Abstract
BACKGROUND To examine the effect of the histology of carcinoma and sarcoma components on survival outcome of uterine carcinosarcoma. PATIENTS AND METHODS A multicenter retrospective study was conducted to examine uterine carcinosarcoma cases that underwent primary surgical staging. Archived slides were examined and histologic patterns were grouped based on carcinoma (low-grade versus high-grade) and sarcoma (homologous versus heterologous) components, correlating to clinico-pathological demographics and outcomes. RESULTS Among 1192 cases identified, 906 cases were evaluated for histologic patterns (carcinoma/sarcoma) with high-grade/homologous (40.8%) being the most common type followed by high-grade/heterologous (30.9%), low-grade/homologous (18.0%), and low-grade/heterologous (10.3%). On multivariate analysis, high-grade/heterologous (5-year rate, 34.0%, P = 0.024) and high-grade/homologous (45.8%, P = 0.017) but not low-grade/heterologous (50.6%, P = 0.089) were independently associated with decreased progression-free survival (PFS) compared with low-grade/homologous (60.3%). In addition, older age, residual disease at surgery, large tumor, sarcoma dominance, deep myometrial invasion, lymphovascular space invasion, and advanced-stage disease were independently associated with decreased PFS (all, P < 0.01). Both postoperative chemotherapy (5-year rates, 48.6% versus 39.0%, P < 0.001) and radiotherapy (50.1% versus 44.1%, P = 0.007) were significantly associated with improved PFS in univariate analysis. However, on multivariate analysis, only postoperative chemotherapy remained an independent predictor for improved PFS [hazard ratio (HR) 0.34, 95% confidence interval (CI) 0.27-0.43, P < 0.001]. On univariate analysis, significant treatment benefits for PFS were seen with ifosfamide for low-grade carcinoma (82.0% versus 49.8%, P = 0.001), platinum for high-grade carcinoma (46.9% versus 32.4%, P = 0.034) and homologous sarcoma (53.1% versus 38.2%, P = 0.017), and anthracycline for heterologous sarcoma (66.2% versus 39.3%, P = 0.005). Conversely, platinum, taxane, and anthracycline for low-grade carcinoma, and anthracycline for homologous sarcoma had no effect on PFS compared with non-chemotherapy group (all, P > 0.05). On multivariate analysis, ifosfamide for low-grade/homologous (HR 0.21, 95% CI 0.07-0.63, P = 0.005), platinum for high-grade/homologous (HR 0.36, 95% CI 0.22-0.60, P < 0.001), and anthracycline for high-grade/heterologous (HR 0.30, 95% CI 0.14-0.62, P = 0.001) remained independent predictors for improved PFS. Analyses of 1096 metastatic sites showed that carcinoma components tended to spread lymphatically, while sarcoma components tended to spread loco-regionally (P < 0.001). CONCLUSION Characterization of histologic pattern provides valuable information in the management of uterine carcinosarcoma.

Abstract
BACKGROUND The influence of adenomyomectomy on subsequent pregnancy is unknown. Placenta accreta is most often associated with placenta previa in women with multiple previous cesarean sections. CASE A 41-year-old woman became pregnant six years after a laparoscopic uterine posterior adenomyomectomy. She was diagnosed with complete placenta previa and considered at a low risk for placenta accreta by ultrasonography. Cesarean section and subsequent hysterectomy were required, and histopathological analysis revealed a posterior placenta accreta. DISCUSSION The authors discuss the association of adenomyomectomy and placenta accreta on subsequent pregnancy and conclude that previous adenomyomectomy may increase the risk of abnormal placentation. Therefore, careful treatment is required during the pregnancies of patients with previous adenomyomectomy.

Abstract
PURPOSE To present a case report on the successful management of a low-lying placenta and aplastic anemia. Aplastic anemia is a rare but serious disorder that is often characterized by severe pancytopenia. Because of the rarity of aplastic anemia, a pregnancy complicated by it is rarely encountered by obstetricians. Moreover, placenta previa (low-lying placenta) complicated by aplastic anemia has not been previously reported. MATERIALS AND METHODS The authors present the first reported case of placenta previa with aplastic anemia in a patient who had undergone a previous cesarean delivery. RESULTS They successfully managed this case by making a transverse uterine fundal incision during an elective cesarean delivery. This incision minimized blood loss and enabled good visualization of the source of bleeding in the lower uterine segment. Bleeding was stemmed by suturing the source of bleeding. CONCLUSION The authors propose that this procedure should be considered for patients with low platelet counts and abnormal placentation.

Abstract
The correlation between the amount of lipid peroxide and squalene in skin surface lipid was observed by statistical analysis. To investigate the mechanism of skin surface lipid peroxidation, especially the role of active oxygen, squalene was irradiated by long wavelength ultraviolet light (UVA) with or without the photosensitizer, 8-methoxypsoralen (8MOP). Sodium azide (NaN3), a singlet oxygen quencher, or deuterium oxide, which elongates the life time of singlet oxygen, were also added in these experiments. The lipid peroxidation was detectable by observing malondialdehyde (MDA) formation. The MDA value in squalene solution was increased by UVA irradiation, and this effect was enhanced under the presence of 8MOP. These effects were repressed by the addition of NaN3 in the experimental system. These results may show that squalene peroxidation was mediated by singlet oxygen. Epidermal keratin could inhibit the increase of MDA values in human skin surface lipid in vitro. The inhibitory effect of epidermal protein on the deposition or the formation of lipid peroxide in skin surface was suggested.

Abstract
Lipid peroxide in human skin surface lipids was investigated. The correlation between the amount of lipid peroxide and the total amount of lipids in skin surface lipids was determined by statistical analysis. Furthermore, the correlation between lipid peroxide and squalene in skin surface lipids was also proved. These results suggest that the major source of lipid peroxide in skin surface is squalene, and that lipid peroxidation is enhanced by external factors such as ultraviolet light irradiation.

Abstract
It is important to determine the immunological properties for the maintenance of health. We chose the Shikoku Walking Pilgrimage to assess the proper biomarkers for the evaluation of immunological properties. We examined whether the Shikoku Walking Pilgrimage could have a positive effect on the mental and physical health of walking participants by using several biomarkers proposed by our laboratory. Twelve non-randomized healthy male volunteers including 3 twice attendees walked the Shikoku Walking Pilgrimage distance of 58.9 km over 3 days. Plasma, serum, urine, and saliva were collected from the volunteers during the pilgrimage and at 1 week before and after it. Immunological biomarkers, including lipid metabolism, oxidative stress, immune function, and catecholamines, were measured. Additionally, mood state scores, alertness, autonomic nervous system activity, and body motion levels during sleep were assessed. A significant decrease was observed in the subjective tension-anxiety levels and in the concentrations of serum low-density lipoprotein cholesterol, plasma hydroxyoctadecadienoic acid (HODE), and urine adrenaline during the pilgrimage as compared to the values of these parameters before the participants embarked on the pilgrimage. The serum levels of brain-derived neurotrophic factor (BDNF) were significantly increased 1 week after the pilgrimage relative to those assessed previously. No significant differences in subjective fatigue and the flicker perception threshold were observed. These results suggest that the Shikoku Walking Pilgrimage can exert a positive effect on mental and physical health as particularly shown in the reduction of tensionanxiety and oxidative stress without the accompaniment of fatigue. HODE correlated significantly with typical immunological marker natural killer cell activity and immunoglobulin G. This suggests that there are promising biomarkers such as HODE, NK activity, BDNF, LDL-c, and IgG for assessing the immunological properties.

Abstract
Identification of reliable markers of radiosensitivity and the key molecules that donate susceptibility to anticancer treatments to esophageal cancer cells would be highly desirable. We found that the mRNA expression of insulin-like growth factor 2 mRNA-binding protein 3 (IGF2BP3) was higher in radioresistant TE-5 and TE-9 cells than in radiosensitive TE-12 cloneA1 cells. Conversely, knocking down expression of IGF2BP3 mRNA in TE-5 and TE-9 cells using small interfering RNA significantly enhanced their radiosensitivity. Furthermore, patients with squamous cell esophageal cancers strongly expressing IGF2BP3 tended to respond poorly to chemoradiation. These data suggest that IGF2BP3 may be a key marker of radiosensitivity that diminishes the susceptibility of squamous cell esophageal cancer cells to radiotherapy. IGF2BP3 may, thus, be a useful target for improving radiotherapy for patients with esophageal squamous cell carcinoma.

Abstract
Esophageal squamous cell cancer (ESCC) is a high-grade carcinoma that is treated with multidisciplinary approaches, including chemoradiotherapy (CRT) followed by surgery. Despite some success with these therapies, overall survival remains poor. In order to investigate a newer CRT regimen, we designed a comparative study to evaluate preoperative CRT using docetaxel (DOC) or 5-Fluorouracil and cisplatin (FU+CDDP [FP] therapy) for treatment of resectable ESCC. In a retrospective review of patients with resectable, locally advanced ESCC, 95 patients received preoperative CRT between 2001 and 2007. CRT was administered using either FP (n = 40) or DOC (n = 55). Pathological response and clinical outcomes were compared between the two groups. Hazard ratios and time-to-event analyses were used to assess outcomes; the ratios were controlled by multivariate logistic regression analysis of potential prognostic factors, and survival was presented with Kaplan-Meier curves. In the FP group, a significant curative effect was observed on the basis of pathological examination of postoperative lesions. However, the DOC group presented a significantly better prognosis on the basis of cumulative survival rates. Logistic regression analysis revealed that the presence of five or more lymph node metastases was an independent predictor of reduced survival. Patients with lymph node metastasis exhibited a better prognosis in the DOC group than those in the FP group. Preoperative CRT for locally advanced esophageal cancer using DOC results in similar or better long-term outcomes compared with FP-based CRT. Therefore, CRT using DOC is a promising therapy option for esophageal cancer.

Abstract
Gender-related risk factors in the survival of transplanted teeth with complete root formation have not yet been identified. The purpose of this study was to investigate gender differences in tooth autotransplantation at dental clinics. We asked participating dentists to provide information on transplantations they had undertaken from 1 January 1990 to 1931 December 2010. The data were screened to exclude patients who underwent more than one transplantation, smokers or those whose smoking habits were unknown, patients under 30 or who were 70 years old and over, cases where the transplanted teeth had incomplete root formation or multiple roots and those with fewer than 20 present teeth post-operation. We analysed 73 teeth of 73 males (mean age, 47.2 years) and 106 teeth of 106 females (mean age, 45.3 years) in this study. The cumulative survival rate and mean survival time were calculated using the Kaplan-Meier method. The cumulative survival rate for males was 88.3% at the 5-year mark, 64.8% at 10 years and 48.6% at 15 years; for females, it was 97.2% at the 5-year mark, 85.9% at 10 years and 85.9% at 15 years. A log-rank test indicated the difference between males and females to be significant (P = 0.011). There was also a significant difference in the main causes for the loss of transplanted teeth: males lost more transplanted teeth due to attachment loss than females (P < 0.05). These results indicate that males require more attention during the autotransplantation process, particularly at the stage of pre-operation evaluation and that of follow-up maintenance.
