| Abstract | To compare the health-related quality of life of elderly patients after radical cystectomy for bladder cancer in urinary diversion groups: ileal conduit, ureterocutaneostomy, or orthotopic urinary reservoir. The 109 participating elderly patients aged 75 or older completed self-reporting questionnaires: the QLQ-C30, and on satisfaction with urinary diversion methods. Fifty-six patients had undergone constructions for ileal conduit diversion, 31 for ureterocutaneostomy, and 22 for orthotopic urinary reservoir (OUR). The median follow-up period for each group was 4.0 years (range 0.3-11.2), 4.5 years (range 0.3-18.0), and 3.3 years (range 0.3-6.7), respectively. Regardless of the type of urinary diversion, the majority of patients reported having good overall quality of life, although with some problem of pain. No significant differences among urinary diversion subgroups were found in any quality of life area in the QLQ-C30 questionnaire. More patients in the OUR sub-group felt disappointment than those in the ileal conduit or cutaneostomy sub-groups. However, a questionnaire which asked which diversion method would be preferable showed a trend that more patients in the OUR subgroup would have chosen the same one. Health-related quality of life appeared relatively good in these 3 groups. Patient demands and expectations may be so different from the results that the details of each urinary diversion method should be explained thoroughly. OUR construction could be a candidate even for elderly patients. |

| Abstract | We report 4 cases of surgical resection of metachronous lymph node (LN) metastases from hepatocellular carcinoma (HCC) following hepatectomy. Clinicopathological features and results of LN dissection were investigated in the 4 patients. One patient was found to have a single metastasis in the mediastinal LNs, another had multiple metastases in the mediastinal and abdominal LNs, and the other 2 had single metastases in the abdominal LN. The locations of the abdominal LN metastases were behind the pancreas head in 2 patients and around the abdominal aorta in 1 patient. They all underwent surgical resection of metastatic LNs and had no postoperative complications. The 3 patients whose LN metastases were solitary have been alive for more than 2 years after LN resection, and one of them is free from recurrence. The patient with multiple LN metastases died 13 months after LN resection due to carcinomatosis. With the expectation of long-term survival, a single metachronous LN metastasis from HCC after hepatectomy should be resected in patients without uncontrollable intrahepatic or extrahepatic tumors. |

| Abstract | Preeclampsia may be due to an excess of circulating anti-angiogenic growth factors derived from the placenta, but metabolic syndrome-like disorders may also set off a cascade of placental and systemic inflammation and oxidative stress. We present a case of severe superimposed preeclampsia with obesity, diabetes and a mild imbalance of angiogenic factors, in which diet therapy ameliorated the preeclamptic signs while improving the adiponectin level. A 41-year-old pregnant woman with obesity and diabetes was referred to our hospital because of severe proteinuria and hypertension at 22 weeks of gestation. After administration of insulin and hydralazine with diet therapy, her hypertension and proteinuria were ameliorated with a 15-kg weight loss. Her adiponectin level was low and her leptin level was high, but her angiogenic factor levels were within the normal ranges for pregnant women at admission. The diet therapy ameliorated her hypertension and proteinuria while improving her adiponectin level as she achieved weight loss. This case suggests that diet therapy for obese preeclampsia patients with a mild imbalance of anti-and pro-angiogenic factors may play an important role in managing preeclampsia. Measurements of maternal adipocytokines and angiogenic factors may be important to distinguish the main cause of preeclampsia, i.e., poor placentation or maternal constitutional factors, for managing preeclampsia in patients with obesity. |

| Abstract | Several international studies have suggested that treatment of early Parkinsonʼs disease (PD) with a dopamine agonist instead of levodopa delays the occurrence of motor complications. This 5-year prospective, open, multicenter randomized study aimed to compare the effects of cabergoline on the onset of motor complications with those of levodopa in Japanese patients with early PD. Patients who had never been treated with dopamine agonists or levodopa were enrolled in this study. Four of 45 patients in the cabergoline group and 11 of 46 patients in the levodopa group developed motor complications. The estimated cumulative incidence of motor complications in the cabergoline and levodopa groups was 17ｵ and 34ｵ (hazard ratio, 0.57;95ｵ confidence interval, 0.18‒1.81;p＝0.347). Thirty-five adverse events (AEs) were reported in 24 patients in the cabergoline group, while 16 AEs were reported in 13 patients in the levodopa group. Patients in the cabergoline group showed fewer motor complications than did those in the levodopa group, although the difference was not statistically significant. However, the hazard ratio found in this study was similar to those in previous reports. |

| Abstract | A new hemispherical electrode to heat oral cavity cancer is proposed. The electrode does not produce a hot spot around its edge, a feature that usually arises when using radio frequency (RF) capacitive-type heating. The hemispherical electrode was designed by computer simulation using a 3-D finite element method. To assess its practicality and effectiveness, we built a prototype hemispherical electrode and evaluated its heating characteristics by phantom experiments. The heating effects on the phantom were measured by thermography. The concave phantom surface in contact with the hemispherical electrode showed a uniform increase in temperature, with no obvious edge effect. The proposed electrode allows non-invasive RF capacitive-type heating for intracavity tumors that was not previously considered possible, and should contribute to the multidisciplinary treatment of intracavity tumors. |

| Abstract | Recent studies have demonstrated the important role of immune molecules in the development of neuronal circuitry and synaptic plasticity. We have detected the presence of FcγRllB protein in parvalbumin- containing inhibitory interneurons (PV neurons). In the present study, we examined the appearance of PV neurons in the barrel cortex and the effect of sensory deprivation in FcγRllB-deficient mice (FcγRllB-/-) and wild-type mice. There was no substantial difference in the appearance of PV neurons in the developing barrel cortex between FcγRllB-/- and wild-type mice. Sensory deprivation from immediately after birth (P0) or P7 to P12-P14 induced an increase in PV neurons. In contrast, sensory deprivation from P7 or P14 to P28, but not from P21 to P28, decreased PV neurons in wild-type mice. However, sensory deprivation from P0 or P7 to P12-P14 did not increase PV neurons and sensory deprivation from P7 or P14 to P28 did not decrease or only modestly decreased PV neurons in FcγRllB-/- mice. The results indicate that expression of PV is regulated by sensory experience and the second and third postnatal weeks are a sensitive period for sensory deprivation, and suggest that FcγRllB contributes to sensory experience-regulated expression of PV. |

| Abstract | Patients with hepatocellular carcinoma (HCC) complicated by portal vein tumor thrombus (PVTT) have an extremely poor prognosis. It is important to select adequate therapeutic options based on reliable prognostic factors using imaging studies and clinical data. Prognostic factors were analyzed in patients with HCC with PVTT in the first branch or main trunk of the portal vein. From 2000 to 2007, 107 consecutive patients with HCC with PVTT in the major portal vein were reviewed, and diagnostic images and clinical characteristics were retrospectively observed. Thirty-eight possible prognostic factors for survival were analyzed by the log-rank test and multivariate analysis using Coxʼs proportional hazards model. Median overall survival was 14 months following PVTT diagnosis. Survival rates at 6 months, 1, 2, and 3 years were 72.1%, 52.6%, 32.6%, and 29.6%, respectively. Independent prognostic factors for longer survival included:patient age ＜65 years, Child-Pugh classification A/B, PVTT treatment, accumulation of Lipiodol in the PVTT after TACE, initial radical treatment for HCC, HCC located in a single lobe of the liver, and no invasion of HCC to the hepatic vein or bile duct. Survival was associated with liver function, tumor extension, and treatment for HCC and PVTT. |

| Abstract | Human lymphoblastoid TK6 and WTK-1 cells are widely used to detect mutagens in vitro. TK6 cells have wild-type TP53 alleles, while WTK-1 cells have one allele of mutated TP53. Both cells were treated with 5-fluorouracil (5-FU), and gene mutation assay and micronucleus assay were performed to clarify the differential response related to the TP53 gene status. The effects of 5-FU on gene expression were assessed by microarray and quantitative RT-PCR analyses. In WTK-1 cells, 5-FU increased the frequency of cells with micronucleus and mutation. In TK6 cells, frequency of cells with micronucleus was increased but the mutation frequency was not. The cytotoxicity induced by 5-FU was more prominent in TK6 cells than in WTK-1 cells. Analysis of gene expression showed that the genes involved in the TP53 pathway were up-regulated in TK6 cells but not in WTK-1 cells. The differential responses to 5-FU between these cell lines appeared to be due to the difference in the TP53 gene status, thus providing a molecular basis for the bioassays using these cell lines in the toxicology field. Our results indicate that the clinical efficacy of 5-FU chemotherapy may depend on the TP53 genotype. |

| Abstract | We studied the effects of natural essential oil on neurite outgrowth in PC12m3 neuronal cells to elucidate the mechanism underlying the action of the oils used in aromatherapy. Neurite outgrowth can be induced by nerve growth factor (NGF), where ERK and p38 MAPK among MAPK pathways play important roles in activating intracellular signal transduction. In this study, we investigated whether d-limonene, the major component of essential oils from oranges, can promote neurite outgrowth in PC12m3 cells, in which neurite outgrowth can be induced by various physical stimulations. We also examined by which pathways, the ERK, p38 MAPK or JNK pathway, d-limonene acts on PC12m3 cells. Our results showed that neurite outgrowth can be induced when the cells are treated with d-limonene. After treatment with d-limonene, we observed that p38 MAPK is strongly activated in PC12m3 cells, while ERK is weakly activated. In contrast, JNK shows little activity. A study using an inhibitor of p38 MAPK revealed that neurite outgrowth in PC12m3 cells is induced via the activation of p38 MAPK by d-limonene. The results thus indicate that d-limonene may promote neural cell differentiation mainly via activation of the p38 MAPK pathway. |

| Abstract | To clarify surgical outcomes for 5 ophthalmic diseases in terms of vision-related quality of life (QOL), we sent a self-administered Visual Function Questionnaire-14 (VF-14) to patients 3 months postoperatively, and the VF-14 scores for the surgical outcome of strabismus were compared with those of patients with diabetic macular edema (DME), cataract, glaucoma, and epiretinal membrane (ERM). Test-retest repeatability of VF-14 was evaluated with Bland-Altman analysis. Of the 625 eligible patients who were referred for enrollment, 48 with comitant strabismus, 50 with incomitant strabismus, 45 with DME, 38 with cataract, 129 with glaucoma, and 73 with ERM agreed to answer. Eighty percent of subjects showed 95ｵ limits of agreement with the VF-14 evaluated by repeated measurements. The gain by surgery for incomitant strabismus was not different from that of cataract (p＝0.5551), but it was significantly better than those of DME (p＝0.0266), comitant strabismus (p＝0.0128), ERM (p＝0.0021), glaucoma with cataract (p＜0.0001), and glaucoma alone (p＜0.0001). The surgical outcome in terms of QOL for patients with incomitant strabismus was good and comparable to that of patients with cataract surgery. |

| Abstract | Although a number of studies have investigated the relationship of sleep duration to overweight and obesity, studies conducted among population-based elementary schoolchildren have been limited in Japan. The aim of the present study was to investigate the relationship between sleep duration and overweight among elementary schoolchildren in Japan. The study subjects were all fourth-grade schoolchildren (9 or 10 years of age) in Ina-town, Saitama Prefecture, Japan from 1999 to 2008. Information concerning each subjectʼs sex, age, and lifestyle was obtained using a self-administered questionnaire, while measurements of his or her height and weight were carried out. Childhood overweight was determined according to the definition established by the International Obesity Task Force. Data from 3,433 children were analyzed. In logistic regression analysis, a statistically significant dose-response relationship was observed between sleep duration and overweight among boys (p for trend＝0.014) but not among girls (p for trend＝0.149). Short sleep duration was associated with childhood overweight, and the sex difference in the association was observed. These findings suggested that it is important to consider sleep duration as part of any program to prevent overweight among elementary schoolchildren, especially among boys. |

| Abstract | Radiotherapy plays a central part in cancer treatment, and use of radiosensitizing agents can greatly enhance this modality. Although studies have shown that several chemotherapeutic agents have the potential to increase the radiosensitivity of tumor cells, investigators have also studied a number of molecularly targeted agents as radiosensitizers in clinical trials based on reasonably promising preclinical data. Recent intense research into the DNA damage-signaling pathway revealed that ataxia-telangiectasia mutated (ATM) and the Mre11-Rad50-NBS1 (MRN) complex play central roles in DNA repair and cell cycle checkpoints and that these molecules are promising targets for radiosensitization. Researchers recently developed three ATM inhibitors (KU-55933, CGK733, and CP466722) and an MRN complex inhibitor (mirin) and showed that they have great potential as radiosensitizers of tumors in preclinical studies. Additionally, we showed that a telomerase-dependent oncolytic adenovirus that we developed (OBP-301 [telomelysin]) produces profound radiosensitizing effects by inhibiting the MRN complex via the adenoviral E1B55kDa protein. A recent Phase I trial in the United States determined that telomelysin was safe and well tolerated in humans, and this agent is about to be tested in combination with radiotherapy in a clinical trial based on intriguing preclinical data demonstrating that telomelysin and ionizing radiation can potentiate each other. In this review, we highlight the great potential of ATM and MRN complex inhibitors, including telomelysin, as radiosensitizing agents. |

| Abstract | Many authors have reported on iatrogenic vertebral artery (VA) injury, but, to our knowledge, this is the first report of a dominant VA injury with compensatory blood flow from the hypoplastic VA. A 23-year-old woman with juvenile rheumatoid arthritis and atlantoaxial subluxation sustained injury to her dominant VA after occipitocervical fusion using transarticular screws. This did not result in lethal consequences due to compensation from her hypoplastic contralateral VA. Postoperative angiography, however, illustrated occlusion of the dominant left side, while the hypoplastic VA of the right side was enlarged. The patient experienced vertigo and loss of consciousness several times during rehabilitation. At the 4-year follow-up exam, bony fusion was observed, with no neurological deficits or correction loss. She had had no episodes of unconsciousness and no recurrence of any symptoms over the previous 3 years. |

| Abstract | We report a 38-year old man with a giant-cell tumor in a rare site, the patella. Primary patellar neoplasms are highly unusual. According to a survey by the Bone and Soft Tissue Tumor Committee of the Japanese Orthopaedic Association, of more than 2,126 giant-cell tumors of bone reported since 1972, only 22 were primary patellar neoplasms. We present a case of this rare entity along with its clinical and radiographic features. The first clinical symptom was anterior knee pain. Though anterior knee pain has numerous and varied causes, it is necessary to consider patellar bone tumors in the differential diagnosis. |

| Abstract | This study investigated the appropriate tourniquet pressure (TP) and duration of tourniquet application for venipuncture by calculating the venous cross-section (VCS) area on ultrasonography. Twenty healthy volunteers without cardiovascular risk factors were enrolled in this study. A target vein (either a cephalic or median cubital vein) was selected on ultrasonography. The pneumatic tourniquet was inflated using a rapid cuff inflator system at setting pressure for 120sec. TP strength was varied from 20mmHg to 100mmHg, in 20mmHg increments. The order of TP was randomized. Compari-sons among more than 3 groups were performed by one-way repeated-measures ANOVA and the Bonferroni method. The VCS area increased rapidly until 10sec after tourniquet inflation. The VCS area then increased gradually until 30sec after tourniquet inflation. After that, the VCS area did not increase remarkably. The VCS area increased with TP strength up to 80mmHg, but the VCS area at TP 100mmHg decreased to less than that at TP 40mmHg. Based on these results, we recommend a tourniquet pressure of 60mmHg, and duration of tourniquet application is 30 to 60sec for venipuncture. |

| Abstract | Percutaneously inserted central catheters (PICCs) are often used in neonatal medicine. Venous thrombosis (VT) is one of the complications associated with PICC use. According to some reports, fresh frozen plasma (FFP) may be a risk factor for VT. The purpose of this study was to determine whether FFP use is associated with VT in extremely low birth weight infants (ELBWIs). We performed a matched case-control study on risk factors for VT in ELBWIs born over a period of 5 years in the neonatal intensive care unit of a tertiary hospital. Controls were infants from the unit matched for gestational age and birth weight. We performed univariate analyses and created receiver operating characteristic (ROC) curves for the cut-off values of continuous parameters such as FFP. We also conducted multivariate conditional logistic regression analysis and calculated adjusted odds ratios and their 95% confidence intervals. Thirteen VT cases and 34 matched controls were examined. Using an ROC curve, FFP by day 5＞50mL/kg was selected as the cut-off value. In multivariate conditional logistic regression analysis, FFP by day 5＞50mL/kg exhibited an adjusted odds ratio of 5.88 (95% confidence interval:1.12-41.81, p＝0.036). FFP by day 5＞50mL/kg may be a risk factor for VT in ELBWIs. |

| Abstract | The purpose of this study was to evaluate prognostic factors for epithelial ovarian cancer. We found that the pretreatment values of maximum standardized uptake (SUVmax) of the primary tumor by positron emission tomography/computed tomography (PET/CT), tumor marker CA125 and C-reactive protein (CRP) were correlated with clinical characteristics and prognosis for such patients. The clinical parameters and prognoses and their correlations with SUVmax of primary tumor, CA125 and CRP were examined for 51 patients with primary ovarian cancer. The SUVmax of the primary tumor had a statistically significant association with stage (p＝0.010) and histology (p＝0.001). CA125 was significant associated with stage (p＝0.011), histology (p＝0.005) and lymph node metastasis (p＝0.025). CRP was also significantly associated with stage (p＝0.049). Disease-free survival rates of patients exhibiting a high SUVmax, CA125 and CRP were significantly lower than those exhibiting a low SUVmax, CA125 and CRP levels (p＝0.008, 0.034, and 0.037, respectively). Furthermore, overall survival rates of patients exhibiting a high SUVmax were significantly lower than those exhibiting a low SUVmax (p＝0.049).The high SUVmax of primary tumor is an important factor for identifying ovarian cancer patients with a predictor for poor prognosis. |

| Abstract | Little research has been done on the association between relaxation and health. In the present study, by conducting a nationwide cross-sectional survey, we aimed to obtain scientific data on the preferable forms of relaxation for health promotion, and to clarify the associations between specific recreational activities and self-perceived mental and physical health. We selected 4,000 households by stratified random sampling from across Japan in November 2009 and used the interview method to collect data (number of subjects:2,206). The questionnaire contained items on sleep, recreation status, recreational activities, and self-perceived mental and physical health status. We obtained responses from 1,224 adults (response rate:55.5%). Insufficient rest from sleep, short sleep duration (＜6h/day), ineffective use of free time, and less free time used for activities other than rest showed independent positive associations with poor mental and physical health. The results of the logistic regression analyses showed significantly low adjusted odds ratios with regard to the status of poor mental and physical health for outings/walking among men (0.33 [95% confidence interval;0.16-0.68] and 0.49 [0.26-0.90], respectively), and for community activities among women (0.19 [0.04-0.79] and 0.27 [0.09-0.77], respectively). Relaxation for the promotion of health should include both passive relaxation (rest) and active relaxation (recreation). In addition, ensuring sufficient sleep duration is important for passive relaxation, and engaging in outings/walking for men and community activities for women are important for active relaxation. |

| Abstract | To quantify gait bradykinesia during daily activity in patients with Parkinson's disease (PD), we measured movement-induced accelerations over more than 24h in 50 patients with PD and 17 age-matched normal controls, using a new device, the portable gait rhythmogram. Acceleration values induced by various movements, averaged each 10 min, exhibited a gamma distribution. The mean value of the distribution curve was used as an index of the "amount of overall movement per 24h". Characteristic changes were observed in both the gait cycle and gait acceleration. During hypokinesia, the gait cycle became either faster or slower. A number of patients with marked akinesia/bradykinesia showed a reduced and narrow range of gait acceleration, i.e., a range of floor reaction forces. The results suggest that assessment of the combination of changes in gait cycle and gait acceleration can quantitatively define the severity of gait bradykinesia. |

| Abstract | Polypropylene mesh implants for the correction of pelvic organ prolapse (POP) are now available in Japan. We developed an innovative approach for correcting POP by placing polypropylene mesh transvaginally with laparoscopic assistance. From June 2007 through March 2010, sixteen consecutive patients with symptomatic stage 2 or 3 pelvic organ prolapse underwent the laparoscopic-assisted tension-free vaginal mesh procedure at Okayama University Hospital. All patients were evaluated before and at 1, 3, 6, and 12 months after surgery. Female sexual function was also evaluated with the Female Sexual Function Index (FSFI). The procedure was performed successfully without significant complications. Fifteen of 16 patients were considered anatomically cured (93.8%) at 12 months postoperatively. One patient with a recurrent stage 3 vaginal vault prolapse required sacral colpopexy six months postoperatively. Total FSFI scores improved significantly from 10.3±1.3 at baseline to 18.0±1.2 at 12 months after surgery. The laparoscopic-assisted trans-vaginal mesh is a safe, effective, and simple procedure for POP repairs. The procedure not only restores anatomic relationships but also improves sexual function. |
