BACKGROUND: Local ablative procedures such as cryo-surgery and thermo-ablation are increasingly employed as a supplement to liver resection for the therapy of primary and secondary liver tumors. It is still unclear if the survival time can be extended through local ablative procedures. This prospective study shows operative actions, complications and long-term follow-up of 19 patients undergoing cryotherapy. mETHODS: Between 1997 and 1998, 19 patients underwent cryotherapy due to a non-resectable malignant liver tumor (17 patients with metastases of a colon carcinoma, 2 patients with a hepatocellular carcinoma). Twelve patients (63.2%) received cryotherapy only and seven patients (36.8%) received a combination of resection and cryotherapy. The median follow-up period was 23 months. RESULTS: In a total of 59 liver tumors (18 were resected and 41 received cryotherapy), 12 had cryotherapy only, and 7 had a combination of cryotherapy and resection. The 30-day lethality was 0%, and the rate of major complications was 21%. After one year, 27.3% of the patients were still recurrence- free. The recurrence rate for all tumors treated was 58.8%. The median survival time for all patients was 21 months. The one- and three-year survival rates were 62. 5% and 15.8%, respectively. CONCLUSIONS: The mortality for cryotherapy is low, but there is a high rate of complications and long-term tumor control is not sufficient. If local ablative procedures of hepatic lesions are to be performed, not laparotomy but percutaneous, percutaneous thermoablation should be discussed as an alternative therapeutic measure.

AIm To investigate the acute effects of stochastic resonance whole body vibration(SR-WBV), including muscle relaxation and cardiovascular *** Sixty-four healthy students participated. The participants were randomly assigned to sham SR-WBV training at a low intensity(1.5 Hz) or a verum SR-WBV training at a higher intensity(5 Hz). Systolic blood pressure(SBp), diastolic blood pressure(DBp), heart rate(HR) and selfreported muscle relaxation were assessed before and immediately after *** Two factorial analyses of variance(ANOVA) showed a significant interaction between pre- vs post-SR-WBVmeasurements and SR-WBV conditions for muscle relaxation in the neck and back [F(1,55) = 3.35, p = 0.048, η2 = 0.07]. muscle relaxation in the neck and back increased in verum SR-WBV, but not in sham SR-WBV. No significant changes between pre- and post-training levels of SBD, DBD and HR were observed either in sham or verum SR-WBV conditions. With verum SR-WBV, improved muscle relaxation was the most significant in participants who reported the experience of back, neck or shoulder pain more than once a month(p muscle relaxation in young healthy individuals, while cardiovascular load was low. An increase in musculoskeletal relaxation in the neck and back is a potential mediator of pain reduction in preventive worksite SR-WBV trials.

managers and regulators are concerned about potential human health effects from exposure on lands contaminated by chemicals and radionuclides. Determining target cleanup levels is partly dependent upon future land use, and potential exposure from human use. This paper provides data from surveys of activity patterns of people attending festivals in four states, located in the vicinity of Department of Energy facilities. There were significant differences in both participation rates, and activity rates as a function of both location and ethnicity that can be used by managers to track exposure, land use, and preferred activities on natural lands. In general, 1) a higher percent of Native Americans engaged in consumptive activities than others, 2) a higher percent of Caucasians engaged in some non-consumptive activities than Native Americans, 3) a higher percentage of Native Americans engaged in activities on sacred grounds, 4) activity rates were generally higher for Native Americans for consumptive activities and religious/cultural than for Caucasians, 5) fishing rates were higher than other consumptive activities, and camping/hiking were higher than other non-con- sumptive activities, and 6) hunting rates were higher in subjects from Idaho than elsewhere. Baseline human use is critical for monitoring potential exposure, and provides the basis for monitoring, risk assessment and future land use, and these data can be used by managers for assessment and management. Tracking changes over time will reflect changing recreational, subsistence, and cultural/religious trends that relate to land use, public perceptions, and exposure.
