, and MIB-1 LI was markedly increased. These findings suggest that the efficacy of radiosurgery may differ between benign and atypical meningiomas.

Abstract
Background: There are no established biomarkers to identify tumour recurrence in stage II colon cancer. As shown previously, the enzymatic activity of the cyclin-dependent kinases 1 and 2 (CDK1 and CDK2) predicts outcome in breast cancer. Therefore, we investigated whether CDK activity identifies tumour recurrence in colon cancer. Methods: In all, 254 patients with completely resected (R0) UICC stage II colon cancer were analysed retrospectively from two independent cohorts from Munich (Germany) and Leiden (Netherlands). None of the patients received adjuvant treatment. Development of distant metastasis was observed in 27 patients (median follow-up: 86 months). Protein expression and activity of CDKs were measured on fresh-frozen tumour samples. Results: Specific activity (SA) of CDK1 (CDK1SA), but not CDK2, significantly predicted distant metastasis (concordance index=0.69, 95% confidence interval (CI): 0.55–0.79, P=0.036). Cutoff derivation by maximum log-rank statistics yielded a threshold of CDK1SA at 11 (SA units, P=0.029). Accordingly, 59% of patients were classified as high-risk (CDK1SA ⩾11). Cox proportional hazard analysis revealed CDK1SA as independent prognostic variable (hazard ratio=6.2, 95% CI: 1.44–26.9, P=0.012). Moreover, CKD1SA was significantly elevated in microsatellite-stable tumours. Conclusion: Specific activity of CDK1 is a promising biomarker for metastasis risk in stage II colon cancer.

Abstract
BACKGROUND We established the cell cycle profiling (C2P) assay for specific activity (SA; activity/expression) of cyclin-dependent kinases (CDKs). C2P risk score (C2P-RS) based on CDK1 and CDK2 SAs was significantly associated with relapse in breast cancer (BC). This study was conducted to investigate the predictive value of C2P-RS for neoadjuvant chemotherapy (NAC). PATIENTS AND METHODS Among 124 eligible patients, 122 were treated with weekly paclitaxel followed by 5-fluorouracil, epirubicin and cyclophosphamide (P-FEC) and 2 were treated with paclitaxel monotherapy. C2P-RS was determined via C2P using frozen biopsy samples before NAC. RESULTS Negative estrogen receptor (ER), negative progesterone receptor (PR), positive human epidermal growth factor receptor 2 (HER2), high Ki-67 expression and intermediate + high C2P-RS were significantly associated with high pathological complete response (pCR) rates compared with positive ER (30% versus 9%), positive PR (25% versus 6%), negative HER2 (34% versus 11%), low Ki-67 expression (24% versus 7%) or low C2P-RS (24% versus 9%), respectively. The combination of C2P-RS and Ki-67 had a stronger impact on pCR than each parameter alone, and a multivariate analysis showed that the combination was an independent predictor of pCR (odds ratio 3.3, 95% confidence interval 1.1-9.5). CONCLUSIONS C2P-RS was significantly associated with pCR after P-FEC and may be a useful predictor for chemotherapy in BCs.

Abstract
AIMS The aim of this study was to isolate a thermotolerant micro-organism that produces polyhydroxyalkanoates (PHAs) composed of medium-chain-length (mcl) HA units from a biodiesel fuel (BDF) by-product as a carbon source. METHODS AND RESULTS We successfully isolated a thermotolerant micro-organism, strain SG4502, capable to accumulate mcl-PHA from a BDF by-product as a carbon source at a cultivation temperature of 45°C. The strain could also produce mcl-PHA from acetate, octanoate and dodecanoate as sole carbon sources at cultivation temperatures up to 55°C. Taxonomic studies and 16S rRNA gene sequence analysis revealed that strain SG4502 was phylogenetically affiliated with species of the genus Pseudomonas. This study is the first report of PHA synthesis by a thermotolerant Pseudomonas. CONCLUSIONS A novel thermotolerant bacterium capable to accumulate mcl-PHA from a BDF by-product was successfully isolated. SIGNIFICANCE AND IMPACT OF THE STUDY A major issue regarding industrial production of microbial PHAs is their much higher production cost compared with conventional petrochemical-based plastic materials. Especially significant are the cost of a fermentative substrate and the running cost to maintain a temperature suitable for microbial growth. Thus, strain SG4502, isolated in this study, which assimilates BDF by-product and produces PHA at high temperature, would be very useful for practical application in industry.

Abstract
Microsurgical anatomy for lateral approaches to the foramen magnum, especially for transcondylar fossa (supracondylar transjugular tubercle) approach, was studied using cadavers. The transcondylar fossa approach is an approach in which extradural removal of the posterior portion of the jugular tubercle through the condylar fossa is added to the far lateral approach. Some differences between this approach and the transcondylar approach are demonstrated. The atlanto-occipital joint and the jugular tubercle are obstacles for the lateral approaches. The condylar fossa forming the external occipital surface of the jugular tubercle is located supero-posterior to the occipital condyle. The fossa is limited laterally by the sigmoid sulcus and the jugular foramen. The posterior condylar canal communicating anteriorly with the distal end of the sigmoid sulcus, the jugular foramen, or the hypoglossal canal opens at the bottom of the fossa. The condyle is situated inferior to the posterior condylar and hypoglossal canals, and the jugular tubercle is located superior to them. In the transcondylar fossa approach the posterior part of the jugular tubercle is extradurally removed, but the condyle and the atlanto-occipital joint are untouched. On the other band, in the transcondylar approach the medial parts of the condyle and the lateral mass of Cl are removed. The latter approach offers better visualization of the inferior part of the foramen magnum. The essential difference of the two approaches is in the direction of looking and the extent of resection of the atlanto-occipital joint. Both approaches offer excellent view of the ventral dural space in the lower clivus and the foramen magnum, but the level of exposure differs somewhat between them. In the lateral approaches to the foramen magnum, the condylar fossa, the posterior condylar canal, and the posterior condylar emissary vein all play an important role as intraoperative anatomical landmarks.

Abstract
This study was performed to determine if the arcuate eminence can be drilled down without opening the semicircular canal to obtain a flatter operative field during an anterior or posterior transpetrosal approach. The depth of the superior semicircular canal from the top of the arcuate eminence was measured in 43 dry temporal bones. We found that the arcuate eminence was situated approximately 20 mm from the petrosigmoid intersection, and the superior semicircular canal was located 2.0 mm deep from the top of the arcuate eminence (range, 0.2 mm to 4.2 mm). The arcuate eminence consists of either (1) the otic capsule and additional overlying bone, (2) the naked otic capsule of normal thickness, or (3) the thinned otic capsule. In cases strictly selected by preoperative computed tomography, it may be possible to drill down the arcuate eminence with meticulous manipulation. The relationship between opening the semicircular canal and hearing preservation is also discussed.

Abstract
INTRODUCTION T-helper cell type 1 (Th1) polarization of the immune response has been documented in patients with chronic immune thrombocytopenia (ITP). Interleukin (IL)-10 is the most important factor regulating Th1 and T-helper type 2 cytokine synthesis. This study evaluated the impact of IL-10 polymorphisms on both susceptibility to, and severity of, chronic ITP. METHODS We analyzed -1082(G/A), -812(C/T), and -592(C/A) IL-10 polymorphisms in 90 patients with adult chronic ITP and 202 race- and sex-matched healthy controls. RESULTS No significant differences in the genotype or haplotype frequencies were observed between the patient with chronic ITP and the control group. However, more patients with the -592AA genotype showed a severe thrombocytopenic state (platelet count <10 x 10⁹/l) than those with the -592CC/CA genotypes (44.1%vs. 19.6%, P = 0.01). Furthermore, more patients with the ATA/ATA haplotype showed a severe thrombocytopenic state than those without the ATA/ATA haplotype (44.1%vs. 19.6%, P = 0.01). CONCLUSION According to our data, patients with low producer type of IL-10 polymorphisms have more severe thrombocytopenia, suggesting that IL-10 gene polymorphisms may reflect the severity of ITP.

Abstract
341 Background: We established original methods enabling simultaneous analysis of protein expressions and kinase activities of the CDK (cyclin-dependent kinase) molecules in lysate of tumor tissue in a clinical setting (C2P technology, Ishihara et al: Biochim Biophys Acta. 1741; 226-233, 2005). The clinical utility of the technology was first evaluated in breast cancer, and combination analysis of CDK1 and CDK2 activity was shown to be a significant prognostic indicator for relapse (Kim et al. Ann Oncol. 19;68-72,2009). The objective of our study is to evaluate the efficacy of CDK1 and CDK2 activity as a prognostic marker in human renal cell carcinoma (RCC). Methods: Surgical specimens were obtained from 115 patients with RCC without metastasis. These patients were selected randomly for this study. Protein expression and kinase activity of CDKs and cyclins were analyzed using a newly developed assay system. The system to measure the CDK specific activity (SA) is named C2Ps (Sysmex, Kobe, Japan). We then examined the specific activities of CDK1 and CDK2 and calculated CDK2/CDK1 ratio in RCC. Also, risk score (RS) was examined as described in previous study (JGH van Nes et al: Br J Cancer. 100; 494-500, 2009). Cut off value was calculated by ROC analysis. Results: 115 cases were tested, though 32 cases were excluded of low sample quality (30 cases) and of assay failure (2 cases). 83 cases were analyzed. They included 63 male and 20 female patients, ranging in age from 19 to 83 years. At a median follow up of 33 months (1-109M), tumor with low CDK2/CDK1 ratio showed significantly better 5-year progression-free survival (PFS) than those with high CDK2/CDK1 ratio (91.2% vs. 51.6%, p=0.0016). Also, RS enabled the classification of RCCs into high-risk and low-risk groups, patients with tumors classified as low RS showed better PFS than patients with tumors with high RS (88.9% vs. 63.9%, p=0.0488). Conclusions: CDK1 specific activity of tumors and the CDK2 specific activity are both associated with recurrence and prognosis. Analysis of cyclin-dependent kinase activity in the clinical setting could be a powerful approach for predicting cancer recurrence and prognosis in RCC after surgery and has potential for use as a routine laboratory test.

Abstract
Arterial spin-labeling (ASL) magnetic resonance imaging (MRI) enables non-invasive acquisition of the brain perfusion information in cerebrovascular disease. We investigated hemodynamic changes in intracranial dural arteriovenous fistulas (DAVFs) using ASL-MRI. ASL-MRI by a Q2TIPS sequence on a 3.0-Tesla MRI was performed for three patients with Cognard's IIa+b type of DAVFs before and after treatment. Perfusion images obtained by ASL-MRI (ASL images) before treatment were visually compared with those by single-photon emission computed tomography images (SPECT images). Increasing rates of temporal changes of regional perfusion values in ASL images (ASL values) before and after treatment were also calculated. In all three patients, ASL images before treatment demonstrated high perfusion in regions around the shunting areas, where normal or low perfusion were detected on SPECT images; thus, ASL images might have demonstrated the abundant arterial shunting flow via the fistulas. On days eight to 20 after treatment, ASL values around the shunt areas remained the same or decreased, and those in the regions other than the shunt areas increased in all three patients. This might have been due to a combination of the following: a decrease in shunt flow volume, an amelioration of venous congestion, and a sustained an upward shift in the autoregulation of the brain perfusion pressure. All regional ASL values decreased on days 112 and 120 after treatment in two patients, which possibly reflects a reduction in the upward shift in autoregulation. ASL-MRI might be useful for identifying the hemodynamic behavior of DAVFs before and after treatment.

Abstract
Background: We have reported that breast tumors with a high ratio of cyclin-dependent kinase (CDK) 2 to CDK 1 are associated with high tumor cell proliferation and poor clinical outcome in Japanese. In addition, we have developed risk score based on CDK2/1 ratio (CDK-RS), and have demonstrated a high risk group showed a significantly poor prognosis in Hollanders (van Nes, et al: Br J C 2009: 100: 494). The aim of the present study is to evaluate the correlation of CDK-RS with response to neoadjuvant paclitaxel followed by fluorouracil + epirubicin + cyclophosphamide (FEC) in breast cancers.
Material and Methods: Of 131 primary breast cancer patients (age: 25-73y, mean: 51.7y), 126 were treated with paclitaxel (80 mg/m2, weekly) for 12 cycles followed by FEC (500/75/500 mg/m2, q3w) for four cycles and 5 were treated with paclitaxel-monotherapy (5 — 29 cycles) in the NAC or primary chemotherapy setting. Frozen tumor tissues were obtained from core needle biopsy before NAC, and CDK-RS was determined by the Cell Cycle Profiling (C2P) assay as previously reported. Clinical response was evaluated with MRI before NAC and after paclitaxel and FEC. Patients were classified into responders showing ≥80 % in reduction rates and non-responders showing < 80 %. Pathological CR (pCR) was defined as no residual invasive foci and no axillary lymph node metastasis. Results: Patients characteristics were as follows: menopausal status: pre-47%, post-53%; Stage: II 68%, III 27%, IV 7%; Tumor size (cm): ≥5 cm 73%, > 5 cm 27%; histologic grade (HG): I 16%, II 60%, III 24%; ER: (+) 56%, (-) 44%; PR: (+) 39%, (-) 61%; HER2: (+) 28%, (-) 72%. Of 131 patients, 22 (18%) attained pCR but 100 (82%) did not pCR (9 were excluded from evaluation of pathologic response because of stage IV diseases, no operations, and not available pathologic examination). In CDK-RS, 47% of 131 tumors were classified into high, 17% intermediate, and 37% low. In combination with high + intermediate risk score groups, that group had a tendency to show high HG (grade 2 or 3) (87% vs 78%), ER negativity (49% vs 35%), and PR negativity (65% vs 54%) compared with a low risk group, but their differences were not statistically significant. Tumors in the high + intermediate group were significantly more likely to show clinical response after the completion of not only paclitaxel (52% vs 27%, p=0.006) but also FEC (75% vs 52%, p=0.011) as well as to show pCR (24% vs 9%, p=0.037) compared with a low risk score group. In univariate analysis, CDK-RS showed a significant correlation with pCR (high + intermediate vs low, Odds ratio 4.03, 95%CI 1.03 — 10.3, p=0.045).
Discussion: CDK-RS in tumor samples before NAC is significantly associated with clinical and pathological response to paclitaxel followed by FEC. Thus CDK-RS seems to be a novel and useful predictive factor for paclitaxel — FEC in breast cancers.

Abstract
BACKGROUND AND PURPOSE The "ivy" sign that is identified on FLAIR images in patients with Moyamoya disease is considered to be leptomeningeal collaterals. The aim of our study was to evaluate the correlation between postoperative decrease in ivy sign and cerebral hemodynamic status in the bypass-established hemisphere. MATERIALS AND METHODS Twenty-two patients with Moyamoya disease were enrolled. Postoperative changes in the ivy sign on FLAIR images were examined in each patient after bypass surgery. The correlation between postoperative changes in the ivy sign and hemodynamic status was examined in 10 patients by using SPECT. RESULTS Of the 22 preoperative ivy-positive patients, 21 showed decreased ivy signs on the operative side. Average intervals between the operation day and the date when the decreased or vanished ivy sign was first recognized were 157.6 days in patients who underwent direct bypass and 212.2 days in patients who underwent indirect bypass. A postoperative decrease in ivy signs was found to be significantly correlated with an improved hemodynamic status of the surgically treated hemisphere, resulting in a postoperative increase in regional vascular reserve and a decreased proportion of the misery perfusion area (P < .01). CONCLUSIONS Postoperative changes in the ivy sign can be used as a marker for identifying improved hemodynamics and also for testing the effectiveness of cerebral revascularization.
