Abstract
Ten temporomandibular joints (TMJs) of 5 healthy volunteers and 19 TMJs of internal derangements in 16 patients with splint therapy were examined with MR imaging. T1-weighted images were obtained only in the closed mouth position, and gradient recalled acquisition in steady state (GRASS) images were obtained in active opening and closing phases, allowing a pseudodynamic display of TMJ movement. All patients received protrusive splint treatment. The usefulness of MR imaging to assess the efficacy of splint therapy was evaluated. Corrected disk position with the splint in place was clearly demonstrated in 9 TMJs, corresponding with elimination of reciprocal clicking. Ten other TMJs of anterior disk displacement without reduction showed uncorrected disk position by the splint. This information could confirm the therapeutic efficacy, or suggest other treatment alternatives. GRASS MR imaging can provide accurate and physiologic information about disk function in initial and follow-up assessment of protrusive splint therapy.

Abstract
Diffusion tensor imaging (DTI) is a magnetic resonance (MR) technique used to analyze diffusion anisotropy of the central nervous system (CNS) and can demonstrate subtle white matter anatomy. In particular, tractography is expected to be a unique, non-invasive tool to provide more pertinent insights into brain structure and orientation not accessible with conventional MRI. Data collection was performed in a normal volunteer on a 1.5-T MRI system using several techniques including six axis single-shot echo planar imaging (EPI), over six axis EPI, and periodically rotated overlapping parallel lines with enhanced reconstruction techniques. Tractography was generated by a continuous tracking method with our original software, Volume-One (for viewing volumetric image data) and VizDT-II (for analysis of DTI data). Using these data, estimated tracts were generated in arcuate fibers of cerebrum, cingulum, superior longitudinal fasciculus, uncinate fasciculus, inferior longitudinal fasciculus, corpus callosum, fornix, anterior thalamic radiation, central thalamic radiation, thalamo-parietal fibers, optic radiation, superior cerebellar peduncle, middle cerebellar peduncle, inferior cerebellar peduncle and intrinsic commissure paths of the hipoccampous. DTI including tractography allows differentiation between complex white matter tracts. The information regarding the detailed relationship may be useful for diagnosis of the location and extent of brain lesions, and preoperative planning.

Abstract
Fifteen patients with acute ruptured intracranial aneurysms were treated with interlocking detachable coil (IDC) embolization. All graded poorly, i.e., Hunt & Kosnik grades IV and V. Aneurysm occurred in the anterior circulation in 14 patients and at the basilar tip in one, of these, 13 were small and 2 large. The endovascular procedure was conducted in a transfemoral approach under local anesthesia. Aneurysmal obliteration was examined transitionally after embolization. Final outcome was evaluated using the Glasgow outcome scale (GOS). Total aneurysmal occlusion was observed immediately after IDC embolization in 11 patients. Two cases of coil migration to the parent artery occurred during endovascular procedure in patients with severe atherosclerosis. Aneurysmal rupture occurred during the endovascular procedure in a small internal carotid artery aneurysm when coil detachment failed. Follow-up angiography showed coil compaction in 2 patients, one patient experienced deterioration when the aneurysm ruptured. Eleven patients (73.3%) retained total aneurysmal occlusion and had no rebleeding. The overall GOS indicated good recovery in 5 patients, severe disability in 2, persistent vegetative state in 2, and death in 6. IDC embolization in severe acute ruptured intracranial aneurysm successfully prevented rebleeding, but our series was limited by the very small aneurysm size and the presence of severe atherosclerosis.

Abstract
In total, 310 rice blast (Pyricularia oryzae Cavara) isolates from Japan showed wide variation in virulence. Virulence on rice (Oryza sativa L.) differential varieties (DV) harboring resistance genes Pish, Pia, Pii, Pi3, Pi5(t), Pik-s, and Pi19(t) ranged from 82.9 to 100.0%. In contrast, virulence on DV possessing Pib, Pit, Pik-m, Pi1, Pik-h, Pik, Pik-p, Pi7(t), Pi9(t), Piz, Piz-5, Piz-t, Pita-2, Pita, Pi12(t), and Pi20(t) ranged from 0 to 21.6%. Cluster analysis using the reaction patterns of the DV classified isolates into three groups: I, virulent to Pik, Pik-h, Pik-p, Pik-m, Pi1, and Pi7(t); IIa, avirulent to the preceding 6 genes and virulent to Pia, Pii, Pi3, and Pi5(t); and IIb, avirulent to all 10 genes. Group I was limited to northern Japan and group IIb to central Japan, while group IIa was distributed throughout Japan. We estimate that group IIa represents the original population and that groups I and IIb arose from it through minor changes in pathogenicity. We classified these isolates into 123 races by a new designation system and conclude that the rice blast races in Japan are less diverse than previously thought.

Abstract
Introduction New-onset systemic lupus erythematosus (SLE) during pregnancy is rare and difficult to diagnose, especially in cases that manifest as preeclampsia. We report a patient with new-onset SLE that manifested as preeclampsia during pregnancy and provide a review of the literature to identify factors for a rapid diagnosis. Case A 32-year-old primigravid Japanese woman was diagnosed with severe preeclampsia and underwent emergent cesarean section at 29 weeks of gestation. Her hypertension and renal disorder gradually improved after the operation, but her thrombocytopenia and anemia worsened. SLE was diagnosed on postoperative day 5 by a comprehensive autoimmune workup. She was discharged on postoperative day 34 with remission. Conclusion Our case and previous reports suggest that distinguishing underlying SLE from preeclampsia in the third trimester is particularly difficult. Helpful factors for diagnosis of suspected SLE in these cases were persistence of symptoms and new atypical symptoms for preeclampsia revealed after delivery (e.g., fever, renal disorder, and thrombocytopenia).

Abstract
BACKGROUND AND PURPOSE Experiences with computer-assisted detection of cerebral aneurysms in diagnosis by radiologists in real-life clinical environments have not been reported. The purpose of this study was to evaluate the usefulness of computer-assisted detection in a routine reading environment. MATERIALS AND METHODS During 39 months in a routine clinical practice environment, 2701 MR angiograms were each read by 2 radiologists by using a computer-assisted detection system. Initial interpretation was independently made without using the detection system, followed by a possible alteration of diagnosis after referring to the lesion candidate output from the system. We used the final consensus of the 2 radiologists as the reference standard. The sensitivity and specificity of radiologists before and after seeing the lesion candidates were evaluated by aneurysm- and patient-based analyses. RESULTS The use of the computer-assisted detection system increased the number of detected aneurysms by 9.3% (from 258 to 282). Aneurysm-based analysis revealed that the apparent sensitivity of the radiologists' diagnoses made without and with the detection system was 64% and 69%, respectively. The detection system presented 82% of the aneurysms. The detection system more frequently benefited radiologists than being detrimental. CONCLUSIONS Routine integration of computer-assisted detection with MR angiography for cerebral aneurysms is feasible, and radiologists can detect a number of additional cerebral aneurysms by using the detection system without a substantial decrease in their specificity. The low confidence of radiologists in the system may limit its usefulness.

Abstract
Abstract
Background: It is not known which population of estrogen receptor (ER)-positive breast cancer patients should continue endocrine treatment beyond 5 years to overcome late recurrences. The aim of this study was to examine a combination of nuclear grade (NG) and expression level of ER and progesterone receptor (PR) to predict late recurrences.
Methods: We assessed retrospectively 1677 consecutive ER-positive/HER2-negative patients who underwent surgical resection between 2004 and 2009. Patients with T2 or larger tumor and/or node-positive received pre- or postoperative chemotherapy following the international consensus panel from the St Gallen Conference, 2003. All patients had received adjuvant endocrine treatment. NG, ER and PR statuses were determined by immunohistochemistory on surgical specimen. We classified the patients into 3 groups as follows; ER-high (+++ or Allred score 7, 8)/PR-high (++ to +++ or 5-8) (n=212), ER-high / PR-low (- to + or 3-6) (n=208), and ER-low (+ to ++ or 3-6) / PR-any (n=255). We compared distant disease-free survival (DDFS) in each cohort based on the NG (1:low, and 2 or 3: high).
Results: A median follow-up period was 77.0 months. Four hundred sixty seven patients (27.8%) received neoadjuvant chemotherapy, 208 patients (12.4%) received adjuvant chemotherapy, and 1002 patients (59.8%) did not received chemotherapy. Of the 467 patients with neoadjuvant chemotherapy, 65 patients (13.9%) had developed distant metastasis during study period (before 5 years in 51 (11.0%); and after 5 years in 14 (3.0%)). NG-low had significantly higher risk of late recurrence after 5 years than that of NG-high (p=0.005). According to hormonal receptor expression levels, in patients with NG-low, ER-low/PR-any had significantly higher overall DDFS rate than ER-high/PR-low (p=0.016). A similar trend was found before 5 years (p=0.077). However, ER-high/PR-high turned to have significantly high risk of recurrence after 5 years compared to ER-low/PR-any (p=0.024). Of the 208 patients with adjuvant chemotherapy, 16 patients (7.6%) had developed distant metastasis during study period (before 5 years in 5 (2.4%), and after 5 years in 11 (5.2%)). there was no association between a risk of recurrence and hormone receptor statuses at any study period. In the patients did not received chemotherapy, ER-high/PR-high had a trend of higher DDFS rate than others before 5 years (p=0.067). Of the 1002 patients without chemotherapy, only 36 patients (3.6%) had developed distant metastasis during study period (before 5 years in 27 (2.7%), and after 5 years in 9 (0.9%)). There was no difference of late recurrence after 5 years among the patients regardless of ER and PR expression level and NG with only low recurrence rate (0.9%).
Conclusions: Our results demonstrated that, in ER-positive/HER2-negative patients who underwent neoadjuvant chemotherapy, NG-low/ER-high/PR-high should receive extend hormonal treatment over 5 years because of the high risk of late recurrence but NG-high/ER-high might not need. Furthermore, patients with T1 and node-negative may not need extend hormonal treatment because of the extremely low risk of late recurrence regardless of NG and hormone receptor statuses.

Abstract
Abstract
Background:
In patients with estrogen receptor (ER)-positive advanced breast cancer, everolimus plus exemestane prolongs progression-free survival compared to exemestane monotherapy. However, as an adverse event from everolimus, oral mucositis (all grades) has been reported in 58% of all patients and 81% of Asian patients. Although no established prevention method is available, a previous study reported that professional oral care might prevent oral mucositis, and dentists have hypothesized that such care can reduce the occurrence of oral mucositis induced by everolimus. To evaluate this hypothesis, we compare the incidence of oral mucositis with and without professional oral care.
Method:
This is a randomized, multi-center, open-label, phase III study to evaluate the efficacy of professional oral care in preventing oral mucositis induced by everolimus in postmenopausal ER-positive metastatic breast cancer (MBC). Patients will be randomized into professional oral care and control groups (1:1 ratio). All patients will receive everolimus (10 mg daily) with exemestane (25 mg daily) and will continue everolimus until disease progression. Before the initiation of everolimus, instruction on a professional brushing method will be provided to both groups by specialists. In the professional oral care group, patients will receive teeth surface cleaning, scaling, and tongue cleaning before starting everolimus, and will continue to receive professional oral care weekly from oral surgeons throughout the 8 week treatment. In the control group, patients will brush their own teeth and gargle with 0.9% sodium chloride solution or water. The primary endpoint is the incidence of all grades of oral mucositis. The secondary endpoints are the incidence of over grade 2 and over 3 oral mucositis as determined by an oncologist and oral surgeons. The endpoints include onset and duration of oral mucositis. Major eligibility criteria include: 1) Postmenopausal women with ER positive MBC, and 2) No more than one prior chemotherapy treatment for MBC. Target accrual is 200 patients with a two-sided type I error rate of 5% and 80% power to detect 25% risk reduction. This study has just begun, and 5 of a planned 200 patients have been enrolled. (This study was registered with the UMIN 000016109).

Abstract
Abstract
Background: Triple-negative breast cancers (TNBC) are defined as tumors that lack expression of estrogen receptor (ER), progesterone receptor (PR), and HER2. TNBC is characterized as a cancer with a high malignancy potential and a poor prognosis. Systemic therapy that is effective in TNBC is only chemotherapy. On magnetic resonance imaging (MRI), rim enhancement was frequently seen in TNBC. It is reported that rim enhancement on MRI may associated with long-term outcome of patients with triple-negative breast cancer and may potentially serve as a prognostic biomarker in these patients. It is not well known about the relationship of rim enhancement on the MRI and treatment effectiveness of TNBC.
Purpose: We investigated the relationship between rim enhancement on MRI and response of chemo therapy and outcome in patients with TNBC.
Methods: MRI findings of 144 consecutive female TNBC patients, who underwent surgery from 2007 to 2012 in our hospital, were retrospectively reviewed. All patients have taken the MRI in our hospital before treatment, and had undergone chemotherapy before or after surgery. Presence of rim enhancement on MRI was assessed. Rim enhancement was defined more pronounced at the periphery of the mass at early phase.
Association of the presence of rim enhancement on MRI and the pathological complete response (pCR) rate in patients who underwent neo adjuvant chemotherapy (NAC) was assessed using two-sided Pearson's Chi squared tests. Disease free survival (DFS) rates were calculated by the Kaplan-Meier method. Univariate analysis was performed using the log rank test. pCR was defined as the disappearance of invasive cancer.
Results: The median age was 51yo (26-82), and the median observation period was 49 months (5-92). Eighty-one patients (56.2%) underwent NAC and 63 patients (43.7%) underwent adjuvant chemotherapy. Twenty-six cases (18.0%) occurred recurrence or distance metastasis. The presence of rim enhancement were observed 68 cases (42.3%), and non-rim enhancement were 66 cases (57.6%). DFS were not significantly different according to the presence of rim enhancement on MRI(P=0.31).
In NAC patients, 28 patients (34.5%) were led to pCR and 53 (63.4%) were non-pCR. The presence of rim enhancement were observed 44 cases (54.3%), and non-rim enhancement were 37 cases (45.6%). In pCR rate, rim enhancement is higher than non-rim enhancement (40.9%, 27.0%, respectivrly). However, the presence of rim enhancement on MRI was not significantly associated with pCR in TNBC patients (p= 0.190).

Abstract
Forkhead box O (Foxo) transcription factors may be involved in the salutary effect of dietary restriction (DR). This study examined the role of Foxo3 in lifespan extension and cancer suppression in DR mice. Wild-type (WT) and Foxo3-knockout heterozygous (+/–) and homozygous (–/–) mice were subjected to a 30% DR regimen initiated at 12 weeks of age. Control mice were fed ad libitum (AL) throughout the study. In contrast to WT mice, DR did not significantly extend the lifespan of Foxo3+/– or Foxo3–/– mice. However, DR reduced the prevalence of tumors at death in WT, Foxo3+/–, and Foxo3–/– mice. These results indicate the necessity of Foxo3 for lifespan extension but not cancer suppression by DR. The findings in Foxo3+/– mice contrast with those in Foxo1+/– mice reported previously by our laboratory suggest differential regulation of cancer and lifespan by DR via Foxo1 and Foxo3.
