To summarize the results of treatment for sacral chordoma in Phase I-II and Phase II carbon ion radiotherapy trials for bone and soft-tissue sarcomas.We performed a retrospective analysis of 38 patients with medically unresectable sacral chordomas treated with the Heavy Ion Medical Accelerator in Chiba, Japan between 1996 and 2003. Of the 38 patients, 30 had not received previous treatment and 8 had locally recurrent tumor after previous resection. The applied carbon ion dose was 52.8-73.6 Gray equivalents (median, 70.4) in a total of 16 fixed fractions within 4 weeks.The median patient age was 66 years. The cranial tumor extension was S2 or greater in 31 patients. The median clinical target volume was 523 cm(3). The median follow-up period was 80 months. The 5-year overall survival rate was 86%, and the 5-year local control rate was 89%. After treatment, 27 of 30 patients with primary tumor remained ambulatory with or without supportive devices. Two patients experienced severe skin or soft-tissue complications requiring skin grafts.Carbon ion radiotherapy appears effective and safe in the treatment of patients with sacral chordoma and offers a promising alternative to surgery.

Minimally invasive treatment of symptomatic thyroid nodules is now commonplace. Ethanol ablation (EA) of thyroid cystic nodules has been performed since the 1990s, but there is no global consensus or guideline. Although various limitations of EA have been described, recommendations for practical application are necessary. Therefore, the Task Force Committee of the Korean Society of Thyroid Radiology initiated the present consensus statement and here we provide recommendations for the role of EA in the management of symptomatic thyroid nodules. These recommendations are based on evidence to date from the literature and expert opinion.

Synovial fluid was collected from the superior articular cavity of the temporomandibular joint in patients with unilateral internal derangement and joint pain whose contralateral joint was healthy. Glycosaminoglycans were liberated by digestion with pronase E, and precipitated with cetylpyridinium chloride and ethanol. Unsaturated disaccharide isomers of chondroitin sulfate, obtained following chondroitinase ACII digestion, were analyzed by high‐performance liquid chromatography. Analytic data indicated that ΔDi‐0S and ΔDi‐6S were often found in chondroitin sulfate from the fluid of the diseased joints. The amounts of ΔDi‐0S and ΔDi‐6S differed significantly between synovial fluid samples from the diseased and healthy joints. Comparison of the relative proportions of the unsaturated disaccharides in the synovial fluid with previously reported values for several tissues, indicated that the chondroitin sulfate originated from articular cartilage, with possibly some contributions from soft connective tissues and serum present in the synovial fluid. These results suggest that chondroitin sulfate in the synovial fluid provides a useful indicator of the degree of internal derangement of the temporomandibular joint.

The anticonvulsant effect of [(+/-)-2-[(inden-7-yloxy)methyl]morpholine (indeloxazine) HCl, a new cerebral activator, was investigated in rats against kindled seizures from the amygdala, an assumed model of secondarily generalized seizures in human. Indeloxazine (0.25-10 mg/kg, IP) dose-dependently depressed the kindled seizure and shortened the evoked amygdaloid afterdischarge. A high dose of indeloxazine (40 mg/kg, IP), however, induced generalized seizures. Comparison of the effects on the kindled seizures of indeloxazine to those of phenytoin, diazepam, ethanol, and imipramine revealed that the anticonvulsant actions of indeloxazine are similar to those of imipramine but not to those of phenytoin, ethanol, and diazepam. The results suggest that indeloxazine may exert its action through the monoaminergic system in the brain.

The Healthy City program is a comprehensive health promotion program implemented by local governments to improve citizens’ health. The Healthy City program aims to improve citizens’ quality of life through health promotion activities in daily life. It also improves health by eliminating health risk factors and increasing citizens’ happiness. Therefore, this study investigated the effects of the Healthy City program on the happiness index of local residents and the correlation between the Healthy City program and the happiness index using quality of life as a parameter. We conducted a questionnaire survey of residents of Seoul, where Healthy City networks are actively promoted. A total of 392 responses were obtained. Structural equations were used to analyze the collected data. The Healthy City program had positive effects on the happiness index. In other words, it increased the happiness index by improving the health of the local residents. Relevant policy efforts are also being made to advance health services through Healthy City programs. For an effective Healthy City program, it is necessary to implement policies regarding health equity, to expand Healthy City programs based on a settings approach, and to implement a sustainable Healthy City program through the establishment of Healthy City governance.

The impacts of climate change on human health have been observed and projected in the Philippines as vector-borne and heat-related diseases have and continue to increase. As a response, the Philippine government has given priority to climate change and health as one of the main research funding topics. To guide in identifying more specific research topics, a scoping review was done to complement the agenda-setting process by mapping out the extent of climate change and health research done in the country. Research articles and grey literature published from 1980 to 2017 were searched from online databases and search engines, and a total of 34 quantitative studies were selected. Fifty-three percent of the health topics studied were about mosquito-borne diseases, particularly dengue fever. Seventy-nine percent of the studies reported evidence of positive associations between climate factors and health outcomes. Recommended broad research themes for funding were health vulnerability, health adaptation, and co-benefits. Other notable recommendations were the development of open data and reproducible modeling schemes. In conclusion, the scoping review was useful in providing a background for research agenda-setting; however, additional analyses or consultations should be complementary for added depth.

Swimming behaviors in the forced swimming test have been reported to be depressed by stressors. Since toxic convulsion-inducing drugs related to dopamine [cocaine (COC)], benzodiazepine [methyl 6,7-dimethoxy-4-ethyl-beta-carboline-carboxylate (DMCM)], gamma-aminobutyric acid (GABA) [bicuculline (BIC)], and glutamate [N-methyl-D-aspartate (NMDA)] receptors can function as stressors, the present study compared their effects on the forced swimming behaviors with the effects of immobilization stress (IM) in rats. Their interactions with ethanol (EtOH), the most frequently coabused drug with COC which also induces convulsions as withdrawal symptoms but interferes with the convulsions caused by other drugs, were also investigated.Similar to the IM (10 min) group, depressed swimming behaviors (attenuated time until immobility and activity counts) were observed in the BIC (5 mg/kg IP) and DMCM (10 mg/kg IP) groups at the 5 h time point, after which no toxic behavioral symptoms were observed. However, they were normalized to the control levels at the 12 h point, with or without EtOH (1.5 g/kg IP). In the COC (60 mg/kg IP) and NMDA (200 mg/kg IP) groups, the depression occurred late (12 h point), and was normalized by the EtOH cotreatment. At the 5 h point, the COC treatment enhanced the swimming behaviors above the control level.Although the physiological stress (IM), BIC, and DMCM also depressed the swimming behaviors, a delayed occurrence and EtOH-induced recovery of depressed swimming were observed only in the COC and NMDA groups. This might be correlated with the previously-reported delayed responses of DA and NMDA neurons rather than direct effects of the drugs, which could be suppressed by EtOH. Furthermore, the characteristic psychostimulant effects of COC seemed to be correlated with an early enhancement of swimming behaviors.

Paclitaxel (PTX) is an essential anticancer drug used to treat breast cancer. Because it contains alcohol as a solvent, it is contraindicated in many Japanese breast cancer patients when they are suspected of alcohol intolerance. Aldehyde dehydrogenase 2 (ALDH2) is one of several enzymes that catalyzes dehydrogenation of aldehydes, and plays an important role in ethanol metabolism. Deficiency of this isozyme is believed to be responsible for facial flushing and other unpleasant symptoms following ethanol intake. In this study, we examined the safety of PTX for patients with the ALDH2 GA genotype.We performed ALDH2 genotyping on 25 patients with various cancers who were suspected to be intolerant to alcohol based on an interview using a simple question. Ten patients with the ALDH2 GA genotype, including 5 breast cancer patients, underwent chemotherapy containing PTX up to 100 mg/m2 (range 80-100 mg/m2), and were questioned about 16 alcohol-related symptoms at 11 timepoints to evaluate sensitivity to alcohol.All patients completed the first course of planned chemotherapy with either no or grade 1 alcohol-related symptoms.Our study suggests that PTX up to 100 mg/m2 can be used safely for patients with the ALDH2 GA genotype. To confirm the necessity of a genotyping test for ALDH2, further studies evaluating alcohol sensitivity in response to PTX among patients with the ALDH2 AA genotype are required.
