To expand the indications for high-dose-rate interstitial brachytherapy (HDR-ISBT) for deep-seated pelvic tumors, we investigated the usefulness of Doppler transrectal ultrasonography (TRUS) guidance and virtual planning. The patient was a 36-year-old female. She had right internal iliac lymph node oligometastasis of vaginal cancer 12 months after radical(More)
To improve treatment conformity for prostate cancer, we investigated daily applicator displacement during high-dose-rate interstitial brachytherapy (HDR-ISBT). Thirty patients treated with HDR-ISBT as monotherapy were examined. All patients received a treatment dosage of 49 Gy per 7 fractions over 4 days. For dose administration, we examined 376 flexible(More)
Assistive instruments such as slopes or textured paving blocks are installed in order to help elderly, sensory impaired and/or physically impaired people, who have any inconvenience to move outside. Though these precipitous situations of barrier-free progress affects their migration pathway for their destination, new barrier-free information are difficult(More)
Accessibility information can allow disabled people to identify suitable pathways to reach their destinations, but it is difficult to obtain new accessible pathway information rapidly because of limited local information disclosure. Thus, it is necessary to develop a comprehensive system that acquires barrier-free information from various sources and makes(More)
We investigated daily needle applicator displacement during multifractionated high-dose-rate interstitial brachytherapy (HDR-ISBT) for postoperative recurrent uterine cancer. Eight patients with postoperative recurrent uterine cancer received HDR-ISBT with or without external beam radiotherapy using our unique ambulatory technique. To analyze displacement,(More)
PURPOSE To choose the optimal brachytherapeutic modality for uterine cervical cancer, we performed simulation analysis. METHODS AND MATERIALS For each high-risk clinical target volume (HR CTV), we compared four modalities [classical conventional intracavitary brachytherapy (ConvICBT), Image-guided ICBT (IGICBT), intracavitary/interstitial brachytherapy(More)
Due to the Great East Japan Earthquake on 11 March 2011 and the following long-term earthquake swarm, many people living in the earthquake-affected areas have developed mental stress, even though clinically-diagnosable symptoms may not be apparent. Concurrently, many unusual reports have emerged in which persons complain of abnormally increased sensitivity(More)
The Tsugaru Strait is located between the Oshima Peninsula and the Shimokita/Tsugaru Peninsula, and connects the Sea of Japan with the Pacific Ocean (Fig. 1). In this area, warm and cold currents meet and mix, which allow a diverse biotic abundance. Cetaceans in this region have not been studied since the research of Kawamura et al. over 20 years ago, which(More)
OBJECTIVE To evaluate the efficacy of primary treatment for ovarian cancer from overall survival and progression-free survival. PATIENTS AND METHODS A total of 28 patients with epithelial ovarian cancer in stages III and IV who were primarily treated in our ward from 1993 were examined retrospectively. The Kaplan-Meier method and Harrington-Fleming test(More)
